7.8 Records; Audit.

7.8.1 Records Retention. Each Party, its Affiliates and Sublicensees will maintain complete and accurate books, records and accounts in sufficient detail to confirm the accuracy of any payments required hereunder (the “Payment Records”), which books, records and accounts will be retained by the applicable party until * * * after the end of the period to which such books, records and accounts pertain. Kos will ensure that each Sublicense Agreement provides for record retention and audit rights corresponding to this Section 7.8 and permitting Jerini to have such Sublicensee’s Payment Records audited in accordance with provisions corresponding to this Section 7.8.

7.8.2 Audit. Each Party will have the right to have an independent certified public accounting firm of internationally recognized standing to have access during normal business hours, and upon reasonable prior written notice, to such of the Payment Records of the audited party as may be reasonably necessary to verify the accuracy of information needed to calculate payments required hereunder for any * * * ending not more than * * * prior to the date of such request; provided, however, that a Party will not have the right to conduct more than * * * such audit in any * * * period. The accounting firm will disclose to the Parties (and, in the case of an audit initiated by Jerini, to Sanofi-Aventis) only whether the Net Sales reported by the audited Party are correct or incorrect and the specific details concerning any discrepancies. The auditing Party will bear all reasonable costs of such audit, unless the audit reveals a discrepancy in the audited Party’s favor of more than * * *, in which case the audited Party will bear the reasonable cost of the audit.

7.8.3 Payment of Additional Amounts. If, based on the results of any audit, additional payments are owed to either Party under this Agreement, then the other Party will make such additional payments promptly after the accounting firm’s written report is delivered to both Parties.

7.8.4 Termination of Rights. Except in the case of circumstances which would have prevented an error or anomaly from being disclosed during an audit performed under this Section 7.8, such as fraud, misrepresentation or other willful misconduct or gross negligence to provide accurate information, upon the expiration of * * * following the end of any calendar year, the calculation of royalties payable with respect to such year will be binding and conclusive upon each Party and the Party responsible for payment of royalties will be released from any liability or accountability with respect to royalties for such year.

7.8.5 Confidentiality. Each Party will treat all information subject to review under this Section 7.8 in accordance with the provisions of Section 12 and will cause its accounting firm to enter into a reasonably acceptable confidentiality agreement with the audited Party obligating such firm to maintain all such financial information in confidence pursuant to such confidentiality agreement.

7.9 Taxes.

7.9.1 Withholding Taxes. Payee will be responsible for any income or other taxes owed by Payee or required by applicable law to be withheld or deducted from any of the royalty and other payments made by or on behalf of Payor to Payee hereunder (“Withholding Taxes”), and Payor may deduct from any amounts that Payor is required to pay to Payee hereunder an amount equal to such Withholding Taxes as relate to such payments. Payee will provide Payor any information available to Payee that is necessary to determine the Withholding

Taxes. Payor will pay such Withholding Taxes to the proper taxing authority for Payee’s account and will send evidence of such payment to Payee within one month of such payment. The Parties will do all such lawful acts and things and sign all such lawful deeds and documents as either Party may reasonably request from the other Party to enable Payee and Payor or its Affiliates or Sublicensees to take advantage of any applicable legal provision or any double taxation treaties with the object of paying the sums due to Payee hereunder without withholding or deducting any Withholding Taxes. Without limiting the immediately preceding sentence, Kos agrees that, with respect to any royalty or other payment made by or on behalf of Kos to Jerini hereunder after Kos has received both a properly executed Form W-9 from Jerini and such other documents as Kos determines are of a sufficient basis upon which Kos may rely to establish that Kos does not know or have reason to know that it is, by reason of this Agreement, a financed entity in a conduit financing arrangement (as such terms are defined by section 1.881-3 of the Treasury Regulations), Kos will not deduct or withhold any amount as Withholding Taxes for United States federal income tax purposes for the period during which such Form W-9 is in effect and during which Kos does not know or have reason to know that it is, by reason of this Agreement, a financed entity in a conduit financing arrangement.

7.9.2 Additional Withholding Taxes. If, as a result of any change in the corporate status or location of Payor, or the permitted assignment of this Agreement by Payor, additional Withholding Taxes become due on payments from Payor or its permitted assignee to Payee that would not have been due absent such change in corporate status or location or permitted assignment, and Payee is not able to claim a credit or reimbursement for such tax, in whole or in part, then Payor will deduct Withholding Taxes in accordance with this Section 7.9, but will, in addition to the sums otherwise payable under this Agreement, pay to Payee such further sum as will ensure that, after deduction of Withholding Taxes on all such sums, the net amount received by Payee equals the amount that Payee would have received had the non-creditable or non-reimbursable amount of such additional Withholding Taxes not been deducted. To the extent that any such amount paid by Payor to Payee in accordance with this Section 7.9 is in fact subsequently able to be claimed by Payee as a credit or reimbursement for such tax otherwise deducted, then Payee will pay such amount to Payor.

8.2.3 In order for rights under Licensed Technology to be validly granted to a Sublicensee, the Sublicense Agreement with such Sublicensee must be consistent with the following terms and conditions of this Agreement, and will include provisions for the benefit of Jerini corresponding to Sections 3.4, 4, 7.8 and 12 (excluding Section 12.6). Kos undertakes to use all Commercially Reasonable Efforts to (i) procure the performance by any Sublicensee of the terms of each such Sublicense Agreement, and (ii) ensure that any Sublicensee shall comply with the applicable terms and conditions of this Agreement and of the Aventis Agreement. * * * the performance of its Affiliates and Sublicensees that are sublicensed as permitted herein, and the grant of any such sublicense will not relieve Kos of its obligations under this Agreement, except to the extent they are satisfactorily performed by such Sublicensee.

9. Filing, Prosecution, Maintenance, and Defense of Licensed Patents

9.1 Aventis Patents. This Section 9.1 will govern the Parties’ rights and responsibilities with respect to the filing, prosecution, maintenance and enforcement of the Aventis Patents.

9.1.1 Responsibility. The Parties acknowledge and agree that, under the Aventis Agreement, Sanofi-Aventis has the primary right to perform such activities with respect to the Aventis Patents. If Jerini becomes responsible for the preparation, filing, prosecution and maintenance of any Aventis Patents pursuant to the terms of the Aventis Agreement, then Jerini will bear any costs it incurs in connection with the preparation, filing, prosecution and maintenance of such Aventis Patents. Jerini will promptly notify Kos if Jerini receives any notice from Sanofi-Aventis under Section 7.4 of the Aventis Agreement and will continue to prosecute or maintain the Aventis Patents in the Territory.

9.1.2 Enforcement.

(a) Initiation. Kos and Jerini will each promptly notify the other in writing of any alleged or threatened infringement of the Aventis Patents based on the development or commercialization of a product in the Licensed Field by a Third Party. Pursuant to the terms of the Aventis Agreement, Sanofi-Aventis will have the first right to prosecute any such infringement. If Sanofi-Aventis does not exercise such right, as described in Section 7.5 of the Aventis Agreement, then Kos will have the right, but not the obligation, to prosecute any such infringement in the Licensed Field in the Territory. If Kos does not commence an infringement action against the alleged or threatened infringement within sixty (60) days following the detection of the alleged infringement, then Jerini may commence litigation with respect to the alleged or threatened infringement at its own expense.

(b) Cooperation. In the event a Party brings an infringement action pursuant to Section 9.1.2(a), the other Party will cooperate fully, including, if required to bring such action, the furnishing of a power of attorney or to join such action as a necessary party. Neither Party will have the right to settle any patent infringement litigation under this Section 9.1.2 without the express written consent of such other Party which consent will not be unreasonably withheld. The Party commencing the litigation will provide the other Party with copies of all pleadings and other material documents filed with the court and will consider reasonable input from the other Party during the course of the proceedings.

(c) Recovery. Except as otherwise agreed by the Parties in connection with a cost sharing arrangement or as otherwise required by Section 7.5.5 of the Aventis Agreement, any recovery realized as a result of such litigation described in Section 9.1.2(a) of this Agreement (whether by way of settlement or otherwise) will be first allocated to * * *.

9.2 Other Licensed Patents. This Section 9.2 will govern the Parties’ rights and responsibilities with respect to the filing, prosecution, maintenance and enforcement of Licensed Patents other than the Aventis Patents (the “Jerini Licensed Patents”).

9.2.1 Responsibility. Jerini will be responsible for the preparation, filing, prosecution and maintenance of the Jerini Licensed Patents in the Territory through patent counsel of its choice. Jerini will provide Kos with copies of all official correspondence received from the U.S. PTO, (or, if requested by Kos, from counterpart agencies in other countries) and

with any proposed substantive responses thereto sufficiently in advance for Kos to provide comments and suggestions on such proposed responses which will be delivered in a timely fashion. Jerini will bear any costs it incurs in connection with the preparation, filing, prosecution and maintenance of the Jerini Licensed Patents. Jerini will give notice to Kos in a timely manner of any decision to cease prosecution and/or maintenance, or not to proceed with an extension, of any Jerini Licensed Patent and, in such case, shall permit Kos at Kos’s sole discretion, to continue prosecution or maintenance or proceed with the extension at its own expense. If Kos elects to continue prosecution or maintenance or to proceed with the extension, Jerini shall execute such documents and perform such acts * * * as may be reasonably necessary to permit Kos to continue such prosecution and maintenance or to proceed with the extension, and any such patents and patent applications shall not be considered as Licensed Patents and Kos shall no longer have the obligation to make any payments with regard to such patents or patent applications under this Agreement.

9.2.2 Enforcement.

(a) Initiation. Kos and Jerini will each promptly notify the other in writing of any alleged or threatened infringement of the Jerini Licensed Patents based on the development or commercialization of a product in the Licensed Field by a Third Party in the Territory. Kos will have the first right, but not the obligation, to prosecute any such infringement. If Kos does not commence an infringement action against the alleged or threatened infringement within sixty (60) days following the detection of the of alleged infringement, then Jerini may commence litigation with respect to the alleged or threatened infringement at its own expense.

(b) Cooperation. In the event a Party brings an infringement action pursuant to Section 9.2.2(a), the other Party will cooperate fully, including, if required to bring such action, the furnishing of a power of attorney or to join such action as a necessary party. Neither Party will have the right to settle any patent infringement litigation under this Section 9.2.2 in a manner that diminishes the rights or interest of the other Party without the express written consent of such other Party which consent will not be unreasonably withheld. The Party commencing the litigation will provide the other Party with copies of all pleadings and other documents filed with the court and will consider reasonable input from the other Party during the course of the proceedings.

(c) Recovery. Except as otherwise agreed by the Parties in connection with a cost sharing arrangement, any recovery realized as a result of such litigation described in Section 9.2.2(a) (whether by way of settlement or otherwise) will be first allocated* * *.

9.3 Defense of Infringement Claims. If the manufacture, sale or use of a Licensed Product pursuant to this Agreement results in, or may result in, any claim, suit, or proceeding by a Third Party alleging patent infringement by Kos (or its Affiliates or Sublicensees), Kos will promptly notify Jerini thereof in writing. Kos (or its Affiliates or Sublicensees) will have the exclusive right to defend and control the defense of any such claim, suit or proceeding at its own expense, using counsel of its own choice; provided, that Kos (and its Affiliates and Sublicensees) may enter into any settlement which admits or concedes that any aspect of the Licensed Patents are invalid or unenforceable only with the prior written consent of Jerini. Kos will keep Jerini reasonably informed of all material developments in connection with any such claim, suit, or proceeding. Kos agrees to provide Jerini with copies of all pleadings filed in such action and to allow Jerini reasonable opportunity to participate in the

defense of the claims. Jerini will cooperate in the patent infringement defense and will furnish such records, information and testimony, provide such witnesses and attend such conferences, discovery proceedings, hearings, trials and appeals as may be reasonably requested in connection with the defense of any such claim. * * *.

9.4 Patent Term Restoration. In consultation with Kos, Jerini will determine for which of the Licensed Patents, if any, Jerini will seek at its own expense patent term extension due to delay(s) in obtaining Marketing Approval pursuant to 35 U.S.C. Section 156, or any successor law in the Territory, and will be responsible for submitting the application for patent term restoration to U.S. PTO. Any patent term extension will be regarded as Licensed Patents regardless who, due to applicable law, may be the owner thereof. Jerini will keep Kos fully informed of its efforts to obtain such extension.

9.5 Consequences of Patent Challenge.

9.5.1 Termination on Patent Challenge. Jerini will be permitted to terminate this Agreement by written notice effective upon receipt if Kos or its Affiliates directly, or indirectly through assistance granted to a Third Party, commence any interference or opposition proceeding, challenge the validity or enforceability of, or oppose any extension of or the grant of a supplementary protection certificate with respect to, any Licensed Patents or its foreign equivalents (each such action a “Patent Challenge”); provided, that such termination right will expire one (1) year after such interference or opposition becomes known to Jerini.

9.5.2 Sublicensees. Kos will include provisions in all Sublicense Agreements providing that if the Sublicensee or its Affiliates directly, or indirectly through assistance granted to a Third Party, undertake a Patent Challenge with respect to any Licensed Patents or its foreign equivalent, Kos will be permitted to terminate such Sublicense Agreement. If a Sublicensee directly, or indirectly through assistance granted to a Third Party, undertakes a Patent Challenge of any such patent, then Kos upon receipt of notice from Jerini of such Patent Challenge will terminate the applicable Sublicense Agreement. If Kos fails to so terminate such Sublicense Agreement, Jerini may terminate this Agreement.

9.6 Orange Book Listing of Patents. In consultation with Kos, Jerini will determine which of the Licensed Patents, if any, will be submitted for inclusion in the Approved Drug Products with Therapeutic Equivalence Evaluations pursuant to 21 U.S.C. Section 355, or any successor law in the United States. Jerini will notify Kos in writing at least ten (10) Business Days prior to the deadline for any such submission, and Jerini will submit the designated Patents in accordance with applicable Law. Jerini and Kos each will notify the other of any certification filed by any Third Party under the U.S. Drug Price Competition and Patent Term Restoration Act of 1984 claiming that a Licensed Patent is invalid or that infringement of a Licensed Patent will not arise from the manufacture, use, offer for sale, sale or importation product by a Third Party.

12.6.1 Subject to applicable rules and regulations of any applicable governmental authority or stock exchange, as soon as practicable following the date hereof, the Parties will issue a joint press release announcing the existence of this Agreement in the form of the draft press release attached hereto as Exhibit E. For subsequent press releases and other written public disclosures (other than filings that are covered by Sections 12.6.2, 12.6.3, 12.6.4 and 12.7 below) relating to this Agreement or the Parties’ relationship hereunder (each, a “Public Disclosure”), each Party will use reasonable efforts to submit to the other Party a draft of such Public Disclosures for review and comment by the other Party at least two (2) full Business Days prior to the date on which such Party plans to release such Public Disclosure, and will review and consider in good faith any comments provided in response.

12.6.2 If a Party is unable to comply with the foregoing notice requirement because of a legal obligation or stock exchange requirement to make more rapid disclosure or a legal requirement not to make disclosures to any persons prior to public filings, such Party will not be in breach of this Agreement but will in that case give telephone and email notice to a senior executive of the other Party and provide a draft disclosure with as much notice as possible prior to the release of such Public Disclosure.

12.6.3 The Parties will coordinate in advance with each other in connection with the redaction of certain provisions of this Agreement with respect to any filings with the U.S. Securities and Exchange Commission (“SEC”) or German Bundesanstalt für Finanzdienstleistungsaufsicht (“BAFIN”) of such Party or any of its Affiliates, and each Party will use reasonable efforts to seek confidential treatment for such terms; provided, that each Party will ultimately retain control over what information to disclose to the SEC, BAFIN, or any other such agencies, as the case may be, and provided further that the Parties will use their reasonable efforts to file redacted versions with any governing bodies which are consistent with redacted versions previously filed with any other governing bodies.

the other Party; provided, that (a) Jerini will have the right to disclose the terms and conditions of this Agreement to Sanofi-Aventis to the extent required by the Aventis Agreement, (b) either Party may make any filings of this Agreement required by law or regulation in any country so long as such Party uses its reasonable efforts to obtain confidential treatment for portions of this Agreement as available and (c) a Party may publicly disclose, without regard to the preceding requirements of this Section 12.7, information that was previously disclosed in compliance with such requirements.

12.8 Additional Obligations Under Aventis Agreement. As a sublicensee of Jerini under the Aventis Agreement, Kos agrees to comply with the terms of Section 8 of the Aventis Agreement, the full text of which is set forth on Exhibit F, in connection with (a) Kos’s use of Confidential Information of Sanofi-Aventis that Jerini may provide to Kos, (b) Kos’s publication and presentation of any results or other information relating to any Licensed Product.

12.9 Provision of Information to Sanofi-Aventis. Jerini will provide

Kos with copies of all proposed disclosures to Sanofi-Aventis of information relating to this Agreement, as contemplated in Sections 3.1.1, 7.8, and 12.7 hereof, sufficiently in advance for Kos to provide comments and suggestions on such proposed disclosures which will be delivered in a timely fashion. Jerini will reasonably consider any such comments or suggestions provided by Kos.

13. Term and Termination

13.1 Term. This Agreement will be effective on the date (the “Effective Date”): (i) of the written determination by the Parties, to be made within ten (10) days after the Execution Date, that no filing under the HSR Act is necessary, or (ii) if no such determination is made, of expiration or termination of any waiting period and extension thereof applied to this Agreement and the transactions contemplated hereunder, under the HSR Act; provided however that Section 4.7 (HSR Act), and all sections necessary to give effect to Section 4.7, will be effective on the date hereof. The term of this Agreement will commence as of the Effective Date and, unless earlier terminated in accordance with this Section 13, and will continue so long as either Party is obligated to pay royalties to the other Party hereunder (the “Term”).

13.2 Termination for Material Breach.

13.2.1 Any material failure by a Party (“Breaching Party”) to comply with any of its material obligations contained in this Agreement (such failure a “Material Breach”) will entitle the other Party (“Non-Breaching Party”) to give to the Breaching Party notice specifying the nature of the Material Breach, requiring the Breaching Party to make good or otherwise cure such Material Breach.

13.2.2 If such Material Breach is not cured within * * * after the receipt of notice pursuant to Section 13.2.1 above, the Non-Breaching Party will be entitled to terminate this Agreement on notice effective upon receipt to the Breaching Party and without prejudice to any of its other rights conferred on it by this Agreement and other remedies available under applicable law, except that if such Material Breach relates to Kos’s obligations with respect to a Licensed Product in Canada, Jerini’s sole and exclusive remedy therefor shall be to terminate Kos’s rights to such Licensed Product in Canada (after which the Territory hereunder with respect thereto shall consist solely of the United States).

13.2.3 If Kos is entitled to terminate this Agreement pursuant to Section 13.2.2 due to Jerini’s Material Breach, then Kos will, by notice to Jerini, (a) terminate this Agreement in its entirety, or (b) terminate this Agreement in part as described in further detail in Section 13.6.5.

13.3 Termination at Will. Kos may terminate this Agreement at will upon * * * days’ notice to Jerini; provided, that Jerini may accelerate the effective date of such termination by * * *, such that the effective date of such termination occurs at any time after * * * days of such * * * day notice period have elapsed.

13.4 Termination of Licenses Under Aventis Agreement. In the event that Jerini receives any notice of breach of the Aventis Agreement from Sanofi-Aventis, Jerini will immediately provide Kos with a copy of such notice. Jerini authorizes Kos to cure any such breach on Jerini’s behalf unless Jerini evidences to Kos’s reasonable satisfaction that it has done so; provided, that Jerini shall indemnify Kos against the amount of any payments made by Kos directly to Sanofi-Aventis in connection with such cure and, at Kos’s election, the amount of such payments may be credited against any amounts otherwise payable by Kos to Jerini hereunder. Notwithstanding anything to the contrary in this Agreement, the licenses granted to Kos under the Aventis Patents will terminate automatically upon expiration or earlier termination of the Aventis Agreement. If the Aventis Agreement is terminated by Sanofi-Aventis or Jerini prior to the expiration thereof and Kos is unable to obtain a license directly from Sanofi-Aventis, then, within * * * following such termination, * * * calculated as follows:

***.

Jerini will reasonably assist Kos in negotiating an agreement directly between Kos and Sanofi-Aventis promptly following the Effective Date which would ensure the continuation of Kos’s rights hereunder on terms no less favorable than contained in this Agreement if the Aventis Agreement were to be terminated.

13.5 Termination for Failure to Execute Equity Investment Agreement. Jerini will have the right to terminate this Agreement (and refund any amounts theretofore paid by Kos to Jerini) by notice to Kos if Kos or Kos Pharmaceuticals, Inc.: (i) does not promptly after the Effective Date execute the Agreement on Equity Investment attached to this Agreement as Exhibit D (the “Equity Agreement”), (ii) does not deliver thereafter the two originals of the subscription certificate as set forth in § 2.2 of the Equity Agreement, or (iii) does not thereafter submit the lock-up declaration as set forth in § 2.2 of the Equity Agreement, and in each case Jerini and its Affiliates have taken all actions necessary to enable Kos or its Affiliate to do so and have, to the extent applicable, executed and delivered such agreements themselves; provided, that such failure is not cured within thirty (30) days after notice thereof from Jerini to Kos.

13.6 Consequences of Expiration and Termination.

13.6.1 Expiration of Term.

(a) Upon expiration of the Royalty Term, Kos will have a non-exclusive, irrevocable, perpetual, fully-paid license, with the right to sublicense through multiple tiers of sublicenses, under the Licensed Technology to research, develop, make, use, sell, offer for sale, manufacture and import Licensed Product in the Licensed Field in the Territory.

(a) All rights and licenses granted by Jerini to Kos under this Agreement will terminate immediately.

(b) Kos will upon Jerini’s request and at no cost to Kos, transfer and assign to Jerini promptly but no later than sixty (60) days after termination of the Agreement, all assets and rights as may be necessary for Jerini to continue with the development and commercialization of the Licensed Product in the Territory. Without limitation, Kos will assign to Jerini upon request any of the following: (i) all of Kos’s right, title and interest in and to any agreements between Kos and Third Parties that are freely assignable by Kos and that relate to the development or Commercialization of any Licensed Product; and (ii) all of Kos’s right, title and interest in and to any registrations and design patents (to the extent directed to ornamental features of the applicable Licensed Product) for any of the foregoing and any Internet domain name registrations for such trademarks and slogans, all to the extent they relate to a Licensed Product. To the extent that any agreement described in this Section 13.6.2(c) is not assignable by Kos, then such agreement will not be assigned, and upon the request of Jerini, Kos will cooperate in good faith to allow Jerini to obtain and to enjoy the benefits of such agreement in the form of a license or other right to the extent Kos has the right and ability to do so.

(c) Kos will, upon Jerini’s written request, * * * transfer to Jerini or its designee, the management and continued performance of any clinical trials for Licensed Product ongoing as of the effective date of such termination.

13.6.3 Sale of Inventory. During the * * * period following full or partial termination or expiration of this Agreement, Kos may, subject to Section 13.6.2(d) above, sell its then-existing inventory of Licensed Products for the Licensed Field in the Territory and will pay all amounts due to Jerini hereunder with respect to any Net Sales of such inventory occurring during such * * * period. Additionally, the Parties’ rights and obligations under this Agreement will continue during such * * * after the expiration of this Agreement, to the extent applicable to such sales.

13.6.4 Transfer Plan. With respect to any termination of this Agreement, the Parties will establish a transfer plan that will provide for the complete transfer of the rights and assets as required pursuant to Section 13.6.2 above from Kos or its Sublicensees to Jerini, with the goal of minimizing the disruption and delay in the development or commercialization of the Licensed Product.

13.6.5 Partial Termination for Jerini Breach. If Kos terminates this Agreement in part pursuant to Section 13.2.3(b), this Agreement will terminate except that the Parties’ rights and obligations under Sections 7, 8 (excluding 8.1.3 and 8.3), and 13, and the surviving provisions described in Section 13.6.6 below, will continue in full force and effect.

13.6.6 Survival. Expiration or termination of this Agreement will not relieve the Parties of any obligation accruing prior to such expiration or termination. The provisions of Sections 1, 4.2, 7.7, 7.8, 7.9, 10, 11.3, 12, 13.6, 14, 15, and 16 will survive any termination or expiration of this Agreement.

14. Indemnification and Insurance

14.1 Indemnification by Jerini. Jerini will indemnify Kos, its Affiliates, and their respective directors, officers, shareholders, employees and agents, and defend and hold each of them harmless, from and against any losses, damages, liabilities, costs and expenses (including reasonable attorneys’ fees and expenses) (collectively, “Losses”) in connection with any liability suits, investigations, claims or demands by Third Parties (“Third Party Claims”) to the extent arising from or occurring as a result of or in connection with (i) any theory of product liability (including actions in the form of tort, warranty or strict liability) concerning the manufacture or Commercialization of Licensed Products by or on behalf of Jerini or its Affiliates, licensees, designees and agents or the manufacture or handling of Licensed Products by or on behalf of Jerini or its Affiliates, licensees, designees and agents prior to delivery thereof to Kos or its designee, (ii) any breach by Jerini of its representations, warranties or obligations under this Agreement, or (iii) the gross negligence or willful misconduct by or on behalf of Jerini or its Affiliates, licensees, designees and agents; except, in each case, to the extent that Jerini is entitled to seek indemnification from Kos for such Losses pursuant to Section 14.2 below.

14.2 Indemnification by Kos. Kos will indemnify Jerini, its Affiliates, and their respective directors, officers, shareholders, employees and agents, and defend and save each of them harmless, from and against any Losses in connection with any Third Party Claims arising from or occurring as a result of or in connection with: (i) any theory of product liability (including actions in the form of tort, warranty or strict liability) concerning the manufacture by or on behalf of Kos or its Affiliates, licensees, designees and agents (other than by or behalf of Jerini or its Affiliates) or Commercialization of Licensed Products by Kos or its Affiliates, licensees, designees and agents, the handling of Licensed Product after its delivery by or on behalf of Jerini or its designee, (ii) any breach by Kos of its representations, warranties or

obligations under this Agreement, or (iii) the gross negligence or willful misconduct of Kos, its Affiliates or Sublicensees, designees and agents; except, in each case, to the extent that Kos is entitled to seek indemnification from Jerini for such Losses pursuant to Section 14.1 above.

14.3 Indemnification Procedure.

14.3.1 Notice of Claim. The Party intending to request indemnification under this Section 14 (the “Indemnified Party”) will give the Party from which it seeks indemnification under this Section 14 (the “Indemnifying Party”) prompt written notice (an “Indemnification Claim Notice”) of any Third Party Claim or discovery of fact upon which such Indemnified Party intends to base a request for indemnification under Section 14.1 or Section 14.2; provided, however, that the failure to give such prompt written notice will not relieve Indemnifying Party of its indemnification obligation under this Agreement except and only to the extent that the Indemnifying Party is actually prejudiced as a result of such failure. In no event will the Indemnifying Party be liable for any Losses that result from any delay in providing such notice. Each Indemnification Claim Notice must contain a description of the Third Party Claim and the nature and amount of such Loss (to the extent that the nature and amount of such Loss are known at such time). The Indemnified Party will furnish promptly to the Indemnifying Party copies of all papers and official documents received in respect of any Third Party Claims or Losses. All indemnification claims in respect of an Indemnified Party, its Affiliates or their respective directors, officers, employees and agents (collectively, the “Indemnitees” and each an “Indemnitee”) will be made solely by the Indemnified Party.

14.3.2 Control of Defense. At its option, the Indemnifying Party may assume the defense of any Third Party Claim by giving written notice to the Indemnified Party within 30 days after the Indemnifying Party’s receipt of an Indemnification Claim Notice. Upon assuming the defense of a Third Party Claim, the Indemnifying Party may appoint as lead counsel in the defense of the Third Party Claim any legal counsel selected by the Indemnifying Party. In the event the Indemnifying Party assumes the defense of a Third Party Claim, the Indemnified Party will immediately deliver to the Indemnifying Party all original notices and documents (including court papers) received by any Indemnitee in connection with the Third Party Claim. Should the Indemnifying Party assume the defense of a Third Party Claim, the Indemnifying Party will not be liable to the Indemnified Party or any other Indemnitee for any legal expenses subsequently incurred by such Indemnified Party or other Indemnitee in connection with the analysis, defense or settlement of the Third Party Claim.

14.3.3 Right to Participate in Defense. Without limiting Section 14.3.2 above, any Indemnitee will be entitled to participate in, but not control, the defense of such Third Party Claim and to employ counsel of its choice for such purpose; provided, that such employment will be at the Indemnitee’s own expense unless (i) the employment thereof has been specifically authorized by the Indemnifying Party in writing, or (ii) the Indemnifying Party has failed to assume the defense and employ counsel in accordance with Section 14.3.2 (in which case the Indemnified Party will control the defense).

14.3.4 Settlement. With respect to any Losses relating solely to the payment of money damages in connection with a Third Party Claim and that will not result in the Indemnitee’s becoming subject to injunctive or other relief or otherwise adversely affect the business of the Indemnitee in any manner, and as to which the Indemnifying Party will have acknowledged in writing the obligation to indemnify the Indemnitee hereunder, the Indemnifying Party will have the sole right to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss, on such terms as the Indemnifying Party, in its sole

discretion, will deem appropriate, and will transfer to the Indemnified Party all amounts which said Indemnified Party will be liable to pay prior to the time prior to the entry of judgment. With respect to all other Losses in connection with Third Party Claims, where the Indemnifying Party has assumed the defense of the Third Party Claim in accordance with Section 14.3.2, the Indemnifying Party will have authority to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss provided it obtains the prior written consent of the Indemnified Party (which consent will be at the Indemnified Party’s sole and absolute discretion). The Indemnifying Party will not be liable for any settlement or other disposition of a Loss by an Indemnitee that is reached without the written consent of the Indemnifying Party. Regardless of whether the Indemnifying Party chooses to defend or prosecute any Third Party Claim, no Indemnitee will admit any liability with respect to, or settle, compromise or discharge, any Third Party Claim without the prior written consent of the Indemnifying Party.

14.3.5 Cooperation. The Indemnified Party will, and will cause each other Indemnitee to, cooperate in the defense or prosecution thereof and will furnish such records, information and testimony, provide such witnesses and attend such conferences, discovery proceedings, hearings, trials and appeals as may be reasonably requested in connection with the defense or prosecution of any Third Party Claim. Such cooperation will include access during normal business hours afforded to the Indemnifying Party to, and reasonable retention by the Indemnified Party of, records and information that are reasonably relevant to such Third Party Claim, and making Indemnitees and other employees and agents available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder, * * *.

14.4 Expenses. Except as provided above, the reasonable and verifiable costs and expenses, including fees and disbursements of counsel, incurred by the Indemnified Party in connection with any claim * * * Indemnifying Party, without prejudice to the Indemnifying Party’s right to contest the Indemnified Party’s right to indemnification and subject to refund in the event the Indemnifying Party is ultimately held not to be obligated to indemnify the Indemnified Party.

14.5 Insurance. Each Party will obtain and keep in force, through self insurance or otherwise, in a form reasonably acceptable to the other Party hereto, insurance in scope and amount as required by law applicable to a Party’s activities hereunder and such additional amounts as may be reasonably necessary to cover such Party’s indemnity obligations under this Agreement with scope and coverage as is normal and customary in the industry within the Territory for parties similarly situated, but in no event in an amount less than *** per occurrence and in the aggregate. It is understood that such insurance will not be construed to limit a Party’s liability with respect to its indemnification obligations under this Section 14. Each Party will, except to the extent self insured, provide to the other Party upon request, a certificate evidencing the insurance such Party is required to obtain and keep in force under this Section 14. Such certificate will provide that such insurance will not expire or be cancelled or modified without at least thirty (30) days’ prior notice to the other Party.

15. Limitation of Liability

IN NO EVENT WILL EITHER PARTY BE LIABLE FOR THE OTHER PARTY’S LOST PROFITS, LOSS OF DATA, OR FOR ANY SPECIAL, INDIRECT, INCIDENTAL, CONSEQUENTIAL OR PUNITIVE DAMAGES, HOWEVER CAUSED, ON ANY THEORY OF LIABILITY AND WHETHER OR NOT SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, ARISING

UNDER ANY CAUSE OF ACTION AND ARISING IN ANY WAY OUT OF THIS AGREEMENT. THE FOREGOING LIMITATIONS WILL NOT APPLY TO AN AWARD OF ENHANCED DAMAGES AVAILABLE UNDER THE PATENT LAWS FOR WILLFUL PATENT INFRINGEMENT AND WILL NOT LIMIT EITHER PARTY’S OBLIGATIONS TO THE OTHER PARTY UNDER SECTIONS 12 AND 14 OF THIS AGREEMENT.

16. Miscellaneous

16.1 Assignment. Without the prior written consent of the other Party hereto (which may be granted at the other Party’s discretion), neither Party will sell, transfer, assign, delegate, pledge or otherwise dispose of, whether voluntarily, involuntarily, by operation of law or otherwise, this Agreement or any of its rights or duties hereunder; provided, that either Party may assign or transfer this Agreement or any of its rights or obligations hereunder without the consent of the other Party (a) to any Affiliate of the assigning Party; or (b) to any Third Party with which it merges or consolidates, or to which it transfers all or substantially all of its assets to which this Agreement relates. Any assignee will assume in writing all of the assigning Party’s obligations under this Agreement. Any purported assignment or transfer in violation of this Section 16.1 will be void ab initio and of no force or effect.

16.2 Essential Basis. The Parties acknowledge and agree that the disclaimers, exclusions and limitations of liability set forth in Section 11.3 and 15 form an essential basis of this Agreement, and that, absent any of such disclaimers, exclusions or limitations of liability, the terms of this Agreement, including, without limitation, the economic terms, would be substantially different.

16.3 Severability. If any provision of this Agreement is held to be illegal, invalid or unenforceable under any present or future law, (a) such provision will be fully severable, (b) this Agreement will be construed and enforced as if such illegal, invalid or unenforceable provision had never been a part hereof, (c) the remaining provisions of this Agreement will remain in full force and effect and will not be affected by the illegal, invalid or unenforceable provision or by its severance herefrom, and (d) in lieu of such illegal, invalid or unenforceable provision, there will be added automatically as a part of this Agreement a legal, valid and enforceable provision as similar in terms to such illegal, invalid or unenforceable provision as may be possible and reasonably acceptable to the Parties. To the fullest extent permitted by applicable law, each Party hereby waives any provision of law that would render any provision prohibited or unenforceable in any respect.

16.4 Governing Law; Dispute Resolution.

16.4.1 This Agreement, and any disputes between the Parties related to or arising out of this Agreement (including the Parties’ relationship created hereby, the negotiations for and entry into this Agreement, its conclusion, binding effect, amendment, coverage, termination, or the performance or alleged non-performance of a Party of its obligations under this Agreement) (each a “Dispute”), will be governed by

the laws of the State of New York, USA without reference to any choice of law principles thereof that would cause the application of the laws of a different jurisdiction.

16.4.2 In the event of any Dispute, a Party may notify the other Party in writing of such Dispute, and the Parties will try to settle such Dispute amicably between themselves. If the Parties are unable to resolve the Dispute within 20 days of receipt of the written notice by the other Party, such Dispute will be referred to the Chief Executive Officers of each of the

Parties (or their respective designees) who will use their good faith efforts to resolve the Dispute within 30 days after it was referred to the Chief Executive Officers.

16.4.3 Any Dispute that is not resolved as provided in Section 16.4.2, whether before or after termination of this Agreement, will be resolved by litigation in the courts of competent jurisdiction located in New York, New York, USA without giving effect to conflict of laws principles. Each Party hereby agrees to the exclusive jurisdiction of such courts and waives any objections as to the personal jurisdiction or venue of such courts.

16.4.4 Notwithstanding the foregoing, nothing in this Section 16.4 will limit either Party’s right to seek immediate temporary injunctive or other temporary equitable relief whenever the facts or circumstances would permit a Party to seek such relief in a court of competent jurisdiction.

This Agreement including the Guaranties and Exhibits attached hereto and the Confidentiality Agreement, each of which is hereby incorporated in and made part of this Agreement by reference, set forth and constitute the entire agreement and understanding between the Parties with respect to the subject matter hereof and supersede and merge all prior negotiations, representations, agreements and understandings, whether written or oral, regarding the subject matter hereof.

16.7 Waiver. Any term or condition of this Agreement may be waived at any time by the Party that is entitled to the benefit thereof, but no such waiver will be effective unless set forth in a written instrument duly executed by or on behalf of the Party waiving such term or condition. The waiver by either Party hereto of any right hereunder or of claims based on the failure to perform or a breach by the other Party will not be deemed a waiver of any other right hereunder or of any other breach or failure by said other Party whether of a similar nature or otherwise. The failure of a Party to insist on the performance of any obligation hereunder will not be deemed to be a waiver of such obligation.

16.8 Counterparts. This Agreement may be executed in two or more counterparts, each of which will be deemed an original, but all of which together will constitute one and the same instrument.

16.9 No Benefit to Third Parties. The representations, warranties, covenants and agreements set forth in this Agreement are for the sole benefit of the Parties and their successors and permitted assigns, and they will not be construed as conferring any rights on any other parties.
