Unless otherwise indicated, all information in this Prospectus assumes no exercise of the over-allotment options granted to the Underwriters and has been adjusted to reflect a five-for-one split of the Company's Common Stock effective on December 9, 1996 and the conversion of the Company's mandatorily redeemable convertible preferred stock (the "Convertible Preferred Stock") into 73,315,740 shares of Common Stock and the exercise of certain warrants to purchase 300,000 shares of Convertible Preferred Stock which are convertible into 1,500,000 shares of Common Stock upon the closing of the Offerings. THE COMPANY CIENA Corporation ("CIENA" or the "Company") designs, manufactures and sells dense wavelength division multiplexing ("DWDM") systems for long distance fiberoptic telecommunications networks. CIENA's DWDM solution, the MultiWave 1600 system, alleviates capacity, or bandwidth, constraints in high traffic fiberoptic routes without requiring the installation of new fiber. In addition, the MultiWave 1600 system enables flexible provisioning of additional bandwidth without requiring an upgrade of existing network transmission equipment. The MultiWave 1600 system can increase the carrying capacity of a single optical fiber 16 fold by allowing simultaneous transmission of up to 16 optical channels per fiber. This permits fiber currently carrying signals at transmission speeds of up to 2.5 gigabits per second ("Gb/s") to carry up to 40 Gb/s. CIENA's MultiWave 1600 system includes optical transmission terminals, optical amplifiers and network management software. CIENA's system is designed with an open architecture that allows the MultiWave 1600 system to interoperate with carriers' existing fiberoptic transmission systems having a broad range of transmission speeds and signal formats. The Company believes it is a worldwide market leader in field deployment of open architecture DWDM systems. CIENA's MultiWave 1600 system was introduced into field trials in the long distance network of Sprint Corporation ("Sprint") in May 1996 and LDDS WorldCom ("WorldCom") in August 1996. The MultiWave 1600 system began carrying live traffic in the Sprint network in October 1996. The Company has a three-year non-exclusive supply agreement with Sprint which expires in December 1998, a supply agreement with WorldCom which, subject to certain conditions, is exclusive through December 1997 and an agreement to supply Teleway Japan Corporation ("Teleway") with the Company's MultiWave 1600 system. Through October 31, 1996, the Company recorded $54.8 million in revenue, all of which was derived from sales of the MultiWave 1600 system to Sprint. The Company is actively seeking additional customers among other long distance carriers in the worldwide telecommunications market. The Company was incorporated in Delaware in November 1992. The Company's principal executive offices are located at 8530 Corridor Road, Savage, Maryland 20763, and its telephone number is (301) 317-5800.

CONCENTRATION OF POTENTIAL CUSTOMERS; DEPENDENCE ON MAJOR CUSTOMERS The Company has only three current customers and few potential customers, consisting almost exclusively of long distance telecommunications carriers. There are only a small number of long distance telecommunications carriers, and the substantial capital requirements involved in the establishment of long distance fiberoptic networks significantly limit additional entrants into this market. The Company's business will for the foreseeable future be dependent on this small number of existing and potential customers, and that number may decrease if and as customers merge with or acquire one another. All of the Company's revenue for the fiscal year ended October 31, 1996 was derived from Sprint, and substantially all of the Company's revenue for fiscal 1997 is expected to be derived from Sprint and WorldCom. WorldCom may terminate all or any part of an outstanding purchase order upon the payment of a termination fee, and the Company's agreements with WorldCom and Sprint do not require minimum purchase commitments. There can be no assurance the Company will be able to develop additional customers in the long distance telecommunications market. Accordingly, the loss of any one of the Company's customers, or the reduction, delay or cancellation of orders or a delay in shipment of the Company's products to such customers, could materially and adversely affect the Company's business, financial condition and results of operations. See "Management's Discussion and Analysis of Financial Condition and Results of Operations". The Company's dependence on sizable orders from very few customers makes the relationship between the Company and each customer critically important to the Company's business. While each customer relationship is typically structured around a detailed, heavily negotiated contract, as the relationship evolves over time, adjustments to such items as product specifications, laboratory and field testing plans, customer forecasts and delivery timetables, and installation and field support requirements may be required in response to customer demands and expectations. The inability of the Company to manage its customer relationships successfully would have a material adverse effect on the Company's business, financial condition and results of operations. RECENT PRODUCT INTRODUCTION The Company first began commercial shipments of its MultiWave 1600 system in May 1996. The Company's first operational systems only began carrying live traffic in October 1996 and therefore do not have a history of live traffic operation over an extended period of time. If reliability, quality or network monitoring problems should develop a number of material and adverse effects could result, including manufacturing rework costs, high service and warranty expense, high levels of product returns, delays in collecting accounts receivable, reduced orders from existing customers and declining level of interest from potential customers. The Company is aware of instances in which installation and activation of certain MultiWave 1600 systems have been delayed due to faulty components found in certain portions of these systems. Although the Company maintains accruals for product warranties, there can be no assurance that actual costs will not exceed these amounts. There is limited operating history of open architecture wavelength division multiplexing technology in fiberoptic networks, and in particular of MultiWave 1600 systems, and the equipment must be handled with care by trained installers. Accordingly, the Company expects there will be interruptions or delays from time to time in the activation of the systems, particularly because the Company does not control all aspects of the customer's installation and activation activities. If significant interruptions or delays occur, or if their cause is not promptly identified, diagnosed and resolved, confidence in the MultiWave 1600 system could be undermined. An undermining of confidence in the MultiWave 1600 system would materially and adversely affect the Company's customer relationships, business, financial condition and results of operations. 5 7 MANAGEMENT OF EXPANSION The Company is experiencing rapid expansion in all areas of its operations, particularly in manufacturing, and the Company anticipates that this expansion will continue in the near future. Total personnel has grown from 49 on October 31, 1995 to 225 on October 31, 1996, with 125 of the 176 new employees devoted to manufacturing. This expansion has placed strains on the managerial, financial and personnel resources of the Company and will continue to do so. The rapid pace and volume of new hiring could adversely affect the efficiency of the Company's manufacturing process. Any delays or difficulties in the Company's manufacturing process caused by these factors or others could make it difficult for the Company to meet its customers' requirements. The Company is in the process of substantially increasing its flow of materials, manufacturing capacity, optical assembly, final assembly and final component module and system test functions to respond to customer demand. The pace of the Company's expansion, in combination with the complexity of the technology involved in the manufacture of the Company's systems, demands an unusually high level of managerial effectiveness in anticipating, planning, coordinating and meeting the operational needs of the Company and the needs of the Company's customers for quality, reliability, timely delivery and post-installation field support. Given the small number of potential customers for the Company's systems, the adverse effect on the Company resulting from a lack of effective management in any of these areas will be magnified. The Company's key management employees have not had previous experience in managing companies undergoing such rapid expansion. Inability to manage the expansion of the Company's business could have a material adverse effect on its business, financial condition and results of operations. In addition, the Company's manufacturing expansion and related capital expenditures are being made in anticipation of a level of customer orders that has not been historically experienced by the Company and that may not be achieved. See "Management's Discussion and Analysis of Financial Condition and Results of Operations". DEPENDENCE ON A SINGLE PRODUCT -- THE MULTIWAVE 1600 SYSTEM The MultiWave 1600 system is the Company's only product and is focused exclusively on providing additional bandwidth to long distance telecommunications carriers. Accordingly, a softening or slowdown in demand for the Company's product or for additional bandwidth by long distance telecommunications carriers would materially and adversely affect the Company's business, financial condition and results of operations. There can be no assurance that the Company will be successful in developing any other products or taking other steps to reduce the risk associated with any softening or slowdown in the demand for additional bandwidth, nor is there any assurance the Company will be able to leverage successfully its DWDM technology into other network applications. Conversely, if the demand for additional bandwidth accelerates, there is no assurance that the Company's MultiWave 1600 system will deliver sufficient capacity as rapidly as needed, or that competing DWDM products from other vendors offering higher capacity would not displace or render obsolete the MultiWave 1600 system. FLUCTUATION IN QUARTERLY AND ANNUAL RESULTS The Company's revenue and operating results may vary significantly from quarter to quarter and from year to year as a result of a number of factors, including the size and timing of orders, product mix and shipments of systems. The timing of order placement, size of orders, satisfaction of contractual customer acceptance criteria, as well as order delays or deferrals and shipment delays and deferrals, may cause material fluctuations in revenue. Delivery of new equipment for installation is also likely to be deferred during the high telecommunications traffic periods in November and December so as not to risk network reliability problems. The Company's expense levels in the future will be partially based on its expectations of long term future revenue and as a result net income in any quarterly period in which material orders are shipped or delayed could vary significantly. Due to this likelihood of significant quarterly fluctuation in operating results, the Company believes quarter- to-quarter comparisons of its results of operations, particularly during the next two to three years of 6 8 operations, may not necessarily be meaningful indicators of year-to-year performance. See "Management's Discussion and Analysis of Financial Condition and Results of Operations". LONG AND UNPREDICTABLE SALES CYCLES The Company expects that the period of time between initial customer contact and an actual purchase order may span a year or more. In addition, even when committed to proceed with deployment of equipment, long distance telecommunications carriers typically undertake extensive and lengthy product evaluation and factory acceptance and field testing of new equipment before purchasing and installing any of it in their networks. Additionally, the purchase of network equipment such as DWDM equipment is typically carried out by network operators pursuant to multiyear purchasing programs which may increase or decrease annually as the operators adjust their capital equipment budgets and purchasing priorities. The Company's customers do not typically share information on the duration or magnitude of planned purchasing programs, nor do they consistently provide to the Company advance notice of contemplated changes in their capital equipment budgets and purchasing priorities. These uncertainties substantially complicate the Company's manufacturing planning. Curtailment or termination of customer purchasing programs, decreases in customer capital budgets or reduction in the purchasing priority assigned to equipment such as DWDM equipment, particularly if significant and unanticipated by the Company, could have a material adverse effect on the Company's business, financial condition and results of operations. Long distance carriers may also encounter delays in their build out of new routes or in their installation of new equipment in existing routes, with the result that orders for the MultiWave 1600 system may be delayed or deferred. Any delay or deferral of orders for the MultiWave 1600 system would have a material adverse effect on the Company's business, financial condition and results of operations. COMPETITION The competition to achieve higher and more cost-effective bandwidth in the global telecommunications industry is intense and is dominated by a small number of very large companies with greater financial, technical and marketing resources, greater manufacturing capacity and more established customer relationships with network operators than the Company. Each of Lucent Technologies Inc., formerly part of AT&T Corporation ("Lucent"), Alcatel Alsthom Group ("Alcatel"), Northern Telecom Inc. ("Nortel"), NEC Corporation ("NEC"), Pirelli SpA ("Pirelli"), Siemens AG ("Siemens") and ECI Telecom Ltd. ("ECI") offer various forms of alternative transmission enhancing equipment and in some cases are offering or have announced an intention to offer DWDM equipment. Such competitors use their advantages in resources and alternative equipment in different ways. For example, Lucent, Alcatel, Nortel, NEC and Siemens are already providers of a full complement of switches, fiberoptic transmission terminals and fiberoptic signal regenerators and thereby can position themselves as vertically integrated, "one-stop shopping" solution providers to potential customers. Further, in certain cases, competitors have offered the Company's target customers, on an immediate delivery basis, off-the-shelf time division multiplexing ("TDM") transmission equipment at comparatively lower prices, with a promise to upgrade to DWDM or other improved equipment in the future. The substantial system integration resources and manufacturing capability of the TDM suppliers, in combination with any difference in timeliness of delivery, can be important to long distance network operators. Finally, as and when these competitors are able to offer DWDM systems in combination with their own fiberoptic transmission terminals, they can be expected to press further on the attractiveness of a "one-stop shopping" solution. The Company expects competition in general to intensify substantially, especially over the next few quarters, and further expects competition to be broadly based on varying combinations of price, manufacturing capacity, timely delivery, system reliability, service commitment and installed customer base, as well as on the comprehensiveness of the system solution in meeting immediate network needs and foreseeable scaleability requirements. There can be no assurance that the Company will be able to compete successfully with its existing or new competitors or that competitive pressures faced by the Company will not result in lower prices for the Company's 7 9 products and otherwise materially and adversely affect its business, financial condition and results of operations. TECHNOLOGICAL CHANGE AND NEW PRODUCTS The Company expects that new technologies will emerge as competition in the telecommunications industry increases and the need for higher and more cost efficient bandwidth expands. The Company's ability to anticipate changes in technology, industry standards, customer requirements and product offerings and to develop and introduce new and enhanced products will be significant factors in the Company's ability to remain a leader in the deployment of open architecture DWDM systems. The market for telecommunications equipment is characterized by substantial capital investment and diverse and competing technologies such as fiberoptic, cable, wireless and satellite technologies. The accelerating pace of deregulation in the telecommunications industry will likely intensify the competition for improved technology. Many of the Company's competitors have substantially greater financial, technical and marketing resources and manufacturing capacity with which to compete for new technologies and for market acceptance of their products. The introduction of new products embodying new technologies or the emergence of new industry standards could render the Company's existing product uncompetitive from a pricing standpoint, obsolete or unmarketable. Any of these outcomes would have a material and adverse effect on the Company's business, financial condition and results of operations. PROPRIETARY RIGHTS The Company relies on patents, contractual rights, trade secrets, trademarks and copyrights to establish and protect its proprietary rights in its product. While the Company does not expect that its proprietary rights in its technology will prevent competitors from developing technologies and products functionally similar to the Company's, the Company believes many aspects of its DWDM technologies and know-how are proprietary, and intends to monitor closely the DWDM products introduced by competitors for any infringement of the Company's proprietary rights. Additionally, the Company expects that DWDM technologies and know-how in general will become increasingly valuable intellectual properties as the competition to achieve higher and more cost effective bandwidth intensifies. The Company believes this increasing value in an industry marked by a few very large competing suppliers represents a competitive environment where intellectual property disputes are likely. Such disputes may be initiated by competitors against the Company for tactical purposes to gain competitive advantage or overcome competitive disadvantage, even if the merits of a specific dispute are doubtful. As a result, in the future, litigation may be necessary to enforce any patents issued or assigned to the Company, to protect trademarks, trade secrets and other intellectual property rights owned by the Company, to defend the Company against claimed infringement of the rights of others and to determine the scope and validity of the proprietary rights of others. Any litigation could be costly and a diversion of management's attention, which could have a material adverse effect on the Company's business, financial condition and results of operations. Adverse determinations in litigation could result in the loss of the Company's proprietary rights, subject the Company to significant liabilities, require the Company to seek licenses from third parties or prevent the Company from manufacturing or selling its products, any of which could have a material adverse effect on the Company's business, financial condition and results of operations. The Company has received, and may receive in the future, notices from holders of patents in the optical technology field that raise issues as to possible infringement by the Company's products. Pirelli sent a notice in December 1995 identifying eleven patents it possesses in the field of optical communications. The Company believes the MultiWave 1600 system does not infringe the patents cited in the notices received. However, questions of infringement in the field of DWDM technologies involve highly technical and subjective analyses. There can be no assurance that any such patent holders or others will not in the future initiate legal proceedings against the Company or that, if any such proceedings were initiated, the Company would be successful in defending against these actions. Even if the Company is successful in defending against any such actions, these actions 8 10 could have an adverse effect on existing and potential customer relationships and therefore could have a material adverse effect on the Company's business, financial condition and results of operations. The Company has agreed to indemnify Sprint, WorldCom and Teleway for liability that may be incurred in connection with the infringement of a third party's intellectual property rights and expects that it will be requested to agree to indemnify other potential customers in the future. There can be no assurance that such indemnification against alleged liability will not be required from the Company in the future. Patent applications in the United States are not publicly disclosed until the patent issues. The Company anticipates that several competitors may have patent applications in progress that, if issued, could relate to the Company's products. If such patents were to issue, there can be no assurance that the patent holders or licensees will not assert infringement claims against the Company or that such claims will not be successful. The Company could incur substantial costs in defending itself and its customers against any such claims, regardless of the merits of such claims. Parties making such claims may be able to obtain injunctive or other equitable relief which could effectively block the Company's ability to sell its products, and each claim could result in an award of substantial damages. In the event of a successful claim of infringement, the Company and its customers may be required to obtain one or more licenses from third parties. There can be no assurance that the Company or its customers could obtain necessary licenses from third parties at a reasonable or acceptable cost or at all. Substantial inventories of intellectual property are held by a few industry participants, such as Bell Laboratories (now owned by Lucent) and major universities and research laboratories. This concentration of intellectual property in the hands of a few major entities also poses certain risks to the Company in seeking to hire qualified personnel. The Company has on a few occasions recruited such personnel from competitors. The Company has in the past received letters from counsel to Lucent asserting that the hiring of their personnel compromises Lucent's intellectual property. There can be no assurance that other companies will not claim the misappropriation or infringement of their intellectual property, particularly when and if employees of these companies leave to work for the Company. To date, the Company has not experienced litigation concerning the assertions by Lucent, and believes there is no basis for claims against the Company. Nevertheless, there can be no assurance that the Company will be able to avoid litigation in the future, particularly if new employees join the Company after having worked for a competing company. Such litigation could be very expensive to defend, regardless of the merits of the claims. DEPENDENCE ON SUPPLIERS Suppliers in the specialized, high technology sector of the optical communications industry are generally not as plentiful or, in some cases, as reliable, as suppliers in more mature industries. The Company is dependent on a limited number of suppliers for components of the MultiWave 1600 system as well as equipment used to manufacture the MultiWave 1600 system. The MultiWave 1600 system has over 600 components, and certain key optical and electronic components are currently available only from a sole source, where the Company has identified no other supplier for the component. While alternative suppliers have been identified for certain other key optical and electronic components, those alternative sources have not been qualified by the Company. The Company has to date conducted its business with suppliers through the issuance of conventional purchase orders against the Company's forecasted requirements. The Company is seeking to negotiate long term supply agreements with key suppliers, but currently has no such agreements. The Company has from time to time experienced minor delays in the receipt of key components, and any future difficulty in obtaining sufficient and timely delivery of them could result in delays or reductions in product shipments which, in turn, could have a material adverse effect on the Company's business, financial condition and results of operations. In addition, the Company's strategy to have portions of its final product assembled and, in certain cases, tested, by third parties involves certain risks, including the potential absence of adequate capacity, the unavailability of or interruptions in access to certain process technologies, and reduced control over delivery sched- 9 11 ules, manufacturing yields, quality and costs. In the event that any significant supplier or subcontractor were to become unable or unwilling to continue to manufacture and/or test the Company's systems in required volumes, the Company would have to identify and qualify acceptable replacements. This process could also be lengthy and no assurance can be given that any additional sources would become available to the Company on a timely basis. A key item of equipment used to manufacture the MultiWave 1600 system is available only from a sole source. A delay or reduction in component or equipment shipments, an increase in component or equipment costs or a delay or increase in costs in the assembly and testing of products by third party subcontractors could materially and adversely affect the Company's business, financial condition and results of operations. COMPETITORS AS SUPPLIERS Certain of the Company's component suppliers are both primary sources for such components and major competitors in the market for system equipment. For example, the Company buys certain key components from Lucent, Alcatel, Nortel, NEC and Siemens, each of which offers optical communications systems and equipment which are competitive with the Company's MultiWave 1600 system. Lucent is the sole source of two integrated circuits and is one of two suppliers of Erbium-doped fiber. Alcatel and Nortel are suppliers of lasers used in the MultiWave 1600 system. NEC is a supplier of certain testing equipment. The Company's business, financial condition and results of operations could be materially and adversely affected if these supply relationships were to decline in reliability or otherwise change in any manner adverse to the Company. LIMITED OPERATING HISTORY; HISTORY OF LOSSES The Company was founded in November 1992 and introduced its MultiWave 1600 system in field trials in May 1996. Accordingly, the Company has only a limited operating history upon which an evaluation of the Company, its product and prospects can be based. The Company's prospects must be considered in light of the risks, expenses and difficulties frequently encountered by companies in their early stage of development, particularly companies in new and rapidly evolving markets and companies experiencing rapid expansion in their operations. To address these risks, the Company must, among other things, respond to competitive developments, continue to attract, retain and motivate qualified management and other employees, continue to upgrade its technologies and commercialize products and services which incorporate such technologies and achieve market acceptance for its MultiWave 1600 system. There can be no assurance that the Company will be successful in addressing such risks. The Company incurred net losses in each quarter from inception through the second quarter of fiscal 1996. While the Company reported net income for fiscal 1996, there can be no assurance that the Company will sustain profitability. See "Management's Discussion and Analysis of Financial Condition and Results of Operations". DEPENDENCE ON KEY PERSONNEL The Company's success depends to a significant extent upon a number of key technical and management employees. The loss of the services of any of the Company's key employees, none of whom is bound to a term of employment by an employment agreement, would have a material adverse effect on the Company. The Company generally does not maintain insurance policies on the lives of such employees. The Company's success will also depend in large part upon its ability to attract and retain highly-skilled technical, managerial, sales and marketing personnel, particularly those skilled and experienced with optical communications equipment. Competition for such personnel is intense and there can be no assurance that the Company will be successful in retaining its existing key personnel and in attracting and retaining the personnel it requires. Failure to attract and retain key personnel will have a material adverse effect on the Company's business, financial condition and results of operations. 10 12 DISCRETIONARY USE OF PROCEEDS The net proceeds to the Company from the Offerings, estimated at approximately $82.6 million, will be used for general corporate purposes and have not been designated for any particular purpose. Accordingly, the Company will have broad discretion as to the application of such proceeds. See "Use of Proceeds". SHARES ELIGIBLE FOR FUTURE SALE Sales of substantial amounts of Common Stock in the public market after the Offerings could adversely affect prevailing market prices for the Common Stock. The 5,000,000 shares of Common Stock offered hereby will be freely tradeable without restriction in the public market as of the date of this Prospectus. Beginning 90 days after the date of this Prospectus, approximately shares will become eligible for sale in the public market, subject in some cases to the volume and other restrictions of Rule 144 under the Securities Act of 1933, as amended (the "Securities Act"). Of these shares, holders of shares and options and warrants to purchase shares are subject to lock-up agreements. Shares covered by these lock-up agreements are subject to restrictions on resale in the public market for a period of 180 days following the date of this Prospectus, subject to release, directly or indirectly at the discretion of the Representatives of the Underwriters. Upon the expiration of the lock-up period, approximately shares will become eligible for sale in the public market subject in some cases to the volume and other restrictions of Rule 144 under the Securities Act. The holders of approximately 74,815,680 shares of Common Stock are entitled to certain registration rights with respect to such shares under the Securities Act. In addition, the Company intends to file a registration statement under the Securities Act promptly following the effective date of this Registration Statement to register all of the shares of Common Stock issued or reserved for issuance upon the exercise of options issued or that may be issued under the Company's Amended and Restated 1994 Stock Option Plan and 1996 Outside Directors Stock Option Plan. As of October 31, 1996, there were outstanding options for the purchase of 11,032,960 shares, of which options for approximately 2,684,355 shares were vested. See "Management -- Stock Plans," "Underwriting" and "Shares Eligible for Future Sale". NO PRIOR MARKET; POSSIBLE VOLATILITY OF STOCK PRICE Prior to the Offerings, there has been no public market for the Common Stock of the Company. The initial public offering price will be determined by negotiations among the Company and the Representatives of the Underwriters. See "Underwriting" for a discussion of the factors to be considered in determining the initial public offering price. There can be no assurance that an active public market will develop or be sustained after the Offerings or that the market price of the Common Stock will not decline below the public offering price. Future announcements concerning the Company or its competitors, quarterly variations in operating results, announcements of technological innovations, the introduction of new products or changes in product pricing policies by the Company or its competitors, proprietary rights or product liability litigation or changes in earnings estimates by analysts could cause the market price of the Common Stock to fluctuate substantially. In addition, stock prices for many technology companies fluctuate widely for reasons which may be unrelated to operating results. These fluctuations, as well as general economic, political and market conditions such as recessions, international instabilities or military conflicts, may materially and adversely affect the market price of the Common Stock. CONTROL BY EXISTING STOCKHOLDERS The Company's officers, directors and their affiliates will, in the aggregate, beneficially own approximately 54.7% of the Company's outstanding shares after the Offerings. As a result, these stockholders, if acting together, would be able effectively to control substantially all matters requiring approval by the stockholders of the Company, including the election of directors. This ability may have the effect of delaying or preventing a change in control of the Company, or causing 11 13 a change in control of the Company which may not be favored by the Company's other stockholders. EFFECT OF CERTAIN CHARTER, BYLAW AND OTHER PROVISIONS Certain provisions of the Company's Third Amended and Restated Certificate of Incorporation, as amended (the "Certificate of Incorporation"), and bylaws and certain other contractual provisions could have the effect of making it more difficult for a third party to acquire, or of discouraging a third party from attempting to acquire, control of the Company. Such provisions could limit the price that certain investors might be willing to pay in the future for shares of the Company's Common Stock. Certain of these provisions allow the Company to issue preferred stock with rights senior to those of the Common Stock without any further vote or action by the stockholders, provide for a classified board of directors, eliminate the right of the stockholders to call a special meeting of stockholders, eliminate the right of stockholders to act by written consent, and impose various procedural and other requirements which could make it difficult for stockholders to effect certain corporate actions. LITIGATION The Company and certain directors are defendants in a lawsuit recently brought by entities controlled by a stockholder of the Company concerning alleged entitlement to additional shares of Convertible Preferred Stock. See "Business -- Legal Proceedings". No assurance can be given that this lawsuit will not result in an adverse effect on the Company's business, financial condition or results of operations. IMMEDIATE AND SUBSTANTIAL DILUTION Purchasers of the Common Stock offered hereby will suffer immediate and substantial dilution of $16.62 per share in the net tangible book value of the Common Stock from the initial public offering price (at an assumed initial public offering price of $18.00 per share). To the extent outstanding options to purchase the Company's Common Stock are exercised, there will be further dilution. See "Dilution". 12 14 USE OF PROCEEDS The principal purpose of the Offerings is to increase the Company's working capital and equity base, create a public market for the Company's Common Stock, facilitate future access to public capital markets and provide increased visibility and credibility for the Company in its marketplace. The net proceeds to the Company from the sale of the 5,000,000 shares of Common Stock offered by the Company hereby are estimated to be approximately $82.6 million ($95.2 million if the over-allotment options are exercised in full) at an assumed initial public offering price of $18.00 per share, after deducting the underwriting discount and estimated offering expenses. The Company also expects to receive additional proceeds of approximately $0.6 million from the exercise of certain outstanding warrants to purchase 300,000 shares of Convertible Preferred Stock which are convertible into 1,500,000 shares of Common Stock. The Company has no current plans for the net proceeds of the Offerings. The Company intends to add the net proceeds from the Offerings and from the exercise of warrants to working capital, where such proceeds will be available to support general corporate purposes which are expected to include capital equipment expenditures to support selling and marketing, manufacturing and product development activities. A portion of the proceeds may also be used to acquire or invest in complementary businesses or products or to obtain the right to use complementary technologies. From time to time, in the ordinary course of business, the Company evaluates potential acquisitions of such businesses, products or technologies. However, the Company has no present understandings, commitments or agreements with respect to any material acquisition of other businesses, products or technologies. Pending use of the net proceeds for any purposes, the Company intends to invest such funds in short-term, interest-bearing, investment grade obligations. DIVIDEND POLICY The Company has never paid or declared any cash dividends on its capital stock. It is the present policy of the Company to retain earnings to finance the growth and development of the business and, therefore, the Company does not anticipate declaring or paying cash dividends on its Common Stock in the foreseeable future. In addition, the Company's credit agreement with Mercantile-Safe Deposit & Trust Company prohibits the Company from paying cash dividends on its capital stock. 13 15 CAPITALIZATION The following table sets forth the capitalization of the Company as of October 31, 1996 (i) on an actual basis and (ii) as adjusted to reflect the exercise of certain outstanding warrants to purchase 300,000 shares of Convertible Preferred Stock which are convertible into 1,500,000 shares of Common Stock of the Company, the conversion of all outstanding shares of Convertible Preferred Stock into 73,315,740 shares of Common Stock upon the closing of the Offerings and the sale of 5,000,000 shares of Common Stock offered by the Company hereby (at an assumed initial public offering price of $18.00 per share) and the application of the estimated net proceeds therefrom. This table should be read in conjunction with the Company's financial statements and notes thereto appearing elsewhere in this Prospectus.

Also excludes 675,000 shares of Common Stock reserved for issuance pursuant to the exercise of warrants outstanding as of October 31, 1996. See "Management -- Stock Plans" and Note 9 of Notes to Financial Statements. 14 16 DILUTION The pro forma net tangible book value of the Company as of October 31, 1996 was $46.0 million or approximately $.52 per share of Common Stock. Pro forma net tangible book value per share represents the amount of the Company's pro forma stockholders' equity, less intangible assets, divided by 88,007,325 pro forma shares of Common Stock outstanding as of October 31, 1996. The preceding pro forma information gives effect to (i) the conversion of the Company's Convertible Preferred Stock into 73,315,740 shares of Common Stock and (ii) the exercise of certain warrants to purchase 300,000 shares of Convertible Preferred Stock which are convertible into 1,500,000 shares of Common Stock. Assuming the sale by the Company of 5,000,000 shares of Common Stock offered hereby at an assumed initial public offering price of $18.00 per share and receipt of the estimated net proceeds therefrom, the pro forma adjusted net tangible book value of the Company as of October 31, 1996 would have been approximately $128.6 million or $1.38 per share. This represents an immediate increase in such net tangible book value of $.86 per share to existing stockholders and an immediate dilution of $16.62 per share to new investors. The following table illustrates this per share dilution: Assumed initial public offering price per share...................... $ 18.00 Pro forma net tangible book value per share as of October 31, 1996........................................................... $.52 Increase per share of Common Stock attributable to the Offerings...................................................... .86 ---- Pro forma net tangible book value per share after the Offerings...... 1.38 ------- Net tangible book value dilution per share to new investors.......... $ 16.62 =======
The following table summarizes, on a pro forma basis as of October 31, 1996, the total number of shares of Common Stock purchased from the Company, the total consideration paid to the Company and the average price per share paid, by existing stockholders and by new investors (at an assumed initial public offering price of $18.00 per share and without giving effect to the underwriting discount and estimated offering expenses):

- --------------- (1) The Company has a 52 or 53 week fiscal year which ends on the Saturday nearest to the last day of October in each year. For purposes of financial statement presentation, each fiscal year is described as having ended on October 31. Fiscal 1994 and 1995 comprised 52 weeks and fiscal 1996 comprised 53 weeks. (2) The pro forma weighted average common and common equivalent shares outstanding for the year ended October 31, 1996 was 99,107,000. Pro forma net income per common and common equivalent share is computed using the weighted average number of common and common equivalent shares outstanding. Weighted average common and common equivalent shares include Common Stock, stock options and warrants using the modified treasury stock method and the assumed conversion of all outstanding shares of Convertible Preferred Stock into Common Stock. See Note 1 of Notes to Financial Statements. 16 18 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS The following discussion and analysis should be read in conjunction with "Selected Financial Data" and the Company's financial statements and notes thereto included elsewhere in this Prospectus. The information in this Prospectus contains certain forward-looking statements that involve risks and uncertainties. The Company's actual results may differ materially from the results discussed in the forward-looking statements. Factors that might cause such a difference include, but are not limited to, those discussed in "Risk Factors", "Management's Discussion and Analysis of Financial Condition and Results of Operations" and "Business" as well as those discussed elsewhere in this Prospectus. OVERVIEW CIENA was incorporated in November 1992. From incorporation through April 1994, the Company's principal objective was to secure sufficient equity financing to enable the Company to commence product development efforts based on its optical communications technology. The Company secured its initial round of equity financing in April 1994. The engineering design and development efforts begun in April 1994 took on greater product focus in early 1995 as the Company began working with Sprint to refine the Company's design of its DWDM system to meet Sprint's requirements. Satisfactory preliminary laboratory testing at Sprint in October 1995 led to the execution of a three-year non-exclusive supply agreement in December 1995. The agreement called for factory acceptance testing, followed by field testing, prior to any obligation of Sprint to pay for any systems. The Company passed the factory acceptance testing in April 1996, and shipped commercially deployable systems for field testing in May 1996. Field testing was satisfactorily passed in July 1996, and live traffic began being carried over the Company's MultiWave 1600 system in October 1996. The Company made initial contact with WorldCom in February 1995 and WorldCom agreed in July 1996 to commence field testing of the MultiWave 1600 system in August 1996. A supply agreement with WorldCom, which, subject to certain conditions, is exclusive through December 1997, was signed in September 1996. The Company also has shipped a MultiWave 1600 system for Teleway's network in Japan. The Company recognizes product revenue in accordance with the shipping terms specified. For transactions where the Company has yet to obtain customer acceptance or has agreements pertaining to installation services, revenue is deferred until no significant obligations remain. Revenue for installation services is recognized as the services are performed. Amounts received in excess of revenue recognized are recorded as deferred revenue. For distributor sales where risks of ownership have not transferred, the Company recognizes revenue when the product is shipped through to the end user. The Company's initial recognition of revenue from Sprint occurred in the quarter ended July 31, 1996, after notification by Sprint of satisfactory completion of field testing. All of the Company's revenue of $54.8 million through October 31, 1996 was derived from MultiWave 1600 system sales to Sprint. The Company is currently engaged in continued efforts to expand its manufacturing capabilities. Approximately one-third of the Company's current 50,500 square foot facility in Savage, Maryland is used for manufacturing operations; the Company intends to convert the entire facility to manufacturing operations by April 30, 1997, while transferring other operating functions to an approximately 96,000 square foot facility, approximately 10 miles from Savage, near the Baltimore/Washington International Airport. RESULTS OF OPERATIONS FISCAL YEARS ENDED 1994, 1995 AND 1996 For the fiscal years ended October 31, 1994 and 1995, the Company was in the development stage, generated no revenue and had losses from operations of $2.4 million and $7.7 million, respectively. By the end of fiscal year 1995, the Company had begun to devote substantial resources to the development of manufacturing capabilities and the expansion of its selling and marketing efforts and general and administrative support infrastructure. The level of expenditures increased toward the end of fiscal 1996, as increased demand for the Company's MultiWave 1600 system required rapid expansion of manufacturing capabilities and of technical and field support 17 19 staff. For the fiscal year ended October 31, 1996, the Company generated revenue of $54.8 million, had gross profit of $33.0 million and incurred operating expenses of $16.6 million. QUARTERLY RESULTS OF OPERATIONS The tables below set forth the operating results and percentage of revenue represented by certain items in the Company's statements of operations for each of the four quarters in the fiscal year ended October 31, 1996. This information is unaudited, but in the opinion of the Company reflects all adjustments (consisting only of normal recurring adjustments) that the Company considers necessary for a fair presentation of such information in accordance with generally accepted accounting principles. The results for any quarter are not necessarily indicative of results for any future period. Operating results as a percentage of revenue for the quarters ended January 31 and April 30, 1996 are excluded due to the absence of revenue for those periods:

THREE MONTHS ENDED JANUARY 31, 1996, APRIL 30, 1996, JULY 31, 1996 AND OCTOBER 31, 1996 REVENUE. The Company began shipping the MultiWave 1600 system for field testing in May 1996 with customer acceptance by Sprint occurring in July 1996. Revenue totalled $16.9 million for the quarter ended July 31, 1996. Revenue for the quarter ended October 31, 1996 increased 124% over the previous quarter to $37.9 million. The increase in revenue from quarter to quarter was due to the increased sales to Sprint influenced by increases in the Company's manufacturing capacity and customer confidence. While the Company achieved quarter to quarter revenue growth 18 20 of 124% from the third to fourth quarters of fiscal 1996, the Company does not expect to sustain this rate of sequential quarterly revenue growth in future periods. See "Risk Factors". GROSS PROFIT. Cost of goods sold consists of component costs, direct compensation costs, warranty and other contractual obligations, royalties, license fees and overhead related to the Company's manufacturing operations. Gross margins were 56.6% and 61.8% for the quarters ended July 31, 1996 and October 31, 1996, respectively. The increase in gross margin was affected by fixed overhead costs being allocated over a larger revenue base and an improvement in manufacturing efficiencies. The Company's gross margins in the future may be affected by a number of factors, including competitive market pricing, manufacturing volumes and efficiencies and fluctuations in component costs. The Company's future gross margins may also be affected by the mix of product features and configurations sold in a period as well as the extent of services provided. RESEARCH AND DEVELOPMENT EXPENSES. Research and development expenses consist of compensation costs for research and development staff, depreciation of test equipment, certain software development costs and prototype materials. Research and development expenses fluctuated from $2.5 million for the quarter ended January 31, 1996 to $1.7 million, $2.0 million and $2.7 million for the quarters ended April 30, July 31 and October 31, 1996, respectively. First quarter activity was attributable in part to selecting materials and equipment while building prototype systems which in turn supported the development activities for the second and third quarters. The fourth quarter development expenditures of $2.7 million, which were significantly greater in absolute dollars than the previous two quarters, were related to increased staffing levels, outside consulting services and the purchase of prototype materials for the development of the optical add/drop multiplexer. During the third and fourth quarters, research and development expenses were 11.6% and 7.2% of revenue, respectively. The decrease in research and development expenses as a percentage of revenue from quarter to quarter was a function of the rapid revenue growth. The Company expects that its research and development expenditures will generally continue to increase in absolute dollars during fiscal 1997 to support the continued development of new MultiWave features and products and develop possible product cost reductions. The Company has expensed research and development costs as incurred. SELLING AND MARKETING EXPENSES. Selling and marketing expenses consist of compensation costs for selling and marketing staff, certain pre-sales and post-sales support, travel expenses, trade shows and other marketing programs. Selling and marketing expenses increased from quarter to quarter during fiscal year 1996. The costs incurred were $0.5 million, $0.7 million, $1.1 million and $1.5 million for the quarters ended January 31, April 30, July 31, and October 31, 1996, respectively. The quarterly increases were primarily the result of increased payroll costs reflecting the hiring of new employees for sales, technical assistance and field support for the Company's customers. Other factors contributing to the increases in the third and fourth quarters included commissions earned and trade show participation. During the third and fourth quarters, selling and marketing expenses were 6.7% and 3.8% of revenue, respectively. The decrease in selling and marketing expenses as a percentage of revenue was a function of the rapid revenue growth. The Company anticipates that its selling and marketing expenses will increase in absolute dollars during fiscal 1997 as additional personnel are hired and offices are opened to allow the Company to pursue new market opportunities and service new customers. GENERAL AND ADMINISTRATIVE EXPENSES. General and administrative expenses consist principally of expenses for finance, administration and general management activities. The expenses totalled $0.5 million, $0.5 million, $1.1 million and $1.8 million for the quarters ended January 31, April 30, July 31, and October 31, 1996, respectively. The increases in general and administrative expenses in the third and fourth quarters compared to the first and second quarters were primarily due to increased staffing. The Company also incurred significant legal expenses in the fourth quarter of 1996 in connection with certain litigation. The Company believes that its general and administrative expenses will increase in fiscal 1997 as a result of the expansion of the Company's 19 21 administrative staff required to support its expanding operations and an increase in expenses associated with operating as a public company. OTHER INCOME (EXPENSE), NET. Other income (expense), net, consists of interest income earned on the Company's cash and cash equivalents, net of interest expense associated with the Company's debt obligations. The Company believes that other income (expense), net, will fluctuate from quarter to quarter primarily depending upon the level of the Company's cash balances, funding required for daily operations and the retirement of its debt obligations. The Company believes that other income will increase in absolute dollars in fiscal 1997 as a result of the investment of the net proceeds of the Offerings. PROVISION (BENEFIT) FOR INCOME TAXES. During fiscal years 1993 through 1995 and the first two quarters of fiscal 1996, a valuation allowance had been recorded to offset the Company's net deferred tax assets, including the possible future benefit from realization of tax operating loss carryforwards. The recording of such valuation allowance was based upon management's determination that realization of the net deferred tax assets was not "more likely than not" (as defined in Statement of Financial Accounting Standards No. 109, "Accounting for Income Taxes"). During the third quarter of 1996, the Company received product acceptance from its initial customer and started profitable operations, at which time the Company fully reversed its previously established deferred tax valuation allowance. The tax benefit of $4.6 million recorded in the third quarter reflects the impact of such reversal. See Note 10 of Notes to Financial Statements. LIQUIDITY AND CAPITAL RESOURCES Since inception, the Company has financed its operations and capital expenditures principally through the sale of Convertible Preferred Stock for proceeds totalling $40.6 million and capital lease financing totalling $4.1 million. At the end of fiscal 1996, the Company's principal source of liquidity was its cash of $22.6 million. In November 1996, the Company established an unsecured $15.0 million bank revolving line of credit. Borrowings under this line bear interest at the bank's prime rate. As of November 30, 1996, there were no borrowings outstanding under the line of credit. The line of credit expires in November 1997 and requires that the Company maintain certain financial ratios and minimum profitability and tangible net worth. See Note 6 of Notes to Financial Statements. Capital equipment expenditures from inception through October 31, 1996 totalled $11.7 million. These expenditures were primarily for test, manufacturing and computer equipment. The Company expects additional capital equipment expenditures to be made during fiscal 1997 to support selling and marketing, manufacturing and product development activities. In addition, since its inception the Company has used $2.4 million for the construction of leasehold improvements and expects to use an additional $5.0 million of capital in the construction of leasehold improvements for its new facility and the conversion to full manufacturing of its current facility during fiscal 1997. The Company believes that the proceeds from the Offerings, combined with its existing cash balance, its line of credit and the cash flows expected from future operations, will be sufficient to meet the Company's capital requirements for at least the next 18 to 24 months. 20 22 BUSINESS OVERVIEW CIENA designs, manufactures and sells DWDM systems for long distance fiberoptic telecommunications networks. CIENA's DWDM solution, the MultiWave 1600 system, alleviates capacity, or bandwidth, constraints in high traffic fiberoptic routes without requiring the installation of new fiber. In addition, the MultiWave 1600 system enables flexible provisioning of additional bandwidth without requiring an upgrade of existing network transmission equipment. The MultiWave 1600 system can increase the carrying capacity of a single optical fiber 16 fold by allowing simultaneous transmission of up to 16 optical channels per fiber. This permits fiber currently carrying signals at transmission speeds of up to 2.5 Gb/s to carry up to 40 Gb/s. CIENA's MultiWave 1600 system includes optical transmission terminals, optical amplifiers and network management software. CIENA's system is designed with an open architecture that allows the MultiWave 1600 system to interoperate with carriers' existing fiberoptic transmission systems having a broad range of transmission speeds and signal formats. The Company believes it is a worldwide market leader in field deployment of open architecture DWDM systems. CIENA's MultiWave 1600 system was introduced into field trials in the long distance network of Sprint in May 1996 and WorldCom in August 1996. The MultiWave 1600 system began carrying live traffic in the Sprint network in October 1996. The Company has a three-year non-exclusive supply agreement with Sprint which expires in December 1998, a supply agreement with WorldCom which, subject to certain conditions, is exclusive through December 1997 and an agreement to supply Teleway with the Company's MultiWave 1600 system. Through October 31, 1996, the Company recorded $54.8 million in revenue, all of which was derived from sales of the MultiWave 1600 system to Sprint. The Company is actively seeking additional customers among other long distance carriers in the worldwide telecommunications market. INDUSTRY BACKGROUND The four largest long distance carriers in the United States, AT&T Corporation ("AT&T"), MCI Communications Inc. ("MCI"), Sprint and WorldCom, have widely deployed fiberoptic cable forming the backbone of their long distance networks. Growth in utilization of long distance networks has increased both the type of traffic -- from voice alone to voice, data and video -- and the volume of traffic carried over these fiberoptic networks. This growth in utilization has been caused by factors such as: - increased use of office automation, distributed computing, electronic mail, facsimile transmission, electronic transaction processing, video conferencing, remote access telecommuting, local and wide area networking and the growing use of the Internet; - widespread deregulation of the telecommunications industry and the consequent increase in competition among, and lowering of prices by, service providers in the long distance market; and - development of high bandwidth, network access technologies, such as cable modems, hybrid fiber coaxial architectures and digital subscriber lines, that permit users to transmit and receive high volumes of information. Increased utilization creates transmission bottlenecks on heavily used routes that were originally designed for significantly less traffic. Although exact statistics are not available, the Company believes that this increase in type and volume of utilization has caused some long distance telecommunications carriers to handle traffic over certain long distance routes at or near the maximum capacity of the existing installed fiber and electronic-based transmission systems currently in use. The growth in demand for, and the resulting strains on, capacity of the fiberoptic telecommunications networks have been coupled with an increasing need for network reliability to support 21 23 mission critical data communications. As end-users become more dependent on around-the-clock network availability, they become less tolerant of service interruptions which can be caused by factors such as equipment failure, fiber cuts or high traffic volume. This demand for greater reliability has led long distance carriers to adopt "ring architecture" in which long distance routes are linked in a ring configuration so that in the event of a fiberoptic cable cut or other equipment failure between two points of the ring, the signal can be immediately redirected through the reverse "protection path" of the ring. The service break associated with a fiber cut or other equipment failure in a network using ring architecture can be restored in approximately 50 milliseconds, which is essentially unnoticeable by the consumer. However, many ring architectures now being deployed demand twice as much fiber capacity (due to the need to maintain a redundant alternative path to serve as a protection path for each fiber in use) as non-ring based architectures. AT&T, Sprint and WorldCom have all announced an intention to implement ring architecture for their networks, which will place greater bandwidth demand on their existing fiberoptic networks. The shortage of bandwidth available in existing fiberoptic networks can be addressed in several ways. One solution is to install additional fiberoptic cable along existing routes or in new fiberoptic routes. However, the installation of additional fiber, and particularly the creation of new fiberoptic routes, is a costly and time-consuming process, involving extensive negotiation and acquisition of necessary rights of way, as well as the actual construction effort. The Company believes that the average cost of creating new underground fiberoptic routes is approximately $43,400 per kilometer ($70,000 per mile). Another solution is to increase the transmission speed of the installed systems. However, this approach is also costly. Existing long distance telecommunications routes generally use TDM fiberoptic transmission terminals at either end of the route to send and receive signals. Opto-electronic signal regenerators ("regenerators") are then placed between terminals along the fiberoptic cables, spaced at regular intervals of 35-50 kilometers (approximately 22 to 31 miles). These regenerators process, amplify and re-time the signal through a process that involves conversion of the optical signal to electronic form and back to optical form. However, terminals and regenerators are "bit-rate specific," meaning upgrade of a route segment to handle higher transmission speeds requires replacement of all terminals and regenerators. A large number of regenerators are needed on a route of significant length, and any upgrade of a route segment using TDM technology would require a significant investment in new equipment as well as significant installation costs. Certain types of existing fiber have been shown to display incompatibility problems with very high speed TDM equipment. "Non-dispersion shifted" fiber constitutes the majority of fiber installed in North America and Europe, while "dispersion shifted" fiber has been popular in Japan. "Reduced dispersion" fiber is a recent development that is beginning to see applications in some new fiber installations. At lower transmission rates, such as 2.5 Gb/s, TDM-based equipment is technically viable for use with these fiber types and widely available commercially. As an upgrade to existing telecommunications links with transmission rates below 2.5 Gb/s, TDM at 2.5 Gb/s can represent an alternative incremental approach to the enhancement of transmission capacity. However, at the 10 Gb/s transmission rate, transmission over non-dispersion shifted fiber can result in significant impairments to and distortion of the signal. CIENA and others have observed that the potential for an alternative technological solution to laying new fiber or upgrading capacity to higher electronic transmission rates exists because the bandwidth intrinsic to existing fiber is vastly underutilized. For example, transmission systems which use TDM and transmit at 2.5 Gb/s use substantially less than one percent of the inherent bandwidth of the fiber currently deployed in United States fiberoptic networks. An optical multiplexing technology called wavelength division multiplexing ("WDM") has long been recognized for its potential to better utilize fiber bandwidth by enabling the simultaneous transmission of multiple optical signals on discrete channels on a single fiber. Until recently, however, technological barriers have limited exploitation of the potential of WDM as a commercially viable solution. DWDM is an 22 24 extension of WDM technology and refers to the simultaneous transmission of more than four channels on a single fiber. THE CIENA SOLUTION CIENA has deployed a DWDM system that enhances the transmission capacity of a single optical fiber 16 fold, without requiring significant modification or upgrade to transmission equipment. The MultiWave 1600 system includes terminals, optical amplifiers and network management software that enable simultaneous transmission of up to 16 optical channels on a single fiber at rates of up to 2.5 Gb/s per channel. The MultiWave 1600 system permits the transmission of optical signals over routes of up to 600 kilometers (372 miles) without opto-electronic regeneration. CIENA's implementation of DWDM technology incorporates the following features: - OPEN ARCHITECTURE SYSTEM. CIENA's system is designed with an open architecture that allows the MultiWave 1600 system to interoperate with carriers' existing fiberoptic transmission systems having a broad range of transmission speeds and signal formats. This approach is distinguished from a closed architecture system design pursued by companies that manufacture other telecommunications equipment and may seek to preserve the market for their network equipment. - MODULAR DESIGN. The MultiWave 1600 system design is modular and allows capacity-specific configurations and the ability to add additional capacity through a modular upgrade. This enables a customer to select the number of channels to use in a particular fiber and preserves the customer's ability to respond quickly to increased demand for capacity without significant additional equipment purchases. - TACTICAL IMPLEMENTATION. CIENA's MultiWave 1600 system can be tactically implemented on a route-by-route basis, providing relief on capacity constrained routes without mandating a network-wide architectural or transmission equipment change. In the context of new network construction, the Company believes that its ability to permit 40 Gb/s capacity per fiber, together with the elimination of multiple regenerators, make the MultiWave 1600 system cost-efficient. - SCALEABLE AMPLIFIERS. The Company's optical amplifiers, when installed to accommodate 16 channels, do not need to be changed as channels are added or as transmission speeds are increased to up to 2.5 Gb/s. Unlike a TDM upgrade solution which involves replacement of all transmission equipment along a fiber route, a channel upgrade of a CIENA MultiWave 1600 system involves no replacement of existing transmission equipment until all 16 channels are in service. Similarly, increases in transmission rates up to a maximum of 2.5 Gb/s do not require replacement of or modification to the optical amplifiers. - MANAGEMENT SOFTWARE. CIENA's MultiWave 1600 system includes network management software enabling customers to receive early warnings of network problems and to manage and monitor network performance. The Company's commitment to providing standards compliant network management interfaces at all levels, from individual network elements to the element management system, affords rapid integration into existing telecommunication management operations. The Company provides standards compliant network management systems based upon Simple Network Management Protocol (SNMP), Transmission Control Protocol/Internet Protocol (TCP/IP) and the International Telecommunications Union (ITU) Telecommunications Management Network (TMN) standards. - FIBER COMPATIBILITY. The CIENA MultiWave 1600 system is compatible with dispersion shifted, reduced dispersion and non-dispersion shifted fiber. Non-dispersion shifted fiber constitutes the majority of fiber installed in North America and Europe. CIENA's MultiWave 1600 system is based upon the use of three core enabling technologies that assist in overcoming many of the constraints that limited commercial introduction of WDM technology: Erbium-doped fiber amplifiers enabling the direct amplification of optical signals without the use of electronic regenerators; in-fiber Bragg gratings enabling precise filtering of multiple optical signals 23 25 in a single fiber; and network management software developed by the Company permitting a customer to manage effectively the status and functions of the CIENA MultiWave 1600 system in conjunction with the network operator's management of other parts of its network. CIENA'S STRATEGY The Company's strategy is to maintain and build upon its market leadership in the deployment of DWDM systems. Important elements of the Company's strategy include: - MAINTAIN LEADERSHIP IN DEPLOYMENT OF DWDM IN LONG DISTANCE NETWORKS. The Company believes that the technological, operational and cost benefits of the Company's DWDM systems create competitive advantages for long distance telecommunications carriers worldwide. The Company also believes that achieving early widespread operational deployment of its systems in a particular carrier's network will provide CIENA significant competitive advantages with respect to additional DWDM deployments and channel upgrades within that network and will enhance its marketing to other carriers as a field proven supplier. The Company therefore intends to continue aggressively pursuing DWDM deployment opportunities among long distance carriers in the domestic and foreign long distance markets. The Company will focus its MultiWave product development efforts on expanding the current 16 channel capacity of the MultiWave 1600 system to 40 channels while adding operational features designed to make MultiWave products as attractive and flexible as possible to long distance telecommunications carriers. - CONTINUE TO EMPHASIZE TECHNICAL SUPPORT AND CUSTOMER SERVICE. The Company markets a technically advanced system to sophisticated customers. The nature of the Company's system and market require a high level of technical support and customer service. The Company expects to have full-time customer support offices in Kansas City, Kansas (to support Sprint), Tulsa, Oklahoma (to support WorldCom) and other selected locations where it develops significant customer relationships, to provide on-going support to its customers. - CONTINUE TO DEVELOP WORLD CLASS MANUFACTURING CAPABILITY. The Company's system serves a mission critical role in its customers' networks. Quality assurance and manufacturing excellence are necessary for the Company to achieve success. CIENA believes it has developed and will continue to enhance a world class manufacturing capability. The Company invested $5.9 million in capital improvements in fiscal 1996 and hired 125 employees in that year to increase manufacturing capacity and efficiency and improve manufacturing quality. The Company is working actively to achieve ISO 9001 certification. - EXPAND SALES AND MARKETING EFFORTS. The nature of the target customer base for MultiWave 1600 systems requires a focused sales effort on a customer-by-customer basis. The Company will continue to increase its sales and marketing efforts by focusing on the worldwide market of long distance carriers. In fiscal 1996, the Company increased its sales and marketing force by 12 persons. The Company will continue to strengthen its marketing programs and increase its international presence through both direct sales and international distributors. - LEVERAGE CORE COMPETENCIES IN FIBEROPTIC COMMUNICATIONS. The Company expects to leverage the core competencies it has developed in the design, development, manufacturing and commercial introduction of the MultiWave 1600 system by exploring other areas in the telecommunications market where these competencies can be used to solve related problems. This may take the form of new product development or may involve strategic alliances or acquisitions. 24 26 NETWORK ARCHITECTURE A CIENA MultiWave 1600 system is a combination of equipment and software that is installed on a particular long distance route segment. A MultiWave 1600 system consists of one MultiWave terminal on each end of the route segment, one or more MultiWave optical amplifiers along the route (depending on route length) and CIENA's WaveWatcher network management software. The diagram below depicts an operating configuration of a deployed MultiWave 1600 system in a four-fiber ring architecture network configuration: [This diagram shows an outline of the United States with a four-fiber ring architecture network configuration. Depicted within the four-fiber ring architecture is a MultiWave 1600 system.] The MultiWave terminal at one end of the route multiplexes the customer's optical signals into as many as 16 discrete optical channels and transmits those channels simultaneously on the outbound fiber of the fiber pair. A MultiWave terminal at the other end of the route demultiplexes the inbound multichannel signal into 16 individual signals that are directed to the customer's receivers. Optical amplifiers placed along the route provide optical amplification of the composite multichannel signal over long route lengths. The Company's WaveWatcher software provides continuous network management capability by monitoring system functions. The diagram below compares (i) traditional transmission equipment configuration for a high traffic (16 signal) long distance route of 600 kilometers (372 miles), using TDM transmission terminals and regenerators with (ii) the same high traffic (16 signal) long distance route configured with a MultiWave 1600 system. [This diagram consists of two figures. The first figure shows a traditional TDM route configuration with fiberoptic transmission terminals at both ends of a 16-fiber pair route with 272 regenerators. The second figures shows the same route with the MultiWave 1600 system.] In the TDM configuration above, 16 fiber pairs, and a total of 272 regenerators, are needed to transport 16 channels over the route. Each regenerator converts the channels from optical to electrical and back to optical format at 35-50 kilometer (22 to 31 mile) intervals. In order to upgrade the transmission capacity of the typical TDM network route, as shown forth above, using traditional TDM technology, all the fiberoptic transmission terminals and all 272 regenerators would need to be replaced. This process entails significant equipment costs, requires rerouting of transmissions and can be time-consuming and, potentially, an operational bottleneck. While the TDM configuration above is typical, the actual number of regenerators may be less than depicted above. By contrast, as shown above, the same high traffic (16 signal) long-distance route can be configured with a MultiWave 1600 system. The 272 regenerators are replaced with four MultiWave optical amplifiers and only one fiber pair is required for transmission of 16 signals. As a result, 15 of the 16 fiber pairs that were previously used are freed for future use. The maintenance costs associated with the 272 regenerators are eliminated and replaced by the lower maintenance costs of four optical amplifiers. Because each regenerator must be housed in a weather-protected, environmentally controlled shelter, elimination of regenerator sites may also significantly lower operational costs. Increasing the availability of a number of fiber pairs is especially significant to carriers that have implemented or are planning to implement ring architectures and those providing leased transmission capacity to other operators. THE MULTIWAVE 1600 SYSTEM A MultiWave 1600 system is installed in a discrete route segment defined at each end by the presence of the customer's fiberoptic transmission terminals. The MultiWave 1600 system features 25 27 an open architecture which interoperates with a broad range of models of fiberoptic transmission terminals. The MultiWave 1600 system can be flexibly configured based on the customer's capacity needs with up to 16 channels, and the initial channel configuration, if less than 16 channels, can be supplemented whenever additional capacity is needed. The modular design of the MultiWave 1600 system allows the network operator to add capacity without interrupting existing MultiWave traffic. MULTIWAVE TERMINAL. The CIENA MultiWave terminal is a modular DWDM terminal which can multiplex and amplify signals from transmitters into 16 discrete optical channels for transmission over a pair of fibers to the other MultiWave terminal and demultiplex the received multichannel signal into 16 individual signals. The MultiWave terminal functions in the same manner over a broad range of transmission speeds, up to approximately 2.5 Gb/s per channel, and operates without material modifications to existing fiberoptic transmission systems. Each MultiWave terminal consists of up to two channel shelves (up to eight channels per shelf) and a common equipment shelf. The MultiWave terminal can transport over total route lengths of up to 600 kilometers (372 miles) at up to 2.5 Gb/s per channel without regeneration or impairment of the signal. MULTIWAVE OPTICAL AMPLIFIER. The CIENA MultiWave optical amplifier is a modular Erbium-doped fiber amplifier that provides direct composite optical amplification of the 16 optical channels carried by the MultiWave 1600 system. A single MultiWave optical amplifier shelf is capable of amplifying the system's entire 40 Gb/s capacity (16 channels times approximately 2.5 Gb/s per channel). CIENA's MultiWave optical amplifiers take the place of the customer's existing regenerators on routes of up to 600 kilometers (372 miles), and can be spaced as much as 120 kilometers (74 miles) apart. WAVEWATCHER NETWORK MANAGEMENT SYSTEM. WaveWatcher is the MultiWave 1600 system's integrated network management software package. The network element manager uses a separate out-of-band optical service channel to communicate network management information and provides a single view of multiple CIENA systems through graphical user interfaces and supported operating system interfaces. WaveWatcher has been designed to adhere to evolving open system standards for network management software and operates on a UNIX platform. WaveWatcher provides fault, performance, security and configuration management of optical networking systems. The Company is also introducing an optical add/drop multiplexer to enable carriers to reroute traffic to different geographic areas without requiring extensive termination equipment. A network operator may optically remove up to four channels from the composite signal at a point along a fiber route where the optical add/drop multiplexer is installed. The installation of an additional optical add/drop multiplexer at a different point along that route would enable the network operator to reuse those channels. The optical add/drop multiplexer also will provide optical amplification for up to 16 channels. A typical MultiWave 1600 system ranges in price from $500,000 to $1,500,000, depending on such factors as customer needs for number of channels, route length (which affects the number of optical amplifiers required), network management software configuration and other negotiated terms and conditions. As required, systems initially configured for less than 16 channels can be upgraded to carry up to 16 channels at additional cost. PRODUCT DEVELOPMENT The Company expects the primary focus of its product development efforts will be in the further enhancement and refinement of the MultiWave 1600 system. The Company will focus its product development efforts on expanding the current 16 channel capacity of the MultiWave 1600 system to 40 channels while adding operational features designed to make the Company's products attractive to a wide range of network operators. The Company has developed core competencies in DWDM technology through the design, development, manufacturing and commercial introduction of the MultiWave 1600 system. In the 26 28 future, the Company intends to migrate its core competencies in this area to other segments of the telecommunications network. This migration may take the form of new product development or may involve strategic alliances or acquisitions. As of October 31, 1996, there were 38 persons working in the Company's research and development area. The Company's research and development expenditures were $1.3 million, $6.4 million and $8.9 million for fiscal 1994, 1995 and 1996, respectively. CUSTOMERS SPRINT RELATIONSHIP In December 1995, the Company entered into a three-year supply agreement with Sprint, with the option for Sprint to extend the term of the agreement for an additional year. Prices for all equipment purchased by Sprint under the terms of the supply agreement are fixed for the initial three-year term but the prices charged to Sprint for any deliverable under the supply agreement will not at any time be higher than the Company's final net price to any "similarly situated customer". The supply agreement does not obligate Sprint to make any minimum purchases from the Company. The agreement requires that the Company set up and maintain, at the Company's expense, certain test facilities for a period of 10 years. The Company is obligated to provide software and equipment support until December 2005 and must maintain two years of backwards compatibility for any enhancements or upgrades to the software. The Company also warrants each deliverable provided by the Company for 60 months from the date of delivery, with Sprint having the right until December 2005 to purchase an unlimited number of one-year extensions of any or all warranties. Upgrades are provided at no cost to Sprint during the warranty or extended warranty periods. The supply agreement contains penalties for failure to respond to various types of system failures in a timely manner. The supply agreement with Sprint also provides Sprint with a license to use, modify and enhance the Company's source code under certain conditions. WORLDCOM RELATIONSHIP In September 1996, the Company entered into a supply agreement with WorldCom. Pursuant to the terms of the supply agreement, upon the successful completion of the field test, the Company will be the exclusive supplier of DWDM systems for WorldCom through December 1997. The agreement does not require a minimum purchase commitment; if WorldCom, however, does not purchase a certain minimum amount of equipment, all prices for equipment purchased under the agreement increase. WorldCom may terminate all or any part of an outstanding purchase order upon the payment of a termination fee. The Company has granted to WorldCom, pursuant to the supply agreement, a license to use certain software. The Company has also granted WorldCom the option to purchase the source code for certain software at any time during the term of the agreement for a one-time payment. If WorldCom exercises this option, the Company has no further obligation to provide support or maintenance services or to provide upgrades or enhancements with respect to this software. Under product and pricing attachments currently in effect, the Company provides WorldCom with software upgrades at no charge for a period of 10 years from installation and provides a five-year warranty for products. TELEWAY RELATIONSHIP The Company has entered into a two-year agreement with NISSHO Electronics Corporation ("NISSHO") to act as a distributor of the Company's MultiWave 1600 system in Japan. Through NISSHO, the Company has shipped a MultiWave 1600 system to Teleway. 27 29 OTHER POTENTIAL CUSTOMER RELATIONSHIPS The Company is actively working to develop customer relationships with long distance carriers worldwide. The Company has contacted other long distance carriers and is responding to requests for proposals as well as engaging in direct sales efforts. Under the Telecommunications Act of 1996, regional Bell operating companies ("RBOCs") are newly eligible to enter the long distance market once they have met certain requirements for opening their local markets to competition. The Company anticipates that one or more of the RBOCs will move into the long distance market, although the timing of that move is uncertain, and the question of how such a move will be implemented is unclear -- e.g., through the establishment of owned network facilities, through the purchase of long distance capacity from other long distance carriers, or through some combination of the two. In the deregulated market, utility companies are also known to be exploring the use of their existing rights of way to develop fiberoptic-based telecommunications networks, although it is not possible to predict the pace or scope of their efforts. Internationally, the market for DWDM systems is still developing. The deregulation and competition which have characterized the United States long distance market are much less pronounced in most international markets, and the data communications applications which fuel the demand for high bandwidth transmission systems in the United States are not as widely used in international markets. The Company intends to concentrate its international sales and marketing efforts in countries or regions where there is competition among two or more long distance carriers, where there are significant bandwidth constraints and where there is significant potential for near term growth in telecommunications services. SALES AND MARKETING The Company has organized its resources for the separate but coordinated approach to United States customers and international customers. In the United States market, a sales team, comprised of an account manager, systems engineers and technical support and training personnel, is assigned responsibility for each customer account, and for the coordination and pursuit of sales contacts. In the international market, the Company currently pursues prospective customers through direct sales efforts, as well as through distributors, independent marketing representatives and independent sales consultants. The Company has distributor or marketing representative arrangements covering Austria, Germany, Italy and Switzerland in Europe, and the Republic of Korea and Japan in Asia. The Company has additional representative support in the U.K., Belgium and Brazil. The Company intends to establish a direct sales presence in Europe and in Asia over the next 12 to 18 months. The Company's MultiWave 1600 systems require a relatively large investment, and the Company's target customers in the long distance telecommunications market -- where network capacity and reliability are critical -- are highly demanding and technically sophisticated. There are only a small number of such customers in any country or geographic market. Also, every network operator has unique configuration requirements which impact the integration of DWDM systems with existing transmission equipment. The convergence of these factors leads to a very long sales cycle for the MultiWave 1600 system, often more than a year between initial introduction to the Company and commitment to purchase, and has further led CIENA to pursue sales efforts on a focused, customer-by-customer basis. In support of its worldwide selling efforts, the Company conducts marketing programs intended to position and promote its products within the telecommunications industry. Marketing personnel coordinate the Company's participation in trade shows and conduct media relations activities with trade and general business publications. 28 30 COMPETITION The market for increased bandwidth is highly competitive, and the Company expects the level of competition to increase in the future. In addition, competition in the telecommunications equipment industry generally is intense, particularly in that portion of the industry devoted to delivering higher and more cost effective bandwidth throughout the telecommunications network. However, the Company believes that its position as a leading supplier of open architecture DWDM systems and the field-tested design and technology of its product give it a current competitive advantage. The competition faced by the Company is dominated by a small number of very large, usually multinational, vertically integrated companies, each of which has substantially greater financial, technical and marketing resources, and greater manufacturing capacity as well as more established customer relationships with long distance carriers than the Company. Included among the Company's competitors are Lucent, Nortel, Alcatel, NEC and Pirelli. Each of the Company's major competitors are believed to be in various stages of development, introduction or deployment of DWDM products directly competitive with the Company's MultiWave system. Pirelli, in particular, is known to have deployed open architecture WDM equipment and has announced the introduction of a 32-channel DWDM system. Lucent has an especially prominent role in the market because of its historical affiliation with AT&T. Lucent has announced it is supplying closed architecture DWDM system equipment to AT&T, and has announced an intention to introduce in the near future an open architecture DWDM system. Although Lucent's prior affiliation with AT&T may have inhibited its relationships as a supplier to other carriers, the spin-off of Lucent into a separate company may make it more attractive to potential customers as a supplier. In addition to DWDM suppliers, traditional TDM-based transmission equipment suppliers compete with the Company in the market for transmission capacity. Lucent, Alcatel, Nortel, Fujitsu and NEC are already providers of a full complement of such equipment. These and other competitors have introduced or are expected to introduce equipment which will offer 10 Gb/s transmission capability, and MCI has recently announced limited deployment of such equipment. The viability of widescale deployment of 10 Gb/s TDM based equipment has yet to be demonstrated. Because of the transmission rate employed, the 10 Gb/s TDM equipment requires digital multiplexing circuits operating at microwave frequencies, which can lead to instability. This can complicate reproducibility, which may in turn result in delays in introduction and higher manufacturing costs. More significantly, at the 10 Gb/s transmission rate, dispersion distortion effects in the fiber can result in significant impairments and limitations, particularly in transmission over non-dispersion shifted fiber, which comprises most of the installed fiber in current long distance networks in the United States. However, at lower rates, such as 2.5 Gb/s, TDM-based equipment is technically viable and widely available commercially, and, as an upgrade to existing lower transmission rate telecommunications links, can represent an alternative incremental approach to the enhancement of transmission capacity. Additionally, while the Company believes the open architecture of its MultiWave 1600 system is attractive to some customers, certain of the Company's competitors are able to offer more extensive TDM-based product lines under closed architectures which may provide perceived network-wide cost and operating efficiencies not available from the Company. For example, Lucent, Alcatel, Nortel and NEC are already providers of a full complement of TDM terminals, switches and regenerators, and thereby seek to position themselves as vertically integrated, "one-stop shopping" solution providers to potential customers. The Company expects competition in general to intensify substantially over the next few quarters. The Company believes that competition is based on varying combinations of price, manufacturing capacity, timely delivery, system reliability and service commitment, installed customer base, as well as on the comprehensiveness of the system solution in meeting immediate network needs and foreseeable scaleability requirements. Further, in certain cases, competitors have offered the Company's target customers on an immediate delivery basis, off the shelf TDM transmission equipment at comparatively lower prices, with a promise to upgrade to DWDM or other improved equipment in the future. While the Company is ramping up its 29 31 manufacturing capability as rapidly as it believes prudent, the Company is not currently able to offer MultiWave 1600 system delivery times of less than three to four months. The substantial system integration resources and manufacturing capability of the TDM competitors, in combination with any difference in timeliness of delivery, can be important to long distance network operators for whom a less significant increase in transmission capacity (as opposed to the 16-fold increase available through MultiWave) is acceptable. In addition, as and when these competitors are able to offer DWDM systems in combination with their own terminals, they can be expected to further emphasize the attractiveness of a one-stop shopping solution. MANUFACTURING The Company manufactures the in-fiber Bragg gratings and Erbium-doped fiber amplifiers used in the MultiWave 1600 system, and conducts all optical assembly, final assembly and final component, module and system test functions, at its manufacturing facility in Savage, Maryland. The Company has invested significantly in automated production capabilities and manufacturing process improvements and expects to further enhance its manufacturing process with additional production process control systems. However, certain critical functions, including aspects of fiber splicing, require a highly skilled manual work force, and the Company puts significant efforts into training and maintaining the quality of its manufacturing work force. The Company is also currently working towards obtaining an ISO 9001 certification, which it believes will be a further competitive strength. Electronic board assemblies are currently subcontracted to third parties to enable the Company to concentrate on its core manufacturing competencies in gratings production and optical assembly capabilities. The Company has not experienced any significant delays or material unanticipated costs resulting from the use of subcontractors; however, such a strategy involves certain risks, including the potential absence of adequate capacity, the unavailability of or interruptions in access to certain process technologies, and reduced control over delivery schedules, manufacturing yields, quality and costs. In the event that any significant subcontractor were to become unable or unwilling to continue to manufacture and/or test the Company's assemblies in required volumes, the Company would have to identify and qualify acceptable replacements. This qualification process could also be lengthy and no assurance can be given that any additional sources would become available to the Company on a timely basis. A delay or reduction in component shipments, or a delay or increase in costs in the assembly and testing of products by third party subcontractors, could materially and adversely affect the Company's business, financial condition and results of operations. The Company's MultiWave 1600 system utilizes in excess of 600 parts, many of which are customized for the Company. Component suppliers in the specialized, high technology end of the optical communications industry are generally not as plentiful or, in some cases, as reliable, as component suppliers in more mature industries. Certain key optical and electronic components used in the Company's MultiWave 1600 system are currently available only from sole sources. The Company has from time to time experienced minor delays in the receipt of these components, and any future difficulty in obtaining sufficient and timely delivery of them could result in delays or reductions in product shipments which, in turn, could have a material adverse effect on the Company's business, financial condition and results of operations. While alternative suppliers have been identified for certain other key optical and electronic components, those alternative sources have not been qualified. The time and expense involved in qualifying each additional source are significant. Accordingly, the Company will for the near term continue to be dependent on sole and single source suppliers of certain key components. See "Risk Factors -- Dependence on Suppliers" and "-- Competitors as Suppliers". PATENTS AND OTHER INTELLECTUAL PROPERTY RIGHTS The Company has licensed certain key enabling technologies with respect to the production of in-fiber Bragg gratings, utilized publicly available technology associated with Erbium-doped fiber 30 32 amplifiers, and applied its design, engineering and manufacturing skills to develop its MultiWave 1600 system. The Company also licenses from third parties certain software components for its network management software. The Company has applied for trademark registration for Ciena, MultiWave and WaveWatcher. Opposition has been filed with the United States Patent and Trademark Office with respect to the Company's registration of WaveWatcher. The Company also relies on contractual rights, trade secrets and copyrights to establish and protect its proprietary rights in its products. The Company intends to enforce vigorously its intellectual property rights if infringement or misappropriation occurs. However, the Company does not expect its proprietary rights in its technology will prevent competitors from developing technologies and equipment functionally similar to the Company's. The Company's practice is to require its employees and consultants to execute non-disclosure and proprietary rights agreements upon commencement of employment or consulting arrangements with the Company. These agreements acknowledge the Company's exclusive ownership of all intellectual property developed by the individual during the course of his work with the Company and require that all proprietary information disclosed to the individual will remain confidential. As of December 4, 1996, the Company had received seven United States patents, had received notice of allowance of two more, and had 16 pending patent applications. The issued patents relate to (i) an optical monitoring channel for WDM systems capable of surviving failure of an optical amplifier, (ii) an in-fiber Bragg grating system for optical cable television systems that allows the network operator to remove and insert different optical frequencies and switch video signals on demand, (iii) a WDM optical communication system with remodulators to carry multiple optical signals of different wavelengths simultaneously, (iv) a WDM system that can be expanded with additional optical signals, (v) an optical system which uses optical amplifiers with flattened gain curves, (vi) a method for removing and inserting optical carriers in a WDM system and (vii) an optical system with tunable in-fiber gratings. Allowed patent applications relate to other aspects of in-fiber Bragg gratings technology and other aspects of WDM system design. In addition, the Company holds a non-exclusive license from General Instrument Corporation of Delaware for a portfolio of 32 United States and foreign patents relating to optical communications, primarily for video-on-demand applications. See "Risk Factors -- Proprietary Rights". EMPLOYEES As of October 31, 1996, the Company employed 225 persons, of whom 38 were primarily engaged in research and development activities, 135 in manufacturing, 20 in sales, marketing, customer support and related activities and 32 in administration. None of the Company's employees are currently represented by a labor union. The Company considers its relations with its employees to be good. FACILITIES The Company's principal executive offices, manufacturing and research and development facilities are all located in Savage, Maryland and consist of approximately 50,500 square feet under a lease that will expire in December 2001, absent exercise of a renewal option for an additional five years. The base rent averages approximately $35,775 per month for the first six years. The Company signed a lease in October 1996 for a facility approximately 10 miles from Savage, near the Baltimore/Washington International Airport ("BWI"). This facility consists of approximately 96,000 square feet, and is expected to be suitable for occupancy by March 1997. Base rent is approximately $102,000 per month, with annual rate increases each of the ten years of the initial lease term, with a final year rate of approximately $126,000 per month. The Company intends to convert substantially all of its current Savage, Maryland, facility into a manufacturing facility (manufacturing 31 33 currently occupies approximately 19,000 of the 50,500 square feet at the Savage facility), and relocate the corporate, sales and marketing and product development functions to the BWI facility. LEGAL PROCEEDINGS Kevin Kimberlin and parties controlled by him (the "Kimberlin Parties") are owners of Common Stock, Series A, Series B and Series C Preferred Stock and certain warrants to purchase Series B Preferred Stock. On November 20, 1996, the Kimberlin Parties filed suit in U.S. District Court for the Southern District of New York against the Company, and certain directors of the Company, alleging that the Kimberlin Parties were entitled to purchase additional shares of Series C Preferred Stock at the time of the closing of the Series C Preferred Stock financing, but were denied that opportunity by the defendants. The lawsuit alleges that certain rights of first refusal existing under the Series B Preferred Stock Purchase Agreement entitled the Kimberlin Parties to purchase more shares of Series C Preferred Stock than were in fact purchased by them at the time of the closing of the Series C financing in December 1995. The lawsuit claims breach of contract, breach of fiduciary duty and violation of Securities and Exchange Commission Rule 10b-5 by the defendants. The Kimberlin Parties seek to recover unspecified actual and punitive damages. The number of shares to be purchased by each party to the Series C Preferred Stock financing was communicated in writing to the Kimberlin Parties in December 1995 prior to the Series C closing. Further, as permitted under the Series B Preferred Stock Purchase Agreement, the Series C Preferred Stock Purchase Agreement expressly stated that all rights of first refusal referred to in the lawsuit were waived. The required number of Series B investors, including the Kimberlin Parties, signed the Series C Preferred Stock Purchase Agreement containing that waiver. In July 1996, the Kimberlin Parties reaffirmed to the Company in writing that their beneficial ownership of shares did not include any shares which they have subsequently claimed in the lawsuit they were entitled to purchase. The Company believes that the Kimberlin Parties' claims, brought as the Offerings were being prepared, are without merit and intends to defend itself vigorously. The Company is not currently a party to any other legal proceedings. 32 34 MANAGEMENT DIRECTORS AND EXECUTIVE OFFICERS The table below sets forth certain information concerning each of the directors and executive officers of the Company:

Actual gains, if any, on stock option exercises are dependent on the future performance of the Common Stock, overall market conditions and the option holders' continued employment through the vesting period. This table does not take into account any appreciation in the price of the Common Stock from the date of grant to date. Assuming the fair market value of the Common Stock at the date of grant was the assumed initial public offering price of $18.00, the potential realizable value of these options (a) at a 5% assumed annual rate of stock price appreciation would be $23,643,000 for Dr. Nettles, $8,444,000 for Mr. Chaddick, $8,444,000 for Mr. Huang and $1,959,000 for Mr. Chinnici and (b) at a 10% assumed annual rate of stock price appreciation would be $38,839,000 for Dr. Nettles, $13,871,000 for Mr. Chaddick, $13,871,000 for Mr. Huang and $3,218,000 for Mr. Chinnici. AGGREGATED OPTION EXERCISES IN LAST FISCAL AND FISCAL YEAR-END OPTION VALUES The following table provides the specified information concerning unexercised options held as of October 31, 1996 by the Named Executive Officers:

- --------------- (1) All options are immediately exercisable at the date of grant, but shares purchased upon exercise of options are subject to repurchase by the Company based upon a scheduled vesting period. None of the shares underlying options held by Dr. Nettles are vested and 562,500, 578,125 and 113,540 of the shares underlying options held by Messrs. Chaddick, Huang and Chinnici, respectively, are vested. (2) Calculated on the basis of the fair market value of the underlying securities as of October 31, 1996 of $15.94 per share, as determined by the Company's Board of Directors, less the aggregate exercise price. The value of vested in-the-money options held by Dr. Nettles is zero and the value of vested in-the-money options for Messrs. Chaddick, Huang and Chinnici is $8,954,000, $9,203,000 and $1,807,000, respectively. No options to purchase the Company's Common Stock were exercised during the fiscal year ended October 31, 1996 by the Named Executive Officers. No compensation intended to serve as incentive for performance to occur over a period longer than one fiscal year was paid pursuant to a long-term incentive plan during the last fiscal year to any of the Named Executive Officers. EMPLOYMENT AGREEMENTS In April 1994, the Company entered into employment agreements with each of Dr. Huber and Dr. Nettles. The employment agreements specify that Dr. Huber and Dr. Nettles are employees at will. In the event that either of them is terminated for cause, as defined in the employment agreements, he will receive a severance payment equal to his monthly base salary until the earlier of the expiration of six months or the commencement of employment with a person or entity other than the Company. 38 40 MANAGEMENT INCENTIVE COMPENSATION PLAN The Company has established a management incentive compensation plan (the "Incentive Plan") pursuant to which management and non-management employees are eligible to earn up to certain percentages of their base salary as additional compensation, based upon the achievement of quarterly and annual objectives. Under the Incentive Plan, the Chief Executive Officer of the Company may earn up to 50% of his base salary, and Vice Presidents generally may earn up to 35% of their base salaries, as additional compensation upon the achievement of certain Company-wide objectives. Department directors and key managers are eligible to earn up to 15% of their base salaries in additional compensation based on the achievement of objectives which are specific to their functional department. Managers and all other salaried employees are eligible to earn up to 7.5% of their base salaries in additional compensation based on the achievement of objectives which are specific to their functional department. The quarterly objectives are determined on a quarter by quarter basis by the Board of Directors in consultation with management, and address a wide variety of activities with all functional areas of the Company based on the evolving needs of the Company. Bonuses are payable quarterly and at year-end under the Incentive Plan. In addition to amounts paid under the Incentive Plan during fiscal year 1996, the Company paid additional bonuses to all employees in that year. STOCK PLANS AMENDED AND RESTATED 1994 STOCK OPTION PLAN A total of 20,050,000 shares of Common Stock are reserved for issuance under the Company's Amended and Restated 1994 Stock Option Plan (the "Option Plan"). At October 31, 1996, 259,345 shares of Common Stock subject to repurchase by the Company had been issued upon exercise of options, 364,150 shares of Common Stock not subject to repurchase had been issued upon exercise of options and 10,957,960 shares were subject to outstanding options at a weighted average exercise price of $.96. Options may be granted to employees (including officers), consultants, advisors and directors, although only employees and directors and officers who are also employees may receive "incentive stock options" intended to qualify for certain tax treatment. The exercise price of nonqualified stock options must equal at least 85% of the fair market value of the Common Stock as determined by the Board of Directors, and in the case of incentive stock options must be no less than the fair market value of the Common Stock as determined by the Board of Directors. These options are immediately exercisable at the date of grant, but shares purchased upon exercise of options are subject to repurchase by the Company based upon a scheduled vesting period. Generally, shares underlying options vest over four years and options must be exercised within ten years. The Option Plan provides for accelerated vesting in the event of a change of control of the Company, provided the subject options have been outstanding for at least 335 days. Furthermore, in the event of a change in control, the surviving or acquiring company shall either assume the Company's rights and obligations under outstanding stock option agreements or substitute options for the acquiring corporation's stock for the outstanding options. 1996 OUTSIDE DIRECTORS STOCK OPTION PLAN A total of 750,000 shares of Common Stock have been reserved for issuance under the 1996 Outside Directors Stock Option Plan (the "Directors Plan"). As of October 31, 1996, options to purchase 75,000 shares have been granted under the Directors Plan. The Directors Plan provides for the automatic granting of nonqualified stock options to Directors of the Company who are not employees of the Company (the "Outside Directors"). Under the Directors Plan, each current Outside Director will automatically be granted an option to purchase 25,000 shares of Common Stock on the date of each annual meeting of stockholders after the close of the Offerings, provided that the Outside Director continues to serve in such capacity. Additionally, each new Outside Director will automatically be granted an option to purchase 75,000 shares of Common Stock upon assuming the office of Director. The exercise price of the options in all cases will be equal to the fair 39 41 market value of the Common Stock on the date of grant. Initial grants vest over a period of three years and annual grants vest in full on the first anniversary of the date of grant. Options generally must be exercised within ten years. COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION Dr. Bayless, Mr. Cash and Mr. Zak served during the fiscal year ended October 31, 1996 as members of the Compensation Committee of the Board of Directors. Dr. Bayless is an affiliate of Sevin Rosen Bayless Management Co., Sevin Rosen Fund IV L.P. and Sevin Rosen Fund V L.P. (collectively, the "Sevin Rosen Entities"), Mr. Cash is a general partner of InterWest Management Partners V, the general partner of InterWest Partners V, L.P., and of InterWest Investors V, L.P. (collectively, "InterWest"), and Mr. Zak is a general partner of the general partner of Charles River Partnership VII ("Charles River"). Although each of Sevin Rosen, InterWest and Charles River is a stockholder of the Company none of Mr. Cash, Mr. Zak or Dr. Bayless were at any time during the fiscal year ended October 31, 1996, or at any other time, an officer or employee of the Company. No member of the Compensation Committee of the Company serves as a member of the board of directors or compensation committee of any entity that has one or more executive officers serving as a member of the Company's Board of Directors or Compensation Committee. Mr. Cash is not a current member of the Compensation Committee. See "Certain Transactions". LIMITATION OF LIABILITY AND INDEMNIFICATION The Company's Certificate of Incorporation provides that a Director of the Company shall not be personally liable for monetary damages to the Company or its stockholders for a breach of fiduciary duty as a Director, except for liability as a result of (i) a breach of the Director's duty of loyalty to the Company or its stockholders, (ii) acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) an act related to the unlawful stock repurchase or payment of a dividend under Section 174 of Delaware General Corporation Law and (iv) transactions from which the Director derived an improper personal benefit. Such limitation of liability does not affect the availability of equitable remedies such as injunctive relief or rescission. The Company's Certificate of Incorporation also authorizes the Company to indemnify its officers, Directors and other agents, to the full extent permitted under the Delaware General Corporation Law. The Company has entered into separate indemnification agreements with its directors and certain officers which may, in some cases, provide broader indemnification protection than the specific indemnification provisions contained in the Delaware General Corporation Law. The indemnification agreements require the Company, among other things, to indemnify such officers and Directors against certain liabilities that may arise by reason of their status or service as officers or Directors (other than liabilities arising from willful misconduct of a culpable nature), and to advance their expenses incurred as a result of any proceeding against them as to which they could be indemnified. In addition, these agreements extend similar indemnification arrangements to stockholders whose representatives serve as directors of the Company. At present, except for the Kimberlin litigation referred to above under "Business -- Legal Proceedings," there is no pending litigation or proceeding involving a Director, officer, employee or agent of the Company where indemnification will be required or permitted. The Company is not aware of any threatened litigation or proceeding which may result in a claim for such indemnification. The Company expects to provide indemnification to its Directors named in the Kimberlin litigation. CERTAIN TRANSACTIONS STOCK SALES In April 1994, the Company issued and sold shares of Series A Preferred Stock at a purchase price of $1.00 per share, in December 1994, the Company issued and sold shares of Series B 40 42 Preferred Stock at a purchase price of $1.50 per share and in December 1995, the Company issued and sold shares of Series C Preferred Stock at a purchase price of $7.00 per share. The shares of Series A, B and C Preferred Stock were initially convertible into one share of Common Stock, subject to adjustment. The Company effected a five-for-one stock split on December 9, 1996, and each share of Series A, B and C Preferred Stock will convert automatically into five shares of Common Stock upon the closing of the Offerings. In connection with these transactions, the Company also issued warrants to purchase Common Stock at an exercise price of $.02 per share. These warrants have been exercised and the shares of Common Stock issued upon exercise of the warrants are reflected in the table below. The purchasers of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Common Stock included, among others, the following directors, executive officers and holders of more than 5% of the Common Stock:

(8) The shares beneficially owned by Kevin Kimberlin include shares of Kevin Kimberlin Partners L.P. and Spencer Trask Holdings. In April 1994, the Company sold 3,500,000 shares of Common Stock to Dr. Nettles at a purchase price of $.02 per share pursuant to a Stock Purchase and Stock Restriction Agreement dated April 9, 1994. In connection therewith, Dr. Nettles issued a note to the Company in the amount of $63,000. The note was paid in full in March 1995. Under the agreement, one quarter of the shares vested on the first anniversary date of the agreement and the remaining shares vested monthly at a rate of 1/48th per month. Until the shares are fully vested, they are subject to certain restrictions 42 44 including forfeiture in the event employment is terminated, restrictions on transferability and right of first refusal. As of October 31, 1996, 2,183,335 of the shares were vested under the agreement. The Company believes that all transactions with affiliates described above were made on terms no less favorable to the Company than could have been obtained from unaffiliated third parties. All future transactions, including any loans, between the Company and its officers, directors, principal stockholders and their affiliates will be approved by a majority of the Board of Directors, including a majority of the independent and disinterested Outside Directors, and will continue to be on terms no less favorable to the Company than could be obtained from unaffiliated third parties. LITIGATION SETTLEMENT William K. Woodruff & Company, Inc. ("Woodruff") is participating in the Offerings as one of the representatives of the U.S. Underwriters and the International Underwriters as a result of the settlement of litigation instituted by Woodruff in July 1996 against the Company and certain stockholders of the Company. Under a 1994 agreement with the Company, Woodruff was granted a right of first refusal for retention as an "investment banker" in any transaction for which the Company intended to retain one or more investment bankers, subject to certain qualifications, at a predetermined level of compensation. The litigation brought by Woodruff sought to recover monetary, declaratory and injunctive relief, including injunctive relief compelling the Company to include Woodruff as a "co-manager" of the Company's initial public offering under Woodruff's interpretation of the 1994 agreement. Under the terms of the settlement, the Company has agreed to retain Woodruff as one of the representatives of the underwriters of the Company's initial public offering, granted Woodruff warrants to purchase 75,000 shares at an exercise price of $4.00 per share, made a cash payment to Woodruff of $87,500, and agreed to arrange for Woodruff to obtain a designated portion of the compensation to be paid to the underwriters of the Company's initial public offering. The Company entered into this settlement in order to avoid costly and potentially protracted litigation over the questions of Woodruff's entitlement to compensation for, and to participate as a "co-manager" in connection with, the Company's initial public offering. 43 45 PRINCIPAL STOCKHOLDERS The following table sets forth certain information regarding the beneficial ownership of the Company's Common Stock as of November 30, 1996, and as adjusted to reflect the sale of the shares offered hereby, (i) by each person who is known by the Company to own beneficially more than 5% of the Company's Common Stock, (ii) by each Director and Named Executive Officer, (iii) by all officers and Directors as a group and (iv) by certain other holders.

The following summary of the Company's capital stock does not purport to be complete and is subject to, and qualified in its entirety by, the Certificate of Incorporation and bylaws of the Company that are included as exhibits to the Registration Statement of which this Prospectus forms a part and by the provisions of applicable law. COMMON STOCK As of October 31, 1996, there were 86,507,325 shares of Common Stock outstanding and held of record by 112 stockholders, as adjusted to reflect the conversion of the outstanding shares of Convertible Preferred Stock into Common Stock upon the closing of the Offerings. The holders of Common Stock are entitled to one vote for each share held of record on all matters submitted to a vote of the holders of Common Stock. Subject to preferences applicable to any outstanding preferred stock, holders of Common Stock are entitled to receive ratably such dividends as may be declared by the Board of Directors out of funds legally available therefor. In the event of a liquidation, dissolution or winding up of the Company, the holders of Common Stock are entitled to share ratably in all assets remaining after payment of liabilities and the liquidation preference of any preferred stock. Holders of Common Stock have no preemptive or subscription rights, and there are no redemption or conversion rights with respect to such shares. All outstanding shares of Common Stock are fully paid and non-assessable, and the shares of Common Stock to be issued upon completion of the Offerings will be fully paid and non-assessable. As of October 31, 1996, there were warrants to purchase 675,000 shares of Common Stock outstanding and warrants to purchase 300,000 shares of Convertible Preferred Stock outstanding. The warrants to purchase Convertible Preferred Stock expire unless exercised prior to the closing of the Offerings, and an aggregate of 1,500,000 shares of Common Stock are issuable upon conversion of such Convertible Preferred Stock. UNDESIGNATED PREFERRED STOCK The Board of Directors has the authority, without action by the stockholders, to designate and issue preferred stock in one or more series and to designate the dividend rate, voting rights and other rights, preferences and restrictions of each series any or all of which may be greater than the rights of the Common Stock. It is not possible to state the actual effect of the issuance of any shares of preferred stock upon the rights of holders of the Common Stock until the Board of Directors determines the specific rights of the holders of such preferred stock. However, the effects might include, among other things, restricting dividends on the Common Stock, diluting the voting power of the Common Stock, impairing the liquidation rights of the Common Stock and delaying or preventing a change in control of the Company without further action by the stockholders. The Company has no present plans to issue any shares of preferred stock. REGISTRATION RIGHTS Following the sale of the shares of Common Stock offered hereby, the holders of 74,815,740 shares issuable upon conversion of the outstanding shares of Convertible Preferred Stock or issued or issuable to certain holders of the warrants, and certain shares held by certain founders of the Company and their transferees will have certain rights to register those shares under the Securities Act. These rights are provided under the terms of certain agreements among the Company and the holders of such shares. Subject to certain limitations in such agreements, the 47 49 holders of at least 25% of such shares may require, on two occasions, that the Company use its best efforts to register such shares for public resale, subject to certain limitations. If the Company registers any of its Common Stock either for its own account or for the account of other security holders, the holders of such shares are entitled to include their shares of Common Stock in the registration, subject to the ability of the underwriters to limit the number of shares included in the Offerings. The holders of such shares may also require the Company on no more than one occasion every 12 months to register all or a portion of their registrable securities on Form S-3 when use of such form becomes available to the Company, provided, among other limitations, that the proposed aggregate selling price is at least $500,000, and that the total number of permitted demand registrations on Form S-3 is limited to six. All fees, costs and expenses of registrations pursuant to Form S-1 (other than underwriting discounts and commissions) will be borne by the Company. All expenses of demand registrations pursuant to Form S-3 shall be borne by the holders. DELAWARE LAW AND CERTAIN PROVISIONS OF THE THIRD AMENDED AND RESTATED CERTIFICATE OF INCORPORATION The Company is a Delaware corporation and subject to Section 203 of the Delaware General Corporation Law ("DGCL"). In general, Section 203 of the DGCL prevents an "interested stockholder" (defined generally as a person owning 15% or more of a Delaware corporation's outstanding voting stock) from engaging in a "business combination" (as defined) with a Delaware corporation for three years following the date such person became an interested stockholder, subject to certain exceptions such as the approval of the board of directors and of the holders of at least two thirds of the outstanding shares of voting stock not owned by the interested stockholder. The existence of this provision of law can be expected to have the effect of discouraging hostile takeover attempts, including attempts that might result in a premium over the market price for the shares of Common Stock held by stockholders. The Company's Certificate of Incorporation provides that following the date of this Prospectus, the Board of Directors will be divided into three classes of directors with each class serving a staggered three-year term. The classification system of electing directors may tend to discourage a third party from making a tender offer or otherwise attempting to obtain control of the Company and may maintain the incumbency of the Board of Directors, as it generally makes it more difficult for stockholders to replace a majority of the directors. The Company's Certificate of Incorporation also eliminates, upon the closing of the Offerings, the right of stockholders to act without a meeting and does not provide for cumulative voting in the election of directors. These and other provisions may have the effect of deterring hostile takeovers or delaying changes in control or management of the Company. The amendment of any of these provisions would require approval by holders of 66 2/3% or more of the outstanding Common Stock. TRANSFER AGENT AND REGISTRAR The Transfer Agent and Registrar for the Common Stock is The First National Bank of Boston. SHARES ELIGIBLE FOR FUTURE SALE Prior to the Offerings, there has been no public market for the Common Stock. Future sales of substantial amounts of Common Stock in the public market could adversely affect the market price of the Common Stock. Upon completion of the Offerings, the Company will have outstanding an aggregate of 93,007,325 shares of Common Stock, assuming (i) the issuance of 5,000,000 shares of Common Stock in the Offerings, (ii) no exercise of the Underwriters' over-allotment options and (iii) no exercise of options or warrants to purchase Common Stock after October 31, 1996 except for 1,500,000 shares issuable upon exercise of warrants expiring at the close of the Offerings. Of these shares, the 5,000,000 shares sold in the Offerings will be freely tradable without restriction or further 48 50 registration under the Securities Act, except for any shares purchased by "affiliates" of the Company as that term is defined in Rule 144 under the Securities Act. Sales by affiliates will be subject to certain limitations and restrictions described below. Beginning 90 days after the date of this Prospectus, approximately shares will become eligible for sale in the public market subject in some cases to the volume and other restrictions of Rule 144 under the Securities Act. Of these shares, holders of shares and options and warrants to purchase shares are subject to lock-up agreements. Shares covered by these lock-up agreements are subject to restrictions on resale in the public market for a period of 180 days following the date of this Prospectus, subject to release, directly or indirectly, by the Representatives of the Underwriters. Upon expiration of the lock-up period, shares will become eligible for sale in the public market, subject in most cases to the limitations of Rule 144. The remaining shares held by existing stockholders will become eligible for sale at various times over a period of less than two years and could be sold earlier if the holders exercise registration rights. In addition, holders of stock options could exercise these options and sell certain of the shares issued upon exercise as described below. As of October 31, 1996, there were a total of 10,957,960 shares of Common Stock subject to outstanding options under the Amended and Restated 1994 Stock Option Plan, 2,684,355 of which were vested. Promptly following these Offerings, the Company intends to file a registration statement on Form S-8 under the Securities Act to register all of the shares of Common Stock issued or reserved for future issuance under the Option Plan and the Directors Plan. On the date 180 days after the effective date of this Prospectus, a total of shares of Common Stock subject to outstanding options will be vested and exercisable. After the effective date of the registration statement on Form S-8, shares purchased upon exercise of options granted pursuant to the Option Plan or Directors Plan generally would be available for resale in the public market. In general, under Rule 144 as currently in effect, a person (or persons whose shares are aggregated) who has beneficially owned shares for at least two years (including the holding period of any prior owner except an affiliate) is entitled to sell in "broker's transactions" or to market makers, within any three-month period commencing 90 days after the date of this prospectus, a number of shares that does not exceed the greater of (i) one percent of the number of shares of Common Stock then outstanding (approximately 930,000 shares immediately after the Offerings) or (ii) generally, the average weekly trading volume in the Common Stock during the four calendar weeks preceding the required filing of a Form 144 with respect to such sale. Sales under Rule 144 are generally subject to the availability of current public information about the Company. Under Rule 144(k), a person who is not deemed to have been an affiliate of the Company at any time during the 90 days preceding a sale, and who has beneficially owned the shares proposed to be sold for a least three years (including the holding period of any prior owner except an affiliate), is entitled to sell such shares without having to comply with the manner of sale, public information, volume limitation or notice filing provisions of Rule 144. Under Rule 701 under the Securities Act, persons who purchase shares upon exercise of options granted prior to the effective date of the Offerings are entitled to sell such shares 90 days after the date of this Prospectus in reliance on Rule 144, without having to comply with the holding period and notice filing requirements of Rule 144 and, in the case of non-affiliates, without having to comply with the public information, volume limitation or notice filing provisions of Rule 144. The Commission has proposed to amend the holding period required by Rule 144 to permit sales of "restricted securities" after one year rather than two years and to permit "non-affiliates" to sell without restrictions, pursuant to Rule 144(k), after a holding period of two years (including the holding period of any prior owner except an affiliate). If such proposed amendment is adopted, restricted securities would become freely tradable (subject to any applicable contractual restrictions) at correspondingly earlier dates. 49 51 CERTAIN U.S. TAX CONSIDERATIONS APPLICABLE TO NON-U.S. HOLDERS OF THE COMMON STOCK The following is a general discussion of certain U.S. federal income and estate tax consequences of the ownership and disposition of Common Stock by a person that, for U.S. federal income tax purposes, is a non-resident alien individual, a foreign corporation, a foreign partnership or a foreign estate or trust as defined in the U.S. Internal Revenue Code of 1986, as amended (the "Code") (a "non-U.S. holder"). This discussion does not consider specific facts and circumstances that may be relevant to a particular non-U.S. holder's tax position and does not deal with all aspects of United States federal income and estate taxation that may be relevant to non-U.S. holders, or with U.S. state and local or non-U.S. tax consequences. Furthermore, the following discussion is based on provisions of the Code, existing and proposed regulations promulgated thereunder, and administrative and judicial interpretations thereof as of the date hereof, all of which are subject to change, possibly with retroactive effect. Each prospective non-U.S. holder is urged to consult a tax adviser with respect to the U.S. federal tax consequences of holding and disposing of Common Stock, as well as any tax consequences that may arise under the laws of any U.S. state, municipality or other taxing jurisdiction. An individual may, among other ways, be deemed to be a resident alien (as opposed to a non-resident alien) with respect to any calendar year by virtue of being present in the United States on at least 31 days in such calendar year and for an aggregate of at least 183 days during the current calendar year and the two preceding calendar years (counting for such purposes all of the days present in the current year, one-third of the days present in the immediately preceding year, and one-sixth of the days present in the second preceding year). Resident aliens are subject to U.S. federal tax as if they were U.S. citizens. DIVIDENDS As described above, the Company does not expect to pay dividends. In the event the Company does pay dividends, dividends paid to a non-U.S. holder of Common Stock will be subject to withholding of U.S. federal income tax at a rate of 30% of the gross amount of the dividend or such lower rate as may be specified by an applicable income tax treaty, unless the dividends are effectively connected with the conduct of a trade or business by the non-U.S. holder within the United States. Dividends that are effectively connected with such holder's conduct of a trade or business in the United States are subject to U.S. federal income tax on a net income basis at applicable graduated individual or corporate rates, and are not generally subject to withholding, if the holder complies with certain certification and disclosure requirement. Any such effectively connected dividends received by a foreign corporation may also, under certain circumstances, be subject to an additional "branch profits tax" at a 30% rate or such lower rate as may be specified by an applicable income tax treaty. Dividends paid to an address outside the United States are presumed to be paid to a resident of the country of address (unless the payer has knowledge to the contrary) for purposes of the withholdings discussed above and for purposes of determining the applicability of a tax treaty rate. Under proposed U.S. Treasury regulations that are proposed to be effective for distributions after 1997 (the "Proposed Regulations") however, a non-U.S. holder of Common Stock who wishes to claim the benefit of an applicable treaty rate would be required to satisfy applicable certification requirements. The Proposed Regulations include special rules that apply to dividends paid to foreign partnerships. It is not certain whether, or in what form, the Proposed Regulations will be adopted as final regulations. A non-U.S. holder of Common Stock that is eligible for a reduced rate of U.S. withholding tax pursuant to an income tax treaty may obtain a refund of any excess amounts withheld by filing an appropriate claim for refund with the U.S. Internal Revenue Service. 50 52 GAIN ON DISPOSITION OF COMMON STOCK A non-U.S. holder generally will not be subject to U.S. federal income tax in respect of gain recognized on a disposition of Common Stock unless (i) the gain is effectively connected with a trade or business of the non-U.S. holder in the United States or, if a tax treaty applies, is attributable to a permanent establishment maintained by the non-U.S. holder in the United States, (ii) in the case of a non-U.S. holder who is an individual and holds the Common Stock as a capital asset, such holder is present in the United States for 183 or more days in the taxable year of the sale and certain other conditions are met, or (iii) the Company is or has been a "U.S. real property holding corporation" for federal income tax purposes at any time during the five-year period ending on the date of the disposition. The Company believes that it has not been and it is not a "U.S. real property holding corporation" for U.S. federal income tax purposes and does not currently anticipate becoming a "U.S. real property holding corporation." If an individual non-U.S. holder falls under clause (i) above, he or she will be taxed on his or her net gain derived from the sale at regular graduated U.S. federal income tax rates. If an individual non-U.S. holder falls under clause (ii) above, he or she will be subject to a flat 30% tax on the net gain derived from the sale which gain may be offset by U.S. capital losses. If a non-U.S. holder that is a foreign corporation falls under clause (i) above, it will be taxed on its gain at regular graduated U.S. federal income tax rates and, in addition, may be subject to the branch profits tax equal to 30% of its "effectively connected earnings and profits" within the meaning of the Code for the taxable year, as adjusted for certain items, or at such lower rate as may be specified by an applicable income tax treaty. FEDERAL ESTATE TAXES Common Stock owned or treated as owned by a non-U.S. holder at the time of death, or Common Stock of which the non-U.S. holder made certain in lifetime transfers, will be included in such holder's gross estate for U.S. federal estate tax purposes, unless an applicable estate tax treaty provides otherwise. U.S. INFORMATION REPORTING REQUIREMENTS AND BACKUP WITHHOLDING TAX The Company must report annually to the U.S. Internal Revenue Service and to each non-U.S. holder the amount of dividends paid to such holder and the tax withheld with respect to such dividends, regardless of whether withholding was required. Copies of the information returns reporting such dividends and withholding may also be made available to the tax authorities in the country in which the non-U.S. holder resides under the provisions of an applicable income tax treaty. Under current law, backup withholding (which generally is a withholding tax imposed at the rate of 31% on certain payments to persons that fail to furnish certain information under the U.S. information reporting requirements) will generally not apply to dividends paid to a non-U.S. holder at an address outside the United States unless such non-U.S. holder is engaged in a trade or business in the United States or unless the payer has knowledge that the payee is a U.S. person. Under the Proposed Regulations, however, dividend payments generally will be subject to backup withholding unless applicable certification requirements are satisfied. In general, backup withholding and information reporting will not apply to a payment of the proceeds of a sale of Common Stock to or through a foreign office of a broker. If, however, such broker is, for U.S. federal income tax purposes, a U.S. person, a controlled foreign corporation, or a foreign person that derives 50% of more of its gross income for certain periods form the conduct of a trade or business in the United States, such payments will not be subject to backup withholding but will be subject to information reporting, unless (1) such broker has documentary evidence in its records that the beneficial owner is a non-U.S. holder and certain other conditions are met, or (2) the beneficial owner otherwise establishes an exemption. Payment to or through a U.S. office of a broker of the proceeds of a sale of Common Stock is generally subject to both backup withholding and information reporting unless the beneficial owner 51 53 certifies under penalties of perjury that it is a non-U.S. holder, or otherwise establishes an exemption. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against such holder's U.S. federal income tax liability provided the required information is furnished to the U.S. Internal Revenue Service.

The accompanying notes are an integral part of these financial statements. F-6 60 CIENA CORPORATION NOTES TO FINANCIAL STATEMENTS (1) THE COMPANY AND SIGNIFICANT ACCOUNTING POLICIES Description of Business CIENA Corporation (the "Company" or "CIENA"), a Delaware corporation, was incorporated on November 2, 1992 as HydraLite Incorporated. Subsequently, the Company changed its name to Cedrus Corporation and then to CIENA Corporation. The Company designs, manufactures and sells dense wavelength division multiplexing systems for long distance fiberoptic telecommunications networks. During the period from November 2, 1992 to October 31, 1995, CIENA was a development stage company as defined in Statement of Financial Accounting Standards No. 7, "Development Stage Enterprises". Planned principal operations commenced during fiscal 1996 and, accordingly, CIENA is no longer considered a development stage company. During fiscal 1996, all of the Company's revenue was attributable to a single product and to a single customer. Additionally, the Company's access to certain raw materials is dependent upon single and sole source suppliers. Fiscal Year The Company has a 52 or 53 week fiscal year which ends on the Saturday nearest to the last day of October in each year (November 2, 1996; October 28, 1995; and October 29, 1994). For purposes of financial statement presentation, each fiscal year is described as having ended on October 31. Fiscal 1994 and 1995 comprised 52 weeks and fiscal 1996 comprised 53 weeks. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires the Company to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, together with amounts disclosed in the related notes to the financial statements. Particularly sensitive estimates include reserves for warranty and other contractual obligations and for excess and obsolete inventories. Actual results could differ from the recorded estimates. Pro Forma Stockholders' Equity CIENA anticipates filing an initial registration statement with the Securities and Exchange Commission. If the contemplated Offerings are consummated under the terms presently anticipated, each share of the Mandatorily Redeemable Series A, B, and C Preferred Stock (collectively, the "Convertible Preferred Stock") will convert into five shares of the Company's Common Stock. Pro forma stockholders' equity as of October 31, 1996 reflects the anticipated conversion of the Convertible Preferred Stock into Common Stock. Cash and Cash Equivalents The Company considers all highly liquid investments purchased with original maturities of three months or less to be cash equivalents. The Company's entire cash and cash equivalents balance at October 31, 1996 was on deposit with one financial institution, which represents a concentration of credit risk as defined under Statement of Financial Accounting Standards No. 105, "Disclosure of Information about Financial Instruments with Off-Balance-Sheet Risk and Financial Instruments with Concentrations of Credit Risk". The majority of the Company's cash equivalents are invested in overnight repurchase agreements, which are secured by the U.S. Government. F-7 61 CIENA CORPORATION NOTES TO FINANCIAL STATEMENTS -- (CONTINUED) (1) THE COMPANY AND SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED) Inventories Inventories are stated at the lower of cost or market, with cost determined on the first-in, first-out basis. The Company records a provision for excess and obsolete inventory whenever such an impairment has been identified. Equipment, Furniture and Fixtures Equipment, furniture and fixtures are recorded at cost. Depreciation and amortization are computed using the straight-line method over useful lives of 2-5 years for equipment, furniture and fixtures and of 6-10 years for leasehold improvements. Revenue Recognition The Company recognizes product revenue in accordance with the shipping terms specified. For transactions where the Company has yet to obtain customer acceptance or has agreements pertaining to installation services, revenue is deferred until no significant obligations remain. Revenue for installation services is recognized as the services are performed. Amounts received in excess of revenue recognized are included as deferred revenue in the accompanying balance sheets. For distributor sales where risks of ownership have not transferred, the Company recognizes revenue when the product is shipped through to the end user. During fiscal 1996, all of the Company's revenue and related trade accounts receivable were derived from one customer, which is headquartered within the United States. Revenue-Related Accruals The Company provides for the estimated costs to fulfill customer warranty and other contractual obligations upon the recognition of the related revenue. Such reserves are determined based upon actual warranty cost experience, estimates of component failure rates, and management's industry experience. The Company's contractual sales arrangements generally do not permit the right of return of product by the customer. Research and Development The Company charges all research and development costs to expense as incurred. Income Taxes The Company accounts for income taxes in accordance with Statement of Financial Accounting Standards No. 109 (SFAS No. 109), "Accounting for Income Taxes". SFAS No. 109 is an asset and liability approach that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences attributable to differences between the carrying amounts of assets and liabilities for financial reporting purposes and their respective tax bases, and for operating loss and tax credit carryforwards. In estimating future tax consequences, SFAS No. 109 generally considers all expected future events other than the enactment of changes in tax laws or rates. A valuation allowance is recorded if it is "more likely than not" that some portion or all of a deferred tax asset will not be realized. F-8 62 CIENA CORPORATION NOTES TO FINANCIAL STATEMENTS -- (CONTINUED) (1) THE COMPANY AND SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED) Computation of Pro Forma Net Income per Share Pro forma net income per common and common equivalent share is computed using the weighted average number of common and common equivalent shares outstanding. Weighted average common and common equivalent shares include Common Stock, stock options and warrants using the modified treasury stock method and the assumed conversion of all outstanding shares of Convertible Preferred Stock into Common Stock. Since the conversion of the Convertible Preferred Stock has a significant effect on the earnings per share calculation, historical loss per share has not been calculated on the basis that it is irrelevant. Pursuant to the requirements of the Securities and Exchange Commission, Common Stock, stock options, warrants and Convertible Preferred Stock issued by the Company during the twelve months immediately preceding the filing of an initial registration statement and through the effective date of such registration statement have been included in the calculation of the weighted average shares outstanding using the modified treasury stock method based on the estimated initial public offering price. Software Development Costs Statement of Financial Accounting Standards No. 86, "Accounting for the Costs of Computer Software to be Sold, Leased or Otherwise Marketed", requires the capitalization of certain software development costs incurred subsequent to the date technological feasibility is established and prior to the date the product is generally available for sale. The capitalized cost is then amortized over the estimated product life. The Company defines technological feasibility as being attained at the time a working model is completed. To date, the period between achieving technological feasibility and the general availability of such software has been short and software development costs qualifying for capitalization have been insignificant. Accordingly, the Company has not capitalized any software development costs. Accounting for Stock Options In October 1995, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 123 (SFAS No. 123), "Accounting for Stock-Based Compensation". The Company's adoption of SFAS No. 123 in fiscal 1997 will not have any effect on the Company's financial condition or results of operations, as the Company intends to continue to measure compensation cost of stock options granted to employees using the intrinsic value method provided by Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees". (2) INVENTORIES Inventories are comprised of the following (in thousands):

In September 1994 and October 1995, the Company entered into separate master lease agreements to lease certain furniture and equipment. The Company may lease up to a maximum total of $4.5 million of furniture and equipment under these agreements, of which $4.1 million had been utilized as of October 31, 1996. Lease terms range from 36 to 48 months. In accordance with Statement of Financial Accounting Standards No. 13, "Accounting for Leases", the related leases have been recorded as capital lease transactions. Furniture and equipment with a cost of $1,541,000 and $4,105,000 and accumulated depreciation of $311,000 and $1,080,000 have been accounted for as capital lease assets at October 31, 1995 and 1996, respectively. The Company has the option to purchase the assets at the end of the lease term. (4) ACCRUED LIABILITIES Accrued liabilities are comprised of the following (in thousands):

(663) ------- $ 3,146 =======
(6) LINE OF CREDIT In November 1996, the Company entered into an unsecured line of credit agreement with a bank, which provides for borrowings of up to $15,000,000. Interest on borrowings is set at the bank's prime rate (at November 20, 1996 the rate was 8.25%). Among other provisions, the Company is required to maintain certain financial covenants, principally certain minimum working capital levels and monthly profitability levels. The line of credit agreement also prohibits the Company from paying cash dividends on its capital stock, and expires in November 1997. (7) NOTES PAYABLE In June 1996, the Company borrowed $556,000 from the Maryland Economic Development Corporation for construction of leasehold improvements and executed promissory notes of $500,000 and $56,000 with annual interest rates of 6.63% and 3.00%, respectively. Initial interest payments on the notes are due three and six months following the date of disbursement with quarterly principal payments commencing on March 31, 1997. The Company provided $56,000 on deposit in escrow as collateral towards the notes and has recorded such amount as a component of other assets in the accompanying balance sheet. The notes payable are due as follows (in thousands): Fiscal year ending October 31, 1997....................................................... $ 69 1998....................................................... 153 1999....................................................... 104 2000....................................................... 111 2001....................................................... 119 ----- $ 556 =====
(8) MANDATORILY REDEEMABLE PREFERRED STOCK Each holder of Convertible Preferred Stock is entitled to vote on all matters on an as if converted basis. Dividends, if declared by the Board of Directors, are $.06, $.1275 and $.56 per share for the Series A, Series B and Series C Preferred Stock, respectively. No dividends have been declared through fiscal 1996. Subsequent to December 1, 2001, Series A dividends accrue on a quarterly basis and become cumulative. Upon liquidation, holders of the Series A, Series B and F-11 65 CIENA CORPORATION NOTES TO FINANCIAL STATEMENTS -- (CONTINUED) (8) MANDATORILY REDEEMABLE PREFERRED STOCK -- (CONTINUED) Series C Preferred Stock are entitled to receive $1.00, $1.50 and $7.00 per share, respectively, as adjusted for certain defined recapitalization events, plus accrued dividends, if any. Holders of Convertible Preferred Stock may convert each of their shares into five shares of common stock at any time. Each outstanding share of Convertible Preferred Stock will be automatically converted into five shares of Common Stock upon (1) the consummation of the Offerings contemplated by the Company in its anticipated initial registration statement, or (2) the affirmative vote of the holders of record of (a) 67% of the outstanding shares of all series of Convertible Preferred Stock, voting together as one class to that effect, and (b) 85% of the outstanding shares of Series C Preferred Stock, voting separately as a class. Each outstanding share of Convertible Preferred Stock is mandatorily redeemable by the Company at the greater of purchase price or fair value upon the affirmative vote of holders of 72% of the outstanding shares for each individual series. A total of 50% of any such redemption is to be paid seven years from original issuance and 50% eight years from original issuance. The accompanying financial statements do not reflect any accretion to redemption value, because such accretion is not meaningful in light of the contemplated Offerings and the related expected conversion of all Convertible Preferred Stock to Common Stock. During February 1994, the Company received a two month $200,000 bridge loan from two investors that subsequently purchased Series A Preferred Stock shares in April 1994. These two investors received warrants to purchase 50,000 shares of Series A Preferred Stock at either an exercise price of $1.00 per share or at a reduced share quantity for a cashless exercise price. The fair value of these warrants was determined to be immaterial on the date of grant and therefore no charge was recorded. In September 1996, warrants to purchase 50,000 of these shares were exercised and exchanged in a cashless exercise for 47,637 shares. The following is a summary of the Company's Convertible Preferred Stock activity (dollars in thousands):

(9) STOCK OPTIONS AND WARRANTS Stock Warrants In January 1993, the Company issued a fully paid option to acquire up to five percent of the Company's outstanding shares of Common Stock after exercise. This option was issued in connection with the license of certain technologies described in Note 11. This option was redeemed F-12 66 CIENA CORPORATION NOTES TO FINANCIAL STATEMENTS -- (CONTINUED) (9) STOCK OPTIONS AND WARRANTS -- (CONTINUED) for 643,090 shares in early January 1996. As the fair value of these warrants was determined to be immaterial at the date of issuance, no charge to research and development expense was recorded. In connection with the master lease agreement discussed in Note 5, the Company issued in September 1994, for $600, a warrant to the lessor to acquire 600,000 shares of the Company's Common Stock at an exercise price of $0.20 per share. As the fair value of these warrants was determined to be immaterial at the date of issuance, no charge was recorded by the Company. In connection with the 1994 equity offerings, the Company issued warrants to investment bankers to purchase 1,075,000 shares of Common Stock at an exercise price of $0.02 and 150,000 shares of Series A Preferred Stock at an exercise price of $1.00 per share. No charge was recorded relative to these warrants as their fair value was determined to be immaterial. The warrants for the purchase of 1,075,000 shares of Common Stock were exercised in December 1994 for a $21,500 purchase price. During 1995, the warrants to purchase 150,000 shares of Series A Preferred Stock at $1.00 per share were canceled in exchange for the Company granting options to purchase 300,000 shares of Series B Preferred Stock at $2.00 per share. During August 1996, in connection with the settlement of litigation involving a dispute over certain rights awarded from the April 1994 equity offerings of Series A Preferred Stock, the Company issued, for $150, a warrant to an investor to acquire 75,000 shares of the Company's Common Stock at an exercise price of $4.00 per share. The Company recorded approximately $156,000 in expense for the fair value of the warrant when granted. Stock Incentive Plans The Company has an Amended and Restated 1994 Stock Option Plan (the "1994 Plan"). Under the 1994 Plan, 20,050,000 shares of the Company's authorized but unissued Common Stock are reserved for options issuable to employees. These options are immediately exercisable upon grant, and both the options and the shares issuable upon exercise of the options generally vest to the employee over a four year period. The Company has the right to repurchase any exercised and non-vested shares at the original purchase price from the employees upon termination of employment. In June 1996 the Company approved the 1996 Outside Directors Stock Option Plan (the "1996 Plan"). Under the 1996 Plan, 750,000 shares of the Company's authorized but unissued Common Stock are reserved for options issuable to outside members of the Company's Board of Directors. These options vest to the director over periods from one to three years, depending on the type of option granted, and are exercisable once vested. Under the 1994 Plan and the 1996 Plan, options may be incentive stock options or non-statutory options, and the exercise price for each option shall be established by the Board of Directors provided, however, that the exercise price per share shall not be not less than the fair market value for incentive stock options and not less than F-13 67 CIENA CORPORATION NOTES TO FINANCIAL STATEMENTS -- (CONTINUED) (9) STOCK OPTIONS AND WARRANTS -- (CONTINUED) 85% of fair market value for non-statutory stock options. Following is a summary of the Company's stock option and warrant activity:
NUMBER OF SHARES (IN THOUSANDS) ------------------------------------------- PREFERRED PREFERRED COMMON STOCK STOCK STOCK EXERCISE ------------------- SERIES A SERIES B PRICE OPTIONS WARRANTS WARRANTS WARRANTS PER SHARE ------- -------- -------- -------- ---------- Balance at October 31, 1993................ -- 386 -- -- $.00- .10 Granted............................... 3,560 1,916 200 -- .00- 1.00 ------- -------- ------ ------ ---------- Balance at October 31, 1994................ 3,560 2,302 200 -- .00- 1.00 Granted............................... 3,856 49 -- 300 .00- 2.00 Exercised.............................

All of the outstanding warrants above are currently exercisable, except the Common Stock warrant for 75,000 shares granted to an investor in August 1996. This warrant becomes exercisable in August 1997. Approximately 3.3 million of the total outstanding options and warrants were vested at October 31, 1996. (10) INCOME TAXES In fiscal 1996, the provision for income taxes consists of the following (in thousands): Current: Federal...................................................... $ 3,452 State........................................................ 632 -------- 4,084 -------- Deferred: Federal...................................................... (1,690) State........................................................ (144) -------- (1,834) -------- $ 2,250 ========
In fiscal 1994 and 1995, the tax provision was comprised primarily of a tax benefit of approximately $960,000 and $3.1 million, respectively, which was offset by valuation allowance of the same amount. In fiscal 1994 and 1995, the tax provision differed from the expected tax benefit, computed by applying the U.S. federal statutory rate of 35% to the loss before income taxes, principally due to the effect of increases in the valuation allowance. In fiscal 1996, the tax provision reconciles to the F-14 68 CIENA CORPORATION NOTES TO FINANCIAL STATEMENTS -- (CONTINUED) (10) INCOME TAXES -- (CONTINUED) amount computed by multiplying income before income taxes by the U.S. federal statutory rate of 35% as follows: Provision at statutory rate......................................... 35.0% Reversal of valuation allowance..................................... (24.3) State taxes, net of federal benefit................................. 2.9 Current tax credits................................................. (1.1) Other............................................................... 0.8 ---- 13.3% ====
The components of deferred tax assets were as follows (in thousands):
OCTOBER 31, ------------------- 1995 1996 -------- ------- Reserve for excess and obsolete inventories.............. $ -- $ 736 Accrued warranty and other contractual obligations....... -- 602 Start-up costs deferred for tax purposes................. 496 379 Other accrued expenses not deducted for tax.............. -- 114 Accrual to cash basis adjustments........................ 689 -- Net operating loss carryforward.......................... 2,814 -- Other.................................................... 51 3 -------- ------- Gross deferred tax assets........................... 4,050 1,834 Valuation allowance................................. (4,050) -- -------- ------- Net deferred tax asset......................... $ -- $ 1,834 ======== =======
The increase in the valuation allowance during fiscal 1995 was primarily attributable to the increase in net operating losses. The reversal of the valuation allowance during the third quarter of fiscal 1996 was attributable to the receipt of product acceptance by the Company from its initial customer and the start of profitable operations during that period. In assessing the realizability of deferred tax assets, management considers whether it is "more likely than not" (as defined under SFAS No. 109) that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers projected future taxable income and tax planning strategies in making this assessment. Based upon their evaluation of the evidence relating to net deferred tax assets at October 31, 1995, management determined that realization was not "more likely than not" and, accordingly, established a valuation allowance of $4.1 million. (11) LICENSE AGREEMENT The Company has an exclusive agreement to license certain technologies which requires a 7.5% royalty on sales of products using the licensed technologies or certain minimum annual requirements. To date, the Company has incurred only the minimum annual royalty fees of $50,000 and $100,000 for the years ended October 31, 1995 and 1996, respectively. The Company may terminate the agreement upon notice to the licensor and would be liable for any payments accrued or owed prior to such termination. F-15 69 CIENA CORPORATION NOTES TO FINANCIAL STATEMENTS -- (CONTINUED) (12) EMPLOYEE BENEFIT PLANS In January 1995, the Company adopted a 401(k) defined contribution profit sharing plan. The plan covers all full-time employees who are at least 21 years of age, have completed three months of service and are not covered by a collective bargaining agreement where retirement benefits are subject to good faith bargaining. Participants may contribute up to 15% of pretax compensation, subject to certain limitations. The Company may make discretionary annual profit sharing contributions of up to the lesser of $30,000 or 25% of each participant's compensation. The Company has made no profit sharing contributions to date. (13) COMMITMENTS AND CONTINGENCIES Operating Lease Commitments The Company has certain minimum obligations under noncancelable operating leases expiring on various dates through 2006 for equipment and facilities. Future annual minimum rental commitments under noncancelable operating leases at October 31, 1996 are as follows (in thousands): Fiscal Year Ending ------------------------------------------------------------------ 1997.............................................................. $ 1,487 1998.............................................................. 1,816 1999.............................................................. 1,807 2000.............................................................. 1,796 2001.............................................................. 1,796 Thereafter........................................................ 7,245 -------- $ 15,947 ========
Rental expense for fiscal 1994, 1995 and 1996 was approximately $42,000, $111,000 and $602,000, respectively. Litigation In November 1996, a stockholder and entities controlled by that stockholder (the "plaintiffs") who provided initial equity capital during the formation of the Company and participated in the Series C Preferred Stock financing, filed suit against the Company and certain directors of the Company (the "defendants"). This suit alleges that the plaintiffs were entitled by the terms of an agreement with the Company to purchase approximately 230,000 shares of additional Series C Preferred Stock, at $7.00 per share, at the time of the closing of the Series C Preferred Stock financing, but were denied that opportunity by the defendants. The plaintiffs seek to recover unspecified actual and punitive damages. The Company believes that the plaintiffs' claims are without merit and intends to defend itself vigorously. However, due to the very early stage of this matter, it is not possible to determine what impact, if any, the outcome of this litigation might have on the financial condition, results of operations or cash flows of the Company. The Company has agreed to indemnify its customer for liability incurred in connection with the infringement of a third-party's intellectual property rights. Although the Company has not received notice from its customer advising the Company of any alleged infringement of a third-party's intellectual property rights, there can be no assurance that such indemnification of alleged liability will not be required from the Company in the future. Substantial inventories of intellectual property are held by a few industry participants and major universities and research laboratories. The Company has on a few occasions hired personnel from F-16 70 CIENA CORPORATION NOTES TO FINANCIAL STATEMENTS -- (CONTINUED) (13) COMMITMENTS AND CONTINGENCIES -- (CONTINUED) such parties. The Company has in the past received letters from legal counsel to one such party, asserting that the hiring of their personnel involves a compromise of that party's intellectual properties. The Company disagrees with such assertions and, if any formal claim were to be filed, the Company would vigorously defend itself. Such litigation could be very expensive to defend, regardless of the merits of any possible claim. (14) SUBSEQUENT EVENTS On November 22, 1996, the Company's Board of Directors approved the following effective on December 9, 1996: (i) a five-for-one stock split of the Company's Common Stock; (ii) an increase in the number of Common Stock authorized from 112,500,000 to 180,000,000; (iii) an increase in the number of shares of Common Stock issuable upon conversion of the Convertible Preferred Stock from one-for-one to five-for-one, and (iv) the authorization of 20,000,000 shares of undesignated Preferred Stock. All references to the number of shares authorized, issued and outstanding, the Preferred Stock to Common Stock conversion factor and per share information for all periods presented have been adjusted to give effect to the aforementioned stock split and share authorizations. On December 10, 1996, the Company's Board of Directors authorized management of the Company to file a registration statement with the Securities and Exchange Commission for the initial public offering of its common stock. The Company plans to issue 5,000,000 shares at an estimated initial public offering price of between $17 and $19 per share.

The U.S. Underwriters propose to offer the shares of Common Stock in part directly to the public at the initial public offering price set forth on the cover page of this Prospectus and in part to certain securities dealers at such price less a concession of $ per share. The U.S. Underwriters may allow, and such dealers may reallow, a concession not in excess of $ per share to certain brokers and dealers. After the shares of Common Stock are released for sale to the public, the offering price and other selling terms may from time to time be varied by the representatives. The Company has entered into an underwriting agreement (the "International Underwriting Agreement") with the underwriters of the international offering (the "International Underwriters") providing for the concurrent offer and sale of 1,000,000 shares of Common Stock in an international offering outside the United States. The offering price and aggregate underwriting discounts and commissions per share for the two offerings are identical. The closing of the offering made hereby is a condition to the closing of the international offering, and vice versa. The representatives of the International Underwriters are Goldman Sachs International, Alex. Brown & Sons Incorporated, Wessels, Arnold & Henderson, L.L.C. and William K. Woodruff & Company. Pursuant to an Agreement between the U.S. and International Underwriting Syndicates (the "Agreement Between") relating to the two offerings, each of the U.S. Underwriters named herein has agreed that, as a part of the distribution of the shares offered hereby and subject to certain exceptions, it will offer, sell or deliver the shares of Common Stock, directly or indirectly, only in the United States of America (including the States and the District of Columbia), its territories, its possessions and other areas subject to its jurisdiction (the "United States") and to U.S. persons, which term shall mean, for purposes of this paragraph: (a) any individual who is a resident of the United States or (b) any corporation, partnership or other entity organized in or under the laws of the United States or any political subdivision thereof and whose office most directly involved with the purchase is located in the United States. Each of the International Underwriters has agreed pursuant to the Agreement Between that, as part of the distribution of the shares offered as a part of the international offering, and subject to certain exceptions, it will (i) not, directly or indirectly, offer, sell or deliver shares of Common Stock (a) in the United States or to any U.S. persons or (b) to any person whom it believes intends to reoffer, resell or deliver the shares in the United States or to any U-1 72 U.S. persons, and (ii) cause any dealer to whom it may sell such shares at any concession to agree to observe a similar restriction. Pursuant to the Agreement Between, sales may be made between the U.S. Underwriters and the International Underwriters of such number of shares of Common Stock as may be mutually agreed. The price of any shares so sold shall be the initial public offering price, less an amount not greater than the selling concession. The Company has granted the U.S. Underwriters an option exercisable for 30 days after the date of this Prospectus to purchase up to an aggregate of 600,000 additional shares of Common Stock solely to cover over-allotments, if any. If the U.S. Underwriters exercise their over-allotment option, the U.S. Underwriters have severally agreed, subject to certain conditions, to purchase approximately the same percentage thereof that the number of shares to be purchased by each of them, as shown in the foregoing table, bears to the 4,000,000 shares of Common Stock offered. The Company has granted the International Underwriters a similar option to purchase up to an aggregate of 150,000 additional shares of Common Stock. The Company, optionholders, warrantholders and certain stockholders of the Company have agreed that, during the period beginning from the date of this Prospectus and continuing to and including the date 180 days after the date of the Prospectus, they will not offer, sell, contract to sell or otherwise dispose of any securities of the Company (other than pursuant to employee stock option plans existing, or on the conversion or exchange of convertible or exchangeable securities outstanding, on the date of this Prospectus) which are substantially similar to the shares of the Common Stock or which are convertible into or exchangeable for securities which are substantially similar to the shares of Common Stock without the prior written consent of the Representatives, except for the shares of Common Stock offered in connection with the concurrent U.S. and international offerings. The representatives of the Underwriters have informed the Company that they do not expect sales to accounts over which the Underwriters exercise discretionary authority to exceed five percent of the total number of shares of Common Stock offered by them. Prior to the Offerings, there has been no public market for the shares. The initial public offering price will be negotiated between the Company and the representatives of the U.S. Underwriters and the International Underwriters. Among the factors to be considered in determining the initial public offering price of the Common Stock, in addition to prevailing market conditions, will be the Company's historical performance, estimates of the business potential and earnings prospects of the Company, an assessment of the Company's management and the consideration of the above factors in relation to market valuation of companies in related businesses. Under the terms of a settlement agreement with the Company entered into in August 1996, the Company has (i) agreed to retain Woodruff as one of the representatives of the United States Underwriters and the International Underwriters, (ii) granted Woodruff warrants to purchase 75,000 shares at a purchase price of $4.00 per share and (iii) made a cash payment to Woodruff of $87,500. See "Certain Transactions -- Litigation Settlement". Application will be made for quotation of the Common Stock on the Nasdaq National Market under the symbol "CIEN". The Company has agreed to indemnify the Underwriters against certain liabilities, including liabilities under the Securities Act. U-2 73 This Prospectus may be used by underwriters and dealers in connection with offers and sales of the Common Stock, including shares initially sold in the international offering, to persons located in the United States.

- --------------- * To be supplied by amendment. ITEM 14. INDEMNIFICATION OF OFFICERS AND DIRECTORS Section 145 of the Delaware General Corporation Law permits indemnification of officers, directors and other corporate agents under certain circumstances and subject to certain limitations. The Registrant's Third Amended and Restated Certificate of Incorporation and bylaws provide that the Registrant shall indemnify its directors, officers, employees and agents to the full extent permitted by Delaware General Corporation Law, including in circumstances in which indemnification is otherwise discretionary under Delaware law. In addition, the Registrant has entered into separate indemnification agreements with its directors, officers and certain employees which require the Registrant, among other things, to indemnify them against certain liabilities which may arise by reason of their status or service (other than liabilities arising from willful misconduct of a culpable nature) and to maintain directors' and officers' liability insurance, if available on reasonable terms. The Registrant intends to obtain directors' and officers' liability insurance with up to $10 million coverage per occurrence. These indemnification provisions and the indemnification agreement to be entered into between the Registrant and its officers and directors may be sufficiently broad to permit indemnification of the Registrant's officers and directors for liabilities (including reimbursement of expenses incurred) arising under the Securities Act. The Underwriting Agreements filed as Exhibits 1.1 and 1.2 to this Registration Statement provide for indemnification by the Underwriters of the Registrant and its officers and directors for certain liabilities arising under the Securities Act, or otherwise. ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES Since December 1993, the Registrant has sold and issued the following unregistered securities (stated after giving effect to a 1,333.33-for-1 stock split in April 1994 and a five-for-one stock split effective on December 9, 1996). (1) In April 1994, the Registrant sold 3,332,520 shares of Series A Preferred Stock for an aggregate price of $3,332,520.

(4) In October 1994, the Registrant sold 250,000 shares of Common Stock for an aggregate price of $5,000.

(11) In September 1996, the Registrant sold 23,848 shares of Series A Preferred Stock upon a cashless exercise of a warrant. (12) From December 1, 1993 through October 31, 1996, the Registrant has sold an aggregate of 623,495 shares for an aggregate consideration of $82,268 upon exercise of stock options granted pursuant to the Registrant's Amended and Restated 1994 Stock Option Plan. The issuances described above were deemed to be exempt from registration under the Securities Act in reliance on Section 4(2) of the Securities Act as transactions by an issuer not involving a public offering. In addition, certain issuances described in Paragraph 13 were deemed exempt from registration under the Securities Act in reliance on Rule 701 promulgated thereunder as transactions pursuant to compensatory benefit plans and contracts relating to compensation. The recipients of securities in each such transaction represented their intention to acquire the securities for investment only and not with a view to or for sale in connection with any distribution thereof and appropriate legends were affixed to the share certificates and other instruments issued in such transactions. All recipients either received adequate information about the Registrant or had access, through employment or other relationships, to such information. Effective upon the completion of the Offerings being registered hereby, all of the issued and outstanding shares of the Company's Convertible Preferred Stock will automatically convert into 73,315,740 shares of the Company's Common Stock. The Registrant will rely upon the exemption from registration contained in Section 3(a)(9) of the Securities Act. ITEM 16. EXHIBITS (a) Exhibits.

ITEM 17. UNDERTAKINGS The undersigned Registrant hereby undertakes to provide to the Underwriters at the closing specified in the Underwriting Agreements certificates in such denominations and registered in such names as required by the Underwriters to permit prompt delivery to each purchaser. Insofar as indemnification by the Registrant for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the provisions referenced in Item 14 of this Registration Statement or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act, and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer, or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered hereunder, the Registrant will, II-3 79 unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue. The undersigned Registrant hereby undertakes that: (1) For purposes of determining any liability under the Securities Act, the information omitted from the form of Prospectus filed as part of this Registration Statement in reliance upon Rule 430A and contained in a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this Registration Statement as of the time it was declared effective; and (2) For the purpose of determining any liability under the Securities Act, each post-effective amendment that contains a form of Prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at the time shall be deemed to be the initial bona fide offering thereof. II-4 80 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the Registrant has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Savage, County of Howard, State of Maryland, on the 12th day of December, 1996.

New York, New York 10004

Ladies and Gentlemen:

                 CIENA Corporation, a Delaware corporation (the "Company"),
proposes, subject to the terms and conditions stated herein, to issue and sell
to the Underwriters named in Schedule I hereto (the "Underwriters") an
aggregate of 4,000,000 shares (the "Firm Shares") and, at the election of the
Underwriters, up to 600,000 additional shares (the "Optional Shares") of Common
Stock, par value $.01 per share ("Stock"), of the Company (the Firm Shares and
the Optional Shares that the Underwriters elect to purchase pursuant to Section
2 hereof being collectively called the "Shares").

                 It is understood and agreed to by all parties that the Company
is concurrently entering into an agreement (the "International Underwriting
Agreement") providing for the sale by the Company of up to a total of 1,150,000
shares of Stock (the "International Shares"), including the over-allotment
option thereunder, through arrangements with certain underwriters outside the
United States (the "International Underwriters"), for whom Goldman Sachs
International, Alex. Brown & Sons Incorporated, Wessels, Arnold & Henderson,
L.L.C. and William K. Woodruff & Company are acting as lead managers.  Anything
herein or therein to the contrary notwithstanding, the respective closings

   2

under this Agreement and the International Agreement are hereby expressly made
conditional on one another.  The Underwriters hereunder and the International
Underwriters are simultaneously entering into an Agreement between U.S. and
International Underwriting Syndicates (the "Agreement between Syndicates")
which provides, among other things, for the transfer of shares of Stock between
the two syndicates.  Two forms of prospectus are to be used in connection with
the offering and sale of shares of Stock contemplated by the foregoing, one
relating to the Shares hereunder and the other relating to the International
Shares.  The latter form of prospectus will be identical to the former except
for certain substitute pages.  Except as used in Sections 2, 3, 4, 9 and 11
herein, and except as the context may otherwise require, references hereinafter
to the Shares shall include all the shares of Stock which may be sold pursuant
to either this Agreement or the International Underwriting Agreement, and
references herein to any prospectus whether in preliminary or final form, and
whether as amended or supplemented, shall include both the U.S. and the
international versions thereof.

                 1.  The Company represents and warrants to, and agrees with,
each of the Underwriters that:

                             (a)           A registration statement on Form S-1
                 (File No. 333-_________) (the "Initial Registration
                 Statement") in respect of the Shares has been filed with the
                 Securities and Exchange Commission (the "Commission"); the
                 Initial Registration Statement and any post-effective
                 amendment thereto, each in the form heretofore delivered to
                 you, and, excluding exhibits thereto, to you for each of the
                 other Underwriters, have been declared effective by the
                 Commission in such form; other than a registration statement,
                 if any, increasing the size of the offering (a "Rule 462(b)
                 Registration Statement"), filed pursuant to Rule 462(b) under
                 the Securities Act of 1933, as amended (the "Act"), which will
                 become effective upon filing, no other document with respect
                 to the Initial Registration Statement has heretofore been
                 filed with the Commission; and no stop order suspending the
                 effectiveness of the Initial Registration Statement, any
                 post-effective amendment thereto or the Rule 462(b)
                 Registration Statement, if any, has been issued and no
                 proceeding for that purpose has been initiated or threatened
                 by the Commission (any preliminary prospectus included in the
                 Initial Registration Statement or filed with the Commission
                 pursuant to Rule 424(a) of the rules and regulations of the
                 Commission under the Act, is hereinafter called a "Preliminary
                 Prospectus"; the various parts of the Initial Registration
                 Statement and the Rule 462(b) Registration Statement, if any,
                 including all exhibits thereto and including the information
                 contained in the form of final prospectus filed with the
                 Commission pursuant to Rule 424(b) under the Act in accordance
                 with Section 5(a) hereof and deemed by virtue of Rule 430A
                 under the Act to be part of the Initial Registration Statement
                 at the time it was declared effective, each as amended at the
                 time such part of the registration statement became effective
                 or such part of the Rule 462(b) Registration Statement, if
                 any, became or hereafter becomes effective, are hereinafter
                 collectively called the "Registration Statement"; and such
                 final prospectus, in the form first filed pursuant to Rule
                 424(b) under the Act, is hereinafter called the "Prospectus").

                             (b)           No order preventing or suspending
                 the use of any Preliminary Prospectus has been issued by the

                 exercisable or exchangeable securities outstanding as of, the
                 date of this Agreement), without the Company's prior written
                 consent, which consent in no instance has been given or agreed
                 to be given and which consent in any instance will be given or
                 agreed to be given without your prior written consent.

the Underwriters agrees, severally and not jointly, to purchase from the
Company, at a purchase price per share of $_____________ the number of Firm
Shares set forth opposite the name of such Underwriter in Schedule I hereto and
(b) in the event and to the extent that the Underwriters shall exercise the
election to purchase Optional Shares as provided below, the Company agrees to
issue and sell to each of the Underwriters, and each of the Underwriters
agrees, severally and not jointly, to purchase from the Company, at the
purchase price per share set forth in clause (a) of this Section 2, that
portion of the number of Optional Shares as to
   7

eliminate fractional shares) determined by multiplying such number of Optional
Shares by a fraction, the numerator of which is the maximum number of Optional
Shares which such Underwriter is entitled to purchase as set forth opposite the
name of such Underwriter in Schedule I hereto and the denominator of which is
the maximum number of Optional Shares that all of the Underwriters are entitled

                 the Shares and if at such time any event shall have occurred
                 as a result of which the Prospectus as then amended or

                 fact or omit to state any material fact necessary in order to
                 make the statements therein, in the light of the circumstances

                 as a foreign corporation for the transaction of business and

                                    (iv)    Nothing has come to the attention
                 of such counsel that causes it to believe  real property and
                 buildings held under lease by the Company are not held by it
                 under valid leases with such exceptions as are not material
                 and do not interfere with the use made and proposed to be made
                 of such property and buildings by the Company;

                                    (v)     This Agreement and the

                 of Delivery of the transactions herein and therein
                 contemplated do not conflict with or result in a breach or
                 violation of any of the terms or provisions of, or constitute
                 a default under, any agreement or instrument filed as an
                 exhibit to the Registration Statement, nor will such action
                 result in any violation of the provisions of the Certificate
                 of Incorporation or By-laws of the Company or any statute,
                 order, rule or regulation known to such counsel of any court
                 or governmental agency or body having jurisdiction over the
                 Company or any of its properties;

                 as of the Time of Delivery, except the registration under the
                 Act of the Shares, and such consents, approvals,
                 authorizations, registrations or qualifications as may be
                 required under state or foreign securities or Blue Sky laws in

                 the Underwriters and the International Underwriters;

                                    (viii)  The statements set forth in the
                 Prospectus under the caption "Description of Capital Stock",
                 insofar as they purport to constitute a summary of the terms
                 of the Stock, under the caption "Certain U.S.  Tax
                 Considerations Applicable to Non-U.S. Holders of the Common

                                    (ix)    The Company is not an "investment
                 company" as such term is defined in the Investment Company
                 Act;

                                    (x)     To the best of such counsel's
                 knowledge, the Company has not issued any outstanding
                 securities convertible into or exchangeable for, or
                 outstanding options, warrants or other rights to purchase or
                 to subscribe for any shares or other securities of the
                 Company, except as described in the Prospectus;

                                    (xi)    No holder of outstanding shares of
                 capital stock of the Company has (i) any statutory preemptive
                 right under the Delaware General Corporation Law or, (ii) to
                 such counsel's knowledge and except as has been waived, 
                 any contractual right to subscribe for any shares of
                 capital stock of the Company (including the Shares being
                 delivered at such Time of Delivery) (except that no opinion
                 need be expressed with respect to the specific matters that
                 are the subject of the legal proceedings disclosed in the
                 Prospectus under the caption "Business--Legal Proceedings") or
                 to have any common stock or other securities of the Company
                 included in the Registration Statement or the right, as a
                 result of the filing of the Registration Statement, to require
                 registration of any shares of Common Stock or other securities
                 of the Company; and

                                    (xii)   The Registration Statement and the
                 Prospectus and any further amendments and supplements thereto
                 made by the Company prior to such Time of Delivery (other than
                 the financial statements and notes thereto, financial
                 schedules and other financial data included therein, as to
                 which such counsel need express no opinion) comply as to form
                 in all material respects with the requirements of the Act and
                 the rules and
   13
                 regulations thereunder.

                 In addition to the matters set forth above, such letter shall
                 also contain statements of such counsel to the effect that (i)
                 to such counsel's knowledge and other than as set forth in the
                 Prospectus, there are no legal or governmental proceedings
                 pending to which the Company is a party or of which any
                 property of the Company is the subject which, if determined
                 adversely to the Company could reasonably be expected
                 individually or in the aggregate to have a material adverse
                 effect on the financial condition or results of operations of
                 the Company, and, to such counsel's knowledge, no such
                 proceedings are threatened by governmental authorities or
                 threatened by others; (ii) while such counsel are not passing
                 upon and do not assume responsibility for, the accuracy,
                 completeness or fairness of the Registration Statement or the
                 Prospectus, except for those statements referred to in the
                 opinion in subsection (viii) of this Section 7(c), or any
                 further amendment or supplement thereto, based upon the
                 procedures referred to in such letter no facts have come to
                 the attention of such counsel which lead them to believe that,
                 as of its effective date, the Registration Statement or any
                 further amendment thereto made by the Company prior to such
                 Time of Delivery (other than the financial statements and
                 notes thereto, financial schedules and other financial data
                 included therein, as to which such counsel need express no
                 opinion) contained an untrue statement of a material fact or
                 omitted to state a material fact required to be stated therein
                 or necessary to make the statements therein not misleading or
                 that, as of its date, the Prospectus or any further amendment
                 or supplement thereto made by the Company prior to such Time
                 of Delivery (other than the financial statements and notes
                 thereto, financial schedules and other financial data included
                 therein, as to which such counsel need express no opinion)
                 contained an untrue statement of a material fact or omitted to
                 state a material fact necessary to make the statements
                 therein, in the light of the circumstances under which they
                 were made, not misleading or that, as of such Time of
                 Delivery, the Prospectus or any further amendment or
                 supplement thereto made by the Company prior to such Time of
                 Delivery (other than the financial statements and notes
                 thereto, schedules and other financial data included therein,
                 as to which such counsel need express no opinion) contains an
                 untrue statement of a material fact or omits to state a
                 material fact necessary to make the statements therein, in the
                 light of the circumstances under which they were made, not
                 misleading; and (iii) they do not know of any amendment to the
                 Registration Statement required to be filed or of any
                 contracts or other documents of a character required to be
                 filed as an exhibit to the Registration Statement or required
                 to be described in the Registration Statement or the
                 Prospectus which are not filed or described as required.

                  In rendering such opinion, such counsel may state that they
express no opinion as to the laws of any jurisdiction other than the Federal
laws of the United States, the laws of the State of Maryland, the contract law
of the State of New York and the General Corporation Law of the State of
Delaware.

                             (d)  Gray Cary Ware & Friedenrich, special patent 
                 counsel for the Company, shall have furnished its written
                 opinion to the Company, dated on or before such Time

   14
                 with respect to certain patent law matters.

                             (e)    The Vice President and General Counsel of
                 the Company shall have furnished to you his written opinion (a
                 draft of such opinion is attached as Annex II(c) hereto),
                 dated such Time of Delivery, in form and substance
                 satisfactory to you, to the effect that:

                 its By-Laws; and

                                    (ii)     To such counsel's knowledge and 
                 other than as described in the Prospectus, there are no legal 
                 or governmental proceedings pending to which the Company is a
                 party or of which any property of the Company is the subject;
                 and, to such counsel's knowledge, no such proceedings are
                 threatened by governmental authorities or by others.

                             (f)    On the date of the Prospectus at a time
                 prior to the execution of this Agreement, at 9:30 a.m., New
                 York City time, on the effective date of any post-effective
                 amendment to the Registration Statement filed subsequent to

                 Price Waterhouse LLP shall have furnished to you a letter or
                 letters, dated the respective dates of delivery thereof, in
                 form and substance satisfactory to you, to the effect set
                 forth in Annex I hereto (the executed copy of the letter
                 delivered prior to the execution of this Agreement is attached
                 as Annex I(a) hereto and a draft of the form of letter to be
                 delivered on the effective date of any post-effective
                 amendment to the Registration Statement and as of each Time of
                 Delivery is attached as Annex I(b) hereto;

                             (g)  (i)  The Company shall not have sustained
                 since the date of the latest audited financial statements
                 included in the Prospectus any loss or interference with its
                 business from fire, explosion, flood or other calamity,
                 whether or not covered by insurance, or from any labor dispute
                 or court or governmental action, order or decree, otherwise
                 than as set forth or contemplated in the Prospectus, and (ii)
                 since the respective dates as of which information is given in
                 the Prospectus there shall not have been any change in the
                 capital stock or long-term debt of the Company or any change,
                 or any development reasonably likely to result in a
                 prospective change, in or affecting the general affairs,
                 management, financial position, stockholders' equity or
                 results of operations of the Company, otherwise than as set
                 forth or contemplated in the Prospectus, the effect of which,
                 in any such case described in Clause (i) or (ii), is in the
                 judgment of the Representatives so material and adverse as to
                 make it impracticable or inadvisable to proceed with the
                 public offering or the delivery of the Shares being delivered
                 at such Time of Delivery on the terms and in the manner
                 contemplated in the Prospectus;

                             (h)    On or after the date hereof there shall not
                 have occurred any of the following: (i) a suspension or
                 material limitation in trading in securities generally on the
                 New York Stock Exchange or on NASDAQ; (ii) a suspension or
                 material limitation in trading in the Company's securities on
                 NASDAQ; (iii) a general moratorium on commercial banking
                 activities declared by either Federal, New York State or
                 Maryland State authorities; or (iv) the outbreak or escalation
                 of hostilities involving the United States or the declaration
                 by the United States of a national emergency or war, if the
                 effect of any such event specified in this Clause (iv) in the
                 judgment of the Representatives makes it impracticable or
                 inadvisable
   15
                 to proceed with the public offering or the delivery of the
                 Shares being delivered at such Time of Delivery on the terms
                 and in the manner contemplated in the Prospectus;

                             (i)    The Shares to be sold at such Time of
                 Delivery shall have been duly approved for quotation on
                 NASDAQ;

                             (j)     The Company has obtained and delivered to
                 the Underwriters executed copies of an agreement from
                 ___________________________________, substantially to the
                 effect set forth in Subsection 5(f) hereof in form and
                 substance satisfactory to you;

                             (k)    The Company shall have complied with the
                 provisions of Section 5(c) hereof with respect to furnishing
                 of Prospectuses on the New York Business Day next succeeding
                 the date of this Agreement; and

                             (l)    The Company shall have furnished or caused
                 to be furnished to you at such Time of Delivery certificates
                 of officers of the Company satisfactory to you as to the
                 accuracy of the representations and warranties of the Company
                 herein at and as of such Time of Delivery, as to the
                 performance by the Company of all of its obligations hereunder
                 to be performed at or prior to such Time of Delivery, as to
                 the matters set forth in subsections (a) and (g) of this
                 Section and as to such other matters as you may reasonably
                 request.

                 8.          (a)    The Company will indemnify and hold
                 harmless each Underwriter against any losses, claims, damages
                 or liabilities, joint or several, to which such Underwriter
                 may become subject, under the Act or otherwise, insofar as
                 such losses, claims, damages or liabilities (or actions in
                 respect thereof) arise out of or are based upon an untrue
                 statement or alleged untrue statement of a material fact
                 contained in any Preliminary Prospectus, the Registration
                 Statement or the Prospectus, or any amendment or supplement
                 thereto, or arise out of or are based upon the omission or
                 alleged omission to state therein a material fact required to
                 be stated therein or necessary to make the statements therein
                 not misleading, and will reimburse each Underwriter for any
                 legal or other expenses reasonably incurred by such
                 Underwriter in connection with investigating or defending any
                 such action or claim as such expenses are incurred; provided,
                 however, that the Company shall not be liable in any such case
                 to the extent that any such loss, claim, damage or liability
                 arises out of or is based upon an untrue statement or alleged
                 untrue statement or omission or alleged omission made in any
                 Preliminary Prospectus, the Registration Statement or the
                 Prospectus or any such amendment or supplement in reliance
                 upon and in conformity with written information furnished to
                 the Company by any Underwriter through Goldman, Sachs & Co.
                 expressly for use therein.

                             (b)    Each Underwriter will indemnify and hold
                 harmless the Company against any losses, claims, damages or
                 liabilities to which the Company may become subject, under the
                 Act or otherwise, insofar as such losses, claims, damages or
                 liabilities (or actions in respect thereof) arise out of or
                 are based upon an untrue statement or alleged untrue statement
                 of a material fact contained in any Preliminary Prospectus,
                 the Registration Statement or the
   16
                 Prospectus, or any amendment or supplement thereto, or arise
                 out of or are based upon the omission or alleged omission to
                 state therein a material fact required to be stated therein or
                 necessary to make the statements therein not misleading, in
                 each case to the extent, but only to the extent, that such
                 untrue statement or alleged untrue statement or omission or
                 alleged omission was made in any Preliminary Prospectus, the
                 Registration Statement or the Prospectus or any such amendment
                 or supplement in reliance upon and in conformity with written
                 information furnished to the Company by such Underwriter
                 through Goldman, Sachs & Co. expressly for use therein; and
                 will reimburse the Company for any legal or other expenses
                 reasonably incurred by the Company in connection with
                 investigating or defending any such action or claim as such
                 expenses are incurred.

                             (c)    Promptly after receipt by an indemnified
                 party under subsection (a) or (b) above of notice of the
                 commencement of any action, such indemnified party shall, if a
                 claim in respect thereof is to be made against the
                 indemnifying party under such subsection, notify the
                 indemnifying party in writing of the commencement thereof; but
                 the omission so to notify the indemnifying party shall not
                 relieve it from any liability which it may have to any
                 indemnified party otherwise than under such subsection.  In
                 case any such action shall be brought against any indemnified
                 party and it shall notify the indemnifying party of the
                 commencement thereof, the indemnifying party shall be entitled
                 to participate therein and, to the extent that it shall wish,
                 jointly with any other indemnifying party similarly notified,
                 to assume the defense thereof, with counsel satisfactory to
                 such indemnified party (who shall not, except with the consent
                 of the indemnified party, be counsel to the indemnifying
                 party), and, after notice from the indemnifying party to such
                 indemnified party of its election so to assume the defense
                 thereof, the indemnifying party shall not be liable to such
                 indemnified party under such subsection for any legal expenses
                 of other counsel or any other expenses, in each case
                 subsequently incurred by such indemnified party, in connection
                 with the defense thereof other than reasonable costs of
                 investigation.  No indemnifying party shall, without the
                 written consent of the indemnified party, effect the
                 settlement or compromise of, or consent to the entry of any
                 judgment with respect to, any pending or threatened action or
                 claim in respect of which indemnification or contribution may
                 be sought hereunder (whether or not the indemnified party is
                 an actual or potential party to such action or claim) unless
                 such settlement, compromise or judgment (i) includes an
                 unconditional release of the indemnified party from all
                 liability arising out of such action or claim and (ii) does
                 not include a statement as to or an admission of fault,
                 culpability or a failure to act, by or on behalf of any
                 indemnified party.

                             (d)    If the indemnification provided for in this
                 Section 8 is unavailable to or insufficient to hold harmless
                 an indemnified party under subsection (a) or (b) above in
                 respect of any losses, claims, damages or liabilities (or
                 actions in respect thereof) referred to therein, then each
                 indemnifying party shall contribute to the amount paid or
                 payable by such indemnified party as a result of such losses,
                 claims, damages or liabilities (or actions in respect thereof)
                 in such proportion as is appropriate to reflect the relative
                 benefits received by
   17
                 the Company on the one hand and the Underwriters on the other
                 from the offering of the Shares.  If, however, the allocation
                 provided by the immediately preceding sentence is not
                 permitted by applicable law or if the indemnified party failed
                 to give the notice required under subsection (c) above, then
                 each indemnifying party shall contribute to such amount paid
                 or payable by such indemnified party in such proportion as is
                 appropriate to reflect not only such relative benefits but
                 also the relative fault of the Company on the one hand and the
                 Underwriters on the other in connection with the statements or
                 omissions which resulted in such losses, claims, damages or
                 liabilities (or actions in respect thereof), as well as any
                 other relevant equitable considerations.  The relative
                 benefits received by the Company on the one hand and the
                 Underwriters on the other shall be deemed to be in the same
                 proportion as the total net proceeds from the offering of the
                 Shares purchased under this Agreement (before deducting
                 expenses) received by the Company bear to the total
                 underwriting discounts and commissions received by the
                 Underwriters with respect to the Shares purchased under this
                 Agreement, in each case as set forth in the table on the cover
                 page of the Prospectus. The relative fault shall be determined
                 by reference to, among other things, whether the untrue or
                 alleged untrue statement of a material fact or the omission or
                 alleged omission to state a material fact relates to
                 information supplied by the Company on the one hand or the
                 Underwriters on the other and the parties' relative intent,
                 knowledge, access to information and opportunity to correct or
                 prevent such statement or omission.  The Company and the
                 Underwriters agree that it would not be just and equitable if
                 contributions pursuant to this subsection (d) were determined
                 by pro rata allocation (even if the Underwriters were treated
                 as one entity for such purpose) or by any other method of
                 allocation which does not take account of the equitable
                 considerations referred to above in this subsection (d).  The
                 amount paid or payable by an indemnified party as a result of
                 the losses, claims, damages or liabilities (or actions in
                 respect thereof) referred to above in this subsection (d)
                 shall be deemed to include any legal or other expenses
                 reasonably incurred by such indemnified party in connection
                 with investigating or defending any such action or claim.
                 Notwithstanding the provisions of this subsection (d), no
                 Underwriter shall be required to contribute any amount in
                 excess of the amount by which the total price at which the
                 Shares underwritten by it and distributed to the public were
                 offered to the public exceeds the amount of any damages which
                 such Underwriter has otherwise been required to pay by reason
                 of such untrue or alleged untrue statement or omission or
                 alleged omission.  No person guilty of fraudulent
                 misrepresentation (within the meaning of Section 11(f) of the
                 Act) shall be entitled to contribution from any person who was
                 not guilty of such fraudulent misrepresentation.  The
                 Underwriters' obligations in this subsection (d) to contribute
                 are several in proportion to their respective underwriting
                 obligations and not joint.

                             (e)    The obligations of the Company under this
                 Section 8 shall be in addition to any liability which the
                 Company may otherwise have and shall extend, upon the same
                 terms and conditions, to each person, if any, who controls any
                 Underwriter within the meaning of the Act; and the obligations
                 of the Underwriters under this Section 8 shall be in addition
                 to any liability which the respective Underwriters may
                 otherwise have and shall extend, upon the same terms and
                 conditions, to each officer and director of the Company and to
                 each person, if any, who controls the Company within the
                 meaning of the Act.

                 9.          (a)    If any Underwriter shall default in its
                 obligation to purchase the Shares which it has agreed to
                 purchase hereunder at a Time of Delivery, you may in your
                 discretion arrange for you or another party or other parties
                 to purchase such Shares on the terms contained herein.  If
                 within thirty-six hours after such default by any Underwriter
                 you do not arrange for the purchase of such Shares, then the
                 Company shall be entitled to a further period of thirty-six
                 hours within which to procure another party or other parties
                 satisfactory to you to purchase such Shares on such terms.  In
                 the event that, within the respective prescribed periods, you
                 notify the Company that you have so arranged for the purchase
                 of such Shares, or the Company notifies you that it has so
                 arranged for the purchase of such
   18
                 Shares, you or the Company shall have the right to postpone
                 such Time of Delivery for a period of not more than seven
                 days, in order to effect whatever changes may thereby be made
                 necessary in the Registration Statement or the Prospectus, or
                 in any other documents or arrangements, and the Company agrees
                 to file promptly any amendments to the Registration Statement
                 or the Prospectus which in your opinion may thereby be made
                 necessary.  The term "Underwriter" as used in this Agreement
                 shall include any person substituted under this Section with
                 like effect as if such person had originally been a party to
                 this Agreement with respect to such Shares.

                             (b)    If, after giving effect to any arrangements
                 for the purchase of the Shares of a defaulting Underwriter or
                 Underwriters by you and the Company as provided in subsection
                 (a) above, the aggregate number of such Shares which remains
                 unpurchased does not exceed one-eleventh of the aggregate
                 number of all the Shares to be purchased at such Time of
                 Delivery, then the Company shall have the right to require
                 each non-defaulting Underwriter to purchase the number of
                 Shares which such Underwriter agreed to purchase hereunder at
                 such Time of Delivery and, in addition, to require each
                 non-defaulting Underwriter to purchase its pro rata share
                 (based on the number of Shares which such Underwriter agreed
                 to purchase hereunder) of the Shares of such defaulting
                 Underwriter or Underwriters for which such arrangements have
                 not been made; but nothing herein shall relieve a defaulting
                 Underwriter from liability for its default.

                             (c)    If, after giving effect to any arrangements
                 for the purchase of the Shares of a defaulting Underwriter or
                 Underwriters by you and the Company as provided in subsection
                 (a) above, the aggregate number of such Shares which remains
                 unpurchased exceeds one-eleventh of the aggregate number of
                 all the Shares to be purchased at such Time of Delivery, or if
                 the Company shall not exercise the right described in
                 subsection (b) above to require non-defaulting Underwriters to
                 purchase Shares of a defaulting Underwriter or Underwriters,
                 then this Agreement (or, with respect to the Second Time of
                 Delivery, the obligations of the Underwriters to purchase and
                 of the Company to sell the Optional Shares) shall thereupon
                 terminate, without liability on the part of any non-defaulting
                 Underwriter or the Company, except for the expenses to be
                 borne by the Company and the Underwriters as provided in
                 Section 6 hereof and the indemnity and contribution agreements
                 in Section 8 hereof; but nothing herein shall relieve a
                 defaulting Underwriter from liability for its default.

                 10.  The respective indemnities, agreements, representations,
warranties and other statements of the Company and the several Underwriters, as
set forth in this Agreement or made by or on behalf of them, respectively,
pursuant to this Agreement, shall remain in full force and effect, regardless
of any investigation (or any statement as to the results thereof) made by or on
behalf of any Underwriter or any controlling person of any Underwriter, or the
Company, or any officer or director or controlling person of the Company, and
shall survive delivery of and payment for the Shares.

                 11.  If this Agreement shall be terminated pursuant to Section
9 hereof, the Company shall not then be under any liability to any Underwriter
except as provided in Sections 6 and 8 hereof; but, if for any other reason,
any Shares are not delivered by or on behalf of the Company as provided herein,
the Company will reimburse the Underwriters through you for all out-of-pocket
expenses approved in writing by you, including fees and disbursements of
counsel, reasonably incurred by the Underwriters in making preparations for the
purchase, sale and delivery of the Shares not so delivered, but the Company
shall then be under no further liability to any Underwriter in respect of the
Shares not so delivered except as provided in Sections 6 and 8 hereof.

                 12.  In all dealings hereunder, you shall act on behalf of
each of the Underwriters, and the
   19
parties hereto shall be entitled to act and rely upon any statement, request,
notice or agreement on behalf of any Underwriter made or given by you jointly
or by Goldman, Sachs & Co. on behalf of you as the representatives.

                 All statements, requests, notices and agreements hereunder
shall be in writing, and if to the Underwriters shall be delivered or sent by
mail, telex or facsimile transmission to you as the representatives in care of
Goldman, Sachs & Co., 85 Broad Street, New York, New York  10004, Attention:
Registration Department; and if to the Company shall be delivered or sent by
mail, telex or facsimile transmission to the address of the Company set forth
in the Registration Statement, Attention: Secretary; provided, however, that
any notice to an Underwriter pursuant to Section 8(c) hereof shall be delivered
or sent by mail, telex or facsimile transmission to such Underwriter at its
address set forth in its Underwriters' Questionnaire, or telex constituting
such Questionnaire, which address will be supplied to the Company by you upon
request.  Any such statements, requests, notices or agreements shall take
effect at the time of receipt thereof.

                 13.  This Agreement shall be binding upon, and inure solely to
the benefit of, the Underwriters, the Company and, to the extent provided in
Sections 8 and 10 hereof, the officers and directors of the Company and each
person who controls the Company or any Underwriter, and their respective heirs,
executors, administrators, successors and assigns, and no other person shall
acquire or have any right under or by virtue of this Agreement.  No purchaser
of any of the Shares from any Underwriter shall be deemed a successor or assign
by reason merely of such purchase.

                 14.  Time shall be of the essence of this Agreement.  As used
herein, the term "business day" shall mean any day when the Commission's office
in Washington, D.C., is open for business.

                 15.  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

                 16.  This Agreement may be executed by any one or more of the
parties hereto in any number of counterparts, each of which shall be deemed to
be an original, but all such counterparts shall together constitute one and the
same instrument.
   20

please sign and return to us one for the Company and for each of the
Representatives plus one for each counsel counterparts hereof, and upon the

22 ANNEX I DESCRIPTION OF COMFORT LETTER Pursuant to Section 7(e) of the Underwriting Agreement, the accountants shall furnish letters to the Underwriters to the effect that: (i) They are independent certified public accountants with respect to the Company within the meaning of the Act and the applicable published rules and regulations thereunder; (ii) In their opinion, the financial statements and any supplementary financial information and schedules (and, if applicable, financial forecasts and/or pro forma financial information) examined by them and included in the Prospectus or the Registration Statement comply as to form in all material respects with the applicable accounting requirements of the Act and the related published rules and regulations thereunder; and, if applicable, they have made a review in accordance with standards established by the American Institute of Certified Public Accountants of the unaudited consolidated interim financial statements, selected financial data, pro forma financial information, financial forecasts and/or condensed financial statements derived from audited financial statements of the Company for the periods specified in such letter, as indicated in their reports thereon, copies of which have been furnished separately to the representatives of the Underwriters (the "Representatives") and are attached hereto; (iii) They have made a review in accordance with standards established by the American Institute of Certified Public Accountants of the unaudited condensed consolidated statements of income, consolidated balance sheets and consolidated statements of cash flows included in the Prospectus as indicated in their reports thereon copies of which are attached hereto and on the basis of specified procedures including inquiries of officials of the Company who have responsibility for financial and accounting matters regarding whether the unaudited condensed consolidated financial statements referred to in paragraph (vi)(A)(i) below comply as to form in all material respects with the applicable accounting requirements of the Act and the related published rules and regulations, nothing came to their attention that caused them to believe that the unaudited condensed consolidated financial statements do not comply as to form in all material respects with the applicable accounting requirements of the Act and the related published rules and regulations; (iv) The unaudited selected financial information with respect to the consolidated results of operations and financial position of the Company for the five most recent fiscal years included in the Prospectus agrees with the corresponding amounts (after restatements where applicable) in the audited consolidated financial statements for such five fiscal years; (v) They have compared the information in the Prospectus under selected captions with the disclosure requirements of Regulation S-K and on the basis of limited procedures specified in such letter nothing came to their attention as a result of the foregoing procedures that caused them to believe that this information does not conform in all material respects with the disclosure requirements of Items 301, 302, 402 and 503(d), respectively, of Regulation S-K; 23 (vi) On the basis of limited procedures, not constituting an examination in accordance with generally accepted auditing standards, consisting of a reading of the unaudited financial statements and other information referred to below, a reading of the latest available interim financial statements of the Company, inspection of the minute books of the Company and its subsidiaries since the date of the latest audited financial statements included in the Prospectus, inquiries of officials of the Company responsible for financial and accounting matters and such other inquiries and procedures as may be specified in such letter, nothing came to their attention that caused them to believe that: (A) (i) the unaudited consolidated statements of income, consolidated balance sheets and consolidated statements of cash flows included in the Prospectus do not comply as to form in all material respects with the applicable accounting requirements of the Act and the related published rules and regulations, or (ii) any material modifications should be made to the unaudited condensed consolidated statements of income, consolidated balance sheets and consolidated statements of cash flows included in the Prospectus for them to be in conformity with generally accepted accounting principles; (B) any other unaudited income statement data and balance sheet items included in the Prospectus do not agree with the corresponding items in the unaudited consolidated financial statements from which such data and items were derived, and any such unaudited data and items were not determined on a basis substantially consistent with the basis for the corresponding amounts in the audited consolidated financial statements included in the Prospectus; (C) the unaudited financial statements which were not included in the Prospectus but from which were derived any unaudited condensed financial statements referred to in Clause (A) and any unaudited income statement data and balance sheet items included in the Prospectus and referred to in Clause (B) were not determined on a basis substantially consistent with the basis for the audited consolidated financial statements included in the Prospectus; (D) any unaudited pro forma consolidated condensed financial statements included in the Prospectus do not comply as to form in all material respects with the applicable accounting requirements of the Act and the published rules and regulations thereunder or the pro forma adjustments have not been properly applied to the historical amounts in the compilation of those statements; (E) as of a specified date not more than five days prior to the date of such letter, there have been any changes in the consolidated capital stock (other than issuances of capital stock upon exercise of options and stock appreciation rights, upon earn-outs of performance shares and upon conversions of convertible securities, in each case which were outstanding on the date of the latest financial statements included in the Prospectus) or any increase in the consolidated long-term debt of the Company, or any decreases in consolidated net current assets or stockholders' equity or other items specified by the Representatives, or any increases in any items specified by the Representatives, in each case as compared with amounts shown in the latest balance sheet included in the Prospectus, except in each case for changes, increases or decreases which the Prospectus discloses have occurred or may occur or which are described in such letter; and (F) for the period from the date of the latest financial statements included in the Prospectus to the specified date referred to in Clause (E) there were any decreases in 24 consolidated net revenues or operating profit or the total or per share amounts of consolidated net income or other items specified by the Representatives, or any increases in any items specified by the Representatives, in each case as compared with the comparable period of the preceding year and with any other period of corresponding length specified by the Representatives, except in each case for decreases or increases which the Prospectus discloses have occurred or may occur or which are described in such letter; and (vii) In addition to the examination referred to in their report(s) included in the Prospectus and the limited procedures, inspection of minute books, inquiries and other procedures referred to in paragraphs (iii) and (vi) above, they have carried out certain specified procedures, not constituting an examination in accordance with generally accepted auditing standards, with respect to certain amounts, percentages and financial information specified by the Representatives, which are derived from the general accounting records of the Company, which appear in the Prospectus, or in Part II of, or in exhibits and schedules to, the Registration Statement specified by the Representatives, and have compared certain of such amounts, percentages and financial information with the accounting records of the Company and have found them to be in agreement. 25 ANNEX I(a) COMFORT LETTER DELIVERED PRIOR TO EXECUTION OF THIS AGREEMENT 26 ANNEX I(b) UPDATED COMFORT LETTER 27 ANNEX II(a) OPINION OF UNDERWRITERS COUNSEL 28 ANNEX II(b) OPINION OF COMPANY COUNSEL 29 ANNEX II(c) OPINION OF GENERAL COUNSEL

Goldman Sachs International,
Alex. Brown & Sons Incorporated,
Wessels, Arnold & Henderson, L.L.C.,
William K. Woodruff & Company,
  As representatives of the several Underwriters
   named in Schedule I hereto,
c/o Goldman Sachs International,
Peterborough Court,
133 Fleet Street,
London EC4A 2BB, England.

Ladies and Gentlemen:

                 CIENA Corporation, a Delaware corporation (the "Company"),
proposes, subject to the terms and conditions stated herein, to issue and sell
to the Underwriters named in Schedule I hereto (the "Underwriters") an
aggregate of 1,000,000 shares (the "Firm Shares") and, at the election of the
Underwriters, up to 150,000 additional shares (the "Optional Shares") of Common
Stock, par value $.01 per share (the "Stock"), of the Company (the Firm Shares
and the Optional Shares which the Underwriters elect to purchase pursuant to
Section 2 hereof being collectively called the "Shares").

                 It is understood and agreed to by all parties that the Company
is concurrently entering into an agreement, a copy of which is attached hereto
(the "U.S. Underwriting Agreement"), providing for the offering by the Company
of up to a total of 4,600,000 shares of Stock (the "U.S. Shares") including the
over-allotment option thereunder through arrangements with certain underwriters
in the United States (the "U.S. Underwriters"), for whom Goldman, Sachs & Co.,
Alex. Brown & Sons Incorporated, Wessels, Arnold & Henderson, L.L.C. and
William K. Woodruff & Company are acting as representatives. Anything herein
and therein to the contrary notwithstanding, the respective closings under this
Agreement and the U.S. Underwriting Agreement are hereby expressly made
conditional on one another.  The Underwriters hereunder and the U.S.
Underwriters are simultaneously entering into an Agreement between U.S. and
International Underwriting Syndicates (the "Agreement between Syndicates")
which provides, among other things, for the transfer of shares of Stock between
the two syndicates and for consultation by the Lead Managers hereunder with
Goldman, Sachs & Co. prior to exercising the rights of the Underwriters under
Section 7 hereof.  Two forms of prospectus are to be used in connection with
the offering and sale of shares of Stock contemplated by the foregoing, one
relating to the Shares hereunder and the other relating to the U.S. Shares.
The latter form of prospectus will be identical to the former except for
certain substitute
   2
pages.  Except as used in Sections 2, 3, 4, 9 and 11 herein, and except as the
context may otherwise require, references hereinafter to the Shares shall
include all of the shares of Stock which may be sold pursuant to either this
Agreement or the U.S. Underwriting Agreement, and references herein to any
prospectus whether in preliminary or final form, and whether as amended or
supplemented, shall include both of the U.S. and the international versions
thereof.

                 In addition, this Agreement incorporates by reference certain
provisions from the U.S. Underwriting Agreement (including the related
definitions of terms, which are also used elsewhere herein) and, for purposes
of applying the same, references (whether in these precise words or their
equivalent) in the incorporated provisions to the "Underwriters" shall be to
the Underwriters hereunder, to the "Shares" shall be to the Shares hereunder as
just defined, to "this Agreement" (meaning therein the U.S. Underwriting
Agreement) shall be to this Agreement (except where this Agreement is already
referred to or as the context may otherwise require) and to the representatives
of the Underwriters or to Goldman, Sachs & Co. shall be to the addressees of
this Agreement and to Goldman Sachs International ("GSI"), and, in general, all
such provisions and defined terms shall be applied mutatis mutandis as if the
incorporated provisions were set forth in full herein having regard to their
context in this Agreement as opposed to the U.S. Underwriting Agreement.

                 1.            The Company hereby makes with the Underwriters
the same representations, warranties and agreements as are set forth in Section
1 of the U.S. Underwriting Agreement, which Section is incorporated herein by
this reference.

                 2.            Subject to the terms and conditions herein set
forth, (a) the Company agrees to issue and sell to each of the Underwriters,
and each of the Underwriters agrees, severally and not jointly, to purchase
from the Company, at a purchase price per share of $______, the number of Firm
Shares set forth opposite the name of such Underwriter in Schedule I hereto and
(b) in the event and to the extent that the Underwriters shall exercise the
election to purchase Optional Shares as provided below, the Company agrees to
issue and sell to each of the Underwriters, and each of the Underwriters
agrees, severally and not jointly, to purchase from the Company, at the
purchase price per share set forth in clause (a) of this Section 2, that
portion of the number of Optional Shares as to which such election shall have
been exercised (to be adjusted by you so as to eliminate fractional shares)
determined by multiplying such number of Optional Shares by a fraction the
numerator of which is the maximum number of Optional Shares which such
Underwriter is entitled to purchase as set forth opposite the name of such
Underwriter in Schedule I hereto and the denominator of which is the maximum
number of Optional Shares that all of the Underwriters are entitled to purchase
hereunder.

                 The Company hereby grants to the Underwriters the right to
purchase at their election up to 150,000 Optional Shares, at the purchase price
per share set forth in the paragraph above, for the sole purpose of covering
over-allotments in the sale of the Firm Shares.  Any such election to purchase
Optional Shares may be exercised only by written notice from you to the
Company, given within a period of 30 calendar days after the date of this
Agreement, setting forth the aggregate number of Optional Shares to be
purchased and the date on which such Optional Shares are to be delivered, as
determined by you but in no event earlier than the First Time of Delivery (as
defined in Section 4 hereof) or, unless you and the Company otherwise agree in
writing, earlier than two or later than ten business days after the date of
such notice.

                 3.            Upon the authorization by GSI of the release of
the Firm Shares, the several Underwriters propose to offer the Firm Shares for
sale upon the terms and conditions set forth in the Prospectus and in the forms
of Agreement among Underwriters (International Version) and Selling Agreements,
which have been previously submitted to the Company by you.  Each Underwriter
hereby





                                      -2-
   3
makes to and with the Company the representations and agreements of such
Underwriter as a member of the selling group contained in Sections 3(d) and
3(e) of the form of Selling Agreements.

                 4.            (a) The Shares to be purchased by each
Underwriter hereunder, in definitive form, and in such authorized denominations
and registered in such names as GSI may request upon at least forty-eight
hours' prior notice to the Company shall be delivered by or on behalf of the
Company to GSI, for the account of such Underwriter, against payment by or on
behalf of such Underwriter of the purchase price therefor by certified or
official bank check or checks, payable to the order of the Company in Federal
(same day) funds. The Company will cause the certificates representing the
Shares to be made available for checking and packaging at least twenty-four
hours prior to the Time of Delivery (as defined below) with respect thereto at
the office of GSI, 85 Broad Street, New York, New York 10004 (the "Designated
Office").  The time and date of such delivery and payment shall be, with
respect to the Firm Shares, 9:30 a.m., New York City time, on ____________,
1997 or such other time and date as GSI and the Company may agree upon in
writing, and, with respect to the Optional Shares, 9:30 a.m., New York City
time, on the date specified by GSI in the written notice given by GSI of the
Underwriters' election to purchase such Optional Shares, or such other time and
date as GSI and the Company may agree upon in writing.  Such time and date for
delivery of the Firm Shares is herein called the "First Time of Delivery", such
time and date for delivery of the Optional Shares, if not the First Time of
Delivery, is herein called the "Second Time of Delivery", and each such time
and date for delivery is herein called a "Time of Delivery".

                               (b)   The documents to be delivered at each Time
of Delivery by or on behalf of the parties hereto pursuant to Section 7 of the
U.S. Underwriting Agreement, including the cross receipt for the Shares and any
additional documents requested by the Underwriters pursuant to Section 7(k) of
the U.S. Underwriting Agreement hereof, will be delivered at the offices of
Hale and Dorr, The Willard Building, 1455 Pennsylvania Avenue, N.W.,
Washington, D.C. 20004 (the "Closing Location"), and the Shares will be
delivered at the Designated Office, all at such Time of Delivery.  A meeting
will be held at the Closing Location at 4:00 p.m., New York City time, on the
New York Business Day next preceding such Time of Delivery, at which meeting
the final drafts of the documents to be delivered pursuant to the preceding
sentence will be available for review by the parties hereto.  For the purposes
of this Section 4, "New York Business Day" shall mean each Monday, Tuesday,
Wednesday, Thursday and Friday which is not a day on which banking institutions
in New York are generally authorized or obligated by law or executive order to
close.

                 5.            The Company hereby makes to the Underwriters the
same agreements as are set forth in Section 5 of the U.S. Underwriting
Agreement, which Section is incorporated herein by this reference.

                 6.            The Company and the Underwriters hereby agree
with respect to certain expenses on the same terms as are set forth in Section
6 of the U.S. Underwriting Agreement, which Section is incorporated herein by
this reference.

                 7.            Subject to the provisions of the Agreement
between Syndicates, the obligations of the Underwriters hereunder shall be
subject, in their discretion, at each Time of Delivery, to the condition that
all representations and warranties and other statements of the Company herein
are, at and as of such Time of Delivery, true and correct, the condition that
the Company shall have performed all of its obligations hereunder theretofore
to be performed, and additional conditions identical to those set forth in
Section 7 of the U.S. Underwriting Agreement, which Section is incorporated
herein by this reference.

                 8.            (a)   The Company will indemnify and hold
harmless each Underwriter against any losses, claims, damages or liabilities,
joint or several, to which such Underwriter may become subject, under the Act
or otherwise, insofar as such losses, claims, damages or liabilities (or
actions in respect





                                      -3-
   4
thereof) arise out of or are based upon an untrue statement or alleged untrue
statement of a material fact contained in any Preliminary Prospectus, the
Registration Statement or the Prospectus, or any amendment or supplement
thereto, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to
make the statements therein not misleading, and will reimburse each Underwriter
for any legal or other expenses reasonably incurred by such Underwriter in
connection with investigating or defending any such action or claim as such
expenses are incurred; provided, however, that the Company shall not be liable
in any such case to the extent that any such loss, claim, damage or liability
arises out of or is based upon an untrue statement or alleged untrue statement
or omission or alleged omission made in any Preliminary Prospectus, the
Registration Statement or the Prospectus or any such amendment or supplement in
reliance upon and in conformity with written information furnished to the
Company by any Underwriter through GSI expressly for use therein.

                               (b)   Each Underwriter will indemnify and hold
harmless the Company against any losses, claims, damages or liabilities to
which the Company may become subject, under the Act or otherwise, insofar as
such losses, claims, damages or liabilities (or actions in respect thereof)
arise out of or are based upon an untrue statement or alleged untrue statement
of a material fact contained in any Preliminary Prospectus, the Registration
Statement or the Prospectus, or any amendment or supplement thereto, or arise
out of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, in each case to the extent, but only to the extent,
that such untrue statement or alleged untrue statement or omission or alleged
omission was made in any Preliminary Prospectus, the Registration Statement or
Prospectus or any such amendment or supplement in reliance upon and in
conformity with written information furnished to the Company by such
Underwriter through GSI expressly for use therein; and will reimburse the
Company for any legal or other expenses reasonably incurred by the Company in
connection with investigating or defending any such action or claim as such
expenses are incurred.

                               (c)   Promptly after receipt by an indemnified
party under subsection (a) or (b) above of notice of the commencement of any
action, such indemnified party shall, if a claim in respect thereof is to be
made against the indemnifying party under such subsection, notify the
indemnifying party in writing of the commencement thereof; but the omission so
to notify the indemnifying party shall not relieve it from any liability which
it may have to any indemnified party otherwise than under such subsection.  In
case any such action shall be brought against any indemnified party and it
shall notify the indemnifying party of the commencement thereof, the
indemnifying party shall be entitled to participate therein and, to the extent
that it shall wish, jointly with any other indemnifying party similarly
notified, to assume the defense thereof, with counsel satisfactory to such
indemnified party (who shall not, except with the consent of the indemnified
party, be counsel to the indemnifying party), and, after notice from the
indemnifying party to such indemnified party of its election so to assume the
defense thereof, the indemnifying party shall not be liable to such indemnified
party under such subsection for any legal expenses of other counsel or any
other expenses, in each case subsequently incurred by such indemnified party,
in connection with the defense thereof other than reasonable costs of
investigation.  No indemnifying party shall, without the written consent of the
indemnified party, effect the settlement or compromise of, or consent to the
entry of any judgment with respect to, any pending or threatened action or
claim in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified party is an actual or potential party
to such action or claim) unless such settlement, compromise or judgment (i)
includes an unconditional release of the indemnified party from all liability
arising out of such action or claim and (ii) does not include a statement as to
or an admission of fault, culpability or a failure to act, by or on behalf of
any indemnified party.

                               (d)   If the indemnification provided for in
this Section 8 is unavailable to or insufficient to hold harmless an
indemnified party under subsection (a) or (b) above in respect of any losses,
claims,





                                      -4-
   5
damages or liabilities (or actions in respect thereof) referred to therein,
then each indemnifying party shall contribute to the amount paid or payable by
such indemnified party as a result of such losses, claims, damages or
liabilities (or actions in respect thereof) in such proportion as is
appropriate to reflect the relative benefits received by the Company on the one
hand and the Underwriters on the other from the offering of the Shares.  If,
however, the allocation provided by the immediately preceding sentence is not
permitted by applicable law or if the indemnified party failed to give the
notice required under subsection (c) above, then each indemnifying party shall
contribute to such amount paid or payable by such indemnified party in such
proportion as is appropriate to reflect not only such relative benefits but
also the relative fault of the Company on the one hand and the Underwriters on
the other in connection with the statements or omissions which resulted in such
losses, claims, damages or liabilities (or actions in respect thereof), as well
as any other relevant equitable considerations.  The relative benefits received
by the Company on the one hand and the Underwriters on the other shall be
deemed to be in the same proportion as the total net proceeds from the offering
of the Shares purchased under this Agreement (before deducting expenses)
received by the Company bear to the total underwriting discounts and
commissions received by the Underwriters with respect to the Shares purchased
under this Agreement, in each case as set forth in the table on the cover page
of the Prospectus relating to such Shares. The relative fault shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to
state a material fact relates to information supplied by the Company on the one
hand or the Underwriters on the other and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission.  The Company and the Underwriters agree that it would
not be just and equitable if contributions pursuant to this subsection (d) were
determined by pro rata allocation (even if the Underwriters were treated as one
entity for such purpose) or by any other method of allocation which does not
take account of the equitable considerations referred to above in this
subsection (d).  The amount paid or payable by an indemnified party as a result
of the losses, claims, damages or liabilities (or actions in respect thereof)
referred to above in this subsection (d) shall be deemed to include any legal
or other expenses reasonably incurred by such indemnified party in connection
with investigating or defending any such action or claim.  Notwithstanding the
provisions of this subsection (d), no Underwriter shall be required to
contribute any amount in excess of the amount by which the total price at which
the Shares underwritten by it and distributed to the public were offered to the
public exceeds the amount of any damages which such Underwriter has otherwise
been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission.  No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. The Underwriters' obligations in this subsection (d) to
contribute are several in proportion to their respective underwriting
obligations and not joint.

                               (e)   The obligations of the Company under this
Section 8 shall be in addition to any liability which the Company may otherwise
have and shall extend, upon the same terms and conditions, to each person, if
any, who controls any Underwriter within the meaning of the Act; and the
obligations of the Underwriters under this Section 8 shall be in addition to
any liability which the respective Underwriters may otherwise have and shall
extend, upon the same terms and conditions, to each officer and director of the
Company and to each person, if any, who controls the Company within the meaning
of the Act.

                 9.            (a)   If any Underwriter shall default in its
obligation to purchase the Shares which it has agreed to purchase hereunder at
a Time of Delivery, you may in your discretion arrange for you or another party
or other parties to purchase such Shares on the terms contained herein.  If
within thirty-six hours after such default by any Underwriter you do not
arrange for the purchase of such Shares, then the Company shall be entitled to
a further period of thirty-six hours within which to procure another party or
other parties satisfactory to you to purchase such Shares on such terms. In the
event that, within the respective prescribed periods, you notify the Company
that you have so arranged for the purchase of such





                                      -5-
   6
Shares, or the Company notifies you that it has so arranged for the purchase of
such Shares, you or the Company shall have the right to postpone such Time of
Delivery for a period of not more than seven days, in order to effect whatever
changes may thereby be made necessary in the Registration Statement or the
Prospectus, or in any other documents or arrangements, and the Company agrees
to file promptly any amendments to the Registration Statement or the Prospectus
which in your opinion may thereby be made necessary.  The term "Underwriter" as
used in this Agreement shall include any person substituted under this Section
with like effect as if such person had originally been a party to this
Agreement with respect to such Shares.

                               (b)   If, after giving effect to any
arrangements for the purchase of the Shares of a defaulting Underwriter or
Underwriters by you and the Company as provided in subsection (a) above, the
aggregate number of such Shares which remains unpurchased does not exceed
one-eleventh of the aggregate number of all the Shares to be purchased at such
Time of Delivery, then the Company shall have the right to require each
non-defaulting Underwriter to purchase the number of shares which such
Underwriter agreed to purchase hereunder at such Time of Delivery and, in
addition, to require each non-defaulting Underwriter to purchase its pro rata
share (based on the number of Shares which such Underwriter agreed to purchase
hereunder) of the Shares of such defaulting Underwriter or Underwriters for
which such arrangements have not been made; but nothing herein shall relieve a
defaulting Underwriter from liability for its default.

                               (c)   If, after giving effect to any
arrangements for the purchase of the Shares of a defaulting Underwriter or
Underwriters by you and the Company as provided in subsection (a) above, the
aggregate number of such Shares which remains unpurchased exceeds one-eleventh
of the aggregate number of all the Shares to be purchased at such Time of
Delivery, or if the Company shall not exercise the right described in
subsection (b) above to require non-defaulting Underwriters to purchase Shares
of a defaulting Underwriter or Underwriters, then this Agreement (or, with
respect to the Second Time of Delivery, the obligation of the Underwriters to
purchase and of the Company to sell the Optional Shares) shall thereupon
terminate, without liability on the part of any non-defaulting Underwriter or
the Company, except for the expenses to be borne by the Company and the
Underwriters as provided in Section 6 hereof and the indemnity and contribution
agreements in Section 8 hereof; but nothing herein shall relieve a defaulting
Underwriter from liability for its default.

                 10.           The respective indemnities, agreements,
representations, warranties and other statements of the Company and the several
Underwriters, as set forth in this Agreement or made by or on behalf of them,
respectively, pursuant to this Agreement, shall remain in full force and
effect, regardless of any investigation (or any statement as to the results
thereof) made by or on behalf of any Underwriter or any controlling person of
any Underwriter, or the Company, or any officer or director or controlling
person of the Company, and shall survive delivery of and payment for the
Shares.

                 11.           If this Agreement shall be terminated pursuant
to Section 9 hereof, the Company shall not then be under any liability to any
Underwriter except as provided in Section 6 and Section 8 hereof, but, if for
any other reason any Shares are not delivered by or on behalf of the Company as
provided herein, the Company will reimburse the Underwriters through GSI for
all out-of-pocket expenses approved in writing by GSI, including fees and
disbursements of counsel, reasonably incurred by the Underwriters in making
preparations for the purchase, sale and delivery of the Shares not so
delivered, but the Company shall then be under no further liability to any
Underwriter in respect of the Shares not so delivered except as provided in
Sections 6 and 8 hereof.

                 12.           In all dealings hereunder, you shall act on
behalf of each of the Underwriters, and the parties hereto shall be entitled to
act and rely upon any statement, request, notice or agreement on behalf





                                      -6-
   7
of any Underwriter made or given by you jointly or by GSI on behalf of you as
the representatives of the Underwriters.

                                CERTIFICATE OF
            AMENDMENT TO THIRD RESTATED CERTIFICATE OF INCORPORATION
                                       OF
                               CIENA CORPORATION


It is hereby certified that:

         l.      The present name of the corporation is CIENA CORPORATION (the
"Corporation").  The Corporation was originally incorporated under the name
"Hyrdralite Incorporated", and the date of filing of the original Certificate
of Incorporation of the Corporation with the Secretary of State of the State of
Delaware is November 2, 1992.  A Restated Certificate of Incorporation was
filed thereafter on April 8, 1994 (the "First Restated Certificate"); a Second
Restated Certificate of Incorporation was filed thereafter on December 20, 1994
(the "Second Restated Certificate"); and a Third Restated Certificate of
Incorporation was filed thereafter on December 20, 1995 (the "Third Restated
Certificate").

         2.      The Third Restated Certificate is hereby amended to (i)
increase the authorized capital stock of the Corporation and effect a split up
outstanding shares of Common Stock, (ii) establish a classified Board of
Directors effective with the Corporation becoming a public company, with three
classes serving staggered three year terms, and each class consisting of two or
more directors, (iii) eliminate stockholder action by written consent, and (iv)
specify the terms under which a special meeting of stockholders may be called.

         3.      This amendment has been duly adopted by the stockholders of
the Corporation in accordance with the provisions of Sections 228 and 242 of 
the General Corporation Law of the State of Delaware.
   2
The first paragraph of Article FOURTH is hereby replaced in its entirety with
the following:

         The Corporation shall have the authority to issue two (2) classes of
shares to be designated respectively "Preferred Stock" and "Common Stock".  The
total number of shares of stock that the Corporation shall have the authority
to issue is Two Hundred Million (200,000,000) shares of capital stock, par
value $0.01 per share.  The total number of shares of Preferred Stock that the
Corporation shall have authority to issue is Twenty Million (20,000,000), par
value $0.01 per share.  The total number of shares of Common Stock which the
Corporation shall have the authority to issue is One Hundred Eighty Million
(180,000,000), par value $0.01 per share.  Effective with the filing of this
Amendment, each issued share of Common Stock of the Corporation, $0.01 par
value, shall be changed and reclassified into five shares of Common Stock,
$0.01 par value.

Articles SIXTH and SEVENTH of the Third Restated Certificate are hereby
replaced in their entirety with the following:

         SIXTH:  The following provisions are inserted for purposes of the
management of the business and conduct of the affairs of the Corporation and
for creating, defining, limiting and regulating the powers of the Corporation
and its directors and stockholders:

         (a)(l)  The number of directors shall initially be set at seven (7)
and, thereafter, shall be fixed from time to time exclusively by the Board of
Directors pursuant to a resolution adopted by a majority of the total number of
authorized directors (whether or not there exist any vacancies in previously
authorized directorships at the time any such resolution is presented to the
Board for adoption).  Prior to the effectiveness of the first registration
statement filed by the Company under the Securities Act of 1933, as amended,
the directors shall be elected at each annual meeting with a term to expire at
the next annual meeting of stockholders.  Upon the effectiveness of the first
registration statement filed under the Securities Act of 1933, as amended (the
"IPO Date"), the directors shall be divided into three classes consisting of
two or more directors each with the term of office of the first class (Class I)
to expire at the first annual meeting of stockholders following the IPO Date;
the term of office of the second class (Class II) to expire at the second
annual meeting following the IPO Date; the term of office of the third class
(Class III) to expire at the third annual meeting following the IPO Date; and
thereafter for each such term to expire at each third succeeding annual meeting
of stockholders after such election.  The initial allocation of existing
directors among the classes shall be made by
   3
determination of the Board of Directors.  Subject to the rights of the holders
of any series of Preferred Stock then outstanding, a vacancy resulting from the
removal of a director by the stockholders as provided in Article SIXTH, Section
C below may be filled at a special meeting of the stockholders held for that
purpose.  All directors shall hold office until the expiration of the term for
which elected, and until their respective successors are elected, except in the
case of the death, resignation, or removal of any director.

         (2)     Subject to the rights of the holders of any series of
Preferred Stock then outstanding, newly created directorships resulting from
any increase in the authorized number of directors or any vacancies in the
Board of Directors resulting from death, resignation or other cause (other than
removal from office by a vote of the stockholders) may be filled only by a
majority vote of the directors then in office, though less than a quorum, and
directors so chosen shall hold office for a term expiring at the next annual
meeting of stockholders at which the term of office of the class to which they
have been elected expires, and until their respective successors are elected,
except in the case of the death, resignation or removal of any director.  No
decrease in the number of directors constituting the Board of Directors shall
shorten the term of any incumbent director.

         (3)     Subject to the rights of the holders of any series of
Preferred Stock then outstanding, any directors, or the entire Board of
Directors, may be removed from office at any time, with or without cause, but
only by the affirmative vote of the holders of at least a majority of the
voting power of all of the then outstanding shares of capital stock of the
Corporation entitled to vote generally in the election of directors, voting
together as a single class.  Vacancies in the Board of Directors resulting from
such removal may be filled by a majority of the directors then in office,
though less than a quorum, or by the stockholders as provided in Article SIXTH,
Section (a)(1) above.  Directors so chosen shall hold office for a term
expiring at the next annual meeting of stockholders at which the term of office
of the class to which they have been elected expires, and until their
respective successors are elected, except in the case of the death, resignation
or removal of any director.

         (b)     The election of directors may be conducted in any manner
approved by the stockholders at the time when the election is held and need not
be by ballot.

         (c)     All corporate powers and authority of the Corporation (except
as at the time otherwise provided by law, by this Certificate of Incorporation,
as restated from time to time, or by the bylaws) shall be vested in and
exercised by the Board of Directors.

         (d)     From and after the IPO Date, any action required or permitted
to be taken by the stockholders of the Corporation must be effected at a duly
called
   4
annual or special meeting of stockholders of the Corporation and may not be
effected by any consent in writing by such stockholders.

         (e)     Special meetings of stockholders of the Corporation may be
called only (1) by the Board of Directors pursuant to a resolution adopted by a
majority of the total number of authorized directors (whether or not there
exist any vacancies in previously authorized directorships at the time any such
resolution is presented to the Board for adoption) or (2) by the holders of not
less than ten percent (10%) of all of the shares entitled to cast votes at the
meeting.

         (f)     The Board of Directors is expressly empowered to adopt, amend
or repeal bylaws of the Corporation.  Any adoption, amendment or repeal of
bylaws of the Corporation by the Board of Directors shall require the approval
of a majority of the total number of authorized directors (whether or not there
exist any vacancies in previously authorized directorships at the time any
resolution providing for adoption, amendment or repeal is presented to the
Board).  The stockholders shall also have power to adopt, amend or repeal the
bylaws of the Corporation.  Any adoption, amendment or repeal of bylaws of the
Corporation by the stockholders shall require, in addition to any vote of the
holders of any class or series of stock of the Corporation required by law or
by this Certificate of Incorporation, the affirmative vote of the holders of at
least sixty-six and two-thirds percent (66-2/3%) of the voting power of all of
the then outstanding shares of the capital stock of the Corporation entitled to
vote generally in the election of directors, voting together as a single class.

         SEVENTH:         The Corporation reserves the right to amend or repeal
any provision contained in this Certificate of Incorporation in the manner
prescribed by the laws of the State of Delaware and all rights conferred upon
stockholders are granted subject to this reservation; provided, however, that,
notwithstanding any other provision of law which might otherwise permit a
lesser vote or no vote, but in addition to any vote required by law or by this
Certificate of Incorporation, the affirmative vote of the holders of at least
66-2/3% of the voting power of all of the then outstanding shares of the
capital stock of the Corporation entitled to vote generally in the election of
directors, voting together as a single class, shall be required to amend or
repeal Articles SIXTH, SEVENTH, EIGHTH and NINTH.

the signatures thereon are their act and deed and that the facts stated herein

Voting Rights:

(I) Each holder of shares of Convertible Preferred Stock shall be entitled to
vote on all matters and, except as otherwise expressly provided herein, shall
be entitled to the number of votes equal to the largest whole number of shares
of Common Stock into which such shares of Convertible Preferred Stock could be
converted, pursuant to the provisions of paragraph (d) hereof, on the record
date for the determination of the stockholders entitled to vote on such matters
or, if no such record date is established, in accordance with Delaware law.

(ii)  Each holder of shares of Common Stock shall be entitled to one vote for
each share of Convertible Preferred Stock held and no holder of Convertible
Preferred Stock shall be entitled to cumulate its votes by giving one candidate
more than one vote per share.  These special and exclusive voting rights of the
holders of Convertible Preferred Stock contained in this subparagraph (iii) may
be exercised either at a special meeting of the holders  of Convertible
Preferred Stock called as provided below, or at any annual or special meeting
of the stockholders of the Corporation, or by written consent of such holders
in lieu of a meeting.  The directors to be elected pursuant to this
subparagraph (iii) shall serve for a term extending from the date of their
election and qualification and until the time of the next succeeding annual
meeting of stockholders and until their successors have been duly elected and
qualified.

If at any time any directorship to be filled by the holders of the Convertible
Preferred Stock pursuant to this subparagraph (iii) becomes vacant, the
secretary of the Corporation shall, upon the written request of the holders of
record of shares representing at least 25% of the voting  power of Convertible
Preferred Stock then outstanding, call a special meeting of the holders of the
Convertible Preferred Stock for the purpose of electing a director to fill such
vacancy.  Such meeting shall be held at the earliest practicable date at such
place as is specified in the By-Laws of the Corporation.  If such meeting shall
not be called by the Secretary of the Corporation within ten days after
personal service of said written request upon him or her, then the holders of
record shares representing at least 25% of the voting power of the Convertible
Preferred Stock then outstanding may designate in writing one of their number
to call such meeting at the expense of the Corporation, and such meeting may be
called by such persons so designated upon the notice required for annual
meetings of stockholders and shall be held at such specified place.  Any holder
of Convertible Preferred stock so designated shall have access to the stock
books of the Corporation for the purpose of calling a meeting of the
stockholders pursuant to these provisions.
   4
At any meeting held for the purpose of electing directors at which the holders
of the Convertible Preferred stock shall have the special and exclusive rights
to elect directors as provided in the subparagraph (iii), the presence, in
person or by proxy, of the holders of record of shares representing a majority
of the voting power of the Convertible Preferred Stock then outstanding shall
be required to constitute a quorum of the Convertible Preferred Stock for such
election.  In the absence of such a quorum, the holders of record of shares
representing a majority of the voting power of the Convertible preferred Stock
present, in person or by proxy, shall have the power to adjourn the meeting for
the election of directors through no notice other than announcement at the
meeting.

A vacancy in any directorship to be elected by the holders of the Convertible
Preferred Stock pursuant to this subparagraph (iii), may be filled only by (a)
vote of the holders of a majority in holding power of the Convertible Preferred
Stock, acting  separately as one class, or (b) written consent in lieu of a
meeting the holders of a majority in voting power of the Convertible Preferred
Stock, acting separately as one class.

Any director elected pursuant to this subparagraph (iii) may be removed after
the aforesaid term of office, either with or without cause, by, and only by,
the affirmative vote of the holders of the Convertible  Preferred stock given
either at a special meeting of such stockholders duly called for that purpose
or pursuant to a written consent of such stockholders.

(b)  Dividend Rights.  (I)  Each issued and outstanding share of Convertible
Preferred Stock shall entitle the  holder of record thereof to receive, when,
as and if declared by the Board of Directors, out of any funds legally
available therefor,  dividends in cash at the annual rate per share of (A)  Six
Cents ($0.06) for Series A Preferred Stock, (B) Twelve and Seventy Five One
Hundredths Cents ($0.1275) for Series B Preferred Stock and (C) Fifty-Six Cents
($0.56) for Series C Preferred Stock (or such greater amount per share as such
Convertible Preferred stock would be entitled to receive if such Convertible
Preferred Stock were converted to Common Stock), as adjusted for stock splits,
stock dividends, recapitalizations, reclassifications and similar events
(together herein referred to as "Recapitalization Events"),  payable as the
Board of Directors may from time to time determine.  Dividends and distribution
( other than those paid solely in Common Stock or Preferred stock other than
Convertible Preferred Stock respectively) may be paid, or declared and set
aside for payment, upon shares of Common stock or Preferred Stock other than
Convertible Preferred Stock in any calendar year only if dividends shall have
been paid, or declared and set aside for payment, on account of all shares of
Convertible Preferred Stock then issued and outstanding, at the aforesaid rate
for the calendar year.  Except as herein set forth, the Board of Directors of
the Corporation is under no obligation to pay dividends and the dividend
preferences granted herein to shares of Convertible Preferred Stock shall apply
only at such time as the Board of Directors may in its discretion decide to pay
or declare and set aside for payment of any dividends on any shares of capital
stock of the Corporation.
   5
(ii)  Until December 1, 2001, the right to dividend upon the issued and
outstanding shares of Convertible preferred Stock shall be non-cumulative and
shall not be deemed to accrue, whether dividends are earned or whether there be
funds legally available therefor, unless and until said dividends shall have
been declared by the Board of Directors.  If until December 1, 2001, the
Corporation pays dividends upon the Convertible Preferred stock that are less
than the dividend preference on the Convertible Preferred Stock pursuant to the
subsection (b) (I) hereof, dividends shall be distributed ratably among the
holders of Convertible Preferred stock based upon the amounts of their
respective dividend preferences.

(iii)  From and after December 1, 2001, the right to dividends among the issued
and outstanding shares of Convertible Preferred Stock shall be cumulative so
that such rights shall be deemed to accrue, on a quarterly basis, from and
after December 1, 2001, whether earned, or whether there be funds legally
available therefor, or whether said dividends shall have been declared .  If
such dividends in respect of any period beginning December 1, 2001, shall not
have been declared and either paid or a sum sufficient for the payment thereof
set aside in full, the deficiency shall first be fully paid on the Convertible
Preferred Stock, before any dividend or other distribution ( other than those
payable solely in Common Stock or Preferred Stock other than Convertible
Preferred Stock, respectively) may be paid or declared on shares of Common
Stock or Preferred Stock other than Convertible Preferred Stock.  Any accrued
and unpaid dividends on the Convertible Preferred stock shall in any event be
paid upon conversion of the Convertible Preferred stock, in cash or in Common
stock at its then fair market value, as determined in good faith by the Board
of Directors of the Corporation.  If at any time from and after December 1,
2001, the Corporation pays dividends upon the Convertible Preferred Stock that
are less than the total dividends then accrued but unpaid for the Convertible
Preferred stock, such dividends shall be distributed ratably among the holders
of Convertible Preferred Stock based upon the aggregate accrued but unpaid
dividends on the shares of Convertible Preferred Stock held by each such
holder.  Any accumulation of dividends on the shares of Convertible Preferred
stock shall not bear interest.

(iv)  The restrictions on dividends and distributions with respect to shares of
Common Stock and of Preferred stock other than Convertible Preferred Stock set
forth in this paragraph (b) are in addition to, and not in derogation of, the
other restrictions on such dividends and distributions set forth herein.

(c)  Liquidation Rights.  (I)  In the event of a voluntary or involuntary
liquidation, dissolution, or winding up of the Corporation (a "Liquidation"),
the holders of record of share of the Series C Preferred Stock shall be
entitled to receive, prior and in preference to any distribution of any assets
of the Corporation to the holders of Common Stock or any Preferred Stock other
than Series C Preferred stock by reason of their ownership thereof, out of the
assets of the Corporation legally available therefor, Seven Dollars ($7.00) per
share of Series C Preferred Stock ("The Original Series C Issue Price"), as
adjusted for recapitalization events pursuant to subsections (d) (iv)  (B) (F),
as appropriate, plus a further amount per share equal to dividends, if any, (A)
then declared
   6
and unpaid on account of shares of Series C Preferred Stock and (B) whether or
not declared, then accrued in accordance with the provisions of subparagraph
(b) (iii) hereof, before any payment shall be made or any assets distributed to
the holders of Common or any Preferred stock other than Series C Preferred
Stock.  If upon any liquidation, the assets available for distribution among
the holders of the Series C Preferred Stock shall be insufficient to permit
payment to such holders of the full preferential amounts aforesaid, then such
assets shall be distributed ratably among the holders of Series C Preferred
Stock.

permit the payment to the holders of Series C Preferred Stock of an amount in
excess of Seven Dollars ($7.00) per share of Series C Preferred Stock ( as

have conversion rights ("The Conversion Rights") as follows:

(I)  Right to Convert.   Each holder of record of shares of Convertible
Preferred stock may, at any time, upon surrender to the Corporation of the
Certificates therefor at the principal office of the Corporation or at such
other place as the Corporation shall designate, convert all or any part of such
holder's shares of Convertible Preferred Stock into such number of fully paid
and non-assessable shares of Common Stock of the Corporation (as such Common
Stock shall then be constituted) equal to the product of (A) the number of
shares of Convertible Preferred Stock which such holder shall then surrender to
the Corporation, multiplied by (B) the number determined by dividing (1) One
Dollar ($1.00) for Series A Preferred Stock, One Dollar and Fifty Cents ($1.50)
for Series B Preferred Stock and Seven Dollars ($7.00) for Series C Preferred
Stock by (2) the Conversion Price (as hereinafter defined) per share for the
respective series of Convertible Preferred Stock in effect at the time of
conversion.  Promptly following surrender of such certificates, the holder
shall be entitled to receive certificates evidencing the number of shares of
Common Stock into which such shares of Convertible Preferred Stock are
converted.


(ii)  Automatic Conversion.

(A) All outstanding shares of Convertible Preferred Stock shall be deemed
automatically  converted into such number of shares of Common Stock as are
determined in accordance with subparagraph (d) (I) hereof upon (1) the
consummation of a firm commitment underwritten public offering of the
securities of the Corporation pursuant to a registration statement filed with
the Securities and Exchange Commission pursuant to the Securities Act of 1933,
as amended, where the aggregate proceeds to the Corporation resulting from the
sale of such securities (before deduction of underwriting discounts and
expenses of sale) is not less than $15,000,000 and the per share sales price of
such securities before such deductions is not less than Twelve Dollars
($12.00), as adjusted for Recapitalization Events, or (2) the affirmative vote
of the holders of record of (a) sixty-seven percent(67%) in interest of the
outstanding shares of Convertible Preferred Stock, voting together as one class
to that effect, and (b) eighty-five percent (85% in interest of the
   9
outstanding shares of Series C Preferred Stock voting separately as a class
(either such event being hereinafter referred to as an "Automatic Conversion
Event").

(B)  In addition to the Automatic Conversion Event set forth in subsection (9A)
above, if any holder of Convertible Preferred stock or holder of a warrant,
option or other right to acquire Convertible Preferred Stock (either such
holder being hereinafter referred to as a "Holder") ( by itself or together
with affiliated persons or entities which affiliation shall include (1) any
venture fund related to a Holder by virtue of having at least two (2) common
individuals who are officers, employees, directors, or partners of the entities
that are general partners or managers of such venture funds or (2) any partner
of such venture fund; any such person or entity, hereinafter an 'Affiliate")
fails to [participate in any particular financing by the Corporation consisting
of a bridge loan for a term not in excess of one year or the offering of
Convertible Securities (as herein defined) (an "Additional Offering"), by
acquiring in such Additional Offering  such portion of the principal amount of
the financing or such number of shares as shall equal the product of the
principal amount of the bridge loan or the number of shares actually offered in
the Additional Offering to all Holders, multiplied by a fraction:  (x) the
numerator of which is the number of shares of Convertible Preferred Stock of
each series held by such Holder ( by itself or together with any Affiliate),
which number shall include the number of shares of Convertible Preferred Stock
issuable to such holder upon exercise of any warrants held by such holder that
are exercisable for shares of Convertible Preferred Stock ( "Warrant Shares") ,
at the time of such Additional  Offering, and (y) the denominator of which is
the total number of shares of the Convertible Preferred Stock of each series
then outstanding, including all Warrant Shares, in each case determined on the
basis of the number of shares of Common Stock into which such shares of
Convertible Preferred Stock would be convertible at the Conversion Price for
such shares of Convertible Preferred stock that would be in effect immediately
after the transaction ( the "Converted Shares"), assuming all Holders purchased
their respective pro rata shares in such transaction or participated in the
bridge loan financing ("the Pro Rata Share"), then to the extent of the
percentage of the Pro Rata Share not so acquired by the Holder ( or by an
Affiliate of such Holder) ("Refused Percentage) the number of outstanding
shares of such Holder's Convertible Preferred Stock including for this purpose
all warrant Shares) determined by multiplying the Refused Percentage by all
outstanding shares of such Holder's Convertible Preferred Stock ( including for
this purpose all warrant Shares) ("Converted Percentage")  shall be
automatically converted into such number of fully paid and non-assessable
shares of Common Stock of the Corporation (as such Common Stock shall then be
constituted) equal to the product of (x) the Converted Shares multiplied by (y)
the number determined by dividing (1) One dollar ($1.00) for Series A Preferred
Stock, One Dollar and Fifty Cents ($1.50) for Series B Preferred stock and
Seven Dollars ($7.00) for Series C Preferred stock by (2) the Initial
Conversion Price (as defined) (subject to adjustments as provided in
subsections (d) (iv) (B) - (F), but without giving any effect to adjustments
pursuant to subsection (d) (iv) (A) per share for the Convertible Preferred
Stock (such event being hereinafter referred to as an "Additional Automatic
Conversion Event");  provided, however, that the number of shares to be offered
in the Additional Offering to all Holders shall be determined in good faith by
the
   10
Board of Directors and, if the Additional Offering consists of bridge notes
convertible into securities or Convertible Securities at an Effective Price
greater than $1.00 per share for Series A Preferred Stock, $1.50 per share for
Series B Preferred Stock, or $7.00 per share for Series C Preferred Stock (as
adjusted for Recapitalization Events), the Additional Offering shall be
required, in the reasonable business judgment of the Board of Directors, as a
condition to the Corporation's ability to secure financing from one or more
third parties.  Notwithstanding the foregoing, the term  "Additional Automatic
Conversion Event" shall not include any "Deferred Closing" under Section 2.3 of
that certain Preferred stock Purchase Agreement relating to the Series B
Preferred Stock dated as of December 22, 1994 or any failure to participate in
a financing when pursuant to a written request by the Company, the holder of
shares of Convertible Preferred Stock agrees in writing to waive such holder's
right of first refusal with respect to such financing.

(C)  On or after the date of occurrence of an Automatic Conversion Event or an
Additional Automatic Conversion Event, and in any event within 10 days after
receipt of notice, by mail, postage prepaid from the Corporation of the
occurrence of such Event, each holder of record of shares of Convertible
Preferred Stock Subject to such event shall surrender such Holder's
certificates evidencing such holder's shares of Convertible Preferred Stock at
the principal office of the Corporation at such other place as the Corporation
shall designate, and shall thereupon be entitled to receive certificate
evidencing the number of shares of Common Stock into which such shares of
Convertible Preferred Stock are converted.  On the date of the occurrence of an
Automatic Conversion Event or an Additional Automatic Conversion Event, each
Holder of record of shares of Convertible Preferred Stock subject to such event
shall be deemed to be the holder of record of the Common Stock issuable upon
such conversion, notwithstanding that the certificate representing such shares
of convertible Preferred Stock shall not have been surrendered at the office of
the Corporation, that notice from the Corporation shall not have been received
by any holder of record of shares of Convertible Preferred Stock, or that the
certificate evidencing such shares of common stock shall not then be actually
delivered to such holder.

Series A Issue Price.  The Initial Conversion Price per share for shares of
Series B Preferred Stock shall be the Original Series B Issue Price.  The
initial Conversion Price per share for shares of Series C Preferred Stock shall
be the Original Series C Issue Price.  The Conversion Price shall be subject to

deemed to have been received by the Corporation for such issue under
subparagraph (d) (iv) (A)."

each series of Convertible Preferred Stock."

Corporation issues or sells, or is deemed by the express provisions of this
subparagraph (d) (iv) (A) to have issued or sold, Additional Shares of Common
Stock, for an Effective Price less than the
   12
Initial Conversion Price (as adjusted for Recapitalization  events)  of any
series of Preferred Stock, then and in each such case the then existing
Conversion Price for such series of Convertible Preferred Stock shall be
reduced, as of the opening of business on the date of such issue or sale, to
the effective price of such issuance or sale.

(2)  For the purpose of making any adjustment required under thus subparagraph
(d) (iv) (A), the consideration received by the Corporation for any issue or
sale of securities shall (a) to the extent it consists of cash be computed at
the gross amount of cash received by the Corporation before deduction of any
expenses payable by the Corporation and any underwriting or similar
commissions, compensation or concessions paid or allowed by the Corporation in
connection with such issue or sale, (b) to the extent it consists of property
other than cash, be computed at the fair market value of that property as
determined in good faith by the Board of Directors and (c) if Additional Shares
of Common Stock, Convertible Securities or rights or options to purchase either
additional shares of Common Stock or Convertible Securities are issued or sold
together with other stock or securities or other assets of the Corporation for
a consideration which covers both, be computed (as provided in clauses (a) and
(b) above) as the portion of the consideration so received that may be
reasonably determined in good faith by the Board of directors to be allocable
to such Additional Shares of Common Stock, Convertible Securities or rights or
options.

(3)  For the purpose of the adjustment required under the subparagraph (d) (iv)
(A), if at any time or from time to time after the Issuance Date for any series
of Convertible Preferred stock, the Corporation issues or sells any Options or
Convertible Securities, or increases the number of shares of Common Stock for
which any option may be exercised or into which any Convertible Securities may
convert (other than options or rights exercisable for or convertible into
shares of common stock referred to in clause (BB) of the definition  of
Additional Shares of Common Stock), then in each case the Corporation shall be
deemed to have issued at the time of the issuance of such Options or
Convertible Securities, or at the time of the increase in the number of shares
of Common Stock for which such Options or Convertible Securities may be
exercised, the  maximum number of additional shares of common Stock ( as set
forth in the instruments relating thereto, giving effect to any provision
contained therein for a subsequent upward adjustment of such number)  issuable
upon exercise or conversion thereof and to have received as consideration for
the issuance of such shares an amount equal to the total amount of the
consideration, if any, received by the Corporation for the issuance of such
Options or Convertible securities, or for the increase in the number of shares
of Common Stock for which such Options or Common Stock may be exercised plus,
in the case off such Options, the minimum amounts of consideration, if any ( as
set forth in the instruments relating thereto, giving effect to any provision
contained therein for a subsequent downward adjustment of such consideration),
payable to the Corporation upon the exercise  of such Options and , in the case
of Convertible Securities, the minimum amounts of consideration, if any,
payable to the Corporation ( other than by cancellation of liabilities or
obligations evidenced by such Convertible securities which were deemed to have
been received by the Corporation on issuance of such convertible Securities.
No
   13
further adjustment of the Conversion Price, adjusted upon the issuance of such
Options or Convertible securities, shall be made as a result of the actual
issuance of Additional Shares of common stock on the exercise of any such
Options or the conversion of any such Convertible securities; provided,
however, that if any such Options or the conversion privilege represented by
any such Convertible Securities shall expire without having been exercised, or
are exercised for a lesser number of Additional Shares of Common Stock or with
a greater consideration paid to the Corporation than was previously deemed to
be issued or received by the Corporation, the Conversion Price adjusted upon
the issuance of such options or Convertible Securities ( or an increase in the
number of shares of Common Stock for which they may be exercised) shall be
readjusted to the Conversion Price which would have been in effect had an
adjustment been made on the basis that the only Additional Shares of Common
Stock so issued were the Additional Shares o common Stock, if any, actually
issued or sold on the exercise of such Options or rights of conversion of such
convertible Securities, and such Additional Shares of Common Stock, if any,
were issued or sold for the consideration actually received by the Corporation
upon such exercise, plus consideration, if any, actually received by the
Corporation for the granting of all such Options, whether or not exercised,
plus the consideration received for issuing or selling the Convertible
Securities actually converted plus the consideration, if any, actually received
by the Corporation ( other than by cancellation of liabilities or obligations
evidenced by such Convertible Securities which were deemed to have been
received by the Corporation on issuance of such Convertible Securities) on the
conversion of such Convertible Securities; and provided further, however, that
if any such Options or Convertible securities by their terms provide, with the
passage of time or otherwise, for any increase or decrease in the consideration
payable to the Corporation, or decrease or increase in the number of shares of
Common Stock or Convertible Securities issuable, upon the exercise, conversion,
or exchange thereof, the Conversion Price for each series of Convertible
Preferred Stock computed upon the original issue thereof ( or upon the
occurrence of a record date with respect thereto), and any subsequent
adjustments based thereon, shall, upon any such increase or decrease becoming
effective, be recomputed to reflect such increase or decrease insofar as it
affects such Options or the rights of conversion or exchange under such
Convertible securities (provided, however, that no such adjustment of the
Conversion price for a series of  Convertible Preferred Stock shall affect
Common Stock previously issued upon conversion of such series of Convertible
Preferred Stock).

(4)  In each case of an adjustment or readjustment of the Conversion Price or
the number of shares of Common Stock or other securities issuable upon
conversion expense, shall cause the  chief financial officer of the Corporation
to compute such adjustment or readjustment in accordance with the provisions
hereof and prepare a certificate showing such adjustment or readjustment , and
shall mail such certificate, by first class mail, postage prepaid, to each
registered holder of Convertible Preferred Stock at the holder's address as
shown in the Corporation's books.  The certificate shall et forth such
adjustment or readjustment, showing in detail the facts upon which such
adjustment or readjustment is based, including a statement of (a) the
consideration received or deemed to be received by the Corporation for any
Additional Shares of Common Stock issued or
   14
sold or deemed to have been issued or sold, (b) the Conversion Price for each
series of Convertible Preferred Stock at the time in effect, (c) the number of
Additional Shares of Common Stock and (d) the type and amount, if any, of other
property which at the time would be received upon conversion of such

he Corporation is less than the Conversion Price in effect on the date of, and
immediately prior to, such issue, for such share of Convertible Preferred
stock.

(b)  Adjustment for Stock Splits and Combinations.
If the Corporation at any time or from time to time after the Issuance Date
effects a subdivision of the outstanding Common Stock, the Conversion Price for
each series of convertible preferred Stock then in effect immediately before
that subdivision shall be proportionately decreased, and conversely, if the
Corporation at any time or from time to time after the Issuance Date combines
the outstanding shares of Common Stock, the Conversion Price for each series of
Convertible Preferred Stock then in effect immediately before the combination
shall be proportionately increased.  Any adjustment under this subparagraph (d)
(iv) (B) shall become effective at the close of business on the date of the
subdivision or combination becomes effective.

(C)  Adjustment for Certain Dividends and Distributions.
In the event the Corporation at any time, or form time to time after the
Issuance Date makes, or fixes a record date for the determination of holders of
Common Stock entitled to  receive, a dividend or other distribution payable in
Additional Shares of Common Stock or in any right to acquire Common Stock for
no consideration, then and in each such event the Conversion Price for each
series of Convertible Preferred Stock then in effect shall be decreased as of
the time of such issuance or, in the event such a record date is fixed, as of
the close of business on such record date, by multiplying the Conversion Price
for the series of Convertible Preferred Stock then in effect by a fraction (a)
the numerator of which is the total number of shares of Common Stock issued and
outstanding immediately prior to the time of such issuance or the close of
business on such record date, and (b) the denominator of which shall be the
total number of shares of Common Stock issued and outstanding immediately
prior to the time of such issuance or the close of business on such record date
plus the number of shares of Common Stock issuable in payment of such dividend
or distribution; provided however, that if such record date is fixed and such
dividend is not fully paid or if such distribution is not made on the date so
fixed, the Conversion Price for each such series of Convertible Preferred Stock
shall be recomputed accordingly as of the close of business on such record date
and thereafter the Conversion Price for each series of Convertible Preferred
Stock shall be adjusted pursuant to this subparagraph (d) (iv) (C) as of the
time of actual payment of such dividends or distributions.
   15
(D)  Adjustment for other Dividends and Distributions.
In the event that the Corporation at ant time or form time to time after the
Issuance Date makes, or fixes a record date for the determination of holders of
Common Stock entitled to receive, a dividend or other distribution payable in
securities to the Corporation other than shares of Common Stock, then in each
such event provision shall be made so that the holder of Convertible Preferred
Stock shall receive upon conversion thereof, in addition to the number of
shares of Common Stock receivable thereupon, the amount of securities of the
Corporation which they would have received had their Convertible Preferred
stock been converted into Common Stock on the date of such event and had they
thereafter, during the period from the date of such event and including the
date of conversion retained such securities receivable by them as aforesaid
during such period, subject to all other adjustments called for during such
period under this paragraph (d) with respect to the rights of the holders of
the Convertible Preferred Stock.

(E)  Adjustment for Reclassification, Exchange and Substitution.
If the Common Stock Issuable upon the conversion of Convertible Preferred Stock
is changed into the same or a different number of share of any other class or
classes of stock, whether by recapitalization, reclassificatioon or  otherwise
( other than a subdivision or combination of shares, or stock dividend or a
recapitalization, reclassification or otherwise,  ( otheer than a subdivision
or combination of shares, or stock dividend or a recapitalization provided for
elsewhere in this paragraph (d)), then and in any such event each holder of
Convertible Preferred Stock shall have the rioght thereafter to convert such
stock into the kind and amount of stock and other securities and property
receivable upon such recapitalization, reclassification  or other change, by
holders of the number of shares of Common Stock into which such shares of
Convertible oreferred stock would have been converted immeediately prior to
such recapitalization, reclassification  or change, all subject to further
adjustment as provided herein.

(F) Reorganizations.
If at any time or form time to time there is a capital reorganization of the
Common Stock ( other than a recapitalization, subdivision, combination,
reclassification or exchange of shares provided for elsewhere in this paragraph
(d)), then, aas a part of such reorganization, provision shall be made so that
the holders of Convertible Preferred Stock shall thereafter be entitled to
receive upon conversion of Preferred Stock, the number of shares of stock or
otheeer securities or property of the Corporation to which a holder of Common
Stock deliverable upon conversion would have been entitled on such capital
roerganization.  In any such case, appropriate adjustment shall be made in the
application of the provisions of this paragraph (d) with respect to the right s
of the holders of the Convertible Preferred Stock after the reorganization to
the end that the provision of this paragraph (d) ( including adjustment of the
Conversion Price for each series of Convertible Preferred stock then in effect
and number osf shares purchaaseable upon conversion of Convertible preferred
Stock) shall be applicable after that event and be as nearly equivalent to the
provisions hereof as may be practicable.

   17
account of the respective series of Convertible Preferred stock and (2) whether
or not declared, then accrued on the respective series of Convertible Preferred
stock in accordance with the provisions of subparagraph (b) (iii) hereof to and
including the date fixed for redemption( the "Redemption Price").  The
Redemption Price for each series of Convertible Preferred Stock shall be
applicable both to elective and mandatory redemptions pursuant to the
provisions of this section.  The fair market value of the Convertible Preferred
Stock shall be determined as follows:  The Board of Directors shall determine
the fair market value of each share of each series of convertible Preferred
Stock;  provided, however, that (A) if the board of Directors determines that
the fair market value of each share of (1) series A Preferred stock is greater
than One Dollar ($1.00), (2) Series B Preferred Stock is greater than One
Dollar and Fifty Cents ($1.50) or (3) Series C Preferred Stock is greater than
Seven Dollars ($7.00) ( adjusted for any recapitalization eveents with respect
to such shares) , the Corporation shall promptly give the stockholders notice
thereof and the holders of a majority of the Corporation's then outstanding
Common Stock shall have the right to contest any of these determinations, or
both if applicable, by giving notice thereof to the Corporation within fifteen
(15) days of the receipt of the Corporation's notice, and in such event the
fair market value of the respective series of Convertible Preferred Stock shall
be determined by an independent appraiser paid by the Corporation and mutually
acceptable to the Corporation, the holders of a majority of the Common Stock
and the holders of a majority of the then outstandingConvertible Preferred
stock of the respective sseries to which such appraisal relates, or (B) if the
holders of a majority of the then outstanding shares of such series of
Convertible Preferred stock contests the determination of the Board of
Directors, then the fair market value of such series of Convertible Preferred
Stock shall be determined by an independent appraiser mutually acceptable to a
majority of disinterested directors and holders of a majority of the then
outstanding shares of such series of Convertible Preferred Stock. In the event
that the holders of a majority of the shares of a series of Convertible
Preferred Stock contest the board of directors fair market value determination,
the cost of appraisal shall be borne as follows:

(A) if the fair market value determined by the independent appraiser is less or
equal to ninety percent (90%) of the fair market value as determined by the
Board of Directors, then the cost of appraisal shall be borne by the holders of
the respective sseries of Convertible Preferred Stock pro rata based on the
number of shares held;

(B)  if the fair market value determined by the appraiser is equal to or
greater than one hundred and ten percent (110%) of the fair market value as
determined by the Board of Directors, the cost of appraisal shall be borne by
the Corporation; and

(C)  if the fair market value as determined by the independent appraiser is
between ninety and one-hundred and ten percent (90 - 110%) of the fair market
value as determined by the Board ofDirectors, then the cost of appraisal shall
be borne 50% by the Corporation and 50% by the holders of the respective series
of Convertible Preferred Stock, with each holder paying a pro rata portion of
such cost based on the number of shares held.
   18
(iii)  Mandatory Redemption;  Two Installments.
The Redemption Election constitutes an election in favor of a mandatory
redemption of all shares of Convertible Preferred Stock.  Each of Series A,
Series B and Series C Preferred Stock shall be redeemed in two equal
installments, with the Corporation redeeming 50% of each holder's shares of
each such series of Convertible Preferred Stock in the first installment and
the remaining shares of each such series of Convertible Preferred stock in the
second installment.  Subject to the Corporation having funds legally available,
the closing of the first installment with respect to each of Series A, Series B
and Series C shall occur on or about the seventh anniversary of the initial
issuance of the respective series of Convertible Preferred stock (with respect
to each series, the "Firest Redemption date") and the closing of the second
installment shall take place on or about the eighth anniversary of the initial
issuance of the respective series of Convertible Preferred Stock ( with respect
to each series, the "Second Redemption Date").  If the Corporation shall not
have sufficient funds legally available for redeeming Convertible Preferred
Stock at the First Redemption Date or the Second Redemption Date of any series,
respectively, the Corporation sghall redeem a pro rata portion of each holder's
shares of such series of Convertible Preferred Stock out of the funds legally
available therefor and shall redeem the remaining shares to have been redeemed
in such installment as soon as practicable after the Corporation has funds
legally available therefor.  If after either the  First Redemtion Date or the
Second Redemption Date of any series of Convertible Preferred Stock, any shares
of such series of Convertible Preferred Stock are outstanding that the
Corporation was required to redeem on such Redemption Date (the "Delayed
Redemption Shares"), the Corporation shall not pat dividends or other
distributions or make any other payments on Common Stock or any Preferred Stock
other than the series of Convertible Preferred Stock of which the delayed
redemption shares are a pert until the Delayed Redemption Shares have been
redeemed for the Redemption Price.

(iv)  Redemption Notice.
If the Redemption Election has been received, the Corporation shall mail,
postage prepaid, not less than thirty (30) days nor more than sixty (60) days
prior to the  First and Second Redemption Dates, written notice thereof (the
"Redemption Notice") , to each holder of record of the Convertible Preferred
Stock, at its post office address last shown on the records of the
Corporation.Each such Redemption Notice shall state:

(A)  The number of shares of Convertible Preferred Stock held by the holder
that th e Corporation shall redeem on the Redemption Date specified in the
Redemption Notice;

(B)  The Redemption Date and Redemption Price;

(C)  The date upon which the holder's conversion rights ( as set forth in
paragraph (d) above) as to such shares terminate, which termination shall be
five days before the Redemption Date;  and
   19
(D)  That the holder is to surrender to the Corporation, in the manner and at
the place designated, its certificate or certificates representing the shares
of Convertible Preferred Stock to be redeemed.

(v)  Surrender of Certificates;  Payment.
On or before each Redemption Date, each holder of shares of Convertible
Preferred Stock to be redeemed on such Redemption Date, unless such holder has
exercised its right to convert the shares aas provided in paragraph (d)
hereeof, shall surrender the certificate or certificates representing such
shares to the Corporation, in the manner and at hre place designated in the
Redemption Notice, and thereupon the Redemption Price for such shares shall be
payable to the order of the person whose name appears on such certificate or
certificates as the owner thereof, and each surrendered certificate shall be
cancelled and retired.  In the event that fewer than all the shares represented
by such certificate are redeemed, a new certificate representing them shall be
issued forthwith.

(vi)  Rights Subsequent to Redemption.
If the Redemption Notice shall have been duly given, and if on each Redemption
Date the Redemption Price thereafter is either paid or made available for
payment throughthe deposit arrangement specified in subparagraph (vii) below,
then notwithstanding the certificates evidencing any of the shares of
Convertible Preferred Stock so called for redemption shall not have been
surrendered, the dividends with respect to such shares shall cease to accrue
after the Redemption Date and all rights with respect to such shares shall
forthwith terminate after the Redemption Date, except only the right of the
holders to receive the redemption Price without interest upon their surrender
of their certificate or certificates therefor.

(vii)  Deposit of Funds.
On or prior to each Redemption Date, the Corporation shall deposit as a trust
company, having a capital and surplus of at least $100,000,000, a sum equal to
the aggregate Redemption Price of all shares of Preferred stock called for
redemption on such Redemption Date and not yet redeemed or converted, with
irrevocable instructions and authority to the bank or trust company to pay, on
and after each such Redemption Date, the Redemption Price to the respective
holders upon the surrender of their share certificates.   From and after the
date of such deposit (but not prior to each Redemption Date), the shares so
called for redemption on such Redemption Date shall be redeemed.  The deposit
shall constitute full payment of the shares of their holders, and from and after
each Redemption Date the shares redeemed on such Redemption Date shall be
deemed to be no longer outstanding, and the holders thereof shall cease to be
stockholders with respect to such shares and shall have no rights with respect
thereto except the rights to receive, from the bank or trust company, payment
of the Redemption Price of the shares, without interest, upon surrender of their
certificates therefor.  Any funds so deposited and unclaimed at the end of
one year from the Second Redemption Date shall be released or repaid to the
Corporation, after which the holders of shares called for redemption shall be
entitled to receive payment of the Redemption Price only from the Corporation.

(f)  Protective Provisions.  So long as any shares of any series of Convertible
Preferred Stock are outstanding and subject to any additional voting rights 
required by applicable law, the Corporation shall not, without the affirmative 
vote of the holders of record of sixty-seven percent (67%) of the outstanding 
shares of each of Series A Preferred Stock, Series B Preferred Stock and Series
C Preferred Stock, each series voting separately as a class:


(i)   Amend, repeal or modify any provision of, or add any provision to, the 
Corporation's Certificate of Incorporation or By-Laws if such action would

restrictions provided for the benefit of, such series of Convertible Preferred
Stock so as to affect such series of Convertible Preferred Stock adversely;
 
(ii)  Authorize, create or issue any additional shares of such series of 
Convertible Preferred Stock, or authorize or create shares of any class or
series of stock having any preference or priority as to dividends, redemption or
assets superior to or on a parity with any such preference or priority of such

into or exchangeable for, or having optional rights to purchase, any shares of
the Corporation having any such preference or priority; 



(iii) Reclassify the shares of Common Stock or any Preferred Stock other than 
the Convertible Preferred Stock as to dividends, redemption or assets into 
shares of such series of Convertible Preferred Stock or into shares having any 
preference or priority as to dividends or assets
   20
superior to or on a parity with that of such series of Convertible Preferred 
Stock;

(iv)  Set aside or apply any monies for the purchase, redemption, retirement, 
or other acquisition or liquidation of the shares of Common Stock or any 
Preferred Stock other than the Convertible Preferred Stock; or

(v)  Increase the number of members of the Board of Directors without a 
proportional increase in the number of members to be elected exclusively by the
Convertible Preferred Stock as provided in subparagraph (a) (iii) (any fraction
rounded up to increase the number of members elected exclusively by the
Convertible Preferred Stock).

SIXTH:  The following provisions are inserted for purposes of the management 
of the business and conduct of the affairs of the Corporation and for creating,
defining, limiting and regulating the powers of the Corporation and its 
directors and stockholders:

(a)  The number of directors of the Corporation shall be fixed and may be 
altered from time to time in the manner provided in the By-Laws, and vacancies 
in the Board of Directors and newly created directorships resulting from any 
increase in the authorized number of directors may be filled, and directors 
may be removed, as provided in the By-Laws and this Third Restated
Certificate of Incorporation.

(b)  The election of directors may be conducted in any manner approved by the 
stockholders at the time when the election is held and need not be by ballot.

(c)  All corporate power and authority of the Corporation (except as at the 
time otherwise provided by law, by this Third Restated Certificate of
Incorporation or by the By-Laws) shall be vested in and exercised by the Board
of Directors.

(d)  The Board of Directors shall have the power without the assent or vote of 
the stockholders to adopt, amend, alter or repeal the By-Laws unless the 
By-Laws or this Third Restated Certification of Incorporation otherwise
provide.

SEVENTH:  The Corporation reserves the right to amend or repeal any provision
contained in this Certificate of Incorporation in the manner now or hereafter
prescribed by the laws of the State of Delaware, and all rights herein

   21
conferred upon stockholders or directors are granted subject to this
reservation. 

          EIGHTH:  To the fullest extent permitted by the Delaware General
Corporation Law, no director of the Corporation shall have personal liability to
the Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, provided that nothing in this article shall eliminate or
limit the liability of a director (i) for any breach of the director's duty of
loyalty to the Corporation or its stockholders, (ii) for acts or omissions not
in good faith or which involve intentional misconduct or a knowing violation of
law, (iii) under Section 174 of the Delaware General Corporation Law, or (iv)
for any transaction from which the director derived an improper personal
benefit.  In the event the Delaware General Corporation Law is amended after the
date hereof so as to authorize corporate action further eliminating or limiting
the liability of directors of the Corporation, the liability of the directors
shall thereupon be eliminated or limited to the maximum extent permitted by the
Delaware General Corporation Law, as so amended from time to time.

          NINTH:  The Corporation shall indemnify any person:

          (a)  who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative (other than an action by or in the
right of the Corporation) by reason of the fact that such person is or was a
director, officer, employee or agent of the Corporation, or is or was serving at
the request of the Corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorney's fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by such person in connection with
such action, suit or proceeding if such person acted in good faith and in a
manner he or she reasonably believed to be in or not opposed to the best
interests of the Corporation, and with respect to any criminal action or
proceeding, had no reasonable cause to believe his or her conduct was unlawful.
The termination of any action, suit or proceeding by judgment, order,
settlement, conviction, or upon a plea of nolo contendere or its equivalent,
shall not, of itself, create a presumption that the person did not act in good
faith and in a manner which such person reasonably believed to be in or not
opposed to the best interests of the Corporation or, with respect to any
criminal action or proceeding, that the person had reasonable cause to believe
such person's action was unlawful, or
   22





          (b) who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the right of the
Corporation to procure a judgment in its favor by reason of the fact that such
person is or was a director, officer, employee or agent of the Corporation, or
is or was serving at the request of the Corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust, or
other enterprise against expenses (including attorneys' fees) actually and
reasonably incurred by such person in connection with the defense or settlement
of such action or suit if such person acted in good faith and in a manner he or
she reasonably believed to be in or not opposed to the best interests of the
Corporation, except that no indemnification shall be made in respect of any
claim, issue or matters as to which such person shall have been adjudged to be
liable to the Corporation unless and only to the extent that the Court of
Chancery or the court in which such action or suit was brought shall determine
upon application that, despite the adjudication of liability but in view of all
the circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such expenses which the Court of Chancery or such other court
shall deem proper.

          To the extent that a director, officer, employee or agent of the
Corporation has been successful on the merits or otherwise in defense of any
action, suit or proceeding referred to in paragraph (a) and (b), or in defense
of any claim, issue or matter therein, such person shall be indemnified against
expenses (including attorneys' fees) actually and reasonably incurred by such
person in connection therewith.  The rights conferred on any director of the
Corporation under this Article Ninth shall inure to the benefit of any entity
that is affiliated with such director and that is a stockholder of the
Corporation.

          Any indemnification under paragraph (a) and (b) (unless ordered by a
court) shall be made by the Corporation only as authorized in the specified
case upon a determination that indemnification of the director, officer,
employee or agent is proper in the circumstances because such person has met
the applicable standard of conduct set forth in paragraph (a) and (b).  Such
determination shall be made (1) by the board of directors of a majority vote
of the quorum consisting of directors who were not parties to such action, suit
or proceeding, or (2) if such quorum is not obtainable, or, even if obtainable
a quorum of disinterested directors so directs, by independent legal counsel in
a written opinion, or (3) by the stockholders.

          Expenses incurred by an officer or director in defending a civil or
criminal action, suit or proceeding may be paid by the Corporation in advance of
the final
   23

disposition of such action, suit or proceeding upon receipt of an undertaking
by or on behalf of such director or officer to repay such amount if it shall
ultimately be determined that such person is not entitled to be indemnified by
the Corporation as authorized in this Article Ninth.  Such expenses incurred by
other employees and agents may be so paid upon such terms and conditions, if
any, as the board of directors deems appropriate.

          The indemnification and advancement of expenses provided by or granted
pursuant to this Article Ninth shall not be deemed exclusive of any other rights
to which one seeking indemnification or advancement of expenses may be entitled
under any by-law, agreement, vote of stockholders or disinterested directors or
otherwise, both as to action in his or her official capacity and as to action in
another capacity while holding such office.

          The Corporation may purchase and maintain, insurance on behalf of any
person who is or was a director, officer, employee or agent of the Corporation,
or is or was serving at the request of the Corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise against any liability asserted against him or her and incurred
by him or her in such capacity or arising our of his or her status as such,
whether or not the Corporation would have the power to indemnify such person
against such liability under the provisions of this Article Ninth.

          For purposes of this Article Ninth, references to "the Corporation"
shall include, in addition to the resulting corporation, any constituent
corporation (including any constituent of a constituent) absorbed in a
consolidation or merger which, if its separate existence had continued, would
have the power and authority to indemnify its directors, officers, and employees
or agents, so that any person who is or was a director, officer, employee or
agent of such constituent corporation, or is or was serving at the request of
such constituent corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
shall stand in the same position under this Article Ninth with respect to the
resulting or surviving corporation as he or she would have with respect to such
constituent corporation if its separate existence had continued.

          For purpose of the Article Ninth, references to "other enterprises"
shall include employee benefit plans; references to "fines" shall include any
excise taxes assessed on a person with respect to an employee benefit plan; and
references to "serving at the request of the Corporation" shall include any
service as a director,
   24


officer, employee or agent of the Corporation that imposes duties on, or
involves services by, such director, officer, employee or agent with respect to
an employee benefit plan, its participants, or beneficiaries; and a person who
acted in good faith and in a manner such person reasonably believed to be in
the interest of the participants and beneficiaries of an employee benefit plan
shall be deemed to have acted in a manner "not opposed to the best interests of
the Corporation" as referred to in this Article Ninth.

          The indemnification and advancement of expenses provided by, or
granted pursuant to, this Article Ninth shall continue as to a person who has
ceased to be a director, officer, employee or agent and shall inure to the
benefit of the heirs, executors and administrators of such a person.

          IN WITNESS WHEREOF, the undersigned do execute this Certificate and
affirm and acknowledge, under penalties of perjury, that this Certificate are
their act and deed and that the facts stated herein are true, this 20th day of
December, 1995.

stockholders of the Corporation shall be held on such date, at such time and at
such place within or without the State of Delaware as may be designated by the
Board of Directors, for the purpose of electing Directors and for the
transaction of such other business as may be properly brought before the
meeting.

                 SECTION 2.  Special Meetings.  Except as otherwise provided in
the Certificate of Incorporation, a special meeting of the stockholders of the
Corporation may be called at any time by the Board of Directors or the
President and shall be called by the President or the Secretary at the request
in writing of stockholders holding together at least twenty-five percent of the
number of shares of stock outstanding and entitled to vote at such meeting.
Any special meeting of the stockholders shall be held on such date, at such
time and at such place within or without the State of Delaware as the Board of
Directors or the officer calling the meeting may designate.  At a special
meeting of the stockholders, no business shall be transacted and no corporate
action shall be taken other than that stated in the notice of the meeting
unless all of the stockholders are present in person or by proxy, in which case
any and all business may be transacted at the meeting even though the meeting
is held without notice.

                 SECTION 3.  Notice of Meetings.  Except as otherwise provided
in these
   2
By-Laws or by law, a written notice of each meeting of the stockholders shall
be given not less than ten (10) nor more than sixty (60) days before the date
of the meeting to each stockholder of the Corporation entitled to vote at such
meeting at his address as it appears on the records of the Corporation.  The
notice shall state the place, date and hour of the meeting and, in the case of
a special meeting, the purpose or purposes for which the meeting is called.

holders of a majority in number of the total outstanding shares of stock of the
Corporation entitled to vote at such meeting, present in person or represented
by proxy, shall constitute a quorum of the stockholders for all purposes,
unless the representation of a larger number of shares shall be required by
law, by the Certificate of Incorporation or by these By-Laws, in which case the
representation of the number of shares so required shall constitute a quorum;
provided that at any meeting of the stockholders at which the holders of any
class of stock of the Corporation shall be entitled to vote separately as a
class, the holders of a majority in number of the total outstanding shares of
such class, present in person or represented by proxy, shall constitute a
quorum for purposes of such class vote unless the representation of a larger
number of shares of such class shall be required by law, by the Certificate of
Incorporation or by these By-Laws.

                 SECTION 5.  Adjourned Meetings.  Whether or not a quorum shall
be present in person or represented at any meeting of the stockholders, the
holders of a majority in number of the shares of stock of the Corporation
present in person or represented by proxy and entitled to vote at such meeting
may adjourn from time to time; provided, however, that if the holders of any
class of stock of the Corporation are entitled to vote separately as a class





                                      -2-

action by such class upon such matter shall be determined by the holders of a
majority of the shares of such class present in person or represented by proxy
and entitled to vote at such meeting.  When a meeting is adjourned to another
time or place, notice need not be given of the adjourned meeting if the time
and place thereof are announced at the meeting at which the adjournment is
taken.  At the adjourned meeting the stockholders, or the holders of any class
of stock entitled to vote separately as a class, as the case may be, may
transact any business which might have been transacted by them at the original
meeting.  If the adjournment is for more than thirty days, or if after the
adjournment a new record date is fixed for the adjourned meeting, a notice of
the adjourned meeting shall be given to each stockholder of record entitled to
vote at the adjourned meeting.

                 SECTION 6.  Organization.  The President or, in his absence, a
Vice President shall call all meetings of the stockholders to order, and shall
act as Chairman of such meetings.  In the absence of the President and all of
the Vice Presidents, the holders of a majority in number of the shares of stock
of the Corporation present in person or represented by proxy and entitled to
vote at such meeting shall elect a Chairman.

                 The Secretary of the Corporation shall act as Secretary of all
meetings of the stockholders; but in the absence of the Secretary, the Chairman
may appoint any person to act as Secretary of the meeting.  It shall be the
duty of the Secretary to prepare and make, at least ten days before every
meeting of stockholders, a complete list of stockholders entitled to vote at
such meeting, arranged in alphabetical order and showing the address of each
stockholder and the number of shares registered in the name of each
stockholder.  Such list shall be open,

shall be specified in the notice of the meeting or, if not so specified, at the
place where the meeting is to be held, for the ten days next preceding the
meeting, to the examination of any stockholder, for any purpose germane to the
meeting, during ordinary business hours, and shall be produced and kept at the
time and place of the meeting during the whole time thereof and subject to the
inspection of any stockholder who may be present.

Certificate of Incorporation or by law, each stockholder shall be entitled to
one vote for each share of the capital stock of the Corporation registered in
the name of such stockholder upon the books of the Corporation.  Each
stockholder entitled to vote at a meeting of stockholders or to express consent
or dissent to corporate action in writing without a meeting may authorize
another person or persons to act for him by proxy, but no such proxy shall be
voted or acted upon after three years from its date, unless the proxy provides
for a longer period.  When directed by the presiding officer or upon the demand
of any stockholder, the vote upon any matter before a meeting of stockholders
shall be by ballot.  Except as otherwise provided by law or by the Certificate
of Incorporation, Directors shall be elected by a plurality of the votes cast
at a meeting of stockholders by the stockholders entitled to vote in the
election and, whenever any corporate action other than the election of
Directors is to be taken, it shall be authorized by a majority of the votes
cast at a meeting of stockholders by the stockholders entitled to vote thereon.

                 Shares of the capital stock of the Corporation belonging to
the Corporation or to another corporation, if a majority of the shares entitled
to vote in the election of directors of





                                      -4-
   5
such other corporation is held, directly or indirectly, by the Corporation,
shall neither be entitled to vote nor be counted for quorum purposes.

                 SECTION 8.  Inspectors.  When required by law or directed by
the presiding officer, but not otherwise, the polls shall be opened and closed,
the proxies and ballots shall be received and taken in charge, and all
questions touching the qualification of voters, the validity of proxies and the
acceptance or rejection of votes shall be decided at any meeting of the
stockholders by one or more Inspectors who may be appointed by the Board of
Directors before the meeting, or if not so appointed, shall be appointed by the
presiding officer at the meeting.  If any person so appointed fails to appear
or act, the vacancy may be filled by appointment in like manner.

                 SECTION 9.  Consent of Stockholders in Lieu of Meeting.  To
the fullest extent permitted by law, any action required to be taken or which
may be taken at any annual or special meeting of the stockholders of the
Corporation, may be taken without a meeting, without prior notice and without a
vote, if a consent in writing, setting forth the action so taken, shall be
signed by the holders of outstanding stock having not less than the minimum
number of votes that would be necessary to authorize or take such action at a
meeting at which all shares entitled to vote thereon were present and voted.
Prompt notice of the taking of any such corporate action without a meeting by
less than unanimous written consent shall be given to those stockholders who
have not so consented in writing.

affairs of the Corporation shall be managed by or under the direction of a
Board of not less than five nor more than seven Directors, who need not be
stockholders of the Corporation.  The Directors shall, except as hereinafter
otherwise provided for filling vacancies, be elected at the annual meeting of
stockholders, and shall hold office until their respective successors are
elected and qualified or until their earlier resignation or removal.  The
initial number of Directors constituting the Board shall be five.  The number
of Directors may be altered from time to time by amendment of these By-Laws or
by resolution of the Board of Directors, subject to the provisions of the
Corporation's Certificate of Incorporation.

                 SECTION 2.  Removal, Vacancies and Additional Directors.  The
stockholders may, at any special meeting the notice of which shall state that
it is called for that purpose, remove, with or without cause, any Director and
fill the vacancy; provided that whenever any Director shall have been elected
by the holders of any class of stock of the Corporation voting separately as a
class under the provisions of the Certificate of Incorporation, such Director
may be removed and the vacancy filled only by the holders of that class of
stock voting separately as a class.  Vacancies caused by any such removal and
not filled by the stockholders at the meeting at which such removal shall have
been made, or any vacancy caused by the death or resignation of any Director or
for any other reason, and any newly created directorship resulting from any
increase in the authorized number of Directors, may be filled by the
affirmative vote of a majority of the Directors then in office, although less
than a





                                      -6-
   7
quorum, and any Director so elected to fill any such vacancy or newly created
directorship shall hold office until his successor is elected and qualified or
until his earlier resignation or removal.

                 When one or more Directors shall resign effective at a future
date, a majority of the Directors then in office, including those who have so
resigned, shall have power to fill such vacancy or vacancies, the vote thereon
to take effect when such resignation or resignations shall become effective,
and each Director so chosen shall hold office as herein provided in connection
with the filling of other vacancies.

                 SECTION 3.  Place of Meeting.  The Board of Directors may hold
its meetings in such place or places in the State of Delaware or outside the
State of Delaware as the Board from time to time shall determine.

                 SECTION 4.  Regular Meetings.  Regular meetings of the Board
of Directors shall be held monthly at the offices of the Corporation, or at
such other place as the Board may determine.  No notice shall be required for
any regular meeting of the Board of Directors; but a copy of every resolution
fixing or changing the time or place of regular meetings shall be mailed to
every Director at least five days before the first meeting held in pursuance
thereof.

                 SECTION 5.  Special Meetings.  Special meetings of the Board
of Directors shall be held whenever called by direction of the President, or by
any two of the Directors then in office.

                 Notice of the day, hour and place of holding of each special
meeting shall be given by mailing the same at least two days before the meeting
or by causing the same to be transmitted by telegraph, cable or wireless at
least one day before the meeting to each





                                      -7-
   8
Director.  Unless otherwise indicated in the notice thereof, any and all
business other than an amendment of these By-Laws may be transacted at any
special meeting, and an amendment of these By-Laws may be acted upon if the
notice of the meeting shall have stated that the amendment of these By-Laws is
one of the purposes of the meeting.  At any meeting at which every Director
shall be present, even though without any notice, any business may be
transacted, including the amendment of these By-Laws.

                 SECTION 6.  Quorum.  Subject to the provisions of Section 2 of
this Article II, a majority of the members of the Board of Directors in office
(but in no case less than one-third of the total number of Directors) shall
constitute a quorum for the transaction of business and the vote of the
majority of the Directors present at any meeting of the Board of Directors at
which a quorum is present shall be the act of the Board of Directors.  If at
any meeting of the Board there is less than a quorum present, a majority of
those present may adjourn the meeting from time to time.

                 SECTION 7.  Organization.  A Chairman shall be elected from
the Directors present to preside at all meetings of the Board of Directors.
The Secretary of the Corporation shall act as Secretary of all meetings of the
Directors; but in the absence of the Secretary, the Chairman may appoint any
person to act as Secretary of the meeting.

                 SECTION 8.  Committees.  The Board of Directors may, by
resolution passed by a majority of the whole Board, designate one or more
committees, each committee to consist of one or more of the Directors of the
Corporation.  The Board may designate one or more Directors as alternate
members of any committee, who may replace any absent or disqualified member at
any meeting of the committee.  In the absence or disqualification of a





                                      -8-
   9
member of a committee, the member or members thereof present at any meeting and
not disqualified from voting, whether or not he or they constitute a quorum,
may unanimously appoint another member of the Board of Directors to act at the
meeting in the place of any such absent or disqualified member.  Any such
committee, to the extent provided by resolution passed by a majority of the
whole Board, shall have and may exercise all the powers and authority of the
Board of Directors in the management of the business and the affairs of the
Corporation, and may authorize the seal of the Corporation to be affixed to all
papers which may require it; but no such committee shall have the power or
authority in reference to amending the Certificate of Incorporation, adopting
an agreement of merger or consolidation, recommending to the stockholders the
sale, lease or exchange of all or substantially all of the Corporation's
property and assets, recommending to the stockholders a dissolution of the
Corporation or a revocation of a dissolution, or amending these By-Laws; and
unless such resolution, these By-Laws, or the Certificate of Incorporation
expressly so provide, no such committee shall have the power or authority to
declare a dividend or to authorize the issuance of stock.

                 SECTION 9.  Conference Telephone Meetings.  Unless otherwise
restricted by the Certificate of Incorporation or by these By-Laws, the members
of the Board of Directors or any committee designated by the Board, may
participate in a meeting of the Board or such committee, as the case may be, by
means of conference telephone or similar communications equipment by means of
which all persons participating in the meeting can hear each other, and such
participation shall constitute presence in person at such meeting.

                 SECTION 10.  Consent of Directors or Committee in Lieu of
Meeting.  Unless





                                      -9-
   10
otherwise restricted by the Certificate of Incorporation or by these By-Laws,
any action required or permitted to be taken at any meeting of the Board of
Directors, or of any committee thereof, may be taken without a meeting if all
members of the Board or committee, as the case may be, consent thereto in
writing and the writing or writings are filed with the minutes of proceedings
of the Board or committee, as the case may be.

                 SECTION 11.  Compensation.  The amount, if any, that each
Director shall be entitled to receive as compensation for his services as such
shall be fixed from time to time by resolution of the Board of Directors;
provided that only independent directors may receive compensation for services
as a director of the Corporation.  Directors shall not be entitled to receive
reimbursement from the Corporation for expenses in connection with their
attendance at any meeting of the Board of Directors.

                                  ARTICLE III

                                    OFFICERS

                 SECTION 1.  Officers.  The officers of the Corporation shall
be a President, one or more Vice Presidents, a Secretary and a Treasurer, and
such additional officers, if any, as shall be elected by the Board of Directors
pursuant to the provisions of Section 6 of this Article III.  The President,
one or more Vice Presidents, the Secretary and the Treasurer shall be elected
by the Board of Directors at its first meeting after each annual meeting of the
stockholders.  The failure to hold such election shall not of itself terminate
the term of office of any officer.  All officers shall hold office at the
pleasure of the Board of Directors.  Any officer may resign at any time upon
written notice to the Corporation.  Officers may, but need not, be Directors.
Any number of offices may be held by the same person.





                                      -10-
   11
                 All officers, agents and employees shall be subject to
removal, with or without cause, at any time by the Board of Directors.  The
removal of an officer without cause shall be without prejudice to his contract
rights, if any.  The election or appointment of an officer shall not of itself
create contract rights.  All agents and employees other than officers elected
by the Board of Directors shall also be subject to removal, with or without
cause, at any time by the officers appointing them.

                 Any vacancy caused by the death of any officer, his
resignation, his removal, or otherwise, may be filled by the Board of
Directors, and any officer so elected shall hold office at the pleasure of the
Board of Directors.

                 In addition to the powers and duties of the officers of the
Corporation as set forth in these By-Laws, the officers shall have such
authority and shall perform such duties as from time to time may be determined
by the Board of Directors.

                 SECTION 2.  Powers and Duties of the President.  Unless
otherwise determined by the Board of Directors, the President shall be the
chief executive officer of the Corporation and, subject to the control of the
Board of Directors, shall have general charge and control of all its business
and affairs and shall perform all duties incident to the office of President.

Board of Directors and shall have such other powers and perform such other
duties as may from time to time be assigned to him by these By-Laws or by the
Board of Directors.

                 SECTION 3.  Powers and Duties of the Vice Presidents.  Each
Vice President shall perform all duties incident to the office of Vice
President and shall have such other powers and perform such other duties as may
from time to time be assigned to him by these





                                      -11-
   12
By-Laws or by the Board of Directors or the President.

                 SECTION 4.  Powers and Duties of the Secretary.  The Secretary

same to such documents and other papers as the Board of Directors or the
President shall authorize and direct; he shall have charge of the stock
certificate books, transfer books and stock ledgers and such other books and
papers as the Board of Directors or the President shall direct, all of which
shall at all reasonable times be open to the examination of any Director, upon
application, at the office of the Corporation during business hours; and he
shall perform all duties incident to the office of Secretary and shall also
have such other powers and shall perform such other duties as may from time to
time be assigned to him by these By-Laws or the Board of Directors or the
President.

                 SECTION 5.  Powers and Duties of the Treasurer.  The Treasurer
shall have custody of, and when proper shall pay out, disburse or otherwise
dispose of, all funds and securities of the Corporation which may have come
into his hands; he may endorse on behalf of the Corporation for collection
checks, notes and other obligations and shall deposit the same to the credit of
the Corporation in such bank or banks or depositary or depositaries as the
Board of Directors may designate; he shall sign all receipts and vouchers for
payments made to the Corporation; he shall enter or cause to be entered
regularly in the books of the Corporation kept for the purpose full and
accurate accounts of all moneys received or paid or otherwise disposed of by
him and whenever required by the Board of Directors or the





                                      -12-
   13
President shall render statements of such accounts; he shall, at all reasonable
times, exhibit his books and accounts to any Director of the Corporation upon
application at the office of the Corporation during business hours; and he
shall perform all duties incident to the office of Treasurer and shall also
have such other powers and shall perform such other duties as may from time to
time be assigned to him by these By-Laws or by the Board of Directors or the
President.

                 SECTION 6.  Additional Officers.  The Board of Directors may
from time to time elect such other officers (who may but need not be
Directors), including a Controller, Chief Financial Officer, a Chief Technical
Officer and one or more Assistant Treasurers, Assistant Secretaries and
Assistant Controllers, as the Board may deem advisable, and such officers shall
have such authority and shall perform such duties as may from time to time be
assigned to them by the Board of Directors or the President.

                 The Board of Directors may from time to time by resolution
delegate to any Assistant Treasurer or Assistant Treasurers any of the powers
or duties herein assigned to the Treasurer; and may similarly delegate to any
Assistant Secretary or Assistant Secretaries any of the powers or duties herein
assigned to the Secretary.

                 SECTION 7.  Giving of Bond by Officers.  All officers of the
Corporation, if required to do so by the Board of Directors, shall furnish
bonds to the Corporation for the faithful performance of their duties, in such
penalties and with such conditions and security as the Board shall require.

                 SECTION 8.  Voting Upon Stocks.  Unless otherwise ordered by
the Board of Directors, the President or any Vice President shall have full
power and authority on behalf of





                                      -13-
   14
the Corporation to attend and to act and to vote, or in the name of the
Corporation to execute proxies to vote, at any meetings of stockholders of any
corporation in which the Corporation may hold stock, and at any such meetings
shall possess and may exercise, in person or by proxy, any and all rights,
powers and privileges incident to the ownership of such stock.  The Board of
Directors may from time to time, by resolution, confer like powers upon any
other person or persons.

                 SECTION 9.  Compensation of Officers.  The officers of the
Corporation shall be entitled to receive such compensation for their services
as shall from time to time be determined by the Board of Directors (or the
Compensation Committee of the Board, if one exists).

                                   ARTICLE IV

                             STOCK-SEAL-FISCAL YEAR

                 SECTION 1.  Certificates For Shares of Stock.  The
certificates for shares of stock of the Corporation shall be in such form, not
inconsistent with the Certificate of Incorporation, as shall be approved by the
Board of Directors.  All certificates shall be signed by the President or a
Vice President and by the Secretary or an Assistant Secretary or the Treasurer
or an Assistant Treasurer, and shall not be valid unless so signed.

                 In case any officer or officers who shall have signed any such
certificate or certificates shall cease to be such officer or officers of the
Corporation, whether because of death, resignation or otherwise, before such
certificate or certificates shall have been delivered by the Corporation, such
certificate or certificates may nevertheless be issued and delivered as though
the person or persons who signed such certificate or certificates had not
ceased to be





                                      -14-
   15
such officer or officers of the Corporation.

                 All certificates for shares of stock shall be consecutively
numbered as the same are issued.  The name of the person owning the shares
represented thereby with the number of such shares and the date of issue
thereof shall be entered on the books of the Corporation.

                 Except as hereinafter provided, all certificates surrendered
to the Corporation for transfer shall be cancelled, and no new certificates
shall be issued until former certificates for the same number of shares have
been surrendered and cancelled.

                 SECTION 2.  Lost, Stolen or Destroyed Certificates.  Whenever
a person owning a certificate for shares of stock of the Corporation alleges
that it has been lost, stolen or destroyed, he shall file in the office of the
Corporation an affidavit setting forth, to the best of his knowledge and
belief, the time, place and circumstances of the loss, theft or destruction,
and, if required by the Board of Directors, a bond of indemnity or other
indemnification sufficient in the opinion of the Board of Directors to
indemnify the Corporation and its agents against any claim that may be made
against it or them on account of the alleged loss, theft or destruction of any
such certificate or the issuance of a new certificate in replacement therefor.
Thereupon the Corporation may cause to be issued to such person a new
certificate in replacement for the certificate alleged to have been lost,
stolen or destroyed.  Upon the stub of every new certificate so issued shall be
noted  the fact of such issue and the number, date and the name of the
registered owner of the lost, stolen or destroyed certificate in lieu of which
the new certificate is issued.

                 SECTION 3.  Transfer of Shares.  Shares of stock of the
Corporation shall be transferred on the books of the Corporation by the holder
thereof, in person or by his attorney





                                      -15-
   16
duly authorized in writing, upon surrender and cancellation of certificates for
the number of shares of stock to be transferred, except as provided in the
preceding section.

                 SECTION 4.  Regulations.  The Board of Directors shall have
power and authority to make such rules and regulations as it may deem expedient
concerning the issue, transfer and registration of certificates for shares of
stock of the Corporation.

                 SECTION 5.  Record Date.  In order that the Corporation may
determine the stockholders entitled to notice of or to vote at any meeting of
stockholders or any adjournment thereof, or to express consent to corporate
action in writing without a meeting or entitled to receive payment of any
dividend or other distribution or allotment of any rights, or entitled to
exercise any rights in respect of any change, conversion or exchange of stock
or for the purpose of any other lawful action, as the case may be, the Board of
Directors may fix, in advance, a record date, which shall not be more than
sixty (60) nor less than ten (10) days before the date of such meeting, nor
more than sixty (60) days prior to any other action.

                 If no record date is fixed, the record date for determining
stockholders entitled to notice of or to vote at a meeting of stockholders
shall be at the close of business on the day next preceding the day on which
notice is given, or, if notice is waived, at the close of business on the day
next preceding the day on which the meeting is held; the record date for
determining stockholders entitled to express consent to corporate action in
writing without a meeting, when no prior action by the Board of Directors is
necessary, shall be the day on which the first written consent is expressed;
and the record date for determining stockholders for any other purpose shall be
at the close of business on the day on which the Board of Directors adopts the
resolution relating thereto.  A determination of stockholders of record





                                      -16-
   17
entitled to notice of or to vote at a meeting of stockholders shall apply to
any adjournment of the meeting; provided, however, that the Board of Directors
may fix a new record date for the adjourned meeting.

                 SECTION 6.  Dividends.  Subject to the provisions of the
Certificate of Incorporation, the Board of Directors shall have power to
declare and pay dividends upon shares of stock of the Corporation, but only out
of funds available for the payment of dividends as provided by law.

                 Subject to the provisions of the Certificate of Incorporation,
any dividends declared upon the stock of the Corporation shall be payable on
such date or dates as the Board  of Directors shall determine.  If the date
fixed for the payment of any dividend shall in any year fall upon a legal
holiday, then the dividend payable on such date shall be paid on the next day
not a legal holiday.

                 SECTION 7.  Corporate Seal.  The Board of Directors shall
provide a suitable seal, containing the name of the Corporation, which seal
shall be kept in the custody of the Secretary.  A duplicate of the seal may be
kept and be used by any officer of the Corporation designated by the Board or
the President.

                 SECTION 8.  Fiscal Year.  The fiscal year of the Corporation
shall be such fiscal year as the Board of Directors from time to time by
resolution shall determine.

                 SECTION 1.  Checks, Notes, etc.  All checks, drafts, bills of
exchange, acceptances, notes or other obligations or orders for the payment of
money shall be signed and, if so required by the Board of Directors,
countersigned by such officers of the Corporation and/or other persons as shall
from time to time be designated by the Board of Directors or pursuant to
authority delegated by the Board.

                 Checks, drafts, bills of exchange, acceptances, notes,

duly authorized depositary by the Treasurer and/or such other officers or
persons as shall from time to time be designated by the Treasurer.

                 SECTION 2.  Loans.  No loans and no renewals of any loans
shall be contracted on behalf of the Corporation except as authorized by the
Board of Directors.  When authorized so to do, any officer or agent of the
Corporation may effect loans and advances for the Corporation from any bank,
trust company or other institution or from any firm, corporation or individual,
and for such loans and advances may make, execute and deliver promissory notes,
bonds or other evidences of indebtedness of the Corporation.  When authorized
so to do, any officer or agent of the Corporation may pledge, hypothecate or
transfer, as security for the payment of any and all loans, advances,
indebtedness and liabilities of the Corporation, any and all stocks, securities
and other personal property at any time held by the Corporation, and to that
end may endorse, assign and deliver the same.  Such authority may be general or
confined to specific instances.

   19
                 SECTION 3.  Waivers of Notice.  Whenever any notice whatever
is required to be given by law, by the Certificate of Incorporation or by these
By-Laws to any person or persons, a waiver thereof in writing, signed by the
person or persons entitled to the notice, whether before or after the time
stated therein, shall be deemed equivalent thereto.  The attendance of any
person at a meeting shall constitute a waiver of notice of such meeting, except
when the person attends a meeting for the express purpose of objecting, at the
beginning of the meeting, to the transaction of any business on the ground that
the meeting is not lawfully called or convened.

                 SECTION 4.  Offices Outside of Delaware.  Except as otherwise
required by the laws of the State of Delaware, the Corporation may have an
office or offices and keep its books, documents and papers outside of the State
of Delaware at such place or places as from time to time may be determined by
the Board of Directors or the President.

                 SECTION 5.  Indemnification of Directors, Officers and
Employees.  The Corporation shall, to the fullest extent permitted by
applicable law from time to time in effect, indemnify any and all persons who
may serve or who have served at any time as Directors or officers of the
Corporation, or who at the request of the Corporation may serve or at any time
have served as Directors or officers of another corporation (including
subsidiaries of the Corporation) or of any partnership, joint venture, trust or
other enterprise, from and against any and all of the expenses, liabilities or
other matters referred to in or covered by said law.  Such indemnification
shall continue as to a person who has ceased to be a Director or officer and
shall inure to the benefit of the heirs, executors and administrators of such a
person.  The Corporation may also indemnify any and all other persons whom it
shall have power to





                                      -19-
   20
indemnify under any applicable law from time to time in effect to the extent
authorized by the Board of Directors and permitted by such law.  The
indemnification provided by this Article shall not be deemed exclusive of any
other rights to which any person may be entitled under any provision of the
Certificate of Incorporation, other By-law, agreement, vote of stockholders or
disinterested Directors, or otherwise, both as to action in his official
capacity and as to action in another capacity while holding such office.

                 For purposes of this Section 5, the term "Corporation" shall
include constituent corporations referred to in Subsection (h) of the Section
145 of the General Corporation Law (or any similar provision of applicable law
at the time in effect).

                 SECTION 6.  Voting as Stockholder.  Unless otherwise
determined by resolution of the Board of Directors, the President or any Vice
President shall have full power and authority on behalf of the Corporation to
attend any meeting of stockholders of any corporation in which the Corporation
may hold stock, and to act, vote (or execute proxies to vote) and exercise in
person or by proxy all other rights, powers and privileges incident to the
ownership of such stock.  Such officers acting on behalf of the Corporation
shall have full power and authority to execute any instrument expressing
consent to or dissent from any action of any such corporation without a
meeting.  The Board of Directors may by resolution from time to time confer
such power and authority upon any other person or persons.

                 SECTION 7.  Construction.  In the event of any conflict
between the provisions of these By-laws as in effect from time to time and the
provisions of the Certificate of Incorporation of the Corporation as in effect
from time to time, the provisions of such Certificate of Incorporation shall be

                 These By-Laws and any amendment thereof may be altered,
amended or repealed, or new By-Laws may be adopted, by the Board of Directors
at any regular or special meeting by the affirmative vote of a majority of all
of the members of the Board, provided in the case of any special meeting at

the By-Laws adopted by the Board of Directors, may be altered, amended or
repealed and other By-Laws may be adopted by the holders of a majority of the
total outstanding stock of the Corporation entitled to vote at any annual

                 AGREEMENT, made this th day of     , 19  , between CIENA
 Corporation, a Delaware corporation (the "Company"), and (the "Indemnitee"),
 with respect to the following facts:

                 A.    Fulfilling the potential of the Company requires the
attraction and retention of qualified and capable directors, officers,
employees, agents and fiduciaries; and

                 B.    The Restated Certificate of Incorporation of the Company
(the "Restated Certificate of Incorporation") requires the Company to indemnify
and advance expenses to its directors and officers to the fullest extent
authorized by law and allows the Company to indemnify employees and agents to
the fullest extent authorized by law; and

                 C.    Historically, basic protection against undue risk of
personal liability of directors and officers has been provided through
insurance coverage providing reasonable protection at reasonable cost; and

                 D.    The Company's current stage of development is such that
it is presently uncertain whether, and to what extent, directors' and officers'
liability insurance is or will continue to be available to the Company at a
reasonable cost for the protection of Indemnitee; and

                 E.    It is the policy of the Company to indemnify its
directors and officers so as to provide them with the maximum possible
protection permitted by law; and

                 F.    In recognition of Indemnitee's need for protection
against personal liability in order to induce Indemnitee to serve or continue
to serve the Company in an effective manner, and, in the case of directors and
officers, to supplement or replace directors' and officers' liability insurance
coverage, if any, obtained by the Company, and in part to provide Indemnitee
with specific contractual assurance that the protection promised by the
Restated Certificate of Incorporation will be available to Indemnitee
(regardless of, among other things, any amendment to or revocation of the
Restated Certificate of Incorporation or any change in the composition of the
Company's Board of Directors or any acquisition transaction relating to the
Company), the Company, with the prior approval of the Company's stockholders,
wishes to provide the Indemnitee with the benefits contemplated by this
Agreement; and

                 G.    As a result of the provision of such benefits Indemnitee
has agreed to serve or to continue to serve the Company;

                 NOW, THEREFORE, the parties hereto do hereby agree as follows:

                       1.     Definitions.  The following terms, as used

   5
the event Indemnitee is or becomes a party to or witness or other participant
in, or is threatened to be made a party to or witness or other participant in,
a Claim by reason of (or arising in part out of) an Indemnifiable Event, the
Company will indemnify Indemnitee to the fullest extent authorized by law,

                       3.     Limitations on Indemnification.  Notwithstanding
the provisions of Section 2, Indemnitee shall not be indemnified and held

provided herein, to constitute an Excluded Claim; (b) to the extent Indemnitee
is indemnified by the Company and has actually received payment pursuant to the
Restated Certificate of Incorporation, D&O Insurance, or otherwise; or (c)
other than pursuant to the last sentence of Section 4(d) or Section 14, in
connection with any Claim initiated by Indemnitee, unless the Company has
joined in or the Board of Directors has authorized such Claim.

                       4.     Indemnification Procedures.

                              a.  Promptly after receipt by Indemnitee of
notice of any Claim, Indemnitee shall, if indemnification with respect thereto
may be sought from the Company under this Agreement, notify the Company of the
commencement thereof and Indemnitee agrees further not to make any admission or
effect any settlement with respect to such Claim without the consent of the
Company, except any Claim with respect to which the Indemnitee has undertaken
the defense in accordance with the second to last sentence of Section 4(d).

                              b.  If, at the time of the receipt of such
notice, the Company has D&O Insurance in effect, the Company shall give prompt
notice of the commencement of Claim to the insurers in accordance with the
procedures set forth in the respective policies.  The Company shall thereafter
take all necessary or desirable action to cause such insurers to pay, on behalf
of Indemnitee, all Losses and Expenses payable as a result of such Claim.

                              c.  To the extent the Company does not, at the
time of the Claim have applicable D&O Insurance, or if a Determination is made
that any Expenses arising out of such Claim will not be payable under the D&O
Insurance then in effect, the Company shall be obligated to pay the Expenses of
any Claim in advance of the final disposition thereof and the Company, if
appropriate, shall be entitled to assume the defense of such Claim, with
counsel satisfactory to Indemnitee, upon the delivery to Indemnitee of written
notice of its election so to do.  After delivery of such notice, the Company
will not be liable to Indemnitee under this Agreement for any legal or other
Expenses subsequently incurred by the Indemnitee in connection with such
defense other than reasonable Expenses of investigation; provided that
Indemnitee shall have the right to employ its counsel in such Claim but the
fees and expenses of such counsel incurred after delivery of notice from the
Company of its assumption of such defense shall be at the Indemnitee's expense;
provided further that if:  (i) the employment of counsel by Indemnitee has been
previously authorized by the Company; (ii) Indemnitee shall have reasonably
concluded that there may be a conflict of interest between the Company and
Indemnitee in the conduct of any such defense; or (iii) the Company shall not,
in fact, have employed counsel to assume the defense of such action, the
reasonable fees and expenses of counsel shall be at the expense of the Company.





                                                                               5
   6
                              d.  All payments on account of the Company's
indemnification obligations under this Agreement shall be made within sixty
(60) days of Indemnitee's written request therefor unless a Determination is
made that the Claims giving rise to Indemnitee's request are Excluded Claims or
otherwise not payable under this Agreement, provided that all payments on
account of the Company's obligation to pay Expenses under Section 4(c) of this
Agreement prior to the final disposition of any Claim shall be made within 20
days of Indemnitee's written request therefor and such obligation shall not be
subject to any such Determination but shall be subject to Section 4(e) of this
Agreement.  In the event the Company takes the position that the Indemnitee is
not entitled to indemnification in connection with the proposed settlement of
any Claim, the Indemnitee shall have the right at its own expense to undertake
defense of any such Claim, insofar as such proceeding involves Claims against
the Indemnitee, by written notice given to the Company within 10 days after the
Company has notified the Indemnitee in writing of its contention that the
Indemnitee is not entitled to indemnification.  If it is subsequently
determined in connection with such proceeding that the Indemnifiable Events are
not Excluded Claims and that the Indemnitee, therefore, is entitled to be
indemnified under the provisions of Section 2 hereof, the Company shall
promptly indemnify the Indemnitee.

                              e.  Indemnitee hereby expressly undertakes and
agrees to reimburse the Company for all Losses and Expenses paid by the Company
in connection with any Claim against Indemnitee in the event and only to the
extent that a Determination shall have been made by a court of competent
jurisdiction in a decision from which there is no further right to appeal that
Indemnitee is not entitled to be indemnified by the Company for such Losses and
Expenses because the Claim is an Excluded Claim or because Indemnitee is
otherwise not entitled to payment under this Agreement.

                       5.     Settlement.  The Company shall have no obligation
to indemnify Indemnitee under this Agreement for any amounts paid in settlement
of any Claim effected without the Company's prior written consent.  The Company
shall not settle any Claim in which it takes the position that Indemnitee is
not entitled to indemnification in connection with such settlement without the
consent of the Indemnitee, nor shall the Company settle any Claim in any manner
which would impose any Fine or any obligation on Indemnitee, without
Indemnitee's written consent.  Neither the Company nor Indemnitee shall
unreasonably withhold their consent to any proposed settlement.

                       6.     Change in Control; Extraordinary Transactions.
The Company and Indemnitee agree that if there is a Change in Control of the
Company (other than a Change in Control which has been approved by a majority
of the Company's Board of Directors who were directors immediately prior to
such Change in Control) then all Determinations thereafter with respect to the
rights of Indemnitee to be paid Losses and Expenses under this Agreement shall
be made only by a special independent counsel (the "Special Independent
Counsel") selected by Indemnitee and approved by the Company (which approval
shall not be unreasonably withheld) or by a court of competent jurisdiction.
The Company shall pay the reasonable fees of such Special Independent Counsel
and shall indemnify such Special Independent Counsel against any and all
reasonable expenses (including reasonable attorneys' fees), claims, liabilities
and damages arising out of or relating to this Agreement or its engagement
pursuant hereto.

                 The Company covenants and agrees that, in the event of a
Change in Control of the sort set forth in clause (b) of Section 1(c), the
Company will use its best efforts (a) to have the obligations of the Company
under this Agreement including, but not limited to those under Section 7,
expressly assumed by the surviving, purchasing or succeeding entity, or (b)
otherwise to adequately provide for





                                                                               6
   7
the satisfaction of the Company's obligations under this Agreement, in a manner
reasonably acceptable to the Indemnitee.

                       7.     Establishment of Trust.  In the event of a
Potential Change in Control, the Company shall, upon written request by
Indemnitee, create a trust (the "Trust") for the benefit of the Indemnitee and
from time to time upon written request of Indemnitee shall fund the Trust in an
amount sufficient to satisfy any and all Losses and Expenses which are actually
paid or which Indemnitee reasonably determines from time to time may be payable
by the Company under this Agreement.  The amount or amounts to be deposited in
the Trust pursuant to the foregoing funding obligation shall be determined by
the Reviewing Party, in any case in which the Special Independent Counsel is
involved.  The terms of the Trust shall provide that upon a Change in Control:
(i) the Trust shall not be revoked or the principal thereof invaded without the
written consent of the Indemnitee; (ii) the trustee of the Trust shall advance,
within twenty days of a request by the Indemnitee, any and all Expenses to the
Indemnitee (and the Indemnitee hereby agrees to reimburse the Trust under the
circumstances under which the Indemnitee would be required to reimburse the
Company under Section 4(e) of this Agreement); (iii) the Company shall continue
to fund the Trust from time to time in accordance with the funding obligations
set forth above; (iv) the trustee of the Trust shall promptly pay to the
Indemnitee all Losses and Expenses for which the Indemnitee shall be entitled
to indemnification pursuant to this Agreement; and (v) all unexpended funds in
the Trust shall revert to the Company upon a final determination by a court of
competent jurisdiction in a final decision from which there is no further right
of appeal that the Indemnitee has been fully indemnified under the terms of
this Agreement.  The Trustee of the Trust shall be chosen by the Indemnitee.

                       8.     No Presumption.  For purposes of this Agreement,
the termination of any Claim by judgment, order, settlement (whether with or
without court approval) or conviction, or upon a plea of nolo contendere, or
its equivalent, shall not, of itself, create a presumption that Indemnitee did
not meet any particular standard of conduct or have any particular belief or
that a court has determined that indemnification is not permitted by applicable
law.

                       9.     Non-exclusivity, Etc.  The rights of the
Indemnitee hereunder shall be in addition to any other rights Indemnitee may
have under the Restated Certificate of Incorporation, the Company's By-laws,
the Delaware General Corporation Law, any vote of stockholders or disinterested
directors or otherwise, both as to action in the Indemnitee's official capacity
and as to action in any other capacity by holding such office, and shall
continue after the Indemnitee ceases to serve the Company as a director,
officer, employee, agent or fiduciary, for so long as the Indemnitee shall be
subject to any Claim by reason of (or arising in part out of) an Indemnifiable
Event.  To the extent that a change in the Delaware General Corporation Law
(whether by statute or judicial decision) permits greater indemnification by
agreement than would be afforded currently under the Restated Certificate of
Incorporation and this Agreement, it is the intent of the parties hereto that
Indemnitee shall enjoy by this Agreement the greater benefits so afforded by
such change.

                       10.    Liability Insurance.  To the extent the Company
maintains an insurance policy or policies providing directors' and officers'
liability insurance, Indemnitee, if an officer or director of the Company,
shall be covered by such policy or policies, in accordance with its or their
terms, to the maximum extent of the coverage available for any director or
officer of the Company.

                       11.    Subrogation.  In the event of payment under this
Agreement, the Company shall be subrogated to the extent of such payment to all
of the rights of recovery of Indemnitee, who shall execute all papers required
and shall do everything that may be necessary to secure such rights,





                                                                               7
   8
including the execution of such documents necessary to enable the Company
effectively to bring suit to enforce such rights.

                       12.    Partial Indemnity, Etc.  If Indemnitee is
entitled under any provision of this Agreement to indemnification by the
Company for some or a portion of the Expenses and Losses of a Claim but not,
however, for all of the total amount thereof, the Company shall nevertheless
indemnify Indemnitee for the portion thereof to which Indemnitee is entitled.
Moreover, notwithstanding any other provision of this Agreement, to the extent
that Indemnitee has been successful on the merits or otherwise in defense of
any or all Claims relating in whole or in part to any Indemnifiable Event or in
defense of any issue or matter therein, including dismissal without prejudice,
Indemnitee shall be indemnified against all Expenses incurred in connection
therewith.  In connection with any Determination as to whether Indemnitee is
entitled to be indemnified hereunder the burden of proof shall be on the
Company to establish that Indemnitee is not so entitled.

                       13.    Liability of Company.  The Indemnitee agrees that
neither the stockholders nor the directors nor any officer, employee,
representative or agent of the Company shall be personally liable for the
satisfaction of the Company's obligations under this Agreement and the
Indemnitee shall look solely to the assets of the Company for satisfaction of
any claims hereunder.

                       14.    Enforcement.

rights under this Agreement shall be specifically enforceable by Indemnitee
only in the state or Federal courts of the States of Delaware or Maryland and
shall be enforceable notwithstanding any adverse Determination by the Company's
Board of Directors, independent legal counsel, the Special Independent Counsel
or the Company's stockholders and no such Determination shall create a
presumption that Indemnitee is not entitled to be indemnified hereunder.  In
any such action the Company shall have the burden of proving that
indemnification is not required under this Agreement.

                              In the event that any action is instituted by
Indemnitee under this Agreement, or to enforce or interpret any of the terms of
this Agreement, Indemnitee shall be entitled to be paid all court costs and
reasonable expenses, including reasonable counsel fees, incurred by Indemnitee
with respect to such action, unless the court determines that each of the
material assertions made by Indemnitee as a basis for such action were not made
in good faith or were frivolous.

                       15.    Severability.  In the event that any provision of
this Agreement is determined by a court to require the Company to do or to fail
to do an act which is in violation of applicable law, such provision (including
any provision within a single section, paragraph or sentence) shall be limited
or modified in its application to the minimum extent necessary to avoid a
violation of law, and, as so limited or modified, such provision and the
balance of this Agreement shall be enforceable in accordance with their terms
to the fullest extent permitted by law.

                       16.    Governing Law.  This Agreement shall be governed
by and construed in accordance with the laws of the State of Delaware
applicable to agreements made and to be performed entirely within such State.

Indemnitee each hereby irrevocably consent to the jurisdiction of the courts of
the States of Delaware and Maryland for all purposes in connection with any
action or proceeding which arises out of or relates to this Agreement





                                                                               8

covered thereby, in such form as the Board shall from time to time establish, 
which agreements may incorporate all or any of the terms of the Plan by 
reference and shall comply with and be subject to the following terms and
conditions:

                 (a) Exercise Price. The exercise price for each Option shall
be established in the sole discretion of the Board; provided, however, that (i)
the exercise price per share for an Incentive Stock Option shall be not less
than the fair market value, as determined by the Board, of a share of
   3
Stock on the date of the granting of the Option; (ii) the exercise price per
share for a non-statutory stock option shall not be less than eighty-five
percent (85%) of the fair market value, as determined by the Board, of a share
of Stock on the date of the granting of the Option; and (iii) no Incentive
Stock Option granted to an Optionee who at the time the Option is granted owns
stock possessing more than ten percent (10%) of the total combined voting power
of all classes of stock of a Participating Company within the meaning of
Section 422(b)(6) of the Code (a "Ten Percent Owner Optionee") shall have an
exercise price per share less than one hundred ten percent (110%) of the fair
market value, as determined by the Board, of a share of Stock on the date of
the granting of the Option. Notwithstanding the foregoing, an Option (whether
an Incentive Stock Option or a non-statutory stock option) may be granted with
an exercise price lower than the minimum exercise price set forth above if such
Option is granted pursuant to an assumption or substitution for another option
in a manner qualifying with the provisions of Section 424(a) of the Code.

          (b)      Exercise Period of Options. The Board shall have the power 
to set,  including by amendment of an Option, the time or times within which
each  Option shall be exercisable or the event or events upon the occurrence of 
which all or a portion of each Option shall be exercisable and the term of 
each Option; provided, however, that (i) no Option shall be exercisable after 
the expiration of ten (10) years after the date such Option is granted, and 
(ii) no Incentive Stock Option granted to a Ten Percent Owner Optionee shall 
be exercisable after the expiration of five (5) years after the date such 
Option is granted.

          (c) Payment of Exercise Price.

                   (i)      Forms of Payment Authorized. Payment of the 
exercise price for the number of shares of Stock being purchased pursuant to
any Option shall be made (1) in cash, by check, or cash equivalent, (2) by
tender to the Company of shares of the Company's stock owned by the Optionee
having a fair market value, as determined by the Board (but without regard to
any restrictions on transferability applicable to such stock by reason of
federal or state securities laws or agreements with an underwriter for the
Company), not less than the exercise price, (3) by the Optionee's recourse
promissory note in a form approved by the Company, (4) by the assignment of
the proceeds of a sale of some or all of the shares being acquired upon the
exercise of the Option (including, without limitation, through an exercise
complying with the provisions of Regulation T as promulgated from time to time
by the Board of Governors of the Federal Reserve System), or (5) by any
combination thereof. The Board may at any time or from time to time grant
Options which do not permit all of the foregoing forms of consideration to be
used in payment of the exercise price and/or which otherwise restrict one or
more forms of consideration.

                   (ii)     Tender of Company Stock. Notwithstanding the
foregoing, an Option may not be exercised by tender to the Company of shares of
the Company's stock to the extent such tender of stock would constitute a
violation of the provisions of any law, regulation and/or agreement restricting
the redemption of the Company's stock or, if in the opinion of Company counsel,
might impair the ability of purchasers of stock from the Company from taking
full advantage of the provisions of Section 1202 of the Code relating to
capital gains treatment of stock issued by the Company. Unless otherwise
provided by the Board, an Option may not be exercised by tender to the Company
of shares of the Company's stock unless such shares of the Company's stock
either have been owned by the Optionee for more than six (6) months or were not
acquired, directly or indirectly, from the Company.
   4
                   (iii)      Promissorv Notes. No promissory note shall
be permitted if an exercise using a promissory note would be a violation of any
law. Any permitted promissory note shall be due and payable not more than four
(4) years after the Option is exercised, and interest shall be payable at least
annually and be at least equal to the minimum interest rate necessary to avoid
imputed interest pursuant to all applicable sections of the Code. The Board
shall have the authority to permit or require the Optionee to secure any
promissory note used to exercise an Option with the shares of Stock acquired on
exercise of the Option and/or with other collateral acceptable to the Company.
Unless otherwise provided by the Board, in the event the Company at any time is
subject to the regulations promulgated by the Board of Governors of the Federal
Reserve System or any other governmental entity affecting the extension of
credit in connection with the Company's securities, any promissory note shall
comply with such applicable regulations, and the Optionee shall pay the unpaid
principal and accrued interest, if any, to the extent necessary to comply with
such applicable regulations.

                   (iv)       Assignment of Proceeds of Sale. The Company 
reserves, at any and all times, the right, in the Company's sole and absolute
discretion, to establish. decline to approve and/or terminate any program
and/or procedures for the exercise of Options by means of an assignment of the
proceeds of a sale of some or all of the shares of Stock to be acquired upon
such exercise.


        7. Standard Forms of Stock Option Agreement.

                 (a)      Incentive Stock Options. Unless otherwise provided
for by the Board at the time an Option is granted, an Option designated as an
"Incentive Stock Option" shall comply with and be subject to the terms and
conditions set forth in the form of incentive stock option agreement attached
hereto as Exhibit A and incorporated herein by reference.

                 (b)      Non-statutory Stock Options. Unless otherwise
provided for by the Board at the time an Option is granted, an Option
designated as a "Non-statutory Stock Option" shall comply with and be subject
to the terms and conditions set forth in the forms of non-statutory stock
option agreement attached hereto as Exhibit B and incorporated herein by
reference.

                 (c)      Standard Term for Options. Unless otherwise provided
for by the Board in the grant of an Option, any Option granted hereunder shall
be exercisable for a term of [ten (10)] years.

            8. Authority to Vary Terms. 

The Board shall have the authority from time to time to vary the terms of 
either of the standard forms of Stock Option Agreement described in paragraph 
7 above either in connection with the grant or amendment of an individual 
Option or in connection with the authorization of a new standard form or 
forrns: provided, however, that the terms and conditions of such revised or 
amended standard form or forms of stock option agreement shall be in 
accordance with the terms of the Plan. Such authority shall include, but not 
by way of limitation, the authority to grant Options which are not immediately 
exercisable.

            9. Fair Market Value Limitation. 

To the extent that the aggregate fair market value (determined at the time the 
Option is granted) of stock with respect to which Incentive Stock Options are 
exercisable by an Optionee for the first time during any calendar year (under 
all stock option plans of the Company, including the Plan) exceeds One Hundred 
Thousand Dollars ($100,000), such Options shall be treated as non-statutory 
stock options. This paragraph shall be applied by taking Incentive Stock 
Options into account in the order in which they were granted.
   5
            10. Effect of Change in Stock Subject to Plan. 

Appropriate adjustments shall be made in the number and class of shares of 
Stock subject to the Plan and to any outstanding Options and in the exercise 
price of any outstanding Options in the event of a stock dividend, stock split,
reverse stock split, recapitalization, combination, reclassificationt or like 
change in the capital structure of the Company.

In the event a majority of the shares which are of the same class as the shares
that are subject to outstanding Options are exchanged for, converted into, or
otherwise become (whether or not pursuant to a Transfer of Control (as defined
below)) shares of another corporation (the "New Shares"), the Company may
unilaterally amend the outstanding Options to provide that such Options are
exercisable for New Shares In the event of any such amendment, the number of
shares and the exercise price of the outstanding Options shall be adjusted in a
fair and equitable manner.

            11. Transfer of Control. 

A "TRANSFER OF CONTROL" shall be deemed to have occurred in the event any of 
the following occurs with respect to the Company.

                 (a)      the direct or indirect sale or exchange by the
stockholders of the Company of all or substantially all of the stock of the
Company where the stockholders of the Company before such sale or exchange do
not retain, directly or indirectly, at least a majority of the beneficial
interest in the voting stock of the Acquiring Corporation as defined below
after such sale or exchange;

                 (b)      a merger or consolidation where the stockholders of
the Company before such merger or consolidation do not retain, directly or
indirectly, at least a majority of the beneficial interest in the voting stock
of the Acquiring Corporation as defined below after such merger or
consolidation;

                 (c)      the sale, exchange, or transfer of all or
substantially all of the assets of the Company (other than a sale, exchange, or
transfer to one (1) or more subsidiary corporations (as defined in paragraph 1
above) of the Company); or

                 (d)      a liquidation or dissolution of the Company.

         Thirty (30) days prior the proposed effective date of any Transfer of
Control. each Optionee under a stock option agreement outstanding for 335 days
or more shall be credited, as of the proposed effective date of the Transfer of
Control, and if still employed by the Company on that date, with 100% of such
shares, for purposes of determining the percentage of shares which shall be
immediately exercisable and/or fully vested under each such stock option
agreement. Other options, except as set forth below, shall not be affected.

         Furthermore, in the event of a Transfer of Control, the surviving,
continuing successor, or purchasing corporation or parent corporation thereof,
as the case may be (the "Acquiring Corporation"), shall either assume the
Company's rights and obligations under outstanding stock option agreements or
substitute options for the Acquiring Corporation's stock for such outstanding
Options. In the event the Acquiring Corporation elects not to assume or
substitute for such outstanding Options in connection with the Transfer of
Control. any unexercisable and/or unvested shares subject to such outstanding
stock option agreements shall be immediately exercisable and fully vested as of
the date thirty (30) days prior to the proposed effective date of the Transfer
of
   6
Control. The exercise and/or vesting of any Option that was permissible solely
by reason of this paragraph 11 shall be conditioned upon the consummation of
the Transfer of Control. Any Options which are neither assumed or substituted
for by the Acquiring Corporation in connection with the Transfer of Control nor
exercised as of the date of the Transfer of Control shall terminate and cease
to be outstanding effective as of the date of the Transfer of Control.

            12. Provision of Information. Each Optionee shall be given access
to information concerning the Company equivalent to that information generally
made available to the Company's common stockholders generally.

            13. Options Non-Transferable. During the lifetime of the Optionee,
the Option shall be exercisable only by the Optionee.  No Option shall be
assignable or transferable by the Optionee, except by will or by the laws of
descent and distribution.

            14. Termination or Amendment of Plan or Options. The Board,
including any duly appointed committee of the Board, may terminate or amend the
Plan or any Option at any time; provided, however, that without the approval of
the Company's stockholders, there shall be (a) no increase in the total number
of shares of Stock covered by the Plan (except by operation of the provisions
of paragraph 10 above), (b) no change in the class eligible to receive
Incentive Stock Options and (c) no expansion in the class eligible to receive
non-statutory stock options. In addition to the foregoing, the approval of the
Company's stockholders shall be sought for any amendment to the Plan for which
the Board deems stockholder approval necessary in order to comply with Rule
16b-3. In any event, no amendment may adversely affect any then outstanding
Option or any unexercised portion thereof, without the consent of the Optionee,
unless such amendment is required to enable an Option designated as an
Incentive Stock Option to qualify as an Incentive Stock Option.

                  IN WITNESS WHEREOF, the undersigned Assistant Secretary of
the Company certifies that the foregoing Ciena Corporation Amended and Restated
1994 Stock Option Plan was duly adopted by the Board of Directors of the
Company on the ___ day of August, 1994.

This Option is intended to be an incentive stock option as described in section 422 of the Code, but the Company does not represent or warrant that this Option qualifies as such. The Optionee should consult with the Optionee's own tax advisors regarding the tax effects of this Option and the requirements necessary to obtain favorable income tax treatment under section 422 of the Code, including, but not limited to, holding period requirements. 3. Administration. All questions of interpretation concerning this Option Agreement shall be determined by the Board of Directors of the Company (the "BOARD") and/or by a duly appointed committee of the Board having such powers as shall be specified by the Board. Any subsequent references herein to the Board shall also mean the committee if such committee has been appointed and, unless the powers of the committee have been specifically limited, the committee shall have all of the powers of the Board granted in the Plan, including, without limitation, the power to terminate or amend the Plan at any time, subject to the terms of the Plan and any applicable limitations imposed by law.

Any officer of a Participating Company shall have the authority to act on behalf of the Company with respect to any matter, right, obligation, or election which is the responsibility of or which is allocated to the Company herein, provided the officer has apparent authority with respect to such matter, right, obligation, or election. 4. Exercise of the Option. (a) Right to Exercise. The Option shall be first exercisable on and after the Initial Vesting Date, and then only to the extent vested. Notwithstanding the foregoing, except as provided in paragraph 16, the aggregate fair market value of the stock with respect to which the Optionee may exercise the Option for the first time during any calendar year, together with any other incentive stock options which are exercisable for the first time during any such year, as determined in accordance with section 422(d) of the Code, shall not exceed One Hundred Thousand Dollars ($100,000). Such limitation on exercise described in section 422(d) of the Code shall be referred to in this Option Agreement as the "$100,000 EXERCISE LIMITATION". Furthermore, notwithstanding the foregoing, the Option may be exercised only in multiples of one hundred (100) shares unless all shares subject to the Option are being exercised; provided, however, that the foregoing restriction shall not apply so as to prevent an exercise (i) following the Optionee's termination of employment as set forth in paragraph 7 below or (ii) during the thirty (30) day periods immediately preceding and following an Ownership Change as defined in paragraph 8 below. In addition to the foregoing, in the event that the adoption of the Plan or any amendment of the Plan is subject to the approval of the Company's stockholders in order for the Option to comply with the requirements of Rule 16b-3, promulgated under the Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT"), the Option shall not be exercisable prior to such stockholder -3- 4 approval if the Optionee is subject to Section 16(b) of the Exchange Act, unless the Board, in its sole discretion, approves the exercise of the Option prior to such stockholder approval. (b) Method of Exercise. Exercise of the Option must be by written notice to the Company which must state the election to exercise the Option, the number of shares for which the Option is being exercised and such other representations and agreements as to the Optionee's investment intent with respect to such shares as may be required pursuant to the provisions of this Option Agreement. The written notice must be signed by the Optionee and must be delivered in person, by certified or registered mail, return receipt requested, or by facsimile transmission, to the Chief Financial Officer of the Company, or other authorized representative of the Participating Company Group, prior to the termination of the Option as set forth in paragraph 6 below, accompanied by (i) full payment of the exercise price for the number of shares being purchased and (ii) an executed copy, if required herein, of the then current forms of escrow and security agreements referenced below. (c) Payment of Exercise Price. (i) Forms of Payment Authorized. Payment of the exercise price for the number of shares for which the Option is being exercised shall be made (A) in cash, by check, or cash equivalent; (B) by tender to the Company of shares of the Company's common stock owned by the Optionee having a fair market value, as determined by the Board, not less than the exercise price, which either have been owned by the Optionee for more than six (6) months or were not acquired, directly or indirectly, from the Company; (C) if expressly authorized by the Company at the time of Option exercise, in its sole discretion, by the Optionee's recourse promissory note in a form approved by the Company; (D) by Immediate Sales Proceeds, as defined below; (E) by any combination of the foregoing. (ii) Tender of Company Stock. Notwithstanding the foregoing, the Option may not be exercised by tender to the Company of shares of the Company's common stock to the extent such tender of stock would constitute a violation of the provisions of any law, regulation and/or agreement restricting the redemption of the Company's common stock or, if in the opinion of Company counsel, might impair the ability of purchasers of stock from the Company from taking full advantage of the provisions of Section 1202 of the Code relating to capital gains treatment of stock issued by the Company. Unless otherwise provided by the Board, an Option may not be exercised by tender to the Company of shares of the Company's common stock unless such shares of the Company's -4- 5 stock either have been owned by the Optionee for more than six (6) months or were not acquired, directly or indirectly, from the Company. (iii) Promissory Note. Unless otherwise specified by the Board at the time the Option is granted, a promissory note permitted in accordance with clause (c)(i)(C) above shall not exceed the amount permitted by law to be paid by a promissory note and shall be a full recourse note in a form satisfactory to the Company, with principal payable four (4) years after the date the Option is exercised. Interest on the principal balance of the promissory note shall be payable in annual installments at the minimum interest rate necessary to avoid imputed interest pursuant to all applicable sections of the Code. Such recourse promissory note shall be secured by the shares of stock acquired pursuant to the then current form of security agreement as approved by the Company. In the event the Company at any time is subject to the regulations promulgated by the Board of Governors of the Federal Reserve System or any other governmental entity affecting the extension of credit in connection with the Company's securities, any promissory note shall comply with such applicable regulations, and the Optionee shall pay the unpaid principal and accrued interest, if any, to the extent necessary to comply with such applicable regulations. Except as the Company in its sole discretion shall determine, the Optionee shall pay the unpaid principal balance of the promissory note and any accrued interest thereon upon termination of the Optionee's employment with the Participating Company Group for any reason, with or without cause. (iv) Immediate Sales Proceeds. "IMMEDIATE SALES PROCEEDS" shall mean the assignment in form acceptable to the Company of the proceeds of a sale of some or all of the shares acquired upon the exercise of the Option pursuant to a program and/or procedure approved by the Company (including, without limitation, through an exercise complying with the provisions of Regulation T as promulgated from time to time by the Board of Governors of the Federal Reserve System). The Company reserves, at any and all times, the right, in the Company's sole and absolute discretion, to decline to approve any such program and/or procedure. (d) Tax Withholding. At the time the Option is exercised, in whole or in part, or at any time thereafter as requested by the Company, the Optionee hereby authorizes payroll withholding and otherwise agrees to make adequate provision for foreign, federal and state tax withholding obligations of the Company, if any, which arise in connection with the Option, including, without limitation, obligations arising upon (i) the exercise, in whole or in part, of the Option, (ii) the transfer, in whole or in part, of any shares acquired on exercise of the Option, or (iii) the operation of any law or regulation providing for the imputation of interest, or (iv) the lapsing of any restriction with respect to any shares acquired on exercise of the Option. The Optionee is cautioned that the Option is not exercisable unless the Company's withholding obligations are satisfied. Accordingly, the Optionee may not be able to exercise the Option when desired even though the Option is vested and the Company shall have no obligation to issue a certificate for such shares. -5- 6 (e) Certificate Registration. Except in the event the exercise price is paid by Immediate Sales Proceeds, the certificate or certificates for the shares as to which the Option is exercised shall be registered in the name of the Optionee, or, if applicable, the heirs of the Optionee. (f) Restrictions of Grant of the Option and Issuance of Shares. The grant of the Option and the issuance of the shares upon exercise of the Option shall be subject to compliance with all applicable requirements of federal, state or foreign law with respect to such securities. The Option may not be exercised if the issuance of shares upon such exercise would constitute a violation of any applicable federal, state, or foreign securities laws or other law or regulations. In addition, the Option may not be exercised unless (i) a registration statement under the Securities Act of 1933, as amended (the "SECURITIES ACT"), shall at the time of exercise of the Option be in effect with respect to the shares issuable upon exercise of the Option or (ii) in the opinion of legal counsel to the Company, the shares issuable upon exercise of the Option may be issued in accordance with the terms of an applicable exemption from the registration requirements of the Securities Act. THE OPTIONEE IS CAUTIONED THAT THE OPTION MAY NOT BE EXERCISABLE UNLESS THE FOREGOING CONDITIONS ARE SATISFIED. ACCORDINGLY, THE OPTIONEE MAY NOT BE ABLE TO EXERCISE THE OPTION WHEN DESIRED EVEN THOUGH THE OPTION IS VESTED. Questions concerning this restriction should be directed to the Chief Financial Officer of the Company. As a condition to the exercise of the Option, the Company may require the Optionee to satisfy any qualifications that may be necessary or appropriate, to evidence compliance with any applicable law or regulation and to make any representation or warranty with respect thereto as may be requested by the Company. (g) Fractional Shares. The Company shall not be required to issue fractional shares upon the exercise of the Option. 5. Non-Transferability of the Option; Non-Alienation of Benefits. The Option may be exercised during the lifetime of the Optionee only by the Optionee and may not be assigned or transferred in any manner except by will or by the laws of descent and distribution. Following the death of the Optionee, the Option, to the extent unexercised and vested to the Optionee on the date of death, may be exercised by the Optionee's legal representative or by any person empowered to do so under the deceased Optionee's will or under the then applicable laws of descent and distribution. Except with the prior written consent of the Company, subject to the foregoing, or as otherwise provided herein, no right or benefit under this Option Agreement shall be subject to anticipation, alienation, sale, assignment, pledge, encumbrance or charge, and any attempt to anticipate, alienate, sell, assign, pledge, encumber or charge the same without such consent, if applicable, shall be void. Except with such consent, no right or benefit under this Option Agreement shall in any manner be liable for or subject to the debts, contacts, liabilities or torts of the person entitled to such benefit. Except to the extent previously approved by the Company in writing, or as otherwise provided herein, if the Optionee should become bankrupt or attempt to anticipate, alienate, sell, assign, pledge, encumber or charge any right or benefit -6- 7 hereunder, then such right or benefit shall cease and terminate, and in such event, the Company may hold or apply the same or any part thereof for the benefit of the Optionee, the Optionee's spouse, children or other dependents, or any of them, in such manner and in such proportion as the Company may in its sole determination deem proper. 6. Termination of the Option. The Option shall terminate and may no longer be exercised on the first to occur of (a) the Option Term Date as defined above, (b) the last date for exercising the Option following termination of employment as described in paragraph 7 below, or (c) a Transfer of Control to the extent provided in paragraph 8 below. 7. Termination of Employment. (a) Termination Other Than by Death or Disability. Except as otherwise provided below, if the Optionee ceases to be an employee of the Participating Company Group for any reason, except death or disability within the meaning of section 422(c) of the Code, the Option, to the extent unexercised and exercisable by the Optionee on the date on which the Optionee ceased to be an employee, may be exercised by the Optionee within thirty (30) days after the date on which the Optionee's employment terminated, but in any event no later than the Option Term Date. (b) Termination by Death or Disability. Except as otherwise provided below, if the Optionee's employment with the Company is terminated because of the death or disability of the Optionee within the meaning of section 422(c) of the Code, the Option, to the extent unexercised and exercisable by the Optionee on the date on which the Optionee ceased to be an employee, may be exercised by the Optionee (or the Optionee's legal representative) at any time prior to the expiration of twelve (12) months from the date on which the Optionee's employment terminated, but in any event no later than the Option Term Date. The Optionee's employment shall be deemed to have terminated on account of death if the Optionee dies within three (3) months after the Optionee's termination of employment. (c) Limitations on Exercise After Termination. Notwithstanding the provisions of paragraphs 7(a) and (b), the Option may not be exercised after the Optionee's termination of employment if the shares to be acquired on exercise of the Option would be Unvested Shares as that term is defined in paragraph 11 below. Except as provided in this paragraph 7, the Option shall terminate and may not be exercised after the Optionee ceases to be an employee of the Participating Company Group. Furthermore, the Board may at any time after the Optionee's termination of employment cancel the Option with respect to all or a portion of the shares otherwise remaining exercisable under the Option, if the Company finds or has found that the Optionee: (i) Engaged in willful, deliberate or gross misconduct toward the Company; (ii) Has violated the terms of any confidentiality agreement or obligation between the Optionee and the Company; or -7- 8 (iii) Has accepted employment with an entity which the Company determines is in a business that could result in compromising any confidentiality agreement or obligation between the Optionee and the Company. (d) Employee and Termination of Employment Defined. For purposes of this paragraph 7, the term "employee" shall mean any person, including officers and directors, employed by a Participating Company or performing services for a Participating Company as a director, consultant, advisor or other independent contractor. For purposes of this paragraph 7, the Optionee's employment shall be deemed to have terminated if the Optionee ceases to be employed by a Participating Company (whether upon an actual termination of employment or upon the Optionee's employer ceasing to be a Participating Company). The Optionee's employment shall not be deemed to have terminated merely because of a change in the capacity in which the Optionee serves as an employee, provided that there is no interruption or termination of the Optionee's service as an employee. (THE OPTIONEE IS CAUTIONED THAT IF THE OPTION IS EXERCISED MORE THAN THREE (3) MONTHS AFTER THE DATE ON WHICH THE OPTIONEE'S EMPLOYMENT (OTHER THAN AS A DIRECTOR, CONSULTANT, ADVISOR OR OTHER INDEPENDENT CONTRACTOR) TERMINATED, THE OPTION MAY CEASE TO BE AN INCENTIVE STOCK OPTION. THE OPTIONEE SHOULD CONSULT WITH THE OPTIONEE'S OWN TAX ADVISORS AS TO THE TAX CONSEQUENCES OF ANY SUCH DELAYED EXERCISE.) (e) Extension if Exercise Prevented by Law. Notwithstanding the foregoing, if the exercise of the Option within the applicable time periods set forth above is prevented by the provisions of paragraph 4(f) above, the Option shall remain exercisable until three (3) months after the date the Optionee is notified by the Company that the Option is exercisable, but in any event no later than the Option Term Date. The Company makes no representation as to the tax consequences of any such delayed exercise. The Optionee should consult with the Optionee's own tax advisors as to the tax consequences to the Optionee of any such delayed exercise. (f) Extension if Optionee Subject to Section 16(b). Notwithstanding the foregoing, if the exercise of the Option within the applicable time periods set forth above would subject the Optionee to suit under Section 16(b) of the Exchange Act, the Option shall remain exercisable until the earliest to occur of (i) the tenth (10th) day following the date on which the Optionee would no longer be subject to such suit, (ii) the one hundred and ninetieth (190th) day after the Optionee's termination of employment, or (iii) the Option Term Date. The Company makes no representation as to the tax consequences of any such delayed exercise. The Optionee should consult with the Optionee's own tax advisors as to the tax consequences to the Optionee of any such delayed exercise. (g) Leave of Absence. For purposes hereof, the Optionee's employment with the Participating Company Group shall not be deemed to terminate if the Optionee takes any military leave, sick leave, or other bona fide leave of absence approved by -8- 9 the Company of ninety (90) days or less. In the event of a leave in excess of ninety (90) days, the Optionee's employment shall be deemed to terminate on the ninety-first (91st) day of the leave unless the Optionee's right to re employment with the Participating Company Group remains guaranteed by statute or contract. Notwithstanding the foregoing, unless otherwise designated by the Company (or required by law) a leave of absence shall not be treated as employment for purposes of determining the Optionee's Vested Percentage. 8. A "Transfer of Control" (a) A "TRANSFER OF CONTROL" shall be deemed to have occurred in the event any of the events described in Paragraph 11 of the Plan occurs with respect to the Company. (b) In the event of Transfer of Control, the surviving, continuing, successor, or purchasing corporation or parent corporation thereof, as the case may be (the "ACQUIRING CORPORATION"), shall either assume the Company's rights and obligations under this Option Agreement or substitute an option for the Acquiring Corporation's stock for the Option. In the event the Acquiring Corporation elects not to assume the Company's rights and obligations under this Option Agreement or substitute an option for the Acquiring Corporation's stock for the Option, all shares subject to this Option Agreement shall become Vested Shares (as defined in paragraph 11(b) below) effective as of the date thirty (30) days prior to the Proposed Effective Date. (c) The exercise and/or vesting of any shares that was permissible solely by reason of this paragraph 8 shall be conditioned upon the consummation of the Transfer of Control. The Option shall terminate and cease to be outstanding effective upon the Transfer of Control to the extent that the Option is neither assumed or substituted for by the Acquiring Corporation in connection with the Transfer of Control nor exercised as of the date of the Transfer of Control. 9. Effect of Change in Stock Subject to the Option. Appropriate adjustments shall be made in the number, exercise price and class of shares of stock subject to the Option in the event of a stock dividend, stock split, reverse stock split, recapitalization, combination, reclassification, or like change in the capital structure of the Company. In the event a majority of the shares which are of the same class as the shares that are subject to the Option are exchanged for, converted into, or otherwise become (whether or not pursuant to an Ownership Change) shares of another corporation (the "NEW SHARES"), the Company may unilaterally amend the Option to provide that the Option is exercisable for New Shares. In the event of any such amendment, the number of shares and the exercise price shall be adjusted in a fair and equitable manner. 10. Rights as a Stockholder or Employee. The Optionee shall have no rights as a stockholder with respect to any shares covered by the Option until the date of the issuance of a certificate or certificates for the shares for which the Option has been exercised. No adjustment shall be made for dividends or distributions or other rights for which the record -9- 10 date is prior to the date such certificate or certificates are issued, except as provided in paragraph 9 above. Nothing in the Option shall confer upon the Optionee any right to continue in the employ of a Participating Company or interfere in any way with any right of the Participating Company Group to terminate the Optionee's employment at any time. 11. Right of First Refusal. (a) Right of First Refusal. Except as provided in paragraph 11(g) below, in the event the Optionee proposes to sell, pledge, or otherwise transfer any Vested Shares (the "TRANSFER SHARES") to any person or entity, including, without limitation, any stockholder of the Participating Company Group, the Company shall have the right to repurchase the Transfer Shares under the terms and subject to the conditions set forth in this paragraph 12 (the "RIGHT OF FIRST REFUSAL"). (b) Notice of Proposed Transfer. Prior to any proposed transfer of the Transfer Shares, the Optionee shall give a written notice (the "TRANSFER NOTICE") to the Company describing fully the proposed transfer, including the number of Transfer Shares, the name and address of the proposed transferee (the "PROPOSED TRANSFEREE") and, if the transfer is voluntary, the proposed transfer price and containing such information necessary to show the bona fide nature of the proposed transfer. In the event of a bona fide gift or involuntary transfer, the proposed transfer price shall be deemed to be the fair market value of the Transfer Shares as determined by the Company in good faith. In the event the Optionee proposes to transfer any Transfer Shares to more than one (1) Proposed Transferee, the Optionee shall provide a separate Transfer Notice for the proposed transfer to each Proposed Transferee. The Transfer Notice shall be signed by both the Optionee and the Proposed Transferee and must constitute a binding commitment of the Optionee and the Proposed Transferee for the transfer of the Transfer Shares to the Proposed Transferee subject only to the Right of First Refusal. (c) Bona Fide Transfer. In the event that the Company shall determine that the information provided by the Optionee in the Transfer Notice is insufficient to establish the bona fide nature of a proposed voluntary transfer, the Company shall give the Optionee written notice of the Optionee's failure to comply with the procedure described in this paragraph 12 and the Optionee shall have no right to transfer the Transfer Shares without first complying with the procedure described in this paragraph 12. The Optionee shall not be permitted to transfer the Transfer Shares if the proposed transfer is not bona fide. (d) Exercise of Right of First Refusal. In the event the proposed transfer is deemed to be bona fide, the Company shall have the right to purchase all, but not less than all, of the Transfer Shares (except as the Company and the Optionee otherwise agree) at the purchase price and on the terms set forth in the Transfer Notice by delivery to the Optionee of a notice of exercise of the Right of First Refusal within thirty (30) days after the date the Transfer Notice is delivered to the Company. The Company's exercise or failure to exercise the Right of First Refusal with respect to any proposed transfer described in a Transfer Notice shall not affect the Company's right to exercise the Right of First Refusal with respect to any proposed transfer described in any other Transfer Notice, whether or not -10- 11 such other Transfer Notice is issued by the Optionee or issued by a person other than the Optionee with respect to a proposed transfer to the same Proposed Transferee. If the Company exercises the Right of First Refusal, the Company and the Optionee shall thereupon consummate the sale of the Transfer Shares to the Company on the terms set forth in the Transfer Notice within sixty (60) days after the date the Transfer Notice is delivered to the Company (unless a longer period is offered by the Proposed Transferee); provided, however, that in the event the Transfer Notice provides for the payment for the Transfer Shares by the present value cash equivalent of the consideration described in the Transfer Notice as reasonably determined by the Company. For purposes of the foregoing, cancellation of any indebtedness of the Optionee to any Participating Company shall be treated as payment to the Optionee in cash to the extent of the unpaid principal and any accrued interest canceled. (e) Failure to Exercise Right of First Refusal. If the Company fails to exercise the Right of First Refusal in full within the period specified in paragraph 11(d) above, the Optionee may conclude a transfer to the Proposed Transferee of the Transfer Shares on the terms and conditions described in the Transfer Notice, provided such transfer occurs not later than ninety (90) days following delivery to the Company of the Transfer Notice. The Company shall have the right to demand further assurances from the Optionee and the Proposed Transferee (in a form satisfactory to the Company) that the transfer of the Transfer Shares was actually carried out on the terms and conditions described in the Transfer Notice. No Transfer Shares shall be transferred on the books of the Company until the Company has received such assurances, if so demanded, and has approved the proposed transfer as bona fide. Any proposed transfer on terms and conditions different from those described in the Transfer Notice, as well as any subsequent proposed transfer by the Optionee, shall again be subject to the Right of First Refusal and shall require compliance by the Optionee with the procedure described in this paragraph 11. (f) Transferees of Transfer Shares. All transferees of the Transfer Shares or any interest therein, other than the Company, shall be required as a condition of such transfer to agree in writing (in a form satisfactory to the Company) that such transferee shall receive and hold such Transfer Shares or interests subject to the provisions of this paragraph 11 providing for the Right of First Refusal with respect to any subsequent transfer. Any sale or transfer of any shares acquired upon exercise of the Option shall be void unless the provisions of this paragraph 11 are met. (g) Transfers Not Subject to Right of First Refusal. Notwithstanding the foregoing, the Right of First Refusal shall not apply to any transfer or exchange of the shares acquired pursuant to the exercise of the Option if such transfer or exchange is in connection with an Ownership Change. If the consideration received pursuant to such transfer or exchange consists of stock of a Participating Company, such consideration shall remain subject to the Right of First Refusal unless the provisions of paragraph 11(i) below result in a termination of the Right of First Refusal. Furthermore, notwithstanding the foregoing, the Right of First Refusal shall not apply to a transfer of Transfer Shares to the Optionee's ancestors, descendants, or spouse or to a trustee solely for the benefit of the Optionee or Optionee's ancestors, descendants, or spouse, or to a charitable institution; -11- 12 provided, however, that such transferee shall agree in writing (in a form satisfactory to the Company) to take the stock subject to all the terms and conditions of this paragraph 12 providing for a Right of First Refusal with respect to any subsequent transfer. (h) Assignment of Right of First Refusal. The Company shall have the right to assign the Right of First Refusal at any time, whether or not the Optionee has attempted a transfer, to one (1) or more persons as may be selected by the Company. (i) Early Termination of Right of First Refusal. The other provisions of this paragraph 11 notwithstanding, the Right of First Refusal shall terminate, and be of no further force and effect, upon (i) the occurrence of a Transfer of Control, unless the surviving, continuing, successor, or purchasing corporation or parent corporation thereof, as the case may be, assumes the Company's rights and obligations under the Plan, or (ii) the existence of a public market for the class of shares subject to the Right of First Refusal. A "public market" shall be deemed to exist if (x) such stock is listed on a national securities exchange (as that term is used in the Exchange Act) or (y) such is traded on the over-the-counter market and prices therefor are published daily on business days in a recognized financial journal. 12. Escrow. (a) Establishment of Escrow. To ensure that shares subject to the Right of First Refusal and/or security for any promissory note will be available for purchase, the Company may require the Optionee to deposit the certificate or certificates evidencing the shares which the Optionee purchases upon exercise of the Option with the Company or other escrow agent designated by the Company under the terms and conditions of escrow and security agreements approved by the Company. If the Company does not require such deposit as a condition of exercise of the Option, or if the Company releases the certificate or certificates from escrow prior to the lapsing of all such restrictions and/or security interest, the Company reserves the right at any time to require the Optionee to so deposit the certificates in escrow. The Company shall bear the expenses of the escrow. (b) Delivery of Shares to Optionee. As soon as practicable after the expiration of the Right of First Refusal, and after full repayment on any promissory note secured by the shares in escrow, the escrow agent shall deliver to the Optionee the shares no longer subject to such restrictions and no longer security for any promissory note. (c) Notices and Payments. In the event the shares held in escrow are subject to the Company's exercise of the Right of First Refusal, the notices required to be given to the Optionee shall be given to the escrow agent any payment required to be given to the Optionee shall be given to the escrow agent. Within thirty (30) days after payment by the Company, the escrow agent shall deliver the shares which the Company has purchased to the Company and shall deliver the payment received from the Company to the Optionee. -12- 13 13. Stock Dividends Subject to Option Agreement. If, from time to time, there is any stock dividend, stock split, or other change in the character or amount of any of the outstanding stock of the corporation the stock of which is subject to the provisions of this Option Agreement, then in such event any and all new, substituted or additional securities to which the Optionee is entitled by reason of the Optionee's ownership of the shares acquired upon exercise of the Option shall be immediately subject to the Right of First Refusal, and/or any security interest held by the Company with the same force and effect as the shares subject to the Right of First Refusal, and such security interest immediately before such event. 14.

The Option shall be immediately exercisable in its entirety on and after the Initial Exercise Date subject to the Optionee's agreement that any shares purchased upon exercise are subject to the Company's repurchase rights set forth in paragraph 11 and paragraph 12 below. Notwithstanding the foregoing, the Option may be exercised only in multiples of one hundred (100) shares unless all shares subject to the Option are being exercised; provided, however, that the foregoing restriction shall not apply so as to prevent an exercise (i) following the Optionee's termination of employment as set forth in paragraph 7 below or (ii) during the thirty (30) day periods immediately preceding and following an Ownership Change as defined in paragraph 8 below.

(ii) Tender of Company Stock. Notwithstanding the foregoing, the Option may not be exercised by tender to the Company of shares of the Company's common stock to the extent such tender of stock would constitute a violation of the provisions of any law, regulation and/or agreement restricting the redemption of the Company's common stock. (iii) Promissory Note. Unless otherwise specified by the Board at the time the Option is granted, a promissory note permitted in accordance with clause (c)(i)(C) above shall not exceed the amount permitted by law to be paid by a promissory note and shall be a full recourse note in a form satisfactory to the Company, with principal payable four (4) years after the date the Option is exercised. Interest on the principal balance of the promissory note shall be payable in annual installments at the minimum interest rate necessary to avoid imputed interest pursuant to all applicable sections of the Code. Such recourse promissory note shall be secured by the shares of stock acquired pursuant to the then current form of security agreement as approved by the Company. In the event the Company at any time is subject to the regulations promulgated by the Board of Governors of the Federal Reserve System or any other governmental entity affecting the extension of credit in connection with the Company's securities, any promissory note shall comply with such applicable regulations, and the Optionee shall pay the unpaid principal and accrued interest, if any, to the extent necessary to comply with such applicable regulations. Except as the Company in its sole discretion shall determine, the Optionee shall pay the unpaid principal balance of the promissory note and any accrued interest thereon upon termination of the Optionee's employment with the Participating Company Group for any reason, with or without cause. 4 22 (iv) Immediate Sales Proceeds. "IMMEDIATE SALES PROCEEDS" shall mean the assignment in form acceptable to the Company of the proceeds of a sale of some or all of the shares acquired upon the exercise of the Option pursuant to a program and/or procedure approved by the Company (including, without limitation, through an exercise complying with the provisions of Regulation T as promulgated from time to time by the Board of Governors of the Federal Reserve System). The Company reserves, at any and all times, the right, in the Company's sole and absolute discretion, to decline to approve any such program and/or procedure. (d) Tax Withholding. At the time the Option is exercised, in whole or in part, or at any time thereafter as requested by the Company, the Optionee hereby authorizes payroll withholding and otherwise agrees to make adequate provision for foreign, federal and state tax withholding obligations of the Company, if any, which arise in connection with the Option, including, without limitation, obligations arising upon (i) the exercise, in whole or in part, of the Option, (ii) the transfer, in whole or in part, of any shares acquired on exercise of the Option, or (iii) the operation of any law or regulation providing for the imputation of interest, or (iv) the lapsing of any restriction with respect to any shares acquired on exercise of the Option. The Optionee is cautioned that the Option is not exercisable unless the Company's withholding obligations are satisfied.

(e) Certificate Registration. Except in the event the exercise price is paid by Immediate Sales Proceeds, the certificate or certificates for the shares as to which the Option is exercised shall be registered in the name of the Optionee, or, if applicable, the heirs of the Optionee. (f) Restrictions on Grant of the Option and Issuance of Shares. The grant of the Option and the issuance of shares upon exercise of the Option shall be subject to compliance with all applicable requirements of federal, state or foreign law with respect to such securities. The Option may not be exercised if the issuance of shares upon such exercise would constitute a violation of any applicable federal, state or foreign securities laws or other law or regulations. In addition, the Option may not be exercised unless (i) a registration statement under the Securities Act of 1933, as amended (the "SECURITIES ACT"), shall at the time of exercise of the Option be in effect with respect to the shares issuable upon exercise of the Option, or (ii) in the opinion of legal counsel to the Company, the shares issuable upon exercise of the Option may be issued in accordance with the terms of an applicable exemption from the registration requirements of the Securities Act. THE OPTIONEE IS CAUTIONED THAT THE OPTION MAY NOT BE EXERCISABLE UNLESS THE FOREGOING CONDITIONS ARE SATISFIED. ACCORDINGLY, THE OPTIONEE MAY NOT BE ABLE TO EXERCISE THE OPTION WHEN DESIRED EVEN THOUGH THE OPTION IS VESTED. Questions concerning this restriction should be directed to the Chief Financial Officer of the Company. As a condition to the exercise of the Option, the Company may require the Optionee to satisfy any qualifications that may be necessary or appropriate, to evidence compliance with any applicable law or regulation, and to make any representation or warranty with respect thereto as may be requested by the Company. 5 23 (g) Fractional Shares. The Company shall not be required to issue fractional shares upon the exercise of the Option. 5. Non-Transferability of the Option; Non-Alienation of Benefits. The Option may be exercised during the lifetime of the Optionee only by the Optionee and may not be assigned or transferred in any manner except by will or by the laws of descent and distribution. Following the death of the Optionee, the Option, to the extent unexercised and exercisable by the Optionee on the date of death, may be exercised by the Optionee's legal representative or by any person empowered to do so under the deceased Optionee's will or under the then applicable laws of descent and distribution. Except with the prior written consent of the Company, subject to the foregoing, or as otherwise provided herein, no right or benefit under this Option Agreement shall be subject to anticipation, alienation, sale, assignment, pledge, encumbrance or charge, and any attempt to anticipate, alienate, sell, assign, pledge, encumber or charge the same without such consent, if applicable, shall be void. Except with such consent, no right or benefit under this Option Agreement shall in any manner be liable for or subject to the debts, contracts, liabilities or torts of the person entitled to such benefit. Except to the extent previously approved by the Company in writing, or as otherwise provided herein, if the Optionee should become bankrupt or attempt to anticipate, alienate, sell, assign, pledge, encumber or charge any right or benefit hereunder, then such right or benefit shall cease and terminate, and in such event, the Company may hold or apply the same or any part thereof for the benefit of the Optionee, the Optionee's spouse, children or other dependents, or any of them, in such manner and in such proportion as the Company may in its sole determination deem proper. 6. Termination of the Option. The Option shall terminate and may no longer be exercised on the first to occur of (a) the Option Term Date as defined above, (b) the last date for exercising the Option following termination of employment as described in paragraph 7 below, or (c) a Transfer of Control to the extent provided in paragraph 8 below. 7. Termination of Employment. (a) Termination Other Than by Death or Disability. Except as otherwise provided below, if the Optionee ceases to be an employee of the Participating Company Group for any reason, except death or disability within the meaning of section 422(c) of the Code, the Option, to the extent unexercised and exercisable by the Optionee on the date on which the Optionee ceased to be an employee, may be exercised by the Optionee within thirty (30) days after the date on which the Optionee's employment terminated, but in any event no later than the Option Term date. (b) Termination by Death or Disability. Except as otherwise provided below, if the Optionee's employment with the Company is terminated because of the death or disability of the Optionee within the meaning of section 422(c) of the Code, the Option, to the extent unexercised and exercisable by the Optionee on the date on which the Optionee ceased to be an employee, may be exercised by the Optionee (or the Optionee's legal representative) at any time 6 24 prior to the expiration of twelve (12) months from the date on which the Optionee's employment terminated, but in any event no later than the Option Term Date. The Optionee's employment shall be deemed to have terminated on account of death if the Optionee dies within three (3) months after the Optionee's termination of employment. (c) Limitations on Exercise After Termination. Notwithstanding the provisions of paragraphs 7(a) and (b), the Option may not be exercised after the Optionee's termination of employment if the shares to be acquired on exercise of the Option would be Unvested Shares as that term is defined in paragraph 11 below. Except as provided in this paragraph 7, the Option shall terminate and may not be exercised after the Optionee ceases to be an employee of the Participating Company Group. Furthermore, the Board may at any time after the Optionee's termination of employment cancel the Option with respect to all or a portion of the shares otherwise remaining exercisable under the Option, if the Company finds or has found that the Optionee: (i) Engaged in willful, deliberate or gross misconduct toward the Company; (ii) Has violated the terms of any confidentiality agreement or obligation between the Optionee and the Company; or (iii) Has accepted employment with an entity which the Company determines is in a business that could result in compromising any confidentiality agreement or obligation between the Optionee and the Company. (d) Employee and Termination of Employment Defined. For purposes of this paragraph 7, the term "EMPLOYEE" shall mean any person, including officers and directors, employed by a Participating Company or performing services for a Participating Company as a director, consultant, advisor or other independent contractor. For purposes of this paragraph 7, the Optionee's employment shall be deemed to have terminated if the Optionee ceases to be employed by a Participating Company (whether upon an actual termination of employment or upon the Optionee's employer ceasing to be a Participating Company). The Optionee's employment shall not be deemed to have terminated merely because of a change in the capacity in which the Optionee serves as an employee, provided that there is no interruption or termination of the Optionee's service as an employee. (e) Extension if Exercise Prevented by Law. Notwithstanding the foregoing, if the exercise of the Option within the applicable time periods set forth above is prevented by the provisions of paragraph 4(f) above, the Option shall remain exercisable until three (3) months after the date the Optionee is notified by the Company that the Option is exercisable, but in any event no later than the Option Term Date. (f) Extension if Optionee Subject to Section 16(b). Notwithstanding the foregoing, if the exercise of the Option within the applicable time periods set forth above would subject the Optionee to suit under Section 16(b) of the Exchange Act, the Option shall remain exercisable until the earliest to occur of (i) the tenth (10th) day following the date on which the 7 25 Optionee would no longer be subject to such suit, (ii) the one hundred and ninetieth (190th) day after the Optionee's termination of employment, or (iii) the Option Term Date. (g) Leave of Absence. For purposes hereof, the Optionee's employment with the Participating Company Group shall not be deemed to terminate if the Optionee takes any military leave, sick leave, or other bona fide leave of absence approved by the Company of ninety (90) days or less. In the event of a leave in excess of ninety (90) days, the Optionee's employment shall be deemed to terminate on the ninety-first (91st) day of the leave unless the Optionee's right to reemployment with the Participating Company Group remains guaranteed by statute or contract. Notwithstanding the foregoing, unless otherwise designated by the Company (or required by law) a leave of absence shall not be treated as employment for purposes of determining the Optionee's Vested Percentage. 8. A Transfer of Control. (a) A "TRANSFER OF CONTROL" shall be deemed to have occurred in the event any of the events described in paragraph 11 of the Plan occurs with respect to the Company. (b) In the event of a Transfer of Control, the surviving, continuing, successor, or purchasing corporation or parent corporation thereof, as the case may be (the "ACQUIRING CORPORATION"), shall either assume the Company's rights and obligations under this Option Agreement or substitute an option for the Acquiring Corporation's stock for the Option. In the event the Acquiring Corporation elects not to assume the Company's rights and obligations under this Option Agreement or substitute an option for the Acquiring Corporation's stock for the Option, all shares subject to this Option Agreement shall become Vested Shares (as defined in paragraph 11(b) below) effective as of the date thirty (30) days prior to the Proposed Effective Date. (c) The exercise and/or vesting of any shares that was permissible solely by reason of this paragraph 8 shall be conditioned upon the consummation of the Transfer of Control. The Option shall terminate and cease to be outstanding effective upon the Transfer of Control to the extent that the Option is neither assumed or substituted for by the Acquiring Corporation in connection with the Transfer of Control nor exercised as of the date of the Transfer of Control. 9. Effect of Change in Stock Subject to the Option. Appropriate adjustments shall be made in the number, exercise price, and class of shares of stock subject to the Option in the event of a stock dividend, stock split, reverse stock split, recapitalization, combination, reclassification, or like change in the capital structure of the Company. In the event a majority of the shares which are of the same class as the shares that are subject to the Option are exchanged for, converted into, or otherwise become (whether or not pursuant to an Ownership Change) shares of another corporation (the "NEW SHARES"), the Company may unilaterally amend the Option to provide that the Option is exercisable for New Shares. In the event of any such amendment, the number of shares and the exercise price shall be adjusted in a fair and equitable manner. 8 26 10. Rights as a Stockholder or Employee. The Optionee shall have no rights as a stockholder with respect to any shares covered by the Option until the date of the issuance of a certificate or certificates for the shares for which the Option has been exercised. No adjustment shall be made for dividends or distributions or other rights for which the record date is prior to the date such certificate or certificates are issued, except as provided in paragraph 9 above. Nothing in the Option shall confer upon the Optionee any right to continue in the employ of a Participating Company or interfere in any way with any right of the Participating Company Group to terminate the Optionee's employment at any time. 11. Unvested Share Repurchase Option. (a) Unvested Share Repurchase Option. In the event the Optionee's employment with the Participating Company Group is terminated for any reason, with or without cause, or if the Optionee or the Optionee's legal representative attempts to sell, exchange, transfer, pledge, or otherwise dispose of (other than pursuant to an Ownership Change) any shares acquired upon exercise of the Option which exceed the Optionee's Vested Shares as defined in paragraph 11(b) below (the "UNVESTED SHARES"), the Company shall have the right to repurchase the Unvested Shares under the terms and subject to the conditions set forth in this paragraph 11 (the "UNVESTED SHARE REPURCHASE OPTION"). (b) Vested Shares and Unvested Shares Defined. On any given date, the number of "VESTED SHARES" shall be equal to the Number of Option Shares multiplied by the Vested Percentage determined as of such date pursuant to paragraph 1(f) above and rounded down to the nearest whole share. On such date, the number of Unvested Shares shall be equal to the Number of Option Shares reduced by the number of Vested Shares determined as of such date. (c) Exercise of Unvested Share Repurchase Option. The Company may exercise the Unvested Share Repurchase Option by written notice to the Optionee within six (6) months after (i) such termination of employment (or exercise of the Option, if later), or (ii) the Company has received notice of the attempted disposition. If the Company fails to give notice within such six (6) month period, the Unvested Share Repurchase Option shall terminate unless the Company and the Optionee have extended the time for the exercise of the Unvested Share Repurchase Option. The Unvested Share Repurchase Option must be exercised, if at all, for all of the Unvested Shares, except as the Company and the Optionee otherwise agree. (d) Payment for Shares and Return of Shares. Payment by the Company to the Optionee shall be made in cash within thirty (30) days after the date of the mailing of the written notice of exercise of the Unvested Share Repurchase Option. For purposes of the foregoing, cancellation of any indebtedness of the Optionee to any Participating Company shall be treated as payment to the Optionee in cash to the extent of the unpaid principal and any accrued interest canceled. The purchase price per share being repurchased by the Company shall be an amount equal to the Optionee's original cost per share, as adjusted pursuant to paragraph 9 above (the "REPURCHASE PRICE"). The shares being repurchased shall be delivered to the Company by the Optionee at the same time as the delivery of the Repurchase Price to the Optionee. 9 27 (e) Assignment of Unvested Share Repurchase Option. The Company shall have the right to assign the Unvested Share Repurchase Option at any time, whether or not such option is then exercisable, to one (1) or more persons as may be selected by the Company. (f) Ownership Change. In the event of an Ownership Change, any and all new, substituted or additional securities or other property to which the Optionee is entitled by reason of his or her ownership of Unvested Shares, determined after application of paragraph 8 above, shall be immediately subject to the Unvested Share Repurchase Option and included in the terms "shares" and "Unvested Shares" for all purposes of the Unvested Share Repurchase Option with the same force and effect as the Unvested Shares immediately prior to the Ownership Change. While the aggregate Repurchase Price shall remain the same after such Ownership Change, the Repurchase Price per Unvested Share upon exercise of the Unvested Share Repurchase Option following such Ownership Change shall be appropriately adjusted. For purposes of determining the Vested Percentage following an Ownership Change, credited service shall include (i) all service with any corporation which is a Participating Company at the time the services are rendered, whether or not such corporation is a Participating Company both before and after the event constituting the Ownership Change, and (ii) any additional service credited pursuant to paragraph 8(c). 12. Right of First Refusal. (a) Right of First Refusal. Except as provided in paragraph 12(g) below, in the event the Optionee proposes to sell, pledge, or otherwise transfer any Vested Shares (the "TRANSFER SHARES") to any person or entity, including, without limitation, any stockholder of the Participating Company Group, the Company shall have the right to repurchase the Transfer Shares under the terms and subject to the conditions set forth in this paragraph 12 (the "RIGHT OF FIRST REFUSAL"). (b) Notice of Proposed Transfer. Prior to any proposed transfer of the Transfer Shares, the Optionee shall give a written notice (the "TRANSFER NOTICE") to the Company describing fully the proposed transfer, including the number of Transfer Shares, the name and address of the proposed transferee (the "PROPOSED TRANSFEREE") and, if the transfer is voluntary, the proposed transfer price and containing such information necessary to show the bona fide nature of the proposed transfer. In the event of a bona fide gift or involuntary transfer, the proposed transfer price shall be deemed to be the fair market value of the Transfer Shares as determined by the Company in good faith. In the event the Optionee proposes to transfer any Transfer Shares to more than one (1) Proposed Transferee, the Optionee shall provide a separate Transfer Notice for the proposed transfer to each Proposed Transferee. The Transfer Notice shall be signed by both the Optionee and the Proposed Transferee and must constitute a binding commitment of the Optionee and the Proposed Transferee for the transfer of the Transfer Shares to the Proposed Transferee subject only to the Right of First Refusal. (c) Bona Fide Transfer. In the event that the Company shall determine that the information provided by the Optionee in the Transfer Notice is insufficient to establish the bona fide nature of a proposed voluntary transfer, the Company shall give the Optionee written 10 28 notice of the Optionee's failure to comply with the procedure described in this paragraph 12 and the Optionee shall have no right to transfer the Transfer Shares without first complying with the procedure described in this paragraph 12. The Optionee shall not be permitted to transfer the Transfer Shares if the proposed transfer is not bona fide. (d) Exercise of Right of First Refusal. In the event the proposed transfer is deemed to be bona fide, the Company shall have the right to purchase all, but not less than all, of the Transfer Shares (except as the Company and the Optionee otherwise agree) at the purchase price and on the terms set forth in the Transfer Notice by delivery to the Optionee of a notice of exercise of the Right of First Refusal within thirty (30) days after the date the Transfer Notice is delivered to the Company. The Company's exercise or failure to exercise the Right of First Refusal with respect to any proposed transfer described in a Transfer Notice shall not affect the Company's right to exercise the Right of First Refusal with respect to any proposed transfer described in any other Transfer Notice, whether or not such other Transfer Notice is issued by the Optionee or issued by a person other than the Optionee with respect to a proposed transfer to the same Proposed Transferee. If the Company exercises the Right of First Refusal, the Company and the Optionee shall thereupon consummate the sale of the Transfer Shares to the Company on the terms set forth in the Transfer Notice within sixty (60) days after the date the Transfer Notice is delivered to the Company (unless a longer period is offered by the Proposed Transferee); provided, however, that in the event the Transfer Notice provides for the payment for the Transfer Shares other than in cash, the Company shall have the option of paying for the Transfer Shares by the present value cash equivalent of the consideration described in the Transfer Notice as reasonably determined by the Company. For purposes of the foregoing, cancellation of any indebtedness of the Optionee to any Participating Company shall be treated as payment to the Optionee in cash to the extent of the unpaid principal and any accrued interest canceled. (e) Failure to Exercise Right of First Refusal. If the Company fails to exercise the Right of First Refusal in full within the period specified in paragraph 12(d) above, the Optionee may conclude a transfer to the Proposed Transferee of the Transfer Shares on the terms and conditions described in the Transfer Notice, provided such transfer occurs not later than ninety (90) days following delivery to the Company of the Transfer Notice. The Company shall have the right to demand further assurances from the Optionee and the Proposed Transferee (in a form satisfactory to the Company) that the transfer of the Transfer Shares was actually carried out on the terms and conditions described in the Transfer Notice. No Transfer Shares shall be transferred on the books of the Company until the Company has received such assurances, if so demanded, and has approved the proposed transfer as bona fide. Any proposed transfer on terms and conditions different from those described in the Transfer Notice, as well as any subsequent proposed transfer by the Optionee, shall again be subject to the Right of First Refusal and shall require compliance by the Optionee with the procedure described in this paragraph 12. (f) Transferees of Transfer Shares. All transferees of the Transfer Shares or any interest therein, other than the Company, shall be required as a condition of such transfer to agree in writing (in a form satisfactory to the Company) that such transferee shall receive and hold such Transfer Shares or interests subject to the provisions of this paragraph 12 providing for the Right of First Refusal with respect to any subsequent transfer. Any sale or transfer of any 11 29 shares acquired upon exercise of the Option shall be void unless the provisions of this paragraph 12 are met. (g) Transfers Not Subject to Right of First Refusal. Notwithstanding the foregoing, the Right of First Refusal shall not apply to any transfer or exchange of the shares acquired pursuant to the exercise of the Option if such transfer or exchange is in connection with an Ownership Change. If the consideration received pursuant to such transfer or exchange consists of stock of a Participating Company, such consideration shall remain subject to the Right of First Refusal unless the provisions of paragraph 12(i) below result in a termination of the Right of First Refusal. Furthermore, notwithstanding the foregoing, the Right of First Refusal shall not apply to a transfer of Transfer Shares to the Optionee's ancestors, descendants, or spouse or to a trustee solely for the benefit of the Optionee or the Optionee's ancestors, descendants, or spouse, or to a charitable institution; provided, however, that such transferee shall agree in writing (in a form satisfactory to the Company) to take the stock subject to all the terms and conditions of this paragraph 12 providing for a Right of First Refusal with respect to any subsequent transfer. (h) Assignment of Right of First Refusal. The Company shall have the right to assign the Right of First Refusal at any time, whether or not the Optionee has attempted a transfer, to one (1) or more persons as may be selected by the Company. (i) Early Termination of Right of First Refusal. The other provisions of this paragraph 12 notwithstanding, the Right of First Refusal shall terminate, and be of no further force and effect, upon (i) the occurrence of a Transfer of Control, unless the surviving, continuing, successor, or purchasing corporation or parent corporation thereof, as the case may be, assumes the Company's rights and obligations under the Plan, or (ii) the existence of a public market for the class of shares subject to the Right of First Refusal. A "public market" shall be deemed to exist if (x) such stock is listed on a national securities exchange (as that term is used in the Exchange Act), or (y) such stock is traded on the over-the-counter market and prices therefor are published daily on business days in a recognized financial journal. 13. Escrow. (a) Establishment of Escrow. To ensure that shares subject to the Unvested Share Repurchase Option, the Right of First Refusal and/or security for any promissory note will be available for repurchase, the Company may require the Optionee to deposit the certificate or certificates evidencing the shares which the Optionee purchases upon exercise of the Option with the Company or other escrow agent designated by the Company under the terms and conditions of escrow and security agreements approved by the Company. If the Company does not require such deposit as a condition of exercise of the Option, or if the Company releases the certificate or certificates from escrow prior to the lapsing of all such restrictions and/or security interest, the Company reserves the right at any time to require the Optionee to so deposit the certificate or certificates in escrow. The Company shall bear the expenses of the escrow. (b) Delivery of Shares to Optionee. As soon as practicable after the expiration of the Unvested Share Repurchase Option and the Right of First Refusal, and after full repayment 12 30 on any promissory note secured by the shares in escrow, the escrow agent shall deliver to the Optionee the shares no longer subject to such restrictions and no longer security for any promissory note. (c) Notices and Payments. In the event the shares held in escrow are subject to the Company's exercise of the Unvested Share Repurchase Option or the Right of First Refusal, the notices required to be given to the Optionee shall be given to the escrow agent and any payment required to be given to the Optionee shall be given to the escrow agent. Within thirty (30) days after payment by the Company, the escrow agent shall deliver the shares which the Company has purchased to the Company and shall deliver the payment received from the Company to the Optionee. 14. Stock Dividends Subject to Option Agreement. If, from time to time, there is any stock dividend, stock split, or other change in the character or amount of any of the outstanding stock of the corporation the stock of which is subject to the provisions of this Option Agreement, then in such event any and all new, substituted or additional securities to which the Optionee is entitled by reason of the Optionee's ownership of the shares acquired upon exercise of the Option shall be immediately subject to the Unvested Share Repurchase Option, the Right of First Refusal, and/or any security interest held by the Company with the same force and effect as the shares subject to the Unvested Share Repurchase Option, the Right of First Refusal, and such security interest immediately before such event. 15. Legends. The Company may at any time place legends referencing the Unvested Share Repurchase Option set forth in paragraph 11 above, the Right of First Refusal set forth in paragraph 12 above, and any applicable federal, state or foreign securities law restrictions on all certificates representing shares of stock subject to the provisions of this Option Agreement. The Optionee shall, at the request of the Company, promptly present to the Company any and all certificates representing shares acquired pursuant to the Option in the possession of the Optionee in order to carry out the provisions of this paragraph. Unless otherwise specified by the Company, legends placed on such certificates may include, but shall not be limited to, the following: (a) "THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, TRANSFERRED, ASSIGNED OR HYPOTHECATED UNLESS THERE IS AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT COVERING SUCH SECURITIES, THE SALE IS MADE IN ACCORDANCE WITH RULE 144 OR RULE 701 UNDER THE ACT, OR THE COMPANY RECEIVES AN OPINION OF COUNSEL FOR THE HOLDER OF THESE SECURITIES REASONABLY SATISFACTORY TO THE COMPANY, STATING THAT SUCH SALE, TRANSFER, ASSIGNMENT OR HYPOTHECATION IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT." (b) "THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO AN UNVESTED SHARE REPURCHASE OPTION IN FAVOR OF THE CORPORATION OR ITS ASSIGNEE SET FORTH IN AN AGREEMENT BETWEEN THE 13 31 CORPORATION AND THE REGISTERED HOLDER, OR SUCH HOLDER'S PREDECESSOR IN INTEREST, A COPY OF WHICH IS ON FILE AT THE PRINCIPAL OFFICE OF THIS CORPORATION." (c) "THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A RIGHT OF FIRST REFUSAL OPTION IN FAVOR OF THE CORPORATION OR ITS ASSIGNEE SET FORTH IN AN AGREEMENT BETWEEN THE CORPORATION AND THE REGISTERED HOLDER, OR SUCH HOLDER'S PREDECESSOR IN INTEREST, A COPY OF WHICH IS ON FILE AT THE PRINCIPAL OFFICE OF THIS CORPORATION." 16. Initial Public Offering. The Optionee hereby agrees that in the event of an initial public offering of stock made by the Company pursuant to an effective registration statement filed under the Securities Act, the Optionee shall not offer, sell, contract to sell, pledge, hypothecate, grant any option to purchase or make any short sale of, or otherwise dispose of any shares of stock of the Company or any rights to acquire stock of the Company for such period of time from and after the effective date of such registration statement as may be established by the underwriter for such initial public offering; provided, however, that such period of time shall not exceed two hundred seventy (270) days from the effective date of the registration statement to be filed in connection with such initial public offering. The foregoing limitation shall not apply to shares registered in the initial public offering under the Securities Act. The Optionee shall be subject to this paragraph provided and only if the officers and directors of the Company are also subject to similar arrangements. 17. Binding Effect. This Option Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective heirs, executors, administrators, successors and assigns. 18. Termination or Amendment. The Board, including any duly appointed committee of the Board, may terminate or amend the Plan and/or the Option at any time; provided, however, that no such termination or amendment may adversely affect the Option or any unexercised portion hereof without the consent of the Optionee. 19. Integrated Agreement. This Option Agreement constitutes the entire understanding and agreement of the Optionee and the Participating Company Group with respect to the subject matter contained herein, and there are no agreements, understandings, restrictions, representations, or warranties among the Optionee and the Company other than those as set forth or provided for herein. To the extent contemplated herein, the provisions of this Option Agreement shall survive any exercise of the Option and shall remain in full force and effect. 20. Applicable Law. This Option Agreement shall be governed by the laws of the State of Maryland as such laws are applied to agreements between Maryland residents entered into and to be performed entirely within the State of Maryland. 14 32 CIENA CORPORATION By: --------------------------------- Title: Vice President, Finance Chief Financial Officer The Optionee represents that the Optionee is familiar with the terms and provisions of this Option Agreement including the Unvested Share Repurchase Option set forth in paragraph 11 and the Right of First Refusal set forth in paragraph 12 and hereby accepts the Option subject to all of the terms and provisions thereof.

have no authority, discretion, or power to select the Outside Directors who
will receive Options, to set the exercise price of the Options, to determine
the number of shares of Stock to be subject to an Option or the time at which
an Option shall be granted, to establish the duration of an Option, or to alter
any other terms or conditions specified in the Plan, except in the sense of
administering the Plan subject to the provisions of the Plan.

         4.      SHARES SUBJECT TO PLAN.

                 4.1      MAXIMUM NUMBER OF SHARES ISSUABLE.  Subject to
adjustment as provided in Section 4.2, the maximum aggregate number of shares
of Stock that may be issued under the Plan shall be ONE HUNDRED FIFTY THOUSAND
(150,000) and shall consist of authorized but unissued shares or reacquired
shares of Stock or any combination thereof.  If an outstanding Option for any
reason expires or is terminated or canceled or shares of Stock acquired,
subject to repurchase, upon the exercise of an Option are repurchased by the
Company, the shares of Stock allocable to the unexercised portion of such
Option, or such repurchased shares of Stock, shall again be available for
issuance under the Plan.

                 4.2      ADJUSTMENTS FOR CHANGES IN CAPITAL STRUCTURE.  In the
event of any stock dividend, stock split, reverse stock split,
recapitalization, combination, reclassification or similar change in the
capital structure of the Company, appropriate adjustments shall be made in the
number and class of shares subject to the Plan, to the "Initial Option" and
"Annual Option" (as defined in Section 6.1), and to any outstanding Options,
and in the exercise price of any outstanding Options.  If a majority of the
shares which are of the same class as the shares that are subject to
outstanding Options are exchanged for, converted into, or otherwise become
(whether or not pursuant to an "Ownership Change Event" as defined in Section
8.1) shares of another corporation (the "New Shares"), the Board may
unilaterally amend the outstanding Options to provide that such Options are
exercisable for New Shares.  In the event of any such amendment,





                                       4
   5
the number of shares subject to, and the exercise price of, the outstanding
Options shall be adjusted in a fair and equitable manner as determined by the
Board, in its sole discretion.  Notwithstanding the foregoing, any fractional
share resulting from an adjustment pursuant to this Section 4.2 shall be
rounded down to the nearest whole number, and in no event may the exercise
price of any Option be decreased to an amount less than the par value, if any,
of the stock subject to the Option.

         5.      ELIGIBILITY AND TYPE OF OPTIONS.

                 5.1      PERSONS ELIGIBLE FOR OPTIONS.  An Option shall be
granted only to a person who, at the time of grant, is an Outside Director.

                 5.2      OPTIONS AUTHORIZED.  Options shall be nonstatutory
stock options; that is, options which are not treated as incentive stock
options within the meaning of Section 422(b) of the Code.

         6.      TERMS AND CONDITIONS OF OPTIONS.  Options shall be evidenced
by Option Agreements specifying the number of shares of Stock covered thereby,
in such form as the Board shall from time to time establish.  Option Agreements
may incorporate all or any of the terms of the Plan by reference and shall
comply with and be subject to the following terms and conditions:

                 6.1      AUTOMATIC GRANT OF OPTIONS.  Subject to execution by
an Outside Director of the appropriate Option Agreement, Options shall be
granted automatically and without further action of the Board, as follows:

                          (a)     INITIAL OPTION.  Each person who (i) is
elected an Outside Director on the Effective Date, or (ii) first becomes an
Outside Director after the Effective Date shall be granted an Option to
purchase FIFTEEN THOUSAND (15,000) shares of Stock on the Effective Date or the
date he or she first becomes an Outside Director, respectively (an "Initial
Option").  Notwithstanding anything herein to the contrary, an Initial Option
shall not be granted to a Director of the Company who previously did not
qualify as an Outside Director but subsequently becomes an Outside Director as
a result of the termination of his or her status as an Employee.

                          (b)     ANNUAL OPTION.  Effective after the Company
has a class of its securities registered under the Securities Exchange Act of
1934, as amended, each Outside Director (including any Director of the Company
who previously did not qualify as an Outside Director but who subsequently
becomes an Outside Director) shall be granted, on the date immediately
following the date of each annual meeting of the stockholders of the Company
(an "Annual Meeting") following which such person remains an Outside Director,
an Option to purchase FIVE THOUSAND (5,000) shares of Stock (an "Annual
Option").  Notwithstanding the foregoing, the number of shares that





                                       5
   6
may be purchased under an Annual Option by an Outside Director who has not
served continuously as a Director of the Company for at least twelve (12)
months as of the date immediately following the date of such Annual Meeting
shall be FIVE THOUSAND (5,000) times a fraction, the numerator of which is the
number of complete months the Outside Director has continuously served as a
Director of the Company as of the date immediately following the Annual Meeting
and the denominator of which is twelve (12).

                          (c)     RIGHT TO DECLINE OPTION.  Notwithstanding the
foregoing, any person may elect not to receive an Option by delivering written
notice of such election to the Board no later than the day prior to the date
such Option would otherwise be granted.  A person so declining an Option shall
receive no payment or other consideration in lieu of such declined Option.  A
person who has declined an Option may revoke such election by delivering
written notice of such revocation to the Board no later than the day prior to
the date such Option would be granted pursuant to Section 6.1(a) or (b), as the
case may be.

                 6.2      DISCRETION TO VARY OPTION SIZE.  Notwithstanding any
provision of the Plan to the contrary, the Board may, in its sole discretion,
increase or decrease the number of shares of Stock that would otherwise be
subject to one or more Initial Options or Annual Options to be granted pursuant
to Section 6.1 if, at the time of such exercise of discretion, (a) the
"disinterested administration" provisions contained in paragraph (c)(2)(i) of
Rule 16b-3 are no longer applicable to any employee benefit plan maintained by
a Participating Company and (b) the exercise of such discretion would not
otherwise preclude any transaction in an equity security of the Company by an
officer or Director of a Participating Company from being exempt from Section
16(b) of the Exchange Act pursuant to Rule 16b-3.

                 6.3      EXERCISE PRICE.  The exercise price per share of
Stock subject to an Option shall be the Fair Market Value of a share of Stock
on the date the Option is granted.

                 6.4      EXERCISE PERIOD.  Each Option shall terminate and
cease to be exercisable on the date ten (10) years after the date of grant of
the Option unless earlier terminated pursuant to the terms of the Plan or the
Option Agreement.

                 6.5      RIGHT TO EXERCISE OPTIONS.

                          (a)     INITIAL OPTION.  Except as otherwise provided
in the Plan or in the Option Agreement, an Initial Option shall (i) first
become exercisable on the date which is one (1) year after the date on which
the Initial Option was granted (the "Initial Option Vesting Date"); and (ii) be
exercisable on and after the Initial Option Vesting Date and prior to the
termination thereof in an amount equal to the number of shares of Stock
initially subject to the Initial Option multiplied by the Vested Ratio as set
forth below, less the number of shares previously acquired upon exercise
thereof.  The Vested Ratio described in the preceding sentence shall be

(b) ANNUAL OPTION. Each Annual Option grant shall be exercisable in full one year after the date of grant of such Annual Option. 6.6 PAYMENT OF EXERCISE PRICE. (a) FORMS OF CONSIDERATION AUTHORIZED. Except as otherwise provided below, payment of the exercise price for the number of shares of Stock being purchased pursuant to any Option shall be made (i) in cash, by check, or cash equivalent, (ii) by tender to the Company of shares of Stock owned by the Optionee having a Fair Market Value not less than the exercise price, (iii) by the assignment of the proceeds of a sale or loan with respect to some or all of the shares being acquired upon the exercise of the Option (including, without limitation, through an exercise complying with the provisions of Regulation T as promulgated from time to time by the Board of 7 8 Governors of the Federal Reserve System) (a "Cashless Exercise"), or (iv) by any combination thereof. (b) TENDER OF STOCK. Notwithstanding the foregoing, an Option may not be exercised by tender to the Company of shares of Stock to the extent such tender of Stock would constitute a violation of the provisions of any law, regulation or agreement restricting the redemption of the Company's stock. Unless otherwise provided by the Board, an Option may not be exercised by tender to the Company of shares of Stock unless such shares either have been owned by the Optionee for more than six (6) months or were not acquired, directly or indirectly, from the Company. (c) CASHLESS EXERCISE. The Company reserves, at any and all times, the right, in the Company's sole and absolute discretion, to establish, decline to approve or terminate any program or procedures for the exercise of Options by means of a Cashless Exercise. 6.7 TAX WITHHOLDING.

The Company shall have no obligation to deliver shares of Stock until the Participating Company Group's tax withholding obligations have been satisfied. 7. STANDARD FORM OF OPTION AGREEMENT. 7.1 INITIAL OPTION. Unless otherwise provided for by the Board at the time an Initial Option is granted, each Initial Option shall comply with and be subject to the terms and conditions set forth in the form of Nonstatutory Stock Option Agreement for Outside Directors (Initial Option) adopted by the Board concurrently with its adoption of the Plan and as amended from time to time. 7.2 ANNUAL OPTION. Unless otherwise provided for by the Board at the time an Annual Option is granted, each Annual Option shall comply with and be subject to the terms and conditions set forth in the form of Nonstatutory Stock Option Agreement for Outside Directors (Annual Option) adopted by the Board concurrently with its adoption of the Plan and as amended from time to time. 8 9 7.3 AUTHORITY TO VARY TERMS. Subject to the limitations set forth in Section 3.2, the Board shall have the authority from time to time to vary the terms of any of the standard forms of Option Agreement described in this Section 7 either in connection with the grant or amendment of an individual Option or in connection with the authorization of a new standard form or forms; provided, however, that the terms and conditions of any such new, revised or amended standard form or forms of Option Agreement are not inconsistent with the terms of the Plan. Such authority shall include, but not by way of limitation, the authority to grant Options which are immediately exercisable subject to the Company's right to repurchase any unvested shares of Stock acquired by the Optionee upon the exercise of an Option in the event such Optionee's Service is terminated for any reason. In no event, however, shall the Board be permitted to vary the terms of any standard form of Option Agreement if such change would cause the Plan to cease to qualify as a formula plan pursuant to Rule 16b-3 at any such time as any class of equity security of the Company is registered pursuant to Section 12 of the Exchange Act. 8. TRANSFER OF CONTROL. A "TRANSFER OF CONTROL" shall be deemed to have occurred in the event any of the following occurs with respect to the Company. (a) the direct or indirect sale or exchange by the stockholders of the Company of all or substantially all of the stock of the Company where the stockholders of the Company before such sale or exchange do not retain, directly or indirectly, at least a majority of the beneficial interest in the voting stock of the Acquiring Corporation as defined below after such sale or exchange; (b) a merger or consolidation where the stockholders of the Company before such merger or consolidation do not retain, directly or indirectly, at least a majority of the beneficial interest in the voting stock of the Acquiring Corporation as defined below after such merger or consolidation; (c) the sale, exchange, or transfer of all or substantially all of the assets of the Company (other than a sale, exchange, or transfer to one (1) or more subsidiary corporations (as defined in paragraph 1 above) of the Company); or (d) a liquidation or dissolution of the Company. Thirty (30) days prior the proposed effective date of any Transfer of Control, each Optionee under a stock option agreement outstanding for 335 days or more shall be credited, as of the proposed effective date of the Transfer of Control, and if still serving as a director of the Company on that date, with 100% of such shares, for purposes of determining the percentage of shares which shall be immediately 9 10 exercisable and/or fully vested under each such stock option agreement. Other options, except as set forth below, shall not be affected. Furthermore, in the event of a Transfer of Control, the surviving, continuing, successor, or purchasing corporation or parent corporation thereof, as the case may be (the "ACQUIRING CORPORATION"), shall either assume the Company's rights and obligations under outstanding stock option agreements or substitute options for the Acquiring Corporation's stock for such outstanding Options. In the event the Acquiring Corporation elects not to assume or substitute for such outstanding Options in connection with the Transfer of Control, any unexercisable and/or unvested shares subject to such outstanding stock option agreements shall be immediately exercisable and fully vested as of the date thirty (30) days prior to the proposed effective date of the Transfer of Control. The exercise and/or vesting of any Option that was permissible solely by reason of this paragraph 8 shall be conditioned upon the consummation of the Transfer of Control. Any Options which are neither assumed or substituted for by the Acquiring Corporation in connection with the Transfer of Control nor exercised as of the date of the Transfer of Control shall terminate and cease to be outstanding effective as of the date of the Transfer of Control. 9. NONTRANSFERABILITY OF OPTIONS. During the lifetime of the Optionee, an Option shall be exercisable only by the Optionee or the Optionee's guardian or legal representative. No Option shall be assignable or transferable by the Optionee, except by will or by the laws of descent and distribution. 10. INDEMNIFICATION. In addition to such other rights of indemnification as they may have as members of the Board or officers or employees of the Participating Company Group, members of the Board and any officers or employees of the Participating Company Group to whom authority to act for the Board is delegated shall be indemnified by the Company against all reasonable expenses, including attorneys' fees, actually and necessarily incurred in connection with the defense of any action, suit or proceeding, or in connection with any appeal therein, to which they or any of them may be a party by reason of any action taken or failure to act under or in connection with the Plan, or any right granted hereunder, and against all amounts paid by them in settlement thereof (provided such settlement is approved by independent legal counsel selected by the Company) or paid by them in satisfaction of a judgment in any such action, suit or proceeding, except in relation to matters as to which it shall be adjudged in such action, suit or proceeding that such person is liable for gross negligence, bad faith or intentional misconduct in duties; provided, however, that within sixty (60) days after the institution of such action, suit or proceeding, such person shall offer to the Company, in writing, the opportunity at its own expense to handle and defend the same. 10 11 11. TERMINATION OR AMENDMENT OF PLAN. The Board may terminate or amend the Plan at any time. However, subject to changes in the law or other legal requirements that would permit otherwise, without the approval of the Company's stockholders, there shall be (a) no increase in the total number of shares of Stock that may be issued under the Plan (except by operation of the provisions of Section 4.2), and (b) no expansion in the class of persons eligible to receive Options. Furthermore, to the extent required by Rule 16b-3, provisions of the Plan addressing eligibility to participate in the Plan and the amount, price and timing of Options shall not be amended more than once every six (6) months, other than to comport with changes in the Code, the Employee Retirement Income Security Act of 1974, as amended, or the rules thereunder. In any event, no termination or amendment of the Plan may adversely affect any then outstanding Option, or any unexercised portion thereof, without the consent of the Optionee, unless such termination or amendment is necessary to comply with any applicable law or government regulation.

In the event of any such amendment, the Number of Option Shares and the Exercise price shall be adjusted in a fair and equitable manner, as determined by the Board, in its sole discretion. Notwithstanding the foregoing, any fractional share resulting from an adjustment pursuant to this Section I shall be rounded down to the nearest whole number, and in no event may the Exercise Price be decreased to an amount less than the par value, if any, of the stock subject to the Option.

METHOD OF EXERCISE. Exercise of the Option shall be by written notice to the Company which must state the election to exercise the Option, the number of whole shares of Stock for which the Option is being exercised and such other representations and agreements as to the Optionee's investment intent with respect to such shares as may be required pursuant to the provisions of this Option Agreement.

TENDER OF STOCK. Notwithstanding the foregoing, the Option may not be exercised by tender to the Company of shares of Stock to the extent such tender of Stock would constitute a violation of the provisions of any law, regulation or agreement restricting the redemption of the Company's stock. The Option may not be exercised by tender to the Company of shares of Stock unless such shares either have been owned by the Optionee for more than six (6) months or were not acquired, directly or indirectly, from the Company. c. CASHLESS EXERCISE. A "Cashless Exercise" means the assignment in a form acceptable to the Company of the proceeds of a sale or loan with respect to some or all of the shares of Stock acquired upon the exercise of the Option pursuant to a program or procedure approved by the Company (including, without limitation, through an exercise complying with the provisions of Regulation T as promulgated from time to time by the Board of Governors of the Federal Reserve System). The Company reserves, at any and all times, the right, in the Company's sole and absolute discretion, to decline to approve or terminate any such program or procedure. 4. TAX WITHHOLDING. At the time the Option is exercised, in whole or in part, or at any time thereafter as requested by the Company, the 6 20 Optionee agrees to make adequate provision for any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Participating Company Group, if any, which arise in connection with the Option, including , without limitation, obligations arising upon (i) the exercise, in whole or in part, of the Option, (ii) the transfer, in whole or in part, of any shares acquired upon exercise of the Option or (iii) the lapsing of any restriction with respect to any shares acquired upon exercise of the Option. 5. CERTIFICATE REGISTRATION. Except in the event the Exercise Price is paid by means of a Cashless Exercise, the certificate for the shares as to which the Option is exercised shall be registered in the name of the Optionee, or, if applicable, the heirs of the Optionee. 6. RESTRICTIONS ON GRANT OF THE OPTION AND ISSUANCE OF SHARES. The grant of the Option and the issuance of shares of Stock upon exercise of the Option shall be subject to compliance with all applicable requirements of federal, state or foreign law with respect to such securities. The Option may not be exercised if the issuance of shares of Stock upon exercise would constitute a violation of any applicable federal, state or foreign securities laws or other law or regulations or the requirements of any stock exchange or market system upon which the Stock may then be listed. In addition, the Option may not be exercised unless (i) a registration statement under the Securities Act shall at the time of exercise of the Option be in effect with respect to the shares issuable upon exercise of the Option or (ii) in the opinion of legal counsel to the Company, the shares issuable upon exercise of the Option may be issued in accordance with the terms of an applicable exemption from the registration requirements of the Securities Act. THE OPTIONEE IS CAUTIONED THAT THE OPTION MAY NOT BE EXERCISED UNLESS THE FOREGOING CONDITIONS ARE SATISFIED. ACCORDINGLY, THE OPTIONEE MAY NOT BE A ABLE TO EXERCISE THE OPTION WHEN DESIRED EVEN THOUGH THE OPTION IS VESTED. The inability of the Company to obtain from any regulatory body having jurisdiction the authority, if any, deemed by the Company's legal counsel to be necessary to the lawful issuance and sale of any shares subject to the Option shall relieve the Company of any liability in respect of the failure to issue or sell such shares as to which such requisite authority shall not have been obtained. As a condition to the exercise of the Option, the Company may require the Optionee to satisfy any qualifications that may be necessary or appropriate, to evidence compliance with any applicable law or regulation and to make any representation or warranty with respect thereto as may be requested by the Company. 7. FRACTIONAL SHARES. The Company shall not be required to issue fractional shares upon the exercise of the Option. E. NONTRANSFERABILITY OF THE OPTION. The Option may be exercised during the lifetime of the Optionee only by the Optionee or the Optionee's guardian 7 21 or legal representative and may not be assigned or transferred in any manner except by will or by the laws of descent and distribution. Following the death of the Optionee, the Option, to the extent provided in Section G, may be exercised by the Optionee's legal representative or by any person empowered to do so under the deceased Optionee's will or under the then applicable laws of descent and distribution. F. TERMINATION OF THE OPTION. The Option shall terminate and may no longer be exercised on the first to occur of (a) the Option Expiration Date, (b) the last date for exercising the Option following termination of the Optionee's Service as described in Section G, or (c) a Transfer of Control to the extent provided in Section H. G. EFFECT OF TERMINATION OF SERVICE. 1. OPTION EXERCISABILITY. a. DISABILITY. If the Optionee's Service with the Participating Company Group is terminated because of the Disability of the Optionee, the Option, to the extent unexercised and exercisable on the date on which the Optionee's Service terminated, may be exercised by the Optionee (or the Optionee's guardian or legal representative) at any time prior to the expiration of twelve (12) months after the date on which the Optionee's Service terminated, but in any event no later than the Option Expiration Date. b. DEATH. If the Optionee's Service with the Participating Company Group is terminated because of the death of the Optionee, the Option, to the extent unexercised and exercisable on the date on which the Optionee's Service terminated, may be exercised by the Optionee's legal representative or other person who acquired the right to exercise the Option by reason of the Optionee's death at any time prior to the expiration of twelve (12) months after the date on which the Optionee's Service terminated, but in any event no later than the Option Expiration Date. The Optionee's Service shall be deemed to have terminated on account of death if the Optionee dies within three (3) months after the Optionee's termination of Service. c. OTHER TERMINATION OF SERVICE. If the Optionee's Service with the Participating Company Group terminates for any reason, except Disability or death, the Option, to the extent unexercised and exercisable by the Optionee on the date on which the Optionee's Service terminated, may be exercised by the Optionee within three (3) months after the date on which the Optionee's Service terminated, but in any event no later than the Option Expiration Date. 2. EXTENSION IF EXERCISE PREVENTED BY LAW. Notwithstanding the foregoing, if the exercise of the Option within the applicable time periods set forth in Section G.1 is prevented by the provisions of Section D.6, the Option shall 8 22 remain exercisable until three (3) months after the date the Optionee is notified by the Company that the Option is exercisable, but in any event no later than the Option Expiration Date. 3. EXTENSION IF OPTIONEE SUBJECT TO SECTION 16(B). Notwithstanding the foregoing, if a sale, within the applicable time periods set forth in Section G.1, of shares acquired upon the exercise of the Option would subject the Optionee to suit under Section 16(b) of the Exchange Act, the Option shall remain exercisable until the earliest to occur of (i) the tenth (10th) day following the date on which a sale of such shares by the Optionee would no longer be subject to such suit, (ii) the one hundred and ninetieth (190th) day after the Optionee's termination of Service, or (iii) the Option Expiration Date. H. TRANSFER OF CONTROL. A "TRANSFER OF CONTROL" shall be deemed to have occurred in the event any of the following occurs with respect to the Company. (a) the direct or indirect sale or exchange by the stockholders of the Company of all or substantially all of the stock of the company where the stockholders of the Company before such sale or exchange do not retain, directly or indirectly, at least a majority of the beneficial interest in the voting stock of the Acquiring Corporation as defined below after such sale or exchange; (b) a merger or consolidation where the stockholders of the Company before such merger or consolidation do not retain, directly or indirectly, at least a majority of the beneficial interest in the voting stock of the Acquiring Corporation as defined below after such member or consolidation; (c) the sale, exchange, or transfer of all or substantially all of the assets of the Company (other than a sale, exchange, or transfer to one (1) or more subsidiary corporations (as defined in paragraph A.1 above) of the Company); or (d) a liquidation or dissolution of the Company. Thirty (30) days prior the proposed effective date of any Transfer of Control, each Optionee under a stock option agreement outstanding for 335 days or more shall be credited, as of the proposed effective date of the Transfer of Control, and if still serving as a director of the Company on that date, with 100% of such shares, for purposes of determining the percentage of shares which shall be immediately exercisable and/or fully vested under each such stock option agreement. Other options, except as set forth below, shall not be affected. Furthermore, in the event of a Transfer of Control, the surviving, continuing, successor, or purchasing corporation or parent corporation thereof, as the case may be (the "ACQUIRING CORPORATION"), shall either assume the Company's rights and obligations under outstanding stock option agreements or 9 23 substitute options for the Acquiring Corporation's stock for such outstanding Options. In the event the Acquiring Corporation elects not to assume or substitute for such outstanding Options in connection with the Transfer of Control, any unexercisable and/or unvested shares subject to such outstanding stock option agreements shall be immediately exercisable and fully vested as of the date thirty (30) days prior to the proposed effective date of the Transfer of Control. The exercise and/or vesting or any Option that was permissible solely by reason of this paragraph H shall be conditioned upon the consummation of the Transfer of Control. Any Options which are neither assumed or substituted for by the Acquiring Corporation in connection with the Transfer of Control nor exercised as of the date of the Transfer of Control shall terminate and cease to be outstanding effective as of the date of the Transfer of Control. I. ADJUSTMENTS FOR CHANGES IN CAPITAL STRUCTURE. In the event of any stock dividend, stock split, reverse stock split, recapitalization, combination, reclassification, or similar change in the capital structure of the Company, appropriate adjustments shall be made in the number, Exercise Price and class of shares of stock subject to the Option. If a majority of the shares which are of the same class as the shares that are subject to the Option are exchanged for, converted into, or otherwise become (whether or not pursuant to an Ownership Change Event) shares of another corporation (the "New Shares"), the Board may unilaterally amend the Option to provide that the Option is exercisable for New Shares. In the event of any such amendment, the Number of Option Shares and the Exercise Price shall be adjusted in a fair and equitable manner, as determined by the Board, in its sole discretion. Notwithstanding the foregoing, any fractional share resulting from an adjustment pursuant to this Section I shall be rounded down to the nearest whole number, and in no event may the Exercise Price be decreased to an amount less than the par value, if any, of the stock subject to the Option. J. RIGHTS AS A STOCKHOLDER. The Optionee shall have no rights as a stockholder with respect to any shares covered by the Option until the date of the issuance of a certificate for the shares for which the Option has been exercised (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company). No adjustment shall be made for dividends, distributions or other rights for which the record date is prior to the date such certificate is issued, except as provided in Section I. K. LEGENDS. The Company may at any time place legends referencing any applicable federal, state or foreign securities law restrictions on all certificates representing shares of stock subject to the provisions of this Option Agreement. The Optionee shall, at the request of the Company, promptly present to the Company any and all certificates representing shares acquired pursuant to the Option in the possession of the Optionee in order to carry out the provisions of this Section. 10 24 L. BINDING EFFECT. Subject to the restrictions on transfer set forth herein, this Option Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective heirs, executors, administrators, successors and assigns. M. TERMINATION OR AMENDMENT. The Board may terminate or amend the Plan or the Option at any time; provided, however, that no such termination or amendment may adversely affect the Option or any unexercised portion hereof without the consent of the Optionee unless such termination or amendment is necessary to comply with any applicable law or government regulation. No amendment or addition to this Option Agreement shall be effective unless in writing. N. INTEGRATED AGREEMENT. This Option Agreement constitutes the entire understanding and agreement of the Optionee and the Participating Company Group with respect to the subject matter contained herein, and there are no agreements, understandings, restrictions, representations, or warranties among the Optionee and the Participating Company Group with respect to such subject matter other than those as set forth or provided for herein. To the extent contemplated herein, the provisions of this Option Agreement shall survive any exercise of the Option and shall remain in full force and effect. O. APPLICABLE LAW. This Option Agreement shall be governed by the laws of the State of Maryland as such laws are applied to agreements between Maryland residents entered into and to be performed entirely within the State of Maryland.

      Neither the execution nor delivery of this Agreement, nor the carrying on
      of the Company's business by the employees of the Company, nor the conduct
      of the Company's business as proposed, will, to the Company's knowledge,
      conflict with or result in a breach of the terms, conditions or provisions
      of, or constitute a default under, any contract, covenant or instrument
      under which any of such employees is now obligated. The Company does not
      believe it is or will be necessary to utilize any inventions of any of its

                                     -13-

      the applicable statute of limitations for any period. No deficiency
      assessment or proposed adjustment of federal income taxes or state or
      municipal taxes of the Company is pending and the Company has no knowledge
      of any proposed liability for any tax to be imposed. The Company has not
      elected pursuant to the Internal Revenue Code of 1986, as amended (the
      "Code"), to be treated as an S corporation or a collapsible corporation
      pursuant to Section 1362(a) or Section 341(f) of the Code, nor has it made
      any other elections pursuant to the Code (other than elections that
      related solely to methods of accounting, depreciation or amortization)
      that would have a material effect on the Company, its financial condition,
      its business as presently conducted or proposed to be conducted or any of
      its properties or material assets.

            3.13 CONTRACTS. Schedule 3.13 contains a true and complete list of
      all contracts and agreements to which the Company is a party or by which
      its property is bound. Except as set forth on Schedule 3.13 hereto, the
      Company has no employment or consulting contracts, deferred compensation
      agreements or bonus, incentive, profit-sharing, or pension plans currently
      in force and effect, or any understanding with respect to any of the
      foregoing. Schedule 3.13 hereto also lists all employment, non-competition
      and confidentiality agreements (i) between the Company and any employee or
      consultant of the Company or any other entity and (ii) to the Company's
      best knowledge between any employee of the Company and any former employer
      or person for whom such employee or consultant performed consulting or
      other services. All of the contracts listed on Schedule 3.13 and on other
      Schedules hereto are in full force and effect, and the Company, or to the
      best of the Company's knowledge any other party, is not in default under
      any of them, nor does any event or condition exist which after notice or
      lapse of time or both would constitute a material default thereunder. The
      Company has delivered to the Purchasers true, correct and complete copies
      of each contract and agreement listed on Schedule 3.13.

            3.14 LITIGATION.  No action, proceeding or governmental inquiry or
      investigation is pending or to  

   19
                                     -14-

      the best knowledge of the Company threatened against the Company or any of
      its officers, directors or employees (in their capacity as such) or any of
      the Company's properties before any court, arbitration board or tribunal
      or administrative or other governmental agency, nor is the Company aware
      that there is any basis for the foregoing. The foregoing includes, without
      limiting its generality, actions pending or known to the Company to be
      threatened involving the prior employment of any of the Company's
      employees or use by any of them in connection with the Company's business
      of any information, property or techniques allegedly proprietary to any of
      their former employers. The Company is not a party to or subject to the
      provisions of any order, writ, injunction, judgment or decree of any court
      or governmental agency or instrumentality. There is no action, suit,
      proceeding or investigation by the Company currently pending or that the
      Company intends to initiate.

            3.15 PRIVATE OFFERING. The Company agrees that neither the Company
      nor anyone acting on its behalf has offered or will offer any securities
      of the Company or any part thereof or any similar securities for issuance
      or sale to, or solicit any offer to acquire any of the same from, anyone
      so as to make the issuance and sale of the Series C Preferred not exempt
      from the registration requirements of Section 5 of the Securities Act of
      1933, as amended (the "Securities Act"). None of the shares of the
      Company's capital stock issued and outstanding has been offered or sold in
      such a manner as to make the issuance and sale of such shares not exempt
      from such registration requirements, and all such shares of capital stock
      have been offered and sold in compliance with all applicable federal and
      state securities laws.

            3.16 FULL DISCLOSURE. Neither this Agreement nor any certificates
      made or delivered in connection herewith contains any untrue statement of
      a material fact or omits to state a material fact necessary to make the
      statements herein or therein not misleading, in view of the circumstances
      in which they were made, provided, however, that the Company makes no
      representation or warranty with respect to any projections, other than
      that any such 

   20
                                     -15-

      projections were prepared in good faith and that the Company reasonably
      believes there is a reasonable basis for such projections. There is no
      material fact known to the Company relating to the business, prospects,
      condition (financial or otherwise), affairs, operations, or assets of the
      Company that has not been disclosed to the Purchasers in writing by the
      Company.

            3.17 FEES AND COMMISSIONS. The Company has not retained, or
      otherwise authorized to act, any finder, broker, agent, financial advisor
      or other intermediary (collectively "Intermediary") in connection with the
      transactions contemplated by this Agreement and the Company shall
      indemnify and hold harmless the Purchasers from liability for any
      compensation to any Intermediary retained or otherwise authorized to act
      by, or on behalf of, the Company, and the fees and expenses of defending
      against such liability or alleged liability.

            3.18 INTERESTED PARTY TRANSACTIONS. No officer, director or
      stockholder of the Company or any "affiliate" or "associate" (as these
      terms are defined in Rule 405 promulgated under the Securities Act) of any
      such person or entity or the Company has or has had, either directly or
      indirectly, (a) an interest in any person or entity which (i) furnishes or
      sells services or products which are furnished or sold or are proposed to
      be furnished or sold by the Company, or (ii) purchases from or sells or
      furnishes to the Company any goods or services, or (b) except as set forth
      on Schedule 3.13, a beneficial interest in any contract or agreement to
      which the Company is a party or by which it may be bound or affected.
      Except as set forth on Schedule 3.13 hereto, there are no existing
      material arrangements or proposed material transactions between the
      Company and any officer, director, or holder of more than 5% of the
      capital stock of the Company, or any affiliate or associate of any such
      person.

            3.19 ERISA. Except as set forth in Schedule 3.19, the Company does
      not maintain, sponsor, or contribute to any program or arrangement that is
      an "employee pension benefit plan," an "employee welfare benefit plan," or
      a 

   21
                                     -16-

      "multiemployer plan", as those terms are defined in Sections 3(2), 3(1),
      and 3(37) of the Employee Retirement Income Security Act of 1974, as
      amended. Except as listed in Schedule 3.13, the Company does not maintain
      or contribute to any material incentive or benefit arrangements for its
      employees. All incentive or benefit arrangements listed in Schedule 3.13
      are, and have heretofore been, operated in compliance, in all material
      respects, with the terms of such arrangements and with the requirements
      prescribed by any and all applicable laws.

            3.20 SECTION 83(b) ELECTIONS. Except as set forth in Schedule 3.20,
      to the best of the Company's knowledge, all elections and notices
      permitted by Section 83(b) of the Code, and any analogous provisions of
      applicable state tax laws have been timely filed by all individuals who
      have purchased shares of the Company's Common Stock other than pursuant to
      any stock option plans of the Company. The Company makes no representation
      or warranty regarding the content or accuracy of any such election or
      notice.

            3.21 COMPANY TRANSACTIONS. The Company has not engaged in the past

      corporation or corporations regarding the merger of the Company with or
      into any such corporation or corporations, (ii) with any corporation,
      partnership, association or other business entity or any individual
      regarding the sale, conveyance or disposition of all or substantially all
      of the assets of the Company or a transaction or series of related
      transactions in which more than fifty percent (50%) of the voting power of
      the Company is disposed of, or (iii) regarding any other form of
      liquidation, dissolution or winding up of the Company.

            3.22 PERMITS. The Company has all franchises, permits, licenses, and
      any similar authority necessary for the conduct of its business as now
      being conducted by it, the lack of which could materially and adversely
      affect the business, properties, prospects, or financial condition of the
      Company, and the Company believes it can 

   22
                                     -17-

      obtain, without undue burden or expense, any similar authority for the
      conduct of its business as planned to be conducted. The Company is not in
      default in any material respect under any of such franchises, permits,
      licenses, or other similar authority.

            3.23 INSURANCE.(i) The Company has in full force and effect life
      insurance upon the lives of the Key Employees in a minimum amount of

      Company has in full force and effect fire and casualty insurance policies,
      with extended coverage, sufficient in amount (subject to reasonable
      deductibles) to allow it to replace any of its properties that might be
      damaged or destroyed, (iii) the Company has in full force and effect
      liability and umbrella liability insurance policies sufficient in amount
      (subject to reasonable deductibles) to cover all reasonably foreseeable
      liability claims that may be made against the Company and the expenses
      thereof, (iv) no claims under any of such policies of insurance are

   

   23

      pending or have been denied, and (v) no notices of cancellation regarding
      any of such policies have been received by the Company.

            3.24 CERTAIN TAX-RELATED PROVISIONS. The Company has not made any
      purchase of its capital stock within the one (1) year period preceding the
      Closing Date and the Company covenants and agrees with the Purchasers that
      the Company will not within the one (1) year period following the Closing
      Date make any purchase of its capital stock that would result in the
      shares of Series C Preferred issued and sold pursuant to this Agreement
      not being treated as "qualified business stock" within the meaning of
      Subpart B, Section 13113 of the 1993 Tax Reform Act, without the prior
      written approval of the holders of at least fifty percent (50%) of the

                  (a) Neither the Company, nor, to the knowledge of the Company
      without investigation other than as set forth on Schedule 3.25, any
      operator of its past or present properties is in material violation, or
      alleged material violation, of any judgment, decree, order, law, license,
      rule or regulation pertaining to environmental matters, including without
      limitation the Resource Conservation and Recovery Act, as amended, the
      Comprehensive Environmental Response, Compensation and Liability Act of
      1980, as amended ("CERCLA"), and the Superfund Amendments and

      Laws").

                  (b) The Company has not received notice from any third party
      including without limitation any governmental authority, (i) that the

      under CERCLA with respect to a site 

   24
                                     -19-

      listed on the National Priorities List, 40 C.F.R. Part 300 Appendix B

      the Company has been used by the Company or, to the knowledge of the
      Company without investigation other than as set forth on Schedule 3.25, by
      any past or present owners or operators of its properties for the
      handling, manufacturing, processing, storage or disposal of Hazardous
      Substances in a manner that would materially violate applicable
      Environmental Laws. In the course of any activities conducted by the
      Company or, to the knowledge of the Company without investigation other
      than as set forth on Schedule 3.25, by any past or present owners or

      threatened releases of Hazardous Substances by the Company or, to the
      knowledge of the Company without investigation other than as set forth on
      Schedule 3.25, by any past or present owners or operators of its
      properties on, upon, into or from such properties of the Company, which
      releases would have a material adverse effect on the value of such
      properties, any adjacent properties or the environment. Any Hazardous
      Substances that have been generated by the Company or, to the knowledge of
      the Company without investigation other than as set forth on Schedule

      maintaining valid permits as required under applicable Environmental Laws,
      which transporters and facilities have been and are, to the best of the
      Company's knowledge, operating in compliance with such permits and
      applicable Environmental Laws.

      and to obtain any additional information, to the extent the Company has
      such information or could have acquired it without unreasonable effort or
      expense, all as necessary for the Purchaser to make an informed investment
      decision with respect to the purchase of the Shares. The foregoing,
      however, does not limit or modify the representations and 

   26
                                     -21-

      warranties of the Company in Section 3 of this Agreement or the right of
      such Purchaser to rely thereon.

            4.4 ABSENCE OF REGISTRATION. It understands that:

            (a) The Shares to be sold and issued hereunder (and the Common Stock
      to which such shares may be converted) are unregistered and may be
      required to be held indefinitely unless they are subsequently registered
      under the Securities Act, or an exemption from such registration is
      available.

      obligation to file a registration statement with the Securities and

      which such shares may be converted) unless such offer, sale, pledge,
      hypothecation or other disposition is (i) registered under the Securities
      Act, or (ii) in compliance with an opinion of counsel to the Purchaser,
      delivered to the Company and reasonably acceptable to the Company, to the
      effect that such offer, sale, pledge, hypothecation or other disposition
      thereof does not violate the Securities Act, and (b) the certificate(s)
      representing the Shares (and any Common Stock to which such shares may be
      converted) shall bear a legend stating in substance:

            THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
            SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE OFFERED, SOLD OR
            OTHERWISE

            UNDER SAID ACT OR, IN THE OPINION OF COUNSEL IN FORM AND SUBSTANCE
            SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR
            TRANSFER, PLEDGE OR HYPOTHECATION DOES NOT VIOLATE THE PROVISIONS
            THEREOF.

            Upon request of a holder of Series C Preferred, the Company shall
      remove the legend set forth above from the certificates evidencing such
      Shares, or issue to such holder new certificates therefor free of such
      legend, if with such request the Company shall have received an opinion of
      counsel selected by the holder and reasonably satisfactory to the Company,
      in form and substance reasonably satisfactory to the Company, to the
      effect that such Shares are not required by the Securities Act to continue
      to bear the legend.

      for appropriate transfer instructions to implement the provisions of

      the coming fiscal year; and

            (c) any such Investor shall be entitled to have one designee attend
      (but not to vote at) meetings of the Board of Directors (and business
      discussions immediately prior to such meetings) as an observer, provided
      that such designee shall not be entitled to be present at those portions

      year to the end of such month. Such financial statements shall be in
      reasonable detail and certified by the chief financial officer of the
      Company that such financial statements were prepared in accordance with
      GAAP (subject to (x) there being no footnotes contained therein and (y)
      changes resulting from year-end audit adjustments), applied on a basis
      consistent (except as otherwise disclosed therein and consented to by a

      consistent with that of the preceding fiscal year (except as otherwise
      approved by the Board of Directors), and present fairly and accurately the
      financial position of the Company as of their date, and that the audit by
      such accountants in connection with such financial statements has been

      however, that the Company will deliver the budget for 1996 by January 30,
      1996;

            (d) promptly upon the filing thereof, reports and statements filed
      by the Company or any of its Subsidiaries with the Commission (or any
      governmental authority succeeding to any of its functions) or with any
      securities exchange; and

            (e) with reasonable promptness, such other information and data with

      sale of the Shares in order to fund operating losses and working capital
      requirements.

            7.6 PUBLIC INFORMATION. At any time and from time to time after the
      earlier of the close of business on such date as (a) a registration
      statement filed by the Company under the Securities Act becomes effective,
      (b) the Company registers a class of securities under Section 12 of the
      Securities Exchange Act of 1934, as amended, or any federal statute or
      code which is a successor thereto 

   33
                                     -28-

      (the "Exchange Act"), or (c) the Company issues an offering circular
      meeting the requirements of Regulation A under the Securities Act, the
      Company shall undertake to make publicly available and available to the
      Holders (as hereinafter defined in Section 8), pursuant to Rule 144, such
      information as is necessary to enable the Holders to make sales of
      Registrable Stock (as hereinafter defined in Section 8) pursuant to that
      Rule. The Company shall comply with the current public information
      requirements of Rule 144 and shall furnish thereafter to any Holder, upon
      request, a written statement executed by the Company as to the steps it
      has taken to so comply.

            7.7 INSURANCE. The Company will maintain life insurance upon the
      lives of the Key Employees in a minimum amount of $1,000,000 each, with
      the proceeds payable to the Company, unless the Board of Directors
      determines that such insurance is no longer required to protect the
      interests of the Company. The Company also shall obtain and keep in effect
      so long as the Board of Directors deems advisable, term life insurance on
      the lives of such other employees as, and in the principal amounts as, the
      Board of Directors shall determine, in each case with proceeds payable to
      the Company. The Company will keep and maintain in full force and effect
      fire, casualty and umbrella liability insurance policies, with extended
      coverage, reasonably sufficient in amount to allow it to replace any of
      its properties that might be damaged or destroyed or pay reasonably
      foreseeable liabilities to which it may be subject.

            7.8 EMPLOYEE STOCK OPTIONS. From and after the date of this

      Directors, all shares of Common Stock and all options granted by the
      Company to employees, consultants, officers and non-investor directors for
      shares of Common Stock (a) shall, until an IPO (as defined in Section
      7.12), be subject to a right of first refusal in favor of the Company, (b)
      shall vest over a four-year period as follows: (i) 1/4 at the end of the
      twelfth calendar month following the commencement of such person's
      employment or other retention, and (ii) 

   34
                                     -29-

      1/48 at the end of each month for the next 36 months of such employment or
      other retention, and shall be subject to the right of the Company to
      repurchase any non-vested stock at the price paid by the employee prior to
      full vesting; provided that upon a sale of the Company (whether pursuant
      to a stock or asset transaction) or a merger of the Company with and into
      another company (unless the Company is the surviving corporation), all
      non-vested shares shall immediately become vested and (c) shall be subject
      to a restriction against transfer of non-vested stock, other than to a
      family trust. The rights of the Company in (a) and (b) hereof are
      assignable by the Company, subject to the approval of a majority of the
      Board of Directors, except that any assignment pursuant to Section 7.10(e)
      hereof shall not require Board approval.

            7.9 CONFIDENTIALITY. Any information provided pursuant to Sections
      7.1, 7.3 and 7.4 shall be used by each Investor solely in furtherance of
      its interests as an investor in the Company, and each Investor shall
      (except as otherwise required by law) maintain the confidentiality of all
      confidential information of the Company obtained under said sections,
      provided that (a) the Company makes an appropriate designation of any such
      confidential information, and (b) any other term of this Agreement to the
      contrary notwithstanding, the Company shall not be obligated to disclose
      any information under such Sections, the disclosure of which it believes
      in good faith would be detrimental to the business of the Company, except
      that nothing in this clause (b) will limit in any way the obligation of
      the Company and its officers to fully disclose the business affairs of the
      Company to the members of the Board of Directors that have entered into
      confidentiality agreements for the benefit of the Company. The term
      "confidential information" shall not include such information that (i) is
      or becomes generally available to the public other than as a result of a
      disclosure by an Investor or its agents, representatives or employees
      in violation of its obligations hereunder; (ii) is or becomes available
      to an Investor on a non-confidential basis from a source (other than the
      Company or one of its directors, officers, 
   35
                                     -30-

      agents, representatives or employees) that is not prohibited from
      disclosing such information by a legal, contractual or fiduciary
      obligation; or (iii) was known to an Investor on a non-confidential basis
      prior to its disclosure to such Investor by the Company.

            In the event that an Investor, or anyone to whom an Investor
      transmits any confidential information, becomes legally compelled to
      disclose any confidential information, such person will provide the
      Company with prompt notice so that it may seek a protective order or other
      appropriate remedy and/or waive compliance with the provisions of this
      Section 7.9. In the event that such protective order or other remedy is
      not obtained, or the Company waives compliance with the provisions of this
      Section 7.9, the Investor will furnish only that portion of the
      confidential information that it is advised by counsel is legally required
      and will exercise its reasonable efforts to obtain reliable assurance that
      confidential treatment will be accorded the confidential information.

            7.10 RIGHT OF FIRST REFUSAL. The Company hereby grants to each
      Investor the right of first refusal to purchase, pro-rata, all (or any
      part) of (x) New Securities (as defined in Section 7.10(a) below) that the
      Company may, from time to time, propose to sell and issue and (y) Employee
      Stock (as defined in Section 7.10(d) below) that the Company is entitled
      to, but shall not, repurchase from an employee. The Investor's pro rata
      share shall be the ratio of the number of Preferred Shares then held by
      the Investor as of the date of the Rights Notice (as defined in Section
      7.10(b)) or the Repurchase Notice (as defined in Section 7.10(e)), as the
      case may be, to the sum of the total number of Preferred Shares then held
      by all Investors (including for this purpose permitted transferees of the
      Investor pursuant to Section 7.10(f) hereof) as of such date. This right
      of first refusal shall be subject to the following provisions:

            (a) "New Securities" shall mean any Common Stock or preferred shares
      of any kind of the Company, whether now 

   36
                                     -31-

      or hereafter authorized, and rights, options, or warrants to purchase said
      Common Stock or preferred shares, and securities of any type whatsoever
      that are, or may become, convertible into said Common Stock or preferred
      shares; provided, however, that "New Securities" shall not include (i)
      securities issuable with respect to the Preferred Shares issued on or
      prior to the date hereof and shares of Series C Preferred issued
      hereunder; (ii) securities issuable upon exercise of warrants, options and
      rights issued prior to the date hereof and Common Stock issuable upon
      conversion of any securities issued under this clause (ii); (iii)
      securities offered to the public pursuant to a registration statement
      filed under the Securities Act; (iv) securities issued in connection with
      the acquisition of another corporation, business entity or line of
      business of another business entity by the Company by merger,
      consolidation, purchase of all or substantially all of the assets, or
      other reorganization as a result of which the Company owns not less than
      fifty-one percent (51%) of the voting power of such corporation; (v)
      shares of the Company's Common Stock or preferred shares issued in
      connection with any Recapitalization Event by the Company; (vi) securities
      authorized by the Company's Board of Directors to be issued in connection
      with the leasing or acquisition of assets by the Company or supply
      arrangements for the Company; (vii) options, warrants or rights issued
      pursuant to employee stock purchase and/or stock ownership plans that have
      been or will be adopted by the Company for Key Employees; (viii)
      securities reserved, not to exceed 2,110,000 shares of Common Stock, under
      employee stock option or purchase plans, or securities to be issued to
      consultants of the Company or in connection with an acquisition or the
      formation of a joint venture, in each case as approved by the Board of
      Directors; or (ix) securities issued pursuant to Section 18 hereof.

            (b) If the Company proposes to issue New Securities, it shall give
      the Investors written notice (the "Rights Notice") of its intention,
      describing the New Securities, the price, the general terms upon which the
      Company proposes to issue them, and the number of shares that the Investor
      has the right to purchase under 

   37
                                     -32-

      this Section 7.10. Each Investor (including for this purpose any permitted
      transferee of an Investor under Section 7.10(f) hereof) shall have
      twenty-five (25) days from delivery of the Rights Notice to agree to
      purchase (i) all or any part of its pro-rata share of such New Securities
      and (ii) all or any part of the pro-rata share of any other Investor to
      the extent that such other Investor does not elect to purchase its full
      pro-rata share, in each case for the price and upon the general terms
      specified in the Rights Notice, by giving written notice to the Company
      setting forth the quantity of New Securities to be purchased. If the
      Investors who elect to purchase their full pro-rata shares also elect to
      purchase in the aggregate more than 100% of the New Securities, such New
      Securities shall be sold to such Investors in accordance with their
      respective pro-rata shares.

            (c) If the Investors fail to exercise in full the right of first
      refusal within the period or periods specified in Section 7.10(b), the
      Company shall have one hundred twenty (120) days after delivery of the
      Rights Notice to sell the unsold New Securities at a price and upon
      general terms no more favorable to the purchasers thereof than specified
      in the Company's notice. If the Company has not sold the New Securities
      within said one hundred twenty (120) day period the Company shall not
      thereafter issue or sell any New Securities without first offering such
      securities to the Investors in the manner provided above.

            (d) "Employee Stock" shall mean any Common Stock of the Company,
      whether now or hereafter authorized, that the Company has issued or sold
      to an employee pursuant to an employee stock purchase, option or benefit
      plan, agreement or other offering or arrangement, including, without
      limitation, all shares sold by the Company to employees of the Company
      subject to agreements of restriction by the Company and all Reserved
      Shares described in Section 3.2(b).

            (e) If the Company has the right to repurchase any Employee Stock
      from any employee for any reason, 

   38
                                     -33-

      including, without limiting the generality of the foregoing, the
      termination of such employee's employment, and if it shall not repurchase
      all of the shares of such Employee Stock, it shall promptly give each
      Investor written notice (the "Repurchase Notice") of the Investor's right
      to repurchase, describing the Employee Stock, the price, the general terms
      upon which such Employee Stock is available for repurchase, and the number
      of shares that the Investor has the right to purchase under this Section
      7.10. Each Investor shall have fifteen (15) days from delivery of any such
      notice in accordance with Section 13 to agree to purchase (i) all or any
      part of its pro-rata share of such Employee Stock and (ii) all or any part
      of the pro-rata share of any other Investor (including, for this purpose,
      any assignee of an Investor's rights of first refusal under Section
      7.10(f) hereof) to the extent that such other Investor does not elect to
      purchase his full pro-rata share, in each case for the price and upon the
      general terms specified in the notice by giving written notice to the
      Company setting forth the quantity of Employee Stock to be purchased. If
      the Investors who elect to purchase their full pro-rata shares also elect
      to purchase in the aggregate more than 100% of the Employee Stock, such
      Employee Stock shall be sold to such Investors in accordance with their
      respective pro-rata shares.

            (f) The rights of first refusal described in this Section 7.10 are
      nonassignable except to an affiliate of each Investor or any of such
      Investor's beneficial owners, including without limitation partners of a
      general or limited partnership, shareholders of a corporation, and
      beneficiaries of a trust (a "Beneficial Owner"). Each Investor shall be
      entitled to apportion the rights of first refusal hereby granted among
      itself and its affiliates and Beneficial Owners in such proportions as it
      deems appropriate.

            7.11 MAINTENANCE OF EXISTENCE AND PROPERTIES, ETC.. The Company
      will, and will cause each of its Subsidiaries to (a) maintain its
      corporate existence, rights, governmental approvals and franchises
      necessary to the conduct of its business, (b) keep its properties in good

   39
                                     -34-

      repair, working order and condition, reasonable wear and tear excepted,
      (c) give appropriate notice of events of default pursuant to any
      agreements of the Company, (d) enter into transactions with "affiliates"
      or "associates" (as those terms are defined in Rule 405 promulgated under
      the Securities Act) only on fair and reasonable terms and (e) promptly pay
      and discharge, or cause to be paid and discharged, when due and payable,
      all lawful taxes, assessments and governmental charges or levies imposed
      upon the income, profits, property or business of the Company or any
      Subsidiary; provided, however, that any such tax, assessment, charge or
      levy need not be paid if the validity thereof shall at the time be
      contested in good faith by appropriate proceedings and provided further
      that, unless otherwise approved by the Board of Directors, the Company
      will pay all such taxes, assessments, charges or levies forthwith upon the
      commencement of proceedings to foreclose any lien which may have attached
      as security therefor.

            7.12 TERMINATION OF COVENANTS. The covenants set forth in Sections
      7.1 through 7.4, 7.10 and 7.11 shall terminate and be of no further force
      or effect on the consummation of the first firm commitment underwritten
      public offering of securities of the Company pursuant to a registration
      statement filed by the Company under the Securities Act (an "IPO") or with
      respect to shares of Common Stock held by an Investor that have been
      issued upon conversion of Preferred Shares pursuant to an Additional
      Automatic Conversion Event (as defined in Article Fifth, Section
      (d)(ii)(B) of the Third Restated Certificate).

      disposition may not, in the opinion of such Initiating Holders, be
      effected in the public marketplace (as opposed to a private transaction
      under the Securities Act) on equally favorable net terms to the Initiating
      Holders without registration of such shares under the Securities Act, the
      Initiating Holders may request the Company in writing to effect such
      registration, stating the number of shares of Registrable Stock to be
      disposed of by such Initiating Holders (which, in the aggregate, shall be
      not less than 20% of the then outstanding Registrable Stock) and the
      intended method of disposition. Upon receipt of such request, the Company
      will give prompt written notice thereof to all other Holders whereupon
      such other Holders shall give written notice to the Company within 20 days
      after the date of the Company's notice (the "Notice Period") if they
      propose to dispose of any shares of Registrable Stock pursuant to such
      registration, stating the number of shares of Registrable Stock to be
      disposed of by such Holder or Holders and the intended method of
      disposition.

            (b) The Key Employees may register securities for sale for their own
      account in the registration requested pursuant to this Section 8.2,
      subject to limitations on the number of shares which may be imposed by the
      underwriter as set forth in Section 8.4(d) below. At the time the Company
      shall give the notice to Holders required by Section 8.2(a), it shall also
      give the same notice to the Key Employees whereupon each Key Employee

   42

                                     -37-

      shall give written notice to the Company within the Notice Period if such
      Key Employee proposes to dispose of any shares of Common Stock held by him
      or her pursuant to such registration, stating the number of shares of
      Common Stock to be disposed of by such Key Employee and the intended
      method of disposition.

            (c) The Company will use its best efforts to effect promptly after
      the Notice Period the registration under the Securities Act of all shares
      of Subject Stock specified in the requests of the Initiating Holders, the
      requests of the other Holders and the requests of the Key Employees,
      subject, however, to the limitations set forth in Section 8.4.

            8.3 REGISTRATION PROCEDURES. Whenever the Company is required by the
      provisions of this Section 8 to use its best efforts to effect promptly
      the registration of shares of Registrable Stock, the Company will:

            (a) prepare and file with the Commission a registration statement
      with respect to such shares and use its best efforts to cause such
      registration statement to become and remain effective as provided herein;

            (b) prepare and file with the Commission such amendments and
      supplements to such registration statement and the prospectus used in
      connection therewith as may be necessary to keep such registration
      statement effective and current and to comply with the provisions of the
      Securities Act with respect to the disposition of all shares covered by
      such registration statement, including such amendments and supplements as
      may be necessary to reflect the intended method of disposition from time
      to time of the prospective seller or sellers of such shares, but for no
      longer than one hundred twenty (120) days subsequent to the effective date
      of such registration in the case of a registration statement on Form S-1
      or S-2 and for no longer than ninety (90) days in the case of a
      registration statement on Form S-3;

            (c) furnish to each prospective seller such number of copies of a
      prospectus, including a preliminary

   43
                                     -38-

      prospectus, in conformity with the requirements of the Securities Act, and
      such other documents, as such seller may reasonably request in order to
      facilitate the public sale or other disposition of the shares owned by
      such seller;

            (d) use its best efforts to register or qualify the shares covered
      by such registration statement under such other securities or blue sky or
      other applicable laws of such jurisdiction within the United States as
      each prospective seller shall reasonably request, to enable such seller to
      consummate the public sale or other disposition in such jurisdictions of
      the shares owned by such seller; provided, however, that in no event shall
      the Company be obligated to qualify to do business in any jurisdiction
      where it is not at the time so qualified or to take any action which would
      subject it to service of process in suits other than those arising out of
      the offer or sale of the Subject Stock covered by such registration
      statement in any jurisdiction where it is not at the time so subject;

            (e) furnish to each prospective seller (i) a signed counterpart,
      addressed to the prospective sellers, of an opinion of counsel for the
      Company, dated the effective date of the registration statement, covering
      substantially the same matters with respect to the registration statement
      (and the prospectus included therein) as are customarily covered (at the
      time of such registration) in opinions of issuer's counsel delivered to
      the underwriters in underwritten public offerings of securities, and (ii)
      a letter dated such date, from the independent certified public
      accountants of the Company, in form and substance as is customarily given
      by independent certified public accountants to underwriters in an
      underwritten public offering, addressed to the underwriters, if any, and
      to the Holders requesting registration of Registrable Stock;

            (f) in the event of any underwritten public offering, enter into and
      perform its obligations under an underwriting agreement, in usual and
      customary form, with the managing underwriter of such offering; each
      Holder 

   44
                                     -39-

      participating in such underwriting shall also enter into and perform its
      obligations under such an agreement;

            (g) notify each Holder of Registrable Stock covered by such
      registration statement at any time when a prospectus relating thereto is
      required to be delivered under the Securities Act of the happening of any
      event as a result of which the prospectus included in such registration
      statement, as then in effect, includes an untrue statement of a material
      fact or omits to state a material fact required to be stated therein or
      necessary to make the statements therein not misleading in the light of
      the circumstances then existing; and

            (h) apply for listing and use its best efforts to list the
      Registrable Stock being registered on any national securities exchange on
      which a class of the Company's equity securities are listed or, if the
      Company does not have a class of equity securities listed on a national
      securities exchange, apply for qualification and use its best efforts to
      qualify the Registrable Stock being registered for inclusion on the
      automated quotation system of the National Association of Securities
      Dealers, Inc. or on a national securities exchange.

            8.4 LIMITATIONS ON REQUIRED REGISTRATIONS. (a) The Company shall not
      be required to effect more than two registrations on behalf of the
      Investors pursuant to Section 8.2.

            (b) The Company shall not be required to cause a registration
      requested pursuant to Section 8.2 to become effective prior to the earlier
      of (i) December 1, 1998 and (ii) the expiration of six (6) months after
      the effective date of the first registration statement initiated by the
      Company (other than a registration effected solely to implement an
      employee benefit plan or a transaction to which Rule 145 of the Commission
      is applicable).

            (c) The Company shall not register securities for sale for its own
      account in any registration requested pursuant to Section 8.2 unless
      permitted to do so by the 

   45
                                     -40-

      written consent of Holders who hold at least 51% of the Registrable Stock
      as to which registration has been requested. The Company may not cause any
      other registration of securities for sale for its own account (other than
      a registration effected solely to implement an employee benefit plan) to
      be initiated after a registration requested pursuant to Section 8.2,
      unless such other registration becomes effective at least 120 days after
      the effective date of any registration requested pursuant to Section 8.2.

            (d) Whenever a requested registration is for an underwritten
      offering, only shares which are to be included in the underwriting may be
      included in the registration. Notwithstanding the provisions of Sections
      8.2(b) and 8.4(c), if the underwriter determines that (i) marketing
      factors require a limitation of the total number of shares to be
      underwritten or a limitation of the total number of shares of the Key
      Employees to be underwritten, or (ii) the offering price per share would
      be reduced by the inclusion of the shares of the Key Employees and/or the
      Company, then the number of shares to be included in the registration and
      underwriting shall first be allocated among all Holders who indicated to
      the Company their decision to distribute any of their Registrable Stock
      through such underwriting, in proportion, as nearly as practicable, to the
      respective numbers of shares of Registrable Stock owned by such Holders at
      the time of filing the registration statement, then to the Key Employees
      who have indicated to the Company their decision to distribute any of
      their Subject Stock through such underwriting, in proportion, as nearly as
      practicable, to the respective numbers of shares of Subject Stock owned by
      the Key Employees at the time of filing of the registration statement, and
      the remainder, if any, to the Company; provided, however, that if the
      underwriter determines that marketing factors require a limitation of the
      number of shares of the Key Employees to be underwritten or that the
      offering price per share would be reduced by the inclusion of the shares
      of the Key Employees, then the number of shares of the Key Employees that
      may be so included shall be reduced, or eliminated from registration, as
      the underwriter shall

   46
                                     -41-

      advise. No stock excluded from the underwriting by reason of the
      underwriter's marketing limitation shall be included in such registration.
      If any Holder, Key Employee or the Company disapproves of any such
      underwriting, such person may elect to withdraw therefrom by written
      notice to the Initiating Holders and the underwriter. The securities so
      withdrawn from such underwriting shall also be withdrawn from such
      registration.

            (e) The Company shall not be required to effect a registration
      pursuant to Section 8.2 unless the proposed disposition of shares of
      Subject Stock has an aggregate expected offering price (before deduction
      of underwriting discounts and expenses of sale) of not less than
      $5,000,000.

            (f) If at the time of any request to register Registrable Stock
      pursuant to Section 8.2 hereof, the Company is engaged, or has fixed plans
      to engage within 90 days of the time of the request, in a registered
      public offering as to which the Holders may include such Stock pursuant to
      Section 8.5 hereof or is engaged in any other activity which, in the good
      faith determination of the Company's Board of Directors, would be
      adversely affected by the requested registration to the material detriment
      of the Company, then the Company may at its option direct that such
      request be delayed for a period not in excess of six months from the
      effective date of such offering, or the date of commencement of such other
      material activity, as the case may be, such right to delay a request to be
      exercised by the Company not more than once while the rights set forth in
      Section 8.2 are in effect.

            (g) The registration rights granted under Section 8.2 shall
      terminate as to any Holder or permissible transferees or assignee of such
      rights if such person (i) holds one percent (1%) or less of the
      outstanding shares of Common Stock of the Company and (ii) would be
      permitted to sell all of the Subject Stock held by it pursuant to Rule
      144(k).

   47
                                     -42-

            8.5 INCIDENTAL REGISTRATION. If the Company at any time proposes to
      register any of its securities under the Securities Act (other than a
      registration effected solely to implement an employee benefit plan or a
      transaction to which Rule 145 of the Commission is applicable), it will
      each such time give prompt written notice to all Holders and to the Key
      Employees of its intention so to do. Upon the written request of a Holder
      or Holders or a Key Employee or Key Employees given within 20 days after
      receipt of any such notice (stating the number of shares of Subject Stock
      to be disposed of by such Holder or Holders or such Key Employee or Key
      Employees and the intended method of disposition), the Company will use
      its best efforts to cause all such shares of Subject Stock intended to be
      disposed of, the Holders or the Key Employees owners of which shall have
      requested registration thereof, to be registered under the Securities Act
      so as to permit the disposition (in accordance with the methods in said
      request) by such Holder or Holders or such Key Employee or Key Employees
      of the shares so registered, subject, however, to the limitations set
      forth in Section 8.6.

            8.6 LIMITATIONS ON INCIDENTAL REGISTRATION. If the registration of
      which the Company gives notice pursuant to Section 8.5 is for an
      underwritten offering, only securities that are to be included in the
      underwriting may be included in the registration. Notwithstanding any
      provision of Section 8.5, if the underwriter determines that marketing
      factors require a limitation of the number of shares to be underwritten,
      the underwriter may eliminate or reduce the number of shares of Subject
      Stock to be included in the registration and underwriting. The Company
      shall so advise all Holders and the Key Employees (except those Holders
      and Key Employees who have not indicated to the Company their decision to
      distribute any of their Subject Stock through such underwriting), and the
      number of shares of Subject Stock that may be included in the registration
      and underwriting shall be allocated among such Holders and Key Employees
      in proportion, as nearly as practicable, to the respective amounts of
      Subject Stock owned by such Holders and Key Employees at the time of
      filing the registration

   48
                                     -43-

      statement. No Subject Stock excluded from the underwriting by reason of
      the underwriter's marketing limitation shall be included in such
      registration. If any Holder or Key Employee disapproves of any such
      underwriting, such person may elect to withdraw therefrom by written
      notice to the Company and the underwriter. The Subject Stock and/or other
      securities so withdrawn from such underwriting shall also be withdrawn
      from such registration. The registration rights granted under Section 8.5
      shall terminate as to any Key Employee or Holder or permissible
      transferees or assignee of such rights if such person (a) holds one
      percent (1%) or less of the outstanding shares of Common Stock of the
      Company and (b) would be permitted to sell all of the Subject Stock held
      by him pursuant to Rule 144(k).

            8.7 DESIGNATION OF UNDERWRITER. (a) In the case of any registration
      effected pursuant to Section 8.2 or 8.8, a majority in interest of the
      requesting Holders shall have the right to designate the managing
      underwriter(s) in any underwritten offering.

            (b) In the case of any registration initiated by the Company, the
      Company shall have the right to designate the managing underwriter in any
      underwritten offering.

            8.8 FORM S-3. (a) The Company shall register its Common Stock under
      the Exchange Act as soon as legally permissible following the effective
      date of the first registration of any securities of the Company on Form
      S-1 and the Company shall thereafter file all reports and effect all
      qualifications and compliances as would permit or facilitate the sale and
      distribution of its stock on Form S-3. After the Company has qualified for
      the use of Form S-3, the Holders shall have the right to request up to six
      (6) registrations on Form S-3 (such requests shall be in writing and shall
      state the number of shares of Registrable Stock to be disposed of and the
      intended method of disposition) subject only to the following:

            (i)   The Company shall not be required to effect a registration
                  pursuant to this Section 8.8 

   49
                                     -44-

                  unless the Holder or Holders requesting registration propose
                  to dispose of shares of Registrable Stock having an aggregate
                  expected public offering price (before deduction of
                  underwriting discounts and expenses of sale) of at least
                  $500,000.

            (ii)  The Company shall not be required to effect a registration
                  pursuant to this Section 8.8 more frequently than once during
                  any twelve-month period.

      The Company shall give prompt written notice to all Holders and Key
      Employees of the receipt of a request for registration pursuant to this
      Section 8.8 and shall provide a reasonable opportunity for other Holders
      and Key Employees to participate in the registration, provided that if the
      registration is for an underwritten offering, the terms of paragraph (d)
      of Section 8.4 shall apply to all participants in such offering. Subject
      to the foregoing, the Company will use its best efforts to effect promptly
      the registration of all shares of Subject Stock on Form S-3 to the extent
      requested by the Holder or Holders thereof or by a Key Employee.

            (b) The registration rights granted under this Section 8.8 shall
      terminate as to any Holder or permissible transferees or assignee of such
      rights if such person (a) holds one percent (1%) or less of the
      outstanding shares of Common Stock of the Company and (b) would be
      permitted to sell all of the Subject Stock held by it pursuant to Rule
      144(k).

            8.9 COOPERATION BY PROSPECTIVE SELLERS. (a) Each prospective seller
      of Subject Stock, and each underwriter designated by a majority in
      interest of the requesting Holders, will furnish to the Company such
      information as the Company may reasonably require from such seller or
      underwriter in connection with the registration statement (and the
      prospectus included therein).

            (b) Failure of a prospective seller of Subject Stock to furnish the
      information and agreements described 

   50
                                     -45-

      in this Section 8.9 shall (i) with respect to registration rights under
      Section 8.2, terminate such prospective seller's registration rights, and
      (ii) with respect to registration rights under Section 8.5, terminate such
      prospective seller's registration rights with respect to the registration
      at issue. However, such failure shall not affect the obligations of the
      Company under this Section 8 to remaining sellers who furnish such
      information and agreements unless, in the reasonable opinion of counsel to
      the Company or the underwriters, such failure impairs or may impair the
      viability of the offering or the legality of the registration statement or
      the underlying offering.

            (c) The Holders and the Key Employees holding shares included in the
      registration statement will not (until further notice) effect sales
      thereof after receipt of telegraphic or written notice from the Company to
      suspend sales to permit the Company to correct or update a registration
      statement or prospectus; but the obligations of the Company with respect
      to maintaining any registration statement current and effective shall be
      extended by a period of days equal to the period such suspension is in
      effect unless (i) such extension would result in the Company's inability
      to use the financial statements in the registration statement initially
      filed pursuant to the Holder or Holders' request and (ii) such correction
      or update did not result from the Company's acts or failures to act.

            At the end of the period during which the Company is obligated to
      keep the registration statement current and effective as described in
      paragraph (b) of Section 8.3 (and any extensions thereof required by the
      preceding sentence), the Holders and the Key Employees holding shares
      included in the registration statement shall discontinue sales of shares
      pursuant to such registration statement upon receipt of notice from the
      Company of its intention to remove from registration the shares covered by
      such registration statement which remain unsold, and such Holders and Key
      Employees shall notify the Company of the number of shares registered
      which remain unsold immediately upon receipt of such notice from the
      Company.

   51
                                     -46-

            8.10 EXPENSES OF REGISTRATION. (a) All expenses incurred in
      effecting any registration pursuant to Sections 8.2 and 8.5 including,
      without limitation, all registration and filing fees, printing expenses,
      expenses of compliance with blue sky laws, fees and disbursements of
      counsel for the Company, expenses, fees and disbursements of one special
      counsel retained by the Holders and/or the Key Employees not to exceed
      $10,000, and expenses of any audits incidental to or required by any such
      registration, shall be borne by the Company, except (i) that all expenses,
      fees and disbursements of any additional counsel retained by the Holders
      and/or the Key Employees, and all underwriting discounts and commissions
      shall be borne by the Holders of and the Key Employees holding the
      securities registered pursuant to such registration, pro rata according to
      the quantity of their securities so registered; (ii) the Company shall not
      be required to pay for any expenses of any registration proceeding begun
      pursuant to Section 8.2 if the registration request is subsequently
      withdrawn at the unilateral written request, not concurred in by the
      Company, of the Holders of a majority of the Registrable Securities to be
      registered (in which case all participating Holders shall bear such
      expenses), unless the Holders of a majority of the Registrable Securities
      agree to forfeit their right to one demand registration pursuant to
      Section 8.2; provided, however, that if immediately prior to the time of
      such withdrawal, the Holders have learned of a materially adverse change
      in the condition, business or prospects of the Company from that known to
      the Holders at the time of their request, then the Holders shall not be
      required to pay any of such expenses and shall retain their rights
      pursuant to Section 8.2; and (iii) with respect to registrations
      effectuated under Section 8.2, the Company shall be required to pay
      expenses only in respect of the first two such registrations.

            (b) All expenses incurred in effecting any registration pursuant to
      Section 8.8, including without limitation all registration and filing
      fees, printing expenses, expenses of compliance with blue sky laws, fees
      and disbursements of counsel for the Company, expenses,


   52
                                     -47-

      fees and disbursements of special counsel retained by the Holders and/or
      the Key Employees, all underwriting discounts and commissions, and
      expenses of any audits incidental to or required by any such registration,
      shall be borne by the Holders of, and the Key Employees holding, the
      securities registered pursuant to such registration, pro rata according to
      the quantity of their securities so registered.

            8.11 INDEMNIFICATION. (a) To the extent permitted by law, the
      Company will indemnify and hold harmless each Holder and Key Employee
      requesting or joining in a registration, each agent, officer and director
      of such Holders, each person controlling (within the meaning of Section 15
      of the Securities Act) such Holder and each underwriter and selling broker
      of the securities so registered (collectively, "Indemnitees") against all
      claims, losses, damages and liabilities (or actions in respect thereof)
      arising out of or based on any untrue statement (or alleged untrue
      statement) of a material fact contained in any prospectus, offering
      circular or other document incident to any registration, qualification or
      compliance (or in any related registration statement, notification or the
      like) or any omission (or alleged omission) to state therein a material
      fact required to be stated therein or necessary to make the statements
      therein not misleading, or any violation (or alleged violation) by the
      Company of the Securities Act, the Exchange Act or state securities laws
      or any rule or regulation promulgated under the Securities Act, the
      Exchange Act or a state securities law, in each case applicable to the
      Company, and will reimburse each such Indemnitee for any legal and any
      other fees and expenses reasonably incurred in connection with
      investigating or defending any such claim, loss, damage, liability or
      action, provided, however, that the Company will not be liable to any
      Indemnitee in any such case to the extent that any such claim, loss,
      damage or liability is caused by any untrue statement or omission so made
      in strict conformity with written information furnished to the Company by
      an instrument duly executed by such Indemnitee and stated to be
      specifically for use therein and except that the foregoing indemnity
      agreement 
   53
                                     -48-

      is subject to the condition that, insofar as it relates to any such untrue
      statement (or alleged untrue statement) or omission (or alleged omission)
      made in the preliminary prospectus but eliminated or remedied in the
      amended prospectus on file with the Commission at the time the
      registration statement becomes effective or in the amended prospectus
      filed with the Commission pursuant to Rule 424(b) (the "Final
      Prospectus"), such indemnity agreement shall not inure to the benefit of
      any underwriter, or any Indemnitee if there is no underwriter, if a copy
      of the Final Prospectus was not furnished to the person or entity
      asserting the loss, liability, claim or damage at or prior to the time
      such furnishing is required by the Securities Act; provided, further, that
      this indemnity shall not be deemed to relieve any underwriter of any of
      its due diligence obligations; provided, further, that the indemnity
      agreement contained in this subsection 8.11(a) shall not apply to amounts
      paid in settlement of any such claim, loss, damage, liability or action if
      such settlement is effected without the consent of the Company, which
      consent shall not be unreasonably withheld.

            (b) To the extent permitted by law, each Holder and each Key
      Employee requesting or joining in a registration and each underwriter and
      selling broker of the securities so registered will indemnify and hold
      harmless the Company and its officers and directors and each person, if
      any, who controls any thereof within the meaning of Section 15 of the
      Securities Act and their respective successors against all claims, losses,
      damages and liabilities (or actions in respect thereof) arising out of or
      based on any untrue statement (or alleged untrue statement) of a material
      fact contained in any prospectus, offering circular or other document
      incident to any registration, qualification or compliance (or in any
      related registration statement, notification or the like) or any omission
      (or alleged omission) to state therein a material fact required to be
      stated therein or necessary to make the statements therein not misleading
      and will reimburse the Company and each other person indemnified pursuant
      to this paragraph (b) for any legal and any other fees and expenses
      reasonably incurred in 

   54
                                     -49-

      connection with investigating or defending any such claim, loss, damage,
      liability or action, provided, however, that this paragraph (b) shall
      apply only if (and only to the extent that) such statement or omission was
      made in reliance upon and in strict conformity with written information
      (including, without limitation, written negative responses to inquiries)
      furnished to the Company by an instrument duly executed by such Holder,
      Key Employee, underwriter or selling broker and stated to be specifically
      for use in such prospectus, offering circular or other document (or
      related registration statement, notification or the like) or any amendment
      or supplement thereto; and except that the foregoing indemnity agreement
      is subject to the condition that, insofar as it relates to any such untrue
      statement (or alleged untrue statement) or omission (or alleged omission)
      made in the preliminary prospectus but eliminated or remedied in the
      amended prospectus on file with the Commission at the time the
      registration statement becomes effective or in the Final Prospectus, such
      indemnity agreement shall not inure to the benefit of (i) the Company and
      (ii) any underwriter, Holder or Key Employee, if there is no underwriter,
      if a copy of the Final Prospectus was not furnished to the person or
      entity asserting the loss, liability, claim or damage at or prior to the
      time such furnishing is required by the Securities Act; provided, further,
      that this indemnity shall not be deemed to relieve any underwriter of any
      of its due diligence obligations; provided, further, that the indemnity
      agreement contained in this subsection 8.11(b) shall not apply to amounts
      paid in settlement of any such claim, loss, damage, liability or action if
      such settlement is effected without the consent of the Holder, Key
      Employee or underwriter, as the case may be, which consent shall not be
      unreasonably withheld; and provided, further, that the obligations of such
      Holders or Key Employees shall be limited to an amount equal to the net
      proceeds received by such Holder or Key Employee from the sale of Subject
      Stock in such offering as contemplated herein, unless such claim, loss,
      damage, liability or action resulted from such Holder's or Key Employee's
      intentional fraudulent misconduct.


   55
                                     -50-

            (c) Each party entitled to indemnification hereunder (the
      "indemnified party") shall give notice to the party required to provide
      indemnification (the "indemnifying party") promptly after such indemnified
      party has actual knowledge of any claim as to which indemnity may be
      sought, and shall permit the indemnifying party (at its expense) to assume
      the defense of any claim or any litigation resulting therefrom, provided
      that counsel for the indemnifying party, who shall conduct the defense of
      such claim or litigation, shall be reasonably satisfactory to the
      indemnified party, and the indemnified party may participate in such
      defense at such party's expense, and provided further that the omission by
      any indemnified party to give notice as provided herein shall not relieve
      the indemnifying party of its obligations under this Section 8.11 except
      to the extent that the omission results in a failure of actual notice to
      the indemnifying party and such indemnifying party is damaged as a result
      of the failure to give notice. No indemnifying party, in the defense of
      any such claim or litigation, shall consent, except with the consent of
      each indemnified party, to entry of any judgment or enter into any
      settlement which does not include as an unconditional term thereof the
      giving by the claimant or plaintiff to such indemnified party of a release
      from all liability in respect to such claim or litigation.

            (d) The reimbursement required by this Section 8.11 shall be made by
      periodic payments during the course of the investigation or defense, as
      and when bills are received or expenses incurred.

            (e) The obligation of the Company under this Section 8.11 shall
      survive the redemption, if any, of the Preferred Shares, and the
      completion of any offering of Subject Stock in a registration statement
      under this Section 8, or otherwise.

            8.12 RIGHTS THAT MAY BE GRANTED TO SUBSEQUENT INVESTORS. (a) Within
      the limitations prescribed by this paragraph (a), but not otherwise, the
      Company may grant to subsequent investors in the Company rights of

   56
                                     -51-

      incidental registration (such as those provided in Section 8.5). Such
      rights may only pertain to shares of Common Stock, including shares of
      Common Stock into which any other securities may be converted. Such rights
      may be granted with respect to (i) registrations actually requested by
      Initiating Holders pursuant to Section 8.2, but only in respect of that
      portion of any such registration as remains after inclusion of all
      Registrable Stock requested by Holders but before inclusion of any Subject
      Stock requested by the Key Employees and (ii) registrations initiated by
      the Company, but only in respect of that portion of such registration as
      remains after inclusion of all Subject Stock. With respect to
      registrations which are for underwritten public offerings, the number of
      shares held by subsequent investors that may be included in the
      underwriting shall be allocated as specified in clauses (i) and (ii) of
      the third sentence of this paragraph (a). Shares not included in such
      underwriting shall not be registered.

            (b) The Company may not grant to subsequent investors in the Company
      rights of registration upon request (such as those provided in Sections
      8.2 and 8.8) unless (i) such rights are limited to shares of Common Stock,
      (ii) all Holders and the Key Employees are given enforceable contractual
      rights to participate in registrations requested by such subsequent
      investors (but subordinate to the rights of priority of registration set
      forth in Sections 8.4(d) and 8.6), such participation to be on a pro-rata
      basis, and subject to the limitations, described in the final three
      sentences of paragraph (a) of this Section 8.12, (iii) such rights shall
      not become effective prior to 90 days after the effective date of the
      first registration pursuant to Section 8.2 and (iv) such rights shall not
      be more favorable than those granted to the Holders.

            8.13 TRANSFER OF REGISTRATION RIGHTS. The registration rights
      granted to the Investors under this Section 8 may be transferred but only
      to (i) a transferee who shall acquire not less than 500,000 shares of
      Registrable Stock, as adjusted for Recapitalization 

   57
                                     -52-

      Events, (ii) affiliates of the Investors, (iii) Beneficial Owners, and
      (iv) spouses, ancestors, lineal descendants, and siblings (and lineal
      descendants and siblings of such spouses who acquire Registrable Stock by
      gift, will or intestate succession) if all such transferees or assignees
      agree in writing to appoint a single representative as their attorney in
      fact for the purpose of receiving any notices and exercising their rights
      under this Section 8.

            8.14 "STAND-OFF" AGREEMENT. In consideration for the Company
      performing its obligations under this Section 8, each Investor and each
      Key Employee severally agrees for such period of time (not to exceed 270
      days) as is determined by the underwriters managing any underwritten
      offering of the Company's securities (the "Managing Underwriter") from the
      effective date of any registration (other than a registration effected
      solely to implement an employee benefit plan) of securities of the Company
      (upon request of the Company or of the Managing Underwriter) not to sell,
      make any short sale of, loan, grant any option for the purchase of, or
      otherwise dispose of any Subject Stock or any other stock of the Company
      held by each Investor or Key Employee, other than shares of Subject Stock
      included in the registration, without the prior written consent of the
      Company or such underwriters, as the case may be, provided that all
      officers and directors of the Company and each holder of more than 2% of
      the outstanding Common Stock shall enter into similar agreements.

            8.15 DELAY OF REGISTRATION. The Investors and the Key Employees
      shall have no right to take any action to restrain, enjoin, or otherwise
      delay any registration as the result of any controversy that might arise
      with respect to the interpretation or implementation of this Section 8.

      9. NEGATIVE COVENANTS. (a) So long as not less than 500,000 Preferred
Shares (as adjusted for Recapitalization Events) are outstanding, the Company
shall not, without the affirmative vote of the holders of record of at least 51%
of

   58
                                     -53-

the outstanding Preferred Shares, voting together as one class:

            (i) declare or pay any dividends or make any other distributions on
      shares of Common Stock;

            (ii) repurchase, or permit any corporation, firm or entity under its
      control (a "Controlled Entity") to repurchase any shares of Series C
      Preferred, Series B Preferred, Series A Preferred or Common Stock (other
      than Employee Stock or redemptions effected upon the terms contained in
      the Third Restated Certificate);

            (iii) make, or permit any Controlled Entity to make, any investments
      in, loans, advances, capital contributions, or transfers of property to
      any person or entity (other than to the Company, a wholly-owned subsidiary
      of the Company or to their respective employees in the ordinary course of
      business as advances against salary, as employee expense advances or to
      enable such employees to either purchase Employee Stock or exercise
      options for Common Stock issued to them pursuant to stock option plans by
      giving a promissory note therefor);

            (iv) create, incur, assume, guaranty or become liable for, or permit
      any Controlled Entity to create, incur, assume, guaranty or become liable
      for, any Indebtedness other than (A) current liabilities of the Company
      not incurred through the borrowing of money or the obtaining of credit
      except credit on an open account customarily extended; (B) Indebtedness in
      respect of taxes or other governmental charges not yet due and payable or
      being contested in good faith and by appropriate proceedings; (C)
      refinancings of the Indebtedness listed in Schedule 3.5 in a principal
      amount not exceeding the outstanding principal and accrued interest on
      such Indebtedness; and (D) Indebtedness incurred in the ordinary course of
      business in connection with the acquisition by the Company after the date
      hereof of any personal property of the Company, provided that the amount
      of such Indebtedness in respect of any such acquisition shall not exceed
      $3,000,000 without the 

   59
                                     -54-

      consent of at least 66-2/3% of the Board of Directors (for purposes of
      this subparagraph (a)(iv), Indebtedness shall include all obligations,
      contingent or otherwise, that in accordance with GAAP should be classified
      as liabilities on the balance sheet of the Company);

            (v) engage in any business other than the business engaged in at the
      Closing Date, or provided for in the Operating Plan, or liquidate or
      wind-up its business or its assets;

            (vi) merge with or consolidate into any corporation, firm or entity,
      or sell, lease or otherwise dispose of all or substantially all of its
      assets unless the Company is the surviving or acquiring entity;

            (vii) mortgage or pledge, or create a security interest in, or
      permit any Controlled Entity to mortgage, pledge or create a security
      interest in, all or substantially all of the property of the Company or
      such Controlled Entity, unless unanimously approved by the entire Board of
      Directors of the Company; or

            (ix) own, or permit any Controlled Entity to own, any stock or other
      securities of any Controlled Entity or other corporation, partnership or
      entity unless it is wholly owned by the Company, except certificates of
      deposit, high quality commercial paper, United States government
      securities and other short-term, high quality liquid investment grade
      securities.

            10. BOARD OF DIRECTORS. (a) The Investors and the Key Employees (in
      respect of the designations in clause (iv) below) shall act in all
      capacities and vote the shares of stock of the Company now or hereafter
      owned or controlled by them so as to cause and maintain the election to
      the Board of Directors of (i) one designee of the holders of a majority in
      interest of the Series C Preferred, voting as a single class, which
      designee shall be a designee of Weiss, Peck & Greer (the "WP&G Designee"),
      subject to the approval of the remaining directors, which approval shall
      not be unreasonably withheld, and which WP&G Designee Weiss, Peck & Greer
      may

   60
                                     -55-

      at any time and from time to time, in its sole discretion, remove; (ii)
      one designee of the holders of a majority in interest of the Series B
      Preferred, voting as a single class, which designee shall be a designee of
      Charles River Partnership VII; (iii) three designees of the holders of a
      majority in interest of the Series A Preferred, voting as a single class;
      and (iv) David Huber and Patrick Nettles. Weiss, Peck & Greer agrees to
      act with reasonable promptness to propose as a replacement of the initial
      WP&G Designee an outside director of recognized standing in the industry
      in which the Company operates, and thereafter, with respect to nominations
      of any subsequent WP&G Designees, to propose for consideration only
      candidates satisfying this same qualification criterion.

            (b) The Investors and Key Employees shall act in all capacities
      and/or vote the shares of stock of the Company now or hereafter owned or
      controlled by them so as to maintain the number of directors on the Board
      of Directors to be limited to seven members.

            (c) Each certificate for shares of capital stock of the Company
      owned by an Investor or Key Employee shall bear thereon substantially the
      following legend:

            "THE STOCK REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO THE TERMS
            OF A PREFERRED STOCK PURCHASE AGREEMENT DATED AS OF DECEMBER 20,
            1995 WITH RESPECT TO THE VOTING OF THE SHARES REPRESENTED BY THIS
            CERTIFICATE, OR ANY INTEREST THEREIN, WHICH MAY BE EXAMINED AT THE
            OFFICES OF THE COMPANY."

            (d) Until the earlier of (i) the fifth anniversary of the date of
      this Agreement and (ii) the consummation by the Company of an IPO, neither
      Key Employee shall offer, sell, transfer, assign, pledge, hypothecate or
      otherwise dispose of in the aggregate, in one or more transactions, more
      than 10% of the shares of Common Stock owned by such Key Employee at the
      date of this Agreement (and without giving effect to any of the
      transactions contemplated hereby) without the prior consent of the Board
      of Directors, provided this provision shall not 


   61
                                     -56-

      apply to any transactions exempted from the Amended and Restated Co-Sale
      Agreement of even date herewith pursuant to Section 2.05(a)(i)or (iv).

            (e) Each party shall act in all capacities to cause any transferee
      of the shares of its stock in the Company to assume the obligations of its
      or his transferor hereunder.

            (f) Any designee of any holder or holders of the Company's stock who
      shall serve as a member of the Board shall have full authority to exercise
      his discretion and business judgment to perform his duty as Director and
      shall incur no special obligation or liability to any of such holders as a
      result of such exercise. No party shall have any claim against any such
      designee, or the holder or holders who selected such designee, with regard
      to such selection. The Company shall take all actions as may be necessary
      to cause the Company to indemnify the members of the Board of Directors to
      the fullest extent permitted under applicable law.

            (g) The provisions of this Section 10 shall continue in effect until
      the earlier of (i) an Automatic Conversion Event (as defined in the Third
      Restated Certificate) or (ii) ten years from the date hereof.

      11. EXPENSES. The Company will pay (a) all the costs and expenses of the
reproduction of this Agreement, of all agreements and documents referred to
herein and of the certificates for the Shares; (b) all taxes (if any) payable

covenants contained herein or made in writing by or on behalf of the Company in

pursuant to one or more registration statements under the Securities Act or
pursuant to Rule 144 or otherwise) acting together as a single class, (iv) in
the event of any modification of Section 8, Investors holding at least 67% of
the Registrable Stock (with any shares of Preferred Shares voting as the number

and provided, further, that the Board of Directors shall be permitted to grant
to any officer of the Company registration rights that are the equivalent of the
Key Employees' registration rights and the granting of such officer registration
rights shall not be deemed a modification of the Key Employees' registration
rights, for purposes of this Section 14(a) if granted with the approval of a
majority of the Board of Directors.

      (b) Notwithstanding anything to the contrary contained in Section 14(a),
the Board of Directors of the Company may, from time to time, designate
additional employees of the Company as "Key Employees," as such term is used in
this Agreement. Each person so designated shall execute all such documents as
shall be necessary so that he or she shall be considered a "Key Employee" within
the meaning of this Agreement, and thereafter, all references to "Key Employees"
in this Agreement shall be deemed to include such designee; provided that in no
event shall a person be considered a Key Employee if such person is no longer
employed by the Company.

      15. EXCULPATION AMONG PURCHASERS. Each Purchaser acknowledges that it is
not relying upon any statements or instruments made or issued by any person,
firm or corporation, other than the Company and its officers, directors and
agents, in making its decision to invest in the Company. Each Purchaser agrees
that no other Purchaser nor the respective controlling persons, officers,
directors, partners, agents, or employees of any Purchaser shall be liable to
such Purchaser


   66
                                     -61-

for any action heretofore or hereafter taken or omitted to be taken by any of
them in connection with the Preferred Shares (and Common Stock issued upon
conversion thereof).

      16. ENTIRE AGREEMENT. This Agreement, together with the schedules and
exhibits attached hereto and made a part hereof, contains the entire agreement
between the parties with respect to the transactions contemplated hereby, and
supersedes all negotiations, agreements, representations, warranties,
commitments, whether in writing or oral, prior to the date hereof.

      17. SUCCESSORS AND ASSIGNS.

            (a) Except as otherwise expressly provided in this Agreement, all of
      the terms of this Agreement shall be binding upon and inure to the benefit
      of and be enforceable by the respective successors and transferees of the
      parties hereto, except that the rights set forth in Sections 7.1, 7.3 and
      7.4 hereof may be assigned but only

                  (i) to an assignee who shall acquire not less than 100,000
            Investor Shares or not less than 100,000 shares of Series C
            Preferred, as adjusted for Recapitalization Events; or

                           (ii) in connection with the distribution by a holder
                  of Investor Shares to a Beneficial Owner who holds at least
                  100,000 shares of Series C Investor Shares or Registrable
                  Stock or not less than 100,000 shares of Series C Preferred,
                  that has been distributed to it, as adjusted for
                  Recapitalization Events.

            (b) Any other provision of this Agreement to the contrary
      notwithstanding, but at all times subject to the provisions of Sections
      4.5(a) and (b) hereof, any of the STAR Purchasers (as defined in Schedule
      1) shall be entitled to transfer its shares and to freely assign all of
      its rights under this Agreement to any legal entity 

   67
                                     -62-

      that controls, is controlled by, or is under common control with any of
      the STAR Purchasers, or that is managed by the Manager (as defined below),
      and such shares shall remain subject to the provisions of this Agreement.
      For purposes of this Section 17(b), the "Manager" means the entity that
      makes investment decisions for any of the STAR Purchasers, or any entity
      that controls, is controlled by, or is under common control with, such
      entity. For all purposes under this Agreement, the STAR Purchasers and any
      permitted transferee of any such STAR Purchaser shall be deemed together
      to be a single purchaser. Any other provision of this Agreement to the
      contrary notwithstanding, Leeway & Co. shall be entitled to transfer its
      shares and to freely assign all of its rights under this Agreement to any
      successor trustee or nominee or successor by reorganization of a qualified
      pension trust.

      18. ENFORCEMENT. (a) Remedies at Law or in Equity. If the Company shall
default in any of its obligations under this Agreement or if any representation
or warranty made by or on behalf of the Company in this Agreement or in any
certificate, report or other instrument delivered under or pursuant to any term
hereof shall be untrue or misleading in any material respect as of the date of
this Agreement or as of the date it was made, furnished or delivered, the
Purchasers or the Investors, as appropriate, may proceed to protect and enforce
their rights by suit in equity or action at law, whether for the specific
performance of any term contained in this Agreement or the Third Restated
Certificate, injunction against the breach of any such term or in furtherance of
the exercise of any power granted in this Agreement or the Third Restated
Certificate, or to enforce any other legal or equitable right of such Investors
or to take any one or more of such actions. In the event the Purchasers or the
Investors bring such an action against the Company, the prevailing party in such
dispute shall be entitled to recover from the losing party all fees, costs and
expenses of enforcing any right or asserting any defense of such prevailing
party under or with respect to this Agreement or the Third Restated Certificate,
including without limitation such reasonable fees and expenses of attorneys and
accountants, which shall include, without limitation, all fees, costs and
expenses of appeals.

   68
                                     -63-

            (b) Remedies Cumulative; Waiver. No remedy referred to herein is
intended to be exclusive, but each shall be cumulative and in addition to any
other remedy referred to above or otherwise available to the Purchasers or the
Investors at law or in equity. No express or implied waiver by the Purchasers or
the Investors of any default shall be a waiver of any future or subsequent
default, unless otherwise specified. The failure or delay of the Purchasers or
the Investors in exercising any rights granted them hereunder shall not
constitute a waiver of any such right and any single or partial exercise of any
particular right by the Purchasers or the Investors shall not exhaust the same
or constitute a waiver of any other right provided herein.

      19. PRIOR AGREEMENTS. Sections 7 through 10, 13, and 17 through 21 of the
Series A Agreement and Sections 7 through 10, 13 and 17 through 22 of the Series
B Agreement are hereby replaced in their entirety by Sections 7 through 10, 13,
and 17 through 22 of this Agreement, respectively. Except as amended and
modified hereby, the Prior Agreements shall continue in full force and effect in
accordance with their respective terms. By execution of this Agreement, (a) the
Prior Investors and the Key Employees hereby consent to the amendment of the
Prior Agreements as contemplated herein, and (b) the Prior Investors waive the
rights of first refusal under Section 7.10 of the Prior Agreements in respect of
the issuances of Series C Preferred hereunder, such waiver to be effective on
behalf of all the Investors referred to in the Prior Agreements pursuant to
Section 14 thereof.

      20. EXECUTION AND COUNTERPARTS. This Agreement may be executed in any
number of counterparts, each of which when so executed and delivered shall be
deemed an original, and all such counterparts together shall constitute one
instrument. Each party shall receive a duplicate original of the counterpart
copy or copies executed by it and by the Company.

      21. GOVERNING LAW AND SEVERABILITY. Except for matters directly in the
purview of the General Corporation Law of the State of Delaware, this Agreement
shall be governed by and construed in accordance with the laws of the State of
New York, without regard to principles of conflicts of law. In the event any
provision of this Agreement or the application



   69
                                     -64-

of any such provision to any party shall be held by a court of competent
jurisdiction to be contrary to law, the remaining provisions of this agreement
shall remain in full force and effect.

      22. HEADINGS. The descriptive headings of the Sections hereof and the
Schedules and Exhibits hereto are inserted for convenience only and do not

(k) Notwithstanding anything to the contrary contained in this Lease, Landlord shall have no right to consent to the assignment of this Lease to a purchaser in foreclosure of any previously approved leasehold mortgage given by Tenant, or to any leasehold mortgagee or its designee in lieu of such foreclosure (l) The provisions of this Section 7.5 shall also apply to any collateral assignment by Tenant of its interest under this Lease. (m) if required by any leasehold mortgagee, and notwithstanding anything to the contrary contained herein, Tenant shall have the right to record a memorandum or other evidence of this Lease provided that it pays all taxes payable in connection with such recordation. (n) Nothing in this Lease shall be deemed to prohibit the financing by Tenant of, and the granting of a lien on, any of its personal property or any of the Initial Tenant Improvements, so long as. in the case of the Initial Tenant Improvements, the lender is not given any rights that are inconsistent with the provisions of the penultimate sentence of Section 7.2 and the provisions of this Section 7.5 are fulfilled, and, as to any personal property, the lender is not given any rights that are inconsistent with the provisions of Section 14. Subject to the above provisions, Landlord agrees to reasonably cooperate with Tenant, without any pecuniary obligation therefor, in Tenant's efforts to procure financing for the Initial Tenant Improvements and agrees to execute and deliver to Tenant the Waiver, hereinafter defined in Section 14, incorporating such modifications and additions to the form of Waiver as such lender shall request, provided the same are not materially adverse to Landlord. 8. COMPLIANCE WITH REGULATIONS: 8.1 Compliance with Governmental Regulations and Private Covenants: Tenant shall, at its sole expense, continually comply with all Federal, State, and local laws, codes, ordinances, administrative and court orders and directives, rules, and regulations and those private covenants recorded in Liber 733 at folio 726 et am.

Landlord represents that is has not, during its ownership of the Real Property, entered into any private covenants other than the CC and R's. Landlord represents that as of the - 12 - 19 CIENA Completion Date, to the best of Landlord's actual knowledge, the Premises will comply with the CC and R's and all applicable laws, including the Americans with Disabilities Act and laws relating to asbestos and asbestos containing materials. Tenant shall be entitled, at its own expense, and through its own counsel, to independently contest, appeal, oppose or otherwise defer compliance with any law imposed after the Completion Date, provided, however, that as a result of Tenant's non-compliance Landlord is not subjected to criminal or civil prosecution and the Project is not materially adversely affected thereby. Landlord shall cooperate, without pecuniary liability, with Tenant as may be reasonably required in any such contest. Landlord shall be responsible for undertaking improvements to the Premises necessary to comply with laws (the costs of which shall herein be referred to as the "Government Compliance Costs"). if such Government Compliance Costs are not capital in nature. as reasonably determined under sound accounting principles, they shall be paid for by Tenant unless the noncompliance exists on the date hereof. If such Government Compliance Costs are capital in nature, as reasonably determined under sound accounting principles (the "Capital Government Compliance Costs"), such Capital Government Compliance Costs shall be amortized over such period of time as may be reasonable under the circumstances of such particular improvements and the portion of such amortized costs, together with the interest on the unamortized balance at a fluctuating annual rate that is at all times equal to l 't2% over the prime interest rate as determined from time to time by Citibank, N.A., falling within the Lease Term shall be paid by Tenant as a part of Common Area Expenses unless the noncompliance exists on the date hereof.

At or before the end of the Lease Term, as reasonably determined by Landlord, any and all damage to the Premises or the Building, caused by the installation or removal of furniture or other property, shall be repaired by Landlord at Tenant's expense. The cost of any repairs to be made by Landlord under this Lease resulting from the fault or negligence of Tenant shall include a reasonable fee for Landlord's supervision of such repairs. (d) Upon the termination of the Lease, Tenant will leave the Premises broom swept and clean, and at least in the same good condition (reasonable wear and tear and insured casualty damage excepted) as when the Lease Term began. Tenant will remove all of its property and possessions from the Premises except to the extent provided by Section 7 above, within ninety (90) days after the termination of this Lease. 9.2 Landlord's Obligations. (a) Landlord will provide, in a high quality manner consistent with the use of the Premises as a corporate headquarters, at Tenant's cost, the Additional Services and those services described in the definition of Common Area Expenses. (b) Landlord may, but will not be obligated to, make such repairs, alterations, or improvements as it or its authorized representatives deem necessary for the safety or preservation of the Building or for any other reasonable purpose upon reasonable prior notice to Tenant (except in the case of an emergency) and in such a manner as to not unreasonably interfere with Tenant's business. Basic Rent will not abate while Landlord is exercising any of its rights under this Article. (c) Landlord agrees, at Tenant's costs, to make all necessary repairs to keep the Premises and appurtenances thereto in good order and condition within a reasonable time after it shall receive written notice from the Tenant of the need of such repairs. 9.3 Landlord's Failure to Repair.

Landlord and its agents shall have the right at all reasonable times, upon reasonable prior notice to Tenant and within the company of Tenant's representative (except in the event of an emergency), during the Term to enter the Premises for the purpose of inspecting the Building, performing maintenance and repairs or for any other reasonable purpose. Whenever practicable, Landlord shall use reasonable efforts to avoid interfering with Tenant's business and should perform all work after business hours or during business hours reasonably designated by Tenant.

Landlord may show both the interior and exterior of the Premises to prospective tenants or purchasers at any time during the Term and place "For Rent" signs on the Premises during the last four (4) months of the Term 11. SUBORDINATION. This Lease shall be subject to and subordinate at all times to the lien of any mortgage, deed of trust, or financing statement now or hereafter made on the Premises, and to all advances made or hereafter to be made. This subordination provision shall be self-operative and no further instrument of subordination shall be required. Notwithstanding the foregoing, this Lease shall not be subordinate to any future mortgage or deed of trust unless the mortgagees or beneficiary thereunder deliver to Tenant a non-disturbance agreement reasonably acceptable to the Tenant. Prior to the Commencement Date, Landlord agrees to furnish to Tenant a list identifying any mortgages or ground leases affecting the Premises. Landlord represents that, as of the date hereof, to the best of its actual knowledge, Landlord is not in default, and no condition has occurred which would constitute a default, under any mortgage affecting the Premises. 12. ATTORNMENT. Tenant shall, upon the termination of Landlord's interest in the Premises and upon request, attorn to the person or entity that holds title to the reversion of the Premises (the "Successor") and to all subsequent Successors. Tenant also will pay to the Successor all rents and other sums required to be paid by Tenants and perform all of the other covenants, agreements and terms required of Tenant under this Lease. 13. ESTOPPEL CERTIFICATE. Tenant shall, during the Term of this Lease, execute, acknowledge and deliver to Landlord, or to any entity Landlord shall designate, within ten (10) business days after written notice by Landlord pursuant to Section 25 hereof, a certified written estoppel certificate in the form reasonably required by Landlord's lender or any prospective lender or purchaser. Any statement delivered pursuant to this Article 12 may be relied upon by any mortgagee or prospective mortgagee of the Building or of Landlord's interest, or any - 15 - 22 CIENA prospective assignee of any mortgagee. If Tenant fails to deliver the statement to Landlord within ten (10) business days after Landlord's notice, Tenant shall be deemed to have acknowledged that this Lease is in full force and effect, without modification except as may be represented by Landlord and that there are no uncured defaults in Landlord's performance. Furthermore, in the event Tenant's failure to deliver the statement to Landlord within the ten (10) business day period results in (i) Landlord being placed in default by its lender under its financing for the Building or (ii) Landlord's inability to close any loan which it is negotiating, Tenant may, at Landlord's sole discretion, be deemed in default of this Lease and Landlord shall have all rights and remedies available to it under this Lease in regard to a default. If at any time during the Lease Term, Tenant's lender or a permitted assignee requires Tenant to provide it an estoppel certificate from Landlord, then within ten (10) business days after written notice from Tenant's lender or such assignee for same pursuant to Section 25 hereof, Landlord shall provide a certified written estoppel certificate addressed to said lender or such assignee, certifying as to whether to Landlord's knowledge: (i) this Lease is in full force and effect; and (ii) Tenant is not in breach of this Lease (and if Tenant is in breach, the nature of the breach). The estoppel certificate may not be relied upon by anyone other than Tenant's lender or any permitted assignee. Notwithstanding the foregoing provisions, Landlord shall not be required to provide an estoppel certificate if Landlord has already provided one to the party requesting the same in the twenty-four (24) months preceding the request for an estoppel certificate. 14. ASSIGNMENT OR SUBLETTING. Tenant is the only party that may use or occupy the Premises. No assignment of this Lease or subletting of all or any part of the Premises is permitted without the prior written consent of Landlord. The granting of such consent will not be unreasonably withheld or delayed with respect to the type of Assignment described in clauses (I) and (2) in the following subparagraph so long as the proposed assignee is no less creditworthy and as experienced in operating the business which will be operated in the Premises as is Tenant with respect to its business as of the date hereof. The foregoing restriction will include, but not be limited to, the following (all of which will be deemed to be an "Assignment"): (1) any assignment of this Lease or a subletting of the Premises; (2) any permission to a third party to use all or part of the Premises; (3) any mortgage or other encumbrance of this Lease or of the Premises except as specifically permitted pursuant to Section 7.5 above or in this Section; (4) the appointment of a receiver or trustee of any of the Tenant's property unless said appointment is vacated within ninety (90) days; and (5) any assignment or sale in bankruptcy or insolvency. An Assignment shall not include and no consent of Landlord shall be required to the sale of stock or other equity interest in Tenant. Although an Assignment includes an assignment of the Lease to any successor entity as a result of merger, consolidation or sale of all, or substantially all, of the assets of Tenant (a "Transfer") or to any subsidiary, parent or affiliated corporation or other entity of - 16 - 23 CIENA Tenant (a "Related Company") no consent of Landlord thereto shall be required provided such Related Company or the entity resulting from the Transfer (the "Successor Tenant") shall have a creditworthiness comparable to that of Tenant as of the date of the Transfer. All other provisions of this Section 14 shall, however, apply to such Transfer or Related Party transaction. Notwithstanding the foregoing, no creditworthiness test will be required if, (a) following such Related Company transaction, Tenant remains fully liable on the Lease; or (b) the Successor Tenant or the Related Company provides Landlord with additional security in form and substance reasonably acceptable to Landlord (not in any event to exceed, in the aggregate, an amount equal to nine (9) months of Basic Rent). Even if Landlord consents to an Assignment, Tenant will remain primarily liable under this Lease. Also, Tenant will bear all reasonable legal costs actually incurred by Landlord in connection with Landlord's review of documents concerning an Assignment, whether or not Landlord consents to it. Landlord's consent to a specific Assignment does not waive Landlord's right to withhold consent to any future or additional Assignment. Tenant will give Landlord notice of its intention to make an t Assignment at least fifteen (15) days prior to such Assignment, which notice will contain such details as Landlord may reasonably request (the "Details"). If Tenant intends to Assign this Lease, Landlord may terminate this Lease by giving written notice to Tenant within thirty (30) days after Landlord has received written notice from Tenant of an intended Assignment and Tenant has provided all requested Details. If the amount of rent and other sums received by Tenant in the nature of rent under any Assignment other than to a Related Company is more than the Rent due from Tenant under this Lease, then, after reimbursing Tenant for amounts paid toward Tenant Improvements, and other Tenant improvements to the Premises, reasonable brokerage and legal fees, transfer taxes, if any, or other tenant concessions or incentives (which reimbursement will be amortized over the Lease Term), Tenant will pay the remaining excess to Landlord on a monthly basis and promptly upon Tenant's receipt of such excess amounts. The foregoing shall not apply to transactions which do not require Landlord's consent under the foregoing provision of this Article 14. If, without Landlord's consent, this Lease is Assigned, or if the Premises are occupied or used by any party other than Tenant, a Related Company, or an entity resulting from a Transfer, then and payable by Tenant upon receipt of an invoice. If Tenant defaults, Landlord may collect rent from the assignee, subtenant, occupant or user (the "Assignee") of the Premises and apply it towards the Rent due under this Lease. Such collection will not be deemed an acceptance of the Assignee as tenant, will not waive or prejudice Landlord's right to initiate legal action against Tenant to enforce Tenant's fulfillment of its obligations under this Lease and will not release Tenant from such obligations. No assigning of this Lease or subletting of the Premises shall release or be deemed - 17 - 24 CIENA to release the assignor or sublessor from liability under this Lease for the defaults of any successor assignee (immediate or remote) or any subtenant. Notwithstanding anything contained herein to the contrary, Tenant shall have the right to grant to a lender a security interest in any of Tenant's personal property, trade fixtures, furniture, equipment and capital improvements to the extent same are personalty ("FF&E") located in the Premises. In the event that Tenant elects to so encumber such FF&E, Landlord shall, within twenty (20) days after (a) Tenant's request for a Waiver and (b) the date Tenant provides all details with respect to Tenant's proposed financing as reasonably requested by Landlord, execute and deliver a waiver of "landlord's" or other statutory or common law liens of Landlord securing payment of rent or performance of any other of Tenant's covenants under this Lease ("Waiver"). Such Waiver shall be in substantially the form attached hereto as Exhibit H. and, if required by the terms of any existing financing liens on the Real Property, shall otherwise be acceptable to the entities secured thereby. Such Waiver shall include such other terms as may be reasonably requested by the proposed FF&E lender. 15. QUIET ENJOYMENT. Upon payment of Basic Rent and Additional Rent and performance by Tenant of all covenants on Tenant's part to perform under this Lease within any applicable cure period, Tenant shall have and hold the Premises, free from any interference from Landlord and any person lawfully claiming through or under Landlord except as may be otherwise provided. 16. ALTERATIONS OR CHANGES. 16.1 Tenant shall not make any alterations, improvements, or changes (collectively the "Changes") of any kind to the Premises without securing the prior written consent of the Landlord, which consent shall not be unreasonably withheld or delayed as long as the Changes are not unlawful or would not materially reduce the value or utility of the Premises, in Landlord's reasonable opinion, and which consent shall be evidenced by a separate agreement between Landlord and Tenant setting forth the terms and conditions of making such Changes, and the terms of payment therefor. All Changes shall be completed in a prompt and workmanlike manner and shall not materially alter the character or use of the Building. Notwithstanding anything to the contrary set forth above, Tenant shall have the right to make interior non-structural Changes to the Premises so long as the Changes do not diminish the value of the Premises and so long as Landlord is given prior notice of the Changes Tenant intends to make. 16.2 Landlord shall construct the Shell Space at Tenant's sole cost and expense, in accordance with plans and specifications submitted by Tenant for Landlord's consent, which consent shall not be unreasonably withheld or delayed and shall not be withheld if said plans and specifications are substantially similar to the Schematic Floor Plans and Construction Outline Specifications regarding the initial Tenant improvements. Landlord shall seek bids for such work - 18 - 25 CIENA from competing contractors, and the bids selected shall be the ones reasonably acceptable to Landlord and Tenant. No construction of the Shell Space shall commence until Tenant and Landlord have agreed to the costs thereof. Upon completion of same by Landlord, Landlord shall represent, to the best of Landlord's actual knowledge. that the Shell Space complies with all applicable laws, including the Americans with Disabilities Act. 17. RESTORATION. 17.1 Premises Rendered Partially Untenantable: If, during the Term, (i) the Building is damaged or destroyed by fire, storm, or other casualty, or (ii) a portion of the Building is ordered by a duly constituted public authority to be demolished, razed or altered due to deterioration or unsafe condition (collectively the "Listed Causes") but in either event not to the extent that Tenant, in its reasonable determination, is prevented from carrying on its business in the Premises, Landlord shall promptly restore the Premises to the condition existing immediately prior to the casualty. If the damage renders a material portion of the Premises unusable by Tenant, or if access to the Premises is materially impaired, the Basic Rent and Additional Rent shall be apportioned from and reduced during the period of unusability by the same percentage by which the unusable area bears to the Premises. Notwithstanding anything to the contrary contained in this Subsection 17.1, if during the last ten months of the Lease Term, fifty percent (50%) or more of the Premises is destroyed, whether covered by insurance or not, either party may elect to cancel and terminate this Lease by giving written notice of its election to the other party within thirty (30) days after the date of such destruction. However, regardless of any such notice of termination from Landlord to Tenant, this Lease shall not be so terminated if Tenant exercises its renewal option hereunder by written notice to Landlord within five (5) business days after Landlord's notice to terminate and in any event within the time set forth in Rider No. 1. In such event, this Lease shall remain in full force and effect and Landlord shall proceed with repair and restoration of the Premises to the extent prescribed herein. 17.2 Premises Rendered Wholly Untenantable: If, during the Term, the Building is destroyed or so damaged by any of the Listed Causes to such an extent that Tenant, in Tenant's reasonable determination, is prevented from carrying on its business in the Premises (a "total destruction"), Landlord shall restore the Premises. Notwithstanding the aforesaid, if Landlord is not able to use insurance proceeds for such restoration and the reasonably estimated cost of restoration exceeds $2,000,000.00, Landlord may terminate the Lease. Landlord shall exercise this option by giving written notice to Tenant within thirty (30) days after the casualty. In the event of termination, Tenant shall be required to surrender the Premises as soon as possible and Basic Rent and Additional Rent shall abate from and be apportioned to the date of the casualty. If the Landlord restores the Premises, the restoration shall be completed as promptly as reasonably possible, and the Basic Rent and Additional Rent shall be apportioned from and abate during the - 19 - 26 CIENA period of restoration until the date when Tenant is able to make reasonable use of the Premises. Notwithstanding the provisions of this Subsection 17.2, within sixty (60) days after the date of total destruction of the Premises, Landlord shall obtain from Landlord's architect or contractor an estimate of the time which will be required to repair the Premises. Landlord shall promptly communicate said estimate to Tenant. In the event that said estimate of time exceeds One hundred eighty (180) days (provided Landlord is able to provide reasonably satisfactory alternate premises to Tenant in Howard County or Anne Arundel County, Maryland within a fifteen (15) mile radius of the Premises and at no greater rent than Tenant is then paying hereunder) or ninety (90) days (if no alternate space can be provided) from the date of such destruction, then Tenant shall have the right, within ten (10) days after receipt of said estimate, to terminate this Lease without any further liability or obligation on the part of the parties hereto for obligations thereafter accruing, provided that Tenant shall give written notice to Landlord within said ten (10) days and that no Event of Default exists hereunder. 17.3 Notwithstanding subsections 17.1 and 17.2, but subject to Section 19.4, if the partial or total damage or destruction is due to the fault, negligence, or other willful misconduct of Tenant, its agents, employees or visitors, the damage shall be repaired by Landlord at Tenant's expense except in such cases as Landlord, in its sole discretion, shall decide not to repair or rebuild the Building or the Premises and there shall be no apportionment or abatement of Rent. 17.4 No liability shall accrue to Landlord for delay in commencing or completing any repairs or restoration to either the Premises or the Building caused by adjustment of insurance claims governmental requirements or any cause beyond Landlord's reasonable control. Nothing in this Section 17.4 shall affect the termination and abatement rights hereinabove provided. 17.5 No termination, pursuant to this Article 17, shall release Tenant from any liability to Landlord or from any of the obligations or duties imposed on Tenant prior to any termination. - 20 - 27 CIENA 18. CONDEMNATION. 18.1 If during the Term, all or a substantial part of (i) the Premises, (ii) the means of ingress and egress thereto, or (iii) the means of obtaining services or utilities to which Tenant is entitled is taken by eminent domain, this Lease shall terminate as of the date of taking, and the Basic Rent and Additional Rent shall be apportioned to and abate from that date. Tenant shall have no right to participate in any award or damages for any such taking and hereby assigns all of its right, title and interest therein to Landlord. For purposes of this Article, "a substantial part of the Premises" shall mean so much of the Premises as to render the remainder inadequate and not practicably capable of repair so as to permit Tenant to carry on its business to substantially the same extent and with substantially the same efficiency as before the taking. 18.2 if, during the Term, less than "a substantial part of the Premises" or the means of ingress and egress thereto is taken by eminent domain, this Lease shall remain in full force and effect and Tenant shall have no right to participate in any award or damages for the taking. Landlord shall, at its expense, up to but not in excess of the amount of the award of damages received, promptly make all necessary repairs and improvements needed to make the remainder of the Premises adequate to permit Tenant to carry on its business to substantially the same extent and the same efficiency as before the taking. If, as a result of any taking, a part of the Building is rendered permanently or temporarily unusable, the Basic Rent and Additional Rent shall be reduced by a fair and reasonable amount, not, however, to exceed the proportion by which the portion of the Premises taken or made unusable bears to the entire Premises. If the unusability is temporary, the rental abatement shall be apportioned from the date of taking to the date when full usability is restored. If the taking does not render any part of the Premises unusable, there shall be no abatement of Basic Rent and Additional Rent. 18.3 For the purpose of this Article, "taking under the power of eminent domain" shall include a negotiated sale or lease and transfer of possession to a condemning authority under bona fide threat of condemnation for public use. Landlord alone shall have the right to negotiate with the condemning authority and conduct and settle all litigation connected with the condemnation. As used in this Article. the words "award or damages" shall, in the event of such sale or settlement, include the purchase or settlement price. 18.4 Nothing shall, however, prevent Tenant from separately claiming and receiving from the condemning authority compensation for the taking of Tenant's own tangible property or the unamortized cost of the Capital Improvements, and damages for Tenant's loss of business, business interruption, goodwill or removal and relocation. 19. INSURANCE. 19.1 Tenant's Insurance responsibilities: Tenant shall, at its expense throughout the - 21 - 28 CIENA Term, maintain in force public liability insurance insuring against claims for bodily injury, including death, and property damage occurring in or about the Premises and on or about the adjoining driveways and passageways, with a combined single limit of not less than One Million Dollars ($1,000.000.00) per occurrence and Two Million Dollars ($2,000,000.00) with respect to the aggregate. (a) All required insurance shall be effected with an insurer licensed to do business in the State of Maryland, and all policies shall name Landlord and Managing Agent as additional insureds and Tenant as the insured, as their respective interests may appear. Each of these policies shall provide that notwithstanding any act or negligence of Tenant which might otherwise result in its forfeiture, the policy shall not be canceled without at least fifteen (15) days written notice to each additional insured. (b) Prior to Tenant's entering the Premises for the purposes described in Section 7.3, and thereafter not less than thirty (30) days prior to the expiration dates of expiring policies, the originals or certificates of each policy and endorsement shall be delivered to Landlord, together with satisfactory proof of the payment of the premiums. (c) Landlord has no insurable interest in Tenant's personal property and, therefore, Tenant shall be solely responsible for maintenance of any and all casualty insurance protection for such personalty. 19.2 Landlord's Insurance Responsibilities.

No termination of this Lease, taking or recovering possession of the Premises, nor acceptance of any Monthly Installment of Basic Rent or Additional Rent by Landlord with knowledge of the breach of any covenant or condition, shall act as a waiver of the breach or deprive Landlord of any remedies or actions against Tenant for Basic Rent or Additional Rent, for charges, or for damages for the breach of any covenant or condition, nor shall the bringing of any action for Basic Rent or Additional Rent, charges or damages for breach, be construed as a waiver or release of the right to insist upon the forfeiture and to obtain possession of the Premises. - 26 - 33 CIENA 20.6 Tenant shall be considered in "Habitual Default" of this Lease upon Tenant's failure, on three or more occasions during any lease year, to pay, when due following any applicable notice or cure period, any Monthly Installment of Basic Rent, Additional Rent or any other sum required by the terms of this Lease.

WAIVER OF BREACH. The failure of either party to insist upon a strict performance of any of the Lease terms, conditions, or covenants shall neither be deemed a waiver of any rights or remedies that such party may have nor be deemed a waiver of any subsequent breach or default. This instrument may not be changed, modified, or discharged orally. 25. NOTICE.

may reasonably request.

         7.4     The party asserting that an event of force majeure has
occurred shall be excused, on a day-to-day basis, from the performance of its
obligations under this Agreement to the extent prevented or delayed by such
event (and the other party likewise shall be excused, on a day-to-day basis,
from the performance of its obligations under this Agreement to the extent such
party's obligations related to the obligations are so prevented or delayed);
provided, however, that the party asserting the occurrence of a force majeure
event shall use its best efforts to avoid or remove such force majeure event.

         7.5     In the event that Supplier delays in performing or fails to
perform any of its obligations under this Agreement as a result of an event of
force majeure and such delay or failure continues for         *            or
more, Sprint shall be entitled in its sole discretion to terminate any affected
Purchase Order without penalty.  As soon as possible after the cessation of any
event of force majeure, the party which asserted such event shall give the

ARTICLE 19.  PATENT, COPYRIGHT AND TRADE SECRET

         19.1     Supplier agrees to indemnify, defend and hold harmless
Sprint, and each director, officer, employee or agent of Sprint (the
"Indemnified Parties"), against any claims, suits, proceedings, damages,
liabilities, judgments, amounts paid in settlement with the consent of the
Supplier (which consent shall not be unreasonably withheld), costs or expenses
(including the reasonable cost of investigating and defending any of the
foregoing and attorneys' fees incurred in connection therewith), joint or
several, as incurred, which may be based in whole or in part upon, or arise in
whole or in part out of (A) any infringement or alleged infringement of any
patent or copyright or similar rights protected under the laws of the United
States of America ("USA") or any other country which is a signatory to the
Paris Convention of March 20, 1883, as revised relating to the Deliverables or
use thereof;(B) any wrongful use or misappropriation or alleged wrongful use or
misappropriation of any trade secret or other proprietary rights relating to
Deliverables, hereunder pursuant to any statute, regulation or common law of
the USA or any other country which is a signatory to the Paris Convention of
March 20, 1883, as revised (collectively referred to hereinafter as
"Indemnified Liabilities"), provided that Supplier shall not be liable with
respect to any Indemnified Liabilities which result from use by Sprint of the
Equipment and Licensed Software different from the uses contemplated by this
Agreement.

         19.2     Without limiting the foregoing, in the event any such claim,
action, suit, proceeding or investigation is brought against any Indemnified
Party, unless Supplier assumes the defense as hereinafter provided, (a) the
Indemnified Parties may retain counsel satisfactory to them and Supplier and
Supplier shall pay all fees and expenses of such counsel for the Indemnified
Parties promptly as statements therefor are received; and (b) Supplier will use
all reasonable efforts to assist in the vigorous defense of any such matter,
provided that Supplier shall not be liable for any settlement effected without
its written consent, which consent, however, shall not be unreasonably
withheld.  The Supplier will be entitled to participate at its own expense in
the defense, or, if the Supplier so elects, to assume the defense of any suit
brought to enforce any such liability, but, if the Supplier elects to assume
the defense, such defense shall be conducted by counsel chosen by the Supplier.
In the event Supplier elects to assume the defense of any such suit and retain
such counsel, any Indemnified Party may retain additional counsel but shall
bear the fees and expenses of such counsel unless (i) the Supplier shall have
specifically authorized the retaining of such counsel or (ii) the parties to
such suit include such Indemnified Party, and the Supplier and the Indemnified
Party have been advised by counsel that one or more legal defenses may be
available to it or them which may not be available to the Supplier, in which
case the Supplier shall not be entitled to assume the defense of such suit
notwithstanding its obligation to bear the fees and expenses of such counsel.

         19.3     Any Indemnified Party wishing to claim indemnification under
this Article 19, upon learning of any such claim, action, suit, proceeding or
investigation, shall notify the Supplier promptly (but the failure so to notify
shall not relieve Supplier from any liability which it may have under this
Article 19 except to the extent such failure prejudices Supplier).  Supplier
shall promptly notify Sprint that it has assumed the defense of any claim,
action, suit, proceeding, or investigation and shall apprise Sprint of the
progress of such defense.

         19.4     If Sprint is enjoined from use of the Equipment or any
component thereof or Licensed Software, Supplier must procure the rights, at
Supplier's cost and expense, for Sprint to continue use of the Equipment or
affected
   27

component, or Licensed Software, or replace it with non-infringing Equipment or
components, or Licensed Software, or modify same to be non-infringing.

         19.5     This indemnity obligation shall be in addition to, and not in
limitation of, any liability or obligation which Supplier might otherwise have
to any Indemnified Party.

         19.6      The indemnities provided in this Article 19 do not extend
to: (i) any suit or proceeding which is based on an infringement claim covering
a combination of a Deliverable purchased under this Agreement with other
devices or elements not provided, and of which Supplier is unaware, or
specified by Supplier unless such is an intended combination; (ii) any
Deliverable whose infringement is a direct result of Supplier being required to
adhere to a specific design provided by Sprint if, and only if, Supplier
informs Sprint that it does not approve the specific design be; or (iii) any
Deliverable that is otherwise modified by Sprint in a manner not authorized by
Supplier.

         19.7    Except for the indemnity provisions of this Agreement, neither
party will be liable to the other for special, indirect, or consequential loss
or damage, whether or not such loss or damage is caused by the fault or
negligence of that party, its employees, agents, or subcontractors.

         19.8    No limitation of liability contained in this Agreement will be
applicable in the event of Supplier's gross negligence or intentional
misconduct, or in the event of personal injury or property damage. Furthermore,
no limitation of liability contained in this Agreement will apply with respect
to any Supplier liability arising under or relating to  Section 13.5 and 13.9,
or this Article 19.

ARTICLE 20. TERMINATION

subsequent performance by the parties before resorting to other remedies
available to them.  Any such dispute shall be referred to appropriate
executives of each party who shall have the authority to resolve the matter.
If the executives are unable to resolve the dispute, the parties may by
agreement refer the matter to an appropriate form of alternative dispute
resolution such as mediation.  If the parties cannot resolve the matter or if
they cannot agree upon an alternative form of dispute resolution, then either
party may pursue resolution of the matter through arbitration in accordance
with the rules of the American Arbitration Association applying the substantive
law of the State of Kansas without regard to any conflict of laws provisions.
The arbitration will be governed by the United States Arbitration Act, 9,
U.S.C. Section 1, et. seq. and judgment upon the award rendered by the
arbitrators may be entered by any court with jurisdiction.  The arbitrators are
not empowered to award damages in excess of compensatory damages , and each
party waives any damages in excess of compensatory damages.  The parties agree
to continue performance during the pendency of any dispute, unless performance
is terminated according to Article 20 of this Agreement.

         21.2    Notwithstanding the foregoing, either party may bring a claim
for injunctive relief as provided in Section 15.5 in any court of competent

and/or Software described above, each of the following conditions must be met
unless otherwise indicated in the P&P Attachment applicable to the Product

                          (iii)   The Product and/or Software defect was not
caused by abuse or improper use, maintenance, repair, installation or
alteration by a party other than Vendor or its authorized service center.

                 D.       Any Product or Software repaired or replaced by
Vendor in accordance with the foregoing warranty shall be returned to WorldCom

applicable warranty period or six (6) months after repair or replacement of the
Product, whichever is longer.

   4
                 F.       Product or Software repair services provided to
WorldCom by Vendor, outside the scope of the above specified warranties, are
warranted by Vendor for a period of ninety (90) days against defects in
material and workmanship, subject, however, to all other applicable terms,
limitations and conditions set forth herein.

         9.      CONTINUING AVAILABILITY OF TECHNICAL SUPPORT AND REPLACEMENT
AND REPAIRED PARTS.  Vendor shall provide WorldCom with continuing availability
of technical support, replacement parts and repaired parts in the following
manner:

                 A.       Technical Support - Vendor agrees to offer technical
support in the form of both telephone consultation and on-site assistance as
may be requested by WorldCom at Vendor's then current price (if any) for a
period of at least ten (10) years following delivery of the Product.  In the
event that the on-site assistance and/or telephone calls arise from a warranty
issue and during the applicable warranty period, the on-site assistance and/or
telephone calls shall be at no charge to WorldCom.

                 B.      Replacement Parts - Vendor agrees to:

                          (i)     Offer for sale newly manufactured systems,

which the Product is in current factory production;

prior to moving the Product from status of "current production" to a status of

provide for the expansion of previously delivered Product and to augment
WorldCom's spares pool for ongoing Product support;

                          (iii)   Provide another notice to WorldCom six (6)
months prior to moving the Product to a status of "manufacture discontinued."
Upon giving such six (6) month notice, if at any time that Vendor thereafter
fails or is unable to supply subassemblies, replacement modules and component
parts of the Product to WorldCom at the contractually agreed  price and within
sixty (60) days from the agreed delivery date for such items, WorldCom shall
have the right, in addition to any other right or remedy under this Agreement,
to require Vendor to supply WorldCom with all plans, documents, drawings,
technical specifications, parts lists and other documents as may be reasonably
necessary to enable and authorize WorldCom to obtain or manufacture such
subassemblies, replacement modules and component parts; and

                          (iv)    Continue to offer for sale to WorldCom, after
the Product is moved to the status of "manufacture discontinued,"
subassemblies, replacement modules and component parts for so long as
inventories of those items are available.

   5
                 C.       Repair Services - Vendor agrees to offer repair
services to WorldCom, subject to charges then generally billed by Vendor to its
customers, for so long as component parts to perform the repairs are available
and the repairs can be accomplished through reasonable efforts.

         10.     LIMITATION OF LIABILITY.  EACH PARTY SHALL BE LIABLE FOR
PHYSICAL INJURY TO INDIVIDUALS AND DAMAGE TO PROPERTY PROXIMATELY CAUSED BY
SUCH PARTY.  NEITHER VENDOR NOR WORLDCOM SHALL BE LIABLE TO THE OTHER FOR
INDIRECT, SPECIAL, INCIDENTAL, REMOTE OR CONSEQUENTIAL DAMAGES (INCLUDING BUT

         11.     *

                 A.       Vendor agrees that it shall defend, at its own
expense, all suits against WorldCom for *


and Vendor agrees that it shall pay costs incurred by WorldCom to defend such
an action, including its attorneys' fees, and shall pay all sums which, by
final judgment or decree in any such suits or through settlement, may be
assessed against WorldCom on account of * , provided that Vendor shall be given
timely written notice of any claims of any * and of any suits brought or 
threatened against WorldCom and authority to assume the defense thereof

may be without prejudice to the right of WorldCom to continue the use, as 
contemplated, of such Products.

                 B.       If in any such suit so defended *

         12.     SOFTWARE LICENSE.  Subject to the terms of the P&P Attachment,
Vendor agrees to grant a fully paid up, nonexclusive license for the use of any
Software furnished in conjunction with Vendor furnished Products in accordance
with the definitions set forth in the P&P Attachment and the following:





                                       5
   6
                 A        Limitations of License Grant - No title to or
ownership of the Software or any part thereof is conveyed to WorldCom.
Software furnished hereunder is to be used solely in conjunction with the
hardware Products with which the Software is furnished as it may be repaired
from time to time. WorldCom shall have no right to modify or reverse compile
any Software supplied hereunder by Vendor.

                 B.       Software as Proprietary Information - Software
furnished hereunder shall be treated as the exclusive property of Vendor, and
WorldCom shall hold such Software in confidence to the same extent that it
protects its own similar confidential or proprietary information.  WorldCom
shall not provide or make such Software available to any person, except to
those persons working with the Products purchased hereunder.  WorldCom shall
not reproduce or copy such Software in whole or in part except for backup and
archival purposes or as otherwise permitted in writing by Vendor.

                 C.       Term of Software License - This Software license
shall remain in effect for the full calendar measured term that beneficial use
is derived from the System.  Either party shall have the right to terminate
this license if the other party fails to comply with the terms and conditions
contained herein and WorldCom may voluntarily discontinue the use of the
licensed Software upon thirty (30) days' written notice to Vendor.  In either
event, WorldCom, upon written request from Vendor, shall immediately destroy
the original and any copies of the licensed Software, including any source
material which may have been furnished, and provide notice of such destruction
to Vendor.

                 D.       Assignment of Software License - The Software license
granted under this Agreement may not be transferred or assigned by WorldCom
without the prior consent of Vendor, which consent shall not be unreasonably
withheld or delayed.  However, WorldCom may assign such license (i) pursuant to
a sale of the System or substantially all assets of WorldCom to a third party
or (ii) to an entity, business organization or enterprise that either controls
WorldCom, is controlled by WorldCom or is under common control with WorldCom.

                 E.       Software Documentation - Vendor shall keep and
maintain a current copy of the Software source codes for, and any other
proprietary data information and documentation relevant to, the use and
maintenance of the Software licensed hereunder in secure vault storage at its
principal place of business designated herein.  Should Vendor at a future date
contemplate voluntary bankruptcy or be subject to an involuntary bankruptcy
proceeding or take other measures to terminate operations or terminate the
manufacture and sale of the Software, Vendor agrees that all security-vaulted
Software source codes, any other relevant Vendor proprietary data information
and documentation, and any licenses, rights and authorizations necessary in
utilizing, modifying or copying such, shall be promptly conveyed to WorldCom at
no charge.  Vendor acknowledges that if a trustee in bankruptcy or Vendor as a
debtor in possession rejects this Agreement, WorldCom may elect to retain its
rights under this Section 12.F as provided in 11 U.S.C. Section 365(n) of the
United States Bankruptcy Code (the "Bankruptcy Code").  Vendor further
acknowledges that all security-vaulted Software source codes, any other
relevant Vendor proprietary data information and





                                       6
   7
documentation, and any licenses, rights and authorizations necessary in
utilizing, modifying or copying such, shall be deemed to be "embodiments" of
the Software licensed hereunder as that term is used in Section 365(n) of the
Bankruptcy Code.  Should Vendor at a future date contemplate the sale of the
right to manufacture the hardware Products, including Software support thereof,
to a third party, Vendor agrees that it shall assign to the third party its
obligations under this license.  Should the third party fail to execute a
written assumption of Vendor's license obligations to WorldCom, Vendor's
security-vaulted Software source codes, any other relevant Vendor proprietary
data information and documentation, and any licenses, rights and authorizations
necessary in utilizing, modifying or copying such, shall be promptly conveyed
to WorldCom at no charge, prior to the execution by Vendor of any contract for
sale to any such third party.

                 F.       Software Upgrades - WorldCom shall be informed by
Vendor of Software Upgrades as specified herein.  Vendor shall supply Software
Upgrades at no charge to WorldCom during the term of the Software License set
forth in Section 12.D.  However, installation of any Software Upgrade is the
responsibility of WorldCom.

                 G.       Tax Determination - For the purposes of determining
tax liability, Software licensed hereunder is considered intangible property in
as much as it is merely a license to use a Vendor owned method of computer
operation and its tangible attributes are only incidental.

         13.     TAXES.

                 A.       The prices stated in this Agreement or in the P&P
Attachments do not include any state, federal or local sales, use or excise
taxes.  WorldCom expressly agrees to pay Vendor, in addition to the charges
herein specified, the amount of any such taxes which may be imposed upon or
payable by Vendor upon the sale of the Products.

                 B.       Should WorldCom consider any Products purchased
hereunder to be exempt from said taxes, WorldCom shall place on file with
Vendor valid tax exemption certificates for the state or other governmental
entity which may impose said taxes at the time of sale.

         14.     TITLE AND RISK OF LOSS.   Except as provided in Section 12 as
to Software, title and risk of loss or damage to the Products contained in each
shipment shall pass to WorldCom upon delivery thereof to a carrier acceptable
to both Vendor and WorldCom.  Shipping arrangements with such carrier shall be
handled by Vendor.  Vendor shall pack the Products for shipment in accordance
with its standard commercial packing practices.  However, if in-transit damage
results from Vendor's failure to adequately package the Products or to comply
with any custom packaging requested by WorldCom and agreed to by Vendor, Vendor
shall repair or replace the damaged Products at no charge to WorldCom.

         15.     SPECIFICATIONS.  Products furnished hereunder are represented
to perform in accordance with (a) the higher of Vendor's standard commercial
product





                                       7
   8
specifications and the additional specifications, if any, set forth in a P&P
Attachment and (b) any applicable federal regulatory agency requirements
(collectively referred to herein as "Specifications"), which Specifications
shall constitute the sole basis for technical acceptance of such Products by
WorldCom.

         16.     CONFIDENTIAL INFORMATION.

                 A.       Both parties hereto agree not to use or disclose to
anyone other than employees of the parties during the term of this Agreement
and for a period of five (5)  years thereafter, any Confidential Information
concerning the other party.  "Confidential Information" is information marked
as confidential by either party and which relates to either party's research,
development, trade secrets, or business affairs or that of any of its customers
or affiliates.  Each party agrees to indemnify the other party for any loss or
damage resulting from a breach of this provision.  However, the obligations of
the parties shall not extend to information and data which:

                          (i)     Was already known to either party prior to
commencing effort under this Agreement; or

                          (ii)    Was known or was generally available to the
public at the time of disclosure hereunder; or

                          (iii)   Becomes known or generally available to the
public (other than by act of the recipient) subsequent to its disclosure
hereunder; or

                          (iv)    Is disclosed or made available in writing to
the recipient by a third party having a bona fide right to do so; or

                          (v)     Is subject to disclosure by process of law.

                 B.       The provisions of this Section 16 may not be
construed to encompass data which the parties do not protect from disclosure to
third parties.

                 C.       The parties acknowledge that disclosure of any
confidential information other than as allowed by this Section 16 may give rise
to irreparable injury and may be inadequately compensable in monetary damages
and therefore the non-disclosing party shall be entitled to seek and to obtain
injunctive or other equitable relief against the breach or threatened breach of
such obligations, in addition to any other remedies which may be available.

         17.     SEVERABILITY.    If any term of this Agreement is found or
held to be contrary to the laws of any jurisdiction having control of its
construction, validity or enforcement or if it is found that any term is void
or voidable, then said term shall not apply and this Agreement shall be
construed as if said term were not present and its removal shall have no effect
on the remainder of the Agreement. In the event that any term is found to be





                                       8
   9
void or voidable, then Vendor and WorldCom shall in good faith renegotiate the
terms of the voided provision.

         18.     EXCUSABLE DELAYS.    Acts of God or of the public enemy,
earthquakes, hurricanes, acts of the U.S. Government in its sovereign capacity
(including, but not limited to the courts), fires, floods, epidemics,
quarantine restriction, strikes and freight embargoes and such similar
occurrences which cause failure by either party to perform hereunder, and
which, in every case, are beyond the reasonable control and are without the
fault or negligence of the party or its subcontractors, shall constitute an
excusable delay, provided that notice thereof is promptly given to the other
party.  In the event of delay resulting from any of the above causes, the
performance schedule shall be extended for a mutually agreed period reasonable
under the circumstances, but in no event longer than thirty (30) days. If delay
pursuant to this Section 18 continues for longer than thirty (30) days,
WorldCom may cancel this Agreement with no further liability and shall be
reimbursed by Vendor for any monies paid for Products not received due to such
delays.

         19.     GOVERNING LAW.   Except for laws relating to conflict of laws,
this Agreement, its formation and dispute resolution, construction and
interpretation shall be governed by the laws of the State of Delaware in the
United States of America.  The parties will attempt in good faith to promptly
resolve any controversy or claim arising out of or relating to this Agreement
or any subsequent performance by the parties before resorting to other remedies
available to them.  Any such dispute shall be referred to appropriate
executives of each party who shall have the authority to resolve the matter. If
the executives are unable to resolve the dispute, the parties may by agreement
refer the matter to an appropriate form of alternative dispute resolution such
as mediation.  If the parties cannot resolve the matter or if they cannot agree
upon an alternative form of dispute resolution, then either party may pursue
resolution of the matter through arbitration in accordance with the rules of
the American Arbitration Association applying the substantive law of the State
of Delaware without regard to any conflict of laws provisions.  The arbitration
will be governed by the United States Arbitration Act, 9, U.S.C. Section 1, et.
seq. and judgment upon the award rendered by the arbitrators may be entered by
any court with jurisdiction.  The arbitrators are not empowered to award
damages in excess of compensatory damages, and each party waives any damages in
excess of compensatory damages.  The parties agree to continue performance
during the pendency of any dispute, unless performance is terminated according
to Article 20 of this Agreement.  Notwithstanding the foregoing, either party
may bring a claim for injunctive relief as provided in any court of competent
jurisdiction without first submitting the claim to arbitration.


         20.     ASSIGNMENT.      Neither party shall assign any of the terms
and conditions hereof or any of its rights or obligations hereunder without the
prior written consent of the other party which shall not be unreasonably
withheld.  Notwithstanding the foregoing, however, either party may assign its
rights and obligations hereunder to an entity which controls, is controlled by
or is under common control with such party, or a successor





                                       9
   10
organization, which in all respects shall inure to such rights and be bound by
such obligations.

         21.     NOTICES.         Notices under this Agreement shall be in
writing and delivered to the representative of the party to receive notice
(identified below) at the address of the party to receive notice as it appears
below or as otherwise provided for by proper notice hereunder.   The effective
date for any notice under this Agreement shall be the date of delivery of such
notice (not the date of mailing) which may be effected by certified U.S. Mail

overnight delivery service, such as, FedEx or UPS:

         22.     INSURANCE.       Vendor shall obtain, pay for and maintain
insurance for the coverages and amounts of coverage not less than those set
forth below and shall provide WorldCom certificates issued by insurance
companies satisfactory to WorldCom to evidence such coverages.  Such
certificates shall provide that there shall be no termination, nonrenewal or
modification of such coverage without thirty (30) days' prior written notice to
WorldCom.

                 A.       Workers' Compensation insurance complying with the
law of the state or states of operation, whether or not such coverage is
required by law, and Employer's Liability insurance with limits of $500,000 per

                 In the event coverage is denied or reimbursement of a properly
presented claim is disputed by the carrier for insurance provided in A through
D above in connection with a claim relating to Vendor's performance of its
obligations under this Agreement, Vendor shall, upon written request, provide
WorldCom with a certified copy of the involved insurance policy or policies
within ten (10) business days of receipt of such request.

                 Vendor waives its right, and its underwriter's right, of
subrogation against WorldCom, its shareholders, officers, directors, agents and
employees thereof, WorldCom's affiliates and their shareholders, officers,
directors, agents and employees thereof, and WorldCom's subsidiaries and their
shareholders, officers, directors, agents and employees thereof, providing that
such waiver in writing prior to loss does not void or alter coverage, and such
waiver shall not affect Vendor's other rights or remedies under this Agreement
or under law.

                 Neither the insurance required herein nor the amount and type
of insurance maintained by Vendor shall change the extent of Vendor's liability
hereunder for injury, death, loss or damage.

                 Except as provided in this Agreement, WorldCom, its affiliates
and its subsidiaries shall not insure or be responsible for any loss or damage
to property of any kind owned or leased by Vendor or its employees, servants
and agents.  Any policy of insurance covering the property owned or leased by
Vendor against loss by physical damage shall provide that the underwriters have
given their permission to waive their rights of subrogation against WorldCom,
its affiliates and their directors, officers and employees, as well as their
subsidiaries including the directors, officers and employees thereof.

                     PRODUCTS AND PRICING ATTACHMENT NO. 1

THIS PRODUCTS AND PRICING ATTACHMENT NO. 1 (this "P&P ATTACHMENT") is made this
19 day of September, 1996, to that certain Basic Purchase Agreement between
WorldCom Network Services, Inc. ("WorldCom") and CIENA Corporation("VENDOR")
dated September 19, 1996 (the "AGREEMENT").  The following described Products
and relevant pricing terms shall be subject to the terms of the Agreement.
Unless otherwise specified herein, defined terms shall have the same meanings
as set forth in the Agreement.  However, in the event of a conflict between the
terms and conditions of the Agreement and the terms and conditions of this P&P
Attachment, this P&P Attachment shall control.

This P&P Attachment shall also replace and over-rule any previous Letters of
Commitment or Letters of Understanding that may exist between the two parties.


1.  TERM/COMMITMENT TO ORDER/EXCLUSIVITY.

Under this P&P Attachment, in exchange for the prices offered by CIENA, as
represented in Section 2 below, WorldCom agrees that Vendor shall be WorldCom's
exclusive supplier of dense (meaning greater than 4 channel) wave division
multiplexing system equipment and associated software ("WDM Systems") for a
period starting from the execution date of this P&P Attachment through December
31, 1997 ("EXCLUSIVE PERIOD").  This is not a commitment by WorldCom to order
any minimum quantity of WDM Systems; however, if WorldCom shall fail to
purchase from Vendor during such Exclusive Period Vendor's WDM Systems having
an aggregate price, * .  WorldCom's obligation to purchase exclusively from 
Vendor during the Exclusive Period is expressly subject to successful 
completion of the field trial currently in progress pursuant to that
Trial Evaluation Agreement between Vendor and WorldCom dated August 3, 1996.
Completion of such trial shall be determined to be successful or not solely at
the discretion of WorldCom, and WorldCom shall promptly notify Vendor in
writing of its determination.

WorldCom shall have the right to make Orders for the Products described herein
and place such Orders within sixty (60) months of the date of this P&P
Attachment and Vendor shall accept such Orders subject to the terms of the
Agreement and this P&P Attachment.  Orders shall indicate (1) quantity of items
ordered, (2) desired delivery date, (3) intended delivery site, and (4)
delivery site for Vendor's standard documentation. Orders placed byWorldCom
with Vendor shall not be binding upon Vendor until accepted in writing by a
duly authorized officer or employee of Vendor.  Such acceptance will occur
within five working days of receipt of order by Vendor.  If Vendor fails to
respond to the WorldCom individual purchasing agent placing the order  within
five working days, and if the purchase order otherwise conforms to the terms,
conditions and prices required under this Agreement, then such purchase order
is presumed to have been accepted by Vendor.






                                                                               1
   16
Upon execution of this Agreement and the P&P Attachment, WorldCom agrees that
Vendor may, at its election, make public announcement of the commencement by
WorldCom of a field trial of Vendor's WDM System equipment, with the wording of
such announcement subject to the reasonable approval of WorldCom.  Upon
successful completion of the field trial (which shall be deemed successful, if
at all, entirely at WorldCom's sole discretion), WorldCom agrees that Vendor
may make public announcement of the signing of this Agreement and the P&P
Attachment, with the wording of such announcement subject to the reasonable
approval of WorldCom.

of a copy of





                                     - 4 -

the dismissal of the lawsuit with prejudice. Woodruff shall bear its own
attorneys' fees and costs in connection with this litigation, and shall not
submit any such fees and costs as part of underwriting expenses in connection
with any Ciena IPO.

     6.          Regardless of whether there is any Ciena IPO, any SEC, NASD,
or otherwise legally required disclosure regarding this dispute or its
resolution shall be determined at the sole discretion of Ciena and its counsel.
Ciena agrees to provide a courtesy copy of any such disclosure to Woodruff,
except where prohibited by law or regulation.

     7.          Regardless of whether there is any Ciena IPO, this Settlement
Agreement shall supersede the Agreement and the Revised Agreement, copies of
which are attached hereto as Exhibits A and B. The Agreement and the Revised
Agreement and all rights and obligations of the parties thereunder are null and
void and the Agreements are terminated in all respects with the execution of
this Settlement Agreement. In connection therewith, Ciena shall sell to
Woodruff for $.01/share warrants to purchase 15,000 shares at $20.00/share upon
receipt of dismissal of the lawsuit with prejudice following execution of a
final settlement agreement in the form attached here to Exhibit C. The warrants
shall have a term of five (5) years and shall not be exercisable until the
first anniversary of the signing of a settlement agreement. The warrants shall
have a "net exercise" provision. The terms of the warrant, including without

III asserts any claims of any kind, whether in arbitration, litigation or any
other forum (including to the NASD or SEC), including, specifically, claims for
breach of this Settlement Agreement, against Ciena/Sevin or any of the entities
identified in paragraph 10 herein. Additionally, to the extent the warrants
have been exercised at the time Woodruff or WKW III asserts any such claim,
Ciena shall have an immediate right to recover from Woodruff and WKW III in
cash the greater of (a) the difference between the exercise price per share
under the warrants which have been exercised and the fair market value of Ciena
common stock at the time the warrants were exercised, or (b) the difference
between the exercise price per share under the warrants which have been
exercised and the fair market value of Ciena common stock at the time the claim
is made. Woodruff and WKW III acknowledge that the foregoing is intended to
assure that if Woodruff and WKW III assert claims against Ciena/Sevin or any of
the entities identified in paragraph 10, that they will do so with the
knowledge of the impact of such action on the unexercised warrants and on
Ciena's rights of recovery with respect to the exercised warrants.

     8.          Regardless of whether there is any Ciena IPO, Woodruff shall
dismiss with prejudice all claims asserted in the state court action and
federal court action against Ciena/Sevin on or before 4:00 p.m., Thursday,
August 22, 1996. On or before 4:00 p.m., Thursday, August 22, 1996, Woodruff

III covenant not ever to sue or otherwise assert claims against, from this day

Agreement or the indemnification provisions of the Indemnity Agreement,
including any request for injunctive relief, shall not be brought in court, but

successors, affiliates, and assigns do fully and finally release and forever

                                        September 29, 1993



Dr. David R. Huber
President
HydraLite Incorporated
P.O. Box 71
Jamison, PA  18929

Dear Dr. Huber:

          We are pleased to present HydraLite Incorporated ("HydraLite" or the
"Company") with the terms under which William K. Woodruff & Company,
Incorporated ("WKW") will serve as exclusive financial advisor to the Company
respecting a private financing of approximately $5 million for the Company.
Our advisory services will include, but are not limited to, the presentation of
HydraLite to certain qualified prospective institutional investors and
strategic investors and the evaluation of financing proposals submitted by such
investors solicited by WKW or brought to the Company's attention independently
of WKW, including parties contacted by HydraLite prior to the date hereof.  WKW
agrees to such engagement and for the term of this engagement we will use our
best efforts on the Company's behalf.

          Set forth below are the services WKW will perform in the course of
this assignment, the fees and expenses payable to WKW in exchange for these
services, and general terms and conditions of the engagement.

I.       SERVICES TO BE PROVIDED BY WKW

         1.      WKW will perform due diligence on the business, operations,
and financial condition and prospects of HydraLite and will assist the Company
in preparing a confidential offering memorandum ("Confidential Memorandum")
that will provide prospective investors with the necessary information that
will enable them to fairly evaluate HydraLite for financing.

         2.      Subject to the Company's prior approval, WKW will distribute
the Confidential Memorandum to a group of prospective investors jointly
selected by WKW and the Company.
   21
Dr. David R. Huber

         3.      WKW will develop, update and review with the Company on an
ongoing basis a list of parties that may be interested in investigating in
HydraLite, and contact only parties on this list that are approved by the
Company.

         4.      WKW will screen prospective investors based on their level of
interests, financial capability, compatibility, etc.  and enter into
preliminary negotiations with qualified prospective investors.

         5.      WKW will assist and advise the Company in negotiations with
prospective investors regarding price, type of securities and other material
factors.

         6.      WKW will assist the Company as requested by the Company, with
document preparation, procedural execution and closing of the transaction.

II.      FEE AND EXPENSE ARRANGEMENTS

The professional fees and expense reimbursement payable to WKW with respect to
this assignment are set forth below:

Should the Company consummate a transaction resulting in the financing, joint
venture, operating agreement, sale, merger or comparable transaction of
HydraLite with another person or entity (the "Transaction") during the period
of time this agreement is in effect, WKW shall be paid a contingent advisory fee
("Advisory Fee") in the amount of five percent (5%) of the amounts funded by
the prospective investors or, for consideration to HydraLite or its
shareholders not in cash, 5% of the amount determined by good faith negotiation
between HydraLite and WKW to have been received by HydraLite.  No amounts will
be owed to WKW for amounts funded on or before December 10, 1993 by Optelecom,
Inc. and/or its affiliates.  The Advisory Fee will be payable in cash at the
time of funding or receipt by HydraLite.

Upon closing of the Transaction contemplated hereby, the Company will sell to
WKW, for nominal consideration, warrants entitling WKW to purchase that number
of shares of common stock of the Company equal to five percent of the
fully-diluted common stock outstanding upon completion of the Transaction.
Such warrants shall have an exercise price per common share equal to the actual
or implied common share price in the Transaction, shall be exercisable for a
period of five years from the date of closing, and shall have standard
antidilution provisions and registration rights.
   22
Dr. David R. Huber
Septemer 29, 1993
Page 3



Also upon closing of the Transaction, the Company will grant to WKW a five-year
right of first refusal to serve as HydraLite's investment banker in any
transaction in which HydraLite retains an investment banker.  WKW's
compensation will be usual and customary in any such engagement.  In any case
in which the Company selects two or more investment bankers, WKW's share of
overall investment banking fees will be no less favorable to WKW than the total
of such fees divided by the number of underwriters or agents, as the case may
be, retained by HydraLite.

For its direct accountable expenses incurred in connection with this
assignment, such as telephone, travel, postage and express expenses, and
computer database access fees, WKW will earn common stock of HydraLite at the
rate of 0.0715% of the fully-diluted shares of HydraLite per $1,000 of such
expenses.  Such shares will be issued to WKW on the basis of such fully-diluted
shares as of the date of execution of this letter, and will be issued to WKW at
the earlier of the closing of the Transaction or the date of termination of
this engagement.  The maximum obtainable by WKW pursuant to the provision of
this paragraph will be 1.5% of the fully-diluted shares at such time.

III.     TERMS OF ENGAGEMENT RELATING TO FINANCING OF THE COMPANY

WKW will have the exclusive right for a period of 270 days from the date of
execution of this letter to serve as the Company's representative with respect
to the financing of HydraLite.  Any entity contacted by WKW or introduced to
the Company independently of WKW during the course of this assignment will be
deemed to be an interested party ("Interested Party").

Should this assignment be terminated prior to the financing of HydraLite by an
Interested Party and should the Company agree in principle to or subsequently
secure financing from or be sold to an Interested Party within an 18 month
period following the signing of this letter, then WKW shall be due the Advisory
Fee as contemplated in Section II above with respect to the financing.

IV.      INDEMNIFICATION

Recognizing that transactions of the type contemplated by this engagement
sometimes result in litigation and that the role of WKW is limited to acting as
of the Company's financial advisor, the Company will indemnify WKW, and its
directors, officers, agents and employees and controlling persons (hereinafter
referred to as "Indemnified Party") to the full extent lawful against any and
all
   23
Dr. David R. Huber
Septemer 29, 1993
Page 4



claims, losses and expenses as incurred (including reimbursement of all
reasonable fees and disbursements of Indemnified Party and cost of counsel and
of all Indemnified Party's reasonable travel and other out-of-pocket and per
diem expenses incurred in connection with the investigation or other
proceedings arising therefrom) arising out of WKW's engagement hereunder,
provided, however, that the Company shall not be liable in any such case to the
extent that any such claim, loss or expense is found in the final judgment by a
court and/or jury and/or arbitral body to have resulted from a breach of the
obligations of the Indemnified Party to the Company in circumstances involving
willfull bad faith or gross negligence in the performance of the services which
are the subject of this agreement.  The Company shall not be liable for any
settlment of any such action or claim without its express written consent.

V.       LACK OF INDEPENDENT VERIFICATION

During the course of this assignment, WKW may rely upon the opinions of experts
(including, but not limited to, independent public accounting firms) with
respect to the accuracy of certain data.  WKW will make no effort to
independently verify the accuracy of any expert opinons so relied upon.

VI.      CONFIDENTIALITY

All information supplied to WKW by the Company will be held in strict
confidence, whether or not marked confidential, as we understand that this
information is treated as highly confidential by you and is not normally
divulged to outside sources.  Moreover, WKW will make every reasonable effort to
ensure that the confidentiality of the Company data is protected by any
prospective investor to whom it is entrusted.  Each copy of the Confidential
Memorandum will be numbered and accounted for, and the immediate return of the
Confidential Memorandum and other accompanying data will be requested from any
prospective investor of the Company or any investor who indicates no further
interest in the financing contemplated herein.

VII.     AMENDMENTS

Both parties agree that this document can be modified or amended only through
written agreement of WKW and HydraLite.

                         REVISED COMPENSATION AGREEMENT


                 This Revised Compensation Agreement is entered into this 9th
day of April, 1994 by and between William K. Woodruff & Company, Incorporated
("Woodruff") and HydraLite Incorporated, a Delaware corporation ("HydraLite").

                                    RECITALS

                 A.       Woodruff and HydraLite are parties to an Agreement
dated September 29, 1993 (the "Original Agreement") in which Woodruff agreed to
assist HydraLite in raising approximately $5 million in a private financing in
return for specified compensation.

                 B.       To accommodate a private placement to be undertaken
by Spencer Trask Holdings Incorporated ("Spencer Trask") as private placement
agent to HydraLite, Woodruff and HydraLite entered into a letter agreement
dated November 22, 1993 and signed by Woodruff on November 29, 1993 (the
"Modification Agreement") that excepted from certain terms of the Original
Agreement the private placement to be undertaken by Spencer Trask and provided
for specific compensation to Woodruff with respect to such private placement.

                 C.       HydraLite is now negotiating an arrangement under
which it will receive first round financing from Sevin Rosen and/or other
venture capital firms or capital sources in an amount of at least $2 million
for shares of Preferred Stock ("First Round Financing") with a second round to
be raised through (1) a private placement to be undertaken by Spencer Trask as
private placement agent, or (ii) additional venture capital money.

                 D.       As an inducement to Sevin Rosen, other venture
capitalists or capital sources and Spencer Trask to invest in and undertake
activities on HydraLite's behalf, Woodruff and HydraLite desire to revise the
Original Agreement and the Modification Agreement upon the occurrence of the
First Round Financing, as further described below.

                 NOW, THEREFORE, for good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties do hereby
agree as follows:

                 Conditioned upon the occurrence of HydraLite's obtaining First
Round Financing of at least $2 million through the sale of a series of
preferred stock having substantially the rights and privileges contained in
Attachment A (the "Series A Preferred Stock"), and with the capitalization
resulting therefrom also substantially as shown in Attachment A, the following
shall occur:
   26
Revised Compensation Agreement
Page 2
April 9, 1994



                          a.      Except as provided below, the Original
Agreement and the Modification Agreement shall terminate upon the closing of
the First Round Financing and the simultaneous execution of the Warrant
Agreement by HydraLite and Woodruff and receipt by Woodruff of the Warrants
specified in paragraph b (below) and shall be of no further force or effect and
the parties shall have no further rights, duties or obligations arising out of
such agreements and no compensation or reimbursement of expenses, in whatever
form, shall be owed by HydraLite to Woodruff for the First Round Financing or
any future investments made in HydraLite (unless other separate agreements
between Woodruff & HydraLite are entered into).  The agreement contained in
Article VI.  (Confidentiality) of the Original Agreement shall remain in full
force and effect for two years after the First Round Financing, and the
provisions of Article IV (Indemnification) shall remain in full force and
effect without time limit.

                          b.      HydraLite shall issue to Woodruff warrants to
purchase 215,000 shares of HydraLite's Common Stock and execute the attached
Warrant Agreement dated April 9, 1994.  Such warrants shall be issued to
Woodruff simultaneously with the issuance of shares of Series A preferred Stock
to investors in the First Round Financing.  Issuance of these warrants to
Woodruff shall be the sole compensation of any type, except as provided in
paragraph c (below), including reimbursement of expenses, payable to Woodruff
in connection with the First Round Financing and any subsequent financing of
HydraLite (unless other separate agreements between Woodruff and HydraLite are
entered into).

                          c.      For a period concluding at the earlier of
seven (7) years from the date of closing of the First Round Financing or upon
the closing of HydraLite's initial public offering resulting in proceeds to
HydraLite of at least $10 million, in any transaction for which HydraLite
intends to retain one or more investment bankers, HydraLite shall give right of
first refusal to Woodruff for retention as an investment banker.  Giving
Woodruff right of first refusal shall mean, by way of example but not
limitation, that HydraLite shall first evaluate the proposals, advice and
qualifications of Woodruff for the transaction before approaching other
investments bankers, and if HydraLite agrees to undertake a transaction with
another credible such firm, Woodruff will have the right to participate in such
transaction provided that it agrees with and accepts the terms (e.g.,
valuation, investment banking compensation, etc.) accepted by HydraLite.
Woodruff's compensation will be usual and customary in any such engagement.  In
any case in which HydraLite selects two or more investment bankers, Woodruff's
share of overall investment banking fees and commissions will be no less
favorable to Woodruff than the total of such fees and commissions divided by
the number of underwriters or agents, as the case may be, retained by
HydraLite.

30 EXHIBIT C EXHIBIT 10.11 THIS WARRANT AND THE SECURITIES PURCHASABLE HEREUNDER HAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR UNDER THE SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION, AND MAY NOT BE OFFERED, SOLD, OR TRANSFERRED IN THE ABSENCE OF REGISTRATION OR UNLESS AN EXEMPTION FROM REGISTRATION IS AVAILABLE AND THE COMPANY RECEIVES AN OPINION OF COUNSEL SATISFACTORY TO IT TO SUCH EFFECT. CIENA CORPORATION WARRANT TO PURCHASE COMMON STOCK This certifies that, for the sum of $150.00, the receipt of which is hereby acknowledged, William K. Woodruff & Co., Incorporated or its registered assigns pursuant to Paragraph 10(b) hereof ("Holder") is entitled to subscribe for and purchase up to 15,000 shares (subject to adjustment as described herein) of fully paid and nonassessable Common Stock of CIENA Corporation, a Delaware corporation (the "Company"), upon exercise of this Warrant and subject to the provisions and upon the terms and conditions hereinafter set forth. As used herein, the term "Common Stock" shall mean the Company's presently authorized Common Stock and any securities into which such Common Stock may hereafter be exchanged. 1. TERM. This Warrant is exercisable, in whole or in part, at any time beginning August 22, 1997 until 5:00 P.M. New York City time on August 21, 2001, provided, however, that if at any time Holder or any of Holder's affiliates (including without limitation, William K. Woodruff, III) brings a claim or claims of any kind, whether in arbitration, litigation or any other forum, including specifically claims brought after conclusion of an IPO by the Company for breach of the Settlement Agreement and Mutual Release dated as of August 21, 1996 between Holder and the Company (the "Settlement"), against the Company, Sevin Rosen or any of the entities identified in paragraph 10 of the Settlement, this Warrant, to the extent unexercised, shall be null and void. Notwithstanding anything herein to the contrary, the Company shall use reasonable efforts to mail to the original Holder, by certified mail, return receipt requested, notice of the expiration date of this Warrant, no later than 15 days prior to the expiration date, but the failure of the Company to send or the Holder to receive such notice shall not affect the expiration hereof. 31 2. WARRANT PRICE. The purchase price payable for each share of Common Stock deliverable upon exercise of this Warrant (the "Warrant Price") is $20.00 per share, subject to adjustment as described in Section 5 hereof. 3. METHOD OF EXERCISE; PAYMENT; ISSUANCE OF NEW WARRANT. (a) Subject to Paragraph 1 hereof, the purchase right represented by this Warrant may be exercised by the Holder hereof, in whole or in part, by the surrender of this Warrant (with the Notice of Exercise form attached hereto as Exhibit 1 duly executed) at the principal office of the Company and by the payment to the Company of an amount equal to the then applicable Warrant Price per share multiplied by the number of shares then being purchased. The Warrant Price shall be paid in cash, by wire transfer or by check. (b) In lieu of delivering the Warrant Price as set forth in subparagraph (a), the Holder may exercise this Warrant by conversion, in whole or in part, into shares of Common Stock, by instructing the Company in writing ("Notice of Conversion") to deliver to the Holder (without payment by the Holder of any Warrant Price or of any other cash or consideration) that number of shares of Common Stock equal to the quotient obtained by dividing: (i) the value of this Warrant at the time the conversion right is exercised (determined by subtracting the aggregate Warrant Price in effect immediately prior to the exercise of the conversion right from the aggregate current market price (as determined in accordance with Paragraph 5(f) hereof) of the shares of Common Stock issuable upon exercise of this Warrant immediately prior to the exercise of the conversion right) by (ii) the current market price (as determined in accordance with Paragraph 5(e) hereof) of one share of Common Stock immediately prior to the exercise of the conversion right, and multiplying the quotient so obtained by a fraction equal to the portion of this Warrant which the Holder desires to exercise. The Notice of Conversion may be given by circling the appropriate option in the Notice of Exercise attached to this Warrant. (c) Each exercise of this Warrant shall be deemed to have been effected immediately prior to the close of business on the business day on which this Warrant shall have been surrendered to the Company, and at such time, the person or persons in whose name or names any certificate or certificates for shares of Common Stock (or other securities) shall be issuable upon such exercise, shall be deemed to have become the holder or holders of record thereof. 2 32 (d) In the event of any exercise of the rights represented by this Warrant, certificates for the shares of stock so purchased shall be delivered to the Holder hereof (or the transferee designated in the Notice of Exercise) within a reasonable time (but not later than three (3) business days after the date of such exercise) and, unless this Warrant has been fully exercised or expired, a new Warrant representing the portion of the shares, if any, with respect to which this Warrant shall not then have been exercised shall also be issued to the Holder hereof within such reasonable time. 4. STOCK FULLY PAID; RESERVATION OF SHARES. All Common Stock which may be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be fully paid and nonassessable, and free from all taxes, liens and charges with respect to the issue thereof. During the period within which the rights represented by this Warrant may be exercised, the Company will at all times have authorized, and reserved for the purpose of the issue upon exercise of this Warrant, a sufficient number of shares of its Common Stock to provide for the exercise of this Warrant in full. 5. ADJUSTMENT OF WARRANT PRICE AND NUMBER OF SHARES. The kind of securities purchasable upon the exercise of this Warrant and the Warrant Price shall be subject to adjustment from time to time upon the occurrence of certain events as follows: (a) Reclassification, Consolidation or Merger. In case of any reclassification or change of outstanding securities of the class issuable upon exercise of this Warrant (other than a change in par value, or from par value to no par value, or as a result of a subdivision or combination), or in case of any consolidation or merger of the Company with or into another corporation, (other than a merger (i) with another corporation in which the Company is the surviving corporation and which does not result in any reclassification or change of outstanding securities issuable upon exercise of this Warrant or (ii) a merger in which the Company is not the surviving corporation and holders of equity securities of the Company as a result of such merger receive more than 50% of the equity securities of the surviving corporation), or in case of any sale of all or substantially all of the assets of the Company, or in case of a share exchange in which 80% or more of the outstanding capital stock of the Company is exchanged for capital stock of another corporation, any of which transactions shall be referred to hereinafter as a "Corporate Transaction," the Company or such successor or purchasing company or entity, as the case may be, shall execute with the Holder of this Warrant an agreement pursuant to which the Holder of the Warrant shall have the right thereafter to purchase upon exercise of the Warrant the kind and amount of shares, and/or other securities and property that the Holder of the Warrant would have owned or have been entitled to receive after the happening of such Corporate Transaction had the Warrant been exercised immediately prior to such action. The agreement referred to in this subparagraph (a) shall provide for adjustments which shall be as nearly equivalent as 3 33 may be practicable to the adjustments provided for in this Paragraph 5. The provisions of this subparagraph (a) shall similarly apply to successive Corporate Transactions. (b) Subdivision or Combination of Shares. If the Company at any time while this Warrant remains outstanding and unexpired shall subdivide or combine its Common Stock, the Warrant Price shall be proportionately decreased in the case of a subdivision or increased in the case of a combination. (c) Stock Dividends. If the Company at any time while this Warrant is outstanding and unexpired shall pay a dividend with respect to Common Stock payable in, or make any other distribution with respect to Common Stock (except any distribution provided for in the foregoing subparagraph (a) or (b)), of Common Stock, then the Warrant Price shall be adjusted, from and after the date of determination of shareholders entitled to receive such dividend or distribution, to that price determined by multiplying the Warrant Price in effect immediately prior to such date of determination by a fraction (a) the numerator of which shall be the total number of shares of Common Stock outstanding immediately prior to such dividend or distribution and (b) the denominator of which shall be the total number of shares of Common Stock outstanding immediately after such dividend or distribution. (d) Adjustment of Number of Shares. Upon each adjustment in the Warrant Price, the number of shares of Common Stock purchasable hereunder shall be adjusted, to the nearest whole share, to the product obtained by multiplying the number of shares purchasable immediately prior to such adjustment in the Warrant Price by a fraction, the numerator of which shall be the Warrant Price immediately prior to such adjustment and the denominator of which shall be the Warrant Price immediately thereafter. (e) Current Market Price. For the purpose of any computation under this Warrant, the "current market price" per share of Common Stock on any date shall be deemed to be the average of the daily Closing Prices of the shares of Common Stock for the thirty (30) consecutive Trading Days preceding the applicable date. The "Closing Price" for each day shall be (i) the last reported sale price regular way or, in case no such sale takes place on such date, the average of the closing bid and asked quotations regular way, in either case on the New York Stock Exchange, or, if the Common Stock is not listed or admitted to trading on such exchange, on the principal national securities exchange on which the Common Stock is listed or admitted to trading; or (ii) if the Common Stock is not listed or admitted to trading on any national securities exchange, the last reported sale price regular way or, in case no such sale takes place on such day, the average of the closing bid and asked quotations regular way, in either case on the National Market System of the National Association of Securities Dealers, Inc. ("NASD"); or (iii) if not authorized for trading or quotation on such system, the average of the highest reported bid and lowest reported asked quotations as furnished by the NASD or similar organization if the NASD is no longer reporting such information; or (iv) if no such prices or quotations are available, the fair market value of the Common Stock as determined by good faith action of the Board of 4 34 Directors of the Company (whose determination shall be conclusive). A "Trading Day" shall be any day that the principal national securities exchange on which the Common Stock listed or admitted to trading is open for the transaction of business or, if not so listed or admitted, that the New York Stock Exchange is open for the transaction of business. (f) Adjustment for De Minimis Change. No adjustment in the Warrant Price shall be required unless such adjustment would require an increase or decrease of at least $0.05 in such price; provided, however, that any adjustments which by reason of this subparagraph (f) are not required to be made shall be carried forward and taken into account in any subsequent adjustment required to be made hereunder. 6. NOTICE OF ADJUSTMENTS. Whenever any Warrant Price shall be adjusted pursuant to Paragraph 5 hereof, the Company shall make a certificate signed by its chief financial officer setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated, and the Warrant Price or Prices after giving effect to such adjustment, and shall cause copies of such certificate to be mailed (by registered mail, return receipt requested, postage prepaid) to the Holder of this Warrant at the address specified in Paragraph 10(d) hereof or at any address provided to the Company in writing by the Holder of this Warrant. 7. FRACTIONAL SHARES. No fractional shares of Common Stock will be issued in connection with any exercise hereunder, but in lieu of such fractional shares the Company shall make a cash payment upon the basis of the Warrant Price then in effect and the fair market value of a full share as determined for this purpose by the Company's Board of Directors. 8. COMPLIANCE WITH SECURITIES ACT; DISPOSITION OF SHARES OF COMMON STOCK. The Holder of this Warrant, by acceptance hereof, agrees that this Warrant and the shares of Common Stock to be issued upon exercise hereof are being acquired for investment and that it will not offer, sell or otherwise dispose of this Warrant or any shares of Common Stock to be issued upon exercise hereof except under circumstances which will not result in a violation of the Securities Act of 1933, as amended (the "Act") and will provide to the Company upon its request an opinion of counsel satisfactory to the Company as to the exemption from the Act and applicable state securities laws applicable to such offer, sale or disposition. Upon exercise of this Warrant, the Holder hereof shall, if requested by the Company, confirm in writing, in a form satisfactory to the Company, that the shares of Common Stock so purchased are being acquired for investment and not with a view toward distribution or resale. This 5 35 Warrant and all shares of Common Stock issued upon exercise of this Warrant (unless registered under the Act) shall be stamped or imprinted with a legend substantially in the following form as well as any additional legends required by applicable securities laws or stockholders' agreements and similar agreements encumbering such shares: "THIS WARRANT AND THE SECURITIES PURCHASABLE HEREUNDER HAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR UNDER THE SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION, AND MAY NOT BE OFFERED, SOLD, OR TRANSFERRED IN THE ABSENCE OF REGISTRATION OR UNLESS AN EXEMPTION FROM REGISTRATION IS AVAILABLE AND THE COMPANY RECEIVES AN OPINION OF COUNSEL SATISFACTORY TO IT TO SUCH EFFECT." The Holder represents and warrants to the Company that it is an "accredited investor" as defined in Securities and Exchange Commission Rule 501 promulgated under the Act. 9. PIGGY-BACK REGISTRATION RIGHTS. (a) Piggy Back Registrations. If at any time after an initial public offering by the Company of its securities, the Company proposes to make a registered public offering of any of its securities under the Securities Act of 1933 (whether to be sold by the Company or by one or more third parties), the Company agrees on the first such occasion, to give written notice of the proposed registration to Holder, not less than 15 days prior to the proposed filing date of the registration statement, and at the written request of Holder delivered in writing to the Company within 15 days after the receipt of said notice; the Company agrees, subject to the provisions of this Section 9, to include in the registration statement and offering, and in any underwriting of the offering; all shares of Common Stock as may have been designated in the Holder's request. (b) Underwriter Discretion. If a registration in which the Holder has the right to participate pursuant to this Section 9 is an underwritten registration on behalf of the Company, and the managing underwriters advise the Company, that in their opinion, the number of securities requested to be included in the registration exceeds the number which can be sold in the offering, the Company shall allocate the number of shares to be included in the registration statement as follows: (i) first, all of the securities of the Company proposed to be sold by the Company, (ii) second, stockholders with piggy-back registration rights in existence as of the date hereof; and (iii) third, the Common Stock requested to be sold by Holder and all other requesting stockholders reduced, pro rata, in accordance with the percentage interests in the Company held by each of them. 6 36 (c) Information Required. The Company shall have no obligation to include shares of Common Stock owned by Holder in a registration statement pursuant to this Section 9, unless and until the Holder shall have furnished the Company with all information and statements about or pertaining to Holder in the reasonable detail and on a timely basis as is reasonably deemed by the Company to be necessary or appropriate with respect to the preparation of the registration statement. (d) Hold-back. In the event that the Company effects an underwritten public offering of any security, the Holder agrees, if requested by the managing underwriters, not to effect any public sale or distribution, including any sale pursuant to Rule 144 under the Securities Act of 1933, of any Common Stock (except as part of the underwritten offering) during the 180-day period commencing with the effective date of the registration statement for the offering. (e) Expenses. If, pursuant to Section 9 hereof, shares of Common Stock owned by any Holder are included in a registration statement, the Holder shall pay all transfer taxes, if any, relating to the sale of its shares, the fees and expenses of its own counsel, and its pro rata portion of any underwriting discounts or commissions or the equivalent thereof. The Company agrees to pay all expenses incident to the registration including all registration and filing fees, fees and expenses of compliance with securities or blue sky laws, underwriting discounts, fees and expenses (other than the Holder's pro rata portion of any underwriting discounts or commissions or the equivalent thereof), printing expenses, messenger and delivery expenses, and fees and expenses of counsel for the Company and all independent certified public accountants and other persons retained by the Company. (f) Indemnification. In the event that any share of Common Stock owned by a Holder are sold by means of a registration statement pursuant to this Section 9, the Company agrees to indemnify and hold harmless the Holder, each of its officers and directors, and each person, if any, who controls or may control the Holder within the meaning of the Act (the Holder, its officers and directors., and any other persons being hereinafter referred to individually as an "Indemnified Person" and collectively as "Indemnified Persons") from and against all demands, claims, actions or causes of action, assessments, losses, damages, liabilities, costs, and expenses, including, without limitation, interest, penalties, and reasonable attorneys' fees and disbursements, asserted against, resulting to, imposed upon or incurred by the Indemnified Person, directly or indirectly (hereinafter referred to in this Section 9 or, the singular as a "claim" and in the plural as "claims"), based upon, arising out of or resulting from any untrue statement of a material fact obtained in the registration statement or any omission to state therein a material fact necessary to make the statement made therein, in the light of the circumstances under which they were made, not misleading, except insofar as the claim is based upon, rises out of or results from information furnished to the Company in writing by the Holder for use in connection with the registration statement. The Holder agrees to indemnify and. hold harmless the Company, its officers and directors, and each person, if any, who controls or may control the Company within the meaning of the Act (the Company, it's officers and 7 37 directors, and any other persons also being hereinafter referred to individually as an "Indemnified Person" and collectively as "Indemnified Persons") from and against all claims based upon, arising out of or resulting from any untrue statement of a material fact contained in the registration statement or any omission to state therein a material fact necessary in order to make the statement made therein, in the light of the circumstances under which they were made, not misleading, to the extent that the claim is based upon, arises out of or results from information furnished to the Company in writing by the Holder for use in connection with the registration statement. Promptly after actually receiving definitive notice of any claim in respect of which an Indemnified Person may seek indemnification under this Section 9, the Indemnified Person shall submit written notice thereof to either the Company or the Holder, as the case may be (sometimes being hereinafter referred to as an "Indemnifying Person"). The omission of the Indemnified Person to so notify the Indemnifying Person of any claim shall not relieve the Indemnifying Person from any liability it may have hereunder except to the extent that (a) the liability was caused or increased by the omission, or (b) the ability of the Indemnifying Person to reduce the liability was materially adversely affected by the omission. In addition, the omission of the Indemnified Person so to notify the Indemnifying Person of any claim shall not relieve the Indemnifying Person from any liability it may have otherwise than hereunder. The Indemnifying Person shall have the right to undertake, by counsel or representatives of its own choosing, the defense, compromise or settlement (without admitting liability of the Indemnified Person) of and the claim asserted, the defense, compromise or settlement to be undertaken at the expense and risk of the Indemnifying Person, and the Indemnified Person shall have the right to engage separate counsel, at its own expense, whom counsel for the Indemnifying Person shall keep informed and consult with in a reasonable manner. In the event the Indemnifying Person shall elect not to undertake the defense by its own representatives, the Indemnifying Person shall give prompt written notice of the election to the Indemnified Person, and the Indemnified Person shall undertake the defense, compromise or settlement (without admitting liability of the Indemnified Person) thereof on behalf of and for the account and risk of the Indemnifying Person by counsel or other representatives designated by the Indemnified Person. In the event that any claim shall arise out of a transaction or cover any period or periods wherein the Company and the Holder shall each be liable hereunder for part of the liability or obligation arising therefrom, then the parties shall, each choosing its own counsel and bearing its own expenses, defend the claim, and no settlement or compromise of the claim may be made without the joint consent or approval of the Company and the Holder. Notwithstanding the foregoing, no Indemnifying Person shall be obligated hereunder with respect to amounts paid in settlement of any claim if the settlement is effected without the consent of the Indemnifying Person (which consent shall not be unreasonably withheld). 10. MISCELLANEOUS. (a) No Rights as Stockholder. No Holder of the Warrant or Warrants shall be entitled to vote or receive dividends or be deemed the Holder of Common Stock or any other securities of the Company which may at any time be issuable on the 8 38 exercise hereof for any purpose, nor shall anything contained herein be construed to confer upon the Holder of this Warrant, as such, any of the rights of a stockholder of the Company or any right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or to give or withhold consent to any corporate action (whether upon any recapitalization, issuance of stock, reclassification of stock, change of par value or change of stock to no par value, consolidation, merger, conveyance, or otherwise) or to receive notice of meetings, or to receive dividends or subscription rights or otherwise until the Warrant or Warrants shall have been exercised and the shares purchasable upon the exercise hereof shall have become deliverable, as provided herein. (b) Exchange, Transfer and Replacement of Warrant. Subject to Paragraph 8 hereof, the Holder may transfer or assign this Warrant, in whole but not in part and from time to time. Upon the surrender of the Warrant, properly endorsed, for registration of transfer or for exchange at the principal office of the Company, the Company at its expense will execute and deliver to or upon the order of the Holder thereof a new Warrant of like tenor, in the name of such Holder or as such Holder (upon payment by such Holder of any applicable transfer taxes) may direct, calling on the face thereof for the number of shares of Common Stock called for on the face of the Warrant. On receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction, or mutilation of this Warrant and, in the case of loss, theft or destruction, on delivery of any indemnity agreement or bond reasonably satisfactory in form and amount to the Company or, in the case of mutilation, on surrender and cancellation of this Warrant, the Company, at its expense, will execute and deliver, in lieu of this Warrant, a new Warrant of like tenor. (c) Amendments. Neither the Warrant nor any term hereof may be changed, waived, discharged or terminated without the prior written consent of the Holder. (d) Notice. Any notice given to either party under this Agreement shall be deemed to be given three (3) days after mailing, postage prepaid, addressed to such party at the address as such party may provide to the other. (e) No Impairment. The Company will not, by amendment of its Certificate of Incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company but will at all times in good faith assist in the carrying out of all the provisions of this Warrant. 9 39 (f) Governing Law.

this Warrant, to the extent unexercised, shall be null and void. Notwithstanding
anything herein to the contrary, the Company shall use reasonable efforts to
mail to the original Holder, by certified mail, return receipt requested, notice
of the expiration date of this Warrant, no later than 15 days prior to the
expiration date, but the failure of the Company to send or the Holder to receive
such notice shall not affect the expiration hereof.

               2.     WARRANT PRICE.

               The purchase price payable for each share of Common Stock
deliverable upon exercise of this Warrant (the "Warrant Price") is $20.00 per
share, subject to adjustment as described in Section 5 hereof.

               3.     METHOD OF EXERCISE; PAYMENT; ISSUANCE OF NEW WARRANT.

                      (a) Subject to Paragraph 1 hereof, the purchase right
represented by this Warrant may be exercised by the Holder hereof, in
whole or in part, by the surrender of this Warrant (with the Notice of Exercise
form attached hereto as Exhibit 1 duly executed) at the principal office of the
Company and by the payment to the Company of an amount equal to the then        
applicable Warrant Price per share multiplied by the number of shares then
being purchased. The Warrant Price shall be paid in cash, by wire transfer or   
by check.

                      (b) In lieu of delivering the Warrant Price as set forth
in subparagraph (a), the Holder may exercise this Warrant by conversion, in
whole or in part, into shares of Common Stock, by instructing the Company in
writing ("Notice of Conversion") to deliver to the Holder (without payment by
the Holder of any Warrant Price or of any other cash or consideration) that
number of shares of Common Stock equal to the quotient obtained by dividing:

                             (i) the value of this Warrant at the time the
                      conversion right is exercised (determined by subtracting
                      the aggregate Warrant Price in effect immediately prior to
                      the exercise of the conversion right from the aggregate
                      current market price (as determined in accordance with
                      Paragraph 5(f) hereof) of the shares of Common Stock
                      issuable upon exercise of this Warrant immediately prior
                      to the exercise of the conversion right) by

                             (ii) the current market price (as determined in
                      accordance with Paragraph 5(e) hereof) of one share of
                      Common Stock immediately prior to the exercise of the
                      conversion right,

and multiplying the quotient so obtained by a fraction equal to the portion of
this Warrant which the Holder desires to exercise.

               The Notice of Conversion may be given by circling the appropriate
option in the Notice of Exercise attached to this Warrant.

               (c) Each exercise of this Warrant shall be deemed to have been
effected immediately prior to the close of business on the business day on which
this Warrant shall have been surrendered to the Company, and at such time, the
person or persons in whose name or names any certificate or certificates for
shares of Common Stock (or other securities) shall be issuable upon such
exercise, shall be deemed to have become the holder or holders of record
thereof.

                                       2
   3

               (d) In the event of any exercise of the rights represented by
this Warrant, certificates for the shares of stock so purchased shall be
delivered to the Holder hereof (or the transferee designated in the Notice of
Exercise) within a reasonable time (but not later than three (3) business days
after the date of such exercise) and, unless this Warrant has been fully
exercised or expired, a new Warrant representing the portion of the shares, if
any, with respect to which this Warrant shall not then have been exercised shall
also be issued to the Holder hereof within such reasonable time.

               4.  STOCK FULLY PAID; RESERVATION OF SHARES.

                   All Common Stock which may be issued upon the exercise
of the rights represented by this Warrant will, upon issuance, be fully paid
and nonassessable, and free from all taxes, liens and charges with respect to
the issue thereof. During the period within which the rights represented by
this Warrant may be exercised, the Company will at all times have authorized,
and reserved for the purpose of the issue upon exercise of this Warrant, a
sufficient number of shares of its Common Stock to provide for the exercise of
this Warrant in full.

               5.  ADJUSTMENT OF WARRANT PRICE AND NUMBER OF SHARES.

                   The kind of securities purchasable upon the exercise of
this Warrant and the Warrant Price shall be subject to adjustment from time to
time upon the occurrence of certain events as follows:

               (a) Reclassification, Consolidation or Merger. In case of any
reclassification or change of outstanding securities of the class issuable upon
exercise of this Warrant (other than a change in par value, or from par value
to no par value, or as a result of a subdivision or combination), or in case of
any consolidation or merger of the Company with or into another corporation,
(other than a merger (i) with another corporation in which the Company is the
surviving corporation and which does not result in any reclassification or
change of outstanding securities issuable upon exercise of this Warrant or (ii)
a merger in which the Company is not the surviving corporation and holders of
equity securities of the Company as a result of such merger receive more than
50% of the equity securities of the surviving corporation), or in case of any
sale of all or substantially all of the assets of the Company, or in case of a
share exchange in which 80% or more of the outstanding capital stock of the
Company is exchanged for capital stock of another corporation, any of which
transactions shall be referred to hereinafter as a "Corporate Transaction," the
Company or such successor or purchasing company or entity, as the case may be,
shall execute with the Holder of this Warrant an agreement pursuant to which
the Holder of the Warrant shall have the right thereafter to purchase upon
exercise of the Warrant the kind and amount of shares, and/or other securities
and property that the Holder of the Warrant would have owned or have been
entitled to receive after the happening of such Corporate Transaction had the
Warrant been exercised immediately prior to such action. The agreement referred
to in this subparagraph (a) shall provide for adjustments which shall be as
nearly equivalent as

                                       3
   4

may be practicable to the adjustments provided for in this Paragraph 5. The
provisions of this subparagraph (a) shall similarly apply to successive
Corporate Transactions.

               (b) Subdivision or Combination of Shares. If the Company at any
time while this Warrant remains outstanding and unexpired shall subdivide or
combine its Common Stock, the Warrant Price shall be proportionately decreased
in the case of a subdivision or increased in the case of a combination.

               (c) Stock Dividends. If the Company at any time while this
Warrant is outstanding and unexpired shall pay a dividend with respect to Common
Stock payable in, or make any other distribution with respect to Common Stock
(except any distribution provided for in the foregoing subparagraph (a) or (b)),
of Common Stock, then the Warrant Price shall be adjusted, from and after the
date of determination of shareholders entitled to receive such dividend or
distribution, to that price determined by multiplying the Warrant Price in
effect immediately prior to such date of determination by a fraction (a) the
numerator of which shall be the total number of shares of Common Stock
outstanding immediately prior to such dividend or distribution and (b) the
denominator of which shall be the total number of shares of Common Stock
outstanding immediately after such dividend or distribution.

               (d) Adjustment of Number of Shares. Upon each adjustment in the
Warrant Price, the number of shares of Common Stock purchasable hereunder shall
be adjusted, to the nearest whole share, to the product obtained by multiplying
the number of shares purchasable immediately prior to such adjustment in the
Warrant Price by a fraction, the numerator of which shall be the Warrant Price
immediately prior to such adjustment and the denominator of which shall be the
Warrant Price immediately thereafter.

               (e) Current Market Price. For the purpose of any computation
under this Warrant, the "current market price" per share of Common Stock on any
date shall be deemed to be the average of the daily Closing Prices of the shares
of Common Stock for the thirty (30) consecutive Trading Days preceding the
applicable date. The "Closing Price" for each day shall be (i) the last reported
sale price regular way or, in case no such sale takes place on such date, the
average of the closing bid and asked quotations regular way, in either case on
the New York Stock Exchange, or, if the Common Stock is not listed or admitted
to trading on such exchange, on the principal national securities exchange on
which the Common Stock is listed or admitted to trading; or (ii) if the Common
Stock is not listed or admitted to trading on any national securities exchange,
the last reported sale price regular way or, in case no such sale takes place on
such day, the average of the closing bid and asked quotations regular way, in
either case on the National Market System of the National Association of
Securities Dealers, Inc. ("NASD"); or (iii) if not authorized for trading or
quotation on such system, the average of the highest reported bid and lowest
reported asked quotations as furnished by the NASD or similar organization if
the NASD is no longer reporting such information; or (iv) if no such prices or
quotations are available, the fair market value of the Common Stock as
determined by good faith action of the Board of

                                       4
   5

Directors of the Company (whose determination shall be conclusive). A "Trading
Day" shall be any day that the principal national securities exchange on which
the Common Stock listed or admitted to trading is open for the transaction of
business or, if not so listed or admitted, that the New York Stock Exchange is
open for the transaction of business.

               (f) Adjustment for De Minimis Change. No adjustment in the
Warrant Price shall be required unless such adjustment would require an increase
or decrease of at least $0.05 in such price; provided, however, that any
adjustments which by reason of this subparagraph (f) are not required to be made
shall be carried forward and taken into account in any subsequent adjustment
required to be made hereunder.

               6.  NOTICE OF ADJUSTMENTS.

                   Whenever any Warrant Price shall be adjusted pursuant to
Paragraph 5 hereof, the Company shall make a certificate signed by its chief
financial officer setting forth, in reasonable detail, the event requiring the
adjustment, the amount of the adjustment, the method by which such adjustment
was calculated, and the Warrant Price or Prices after giving effect to such
adjustment, and shall cause copies of such certificate to be mailed (by
registered mail, return receipt requested, postage prepaid) to the Holder of
this Warrant at the address specified in Paragraph 10(d) hereof or at any
address provided to the Company in writing by the Holder of this Warrant.

               7.  FRACTIONAL SHARES.

                   No fractional shares of Common Stock will be issued in
connection with any exercise hereunder, but in lieu of such fractional shares
the Company shall make a cash payment upon the basis of the Warrant Price then
in effect and the fair market value of a full share as determined for this
purpose by the Company's Board of Directors.

               8.  COMPLIANCE WITH SECURITIES ACT; DISPOSITION OF SHARES OF
                   COMMON STOCK.

                   The Holder of this Warrant, by acceptance hereof, agrees that
this Warrant and the shares of Common Stock to be issued upon exercise hereof
are being acquired for investment and that it will not offer, sell or otherwise
dispose of this Warrant or any shares of Common Stock to be issued upon exercise
hereof except under circumstances which will not result in a violation of the
Securities Act of 1933, as amended (the "Act") and will provide to the Company
upon its request an opinion of counsel satisfactory to the Company as to the
exemption from the Act and applicable state securities laws applicable to such
offer, sale or disposition. Upon exercise of this Warrant, the Holder hereof
shall, if requested by the Company, confirm in writing, in a form satisfactory
to the Company, that the shares of Common Stock so purchased are being acquired
for investment and not with a view toward distribution or resale. This


                                       5
   6

Warrant and all shares of Common Stock issued upon exercise of this Warrant
(unless registered under the Act) shall be stamped or imprinted with a legend
substantially in the following form as well as any additional legends required
by applicable securities laws or stockholders' agreements and similar agreements
encumbering such shares:

               "THIS WARRANT AND THE SECURITIES PURCHASABLE HEREUNDER HAVE BEEN
               ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE
               SECURITIES ACT OF 1933, AS AMENDED, OR UNDER THE SECURITIES LAWS
               OF ANY STATE OR OTHER JURISDICTION, AND MAY NOT BE OFFERED, SOLD,
               OR TRANSFERRED IN THE ABSENCE OF REGISTRATION OR UNLESS AN
               EXEMPTION FROM REGISTRATION IS AVAILABLE AND THE COMPANY RECEIVES
               AN OPINION OF COUNSEL SATISFACTORY TO IT TO SUCH EFFECT."

        The Holder represents and warrants to the Company that it is an
"accredited investor" as defined in Securities and Exchange Commission Rule 501
promulgated under the Act.

               9.     PIGGY-BACK REGISTRATION RIGHTS.

               (a) Piggy Back Registrations. If at any time after an initial
public offering by the Company of its securities, the Company proposes to make a
registered public offering of any of its securities under the Securities Act of
1933 (whether to be sold by the Company or by one or more third parties), the
Company agrees on the first such occasion, to give written notice of the
proposed registration to Holder, not less than 15 days prior to the proposed
filing date of the registration statement, and at the written request of Holder
delivered in writing to the Company within 15 days after the receipt of said
notice; the Company agrees, subject to the provisions of this Section 9, to
include in the registration statement and offering, and in any underwriting of
the offering; all shares of Common Stock as may have been designated in the
Holder's request.

               (b) Underwriter Discretion. If a registration in which the Holder
has the right to participate pursuant to this Section 9 is an underwritten
registration on behalf of the Company, and the managing underwriters advise the
Company, that in their opinion, the number of securities requested to be
included in the registration exceeds the number which can be sold in the
offering, the Company shall allocate the number of shares to be included in the
registration statement as follows: (i) first, all of the securities of the
Company proposed to be sold by the Company, (ii) second, stockholders with
piggy-back registration rights in existence as of the date hereof; and (iii)
third, the Common Stock requested to be sold by Holder and all other requesting
stockholders reduced, pro rata, in accordance with the percentage interests in
the Company held by each of them.

                                       6
   7

               (c) Information Required. The Company shall have no obligation to
include shares of Common Stock owned by Holder in a registration statement
pursuant to this Section 9, unless and until the Holder shall have furnished the
Company with all information and statements about or pertaining to Holder in the
reasonable detail and on a timely basis as is reasonably deemed by the Company
to be necessary or appropriate with respect to the preparation of the
registration statement.

               (d) Hold-back. In the event that the Company effects an
underwritten public offering of any security, the Holder agrees, if requested by
the managing underwriters, not to effect any public sale or distribution,
including any sale pursuant to Rule 144 under the Securities Act of 1933, of any
Common Stock (except as part of the underwritten offering) during the 180-day
period commencing with the effective date of the registration statement for the
offering.

               (e) Expenses. If, pursuant to Section 9 hereof, shares of Common
Stock owned by any Holder are included in a registration statement, the Holder
shall pay all transfer taxes, if any, relating to the sale of its shares, the
fees and expenses of its own counsel, and its pro rata portion of any
underwriting discounts or commissions or the equivalent thereof. The Company
agrees to pay all expenses incident to the registration including all
registration and filing fees, fees and expenses of compliance with securities or
blue sky laws, underwriting discounts, fees and expenses (other than the
Holder's pro rata portion of any underwriting discounts or commissions or the
equivalent thereof), printing expenses, messenger and delivery expenses, and
fees and expenses of counsel for the Company and all independent certified
public accountants and other persons retained by the Company.

               (f) Indemnification. In the event that any share of Common Stock
owned by a Holder are sold by means of a registration statement pursuant to this
Section 9, the Company agrees to indemnify and hold harmless the Holder, each of
its officers and directors, and each person, if any, who controls or may control
the Holder within the meaning of the Act (the Holder, its officers and
directors., and any other persons being hereinafter referred to individually as
an "Indemnified Person" and collectively as "Indemnified Persons") from and
against all demands, claims, actions or causes of action, assessments, losses,
damages, liabilities, costs, and expenses, including, without limitation,
interest, penalties, and reasonable attorneys' fees and disbursements, asserted
against, resulting to, imposed upon or incurred by the Indemnified Person,
directly or indirectly (hereinafter referred to in this Section 9 or, the
singular as a "claim" and in the plural as "claims"), based upon, arising out of
or resulting from any untrue statement of a material fact obtained in the
registration statement or any omission to state therein a material fact
necessary to make the statement made therein, in the light of the circumstances
under which they were made, not misleading, except insofar as the claim is based
upon, rises out of or results from information furnished to the Company in
writing by the Holder for use in connection with the registration statement. The
Holder agrees to indemnify and. hold harmless the Company, its officers and
directors, and each person, if any, who controls or may control the Company
within the meaning of the Act (the Company, it's officers and

                                       7
   8

directors, and any other persons also being hereinafter referred to individually
as an "Indemnified Person" and collectively as "Indemnified Persons") from and
against all claims based upon, arising out of or resulting from any untrue
statement of a material fact contained in the registration statement or any
omission to state therein a material fact necessary in order to make the
statement made therein, in the light of the circumstances under which they were
made, not misleading, to the extent that the claim is based upon, arises out of
or results from information furnished to the Company in writing by the Holder
for use in connection with the registration statement. Promptly after actually
receiving definitive notice of any claim in respect of which an Indemnified
Person may seek indemnification under this Section 9, the Indemnified Person
shall submit written notice thereof to either the Company or the Holder, as the
case may be (sometimes being hereinafter referred to as an "Indemnifying
Person"). The omission of the Indemnified Person to so notify the Indemnifying
Person of any claim shall not relieve the Indemnifying Person from any liability
it may have hereunder except to the extent that (a) the liability was caused or
increased by the omission, or (b) the ability of the Indemnifying Person to
reduce the liability was materially adversely affected by the omission. In
addition, the omission of the Indemnified Person so to notify the Indemnifying
Person of any claim shall not relieve the Indemnifying Person from any liability
it may have otherwise than hereunder. The Indemnifying Person shall have the
right to undertake, by counsel or representatives of its own choosing, the
defense, compromise or settlement (without admitting liability of the
Indemnified Person) of and the claim asserted, the defense, compromise or
settlement to be undertaken at the expense and risk of the Indemnifying Person,
and the Indemnified Person shall have the right to engage separate counsel, at
its own expense, whom counsel for the Indemnifying Person shall keep informed
and consult with in a reasonable manner. In the event the Indemnifying Person
shall elect not to undertake the defense by its own representatives, the
Indemnifying Person shall give prompt written notice of the election to the
Indemnified Person, and the Indemnified Person shall undertake the defense,
compromise or settlement (without admitting liability of the Indemnified Person)
thereof on behalf of and for the account and risk of the Indemnifying Person by
counsel or other representatives designated by the Indemnified Person. In the
event that any claim shall arise out of a transaction or cover any period or
periods wherein the Company and the Holder shall each be liable hereunder for
part of the liability or obligation arising therefrom, then the parties shall,
each choosing its own counsel and bearing its own expenses, defend the claim,
and no settlement or compromise of the claim may be made without the joint
consent or approval of the Company and the Holder. Notwithstanding the
foregoing, no Indemnifying Person shall be obligated hereunder with respect to
amounts paid in settlement of any claim if the settlement is effected without
the consent of the Indemnifying Person (which consent shall not be unreasonably
withheld).

               10.    MISCELLANEOUS.

               (a) No Rights as Stockholder. No Holder of the Warrant or
Warrants shall be entitled to vote or receive dividends or be deemed the Holder
of Common Stock or any other securities of the Company which may at any time be
issuable on the

                                       8
   9

exercise hereof for any purpose, nor shall anything contained herein be
construed to confer upon the Holder of this Warrant, as such, any of the rights
of a stockholder of the Company or any right to vote for the election of
directors or upon any matter submitted to stockholders at any meeting thereof,
or to give or withhold consent to any corporate action (whether upon any
recapitalization, issuance of stock, reclassification of stock, change of par
value or change of stock to no par value, consolidation, merger, conveyance, or
otherwise) or to receive notice of meetings, or to receive dividends or
subscription rights or otherwise until the Warrant or Warrants shall have been
exercised and the shares purchasable upon the exercise hereof shall have become
deliverable, as provided herein.

               (b) Exchange, Transfer and Replacement of Warrant. Subject to
Paragraph 8 hereof, the Holder may transfer or assign this Warrant, in whole but
not in part and from time to time. Upon the surrender of the Warrant, properly
endorsed, for registration of transfer or for exchange at the principal office
of the Company, the Company at its expense will execute and deliver to or upon
the order of the Holder thereof a new Warrant of like tenor, in the name of such
Holder or as such Holder (upon payment by such Holder of any applicable transfer
taxes) may direct, calling on the face thereof for the number of shares of
Common Stock called for on the face of the Warrant. On receipt of evidence
reasonably satisfactory to the Company of the loss, theft, destruction, or
mutilation of this Warrant and, in the case of loss, theft or destruction, on
delivery of any indemnity agreement or bond reasonably satisfactory in form and
amount to the Company or, in the case of mutilation, on surrender and
cancellation of this Warrant, the Company, at its expense, will execute and
deliver, in lieu of this Warrant, a new Warrant of like tenor.

               (c) Amendments. Neither the Warrant nor any term hereof may be
changed, waived, discharged or terminated without the prior written consent of
the Holder.

               (d) Notice. Any notice given to either party under this Agreement
shall be deemed to be given three (3) days after mailing, postage prepaid,
addressed to such party at the address as such party may provide to the other.

               (e) No Impairment. The Company will not, by amendment of its
Certificate of Incorporation or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed hereunder by the Company but will at all
times in good faith assist in the carrying out of all the provisions of this
Warrant.

- iii - 4 LEASE AGREEMENT THIS LEASE AGREEMENT ("Lease") is made this 1 day of November, 1996, by and between the AETNA LIFE INSURANCE COMPANY (the "Landlord") and CIENA CORPORATION (the "Tenant"), a Delaware corporation. WITNESSETH, that for good and valuable consideration, the Landlord hereby leases to the Tenant, and the Tenant hereby leases from the Landlord, an agreed-upon amount of 96,566 rentable square feet of space shown on Exhibit A hereto (the "Premises"), comprising all of the rentable space in the office building (the "Building") which, together with 408 parking spaces adjacent to such Building, landscaping and other improvements, are shown on Exhibit B hereto and located at 920 Elkridge Landing Road in Anne Arundel County, Maryland (collectively the "Property"), all upon the following terms and conditions: ARTICLE I - TERM Section 1.01 Length. This Lease shall be for a term (the "Term") which begins on that date (the "Commencement Date") which is the earlier of(i) March 1, 1997 (the "Target Date"), or (ii) 150 days after the first date on which the Tenant commences construction of the Space Improvements to the Premises as described in Section 5.01 below, subject to Section 5.01(A)(3) below. The Term shall expire on that date which is 10 years after such Commencement Date (the "Expiration Date"). In the event that the Tenant enters into occupancy of the Premises prior to the Commencement Date for any purpose, then all terms of this Lease shall apply to such occupancy, except that Tenant shall not be obligated to pay Base Rent or Real Estate Taxes (defined herein) for such period, and the Tenant's rental obligations shall be limited to the payment of any electricity or other utility charges incurred with respect to the Building and allocable to such period prior to the Commencement Date. In addition, to the extent that Tenant occupies the Premises prior to the Commencement Date for the purpose of conducting business therein, Tenant shall be obligated to pay the costs of snow removal, building repairs and landscaping, on-site maintenance and operations personnel, and electricity and other utilities used in connection with the common areas of the Building. All such utility and other costs for the period prior to the Commencement Date shall be paid by Tenant as Additional Rent (defined herein). Section 1.02 Confirmation. Landlord shall, within 30 days after the commencement of the Term, confirm to Tenant in writing the actual dates of the Commencement Date and the Expiration Date. In the event that Tenant disagrees with such dates as stated in the confirmation notice from Landlord, - 1 - 5 Tenant shall, within 15 days after Landlord's notice, notify Landlord in writing as to Tenant's objections. If Tenant fails to so notify Landlord of any objection within this 15 day period, the dates set forth in the Landlord's notice shall govern for purposes of this Lease. If Tenant does notify Landlord of an objection within this 15 day period, the parties shall attempt to resolve the disagreement within 21 days after the Tenant's notice of objection. In the event that the parties are unable to agree within this 21 day period, then either party shall have the right to have the applicable dates determined by arbitration by giving written notice to the other before expiration of the 21 day period (an "Arbitration Notice"). If neither party delivers an Arbitration Notice before expiration of the 21 day period, then the dates set forth in the Landlord's initial notice shall govern for purposes of this Lease. If one of the parties does deliver an Arbitration Notice within the 21 day period, then Landlord and Tenant shall designate an independent party with experience in adjudicating at least one arbitration case (the "Arbiter"). The Arbiter shall conduct such hearings and investigations as he or she may deem appropriate but, in all events, reach a decision binding on the parties within 30 days after being designated. Furthermore, in the case of any such dispute regarding the Commencement Date and Expiration Date, Tenant shall not withhold payments of rent or other charges hereunder, and any Base Rent paid but ultimately attributable to the period before the actual Commencement Date as determined by the Arbiter shall be applied toward the next installment of Base Rent due hereunder. Landlord and Tenant shall divide evenly the fees of the Arbiter incurred during the foregoing procedures. Section 1.03 Options to Renew. Tenant shall have two successive options to renew the Term of the Lease commencing upon its expiration for an additional period of 5 years each (each a "Renewal Term," which shall be deemed to be part of the Term), subject to the following terms: (A) Tenant's options to renew shall apply to the entire Premises and not any lesser portion thereof. (B) In order to exercise each such option to renew the Lease, Tenant must give Landlord written notice of its election to renew not earlier than 365 days and not later than 330 days before the expiration of the then-current Term. If the applicable option is exercised in accordance with the terms of this section, the Renewal Term shall be under all of the same terms and conditions as are contained in the Lease, except that the Base Rent applicable during the Renewal Term shall be at the then-prevailing market rate of rent and all other charges for comparable office space in the area of the Baltimore-Washington International Airport, taking into account any and all factors (e.g., condition of space and improvements, parking and other facilities, location of the Building, length of term, Tenant's needs as a large user of space, etc.). If Tenant exercises the applicable option by the - 2 - 6 time required above, then Landlord shall notify Tenant in writing of the market rate of Base Rent to apply during the Renewal Term, as determined by real estate brokers or other professionals selected by Landlord, within 15 days after Tenant's notice of exercise. Landlord shall accompany such notice with backup information as to the analysis on which such determination of the market rate is based. (C) With respect to either of the foregoing options to renew, if Tenant does not accept Landlord's determination of the market rate of Base Rent contained in the Landlord's notice, then Tenant shall notify Landlord of this fact in writing within 15 days after the Landlord's notice. If Tenant so notifies Landlord within this 15 day period, then the parties shall attempt to resolve their differences regarding the Landlord's figure and agree upon the market rate of Base Rent within 30 days after the Tenant's notice of non-acceptance. In the event that the parties cannot agree upon the market rate within this 30 day period, then the Tenant shall have the right, upon written notice to Landlord given prior to the expiration of such 30 day period, to either (1) rescind the exercise of the applicable option, in which case the option shall be null and void, or (2) elect to have the market rate determined by arbitration as described in subsection (D) below. If the Tenant fails to notify the Landlord that it does not accept the Landlord's determination of the market rate within the period of 15 days after the Landlord's initial notice as described above, or if the Tenant does so notify the Landlord but Tenant does not either rescind the option or elect to have the market rate determined by arbitration within the 30 day period described above (and the parties are unable to agree upon the market rate in this period), then the figure for the market rate set forth in the Landlord's initial notice to the Tenant shall govern for the Renewal Term. (D) If with respect to either of the options described above, Tenant elects to have the market rate of Base Rent to apply during the Renewal Period determined by arbitration, the market rate of Base Rent shall be established by a panel of 3 licensed real estate brokers, each of whom shall have a minimum of 7 years of experience in the commercial real estate brokerage business in the region in which the Building is located. One such broker shall be selected by Landlord within 7 days after Tenant's election of arbitration, one such broker shall be selected by Tenant within the same 7 day period, and the third such broker shall be selected by the first two within 7 days after the first two are so selected. Each broker, within 21 days after the third broker is selected, shall submit his or her determination of the market rate of Base Rent, which shall be based on the criteria described in subsection (B) of this section above, and the average of the two closest determinations shall be binding on the parties for purposes of calculating Base Rent during the Renewal Period.

In such event, the Commencement Date and Expiration Date shall be postponed for a period equaling the length of such delay. However, if any delay in completion of the Landlord's Work is caused by Tenant, then Tenant shall commence all - 13 - 17 of its obligations hereunder (including the payments of Rent), and all terms herein shall be effective and binding, on that date reasonably calculated by Landlord or its contractor as the date on which Landlord would have substantially completed the Landlord's Work if not for such delay.

Such plans and specifications shall be submitted to Landlord within 30 days after the date hereof, and Landlord shall review and either approve or notify Tenant of proposed changes thereto within 10 days after receiving such plans. Landlord agrees to not unreasonably withhold its approval of Tenant's plans and specifications, and Tenant agrees to make any changes to such plans and specifications reasonably requested by Landlord. However, with respect to any alterations to the Building exterior proposed by Tenant, Landlord shall have the right in its sole and absolute subjective discretion to require modifications or, in the absence thereof, withhold consent on the basis of aesthetic considerations. (2) Promptly after the plans and specifications have been finalized, Tenant shall solicit bids and enter into written contracts with a contractor or contractors for the construction of such improvements and with other professionals for appropriate services in connection therewith.

However, any delays in Tenant's completion of such improvements beyond the Target Date set forth in Section 1.01 shall not delay the Commencement Date, which shall be determined as set forth in Section 1.01. (C) All costs and expenses of designing and constructing the Space Improvements described in subsection (B) above shall be paid as follows: (1) Landlord shall provide and pay an allowance (the "Allowance") of $20.10 per square foot of the Premises towards (i) the costs of designing the Space Improvements and preparing plans and specifications therefor, and (ii) the costs of constructing the Space Improvements, including but not limited to all fees, costs and expenses paid under construction contracts and subcontracts, a supervision and management fee of $0.40 per rentable square foot of the Premises, costs and expenses, the costs of materials, supplies, permits and other items, and any other out-of-pocket expenditures incurred in any connection with such construction. Such Allowance shall not be paid for the Landlord's Work or for any other costs or purposes. Landlord represents to Tenant that Landlord has sufficient funds or credit available to pay the Allowance in its entirety. (2) Tenant shall pay any and all costs of designing and constructing the Space Improvements which are in excess of the Allowance. - 15 - 19 (3) Landlord shall disburse the Allowance in installments to pay for completed work, and directly to the professionals, contractors and other parties performing work on the Space Improvements, upon presentation for each disbursement of (i) a requisition substantially in the form of AlA Requisition Forms G702 and G703, including a description of all completed work for which payment is requested, the amount requested with a breakdown by each trade comprising the work, and the percentage of the entire project completed after taking into account all such work, (ii) approval by Landlord's construction manager of the requisition, (iii) conditional lien waivers from all parties for whom such payment is requested releasing all liens which may arise on account of the work performed by such parties to the date of the request for payment, and (iv) unconditional lien waivers covering all work up to and including the immediately preceding payment. Each disbursement of a portion of the Allowance shall be made within 21 days after presentation of the required items. With respect to each contract or subcontract item comprising part of the Space Improvements, a retainage of 10% shall be withheld from the applicable disbursements until such contract or subcontract item is 75% complete, at which time the retainage with respect to such item shall be reduced to 5%, with the retainage to be fully paid and disbursed upon (i) completion of the Space Improvements as required by the applicable contract(s), (ii) delivery of unconditional lien waivers as described above for all work comprising the improvements, and (iii) issuance of a certificate of occupancy or other applicable approval by the local authorities permitting occupancy of the Premises by Tenant for business (unless any delay in issuance of the certificate of occupancy is solely due to the failure of the Landlord to complete the Landlord's Work, in which event this item (iii) shall not apply). Section 5.02 Acceptance. Except for the Landlord's Work which is to be completed as is described in Section 5.01(A) above, Tenant acknowledges that it shall be leasing the Premises hereunder "as-is" without warranty or representation of any kind except as may be expressly stated in this Lease. Section 5.03 Tenant's Alterations. The Tenant shall not make any alteration, addition or improvement to the Premises, whether structural or nonstructural and including any signs or other items which may be visible from the exterior of the Premises (but not including any interior cosmetic or decorative alterations), without the Landlord's prior written consent, which shall not be unreasonably withheld. Tenant shall provide such drawings, plans and specifications as are requested by Landlord in reviewing any such proposed improvements. Landlord agrees to respond to any request for approval within 15 days after receipt of all plans and information relevant thereto; however, Landlord shall have the right to place conditions upon the granting of its approval of any alteration or improvement, including but not limited to requirements that the work be performed only by bonded - 16 - 20 contractors or that Landlord itself perform the work with the Tenant to reimburse Landlord's out-of-pocket costs of the alteration or improvement. If the Landlord consents to any such proposed alteration, sign, addition or improvement, it shall be made at the Tenant's sole expense (and the Tenant shall hold the Landlord harmless from any cost incurred on account thereof), and at such time and in such manner as to not unreasonably interfere with the use and enjoyment of the remainder of the Property by any other tenant (if any).

Notwithstanding anything herein to the contrary, if the interruption in any service continues for a period of 5 days due to the fault of Landlord, and the Premises are rendered untenantable thereby, then all Rent shall abate thereafter until the applicable service is restored.

ARTICLE VIII - CASUALTIES Section 8.01 General. If the Premises or Building are damaged by fire or other casualty during the Term, then the following shall apply: (A) The Landlord shall restore the Premises or Building with reasonable promptness, taking into account the time required by the Landlord to effect a settlement with, and to procure any insurance proceeds from, any insurer against such casualty, to substantially the same condition as existed immediately before such casualty. Landlord may temporarily enter and possess any or all of the Premises for such purpose. The Landlord shall not be obligated to repair, restore or replace any fixture, improvement, alteration, furniture or other property owned or installed by the Tenant. (B) The times for commencement and completion of any such restoration shall be extended for the period of any delay arising due to force majeure causes beyond the Landlord's control. If the Landlord undertakes to restore the Premises or Building, but such restoration cannot be accomplished within 210 days after the date of casualty, as determined by estimate of Landlord upon such casualty, then Tenant may terminate this lease by giving written notice thereof to the Landlord within 15 days after receipt of such estimate from Landlord. (C) From the time of such casualty to the completion of restoration as described above, Tenant's rental obligations shall be abated proportionately from that portion of the Premises which is rendered untenantable as a result of the casualty. However, if more than 75% of the Premises are rendered untenantable by such casualty, then, at Tenant's option, the entire Building shall be deemed untenantable, and such rent - 19 - 23 abatement shall apply to the entire Building (except with respect to any space actually used by Tenant).

Section 8.03 Tenant's Negligence. Subject to the provisions of Section 4.03 hereof, if any such damage to the Premises, the Building or Property are caused by or result from the negligent or intentional act or omission of the Tenant or any of its employees, contractors, agents, invitees or licensees, then (a) the Rent shall not be abated or apportioned as aforesaid, and (b) the Tenant shall pay to the Landlord upon demand, as Additional Rent, if and only to the extent not paid by insurance, the cost of (i) any repairs and restoration made or to be made as a result of such damage, or (ii) (if the Landlord elects not to restore the Building) any damage or loss which the Landlord incurs as a result of such damage.

If any or all of the Premises are taken by the exercise of any power of eminent domain or are conveyed to or at the direction of any governmental entity under a threat of any such taking (each of which a "Condemnation"), the Landlord shall be entitled to collect from the condemning authority thereunder the entire amount of any award or consideration for such conveyance, without deduction therefrom for any leasehold or other estate held by the Tenant under this Lease. The Landlord shall be entitled to conduct any condemnation proceeding and any settlement connected therewith free of interference from the Tenant, and the Tenant - 20 - 24 hereby waives any right which it has to participate therein. However, the Tenant may seek, in a separate proceeding, a separate award on account of any damages or costs incurred by the Tenant as a result of any such Condemnation. Section 9.02 Effect of Condemnation. If (a) all of the Premises are covered by a Condemnation, or (b) any part of the Premises is covered by a Condemnation and the remainder is insufficient for the reasonable operation of the Tenant's business, or (c) any of the Building is covered by a Condemnation and, in the Landlord's reasonable opinion, it would be impractical to restore the remainder thereof, or (d) any of the rest of the Property is covered by a Condemnation and, in the Landlord's reasonable opinion, it would be impractical to continue to operate the remainder of the Property thereafter, then, in any such event, the Term shall terminate on the date on which possession of the property covered by such Condemnation is taken by the condemning authority thereunder, and all Rent (including any Additional Rent and other charges payable hereunder) shall be apportioned and paid to such date. If there is a Condemnation and the Term does not terminate pursuant to the foregoing provisions of this subsection, the operation and effect of this Lease shall be unaffected by such Condemnation, except that the Base Rent shall be reduced in proportion to the square footage of floor area, if any, of the Premises covered by such Condemnation.

Landlord shall respond to Tenant's request for approval or disapproval of the Transfer within 20 days after Landlord receives the request and all documents and information required above.

Section 10.03 Liability to Landlord. Tenant hereby agrees that notwithstanding anything in this Lease to the contrary, and regardless of whether or not Landlord's consent is required hereunder, no Transfer shall be valid or effective unless and until the Transferee agrees in a written document, in form and substance reasonably satisfactory to Landlord, that the Transferee shall (1) in the case of a subletting of any part of the Premises, observe and perform all duties, obligations and liabilities of the Tenant under the terms of this Lease as such terms relate to the space subleased, or (2) in the case of all other Transfers, observe and perform all duties, obligations and liabilities of the Tenant under the terms of this Lease. In addition, no Transfer of any kind, regardless of whether or not Landlord's consent thereto is required hereunder, shall serve to relieve or release the Tenant in any way from full and direct liability for the timely performance of all of the Tenant's duties and obligations under this Lease. Section 10.04 Excess Rents. In the event that Tenant effects any Transfer to a third party entity which is not affiliated with Tenant and at any time receives rent and/or other consideration on a periodic basis which exceeds that which Tenant is obligated to pay to Landlord hereunder, Tenant shall pay to Landlord 50% of such excess rent or other consideration, after - 22 - 26 recovering the leasing commissions, tenant improvement costs and any other out-of-pocket costs of consummating such Transfer, when and as received by Tenant.

Any Mortgagee may at any time subordinate the lien of its Mortgage to the operation and effect of this Lease without obtaining the Tenant's consent thereto, in which event this Lease shall be deemed to be senior to such Mortgage without regard to their respective dates of execution, delivery and/or recordation among the land records of the jurisdiction in which the Property is located. Section 12.03 Estoppel Certificate. Landlord and Tenant shall each, from time to time within 10 business days after request by the other (or any Mortgagee), execute, acknowledge and deliver (or, at the Landlord's request, to any existing or prospective purchaser, assignee or Mortgagee) a written certification (a) that this Lease is unmodified and in full force and effect (or, if there has been any modification, stating the nature of such modification), (b) as to the dates to which the Base Rent and any Additional Rent and other charges arising hereunder have been paid, (c) as to the amount of any prepaid Rent or any credit due to the Tenant hereunder, (d) that the Tenant has accepted possession of the Premises and all improvements thereto are as required hereunder, and the date on which the Term commenced, (e) as to whether, to the best knowledge, information and belief of the party executing the certificate, the Landlord or the Tenant is then in default in performing any of its obligations hereunder (and, if so, specifying the nature of each such default), and (f) as to any other fact or condition reasonably requested.

No reentry or taking possession of the Premises by Landlord shall be construed as an election on its part to terminate this Lease unless a written notice of such intention be given to Tenant or unless the termination thereof be decreed by a court of competent jurisdiction. Notwithstanding that Landlord may have re-leased the Premises without termination, Landlord may at anytime thereafter elect to terminate this Lease for any previous default. If the Premises or any part thereof is re-leased, Landlord shall not be liable for, nor shall Tenant's obligations hereunder be diminished by reason of, any failure by Landlord to relet the Premises or any failure by Landlord to collect any rent due upon such reletting. No action taken by the Landlord under the provisions of this section shall operate as a waiver of any right which the Landlord would otherwise have against the Tenant for the Rent hereby reserved or otherwise, and the Tenant shall at all times remain responsible to the Landlord for any loss and/or damage suffered by the Landlord by reason of any Event of Default. However, nothing in this Lease shall restrict or prohibit Tenant from taking any legal action of any kind to protect its rights available by virtue of this Lease or applicable law, all of which rights are reserved by Tenant in all respects. Section 14.04 Damages. Upon any Event of Default, Tenant shall remain liable to the Landlord for the following amounts: (a) any Rent of any kind whatsoever which may have become due with respect to the period in the Term which has already expired, (b) all Rent which becomes due during the remainder of the Term, (c) all costs, fees and expenses incurred by Landlord in leasing the Premises to others from time to time, including but not limited - 29 - 33 to leasing commissions, construction and other build-out costs, design and permitting costs and the like, and (e) all costs, fees and expenses incurred by Landlord in pursuit of its remedies hereunder, including but not limited to attorneys' fees and court costs. All such amounts shall be due and payable immediately upon demand by Landlord and shall bear interest at 18% per annum until paid. Furthermore, at Landlord's option, Tenant shall be obligated to pay, in lieu of item (b) above in this Section 14.04, an amount (the "Substitute Amount") which is equal to (i) the present value of all Rent which would become due during the remainder of the Term, including all Additional Rent which shall be deemed to continue and increase over such remainder of the Term at the average rate of increase occurring over the then-expired portion of the Term, with such present value to be determined by discounting at an annual rate of interest which is equal to the bond- equivalent yield for the most recent auction of U.S. Treasury Bills with a 1-year maturity, minus (ii) the fair market rental value of the Premises for the remainder of the Term, as determined by independent real estate professional selected by Landlord. Tenant and Landlord acknowledge and agree that payment to Landlord of the foregoing Substitute Amount a reasonable forecast of the actual damages which will be suffered by Landlord in case of an Event of Default by Tenant, which actual damages are otherwise difficult or impossible to ascertain, and therefore such payment constitutes liquidated damages and not a penalty. Any suit or action brought by Landlord to collect any such liquidated damages shall not in any manner prejudice any other rights or remedies of Landlord hereunder. Section 14.05 Landlord's Lien. Tenant hereby grants to Landlord an express first and prior contract lien and security interest on all fixtures, equipment, inventory and other property (except for intangible personal property, such as patents and trademarks) owned by Tenant which may be placed in the Premises or affixed or attached thereto and also upon all proceeds of any insurance which may be issued on account of damage to any such property. All exemption laws are hereby waived in favor of said lien and security interest benefiting Landlord. This lien and security interest is given in addition to any statutory lien benefiting Landlord and shall be cumulative thereto or alternative thereto as elected by Landlord at any time. Landlord shall, in addition to all of its rights under the Lease, also have all of the rights and remedies of a secured party under the Uniform Commercial Code of the state in which the Premises are located.

                    MERCANTILE-SAFE DEPOSIT & TRUST COMPANY

                                 REVOLVING NOTE
                                  (COMMERCIAL)

$15,000,000.00                                                 November 25, 1996

         In this Note, the Bank named above is hereinafter referred to as
"Bank."  The Undersigned means each and all who sign below, whether one or more
than one, and their obligations hereunder are joint and several.

         On or before November 25, 1997, the Undersigned promised to pay to the
order of Bank $15,000,000.00 (Fifteen Million U.S. Dollars), or so much thereof
as Bank in its discretion has advanced or readvanced and is outstanding
hereunder (being herein called "Principal Sum"), with interest as stated below
on the Principal Sum.  Bank has established a revolving line of credit for
Undersigned from which Undersigned, subject to Bank's consent, may obtain one
more loans from time to time, with the aggregate unpaid Principal Sum of such
loans actually advanced and remaining unpaid not to exceed the face amount of
this Note.  Advances and readvances hereunder remaining unpaid from time to
time shall bear interest each day until paid at a daily periodic rate
corresponding to an annual percentage rate equal to -0- percent above
Mercantile's Prime Rate (being herein called the "Index").  The daily periodic
interest rate will increase or decrease as the Index increases or decreases. 
Where Bank's Prime Rate is used as the Index, the "Prime Rate" is one of
several rates set by Bank from time to time as an interest rate base for
borrowings.  Bank may lend at rates above and below the Prime Rate.  Interest
shall be due and payable monthly.

         If Maker fails to pay any amount within 15 days after the date on
which it is due, Maker agrees to pay a late charge of the greater of $2 or 5%
of the delinquent amount.  All payments will be applied in any manner we choose
except as otherwise required by applicable law.  Generally, payments are
applied first to interest due; second to principal due, third to late charges;
fourth to any remaining interest and finally to the remaining principal.

         Maker covenants to provide Bank such financial information as Bank may
request from time to time and authorizes Bank to make all inquiries it deems
necessary to verify the accuracy of the information provided, to protect and
maintain its assets in good condition and repair, free of all liens and
encumbrances, to keep its assets insured against loss by fire, theft and other
casualties as required by Bank in such amounts and by carriers satisfactory to
Bank, not to dispose of any assets except in the ordinary course of business,
and to pay all taxes and assessments when due.

         Advances and readvances hereunder may be prepaid in whole or in part.
The fact that the balance hereunder may be reduced to zero from time to time
will not affect the continuing validity of this Note, and the balance may be
increased to the face amount of the Note after such reductions to zero.  Bank
in its discretion may make an advance which causes the principal balance to
exceed the face amount of the Note and such excess shall be paid by the
Undersigned upon demand with interest as provided above.

         Each of the following events shall constitute a default hereunder; (a)
the breach of any representation in or the failure of any Obligor (which term
shall include each Maker, endorser, surety and guarantor of any of the
Liabilities) to perform any covenant or agreement under any of the Liabilities
(which term shall include all obligations under this Note, and any renewals,
extensions or modifications thereof, and all other obligations of any kind of
Maker to Bank and to any other party to the extent of Bank's interest therein,
now or hereafter existing, including liabilities to Bank of Maker as a member
of any partnership or other group and whether incurred by Maker as principal or
otherwise); (b) the death of any Obligor; (c) the filing of any petition under
the Federal Bankruptcy  Code or any similar Federal or state statute, by or
against Obligor; (d) an application or the appointment of a receiver for, the
making of a general assignment for the Benefit of Creditors by, or the
insolvency of an Obligor; (e) commencement of any proceeding under any Federal
or state statute or rule providing for the relief of debtors, composition of
creditors, arrangement, reorganization, receivership liquidation or any similar
event by or against any Obligor; (f) the entry of a judgment against any
Obligor; (g) the issuing of any attachment or garnishment, or the filing of any
lien, against any property of any Obligor; (h) the suspension by any Obligor of
the transaction of such Obligor's usual business; (i) the merger or
consolidation of any corporate Obligor with any other corporation or the
transfer, disposition or encumbrance of all or a substantial part of the assets
of any Obligor; (j) if any Obligor misinformed or failed to inform  Bank as to
any matter which the Bank deems material to a Liability; (k) the determination
by an officer of Bank that an adverse change has occurred in the financial
condition of any Obligor from the condition of such Obligor as heretofore most
recently disclosed to Bank by a financial statement or in any other manner.  If
this Note is payable upon demand may be made whether or not an event has
occurred.

         To secure payment of the Liabilities, Bank is hereby granted a lien
and security interest in all property of any Obligor held now or hereafter by
Bank in any capacity and upon the occurrence of any default hereunder Bank
shall have the right , immediately and without further action by it, to set-off
against any of the Liabilities, all such property, and Bank shall be deemed to
have exercised such right of set-off and to have made a charge against such
property immediately upon the
   2
occurrence of such default even though such charge is made or entered
subsequently on the books of Bank.

         A delay by Bank in exercising any right or remedy shall not constitute
a waiver.  A waiver of a default, right or remedy shall not constitute a waiver
of a subsequent default, right or remedy.  A single or partial exercise of a
right or remedy shall not preclude or constitute a waiver of any unexercised
right or remedy.  Bank will not waive a default by accepting partial payment of
any amount due.  All rights and remedies hereunder and under applicable laws
shall be cumulative.  Every obligation of each Obligor is joint and several.
Bank may exercise its rights against Collateral or an Obligor without first
having recourse against any other collateral or Obligor.

         Whenever any Obligor shall be in default hereunder, Bank at its option
(1) may cure the default at Maker's expense; (2) may refuse to make further
advances; (3) may declare any of the Liabilities immediately due and payable;
and (4) may exercise any or all rights and remedies available to it under the
Liabilities and applicable law.

         Maker covenants to pay on demand, with interest until paid in full at
the rate imposed upon principal herein, all expenses incurred by Bank,
including legal fees, to cure any default herein, to enforce any provision of
the Liabilities or to exercise any right or remedy.

         Each Obligor waives presentment, notice of dishonor, protest and all
other demands and notices in connection with any of the Liabilities and with
respect to any collateral and waives any right to trial by jury and further
agrees that the courts of the State of Maryland shall have personal
jurisdiction over it in any legal proceedings with respect to any of the
Liabilities.  Each Obligor without further notice assents to all extensions of
the time of payment of any Liability or any other indulgence or modification of
a Liability, to any substitution, exchange or release of collateral and to the
addition or release of any Obligor, whether or not done for consideration, all
without in any way affecting its obligation.  Bank may unjustifiably and
without reservation of rights impair any Obligor's recourse against another
obligor or collateral.  Except when invalid or unenforceable by statute or
otherwise, each and every Obligor authorizes any attorney designated by Bank to
confess judgment in any Court of Record and authorizes Bank to instruct the
clerk of any Court of Record to confess judgment against such Obligor at any
time after this Note is due by its terms or upon default, for the unpaid
balance of this Note and interest payable thereon, together with court costs
and all other amounts payable to Bank pursuant hereto, including an attorney's
fees of 15% of the total sum due, provided, however, that any lien arising from
such confession of judgment shall not without further proceedings, apply or
attach to any real property as described in section 12-401(i) of the Maryland
Secondary Mortgage Loan Law as the same may be amended from time to time unless
this is a loan to a corporation or a commercial loan in excess of $75,000.00.

         The Undersigned hereby authorizes the Bank to accept instructions by
telephone from any of the Undersigned or a duly authorized representative of
the Undersigned to make advances or receive a repayment hereunder.  All
advances made hereunder shall be credited to the Undersigned's deposit account
with the Bank.  The Undersigned agrees that the actual crediting of the sum of
money so borrowed to the Undersigned's deposit account shall constitute
conclusive evidence that the advance was made, and the failure of the Bank to
forward to the Undersigned an advice of credit shall not affect the obligation
of the Borrower to repay such advance.

         This Note contains the full agreement of the parties and may be
modified only by a writing executed by the party to be charged.

         This Note is executed and delivered the date above written as an
instrument under Seal, specifically intending it to be a specialty and shall be
governed by the Laws of the State of Maryland.
