          letter of credit fees applicable during that Pricing Period.  The
          Incremental Commitment Fee shall be added to the Applicable Commitment
          Fee Rate in determining the commitment fees applicable during that
          Pricing Period."

          8.  Waiver of Intercompany Notes. The Loan Documents heretofore
              ----------------------------
required that notes evidencing intercompany indebtedness owed by the Restricted
Subsidiaries to the Borrower be pledged to the Administrative Agent as security

Administrative Agent to return these notes to the Borrower. For the avoidance of
doubt, the Administrative Agent and the Banks hereby waive any requirement
(formerly expressed in the Loan Documents) that any such notes be pledged to the
Administrative Agent and the Banks.

          9.  Representations and Warranties.  Borrower represents and warrants

referred to therein and shall not operate as a waiver of or a consent to non-
compliance with any other section of the Loan Agreement or any of the other Loan
Documents. The waivers contained in Section 6 and Section 7 are only effective
for the specific instances, for the specific purposes and for the specific
period for which given.

          11. Activation Fee.  In consideration of the execution of this
              --------------
Amendment by the Administrative Agent and the Required Lenders, Borrower agrees
that if as of the first day following the date of this Amendment upon which it
requests Loans under the Loan Agreement, the Funded Debt Ratio is effect as of
the last day of the then most recently ended Fiscal Quarter for which Borrower
has delivered a Compliance Certificate is in excess of 4.00:1.00, then Borrower
shall concurrently pay to each of the Lenders through the Administrative Agent

<PAGE>

activation fee of 1% (100 basis points) times the Pro Rata Share of the

          12.  Conditions Precedent.  The effectiveness of this Amendment is
               --------------------
conditioned upon the receipt by the Administrative Agent of the following, each

                    Commitment.

          13.  Confirmation.  In all respects, the terms of the Loan Agreement
               ------------
