Credit Agreement dated as of September 8, 2004 (as amended, restated,
supplemented or otherwise modified, the "Credit Agreement"; capitalized terms
used herein but not defined shall be used herein as defined in the Credit
Agreement).

                  (2) The Borrower desires to convert outstanding Term B Loans
under the Credit Agreement to a new class of Loans under the Credit Agreement,
having identical terms with, and having the same rights and obligations under
the Loan Documents, as the Term B Loans, as set forth in the Loan Documents,
except as such terms are amended hereby (the "Term B1 Loans").

                  (3) The Borrower has received Net Cash Proceeds from an equity
Financing which it applied in accordance with Section 2.2(c) of the Credit
Agreement to prepay a portion of the Term B Loans and to prepay $50,000,000 of
the Second Lien Financing.

                  (4) Each Lender that has a Term B Loan outstanding as of the
date hereof (each, a "Term B Lender") who executes and delivers this Amendment
No. 2 shall be deemed, upon the effectiveness of this Amendment No. 2, to have
converted its Term Loan B Commitment and Term B Loans (which Term Loan B
Commitment and Term B Loans shall thereafter be deemed terminated and refinanced
in full) to a Converted Term B1 Commitment (as hereinafter defined) and Term B1
Loans, respectively, with such Converted Term B1 Commitment, in the same
aggregate principal amount as such Lender's outstanding Term B Loans,
immediately prior to the effectiveness of this Amendment No. 2, as set forth in
the Commitment Schedule to the Credit Agreement, as amended as of the Amendment
No. 2 Effective Date (as hereinafter defined) (the "Amended Commitment
Schedule"), and such Term B Lender shall thereafter become a Term B1 Lender (as
hereinafter defined).



                  (5) Each Person who executes and delivers this Amendment No. 2
as an additional Term B1 Lender (each, an "Additional Term B1 Lender"), will
make Term B1 Loans in the aggregate amount of its Additional Term B1 Commitment
(as hereinafter defined) on the Amendment No. 2 Effective Date (as hereinafter
defined) (each, an "Additional Term B1 Loan") to the Borrower in an aggregate
principal amount equal to the amount set forth opposite its name on the Amended
Commitment Schedule, the proceeds of which will be used by the Borrower, in
part, to refinance in full the outstanding principal amount of Term B Loans of
Term B Lenders, if any, who do not execute and deliver this Amendment No. 2, it
being understood that an Additional Term B1 Lender may be a Term B Lender prior
to the Amendment No. 2 Effective Date.

                  (6) The Borrower shall pay to each Term B Lender all accrued
and unpaid interest on its Term B Loans to the Amendment No. 2 Effective Date on
such Amendment No. 2 Effective Date.

                  (7) The Borrower has requested that the Required Lenders (a)
