(a) Each indemnified party shall, with reasonable promptness after obtaining knowledge thereof, provide any indemnifying party against whom a claim for indemnification is to be made under this Article 9 with written notice of all third party actions, suits, proceedings, claims, demands or assessments that may be subject to the indemnification provisions 19 of this Article 9 (collectively, "Third Party Claims"), including, in reasonable detail, the basis for the claim, the nature of Damages and a good faith estimate of the amount of Damages. (b) Each indemnifying party shall have 15 days after its receipt of the claim notice to notify the indemnified party in writing whether the indemnifying party agrees that the claim is subject to this Article 9 and, if so, whether the indemnifying party elects, jointly with any other indemnifying party notified under Section 9.04-1(a), to undertake, conduct and control, through counsel of its or their choosing (subject to the consent of the indemnified party, such consent not to be withheld unreasonably) and at its or their sole risk and expense, the good faith settlement or defense of the Third Party Claim. (c) If within 15 days after its receipt of the claim notice an indemnifying party notifies the indemnified party that it elects to undertake the good faith settlement or defense of the Third Party Claim, the indemnified party shall cooperate reasonably with the indemnifying party in connection therewith including, without limitation, by making available to the indemnifying party all relevant information material to the defense of the Third Party Claim. The indemnified party shall be entitled to participate in the settlement or defense of the Third Party Claim through counsel chosen by the indemnified party, at its expense, and to approve any proposed settlement that would impose any obligation or duty on the indemnified party, which approval may, in the sole discretion of the indemnified party, be withheld. So long as an indemnifying party is contesting the Third Party Claim in good faith and with reasonable diligence, the indemnified party shall not pay or settle the Third Party Claim. Notwithstanding the foregoing, the indemnified party shall have the right to pay or settle any Third Party Claim at any time, provided that in such event it waives any right to indemnification therefor by the indemnifying party. (d) If an indemnifying party does not provide notice that it elects to undertake the good faith settlement or defense of the Third Party Claim, or if an indemnifying party fails to contest the Third Party Claim or undertake or approve settlement, in good faith and with reasonable diligence, the indemnified party shall thereafter have the right to contest, settle or compromise the Third Party Claim in good faith at its exclusive discretion, at the risk and expense of the indemnifying party, and the indemnifying party will thereby waive any claim, defense or argument that the indemnified party's settlement or defense of such Third Party Claim is in any respect inadequate or unreasonable. (e) A party's failure to give timely notice will not constitute a defense, in part or in whole, to any claim for indemnification by such party, except if, and only to the extent that, such failure results in any material prejudice to the indemnifying party. 9.04-2 Non-Third Party Claims. (a) Each indemnified party shall, with reasonable promptness, deliver to any indemnifying party against whom a claim for indemnification is to be made under this Article 9 written notice of all claims for indemnification under this Article 9, other than Third Party Claims, including, in reasonable detail, the basis for the claim, the nature of Damages and a good faith estimate of the amount of Damages. 20 (b) Each indemnifying party shall have 30 days after its receipt of the claim notice to notify the indemnified party in writing whether the indemnifying party accepts liability for all or any part of the Damages described in the claim notice. If the indemnifying party does not so notify the indemnified party, the indemnifying party shall be deemed to accept liability for all the Damages described in the claim notice. (c) A party's failure to give timely notice will not constitute a defense, in part or in whole, to any claim for indemnification by such party, except if, and only to the extent that, such failure results in any material prejudice to the indemnifying party. 9.05 Right of Offset. At the election of GDSC, any liability of Shareholder under Section 9.02 which has been established by agreement, litigation or in accordance with the procedure set forth in Section 9.04 may be satisfied by offsetting such liability against any Earnout Payment (as defined in the ADC Agreement) payable under the ADC Agreement that is then due or that subsequently becomes due; provided, however, that if Shareholder gives notice to GDSC within 30 days after Shareholder receives a notice of claim under Section 9.04-1(a) or 9.04-2(a) of this Agreement that Shareholder contests its liability for such claim, GDSC may not exercise its right of offset until the procedure described in Section 9.06 of the ADC Agreement has been completed. 9.06 Limitations. Anything to the contrary notwithstanding, an indemnified party shall not be indemnified and held harmless in respect of any Damages which are covered by insurance owned by the indemnified party to the extent that any loss is reduced by such insurance. The right of the GDSC Indemnified Persons to seek indemnification from ADC and/or Shareholder under this Agreement or the ADC Agreement shall terminate the sooner of (a) 38 months from Closing or (b) at such time as the total Damages paid by ADC and/or Shareholder (whether or not paid by offset of amounts owed to ADC or Shareholder) reach a total of $3,500,000.00. 9.07 Rights Not Exclusive. An indemnified party's rights to indemnification under this Article 9 shall be the exclusive remedy for recovery of monetary damages in the event of any breach of any representation, warranty or covenant under this Agreement, but such rights are in addition to, and not in lieu of, any other rights to which the indemnified party may be entitled in equity.
