 Ladies and Gentlemen:

 Memorial Resource Development Corp., a Delaware corporation (the “Company”) confirms its agreement with each of the

aggregate principal amount of the Company’s 5.875% Senior Notes due 2022 (the “Notes”). The Notes will be issued pursuant to an Indenture, to be dated as of the Closing Date (as defined herein) (the
“Indenture”) among the Company, the Guarantors referred to below, and U.S. Bank National Association, as trustee (the “Trustee”). The Company’s obligations under the Notes, including the due and punctual
payment of interest on the Notes, will be irrevocably and unconditionally guaranteed on an unsecured senior basis (the “Guarantees” and, together with the Notes, the “Securities”) by the Guarantors. Certain terms
used in this purchase agreement (this “Agreement”) are defined in Section 15 hereof. 
 Reference herein to:
(i) “Guarantors” means each of the entities set forth on Exhibit B; (ii) “MRD Parties” means the Company and the Guarantors; (iii) “MRD Entities” means the MRD Parties and their
respective subsidiaries other than the Partnership and its subsidiaries; (iv) “Partnership” means Memorial Production Partners LP, a Delaware limited partnership; (v) “General Partner” means Memorial
Production Partners GP LLC, a Delaware limited liability company and the sole general partner of the Partnership; and (vi) “MRD Properties” means the properties and assets owned by the MRD Entities. 

The Securities will be offered and sold to the Initial Purchasers without registration under the 1933 Act, in reliance on the exemption
provided by Section 4(a)(2) of the 1933 Act. The MRD Parties have prepared a preliminary offering memorandum, dated June 23, 2014 (the “Preliminary Offering Memorandum”), and a pricing term sheet substantially in the form
attached hereto as Exhibit D (the “Pricing Term Sheet”) setting forth the terms of the Securities omitted from the Preliminary Offering Memorandum. Promptly following the execution of this Agreement, the MRD Parties will
prepare an offering memorandum, dated June 25, 2014 (the

“Offering Memorandum”), setting forth information regarding the MRD Entities and the Securities. The Preliminary Offering Memorandum, as supplemented and amended as of the
Applicable Time, together with the Pricing Term Sheet and any of the documents listed on Exhibit E hereto are collectively referred to as the “General Disclosure Package.” The MRD Parties hereby confirm that they have
authorized the use of the General Disclosure Package and the Offering Memorandum in connection with the offering and resale of the Securities by the Initial Purchasers. 

You have advised the Company that you will resell, in the case of (i) below, and offer and resell, in the case of (ii) below
(collectively, the “Exempt Resales”), the Securities purchased by you hereunder on the terms set forth in each of the General Disclosure Package and the Offering Memorandum, as amended or supplemented, solely to (i) persons
whom you reasonably believe to be “qualified institutional buyers” as defined in Rule 144A under the 1933 Act (“QIBs”), and (ii) in compliance with Regulation S under the 1933 Act (“Regulation S”).
Those persons specified in clauses (i) and (ii) of this paragraph are referred to herein as “Eligible Purchasers.” 

Holders (including subsequent transferees) of the Securities will have the benefit of the registration rights set forth in the registration
rights agreement substantially having the terms described in the General Disclosure Package among the MRD Parties and the Initial Purchasers to be dated the Closing Date (as defined herein). Pursuant to the Registration Rights Agreement, the MRD

reliance on Regulation S, and the Company, any affiliate of the Company and any person acting on its behalf (other than the Initial Purchasers, as to whom the MRD Parties make no representation) have complied with and will implement the
“offering restrictions” required by Rule 902 under the 1933 Act. 
 (8) No Integration. None of the MRD

MRD Properties disclosed in the General Disclosure Package and the Offering Memorandum were based are independent petroleum engineers with respect to the MRD Entities and for the periods set forth in the General Disclosure Package and the Offering
Memorandum. 
 (31) Oil and Natural Gas Reserves. The oil and natural gas reserve estimates of the MRD Properties
contained in the General Disclosure Package and the Offering Memorandum are derived from reports that have been prepared, and audits that have been completed, by Netherland, Sewell & Associates, Inc. (“NSAI”), and such
estimates fairly reflect, in all material respects, the oil and natural gas reserves attributable to such properties at the dates indicated therein and are in accordance, in all material respects, with Commission guidelines applied on a consistent
basis throughout the periods involved. 
 (32) Absence of Proceedings. Except as described in the General Disclosure
Package and the Offering Memorandum, no action, suit, proceeding, inquiry or investigation by or before any court or governmental or other regulatory or administrative agency, authority or body or any arbitrator involving any of the MRD Entities or

agencies or bodies necessary to conduct its business in the manner described in the General Disclosure Package and the Offering Memorandum, except for such Governmental Licenses the failure of which to obtain, would not result in, individually or in
the aggregate, a Material Adverse Effect; the MRD Entities are and will be in compliance with the terms and conditions of all such Governmental Licenses, except where the failure so to comply would not, individually or in the aggregate, have a
Material Adverse Effect; the Governmental Licenses are and will be valid and in full force and effect, except when the invalidity of such Governmental Licenses or the failure of such Governmental Licenses to be in full force and effect would not,
individually or in the aggregate, have a Material Adverse Effect; and, to the knowledge of the MRD Parties, none of the MRD Entities has received any notice of proceedings relating to the revocation or modification of any Governmental Licenses that,

in, individually or in the aggregate, a Material Adverse Effect; all policies of insurance and any fidelity or surety bonds insuring the MRD Entities or their respective businesses, assets, employees, officers and directors will be in full force and
effect, except when the failure of such policies of insurance and any fidelity or surety bonds to be in full force and effect would not, individually or in the aggregate, have a Material Adverse Effect; and the MRD Entities will be in compliance
with the terms of such policies and instruments in all material respects. 
 (37) No Restrictions on Distributions. No
MRD Entity is, and on the Closing Date, no MRD Entity will be, prohibited, directly or indirectly, from making any distribution with respect to its equity interests or from repaying any loans or advances to any other MRD Entity, except as described

amended, including the regulations and published governmental interpretations thereunder (“ERISA”); (ii) no “reportable event” (as defined in Section 4043(c) ERISA) has occurred with respect to any “pension

expect to incur, liability under (a) Title IV of ERISA with respect to termination of, or withdrawal from, any “pension plan” or (b) Sections 412 or 4971 of the Internal Revenue Code of 1986, as amended, including the
regulations and published governmental interpretations thereunder (the “Code”) with respect to any “pension plan”; (iv) each “pension plan” for which any MRD Entity would have any liability that is intended
to be qualified under Section 401(a) of the Code is the subject of a favorable determination or opinion letter from the Internal Revenue Service to the effect that it is so qualified and, to the knowledge of the MRD Parties, nothing has
occurred, whether by action or by failure to act, which could reasonably be expected to cause the loss of such qualification; and (v) no MRD Entity has incurred any material unpaid liability to the Pension Benefit Guaranty Corporation (other

Act); and (i) such disclosure controls and procedures are designed to ensure that the information required to be disclosed by the Company in the reports it files or will file or submit under the 1934 Act, as applicable, is accumulated and
communicated to management of the Company, including their respective principal executive officers and principal financial officers, as appropriate, and (ii) such disclosure controls and procedures are effective in all material respects to
perform the functions for which they were established to the extent required by Rule 13a-15 of the 1934 Act. 
 (45)
Absence of Manipulation. None of the MRD Entities has taken, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in, under the 1934 Act or otherwise, stabilization or
manipulation of the price of any security of the MRD Entities to facilitate the sale or resale of the Securities.

U.S. sanctions administered by OFAC.

their judgment, it is necessary) to amend or supplement the General Disclosure Package or the Offering Memorandum so that the General Disclosure Package or the Offering Memorandum, as the case may be, will not include any untrue statement of a

the conditions, contained in this Agreement, or as the Representative or counsel for the Initial Purchasers may otherwise reasonably request; and all proceedings taken by the Company or any Guarantor in connection with the issuance and sale of the

 (h) Termination of Agreement. If any condition specified in this Section 5 shall not
have been fulfilled when and as required to be fulfilled, this Agreement may be terminated by the Representative by notice to the MRD Parties at any time on or prior to the Closing Date and such termination shall be without liability of any party to

SECTION 6. Indemnification. 

(a) Indemnification by the MRD Parties. Each of the MRD Parties agrees, jointly and severally, to indemnify and hold harmless each
Initial Purchaser, its affiliates, and its and their officers, directors, employees, agents, partners and members and each person, if any, who controls any Initial Purchaser within the meaning of Section 15 of the 1933 Act or Section 20 of
the 1934 Act as follows: 
 (i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred,
arising out of or based upon any untrue statement or alleged untrue statement of a material fact in the Preliminary Offering Memorandum, any Issuer Free Writing Document, the General Disclosure Package or the Offering Memorandum (or any amendment or
supplement to any of the foregoing), or in any materials, presentations, information or any General Solicitation provided to investors by, or with the approval in writing of, any MRD Party in connection with the marketing of the offering of the
Securities, including any road show or investor presentations made to investors by the Company (whether in person or electronically), 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; 
 (ii) against any and all loss, liability,
claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of, or pursuant to a judgment or other disposition in, any litigation, or any investigation or proceeding by any governmental or
self-regulatory agency or body, commenced or threatened, or of any claim whatsoever arising out of or based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided, that (subject to Section 6(d)
below) any such settlement is effected with the written consent of the MRD Parties; and 
 (iii) against any and all expense
whatsoever (including the fees and disbursements of counsel) reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental or self-regulatory agency or body, commenced or
threatened, or any claim whatsoever arising out of or based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above, 

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of
or based upon any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the MRD Parties by any Initial Purchaser through the Representative


  
 23 







 
expressly for use in the Preliminary Offering Memorandum, any Issuer Free Writing Document, Permitted General Solicitation, the General Disclosure Package or the Offering Memorandum (or in any
amendment or supplement to any of the foregoing), it being understood and agreed that the only such information furnished by the Initial Purchasers as aforesaid consists of the information described as such in Section 6(b) hereof. 

(b) Indemnification by the Initial Purchasers. Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless
the MRD Parties, their respective directors and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all loss, liability, claim, damage and expense
described in the indemnity contained in subsection (a) of this Section 6, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Preliminary Offering Memorandum, any
Issuer Free Writing Document, Permitted General Solicitation or the Offering Memorandum (or any amendment or supplement to any of the foregoing), in reliance upon and in conformity with written information furnished to any MRD Party by any Initial
Purchaser through the Representative expressly for use therein. The MRD Parties hereby acknowledge and agree that the information furnished to any of the MRD Parties by the Initial Purchasers through the Representative expressly for use in the
General Disclosure Package, any Issuer Free Writing Document, General Solicitation consented to by the Company in writing or the Offering Memorandum (or any amendment or supplement to any of the foregoing), consists exclusively of the following
information appearing in the Preliminary Offering Memorandum and the Offering Memorandum: (i) the statements set forth in the last paragraph of the cover page regarding delivery of the Securities and (ii) under the heading “Plan of
Distribution,” the information found in the table in the first paragraph and in the third, ninth and tenth paragraphs. 
 (c)
Actions Against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder;
provided, however, that the failure so to notify the indemnifying party (i) will not relieve the indemnifying party from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and
such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification
obligation provided in paragraph (a) or (b) above. Counsel to the indemnified parties shall be selected as follows: counsel to the Initial Purchasers and the other indemnified parties referred to in Section 6(a) above shall be
selected by the Representative; and counsel to the MRD Parties, their respective directors, each of their respective officers and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20
of the 1934 Act shall be selected by the Company. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the
indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying party be liable for the fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for the Initial
Purchasers and the other indemnified parties referred to in Section 6(a) above; and the fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for the MRD Parties, their respective
directors, each of their respective officers and each person, if any, who controls 

  
 24 







 
the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, in each case in connection with any one action or separate but similar or related actions in
the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect
to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or
Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out
of such litigation, investigation, proceeding or claim 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) Settlement Without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party
to reimburse the indemnified party for fees and expenses of counsel as contemplated by this Section 6, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) effected
without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement
at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement. 

SECTION 7. Contribution. If the indemnification provided for in Section 6 hereof is for any reason unavailable to or
insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims,
damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the MRD Parties, 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) 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 MRD Parties, on the one hand, and of the Initial Purchasers, on the other hand, in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or
expenses, as well as any other relevant equitable considerations. 
 The relative benefits received by the MRD Parties, 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 MRD Parties and the total discounts and commissions received by the Initial Purchasers, in each case as determined pursuant to this Agreement, bear to the aggregate initial offering price
of the Securities as set forth on the cover of the Offering Memorandum. 
 The relative fault of the MRD Parties, 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


  
 25 







 
relates to information supplied by the MRD Parties, on the one hand, or by 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. 
 The MRD Parties and the Initial Purchasers agree that it would not be just
and equitable if contribution pursuant to this Section 7 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 above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any
legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim
whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission. 
 Notwithstanding the provisions of this
Section 7, no Initial Purchaser shall be required to contribute any amount in excess of an amount equal to the total discounts and commissions received by the Initial Purchaser pursuant to this Agreement by reason of any 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 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. 

For purposes of this Section 7, each affiliate, officer, director, employee, partner and member of each Initial Purchaser and each
person, if any, who controls any Initial Purchaser within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, shall have the same rights to contribution as such Initial Purchaser, and each director of each of the MRD
Parties, each officer of each of the MRD Parties, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, shall have the same rights to contribution as the MRD
Parties. The Initial Purchasers’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the principal amount of Notes set forth opposite their respective names in Exhibit A hereto and not joint.

 SECTION 8. Representations, Warranties and Agreements to Survive Delivery. All the respective representations, warranties,
indemnities and agreements of the MRD Parties and the Initial Purchasers shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Initial Purchaser or the MRD Parties, and shall survive
delivery of and payment for the Securities. 
 SECTION 9. Termination of Agreement. 

(a) Termination; General. The Representative may terminate this Agreement, by notice to the Company, at any time on or prior to the
Closing Date (i) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any declaration of a national emergency or war by the United States, any outbreak of
hostilities or escalation thereof or other calamity or crisis or any change or 

  
 26 







 
development involving a prospective change in national or international political, financial or economic conditions (including, without limitation, as a result of terrorist activities), in each
case the effect of which is such as to make it, in the judgment of the Representative, so material and adverse as to make it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities or to enforce contracts for
the sale of the Securities on the terms and in the manner contemplated in the General Disclosure Package and the Offering Memorandum, or (ii) (A) if trading in any securities of the Company has been suspended by the Commission or the Nasdaq
Global Market or (B) if trading generally on the NYSE, the Nasdaq Global Select Market or the Nasdaq Global Market has been suspended or limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been
required, by any of said exchanges or by order of the Commission or any other governmental authority or (iii) if a banking moratorium has been declared by either Federal or New York authorities. 

(b) Liabilities. If this Agreement is terminated pursuant to this Section 9, such termination shall be without liability of any
party to any other party except that the MRD Parties shall be obligated to reimburse the expenses of the Initial Purchasers as provided in Section 4 hereof, and except that Sections 1, 2(d), 6, 7, 8, 11, 12, 13, 14, 15, 17, 18, 19 and 20
hereof shall survive such termination and remain in full force and effect. 
 SECTION 10. Default by One or More of the Initial
Purchasers. If one or more of the Initial Purchasers shall fail at the Closing Date to purchase the aggregate principal amount of Securities which it or they are obligated to purchase under this Agreement (the “Defaulted
Securities”), the Representative shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Initial Purchasers, or any other purchaser, to purchase all, but not less than all, of the
Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representative shall not have completed such arrangements within such 24-hour period, then: 

(i) if the aggregate principal amount of Defaulted Securities does not exceed 10% of the aggregate principal amount of
Securities, each of the non-defaulting Initial Purchasers shall be obligated, severally and not jointly, to purchase the full amount of such Defaulted Securities in the proportions that their respective underwriting obligations hereunder bear to the
underwriting obligations of all non-defaulting Initial Purchasers; or 
 (ii) if the number of Defaulted Securities exceeds
10% of the aggregate principal amount of Securities, this Agreement shall terminate without liability on the part of any non-defaulting Initial Purchaser. 

No action taken pursuant to this Section 10 shall relieve any defaulting Initial Purchaser from liability in respect of its default. 

In the event of any such default which does not result in a termination of this Agreement, the Representative shall have the right to postpone
the Closing Date for a period not exceeding seven days in order to effect any required changes in the General Disclosure Package or Offering Memorandum or in any other documents or arrangements. As used herein, the term “Initial Purchaser”
includes any person substituted for an Initial Purchaser under this Section 10. 

  
 27 







 SECTION 11. Notices. All notices and other communications hereunder shall be in
writing, shall be effective only upon receipt and shall be mailed, delivered by hand or overnight courier, or transmitted by fax (with the receipt of any such fax to be confirmed by telephone). Notices to the Initial Purchasers shall be directed to

and their respective successors. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Initial Purchasers, the MRD Parties and their respective successors and the
controlling persons and other indemnified parties referred to in Sections 6 and 7 and their successors, heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein
contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Initial Purchasers, the MRD Parties and their respective successors, and said controlling persons and other indemnified

influenced by, their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Initial Purchasers’ research analysts may hold views and make statements or investment recommendations
and/or publish research reports with respect to the MRD Parties and/or the offering that differ from the views of their respective investment banking divisions. Each of the MRD Parties hereby waives and releases, to the fullest extent permitted by
applicable law, any claims that the MRD Parties may have against the Initial Purchasers arising from the fact that the views expressed by their research analysts and research departments may be different from or inconsistent with the views or advice
communicated to the MRD Parties by such Initial Purchasers’ investment banking divisions. Each of the MRD Parties also acknowledges that each of the Initial Purchasers is a full service securities firm and as such from time to time, subject to
applicable securities laws, may effect transactions for its own account or the account of its customers, may make recommendations and provide other advice, and may hold long or short positions in debt or equity securities of, or derivative products

Additional Changes to the Preliminary Memorandum: 

Summary – The Offering 
 On page 15 of the
Preliminary Memorandum, the second paragraph under the caption “Ranking” is hereby replaced in its entirety with the following: 
 “As of
March 31, 2014, on a pro forma basis after giving effect to this offering, the application of the net proceeds from this offering as described herein, and the other transactions described under “—Recent Developments,” the MRD
Segment would have had approximately $634.4 million of total indebtedness, approximately $34.4 million of which would be secured indebtedness under our senior secured revolving credit facility to which the notes would be effectively subordinated (to
the extent of the value of the assets securing such indebtedness), and we would have had approximately $634.1 million of additional borrowing capacity available after taking into account an anticipated reduction in the borrowing base in connection
with this offering, subject to compliance with financial covenants, for additional secured borrowings which would be effectively senior to the notes. In connection with the issuance of the notes, we expect the borrowing base under our senior secured
revolving credit facility to be automatically decreased by approximately $56.5 million.” 
 Summary Historical Consolidated and Combined Pro
Forma Financial Data 
 On page 21 of the Preliminary Memorandum, the net income (loss) row is adjusted as follows: MRD Segment Pro Forma net income
(loss) (in thousands) for the Year Ended December 31, 2013 is $(2,993) and for the Three Months Ended March 31, 2014 is $12,229.

revolving credit facility is $34,351, Senior Notes due 2022 offered hereby is $600,000, Total long-term debt is $1,622,786 and Total Capitalization is $2,483,930.

sale of the Notes by the Company to the Initial Purchasers or in connection with the offer, resale and delivery of the Notes by the Initial Purchasers in accordance with the terms of and in the manner contemplated by the Purchase Agreement and the
Final Offering Memorandum, it being expressly understood that we express no opinion in this paragraph 12 or paragraph 5 as to any subsequent offer or resale of any of the Notes. 


Our identification of documents and information as part of the Pricing Disclosure Package has been at your request and with your approval.
Such identification is for the limited purpose of making the statements set forth in this letter and is not the expression of a view by us as to whether any such information has been or should have been conveyed to investors generally or to any
particular investors at any particular time or in any particular manner. 
 Because the primary purpose of our professional engagement was
not to establish or confirm factual matters, financial, accounting or statistical information or reserve and production information, and because many determinations involved in the preparation of the Pricing Disclosure Package and the Final Offering
Memorandum are of a wholly or partially non-legal character, except as expressly set forth in paragraph 8 of this opinion letter, we are not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the
statements contained in the Pricing Disclosure Package and the Final Offering Memorandum and we make no representation that we have independently verified the accuracy, completeness or fairness of such statements. 

However, in the course of our acting as counsel to the Company in connection with the preparation of the Pricing Disclosure Package and the
Final Offering Memorandum, we have reviewed each such document and have participated in conferences and telephone conversations with representatives of the Company, representatives of the independent public accountants for the Company,
representatives of the independent reserve engineers for the applicable MRD Parties, representatives of the Initial Purchasers and representatives of the Initial Purchasers’ counsel, during which conferences and conversations the contents of
such documents and related matters were discussed. 
 Subject to the foregoing, on the basis of the information we gained in the course of
our participation in such conferences and conversations and our review of such documents, we confirm to you that no information has come to our attention that causes us to believe that (i) the Pricing Disclosure Package, as of 3:05 p.m. (New
York time) on June 25, 2014 (which you have informed us is a time prior to the time of the first sale of the Notes by any Initial Purchaser), 

  
 G-3 







 
contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they are
made, not misleading or (ii) the Final Offering Memorandum, as of its date and as of the Closing Date, contained or contains any untrue statement of a material fact or omitted or omits to state any material fact necessary in order to make the
statements therein, in the light of the circumstances under which they were made, not misleading, except that in the case of each of clauses (i)-(ii) above, we do not express any view as to the financial statements, the notes and schedules
thereto and other financial and accounting data and oil and gas reserve and production information contained therein or omitted therefrom.

 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 1933 Act. The 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 on 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.” 
 Such Initial Purchaser agrees that the Securities offered and sold in
reliance on Regulation S will be represented upon issuance by a temporary global security that may not be exchanged for definitive securities until the expiration of the 40-day restricted period referred to in Rule 903 of Regulation S and only upon
certification of beneficial ownership of such Securities by non-U.S. persons or U.S. persons who purchased such Securities in transactions that were exempt from the registration requirements of the 1933 Act.
