WHEREAS, subject to the terms and conditions of the Credit Agreement, the Borrower may obtain additional Revolving Commitments by, among other things, entering into one or more incremental amendments with the Administrative Agent and each Lender being added or increasing its Commitment;

WHEREAS, the Borrower has notified the Administrative Agent of its desire to increase the Revolving Commitments by an aggregate principal amount equal to $175,000,000 (the "<u>2025-C Incremental Revolving Increase</u>") upon the occurrence of the Amendment Effective Time (as defined below), the proceeds of which shall be used for general corporate purposes of the Borrower and its Subsidiaries in the ordinary course of business; and

WHEREAS, each Lender signatory hereto as a "2025-C Incremental Revolving Lender" (each such Lender, a "<u>2025-C Incremental Revolving Lender</u>") has agreed to provide additional Revolving Commitments to the Borrower in the aggregate principal amount set forth opposite its name under the column entitled "2025-C Incremental Revolving Commitments" in <u>Schedule 1</u> attached hereto (the "<u>2025-C Incremental Revolving Commitments</u>") in accordance with the terms of this Amendment and the Credit Agreement and subject to the conditions set forth in <u>Section</u> <u>2</u>;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. <u>Amendments to Credit Agreement</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) <u>2025-C Incremental Revolving Increase</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Subject to the terms and conditions set forth herein and in the Credit Agreement, each 2025-C Incremental Revolving Lender hereby agrees to make Revolving Loans on a several and not joint basis with the existing Lenders in dollars to the Borrower from time to time during the Availability Period in an aggregate principal amount that will not result in (i) such Lender's Revolving Exposure exceeding such Lender's Revolving Commitment or (ii) the Aggregate Revolving Exposure exceeding the aggregate Revolving Commitment. Within the foregoing limits and subject to the terms and conditions set forth herein and in the Credit Agreement, the Borrower may borrow, prepay and reborrow Revolving Loans.

------

The 2025-C Incremental Revolving Commitments shall be in the form of an increase to the existing Revolving Commitments and shall have identical terms (including with respect to maturity) as the existing Revolving Commitments. The 2025-C Incremental Revolving Commitments shall be deemed Revolving Commitments for all purposes of the Loan Documents and each Loan made thereunder shall be deemed, for all purposes of the Loan Documents, a Revolving Loan and each 2025-C Incremental Revolving Lender shall become a Lender with respect to its 2025-C Incremental Revolving Commitments and all matters relating thereto. Each 2025-C Incremental Revolving Lender hereby assumes all rights and obligations of a "Lender" under the Loan Documents.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) Upon the occurrence of the Amendment Effective Time, (i) each 2025-C Incremental Revolving Lender shall make available to the Administrative Agent such amounts in immediately available funds as the Administrative Agent shall determine, for the benefit of the other Lenders, as being required in order to cause, after giving effect to such increase or addition and the use of such amounts to make payments to such other Lenders, each Lender's portion of the outstanding Revolving Loans of all the Lenders to equal its revised Applicable Percentage of such outstanding Revolving Loans, and the Administrative Agent shall make such other adjustments among the Lenders with respect to the Revolving Loans then outstanding and amounts of principal, interest, commitment fees and other amounts paid or payable with respect thereto as shall be necessary, in the opinion of the Administrative Agent, in order to effect such reallocation, (ii) the Borrower shall be deemed to have repaid and reborrowed all outstanding Revolving Loans as of the Amendment Effective Time (with such reborrowing to consist of the Types of Revolving Loans, with related Interest Periods if applicable, specified in a notice delivered by the Borrower, in accordance with the requirements of Section 2.03 of the Credit Agreement) and (iii) each Revolving Lender immediately prior to the Amendment Effective Time will automatically and without further act be deemed to have assigned to each 2025-C Incremental Revolving Lender, and each 2025-C Incremental Revolving Lender will automatically and without further act be deemed to have assumed a portion of such Revolving Lender's participations under the Credit Agreement in outstanding Letters of Credit such that, after giving effect to each deemed assignment and assumption of participations, all of the Revolving Lenders' (including each 2025-C Incremental Revolving Lender's) participations in Letters of Credit shall be held on a pro rata basis in accordance with their respective revised Applicable Percentages of the aggregate Letters of Credit outstanding on such date. The deemed payments made pursuant to clause (ii) of the immediately preceding sentence shall be accompanied by payment of all accrued interest on the amount prepaid and, in respect of each Term Benchmark Loan, shall be subject to indemnification by the Borrower pursuant to the provisions of Section 2.16 of the Credit Agreement if the deemed payment occurs other than on the last day of the related Interest Periods.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) The Revolving Commitments of the Lenders as of the Amendment Effective Time (after giving effect thereto) shall be as set forth on <u>Schedule 2</u> hereto (which Schedule 2 shall replace the Commitment Schedule as of the Amendment Effective Time and become part of the Credit Agreement).
