         “(b)        By either the Company or Parent if the consummation of the Offer shall not have occurred on or before October 1, 2003 (as extended by the proviso below, the “Termination Date”); provided, however, that (i) the right to terminate this Agreement under this Section 8.1(b) shall not be available to any party whose failure to fulfill any obligation under this Agreement has been the primary cause of the failure of such consummation to occur on or before such date and (ii) if the consummation of the Offer shall not have occurred on or before October 1, 2003 because of the failure of the condition set forth in paragraph (a) of Exhibit B to be satisfied or waived or because any Governmental Authority has requested that the transactions contemplated hereby not be consummated and Parent and the Company agree to such request, then, at the Company’s or Parent’s election, the Termination Date shall be extended to December 31, 2003;"

               Section 9.   Paragraph (b) of Exhibit B to the Merger Agreement is hereby replaced by the following:

         “(b)     (i) the representations and warranties of the Company contained in the Agreement shall not have been true and correct when made as of the date of the Agreement, except in each case for the failure of any such representation or warranty to be true and correct which would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect and (ii) any such inaccuracy has not been cured; or”

              Section 10.   The items set forth on Exhibit A attached hereto shall be deemed included in each section of the Company Disclosure Schedule, in each case, as of the date of the Merger Agreement.

Without limiting the generality of the foregoing, the parties agree that in the event of a conflict between any provision of the Merger Agreement and this Amendment, the provisions of this Amendment shall control.

         (b)        The parties may execute this Amendment in separate counterparts (no one of which need contain the signatures of all parties), each of which will be an original and all of which together will constitute one and the same instrument. Any party may execute this Amendment by facsimile signature, and the other parties will be entitled to rely on such facsimile signature as conclusive evidence that this Amendment has been duly executed by such party.

         (c)        This Amendment shall be governed by, and construed and interpreted in accordance with, the laws of the State of New York.
