All Transactional Warranties and all warranties in Article 4 hereof shall survive for the applicable statute of limitations. 15.6 Sole and Exclusive Remedy. ------------------------- Except as set forth in this Section and Section 2.3(d), the parties acknowledge and agree that the indemnification provided under this Article 15 shall be the sole and exclusive remedy of the parties with respect to the breach of any covenant, representation or warranty contained herein.

and quantifiable), and the basis thereof, provided that the failure to promptly give notification shall not constitute a defense to a claim except to the extent the Indemnitor can show that it was materially prejudiced by the delay in notification. The obligations and liabilities of the Indemnitor with respect to claims resulting from the assertion of liability by any third party shall be subject to the following terms and conditions: (a) In the event any action, suit or proceeding is brought against the Indemnitee, with respect to which the Indemnitor may have liability under the indemnity provisions contained herein, the action, suit or proceeding shall be defended (including all proceedings on appeal or for review which counsel for the Indemnitee shall deem appropriate) by the Indemnitor at its expense. The Indemnitee shall have the right to employ its own counsel in any such case, but the fees and expenses of such counsel shall be at the Indemnitee's own expenses unless (i) the Indemnitor has failed or refused to perform its obligations under the preceding sentence or (ii) the Indemnitor's defense would result in a conflict of interest under which it would not be appropriate for counsel for the Indemnitor to represent the Indemnitee, or (iii) unless the employment of such counsel and the payment of such fees and expenses both shall have been specifically authorized by the Indemnitor in connection with the defense of such action, suit or proceeding. In any such case only that portion of such fees and expenses reasonably related to matters covered by the indemnity agreements contained herein shall be borne by the Indemnitor. The Indemnitee shall be kept fully informed of such action, suit or proceeding at all stages thereof whether or not it is so represented. The Indemnitee shall make available to the Indemnitor and its attorneys and accountants all books and records of the Indemnitee relating to such proceedings or litigation and the parties hereto agree to render to -58-

each other such assistance as they may reasonably require of each other in order to ensure the proper and adequate defense of any such action, suit or proceeding. (b) The Indemnitee shall not make any settlement of any claims without the written consent of the Indemnitor. The Indemnitor shall have the right at its own expense to settle any claim on such terms and conditions as the Indemnitor may deem acceptable, provided that the settlement does not impose any legal obligations upon the Indemnitee. (c) Should Seller's Representative and/or Heller notify Buyer that any claim in respect of which the Sellers and/or Heller are the Indemnitor is covered in whole or in part by an occurrence policy of insurance (or a claims-made policy of insurance which has been converted to an occurrence policy through the purchase of so-called tail coverage or any other similar arrangement) which was in effect on or prior to the Closing Date, Buyer shall cause the Companies to reasonably cooperate with Sellers and Heller (including, without limitation, by the filing and pursuit of lawful claims upon insurers). Any amounts actually received by the Companies shall either (at Sellers' and Heller's election) be retained by the Company and applied to reduce the Sellers' and Heller's indemnification obligations or be paid to the Sellers and Heller. If in respect of any claim the Buyer or the Companies shall have any right of recourse to a third party, the Sellers and Heller shall be subrogated to all such rights. -59-
