RECITALS

WHEREAS, the Borrower has entered into that certain Credit Agreement, dated as of November 1, 2012 (as amended, amended and restated, supplemented or otherwise modified from time to time, prior to the date hereto, the “Credit Agreement”), among the Borrower, the other Loan Parties party thereto, Holdings, the several banks and other financial institutions from time to time party thereto (the “Lenders”) and the Administrative Agent.

WHEREAS, pursuant to Section 2.6 of the Credit Agreement, the Borrower hereby proposes to increase the aggregate Tranche G Term Loans from $1,145,000,000 to an amount of $1,295,000,000.

WHEREAS, pursuant to and in accordance with Section 2.6 of the Existing Credit Agreement, the Borrower has requested that Supplemental Term Loan Commitments be made available to the Borrower, and the Increasing Tranche G Lender and the Administrative Agent have agreed, upon the terms and subject to the conditions set forth herein, that the Increasing Tranche G Lender will make Supplemental Term Loans in the form of the Supplemental Tranche G Term Loans in an aggregate principal amount of $150,000,000 (the entry into this Increase Supplement and the borrowing of Supplemental Tranche G Term Loans hereunder, and any or all of the foregoing transactions referred to in this paragraph, collectively, the “Transactions”); and

WHEREAS, JPMorgan Chase Bank, N.A. (the “Arranger”) is acting as sole lead arranger and sole bookrunner for the Supplemental Tranche G Term Loans.

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

Section 1.    Defined Terms: As used in this Increase Supplement, the following terms shall have the following meanings:

(a)    “Increasing Tranche G Lender”: the financial institution party hereto, as set forth on the signature pages hereof.

(b)     “Supplemental Tranche G Commitment”: as to the Increasing Tranche G Lender, its obligation to make Supplemental Tranche G Term Loans to the Borrower pursuant to Section 2 in an aggregate amount not to exceed the amount set forth in Annex I attached hereto opposite the name of such Increasing Tranche G Lender. The original aggregate amount of the Supplemental Tranche G Commitments on the Third Increase Supplement Effective Date is $150,000,000.

Section 2.    Supplemental Term Loans:

(a)    Subject to the conditions set forth in Section 4 and in accordance with the terms hereof, the Increasing Tranche G Lender agrees to make, in Dollars, in a single draw, a term loan (each such term loan, a “Supplemental Tranche G Term Loan”) to the Borrower in an aggregate principal amount not to exceed its Supplemental Tranche G Commitment as such amount may be adjusted or reduced pursuant to the terms hereof. Each Supplemental Tranche G Term Loan shall, except as set forth herein, be, and be subject to the provisions applicable to, Tranche G Term Loans for all purposes of the Credit Agreement and the other Loan Documents: For the avoidance of doubt, the Supplemental Tranche G Term Loans shall be considered an increase in the Tranche G Term Loans and shall not be considered a separate Tranche of Tranche G Term Loans under the Credit Agreement.

(b)    The Increasing Tranche G Lender will make an amount equal to its pro rata share of the Supplemental Tranche G Term Loans available to the Administrative Agent for the account of the Borrower at the office of the Administrative Agent specified in Section 11.2 of the Credit Agreement prior to 10:00 A.M., New York City time, on the Third Increase Supplement Effective Date in funds immediately available to the Administrative Agent. The Administrative Agent shall on such date credit the account of the Borrower on the books of the Administrative Agent with the aggregate of the amounts made available to the Administrative Agent by the Lenders and in like funds as received by the Administrative Agent.

(c)    Unless the Administrative Agent shall have been notified in writing by any Lender prior to a borrowing that such Lender will not make the amount that would constitute its share of such borrowing available to the Administrative Agent, the Administrative Agent may assume that such Lender is making such amount available to the Administrative Agent, and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower in respect of such borrowing a corresponding amount. If such amount is not made available to the Administrative Agent by the required time on the Third Increase Supplement Effective Date, such Lender shall pay to the Administrative Agent on demand, such amount with interest thereon at a rate equal to the daily average Federal Funds Effective Rate for the period until such Lender makes such amount immediately available to the Administrative Agent. A certificate of the Administrative Agent submitted to any Lender with respect to any amounts owing under this Section 2(c) shall be conclusive in the absence of manifest error.

(d)    On the Third Increase Supplement Effective Date, the Supplemental Tranche G Term Loans incurred on such date that are SOFR Loans shall be allocated to the then outstanding Borrowings of SOFR Loans and the Supplemental Tranche G Term Loans incurred on such date that are ABR Loans shall be allocated to the then outstanding Borrowings of ABR Loans, with the effect that: (A) the Supplemental Tranche G Term Loans allocated to SOFR Loans shall be added to (and thereafter be deemed to constitute a part of)

2

such SOFR Loans, with an Interest Period that ends on the same date as the Interest Period for such SOFR Loans to which they are added and (B) the Supplemental Tranche G Term Loans allocated to ABR Loans shall be added to (and thereafter be deemed to constitute part of) such ABR Loans, and be subject to the same Alternate Base Rate as such ABR Loans to which they are added. The Administrative Agent shall (and is hereby authorized to) take all appropriate actions in connection with the incurrence of Supplemental Tranche G Term Loans on the Third Increase Supplement Effective Date to ensure that the Supplemental Tranche G Term Loans are treated in the manner contemplated by this Section 2(d).

Section 3.    [Reserved].
