For purposes of this provision, a "final adjudicated determination" shall mean a determination by the highest court of competent jurisdiction to which the Shareholder could appeal, or the determination of a lower court or the Internal Revenue Service, as the case may be, if the Shareholder has not filed a suit in a court of appropriate jurisdiction before the expiration of the applicable statute of limitations or the date for filing an appeal of an adverse decision has expired. 8.2. Indemnification by Key. Key shall indemnify, defend and hold harmless the Shareholder and its officers, directors, employees and agents against and with respect to any and all Damages that such indemnitees shall incur or suffer, which arise, result from or relate to (i) any breach of, or failure by WellTech or Key to perform any of their representations, warranties, covenants or agreements in this Agreement or in any schedule, certificate, exhibit or other instrument furnished or delivered to Brooks or the Shareholder by or on behalf of Key or WellTech under this Agreement and (ii) any obligation of the Shareholder or its consolidated group of corporations to contribute to the payment of any taxes determined on a consolidated, combined or unitary basis with respect to a group of corporations that includes or included the Surviving Corporation or the business of Brooks allocable to any period on or after the Effective Date. In addition, Key will indemnify, defend and hold harmless the Shareholder and its officers, directors, employees and agents against any claims to which the Shareholder may become subject under the Securities Act or otherwise, insofar as such claims (or actions or proceedings whether commenced or threatened, in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, any preliminary prospectus, final prospectus or summary prospectus contained therein, or any amendment or supplement thereto, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and Key will reimburse the Shareholder and each such controlling person for any legal or any other expenses reasonably incurred by them in connection with investigating or defending any such claim (or action or proceeding in respect thereof); provided that Key shall not be liable in any such case to the extent that a claim (or action or proceeding in respect thereof) arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in such Registration Statement, any such preliminary prospectus, final prospectus, summary prospectus, amendment or supplement in reliance upon and in conformity ::ODMA\PCDOCS\DOCS\97107\2 36 with written information furnished to Key, in an instrument duly executed by the President or Senior Vice President of Finance of Shareholder specifically stating that it is for use in the preparation thereof. 8.3. Indemnification Procedure. If any party hereto discovers or otherwise becomes aware of an indemnification claim arising under Section 8.1 or Section 8.2 of this Agreement, such indemnified party shall give written notice to the indemnifying party, specifying such claim, and may thereafter exercise any remedies available to such party under this Agreement; , that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of any obligations hereunder, to the extent the indemnifying party is not materially prejudiced thereby. Further, promptly after receipt by an indemnified party hereunder of written notice of the commencement of any action or proceeding with respect to which a claim for indemnification may be made pursuant to this Article 8, such indemnified party shall, if a claim in respect thereof is to be made against any indemnifying party, give written notice to the latter of the commencement of such action; provided, that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of any obligations hereunder, to the extent the indemnifying party is not materially prejudiced thereby. In case any such action is brought against an indemnified party, the indemnifying party shall be entitled to participate in and to assume the defense thereof, jointly with any other indemnifying party similarly notified, to the extent that it may wish, with counsel reasonably satisfactory to such indemnified party, and after such notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party for any legal fees and expenses subsequently incurred by the latter in connection with the defense thereof unless the indemnifying party has failed to assume the defense of such claim and to employ counsel reasonably satisfactory to such indemnified person. An indemnifying party who elects not to assume the defense of a claim shall not be liable for the fees and expenses of more than one counsel in any single jurisdiction for all parties indemnified by such indemnifying party with respect to such claim or with respect to claims separate but similar or related in the same jurisdiction arising out of the same general allegations. Notwith standing any of the foregoing to the contrary, the indemnified party will be entitled to select its own counsel and assume the defense of any action brought against it if the indemnifying party fails to select counsel reasonably satisfactory to the indemnified party, the expenses of such defense to be paid by the indemnifying party. No indemnifying party shall consent to entry of any judgment or enter into any settlement with respect to a claim without the consent of the indemnified party, which consent shall not be unreasonably withheld, or unless such judgment or settlement includes as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability with respect to such claim. No indemnified party shall consent to entry of any judgment or enter into any settlement of any such action, the defense of which has been assumed by an indemnifying party, without the consent of such indemnifying party, which consent shall not be unreasonably withheld. 8.4. Limitation on Damages. Notwithstanding anything in this Agreement to the contrary, the Shareholder shall not be liable to Key and the Surviving Corporation or any of their respective officers, directors, employees, agents or stockholders, their successors or assigns, for any Damages suffered or incurred by Key or the Surviving Corporation in excess of the Liability Exception (hereinafter defined); provided, however, that to the extent there are Damages suffered or incurred ::ODMA\PCDOCS\DOCS\97107\2 37 by Key or the Surviving Corporation arising out of, or attributable to, a single occurrence or event that are equal to the Liability Exception, then, in such event, Key or WellTech shall be entitled to indemnification by the Shareholder for the total amount of such Damages. The aggregate amount of any Damages owed by the Shareholder to Key or WellTech shall not exceed the value of the shares received by Shareholder under Section 1.11.2.1, which for this purpose shall be the number of Key Shares received multiplied by the Average Closing Price. 8.5. Liability Exception. For purposes of this Section, the term "Liability Exception" shall mean $250,000; provided however, that the Liability Exception shall not include Damages pursuant to Section 2.1.11 relating to Taxes. 8.6. Exclusive Remedy. From and after the Effective Date, the indemnification provided in Sections 8.1 and 8.2 shall be the exclusive remedy that may be asserted under this Agreement or in connection with the transactions contemplated herein. Notwithstanding any provision to the contrary contained herein, each of the parties to this Agreement hereby waives any right to recover special, punitive or exemplary damages for any claim asserted against the other. ARTICLE 9 MISCELLANEOUS 9.1. Survival of Representations, Warranties and Covenants. All representations and warranties made by the parties hereto shall survive for a period of 24 months from the Effective Date, notwithstanding any investigation made by or on behalf of any of the parties hereto; provided, however, that the representations and warranties contained in Section 2.1.11, 3.3 and 4.3.6 hereof shall survive until the expiration of the applicable statute of limitations associated with the taxes at issue.
