NOW, THEREFORE, in consideration of the premises and agreements, provisions and covenants herein contained, the parties hereto agree as follows:

(b)

The definition of “Applicable Margin” is hereby amended and restated in its entirety as follows:

“ “Applicable Margin” means a percentage per annum equal to (i) for Tranche B-1 Term Loans that are Eurodollar Loans, 3.50% and (ii) for Tranche B-1 Term Loans that are Base Rate Loans, 2.50%.”.

(c)

The definition of “Term Lender” is hereby amended and restated and replaced in its entirety with the following:

“ “Term Lender” means, collectively, prior to the Amendment No. 1 Effective Date, each Lender identified on Schedule 2.01 as having a Term Commitment on the Closing Date, the “Tranche B-1 Lenders” under Amendment No. 1, and each Eligible Assignee which acquires a Term Loan pursuant to Section 10.06(b) and their respective permitted successors, in each case, other than any such Person that has ceased to be a party hereto pursuant to an Assignment and Assumption.”.

(d)

The definition of “Term Loans” is amended by adding the following proviso at the end thereof:

“; provided that from and after the effectiveness of Amendment No. 1, “Term Loans” shall mean all Tranche B-1 Term Loans made on the Amendment No. 1 Effective Date (through exchange or otherwise) pursuant to Amendment No. 1.”.

The aggregate principal amount of Tranche B-1 Commitments as of the Amendment No. 1 Effective Date for all Lenders is $730,000,000. The Borrower may make only one borrowing under the Tranche B-1 Commitments, which shall be on the Amendment No. 1 Effective Date. Each Lender’s Tranche B-1 Commitment shall terminate immediately and without further action on the Amendment No. 1 Effective Date after giving effect to the funding of such Lender’s Tranche B-1 Commitment on such date.”.

(f)

Section 2.07 of the Credit Agreement is amended by (x) deleting the word “original” appearing before the text “aggregate principal amount” and (y) replacing the text “Closing Date” with the text “Amendment No. 1 Effective Date”, in each case, appearing therein.

(g)

Section 2.08(f) of the Credit Agreement is amended by replacing the text “Closing Date” with the text “Amendment No. 1 Effective Date”.

3.

Tranche B-1 Term Loans. Subject to the terms and conditions set forth herein, each Tranche B-1 Lender severally agrees to exchange Existing Loans for Tranche B-1 Term Loans and/or make Tranche B-1 Term Loans to the Borrower in a single borrowing in Dollars on the Amendment No. 1 Effective Date. The Tranche B-1 Term Loans shall be subject to the following terms and conditions:

(a)

Terms Generally. Other than as set forth herein, for all purposes under the Credit Agreement and the other Loan Documents, the Tranche B-1 Term Loans shall have the same terms as the Initial Term Loans and shall be treated for purposes of voluntary and mandatory prepayments (including for scheduled principal payments) and all other terms as Initial Term Loans.

(b)

Proposed Borrowing. This Agreement represents a request by the Borrower to borrow Tranche B-1 Term Loans from the Tranche B-1 Lenders as set forth on the applicable Notice of Borrowing to be delivered by the Borrower under the Credit Agreement.

(c)

New Lenders. Each New Lender (i) confirms that it has received a copy of the Credit Agreement and the other Loan Documents and the exhibits and schedules thereto, together with copies of the financial statements referred to therein and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into this Agreement; (ii) agrees that it will, independently and without reliance upon the Administrative Agent, the Collateral Agent, or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under the Credit Agreement; (iii) appoints and authorizes the Administrative Agent and the Collateral Agent to take such action as agent on its behalf and to exercise such powers under the Credit Agreement and the other Loan Documents as are delegated to the Administrative Agent or the Collateral Agent, as the case may be, by the terms thereof, together with such powers as are reasonably incidental thereto; and (iv) agrees that it will perform in accordance with their terms all of the obligations which by the terms of the Credit Agreement are required to be performed by it as a Lender, as the case may be. Each New Lender acknowledges and agrees that it shall become a “Lender” under, and for all purposes of, the Credit Agreement and the other Loan Documents, and shall be subject to and bound by the terms thereof, and shall have all rights of a Lender thereunder.

(d)

Credit Agreement Governs. Except as set forth in this Agreement, the Tranche B-1 Term Loans shall otherwise be subject to the provisions of the Credit Agreement and the other Loan Documents.

(e)

Exchange Mechanics.

(i)

On the Amendment No. 1 Effective Date, upon the satisfaction or waiver of the conditions set forth in Section 4 hereof, the outstanding amount of Existing Loans of each Converting Lender exchanged pursuant to this Agreement shall be deemed to be exchanged for an equal outstanding amount of Tranche B-1 Term Loans under the Credit Agreement. Such exchange shall be effected by book entry in such manner, and with such supporting documentation, as may be reasonably determined by the Administrative Agent in its sole discretion. It is acknowledged and agreed that each Converting Lender has agreed to accept as satisfaction in full of its right to receive payment on the outstanding amount of Existing Loans of such Converting Lender the conversion of its Existing Loans into Tranche B-1 Term Loans in accordance herewith, in lieu of the prepayment amount that would otherwise be payable by the Borrower pursuant to the Credit Agreement in respect of the outstanding amount of Existing Loans of such Converting Lender. Notwithstanding anything to the contrary herein, each Converting Lender hereby waives any break funding payments in respect of such Lender’s Initial Term Loans.

(ii)

To the extent there exist any Reallocated Loans, (x) on the Amendment No. 1 Effective Date, the Fronting Bank shall provide such Reallocated Loans to the Borrower in the amount set forth opposite the Fronting Bank’s name on Annex I hereto by purchase of Existing Loans in such amount and exchange for Tranche B-1 Term Loans on a cashless settlement basis and (y) promptly following the Amendment No. 1 Effective Date (but not later than 30 days following the Amendment No. 1 Effective Date (or such later date as may be agreed to by the Fronting Bank in its sole discretion)), each New Lender, each Non-Converting Lender and each Existing Lender purchasing additional Tranche B-1 Term Loans shall purchase Reallocated Loans from the Fronting Bank as directed by the Lead Arrangers in accordance with such Participating Lender’s Tranche B-1 Participation Notice and as allocated by the Lead Arrangers.
