E. NOW, THEREFORE, to induce the Administrative Agent and the Lenders to enter into this First Amendment and in consideration of the promises and the mutual covenants herein contained, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

Section 1.Defined Terms. Each capitalized term used herein but not otherwise defined herein has the meaning given such term in the Credit Agreement, as amended by this First Amendment (unless otherwise indicated). Unless otherwise indicated, all section references in this First Amendment refer to sections of the Credit Agreement.

Section 2. Amendments to Credit Agreement.

2.1 Amendment to Cover Page. The cover page of the Credit Agreement is hereby amended by replacing the reference to “SUNTRUST BANK” with “TRUIST BANK”.

2.2 Amendment to Introductory Paragraph. The introductory paragraph of the Credit Agreement is hereby amended by replacing the reference to “SunTrust Bank” with “Truist Bank”.

2.3 Amendments to Section 1.02 – Certain Defined Terms.

(a) The following definitions are hereby amended and restated in their entirety to read as follows:

“Aggregate Elected Borrowing Base Commitments” means (a) on the First Amendment Effective Date, $240,000,000 and (b) at any time thereafter, an amount determined in accordance with Section 2.07(g).

“Agreement” means this Credit Agreement, including any schedules and exhibits hereto, as amended by the First Amendment, and as the same may from time to time be amended, modified, supplemented or restated.

“Applicable Margin” means, for any day, with respect to any ABR Loan or Eurodollar Loan, or with respect to the Commitment Fee Rate, as the case may be, the rate per annum set forth in the Borrowing Base Utilization Grid below based upon the Borrowing Base Utilization Percentage then in effect:



Borrowing Base Utilization Grid
	<25%	≥25%, but <50%	≥50%, but <75%	≥75%, but <90%	≥90%
ABR Loans	1.00%	1.25%	1.50%	1.75%	2.00%
Eurodollar Loans	2.00%	2.25%	2.50%	2.75%	3.00%
Commitment Fee Rate	0.375%	0.375%	0.50%	0.50%	0.50%

Notwithstanding the foregoing, if the Consolidated Leverage Ratio for the Reference Period ending on the last day of any fiscal quarter or fiscal year, as applicable, exceeds 1.50 to 1.00, then the Applicable Margin set forth in the above grid with respect to ABR Loans and Eurodollar Loans (but, for purposes of clarity, not the Commitment Fee Rate) will, in each case, increase by 0.25% during the period from and including the first day immediately following the date the financial statements and the related compliance certificate are delivered pursuant to Section 8.01(a) or Section 8.01(b), as applicable, and Section 8.01(c) for such fiscal quarter or fiscal year, as applicable, through and including the date of delivery of the financial statements and the related compliance certificate pursuant to Section 8.01(a) or Section 8.01(b), as applicable, and Section 8.01(c) for the immediately succeeding fiscal quarter. Each change in the Applicable Margin and Commitment Fee Rate shall apply during the period commencing on the effective date of such change and ending on the date immediately preceding the effective date of the next such change; provided, however, that if at any time the Borrower fails to deliver (i) a Reserve Report pursuant to Section 8.11(a) or (ii) the financial statements and the related

compliance certificate pursuant to Section 8.01(a) or Section 8.01(b), as applicable, and Section 8.01(c), then, if so elected by the Majority Lenders, the “Applicable Margin” means the rate per annum set forth on the grid when the Borrowing Base Utilization Percentage is at its highest level.

In the event that the certified calculation of the Consolidated Leverage Ratio previously delivered pursuant to Section 8.01(c) was inaccurate (and such inaccuracy is discovered while any Commitments or Loans are outstanding), and such inaccuracy, if corrected, would have led to the application of a higher Applicable Margin for the Loans for any period (an “Applicable Period”) than the Applicable Margin applied for such Applicable Period, then, to the extent any Commitments or Loans are outstanding at such time, (i) the Borrower shall as soon as practicable deliver to the Administrative Agent the correct certified calculation of the Consolidated Leverage Ratio for such Applicable Period, (ii) the Applicable Margin shall be determined as if the level for such higher Applicable Margin were applicable for such Applicable Period, and (iii) the Borrower shall within ten (10) Business Days of written demand thereof by the Administrative Agent pay to the Administrative Agent the accrued additional interest owing as a result of such increased Applicable Margin for the Loans for such Applicable Period, which payment shall be promptly applied by the Administrative Agent in accordance with this Agreement.

“Bail-In Action” means the exercise of any Write-Down and Conversion Powers by the applicable Resolution Authority in respect of any liability of an Affected Financial Institution.

“Bail-In Legislation” means (a) with respect to any EEA Member Country implementing Article 55 of Directive 2014/59/EU of the European Parliament and of the Council of the European Union, the implementing law, regulation rule or requirement for such EEA Member Country from time to time which is described in the EU Bail-In Legislation Schedule and (b) with respect to the United Kingdom, Part I of the United Kingdom Banking Act 2009 (as amended from time to time) and any other law, regulation or rule applicable in the United Kingdom relating to the resolution of unsound or failing banks, investment firms or other financial institutions or their affiliates (other than through liquidation, administration or other insolvency proceedings).

“EBITDAX” means, for any period, Consolidated Net Income for such period plus to the extent not otherwise added to Consolidated Net Income, the aggregate amount of dividends and distributions actually paid in cash during such period to the Borrower and its Restricted Subsidiaries by (x) any Unrestricted Subsidiary or (y) any Person in which the Borrower or any Consolidated Restricted Subsidiary has an interest (which interest does not cause the net income of such other Person to be consolidated with the net income of the Borrower and the Consolidated Restricted Subsidiaries in accordance with GAAP), in the case of each of the

foregoing clauses (x) and (y), with respect to its Equity Interests, plus the following expenses or charges to the extent deducted from Consolidated Net Income in such period: the sum of (a) (i) interest expense, (ii) income taxes, franchise or similar taxes, and (iii) depreciation, depletion, amortization, exploration and abandonment expenses, (b) distributions in connection with Equity Interests owned by management employees of the Borrower and its Restricted Subsidiaries permitted under this Agreement; (c) any actual expenses or charges directly incurred in connection with any issuance of Equity Interests, Investment, acquisition, disposition, recapitalization or the incurrence or repayment of Debt permitted to be incurred hereunder (including, for the avoidance of doubt, Debt under the Loan Documents) including a refinancing thereof (whether or not successful) and any amendment or modification to the terms of any such transactions, including any Transaction Expenses, in an aggregate amount not to exceed five percent (5%) of EBITDAX (prior to giving effect thereto) for any period of four consecutive fiscal quarters of the Borrower, and provided that the Borrower has delivered to the Administrative Agent a certificate from a Financial Officer of the Borrower certifying, in good faith, as to such expenses or charges, in such detail, and together with such supporting documentation therefor, as may be reasonably requested by the Administrative Agent; (d) solely to the extent (i) covered by indemnification provisions in any agreement and (ii) actually reimbursed, expenses incurred in connection with any Disposition or other Investment permitted hereunder; (e) any extraordinary, unusual or nonrecurring expenses or losses to the extent such amounts are non-cash; and (f) all other noncash charges, minus the sum of (1) all noncash income added to Consolidated Net Income; (2) gains on asset Dispositions, disposals and abandonments outside of the ordinary course of business and (3) to the extent not otherwise deducted from Consolidated Net Income, the aggregate amount of all Pass-Through Restricted Payment Related Proceeds of Unrestricted Subsidiary Cash Distributions received by the Borrower or any Restricted Subsidiary during such period in an amount equal to the aggregate amount of Pass-Through Restricted Payments actually made by the Borrower or any Restricted Subsidiary pursuant to Pass-Through Restricted Payments during such period. For the purposes of calculating EBITDAX for any Reference Period, (i) if during such Reference Period the Borrower or any Consolidated Restricted Subsidiary shall have made any Material Disposition, EBITDAX for such Reference Period shall be reduced by an amount equal to the EBITDAX (if positive) attributable to the Property that is the subject of such Material Disposition for such Reference Period or increased by an amount equal to the EBITDAX (if negative) attributable thereto for such Reference Period, (ii) if during such Reference Period the Borrower or any Consolidated Restricted Subsidiary shall have made a Material Acquisition, EBITDAX for such Reference Period shall be calculated after giving pro forma effect thereto as if such Material Acquisition occurred on the first day of such Reference Period and (iii) if during such Reference Period a Consolidated Subsidiary shall be redesignated as either a Consolidated Unrestricted Subsidiary or a Consolidated Restricted Subsidiary, EBITDAX shall be calculated after giving pro forma effect to such redesignation, as if such redesignation had occurred on the first day of such Reference

Period. Notwithstanding anything herein to the contrary: EBITDAX for the Reference Period ending on December 31, 2019 shall be calculated by multiplying EBITDAX for the fiscal quarter ending on such date by four (4); EBITDAX for the Reference Period ending on March 31, 2020 shall be calculated by multiplying EBITDAX for the two consecutive fiscal quarters ending on such date by two (2); and EBITDAX for the Reference Period ending on June 30, 2020 shall be calculated by multiplying EBITDAX for the three consecutive fiscal quarters ending on such date by four-thirds (4/3).

“Permitted Holders” means (i) EnCap and (ii) such other Persons as the Majority Lenders shall expressly consent to in writing as “Permitted Holders”.

“Write-Down and Conversion Powers” means, (a) with respect to any EEA Resolution Authority, the write-down and conversion powers of such EEA Resolution Authority from time to time under the Bail-In Legislation for the applicable EEA Member Country, which write-down and conversion powers are described in the EU Bail-In Legislation Schedule, and (b) with respect to the United Kingdom, any powers of the applicable Resolution Authority under the Bail-In Legislation to cancel, reduce, modify or change the form of a liability of any UK Financial Institution or any contract or instrument under which that liability arises, to convert all or part of that liability into shares, securities or obligations of that person or any other person, to provide that any such contract or instrument is to have effect as if a right had been exercised under it or to suspend any obligation in respect of that liability or any of the powers under that Bail-In Legislation that are related to or ancillary to any of those powers.
