               a Pro Forma Basis after giving effect to such Subordinated Debt
               (and any other Subordinated Debt consummated after the end of the
               immediately preceding fiscal quarter), and (iii) the Borrower
               shall prepay the Loans with the Net Proceeds of such Subordinated

               the disposition and shall have delivered to the Administrative

                  representations and warranties hereunder as of such date

is amended to read as follows:

                  provided, however, that the Borrower may refinance
                  Subordinated Debt with Subordinated Debt that has terms that
                  are not materially less favorable to the Borrower and its
                  Subsidiaries and has a weighted average maturity that is
                  greater than that of the Subordinated Debt being refinanced
                  so long as the Borrower shall have delivered to the
                  Administrative Agent a Pro Forma Compliance Certificate
                  demonstrating that, upon giving effect to such refinancing
                  on a Pro Forma Basis, the Borrower shall be in compliance
                  with all of the covenants set forth in Section 8.11;
                  provided, further, that to the extent any Net Proceeds
                  received from any Debt Transaction or Equity Transaction are
                  not required to be applied towards the prepayment of the Loans
                  under Section 3.3(b)(iii) and (iv) (and are not otherwise used
                  in connection with any Permitted Acquisition or Capital
                  Expenditures permitted under Section 8.11(f)), the Borrower
                  may use such Net Proceeds to repurchase, defease or reacquire
                  the Senior Notes and the Senior Subordinated Notes.

         2.21     Section 9.15 is amended to read as follows:

                  9.15 [Reserved].

         3.       The Guarantors join in the execution of this Amendment for
purposes of acknowledging and consenting to the terms of this Amendment and

         4.       The Borrower affirms that the representations and warranties
in the Credit Agreement and the other Credit Documents are true and correct in
all material respects as of the date hereof (except those which expressly relate
to an earlier period or date and except to the extent that changes in facts and
conditions on which such representations and warranties are based are required
or permitted under the Credit Agreement).

         5.       This Amendment shall be effective upon receipt by the
Administrative Agent of the following:

                  (a)      executed copies of Consents from the requisite
         Lenders, and executed signature pages to this Amendment from each of

                  (b)      the amendment fee payable to the Lenders consenting
         to this Amendment and any other fees payable in connection with this
         Amendment.

         6.       Except as modified hereby, all of the terms and provisions of
 the Credit Agreement (including Schedules and Exhibits) shall remain in full
 force and effect.

         7.       The Borrower agrees to pay all reasonable costs and expenses
