RECITALS

WHEREAS, the Borrower, the Guarantors from time to time party thereto, the Lenders from time to time party thereto and the Administrative Agent entered into that certain Credit Agreement, dated as of August 1, 2023 (as amended, restated, modified, supplemented or extended from time to time prior to the First Amendment Effective Date, the “Credit Agreement”);

WHEREAS, the Borrower has requested an increase of $50,000,000 in the Aggregate Revolving Commitments (the “Additional Revolving Commitments”), and the Increasing Lenders (as defined below) have agreed to provide such Additional Revolving Commitments on the terms, and subject to the conditions, set forth in this Amendment;

WHEREAS, the Borrower has requested that the Lenders amend the Credit Agreement to give effect to the Additional Revolving Commitments and to make certain other modifications to the terms and provisions thereof, as more particularly described in Section 3 below; and

WHEREAS, the Lenders have agreed to make such amendments and other modifications to the terms and provisions of the Credit Agreement, on the terms, and subject to the conditions, set forth in this Amendment;

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

1. Introductory Paragraph and Recitals; Definitions. The above introductory paragraph and recitals of this Amendment are incorporated herein by reference as if fully set forth herein. All capitalized terms used herein and not otherwise defined herein shall have the meanings given to such terms in the Credit Agreement (as amended by this Amendment or as in effect immediately prior to the effectiveness of this Amendment, as the context may require).

2. Additional Revolving Commitments and Master Reallocation.

(a) The Lenders identified on Schedule A attached hereto (such Lenders, the “Increasing Lenders”) agree to provide the Additional Revolving Commitments on the First Amendment Effective Date such that (x) each Increasing Lender’s Additional Revolving Commitment shall be the amount set forth opposite such Lender’s name on Schedule A attached hereto and (y) each Lender’s Revolving Commitment after giving effect to this Amendment shall be the amount set forth opposite such Lender’s name on Schedule 2.01 attached hereto. For the avoidance of doubt, and notwithstanding anything to the contrary contained herein or in the Credit Agreement, (i) the Additional Revolving Commitments shall be deemed to be “Revolving Commitments” as defined in the Credit Agreement for all purposes of the Credit Agreement and the other Loan Documents, having the same terms and provisions as those applicable to the

existing Revolving Commitments and (ii) the Additional Revolving Commitments shall not constitute “Incremental Revolving Commitments” as defined in the Credit Agreement. Upon the effectiveness of this Amendment, the amount of the Aggregate Revolving Commitments shall be $100,000,000.

(b) After giving effect to this Amendment, the Revolving Commitment of each Lender shall be deemed to be as set forth on Schedule 2.01 attached hereto, with a reallocation of Revolving Loans outstanding under the Revolving Commitments as they existed immediately prior to the First Amendment Effective Date occurring automatically to the extent necessary such that, after giving effect to such reallocation, each Lender will hold its Applicable Percentage of the outstanding Revolving Loans. The parties hereto agree that the Loan Parties, the Lenders and the Administrative Agent shall give effect to such reallocations, if any, pursuant to the terms of this Amendment without the necessity of any Assignment and Assumption or any other action of any Person to effectuate such reallocation. Each Lender with a Revolving Commitment agrees to make such Revolving Loans as may be requested by the Administrative Agent to give effect to the reallocation, if any, under this clause (b). For the avoidance of doubt, all assignments made pursuant to this clause (b), if any, shall not be subject to the requirements set forth in Section 11.06 of the Credit Agreement.

(c) To the extent that any transaction contemplated by Section 2 of this Amendment would require (i) delivery by the Borrower of a Loan Notice pursuant to Section 2.02(a) of the Credit Agreement or a Notice of Loan Prepayment pursuant to Section 2.05(a)(i) of the Credit Agreement, (ii) compliance with the minimum amounts set forth in Section 2.02(a) of the Credit Agreement and/or (iii) compliance with the timing requirements set forth in Section 2.02(a) of the Credit Agreement, the Administrative Agent and the Lenders hereby waive all such requirements. This waiver is a one-time waiver and shall not be construed to be a waiver of, or in any way obligate the Administrative Agent or any Lender to waive, Section 2.02(a) or 2.05(a)(i) of the Credit Agreement in any other circumstance.

(d) Each Lender hereby waives the application of Section 3.05 of the Credit Agreement with respect to any prepayment (or deemed prepayment) that occurs in connection with the reallocation contemplated by Section 2(b) to occur on the First Amendment Effective Date. This waiver is a one-time waiver and shall not be construed to be a waiver of, or in any way obligate any Lender to waive, compensation otherwise payable to such Lender under Section 3.05 of the Credit Agreement in any other circumstance.

(e) With respect to any Revolving Loan that is outstanding immediately prior to the effectiveness of this Amendment and is a Term SOFR Loan, to the extent any new Revolving Loan is made or deemed made on the First Amendment Effective Date as a result of the operation of this Section 2, such new Revolving Loan shall be made as a Term SOFR Loan with an interest period ending on the same date as the last day of the interest period of such outstanding Term SOFR Loan as in effect immediately prior to giving effect to this Amendment.
