This indemnity provision shall survive Closing for a period of one (1) year.

10.2Sellers' Right to Indemnification. Buyer undertakes and agrees to hold Sellers harmless against any and all losses, costs, liabilities, claims, obligations and expenses, including reasonable attorneys' fees incurred or suffered by Sellers arising from the breach, misrepresentation or other violation of any covenants, warranty or representation by Buyer contained in this Agreement. This indemnity provision shall survive Closing for a period of one (1) year.

10.3 Procedure. If any claim or proceeding covered by the foregoing agreements to indemnify and hold harmless shall arise, the party who seeks indemnification (the "Indemnified Party") shall given written notice thereof to the other party (the "Indemnitor") promptly (but in no event more than ten (10) days) after it learns of the existence of such claim or proceeding. Any claim for indemnification hereunder shall be accompanied by evidence demonstrating the Indemnified Party's right or possible right to indemnification, including a copy of all supporting documents relevant thereto. The Indemnitor shall have the right to employ counsel reasonably acceptable to the Indemnified Party to defend against any such claim or proceeding, or to compromise, settle or otherwise dispose of the same; provided, however, that no settlement or compromise shall be effected without the consent of the Indemnified Party, which consent shall not be unreasonably withheld, and providedfurther that in the event the Indemnified Party does not consent to a bonafide offer of settlement made by a third party and the settlement involves only the payment of money, then the Indemnitor may, in lieu of payment of such settlement to such third party, pay such amount to the Indemnified Party. After the payment to the Indemnified Party, the Indemnitor shall have no further liability with respect to such claim or proceeding and the Indemnified Party shall assume full responsibility to defend the same. After notice from the Indemnitor to the Indemnified Party of its election to assume the defense of such claim or proceeding, the Indemnitor shall not be liable to the Indemnified Party under this paragraph for any legal or other expenses subsequently incurred by the Indemnified Party in connection with the defense thereof; provided, however, that the Indemnified Party shall have the right to employ counsel to represent it if, in the Indemnified Party's reasonable judgment, it is advisable for the Indemnified Party to be represented by separate counsel, and in that event the fees and expenses of such separate counsel shall be paid by the Indemnified Party. The parties will fully cooperate in any such action, making available to each other books or records for the defense of any such claim or proceeding. If the Indemnitor fails to acknowledge in writing its obligation to defend against or settle such claim or proceeding within ten (10) days after receiving notice of the claim or proceeding from the Indemnified Party (or such shorter time specified in the notice as the circumstances of the matter may dictate), the Indemnified Party shall be free to dispose of the matter, at the expense of the Indemnitor (but subject to the Indemnitor's right subsequently to contest through appropriate proceedings its obligation to provide indemnification), in any way which the Indemnified Party deems in its best interest.

10.4 Limitations on Indemnification Rights. Indemnification shall be due only to the extent of the loss or damage actually suffered (i.e., reduced by any offsetting or related asset or service received and by any recovery from any third party, such as an insurer), net after the amount equal to any reduction in federal, state or local income, franchise or other taxes occasioned by such loss or damage (even though the tax return by which such reduction would have been realized is not yet due), but including an amount equal to any increase in federal, state and local income, franchise or other taxes occasioned by the indemnification payment and then only to the extent of the excess over the Agreed De Minimis Amount (hereinafter defined). The Indemnitor shall be subrogated to all rights of the Indemnified Party against any third party with respect to any claim for which indemnification is paid. Notwithstanding the foregoing, (i) the Indemnitor shall not be liable to the Indemnified Party for any individual misrepresentation, breach of warranty or violation of covenant where the otherwise indemnifiable amount does not exceed $5,000 and, as regards all such indemnifiable misrepresentations or breaches of warranty that do not exceed $5,000, the Indemnitor shall not be liable except to the extent that the aggregate amount thereof exceeds $5,000 (such sum being herein referred to as the "Agreed De Minimis Amount") and (ii) in the event that Sellers are the Indemnitor, Sellers' liability to pay in respect of the indemnification obligations shall not exceed the cumulative total amount of Five Hundred Thousand Dollars ($500,000).
