party to provide such services during the Services Term, Anesiva and Sagent shall discuss in good faith possible ways to minimize any interference between the Services and such engagement. 
 5.3 No Other Licenses. Nothing in this Agreement shall be interpreted to grant either Party any rights under any patents, trademark, or other
intellectual property of the other Party that are not expressly granted herein, whether by implication, estoppel or otherwise. 
 5.4
Anesiva Trademarks. The ownership and use of the Anesiva Trademarks shall be governed by the following provisions: 
 (a) Anesiva
or an Affiliate of Anesiva shall retain the ownership of the entire right, title and interest in and to the Anesiva Trademarks. 
 (b)
Anesiva shall, at its cost and expense, file (to the extent necessary) in the Territory and endeavor in good faith to obtain the registration of the Anesiva Trademarks in the Territory, and, when registered, thereafter maintain the Anesiva
Trademarks in the Territory. Sagent agrees that in using Anesiva Trademarks in its activities under this Agreement it will not represent in any way that it has any right or title to the ownership of the Anesiva Trademarks or the registration
thereof, and the registration will remain in the ownership of Anesiva. Such Anesiva Trademarks will be used by Sagent on behalf of, and in the interest of, Anesiva, and Sagent will first obtain the written approval of Anesiva of the form and manner
in which the Anesiva Trademarks will be used upon, in connection with, or in relation to materials other than Promotion Materials as may be permitted by this Agreement. 
 (c) Sagent recognizes Anesiva’s title in and to the Anesiva Trademarks and to the registration thereof, and will not, at any time, do or authorize any act or thing that will in any way impair the rights of
Anesiva in and to the Anesiva Trademarks and the registration thereof. Wherever Anesiva’s trademarks or

tradenames are used (e.g., on any package, label or advertisement), the first or most prominent use shall always be accompanied by a legend acceptable
to Anesiva indicating that Product is a registered trademark of Anesiva and the Anesiva trademarks and tradenames are licensed to Sagent by Anesiva. In the event that Sagent, either directly or indirectly, challenges the title of Anesiva to any
Anesiva Trademark or the validity of such registration obtained by Anesiva for the same, and Sagent fails to withdraw such challenge within [*] of receipt of Anesiva’s written request therefor, Anesiva shall have the right to terminate this
Agreement. 
 (d) Sagent shall, upon Anesiva’s request, and at Anesiva’s expense, reasonably assist Anesiva in any action
reasonably necessary or desirable to protect the Anesiva Trademarks used or proposed to be used hereunder. Sagent shall as soon as practicable notify Anesiva of any apparent infringement by a Third Party of any of the Anesiva Trademarks. 

(e) After discussion and upon notice and demand from Anesiva, Sagent shall immediately discontinue the use of any of the Anesiva Trademarks upon
notice from a Third Party that such use is or is alleged to be an infringement of such Third Party’s trademark rights, unless Sagent determines that it does not wish to discontinue use of any of the Anesiva Trademarks, in which case all
liability of Anesiva, Sagent and their respective Affiliates arising out of Sagent’s use of any such Anesiva Trademark after such notice shall be borne by Sagent. In the event of any such Third Party notice, request by Anesiva to discontinue
the use of an Anesiva Trademark and subsequent discontinuance by Sagent, Anesiva shall select a new Anesiva Trademark to be used with Product and shall promptly notify Sagent in writing of such selection.

communication shall be held in confidence by Sagent pursuant and subject to the terms of Article 11. Should either Party learn of any hazard that is severe, serious or unexpected, concerning the Product, such hazard data shall be communicated
to the other Party immediately in writing or confirmed in writing if such immediate communication is non-written. Anesiva shall be responsible for complying with all applicable laws regarding the reporting of such hazards to governmental
authorities. The aforementioned information shall be addressed as follows:

Article 7, for whatever reason, then, in any such case, all of Sagent’s rights hereunder regarding Product and the use of the Anesiva Trademarks and the Promotional Materials shall automatically terminate and automatically revert to
Anesiva, effective as of such time, and Sagent shall have no further rights thereto. Upon termination or expiration hereof, Sagent shall immediately cease performing the Services and promptly return to Anesiva all Promotional Materials and samples

expiration or termination of this Agreement shall not relieve the Parties of any liability which accrued hereunder prior to the effective date of such expiration or termination nor preclude either Party from pursuing all rights and remedies it may
have hereunder or at law or in equity with respect to any breach of this Agreement, nor prejudice either Party’s right to obtain performance of any obligation. Notwithstanding the foregoing, the use by either Party hereto of a termination right
provided for under this Agreement shall not give rise to the payment of damages or any other form of compensation or relief to the other Party with respect thereto.

Party, to the extent arising out of, relating to, or resulting from (a) the breach by Anesiva of any of its covenants, representations, or warranties contained within this Agreement; (b) the gross negligence or willful misconduct of
Anesiva, its Affiliates, or their respective directors, officers, employees and, agents; or (c) the manufacture, use or sale of Product, in each case except to the extent such claim, lawsuit or other action results from the gross negligence or
willful misconduct of a Sagent Indemnitee or from Sagent’s breach of this Agreement. 
 10.2 Indemnification by Sagent. Subject
to Section 10.3, Sagent shall indemnify, defend and hold Anesiva, its Affiliates, and their respective directors, officers, employees, and agents (collectively, “Anesiva Indemnitees”) harmless from and against any Liabilities

(b) shall not use such Confidential Information for any purpose except as permitted by this Agreement; and (c) shall not disclose such Confidential Information to anyone other than those of its Affiliates, sublicensees, prospective

connection with such Party’s activities as contemplated in this Agreement. Each Party shall ensure that such Party’s Affiliates, sublicensees, prospective sublicensees, employees, consultants, agents and subcontractors comply with these
obligations. Each Party shall notify the other promptly on discovery of any unauthorized use or disclosure of the other’s Confidential Information, including without limitation, the other’s trade secrets or proprietary information.

 11.2 Exceptions. The obligations of confidentiality, non-disclosure, and non-use set forth in Section 11.1 shall not apply to
the extent the receiving Party (the “Recipient”) can demonstrate that the disclosed information (a) was in the public domain at the time of disclosure to the Recipient by the other Party, or thereafter entered the public

written records) prior to the date of disclosure to the Recipient by the other Party; or (c) was received by the Recipient or its Affiliates on an unrestricted basis from a Third Party rightfully in possession of such information and not under
a duty of confidentiality to the other Party. Notwithstanding any other provision of this Agreement, Recipient’s disclosure of Confidential Information shall not be prohibited if such disclosure: (i) is in response to a valid order of a
court or other governmental body of the U.S., provided that Recipient provides the other Party with prior written notice of such disclosure in order to permit the other Party to seek a protective order or other confidential treatment of such
Confidential Information; or (ii) is otherwise required by applicable law or regulation or by the rules of a nationally recognized securities exchange. 
 11.3 Publicity. The Parties agree that the public announcement of the execution of this Agreement shall be substantially in the form of the press release attached as Exhibit C. Any other publication,

by the rules of a nationally recognized securities exchange as advised by the disclosing Party’s counsel may be made without the prior consent of the other Party, although the other Party shall be given prompt notice of any such legally

	12.	GENERAL PROVISIONS 

 12.1 Performance by Affiliates. The Parties recognize that each Party may perform some or all of its obligations under this Agreement through Affiliates; provided, however, that each Party shall remain
responsible for the performance by its Affiliates and shall cause its Affiliates to comply with the provisions of this Agreement in connection with such performance. Each Party hereby expressly waives any requirement that the other Party exhaust any
right, power or remedy, or proceed against an Affiliate, for any obligation or performance hereunder prior to proceeding directly against such Party. 
 12.2 Entire Agreement; Amendment. This Agreement by and between the Parties hereto, is both a final expression of the Parties’ agreement and a complete and exclusive statement with respect to all of its
terms. The Exhibits referred to in this Agreement are incorporated herein and made a part of this Agreement by this reference. This Agreement supersedes all prior and contemporaneous agreements and communications, whether oral, written or otherwise,
concerning any and all matters contained herein. No trade customs, courses of dealing or courses of performance by the Parties shall be relevant to modify, supplement or explain any term(s) used in this Agreement. This Agreement may only be amended,
modified or supplemented in a writing expressly stated for such purpose and signed by the Parties to this Agreement.

Parties. Neither Party is a legal representative of the other Party, and neither Party can assume or create any obligation, representation, warranty or guarantee, express or implied, on behalf of the other Party for any purpose whatsoever.

 12.4 Non-Waiver. The failure of a Party to insist upon strict performance of any provision of this Agreement or to exercise any
right arising out of this Agreement shall neither impair that provision or right nor constitute a waiver of that provision or right, in whole or in part, in that instance or in any other instance. 
 12.5 Assignment. No Party may assign or delegate any or all of its rights or obligations under this Agreement without the prior written consent of
every other Party to this Agreement except to an Affiliate. If a Party assigns this Agreement to an Affiliate, such Party will also promptly inform the other Party and guarantee the performance by its Affiliate of all of such Party’s
obligations under the Agreement. Notwithstanding the foregoing, Anesiva may, with notice, but without Sagent’s consent and at Anesiva’s sole discretion, assign any or all of

its rights and obligations under this Agreement to a Third Party in connection with the sale, transfer or other disposition of the part of Anesiva’s
business to which this Agreement relates. Any assignment or delegation of rights or obligations under this Agreement that is not in compliance with this Section 12.5 shall be void and without effect. This Agreement is binding upon and inures to
the benefit of the Parties to it, and to their permitted successors and assigns. 
 12.6 No Third Party Beneficiaries. This Agreement
is neither expressly nor impliedly made for the benefit of any party other than those executing it. 
 12.7 Severability. If, for any
reason, any part of this Agreement is adjudicated invalid, unenforceable or illegal by a court of competent jurisdiction, such adjudication shall not affect or impair, in whole or in part, the validity, enforceability or legality of any remaining
portions of this Agreement. All remaining portions shall remain in full force and effect as if the original Agreement had been executed without the invalidated, unenforceable or illegal part. 
 12.8 Notices. Any notice to be given under this Agreement must be in writing and delivered either in person, by any method of mail (postage
prepaid) requiring return receipt, or by overnight courier or facsimile confirmed thereafter by any of the foregoing, to the Party to be notified at its address(es) given below, or at any address such Party has previously designated by prior written
notice to the other. Notice shall be deemed sufficiently given for all purposes upon the earlier of: (a) the date of actual receipt; (b) if mailed, three calendar days after the date of postmark; or (c) if delivered by overnight

strike or labor disturbance, or any other event similar to those enumerated above. Such excuse from liability shall be effective only to the extent and duration of the event(s) causing the failure or delay in performance and provided that the Party
has not caused such event(s) to occur. Notice of a Party’s failure or delay in performance due to force majeure must be given to the other Party within [*] after its occurrence. Notwithstanding the foregoing, should the event(s) of force
majeure suffered by a Party extend beyond a [*], the other Party may then terminate this Agreement by written notice to the non-performing Party, with the consequences of such termination as set forth in Sections 7.4 and 7.5. 
 12.10 LIMITATION OF LIABILITY. NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR ANY SPECIAL, CONSEQUENTIAL, INCIDENTAL, PUNITIVE, OR INDIRECT
DAMAGES ARISING FROM OR RELATING TO ANY BREACH OF THIS AGREEMENT, REGARDLESS OF ANY NOTICE OF THE POSSIBILITY OF SUCH DAMAGES. NOTWITHSTANDING THE FOREGOING, NOTHING IN THIS PARAGRAPH IS INTENDED TO LIMIT OR RESTRICT THE INDEMNIFICATION RIGHTS OR

thereof (a “Dispute”) through good faith negotiations between the Project Leads in the spirit of mutual cooperation. If the Project Leads are unable to resolve such Dispute within [*], the Parties shall submit such Dispute to the
Parties’ respective Senior Executives for good faith discussion and attempted resolution. If the Senior Executives are unable to resolve such Dispute within [*], such Dispute shall be settled by final and binding arbitration in San Francisco,
California pursuant to then current rules for arbitration of commercial disputes promulgated by the American Arbitration Association. Judgment upon the award rendered by the arbitrator may be entered in any court having jurisdiction thereof. In no
event shall the arbitrator have any right or power to award punitive or exemplary damages. All negotiations and discussions pursuant to this Section 12.11 shall be confidential, and the Parties agree that all information concerning or disclosed
as part of such negotiations and discussions are and such shall be treated as compromise and settlement negotiations for purposes of applicable rules of evidence.

 ANESIVA SIGNS CO-PROMOTION AND DISTRIBUTION AGREEMENT WITH SAGENT PHARMACEUTICALS

 FOR ZINGOTM IN U.S. HOSPITALS 
 Sagent to Accelerate Anesiva’s Penetration of the Hospital Market with Zingo 
 SOUTH SAN FRANCISCO, CA,
and SCHAUMBURG, IL, October 12, 2007 — Anesiva, Inc. (Nasdaq: ANSV) and Sagent Pharmaceuticals, Inc., today announced an agreement in which Sagent will co-promote for three years Anesiva’s ZingoTM (lidocaine hydrochloride
monohydrate) powder intradermal injection product and will manage U.S. distribution. Zingo, a needle-free product that provides fast-acting topical, local analgesia, has been recently approved by the U.S. Food and Drug Administration (FDA) to reduce
the pain associated with venous access procedures, such as IV insertions or blood draws, in children three to 18 years of age. 
 Under the agreement, Sagent
will join with Anesiva to co-promote Zingo within hospitals as well as facilitating contract negotiations with hospitals and group purchasing organizations. Sagent’s team will focus their selling efforts toward hospital pharmacists, with
Anesiva promoting primarily to physicians and nurses. In addition, Sagent will manage Zingo warehousing and distribution services. The terms of the agreement provide for Sagent to earn a royalty based on Anesiva’s net sales of Zingo and for
Anesiva to reimburse Sagent for certain direct expenses. Anesiva may designate additional marketing partners to address non-hospital affiliated markets.

 “We are very excited to work with their extremely seasoned sales and national accounts team to support Zingo’s
penetration of the hospital market,” said John P. McLaughlin, chief executive officer of Anesiva. “Together with Anesiva’s experienced marketing organization and planned sales force of 15 representatives, we will have complementary
roles and provide synergistic selling efforts to launch Zingo successfully in U.S. hospitals. Anesiva will also leverage Sagent’s established infrastructure for warehousing and distribution services.” 
 “We are excited about the opportunity to collaborate with an organization of Anesiva’s quality in introducing Zingo to hospital markets and will fully align
our extensive hospital-focused sales and distribution resources to support Zingo,” stated Jeffrey Yordon, chairman, founder and chief executive officer of Sagent Pharmaceuticals. “The Anesiva co-promote marks an important advance in
Sagent’s rapid evolution and Zingo fits nicely with Sagent’s mission of delivering customer-focused products to patients.” 
 About Zingo

 Zingo is a ready-to-use, single-use, needle-free system that delivers 0.5 mg sterile lidocaine powder into the skin and provides topical, local
analgesia in one to three minutes after administration. This rapid onset, which may be especially useful in pediatric populations and busy emergency room settings, means the product can be incorporated into a medical procedure allowing uninterrupted
care, an important advantage over current options. Venous access procedures, like IV insertions and blood draws, are among the most common interventions performed at a hospital, with more than 18 million pediatric venous access procedures and
400 million total procedures per year in U.S hospitals. In addition to the hospital setting, Zingo may be used in physicians’ offices and clinical laboratories. In clinical trials, Zingo was well tolerated. Common side effects were
redness, red dots and swelling of the skin at the site of administration. 
 About Anesiva and its Diverse Pipeline of Pain Products 
 Anesiva, Inc. is a late-stage biopharmaceutical company that seeks to be the leader in the development and commercialization of novel therapeutic treatments for pain. The
company has one FDA-approved product, ZingoTM, for the reduction of pain associated with peripheral venous access procedures in children three to 18 years of age. The second product in Anesiva’s pipeline, AdleaTM (formerly 4975), has
been shown to reduce pain after only a single administration for weeks to months in multiple settings in numerous mid-stage clinical trials for site-specific, moderate-to-severe pain. Anesiva is based in South San Francisco, CA. For more information
about Anesiva’s leadership in the development of products for pain management, and an overview of the clinical challenges being addressed by its product candidates, go to http://www.anesiva.com.
