If by law, regulation, or fiscal policy of a particular country, conversion into United States dollars or transfer of funds of a convertible currency to the United States is restricted or forbidden, the party owing such payment shall give the party to which such payment is owed prompt written notice and shall make such payment due under this Article 11 through such means or methods as are lawful in such country as the party to which such payment is owed may reasonably designate. Failing the designation by the party to which such payment is owed of such lawful means or methods within [**]after such written notice is given to such party, the party owing such payment shall deposit such royalty payment in local currency to the credit of the party to which such payment is owed in a recognized banking institution designated by such party, or if none is designated by such party within the [**] period described above, in a recognized banking institution selected by the party owing such payment and identified in a written notice to other party, and such deposit shall fulfill all obligations of the party owing such payment to the other party with respect to such payment. 11.9 Interest on Late Payments. A party to which payment is owed under this Agreement shall have the right to seek to collect interest on any payments that are not paid on or before [**] after the date such payments are due under this Agreement at a rate equal to [**], calculated on the total number of days payment is delinquent. The party to which interest is owed shall send a written notice to the delinquent party notifying it of any such delinquency; provided, that such party shall not be required to send more than two (2) such notices in any Contract Year and; provided, further, that the date of delivery of such notice shall not affect the calculation of the amount of interest owed hereunder. 11.10 Manner of Payment.

If such other party elects to continue Patent Prosecution, it will not be liable to the other party in any way with respect to its handling of, or the results obtained from, such Patent Prosecution. The other party will provide the party taking over Patent Prosecution with such assistance and execute such documents as are necessary to continue or permit such Patent Prosecution. 12.2.3 Right of Review. The prosecuting party under Sections 12.2.1 or 12.2.2 shall provide the other party with a reasonable opportunity to review and provide substantive input to material decisions relating to Patent Prosecution. The prosecuting party shall furnish to the other party copies of any substantive actions prepared for the U.S. Patent and Trademark Office or its foreign counterparts that may materially affect the Program Patent Rights being prosecuted or maintained reasonably in advance of the filing of such action in order to provide such party with a meaningful opportunity to comment thereon. Such action filed by the prosecuting party shall reflect any comments received from the other party that are received in a reasonably timely manner and are reasonably directed to maximizing the coverage of the claims of such Program Patent Rights being prosecuted or maintained. 12.2.4 Patent Prosecution Costs. All Patent Prosecution expenses, including attorneys' fees, incurred in the performance of Patent Prosecution under Section 12.2.1 or 12.2.2 shall be shared by the parties in accordance with the Cost Sharing Ratio. 12.2.5 Cooperation. Each party hereby agrees: (a) to take all reasonable additional actions and execute such agreements, instruments and documents as may be reasonably required to perfect the other's 46 ownership interest in accordance with the intent of this Agreement, including, without limitation, requiring inventors to make appropriate patent assignments; (b) to make its employees, Affiliates, agents, independent contractors and consultants reasonably available to the other party (or to the other party's authorized attorneys, agents or representatives), to the extent reasonably necessary to enable the prosecuting party to undertake Patent Prosecution; (c) to provide the other party with copies of all material correspondence with the U.S. Patent and Trademark Office or its foreign counterparts; (d) to cooperate, if necessary and appropriate, with the other party in gaining patent term extensions wherever applicable to Program Patent Rights for Program Inventions; and (e) to endeavor in good faith to coordinate its efforts with the other party to minimize or avoid interference with the Patent Prosecution of the other party's patent applications related to inventions within the Program Technology and Program Intellectual Property. 12.3 Patent Term Extension. Each party shall cooperate with the other in obtaining patent term extension or supplemental protection certificates or their equivalents in any country with respect to the Program Patent Rights. 12.4 Enforcement of the Program Patent Rights. 12.4.1 Notices of Third Party Infringement.

Each party shall provide to the other party copies of any allegations of alleged patent invalidity, unenforceability or non-infringement of a patent or patents with respect to Program Technology, Program Materials or Collaboration Products pursuant to a Paragraph IV Patent Certification by a Third Party filing an Abbreviated New Drug Application (i.e., an action under the Hatch-Waxman Act). Such copies shall be provided promptly after receipt of such certification. 12.4.3 Other Notifications. Each party shall provide to the other party copies of any notices it receives from Third Parties regarding any patent nullity actions, any declaratory judgment actions, any alleged infringement of Program Patent Rights or any alleged misappropriation of intellectual property with respect to Program Technology, Program Materials or Collaboration Products.

Each party will bear its own costs, including attorneys' fees, relating to such legal proceedings; provided that Lexicon shall bear Organon's out-of- 47 pocket expenses, including attorneys' fees, incurred in complying with requests for cooperation made by Lexicon. Any recovery in connection with such suit or proceeding will first be applied to reimburse the parties for their out-of-pocket expenses, including attorneys' fees. All recoveries resulting from such legal proceedings that are in excess of the parties' costs of bringing or participating in such action, including attorneys' fees, shall be allocated in accordance with the Cost Sharing Ratio. 12.4.4.2 If Lexicon elects not to institute and direct legal proceedings against any Third Party believed to be infringing the Program Patent Rights of either party as described in Section 12.4.4.1, Organon shall have the right, but not the obligation, to institute and direct such legal proceedings. Each party will bear its own costs, including attorneys' fees, relating to such legal proceedings; provided that Organon shall bear Lexicon's out-of-pocket expenses, including attorneys' fees, incurred in complying with requests for cooperation made by Organon. Any recovery in connection with such suit or proceeding will first be applied to reimburse the parties for their out-of-pocket expenses, including attorneys' fees. All recoveries resulting from such legal proceedings that are in excess of the parties' costs of bringing or participating in such action, including attorneys' fees, shall be allocated in accordance with the Cost Sharing Ratio. 12.4.4.3 In the event that a party takes action under this Section 12.4.4, the other party shall cooperate to the extent reasonably necessary at the sole expense of the party taking such action. Upon the reasonable request of the party taking such action, the other party shall join the suit and shall be represented in any such legal proceedings using counsel of its own choice. Neither party shall settle or otherwise agree to the final disposition of any claim or proceeding relating to Program Patent Rights Controlled in whole or in part by the other party or licensed under this Agreement to the other party without the prior written consent of such other party, which consent shall not be unreasonably withheld. 12.4.5 Non-Product-Related Infringement. Each party shall have the sole right, but not the obligation, to institute and direct legal proceedings against any Third Party believed to be infringing the Program Patent Rights solely owned by such party other than infringement relating to a Collaboration Product. All costs, including attorneys' fees, relating to such legal proceedings shall be borne by the party instituting such legal proceedings, and all recoveries resulting from such legal proceedings shall be retained by such party. The parties shall consult with each other regarding the institution, prosecution and control of any action or proceeding with respect to infringement of any of the Program Patent Rights jointly owned by the parties other than infringement relating to a Collaboration Product. 12.5 Notices of Other Proceedings. 12.5.1 Each party shall notify the other in writing of any allegations it receives from a Third Party that the manufacture, use, sale, offer for sale or import of Program Technology, Program Materials or any Collaboration Product infringes the intellectual property rights of such Third Party. Such notice shall be provided promptly following receipt of such allegations. 12.5.2 In the event that a party receives notice that it or any of its Affiliates have been individually named as a defendant in a legal proceeding by a Third Party alleging infringement of a Third Party patent or other intellectual property right as a result of the manufacture, use, sale, offer for sale or import of Program Technology, Program Materials or a Collaboration Product, 48 such party shall immediately notify the other party in writing after the receipt of such notice. Such written notice shall include a copy of any summons or complaint (or the equivalent thereof) received regarding the foregoing. ARTICLE 13. CONFIDENTIALITY 13.1 Nondisclosure Obligations. 13.1.1 General. Except as otherwise provided in this Article 13, during the term of this Agreement and for a period of five (5) years thereafter, each Receiving Party shall maintain the Confidential Information of each Disclosing Party in confidence and use it only for purposes specifically authorized under this Agreement. 13.1.2 Limitations. To the extent it is reasonably necessary or appropriate to fulfill its obligations or exercise its rights under this Agreement and subject to advance written notification to the Disclosing Party: (a) a party may disclose to Third Parties Confidential Information it is otherwise obligated not to disclose under this Section 13.1, to its Affiliates, (sub)licensees, consultants, outside contractors and clinical investigators, on a strict need-to-know basis for the purposes contemplated by this Agreement and on condition that such entities or persons agree to keep the Confidential Information confidential for the same time periods and to the same extent as such party is required to keep the Confidential Information confidential hereunder; and (b) a party or its (sub)licensees may disclose, using appropriate measures to preserve confidentiality, such Confidential Information to government or other regulatory authorities to the extent that such disclosure is reasonably necessary to obtain authorizations to conduct clinical trials of, and to commercially market, Collaboration Products pursuant to this Agreement. Furthermore, a Receiving Party may request permission from the Disclosing Party to disclose such Confidential Information to the extent that such disclosure is reasonably necessary to [**]. 13.1.3 Required Disclosure. A Receiving Party may disclose Confidential Information pursuant to interrogatories, requests for information or documents, subpoena, civil investigative demand issued by a court or governmental agency or as otherwise required by law; provided, however, that the Receiving Party shall notify the Disclosing Party promptly upon receipt thereof, giving [**] the Disclosing Party sufficient advance notice to permit it to oppose, limit or seek confidential treatment for such disclosure; and provided, further, that the Receiving Party shall furnish only that portion of the Confidential Information which it is advised by counsel is legally required whether or not a protective order or other similar order is obtained by the Disclosing Party. 13.2 Injunctive Relief. The parties hereto understand and agree that remedies at law may be inadequate to protect against any breach of any of the provisions of this Article 13 by either party or their employees, agents, officers or directors or any other person acting in concert with it or on its behalf. Accordingly, each party shall be entitled to the granting of injunctive relief by a court of competent jurisdiction against any action that constitutes any such breach of this Article 13. 13.3 Publication. Organon and Lexicon (each, a "Submitting Party") may each publish or present data and results relating to a Collaboration Product or Opt-out Product for which the Submitting Party holds a commercial license under Section 9.2 hereof, subject to the prior review of the proposed disclosure by the other party (each, a "Reviewing Party"), solely to determine (a) whether the proposed disclosure contains the Confidential Information of the Reviewing Party or (b) whether the information contained in the proposed disclosure should be the subject of a patent application to be filed by the Reviewing Party prior to such disclosure. Each Submitting Party shall provide the Reviewing Party with 49 the opportunity to review any proposed abstract, manuscript or presentation by delivering a copy thereof to the Reviewing Party no less than [**] before its intended submission for publication or presentation. The Reviewing Party shall have [**] from its receipt of any such abstract, manuscript or presentation in which to notify the Submitting Party in writing of any specific objections to the disclosure, based on either the need to seek patent protection or concern regarding the specific disclosure of the Confidential Information of the Reviewing Party. In the event the Reviewing Party objects to the disclosure, the Submitting Party agrees not to submit the publication or abstract or make the presentation containing the objected-to information until the Reviewing Party is given a reasonable additional period of time (not to exceed an additional [**]) to seek patent protection for any material in the disclosure which the Reviewing Party believes is patentable (subject, in all events, to Section 13.2) or, in the case of Confidential Information, to allow the Submitting Party to delete any Confidential Information of the Reviewing Party from the proposed disclosure. The Submitting Party agrees to delete from the proposed disclosure any Confidential Information of the Reviewing Party upon request. ARTICLE 14.

ARTICLE 15. INDEMNITY 15.1 Lexicon Indemnity Obligations. Lexicon agrees to defend, indemnify and hold Organon, its Affiliates and their respective employees and agents harmless from all claims, losses, damages or 51 expenses (including reasonable attorneys' fees and costs of litigation) arising as a result of: (a) actual or asserted violations of any applicable law or regulation by Lexicon, its (sub)licensees and their respective Affiliates by virtue of which any Lexicon Products manufactured, distributed or sold by Lexicon hereunder as Continuing Party shall be alleged or determined to be adulterated, misbranded, mislabeled or otherwise not in compliance with any applicable law or regulation; (b) claims for bodily injury, death or property damage attributable to the manufacture, distribution, sale or use of any Lexicon Products by Lexicon as Continuing Party, its (sub)licensees and their respective Affiliates; (c) a recall of a Lexicon Product manufactured, distributed or sold by Lexicon hereunder as the Continuing Party ordered by a governmental agency or required by a confirmed Lexicon Product failure as reasonably determined by the parties hereto; or (d) Lexicon's breach of any of its representations, warranties or covenants hereunder. 15.2 Organon Indemnity Obligations. Organon agrees to defend, indemnify and hold Lexicon, its Affiliates and their respective employees and agents harmless from all claims, losses, damages or expenses (including reasonable attorneys' fees and costs of litigation) arising as a result of: (a) actual or asserted violations of any applicable law or regulation by Organon, its (sub)licensees and their respective Affiliates by virtue of which any Organon Products manufactured, distributed or sold by Organon hereunder as the Continuing Party shall be alleged or determined to be adulterated, misbranded, mislabeled or otherwise not in compliance with any applicable law or regulation; (b) claims for bodily injury, death or property damage attributable to the manufacture, distribution, sale or use of any Organon Products by Organon as Continuing Party hereunder, its (sub)licensees and their respective Affiliates; (c) a recall of an Organon Product manufactured, distributed or sold by Organon hereunder as the Continuing Party ordered by a governmental agency or required by a confirmed Organon Product failure as reasonably determined by the parties hereto; or (d) Organon's breach of any of its representations, warranties or covenants hereunder. 15.3 Limitation on Indemnity Obligations. Neither party, its Affiliates or their respective employees and agents shall be entitled to the indemnities set forth in Sections 15.1 or 15.2, respectively, to the comparative extent the claim, loss, damage or expense for which indemnification is sought was caused by a grossly negligent, reckless or intentional act or omission by such party, its directors, officers, employees or authorized agents. 15.4 Procedure. If a party or any of its Affiliates or their respective employees or agents (collectively, the "Indemnitee") intends to claim indemnification under this Article 15, 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 shall assume the defense thereof with counsel selected by the Indemnitor and reasonably acceptable to the Indemnitee, provided, however, that an Indemnitee shall have the right to retain its own counsel, with the fees and expenses to be paid by the Indemnitee, 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 Indemnitor shall have the right to settle or compromise any claims for which it is providing indemnification under this Article 15, provided that the consent of the Indemnitee (which shall not be unreasonably withheld or delayed) shall be required in the event any such settlement or compromise would adversely affect the interests of the Indemnitee. The indemnity agreement in this Article 15 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. The failure to deliver notice to the Indemnitor within a reasonable time after the commencement of any such action, if prejudicial to the Indemnitor's ability to defend such action, shall relieve such Indemnitor of any liability to the Indemnitee under this Article 15, 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 Article 15. The Indemnitee under this Article 15, its employees and agents, shall 52 cooperate fully with the Indemnitor and its legal representatives in the investigation of any action, claim or liability covered by this indemnification. 15.5 Insurance. Each party shall maintain appropriate product liability insurance with respect to Development, Manufacture and commercialization of Collaboration Products by such party in such amount as such party customarily maintains with respect to sales of its other products. Each party shall maintain such insurance for so long as it continues to manufacture or sell Collaboration Products, and thereafter for so long as such party customarily maintains insurance with respect to sales of its other products. ARTICLE 16. EXPIRATION AND TERMINATION 16.1 Term of Agreement. The term of this Agreement shall commence on the Effective Date and shall continue until the later of (a) the expiration or termination of the last to expire of any Valid Claim included in the Program Patent Rights and (b) the cessation of Development or commercialization activities with respect to all Collaboration Products generated pursuant to the terms hereof. 16.2 Events of Default. An Event of Default by either party shall have occurred upon (a) the occurrence of a material breach of this Agreement if such party fails to remedy such breach within [**] after written notice thereof by the non-breaching party ([**] in the event of a party's failure to make a payment required hereunder) or, if remediation of such breach in [**] is not practicable, if such party fails to commence and diligently pursue such remediation during such [**] period, or (b) the commencement of any proceeding in or for bankruptcy, insolvency, dissolution or winding up by or against such party that is not dismissed or otherwise disposed of within [**] thereafter. 16.3 Effect of an Event of Default. In the event of an Event of Default, the non-defaulting party shall have the right, at its option exercisable in its sole discretion, in addition to any other rights or remedies available to it at law or in equity and subject to the limitations set forth in Sections 3.8.2, 14.4 and 17.7 hereof, to terminate this Agreement upon [**] notice thereof to the other party, in which case (a) the licenses granted to the defaulting party pursuant to Article 9 shall terminate and (b) the defaulting party shall return to the non-defaulting party or, upon the non-defaulting party's written instruction, destroy all information, materials or documentation provided by the non-defaulting party pursuant to this Agreement; provided that such termination shall apply to the rights and licenses granted to the defaulting party under Sections 9.1 and 9.2 with respect to a Collaboration Product or Opt-out Product only in the event, and to the extent, that such Event of Default relates to such specific Collaboration Product or Opt-out Product, in which case the defaulting party shall be deemed to have Opted Out of any such Collaboration Product with the same effect (subject to any other rights or remedies available to the non-defaulting party at law or in equity) as if such breaching party had Opted Out under Section 10.1.1.1. For the avoidance of doubt, the termination rights of the non-defaulting party under this Section 16.3 shall be in addition to any other rights or remedies available to it at law or in equity. The rights and licenses granted to the defaulting party under Sections 9.1 and 9.2 with respect to any Collaboration Product or Opt-out Product with respect to which no Event of Default has occurred shall, subject to such party's applicable obligations under this Agreement with respect thereto, continue. In the event that this Agreement is terminated pursuant to this Section 16.3, the defaulting party's obligations under the exclusivity provisions set forth in Section 2.4 shall survive for five (5) years following such termination. 16.4 Effect of Expiration or Termination of Agreement. The expiration or termination of this Agreement shall not relieve the parties of any obligation accruing prior to such expiration or termination. The provisions of Articles 12, 13 and 15, Sections 8.5, 8.6 and 17.2 and Sections 17.4 through 17.7 hereof shall survive the expiration or termination of this Agreement. The rights and licenses granted to the non-defaulting party under Sections 9.1 and 9.2 hereof shall survive any termination of this Agreement by 53 such non-defaulting party pursuant to Section 16.3. The provisions of Sections 11.2 through 11.11 hereof shall survive any termination of this Agreement under which a party, its (sub)licensees or their respective Affiliates retains the right to sell Collaboration Products until such time as this Agreement would have expired with respect to any Collaboration Product, as the case may be, in any country pursuant to Section 16.1 hereof had this Agreement not been earlier terminated. ARTICLE 17. MISCELLANEOUS 17.1 Force Majeure. Neither party shall be held liable or responsible to the other party nor be deemed to have defaulted under or breached this Agreement for failure or delay in fulfilling or performing any obligation under this Agreement when such failure or delay is caused by or results from causes beyond the reasonable control of the affected party, including but not limited to fire, floods, embargoes, war, acts of war (whether war is declared or not), insurrections, riots, civil commotions, strikes, lockouts or other labor disturbances, acts of God or acts, omissions or delays in acting by any governmental authority; provided, however, that the party so affected shall use reasonable commercial efforts to avoid or remove such causes of nonperformance, and shall continue performance hereunder with reasonable dispatch whenever such causes are removed. Either party shall provide the other party with prompt written notice of any delay or failure to perform that occurs by reason of force majeure. The parties shall mutually seek a resolution of the delay or the failure to perform as noted above. 17.2 Assignment. This Agreement may not be assigned or otherwise transferred, in whole or in part, by either party without the consent of the other party; provided, however, that either Lexicon or Organon may, without such consent, assign its rights and obligations under this Agreement (i) to any Affiliate, or (ii) in connection with a merger, consolidation or sale of such portion of a party's assets that includes rights under this Agreement to an unrelated Third Party; provided, further, that such party's rights and obligations under this Agreement shall be assumed by its successor in interest in any such transaction and shall not be transferred separate from all or substantially all of its other business assets, including those business assets that are the subject of this Agreement. Any purported assignment in violation of the preceding sentence shall be void. Any permitted assignee shall assume all obligations of its assignor under this Agreement, unless the parties otherwise agree.

Such amounts shall be determined from the books and records of Lexicon, Organon and their respective Affiliates maintained in accordance with GAAP. In the event the Licensed Product is sold as part of a Combination Product (as defined below), the Net Sales of the Licensed Product attributable to the Combination Product will be determined by multiplying the Net Sales of the Combination Product by the fraction, A/A+B where A is the average sales price of the Licensed Product when sold separately in finished form and B is the average sales price of the other active compounds or ingredients in the Combination Product sold separately in finished form. In the event that the average sale price of the Licensed Product can be determined but the average sales price of the other active compounds or ingredients cannot be determined, the Net Sales of the Licensed Product attributable to the Combination Product will be determined by multiplying the Net Sales of the Combination Product by the fraction C/C+D where C is the selling party's average sales price of the Licensed Product and D is the difference between the average sales price of the Combination Product and the average sales price of the Licensed Product.

The Net Sales price for a Combination Product in a given country will be calculated once each Contract Year and such price will be used during all applicable revenue reporting periods for the entire Contract Year for such country, absent extraordinary conditions or events. When determining the average sales price of the Licensed Product or the other active compounds or ingredients in the Combination Product, the average sales price will be calculated using data arising from the twelve (12) months preceding the calculation of the Net Sales price for the Combination Product. As used above, the term "Combination Product" means the Licensed Product sold in conjunction with any other active component(s) (whether packaged together or in the same therapeutic formulation). If Lexicon, Organon or their Affiliates sells the Licensed Product to a customer which also purchases other products or services from such seller in a bundled, combination or capitated transaction (a "Bundled Transaction"), and such seller discounts the sales price of the Licensed Product to a greater degree than such seller generally discounts the price of its other products to such customer, then the aggregate amount received with respect to such Bundled Transaction shall be allocated to Net Sales pursuant to the formula set forth in Exhibit 1.40 hereto. For purposes of the foregoing, "discounting" includes establishing the list price at lower than the seller's normal pricing level. Free samples of Licensed Product and the disposition of Licensed Product for, or the use of Licensed Product in Post-approval Studies in which such Licensed Product is provided to patients without any payment shall not result in any Net Sales. 1.41 "Operating Profit/Loss" means (a) Net Sales of the Licensed Product in the Collaboration Field in the Co-Commercialization Territory during the relevant time period less (b) the Allowable Commercialization Costs incurred by Lexicon and Organon in respect of the Licensed Product during such time period.

The parties hereto understand and agree that remedies at law may be inadequate to protect against any breach of any of the provisions of this Article 7 by either party or their employees, agents, officers or directors or any other person acting in concert with it or on its behalf.

INDEMNITY 9.1 Lexicon Indemnity Obligations. Lexicon agrees to defend, indemnify and hold Organon, its Affiliates and their respective employees and agents harmless from all claims, losses, damages or expenses (including reasonable attorneys' fees and costs of litigation) arising as a result of Lexicon's breach of any of its representations, warranties or covenants hereunder. 9.2 Organon Indemnity Obligations. Organon agrees to defend, indemnify and hold Lexicon, its Affiliates and their respective employees and agents harmless from all claims, losses, damages or expenses (including reasonable attorneys' fees and costs of litigation) arising as a result of Organon's breach of any of its representations, warranties or covenants hereunder. 9.3 Limitation on Indemnity Obligations. Neither party, its Affiliates or their respective employees and agents shall be entitled to the indemnities set forth in Sections 9.1 or 9.2, respectively, to the comparative extent the claim, loss, damage or expense for which indemnification is sought was caused by a grossly negligent, reckless or intentional act or omission by such party, its directors, officers, employees or authorized agents. 9.4 Procedure. If a party or any of its Affiliates or their respective employees or agents (collectively, the "Indemnitee") intends to claim indemnification under this Article 9, 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 shall assume the defense thereof with counsel selected by the Indemnitor and reasonably acceptable to the Indemnitee, provided, however, that an Indemnitee shall have the right to retain its own counsel, with the fees and expenses to be paid by the Indemnitee, 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 Indemnitor shall have the right to settle or compromise any claims for which it is providing indemnification under this Article 15, provided that the consent of the Indemnitee (which shall not be unreasonably withheld or delayed) shall be required in the event any such settlement or compromise would adversely affect the interests of the Indemnitee. The indemnity agreement in this Article 9 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. The failure to deliver notice to the Indemnitor within a reasonable time after the commencement of any such action, if prejudicial to the Indemnitor's ability to defend such action, shall relieve such Indemnitor of any liability to the Indemnitee under this Article 9, 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 Article 9. The Indemnitee under this Article 9, its employees and agents, shall cooperate fully with the Indemnitor and its legal representatives in the investigation of any action, claim or liability covered by this indemnification. 9.5 Insurance. Each party shall maintain appropriate product liability insurance with respect to Commercialization of the Licensed Product by such party in such amount as such party customarily maintains with respect to sales of its other products.

An Event of Default by either party shall have occurred upon (a) the occurrence of a material breach of this Agreement if such party fails to remedy such breach within [**] after written notice thereof by the non-breaching party ([**] in the event of a party's failure to make a payment required hereunder) or, if remediation of such breach in [**] is not practicable, if such party fails to commence and diligently pursue such remediation during such [**] period, or (b) the commencement of any proceeding in or for bankruptcy, insolvency, dissolution or winding up by or against such party that is not dismissed or otherwise disposed of within [**] thereafter. 10.3 Effect of an Event of Default.

The expiration or termination of this Agreement shall not relieve the parties of any obligation accruing prior to such expiration or termination. The provisions of Articles 7 and 9 and Sections 11.2 and 11.4 through 11.7 hereof shall survive the expiration or termination of this Agreement. ARTICLE 11. MISCELLANEOUS 11.1 Force Majeure. Neither party shall be held liable or responsible to the other party nor be deemed to have defaulted under or breached this Agreement for failure or delay in fulfilling or performing any obligation under this Agreement when such failure or delay is caused by or results from causes beyond the reasonable control of the affected party, including but not limited to fire, floods, embargoes, war, acts of war (whether war is declared or not), insurrections, riots, civil commotions, strikes, lockouts or other labor disturbances, acts of God or acts, omissions or delays in acting by any governmental authority; provided, however, that the party so affected shall use reasonable commercial efforts to avoid or remove such causes of nonperformance, and shall continue performance hereunder with reasonable dispatch whenever such causes are removed. Either party shall provide the other party with prompt written notice of any delay or failure to perform that occurs by reason of force majeure. The parties shall mutually seek a resolution of the delay or the failure to perform as noted above. 11.2 Assignment. This Agreement may not be assigned or otherwise transferred, in whole or in part, by either party without the consent of the other party; provided, however, that either Lexicon or Organon may, without such consent, assign its rights and obligations under this Agreement (i) to any Affiliate, or (ii) in connection with a merger, consolidation or sale of such portion of a party's assets that includes rights under this Agreement to an unrelated Third Party; provided, further, that such party's rights and obligations under this Agreement shall be assumed by its successor in interest in any such transaction and shall not be transferred separate from all or substantially all of its other business assets, including those business assets that are the subject of this Agreement. Any purported assignment in violation of the preceding sentence shall be void. Any permitted assignee shall assume all obligations of its assignor under this Agreement, unless the parties otherwise agree. 21 11.3 Change in Control. 11.3.1 Notice of and Reasonable Assurances upon a Change in Control.

If the Acquiring Party fails to provide the assurances contemplated by Section 11.3.1 within the [**] period set forth therein, and does not cure such failure within [**] after notice from the other party, the Acquiring Party shall be deemed to have Opted Out of the Licensed Product, with the same effect as if the Acquiring Party had Opted Out under Section 10.1.1.1 of the Collaboration Agreement; provided that the Acquiring Party shall not [**] with respect to (a) [**] or (b) [**]. 11.3.3 Option to Negotiate for Rights to Collaboration Product. Without limiting the foregoing, if requested by the other party at any time within the [**] period following the Acquiring Party's notice under Section 11.3.1 of a Change in Control, the Acquiring Party and the other party shall enter into good faith negotiations, for a period of [**] following such request, for the other party to obtain from the Acquiring Party the exclusive rights to Commercialize the Licensed Product.
