Dynavax Technologies Corporation
Notes to Condensed Consolidated Financial Statements
(Unaudited)
1. Organization
     Dynavax Technologies Corporation (“Dynavax”, the “Company”, “we” or “us”) is a biopharmaceutical company that discovers, develops, and intends to commercialize innovative products to treat and prevent allergies, infectious diseases, and chronic inflammatory diseases. The Company was originally incorporated in California on August 29, 1996 and reincorporated in Delaware on March 26, 2001.
     In February 2004, the Company sold a total of 6,900,000 shares of its common stock, after adjusting for a one-for-three reverse stock split, in an underwritten initial public offering, raising net proceeds of approximately $46.5 million. The effect of the reverse stock split is reflected in the Condensed Consolidated Financial Statements for all periods presented.
Subsidiaries
     In October 2003, the Company formed Dynavax Asia Pte. Ltd. (Dynavax Asia), a 100% owned subsidiary in Singapore which focuses on the Company’s clinical and preclinical hepatitis B programs. In December 2004, the Company formed Ryden Therapeutics KK (Ryden), a 100% owned Japan subsidiary, to explore development and commercialization options for ISS-based immunotherapies for cedar tree allergy in Japan.
2. Summary of Significant Accounting Policies
Basis of Presentation
     Our accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles for interim financial information and pursuant to the instructions to Form 10-Q and Article 10 of Regulation S-X. In our opinion, these unaudited Condensed Consolidated Financial Statements include all adjustments, consisting only of normal recurring adjustments, which we consider necessary to fairly state our financial position and the results of our operations and cash flows. Interim-period results are not necessarily indicative of results of operations or cash flows for a full-year period. The balance sheet at December 31, 2004 has been derived from audited financial statements at that date, but does not include all disclosures required by U.S. generally accepted accounting principles for complete financial statements.
     These unaudited Condensed Consolidated Financial Statements and the notes accompanying them should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2004 as filed with the Securities and Exchange Commission (SEC) on March 18, 2005.
     The Condensed Consolidated Financial Statements include the accounts of Dynavax, Dynavax Asia and Ryden. All significant intercompany accounts and transactions have been eliminated. The Company operates in one business segment, which is the development of biopharmaceutical products.
Use of Estimates
     The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the Condensed Consolidated Financial Statements and accompanying notes. Actual results may differ from these estimates.
Critical Accounting Policies
     The Company believes that there have been no significant changes in its critical accounting policies during the six months ended June 30, 2005 as compared with those disclosed in its Annual Report on Form 10-K for the year ended December 31, 2004.

Recent Accounting Pronouncements On March 29, 2005, the SEC published Staff Accounting Bulletin (SAB) No. 107 regarding the interaction between Financial Accounting Standard (FAS) No. 123R (revised 2004), “Share-Based Payment” and certain SEC rules and regulations. The Financial Accounting Standards Board (FASB) issued FAS No. 123R on December 16, 2004, that requires all share-based payments to employees, including grants of employee stock options, to be recognized based on their fair values. Pro forma disclosure is no longer an alternative. FAS No. 123R supersedes Accounting Principles Board (APB) No. 25, “Accounting for Stock Issued to Employees,” and amends FAS No. 95, “Statement of Cash Flows.”
     Under FAS No. 123R, share-based payments result in a cost that will be measured at fair value on the awards’ grant date, based on the estimated number of awards that are expected to vest. Compensation cost for awards that vest would not be reversed if the awards expire without being exercised. When measuring fair value, companies can choose an option-pricing model (e.g., Black-Scholes or binomial models) that appropriately reflects their specific circumstances and the economics of their transactions. Public companies are allowed to select from alternative transition methods, each having different reporting implications. FAS No. 123R is effective for the fiscal year beginning after June 15, 2005, and applies to all outstanding and unvested share-based payments as of the adoption date.
     We will adopt FAS No. 123R as of January 1, 2006. The adoption of FAS No. 123R’s fair value method will have a significant impact on our result of operations, although it will have no impact on our overall financial position. The impact of adoption of FAS No. 123R cannot be predicted at this time because we are in the process of reevaluating our methodology used to determine fair value, including consideration of an option-pricing model and related assumptions. In addition, the impact of adoption will depend on levels of share-based payments granted in the future.
Stock-Based Compensation
     As permitted under FAS No. 123, “Accounting for Stock-Based Compensation” as amended by FAS No. 148, “Accounting for Stock-Based Compensation — Transition and Disclosure,” we continue to recognize employee stock compensation under the intrinsic value method of accounting as prescribed by APB No. 25 and its interpretations. Under APB No. 25, compensation expense is based on the difference, if any, between the estimated fair value of our common stock and the option exercise price on the date of grant. We account for stock compensation to non-employees in accordance with FAS No. 123, as amended by FAS No. 148 and EITF Issue 96-18, “Accounting for Equity Instruments That Are Issued to Other Than Employees for Acquiring, or in Conjunction with Selling Goods or Services.”
     The following table illustrates the pro forma effect on our net loss and net loss per share as if we had applied the fair value recognition provisions of FAS No. 123 to employee stock compensation (in thousands, except per share amounts):
                                 
    Three Months Ended     Six Months Ended

Net loss per share:
                               
Basic and diluted net loss, as reported
  $ (0.35 )   $ (0.12 )   $ (0.14 )   $ (0.38 )
 
                       
Basic and diluted net loss, pro forma
  $ (0.36 )   $ (0.12 )   $ (0.17 )   $ (0.40 )
 
                       
     Such pro forma disclosure may not be representative of future stock-based compensation expense because such options vest over several years and additional grants may be made each year.

3. Commitments and Contingencies
     The Company leases its facility under an operating lease that expires in September 2014. The lease can be terminated at no cost to the Company in September 2009 but otherwise extends automatically until September 2014.
     Our facility lease agreement provides for periods of escalating rent. The total cash payments over the life of the lease were divided by the total number of months in the lease period and the average rent is charged to expense each month during the lease period. In addition, our lease agreement provides a tenant improvement allowance of $0.4 million, which is considered a lease incentive and accordingly, has been included in accrued liabilities and other long-term liabilities in the Condensed Consolidated Balance Sheets as of June 30, 2005 and December 31, 2004. The lease incentive is amortized as an offset to rent expense over the estimated initial lease term, through September 2009. Total net rent expense related to this operating lease for the six months ended June 30, 2005 was $0.7 million. Deferred rent was $0.1 million as of June 30, 2005.
     We have entered into a sublease agreement for a certain portion of the leased space with scheduled payments to the Company of $339,990 annually through 2007. This sublease agreement includes an option for early termination in August 2006 but otherwise extends automatically until August 2007.
     Future minimum payments under the non-cancelable portion of our operating lease at June 30, 2005, excluding payments from the sublease agreement, are as follows (in thousands):
         
Year ending December 31,        
2005
  $ 1,246  
2006
    1,704  
2007
    1,755  
2008
    1,807  
2009
    1,231  
 
     
 
  $ 7,743  
 
     
     During the fourth quarter of 2004, we established a letter of credit with Silicon Valley Bank as security for our property lease in the amount of $0.4 million. The letter of credit remained outstanding as of June 30, 2005 and is collateralized by a certificate of deposit which has been included in restricted cash in the Condensed Consolidated Balance Sheets as of June 30, 2005 and December 31, 2004. Under the terms of the lease agreement, if the total amount of our cash, cash equivalents and marketable securities falls below $20.0 million for a period of more than 30 consecutive days during the lease term, the amount of the required security deposit will increase to $1.1 million, until such time as our projected cash and cash equivalents will exceed $20.0 million for the remainder of the lease term, or until our actual cash and cash equivalents remains above $20.0 million for a period of 12 consecutive months.
     We rely on research institutions and contract research organizations that conduct and manage clinical trials on our behalf. As of June 30, 2005, under the terms of our agreements with a contract research organization (CRO) and clinical investigator, we are obligated to make future payments as services are provided of up to $13.4 million through 2008. This agreement is terminable by us upon written notice to the CRO and we are only liable for actual effort expended by the CRO at any point in time during the contract.
     The Company, as permitted under Delaware law and in accordance with its bylaws, indemnifies its officers and directors for certain events or occurrences, subject to certain limits, while the officers or directors are or were serving at the Company’s request in such capacity. The term of the indemnification period is for each officer or director’s lifetime. The maximum amount of potential future indemnification is unlimited; however, the Company has a director and officer insurance policy that limits its exposure up to

Table of Contents

     $10.0 million and may enable the Company to recover a portion of any future amounts paid. The Company believes the estimated fair value of these indemnification agreements is minimal. Accordingly, the Company has no liabilities recorded for these agreements as of June 30, 2005.
     The Company enters into indemnification provisions under its agreements with other companies in its ordinary course of business, typically with business partners, contractors, clinical sites and customers. Under these provisions, the Company generally indemnifies and holds harmless the indemnified party for losses suffered or incurred by the indemnified party as a result of the Company’s activities. These indemnification provisions generally survive termination of the underlying agreement. The maximum potential amount of future payments the Company could be required to make under these indemnification provisions is unlimited. The Company has not incurred material costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, the estimated fair value of these agreements is minimal. Accordingly, the Company has no liabilities recorded for these agreements as of June 30, 2005.
4. Collaborative Research, Development, and License Agreements
UCB Farchim, S.A.
     In March 2005, the Company agreed to end its collaboration with UCB Farchim, S.A. (UCB) and regained full rights to its allergy program. During the quarter ended June 30, 2005, the Company received cash payments in satisfaction of outstanding receivables due from UCB and obligations owed by UCB under the collaboration. During the six months ended June 30, 2005, the Company accelerated the recognition of $7.0 million in deferred revenue related to the collaboration, as the Company had no ongoing obligations under the collaboration, and also recognized revenue associated with cash received following the ending of the collaboration.
University of California
     The Company entered into a series of exclusive license agreements with the Regents of the University of California (UC) in March 1997 and October 1998. These agreements provide the Company with certain technology and related patent rights and materials. Under the terms of the agreements, the Company pays annual license or maintenance fees and will be required to pay milestones and royalties on net sales of products originating from the licensed technologies. The agreements will expire on either the expiration date of the last-to-expire patent licensed under the agreements or the date upon which the last patent application licensed under the agreements is abandoned.
     In connection with these license agreements, the Company incurred license fees of $20,000 during the first six months of 2005 and 2004 which was recorded as research and development expense, and the Company incurred patent expenses of $0.2 million and $0.1 million during the six months ended June 30, 2005 and 2004, respectively, which was recorded as general and administrative expense. As partial consideration for the technology licenses, the Company also incurred a $0.4 million one-time charge due upon the closing of the Company’s initial public offering in the first quarter of 2004, which was recorded as research and development expense. Additionally, as partial consideration for the technology licenses, the Company paid $0.2 million to UC related to the collaboration with UCB. During the six months ended June 30, 2005, in conjunction with the ending of the UCB collaboration, the Company incurred $0.1 million in research and development expense from the accelerated amortization of the prepaid technology licenses fee.
BioSeek, Inc.
     In June 2003, the Company entered into a development collaboration agreement with BioSeek, Inc. to analyze and characterize the activity of certain compounds using BioSeek’s technology with the objective of advancing the development of such compounds. Under this agreement, the Company will make various payments to BioSeek based on the success and timing of the Company’s signing of a third party partnering agreement where the Company grants to the third party, directly or indirectly, any right or option to market, sell, distribute or otherwise commercialize a thiazolopyrimidine (TZP) product in any geographic territory. The agreement may be terminated by either party. During the six months ended June 30, 2005, we paid BioSeek $0.3 million associated with the achievement of a contractual milestone.
Other Agreements
     In the third quarter of 2003, the Company was awarded government grants totaling $8.4 million to be received over as long as three and one-half years, assuming annual review criteria are met, to fund research and development of certain biodefense programs.

Revenue associated with these grants is recognized as the related expenses are incurred. During the second quarter of 2005, the indirect cost rate associated with these grants was approved by the National Institutes of Health. As a result, the grant revenue for the quarter ended June 30, 2005 of approximately $1.0 million included a one-time increase of $0.5 million, reflecting the adjustment under the government grant awards from the previously utilized minimum cost overhead rate allowable to the final approved rate.
     In the fourth quarter of 2004, the Company was awarded $0.5 million from the Alliance for Lupus Research to be received during 2005 and 2006 to fund research and development of new treatment approaches for lupus. For the six months ended June 30, 2005, we recognized revenue of approximately $0.1 million associated with the lupus grant.
5. Net Income (Loss) Per Share
     Basic net income (loss) per share is calculated by dividing net income (loss) for the period by the weighted-average shares outstanding for that period. Diluted net income (loss) per share takes into account the effect of diluted instruments, such as stock options and warrants, and uses the average share price for the period in determining the number of incremental shares that are to be added to the weighted-average number of shares outstanding.

    24,745,456       24,593,881       24,733,707       17,720,420  
     Certain potentially dilutive shares were excluded from the shares used to compute diluted net income (loss) per share since their inclusion would have been anti-dilutive, either because the options’ exercise prices exceeded the average fair market value of the stock during the period or due to the loss for the period.
6. Stockholders’ Equity
     At June 30, 2005, there were 24,747,817 shares of our common stock issued and outstanding.

     In April 2005, in accordance with the terms of the 2004 Employee Stock Purchase Plan (the “Purchase Plan”), the Board of Directors approved an increase of 246,000 shares of common stock available for purchase. During the six months ended June 30, 2005, employees acquired 12,374 shares of our common stock. At June 30, 2005, 470,929 shares of our common stock remained available for future purchases under the Purchase Plan.
     Also in April 2005, the Company adopted a compensation plan for its Board of Directors in the form of revisions to its 2004 Non-employee Director Option Program and 2004 Director Cash Compensation Program. The plan generally provides that each director, other than the chair of the board, receive an option to purchase 20,000 shares of common stock on April 14, 2005, subsequent annual grants at the stockholders’ meeting (beginning with the 2006 meeting) of 10,000 shares each year thereafter, a $20,000 annual retainer, and $2,000 for each in-person board meeting or $500 for each telephonic board meeting attended. The plan also provides that the chair of the board receive an option to purchase 30,000 shares of common stock on April 14, 2005, subsequent annual grants at the stockholders’ meeting (beginning with the 2006 meeting) of 10,000 shares each year thereafter, a $30,000 annual retainer, and $2,000 for each in-person board meeting or $500 for each telephonic board meeting attended. In addition, the plan provides that the chair of the Audit Committee, Compensation Committee and Nominating Committee receive an annual retainer of $15,000, $6,000 and $3,000, respectively. Directors attending meetings of the Audit Committee will receive $1,500 per in-person meeting or $500 per telephonic meeting. Directors attending meetings of the Compensation and Nominating Committees will receive $1,000 per in-person meeting or $500 per telephonic meeting.
     Certain of the Company’s directors and their affiliates beneficially owned or controlled approximately 17% of our outstanding common stock as of June 30, 2005. For the three and six months ended June 30, 2005, the Company incurred approximately $41,000 in general and administrative expense associated with payments to these directors under the compensation plan.
7. Related Party Transactions
     From September 2000 through June 2001, the Company loaned $0.8 million to certain key employees and officers for the exercise of incentive stock options. These are full recourse notes, which accrue interest at rates ranging from 5.02% to 6.22% and are due through November 2005. The shares of common stock held by the employees collateralize these notes. During the six months ended June 30, 2005, approximately $0.1 million was repaid to the Company. As of June 30, 2005, the remaining balance of the notes receivable from shareholders was $0.3 million.

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 under federal securities laws. Forward-looking statements are not guarantees of future performance and involve a number of risks and uncertainties. Our actual results could differ materially from those indicated by forward-looking statements as a result of various factors, including but not limited to those set forth under this Item, as well as those discussed elsewhere in this document and those that may be identified from time to time in our reports and registration statements filed with the Securities and Exchange Commission.
     This discussion should be read in conjunction with the Condensed Consolidated Financial Statements and related Notes included in Item 1 of this quarterly report and the Consolidated Financial Statements and related Notes and Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in our Annual Report on Form 10-K as filed with the Securities and Exchange Commission on March 18, 2005.
Overview
     We discover, develop, and intend to commercialize innovative products to treat and prevent allergies, infectious diseases, and chronic inflammatory diseases using versatile, proprietary approaches that alter immune system responses in highly specific ways. Our clinical development programs are based on immunostimulatory sequences, or ISS, which are short DNA sequences that we believe enhance the ability of the immune system to fight disease and control chronic inflammation. The most advanced clinical programs in Dynavax’s ISS-based pipeline are a ragweed allergy immunotherapeutic and a hepatitis B vaccine.
     We have developed a novel injectable product candidate to treat ragweed allergy that we call AIC (for Amb a1 ISS Conjugate). AIC has completed Phase II trials, and is currently completing a two-year Phase II/III clinical trial. At the end of 2004, we reported that the one-year interim analysis of this Phase II/III trial showed a clear positive trend relative to the trial’s major endpoint of nasal symptom scores, as well as other secondary endpoints, following the 2004 ragweed season. We intend to complete the Phase II/III clinical trial. In 2005, we initiated a clinical trial in ragweed allergic children designed to support our Phase III pivotal program. Pending the outcome of discussions with the U.S. Food and Drug Administration (FDA) and the results of the Phase II/III study, we plan to initiate a pivotal Phase III clinical program in early 2006.
     We have developed a product candidate for hepatitis B prophylaxis. A Phase II/III trial in subjects who are more difficult to immunize with conventional vaccines is currently underway in Singapore. Results from an interim analysis of the Phase II/III trial showed that our vaccine demonstrated statistically significant superiority in protective antibody response and robustness of protective effect after two vaccinations when compared to GlaxoSmithKline’s Engerix-B® vaccine. Results from the primary endpoint analysis of this trial showed statistically significant superiority in protective antibody response and robustness of protective effect after three vaccinations when compared to Engerix-B. Results from a Phase II clinical trial in healthy adults conducted earlier in 2004 showed that our vaccine induced a more robust and durable antibody response than Engerix-B. In June 2005, we initiated a pivotal Phase III trial in the older, more difficult to immunize population in Asia. We anticipate initiating a second pivotal Phase III trial in younger adults in Canada and Europe in early 2006. We believe that strategic opportunities for our vaccine exist in selected countries worldwide. Our initial commercialization strategies will likely target these markets and focus on high-value, underserved populations. These populations include pre-hemodialysis patients, HIV and HCV positive patients, other populations with compromised immune systems as well as professionals in healthcare and law enforcement for whom achieving seroprotection quickly is critical.
     We have an inhaled therapeutic product candidate for treatment of asthma, which has completed a Phase IIa trial in Canada. We are performing additional preclinical work to optimize the route of administration and regimen for the asthma clinical program and have postponed additional clinical trials in asthma.
     For the six months ended June 30, 2005, our net loss was $3.5 million, compared to $6.8 million for the same period in 2004. Our operating results for the first half of 2005 reflect the financial impact resulting from the ending of our development and commercialization collaboration with UCB Farchim, S.A. (UCB) that occurred in March 2005. Total revenues for the six months ended June 30, 2005 were $13.7 million, compared to $8.7 million for the same period in 2004. During the first half of 2005, 89% of our revenues were derived from our collaboration activities with UCB and the ending of our collaboration, while the remaining revenues were earned from government and private agency grants. Our ability to generate future collaboration revenue will be dependent on our ability to enter into new collaborative relationships.

     As of June 30, 2005, we had an accumulated deficit of $98.8 million. We do not have any products that generate revenue. We expect to incur substantial and increasing losses as we continue the development of our lead product candidates and preclinical and research programs. If we were to receive regulatory approval for any of our product candidates, we would be required to invest significant capital to develop, or otherwise secure through collaborative relationships, commercial scale manufacturing, marketing and sales capabilities. Even if we are able to obtain approval for our product candidates, we are likely to incur increased operating losses until product sales grow sufficiently to support the organization.
     For the year ended December 31, 2005, excluding the potential impact of any business collaborations or other transactions that may be entered into, we anticipate that our operating expenses will increase as compared to prior year in connection with our clinical development activities and overall organizational growth.
Critical Accounting Policies and the Use of Estimates
     The Company believes that there have been no significant changes in its critical accounting policies during the six months ended June 30, 2005 as compared with those disclosed in its Annual Report on Form 10-K for the year ended December 31, 2004.

Revenues
     Total revenues of approximately $1.0 million for the three months ended June 30, 2005 declined by $4.5 million compared to the same period in 2004, primarily resulting from the loss of collaboration revenue derived from our agreement with UCB as discussed below. Total revenues of $13.7 million for the six months ended June 30, 2005 increased by $5.0 million compared to the same period in 2004. Revenues for the first six months of 2005 were comprised of $12.2 million from our collaboration activities including ending our collaboration with UCB and $1.5 million from government and private agency grants.
     In March 2005, we agreed to end the collaboration with UCB and regained full rights to our allergy program. During the quarter ended June 30, 2005, we received cash payments in satisfaction of outstanding receivables due from UCB and obligations owed by UCB under the collaboration. During the six months ended June 30, 2005, we accelerated the recognition of $7.0 million in deferred revenue related to the collaboration, as we had no ongoing obligations under the collaboration, and also recognized revenue associated with cash received following the ending of the collaboration. Our ability to generate future collaboration revenue and obtain additional capital will be dependent on our ability to enter into new collaborative relationships.
     During the second quarter of 2005, the indirect cost rate associated with our grants from the National Institutes of Health was approved. As a result, the grant revenue for the quarter ended June 30, 2005 of approximately $1.0 million included a one-time increase of $0.5 million, reflecting the adjustment under the government grant awards from the previously utilized minimum cost overhead rate allowable to the final approved rate.

Research and Development
     Research and development expense consists primarily of outside services related to our preclinical experiments and clinical trials, regulatory filings, manufacturing our product candidates for our preclinical experiments and clinical trials; compensation and related personnel costs which include benefits, recruitment, travel and supply costs; allocated facility costs and non-cash stock-based compensation. We expense our research and development costs as they are incurred.
     The following is a summary of our research and development expense (in thousands):

     Research and development expenses of $7.5 million and $13.1 million for the three and six months ended June 30, 2005 increased by $1.0 million, or 15%, and $1.4 million, or 12%, respectively, from the same periods in 2004. The increase over the prior year was primarily due to increased compensation and related personnel costs attributed to organizational growth. In addition, allocated rent and operating costs for our facility rose from the prior year. Outside costs for research, clinical trial and clinical manufacturing increased for the three months ended June 30, 2005 primarily associated with our ragweed allergy and hepatitis B vaccine programs. However, outside services declined for the six months ended June 30, 2005 due to higher start-up costs for our ragweed allergy program as well as expenses incurred to license technology from the Regents of the University of California in the first quarter 2004.
     During 2005, we anticipate that our research and development expense will increase as compared to prior year, in connection with our growing clinical development programs, including the AIC trial in ragweed allergic children designed to support our Phase III pivotal program and the Phase III clinical trial for our hepatitis B vaccine initiated in mid-2005.
General and Administrative
     General and administrative expense consists primarily of compensation and related personnel costs, outside services such as accounting, consulting, investor relations and insurance, legal and patent costs, allocated facility costs and non-cash stock-based compensation.
     The following is a summary of our general and administrative expense (in thousands):

     General and administrative expenses of $2.5 million and $4.8 million for the three and six months ended June 30, 2005 increased by $0.4 million, or 19%, and $0.8 million, or 20%, respectively, from the same periods in 2004. The increase over the prior year primarily reflects higher compensation and related benefits associated with the expansion of our management team and overall organizational growth. In addition, outside services, including administrative, accounting and consulting fees, increased primarily as a

result of the review and testing of our internal control systems in compliance with the requirements of the Sarbanes-Oxley Act. Legal and patent-related costs during the six months ended June 30, 2005 were net of $0.2 million in reimbursable patent interference costs.
     During 2005, we expect general and administrative expenses to increase as compared to prior year, primarily resulting from the full year impact of organizational growth that occurred in 2004 and expenses incurred to support public company compliance requirements.
Interest Income, Net
     Interest income, net of interest expense and amortization on marketable securities, was $0.4 million and $0.8 million, respectively, for the three and six months ended June 30, 2005 compared to $0.2 million and $0.3 million for the same periods in 2004. The increase was primarily due to the investment of proceeds from our initial public offering in marketable securities in February 2004.
Recent Accounting Pronouncements
     On March 29, 2005, the SEC published Staff Accounting Bulletin (SAB) No. 107 regarding the interaction between Financial Accounting Standard (FAS) No. 123R (revised 2004), “Share-Based Payment” and certain SEC rules and regulations. The Financial Accounting Standards Board (FASB) issued FAS No. 123R on December 16, 2004, that requires all share-based payments to employees, including grants of employee stock options, to be recognized based on their fair values. Pro forma disclosure is no longer an alternative. FAS No. 123R supersedes Accounting Principles Board (APB) No. 25, “Accounting for Stock Issued to Employees,” and amends FAS No. 95, “Statement of Cash Flows.”
     Under FAS No. 123R, share-based payments result in a cost that will be measured at fair value on the awards’ grant date, based on the estimated number of awards that are expected to vest. Compensation cost for awards that vest would not be reversed if the awards expire without being exercised. When measuring fair value, companies can choose an option-pricing model (e.g., Black-Scholes or binomial models) that appropriately reflects their specific circumstances and the economics of their transactions. Public companies are allowed to select from three alternative transition methods, each having different reporting implications. FAS No. 123R is effective for the fiscal year beginning after June 15, 2005, and applies to all outstanding and unvested share-based payments as of the adoption date.
     We will adopt FAS No. 123R as of January 1, 2006. The adoption of FAS No. 123R’s fair value method will have a significant impact on our result of operations, although it will have no impact on our overall financial position. The impact of adoption of FAS No. 123R cannot be predicted at this time because we are in the process of reevaluating our methodology used to determine fair value, including consideration of an option-pricing model and related assumptions. In addition, the impact of adoption will depend on levels of share-based payments granted in the future.
Liquidity and Capital Resources
     We have financed our operations since inception primarily through the sale of shares of our common stock, shares of our convertible preferred stock, and ordinary shares in a subsidiary, which have yielded a total of approximately $144.8 million in net cash proceeds and, to a lesser extent, through amounts received under collaborative agreements and government grants for biodefense programs. We completed an initial public offering in February 2004, raising net proceeds during fiscal 2004 of approximately $46.5 million from the sale of 6,900,000 shares of common stock. As of June 30, 2005, we had $58.2 million in cash, cash equivalents and marketable securities. Our funds are currently invested in a variety of securities, including highly liquid institutional money market funds, commercial paper, government and non-government debt securities and corporate obligations.
     Cash used in operating activities of $6.7 million during the six months ended June 30, 2005 compared to $1.0 million for the same period in 2004. The variance from the prior year was due primarily to the one-time $8.0 million upfront payment made to us by UCB in 2004 and a decline in working capital.
     Cash used in investing activities of $4.9 million during the six months ended June 30, 2005 compared to cash provided by investing activities of $5.1 million for the same period in 2004. The variance from the prior year was due primarily to net purchases of investments.

     Cash provided by financing activities of $0.2 million during the six months ended June 30, 2005 compared to $46.4 million for the same period in 2004. Cash provided by financing activities during the first half of 2004 resulted primarily from the issuance of common stock in our initial public offering.
     Excluding the potential impact of any equity offerings, business collaborations or other transactions that may be entered into, we expect our cash, cash equivalents and marketable securities to decline by December 31, 2005, primarily due to cash used for operations.
     We believe our existing capital resources will be adequate to satisfy our capital needs for at least the next twelve months. Because of the significant time it will take for any of our product candidates to complete the clinical trials process, be approved by regulatory authorities and successfully commercialized, we may require substantial additional capital resources. We may raise additional funds through public or private equity offerings, debt financings, capital lease transactions, corporate collaborations or other means. We may attempt to raise additional capital due to favorable market conditions or strategic considerations even if we have sufficient funds for planned operations.
     Additional financing may not be available on acceptable terms, if at all. Capital may become difficult or impossible to obtain due to poor market or other conditions that are outside of our control. If at any time sufficient capital is not available, either through existing capital resources or through raising additional funds, we may be required to delay, scale back or eliminate some or all of our research or development programs, to lose rights under existing licenses or to relinquish greater or all rights to product candidates at an earlier stage of development or on less favorable terms than we would otherwise choose or may adversely affect our ability to operate as a going concern.
Contractual Obligations
     The following summarizes our significant contractual obligations as of June 30, 2005 and the effect those obligations are expected to have on our liquidity and cash flow in future periods (in thousands):
                                 
    Payments Due by Period  
Contractual Obligations:   Total     Less than 1 Year     1-3 Years     4-5 Years  
Future minimum payments under our operating lease
  $ 7,743     $ 1,246     $ 3,459     $ 3,038  
 
                       
Total
  $ 7,743     $ 1,246     $ 3,459     $ 3,038  
 
                       
     We lease our facility under an operating lease that expires in September 2014. The lease can be terminated at no cost to us in September 2009 but otherwise extends automatically until September 2014. We have entered into a sublease agreement for a certain portion of the leased space with scheduled payments to us of $339,990 annually through 2007. This sublease agreement includes an option for early termination in August 2006 but otherwise extends automatically until August 2007.
     The table above excludes certain commitments that are contingent upon future events. The most significant of these contractual commitments that we consider to be contingent obligations are summarized below.
     During the fourth quarter of 2004, we established a letter of credit with Silicon Valley Bank as security for our property lease in the amount of $0.4 million. The letter of credit remained outstanding as of June 30, 2005 and is collateralized by a certificate of deposit which has been included in restricted cash in the Condensed Consolidated Balance Sheets as of June 30, 2005 and December 31, 2004. Under the terms of the lease agreement, if the total amount of our cash, cash equivalents and marketable securities falls below $20.0 million for a period of more than 30 consecutive days during the lease term, the amount of the required security deposit will increase to $1.1 million, until such time as our projected cash and cash equivalents will exceed $20.0 million for the remainder of the lease term, or until our actual cash and cash equivalents remains above $20.0 million for a period of 12 consecutive months.
     We rely on research institutions and contract research organizations that conduct and manage clinical trials on our behalf. As of June 30, 2005, under the terms of our agreements with a contract research organization (CRO) and clinical investigator, we are obligated to make future payments as services are provided of up to $13.4 million through 2008. This agreement is terminable by us upon written notice to the CRO and we are only liable for actual effort expended by the CRO at any point in time during the contract.
     In March 2005, we agreed to end the collaboration with UCB and regained full rights to our allergy program. We assume financial responsibility for all further clinical, regulatory, manufacturing and commercial activities related to AIC and for preclinical development programs in grass and in peanut allergy. During the quarter ended June 30, 2005, we received cash payments in satisfaction of outstanding receivables due from UCB and obligations owed by UCB under the collaboration. The March 2005

agreement also provides for the continued partial reimbursement of certain patent interference fees and expenses, if and as incurred by the Company, subject to a maximum amount.
     Under the terms of the exclusive license agreements with the Regents of the University of California, we are obligated to pay annual license or maintenance fees and will be required to pay future milestones and royalties on net sales of products originating from the licensed technologies. As partial consideration for the technology licenses, during the first quarter of 2004 we paid one-time charges of $0.4 million upon the closing of the Company’s initial public offering and $0.2 million related to the collaboration with UCB. No other milestones were achieved as of June 30, 2005.
     Under the development collaboration agreement with BioSeek, Inc., we will make various payments based on the success and timing of the Company’s signing of a third party partnering agreement where the Company grants to the third party, directly or indirectly, any right or option to market, sell, distribute or otherwise commercialize a thiazolopyrimidine (TZP) product in any geographic territory. During the six months ended June 30, 2005, we paid BioSeek $0.3 million associated with the achievement of a contractual milestone.
     Under the terms of an agreement with Berna Biotech, we agreed to make certain commercialization and sales milestone payments to Berna regarding the Company’s hepatitis B vaccine. None of these milestones were achieved as of June 30, 2005.
Risk Factors
     Various statements in this Quarterly Report on Form 10-Q are forward-looking statements concerning our future products, expenses, revenues, liquidity and cash needs, as well as our plans and strategies. These forward-looking statements are based on current expectations and we assume no obligation to update this information. Numerous factors could cause our actual results to differ significantly from the results described in these forward-looking statements, including the following risk factors.
We have incurred substantial losses since inception and do not have any commercial products that generate revenue.
     We have experienced significant operating losses in each year since our inception in August 1996. Our revenue has resulted from a collaboration agreement and government and private agency grants. The UCB collaboration agreement ended in March 2005. The grants are subject to annual review based on the achievement of milestones and other factors and will terminate in 2006 at the latest. Our accumulated deficit was $98.8 million as of June 30, 2005, and we anticipate that we will incur substantial additional operating losses for the foreseeable future. These losses have been, and will continue to be, principally the result of the various costs associated with our research and development activities. We expect our losses to increase primarily as a consequence of our continuing product development efforts. Specifically, in 2004, we began a Phase II/III trial for AIC, an immunotherapy for ragweed allergy, and a Phase II/III trial for our hepatitis B vaccine. In 2005, we initiated a trial of AIC in ragweed allergic children designed to support our pivotal Phase III program and initiated a pivotal Phase III trial for our hepatitis B vaccine.
     We do not have any products that generate revenue. Our product candidates may never be commercialized, and we may never generate product-related revenue. Our ability to generate product revenue depends upon:
    demonstrating in clinical trials that our product candidates are safe and effective, in particular, in the planned Phase III trials for AIC and the current Phase III trial of our hepatitis B vaccine;
 
    obtaining regulatory approvals for our product candidates in the U.S. and international markets;
 
    entering into collaborative relationships on commercially reasonable terms for the development, manufacturing, sales and marketing of our product candidates, and then successfully managing these relationships; and
 
    obtaining commercial acceptance of our products, in particular AIC and our hepatitis B vaccine.
     If we are unable to generate revenues or achieve profitability, we may be required to significantly reduce or discontinue our operations or raise additional capital under adverse circumstances.
If we are unable to secure additional funding, we will have to reduce or discontinue operations.

18


Table of Contents

     We believe our existing capital resources will be adequate to satisfy our capital needs for at least the next twelve months. We expect capital outlays and operating expenditures to increase over the next several years as we expand our operations. Because of the significant time and resources it will take to develop our product candidates, potentially commercialize them and generate revenues, we may require substantial additional capital resources in order to continue our operations, and any such funding may not cover our costs of operations. We may also need to secure more funding than currently anticipated because we may change our product development plans or clinical programs.
     We may be unable to obtain additional capital from financing sources or from agreements with collaborators on acceptable terms, or at all. If at any time sufficient capital is not available, we may be required to delay, reduce the scope of, or eliminate some or all of our research, preclinical or clinical programs or discontinue our operations.
All of our product candidates are unproven, and our success depends on our product candidates being approved through uncertain and time-consuming regulatory processes. Failure to prove our products safe and effective in clinical trials and obtain regulatory approvals could require us to discontinue operations.
     None of our product candidates has been proven safe and effective in clinical trials or approved for sale in the U.S. or any foreign market. Any product candidate we develop is subject to extensive regulation by federal, state and local governmental authorities in the U.S., including the FDA, and by foreign regulatory agencies. Our success is primarily dependent on our ability to obtain regulatory approval for AIC, our ragweed allergy product candidate, and our hepatitis B vaccine product candidate. We intend to commercialize our hepatitis B vaccine initially outside the U.S., which will require us to seek approval from foreign regulatory agencies. Approval processes in the U.S. and in other countries are uncertain, take many years and require the expenditure of substantial resources. Product development failure can occur at any stage of clinical trials and as a result of many factors, many of which are not under our control.
     We will need to demonstrate in clinical trials that each product candidate is safe and effective before we can obtain the necessary approvals from the FDA and foreign regulatory agencies. We initiated a two-year, multi-site Phase II/III trial in the first quarter of 2004 in the U.S. for AIC. Pending the outcome of discussions with the FDA and the results of the Phase II/III study, we plan to initiate a pivotal Phase III AIC clinical program in early 2006. We have initiated a pivotal Phase III trial for our hepatitis B vaccine in Asia. We anticipate initiating a second pivotal Phase III trial in Canada and Europe in early 2006. The FDA or foreign regulatory agencies may require us to conduct additional clinical trials prior to approval in their jurisdictions.
     Many new drug candidates, including many drug candidates that have completed Phase III clinical trials, have shown promising results in early clinical trials and subsequently failed to establish sufficient safety and efficacy to obtain regulatory approval. Despite the time and money expended, regulatory approvals are never guaranteed. Failure to complete clinical trials and prove that our products are safe and effective would have a material adverse effect on our ability to eventually generate revenues and could require us to reduce the scope of or discontinue our operations.
Our clinical trials may be suspended, delayed or terminated at any time. Even short delays in the commencement and progress of our trials may lead to substantial delays in the regulatory approval process for our product candidates, which will impair our ability to generate revenues.
     We may suspend or terminate clinical trials at any time for various reasons, including regulatory actions by the FDA or foreign regulatory agencies, actions by institutional review boards, failure to comply with good clinical practice requirements and concerns regarding health risks to test subjects. In addition, our ability to conduct clinical trials for some of our product candidates, notably AIC, is limited due to the seasonal nature of ragweed allergy. Even a small delay in a trial for any product candidate could require us to delay commencement of the trial until the next appropriate season, which could result in a delay of an entire year. Consequently, we may experience additional delays in obtaining regulatory approval for these product candidates.
     Suspension, termination or unanticipated delays of our clinical trials for AIC or hepatitis B may:
    adversely affect our ability to commercialize or market any product candidates we may develop;
 
    impose significant additional costs on us;
 
    potentially diminish any competitive advantages that we may attain;

19


Table of Contents

    adversely affect our ability to enter into collaborations, receive milestone payments or royalties from potential collaborators;
 
    cause us to abandon the development of the affected product candidate; and
 
    limit our ability to obtain additional financing on acceptable terms, if at all.
If we receive regulatory approval for our product candidates, we will be subject to ongoing FDA and foreign regulatory obligations and continued regulatory review, which may be costly and subject us to various enforcement actions.
     Any regulatory approvals that we receive for our product candidates are likely to contain requirements for post-marketing follow-up studies, which may be costly. Product approvals, once granted, may be modified, resulting in limitations on our labeling indications or marketing claims, or withdrawn completely if problems occur after commercialization. Thus, even if we receive FDA and other regulatory approvals, our product candidates may later exhibit qualities that limit or prevent their widespread use or that force us to withdraw those products from the market.
     In addition, we or our contract manufacturers will be required to adhere to federal regulations setting forth current good manufacturing practice. The regulations require that our product candidates be manufactured and our records maintained in a prescribed manner with respect to manufacturing, testing and quality control activities. Furthermore, we or our contract manufacturers must pass a pre-approval inspection of manufacturing facilities by the FDA and foreign regulatory agencies before obtaining marketing approval and will be subject to periodic inspection by the FDA and corresponding foreign regulatory agencies under reciprocal agreements with the FDA. Further, to the extent that we contract with third parties for the manufacture of our products, our ability to control third-party compliance with FDA requirements will be limited to contractual remedies and rights of inspection.
     Failure to comply with regulatory requirements could prevent or delay marketing approval or require the expenditure of money or other resources to correct. Failure to comply with applicable requirements may also result in warning letters, fines, injunctions, civil penalties, recall or seizure of products, total or partial suspension of production, refusal of the government to renew marketing applications and criminal prosecution, any of which could be harmful to our ability to generate revenues and our stock price.
Our product candidates in clinical trials rely on a single lead ISS compound, 1018 ISS, and most of our earlier stage programs rely on ISS-based technology. Serious adverse safety data relating to either 1018 ISS or other ISS-based technology may require us to reduce the scope of or discontinue our operations.
     Our product candidates in clinical trials are based on 1018 ISS, and substantially all of our research and development programs use ISS-based technology. If any of our product candidates in clinical trials produce serious adverse safety data, we may be required to delay or discontinue all of our clinical trials. In addition, as all of our clinical product candidates contain 1018 ISS, potential collaborators may also be reluctant to establish collaborations for our products in distinct therapeutic areas due to the common safety risk across therapeutic areas. If adverse safety data are found to apply to our ISS-based technology as a whole, we may be required to discontinue our operations.
A key part of our business strategy is to establish collaborative relationships to commercialize and fund development of our product candidates. We may be unsuccessful in establishing and managing collaborative relationships, which may significantly limit our ability to develop and commercialize our products successfully, if at all.
     We will have to establish collaborative relationships to obtain domestic and international sales, marketing and distribution capabilities for our product candidates. We also intend to enter into collaborative relationships to provide funding to support our research and development programs. We have established a collaborative relationship with Berna Biotech for our hepatitis B vaccine and hepatitis B therapeutic product candidates. Our collaboration agreement with UCB for AIC and grass allergy immunotherapy ended in March 2005. Future collaboration revenue will be dependent on our ability to enter into new collaborative relationships.
     The process of establishing collaborative relationships is difficult, time-consuming and involves significant uncertainty. Moreover, even if we do establish collaborative relationships, our collaborators may seek to renegotiate or terminate their relationships with us due to unsatisfactory clinical results, a change in business strategy, a change of control or other reasons. If any collaborator fails to fulfill its responsibilities in a timely manner, or at all, our research, clinical development or commercialization efforts related to that collaboration could be delayed or terminated, or it may be necessary for us to assume responsibility for expenses or activities that would otherwise have been the responsibility of our collaborator. If we are unable to establish and maintain collaborative relationships

on acceptable terms, we may have to delay or discontinue further development of one or more of our product candidates, undertake development and commercialization activities at our own expense or find alternative sources of funding.
We rely on third parties to supply component materials necessary for our clinical product candidates and manufacture product candidates for our clinical trials. Loss of these suppliers or manufacturers, or failure to replace them may delay our clinical trials and research and development efforts and may result in additional costs, which would preclude us from producing our product candidates on commercially reasonable terms.
     We rely on contract relationships with third parties to obtain the component materials that are necessary for our clinical product candidates and to manufacture our product candidates for clinical trials. Termination or interruption of these relationships may occur due to circumstances that are outside our control, resulting in higher costs or delays in our product development efforts.
     In particular, we have relied on a single supplier to produce our ISS for clinical trials. ISS is a critical component of both of our AIC and hepatitis B vaccine product candidates. To date, we have manufactured only small quantities of ISS ourselves for research purposes. If we were unable to maintain or replace our existing source for ISS, we would have to establish an in-house ISS manufacturing capability, incurring increased capital and operating costs and delays in commercializing our product candidates. We or other third parties may not be able to produce ISS at a cost, quantity and quality that are available from our current third-party supplier.
     In addition, we do not currently have a contract manufacturer for AIC or sufficient AIC to supply our potential commercial needs. We believe that our existing supplies of AIC are sufficient for us to conduct our current Phase III clinical trial in ragweed allergic children. We intend to enter into manufacturing agreements with one or more commercial-scale contract manufacturers to produce additional supplies of AIC as required for new clinical trials and commercialization. If we are unable to complete such agreements, we would have to establish an internal commercial scale manufacturing capability for AIC, incurring increased capital and operating costs, delays in the commercial development of AIC and higher manufacturing costs than we have experienced to date.
We have or intend to contract with one or more third parties to conduct our clinical trials for AIC and our hepatitis B vaccine. If these third parties do not carry out their contractual obligations or meet expected deadlines, our planned clinical trials may be delayed and we may fail to obtain the regulatory approvals necessary to commercialize AIC or our hepatitis B vaccine.
     We are unable to independently conduct our planned clinical trials for AIC or our hepatitis B vaccine, and we have or intend to contract with third party contract research organizations to manage and conduct these trials. If these third parties do not carry out their contractual duties or obligations or meet expected deadlines, if the third parties need to be replaced or if the quality or accuracy of the clinical data they obtain is compromised due to failure to adhere to our clinical protocols or for other reasons, our planned clinical trials may be extended, delayed or terminated. Any extension, delay or termination of our trials would delay our ability to commercialize AIC or our hepatitis B vaccine and generate revenues.
If any products we develop are not accepted by the market or if regulatory agencies limit our labeling indications or marketing claims, we may be unable to generate significant revenues, if any.
     We do not anticipate that any of our product candidates will be commercially available until 2008 at the earliest, if at all. Furthermore, even if we obtain regulatory approval for our product candidates and are able to successfully commercialize them, our product candidates may not gain market acceptance among physicians, patients, health care payors and the medical community. The FDA or other regulatory agencies could limit the labeling indication for which our product candidates may be marketed or could otherwise constrain our marketing claims, reducing our or our collaborators’ ability to market the benefits of our products to particular patient populations. If we are unable to successfully market any approved product candidates, or are limited in our marketing efforts by regulatory limits on labeling indications or marketing claims, our ability to generate revenues could be significantly impaired.
     In particular, treatment with AIC, if approved, will require a series of injections, and we expect that some of the patients that currently take oral or inhaled pharmaceutical products to treat their allergies would not consider using our product. We believe that market acceptance of AIC will also depend on our ability to offer competitive pricing, increased efficacy and improved ease of use as compared to existing or potential new allergy treatments.
     While we may seek partners for purposes of commercialization of our hepatitis B vaccine in selected markets worldwide in addition to or as a replacement for our current collaborative partner, which has an exclusive option to commercialize our hepatitis B vaccine and therapeutic product candidates, marketing challenges vary by market and could limit or delay acceptance in any particular

21


Table of Contents

country. We believe that market acceptance of our hepatitis B vaccine will depend on our ability to offer increased efficacy and improved ease of use as compared to existing or potential new hepatitis B vaccine products.
We face uncertainty related to coverage, pricing and reimbursement and the practices of third party payors, which may make it difficult or impossible to sell our product candidates on commercially reasonable terms.
     In both domestic and foreign markets, our ability to generate revenues from the sales of any approved product candidates in excess of the costs of producing the product candidates will depend in part on the availability of reimbursement from third party payors. Existing laws affecting the pricing and coverage of pharmaceuticals and other medical products by government programs and other third party payors may change before any of our product candidates are approved for marketing. In addition, third party payors are increasingly challenging the price and cost-effectiveness of medical products and services. Significant uncertainty therefore exists as to coverage and reimbursement levels for newly approved health care products, including pharmaceuticals. Because we intend to offer products, if approved, that involve new technologies and new approaches to treating disease, the willingness of third party payors to reimburse for our products is particularly uncertain. We will have to charge a price for our products that is sufficiently high to enable us to recover the considerable capital resources we have spent and will continue to spend on product development. Adequate third-party reimbursement may not be available to enable us to maintain price levels sufficient to realize a return on our investment in product development. If it becomes apparent, due to changes in coverage or pricing of pharmaceuticals in our market or a lack of reimbursement, that it will be difficult, if not impossible, for us to generate revenues in excess of costs, we will need to alter our business strategy significantly. This could result in significant unanticipated costs, harm our future prospects and reduce our stock price.
Many of our competitors have greater financial resources and expertise than we do. If we are unable to successfully compete with existing or potential competitors despite these disadvantages we may be unable to generate revenues and our business will be harmed.
     We compete with many companies and institutions, including pharmaceutical companies, biotechnology companies, academic institutions and research organizations, in developing alternative therapies to treat or prevent allergy, infectious diseases, asthma and cancer, as well as those focusing more generally on the immune system. Competitors may develop more effective, more affordable or more convenient products or may achieve earlier patent protection or commercialization of their products. These competitive products may render our product candidates obsolete or limit our ability to generate revenues from our product candidates. Many of the companies developing competing technologies and products have significantly greater financial resources and expertise in research and development, manufacturing, preclinical and clinical testing, obtaining regulatory approvals and marketing than we do.
     AIC, if approved, will compete directly with conventional allergy shots and indirectly with antihistamines, corticosteroids and anti-leukotriene agents, which manage seasonal allergy symptoms, including those produced by GlaxoSmithKline Plc, Merck & Co., Inc. and AstraZeneca Plc. Since our AIC ragweed allergy treatment would require a series of injections, we expect that some patients that currently take oral or inhaled pharmaceutical products to treat their allergies would not consider our product.
     Our hepatitis B vaccine, if approved, will compete with existing vaccines produced by GlaxoSmithKline Plc and Merck & Co., Inc., among others.
     Existing and potential competitors may also compete with us for qualified scientific and management personnel, as well as for technology that would be advantageous to our business. If we are unable to compete with existing and potential competitors we may not be able to obtain financing, sell our product candidates or generate revenues.
We depend on key employees in a competitive market for skilled personnel, and the loss of the services of any of our key employees would affect our ability to develop and commercialize our product candidates and achieve our objectives.
     We are highly dependent on the principal members of our management, operations and scientific staff. We experience intense competition for qualified personnel. Our future success also depends in part on the continued service of our executive management team, key scientific and management personnel and our ability to recruit, train and retain essential scientific personnel for our drug discovery and development programs, including those who will be responsible for overseeing our preclinical testing and clinical trials as well as for the establishment of collaborations with other companies. If we lose the services of any of these people, our research and product development goals, including the identification and establishment of key collaborations, operations and marketing efforts could be delayed or curtailed.
We intend to develop, seek regulatory approval for and market our product candidates outside the U.S., requiring a significant commitment of resources. Failure to successfully manage our international operations could result in significant

22


Table of Contents

unanticipated costs and delays in regulatory approval or commercialization of our hepatitis B vaccine and therapeutic product candidates.
     We plan to introduce our hepatitis B vaccine in various markets initially outside the U.S. Developing, seeking regulatory approval for and marketing our product candidates outside the U.S. could impose substantial burdens on our resources and divert management’s attention from domestic operations. We may also conduct operations in other foreign jurisdictions.
     International operations are subject to risk, including:
    the difficulty of managing geographically distant operations, including recruiting and retaining qualified employees, locating adequate facilities and establishing useful business support relationships in the local community;
 
    compliance with varying international regulatory requirements;
 
    securing international distribution, marketing and sales capabilities;
 
    adequate protection of our intellectual property rights;
 
    difficulties and costs associated with complying with a wide variety of complex international laws and treaties;
 
    legal uncertainties and potential timing delays associated with tariffs, export licenses and other trade barriers;
 
    adverse tax consequences;
 
    the fluctuation of conversion rates between foreign currencies and the U.S. dollar; and
 
    geopolitical risks.
     If we are unable to successfully manage our international operations, we may incur significant unanticipated costs and delays in regulatory approval or commercialization of our hepatitis B vaccine and therapeutic product candidates, as well as other product candidates that we may choose to commercialize internationally, which would impair our ability to generate revenues.
We use hazardous materials in our business. Any claims or liabilities relating to improper handling, storage or disposal of these materials could be time consuming and costly to resolve.
     Our research and product development activities involve the controlled storage, use and disposal of hazardous and radioactive materials and biological waste. We are subject to federal, state and local laws and regulations governing the use, manufacture, storage, handling and disposal of these materials and certain waste products. We are currently in compliance with all government permits that are required for the storage, use and disposal of these materials. However, we cannot eliminate the risk of accidental contamination or injury to persons or property from these materials. In the event of an accident related to hazardous materials, we could be held liable for damages, cleanup costs or penalized with fines, and this liability could exceed the limits of our insurance policies and exhaust our internal resources. We may have to incur significant costs to comply with future environmental laws and regulations.
We face product liability exposure, which, if not covered by insurance, could result in significant financial liability.
     While we have not experienced any product liability claims to date, the use of any of our product candidates in clinical trials and the sale of any approved products will subject us to potential product liability claims and may raise questions about a product’s safety and efficacy. As a result, we could experience a delay in our ability to commercialize one or more of our product candidates or reduced sales of any approved product candidates. In addition, a product liability claim may exceed the limits of our insurance policies and exhaust our internal resources. We have obtained limited product liability insurance coverage in the amount of $1 million for each occurrence for clinical trials with umbrella coverage of an additional $4 million. This coverage may not be adequate or may not continue to be available in sufficient amounts, at an acceptable cost or at all. We also may not be able to obtain commercially reasonable product liability insurance for any product approved for marketing in the future. A product liability claim, product recalls or other claims, as well as any claims for uninsured liabilities or in excess of insured liabilities, would divert our management’s attention from our business and could result in significant financial liability.

If the combination of patents, trade secrets and contractual provisions that we rely on to protect our intellectual property is inadequate, the value of our product candidates will decrease.
     Our success depends on our ability to:
    obtain and protect commercially valuable patents or the rights to patents both domestically and abroad;
 
    operate without infringing upon the proprietary rights of others; and
 
    prevent others from successfully challenging or infringing our proprietary rights.
     We will be able to protect our proprietary rights from unauthorized use only to the extent that these rights are covered by valid and enforceable patents or are effectively maintained as trade secrets. We try to protect our proprietary rights by filing and prosecuting U.S. and foreign patent applications. Legal standards relating to the validity and scope of patent claims in the biopharmaceutical field can be highly uncertain, are still evolving and involve complex legal and factual questions for which important legal principles remain unresolved. The biopharmaceutical patent environment outside the U.S. is even more uncertain. We may be particularly affected by this uncertainty, given that several of our product candidates may address market opportunities outside the U.S. For example, we expect to market our hepatitis B vaccine, if approved, in various countries with high incidences of hepatitis B, including Canada, Europe and selected markets in Asia. The risks and uncertainties that we face with respect to our patents and other proprietary rights include the following:
    we might not have been the first to make the inventions covered by each of our pending patent applications and issued patents;
 
    we might not have been the first to file patent applications for these inventions;
 
    the pending patent applications we have filed or to which we have exclusive rights may not result in issued patents or may take longer than we expect to result in issued patents;
 
    the claims of any patents that are issued may not provide meaningful protection;
 
    our issued patents may not provide a basis for commercially viable products or may not be valid or enforceable;
 
    we might not be able to develop additional proprietary technologies that are patentable;
 
    the patents licensed or issued to us or our collaborators may not provide a competitive advantage;
 
    patents issued to other companies, universities or research institutions may harm our ability to do business;
 
    other companies, universities or research institutions may independently develop similar or alternative technologies or duplicate our technologies and commercialize discoveries that we attempt to patent; and
 
    other companies, universities or research institutions may design around technologies we have licensed, patented or developed.
     We also rely on trade secret protection and confidentiality agreements to protect our interests in proprietary know-how that is not patentable and for processes for which patents are difficult to enforce. We cannot be certain that we will be able to protect our trade secrets adequately. Any leak of confidential data into the public domain or to third parties could allow our competitors to learn our trade secrets. If we are unable to adequately obtain or enforce proprietary rights we may be unable to commercialize our products, enter into collaborations, generate revenues or maintain any advantage we may have with respect to existing or potential competitors.
If third parties successfully assert that we have infringed their patents and proprietary rights or challenge the validity of our patents and proprietary rights, we may become involved in intellectual property disputes and litigation that would be costly, time consuming, and delay or prevent development of our product candidates.
     We may be exposed to future litigation by third parties based on claims that our product candidates, proprietary technologies or the licenses on which we rely, infringe their intellectual property rights, or we may be required to enter into litigation to enforce patents issued or licensed to us or to determine the scope or validity of another party’s proprietary rights. If we become involved in any

24


Table of Contents

litigation, interference or other administrative proceedings related to our intellectual property or the intellectual property of others, we will incur substantial expenses and it will divert the efforts of our technical and management personnel. Others may succeed in challenging the validity of our issued and pending claims. If we are unsuccessful in defending or prosecuting any such claim we could be required to pay substantial damages and we may be unable to commercialize our product candidates or use these proprietary technologies unless we obtain a license from the third party. A license may require us to pay substantial royalties, require us to grant a cross-license to our technology or may not be available to us on acceptable terms. In addition, we may be required to redesign our technology so it does not infringe a third party’s patents, which may not be possible or could require substantial funds and time. Any of these outcomes may require us to change our business strategy and could reduce the value of our business.
     In particular, one of our potential competitors, Coley Pharmaceutical Group (Coley), has issued U.S. patent claims, as well as patent claims pending with the U.S. Patent and Trademark Office, that, if held to be valid, could require us to obtain a license in order to commercialize one or more of our formulations of ISS in the U.S., including AIC. In December 2003 the U.S. Patent and Trademark Office declared an interference to resolve first-to-invent disputes between a patent application filed by the Regents of the University of California, which is exclusively licensed to us, and an issued U.S. patent owned by Coley relating to immunostimulatory DNA sequences. The declaration of interference names the Regents of the University of California as senior party, indicating that a patent application filed by the Regents of the University of California and licensed to us was filed prior to a patent application owned by Coley that led to an issued U.S. patent. The interference provides the first forum to challenge the validity and priority of certain of Coley’s patents. If successful, the interference action would establish our founders as the inventors of the inventions in dispute. On March 10, 2005, the U.S. Patent and Trademark Office issued a decision in the interference which did not address the merits of the case, but dismissed it on a legal technicality related to the timing of Dynavax’s filing of its claims and request for interference. Dynavax has appealed this non-final decision. If we do not prevail in the interference proceeding, we may not be able to obtain patent protection on the subject matter of the interference, which would have a material adverse impact on our business. In addition, if Coley prevails in the interference, it may seek to enforce its rights under issued claims, including, for example, by suing us for patent infringement. Consequently, we may need to obtain a license to issued and/or pending claims held by Coley by paying cash, granting royalties on sales of our products or offering rights to our own proprietary technologies. Such a license may not be available to us on acceptable terms, if at all.
We rely on our licenses from the Regents of the University of California. Impairment of these licenses or our inability to maintain them would severely harm our business.
     Our success depends upon our license arrangements with the Regents of the University of California. These licenses are critical to our research and product development efforts. Our dependence on these licenses subjects us to numerous risks, such as disputes regarding the invention and corresponding ownership rights in inventions and know-how resulting from the joint creation or use of intellectual property by us and the Regents of the University of California, or scientific collaborators. Additionally, our agreements with the Regents of the University of California generally contain diligence or milestone-based termination provisions. Our failure to meet any obligations pursuant to these provisions could allow the Regents of the University of California to terminate any of these licensing agreements or convert them to non-exclusive licenses. In addition, our license agreements with the Regents of the University of California may be terminated or may expire by their terms, and we may not be able to maintain the exclusivity of these licenses. If we cannot maintain licenses that are advantageous or necessary to the development or the commercialization of our product candidates, we may be required to expend significant time and resources to develop or license similar technology.
Our stock price is subject to volatility, and your investment may suffer a decline in value.
     The market prices for securities of biopharmaceutical companies have in the past been, and are likely to continue in the future to be, very volatile. The market price of our common stock is subject to substantial volatility depending upon many factors, many of which are beyond our control, including:
    progress or results of any of our clinical trials, in particular any announcements regarding the progress or results of our planned Phase III trials for AIC and our hepatitis B vaccine;
 
    progress of regulatory approval of our product candidates, in particular AIC and our hepatitis B vaccine, and compliance with ongoing regulatory requirements;
 
    our ability to establish collaborations for the development and commercialization of our product candidates;
 
    market acceptance of our product candidates;

25


Table of Contents

    our ability to raise additional capital to fund our operations, whether through the issuance of equity securities or debt;
 
    technological innovations, new commercial products or drug discovery efforts and preclinical and clinical activities by us or our competitors;
 
    changes in our intellectual property portfolio or developments or disputes concerning the proprietary rights of our products or product candidates;
 
    our ability to obtain component materials and successfully enter into manufacturing relationships for our product candidates or establish manufacturing capacity on our own;
 
    our ability to form strategic partnerships or joint ventures;
 
    maintenance of our existing licensing agreements with the Regents of the University of California;
 
    changes in government regulations;
 
    issuance of new or changed securities analysts’ reports or recommendations;
 
    general economic conditions and other external factors;
 
    actual or anticipated fluctuations in our quarterly financial and operating results; and
 
    degree of trading liquidity in our common stock.
     One or more of these factors could cause a decline in the price of our common stock. In addition, securities class action litigation has often been brought against a company following a decline in the market price of its securities. We may in the future be the target of similar litigation. Securities litigation could result in substantial costs, divert management’s attention and resources and disrupt our business operations.
If the ownership of our common stock continues to be highly concentrated, it may prevent stockholders from influencing significant corporate decisions and may result in conflicts of interest that could cause our stock price to decline.
     Our executive officers, directors and their affiliates beneficially owned or controlled approximately 19% of our outstanding common stock as of June 30, 2005. Accordingly, these executive officers, directors and their affiliates, acting as a group, will have substantial influence over the outcome of corporate actions requiring stockholder approval, including the election of directors, any merger, consolidation or sale of all or substantially all of our assets or any other significant corporate transactions. These stockholders may also delay or prevent a change of control of us, even if such a change of control would benefit our other stockholders. The significant concentration of stock ownership may adversely affect the trading price of our common stock due to investors’ perception that conflicts of interest may exist or arise.
Anti-takeover provisions of our certificate of incorporation, bylaws and Delaware law may prevent or frustrate a change in control, even if an acquisition would be beneficial to our stockholders, which could affect our stock price adversely and prevent attempts by our stockholders to replace or remove our current management.
     Provisions of our certificate of incorporation and bylaws may delay or prevent a change in control, discourage bids at a premium over the market price of our common stock and adversely affect the market price of our common stock and the voting or other rights of the holders of our common stock. These provisions include:
    authorizing our Board of Directors to issue additional preferred stock with voting rights to be determined by the Board of Directors;
 
    limiting the persons who can call special meetings of stockholders;
 
    prohibiting stockholder actions by written consent;

26


Table of Contents

    creating a classified board of directors pursuant to which our directors are elected for staggered three year terms;
 
    providing that a supermajority vote of our stockholders is required for amendment to certain provisions of our certificate of incorporation and bylaws; and
 
    establishing advance notice requirements for nominations for election to our Board of Directors or for proposing matters that can be acted on by stockholders at stockholder meetings.
     In addition, we are subject to the provisions of the Delaware corporation law that, in general, prohibit any business combination with a beneficial owner of 15% or more of our common stock for five years unless the holder’s acquisition of our stock was approved in advance by our board of directors.
We will need to implement additional finance and accounting systems, procedures and controls as we grow our business and organization and to satisfy new reporting requirements.
     As a public company, we are required to comply with the Sarbanes-Oxley Act of 2002 and the related rules and regulations of the SEC, including expanded disclosures and accelerated reporting requirements and more complex accounting rules. Compliance with Section 404 of the Sarbanes-Oxley Act of 2002 and other requirements will increase our costs and require additional management resources. We may need to continue to implement additional finance and accounting systems, procedures and controls as we grow our business and organization and to comply with new reporting requirements. Compliance with Section 404 will apply in 2005, and Section 404 reporting will first occur in our Form 10-K for our fiscal year ending December 31, 2005. There can be no assurance that we will be able to complete a favorable assessment as to the adequacy of our internal control reporting.
The adoption of Statement of Financial Accounting Standard No. 123R and changes to existing accounting pronouncements, rules or practices may affect how we conduct our business and affect our reported financial results.
     On December 16, 2004, the Financial Accounting Standards Board issued Financial Accounting Standard (FAS) No. 123R (revised 2004), "Share-Based Payment" which will require us to measure compensation costs for all stock-based compensation at fair value. We will adopt FAS No. 123R as of January 1, 2006. Adoption of FAS No. 123R could have a material impact on our financial statements, as we will be required to record compensation expense in our statement of operations for stock option grants and stock purchases under our employee stock purchase plan, rather than disclose the impact on our net loss within our footnotes, as is our current practice. The impact of adoption of FAS No. 123R cannot be predicted at this time because it will depend on levels of share-based payments granted in the future. Changes to existing rules, current practices, or future changes, if any, may adversely affect our reported financial results or the way we conduct our business.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
     The primary objective of our investment activities is to preserve principal while at the same time maximize the income we receive from our investments without significantly increasing risk. Some of the securities that we invest in may have market risk. This means that a change in prevailing interest rates may cause the principal amount of the investment to fluctuate. To minimize this risk, we maintain our portfolio of cash equivalents and investments in a variety of securities, including commercial paper, money market funds, government and non-government debt securities and corporate obligations. Because of the short-term maturities of our cash equivalents and marketable securities, we do not believe that an increase in market rates would have any significant negative impact on the realized value of our investments.
     Interest Rate Risk. We do not use derivative financial instruments in our investment portfolio. Due to the short duration and conservative nature of our cash equivalents and marketable securities, we do not expect any material loss with respect to our investment portfolio.
     Foreign Currency Risk. We have no significant investments outside the U.S. and have nominal transactional foreign currency risk because nearly all of our business is transacted in U.S. dollars. As a result, we currently have little exposure to foreign exchange rate fluctuations.
ITEM 4A. CONTROLS AND PROCEDURES
(a) Evaluation of disclosure controls and procedures
     The Company’s management, under the supervision and with the participation of the Company’s Chief Executive Officer (CEO) and Chief Financial Officer (CFO), performed an evaluation of the effectiveness of the design and operation of the Company’s disclosure controls and procedures as of the end of the period covered by this report. Based on that evaluation, the CEO and CFO concluded that the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”)) as of the end of period covered by this report have been designed and are functioning effectively to provide reasonable assurance that the information required to be disclosed by us in reports filed under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms. We believe that a control system, no matter how well designed and operated, cannot provide absolute assurance that the objectives of the control system are met, and no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within a company have been detected.
(b) Changes in internal controls
     No changes in the Company’s internal control over financial reporting occurred during the Company’s last fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

     None.
ITEM 2. USE OF PROCEEDS FROM SALES OF REGISTERED SECURITIES
     On February 24, 2004, we completed our initial public offering of 6,900,000 shares of common stock, including 900,000 shares subject to the underwriters’ over-allotment option (which was exercised in full) at a public offering price of $7.50 per share and realized an aggregate offering price of $51.8 million. Our registration statement on Form S-1 (Reg. No. 333-109965) was declared effective by the SEC on February 11, 2004. The underwriters for the initial public offering were Bear, Stearns & Co. Inc., Deutsche Bank Securities Inc. and Piper Jaffray & Co.
     We received net proceeds from the offering of approximately $46.5 million. These proceeds are net of $3.6 million in underwriting discounts and commissions, $1.4 million in legal, accounting and printing fees and $0.3 million in other expenses. We used $0.4 million of the net proceeds to make a one-time cash payment to the University of California pursuant to the terms of several license agreements with them. During 2004, the net proceeds were used for research and development activities and general corporate purposes. We will retain broad discretion over the use of the net proceeds received from our offering. The amount and timing of our actual expenditures may vary significantly depending on numerous factors, such as the progress of our product candidate development and commercialization efforts and the amount of cash used by our operations.
ITEM 3. DEFAULTS UPON SENIOR SECURITIES
     None.
