Notes to Condensed Consolidated Financial Statements

(Unaudited)

1. Organization and Summary of Significant Accounting Policies

Dynavax Technologies Corporation (“Dynavax” or the “Company”), a clinical-stage biopharmaceutical company, discovers and develops novel products to prevent and treat infectious diseases. Our lead product candidate is HEPLISAV^TM, a Phase 3 investigational adult hepatitis B vaccine. We originally incorporated in California on August 29, 1996 under the name Double Helix Corporation, and we changed our name to Dynavax Technologies Corporation in September 1996. We reincorporated in Delaware on March 26, 2001.

Basis of Presentation

Our accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. 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 or any other interim-period. The condensed consolidated balance sheet at December 31, 2008 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, 2008 as filed with the Securities and Exchange Commission (“SEC”).

The unaudited condensed consolidated financial statements include the accounts of Dynavax and our wholly-owned subsidiary, Rhein Biotech GmbH (“Rhein” or “Dynavax Europe”), as well as the accounts of a variable interest entity, Symphony Dynamo, Inc. (“SDI”), which we consolidate pursuant to Financial Accounting Standards Board Interpretation No. 46 (revised 2003), “Consolidation of Variable Interest Entities” (“FIN 46R”). All significant intercompany accounts and transactions have been eliminated. We operate in one business segment, which is the discovery and development of biopharmaceutical products. We have evaluated all subsequent events through August 6, 2009, the date the financial statements were filed with the SEC.

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the unaudited condensed consolidated financial statements and accompanying notes. Actual results may differ from these estimates.

Significant Accounting Policies

The Company believes that there have been no significant changes in its critical accounting policies during the six months ended June 30, 2009 as compared with those disclosed in its Annual Report on Form 10-K for the year ended December 31, 2008, except as discussed below with regards to the Company’s adoption of Statement of Financial Accounting Standards (“SFAS”) 160, “Noncontrolling Interests in Consolidated Financial Statements – an amendment of Accounting Research Bulletin No. 51” (“SFAS 160”) effective January 1, 2009.

In December 2007, the Financial Accounting Standards Board (“FASB”) issued SFAS 160, which establishes accounting and reporting standards for ownership interests in subsidiaries held by parties other than the parent, the amount of consolidated net income attributable to the parent and to the noncontrolling interest, changes in a parent’s ownership interest and the valuation of retained noncontrolling equity investments when a subsidiary is deconsolidated. SFAS 160 also establishes disclosure requirements that clearly identify and distinguish between the interests of the parent and the interests of the noncontrolling owners. We adopted SFAS 160 as of January 1, 2009 and our adoption did not impact our financial statements, except for the presentation and disclosure requirements affecting all periods presented as follows:

•

The noncontrolling interest in SDI has been reclassified to equity.

•

Consolidated net income or loss has been adjusted to include the net income or loss attributed to the noncontrolling interest in SDI.

•

Consolidated comprehensive income or loss has been adjusted to include the comprehensive income or loss attributed to the noncontrolling interest in SDI.

•

The Company must disclose for each reporting period the amounts of consolidated income or loss attributed to the Company and to the noncontrolling interest in SDI. In addition, for each reporting period the Company must present a reconciliation at the beginning and end of the period of the carrying amount of total equity and equity attributable to the Company and to the noncontrolling interest in SDI.

Recent Accounting Pronouncements

In December 2007, the FASB ratified the final consensus in Emerging Issues Task Force (“EITF”) Issue No. 07-1, “Accounting for Collaboration Agreements” (“EITF 07-1”) which required certain income statement presentation of transactions with third parties and of payments between parties to the collaboration arrangement, along with disclosure about the nature of the arrangement. EITF 07-1 is effective on a retrospective basis to all prior periods presented for collaborative arrangements existing as of the adoption date and impacts all financial statements issued for the fiscal years beginning after December 15, 2008. We adopted EITF 07-1 on January 1, 2009 and our adoption did not have a material effect on our consolidated results of operations or financial condition.

In December 2007, the FASB issued SFAS No. 141 (revised 2007), “Business Combinations” (“SFAS 141R”). SFAS 141R establishes principles and requirements for recognizing and measuring assets acquired, liabilities assumed and any noncontrolling interests in the acquiree in a business combination. SFAS 141R also provides guidance for recognizing and measuring goodwill acquired in a business combination; requires purchased in-process research and development to be capitalized at fair value as intangible assets at the time of acquisition; requires acquisition-related expenses and restructuring costs to be recognized separately from the business combination; expands the definition of what constitutes a business; and requires the acquirer to disclose information that users may need to evaluate and understand the financial effect of the business combination. SFAS 141R is effective on a prospective basis and will impact business combination transactions for which the acquisition date occurs after December 15, 2008. Depending on the nature and magnitude of our future business combination transactions, SFAS 141R may have a material impact on our consolidated financial position and/or results of operations.

In February 2008, the FASB issued FASB Staff Position No. (“FSP”) No. FAS 157-2, “Effective Date of FASB Statement No. 157”, which provides a one year deferral of the effective date of SFAS No. 157, Fair Value Measurements (“SFAS 157”) for non-financial assets and non-financial liabilities, except those that are recognized or disclosed in the financial statements at fair value at least annually. Therefore effective January 1, 2009, we implemented SFAS 157 for our nonfinancial assets and liabilities that are remeasured at fair value on a non-recurring basis. The adoption of SFAS 157 for our nonfinancial assets and liabilities that are remeasured at fair value on a non-recurring basis did not impact our financial position or results of operations.

In April 2009, the FASB issued FSP No. SFAS 107-1 and Accounting Principles Board Opinion (“APB”) APB 28-1, “Interim Disclosure about Fair Value of Financial Instruments” (“FSP 107-1/APB 28-1”). FSP 107-1/APB 28-1 requires interim disclosures regarding the fair values of financial instruments that are within the scope of FASB No. 107, “Disclosures about the Fair Value of Financial Instruments”. Additionally, FSP 107-1/APB 28-1 requires disclosure of the methods and significant assumptions used to estimate the fair value of financial instruments on an interim basis as well as changes of the methods and significant assumptions from prior periods. FSP 107-1/APB 28-1 does not change the accounting treatment for these financial instruments and is effective for interim reporting periods ending after June 15, 2009. There was no impact to our consolidated financial position, results of operations or cash flows as a result of adoption of this pronouncement.

In April 2009, the FASB issued FSP FAS 115-2 and FAS 124-2, “Recognition and Presentation of Other-Than-Temporary Impairments” (“FSP FAS 115-2/124-2”). FSP FAS 115-2/124-2 extends existing disclosure requirements about debt and equity securities to interim reporting periods and provides new disclosure requirements. FSP FAS 115-2/124-2 is effective for interim reporting periods ending after June 15, 2009 and we adopted FSP FAS 115-2/124-2 in the second quarter of 2009. There was no impact to our consolidated financial position, results of operations or cash flows as a result of adoption of this pronouncement. We expanded our disclosures regarding our available-for-sale securities, as discussed in Note 3.

In May 2009, the FASB issued SFAS No. 165, “Subsequent Events” (“SFAS 165”), to establish general standards of accounting for and disclosure of events that occur after the balance sheet date but before financial statements are issued or are available to be issued. It requires the disclosure of the date through which an entity has evaluated subsequent events and the basis for that date; that is, whether that date represents the date the financial statements were issued or were available to be issued. SFAS 165 is effective for interim or annual financial periods ending after June 15, 2009 and we adopted SFAS 165 in the second quarter of 2009. There was no impact to our consolidated financial position, results of operations or cash flows as a result of adoption of this pronouncement. We expanded our disclosures regarding subsequent events, as discussed in Note 1.

In June 2009, the FASB issued SFAS No. 167, “Amendments to FASB Interpretation No. 46(R)” (“SFAS 167”), which changes the consolidation guidance applicable to a variable interest entity (“VIE”). It also amends the guidance governing the determination of whether an enterprise is the primary beneficiary of a VIE, and is therefore required to consolidate a VIE, by requiring a qualitative analysis rather than a quantitative analysis. The qualitative analysis will include, among other things, consideration of who has the power to direct the activities of the entity that most significantly impact the entity’s economic performance and who has the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to the VIE. This standard also requires continuous reassessments of whether an enterprise is the primary beneficiary of a VIE. Previously, FIN 46R required reconsideration of whether an enterprise was the primary beneficiary of a VIE only when specific events had occurred. Qualifying Special Purpose Entities (“QSPEs”), which were previously exempt from the application of this standard, will be subject to the provisions of this standard when it becomes effective. SFAS 167 also requires enhanced disclosures about an enterprise’s involvement with a VIE. SFAS 167 will be effective for the first annual reporting periods that begin after November 15, 2009 and we will adopt it in the first quarter of fiscal 2010. We do not expect the adoption of SFAS 167 to have a material effect on our consolidated results of operations and financial condition.

2. Fair Value Measurements

SFAS 157 defines fair value, establishes a framework for measuring fair value under generally accepted accounting principles and enhances disclosures about fair value measurements. Fair value is defined under SFAS 157 as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value under SFAS 157 must maximize the use of observable inputs and minimize the use of unobservable inputs. The standard describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value, which are the following:

•

Level 1 - Quoted prices in active markets for identical assets or liabilities;

•

Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and

•

Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

In accordance with SFAS 157, the following table represents the fair value hierarchy for our financial assets (cash equivalents and marketable securities) and investments held by SDI measured at fair value on a recurring basis as of June 30, 2009 (in thousands):


	Level 1		Level 2		Level 3		Total
Money market funds	$	36,500	$	—	$	—	$	36,500
U.S. Government agency securities		—		5,786		—		5,786
FDIC insured corporate debt securities		—		4,249		—		4,249

Total	$	36,500	$	10,035	$	—	$	46,535

3. Available-for-Sale Securities

We consider all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Management determines the appropriate classification of marketable securities at the time of purchase. We invest in short-term money market funds, government agency securities and corporate obligations, some of which are government-secured. We believe these types of investments are subject to minimal credit and market risk. We do not invest in auction rate securities or securities collateralized by home mortgages, mortgage bank debt, or home equity loans.

We have classified our entire investment portfolio as available-for-sale. We view our available-for-sale portfolio as available for use in current operations, and accordingly, have classified all investments as short-term. As of June 30, 2009 the stated maturity of our investments is within one year of the current balance sheet date. In accordance with SFAS No. 115, “Accounting for Certain Investments in Debt and Equity Securities,” available-for-sale securities are carried at fair value based on quoted market prices, with unrealized gains and losses included in accumulated other comprehensive income in stockholders’ equity. Realized gains and losses and declines in value, if any, judged to be other than temporary on available-for-sale securities are included in interest income or expense. The cost of securities sold is based on the specific identification method. Management assesses whether declines in the fair value of investment securities are other than temporary. In determining whether a decline is other than temporary, management considers the following factors:

•

Length of the time and the extent to which the market value has been less than cost;

•

The financial condition and near-term prospects of the issuer; and

•

Our intent and ability to retain our investment in the issuer for a period of time sufficient to allow for any anticipated recovery in market value.

To date, there have been no declines in fair value that have been identified as other than temporary.

The following is a summary of available-for-sale securities included in cash and cash equivalents, marketable securities, investments held by SDI and restricted cash as of June 30, 2009 (in thousands):


June 30, 2009:	Amortized Cost		Unrealized Gains		Unrealized Losses		Aggregated Fair Value
Certificate of deposits and money market funds	$	37,333	$	—	$	—	$	37,333
U.S. Government agency securities		5,785		1		—		5,786
FDIC insured corporate debt securities		4,248		1		—		4,249

Total	$	47,366	$	2	$	—	$	43,768

There were no realized gains or losses from the sale of marketable securities for the three and six months ended June 30, 2009. We recognized immaterial realized gains and no realized losses for the three and six months ended June 30, 2008. Additionally, there was no other-than-temporary impairment recognized for the three and six months ended June 30, 2009 and 2008. As of June 30, 2009, all of our investments have a stated maturity date that is within one year of the current balance sheet date. All of our investments are classified as short-term and available-for-sale, as we may not hold our investments until maturity. As of June 30, 2009, our marketable securities had the following maturities (in thousands):


Maturities:	Amortized Cost		Aggregated Fair Value
Within 1 year	$	47,366	$	43,768
Total	$	47,366	$	43,768

4. Intangible Assets

Intangible assets consist primarily of the manufacturing process and customer relationships. The manufacturing process derives from the methods for making proteins in Hansenula yeast, which is a key component in the production of hepatitis B vaccine. The customer relationships derive from Rhein’s ability to sell existing, in-process and future products to its existing customers. Purchased intangible assets other than goodwill are amortized on a straight-line basis over their respective useful lives. The following tables present details of the purchased intangible assets at June 30, 2009 (in thousands, except years):


	Original Estimated Useful Life (in Years)	Gross		Accumulated Amortization			Net

5. Symphony Dynamo, Inc.

In April 2006, we entered into a series of related agreements with Symphony Capital Partners, LP and certain of its affiliates (“Symphony”) to advance specific Dynavax ISS-based programs for cancer, hepatitis B therapy and hepatitis C therapy through certain stages of clinical development (the “Development Programs”). The material agreements included:

•

the Amended and Restated Limited Liability Corporation Agreement of Symphony Dynamo Holdings LLC (the “LLC Agreement”);

•

the Funding Agreement by and among Dynavax Technologies Corporation, Symphony Capital Partners LP, Symphony Dynamo Holdings LLC, and Symphony Dynamo Investors LLC (the “Funding Agreement”);

•

the Amended and Restated Research and Development Agreement among Dynavax Technologies Corporation, Symphony Dynamo Holdings LLC and Symphony Dynamo, Inc. (the “R&D Agreement”);

•

the Novated and Restated Technology License Agreement among Dynavax Technologies Corporation, Symphony Dynamo Holdings LLC and Symphony Dynamo, Inc. (the “License Agreement”);

•

the Purchase Option Agreement among Dynavax Technologies Corporation, Symphony Dynamo Holdings LLC and Symphony Dynamo, Inc.;

•

the Registration Rights Agreement between Dynavax Technologies Corporation and Symphony Dynamo Holdings LLC; and

•

the Warrant Purchase Agreement between Dynavax Technologies Corporation and Symphony Dynamo Holdings LLC (the “Warrant Agreement”).

The LLC Agreement provided for the formation of Symphony Dynamo Holdings LLC (“Holdings”) and its wholly-owned subsidiary, SDI. Pursuant to the Funding Agreement, Symphony invested $50 million in Holdings ($20 million at closing and an additional $30 million in April 2007), which was invested into SDI to fund the Development Programs. Pursuant to the License Agreement, we licensed to Holdings our intellectual property rights related to the Development Programs, which were assigned to SDI. Pursuant to the R&D Agreement, which was also assigned to SDI, we are primarily responsible for performing the work required to proceed with the Development Programs unless we determine that certain work should be undertaken by third party contractors retained by SDI. As a result of these agreements, Symphony owns 100% of the equity of Holdings, which owns 100% of the equity of SDI.

Pursuant to the Warrant Agreement, we issued to Holdings a five-year warrant to purchase 2,000,000 shares of our common stock, which Holdings distributed to Symphony, at $7.32 per share, representing a 25% premium over the applicable 60-day trading range average of $5.86 per share. The warrant exercise price is subject to reduction to $5.86 per share if either of two events occurs: (a) we enter into a collaboration agreement with a third party for a specified oncology program; or (b) the Purchase Option (as defined below) is terminated or expires unexercised. The warrant may be exercised or surrendered for a cash payment upon consummation of an all cash merger or acquisition of Dynavax, the obligation for which would be settled by the surviving entity. The warrant, issued upon closing, was assigned a value of $5.6 million using the Black-Scholes valuation model and was recorded in additional paid in capital.

In consideration for the warrant, we received an exclusive purchase option (the “Purchase Option”) to acquire the Development Programs through the purchase of all of the equity in SDI during the five-year term at specified prices that range from $94.9 million as of June 30, 2009, increasing quarterly up to $144.1 million at the end of the five-year term. The Purchase Option exercise price is

payable in cash or a combination of cash and shares of Dynavax common stock, at our sole discretion. We also received an exclusive option to purchase either the hepatitis B or hepatitis C program (the “Program Option”) during the first year of the arrangement. In April 2007, we exercised our Program Option for the hepatitis B program. The exercise of this Program Option triggered a payment obligation of $15 million which will either be (a) due to Symphony upon the expiration of the SDI collaboration in 2011 if the Purchase Option is not exercised; or (b) included as part of the applicable purchase price upon exercise of the Purchase Option. The intellectual property rights to the remaining cancer and hepatitis C therapy programs, if not purchased through the exercise of the Purchase Option, will remain with SDI.

We have determined, pursuant to the guidance in FIN 46R, that SDI is a variable interest entity and we are its primary beneficiary. As a result, the financial position and results of operations of SDI have been included in our consolidated financial statements from the date of formation on April 18, 2006.

At June 30, 2009, the investments held by SDI were $22.8 million. The investments held by SDI in the consolidated balance sheet include the aggregate $50 million of funding, less funds spent on the Development Programs as of the end of each reporting period.

At June 30, 2009, the noncontrolling interest balance was $0.6 million. The noncontrolling interest in SDI in the consolidated balance sheet represents Symphony’s equity investment in SDI of $50 million, reduced by the $5.6 million fair value of the warrants we issued and $2.6 million of fees we paid to Symphony upon the transaction’s closing, and the losses attributed to the noncontrolling interest since its inception in April 2006. The noncontrolling interest was further reduced when we recorded the $15 million liability upon our exercise of the Program Option in April 2007, as that amount will either be (a) due to Symphony upon the expiration of the SDI collaboration in 2011 if the Purchase Option is not exercised; or (b) included as part of the applicable purchase price upon exercise of the Purchase Option.

Net losses incurred by SDI and charged to the noncontrolling interest were $2.0 million and $3.1 million for the six months ended June 30, 2009 and 2008, respectively. In accordance with FAS 160, we have attributed net income or loss to Dynavax and the noncontrolling interest in SDI in our consolidated statements of operations.

6. Financing Agreement

On August 26, 2008, Dynavax and Deerfield Management, a healthcare investment fund, and its affiliates (“Deerfield”) entered into a Settlement Agreement and Mutual General Release (the “Settlement Agreement”) under which the parties agreed to terminate the Loan Agreement dated July 18, 2007 (the “Loan Agreement”) and also to provide for an amendment of the warrants previously issued to Deerfield pursuant to the Loan Agreement. The Settlement Agreement terminated any further obligations under the Loan Agreement.

Under the Loan Agreement, Deerfield agreed to advance to Dynavax loans that could be drawn down over a three-year period in the aggregate principal amount of up to $30 million, subject to achievement of specific milestones in relation to the development of certain products in Dynavax’s allergy franchise. Repayment of a portion of the loans to Deerfield was contingent upon the positive outcome of studies related to TOLAMBA™, Dynavax’s product candidate for the treatment of ragweed allergy. If the TOLAMBA program was discontinued, Dynavax would have had no obligation to repay Deerfield up to $9 million of the funds earmarked for that program; any other remaining outstanding principal was slated to be due in July 2010. Deerfield received an annual 5.9% cash commitment fee as well as milestone-driven payments in the form of warrants issued or issuable at an exercise premium of 20% over the volume weighted average price in the 15-day period prior to achievement of certain milestones.

Under the Loan Agreement, through August 26, 2008 (the date of termination), we had received $7.5 million in cash from Deerfield, which was recorded as a long-term liability in our consolidated balance sheet. Additionally, we paid and recognized as interest expense $1.7 million of commitment fees and we issued to Deerfield warrants to purchase up to 3,550,000 shares of our common stock. The warrants were valued on the issuance date using the Black-Scholes valuation model. The original warrants issued and their related assumptions under the Black-Scholes option valuation model are as follows (in thousands, except for Black-Scholes Assumptions):


		Black-Scholes Assumptions
Warrant Issuance Date	Shares Issued	Risk-Free Interest Rate		Expected Life (in years)	Volatility	Exercise Price per Share		Assigned Value using Black- Scholes
July 18, 2007	1,250	4.9	%	5.5	0.7	$	5.13	$	3,350
October 18, 2007	1,300	4.2	%	5.5	0.7	$	5.75		3,700
December 27, 2007	1,000	3.6	%	5.5	0.7	$	5.65		2,746

Total	3,550							$	9,796

At the date of each issuance, the warrant valuation was recorded as a deferred transaction cost in other assets and an increase in additional paid in capital. The deferred transaction cost was amortized on a straight-line basis and recognized as interest expense through the termination of the Loan Agreement. We amortized $0 and $1.8 million of deferred transaction cost in interest expense for the six months ended June 30, 2009 and 2008, respectively.

Under the Settlement Agreement, $5.0 million of funds received for the TOLAMBA program were forgiven, resulting in loan forgiveness in the statement of operations and a reduction in long-term liabilities as of and for the fiscal year ended December 31, 2008. All commitment fees paid to date, which totaled $1.7 million, were applied to the loan, resulting in a reduction in interest expense and long-term liabilities as of and for the fiscal year ended December 31, 2008. We paid the remaining loan balance of $0.8 million in cash to Deerfield. In addition, the warrants previously issued to Deerfield were amended as follows:


Warrant Issuance Date	Shares Issued (in thousands)	Expiration Date	Exercise Price per Share
July 18, 2007	1,250	2/26/2014	$	5.13
October 18, 2007	1,300	2/26/2014	$	1.68
December 27, 2007	300	2/26/2014	$	5.65
December 27, 2007	700	2/26/2014	$	5.65	⁽¹⁾

Total	3,550

(1)

The warrants to purchase an aggregate of 700,000 shares of our common stock issued on December 27, 2007 were amended to provide for a termination date of February 26, 2014 at the existing exercise price of $5.65; provided that if Dynavax’s average daily volume weighted average price (the “VWAP”) over the 15 trading days prior to August 26, 2009 is below $4.00 per share then such warrants will be amended to provide an exercise price equal to the VWAP over the 15 trading days prior to August 26, 2009.

The amendments to the warrants resulted in a re-measurement of the fair value based on the amended terms and current period assumptions and were accounted for as modifications to equity awards under the provisions of SFAS 123R, “Share-Based Payment.” We recorded interest expense and an increase of additional paid in capital of $0.9 million for the fiscal year ended December 31, 2008 due to these modifications.

7. Commitments and Contingencies

We lease our facilities in Berkeley, California (the “Berkeley Lease”) and Düsseldorf, Germany (the “Düsseldorf Lease”) under operating leases that expire in September 2014 and March 2023, respectively. The Berkeley Lease can be terminated in February 2011 at no cost to us but otherwise extends automatically until September 2014. The Berkeley Lease 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 Berkeley Lease provided 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 consolidated balance sheets as of June 30, 2009 and December 31, 2008. The Berkeley Lease incentive is amortized as an offset to rent expense over the estimated initial lease term, through September 2014. Total net rent expense related to our operating leases was $1.2 million for each of the years ended June 30, 2009 and 2008. Deferred rent was $0.8 million as of June 30, 2009.

We have entered into a sublease agreement under the Berkeley Lease for a certain portion of the leased space with scheduled payments to us totaling $58 thousand in 2009 and $40 thousand in 2010. The sublease rental income is offset against rent expense.

Future minimum payments under the non-cancelable portion of our operating leases at June 30, 2009, excluding payments from the sublease agreement, are as follows (in thousands):


Year ending December 31,
2009 (remaining six months)	$	1,281
2010		2,600
2011		2,657
2012		2,716
2013		2,762
Thereafter		6,914

Total	$	18,930

During the fourth quarter of 2004, we established a letter of credit with Silicon Valley Bank as security for our Berkeley Lease in the amount of $0.4 million. The letter of credit remained outstanding as of June 30, 2009 and is collateralized by a certificate of deposit which has been included in restricted cash in the consolidated balance sheets as of June 30, 2009 and December 31, 2008. Under the terms of the Berkeley Lease, 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 established a letter of credit with Deutsche Bank as security for our Düsseldorf Lease in the amount of $0.3 million. The letter of credit remained outstanding as of June 30, 2009 and is collateralized by a certificate of deposit which has been included in restricted cash in the consolidated balance sheet as of June 30, 2009.

In addition to the non-cancelable commitments included above, we have entered into contractual arrangements that obligate us to make payments to the contractual counterparties upon the occurrence of future events. In the normal course of operations, we have entered into license and other agreements and intend to continue to seek additional rights relating to compounds or technologies in connection with our discovery, manufacturing and development programs. Under the terms of the agreements, we may be required to pay future up-front fees, milestones and royalties on net sales of products originating from the licensed technologies. We consider these potential obligations to be contingent and have summarized all significant arrangements below.

We rely on research institutions, contract research organizations, clinical investigators and clinical material manufacturers. As of June 30, 2009, under the terms of our agreements, we are obligated to make future payments as services are provided of approximately $9.3 million through 2013. These agreements are terminable by us upon written notice. We are generally only liable for actual effort expended by the organizations at any point in time during the contract, subject to certain termination fees and penalties.

Under the terms of our exclusive license agreements with the Regents of the University of California, as amended, for certain technology and related patent rights and materials, we pay annual license or maintenance fees and will be required to pay milestones and royalties on net sales of products originating from the licensed technologies. Under the terms of our license agreements, we could be expected to pay approximately $0.3 million in 2009 related to such fees and milestone payments to the Regents.

8. Collaborative Research and Development Agreements

GlaxoSmithKline

In December 2008, we entered into a worldwide strategic alliance with GlaxoSmithKline (“GSK”) to discover, develop, and commercialize toll-like receptor (“TLR”) inhibitors for diseases such as lupus, psoriasis, and rheumatoid arthritis. We received an initial payment of $10 million and agreed to conduct research and early clinical development in up to four programs and are eligible to receive future potential development and commercialization milestones totaling approximately $200 million per program. GSK can exercise its exclusive option to license each program upon achievement of proof-of-concept or earlier upon certain circumstances. After exercising its option, GSK would carry out further development and commercialization of these products. We are eligible to receive tiered, up to double-digit royalties on sales and have retained an option to co-develop and co-promote one product. Revenue from the initial payment is deferred and is being recognized over the expected period of performance which is estimated to be seven years. For the three and six months ended June 30, 2009, we recognized revenue of $0.4 million and $0.7 million, respectively, related to the initial payment.

AstraZeneca

In September 2006, we entered into a three-year research collaboration and license agreement with AstraZeneca for the discovery and development of TLR9 agonist-based therapies for the treatment of asthma and chronic obstructive pulmonary disease. The collaboration is using our proprietary second-generation TLR9 agonist immunostimulatory sequences (“ISS”). Under the terms of the agreement, we are collaborating with AstraZeneca to identify lead TLR9 agonists and conduct appropriate research phase studies. AstraZeneca is responsible for any development and worldwide commercialization of products arising out of the research program. We have the option to co-promote in the United States products arising from the collaboration. We received an upfront payment of $10 million, and are eligible to receive research funding, preclinical milestone payments, and potential future development milestones of up to $126 million. Upon commercialization, we are also eligible to receive royalties based on product sales.

In September 2008, we received a $4.5 million milestone payment from AstraZeneca for the nomination of the first candidate drug, AZD1419. We are currently working on a second candidate drug, and in February 2009, we extended our research collaboration with AstraZeneca though July 2010 to provide funding for a third candidate drug. Revenue from milestones received during the development plan is deferred and recognized ratably over estimated performance period of the collaboration agreement. For the three and six months ended June 30, 2009, we recognized revenue related to the milestone for the nomination of AZD1419 of $0.4 million and $1.0 million, respectively. Collaboration revenue resulting from the performance of research services amounted to $0.9 million and $1.8 million for the three and six months ended June 30, 2009, respectively. As of June 30, 2009, we had recorded cumulative deferred revenue of $12.0 million associated with the milestone for the nomination of a candidate drug, upfront fee and amounts billed in advance for research services per the contract terms.

National Institutes of Health and Other Funding

In September 2008, we were awarded a five-year $17 million contract to develop our ISS technology using TLR9 agonists as vaccine adjuvants. The contract was awarded by the National Institutes of Health’s (“NIH”) National Institute of Allergy and Infectious Diseases (“NIAID”) to develop novel vaccine adjuvant candidates that signal through receptors of the innate immune system. The contract supports adjuvant development for anthrax as well as other disease models. NIAID is funding 100% of the total $17 million cost of Dynavax’s program under Contract No. HHSN272200800038C. For the three and six months ended June 30, 2009, we recognized revenue of approximately $0.4 million and $0.8 million, respectively.

In July 2008, we were awarded a two-year $1.8 million grant from the NIH to develop a therapy for systemic lupus erythematosus, an autoimmune disease. Revenue associated with this grant is recognized as the related expenses are incurred. For the three and six months ended June 30, 2009, we recognized revenue of approximately $0.3 million and $0.5 million, respectively.

In 2003, we were awarded government grants totaling $8.3 million to fund research and development. Certain of these grants have been extended through the second quarter of 2009. In August 2007, we were awarded a two-year $3.3 million grant to continue development of a novel universal influenza vaccine for controlling seasonal and emerging pandemic flu strains. Revenue associated with these grants is recognized as the related expenses are incurred. For the six months ended June 30, 2009 and 2008, we recognized revenue of approximately $0.7 million and $1.1 million, respectively.

Merck & Co., Inc.

In October 2007, we entered into a global license and development collaboration agreement and a related manufacturing agreement with Merck to jointly develop HEPLISAV, a novel investigational hepatitis B vaccine. Under the terms of the agreement, Merck received worldwide exclusive rights to HEPLISAV, and agreed to fund future vaccine development and be responsible for commercialization. We received a non-refundable upfront payment of $31.5 million. Revenue from the initial payment was deferred and recognized ratably over the estimated performance period of the collaboration agreement.

On December 18, 2008, Merck provided notice of its termination of the collaboration, at which time all development, manufacturing and commercialization rights to HEPLISAV reverted to Dynavax. As a result of Merck’s termination, we accelerated the applicable performance period over which we ratably recognize revenue from the upfront fee through the effective date of the termination in June 2009. For the six months ended June 30, 2009 and 2008, we recognized revenue of $28.5 million and $1.3 million, respectively, related to the upfront fee. Collaboration revenue resulting from the performance of research and development services is recognized as related research and development costs are incurred. Cost reimbursement revenue under this collaboration agreement totaled $0.3 million and $10.5 million for the six months ended June 30, 2009 and 2008, respectively. Merck is obligated to make payments to Dynavax for the 180-day wind down period following Merck's written notice of termination. Merck has disagreed with the amounts for which it may be liable under the agreement and we are currently in negotiations to determine the amount of the wind down payment.

9. Net Income (Loss) Per Share

Basic net income (loss) per share is calculated by dividing the net income (loss) attributable to Dynavax by the weighted-average number of common shares outstanding during the period. Diluted net income (loss) per share is computed by dividing the net income (loss) attributable to Dynavax by the weighted-average number of common shares outstanding during the period and dilutive potential common shares using the treasury-stock method. For purposes of this calculation, common stock subject to repurchase by us, preferred stock, options and warrants are considered to be dilutive potential common shares and are only included in the calculation of diluted net income (loss) per share when their effect is dilutive. Outstanding warrants and stock options to purchase 11.5 million and 11.1 million shares of common stock as of June 30, 2009 and 2008, respectively, were excluded from the calculation of diluted net income (loss) per share for both the three and six months ended June 30, 2009 and 2008 because the effect would have been anti-dilutive.

The following is a reconciliation of the numerator and denominator used in the basic and diluted net income (loss) per share computations (in thousands):


	Three Months Ended June 30,					Six Months Ended June 30,
	2009		2008			2009		2008
Numerator: Net income (loss) attributable to Dynavax	$	4,110	$	(6,079	)	$	9,211	$	(18,508	)
Denominator:
Weighted-average common shares outstanding used for basic net income (loss) per share		39,923		39,806			39,906		39,795
Weighted-average common shares outstanding used for diluted net income (loss) per share		40,064		39,806			39,906		39,795

10. Comprehensive Income (Loss)

Comprehensive income (loss) is comprised of net income (loss) and other comprehensive income or loss. Other comprehensive income or loss includes certain changes in stockholders’ equity not included in net income (loss). Comprehensive income (loss) is as follows (in thousands):


	Six Months Ended June 30,
	2009			2008
Net income (loss) attributable to Dynavax	$	9,211		$	(18,508	)
Decrease in unrealized gain on marketable securities available-for-sale		(48	)		(114	)
Increase in cumulative translation adjustment		54			69

Comprehensive income (loss) attributable to Dynavax	$	9,217		$	(18,553	)

11. Stockholders’ Equity

As of June 30, 2009, we have two share-based compensation plans: the 2004 Stock Incentive Plan, which includes the 2004 Non-Employee Director Option Program; and the 2004 Employee Stock Purchase Plan. The 1997 Equity Incentive Plan, or 1997 Plan, expired in the first quarter of 2007. Upon expiration of the 1997 Plan, 273,188 shares previously available for grant expired. Any outstanding options under the 1997 Plan that are cancelled in future periods will automatically expire and will no longer be available for grant.

Under our stock-based compensation plans, option awards generally vest over a 4-year period contingent upon continuous service and expire 10 years from the date of grant (or earlier upon termination of continuous service). The fair value of each option is estimated on the date of grant using the Black-Scholes option valuation model and the following weighted-average assumptions:


	Employee Stock Options												Employee Stock Purchase Plan
	Three Months Ended June 30,						Six Months Ended June 30,						Six Months Ended June 30,
	2009			2008			2009			2008			2009			2008
Weighted-average fair value per share	$	1.00		$	1.38		$	0.53		$	2.64		$	0.73		$	2.15
Risk-free interest rate		1.6	%		3.0	%		1.7	%		2.8	%		0.8	%		2.0	%
Expected life (in years)		4.0			4.0			4.0			4.4			1.2			1.3
Volatility		1.6			0.8			1.6			0.7			1.6			0.7
Expected dividends		—			—			—			—			—			—

Expected volatility is based on historical volatility of our stock and comparable peer data. The expected life of options granted is estimated based on historical option exercise and employee termination data. Executive level employees, who hold a majority of the options outstanding, and non-executive level employees were grouped and considered separately for valuation purposes. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant.

We recognized the following amounts of stock-based compensation expense (in thousands):


	Three Months Ended June 30,				Six Months Ended June 30,
	2009		2008		2009			2008
Employee and director stock-based compensation expense	$	667	$	775	$	1,189		$	1,418
Other stock-based compensation expense		—		—		(3	)		18

Total	$	667	$	775	$	1,186		$	1,436

The fair value of the options is amortized to expense on a straight-line basis over the vesting periods of the options. Compensation expense recognized was based on awards ultimately expected to vest and reflects estimated forfeitures at an annual rate of 15%. As of June 30, 2009, the total unrecognized compensation cost related to non-vested options granted amounted to $4.8 million, which is expected to be recognized over the options’ remaining weighted-average vesting period of 1.8 years.

Activity under the stock option plans was as follows:


	Options Available for Grant		Number of Options Outstanding		Weighted-Average Exercise Price Per Share
Balance at December 31, 2008	660,653		5,172,976		$	4.79
Options authorized	400,000		—			—
Options granted	(1,134,600	)	1,134,600		$	0.59
Options exercised	—		—			—
1997 Plan shares exercised	—		(2,666	)	$	1.50
Options cancelled:
Options forfeited (unvested).	150,511		(150,511	)	$	4.38
Options expired (vested)	193,090		(193,090	)	$	5.94
1997 Plan options expired	(999	)	—			—

Balance at June 30, 2009	268,655		5,961,309		$	3.96

The following table summarizes outstanding options that are net of expected forfeitures (vested and expected to vest) and options exercisable under our stock option plans as of June 30, 2009:


	Number of Shares	Weighted-Average Exercise Price Per Share		Weighted-Average Remaining Contractual Term (in years)	Aggregate Intrinsic Value
Outstanding options (vested and expected to vest)	5,276,306	$	4.14	7.2	$	558,093
Options exercisable	2,984,493	$	4.97	6.1	$	—

Employee Stock Purchase Plan

As of June 30, 2009, 496,000 shares were reserved and approved for issuance under the Employee Stock Purchase Plan (the “Purchase Plan”), subject to adjustment for a stock split, any future stock dividend or other similar change in our common stock or capital structure. To date, employees acquired 262,072 shares of our common stock under the Purchase Plan. At June 30, 2009, 233,928 shares of our common stock remained available for future purchases.

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 that 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 “Risk Factors” and those that may be identified from time to time in our reports and registration statements filed with the Securities and Exchange Commission.

The following discussion and analysis is intended to provide an investor with a narrative of our financial results and an evaluation of our financial condition and results of operations. This discussion should be read in conjunction with the unaudited 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.

Overview

Our pipeline is comprised of: HEPLISAV, a Phase 3 hepatitis B vaccine; clinical-stage programs for hepatitis C and hepatitis B therapies; and preclinical programs including those partnered with AstraZeneca and GlaxoSmithKline (“GSK”) and our Universal Flu vaccine.

Recent Developments

HEPLISAV

In August 2009, we announced that we had met with the U.S. Food and Drug Administration (FDA) to discuss our plans to resume development of HEPLISAV. We proposed the continued clinical development of HEPLISAV in populations that are less responsive to current licensed hepatitis B vaccines, including adults over 40 years of age, individuals with chronic kidney disease (including end-stage renal disease, or ESRD, patients), individuals infected with HIV or individuals diagnosed with chronic liver disease (including chronic hepatitis C infection). The FDA expressed a general agreement that these populations are appropriate for further clinical development, pending the review of the study protocols and additional supportive information.

We plan to submit this information to the FDA in August 2009 with a goal of having the agency remove the clinical hold in September 2009. The Company is prepared to restart clinical trials in individuals with chronic kidney disease upon removal of the clinical hold.

A subanalysis of results from our Phase 3 PHAST clinical trial demonstrate subjects over 40 years of age receiving two doses of HEPLISAV over one month achieved a seroprotection rate of 92%, compared to 75% of subjects receiving three doses of a licensed vaccine over six months. Over 2,500 individuals have been vaccinated with HEPLISAV to date. Dynavax has worldwide commercial rights to HEPLISAV, which combines hepatitis B surface antigen (HBsAg) with a proprietary Toll-like Receptor 9 agonist to enhance the immune response.

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, 2009 as compared with those disclosed in its Annual Report on Form 10-K for the year ended December 31, 2008, except as discussed below with regards to the Company’s adoption of Statement of Financial Accounting Standards No. 160, “Noncontrolling Interests in Consolidated Financial Statements – an amendment of Accounting Research Bulletin No. 51” (“SFAS 160”) effective January 1, 2009.

•

The noncontrolling interest in SDI has been reclassified to equity.

•

Consolidated net income or loss has been adjusted to include the net income or loss attributed to the noncontrolling interest in SDI.

•

Consolidated comprehensive income or loss has been adjusted to include the comprehensive income or loss attributed to the noncontrolling interest in SDI.

Results of Operations

Revenues

Revenues consist of amounts earned from collaborations, government and private agency grants, and services and license fees. Collaboration revenue includes amounts recognized under our collaboration agreements. Grant revenue includes amounts earned under government and private agency grants. Services and license fees include research and development and contract manufacturing services, license fees and royalty payments.

The following is a summary of our revenues (in thousands, except for percentages):


	Three Months Ended June 30,				Increase (Decrease) from 2008 to 2009					Six Months Ended June 30,				Increase (Decrease) from 2008 to 2009
Revenues:	2009		2008		$			%		2009		2008		$			%
Collaboration revenue	$	14,596	$	7,701	$	6,895		90	%	$	32,288	$	13,475	$	18,813		140	%
Grant revenue		895		1,122		(227	)	(20	%)		2,034		1,446		588		41	%
Services and license revenue		393		1,155		(762	)	(66	%)		906		1,371		(465	)	(34	)%

Total revenues	$	15,884	$	9,978	$	5,906		59	%	$	35,228	$	16,292	$	18,936		116	%

Total revenues for the six months ended June 30, 2009 increased by $18.9 million, or 116%, over the same period in 2008 primarily due to an increase in revenue recognized from our collaboration arrangement with Merck. Collaboration revenue in 2009 includes recognition of $28.5 million of previously deferred revenue associated with the upfront payment from Merck, which was accelerated due to Merck’s termination of the collaboration agreement in December 2008. Grant revenue increased by $0.6 million, or 41%, over the same period in 2008 due primarily to revenues earned from the National Institute of Health (“NIH”) contract we were awarded in September 2008. Services and license revenue of $0.9 million was derived primarily from research and development services provided to customers of Rhein Biotech GmbH (“Rhein” or “Dynavax Europe”).

We anticipate that our revenues in 2009 will exceed 2008 primarily due to our recognition of $28.5 million of deferred revenue associated with the upfront payment from Merck.

Research and Development

Research and development expense consists of compensation and related personnel costs which include benefits, recruitment, travel and supply costs; outside services; allocated facility costs and non-cash stock-based compensation. Outside services relate to our preclinical experiments and clinical trials, regulatory filings, manufacturing our product candidates, and cost of sales relating to service and license revenue.

The following is a summary of our research and development expense (in thousands, except for percentages):


	Three Months Ended June 30,				Increase (Decrease) from 2008 to 2009					Six Months Ended June 30,				Increase (Decrease) from 2008 to 2009
Research and development:	2009		2008		$			%		2009		2008		$			%
Compensation and related personnel costs	$	3,957	$	4,661	$	(704	)	(15	)%	$	8,091	$	10,028	$	(1,937	)	(19	)%
Outside services		3,207		6,071		(2,864	)	(47	)%		7,647		14,107		(6,460	)	(46	)%
Facility costs		1,724		1,824		(100	)	(5	)%		3,465		3,361		104		(3	)%
Non-cash stock-based compensation		349		390		(41	)	(11	)%		367		570		(203	)	(36	)%

Total research and development	$	9,239	$	12,946	$	(3,707	)	(29	)%	$	19,571	$	28,066	$	(8,495	)	(30	)%

Research and development expense for the six months ended June 30, 2009 decreased by $8.5 million, or 30%, compared to the same period in 2008. The decrease in outside services is primarily due to a reduction in clinical development costs associated with HEPLISAV and the discontinuation of development for the TOLAMBA ragweed allergy program in May 2008. The decrease in compensation and related personnel costs is primarily due to the decline in employee headcount to support the organization.

We anticipate that our research and development expense in fiscal 2009 will remain at approximately the same level as 2008, if HEPLISAV development resumes by the fourth quarter of 2009. However, we are currently determining the timing, scope, and funding for future development of HEPLISAV and those amounts are expected to impact future periods.

General and Administrative

General and administrative expense consists primarily of compensation and related personnel costs; outside services such as accounting, consulting, business development, investor relations and insurance; legal costs that include corporate and patent expenses; allocated facility costs and non-cash stock-based compensation.

The following is a summary of our general and administrative expense (in thousands, except percentages):


	Three Months Ended June 30,				Increase (Decrease) from 2008 to 2009					Six Months Ended June 30,				Increase (Decrease) from 2008 to 2009
General and administrative:	2009		2008		$			%		2009		2008		$			%
Compensation and related personnel costs	$	1,591	$	1,800	$	(209	)	(12	)%	$	3,339	$	3,843	$	(504	)	(13	)%
Outside services		851		806		45		6	%		1,975		2,189		(214	)	(10	)%
Legal costs		549		263		286		109	%		1,372		622		750		121	%
Facility costs		232		173		59		34	%		467		483		(16	)	(3	)%
Non-cash stock-based compensation		310		378		(68	)	(18	)%		805		854		(49	)	(6	)%

Total general and administrative	$	3,533	$	3,420	$	113		3	%	$	7,957	$	7,991	$	(34	)	0	%

General and administrative expense for the six months ended June 30, 2009 decreased by $34 thousand compared to the same period in 2008. The decrease in compensation and related personnel costs and outside services is due to an overall decline in the number of administrative employees, consulting fees and other professional fees incurred. These reductions were offset by increases in legal costs related to patent activities.

We expect general and administrative expense to decline in 2009 as compared to 2008, resulting from continued efforts to reduce administrative costs.

Amortization of Intangible Assets

Intangible assets consist of the manufacturing process and customer relationships resulting from our April 2006 acquisition of Rhein and are being amortized over 5 years from the date of acquisition. Amortization of intangible assets was $0.5 million for both the six months ended June 30, 2009 and 2008.

Interest Income, Interest Expense and Other Income (Expense)

Interest income is reported net of amortization of premiums and discounts on marketable securities and realized gains and losses on investments. Interest income was $0.2 million and $1.1 million for the six months ended June 30, 2009 and 2008, respectively. Interest income decreased by $1.0 million, or 86%, compared to the same period in 2008 due to lower investment balances and the decline in returns on our investment portfolio resulting from current market conditions.

Interest expense includes amortization of deferred transaction costs and commitment fees related to the Deerfield financing agreement and miscellaneous banking fees. Interest expense was $27 thousand and $2.7 million for the six months ended June 30, 2009 and 2008, respectively. Interest expense decreased by $2.7 million, or 99%, compared to the same period in 2008 due to interest expense incurred from the commitment fees and warrants issued under the Deerfield financing agreement, which was terminated in August 2008.

Other income (expense) includes gains and losses on foreign currency translation of our activities primarily with Dynavax Europe and gains and losses on disposals of property and equipment. We reported $0.1 million of other expense and $0.2 million of other income for the six months ended June 30, 2009 and 2008, respectively. The variance year over year resulted from the effect of Euro to U.S. Dollar exchange rates.

Losses Attributed to Noncontrolling Interest in Symphony Dynamo, Inc.

Pursuant to the agreements that we entered into with SDI in April 2006, and in accordance with FAS 160, we have attributed net income or loss to Dynavax and the noncontrolling interest in SDI in our consolidated statements of operations. For the six months ended June 30, 2009 and 2008, the losses attributed to the noncontrolling interest were $2.0 million and $3.1 million, respectively.

Recent Accounting Pronouncements

In February 2008, the FASB issued FASB Staff Position (“FSP”) No. FAS 157-2, “Effective Date of FASB Statement No. 157”, which provides a one year deferral of the effective date of SFAS No. 157, Fair Value Measurements (“SFAS 157”) for non-financial assets and non-financial liabilities, except those that are recognized or disclosed in the financial statements at fair value at least annually. Therefore effective January 1, 2009, we implemented SFAS 157 for our nonfinancial assets and liabilities that are remeasured at fair value on a non-recurring basis. The adoption of SFAS 157 for our nonfinancial assets and liabilities that are remeasured at fair value on a non-recurring basis did not impact our financial position or results of operations.

Liquidity and Capital Resources

As of June 30, 2009, we had $53.0 million in cash, cash equivalents and marketable securities and investments held by SDI. Our funds are currently invested in a variety of securities, including institutional money market funds, commercial paper, government and non-government debt securities and corporate obligations.

Cash used in operating activities was $15.4 million during the six months ended June 30, 2009 compared to $23.0 million for the same period in 2008. The decrease in cash usage compared to the prior year was due primarily to our net income as compared to our net loss for the same period in 2008.

Cash provided by investing activities was $11.0 million during the six months ended June 30, 2009 compared to $21.4 million for the same period in 2008. The decrease was attributed to the decline in net proceeds from sales and maturities of marketable securities.

Cash provided by financing activities was $41 thousand during the six months ended June 30, 2009 compared to $2.1 million for the same period in 2008. The decrease was primarily attributed to the termination of the Deerfield financing agreement.

We currently anticipate that our cash and marketable securities, collaboration agreements, and investments held by SDI will enable us to maintain our operations for at least the next twelve months. Because of the significant time it will take for any of our product candidates to complete clinical trials, achieve regulatory approval and generate significant revenue, we will 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.

Additional financing may not be available on acceptable terms, if at all and therefore may adversely affect our ability to operate as a going concern. 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, fail to meet the diligence obligations under existing licenses or enter into collaborative agreements at an earlier stage of development on less favorable terms than we would otherwise choose.

Contractual Obligations

The following summarizes our significant contractual obligations as of June 30, 2009 and the effect those obligations are expected to have on our liquidity and cash flow in future periods (in thousands):


Contractual Obligations:	Total		Less than 1 Year		1-3 Years		4-5 Years		More than 5 years
Future minimum payments under our operating lease, excluding payments from the sublease agreement	$	18,930	$	1,281	$	7,973	$	4,776	$	4,900
Long-term liability from the program option exercised under the SDI collaboration		15,000		—		15,000		—		—

Total	$	33,930	$	1,281	$	22,973	$	4,776	$	4,900

In April 2007, we exercised an option to repurchase our hepatitis B program from SDI. The exercise of the program option triggered a payment obligation of $15 million which will be due upon the expiration of the SDI collaboration in 2011, if the purchase option for all programs is not exercised. The price for the program option is payable in cash only and will be fully creditable against the exercise price for any exercise of the purchase option.

Under the terms of our exclusive license agreements with the Regents of the University of California, as amended, for certain technology and related patent rights and materials, we pay annual license or maintenance fees and will be required to pay milestones and royalties on net sales of products originating from the licensed technologies. As of June 30, 2009, such fees and milestone payments to the Regents could approximate $0.3 million in 2009.

Off-balance Sheet Arrangements

We do not have any off-balance sheet arrangements as defined by rules enacted by the Securities and Exchange Commission (“SEC”) and FASB, and accordingly, no such arrangements are likely to have a current or future effect on our financial position. As described above, SDI is considered a variable interest entity and included in our financial statements. Our financing arrangement with SDI does not qualify as an off-balance sheet arrangement as defined by applicable SEC regulations.

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 currently maintain our portfolio of cash equivalents and investments in a variety of securities, including money market funds, government agency securities and corporate obligations, some of which are government-secured. We do not invest in auction rate securities or securities collateralized by home mortgages, mortgage bank debt, or home equity loans. 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 certain investments outside the U.S. for the operations of Dynavax Europe and have some exposure to foreign exchange rate fluctuations. The cumulative translation adjustment reported in the consolidated balance sheet as of June 30, 2009 was $0.4 million primarily related to translation of Dynavax Europe activities from Euro to U.S. dollars.

ITEM 4.

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, as amended) as of the end of period covered by this report are effective.

(b) Changes in internal controls

There has been no change in our internal controls over financial reporting during our most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal controls over financial reporting.

PART II. OTHER INFORMATION

ITEM 1.

LEGAL PROCEEDINGS

From time to time in the ordinary course of business, we receive claims or allegations regarding various matters, including employment, vendor and other similar situations in the conduct of our operations. We do not believe any of the current claims or allegations are material to our current business or operations.

ITEM 1A.

RISK FACTORS

Various statements in this Quarterly Report on Form 10-Q are forward-looking statements concerning our future products, timing of development activities, 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 significant revenue.

We have experienced significant net losses in each year since our inception. Our accumulated deficit was $239.5 million as of June 30, 2009. To date, our revenue has resulted from collaboration agreements, services and license fees from customers of Dynavax Europe, and government and private agency grants. The grants are subject to annual review based on the achievement of milestones and other factors. Our current grants are scheduled to terminate in 2010, although we were awarded a five-year government contract totaling $17 million in September 2008. We anticipate that we will incur substantial additional net losses for the foreseeable future as the result of our investment in research and development activities.

We do not have any products that generate revenue. The clinical hold on the two U.S. IND Applications for HEPLISAV remains in effect. In a recent meeting with the FDA, we proposed the continued clinical development of HEPLISAV in populations that are less responsive to current licensed hepatitis B vaccines. The FDA expressed a general agreement that these populations are appropriate for further clinical development, pending the review of the study protocols and additional supportive information. We plan to submit this information to the FDA in August 2009 with a goal of having the agency remove the clinical hold in September 2009. However, there can be no assurance whether and when the FDA will remove the clinical hold; whether HEPLISAV can be further developed, financed or commercialized in a timely manner without significant additional studies or patient data or significant expense; and whether any future development will be sufficient to support product approval.

Clinical trials for certain of our other product candidates are ongoing. These and our other product candidates may never be commercialized, and we may never achieve profitability. Our ability to generate revenue depends upon:

•

demonstrating in clinical trials that our product candidates are safe and effective, in particular, in the current and planned trials for our product candidates;

•

obtaining regulatory approvals for our product candidates; and

•

entering into and maintaining successful collaborative relationships.

If we are unable to generate significant revenues or achieve profitability, we may be required to reduce or discontinue our current and planned operations, enter into a transaction that constitutes a change in control of the company, or raise additional capital on less favorable terms.

We will require substantial additional capital and our failure to obtain additional capital when needed could force us to delay, reduce or eliminate our product development programs or future commercialization efforts, or reduce or discontinue operations.

We believe our existing capital resources will be adequate to satisfy our capital needs for at least the next twelve months. In the foreseeable future, we will require substantial additional capital resources in order to continue our operations, and any such funding in the current financing environment may not allow us to continue operations as currently planned. Our future capital requirements are difficult to forecast and will depend on many factors, including:

•

the costs, timing and outcomes of regulatory reviews or other regulatory actions, such as whether and when the FDA will remove the clinical hold and whether we are permitted to further develop HEPLISAV;

•

the scope, progress, duration, results and cost of clinical trials, as well as non-clinical studies and manufacturing-related services for our product candidates;

•

the timing, receipt and amount of milestone and other payments from AstraZeneca, GlaxoSmithKline and potential future collaborators and the extent to which our research and development activities result in the achievement of milestone events under our collaboration agreements;

•

the costs to satisfy our obligations under existing and potential future alliances and collaborations;

•

the extent of our development and manufacturing costs and costs to establish sales and marketing functions for our product candidates that are not subject to our collaborations;

•

the timing, receipt and amount of sales or royalties, if any, from our potential products;

•

our ability to establish strategic alliances, collaborations and licensing or other arrangements on terms favorable to us;

•

the costs of preparing, filing and prosecuting patent applications and maintaining, enforcing and defending intellectual property-related claims; and

•

the extent and scope of our general and administrative expenses.

Our plans provide for us to continue, either alone or with a collaborator, to advance our product candidates through the development process. We do not expect our existing capital resources to be sufficient to enable us to fund the completion of the development of any of our product candidates. We believe our existing capital resources will be adequate to satisfy our capital needs for at least the next twelve months. However, our operating plan may change as a result of many factors, including those described above, and we may need additional funds sooner than planned to meet operational needs and capital requirements for product development and commercialization. We may seek additional capital through a combination of public and private equity offerings and collaborative, strategic alliance and licensing arrangements. If we raise additional capital through the sale of our common stock, existing stockholders may experience dilution of their current level of ownership of our common stock and the terms of the financing may adversely affect the holdings or rights of our stockholders. Our ability to raise funds in the foreseeable future may be adversely impacted by recent deterioration in the U.S. and global financial markets, and additional funds may not be available when we need them on terms that are acceptable to us, or at all. If adequate funds are not available on a timely basis, we may:

•

terminate, delay or downsize clinical trials or manufacturing or other development activities for one or more of our product candidates;

•

delay our establishment of sales and marketing capabilities or other activities that may be necessary to commercialize our product candidates; or

•

curtail significant drug development programs that are designed to identify new product candidates.

The success of our product candidates depends on achieving successful clinical results and regulatory approval. Failure to obtain regulatory approvals could require us to discontinue operations.

None of our product candidates have been approved for sale. Any product candidate we develop is subject to extensive regulation by federal, state and local governmental authorities in the United States, including the FDA, and by foreign regulatory agencies. Our success is primarily dependent on our ability to obtain regulatory approval for our most advanced product candidates. Approval processes in the United States and in other countries are uncertain, take many years and require the expenditure of substantial resources. The clinical hold on the two U.S. IND Applications for HEPLISAV remains in effect, pending the review of the study protocols and additional supportive information. Although we have received recent input from the FDA on the further clinical development of HEPLISAV, there can be no assurance whether and when the FDA will remove the clinical hold; whether HEPLISAV can be further developed, financed or commercialized in a timely manner without significant additional studies, difficulties or delays, or significant expense; and whether any future development will be sufficient to support product approval.

We will need to demonstrate in clinical trials that a product candidate is safe and effective before we can obtain the necessary approvals from the FDA and foreign regulatory agencies. If we identify any safety issues associated with our product candidates, we may be restricted from initiating further trials for those products. Moreover, we may not see sufficient signs of efficacy in those studies. The FDA or foreign regulatory agencies may require us to conduct additional clinical trials prior to approval. Despite the time and money expended, regulatory approvals are uncertain. Failure to successfully complete clinical trials and show that our products are safe and effective would have a material adverse effect on our business and results of operations.

Our clinical trials may be extended, 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 extend, 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, concerns regarding health risks to test subjects or inadequate supply of the product candidate. Even a small delay in a trial for any product candidate could require us to delay commencement of the trial until the target population is available for testing, which could result in a delay of a year or more.

Our registration and commercial timelines depend on results of the current and planned clinical trials and further discussions with the FDA. Any extension, suspension, termination or unanticipated delays of our clinical trials could:

•

adversely affect our ability to timely and successfully commercialize or market these product candidates;

•

result in significant additional costs;

•

potentially diminish any competitive advantages for those products;

•

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; or

•

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.

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 based on data from subsequent studies or long-term use. As a result, limitations on labeling indications or marketing claims, or withdrawal from the market may be required if problems occur after commercialization.

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 most advanced product candidate 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 most advanced product candidate in clinical trials is based on our 1018 ISS compound, and most 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. For example, since March 2008, the two IND Applications for HEPLISAV have been and remain on clinical hold following a SAE that occurred in the PHAST clinical trial. As most of our clinical product candidates contain ISS, a common safety risk across therapeutic areas may hinder our ability to enter into potential collaborations and if adverse safety data are found to apply to our ISS-based technology as a whole, we may be required to significantly reduce or discontinue our operations.

We rely on third parties and our facility in Düsseldorf, Germany to supply materials necessary to manufacture our clinical product candidates for our clinical trials. Loss of these suppliers or key employees in Düsseldorf, or failure to timely replace them may delay our clinical trials and research and development efforts and may result in additional costs, delays or significantly higher costs in manufacturing our product candidates.

We rely on a number of third parties and our facility in Düsseldorf for the multiple steps involved in the manufacturing process of our product candidates, including, for example, ISS, a key component material that is necessary for our product candidates, the production of certain antigens, the combination of the antigens and ISS, and the fill and finish. Termination or interruption of these relationships may occur due to circumstances that are outside of our control, resulting in higher cost or delays in our product development efforts.

We and these third parties are required to comply with applicable FDA current good manufacturing practice regulations and other international regulatory requirements. If one of these parties fails to maintain compliance with these regulations, the production of our product candidates could be interrupted, resulting in delays and additional costs. Additionally, these third parties and our manufacturing facility must undergo a pre-approval inspection before we can obtain marketing authorization for any of our product candidates.

We have relied on a single supplier to produce our ISS for clinical trials. 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 internal ISS manufacturing capability which would result in increased capital and operating costs and delays in developing and 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.

We currently utilize our facility in Düsseldorf to manufacture the hepatitis B surface antigen for HEPLISAV. The clinical hold on the two U.S. IND Applications for HEPLISAV has remained in effect since March 2008. There can be no assurance as to whether HEPLISAV can be further developed. Moreover, if HEPLISAV cannot be successfully developed, we will have to use the Düsseldorf facility for alternative manufacturing or research activities that may not fully utilize the facility’s capacity, resulting in continued operating costs that may not be offset by corresponding revenues. We may consider other alternatives for the Düsseldorf facility, including its sale or closure which would result in certain costs to discontinue operations.

We rely on contract research organizations to conduct our clinical trials. If these third parties do not fulfill 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 our product candidates.

We rely on third parties to conduct our clinical trials. If these third parties do not perform their obligations or meet expected deadlines our planned clinical trials may be extended, delayed or terminated. Any extension, delay or termination of our clinical trials would delay our ability to commercialize our products and could have a material adverse effect on our business and operations.

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.

Even if we obtain regulatory approval for our product candidates and are able to commercialize them, our products may not gain market acceptance among physicians, patients, health care payors and the medical community.

The degree of market acceptance of any of our approved products will depend upon a number of factors, including:

•

the indication for which the product is approved and its approved labeling;

•

the presence of other competing approved therapies;

•

the potential advantages of the product over existing and future treatment methods;

•

the relative convenience and ease of administration of the product;

•

the strength of our sales, marketing and distribution support;

•

the price and cost-effectiveness of the product; and

•

sufficient third-party reimbursement.

The FDA or other regulatory agencies could limit the labeling indication for which our product candidates may be marketed or could otherwise limit marketing efforts for our products. If we are unable to successfully market any approved product candidates, or marketing efforts are restricted by regulatory limits, our ability to generate revenues could be significantly impaired.

A key part of our business strategy is to establish collaborative relationships to commercialize and fund development of our product candidates. We may not succeed in establishing and maintaining collaborative relationships, which may significantly limit our ability to develop and commercialize our products successfully, if at all.

We will need to establish collaborative relationships to obtain domestic and international sales, marketing and distribution capabilities for our product candidates, in particular with respect to the commercialization of HEPLISAV. We also may enter into collaborative relationships to provide funding to support our research and development programs. The process of establishing and maintaining collaborative relationships is difficult, time-consuming and involves significant uncertainty, including:

•

our partners 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;

•

our contracts for collaborative arrangements may expire;

•

our partners may choose to pursue alternative technologies, including those of our competitors;

•

we may have disputes with a partner that could lead to litigation or arbitration;

•

we do not have day to day control over the activities of our partners and have limited control over their decisions;

•

our ability to generate future event payments and royalties from our partners depends upon their abilities to establish the safety and efficacy of our drug candidates, obtain regulatory approvals and achieve market acceptance of products developed from our drug candidates;

•

we or our partners may fail to properly initiate, maintain or defend our intellectual property rights, where applicable, or a party may utilize our proprietary information in such a way as to invite litigation that could jeopardize or potentially invalidate our proprietary information or expose us to potential liability;

•

our partners may not devote sufficient capital or resources towards our product candidates; and

•

our partners may not comply with applicable government regulatory requirements.

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 or to successfully transition terminated collaborative agreements, 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 capital.

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 pharmaceutical companies, biotechnology companies, academic institutions and research organizations, in developing therapies to treat or prevent infectious diseases, allergy, 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.

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 successfully, we may not be able to obtain financing, enter into collaborative arrangements, 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, including our Chief Executive Officer, Dr. Dino Dina. 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 key personnel, our research and product development goals, including the identification and establishment of key collaborations, operations and marketing efforts could be delayed or curtailed.

We may develop, seek regulatory approval for and market our product candidates outside the United States, requiring a significant commitment of resources. Failure to successfully manage our international operations could result in significant unanticipated costs and delays in regulatory approval or commercialization of our product candidates.

We may introduce certain of our product candidates in various markets outside the United States. Developing, seeking regulatory approval for and marketing our product candidates outside the United States could impose substantial burdens on our resources and divert management’s attention from domestic operations. 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, laws and treaties;

•

securing international distribution, marketing and sales capabilities;

•

adequate protection of our intellectual property rights;

•

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

•

regional and geopolitical risks.

To date, we have not filed for marketing approval for any of our product candidates outside the United States. We may not obtain foreign regulatory approvals on a timely basis, if at all. Approval by the FDA does not ensure approval by regulatory agencies in other foreign countries. However, a failure or delay in obtaining regulatory approval in one jurisdiction may have a negative effect on the regulatory approval process in other jurisdictions, including approval by the FDA. 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 product candidates, which would impair our ability to generate revenues.

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 current research and development efforts depend upon our license arrangements with the Regents of the University of California, or UC. Our dependence on these licenses subjects us to numerous risks, such as disputes regarding the creation or use of intellectual property by us and UC, or scientific collaborators. Additionally, our agreements with UC generally contain diligence or milestone-based termination provisions. Our failure to meet any obligations pursuant to these provisions could allow UC to terminate our agreements or convert exclusive to non-exclusive licenses. In addition, our license agreements with UC 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.

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 or commercialization of our product candidates.

We may be exposed to future litigation by third parties based on claims that our product candidates or proprietary technologies 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 our or another party’s proprietary rights, including a challenge as to the validity of our issued and pending claims. We are involved in various interference and other administrative proceedings related to our intellectual property which has caused us to incur certain legal expenses. If we become involved in any litigation and/or other significant interference proceedings related to our intellectual property or the intellectual property of others, we will incur substantial additional expenses and it will divert the efforts of our technical and management personnel.

Two of our potential competitors, Merck and GSK, are exclusive licensees of broad patents covering hepatitis B surface antigen, a component of HEPLISAV. In addition, the Institute Pasteur also owns or has exclusive licenses to patents covering hepatitis B surface antigen. While some of these patents have expired or will soon expire outside the United States, they remain in force in the United States. To the extent we are able to commercialize HEPLISAV in the United States while these patents remain in force, Merck and/or GSK or the Institute Pasteur may bring claims against us.

If we or our collaborators are unsuccessful in defending or prosecuting our issued and pending claims or in defending potential claims against our products, for example, as may arise in the commercialization of HEPLISAV or any similar product candidate in the United States, we or our collaborator could be required to pay substantial damages or be unable to commercialize our product candidates or use our proprietary technologies without a license from such third party. A license may require the payment of substantial fees or royalties, require a grant of a cross-license to our technology or may not be available on acceptable terms, if at all. 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 could require us to change our business strategy and could materially impact our business and operations.

One of our potential competitors, Pfizer, has issued U.S. patent claims, as well as patent claims pending with the U.S. Patent and Trademark Office, or PTO, that may be asserted against our ISS products. We may need to obtain a license to one or more of these patent claims held by Pfizer by paying fees or royalties or offering rights to our own proprietary technologies in order to commercialize one or more of our formulations of ISS in the U.S. other than with respect to HEPLISAV. Such a license may not be available to us on acceptable terms, if at all, which could preclude or limit our ability to commercialize our products.

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 United States and foreign patent applications. However, in certain cases such protection may be limited, depending in part on existing patents held by third parties, which may only allow us to obtain relatively narrow patent protection. In the United States, 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 United States is even more uncertain. We may be particularly affected by this uncertainty since several of our product candidates may initially address market opportunities outside the United States, where we may only be able to obtain limited patent protection.

The risks and uncertainties that we face with respect to our patents and other proprietary rights include the following:

•

we may not receive an issued patent for any of our patent applications or for any patent applications that we have exclusively licensed;

•

the pending patent applications we have filed or to which we have exclusive rights may take longer than we expect to result in issued patents;

•

the claims of any patents that are issued may not provide meaningful protection 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 parties may limit our intellectual property protection or harm our ability to do business;

•

other parties may independently develop similar or alternative technologies or duplicate our technologies and commercialize discoveries that we attempt to patent; and

•

other parties 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 disclosure of confidential data in 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.

We have licensed some of our development and commercialization rights to certain of our development programs in connection with our Symphony Dynamo funding arrangement and will not receive any future royalties or revenues with respect to this intellectual property unless we exercise an option to repurchase some or all of the programs in the future. We may not obtain sufficient clinical data in order to determine whether we should exercise our option prior to the expiration of the development period, and even if we decide to exercise, we may not have the financial resources to exercise our option in a timely manner.

In April 2006, we granted an exclusive license to the intellectual property for certain ISS compounds for cancer, hepatitis B and hepatitis C therapies (the “Development Programs”) to Symphony Dynamo, Inc. (“SDI”) in consideration for a commitment from Symphony Capital Partners, LP and certain of its affiliates (“Symphony”) to provide $50 million of capital to advance the Development Programs. As part of the arrangement, we received an exclusive purchase option (the “Purchase Option”) to acquire all of the Development Programs through the purchase of all of the equity in SDI during the five-year term at specified prices ranging from $94.9 million as of June 30, 2009, increasing quarterly up to $144.1 million at the end of the five-year term. The Purchase Option exercise price is payable in cash or a combination of cash and shares of Dynavax common stock, at our sole discretion. We also received an exclusive option to purchase either the hepatitis B or hepatitis C program (the “Program Option”) during the first year of the arrangement. In April 2007, we exercised our Program Option for the hepatitis B program. The exercise of this Program Option triggered a payment obligation of $15 million which will either be (a) due to Symphony upon the expiration of the SDI collaboration in 2011 if the Purchase Option is not exercised; or (b) included as part of the applicable purchase price upon exercise of the Purchase Option. The intellectual property rights to the remaining cancer and hepatitis C therapy programs not purchased through the exercise of the Purchase Option will remain with SDI.

We and SDI jointly manage the Development Programs and there can be no assurance that we will agree on various decisions that will enable us to successfully develop the potential products, or even if we are in agreement on the development plans, that the development efforts will result in sufficient clinical data to make a fully informed decision with respect to the exercise of our Purchase Option. If we do not exercise the Purchase Option prior to its expiration, then our rights in and with respect to the Development Programs will terminate and we will no longer have rights to any of the programs licensed to SDI under the arrangement.

If we elect to exercise the Purchase Option, we will be required to make a payment of at least $100.7 million as of September 30, 2009, increasing thereafter quarterly, which at our discretion may be paid partially in shares of our common stock. As a result, in order to exercise the Purchase Option, we will be required to make a substantial payment of cash and possibly issue a substantial number of shares of our common stock. We do not currently have the resources to exercise the Purchase Option and we may be required to enter into a financing arrangement or license arrangement with one or more third parties, or some combination of these in order to exercise the Purchase Option, even if we paid a portion of the purchase price with our common stock. There can be no assurance that any financing or licensing arrangement will be available or even if available, that the terms would be favorable to us and our stockholders.

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.

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 achieve profitability will depend in part on the negotiation of a favorable price or the availability of appropriate reimbursement from third party payors, in particular for HEPLISAV where existing products are approved for our target indications. 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, and pricing and reimbursement decisions may not allow our products to compete effectively with existing or competitive products. 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 our considerable investment in product development. Adequate third-party reimbursement may not be available to enable us to maintain price levels sufficient to achieve profitability and could harm our future prospects and reduce our stock price.

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.

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 or regulatory efforts, in particular any announcements regarding the progress or results of our planned trials and communications from the FDA or other regulatory agencies;

•

our ability to establish and maintain collaborations for the development and commercialization of our product candidates;

•

our ability to raise additional capital to fund our operations;

•

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;

•

maintenance of our existing exclusive licensing agreements with the Regents of the University of California;

•

changes in government regulations, general economic conditions, industry announcements;

•

issuance of new or changed securities analysts’ reports or recommendations;

•

actual or anticipated fluctuations in our quarterly financial and operating results;

•

our ability to maintain continued listing on the Nasdaq markets or similar exchanges; and

•

volume of trading in our common stock.

One or more of these factors could cause a substantial decline in the price of our common stock. In October 2008, we experienced a decline in our market capitalization of nearly 80% based on the FDA’s communication to us regarding the continuation of a clinical hold on two U.S. IND Applications for HEPLISAV. In November 2008, we transferred our listing of Dynavax shares to The Nasdaq Capital Market from The Nasdaq Global Market. We may be delisted from the Nasdaq Capital Market if our share price or market value of publicly held shares does not meet certain thresholds. In addition, securities class action litigation has often been brought against a company following a decline in the market price of its securities. This risk may be particularly relevant for us because we have experienced greater than average stock price volatility, as have other biotechnology companies in recent years. We may in the future be the target of similar litigation. Securities litigation could result in substantial costs, and divert management’s attention and resources, which could harm our business, operating results and financial condition.

The anti-takeover provisions of our certificate of incorporation, bylaws, Delaware law and our share purchase rights plan 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;

•

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.

Our share purchase rights plan may have certain anti-takeover effects. Specifically, the rights issued pursuant to the plan will cause substantial dilution to a person or group that attempts to acquire the Company on terms not approved by the Company’s Board of Directors. Although the rights should not interfere with any merger or other business combination approved by the Board of Directors since the rights issued may be amended to permit such acquisition or redeemed by the Company at $0.001 per right prior to the earliest of (i) the time that a person or group has acquired beneficial ownership of 20% or more of the Common Shares or (ii) the final expiration date of the rights, the effect of the rights plan may deter a potential acquisition of the Company. In addition, we remain 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 three years unless the holder’s acquisition of our stock was approved in advance by our Board of Directors.

We will continue to implement additional financial and accounting systems, procedures or controls as our business and organization changes and to satisfy new reporting requirements.

We are required to comply with the Sarbanes-Oxley Act of 2002 and the related rules and regulations of the SEC. Compliance with Section 404 of the Sarbanes-Oxley Act of 2002, or Section 404, and other requirements may increase our costs and require additional management resources. We may need to continue to implement additional finance and accounting systems, procedures and controls in order to accommodate changes in our business and organization and to comply with new reporting requirements. There can be no assurance that we will be able to maintain a favorable assessment as to the adequacy of our internal control over financial reporting. If we are unable to reach an unqualified assessment, or our independent auditors are unable to issue an unqualified attestation as to the effectiveness of our internal controls over financial reporting, investors could lose confidence in the reliability of our financial reporting which could harm our business and could impact the price of our common stock.

between DYNAVAX TECHNOLOGIES CORPORATION

and THE REGENTS OF THE UNIVERSITY OF CALIFORNIA for

“Method, Compositions and Devices for Administration of Naked Nucleotides Which

Express Biologically Active Peptides

and

Immunostimulatory Oligonucleotide Conjugates”

This amendment (“4^th Amendment”) is made by and between Dynavax Technologies. Corporation, a Delaware corporation having an address at 2929 7^th Street, Suite 100, Berkeley, CA 94710 (“Licensee”) and The Regents of the University of California, a California corporation having its statewide administrative offices at 1111 Franklin Street, Oakland, California 94607-5200 (“The Regents”), represented by its San Diego campus having an address at University of California, San Diego, Technology Transfer Office, Mail-code 0910, 9500 Gilman Drive, La Jolla, California 92093-0910 (“UCSD”) to a certain existing license agreement between the two parties.
