In calculating the amount of any Losses of an Indemnified Party hereunder, there shall be subtracted the amount of any insurance proceeds and third-party payments received by the Indemnified Party with respect to such Losses, if any.

Section 4.2 Notice of Claims; Procedures. If an Indemnified Party makes any claim against an Indemnifying Party for indemnification, the claim shall be in writing and shall state in general terms the facts upon which such Indemnified Party makes the claim. In the event of any claim or demand asserted against an Indemnified Party by a third party upon which the

Indemnified Party may claim indemnification, the Indemnifying Party shall give written notice to the Indemnified Party within 30 days after receipt from the Indemnified Party of the claim referred to above, indicating whether such Indemnifying Party intends to assume the defense of the claim or demand. If an Indemnifying Party assumes the defense, such Indemnifying Party shall have the right to fully control and settle the proceeding, provided, that, any such settlement or compromise shall be permitted hereunder only with the written consent of the Indemnified Party. If the Indemnifying Party elects not to assume the defense, fails to make such an election within the 30-day period or fails to actively and diligently conduct the defense, the Indemnified Party may, at its option, defend, settle, compromise or pay such action or claim at the expense of the Indemnifying Party; provided, that, any such settlement or compromise shall be permitted hereunder only with the written consent of the Indemnifying Party, which consent shall not be unreasonably withheld or delayed.

Section 4.3 Cap. Notwithstanding the foregoing, the Indemnifying Party shall have no liability (for indemnification or otherwise) with respect to any Losses in excess of the Purchase Price.

Section 4.4 Third Party Claims.

(a) If any third party shall notify any Indemnified Party in writing with respect to any matter involving a claim by such third party (a “Third Party Claim”) which such Indemnified Party believes would give rise to a claim for indemnification against the Indemnifying Party under this Article IV, then the Indemnified Party shall promptly (i) notify the Indemnifying Party thereof in writing within thirty (30) days of receipt of notice of such claim and (ii) transmit to the Indemnifying Party a written notice (“Claim Notice”) describing in reasonable detail the nature of the Third Party Claim, a copy of all papers served with respect to such claim (if any), and the basis of the Indemnified Party’s request for indemnification under this Agreement.

(b) Subject to Section 4.4(d) below, upon receipt of a Claim Notice with respect to a Third Party Claim, the Indemnifying Party shall have the right to assume the defense of any Third Party Claim by notifying the Indemnified Party in writing that the Indemnifying Party elects to assume the defense of such Third Party Claim, and upon delivery of such notice by the Indemnifying Party, the Indemnifying Party shall have the right to defend such Third Party Claim with counsel, selected by it, who is reasonably satisfactory to the Indemnified Party, by all appropriate proceedings, which proceedings shall be prosecuted actively and diligently by the Indemnifying Party to a final conclusion or settled. Notwithstanding the foregoing, the Indemnifying Party shall not be entitled to consent to the entry of a judgment or enter into any compromise or settlement with respect to such Third Party Claim without the prior written consent of the Indemnified Party (which shall not be unreasonably withheld).

(c) If requested by the Indemnifying Party, the Indemnified Party agrees, at the sole cost and expense of the Indemnifying Party, to cooperate with the Indemnifying Party and its counsel in contesting any Third Party Claim which the Indemnifying Party elects to contest, including the making of any related counterclaim against the person asserting the Third Party Claim or any cross complaint against any person. The Indemnified Party shall have the right to receive copies of all pleadings, notices and communications with respect to any Third Party Claim, other than any privileged communications between the Indemnifying Party and its counsel, and shall be entitled, at its sole cost and expense, to retain separate co-counsel and participate in, but not control, any defense or settlement of any Third Party Claim assumed by the Indemnifying Party pursuant to Section 4.4(b); provided, however, if, based on written advice of counsel, the

Indemnified Party concludes that there is a reasonable likelihood of a conflict of interest between the Indemnifying Party and the Indemnified Party with respect to such Third Party Claim, the Indemnifying Party shall bear the reasonable costs and expenses of counsel retained by the Indemnified Party in connection with such defense.

(d) If (i) the Indemnifying Party fails to notify the Indemnified Party within the thirty (30) days after receipt of any Claim Notice that the Indemnifying Party elects to assume the defense of any Third Party Claim pursuant to Section 4.4(b), (ii) the Indemnifying Party elects to assume the defense of any Third Party Claim pursuant to Section 4.4(b) but fails to diligently prosecute or settle such Third Party Claim, (iii) the Indemnifying Party and the Indemnified Party are parties to the same proceeding (or, assuming the veracity of the facts alleged by the party bringing the Third Party Claim, the Indemnifying Party and the Indemnified Party may become parties to the same proceeding) and the Indemnified Party determines in good faith that a conflict of interest exists between the Indemnifying Party and the Indemnified Party, (iv) the Indemnified Party determines in good faith that there is a reasonable possibility that it will be prejudiced in any material respect beyond the ambit of such Third Party Claim by the Indemnifying Party’s control of the defense and proceedings with respect to any Third Party Claim, or (v) such Third Party Claim is a claim by a governmental tax authority, then (A) the Indemnified Party shall have the right to assume full control of the defense and proceedings with respect to such Third Party Claim, and the Indemnified Party may compromise or settle such Third Party Claim without consulting with, or obtaining consent from, the Indemnifying Party in connection therewith (it being understood and agreed that the Indemnifying Party shall not be bound by any such compromise or settlement entered into without its consent) and (B) the Indemnifying Party shall reimburse the Indemnified Party promptly and periodically for the costs of defending against the Third Party Claim (including fees and disbursements of no more than one counsel per jurisdiction (such counsel reasonably acceptable to the Indemnifying Party) reasonably incurred in connection with such Third Party Claim). The Indemnified Party shall have full control of such defense and proceedings, although the Indemnifying Party shall be entitled to participate in any defense or settlement controlled by the Indemnified Party pursuant to this Section 4.4(d) at its sole expense. Any compromise or settlement of a Third Party Claim effected by the Indemnified Party without the Indemnifying Party’s consent shall not be dispositive of the amount of any Losses with respect to such Third Party Claim.

(e) In the event any Indemnified Party should have a claim against the Indemnifying Party hereunder which does not involve a Third Party Claim, the Indemnified Party shall promptly transmit to the Indemnifying Party a written notice (the “Indemnity Notice”) describing in reasonable detail the nature of the claim, the Indemnified Party’s best estimate of the amount of Losses attributable to such claim and the basis of the Indemnified Party’s request for indemnification under this Agreement; provided that no delay on the part of the Indemnified Party in delivering the Indemnity Notice pursuant to this Section 4.4(e) shall relieve the Indemnifying Party of any obligation hereunder unless (and then solely to the extent) the Indemnifying Party is prejudiced thereby. If the Indemnifying Party does not notify the Indemnified Party within thirty (30) days from its receipt of the Indemnity Notice that the Indemnifying Party disputes such claim, the Indemnifying Party shall be deemed to have accepted and agreed with such claim.
