All persons who have executed this Agreement or the Manufacturing Agreement on behalf of Lilly, or who will execute on behalf of Lilly any agreement or instrument contemplated by this Agreement or the Manufacturing Agreement, have been duly authorized to do so by all necessary corporate action.

Dura and Lilly shall discuss any response to observations or notifications received in connection with any such inspection, investigation or other inquiry and each shall give the other an opportunity to comment upon any proposed response before it is made. In the event of disagreement concerning the form or content of such response, however, Lilly shall be responsible for deciding the appropriate form and content of any response with respect to any of its cited activities and Dura shall be responsible for deciding the appropriate form and content of any response with respect to any of its cited activities. 7.4 RECALL. Lilly and Dura shall each maintain such traceability records as may be necessary to permit a recall or field correction of any Products. Each party shall give telephonic notice (to be confirmed in writing) to the other within twenty-four (24) hours of the receipt of any information which indicates a recall may be necessary.

Dura shall neither disclose Lilly Proprietary Information to any third party nor use Lilly Proprietary Information for any purpose other than as set forth in this Agreement. Lilly shall treat as confidential all information of Dura of which Lilly becomes aware (whether in writing or orally or by sensory detection) in connection with this Agreement or the Manufacturing Agreement (collectively, "Dura Proprietary Information").

Lilly shall obtain no right or license of any kind under the Dura Proprietary Information except as set forth in this Agreement. 7.6 EXPENSES.

SECTION 8 INDEMNIFICATION 8.1 INDEMNIFICATION. (a) Lilly shall indemnify, defend and hold Dura (and its directors, officers, employees, and Affiliates) harmless from and against any and all Damages incurred or suffered by Dura (and its directors, officers, employees, and Affiliates) (excluding incidental or consequential Damages suffered or incurred by Dura directly (as opposed to incidental or consequential Damages suffered or incurred by third parties who are, in turn, seeking the same from Dura, which shall be covered by the indemnity set forth herein)) as a consequence of: (i) any breach of any representation or warranty made by Lilly in this Agreement, or in the Manufacturing Agreement, provided that, in the case of a breach of any representation or warranty made by Lilly in this Agreement, notice of a claim based upon any such breach is received by Lilly prior to the expiration of -34- such representation and warranty pursuant to Section 10.4; (ii) any failure to perform duly and punctually any covenant, agreement or undertaking on the part of Lilly contained in this Agreement or in the Manufacturing Agreement; (iii) any material misrepresentation in or material omission from any agreement, instrument or document delivered by Lilly pursuant to the terms of this Agreement, or the Manufacturing Agreement; or (iv) any Excluded Liabilities. (b) Dura shall indemnify, defend and hold Lilly (and its directors, officers, employees, and Affiliates) harmless from and against any and all Damages incurred or suffered by Lilly (and its directors, officers, employees, and Affiliates) (excluding incidental or consequential Damages suffered or incurred by Lilly directly (as opposed to incidental or consequential Damages suffered or incurred by third parties who are, in turn, seeking the same from Lilly, which shall be covered the indemnity set forth herein)) as a consequence of: (i) any breach of any representation or warranty made by Dura in this Agreement, or in the Manufacturing Agreement, provided that, in the case of a breach of any representation or warranty made by Dura in this Agreement, notice of a claim based upon any such breach is received by Dura prior to the expiration of such representation and warranty pursuant to Section 10.4; (ii) any failure to perform duly and punctually any covenant, agreement or undertaking on the part of -35- Dura contained in this Agreement or in the Manufacturing Agreement; (iii) any material misrepresentation in or material omission from any agreement, instrument or document delivered by Dura pursuant to the terms of this Agreement or the Manufacturing Agreement; or (iv) any Assumed Liabilities. 8.2 NOTICE AND OPPORTUNITY TO DEFEND. Promptly after receipt by a party hereto of notice of any claim which could give rise to a right to indemnification pursuant to Section 8.1, such party (the "Indemnified Party") shall give the other party (the "Indemnifying Party") written notice describing the claim in reasonable detail. The failure of an Indemnified Party to give notice in the manner provided herein shall not relieve the Indemnifying Party of its obligations under this Section, except to the extent that such failure to give notice materially prejudices the Indemnifying Party's ability to defend such claim. The Indemnifying Party shall have the right, at its option, to compromise or defend, at its own expense and by its own counsel, any such matter involving the asserted liability of the party seeking such indemnification. If the Indemnifying Party shall undertake to compromise or defend any such asserted liability, it shall promptly (and in any event not less than ten (10) days after receipt of the Indemnified Party's original notice) notify the Indemnified Party in writing of its intention to do so, and the Indemnified Party agrees to cooperate fully with the Indemnifying Party and its counsel in the compromise or defense against any such asserted liability. All reasonable costs and expenses incurred in connection with such cooperation shall be borne by the Indemnifying Party. If the Indemnifying Party elects not to compromise or defend the asserted liability, fails to notify the Indemnified Party of its election to compromise or defend as herein provided, fails to admit its obligation to indemnify under this Agreement with respect to the claim, or, if in the reasonable opinion of the Indemnified Party, the claim could result in the Indemnified Party becoming subject to injunctive relief or relief other than the payment of money damages that could materially adversely affect the ongoing business of the Indemnified Party in any manner, the Indemnified Party shall have the right, at its option, to pay, compromise or -36- defend such asserted liability by its own counsel and its reasonable costs and expenses shall be included as part of the indemnification obligation of the Indemnifying Party hereunder. Notwithstanding the foregoing, neither the Indemnifying Party nor the Indemnified Party may settle or compromise any claim over the objection of the other; PROVIDED, HOWEVER, that consent to settlement or compromise shall not be unreasonably withheld. In any event, the Indemnified Party and the Indemnifying Party may participate, at their own expense, in the defense of such asserted liability. If the Indemnifying Party chooses to defend any claim, the Indemnified Party shall make available to the Indemnifying Party any books, records or other documents within its control that are necessary or appropriate for such defense. Notwithstanding anything to the contrary in this Section 8.2, (i) the party conducting the defense of a claim shall (A) 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 (B) conduct the defense of such claim in a prudent manner, and (ii) the Indemnifying Party shall not cease to defend, settle or otherwise dispose of any claim without the prior written consent of the Indemnified Party (which consent shall not be unreasonably withheld). 8.3 INDEMNIFICATION PAYMENT OBLIGATION. No Indemnifying Party will have any obligations under Sections 8.l(a) or 8.1(b) until the cumulative aggregate amount of Damages incurred or suffered by the Indemnified Party which the Indemnifying Party is otherwise subject to under this Agreement exceeds *, at which time the entire cumulative aggregate amount of such Damages shall be covered. The provisions of this Section 8.3 shall not limit or otherwise affect the obligations of any Indemnifying Party under any other Section of this Agreement. 8.4 INDEMNIFICATION PAYMENT ADJUSTMENTS. The amount of any Damages for which indemnification is provided under this Section 8 shall be reduced to take account of any net tax benefit and shall be increased to take account of any net tax detriment arising from the incurrence or payment of any such Damages or from the receipt of any such indemnification payment and shall be reduced by the insurance proceeds received and any other amount recovered, if any, by the Indemnified Party with respect to any Damages; provided, however, * Certain confidential portions of this Exhibit were omitted by means of marking such portions with an asterisk (the "Mark"). This Exhibit has been filed with The Secretary of the Commission without the Mark pursuant to the Company's application requesting confidential treatment under Rule 24b-2 under the Securities Exchange Act of 1934, as amended. -37- that an Indemnified Party shall not be subject to an obligation to pursue an insurance claim relating to any Damages for which indemnification is sought hereunder. If any Indemnified Party shall have received any payment pursuant to this Section 8 with respect to any Damages and shall subsequently have received insurance proceeds or other amounts with respect to such Damages, then such Indemnified Party shall pay to the Indemnifying Party an amount equal to the difference (if any) between (i) the sum of the amount of those insurance proceeds or other amounts received and the amount of the payment by such Indemnifying Party pursuant to this Section 8 with respect to such Damages and (ii) the amount necessary to fully and completely indemnify and hold harmless such Indemnified Party from and against such Damages; PROVIDED, HOWEVER, in no event will such Indemnified Party have any obligation pursuant to this sentence to pay to such Indemnifying Party an amount greater than the amount of the payment by such Indemnifying Party pursuant to this Section 8 with respect to such Damages. 8.5 INDEMNIFICATION PAYMENT. Upon the final determination of liability and the amount of the indemnification payment under this Section 8, the appropriate party shall pay to the other, as the case may be, within ten (10) business days after such determination, the amount of any claim for indemnification made hereunder. 8.6 SURVIVAL. The provisions of Section 8 shall survive any termination of this Agreement and any termination of the Manufacturing Agreement. Each Indemnified Party's rights under Section 8 shall 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 this Agreement or the Manufacturing Agreement, unless such waiver expressly and in writing also waives any or all of the Indemnified Party's right under Section 8. SECTION 9 TERMINATION 9.1 TERMINATION. Anything herein to the contrary notwithstanding, this Agreement may be terminated as follows: -38- (a) TERMINATION FOR INSOLVENCY. If either Dura or Lilly (i) makes a general assignment for the benefit of creditors or becomes insolvent; (ii) files an insolvency petition in bankruptcy; (iii) petitions for or acquiesces in the appointment of any receiver, trustee or similar officer to liquidate or conserve its business or any substantial part of its assets; (iv) commences under the laws of any jurisdiction any proceeding involving its insolvency, bankruptcy, reorganization, adjustment of debt, dissolution, liquidation or any other similar proceeding for the release of financially distressed debtors; or (v) becomes a party to any proceeding or action of the type described above in (iii) or (iv) and such proceeding or action remains undismissed or unstayed for a period of more than sixty (60) days, then the other party may by written notice terminate this Agreement in its entirety with immediate effect. (b) TERMINATION FOR DEFAULT. (i) Dura and Lilly each shall have the right to terminate this Agreement with respect to a specific Product for default upon the other's failure to comply in any material respect with the terms and conditions of this Agreement or the Manufacturing Agreement that relate to such specific Product. At least ninety (90) days prior to any such termination for default, the party seeking to so terminate shall give the other written notice of its intention to terminate this Agreement in accordance with the provisions of this Section 9.1(b), which notice shall set forth the default(s) which form the basis for such termination. If the defaulting party fails to correct such default(s) within ninety (90) days after receipt of notification, or if the same cannot reasonably be corrected or remedied within ninety (90) days, then if the -39- defaulting party has not commenced curing said default(s) within said ninety (90) days and be diligently pursuing completion of same, then such party immediately may terminate this Agreement with respect to such Product.
