RECITALS

WHEREAS, the Borrower, Holdings, the lenders from time to time party thereto (the “Lenders”), the Administrative Agent, the Issuing Lenders and the other parties from time to time party thereto, are party to the Third Amended and Restated Credit Agreement, dated as of October 14, 2021 (as amended, modified, extended, restated, replaced, or supplemented from time to time prior to the date hereof, the “Existing Credit Agreement” and, as amended hereby and as may be further amended, modified, extended, restated, replaced, or supplemented from time to time, the “Credit Agreement”); and

WHEREAS, the Borrower, Holdings, the Administrative Agent and each Lender desire to make certain modifications to the Credit Agreement;

WHEREAS, the Borrower has provided the necessary reserve report information (the “Fall 2022 Redetermination Reserve Report”) for the Administrative Agent and the Lenders to complete the fall 2022 Scheduled Redetermination of the Borrowing Base and, after reviewing such reserve information, the Administrative Agent and the requisite Lenders have recommended reaffirming the Borrowing Base at $1,000,000,000;

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:

Both Holdings and the Borrower, on the one hand, and the Administrative Agent and the Lenders party hereto, on the other hand, agree that the reaffirmation of the Borrowing Base pursuant to this Section 2 shall constitute the regularly Scheduled Redetermination of the Borrowing Base for the fall of 2022 (and not an interim redetermination of the Borrowing Base) pursuant to Section 2.07 of the Credit Agreement.
