NOW, THEREFORE, in consideration of the premises and for other good and valuable consideration (the receipt and sufficiency of which is hereby acknowledged), the parties hereto hereby agree as follows:

Section 1.     Amendments to the Credit Agreement

The Credit Agreement is, effective as of the Amendment No. 8 Effective Date, hereby amended to:

(a)remove Schedule 1.1A (Revolving Commitment Amounts) and replace it in its entirety by new Schedule 1.1A attached hereto as Exhibit C;

(b)add the following definitions in alphabetical order to Section 1.1 (Defined Terms):

“Amendment No. 8 Effective Date”: means May 18, 2018.

“Beneficial Ownership Certification” means a certification regarding beneficial ownership required by the Beneficial Ownership Regulation, which certification shall be

-2-

substantially similar in form and substance to the form of Certification Regarding Beneficial Owners of Legal Entity Customers published jointly, in May 2018, by the Loan Syndications and Trading Association and Securities Industry and Financial Markets Association.

“Beneficial Ownership Regulation” means 31 C.F.R. § 1010.230.

(c)remove the definition of “Class C Revolving Commitment” and replace it in its entirety with the below:

“Class C Revolving Commitment”: with respect to each Class C Lender, the obligation of such Class C Lender, if any, to make Class C Revolving Loans and participate in Swingline Loans and Letters of Credit in an aggregate principal and/or face amount not to exceed the amount set forth opposite its name on Schedule 1.1A hereto under the heading “Class C Revolving Commitment Amounts” or as may subsequently be set forth in the Register from time to time, as the same may be (x) reduced from time to time pursuant to Sections 2.12 and 2.14 or (y) increased from time to time pursuant to Section 2.25. The aggregate Class C Revolving Commitments of all Class C Lenders shall be $1,519,200,000 on the Amendment No. 8 Effective Date, as such amount may be adjusted from time to time in accordance with the terms of this Agreement.

(d)remove the definition of “Total Revolving Commitments” and replace it in its entirety with the below:

“Total Revolving Commitments”: at any time, the aggregate amount of the Revolving Commitments then in effect. The Total Revolving Commitments on the Amendment No. 8 Effective Date are $1,689,200,000.

(e)Add the following as Section 3.21 thereof:

“3.21.Beneficial Ownership Certification. As of the Amendment No. 8 Effective Date, the information included in the Beneficial Ownership Certification is true and correct in all respects.”

Section 2.     Consent to the New Revolving Lender and the Integral Multiple Consent.

(a)The Administrative Agent, the Fronting Banks and the Borrower hereby consent to the New Revolving Lender becoming a “Lender” and providing Class C Revolving Commitments under the Credit Agreement as amended hereby.

(b)The Administrative Agent, the Borrower and the Existing Lenders party hereto constituting the Required Lenders hereby consent to the Integral Multiple Consent.

Section 3.     New Revolving Commitments. The New Revolving Lender has agreed (on a several and not joint basis), subject to the terms and conditions set forth herein and in the Credit Agreement, as amended by this Amendment, to provide the New Revolving Lender

-3-

Commitment in the amount set forth opposite its name on Exhibit B hereto. Each Increasing Revolving Lender has agreed (on a several and not joint basis), subject to the terms and conditions set forth herein and in the Credit Agreement, as amended by this Amendment, to increase its Class C Revolving Commitment in the amount set forth opposite such Increasing Revolving Lender’s name on Exhibit A hereto and that from and after the Amendment No. 8 Effective Date its aggregate Class C Revolving Commitment shall be in the amounts set forth opposite such Increasing Revolving Lender’s name on Exhibit C hereto. For the avoidance of doubt, the aggregate principal amount of Incremental Revolving Facilities provided to the Borrower on the Amendment No. 8 Effective Date shall be $219,200,000 and this Amendment shall reduce the aggregate amount of Incremental Revolving Facilities permitted to be obtained pursuant to Section 2.25 of the Credit Agreement from $500,000,000 to $280,800,000.

Section 4.     Reallocation. On the Amendment No. 8 Effective Date, the Borrower shall, in coordination with the Administrative Agent, repay outstanding Revolving Loans of the Existing Lenders that are not Increasing Revolving Lenders, and incur additional Revolving Loans from the Increasing Revolving Lenders and the New Revolving Lender to the extent necessary so that all of the Lenders participate in each outstanding Borrowing of Revolving Loans pro rata on the basis of their respective Revolving Commitments (after giving effect to any increase in the Total Revolving Commitments pursuant to this Amendment). The participations in any outstanding Letters of Credit shall be adjusted in accordance with each Lender's Revolving Commitment Percentage as reallocated in accordance with such increase of the Total Revolving Commitments.
