transferable by surrender hereof at the principal office of the Company, duly endorsed or accompanied by a written instrument of transfer duly executed by the registered holder of this Security or by any other method permitted by the Purchase

 2. All payments hereunder shall be applied in the order provided for in the Purchase Agreement. Whenever any payment hereunder
shall be stated to be due, or whenever any return payment date or any other date specified hereunder would otherwise occur, on a day other than a Business Day, then such payment shall be made, and such return payment date or other date shall occur,
on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of returns hereunder.

(each, a “Dispute”) arising out of or relating to this Security, the Purchase Agreement or any Related Documents shall be finally resolved by confidential binding arbitration in San Francisco County, California as the sole and
exclusive method of resolving such dispute, controversy or claim. Any Dispute shall be settled by arbitration under the rules then in effect of JAMS/Endispute conducted by a single arbitrator reasonably acceptable to the parties. The arbitrator

Agreement and the Related Documents without prejudice to a final adjustment in accordance with the award. 
 6. Notwithstanding any provision
of this Security to the contrary, any payments hereunder deemed to be interest shall not exceed the maximum rate permitted by applicable law. To the extent that any interest otherwise paid or payable by the Company to the Holder shall have been
finally adjudicated to exceed the maximum amount permitted by applicable law, such interest shall be retroactively deemed to have been a required repayment of principal (and any such amount paid in excess of the outstanding principal amount shall be
promptly returned to the Company).

this Security and the other Securities may be waived (either generally or in a particular instance and either retroactively or prospectively), only in accordance with the terms of the Purchase Agreement. Any such amendment or waiver shall be
effective only for the specific instance and for the specific purpose for which given. 
 8. No remedy herein conferred upon the Holder is
intended to be exclusive of any other remedy, and each and every such remedy shall be cumulative and shall be in addition to every right or other remedy now or hereafter existing at law or in equity or by statute or otherwise. 
 9. No course of dealing between the Company and the Holder or any delay on the part of the Holder in exercising any rights or remedies shall operate as a
waiver of any such right or remedy of the Holder. 
 10. This Security shall be binding on and inure to the benefit of and be enforceable by
the Company, the Holder and their respective successors and assigns. The Company may not assign, transfer, hypothecate or otherwise convey its rights, benefits, obligations or duties hereunder without the prior express written consent of the
Majority Investors. Any such purported assignment, transfer, hypothecation or other conveyance by the Company without the prior express written consent of the Majority Investors shall be void.

 11. Whenever possible, each provision of this Security shall be interpreted in such manner as to be
effective and valid under all applicable laws and regulations. If, however, any provision of this Security shall be prohibited by or invalid under any such law or regulation in any jurisdiction, it shall, as to such jurisdiction, be deemed modified
to conform to the minimum requirements of such law or regulation, or, if for any reason it is not deemed so modified, it shall be ineffective and invalid only to the extent of such prohibition or invalidity without affecting the remaining provisions
of this Security, or the validity or effectiveness of such provision in any other jurisdiction. 
 12. This Security is issued pursuant to
the Purchase Agreement and in connection with the Security Agreement, the Pledge Agreement and the other Related Documents. Material terms applicable to this Security are set forth in the Purchase Agreement, the Security Agreement, the Pledge
Agreement and the other Related Documents. This Security shall be interpreted in a manner to give full effect to its provisions and the provisions of the Purchase Agreement, the Security Agreement, the Pledge Agreement and the other Related
Documents.

counsel (including the allocated costs of internal counsel), in connection with: (i) any amendments, modifications or waivers of the terms hereof or of the Purchase Agreement or of any other Related Documents; (ii) the protection or

 ANESIVA, INC. 
 AMENDED AND RESTATED EXECUTIVE CHANGE IN CONTROL AND 
 SEVERANCE BENEFIT PLAN 
 SECTION 1.
INTRODUCTION. 
 The Anesiva, Inc. Amended and Restated Executive Change in Control and Severance Benefit Plan (the
“Plan”) has been established effective July 29, 2005 (the “Effective Date”) and amended March 31, 2008 and January 20, 2009. The purpose of the Plan is to provide for the payment to
certain eligible executive employees of Anesiva, Inc. (the “Company”) of certain benefits in the event of a Change in Control (as such term is defined below) as well as severance benefits in the event that such employees are
subject to qualifying employment terminations in connection with a Change in Control. This Plan shall supersede any change in control or severance benefit plan, policy, or practice previously maintained by the Company, other than an individually
negotiated contract or agreement with the Company relating to change in control or severance benefits that is in effect on the effective date of a Change in Control or an employee’s termination date which provides benefits that the Plan
Administrator (as such term is defined below), in its sole discretion, determines to be of greater value than the benefits provided for in this Plan, in which case such employee’s change in control benefit or severance benefit, if any, shall be
governed by the terms of such individually negotiated employment contract or agreement and shall be governed by this Plan only to the extent that the reduction pursuant to Section 5(b) below does not entirely eliminate benefits under this Plan.
This Plan shall not supersede any benefit provided pursuant to an equity compensation plan or program maintained by the Company. This document also constitutes the Summary Plan Description for the Plan. 
 SECTION 2. DEFINITIONS. 
 For purposes
of the Plan, the following terms are defined as follows: 
 (a) “Base Salary” means the Eligible
Employee’s annual base pay (excluding incentive pay, premium pay, commissions, overtime, bonuses and other forms of variable compensation), at the rate in effect during the last regularly scheduled payroll period immediately preceding the date
of the Eligible Employee’s Covered Termination.

Inc.

the sale, transfer, assignment or other conveyance or disposition of any securities or any rights to securities of the Company by any holder or holders thereof representing in the aggregate more than fifty percent (50%) of the issued and
outstanding voting securities of the Company; 
  

 1 

 (ii) a merger, consolidation, reorganization, recapitalization or share exchange

together with cash, property or other securities), cash, property or securities of the resulting or surviving entity and as a result thereof persons who were holders of voting securities of the Company immediately prior to such transaction hold less
than fifty percent (50%) of the issued and outstanding capital stock of the resulting or surviving entity entitled to vote in the election of directors, managers or similar governing body or otherwise; 
 (iii) a sale, transfer, exclusive license, exclusive partnering arrangement or other disposition in a single transaction or series

as determined in good faith by the Board, of all other property paid or payable directly or indirectly by a third party or the Company to the Company’s stockholders (or to the Company in the case of a Change in Control structured as an asset
sale, exclusive license or similar transaction) in consideration for their shares or any debt or equity-linked securities (e.g., warrants and options) held by the Company’s stockholders or any third party debt holders or holders of
equity-linked securities (or in consideration of the assets of the Company in the case of a Change in Control structured as an asset sale, exclusive license or similar transaction), including, without limitation, amounts paid into escrow or subject

to Eligible Employees or employees who are not Eligible Employees (“Non-Eligible Employees”) chosen by the Plan Administrator, in its sole discretion, and the provision of any such benefits to an Eligible Employee or a
Non-Eligible Employee shall in no way obligate the Company to provide such benefits to any other Eligible Employee or to any other Non-Eligible Employee, even if similarly situated. If benefits under the Plan are provided to a Non-Eligible Employee,
references in the Plan to “Eligible Employee” (with the exception of Sections 4(a)(ii)(1), 4(a)(ii)(2), and 4(a)(ii)(3)) shall be deemed to refer to such Non-Eligible Employee. 
  

 8 

 SECTION 5. LIMITATIONS ON BENEFITS. 
 (a) Release. In order to be eligible to receive benefits under Section 4 of the Plan, an Eligible Employee must execute a general waiver and
release in substantially the form attached hereto as Exhibit A, Exhibit B, or Exhibit C, as appropriate, and such release must become effective in accordance with its terms. Unless a Change in Control has occurred, the Plan
Administrator, in its discretion, may modify the form of the required release to comply with applicable law and shall determine the form of the required release, which may be incorporated into a termination agreement or other agreement with the
Eligible Employee. 
 (b) Certain Reductions. The Plan Administrator, in its sole discretion, shall have the authority to reduce an
Eligible Employee’s benefits, in whole or in part, by any other benefits, pay in lieu of notice, or other similar benefits payable to the Eligible Employee by the Company that become payable in connection with a Change in Control or the
Eligible Employee’s termination of employment pursuant to (i) any applicable legal requirement, including, without limitation, the Worker Adjustment and Retraining Notification Act (the “WARN Act”), (ii) a
written employment or severance agreement with the Company, or (iii) any Company policy or practice providing for the Eligible Employee to remain on the payroll for a limited period of time after being given notice of the termination of the
Eligible Employee’s employment. The benefits provided in Section 4(a)(ii) under this Plan are intended to satisfy, in whole or in part, any and all statutory obligations that may arise out of an Eligible Employee’s termination of
employment, and the Plan Administrator shall so construe and implement the terms of the Plan. The Plan Administrator’s decision to apply such reductions to the severance benefits of one Eligible Employee and the amount of such reductions shall
in no way obligate the Plan Administrator to apply the same reductions in the same amounts to the severance benefits of any other Eligible Employee, even if similarly situated. In the Plan Administrator’s sole discretion, such reductions may be
applied on a retroactive basis, with severance benefits previously paid being re-characterized as payments pursuant to the Company’s statutory obligation. 
 (c) Parachute Payments. Except as otherwise provided in an agreement between an Eligible Employee and the Company, if any payment or benefit the Eligible Employee would receive in connection with a Change in
Control 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 the Eligible 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 the Eligible 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. 
  

 9 

 (d) Mitigation. Except as otherwise specifically provided herein, an Eligible Employee shall not
be required to mitigate damages or the amount of any payment provided under this Plan by seeking other employment or otherwise, nor shall the amount of any payment provided for under this Plan be reduced by any compensation earned by an Eligible
Employee as a result of employment by another employer or any retirement benefits received by such Eligible Employee after the date of the Eligible Employee’s termination of employment with the Company, except for health continuation coverage
provided pursuant to Section 4(a)(ii)(2). 
 (e) Non-Duplication of Benefits. Except as otherwise specifically provided for
herein, no Eligible Employee is eligible to receive benefits under this Plan more than one time. This Plan is designed to provide certain severance pay and change in control benefits to Eligible Employees pursuant to the terms and conditions set
forth in this Plan. The payments pursuant to this Plan are in addition to, and not in lieu of, any unpaid salary, bonuses or benefits to which an Eligible Employee may be entitled for the period ending with the Eligible Employee’s Covered
Termination. 
 SECTION 6. TIME OF PAYMENT AND FORM OF
BENEFITS. 
 (a) General Rules. The Plan Administrator reserves the right to determine whether cash severance
benefits under the Plan pursuant to Section 4(a)(ii), if any, shall be paid in a single lump sum or in installments, or in any other form, and to choose the timing of such payments. Benefits pursuant to Section 4(a)(i) shall be paid on the
same schedule and under the same terms and condition as apply to payments to secured debtholders and stockholders of the Company in the Change in Control. In no event shall payment of any benefit pursuant to Section 4(a)(ii) be made prior to
the Eligible Employee’s termination date or prior to the effective date of the release described in Section 5(a). 
 (b)
Application of Section 409A. In the event that (i) any benefit provided under Section 4(a)(i), (ii) cash severance benefit provided under Section 4(a)(ii)(1), (iii) the health continuation coverage provided under
Section 4(a)(ii)(2), or (iv) the outplacement benefit provided under Section 4(a)(ii)(3), fails to satisfy the distribution requirement of Section 409A(a)(2)(A) of the Code as a result of the application of
Section 409A(a)(2)(B)(i) of the Code, the payment of such benefit shall be accelerated to the minimum extent necessary so that the benefit is not subject to the provisions of Section 409A(a)(1) of the Code. (The payment schedule as revised
after the application of the preceding sentence shall be referred to as the “Revised Payment Schedule.”) However, in the event the payment of benefits pursuant to the Revised Payment Schedule would be subject to
Section 409A(a)(1) of the Code, the payment of such benefits shall not be paid pursuant to the original payment schedule or Revised Payment Schedule and instead the payment of such benefits shall be delayed to the minimum extent necessary so
that such benefits are not subject to the provisions of Section 409A(a)(1) of the Code. The Plan Administrator may attach conditions to or adjust the amounts paid pursuant to this Section 6(b) to preserve, as closely as possible, the
economic consequences that would have applied in the absence of this Section 6(b); provided, however, that no such condition shall result in the payments being subject to Section 409A(a)(1) of the Code. Payments pursuant to
Section 4(a)(i) shall be paid, if at all, no later than five years after the consummation of the Change in Control. No Eligible Employee shall have the right to receive payments pursuant to Section 4(a)(i) more than five years after the
consummation of the Change in Control. It is the intention that payments hereunder shall be paid pursuant to Treasury Regulation Section 1.409A-3(i)(5)(iv)(A). The Plan Administrator should interpret this Plan in compliance with
Section 409A of the Code. 
  

 10 

 (c) Tax Withholding. All such payments under the Plan will be subject to applicable
withholding for federal, state and local income and employment taxes. 
 (d) Indebtedness of Eligible Employees. If an Eligible
Employee is indebted to the Company on the effective date of his or her Covered Termination, the Plan Administrator reserves the right to offset any severance payments under the Plan by the amount of such indebtedness. 
 SECTION 7. REEMPLOYMENT. 
 In the event
of an Eligible Employee’s reemployment by the Company during the period of time in respect of which severance benefits pursuant to Sections 4(a)(ii)(1), 4(a)(ii)(2), and 4(a)(ii)(3) have been paid, the Plan Administrator, in its sole and
absolute discretion, may require such Eligible Employee to repay to the Company all or a portion of such severance benefits as a condition of reemployment. 
 SECTION 8. RIGHT TO INTERPRET PLAN; AMENDMENT AND TERMINATION. 
 (a) Exclusive Discretion. The Plan Administrator shall have the exclusive discretion and authority to establish rules, forms, and procedures for
the administration of the Plan, and to construe and interpret the Plan and to decide any and all questions of fact, interpretation, definition, computation or administration arising in connection with the operation of the Plan, including, but not
limited to, the eligibility to participate in the Plan and amount of benefits paid under the Plan. The rules, interpretations, computations and other actions of the Plan Administrator shall be binding and conclusive on all persons. 
 (b) Amendment or Termination. The Company reserves the right to amend or terminate this Plan or the benefits provided hereunder at any time;
provided, however, that no such amendment or termination shall occur following a Change in Control or a Covered Termination as to any Eligible Employee who would be adversely affected by such amendment or termination unless such Eligible
Employee consents in writing to such amendment or termination. Any action amending or terminating the Plan shall be in writing and executed by the Plan Administrator. 
 SECTION 9. NO IMPLIED EMPLOYMENT CONTRACT. 
 The Plan shall not be deemed (i) to give any employee or other person any right to be retained in the employ of the Company, or (ii) to interfere with the right of the Company to discharge any employee or other person at any time,
with or without cause, which right is hereby reserved. 
  

 11 

 SECTION 10. LEGAL CONSTRUCTION. 
 This Plan is intended to be governed by and shall be construed in accordance with ERISA and, to the extent not preempted by ERISA, the laws of the State
of California. 
 SECTION 11. CLAIMS, INQUIRIES AND APPEALS. 
 (a) Applications for Benefits and Inquiries. Any application for benefits, inquiries about the Plan or inquiries about present or future rights
under the Plan must be submitted to the Plan Administrator in writing by an applicant (or his or her authorized representative). The Plan Administrator is set forth in Section 13(d). 
 (b) Denial of Claims. In the event that any application for benefits is denied in whole or in part, the Plan Administrator must provide the
applicant with written or electronic notice of the denial of the application, and of the applicant’s right to review the denial. Any electronic notice will comply with the regulations of the U.S. Department of Labor. The notice of denial will
be set forth in a manner designed to be understood by the applicant and will include the following: 
 (i) the specific
reason or reasons for the denial; 
 (ii) references to the specific Plan provisions upon which the denial is based;

 (iii) a description of any additional information or material that the Plan Administrator needs to complete the

Plan’s review procedures and the time limits applicable to such procedures, including a statement of the applicant’s right to bring a civil action under Section 502(a) of ERISA following a denial on review of the claim, as described
in Section 11(d) below. 
 This notice of denial will be given to the applicant within ninety (90) days after the Plan
Administrator receives the application, unless special circumstances require an extension of time, in which case, the Plan Administrator has up to an additional ninety (90) days for processing the application. If an extension of time for
processing is required, written notice of the extension will be furnished to the applicant before the end of the initial ninety (90) day period. 
 This notice of extension will describe the special circumstances necessitating the additional time and the date by which the Plan Administrator is to render its decision on the application. 
 (c) Request for a Review. Any person (or that person’s authorized representative) for whom an application for benefits is denied, in
whole or in part, may appeal the denial by submitting a request for a review to the Plan Administrator within sixty (60) days after the application is denied. A request for a review shall be in writing and shall be addressed to: 
  

 12 

 Anesiva, Inc. 
 Attn: Chief Executive Officer 
 650 Gateway Boulevard 
 South San Francisco, CA 94080 
 A request for review must set forth all of the grounds
on which it is based, all facts in support of the request and any other matters that the applicant feels are pertinent. The applicant (or his or her representative) shall have the opportunity to submit (or the Plan Administrator may require the
applicant to submit) written comments, documents, records, and other information relating to his or her claim. The applicant (or his or her representative) shall be provided, upon request and free of charge, reasonable access to, and copies of, all
documents, records and other information relevant to his or her claim. The review shall take into account all comments, documents, records and other information submitted by the applicant (or his or her representative) relating to the claim, without
regard to whether such information was submitted or considered in the initial benefit determination. 
 (d) Decision on Review. The
Plan Administrator will act on each request for review within sixty (60) days after receipt of the request, unless special circumstances require an extension of time (not to exceed an additional sixty (60) days), for processing the request
for a review. If an extension for review is required, written notice of the extension will be furnished to the applicant within the initial sixty (60) day period. This notice of extension will describe the special circumstances necessitating
the additional time and the date by which the Plan Administrator is to render its decision on the review. The Plan Administrator will give prompt, written or electronic notice of its decision to the applicant. Any electronic notice will comply with
the regulations of the U.S. Department of Labor. In the event that the Plan Administrator confirms the denial of the application for benefits in whole or in part, the notice will set forth, in a manner calculated to be understood by the applicant,
the following: 
 (i) the specific reason or reasons for the denial; 
 (ii) references to the specific Plan provisions upon which the denial is based; 
 (iii) a statement that the applicant is entitled to receive, upon request and free of charge, reasonable access to, and copies of,
all documents, records and other information relevant to his or her claim; and 
 (iv) a statement of the
applicant’s right to bring a civil action under Section 502(a) of ERISA. 
 (e) Rules and Procedures. The Plan Administrator
will establish rules and procedures, consistent with the Plan and with ERISA, as necessary and appropriate in carrying out its responsibilities in reviewing benefit claims. The Plan Administrator may require an applicant who wishes to submit
additional information in connection with an appeal from the denial of benefits to do so at the applicant’s own expense. 
  

 13 

 (f) Exhaustion of Remedies. No legal action for benefits under the Plan may be brought until the
applicant (i) has submitted a written application for benefits in accordance with the procedures described by Section 11(a) above, (ii) has been notified by the Plan Administrator that the application is denied, (iii) has filed a
written request for a review of the application in accordance with the appeal procedure described in Section 11(c) above, and (iv) has been notified that the Plan Administrator has denied the appeal. Notwithstanding the foregoing, if the
Plan Administrator does not respond to an applicant’s claim or appeal within the relevant time limits specified in this Section 11, the applicant may bring legal action for benefits under the Plan pursuant to Section 502(a) of ERISA.

 SECTION 14. STATEMENT OF ERISA RIGHTS. 
 Participants in this Plan (which is a welfare benefit plan sponsored by Anesiva, Inc.) are entitled to certain rights and protections under ERISA. If you
are an Eligible Employee, you are considered a participant in the Plan for the purposes of this Section 14 and, under ERISA, you are entitled to: 
 (a) Receive Information About Your Plan and Benefits 
 (i) Examine, without
charge, at the Plan Administrator’s office and at other specified locations, such as worksites, all documents governing the Plan and a copy of the latest annual report (Form 5500 Series), if applicable, filed by the Plan with the U.S.
Department of Labor and available at the Public Disclosure Room of the Employee Benefits Security Administration; 
 (ii)
Obtain, upon written request to the Plan Administrator, copies of documents governing the operation of the Plan and copies of the latest annual report (Form 5500 Series), if applicable, and an updated (as necessary) Summary Plan Description. The
Administrator may make a reasonable charge for the copies; and 
 (iii) Receive a summary of the Plan’s annual
financial report, if applicable. The Plan Administrator is required by law to furnish each participant with a copy of this summary annual report. 
 (b) Prudent Actions By Plan Fiduciaries. In addition to creating rights for Plan participants, ERISA imposes duties upon the people who are responsible for the operation of the employee benefit plan. The people who operate the Plan,
called “fiduciaries” of the Plan, have a duty to do so prudently and in the interest of you and other Plan participants and beneficiaries. No one, including your employer, your union or any other person, may fire you or otherwise
discriminate against you in any way to prevent you from obtaining a Plan benefit or exercising your rights under ERISA. 
 (c) Enforce
Your Rights. 
 (i) If your claim for a Plan benefit is denied or ignored, in whole or in part, you have a right to
know why this was done, to obtain copies of documents relating to the decision without charge, and to appeal any denial, all within certain time schedules. 
 (ii) Under ERISA, there are steps you can take to enforce the above rights. For instance, if you request a copy of Plan documents or the latest annual report from the Plan, if applicable, and do not receive
them within 30 days, you may file suit in a Federal court. In such a case, the court may require the Plan Administrator to provide the materials and pay you up to $110 a day until you receive the materials, unless the materials were not sent because
of reasons beyond the control of the Plan Administrator. 
 (iii) If you have a claim for benefits which is denied or
ignored, in whole or in part, you may file suit in a state or Federal court. 
 (iv) If you are discriminated against
for asserting your rights, you may seek assistance from the U.S. Department of Labor, or you may file suit in a Federal court. The court will decide who should pay court costs and legal fees. If you are successful, the court may order the person you
have sued to pay these costs and fees. If you lose, the court may order you to pay these costs and fees, for example, if it finds your claim is frivolous. 
  

 15 

 (d) Assistance With Your Questions. If you have any questions about the Plan, you should contact
the Plan Administrator. If you have any questions about this statement or about your rights under ERISA, or if you need assistance in obtaining documents from the Plan Administrator, you should contact the nearest office of the Employee Benefits
Security Administration, U.S. Department of Labor, listed in your telephone directory or the Division of Technical Assistance and Inquiries, Employee Benefits Security Administration, U.S. Department of Labor, 200 Constitution Avenue N.W.,
Washington, D.C. 20210. You may also obtain certain publications about your rights and responsibilities under ERISA by calling the publications hotline of the Employee Benefits Security Administration. 
 SECTION 15. GENERAL PROVISIONS. 
 (a) Notices. Any notice, demand or request required or permitted to be given by either the Company or an Eligible Employee pursuant to the terms of this Plan shall be in writing and shall be deemed given when delivered personally or
deposited in the U.S. mail, First Class with postage prepaid, and addressed to the parties, in the case of the Company, at the address set forth in Section 11(a) and, in the case of an Eligible Employee, at the address as set forth in the
Company’s employment file maintained for the Eligible Employee as previously furnished by the Eligible Employee or such other address as a party may request by notifying the other in writing. 
 (b) Transfer and Assignment. The rights and obligations of an Eligible Employee under this Plan may not be transferred or assigned without the
prior written consent of the Company. This Plan shall be binding upon any surviving entity resulting from a Change in Control and upon any other person who is a successor by merger, acquisition, consolidation or otherwise to the business formerly
carried on by the Company without regard to whether or not such person or entity actively assumes the obligations hereunder. 
 (c)
Waiver. Any Party’s failure to enforce any provision or provisions of this Plan shall not in any way be construed as a waiver of any such provision or provisions, nor prevent any Party from thereafter enforcing each and every other
provision of this Plan. The rights granted the Parties herein are cumulative and shall not constitute a waiver of any Party’s right to assert all other legal remedies available to it under the circumstances. 
 (d) Severability. Should any provision of this Plan be declared or determined to be invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or impaired. 
 (e) Section Headings. Section headings in
this Plan are included for convenience of reference only and shall not be considered part of this Plan for any other purpose.

 I understand that this Release, together with the Plan, constitutes the complete, final and exclusive embodiment of the entire agreement between the Company and me with regard to the subject matter hereof. I am not
relying on any promise or representation by the Company that is not expressly stated therein. Certain capitalized terms used in this Release are defined in the Plan. 
 I hereby confirm my obligations under the Company’s proprietary information and inventions agreement. 
 Except as otherwise set forth in this Release, I hereby generally and completely release Anesiva, Inc. and its current and former 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 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

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, and the California Fair Employment and Housing
Act (as amended); provided, however, that nothing in this paragraph shall be construed in any way to release the Company from its obligation to indemnify me pursuant to agreement or applicable law. 
 I acknowledge that I have read and understand Section 1542 of the California Civil Code which reads as follows: “A general release does not
extend to claims which the creditor does not know or suspect to exist in his or her favor at the time of executing the release, which if known by him or her must have materially affected his or her settlement with the debtor.” I hereby
expressly waive and relinquish all rights and benefits under that section and any law of any jurisdiction of similar effect with respect to my release of any claims hereunder.

 I acknowledge that to become effective, I must sign and return this Release to the Company so that it is
received not later than fourteen (14) days following the date it is provided to me.
