Senior Revolving Credit Facility

On the Effective Date, the Company entered into a senior secured revolving credit agreement, as amended, (the Senior Credit Agreement) with Bank of Montreal, as administrative agent, and certain other financial institutions party thereto, as lenders, which refinanced the Predecessor Company’s Amended and Restated Senior Secured Revolving Credit Agreement (the Predecessor Credit Agreement). The Senior Credit Agreement provides for a $750.0 million senior secured reserve‑based revolving credit facility with a current borrowing base of $200.0 million. At March 31, 2020 (Successor), the Company had $170.0 million indebtedness outstanding and approximately $4.4 million letters of credit outstanding. Under the current borrowing base of $200.0 million, the Company would have approximately $25.6 million of borrowing capacity available under the Senior Credit Agreement as of March 31, 2020 (Successor).

A portion of the Senior Credit Agreement, in the amount of $50.0 million, is available for the issuance of letters of credit. The maturity date of the Senior Credit Agreement is October 8, 2024. Redeterminations will occur semi-annually on May 1 and November 1, with the lenders and the Company each having the right to one interim unscheduled redetermination between any two consecutive semi-annual redeterminations. The borrowing base takes into account the estimated value of the Company’s oil and natural gas properties, proved reserves, total indebtedness, and other relevant factors consistent with customary oil and natural gas lending criteria. Amounts outstanding under the Senior Credit Agreement bear interest at specified margins over the base rate of 1.50% to 2.50% for ABR-based loans or at specified margins over LIBOR of 2.50% to 3.50% for Eurodollar-based loans, which margins may be increased one-time by not more than 50 basis points per annum if necessary in order to successfully syndicate the Senior Credit Agreement. These margins fluctuate based on the Company’s utilization of the facility.

The Company may elect, at its option, to prepay any borrowings outstanding under the Senior Credit Agreement without premium or penalty, except with respect to any break funding payments which may be payable pursuant to the terms of the Senior Credit Agreement. The Company may be required to make mandatory prepayments of the outstanding borrowings under the Senior Credit Agreement in connection with certain borrowing base deficiencies, including deficiencies which may arise in connection with a borrowing base redetermination, an asset disposition or swap terminations attributable in the aggregate to more than ten percent (10%) of the then-effective borrowing base. Amounts outstanding under the Senior Credit Agreement are guaranteed by the Company’s direct and indirect subsidiaries and secured by a security interest in substantially all of the assets of the Company and its subsidiaries.

The Senior Credit Agreement contains certain events of default, including non-payment; breaches of representation and warranties; non-compliance with covenants; cross-defaults to material indebtedness; voluntary or involuntary bankruptcy; judgments and change in control. The Senior Credit Agreement also contains certain financial covenants, including maintenance of (i) a Total Net Indebtedness Leverage Ratio (as defined in the Senior Credit Agreement) of not greater than 3.50 to 1.00 and (ii) a Current Ratio (as defined in the Senior Credit Agreement) of not less than 1.00 to 1.00, both commencing with the fiscal quarter ending March 31, 2020. As of March 31, 2020 (Successor), the Company was in compliance with the financial covenants under the Senior Credit Agreement.

On April 30, 2020 (Successor), the Company entered into the Second Amendment to the Senior Credit Agreement (Second Amendment) which among other things, (i) reduced the borrowing base to $200.0 million effective from April 30, 2020, which shall then be reduced by $5.0 million monthly starting September 1, 2020 until November 1, 2020, so that the borrowing base is scheduled to be $185.0 million on November 1, 2020, provided the borrowing base redetermination scheduled for November 1, 2020 shall occur pursuant to the terms of the Senior Credit Agreement, (ii) increased interest margins to 1.50% to 2.50% for ABR-based loans and 2.50% to 3.50% for Eurodollar-based loans, (iii) provided that should the Company’s Consolidated Cash Balance (as defined pursuant to the Second Amendment) exceed $10.0 million, such amounts shall be used to prepay any borrowings under the Senior Credit Agreement and thereafter, to the extent of any uncollateralized letters of credit exposure, shall be cash collateralized in accordance with the Senior Credit Agreement and (iv) allowed for a replacement benchmark rate to the London Interbank Offered Rate (which may include SOFR, Compounded SOFR or Term SOFR).

The Second Amendment also added provisions related a loan (PPP Loan) incurred by the Company from the U.S. Small Business Administration, under the Paycheck Protection Program (PPP) of the Coronavirus Aid, Relief, and Economic Security Act (the CARES Act). Under the terms of the CARES Act, PPP Loan recipients can apply for and be granted forgiveness for all or a portion of loans granted under the PPP. Such forgiveness will be determined, subject to limitations, based on the use of loan proceeds for payment of payroll costs and any payments of mortgage interest, rent, and utilities. The Company intends to use, and the Second Amendment requires the Company to use, the PPP Loan proceeds for CARES Forgivable Uses under the CARES Act.

Additionally, the Second Amendment waived, for the fiscal quarter ended June 30, 2020, that the Company comply with the requirement under the Senior Credit Agreement that the Company unwind certain swap agreements for which settlement payments are calculated in such fiscal quarter to exceed 100% of actual production.

On November 21, 2019 (Successor), the Company entered into the First Amendment to the Senior Credit Agreement which, among other things, (i) reduced the borrowing base to $240.0 million and (ii) limited the Total Net Indebtedness Leverage Ratio (as defined in the Senior Credit Agreement) as of the last day of each fiscal quarter, commencing with the fiscal quarter ending March 31, 2020, of not greater than 3.50 to 1.00.
