not waive, now or in the future, compliance with any other covenant, term or
condition to be performed or complied with nor do they impair any rights or
remedies of the Lenders or the Agent under the Existing Agreement with
respect to any such violation.  Nothing in this First Amendment shall be
deemed or construed to be a waiver or release of, or a limitation upon, the
Lenders' or the Agents' exercise of any of their respective rights and
remedies under the Existing Agreement and the other Loan Documents, whether
arising as a consequence of any Events of Default which may now exist or
otherwise, and all such rights and remedies are hereby expressly reserved.
