consent to the amendments to the existing Senior Subordinated Note Indenture on
the terms set forth in the Offer to Purchase and Consent Solicitation Statement
dated April 30, 2004 ("Offer to Purchase") and (b) consent to the purchase,
payment, prepayment, defeasance, retirement or other acquisition by the Borrower
of the existing Senior Subordinated Notes remaining outstanding after completion
of the Offer to Purchase as long as (1) no Default or Event of Default has
occurred and is continuing and (2) the transaction takes place on or prior to
December 31, 2004. The Lenders further agree that the provisions of Section 2.13
of the Credit Agreement shall not apply to the Net Cash Proceeds of any issuance
or incurrence by the Borrower or any of its Subsidiaries of any Capital Stock or
Indebtedness to the extent, but only to the extent, such Net Cash Proceeds are
used to effect one or more transactions in accordance with the foregoing clause
(b).

                  4. Representations and Warranties. The Borrower hereby
confirms that the representations and warranties set forth in Section 4 of the

all material respects as if made as of the Effective Date (except such
representations and warranties as are made as of a particular date, which such
representations and warranties shall be true and correct in all material
respects as if made as of such date). The Borrower represents and warrants that,
after giving effect to this First Amendment, no Default or Event of Default has
occurred and is continuing.

                  5. Effectiveness. This First Amendment shall become effective

First Amendment executed by the Borrower and the Required Lenders (the
"Effective Date").

                  6. Continuing Effect of the Credit Agreement. This First
Amendment shall not constitute an amendment of any provision of the Credit
Agreement not expressly referred to herein and shall not be construed as a
waiver or consent to any further or future action on the part of the Borrower
that would require a waiver or consent of the Lenders, the Administrative Agent
or the Other Agents. Except as expressly amended hereby, the provisions of the
Credit Agreement are and shall remain in full force and effect.

                  7. Counterparts. This First Amendment may be executed by the
parties hereto in any number of separate counterparts (including telecopied
counterparts), each of which shall be deemed to be an original, and all of which
taken together shall be deemed to constitute one and the same instrument.



                                                                               4


                  8. GOVERNING LAW. THIS FIRST AMENDMENT SHALL BE GOVERNED BY,
