                  Mezzanine Facility with the Net Cash Proceeds from the sale or
                  issuance by the Borrower or any of its Restricted Subsidiaries

                  certificate as though made on and as of such date other than
                  any such representations or warranties that, by their terms,
                  refer to a date other than the date of such certificate; and

                           (ii) No event has occurred and is continuing that

<PAGE>

         the properties of the Borrower or any of its Subsidiaries, except such
         contraventions, violations or conflicts which could not be reasonably
         likely to have a Material Adverse Effect.

                  (b) No Governmental Authorization and no notice to or filing
         with, any Governmental Authority or any other third party is required
         for the due execution, delivery or performance by the Borrower of this

                  (c) This Amendment has been duly executed and delivered by the
         Borrower. This Amendment and the Credit Agreement as amended by this
         Amendment are legal, valid and binding obligations of the Borrower,
         enforceable against the Borrower in accordance with their respective
         terms, except to the extent that such enforcement may be subject to
         applicable bankruptcy, insolvency, reorganization, moratorium or other
         laws of general application relating to or affecting enforcement of
         creditors' rights and laws concerning equitable remedies.

SECTION 4. Reference to and Effect on the Loan Documents. (a) On and after the

Agreement", "hereunder", "hereof' or words of like import referring to the
Credit Agreement, and each reference in the Notes and each of the other Loan
Documents to "the Credit Agreement", "thereunder", "thereof' or words of like

         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, as amended by this
         Amendment.

                  (c) The execution, delivery and effectiveness of this
         Amendment shall not, except as expressly provided herein, operate as a
         waiver of any right, power or remedy of any Lender or the Agent under
         any of the Loan Documents, nor constitute a waiver of any provision of
         any of the Loan Documents.

SECTION 5. Costs, Expenses and Taxes. The Borrower agrees to pay on demand all
costs and expenses of the Agent in connection with the preparation, execution,
delivery and administration, modification and amendment of this Amendment and

<PAGE>

which taken together shall constitute but one and the same agreement. Delivery
of an executed counterpart of a signature page to this Amendment by telecopier

accordance with, the laws of the State of New York.
