WHEREAS, the Company, certain of its subsidiaries named therein, the several lenders whose names are set forth on the signature pages thereof, and the Administrative Agent have entered into that certain Credit Agreement, dated as of February 24, 2006, amended and restated in its entirety as of May 27, 2009 and further amended and restated in its entirety as of April 13, 2010 (as amended, supplemented or otherwise modified from time to time in accordance with the terms thereof, the “Credit Agreement”; unless the context otherwise requires or unless otherwise defined herein, all capitalized terms used in this Agreement shall have the meanings ascribed thereto in the Credit Agreement), which Credit Agreement grants the Company, certain applicable Lenders and the Administrative Agent an option to establish one or more separate tranches of commitments and loans subject, among other things, of the execution and delivery of an Extended Facility Agreement substantially in the form hereof;

NOW, THEREFORE, pursuant to Section 2.16 of the Credit Agreement, and in consideration of the mutual covenants and agreements herein contained, the receipt and sufficiency of which are hereby acknowledged, the parties hereto covenant and agree as follows:

Section 1 The Extended Facility. Subject to the terms and conditions set forth herein and in the Credit Agreement, each Extended Facility Lender severally agrees to extend the maturity date and, if applicable, the amortization schedule of the Facility described on Schedule I (the “Prior Facility”) on the Extended Facility Closing Date in the amount and percentage described on Schedule I, such extended Facility, the “Extended Facility”. The Extended Facility shall have the designation set forth on Schedule I.

Section 2 Repayment of Extended Facility Loans. Unless repayment is required on an earlier date in accordance with the terms of the Credit Agreement, the Company shall repay to the Extended Facility Lenders the aggregate principal amount of all Extended Facility Loans outstanding on the following dates in the respective amounts set forth opposite such dates based upon the specified percentage of the Original Principal Amount of the Extended Facility (which amounts shall be reduced as a result of the application of prepayments in accordance with the order of priority set forth in Section 2.04 of the Credit Agreement):

provided, that, as provided in the table above, the final principal repayment installment of the Extended Facility Loans shall be repaid on March 31, 2015, (such date the “Maturity Date” for the Extended Facility) and in any event shall be in an amount equal to the aggregate principal amount of all Extended Facility Loans outstanding on such date.

Section 3 Extended Facility Extension Fee. The Company shall pay to the Extended Facility Lenders, from the date hereof until the Extended Facility has been paid in full, an extension fee (the “Extension Fee”) with respect to the Extended Facility, which, at any time, shall be the percentage per annum on the aggregate outstanding principal amount under such Extended Facility, with such percentage being equal to the excess of (a) the applicable percentage per annum set forth below determined by reference to the Cash Flow Ratio as set forth in the most recent Compliance Certificate received by the Administrative Agent pursuant to Section 7.01(d) of the Credit Agreement over (b) the Applicable Rate in effect for the Prior Facility at such time (which, if the Prior Facility is no longer existing, shall be equal to zero):

Any increase or decrease in the applicable percentage described in clause (a) above resulting from a change in the Cash Flow Ratio shall become effective as of the first Business Day immediately following the date a Compliance Certificate is delivered pursuant to Section 7.01(d) of the Credit Agreement; provided, however, that if a

Compliance Certificate is not delivered when due in accordance with such Section, then the highest percentage set forth in the table above shall apply in respect of the Extended Facility as of the first Business Day after the date on which such Compliance Certificate was required to have been delivered. The Extension Fee shall be due and payable quarterly in arrears on the last Business Day of each March, June, September and December, commencing with the first such date to occur after the Extended Facility Closing Date, upon any prepayment or payment of the Extended Facility Loans, whether voluntary or involuntary, or by acceleration or otherwise, based upon the principal amount of such Loans then being prepaid, and on the Maturity Date for the Extended Facility. The Extension Fee shall be computed in accordance with Section 2.09 of the Credit Agreement.
