NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(unaudited)

  1.   The Company and Basis of Presentation:

     The accompanying unaudited condensed consolidated financial statements have been prepared by F5 Networks, Inc. (“F5”) in accordance with the rules and regulations of the Securities and Exchange Commission for interim financial statements. Accordingly, certain information and footnote disclosures, normally included in consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States, have been condensed or omitted pursuant to such rules and regulations. In the opinion of management of the Company, the unaudited condensed consolidated financial statements reflect all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the Company’s financial position at June 30, 2001, its operating results for the three and nine months ended June 30, 2001 and 2000 and cash flows for the nine months ended June 30, 2001 and 2000. The condensed consolidated balance sheet at September 30, 2000 has been derived from audited financial statements as of that date. These consolidated financial statements and the notes should be read in conjunction with the Company’s consolidated financial statements and notes thereto contained in the Company’s annual report on Form 10-K filed with the Securities and Exchange Commission on December 13, 2000.

  2.   Summary of Significant Accounting Policies:

Principles of Consolidation

     The financial statements consolidate the accounts of F5 Networks, Inc. and its wholly owned subsidiaries F5 Networks, Ltd., F5 Networks, Singapore Pte. Ltd. and F5 Networks, Japan K.K. and are collectively hereinafter referred to as the “Company”. All intercompany transactions have been eliminated.

Reclassifications

     Certain reclassifications to historical amounts within the consolidated financial statements have been made to conform with current year presentations. Such reclassifications did not impact historical net income (loss) or cash flows.

Use of Estimates

     The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Revenue Recognition

     The Company recognizes software revenue under Statement of Position 97-2, “Software Revenue Recognition,” and SOP 98-9 “Modification of SOP 97-2, Software Revenue Recognition, with Respect to Certain Transactions.”

     The Company sells products through resellers, original equipment manufacturers and other channel partners, as well as to end users, under similar terms. The Company generally combines software license, hardware, installation and customer support elements into a package with a single “bundled” price. The Company allocates a portion of the sales price to each element of the bundled package based on their respective fair values when the individual elements are sold separately. Revenues from the license of software, net of an allowance for estimated returns, are recognized when the product has been shipped and the customer is obligated to pay for the product.

Table of Contents

Installation revenue is recognized when the product has been installed at the customer’s site. Revenues for customer support are recognized on a straight-line basis over the service contract terms. Estimated sales returns are based on historical experience by product and are recorded at the time revenues are recognized.

Cash Equivalents and Short-Term Investments

     Cash equivalents are highly liquid investments, consisting of investments in money market funds and marketable securities which are readily convertible to cash and subject to insignificant risk of changes in value. The Company’s cash and cash equivalents balance consists of the following:

                 
    June 30,   September 30,
    2001   2000
   
 
    (in thousands)
Cash
  $ 44,883     $ 18,354  
Short-term investments
    23,714       34,663  
 
   
     
 
 
  $ 68,597     $ 53,017  
 
   
     
 

Concentration of Credit Risk

     The Company places its temporary cash investments with major financial institutions. As of June 30, 2001, all of the Company’s temporary cash investments were placed with five institutions.

     The Company’s customers are from diverse industries and geographic locations. The majority of net revenues from international customers are denominated in U.S. dollars and were approximately $9.6 million for the three months ended June 30, 2001, and $5.9 million for the three months ended June 30, 2000. For the nine months ended June 30, 2001 and 2000, one customer accounted for 9% and 17% of net revenues, respectively. One customer accounted for 8% and 6% of the Company’s accounts receivable balance at June 30, 2001 and 2000, respectively. A single customer accounted for 8% and 13% of the Company’s net revenues for the three months ended June 30, 2001 and June 30, 2000, respectively.

Inventories

     Inventories consist of hardware, software and related component parts and are recorded at the lower of cost or market (as determined by the first-in, first-out method).

     Inventories are comprised of the following:

                 
    June 30,   September 30,
    2001   2000
   
 
    (in thousands)
Finished goods
  $ 5,230     $ 2,045  
Raw materials
    2,210       3,186  
Less: Provision for excess of inventory
    (3,276 )      
 
   
     
 
 
  $ 4,164     $ 5,231  
 
   
     
 

     Due to changes in current market conditions and a revision of our sales forecast, a review was made of our inventory needs and an assessment of our future purchase commitments as of March 31, 2001. As a result, we determined a provision for excess inventory and future purchase commitments would be recorded. The provision for excess inventory was charged to cost of revenues in the amount of $3.8 million for the nine months ended June 30, 2001, which consisted of a $3.0 million inventory valuation allowance and $800,000 of future purchase commitments. An additional $1.1 million was included in the provision for excess inventory in the statement of operations. The charge is associated with changes in the configuration of our EDGE-FX Cache product, which will increase the functionality of the product. These costs are associated with updating both existing inventory and product previously sold to customers, as well as costs to fulfill existing purchase commitments and have been

included in cost of revenues for the nine months ended June 30, 2001. During the quarter ended June 30, 2001 the provision for excess inventory increased by $236,000 due to the receipt of fully reserved, prepaid inventory. As of June 30, 2001 no amount of the reserve has been utilized.

Comprehensive Income (Loss)

     The following table sets forth a reconciliation of net income (loss) to comprehensive income (loss), net of tax:

                                 
    Three months ended   Nine months ended
    June 30,   June 30,
   
 
    2001   2000   2001   2000

Comprehensive income (loss)
  $ (1,555 )   $ 3,560     $ (18,877 )   $ 12,029  
 
 
   
 
 

Net Income (Loss) Per Share

     Basic net income (loss) per share is computed by dividing net income (loss) by the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share is computed by dividing net income (loss) by the weighted average number of common and dilutive common stock equivalent shares outstanding during the period. The Company excludes the impact of dilutive common stock equivalent shares from the calculation of diluted net income (loss) per share when the inclusion of such elements would be antidilutive.

     The following table sets forth the computation of basic and diluted net income (loss) per share for the three and nine months ended June 30, 2001 and 2000:

                                   
      Three months ended   Nine months ended

Restructuring Charge

     During the first fiscal quarter of 2001, we recorded a restructuring charge of $1.1 million in connection with management’s decision to bring operating expenses in line with the business revenue growth model. As a result of

8


Table of Contents

changes in the business revenue growth model, the Company terminated 96 employees throughout all divisions of the Company. In January 2001, all identified employees had been terminated. During the quarter ended March 31, 2001, we reversed $96,000 of the original accrual due to a revision of previous estimates. As of March 31, 2001, substantially all of the restructuring charge accrued during the first fiscal quarter of 2001 had been paid.

Recent Accounting Pronouncements

     In June 1998, the FASB issued Statement of Financial Accounting Standards No. 133, “Accounting for Derivative Instruments and Hedging Activities.” This statement requires that all derivative instruments be recorded on the balance sheet at their fair value. Changes in the fair value of derivatives are recorded each period in current earnings or other comprehensive income, depending on whether a derivative is designated as part of a hedge transaction and, if it is, the type of hedge transaction. In July 1999, the FASB issued SFAS No. 137, “Accounting for Derivative Instruments and Hedging Activities Deferral of the Effective Date of FASB Statement No. 133.” SFAS No. 137 deferred the effective date of SFAS No. 133 until fiscal years beginning after June 15, 2000. The Company does not use derivative instruments, therefore the adoption of this statement will not have any effect on the Company’s results of operations or its financial position.

     In December 1999, SEC Staff Accounting Bulletin No. 101 (“SAB 101”), “Revenue Recognition in Financial Statements,” was issued. This pronouncement summarizes certain of the SEC staff’s views in applying generally accepted accounting principles to revenue recognition. SAB 101 is required to be adopted by the Company for the year ended September 30, 2001. The Company implemented SAB 101 in the first quarter of the fiscal year 2001 and there was no material impact on the Company’s financial statements.

     In July of 2001 the Financial Accounting Standards Board issued Statement of Financial Accounting Standard No. 141 “Business Combinations” (SFAS No. 141) which is effective for all business combinations initiated after July 1, 2001. SFAS No. 141, supersedes APB Opinion No. 16, Business Combinations, and FASB Statement No. 38, Accounting for Preacquisition Contingencies of Purchased Enterprises and requires that all business combinations be accounted for using the purchase method of accounting. Further, SFAS No. 141 requires certain intangibles to be recognized as assets apart from goodwill if they meet certain criteria and also requires expanded disclosures regarding the primary reasons for consummation of the combination and the allocation of the purchase price paid to the assets acquired and liabilities assumed by major balance sheet caption. The Company is currently in the process of assessing the impact of this statement on the financial position of the Company.

     In July of 2001, the Financial Accounting Standards Board issued Statement of Financial Accounting Standard No. 142 “Goodwill and Other Intangible Assets” (SFAS No. 142) which is effective for fiscal years beginning after December 15, 2001. SFAS No. 142 supercedes APB Opinion No. 17, Intangible Assets, and addresses financial accounting and reporting for intangible assets acquired individually or with a group of other assets and the accounting and reporting for goodwill and other intangible assets subsequent to their acquisition. Under the model set forth in SFAS No. 142, goodwill is no longer amortized to earnings, but instead be subject to periodic testing for impairment. The Company is currently in the process of assessing the impact of this statement on the financial position of the Company.

  3.   Sale of Common Stock to Nokia

     On June 26, 2001, we entered into a Common Stock and Warrant Purchase Agreement with Nokia Finance International B.V. (“NFI”). Under this Agreement, we issued and sold to NFI (i) 2,466,421 shares of Common Stock and (ii) warrants (the “Warrants”) to purchase additional shares of Common Stock. We received total proceeds of $34.9 million, net of $1.8 million in estimated issuance costs from the sale of these shares and the Warrants. The Warrants allow NFI to purchase additional shares of Common Stock to increase its ownership percentage in the Company (up to a maximum of one share less than 20%) during three ten business day periods beginning on December 31, 2001, June 30, 2002 and December 31, 2002, at an exercise price equal to the average 10-day closing price before the start of each period. As a condition to closing the Agreement, the Company appointed a nominee of NFI to its Board of Directors. As part of this transaction, the Company and NFI also entered into an OEM Software License Agreement and a Technology Development Agreement.

     In addition, the Company and NFI entered into an Investor’s Rights Agreement that governs the relationship between the Company and NFI. Among other things, this agreement grants to NFI certain preemptive and registration rights, as well as the right to nominate a representative to the Company’s Board of Directors. The Investor’s Rights Agreement will terminate on the latest of (i) the second anniversary of the Investor’s Rights Agreement, (ii) the termination of the OEM Agreement, or (iii) the termination of the Technology Agreement.

     We recorded the issuance of the Common Stock and Warrants by allocating the net proceeds to the Common Stock and the Warrants, based upon their relative fair values at the date of issuance. The fair value allocated to the Warrants was $1.7 million based on an independent valuation. Based upon the relative fair value at the date of issuance, the amount of net proceeds allocated to the Warrants, and included as a component of common stock, was $1.6 million. The amount allocated to the Common Stock was $33.4 million.

     NFI has also signed a two-year OEM license and reseller agreement that gives them access to all of F5’s iTCM products. Beginning immediately, Nokia may resell all of our products and integrate our software as part of its market-leading network security solutions, including its firewall and VPN (Virtual Private Network) product families.

     In addition, over the next several months, F5 and NFI will define and pursue a number of joint technology development projects, beginning with the integration between F5’s iTCM software and NFI’s current products, such as its Network Management System (NMS.) Other joint development initiatives may encompass wireless CDNs (Content Deliver Networks) and carrier class Internet Traffic Management devices.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations .

      The following Management’s Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with our Financial Statements and Notes. Our discussion contains forward-looking statements based upon current expectations. These forward-looking statements include, but are not limited to, statements about our plans, objectives, expectations and intentions and other statements that are not historical facts. Because these forward-looking statements involve risks and uncertainties, our actual results and the timing of certain events could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including those set forth under “Risk Factors” and “Business” in the Company’s Form 10-K for the fiscal year ended September 30, 2000, and elsewhere in this report.

Overview

     F5 Networks, Inc. (“F5”) is a leading provider of integrated Internet traffic and content management solutions designed to improve the availability and performance of Internet-based servers and applications. Our Internet traffic products monitor and manage local and geographically dispersed servers and intelligently direct traffic to the server best able to handle a user’s request. Our content management products enable network managers to increase access to content by capturing and storing it at points between production servers and end-users and ensure that newly published or updated files and applications are replicated uniformly across all target servers. When combined with our network management tools, these products help organizations optimize their network server availability and performance and cost-effectively manage their Internet infrastructure.

     Currently, we derive approximately 55.8% of our net revenues from sales of BIG-IP, and we expect to derive a significant portion of our net revenues from sales of BIG-IP in the future. For the three months ended June 30, 2001, no individual customer represented more than 10% of our total revenues.

     Net revenues derived from customers located outside of the United States were $9.6 million and $5.9 million for the three months ended June 30, 2001 and 2000, respectively. We plan to continue expanding our international operations, primarily in the European and the Asia Pacific markets, because we believe international markets represent significant growth opportunity.

     Customers who purchase our products have the option to receive installation services and an initial customer support contract, typically covering a 12-month period. We generally combine the software license, installation, and customer support elements of our products into a package with a single price. We allocate a portion of the sales price to each element of the bundled package based on their respective fair values as determined when the individual elements are sold separately. Customers may also purchase consulting services, training and renew their initial customer support contract.

     Revenues from the sale of our products and software licenses are recognized when the product has been shipped and the reseller or end user is obligated to pay for the product. Services revenue for installation is recognized when the product has been installed at the customer’s site. Revenues for customer support are recognized on a straight-line basis over the service contract term. Consulting services are customarily billed at fixed rates, plus out-of-pocket expenses, and revenues are recognized when the consulting has been completed. Training revenue is recognized when the training has been completed. Estimated sales returns are based on historical experience by product and are recorded at the time revenues are recognized.

     Our ordinary payment terms to our domestic customers are net 30 days. Our ordinary payment terms to our international customers are net 60 days. We have offered extended payment terms beyond ordinary terms to some customers. For these arrangements, revenue is generally recognized ratably over the terms of the arrangement.

     In view of the rapidly changing nature of our business, our limited operating history and the current economic conditions, we believe that period-to-period comparisons of net revenues and operating results are not necessarily meaningful and should not be relied upon as indicators of future performance. To achieve profitability we will need to increase our net revenues and manage operating expenses.

     On June 26, 2001, we entered into a Common Stock and Warrant Purchase Agreement with Nokia Finance International B.V. (“NFI”). Under this Agreement, we issued and sold to NFI (i) 2,466,421 shares of Common Stock and (ii) warrants (the “Warrants”) to purchase additional shares of Common Stock. We received total proceeds of $34.9 million, net of $1.8 million in estimated issuance costs from the sale of these shares and the Warrants. The Warrants allow NFI to purchase additional shares of Common Stock to increase its ownership percentage in the Company (up to a maximum of one share less than 20%) during three ten business day periods beginning on December 31, 2001, June 30, 2002 and December 31, 2002, at an exercise price equal to the average 10-day closing price before the start of each period.

     We recorded the issuance of the Common Stock and Warrants by allocating the net proceeds to the Common Stock and the Warrants, based upon their relative fair values at the date of issuance. The fair value allocated to the Warrants was $1.7 million based on an independent valuation. Based upon the relative fair value at the date of issuance, the amount of net proceeds allocated to the Warrants and included as a component of common stock was $1.6 million. The amount allocated to the Common Stock was $33.4 million.

     NFI has also signed a two-year OEM license and reseller agreement that gives them access to all of F5’s iTCM products. Beginning immediately, Nokia may resell all of our products and integrate our software as part of its market-leading network security solutions, including its firewall and VPN (Virtual Private Network) product families.

     In addition, over the next several months, F5 and NFI will define and pursue a number of joint technology development projects, beginning with the integration between F5’s iTCM software and NFI’s current products, such as its Network Management System (NMS.) Other joint development initiatives may encompass wireless CDNs (Content Deliver Networks) and carrier class Internet Traffic Management devices.

     We have recorded a total of $8.3 million of stock compensation costs since our inception through June 30, 2001. These charges represent the difference between the exercise price and the deemed fair value of certain stock options granted to our employees and outside directors. These options generally vest ratably over a four-year period. We are amortizing these costs using an accelerated method as prescribed by FASB interpretation No. 28 (“FIN No. 28”) and have recorded stock compensation charges of $2.1 million, $2.5 million and $420,000 for the years ended

11


Table of Contents

September 30, 2000, 1999 and 1998, respectively and $245,000 and $ 434,000 for the three months ended June 30, 2001 and 2000 respectively.

     We expect to recognize amortization expense related to unearned compensation of approximately $2.6 million, $400,000, $60,000 and $0 during the years ended September 30, 2001, 2002, 2003 and 2004, respectively. We cannot guarantee, however, that we will not accrue additional stock compensation costs in the future or that our current estimate of these costs will prove accurate.

Net Revenues:

     Net revenues consist of sales of our products, which include software licenses, and services. Services include revenue from installation, service and support agreements provided as part of the initial product sale, sales of extended service and support contracts, consulting services, and training.

      Product revenues . Product revenues decreased by 10.6% from $23.8 million for the three months ended June 30, 2000 to $21.3 million for the three months ended June 30, 2001. Product revenues increased 0.3% from $58.6 million for the nine months ended June 30, 2000 to $58.8 million for the nine months ended June 30, 2001. The decrease in the quarterly comparative product revenues was due primarily to a decrease in the quantity of product sold in the North American market.

      Service revenues . Service revenues increased by 43.0% from $5.4 million for the three months ended June 30, 2000 to $7.7 million for the three months ended June 30, 2001. Service revenues increased 64.8% from $13.4 million for the nine months ended June 30, 2000 to $22.0 million for the nine months ended June 30, 2001. The

12


Table of Contents

increase was due primarily to an increase in the installed base of our products and the renewal of service and support contracts.

     International revenues represented 33% and 20% of net revenues for the three months ended June 30, 2001 and 2000, respectively. International revenues represented 32% and 17% for the nine months ended June 30, 2001 and 2000. We expect international sales will continue to represent a significant portion of net revenues, although we cannot assure you that international sales as a percentage of net revenues will remain at current levels.

     In the future our average selling prices may decrease primarily as a result of a shift in our channel mix and, to a lesser extent, increased competition. This decrease may have a negative impact on our gross margin. In addition, certain of the third-party components, included in our products, are subject to significant price changes based on market supply and demand and may significantly increase in price in the future. Due to limited supply, any such increase may also have a negative impacet on our gross margin.

      Cost of Net Revenues:

     Cost of net revenues consists primarily of hardware components, finished products, fees for third-party software products integrated into our products, service and support personnel, and allocation of our facilities and depreciation expenses.

      Cost of product revenues . Cost of product revenues increased by 27.7%, from $6.0 million for the three months ended June 30, 2000 to $7.7 million for the three months ended June 30, 2001 and increased as a percentage of net revenues from 20.6% to 26.6% for the same periods. Cost of product revenues increased by 49.9% from $15.7 million for the nine months ended June 30, 2000 to $23.5 million for the nine months ended June 30, 2001 and increased as a percentage of net revenues from 21.8% to 29.1% for the same periods. The increases as a percentage of net revenues were due to component enhancements of our products and a decrease in our average selling price as a result of a change in our channel mix.

      Cost of service revenues . Cost of service revenues increased by 29.9%, from $2.2 million for the three months ended June 30, 2000 to $2.9 million for the three months ended June 30, 2001 and increased as a percentage of net revenues from 7.7% to 10.0% for the same periods. Cost of service revenues increased by 91.2% from $5.1 million for the nine months ended June 30, 2000 to $9.7 million for the nine months ended June 30, 2001 and increased as a percentage of net revenues from 7.1% to 12.0% for the same periods. These increases were due to increased personnel from 82 at June 30, 2000 to 90 at June 30, 2001, and the related costs.

      Provision for excess inventory. Due to changes in current market conditions and a revision of our sales forecast, a review was made of our inventory needs and an assessment of our future purchase commitments as of March 31, 2001. As a result, we determined a provision for excess inventory and future purchase commitments would be recorded. The provision for excess inventory was charged to cost of revenues in the amount of $3.8 million for the nine months ended June 30, 2001 which consisted of a $3.0 million inventory valuation allowance and $800,000 of future purchase commitments. An additional $1.1 million was included in the provision for excess inventory in the statement of operations. The charge is associated with changes in the configuration of our EDGE-FX Cache product, which will increase the functionality of the product. These costs are associated with updating both existing inventory and product previously sold to customers, as well as costs to fulfill existing purchase commitments and have been included in cost of revenues for the nine months ended June 30, 2001. During the quarter ended June 30, 2001 the provision for excess inventory increased $236,000 due to the receipt of fully reserved, prepaid inventory. As of June 30, 2001 no amount of the reserve has been utilized.

      Sales and marketing . Our sales and marketing expenses consist primarily of salaries, commissions and related benefits of our sales and marketing staff, costs of our marketing programs, including public relations, advertising and trade shows and an allocation of our facilities and depreciation expenses. Sales and marketing expenses increased by 16.4%, from $10.6 million for the three months ended June 30, 2000 to $12.3 million for the three months ended June 30, 2001. Sales and marketing expenses increased by 55.4% from $24.8 million for the nine months ended June 30, 2000 to $38.5 million for the nine months ended June 30, 2001. These increases were due to an increase in sales and marketing and professional services personnel from 115 to 213, increased

13


Table of Contents

commissions, and increased advertising and promotional activities.

      Research and development . Our research and development expenses consist primarily of salaries and related benefits for our product development personnel and an allocation of our facilities and depreciation expenses. Research and development expenses increased by 24.0%, from $3.4 million for the three months ended June 30, 2000 to $4.2 million for the three months ended June 30, 2001. Research and development expenses increased by 61.0% from $8.4 million for the nine months ended June 30, 2000 to $13.5 million for the nine months ended June 30, 2001. These increases were due primarily to an increase in product development personnel from 101 to 123, from June 30, 2000 to June 30, 2001. Our future success is dependent in a large part on the continued enhancement of our current products and our ability to develop new, technologically advanced products that meet the sophisticated needs of our customers. We expect research and development expenses to increase in future periods.

      General and administrative . Our general and administrative expenses consist primarily of salaries, benefits and related costs of our executive, finance, information technology, human resource and legal personnel, third-party professional service fees, and an allocation of our facilities and depreciation expenses. General and administrative expenses increased by 41.2% from $2.2 million for the three months ended June 30, 2000 to $3.1 million for the three months ended June 30, 2001. General and administrative expenses increased by 119.6% from $5.4 million for the nine months ended June 30, 2000 to $12.0 million for the nine months ended June 30, 2001. These increases were due primarily to an increase in general and administrative personnel from 54 to 69 from June 30, 2000 to June 30, 2001.

      Restructuring charge. During the first fiscal quarter of 2001, we recorded a restructuring charge of $1.1 million in connection with management’s decision to bring operating expenses in line with the business revenue growth model. As a result of change in the business revenue growth model, the Company terminated 96 employees throughout all divisions of the Company. In January 2001, all identified employees had been terminated. During the quarter ended March 31, 2001, we reversed $96,000 of the original accrual due to a revision of previous estimates. As of March 31, 2001, substantially all of the restructuring charge accrued during the first fiscal quarter of 2001, had been paid.

      Stock compensation . We recorded stock compensation charges of $245,000 for the three months ended June 30, 2001 and $434,000 for the three months ended June 30, 2000. For the nine months ended June 30, 2001 and 2000, stock compensation was $2.4 million and $1.4 million, respectively.

      Other income, net. Other income consists primarily of earnings on our cash and cash equivalent balances. Other income, net was $855,000 for the three months ended June 30, 2000 and $562,000 for the three months ended June 30, 2001. The decrease in other income is due to a decline in our cash and cash equivalent balances which were used for the investment in the building of our corporate facilities and our global business. For the nine months ended June 30, 2000 and 2001, other income, net, was $2.4 million and $1.4 million, respectively.

      Income taxes . At June 30, 2001 the Company had net operating loss carryforwards of approximately $10.4 million, which begin to expire in 2011. During the quarter ended June 30, 2001, the Company changed its effective annual income tax rate from an income tax benefit of 21% to an income tax benefit of 17% based upon a review of the Company’s forecasts and expected permanent and temporary differences for fiscal year 2000. This change in the effective annual income tax rate resulted in income tax expense of approximately $0.6 million for three months ended June 30, 2001.

Liquidity and Capital Resources

     Cash and cash equivalents, short-term investments, and restricted cash increased from $53.0 million at September 30, 2000 to $68.6 million at June 30, 2001, an increase of $15.6 million. This increase is primarily due to the sale on June 26, 2001 of approximately 2.5 million shares of common stock to Nokia Finance International for net proceeds of $34.9 million. Inventory management remains an area of focus as we balance the need to maintain strategic inventory levels to ensure competitive lead times. Any such increases in inventory can be expected to reduce cash and cash equivalents, and short-term investments. In the future we may also require a larger inventory of

14


Table of Contents

products in order to provide better availability to customers and achieve purchasing efficiencies. Any such increase can be expected to reduce cash, cash equivalents and short-term investments.

     Cash used in investing activities was $8.2 million for the nine months ended June 30, 2001, and $10.9 million for the nine months ended June 30, 2000. The decrease in investing activities was primarily the result of capital expenditures associated with the completion of the new corporate facilities incurred in fiscal year 2000.

     As of June 30, 2001, our principal commitments consisted of obligations outstanding under operating leases. In April 2000, we entered into a lease agreement on two buildings for a new corporate headquarters. The lease commenced in July 2000 on the first building; and the lease on the second building commenced in October 2000. The lease for both buildings expires in 2012 with an option for renewal. We established a restricted escrow account in connection with this lease agreement. Under the term of the lease, a $6 million irrevocable standby letter of credit is required through November 2012, unless the lease is terminated before then. This amount has been included on our balance sheet as of June 30, 2001 as a component of restricted cash. In April 2001, we signed an agreement to sublease the second building. The sublease will substantially cover our monthly costs as the primary tenant.

     We expect that our existing cash balances and cash from operations will be sufficient to meet our anticipated working capital and capital expenditures for the foreseeable future.

Item 3. Quantitative and Qualitative Disclosure About Market Risk.

      Interest Rate Risk. We currently do not hold derivative financial instruments or equity securities in our investment portfolio. The Board of Directors has authorized the Company to trade in publicly traded company options. Our cash equivalents consist of high-quality securities, as specified in our investment policy guidelines. The policy limits the amount of credit exposure to any one issue or issuer to a maximum of 20% of the total portfolio with the exception of treasury securities, commercial paper and money market funds, which are exempt from size limitation. The policy limits all short-term investments to mature in two years or less, with the average maturity being one year or less. These securities are subject to interest rate risk and will decrease in value if interest rates increase.

      Foreign Currency Risk. The majority of our sales and expenses are denominated in U.S. dollars and as a result, we have not experienced significant foreign exchange gains and losses to date. While we have conducted some transactions in foreign currencies during the fiscal year ended September 30, 2000 and the nine months ended June 30, 2001 and expect to continue to do so, we do not anticipate that foreign exchange gains and losses will be significant. We have not engaged in foreign currency hedging to date, however we may do so in the future.

The Company hereby represents and warrants that all shares of Warrant Stock which may be issued upon the exercise of this Warrant will, upon such exercise, be duly and validly authorized and issued, fully paid and nonassessable and free from all taxes, liens and charges in respect of the issuance thereof. The Company agrees that the shares so issued shall be and be deemed to be issued to such Holder as the record owner of such shares as of the close of business on the date on which this Warrant shall have been surrendered for exercise in accordance with the terms hereof. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Warrant.

The Company shall maintain at the above-mentioned office or agency a registry showing the name and address of the registered Holder of this Warrant. This Warrant may be surrendered for exchange, transfer or exercise, in accordance with its terms, at such office or agency of the Company, and the Company shall be entitled to rely in all respects, prior to written notice to the contrary, upon such registry.

-3-

9. CHANGE-IN-CONTROL TRANSACTION. If at any time, while this Warrant, or any portion thereof, is outstanding and unexpired, a Change-in-Control Transaction (as defined below) shall be initiated, this Warrant shall become fully-vested and exercisable immediately prior to the Change-in-Control Transaction, and lawful provision shall be made so that the Holder shall thereafter be entitled to receive upon exercise of this Warrant upon payment of the Exercise Price in effect based on the Average Trading Price on the trading day prior to the first public announcement of the Change-in-Control Transaction, up to either (i) that number of shares necessary to increase the Holding Group's interest in the Company to one share less than 20% of the Company's outstanding Common Stock on the date of exercise (after giving effect to any issuance of shares in connection with the Change-in-Control Transaction); or (ii) the equivalent number of shares of stock or other securities or property of the successor corporation resulting from such Change-in-Control Transaction (after giving effect to the exchange ratio or other consideration methodology applied in such Change-in-Control Transaction). A "Change-in-Control Transaction" means (a) any agreement to which the Company is a party calling for the merger or consolidation of the Company or the sale of all or a substantial portion of the assets of the Company; (b) any acquisition by any third party of beneficial ownership of 50% or more of the outstanding Common Stock of the Company; or (c) any public announcement of a tender or exchange offer for 50% or more of the outstanding Common Stock of the Company.

In the event this Warrant is not exercised within 10 Business Days after the consummation of the Change-in-Control Transaction, this Warrant shall terminate.

10. SUBDIVISION, COMBINATION, RECLASSIFICATION, ETC. If the Company at any time shall, by subdivision, combination, reclassification of securities or otherwise, change the Warrant Stock into the same or a different number of securities of any class or classes, this Warrant shall thereafter entitle the holder to acquire such number and kind of securities as would have been issuable in respect of the Warrant Stock (or other securities which were subject to the purchase rights under this Warrant immediately prior to such subdivision, combination, reclassification or other change) as the result of such change if this Warrant had been exercised in full for cash immediately prior to such change. The Exercise Price per share of the Warrant Stock shall be adjusted if and to the extent necessary to reflect such change. In the event that, on or after the first trading day included in the calculation of Average Closing Price in respect of any Exercise Period and on or prior to the date of exercise of the Warrant during such Exercise Period, there shall have occurred (i) any dividend or distribution of assets (whether in the form of cash, securities, property or any other assets, or any rights to acquire any of such) other than a normal quarterly cash dividend consistent with past practice, or (ii) any issue or sale to holders of Common Stock generally of any such assets or of shares of capital stock of the Company without consideration or for a consideration less than the fair market value thereof (which in the case of Common Stock will be deemed to be the applicable Average Closing Price), the Exercise Price per share shall be appropriately reduced to reflect the impact of such dividend, distribution, issue or sale. Similarly, in the event that, on or after the first trading day included in the calculation of Average Closing Price in respect of any Exercise Period and on or prior to the date of exercise of the Warrant during such Exercise Period, there shall have occurred reverse stock-split or similar combination of the Common Stock, the Exercise Price per share shall be appropriately increased to reflect the impact of such reverse stock-split or combination. The Company shall give the

They may not be sold, offered for sale, pledged, hypothecated or otherwise transferred in the absence of a registration statement in effect with respect to the securities under the Act or an opinion of counsel reasonably satisfactory to the company that such registration is not required, or unless sold pursuant to an exemption to the Act."

12. REPRESENTATIONS, WARRANTIES AND COVENANTS. The Company hereby represents, warrants and covenants to the Holder hereof that:

(a) during the period this Warrant is outstanding, the Company will reserve from its authorized and unissued Common Stock a sufficient number of its duly authorized but unissued shares of Common Stock to provide for the issuance of shares of Common Stock issuable upon exercise of this Warrant in full;

(b) the issuance of this Warrant shall constitute full authority to the Company's officers who are charged with the duty of executing stock certificates to execute and issue the necessary certificates for the shares of Warrant Stock issuable upon exercise of this Warrant;

13. COOPERATION. The Company will not, by amendment of its Articles or through any reorganization, recapitalization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company, but will at all times in good faith assist in the carrying out of all the provisions of this Warrant and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the Holder of the Warrant against impairment.

14. LOST, STOLEN, MUTILATED OR DESTROYED WARRANT. If this Warrant is lost, stolen, mutilated or destroyed, the Company may, on reasonable terms as to indemnity or otherwise (which shall, in the case of a mutilated Warrant, include the surrender thereof), issue a new Warrant of like denomination and tenor as, and in substitution for, this Warrant.

15. SUCCESSORS AND ASSIGNS. The terms and provisions of this Warrant shall inure to the benefit of, and be binding upon, the Company and the Holders hereof and their respective successors and assigns.

NOW, THEREFORE, THE PARTIES HEREBY AGREE AS FOLLOWS:

1. REGISTRATION RIGHTS. The Company covenants and agrees as follows:

1.1 DEFINITIONS. For purposes of this Agreement:

(a) The term "Securities Act" means the Securities Act of 1933, as amended.

(b) The term "Change-in-Control Transaction" means (a) any agreement to which the Company is a party calling for the merger or consolidation of the Company or the sale of all or a substantial portion of the assets of the Company; (b) any acquisition by any third party of beneficial ownership of 50% or more of the outstanding Common Stock of the Company; or (c) any public announcement of a tender or exchange offer for 50% or more of the outstanding Common Stock of the Company.

(c) The term "Form S-3" means such form under the Securities Act as in effect on the date hereof, any successor registration form or any other registration form under the Securities Act subsequently adopted by the SEC that permits inclusion or incorporation of substantial information by reference to other documents filed by the Company with the SEC.

(d) The term "Holder" means the Investor and any other person owning or having the right to acquire Registrable Securities or any assignee thereof in accordance with Section 1.11 hereof;

(e) The term "Exchange Act" means the Securities Exchange Act of 1934, as amended.


(f) The term "register," "registered," and "registration" refer to a registration effected by preparing and filing a registration statement or similar document in compliance with the Securities Act, and the declaration or ordering of effectiveness of such registration statement or document.

(g) The term "Registrable Securities" means (i) the Common Stock originally issued under the Purchase Agreement, (ii) the Common Stock issued upon exercise of the Warrant (as defined in the Purchase Agreement) and (iii) any Common Stock of the Company issued as (or issuable upon the conversion or exercise of any warrant, right or other security that is issued as) a dividend or other distribution with respect to, or in exchange for, or in replacement of, the shares referenced in (i) and (ii) above, excluding in all cases, however, any Registrable Securities sold by the Investor in a transaction in which its rights under this Section 1 are not assigned; and the number of shares of "Registrable Securities" outstanding at any time, shall be determined by the number of shares of Common Stock outstanding that are, and the number of shares of Common Stock issuable pursuant to then exercisable or convertible securities that are, Registrable Securities.

(h) The term "Rule 144" shall mean Rule 144 promulgated under the Securities Act.

(i) The term "SEC" shall mean the Securities and Exchange Commission.

(j) The term "Selling Expenses" shall mean underwriting discounts and commission and fees of disbursements of counsel for the selling Holder or Holders.

1.2 DEMAND REGISTRATION.

(a) Subject to the conditions of this Section 1.2, if the Company shall receive a written request from either the Investor or Holders of a majority of the Registrable Securities then outstanding (in either case, the "Initiating Holders") that the Company file a registration statement under the Securities Act covering the registration of Registrable Securities then outstanding such that the anticipated aggregate offering price, net of underwriting discounts and commissions, would exceed $5,000,000 (a "Qualified Public Offering"), then the Company shall, within ten (10) days of the receipt thereof, give written notice of such request to all Holders, and subject to the limitations of this Section 1.2, use its best efforts to effect, as soon as practicable, the registration under the Securities Act of all Registrable Securities that the Holders request to be registered; provided that the Company shall file the registration statement no later than thirty (30) days following receipt of such notice. Such registration statement may be filed on any appropriate registration form for which the Company is then eligible (including Form S-3) that contemplated an offering of the type proposed by the Initiating Holders in the request made pursuant to the Section 1.2.

(b) If the Initiating Holders intend to distribute the Registrable Securities covered by their request by means of an underwriting, they shall so advise the Company as a part of their request made pursuant to this Section 1.2 or any request pursuant to Section 1.4 and the Company shall include such information in the written notice referred to in Section 1.2(a) or Section 1.4(a), as applicable. In such event, the right of any Holder to include its Registrable Securities in such registration shall be conditioned upon such Holder's participation in such

-2-

underwriting and the inclusion of such Holder's Registrable Securities in the underwriting to the extent provided herein. The Company and all Holders proposing to distribute their securities through such underwriting shall enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting by a majority in interest of the Initiating Holders (which underwriter or underwriters shall be reasonably acceptable to the Company). Notwithstanding any other provision of this Section 1.2 or Section 1.4, if the underwriter advises the Company that marketing factors require a limitation of the number of shares to be underwritten (including Registrable Securities) then the Company shall so advise all Holders of Registrable Securities which would otherwise be underwritten pursuant hereto, and the number of shares that may be included in the underwriting shall be allocated on a pro rata basis based on the total number of Registrable Securities held by all such Holders. Any Registrable Securities excluded or withdrawn from such underwriting shall be withdrawn from the registration.

(c) The Company shall not be required to effect a registration pursuant to this Section 1.2:

(i) prior to December 31, 2001;

(ii) after the Company has effected three (3) registrations pursuant to this Section 1.2, and such registrations have been declared or ordered effective;

(iii) during the period starting 30 days prior to the date of filing of, and ending on the date ninety (90) days following the effective date of the registration statement pertaining to a public offering of securities by the Company; provided that the Company makes reasonable good faith efforts to cause such registration statement to become effective; or

(iv) if the Company shall furnish to Holders requesting a registration statement pursuant to this Section 1.2, a certificate signed by the Chairman of the Board or Chief Executive Officer of the Company stating that in the good faith judgment of the Board of Directors of the Company, it would be seriously detrimental to the Company and its shareholders for such registration to be effected at such time (it being acknowledged that the Investor's decision to sell or any direct or perceived impact of that decision on any related business or commercial relationships between the Investor and the Company shall not be deemed seriously detrimental within the meaning of this provision), in which event the Company shall have the right to defer such filing for a period of not more than ninety (90) days after receipt of the request of the Initiating Holders; provided, however, that such right to delay a request shall not be exercised by the Company more than once in any twelve (12) month period.

1.3 PIGGY-BACK REGISTRATION

(a) If (but without any obligation to do so) the Company proposes to register (including for this purpose a registration effected by the Company for shareholders other than the Holders) any of its stock or other securities under the Securities Act in connection with the public offering of such securities (other than a registration relating solely to the sale of securities to participants in a Company stock plan or a registration relating to a corporate reorganization or other transaction under Rule 145 of the Securities Act), the Company shall, at such time,

-3-

promptly give each Holder written notice of such registration. Upon the written request of each Holder given within twenty (20) days after delivery of such notice by the Company in accordance with Section 3.5, the Company shall, subject to the provisions of Section 1.3(c), use all reasonable efforts to cause to be registered under the Securities Act all of the Registrable Securities that each such Holder has requested to be registered; provided, however, that the Company shall not be obligated to include any Registrable Securities in any such registration, qualification or compliance, pursuant to this Section 1.3 prior to December 31, 2001.

(b) RIGHT TO TERMINATE REGISTRATION. The Company shall have the right to terminate or withdraw any registration initiated by it under this Section 1.3 prior to the effectiveness of such registration whether or not any Holder has elected to include securities in such registration. The expenses of such withdrawn registration shall be borne by the Company in accordance with Section 1.7 hereof.

(c) UNDERWRITING REQUIREMENTS. In connection with any offering involving an underwriting of shares of the Company's capital stock, the Company shall not be required under this Section 1.3 to include any of the Holders' securities in such underwriting unless they accept the customary terms of the underwriting as reasonably agreed upon between the Company and the underwriters selected by it (or by other persons entitled to select the underwriters) and enter into an underwriting agreement in customary form with an underwriter or underwriters selected by the Company, provided that if the underwriters determine in good faith that marketing factors require a limitation on the number of shares to be underwritten, then the Company shall be required to include in the offering only that number of such securities, including Registrable Securities, that the underwriters determine in good faith will not jeopardize the success of the offering (the securities so included to be apportioned pro rata among the selling Holders and any other selling shareholders having similar rights according to the total amount of securities proposed to be included therein by each selling Holder and any other selling shareholder holding similar rights or in such other proportions as shall mutually be agreed to by such selling Holders), but in no event shall the amount of securities of the selling Holders included in the offering be reduced below twenty-five percent (25%) of the total amount of securities included in such offering. In no event will shares of any other selling shareholder be included in such registration if such inclusion would reduce the number of shares which may be included by Holders without the written consent of Holders of not less than a majority of the Registrable Securities proposed to be sold in the offering. If any Holder disapproves of the terms of any such underwriting, such Holder may elect to withdraw therefrom by written notice to the Company and the underwriter, delivered at least ten (10) business days prior to the effective date of the registration statement. Any Registrable Securities excluded or withdrawn from such underwriting shall be excluded and withdrawn from the registration. For any Holder which is a partnership or corporation, the partners, retired partners and shareholders of such Holder, or the estates and family members of any such partners and retired partners and any trusts for the benefit of any of the foregoing person shall be deemed to be a single "Holder", and any pro rata reduction with respect to such "Holder" shall be based upon the aggregate amount of shares carrying registration rights owned by all entities and individuals included in such "Holder", as defined in this sentence.

1.4 FORM S-3 REGISTRATION. In case the Company shall receive from the Holders of Registrable Securities a written request or requests that the Company effect a registration on

-4-

Form S-3 and any related qualification or compliance with respect to all or a part of the Registrable Securities owned by such Holder or Holders, the Company shall:

(a) promptly give written notice of the proposed registration, and any related qualification or compliance, to all other Holders; and

(b) effect, as soon as practicable, such registration and all such qualifications and compliances as may be so requested and as would permit or facilitate the sale and distribution of all or such portion of such Holders' Registrable Securities as are specified in such request, together with all or such portion of the Registrable Securities of any other Holders joining in such request as are specified in a written request given within fifteen (15) days after receipt of such written notice from the Company; provided, however, that the Company shall not be obligated to effect any such registration, qualification or compliance, pursuant to this Section 1.4:

(i) prior to December 31, 2001;

(ii) if Form S-3 is not available for such offering by the Holders;

(iii) if the Holders, together with the holders of any other securities of the Company entitled to inclusion in such registration, propose to sell Registrable Securities and such other securities (if any) at an aggregate price to the public of less than $5,000,000;

(iv) if the Company shall furnish to the Holders a certificate signed by the Chief Executive Officer or Chairman of the Board of the Company stating that in the good faith judgment of the Board of Directors of the Company, it would be seriously detrimental to the Company and its shareholders for such registration to be effected at such time (it being acknowledged that the Investor's decision to sell or any direct or perceived impact of that decision on any related business or commercial relationships between the Investor and the Company shall not be deemed seriously detrimental within the meaning of this provision), in which event the Company shall have the right to defer the filing of the Form S-3 registration statement for a period of not more than ninety (90) days after receipt of the request of the Holder or Holders under this Section 1.4; provided, however, that the Company shall not use this right more than once in any twelve month period; or

(v) if the Company has, within the twelve (12) month period preceding the date of such request, already effected two registrations on Form S-3 for the Holders pursuant to this Section 1.4.

(c) Subject to the foregoing, the Company shall file a registration statement covering the Registrable Securities and other securities so requested to be registered as soon as practicable after receipt of the request or requests of the Holders. Registrations effected pursuant to this Section 1.4 shall not be counted as demands for registration or registrations effected pursuant to Sections 1.2 or 1.3.

1.5 OBLIGATIONS OF THE COMPANY. Whenever required under this Section 1 to effect the registration of any Registrable Securities, the Company shall, as expeditiously as reasonably possible:

-5-

(a) prepare and file with the SEC a registration statement with respect to such Registrable Securities and use all reasonable efforts to cause such registration statement to become effective, and, upon the request of the Holders of a majority of the Registrable Securities registered thereunder, keep such registration statement effective for a period of up to one hundred twenty
(120) days or, if earlier, until the distribution contemplated in the Registration Statement has been completed;

(b) prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection with such registration statement as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement;

(c) furnish to the Holders such numbers of copies of a prospectus, including a preliminary prospectus, in conformity with the requirements of the Securities Act, and such other documents as they may reasonably request in order to facilitate the disposition of Registrable Securities owned by them;

(d) use all reasonable efforts to register and qualify the securities covered by such registration statement under such other securities or Blue Sky laws of such jurisdictions as shall be reasonably requested by the Holders, provided that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such states or jurisdictions;

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

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

(g) furnish, at the request of a majority of the Holders participating in the registration, on the date that such Registrable Securities are delivered to the underwriters for sale, if such securities are being sold through underwriters, or, if such securities are not being sold through underwriters, on the date that the registration statement with respect to such securities becomes effective, (i) an opinion, dated as of such date, of the recognized securities counsel representing the Company for the purposes of such registration, in form and substance as is customarily given to underwriters in an underwritten public offering and reasonably satisfactory to a majority in interest of the Holders requesting registration, addressed to the underwriters, if any, and to the Holders requesting registration of Registrable Securities and
(ii) a letter dated as of such date, from the independent certified public accountants of the Company, in form and customarily given by independent certified public accountants to underwriters in an underwritten public offering and reasonably satisfactory to a majority in interest of the Holders requesting registration, addressed to the underwriters, if any, and if permitted by applicable accounting standards, to the Holders requesting registration of Registrable Securities.

-6-

(h) cause all such Registrable Securities registered pursuant hereunder to be listed on each securities exchange on which similar securities issued by the Company are then listed; and

(i) provide a transfer agent and registrar for all Registrable Securities registered pursuant hereunder and a CUSIP number for all such Registrable Securities, in each case not later than the effective date of such registration.

1.6 INFORMATION FROM HOLDER. It shall be a condition precedent to the obligations of the Company to take any action pursuant to this Section 1 with respect to the Registrable Securities of any selling Holder that such Holder shall furnish to the Company such information regarding itself, the Registrable Securities held by it, and the intended method of disposition of such securities as shall be required to effect the registration of such Holder's Registrable Securities.

1.7 EXPENSES OF REGISTRATION. All expenses other than Selling Expenses incurred in connection with registrations, filings or qualifications pursuant to Sections 1.2, 1.3 and 1.4, including (without limitation) all registration, filing and qualification fees, printers' and accounting fees, fees and disbursements of counsel for the Company shall be borne by the Company. All Selling Expenses incurred in connection with any registration hereunder, shall be borne by the holders of the securities so registered pro rata on the basis of the number of shares so registered. Notwithstanding anything else in this
Section 1.7 to the contrary, in the event a Holder demands registration pursuant to Sections 1.2 or 1.4 after such time at which all Registrable Securities held by such Holder (and any affiliate of the Holder with whom such Holder must aggregate its sales under Rule 144) can in the written opinion of securities counsel for the Company provided to such Holder be sold in any three (3) month period without registration in compliance with Rule 144, all registration, filing and qualification fees, printers' and accounting fees, fees and disbursements of counsel for the Company incurred in connection with such registration, filing or qualification shall be borne by such Holder; provided that such Holder will not bear accounting fees or fees and disbursements of counsel to the Company that, in the aggregate, exceed $50,000.

1.8 INDEMNIFICATION. In the event any Registrable Securities are included in a registration statement under this Section 1:

(a) The Company will indemnify and hold harmless each Holder, the partners or officers, directors and shareholders of each Holder, legal counsel and accountants for each Holder, any underwriter (as defined in the Securities Act) for such Holder and each person, if any, who controls such Holder or underwriter within the meaning of the Securities Act or the Exchange Act, against any losses, claims, damages or liabilities (joint or several) to which they may become subject under the Securities Act, the Exchange Act or any state securities laws, insofar as such losses, claims, damages, or liabilities (or actions in respect thereof) arise out of or are based upon any of the following statements, omissions or violations (collectively a "Violation"): (i) any untrue statement or alleged untrue statement of a material fact contained in such registration statement, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, (ii) the omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein not misleading, or (iii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any state securities laws or any rule or regulation promulgated under the

-7-

Securities Act, the Exchange Act or any state securities laws; and the Company will reimburse each such Holder or controlling person as incurred for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the indemnity agreement contained in this subsection l.8(a) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld), nor shall the Company be liable in any such case for any such loss, claim, damage, liability or action to the extent that it arises out of or is based upon a Violation that occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by any such Holder, underwriter or controlling person; provided further, however, that the foregoing indemnity agreement with respect to any preliminary prospectus shall not inure to the benefit of any Holder or underwriter, or any person controlling such Holder or underwriter, from whom the person asserting any such losses, claims, damages or liabilities purchased shares in the offering, if a copy of the prospectus (as then amended or supplemented if the Company shall have furnished any amendments or supplements thereto) was not sent or given by or on behalf of such Holder or underwriter to such person, if required by law so to have been delivered, at or prior to the written confirmation of the sale of the shares to such person, and if the prospectus (as so amended or supplemented) would have cured the defect giving rise to such loss, claim, damage or liability.

(b) Each selling Holder will indemnify and hold harmless the Company, each of its directors, each of its officers who has signed the registration statement, each person, if any, who controls the Company within the meaning of the Securities Act, legal counsel and accountants for the Company, any underwriter, any other Holder selling securities in such registration statement and any controlling person of any such underwriter or other Holder, against any losses, claims, damages or liabilities (joint or several) to which any of the foregoing persons may become subject, under the Securities Act, the Exchange Act or any state securities laws, insofar as such losses, claims, damages or liabilities (or actions in respect thereto) arise out of or are based upon any Violation, in each case to the extent (and only to the extent) that such Violation occurs in reliance upon and in conformity with written information furnished by such Holder expressly for use in connection with such registration; and each such Holder will reimburse any person intended to be indemnified pursuant to this subsection l.8(b), for any legal or other expenses reasonably incurred by such person in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the indemnity agreement contained in this subsection l.8(b) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Holder (which consent shall not be unreasonably withheld), provided that in no event shall any indemnity under this subsection l.8(b) exceed the gross proceeds from the offering received by such Holder.

(c) Promptly after receipt by an indemnified party under this Section 1.8 of notice of the commencement of any action (including any governmental action), such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 1.8, deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however,

-8-

that an indemnified party (together with all other indemnified parties that may be represented without conflict by one counsel) shall have the right to retain one separate counsel, with the fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such proceeding. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action, if (but only if) prejudicial to its ability to defend such action, shall relieve such indemnifying party of any liability to the indemnified party under this Section 1.8, but the omission so to deliver written notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Section 1.8.

(d) If the indemnification provided for in this Section 1.8 is unavailable to an indemnified party or is insufficient to hold to such indemnified party harmless against any such loss with respect to any loss, liability, claim, damage or expense referred to herein, then the indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such loss, liability, claim, damage or expense in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the statements or omissions that resulted in such loss, liability, claim, damage or expense, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties' relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission; provided that in no event shall any Holder be required to contribute an amount that exceeds the proceeds received by such Holder from the Offering.

(e) Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in any underwriting agreement entered into in connection with an underwritten public offering are in conflict with the foregoing provisions, the provisions in the underwriting agreement shall control.

(f) The obligations of the Company and Holders under this Section 1.8 shall survive the completion of any offering of Registrable Securities in a registration statement under this Section 1, and the termination of this agreement. No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation.

1.9 REPORTS UNDER SECURITIES EXCHANGE ACT OF 1934. With a view to making available to the Holders the benefits of Rule 144 and any other rule or regulation of the SEC that may at any time permit a Holder to sell securities of the Company to the public without registration or pursuant to a registration on Form S-3, the Company agrees to:

-9-

(a) make and keep public information available, as those terms are understood and defined in Rule 144, at all times while the Company is a reporting issuer under the Exchange Act;

(b) file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act; and

(c) furnish to any Holder, so long as the Holder owns any Registrable Securities, forthwith upon request (i) a written statement by the Company that it has complied with the reporting requirements of Rule 144, the Securities Act and the Exchange Act (at all times it remains subject to such reporting requirements), or that it qualifies as a registrant whose securities may be resold pursuant to Form S-3, (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company, and (iii) such other information as may be reasonably requested in availing any Holder of any rule or regulation of the SEC that permits the selling of any such securities without registration or pursuant to such form.

1.10 ASSIGNMENT OF REGISTRATION RIGHTS. The rights to cause the Company to register Registrable Securities pursuant to Sections 1.2, 1.3 and 1.4 hereof may be assigned by a Holder to a transferee or assignee of such securities that is a subsidiary of the Investor or the ultimate parent of the Investor or any other subsidiary of such parent. The right to cause the Company to register Registrable Securities under Section 1.3 hereof may be assigned by the Holder to one or more unaffiliated transferees that after such assignment or transfer, hold at least that number of shares of Registrable Securities equal to one percent (1%) of the outstanding capital stock of the Company (as measured at the time of such transfer); provided: (a) the Company shall, within a reasonable time after such transfer, be furnished with written notice of the name and address of such transferee or assignee and the securities with respect to which such registration rights are being assigned; and (b) such transferee or assignee shall agree in writing to be bound by and subject to the terms and conditions of
Section 1 of this Agreement. The rights to cause the Company to register Registrable Securities pursuant to Section 1.2 may not be assigned by the Investor to an unaffiliated transferee.

2. COVENANTS OF THE COMPANY AND THE INVESTOR.

2.1 COVENANTS OF THE COMPANY

(a) Pre-emptive Right . Until such time as the Investor has sold shares in the Company such that the Investor owns not less than five percent (5%) of the outstanding capital stock of the Company, subject to the terms and conditions specified in this Section 2.1(a) the Investor shall be entitled to a pre-emptive right with respect to future sales by the Company of its Shares (as hereinafter defined). Each time the Company proposes to offer any shares of, or securities convertible into or exchangeable or exercisable for any shares of, any class of its capital stock ("Shares"), the Company shall notify the Investor in accordance with the following provisions.

(i) The Company shall deliver a notice in accordance with Section
3.5 ("Notice") to the Investor stating (1) its bona fide intention to offer such Shares, (2) the number

-10-

of such Shares to be offered, and (3) the price and terms upon which it proposes to offer such Shares.

(ii) By written notification received by the Company, within twenty (20) calendar days after receipt of the Notice, the Investor may elect to purchase or obtain, at the price and on the terms specified in the Notice, up to that portion of such Shares that equals the proportion that the number of shares of Registrable Securities issued and held by the Investor bears to the total number of shares of Common Stock of the Company then outstanding (assuming full conversion of all convertible securities).

(iii) If all Shares that the Investor is entitled to obtain pursuant to subsection 2.1(a)(ii) are not elected to be obtained as provided in subsection 2.1(a)(ii) hereof, the Company may, during the ninety (90) day period following the expiration of the period provided in subsection 2.1(a)(ii) hereof, offer the remaining unsubscribed portion of such Shares either: (1) in a private offering to any person or persons at a price not less than, and upon terms no more favorable to the offeree than those specified in the Notice, or (2) pursuant to a registered offering. If the Company does not either enter into an agreement for the issue and sale of the Shares within such period, the right provided hereunder shall be deemed to be revived and such Shares shall not be offered unless first reoffered to the Investor in accordance herewith.

(iv) The right of first offer in this paragraph 2.1(a) shall not be applicable to (1) the issuance or sale of shares of Common Stock (or options therefor) to employees, directors and consultants for the primary purpose of soliciting or retaining their services, (2) the issuance of securities pursuant to the conversion or exercise of convertible or exercisable securities, (3) the issuance of securities in connection with a bona fide business acquisition of or by the Company, whether by merger, consolidation, sale of assets, sale or exchange of stock or otherwise or (4) the issuance of stock, warrants or other securities or rights to persons or entities with which the Company has business relationships provided such issuances are for other than primarily equity financing purposes.

(v) In the event of an issue or sale of Common Stock contemplated by clause (iv) above after the close of business on June 25, 2001, the Investor shall have the right exercisable during the initial ten Business Days after the end of each fiscal quarter, commencing September 30, 2001 to purchase additional shares of Common Stock sufficient to retain its percentage ownership interest in the Company's outstanding common stock at a price per share equal to the Average Closing Price in effect on the last trading day of such fiscal quarter. For purposes of this clause (v), the "Average Closing Price" means as of any date the average of the last reported sales prices of the shares of Common Stock on the Nasdaq National Market (or other exchange in which the shares are then listed) for the ten (10) consecutive trading days ending on the date specified, or if such date is not a trading day, on the previous trading day and "Business Day" means any day other than a Saturday or Sunday or any on which commercial banks in Seattle, Washington or Helsinki, Finland are authorized or obligated by law to close.

(b) Reservation of Common Stock. The Company will at all times reserve and keep available, solely for issuance and delivery upon the exercise of the Warrant, all Common Stock issuable from time to time upon such exercise.

-11-

(c) Board Representation. Promptly following the execution and delivery of this Agreement, the Company shall take all necessary steps to appoint the Investor's designee as a member of the Company's Board of Directors, to serve until the Company's next annual shareholders' meeting at which time the Company will nominate such designee in its proxy statement to be elected by the shareholders to serve for a full term as a member of the Board of Directors. As long as the Investor has not sold shares such that the Investor holds less than five percent (5%) of the outstanding capital stock of the Company, the Company shall use its best efforts to cause and maintain the election to the Board of Directors of a representative designated by the Investor.

(d) Reimbursement of Expenses For Attending Board Meetings. The Company will reimburse the director nominated by the Investor for reasonable expenses (including airfare, lodging and other travel expenses) incurred in connection with attending meetings of the Company's Board of Directors. The director nominated by the Investor shall waive any director's fees, options or similar compensation payable by the Company to members of the Board of Directors for service as a director.

(e) Inspection Rights; Confidentiality. The Investor will have the right to receive all business information provided to the Company's Board of Directors in connection with each meeting of the Board of Directors promptly following the meeting at which such information is furnished to the Board of Directors. The Investor shall have the right to discuss the affairs, finances and accounts of the Company or any of its subsidiaries with the Company's executive officers, and to review such information as is reasonably requested all at such reasonable times and as often as may be reasonably requested, but not more than once each calendar quarter; provided, however, that the Company shall not be obligated under this Section 2.1(e) to furnish information to the extent that the Board of Directors determines in good faith that furnishing such information would be a violation of the Board's fiduciary duties

2.2 COVENANTS OF THE INVESTOR.

(a) Business Combination. The Investor covenants to and agrees with the Company that, for a period of two years from the date of this Agreement, the Investor will not act in concert with another party to effect a business combination involving, or sale of material assets of, the Company (including any soliciting of proxies designed to achieve such a transaction), except in the event of a third party Change-in-Control Transaction.

(b) Accumulation of Shares. The Investor covenants to and agrees with the Company that, for a period of two years from the date of this Agreement, the Investor shall not, without the prior written consent of the Company, increase its ownership interest in the Company, directly or indirectly, other than as a result of: (i) the Investor exercising the Warrant in whole in part, (ii) stock splits, dividends, rights offerings and recapitalizations;
(iii) any decrease in the total number of outstanding shares of the Company; and
(iv) a Change-in-Control Transaction; provided, however, the Investor may acquire additional shares of the Company's capital stock in the event any third party or group acquires an ownership interest in the Company that would exceed the Investor's, provided that the Investor shall only be allowed to acquire that number of shares necessary to have an equal ownership interest as such third party or group.

-12-

(c) Exception. Nothing in Section 2.2(a) or 2.2(b) or elsewhere in this Agreement, shall be deemed in any way to prohibit or limit: (i) any lawful action taken by the Investor in direct competition with any bona fide offer by a third party seeking a Change-in-Control Transaction with the Company,
(ii) any lawful action of any director nominated by the Investor and serving as a member of the Company's Board of Directors acting in such capacity; and (iii) any lawful action by the Investor or any of its affiliates, officers, directors or employees in connection with ongoing or prospective business relationships with or affecting the business relationships with or affecting the Company or any of its affiliates.

(d) Private Sale of Shares to Third Party. The Investor shall not, without the prior written consent of the Company's Board of Directors, transfer any Registrable Securities in a private sale to a third-party investor or "group" (as defined for purposes of Section 13(d) of the Exchange Act) if, as a result of such transfer, any individual or "group" would acquire more than two percent (2%) of the outstanding capital stock of the Company.

(e) Sale of Shares to the Public. In the event the Investor sells shares of the Company's Common Stock in the public market other than pursuant to Sections 1.2, 1.3 or 1.4 hereof, the Investor shall limit those sales to either
(i) sales in "brokers' transactions" within the meaning of Rule 144; or (ii) the sale of shares to a third-party investor or "group", provided that any individual investor or "group" would not acquire more than two percent (2%) of the outstanding capital stock of the Company.

(f) Change-in-Control Transactions. In the event the Warrant is accelerated in connection with a Change-in-Control Transaction, and the Investor exercises the Warrant upon such accelerated vesting, any shares acquired by the Investor upon such exercise shall be voted, at any shareholder vote on such Change-in-Control Transaction, in proportion to the other outstanding shares entitled to vote, such that those shares held by the Investor shall not impact the outcome of such shareholder vote. Notwithstanding the above, shares held by the Investors other than as a result of the exercise of an accelerated Warrant, may be voted at the sole discretion of the Investor.

(g) Confidentiality. The Investor acknowledges that the Company may pursuant to Section 2.1(e), above, provide it with information that is confidential or proprietary to the Company and agrees that all such information designated as confidential will be held and treated by it in confidence and it will not disclose such information in any manner whatsoever, in whole or in part, to any person (other than an agent, attorney or employee of the Investor) without the Company's prior written consent. The Investor agrees that any confidential information may be used by the Investor and its agents, attorneys and employees only in connection with the Investor's investment in the Company and any commercial arrangements between them. None of the following will constitute confidential information for purposes of this agreement: (i) information already in the Investor's possession and not received in confidence from the Company; (ii) information that now or in the future is made available to the Investor by a third party which, to the Investor's knowledge, has no obligation of confidentiality to the Company with respect to such information;
(iii) information which is or becomes publicly available through no fault of the Investor or (iv) information that is independently developed by Nokia without reference to, or use of, any confidential information.

A copy of the Master Lease is attached to this Consent as Exhibit "A." Except as otherwise defined herein, all capitalized terms used herein shall have the meanings assigned in the Master Lease.

Landlord hereby gives its consent to the subleasing from Tenant to Subtenant, pursuant to that certain Sublease Agreement dated March 30, 2001 a copy of which is attached hereto as Exhibit "B" and incorporated by this reference (the "Sublease") of the entire Building Three, comprising 110,111 rentable square feet (the "Subleased Premises") which is part of the Premises described in the Master Lease, subject to the following conditions:

1. Tenant shall remain liable for the performance of all of the obligations arising under the Master Lease, as the same may be amended or modified from time to time, until the termination thereof. Except as specifically provided herein, as between Landlord and the Tenant, insofar as the specific terms, provisions or conditions of the Sublease purport to amend or modify or are in conflict with the specific terms, conditions or provisions of the Master Lease, the terms, conditions or provisions of the Master Lease shall govern and control.

2. Landlord agrees that in the event (a) the Master Lease is terminated for any reason whatsoever, (b) a rejection or disaffirmance of the Master Lease by Tenant pursuant to bankruptcy or any law affecting creditor's rights due to Tenant's default or (c) Subtenant exercises its Lease Option as more particularly set forth in Paragraph 10 below, then, provided that (i) Subtenant is not then in material default in any payments due under the Sublease and has not been in material default in any payments due under the Sublease more than twice in any twelve (12) month period, (ii) there is no existing non-rent default relating to the Sublease Premises and Subtenant has not been in material default with respect to any non-rent obligations under the Master Lease or Sublease more than twice in any twelve (12) month period, and (iii) Subtenant posts a security deposit

1

commensurate with the lease and restoration obligations under the Direct Lease, which deposit must be such, given Subtenant's then creditworthiness, as to meet a reasonable lender's criteria for a lease that makes the Building financeable on market terms for similar buildings, and (iv) the entry into a Direct Lease is approved by Landlord's lender, then Landlord shall enter into a Direct Lease with Tenant for the Sublease Premises. As used herein, "Direct Lease" means a lease on the same terms and conditions as the Master Lease, subject, however, to the security deposit requirement set forth above and to such modifications in Landlord's standard form lease as may have been required in the interim by Landlord's lender, and provided that Subtenant's ("Tenant" under the Direct Lease) obligations with respect to restoration of the Premises on surrender shall reference the condition of the Premises on commencement of the Sublease (as opposed to the condition on commencement of the Direct Lease). If Landlord and Subtenant cannot agree upon the amount of the security deposit to be provided by Subtenant for any Direct Lease pursuant to this Paragraph 2, then the amount of the security deposit shall be determined by the arbitration process stated in Paragraph 10 below. In addition, Landlord agrees to use commercially reasonable efforts to obtain within nine (9) months of the Effective Date hereof, Landlord's lender's approval of the Direct Lease rights granted to Subtenant pursuant to the terms of this Consent.

3. The consent hereby given by Landlord does not constitute a waiver of the necessity of the consent by Landlord to any subsequent subleasing, in whole or in part, of the Premises or to any assignment of the Master Lease; nor except as specifically provided herein, shall this consent be deemed to modify in any way the terms and conditions of the Master Lease nor shall it constitute agreement by Landlord with or acceptance by Landlord of any terms or provisions of any Sublease executed between Tenant and Subtenant.

4. No representation respecting the condition of the Premises or Subleased Premises has been made by the Landlord to the Subtenant.

5. Although Landlord has received a copy of the proposed Sublease between Tenant and Subtenant, it is not a party to that agreement and does not by executing this Consent agree to be bound by the terms thereof, such Sublease being an agreement between Tenant and Subtenant only.

6. Except as otherwise provided herein or in any Direct Lease: (a) Landlord shall have no obligation to accept, consider, or respond to any request, inquiry, demand or other communication from Subtenant, whether of a type described in the Sublease, or otherwise; (b) Subtenant shall have no right to enforce any of the Tenant's rights under the Master Lease against the Landlord, all of such rights being personal to the Tenant; and (c) notwithstanding Subtenant's undertaking to perform the duties, responsibilities and obligations of Tenant, as required by Paragraph 9 of this Consent, Landlord shall have no direct duties, responsibilities or obligations to Subtenant, and Subtenant shall have no rights against Landlord, Subtenant's rights being exclusively against Tenant.

2

7. If Landlord issues any notices of default under Paragraph 20 of the Master Lease, or notices relating to damage and destruction or condemnation pursuant to Paragraphs 17 and 18 of the Master Lease Landlord shall simultaneously deliver a copy of such notice to Subtenant at the address set forth below (using the notice procedures set forth in the Master Lease). Except as set forth above and except for notices to be sent pursuant to Paragraphs 17 and 18 of the Master Lease, notwithstanding anything to the contrary contained in the Sublease, Landlord shall have no obligation to deliver any notices called for under the Sublease or the Master Lease to the Subtenant. Landlord shall continue to deliver notices to the Tenant at the Premises in accordance with the Master Lease. Landlord agrees not to accept any elections by Tenant pursuant to Paragraphs 17 or 18 of the Lease relating to the Sublease Premises unless Landlord has so delivered a copy of the notice required under Paragraphs 17 or 18 as applicable, and Landlord shall use reasonable means to confirm that Subtenant is in accord with Tenant's election (but shall not be liable for failure to make such confirmation so long as Landlord has delivered notices as required hereunder).

8. As stated in Section 19, Assignment of Sublease, of the Master Lease, one-half (1/2) of any rent received by Tenant from its subtenants or assignees in excess of the Rent payable by Tenant to Landlord under this Lease (less the cost and expenses incurred by Tenant in connection with any such sublease or assignment) shall be paid to Landlord by Tenant.

9. With respect to all non-rent obligations under the Lease, Subtenant agrees to perform and fulfill all the terms, convenants, conditions, duties, responsibilities and obligations and to accept all liabilities of Tenant under the Lease relating to the Sublease Premises as if Subtenant were the Tenant under the Lease (including but not limited to indemnifications of Landlord, rights of Landlord to be named as an additional insured, and releases of Landlord, all as contained in the Lease), all to the extent same arise after the date hereof.

10. As used in this Paragraph 10, the "Renewal Exercise Period" shall mean the period not more than twenty-four (24) and not less than eighteen (18) months prior to expiration of the initial term of the Master Lease or the expiration of the first Extension Option, as the case may be. Subject to Subtenant meeting the requirements for a Direct Lease set forth in Paragraph 2 above at the time of each exercise of a renewal option, Landlord hereby grants Subtenant an option to lease the Subleased Premises on a direct basis from Landlord (the "Lease Option") for two (2) consecutive five (5) year periods at the expiration of the initial term of the Master Lease and the First Extension Option, as applicable. Subtenant shall exercise each respective Lease Option by delivering written notice to Landlord of its election during the respective Renewal Exercise Period, in which event Landlord and Subtenant, as tenant, shall enter into a Direct Lease for the Sublease Premises for the applicable Extension Option, all on the terms and conditions set forth in Section 29 of the Master Lease. In addition, Subtenant shall post a Security Deposit for

3

its obligations under the Direct Lease in an amount that would be reasonably required by landlords under leases of similar size with tenants of similar credit standing and restoration obligations. If Landlord and Subtenant cannot agree upon the amount of the Security Deposit, then the amount of the Security Deposit shall be determined using the arbitration procedure provided in Section 29 of the Master Lease concurrently with the determination of the Fair Market Rental Rate. Regardless of whether Subtenant elects to enter into a Direct Lease as provided in this Paragraph 10, the Master Lease between Landlord and Tenant shall expire at the end of the initial term of the Master Lease as by expiration of its term notwithstanding any Direct Lease between Landlord and Subtenant, and Tenant shall be entitled to a return of the then-existing balance of its security deposit in accordance with the terms and conditions of the Master Lease (provided further that if Landlord and Subtenant have entered into a Direct Lease with security satisfactory to Landlord securing restoration obligations, then Tenant's restoration obligations shall be superseded by the obligations of Subtenant under the Direct Lease).

11. Landlord hereby consents, pursuant to Section 7 of the Master Lease, to use of the Sublease Premises for laboratory uses of the types generally permitted by institutional landlords of similar buildings in multi-tenant developments in the Seattle area, provided that Landlord shall be permitted to impose such special restrictions or precautions as are commonly required by institutional landlords of similar tenants in the area. Landlord agrees to diligently process, pursuant to the consent provisions of the Master Lease, additional requests for additional permitted uses.

12. Notwithstanding anything in the Master Lease to the contrary, Landlord hereby agrees the Subtenant shall be permitted to exercise Tenant's right to install signage on the Sublease Premises pursuant to Section 37 of the Master Lease.

13. Landlord, Tenant and Subtenant contemplate that Subtenant will request of Tenant (and Tenant will in response request of Landlord) consent to alterations that will convert portions of the Premises to laboratory or other related non-office space, and that such alterations may be ones that Landlord will require Tenant to restore on termination of the Master Lease or Direct Lease, if applicable, pursuant to the terms of the Master Lease and this Consent. The installation by Subtenant of any improvements or alterations to the Subleased Premises necessary for the Permitted Use shall require Landlord's consent pursuant to Section 14 of the Master Lease. Landlord acknowledges that, pursuant to the Master Lease: "at the time Tenant submits plans for alterations to Landlord for Landlord's approval, Tenant may request that Landlord elect whether such alterations shall be removed at the termination of this Lease, and if so requested, Landlord shall make such election simultaneous with its approval of the alterations." Subtenant agrees to provide to Landlord concurrently with its submission of plans for Landlord's consent, a removal and restoration plan prepared by Subtenant's approved contractor (the "Removal Plan") which Removal Plan shall provide an estimate of the cost to remove such alterations and restore the Premises to its pre-alteration condition

4

following the termination of the sublease or Direct Lease, as applicable. The parties further acknowledge that Landlord may (and is expected to) require Tenant to post or arrange for the posting of a letter of credit securing restoration obligations under the Master Lease if the Sublease Premises are materially altered from their current improved state and Landlord requires that Subtenant remove any proposed alterations to be installed by Subtenant pursuant to the terms of the Master Lease and this Consent. This restoration obligation will be triggered by expiration or earlier termination of the Master Lease unless Landlord and Subtenant have entered into a Direct Lease (which Direct Lease shall, in such event, include a security deposit pursuant to Paragraph 2 above in the form of a letter of credit to secure restoration obligations). Tenant may (and is expected to) satisfy letter of credit requirements relating to restoration obligations by causing Subtenant to post a satisfactory letter of credit payable directly to Landlord, and Subtenant hereby recognizes this obligation. The form of the Letter of Credit and Landlord's rights thereunder are as set forth in Exhibit C, which is hereby incorporated by reference. Exhibit C is drafted on the assumption that the Letter of Credit will be posted directly by Subtenant. If posted by Tenant, the references shall be amended to reflect that fact. The amount of the restoration letter of credit to be posted pursuant to this Section 13 shall be equal to one hundred fifteen percent (115%) of the amount estimated in the Removal Plan for the cost of removal and Premises restoration relating to such alterations as Subtenant has elected to install and Landlord is requiring be removed pursuant to the Master Lease and this Consent, provided, however, that Tenant's contractor's estimate of the cost of removal and restoration shall be in lease-expiration dollars (calculated on an assumed 3% per annum inflation in costs).

14. Landlord agrees that within sixty (60) days of the parties' entry into a Direct Lease pursuant to the terms set forth herein, Landlord shall use commercially reasonable efforts to obtain for Subtenant's benefit (as tenant under such Direct Lease) a commercially reasonable form of non-disturbance agreement from any mortgage or ground lessor of the Subleased Premises.

15. Landlord and Tenant hereby represent and warrant to Subtenant and each other that (a) attached hereto as Exhibit "A" is a true correct and complete copy of the Master Lease and all amendments or side letter agreements related thereto (b) the Master Lease is in full force and effect, and has not been amended (c) that all Base Monthly Rent, monthly estimates of Tenant's Share of Expenses and other sums due under the Master Lease have been paid through April 30, 2001, (d) the Master Lease commenced on July 25, 2000, and shall expire on July 31, 2012; and (e) that neither Landlord nor Tenant is aware of any material defaults under the Master Lease by themselves or by the other party. Landlord and Tenant agree not to enter into any amendments affecting the Sublease Premises during the term of the Master Lease without Subtenant's prior written approval, which shall not be unreasonably withheld, conditioned, or delayed.

EXHIBIT A
MASTER LEASE

10

EXHIBIT B
SUBLEASE AGREEMENT

11

EXHIBIT C
LETTER OF CREDIT RIGHTS AND CRITERIA

A. AMOUNT OF LETTER OF CREDIT. Landlord and Subtenant acknowledge and agree that in accordance with Section 13 of the Landlord's Consent, (i) Subtenant shall cause a Letter of Credit in the amount determined pursuant to
Section 13 of the Landlord's Consent, to be issued by the L/C Bank in favor of Landlord, and its successors, assigns and transferees; (ii) Subtenant will cause the Letter of Credit to remain in full force and effect during the entire Term of the Sublease and any Direct Lease and thereafter until the earlier of the date Landlord acknowledges Subtenant has completed all restoration obligations under the lease or 60 days after expiration or earlier termination of the Lease; and (iii) the initial Letter of Credit will be delivered to Landlord prior to Subtenant commencing any alterations on the Premises that will be required to be removed pursuant to Section 13 (and will be adjusted in amount if additional alterations are thereafter constructed that must be removed). The specific requirements for the Letter of Credit and the rights of Landlord to make draws thereon will be as set forth in Section 13 of the Landlord's Consent and this Exhibit C.

B. PAYMENT AND HOLDING OF DRAW PROCEEDS. Immediately upon, and at any time or from time to time after, the occurrence of any one or more Draw Events, Landlord will have the unconditional right to draw on the Letter of Credit, in the full amount thereof or in any lesser amount or amounts as Landlord may determine, in its sole and absolute discretion, in accordance with Section 13 of the Landlord's Consent and this Exhibit C. Upon the payment of Landlord of the Draw Proceeds, Landlord will hold the Draw Proceeds in its own name and for its own account, without liability for interest, and as security for the performance by Subtenant of Subtenant's covenants and obligations (theretofore or thereafter arising) under Section 13 of the Landlord's Consent and this Exhibit C, and will be entitled to use and apply any and all of the Draw Proceeds from time to time solely to compensate Landlord hereunder. Among other things, it is expressly understood that the Draw Proceeds will not be considered an advance payment of Base Rent or Additional Rent or a measure of Landlord's damages resulting from any event of default under the Master Lease or this Sublease (past, present or future). Further, immediately upon the occurrence of any one or more Draw Events, Landlord may, from time to time and without prejudice to any other remedy, use the Draw Proceeds (whether from a contemporaneous or prior draw on the Letter of Credit) to the extent necessary to pay to Landlord any and all amounts to which Landlord is entitled in connection with the pursuit of any one or more of its remedies hereunder, and to compensate Landlord for any and all other damage, injury, expense or liability caused to Landlord by any and all such Events of Default. Any delays in Landlord's draw on the Letter of credit or in landlord's use of the Draw Proceeds as provided in Section 13 of the Landlord's Consent and this Exhibit C will not constitute a waiver by Landlord of any of its rights hereunder with respect to the Letter of Credit or the Draw Proceeds. Following any such application of the Draw Proceeds, Subtenant will either pay to Landlord on demand the cash amount so applied in order to restore the Draw Proceeds to the full amount thereof immediately prior to such application or cause the Letter of Credit to be replenished to its full amount thereunder. Landlord will not be liable for any indirect, consequential, special or punitive damages incurred by Subtenant arising from a claim that Landlord violated the bankruptcy code's automatic stay in connection with any draw by Landlord of any Draw Proceeds, Landlord's liability under such circumstances being limited to the reimbursement of direct costs as and to the extent expressly provided in Section 13 of the Landlord's Consent and this Exhibit C. Nothing in this Landlord's Consent or in the Letter of Credit will confer upon Subtenant any property rights or interests in any Draw Proceeds; provided, however, that upon the expiration or earlier termination of the Lease, and so long as there then exist no Draw Events hereunder, Landlord agrees to return any remaining unapplied balance of the Draw Proceeds then held by Landlord, and the Letter of Credit itself (if and to the extent not previously drawn in full) to the L/C Bank.

12

C. TRANSFERABILITY. If Landlord transfers its interest in the Premises, or any portion thereof, during the Term, Landlord may transfer the Letter of Credit and any and all Draw Proceeds then held by Landlord to the transferee and thereafter will have no further liability with respect to the Letter of Credit or the Draw Proceeds, including, without limitation, any liability for the return of the Letter of Credit. Subtenant is responsible for any and all fees or costs (whether payable to the L/C Bank or otherwise) in order to effect such transfer of the Letter of Credit.

D. APPLICABLE DEFINITIONS.

"DRAW EVENT" means each of the following events:

(a) the occurrence of any one or more of the following: (i) Subtenant's filing of a petition under any chapter of the Bankruptcy Code, or under any federal, state or foreign bankruptcy or insolvency statute now existing or hereafter enacted, or Subtenant's making a general assignment or general arrangement for the benefit of creditors, (ii) the filing of an involuntary petition under any chapter of the Bankruptcy Code, or under any federal, state or foreign bankruptcy or insolvency statute now existing or hereafter enacted, or the filing of a petition for adjudication of bankruptcy or for reorganization or rearrangement, by or against Subtenant (or its guarantor hereunder) and such filing not being dismissed within 60 days, (iii) the entry of an order for relief under any chapter of the Bankruptcy Code, or under any federal, state or foreign bankruptcy or insolvency statute now existing or hereafter enacted, (iv) the appointment of a "custodian," as such term is defined in the Bankruptcy Code (or of an equivalent thereto under any federal, state or foreign bankruptcy or insolvency statute now existing or hereafter enacted), for Subtenant, or the appointment of a trustee or receiver to take possession of substantially all of Subtenant's assets located at the Premises or of Subtenant's interest in the Sublease and possession not being restored to Subtenant within 60 days, or (v) the subjection of all or substantially all of Subtenant's assets located at the Premises or of Subtenant's interest in the Sublease to attachment, execution or other judicial seizure and such subjection not being discharged within 60 days; or

(b) the failure of Subtenant, not less than 30 days prior to the stated expiration date of the Letter of Credit then in effect, to cause an extension, renewal or replacement issuance of the Letter of Credit, at the reduced amount, if any, applicable under Section 13 of the Landlord Consent, to be effected, which extension, renewal or replacement issuance will be made by the L/C Bank, and will otherwise meet all of the requirements of the initial Letter of Credit hereunder, which failure will be a Draw Event under Section 13 of the Landlord's Consent and this Exhibit C; or

(c) The failure of Subtenant to fulfill those restoration obligations under Section 26 of the Master Lease which are applicable to the Subleased Premises and Section 13 of the Landlord's Consent to which this is attached.

This Sublease Agreement ("Sublease") dated for reference purposes March 30, 2001, and is made between F5 Networks, Inc., a Washington corporation ("Sublandlord"), and Cell Therapeutics, Inc., a Washington corporation ("Subtenant"). This Sublease shall be effective on the date (the "Effective Date") that it is signed by Sublandlord and Subtenant, and Master Landlord has consented to this Sublease as provided in Section 14 below.

RECITALS

A. Pursuant to the Amended and Restated Office Lease Agreement dated April 3, 2000, between 401 Elliott West L.L.C., a Washington limited liability corporation, as landlord ("Master Landlord"), and Sublandlord as tenant (together with all modifications, amendments, riders and exhibits thereto, the "Master Lease"), a copy of which is attached hereto as Exhibit A, Master Landlord leased to Sublandlord 110,111 rentable square feet of space in Building Three (as defined in the Master Lease) located at 501 Elliott Avenue West in Seattle, Washington (the "Building"), which comprises all of the rentable area in the Building.

B. Sublandlord wishes to sublease the entire Building to Subtenant, with the sublease term for different portions of the Subleased Premises to start on different dates, on the terms and conditions provided below.

C. Unless otherwise provided herein, all capitalized terms shall have the meaning set forth in the Master Lease.

NOW, THEREFORE, in consideration of the above Recitals which are incorporated by this reference, the mutual covenants contained in this Sublease, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged by the parties, Sublandlord and Subtenant hereby agree as follows:

AGREEMENT

1. SUBLEASE

Sublandlord hereby subleases to Subtenant and Subtenant hereby subleases from Sublandlord the entire Building (the "Subleased Premises"), for the Term (as defined in Section 2 below), at the rental, and upon all of the terms and conditions set forth, together with the right to use, in common with others entitled thereto, the Common Areas (as defined in the Master Lease). The Subleased Premises are comprised of the following areas on different floors in the Building (each, an "Area"): 19,333 rentable square feet on the first floor described as "Area 1A;" 4,442 rentable square feet on the first floor of the Building described as "Area 1B;" 14,666 rentable square feet on the second floor described as "Area 2A;" 14,188 rentable square feet on the second floor described as "Area 2B;" 28,741 rentable square feet on the third floor described as "Area 3;" and 28,741 rentable square feet on the fourth floor described as "Area 4." Sublandlord shall deliver to Subtenant possession of the Subleased Premises in their "AS IS"


condition. The Subleased Premises are more particularly shown on Exhibit "C" attached hereto and incorporated by this reference.

2. TERM

The term of this Sublease (the "Term") shall commence on the following dates (each, a "Commencement Date") for each Area: (i) the Effective Date for Areas 1B, 2B, 3 and 4; (ii) February 1, 2002 for Area 1A; and (iii) for Area 2A, the date Sublandlord has for any reason recovered possession of that Area from NeoRx Corporation, Inc., a Washington corporation ("NeoRx"). Sublandlord shall deliver notice of termination to NeoRx within five (5) business days after Sublandlord receives written notice from Subtenant stating that Subtenant wishes for Sublandlord to terminate NeoRx's tenancy. Subtenant acknowledges that Sublandlord must give NeoRx written notice nine (9) months prior to the effective termination date, and that Sublandlord may not require that the termination date be sooner than November 1, 2002. Sublandlord shall use commercially reasonable efforts to regain possession of Area 2A in a timely manner after delivering a notice of termination to NeoRx. Notwithstanding the foregoing, Subtenant's obligation to pay Base Rent and Additional Rent for Areas 1B, 2B, 3 and 4 shall be calculated from April 6, 2001 (which shall be the "Rent Commencement Date" for those Areas). The Rent Commencement Dates for Areas 1A and 2A shall be the same as the Commencement Dates for those Areas.

Sublandlord and Subtenant hereby acknowledge and agree that Area 3 is currently subleased by Subtenant from Sublandlord pursuant to that certain Sublease dated December 4, 2000 (the "Prior Sublease"). Sublandlord and Subtenant agree that on the Effective Date hereto the Prior Sublease shall terminate and the parties shall have no further rights or obligations thereunder. The Term for the entire Subleased Premises shall expire on July 31, 2012 (the "Expiration Date").

If for any reason Sublandlord does not deliver to Subtenant possession of Areas 1A or 2A on the Commencement Date for those Areas, then Base Rent and Operating Expenses, as defined in Section 3, for those Areas shall abate on a per diem basis until delivery of possession as required herein. In the event Sublandlord does not deliver possession of any Area within sixty (60) days of the respective Commencement Date for that Area, then Subtenant shall have the right to terminate this Sublease with respect to the subject Area by providing written notice of such election to terminate to Sublandlord or Subtenant may specifically enforce Sublandlord's obligations to deliver possession of that Area. The Expiration Date shall not be extended due to any delay in the Commencement Dates for any of the Areas.

Upon the execution of this Sublease by Sublandlord and Subtenant, Subtenant shall have the right to enter the Sublease Premises to begin planning and design work for the alterations contemplated by Section 10 below. Subtenant shall indemnify, defend and hold Sublandlord harmless from any liability or damages that arises from such early entry. This indemnification and defense obligation shall survive termination of this Sublease.

3. BASE RENT AND OPERATING EXPENSES

3.1 BASE RENT

Subtenant shall pay to Sublandlord monthly installments of Base Rent (as that term is defined below) on or before the first day of each calendar month during the Term at Sublandlord's address stated in Section 14. The monthly installments of Base Rent shall be prorated on a per diem basis for the first or last month of the Term if the Rent Commencement Date for any Area or the Expiration Date is not the first day or last day of a calendar month. Subtenant shall pay to Sublandlord within one (1) business day after the Effective Date.

a) Area 1A and 1B. The annualized Base Rent for Area 1A and Area 1B on the first floor of the Building shall be $26.50 per rentable square foot for the period from the Commencement Date for each Area through December 31, 2003. On January 1, 2004, the annualized Base Rent for Areas 1A and 1B shall be $27.50 per rentable square foot, and the annualized Base Rent for those Areas shall increase on January 1 of each subsequent year during the Term by $1.00 per rentable square foot.

b) Area 2A, 2B, 3 and 4. The annualized Base Rent for Areas 2A, 2B, 3 and 4, on the second, third and fourth floors respectively, of the Building shall be $28.00 per rentable square foot for the period from the Commencement Date for each Area through December 31, 2003. On January 1, 2004, the annualized Base Rent for Areas 2A, 2B, 3 and 4 shall be $29.00 per rentable square foot, and shall increase on January 1 of each subsequent year during the Term at the rate of $1.00 per rentable square foot.

3.2 OPERATING EXPENSES

Subtenant shall pay to Sublandlord as Additional Rent its proportionate share of all Expenses, as defined in Section 4(c) of the Master Lease, including all increases in Expenses during the Term of this Sublease. Subtenant's proportionate share of Expenses will be calculated from the Rent Commencement Dates for each Area, and the first monthly installment shall be due within one (1) business day after the Effective Date. Subtenant's proportionate share of Expenses separately allocated to the Building shall be calculated by dividing the agreed area of the portion of the Subleased Premises possession of which has been delivered to Subtenant pursuant to Paragraph 2 above by the total area of the Building, which is deemed to be 110,111 rentable square feet. Subtenant's proportionate share will change during the Term as the agreed area of the Subleased Premises increases. For example, prior to the Effective Date, the Subleased Premises will include only Area 3 comprising 28,741 rentable square feet, which results in Subtenant's proportionate share of 26.10%. On the Effective Date, the Subleased Premises will likely include Areas 1B, 2B, 3, and 4 comprising 76,112 rentable square feet, which results in Subtenant's proportionate share of 69.12%. On February 1, 2002, Area 1A will be included in the Subleased Premises, which will increase the agreed area of the Subleased Premises to 95,445 rentable square feet, resulting in Subtenant's proportionate share of 86.68%. Finally, upon the addition of Area 2A, Subtenant's proportionate share will be 100%.

3

Sublandlord shall continue to pay all Expenses separately allocated to portions of the Premises (as defined in the Master Lease) possession of which has not been delivered to Subtenant pursuant to Paragraph 2 above. If any Expenses that are attributable to the occupancy of the remainder of the Premises leased by Sublandlord under the Master Lease and Building 3 and are not separately stated, then Subtenant's proportionate share shall be calculated by dividing the agreed area of the portion of the Subleased Premises possession of which has been delivered to Subtenant pursuant to Paragraph 2 above, by the combined areas of the remainder of the Premises leased by Sublandlord under the Master Lease. The area of Building 2 shall be deemed to be 85,446 rentable square feet as provided in the Master Lease. Subtenant's proportionate share of Expenses attributable to the entire Project (as defined in the Master Lease), shall be calculated by dividing the portion of the Subleased Premises possession of which has been delivered to Subtenant pursuant to Paragraph 2 above, by the Project Area, which is deemed to be 299,643 rentable square feet, as provided in the Master Lease.

4. SIGNAGE

Subtenant shall be permitted to exercise and utilize all signage rights granted to Sublandlord pursuant to Section 37 of the Master Lease with respect to the Subleased Premises, subject to all the same approvals, conditions, rules, regulations, and restrictions as set forth in the Master Lease. Sublandlord will not unreasonably withhold its consent to any signage requested by Subtenant and shall use reasonable efforts and diligence in submitting Subtenant's requests for signage to Master Landlord for approval.

5. DIRECT LEASE WITH MASTER LANDLORD UPON THE EXPIRATION OF THE TERM

Subtenant acknowledges that Sublandlord has the option to extend the term of the Master Lease for two additional terms of five (5) years each (the "Renewal Options"), the Renewal Options are not assignable, and Sublandlord is currently not willing to extend the term of the Master Lease. Sublandlord hereby relinquishes its right to exercise the Renewal Options, and agrees that Subtenant may enter into a direct lease with Master Landlord at the end of the Term. Provided, however, the foregoing relinquishment shall be deemed void and Sublandlord shall again have the right to exercise the Renewal Options without the need for any further action by either party upon the termination of this Sublease (other than by expiration on the Expiration Date) for any reason other than a material default by Sublandlord which is not cured within any applicable cure period. Sublandlord agrees that in the event Subtenant exercises its option to enter into a direct lease with Master Landlord for the Subleased Premises as more particularly provided in the Master Landlord Consent: (i) Sublandlord shall not be permitted to exercise the Renewal Options, and (ii) the Master Lease with respect to the Subleased Premises shall terminate on the expiration of the initial Lease Term under the Master Lease.

6. PARKING

Subtenant shall be permitted to exercise all parking rights to Sublandlord with respect to the Subleased Premises pursuant to Section 11 and 41 of the Master Lease with regard to those Areas of the Subleased Premises for which the Term has commenced, which is 1.9 stalls per 1,000 rentable square feet, throughout the Term of the Sublease on an unreserved basis in the

4

Building parking garage. Subtenant's parking rights shall increase as the Term commences for additional Areas. Subtenant shall pay to Sublandlord rent for the stalls in the same manner and in the same amount as charged to Sublandlord under the Master Lease. If the Master Lease provides for direct payment of parking rent to a parking garage operator, then Subtenant shall pay rent for those stalls directly to that operator.

7. SECURITY DEPOSIT

Within one (1) business day after the Effective Date, Subtenant shall deposit with Sublandlord an irrevocable, unconditional standby letter of credit issued by a financial institution reasonably acceptable to Sublandlord, in substantially the form attached to this Sublease (the "Letter of Credit") in an amount equal to Two Million Dollars ($2,000,000) as security for Subtenant's faithful performance of Subtenant's obligations hereunder ("Security Deposit"). If Subtenant fails to pay rent or other charges when due under this Sublease beyond any applicable notice and cure period, or fails to perform any of its obligations hereunder beyond any applicable notice and cure period, Sublandlord may use or apply all or any portion of the Security Deposit for the payment of any rent or other amount then due hereunder and unpaid, for the payment of any other sum for which Sublandlord may become obligated pursuant to this Sublease by reason of Subtenant's default or breach, or for any loss or damage sustained by Sublandlord as a result of Subtenant's default or breach pursuant to this Sublease. Upon demand following application of the Security Deposit pursuant to this Section 7, Subtenant shall immediately restore the Security Deposit to its full amount. Concurrently with Subtenant's delivery of the Letter of Credit, Sublandlord shall return to Subtenant the security deposit that it holds under Prior Sublease in the amount of $131,729.58. Any portion of the Security Deposit not applied pursuant to this Section 7 and remaining at the expiration of this Sublease shall be returned to Subtenant within twenty (20) days of the expiration of the Term.

8. USE OF SUBLEASED PREMISES

Sublandlord and Subtenant agree and acknowledge that Subtenant will use the Subleased Premises for laboratory purposes and that such laboratory uses are not currently permitted under the Master Lease. Sublandlord and Subtenant agree that it shall be a condition to the effectiveness of this Sublease pursuant to
Section 13 below that Master Landlord agree in the Master Landlord Consent that Laboratory use be included as a permitted use under the Master Lease. For purposes of this Sublease and the Master Lease, "Laboratory Use" shall be deemed to include the installation, operation, and maintenance of the following:

H-2 Room

H-2 is a Uniform Fire Code (UFC) classification for a particular room or building that allows the dispensing and storage of flammable and other hazardous materials. The design and construction requirements for an H-2 room are described in the Uniform Building Code (UBC) and the UFC. H-2 rooms often have requirements such as dikes or berms to trap firewater and contain spills, increased ventilation requirements, and explosion proof lighting and electrical systems;

5

Hydrogenation Facility

Use of hydrogen gas in synthetic organic chemistry is common in the biotech and pharmaceutical industries. Hydrogen gas (H2) is a flammable gas and can reach explosive mixtures in air, thus use of H2 is heavily regulated by the UFC and industry. The hydrogenation facility would likely include explosion proof lighting and electrical systems, blowout panels if required, dikes and berms to trap firewater and spills.

NMR Facility

Nuclear Magnetic Resonance (NMR) is the research version of the Magnetic Resonance Imaging (MRI). An NMR facility sometimes involves concrete walls and additional floor stabilization; however, with modern advances in vibration dampening and reduction in magnetic fields, this is not expected.

Synthetic Chemistry Facilities

Synthetic chemistry and process development laboratories will likely have a large number of walk-in and bench chemical fume hoods. The fume hoods necessitate additional ducting, gas distribution manifolds and plumbing, and chemical storage capability.

Animal Facility

Animal facilities are likely to include specialized washing, sanitation, and sterilization equipment, a separate HVAC system, and additional security measures. Walls, ceilings and floors will be sealed, and electrical systems will likely be required to meet electric code requirements for wet environments.

9. ASSIGNMENT AND SUBLEASE

9.1 Subtenant shall have a continuing right to assign or sublease all or a portion of the Subleased Premises, subject to prior approval of Sublandlord and Master Landlord, which approvals shall not be unreasonably withheld, conditioned or delayed. Subtenant shall provide written notice to Sublandlord as to the amount of space Subtenant elects to sublease or assign, and when Subtenant is prepared to sublease or assign such space. Sublandlord shall have the right to terminate this Sublease ("Recapture") in the event Sublandlord's consent is required and Subtenant proposes to assign this Sublease to an entity other than an Affiliate (as defined below). In addition, Sublandlord shall have the right to Recapture that portion of the Subleased Premises which Subtenant proposed to sublease to an entity which is not an Affiliate in the following circumstances: (i) the portion of the Subleased Premises which Subtenant has elected to sublease includes 10,000 rentable square feet or more of office space (as opposed to lab space); or (ii) the term for such sublease is more than 50 percent of the remainder of the Term. Sublandlord shall respond within ten (10) days of receiving such written notice from Subtenant of Sublandlord's decision to approve or disapprove of the subletting or assignment pursuant to this
Section 9. If

6

Sublandlord does not respond within such ten-day period, the non-response shall be deemed an election of Sublandlord not to Recapture the space (if applicable) and to approve such assignment or sublease and Subtenant shall have the right to proceed with the proposed subleasing or assignment subject to any approval of the Master Landlord required under the Master Lease. An Affiliate shall mean any entity or foundation which has a substantial and continuing business or philanthropic relationship with Subtenant, and may include, research partners, non-profit corporations, and joint venture partners.

9.2 Notwithstanding the foregoing to the contrary, Sublandlord's consent shall not be required for any assignment or subletting for which the Master Landlord's consent is not required under the Master Lease.

10. ALTERATIONS

Notwithstanding anything in this Sublease or the Master Lease to the contrary, Sublandlord agrees that Subtenant shall only be required to obtain Master Landlord's consent to any alterations or improvements to the Subleased Premises pursuant to Section 14 of the Master Lease and shall not be required to obtain Sublandlord's consent to any such alterations or improvements, provided that Subtenant shall provide Sublandlord with copies of all plans and specifications for any alterations or improvements concurrently with its delivery of such plans and specifications to Master Landlord for review and approval.

11. INCORPORATION BY REFERENCE

11.1 SUBJECT TO LEASE

Subject to Section 11.2 below, this Sublease is subject to all of the terms and condition of the Master Lease by and between Sublandlord and Master Landlord. Subtenant shall obtain insurance for the Subleased Premises and name Sublandlord as an additional insured in the policy.

11.2 INTERPRETATION

The terms, conditions and respective obligations of Sublandlord and Subtenant to each other under this Sublease shall be the terms and conditions of the Master Lease except for those provisions of the Master Lease which are directly contradicted by this Sublease, in which event the terms of this Sublease shall control over the Master Lease, and except for the following sections of the Master Lease which shall not apply to the Sublease: Sections 1(a) through 1(j), 1(l) through 1(n), 1(p) through 1(r), 3, 5, 6, 29 through 35, and 41 (regarding the Building Two reserved parking, provided Subtenant shall have the right to use the Building 3 reserved parking pursuant to Paragraph 6 above), and Exhibits A (pages 1 through 4), C, F and H. Therefore, for the purposes of this Sublease, wherever in the Master Lease the word "Landlord" is used it shall be deemed to mean the Sublandlord herein and wherever in the Master Lease the word "Tenant" is used it shall be deemed to mean the Subtenant herein.

7

Except as provided herein, Subtenant assumes and agrees to perform Sublandlord's obligations under the Master Lease during the Term to the extent that such obligations are applicable to the Subleased Premises, except that the obligation to pay Rent and Expenses to Master Landlord under the Master Lease shall be considered performed by Subtenant to the extent and in the amount rent is paid to Sublandlord in accordance with Section 3 of this Sublease. Subtenant shall not commit or suffer any act or omission that will violate any of the provisions of the Master Lease. Sublandlord will exercise reasonable and good faith efforts in attempting to cause Master Landlord to perform its obligations under the Master Lease for the benefit of Subtenant.

In the event of termination of the Master Lease, the Subtenant's rights and obligations for the Subleased Premises shall survive such termination and remain in full force and effect unless or until the Master Landlord and Subtenant alter the rights and obligations between them in writing; provided, however, if the Master Lease terminates as a result of the default or breach by Sublandlord or Subtenant under this Sublease, then the defaulting party shall be liable to the non-defaulting party for the damage suffered as a result of such termination. Sublandlord shall not make any election pursuant to Sections 17 or 18 of the Master Lease with respect to the Subleased Premises without Subtenant's prior written approval, which approval shall not be unreasonably withheld, conditioned, or delayed.

FIRST AMENDMENT TO SUBLEASE AGREEMENT

This First Amendment ("Amendment") is dated for reference purposes April 13, 2001, and amends that certain Sublease Agreement dated March 30, 2001 (the "Sublease") made by and between F5 Networks, Inc., a Washington corporation, as Sublandlord, and Cell Therapeutics, Inc., a Washington corporation, as Subtenant. The capitalized terms in this Amendment shall have the meaning given to those same terms in the Sublease, unless a different meaning has been provided herein.

NOW, THEREFORE, the parties hereby amend the Sublease as follows:

1. Security Deposit. The Sublease is hereby amended by deleting the second to the last sentence of Section 7. Sublandlord will apply the balance of the Subtenant's cash security deposit in the amount of sixty-five thousand eight hundred sixty-four dollars and seventy-nine cents ($65,874.79) deposited under the Prior Sublease (as defined in Section 2 of the Sublease) against the Base Rent due for the first month of the Term.
