The execution, delivery and effectiveness of this Amendment and the other Amendment Documents shall not, except as expressly provided herein or therein, operate as a waiver of any right, power or remedy of Lenders under the Existing Credit Agreement, the Notes, or any other Loan Document nor constitute a waiver of any provision of the Existing Credit Agreement, the Notes or any other Loan Document.  Without limiting the generality of the foregoing, the Collateral Documents and all of the Collateral described therein do and shall continue to secure the payment of all Obligations of the Loan Parties under the Loan Documents, in each case, as amended by this Amendment.
