The A&R Credit Agreement amends and restates in its entirety the Senior Secured Revolving Credit Agreement entered into on September 9, 2016 (as amended, the “Original Credit Agreement”). Pursuant to the A&R Credit Agreement, the lenders party thereto have agreed to provide the Company with a $140.0 million senior secured reserve-based revolving credit facility (the “Credit Facility” and the loans thereunder, the “Loans”).

Until such maturity date, the Loans under the A&R Credit Agreement shall bear interest at a rate per annum equal to (i) the alternative base rate plus an applicable margin of 1.25% to 2.25%, based on the borrowing base utilization percentage under the Credit Facility or (ii) adjusted LIBOR plus an applicable margin of 2.25% to 3.25%, based on the borrowing base utilization percentage under the Credit Facility.

The Company may elect, at its option, to prepay any borrowing outstanding under the A&R Credit Agreement without premium or penalty (except with respect to any break funding payments, which may be payable pursuant to the terms of the A&R Credit Agreement). The Company may be required to make mandatory prepayments of the Loans under the Credit Facility in connection with certain borrowing base deficiencies.

Amounts outstanding under the A&R Credit Agreement are guaranteed by certain of the Company’s direct and indirect subsidiaries and secured by a security interest in substantially all of the assets of the Company and such direct and indirect subsidiaries.

The A&R Credit Agreement contains certain customary representations and warranties, including organization; powers; authority; enforceability; approvals; no conflicts; financial condition; no material adverse effect; litigation; environmental matters; compliance with laws; no defaults; Investment Company Act; taxes; ERISA; disclosure; no material misstatements; properties and titles; maintenance of properties; gas imbalances; prepayments; marketing of production; swap agreements; use of proceeds; solvency; money laundering; anti-corruption laws and sanctions.

The A&R Credit Agreement also contains certain financial covenants, including the maintenance of (i) a ratio of Consolidated Total Net Debt (as defined in the A&R Credit Agreement) to EBITDA not to exceed 4.00:1.00, and (ii) a Current Ratio (as defined in the A&R Credit Agreement) not to be less than 1.00:1.00, each determined as of the last day of any fiscal quarter period.

The A&R Credit Agreement also contains certain events of default, including non-payment; breaches of representations and warranties; non-compliance with covenants or other agreements; cross-default to material indebtedness; judgments; change of control; and voluntary and involuntary bankruptcy.
