A.    The Borrower, the Administrative Agent and the Lenders are parties to that certain First Amended and Restated Senior Secured Revolving Credit Agreement dated as of April 19, 2017 (the “Credit Agreement”), pursuant to which the Lenders have made certain credit available to and on behalf of the Borrower.

C.    The Borrower has requested, and the Administrative Agent and the Lenders have agreed subject to the terms and conditions herein to (a) increase the Borrowing Base to $370.0 million in connection with the Current Scheduled Redetermination (as defined below), (b) amend certain provisions of the Credit Agreement and (c) without prejudice to the other rights of the Administrative Agent and the Lenders under the Credit Agreement, (i) waive the application of Section 2.08(c) of the Credit Agreement in respect of the Proposed Debt Incurrence (the “Requested Borrowing Base Waiver”) and (ii) in lieu of a reduction to the Borrowing Base pursuant to Section 2.08(c) of the Credit Agreement upon the Proposed Debt Incurrence, reduce the Borrowing Base by $40.0 million upon the Proposed Debt Incurrence (the “Requested Alternative Borrowing Base Adjustment”).

D.    NOW, THEREFORE, in consideration of the premises 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 to such term in the Credit Agreement. Unless otherwise indicated, all section references in this Amendment refer to sections in the Credit Agreement.

Section 2.    Amendments to Credit Agreement.

2.1    Amendments to Section 1.02.

(a)The following defined terms are hereby inserted in the Credit Agreement where alphabetically appropriate:

“NYFRB Rate” means, for any day, the greater of (a) the Federal Funds Effective Rate in effect on such day and (b) the Overnight Bank Funding Rate in effect on such day (or for any day that is not a Banking Day, for the immediately preceding Banking Day); provided that if none of such rates are published for any day that is a Business Day, the term “NYFRB Rate” means the rate for a federal funds transaction quoted at 11:00 a.m. on such day received to the Administrative Agent from a Federal funds broker of recognized standing selected by it; provided, further, that if any of the aforesaid rates shall be less than zero, such rate shall be deemed to be zero for purposes of this Agreement.

“Overnight Funding Rate” means, for any day, the rate comprised of both overnight federal funds and overnight Eurodollar borrowings by U.S.-managed banking offices of depository institutions, as such composite rate shall be determined by the Federal Reserve Bank of New York as set forth on its public website from time to time, and published on the next succeeding Business Day by the Federal Reserve Bank of New York as an overnight bank funding rate (from and after such date as the Federal Reserve Bank of New York shall commence to publish such composite rate).

(b)The following terms contained in Section 1.02 of the Credit Agreement are hereby amended and restated in their entirety with the following text:

(i)““Alternate Base Rate” means, for any day, a rate per annum equal to the greatest of (a) the Prime Rate in effect on such day, (b) the NYFRB Rate in effect on such day plus ½ of 1% and (c) the Adjusted LIBO Rate for a one month Interest Period on such day (or if such day is not a Business Day, the immediately preceding Business Day) plus 1%, provided that for the purpose of this definition, the Adjusted LIBO Rate for any day shall be based on the LIBO Screen Rate (or if the LIBO Screen Rate is not available for such one month Interest Period, the Interpolated Rate) at approximately the Specified Time on such day. Any change in the Alternate Base Rate due to a change in the Prime Rate, the NYFRB Rate or the Adjusted LIBO Rate shall be effective from and including the effective date of such change in the Prime Rate, the NYFRB Rate or the Adjusted LIBO Rate, respectively. If the Alternate Base Rate is being used as an alternate rate of interest pursuant to Section 2.14 hereof, then the Alternate Base Rate shall be the greater of clause (a) and clause (b) above and shall be determined without reference to clause (c) above. For the avoidance of doubt, if the Alternate Base Rate shall be less than zero, such rate shall be deemed to be zero for purposes of this Agreement.”

(ii)““Federal Funds Effective Rate” means, for any day, the rate calculated by the Federal Reserve Bank of New York based on such day’s federal funds transactions by depositary institutions (as determined in such manner as the Federal Reserve Bank of New York shall set forth on its public website from time to time) and published on the next succeeding Business Day by the Federal Reserve Bank of New York as the federal funds effective rate, provided that if the Federal Funds Effective Rate shall be less than zero, such rate shall be deemed to zero for the purposes of this Agreement.”

2.2    Amendment to Section 3.03. Section 3.03 of the Credit Agreement is hereby amended and restated in its entirety with the following text:

“Section 3.03.        Alternate Rate of Interest. If prior to the first day of any Interest Period:

(a)If prior to the first day of any Interest Period:

(i)the Administrative Agent determines (which determination shall be conclusive and binding absent manifest error) that adequate and reasonable means (including, without limitation, by means of an Interpolated Rate) do not exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period; or

(ii)the Administrative Agent shall have received notice from the Majority Lenders that the Adjusted LIBO Rate or LIBO Rate, as applicable, determined or to be determined for such Interest Period will not adequately and fairly reflect the cost to such Lenders (as conclusively certified by such Lenders) of making or maintaining their affected Loans included in such Borrowing for such Interest Period,

then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by telephone as promptly as practicable thereafter and, until the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective (and such Borrowing shall be automatically converted into ABR Loans on the last day of the applicable Interest Period), and (ii) if any Borrowing Request requests a Eurodollar Borrowing, such Borrowing shall be made either as an ABR Borrowing.

(b)If any Lender determines that any requirement of law has made it unlawful, or if any Governmental Authority has asserted that it is unlawful, for any Lender or its applicable lending office to make, maintain, fund or continue any Eurodollar Borrowing, or any Governmental Authority has imposed material restrictions on the authority of such Lender to purchase or sell, or to take deposits of, dollars in the London interbank market, then, on notice thereof by such Lender to the Borrower through the Administrative Agent, any obligations of such Lender to make, maintain, fund or continue Eurodollar Loans or to convert ABR Borrowings to Eurodollar Borrowings will be suspended until such Lender notifies the Administrative Agent and the Borrower that the circumstances giving rise to such determination no longer exist. Upon receipt of such notice, the Borrower will upon demand from such Lender (with a copy to the Administrative Agent), either convert or prepay all Eurodollar Borrowings of such Lender to ABR Borrowings, either on the last day of the Interest Period therefor, if such Lender may lawfully continue to maintain such Eurodollar Borrowings to such day, or immediately, if such Lender may not lawfully continue to maintain such Loans. Upon any such conversion or prepayment, the Borrower will also pay accrued interest on the amount so converted or prepaid.

(c)If at any time the Administrative Agent determines (which determination shall be conclusive absent manifest error) that (i) the circumstances set forth in Section 3.03(a)(i) have arisen and such circumstances are unlikely to be temporary or (ii) the circumstances set forth in Section 3.03(a)(i) have not arisen but the supervisor for the administrator of the LIBO Screen Rate or a Governmental Authority having jurisdiction over the Administrative Agent has made a public statement identifying a specific date after which the LIBO Screen Rate shall no longer be used for determining interest rates for loans, then the Administrative Agent and the Borrower shall endeavor to establish an alternate rate of interest to the LIBO Rate that gives due consideration to the then prevailing market convention for determining a rate of interest for syndicated loans in the United States at such time, and shall enter into an amendment to this Agreement to reflect such alternate rate

of interest and such other related changes to this Agreement as may be applicable. Notwithstanding anything to the contrary in Section 12.02(b), such amendment shall become effective without any further action or consent of any other party to this Agreement so long as the Administrative Agent shall not have received, within five Business Days of the date notice of such alternate rate of interest is provided to the Lenders, a written notice from the Required Lenders stating that such Required Lenders object to such amendment. Until an alternate rate of interest shall be determined in accordance with this Section 3.03(c) (but, in the case of the circumstances described in Section 3.03(c)(ii), only to the extent the LIBO Screen Rate for such Interest Period is not available or published at such time on a current basis), (x) any Interest Election Request that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective, and (y) if any Borrowing Request requests a Eurodollar Borrowing, such Borrowing shall be made as an ABR Borrowing; provided that, if such alternate rate of interest shall be less than zero, such rate shall be deemed to be zero for the purposes of this Agreement.”

2.3    Amendment to Annex I. The Lenders have agreed to the assignment and reallocation certain Lenders’ respective Commitments and Maximum Credit Amounts (the “Assigned Interests”). On the Amendment Effective Date and after giving effect to such reallocations, the Maximum Credit Amount and Applicable Percentage of each Lender shall be as set forth on Annex I attached hereto and the Borrower and each Lender hereby consents and agrees to the Maximum Credit Amount and Applicable Percentages set forth on such Annex I. With respect to such assignment and reallocation, each Lender acquiring Assigned Interests shall be deemed to have acquired its portion of the Assigned Interests allocated to it from each other Lenders from whom a disposition of Assignment Interests was necessary to achieve the Maximum Credit Amounts and Applicable Percentages set forth on such Annex I pursuant to the terms of an Assignment and Assumption attached as Exhibit G to the Credit Agreement as if each such Lender had executed the necessary Assignment and Assumptions with respect to such reallocation at par (it being understood that any other determinations made with respect to such reallocation shall be made by the Administrative Agent in its reasonable discretion in consultation with any such applicable Lenders and any such Lender and the Borrower shall promptly execute any customary assigned documentation needed or advisable to effectuate such reallocation if reasonably requested by the Administrative Agent). In connection with, and for the purposes of, the assignments and reallocations effected by this Amendment only, the Administrative Agent waives the processing and recordation fee under Section 12.04(b)(ii)(C).

Section 3.    Borrowing Base. Each Lender, the Administrative Agent and the Borrower agree that upon and as of the Amendment Effective Date (as defined below): (a) the November 1, 2017 Scheduled Redetermination shall be deemed to have taken place according to the procedures set forth in the Credit Agreement and (b) the amount of the Borrowing Base shall be increased from $330.0 million to $370.0 million (the “Current Scheduled Redetermination”; such $40.0 million increase to the Borrowing Base, the “Borrowing Base Increase”). After giving effect to the Current Scheduled Redetermination and subject to Section 4 of this Amendment, the Borrowing Base shall remain in effect until otherwise redetermined or adjusted pursuant to the Borrowing Base Adjustment Provisions in accordance with the Credit Agreement. For avoidance of doubt, this provision does not limit the right of the parties to initiate Interim Redeterminations of the Borrowing Base in accordance with Section 2.07(c) of the Credit Agreement or any other Borrowing Base Adjustment Provisions (subject to Section 4 of this Amendment) and the Current Scheduled Redetermination shall not constitute an Interim Redetermination. This Section 3 constitutes the New Borrowing Base Notice delivered in accordance with Section 2.07(d) of the Credit Agreement in connection with the Current Scheduled Redetermination.

Section 4.    Waiver. The Borrower, Administrative Agent and Lenders hereby agrees to (a) the Requested Borrowing Base Waiver and (b) the application of the Requested Alternative Borrowing Base

Adjustment in connection with consummation of the Proposed Debt Incurrence, subject to the following conditions subsequent:

For avoidance of doubt, this provision does not limit the right of the parties to initiate Interim Redeterminations of the Borrowing Base in accordance with Section 2.07(c) or any other Borrowing Base Adjustment Provisions.

In the event that the Borrower fails to incur such Proposed Debt Incurrence within the Incurrence Window, then the Borrower shall pay to the Administrative Agent on behalf of the Lenders, a commitment increase fee in an amount equal to 67.5 basis points multiplied by the Borrowing Base Increase, which fee shall due and payable by the Borrower on the first Business Day after the last day of the Incurrence Window and which fee shall be allocated among the Lenders based on their respective percentage shares of the Borrowing Base Increase.

Section 5.    Conditions Precedent. This Amendment shall become effective on the date (such date, the “Amendment Effective Date”) when each of the following conditions is satisfied (or waived in accordance with Section 12.02(b) of the Credit Agreement):

5.1    The Administrative Agent, the Arranger and the Lenders shall have received all other fees and other amounts due and payable in connection with this Amendment or any other Loan Document on or prior to the Amendment Effective Date, including, to the extent invoiced, reimbursement or payment of all out-of-pocket expenses required to be reimbursed or paid by the Borrower pursuant to this Amendment or any other Loan Document.

5.2    The Administrative Agent shall have received a counterpart of this Amendment signed by the Borrower, the Guarantors and each Lender.

5.3    The Administrative Agent shall have received a certificate of a Responsible Officer of the Borrower certifying as to the representations and warranties in Section 6.2(d) below.

Such declaration shall be final, conclusive and binding upon all parties to the Credit Agreement for all purposes.
