NOW, THEREFORE, it is agreed:

I. Amendments to Credit Agreement

1.On, or within five Business Days after the occurrence of, the First Amendment Execution Date (as hereinafter defined) (subject to the receipt of a Borrowing Request in form and substance reasonably satisfactory to the Administrative Agent and substantially in accordance with the requirements of Section 2.03 of the Credit Agreement, and subject to a notice of prepayment of the Refinanced B Term Loans in accordance with the relevant requirements of Section 2.12(a) of the Credit Agreement, and subject to the relevant conditions specified in Section 4.01 of the Credit Agreement and the occurrence of the First Amendment Effective Date (as hereinafter defined)), each Lender with a B Term Loan Commitment as set forth in the Register as of First Amendment Effective Date hereby agrees to make a B Term Loan in the respective principal amount set forth opposite its name under the heading “B Term Loan Commitment” in the Register as of the First Amendment Effective Date, in each case in accordance with the relevant requirements of the Credit Agreement except that (i) the date of the making of the B Term Loans described in this paragraph, other than those B Term Loans being converted into Replacement B Term Loans, shall be as set forth above and (ii) each Lender with a B Term Loan Commitment as set forth in the Register as of the First Amendment Effective Date shall make the respective B Term Loan available (through the Administrative Agent) in cash, except that each Lender with a B Term Loan Commitment as shown in the Register as of the First Amendment Effective Date with existing B Term Loans outstanding immediately prior to the occurrence of the First Amendment Effective Date shall convert its theretofore outstanding B Term Loans (in a principal amount up to, but not in excess of, the B Term Loan of such Lender as specified in the Register on the date hereof) into Replacement B Term Loans hereunder without any requirement that it make cash proceeds available to the Borrower (except to the extent that the B Term Loan Commitment of such Lender as specified in the Register as of the First Amendment Effective Date exceeds the principal amount of its therefore outstanding B Term Loans). The Borrower shall direct the Administrative Agent to apply (and the Administrative Agent shall apply) all cash proceeds of Replacement B Term Loans made hereunder to refinance then outstanding Refinanced B Term Loans pursuant to the Credit Agreement (before giving effect to the First Amendment) other than those B Term Loans being converted into Replacement B Term Loans. It is understood that the Replacement B Term Loans being made pursuant to this First Amendment (whether by conversion or the making of cash proceeds available to the Borrower to refinance Refinanced B Term Loans) shall constitute Replacement Term Loans pursuant to Section 9.08(c) of the Credit Agreement and the B Term Loans being refinanced or converted shall constitute Refinanced Term Loans as described therein. It is understood and agreed by all parties hereto that the aggregate principal amount of B Term Loans outstanding after giving effect to the First Amendment Effective Date shall be equal to the aggregate amount of B Term Loans which were outstanding immediately prior to giving effect thereto. Any Lender holding outstanding B Term Loans immediately prior to the First Amendment Effective Date, that does not (in its sole discretion) provide a B Term Loan Commitment pursuant hereto, shall have its outstanding B Term Loans repaid in full on the First Amendment Effective Date (if same occurs). On the First Amendment Effective Date, the aggregate amount of Replacement B Term Loans (including those made by conversion or the

Page 2 of 12

Exhibit 10.21

making of cash proceeds available to the Borrower) shall be comprised of the same number of Borrowings as were applicable to the outstanding Refinanced B Term Loan immediately prior to the First Amendment Effective Date, which Borrowings shall be of the same Types and in the same amounts as the Borrowings theretofore applicable to the Refinanced B Term Loans, and in the case of any such Borrowings of Eurodollar Loans shall have the same Interest Period (i.e. continuing to the date of the expiration Interest Period theretofore applicable to the corresponding Borrowing of Refinanced B Term Loan) and the same Adjusted LIBO Rate (although, from and after the First Amendment Effective Date, the LIBOR Margins and ABR Margins applicable thereto shall be determined in accordance with Schedule A to the Credit Agreement, as amended pursuant to following paragraph numbered 4) applicable thereto on the First Amendment Effective Date. Each Lender with Replacement B Term Loans shall participate on a pro rata basis in each outstanding Borrowing of Replacement B Term Loans as described in the immediately preceding sentence. In connection with the incurrence of the Replacement B Term Loans and the repayment of Refinanced B Term Loans in accordance with this First Amendment, the Borrower hereby agrees that, notwithstanding anything to the contrary contained in the Credit Agreement, (i) if requested by any Lender making cash proceeds available to the Borrower pursuant to the Replacement B Term Loans (but not with respect to that portion of the Replacement B Term Loans of any Lender constituting a conversion of Refinanced B Term Loans of such Lender), the Borrower shall pay to such Lender such amounts necessary, as reasonably determined by such Lender, to compensate such Lender for making such Replacement B Term Loans in the middle of an existing Interest Period (rather than at the beginning of the respective Interest Period, based upon the rates then applicable thereto) and (ii) the Borrower shall be obligated to pay to each Lender whose B Term Loans are being repaid in cash (rather than converted into Replacement B Term Loans on the First Amendment Effective Date) amounts of the type referred to in Section 2.15 of the Credit Agreement in connection with its repayment in cash (but not by way of conversion of Refinanced B Term Loans into Replacement B Term Loans as contemplated above) of such Refinanced B Term Loans of such Lender incurred in connection with the conversion of Refinanced B Term Loans and/or the actions taken pursuant to the preceding sentence of this Section I.1.

2.For the avoidance of doubt, it is understood and agreed that the amounts of the remaining scheduled prepayments of principal of the B Term Loans after giving effect to this First Amendment shall remain unchanged from the schedule set forth in Section 2.11(a) of the Credit Agreement, except that the scheduled repayments for March 31, 2005, June 30, 2005 and September 30, 2005 have already been repaid in full. The schedule of remaining repayments, as calculated on the date hereof, for the Replacement B Term Loans is set forth below:

Category B Period	2.50%	2.00%	1.50%	1.00%

The “LIBOR Margin” and the “ABR Margin” for any date shall be determined by reference to the “Category Period” in effect as of the last day of the fiscal quarter most recently ended as of such date and any change shall become effective upon the delivery to the Administrative Agent of the financial statements to be delivered pursuant to Section 5.04 for the most recently ended fiscal quarter together with a certificate of a Responsible Officer of the Borrower (a) setting forth in reasonable detail the calculation of the Net Leverage Ratio for the end of such fiscal quarter and (b) stating that such Responsible Officer has reviewed the terms of this Agreement and the other Loan Documents and has made, or caused to be made under his or her supervision, a review in reasonable detail of the transactions and condition of Holdings, the Borrower and their Subsidiaries during the accounting period, and that such Responsible Officer does not have knowledge of the existence as at the date of such officers’ certificate of any Event of Default or Default. Notwithstanding the foregoing, at the time Holdings shall have received cash proceeds from the sale after the Closing Date of its Equity Interests pursuant to a public offering of common stock, if a Responsible Officer of Holdings shall deliver to the Administrative Agent a certificate demonstrating in reasonable detail that the Borrower would qualify for a different Category Period (determined on a Pro Forma Basis as of the last day of the last Test Period ended prior to the date on which Holdings shall have received cash proceeds from the sale after the Closing Date of its Equity Interests pursuant to a public offering of common stock for which financial statements have been made available (or were required to be made available) pursuant to Section 5.04), then the Category Period that would otherwise be applicable as set forth in such certificate shall thereafter be applicable (until same is changed or ceases to apply in accordance with the second preceding sentence). For the purposes of this Schedule A:

“Category A Period” shall exist at any time no other Category Period is then in effect.

Notwithstanding the foregoing, at any time during which (i) the Borrower has failed to deliver the certificate required under Section 5.04(c) with respect to a fiscal quarter following the date the delivery thereof is due or (ii) a Default or Event of Default is in existence, the Category Period shall be deemed, solely for the purposes of this Schedule A, to be a Category A Period, until such time as the Borrower shall deliver such certificate or such Default or Event of Default shall be cured or waived.
