Wyeth-Ayerst shall have the right to sublicense all or any part of the rights granted to it under Section 3.1 to its Affiliates or Third Parties. Wyeth-Ayerst shall notify GalaGen of its intent to grant a sublicense to a Third Party prior to granting such sublicense under this Section 3.2, but Wyeth-Ayerst shall not be required to obtain GalaGen's consent to grant any such sublicense except in the case where Wyeth-Ayerst is sublicensing, to a Third Party, the right to develop and commercialize an Other Product included in the list of Preferential Other Products established by the JDC in accordance with Section 3.3.1 hereof, in which event, Wyeth-Ayerst may grant such sublicense to such Third Party only after obtaining GalaGen's prior written consent, which consent shall not be unreasonably withheld.

Each such notice shall include a proposed development plan for each Other Product included on such list. Within [**CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] after receiving the first such list the JDC shall meet to consider the list and proposed development plan(s) provided by GalaGen and any concerns that Wyeth-Ayerst has with the inclusion of any particular Other Product(s) on such list, and based on such considerations, the JDC shall establish a list of Other Products for which Wyeth-Ayerst must seek GalaGen's consent, in accordance with Section 3.2 hereof, prior to granting to one or more Third Parties a sublicense(s) to develop and commercialize such Other Products (the "Preferential Other Products"). Once each year the JDC shall meet [**CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] (i) to review the then current list of Preferential Other Products and GalaGen's progress in developing such Other Product in accordance with the development plan accepted by the JDC for such Other Product, and (ii) to consider the list of any Other Products provided by GalaGen and any concerns that Wyeth-Ayerst has with the inclusion of any particular Other Product(s) on the list of Preferential Other Products.

In the event GalaGen desires to develop and commercialize an Other Product (whether or not such Other Product is a Preferential Other Product), either itself or in collaboration with a Third Party, GalaGen may, by written notice to Wyeth-Ayerst, request that Wyeth-Ayerst grant to GalaGen a sublicense of the rights granted to Wyeth-Ayerst under Section 3.1.2 hereof solely for the development and commercialization of such Other Product. After the receipt of such 14 notice, Wyeth-Ayerst may elect whether or not to grant such sublicense and will not unreasonably refuse to grant such a sublicense to GalaGen, PROVIDED, HOWEVER, that in no event will Wyeth-Ayerst be required to grant a sublicense to GalaGen for the development and/or commercialization of such an Other Product if (i) Wyeth-Ayerst has initiated the development and/or commercialization of the same or a similar Other Product; (ii) Wyeth-Ayerst has advised the JDC pursuant to Section 2.4.5 hereof, that it intends to initiate the development of the same or a similar Other Product; (iii) Wyeth-Ayerst has, in accordance with Section 3.2 hereof, granted to a Third Party the right to develop and/or commercialize the same or a similar Other Product; (iv) Wyeth-Ayerst reasonably believes that the development and/or commercialization of such an Other Product would adversely affect the commercial potential of any Pediatric Formula Product that Wyeth-Ayerst has developed, is developing, plans to develop, is commercializing or plans to commercialize; (v) Wyeth-Ayerst is able to reasonably demonstrate that the development and/or commercialization of such an Other Product would have a material adverse effect on the commercial potential of any Other Product that Wyeth-Ayerst has developed, is developing or is commercializing; (vi) Wyeth-Ayerst is able to reasonably demonstrate that the development and/or commercialization of such an Other Product would have a material adverse effect on the commercial potential of any Other Product which Wyeth-Ayerst has advised the JDC, pursuant to Section 2.4.5 hereof, that it intends to initiate the development of; (vii) Wyeth-Ayerst is able to reasonably demonstrate that the development and/or commercialization of such an Other Product would have a material adverse 15 effect on the commercial potential of any product that is being developed or commercialized by Wyeth-Ayerst in one of Wyeth-Ayerst's core business areas; or (viii) [**CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***]. Wyeth-Ayerst will notify GalaGen of such election within [**CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] of receiving such notice from GalaGen. In the event that Wyeth-Ayerst elects to grant such a sublicense to GalaGen the Parties shall use their respective Commercially Reasonable Efforts to negotiate, in good faith, a definitive sublicense agreement containing terms and conditions (including, without limitation, whether such sublicense will be exclusive even as to Wyeth-Ayerst or exclusive except as to Wyeth-Ayerst) mutually acceptable to the Parties, PROVIDED, HOWEVER, that such sublicense, INTER ALIA, shall provide that (i) GalaGen shall pay to Wyeth-Ayerst [**CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] and (ii) Wyeth-Ayerst will be granted a right of first refusal to obtain the right to commercialize such Other Product(s) in the event GalaGen elects to license or otherwise transfer such responsibility to a Third Party, PROVIDED, HOWEVER, that Wyeth-Ayerst shall be required to waive its right to exercise such right of first refusal if (x) GalaGen, in its written notice requesting such sublicense, identifies a Third Party to whom GalaGen intends to further sublicense the right to commercialize such Other Product and (y) GalaGen, in fact, grants such a further sublicense to such Third Party within [**CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] after Wyeth-Ayerst grants to 16 GalaGen a sublicense to develop and/or commercialize such Other Product. The mechanism and timing for exercising such right of first refusal shall be mutually agreed upon by the Parties and shall be set forth in the definitive sublicense agreement, provided, however, that such sublicense agreement shall provide that Wyeth-Ayerst's acquisition of rights under such right of first refusal shall be substantially equivalent to the terms and conditions that GalaGen had negotiated, in good faith, with a Third Party. For purposes of this Section 3.3, a material adverse effect on a product shall include, without limitation, a forecasted decline of [**CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] in unit sales or revenues from the sale of such product. 3.3.3 FAILURE TO CONCLUDE NEGOTIATION OF SUBLICENSE.

In the event that Wyeth-Ayerst elects, for the reasons set forth in Section 3.3.2(ii) and/or Section 3.3.2(vi) above, not to grant to GalaGen a sublicense to develop and/or commercialize an Other Product and within [**CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] making such election Wyeth-Ayerst fails to either initiate the development of such Other Product or sublicense to a Third Party the right to develop and/or commercialize such Other Product, GalaGen, within [**CONFIDENTIAL TREATMENT REQUESTED; PORTION 17 OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] after the expiration of such [**CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] period, may, by written notice to Wyeth-Ayerst, request that such sublicense be granted and, in such event, Wyeth-Ayerst shall thereafter grant to GalaGen a sublicense to develop and commercialize such Other Product subject to the negotiation of a definitive sublicense agreement with GalaGen as provided in Section 3.3.2 hereof. 3.4 [***CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] 4.

The location and size of the GalaGen Trademark on such label or package shall be determined by Wyeth-Ayerst. Wyeth-Ayerst shall not and shall not authorize any of its Affiliates or sublicensees to (i) use the GalaGen Trademarks on any product other than Products or (ii) use any trademark that is confusingly similar to the GalaGen Trademarks, in either case without the prior written consent of GalaGen.

All Inventions made jointly by employees or agents of GalaGen and employees or agents of Wyeth-Ayerst and all patent applications and patents claiming such Inventions shall be owned jointly by GalaGen and Wyeth-Ayerst. All determinations of inventorship under this Section 8.1.1 shall be in accordance with United States law. 8.1.2 PATENT PROCUREMENT. Wyeth-Ayerst and GalaGen shall each disclose to the other and discuss any Inventions and the desirability of filing a United States patent application covering the Invention, as well as any foreign counterpart patent applications. The Party owning the Invention shall make the final decision with respect to any such filings and shall have the right to select patent counsel and to take such other actions as are reasonably appropriate to prepare, file, prosecute and maintain patent protection with respect to its Inventions arising under this Section 8.1. With respect to jointly owned Inventions, the Parties shall meet to determine in what countries, if any, patent applications claiming such joint Inventions should be filed. In the event that either Party does not wish to share in the expenses of both filing and prosecuting patent applications claiming such joint Inventions in any country of the Territory, such Party shall promptly assign or cause to be assigned to the other Party all of its right, title and interest in and to such joint Invention and thereafter such joint Invention shall be treated as an Invention solely owned by such other Party for all purposes of this Agreement. In the event both Parties desire to share in the expenses of applying for, obtaining and maintaining patents claiming such a joint Invention in one or more countries of the 24 Territory Wyeth-Ayerst shall file and prosecute any patent applications thereon in such countries and the out-of-pocket expenses incurred by Wyeth-Ayerst in preparing, filing, and prosecuting such joint patent applications and in maintaining any patents issued therefrom shall be shared equally by the Parties.

(a) If either Party should become aware of any infringement or 25 threatened infringement or misappropriation, as the case may be, in any country of the Territory, of any Intellectual Property Rights of the other Party, it shall promptly notify such other Party in writing. As soon as practicable the Parties shall confer on the particulars of such infringement or misappropriation and the possible courses of action to be taken. The Party holding the affected Intellectual Property Rights shall have the right, but not the obligation, to institute, prosecute and control any legal proceedings in its own name by its own counsel and at its own expense, subject to Section 8.5.1(d), to prevent or restrain such infringement, and the other Party shall have the right, at its own expense, to be represented in such action by its own counsel. If one Party brings any such action or proceeding, the other Party hereby consents to being joined as a party plaintiff where necessary and, in case of joining, such other Party agrees to give the first Party reasonable assistance and authority to file and to prosecute such suit, at the expense of the Party bringing such suit. (b) Notwithstanding the foregoing, the Parties shall jointly determine which Party shall have the primary right and responsibility (but not the obligation) to institute, prosecute, and control any action or proceeding with respect to infringement or misappropriation of jointly owned Intellectual Property Rights and the other Party shall have the right, at its expense, to be represented by its counsel. Each Party hereby consents to the filing of any such action by the other Party with respect to any jointly owned Patent Rights in accordance with this Section 8.5.1(b). (c) If one Party alone prosecutes an infringement or misappropriation of Intellectual Property Rights, after payment of its legal costs and expenses, any damages and costs recovered in any proceedings or by way of settlement under Sections 8.5.1(a) and 8.5.1(b) above or Section 8.5.2 shall belong to the Party bringing such action, subject to payment therefrom to the other Party of a reasonable sum to compensate the latter for loss of profits, as applicable. (d) If both Parties participate in prosecuting an infringement or misappropriation of Intellectual Property Rights, any damages and costs recovered in any proceedings or by way 26 of settlement under this Section 8.5.1 shall be shared by the Parties as follows: [**CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] 8.5.2 OTHER PARTY'S RIGHT TO PROSECUTE INFRINGEMENT. If the Party having the primary right to institute, prosecute, and control such infringement or misappropriation action under Section 8.5.1 fails to do so within a period of [**CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] after receiving notice of the infringement, or if that Party, after initiating an action, determines to discontinue such action, the other Party shall have the right, but not the obligation, to bring and control or take over any such action by counsel of its own choice, and its own expense, subject to Section 8.5.1(c) unless prevented from doing so by the laws of the country where the infringement or misappropriation occurred or is threatened. 8.5.3 SETTLEMENTS. In connection with any proposed settlement in respect of any infringement or threatened infringement of any Intellectual Property Rights, the Party intending to settle shall notify and consult with the other Party as to the terms of settlement, whose written consent shall be required prior to any such settlement, such consent not to be unreasonably withheld. 8.5.4 COOPERATION. In connection with any action taken by either Party against a Third Party to protect or enforce any Intellectual Property Rights, the other Party shall, if requested, consult with the Party taking such action, and make available as witnesses its employees or as evidence any materials, and/or data as are reasonably necessary for the furtherance of such action. The expenses in connection with the providing of witnesses and/or the making available of any materials and/or data shall be borne by the Party incurring them, and reimbursed pursuant to Section 8.5.1(d). 8.6 INFRINGEMENT OF THIRD PARTY PATENT RIGHTS. 8.6.1 INFRINGEMENT OF THIRD PARTY PATENTS. If Wyeth-Ayerst should be of the opinion that it cannot make, import, use, market and/or sell a Product in any country of the Territory under its own Intellectual Property Rights or those licensed to it by GalaGen under this 27 Agreement without infringing a Third Party's patent, it shall notify GalaGen. Both Parties then shall seek an opinion of patent counsel acceptable to both Parties. If such patent counsel concurs with Wyeth-Ayerst's opinion, they shall, at Wyeth-Ayerst's sole option, jointly or independently endeavor to secure a license from the Third Party on terms that are reasonably acceptable to both Parties. 8.6.2 OPINION OF COUNSEL. If, in the opinion of patent counsel selected under Section 8.6.1, the Third Party patent, if litigated, would be found invalid or not infringed by the manufacture, use or sale of Product or if the Parties otherwise mutually agree to obtain a license to such Third Party patent, the Parties shall proceed in accordance with the terms of this Agreement, unless an action for infringement is brought against one or both Parties. 8.6.3 DEFENSE AGAINST CLAIM OF INFRINGEMENT. If either Party is sued for infringement of any Third Party patents arising out of the manufacture, use, sale or importation of a Product in any country of the Territory, the Parties shall promptly meet to discuss the course of action to be taken to resolve or defend any such infringement litigation. Each Party shall provide the other with such assistance as is reasonably necessary and shall cooperate in the defense of any such action. If the allegation of infringement is due to or based on the use of [**CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] in a Product then, the cost/expense of defending such action incurred by Wyeth-Ayerst and any damages and/or other compensation imposed on Wyeth-Ayerst, by settlement or otherwise, in such country shall be shared equally by the Parties. GalaGen shall pay its share of such amounts pursuant to invoices submitted periodically by Wyeth-Ayerst which invoices shall be due and payable within thirty (30) days of GalaGen's receipt thereof. In the event that Wyeth-Ayerst has not made all payments due to GalaGen under this Agreement, Wyeth-Ayerst may deduct amounts due to Wyeth-Ayerst from GalaGen under this Section 8.6.3 from any amounts otherwise due GalaGen under this Agreement. 9. TERM AND TERMINATION. 9.1 TERM. This Agreement shall be effective as of the Effective Date and unless terminated earlier by mutual written agreement of the Parties or pursuant to Sections 9.2 or 9.3 below, the Term of this Agreement shall 28 continue in effect until the later of (i) expiration of the last to expire GalaGen Patent Right incorporating a Valid Claim which, but for the license granted under Section 3.1.1 hereof, would be infringed by the manufacture, use or sale of a Product by Wyeth-Ayerst hereunder or (ii) ten (10) years after the First Commercial Sale of a Product.

Additionally, the Parties will negotiate, in good faith, the grant by Wyeth-Ayerst of a license to GalaGen, on appropriate commercial terms, of any of Wyeth-Ayerst's Patent Rights or Know-How solely as such Patent Rights or Know-How relate to GalaGen's rights to manufacture and sell the [**CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] for use in Products. (c) In the event Wyeth-Ayerst terminates this Agreement under Section 9.2.1(b) or this Agreement is otherwise terminated under Section 9.2.1(b), the Parties agree that Wyeth-Ayerst, as a licensee of rights to intellectual property under this Agreement, shall retain and may fully exercise all of its rights and elections under Title 11 (as such term is defined in Section 9.6.1 hereof), including as set forth in Section 9.6 hereof. 9.3 UNILATERAL TERMINATION BY WYETH-AYERST. Wyeth-Ayerst shall have the right to unilaterally terminate this Agreement, on a country by country and 30 Product by Product basis, upon [**CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] written notice to GalaGen. In the event of such termination by Wyeth-Ayerst, all Wyeth-Ayerst's rights to use the [**CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] in such Products in such country shall revert to GalaGen. If Wyeth-Ayerst terminates this Agreement with respect to Pediatric Formula Products, Wyeth-Ayerst shall not be obligated to make any other payments under Section 5.1 of this Agreement for events which occur after the effective date of such termination and, in such event payments made by Wyeth-Ayerst to GalaGen under Article 5 hereof prior to such date shall be non-refundable. 9.4 GENERAL CONDITIONS OF EXPIRATION AND TERMINATION. 9.4.1 EFFECT ON SUBLICENSEES.

Upon early termination of this Agreement, for any reason, with respect to a particular Product in a given country or countries if any permitted sublicensee of such Product in such country(ies) is not then in default under its sublicense agreement with Wyeth-Ayerst, then such sublicensee shall automatically have a license under this Agreement as a direct licensee of GalaGen with respect to such Product in such country(ies), on economic terms as are set forth herein with respect to Wyeth-Ayerst and otherwise with the same rights and obligations as Wyeth-Ayerst under this Agreement. 9.4.2 EFFECT ON RIGHTS TO OTHER PRODUCTS.

Nothing herein shall exclude or limit any remedies or entitlements whatsoever which the law confers to either Party in the event of a breach of contractual obligations by the other Party. 9.6 INSOLVENCY. 9.6.1 EFFECT ON LICENSES.

Whenever GalaGen or any of its successors or assigns provides to Wyeth-Ayerst any of the intellectual property licensed hereunder (or any embodiment thereof) pursuant to this Section 9.6, Wyeth-Ayerst shall have the right to perform the obligations of GalaGen hereunder with respect to such intellectual property, but neither such provision nor such performance by Wyeth-Ayerst shall release GalaGen from any such obligation or liability for failing to perform it. 9.6.3 WYETH-AYERST'S RIGHTS. All rights, powers and remedies of Wyeth-Ayerst provided herein are in addition to and not in substitution for any and all other rights, powers and remedies now or hereafter existing at law or in equity (including, without limitation, Title 11) in the event of the commencement of a Title 11 case by or against GalaGen. Wyeth-Ayerst, in addition to the rights, power and remedies expressly provided herein, shall be entitled to exercise all other such rights and powers and resort to all other such remedies as may now or hereafter exist at law or in equity (including, without limitation, Title 11) in such event. The Parties agree that they intend the foregoing Wyeth-Ayerst rights to extend to the maximum extent permitted by law, including, without limitation, for purposes of Title 11: (i) the right of access to any intellectual property (including all embodiments thereof) of GalaGen, or any Third Party with whom GalaGen contracts to perform an obligation of GalaGen under this Agreement, and, in the case of the Third Party, which is necessary for the development, 33 registration, manufacture and marketing of [**CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] and/or Products; and (ii) the right to contract directly with any Third Party described in (i) to complete the contracted work. 10. INDEMNIFICATION AND INSURANCE. 10.1 INDEMNIFICATION BY WYETH-AYERST. Wyeth-Ayerst shall indemnify, defend and hold harmless GalaGen and its Affiliates, and each of its and their respective employees, officers, directors and agents (each, a "GalaGen Indemnified Party") from and against any and all liability, loss, damage, cost, and expense (including reasonable attorneys' fees) (collectively, a "Liability") which the GalaGen Indemnified Party may incur, suffer or be required to pay resulting from or arising in connection with (i) the breach by Wyeth-Ayerst of any representation or warranty contained in this Agreement; (ii) the manufacture, promotion, distribution, use, testing, marketing, sale or other disposition of Products by Wyeth-Ayerst, its Affiliates or sublicensees; or (iii) the successful enforcement by a GalaGen Indemnified Party of its rights under this Section 10.1. Notwithstanding the foregoing, Wyeth-Ayerst shall have no obligation under this Agreement to indemnify, defend or hold harmless any GalaGen Indemnified Party with respect to claims, demands, costs or judgments which result from either (x) the failure of [**CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] supplied by GalaGen or its Affiliates or subcontractors to comply with the specifications as set forth in the Manufacturing and Supply Agreement or the applicable Regulatory Approvals or (y) the willful misconduct or negligent acts or omissions of GalaGen, its Affiliates, or any of their respective employees, officers, directors or agents. 10.2 INDEMNIFICATION BY GALAGEN. GalaGen shall indemnify, defend and hold harmless Wyeth-Ayerst and its Affiliates, and each of its and their respective employees, officers, directors and agents (each, a "Wyeth-Ayerst Indemnified Party") from and against any Liability which the Wyeth-Ayerst Indemnified Party may incur, suffer or be required to pay resulting from or arising in connection with (i) the breach by GalaGen of any representation or warranty contained in this Agreement; (ii) the 34 discovery, development, manufacture, promotion, sale or use of [**CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] or Other Products by GalaGen, its Affiliates or their subcontractors or permitted sublicensees; or (iii) the successful enforcement by a Wyeth-Ayerst Indemnified Party of its rights under this Section 10.2. Notwithstanding the foregoing, GalaGen shall have no obligation under this Agreement to indemnify, defend, or hold harmless any Wyeth-Ayerst Indemnified Party with respect to claims, demands, costs or judgments which result from willful misconduct or negligent acts or omissions of Wyeth-Ayerst, its Affiliates, or any of their respective employees, officers, directors or agents. 10.3 CONDITIONS TO INDEMNIFICATION. The obligations of the indemnifying Party under Sections 10.1 and 10.2 are conditioned upon the delivery of written notice to the indemnifying Party of any potential Liability promptly after the indemnified Party becomes aware of such potential Liability, PROVIDED, HOWEVER, that the failure to give such notice promptly shall not impair a Party's rights to indemnification under this Article 10 unless the delay in providing such notice has a material adverse effect on the ability of the indemnifying Party to defend against such Liability. The indemnifying Party shall have the right to assume the defense of any suit or claim related to the Liability if it has assumed responsibility for the suit or claim in writing; however, if in the reasonable judgment of the indemnified Party, such suit or claim involves an issue or matter which could have a materially adverse effect on the business operations or assets of the indemnified Party, the indemnified Party may waive its rights to indemnity under this Agreement and control the defense or settlement thereof, but in no event shall any such waiver be construed as a waiver of any indemnification rights such Party may have at law or in equity. If the indemnifying Party defends the suit or claim, the indemnified Party may participate in (but not control) the defense thereof at its sole cost and expense. 10.4 SETTLEMENTS. Neither Party may settle a claim or action related to a Liability without the consent of the other Party, if such settlement would impose any monetary obligation on the other Party or require the other Party to submit to an injunction or otherwise limit the other Party's rights under this Agreement. Any payment made by a Party to settle any such claim or action shall be at its own cost and expense except in the event that such payment was made with the prior written consent of the indemnifying Party, in which case such payment will be subject to the indemnification obligations of the Parties as set forth in this Article 10. 35 10.5 INSURANCE. Each Party further agrees to use reasonable commercial efforts to obtain and maintain, during the term of this Agreement, Comprehensive General Liability Insurance, including Products Liability Insurance, with reputable and financially secure insurance carriers to cover its indemnification obligations under Sections 10.1 or 10.2, as applicable, or, in the case of Wyeth-Ayerst, self-insurance, in each case with limits of not less than [**CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***]. 11.
