With respect to each claim made by a third party for which an Indemnified Party (as hereinafter defined) seeks indemnification under this Article 5 (a "Third Party Claim"), the Indemnified Party shall give prompt notice to the Indemnifying Party (as hereinafter defined) of the Third Party Claim, provided that failure to give such notice promptly shall not relieve or limit the obligations of the Indemnifying Party except to the extent the Indemnifying Party has been materially prejudiced thereby (and such failure to notify the Indemnifying Party will not relieve the Indemnifying Party from any other liability it may have to the Indemnified Party). The Indemnifying Party will have the right to defend the Indemnified Party against any Third Party Claim with counsel of the Indemnifying Party's choice reasonably satisfactory to the Indemnified Party so long as and to the extent that (a) the Indemnifying Party notifies the Indemnified Party in writing, within fifteen (15) days after receipt from the Indemnified Party of notice of the claim, that the Indemnifying Party will indemnify and defend the Indemnified Party and agrees in writing to provide such defense and indemnification, from and against any Indemnifiable Damages with respect to which such Indemnified Party is entitled to indemnification and defense under Section 5.01 hereof that the Indemnified Party may suffer resulting from, arising out of, relating to, in the nature of, or caused by the claim; (b) the claim seeks the recovery of solely money damages and does not contain a claim for an injunction, specific performance, a declaration of rights or other equitable relief; (c) the Indemnifying Party conducts the defense of the claim actively and diligently; and (d) representation of both the Indemnified Party and the Indemnifying Party by the counsel selected by the Indemnifying Party would not create an actual or potential conflict of interest between the Indemnified Party and the Indemnifying Party. In all other cases, the Indemnified Party shall be entitled to retain its own separate counsel and control the defense of the Third Party Claim, all at the sole cost and expense of the Indemnifying Party. If there is a conflict of interest, however, that would prevent counsel for the Indemnifying Party from also representing the Indemnified Party as reasonably determined by the Indemnified Party, then the Indemnified Party shall have the right to select separate counsel, at the Indemnifying Party's sole cost and expense, to participate in the defense of such action on behalf of the Indemnified Party. After notice from the Indemnifying Party to the Indemnified Party of its election to so assume the defense thereof, the Indemnifying Party will not be liable to the Indemnified Party pursuant to the provisions of this Article 5 for the related counsel and paralegal fees and expenses subsequently incurred by the Indemnified Party in connection with the defense thereof, unless (i) the Indemnified Party shall have employed counsel in accordance with the provisions of this paragraph, (ii) the Indemnifying Party shall not have employed counsel reasonably satisfactory to the Indemnified Party to represent the Indemnified Party within a reasonable time after notice of the commencement of the action, or (iii) the Indemnifying Party has not authorized the employment of counsel for the Indemnified Party at the expense of the Indemnifying Party. Notwithstanding anything to the contrary in this Agreement, the Indemnifying Party shall have no right to settle or compromise, without the prior written consent of the Indemnified Party, any action or claim to the extent the settlement or compromise provides for any injunctive or other equitable relief against the Indemnified Party other than monetary damages, or does not include as an unconditional term thereof the providing to the Indemnified Party by the third party of a release, in form and substance acceptable to the Indemnified Party, of all liability in respect of such claim. Nothing stated herein shall otherwise affect the Indemnifying Party's obligation to pay the Indemnified Party any Indemnifiable Damages pursuant to the provisions of this Article 5. The Indemnified Party shall reasonably cooperate with the Indemnifying Party in the defense of any action or claim assumed by the Indemnifying Party in accordance with the terms hereof and shall make available to the Indemnifying Party such information as the Indemnifying Party reasonably requests in connection with any such defense. For purposes of this Article 5, an "Indemnified Party" shall mean a party claiming defense or indemnification under this Article 5 and an "Indemnifying Party" shall mean a party from whom defense or indemnification is sought under this Article 5. With regard to any Third Party Claims for which indemnification is payable hereunder, such indemnification shall be paid by the Indemnifying Party upon the earliest to occur of:

- 12 -

(a) the entry of a judgment against the Indemnified Party and the expiration of any applicable appeal period, or if earlier, ten (10) days prior to the date that the judgment creditor has the right to execute the judgment; (b) the entry of a non-appealable judgment or final appellate decision against the Indemnified Party; (c) a settlement of the claim; or (d) with respect to indemnities for tax liabilities, upon the issuance of any binding resolution by a taxation authority. Notwithstanding the foregoing, expenses of counsel to the Indemnified Party shall be reimbursed on a solicitor-client basis by the Indemnifying Party. All indemnification claims not paid when due shall bear interest at a rate equal to the lesser of 10% per annum or the highest rate permitted by law.

The right to indemnification, payment of Indemnifiable Damages or other remedy based upon breach of representations, warranties, covenants, agreements or obligations or otherwise will not be affected by any investigation conducted (or not conducted) with respect to, or knowledge acquired (or capable of being acquired) at any time, whether before or after the execution and delivery of this Agreement or the Closing Date, with respect to the accuracy or inaccuracy of or compliance with any such representation, warranty, covenant, agreement or obligation. The waiver of any condition based on the accuracy of any representation or warranty, or on the performance of or compliance with any covenant, agreement or obligation, will not affect the right to indemnification, payment of Indemnifiable Damages or other remedy based on such representations, warranties, covenants, agreements and obligations.

Section 5.05 Notwithstanding anything in this Article 5 to the contrary, Seller and Buyer shall not be entitled to indemnification with respect to a breach of any representation or warranty unless the amount of such claim or claims, in the aggregate, exceed one hundred thousand dollars ($100,000) (each, a "Permitted Claim") and neither Party shall be entitled to indemnification or damages for any amount in excess of three million six hundred fifty thousand dollars ($3,650,000).
