2 ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS. On March 29, 2001, CIENA Corporation (the "Company" or "CIENA") acquired Cyras Systems, Inc., a Delaware corporation ("Cyras"), by the statutory merger (the "Merger") of a wholly-owned subsidiary of the Company, CO Acquisition Corp., a Delaware corporation ("Sub"), with and into Cyras. The Merger was accomplished pursuant to the Agreement and Plan of Merger dated as of December 18, 2000, among the Company, Cyras and Sub (the "Merger Agreements"). The Merger occurred following the approval of the Merger Agreement by the shareholders of Cyras and satisfaction of other closing conditions. As a result of the Merger, the Company became the owner of 100% of the issued and outstanding common stock of Cyras and each outstanding share of Cyras Common stock (after conversion of Cyras's Preferred Stock, excluding Series E Preferred, into Cyras Common Stock) was converted into 0.127673316 of a share of the Company's Common Stock. Each outstanding share of Cyras Series E Preferred Stock was converted into 0.394883567 of a share of the Company's Common Stock. A total of approximately 27,882,000 shares of the Company's Common Stock will be issued to former Cyras shareholders and option holders in exchange for the acquisition by Sub of all outstanding Cyras capital stock. The offering of the shares of the Company to Cyras shareholders was registered on Form S-4 on Registration Statement No. 333-53146. Cyras stock options to purchase Cyras Common Stock were assumed by the Company and remain outstanding as options to purchase shares of the Company's Common Stock. ITEM 7.

8 CYRAS SYSTEMS, INC. (A DEVELOPMENT STAGE COMPANY) NOTES TO FINANCIAL STATEMENTS (IN THOUSANDS, EXCEPT SHARE AND PER SHARE AMOUNTS) (1) THE COMPANY The Company designs, develops and markets next generation optical networking solutions for telecommunications carriers. The Company was incorporated on July 24, 1998, under the laws of the State of California and commenced operations on that date. In November 2000, the Company reincorporated in the State of Delaware. From July 24, 1998 through December 31, 2000, the Company was considered to be in the development stage, principally engaged in research and development, raising capital and building its management team. On March 29, 2001, the Company merged with CIENA Corporation (CIENA) in a transaction to be accounted for as a purchase by CIENA, as the acquiror. The Company's stockholders, option holders and warrant holders received an aggregate total of approximately 27,882,000 shares of CIENA common stock and shares subject to options or warrants, as applicable, in the merger. (2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (a) CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS The Company considers all highly liquid investments with a purchased maturity of 90 days or less to be cash equivalents. The Company has adopted Statement of Financial Accounting Standards (SFAS) No. 115, Accounting for Certain Investments in Debt and Equity Securities. SFAS No. 115 requires entities to classify investments in debt and equity securities with readily determined fair values as "held-to-maturity," "available-for-sale," or "trading" and establishes accounting and reporting requirements for each classification. The Company has classified its investment securities as available-for-sale. Available-for-sale securities are carried at fair value, which approximates amortized cost for debt securities. Gains and losses on the sale of short-term investments are determined using the specific identification method. (b) 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. Inventories as of December 31, 2000 consisted of raw materials. (c) PROPERTY AND EQUIPMENT Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation is calculated using the straight-line method over the estimated useful lives of the equipment, generally three years. Equipment recorded under capital leases and leasehold improvements are amortized using the straight-line method over the shorter of the respective lease term or the estimated useful life of the asset, generally one and a half years to three years. (d) LONG-LIVED ASSETS The Company evaluates its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the 8

9 CYRAS SYSTEMS, INC. (A DEVELOPMENT STAGE COMPANY) NOTES TO FINANCIAL STATEMENTS -- CONTINUED (IN THOUSANDS, EXCEPT SHARE AND PER SHARE AMOUNTS) (2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- CONTINUED impairment to be recognized is measured as the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell. (e) INCOME TAXES The Company uses the asset and liability method of accounting for income taxes. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. A valuation allowance is recorded to reduce deferred tax assets to an amount whose realization is more likely than not. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the statement of operations in the period that includes the enactment date. (f) STOCK-BASED COMPENSATION The Company uses the intrinsic value-based method in accordance with Accounting Principles Board (APB) Opinion No. 25, Accounting for Stock Issued to Employees, to account for employee stock-based compensation. Accordingly, compensation cost is recorded on the date of grant to the extent the fair value of the underlying share of common stock exceeds the exercise price for a stock option or the purchase price for a share of common stock. The compensation cost is being amortized on an accelerated basis over the vesting period of the individual award consistent with the method described in Financial Accounting Standards Board (FASB) Interpretation No. 28. Pursuant to SFAS No. 123 Accounting for Stock-Based Compensation, the Company discloses the pro forma effect of using the fair value method of accounting for employee stock-based compensation arrangements. Stock based awards granted to nonemployees are accounted for pursuant to the fair value method in SFAS No. 123 and Issue No. 96-18 of the Emerging Issues Task Force. The associated expense is recognized by the Company over the period the services are performed by the nonemployee. (g) STOCK SPLIT In February 2000, the Company's stockholders approved a two-for-one common and convertible preferred stock split effective March 16, 2000. In November 2000, the Company reincorporated in the State of Delaware. In connection with the reincorporation, the Company split its common and convertible preferred stock three-for-one. Accordingly, the accompanying financial statements have been adjusted to give effect to the reincorporation and the February 2000 and November 2000 stock splits. (h) RESEARCH AND DEVELOPMENT COSTS Development costs incurred in the research and development of new products and enhancements to existing products are expensed as incurred until the product has been completed, tested, and is ready for commercial manufacturing. Hardware development projects are generally completed concurrent with the establishment of commercial manufacturing and, accordingly, to date no costs have been capitalized. Software development projects are generally completed concurrent with the establishment of technological feasibility in the form of a working model and, accordingly, to date no costs have been capitalized. 9

10 CYRAS SYSTEMS, INC. (A DEVELOPMENT STAGE COMPANY) NOTES TO FINANCIAL STATEMENTS -- CONTINUED (IN THOUSANDS, EXCEPT SHARE AND PER SHARE AMOUNTS) (2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- CONTINUED (i) FINANCIAL INSTRUMENTS AND CONCENTRATION OF CREDIT RISK The carrying value of the Company's financial instruments, consisting of cash and cash equivalents, short-term investments and long-term debt approximates fair market value. Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash and cash equivalents and short-term investments. The Company maintains the management of the majority of its cash and cash equivalents and short-term investments with three financial institutions. Investment of the funds by these institutions is governed by the Company's corporate investment policy, which aims to reduce credit risk by restricting investment to readily convertible high-grade U.S. dollar denominated investments and spreading it amongst a number of institutions. (j) CONCENTRATION OF COMPONENTS Certain key components used in the Company's products, including transponders and application specific integrated circuits, are purchased from single or limited sources. This concentration exposes the Company to risk of manufacturing delays and the possibility of lost sales. (k) USE OF ESTIMATES The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported results of operations during the reporting period. Actual results could differ from those estimates. (l) RECENT ACCOUNTING PRONOUNCEMENTS In June 1998, the Financial Accounting Standards Board issued SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities. SFAS No. 133 established accounting and reporting standards for derivative instruments, including derivative instruments embedded in other contracts, and for hedging activities. SFAS No. 133, as amended by SFAS No. 137, Deferral of the Effective Date of FASB Statement No. 133, is effective for all fiscal quarters of fiscal years beginning after June 15, 2000. The adoption of this statement has not had a material effect on the Company's financial position or results of operations. In December 1999, the Securities and Exchange Commission (SEC) issued Staff Accounting Bulletin (SAB) No. 101, Revenue Recognition, which outlines the basic criteria that must be met to recognize revenue and provides guidance for presentation of revenue and for disclosure related to revenue recognition policies in financial statements filed with the SEC. The adoption of SAB No. 101 did not have a material impact on the Company's financial position and results of operations as the Company has not had any revenue to date. In March 2000, the FASB issued Interpretation No. 44 (FIN No. 44), Accounting for Certain Transactions Involving Stock Compensation -- an Interpretation of APB 25. FIN No. 44 clarifies (i) the definition of employee for purposes of applying APB Opinion No. 25, (ii) the criteria for determining whether a plan qualifies as a noncompensatory plan, (iii) the accounting consequences of various modifications to the terms of a previously fixed stock option or award, and (iv) the accounting for an exchange of stock compensation awards in a business combination. FIN No. 44 is effective July 1, 2000, but certain conclusions in this interpretation cover specific events that occur after either December 15, 10

11 CYRAS SYSTEMS, INC. (A DEVELOPMENT STAGE COMPANY) NOTES TO FINANCIAL STATEMENTS -- CONTINUED (IN THOUSANDS, EXCEPT SHARE AND PER SHARE AMOUNTS) (2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- CONTINUED 1998, or January 12, 2000. The adoption of certain of the conclusions of FIN No. 44 covering events occurring during the period after December 15, 1998 or January 12, 2000 did not have a material effect on the Company's financial position and results of operations. The adoption of this statement did not have a material effect on the Company's financial position or results of operations. (n) RECLASSIFICATIONS Pursuant to recent guidance from the staff of the Securities and Exchange Commission, the Company has reclassified its convertible preferred stock to a separate classification outside of stockholders' deficit. (3) SHORT-TERM INVESTMENTS The following is a summary of available-for-sale securities: DECEMBER 31, ------------------ 1999 2000 ------- -------- Money market funds....................................... $37,586 $ 42,614 Commercial paper......................................... 4,985 63,465 Municipal obligations.................................... 3,000 23,687 Corporate bonds.......................................... 2,003 10,552 Government agency bonds.................................. -- 5,080 ------- -------- 47,574 145,398 Less amounts classified as cash equivalents............ 42,571 42,550 ------- -------- Securities available-for-sale....................... $ 5,003 $102,848 ======= ======== As of December 31, 1999, the aggregate amortized cost of all available-for-sale debt securities approximates the estimated fair value.

(5) INCOME TAXES The differences between the income tax expense computed at the federal statutory rate and the Company's tax provision for all periods presented primarily related to net operating losses for which no benefit has been taken. Income tax expense for the years ended December 31, 1999 and 2000, relates to state taxes.

13 CYRAS SYSTEMS, INC. (A DEVELOPMENT STAGE COMPANY) NOTES TO FINANCIAL STATEMENTS -- CONTINUED (IN THOUSANDS, EXCEPT SHARE AND PER SHARE AMOUNTS) (5) INCOME TAXES -- CONTINUED The Company has net operating loss carryforwards for federal and state income tax purposes of approximately $9,200 and $61,200 as of December 31, 1999 and 2000, respectively. In addition, the Company had federal and state research and development credit carryforwards as of December 31, 2000 of approximately $3,779 and $2,376, respectively. The Company's federal net operating loss and research and development credit carryforwards will expire in the years 2019 and 2020, respectively, if not utilized. The Company's state net operating loss carryforwards will expire in the year 2006. The state research and development credit can be carried forward indefinitely. Federal and state tax laws impose substantial restrictions on the utilization of net operating loss and tax credit carryforwards in the event of an "ownership change" as defined in Internal Revenue Code Section 382. If the Company has an ownership change, the Company's ability to utilize the above mentioned carryforwards could be significantly reduced. The Company has not yet determined whether an ownership change has occurred. (6) SUBORDINATED CONVERTIBLE NOTES In August 2000, the Company issued $150 million of 4 1/2% convertible subordinated notes due August 15, 2005. Interest is payable on February 15 and August 15 of each year, beginning February 15, 2001. The notes will be convertible to common stock upon certain qualifying events, including the initial public offering (IPO) of our common stock. In the event of an IPO, the notes are convertible to common stock at a premium to the IPO price. If an IPO has not occurred on or before March 31, 2002, the Company will be obligated to make an offer to repurchase the notes at 118.9% of the principal balance thereof on April 30, 2002. The Company is accreting the redemption premium over the period to April 30, 2002, such that the carrying value of the notes equals the redemption price at the date of the redemption obligation. Accretion of the redemption premium was $6,393 during the year ended December 31, 2000. (7) LONG-TERM DEBT On January 11, 1999, the Company entered into a loan facility agreement with a financial institution. The agreement allows for term loans in the aggregate principal amount of $3,000 and equipment loans in the aggregate principal amount of $3,000. Borrowings under the agreement are repayable in 36 equal installments of principal plus interest commencing on the individual loan inception dates, and each month thereafter, with a final balloon payment. The loan facilities bear interest at an effective rate of approximately 14% per annum, with the term loans secured by the assets of the Company and the equipment loans secured by the equipment leased. As of December 31, 1999 and 2000, the balances of the term loans are $2,499 and $1,643, respectively. As of December 31, 2000, principal payments due under the term loans in 2001 and 2002 are $976 and $667, respectively. In conjunction with the loan facility agreement, the Company issued warrants to purchase 3,600,000 shares of Series B convertible preferred stock at a price of $0.13 per share. As of December 31, 2000, the lender had not exercised the warrants. The fair value of the warrants was estimated on the date of grant using the Black-Scholes option pricing model with the following assumptions: no dividends; risk-free rate of 4.65%; volatility of 65% and contractual life of seven years. The fair value of the warrants at the date of grant was $280 and has been recorded as a discount on the term loans and capital leases. The discount is being amortized as interest expense over the life of the loans and capital leases. As of December 31, 2000, the current and long-term portion of the unamortized discount on term loans was $23 and $23, respectively. 13

In October 2000, the Company entered into a 12-year lease for a new commercial building, commencing on March 1, 2001. The base rent is $159 per month and will be increased by 4% each year over the 12-year term. In connection with the lease agreement, the Company issued warrants to purchase 25,000 shares of Series E convertible preferred stock at an exercise price of $18.47 per share. The fair value of the warrants at the date of grant was $151 and has been recorded as prepaid rent and will be expensed over the term of the lease. Additionally, the Company issued warrants to purchase 25,896 shares of Series E convertible preferred stock at an exercise price of $0.01 per share. The fair value of the warrants at the date of grant was $259 and has been recorded as prepaid rent which will be expensed over the term of the lease. The fair value of the warrants are estimated using the Black-Scholes option pricing model with the following weighted-average assumptions: no dividend yield; volatility of 85%; risk-free interest rate of 6.31% and a contractual life of five years. (9) CONVERTIBLE PREFERRED STOCK AND STOCKHOLDERS' DEFICIT (a) COMMON STOCK In connection with the formation of the Company in July 1998, the Company issued 18,000,000 shares of restricted common stock to the four founders of the Company at $0.002 per share. In August 1998, the Company repurchased 720,000 shares of common stock at the original purchase price. The founders purchased the shares in part by issuing 10-year promissory notes to the Company amounting to $19 which bear interest at 7% per annum. The notes are due and payable at the earlier of August 2009 or upon leaving the Company, and are secured by the common stock. In August 1998, the Company issued an additional 4,320,000 shares of common stock to a director at $0.004 per share. The shares vest in 14

Upon termination of employment, the Company may repurchase all unvested shares at $0.002 and $0.004 per share, respectively. As of December 31, 1999 and 2000, 12,600,000 and 7,200,000 shares were subject to repurchase, respectively. The Company maintains a right of first refusal with respect to restricted common stock. A restricted common stockholder must notify the Company prior to selling these restricted shares to a third party. Upon notification, the Company may purchase the restricted shares from the restricted common stockholder at the price offered by the third party. During the years ended December 31, 1999 and 2000, the Company received $80 and $9,596, respectively, in promissory notes from certain officers and employees in exchange for common stock. The notes are repayable over a period of five years and bear interest at 7% per annum. The notes are full recourse and are secured by the underlying common stock. (b) CONVERTIBLE PREFERRED STOCK In September 1998, the Company issued 7,200,000 shares of Series A convertible preferred stock at a price of $0.04 per share for cash proceeds of $300. In October 1998, the Company issued 70,143,996 shares of Series B convertible preferred stock at a price of $0.13 per share for cash proceeds of $8,731, net of issuance costs of $37.

In September 2000, the Company issued 270,756 shares of Series E convertible preferred stock at a price of $18.47 for cash proceeds of $4,990, net of issuance costs of $10. The rights, preferences, and privileges of the holders of Series A, B, C, D and E convertible preferred stock are as follows: - Each share of preferred stock is convertible into one share of common stock, subject to certain antidilutive adjustments, except that Series E convertible preferred stock is convertible at the lower of the issue price or 90% of a qualifying future initial public offering. Accordingly, if such a qualifying initial public offering occurs, the Company will recognize the beneficial conversion amount of approximately $556 as a deemed dividend to the Series E stockholders. - Shares of preferred stock automatically convert to common stock on the earlier of consummation of an underwritten initial public offering in which the aggregate proceeds are at least $20,000, or the date specified by written consent or agreement of at least two-thirds of the respective series shareholders. - Holders of preferred stock are entitled to dividends in preference to common shareholders at a rate of 8% of the original issue price per share per annum, if and when declared by the Company's Board of Directors. 15

(c) STOCK OPTION PLAN The 1998 Stock Plan permits the Company to grant employees, outside directors, and consultants qualified stock options, nonstatutory stock options or stock purchase rights to purchase shares of the Company's common stock. Options generally vest 25% with respect to the number granted upon the first anniversary date of the option grant and the remainder vest in equal monthly installments over the 36 months thereafter. Options are exercisable immediately. Shares issued upon exercise of non-vested stock options are subject to the Company's right to repurchase at the original exercise price. The Company's repurchase right lapses in accordance with the vesting schedule for the stock options. As of December 31, 1999 and 2000, 19,969,005 and 26,875,651 shares were subject to repurchase at a weighted-average exercise price of $0.02 and $0.44, respectively. As of December 31, 1999 and 2000, 20,407,578 and 9,940,614 shares were available for future option grants. A summary of the activity under the Company's option plan is as follows: JULY 24, 1998 (INCEPTION) THROUGH YEAR ENDED YEAR ENDED DECEMBER 31, 1998 DECEMBER 31, 1999 DECEMBER 31, 2000 ---------------------------- ------------------------------ ------------------------------ WEIGHTED-AVERAGE WEIGHTED-AVERAGE WEIGHTED-AVERAGE SHARES EXERCISE PRICE SHARES EXERCISE PRICE SHARES EXERCISE PRICE --------- ---------------- ----------- ---------------- ----------- ---------------- Outstanding at beginning of period............. -- $ -- 5,845,002 $0.01 7,057,254 $0.05 Granted................. 5,845,002 0.01 26,955,300 0.03 37,351,700 1.55 Exercised............... -- -- (24,717,048) 0.02 (24,811,428) 0.54 Forfeited............... -- -- (1,026,000) 0.02 (4,718,584) 0.59 --------- ----------- ----------- Outstanding at end of period................ 5,845,002 $0.01 7,057,254 $0.05 14,878,942 $2.82 ========= =========== =========== Weighted-average fair value of options granted during the period with exercise prices equal to fair value at date of grant................. 5,845,002 0.01 22,455,300 0.01 -- -- Weighted-average fair value of options granted during the period with exercise prices less than fair value at date of grant................. -- -- 4,500,000 0.17 37,351,700 1.55 16

Deferred stock compensation of $515 and $110,867 has been recorded during the years ended December 31, 1999 and 2000, respectively, for the excess of the fair value of the common stock underlying the options at the grant date over the exercise price of the options. These amounts are being amortized on an accelerated basis over the vesting period, generally four years, consistent with the method described in FASB Interpretation No. 28. Amortization of deferred compensation related to employee grants was $20 and $28,241 during the years ended December 31, 1999 and 2000, respectively. Had compensation cost been determined in accordance with SFAS No. 123 for all of the Company's stock-based compensation plans, net loss would have been changed to the amounts indicated below for the period from July 24, 1998 (inception) to December 31, 1998, and for the years ended December 31, 1999 and 2000: 1998 1999 2000 ----- -------- --------- Net loss: As reported.................................. $(726) $(11,727) $(108,918) Pro forma.................................... $(728) $(11,785) $(110,588) The fair value of options granted to employees are estimated on the date of grant using the minimum value method with the following weighted-average assumptions: no dividend yield; risk-free interest rate of 4.82%, 5.69% and 6.31% in 1998, 1999 and 2000, respectively; and an expected life of three years. Under the 1998 Stock Plan, the Company issued 445,002, 136,800 and 265,200 stock options to nonemployees in 1998, 1999 and 2000, respectively, in exchange for consulting services rendered. These stock options were fully vested at the date of grant. The aggregate estimated fair value of these shares and the resulting expense based on the Black-Scholes option pricing model was not material in 1998 and 1999, and $2,081 in 2000. In addition, the Company granted 960,000 and 645,000 options in 1999 and 2000, respectively, to nonemployees, which vest ratably over 24 months as services are performed. Deferred stock compensation of $493 and $7,901 has been recorded in 1999 and 2000, respectively, for the fair value of these options. Amortization of deferred stock compensation related to these nonemployee grants was $39 in 1999 and $4,666 in 2000. The fair value of the options granted to nonemployees are estimated using the Black-Scholes option pricing model with the following weighted-average assumptions: no dividend yield; volatility of 65% in 1999 and 65% to 85% in 2000; risk-free interest rate of 5.69% and 6.31% in 1999 and 17

The fair value of the unvested portion of these options is subject to adjustment based upon the future value of the Company's common stock. (d) WARRANTS In addition to the warrants issued in connection with a borrowing arrangement discussed in Note 7 and the facility lease discussed in Note 8, the Company issued to a third party, in consideration for product promotion, evaluation and feedback services to be performed, warrants to purchase 20,000 shares of common stock at an exercise price equal to the fair market value on the effective date. The warrants became vested on December 31, 2000 and the fair value of the warrants of $145 has been charged to sales and marketing expense. The fair value of the warrants are estimated using the Black-Scholes option pricing model with the following weighted-average assumptions: no dividend yield; volatility of 85%; risk-free interest rate of 6.31% and a contractual life of five years. (10) EMPLOYEE BENEFIT PLAN During the year ended December 31, 1999, the Company adopted a 401(k) Plan. The 401(k) Plan allows eligible employees to contribute up to 15% of their compensation, subject to a statutory prescribed annual limit. Employee contributions and earnings thereon vest immediately. Although the Company may make discretionary contributions to the 401(k) Plan, none have been made as of December 31, 2000. (11) SEGMENT INFORMATION SFAS No. 131, Disclosure About Segments of an Enterprise and Related Information, establishes standards for the manner in which public companies report information about operating segments, products and services, geographic areas and major customers in annual and interim financial statements. The method of determining what information to report is based on the way that management organizes the operating segments within the enterprise for making operating decisions and assessing financial performance. The Company's chief operating decision maker is considered to be the Company's Chief Executive Officer (CEO). From inception of the Company through December 31, 2000, the Company has had one product line. The CEO reviews financial information on an entity level basis for purposes of making operating decisions and assessing financial performance. The entity level financial information is the same as the information presented in the accompanying statements of operations. Accordingly, the Company has determined that it is engaged in a single operating segment. (12) SUBSEQUENT EVENTS On January 30, 2001, commercial paper with a face value of $5,300 which was purchased by the Company as a short-term investment, matured and the issuer defaulted on the obligation. The Company also owns additional commercial paper from a subsidiary of the same issuer with a face value of $4,200 due February 20, 2001. The default represents an other than temporary decline in the fair value of the investment, however, the issuer has publicly announced that it intends to make their investors whole with respect to the obligations on which they have defaulted. At this time, it is not clear whether the issuer has the financial resources to make restitution on their defaulted obligations or meet the payment obligations of future maturities of their commercial paper. The Company will be required to adjust the carrying value to the fair value in the first quarter 2001 and recognize an impairment loss estimated between $1,425 and $1,900. 18

23 NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL DATA NOTE 1 -- BASIS OF PRESENTATION On December 18, 2000, CIENA Corporation ("CIENA") entered into an agreement to merge with Cyras Systems, Inc. ("Cyras") in a transaction to be accounted for as a purchase. Cyras's stockholders, option holders and warrant holders will receive an aggregate total of 27,564,527 shares of CIENA common stock and shares subject to options or warrants, as applicable, in the merger. Assuming the acquisition was consummated on December 27, 2000, the stockholders of Cyras would have received approximately 25,167,016 shares of CIENA common stock of which an estimated 3,380,534 are restricted and subject to repurchase. Additionally, CIENA would have converted approximately 19,047,138 Cyras options and warrants into approximately 2,397,511 options and warrants to purchase CIENA common stock. Assuming the acquisition was consummated on December 27, 2000, the purchase price of the Cyras acquisition would have been approximately $1.9 billion including the estimated value of the CIENA shares and the estimated value of restricted common stock, vested and unvested options and warrants issuable upon consummation of the acquisition and estimated transaction costs of $46.5 million. These estimates are preliminary and the actual number of shares, stock options and warrants to purchase shares will depend on the actual number outstanding as of the date of consummation of the merger. The estimated value of the CIENA common stock is approximately $78.80 per share based on the average closing price of CIENA's common stock for the five-day period including the date of the announcement of the signing of the merger agreement and the two days preceding and succeeding such date. The purchase consideration is estimated as follows (in millions): Common stock................................................ $1,717.0 Assumption of Cyras options less intrinsic value of unvested options and restricted common stock....................... 151.0 Estimated transaction expenses.............................. 46.5 -------- $1,914.5 ======== The preliminary allocation of the purchase price using balances as of January 31, 2001 is summarized below (in thousands): Tangible assets............................................. $ 168,620 Deferred tax asset.......................................... 44,906 Developed technology........................................ 168,600 In-process research and development......................... 16,400 Workforce................................................... 10,400 Goodwill.................................................... 1,479,114 Deferred stock compensation................................. 255,048 Acquisition costs........................................... (46,500) Other assumed liabilities................................... (25,620) Convertible subordinated notes.............................. (156,393) ---------- Total purchase price.............................. $1,914,575 ========== The actual purchase price allocation is also dependent upon the fair values of the acquired assets and assumed liabilities as of the acquisition date and the finalization of the preliminary valuation report. For pro forma purposes the convertible subordinated notes have been reflected at Cyras's December 31, 2000 carrying value, pending a determination of their estimated fair value. The $16.4 million amount allocated to in-process research and development represents the purchased in-process technology for projects that, as of the date of the acquisition, had not yet reached technological feasibility and had no alternative future 23

24 NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL DATA -- (CONTINUED) use. Based on preliminary assessments, the value of these projects was determined by estimating the resulting net cash flows from the sale of the products resulting from the completion of the projects, reduced by the portion of the revenue attributable to developed technology and the percentage of completion of the project. The resulting cash flows were then discounted back to their present value at appropriate discount rates. The nature of the efforts to develop the purchased in-process research and development into commercially viable products principally relates to the completion of all planning, designing, prototyping and testing activities that are necessary to establish that the product can be produced to meet its design specification including function, features and technical performance requirements. The resulting net cash flows from such products are based on estimates of revenue, cost of revenue, research and development costs, sales and marketing costs, and income taxes from such projects. The amounts allocated to in-process research and development will be charged to the statements of operations in the period the acquisition is consummated. NOTE 2 -- PRO FORMA ADJUSTMENTS: A To reflect acquisition of Cyras based on the preliminary purchase price allocation described in Note 1. B To reflect amortization of developed technology, goodwill and workforce over their estimated useful lives of seven, seven and three years respectively, as if the acquisition occurred on November 1, 1999. The $16.4 million amount allocated to in-process research and development has not been included in the unaudited pro forma combined statement of operations as it is nonrecurring, but is included in the unaudited pro forma combined balance sheet. This amount will be expensed in the period the acquisition is consummated. C To eliminate historical deferred stock compensation and related amortization charges for Cyras stock option grants and record deferred stock compensation in accordance with FIN 44, "Accounting for Certain Transactions Involving Stock Compensation -- an interpretation of APB 25," related to Cyras unvested stock options and restricted common stock assuming a consummation date of December 27, 2000. D To record pro forma combined provision for income taxes at a rate of 33.5% of income before taxes adjusted for permanent differences including amortization of intangible assets. 24
