ITEM 1. BUSINESS COMPANY - ------------------------------------------------------------------------------- CIENA Corporation (the "Company" or "CIENA") was incorporated in Delaware in November 1992. The Company completed its initial public offering on February 7, 1997 and a secondary offering on July 2, 1997. CIENA's principal executive offices are located at 1201 Winterson Road, Linthicum, Maryland 21090. Its telephone number is (410) 865-8500. GENERAL - ------------------------------------------------------------------------------- OVERVIEW CIENA is a leader in the rapidly growing intelligent optical networking equipment market. We offer a comprehensive portfolio of products for communications service providers worldwide. Our customers include long-distance carriers, competitive and incumbent local exchange carriers, Internet service providers, wireless and wholesale carriers. CIENA offers optical transport and intelligent optical switching systems that enable service providers to provision, manage and deliver high-bandwidth services to their customers. We have pursued a strategy to develop and leverage the power of disruptive technologies to change the fundamental economics of building carrier-class tele- and data-communications networks, thereby providing our customers with a competitive advantage. CIENA's intelligent optical networking products are designed to enable carriers to deliver any time, any size, any priority bandwidth to their customers. The Company had revenues of $858.8 million for its fiscal year ended October 31, 2000, an increase of approximately 78% when compared with fiscal 1999 revenues of $482.1 million. Net income for fiscal 2000 was $81.4 million. This compares with a net loss of $3.9 million for fiscal year 1999. For the fiscal year ended October 31, 2000, the Company recorded revenue from sales of intelligent optical networking equipment to a total of thirty-two service provider customers. This represents an increase of more than 18% over 1999's customer base of twenty-seven. During fiscal 2000, three customers each represented more than 10 percent of CIENA's total revenues. Historically, the significant majority of CIENA's revenues have come from the sale of products in a single product category: long-distance optical transport equipment. CIENA believes it is one of the worldwide market leaders in field deployment of open-architecture long-distance optical transport equipment utilizing dense wavelength division multiplexing, or DWDM, technology. The majority of CIENA's fiscal 2000 revenue was derived from sales of its long distance optical transport products, including MultiWave CoreStream(TM) and MultiWave Sentry 4000(TM). During the fiscal year 2000, CIENA also recognized revenue from the sale of seven optical networking products including sales of its metropolitan optical transport product, MutliWave(R) Metro and its intelligent optical core switch, MultiWave CoreDirector(TM). Our research and development efforts as well as potential future acquisition and partnership activities are targeted at capitalizing on our installed base of carrier customers and leveraging our position as a leader in the rapidly growing optical networking market. 2

3 INDUSTRY BACKGROUND - -------------------------------------------------------------------------------- The world's tele- and data-communications infrastructure is formed by fiber optic networks owned and operated by service providers. In recent years, the combination of several factors, including global deregulation which fueled competition among service providers and increased bandwidth demand resulting from the proliferation of the Internet and the emergence of electronic commerce, gave rise to the increased deployment of communications equipment utilizing dense wavelength division multiplexing technology ("DWDM"). DWDM replaces the single beam of light that traverses fiberoptic cable in legacy networks with multiple colors of light, each of which is capable of carrying tens of thousands of voice conversations or data transmissions. Prior to the emergence of DWDM, service providers could increase network capacity either by adding new physical fibers to their network or by increasing the rate of transmission through the fiber. In many cases DWDM has proven to be more cost efficient than physically deploying new fibers and it has enabled the delivery of significantly more traffic by service providers. DWDM adds "virtual lanes to the information highway" as opposed to simply "raising the speed limit within the existing lane." The widespread adoption of DWDM enabled carriers to efficiently and economically expand network capacity, or bandwidth, while reducing bandwidth costs. CIENA believes that the application of products using DWDM has led to a dramatic decline in service providers' capital cost per bit from 1995 to present, thereby enabling pricing competition between carriers and significant bandwidth price declines of up to 80% in some US regions. Network Scalability Challenges For the past several years DWDM has been implemented by carriers to increase capacity between discrete points in their long-distance networks. To construct a network using DWDM equipment as its backbone, a carrier must interconnect the point-to-point high-capacity links and manage all traffic flowing through them. An important element enabling this interconnection in traditional architectures has been the SONET/SDH add/drop multiplexer, or ADM. In most network architectures, a SONET ADM is used to transmit the information-carrying signal for each DWDM optical channel. A second ADM then is used to receive the information-carrying signal from each DWDM optical channel. As a result, every time an additional optical channel is deployed, two additional SONET ADMs must be purchased, installed and maintained -- one for each end of the traffic-carrying route. For example, in order to transmit/receive the traffic from a DWDM optical transport system with 96 channels of DWDM, a service provider would require a total of 192 SONET ADMs. Though DWDM gave carriers the ability to solve the bandwidth problem in the core of their networks, the technology created operational and scalability challenges for carriers. Historically this method has been the only way available to service providers to scale their networks. Unfortunately, this approach creates upwardly spiraling costs. In addition to the capital equipment costs associated with the equipment, each SONET ADM uses valuable central office space and power. Furthermore, as the number of DWDM channels and links increases, the carrier's management of the network grows more complex, making manual service provisioning and network operation more difficult and costly. Escalating Operational Costs In addition to the problems inherent in scaling traditional network architectures, carriers are challenged to scale their operating staff as quickly as they can grow their networks. According to information filed by carriers with the United States Securities and Exchange Commission, many service providers are spending more on operating, growing, and managing their networks than they are on capital expenditures. In some cases, service providers are spending two to four dollars on network operations and support expenses for every dollar spent on capital equipment. In addition, in many cases, network operations and support expenses are increasing at a significantly faster rate than revenues. 3

4 CIENA'S SOLUTIONS - ------------------------------------------------------------------------------- CIENA's intelligent optical networking equipment was designed to enable service providers to transition from inefficient, legacy, voice-centric networks to more efficient data-optimized, intelligent optical networks. CIENA's systems address both the network scalability challenges and the escalating operational costs faced by service providers. - CIENA leverages its expertise in optics, software, systems and Application Specific Integrated Circuits, or ASICs, to develop innovative products designed to dramatically lower the cost of constructing service provider networks. - CIENA's intelligent optical networking equipment is designed to replace multiple legacy network elements with fewer, more intelligent network elements, thereby simplifying the network and lowering carriers' capital and operations costs. - With the bandwidth availability enabled by CIENA's optical transport equipment, service providers should be able to ramp their network bandwidth with growing Internet demand. - CIENA's intelligent optical networking equipment is designed to lower ongoing network operating costs by enabling carriers that utilize our equipment to more efficiently manage network traffic. - CIENA's intelligent optical networking equipment also is designed to enable carriers to shorten the time it takes to provision services, in some cases from months to real-time, thereby accelerating the generation of revenue. - In addition to capital and operational cost savings, CIENA's intelligent optical networking equipment and recently introduced network management software is designed to enable new, revenue-generating and service-differentiating optical services. Our optical networking product portfolio is targeted at the critical areas of service provider networks: long-distance optical transport, short-distance optical transport and intelligent core switching. - Optical Transport. CIENA's long-distance optical transport products, MultiWave CoreStream(TM), MultiWave Sentry(TM) , MultiWave 1600, and our short distance products, MultiWave Metro(TM), Metro One(TM) and MultiWave Firefly,(TM) utilize DWDM technology and should enable carriers to cost effectively add critical network bandwidth when and where they need it. As a result, service providers should be better able to scale their networks to meet demand. - Intelligent Optical Core Switching. Our intelligent optical core switches, MultiWave CoreDirector(TM), and MultiWave CoreDirector CI(TM) enable carriers to manage the bandwidth created with optical transport products. CoreDirector and CoreDirector CI help carriers' solve both the issues of network scalability and escalating operating costs by incorporating the functionality of multiple network elements into single elements with previously unavailable switching capabilities and management. - Network Management. ON-Center, CIENA's recently introduced fully integrated family of software-based tools for comprehensive element, network and service layer management, is designed to enable accelerated deployment of new, differentiating optical services. ON-Center should also reduce network operating and management costs. CIENA calls the network architecture created by these products "CIENA LightWorks." The components of CIENA's LightWorks can be sold together as a complete network solution or separately as best-of-breed solutions. CIENA's LightWorks architecture is designed to dramatically simplify a carrier's network by reducing the number of network elements. We believe this network simplification will lead to lower capital equipment cost and lower operating cost. 4

5 STRATEGY - ------------------------------------------------------------------------------- CIENA's strategy is to maintain and build upon its market leadership in the deployment of intelligent optical networking systems and to leverage the Company's technologies in order to provide solutions for both voice and data communications-based network architectures. The Company believes that the technological, operational and cost benefits of the Company's optical networking solutions create competitive advantages for service providers worldwide. We believe our solutions will become increasingly important as these service providers are being pressed by their customers to deliver services to address the dramatic growth in Internet and other data communications traffic. CIENA's strategy includes the following: - - EXPAND OUR BASE OF CUSTOMERS USING OUR OPTICAL NETWORKING SOLUTIONS. We believe that achieving early widespread operational deployment of our systems in a particular carrier's network will provide CIENA significant competitive advantages with respect to additional optical networking deployments and will enhance our marketing to other carriers as a field-proven supplier. While continuing to aggressively serve our existing customers, we intend to actively pursue additional optical networking deployment opportunities among fiber optic carriers in domestic and foreign long distance, interoffice and local exchange markets. - - EXPAND SALES AND MARKETING EFFORTS. The nature of the target customer base for all our product lines requires a focused sales effort on a customer-by-customer basis. We will continue to increase our sales and marketing efforts aimed at the worldwide market of service providers. CIENA increased the number of revenue generating optical networking customers from twenty-seven during 1999 to thirty-two in 2000. In addition, CIENA has a significant international presence, particularly in Europe. Market analyst RHK estimates that CIENA holds the leading share of the European optical networking market at 37%. Revenues from international customers represented 33.0% of CIENA's total revenues in fiscal 2000. CIENA plans to continue to strengthen its marketing programs and to increase its domestic and international presence through both direct sales and distributor relationships. - - CONTINUE TO EMPHASIZE TECHNICAL SUPPORT AND CUSTOMER SERVICE. CIENA markets technically advanced systems to sophisticated customers. The nature of CIENA's systems and market require a high level of technical support and customer service. We believe we have a good reputation for our technical support and customer service and we intend to emphasize our global service and support excellence and capabilities as differentiating factors in our efforts to maintain and enhance our market position. CIENA offers complete engineering, furnishing and installation services in addition to full-time customer support from strategic locations worldwide. - - CONTINUE TO ENHANCE WORLD CLASS MANUFACTURING CAPABILITY. CIENA's optical networking systems play a critical role in our customers' networks. Quality assurance and manufacturing excellence are necessary for CIENA to achieve success. CIENA believes it has developed a world class optical manufacturing capability and this capability provides CIENA with a significant competitive advantage. CIENA achieved ISO 9001 certification in July 1997 in further support of this element of its strategy. CIENA expects to continue to invest in both the capital and the human resources necessary to maintain and leverage this advantage. In addition, CIENA expects to utilize this expertise to leverage our manufacturing capability with contract manufacturers. - - LEVERAGE THE COMPANY'S HIGH BANDWIDTH TECHNOLOGIES AND KNOW-HOW. We believe the overall growth in demand for bandwidth and the need for intelligent high bandwidth services in telecommunications networks will lead to transmission bottlenecks in other segments of the networks where the application of optical technologies and other high bandwidth enabling technologies may provide solutions, either within existing network architectures, or as part of the design and development of alternative data communications-based network architectures. CIENA expects to leverage the core competencies it has developed in the design, development and manufacturing of its optical transport and intelligent optical switching product lines by pursuing new product development efforts, and strategic alliances or acquisitions, to address these expected opportunities. CIENA intends to move aggressively to maintain leadership in the design and development of intelligent optical networking equipment and software which will both respond to customer needs and help customers move toward newer, higher capacity, more cost-efficient network designs for the future. 5

NEW OPTICAL SERVICES - -------------------------------------------------------------------------------- In addition to offering significant capital equipment and operational cost savings, CIENA's intelligent optical networking equipment is designed to enable its customers to offer new, revenue generating optical layer services. CIENA's LightWorks Toolkit(TM) is designed to allow carriers to offer dynamic high-bandwidth services and handle real-time service provisioning and prioritization. By mixing and matching CIENA's ToolKit tools, carriers will be able to offer customized services and further differentiate themselves from their competition. Tools in the LightWorks ToolKit will ultimately include: Service Description - ------- ----------- Optical Priority - Optical Priority Provisioning is designed to Provisioning allow carriers to turn-up optical services in real time, and to specify priority levels for further differentiation of optical services. For instance, a carrier may elect to offer multiple levels of optical bandwidth, ranging from "premium" to "best-effort" service, with each level of service being priced and delivered differently. Optical Priority Provisioning is designed to help carriers more easily meet service level agreements by assigning and 7

8 adjusting traffic priorities in real time, potentially allowing carriers to unlock more revenue from data services. - Optical Priority Provisioning should simplify the delivery of differentiated optical services by providing access to service templates of predefined restoration priorities, preemptability, and linear, ring and mesh protection schemes. Using these simplified templates, service provisioners should be able to deliver optical services, at any service level, in just a few clicks of a mouse. Flexible Concatenation - In legacy networks, bandwidth demand is arbitrarily shoehorned into SONET/SDH-sized transport containers where the size of the container is fixed. For example, if a customer requires OC-15 service, the customer must purchase OC-48 service, even though only a fraction of the 48 time slots in the transport container will be filled with bits. In this scenario, the customer is paying for bandwidth it is not using and the carrier is losing valuable network bandwidth. CIENA is using a combination of silicon and software to redefine how carriers access and deliver bandwidth. - When available, Flexible Concatenation will allow carriers to access all time slots within the SONET/SDH frame - even when those frames are fractionally filled. That means carriers will be able to create true OC-"N" services in which "N" can be any number between 1 and 48 and in the future will be 192 and eventually 768 instead of the current restrictions of SONET which sets fixed sizes on transport containers. Flexible concatentation is designed to enable carriers to maximize their network bandwidth and deliver customer-specific service. Rate Adaptive Gigabit - CIENA's Rate-Adaptive Gigabit Ethernet Ethernet technology uses software and ASICs to enable service providers to sell "any-size" Gigabit Ethernet services in increments of 50Mbps (STS-1) up to 1.25Gbps. - When available, service providers will be able to use Rate Adaptive Gigabit Ethernet to create a wide range of customized optical service options for end-users and deliver those services over more efficient access and core networks that leverage the economies of Gigabit Ethernet transmission. VSR Optics - For increased profitability, carriers must continually drop their cost per bit. However, to stay competitive, carriers must continue to increase the value of their services. VSR (Very Short Reach) Optics are designed to provide lower-cost, high-capacity connections between Internet and optical networking systems within a service provider's central office. VSR Optics leverage Vertical Cavity Surface Emitting Laser (VCSEL) technology and Gigabit Ethernet standards to make variable-rate optical services possible and economical - a valuable service for unpredictable bandwidth demands. When available, CIENA will apply this data rate-scalable technology to 10Gbps network connections. Transparent Service - As opposed to traditional SONET/SDH Multiplexing multiplexing, CIENA's "transparent" multiplexing is designed to enable optical services to be delivered without compromising the SONET/SDH overheads of individual tributaries that make up the aggregate signal. Enabling multiple signals to be transparently multiplexed, transported and demultiplexed means signals are delivered as if they were connected directly to the destination equipment by their own unique wavelength, maintaining the customers' signal security and integrity. When available, Transparent Service Multiplexing (TSM) should be ideal for delivering IP traffic, wavelength services and other new optical services that CIENA's Toolkit enables. With TSM, each end device appears to communicate over its own unique wavelength while actually being economically consolidated with other signals. 8

9 Wavelength Binding - With unprecedented traffic growth and changing traffic demands, Internet-centric carriers are looking for ways to better match the changes in IP router traffic demands with the provisioned bandwidth capacities available within their networks. To meet this need, CIENA is developing Wavelength Binding. - Wavelength Binding will leverage intellectual property to enable a device of any speed to be connected to a network operating at a lower speed by building "virtual channels" of multiple wavelengths bound together in a single, very high capacity bitstream. As a result, when Wavelength binding is available CIENA's customers will be able to deliver 40 gigabits per second without changing their transport infrastructure. Wavelength Binding will also give carriers previously unavailable network flexibility by enabling them to bundle and unbundle wavelengths as network capacity demands change. PRODUCT DEVELOPMENT - ------------------------------------------------------------------------------- We believe the overall growth in utilization of fiber optic telecommunications networks will lead to transmission bottlenecks in other segments of the networks where the application of optical networking technologies may provide solutions. We also believe there may be opportunities for us to develop products and technologies complementary to existing optical networking technologies which may broaden our ability to provide, facilitate and/or interconnect with high bandwidth solutions offered throughout fiber optic networks. CIENA intends to focus its product development efforts and possibly pursue strategic alliances or acquisitions to address expected opportunities in these areas. CUSTOMERS - ------------------------------------------------------------------------------- CIENA has announced publicly relationships with the following thirty-five customers: Domestic International -------- ------------- 1. Alltel Corporation 1. Cable & Wireless Communications Services Limited, UK 2. Bell South Telecommunications, Inc 2. CompleTel SAS, France 3. Broadwing Communications Services, 3.

10 CUSTOMERS BY CATEGORY INTEREXCHANGE CARRIERS (IXCS) The initial deployments of CIENA's bandwidth enhancing optical transport equipment occurred in the core of the U.S. long-distance network with the interexchange carriers or IXCs. IXCs provide connections between local exchanges in different geographic areas. In recent years, incumbent IXCs such as Sprint, WorldCom and AT&T have seen increased competition from emerging long-distance carriers such as Qwest Communications, Global Crossing, Broadwing Communications Services, Inc., and Level 3 Communications. We expect that continued competition in long-distance call rates, as well as the carriers' desire for market and service differentiation, will continue to drive demand for the increased capacity and features offered by CIENA's optical networking equipment. COMPETITIVE LOCAL EXCHANGE CARRIERS (CLECS) Deregulation has fueled the growth of U.S. competitive local exchange carriers or CLECs. CIENA believes that in the short-term, CLECs could benefit from the hesitancy of incumbent local exchange carriers, such as the Regional Bell Operation Companies ("RBOCs"), to open their local markets to competitors, and that these CLECs are likely to move aggressively to capitalize on opportunities in the local area. CIENA recognized revenues from CLEC customers in fiscal 2000 and expects that tactical CLEC applications for its long-haul products, as well as the short-distance products, will be well-suited to CLEC network applications. INTERNATIONAL COMPETITIVE CARRIERS New competitive carriers are emerging as a result of deregulation in the international telecommunications markets as well. CIENA has concentrated its sales efforts on these emerging carriers as opposed to the traditional carriers or PTTs. During Fiscal 2000, CIENA increased its announced international customer base from fourteen to eighteen customers. In many cases, these new competitive carriers do not have the installed fiber base of the larger carriers and therefore are in need of the scalable bandwidth CIENA's optical transport systems offer. In addition, because of the economies and flexibility afforded by the application of DWDM technology, CIENA's equipment is being used on several new builds where the service provider is physically constructing the network. CIENA expects that in the near-term, the majority of its international revenue will come from these smaller, more aggressive competitive carriers, and will continue to concentrate its sales efforts accordingly. NON-TRADITIONAL TELECOMMUNICATION SERVICE PROVIDERS The growth of the Internet has produced traffic growth substantial enough to attract new, non-traditional telecommunication service providers to compete in this market as well. Both domestically and internationally, companies with rights-of-way, such as utility companies, cable TV providers, and railroads are capitalizing on their "network" (whether a pipeline, a railroad, or a highway), and in some cases, are laying optical fiber and constructing telecommunications networks along those rights-of-way. The transmission capabilities of CIENA's optical networking equipment enables these new carriers to provide competitive services while purchasing and laying a minimal amount of fiber optic cable. INCUMBENT LOCAL EXCHANGE CARRIERS Incumbent local exchange carriers, such as the RBOCs, are very active in interoffice and local exchange markets and, under the Telecommunications Act of 1996, RBOCs are eligible to enter the long distance market once they have met certain requirements for opening their local markets to competition. CIENA believes that over time the RBOCs will continue to gain approval to offer long distance services, 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. Regardless of the timing of any such move, CIENA believes there are opportunities for in-region deployment of CIENA's long distance and metropolitan optical transport products at certain RBOCs. 10

11 MARKETING AND DISTRIBUTION - ------------------------------------------------------------------------------- CIENA's intelligent optical networking systems require substantial investment, and our target customers in the fiber optic 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 optical networking systems with existing transmission equipment. The convergence of these factors leads to a very long sales cycle for optical networking equipment, 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. See Item 7. "Management's Discussion and Analysis of Financial Conditions and Results of Operations - Risk Factors." CIENA has organized its resources for the separate but coordinated approach to United States 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, CIENA pursues prospective customers through direct sales efforts, as well as through distributors, independent marketing representatives and independent sales consultants. CIENA established CIENA Communications, Inc. as a wholly-owned subsidiary to coordinate worldwide sales, marketing, customer service and installation support functions. CIENA Communications Japan, Ltd. is a wholly-owned subsidiary established to coordinate sales, marketing and customer service efforts in Japan, the Pacific Rim and other Asian areas. CIENA established CIENA Limited as a wholly-owned subsidiary in the U.K. to coordinate European, and Middle Eastern sales, marketing, customer service and installation support functions. Through its subsidiaries, CIENA has established offices in the U.S., Europe and Latin America, including offices in the U.K., Germany, France, Spain, Mexico and Brazil. CIENA has distributor or marketing representative arrangements, including agreements with agents in Italy, the Republic of Korea, Japan, Venezuela, Columbia and Chile. In support of its worldwide selling efforts, CIENA conducts marketing communications programs intended to position and promote its products within the telecommunications industry. Marketing personnel also coordinate our participation in trade shows and conduct media relations activities with trade and general business publications. MANUFACTURING - ------------------------------------------------------------------------------- CIENA conducts most of the optical assembly, final assembly and final component, module and system test functions for its optical transport products at its manufacturing facilities in Maryland. It also manufactures the in-fiber Bragg gratings used in its optical transport product lines. We expect the majority of the manufacturing associated with our MultiWave CoreDirector and CoreDirector CI products will be performed by third-party manufacturers, with only final system test and assembly performed by CIENA. We also rely on third party manufacturers to manufacture some of our components for our products and continue to evaluate whether additional portions of our manufacturing can be done on a reliable and cost-effective basis by third party manufacturers. CIENA believes that portions of its manufacturing technologies and processes represent a key competitive advantage. Accordingly, we have invested significantly in automated production capabilities and manufacturing process improvements and expect to further enhance our manufacturing process with additional production process control systems. Certain critical manufacturing functions require a highly skilled work force, and CIENA puts significant efforts into training and maintaining the quality of its manufacturing personnel and in maintaining its proprietary information in this area. CIENA's optical transport product lines utilize hundreds of individual 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. CIENA works closely with its strategic component suppliers to pursue new component technologies that could either reduce cost or enhance the performance of our products. 11

12 COMPETITION - ------------------------------------------------------------------------------- Competition in the telecommunications equipment industry is intense, particularly in that portion of the industry focused to delivering higher bandwidth and more cost effective services throughout the telecommunications network. CIENA believes that its position as a leading supplier of open architecture optical networking equipment and the field-tested design and performance of its optical transport products give it a competitive advantage and expects to leverage that advantage in bringing its core switching products to market. However, competition has been and will continue to be very intense. See Item 7. "Management's Discussion and Analysis of Financial Conditions and Results of Operations-Risk Factors." The competition faced by CIENA 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 CIENA. Included among CIENA's competitors are Lucent Technologies Inc., ("Lucent"), Northern Telecom Inc. ("Nortel"), Alcatel Alsthom Group ("Alcatel"), NEC Corporation ("NEC"), Cisco, by virtue of its acquisition of Pirelli SpA, Siemens AG ("Siemens"), Fujitsu Group ("Fujitsu"), Hitachi Ltd. ("Hitachi") and Telefon AB LM Ericsson ("Ericsson"). CIENA also believes that several new companies, such as ONI Systems, Sycamore Networks, Corvis Systems, and Tellium, Inc., will attempt to break into the rapidly emerging optical networking market. Each of CIENA's major competitors is believed to be in various stages of development, introduction or deployment of products directly competitive with CIENA's optical transport, core switching and service delivery systems. In addition to optical networking equipment suppliers, traditional TDM-based transmission equipment suppliers compete with CIENA in the market for transmission capacity. Lucent, Alcatel, Nortel, Fujitsu, Hitachi and NEC are already providers of a full complement of such transmission equipment. These and other competitors have introduced or are expected to introduce equipment that will offer 10 Gb/s transmission capability. PATENTS AND OTHER INTELLECTUAL PROPERTY RIGHTS CIENA has licensed intellectual property from third parties, including certain key enabling technologies with respect to the production of in-fiber Bragg gratings, utilized publicly available technology associated with Erbium-doped fiber amplifiers, and applied its design, engineering and manufacturing skills to develop its optical transport systems. These licenses expire when the last of the licensed patents expires or is abandoned. CIENA also licenses from third parties certain software components for its network management products. These licenses are perpetual but will generally terminate after an uncured breach of the agreement by CIENA. We have registered trademarks for CIENA, WaveWatcher, MODULE SCOPE, CIENA Optical Communications, Multiwave, and Multiwave Sentry. CIENA also relies on contractual rights, trade secrets and copyrights to establish and protect its proprietary rights in its products. CIENA intends to enforce vigorously its intellectual property rights if infringement or misappropriation occurs. CIENA'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 CIENA. These agreements acknowledge CIENA's exclusive ownership of all intellectual property developed by the individual during the course of his or her work with CIENA, and require that all proprietary information disclosed to the individual will remain confidential. CIENA's employees generally also sign agreements not to compete with CIENA for a period of twelve months following any termination of employment. As of November 2000, CIENA had received fifty-eight (58) United States patents, and had one hundred sixteen (116) pending U.S. patent applications. We also have a number of foreign patents and patent applications. Of the United States patents that have been issued to CIENA, the earliest any will expire is 2012. Pursuant to an agreement between CIENA and General Instrument Corporation dated March 10, 1997, CIENA is a co-owner with General Instrument Corporation of a portfolio of 27 United States and foreign patents relating to optical communications, primarily for video-on-demand applications. See Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations-Risk Factors." 12

20 ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS The following discussion and analysis should be read in conjunction with "Selected Consolidated Financial Data" and the Company's consolidated financial statements and notes thereto included elsewhere in this report on Form 10-K. OVERVIEW CIENA is a leader in the rapidly growing intelligent optical networking equipment market. We offer a comprehensive portfolio of products for communications service providers worldwide. Our customers include long-distance carriers, competitive and incumbent local exchange carriers, Internet service providers, wireless and wholesale carriers. CIENA offers optical transport and intelligent optical switching systems that enable service providers to provision, manage and deliver high-bandwidth services to their customers. We have pursued a strategy to develop and leverage the power of disruptive technologies to change the fundamental economics of building carrier-class tele- and data-communications networks, thereby providing our customers with a competitive advantage. CIENA's intelligent optical networking products are designed to enable carriers to deliver any time, any size, any priority bandwidth to their customers. CIENA's LightWorks is an optical networking architecture designed to change the fundamental economics of building service provider networks. LightWorks focuses on the three critical areas of optical networking: long-distance optical transport, short-distance optical transport and intelligent core switching. The products in CIENA's LightWorks combine the functionality of several current network elements into a single network element, thereby lowering the capital equipment requirements of a service provider and simplifying the network, in order to reduce a carrier's network operating costs. The products of CIENA's LightWorks architecture can be sold together as a complete network solution or separately as best-of-breed solutions. Products include four generations of long distance optical transport systems: MultiWave 1600, MultiWave Sentry 1600, MultiWave Sentry 4000, and MultiWave CoreStream. LightWorks also includes CIENA's short distance optical transport products: MultiWave Firefly, MultiWave Metro, and MultiWave Metro One. CIENA's LightWorks architecture also includes its MultiWave CoreDirector family of optical core switching products. The recently introduced MultiWave CoreDirector is an intelligent optical core switch that allows carriers to deliver a full range of transport services, without costly SONET/SDH (synchronous optical networks/synchronous digital hierarchy) multiplexers and with more flexibility than "wavelength only" devices. The first release of the MultiWave CoreDirector became available during the third fiscal quarter ended July 31, 2000. In November 1999, CIENA announced it was pursuing enhancements to its MultiWave CoreStream product that will enable the system to offer the optimal combination of longer reach transport functionality and channel count to further lower network costs for service providers. Using forward error correction (FEC), nonlinearity management, and dispersion mapping technologies, plus embedded system intelligence, MultiWave CoreStream ultimately will be able to support optical spans of up to 5,000 kilometers without additional optical-to-electrical signal regeneration. We expect to begin customer shipments of the longer reach features of this product in the first quarter of fiscal 2001. See "Risk Factors". During January 2000, CIENA announced the LightWorks Toolkit for Optical Services, a series of new optics-, silicon- and software-based service enablers. CIENA's LightWorks Toolkit is designed to assist carriers with the transition from static service provisioning to real-time, on demand bandwidth delivery; from bandwidths limited by traditional SONET/SDH to optical bandwidth of any size; and from a single wavelength quality of service to a range of service qualities that can be dynamically configured and monitored. These service-enabling tools began to be integrated into CIENA's LightWorks products during the second half of calendar 2000. See "Risk Factors". During May 2000, CIENA announced the introduction of its newest intelligent optical core switching product, MultiWave CoreDirector CI, an entry version of CIENA's market-leading MultiWave CoreDirector switch. MultiWave CoreDirector CI is designed to offer network operators all the intelligence, real-time provisioning, dynamic network protection, and comprehensive network management capabilities of MultiWave CoreDirector, but optimized for smaller central offices predominant in regional and metropolitan portions of service provider networks. The initial release of MultiWave CoreDirector CI is expected in limited availability for customer trials during the first quarter of calendar 2001. See "Risk Factors". 20

21 During May 2000, CIENA also announced the launch of its LightWorks ON-Center(TM) Management Suite, a new fully integrated family of software-based tools for comprehensive element, network and service layer management across service provider networks. ON-Center is designed to enable accelerated deployment of new, differentiating optical services, reduced network operating and management costs, and innovative customer service solutions. The ON-Center management suite is designed to help service providers use the built-in networking intelligence of CIENA's LightWorks Toolkit for Optical Services and network architecture to enable real-time service deployment, dynamic service level agreement (SLA) management, multi-vendor optical service monitoring, full Fault, Configuration, Accounting, Performance and Security (FCAPS) management across CIENA systems, and Web-based customer service awareness tools. The initial release of ON-Center became available during October 2000. During August 2000, CIENA announced that it had added Rate-Adaptive Gigabit Ethernet technology to the LightWorks Toolkit for Optical Services. CIENA's Rate-Adaptive Gigabit Ethernet technology uses software and ASICs to enable service providers to sell "any-size" Gigabit Ethernet services in increments of 50 Mbps(STS-1), up to 1.25 Gbps. The service rate is adaptive to end-users' needs, allowing service providers to tailor pricing to a finer granularity of data rates. Additionally, the technology enables providers to transport fractional Gigabit Ethernet traffic from up to 10 different customers over a single 2.5 GPS wavelength. As a result, service providers can create a wide range of customized optical service options for end-users and deliver those services over more efficient access and core networks that leverage the economies of Gigabit Ethernet transmission. Rate-Adaptive Gigabit Ethernet technology is expected to be available for customer trails on CIENA's MultiWave Metro systems in the first half of calendar 2001. CIENA has increased the number of revenue generating optical networking equipment customers from a total of twenty-seven customers during fiscal 1999 to thirty-two customers for fiscal 2000. We intend to preserve and enhance our market leadership and eventually build on our installed base with new and additional products. CIENA believes that its product and service quality, manufacturing experience, and proven track record of delivery will enable it to endure competitive pricing pressure while concentrating on efforts to reduce product costs and maximize production efficiencies. See "Risk Factors". As of October 31, 2000, the Company and its subsidiaries employed approximately 2,775 persons, which was an increase of 847 persons over the approximate 1,928 employed on October 31, 1999. RESULTS OF OPERATIONS FISCAL YEARS ENDED 2000, 1999 AND 1998 REVENUE. The Company recognized $858.8 million, $482.1 million and $508.1 million in revenue for the fiscal years ended October 31, 2000, 1999 and 1998, respectively. The approximate $376.7 million or 78.1% increase in revenue from fiscal 1999 to fiscal 2000 was due primarily to an increase in product shipments across all product lines. The approximate $26.0 million or 5.1% decrease in revenue from fiscal 1998 to fiscal 1999 was largely the result of reduced selling prices. CIENA recognized revenues from a total of thirty-two, twenty-seven, and fourteen optical equipment customers during fiscal 2000, 1999, and 1998, respectively. During fiscal year 2000, Sprint, Qwest Communications and GTS Network Ltd. each accounted for at least 10% or more of CIENA's revenue and all three combined accounted for 60.9% of the Company's fiscal 2000 revenue. During fiscal year 1999 Sprint, WorldCom, and GTS Network Ltd., each accounted for at least 10% or more of CIENA's revenue and all three combined accounted for 46.2% of CIENA's fiscal 1999 revenue. This compares to fiscal 1998 in which Sprint was the only 10% customer and in total accounted for 52.5% of CIENA's fiscal 1998 revenue. Revenue derived from foreign sales accounted for approximately 33.0%, 44.3%, and 23.0% of the Company's total revenues during fiscal 2000, 1999, and 1998, respectively. For fiscal 2000, CIENA's optical network equipment revenues were derived from sales of the MultiWave Sentry 4000, MultiWave CoreStream configured for both 2.5 gigabits per second ("Gbps") and 10.0 Gbps transmission rates, 21

22 MultiWave Sentry 1600, MultiWave Metro, MultiWave 1600, MultiWave CoreDirector, MultiWave Firefly systems and MultiWave MetroOne. During fiscal 1999, the Company recognized revenues from sales of MultiWave Sentry 4000, MultiWave Sentry 1600, MultiWave 1600, MultiWave Metro, MultiWave Firefly, and MultiWave CoreStream systems. During fiscal 1998, the Company recognized revenues from sales of MultiWave Sentry 1600, MultiWave 1600, MultiWave Firefly, and MultiWave Sentry 4000 systems. The revenues for fiscal 2000 improved as compared to fiscal 1999 due to increased sales of MultiWave Sentry 4000, MultiWave CoreStream, MultiWave Sentry 1600, MultiWave Metro, and MultiWave Firefly systems, and also from the introduction of revenues from MultiWave CoreDirector and MultiWave MetroOne systems. The amount of revenue recognized from MultiWave Sentry 1600 and MultiWave 1600 declined in fiscal 1999 as compared to fiscal 1998. This decline in MultiWave Sentry 1600 sales in fiscal 1999 was offset by the introduction of new revenues from the MultiWave CoreStream, and MultiWave Metro products in fiscal 1999. Fiscal 1999 revenues from MultiWave Sentry 4000 and MultiWave Firefly were comparable to the revenues recognized for these products in fiscal 1998. Revenues derived from engineering, furnishing and installation services as a percentage of total revenue were 8.4%, 12.1%, and 9.2% for the fiscal years 2000, 1999, and 1998, respectively. GROSS PROFIT. Cost of goods sold consists of component costs, direct compensation costs, warranty and other contractual obligations, royalties, license fees, inventory obsolescence costs and overhead related to the Company's manufacturing and engineering, furnishing and installation operations. Gross profit was $381.4 million, $182.3 million, and $252.1 million for fiscal years 2000, 1999, and 1998, respectively. Gross margin was 44.4%, 37.8%, and 49.6% for fiscal 2000, 1999, and 1998, respectively. The increase in gross profit from fiscal 1999 to fiscal 2000 was due primarily to lower component costs and improved production efficiencies. The decrease in gross profit from fiscal 1998 to fiscal 1999 was largely attributable to lower selling prices. CIENA's gross margins may be affected by a number of factors, including product mix, continued competitive market pricing, outsourcing of manufacturing, manufacturing volumes and efficiencies, competition for skilled labor, and fluctuations in component costs. Downward pressures on our gross margins may be further impacted by an increased percentage of revenues from EF&I services or additional service requirements. CIENA will continue to concentrate on efforts to reduce product costs and maximize production efficiencies and, if successful in these efforts, may be able to improve gross margins in the future. See "Risk Factors." RESEARCH AND DEVELOPMENT EXPENSES. Research and development expenses were $129.1 million, $104.6 million, and $73.8 million for fiscal 2000, 1999, and 1998, respectively. The approximate $24.4 million or 23.3% increase from fiscal 1999 to 2000 and the approximate $30.9 million or 41.9% increase from fiscal 1998 to 1999 in research and development expenses related to increased staffing levels, purchases of materials used in development of new or enhanced product prototypes, and outside consulting services in support of certain developments and design efforts. During fiscal 2000, 1999, and 1998 research and development expenses were 15.0%, 21.7%, and 14.5% of revenue, respectively. CIENA expects that its research and development expenditures will continue to increase in absolute dollars and perhaps as a percentage of revenue during fiscal 2001 to support the continued development of CIENA's intelligent optical networking products, the exploration of new or complementary technologies, and the pursuit of various cost reduction strategies. CIENA has expensed research and development costs as incurred. SELLING AND MARKETING EXPENSES. Selling and marketing expenses were $90.9 million, $61.6 million, and $47.3 million for fiscal 2000, 1999, and 1998, respectively. The approximate $29.3 million or 47.6% increase from fiscal 1999 to 2000 and the approximate $14.3 million or 30.1% increase from fiscal 1998 to 1999 in selling and marketing expenses was primarily the result of increased staffing levels in the areas of sales, technical assistance and field support, and increases in commissions earned, trade show participation and promotional costs. During fiscal 2000, 1999, and 1998 selling and marketing expenses were 10.6%, 12.8%, and 9.3% of revenue, respectively. The Company anticipates that its selling and marketing expenses may increase in absolute dollars and perhaps as a percentage of revenue during fiscal 2001 as additional personnel are hired and additional offices are opened to allow the Company to pursue new customers and market opportunities. The Company also expects the portion of selling and marketing expenses attributable to technical assistance and field support, specifically in Europe, Latin America, and Asia, will increase as the Company's installed base of operational MultiWave systems increases. GENERAL AND ADMINISTRATIVE EXPENSES. General and administrative expenses were $34.0 million, $22.7 million and $18.5 million for fiscal 2000, 1999, and 1998, respectively. The approximate $11.2 million or 49.5% increase from fiscal year 1999 to 2000 and the approximate $4.3 million or 23.1% increase from fiscal year 1998 to 1999 in 22

23 general and administrative expenses was primarily the result of increased staffing levels and outside consulting services. During fiscal 2000, 1999, and 1998 general and administrative expenses were 4.0%, 4.7%, and 3.6% of revenue, respectively. The Company believes that its general and administrative expenses will increase in absolute dollars and perhaps as a percentage of revenue during fiscal 2001 as a result of the expansion of the Company's administrative staff required to support its expanding operations. SETTLEMENT OF ACCRUED CONTRACT OBLIGATION. The $8.5 million gain from settlement of accrued contract obligation relates to the July 2000 termination of certain accrued contract obligations that CIENA received from iaxis Limited, one of CIENA's European customers. In September 2000, CIENA was informed that an administrative order had been issued by a London court against iaxis Limited. As a result of this order, joint administrators were appointed to manage the business of iaxis Limited while they marketed the business for sale and formulated a reorganization of the company. See "Provision for Doubtful Accounts" below. PURCHASED RESEARCH AND DEVELOPMENT. Purchased research and development costs were $9.5 million for the fiscal year 1998. These costs were for the purchase of technology and related assets associated with the acquisition of Terabit during the second quarter of fiscal 1998. PIRELLI LITIGATION. The Pirelli litigation costs of $30.6 million in fiscal 1998 were attributable to a $30.0 million payment made to Pirelli during the third quarter of 1998 and to additional other legal and related costs incurred in connection with the settlement of this litigation. MERGER RELATED COSTS. The merger costs for fiscal 1999 of approximately $13.0 million were costs related to CIENA's acquisition of Omnia and Lightera. These costs include an $8.1 million non-cash charge for the acceleration of warrants based upon CIENA's common stock price on June 30, 1999 and $4.9 million for fees, legal and accounting services and other costs. The warrants were issued to one of Omnia's potential customers and became exercisable upon the consummation of the merger between CIENA and Omnia. The merger related costs for fiscal 1998 were costs related to the contemplated merger between CIENA and Tellabs. These costs include approximately $1.2 million in Securities and Exchange Commission filing fees and approximately $1.3 million in legal, accounting, and other related expenses. PROVISION FOR DOUBTFUL ACCOUNTS. CIENA performs ongoing credit evaluations of its customers and generally does not require collateral from its customers. CIENA maintains an allowance for potential losses when identified. CIENA's allowance for doubtful accounts as of October 31, 2000 was $29.6 million. Approximately $27.8 million relates to provisions made for doubtful accounts associated with iaxis Limited, one of CIENA's European customers. In September 2000, CIENA was informed that an administrative order had been issued by a London court against iaxis Limited. As a result of this order, joint administrators were appointed to manage the business of iaxis Limited while they marketed the business for sale and formulated a reorganization of the company. In November 2000, CIENA was notified that Dynegy Inc. and its subsidiaries had entered into a proposed agreement to acquire the assets and stock of iaxis Limited from the administrators. As a consequence of the terms of (a) the proposed agreement between the administrators of iaxis Limited, Dynegy and its subsidiaries, and of (b) a related sales agreement between CIENA and Dynegy, CIENA expects to realize approximately $8.9 million of the gross outstanding accounts receivable balance due from iaxis Limited as of October 31, 2000. While the proposed purchase agreement between the administrators of iaxis Limited and Dynegy is subject to certain administrative and judicial approvals, CIENA believes that such approvals will be ultimately obtained and that CIENA will be successful in collecting the net $8.9 million outstanding accounts receivable balance from the customer. However, should such approvals not occur, additional write-offs might be required. OTHER INCOME (EXPENSE), NET. Other income (expense), net, consists of interest income earned on the Company's cash, cash equivalents and marketable debt securities, net of interest expense associated with the Company's debt obligations. Other income (expense), net, was $12.7 million, $13.9 million, and $12.8 million for fiscal 2000, 1999, and 1998, respectively. The decrease in other income (expense) from fiscal 1999 to fiscal 2000 was due to lower balances of cash, cash equivalents and marketable debt securities in fiscal 2000 as compared to fiscal 1999. The increase in companies other income (expense) from fiscal 1998 to fiscal 1999 was primarily the result of the investment of the net proceeds of the Company's stock offerings and net earnings. 23

24 PROVISION (BENEFIT) FOR INCOME TAXES. CIENA's provision (benefit) for income taxes was 32.5%, (34.5%), and 44.2% of pre-tax earnings (loss) for fiscal 2000, 1999 and 1998, respectively. The income tax provision for 2000 was lower than the expected 35% primarily due to benefits from research and development tax credits. The benefit for fiscal 1999 was less than the expected statutory benefit of 35% due to non-deductible merger costs. The income tax provision for 1998 was higher than the expected statutory rate of 35%, due primarily to charges for purchased research and development and state tax charges related to the Alta acquisition. Purchased research and development charges are not deductible for tax purposes. Exclusive of the effect of these charges, the Company's provision for income taxes was 38.6% of income before income taxes in fiscal 1998. As of October 31, 2000 CIENA's deferred tax asset was $143.0 million. The realization of this asset could be adversely affected if future earnings are lower than anticipated. 24

26 CIENA's quarterly operating results have varied and are expected to vary in the future. The Company's detailed discussion of risk factors addresses the many factors that have caused such variation in the past, and may cause similar variations in the future. See "Risk Factors". CIENA's revenues have increased in each of the last eight quarters due to strong demand across existing products and introduction of new products such as MultiWave CoreStream configured for both 2.5 Gb/s and 10.0 Gb/s transmission rates. CIENA's gross margin percentage has improved from the first quarter fiscal 1999 to the fourth quarter fiscal 2000 as a result of component cost reductions, production efficiencies, and relative stable sales pricing. CIENA's operating expenses have increased in each of the last eight quarters due to continued investments in research and development, selling and marketing, and infrastructure activities. Exclusive of provisions for doubtful accounts and merger related costs, the Company's operating expenses as a percentage of revenues have generally decreased each of the last eight quarters. During fiscal 2001, CIENA's operating expenses will continue to increase in absolute dollars and may increase as percentage of revenue. We expect to preserve and enhance our market leadership and build on our installed base with new and additional products in conjunction with increased investments in selling, marketing, and customer service activities. See "Risk Factors". LIQUIDITY AND CAPITAL RESOURCES At October 31, 2000, CIENA's principal source of liquidity was its cash and cash equivalents. The Company had $143.2 million in cash and cash equivalents, and $95.1 million in corporate debt securities and U.S. Government obligations. The Company's corporate debt securities and U.S. Government obligations have contractual maturities of six months or less. The Company's operating activities provided cash of $59.0 million, $28.7 million, and $48.8 million for fiscal 2000, 1999, and 1998, respectively. Cash provided by operations in fiscal 2000 was primarily attributable to a net gain adjusted for the non-cash charges of depreciation, amortization, tax benefit related to exercise of stock options, provisions for doubtful accounts, inventory obsolescence, and warranty, increases in accounts payable, and accrued expenses, offset by increases in accounts receivable and inventories. Cash used in investing activities in fiscal 2000, 1999, and 1998 was $103.2 million, $149.7 million, and $107.0 million, respectively. Included in investment activities were additions to capital equipment and leasehold improvements in fiscal 2000, 1999, and 1998 of $123.9 million, $46.8 million, and $88.9 million, respectively. The capital equipment expenditures were primarily for test, manufacturing and computer equipment. The Company expects additional combined capital equipment and leasehold improvement expenditures of approximately $208 million to be made during fiscal 2001 to support selling and marketing, manufacturing and product development activities and the construction of leasehold improvements for its facilities. We generated $43.9 million, $13.8 million, and $35.6 million in cash from financing activities in fiscal 2000, 1999, and 1998, respectively. During fiscal 2000, CIENA received $44.0 million from the exercise of stock options and the sale of stock through our employee stock purchase plan. During fiscal 1999 CIENA received $11.3 million from the exercise of stock options, the sale of stock through our employee stock purchase plan, and from the additional capitalization of Omnia and Lightera. During fiscal 1998, CIENA received approximately $34.3 million from the issuance of stock associated with the capitalization of Omnia and Lightera, and from the exercise of stock options. We believe that our existing cash balances and investments, together with cash flow from operations, will be sufficient to meet our liquidity and capital spending requirements at least through the end of fiscal 2001. However, possible investments in or acquisitions of complementary businesses, products or technologies may require additional financing prior to such time. There can be no assurance that additional debt or equity financing will be available when required or, if available, can be secured on terms satisfactory to us. EFFECTS OF RECENT ACCOUNTING PRONOUNCEMENTS In June 1998, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 133 (SFAS No. 133), "Accounting for Derivative Instruments and Hedging Activities". This Statement requires companies to record derivatives on the balance sheet as assets or liabilities, measured at fair value. Gains or losses resulting from changes in the values of those derivatives would be accounted for depending on the use of the derivative and whether it qualifies for hedge accounting. SFAS No. 133, as amended by SFAS No. 137 "Accounting 26

27 for Derivative Instruments and Hedging Activities - Deferral of the Effective Date for SFAS No. 133", will be effective for the Company's fiscal year ending October 31, 2000. The Company believes the adoption of SFAS No. 133 and SFAS No. 137 will not have a material effect on the consolidated financial statements. In December 1999, the Securities and Exchange Commission released Staff Accounting Bulletin No. 101, "Revenue Recognition in Financial Statements," (SAB 101) which clarifies the Securities and Exchange Commission's view on revenue recognition. Subsequently, the SEC released SAB 101B, which delayed the implementation date of SAB 101 for registrants with fiscal years that begin between December 16, 1999 and March 15, 2000. CIENA is required to be in conformity with the provisions of SAB 101, as amended, no later than January 31, 2001, with the impact of such adoption being treated on a cumulative basis as of November 1, 2000. While management will continue to assess SAB 101, CIENA presently believes its existing revenue recognition policies and procedures are generally in compliance with SAB 101 and, therefore, SAB 101's adoption will have no material impact on CIENA's financial condition, results of operations or cash flows. In July 2000, the FASB's Emerging Issues Task Force ("EITF") reached a final consensus that the income tax benefit realized by a company upon the exercise of a nonqualified stock option or the disqualifying disposition of an incentive stock option should be classified in the operating section of the statement of cash flows. The consensus is effective for the Company's quarters ending after July 20, 2000. All comparative cash flow statements as presented have been restated to comply with this consensus. In September 2000, the FASB issued SFAS No. 140, "Accounting for the Transfers and Servicing of Financial Assets and Extinguishments of Liabilities." SFAS No. 140 is effective for transfers occurring after March 31, 2001 and for disclosures relating to the securitization transactions and collateral for fiscal years ending after December 15, 2000. The company believes the adoption of SFAS No. 140 will not have a material effect on the consolidated financial statements. RISK FACTORS Investing in our securities involves a high degree of risk. In addition to the other information contained in this annual report, including the reports we incorporate by reference, you should consider the following factors before investing in our securities. OUR RESULTS CAN BE UNPREDICTABLE Our ability to recognize revenue during a quarter from a customer depends upon our ability to ship product and satisfy other contractual obligations of a customer sale in that quarter. In general, revenue and operating results in any reporting period may fluctuate due to factors including: - loss of a customer; - the timing and size of orders from customers; - changes in customers' requirements, including changes to orders from customers; - the introduction of new products by us or our competitors; - changes in the price or availability of components for our products; - readiness of customer sites for installation; - satisfaction of contractual customer acceptance criteria and related revenue recognition issues; - manufacturing and shipment delays and deferrals; 27

28 - increased service, warranty or repair costs; - the timing and amount of employer payroll tax to be paid on employee gains on stock options exercised; and - changes in general economic conditions as well as those specific to the telecommunications and intelligent optical networking industries. Our intelligent optical networking products require a relatively large investment and our target customers are highly demanding and technically sophisticated. There are only a limited number of potential customers in each geographic market and each customer has unique needs. As a result, the sales cycles for our products are long, often more than a year between our initial contact with the customer and their commitment to purchase. We budget expense levels on our expectations of long-term future revenue. These budgets reflect our substantial investment in the financial, engineering, manufacturing and logistics support resources we think we may need for large potential customers, even though we do not know the volume, duration or timing of any purchases from them. In addition, we make a substantial investment in financial, manufacturing and engineering resources for the development of new and enhanced products. As a result, we may continue to experience high inventory levels, operating expenses and general overhead. We have experienced rapid expansion in all areas of our operations, particularly in the manufacturing of our products. Our future operating results will depend on our ability to continue to expand our manufacturing facilities in a timely manner so that we can satisfy our delivery commitments to our customers. Our failure to expand these facilities in a timely manner and meet our customer delivery commitments would harm our business, financial condition and results of operations. Our product development efforts will require us to incur ongoing development and operating expenses and any delay in the contributions from new products, such as the MultiWave CoreDirector product line and enhancements to our existing optical transport products, could harm our business. CHANGES IN TECHNOLOGY OR THE DELAYS IN THE DEPLOYMENT OF NEW PRODUCTS COULD HURT OUR NEAR TERM PROSPECTS The market for optical networking equipment is changing at a rapid pace. The accelerated pace of deregulation and the adoption of new technology in the telecommunications industry likely will intensify the competition for improved optical networking products. Our ability to develop, introduce and manufacture new and enhanced products will depend upon our ability to anticipate changes in technology, industry standards and customer requirements. Our failure to introduce new and enhanced products in a timely manner could harm our competitive position and financial condition. Several of our new products, including the MultiWave CoreDirector and the enhancements to the MultiWave CoreStream products, are based on complex technology which could result in unanticipated delays in the development, manufacture or deployment of these products. In addition, our ability to recognize revenue from these products could be adversely affected by the extensive testing required for these products by our customers. The complexity of technology associated with support equipment for these products could also result in unanticipated delays in their deployment. These delays could harm our competitive and financial condition. Competition from competitive products, the introduction of new products embodying new technologies, a change in the requirements of our customers, or the emergence of new industry standards could delay or hinder the purchase and deployment of our products and could render our existing products obsolete, unmarketable or uncompetitive from a pricing standpoint. The long certification process for new telecommunications equipment used in the networks of the regional Bell operating companies, referred to as RBOCs, has in the past resulted in and may continue to result in unanticipated delays which may affect the deployment of our products for the RBOC market. 28

29 WE FACE INTENSE COMPETITION WHICH COULD HURT OUR SALES AND PROFITABILITY The market for optical networking equipment is extremely competitive. Competition in the optical networking installation and test services market is based on varying combinations of price, functionality, software functionality, manufacturing capability, installation, services, scalability and the ability of the system solution to meet customers' immediate and future network requirements. A small number of very large companies, including Alcatel, Cisco Systems, Fujitsu Group, Hitachi, Lucent Technologies, NEC Corporation, Nortel Networks, Siemens AG and Telefon AB LM Ericsson, have historically dominated the telecommunications equipment industry. These companies have substantial financial, marketing, manufacturing and intellectual property resources. In addition, these companies have substantially greater resources to develop or acquire new technologies than we do and often have existing relationships with our potential customers. We sell systems that compete directly with product offerings of these companies and in some cases displace or replace equipment they have traditionally supplied for telecommunications networks. As such, we represent a specific threat to these companies. The continued expansion of our product offerings with the MultiWave CoreDirector product line and enhancements to our MultiWave CoreStream product line likely will increase this perceived threat. We expect continued aggressive tactics from many of these competitors, including: - price discounting; - early announcements of competing products and other marketing efforts; - "one-stop shopping" appeals; - customer financing assistance; - marketing and advertising assistance; and - intellectual property disputes. These tactics can be particularly effective in a highly concentrated customer base such as ours. Our customers are under increasing competitive pressure to deliver their services at the lowest possible cost. This pressure may result in pricing for optical networking systems becoming a more important factor in customer decisions, which may favor larger competitors that can spread the effect of price discounts in their optical networking products across a larger array of products and services and across a larger customer base than ours. If we are unable to offset any reductions in the average sales price for our products by a reduction in the cost of our products, our gross profit margins will be adversely affected. Our inability to compete successfully against our competitors and maintain our gross profit margins would harm our business, financial condition and results of operations. Many of our customers have indicated that they intend to establish a relationship with at least two vendors for optical networking products. With respect to customers for whom we are the only supplier, we do not know when or if these customers will select a second vendor or what impact the selection might have on purchases from us. If a second optical networking supplier is chosen, these customers could reduce their purchases from us, which could in turn have a material adverse effect on us. New competitors are emerging to compete with our existing products as well as our future products. There has been an increase in funding for new companies focused on the development of new products for the optical networking market. We expect new competitors to continue to emerge as the optical networking market continues to expand. These companies may achieve commercial availability of their products more quickly due to the narrow and exclusive focus of their efforts. Several of these competitors have raised significantly more cash and they have in some cases offered stock in their companies, positions on technical advisory boards, or have provided significant vendor financing to attract new customers. In particular, a number of companies, including several start-up companies and recently public companies that have raised substantial equity capital, have announced products that compete with our MultiWave CoreStream, MultiWave Metro, and MultiWave CoreDirector products. Our inability to compete successfully against these companies would harm our business, financial condition and results of operations. 29

30 WE MAY NOT BE ABLE TO SUCCESSFULLY COMPLETE DEVELOPMENT AND ACHIEVE COMMERCIAL ACCEPTANCE OF NEW PRODUCTS During the third quarter of fiscal 2000, the first version of our MultiWave CoreDirector became available. Our MultiWave CoreDirector CI product and enhancements to the MultiWave CoreDirector and MultiWave CoreStream product lines are in the development phase and are not yet ready for commercial manufacturing or deployment. We expect to offer additional releases of the MultiWave CoreDirector product over the life of the product and continue to enhance features of our MultiWave CoreStream product, including the longer reach and higher channel count functionality of our product line. The initial release of MultiWave CoreDirector CI is expected in limited availability for customer trials during the first quarter of calendar 2001. The maturing process from laboratory prototype to customer trials, and subsequently to general availability involves a number of steps, including: - completion of product development; - the qualification and multiple sourcing of critical components, including application-specific integrated circuits, referred to as ASICs; - validation of manufacturing methods and processes; - extensive quality assurance and reliability testing, and staffing of testing infrastructure; - validation of embedded software validation; - establishment of systems integration and systems test validation requirements; and - identification and qualification of component suppliers. Each of these steps in turn presents serious risks of failure, rework or delay, any one of which could decrease the speed and scope of product introduction and marketplace acceptance of the product. Specialized ASICs and intensive software testing and validation, in particular, are key to the timely introduction of enhancements to the MultiWave CoreDirector product line, and schedule delays are common in the final validation phase, as well as in the manufacture of specialized ASICs. In addition, unexpected intellectual property disputes, failure of critical design elements, and a host of other execution risks may delay or even prevent the introduction of these products. If we do not develop and successfully introduce these products in a timely manner, our business, financial condition and results of operations would be harmed. The markets for our MultiWave CoreDirector product line are relatively new. We have not established commercial acceptance of these products, and we cannot assure you that the substantial sales and marketing efforts necessary to achieve commercial acceptance in traditionally long sales cycles will be successful. If the markets for these products do not develop or the products are not accepted by the market, our business, financial condition and results of operations would suffer. WE DEPEND ON A LIMITED NUMBER OF SUPPLIERS AND FOR SOME ITEMS WE DO NOT HAVE A SUBSTITUTE SUPPLIER We depend on a limited number of suppliers for components of our products, as well as for equipment used to manufacture and test our products. Our products include several higher performance components for which reliable, high volume suppliers are particularly limited. Furthermore, certain key optical and electronic components we use in our optical transport systems are currently available only from sole sources, and in some cases, that sole source is also a competitor. A worldwide shortage of some electrical components has caused an increase in the price of components. Any delay in component availability for any of our products could result in delays in deployment of these products and in our ability to recognize revenues. These delays could harm our customer relationships. Failures of components can affect customer confidence in our products and could adversely affect our financial 30

31 performance and the reliability and performance of our products. On occasion, we have experienced delays in receipt of components and have received components that do not perform according to their specifications. Any future difficulty in obtaining sufficient and timely delivery of components could result in delays or reductions in product shipments which, in turn, could harm our business. A recent wave of consolidation among suppliers of these components, such as the recent purchases of E-TEK and SDL by JDS Uniphase, could adversely impact the availability of components on which we depend. Delayed deliveries of key components from these sources could adversely effect our business. Any delays in component availability for any of our products or test equipment could result in delays in deployment of these products and in our ability to recognize revenue from them. These delays could harm our customer relationships and our results of operations. WE RELY ON CONTRACT MANUFACTURERS FOR OUR PRODUCTS We rely on a small number of contract manufacturers to manufacture our CoreDirector product line and some of the components for our other products. The qualification of these manufacturers is an expensive and time consuming process and these contract manufacturers build modules for other companies, including for our competitors. In addition, we do not have contracts in place with each of these manufacturers. We may not be able to effectively manage our relationships with our manufacturers and we cannot be certain that they will be able to fill our orders in a timely manner. If we cannot effectively manage these manufacturers or they fail to deliver components in a timely manner it may have an adverse affect on our business and results of operations. SOME OF OUR SUPPLIERS ARE ALSO OUR COMPETITORS Some of our component suppliers are both primary sources for components and major competitors in the market for system equipment. For example, we buy components from: - Alcatel; - Lucent Technologies; - NEC Corporation; - Nortel Networks; and - Siemens AG. Each of these companies offers optical communications systems and equipment, which are competitive with our products. Also, Lucent is the sole source of two components and is one of two suppliers of two others. Recently, Lucent has announced that it intends to spin off a portion of its components business. Our supply of components from Lucent may be adversely effected by this restructuring. Alcatel and Nortel are suppliers of lasers used in our products and NEC is a supplier of an important piece of testing equipment. A decline in reliability or other adverse change in these supply relationships could harm our business. SALES TO EMERGING CARRIERS MAY INCREASE THE UNPREDICTABILITY OF OUR RESULTS As we continue to address emerging carriers, timing and volume of purchasing from these carriers can also be more unpredictable due to factors such as their need to build a customer base, acquire rights of way and interconnections necessary to sell network service, and build out new capacity, all while working within their capital budget constraints. Sales to these carriers may increase the unpredictability of our financial results because even these emerging carriers purchase our products in multi-million dollar increments. Unanticipated changes in customer purchasing plans also create unpredictability in our results. A portion of our anticipated revenue over the next several quarters is comprised of orders of less than $25 million each from several customers, some of which may involve extended payment terms or other financing assistance. Our ability to recognize revenue from financed sales to emerging carriers will depend on the relative financial condition of the 31

32 specific customer, among other factors. Further, we will need to evaluate the collectibility of receivables from these customers if their financial conditions deteriorate in the future. Purchasing delays and changes in the financial condition or the amount of purchases by any of these customers, could have a material adverse effect on us. In the past we have had to make provisions for the accounts receivables from customers that experienced financial difficulty. If additional customers face similar financial difficulties, our receivables from these customers may become uncollectible, we would have to write off the asset or decrease the value of the asset to the extent the receivable could not be collected. These write-downs or write-offs would adversely affect our financial performance. OUR ABILITY TO COMPETE COULD BE HARMED IF WE ARE UNABLE TO PROTECT AND ENFORCE OUR INTELLECTUAL PROPERTY RIGHTS OR IF WE INFRINGE ON INTELLECTUAL PROPERTY RIGHTS OF OTHERS We rely on a combination of patent, copyright, trademark and trade secret laws and restrictions on disclosure to protect our intellectual property rights. We also enter into non-disclosure and proprietary rights agreements with our employees and consultants, and license agreements with our corporate partners, and control access to and distribution of our products, documentation and other proprietary information. Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy or otherwise obtain and use our products or technology. Monitoring unauthorized use of our products is difficult and we cannot be certain that the steps we have taken will prevent unauthorized use of our technology, particularly in foreign countries where the laws may not protect our proprietary rights as fully as in the United States. If competitors are able to use our technology, our ability to compete effectively could be harmed. We are involved in an intellectual property dispute regarding the use of our technology and may become involved with additional disputes in the future. Such lawsuits can be costly and may significantly divert time and attention from some members of our personnel. We have received and may receive in the future, notices from holders of patents in the optical technology field that raise issues of possible infringement by our products. Questions of infringement in the optical networking equipment market often involve highly technical and subjective analysis. There can be no assurance that any of these patent holders or others will not in the future initiate legal proceedings against us, or that we will be successful in defending against these actions. We are involved in an intellectual property dispute regarding the possible infringement of our products. In the past, we have been forced to take a license from the owner of the infringed intellectual property, or to redesign or stop selling the product that includes the challenged intellectual property. If we are sued for infringement and are unsuccessful in defending the suit, we could be subject to significant damages and our business and customer relationships could be adversely affected. PRODUCT PERFORMANCE PROBLEMS COULD LIMIT OUR SALES PROSPECTS The production of new optical networking products and systems with high technology content involves occasional problems as the technology and manufacturing methods mature. If significant reliability, quality or network monitoring problems develop, including those due to faulty components, a number of negative effects on our business could result, including: - costs associated with reworking our manufacturing processes; - high service and warranty expenses; - high inventory obsolescence expense: - high levels of product returns; - delays in collecting accounts receivable; - reduced orders from existing customers; and - declining interest from potential customers. Although we maintain accruals for product warranties, actual costs could exceed these amounts. From time to time, there will be interruptions or delays in the activation of our products at a customer's site. These interruptions or delays may result from product performance problems or from aspects of the installation and activation activities, 32

33 some of which are outside our control. If we experience significant interruptions or delays that we can not promptly resolve, confidence in our products could be undermined, which could harm our business. OUR PROSPECTS DEPEND ON DEMAND WHICH WE CANNOT RELIABLY PREDICT OR CONTROL We may not anticipate changes in direction or magnitude of demand for our products. The product offerings of our competitors could adversely affect the demand for our products. In addition, unanticipated reductions in demand for our products could adversely affect us. Our products enable long distance optical transport, metropolitan optical transport, intelligent core switching and network management. Demand for our product depends on our customers' requirements. These requirements may vary significantly from quarter to quarter due to factors such as: - the type and quantity of optical equipment needed by our customers; - the timing of the deployment of optical equipment by our customers; - the rate at which our current customers fund their network build- outs; and - the equipment configurations and network architectures our customers want. Customer determinations are subject to abrupt changes in response to their own competitive pressures, capital requirements and financial performance expectations. These changes could harm our business. Recently we have experienced an increased level of sales activity that could lead to an upsurge in demand that is reflected in the overall increase in demand for optical networking and similar products in the telecommunications industry. Our results may suffer if we are unable to address this demand adequately by successfully scaling up our manufacturing capacity and hiring additional qualified personnel. To date we have largely depended on our own manufacturing and assembly facilities to meet customer expectations, but we cannot be sure that we can satisfy our customers' expectations in all cases by internal capabilities. In that case, we face the challenge of adequately managing customer expectations and finding alternative means of meeting them. If we fail to manage these expectations we could lose customers or receive smaller orders from customers. OUR SUCCESS LARGELY DEPENDS ON OUR ABILITY TO RETAIN KEY PERSONNEL Our success has always depended in large part on our ability to attract and retain highly-skilled technical, managerial, sales and marketing personnel, particularly those skilled and experienced with optical communications equipment. Our key founders and employees, together with the key founders and employees of acquired companies have received a substantial number of our shares and vested options that can be sold at substantial gains. In many cases, these individuals could become financially independent through these sales, before our future products have matured into commercially deliverable products. These circumstances may make it difficult to retain and motivate these key personnel. As we have grown and matured, competitors' efforts to hire our employees have intensified, particularly among competitive start-up companies and other early stage companies. We have agreements in place with most of our employees that limit their ability to work for a competitor and prohibit them from soliciting our other employees and our customers following termination of their employment. Our employees and our competitors may not respect these agreements. We have in the past been required to enforce, and are currently in the process of enforcing, some of these agreements. We expect in the future to continue to be required to resort to legal actions to enforce these agreements and could incur substantial costs in doing so. We may not be successful in these legal actions, and we may not be able to retain all of our key employees or attract new personnel to add to or replace them. The loss of key personnel would likely harm our business. 33

34 PART OF OUR STRATEGY INVOLVES PURSUING STRATEGIC ACQUISITIONS THAT MAY NOT BE SUCCESSFUL As part of our strategy for growth, we will consider acquiring businesses that are intended to accelerate our product and service development processes and add complementary products and services. We may issue equity or incur debt to finance these acquisitions. Acquisitions involve a number of operational risks, including risks that the acquired business will not be successfully integrated, may distract management attention and may involve unforeseen costs and liabilities. OUR STOCK PRICE MAY EXHIBIT VOLATILITY Our common stock price has experienced substantial volatility in the past, and is likely to remain volatile in the future. Volatility can arise as a result of the activities of short sellers and risk arbitrageurs, and may have little relationship to our financial results or prospects. Volatility can also result from any divergence between our actual or anticipated financial results and published expectations of analysts, and announcements that we, our competitors, or our customers may make. Divergence between our actual results and our anticipated results, analyst estimates and public announcements by us, our competitors, or by customers will likely occur from time to time in the future, with resulting stock price volatility, irrespective of our overall year-to-year performance or long-term prospects. As long as we continue to depend on a limited customer base, and particularly when a substantial majority of their purchases consist of newly-introduced products like the MultiWave CoreStream, MultiWave CoreDirector and MultiWave Metro, there is substantial risk that our quarterly results will vary widely. ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK The following discussion about the Company's market risk disclosures involves forward-looking statements. Actual results could differ materially from those projected in the forward-looking statements. The Company is exposed to market risk related to changes in interest rates and foreign currency exchange rates. The Company does not use derivative financial instruments for speculative or trading purposes. INTEREST RATE SENSITIVITY. The Company maintains a short-term investment portfolio consisting mainly of corporate debt securities and U.S. government agency discount notes with an average maturity of less than six months. These held-to-maturity securities are subject to interest rate risk and will fall in value if market interest rates increase. If market interest rates were to increase immediately and uniformly by 10 percent from levels at October 31, 2000, the fair value of the portfolio would decline by approximately $2.6 million. The Company has the ability to hold its fixed income investments until maturity, and therefore the Company would not expect its operating results or cash flows to be affected to any significant degree by the effect of a sudden change in market interest rates on its securities portfolio. FOREIGN CURRENCY EXCHANGE RISK. As a global concern, the Company faces exposure to adverse movements in foreign currency exchange rates. These exposures may change over time as business practices evolve and could have a material adverse impact on the Company's financial results. Historically the Company's primary exposures have been related to nondollar-denominated operating expenses in Canada, Europe and Asia where the Company sells primarily in U.S. dollars. The introduction of the Euro as a common currency for members of the European Monetary Union began during the Company's fiscal year 2000. The foreign currency exposure resulting from the introduction of the Euro has been immaterial to the operating results of the Company. The Company is prepared to hedge against fluctuations in the Euro if this exposure becomes material. As of October 31, 2000, the assets and liabilities of the Company related to non-dollar denominated currencies was not material. Therefore an increase or decrease of 10 percent in the foreign exchange rate would not have a material impact on the Company's financial position. 34

36 REPORT OF INDEPENDENT ACCOUNTANTS To the Board of Directors and Stockholders of CIENA Corporation In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of operations, of cash flows and of changes in stockholders' equity present fairly, in all material respects, the financial position of CIENA Corporation and its subsidiaries at October 31, 2000 and 1999, and the results of their operations and their cash flows for each of the three years in the period ended October 31, 2000, in conformity with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of the Company's management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements in accordance with auditing standards generally accepted in the United States of America, which require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. PricewaterhouseCoopers LLP McLean, VA December 6, 2000 36

41 CIENA CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (1) THE COMPANY AND SIGNIFICANT ACCOUNTING POLICIES Description of Business CIENA is a leader in the rapidly growing intelligent optical networking equipment market. CIENA offers a comprehensive portfolio of products for communications service providers worldwide. CIENA's customers include long-distance carriers, competitive and incumbent local exchange carriers, Internet service providers and wholesale carriers. CIENA offers optical transport and intelligent optical switching systems that enable service providers to provision, manage and deliver high-bandwidth services to their customers. The Company has pursued a strategy to develop and leverage the power of disruptive technologies to change the fundamental economics of building carrier-class tele- and data-communications networks, thereby providing our customers with a competitive advantage. CIENA's intelligent optical networking products are designed to enable carriers to deliver any time, any size, any priority bandwidth to their customers. Principles of Consolidation The Company has fifteen wholly owned U.S. and international subsidiaries which have been consolidated in the accompanying financial statements. The Company completed a merger with Omnia Communications, Inc. ("Omnia"), a Delaware company headquartered in Marlborough, Massachusetts, on July 1, 1999. On March 31, 1999 the Company completed a merger with Lightera Networks, Inc. ("Lightera"), a Delaware company headquartered in Cupertino, California. On February 19, 1998, the Company completed a merger with ATI Telecom International Ltd. ("Alta"). Each of these transactions constituted a tax-free reorganization and have been accounted for as pooling of interests under Accounting Principles Board Opinion No. 16. Accordingly, all prior period consolidated financial statements presented have been restated to include the combined results of operations, financial position and cash flows of each of the companies as though they had been a part of CIENA. The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All material intercompany accounts and transactions have been eliminated in consolidation. 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 (October 28, 2000, October 30, 1999 and October 31, 1998). For purposes of financial statement presentation, each fiscal year is described as having ended on October 31. Fiscal 2000, 1999, and 1998 were comprised of 52 weeks. Prior to the merger, Omnia's fiscal year ended on December 31. Since the fiscal years for CIENA and Omnia differed prior to the merger, the periods combined for the purposes of the consolidated financial statements are as follows: CIENA Omnia Fiscal year ended October 31, 1997 June 3, 1997 (date of inception) to December 31, 1997 Fiscal year ended October 31, 1998 January 1, 1998 to December 31, 1998 The fiscal year ended October 31, 1999 contains two months of Omnia's financial results, which are also recorded in the fiscal year ending October 31, 1998. The net loss for these two months, November and December 1998, was $1,621,000. 41

42 Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires the Company to make estimates, judgements 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. Actual results could differ from the recorded estimates. Cash and Cash Equivalents The Company considers all highly liquid investments purchased with original maturities of three months or less to be cash equivalents. Marketable Debt Securities The Company has classified its investments in marketable debt securities as held-to-maturity securities as defined by Statement of Financial Accounting Standards No. 115, "Accounting for Certain Investments in Debt and Equity Securities". Such investments are recorded at their amortized cost in the accompanying consolidated balance sheets. All of the marketable debt securities are corporate debt securities with contractual maturities of six months or less and such instruments have $11,000 and $70,255 of unrealized gains and $108,000 and $32,000 of unrealized loss, as of October 31, 1999 and 2000, respectively. See Note 3. 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 2-10 years for leasehold improvements. Goodwill The Company has recorded goodwill from three purchase transactions. See Note 2. It is the Company's policy to periodically assess the carrying amount of its goodwill to determine if there has been an impairment to its carrying value. The Company would record any such impairment when identified. Concentrations Substantially all of the Company's cash and cash equivalents are custodied at four major U.S. financial institutions. The majority of the Company's cash equivalents include U.S. Government Federal Agency Securities, short-term marketable securities, and overnight repurchase agreements. Deposits held with banks may exceed the amount of insurance provided on such deposits. Generally these deposits may be redeemed upon demand and, therefore, bear minimal risk. Historically, the Company has relied on a limited number of customers for a substantial portion of its revenue. During fiscal year 2000, Sprint, Qwest Communications and GTS Network Ltd. each accounted for at least 10% or more of CIENA's revenue and all three combined accounted for 60.9% of the Company's fiscal 2000 revenue. During fiscal year 1999 Sprint, MCI WorldCom, and GTS Network Ltd. each accounted for at least 10% or more of CIENA's revenue and all three combined accounted for 46.2% of the Company's fiscal 1999 revenue. During fiscal 1998 Sprint was the only 10% customer and in total accounted for 52.5 % of the Company's fiscal 1998 revenue. The Company expects that a significant portion of its future revenue will continue to be generated by a limited number of customers. The loss of any one of these customers or any substantial reduction in orders by any one of these customers could materially adversely affect the Company's financial condition or operating results. Additionally, the Company's 42

43 access to certain raw materials is dependent upon single and sole source suppliers. The inability of any supplier to fulfill supply requirements of the Company could impact future results. CIENA performs ongoing credit evaluations of its customers and generally does not require collateral from its customers. CIENA maintains an allowance for potential losses when identified. CIENA's allowance for doubtful accounts as of October 31, 2000 was $29.6 million. Approximately $27.8 million relates to provisions made for doubtful accounts associated with iaxis Limited, one of CIENA's European customers. In September 2000, CIENA was informed that an administrative order had been issued by a London court against iaxis Limited. As a result of this order, joint administrators were appointed to manage the business of iaxis Limited while they marketed the business for sale and formulated a reorganization of the company. In November 2000, CIENA was notified that Dynegy Inc. and its subsidiaries had entered into a proposed agreement to acquire the assets and stock of iaxis Limited from the administrators. As a consequence of the terms of (a) the proposed agreement between the administrators of iaxis Limited and Dynegy, and of (b) a related sales agreement between CIENA and Dynegy, CIENA expects to realize approximately $8.9 million of the gross outstanding accounts receivable balance due from iaxis Limited as of October 31, 2000. While the proposed purchase agreement between the administrators of iaxis Limited and Dynegy is subject to certain administrative and judicial approvals, CIENA believes that such approvals will be ultimately obtained and that CIENA will be successful in collecting the net $8.9 million outstanding accounts receivable balance from the customer. However, should such approvals not occur, additional write-offs might be required. As of October 31, 2000, the trade accounts receivable included three customers who each accounted for 28%, 16%, and 13% of the trade accounts receivable, respectively. As of October 31, 1999, the trade accounts receivable included three customers who each accounted for 30%, 14%, and 12% of the trade accounts receivable, respectively. Revenue Recognition CIENA recognizes product revenue in accordance with the shipping terms specified and where collection is probable. For transactions where CIENA has yet to obtain customer acceptance, revenue is deferred until the terms of acceptance are satisfied. Revenue for installation services is recognized as the services are performed unless the terms of the supply contract combine product acceptance with installation, in which case revenues for installation services are recognized when the terms of acceptance are satisfied and installation is completed. Revenues from installation service fixed price contracts are recognized on the percentage-of-completion method, measured by the percentage of costs incurred to date compared to estimated total costs for each contract. Amounts received in excess of revenue recognized are included as deferred revenue in the accompanying balance sheets. For transactions involving the sale of software, revenue is recognized in accordance with Statement of Position No. 97-2 (SOP 97-2), "Software Revenue Recognition", including deferral of revenue recognition in instances where vendor specific objective evidence for undelivered elements is not determinable. For distributor sales where risks of ownership have not transferred, CIENA recognizes revenue when the product is shipped through to the end user. 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 after the product has been accepted. 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, 43

44 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. Valuation allowances are provided if, based upon the weight of the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. Tax savings resulting from deductions associated with stock options and certain stock warrants are credited directly to additional paid in capital when realization of such benefit is fully assured and to deferred tax liabilities prior to such point. See Note 9. Fair Value of Financial Instruments The carrying amounts of the Company's financial instruments, which include marketable debt securities, accounts receivable, accounts payable, and other accrued expenses, approximate their fair values due to their short maturities. Foreign Currency Translation The majority of the Company's foreign branches and subsidiaries use the U.S. dollar as their functional currency, as the U.S. parent exclusively funds the branches and subsidiaries' operations with U.S. dollars. For those subsidiaries using the local currency as their functional currency, assets and liabilities are translated at exchange rates in effect at the balance sheet date. Resulting translation adjustments are recorded directly to a separate component of stockholders' equity. Where the U.S. dollar is the functional currency, translation adjustments are recorded in other income. The net gain (loss) on foreign currency re-measurement and exchange rate changes for fiscal 1998, 1999 and 2000 was immaterial for separate financial statement presentation . Computation of Basic Net Income (Loss) per Common Share and Diluted Net Income (Loss) per Common and Dilutive Potential Common Share The Company calculates earnings per share in accordance with the Statement of Financial Accounting Standards No. 128, "Earnings per Share" (SFAS No. 128). SFAS No. 128 simplifies the earnings per share (EPS) computation and replaces the presentation of primary EPS with a presentation of basic EPS. This statement also requires dual presentation of basic and diluted EPS on the face of the income statement for entities with a complex capital structure and requires a reconciliation of the numerator and denominator used for the basic and diluted EPS computations. See Note 7. 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", which is effective for the Company's consolidated financial statements for fiscal years 1998, 1999, and 2000. SFAS No. 123 allows companies to either account for stock-based compensation under the new provisions of SFAS No. 123 or using the intrinsic value method provided by Accounting Principles Board Opinion No. 25 (APB No. 25), "Accounting for Stock Issued to Employees", but requires pro forma disclosure in the footnotes to the financial statements as if the measurement provisions of SFAS No. 123 had been adopted. The Company has elected to continue to account for its stock based compensation in accordance with the provisions of APB No. 25 as interpreted by FASB Interprettion No. 44, "Accounting for Certain Transactions Involving Stock Compensation, and Interpretation of APB Opinion No. 25", ("FIN 44") and present the pro forma disclosures required by SFAS No. 123. See Note 10. 44

45 Segment Reporting In June 1997, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 131 (SFAS No. 131), "Disclosures about Segments of an Enterprise and Related Information". The Statement is effective for the Company's fiscal year 1999. SFAS No. 131 establishes annual and interim reporting standards for operating segments of a company. It also requires entity-wide disclosures about the products and services an entity provides, the material countries in which it holds assets and reports revenues, and its major customers. The Company is not organized by multiple operating segments for the purpose of making operating decisions or assessing performance. Accordingly, the Company operates in one operating segment and reports only certain enterprise-wide disclosures. Newly Issued Accounting Standards In June 1998, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 133 (SFAS No. 133), "Accounting for Derivative Instruments and Hedging Activities". This Statement requires companies to record derivatives on the balance sheet as assets or liabilities, measured at fair value. Gains or losses resulting from changes in the values of those derivatives would be accounted for depending on the use of the derivative and whether it qualifies for hedge accounting. SFAS No. 133, as amended by SFAS No. 137, "Accounting for Derivative Instruments and Hedging Activities - Deferral of the Effective Date for SFAS No. 133", will be effective for the Company's fiscal year ending October 31, 2001. The Company believes the adoption of SFAS No. 133 and SFAS No. 137 will not have a material effect on the consolidated financial statements. In December 1999, the Securities and Exchange Commission released Staff Accounting Bulletin No. 101, "Revenue Recognition in Financial Statements," (SAB 101) which clarifies the Securities and Exchange Commission's view on revenue recognition. Subsequently, the SEC released SAB 101B, which delayed the implementation date of SAB 101 for registrants with fiscal years that begin between December 16, 1999 and March 15, 2000. The Company is required to be in conformity with the provisions of SAB 101, as amended, no later than January 31, 2001, with the impact of such adoption being treated on a cumulative basis as of November 1, 2000. While management will continue to assess SAB 101, CIENA presently believes its existing revenue recognition policies and procedures are generally in compliance with SAB 101 and, therefore, SAB 101's adoption will have no material impact on CIENA's financial condition, results of operations or cash flows. In July 2000, the FASB's Emerging Issues Task Force ("EITF") reached a final consensus that the income tax benefit realized by a company upon the exercise of a nonqualified stock option or the disqualifying disposition of an incentive stock option should be classified in the operating section of the statement of cash flows. The consensus is effective for the Company's quarters ending after July 20, 2000. All comparative cash flow statements as presented have been restated to comply with this consensus. In September 2000, the FASB issued SFAS No. 140, "Accounting for the Transfers and Servicing of Financial Assets and Extinguishments of Liabilities." SFAS No. 140 is effective for transfers occurring after March 31, 2001 and for disclosures relating to the securitization transactions and collateral for fiscal years ending after December 15, 2000. The company is reviewing the provisions of SFAS No. 140. Reclassification Certain prior year amounts have been reclassified to conform to current year consolidated financial statement presentation. 45

46 (2) BUSINESS COMBINATIONS Omnia On July 1, 1999, the Company completed a merger with Omnia in a transaction valued at approximately $483 million. Omnia is a telecommunications equipment supplier which focuses on developing solutions to allow public telephone network operators to offer services cost effectively over integrated metropolitan fiberoptic access and transport networks. Under the terms of the merger agreement, the Company acquired all of the outstanding shares and assumed the stock options of Omnia in exchange for approximately 30.4 million shares of CIENA common stock and 1.6 million CIENA shares issuable upon exercise of stock options. The transaction constituted a tax-free reorganization and has been accounted for as a pooling of interests under Accounting Principles Board Opinion No. 16. Accordingly, all prior period consolidated financial statements presented have been restated to include the combined results of operations, financial position and cash flows of Omnia as though it had been a part of CIENA. The following table shows the separate historical results of CIENA and Omnia for the periods prior to the consummation of the merger of the two entities. No financial information has been presented for the fiscal year ended 1996 as Omnia did not commence operations until June 1997. Omnia's fiscal year end was December 31. CIENA's results for the years ended October 31, 1997 and 1998 include Omnia's financial results from June 3, 1997 (date of inception) to December 31, 1997 and January 1, 1998 to December 31, 1998, respectively (in thousands).

Lightera is a developer of carrier class optical core switches for fiberoptic communications networks. Under the terms of the merger agreement, the Company acquired all of the outstanding shares and assumed outstanding stock options and warrants of Lightera in exchange for approximately 35.0 million shares of CIENA common stock and 5.8 million CIENA shares issuable upon exercise of stock options and warrants. The transaction constituted a tax-free reorganization and has been accounted for as a pooling of interests under Accounting Principles Board Opinion No. 16. Accordingly, all prior period consolidated financial statements presented have been restated to include the combined results of operations, financial position and cash flows of Lightera as though it had been a part of CIENA. 46

47 The following table shows the separate historical results of CIENA and Lightera for the periods prior to the consummation of the merger of the two entities. No financial information has been presented for the fiscal year ended 1997 as Lightera did not commence operations until April 1998 (in thousands). Year Ended Six Months Ended October 31, April 30, --------------- -------------------- 1998 1999 --------------- -------------------- Revenues: CIENA $ 508,087 $ 211,907 Lightera - - Intercompany eliminations - - --------------- -------------------- Consolidated revenues $ 508,087 $ 211,907 =============== ==================== Net income (loss): CIENA $ 53,194 $ 8,046 Lightera (2,081) (6,169) --------------- -------------------- Consolidated net income $ 51,113 $ 1,877 =============== ==================== Terabit During April 1998, the Company completed an Agreement and Plan of Reorganization with Terabit Technology, Inc. ("Terabit"), a developer of optical components known as photodetectors or optical receivers. Terabit is located in Santa Barbara, California. The purchase price was approximately $11.5 million and consisted of the issuance of 268,780 shares of CIENA common stock, the payment of $1.1 million in cash, and the assumption of certain stock options. The transaction was recorded using the purchase accounting method with the purchase price representing approximately $9.5 million in purchased research and development, $1.8 million in goodwill and other intangibles, and approximately $0.2 million in net assets assumed. The amortization period for the intangibles, based on management's estimate of the useful life of the acquired technology, is five years. The operations of Terabit are not material to the consolidated financial statements of the Company and, accordingly, separate pro forma financial information has not been presented. In connection with the Terabit acquisition, the Company recorded a $9.5 million charge in the year ended October 31, 1998 for purchased research and development. This generally represents the estimated value of purchased in-process technology related to Terabit's avalanche photodiodes (APD) that had not yet reached technological feasibility and had no alternative future use at the time of the acquisition. The amount of purchase price allocated to in-process research and development was determined using the discounted cash flow method. This method consisted of estimating future net cash flows attributable in-process APD technology for a discrete projection period and discounting the net cash flows back to their present value. The discount rate includes a factor that takes into account the uncertainty surrounding the successful development of the purchased in-process technology. The estimated revenue associated with the APD technology future net cash flows assumed a five year compound annual growth rate of between 5% to 43%. The revenue growth rates were developed considering, among other things, the current and expected industry trends and acceptance of the technologies in historical growth rates for similar industry products. Management's estimates or projections were based upon an estimated period of ten years with revenues reaching a peak in 2002 and declining through 2008. The estimated net cash flows were discounted to present value at a rate of return, which considers the relative risk of achieving the net cash flows and the time value of money. A 30% discount rate was used to effect the risk associated with Terabit's APD technology. This rate is higher than the Company's normal discount rate due to inherent uncertainties surrounding the successful development of purchase in-process technology, the useful life of the technology, and the profitability levels of such technology. The resulting net cash flows from the APD project was based on management's estimates of revenues, cost of sales, research and development costs, selling general and administrative costs, and income taxes associated with the project. Alta 47

48 On February 19, 1998, the Company completed a merger with ATI Telecom International Ltd., ("Alta"), a Canadian corporation headquartered near Atlanta, Georgia, in a transaction valued at approximately $52.5 million. Alta provides a range of engineering, furnishing and installation services for telecommunications service providers in the areas of transport, switching and wireless communications. Under the terms of the merger agreement, the Company exchanged 2 million shares of its common stock for all the common stock of Alta. The merger constituted a tax-free reorganization and has been accounted for as a pooling of interests under Accounting Principles Board Opinion No. 16. Accordingly, all prior period consolidated financial statements presented have been restated to include the combined results of operations, financial position and cash flows of Alta as though it had been a part of CIENA. Prior to the merger, Alta's year ended on December 31. In recording the business combination, Alta's prior period financial statements have been restated to conform to CIENA's fiscal year end. All intercompany transactions between CIENA and Alta have been eliminated in consolidation. Certain reclassifications were made to Alta financial statements to conform to CIENA's presentation. No material adjustments were made to conform to CIENA's accounting policies. The following table shows the separate historical results of CIENA and Alta for the periods prior to the consummation of the merger of the two entities (in thousands): Year Ended October 31, --------------------------------------- 1996 1997 ------------------- ------------------- Revenues: CIENA $ 54,838 $ 373,827 Alta 33,625 39,531 Intercompany eliminations - (143) ------------------- ------------------- Consolidated revenues $ 88,463 $ 413,215 =================== =================== Net income (loss): CIENA $ 14,718 $ 112,945 Alta 2,545 3,022 ------------------- ------------------- Consolidated net income $ 17,263 $ 115,967 =================== =================== Astracom During December 1997, the Company completed an Agreement and Plan of Merger with Astracom, Inc. ("Astracom"), an early stage telecommunications company located in Atlanta, Georgia. The purchase price was approximately $13.1 million and consisted of the issuance of 339,508 shares of CIENA common stock, the payment of $2.4 million in cash, and the assumption of certain stock options. The transaction was recorded using the purchase accounting method with the purchase price representing approximately $11.4 million in goodwill and other intangibles, and approximately $1.7 million in net assets assumed. The amortization period for the intangibles, based on management's estimate of the useful life of the acquired technology, is five years. The operations of Astracom are not material to the consolidated financial statements of the Company and, accordingly, separate pro forma financial information has not been presented.

50 (7) EARNINGS (LOSS) PER SHARE CALCULATION The following is a reconciliation of the numerators and denominators of the basic net income (loss) per common share ("basic EPS") and diluted net income (loss) per common and dilutive potential common share ("diluted EPS"). Basic EPS is computed using the weighted average number of common shares outstanding. Diluted EPS is computed using the weighted average number of common shares outstanding, stock options and warrants using the treasury stock method (in thousands except per share amounts).

(8) STOCKHOLDERS' EQUITY Authorized Shares On March 16, 2000, the shareholders of the Company approved an increase to the authorized number of shares of common stock from 360 million to 460 million shares. Stock Split The Board of Directors authorized the splitting of the Company's common stock on a two-for-one basis for shareholders of record on August 28, 2000 and the resulting shares from the split were distributed on September 18, 2000. All references to share and per-share data for all periods presented have been adjusted to give effect to this two-for-one stock split. Stockholder Rights Plan In December 1997, the Company's Board of Directors adopted a Stockholder Rights Plan. This plan is designed to deter any potential coercive or unfair takeover tactics in the event of an unsolicited takeover attempt. It is not intended to prevent a takeover of the Company on terms that are favorable and fair to all shareholders and will not interfere with a merger approved by the Board of Directors. Each right entitles shareholders to buy a "unit" equal to one one-thousandth of a share of Preferred Stock of the Company. The rights will be exercisable only if a person or a group acquires or announces a tender or exchange offer to acquire 15% or more of the Company's common stock or if the Company enters into certain other business combination transactions not approved by the Board of Directors. In the event the rights become exercisable, the rights plan allows for CIENA shareholders to acquire stock of the surviving corporation, whether or not CIENA is the surviving corporation, having a value twice that of the exercise price of the rights. The rights were distributed to shareholders of record in January 1998. The rights will expire December 2007 and are redeemable for $0.001 per right at the approval of the Company's Board of Directors. 50

51 Other Offerings During 1998 and 1999 Omnia issued 10,753,330 and 368,990 shares of common stock in exchange for approximately $12,801,000 and $66,000, respectively. During 1998, Lightera issued a total of 33,155,010 shares of common stock in exchange for certain technology rights, notes receivable totaling $211,000 and proceeds of approximately $15,893,000. In 1999, Lightera issued 1,937,022 shares of common stock in exchange for approximately $104,000.

Management believes that, after considering the anticipated future operating results of the Company, the net deferred tax assets will be realized. However, there cannot be complete assurance that this will occur. The income tax provision does not reflect the tax savings resulting from deductions associated with the Company's stock option plans. Tax benefits from exercises of stock options of approximately $11.0 million and $154.6 million in fiscal 1999 and fiscal 2000, respectively, were credited directly to additional paid-in-capital. The IRS is currently examining the Company's federal income tax returns for fiscal 1997 and fiscal 1998. Management does not expect the outcome of these examinations to have a material adverse affect on the Company's consolidated financial position, results of operations or cash flows. (10) EMPLOYEE BENEFIT PLANS Stock Incentive Plans In August of 1999, the Company approved the 1999 Non-Officer Incentive Stock Plan (the "1999 Plan"). Under the 1999 Plan, 24,000,000 shares of the Company's authorized but unissued Common Stock are reserved for options issuable to employees who are not executive officers of the Company. These options vest to the employee over four years and are exercisable once vested. Options under the 1999 Plan are categorized as non-qualified, and the exercise 52

53 price for each option shall be established by the Board of Directors provided the price is not less than 85% of fair market value. The Company has an Amended and Restated 1994 Stock Option Plan (the "1994 Plan"). Under the 1994 Plan, 40,100,000 shares of the Company's authorized but unissued Common Stock are reserved for options issuable to employees. Certain of 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, 1,500,000 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-qualified 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 85% of fair market value for non-qualified stock options. As a result of the Company's merger with Omnia, the Company assumed the Omnia 1997 Stock Plan Option Plan ("the 1997 Plan"). The 1997 Plan provided for the granting of stock options to employees and consultants of Omnia. Options granted under the 1997 Plan were either incentive stock options or nonstatutory stock options. Incentive stock options ("ISO"), could be granted only to Omnia employees (including officers and directors who were also employees). Nonstatutory stock options ("NSO") could be granted to Omnia employees and consultants. The Company has reserved 1,519,778 shares of Common Stock for outstanding options under the plan. Options exercised are immediately subject to a repurchase right held by the Company which lapse over a maximum period of four years at such times and under such conditions as determined by the Board of Directors. To date, options granted generally vest over four years. As a result of the Company's merger with Lightera, the Company assumed the Lightera 1998 Stock Option Plan ("the 1998 Plan"). The 1998 Plan provided for the granting of stock options to employees and consultants of Lightera. Options granted under the 1998 Plan were either incentive stock options or nonstatutory stock options. Incentive stock options ("ISO"), could be granted only to Lightera employees (including officers and directors who were also employees). Nonstatutory stock options ("NSO") could be granted to Lightera employees and consultants. The Company has reserved 5,058,322 shares of Common Stock for outstanding options under the plan. Options exercised are immediately subject to a repurchase right held by the Company which lapse over a maximum period of five years at such times and under such conditions as determined by the Board of Directors. To date, options granted generally vest over four years.

54 A total of 5.8 million options with an average exercise price of $21.44 were cancelled and reissued at $6.19 per share. At October 31, 2000, approximately 0.4 million shares of Common Stock subject to repurchase by the Company had been issued upon the exercise of options and restricted stock purchase agreements, 7.0 million of the total outstanding options were vested and not subject to repurchase by the Company upon exercise. As of October 31, 2000, approximately 14.5 million shares are available for issuance under these plans.

Approximately 693,000 and 607,000 shares of common stock have been issued for $5.8 million and $3.3 million during fiscal 2000 and fiscal 1999, respectively. As of October 31, 2000 approximately 3.7 million shares are available for issuance under this plan. Pro forma Stock-Based Compensation Had compensation cost for the Company's stock option plans and the Purchase Plan been determined based on the fair value at the grant date for awards in fiscal years 1998, 1999 and 2000 consistent with the provisions of SFAS No. 123, the Company's net income and net income per share for fiscal 1998 and 1999 would have been decreased and the net loss per share for fiscal 1999 would have been increased to the pro forma amounts indicated below (in thousands, except per share): October 31, ---------------------------------- 1998 1999 2000 -------- --------- ---------- Net income (loss) applicable to common stockholders - as reported...................................... $ 45,700 $ (3,924) $ 81,387 ======== ========= ========== Net income (loss) applicable to common stockholders - pro forma....................................... $ 20,816 $ (40,067) $ (26,244) ======== ========= ========== Basic net income (loss) per share - as reported....... $ 0.19 $ (0.01) $ 0.29 ======== ========= ========== Basic net income (loss) per share - pro forma......... $ 0.09 $ (0.15) $ (0.09) ======== ========= ========== Diluted net income (loss) per share - as reported..... $ 0.18 $ (0.01) $ 0.27 ======== ========= ========== Diluted net income (loss) per share - pro forma....... $ 0.08 $ (0.15) $ (0.09) ======== ========= ========== 54

55 The above pro forma disclosures are not necessarily representative of the effects on reported net income or loss for future years. The weighted average fair value of each option granted under the various stock option plans for 1998, 1999 and 2000 is $7.59, $9.45 and $64.99 respectively. The fair value of each option grant is estimated on the date of grant using the Black-Scholes Option Pricing Model with the following weighted average assumptions for fiscal years 1998, 1999, and 2000: Employee Stock Option Plans Employee Stock Purchase Plan October 31, October 31, --------------------------- ---------------- 1998 1999 2000 1999 2000 ---- ---- ----- ----- ---- Expected volatility 109% 88% 106% 88% 106% Risk-free interest rate 4.4% 5.5% 6.1% 5.5% 6.1% Expected life (years) 3.0 2.8 2.7 0.5 0.5 Expected dividend yield 0.0% 0.0% 0.0% 0.0% 0.0% The Black-Scholes option pricing model was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable. In addition, option pricing models require the input of highly subjective assumptions including the expected stock price volatility. The Company uses projected volatility rates, which are based upon historical volatility rates trended into future years. Because the Company's employee stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, in management's opinion, the existing models do not necessarily provide a reliable single measure of the fair value of the Company's options. Employee 401(k) Plan The Company has a 401(k) defined contribution profit sharing plan. The plan covers all full-time employees who 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 pre-tax 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 plan includes an employer matching contribution equal to 100% of the first 3% of participating employee contributions, with a five year vesting plan applicable to the Company's contribution with the exception that participants vest immediately upon turning age fifty-five. The Company has made no profit sharing contributions to date. During fiscal 1998 1999 and 2000 the Company made matching contributions of approximately $1.1 million, $1.7 million and $2.3 million, respectively. (11) COMMITMENTS AND CONTINGENCIES Operating Lease Commitments The Company has certain minimum obligations under non-cancelable operating leases expiring on various dates through 2006 for equipment and facilities. Future annual minimum rental commitments under non-cancelable operating leases at October 31, 2000 are as follows (in thousands): Fiscal year ending October 31, 2001.................................... $ 14,102 2002.................................... 12,293 2003.................................... 10,731 2004.................................... 10,706 2005.................................... 10,111 Thereafter.............................. 22,668 -------------- $ 80,611 ============== 55

56 Rental expense for fiscal 1998, 1999 and 2000 was approximately $6.1 million, $9.5 million and $13.7 million, respectively. Litigation On October 3, 2000, Stanford University and Litton Systems filed a complaint in U.S. District Court for the Central District of California alleging that optical fiber amplifiers incorporated into CIENA's products infringe U.S. Patent No. 4,859,016. Due to the early stage of this litigation, CIENA is unable to determine whether the litigation will have an adverse effect on the Company. The Company intends to defend this suit vigorously. On July 19, 2000, CIENA and CIENA Properties, Inc., a wholly owned subsidiary of CIENA, filed a complaint in the United States District Court for the District of Delaware requesting damages and injunctive relief against Corvis Corporation. The complaint charges Corvis Corporation with infringing three patents relating to CIENA's optical networking communication systems and technology. On September 8, 2000, Corvis filed an Answer and Counterclaim alleging invalidity, non-infringement and unenforceability of the asserted patents, and tortious interference with prospective economic advantage. CIENA believes that Corvis' counterclaims are without merit, and intends to defend itself vigorously. On June 1, 1998, the Company resolved the long-standing litigation with Pirelli S.p.A. The terms of the settlement involve dismissal of Pirelli's three lawsuits against CIENA previously pending in Delaware, dismissal of CIENA's legal proceedings against Pirelli in the United States International Trade Commission, a worldwide, non-exclusive cross-license to each party's patent portfolios, and a five-year moratorium on future litigation between the parties. As a result of the settlement, CIENA recorded a charge for the fiscal year ended October 31, 1998 of $30.6 million relating to the Pirelli settlement and associated legal fees. (12) FOREIGN SALES The Company has sales and marketing operations outside the United States in Canada, the United Kingdom, Belgium, France, Germany, Japan, Mexico and Brazil. The Company has distributor or marketing representative arrangements covering Italy, the Republic of Korea, Japan, Venezuela, Columbia and Chile. Included in revenues are export sales of approximately $117.1 million, and $213.6 million and $283.1 in fiscal years 1998, 1999 and 2000, respectively. ITEM 9.
