WHEREAS, capitalized terms used herein and not otherwise defined shall have the meanings ascribed to them in the Agreement; and

NOW, THEREFORE, in consideration of the mutual promises and covenants contained herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereby agree as follows:

The representations and warranties of the parties set forth in this Agreement shall survive the Closing but shall terminate and expire fifteen (15) months after the Closing Date; provided, however, the representations and warranties set forth in Section 3.14 of this Agreement shall terminate and expire six (6) years after the Closing Date. With the exception of

Buyer’s pre-closing covenants set forth in Section 5.02(d) which shall survive without limit as to time, the pre-closing covenants of the parties hereto shall terminate and expire upon Closing.”

“Time Limits. Notwithstanding any other provision of this Agreement, no claim with respect to the misrepresentation or inaccuracy of a representation and warranty made by a party or parties shall be valid unless notice of such claim is given to the Indemnifying Party within fifteen (15) months after the Closing Date; provided, however, that no claim with respect to the misrepresentation or inaccuracy of a representation and warranty contained in Section 3.14 of this Agreement shall be valid unless notice of such claim is given to the Indemnifying Party within six (6) years after the Closing Date.”
