(b) If any Proceeding referred to in Section 11.7(a) is brought against an Indemnitee and it gives notice to the Indemnitor of the commencement of such Proceeding, the Indemnitor will be entitled to participate in such Proceeding and, to the extent that it wishes (unless (i) the Indemnitor is also a party to such Proceeding and the Indemnitee determines in good faith that joint representation would be inappropriate, or (ii) the Indemnitor fails to provide reasonable assurance to the Indemnitee of its financial capacity to defend such Proceeding and provide indemnification with respect to such Proceeding), to assume the defense of such Proceeding with counsel satisfactory to the Indemnitee and, after notice from the Indemnitor to the Indemnitee of its election to assume the defense of such Proceeding, the Indemnitor will not, as long as it diligently conducts such defense, be liable to the Indemnitee under this Section 11.7 for any fees of other counsel with respect to the defense of such Proceeding or other expenses, incurred by the Indemnitee in connection with the defense of such Proceeding. If the Indemnitor assumes the defense of a Proceeding, no compromise or settlement of such claims may be effected by the Indemnitor without the Indemnitee's Consent unless (i) there is no finding or admission of any violation of Legal Requirements or any violation of the rights of any Person and no effect on any other claims that may be made against the Indemnitee, and (ii) the sole relief provided is monetary damages that are paid in full by the Indemnitor; and (iii) the Indemnitor will have no Liability with respect to any compromise or settlement of such claims effected without its Consent. (c) Notwithstanding the foregoing, if an Indemnitee determines in good faith that there is a reasonable probability that a Proceeding may adversely affect it other than as a result of monetary damages for which it would be entitled to indemnification under this Agreement, the Indemnitee may, by notice to the Indemnitor, assume the exclusive right to defend, compromise, or settle such Proceeding, but the Indemnitor will not be bound by any determination of a Proceeding so defended for the purposes of this Agreement or any compromise or settlement effected without its Consent (which may not be unreasonably withheld). (d) Notwithstanding the provisions of Section 13.4, Buyer, Sellers and each Shareholder hereby consent as between themselves to the non-exclusive jurisdiction of any court in which a Proceeding is brought against any Indemnified Person for purposes of any claim that an Indemnified Person may have under this Agreement with respect to such Proceeding or the matters alleged therein, and agree that process may be served on Buyer, Sellers and the Shareholder with respect to such a claim anywhere in the world. (e) With respect to any Proceeding subject to indemnification under this Section 11.7(i) both the Indemnitee and the Indemnitor, as the case may be, shall keep the other party fully informed of the Proceeding at all stages thereof where such party is not represented by its own counsel, and (ii) the Parties agree (each at its own expense) to render to each other such assistance as they may reasonably require of each other and to 41 cooperate in good faith with each other in order to ensure the proper and adequate defense of any Proceeding brought by any third party. (f) To the extent permitted by law, with respect to any Proceeding subject to indemnification under this Section 11.7, the Parties agree to cooperate in such a manner as to preserve in full (to the extent possible) the confidentiality of all confidential business Records and the attorney-client and work-product privileges. In connection therewith, each Party agrees that: (1) it will use its Best Efforts, in any Proceeding in which it has assumed or participated in the defense, to avoid production of confidential business Records (consistent with applicable law and rules of procedure) without a protective order in place, and (ii) all communications between any Party hereto and counsel responsible for or participating in the defense of any Proceeding shall, to the extent possible, be made so as to preserve any applicable attorney-client or work-product privilege. 11.7 PROCEDURE FOR INDEMNIFICATION OTHER CLAIMS A claim for indemnification for any matter not involving a third-party claim may be asserted by notice to the Party from whom indemnification is sought. 12. CONFIDENTIALITY Between the date of this Agreement and the Closing Date, Buyer, Sellers and the Shareholders will maintain in reasonable confidence, and will reasonably cause the directors, officers, employees, agents, and advisors of Buyer and the Sellers to maintain in confidence, and not use to the detriment of another Party any written, oral, or other information obtained in confidence from another Party or Sellers in connection with this Agreement or the Contemplated Transactions, unless (a) such information is already known to such Party or to others not bound by a duty of confidentiality or such information becomes publicly available through no fault of such Party, (b) the use of such information is necessary or appropriate in making any filing or obtaining any consent or approval required for the consummation of the Contemplated Transactions, or (c) the famishing or use of such information is required by any Proceedings. If the Contemplated Transactions are not consummated, each Party will return or destroy within ten (10) days as much of such written information as the other Party may reasonably request. Unless consented to by each Party in advance or required by Legal Requirements, prior to the Closing, each Party shall keep this Agreement strictly confidential and may not make any disclosure of this Agreement to any Person. 42 13.
