13

giving effect to any such increase in the Tranche A Loan Limit or the Tranche B Loan Limit, as applicable, and the Maximum Credit, the performance of the terms and conditions of this Agreement and the other Financing Agreements and the incurrence of Obligations by Borrowers and Guarantors (1) are within each Borrower’s and Guarantor’s corporate or limited liability company powers, (2) have been duly authorized by each Borrower and Guarantor, (3) are not in contravention of law or the terms of any Borrower’s or Guarantor’s certificate of incorporation, certificate of formation, by laws, operating agreement or other organizational documentation, or any indenture (including the Indenture), agreement or undertaking to which any Borrower or Guarantor is a party or by which any Borrower or Guarantor or its property are bound, and (4) will not result in the creation or imposition of, or require or give rise to any obligation to grant, any lien, security interest, charge or other encumbrance upon any property of any Borrower or Guarantor, other than the liens in favor of Agent;

“Borrowers agree to pay to Tranche B Lenders the other fees and amounts set forth in the Tranche B Fee Letter in the amounts and at the times specified therein.”

7. Payments. Section 6.4 of the Loan Agreement is hereby amended by inserting the following sentence after the second sentence of such Section:

“Notwithstanding anything to the contrary contained in the immediately prior sentence or any of the other provisions of this Agreement or any of the other Financing Agreements, upon and after the occurrence and during the continuance of a Triggering Event or any other time as Agent may elect when the aggregate outstanding principal amount of the Tranche A Loans and the aggregate outstanding principal amount of the Tranche B Loans are not held ratably among the Lenders in accordance with their respective Pro Rata Shares (determined in accordance with the terms of clause (c) of the definition of Pro Rata Share based on the respective Commitments of Lenders or, if the Commitments are terminated, based on the respective Commitments of Lenders in effect immediately preceding such termination), Agent shall apply payments received or collected from any Borrower or Guarantor or for the account of any Borrower or Guarantor (including the monetary proceeds of collections or of realization upon any Collateral) as follows (subject to the provisions of the Intercreditor Agreement): first, to pay any fees, indemnities or expense reimbursements then due to Agent and Collateral Agent from any Borrower or Guarantor; second, to pay any fees, indemnities or expense reimbursements then due to Lenders from any Borrower or Guarantor; third, to pay interest due in respect of any Loans; fourth, to pay principal in respect of the Tranche A Loans or principal in respect of the Tranche B Loans, as applicable, in either case until the aggregate principal amount of the Tranche A Loans and the Tranche B Loans are outstanding ratably among the Lenders in accordance with their respective Pro Rata Shares (determined in accordance with the terms of clause (c) of the definition of Pro Rata Share based on the respective Commitments of Lenders or, if the Commitments are terminated, based on the respective Commitments of Lenders in effect immediately preceding such termination); fifth, to pay principal in respect of all Loans and to pay or prepay Obligations arising under or pursuant to any Hedge Agreements of a Borrower or Guarantor with an Affiliate of Agent (up to the amount of any then effective Reserve established in respect of such Obligations), on a pro rata basis; sixth, to pay or prepay any other Obligations (excluding Obligations arising under or pursuant to Hedge Agreements) whether or not then due, in such order and manner as Agent determines, on a pro rata

Agent and Lenders are authorized to make the Loans and provide the Letter of Credit Accommodations based upon telephonic or other instructions received from anyone purporting to be an officer of Administrative Borrower or other authorized person or, at the discretion of Agent, if such Loans are necessary to satisfy any Obligations. All requests for Tranche A Loans or Letter of Credit Accommodations hereunder shall specify the Business Day on which the requested Tranche A Loan is to be made or Letter of Credit Accommodation provided and the amount of the requested Tranche A Loan, and any such request received after 11:00 a.m. New York City time on any Business Day shall be deemed to have been made as of the opening of business on the immediately following Business Day. All requests for Tranche B Loans hereunder shall specify the Business Day on which the requested Tranche B Loan is to be made (which shall be at least five (5) Business Days following the date of such request) and the amount of the requested Tranche B Loan. All Loans and Letter of Credit Accommodations under this Agreement shall be conclusively presumed to have been made to, and at the request of and for the benefit of, any Borrower or Guarantor when deposited to the credit of any Borrower or Guarantor or otherwise disbursed or provided in accordance with the instructions of any Borrower or Guarantor or in accordance with the terms and conditions of this Agreement.”

16

10. Settlement Procedures. Section 6.10 of the Loan Agreement is hereby amended by deleting such Section in its entirety and replacing it with the following:

“(a) In order to administer the Credit Facility in an efficient manner and to minimize the transfer of funds between Agent and Tranche A Lenders, Agent shall, to the extent that the aggregate amount of Tranche A Loans since the last day of the immediately preceding Settlement Period plus the amount of the requested Tranche A Loans does not exceed $20,000,000 (such Tranche A Loans in an amount not in excess of $20,000,000 are hereinafter referred to as the “Swingline Loans”), and otherwise Agent may, at its option, in any case subject to the terms of this Section, make available, on behalf of Tranche A Lenders and in accordance with the terms of this Agreement, the full amount of the Tranche A Loans requested or charged to any Borrower’s loan account or otherwise to be advanced by Tranche A Lenders pursuant to the terms hereof, without requirement of prior notice to Tranche A Lenders of the proposed Tranche A Loans.

(b) With respect to all Tranche A Loans made by Agent on behalf of Tranche A Lenders as provided in this Section, the amount of each Tranche A Lender’s Pro Rata Share of the outstanding Tranche A Loans shall be computed weekly (or, in the case of Swingline Loans, computed at such time as Agent may determine), and shall be adjusted upward or downward on the basis of the amount of the outstanding Tranche A Loans as of 5:00 p.m. New York City time on the Business Day immediately preceding the date of each applicable settlement computation; provided, that, Agent retains the absolute right at any time or from time to time to make the above described adjustments at intervals more frequent than weekly, but in no event more than twice in any week. Agent shall deliver to each of the Tranche A Lenders after the end of each week (or, in the case of Swingline Loans, at such times as Agent may determine), or at such other period or periods as Agent shall determine, a summary statement of the amount of outstanding Tranche A Loans (other than Swingline Loans) and Swingline Loans, as applicable, for such period (such week or other period or periods being hereinafter referred to as a “Settlement Period”). If the summary statement is sent by Agent and received by a Tranche A Lender prior to 12:00 p.m. New York City time on any Business Day, then such Tranche A Lender shall make the settlement transfer described in this Section by no later than 3:00 p.m. New York City time on the same Business Day and if received by a Tranche A Lender after 12:00 p.m. New York City time, then such Tranche A Lender shall make the settlement transfer by not later than 3:00 p.m. New York City time on the next Business Day following the date of receipt. If, as of the end of any applicable Settlement Period, the amount of a Tranche A Lender’s Pro Rata Share of the outstanding Tranche A Loans (excluding Swingline Loans) or Swing Line Loans, as applicable, is more than such Tranche A Lender’s Pro Rata Share of the outstanding Tranche A Loans (excluding Swingline Loans) or Swing Line Loans, respectively, as of the end of the previous applicable Settlement Period, then such Tranche A Lender shall forthwith (but in no event later than the time set forth in the preceding sentence) transfer to Agent by wire transfer in immediately

17

available funds the amount of the increase. Alternatively, if the amount of a Tranche A Lender’s Pro Rata Share of the outstanding Tranche A Loans (excluding Swingline Loans) or Swing Line Loans, as applicable, as of the end of any applicable Settlement Period is less than the amount of such Tranche A Lender’s Pro Rata Share of the outstanding Tranche A Loans (excluding Swingline Loans) or Swing Line Loans, respectively, as of the end of the previous applicable Settlement Period, Agent shall forthwith transfer to such Tranche A Lender by wire transfer in immediately available funds the amount of the decrease. The obligation of Agent and each of the Tranche A Lenders to transfer such funds and effect such settlement shall be irrevocable and unconditional and without recourse to or warranty by the Tranche A Lenders or Agent, as the case may be. Agent and each Tranche A Lender agrees to mark its books and records at the end of each Settlement Period to show at all times the dollar amount of its Pro Rata Share of the outstanding Tranche A Loans and Letter of Credit Accommodations. Each Tranche A Lender shall only be entitled to receive interest on its Pro Rata Share of the Tranche A Loans to the extent such Tranche A Loans have been funded by such Tranche A Lender. Because Agent on behalf of Tranche A Lenders may be advancing and/or may be repaid Tranche A Loans prior to the time when Tranche A Lenders will actually advance and/or be repaid such Tranche A Loans, interest with respect to Tranche A Loans shall be allocated by Agent in accordance with the amount of Tranche A Loans actually advanced by and repaid to each Tranche A Lender and Agent and shall accrue from and including the date such Tranche A Loans are so advanced to but excluding the date such Tranche A Loans are either repaid by Borrowers or actually settled with the applicable Tranche A Lender as described in this Section.

(c) To the extent that Agent has made any such amounts available and the settlement described above shall not yet have occurred, upon repayment of any Tranche A Loans by a Borrower, Agent may apply such amounts repaid directly to any amounts made available by Agent pursuant to this Section. In lieu of periodic settlements, Agent may, at its option, at any time require each Tranche A Lender to provide Agent with immediately available funds representing its Pro Rata Share of each Tranche A Loan, prior to Agent’s disbursement of such Tranche A Loan to (or for the benefit of) a Borrower. In such event, all Tranche A Loans under this Agreement shall be made by Tranche A Lenders simultaneously and proportionately to their Pro Rata Shares. Each Tranche B Lender shall be required to provide Agent with immediately available funds representing its Pro Rata Share of each Tranche B Loan, prior to Agent’s disbursement of such Tranche B Loan to (or for the benefit of) a Borrower.

(d) If Agent is not funding a particular Tranche A Loan to a Borrower (or Administrative Agent for the benefit of such Borrower) pursuant to this Section on any day, Agent may assume that each Tranche A Lender will make available to Agent such Tranche A Lender’s Pro Rata Share of the Tranche A Loan requested or otherwise made on such day and Agent may, in its discretion, but shall not be obligated to, cause a corresponding amount to be made available to or for the benefit of such Borrower on such day. If Agent makes such

18

corresponding amount available to a Borrower and such corresponding amount is not in fact made available to Agent by such Tranche A Lender, Agent shall be entitled to recover such corresponding amount on demand from such Tranche A Lender together with interest thereon for each day from the date such payment was due until the date such amount is paid to Agent at the Federal Funds Rate for each day during such period (as published by the Federal Reserve Bank of New York or at Agent’s option based on the arithmetic mean determined by Agent of the rates for the last transaction in overnight Federal funds arranged prior to 9:00 a.m. (New York City time) on that day by each of the three leading brokers of Federal funds transactions in New York City selected by Agent) and if such amounts are not paid within three (3) days of Agent’s demand, at the highest Interest Rate provided for in Section 3.1 hereof applicable to Prime Rate Loans. During the period in which such Tranche A Lender has not paid such corresponding amount to Agent, notwithstanding anything to the contrary contained in this Agreement or any of the other Financing Agreements, the amount so advanced by Agent to or for the benefit of any Borrower shall, for all purposes hereof, be a Tranche A Loan made by Agent for its own account. Upon any such failure by a Tranche A Lender to pay Agent, Agent shall promptly thereafter notify Administrative Borrower of such failure and Borrowers shall pay such corresponding amount to Agent for its own account within five (5) Business Days of Administrative Borrower’s receipt of such notice.

(e) A Lender who defaults in any of its material obligations hereunder, fails to pay Agent its Pro Rata Share of any Loans made available by the Agent on such Lender’s behalf, or fails to pay any other amount owing by it to Agent, is a “Defaulting Lender”. Agent shall not be obligated to transfer to a Defaulting Lender any payments received by Agent for the Defaulting Lender’s benefit, nor shall a Defaulting Lender be entitled to the sharing of any payments hereunder (including any principal, interest or fees). Amounts payable to a Defaulting Lender shall instead be paid to or retained by Agent. Agent may hold and, in its discretion, relend to a Borrower the amount of all such payments received or retained by it for the account of such Defaulting Lender. For purposes of voting or consenting to matters with respect to this Agreement and the other Financing Agreements and determining Pro Rata Shares, such Defaulting Lender shall be deemed not to be a “Lender” and such Lender’s Commitment shall be deemed to be zero (0). This Section shall remain effective with respect to a Defaulting Lender until such default is cured. The operation of this Section shall not be construed to increase or otherwise affect the Commitment of any Lender, or relieve or excuse the performance by any Borrower or Obligor of their duties and obligations hereunder.

(f) No Lender shall be responsible for any default by any other Lender in the other Lenders’ obligations to make Loans requested hereunder nor shall the Commitment of any Lender be increased or decreased as a result of the default by any other Lender in the other Lenders’ obligations to make Loans hereunder. Nothing in this Section or elsewhere in this Agreement or the other Financing Agreements shall be deemed to require Agent to advance funds on behalf of any

19

Lender or to relieve any Lender from its obligation to fulfill its Commitment hereunder or to prejudice any rights that any Borrower may have against any Lender as a result of any default by any Lender hereunder in fulfilling its Commitment.”

11. Collateral Reporting. Section 7.1(a)(i) of the Loan Agreement is hereby amended by (a) deleting the reference to “Lender” and replacing it with “Agent”, (b) deleting “and” appearing at the end of clause (C) of such Section and replacing it with a comma, and (c) inserting the following immediately prior to the semicolon at the end of such Section:

13. Transactions with Affiliates. Section 9.12(b) of the Loan Agreement is hereby amended by (a) deleting the word “and” appearing at the end of the proviso to clause (ii) of such Section and (b) inserting the following immediately prior to the period at the end of such Section:

“, and (iv) amounts payable to Equity Affiliated Lenders pursuant to this Agreement or any of the other Financing Agreements”.

14. Capital Expenditures. Section 9.25 of the Loan Agreement is hereby amended by deleting such Section in its entirety and replacing it with the following:

“9.25 Capital Expenditures. Group and its Subsidiaries shall not directly or indirectly, make or commit to make, whether through purchases, capital leases or otherwise, Capital Expenditures in an aggregate amount in excess of $13,500,000 during the fiscal year of Group ended on or about December 31, 2007, $25,000,000 during the fiscal year of Group ended on or about December 31, 2008 and $21,000,000 during each fiscal year of Group thereafter (each, a “Section 9.25 Test Year”); provided, that, if the Adjusted Excess Availability is equal to or greater than $20,000,000 for each of the ten (10) consecutive days immediately preceding the last day of any Section 9.25 Test Year, then Group and its Subsidiaries shall not be required to comply with the terms of this Section 9.25 for such Section 9.25 Test Year.”

If such funds are not made available to Agent by such Lender, Agent shall be entitled to recover such funds, on demand from such Lender together with interest thereon for each day from the date such payment was due until the date such amount is paid to Agent at the Federal Funds Rate for each day during such period (as published by the Federal Reserve Bank of New York or at Agent’s option based on the arithmetic mean determined by Agent of the rates for the last transaction in overnight Federal funds arranged prior to 9:00 a.m. (New York City time) on that day by each of the three leading brokers of Federal funds transactions in New York City selected by Agent) and if such amounts are not paid within three (3) days of Agent’s demand, at the highest Interest Rate provided for in Section 3.1 hereof applicable to Prime Rate Loans.”

18. Successor Agent. Section 12.13 of the Loan Agreement is hereby amended by deleting the second sentence from such Section in its entirety and replacing it with the following:
