 Exhibit 10.75 
 DYNAVAX TECHNOLOGIES CORPORATION 
 AMENDED AND RESTATED

 MANAGEMENT CONTINUITY AND SEVERANCE AGREEMENT 

This Amended and Restated Management Continuity and Severance Agreement (the “Agreement”) is dated as of
October 31, 2012 (the “New Effective Date”), by and between J. Tyler Martin (“Employee”), and Dynavax Technologies Corporation, a Delaware corporation (the “Company” or
“Dynavax”). This Agreement supersedes and replaces in its entirety the Amended and Restated Management Continuity and Severance Agreement, dated as of November 12, 2010, between the Company and Employee. 

RECITALS 
 A.          The Company is currently in the process of identifying a new Chief Executive Officer and obtaining FDA review and approval of its BLA
filing for the Company’s lead product, and the Employee is an essential participant in the preparation and presentation to the FDA. 
 B.          The Company’s Board of Directors believes it is in the best interests of the Company and its stockholders 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 termination of Employee’s employment or a Change of Control during this critical period for the Company, which benefits are intended to provide Employee with encouragement to Employee
to remain with the Company. 
 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.	Employment. 

 (a)       Employee is currently serving as the President and Chief Medical Officer of the Company, with such duties and responsibilities as the Company’s
Board of Directors may designate. The Employee shall perform services principally at the Company’s headquarters located in Berkeley, California. In addition, Employee shall make such business trips to such places as may be necessary or
advisable for the efficient operations of the Company. During his 

  

					
	T. Martin Continuity Agreement	 	-1-	 	

 
employment with the Company, Employee will devote Employee’s best efforts and substantially all of Employee’s business time and attention to the business of the Company. 

(b)       Employee shall be paid a base salary (the “Base
Salary”) at the annual rate of $412,000 (effective as of January 1, 2012), payable in bi-weekly installments, consistent with the Company’s payroll practices. Employee shall also be eligible to earn an annual bonus (the
“Bonus”) of up to 55% of such amount (that is, $226,600), with the actual Bonus earned determined in the sole discretion of the Company’s Board of Directors based upon achievement of such milestones as to which the
Company’s Board of Directors and Employee shall mutually agree. 

(c)       Employee has or will receive certain equity awards that will be
governed by the terms of such awards; provided that Employee is eligible to earn and have fully vested certain payment amounts and is eligible for acceleration of vesting in full of all of his time-based vesting equity awards granted as of the New
Effective Date as set forth in more detail in Section 2(d) (the “Acceleration Bonus”). To earn the Acceleration Bonus, Employee must remain in continued employment in good standing through the later of March 1, 2013 or the
actual PDUFA action date for Heplisav (such later date, the “Acceleration Date”), which Acceleration Date shall in any event occur not later than June 1, 2013. If Employee does not remain in continued employment with the
Company through the Acceleration Date, no amount of the Acceleration Bonus will be earned or vested, except that, if applicable, amounts payable in accordance with Section 2(c) shall be unaffected. For clarity, Section 2(d) of this
Agreement shall not apply to any equity awards granted after the New Effective Date. 

(d)       Upon submission of itemized expense statements in the manner
specified by the Company, Employee shall be entitled to prompt reimbursement for reasonable business travel and other reasonable business expenses duly incurred by Employee in the performance of his duties. 

(e)       Employee shall be eligible to participate in the Company’s
medical and dental insurance plans, life and disability insurance plans, and retirement plans, if any, as in effect from time to time and made available to other officers of the Company, in each case pursuant to the terms and conditions of such
plans. 
 (f)       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 prior to the Acceleration Date for any reason other than termination by the Company without Cause (in which event his compensation shall be 

  

					
	T. Martin Continuity Agreement	 	-2-	 	

 
payable in accordance with Section 2(c) below), Employee shall not 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 date that all obligations of the parties
hereunder have been satisfied. 
  

	 	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; provided that if such termination for Cause occurs after the Acceleration Date, Employee’s Vested Separation Benefits (as defined in Section 2(d)) shall be unaffected by and
immediately due and owing upon such termination. Employee will receive payment for all accrued but unpaid salary and vacation as of the date of Employee’s termination of employment, and Employee’s benefits will continue 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 applicable law. If the Company proposes to terminate the Employee’s employment for Cause, the Company
shall provide written notice to the Employee setting forth the reasons for such termination and giving the Employee an opportunity to respond and to cure (to the extent such reason is capable of cure) prior to the effective date of termination,
which shall be not less than thirty (30) calendar days after the Employee’s receipt of such notice. 

(b)       Other Terminations.  If Employee’s employment
ends as a result of death or disability, or due to Employee’s resignation that is not a Qualifying Separation (as defined in Section 2(d)), then Employee shall not be entitled to receive payment of any severance benefits; provided that if
such termination occurs after the Acceleration Date, Employee’s Vested Separation Benefits (as defined in Section 2(d)) shall be unaffected by and immediately due and owing upon such termination. Employee will receive payment for accrued
but unpaid salary and vacation 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 applicable law. 

(c)       Termination Without Cause.    In the
event the Company terminates Employee’s employment without Cause at any time prior to the Acceleration Date, then subject to Employee executing a general release in favor of the Company, in a form acceptable to the Company (the
“Release”), and allowing such Release to become effective not later than 60 days following Employee’s Separation from Service, Employee shall be entitled to receive the following severance benefits (the “Severance
Benefits”): 

  

					
	T. Martin Continuity Agreement	 	-3-	 	

 (i)        a lump-sum cash
severance payment equal to 24 months of Employee’s then-current Base Salary, subject to applicable tax withholdings, paid on the 60th day following Employee’s Separation from Service, except as provided in Section 9(l) below; 

(ii)       a lump-sum cash severance payment equal to 200% of Employee’s target
Bonus for the year of termination, subject to applicable tax withholdings, paid on the 60th day following Employee’s Separation from Service, except as provided in Section 9(l) below; 
 (iii)      all of Employee’s then-outstanding time-based vesting stock option awards shall automatically accelerate and fully vest as of immediately prior to the
effective time Employee’s termination and Employee shall, with respect to such stock options, have until the earlier of (A) the third anniversary of the termination of Employee’s continuous service (as defined under the applicable
stock option award agreement) and (B) the original term of each such option (subject to any earlier termination in the event of a Corporate Transaction as provided under the applicable stock plan) in which to exercise his vested options, but in
no event will Employee’s options be exercisable beyond their original full term; and 

(iv)      if Employee is participating in the Company’s employee group health
insurance plans on the effective date of termination, and timely elects and remains eligible for continued coverage under COBRA, or, if applicable, state or local insurance laws, the Company shall pay to Employee, on the first day of each month, a
cash payment equal to the applicable COBRA premiums for that month (including premiums for Employee and his eligible dependents who have elected and remain enrolled in such COBRA coverage), subject to applicable tax withholdings (such amount, the
“Special Cash Payment”), for a number of months equal to the lesser of (A) the duration of the period in which Employee and his eligible dependents are eligible for and enrolled in such COBRA coverage (and not otherwise covered
by another employer’s group health plan) and (B) 24 months. Employee may, but is not obligated to, use such Special Cash Payment toward the cost of COBRA premiums. On the 60th day following Employee’s Separation From Service, the Company will make the first payment to Employee under this
Section 2(c)(iv), in a lump sum, equal to the aggregate Special Cash Payments that the Company would have paid to Employee through such date had the Special Cash Payments commenced on the first day of the first month following the effective
date of termination through such 60th day, with the
balance of the Special Cash Payments paid thereafter on the schedule described above. In the event Employee becomes covered under another employer’s group health plan or otherwise ceases to be eligible for COBRA during the period provided in
this Section 2(c)(iv), Employee must immediately notify the Company of such event and the Company shall cease payment of the Special Cash Payments and shall have no further obligations under this Section 2(c)(iv). 

  

					
	T. Martin Continuity Agreement	 	-4-	 	

 (v)       For clarity, if Employee is
terminated without Cause after the Acceleration Date, no Severance Benefits shall be payable, but Employee shall be entitled to the Vested Separation Benefits to the extent not previously paid or vested. 

(d)       Qualifying Separation. If Employee resigns for any reason
prior to the Acceleration Date, Employee will not be entitled to any Severance Benefits or Vested Separation Benefits from the Company. If Employee is terminated or resigns for any reason following the Acceleration Date, and provided Employee has
not, prior to the resignation or termination date, accepted the position as Chief Executive Officer of the Company (such a termination or resignation, a “Qualifying Separation”), then subject to Employee executing a Release, and
allowing such Release to become effective not later than 60 days following Employee’s Separation from Service, Employee shall be entitled to receive the following severance benefits (the “Vested Separation Benefits”):

 (i)        a lump-sum cash severance payment equal to 24 months of
Employee’s then-current Base Salary, subject to applicable tax withholdings, paid on the 60th day following Employee’s Separation from Service, except as provided in Section 9(l) below; 
 (ii)       a lump-sum cash severance payment equal to 200% of Employee’s target Bonus for the year of termination, subject to applicable tax withholdings, paid on
the 60th day following Employee’s Separation from
Service, except as provided in Section 9(l) below; 
 (iii)      to the
extent not previously amended, amendment of any time-based vesting equity awards granted as of the New Effective Date to provide for full acceleration of vesting and, with respect to any vested stock options granted as of the New Effective Date,
extension of the Employee’s exercise period to the earlier of (A) the third anniversary of the termination of Employee’s continuous service (as defined under the applicable option award agreement) and (B) the original term of
each such option (subject to any earlier termination in the event of a Corporate Transaction as provided under the applicable stock plan), but in no event will Employee’s options be exercisable beyond their original full term; and 

(iv)      if Employee is participating in the Company’s employee group health
insurance plans on the effective date of termination, and timely elects and remains eligible for continued coverage under COBRA, or, if applicable, state or local insurance laws, the Company shall pay to Employee, on the first day of each month, a
cash payment equal to the applicable COBRA premiums for that month (including premiums for Employee and his eligible dependents who have elected and remain enrolled in such COBRA coverage), subject to applicable tax withholdings (such amount, the
“Special Cash Payment”), for a number of months equal to the lesser of (A) the duration of the period in which Employee and his eligible 

  

					
	T. Martin Continuity Agreement	 	-5-	 	

 
dependents are eligible for and enrolled in such COBRA coverage (and not otherwise covered by another employer’s group health plan) and (B) 24 months. Employee may, but is not obligated
to, use such Special Cash Payment toward the cost of COBRA premiums. On the 60th day following Employee’s Separation From Service, the Company will make the first payment to Employee under this Section 2(d)(iv), in a lump sum, equal to the aggregate Special Cash Payments
that the Company would have paid to Employee through such date had the Special Cash Payments commenced on the first day of the first month following the effective date of termination through such 60th day, with the balance of the Special Cash Payments paid thereafter
on the schedule described above. In the event Employee becomes covered under another employer’s group health plan or otherwise ceases to be eligible for COBRA during the period provided in this Section 2(d)(iv), Employee must immediately
notify the Company of such event and the Company shall cease payment of the Special Cash Payments and shall have no further obligations under this Section 2(d)(iv). 

(e)       For clarity, following vesting and payment of Severance Benefits
under Section 2(c) or vesting of the Vested Separation Benefits (it being understood that the Company stands prepared to make payment of the Vested Separation Benefits from and after the time of vesting) as set forth in Section 2(d), in
each case if applicable, the Company shall have no further obligation to make any payments or to provide any additional benefits to Employee under this Agreement, including any severance benefits, except for any salary and/or bonus that may be due
to Employee in connection with his regular employment under Section 1(b). 
  

	 	3.	Benefits upon a Change of Control. 

 (a)       In the event of a Change of Control prior to the Acceleration Date, and subject to Employee’s continued service with the Company through the time
immediately prior to the closing of such Change of Control and termination of employment by the Company or successor entity without Cause resulting in a Separation from Service, and subject to Employee executing a Release, and allowing such Release
to become effective not later than the effective date of the Change of Control, the Severance Benefits pursuant to Section 2(c) will not be forfeited on the Change of Control, and shall be payable, and all of Employee’s then-outstanding
time-based vesting equity awards shall automatically accelerate and fully vest, as and when provided in Section 2(c) subject to the conditions set forth in Section 2(c). 

(b)       In the event of a Change of Control on or after the Acceleration
Date, to the extent not previously triggered, the Vested Separation Benefits will not be forfeited on the Change of Control, but shall become payable and vested as and when provided in Section 2(d),, subject to the conditions set forth in
Section 2(d), including Employee’s continued service with the Company through the time immediately prior to the closing of such Change of Control and 

  

					
	T. Martin Continuity Agreement	 	-6-	 	

 
subsequent Qualifying Termination, and subject to Employee executing a Release, and allowing such Release to become effective not later than the effective date of the Change of Control.

 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, provided such transaction
is also a “change in the ownership or effective control of” the Company or “a change in the ownership of a substantial portion of the assets of” the Company as determined under Treasury Regulations Section 1.409A-3(i)(5)
(without regard to any alternative definition thereunder): 

     (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.  In the event of (x) a merger, acquisition or consolidation of the Company, whether or not approved by the Board, other than a merger, acquisition 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; (y) the stockholders of the Company approve a plan of complete liquidation, dissolution or similar extraordinary transaction of the Company; or
(z) 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 reasonably likely to result in substantial and material damage to the
Company or its subsidiaries taken as a whole; (ii) repeated unexplained or unjustified absence from the Company; (iii) a material and willful violation of any federal or state law (other than misdemeanor traffic violations) that has
resulted or is reasonably likely to result in substantial and material damage to the Company or its subsidiaries taken as a whole; (iv) commission of any act of fraud with respect to the Company that is material and significant; 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. 

  

					
	T. Martin Continuity Agreement	 	-7-	 	

 (c)       Separation from
Service  shall mean Employee’s “separation from service” within the meaning of Treasury Regulation Section 1.409A-1(h) without regard to any permissible alternative definition thereunder. 

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 from the Company or otherwise in connection with a Change of Control or other similar transaction
(“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 ((x) or (y)), after taking into account all applicable federal,
state and local employment taxes, income taxes, 

  

					
	T. Martin Continuity Agreement	 	-8-	 	

 
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 Reduced Amount will give rise to the greater after tax benefit, the reduction in the Payments shall occur in the following order: (a) reduction of cash payments; (b) cancellation of
accelerated vesting of equity awards other than stock options; (c) cancellation of accelerated vesting of stock options; and (d) reduction of other benefits paid to Employee. Within any such category of payments and benefits (that is, (a),
(b), (c) or (d)), a reduction shall occur first with respect to amounts that are not “deferred compensation” within the meaning of Section 409A and then with respect to amounts that are. In the event that acceleration of
compensation from Employee’s equity awards is to be reduced, such acceleration of vesting shall be canceled, subject to the immediately preceding sentence, in the reverse order of the date of grant. 

(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 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 reasonably 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 (except as expressly provided in Section 2(c)(ii) and Section 3(b)(ii)).

 (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 

  

					
	T. Martin Continuity Agreement	 	-9-	 	

 
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. This Agreement supersedes any agreement of the same or similar 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; provided, that all of Employee’s stock options issued prior to or
after the date hereof shall remain in effect in accordance with their terms, except to the extent specifically modified hereby. The Agreement may not be modified or amended in any way except by a written agreement executed by Employee and a duly
authorized member of the board of directors. For the avoidance of doubt, nothing in this Agreement supersedes or replaces the terms of the Proprietary Information and Inventions Assignment Agreement between the Company and Employee, the terms of
which remain in full force and effect. 
 (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 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.   To ensure the timely and
economical resolution of disputes that may arise in connection with Employee’s employment with the Company, Employee and the Company agree that any and all disputes, claims, or causes of action arising from or relating to the enforcement,
breach, performance, negotiation, execution, or interpretation of this Agreement, Employee’s employment, or the termination of Employee’s employment, including but not limited to statutory claims, shall be resolved to the fullest extent
permitted by law by final, binding and confidential arbitration, by a single arbitrator, in San Jose, California, 

  

					
	T. Martin Continuity Agreement	 	-10-	 	

 
conducted by JAMS, Inc. (“JAMS”) under the then applicable JAMS rules. By agreeing to this arbitration procedure, both Employee and the Company waive the right to resolve any
such dispute through a trial by jury or judge or administrative proceeding. The Company acknowledges that Employee will have the right to be represented by legal counsel at any arbitration proceeding. The arbitrator shall: (a) have the
authority to compel adequate discovery for the resolution of the dispute and to award such relief as would otherwise be permitted by law; and (b) issue a written arbitration decision, to include the arbitrator’s essential findings and
conclusions and a statement of the award. The arbitrator shall be authorized to award any or all remedies that Employee or the Company would be entitled to seek in a court of law. The Company shall pay all JAMS’ arbitration fees in excess of
the amount of court fees that would be required of the Employee if the dispute were decided in a court of law. Nothing in this Agreement is intended to prevent either Employee or the Company from obtaining injunctive relief in court to prevent
irreparable harm pending the conclusion of any such arbitration. Any awards or orders in such arbitrations may be entered and enforced as judgments in the federal and state courts of any competent jurisdiction. 

(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. 
 (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. 

  

					
	T. Martin Continuity Agreement	 	-11-	 	

(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. 
 (l)        Application of Section 409A.    It is intended that each installment of payments and benefits provided for in this
Agreement is a separate “payment” for purposes of Treasury Regulation Section 1.409A-2(b)(2)(i). To the extent permissible, the payments and benefits set forth in this Agreement will be administered in a manner that is consistent with
the exceptions from the application of Section 409A of the Code and the regulations and other guidance thereunder and any state law of similar effect (collectively, “Section 409A”), including but not limited to the
exceptions under Treasury Regulation Sections 1.409A-1(b)(4), 1.409A-1(b)(5), and 1.409A-1(b)(9), and this Agreement will be construed in accordance therewith to the maximum extent permitted by law. To the extent any payments and benefits provided
under this Agreement are not so exempt and constitute “deferred compensation” within the meaning of Section 409A, this Agreement will be construed in a manner that is compliant with Section 409A to the maximum extent permitted by
law. If Employee is, on his Separation from Service, a “specified employee” of the Company or any successor entity thereto, as such term is defined in Section 409A(a)(2)(B)(i) of the Code, then, solely to the extent necessary to avoid
the incurrence of the adverse personal tax consequences under Section 409A, the timing of the payments and delivery of the benefits that become due on such a Separation from Service shall be delayed until the earliest to occur of: (a) the
date that is six months and one day after Employee’s Separation from Service, (b) the date of Employee’s death or (c) such earlier date as is permitted under Section 409A (such applicable date, the “Specified
Employee Initial Payment Date”). On the Specified Employee Initial Payment Date, the Company (or the successor entity thereto, as applicable) shall (i) pay to Employee a lump sum amount equal to the sum of the payments and benefits
that Employee would otherwise have received through the Specified Employee Initial Payment Date if the commencement of the payment of such amounts had not been so delayed for compliance with Section 409A and (ii) commence paying the
balance of the payments and benefits thereafter in accordance with the applicable payment schedules set forth in this Agreement.

 Exhibit 10.20 
 SEPARATION AGREEMENT 
 This Separation Agreement (this
“Agreement”) is made by and between David Oppenheimer (“Employee”) and ServiceSource International, Inc. (the “Company”) (collectively referred to as the “Parties” or individually
referred to as a “Party”). Capitalized Terms used but not defined herein shall have the meaning set forth in the Employment Agreement (as defined below). 
 WHEREAS, Employee signed that certain Employment and Confidential Information Agreement with the Company on July 7, 2010 (the “Employment Agreement”); 

WHEREAS, the Company and Employee have arrived at a mutual agreement that Employee’s employment with the Company will terminate
effective as of the date on which the Company’s Annual Report on Form 10-K is completed and executed by Employee, or such other later date as may be mutually agreed by Employee and Company (the “Employment Separation Date”);
and 
 NOW, THEREFORE, in consideration of the mutual promises made herein, the Company and Employee hereby agree as follows:

 1. Separation. Employee’s last day of employment with the Company and Employee’s employment termination date
shall be the Employment Separation Date. As of the Employment Separation Date, Employee shall resign from any and all offices Employee has with the Company. Employee shall execute such additional documents as requested by the Company to evidence the
foregoing. The Parties agree that nothing herein or in the Employment Agreement shall preclude Employee from (a) accepting employment with an employer other than the Company or (b) performing consulting services for another employer prior
to the Employment Separation Date, provided, in each case, that such activity does not constitute a Competitive Activity for purposes of the Employment Agreement or materially interfere with Employee’s obligation to diligently perform
his duties as set forth in Section 2 of the Employment Agreement through the Employment Separation Date as his primary employment obligation. 
 2. Severance Payments. Subject to the Employee’s execution of a general release of claims against the Company in the form attached hereto as Schedule A on his Employment Separation Date
(the “Release”), and such Release becoming effective and irrevocable no later than the date that is sixty (60) days after the Employment Separation Date (the “Release Deadline”), Employee shall be entitled to
receive from the Company a lump sum payment in cash equal to (1) six months of his then-current base salary, (2) 50% of Employee’s target annual bonus, and (3) an amount equal, on an after tax basis, to the aggregate COBRA
premiums that Employee would pay for the twelve months following the Employment Separation Date if Employee timely elected COBRA (together the “Severance Payment”). The Severance Payment shall be payable on the Release Deadline. If
the Release does not become effective and irrevocable on or prior to the Release Deadline, Employee shall not be entitled to receive the Severance Payment. 

 3. Accrued Amounts. Following the Employment Separation Date, the Company will pay
Employee all Accrued Amounts (as defined below), subject to payroll deductions and required withholdings. “Accrued Amounts” means (a) any accrued but unpaid base salary and vacation through the Employment Separation Date paid
in accordance with Company’s normal payroll practices, (b) any unreimbursed business expenses incurred prior to the Employment Separation Date paid in accordance with Company policies, and (c) to the extent not paid on or prior to the
Employment Separation Date, any earned but unpaid annual bonus in respect of the Company’s fiscal year 2012, to the extent that applicable performance targets are achieved, payable when annual bonuses in respect of the Company’s fiscal
year 2012 are paid to the Company’s executive officers generally, in each case subject to applicable tax withholding. 
 4.
Stock Options. The Parties agree that any options to purchase common stock of the Company granted to Employee pursuant to the terms of the Company’s 2008 Share Option Plan (the “2008 Plan”) and 2011 Equity Incentive Plan
(together with the 2008 Plan, the “Stock Plans”), that are outstanding as of the Employment Separation Date (“Options”) shall, to the extent vested on or prior to the Employment Separation Date, remain outstanding
and exercisable until the earlier of (a) the date that is nine (9) months after the Employment Separation Date and (b) the end of the original maximum term of such Options under the Stock Plans and the option agreements pursuant to
which they were granted (the “Option Agreements”). For the avoidance of doubt, any Options that are outstanding and unvested as of the Employment Separation Date shall terminate and be forfeited as of the Employment Separation Date.
The Options shall otherwise continue to be subject to all other terms of the Stock Plans and the Option Agreements. 
 5.
Benefits. Except as set forth in Section 4 above, Employee’s participation in all other benefits and incidents of employment, and the accrual of bonuses, vacation, and paid time off, shall cease as of the Employment Separation Date.

 6. Payment of Salary and Receipt of All Benefits. Employee acknowledges and represents that, other than the
consideration set forth in this Agreement and any benefits or compensation that may accrue by virtue of Employee’s employment with the Company between the date of this Agreement and the Employment Separation Date, the Company has paid or
provided all salary, wages, bonuses, accrued vacation/paid time off, premiums, leaves, housing allowances, relocation costs, interest, severance, outplacement costs, fees, reimbursable expenses, commissions, stock, stock options, vesting, and any
and all other benefits and compensation due to Employee through the date hereof. 
 7. Trade Secrets and Confidential
Information/Company Property. Employee reaffirms and agrees to observe and abide by the terms of the Employment Agreement, specifically including the provisions therein regarding nondisclosure of the Company’s Proprietary and Confidential
Information (as defined in the Employment Agreement) and nonsolicitation of Company clients and employees. Employee agrees that, upon the Employment Separation Date, Employee shall return all documents and other items provided to Employee by the
Company, developed or obtained by Employee in connection with his employment with the Company, or otherwise belonging to the Company, including all property in electronic form and all copies of Proprietary and Confidential Information.

 8. No Admission of Liability. Company and Employee understand and acknowledge that
this Agreement and the Release constitute a compromise and settlement of any and all actual or potential disputed claims by either party. No action taken by either party, either previously or in connection with this Agreement or the Release, shall
be deemed or construed to be (a) an admission of the truth or falsity of any actual or potential claims or (b) an acknowledgment or admission by the party of any fault or liability whatsoever to the other party, or to any third party.

 9. Costs. The Parties shall each bear their own costs, attorneys’ fees, and other fees incurred in connection
with the preparation of this Agreement. 
 10. Disputes. This Agreement shall be governed by California law, without
regard to its principles of conflicts of laws. Any dispute arising from this Agreement shall be subject to the exclusive jurisdiction of state and federal courts located in the Northern District of California. The prevailing party in any such
dispute shall recover its reasonable attorneys’ fees and costs from the losing party, including any fees or costs arising from an appeal. 
 11. Authority. The Company represents and warrants that the undersigned has the authority to act on behalf of the Company and to bind the Company and all who may claim through it to the terms and
conditions of this Agreement. Employee represents and warrants that he has the capacity to act on his own behalf and on behalf of all who might claim through him to bind them to the terms and conditions of this Agreement. Each Party warrants and
represents that there are no liens or claims of lien or assignments in law or equity or otherwise of or against any of the claims or causes of action released herein. 
 12. No Representations. Employee represents that he has had an opportunity to consult with an attorney, and has carefully read and understands the scope and effect of the provisions of this
Agreement. Employee has not relied upon any representations or statements made by the Company that are not specifically set forth in this Agreement. 
 13. Severability. In the event that any provision or any portion of any provision hereof or any surviving agreement made a part hereof becomes or is declared by a court of competent jurisdiction or
arbitrator to be illegal, unenforceable, or void, this Agreement shall continue in full force and effect without said provision or portion of provision. 
 14. Entire Agreement. This Agreement represents the entire agreement and understanding between the Company and Employee concerning the subject matter of this Agreement and Employee’s
employment with and separation from the Company and the events leading thereto and associated therewith, and supersedes and replaces any and all prior agreements and understandings concerning the subject matter of this Agreement and Employee’s
relationship with the Company, with the exception of the Employment Agreement and the Option Agreements. 
 15. No Oral
Modification. This Agreement may only be amended in a writing signed by Employee and the Company’s Chief Executive Officer.

 16. Section 409A. It is intended that this Agreement comply with, or be exempt
from, Code Section 409A and the final regulations and official guidance thereunder (“Section 409A”) and any ambiguities herein will be interpreted to so comply and/or be exempt from Section 409A. Each payment and
benefit to be paid or provided under this Agreement is intended to constitute a series of separate payments for purposes of Section 1.409A-2(b)(2) of the Treasury Regulations. The Company and Employee will work together in good faith to
consider either (i) amendments to this Agreement; or (ii) revisions to this Agreement with respect to the payment of any awards, which are necessary or appropriate to avoid imposition of any additional tax or income recognition prior to
the actual payment to Employee under Section 409A. In no event will the Company reimburse Employee for any taxes that may be imposed on Employee as a result of Section 409A. 

17. Counterparts. This Agreement may be executed in counterparts and by facsimile, and each counterpart and facsimile shall have
the same force and effect as an original and shall constitute an effective, binding agreement on the part of each of the undersigned. 
 18. Voluntary Execution of Agreement. Employee understands and agrees that he executed this Agreement voluntarily, without any duress or undue influence on the part or behalf of the Company or any
third party. Employee acknowledges that: 
  

	 	(a)	he has read this Agreement; 

  

	 	(b)	he has been represented in the preparation, negotiation, and execution of this Agreement by legal counsel of his own choice or has elected not to retain legal counsel;

 SCHEDULE A 

FORM OF RELEASE 
 In exchange for the consideration provided to me by the Separation Agreement entered into with ServiceSource International, Inc. (the “Company”) on December 5, 2012 (the
“Separation Agreement”) that I am not otherwise entitled to receive, and subject to the Company’s compliance with its post-termination obligations to me as set forth in the Separation Agreement, I hereby generally and
completely release the Company and its directors, officers, employees, shareholders, partners, agents, attorneys, predecessors, successors, parent and subsidiary entities, insurers, affiliates, and assigns from any and all claims, liabilities and
obligations, both known and unknown, that arise out of or are in any way related to events, acts, conduct, or omissions occurring prior to my signing this release agreement. This general release includes, but is not limited to: (1) all claims
arising out of or in any way related to my employment with the Company or the termination of that employment; (2) all claims related to my compensation or benefits from the Company, including salary, bonuses, commissions, vacation pay, expense
reimbursements, severance pay, fringe benefits, stock, stock options, or any other ownership interests in the Company; (3) all claims for breach of contract, wrongful termination, and breach of the implied covenant of good faith and fair
dealing; (4) all tort claims, including claims for fraud, defamation, emotional distress, and discharge in violation of public policy; and (5) all federal, state, and local statutory claims, including claims for discrimination, harassment,
retaliation, attorneys’ fees, or other claims arising under the federal Civil Rights Act of 1964 (as amended), the federal Americans with Disabilities Act of 1990, the federal Age Discrimination in Employment Act of 1967 (as amended)
(“ADEA”), the Family and Medical Leave Act; the Employee Retirement Income Security Act; California Fair Employment and Housing Act (as amended ), any state labor code; the Equal Pay Act, of 1963, as amended. 

SECTION 1542 WAIVER. I hereby acknowledge that I have read and understand Section 1542 of the Civil Code
of the State of California, which reads as follows: 
 A general release does not extend to claims which the creditor does not
know or suspect to exist in his favor at the time of executing the release, which if known by him must have materially affected his settlement with the debtor. 
 I hereby expressly waive and relinquish all rights and benefits under that section and any law or legal principle of similar effect in any jurisdiction with respect to the release of any unknown or
unsuspected claims I may have against the Company, its affiliates, and the entities and persons specified above. 
 ADEA Waiver and
Release. I acknowledge that I am knowingly and voluntarily waiving and releasing any rights I may have under the ADEA, as amended. I also acknowledge that the consideration given for the waiver and release in the preceding paragraph hereof is in
addition to anything of value to which I was already entitled. I further acknowledge that I have been advised by this writing, as required by the ADEA, that: (a) my waiver and release does not apply

to any rights or claims that may arise after the execution date of this release agreement; (b) I have been advised that I have the right to consult with an attorney prior to executing this
release agreement; (c) I have been given twenty-one (21) days to consider this release agreement; (d) I have seven (7) days following the execution of this release agreement by the parties to revoke the release agreement; and
(e) this release agreement will not be effective until the date upon which the revocation period has expired, which will be the eighth day after I have executed this release agreement, provided that the Company has also executed this release
agreement by that date (the “Effective Date”). I acknowledge and agree that revocation by me of the ADEA waiver and release is not effective to revoke my waiver or release of any other claims pursuant to this release
agreement.
