NOW THEREFORE, for and in consideration of the mutual covenants and agreements herein contained and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged and confessed, the Borrower, the Guarantors (including, to the extent applicable, in its capacity as a counterparty to a Swap Agreement with a Secured Swap Provider), the Administrative Agent, the Issuing Bank, the Lenders party hereto and the Secured Swap Providers party hereto hereby agree as follows:

SECTION 1. Amendments to Forbearance Agreement. In reliance on the representations, warranties, covenants and agreements contained in this First Amendment, and subject to the satisfaction of the conditions precedent set forth in Section 3(a) hereof, the Forbearance Agreement is hereby amended effective as of the First Amendment Effective Date in the manner provided in this Section 1.

(b) [Reserved.]”

SECTION 2. Agreements Regarding Swap Agreements. In reliance on the representations, warranties, covenants and agreements contained in this First Amendment, and subject to the satisfaction of the conditions precedent set forth in Section 3(b) hereof:

(b) if the aggregate amount of such net cash proceeds received by the Administrative Agent in accordance with the foregoing Sections 2.1 and 2.2 is in excess of the amount applied as a principal payment in respect of the Loans pursuant to Section 2.3(a), the Administrative Agent shall promptly (but not later than August 3, 2020) pay such excess amounts to the Borrower.

2.4 No Automatic Borrowing Base Reduction. Notwithstanding anything in the Credit Agreement to the contrary, the Borrower and the Required Lenders agree that the termination of all of the Credit Parties’ Swap Agreements in existence on July 15, 2020 in accordance with Section 6.1(a) of the Forbearance Agreement (as amended hereby) shall not result in an automatic reduction of the Borrowing Base, and the Required Lenders hereby consent to the termination of such Swap Agreements in accordance with Section 6.1(a) of the Forbearance Agreement (as amended hereby).
