B.Borrower, Parent, Administrative Agent and Lenders party hereto desire to modify certain provisions contained in the Credit Agreement, in each case subject to the terms and conditions set forth herein.

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

1.Terms and References. Unless otherwise stated in this Amendment (a) terms defined in the Credit Agreement have the same meanings when used in this Amendment, and (b) references to “Sections” are to the Credit Agreement’s sections.

2.Amendments to the Credit Agreement.

(a)Section 1.01 of the Credit Agreement is hereby amended to add the following definition in the appropriate alphabetical order:

“Fourth Amendment Effective Date” means January 16, 2018, the effective date of the Fourth Amendment to Credit Agreement, executed by Borrower, Parent, Administrative Agent and Lenders.

(b)Section 1.01 of the Credit Agreement is hereby amended to delete the definition of “Applicable Margin” in its entirety and replace such definition with the following:

“Applicable Margin” means:

(a)Subject to clause (b) below, the following percentages per annum, based upon the Leverage Ratio as set forth in the most-recent Compliance Certificate received by Administrative Agent pursuant to Section 8.02(a):

Any increase or decrease in the Applicable Margin resulting from a change in the Leverage Ratio shall become effective as of the first (1^st) Business Day immediately following the date a Compliance Certificate is delivered pursuant to Section 8.02(a); provided that if a Compliance Certificate is not delivered when due in accordance with such Section, then, upon the request of Required Lenders, Pricing Level 6 shall apply as of the first (1^st) Business Day after the date on which such Compliance Certificate was required to have been delivered and shall remain in effect until the date on which such Compliance Certificate is delivered. The Applicable Margin in effect from the Fourth Amendment Effective Date until adjusted as set forth above shall be set at Pricing Level 1.

Notwithstanding anything to the contrary contained in this clause (a), the determination of the Applicable Margin under this clause (a) for any period shall be subject to the provisions of Section 2.08(b).

(b)If Parent or Borrower obtains an Investment Grade Rating, Borrower may, upon written notice to Administrative Agent, make an irrevocable one time written election to exclusively use the below table based on the Debt Rating of Parent or Borrower (setting forth the date for such election to be effective), and thereafter the Applicable Margin shall be determined based on the applicable rate per annum set forth in the below table notwithstanding any failure of Parent or Borrower to maintain an Investment Grade Rating or any failure of Parent or Borrower to maintain a Debt Rating:

If at any time Parent and/or Borrower has only two (2) Debt Ratings, and such Debt Ratings are split, then: (a) if the difference between such Debt Ratings is one ratings category (e.g., Baa2 by Moody’s and BBB- by S&P or Fitch), the ratings-based Applicable Margin shall be the rate per annum that would be applicable if the higher of the Debt Ratings were used; and (b) if the difference between such Debt Ratings is two (2) ratings categories (e.g., Baa1 by Moody’s and BBB- by S&P), the ratings-based Applicable Margin shall be the rate per annum that would be applicable if the rating that is one higher than the lower of the applicable Debt Ratings were used. If at any time Parent and/or Borrower has three (3)

Debt Ratings, and such Debt Ratings are split, then: (i) if the difference between the highest and the lowest such Debt Ratings is one ratings category (e.g., Baa2 by Moody’s and BBB- by S&P or Fitch), the ratings-based Applicable Margin shall be the rate per annum that would be applicable if the highest of the Debt Ratings were used; and (ii) if the difference between such Debt Ratings is two (2) ratings categories (e.g., Baa1 by Moody’s and BBB- by S&P or Fitch) or more, the ratings-based Applicable Margin shall be the rate per annum that would be applicable if the average of the two (2) highest Debt Ratings were used, provided that if such average is not a recognized rating category, then the ratings-based Applicable Margin shall be the rate per annum that would be applicable if the second highest Debt Rating of the three (3) were used.

3.Amendments to other Loan Documents.

(a)All references in the Loan Documents to the Credit Agreement shall henceforth include references to the Credit Agreement, as modified and amended hereby, and as may, from time to time, be further amended, modified, extended, renewed, and/or increased.
