Ladies and Gentlemen: 
 Matador Resources
Company, a Texas corporation (the “Issuer”), proposes to issue and sell to Merrill Lynch, Pierce, Fenner & Smith Incorporated and the other several Initial Purchasers named in Schedule A to the Purchase Agreement (as defined
below) (collectively, the “Initial Purchasers”), upon the terms set forth in a purchase agreement dated December 6, 2016 (the “Purchase Agreement”), $175,000,000 aggregate principal amount of its 6.875% Senior Notes
due 2023 (the “Additional Securities”) to be unconditionally guaranteed (the “Guarantees”) by certain of the Issuer’s subsidiaries who are signatories hereto as guarantors (collectively, the
“Guarantors” and together with the Issuer, the “Company”). The Additional Securities constitute “Additional Securities” (as such term is defined in the Indenture) under the an Indenture, dated as of
April 14, 2015 (the “Indenture”), by and among the Issuer, the Guarantors named therein and Wells Fargo Bank, National Association (the “Trustee”)and will be issued pursuant to and in compliance with the
Indenture. The Issuer has previously issued $400,000,000 aggregate principal amount of 6.875% Senior Notes due 2023 (the “Initial Securities”) under the Indenture.

As an inducement to the Initial Purchasers, the Company agrees with the Initial Purchasers, for the benefit of the holders of the Additional
Securities (including, without limitation, the Initial Purchasers), the Exchange Securities (as defined below) and the Private Exchange Securities (as defined below) (collectively, the “Holders”), as follows: 

1.    Registered Exchange Offer. The Company shall, at its own cost, prepare and file with the Securities and
Exchange Commission (the “Commission”) a registration statement (the “Exchange Offer Registration Statement”) on an appropriate form under the Securities Act of 1933, as amended (the “Securities
Act”), with respect to a proposed offer (the “Registered  

 
Exchange Offer”) to the Holders of Transfer Restricted Securities (as defined in Section 6(d) hereof), who are not prohibited by any law or policy of the Commission from
participating in the Registered Exchange Offer, to issue and deliver to such Holders, in exchange for the Additional Securities, a like aggregate principal amount of debt securities (the “Exchange Securities”) of the Company issued
under the Indenture and identical in all material respects to the Additional Securities (except for the transfer restrictions relating to the Additional Securities and the provisions relating to the matters described in Section 6(d) hereof)
that would be registered under the Securities Act. The Company shall use its reasonable best efforts to cause such Exchange Offer Registration Statement to be declared effective under the Securities Act and shall keep the Registered Exchange Offer
open for not less than 20 business days (or longer, if required by applicable law) after the date notice of the Registered Exchange Offer is mailed to the Holders. 

If the Company commences the Registered Exchange Offer, the Company will be entitled to close the Registered Exchange Offer 30 days after the
commencement thereof; provided, that the Company has accepted all the Additional Securities theretofore validly tendered, and not withdrawn, in accordance with the terms of the Registered Exchange Offer. 

Following the declaration of the effectiveness of the Exchange Offer Registration Statement, the Company shall promptly commence the
Registered Exchange Offer, it being the objective of such Registered Exchange Offer to enable each Holder of Transfer Restricted Securities electing to exchange the Additional Securities for Exchange Securities (assuming that such Holder is not an
affiliate of the Company within the meaning of the Securities Act, acquires the Exchange Securities in the ordinary course of such Holder’s business and has no arrangements or understanding with any person to participate in the distribution of
the Exchange Securities and is not prohibited by any law or policy of the Commission from participating in the Registered Exchange Offer) to trade such Exchange Securities from and after their receipt without any limitations or restrictions under
the Securities Act and without material restrictions under the securities laws of the several states of the United States; provided, however, that the Exchanging Dealers (as defined below) will be required to deliver a prospectus in
connection with resales of Exchange Securities. 
 The Company acknowledges that, pursuant to current interpretations by the
Commission’s staff of Section 5 of the Securities Act, in the absence of an applicable exemption therefrom, (i) each Holder which is a broker-dealer electing to exchange Additional Securities, acquired for its own account as a result of market
making activities or other trading activities, for Exchange Securities (an “Exchanging Dealer”), is required to deliver a prospectus containing the information set forth in (a) Annex A hereto on the cover, (b) Annex B
hereto in the “Exchange Offer Procedures” section and the “Purpose of the Exchange Offer” section, and (c) Annex C hereto in the “Plan of Distribution” section of such prospectus in connection with a sale of any
such Exchange Securities received by such Exchanging Dealer pursuant to the Registered Exchange Offer and (ii) an Initial Purchaser that elects to sell Exchange Securities acquired in exchange for Additional Securities constituting any portion of an
unsold allotment is required to deliver a prospectus containing the information required by Items 507 or 508 of Regulation S-K under the Securities Act, as applicable, in connection with such sale. 

The Company shall use its reasonable best efforts to keep the Exchange Offer Registration Statement effective and to amend and supplement the
prospectus contained therein, 

  
 2 

 
in order to permit such prospectus to be lawfully delivered by all persons subject to the prospectus delivery requirements of the Securities Act for such period of time as such persons must
comply with such requirements in order to resell the Exchange Securities; provided, however, that (i) in the case where such prospectus and any amendment or supplement thereto must be delivered by an Exchanging Dealer or an Initial Purchaser,
such period shall be the lesser of 180 days and the date on which all Exchanging Dealers and the Initial Purchasers have sold all Exchange Securities held by them (unless such period is extended pursuant to Section 3(j) below) and (ii) the
Company shall make such prospectus and any amendment or supplement thereto, available to any broker-dealer for use in connection with any resale of any Exchange Securities for a period of not less than 180 days after the consummation of the
Registered Exchange Offer. 
 If, upon consummation of the Registered Exchange Offer, any Initial Purchaser holds Additional Securities
acquired by it as part of its initial distribution, the Company, simultaneously with the delivery of the Exchange Securities pursuant to the Registered Exchange Offer, shall issue and deliver to such Initial Purchaser upon the written request of
such Initial Purchaser, in exchange (the “Private Exchange”) for the Additional Securities held by such Initial Purchaser, a like principal amount of debt securities of the Company issued under the Indenture and identical in all
material respects (including the existence of restrictions on transfer under the Securities Act and the securities laws of the several states of the United States, but excluding provisions relating to the matters described in Section 6
hereof) to the Additional Securities (the “Private Exchange Securities”). The Additional Securities, the Exchange Securities and the Private Exchange Securities are herein collectively called the “Securities.” 

In connection with the Registered Exchange Offer, the Company shall: 

(a)    deliver to each Holder a copy of the prospectus forming part of the Exchange Offer Registration
Statement, together with an appropriate Letter of Transmittal and related documents; 
 (b)    keep the
Registered Exchange Offer open for not less than 20 business days (or longer, if required by applicable law) after the date notice thereof is mailed to the Holders; 

(c)    utilize the services of a depositary for the Registered Exchange Offer, which may be the Trustee or
an affiliate of the Trustee; 
 (d)    permit Holders to withdraw tendered Additional Securities at any
time prior to the close of business, New York time, on the last business day on which the Registered Exchange Offer shall remain open; and 

(e)    otherwise comply with all applicable laws. 

As soon as practicable after the close of the Registered Exchange Offer or the Private Exchange, as the case may be, the Company shall: 

(x)    accept for exchange all Additional Securities validly tendered and not withdrawn pursuant to the
Registered Exchange Offer and the Private Exchange; and 

  
 3 

 (y)    cause the Trustee to deliver promptly to each Holder
of Exchange Securities or Private Exchange Securities, as the case may be, equal in principal amount to the Additional Securities of such Holder so accepted for exchange. 

The Indenture will provide that the Exchange Securities will not be subject to the transfer restrictions set forth in the Indenture and that
all the Securities will vote and consent together on all matters as one class and that none of the Securities will have the right to vote or consent as a class separate from one another on any matter. 

Interest on each Exchange Security and Private Exchange Security issued pursuant to the Registered Exchange Offer and in the Private Exchange
will accrue from the last interest payment date on which interest was paid on the Additional Securities surrendered in exchange therefor or, if no interest has been paid on the Additional Securities, from October 15, 2016. 

Each Holder participating in the Registered Exchange Offer shall be required to represent to the Company that at the time of the consummation
of the Registered Exchange Offer (i) any Exchange Securities received by such Holder will be acquired in the ordinary course of its business, (ii) such Holder has no arrangements or understanding with any person to participate in the distribution of
the Additional Securities or the Exchange Securities within the meaning of the Securities Act, (iii) such Holder is not an “affiliate,” as defined in Rule 405 of the Securities Act, of the Company or if it is an affiliate, such Holder will
comply with the registration and prospectus delivery requirements of the Securities Act to the extent applicable, (iv) if such Holder is not a broker-dealer, that it is not engaged in, and does not intend to engage in, the distribution of the
Exchange Securities and (v) if such Holder is a broker-dealer, that it will receive Exchange Securities for its own account in exchange for Additional Securities that were acquired as a result of market-making activities or other trading activities
and that it will be required to acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Securities. 

Notwithstanding any other provisions hereof, the Company will ensure that (i) any Exchange Offer Registration Statement and any amendment
thereto and any prospectus forming part thereof and any supplement thereto comply in all material respects with the Securities Act and the rules and regulations thereunder, (ii) any Exchange Offer Registration Statement and any amendment thereto do
not, when they become effective, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading and (iii) any prospectus forming part of any
Exchange Offer Registration Statement, and any supplement to such prospectus, do not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein,
in the light of the circumstances under which they were made, not misleading. 
 2.    Shelf Registration. If,
(i) because of any change in law or in applicable interpretations thereof by the staff of the Commission, the Company is not permitted to effect a Registered Exchange Offer, as contemplated by Section 1 hereof, (ii) the Registered Exchange
Offer is not consummated within 365 days of December 9, 2016 (the “Issue Date”), (iii) any Initial Purchaser so requests with respect to the Additional Securities (or the Private Exchange Securities) not eligible to be exchanged for
Exchange Securities in the Registered Exchange 

  
 4 

 
Offer and held by it following consummation of the Registered Exchange Offer or (iv) any Holder (other than an Exchanging Dealer) is not eligible to participate in the Registered Exchange Offer
or, in the case of any Holder (other than an Exchanging Dealer) that participates in the Registered Exchange Offer, such Holder does not receive freely tradeable Exchange Securities on the date of the exchange, the Company shall take the following
actions: 
 (a)    The Company shall, at its cost, as promptly as practicable (but in no event more than
30 days after so required or requested pursuant to this Section 2) file with the Commission and thereafter shall use its reasonable best efforts to cause to be declared effective (unless it becomes effective automatically upon filing) a registration
statement (the “Shelf Registration Statement” and, together with the Exchange Offer Registration Statement, a “Registration Statement”) on an appropriate form under the Securities Act relating to the offer and sale
of the Transfer Restricted Securities by the Holders thereof from time to time in accordance with the methods of distribution set forth in the Shelf Registration Statement and Rule 415 under the Securities Act (hereinafter, the “Shelf
Registration”) on or prior to the 365th day following the Issue Date in the case of clauses (i) or (ii) above and on or prior to the 180th day after the date on which the Shelf Registration Statement is required to be filed in the case of
clauses (iii) and (iv) above; provided, however, that no Holder (other than an Initial Purchaser) shall be entitled to have the Additional Securities held by it covered by such Shelf Registration Statement unless such Holder agrees in writing
to be bound by all the provisions of this Agreement applicable to such Holder. 
 (b)    The Company
shall use its reasonable best efforts to keep the Shelf Registration Statement continuously effective, in order to permit the prospectus included therein to be lawfully delivered by the Holders of the relevant Additional Securities, for a period of
two years (or for such longer period if extended pursuant to Section 3(j) below) from the date of its effectiveness or such shorter period that will terminate when all the Additional Securities covered by the Shelf Registration Statement (i)
have been sold pursuant thereto or (ii) may be sold without any limitations by non-affiliates of the Company under clause (d)(1)(i) of Rule 144 under the Securities Act, or any successor rule thereof, provided, however, that the six
month period shall be replaced with one year (the “Shelf Registration Period”). The Company shall be deemed not to have used its reasonable best efforts to keep the Shelf Registration Statement effective during the Shelf
Registration Period if it voluntarily takes any action that would result in Holders of Additional Securities covered thereby not being able to offer and sell such Additional Securities during that period, unless such action is required by applicable
law. 
 (c)    Notwithstanding any other provisions of this Agreement to the contrary, the Company shall
cause (i) the Shelf Registration Statement and any amendment thereto and any related prospectus and any supplement thereto, as of the effective date of the Shelf Registration Statement, amendment or supplement, to comply in all material respects
with the Securities Act and the rules and regulations thereunder, (ii) the Shelf Registration Statement and any amendment thereto not to contain any untrue statement of a material fact or omit to state a material fact required to be stated therein
or necessary in order to make the statements therein not misleading and (iii) the prospectus related to the Shelf Registration Statement, and any supplement to such prospectus, not to include an 

  
 5 

 
untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under
which they were made, not misleading. 
 3.    Registration Procedures. In connection with any Shelf Registration
contemplated by Section 2 hereof and, to the extent applicable, any Registered Exchange Offer contemplated by Section 1 hereof, the following provisions shall apply: 

(a)    The Company shall (i) furnish to each Initial Purchaser, prior to the filing thereof with the
Commission, a copy of the Registration Statement and each amendment thereof and each supplement, if any, to the prospectus included therein and, in the event that an Initial Purchaser (with respect to any portion of an unsold allotment from the
original offering) is participating in the Registered Exchange Offer or the Shelf Registration Statement, the Company shall use its reasonable best efforts to reflect in each such document, when so filed with the Commission, such comments as such
Initial Purchaser reasonably may propose; (ii) include the information set forth in Annex A hereto on the cover, in Annex B hereto in the “Exchange Offer Procedures” section and the “Purpose of the Exchange Offer”
section and in Annex C hereto in the “Plan of Distribution” section of the prospectus forming a part of the Exchange Offer Registration Statement and include the information set forth in Annex D hereto in the Letter of
Transmittal delivered pursuant to the Registered Exchange Offer; (iii) if requested by an Initial Purchaser, include the information required by Items 507 or 508 of Regulation S-K under the Securities Act, as applicable, in the prospectus forming a
part of the Exchange Offer Registration Statement; (iv) include within the prospectus contained in the Exchange Offer Registration Statement a section entitled “Plan of Distribution,” reasonably acceptable to the Initial Purchasers, which
shall contain a summary statement of the positions taken or policies made by the staff of the Commission with respect to the potential “underwriter” status of any broker-dealer that is the beneficial owner (as defined in Rule 13d-3 under
the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) of Exchange Securities received by such broker-dealer in the Registered Exchange Offer (a “Participating Broker-Dealer”), whether such positions
or policies have been publicly disseminated by the staff of the Commission or such positions or policies, in the reasonable judgment of the Initial Purchasers based upon advice of counsel (which may be in-house counsel), represent the prevailing
views of the staff of the Commission; and (v) in the case of a Shelf Registration Statement, include in the prospectus included in the Shelf Registration Statement (or, if permitted by Commission Rule 430B(b), in a prospectus supplement that becomes
a part thereof pursuant to Commission Rule 430B(f)) that is delivered to any Holder pursuant to Section 3(d) and (f), the names of the Holders, who propose to sell Additional Securities pursuant to the Shelf Registration Statement, as
selling securityholders. 
 (b)    The Company shall give written notice to the Initial Purchasers, the
Holders of the Additional Securities proposed to be sold under the Shelf Registration Statement and any Participating Broker-Dealer from whom the Company has received prior written notice that it will be a Participating Broker-Dealer in the
Registered Exchange Offer (which notice pursuant to clauses (ii)-(v) hereof shall be accompanied by an instruction to suspend the use of the prospectus until the requisite changes have been made): 

  
 6 

 (i)    when the Registration Statement or any amendment
thereto has been filed with the Commission and when the Registration Statement or any post-effective amendment thereto has become effective; 

(ii)    of any request by the Commission for amendments or supplements to the Registration Statement or the
prospectus included therein or for additional information; 
 (iii)    of the issuance by the Commission
of any stop order suspending the effectiveness of the Registration Statement or the initiation of any proceedings for that purpose, of the issuance by the Commission of a notification of objection to the use of the form on which the Registration
Statement has been filed, and of the happening of any event that causes the Company to become an “ineligible issuer,” as defined in Commission Rule 405; 

(iv)    of the receipt by the Company or its legal counsel of any notification with respect to the
suspension of the qualification of the Additional Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and 

(v)    of the happening of any event that requires the Company to make changes in the Registration
Statement or the prospectus in order that the Registration Statement or the prospectus do not contain an untrue statement of a material fact nor omit to state a material fact required to be stated therein or necessary to make the statements therein
(in the case of the prospectus, in light of the circumstances under which they were made) not misleading. 

(c)    The Company shall make every reasonable effort to obtain the withdrawal at the earliest possible
time, of any order suspending the effectiveness of the Registration Statement. 
 (d)    The Company
shall furnish to each Holder of Additional Securities included within the coverage of the Shelf Registration, without charge, at least one copy of the Shelf Registration Statement and any post-effective amendment or supplement thereto, including
financial statements and schedules, and, if the Holder so requests in writing, all exhibits thereto (including those, if any, incorporated by reference). The Company shall not, without the prior consent of the Initial Purchasers, make any offer
relating to the Additional Securities that would constitute a “free writing prospectus,” as defined in Commission Rule 405. 

(e)    The Company shall deliver to each Initial Purchaser, and to any other Holder who so requests,
without charge, at least one copy of the Exchange Offer Registration Statement and any post-effective amendment thereto, including financial statements and schedules, and, if any Initial Purchaser or any such Holder requests, all exhibits thereto
(including those incorporated by reference). 

  
 7 

 (f)    The Company shall, during the Shelf Registration
Period, deliver to each Holder of Additional Securities included within the coverage of the Shelf Registration, without charge, as many copies of the prospectus (including each preliminary prospectus) included in the Shelf Registration Statement and
any amendment or supplement thereto as such person may reasonably request. The Company consents, subject to the provisions of this Agreement, to the use of the prospectus or any amendment or supplement thereto by each of the selling Holders of the
Additional Securities in connection with the offering and sale of the Additional Securities covered by the prospectus, or any amendment or supplement thereto, included in the Shelf Registration Statement. 

(g)    The Company shall deliver to each Initial Purchaser, any Exchanging Dealer, any Participating
Broker-Dealer and such other persons required to deliver a prospectus following the Registered Exchange Offer, without charge, as many copies of the final prospectus included in the Exchange Offer Registration Statement and any amendment or
supplement thereto as such persons may reasonably request. The Company consents, subject to the provisions of this Agreement, to the use of the prospectus or any amendment or supplement thereto by any Initial Purchaser, if necessary, any
Participating Broker-Dealer and such other persons required to deliver a prospectus following the Registered Exchange Offer in connection with the offering and sale of the Exchange Securities covered by the prospectus, or any amendment or supplement
thereto, included in such Exchange Offer Registration Statement. 
 (h)    Prior to any public offering
of the Additional Securities, pursuant to any Registration Statement, the Company shall register or qualify or cooperate with the Holders of the Additional Securities included therein and their respective counsel in connection with the registration
or qualification of the Additional Securities for offer and sale under the securities or “blue sky” laws of such states of the United States as any Holder of the Additional Securities reasonably requests in writing and do any and all other
acts or things reasonably necessary or advisable to enable the offer and sale in such jurisdictions of the Additional Securities covered by such Registration Statement; provided, however, that the Company shall not be required to (i)
qualify generally to do business in any jurisdiction where it is not then so qualified or (ii) take any action which would subject it to general service of process or to taxation in any jurisdiction where it is not then so subject. 

(i)    To the extent the Additional Securities are not in book-entry form, the Company shall cooperate with
the Holders of the Additional Securities to facilitate the timely preparation and delivery of certificates representing the Additional Securities to be sold pursuant to any Registration Statement free of any restrictive legends and in such
denominations and registered in such names as the Holders may request a reasonable period of time prior to sales of the Additional Securities pursuant to such Registration Statement. 

(j)    Upon the occurrence of any event contemplated by clauses (ii) through (v) of Section 3(b)
above during the period for which the Company is required to maintain an effective Registration Statement, the Company shall promptly prepare and file a post-effective amendment to the Registration Statement or a supplement to the related

  
 8 

 
prospectus and any other required document so that, as thereafter delivered to Holders of the Additional Securities or purchasers of Additional Securities, the prospectus will not contain an
untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. If the Company notifies the
Initial Purchasers, the Holders of the Additional Securities and any known Participating Broker-Dealer in accordance with clauses (ii) through (v) of Section 3(b) above to suspend the use of the prospectus until the requisite changes to the
prospectus have been made, then the Initial Purchasers, the Holders of the Additional Securities and any such Participating Broker-Dealers shall suspend use of such prospectus, and the period of effectiveness of the Shelf Registration Statement
provided for in Section 2(b) above and the Exchange Offer Registration Statement provided for in Section 1 above shall each be extended by the number of days from and including the date of the giving of such notice to and
including the date when the Initial Purchasers, the Holders of the Additional Securities and any known Participating Broker-Dealer shall have received such amended or supplemented prospectus pursuant to this Section 3(j). During the period
during which the Company is required to maintain an effective Shelf Registration Statement pursuant to this Agreement, the Company will prior to the three-year expiration of that Shelf Registration Statement file, and use its reasonable best efforts
to cause to be declared effective (unless it becomes effective automatically upon filing) within a period that avoids any interruption in the ability of Holders of Additional Securities covered by the expiring Shelf Registration Statement to make
registered dispositions, a new registration statement relating to the Additional Securities, which shall be deemed the “Shelf Registration Statement” for purposes of this Agreement. 

(k)    Not later than the effective date of the applicable Registration Statement, the Company will provide
a CUSIP number for the Additional Securities, the Exchange Securities or the Private Exchange Securities, as the case may be, and provide the Trustee with certificates for the Additional Securities, the Exchange Securities or the Private Exchange
Securities, as the case may be, in a form eligible for deposit with The Depository Trust Company. 

(l)    The Company will comply with all rules and regulations of the Commission to the extent and so long
as they are applicable to the Registered Exchange Offer or the Shelf Registration and will make generally available to its security holders (or otherwise provide in accordance with Section 11(a) of the Securities Act) an earnings statement
satisfying the provisions of Section 11(a) of the Securities Act, no later than 45 days after the end of a 12-month period (or 90 days, if such period is a fiscal year) beginning with the first month of the Company’s first fiscal quarter
commencing after the effective date of the Registration Statement, which statement shall cover such 12-month period. 

(m)    The Company has caused the Indenture to be qualified under the Trust Indenture Act of 1939, as
amended. In the event that such qualification would require the appointment of a new trustee under the Indenture, the Company shall appoint a new trustee thereunder pursuant to the applicable provisions of the Indenture. 

  
 9 

 (n)    The Company may require each Holder of Additional
Securities to be sold pursuant to the Shelf Registration Statement to furnish to the Company such information regarding the Holder and the distribution of the Additional Securities as the Company may from time to time reasonably require for
inclusion in the Shelf Registration Statement, and the Company may exclude from such registration the Additional Securities of any Holder that unreasonably fails to furnish such information within a reasonable time after receiving such request. 

(o)    The Company shall enter into such customary agreements (including, if requested, an underwriting
agreement in customary form) and take all such other action, if any, as any Holder of the Additional Securities shall reasonably request in order to facilitate the disposition of the Additional Securities pursuant to any Shelf Registration. 

(p)    In the case of any Shelf Registration, the Company shall (i) make reasonably available for
inspection by the Holders of the Additional Securities, any underwriter participating in any disposition pursuant to the Shelf Registration Statement and any attorney, accountant or other agent retained by the Holders of the Additional Securities or
any such underwriter all relevant financial and other records, pertinent corporate documents and properties of the Company and (ii) cause the Company’s officers, directors, employees, accountants and auditors to supply all relevant information
reasonably requested by the Holders of the Additional Securities or any such underwriter, attorney, accountant or agent in connection with the Shelf Registration Statement, in each case, as shall be reasonably necessary to enable such persons, to
conduct a reasonable investigation within the meaning of Section 11 of the Securities Act; provided, however, that the foregoing inspection and information gathering shall be coordinated on behalf of the Initial Purchasers by you and
on behalf of the other parties, by one counsel designated by and on behalf of such other parties as described in Section 4 hereof; provided, further, however, that any information that is designated in writing by the
Company, in good faith, as confidential at the time of delivery of such information shall be kept confidential by the Holders or any such underwriter, attorney, accountant or other agent, unless such disclosure is made in connection with a court
proceeding or required by law, or such information is or becomes available to the public generally or through a third party without, to the knowledge of any recipient of confidential information, an accompanying obligation of confidentiality or is
independently developed. 
 (q)    In the case of any Shelf Registration, the Company, if requested by
any Holder of the Additional Securities covered thereby, shall cause (i) its counsel to deliver an opinion and updates thereof relating to the Additional Securities in customary form addressed to such Holders and the managing underwriters, if any,
thereof and dated, in the case of the initial opinion, the effective date of such Shelf Registration Statement (it being agreed that the matters to be covered by such opinion shall include, without limitation, the good standing of the Company and
its subsidiaries; the due authorization, execution and delivery of the relevant agreement of the type referred to in Section 3(o) hereof; the due authorization, execution, authentication and issuance, and the validity and enforceability, of
the applicable Additional Securities; the absence of governmental approvals required to be obtained in connection with the Shelf Registration Statement, the offering and sale of the applicable Additional Securities, or any agreement of the type

  
 10 

 
referred to in Section 3(o) hereof; the compliance as to form of such Shelf Registration Statement and any documents incorporated by reference therein and of the Indenture with the
requirements of the Securities Act and the Trust Indenture Act, respectively; and (A) as of the date of the opinion and as of the effective date of the Shelf Registration Statement or most recent post-effective amendment thereto, as the case may be,
the absence from such Shelf Registration Statement and the prospectus included therein, as then amended or supplemented, and from any documents incorporated by reference therein and (B) as of an applicable time identified by such Holders or managing
underwriters, the absence from such prospectus taken together with any other documents identified by such Holders or managing underwriters, in the case of (A) and (B), of an untrue statement of a material fact or the omission to state therein a
material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of any such incorporated documents, in the light of the circumstances existing at the time that such documents were filed with the
Commission under the Exchange Act)); (ii) its officers to execute and deliver all customary documents and certificates and updates thereof requested by any underwriters of the applicable Additional Securities and (iii) its independent public
accountants and the independent public accountants with respect to any other entity for which financial information is provided in the Shelf Registration Statement to provide to the selling Holders of the applicable Additional Securities and any
underwriter therefor a comfort letter in customary form and covering matters of the type customarily covered in comfort letters in connection with primary underwritten offerings, subject to receipt of appropriate documentation as contemplated, and
only if permitted, by Statement of Auditing Standards No. 72. 
 (r)    In the case of the Registered
Exchange Offer, if requested by any Initial Purchaser or any known Participating Broker-Dealer, the Company shall cause (i) its counsel to deliver to such Initial Purchaser or such Participating Broker-Dealer signed opinions in the form set forth in
Section 5(b) of the Purchase Agreement with such changes as are customary in connection with the preparation of a Registration Statement and (ii) its independent public accountants and the independent public accountants with respect to any other
entity for which financial information is provided in the Registration Statement to deliver to such Initial Purchaser or such Participating Broker-Dealer a comfort letter, in customary form, meeting the requirements as to the substance thereof as
set forth in Sections 5(a) and 5(b) of the Purchase Agreement, with appropriate date changes. 

(s)    If a Registered Exchange Offer or a Private Exchange is to be consummated, upon delivery of the
Additional Securities by Holders to the Company (or to such other person as directed by the Company) in exchange for the Exchange Securities or the Private Exchange Securities, as the case may be, the Company shall mark, or cause to be marked, on
the Additional Securities so exchanged that such Additional Securities are being canceled in exchange for the Exchange Securities or the Private Exchange Securities, as the case may be; in no event shall the Additional Securities be marked as paid
or otherwise satisfied. 
 (t)    The Company will use its reasonable best efforts to (a) if the
Additional Securities have been rated prior to the initial sale of such Additional Securities, confirm 

  
 11 

 
such ratings will apply to the Additional Securities covered by a Shelf Registration Statement, or (b) if the Additional Securities were not previously rated, cause the Additional Securities
covered by a Shelf Registration Statement to be rated with the appropriate rating agencies, but in each case only if so requested by Holders of a majority in aggregate principal amount of Additional Securities covered by such Registration Statement,
or by the managing underwriters, if any. 
 (u)    In the event that any broker-dealer registered under
the Exchange Act shall underwrite any Additional Securities or participate as a member of an underwriting syndicate or selling group or “assist in the distribution” (within the meaning of the Conduct Rules (the “Rules”) of
the Financial Industry Regulatory Authority (“FINRA”)) thereof, whether as a Holder of such Additional Securities or as an underwriter, a placement or sales agent or a broker or dealer in respect thereof, or otherwise, the Company
will assist such broker-dealer in complying with the requirements of such Rules, including, without limitation, by (i) if such Rules, including Rule 2720, shall so require, engaging a “qualified independent underwriter” (as defined in Rule
2720) to participate in the preparation of the Registration Statement relating to such Additional Securities, to exercise usual standards of due diligence in respect thereto and, if any portion of the offering contemplated by such Registration
Statement is an underwritten offering or is made through a placement or sales agent, to recommend the yield of such Additional Securities, (ii) indemnifying any such qualified independent underwriter to the extent of the indemnification of
underwriters provided in Section 5 hereof and (iii) providing such information to such broker-dealer as may be required in order for such broker-dealer to comply with the requirements of the Rules. 

(v)    The Company shall use its reasonable best efforts to take all other steps necessary to effect the
registration of the Additional Securities covered by a Registration Statement contemplated hereby. 

4.    Registration Expenses. The Company shall bear all fees and expenses incurred in connection with the
performance of its obligations under Sections 1 through 3 hereof (including the reasonable fees and expenses, if any, of counsel for the Initial Purchasers incurred in connection with the Registered Exchange Offer), whether or not the
Registered Exchange Offer or a Shelf Registration is filed or becomes effective, and, in the event of a Shelf Registration, shall bear or reimburse the Holders of the Additional Securities covered thereby for the reasonable fees and disbursements of
one firm of counsel designated by the Holders of a majority in principal amount of the Additional Securities covered thereby to act as counsel for the Holders of the Additional Securities in connection therewith. Each Holder shall be responsible for
paying all underwriting discounts and commissions, if any, relating to the sale or disposition of such Holder’s Securities pursuant to a Shelf Registration Statement. 

5.    Indemnification. 

(a)    The Company and each of the Guarantors, jointly and severally, agree to indemnify and hold harmless
each Holder of the Additional Securities, any Participating Broker-Dealer and each person, if any, who controls such Holder or such Participating Broker-Dealer within the meaning of the Securities Act or the Exchange Act (each

  
 12 

 
Holder, any Participating Broker-Dealer and such controlling persons are referred to collectively as the “Indemnified Parties”) from and against any losses, claims, damages or
liabilities, joint or several, or any actions in respect thereof (including, but not limited to, any losses, claims, damages, liabilities or actions relating to purchases and sales of the Additional Securities) to which each Indemnified Party may
become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in a
Registration Statement or prospectus or in any amendment or supplement thereto or in any preliminary prospectus or “issuer free writing prospectus,” as defined in Commission Rule 433 (“Issuer FWP”), relating to a Shelf
Registration, or arise out of, or are based upon, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and shall reimburse, as incurred, the
Indemnified Parties for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action in respect thereof; provided, however, that the Company and each
Guarantor will not be liable in any such case to the extent that such loss, claim, damage or liability arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in a Registration Statement
or prospectus or in any amendment or supplement thereto or in any preliminary prospectus or Issuer FWP relating to a Shelf Registration in reliance upon and in conformity with written information pertaining to such Holder and furnished to the
Company by or on behalf of such Holder specifically for inclusion therein. 
 (b)    Each Holder of the
Additional Securities, severally and not jointly, will indemnify and hold harmless the Company and each Guarantor, their directors and officers and each person, if any, who controls the Company or such Guarantor within the meaning of the Securities
Act or the Exchange Act from and against any losses, claims, damages or liabilities or any actions in respect thereof, to which the Company or any such Guarantor, their directors and officers or any such controlling person may become subject under
the Securities Act, the Exchange Act or otherwise, insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in a Registration
Statement or prospectus or in any amendment or supplement thereto or in any preliminary prospectus or Issuer FWP relating to a Shelf Registration, or arise out of or are based upon the omission or the alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein not misleading, but in each case only to the extent that the untrue statement or omission or alleged untrue statement or omission was made in reliance upon and in
conformity with written information pertaining to such Holder and furnished to the Company by or on behalf of such Holder specifically for inclusion therein; and, subject to the limitation set forth immediately preceding this clause, shall
reimburse, as incurred, the Company or any such Guarantor, their directors and officers or any such controlling person for any legal or other expenses reasonably incurred by the Company or any such Guarantor, their directors and officers or any such
controlling person in connection with investigating or defending any loss, claim, damage, liability or action in respect thereof. This indemnity agreement will be in addition to any liability that such Holder may otherwise have to the Company, any
Guarantor, their directors and officers or any such controlling person. 

  
 13 

 (c)    Promptly after receipt by an indemnified party under
this Section 5 of notice of the commencement of any action or proceeding (including a governmental investigation), such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section
5, notify the indemnifying party of the commencement thereof; but the failure to notify the indemnifying party shall not relieve the indemnifying party from any liability that it may have under subsection (a) or (b) above except to the extent
that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further that the failure to notify the indemnifying party shall not relieve it from any liability that it may
have to an indemnified party otherwise than under subsection (a) or (b) above. In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be
entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except
with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof the indemnifying party will not be liable to
such indemnified party under this Section 5 for any legal or other expenses, other than reasonable costs of investigation, subsequently incurred by such indemnified party in connection with the defense thereof. No indemnifying party shall,
without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such
indemnified party unless such settlement (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action, and (ii) does not include a statement as to or an admission of
fault, culpability or a failure to act by or on behalf of any indemnified party. 
 (d)    If the
indemnification provided for in this Section 5 is unavailable or insufficient to hold harmless an indemnified party under subsections (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the
indemnifying party or parties on the one hand and the indemnified party on the other from the exchange of the Additional Securities, pursuant to the Registered Exchange Offer, or (ii) if the allocation provided by the foregoing clause (i) 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 indemnifying party or parties on the one hand and the indemnified party on
the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities (or actions in respect thereof) as well as any other relevant equitable considerations. The relative fault of the parties shall be
determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company and the Guarantors on the
one hand or such Holder or such other indemnified party, as the case may be, on the other, and the parties’ relative intent, knowledge, access to information and opportunity to correct or 

  
 14 

 
prevent such statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d)
shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding any other provision
of this Section 5(d), the Holders of the Additional Securities shall not be required to contribute any amount in excess of the amount by which the net proceeds received by such Holders from the sale of the Additional Securities pursuant to a
Registration Statement exceeds the amount of damages which such Holders have otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this subsection (d), each person, if any, who controls such
indemnified party within the meaning of the Securities Act or the Exchange Act shall have the same rights to contribution as such indemnified party and each person, if any, who controls the Company or any Guarantor within the meaning of the
Securities Act or the Exchange Act shall have the same rights to contribution as the Company and the Guarantors. 

(e)    The agreements contained in this Section 5 shall survive the sale of the Additional
Securities pursuant to a Registration Statement and shall remain in full force and effect, regardless of any termination or cancellation of this Agreement or any investigation made by or on behalf of any indemnified party. 

6.    Additional Interest Under Certain Circumstances. 

(a)    Additional interest (the “Additional Interest”) with respect to the Additional
Securities shall be assessed as follows if any of the following events occur (each such event in clauses (i) through (iii) below a “Registration Default”): 

(i)    If obligated to file a Shelf Registration Statement pursuant to (A) Sections 2(i)-(ii) above,
the Shelf Registration Statement has not been declared effective by the Commission (or become effective automatically) on or prior to the 365th day after the Issue Date, or (B) Sections 2(iii-iv) above, the Shelf Registration Statement has
not been declared effective by the Commission (or become effective automatically) on or prior to the 180th day after the date on which the Shelf Registration Statement is required to be filed; 

(ii)    If the Registered Exchange Offer has not been consummated on or before the 365th day after the
Issue Date; or 
 (iii)    If after either the Exchange Offer Registration Statement or the Shelf
Registration Statement is declared (or becomes automatically) effective (A) such Registration Statement thereafter ceases to be effective during the periods specified in Sections 1 and 2, as applicable; or (B) such Registration
Statement or the related prospectus ceases to be usable (except as permitted in subsection (b)) in connection with resales of Transfer Restricted Securities during the periods 

  
 15 

 
specified herein because either (1) any event occurs as a result of which the related prospectus forming part of such Registration Statement would include any untrue statement of a material fact
or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made not misleading, (2) it shall be necessary to amend such Registration Statement or supplement the related
prospectus, to comply with the Securities Act or the Exchange Act or the respective rules thereunder, or (3) such Registration Statement is a Shelf Registration Statement that has expired before a replacement Shelf Registration Statement has become
effective. 
 Additional Interest shall accrue on the Additional Securities over and above the interest set forth in the title of the
Additional Securities from and including the date on which any such Registration Default shall occur to but excluding the date on which all such Registration Defaults have been cured. In the event such Registration Defaults are not previously cured,
all Registration Defaults shall be cured on the date that each Additional Security is no longer a Transfer Restricted Security. The rate of the Additional Interest will be 0.25% per year for the first 90-day period immediately following the
occurrence of a Registration Default, and such rate will increase by an additional 0.25% per year with respect to each subsequent 90-day period until all Registration Defaults have been cured, up to a maximum Additional Interest rate of 1.00% per
year. The Issuer will pay such Additional Interest on regular interest payment dates. Such Additional Interest will be in addition to any other interest payable from time to time with respect to the Additional Securities and the Exchange Securities.
The Company will not be required to pay Additional Interest for more than one Registration Default at any given time. Following the cure of all Registration Defaults, the accrual of Additional Interest will cease and the interest rate will revert to
the original rate, 6.875%. The Additional Interest due pursuant to this Section 6(a) shall be the sole remedy for any Registration Default. 

(b)    A Registration Default referred to in Section 6(a)(iii)(B) hereof shall be deemed not to have
occurred and be continuing in relation to a Shelf Registration Statement or the related prospectus if (i) such Registration Default has occurred solely as a result of (x) the filing of a post-effective amendment to such Shelf Registration Statement
to incorporate annual audited financial information with respect to the Company where such post-effective amendment is not yet effective and needs to be declared effective to permit Holders to use the related prospectus or (y) other material events,
with respect to the Company that would need to be described in such Shelf Registration Statement or the related prospectus and (ii) in the case of clause (y), the Company is proceeding promptly and in good faith to amend or supplement such Shelf
Registration Statement and related prospectus to describe such events; provided, however, that in any case if such Registration Default occurs for a continuous period in excess of 60 days, Additional Interest shall be payable in accordance
with the above paragraph from the day such Registration Default would have been deemed to occur but for this Section 6(b) until such Registration Default is cured. 

(c)    Any amounts of Additional Interest due pursuant to Section 6(a) above will be payable in cash
on the regular interest payment dates with respect to the Additional Securities. The amount of Additional Interest will be determined by 

  
 16 

 
multiplying the applicable Additional Interest rate by the principal amount of the Additional Securities, multiplied by a fraction, the numerator of which is the number of days such Additional
Interest rate was applicable during such period (determined on the basis of a 360-day year comprised of twelve 30-day months), and the denominator of which is 360. 

(d)    “Transfer Restricted Securities” means each Additional Security until (i) the date
on which such Transfer Restricted Security has been exchanged by a person other than a broker-dealer for a freely transferable Exchange Security in the Registered Exchange Offer, (ii) following the exchange by a broker-dealer in the Registered
Exchange Offer of an Additional Security for an Exchange Security, the date on which such Exchange Security is sold to a purchaser who receives from such broker-dealer on or prior to the date of such sale a copy of the prospectus contained in the
Exchange Offer Registration Statement, (iii) the date on which such Additional Security has been effectively registered under the Securities Act and disposed of in accordance with the Shelf Registration Statement or (iv) the date on which such
Additional Securities are distributed to the public pursuant to Rule 144 under the Securities Act or are saleable by non-affiliates of the Company pursuant to Rule 144(d)(l)(i) under the Securities Act, provided, however, that the six month
period shall be replaced with one year. 
 7.    Rules 144 and 144A. The Company shall use its reasonable best
efforts to file the reports required to be filed by it under the Securities Act and the Exchange Act in a timely manner and, if at any time the Company is not required to file such reports, it will, upon the request of any Holder of Additional
Securities, make publicly available other information so long as necessary to permit sales of their securities pursuant to Rules 144 and 144A. The Company covenants that it will take such further action as any Holder of Additional Securities may
reasonably request, all to the extent required from time to time to enable such Holder to sell Additional Securities without registration under the Securities Act within the limitation of the exemptions provided by Rules 144 and 144A (including the
requirements of Rule 144A(d)(4)). The Company will provide a copy of this Agreement to prospective purchasers of Additional Securities identified to the Company by the Initial Purchasers upon request. Upon the request of any Holder of Additional
Securities, the Company shall deliver to such Holder a written statement as to whether it has complied with such requirements. Notwithstanding the foregoing, nothing in this Section 7 shall be deemed to require the Company to register any of
its securities pursuant to the Exchange Act. 
 8.    Underwritten Registrations. If any of the Transfer
Restricted Securities covered by any Shelf Registration are to be sold in an underwritten offering, the investment banker or investment bankers and manager or managers that will administer the offering will be selected by the Holders of a majority
in aggregate principal amount of such Transfer Restricted Securities to be included in such offering. 
 No person may participate in any
underwritten registration hereunder unless such person (i) agrees to sell such person’s Transfer Restricted Securities on the basis reasonably provided in any underwriting arrangements approved by the persons entitled hereunder to approve such
arrangements and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements.

supplemented, and waivers or consents to departures from the provisions hereof may not be given, except by the Company and the written consent of the Holders of a majority in principal amount of (or, in the case of any Additional Interest, all) the
Additional Securities affected by such amendment, modification, supplement, waiver or consent.

 ANNEX A 

Each broker-dealer that receives Exchange Securities for its own account pursuant to the Registered Exchange Offer must acknowledge that it
will deliver a prospectus in connection with any resale of such Exchange Securities. The Letter of Transmittal states that by so acknowledging and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an
“underwriter” within the meaning of the Securities Act. This Prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of Exchange Securities received in exchange for
Additional Securities where such Additional Securities were acquired by such broker-dealer as a result of market-making activities or other trading activities. The Company has agreed that, for a period of 180 days after the consummation of the
Registered Exchange Offer, it will make this Prospectus available to any broker-dealer for use in connection with any such resale. See “Plan of Distribution.”

 ANNEX B 

Each broker-dealer that receives Exchange Securities for its own account in exchange for Securities, where such Additional Securities were

 ANNEX C 

PLAN OF DISTRIBUTION 

Each broker-dealer that receives Exchange Securities for its own account pursuant to the Registered Exchange Offer must acknowledge that it
will deliver a prospectus in connection with any resale of such Exchange Securities. This Prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of Exchange Securities received
in exchange for Additional Securities where such Additional Securities were acquired as a result of market-making activities or other trading activities. The Company has agreed that, for a period of 180 days after the effective date of the Exchange
Offer Registration Statement, it will make this prospectus, as amended or supplemented, available to any broker-dealer for use in connection with any such resale. In addition,
until                 , 20                 (90 days after the consummation of the
Registered Exchange Offer), all dealers effecting transactions in the Exchange Securities may be required to deliver a prospectus. 
 The
Company will not receive any proceeds from any sale of Exchange Securities by broker-dealers. Exchange Securities received by broker-dealers for their own account pursuant to the Exchange Offer may be sold from time to time in one or more
transactions in the over-the-counter market, in negotiated transactions, through the writing of options on the Exchange Securities or a combination of such methods of resale, at market prices prevailing at the time of resale, at prices related to
such prevailing market prices or negotiated prices. Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions from any such broker dealer or the
purchasers of any such Exchange Securities. Any broker-dealer that resells Exchange Securities that were received by it for its own account pursuant to the Exchange Offer and any broker or dealer that participates in a distribution of such Exchange
Securities may be deemed to be an “underwriter” within the meaning of the Securities Act and any profit on any such resale of Exchange Securities and any commission or concessions received by any such persons may be deemed to be
underwriting compensation under the Securities Act. The Letter of Transmittal states that, by acknowledging that it will deliver and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within
the meaning of the Securities Act. 
 For a period of 180 days after the consummation of the Registered Exchange Offer, the Company will
promptly send additional copies of this Prospectus and any amendment or supplement to this Prospectus to any broker-dealer that requests such documents as provided in the Letter of Transmittal. The Company has agreed to pay all expenses incident to
the Exchange Offer (including the expenses of one counsel for the Holders of the Additional Securities) other than commissions or concessions of any brokers or dealers and will indemnify the Holders of the Additional Securities (including any
broker-dealers) against certain liabilities, including liabilities under the Securities Act.

 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 (the “Initial Purchasers”), acting severally and not jointly, the respective amounts
set forth in such Schedule A of $175,000,000 aggregate principal amount of the Company’s 6.875% Senior Notes due 2023 (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 April 14, 2015 (the “Indenture”), among the Company, the Guarantors (as defined below) and Wells Fargo Bank, National Association, as trustee (the “Trustee”), pursuant to which
the Issuers previously issued, on April 14, 2015, $400,000,000 in aggregate principal amount of their 6.875% Senior Notes due 2023. 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 holders of the Notes will be entitled to the benefits of a registration rights agreement, to be dated as of
December 9, 2016 (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, the Exchange Securities, and 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

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 December 5, 2016 (the
“Preliminary Offering Memorandum”), and has prepared and delivered to each Initial Purchaser copies of a Pricing Supplement, dated December 6, 2016 (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 “Exchange Act,” which term, as used herein, includes the rules and regulations of the Commission promulgated thereunder) prior to the Time
of Sale and incorporated by reference in the Pricing Disclosure Package (including 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 Memorandum shall be deemed to mean and include all information filed under the Exchange Act after the Time of Sale and incorporated by reference in the
Final Offering Memorandum. 
 The Company hereby confirms its agreements with the Initial Purchasers as follows: 

SECTION 1. Representations and Warranties. Each of the Company and the Guarantors, jointly and severally, hereby represents, warrants

(a) No Registration Required. Subject to compliance by the Initial Purchasers with the representations and warranties
set forth in Section 2 hereof and with the procedures set forth in Section 7 hereof, it is not necessary in connection with the offer, sale and delivery of the Securities to the Initial Purchasers and to each Subsequent Purchaser in the
manner contemplated by this Agreement and the Offering Memorandum to register the Securities under the Securities Act. The Indenture has been qualified under the Trust Indenture Act of 1939 (the “Trust Indenture Act,” which term, as

 (b) No Integration of
Offerings or General Solicitation. None of the Company, its affiliates (as such term is defined in Rule 501 under the Securities Act) (each, an “Affiliate”), 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, directly or 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. 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 and any person acting on its or their behalf (other than the Initial Purchasers, as to whom the Company makes no representation or warranty) has complied and will comply with the offering restrictions set forth in Regulation S.

system. 
 (d) The Pricing Disclosure Package and Final Offering Memorandum. Neither the Pricing Disclosure Package,
as of the Time of Sale, nor the Final Offering Memorandum, as of its date or (as amended or supplemented in accordance with Section 3(a), as applicable) as of the Closing Date, contains an untrue statement of a material fact or omits to state a

the Representative expressly for use in the Pricing Disclosure Package, the Final Offering Memorandum or amendment or supplement thereto, as the case may be. The Pricing Disclosure Package contains, and the Final Offering Memorandum will contain,
all the information specified in, and meeting the requirements of, Rule 144A. The Company has not distributed and will not distribute, prior to the later of the Closing Date and the completion of the Initial Purchasers’ distribution of the
Securities, any offering material in connection with the offering and sale of the Securities other than the Pricing Disclosure Package and the Final Offering Memorandum. 

(e) Company Additional Written Communications. The Company has not prepared, made, used, authorized, approved or
distributed and will not prepare, make, use, authorize, approve or distribute any written communication that constitutes an offer to sell or solicitation of an offer to buy the Securities other than (i) the Pricing Disclosure Package,
(ii) the Final Offering Memorandum and (iii) any electronic road show or other written communications, in each case used in accordance with Section 3(a). Each such communication by the Company or its agents and representatives
pursuant to clause (iii) of the preceding sentence (each, a “Company Additional Written Communication”), 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 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.

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 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. 
 (g) The
Purchase Agreement. This Agreement has been duly authorized, executed and delivered by the Company and the Guarantors. 

(h) The Registration Rights Agreement and DTC Agreement. The Registration Rights Agreement has been duly authorized and,
on the Closing Date, will have been duly executed and delivered by, and will constitute a valid and binding agreement of, the Company and the Guarantors, enforceable in accordance with its terms, except as the enforcement thereof may be limited by

enforceability is considered in a proceeding in equity or at law) (the “Enforceability Exceptions”) and (ii) public policy, applicable law relating to fiduciary duties and indemnification and contribution and an implied
covenant of good faith and fair dealing. The DTC Agreement has been duly authorized and, on the Closing Date, will have been duly executed and delivered by, and will constitute a valid and binding agreement of, the Company and the Guarantors,
enforceable in accordance with its terms, except as the enforcement thereof may be limited by the Enforceability Exceptions.

the respective forms contemplated by the Indenture and have been duly authorized for issuance pursuant to this Agreement and the Indenture; the Guarantees of the Notes, at the Closing Date, will have been duly executed by each of the Guarantors and,
when the Notes have been authenticated in the manner provided for in the Indenture and issued and 

  
 5 

 
delivered against payment of the purchase price therefor, the Guarantees of the Notes will constitute valid and binding agreements of the Guarantors; and, when the Exchange Notes have been

case, enforceable in accordance with their terms, except as the enforcement thereof may be limited by the Enforceability Exceptions and will be entitled to the benefits of the Indenture. 

(j) Authorization of the Indenture. The Indenture has been duly authorized, executed and delivered by the Company and
the Guarantors and (assuming the due authorization, execution and delivery thereof by the Trustee) constitutes a valid and binding agreement of the Company and the Guarantors, enforceable against the Company and the Guarantors in accordance with its

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 

  
 6 

 
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”)

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

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

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. 
 (s) Independent Accountants. Each of
(i) Grant Thornton, LLP, which has certified certain financial statements of the Company and delivered its opinion with respect to the audited financial statements and schedules included and incorporated by reference in the Offering Memorandum,

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, threatened against or affecting the Company or any of the Subsidiaries, before any court or administrative agency or which has 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 in Form S-3 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. 

  
 8 

 (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 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. 

  
 9 

 (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. The Company has no 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 by the Company 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, 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 Guarantors, other than transactions in the ordinary course of business and changes and transactions described in
the Offering Memorandum, and (ii) none of the Company or any of the Guarantors has incurred any liability or obligation (financial or otherwise), direct or contingent, or entered into any transaction (including any off-balance sheet activities
or transactions), not in the ordinary course of business, that is material to the Company and the Guarantors, as a whole, and there has not been any material change in the capital stock 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 activities or transactions), of any of the Company or the Guarantors, 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 Guarantors have no material liabilities or obligations, or indirect or direct contingent obligations, that are not disclosed in
the Company’s financial statements 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 

  
 10 

 
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 will not 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 or the execution, delivery and 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. 

(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. 

  
 11 

 (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 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

Company nor any Guarantor is in violation of any statute, any 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

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 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, its 

  
 13 

 
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

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, and 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. 

(ll) Related Party Transactions. No relationship, direct or indirect, exists between or among any of 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 knowledge, is threatened or imminent, and the Company has 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. 

  
 14 

 (oo) No Conflict with Money Laundering Laws. The operations of the Company
and its Subsidiaries are and have been conducted at all times in compliance with applicable financial recordkeeping and reporting requirements of the Currency and Foreign Transactions Reporting Act of 1970, as amended, the applicable anti-money
laundering statutes of jurisdictions where the Company and its Subsidiaries 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 with respect to
the Money Laundering Laws is pending or, to the knowledge of the Company, threatened. 
 (pp) No Conflict with Sanctions
Laws. None of 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 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 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, 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 could not, individually or in the aggregate, have a Material Adverse Effect on the Company or any of its Subsidiaries; (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 could not, individually or in the aggregate, have
a Material Adverse Effect on the Company or any of the Subsidiaries, and (iii) there are no claims under take 

  
 15 

 
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 could not, individually or in the aggregate, have a Material Adverse Effect on the Company or any of its Subsidiaries. 

(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 has 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 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. 

(ss) Independent Petroleum Engineers. The Reserve Engineer is an independent petroleum engineer with respect to the
Company and the Guarantors.

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 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. 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

 (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

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

  
 24 

 
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.” 

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. 

  
 25 

 (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 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 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
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 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 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 fifth, ninth and tenth 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 

  
 26 

 
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 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 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

  
 27 

 
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 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. 

  
 28 

 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’ 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.

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 

  
 30 

 
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 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 

  
 31 

 
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. 

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 validly existing and in good standing under the laws of the State of Texas, and each of the Guarantors is validly
existing and in good standing under the laws of the State of Texas. 
 2. Each of the Company and the Guarantors has the requisite
corporate, limited liability company or limited partnership, as applicable, power and authority (i) to own, lease and operate its respective properties and to conduct its respective business as described in the Pricing Disclosure Package and
the Final Offering Memorandum and (ii) to enter into and perform its respective obligations under the Transaction Documents to which it is a party, in each case in all material respects. 

3. This Agreement has been duly authorized, executed and delivered by the Company and each of the Guarantors. 

4. The Indenture has been duly authorized, executed and delivered by the Company and each of the Guarantors and (assuming the due
authorization, execution and delivery thereof by the Trustee) is a valid and legally binding agreement of the Company and each of the Guarantors, enforceable against the Company and each of the Guarantors in accordance with its terms, provided that
the enforceability thereof is subject to (i) applicable bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws relating to or affecting the rights and remedies of creditors’ generally or by general
principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law) and (ii) public policy, applicable law relating to fiduciary duties and indemnification and contribution and an implied covenant
of good faith and fair dealing (the “Enforceability Exceptions”). 
 5. The Notes have been duly authorized, executed and
delivered by the Company and, assuming the due authorization and execution and delivery of the Indenture by the Trustee and the due authentication of the Notes by the Trustee and upon payment and delivery in accordance with this Agreement, will
constitute valid and legally binding obligations of the Company, enforceable against the Company in accordance with their terms, except as such enforceability may be limited by the Enforceability Exceptions, and will be entitled to the benefits of
the Indenture. 
 6. The Guarantees have been duly authorized, executed and delivered by the Guarantors and, assuming the due authorization
and execution and delivery of the Indenture by the Trustee and the due authentication of the Notes by the Trustee and upon payment and delivery in accordance with this Agreement, will constitute valid and legally binding obligations of the
Guarantors, enforceable against the Guarantors in accordance with their terms, except as such enforceability may be limited by the Enforceability Exceptions and will be entitled to the benefits of the Indenture. 

  
 Exhibit A-1 

1 

 7. The Exchange Notes have been duly authorized by the Company and, when duly executed,
authenticated, issued and delivered as contemplated by the Registration Rights Agreement and the Indenture, and assuming the due authorization, execution and delivery of (A) the Indenture by the Trustee and (B) the Registration Rights
Agreement by the Initial Purchasers, will be duly and validly issued and outstanding and will constitute valid and legally binding obligations of the Company, enforceable against the Company in accordance with their terms, except as such
enforceability may be limited by the Enforceability Exceptions, and will be entitled to the benefits of the Indenture. 
 8. The Exchange
Guarantees have been duly authorized by each of the Guarantors and, when each global certificate representing the Exchange Notes has been duly executed, authenticated, issued and delivered as provided in the Registration Rights Agreement and the
Indenture, and assuming the due authorization, execution and delivery of (A) the Indenture by the Trustee and (B) the Registration Rights Agreement by the Initial Purchasers, the Exchange Guarantees will be valid and legally binding
obligations of each of the Guarantors, enforceable against each of the Guarantors in accordance with their terms, except as such enforceability may be limited by the Enforceability Exceptions. 

9. The Registration Rights Agreement has been duly authorized, executed and delivered by the Company and each of the Guarantors and, assuming
the due authorization, execution and delivery thereof by the other parties thereto, constitutes a valid and legally binding obligation of each of the Company and the Guarantors, enforceable against each of the Company and the Guarantors in
accordance with its terms, except as such enforceability may be limited by the Enforceability Exceptions and except that the indemnity and contribution provisions thereunder may be limited by applicable laws, general principles of equity and public
policy. 
 10. The statements set forth in each of the Pricing Disclosure Package and the Final Offering Memorandum under the captions
“The Offering” and “Description of the Notes,” insofar as they purport to constitute summaries of the terms of the Securities, the Indenture, the Exchange Securities and the Registration Rights Agreement, are accurate in all
material respects. 
 11. The statements under the caption “Material United States Federal Income Considerations” in the Pricing
Disclosure Package and the Final Offering Memorandum, insofar as they purport to constitute a summary of matters of United States federal tax law and regulations or legal conclusions with respect thereto, are accurate in all material respects,
subject to the limitations, qualifications and assumptions set forth therein. 
 12. None of the issuance and sale of the Securities, the
execution, delivery and performance of the Transaction Documents by the Company and the Guarantors to the extent a party thereto, or the consummation of the transactions contemplated thereby (i) constitutes or will constitute a violation of the
provisions of the Certificate of Formation or Bylaws of the Company or the certificate of formation, bylaws, limited liability company agreement or 

  
 Exhibit A-1 

2 

 
partnership agreement, as applicable, of the Guarantors, (ii) constitutes or will constitute a breach or violation of, or a default (or an event which, with notice or lapse of time or both,
would constitute such a default) under any agreement filed or incorporated by reference as an exhibit to the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015 (the
“Form 10-K”), or (iii) results in a violation by the Company or any of the Guarantors of any law, statute, rule or regulation of the United States of America, the State of Texas or the
State of New York applicable to the Company and the Guarantors (other than securities laws or anti-fraud laws), which breaches, violations or defaults, in the case of clauses (ii) or (iii), would, individually or in the aggregate, have a
Material Adverse Effect. 
 13. No filing, consent, approval, authorization, order, registration or qualification under the federal laws of
the United States of America, the laws of the State of Texas or the laws of the State of New York is required for the execution, delivery and performance of the Transaction Documents by the Company and the Guarantors to the extent a party thereto or
for the offering, issuance, sale or delivery of the Securities by the Company and the Guarantors pursuant to this Agreement, except for (i) such consents, approvals, authorizations, orders and registrations or qualifications as may be required
under applicable state securities laws or blue sky laws in connection with the purchase and resale of the Securities by the Initial Purchasers, (ii) with respect to the Exchange Securities, such consents, approvals, authorizations, orders and
registrations or qualifications as may be required under the Securities Act, the Trust Indenture Act and applicable state securities or blue sky laws as contemplated by the Registration Rights Agreement, (iv) any consent, approval,
authorization, order, registration or qualification or other action that is or has been obtained or made prior to the Closing Date or (v) such consents, approvals, authorizations, orders and registrations or qualifications as disclosed in the
Pricing Disclosure Package and the Final Offering Memorandum. In rendering the opinion expressed in this paragraph 13, such counsel need not express any opinion as to the matters addressed in paragraph 15 below. 

14. The Company is not and, after giving effect to the offering and sale of the Securities and the application of the proceeds thereof as
described in the Pricing Disclosure Package and the Final Offering Memorandum, will not be, or be required to register as, an “investment company” within the meaning of the Investment Company Act of 1940, as amended. 

15. Assuming (i) the accuracy of the representations and warranties and compliance with the agreements of the Company and Guarantors
contained in this Agreement and (ii) the accuracy of the representations and warranties and compliance with the agreements of the Initial Purchasers contained in this Agreement, no registration of the Securities under the Securities Act is
required with respect to the purchase of the Securities by you or the initial resale of the Securities by you to qualified institutional buyers or non-U.S. persons in the manner contemplated by the Purchase Agreement, the Pricing Disclosure Package
and the Offering Memorandum. Such counsel need express no opinion, however, as to when or under what circumstances any Securities initially sold by you may be offered or resold. 

  
 Exhibit A-1 

3 

 In rendering such opinion, such counsel may rely as to matters involving the application of laws
of any jurisdiction other than the laws of the State of Texas or the federal law of the United States of America, to the extent they deem proper and specified in such opinion, upon the opinion (which shall be dated the Closing Date shall be
satisfactory in form and substance to the Initial Purchasers, shall expressly state that the Initial Purchasers may rely on such opinion as if it were addressed to them and shall be furnished to the Initial Purchasers) of other counsel of good
standing whom they believe to be reliable and who are satisfactory to counsel for the Initial Purchasers; provided, however, that such counsel shall further state that they believe that they and the Initial Purchasers are justified in relying upon
such opinion of other counsel, and as to matters of fact, to the extent they deem proper, on certificates of responsible officers of the Company and public officials.

 EXHIBIT A-2 

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

We have reviewed the Pricing Disclosure Package and the Final Offering Memorandum and have participated in conferences with officers and other representatives
of the Company, with representatives of the Company’s independent registered public accounting firm and independent petroleum engineer, and with your representatives and your counsel, at which the contents of the Pricing Disclosure Package, the
Final Offering Memorandum and related matters were discussed. The purpose of our professional engagement was not to establish or confirm factual matters set forth in the Pricing Disclosure Package or the Final Offering Memorandum, and we have not
undertaken to verify independently any of the factual matters in such documents. Moreover, many of the determinations required to be made in the preparation of the Pricing Disclosure Package and the Final Offering Memorandum involve matters of a
non-legal nature. Accordingly, we are not passing upon, and do not assume any responsibility for, the accuracy, completeness or fairness of the statements included in the Pricing Disclosure Package and the Final Offering Memorandum (except to the
extent stated in paragraphs 10 and 11 above). Subject to the foregoing and on the basis of the information we gained in the course of performing the services referred to above, we advise you that: 

(a) the documents incorporated by reference in the Pricing Disclosure Package and the Final Offering Memorandum, when they were filed with the
Commission, appear on their face to be appropriately responsive in all material respects to the requirements of the Exchange Act; and 
 (b)
nothing came to our attention that caused us to believe that: 
 (A) the Pricing Disclosure Package, as of the Time of Sale,
included an untrue statement of a material fact or omitted 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; or 

(B) 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; 

it being understood that in each case we have not been asked to, and do not, express any belief with respect to (i) the financial statements and
schedules or other financial or accounting information contained or included or incorporated by reference therein or omitted therefrom, (ii) the summary reserve report of the independent petroleum engineer and reserve information contained or
included or incorporated by reference therein or omitted therefrom, or (iii) representations and warranties and other statements of fact contained in the exhibits to the documents incorporated by reference therein.

 ANNEX I 

Resale Pursuant to Regulation S or Rule 144A. Each Initial Purchaser understands that: 

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,
during such 40-day restricted period, it will not cause any advertisement with respect to the Securities (including any “tombstone” advertisement) to be published in any newspaper or periodical or posted in any public place and will not
issue any circular relating to the Securities, except such advertisements as are permitted by and include the statements required by Regulation S. 

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.”
