                  1.3 Section 1.1 of the Credit Agreement is hereby amended to
insert alphabetically therein the following defined terms:

                  "Acquisition Period" means a period beginning with the month
                  in which the first Leverage Ratio Acquisition to occur after
                  December 17, 2003 is consummated and ending with the last
                  calendar day of the calendar month to occur eighteen months
                  after the month in which the Leverage Ratio Acquisition
                  occurred.

                  "Leverage Ratio Acquisition" means any acquisition of property
                  or other assets by either Borrower or any of their respective
                  Subsidiaries that is permitted under this Agreement and which,
                  after giving effect thereto, causes the Leverage Ratio, on a
                  pro forma basis on the date such acquisition is consummated,
                  to equal or exceed 3.00 to 1.00. In order for an acquisition
                  to constitute a Leverage Ratio Acquisition, the Borrowers
                  shall deliver to the Administrative Agent, prior to the
                  consummation of such acquisition, written evidence in form and
                  substance acceptable to the Administrative Agent supporting
                  the above-described pro forma calculation.

                  "Qualified Receivables Transaction" means any transaction or
                  series of transactions that may be entered into by the
                  Domestic Borrower or any Subsidiary pursuant to which the
                  Domestic Borrower or any Subsidiary may sell, convey or
                  otherwise transfer to a newly-formed Subsidiary or other
                  special-purpose entity, or any other Person, any accounts or
                  notes receivable and rights related thereto, provided that all
                  of the terms and conditions of such transaction or series of
                  transactions, including without limitation the amount and type
                  of any recourse to the Domestic Borrower or any Subsidiary
                  with respect to the assets transferred, are reasonably
                  acceptable to the Administrative Agent.

                  "Receivables Transaction Attributed Indebtedness" means the
                  amount of obligations outstanding under the legal documents
                  entered into as part of any Qualified Receivables Transaction
                  on any date of determination that would be characterized as
                  principal if such Qualified Receivables Transaction were
                  structured as a secured lending transaction rather than as a
                  purchase.

                  1.4 Each of Section 4.4(b)(i)(A), Section 4.4(b)(i)(B), and
Section 4.4(b)(ii) of the Credit Agreement is hereby amended in its entirety as
follows: "Intentionally Omitted".

                  1.5 Section 4.4(b)(iii) of the Credit Agreement is hereby
amended to delete therefrom the last sentence thereof and to substitute therefor
the following: "Notwithstanding the foregoing or anything to the contrary set
forth herein, (i) accounts or notes receivable sold by the Domestic Borrower in
connection with Qualified Receivables Transactions permitted under this
Agreement, including, without limitation, the requirements of Section 11.1(g),
shall not be subject to this Section 4.4(b)(iii) and no mandatory prepayment
shall be required in connection therewith, and (ii) upon and during the
continuance of a Default or an Event of Default, and upon notice from the
Administrative Agent, all Asset Sale Proceeds received by the Domestic Borrower
or any of its Subsidiaries shall be applied to make mandatory principal
prepayments of


                                       2
