A. The Borrower has requested that the Persons set forth on Schedule I hereto (the “Additional Tranche C Term Lenders”) make Incremental Term Loans in the form of additional Tranche C Term Loans in an aggregate principal amount of $900,000,000 (the “Additional Tranche C Term Loans”) to the Borrower on the Additional Tranche C Term Loan Effective Date (as defined below).

C. The Additional Tranche C Term Lenders are willing to make the Additional Tranche C Term Loans to the Borrower on the Additional Tranche C Term Loan Effective Date on the terms set forth herein and in the Credit Agreement and subject to the conditions set forth herein.

Accordingly, in consideration of the mutual agreements herein contained and other good and valuable consideration, the sufficiency and receipt of which are hereby acknowledged, the parties hereto agree as follows:

SECTION 1. Defined Terms. Capitalized terms used but not defined herein (including in the recitals hereto) shall have the meanings given to them in the Credit Agreement (as amended hereby). The rules of interpretation set forth in Section 1.03 of the Credit Agreement are hereby incorporated by reference herein, mutatis mutandis. As used herein, the term “Additional Tranche C Transactions” means, collectively, (a) the execution, delivery and performance by each Loan Party of this Agreement, the Borrowing of the Additional Tranche C Term Loans hereunder and the use of the proceeds thereof in accordance with the terms of the Credit Agreement and this Agreement, (b) the issuance of the 2013 Senior Subordinated Notes, (c) the payment of the Specified Dividend and (d) the payment of fees and expenses incurred in connection with the foregoing (the “Transaction Costs”).

SECTION 2. Incremental Term Loan Commitments. (a) Each Additional Tranche C Term Lender hereby agrees, severally and not jointly, on the terms set forth herein and in the Credit Agreement and subject to the conditions set forth herein, to make Additional Tranche C Term Loans to the Borrower on the Additional Tranche C Term Loan Effective Date in an aggregate principal amount not to exceed the amount set forth opposite such Additional Tranche C Term Lender’s name on Schedule I hereto. Amounts borrowed under this Section 2(a) and repaid or prepaid may not be reborrowed.

(b) Unless the context shall otherwise require, the Additional Tranche C Term Loans shall constitute additional “Tranche C Term Loans”, “Incremental Term Loans”, solely with respect to the Tranche B Term Loans, “Other Term Loans” and “2013 Incremental Term Loans” and the Additional Tranche C Term Lenders shall constitute additional “Tranche C Term Lenders”, “Incremental Term Lenders” and “Lenders”, in each case for all purposes of the Credit Agreement and the other Loan Documents.

(c) The proceeds of the Additional Tranche C Term Loans shall be used solely (i) to finance a portion of the Specified Dividend and to pay the Transaction Costs and (ii) for general corporate purposes of the Borrower and its Subsidiaries, including, without limitation, Permitted Acquisitions.

(d) Unless previously terminated, the commitments of the Additional Tranche C Term Lenders pursuant to
Section 2(a) shall terminate upon the making of the Additional Tranche C Term Loans on the Additional Tranche C Term Loan Effective Date.

SECTION 8. Effect of Agreement. Except as expressly set forth herein, this Agreement shall not by implication or otherwise limit, impair, constitute a waiver of, or otherwise affect the rights and remedies of the Lenders or the Agent under the Credit Agreement or any other Loan Document, and shall not alter, modify, amend or in any way affect any of the terms, conditions, obligations, covenants or agreements contained in the Credit Agreement or any other Loan Document, all of which are ratified and affirmed in all respects and shall continue in full force and effect. Nothing herein shall be deemed to entitle any Loan Party to a consent to, or a waiver, amendment, modification or other change of, any of the terms, conditions, obligations, covenants or agreements contained in the Credit Agreement or any other Loan Document in similar or different circumstances. This Agreement shall apply and be effective only with respect to the provisions of the Credit Agreement specifically referred to herein. After the Additional Tranche C Term Loan Effective Date, any reference to the Credit Agreement in any Loan Document, and the terms “this Agreement”, “herein”, “hereunder”, “hereto”, “hereof” and words of similar import in the Credit Agreement, shall, unless the context otherwise requires, mean the Credit Agreement as modified hereby. This Agreement shall constitute a “Loan Document” and an “Incremental Term Loan Assumption Agreement”, in each case for all purposes of the Credit Agreement and the other Loan Documents.

SECTION 9. Acknowledgement and Consent. Each Loan Party hereby acknowledges that it has read this Agreement and consents to the terms hereof and further hereby affirms, confirms and agrees that (a) notwithstanding the effectiveness of this Agreement, the obligations of such Loan Party under each of the Loan Documents to which it is a party shall not be impaired and each of the Loan Documents to which such Loan Party is a party is, and shall continue to be, in full force and effect and is hereby confirmed and ratified in all respects, in each case, as amended hereby; (b) its Guarantee of the Obligations, and the pledge of and/or grant of a security interest in its assets as Collateral to secure the Obligations, all as and to the extent provided in the Collateral Documents as originally executed, shall continue in full force and effect in respect of, and to secure, the Obligations (including the Additional Tranche C Term Loans); and (c) all the representations and warranties made by or relating to it contained in the Credit Agreement and the other Loan Documents are true and correct in all material respects on and as of the Additional Tranche C Term Loan Effective Date, except to the extent such representations and warranties expressly relate to an earlier date, in which case they shall be true and correct in all material respects on and as of such earlier date; provided that, in each case, such materiality qualifier shall not be applicable to any representation and warranty that already is qualified or modified by materiality in the text thereof.

SECTION 10. Counterparts. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. Delivery of an executed counterpart of a signature page of this Agreement by facsimile or other electronic method of transmission shall be effective as delivery of a manually signed counterpart of this Agreement.
