Ladies and Gentlemen: 
 Introductory.
Matador Resources Company, a Texas corporation (the “Company”), proposes to issue and sell to Merrill Lynch, Pierce, Fenner & Smith Incorporated (“Merrill Lynch”) and the other several Initial Purchasers
named in Schedule A hereto (the “Initial Purchasers”), acting severally and not jointly, the respective amounts set forth in such Schedule A of $300,000,000 aggregate principal amount of the Company’s 5.875% Senior Notes due
2026 (the “Notes”). Merrill Lynch has agreed to act as the representative of the several Initial Purchasers (the “Representative”) in connection with the offering and sale of the Notes. 

The Notes will be issued pursuant to that certain indenture, dated as of August 21, 2018 (the “Indenture”), among the
Company, the Guarantors (as defined below) and Wells Fargo Bank, National Association, as trustee (the “Trustee”). The Notes will be issued only in book-entry form in the name of Cede & Co., as nominee of The Depository
Trust Company (the “Depositary”) pursuant to a letter of representations, to be dated on or before the Closing Date (as defined in Section 2 hereof) (the “DTC Agreement”), among the Company, the Trustee and the
Depositary. 
 The Notes constitute “Additional Securities” (as such term is defined in the Indenture) and will be issued pursuant
to and in compliance with the Indenture. The Company has previously issued $750,000,000 aggregate principal amount of 5.875% Senior Notes due 2026 (the “Initial Notes”) under the Indenture. The Notes and the Initial Notes will be
treated as a single series of debt securities for all purposes under the Indenture and the Notes will have terms identical to the Initial Notes, other than the issue date and the issue price. 

 The holders of the Notes will be entitled to the benefits of a registration rights
agreement, to be dated as of October 4, 2018 (the “Registration Rights Agreement”), among the Company, the Guarantors and the Initial Purchasers, pursuant to which the Company and the Guarantors will be required to file with
the Commission (as defined below), under the circumstances set forth therein, (i) a registration statement under the Securities Act (as defined below) relating to another series of debt securities of the Company with terms substantially
identical to the Notes (the “Exchange Notes”) to be offered in exchange for the Notes (the “Exchange Offer”) and (ii) to the extent required by the Registration Rights Agreement, a shelf registration statement
pursuant to Rule 415 of the Securities Act relating to the resale by certain holders of the Notes, and in each case, to use its reasonable best efforts to cause such registration statements to be declared effective. All references herein to the
Exchange Notes and the Exchange Offer are only applicable if the Company and the Guarantors are in fact required to consummate the Exchange Offer pursuant to the terms of the Registration Rights Agreement. 

The payment of principal of, premium, if any, and interest on the Notes will be fully and unconditionally guaranteed on a senior unsecured
basis, jointly and severally by (i) the entities listed on the signature pages hereof as “Guarantors” and (ii) any subsidiary of the Company formed or acquired after the Closing Date that executes an additional guarantee in
accordance with the terms of the Indenture, and their respective successors and assigns (collectively, the “Guarantors”), pursuant to their guarantees (the “Guarantees”). The Notes and the Guarantees attached
thereto are herein collectively referred to as the “Securities”; and the Exchange Notes and the Guarantees attached thereto are herein collectively referred to as the “Exchange Securities.” 

This Agreement, the Registration Rights Agreement, the Securities and the Exchange Securities are referred to herein as the “Specified
Transaction Documents.” The Specified Transaction Documents together with the Indenture are referred to herein as the “Transaction Documents.” 

The Company understands that the Initial Purchasers propose to make an offering of the Securities on the terms and in the manner set forth
herein and in the Pricing Disclosure Package (as defined below) and agrees that the Initial Purchasers may resell, subject to the conditions set forth herein, all or a portion of the Securities to purchasers (the “Subsequent
Purchasers”) on the terms set forth in the Pricing Disclosure Package (the first time when sales of the Securities are made is referred to as the “Time of Sale”). The Securities are to be offered and sold to or through the
Initial Purchasers without being registered with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933 (as amended, the “Securities Act,” which term, as used herein, includes the
rules and regulations of the Commission promulgated thereunder), in reliance upon exemptions therefrom. Pursuant to the terms of the Securities and the Indenture, investors who acquire Securities shall be deemed to have agreed that Securities may
only be resold or otherwise transferred, after the date hereof, if such Securities are registered for sale under the Securities Act or if an exemption from the registration requirements of the Securities Act is available (including the exemptions
afforded by Rule 144A under the Securities Act (“Rule 144A”) or Regulation S under the Securities Act (“Regulation S”)).

 The Company has prepared and delivered to each Initial Purchaser copies of a Preliminary
Offering Memorandum, dated October 1, 2018 (the “Preliminary Offering Memorandum”), and has prepared and delivered to each Initial Purchaser copies of a Pricing Supplement, dated October 1, 2018 (the
“Pricing Supplement”), describing the terms of the Securities, each for use by such Initial Purchaser in connection with its solicitation of offers to purchase the Securities. The Preliminary Offering Memorandum and the
Pricing Supplement are herein referred to as the “Pricing Disclosure Package.” Promptly after this Agreement is executed and delivered, the Company will prepare and deliver to each Initial Purchaser a final offering
memorandum dated the date hereof (the “Final Offering Memorandum”). 
 All references herein to the terms
“Pricing Disclosure Package” and “Final Offering Memorandum” shall be deemed to mean and include all information filed under the Securities Exchange Act of 1934 (as amended, the

Preliminary Offering Memorandum) or the Final Offering Memorandum, as the case may be, and all references herein to the terms “amend,” “amendment” or “supplement” with respect to the Final Offering

manner contemplated by this Agreement and the Offering Memorandum to register the Securities under the Securities Act or, until such time as the Exchange Securities are issued pursuant to an effective registration statement, to qualify the Indenture

indirectly, solicited any offer to buy or offered to sell, or will, directly or

indirectly, solicit any offer to buy or offer to sell, in the United States or to any United States citizen or resident, any security that is or would be integrated with the sale of the
Securities in a manner that would require the Securities to be registered under the Securities Act. None of the Company, its Affiliates, or any person acting on its or any of their behalf (other than the Initial Purchasers, as to whom the Company
makes no representation or warranty) has engaged or will engage, in connection with the offering of the Securities, in any form of general solicitation or general advertising within the meaning of Rule 502 under the Securities Act or in any manner
involving a public offering within the meaning of Section 4(a)(2) of the Securities Act. With respect to those Securities sold in reliance upon Regulation S, (i) none of the Company, its Affiliates or any person acting on its or their
behalf (other than the Initial Purchasers, as to whom the Company makes no representation or warranty) has engaged or will engage in any directed selling efforts within the meaning of Regulation S and (ii) each of the Company and its Affiliates

untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided that this representation and warranty
shall not apply to statements in or omissions from each such Company Additional Written Communication made in reliance upon and in conformity with information furnished to the Company in writing by or on behalf of any Initial Purchaser through the
Representatives expressly for use in any Company Additional Written Communication. 
 (f) Incorporated Documents. The

comply in all material respects with the requirements of the Exchange Act. Each such Incorporated Document, when taken together with the Pricing Disclosure Package, did not as of the Time of Sale, and at the Closing Date will not, contain any untrue

indemnification and contribution and an implied covenant of good faith and fair dealing. The DTC Agreement has been duly authorized by the Company and, on the Closing Date, will have been duly executed and delivered by, and will constitute a valid

the Transaction Documents to which it is a party. The Subsidiaries are the only subsidiaries, direct or indirect, of the Company. The Company and each of the Subsidiaries are duly qualified to transact business and are in good standing in all
jurisdictions in which the conduct of their business requires such qualification; except where the failure to be so qualified or to be in good standing would not reasonably be expected (i) to have a material adverse effect on the condition
(financial or otherwise), properties, assets, operations, earnings, business or prospects of the Company and its Subsidiaries, taken as a whole, whether or not arising from transactions in the ordinary course of business or (ii) to prevent the
consummation of the transactions contemplated hereby (clauses (i) and (ii) are referred to hereinafter as a “Material Adverse Effect”). 

(m) Capitalization. The information set forth under the caption “Capitalization” in the Offering Memorandum is
true and correct (other than for subsequent issuances of capital stock, if any, pursuant to employee benefit plans described in the Offering Memorandum or upon exercise of outstanding options or warrants described in the Pricing Disclosure Package
and the Offering Memorandum, as the case may be). The outstanding shares of common stock of the Company (the “Common Stock”) have been duly authorized and validly issued and are fully paid and
non-assessable. The outstanding shares of capital stock or other equity interests of each of the Subsidiaries have been duly authorized and validly issued, are fully paid (to the extent required under the
applicable limited partnership agreement of such Subsidiary) and non-assessable (except as such non-assessability may be affected by Sections 153.102, 153.112, 153.202 or 153.210 of the Texas Business
Organizations Code with respect to limited partnerships organized under the laws of Texas, Sections 101.114, 101.153 or 101.206 of the Texas Business Organizations Code with respect to limited liability companies organized under the laws of Texas
and Sections 18-607 and 18-804 of the Delaware Limited Liability Company Act with respect to limited liability companies organized under the laws of Delaware) and,
except as disclosed in the Offering Memorandum, are wholly owned by the Company or another Subsidiary free and clear of all liens, pledges, restrictions, encumbrances and equities and claims. 

(n) Preparation of the Financial Statements. The consolidated financial statements of the Company and the Subsidiaries,
together with related notes and schedules as included and incorporated by reference in the Offering Memorandum, present fairly in all material respects the consolidated financial position and the results of operations and cash flows of the Company
and the Subsidiaries, at the indicated dates and for the indicated periods. Such financial statements and related schedules have been prepared in accordance with U.S. generally accepted principles of accounting, consistently applied throughout the
periods involved (“GAAP”), except as disclosed therein, and all adjustments necessary for a fair presentation of results for such periods have been made. The summary financial and statistical data included or incorporated by
reference in the Offering Memorandum presents fairly in all material respects the information shown therein and such data has been compiled on a basis consistent with the financial statements presented therein and the books and records of the
Company. The 

  
 7 

 
interactive data in eXtensible Business Reporting Language (“XBRL”) incorporated by reference in the Offering Memorandum and the Pricing Disclosure Package (i) fairly
present the information contained therein and (ii) have been prepared in accordance with the Commission’s rules and guidelines applicable thereto, in each case of clauses (i) and (ii) in all material respects. 

(o) Statistical Data. The statistical, industry-related and market-related data included in the Offering Memorandum are
based on or derived from sources that the Company reasonably and in good faith believes are reliable and accurate. 
 (p)
Company’s Accounting System. The Company maintains a system of internal accounting controls (“Internal Controls”) in compliance with the Sarbanes-Oxley Act and is sufficient to provide reasonable assurances that
(i) transactions are executed in accordance with management’s general or specific authorization; (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain
accountability for assets; (iii) access to assets is permitted only in accordance with management’s general or specific authorization; (iv) the recorded accountability for assets is compared with existing assets at reasonable intervals and
appropriate action is taken with respect to any differences; and (v) the interactive data in XBRL incorporated by reference in the Offering Memorandum and the Pricing Disclosure Package (i) fairly present the information contained therein

(q) No Significant Deficiencies. Since the date of the most recent balance sheet of the Company and its consolidated
Subsidiaries reviewed or audited by KPMG LLP, and reviewed by the Audit Committee of the Board of Directors of the Company, (i) the Company has not been advised of (A) any significant deficiencies in the design or operation of Internal
Controls that could adversely affect the ability of the Company and each of its Subsidiaries to record, process, summarize and report financial data, or any material weaknesses in Internal Controls and (B) any fraud, whether or not material,
that involves management or other employees who have a significant role in the Internal Controls of the Company and each of its Subsidiaries, and (ii) since that date, there have been no significant changes in Internal Controls or in other
factors that could significantly affect Internal Controls, including any corrective actions with regard to significant deficiencies and material weaknesses. 

(r) Disclosure Controls and Procedures. The Company has established and maintains “disclosure controls and
procedures” (as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act); the Company’s “disclosure controls and procedures” are reasonably
designed to ensure that all information (both financial and non-financial) required to be disclosed by the Company in the reports that it files or furnishes under the Exchange Act is recorded, processed,
summarized and reported within the time periods specified in the rules and regulations of the Commission, and that all such information is accumulated and communicated to the Company’s management as appropriate to allow timely decisions
regarding required disclosure and to make the certifications of the Chief Executive Officer and Chief Financial Officer of the Company required under the Exchange Act with respect to such reports. 

  
 8 

 (s) Independent Accountants. KPMG LLP, which has delivered its
opinion with respect to certain of the audited financial statements and schedules of the Company incorporated by reference in the Offering Memorandum and has reviewed certain unaudited financial statements incorporated by reference in the Offering
Memorandum, is an independent registered public accounting firm with respect to the Company within the meaning of the Securities Act and the applicable rules and regulations of the Public Company Accounting Oversight Board. 

(t) No Material Actions or Proceedings. Except as set forth in the Offering Memorandum, there is no action, suit, claim
or proceeding pending or, to the knowledge of the Company or the Guarantors, threatened against or affecting the Company or any of the Subsidiaries, before any court or administrative agency or which has as the subject thereof any property owned or
leased by the Company or any of the Subsidiaries (i) that are required by the Securities Act to be disclosed on a registration statement on Form S-3 and which is not so disclosed in the Offering
Memorandum or (ii) which, if determined adversely to the Company or any of its Subsidiaries, would reasonably be expected to have a Material Adverse Effect or prevent the consummation of the transactions contemplated hereby. 

(u) Title to Properties. Each of the Company and its Subsidiaries has (i) good and defensible title to all of the
oil and gas properties (including oil and gas wells, producing leasehold interests and appurtenant personal property) owned by the Company and its Subsidiaries, title investigations having been carried out by the Company or its Subsidiaries
consistent with the reasonable practice in the oil and gas industry in the areas in which the Company and its Subsidiaries operate and (ii) good title to all other real and personal property owned by the Company and its Subsidiaries, including
but not limited to such other real and personal property reflected in the financial statements of the Company and its Subsidiaries included and incorporated by reference in the Offering Memorandum, in each case free and clear of all restrictions,
mortgages, pledges, security interests, claims, liens, encumbrances, charges and defects except such as (x) are described in the Offering Memorandum, (y) liens and encumbrances under operating agreements, unitization and pooling
agreements, production sales contracts, farm-out agreements and other oil and gas exploration participation and production agreements, in each case that secure payment of amounts not yet due and payable for
the performance of other unmatured obligations and are of a scope and nature customary in the oil and gas industry or arise in connection with drilling and production operations or (z) such as do not affect the value of the properties of the
Company and its Subsidiaries, considered as one enterprise, and do not interfere in any respect with the use made and proposed to be made of such properties by the Company and its Subsidiaries, considered as one enterprise, with such exceptions as
would not reasonably be expected to have a Material Adverse Effect. All of the leases and subleases under which the Company or any of its Subsidiaries holds or uses properties described in the Offering Memorandum are in full force and effect, with
such exceptions as would not reasonably be expected to have a Material Adverse Effect, and neither the 

  
 9 

 
Company nor any of its Subsidiaries has any notice of any material claim of any sort that has been asserted by anyone adverse to the rights of the Company or its Subsidiaries under any of the
leases or subleases mentioned above, or affecting or questioning the rights of the Company or any Subsidiary thereof to the continued possession or use of the leased or subleased premises, in each case, with such exceptions as would not reasonably
be expected to have a Material Adverse Effect. The working interests in oil, gas and mineral leases or mineral interests which constitute a portion of the real property held by the Company reflect in all material respects the right of the Company to
explore, develop or receive production from such real property, and the care taken by the Company and its Subsidiaries with respect to acquiring or otherwise procuring such leases or mineral interests was generally consistent with standard industry
practices in the areas in which the Company and its Subsidiaries operate for acquiring or procuring leases and interests therein to explore, develop or produce for hydrocarbons. 

(v) Rights-of-Way. The Company and its
Subsidiaries have such consents, easements, rights-of-way or licenses from any person
(“rights-of-way”) as are necessary to enable the Company and its Subsidiaries to conduct its business in the manner described in the Offering
Memorandum, subject to such qualifications as may be set forth in the Offering Memorandum, and except for such rights-of-way the lack of which would not have,
individually or in the aggregate, a Material Adverse Effect. 
 (w) Tax Law Compliance. The Company and the
Subsidiaries have filed all federal, state, local and foreign tax returns which have been required to be filed and have paid all taxes indicated by said returns and all assessments received by them or any of them to the extent that such taxes have
become due and payable by them, except (in any case) (i) for such taxes and assessments that are being contested in good faith and for which an adequate reserve for accrual has been established in accordance with GAAP, (ii) for any such
taxes or assessments that are currently payable without penalty or interest, (iii) where a failure to do so would not reasonably be expected to have a Material Adverse Effect or (iv) to the extent described in the Offering Memorandum.
Neither the Company nor any of the Guarantors has knowledge of any actual or proposed additional material tax assessments. There are no transfer taxes or other similar fees or charges under U.S. federal law or the laws of any U.S. state, or any
political subdivision thereof, required to be paid in connection with the execution and delivery of this Agreement or the issuance or sale by the Company of the Notes. 

(x) No Material Adverse Effect. Since the respective dates as of which information is given in the Offering Memorandum,
exclusive of any amendment or supplement thereto, (i) there has not occurred any Material Adverse Effect, whether or not occurring in the ordinary course of business, and there has not been any material transaction entered into or any material
transaction that is probable of being entered into by the Company or the Subsidiaries, other than transactions in the ordinary course of business and transactions described in the Offering Memorandum, and (ii) none of the Company or any of the
Subsidiaries has incurred any liability or obligation (financial or otherwise), direct or contingent, or entered into any transaction (including any off-balance sheet activity or transaction) that is material
to the Company and the Subsidiaries, as a whole, and there has not been any material change in the capital stock 

  
 10 

 
or partnership interests, as the case may be, or material increase in the short-term debt or long-term debt (including any off-balance sheet activity or
transaction), of any of the Company or the Subsidiaries, or any Material Adverse Effect, or any development involving or which may reasonably be expected to result in a Material Adverse Effect, in each case, except as described in the Offering
Memorandum. The Company and the Subsidiaries have no material liabilities or obligations, or indirect or direct contingent obligations, that are not disclosed in the Company’s financial statements that are incorporated by reference in the
Offering Memorandum. 
 (y) Non-Contravention of Existing Instruments. Neither
the Company nor any of the Subsidiaries is (i) in violation of its Certificate of Formation or other formation document (“Charter”) or bylaws, limited partnership agreement, limited liability company agreement or similar
organizational documents, (ii) in violation of or default (or with the giving of notice or lapse of time or both, will be in default) under any agreement, lease, contract, indenture or other instrument or obligation to which it is a party or by
which it, or any of its properties, is bound or (iii) in violation of any statute, law, rule, regulation, judgment, order or decree of any court, regulatory body, administrative agency, governmental body, arbitrator or other authority having
jurisdiction over the Company or such Subsidiary or any of its properties, as applicable, except, with respect to clauses (i) through (iii), for such violations or defaults as would not, individually or in the aggregate, have a Material Adverse
Effect. The execution and delivery of the Transaction Documents and the consummation of the transactions herein contemplated and the fulfillment of the terms hereof did not and will not, as applicable, conflict with or result in a breach of any of
the terms or provisions of, or constitute a default under (1) the Charter or Bylaws of the Company, (2) any contract, indenture, mortgage, deed of trust or other agreement or instrument to which the Company or any of the Subsidiaries is a
party, or (3) any order, rule or regulation applicable to the Company or any of the Subsidiaries of any court or of any regulatory body or administrative agency or other governmental body having jurisdiction over the Company or any of the
Subsidiaries or any of their respective properties, except, with respect to clauses (2) and (3), where such conflicts, breaches or defaults would not result in a Material Adverse Effect. 

(z) No Further Authorizations or Approvals Required. No permit, consent, approval, authorization, order, registration,
filing or qualification (“Consents”) of or with any court or governmental agency or body having jurisdiction over the Company or any of the Guarantors or any of their respective properties or assets is required in connection with
the offering, issuance or sale by the Company of the Securities, the execution and delivery of the Specified Transaction Documents or the performance of the Transaction Documents by the Company and the Guarantors to the extent a party thereto,
except (i) such Consents as may be required under the Securities Act, the Exchange Act and state securities or “Blue Sky” laws of any jurisdiction, (ii) such Consents as have been obtained or will be obtained prior to the Closing
Date, (iii) such Consents that, if not obtained, could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect or materially impair the ability of the Company and the Guarantors to consummate the
transactions contemplated by this Agreement, and (iv) such Consents as are disclosed in the Pricing Disclosure Package and the Offering Memorandum. 

  
 11 

 (aa) All Necessary Permits, etc. The Company and each of the
Subsidiaries has all licenses, certifications, permits, franchises, approvals, clearances and other regulatory authorizations (“Permits”) from governmental authorities as are necessary to conduct its businesses as currently
conducted and to own, lease and operate its properties in the manner described in the Offering Memorandum except as would not reasonably be expected to have a Material Adverse Effect. There is no claim, proceeding or controversy, pending or, to the
knowledge of the Company or any of the Subsidiaries, threatened, involving the status of or sanctions under any of the Permits and no event has occurred that might allow for the revocation, termination, modification or other impairment of the rights
of the Company or any of the Subsidiaries under such Permit, except, for such claims, proceedings, controversies or events as would not, individually or in the aggregate, have a Material Adverse Effect. 

(bb) No Price Stabilization or Manipulation. Neither the Company nor any of the Guarantors has taken, directly or
indirectly, any action designed to cause or result in, or which has constituted or which might reasonably be expected to constitute, the stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of
the Securities. 
 (cc) Company and Guarantors Not an “Investment Company”. Neither the Company nor any of
the Guarantors is, and after giving effect to the offering and the sale of the Securities and the application of the proceeds thereof as described in the Offering Memorandum will be, an “investment company” within the meaning of such term
under the Investment Company Act of 1940, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Investment Company Act”). 

(dd) Insurance. The Company and each of the Guarantors carry, or are covered by, insurance in such amounts and covering
such risks as is commercially reasonable for the conduct of their respective businesses and the value of their respective properties and as is customary for companies engaged in similar industries. All policies of insurance insuring the Company or
any Guarantor or any of their respective businesses, assets, employees, officers and directors are in full force and effect, and the Company and the Guarantors are in compliance with the terms of such policies in all material respects. There are no
claims by the Company or any Guarantor under any such policy or instrument as to which an insurance company is denying liability or defending under a reservation of rights clause. The Company has no reason to believe that it or any Guarantor will
not be able (i) to renew its existing insurance coverage as and when such policies expire or (ii) to obtain comparable coverage from similar institutions as may be necessary or appropriate to conduct its business as now conducted and at a
cost that would not have a Material Adverse Effect. 
 (ee) Solvency. Each of the Company and the Guarantors is, and
immediately after the Closing Date will be, Solvent. As used herein, the term “Solvent” means, with respect to any person on a particular date, that on such date (i) the fair market value of the assets of such person is greater than
the total amount of liabilities (including contingent liabilities) of such person, (ii) the present fair salable value of the assets of such person is 

  
 12 

 
greater than the amount that will be required to pay the probable liabilities of such person on its debts as they become absolute and matured, (iii) such person is able to realize upon its
assets and pay its debts and other liabilities, including contingent obligations, as they mature and (iv) such person does not have unreasonably small capital. 

(ff) ERISA Compliance. The Company is in compliance in all material respects with all presently applicable provisions of
the Employee Retirement Income Security Act of 1974, as amended, including the regulations and published interpretations thereunder (“ERISA”); no “reportable event” (as defined in ERISA) has occurred with respect to any
“pension plan” (as defined in ERISA) for which the Company would have any liability; the Company has not incurred and does not expect to incur liability under (i) Title IV of ERISA with respect to termination of, or withdrawal from,
any “pension plan” or (ii) Section 412 or 4971 of the Internal Revenue Code of 1986, as amended, including the regulations and published interpretations thereunder (the “Code”); and each “pension plan”
for which the Company would have any liability that is intended to be qualified under Section 401(a) of the Code is so qualified in all material respects and nothing has occurred, whether by action or by failure to act, which would cause the
loss of such qualification. 
 (gg) Compliance with and Liability Under Environmental Laws. Neither the Company nor
any Guarantor is in violation of any statute, rule, regulation, decision or order of any governmental agency or body or any court, domestic or foreign, relating to the use, disposal or release of hazardous chemicals, toxic substances or radioactive
and biological materials or relating to the protection or restoration of the environment or human exposure to hazardous chemicals, toxic substances or radioactive and biological materials (collectively, “Environmental Laws”),
except as would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect. Neither the Company nor the Guarantors own or operate any real property contaminated with any substance that requires remedial action to
be taken under any Environmental Laws, is liable for remedial action at any site where materials regulated under Environmental Laws were disposed by the Company or any Guarantor, or is subject to any claim relating to any Environmental Laws, which
violation, contamination, liability or claim in each case would individually or in the aggregate have a Material Adverse Effect; and the Company is not aware of any pending investigation which might lead to such a claim. There are no costs or
liabilities arising under any Environmental Laws with respect to the operations or properties of the Company and its Subsidiaries (including, without limitation, any capital or operating expenditures required for
clean-up or closure of properties, compliance with Environmental Laws, any permit, license or approval or any related legal constraints on operating activities, and any potential liabilities of third parties
assumed under contract by the Company or its Subsidiaries) that would, individually or in the aggregate, have a Material Adverse Effect. 

(hh) Periodic Review of Costs of Environmental Compliance. In the ordinary course of its business, the Company conducts
a periodic review of the effect of applicable Environmental Laws on the business, operations and properties of the Company and its Subsidiaries, in the course of which it identifies and evaluates material associated costs and liabilities (including,
without limitation, any capital or operating 

  
 13 

 
expenditures required for clean-up, closure of properties or compliance with Environmental Laws or any permit, license or approval, any related constraints
on operating activities and any potential liabilities to third parties). On the basis of such review and the amount of its established reserves and except as disclosed in the Offering Memorandum, the Company has reasonably concluded that such
identified associated costs and liabilities would not, individually or in the aggregate, have a Material Adverse Effect. 

(ii) No Unlawful Contributions or Other Payments. Neither the Company nor any of its Subsidiaries nor, to the knowledge
of the Company, the Guarantors, any director, officer, agent, employee or affiliate of the Company or any of its Subsidiaries is aware of or has taken any action, directly or indirectly, that would result in a violation by such persons of the FCPA,
including, without limitation, making use of the mails or any means or instrumentality of interstate commerce corruptly in furtherance of an offer, payment, promise to pay or authorization of the payment of any money, or other property, gift,
promise to give, or authorization of the giving of anything of value to any “foreign official” (as such term is defined in the FCPA) or any foreign political party or official thereof or any candidate for foreign political office, in
contravention of the FCPA, and the Company, its Subsidiaries and, to the knowledge of the Company and the Guarantors, their affiliates have conducted their businesses in compliance with the FCPA and have instituted and maintain policies and
procedures designed to ensure, and which are reasonably expected to continue to ensure, continued compliance therewith. 

“FCPA” means Foreign Corrupt Practices Act of 1977, as amended, and the rules and regulations thereunder. 

(jj) Intellectual Property Rights. The Company and each of the Guarantors owns, licenses or otherwise has rights in all
United States and foreign patents, trademarks, service marks, tradenames, copyrights, trade secrets and other proprietary rights necessary for the conduct of its respective business as currently carried on and as proposed to be carried on as
described in the Offering Memorandum (collectively and together with any applications or registrations for the foregoing, the “Intellectual Property”), except where the failure to so own or possess would not, individually or
in the aggregate, have a Material Adverse Effect. Neither the Company nor any of its Guarantors has received any notice of infringement of or conflict with any asserted rights of others with respect to any of the foregoing which, individually or in
the aggregate, if the subject of an unfavorable decision, ruling or finding, would have a Material Adverse Effect. 
 (kk)
Compliance with Sarbanes-Oxley. As of the date hereof, the Company is, and on the Closing Date will be, in compliance in all material respects with the applicable provisions of the Sarbanes-Oxley Act of 2002 (the
“Sarbanes-Oxley Act,” which term, as used herein, includes the rules and regulations of the Commission promulgated thereunder) and the rules of the New York Stock Exchange that are then in effect and with which the Company is
required to comply. 

  
 14 

 (ll) Related Party Transactions. No relationship, direct or indirect,
exists between or among the Company or any affiliate of the Company, on the one hand, and any director, officer, member, stockholder, customer or supplier of the Company or any affiliate of the Company, on the other hand, which is required by the
Securities Act to be disclosed in a registration statement on Form S-3 which is not so disclosed in the Offering Memorandum. There are no outstanding loans, advances (except normal advances for business
expenses in the ordinary course of business) or guarantees of indebtedness by the Company to or for the benefit of any of the officers or directors of the Company or any of their respective family members, except as disclosed in the Offering
Memorandum. 
 (mm) Regulations T, U, X. Neither the Company nor any Guarantor nor any agent thereof acting on their
behalf has taken, and none of them will take, any action that might cause this Agreement or the issuance or sale of the Securities to violate Regulation T, Regulation U or Regulation X of the Board of Governors of the Federal Reserve System. 

(nn) Compliance with Labor Laws. No labor problem or dispute with the employees of the Company or the Subsidiaries
exists or, to the Company’s or any of the Guarantor’s knowledge, is threatened or imminent, and the Company and the Guarantors have no knowledge of any existing or imminent labor disturbance by the employees of any of its or its
Subsidiaries’ principal suppliers, contractors, consultants or customers, that would have a Material Adverse Effect. 

(oo) No Conflict with Money Laundering Laws. The operations of the Company and its Subsidiaries, and, to the knowledge
of the Company and its Subsidiaries, are and have been conducted at all times in compliance with all applicable financial recordkeeping and reporting requirements, including those of the Bank Secrecy Act, as amended by Title III of the Uniting and
Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (USA PATRIOT Act), and of the Currency and Foreign Transactions Reporting Act of 1970, as amended, the applicable anti-money laundering
statutes of jurisdictions where such entities conduct business, the rules and regulations thereunder and any related or similar rules, regulations or guidelines issued, administered or enforced by any governmental agency (collectively, the
“Money Laundering Laws”), and no action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving the Company or any of its Subsidiaries or, to the knowledge of the
Company or the Guarantors, with respect to the Money Laundering Laws is pending or, to the knowledge of the Company or the Guarantors, threatened. 

(pp) No Conflict with Sanctions Laws. Neither the Company nor any of its Subsidiaries (collectively, the
“Entity”), nor any director or officer of the Entity nor, to the Entity’s knowledge, any employee agent, affiliate, joint venture or representative of the Entity, is an individual or entity (“Person”) that is,
or is owned or controlled by, a Person that is (i) the subject of any sanctions administered or enforced by the U.S. Department of Treasury’s Office of Foreign Assets Control (“OFAC”), the United Nations Security Council
(“UNSC”), the European Union (“EU”), Her Majesty’s 

  
 15 

 Treasury (“HMT”) or other relevant sanctions authority (collectively,
“Sanctions”), nor (ii) located, organized or resident in a country or territory that is the subject of Sanctions (including, without limitation, Crimea, Burma/Myanmar, Cuba, Iran, North Korea, Sudan and Syria). The Entity represents and
covenants that it will not, directly or indirectly, use the proceeds of the offering, or lend, contribute or otherwise make available such proceeds to any subsidiary, joint venture partner or other Person (A) to fund or facilitate any
activities or business of or with any Person or in any country or territory that, at the time of such funding or facilitation, is the subject of Sanctions; or (B) in any other manner that will result in a violation of Sanctions by any Person
(including any Person participating in the offering, whether as underwriter, advisor, investor or otherwise). The Entity represents and covenants that it has not knowingly engaged in, is not now knowingly engaged in, and will not engage in, any
dealings or transactions with any Person, or in any country or territory, that at the time of the dealing or transaction is or was the subject of Sanctions. 

(qq) Royalties. As of the date hereof, (i) all royalties, rentals, deposits and other amounts owed under the oil
and gas leases constituting the oil and gas properties of the Company and its Subsidiaries have been properly and timely paid, other than amounts held in suspense accounts pending routine payments or related to disputes about the proper
identification of royalty owners and except where the failure to timely pay such amounts would not, individually or in the aggregate, have a Material Adverse Effect; (ii) no material amount of proceeds from the sale or production attributable
to the oil and gas properties of the Company and its Subsidiaries are currently being held in suspense by any purchaser thereof, except where such amounts due would not, individually or in the aggregate, have a Material Adverse Effect, and
(iii) there are no claims under take or pay contracts pursuant to which natural gas purchasers have any make up rights affecting the interests of the Company or its Subsidiaries in their oil and gas properties, except where such claims would
not, individually or in the aggregate, have a Material Adverse Effect. 
 (rr) Preparation of the Reserve Estimates.
The oil and natural gas reserve estimates contained in the Offering Memorandum have been prepared by employees of the Company or the Guarantors and have been audited by an independent reserve engineer, in accordance with Commission guidelines
applied on a consistent basis throughout the periods involved, and the Company and the Guarantors have no reason to believe that such estimates do not fairly reflect the oil and natural gas reserves of the Company and the Guarantors as of the dates
indicated. The information underlying the estimates of the Company’s reserves that was supplied to Netherland, Sewell & Associates, Inc. (the “Reserve Engineer”), for the purposes of auditing the reserve reports
and estimates of the proved reserves of the Company disclosed in the Offering Memorandum, including production and costs of operation, was true and correct in all material respects on the dates such estimates were made, and such information was
supplied and was prepared in accordance with customary industry practices. Other than normal production of the reserves, the impact of the changes in prices and costs, and fluctuations in demand for oil and natural gas and except as disclosed in the
Offering Memorandum, the Company and the Guarantors have no knowledge of any facts or circumstances that would in the aggregate result in a material adverse change in the aggregate net proved reserves, or the aggregate present value or the
standardized measure 

  
 16 

 
of the future net cash flows therefrom, as described in the Offering Memorandum and as reflected in the reports the Reserve Engineer prepared with regard to the proved reserves that the Company
owns. The estimates of such proved reserves and standardized measure as described in the Offering Memorandum and reflected in the reports referenced therein have been prepared in a manner that complies, in all material respects, with the applicable
requirements of the rules and regulations of the Commission with respect to such estimates.

or distribute any such written communication to which the Representative reasonably objects. 
 (b) Amendments and
Supplements to the Final Offering Memorandum and Other Securities Act Matters. If at any time prior to the Closing Date (i) any event shall occur or condition shall exist as a result of which any of the Pricing Disclosure Package as then
amended or supplemented would include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading or
(ii) it is necessary to amend or supplement any of the Pricing Disclosure Package to comply with law, the Company and the Guarantors will promptly notify the Initial Purchasers thereof and forthwith prepare and (subject to Section 3(a)
hereof) furnish to the Initial Purchasers such amendments or supplements to any of the Pricing Disclosure Package as may be necessary so that the statements in any of the Pricing Disclosure 

  
 18 

 
Package as so amended or supplemented will not, in the light of the circumstances under which they were made, be misleading or so that any of the Pricing Disclosure Package will comply with all
applicable law. If, prior to the completion of the placement of the Securities by the Initial Purchasers with the Subsequent Purchasers, any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Final
Offering Memorandum, as then amended or supplemented, in order to make the statements therein, in the light of the circumstances when the Final Offering Memorandum is delivered to a Subsequent Purchaser, not misleading, or if in the judgment of the
Representative or counsel for the Initial Purchasers it is otherwise necessary to amend or supplement the Final Offering Memorandum to comply with law, the Company and the Guarantors agree to promptly prepare (subject to Section 3 hereof), file
with the Commission and furnish at its own expense to the Initial Purchasers, amendments or supplements to the Final Offering Memorandum so that the statements in the Final Offering Memorandum as so amended or supplemented will not, in the light of
the circumstances at the Closing Date and at the time of sale of Securities, be misleading or so that the Final Offering Memorandum, as amended or supplemented, will comply with all applicable law. 

Following the consummation of the Exchange Offer or the effectiveness of an applicable shelf registration statement and for so
long as the Securities are outstanding, if, in the judgment of the Representative, the Initial Purchasers or any of their affiliates (as such term is defined in the Securities Act) are required to deliver a prospectus in connection with sales of, or
market-making activities with respect to, the Securities, the Company and the Guarantors agree to (i) periodically amend the applicable registration statement so that the information contained therein complies with the requirements of
Section 10 of the Securities Act, (ii) amend the applicable registration statement or supplement the related prospectus or the documents incorporated therein when necessary to reflect any material changes in the information provided
therein so that the registration statement and the prospectus will not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances existing
as of the date the prospectus is so delivered, not misleading and (iii) provide the Initial Purchasers with copies of each amendment or supplement filed and such other documents as the Initial Purchasers may reasonably request.

specifically applicable and relate to each offering memorandum, registration statement, prospectus, amendment or supplement referred to in this Section 3. 

(c) Copies of the Offering Memorandum. The Company agrees to furnish the Initial Purchasers, without charge, as many
copies of the Pricing Disclosure Package and the Final Offering Memorandum and any amendments and supplements thereto as they shall reasonably request.

 (d) Blue Sky Compliance. Each of the Company and the Guarantors shall
cooperate with the Representative and counsel for the Initial Purchasers to qualify or register (or to obtain exemptions from qualifying or registering) all or any part of the Securities for offer and sale under the securities laws of the several
states of the United States, the provinces of Canada or any other jurisdictions designated by the Representatives, shall comply with such laws and shall continue such qualifications, registrations and exemptions in effect so long as required for the
distribution of the Securities. Neither the Company nor any of the Guarantors shall be required to qualify as a foreign corporation, limited liability company or limited partnership or to take any action that would subject it to general service of
process in any such jurisdiction where it is not presently qualified or where it would be subject to taxation as a foreign corporation, limited liability company or limited partnership. The Company will advise the Representative promptly of the
suspension of the qualification or registration of (or any such exemption relating to) the Securities for offering, sale or trading in any jurisdiction or any initiation or threat of any proceeding for any such purpose, and in the event of the
issuance of any order suspending such qualification, registration or exemption, each of the Company and the Guarantors shall use its reasonable best efforts to obtain the withdrawal thereof at the earliest possible moment.

described under the caption “Use of Proceeds” in the Pricing Disclosure Package.

not subject to Section 13 or 15 of the Exchange Act, for the benefit of holders and beneficial owners from time to time of the Securities, the Company shall furnish, at its expense, upon request, to holders and beneficial owners of Securities
and prospective purchasers of Securities information satisfying the requirements of Rule 144A(d).

otherwise dispose of or transfer, or announce the offering of, or file any registration statement under the Securities Act in respect of, any debt securities of the Company or securities exchangeable for or convertible into debt securities of the
Company (other than as contemplated by this Agreement and to register the Exchange Securities). 

  
 20 

 (i) No Integration. The Company agrees that it will not and will
cause its Affiliates not to make any offer or sale of securities of the Company of any class if, as a result of the doctrine of “integration” referred to in Rule 502 under the Securities Act, such offer or sale would render invalid (for
the purpose of (i) the sale of the Securities by the Company to the Initial Purchasers, (ii) the resale of the Securities by the Initial Purchasers to Subsequent Purchasers or (iii) the resale of the Securities by such Subsequent
Purchasers to others) the exemption from the registration requirements of the Securities Act provided by Section 4(a)(2) thereof or by Rule 144A or by Regulation S thereunder or otherwise. 

(j) No General Solicitation or Directed Selling Efforts. The Company agrees that it will not and will not permit any of

general advertising within the meaning of Rule 502(c) of Regulation D or in any manner involving a public offering within the meaning of Section 4(a)(2) of the Securities Act or (ii) engage in any directed selling efforts with respect to
the Securities within the meaning of Regulation S, and the Company will and will cause all such persons to comply with the offering restrictions requirement of Regulation S with respect to the Securities. 

(k) No Restricted Resales. During a period of one year after the Closing Date, the Company will not, and will not permit
any of its affiliates (as defined in Rule 144 under the Securities Act) to resell any of the Notes that have been reacquired by any of them. 

(l) Legended Securities. Each certificate for a Note will bear the legend contained in “Transfer Restrictions”
in the Preliminary Offering Memorandum for the time period and upon the other terms stated in the Preliminary Offering Memorandum.

the Pricing Disclosure Package or the Final Offering Memorandum), (vi) the fees and expenses of the Trustee, including the fees and disbursements of counsel for the Trustee in connection with the Indenture, the Securities and the Exchange

counsel) of the Company and the Guarantors in connection with approval of the Securities by the Depositary for “book-entry” transfer, and the performance by the Company and the Guarantors of their respective other obligations under this
Agreement and (x) all expenses incident to the “road show” for the offering of the Securities, if any; provided, however, that the Initial Purchasers will pay for 50% of the cost of any chartered aircraft in connection with the road

recognized statistical rating organization” registered under Section15E of the Exchange Act. 
 (d) Opinion of
Counsel for the Company. On the Closing Date the Initial Purchasers shall have received the favorable opinion of Gibson, Dunn & Crutcher LLP, counsel for the Company, dated as of such Closing Date, the form of which is attached as
Exhibits A-1 and A-2. 
 (e) Opinion of
Counsel for the Initial Purchasers. On the Closing Date the Initial Purchasers shall have received the favorable opinion of Latham & Watkins LLP, counsel for the Initial Purchasers, dated as of such Closing Date, with respect to such
matters as may be reasonably requested by the Initial Purchasers. 
 (f) Officers’ Certificate. On the Closing
Date the Initial Purchasers shall have received a written certificate executed by the Chairman of the Board, Chief Executive Officer or President of the Company and each Guarantor and the Chief Financial Officer or Chief Accounting Officer of the
Company and each Guarantor, dated as of the Closing Date, to the effect set forth in Section 5(c)(ii) hereof, and further to the effect that: 

(i) for the period from and after the date of this Agreement and prior to the Closing Date there has not occurred any Material
Adverse Effect; 
 (ii) the representations, warranties and covenants of the Company and the Guarantors set forth in

(iii) each of the Company and the Guarantors has complied with all the agreements and satisfied all the conditions on its part
to be performed or satisfied at or prior to the Closing Date. 

  
 23 

 (g) Registration Rights Agreement. The Company and the
Guarantors shall have executed and delivered the Registration Rights Agreement, in form and substance reasonably satisfactory to the Initial Purchasers, and the Initial Purchasers shall have received such executed counterparts. 

(h) Depositary. The Securities shall be eligible for clearance and settlement through the facilities of DTC. 

 (i) Additional Documents. On or before the Closing Date, the Initial Purchasers and counsel for the Initial
Purchasers shall have received such information, documents and opinions as they may reasonably require for the purposes of enabling them to pass upon the issuance and sale of the Securities as contemplated herein, or in order to evidence the
accuracy of any of the representations and warranties, or the satisfaction of any of the conditions or agreements, herein contained. 
 If
any condition specified in this Section 5 is not satisfied when and as required to be satisfied, this Agreement may be terminated by the Representative by notice to the Company at any time on or prior to the Closing Date, which termination
shall be without liability on the part of any party to any other party, except that Sections 4, 6, 8 and 9 hereof shall at all times be effective and shall survive such termination. 

SECTION 6. Reimbursement of Initial Purchasers’ Expenses. If this Agreement is terminated by the Representative pursuant to
Section 5 or clauses (i), (iv) or (v) of Section 10 hereof, including if the sale to the Initial Purchasers of the Securities on the Closing Date is not consummated because of any refusal, inability or failure on the part of the
Company to perform any agreement herein or to comply with any provision hereof, the Company agrees to reimburse the Initial Purchasers, severally, upon demand for all
out-of-pocket expenses that shall have been reasonably incurred by the Initial Purchasers in connection with the proposed purchase and the offering and sale of the
Securities, including, without limitation, fees and disbursements of counsel, printing expenses, travel expenses, postage, facsimile and telephone charges. 

SECTION 7. Offer, Sale and Resale Procedures. Each of the Initial Purchasers, on the one hand, and the Company and each of the
Guarantors, on the other hand, hereby agree to observe the following procedures in connection with the offer and sale of the Securities: 

(a) Offers and sales of the Securities will be made only by the Initial Purchasers or Affiliates thereof qualified to do so in
the jurisdictions in which such offers or sales are made. Each such offer or sale shall only be made to persons whom the offeror or seller reasonably believes to be Qualified Institutional Buyers or non-U.S.
persons outside the United States to whom the offeror or seller reasonably believes offers and sales of the Securities may be made in reliance upon Regulation S upon the terms and conditions set forth in Annex I hereto, which Annex I is hereby
expressly made a part hereof. 
 (b) No general solicitation or general advertising (within the meaning of Rule 502 under the
Securities Act) will be used in the United States in connection with the offering of the Securities. 

  
 24 

 (c) Upon original issuance by the Company, and until such time as the same
is no longer required under the applicable requirements of the Securities Act, the Notes (and all securities issued in exchange therefor or in substitution thereof, other than the Exchange Notes) shall bear the following legend: 

“THE SECURITY (OR ITS PREDECESSOR) EVIDENCED HEREBY WAS ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER SECTION 5 OF THE
UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND THE SECURITY EVIDENCED HEREBY MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION
THEREFROM. EACH PURCHASER OF THE SECURITY EVIDENCED HEREBY IS HEREBY NOTIFIED THAT THE SELLER MAY BE RELYING ON THE EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER. THE HOLDER OF THE SECURITY
EVIDENCED HEREBY AGREES FOR THE BENEFIT OF THE COMPANY THAT (A) SUCH SECURITY MAY BE RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (1)(a) INSIDE THE UNITED STATES TO A PERSON WHO THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL
BUYER (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) PURCHASING FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A UNDER THE SECURITIES ACT, (b) OUTSIDE THE
UNITED STATES TO A FOREIGN PERSON IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 903 OR RULE 904 OF REGULATION S UNDER THE SECURITIES ACT, (c) PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT PROVIDED BY RULE 144
THEREUNDER (IF APPLICABLE) OR (d) IN ACCORDANCE WITH ANOTHER EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT (AND BASED UPON AN OPINION OF COUNSEL ACCEPTABLE TO THE COMPANY IF THE COMPANY SO REQUESTS), (2) TO THE COMPANY OR
(3) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT AND, IN EACH CASE, IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES OR ANY OTHER APPLICABLE JURISDICTION AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT
HOLDER IS REQUIRED TO, NOTIFY ANY PURCHASER OF THE SECURITY EVIDENCED HEREBY OF THE RESALE RESTRICTIONS SET FORTH IN CLAUSE (A) ABOVE. NO REPRESENTATION CAN BE MADE AS TO THE AVAILABILITY OF THE EXEMPTION PROVIDED BY RULE 144 FOR RESALE OF THE
SECURITY EVIDENCED HEREBY.” 

  
 25 

 Following the sale of the Securities by the Initial Purchasers to Subsequent Purchasers
pursuant to the terms hereof, the Initial Purchasers shall not be liable or responsible to the Company for any losses, damages or liabilities suffered or incurred by the Company, including any losses, damages or liabilities under the Securities Act,
arising from or relating to any resale or transfer of any Security. 
 SECTION 8. Indemnification. 

(a) Indemnification of the Initial Purchasers. Each of the Company and the Guarantors, jointly and severally, agrees to indemnify and
hold harmless each Initial Purchaser, its affiliates, directors, officers and employees, and each person, if any, who controls any Initial Purchaser within the meaning of the Securities Act and the Exchange Act against any loss, claim, damage,
liability or expense, as incurred, to which such Initial Purchaser, affiliate, director, officer, employee or controlling person may become subject, under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, or
at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the Company), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated
below) arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Offering Memorandum, the Pricing Supplement, any Company Additional Written Communication or the Final Offering
Memorandum (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;
and to reimburse each Initial Purchaser and each such affiliate, director, officer, employee or controlling person for any and all expenses (including the fees and disbursements of counsel chosen by Merrill Lynch) as such expenses are reasonably
incurred by such Initial Purchaser or such affiliate, director, officer, employee or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action;
provided, however, that the foregoing indemnity agreement shall not apply, with respect to an Initial Purchaser, to any loss, claim, damage, liability or expense to the extent, but only to the extent, arising out of or based upon any untrue
statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Initial Purchaser through the Representative expressly for use in
the Preliminary Offering Memorandum, the Pricing Supplement, any Company Additional Written Communication or the Final Offering Memorandum (or any amendment or supplement thereto). The indemnity agreement set forth in this Section 8(a) shall be
in addition to any liabilities that the Company may otherwise have. 
 (b) Indemnification of the Company and the Guarantors. Each
Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless the Company, each Guarantor, each of their respective directors, officers and each person, if any, who controls the Company or any Guarantor within the meaning of
the Securities Act or the Exchange Act, against any loss, claim, damage, liability or expense, as incurred, to which the Company, any Guarantor or any such director, officer or controlling person may become subject, under the Securities Act, the
Exchange Act, or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of such Initial Purchaser), insofar as such loss,
claim, damage, liability or expense (or 

  
 26 

 
actions in respect thereof as contemplated below) arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Offering
Memorandum, the Pricing Supplement, any Company Additional Written Communication or the Final Offering Memorandum (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make
the statements therein, in the light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made
in the Preliminary Offering Memorandum, the Pricing Supplement, any Company Additional Written Communication or the Final Offering Memorandum (or any amendment or supplement thereto), in reliance upon and in conformity with written information
furnished to the Company by or on behalf of such Initial Purchaser through the Representative expressly for use therein; and to reimburse the Company, any Guarantor and each such director, officer or controlling person for any and all expenses
(including the fees and disbursements of counsel) as such expenses are reasonably incurred by the Company, any Guarantor or such director, officer or controlling person in connection with investigating, defending, settling, compromising or paying
any such loss, claim, damage, liability, expense or action. Each of the Company and the Guarantors hereby acknowledges that the only information that the Initial Purchasers through the Representative have furnished to the Company expressly for use
in the Preliminary Offering Memorandum, the Pricing Supplement, any Company Additional Written Communication or the Final Offering Memorandum (or any amendment or supplement thereto) are the statements set forth in the sixth, tenth and eleventh
paragraphs under the caption “Plan of Distribution” in the Preliminary Offering Memorandum and the Final Offering Memorandum. The indemnity agreement set forth in this Section 8(b) shall be in addition to any liabilities that each
Initial Purchaser may otherwise have. 
 (c) Notifications and Other Indemnification Procedures. Promptly after receipt by an
indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 8, notify the indemnifying party
in writing of the commencement thereof; provided that the failure to so notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party under this Section 8 except to the extent that it has been
materially prejudiced by such failure (through the forfeiture of substantive rights and defenses) and shall not relieve the indemnifying party from any liability that the indemnifying party may have to an indemnified party other than under this
Section 8. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in and, to the extent
that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with
counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that a
conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties which are different from
or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such
indemnified party or parties. Upon receipt of notice from the 

  
 27 

 
indemnifying party to such indemnified party of such indemnifying party’s election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying
party will not be liable to such indemnified party under this Section 8 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have
employed separate counsel in accordance with the proviso to the immediately preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (together with local
counsel (in each applicable jurisdiction)), which shall be selected by Merrill Lynch (in the case of counsel representing the Initial Purchasers or their related persons), representing the indemnified parties who are parties to such action) or
(ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action, in each of which cases the fees and
expenses of counsel shall be at the expense of the indemnifying party. 
 (d) Settlements. The indemnifying party under this
Section 8 shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the
indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent
to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such
settlement, compromise or consent (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding and (ii) does not include any statements as to or
any findings of fault, culpability or failure to act by or on behalf of any indemnified party. 
 SECTION 9. Contribution. If the
indemnification provided for in Section 8 hereof is for any reason held to be unavailable to or otherwise insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to therein,
then each indemnifying party shall contribute to the aggregate amount paid or payable by such indemnified party, as incurred, as a result of any losses, claims, damages, liabilities or expenses referred to therein (i) in such proportion as is
appropriate to reflect the relative benefits received by the Company and the Guarantors, on the one hand, and the Initial Purchasers, on the other hand, from the offering of the Securities pursuant to this Agreement or (ii) if the allocation
provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Guarantors,
on the one hand, and the Initial Purchasers, on the other hand, in connection with the statements or omissions or inaccuracies in the representations and warranties herein which resulted in such losses, claims, damages, liabilities or expenses, as
well as any other relevant equitable considerations. The relative benefits received by the Company and the Guarantors, on the one hand, and the Initial Purchasers, on the other hand, in connection with the offering of the Securities pursuant to this
Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company, and the total discount received by the
Initial Purchasers bear to the aggregate initial offering 

  
 28 

 price of the Securities. The relative fault of the Company and the Guarantors, on the one hand, and the
Initial Purchasers, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact or any such inaccurate or
alleged inaccurate representation or warranty relates to information supplied by the Company and the Guarantors, on the one hand, or the Initial Purchasers, on the other hand, and the parties’ relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission or inaccuracy. 
 The amount paid or payable by a party as a result of the
losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Section 8 hereof, any legal or other fees or expenses reasonably incurred by such party in connection with
investigating or defending any action or claim. The provisions set forth in Section 8 hereof with respect to notice of commencement of any action shall apply if a claim for contribution is to be made under this Section 9; provided,
however, that no additional notice shall be required with respect to any action for which notice has been given under Section 8 hereof for purposes of indemnification. 

The Company, the Guarantors and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this
Section 9 were determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this
Section 9. 
 Notwithstanding the provisions of this Section 9, no Initial Purchaser shall be required to contribute any amount in
excess of the discount received by such Initial Purchaser in connection with the Securities distributed by it. No person guilty of fraudulent misrepresentation (within the meaning of Section 11 of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent misrepresentation. The Initial Purchasers’ obligations to contribute pursuant to this Section 9 are several, and not joint, in proportion to their respective commitments as
set forth opposite their names in Schedule A. For purposes of this Section 9, each affiliate, director, officer and employee of an Initial Purchaser and each person, if any, who controls an Initial Purchaser within the meaning of the Securities
Act and the Exchange Act shall have the same rights to contribution as such Initial Purchaser, and each director of the Company or any Guarantor, and each person, if any, who controls the Company or any Guarantor with the meaning of the Securities
Act and the Exchange Act shall have the same rights to contribution as the Company and the Guarantors. 
 SECTION 10. Termination of this
Agreement. Prior to the Closing Date, this Agreement may be terminated by the Representative by notice given to the Company if at any time: (i) trading or quotation in any of the Company’s securities shall have been suspended or
limited by the Commission or by the New York Stock Exchange (the “NYSE”), or trading in securities generally on either the Nasdaq Stock Market or the NYSE shall have been suspended or limited, or minimum or maximum prices shall have
been generally established on any of such quotation system or stock exchange by the Commission or FINRA; (ii) a general banking moratorium shall have been declared by any of federal, New York or Texas authorities; (iii) there shall have
occurred any outbreak or escalation of national or international hostilities or any crisis or calamity, or any change in the United States or international financial markets, or any substantial change or development involving a prospective
substantial change in United States’ 

  
 29 

 
or international political, financial or economic conditions, as in the judgment of the Representative is material and adverse and makes it impracticable or inadvisable to proceed with the
offering sale or delivery of the Securities in the manner and on the terms described in the Pricing Disclosure Package or to enforce contracts for the sale of securities; (iv) in the judgment of the Representative there shall have occurred any
Material Adverse Effect; or (v) the Company shall have sustained a loss by strike, fire, flood, earthquake, accident or other calamity of such character as in the judgment of the Representative may interfere materially with the conduct of the
business and operations of the Company regardless of whether or not such loss shall have been insured. Any termination pursuant to this Section 10 shall be without liability on the part of (i) the Company or any Guarantor to any Initial
Purchaser, except that the Company and the Guarantors shall be obligated to reimburse the expenses of the Initial Purchasers pursuant to Sections 4 and 6 hereof, (ii) any Initial Purchaser to the Company, or (iii) any party hereto to any
other party except that the provisions of Sections 8 and 9 hereof shall at all times be effective and shall survive such termination. 

SECTION 11. Representations and Indemnities to Survive Delivery. The respective indemnities, agreements, representations, warranties
and other statements of the Company, the Guarantors, their respective officers and the several Initial Purchasers set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on
behalf of any Initial Purchaser, the Company, any Guarantor or any of their partners, officers or directors or any controlling person, as the case may be, and will survive delivery of and payment for the Securities sold hereunder and any termination
of this Agreement.

SECTION 13. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto, and to the benefit of the
indemnified parties referred to in Sections 8 and 9 hereof, and in each case their respective successors, and no other person will have any right or obligation hereunder. The term “successors” shall not include any Subsequent Purchaser or
other purchaser of the Securities as such from any of the Initial Purchasers merely by reason of such purchase. 
 SECTION 14. Authority
of the Representative. Any action by the Initial Purchasers hereunder may be taken by Merrill Lynch on behalf of the Initial Purchasers, and any such action taken by Merrill Lynch shall be binding upon the Initial Purchasers. 

SECTION 15. Partial Unenforceability. The invalidity or unenforceability of any section, paragraph or provision of this Agreement shall
not affect the validity or enforceability of any other section, paragraph or provision hereof. If any section, paragraph or provision of this Agreement is for any reason determined to be invalid or unenforceable, there shall be deemed to be made
such minor changes (and only such minor changes) as are necessary to make it valid and enforceable. 
 SECTION 16. Governing Law
Provisions. THIS AGREEMENT AND ANY CLAIM, CONTROVERSY, OR DISPUTE ARISING UNDER OR RELATING TO THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO
BE PERFORMED IN SUCH STATE WITHOUT REGARD TO CONFLICTS OF LAW PRINCIPLES THEREOF. 
 SECTION 17. Default of One or More of the Several
Initial Purchasers. If any one or more of the several Initial Purchasers shall fail or refuse to purchase Securities that it or they have agreed to purchase hereunder on the Closing Date, and the aggregate number of Securities which such
defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to 

  
 31 

 purchase does not exceed 10% of the aggregate number of the Securities to be purchased on such date, the
other Initial Purchasers shall be obligated, severally, in the proportions that the number of Securities set forth opposite their respective names on Schedule A bears to the aggregate number of Securities set forth opposite the names of all such non-defaulting Initial Purchasers, or in such other proportions as may be specified by the Initial Purchasers with the consent of the non-defaulting Initial Purchasers, to
purchase the Securities which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase on the Closing Date. If any one or more of the Initial Purchasers shall fail or refuse to purchase Securities and the
aggregate number of Securities with respect to which such default occurs exceeds 10% of the aggregate number of Securities to be purchased on the Closing Date, and arrangements satisfactory to the Initial Purchasers and the Company for the purchase
of such Securities are not made within 48 hours after such default, this Agreement shall terminate without liability of any party to any other party except that the provisions of Sections 4, 6, 8 and 9 hereof shall at all times be effective and
shall survive such termination. In any such case either the Initial Purchasers or the Company shall have the right to postpone the Closing Date, as the case may be, but in no event for longer than seven days in order that the required changes, if
any, to the Final Offering Memorandum or any other documents or arrangements may be effected. 
 As used in this Agreement, the term
“Initial Purchaser” shall be deemed to include any person substituted for a defaulting Initial Purchaser under this Section 17. Any action taken under this Section 17 shall not relieve any defaulting Initial
Purchaser from liability in respect of any default of such Initial Purchaser under this Agreement. 
 SECTION 18. No Advisory or
Fiduciary Responsibility. Each of the Company and the Guarantors acknowledges and agrees that: (i) the purchase and sale of the Securities pursuant to this Agreement, including the determination of the offering price of the Securities and
any related discounts and commissions, is an arm’s-length commercial transaction between the Company and the Guarantors, on the one hand, and the several Initial Purchasers, on the other hand, and the
Company and the Guarantors are capable of evaluating and understanding and understand and accept the terms, risks and conditions of the transactions contemplated by this Agreement; (ii) in connection with each transaction contemplated hereby
and the process leading to such transaction each Initial Purchaser is and has been acting solely as a principal and is not the agent or fiduciary of the Company and the Guarantors or their respective affiliates, stockholders, creditors or employees
or any other party; (iii) no Initial Purchaser has assumed or will assume an advisory or fiduciary responsibility in favor of the Company and the Guarantors with respect to any of the transactions contemplated hereby or the process leading
thereto (irrespective of whether such Initial Purchaser has advised or is currently advising the Company and the Guarantors on other matters) or any other obligation to the Company and the Guarantors except the obligations expressly set forth in
this Agreement; (iv) the several Initial Purchasers and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company and the Guarantors, and the several Initial
Purchasers have no obligation to disclose any of such interests by virtue of any fiduciary or advisory relationship; and (v) the Initial Purchasers have not provided any legal, accounting, regulatory or tax advice with respect to the offering
contemplated hereby, and the Company and the Guarantors have consulted their own legal, accounting, regulatory and tax advisors to the extent they deemed appropriate. 

  
 32 

 This Agreement supersedes all prior agreements and understandings (whether written or oral)
between the Company, the Guarantors and the several Initial Purchasers, or any of them, with respect to the subject matter hereof. The Company and the Guarantors hereby waive and release, to the fullest extent permitted by law, any claims that the
Company and the Guarantors may have against the several Initial Purchasers with respect to any breach or alleged breach of fiduciary duty. 

SECTION 19. Compliance With USA Patriot Act. In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Initial Purchasers are required to obtain, verify and record information that identifies their respective clients, including the Company, which information may
include the name and address of their respective clients, as well as other information that will allow the Initial Purchasers to properly identify their respective clients. 

SECTION 20. General Provisions. This Agreement constitutes the entire agreement of the parties to this Agreement and supersedes all
prior written or oral and all contemporaneous oral agreements, understandings and negotiations with respect to the subject matter hereof. This Agreement may be executed in two or more counterparts, each one of which shall be an original, with the
same effect as if the signatures thereto and hereto were upon the same instrument. Delivery of an executed counterpart of a signature page to this Agreement by telecopier, facsimile or other electronic transmission (i.e., a “pdf” or
“tif”) shall be effective as delivery of a manually executed counterpart thereof. This Agreement may not be amended or modified unless in writing by all of the parties hereto, and no condition herein (express or implied) may be waived
unless waived in writing by each party whom the condition is meant to benefit. The section headings herein are for the convenience of the parties only and shall not affect the construction or interpretation of this Agreement.

 EXHIBIT A-1 

FORM OF OPINION OF COUNSEL TO THE COMPANY 

Based upon the foregoing, and subject to the assumptions, exceptions, qualifications and limitations set forth herein, we are of the opinion that: 

 

	 	1.	 The Company is a validly existing corporation in good standing under the laws of the State of Texas.

  

	 	2.	 Each Guarantor is a validly existing corporation, limited liability company or limited partnership, as
applicable, in good standing under the laws of the State of Texas. 

  

	 	3.	 The Company and each Guarantor has all requisite corporate, limited liability company or limited partnership
power and authority to (i) own, lease and operate its respective properties and to conduct its respective business as described in the Pricing Disclosure Package and the Offering Memorandum and (ii) execute and deliver the Note Documents
to which it is a party and to perform its obligations thereunder. 

  

	 	4.	 The execution and delivery by the Company and each Guarantor of the Note Documents to which it is a party and
the performance of its obligations thereunder have been duly authorized by all necessary corporate, limited liability company or limited partnership action, as applicable. Each of the Closing Date Note Documents has been duly executed and
delivered by the Company and each Guarantor party thereto. 

  

	 	5.	 Each of the Indenture and the Registration Rights Agreement constitutes a legal, valid and binding obligation
of the Company and each Guarantor party thereto, enforceable against the Company and each such Guarantor in accordance with its terms. 

  

	 	6.	 The Notes, when authenticated in accordance with the provisions of the Indenture and delivered to and paid for
by the Initial Purchasers in accordance with the terms of the Purchase Agreement, will be legal, valid and binding obligations of the Company, entitled to the benefits of the Indenture and enforceable against the Company in accordance with their
terms. The Exchange Notes, when executed and authenticated in accordance with the provisions of the Indenture and delivered in exchange for the Notes in accordance with the provisions of the Registration Rights Agreement, will be legal, valid and
binding obligations of the Company, entitled to the benefits of the Indenture and enforceable against the Company in accordance with their terms. 

  

	 	7.	 When the Notes and the Guarantees endorsed thereon have been duly authenticated in accordance with the
provisions of the Indenture and delivered to and paid for by the Initial Purchasers in accordance with the terms of the Purchase Agreement, the Guarantee of each Guarantor will be a legal, valid and binding obligation of such Guarantor, entitled to
the benefits of the Indenture and enforceable against such Guarantor in accordance with its terms. When the Exchange Notes and the Exchange Note Guarantees endorsed thereon have been duly executed and authenticated in accordance with the provisions
of 

  

  
 Exhibit A-1 
 1 

	 	the Indenture and delivered in exchange for the Notes and the Guarantees in accordance with the provisions of the Registration Rights Agreement, the Exchange Note Guarantee of each Guarantor will be a legal, valid and
binding obligation of such Guarantor, entitled to the benefits of the Indenture and enforceable against such Guarantor in accordance with its terms. 

  

	 	8.	 The execution and delivery by the Company and the Guarantors of the Closing Date Note Documents to which it is
a party, the performance of its obligations thereunder, and the issuance by the Company and the Guarantors of the Notes and the Guarantees to the Initial Purchasers: 

(i) do not and will not violate the charter or bylaws or other constitutive documents of the Company or any of the Guarantors;

 (ii) based solely upon review of such agreements, do not and will not result in a breach of or default under any
agreement (other than employment agreements, stock option plans, stock election plans, stock incentive plans, officer and director indemnification agreements,
change-in-control or severance agreements and deferred compensation plans, as to which we express no opinion) included in the list of exhibits in the Company’s
Annual Report on Form 10-K for the year ended December 31, 2017 and the Quarterly Reports on Form 10-Q filed subsequent to such Annual Report; and 

(iii) do not and will not violate, or require any filing or registration with or consent, approval, authorization or order of
any governmental authority or regulatory body of the States of New York or Texas or the United States of America under, any law, statute, rule or regulation of the States of New York or Texas or the United States of America applicable to the Company
or any of the Guarantors that, in our experience, is generally applicable to transactions in the nature of those contemplated by the Purchase Agreement. 
  

	 	9.	 Assuming the accuracy of the representations and warranties of the Company, the Guarantors and the Initial
Purchasers and compliance by them with their agreements contained in the Purchase Agreement, no registration of the Notes or Guarantees under the Securities Act, and no qualification of the Indenture under the Trust Indenture Act of 1939, as
amended, is required for the sale and delivery of the Notes to the Initial Purchasers on the date hereof or for resales by the Initial Purchasers in the manner contemplated by the Purchase Agreement and the Offering Memorandum, dated October 1,
2018, issued in connection with the offer and sale of the Notes (the “Offering Memorandum”), it being understood that we express no opinion as to any subsequent resale of the Notes or Guarantees. 

 

	 	10.	 Insofar as the statements in the Pricing Disclosure Package and the Offering Memorandum under the captions
“The Offering” and “Description of the Notes” purport to describe specific provisions of the Notes or the other Note Documents, such statements are accurate in all material respects. 

 

  
 Exhibit A-1 
 2 

	 	11.	 Insofar as the statements in the Pricing Disclosure Package and the Offering Memorandum under the caption
“Material United States Federal Income Tax Considerations” purport to summarize matters of United States federal tax law and regulations, such statements are accurate in all material respects, subject to the limitations, qualifications and
assumptions set forth therein. 

  

	 	12.	 Each of the Company and the Guarantors is not and, after giving effect to the sale of the Notes and the use of
proceeds therefrom as described in the Pricing Disclosure Package and the Offering Memorandum, will not be an “investment company” that is required to be registered under the Investment Company Act of 1940, as amended (the “Investment
Company Act”). For purposes of this paragraph 12, the term “investment company” has the meanings ascribed to such term in the Investment Company Act. 

 

  
 Exhibit A-1

 EXHIBIT A-2 

FORM OF 10B-5 LETTER OF COUNSEL TO THE COMPANY 

We have participated in conferences with officers and other representatives of the Company, the Guarantors, representatives of the independent auditors and
independent reserve engineers of the Company and your representatives and counsel at which the contents of the General Disclosure Package and the Final Offering Memorandum and related matters were discussed. Because the purpose of our professional
engagement was not to establish or confirm factual matters and because we did not independently undertake to verify the accuracy, completeness or fairness of the statements set forth in the General Disclosure Package or the Final Offering
Memorandum, we are not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the General Disclosure Package or the Final Offering Memorandum except insofar as such statements
specifically relate to us or as specifically addressed in paragraphs 10 and 11 of our legal opinion addressed to you of even date herewith. Our identification of information as constituting the General Disclosure Package is for the limited purpose
of making the statements set forth in this letter. We express no opinion or belief as to the conveyance of the General Disclosure Package or the Final Offering Memorandum or the information contained therein to investors generally or to any
particular investors at any particular time or in any particular manner. 
 On the basis of the foregoing, and except for (1) the
financial statements and schedules and other information of an accounting or financial nature included or incorporated by reference therein and (2) the audit report of Netherland, Sewell & Associates, Inc. incorporated by reference
therein and any information derived therefrom, as to all of which we express no opinion or belief, no facts have come to our attention that led us to believe that (i) the General Disclosure Package, at the Applicable Time, included an untrue
statement of material fact or omitted to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading or (ii) the Final Offering Memorandum, as of its date or
as of the date hereof, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not
misleading.

Such Initial Purchaser agrees that it has not offered or sold and will not offer or sell the Securities in the United States or to, or for the
benefit or account of, a U.S. person (other than a distributor), in each case, as defined in Rule 902 of Regulation S (i) as part of its distribution at any time and (ii) otherwise until 40 days after the later of the commencement of the
offering of the Securities pursuant hereto and the Closing Date, other than in accordance with Regulation S or another exemption from the registration requirements of the Securities Act.

Such Initial Purchaser agrees that, at or prior to confirmation of a sale of Securities by it to any distributor, dealer or person receiving a
selling concession, fee or other remuneration during the 40-day restricted period referred to in Rule 903 of Regulation S, it will send to such distributor, dealer or person receiving a selling concession, fee
or other remuneration a confirmation or notice to substantially the following effect: 
 “The Securities covered hereby have not been
registered under the U.S. Securities Act of 1933, as amended (the “Securities Act”), and may not be offered and sold within the United States or to, or for the account or benefit of, U.S. persons (i) as part of your distribution at
any time or (ii) otherwise until 40 days after the later of the date the Securities were first offered to persons other than distributors in reliance upon Regulation S and the Closing Date, except in either case in accordance with Regulation S
under the Securities Act (or in accordance with Rule 144A under the Securities Act or to accredited investors in transactions that are exempt from the registration requirements of the Securities Act), and in connection with any subsequent sale by
you of the Securities covered hereby in reliance on Regulation S under the Securities Act during the period referred to above to any distributor, dealer or person receiving a selling concession, fee or other remuneration, you must deliver a notice
to substantially the foregoing effect. Terms used above have the meanings assigned to them in Regulation S under the Securities Act.”

AMENDED AND RESTATED CREDIT AGREEMENT 

This LIMITED CONSENT AND TWELFTH AMENDMENT TO THIRD AMENDED AND RESTATED CREDIT AGREEMENT (this “Amendment”) is entered into

WITNESSETH: 

WHEREAS, the Borrower, the Administrative Agent and the Lenders have entered into that certain Third Amended and Restated Credit

Section 2.10(c) of the Credit Agreement and (ii) both before and immediately after giving effect to the Senior Notes Increase, no Default or Event of Default shall have occurred and be continuing. The consent set forth
in this Section 2 is expressly limited as follows: (A) such consent is limited solely to the Senior Notes Increase on and subject to the terms and conditions hereof and (B) such consent is a limited one-time consent, and nothing contained herein shall obligate the Administrative Agent or the Lenders to grant any additional or future consent, or to grant any waiver of Section 8.13 of

 5.3 Enforceability. This Amendment constitutes the valid and binding obligation of the
Borrower enforceable in accordance with its terms, except as the enforceability thereof may be limited by (i) bankruptcy, insolvency or similar laws affecting creditor’s rights generally, and (ii) equitable principles of general
application. 
 5.4 No Default. After giving effect to this Amendment, no Default or Event of Default has occurred and is

related documents. 
 6.5 Counterparts. This Amendment may be executed in one or more counterparts and by different parties
hereto in separate counterparts each of which when so executed and delivered shall be deemed an original, but all such counterparts together shall constitute but one and the same instrument; signature pages may be detached from multiple separate

only and shall not be deemed to limit, amplify or modify the terms of this Amendment, nor affect the meaning thereof. 
 6.8
Governing Law. This Amendment shall be construed in accordance with and governed by the laws of the State of Texas. 
 6.9
Severability. Any provision of this Amendment held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting
the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction. 

6.10 Reference to and Effect on the Loan Documents.

executed and delivered pursuant to the Credit Agreement to the “Credit Agreement”, shall mean and be a reference to the Credit Agreement as amended by this Amendment.

the Administrative Agent under any of the Loan Documents, nor, except as expressly provided herein, constitute a waiver of any provision of any of the Loan Documents.
