          This letter amendment agreement shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to conflicts of laws principles which could cause the laws of another jurisdiction to apply. The parties acknowledge that any statements or representations that may have been made heretofore regarding the terms and matters dealt with in this letter amendment agreement are void and have no effect and that neither party has relied thereon.
