Net Sales. Any free-of-charge disposal or use of a Product for development, regulatory or marketing purposes, such as clinical trials, compassionate use or indigent patient programs, shall not be deemed a sale or disposition for purposes of calculating Net Sales.

3. LICENSES AND OTHER RIGHTS

3.1 License and Sublicense Grant. Subject to the terms and conditions of this Agreement, Vical hereby grants to Astellas an exclusive (even as to Vical and its Affiliates, but subject to Vical’s performance of such development, regulatory and manufacturing activities as agreed in writing by the parties), royalty-bearing license and sublicense, with the right to sublicense in accordance with Section 3.2, under the Vical Technology, to research, develop, register, make, have made, use, promote, distribute, sell, offer for sale, have sold, import and export Products in the Field in the Territory.

3.2 Sublicensing. Astellas shall have the right to grant sublicenses under the license granted in Section 3.1 to one or more Third Parties or Affiliates subject to the provisions of this Section 3.2. Each agreement under which Astellas grants a sublicense under the license granted in Section 3.1 (each, a “Sublicense Agreement”) shall (a) be in writing and (b) be consistent with, and subject to the terms and conditions of, this Agreement (including the terms relating to sublicenses of Vical Technology licensed or conveyed to Vical under the CytRx Agreement, as applicable). Astellas shall be responsible for compliance of any Sublicensee with this Agreement. Any breach of this Agreement by the acts or omissions of a Sublicensee shall be a breach of this Agreement by Astellas. Astellas shall provide Vical with a full and complete copy of each Sublicense Agreement with a Third Party (and if required by the CytRx Agreement, each Sublicense Agreement with an Affiliate) within […***…] ([…***…]) days after execution thereof; provided, that Astellas may redact any confidential information contained therein that is not necessary to disclose to ensure compliance with this Agreement.

3.3 In-License Agreements. Astellas acknowledges that the Vical Technology licensed or otherwise conveyed to Vical under the CytRx Agreement is subject to the applicable terms and conditions of the CytRx Agreement. In the event that CytRx notifies Vical of a default or breach under the CytRx Agreement related to any failure by Astellas or any Sublicensee to perform any obligation or covenant under this Agreement, the parties will discuss how to resolve the matter and, if the parties agree to a proposed resolution of the matter, they will cooperate in responding to CytRx. If Astellas does not resolve such matter as agreed by the parties, or if the parties do not agree to a resolution of the matter, then Vical shall have the right, but not the obligation, to take such actions as reasonably necessary or appropriate to cure such default or breach and shall keep Astellas reasonably informed regarding such actions, and Astellas shall promptly reimburse Vical for all reasonable costs and expenses actually incurred by Vical solely as a result of such default or breach by Astellas or any Sublicensee.

***Confidential Treatment Requested

13

terms, conditions or obligations of this Agreement. In addition, in the event the rights to the Vical Technology licensed to Vical under the CytRx Agreement cease to be licensed to Vical under the CytRx Agreement and Astellas obtains a license with respect to such Vical Technology directly from CytRx, then Astellas may deduct from the applicable payments owed to Vical hereunder the amount actually paid by Astellas to CytRx for such license with respect to such Vical Technology up to the amount that Vical would have been obligated to pay to CytRx under the CytRx Agreement with respect to such payment.

3.4 Disclosure of Vical Know-How. Upon Astellas’ request, Vical shall make available to Astellas Vical Know-How in Vical’s possession that has not previously been provided to Astellas, including any raw data and/or original data relating to Compounds and Products in the Field; provided that any Vical Know-How relating to the manufacture of Compounds and Products in the Field shall be made available through a technology transfer arrangement as provided in the Services Agreement. Vical shall not destroy, discard or otherwise dispose of or shall have not destroyed, discarded or otherwise disposed of any Vical Know-How without prior written approval of Astellas, which approval shall not be unreasonably withheld.

(b) Reserved Products. The provisions of this Section 3.5(b) shall apply with respect to any Product other than an Excluded Product (a “Reserved Product”) outside the Field in the Territory. Vical retains all rights, directly or indirectly through any Affiliate or Third Party, to research, develop, market, promote, distribute, offer for sale or sell, or grant any license or sublicense under the Vical Technology to research, develop, market, promote, distribute, offer for sale or sell, any Reserved Product outside the Field in the Territory, subject to this Section 3.5(b) (any such Reserved Product with respect to which Vical has retained rights, a “Vical Reserved Product”). Astellas may notify Vical in writing that it proposes to designate any Reserved Product as an “Astellas Reserved Product,” specifying whether such Reserved Product would contain a Compound alone, a Compound formulated with an adjuvant (identifying the adjuvant) or a Compound administered through a delivery system (identifying the delivery system). Astellas may provide such written request at any time after it or its

14

Sublicensee has initiated good laboratory practices preclinical studies of such Reserved Product. The Reserved Product specified in such written notice from Astellas shall be deemed an Astellas Reserved Product unless Vical provides written notice to Astellas within thirty (30) days after Vical’s receipt of such written notice from Astellas that Vical has granted a license or similar rights with respect to such Product to a Third Party or has initiated good laboratory practices preclinical studies of such Reserved Product, in which case such Reserved Product shall not be an Astellas Reserved Product and shall remain a Vical Reserved Product. During the Term for so long as Astellas uses Commercially Reasonable Efforts to develop, manufacture and commercialize an Astellas Reserved Product, Vical shall not, directly or indirectly through any Affiliate or Third Party, market, promote, distribute, offer for sale or sell, or grant any license or sublicense under the Vical Technology to market, promote, distribute, offer for sale or sell, such Astellas Reserved Product outside the Field in the Territory.

(c) By Astellas. During the Term, Astellas shall not, directly or indirectly through any Affiliate or Third Party, market, promote, distribute, offer for sale or sell, or grant any license or sublicense to market, promote, distribute, offer for sale or sell, any DNA vaccine product for use in the Field in the Territory, other than Products in the Field in the Territory (a “Competitive Product”). Further, Astellas agrees not to practice any Vical Technology except to develop, register, make, have made, use, promote, distribute, sell, offer for sale, have sold, import and export Products in the Field in the Territory during the Term in accordance with the terms of this Agreement and any other written agreement between the parties.

If Astellas or its Affiliate elects to divest itself of such Competitive Product, such divesture shall occur by an outright sale to a Third Party of all of Astellas’ and its Affiliate’s rights to such Competitive Product. For clarity, the commercialization of such Competitive Product during the Restricted Period shall not constitute a violation of Section 3.5(c).

3.6 Retained Rights; No Implied Licenses. Except for the rights and licenses expressly granted in this Agreement, Vical retains all rights under the Vical Technology, and no rights shall be deemed granted by Vical to Astellas by implication, estoppel or otherwise.

Neither party shall have the right to settle any patent infringement litigation with respect to any Vical Patent under this Section 7.4 in a manner that diminishes the rights or interests of the other party without the consent of such other party (which shall not be unreasonably withheld). Except as otherwise agreed to by the parties as part of a cost-sharing arrangement, any recovery or damages realized as a result of such action or proceeding shall be used first to reimburse the parties’ documented out-of-pocket legal expenses relating to the

***Confidential Treatment Requested

action or proceeding, and any remaining damages relating to the Products (including lost sales or lost profits with respect to Products) shall be retained by the party that brought and controlled the action and, if Astellas brought and controlled such action, shall be deemed Net Sales subject to the royalty provisions of Section 5.3.

7.5 Third Party Infringement Claims. Each party shall promptly notify the other party in writing of any allegation by a Third Party that the activity of either party with respect to the development, manufacture or commercialization of any Product in the Field in the Territory infringes or may infringe the intellectual property rights of such Third Party. Vical shall have the sole right to control any defense of any such claim involving alleged infringement of Third Party rights by Vical’s activities, at Vical’s sole cost and expense and by counsel of its own choice, and Astellas shall have the right, at its own expense, to be represented in any such action by counsel of its own choice. Astellas shall have the sole right to control any defense of any such claim involving alleged infringement of Third Party rights by Astellas’ activities, at Astellas’ sole cost and expense and by counsel of its own choice, and Vical shall have the right, at its own expense, to be represented in any such action by counsel of its own choice. Neither party shall enter into any settlement or compromise of any action under this Section 7.5 which would in any manner diminish the rights or interests of the other party without the consent of such other party (which shall not be unreasonably withheld).

7.6 Orange Book Listing. Astellas shall have the sole right to make any filing with respect to any Vical Primary Patents in connection with the Patent listing source in any country in the Territory that is equivalent to the Orange Book, if any. Upon request of Astellas, with respect to countries in the Territory, Vical shall cooperate with Astellas to file appropriate information with the applicable Regulatory Authority listing any Vical Primary Patents.

7.7 Patent Marking. Astellas shall mark all Products made, used or sold in the Territory, or their containers, if required under applicable laws, rules and regulations relating to patent marking.

7.8 Registration of License. Astellas may, at its sole discretion and at its own expense, register the license granted under this Agreement with the patent office or any other competent authorities in any country of the Territory in accordance with the relevant law in such country, and Vical shall, promptly upon Astellas’ request, provide Astellas with assistance necessary for such registration, including without limitation applying for such registration for Astellas and signing all necessary documents.

7.9 Trademarks. Astellas shall be responsible for selection, registration and maintenance of the trademark(s) for Products in the Field in the Territory, at its own cost, and all such trademark(s) shall be filed and exclusively owned by Astellas. At Astellas’ election, Vical shall grant to Astellas during the Term a royalty-free exclusive license with the right to sublicense under Vical’s interest in Vical’s common law trademark TransVax™ for use solely in connection with the sale and offer for sale of Products in the Field in the Territory. Such license shall become perpetual in the event Astellas obtains a perpetual and fully paid-up license and sublicense under the Vical Technology pursuant to Section 10.1. For clarity, Vical is and shall remain the owner of all right, title and interest in and to Vical’s common law trademark

25

TransVax™ and the goodwill now and hereafter associated therewith shall at all times inure to the benefit of Vical.

8.4 Limitation of Liability.

9. CONFIDENTIALITY

9.1 Confidential Information. Except to the extent expressly authorized by this Agreement or otherwise agreed in writing by the parties, the parties agree that, during the Term

27

and until the […***…] ([…***…]) anniversary of the date of expiration or termination of the later to expire or terminate of this Agreement or the U.S. Agreement, each party (in such capacity, the “receiving party”) shall keep confidential and shall not publish or otherwise disclose and shall not use for any purpose other than as expressly provided for in this Agreement or the Confidentiality Agreement any Confidential Information of the other party (in such capacity, the “disclosing party”). The receiving party may use Confidential Information of the other party only to the extent required to accomplish the purposes of this Agreement. The receiving party will use at least the same standard of care as it uses to protect proprietary or confidential information of its own (but not less than reasonable care) to ensure that its employees, agents, consultants and other representatives do not disclose or make any unauthorized use of the Confidential Information of the disclosing party. The receiving party will promptly notify the disclosing party upon discovery of any unauthorized use or disclosure of the Confidential Information of the disclosing party. Without limiting the foregoing, the parties acknowledge that Vical Know-How includes valuable trade secrets and that it is in the interests of both parties to protect the confidentiality of the Vical Know-How; provided, that nothing will limit or prevent Vical from using or disclosing the Vical Know-How in connection with its discussions and activities outside the scope of the exclusive license granted to Astellas hereunder with respect to Compounds and Products in the Field in the Territory.

9.2 Exceptions. Confidential Information shall not include any information which the receiving party can demonstrate by competent evidence: (a) is now, or hereafter becomes, through no act or failure to act on the part of the receiving party, generally known or available; (b) is known by the receiving party at the time of receiving such information, as evidenced by its records; (c) is hereafter furnished to the receiving party by a Third Party, as a matter of right and without restriction on disclosure; or (d) is independently discovered or developed by the receiving party without the use of Confidential Information of the disclosing party.

9.3 Authorized Disclosure. The receiving party may disclose Confidential Information of the disclosing party as expressly permitted by this Agreement or if and to the extent such disclosure is reasonably necessary in the following instances:

(a) prosecuting or defending litigation as permitted by this Agreement;

(b) complying with applicable court orders or governmental regulations;

(c) in the case of Astellas, conducting development manufacturing and/or commercialization activities in accordance with the license granted in Section 3.1, including making regulatory filings with respect to Products;

(d) in the case of Vical, as reasonably necessary to fulfill its obligations under the CytRx Agreement; and

(e) disclosure to Affiliates, sublicensees, subcontractors, employees, consultants, agents or other Third Parties who need to know such information for the development, manufacture and commercialization of Products in accordance with this Agreement or in connection with due diligence or similar investigations by such Third Parties, and disclosure to potential Third Party investors in confidential financing documents, provided,

***Confidential Treatment Requested

28

in each case, that any such Affiliate, sublicensee, subcontractor, employee, consultant, agent or Third Party agrees to be bound by similar terms of confidentiality and non-use at least equivalent in scope to those set forth in this Article 9.

Notwithstanding the foregoing, in the event the receiving party is required to make a disclosure of the disclosing party’s Confidential Information pursuant to Section 9.3(a) or (b), it will, except where impracticable, give reasonable advance notice to the disclosing party of such disclosure and use efforts to secure confidential treatment of such information at least as diligent as the receiving party would use to protect its own confidential information, but in no event less than reasonable efforts. In any event, the receiving party agrees to take all reasonable action to avoid disclosure of Confidential Information of the disclosing party.

9.4 Confidentiality of this Agreement and its Terms. Except as otherwise provided in this Article 9, each party agrees not to disclose to any Third Party the existence of this Agreement or the terms of this Agreement without the prior written consent of the other party hereto, except that each party may disclose the terms of this Agreement that are not otherwise made public as contemplated by Section 9.5 as permitted under Section 9.3.

9.5 Public Announcements.

(a) Press Releases. As soon as practicable following the date hereof, the parties shall each issue a mutually agreed press release announcing the existence of this Agreement. Except as required by applicable laws and regulations (including disclosure requirements of the U.S. Securities and Exchange Commission (“SEC”) or any stock exchange on which securities issued by a party or its Affiliates are traded), neither party shall make any other public announcement concerning this Agreement or the subject matter hereof without the prior written consent of the other, which shall not be unreasonably withheld or delayed; provided that each party may make any public statement, including statements in response to questions by the press, analysts, investors or those attending industry conferences or financial analyst calls, or issue press releases, so long as any such public statement or press release is not inconsistent with prior public disclosures or public statements approved by the other party pursuant to this Section 9.5 and which do not reveal non-public information about the other party. For avoidance of doubt, Vical shall have the right, without the prior written consent of Astellas, to announce events such as achievement of milestones under this Agreement, and other events deemed material by its General Counsel; provided, however, that Vical shall consult with Astellas with regard thereto and provide reasonable opportunity for Astellas to review such announcement in advance. In the event of a required public announcement, to the extent practicable under the circumstances, the party making such announcement shall provide the other party with a copy of the proposed text of such announcement sufficiently in advance of the scheduled release to afford such other party a reasonable opportunity to review and comment upon the proposed text.

(b) Filing of Agreement. The parties will coordinate in advance with each other in connection with the filing of this Agreement (including redaction of certain provisions of this Agreement) with the SEC or any stock exchange or governmental agency on which securities issued by a party or its Affiliate are traded, and each party will use reasonable efforts to seek confidential treatment for the terms proposed to be redacted; provided that each party will ultimately retain control over what information to disclose to the SEC or any stock exchange

29

or other governmental agency, as the case may be, and provided further that the parties will use their reasonable efforts to file redacted versions with any governing bodies which are consistent with redacted versions previously filed with any other governing bodies. Other than such obligation, neither party (or its Affiliates) will be obligated to consult with or obtain approval from the other party with respect to any filings to the SEC or any stock exchange or other governmental agency.

(c) Publications.

(i) Except as otherwise set forth in Section 9.5(c)(ii) below, at least […***…] ([…***…]) days prior to publishing, publicly presenting, and/or submitting for written or oral publication a manuscript, abstract or the like that includes Information relating to any Product in the Field that has not been previously published, each party shall provide to the other party a draft copy thereof for its review (unless such party is required by law to publish such Information sooner, in which case such party shall provide such draft copy to the other party as much in advance of such publication as possible). The publishing party shall consider in good faith any comments provided by the other party during such […***…] ([…***…]) day period. In addition, the publishing party shall, at the other party’s reasonable request, remove therefrom any Confidential Information of such other party, except each party shall have the right to publicly disclose any information, including Confidential Information, pertaining to safety or efficacy of the Product that such party believes in good faith it is obligated by applicable law or appropriate to conform to applicable regulatory requirements to disclose; provided that it shall delay publication for a period not to exceed […***…] ([…***…]) days in order to allow the other party to file for patent protection as permitted by this Agreement in relation to its Confidential Information. The contribution of each party shall be noted in all publications or presentations by acknowledgment or co-authorship, as appropriate.

(ii) In the event Astellas desires to publish, publicly present, and/or submit for written or oral publication a manuscript, abstract or the like that includes Information relating to any Product in the Field but that does not include any Confidential Information of Vical, Astellas shall provide to Vical a draft copy thereof for its review prior to the date of such publication, presentation or submission, and Astellas shall consider in good faith any comments provided by Vical with respect thereto.

(iii) Astellas shall, within a reasonable amount of time after the Effective Date and from time to time thereafter, provide to Vical a copy of its plan for publication regarding Compounds and Products in the Field, including all material updates and changes thereto.

9.6 Equitable Relief. Given the nature of the Confidential Information and the competitive damage that would result to the disclosing party upon unauthorized disclosure, use or transfer of its Confidential Information to any Third Party, the parties agree that monetary damages may not be a sufficient remedy for any breach of this Article 9. In addition to all other remedies, the disclosing party shall be entitled to seek specific performance and injunctive and other equitable relief as a remedy for any breach or threatened breach of this Article 9.

34

obligated to pay the fees and expenses of any separate counsel retained by the indemnified party with respect to such Losses.

11.4 Insurance. Each party shall, at its own expense, procure and maintain during the Term and for a period of three (3) years thereafter, insurance policy/policies, including product liability insurance, adequate to cover its obligations hereunder and which are consistent with normal business practices of prudent companies similarly situated.

Notwithstanding the foregoing, Section 12.1 shall no longer apply (i) during a period commencing with Vical’s announcement in a filing with the Securities and Exchange Commission or a press release that (a) it is seeking purchaser for itself or (b) is otherwise exploring strategic options in this regard, and ending with Vical’s announcement in a filing with the Securities and Exchange Commission or a press release that is terminating such search or exploration; (ii) during the period beginning with the commencement by a Third Party of a publicly-announced tender or exchange offer for more than […***…] percent ([…***…]%) of voting power of the outstanding voting securities of Vical, and ending with the termination by such Third Party of such tender or exchange offer; or (iii) if Vical announces in a filing with the Securities and Exchange Commission or a press release a transaction, or an intention to effect any transaction, which would result in (a) the sale by Vical or one or more Affiliate(s) of assets representing […***…] percent ([…***…]%) or more of the consolidated assets of Vical; or (b) the common shareholders of Vical immediately prior to such transaction owning less than […***…] percent ([…***…]%) of the outstanding common stock of the acquiring entity or, in case of a merger transaction, the surviving corporation (or, if the surviving corporation is an Affiliate of a parent company, the parent company); provide that, in the case of clause (ii) Astellas has not directly or indirectly taken any action prohibited under this Section 12.1.

The expiration of the Standstill Period will not terminate or otherwise affect any of the other provisions of this Agreement.

12.2 Governing Law. This Agreement shall be governed by, and construed and enforced in accordance with, the laws of the State of New York, excluding its conflicts of laws principles with the exception of sections 5-1401 and 5-1402 of New York General Obligations Law.

12.3 Dispute Resolution.

(a) Objective. The parties recognize that disputes as to matters arising under or relating to this Agreement or either party’s rights and/or obligations hereunder may arise from time to time. It is the objective of the parties to establish procedures to facilitate the resolution of such disputes in an expedient manner by mutual cooperation and without resort to litigation. To

***Confidential Treatment Requested

36

accomplish this objective, the parties agree to follow the procedures set forth in this Section 12.3 to resolve any such dispute if and when it arises.

(b) Resolution by Executives. Except as otherwise provided in Section 2.1, if an unresolved dispute as to matters arising under or relating to this Agreement or either party’s rights and/or obligations hereunder arises, either party may refer such dispute to the Executives, who shall meet in person or by telephone within ten (10) days after such referral to attempt in good faith to resolve such dispute. If such matter cannot be resolved by discussion of the Executives within ten (10) days following such meeting (as may be extended by mutual written agreement), such dispute shall be resolved in accordance with Section 12.3(c). For avoidance of doubt, any disputes, controversies or differences arising from the JSC pursuant to Article 2 shall be resolved solely in accordance with Section 2.1.

(c) Arbitration.

(i) If the parties do not resolve a dispute as provided in Section 12.3(b), and a party wishes to pursue the matter, each such dispute that is not an “Excluded Claim” shall be resolved by binding arbitration in accordance with the Rules of Arbitration of the International Chamber of Commerce (“ICC”) as then in effect (the “ICC Rules”), and judgment on the arbitration award may be entered in any court having jurisdiction thereof. The decision rendered in any such arbitration will be final and not appealable. If either party intends to commence binding arbitration of such dispute, such party will provide written notice to the other party informing the other party of such intention and the issues to be resolved. Within thirty (30) days after the receipt of such notice, the other party may by written notice to the party initiating binding arbitration, add additional issues to be resolved.

(ii) The arbitration shall be conducted by a panel of three (3) arbitrators experienced in the pharmaceutical business, none of whom shall be a current or former employee or director, or a then-current stockholder, of either party, their respective Affiliates or any Sublicensee. Within thirty (30) days after receipt of the original notice of binding arbitration, each party shall select one person to act as arbitrator and the two party-selected arbitrators shall select a third arbitrator within ten (10) days of their appointment. If the arbitrators selected by the parties are unable or fail to agree upon the third arbitrator, the third arbitrator shall be appointed by the ICC in accordance with the ICC Rules. The place of arbitration shall be New York, New York, and all proceedings and communications shall be in English.

(iii) It is the intention of the parties that discovery, although permitted as described herein, will be limited except in exceptional circumstances. The arbitrators will permit such limited discovery necessary for an understanding of any legitimate issue raised in the arbitration, including the production of documents. No later than thirty (30) days after selection of the arbitrators, the parties and their representatives shall hold a preliminary meeting with the arbitrators, to mutually agree upon and thereafter follow procedures seeking to assure that the arbitration will be concluded within six (6) months from such meeting. Failing any such mutual agreement, the arbitrators will design and the parties shall follow procedures to such effect.

37

(iv) Either party may apply to the arbitrators for interim injunctive relief until the arbitration award is rendered or the controversy is otherwise resolved. Either party also may, without waiving any remedy under this Agreement, seek from any court having jurisdiction any injunctive or provisional relief necessary to protect the rights or property of that party pending the arbitration award. The arbitrators shall have no authority to award punitive or any other non-compensatory damages. The arbitrators shall have the power to order that all or part of the legal or other costs incurred by a party in connection with the arbitration be paid by the other party. Subject to the preceding sentence, each party shall bear an equal share of the arbitrators’ and any administrative fees of arbitration.

(v) Except to the extent necessary to confirm or enforce an award or as may be required by applicable law, neither a party nor an arbitrator may disclose the existence, content, or results of an arbitration without the prior written consent of both parties. In no event shall an arbitration be initiated after the date when commencement of a legal or equitable proceeding based on the dispute, controversy or claim would be barred by the applicable New York statute of limitations.

(vi) As used in this Section, the term “Excluded Claim” shall mean a dispute, controversy or claim that concerns (A) the validity, enforceability or infringement of a patent, trademark, copyright or regulatory data exclusivity; or (B) any antitrust, anti-monopoly or competition law or regulation, whether or not statutory.

12.4 Entire Agreement; Modification. This Agreement, including the Exhibits hereto, is both a final expression of the parties’ agreement and a complete and exclusive statement with respect to all of its terms. Except for the U.S. Agreement, the Services Agreement and the separate letter agreement between the parties, this Agreement supersedes all prior and contemporaneous agreements and communications, whether oral, written or otherwise, concerning any and all matters contained herein and therein, including the Confidentiality Agreement. This Agreement may only be modified or supplemented in a writing expressly stated for such purpose and signed by the parties to this Agreement.

12.5 Relationship Between the Parties. The parties’ relationship, as established by this Agreement, is solely that of independent contractors. This Agreement does not create any partnership, joint venture or similar business relationship between the 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.

12.6 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. Any waiver by a party of a particular provision or right shall be in writing, shall be as to a particular matter and, if applicable, for a particular period of time and shall be signed by such party.

12.7 Assignment. Except as expressly provided hereunder, neither this Agreement nor any rights or obligations hereunder may be assigned or otherwise transferred by either party

38

without the prior written consent of the other party (which consent shall not be unreasonably withheld); provided, however, that either party may assign or otherwise transfer this Agreement and its rights and obligations hereunder without the other party’s consent:

(a) in connection with the transfer or sale of all or substantially all of the business or assets of such party relating to products for control or prevention of CMV infection to a Third Party, whether by merger, sale of stock, sale of assets or otherwise (a “Sale”), provided that in the event of a Sale (whether this Agreement is actually assigned or is assumed by the acquiring party by operation of law (e.g., in the context of a reverse triangular merger)), intellectual property rights of the acquiring party to such transaction (if other than one of the parties to this Agreement) shall not be included in the technology licensed hereunder; or

(b) to an Affiliate, provided that the assigning party shall remain liable and responsible to the non-assigning party hereto for the performance and observance of all such duties and obligations by such Affiliate.

The rights and obligations of the parties under this Agreement shall be binding upon and inure to the benefit of the successors and permitted assigns of the parties. Any assignment not in accordance with this Agreement shall be void.

12.8 No Third Party Beneficiaries. This Agreement is neither expressly nor impliedly made for the benefit of any party other than those executing it, except as otherwise provided in this Agreement with respect to Astellas Indemnitees under Section 11.1 and Vical Indemnitees under Section 11.2.

12.9 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.

12.10 Cumulative Remedies. No remedy referred to in this Agreement is intended to be exclusive, but each shall be cumulative and in addition to any other remedy referred to in this Agreement or otherwise available under law.

12.11 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 or electronic mail (email) transmission 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 earliest of: (a) the date of actual receipt; (b) if mailed, five days after the date of postmark; or (c) if delivered by overnight courier, the next business day the overnight courier regularly makes deliveries.
