“Repricing Prepayment” means the aggregate outstanding principal amount of Term Loans of any Lender that is prepaid by the Borrower with the proceeds of a substantially concurrent incurrence by the Company or any of its Subsidiaries of new replacement term loans that have a yield (whether comprised of interest rate, margins, fees that are payable to the Tranche B Lenders and/or the Delayed Draw Term Lenders and/or original issue discounts) or premiums lower than the yield or premiums, as applicable, in effect for the Term Loans immediately prior to such prepayment; provided, however, that the prepayment of the Term Loans in connection with the refinancing of all of the Facilities resulting in the termination of this Agreement shall not be deemed a Repricing Prepayment. For purposes of this Agreement, original issue discounts shall be equated to interest rates in a manner reasonably determined by the Administrative Agent and consistent with generally accepted financial practice, based on an assumed four-year average life to maturity.”

(e) by amending and restating clause (c) of Section 11.1 (Amendments, Waivers, Etc.) thereof to read as follows:

(c) If, in connection with any proposed amendment, modification, waiver or termination (a “Proposed Change”) requiring the consent of all affected Lenders, the consent of Requisite Lenders is obtained but the consent of other Lenders

whose consent is required is not obtained (any such Lender whose consent is not obtained as described in this Section 11.1 being referred to as a “Non-Consenting Lender”), then, so long as the Lender acting as the Administrative Agent is not a Non-Consenting Lender, at the Borrower’s request, the Administrative Agent or an Eligible Assignee acceptable to the Administrative Agent and, prior to an Event of Default that is continuing, the Borrower, shall have the right with the Administrative Agent’s consent and in the Administrative Agent’s sole discretion (but shall have no obligation) to purchase from such Non-Consenting Lender, and such Non-Consenting Lender agrees that it shall, upon the Administrative Agent’s request, sell and assign to the Lender acting as the Administrative Agent or such Eligible Assignee, all of the Revolving Credit Commitments and Revolving Credit Outstandings of such Non-Consenting Lender if such Non-Consenting Lender is a Revolving Credit Lender, all of the Tranche B Term Loans of such Non-Consenting Lender if such Non-Consenting Lender is a Tranche B Term Loan Lender and all of the Delayed Draw Term Commitments or Delayed Draw Term Loans of such Non-Consenting Lender if such Non-Consenting Lender is a Delayed Draw Term Lender, in each case for an amount equal to the principal balance of all such Revolving Loans, Tranche B Term Loans or Delayed Draw Term Loans, as applicable, held by the Non-Consenting Lender and all accrued interest and fees with respect thereto through the date of sale; provided, that, in the event any such proposed amendment, modification, waiver, consent or other change (i) reduces the yield (whether comprised of interest rate, margins, fees, original issue discounts or otherwise) payable hereunder to any Term Loan Lender and (ii) becomes effective on or prior to June 25, 2008, the purchase price payable to any Term Loan Lender that is a Non-Consenting Lender in connection with such proposed change shall be increased by 1.00% of such Non-Consenting Lender’s Ratable Portion of the aggregate principal amount of the Term Loans then outstanding. Each Lender agrees that, if it becomes a Non-Consenting Lender, such purchase and sale shall be consummated pursuant to an executed Assignment and Acceptance; provided, however, that the failure of any Non-Consenting Lender to execute an Assignment and Acceptance shall not render such purchase and sale (and the corresponding assignment) invalid and such assignment shall be recorded in the Register.
