A.                              Promptly, or in any event within ten (10) calendar days (in the case of service of legal process) or within thirty (30) calendar days (in the case of any other claim), following receipt by any party to be indemnified under the provisions of this ARTICLE VIII (the “Indemnitee”) of notice of any action, suit, proceeding, claim, demand or assessment (each, an “Action”) against the Indemnitee that might give rise to a claim pursuant to Section 8.01, Section 8.02 or Section 8.03, the Indemnitee shall give written notice thereof to the party or parties obligated to provide such indemnification under the provisions of this ARTICLE VIII (collectively, the “Indemnitor”) indicating the nature of such claim, the basis therefor and the estimated amount thereof. Failure to give any notice provided hereunder shall in no way be deemed a forfeiture of any

14

Indemnitee’s rights to be indemnified hereunder; provided, however, if the Indemnitor shall have been prejudiced in any material respect by such failure so to notify the Indemnitor, the Indemnitor shall have the right to set off against any amounts payable or that become payable by the Indemnitor under this Agreement the amount by which the Indemnitor has been damaged as a result of the failure so to notify the Indemnitor. A claim for indemnity may, at the option of the Indemnitee, be asserted as soon as any claim has been asserted by a third party in writing, regardless of whether actual harm has been suffered or out-of-pocket expenses incurred.

B.                                At any time after the Indemnitee gives notice to the Indemnitor of a claim being made against the Indemnitee for which a claim for indemnity is being asserted, to the extent that such claim is not being defended by any third party under the terms of any applicable insurance policy or policies, the Indemnitee shall permit the Indemnitor, at the option and expense of the Indemnitor, to assume the complete defense of such Action with full authority to conduct such defense and to settle or otherwise dispose of the same (except as hereinafter provided), and the Indemnitee will reasonably cooperate in such defense. In order to assume such defense, Indemnitor must notify Indemnitee in writing of its election to do so within ten (10) calendar days following receipt of notice of the claim from Indemnitee; in the event that Indemnitor does not so notify Indemnitee within such ten (10) calendar day period, Indemnitor shall be deemed to have elected not to assume such defense. After notice to the Indemnitee of the Indemnitor’s election to assume the defense of such Action as provided above, the Indemnitor shall be liable to the Indemnitee for such legal or other expenses subsequently incurred at the request of the Indemnitor by the Indemnitee in connection with the defense thereof.

C.                                The Indemnitor will not, in defense of any such Action, except with the consent of the Indemnitee, consent to the entry of any judgment or enter into any settlement that does not include, as an unconditional term thereof, the release by claimant or plaintiff of Indemnitee from all claims and/or liability in respect thereof

D.                               As to those Actions with respect to which the Indemnitor does not elect to assume control of the defense, (i) the Indemnitee will afford the Indemnitor an opportunity to participate in such defense, at the Indemnitor’s own cost and expense; (ii) the Indemnitee will not settle or otherwise dispose of any of the same without the consent of the Indemnitor, which consent will not be unreasonably withheld; and (iii) the Indemnitor agrees to reasonably cooperate in such defense.

E.                                 The Indemnitor shall make payments to the Indemnitee, pursuant to the provisions hereof, with respect to Actions of third parties as follows: with respect to out-of-pocket expenses of the Indemnitee, on demand as incurred, and, with respect to amounts and fees owed to third parties, to the extent not paid directly to such third parties by the Indemnitor, on demand at the time of payment by the Indemnitee to such third party.

F.                                 The liability of the Indemnitor hereunder shall be subject to the following limitations:

15

(i)                                Subject to the provisions of 8.04E with respect to out-of-pocket expenses of Indemnitee, the Indemnitor shall pay claims hereunder when a claim against the Indemnitee or its Insiders has been established by a final judgment in litigation with a third party in which the Indemnitor has assumed the defense, or by a settlement with a third party consented to in writing by the Indemnitee; payment of other claims as to which the Indemnitee may contest its liability, or claims not involving third parties, shall be made when the dispute is settled either by litigation or consent;

(ii)                             payments for amounts due the Indemnitee or its Insiders hereunder shall be paid by either cash or cashier’s check; and

(iii)                          the Indemnitor shall not be liable for any claims covered by the indemnities under Section 8.01, Section 8.02 and Section 8.03 unless the Indemnitor has been notified of such claims pursuant to Section 8.04 within a period four (4) years from the Closing Date; provided, however, this provision shall not apply to claims under Section 4.01, Section 4.06, Section 4.09, Section 4.14 and Section 4.15 as to which notice may be given at any time.
