HGS agrees that all RESEARCH PLANS submitted by TRANSGENE pursuant to this Agreement shall be strictly confidential. HGS further agrees that all such RESEARCH PLANS will not be utilized by or on behalf of HGS for any other purpose. 8. PATENT PROSECUTION AND LITIGATION 8.1. Each party shall have and retain sole and exclusive title to all inventions, discoveries, designs, works of authorship and other know-how which are made, conceived, reduced to practice or generated by its employees, agents, or other persons acting under its authority. As to all inventions, discoveries, designs, works of authorship and other know-how made, conceived, reduced to practice or generated jointly by the respective employees, agents, or other persons acting under the authority of HGS and TRANSGENE, the parties shall own an equal undivided interest therein. In the event of jointly owned inventions, HGS shall be responsible for the filing, prosecution and maintenance of patents and patent applications directed thereto under the terms and conditions of Paragraph 8.2, however, each of HGS and TRANSGENE shall be responsible for an equal share of the cost and expense thereof. HGS shall consult with TRANSGENE with respect to strategies for filing, prosecution and maintenance of patents and patent applications for which it bears responsibility under this Paragraph 8.1, and shall keep TRANSGENE reasonably informed with regard to filing, prosecution and maintenance activity for such joint patents and patent applications, provided, however, that HGS shall have final decision-making authority with respect to filing, prosecution and maintenance of any patents and patent applications for which it is responsible. If a joint owner does not desire to file, prosecute or maintain a patent or patent application to a joint invention, such owner shall assign its ownership interest therein to the other joint owner and shall no longer be responsible for the cost and * Confidential treatment requested 22 <PAGE> 26 expense thereof, and shall have no further right to consult, review or comment with respect to the filing, prosecution and maintenance of said patent or patent application. All patents and patent applications to joint inventions which are LICENSED TECHNOLOGY and/or TRANSGENE TECHNOLOGY shall be LICENSED PATENTS and TRANSGENE PATENTS, respectively, subject to the terms and conditions of this Agreement; otherwise, any joint owner shall be free to dispose of its interest therein without accounting to any other owner. 8.2. (a) HGS shall have the right within its sole discretion to prepare, file, prosecute and maintain LICENSED PATENTS solely owned by HGS. With respect to LICENSED PATENTS as to which TRANSGENE obtains a license hereunder, subject to Paragraph 8.9, HGS shall keep TRANSGENE reasonably informed with respect to the filing and prosecution thereof (including interference proceedings). In the event that HGS does not intend to prepare, file, prosecute and/or maintain patent protection in any country with respect to LICENSED TECHNOLOGY other than expressed sequence tags (ESTs) as to which TRANSGENE obtains a license hereunder, HGS shall, at TRANSGENE's option, do so at the cost and expense of TRANSGENE. In the event that a THIRD PARTY who has entered into an agreement with HGS as contemplated by Paragraph 2.10(a) also makes such a request in a country, such costs shall be apportioned between TRANSGENE and such THIRD PARTY. (b) TRANSGENE shall have the right within its sole discretion to prepare, file, prosecute and maintain TRANSGENE PATENTS solely owned by TRANSGENE. With respect to TRANSGENE PATENTS, TRANSGENE shall keep HGS reasonably informed with respect to the filing and prosecution thereof (including interference proceedings). In the event that TRANSGENE does not intend to prepare, file, prosecute and/or maintain patent protection in any country with respect to TRANSGENE TECHNOLOGY as to which HGS retains a license hereunder, TRANSGENE shall, at HGS' option, do so at the cost and expense of HGS. (c) TRANSGENE will provide HGS reasonable assistance to enable HGS to prepare, file, prosecute and maintain LICENSED PATENTS pursuant to Paragraph 8.2(a). HGS will 23 <PAGE> 27 provide TRANSGENE reasonable assistance to enable TRANSGENE to prepare, file, prosecute and maintain TRANSGENE PATENTS pursuant to Paragraph 8.2(b). 8.3. Notwithstanding Paragraphs 8.1 and 8.2, for each LICENSED PATENT (including patents on joint inventions) that covers an EXCLUSIVE TRANSGENE PRODUCT, HGS may request that TRANSGENE assume responsibility for the prosecution (including interferences or appeals) and maintenance of such LICENSED PATENT, and, if so requested, TRANSGENE may elect to assume such responsibility. If TRANSGENE elects to assume such responsibility, (I) TRANSGENE shall be responsible for all future costs associated with the filing, prosecution (including interferences or appeals) and maintenance of such LICENSED PATENT, (ii) TRANSGENE shall reimburse HGS for all costs incurred by HGS subsequent to TRANSGENE's obtaining an exclusive license to the covered EXCLUSIVE TRANSGENE PRODUCT pursuant to Paragraph 2.4; and (iii) HGS shall promptly transfer such patents or patent applications to TRANSGENE for further filing, prosecution and maintenance. 8.4. (a) In the event of the institution of any suit by a THIRD PARTY against TRANSGENE or its licensees for patent infringement involving the manufacture, use, import, export, offer for sale, sale, distribution or marketing of TRANSGENE PRODUCT, TRANSGENE shall promptly notify HGS in writing. As between HGS and TRANSGENE, TRANSGENE shall be solely responsible for the cost and expense of such action and any liability which results therefrom. (b) In the event of the institution of any suit by a THIRD PARTY against HGS or its licensees, for patent infringement involving the manufacture, use, import, export, offer for sale, sale, distribution or marketing of any product sold by HGS or its licensees involving or developed using LICENSED TECHNOLOGY and/or TRANSGENE TECHNOLOGY, HGS shall promptly notify TRANSGENE in writing. As between HGS and TRANSGENE, HGS shall be solely responsible for the cost and expense of such action and any liability which results therefrom. 24 <PAGE> 28 (c) The party defending an action under this Paragraph 8.4 shall have full control over its conduct, including settlement thereof provided such settlement shall not be made without the prior written consent of the other licensing party or licensed party if it would adversely affect the patent rights of such party. 8.5. In the event that HGS or TRANSGENE becomes aware of actual or threatened infringement of a TRANSGENE PATENT, or a LICENSED PATENT covering an EXCLUSIVE TRANSGENE PRODUCT, anywhere in the TERRITORY, that party shall promptly notify the other party in writing. The owner of the TRANSGENE PATENT or LICENSED PATENT, and HGS in the case of a joint patent, shall have the first right but not the obligation to bring, at its own expense, an infringement action against any THIRD PARTY and to use the other party's name in connection therewith. If the owner of the patent does not commence a particular infringement action within * days, the other party, after notifying the owner in writing, shall be entitled to bring such infringement action, in its own name and/or in the name of the patent owner, at its own expense to the extent that such party is licensed thereunder. The foregoing notwithstanding, in the event that an alleged infringer certifies pursuant to 21 U.S.C. Section 355(b)(2)(A)(iv) against an issued TRANSGENE PATENT or LICENSED PATENT covering an EXCLUSIVE TRANSGENE PRODUCT, as between the patent owner and the owner of the product, the party receiving notice of such certification shall immediately notify the other party of such certification, and if fourteen (14) days prior to expiration of the forty five (45) day period set forth in 21 U.S.C. Section 355(c)(3)(C), the owner of the TRANSGENE PATENT or LICENSED PATENT fails to commence an infringement action, the party receiving notice, in its sole discretion, at its own expense and to the extent that it is licensed under the TRANSGENE PATENT or LICENSED PATENT, shall be entitled to bring such infringement action in its own name and/or in the name of the patent owner. The party conducting an action under this Paragraph 8.5 shall have full control over its conduct, including settlement thereof provided such settlement shall not be made without the prior written consent of the other licensing party or * Confidential treatment requested 25 <PAGE> 29 licensed party if it would adversely affect the patent rights of such party. The licensing party (i.e., the patent owner) and the licensed party (e.g., the owner of the product) shall reasonably assist one another and cooperate in any such litigation at the other's request, each such party paying its own costs and expenses. The party conducting the litigation shall periodically reimburse the other party for its reasonable and actual out-of-pocket expenses for assisting in the litigation, which reimbursement shall be made within thirty (30) days of receipt by the party conducting the litigation of itemized invoices from the assisting party documenting such expenses. 8.6. Any recovery made by a party as the result of an action for patent infringement it has conducted under Paragraph 8.5 shall be distributed as follows: (i) The party conducting the action shall recover its actual out -of-pocket expenses, and then shall reimburse the other party for any unreimbursed actual and out-of-pocket expenses. (ii) To the extent that the recovery exceeds the total of item (i), the excess shall be kept by the party conducting the action, provided, however, that to the extent that (a) the recovery is based on an award of lost sales/profits, and (b) the party conducting the action would have incurred a royalty obligation to the other party based upon such sales, the party to whom such royalties would have been due shall receive a proportion of the excess recovery corresponding to the royalty percentage it would have otherwise been due. 8.7. The parties shall periodically keep one another reasonably informed of the status of their respective activities regarding any such litigation or settlement thereof. 8.8. To the extent that the owner of a TRANSGENE PATENT or a LICENSED PATENT also owns a product (covered by an NDA or HRD) which product is covered by a granted claim of said TRANSGENE PATENT or LICENSED PATENT, the owner of said TRANSGENE PATENT or LICENSED PATENT shall have the first right to seek extensions of the terms of 26 <PAGE> 30 the patent and to seek to obtain SPCs. If the owner of a TRANSGENE PATENT or a LICENSED PATENT does not own a product covered by a granted claim of said TRANSGENE PATENT or LICENSED PATENT, then the owner of a product (covered by an NDA or HRD) which product is licensed under and is covered by a granted claim of said TRANSGENE PATENT or LICENSED PATENT shall have the right to seek extensions of the terms of the patent and to seek to obtain SPCs. Where more than one (1) product is covered by a granted claim of the same TRANSGENE PATENT or the same LICENSED PATENT, as between TRANSGENE and HGS, the right to seek extensions of the terms of the patent and to obtain SPCs shall be granted by the patent owner to the first of TRANSGENE, HGS or licensee of HGS, who is licensed thereunder, to submit to the patent owner, in writing, a request to obtain such rights with respect to a product (covered by an NDA or HRD) which is approved for marketing and/or sale in at least one country in which said TRANSGENE PATENT or LICENSED PATENT is in force. Each party shall assist the other in the obtaining of such extensions or SPCs including by authorizing the other party to act as its agent. 8.9. The obligations of HGS to keep TRANSGENE informed under Paragraph 8.2(a) shall only apply to LICENSED PATENTS which claim LICENSED TECHNOLOGY which directly relates to or covers an EXCLUSIVE TRANSGENE PRODUCT. 9. STATEMENTS AND REMITTANCES 9.1. TRANSGENE and HGS, as the case may be, shall keep and require its licensees to keep complete and accurate records of all NET SALES of EXCLUSIVE TRANSGENE PRODUCTS for which royalties are due hereunder. Each party shall have the right, at its expense, through a certified public accountant or like person reasonably acceptable to the other party, to examine pertinent financial records during regular business hours upon proper advance written notice during the life of this Agreement and for * months after its termination for the purpose of verifying and reporting to HGS or TRANSGENE as to the computation of the royalty * Confidential treatment requested 27 <PAGE> 31 payments made hereunder; provided, however, that such examination shall not take place more often than once a year; provided further that such accountant shall report only as to the accuracy of the royalty statements and payments, including the magnitude and source of any discrepancy. TRANSGENE, HGS, and their licensees shall be required to maintain such records for three (3) years. The accountant shall execute customary confidentiality agreements prior to any examination, reasonably satisfactory in form and substance to both parties, to maintain in confidence all information obtained during the course of any such examination, except for disclosure to the parties, as necessary for the above purpose. 9.2. Within * days after the close of each calendar quarter, TRANSGENE and HGS, as the case may be, shall deliver to the other party a true accounting of all EXCLUSIVE TRANSGENE PRODUCTS subject to royalty hereunder sold by it and its licensees and distributors during such calendar quarter and shall at the same time pay all royalties due, including monies owed under Paragraph 3.8. 9.3. All royalties and other payments due under this Agreement shall be payable in U.S. dollars. 9.4. Royalties payable on sales in countries other than the United States shall be calculated by multiplying the appropriate royalty rate times the sales in each currency in which they are made and converting the resulting amount into United States dollars, at the rates of exchange as reported in The New York Times, or, if not in the Times, then in The Wall Street Journal, on the last business day in New York, New York of each royalty period. Such payments shall be without deduction of exchange, collection, or other changes. If, due to restrictions or prohibitions imposed by a national or international authority, payments cannot be made as aforesaid, the parties shall consult with a view to finding a prompt and acceptable solution, and the parties will deal with such monies as the other party may lawfully direct at no additional out-of-pocket expense to the party owed the royalty. Notwithstanding the foregoing, if royalties cannot be remitted for any reason within * months after the end of the calendar quarter during which * Confidential treatment requested 28 <PAGE> 32 they are earned, then the party owing the royalty shall be obligated to deposit the royalties in a bank account in Switzerland in the name of the other party. Each party shall deduct any taxes which the party is obligated to pay and/or withhold in a country based on royalties due to the other based on sales in such country from royalty payments due for such country under this Agreement and pay them to the proper authorities as required by applicable laws. Each party shall maintain official receipts of payment of any such taxes and forward these receipts to the other within * days. 10. TERM AND TERMINATION 10.1. This Agreement shall come into effect as of the date first written above, and shall remain in full force and effect unless earlier terminated as provided in this Section 10, provided, that, except for the provisions of Paragraph 10.2 and Section 12, the rights and obligations of the parties hereunder shall be contingent upon the closing of the initial public offering described in Paragraph 10.2 hereof. 10.2. HGS may terminate this Agreement immediately, effective upon written notice to TRANSGENE, in the event that TRANSGENE does not complete an underwritten initial public offering of at least twenty five million U.S. dollars ($25,000,000) at a post-money valuation of at least one hundred fifteen million U.S. dollars ($115,000,000) on or before July 31, 1998. However, the parties recognize the volatility of capital markets, and therefore agree to discuss possible alternative financial arrangements in the event an underwritten initial public offering has not occurred on or before July 31, 1998, provided that if the parties fail to reach agreement and HGS exercises its right to terminate pursuant to Paragraph 10.2, TRANSGENE's payment obligation pursuant to Paragraph 3.1 shall terminate. 10.3. (a) Subject to Paragraph 10.5, in the event TRANSGENE fails to make a royalty or milestone payment to HGS under this Agreement with respect to an EXCLUSIVE TRANSGENE PRODUCT, when due, or fails to meet its obligations under Section 5 of this * Confidential treatment requested 29 <PAGE> 33 Agreement with respect to an EXCLUSIVE TRANSGENE PRODUCT, in addition to any other remedy which it may have, HGS may notify TRANSGENE in writing that (i) all TRANSGENE's rights with respect to such EXCLUSIVE TRANSGENE PRODUCT shall terminate as of sixty (60) days after such written notice and TRANSGENE's rights with respect thereto shall terminate unless such payment is made or such failure is cured, prior to the expiration of such sixty (60) day period; or (ii) if TRANSGENE has previously failed twice to make a royalty or milestone payment to HGS under this Agreement or to meet its obligations under Section 5 of this Agreement, HGS may notify TRANSGENE in writing that this Agreement shall terminate in its entirety, and if TRANSGENE fails to cure such failure within sixty (60)days thereafter, this Agreement shall terminate in its entirety. 10.4. In the event that TRANSGENE fails to make the payment to HGS under Paragraph 3.1 when due, in addition to any other remedy which HGS may have, HGS may notify TRANSGENE in writing of such failure and the termination of this Agreement in its entirety, and if TRANSGENE fails to make such payment within thirty (30) days thereafter, this Agreement shall terminate. 10.5. Notwithstanding Paragraph 10.3, HGS may not terminate TRANSGENE's rights or this Agreement, if TRANSGENE reasonably contests whether such royalty or milestone is due or reasonably contests that it has not failed to meet its obligations under Section 5 of this Agreement and provided TRANSGENE has instituted an arbitration proceeding pursuant to Paragraph 15.3. 10.6. In the event that HGS fails to meet its obligations under Section 4, in addition to any other remedy which TRANSGENE may have, TRANSGENE may notify HGS of such failure and that this Agreement shall terminate in its entirety, and if HGS fails to cure such failure within thirty (30) days thereafter, this Agreement shall terminate in its entirety. 10.7. In the event HGS fails to make a royalty payment to TRANSGENE under this Agreement with respect to an EXCLUSIVE TRANSGENE PRODUCT, when due, or fails to 30 <PAGE> 34 meet its obligations under Section 5 of this Agreement with respect to an EXCLUSIVE TRANSGENE PRODUCT, in addition to any other remedy which it may have, TRANSGENE may notify HGS in writing that all HGS' rights with respect to such EXCLUSIVE TRANSGENE PRODUCT shall terminate as of sixty (60) days after such written notice and HGS' rights with respect thereto shall terminate unless such payment is made or such failure is cured, prior to the expiration of such sixty (60) day period. Notwithstanding the foregoing, TRANSGENE may not terminate HGS' rights, if HGS reasonably contests whether such royalty is due or reasonably contests that it has not failed to meet its obligations under Section 5 of this Agreement and provided HGS has instituted an arbitration proceeding pursuant to Paragraph 15.3. 10.8. Either party, may terminate this Agreement if, at any time, the other party shall file in any court or agency pursuant to any statute or regulation of any state or country, a petition in bankruptcy or insolvency or for reorganization or for an arrangement or for the appointment of a receiver or trustee of the party or of its assets, or if the other party proposes a written agreement of composition or extension of its debts, or if the other party shall be served with an involuntary petition against it, filed in any insolvency proceeding, and such petition shall not be dismissed within sixty (60) days after the filing thereof, or if the other party shall propose or be a party to any dissolution or liquidation, or if the other party shall make an assignment for the benefit of creditors. 10.9. Neither party shall have the right to terminate this Agreement except under Paragraphs 10.2, 10.3, 10.4, 10.6 and 10.8, provided however that nothing in this Agreement shall limit any remedies for breach which may be available pursuant to a judgment of a court, in law or equity, including termination of this Agreement or of any or all rights hereunder, except that any action seeking remedies for breach of this Agreement shall be conducted in accordance with Section 15. 31 <PAGE> 35 11. RIGHTS AND DUTIES UPON TERMINATION 11.1. Notwithstanding termination of this agreement, the rights and obligations of the parties under Sections 7, 9, 11, 13 and 15, and Paragraphs 2.4(a) and (b), 2.7 and 2.8, shall survive such termination. 11.2. Termination of the Agreement in accordance with the provisions hereof shall not limit remedies which may be otherwise available in law or equity. 11.3. Other than termination of this Agreement pursuant to Paragraph 10.8 or with respect to a TRANSGENE PRODUCT as to which rights have been terminated under Paragraph 10.3, TRANSGENE's obligation to pay royalties and milestone payments for EXCLUSIVE TRANSGENE PRODUCTS shall survive such termination, and HGS' obligations to pay royalties for EXCLUSIVE TRANSGENE PRODUCTS shall survive such termination. 11.4. In the event that this Agreement is terminated by HGS pursuant to Paragraphs 10.2, 10.3, 10.4 or 10.8, all rights to TRANSGENE TECHNOLOGY, TRANSGENE PATENTS and TRANSGENE PRODUCTS shall revert to HGS and HGS shall be the sole owner of such technology, patents and products. 12. WARRANTIES AND REPRESENTATIONS 12.1. Each of HGS and TRANSGENE hereby represents, warrants and covenants to the other, as of the date of this Agreement, as follows: (a) it is a corporation duly organized and validity existing under the laws of the state or other jurisdiction of incorporation or formation; (b) the execution, delivery and performance of this Agreement by such party has been duly authorized by all requisite corporate action; 32 <PAGE> 36 (c) it has the power and authority to execute and deliver this Agreement and to perform its obligations hereunder, including, without limitation, the right, power and authority to grant the licenses under Section 2; (d) the execution, delivery and performance by such party of this Agreement and its compliance with the terms and provisions hereof to such party's best knowledge does not conflict with or result in a breach of any of the terms and provisions of or constitute a default under (i) a loan agreement, guaranty, financing agreement, agreement affecting a product or other agreement or instrument binding or affecting it or its property; (ii) the provisions of its charter documents or bylaws; or (iii) any order, writ, injunction or decree of any court or governmental authority entered against it or by which any of its property is bound; (e) this Agreement constitutes such party's legal, valid and binding obligation enforceable against it in accordance with its terms subject, as to enforcement, to bankruptcy, insolvency, reorganization and other laws of general applicability relating to or affecting creditors' rights and to the availability of particular remedies under general equity principles. 12.2. No party to this Agreement has in effect, and, after the date of this Agreement, no party shall enter into any written agreement that would be inconsistent with its obligations under this Agreement. 12.3. Because this Agreement is a collaboration agreement as permitted by Section 2.11(a) of the Gene Therapy Collaboration and License Agreement with Schering, (the "Schering Gene Therapy Agreement"), HGS represents and warrants that TRANSGENE's right to obtain an exclusive license to an EXCLUSIVE TRANSGENE PRODUCT pursuant to Paragraph 2.5 of this Agreement is not subject to those rights of Schering specified in Section 2.11(b) of the Schering Gene Therapy Agreement. 33 <PAGE> 37 12.4. NOTHING IN THIS AGREEMENT SHALL BE CONSTRUED AS A WARRANTY THAT TRANSGENE PATENTS OR LICENSED PATENTS ARE VALID OR ENFORCEABLE OR THAT THEIR EXERCISE OR THE EXERCISE OF LICENSED TECHNOLOGY OR TRANSGENE TECHNOLOGY DOES NOT INFRINGE ANY PATENT RIGHTS OF THIRD PARTIES. A HOLDING OF INVALIDITY OR UNENFORCEABILITY OF ANY SUCH PATENT, FROM WHICH NO FURTHER APPEAL IS OR CAN BE TAKEN, SHALL NOT AFFECT ANY OBLIGATION HEREUNDER, BUT SHALL ONLY ELIMINATE ROYALTIES OTHERWISE DUE UNDER SUCH PATENT FROM THE DATE SUCH HOLDING BECOMES FINAL. 12.5. EXCEPT AS OTHERWISE EXPRESSLY SET FORTH HEREIN HGS AND TRANSGENE MAKE NO REPRESENTATIONS OR EXTEND ANY WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. 12.6. Each party represents and warrants to the other parties hereto that any materials provided by one party to another under this Agreement shall be used in compliance with all applicable laws and regulations. 12.7. No claim can be made or shall exist with respect to a breach of warranty, representation or covenant under Paragraph 12.1(a); (b), (d) or (e), unless such claim is made prior to the end of the RESEARCH TERM. 13. INDEMNIFICATION 13.1. TRANSGENE shall defend, indemnify and hold harmless HGS, licensors of HGS and each of their respective directors, officers, shareholders, agents and employees, from and against any and all liability, loss, damages and expenses (including reasonable attorneys' fees) as the result of claims, demands, costs or judgments which may be made or instituted against any of them arising out of the manufacture, possession, distribution, use, testing, sale or other 34 <PAGE> 38 disposition of any EXCLUSIVE TRANSGENE PRODUCT by or through TRANSGENE or any THIRD PARTY granted rights by TRANSGENE under this Agreement. TRANSGENE's obligation to defend, indemnify and hold harmless shall include claims, demands, costs or judgments, whether for money damages or equitable relief by reason of alleged personal injury (including death) to any person or alleged property damage, provided, however, the indemnity shall not extend to any claims against an indemnified party which result from the gross negligence or willful misconduct of such indemnified party. TRANSGENE shall have the exclusive right to control the defense of any action which is to be indemnified in whole by TRANSGENE hereunder, including the right to select counsel reasonably acceptable to HGS to defend HGS, and to settle any claim, provided that, without the written consent of HGS (which shall not be unreasonably withheld or delayed), TRANSGENE shall not agree to settle any claim against HGS to the extent such claim has a material adverse effect on HGS. The provisions of this paragraph shall survive and remain in full force and effect after any termination, expiration or cancellation of this Agreement and the obligation hereunder shall apply whether or not such claims are rightfully brought. TRANSGENE shall require each licensee to agree to indemnify HGS, in a manner consistent with this Paragraph 13.1. 13.2. HGS shall defend, indemnify and hold harmless TRANSGENE, licensors of TRANSGENE and each of their respective directors, officers, shareholders, agents and employees, from and against any and all liability, loss, damages and expenses (including reasonable attorneys' fees) as the result of claims, demands, costs or judgments which may be made or instituted against any of them arising out of the manufacture, possession, distribution, use, testing, sale or other disposition by or through HGS or any THIRD PARTY granted rights by HGS under this Agreement of any product in the HGS FIELD as to which HGS is granted a license under a TRANSGENE PATENT or TRANSGENE TECHNOLOGY. HGS' obligation to defend, indemnify and hold harmless shall include claims, demands, costs or judgments, whether for money damages or equitable relief by reason of alleged personal injury (including death) to 35 <PAGE> 39 any person or alleged property damage, provided, however, the indemnity shall not extend to any claims against an indemnified party which result from the gross negligence or willful misconduct of such indemnified party. HGS shall have the exclusive right to control the defense of any action which is to be indemnified in whole by HGS hereunder, including the right to select counsel reasonably acceptable to TRANSGENE to defend TRANSGENE and to settle any claim, provided that, without the written consent of TRANSGENE (which shall not be unreasonably withheld or delayed), HGS shall not agree to settle any claim against TRANSGENE to the extent such claim has a material adverse effect on TRANSGENE. The provisions of this paragraph shall survive and remain in full force and effect after any termination, expiration or cancellation of this Agreement and HGS' obligation hereunder shall apply whether or not such claims are rightfully brought. HGS shall require each licensee to agree to indemnify TRANSGENE in a manner consistent with this Paragraph 13.2. 13.3. A person or entity that intends to claim indemnification under this Section 13 (the "Indemnitee") shall promptly notify the other party (the "Indemnitor") of any loss, claim, damage, liability, or action in respect of which the Indemnitee intends to claim such indemnification, and the Indemnitor, after it determines that indemnification is required of it, shall assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an Indemnitee shall have the right to retain its own counsel, with the fees and expenses to be paid by the Indemnitor if Indemnitor does not assume the defense; or, if representation of such Indemnitee by the counsel retained by the Indemnitor would be inappropriate due to actual or potential differing interests between such Indemnitee and any other party represented by such counsel in such proceedings. The indemnity agreement in this Section 13 shall not apply to amounts paid in settlement of any loss, claim, damage, liability or action if such settlement is effected without the consent of the Indemnitor, which consent shall not be withheld unreasonably. The failure to deliver 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 36 <PAGE> 40 such Indemnitor of any liability to the Indemnitee under this Section 13, but the omission so to deliver notice to the Indemnitor will not relieve it of any liability that it may have to any Indemnitee otherwise than under this Section 13. The Indemnitee under this Section 13, its employees and agents, shall cooperate fully with the Indemnitor and its legal representatives in the investigations of any action, claim or liability covered by this indemnification. In the event that each party claims indemnity from the other and one party is finally held liable to indemnify the other, the Indemnitor shall additionally be liable to pay the reasonable legal costs and attorneys' fees incurred by the Indemnitee in establishing its claim for indemnity. 14. FORCE MAJEURE 14.1. If the performance of any party of this Agreement, or of any obligation under this Agreement, is prevented, restricted, interfered with or delayed by reason of any cause beyond the reasonable control of the party liable to perform, the party so affected shall, upon giving written notice to the other party, be excused from such performance to the extent of such prevention, restriction, interference or delay, provided that the affected party shall use its reasonable best efforts to avoid or remove such causes of non-performance and shall continue performance with the utmost dispatch whenever such causes are removed. When such circumstances arise, the parties shall discuss what, if any, modification of the terms of this Agreement may be required in order to arrive at an equitable solution. 15. DISPUTE RESOLUTION 15.1. This Agreement shall be construed and enforced in accordance with the laws of the State of Delaware. 15.2. In the event of any controversy or claim arising out of or relating to any provision of this Agreement or the breach thereof, the parties shall try to settle those conflicts amicably between themselves. 37 <PAGE> 41 15.3. Should the parties fail to agree, any controversy, dispute or claim which may arise out of or in connection with this Agreement, or the breach, termination or validity thereof other than with respect to patent validity shall be settled by final and binding arbitration pursuant to the Rules of the American Arbitration Association ("AAA") as herein provided. (a) The Arbitration Tribunal shall consist of three arbitrators. Each party shall nominate in the request for arbitration and the answer thereto one arbitrator and the two arbitrators so named will then jointly appoint the third arbitrator as chairman of the Arbitration Tribunal. If one party fails to nominate its arbitrator or, if the parties' arbitrators cannot agree on the person to be named as chairman within sixty (60) days, the necessary appointments shall be made under the rules of the AAA. (b) The place of arbitration shall be in Wilmington, Delaware and the arbitration proceedings shall be held in English. The procedural law of the place of arbitration shall apply where the AAA Rules are silent. (c) The award of the Arbitration Tribunal shall be final and judgment upon such an award may be entered in any competent court or application may be made to any competent court for judicial acceptance of such an award and order of enforcement. 16. SEPARABILITY 16.1. In the event any portion of this Agreement shall be held illegal, void or ineffective, the remaining portions hereof shall remain in full force and effect. 16.2.

In the event that the terms and conditions of this Agreement are materially altered as a result of Paragraphs 16.1 or 16.2, the parties will, in good faith, renegotiate the terms and conditions of this Agreement to resolve any inequities. 17.
