The Purchaser hereby indemnifies and holds harmless, for a period of eighteen (18) months from the date hereof, the Company, its officers, directors, agents, attorneys and affiliates, and their respective successors and assigns from and against any loss, damage, or expense (including reasonable attorneys' fees) caused by or arising out of: -17- (a) any breach of any representation or warranty made by the Purchaser herein, in any Exhibit hereto, or in any certificate or other instrument delivered by the Purchaser pursuant hereto; or (b) any liability arising out of any and all actions, suits, proceedings, claims, demands, judgments, costs and expenses (including reasonable legal and accounting fees) incident to the foregoing. 16.3 CONDITIONS OF INDEMNIFICATION. The respective obligations and liabilities of the Company and the Purchaser to the other under Sections 16.1 and 16.2 hereof with respect to claims resulting from the assertion of liability by third parties shall be subject to the following terms and conditions: (a) within 10 days (or such earlier time as might be required to avoid prejudicing the indemnifying party's position) after receipt of notice of commencement of any action evidenced by service of process or other legal pleading, or with reasonable promptness after the assertion in writing of any claim by a third party, the party to be indemnified shall give the indemnifying party written notice thereof together with a copy of such claim, process, or other legal pleading, and the indemnifying party shall have the right to undertake the defense thereof by representatives of its own choosing and at its own expense; provided, however, that the party to be indemnified may participate in the defense with counsel of its own choice and at its own expense. (b) in the event that the indemnifying party, by the 30th day after receipt of notice of any such claim (or, if earlier, by the 10th day preceding the day on which an answer or other pleading must be served in order to prevent judgment by default in favor of the person asserting such claim), does not elect to defend against such claim, the party to be indemnified will (upon further notice to the indemnifying party) have the right to undertake the defense, compromise or settlement of such claim on behalf of and for the account and risk of the indemnifying party and at the indemnifying party's expense, subject to the right of other indemnifying party to assume the defense of such claims at any time prior to settlement, compromise or final determination thereof. (c) anything in this Section 16.3 to the contrary notwithstanding, the indemnifying party shall not settle any claim without the consent of the party to be indemnified unless such settlement involves only the payment of money and the claimant provides to the party to be indemnified a release from all liability in respect of such claim. If the settlement of the claim involves more than the payment of money, the indemnifying party shall not settle the claim without the prior consent of the party to be indemnified, which consent shall not be unreasonably withheld. (d) the party to be indemnified and the indemnifying party will each cooperate with all reasonable requests of the other. 17. ENTIRE AGREEMENT.
