A G R E E M E N T

Section 1. Amendments to the Agreement. The Agent, the Lenders, and the Borrower agree that the Agreement shall be amended as follows:

A. Section 1.2(ii) is hereby renumbered as Section 1.2(i).

B. Section 1.2(i)(A) (formerly Section 1.2(ii)(A)) is hereby amended to read as follows:

“(A) Subject to the limitations set forth below, the Agent is authorized by the Borrower and the Lenders, from time to time in the Agent’s sole discretion, (1) after the occurrence of a Default or an Event of Default, or (2) at any time that any of the other conditions precedent set forth in Article 8 have not been satisfied, to make Base Rate Revolving Loans to the Borrower on behalf of the Lenders in an aggregate amount outstanding at any time not to exceed 5% of the Borrowing Base (but in any event not to exceed the Maximum Revolver Amount) which the Agent, in its reasonable business judgment, deems necessary or desirable (x) to preserve or protect the Collateral, or any portion thereof, (y) to

enhance the likelihood of, or maximize the amount of, repayment of the Loans and other Obligations, or (z) to pay any other amount chargeable to the Borrower pursuant to the terms of this Agreement, including costs, fees and expenses as described in Section 13.7 (any of such advances are herein referred to as “Agent Advances”); provided, that, the Majority Lenders may at any time revoke the Agent’s authorization to make Agent Advances. Any such revocation must be in writing and shall become effective prospectively upon the Agent’s receipt thereof.”

C. Section 1.5 is hereby amended to read as follows:

“Bank Products. The Borrower may request and the Agent may, in its sole and absolute discretion, arrange for the Borrower to obtain from any Lender or any Lender’s Affiliates, Bank Products although the Borrower is not required to do so. If Bank Products are provided by an Affiliate of any Lender, the Borrower agrees to indemnify and hold the Agent and the Lenders harmless from any and all costs and obligations now or hereafter incurred by the Agent or any of the Lenders which arise from any indemnity given by any Lender to its Affiliates related to such Bank Products; provided, however, nothing contained herein is intended to limit the Borrower’s rights, with respect to any Lender or such Lender’s Affiliates, if any, which arise as a result of the execution of documents by and between the Borrower and the Bank which relate to Bank Products. The agreement contained in this Section shall survive termination of this Agreement. The Borrower acknowledges and agrees that the obtaining of Bank Products from any Lender or such Lender’s Affiliates (a) is in the sole and absolute discretion of such Lender or such Lender’s Affiliates, and (b) is subject to all rules and regulations of such Lender or such Lender’s Affiliates.”

D. The last paragraph of Section 3.8 is hereby amended to read as follows:

“Notwithstanding anything to the contrary contained in this Agreement, unless so directed by the Borrower, or unless an Event of Default has occurred and is continuing, neither the Agent nor any Lender shall apply any payments which it receives to any LIBOR Rate Loan, except (a) on the expiration date of the Interest Period applicable to any such LIBOR Rate Loan, or (b) in the event, and only to the extent, that there are no outstanding Base Rate Loans and, in any event, the Borrower shall pay LIBOR breakage losses in accordance with Section 4.4. The Agent and the Lenders shall have the continuing and exclusive right to apply and reverse and reapply any and all such proceeds and payments to any portion of the Obligations. Amounts distributed with respect to any Debt arising out of Bank Products shall be the lesser of the applicable Bank Product Amount last reported to Agent or the actual Debt arising out of Bank Products as calculated by the methodology reported to Agent for determining the amount due. Agent shall have no obligation to calculate the amount to be distributed with respect to any Debt arising out of Bank Products, but may rely upon written notice of the amount (setting forth a reasonably detailed calculation) from the applicable Lender or Lender’s Affiliate which issued the Bank Product. In the absence of such notice, Agent may assume the amount to be distributed is the Bank Product Amount last reported to it.”

“‘Applicable Margin’ means

(i) with respect to Base Rate Revolving Loans and all other Obligations (other than the LIBOR Rate Loans, the Unused Line Fee and the Letter of Credit Fee), 0.00%;

(ii) with respect to LIBOR Revolving Loans, 1.50%;

(iii) with respect to the Unused Line Fee, 0.35%; and

(iv) with respect to the Letter of Credit Fee, 1.50%.

The Applicable Margins shall be adjusted (up or down) prospectively on a quarterly basis as determined by the Borrower’s Borrowing Base Certificates and Domestic Cash Reports (and, for purposes of Level I, quarterly unaudited or annual audited (as applicable) Financial Statements), commencing with the first day of the first calendar month that occurs more than 5 days after delivery of the Borrower’s quarter-end Borrowing Base Certificate and Domestic Cash Report (and, for purposes of Level I, quarterly unaudited or annual audited (as applicable) Financial Statements) to Agent for the fiscal quarter ending March 31, 2006. Adjustments in Applicable Margins shall be determined by reference to the following grid:

4

provided, however, that in order for the Borrower to obtain the favorable pricing set forth in Level I above (in addition to meeting the minimum threshold amount of Total Liquidity), the Parent, must maintain a minimum EBITDA of not less than $500,000,000.

All adjustments in the Applicable Margins after March 31, 2006 shall be implemented quarterly on a prospective basis, for each calendar month commencing at least 5 days after the date of delivery to the Agent of the quarter-end Borrowing Base Certificate and Domestic Cash Report (and, for purposes of Level I, quarterly unaudited or annual audited (as applicable) Financial Statements) evidencing the need for an adjustment. Concurrently with the delivery of each quarter-ending Borrowing Base Certificate and Domestic Cash Report (and, for purposes of Level I, quarterly unaudited or annual audited (as applicable) Financial Statement), the Borrower shall deliver to the Agent a certificate, signed by its chief financial officer or vice president of finance (or any other officer, acceptable to Agent, having similar responsibility and authority), setting forth in reasonable detail the basis for the continuance of, or any change in, the Applicable Margins. Failure to timely deliver such Borrowing Base Certificates and Domestic Cash Reports (and, for purposes of Level I, quarterly unaudited or annual audited (as applicable) Financial Statements) shall, in addition to any other remedy provided for in this Agreement, result in an increase in the Applicable Margins to the highest level set forth in the foregoing grid, until

5

the first day of the first calendar month following the delivery of those Borrowing Base Certificates and Domestic Cash Reports (and, for purposes of Level I, quarterly unaudited or annual audited (as applicable) Financial Statements) demonstrating that such an increase is not required. If a Default or Event of Default has occurred and is continuing at the time any reduction in the Applicable Margins is to be implemented, no reduction may occur until the first day of the first calendar month following the date on which such Default or Event of Default is waived or cured.”

M. The definition of “Bank Products” contained in Annex A to the Agreement is hereby amended to read as follows:

The Bank Product Amount may be changed from time to time upon written notice to Agent by applicable Lender or Lender’s Affiliate and Borrower. No Bank Product Amount may be established or increased at any time that a Default or Event of Default exists, or if a reserve in such amount would cause the aggregate amount of outstanding Revolver Loans to exceed the Borrowing Base.”

N. The definition of “Borrowing Base” contained in Annex A to the Agreement is hereby amended to read as follows:

“‘Borrowing Base’ means, at any time, an amount equal to: (a) the sum of (A) eighty-five percent (85%) of the Net Amount of Eligible Accounts (but for purposes of this calculation Eligible Accounts shall exclude Eligible Other Foreign Accounts), plus (B) the lesser of (1) $10,000,000 and (2) twenty five percent (25%) of the Net Amount of Eligible Other Foreign Accounts, plus (C) the Maximum Real Estate Loan Amount; minus (b) Reserves from time to time established by the Agent in its reasonable credit judgment.”

O. The definition of “Capital Expenditures” contained in Annex A to the Agreement is hereby deleted.

P. Clause (g) of the definition of “Eligible Accounts” contained in Annex A to the Agreement is hereby amended to read as follows:

“(g) owed by an Account Debtor which: (i) does not maintain its chief executive office in the United States of America or Canada (unless such Account Debtor is an Eligible Foreign Account Debtor or is the obligor in respect of an Eligible Other Foreign Account); or (ii) is not organized under the laws of the United States of America or Canada or any state or province thereof (unless such Account Debtor is an Eligible Foreign Account Debtor or is the obligor in respect of an Eligible Other Foreign Account); or (iii) is the government of any foreign country or sovereign state, or of any state, province, municipality, or other political subdivision thereof, or of any department, agency, public corporation, or other instrumentality thereof; except to the extent that such Account is secured or payable by a letter of credit satisfactory to the Agent in its discretion;”

Q. The definition of “LIBOR Rate” contained in Annex A to the Agreement is hereby amended to read as follows:

Where,

‘Offshore Base Rate’ means the rate per annum appearing on Telerate Page 3750 (or any successor page) as the London interbank offered rate for deposits in Dollars at approximately 11:00 a.m. (London time) two Business Days prior to the first day of such Interest Period for a term comparable to such Interest Period. If for any reason such rate is not available, the Offshore Base Rate shall be, for any Interest Period, the rate per annum appearing on Reuters Screen LIBO Page as the London interbank offered rate for deposits in Dollars at approximately 11:00 a.m. (London time) two Business Days prior to the first day of such Interest Period for a term comparable to such Interest Period; provided, however, if more than one rate is specified on Reuters Screen LIBO Page, the applicable rate shall be the arithmetic mean of all such rates. If for any reason none of the foregoing rates is available, the Offshore Base Rate shall be, for any Interest Period, the rate per annum determined by Agent as the rate of interest at which dollar deposits in the approximate amount of the LIBOR Rate Loan comprising part of such Borrowing would be offered by the Bank’s London Branch to major banks in the offshore dollar market at their request at or about 11:00 a.m. (London time) two Business Days prior to the first day of such Interest Period for a term comparable to such Interest Period.

‘Eurodollar Reserve Percentage’ means, for any day during any Interest Period, the reserve percentage (expressed as a decimal, rounded upward to the next  ¹/100^th of 1%) in effect on such day applicable to member banks under regulations issued from time to time by the Federal Reserve Board for determining the maximum reserve requirement

7

(including any emergency, supplemental or other marginal reserve requirement) with respect to Eurocurrency funding (currently referred to as “Eurocurrency liabilities”). The Offshore Rate for each outstanding LIBOR Rate Loan shall be adjusted automatically as of the effective date of any change in the Eurodollar Reserve Percentage.”

R. The definition of “Maximum Real Estate Loan Amount” contained in Annex A to the Agreement is hereby amended to read as follows:

“‘Maximum Real Estate Loan Amount’ means as of any date of determination, the difference of: (a) $60,375,000, minus (b) an amount equal to $900,000 multiplied by the number of full or partial months in the period commencing on November 1, 2005 and ending on the first day of the month of determination (such reductions to take effect on the first day of each such month).”

S. Annex A to the Agreement is hereby amended by adding the following definitions in the appropriate alphabetical order:

“‘Eligible Other Foreign Accounts’ means Eligible Accounts owing to Borrower by any Account Debtor that does not maintain its chief executive office in the United States or Canada or is not organized under the laws of the United States or any state thereof (which Account Debtor is not an Eligible Foreign Account Debtor).
