(a) An Indemnifying Party (as defined below) shall not have any liability to an Indemnified Party (as defined below) under clause (i) of Section 8.1(a) hereof or clause (i) of Section 8.1(b) hereof, as the case may be, unless the aggregate amount of Losses to such Indemnified Party finally determined to arise thereunder, based upon, attributable to or resulting from the failure of any representation or warranty to be 36 true and correct, exceeds $750,000 (the "BASKET") and, subject to Section 8.2(b) below, and in such event, such Indemnifying Party shall only be required to pay the entire amount of such Losses in excess of the Basket. (b) The aggregate amount that an Indemnified Party shall be entitled to recover pursuant to Section 8.1 for any Loss or Losses shall not exceed $50,000,000. (c) The amount of an Indemnifying Party's liability under this Article 8 to an Indemnified Party for any Loss shall be determined by taking into account any insurance proceeds actually received by such Indemnified Party with respect to such Loss (after deducting reasonable costs and expenses incurred in connection with recovery of such proceeds). (d) Except for claims of fraud or similar claims, the indemnification provided in this Article 8 shall be the sole and exclusive remedy after the Closing Date in the case of the Convertible Notes for any claims for indemnification relating to the subject matter of this Agreement for which indemnification is available; PROVIDED that nothing contained herein shall limit rights or remedies expressly provided for in this Agreement or any other Transaction Document or rights or remedies which, as a matter of applicable law or public policy, cannot be limited or waived. 8.3 GENERAL INDEMNIFICATION PROCEDURES. (a) A Person entitled to make a claim for indemnification under Section 8.1 (an "INDEMNIFIED PARTY") against a party (the "INDEMNIFYING PARTY") required thereunder to indemnify such Indemnified Party not involving a claim or action by a third party shall give written notice of the assertion of such claim covered by such indemnity to the Indemnifying Party, which notice shall set forth in reasonable detail, the amount of such claim and a description of the basis for such claim with reference to the provision of this Agreement or the Transaction Document under which liability is asserted. In the event that any suit, action or proceedings shall be instituted by any third party or that any claim or demand shall be asserted by any third party in respect of which indemnification may be sought under Section 8.1 or 8.2 (a "THIRD-PARTY CLAIM"), the Indemnified Party shall reasonably promptly cause written notice of the assertion of such Third Party Claim of which it has knowledge to be forwarded to the Indemnifying Party. The Indemnifying Party shall have the right, at its sole option and expense, to be represented by counsel of its choice and to defend against, negotiate, settle or otherwise take over control and deal with any Third-Party Claim, and if the Indemnifying Party elects to defend against, negotiate, settle or otherwise take over control and deal with any Third-Party Claim, the Indemnifying Party's choice of counsel must be reasonably satisfactory to the Indemnified Party, and the Indemnifying Party shall within twenty (20) days of such notice (or sooner, if the nature of the Third-Party Claim so requires) notify the Indemnified Party of its intent to do so. If the Indemnifying Party elects not to defend against, negotiate, settle or otherwise take over control and deal with any Third-Party Claim, fails to notify the Indemnified Party of its election as herein provided or contests 37 its obligation to indemnify the Indemnified Party for such Losses under this Agreement, the Indemnified Party may defend against, negotiate, settle or otherwise deal with such Third-Party Claim; PROVIDED, THAT if the Indemnifying Party contests its obligations to indemnify the Indemnified Party, and if it is finally determined that any such Third-Party Claim was not a claim for which indemnification was available under this Article 8, the Indemnified Party shall reimburse the Indemnifying Party for any expenses advanced on its behalf; PROVIDED, FURTHER, that the Indemnified Party shall keep the Indemnifying Party fully informed of the facts of the Third-Party Claim and the progress of the defense thereof. If the Indemnified Party defends any Third-Party Claim, then the Indemnifying Party shall reimburse the Indemnified Party for the reasonable and documented expenses of defending such Third-Party Claim with respect to which it is entitled to be indemnified hereunder upon submission of periodic bills. If the Indemnifying Party shall assume the defense of any Third-Party Claim, the Indemnified Party may participate, at his, her or its own expense, in the defense of such Third-Party Claim; PROVIDED, HOWEVER, that such Indemnified Party shall be entitled to participate in any such defense with separate counsel at the expense of the Indemnifying Party (as provided above) if (i) so requested by the Indemnifying Party to participate or (ii) in the reasonable opinion of counsel to the Indemnified Party, a conflict or potential conflict exists between the Indemnified Party and the Indemnifying Party that would make such separate representation advisable; and PROVIDED, FURTHER, that the Indemnifying Party shall not be required to pay for more than one such counsel for all Indemnified Parties in connection with any Third-Party Claim. The parties hereto agree to cooperate fully with each other in connection with the defense, negotiation or settlement of any such Third-Party Claim. (b) After any final judgment or award shall have been rendered by a court, arbitration board or administrative agency of competent jurisdiction and the expiration of the time in which to appeal therefrom, or a settlement (which is reasonably acceptable to the Indemnifying Party) shall have been consummated, or the Indemnified Party and the Indemnifying Party shall have arrived at a mutually binding agreement with respect to a claim for indemnification under Section 8.1, including any Third-Party Claim, the Indemnified Party shall forward to the Indemnifying Party notice of any sums due and owing by the Indemnifying Party pursuant to this Agreement, with respect to such matter and the Indemnifying Party shall be required to make payment of all sums so due and owing to such Indemnified Party by wire transfer of immediately available funds within ten (10) Business Days after the date of such notice. (c) The failure of the Indemnified Party to give reasonably prompt notice of any Third-Party Claim shall not release, waive or otherwise affect the Indemnifying Party's obligations with respect thereto except to the extent that the Indemnifying Party can demonstrate actual loss and prejudice as a result of such failure. 8.4 TAX TREATMENT OF INDEMNITY PAYMENTS. The parties agree that any indemnity payment made pursuant to this Article 8 (an "INDEMNITY PAYMENT") shall be treated by the parties for all tax purposes as an adjustment to the Notes Purchase Price. 38 9.
