 DYNAVAX TECHNOLOGIES CORPORATION 
 2004 STOCK INCENTIVE PLAN 
 RESTRICTED STOCK UNIT AWARD AGREEMENT 
 Pursuant to the Restricted Stock Unit Grant Notice (“Grant Notice”) and this Restricted Stock Unit Award Agreement (“Agreement”), Dynavax Technologies Corporation (the
“Company”) has granted you a delayed award of Restricted Stock pursuant to the Company’s 2004 Stock Incentive Plan (the “Plan”) covering the number of restricted stock units
(“RSUs”) as indicated in the Grant Notice (collectively, the “Award”). This Agreement shall be deemed to be signed by the Company and you upon your signing of the Grant Notice. Defined terms not
explicitly defined in this Agreement but defined in the Plan shall have the same definitions as in the Plan. Except as expressly provided herein, in the event of any conflict between the terms of this Agreement and the Plan, the terms of the Plan
shall control. The details of this Award, in addition to those set forth in the Grant Notice, are as follows. 
 1. GRANT
OF AWARD. This Award represents the right to earn and be issued on a future date the number of shares of Common Stock as indicated in the Grant Notice. Subject to adjustment and the terms and
conditions as provided herein and in the Plan, each RSU shall represent the right to receive one share of Common Stock. As of the Date of Grant, the Company will credit to a bookkeeping account maintained by the Company for your benefit (the
“Account”) the number of shares of Common Stock subject to this Award. This Award was granted in consideration of your services to the Company. Except as provided in Section 12, you will not be required to make any
payment to the Company (other than services to the Company) with respect to your receipt of this Award, the vesting of the RSUs, or the delivery of the shares of underlying Common Stock. 
 2. VESTING. The RSUs will vest, if at all, as provided in the Vesting Schedule set forth in your Grant Notice and
the Plan, provided that vesting shall cease upon the termination of your Continuous Service. Upon such termination of your Continuous Service, the shares credited to the Account that were not vested on the date of such termination shall be forfeited
to the Company and you shall have no further right, title or interest in or to such underlying shares of Common Stock. 
 3.
VESTING ACCELERATION. 
 (a) If your employment is terminated in an Involuntary Termination except
following a Change of Control, then you will be entitled to receive pro rata vesting credit under this Award, such that a number of RSUs will vest equal to the product of (i) the number of RSUs subject to this Award, and (ii) the
quotient obtained by dividing (x) the number of full calendar years between the Vesting Commencement Date specified in the Grant Notice and the date of the termination of your employment in an Involuntary Termination, by (y) 3. 

(b) In the event of a Change of Control and you: (i) are offered and accept a position with the New Company, or (ii) are not offered
a position with the New Company that is “comparable” to your position with the Company, then immediately prior to the effective date of the Change of Control this Award shall immediately vest in full. For purposes of this
Section 3(b), a position with the New Company shall be considered “comparable” to your position with 

 
the Company if such position would not form the basis for your voluntary termination of employment that would constitute an Involuntary Termination;
provided, however, that for purposes of this Section 3(b) only, clause (ii)(A) of the definition of Involuntary Termination shall be applied in a manner that presumes that there is a material reduction of job duties or responsibilities
if your position with the New Company is as part of a subsidiary or division of the New Company and the scope of such duties or responsibilities is limited to such subsidiary or division and does not include the entire business operations of the New
Company. 
 4. NUMBER OF RSUS AND SHARES OF
COMMON STOCK. 
 (a) The number of RSUs subject to this Award and the number of shares of Common
Stock deliverable with respect to such RSUs may be adjusted from time to time for changes in capitalization as described in Section 10 of the Plan. You shall receive no benefit or adjustment to this Award with respect to any cash dividend or
other distribution that does not result from changes in capitalization as described in Section 10 of the Plan; provided, however, that this sentence shall not apply with respect to any shares of Common Stock that are delivered to you in
connection with this Award after such shares have been delivered to you. 
 (b) Any additional RSUs, shares of Common Stock, cash or
other property that becomes subject to the Award pursuant to this Section 4 shall be subject, in a manner determined by the Board, to the same forfeiture restrictions, restrictions on transferability, and time and manner of delivery as
applicable to the other RSUs and Common Stock covered by this Award. 
 (c) Notwithstanding the provisions of this Section 4, no
fractional RSUs or rights for fractional shares of Common Stock shall be created pursuant to this Section 4. The Board shall, in its discretion, determine an equivalent benefit for any fractional RSUs or fractional shares that might be created
by the adjustments referred to in this Section 4. 
 5. DELIVERY OF SHARES
OF COMMON STOCK. 
 (a) Subject to the provisions of this Agreement, in the event one
or more RSUs vests, the Company shall deliver to you one share of Common Stock for each RSU that vests on the applicable vesting date. However, if a scheduled delivery date falls on a date that is not a business day, such delivery date shall instead
fall on the next following business day. The form of such delivery (e.g., a stock certificate or electronic entry evidencing such shares) shall be determined by the Company. 
 (b) Notwithstanding the foregoing, in the event that you are subject to the Company’s Insider Trading Policy in effect from time to
time and any shares covered by this Award are scheduled to be delivered on a day (the “Original Delivery Date”) that occurs during a “blackout period” applicable to you, as determined by the Company in accordance
with such policy, then such shares shall not be delivered on such Original Delivery Date and shall instead be delivered on the first business day after the end of the “blackout period” applicable to you, but in no event later than the
later of: (i) December 31st of the calendar year of the Original Delivery Date, or (ii) the fifteenth (15th) day of the third calendar month following the Original Delivery Date. 

 6. DIVIDENDS. You shall receive no benefit or adjustment to your
Award with respect to any cash dividend, stock dividend or other distribution that does not result from a change in capitalization as described in Section 10 of the Plan; provided, however, that upon delivery of shares of Common Stock,
you shall exercise all rights and privileges of a stockholder of the Company with respect to such shares including the right to receive any dividends which may be paid with respect to such shares. 
 7. SECURITIES LAW COMPLIANCE. You may not be issued any Common Stock under this Award
unless either (i) the shares of Common Stock are then registered under the Securities Act, or (ii) the Company has determined that such issuance would be exempt from the registration requirements of the Securities Act. This Award must also
comply with other applicable laws and regulations governing the Award, and you shall not receive such Common Stock if the Company determines that such receipt would not be in material compliance with such laws and regulations. 
 8. RESTRICTIVE LEGENDS. The Common Stock issued under this Award shall be endorsed with appropriate
legends, if any, determined by the Company. 
 9. TRANSFER RESTRICTIONS. Prior to the
time that shares of Common Stock have been delivered to you, you may not transfer, pledge, sell or otherwise dispose of the shares in respect of this Award. This Award is not transferable, except by will or by the laws of descent and distribution.
Notwithstanding the foregoing, by delivering written notice to the Company, in a form satisfactory to the Company, you may designate a third party who, in the event of your death, shall thereafter be entitled to receive any distribution of Common
Stock to which you were entitled at the time of your death pursuant to this Agreement. 
 10. AWARD NOT
A SERVICE CONTRACT. This Award is not an employment or service contract, and nothing in this Award shall be deemed to create in any way whatsoever any obligation on your part to
continue in the service of the Company or any Related Entity, or on the part of the Company or any Related Entity to continue such service. In addition, nothing in this Award shall obligate the Company or any Related Entity, their respective
stockholders, boards of directors or employees to continue any relationship that you might have as an Employee or Consultant of the Company or any Related Entity. 
 11. UNSECURED OBLIGATION. This Award is unfunded, and even as to any RSUs that vest, you shall be considered an unsecured creditor of the Company with respect to the
Company’s obligation, if any, to issue Common Stock pursuant to this Agreement. You shall not have voting or any other rights as a stockholder of the Company with respect to the Common Stock acquired pursuant to this Agreement until such Common
Stock is issued to you pursuant to Section 5. Upon such issuance, you will obtain full voting and other rights as a stockholder of the Company with respect to the Common Stock so issued. Nothing contained in this Agreement, and no action taken
pursuant to its provisions, shall create or be construed to create a trust of any kind or a fiduciary relationship between you and the Company or any other person. 

 12. WITHHOLDING OBLIGATIONS. 
 (a) On or before the time you vest in your RSUs or receive a distribution of Common Stock pursuant to this Award, or at any time thereafter as
requested by the Company, you hereby authorize any required withholding from payroll, other any amounts payable to you, and any shares of Common Stock issuable to you, and you otherwise agree to make adequate provision for any sums required to
satisfy the federal, state, local and foreign tax withholding obligations of the Company or any Related Entity which arise in connection with this Award (the “Withholding Taxes”). 
 (b) If expressly permitted by the Company, you may direct the Company to withhold shares of Common Stock with a Fair Market Value (measured as of
the date shares of Common Stock are delivered pursuant to Section 5) equal to the amount of such Withholding Taxes; provided, however, that the number of such shares of Common Stock so withheld shall not exceed the amount necessary to
satisfy the Company’s required tax withholding obligations using the minimum statutory withholding rates for federal, state, local and foreign tax purposes, including payroll taxes, that are applicable to supplemental taxable income.

 (c) Unless the tax withholding obligations of the Company and/or any Related Entity are satisfied, the Company shall have no
obligation to deliver to you any Common Stock. 
 (d) In the event the Company’s obligation to withhold arises prior to the
delivery to you of shares of Common Stock or it is determined after the delivery of Common Stock to you that the amount of the Company’s withholding obligation was greater than the amount withheld by the Company, you agree to indemnify and hold
the Company harmless from any failure by the Company to withhold the proper amount. 
 13. BEST
AFTER-TAX. 
 (a) If any payment or benefit you would receive pursuant to an event described in
Section 280G(b)(2)(A)(i) of the Code from the Company or otherwise (“Payment”) would (i) constitute a “parachute payment” within the meaning of Section 280G of the Code, and (ii) but for this
sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then such Payment shall be equal to the Reduced Amount. The “Reduced Amount” shall be either
(x) the largest portion of the Payment that would result in no portion of the Payment being subject to the Excise Tax, or (y) the largest portion, up to and including the total, of the Payment, whichever amount, after taking into account
all applicable federal, state and local employment taxes, income taxes, and the Excise Tax (all computed at the highest applicable marginal rate), results in your receipt of the greatest economic benefit notwithstanding that all or some portion of
the Payment may be subject to the Excise Tax. If a reduction in payments or benefits constituting “parachute payments” is necessary so that the Payment equals the Reduced Amount, reduction shall occur in a manner necessary to provide you
with the greatest economic benefit. If more than one manner of reduction of payments or benefits necessary to arrive at the Reduced Amount yields the greatest economic benefit, the payments and benefits shall be reduced pro rata. 

 (b) The independent registered public accounting firm engaged by the Company for general audit
purposes as of the day prior to the effective date of the event described in Section 280G(b)(2)(A)(i) of the Code shall perform the foregoing calculations. If the independent registered public accounting firm so engaged by the Company is
serving as accountant or auditor for the individual, entity or group effecting such event, the Company shall appoint a nationally recognized independent registered public accounting firm to make the determinations required hereunder. The Company
shall bear all expenses with respect to the determinations by such independent registered public accounting firm required to be made hereunder. The independent registered public accounting firm engaged to make the determinations hereunder shall
provide its calculations, together with detailed supporting documentation, to the Company and you within 30 calendar days after the date on which your right to a Payment is triggered (if requested at that time by the Company or you) or such other
time as requested by the Company or you. Any good faith determinations of the independent registered public accounting firm made hereunder shall be final, binding and conclusive upon the Company and you. 
 14. NOTICES. Any notices required to be given or delivered to the Company under the terms of this Award shall be in
writing and addressed to the Company at its principal corporate offices. Any notice required to be given or delivered to you shall be in writing and addressed to your address as on file with the Company at the time notice is given. All notices shall
be deemed effective upon personal delivery or upon deposit in the U.S. mail, postage prepaid and properly addressed to the party to be notified. 
 15. HEADINGS. The headings of the Sections in this Agreement are inserted for convenience only and shall not be deemed to constitute a part of this Agreement or to affect the meaning of this Agreement.

 16. AMENDMENT. This Agreement may be amended only by a writing executed by the Company and you which
specifically states that it is amending this Agreement. Notwithstanding the foregoing, this Agreement may be amended solely by the Company by a writing which specifically states that it is amending this Agreement, so long as a copy of such amendment
is delivered to you, and provided that no such amendment adversely affecting your rights hereunder may be made without your written consent. Without limiting the foregoing, the Company reserves the right to change, by written notice to you, the
provisions of this Agreement in any way it may deem necessary or advisable to carry out the purpose of the grant as a result of any change in applicable laws or regulations or any future law, regulation, ruling, or judicial decision, provided that
any such change shall be applicable only to rights relating to that portion of the Award that has not been delivered to you in Common Stock pursuant to Section 5. 
 17. MISCELLANEOUS. 
 (a) The rights and obligations of the Company under this
Award shall be transferable by the Company to any one or more persons or entities, and all covenants and agreements hereunder shall inure to the benefit of, and be enforceable by the Company’s successors and assigns. 

 (b) You agree upon request to execute any further documents or instruments necessary or desirable
in the sole determination of the Company to carry out the purposes or intent of this Award. 
 (c) You acknowledge and agree that you
have reviewed this Award in its entirety, have had an opportunity to obtain the advice of counsel prior to executing and accepting this Award and fully understand all provisions of this Award.

securities exchanges as may be required. 
 (e) All obligations of the Company under the Plan and this Agreement shall be binding on
any successor to the Company, whether the existence of such successor is the result of a direct or indirect purchase, merger, consolidation, or otherwise, of all or substantially all of the business and/or assets of the Company. 
 18. GOVERNING PLAN DOCUMENT. This Award is subject to all the provisions of the Plan,
the provisions of which are hereby made a part of this Award, and is further subject to all interpretations, amendments, rules and regulations which may from time to time be promulgated and adopted pursuant to the Plan. In the event of any conflict
between the provisions of this Award and those of the Plan, the provisions of the Plan shall control; provided, however, that Section 5 of this Agreement shall govern the timing of any distribution of Common Stock under this Award. The
Company shall have the power to interpret the Plan and this Agreement and to adopt such rules for the administration, interpretation, and application of the Plan as are consistent therewith and to interpret or revoke any such rules. All actions
taken and all interpretations and determinations made by the Board shall be final and binding upon you, the Company, and all other interested persons. No member of the Board shall be personally liable for any action, determination, or interpretation
made in good faith with respect to the Plan or this Agreement. 
 19. EFFECT ON OTHER
EMPLOYEE BENEFIT PLANS. The value of the Award subject to this Agreement shall not be included as compensation, earnings, salaries, or other similar terms used when calculating benefits

 Exhibit 10.37 
 DYNAVAX TECHNOLOGIES CORPORATION 
 MANAGEMENT CONTINUITY AND SEVERANCE AGREEMENT 

 Amended October 3, 2008 
 This Management Continuity and Severance Agreement (the “Agreement”) is dated as of October 15, 2003, by and between Dino Dina, President and Chief Executive Officer, Dynavax Technologies Corporation
(“Employee”), and Dynavax Technologies Corporation, a Delaware corporation (the “Company” or “Dynavax”). 
 RECITALS 
 A. It is expected that another company may from time to time consider the possibility of acquiring the
Company or that a change in control may otherwise occur, with or without the approval of the Company’s Board of Directors. The Board of Directors recognizes that such consideration can be a distraction to Employee and can cause Employee to
consider alternative employment opportunities. The Board of Directors has determined that it is in the best interests of the Company to assure that the Company will have the continued dedication and objectivity of the Employee, notwithstanding the
possibility, threat, or occurrence of a Change of Control (as defined below) of the Company. 
 B. The Company’s Board of
Directors believes it is in the best interests of the Company to retain Employee and provide incentives to Employee to continue in the service of the Company. 
 C. The Board of Directors further believes that it is imperative to provide Employee with certain benefits upon a Change of Control and, under certain circumstances, upon termination of Employee’s
employment in connection with a Change of Control and independent of a Change of Control, which benefits are intended to provide Employee with encouragement to Employee to remain with the Company, notwithstanding the possibility of a Change of
Control or an employment termination. 
 D. To accomplish the foregoing objectives, the Board of Directors has directed the Company,
upon execution of this Agreement by Employee, to agree to the terms provided in this Agreement. 
 Now therefore, in consideration of the
mutual promises, covenants, and agreements contained herein, and in consideration of the continuing employment of Employee by the Company, the parties hereto agree as follows: 
 1. At-Will Employment. The Company and Employee acknowledge that Employee’s employment is and shall continue to be at-will, as defined
under applicable law, and that Employee’s employment with the Company may be terminated by either party at any time for any or no reason. If Employee’s employment terminates for any reason, Employee shall not 

  

 -1- 

 
be entitled to any payments, benefits, damages, award, or compensation other than as provided in this Agreement, and as may otherwise be available in
accordance with the terms of the Company’s established employee plans and written policies at the time of termination. The terms of this Agreement shall terminate upon the earlier of: (i) the date on which Employee ceases to be employed by
the Company, other than as a result of an Involuntary Termination by the Company without Cause; or (ii) the date that all obligations of the parties hereunder have been satisfied. A termination of the terms of this Agreement pursuant to the
preceding sentence shall be effective for all purposes, except that such termination shall not affect the payment or provision of compensation or benefits on account of a termination of employment occurring prior to the termination of the terms of
this Agreement. The rights and duties created by this Section 1 may not be modified in any way except by a written agreement executed by the Chief Executive Officer (“CEO”) of the Company upon direction from the Board of Directors, or
by the Chairman of the Board in the case of the CEO. 
 2. Benefits upon Termination of Employment. 
 (a) Termination for Cause. If Employee’s employment is terminated for Cause at any time, then Employee shall not be entitled to
receive payment of any severance benefits. Employee will receive payment for all salary as of the date of Employee’s termination of employment and Employee’s benefits will be continued under the Company’s then existing benefit plans
and policies in accordance with such plans and policies in effect on the date of termination and in accordance with applicable law. 
 (b)
Voluntary Resignation. If Employee voluntarily resigns from the Company (the Employee’s employment does not end by reason of Involuntary Termination), then Employee shall not be entitled to receive payment of any severance benefits.
Employee will receive payment for all salary as of the date of Employee’s termination of employment and Employee’s benefits will be continued under the Company’s then existing benefit plans and policies in accordance with such plans
and policies in effect on the date of termination and in accordance with applicable law. 
 (c) Involuntary Termination. If
Employee’s employment is terminated in an Involuntary Termination except following a Change of Control, then Employee shall be entitled to: (1) a lump-sum cash severance payment equal to twelve (12) months of Employee’s then
current annual base salary (less appropriate withholding deductions); (2) twelve (12) months of COBRA Continuation paid by the Company if COBRA Continuation is elected; (3) an additional twelve (12) months vesting of
Employee’s stock options to purchase the Company’s Common Stock; and (4) pursuant to the Dynavax Technologies Corporation 2004 Stock Incentive Plan, ninety (90) days to exercise vested options. 
 (d) Termination for Death or Disability. If Employee’s employment terminates due to Employee’s death, then Employee’s
beneficiary will receive any salary earned (less appropriate withholding deductions) through the date of termination of employment. If Employee’s employment terminates due to becoming disabled, all salaries due to Employee will be paid through
the date of inception of Employee’s disability. 
  

 -2- 

 In the event of termination for either death or disability, the exercise period of all vested options
granted to Employee by the Company is extended to twelve (12) months from the date of termination of employment. 
 3. Benefits
upon a Change of Control. 
 (a) Treatment of Stock Options. In the event of a Change of Control and the Employee:
(i) is offered and accepts a position with the New Company, or (ii) is not offered a position with the New Company that is comparable to the Employee’s position with the Company, then immediately prior to the effective date of the
Change of Control an additional two (2) years vesting of Employee’s stock options to purchase the Company’s Common Stock granted to Employee over the course of his employment with the Company and held by Employee on the effective date
of a Change of Control shall immediately vest on such date as to that number of shares that would have vested in accordance with the terms of the Stock Incentive Plan, as amended. “New Company,” as used in this Section 3(a), shall
mean: (a) in the case of a Change of Ownership (as defined in Section 4(a)(i) below), the Company; (b) in the case of a Merger (as defined in Section 4(a)(ii) below), the surviving entity; or (c) in the case of a Sale of
Assets (as described in section 4(a)(ii) below), the purchaser of all or substantially all of the Company’s assets. For purposes of this Section 3(a), a position with the New Company shall be considered “comparable” to the
Employee’s position with the Company if such position would not form the basis for Employee’s voluntary termination of employment that would constitute an Involuntary Termination; provided, however, that for purposes of this
Section 3(a) only, Section 4(c)(ii)(A) shall be applied in a manner that presumes that there is a material reduction of job duties or responsibilities if Employee’s position with the New Company is as part of a subsidiary or division
of the New Company and the scope of such duties or responsibilities is limited to such subsidiary or division and does not include the entire business operations of the New Company. 
 (b) Severance. In the event of a Change of Control and Employee’s employment is terminated for any reason, including voluntary
resignation, and such termination results in a “separation from service” within the meaning of Treasury Regulation Section 1.409A-1(h) without regard to any permissible alternative definition thereunder (a “Termination”)
within twenty-four (24) months following such Change of Control, Employee shall be entitled to: (1) a lump-sum cash severance payment equal to twelve (12) months of Employee’s then current annual base salary, less applicable
withholding deductions, payable six (6) months after the date of the Termination; (2) a lump-sum cash payment equal to the Employee’s target incentive bonus of sixty percent (60%) (or such higher percentage then in effect under
the management incentive program or other similar bonus program) of the Employee’s then current annual base salary, less applicable withholding deductions, payable six (6) months after the date of the Termination; (3) twelve
(12) months Company-paid COBRA continuation coverage upon Employee’s election of COBRA Continuation Coverage; and (4) the extension of exercisability of all stock options to purchase the Company’s Common Stock for a period of
three (3) years following termination of employment (but in any event not beyond each option’s expiration date). 
  

 -3- 

 4. Definition of Terms. The following terms referred to in this Agreement shall have the
following meanings: 
 (a) Change of Control. “Change of Control” shall mean the occurrence of any of
the following events: 
 (i) Change of Ownership. Any “Person” (as such term is used in Sections
13(d) and 14(d) of the Securities Exchange Act of 1934, as amended) is or becomes the “Beneficial Owner” (as defined in Rule 13d-3 under said Act), directly or indirectly, of securities of the Company representing 50% or more of the total
voting power represented by the Company’s then outstanding voting securities; or 
 (ii) Merger/Sale of
Assets. A merger or consolidation of the Company whether or not approved by the Board, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to
represent (either by remaining outstanding or by being converted into voting securities of the surviving entity) at least 50% of the total voting power represented by the voting securities of the Company or such surviving entity outstanding
immediately after such merger or consolidation, or the stockholders of the Company approve a plan of complete liquidation of the Company or an agreement for the sale or disposition by the Company of all or substantially all of the Company’s
assets. 
 (b) Cause. “Cause” shall mean: (i) gross negligence or willful misconduct in the
performance of Employee’s duties to the Company, where such gross negligence or willful misconduct has resulted or is likely to result in substantial and material damage to the Company or its subsidiaries; (ii) repeated unexplained or
unjustified absence from the Company; (iii) a material and willful violation of any federal or state law; (iv) commission of any act of fraud with respect to the Company; or (v) conviction of a felony or a crime involving moral
turpitude causing material harm to the standing and reputation of the Company, in each case as determined in good faith by the Board. 
 (c) Involuntary Termination. “Involuntary Termination” shall mean: (i) any termination by the Company other than for Cause; or (ii) Employee’s voluntary termination following
(A) a material reduction or change in job duties, responsibilities, and requirements inconsistent with the Employee’s position with the Company and the Employee’s prior duties, responsibilities, and requirements, or a material change
in the level of management to which the Employee reports; (B) any material reduction of Employee’s base compensation (other than in connection with a general decrease in base salaries for most officers of the successor corporation); or
(C) Employee’s refusal to relocate to a facility or location more than 35 miles from the Company’s current location. Notwithstanding the foregoing, an Involuntary Termination pursuant to the foregoing clause (ii) shall only be
considered to occur if (x) Employee provides written notice to the Company of the existence of the condition that forms the basis for such resignation within 90 days following its initial existence; (y) upon such notice, the Company does
not cure such condition within 30 days thereafter; and (z) Employee’s resignation occurs not later than 180 days after the occurrence of the condition giving rise to the resignation right.

 5. Conflicts. Employee represents that his performance of all the terms of this Agreement
will not breach any other agreement to which Employee is a party. Employee has not entered, and will not during the term of this Agreement enter, into any oral or written agreement in conflict with any of the provisions of this Agreement. Employee
further represents that he is entering into or has entered into an employment relationship with the Company of his own free will and that he has not been solicited as an employee in any way by the Company. 
 6. Successors. Any successor to the Company (whether direct or indirect and whether by purchase, lease, merger, consolidation, liquidation,
or otherwise) to all or substantially all of the Company’s business and/or assets shall assume the obligations under this Agreement and agree expressly to perform the obligations under this Agreement in the same manner and to the same extent as
the Company would be required to perform such obligations in the absence of a succession. The terms of this Agreement and all of Employee’s rights hereunder and thereunder shall inure to the benefit of, and be enforceable by, Employee’s
personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees, and legatees. 
 7.
Notice. Notices and all other communications contemplated by this Agreement shall be in writing and shall be deemed to have been duly given when personally delivered or when mailed by U.S. registered or certified mail, return receipt
requested and postage prepaid. Mailed notices to Employee shall be addressed to Employee at the home address that Employee most recently communicated to the Company in writing. In the case of the Company, mailed notices shall be addressed to its
corporate headquarters, and all notices shall be directed to the attention of its Secretary. 
 8. Parachute Payments.

 (a) If any payment or benefit Employee would receive pursuant to a Change of Control from the Company or otherwise
(“Payment”) would (i) constitute a “parachute payment” within the meaning of Section 280G of the Internal Revenue Code of 1988, as amended (the “Code”), and (ii) but for this sentence, be subject
to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then such Payment shall be equal to the Reduced Amount. The “Reduced Amount” shall be either (x) the largest portion of the Payment that
would result in no portion of the Payment being subject to the Excise Tax, or (y) the largest portion, up to and including the total, of the Payment, whichever amount, after taking into account all applicable federal, state and local employment
taxes, income taxes, and the Excise Tax (all computed at the highest applicable marginal rate), results in Employee’s receipt of the greatest economic benefit notwithstanding that all or some portion of the Payment may be subject to the Excise
Tax. If a reduction in payments or benefits constituting “parachute payments” is necessary so that the Payment equals the Reduced Amount, reduction shall occur in a manner necessary to provide Employee with the greatest economic benefit.
If more than one manner of reduction of payments or benefits necessary to arrive at the Reduced Amount yields the greatest economic benefit, the payments and benefits shall be reduced pro rata. 
 (b) The independent registered public accounting firm engaged by the Company for general audit purposes as of the day prior to the effective date
of the event described in Section 280G(b)(2)(A)(i) of the Code shall perform the foregoing calculations. If 

  

 -5- 

 
the independent registered public accounting firm so engaged by the Company is serving as accountant or auditor for the individual, entity or group effecting
such event, the Company shall appoint a nationally recognized independent registered public accounting firm to make the determinations required hereunder. The Company shall bear all expenses with respect to the determinations by such independent
registered public accounting firm required to be made hereunder. The independent registered public accounting firm engaged to make the determinations hereunder shall provide its calculations, together with detailed supporting documentation, to the
Company and Employee within thirty (30) calendar days after the date on which Employee’s right to a Payment is triggered (if requested at that time by the Company or Employee) or such other time as requested by the Company or Employee. Any
good faith determinations of the independent registered public accounting firm made hereunder shall be final, binding and conclusive upon the Company and Employee. 
 9. Miscellaneous Provisions. 
 (a) No Duty to Mitigate. Employee shall not be
required to mitigate the amount of any payment contemplated by this Agreement (whether by seeking new employment or in any other manner), nor shall any such payment be reduced by any earnings that Employee may receive from any other source.

 (b) Waiver. No provision of this Agreement shall be modified, waived, or discharged unless the modification, waiver, or
discharge is agreed to in writing and signed by Employee and by an authorized officer of the Company (other than Employee). No waiver by either party of any breach of, or of compliance with, any condition or provision of this Agreement by the other
party shall be considered a waiver of any other condition or provision or of the same condition or provision at another time. 
 (c)
Whole Agreement. No agreements, representations, or understandings (whether oral or written and whether expressed or implied) which are not expressly set forth in this Agreement have been made or entered into by either party with respect
to the subject matter hereof, except as set forth in the employment offer letter from the Company to the Employee dated July 14, 1998. This Agreement supersedes any agreement of the same title and concerning similar subject matter dated prior
to the date of this Agreement, and by execution of this Agreement both parties agree that any such predecessor agreement shall be deemed null and void. 
 (d) Choice of Law. The validity, interpretation, construction and performance of this Agreement shall be governed by the laws of the State of California without reference to conflict of laws provisions.

 (e) Severability. If any term or provision of this Agreement or the application thereof to any circumstance shall, in any
jurisdiction and to any extent, be invalid or unenforceable, such term or provision shall be ineffective as to such jurisdiction to the extent of such invalidity or unenforceability without invalidating or rendering unenforceable the remaining terms
and provisions of this Agreement or the application of such terms and provisions to circumstances other than those as to which it is held invalid or unenforceable, and a suitable and 

  

 -6- 

 
equitable term or provision shall be substituted therefore to carry out, insofar as may be valid and enforceable, the intent and purpose of the invalid or
unenforceable term or provision. 
 (f) Arbitration. Any dispute or controversy arising under or in connection with this
Agreement may be settled at the option of either party by binding arbitration in the County of Alameda, California, in accordance with the rules of the American Arbitration Association then in effect before a single arbitrator. The judgment may be
entered on the arbitrator’s award in any court having jurisdiction. Punitive damages shall not be awarded. 
 (g) Legal Fees and
Expenses. The parties shall each bear their own expenses, legal fees, and other fees incurred in connection with this Agreement. This means the Company pays its own legal fees in connection with this Agreement and the Employee is responsible
for his own legal fees in connection with this Agreement. However, the arbitrator may award legal fees and expenses in connection with any arbitration as deemed appropriate. 
 (h) No Assignment of Benefits. The rights of any person to payments or benefits under this Agreement shall not be made subject to option or
assignment, either by voluntary or involuntary assignment or by operation of law, including (without limitation) bankruptcy, garnishment, attachment, or other creditor’s process, and any action in violation of this Section 9(h) shall be
void. 
 (i) Employment Taxes. All payments made pursuant to this Agreement will be subject to withholding of applicable income
and employment taxes. 
 (j) Assignment by Company. The Company may assign its rights under this Agreement to an affiliate, and
an affiliate may assign its rights under this Agreement to another affiliate of the Company or to the Company; provided, however, that such assignee is the employer of the Employee. In the case of any such assignment, the term “Company”
when used in a section of this Agreement shall mean the corporation that actually employs the Employee except that the term “Company” shall continue to mean Dynavax Technologies Corporation with regard to the definition of a Change of
Control. 
 (k) Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed an original, but
all of which together will constitute one and the same instrument.
