SECTION 1. 2013 Replacement Term Loan Amendment to Credit Agreement.

(a) (i) Subject to the satisfaction of the conditions set forth in Section 4 hereof, the 2013 Replacement Term Lenders hereby agree to make 2013 Replacement Term Loans to the Borrower on the Amendment No. 4 Effective Date (as defined below) in the aggregate principal amount of $923,375,000 to refinance all outstanding Replaced Term Loans in accordance with the relevant requirements of the Credit Agreement and this Amendment No. 4. It is understood and agreed that the 2013 Replacement Term Loans (as defined below) being made pursuant to this Amendment No. 4 shall constitute “Replacement Term Loans” as defined in, and pursuant to, Section 10.01 of the Credit Agreement and the Replaced Term Loans being refinanced shall constitute “Refinanced Term Loans” as defined in, and pursuant to, Section 10.01 of the Credit Agreement. Except as expressly provided in Amendment No. 4 (including as to the Applicable Rate, Maturity Date and call protection) and the Credit Agreement (as modified hereby), the 2013 Replacement Term Loans shall be on terms identical to the Replaced Term Loans (including as to Guarantors, Collateral (and ranking) and payment priority).

(ii) The Administrative Agent has prepared a schedule (the “2013 Replacement Term Loan Commitment Schedule”) which sets forth the allocated term loan commitments received by it (the “2013 Replacement Term Loan Commitments”) from the 2013 Replacement Term Lenders. The Administrative Agent has notified each 2013 Replacement Term Lender of its allocated 2013 Replacement Term Loan Commitment, and each of the 2013 Replacement Term Lenders is listed as a signatory to this Amendment No. 4. On the Amendment No. 4 Effective Date, all then outstanding Replaced Term Loans shall be refinanced in full as follows:

(w) the outstanding principal amount of the Replaced Term Loan of each Lender which (i) is an existing Lender under the Credit Agreement prior to giving effect to this Amendment No. 4 (each, an “Existing Lender”) and (ii) does not have a 2013 Replacement Term Loan Commitment (a Lender meeting the requirements of clauses (i) and (ii), each, a “Non-Converting Lender”) shall be repaid in full in cash;

(x) to the extent any Existing Lender has a 2013 Replacement Term Loan Commitment (each, a “Converting Lender”) that is less than the full outstanding principal amount of the Replaced Term Loan of such Lender, such Lender shall be repaid in cash in an amount equal to the difference between the outstanding principal amount of the Replaced Term Loan of such Lender and such Lender’s 2013 Replacement Term Loan Commitment (such difference, the “Non-Converting Portion”);

(y) the outstanding principal amount of the Replaced Term Loan of each Converting Lender shall automatically be converted into a term loan (each, a “Converted 2013 Replacement Term Loan”) in a principal amount equal to such Converting Lender’s Replaced Term Loan less an amount equal to any Non-Converting Portion of such Converting Lender’s Replaced Term Loan (the “Term Loan Conversion”); and

2

(z) (1) each Person with a 2013 Replacement Term Loan Commitment that is not an Existing Lender (each, a “New 2013 Replacement Term Lender”) and (2) each Converting Lender with a 2013 Replacement Term Loan Commitment in an amount in excess of the principal amount of the Replaced Term Loan of such Converting Lender (the commitment of each New 2013 Replacement Term Lender and any such difference as to any Converting Lender, each being a “New 2013 Replacement Term Loan Commitment”), agrees to make to the Borrower a new term loan (each, a “New 2013 Replacement Term Loan” and, collectively, the “New 2013 Replacement Term Loans” and, together with the Converted 2013 Replacement Term Loans, the “2013 Replacement Term Loans”) in a principal amount equal to such New 2013 Replacement Term Lender’s 2013 Replacement Term Loan Commitment or such Converting Lender’s New 2013 Replacement Term Loan Commitment, as the case may be, on the Amendment No. 4 Effective Date.

(iii) Each 2013 Replacement Term Lender hereby agrees to “fund” its 2013 Replacement Term Loan in an aggregate principal amount equal to such 2013 Replacement Term Lender’s 2013 Replacement Term Loan Commitment as follows: (x) each Converting Lender shall “fund” its 2013 Replacement Term Loan to the Borrower by converting all or a portion of its then outstanding principal amount of Replaced Term Loan into a 2013 Replacement Term Loan in an equal principal amount as provided in clause (ii)(y) above, (y) (1) each Converting Lender with a New 2013 Replacement Term Loan Commitment shall fund in cash an amount equal to its New 2013 Replacement Term Loan Commitment to the Designated Replacement Term Lender and (2) each New 2013 Replacement Term Lender shall fund in cash an amount equal to its 2013 Replacement Term Loan Commitment to the Designated Replacement Term Lender and (z) the Designated Replacement Term Lender shall fund in cash to the Borrower, on behalf of each Converting Lender and each New 2013 Replacement Term Lender, an amount equal to (1) in the case of a Converting Lender, such Converting Lender’s New 2013 Replacement Term Loan Commitment or (2) in the case of a New 2013 Replacement Term Lender, such New 2013 Replacement Term Lender’s New 2013 Replacement Term Loan Commitment.

(iv) The Converted 2013 Replacement Term Loans subject to the Term Loan Conversion shall be allocated ratably to the outstanding Borrowings of Replaced Term Loans (based upon the relative principal amounts of Borrowings of Replaced Term Loans subject to different Interest Periods immediately prior to giving effect thereto). Each resulting “borrowing” of Converted 2013 Replacement Term Loans shall constitute a “Borrowing” under the Credit Agreement and be subject to the same Interest Period (and the same LIBO Rate) applicable to the Borrowing of Replaced Term Loans to which it relates, which Interest Period shall continue in effect until such Interest Period expires and a new Type of Borrowing is selected in accordance with the provisions of Section 2.02 of the Credit Agreement. New 2013 Replacement Term Loans shall be initially incurred pursuant to “borrowings” of LIBO Rate Loans which shall be allocated ratably to the outstanding “deemed” Borrowings of Converted 2013 Replacement Term Loans on the Amendment No. 4 Effective Date (based upon the relative principal amounts of the deemed Borrowings of Converted 2013 Replacement Term Loans subject to different Interest Periods on the Amendment No. 4 Effective Date after giving effect to the foregoing provisions of this clause (iv)). Each such “borrowing” of New 2013 Replacement Term Loans shall (i) be added to (and made a part of) the related deemed Borrowing of Converted 2013 Replacement Term Loans, (ii) be subject to (x) an Interest Period which commences on the Amendment No. 4 Effective Date and ends on the last day of the Interest Period applicable to the related deemed Borrowing of Converted 2013 Replacement Term Loans to which it is added and (y) the same LIBO Rate applicable to such deemed Borrowing of Converted 2013 Replacement Term Loans.

3

(v) On the Amendment No. 4 Effective Date, the Borrower shall pay in cash (a) all interest accrued on the Replaced Term Loans through the Amendment No. 4 Effective Date and (b) to each Non-Converting Lender and each Converting Lender with a Non-Converting Portion, any breakage loss or expenses due under Section 3.05 of the Credit Agreement (it being understood that existing Interest Periods of the Replaced Term Loans held by 2013 Replacement Term Lenders prior to the Amendment No. 4 Effective Date shall continue on and after the Amendment No. 4 Effective Date pursuant to preceding clause (iv) and shall accrue interest in accordance with Section 2.08 of the Credit Agreement on and after the Amendment No. 4 Effective Date as if the Amendment No. 4 Effective Date were a new Borrowing date). Each Converting Lender hereby waives any entitlement to any breakage loss or expenses due under Section 3.05 of the Credit Agreement with respect to the repayment of the applicable portion of its Replaced Term Loans with the proceeds of Converted 2013 Replacement Term Loans.

(vi) Promptly following the Amendment No. 4 Effective Date, all Term Notes, if any, evidencing the Replaced Term Loans shall be cancelled, and any 2013 Replacement Term Lender may request that its 2013 Replacement Term Loan be evidenced by a Term Note pursuant to Section 2.11(a) of the Credit Agreement.

(vii) Notwithstanding anything to the contrary contained in the Credit Agreement, all proceeds of the New 2013 Replacement Term Loans (if any) will be used solely to repay outstanding Replaced Term Loans of Non-Converting Lenders (if any) and outstanding Replaced Term Loans of Converting Lenders in an amount equal to any Non-Converting Portion (if any) of such Converting Lenders’ Replaced Term Loans, in each case on the Amendment No. 4 Effective Date.
