2.Except as expressly amended hereby, the Agreement remains unmodified and in full force and effect as originally executed without waiver of any provision thereof.

4.This Amendment, and all claims or causes of action (whether in contract or tort) that may be based upon, arise out of or relate to this Amendment or the negotiation, execution or performance of this Amendment (including any claim or cause of action based upon, arising out of or related to any representation or warranty made in or in connection with this Amendment), will be construed in accordance with and governed by the laws of the State of Delaware without regard to principles of conflicts of laws which would result in the application of the law of any other jurisdiction.
