GRANT OF RIGHTS

4.1 Options.

4.1.1 Grant. Dynavax hereby grants to GSK the exclusive option, exercisable on a Dynavax Program-by-Dynavax Program basis at GSK’s sole discretion, to obtain the exclusive license set forth in Section 4.2.1 (each, an “Option”), subject to the terms and conditions described in Sections 4.1.2 - 4.1.6 below. GSK shall be limited to exercising one Option per Dynavax Program, and on exercise of an Option and

-24-

payment of the applicable Option exercise fee, GSK shall have rights to such Dynavax Program consisting of all Compounds under a given Dynavax Program. For the purposes of this Section 4.1, the [ * ] and the [ * ] shall be considered distinct Dynavax Programs, each subject to a separate Option.

4.1.2 [ * ] Period. For the two (2) Dynavax Programs other than [ * ], the Parties will determine whether GSK may exercise the Option [ * ] after a Phase I Ready Compound has completed the [ * ] Proof of Concept Study, as applicable, as follows. Within [ * ] after the JSC determines that a Compound has reached the Phase I Ready stage pursuant to Section 2.7.2(a), the Parties shall [ * ] or Dynavax shall [ * ], as applicable. If the Parties do not agree within such [ * ] period, or if the Parties do agree that [ * ], as applicable, then Dynavax shall continue to progress the Dynavax Program, and the Option for such Dynavax Program may be exercised only following completion of [ * ] the Proof of Concept Study, as applicable; provided, however, that if in GSK’s reasonable judgment as specified in a reasonably detailed written notice to Dynavax delivered within [ * ] after attainment of the Phase I Ready stage, Dynavax does not [ * ], as applicable, then GSK [ * ]. For clarity, GSK may exercise the Option with respect to the TLR 7/9 Program under any of the following circumstances, at the sole discretion of GSK, but in any event [ * ]: (i) after completion of the [ * ] or Proof of Concept Study, as determined pursuant to Section 2.6.3, or (ii) pursuant to Section 4.1.3(b) or 4.1.3(c).

4.1.3 Exercise.

(a) The “Option Period Start” with respect to a Dynavax Program will commence upon the receipt by GSK of written notice from Dynavax of the complete PoC Study Report, complete [ * ] Study Report, or [ * ], as the case may be, as well as access to GSK to the Dynavax data room containing the complete set of material or relevant clinical and preclinical information related to the applicable Dynavax Program. GSK shall decide whether or not to exercise the Option and may exercise the Option with respect to a Dynavax Program by written notice to Dynavax at any time within [ * ] after the Option Period Start, unless extended pursuant to Section 4.1.5 or otherwise extended by the mutual written agreement of the Parties. Upon GSK’s exercise of an Option and receipt by Dynavax of the applicable Option exercise fee set forth in Section 6.2.1(a) or 6.2.2(a) pursuant to the procedure set forth in Section 6.7, the Dynavax Program will become a GSK Development Program. Subject to Section 5.3.2, any Option exercise shall be irrevocable. GSK shall have the right, at any time after exercising the Option with respect to a Dynavax Program and at its sole discretion, to [ * ] from the same Dynavax Program.

-25-

(b) In addition, in the event that either (i) a [ * ], or (ii) a [ * ] occurs (as defined below), GSK shall have the right to exercise its Options to any and all Dynavax Programs, and to terminate Dynavax’s [ * ] rights to participate in the JSC and related Subcommittees, at GSK’s sole discretion, by providing written notice to Dynavax within [ * ] of (A) the event described in (i) above; or (B) the event described in (ii) above, provided that within [ * ] Business Days after Dynavax notifies GSK pursuant to Section 10.2.9, Dynavax shall provide to GSK a written plan for [ * ] and the Parties shall meet to discuss such plan, and if such plan is not reasonably acceptable to GSK (as reasonably detailed in written notice to Dynavax) then a [ * ] shall have occurred. Upon the exercise by GSK of its Option to a Dynavax Program pursuant to this Section 4.1.3(b), the Option exercise fee and the applicable milestone payments and royalty payments due under Article 6 shall all be [ * ] as follows on a Program-by-Program basis for each Program with respect to which GSK exercises its Option:

(1) if Option exercise occurs for a Dynavax Program with a lead Compound (other than the [ * ]) that has not yet satisfied the Pre-Candidate Selection Criteria, then the Option exercise fee and the milestone and royalty payments shall be [ * ];

(2) if Option exercise occurs for a Dynavax Program with a lead Compound that has satisfied the Pre-Candidate Selection Criteria but is prior to the Phase I Ready stage, then the Option exercise fee and the milestone payments and the royalty payments either (i) shall be [ * ], for a Program other than [ * ], or (ii) shall be [ * ].

(3) if Option exercise occurs for a Dynavax Program with a lead Compound at the Phase I Ready stage, but prior to initiation of a Phase 2 Clinical Trial, then the Option exercise fee and the milestone payments and royalty payments shall all be [ * ] from the payments that would have been payable under Article 6 had GSK exercised its Option after completion of the Proof of Concept Study;

(4) if Option exercise occurs for a Dynavax Program after the initiation of a Phase 2 Clinical Trial for such Program, then the Option exercise fee and the milestone payments and royalty payments shall be [ * ] that would have been payable under Article 6 had GSK exercised its Option after the Proof of Concept Study; and

(5) if Option exercise occurs for a Dynavax Program pursuant to Section 4.1.3(b)(ii) wherein Dynavax has [ * ] (i) within [ * ] of the Effective Date of this Agreement, then, [ * ] above of this Section 4.1.3(b), in the total amount of [ * ], and, if such Option exercise occurs (ii) more than [ * ] after the Effective Date but prior to [ * ] after the Effective Date of this Agreement, then, [ * ] above of this Section 4.1.3(b), in the total amount of [ * ].

The respective obligations of the Parties with respect to exclusivity under Article 7 shall remain unchanged.

(c) In the event that a [ * ], then within [ * ] after the [ * ], and quarterly thereafter, the Parties and the acquiror shall meet to discuss, in good faith and in as much detail and specifics as is practicable at the time, [ * ] under this Agreement. If at any time in the [ * ] following the [ * ], GSK has a reasonable, good faith basis to believe, based on the plans, documents, actions or inactions of Dynavax [ * ] that Dynavax [ * ] has not or will not, with respect to any Program, employ diligent efforts or human and material resources that are at least equivalent to the diligent efforts and human and material

-26-

resources that were employed by Dynavax for the Program prior to (and without any allowance for) any delay, disruption or de-prioritization of such Program as a result of or in contemplation of such [ * ], then GSK shall provide written notice to Dynavax [ * ], such notice to allege the specific basis for GSK’s view that the diligent efforts or human and material resources being applied or to be applied to the Program in question are or are expected to be less than those that were applied to the Program by Dynavax [ * ]. Dynavax [ * ] shall notify GSK whether or not it plans to cure such deficiency, and if it so elects to cure, shall have a [ * ] to cure any such deficiencies in efforts or resources so alleged by GSK. In the event that Dynavax [ * ] notifies GSK that it does not intend to cure such deficiencies or GSK reasonably believes that such deficiency has not been corrected or cured within such [ * ], GSK shall have the right to exercise its Options to any and all Dynavax Programs, and to terminate Dynavax’s [ * ] rights to participate in the JSC and related Subcommittees, at GSK’s sole discretion, by providing written notice to Dynavax within thirty (30) days after such [ * ] or such notice from Dynavax [ * ]. Upon the exercise by GSK of its Option to a Dynavax Program pursuant to this Section 4.1.3(c), the Option exercise fee and the applicable milestone payments and royalty payments due under Article 6 shall all be [ * ] as set forth in Section 4.1.3(b)(1)-(5) as applicable, on a Program-by-Program basis for each Program with respect to which GSK exercises its Option.

4.1.4 Expiration or Termination of Option. If GSK does not exercise the Option with respect to a particular Dynavax Program within the applicable [ * ] or GSK elects not to exercise the Option, then, subject to Section 4.1.5, the Option shall terminate with respect to such Dynavax Program, which shall become a Dynavax Development Program, and Dynavax will thereafter have all rights, itself or with or through an Affiliate or Third Party, (a) to Develop and commercialize all Compounds within the Dynavax Program, subject to any applicable royalty payments set forth in Section 6.5, and (b) to use any data, regulatory filings and know-how generated or used in the course of the Dynavax Program, to the extent such [ * ] that are included in the Dynavax Development Program.

4.1.5 HSR and Equivalent Foreign Laws. If GSK reasonably determines in good faith prior to the expiration of the applicable period for exercise of an Option for a particular Dynavax Program (the “Option Deadline Period”) that the exercise of such Option is required to be filed with the Federal Trade Commission (the “FTC”) under the Xxxx-Xxxxx-Xxxxxx Antitrust Improvements Act of 1976 (15 U.S.C. §18a) (“HSR”) or with equivalent foreign governmental authorities under any similar foreign law, GSK shall provide written notice of exercise of the Option to Dynavax prior to the end of the Option Deadline Period, which notice shall include GSK’s binding commitment to complete the exercise of the Option, subject only to HSR or other governmental clearance by the FTC or other governmental authority, and the Option Deadline Period automatically shall be extended for [ * ] (the “Option Deadline Extension Period”). If the exercise of the Option does not comply with the requirements of Section 4.1 and this Section 4.1.5, including, for example, because it includes other conditions to the completion of the exercise of the Option other than the grant of HSR or other governmental clearance, then the Parties shall negotiate in good faith to determine an appropriate way to proceed. If HSR or other governmental clearance is not granted within the Option Deadline Extension Period, or if GSK receives a “Second Request” from the FTC or similar request for additional information from a governmental authority in connection with such filing, the Option Deadline Extension Period shall be extended for an additional period of time (not to exceed an additional [ * ]) to permit GSK to obtain FTC or other governmental clearance or to respond to the Second Request or provide additional information to the governmental authority. If GSK elects not to respond to the Second Request or to withdraw its request for HSR or other governmental clearance or HSR, the Option shall terminate, and Dynavax shall have the same rights as are set forth in Section 4.1.4 in respect of the Compounds resulting from the applicable Dynavax Program. If

-27-

HSR or other governmental clearance has not been granted by the end of the extended Option Deadline Extension Period, Dynavax and GSK shall promptly meet to discuss in good faith whether an additional extension of the Option Deadline Extension Period is reasonable under the circumstances, and to discuss and consider in good faith, where appropriate, the [ * ], with the objective of placing each Party[ * ] if the Program in question had not been included in the Agreement from the beginning as of the Effective Date. Notwithstanding the foregoing, nothing in this paragraph or the Agreement shall require either Party to divest any assets or to take action (beyond cooperation with the other Party) to respond to any Second Request.

4.1.6 Tolling of Payment Obligations. If the exercise by GSK of any Option under Section 4.1 requires the making of filings under HSR, or under any similar premerger notification provision in the European Union or any other jurisdiction, then all rights and obligations related to the exercise of such Option (including payment of any Option exercise fee or other milestone) shall be tolled until the applicable waiting period has expired or been terminated or until approval or clearance from the reviewing authority has been received, and each Party agrees to cooperate at the request of the Party which decides in its sole discretion to respond to any such request for information to expedite review of such transaction. In the event that HSR clearance is not reasonably achievable within [ * ] days from notification, the Parties shall discuss in good faith potential alternatives, including, without limitation, termination of the relevant Program or the Agreement, as may be mutually agreed between the Parties in good faith, and, where appropriate, to discuss and consider in good faith the renegotiation of their financial and other obligations under the Agreement with respect to the affected Program.

4.2 License Grants.

4.2.1 License to GSK. Subject to the terms and conditions of this Agreement and upon GSK’s exercise of the relevant Option in accordance with Section 4.1 and Dynavax’s receipt of the applicable Option exercise fee, Dynavax and its Affiliates shall be hereby deemed to have granted and hereby grant to GSK the exclusive right and license (even as to Dynavax and its Affiliates, except for the limited purpose of conducting Research and Development activities with respect to Back-up Compounds or formulations as expressly contemplated under Section 5.2) in the Territory, with the right to grant sublicenses, under all of Dynavax’s and its Affiliates’ right, title and interest in and to the Exclusively Licensed IP to make, have made, use, sell, offer for sale and import Compounds under such Dynavax Program as and into GSK Products in the Field during the Term.

4.2.2 No Grant of Rights to Third Parties. Until such time as the Option Deadline Period, including any Option Deadline Extension Period (as may be extended), for an Option granted to GSK pursuant to Section 4.1 with respect to a given Dynavax Program has expired or terminated (including, for example, because [ * ] terminated a Dynavax Program), Dynavax and its Affiliates shall not grant to any Third Party rights to any Exclusively Licensed IP that are inconsistent with or that would interfere with the grant of the licenses that may result from the exercise of such Option by GSK hereunder. For the avoidance of doubt, the Parties understand and agree that for so long as an Option is in effect, such Option shall be exclusive as to the Compounds that are the subject of the relevant Dynavax Program, and Dynavax and its Affiliates shall have no right to offer or negotiate with any Third Party with respect to the grant to such Third Party of any right or license, or with respect to any settlement, consent judgment or other disposition of any action or proceeding under Article 8, or with respect to any other encumbrance of any kind, in or to any of such Compounds or any Exclusively Licensed IP that would interfere with the grant of the licenses resulting from the exercise of such

-28-

Option to GSK hereunder. The grant of the Options by Dynavax hereunder is irrevocable except as provided under Article 12. GSK acknowledges that certain of the Exclusively Licensed IP to the extent that it pertains to compounds which are not Compounds or Products hereunder is subject to the terms and conditions of the [ * ] and that such grant of rights, so long as such grant is consistent with and does not interfere with the grant of exclusive licenses in the Field and in the Territory from the exercise of an affected Option hereunder, shall not be deemed a breach of this Agreement.

4.3 Technology Transfer after Option Exercise. As soon as reasonably practicable after GSK exercises its Option for a Dynavax Program pursuant to Section 4.1 [ * ], Dynavax shall deliver to GSK, at no cost to GSK, all Information and material in its possession and Control relating to the Compounds in such GSK Development Program, including those documents and materials set out in Exhibit G, and any other such Information as may be in Dynavax’s Control and in the possession of any subcontractors (including third party manufacturers) appointed by Dynavax under Section 2.13, in each case in a format to be agreed between the Parties but which is in an electronically editable format suitable for eCTD submission. Dynavax shall provide such technology transfer services as may be reasonably necessary to [ * ] the Compound manufacturing processes at GSK’s or GSK’s Third Party manufacturer’s site; provided that GSK shall be responsible for [ * ] to provide those services reasonably necessary to [ * ] of the Compound manufacturing processes by GSK, and [ * ] from Dynavax therefor. [ * ]. Dynavax shall use Commercially Reasonable Efforts with respect to those activities for which it is responsible to ensure orderly transition and uninterrupted Development of the GSK Development Program.

8.5.2 Prior to Exercise of Option.

(a) Prior to GSK’s exercise of an Option, with respect to any Collaboration IP solely owned by Dynavax or any Dynavax Compound IP that is the subject of such Competitive Infringement, Dynavax shall have the first right to bring and control any such action. Unless subject to an agreement between Dynavax and a Third Party in existence as of the Effective Date that would preclude Dynavax from granting such right to GSK, if Dynavax fails to bring any such action or proceeding within a period of [ * ] Calendar Days after first being notified of such Competitive Infringement, then GSK shall have the right, but not the obligation, to bring and control any such action by counsel of its own choice, and Dynavax shall have the right to be represented in any such action by counsel of its own choice at its own expense.

(b) Prior to GSK’s exercise of an Option, except as provided in Section 8.5.2(a), the Party responsible for Prosecuting and Maintaining a Collaboration Patent shall have the primary right, but not the obligation, to institute, prosecute, and control any action or proceeding with respect thereto by counsel of its own choice, and the other Party shall have the right, at its own expense, to be represented in that action by counsel of its own choice. If the Party having the primary right fails to bring any such action or proceeding within a period of [ * ] Calendar Days after first being notified of such Competitive Infringement, then the other Party shall have the right, but not the obligation, to bring and control any such action by counsel of its own choice, and the Party not bringing the action shall have the right to be represented in any such action by counsel of its own choice at its own expense.

8.5.3 Following Exercise of Option.

8.5.5 Settlement. Any settlement, consent judgment or other disposition of any action or proceeding under this Article 8 shall not (a) include the grant of any license, covenant or other rights to any Third Party that would limit or interfere with or reduce the scope of the subject matter included under the exclusive licenses to be granted or granted to GSK pursuant to the exercise of any of its Options to Programs under Section 4.2.1, or (b) limit or interfere with or reduce the scope of the subject matter claimed in any patent owned (solely or jointly) by the other Party.

8.5.6 Share of Recoveries. If one Party brings any such action or proceeding in accordance with this Section 8.5, the second Party agrees to be joined as a party plaintiff where necessary and to give the first Party reasonable assistance and authority to file and prosecute the suit. The costs and expenses of the Party bringing suit under this Section 8.5 shall be borne by such Party, and any damages or other monetary awards recovered shall be shared as follows: (i) the amount of such recovery actually received by the Party controlling such action shall first be applied to the out-of-pocket costs of such action; and then (ii) any remaining proceeds shall be allocated between the Parties such that the Party bringing suit under this Section 8.5 retains [ * ] and other Party retains [ * ] of such amount. Any such damages or other monetary awards as recovery shall be [ * ] of Net Sales for the purpose of determining royalties due under Article 6 hereunder. A settlement or consent judgment or other voluntary final disposition of a suit under this Section 8.5 may be entered into without the consent of the Party not bringing the suit; provided that such settlement, consent judgment or other disposition does not admit the invalidity or unenforceability of the relevant Patent in the Dynavax Compound Patents, GSK Development Patents, or Collaboration IP, and provided further, that any rights granted under the relevant Patent to continue the infringing activity in such settlement, consent judgment or other disposition shall be limited to those rights that the granting Party otherwise has the right to grant, and provided further, that any settlement, consent judgment or other disposition shall not include the grant of any license, covenant or other rights to any Third Party that would limit or interfere with or reduce the scope of the subject matter included under the exclusive licenses to be granted to GSK pursuant to the exercise of any of its Options to Programs under Section 4.2.1.

8.5.8 Regulatory Data Protection. To the extent required by law or permitted by law, each Party will use Commercially Reasonable Efforts to promptly, accurately and completely list, with the applicable Regulatory Authorities during the Term, all applicable Patents for any Product that such Party intends to, or has begun to, commercialize and that have become the subject of a marketing application submitted to FDA, such listings to include all so called “Orange Book” listings required under the Xxxxx-Xxxxxx Act and all so called “Patent Register” listings as required in Canada. Prior to such listings, the Parties will meet to evaluate and identify all applicable Patents. Notwithstanding the preceding sentence, the Party holding the NDA for the applicable Product will retain final decision-making authority as to the listing of all applicable Patents for such Product, regardless of which Party owns such Patent.

8.6 Other Agreement(s). GSK’s rights under this Article 8 with respect to any Dynavax Compound Patents or Collaboration Patents shall be subject to the rights that one or more Third Parties may have, or the obligations that Dynavax may have, in each case to file, prosecute, maintain, and/or enforce such Patents under the agreement(s) listed in Schedule 8.6, but only to the extent that any of such rights or obligations with respect to any Third Party under any of the Agreements listed in Schedule 8.6 pertain solely to compounds that do not qualify under the definition of Compounds hereunder.

9.3 Press Release; Disclosure of Agreement. On or promptly after the Effective Date, the Parties shall jointly issue a public announcement of the execution of this Agreement in the form attached hereto as Exhibit F. Neither Party shall be free to issue any press release or other public disclosure regarding the Agreement or the Parties’ activities hereunder, or any results or data arising hereunder, except (a) with the other Party’s prior written consent, or (b) for any disclosure that is reasonably necessary to comply with applicable national securities exchange listing requirements or laws, rules or regulations, with the other Party’s consent not to be unreasonably withheld or delayed beyond a time reasonably in advance of the required disclosure deadline necessary to comply with applicable national securities exchange listing requirements or laws, rules or regulations. The Parties agree to consult with each other reasonably and in good faith with respect to the text and timing of any such press releases prior to the issuance thereof, and a Party may not unreasonably withhold consent to such releases. Except to the extent required by law or as otherwise permitted in accordance with this Section 9.3, neither Party shall make any public announcements concerning this Agreement or the subject matter hereof without the prior written consent of the other, which shall not be unreasonably withheld. Each Party agrees to provide to the other Party a copy of any public announcement regarding this Agreement or the subject matter thereof as soon as reasonably practicable under the circumstances prior to its scheduled release. Except under extraordinary circumstances, when the following notice may not be possible but in which event the press release will still be provided to the other Party for comment before release, each Party shall provide the other with an advance copy of any such announcements at least [ * ] prior to its scheduled release. Each Party shall have the right to expeditiously review and recommend changes to any such announcement and, except as otherwise required by laws, rules or regulations, the Party whose announcement has been reviewed shall remove any Confidential Information of the reviewing Party that the reviewing Party reasonably deems to be inappropriate for disclosure. The principles to be observed by Dynavax and GSK in any such permitted public disclosures with respect to this Agreement shall be: accuracy and completeness, the requirements of confidentiality under this Article 9, and the normal business practice in the pharmaceutical and biotechnology industries for disclosures by companies comparable to Dynavax and GSK. Notwithstanding the foregoing, to the extent information regarding this Agreement has already been publicly disclosed in the same context, either Party may subsequently disclose the same information to the public without the consent of the other Party. Each Party shall be permitted to disclose the terms of this Agreement, in each case under appropriate confidentiality provisions substantially equivalent to those of this Agreement, to any actual or potential acquirers, merger partners, and professional advisors. Each Party shall give the other Party a reasonable opportunity to review all filings with the United States Securities and Exchange Commission describing the terms of this Agreement prior to submission of such filings, and shall give due consideration to any reasonable comments by the non-filing Party relating to such filing, including without limitation the provisions of this Agreement for which confidential treatment should be sought.

9.6 Publications. Neither Party or its Affiliates shall publish or publicly disclose the results of any of the Research and/or Development activities conducted by either Party under this Agreement without the prior written consent of the other Party, except as expressly permitted in this Section 9.6 or otherwise in this Agreement. The Parties recognize that it may be useful or required to publish or publicly disclose the results of Research and Development work on Programs, and each Party (and its Affiliates and Sublicensees) shall be free to publish or publicly disclose such results, subject to the prior review by the other Party for patentability and protection of its Confidential Information as described in this Section 9.6. For Dynavax, the publication right conveyed by the preceding sentence shall apply solely to Compounds prior to the exercise of an Option by GSK to the relevant Dynavax Program, if approved by GSK, such approval not to be unreasonably withheld or delayed. The Party that desires to publish results hereunder shall provide to the other Party a copy of such proposed abstract, manuscript, or presentation no less than [ * ] prior to its intended submission for publication. The reviewing Party shall respond in writing promptly and in no event later than [ * ] after receipt of the proposed material, with one or more of the following: (i) comments on the proposed material, which the publishing Party must consider in good faith, (ii) a specific statement of concern, based upon the need to seek patent protection or to block publication if the reviewing Party determines that the proposed disclosure is intellectual property that should be maintained as a trade secret to protect a Compound or any Research and/or Development activities conducted under this Agreement, or (iii) an identification of the reviewing Party’s Confidential Information that is contained in the material reviewed. In the event of concern over patent protection or whether maintaining a trade secret would be a priority, the publishing Party agrees not to submit such publication or to make such presentation that contains such information until the reviewing Party is given a reasonable period of time ([ * ]) to seek patent protection for any material in such publication or presentation which it believes is patentable or to resolve any other issues or to abandon such proposed publication if the reviewing Party reasonably determines in good faith that maintaining such information as a trade secret is a commercially-reasonable priority. Any Confidential Information of such other Party shall be removed. Furthermore, with respect to any proposed abstracts, manuscripts or summaries of presentations by investigators or other Third Parties, such materials shall be subject to review under this Section 9.6 to the extent that GSK or Dynavax (as the case may be) has the right to do so. For clarity, (a) prior to the exercise of the relevant Option to a given Program by GSK, any proposed publication by Dynavax relating to a Dynavax Program or any Compounds shall be subject to review by GSK in accordance with the terms of this Section 9.6, but after the expiration of the relevant Option without exercise by GSK or after the termination of a Program which then reverts to Dynavax, Dynavax shall then be free to publish or publicly disclose any results that relate to any Compounds or Dynavax Products in such Dynavax Program or Dynavax Development Program without any review by GSK under this Section 9.6, unless such proposed disclosure or publication contains any GSK Development IP, in which case GSK shall have the right to review and approve such disclosure as stated under this Section 9.6 above, and (b) after the exercise by GSK of its Option to a Program, except as required by law or securities regulations, Dynavax shall not have the right to make any publication relating to such Dynavax Program or any Compounds or GSK Development Compounds or GSK Products without the prior written consent of GSK, and GSK shall have the right to make any such publication relating to such Dynavax Program or any Compounds or GSK Development Compounds or GSK Products without any review by Dynavax under this Section 9.6.

Each of GSK and Dynavax shall have the right to publish summaries of results from any human clinical trials conducted by such Party under this Agreement on its clinical trials registry, without requiring the consent of the other Party, subject to the last sentence of this Section 9.7; provided, however, that GSK shall have no right, without the consent of Dynavax, to so publish data generated by Dynavax prior to GSK’s exercise of its Option with respect to the relevant Compounds under the relevant Dynavax Program, and, after the exercise of its Option to such Dynavax Program, GSK shall have the right to so publish any previously existing and/or any subsequently arising data that is or may be generated by either Dynavax or GSK or by their respective Affiliates or Sublicensees with respect to the relevant Compound(s) without obtaining the consent of Dynavax, except with respect to any Compounds which are being pursued under a Dynavax Development Program after termination by GSK of such Compounds as GSK Development Compounds or after GSK declines to exercise its Option with respect to such Dynavax Program. In addition, after the exercise of its Option by GSK to a particular Dynavax Program, Dynavax shall not have the right to publish any of such data, without the prior consent of GSK, pertaining to the relevant Compounds or the Dynavax Program, except with respect to any Compounds which are being pursued under a Dynavax Development Program after termination by GSK of such Compounds as GSK Development Compounds. The Parties shall discuss and reasonably cooperate in order to facilitate the process to be employed in order to ensure the publication of any such summaries of human clinical trials data and results as required on the clinical trial registry of each respective Party, and shall provide the other Party via submission to the Joint Patent Subcommittee established under Section 3.1.8, at least [ * ] Calendar Days prior notice to review the clinical trials results to be published for the purposes of preparing any necessary Patent filings.

12.2.1 Termination for Material Breach. Either Party (the “Non-breaching Party”) may, without prejudice to any other remedies available to it at law or in equity, terminate this Agreement, either on a Program-by-Program basis or in its entirety, as may be appropriate to protect the interest of the Non-breaching Party arising from such alleged breach, in the event the other Party (the “Breaching Party”) shall have materially breached or defaulted in the performance of any of its material obligations hereunder either with respect to a particular Program or the Agreement as a whole, and such default shall have continued for [ * ] after written notice thereof was provided to the Breaching Party by the Non-breaching Party, such notice describing with particularity and in detail the alleged material breach.

The right of either Party to terminate this Agreement, or a portion of this Agreement, as provided in this Section 12.2 shall not be affected in any way by such Party’s waiver or failure to take action with respect to any previous default.

miscellaneous

Unless otherwise expressly provided in Section 3.1.4 as not being subject to further review under Section 13.1, in the event of a dispute arising under this Agreement between the Parties, either Party shall have the right to refer such dispute to the respective Executive Officers, and such Executive Officers shall attempt in good faith to resolve such dispute. If the Parties are unable to resolve a given dispute pursuant to this Section 13.1 within [ * ] days of referring such dispute to the Executive Officers, either Party may have the given dispute settled by binding arbitration pursuant to Section 13.2.

13.2 Arbitration Request. If a Party intends to begin an arbitration to resolve a dispute arising under this Agreement, such Party shall provide written notice (the “Arbitration Request”) to the other Party of such intention and the issues for resolution. From the date of the Arbitration Request and until such time as the dispute has become finally settled, the running of the time periods as to which Party must cure a breach of this Agreement becomes suspended as to any breach that is the subject matter of the dispute.

13.2.1 Additional Issues. Within [ * ] Business Days after the receipt of the Arbitration Request, the other Party may, by written notice, add additional issues for resolution.

13.2.2 No Arbitration of Patent Issues.

-67-

13.2.3 Arbitration Procedure. Any arbitration pursuant to this Article 13 will be held in the continental United States at a location to be agreed by the Parties and under the rules of the American Arbitration Association (“AAA”). The arbitration will be governed by the United States Arbitration Act, 9 U.S.C. §§ 1-16, to the exclusion of any inconsistent state laws. The Parties shall mutually agree the rules to govern discovery and the rules of evidence for the arbitration. In the event the parties fail to agree promptly to such rules, The United States Federal Rules of Civil Procedure will govern discovery and the rules of evidence for the arbitration. The arbitration will be conducted by three (3) arbitrators who are knowledgeable in the subject matter at issue in the dispute. The Parties will attempt to select three (3) arbitrators that are each acceptable to both Parties. In the event the Parties fail to agree promptly on three mutually-acceptable arbitrators, one (1) arbitrator will be selected by Dynavax, one (1) arbitrator will be selected by GSK, and the third arbitrator will be selected by mutual agreement of the two (2) arbitrators selected by the Parties. The arbitrators may proceed to an award, notwithstanding the failure of either Party to participate in the proceedings. The arbitrators shall, within fifteen (15) days after the conclusion of the arbitration hearing, issue a written award and statement of decision describing the essential findings and conclusions on which the award is based, including the calculation of any damages awarded. The arbitrators shall be limited in the scope of their authority to resolving only the specific matter which the Parties have referred to arbitration for resolution and shall not have authority to render any decision or award on any other issues. The arbitrators shall be authorized to award compensatory damages, but shall not be authorized to award punitive, special, consequential, or any other similar form of damages, or to reform, modify or materially change this Agreement. The arbitrators also shall be authorized to grant any temporary, preliminary or permanent equitable remedy or relief the arbitrators deem just and equitable and within the scope of this Agreement, including, without limitation, an injunction or order for specific performance. The award of the arbitrators shall be the sole and exclusive remedy of the Parties, except for those remedies that are set forth in this Agreement or which apply to a Party by operation of the applicable provisions of this Agreement, and the Parties hereby expressly agree to waive the right to appeal from the decisions of the arbitrators, and there shall be no appeal to any court or other authority (government or private) from the decision of the arbitrators. Judgment on the award rendered by the arbitrators may be enforced in any court having competent jurisdiction thereof, subject only to revocation on grounds of fraud or clear bias on the part of the arbitrators. Notwithstanding anything contained in this Section 13.2 to the contrary, each Party shall have the right to institute judicial proceedings against the other Party or anyone acting by, through or under such other Party, in order to seek to enforce the instituting Party’s rights hereunder through specific performance, injunction or similar equitable relief.

13.2.4 Costs. Each Party shall bear its own attorneys’ fees, costs, and disbursements arising out of the arbitration, and shall pay an equal share of the fees and costs of the arbitrators; provided, however, that the arbitrators shall be authorized to determine whether a Party is the prevailing Party, and if so, to award to that prevailing Party reimbursement for its reasonable attorneys’ fees, costs and disbursements (including, for example, expert witness fees and expenses, photocopy charges and travel expenses).

13.2.5 Preliminary Injunctions. Notwithstanding anything in this Agreement to the contrary, a Party may seek a temporary restraining order or a preliminary injunction from any court of competent jurisdiction in order to prevent immediate and irreparable injury, loss, or damage on a provisions basis, pending the decision of the arbitrators on the ultimate merits of any dispute.

13.2.6 Confidentiality. All proceedings and decisions of the arbitrators shall be deemed Confidential Information of each of the Parties, and shall be subject to Article 9.

13.4 Assignment. Either Party may assign this Agreement to any Affiliate of such Party without the consent of the other Party; provided, that such Party provides the other Party with written notice of such assignment and remains fully liable for the performance of such Party’s obligations hereunder by such Affiliate. Further, each Party may assign this Agreement without the consent of the other Party to its successor in interest by way of merger, acquisition, or sale of all or substantially all of its assets to which this Agreement relates; provided, that such Party provides the other Party with written notice of such assignment; provided further, that if such assignment involves a transaction in which Dynavax: (a) merges or consolidates with any other entity (other than a wholly-owned subsidiary of Dynavax); or (b) effects any other transaction or series of transactions, such that the stockholders of Dynavax immediately prior thereto, in the aggregate, no longer own, directly or indirectly, beneficially or legally, at least fifty percent (50%) of the outstanding voting securities or capital stock of the surviving entity following the closing of such merger, consolidation, other transaction or series of transactions (a “Change of Control Event”), then Dynavax will notify GSK prior to the closing of such Change of Control Event, and [ * ]. The terms and conditions of this Agreement shall be binding upon and shall inure to the benefit of the successors, heirs, administrators and permitted assigns of the Parties. Any purported assignment in violation of this Section 13.4 shall be null and void.

13.5 Performance Warranty. Each Party hereby acknowledges and agrees that it shall be responsible for the full and timely performance as and when due under, and observance of all the covenants, terms, conditions and agreements set forth in this, Agreement by its Affiliate(s) and Sublicensees.

13.6 Force Majeure. No Party shall be held liable or responsible to the other Party nor be deemed to be in default under, or in breach of any provision of, this Agreement for failure or delay in fulfilling or performing any obligation (other than a payment obligation) of this Agreement when such failure or delay is due to force majeure, and without the fault or negligence of the Party so failing or delaying. For purposes of this Agreement, force majeure is defined as causes beyond the control of the Party, including, without limitation, acts of God; acts, regulations, or laws of any government; war; civil commotion; destruction of production facilities or materials by fire, flood, earthquake, explosion or storm; labor disturbances; epidemic; and failure of public utilities or common carriers. In such event Dynavax or GSK, as the case may be, shall immediately notify the other Party of such inability and of the period for which such inability is expected to continue. The Party giving such notice shall thereupon be excused from such of its obligations under this Agreement as it is thereby disabled from performing for so long as it is so disabled for up to a maximum of ninety (90) days, after which time Dynavax and GSK shall promptly meet to discuss in good faith how to best proceed in a manner that maintains and abides by the Agreement. To the extent possible, each Party shall use reasonable efforts to minimize the duration of any force majeure.

Evidence for Proof of Mechanistic Effect

Quantitative measurements of multiple immunological parameters will be taken from treated subjects for example, cytokine/chemokine profiles, leukocyte CD antigens and genome-wide gene expression profiling, impact on signaling pathways and if appropriate on tissue pathology. Assays will be performed to determine extent of target binding. Criteria for positive [ * ] would be based on evidence of pharmacology, PK/PD relationship and resulting relevant mechanistic efficacy, with supportive trends in clinical markers if the study is within a patient population.

The desired goal is to achieve an early proof of pharmacological and mechanistic activity to develop PD markers, PK/PD modeling, and safety information, that will allow informed decision-making on progression of the asset and selection of smaller numbers of dose groups for the larger Phase IIb PoC trial, thus enabling that study to be up to 25% smaller]

GlaxoSmithKline and Dynavax Announce Worldwide Strategic Alliance

-- Developing First-in-Class Endosomal TLR Inhibitors for

Autoimmune and Inflammatory Diseases --

London, United Kingdom, Philadelphia, PA, and Berkeley, CA – December 16, 2008 – GlaxoSmithKline (LSE and NYSE: GSK) and Dynavax Technologies Corporation (NASDAQ: DVAX) today announced a worldwide strategic alliance to discover, develop and commercialize novel inhibitors of endosomal Toll-like Receptors (TLRs) for the treatment of immuno-inflammatory diseases. TLRs are key receptors of the innate immune system that can induce strong inflammatory responses.

Under the terms of the alliance, Dynavax will receive an initial payment of $10 million for which GSK will receive an exclusive option over four programs targeting autoimmune and inflammatory diseases such as lupus, psoriasis, and rheumatoid arthritis.

“Our alliance with GSK provides an opportunity to create an entirely new product franchise for Dynavax,” commented Dino Dina, M.D., President and Chief Executive Officer of Dynavax. “Our TLR inhibitors have the potential to create significant value for our newest collaborator GSK as well as for our stockholders. Alliances with major pharmaceutical companies have enabled Dynavax to establish a diverse pipeline of innovative products, while contributing valuable cash for our programs.”

Dynavax is to conduct research and early clinical development in up to four programs and is 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 will carry out further development and commercialization of these products. Dynavax will receive tiered, up to double-digit royalties on sales and has retained an option to co-develop and co-promote one specified product.

Dynavax has pioneered a new approach to treating autoimmune and inflammatory diseases with its first-in-class oligonucleotide-based endosomal TLR inhibitors, called immunoregulatory sequences (IRS). Dynavax’s lead inhibitor drug candidate, DV1079, is a bifunctional inhibitor of TLR7 and TLR9, and is expected to enter clinical development in the fourth quarter of 2009.

“We are committed to using our expertise, in collaboration with Dynavax, to research and develop new therapeutics that can improve the lives of patients with conditions like systemic lupus erythematosus, psoriasis and rheumatoid arthritis,” commented Xxxx Xxxxxx Xxxxxxxxx-Xxxxx, Ph.D., Senior Vice President and Head of

the Immuno-Inflammation Centre of Excellence for Drug Discovery at GSK. “Dynavax is a recognized pioneer in the scientific community for its innovation of endosomal TLR inhibitors which prevent immune signaling in autoimmune and inflammatory diseases.”

Dynavax Conference Call

Dynavax will webcast a conference call today at 9:00 a.m. ET (6:00 a.m. PT) to discuss this alliance. The live and archived webcast can be accessed by visiting the investor relations section of the Company's Web site at xxxx://xxxxxxxxx.xxxxxxx.xxx/xxxxxx.xxx.

About TLR Inhibitors

Dynavax’s endosomal TLR inhibitors are a novel class of oligonucleotides, called immunoregulatory sequences (IRS), that specifically inhibit the TLR-induced inflammatory response associated with autoimmune and inflammatory diseases. Preclinical data from animal model studies show Dynavax’s TLR inhibitors block IFN-alpha and also reduce symptoms in multiple autoimmune diseases models, such as lupus, inflammatory skin disorders, and rheumatoid arthritis.

About Dynavax

Dynavax Technologies Corporation, a clinical-stage biopharmaceutical company, discovers and develops a diversified, well-funded pipeline of novel Toll-like Receptor (TLR) product candidates.
