ABGENIX, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
June 30, 2001

1. Basis of Presentation and Summary of Significant Accounting Policies

    Basis of Presentation—The unaudited condensed consolidated financial statements of Abgenix, Inc. (the "Company" or "Abgenix") included herein have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information or footnote disclosure normally included in financial statements prepared in accordance with generally accepted accounting principles has been condensed or omitted pursuant to such rules and regulations. In the opinion of the Company, the accompanying unaudited condensed consolidated financial statements contain all adjustments, consisting only of normal recurring adjustments, necessary to present fairly the financial information included therein. These financial statements should be read in conjunction with the audited financial statements for the year ended December 31, 2000 and accompanying notes included in the Company's Annual Report as filed on Form 10-K with the Securities and Exchange Commission. The results of operations for the three and six months ended June 30, 2001 are not necessarily indicative of the results to be expected for the full year or for any other future period.

    Revenue Recognition—The Company receives payments from customers for licenses, options and services. These payments are generally non-refundable but are reported as deferred revenue until they are recognizable as revenue. The Company has followed the following principles in recognizing revenue:

    Research license fees: Fees to license the use of the Company's proprietary XenoMouseR technology in research performed by customers of the Company are generally recognized only after the license period has commenced and the technology has been delivered. If Abgenix is obligated to provide significant assistance to enable the customer to utilize the license, the revenue is recognized over the period of such obligation.

    Product license fees: Fees to license the production, use and sale of an antibody generated by the XenoMouse technology are generally recognized only after the license period has commenced and the technology has been delivered. If Abgenix is obligated to provide significant assistance to enable the customer to utilize the license, the revenue is recognized over the period of such obligation.

    Option fees: Fees for granting options to customers to obtain a license to develop a product are recognized as revenue when the option is exercised or when the option period expires, whichever occurs first.

    Payments for research services performed by Abgenix are recognized ratably over the period during which these services are performed. However, fees earned for research services under co-development arrangements are recorded as contract revenues in the period services are rendered, net of fees payable by Abgenix to such co-developers for reimbursements of research and development costs.

    Milestone payments are recognized as revenue when the milestone is achieved.

    Earnings per Share—Net loss per share is based on the weighted average common shares outstanding. Potentially dilutive securities have been excluded from the computation, as their effect is antidilutive.

3. Acquisition of Abgenix Biopharma Inc. (formerly known as ImmGenics Pharmaceuticals, Inc.)

    In November 2000, the Company acquired all of the voting stock of Abgenix Biopharma Inc. (formerly known as ImmGenics Pharmaceuticals Inc.), a Canadian biotechnology company. Under the terms of the agreement, Abgenix Biopharma special shares were issued to former common and preferred shareholders and debenture holders of Abgenix Biopharma. The holders of the Abgenix Biopharma special shares have the right to put their shares to the Company for cash at $4.97 per share. In February 2001, the Company notified the holders of the special shares that the purchase price would be settled in cash. The put rights will expire on March 31, 2002. As of June 30, 2001, approximately 13.5 million Abgenix Biopharma special shares had been exchanged for $67.0 million and approximately 200,000 special shares were still outstanding.

    In connection with the acquisition, the Company agreed to exchange Abgenix Biopharma stock options held by employees and directors of Abgenix Biopharma for stock options of the Company, based on an exchange ratio that entitled the holder of each Abgenix Biopharma option to receive a replacement option for Company shares having a total value (less the total exercise price) not exceeding the total value of Abgenix Biopharma shares underlying the Abgenix Biopharma option (less the total exercise price), as fixed in November 2000 when the Abgenix Biopharma options were terminated. Replacement options covering a total of 247,155 shares of common stock of the Company were issued in exchange for the Abgenix Biopharma options. The replacement options were fully vested at the time of the exchange. Pursuant to the Company's stock option plan, the Company also offered the employees and certain former directors of Abgenix Biopharma a cash buy-out election. As of June 30, 2001, option holders had exercised their cash buy-out rights in respect of options for 137,073 Company shares pursuant to which a total of $4.1 million in cash was paid. In addition, options representing 84,009 Company shares had been exercised as of that date. As of August 1, 2001, options for an additional 22,340 shares had been cashed out for $724,286, options covering 3,733 shares had been exercised, and no options remained outstanding.

4. Facility Lease and Letter of Credit

    In February 2001, the Company signed an operating lease for an additional facility for research and development activities. The lease expires in April 2011. As a condition to the lease, the Company provided a stand-by letter of credit for $3.0 million to the lessor as security for the Company's obligations under the lease. The letter of credit is secured by $3.3 million of cash and marketable securities in an investment account that the Company must maintain for the term of the lease. The investment account is classified as deposits and other assets on the balance sheet. Future minimum payments under this non-cancelable operating lease are as follows (in thousands): 2001—$1,485; 2002—$3,049; 2003—$3,171; 2004—$3,298; 2005—$3,430; and $20,732 over the remaining term of the lease.

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 contains forward-looking statements based upon current expectations that involve risks and uncertainties. When used in this quarterly report on Form 10-Q, the words "intend," "anticipate," "believe," "estimate," "plan" and "expect" and similar expressions as they relate to Abgenix are included to identify forward-looking statements. 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 below and under the heading "Additional factors that might affect future results".

Overview

    We are a biopharmaceutical company that develops and intends to commercialize antibody therapeutic products for the treatment of a variety of disease conditions, including transplant-related diseases, inflammatory and autoimmune disorders, cardiovascular disease, infectious diseases and cancer. We have proprietary technologies that facilitate rapid generation of highly specific, fully human antibody product candidates that bind to disease targets appropriate for antibody therapy. We developed our XenoMouseR technology, a technology utilizing genetically modified mice. We are also the exclusive licensee of a technology that enables the rapid identification of antibodies with desired function and characteristics, referred to as SLAM technology. In our newly developed XenoMax™ technology, we use SLAM technology to select and isolate antibodies with particular function and characteristics from antibody-producing cells generated by XenoMouse animals. We believe XenoMax technology enhances our capabilities in product development and flexibility in manufacturing. We intend to use XenoMouse technology to build a large and diversified product portfolio that we expect to develop and commercialize through licensing arrangements with pharmaceutical companies and others, through joint development and through internal product development programs. We have entered into a variety of contractual arrangements with multiple pharmaceutical, biotechnology and genomics companies involving our XenoMouse technology. Two of our customers, Pfizer, Inc. and Amgen, Inc., have initiated clinical trials with XenoMouse-generated antibodies. In addition, we have three proprietary antibody product candidates currently in clinical trials, two of which we have agreed to co-develop and commercialize with others.

    As of June 30, 2001, we had entered into contracts covering numerous antigen targets with twenty-seven customers to use our XenoMouse technology to produce and/or develop the resulting fully human antibodies. Pursuant to these contracts, we and our customers intend to generate antibody product candidates for the treatment of cancer, inflammation, autoimmune diseases, transplant rejection, cardiovascular disease, growth factor modulation, neurological diseases and infectious diseases. We expect that substantially all of our revenues for the foreseeable future will result from payments under these and other contracts. The terms of these arrangements vary, but can generally be categorized as follows:

    Antigen Target Sourcing Contracts—We have entered into several target sourcing contracts with genomics and biopharmaceutical companies that may enable us to generate a pipeline of proprietary fully human antibody product candidates. Typically, these contracts provide for Abgenix to make fully human antibodies to the antigen targets provided or identified by the contract counterparty. The contracts typically contain provisions that allow either Abgenix or the other contract party to evaluate and select particular antibodies from the pool of generated antibodies for further development and commercialization. The party selecting a product candidate for further development or commercialization will generally pay to the other party license fees, milestone payments and royalty payments on any eventual product sales, in exchange for rights to develop and commercialize the product.

9


    Proprietary Product Development—In July and August 2000, we entered into two joint development and commercialization agreements. The first is with Immunex Corporation for ABX-EGF, a fully human antibody created by us. Under the agreement, Immunex paid us an initial license fee at signing and a second license fee in May 2001. Development costs will be shared equally, as would any profits from sales of collaboration products. We and Immunex share responsibility for product development. We will be responsible for completing the ongoing Phase I trials, and if the Phase I trials are successful, both companies will share responsibility for the execution of Phase II trials across a variety of indications. Immunex will have primary responsibility for Phase III clinical trials and will market any potential product, while we will retain co-promotion rights. The second agreement is with SangStat Medical Corporation for ABX-CBL, an antibody developed by us. Under that agreement, SangStat paid us an initial license fee in 2000 and a second milestone payment in June 2001, and has agreed to make a final milestone payment in 2002. Development costs will be shared equally, as would any profits from sales of collaboration products. We and SangStat share responsibility for product development, including the ongoing Phase II/III clinical trials. SangStat will market any potential product and we will be responsible for manufacturing ABX-CBL.

    Technology Licensing—We also license our XenoMouse technology to third parties for the purpose of generating fully human antibody product candidates to one or more specific antigen targets provided by the customer. In most cases, we provide our mice to the customers who then carry out immunizations with their specific antigen targets. In other cases, we immunize the mice with the customers' antigen targets for additional compensation. The customer generally has an option for a period of time to acquire a product license for any antibody product identified using XenoMouse technology that the customer wishes to develop and commercialize. The financial terms of these agreements may include license fees, option fees and milestone payments paid to us by the customers. Based on our agreements, these payments and fees would average $8.0 to $10.0 million per antigen target if our customer takes the antibody product candidate into development and ultimately to commercialization. Additionally, our license agreements entitle us to receive royalties on any future product sales by the customer.

    Our dependence on contracts with third parties subjects us to a number of risks and uncertainties. Agreements with licensees typically allow the licensees significant discretion in electing whether to pursue any of the planned activities. We cannot control the amount or timing of resources our licensees may devote to the product candidates. Even if we fulfill our obligations under an agreement, the licensee can terminate the agreement at any time following proper written notice. If any licensee were to terminate or breach its agreement with us, or otherwise fail to complete its obligations in a timely manner, our business, financial condition and results of operations may be materially harmed.

    We have three proprietary antibody product candidates that are currently in clinical trials, two of which are now being co-developed with our collaborators, as follows:

    ABX-IL8—Generated using XenoMouse technology, ABX-IL8 is our fully human antibody candidate for the treatment of inflammatory diseases, including psoriasis and rheumatoid arthritis. The status of clinical trials for ABX-IL8 is as follows:

    Psoriasis—We have completed Phase I, Phase I/II and Phase IIa clinical trials. We initiated a Phase IIb clinical trial in February 2001 and enrollment is ongoing.

    Rheumatoid arthritis—We initiated a Phase IIa clinical trial in December 2000. Enrollment is complete and patient treatment is ongoing.

    ABX-EGF—Generated using XenoMouse technology, ABX-EGF is our fully human antibody candidate for the treatment of a variety of cancers. In July 2000, we entered into the joint

10


      development and commercialization agreement with Immunex Corporation for ABX-EGF described above. The status of clinical trials for ABX-EGF is as follows:

      Various Cancers—We initiated a Phase I clinical trial for ABX-EGF in cancer in July 1999 and enrollment is ongoing.

      Kidney cancer—We initiated a Phase II clinical trial for ABX-EGF in kidney cancer in April 2001 and enrollment is ongoing. In May 2001, we received the second milestone payment from Immunex contemplated by the agreement described above.

      Non-small cell lung cancer—Immunex initiated a Phase II clinical trial for ABX-EGF in non-small cell lung cancer in combination with standard chemotherapy, compared to standard chemotherapy alone, in July 2001 and enrollment is ongoing.

    ABX-CBL—We developed ABX-CBL, an in-licensed mouse antibody, for the treatment of a transplant-related disease known as graft versus host disease, or GVHD. We have completed a multi-center Phase II clinical trial for ABX-CBL and initiated a Phase II/III clinical trial in December 1999 in which enrollment is ongoing. In August 2000, we entered into the joint development and commercialization agreement with SangStat Medical Corporation for ABX-CBL described above.

    We will expend significant capital to conduct clinical trials for our proprietary product candidates, including several Phase II clinical trials we have initiated or plan to initiate in 2001. We believe that more extensive clinical data will enable us to enter into additional contractual arrangements related to those proprietary product candidates. We expect that this will substantially increase our capital needs over the next few years and increase our operating losses. However, we believe that we will be able to receive more favorable proceeds from our contract parties if we have completed significant development of these products.

    In addition to our proprietary antibody product candidates in clinical trials, there are two customer-developed antibodies generated with XenoMouse technology in clinical trials as follows:

    Pfizer, Inc.—We generated a XenoMouse-derived antibody for treating cancer, which Pfizer has advanced into clinical trials.

    Amgen, Inc.—We generated a XenoMouse-derived antibody for treating an undisclosed antigen target, which Amgen has advanced into clinical trials.

Internal Development Activities

    We intend to build our product portfolio by using our XenoMouse and XenoMax technologies to generate antibodies to antigen targets that we source, self-funding clinical activities to determine preliminary safety and efficacy, and entering into more development and commercialization agreements with pharmaceutical and biotechnology companies. We plan to enter into agreements to use our XenoMax technology to assist our licensees and collaborators in isolating antibodies with desired functions and characteristics. These arrangements may or may not involve joint sharing of costs and profits.

    Contract revenue totaled $8.4 million and $12.5 million in the three and six-month periods ended June 30, 2001 compared to $3.5 million and $5.4 million, respectively, in the comparable 2000 periods. The primary components for both periods were as follows:

    Proprietary Product Development

      A total of $6.4 and $9.0 million was recognized in the three and six-month periods ended June 30, 2001, including license fees, reimbursement of development costs and milestone fees under joint development and commercialization agreements with Immunex Corporation and SangStat Medical Corporation for the development of ABX-EGF and ABX-CBL, respectively. As the agreements were executed in the third quarter of 2000, no revenue was recognized related to these agreements in the comparable three and six-month periods ended June 30, 2000. Under these agreements, we recognize license fees ratably over the minimum periods we are obligated to share in development costs. Under the Immunex agreement, this is the 17-month period ended December 31, 2001. Under the SangStat agreement, this was the 6-month period ended January 31, 2001.

    Technology Licensing

      A total of $2.0 and $3.5 million was recognized in the three and six-month periods ended June 30, 2001, including license fees, research fees, option fees and milestone fees primarily from Amgen Inc., Pfizer, Inc., Centocor, Inc., CuraGen Corporation and Chiron Corporation. Included in these amounts was a milestone fee from Amgen Inc. for the advancement of a XenoMouse derived antibody into clinical trials.

      A total of $3.5 and $5.4 was recognized in the three and six-month periods ended June 30, 2000, including license fees, research fees and option fees primarily from Millennium Pharmaceutical Inc., Pfizer, Inc., Japan Tobacco Inc. and CuraGen Corporation. The primary component of this revenue was research and license fees related to an agreement with Millennium Pharmaceuticals Inc. in which we granted several licenses to make, use and sell antibodies generated with our XenoMouse technology. Payments totaling $10.0 million were received in the first quarter of 2000 representing a research license fee, product license fees and service fees to establish XenoMouse technology at Millennium. We recognized these fees ratably each month over the period ended December 31, 2000, during which we fulfilled our obligation to assist in establishing XenoMouse technology at Millennium, enabling Millennium to practice the research license and product licenses. No such fees were recognized in the three and six-month periods ended June 30, 2001.

    Interest and other income consist primarily of interest from cash, cash equivalents and marketable securities. Interest and other income decreased to $7.7 million in the three months ended June 30, 2001 compared to $8.8 million in the same period in 2000. Interest and other income increased to $18.0 million in the six-month period ended June 30, 2001 compared to $13.1 million in the same period in 2000. Interest and other income in the second quarter of 2001 decreased $2.6 million compared to the first quarter of 2001. The decrease in interest and other income for the three months ended June 30, 2001 compared to the same period one year ago and the decrease in interest and other income sequentially from the first quarter of 2001 was primarily due to lower cash, marketable securities and cash equivalent balances as well as lower interest rates. The increase in interest and other income for the six months ended June 30, 2001 compared to the same period in 2000 is the result of higher average balances of our marketable securities and cash equivalents as a result of the investment of $717.1 million of net proceeds from a follow-on offering in February 2000 and a private placement in November 2000.

    Research and development expenses consist primarily of compensation and other expenses related to research and development personnel; costs associated with pre-clinical testing and clinical trials of our product candidates, including the costs of manufacturing the product candidates; and facilities expenses. Research and development expenses increased to $25.6 million in the three months ended June 30, 2001 from $11.9 million in the comparable period in 2000 and to $42.4 million in the six months ended June 30, 2001 from $19.1 million in the comparable period in 2000. The increase is primarily due to costs associated with the following:

Increased Personnel—Staffing at June 30, 2001 increased by approximately 141% from June 30, 2000. The increase in staff is to support the increased level of product development activities, including new target validation, process sciences, manufacturing and clinical activities. Also, the increase includes additional employees resulting from our acquisition of our Canadian subsidiary, Abgenix Biopharma Inc. in November 2000. Included in the increase are salary, related fringe benefits, and recruiting and relocation costs. We expect personnel costs to increase further as we continue to build our organization.

Facility Costs—Related to the increased staffing, we acquired new facilities and related leasehold improvements, furniture and fixtures. As a result, rent, depreciation and utilities have increased in the three and six-month periods ended June 30, 2001 as compared to the same periods in 2000. We expect facility costs to increase in future periods as a result of our capital expansion plans.

Research Costs—In the first quarter of 2001, we entered into an agreement with Impath Inc. under which Impath will evaluate target expression by performing certain tissue studies, enabling us to better identify potential diagnostic and therapeutic products. The agreement includes a monthly fee payable over 13 months. Also, research costs and lab supplies costs have increased in the first quarter of 2001 in comparison to the first quarter of 2000 as a result of the acquisition of Abgenix Biopharma as well as increased research activity and staff in the United States.

Clinical Costs—Clinical costs have increased in 2001 as we have initiated new clinical trials and progressed to later stage clinical trials for our three product candidates, ABX-CBL, ABX-IL8 and ABX-EGF. The costs of such trials include the clinical investigator site fees, monitoring costs and data management costs. Additionally, such costs include the costs of manufacturing the antibody used in clinical trials. In July and August 2000, we entered into separate agreements with Immunex and SangStat to share equally in the costs of developing and commercializing ABX-EGF and ABX-CBL, respectively. However, we expect clinical costs will increase in the future as we enter additional clinical trials for both new and existing product candidates.

Toxicology Costs—Related to our increased clinical trial activity, we incurred higher costs for toxicology studies in the three and six-month periods ended June 30, 2001 in comparison to the comparable periods in 2000.

    Amortization of intangible assets relates to existing technology (including patents and certain royalty rights), goodwill and assembled workforce acquired through the acquisitions of Abgenix Biopharma and IntraImmune Therapies Inc. in November 2000 and Xenotech in December 1999. As a result of the acquisitions in 2000, amortization increased to $2.0 million in the three months ended June 30, 2001 from $0.8 million in the comparable period in 2000 and to $4.1 million in the six months ended June 30, 2001 from $1.6 million in the comparable period in 2000.

    General and administrative expenses include compensation and other expenses related to finance and administrative personnel, professional services and facilities. General and administrative expenses increased to $3.1 million in the three months ended June 30, 2001 from $1.8 million in the comparable period in 2000 and to $6.2 million in the six months ended June 30, 2001 from $3.4 million in the comparable period in 2000. The increase reflects increased personnel costs, including recruiting costs and incentive compensation and additional consulting costs associated with our Information Services group. The increase is also related to the acquisition of Abgenix Biopharma. We expect personnel costs to increase further as we continue to build our organization, including consulting costs associated with new information systems.

Liquidity and Capital Resources

    At June 30, 2001, we had cash, cash equivalents and marketable securities of approximately $575.4 million. We invest our cash equivalents and marketable securities in highly liquid, interest bearing, investment grade and government securities in order to preserve principal.

    Net cash used in operating activities was $14.1 million for the six months ended June 30, 2001, and net cash provided by operating activities was $1.4 million for the six months ended June 30, 2000. The increased use of cash in operations reflects primarily our increased funding of research and development and manufacturing costs related to the development of new products. Total research and development expenses increased $23.3 million in the six months ended June 30, 2001 from the comparable period in 2000. Also affecting the increased use of cash in operations in the six months ended June 30, 2001, was the timing of customer payments. Customers provided cash of $10.3 million in the six months ended June 30, 2001 in comparison to $17.8 million in the six months ended June 30, 2000, both net of the change in accounts receivable and deferred revenue. Additionally, cash was used in the six months ended June 30, 2001 for a security deposit related to a new facility lease. Partially offsetting the increased use of cash was interest income. Cash provided by interest income was $21.6 million in the six months ended June 30, 2001 in comparison to $8.3 million in the six months ended June 30, 2000, both net of the change in interest receivable.

    Net cash used in investing activities was $68.7 million and $389.0 million for the six months ended June 30, 2001, and June 30, 2000, respectively. For the six months ended June 30, 2001, we received cash from our investment activities as certain of our marketable securities matured in comparison to the six months ended June 30, 2000, in which cash received from our follow-on public offering in February 2000 was invested in marketable securities. Cash was also used in the six months ended June 30, 2001, as follows: $67.0 million to the holders of Abgenix Biopharma special shares in connection with our acquisition of Abgenix Biopharma; $4.1 million for the buy-out of certain stock options issued in connection with the Abgenix Biopharma acquisition; $20.1 million for the acquisition of property and equipment, primarily leasehold improvements related to our new facility and computer equipment; and $15.0 million for an equity investment in MDS Proteomics Inc. In the six months ended June 30, 2000, $1.7 million was spent on property and equipment, primarily leasehold improvements related to our new facility and computer equipment.

    During the six months ended June 30, 2001, net cash provided by financing activities was $2.8 million, consisting of proceeds from the exercise of stock options. This activity compares to the six months ended June 30, 2000, in which net cash provided by financing activities was $498.8 million, consisting primarily of the proceeds of our follow-on public offering in February 2000, in which we raised $496.5 million. In addition to this funding, in 2000 we received $3.8 million from the exercise of warrants and stock options and proceeds from the issuance of stock under our employee stock purchase plan.

    In March 2000 and February 2001, we obtained stand-by letters of credit for $2.0 and $3.0 million, respectively, from a commercial bank as security for our obligations on the leases on our two new leased facilities. The stand-by letters of credit are secured by an investment account, in which we must maintain a $5.5 million balance. Additionally, in 1997 we leased $2.0 million of our laboratory and office equipment from a financing company. The lease term is 48 months. The lease bears interest at approximately 12.5%, and matures in September 2001. We also had a construction financing line with a bank in the amount of $4.3 million that was used to finance construction of leasehold improvements at our first facility. The line was paid off in May 2000.

    We plan to continue to make significant expenditures to establish our own manufacturing facility and expand our research and development activities, including pre-clinical product development and clinical trials. We will also continue to look for new technology suppliers as potential acquisitions or alliance collaborators. Over the next eighteen months, we estimate that we will spend approximately

14


$180.0-$200.0 million on leasehold improvements and equipment for our new manufacturing and research and development facilities. Additionally, we expect to spend approximately $10.0-$20.0 million on new computer hardware and software, including the acquisition of a new enterprise resource planning system. We also plan to spend significant amounts to develop, on a proprietary or co-developed basis, investigational new drug applications (INDs) for up to three product candidates annually, beginning in 2002. We believe that the annual goals of our customers and collaborators for 2002 and beyond include up to five INDs for additional product candidates based on our XenoMouse technology. If unforeseen difficulties arise in the course of developing product candidates, obtaining needed licenses, manufacturing product candidates, performing pre-clinical development and clinical trials of such product candidates, obtaining necessary regulatory approvals, or in other aspects of our business, we may be required to make further substantial expenditures. Our future liquidity and capital requirements will depend on many factors, including:

    the scope and results of pre-clinical testing and clinical trials;

    the retention of existing and establishment of further licensing and other agreements, if any;

    continued scientific progress in our research and development programs;

    the size and complexity of these programs;

    the cost of establishing our manufacturing capabilities;

    the cost of conducting commercialization activities and arrangements;

    the time and expense involved in seeking regulatory approvals;

    competing technological and market developments;

    the time and expense of filing and prosecuting patent applications and enforcing patent claims;

    our investment in, or acquisition of, other companies;

    the amount of product in-licensing in which we engage; and

    other factors not within our control.

    We believe that our current cash balances, cash equivalents, marketable securities, and the cash generated from our licensing and contractual agreements will be sufficient to meet our operating and capital requirements for at least one year. We may choose to obtain additional financing from time to time. We may choose to raise additional funds through public or private financing, licensing and contractual agreements or other arrangements. We cannot be sure that any additional funding, if needed, will be available on terms favorable to us. Furthermore, any additional equity financing may be dilutive to our shareholders, and debt financing, if available, may involve restrictive covenants. We may also choose to obtain funding through licensing and other contractual agreements. Such agreements may require us to relinquish our rights to certain of our technologies, products or marketing territories. Our failure to raise capital when needed would harm our business, financial condition and results of operations.

    We have incurred net losses in each of the last five years of operation, including net losses of $7.1 million in 1996, $35.9 million in 1997, $16.8 million in 1998, $20.5 million in 1999, $8.8 million in 2000 and $22.4 million in the six months ended June 30, 2001. As of June 30, 2001, our accumulated deficit was $121.0 million. Our losses to date have resulted principally from:

    research and development costs relating to the development of our XenoMouse technology and antibody product candidates;

    costs associated with certain agreements with Japan Tobacco and certain 1997 settlement and cross-licensing agreements with GenPharm International, Inc.;

15


    in-process research and development costs and amortization of intangible assets associated with our acquisitions of Abgenix Biopharma, IntraImmune Therapies and Xenotech;

    general and administrative costs relating to our operations.

    We expect to incur additional losses for the foreseeable future as a result of increases in our research and development costs, including costs associated with conducting pre-clinical development and clinical trials, and charges related to purchases of technology or other assets, and costs associated with establishing our manufacturing facilities. We intend to invest significantly in our products prior to entering into licensing agreements. This may increase our need for capital and will result in losses for several years. We expect that the amount of operating losses will fluctuate significantly from quarter to quarter as a result of increases or decreases in our research and development efforts, the execution or termination of licensing and contractual agreements, and the initiation, success or failure of clinical trials.

    As of December 31, 2000, we had federal net operating loss carryforwards of approximately $148.0 million. Our net operating loss carryforwards exclude losses incurred prior to our formation in July 1996. Further, the amounts associated with the 1997 cross-license and settlement that have been expensed for financial statement accounting purposes have been capitalized and are being amortized over a period of approximately 15 years for tax purposes. The net operating loss and credit carryforwards will expire in the years 2011 through 2020, if not utilized. Utilization of the net operating losses and credits may be subject to a substantial annual limitation due to the "change in ownership" provisions of the Internal Revenue Code of 1986 and similar state provisions. The annual limitation may result in the expiration of net operating losses and credits before utilization.

ADDITIONAL FACTORS THAT MIGHT AFFECT FUTURE RESULTS

Risks Related to the Development and Commercialization of our Products

Our XenoMouse and XenoMax technologies may not produce safe, efficacious or commercially viable products.

    Our XenoMouse and XenoMax technologies are new approaches to the generation of antibody therapeutic products. We have not commercialized any antibody products based on our technologies. Moreover, we are not aware of any commercialized, fully human antibody therapeutic products that have been generated from any technologies similar to ours. Our antibody product candidates are still at an early stage of development. Clinical trials have begun with respect to only three fully human antibody product candidates generated by XenoMouse technology. We cannot be certain that either XenoMouse technology or XenoMax technology will generate antibodies against every antigen to which they are exposed in an efficient and timely manner, if at all. Furthermore, XenoMouse technology and XenoMax technology may not result in any meaningful benefits to our current or potential customers or in product candidates that are safe and efficacious for patients. If our technologies fail to generate antibody product candidates that lead to the successful development and commercialization of products, our business, financial condition and results of operations will be materially harmed.

Successful development of our products is uncertain.

    Our development of current and future product candidates, either alone or in conjunction with collaborators, is subject to the risks of failure inherent in the development of new pharmaceutical products and products based on new technologies. These risks include:

    delays in product development, clinical testing or manufacturing;

    unplanned expenditures in product development, clinical testing or manufacturing;

    failure in clinical trials or failure to receive regulatory approvals;

16


    emergence of superior or equivalent products;

    inability to manufacture on our own, or through others, product candidates on a commercial scale;

    inability to market products due to third-party proprietary rights;

    election by our customers not to pursue product development;

    failure by our customers to develop products successfully; and

    failure to achieve market acceptance.

    Because of these risks, our research and development efforts and those of our customers and collaborators may not result in any commercially viable products. If a significant portion of these development efforts is not successfully completed, required regulatory approvals are not obtained or any approved products are not commercially successful, our business, financial condition and results of operations will be materially harmed.

Clinical trials for our product candidates will be expensive and their outcome is uncertain.

    Conducting clinical trials is a lengthy, time-consuming and expensive process. Before obtaining regulatory approvals for the commercial sale of any products, we must demonstrate through pre-clinical testing and clinical trials that our product candidates are safe and effective for use in humans. We will incur substantial expense for, and devote a significant amount of time to, pre-clinical testing and clinical trials.

    Historically, the results from pre-clinical testing and early clinical trials have often not been predictive of results obtained in later clinical trials. A number of new drugs and biologics have shown promising results in clinical trials, but subsequently failed to establish sufficient safety and efficacy data to obtain necessary regulatory approvals. Data obtained from pre-clinical and clinical activities are susceptible to varying interpretations, which may delay, limit or prevent regulatory approval. In addition, regulatory delays or rejections may be encountered as a result of many factors, including changes in regulatory policy during the period of product development.

    As of June 30, 2001 three of our proprietary product candidates, ABX-CBL, ABX-IL8 and ABX-EGF, were in clinical trials. Patient follow-up for these clinical trials has been limited. To date, data obtained from these clinical trials has been insufficient to demonstrate safety and efficacy under applicable Federal Drug Administration, or FDA, guidelines. As a result, this data will not support an application for regulatory approval without further clinical trials. Clinical trials conducted by us or by third parties on our behalf may not demonstrate sufficient safety and efficacy to obtain the requisite regulatory approvals for ABX-CBL, ABX-IL8, ABX-EGF or any other potential product candidates. Regulatory authorities may not permit us to undertake any additional clinical trials for our product candidates.

    In addition, our other product candidates are in pre-clinical development, but we have not submitted investigational new drug applications nor begun clinical trials for these product candidates. Our pre-clinical or clinical development efforts may not be successfully completed, we may not file further investigational new drug applications and clinical trials may not commence as planned.

    Completion of clinical trials may take several years or more. The length of time generally varies substantially according to the type, complexity, novelty and intended use of the product candidate. Our commencement and rate of completion of clinical trials may be delayed by many factors, including:

    inability to manufacture sufficient quantities of materials for use in clinical trials;

    slower than expected rate of patient recruitment;

17


    inability to adequately follow patients after treatment;

    unforeseen safety issues;

    lack of efficacy during the clinical trials; or

    government or regulatory delays.

    We have limited experience in conducting and managing clinical trials. We rely on third parties, including our customers, to assist us in managing and monitoring clinical trials. Our reliance on these third parties may result in delays in completing, or in failure to complete, these trials if the third parties fail to perform under our agreements with them.

    Our product candidates may fail to demonstrate safety and efficacy in clinical trials. This failure may delay development of other product candidates and hinder our ability to conduct related pre-clinical testing and clinical trials. As a result of these failures, we may also be unable to obtain additional financing. Any delays in, or termination of, our clinical trials could materially harm our business, financial condition and results of operations.

We currently rely on a sole source third-party manufacturer.

    We currently rely, and will continue to rely for at least the next five years, on a single contract manufacturer, Lonza Biologics (Lonza), to produce ABX-CBL, ABX-IL8 and ABX-EGF under good manufacturing practice regulations, for use in our clinical trials. In December 2000, we entered into a manufacturing supply agreement with Lonza, under which Lonza will make available exclusively to us, for a period of five years, a cell culture production suite, with associated purification capacity, within Lonza's facility. As a result of this agreement, we expect to gain access to production capacity and scheduling flexibility similar to owning the production capability, while Lonza retains responsibility for staffing and operating the facility. The term of the agreement is five years with an option to extend the term. The dedicated cell culture production suite is being refurbished and is expected to be operational and available to us in the third quarter of 2001. Lonza has a limited number of facilities in which our product candidates can be produced and has limited experience in manufacturing ABX-CBL, ABX-IL8 and ABX-EGF in quantities sufficient for conducting clinical trials or for commercialization. We currently rely on Lonza to produce our product candidates under good manufacturing practice regulations, which meet acceptable standards for our clinical trials.

    Third-party manufacturers may encounter difficulties in scaling up production, including problems involving production yields, quality control and assurance, shortage of qualified personnel, compliance with FDA regulations, production costs, and development of advanced manufacturing techniques and process controls. Our third-party manufacturer may not perform as agreed or may not remain in the contract manufacturing business for the time required by us to successfully produce and market our product candidates. If our third-party manufacturer fails to deliver the required quantities of our product candidates for clinical use on a timely basis and at commercially reasonable prices, and we fail to find a replacement manufacturer or develop our own manufacturing capabilities, our business, financial condition and results of operations will be materially harmed.

Our own ability to manufacture is uncertain.

    We are building our own manufacturing facility for the manufacture of products for clinical trials and early commercial launch, in compliance with FDA good manufacturing practices. In May 2000, we signed a long-term lease for a building to contain this manufacturing facility. Construction has started and this facility is expected to be operational by year-end 2002. The costs of the facility, including design, leasehold improvements and equipment, will approximate $140 million. Construction of this facility may take longer than expected, and the planned and actual construction costs of building and qualifying the facility for regulatory compliance may be higher than expected. The process of

18


manufacturing antibody products is complex. We have no experience in the clinical or commercial scale manufacturing of ABX-CBL, ABX-IL8 and ABX-EGF, or any other antibody products. Such antibody products will also need to be manufactured in a facility and by a process that comply with FDA and other regulations. It may take a substantial period of time to begin producing antibodies in compliance with such regulations. Our manufacturing operations will be subject to ongoing, periodic unannounced inspection by the FDA and state agencies to ensure compliance with good manufacturing practices. If we are unable to establish and maintain a manufacturing facility within our planned time and cost parameters, the development and sales of our products and our financial performance may be materially harmed.

    We also may encounter problems with the following:

    production yields;

    quality control and assurance;

    shortages of qualified personnel;

    on-going compliance with FDA regulations;

    production costs; and

    development of advanced manufacturing techniques and process controls.

    We are currently evaluating our options for commercial production of our antibody products, which include use of third-party manufacturers, establishing our own commercial scale manufacturing facility or entering into a manufacturing joint venture relationship with a third party. We are aware of only a limited number of companies on a worldwide basis who operate manufacturing faclilities in which our product candidates can be manufactured under good manufacturing practice regulations, a requirement for all pharmaceutical products. It would take a substantial period of time for a contract manufacturing facility that has not been producing antibodies to begin producing antibodies under good manufacturing practice regulations. We may not be able to contract with any of these companies on acceptable terms, if at all.

    In addition, we and any third-party manufacturer will be required to register with the FDA and other regulatory authorities any manufacturing facilities in which our antibody products are manufactured. The facilities will then be subject to inspections confirming compliance with FDA good manufacturing practice or other regulations. If we or any of our third-party manufacturers fail to maintain regulatory compliance, our business, financial condition and results of operations will be materially harmed.

We will need to find third parties to license and develop many of our product candidates.

    Our strategy for the development and commercialization of antibody therapeutic products depends, in large part, upon the formation of collaboration agreements with third parties. Potential third parties include pharmaceutical and biotechnology companies, academic institutions and other entities. We must enter into these agreements to successfully develop and commercialize product candidates. These agreements are necessary in order for us to:

    access proprietary antigens for which we can generate fully human antibody products;

    fund our research and development activities;

    fund pre-clinical development, clinical trials and manufacturing;

    seek and obtain regulatory approvals; and

    successfully commercialize existing and future product candidates.

19


    Only a limited number of fully human antibody product candidates have been generated pursuant to our collaboration agreements, and only four antibody product candidates generated with XenoMouse technology have entered clinical testing. These product candidates may not result in commercially successful products. Current or future collaboration agreements may not be successful. If we fail to maintain our existing collaboration agreements or to enter into additional agreements, our business, financial condition and results of operations could be materially harmed.

    Our dependence on licensing and other agreements with third parties subjects us to a number of risks. These agreements may not be on terms that prove favorable to us, and collaborators typically are afforded significant discretion in electing whether to pursue any of the planned activities. Licensing and other contractual agreements may require us to relinquish our rights to certain of our technologies, products or marketing territories. We cannot control the amount or timing of resources our collaborators may devote to the product candidates, and collaborators may not perform their obligations as expected. Additionally, business combinations or significant changes in a collaborator's business strategy may adversely affect a collaborator's willingness or ability to complete its obligations under the arrangement. Even if we fulfill our obligations under an agreement, typically our collaborators can terminate the agreement at any time following proper written notice. If any of our collaborators were to terminate or breach our agreement, or otherwise fail to complete its obligations in a timely manner, our business, financial condition and results of operations may be materially harmed. If we are not able to establish further collaboration agreements or any or all of our existing agreements are terminated, we may be required to seek new collaborators or to undertake product development and commercialization at our own expense. Such an undertaking may:

    limit the number of product candidates that we will be able to develop and commercialize;

    reduce the likelihood of successful product introduction;

    significantly increase our capital requirements; and

    place additional strain on our management's time.

    Existing or future collaborators may pursue alternative technologies, including those of our competitors. Disputes may arise with respect to the ownership of rights to any technology or products developed with any current or future collaborator. Lengthy negotiations with potential new collaborators or disagreements between us and our collaborators may lead to delays or termination in the research, development or commercialization of product candidates or result in time-consuming and expensive litigation or arbitration. If any of our collaborators pursue alternative technologies or fail to develop or commercialize successfully any product candidate to which they have obtained rights from us, our business, financial condition and results of operations may be materially harmed.

We do not have marketing and sales experience.

    We do not have marketing, sales or distribution experience or capability. For certain products, we may establish an internal marketing and sales force. We intend to enter into arrangements with third parties to market and sell most of our products. We may not be able to enter into marketing and sales arrangements with others on acceptable terms, if at all. To the extent that we enter into marketing and sales arrangements with other companies, our revenues, if any, will depend on the efforts of others. These efforts may not be successful. If we are unable to enter into third-party arrangements, then we must develop a marketing and sales force, which may need to be substantial in size, in order to achieve commercial success for any product candidate approved by the FDA. We may not successfully develop marketing and sales capabilities or have sufficient resources to do so. If we do develop such capabilities, we will compete with other companies that have experienced and well-funded marketing and sales operations. If we fail to establish successful marketing and sales capabilities or fail to enter into successful marketing arrangements with third parties, our business, financial condition and results of operations will be materially harmed.

20


We are subject to extensive government regulation and we may not be able to obtain regulatory approvals.

    Our product candidates under development are subject to extensive and rigorous domestic government regulation. The FDA regulates, among other things, the development, testing, manufacture, safety, efficacy, record-keeping, labeling, storage, approval, advertising, promotion, sale and distribution of biopharmaceutical products. If our products are marketed abroad, they also are subject to extensive regulation by foreign governments. None of our product candidates has been approved for sale in the United States or any foreign market. The regulatory review and approval process, which includes pre-clinical studies and clinical trials of each product candidate, is lengthy, expensive and uncertain. Securing FDA approval requires the submission of extensive pre-clinical and clinical data and supporting information to the FDA for each indication to establish the product candidates' safety and efficacy. The approval process takes many years, requires the expenditure of substantial resources, involves post-marketing surveillance, and may involve ongoing requirements for post-marketing studies. Regulatory requirements are subject to frequent change. Delays in obtaining regulatory approvals may:

    adversely affect the successful commercialization of any drugs that we or our customers develop;

    impose costly procedures on us or our customers;

    diminish any competitive advantages that we or our customers may attain; and

    adversely affect our receipt of revenues or royalties.

    Certain material changes to an approved product such as manufacturing changes or additional labeling claims are subject to further FDA review and approval. Any required approvals, once obtained, may be withdrawn. Compliance with other regulatory requirements may not be maintained. Further, if we fail to comply with applicable FDA and other regulatory requirements at any stage during the regulatory process, we or our third-party manufacturers may be subject to sanctions, including:

    delays;

    warning letters;

    fines;

    product recalls or seizures;

    injunctions;

    refusal of the FDA to review pending market approval applications or supplements to approval applications;

    total or partial suspension of production;

    civil penalties;

    withdrawals of previously approved marketing applications; and

    criminal prosecutions.

    We expect to rely on our customers to file investigational new drug applications and generally direct the regulatory approval process for many of our products. Our customers may not be able to conduct clinical testing or obtain necessary approvals from the FDA or other regulatory authorities for any product candidates. If we fail to obtain required governmental approvals, our customers will experience delays in or be precluded from marketing products developed through our research. In addition, the commercial use of our products will be precluded. Delays and limitations may materially harm our business, financial condition and results of operations.

21


    We and our third-party manufacturers also are required to comply with the applicable FDA current good manufacturing practice regulations. Good manufacturing practice regulations include requirements relating to quality control and quality assurance as well as the corresponding maintenance of records and documentation. Manufacturing facilities are subject to inspection by the FDA. These facilities must be approved before we can use them in commercial manufacturing of our products. We or our third-party manufacturers may not be able to comply with the applicable good manufacturing practice requirements and other FDA regulatory requirements. If we or our third-party manufacturers fail to comply, our business, financial condition and results of operations will be materially harmed.

Market acceptance of our products is uncertain.

    Our product candidates may not gain market acceptance among physicians, patients, healthcare payors and the medical community. We may not achieve market acceptance even if clinical trials demonstrate safety and efficacy, and the necessary regulatory and reimbursement approvals are obtained. The degree of market acceptance of any product candidates that we develop will depend on a number of factors, including:

    establishment and demonstration of clinical efficacy and safety;

    cost-effectiveness of our product candidates;

    their potential advantage over alternative treatment methods;

    reimbursement policies of government and third-party payors; and

    marketing and distribution support for our product candidates, including the efforts of our collaborators where they have marketing and distribution responsibilities.

    Physicians will not recommend therapies using our products until such time as clinical data or other factors demonstrate the safety and efficacy of such procedures as compared to conventional drug and other treatments. Even if the clinical safety and efficacy of therapies using our antibody products is established, physicians may elect not to recommend the therapies for any number of other reasons, including whether the mode of administration of our antibody products is effective for certain indications. For example, antibody products are typically administered by infusion or injection, which requires substantial cost and inconvenience to patients. Our product candidates, if successfully developed, will compete with a number of drugs and therapies manufactured and marketed by major pharmaceutical and other biotechnology companies. Our products may also compete with new products currently under development by others. Physicians, patients, third-party payors and the medical community may not accept and utilize any product candidates that we or our customers develop. If our products do not achieve significant market acceptance, our business, financial condition and results of operations will be materially harmed.

Risks Related to our Finances

We are an early stage company.

    You must evaluate us in light of the uncertainties and complexities present in an early stage biopharmaceutical company. Our product candidates are in early stages of development. We will require significant additional investment in research and development, pre-clinical testing and clinical trials, and regulatory and sales and marketing activities to commercialize current and future product candidates. Our product candidates, if successfully developed, may not generate sufficient or sustainable revenues to enable us to be profitable.

22


We have a history of losses.

    We have incurred net losses in each of the last five years of operation, including net losses of $7.1 million in 1996, $35.9 million in 1997, $16.8 million in 1998, $20.5 million in 1999, $8.8 million in 2000 and $22.4 million in the six months ended June 30, 2001. As of June 30, 2001, our accumulated deficit was $121.0 million. Our losses to date have resulted principally from:

    research and development costs relating to the development of our XenoMouse technology and antibody product candidates;

    costs associated with certain agreements with Japan Tobacco and certain 1997 settlement and cross-licensing agreements with GenPharm International, Inc.;

    in-process research and development costs and amortization of intangible assets associated with our acquisitions of Abgenix Biopharma, IntraImmune Therapies and Xenotech;

    general and administrative costs relating to our operations.

    We expect to incur additional losses for the foreseeable future as a result of increases in our research and development costs, including costs associated with conducting pre-clinical development and clinical trials, and charges related to purchases of technology or other assets. We intend to invest significantly in our products prior to entering into licensing agreements. This will increase our need for capital and will result in losses for several years. We expect that the amount of operating losses will fluctuate significantly from quarter to quarter as a result of increases or decreases in our research and development efforts, the execution or termination of licensing and contractual agreements, and the initiation, success or failure of clinical trials.

Our future profitability is uncertain.

    Prior to June 1996, our business was owned by Cell Genesys, Inc. and operated as a business unit of Cell Genesys. Since that time, we have funded our research and development activities primarily from private placements and public offerings of our securities and from revenues generated by our licensing and contractual agreements.

    We expect that substantially all of our revenues for the foreseeable future will result from payments under licensing and other contractual arrangements and from interest income. To date, payments under licensing and other agreements have been in the form of option fees, reimbursement for research and development expenses, license fees and milestone payments. Payments under our existing and any future customer agreements will be subject to significant fluctuation in both timing and amount. Our revenues may not be indicative of our future performance or of our ability to continue to achieve such milestones. Our revenues and results of operations for any period may also not be comparable to the revenues or results of operations for any other period. We may not be able to:

    enter into further licensing and other agreements;

    successfully complete pre-clinical development or clinical trials;

    obtain required regulatory approvals;

    successfully develop, manufacture and market product candidates; or

    generate additional revenues or profitability.

    If we fail to achieve any of the above goals, our business, financial condition and results of operations will be materially harmed.

23


We may require additional financing.

    We will continue to expend substantial resources for the expansion of research and development, including costs associated with conducting pre-clinical development and clinical trials. We will be required to expend substantial funds in the course of completing required additional development, pre-clinical testing and clinical trials of and regulatory approval for product candidates. Our future liquidity and capital requirements will depend on many factors, including:

    the scope and results of pre-clinical development and clinical trials;

    the retention of existing and establishment of further licensing and other agreements, if any;

    continued scientific progress in our research and development programs;

    the size and complexity of these programs;

    the cost of establishing manufacturing capabilities and conducting commercialization activities and arrangements;

    the time and expense involved in seeking regulatory approvals;

    competing technological and market developments;

    the time and expense of filing and prosecuting patent applications and enforcing patent claims;

    our investment in, or acquisition of, other companies;

    the amount of product in-licensing in which we engage; and

    other factors not within our control.

    We believe that our current cash balances, cash equivalents, marketable securities, and the cash generated from our licensing and contractual agreements will be sufficient to meet our operating and capital requirements for at least one year. We may choose to obtain additional financing from time to time. We may choose to raise additional funds through public or private financing, licensing and contractual agreements or other arrangements. We cannot be sure that any additional funding, if needed, will be available on terms favorable to us. Furthermore, any additional equity financing may be dilutive to our shareholders, and debt financing, if available, may involve restrictive covenants. We may also choose to obtain funding through licensing and other contractual agreements. Such agreements may require us to relinquish our rights to certain of our technologies, products or marketing territories. Our failure to raise capital when needed would harm our business, financial condition and results of operations.

Risks Related to our Intellectual Property

Our patent position is uncertain and our success depends on our proprietary rights.

    Our success depends in part on our ability to:

    obtain patents;

    protect trade secrets;

    operate without infringing the proprietary rights of others; and

    prevent others from infringing our proprietary rights.

    We will be able to protect our proprietary rights from unauthorized use by third parties only to the extent that our proprietary rights are covered by valid and enforceable patents or are effectively maintained as trade secrets. We own six issued patents in the United States, one granted patent in Europe, and three granted patents in Japan, and we have several pending patent applications in the

24


United States and abroad, each of which relates to XenoMouse technology and products generated by it. Our wholly owned subsidiary, Xenotech, owns two issued U.S. patents, one Australian patent, and several pending U.S. and foreign patent applications related to methods of treatment of bone disease in cancer patients. Our wholly owned subsidiary, Abgenix Biopharma, is exclusively licensed under one issued U.S. patent and one pending patent application in Canada and Europe relating to the Selected Lymphocyte Antibody Method ("SLAM") technology. Our wholly owned subsidiary, IntraImmune Therapies, is licensed under patents and pending applications in the United States and in Europe related to intrabody technology. In addition, we have seven issued U.S. patents and several pending patent applications in the United States and abroad that are jointly owned with Japan Tobacco relating to antibody technology or genetic manipulation. We attempt to protect our proprietary position by filing U.S. and foreign patent applications related to our proprietary technology, inventions and improvements that are important to the development of our business. However, the patent position of biopharmaceutical companies involves complex legal and factual questions, and, therefore, enforceability cannot be predicted with certainty. Patents, if issued, may be challenged, invalidated or circumvented. Thus, any patents that we own or license from third parties may not provide any protection against competitors. Our pending patent applications, those we may file in the future, or those we may license from third parties, may not result in patents being issued. Also, patent rights may not provide us with adequate proprietary protection or competitive advantages against competitors with similar technologies. The laws of certain foreign countries do not protect our intellectual property rights to the same extent as do the laws of the United States.

    In addition to patents, we rely on trade secrets and proprietary know-how. We seek protection, in part, through confidentiality and proprietary information agreements. These agreements may not provide meaningful protection or adequate remedies for our technology in the event of unauthorized use or disclosure of confidential and proprietary information, and, in addition, the parties may breach such agreements. Also, our trade secrets may otherwise become known to, or be independently developed by, our competitors. Furthermore, others may independently develop similar technologies or duplicate any technology that we have developed.

We may face challenges from third parties regarding the validity of our patents and proprietary rights.

    Research has been conducted for many years in the antibody and transgenic animal fields. This has resulted in a substantial number of issued patents and an even larger number of pending patent applications. The publication of discoveries in the scientific or patent literature frequently occurs substantially later than the date on which the underlying discoveries were made. Our commercial success depends significantly on our ability to operate without infringing the patents and other proprietary rights of third parties. Our technologies may unintentionally infringe the patents or violate other proprietary rights of third parties. In the event of such infringement or violation, we and our customers may be prevented from pursuing product development or commercialization. Such a result could materially harm our business, financial condition and results of operations.

    In March 1997, we entered into a cross-license and settlement agreement with GenPharm International, Inc. to avoid protracted litigation. Under the cross-license, we licensed on a non-exclusive basis certain patents, patent applications, third-party licenses and inventions pertaining to the development and use of certain transgenic rodents, including mice, that produce fully human antibodies that are integral to our products and business. Our business, financial condition and results of operations could be materially harmed if any of the parties breaches the cross-license agreement.

    We have one granted European patent relating to XenoMouse technology that is currently undergoing opposition proceedings within the European Patent Office and the outcome of this opposition is uncertain.

25


    GlaxoSmithKline, plc ("Glaxo") has a family of patents relating to certain methods for generating monoclonal antibodies that Glaxo is asserting against Genentech, Inc. in litigation that was commenced in 1999. On May 4, 2001, Genentech announced that a jury had determined that Genentech had not infringed Glaxo's patents and that all of the patent claims asserted against Genentech are invalid. We understand that Glaxo has filed a notice of appeal with the Court of Appeals for the Federal Circuit. If any of the claims of these patents are finally determined in the litigation to be valid, and if we were to use manufacturing processes covered by the patents to make our products, we may then need to obtain a license should one be available. Should a license be denied or unavailable on commercially reasonable terms, commercialization of one or more of our products could be impeded in any territories in which these claims were in force.

    Genentech, Inc. owns a U.S. patent that issued in June 1998 relating to inhibiting the growth of tumor cells that involves an anti-EGF receptor antibody in combination with a cytotoxic factor. ImClone Systems, Inc. owns or is licensed under a U.S. patent that issued in April 2001, relating to inhibiting the growth of tumor cells that involves an anti-EGF receptor antibody in combination with an anti-neoplastic agent. We believe there are strong arguments that all claims of both the Genentech patent and the ImClone patent are invalid. We are continuing to analyze the scope of these patents. We believe that currently all of the Company's activities relating to anti-EGFr monoclonal antibodies are within the exemption provided by the U.S. patent laws for uses reasonably related to obtaining FDA approval of a drug. Based on our product development plans, we do not expect the scope of our activities in this regard to change in the future prior to filing an application for a biologic license with the FDA. If the claims of either the Genentech patent or the ImClone patent are judicially determined to cover our activities with ABX-EGF and are held valid, we may be required to obtain a license to Genentech's or ImClone's patent, as the case may be, to label and sell ABX-EGF for some or all such combination indications. Should a license be denied or unavailable on commercially reasonable terms, our commercialization of ABX-EGF could be impeded in the United States.

    In 2000, the Japanese Patent Office granted a patent to Kirin Beer Kabushiki Kaisha, one of our competitors, relating to non-human transgenic mammals. Kirin has filed corresponding patent applications in Europe and Australia. Kirin may also have filed a corresponding patent application in the United States. Our licensee, Japan Tobacco, has filed opposition proceedings against the Kirin patent. We cannot predict the outcome of those opposition proceedings, which may take years to be resolved. We are analyzing the patent to determine its relevance to our business and if appropriate will analyze the scope and validity of its claims.

    The biotechnology and pharmaceutical industries have been characterized by extensive litigation regarding patents and other intellectual property rights. The defense and prosecution of intellectual property suits, United States Patent and Trademark Office interference proceedings, and related legal and administrative proceedings in the United States and internationally involve complex legal and factual questions. As a result, such proceedings are costly and time-consuming to pursue and their outcome is uncertain. Litigation may be necessary to:

    enforce patents that we own or license;

    protect trade secrets or know-how that we own or license; or

    determine the enforceability, scope and validity of the proprietary rights of others.

    If we become involved in any litigation, interference or other administrative proceedings, we could incur substantial expense and the efforts of our technical and management personnel could be significantly diverted. An adverse determination may subject us to loss of our proprietary position or to significant liabilities, or require us to seek licenses that may not be available from third parties. We may be restricted or prevented from manufacturing and selling our products, if any, in the event of an adverse determination in a judicial or administrative proceeding or if we fail to obtain necessary

26


licenses. Costs associated with these arrangements may be substantial and may include ongoing royalties. Furthermore, we may not be able to obtain the necessary licenses on satisfactory terms, if at all. These outcomes could materially harm our business, financial condition and results of operations.

Risks Related to our Industry

We face intense competition and rapid technological change.

    The biotechnology and pharmaceutical industries are highly competitive and subject to significant and rapid technological change. We are aware of several pharmaceutical and biotechnology companies that are actively engaged in research and development in areas related to antibody therapy. These companies have commenced clinical trials of antibody product candidates or have successfully commercialized antibody products. Many of these companies are addressing the same diseases and disease indications as us or our customers. Also, we compete with companies that offer antibody generation services to companies that have antigens. These competitors have specific expertise or technology related to antibody development and introduce new or modified technologies from time to time. These companies include GenPharm International, Inc., a wholly-owned subsidiary of Medarex, Inc.; Medarex's joint venture partner, Kirin Brewing Co., Ltd.; Cambridge Antibody Technology Group plc; Protein Design Labs, Inc.; and MorphoSys AG.

    Some of our competitors have received regulatory approval of or are developing or testing product candidates that may compete directly with our product candidates. For example, SangStat Medical Corp., Novartis, Pharmacia Corporation and Roche market organ transplant rejection products that may compete with ABX-CBL, which is in clinical trials. In addition, MedImmune, Inc. has a potential antibody product candidate in clinical trials for graft versus host disease that may compete with ABX-CBL. We are also aware that several companies, including Genentech, Inc. and Biogen, Inc., have potential product candidates for the treatment of psoriasis that may compete with ABX-IL8, which is in clinical trials. Furthermore, we are aware that ImClone Systems, Inc., AstraZeneca PLC, GlaxoSmithKline and a collaboration of OSI Pharmaceuticals, Inc., Genentech, Inc. and Roche have potential antibody and small molecule product candidates in clinical development that may compete with ABX-EGF, which is also in clinical trials.

    Many of these companies and institutions, either alone or together with their customers, have substantially greater financial resources and larger research and development staffs than we do. In addition, many of these competitors, either alone or together with their customers, have significantly greater experience than we do in:

    developing products;

    undertaking pre-clinical testing and human clinical trials; and

    obtaining FDA and other regulatory approvals of products.

    Accordingly, our competitors may succeed in obtaining patent protection, receiving FDA approval or commercializing products before we do. If we commence commercial product sales, we will be competing against companies with greater marketing and manufacturing capabilities, areas in which we have limited or no experience.

27


    We also face, and will continue to face, competition from academic institutions, government agencies and research institutions. There are numerous competitors working on products to treat each of the diseases for which we are seeking to develop therapeutic products. In addition, any product candidate that we successfully develop may compete with existing therapies that have long histories of safe and effective use. Competition may also arise from:

    other drug development technologies and methods of preventing or reducing the incidence of disease;

    new small molecules; or

    other classes of therapeutic agents.

    Developments by competitors may render our product candidates or technologies obsolete or non-competitive. We face and will continue to face intense competition from other companies for agreements with pharmaceutical and biotechnology companies for establishing relationships with academic and research institutions, and for licenses to proprietary technology. These competitors, either alone or with their customers, may succeed in developing technologies or products that are more effective than ours.

We face uncertainty over reimbursement and healthcare reform.

    In both domestic and foreign markets, sales of our product candidates will depend in part upon the availability of reimbursement from third-party payors. Such third-party payors include government health administration authorities, managed care providers, private health insurers and other organizations. These third-party payors are increasingly challenging the price and examining the cost effectiveness of medical products and services. In addition, significant uncertainty exists as to the reimbursement status of newly approved healthcare products. We may need to conduct post-marketing studies in order to demonstrate the cost-effectiveness of our products. Such studies may require us to provide a significant amount of resources. Our product candidates may not be considered cost-effective. Adequate third-party reimbursement may not be available to enable us to maintain price levels sufficient to realize an appropriate return on our investment in product development. Domestic and foreign governments continue to propose and pass legislation designed to reduce the cost of healthcare. Accordingly, legislation and regulations affecting the pricing of pharmaceuticals may change before our proposed products are approved for marketing. Adoption of such legislation could further limit reimbursement for pharmaceuticals. If the government and third-party payors fail to provide adequate coverage and reimbursement rates for our product candidates, the market acceptance of our products may be adversely affected. If our products do not receive market acceptance, our business, financial condition and results of operations will be materially harmed.

Other Risks Related to our Company

We acquired Abgenix Biopharma Inc., a Vancouver-based biotechnology company in November 2000. We may experience difficulty in the integration of this acquisition, or any future acquisition, with the operations of our business.

    In early November, we acquired all of the voting stock of Abgenix Biopharma, a Canadian biotechnology company that develops and intends to commercialize antibody-based therapeutic and diagnostic products for the treatment and diagnosis of a variety of diseases, for an aggregate consideration of approximately $77.2 million.

    We have a limited history of operating the business of our company and Abgenix Biopharma on a consolidated basis, and we have no prior experience operating a business outside of the United States. We may have difficulty integrating Abgenix Biopharma's research and development operations with our

28


own. Difficulty managing the integration of Abgenix Biopharma could result from many factors, some of which are beyond our control, including the following:

    the geographic distance between our Fremont, California headquarters and our acquired Vancouver, British Columbia subsidiary;

    potential differences in research and development protocols between Abgenix Biopharma and ourselves; and

    the potential loss of personnel from our acquired operations.

    In the future, we may from time to time seek to expand our business through additional corporate acquisitions. Our acquisition of companies and businesses and expansion of operations, involve risks such as the following:

    the potential inability to identify target companies best suited to our business plan;

    the potential inability to successfully integrate acquired operations and businesses and to realize anticipated synergies, economies of scale or other expected value;

    incurrence of expenses attendant to transactions that may or may not be consummated; and

    difficulties in managing and coordinating operations at multiple venues, which, among other things, could divert our management's attention from other important business matters.

    In addition, our acquisition of companies and businesses and expansion of operations, including the recent acquisition of Abgenix Biopharma, may result in dilutive issuances of equity securities, the incurrence of additional debt, large one-time write-offs and the creation of goodwill or other intangible assets that could result in amortization expense.

We depend on key personnel and must continue to attract and retain key employees and consultants.

    We are highly dependent on the principal members of our scientific and management staff. For us to pursue product development, marketing and commercialization plans, we will need to hire additional qualified scientific personnel to perform research and development. We will also need to hire personnel with expertise in clinical testing, government regulation, manufacturing, marketing and finance. Attracting and retaining qualified personnel will be critical to our success. We may not be able to attract and retain personnel on acceptable terms given the competition for such personnel among biotechnology, pharmaceutical and healthcare companies, universities and non-profit research institutions. If we lose any of these persons, or are unable to attract and retain qualified personnel, our business, financial condition and results of operations may be materially harmed.

    In addition, we rely on members of our Scientific Advisory Board and other consultants to assist us in formulating our research and development strategy. All of our consultants and the members of our Scientific Advisory Board are employed by other entities. They may have commitments to, or advisory or consulting agreements with, other entities that may limit their availability to us. If we lose the services of these advisors, the achievement of our development objectives may be impeded. Such impediments may materially harm our business, financial condition and results of operations.

We have implemented a stockholder rights plan and are subject to other anti-takeover provisions.

    In June 1999, our board of directors adopted a stockholder rights plan, which was amended in November 1999. The stockholder rights plan and certain provisions of our amended and restated certificate of incorporation and amended and restated bylaws may have the effect of making it more difficult for a third party to acquire, or of discouraging a third party from attempting to acquire, control of us. This could limit the price that certain investors might be willing to pay in the future for

29


our common stock. Certain provisions of our amended and restated certificate of incorporation and amended and restated bylaws allow us to:

    issue preferred stock without any vote or further action by the stockholders;

    eliminate the right of stockholders to act by written consent without a meeting;

    specify procedures for director nominations by stockholders and submission of other proposals for consideration at stockholder meetings; and

    eliminate cumulative voting in the election of directors.

    We are subject to certain provisions of Delaware law which could also delay or make more difficult a merger, tender offer or proxy contest involving us. In particular, Section 203 of the Delaware General Corporation Law prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years unless certain conditions are met. The stockholder rights plan, the possible issuance of preferred stock, the procedures required for director nominations and stockholder proposals and Delaware law could have the effect of delaying, deferring or preventing a change in control of us, including, without limitation, discouraging a proxy contest or making more difficult the acquisition of a substantial block of our common stock. The provisions could also limit the price that investors might be willing to pay in the future for shares of our common stock.

We face product liability risks and may not be able to obtain adequate insurance.

    The use of any of our product candidates in clinical trials, and the sale of any approved products, may expose us to liability claims resulting from such use or sale of our products. These claims might be made directly by consumers, healthcare providers or by pharmaceutical companies or others selling such products. We may experience financial losses in the future due to product liability claims. We have obtained limited product liability insurance coverage for our clinical trials, under which the coverage limits are $5.0 million per occurrence and $5.0 million in the aggregate. We intend to expand our insurance coverage to include the sale of commercial products if marketing approval is obtained for product candidates in development. We may not be able to maintain insurance coverage at a reasonable cost or in sufficient amounts to protect us against losses. If a successful product liability claim or series of claims is brought against us for uninsured liabilities or in excess of insured liabilities, our business, financial condition and results of operations may be materially harmed.

Our operations involve hazardous materials.

    Our research and manufacturing activities involve the controlled use of hazardous materials. We cannot eliminate the risk of accidental contamination or injury from these materials. In the event of an accident or environmental discharge, we may be held liable for any resulting damages, which may exceed our financial resources and may materially harm our business, financial condition and results of operations.

We do not intend to pay cash dividends on our common stock.

    We intend to retain any future earnings to finance the growth and development of our business and we do not plan to pay cash dividends on our common stock in the foreseeable future.

Our stock price is highly volatile.

    The market price and trading volume of our common stock are volatile, and we expect such volatility to continue for the foreseeable future. For example, during the period between June 30, 2000 and June 30, 2001, our common stock closed as high as $93.1875 per share and as low as $16.75 per

30


share. This may impact your decision to buy or sell our common stock. Factors affecting our stock price include:

    our financial results;

    fluctuations in our operating results;

    announcements of technological innovations or new commercial therapeutic products by us or our competitors;

    published reports by securities analysts;

    progress with clinical trials;

    government regulation;

    changes in reimbursement policies;

    developments in patent or other proprietary rights;

    developments in our relationship with customers;

    public concern as to the safety and efficacy of our products; and

    general market conditions.

The state of California is currently experiencing a shortage of electrical energy that may cause certain of our operations to be suspended temporarily.

    Substantially all of our operations in Fremont, California are run by electrical energy purchased from a local utility. We have not experienced energy shortages and do not anticipate any significant difficulties in the foreseeable future. We have limited back-up generating capacity. Extended shortages of energy could slow our research efforts and increase our operating costs.


ITEM 3—Quantitative and Qualitative Disclosures about Market Risk.

    Interest Rate Risk. The objective of our investment activities is to preserve principal, while at the same time maximizing yields without significantly increasing risk. To achieve this objective, we invest in highly liquid and high quality debt securities. Our investments in debt securities are subject to interest rate risk. To minimize the exposure due to an adverse shift in interest rates, we invest in short-term securities and our goal is to maintain an average maturity of approximately one year. A hypothetical 1.0% per annum increase in interest rates would result in a decrease in the fair market value of our debt securities of approximately $1.0 million, at June 30, 2001 and approximately $1.1 million, at December 31, 2000.

    Equity Price Risk. We are exposed to equity price risk on strategic investments in CuraGen Corporation and Immunogen, Inc. We typically do not attempt to reduce or eliminate our market exposure on these securities. With respect to CuraGen and Immunogen, each of whose common stock trades on public exchanges, assuming an adverse change of 30% in the market price of their stock, the fair value of our equity investments would decrease in value by approximately $29.6 million and $23.8 million as of June 30, 2001 and December 31, 2000, respectively. This estimate is not necessarily indicative of future performance and actual results may differ materially.

ARTICLE I
CORPORATE OFFICES

1.1 REGISTERED OFFICE

    The registered office of the corporation shall be fixed in the certificate of incorporation of the corporation.

1.2 OTHER OFFICES

    The board of directors may at any time establish branch or subordinate offices at any place or places where the corporation is qualified to do business.

ARTICLE II
MEETINGS OF STOCKHOLDERS

2.1 PLACE OF MEETINGS

    Meetings of stockholders shall be held at any place within or outside the State of Delaware designated by the board of directors. In the absence of any such designation, stockholders' meetings shall be held at the principal executive office of the corporation.

2.2 ANNUAL MEETING

    The annual meeting of stockholders shall be held each year on a date and at a time designated by the board of directors. In the absence of such designation, the annual meeting of stockholders shall be held on the last Wednesday of May in each year at 10:00 a.m. However, if such day falls on a legal holiday, then the meeting shall be held at the same time and place on the next succeeding full business day. At the meeting, directors shall be elected, and any other proper business may be transacted.

2.3 SPECIAL MEETING

    A special meeting of the stockholders may be called at any time by the board of directors, by the chairman of the board, or by the chief executive officer. If a special meeting is called by any person or persons other than the board of directors, then the request shall be in writing, specifying the time of such meeting and the general nature of the business proposed to be transacted, and shall be delivered personally or sent by registered mail or by telegraphic or other facsimile transmission to the chairman of the board, the chief executive officer, or the secretary of the corporation. The officer receiving the request shall cause notice to be promptly given to the stockholders entitled to vote, in accordance with the provisions of Sections 2.4 and 2.6 of these Amended and Restated Bylaws, that a meeting will be held at the time requested by the person or persons calling the meeting, so long as that time is not less than thirty-five (35) nor more than sixty (60) days after the receipt of the request. If the notice is not given within twenty (20) days after receipt of the request, then the person or persons requesting the meeting may give the notice. Nothing contained in this paragraph of this Section 2.3 shall be construed as limiting, fixing or affecting the time when a meeting of stockholders called by action of the board of directors may be held.

2.4 NOTICE OF STOCKHOLDERS' MEETINGS

    All notices of meetings of stockholders shall be sent or otherwise given in accordance with Section 2.6 of these Amended and Restated Bylaws not less than ten (10) nor more than sixty (60) days before the date of the meeting. The notice shall specify the place, date and hour of the meeting and (i) in the case of a special meeting, the purpose or purposes for which the meeting is called (no business other than that specified in the notice may be transacted) or (ii) in the case of the annual

3


meeting, those matters which the board of directors, at the time of giving the notice, intends to present for action by the stockholders (but any proper matter may be presented at the meeting for such action). The notice of any meeting at which directors are to be elected shall include the name of any nominee or nominees who, at the time of the notice, the board intends to present for election.

2.5 ADVANCE NOTICE OF STOCKHOLDER NOMINEES AND STOCKHOLDER BUSINESS

    Subject to the rights of holders of any class or series of stock having a preference over the Common Stock as to dividends or upon liquidation, (a) nominations for the election of directors, and (b) business proposed to be brought before any stockholder meeting may be made by the board of directors or proxy committee appointed by the board of directors or by any stockholder entitled to vote in the election of directors generally if such nomination or business proposed is otherwise proper business before such meeting. However, any such stockholder may nominate one or more persons for election as directors at a meeting or propose business to be brought before a meeting, or both, only if such stockholder has given timely notice in proper written form of their intent to make such nomination or nominations or to propose such business. To be timely, such stockholder's notice must be delivered to or mailed and received at the principal executive offices of the corporation not less than one hundred twenty (120) calendar days in advance of the date specified in the corporation's proxy statement released to stockholders in connection with the previous year's annual meeting of stockholders; provided, however, that in the event that no annual meeting was held in the previous year or the date of the annual meeting has been changed by more than thirty (30) days from the date contemplated at the time of the previous year's proxy statement, notice by the stockholder to be timely must be so received a reasonable time before the solicitation is made. To be in proper form, a stockholder's notice to the secretary shall set forth: (i) the name and address of the stockholder who intends to make the nominations or propose the business and, as the case may be, of the person or persons to be nominated or of the business to be proposed; (ii) a representation that the stockholder is a holder of record of stock of the corporation entitled to vote at such meeting and, if applicable, intends to appear in person or by proxy at the meeting to nominate the person or persons specified in the notice; (iii) if applicable, a description of all arrangements or understandings between the stockholder and each nominee and any other person or persons (naming such person or persons) pursuant to which the nomination or nominations are to be made by the stockholder; (iv) such other information regarding each nominee or each matter of business to be proposed by such stockholder as would be required to be included in a proxy statement filed pursuant to the proxy rules of the Securities and Exchange Commission had the nominee been nominated, or intended to be nominated, or the matter been proposed, or intended to be proposed by the board of directors; and (v) if applicable, the consent of each nominee to serve as director of the corporation if so elected. The chairman of the meeting shall refuse to acknowledge the nomination of any person or the proposal of any business not made in compliance with the foregoing procedure.

2.6 MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE

    Written notice of any meeting of stockholders shall be given either personally or by first-class mail or by telegraphic or other written communication. Notices not personally delivered shall be sent charges prepaid and shall be addressed to the stockholder at the address of that stockholder appearing on the books of the corporation or given by the stockholder to the corporation for the purpose of notice. Notice shall be deemed to have been given at the time when delivered personally or deposited in the mail or sent by telegram or other means of written communication. An affidavit of the mailing or other means of giving any notice of any stockholders' meeting, executed by the secretary, assistant secretary or any transfer agent of the corporation giving the notice, shall be prima facie evidence of the giving of such notice.

4


2.7 QUORUM

    The holders of a majority in voting power of the stock issued and outstanding and entitled to vote thereat, present in person or represented by proxy, shall constitute a quorum at all meetings of the stock holders for the transaction of business except as otherwise provided by statute or by the certificate of incorporation. If, however, such quorum is not present or represented at any meeting of the stockholders, then either (i) the chairman of the meeting or (ii) the stockholders entitled to vote thereat, present in person or represented by proxy, shall have power to adjourn the meeting in accordance with Section 2.7 of these Amended and Restated Bylaws. When a quorum is present at any meeting, the vote of the holders of a majority of the stock having voting power present in person or represented by proxy shall decide any question brought before such meeting, unless the question is one upon which, by express provision of the laws of the State of Delaware or of the certificate of incorporation or these Amended and Restated Bylaws, a different vote is required, in which case such express provision shall govern and control the decision of the question. If a quorum be initially present, the stockholders may continue to transact business until adjournment, notwithstanding the withdrawal of enough stockholders to leave less than a quorum, if any action taken is approved by a majority of the stockholders initially constituting the quorum.

2.8 ADJOURNED MEETING; NOTICE

    When a meeting is adjourned to another time and place, unless these Amended and Restated Bylaws otherwise require, notice need not be given of the adjourned meeting if the time and place thereof are announced at the meeting at which the adjournment is taken. At the adjourned meeting the corporation may transact any business that might have been transacted at the original meeting. If the adjournment is for more than thirty (30) days, or if after the adjournment a new record date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting.

2.9 VOTING

    The stockholders entitled to vote at any meeting of stockholders shall be determined in accordance with the provisions of Section 2.11 of these Amended and Restated Bylaws, subject to the provisions of Sections 217 and 218 of the General Corporation Law of Delaware (relating to voting rights of fiduciaries, pledgors and joint owners, and to voting trusts and other voting agreements). Except as may be otherwise provided in the certificate of incorporation or these Amended and Restated Bylaws, each stockholder shall be entitled to one vote for each share of capital stock held by such stockholder and stockholders shall not be entitled to cumulate their votes in the election of directors or with respect to any matter submitted to a vote of the stockholders. Notwithstanding the foregoing, if the stockholders of the corporation are entitled, pursuant to Sections 2115 and 301.5 of the California Corporations Code, to cumulate their votes in the election of directors, each such stockholder shall be entitled to cumulate votes (i.e., cast for any candidate a number of votes greater than the number of votes that such stockholder normally is entitled to cast) only if the candidates' names have been properly placed in nomination (in accordance with these Amended and Restated Bylaws) prior to commencement of the voting, and the stockholder requesting cumulative voting has given notice prior to commencement of the voting of the stockholder's intention to cumulate votes. If cumulative voting is properly requested, each holder of stock, or of any class or classes or of a series or series thereof, who elects to cumulate votes shall be entitled to as many votes as equals the number of votes that (absent this provision as to cumulative voting) he or she would be entitled to cast for the election of directors with respect to his or her shares of stock multiplied by the number of directors to be elected by him, and he or she may cast all of such votes for a single director or may distribute them among the number to be voted for, or for any two or more of them, as he or she may see fit.

5


2.10 STOCKHOLDER ACTION BY WRITTEN CONSENT WITHOUT A MEETING

    Unless otherwise provided in the Certificate of Incorporation, any action required or permitted to be taken at any annual or special meeting of stockholders may be taken without a meeting, without prior notice and without a vote, if a consent or consents in writing setting forth the action so taken, shall be signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted. Such consents shall be delivered to the corporation by delivery to it registered office in the state of Delaware, its principal place of business, or an officer or agent of the corporation having custody of the book in which proceedings of meetings of stockholders are recorded. Delivery made to a corporation's registered office shall be by hand or by certified or registered mail, return receipt requested.

2.11 RECORD DATE FOR STOCKHOLDER NOTICE; VOTING

    For purposes of determining the stockholders entitled to notice of any meeting or to vote thereat, the board of directors may fix, in advance, a record date, which shall not precede the date upon which the resolution fixing the record date is adopted by the board of directors and which shall not be more than sixty (60) days nor less than ten (10) days before the date of any such meeting, and in such event only stockholders of record on the date so fixed are entitled to notice and to vote, notwithstanding any transfer of any shares on the books of the corporation after the record date. If the board of directors does not so fix a record date, the record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be at the close of business on the business day next preceding the day on which notice is given, or, if notice is waived, at the close of business on the business day next preceding the day on which the meeting is held. A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting unless the board of directors fixes a new record date for the adjourned meeting, but the board of directors shall fix a new record date if the meeting is adjourned for more than thirty (30) days from the date set for the original meeting. The record date for any other purpose shall be as provided in Section 8.1 of these Amended and Restated Bylaws.

2.12 PROXIES

    Every person entitled to vote for directors, or on any other matter, shall have the right to do so either in person or by one or more agents authorized by a written proxy signed by the person and filed with the secretary of the corporation, but no such proxy shall be voted or acted upon after three (3) years from its date, unless the proxy provides for a longer period. A proxy shall be deemed signed if the stockholder's name is placed on the proxy (whether by manual signature, typewriting, telegraphic transmission, telefacsimile or otherwise) by the stockholder or the stockholder's attorney-in-fact. The revocability of a proxy that states on its face that it is irrevocable shall be governed by the provisions of Section 212(e) of the General Corporation Law of Delaware.

2.13 ORGANIZATION

    The chief executive officer, or in the absence of the chief executive officer, the chairman of the board, or, in the absence of the chief executive officer and the chairman of the board, the president, or in the absence of the chief executive officer, the chairman of the board, and the president, one of the corporation's vice presidents, shall call the meeting of the stockholders to order, and shall act as chairman of the meeting. In the absence of the chief executive officer, the chairman of the board, the president, and all of the vice presidents, the stockholders shall appoint a chairman for such meeting. The chairman of any meeting of stockholders shall determine the order of business and the procedures at the meeting, including such matters as the regulation of the manner of voting and the conduct of business. The secretary of the corporation shall act as secretary of all meetings of the stockholders, but

6


in the absence of the secretary at any meeting of the stockholders, the chairman of the meeting may appoint any person to act as secretary of the meeting.

2.14 LIST OF STOCKHOLDERS ENTITLED TO VOTE

    The officer who has charge of the stock ledger of the corporation shall prepare and make, at least ten (10) days before every meeting of stockholders, a complete list of the stockholders entitled to vote at the meeting, arranged in alphabetical order, and showing the address of each stockholder and the number of shares registered in the name of each stockholder. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting, during ordinary business hours, for a period of at least ten (10) days prior to the meeting, either at a place within the city where the meeting is to be held, which place shall be specified in the notice of the meeting, or, if not so specified, at the place where the meeting is to be held. The list shall also be produced and kept at the time and place of the meeting during the whole time thereof, and may be inspected by any stockholder who is present.

2.15 WAIVER OF NOTICE

    Whenever notice is required to be given under any provision of the General Corporation Law of Delaware or of the certificate of incorporation or these Amended and Restated Bylaws, a written waiver thereof, signed by the person entitled to notice, whether before or after the time stated therein,shall be deemed equivalent to notice. Attendance of a person at a meeting shall constitute a waiver of notice of such meeting, except when the person attends a meeting for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened. Neither the business to be transacted at, nor the purpose of, any regular or special meeting of the stockholders need be specified in any written waiver of notice unless so required by the certificate of incorporation or these Amended and Restated Bylaws.

ARTICLE III
DIRECTORS

3.1 POWERS

    Subject to the provisions of the General Corporation Law of Delaware and to any limitations in the Certificate of Incorporation or these Amended and Restated Bylaws relating to action required to be approved by the stockholders or by the outstanding shares, the business and affairs of the corporation shall be managed and all corporate powers shall be exercised by or under the direction of the board of directors.

3.2 NUMBER OF DIRECTORS

    The number of members of the board of directors shall be as determined by the board of directors. No reduction of the authorized number of directors shall have the effect of removing any director before that director's term of office expires.

3.3 ELECTION AND TERM OF OFFICE OF DIRECTORS

    Except as provided in Section 3.4 of these Amended and Restated Bylaws, directors shall be elected at each annual meeting of stockholders to hold office until the next annual meeting. Each director, including a director elected or appointed to fill a vacancy, shall hold office until the expiration of the term for which elected and until a successor has been elected and qualified.

3.4 RESIGNATION AND VACANCIES

    Any director may resign effective on giving written notice to the chairman of the board, the chief executive officer, the secretary or the board of directors, unless the notice specifies a later time for that resignation to become effective. If the resignation of a director is effective at a future time, the board

7


of directors may elect a successor to take office when the resignation becomes effective. Vacancies in the board of directors may be filled by a majority of the remaining directors, even if less than a quorum, or by a sole remaining director; however, a vacancy created by the removal of a director by the vote of the stockholders or by court order may be filled only by the affirmative vote of a majority of the shares represented and voting at a duly held meeting at which a quorum is present (which shares voting affirmatively also constitute a majority of the required quorum). Each director so elected shall hold office until the next annual meeting of the stockholders and until a successor has been elected and qualified. Unless otherwise provided in the certificate of incorporation or these Amended and Restated Bylaws: (i) Vacancies and newly created directorships resulting from any increase in the authorized number of directors elected by all of the stockholders having the right to vote as a single class may be filled by a majority of the directors then in office, although less than a quorum, or by a sole remaining director. (ii) Whenever the holders of any class or classes of stock or series thereof are entitled to elect one or more directors by the provisions of the certificate of incorporation, vacancies and newly created directorships of such class or classes or series may be filled by a majority of the directors elected by such class or classes or series thereof then in office, or by a sole remaining director so elected. If at any time, by reason of death or resignation or other cause, the corporation should have no directors in office, then any officer or any stockholder or an executor, administrator, trustee or guardian of a stockholder, or other fiduciary entrusted with like responsibility for the person or estate of a stockholder, may call a special meeting of stockholders in accordance with the provisions of the certificate of incorporation or these Amended and Restated Bylaws, or may apply to the Court of Chancery for a decree summarily ordering an election as provided in Section 211 of the General Corporation Law of Delaware. If, at the time of filling any vacancy or any newly created directorship, the directors then in office constitute less than a majority of the whole board (as constituted immediately prior to any such increase), then the Court of Chancery may, upon application of any stockholder or stockholders holding at least ten (10) percent of the total number of the shares at the time outstanding having the right to vote for such directors, summarily order an election to be held to fill any such vacancies or newly created directorships, or to replace the directors chosen by the directors then in office as aforesaid, which election shall be governed by the provisions of Section 211 of the General Corporation Law of Delaware as far as applicable.

3.5 REMOVAL OF DIRECTORS

    Unless otherwise restricted by statute, by the certificate of incorporation or by these Amended and Restated Bylaws, any director or the entire board of directors may be removed, with or without cause, by the holders of a majority of the shares then entitled to vote at an election of directors; provided, however, that, if and so long as stockholders of the corporation are entitled to cumulative voting, if less than the entire board is to be removed, no director may be removed without cause if the votes cast against his removal would be sufficient to elect him if then cumulatively voted at an election of the entire board of directors.

3.6 PLACE OF MEETINGS; MEETINGS BY TELEPHONE

    Regular meetings of the board of directors may be held at any place within or outside the State of Delaware that has been designated from time to time by resolution of the board. In the absence of such a designation, regular meetings shall be held at the principal executive office of the corporation. Special meetings of the board may be held at any place within or outside the State of Delaware that has been designated in the notice of the meeting or, if not stated in the notice or if there is no notice, at the principal executive office of the corporation. Any meeting of the board, regular or special, may be held by conference telephone or similar communication equipment, so long as all directors participating in the meeting can hear one another; and all such participating directors shall be deemed to be present in person at the meeting.

8


3.7 FIRST MEETINGS

    The first meeting of each newly elected board of directors shall be held at such time and place as shall be fixed by the vote of the stockholders at the annual meeting. In the event of the failure of the stockholders to fix the time or place of such first meeting of the newly elected board of directors, or in the event such meeting is not held at the time and place so fixed by the stockholders, the meeting may be held at such time and place as shall be specified in a notice given as hereinafter provided for special meetings of the board of directors, or as shall be specified in a written waiver signed by all of the directors.

3.8 REGULAR MEETINGS

    Regular meetings of the board of directors may be held without notice at such time as shall from time to time be determined by the board of directors. If any regular meeting day shall fall on a legal holiday, then the meeting shall be held at the same time and place on the next succeeding full business day.

3.9 SPECIAL MEETINGS; NOTICE

    Special meetings of the board of directors for any purpose or purposes may be called at any time by the chairman of the board, the chief executive officer, the president, any vice president, the secretary or any two directors. Notice of the time and place of special meetings shall be delivered personally or by telephone to each director or sent by first-class mail, telecopy or telegram, charges prepaid, addressed to each director at that director's address as it is shown on the records of the corporation. If the notice is mailed, it shall be deposited in the United States mail at least four (4) days before the time of the holding of the meeting. If the notice is delivered personally or by telephone, telecopy or telegram, it shall be delivered personally or by telephone or to the telegraph company at least forty-eight (48) hours before the time of the holding of the meeting. Any oral notice given personally or by telephone may be communicated either to the director or to a person at the office of the director who the person giving the notice has reason to believe will promptly communicate it to the director. The notice need not specify the purpose or the place of the meeting, if the meeting is to be held at the principal executive office of the corporation.

3.10 QUORUM

    A majority of the authorized number of directors shall constitute a quorum for the transaction of business, except to adjourn as provided in Section 3.12 of these Amended and Restated Bylaws. Every act or decision done or made by a majority of the directors present at a duly held meeting at which a quorum is present shall be regarded as the act of the board of directors, subject to the provisions of the certificate of incorporation and applicable law. A meeting at which a quorum is initially present may continue to transact business notwithstanding the withdrawal of directors, if any action taken is approved by at least a majority of the quorum for that meeting.

3.11 WAIVER OF NOTICE

    Notice of a meeting need not be given to any director (i) who signs a waiver of notice, whether before or after the meeting, or (ii) who attends the meeting other than for the express purposed of objecting at the beginning of the meeting to the transaction of any business because the meeting is not lawfully called or convened. All such waivers shall be filed with the corporate records or made part of the minutes of the meeting. A waiver of notice need not specify the purpose of any regular or special meeting of the board of directors.

3.12 ADJOURNMENT

    A majority of the directors present, whether or not constituting a quorum, may adjourn any meeting of the board to another time and place.

9


3.13 NOTICE OF ADJOURNMENT

    Notice of the time and place of holding an adjourned meeting of the board need not be given unless the meeting is adjourned for more than twenty-four (24) hours. If the meeting is adjourned for more than twenty-four (24) hours, then notice of the time and place of the adjourned meeting shall be given before the adjourned meeting takes place, in the manner specified in Section 3.9 of these Amended and Restated Bylaws, to the directors who were not present at the time of the adjournment.

3.14 BOARD ACTION BY WRITTEN CONSENT WITHOUT A MEETING

    Any action required or permitted to be taken by the board of directors may be taken without a meeting, provided that all members of the board individually or collectively consent in writing to that action. Such action by written consent shall have the same force and effect as a unanimous vote of the board of directors. Such written consent and any counterparts thereof shall be filed with the minutes of the proceedings of the board of directors.

3.15 FEES AND COMPENSATION OF DIRECTORS

    Directors and members of committees may receive such compensation, if any, for their services and such reimbursement of expenses as may be fixed or determined by resolution of the board of directors. This Section 3.15 shall not be construed to preclude any director from serving the corporation in any other capacity as an officer, agent, employee or otherwise and receiving compensation for those services.

3.16 APPROVAL OF LOANS TO OFFICERS

GENERAL MATTERS

8.1 RECORD DATE FOR PURPOSES OTHER THAN NOTICE AND VOTING

    For purposes of determining the stockholders entitled to receive payment of any dividend or other distribution or allotment of any rights or the stockholders entitled to exercise any rights in respect of any change, conversion or exchange of stock, or for the purpose of any other lawful action, the board of directors may fix, in advance, a record date, which shall not precede the date upon which the resolution fixing the record date is adopted and which shall not be more than sixty (60) days before any such action. In that case, only stockholders of record at the close of business on the date so fixed are entitled to receive the dividend, distribution or allotment of rights, or to exercise such rights, as the case may be, notwithstanding any transfer of any shares on the books of the corporation after the record date so fixed, except as otherwise provided by law. If the board of directors does not so fix a record date, then the record date for determining stockholders for any such purpose shall be at the close of business on the day on which the board of directors adopts the applicable resolution.

8.2 CHECKS; DRAFTS; EVIDENCES OF INDEBTEDNESS

    From time to time, the board of directors shall determine by resolution which person or persons may sign or endorse all checks, drafts, other orders for payment of money, notes or other evidences of indebtedness that are issued in the name of or payable to the corporation, and only the persons so authorized shall sign or endorse those instruments.

8.3 CORPORATE CONTRACTS AND INSTRUMENTS: HOW EXECUTED

    The board of directors, except as otherwise provided in these Amended and Restated Bylaws, may authorize and empower any officer or officers, or agent or agents, to enter into any contract or execute any instrument in the name of and on behalf of the corporation; such power and authority may be

16


general or confined to specific instances. Unless so authorized or ratified by the board of directors or within the agency power of an officer, no officer, agent or employee shall have any power or authority to bind the corporation by any contract or engagement or to pledge its credit or to render it liable for any purpose or for any amount.

8.4 STOCK CERTIFICATES; TRANSFER; PARTLY PAID SHARES

    The shares of the corporation shall be represented by certificates, provided that the board of directors of the corporation may provide by resolution or resolutions that some or all of any or all classes or series of its stock shall be uncertificated shares. Any such resolution shall not apply to shares represented by a certificate until such certificate is surrendered to the corporation. Notwithstanding the adoption of such a resolution by the board of directors, every holder of stock represented by certificates and, upon request, every holder of uncertificated shares, shall be entitled to have a certificate signed by, or in the name of the corporation by, the chairman or vice-chairman of the board of directors, or the chief executive officer, the president or vice-president, and by the treasurer or an assistant treasurer, or the secretary or an assistant secretary of such corporation representing the number of shares registered in certificate form. Any or all of the signatures on the certificate may be a facsimile. In case any officer, transfer agent or registrar who has signed or whose facsimile signature has been placed upon a certificate has ceased to be such officer, transfer agent or registrar before such certificate is issued, it may be issued by the corporation with the same effect as if he or she were such officer, transfer agent or registrar at the date of issue.

    Certificates for shares shall be of such form and device as the board of directors may designate and shall state the name of the record holder of the shares represented thereby; its number; date of issuance; the number of shares for which it is issued; a summary statement or reference to the powers, designations, preferences or other special rights of such stock and the qualifications, limitations or restrictions of such preferences and/or rights, if any; a statement or summary of liens, if any; a conspicuous notice of restrictions upon transfer or registration of transfer, if any; a statement as to any applicable voting trust agreement; if the shares be assessable, or, if assessments are collectible by personal action, a plain statement of such facts.

    Upon surrender to the secretary or transfer agent of the corporation of a certificate for shares duly endorsed or accompanied by proper evidence of succession, assignment or authority to transfer, it shall be the duty of the corporation to issue a new certificate to the person entitled thereto, cancel the old certificate and record the transaction upon its books.

    The corporation may issue the whole or any part of its shares as partly paid and subject to call for the remainder of the consideration to be paid therefor. Upon the face or back of each stock certificate issued to represent any such partly paid shares, or upon the books and records of the corporation in the case of uncertificated partly paid shares, the total amount of the consideration to be paid therefor and the amount paid thereon shall be stated. Upon the declaration of any dividend on fully paid shares, the corporation shall declare a dividend upon partly paid shares of the same class, but only upon the basis of the percentage of the consideration actually paid thereon.

8.5 SPECIAL DESIGNATION ON CERTIFICATES

    If the corporation is authorized to issue more than one class of stock or more than one series of any class, then the powers, the designations, the preferences and the relative, participating, optional or other special rights of each class of stock or series thereof and the qualifications, limitations or restrictions of such preferences and/or rights shall be set forth in full or summarized on the face or back of the certificate that the corporation shall issue to represent such class or series of stock; provided, how ever, that, except as otherwise provided in Section 202 of the General Corporation Law of Delaware, in lieu of the foregoing requirements there may be set forth on the face or back of the certificate that the corporation shall issue to represent such class or series of stock a statement that the

17


corporation will furnish without charge to each stockholder who so requests the powers, the designations, the preferences and the relative, participating, optional or other special rights of each class of stock or series thereof and the qualifications, limitations or restrictions of such preferences and/or rights.

8.6 LOST CERTIFICATES

    Except as provided in this Section 8.6, no new certificates for shares shall be issued to replace a previously issued certificate unless the latter is surrendered to the corporation and cancelled at the same time. The board of directors may, in case any share certificate or certificate for any other security is lost, stolen or destroyed, authorize the issuance of replacement certificates on such terms and conditions as the board may require; the board may require indemnification of the corporation secured by a bond or other adequate security sufficient to protect the corporation against any claim that may be made against it, including any expense or liability, on account of the alleged loss, theft or destruction of the certificate or the issuance of the replacement certificate.

8.7 TRANSFER AGENTS AND REGISTRARS

    The board of directors may appoint one or more transfer agents or transfer clerks, and one or more registrars, each of which shall be an incorporated bank or trust company—either domestic or foreign, who shall be appointed at such times and places as the requirements of the corporation may necessitate and the board of directors may designate.

8.8 CONSTRUCTION; DEFINITIONS

    Unless the context requires otherwise, the general provisions, rules of construction and definitions in the General Corporation Law of Delaware shall govern the construction of these Amended and Restated Bylaws. Without limiting the generality of this provision, as used in these Amended and Restated Bylaws, the singular number includes the plural, the plural number includes the singular, and the term "person" includes both an entity and a natural person.

ARTICLE IX
AMENDMENTS

    The original or other Amended and Restated Bylaws of the corporation may be adopted, amended or repealed by the stockholders entitled to vote or by the board of directors of the corporation. The fact that such power has been so conferred upon the directors shall not divest the stockholders of the power, nor limit their power to adopt, amend or repeal Amended and Restated Bylaws.

    Whenever an amendment or new bylaw is adopted, it shall be copied in the book of Amended and Restated Bylaws with the original Amended and Restated Bylaws, in the appropriate place. If any bylaw is repealed, the fact of repeal with the date of the meeting at which the repeal was enacted or the filing of the operative written consent(s) shall be stated in said book.

           (i) No person shall have any discretion to select which Outside Directors shall be granted Options or to determine the number of Shares to be covered by Options granted to Outside Directors except as expressly provided by the Plan.

          (ii) Each New Outside Director shall be automatically granted an Option to purchase that number of Shares as shall be determined by the Board in its sole discretion (the "First Option") on the date on which such person first becomes an Outside Director, whether through election by the stockholders of the Company or appointment by the Board to fill a vacancy; provided, however, that an Inside Director who ceases to be an Inside Director but who remains a Director shall not receive a First Option. If the Board does not establish the number of Shares subject to the First Option for a given New Outside Director prior to the date of grant for such First Option, then the number shall be the same as the number of Shares granted to the immediately preceding New Outside Director.

          (iii) Commencing with the fiscal year beginning January 1, 2002, each Outside Director shall be automatically granted an Option to purchase that number of Shares as shall be determined by the Board in its sole discretion (a "Subsequent Option") on the date of the Company's Annual Meeting of Stockholders upon such Outside Director's reelection, if on such date, he or she shall have served on the Board for at least six (6) months. If the Board does not establish the number of Shares subject to the Subsequent Option for a given fiscal year, then the number shall be the same as the number of Shares subject to the Subsequent Option for the immediately preceding fiscal year (as adjusted pursuant to Section 10).

          (iv) Notwithstanding the provisions of subsections (ii) and (iii) hereof, any exercise of an Option granted before the Company has obtained stockholder approval of the Shares to be

2


      issued upon the exercise of such Option shall be conditioned upon obtaining such stockholder approval.

          (v) The terms of a First Option granted hereunder shall be as follows:

            (A) the maximum term of a First Option shall be ten (10) years.

            (B) the First Option shall be exercisable only while the Outside Director remains a Director of the Company, except as set forth in Sections 8 and 10 hereof.

            (C) the exercise price per Share shall be 100% of the Fair Market Value per Share on the date of grant of the First Option. In the event that the date of grant of the First Option is not a trading day, the exercise price per Share shall be the Fair Market Value on the next trading day immediately following the date of grant of the First Option.

            (D) subject to Section 10 hereof, the First Option shall be exercisable immediately, in whole or in part.

          (vi) The terms of a Subsequent Option granted hereunder shall be as follows:

            (A) the maximum term of the Subsequent Option shall be ten (10) years.

            (B) the Subsequent Option shall be exercisable only while the Outside Director remains a Director of the Company, except as set forth in Sections 8 and 10 hereof.

            (C) the exercise price per Share shall be 100% of the Fair Market Value per Share on the date of grant of the Subsequent Option. In the event that the date of grant of the Subsequent Option is not a trading day, the exercise price per Share shall be the Fair Market Value on the next trading day immediately following the date of grant of the Subsequent Option.

            (D) subject to Section 10 hereof, the Subsequent Option shall be exercisable immediately, in whole or in part.

          (vii) In the event that any Option granted under the Plan would cause the number of shares subject to outstanding Options plus the number of Shares previously purchased under Options to exceed the Pool, then the remaining Shares available for Options grant shall be granted under Options to the Outside Directors on a pro rata basis. No further grants shall be made until such time, if any, as additional Shares become available for grant under the Plan through action of the Board or the stockholders to increase the number of Shares which may be issued under the Plan or through cancellation or expiration of Options previously granted hereunder.

    5.  Eligibility.  Options may be granted only to Outside Directors. All Options shall be automatically granted in accordance with the terms set forth in Section 4 hereof.

    The Plan shall not confer upon any Optionee any right with respect to continuation of service as a Director or nomination to serve as a Director, nor shall it interfere in any way with any rights which the Director or the Company may have to terminate the Director's relationship with the Company at any time.

    6.  Term of Plan.  The Plan shall become effective upon the earlier to occur of its adoption by the Board or its approval by the stockholders of the Company as described in Section 16 of the Plan. It shall continue in effect for a term of ten (10) years ending in 2008 unless sooner terminated under Section 11 of the Plan.

    7.  Form of Consideration.  The consideration to be paid for the Shares to be issued upon exercise of an Option, including the method of payment, shall consist of (i) cash, (ii) check, (iii) other shares

3


which (x) in the case of Shares acquired upon exercise of an Option, have been owned by the Optionee for more than six (6) months on the date of surrender, and (y) have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which said Option shall be exercised, (iv) delivery of a properly executed notice together with such other documentation as the Company and the broker, if applicable, shall require to effect an exercise of the Option and delivery to the Company of the sale or loan proceeds required to pay the exercise price, or (v) any combination of the foregoing methods of payment.

    8.  Exercise of Option.  

        (a)  Procedure for Exercise, Rights as a Stockholder.  Any Option granted hereunder shall be exercisable at such times as are set forth in Section 4 hereof and in accordance with the schedule set forth in the agreement documenting an individual Option.

        An Option may not be exercised for a fraction of a Share.

        An Option shall be deemed to be exercised when written notice of such exercise has been given to the Company in accordance with the terms of the Option by the person entitled to exercise the Option and full payment for the Shares with respect to which the Option is exercised has been received by the Company. Full payment may consist of any consideration and method of payment allowable under Section 7 of the Plan. Until the issuance (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company) of the stock certificate evidencing such Shares, no right to vote or receive dividends or any other rights as a stockholder shall exist with respect to the Optioned Stock, notwithstanding the exercise of the Option. A share certificate for the number of Shares so acquired shall be issued to the Optionee as soon as practicable after exercise of the Option. No adjustment shall be made for a dividend or other right for which the record date is prior to the date the stock certificate is issued, except as provided in Section 10 of the Plan.

        Exercise of an Option in any manner shall result in a decrease in the number of Shares which thereafter may be available, both for purposes of the Plan and for sale under the Option, by the number of Shares as to which the Option is exercised.

        (b)  Termination of Continuous Status as a Director.  Subject to Section 10 hereof, in the event an Optionee's status as a Director terminates (other than upon the Optionee's death or disability), the Optionee may exercise his or her Option, but only within ninety (90) days following the date of such termination, and only to the extent that the Optionee was entitled to exercise it on the date of such termination (but in no event later than the expiration of its ten (10) year term); provided, however, that in the event that a sale of the Option Stock received upon exercise of this Option would subject the Director to liability under Section 16(b) of the Securities and Exchange Act of 1934, as amended, then the option will terminate on the earlier of (i) fifteenth day after the last date upon which such sale would result in liability, or (ii) two hundred ten (210) days following the date of such termination of status as a Director (but in no event later than the expiration of its ten (10) year term). To the extent that the Optionee was not entitled to exercise an Option on the date of such termination, and to the extent that the Optionee does not exercise such Option (to the extent otherwise so entitled) within the time specified herein, the Option shall terminate.

        (c)  Disability of Optionee.  In the event Optionee's status as a Director terminates as a result of disability, the Optionee may exercise his or her Option, but only within twelve (12) months following the date of such termination, and only to the extent that the Optionee was entitled to exercise it on the date of such termination (but in no event later than the expiration of its ten (10) year term). To the extent that the Optionee was not entitled to exercise an Option on the date of the time specified herein, the Option shall terminate.

4


        (d)  Death of Optionee.  In the event of an Optionee's death, the Optionee's estate or a person who acquired the right to exercise the Option by bequest or inheritance may exercise the Option, but only within twelve (12) months following the date of death, and only to the extent that the Optionee was entitled to exercise it on the date of death (but in no event later than the expiration of its ten (10) year term). To the extent that the Optionee was not entitled to exercise an Option on the date of death, and to the extent that the Optionee's estate or a person who acquired the right to exercise such Option does not exercise such Option (to the extent otherwise so entitled) within the time specified herein, the Option shall terminate.

    9.  Non-Tranferability of Options.  The Option may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised, during the lifetime of the Optionee, only by the Optionee.

    10.  Adjustments Upon Changes in Capitalization, Dissolution, Merger or Asset Sale.  

        (a)  Changes in Capitalization.  Subject to any required action by the stockholders of the Company, the number of Shares covered by each outstanding Option, the number of Shares which have been authorized for issuance under the Plan but as to which no Options have yet been granted or which have been returned to the Plan upon cancellation or expiration of an Option, as well as the price per Share covered by each such outstanding Option, and the number of Shares issuable pursuant to the grant provisions of Section 4 hereof shall be proportionately adjusted for any increase or decrease in the number of issued Shares resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of the Common Stock, or any other increase or decrease in the number of issued Shares effected without receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the Company shall not be deemed to have been "effected without receipt of consideration." Except as expressly provided herein, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of Shares subject to an Option.

        (b)  Dissolution or Liquidation.  In the event of the proposed dissolution or liquidation of the Company, to the extent that an Option has not been previously exercised, it shall terminate immediately prior to the consummation of such proposed action.

        (c)  Merger or Asset Sale.  In the event of a merger or consolidation of the Company with or into another corporation or the sale of substantially all of the assets of the Company, outstanding Options may be assumed or equivalent options may be substituted by the successor corporation or a Parent or Subsidiary thereof (the "Successor Corporation"). If an Option is assumed or substituted for, the Option or equivalent option shall continue to be exercisable as provided in Section 4 hereof for so long as the Optionee serves as a Director or a director of the Successor Corporation. Following such assumption or substitution, if the Optionee's status as a Director or director of the Successor Corporation, as applicable, is terminated other than upon a voluntary resignation by the Optionee, the Option or option shall become fully exercisable, including as to Shares for which it would not otherwise be exercisable. Thereafter, the Option or option shall remain exercisable in accordance with Sections 8(b) through (d) above.

        If the Successor Corporation does not assume an outstanding Option or substitute for it an equivalent option, the Option shall become fully vested and exercisable, including as to Shares for which it would not otherwise be exercisable. In such event the Board shall notify the Optionee that the Option shall be fully exercisable for a period of thirty (30) days from the date of such notice, and upon the expiration of such period the Option shall terminate.

        For purposes of this Section 10(c), an Option shall be considered assumed if, following the merger, consolidation or sale of assets, the Option confers the right to purchase or receive, for

5


    each Share of Optioned Stock subject to the Option immediately prior to the merger, consolidation or sale of assets, the consideration (whether stock, cash, or other securities or property) received in the merger, consolidation or sale of assets by holders of Common Stock for each Share held on the effective date of the transaction (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding Shares). If such consideration received in the merger, consolidation or sale of assets is not solely common stock of the successor corporation or its Parent, the Administrator may, with the consent of the successor corporation, provide for the consideration to be received upon the exercise of the Option, for each Share of Optioned Stock subject to the Option, to be solely common stock of the successor corporation or its Parent equal in fair market value to the per share consideration received by holders of Common Stock in the merger, consolidation or sale of assets.

    11.  Amendment and Termination of the Plan.  

        (a)  Amendment and Termination.  Except as set forth in Section 4, the Board may at any time amend, alter, suspend, or discontinue the Plan, but no amendment, alteration, suspension or discontinuation shall be made which would impair the rights of any Optionee under any grant theretofore made, without his or her consent. In addition, to the extent necessary and desirable to comply with any applicable law or regulation, the Company shall obtain stockholder approval of any Plan amendment in such manner and to such a degree as required.

        (b)  Effect of Amendment or Termination.  Any such amendment or termination of the Plan shall not affect Options already granted and such Options shall remain in full force and effect as if this Plan had not been amended or terminated.

    12.  Time of Granting Options.  The date of grant of an Option shall, for all purposes, be the date determined in accordance with Section 4 hereof.

    13.  Conditions Upon Issuance of Shares.  Shares shall not be issued pursuant to the exercise of an Option unless the exercise of such Option and the issuance and delivery of such Shares pursuant thereto shall comply with all relevant provisions of law, including, without limitation, the Securities Act of 1933, as amended, the Exchange Act, the rules and regulations promulgated thereunder, state securities laws, and the requirements of any stock exchange upon which the Shares may then be listed, and shall be further subject to the approval of counsel for the Company with respect to such compliance.

    As a condition to the exercise of an Option, the Company may require the person exercising such Option to represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares, if, in the opinion of counsel for the Company, such representation is required by any of the aforementioned relevant provisions of law.

    Inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company's counsel to be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority shall not have been obtained.

    14.  Reservation of Shares.  The Company, during the term of this Plan, will at all times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan.

    15.  Option Agreement.  Options shall be evidenced by written option agreements in such form as the Board shall approve.
