requisite corporate power and authority to execute and deliver this Amendment
and the Consent, as applicable, and to perform its obligations hereunder and
under the Loan Documents (as amended hereby) to which it is a party. The
execution, delivery and performance by the Borrower of this Amendment and by

          SECTION 4. Reference to and Effect on the Loan Documents.

          (a) Upon and after the effectiveness of this Amendment, each reference
in the Credit Agreement to "this Agreement", "hereunder", "hereof" or words of

generality of the foregoing, the Collateral Documents and all of the Collateral
described therein do and shall continue to secure the payment of all Secured
Obligations under and as defined therein.

not, except as expressly provided herein, operate as a waiver of any right,
power or remedy of any Lender, any Issuing Bank, the Arranger, the Documentation
Agent or the Agent under any of the Loan Documents, nor constitute a waiver or
amendment of any provision of any of the Loan Documents.

of which when so executed and delivered shall be deemed to be an original and
all of which taken together shall constitute but one and the same agreement.
