B. The Borrower has requested and the Lenders signatory hereto have agreed to amend certain provisions of the Credit Agreement as set forth herein.

C. Now, therefore, to induce the Administrative Agent and the Lenders to enter into this Amendment and 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 such term in the Credit Agreement as amended by this Amendment. Unless otherwise indicated, all section references in this Amendment refer to sections of the Credit Agreement.

Section 2. Amendments to Credit Agreement.

2.1 Amendments to Section 1.02. Section 1.02 is hereby amended by amending or adding in the appropriate alphabetical order the following terms:

“Agreement” means this Second Amended and Restated Credit Agreement, as amended by the First Amendment dated as of June 9, 2014, the Second Amendment dated as of November 13, 2014, the Third Amendment dated as of June 21, 2016, the Fourth Amendment dated as of December 15, 2016, the Fifth Amendment dated as of November 28, 2017, the Sixth Amendment to Amended and Restated Credit Agreement and Third Amendment to Amended and Restated Guaranty and Collateral Agreement dated as of May 25, 2018, and the Seventh Amendment to Amended and Restated Credit Agreement dated as of August 31, 2018, as the same may be further amended, modified or supplemented from time to time.

“Debt” means, for any Person, the sum of the following (without duplication): (a) all obligations of such Person for borrowed money or evidenced by bonds, bankers’ acceptances, debentures, notes or other similar instruments; (b) all obligations of such Person (whether contingent or otherwise) in respect of letters of credit, surety or other bonds and similar instruments; (c) all accounts payable and all accrued expenses, liabilities or other obligations of such Person to pay the deferred purchase price of Property or services, but excluding those from time to time incurred in the ordinary course of business that are not greater than sixty (60) days past the date such payment is due or that are being contested in good faith by appropriate action and for which adequate reserves have been maintained in accordance with

GAAP; (d) all obligations under Capital Leases; (e) all obligations under Synthetic Leases; (f) all Debt (as defined in the other clauses of this definition) of others secured by (or for which the holder of such Debt has an existing right, contingent or otherwise, to be secured by) a Lien on any Property of such Person, whether or not such Debt is assumed by such Person; (g) all Debt (as defined in the other clauses of this definition) of others guaranteed by such Person or in which such Person otherwise assures a creditor against loss of the Debt (howsoever such assurance shall be made) to the extent of the lesser of the amount of such Debt and the maximum stated amount of such guarantee or assurance against loss; (h) all obligations or undertakings of such Person to maintain or cause to be maintained the financial position or covenants of others or to purchase the Debt or Property of others; (i) obligations to deliver commodities, goods or services, including, without limitation, Hydrocarbons, in consideration of one or more advance payments, other than gas balancing arrangements in the ordinary course of business; (j) obligations to pay for goods or services even if such goods or services are not actually received or utilized by such Person; (k) any Debt of a partnership for which such Person is liable either by agreement, by operation of law or by a Governmental Requirement but only to the extent of such liability; (l) Disqualified Capital Stock; and (m) the undischarged balance of any production payment created by such Person or for the creation of which such Person directly or indirectly received payment. The Debt of any Person shall include all obligations of such Person of the character described above to the extent such Person remains legally liable in respect thereof notwithstanding that any such obligation is not included as a liability of such Person under GAAP. Notwithstanding the foregoing, “Debt” shall not include (1) any obligation arising from agreements of the Parent Guarantor, the Borrower or any Restricted Subsidiary providing for indemnification, contribution, adjustment of purchase price, earn-outs, holdbacks, deferred compensation or similar obligations, in each case, incurred or assumed in connection with the disposition or acquisition of any business, assets or Equity Interests of a Restricted Subsidiary in a transaction permitted by this Agreement or (2) any obligation of a Loan Party in connection with a DrillCo pursuant to the agreement or agreements governing such DrillCo, including obligations to repurchase or otherwise purchase or acquire DrillCo Properties.

“DrillCo” means an entity jointly formed, or an arrangement evidenced by a participation, development, production or similar agreement entered into, in each case, by a Loan Party and one or more other Persons (together with its or their Affiliates, each, a “DrillCo Party”) that (a) provides for a DrillCo Party to fund the majority of the capital for the development of one or more Properties and (b) enables the Loan Parties to achieve one of more of the following objectives: minimization of capital deployment to non-core assets; acceleration of drilling schedule; retention of potentially expiring acreage; or enhancement of long-term value of assets in lieu of outright sale thereof.

“DrillCo Party” has the meaning assigned to such term in the definition of DrillCo.

“DrillCo Properties” means (a) in the case of a DrillCo that is an entity, all Properties contributed, sold or otherwise conveyed to such DrillCo and all Equity Interests in such DrillCo, (b) in the case of a DrillCo that is an agreement, all Properties subject to such agreement, including Properties directly or indirectly conveyed from time to time to a DrillCo Party and therefore no longer owned by a Loan Party, (c) funds and other Property received from a DrillCo Party in connection with a DrillCo, and (d) direct and indirect proceeds of any of the foregoing.

2.8 Amendment to Section 9.16. Section 9.16 is hereby amended by deleting such Section in its entirety and replacing it with the following:

“Section 9.16 Negative Pledge Agreements; Dividend Restrictions The Parent Guarantor and the Borrower will not, and will not permit any of the Restricted Subsidiaries to, create, incur, assume or suffer to exist any contract, agreement or understanding (other than this Agreement, the Security Instruments, the agreements creating Liens permitted by Section 9.03(c), the instruments or agreements evidencing the Senior Unsecured Notes or any Permitted Refinancing Debt in respect thereof, usual and customary restrictions on the pledge or transfer of equity interests in certain joint ventures, usual and customary restrictions in purchase and sale agreements and participation, development, production and similar agreements relating to the Property subject thereof (including DrillCo Properties), restrictions on the granting of Liens contained in agreements subject to Excepted Liens, restrictions on the granting of Liens on the Equity Interests in Unrestricted Subsidiaries, restrictions in agreements of the types contemplated by Section 9.14(b), and restrictions on the granting of Liens in licenses, easements and leases entered into in the ordinary course of business) which in any way prohibits or restricts the granting, conveying, creation or imposition of any Lien on any of its Property in favor of the Administrative Agent and the Lenders or restricts any Restricted Subsidiary from paying dividends or making distributions to the Borrower or any Guarantor, or which requires the consent of or notice to other Persons in connection therewith.”

Similarly, nothing contained in this Amendment shall directly or indirectly in any way whatsoever either: (a) impair, prejudice or otherwise adversely affect the Administrative Agent’s or the Lenders’ right at any time to exercise any right, privilege or remedy in connection with the Loan Documents with respect to any Other Matters, (b) other than the Specified Waivers, amend or alter any provision of the Credit Agreement, the other Loan Documents, or any other contract or instrument, or (c) constitute any course of dealing or other basis for altering any obligation of the Borrower or any right, privilege or remedy of the Administrative Agent or the Lenders under the Credit Agreement, the other Loan Documents, or any other contract or instrument.
