ARTICLE 9.

* CONFIDENTIAL TREATMENT REQUESTED. OMITTED PORTIONS FILED WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 406 PROMULGATED UNDER THE SECURITIES ACT OF 1933, AS AMENDED.

30

(iv) Company’s, its Affiliates’ or any Permitted Seller’s failure to comply in any material respect with Applicable Laws in connection with the performance of its obligations hereunder; or

(v) Any other activities conducted by Company, its Affiliates or Permitted Sellers with respect to any Compound or Modified Compound which activities are conducted after the Effective Date.

Notwithstanding the foregoing provisions of this Section 9.1(a), the Company shall not be required to indemnify Lilly or its Affiliates or their officers, directors, employees and agents pursuant to this Section 9.1(a) against any Damages to the extent that (1) such Damages result from or arise out of Lilly’s material breach of any of its obligations under this Agreement or any of its representations or warranties under this Agreement, (2) such Damages result from or arise out of any activities of Lilly under the Services Agreement or (3) such Damages result from or arise out of the negligence or willful misconduct of Lilly or its Affiliates or their officers, directors, employees or agents.

(b) Lilly’s Obligation. Lilly shall defend, indemnify and hold harmless Company, its Affiliates and their officers, directors, employees and agents against any and all Damages incurred by any of them resulting from or arising out of:

9.2 Notice and Opportunity to Defend.

(a) Notice. Promptly after receipt by a Party hereto of notice of any claim which could give rise to a right to indemnification pursuant to Section 9.1, such Party (the “Indemnitee”) will give the other Party (the “Indemnifying Party”) written notice describing the claim in reasonable detail. The failure of an Indemnitee to give notice in the manner provided herein will not relieve the Indemnifying Party of its obligations

* CONFIDENTIAL TREATMENT REQUESTED. OMITTED PORTIONS FILED WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 406 PROMULGATED UNDER THE SECURITIES ACT OF 1933, AS AMENDED.

31

under this Article 9, except to the extent that such failure to give notice materially prejudices the Indemnifying Party’s ability to defend such claim.

(b) Defense of Action. In case any action that is subject to indemnification under this Article 9 shall be brought against an Indemnitee and it has given written notice to the Indemnifying Party of the commencement thereof, the Indemnifying Party shall be entitled to participate and, if it so desires, to assume the defense with counsel reasonably satisfactory to such Indemnitee. After notice from the Indemnifying Party to the Indemnitee of its election to assume the defense, the Indemnifying Party shall not be liable to such Indemnitee under this Article 9 for any fees of other counsel or any other expenses, in each case subsequently incurred by such Indemnitee in connection with the defense.

(c) Indemnitee’s Separate Counsel. Notwithstanding the foregoing, the Indemnitee shall have the right to employ separate counsel and to participate in the defense of such action at the Indemnitee’s expense, provided however, that the Indemnifying Party shall bear the reasonable fees, costs and expenses of such separate counsel if: (i) the use of counsel chosen by the Indemnifying Party to represent the Indemnitee would present such counsel with a conflict of interest, and the Indemnifying Party does not elect to engage new counsel without such a conflict; (ii) the Indemnifying Party shall not have employed counsel reasonably satisfactory to the Indemnitee to represent the Indemnitee within a reasonable time after notice of the institution of such action; or (iii) the Indemnifying Party shall authorize the Indemnitee in writing to employ separate counsel at the Indemnifying Party’s expense.

(d) Settlement. If an Indemnifying Party assumes the defense of such action, no compromise or settlement thereof may be effected by the Indemnifying Party without the Indemnitee’s written consent, which consent shall not be unreasonably withheld or delayed.

(e) Conduct of Defense. Notwithstanding anything to the contrary in this Section 9.2, the Party conducting the defense of a claim will (1) keep the other Party informed on a reasonable and timely basis as to the status of the defense of such claim (but only to the extent such other Party is not participating jointly in the defense of such claim), and (2) conduct the defense of such claim in a prudent manner.

9.3 Survival. The provisions of this Article 9 will survive any termination or expiration of this Agreement. Each Indemnified Party’s rights under this Article 9 will not be deemed to have been waived or otherwise affected by such Indemnified Party’s waiver of the breach of any representation, warranty, agreement or covenant contained in or made pursuant to this Agreement, unless such waiver expressly and in writing also waives any or all of the Indemnified Party’s right under this Article 9.
