compliance with the covenants set forth in Section 7.1 of the Credit Agreement
for the Fiscal Quarter ending, and as of the last day of the Fiscal Quarter
ended, on or closest to September 30, 2001; provided that the waiver granted in
this Section 3 is limited expressly to the defaults herein described and shall
not be deemed to be a waiver of non-compliance with any other provision of the

      4. Acknowledgments and Confirmations. The Borrower and each Subsidiary
Guarantor acknowledges and confirms that the Liens granted pursuant to the Loan
Documents secure, without limitation, the Indebtedness, liabilities and

with the same effect as though made on and as of the date hereof, except for
such matters as are set forth in a certificate of an Authorized Officer of the

not disclosed to the Administrative Agent in writing prior to the Amendment No.
1 Effective Date.

            (b) After giving effect to the waiver set forth in Section 3 hereof,

of notice or

                                      -5-

Agreement and the other Loan Documents shall remain in full force and effect in
accordance with their terms and are hereby ratified and confirmed. The
execution, delivery and effectiveness of this Amendment shall not operate as a
waiver of any right, power or remedy of the Administrative Agent or the Lenders
under the Credit Agreement, nor constitute a waiver of any provision of the
Credit Agreement, except as specifically set forth herein.

      7. Miscellaneous.

            (a) The Borrower shall pay the Administrative Agent upon demand for
all reasonable expenses, including reasonable attorneys' fees and expenses of

conflicts with or results in any breach or contravention of, or the creation of
any Lien under, any document evidencing any contractual obligation to which the
