Fuso or GenVec, as the case may be, shall, be responsible for preparing, filing, prosecuting and maintaining of the patent applications and patents, solely owned by it, worldwide in such countries as it deems appropriate, and conducting any interferences, reexaminations, reissues, oppositions or requests for patent term extensions relating to the Fuso Technology or GenVec Technology (respectively), using counsel of its choice, at its expense; provided, such expenses may be included in the Research Program funding described in Section 2.3 of the Collaboration Agreement. 7.5.2 PATENT RIGHTS FOR JOINT TECHNOLOGY. (a) The parties will cooperate to file, prosecute and maintain patent applications covering the Joint Technology(ies) in the United States, European Union (in Europe through a European Patent Convention application) and Japan (collectively, the "Core Countries") and other countries agreed by the parties. The parties shall agree which party shall be responsible for conducting such activities with respect to a particular Joint Technology. The party conducting such activities shall keep the other party fully informed as to the status of such patent matters, including, without limitation, by providing the other party the opportunity, at the other party's expense, to review and comment on any documents relating to the Joint Technology which will be filed in any patent office at least thirty (30) days before such filing, and promptly providing the other party copies of any documents relating to Joint Technology which the party conducting such activities receives from such patent offices, including notice of all interferences, reissues, reexaminations, oppositions or requests for patent term extensions. The parties will share equally all expenses and fees associated with the filing, prosecution, issuance and maintenance of any patent application and resulting patent for a Joint Technology in the Core Countries and other agreed countries and such amounts shall be included within the Research Program funding described in Section 2.3 of the Collaboration Agreement. - 15 - <Page> (b) In the event that either party wishes to seek patent protection with respect to any Joint Technology outside the Core Countries, it shall notify the other party hereto. If both parties wish to seek patent protection with respect to such Joint Technology in such country or countries, activities shall be subject to Section 7.2.2(a) above. If only one party wishes to seek patent protection with respect to such Joint Technology in such country or countries, it may file, prosecute and maintain patent applications and patents with respect thereto, at its own expense. In any such case, the party declining to participate in such activities shall not grant any third party a license under its interest in the applicable Joint Technology in the applicable country or countries without the prior written consent of the other party, which consent shall not be unreasonably withheld. 7.6 ENFORCEMENT. 7.6.1 SOLELY OWNED TECHNOLOGY. Subject to 7.3.2 below, in the event that any GenVec Technology or Fuso Technology (in this Section, both referred to as "Technology") necessary for manufacture, use and sale of a Collaboration Product is infringed or misappropriated by a third party in any country in the Territory, or is subject to a declaratory judgment action arising from such infringement in such country, Fuso or GenVec, as the case may be, shall promptly notify the other party hereto. The party which owns or controls such Technology (the "Owner") shall have the initial right (but not the obligation) to enforce such Technology, or defend any declaratory judgment action with respect thereto, at its expense. In the event that the Owner fails to initiate a suit to enforce such Technology against a commercially significant infringement in the Field by a third party in any jurisdiction in the Territory within * of a request by the other party (the "Licensee") to do so, Licensee may, subject to the Owner's agreements with third parties, initiate such suit in the name of the Owner of such Technology against such infringement, at the expense of such Licensee. The party involved in any such claim, suit or proceeding, shall keep the other party hereto reasonably informed of the progress of any such claim, suit or proceeding. Any recovery by such party received as a result of any such claim, suit or proceeding shall be used first to reimburse such party for all expenses (including attorneys and professional fees) incurred in connection with such claim, suit or proceeding and if the party initiating the suit was the owner of the subject Technology, all of the remainder shall be retained by such owner, and if the party initiating the suit is the Licensee, * percent (*%) of the remainder shall be paid to the owner of the subject Technology and * percent (*%) retained by the Licensee. If the Licensee initiates such suit in the name of the Owner of such Technology against such infringement, the Licensee shall not enter into any agreement which makes any admission regarding (i) wrongdoing on the part the Owner, or (ii) the invalidity, unenforceability or absence of infringement of the Owner's Technology, without the prior written consent of the Owner, which consent shall not be unreasonably withheld. The parties shall cooperate with each other in connection with any such claim, suit or proceeding and shall keep each other reasonably informed of all material developments in connection with any such claim, suit or proceeding. 7.6.2 JOINTLY OWNED TECHNOLOGY. Notwithstanding 7.3.1 above, in the event that any technology that is jointly owned by GenVec and Fuso under Section 7.1 of this Agreement is infringed or misappropriated by a third party, Fuso and GenVec shall discuss whether, and, if so, how, to enforce such Joint Technology or defend such Joint Technology in an infringement action, declaratory judgment or other proceeding. In the event only one party wishes to participate in such - 16 - <Page> proceeding, it shall have the right to proceed alone, at its expense, and may retain any recovery; provided, at the request and expense of the participating party, the other party agrees to cooperate and join in any proceedings in the event that a third party asserts that the co-owner of such Joint Technology is necessary or indispensable to such proceedings. 7.7 INFRINGEMENT CLAIMS. If the manufacture, sale or use of any Collaboration Product in the Territory pursuant to this Agreement results in any claim, suit or proceeding alleging patent infringement against GenVec or Fuso, such party shall promptly notify the other party hereto. If Fuso is not named as a party in such a claim, suit or proceeding, Fuso may, at its own expense and through counsel of its own choice, seek leave to intervene in such claim, suit or proceeding. GenVec agrees not to oppose such intervention. If Fuso, and not GenVec, is named as a party to such claim, suit or proceeding, Fuso shall have the right to control the defense and settlement of such claim, suit or proceeding, at its own expense, using counsel of its own choice, however GenVec, at its own expense and through counsel of its own choice, may seek to intervene if the claim, suit or proceeding relates to the commercialization of the Collaboration Product in the Field, and in such event, Fuso agrees not to oppose such intervention. If Fuso is named as a party and GenVec shall, at any time, tender its defense to Fuso, then Fuso shall defend GenVec in such claim, suit or proceeding, at Fuso's own expense and through counsel of its own choice, and Fuso shall control the defense and settlement of any such claim, suit or proceeding; provided, Fuso shall not enter into any agreement which makes any admission regarding (i) wrongdoing on the part GenVec, or (ii) the invalidity, unenforceability or absence of infringement of any GenVec Patent Rights or patent claiming a Joint Technology, without the prior written consent of GenVec, which consent shall not be unreasonably withheld. The parties shall cooperate with each other in connection with any such claim, suit or proceeding and shall keep each other reasonably informed of all material developments in connection with any such claim, suit or proceeding. 8.

Each party hereto may disclose the other's Confidential Information to the extent such disclosure is reasonably necessary in connection with the conduct of the Research Program activities to be conducted at any academic institution approved by the Steering Committee, in filing or prosecuting patent applications, prosecuting or defending litigation, complying with applicable governmental regulations or otherwise submitting information to tax or other governmental authorities, conducting clinical trials, making a permitted sublicense, securing funding or otherwise exercising its rights hereunder, provided that if a party is required to make any such disclosure of another party's confidential information, other than pursuant to a confidentiality agreement, it will give reasonable advance notice to the latter party of such disclosure and, save to the extent inappropriate in the case of patent applications, will use its best efforts to secure confidential treatment of such information prior to its disclosure (whether through protective orders or otherwise). 9.3 NON-DISCLOSURE. Each of the parties hereto agrees not to disclose to any third party the financial terms of this Agreement without the prior written consent of each other party hereto, except to advisors, investors and others on a need to know basis under circumstances that reasonably ensure the confidentiality thereof, or to the extent required by law. Without limitation upon any provision of this Agreement, each of the parties hereto shall be responsible for the observance by its employees of the foregoing confidentiality obligations. Notwithstanding the foregoing, the parties shall agree upon a press release to announce the execution of this Agreement, together with a corresponding Q&A outline for use in responding to inquiries about the Agreement; thereafter, GenVec and Fuso may each disclose to third parties the information contained in such press release and Q&A without the need for further approval by the other. 10. INDEMNIFICATION 10.1 INDEMNIFICATION OF FUSO. GenVec shall indemnify and hold Fuso and its Affiliates, and their respective directors, officers, employees, agents and counsel, and the successors and assigns of the foregoing (the "Fuso Indemnitees"), harmless from and against any and all liabilities, damages, losses, costs or expenses (including reasonable attorneys' and professional fees and other expenses of litigation and/or arbitration) resulting from a claim, suit or proceeding brought by a third party against a Fuso Indemnitee, arising from or occurring as a result of: (i) GenVec's conduct of the Research Program, (ii) the development, manufacture, marketing and/or commercialization of any Collaboration Product by GenVec or its Affiliates or licensees other than Fuso and its Affiliates (including without limitation product liability claims), or (iii) the failure of Collaboration Products manufactured by GenVec to meet the relevant specifications, except, in each case, to the extent caused by the negligence or willful misconduct of Fuso. 10.2 INDEMNIFICATION OF GENVEC. Fuso shall indemnify and hold GenVec and its Affiliates and their respective directors, officers, employees, agents and counsel and the successors and assigns of the foregoing (the "GenVec Indemnitees"), harmless from and against any and all liabilities, damages, losses, costs or expenses (including reasonable attorneys' and professional fees and other expenses of litigation and/or arbitration) resulting from a claim, suit or proceeding brought by a third party against a GenVec Indemnitee, arising from or occurring as a result of; (i) Fuso's conduct of the - 19 - <Page> Research Program, or (ii) the development, manufacture, marketing and/or commercialization of any Collaboration Product by Fuso or its Affiliates or Sublicensees (including without limitation, product liability claims), except, in each case, to the extent caused by the negligence or willful misconduct of GenVec. 10.3 PROCEDURE. A party (the "Indemnitee") that intends to claim indemnification under this Article 10 shall promptly notify the other party (the "Indemnitor") in writing of any loss, claim, damage, liability or action in respect of which the Indemnitee or any of its Affiliates, Sublicensees or their directors, officers, employees, agents or counsel intend to claim such indemnification, and the Indemnitor shall have the right to participate in, and, to the extent the Indemnitor so desires, to assume the defense thereof with counsel mutually satisfactory to the parties. The indemnity agreement in this Article 10 shall not apply to amounts paid in settlement of any loss, claim, damage, liability or action if such settlement is made without the consent of the Indemnitor, which consent shall not be withheld unreasonably. The failure to deliver written notice to the Indemnitor within a reasonable time after the commencement of any such action, if prejudicial to its ability to defend such action, shall relieve such Indemnitor of any liability to the Indemnitee under this Article 10. At the Indemnitor's request, the Indemnitee under this Article 10, and its employees and agents, shall cooperate fully with the Indemnitor and its legal representatives in the investigation and defense of any action, claim or liability covered by this indemnification and provide full information with respect thereto. 11.

Either party may terminate this Agreement in the event the other party has materially breached or defaulted in the performance of any of its obligations hereunder, and such default has continued for sixty (60) days after written notice thereof was provided to the breaching party by the nonbreaching party. Any termination shall become effective at the end of such sixty (60) day period unless the breaching party has cured any such breach or default prior to the expiration of the sixty (60) day period. Notwithstanding the above, in the case of a failure to pay any amount due hereunder the period for cure of any such default following notice thereof shall be ten (10) days and, unless payment is made within such period, the termination shall become effective at the end of such period. 11.3 TERMINATION FOR INSOLVENCY.

Termination of this Agreement for any reason shall not release any party hereto from any liability which, at the time of such termination, has already accrued to the other party or which is attributable to a period prior to such termination, nor preclude either party from pursuing any rights and remedies it may have hereunder or at law or in equity which accrued or are based upon any event occurring prior to such termination. 11.6.2 RETURN OF MATERIALS. Upon any termination of this Agreement, Fuso and GenVec shall promptly return to the other party all materials and Confidential Information (except as provided in 11.1 above) received from the other party (except one copy of which may be retained by legal counsel for archival purposes); provided, however, that the foregoing shall only apply to GenVec in the event this Agreement is properly terminated by Fuso pursuant to Section 11.2 or 11.3. 11.6.3 STOCK ON HAND. In the event this Agreement is terminated for any reason, Fuso and its Affiliates and Sublicensees shall have the right to sell or otherwise dispose of the stock of any Collaboration Products then on hand subject to Articles 3 and 4 and the other applicable terms of this Agreement. 11.6.4 LICENSES.

DISPUTE RESOLUTION 12.1 MEDIATION. If a dispute arises out of or relates to this Agreement, or the breach thereof, and if said dispute cannot be settled through negotiation, the parties agree first to try in good faith to settle the dispute by mediation under the Commercial Mediation Rules of the American Arbitration Association before resorting to arbitration. 12.2 ARBITRATION. Any dispute under this Agreement (except any dispute relating to the validity or enforceability of any patent) which is not settled by mutual consent shall be finally settled by binding arbitration. Such arbitration shall be conducted in accordance with the International Arbitration Rules of the Asia/Pacific Center by three (3) arbitrators appointed in accordance with said rules and held in San Francisco, California. At least one of the arbitrators shall be an independent expert in pharmaceutical product development (including clinical development and regulatory affairs). The arbitrators shall determine what discovery will be permitted, consistent with the goal of limiting the cost and time which the parties must expend for discovery; provided the arbitrators shall permit such discovery as they deem necessary to permit an equitable resolution of the dispute. Any written evidence originally in a language other than English shall be submitted in English translation accompanied by the original or a true copy thereof. The costs of the arbitration including administrative and arbitrators' fees, shall be shared equally by the parties and each party shall bear its own costs and attorneys' and witness' fees incurred in connection with the arbitration. A disputed performance or suspended performances pending the resolution of the arbitration must be completed within thirty (30) days following the final decision of the arbitrators or such other reasonable period as the arbitrators determine in a written opinion. Any arbitration subject to this Article shall be completed within one (1) year from the filing of notice of a request for such arbitration. No punitive damages may be granted by the arbitrators. The arbitration proceedings and the decision shall not be made public without the joint consent of the parties and each party shall maintain the confidentiality of such proceedings and decision unless otherwise permitted by the other party.

Neither party may waive or release any of its rights or interests in this Agreement except in writing. The failure of either party to assert a right hereunder or to insist upon compliance with any term or condition of this Agreement shall not constitute a waiver of that right or excuse a similar subsequent failure to perform any such term or condition. 13.3 ASSIGNMENT. This Agreement shall not be assignable by either party to any third party hereto without the written consent of the other party hereto; except either party may assign this Agreement, without such consent, to (i) an Affiliate of such party; or (ii) an entity that acquires all or substantially all of the business or assets of such party to which this Agreement pertains, whether by merger, reorganization, acquisition, sale, or otherwise and that agrees in writing to be strictly bound by the terms and conditions of this Agreement. The terms and conditions of this Agreement shall be binding on and inure to the benefit of the permitted successors and assigns of the parties. 13.4 NOTICES.

Neither party shall be liable to the other for failure or delay in the performance of any of its obligations under this Agreement for the time and to the extent such failure - 23 - <Page> or delay is caused by earthquake, riot, civil commotion, war, hostilities between nations, governmental law, order or regulation, embargo, action by the government or any agency thereof, act of God, storm, fire, accident, labor dispute or strike, sabotage, explosion or other similar or different contingencies, in each case, beyond the reasonable control of the respective party. The party affected by force majeure shall provide the other party with full particulars thereof as soon as it becomes aware of the same (including its best estimate of the likely extent and duration of the interference with its activities), and will use its best endeavors to overcome the difficulties created thereby and to resume performance of its obligations as soon as practicable. If the performance of any obligation under this Agreement is delayed owing to a force majeure for any continuous period of more than six (6) months, the parties hereto shall consult with respect to an equitable solution including the possible termination of this Agreement. 13.7 INDEPENDENT CONTRACTORS.

In the event that any provisions of this Agreement are determined to be invalid or unenforceable by a court of competent jurisdiction, the remainder of the Agreement shall remain in full force and effect without said provision. The parties shall in good faith negotiate a substitute clause for any provision declared invalid or unenforceable, which shall most nearly approximate the intent of the parties in entering this Agreement; provided, if the parties are unable to agree on such a substitute clause and the deletion of the provision held invalid or unenforceable would produce material adverse financial consequences for one party, such party shall have the right to terminate the Agreement with one hundred eighty (180) days notice. 13.12 PATENT MARKING. Fuso agrees to mark and have its Affiliates and Sublicensees mark all Collaboration Products they sell or distribute pursuant to this Agreement in accordance with the applicable statute or regulations in the country or countries of manufacture and sale thereof. - 24 - <Page> 13.13 FURTHER ASSURANCES.
