(c) (i) At the time of filing the Registration Statement, (ii) at the time of the most recent amendment thereto for the purposes of complying with Section 10(a)(3) of the Securities Act (whether such amendment was by post-effective amendment, incorporated report filed pursuant to Sections 13 or 15(d) of the Exchange Act or form of prospectus), (iii) at the time the Issuer or any person acting on its behalf (within the meaning, for this clause only, of Rule 163(c)) made any offer relating to the Shares in reliance on the exemption in Rule 163, and (iv) at the Applicable Time (with such date being used as the determination date for purposes of this clause (iv)), the Issuer was or is (as the case may be) a Well-Known Seasoned Issuer. The Issuer agrees to pay the fees required by the Commission relating to the Shares within the time required by Rule 456(b)(1) without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r).

(d) The documents incorporated by reference in the Registration Statement, the Prospectus and the Disclosure Package, at the respective times they were or hereafter are filed with the Commission, complied and will comply in all material respects with the requirements of the Exchange Act, and none of such documents contained any untrue statement

of a material fact or omitted to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; and any further documents so filed and incorporated by reference in the Registration Statement, the Prospectus or the Disclosure Package, when such documents are filed with the Commission will conform in all material respects to the requirements of the Exchange Act and will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(e) Each of the statements made by the Issuer in the Registration Statement, the Disclosure Package and the Prospectus regarding the Issuer’s expectations, plans and intentions, and any other information that constitutes “forward-looking” information within the meaning of the Securities Act and the Rules and Regulations was made or will be made with a reasonable basis and in good faith. Notwithstanding the foregoing, this representation and warranty shall not apply to any statements or omissions made in reliance upon and in conformity with written information furnished to the Issuer by the Underwriters expressly for use in the Registration Statement, any Preliminary Prospectus or the Prospectus.

(f) This Agreement has been duly authorized, executed and delivered by the Issuer, and constitutes a valid, legal, and binding obligation of the Issuer, enforceable in accordance with its terms, except as rights to indemnity and contributions hereunder may be limited by federal or state securities laws and except as such enforceability may be limited by bankruptcy, insolvency, reorganization or similar laws affecting the rights of creditors generally, and subject to general principles of equity. The Issuer has full power and authority to enter into and perform this Agreement.

(g) The Issuer has been duly organized and is validly existing as a corporation in good standing under the laws of the State of Texas with corporate power and authority to own or lease its properties and conduct its business as described in the Prospectus and the Disclosure Package. Each of the subsidiaries of the Issuer as listed in Exhibit A hereto (collectively, the “Subsidiaries”), has been duly organized or formed and is validly existing as a corporation, limited liability company or limited partnership, as applicable, in good standing under the laws of the jurisdiction of its incorporation, organization or formation with corporate, limited liability company or limited partnership power and authority to own or lease its properties and conduct its business as described in the Prospectus and the Disclosure Package. The Subsidiaries are the only subsidiaries (within the meaning of Regulation S-X), direct or indirect, of the Issuer. The Issuer 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 Issuer 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”).

(h) The information set forth under the caption “Capitalization” in the Prospectus and the Disclosure Package is true and correct (other than for subsequent issuances of capital stock, if any, pursuant to employee benefit plans described in the Disclosure Package and

the Prospectus or upon exercise of outstanding options or warrants described in the Disclosure Package and the Prospectus, as the case may be). All of the Shares conform to the description thereof contained in the Prospectus and the Disclosure Package. The outstanding shares of Common Stock of the Issuer have been duly authorized and validly issued and are fully paid and non-assessable. The outstanding shares of capital stock or other equity interests of each of the Subsidiaries have been duly authorized and validly issued, are fully paid (to the extent required under the applicable limited partnership agreement of such Subsidiary) and non-assessable (except as such non-assessability may be affected by Sections 153.102, 153.112, 153.202 or 153.210 of the Texas Business Organizations Code with respect to limited partnerships and Sections 101.114, 101.153 or 101.206 of the Texas Business Organizations Code with respect to limited liability companies) and, except as disclosed in the Prospectus and the Disclosure Package, are wholly owned by the Issuer or another Subsidiary free and clear of all liens, pledges, restrictions, encumbrances and equities and claims. The Shares to be issued and sold by the Issuer have been duly authorized and when issued and paid for as contemplated herein will be validly issued, fully paid and non-assessable.

(i) The form of certificates for the Shares conforms to the corporate law of the jurisdiction of the Issuer’s incorporation. Immediately after the issuance and sale of the Shares to the Underwriters, no shares of preferred stock of the Issuer shall be issued and outstanding and no holder of any shares of capital stock, securities convertible into or exchangeable or exercisable for capital stock or options, warrants or other rights to purchase capital stock or any other securities of the Issuer shall have any existing or future right to acquire any shares of preferred stock of the Issuer.

(j) No preemptive rights exist with respect to any of the Shares or the issue and sale thereof. Neither the filing of the Registration Statement nor the offering or sale of the Shares as contemplated by this Agreement gives rise to any rights, other than those which have been waived or satisfied, for or relating to the registration of any shares of Common Stock or other securities of the Issuer. Except as disclosed in the Prospectus and the Disclosure Package or otherwise granted pursuant to any employee benefit plans, qualified stock option plans, director compensation arrangements or the employee compensation plans of the Issuer and its Subsidiaries (collectively, the “Issuer Stock Plans”), no options, warrants or other rights to purchase, agreements or other obligations to issue or other rights to convert any obligations into shares of capital stock or ownership interests in the Issuer or its Subsidiaries are outstanding. All of the Issuer’s outstanding options, warrants or other rights to purchase or exchange any securities for shares of the Issuer’s capital stock have been duly authorized and validly issued, conform to the descriptions thereof contained in the Prospectus and Disclosure Package and were issued in compliance with federal securities laws and regulations and the terms of any applicable Issuer Stock Plans.

(k) The consolidated financial statements of the Issuer and the Subsidiaries, together with related notes and schedules as incorporated by reference in the Registration Statement, the Prospectus and the Disclosure Package, present fairly in all material respects the financial position and the results of operations and cash flows of the Issuer and the consolidated Subsidiaries, at the indicated dates and for the indicated periods. Such financial statements and related schedules have been prepared in accordance with U.S. generally accepted principles of accounting, consistently applied throughout the periods involved (“GAAP”), except as disclosed

therein, and all adjustments necessary for a fair presentation of results for such periods have been made. The summary financial and statistical data included in the Registration Statement, the Prospectus and the Disclosure Package presents fairly in all material respects the information shown therein and such data has been compiled on a basis consistent with the financial statements presented therein and the books and records of the Issuer. The unaudited pro forma financial statements included or incorporated by reference in the most recent Preliminary Prospectus include assumptions that provide a reasonable basis for presenting the significant effects directly attributable to the transactions and events described therein, the related pro forma adjustments give appropriate effect to those assumptions, and the pro forma adjustments reflect the proper application of those adjustments to the historical financial statement amounts in the unaudited pro forma financial statements included or incorporated by reference in the most recent Preliminary Prospectus. The unaudited pro forma financial statements included or incorporated by reference in the most recent Preliminary Prospectus comply as to form in all material respects with the applicable requirements of Regulation S-X under the Securities Act.

(l) The statistical, industry-related and market-related data included in the Registration Statement, the Prospectus and the Disclosure Package are based on or derived from sources that the Issuer reasonably and in good faith believes are reliable and accurate.

(m) The Issuer maintains a system of internal accounting controls (“Internal Controls”) sufficient to provide reasonable assurances that (i) transactions are executed in accordance with management’s general or specific authorization; (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain accountability for assets; (iii) access to assets is permitted only in accordance with management’s general or specific authorization; and (iv) the recorded accountability for assets is compared with existing assets at reasonable intervals and appropriate action is taken with respect to any differences.

(n) Since the date of the most recent balance sheet of the Issuer and its consolidated Subsidiaries reviewed or audited by KPMG LLP and reviewed by the audit committee of the board of directors of the Issuer, (i) the Issuer has not been advised of (A) any significant deficiencies in the design or operation of Internal Controls that could adversely affect the ability of the Issuer 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 Issuer 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.

(o) The Issuer has established and maintains “disclosure controls and procedures” (as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act); the Issuer’s “disclosure controls and procedures” are reasonably designed to ensure that all information (both financial and non-financial) required to be disclosed by the Issuer 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 Issuer’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 Issuer required under the Exchange Act with respect to such reports.

(p) KPMG LLP, which has delivered its opinion with respect to the audited financial statements and schedules of the Issuer incorporated by reference in the Registration Statement and the Prospectus, is an independent registered public accounting firm with respect to the Issuer within the meaning of the Securities Act and the Rules and Regulations and the applicable rules and regulations of the Public Company Accounting Oversight Board.

(q) Except as set forth in the Registration Statement, the Prospectus and the Disclosure Package, there is no action, suit, claim or proceeding pending or, to the knowledge of the Issuer, threatened against or affecting the Issuer or any of the Subsidiaries, before any court or administrative agency or which has the subject thereof any property owned or leased by the Issuer or any of the Subsidiaries (i) that are required to be described in the Registration Statement, the Prospectus or the Disclosure Package and are not so described or (ii) which, if determined adversely to the Issuer or any of its Subsidiaries, would reasonably be expected to have a Material Adverse Effect or prevent the consummation of the transactions contemplated hereby.

(r) No labor problem or dispute with the employees of the Issuer or the Subsidiaries exists or, to the Issuer’s knowledge, is threatened or imminent, and the Issuer 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.

(s) Each of the Issuer and its Subsidiaries has (i) good and defensible title to all of the oil and gas properties (including oil and gas xxxxx, producing leasehold interests and appurtenant personal property) owned by the Issuer and its Subsidiaries, title investigations having been carried out by the Issuer or its Subsidiaries consistent with the reasonable practice in the oil and gas industry in the areas in which the Issuer and its Subsidiaries operate and (ii) good title to all other real and personal property owned by the Issuer and its Subsidiaries, including but not limited to such other real and personal property reflected in the financial statements or as described in the Prospectus and Disclosure Package, 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 Prospectus and the Disclosure Package, (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 Issuer 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 Issuer 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 Issuer or any of its Subsidiaries holds or uses properties described in the Prospectus and the Disclosure Package are in full force and effect, with such

exceptions as would not reasonably be expected to have a Material Adverse Effect, and neither the Issuer 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 Issuer or its Subsidiaries under any of the leases or subleases mentioned above, or affecting or questioning the rights of the Issuer 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 Issuer reflect in all material respects the right of the Issuer to explore, develop or receive production from such real property, and the care taken by the Issuer 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 Issuer and its Subsidiaries operate for acquiring or procuring leases and interests therein to explore, develop or produce for hydrocarbons.

(t) The Issuer and its Subsidiaries have such consents, easements, rights-of-way or licenses from any person (“rights-of-way”) as are necessary to enable the Issuer and its Subsidiaries to conduct its business in the manner described in the Registration Statement, the Prospectus and the Disclosure Package, subject to such qualifications as may be set forth in the Registration Statement, Prospectus and the Disclosure Package, and except for such rights-of-way the lack of which would not have, individually or in the aggregate, a Material Adverse Effect.

(u) The Issuer 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 Disclosure Package or Prospectus. The Issuer 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 Issuer or sale by the Issuer of the Shares.

(v) Since the respective dates as of which information is given in the Registration Statement, the Prospectus and the Disclosure Package, as it may be amended or supplemented, (i) there has not been any material adverse change or any development involving a prospective change which has had or is reasonably likely to have a Material Adverse Effect, whether or not occurring in the ordinary course of business, and there has not been any material transaction entered into or any material transaction that is probable of being entered into by the Issuer or the Subsidiaries, other than transactions in the ordinary course of business and changes and transactions described in the Prospectus and the Disclosure Package, and (ii) none of the Issuer or any of its Subsidiaries 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 Issuer and its

Subsidiaries, 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 Issuer or its Subsidiaries, or any Material Adverse Effect, or any development involving or which may reasonably be expected to result in a Material Adverse Effect, in each case, except as described in the Prospectus and the Disclosure Package. The Issuer and the Subsidiaries have no material liabilities or obligations, or indirect or direct contingent obligations, that are not disclosed in or incorporated by reference in the Issuer’s financial statements in the Registration Statement and the Prospectus.

(w) Neither the Issuer nor any of the Subsidiaries is (i) in violation of its Certificate of Formation or other formation document (“Charter”) or Bylaws, limited partnership 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 Issuer or such Subsidiary or any of its properties, as applicable, except, with respect to clauses (i) through (iii), for such violations or defaults as would not, individually or in the aggregate, have a Material Adverse Effect. The execution and delivery of this Agreement 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 Issuer, (2) any contract, indenture, mortgage, deed of trust or other agreement or instrument to which the Issuer or any of the Subsidiaries is a party, or (3) any order, rule or regulation applicable to the Issuer or any of the Subsidiaries of any court or of any regulatory body or administrative agency or other governmental body having jurisdiction over the Issuer 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.

(x) 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 Issuer or any of the Subsidiaries or any of their respective properties or assets is required in connection with the offering, issuance or sale by the Issuer of the Shares or the execution, delivery and performance of this Agreement by the Issuer, 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 Issuer to consummate the transactions contemplated by this Agreement, and (iv) such Consents as are disclosed in the Disclosure Package and the Prospectus.

(y) The Issuer 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 Prospectus and the Disclosure Package 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 Issuer 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 Issuer 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.

(z) To the Issuer’s knowledge, there are no affiliations or associations between any member of Financial Industry Regulatory Authority (“FINRA”) and any of the Issuer’s officers, directors or 5% or greater security holders, except as set forth in the Registration Statement, the Prospectus and Disclosure Package. Except as disclosed in the Prospectus and the Disclosure Package, the Issuer (i) does not have any material lending or other relationship with the Underwriters or any bank or lending entity that is, to the Issuer’s knowledge, an affiliate of the Underwriters, and (ii) does not intend to use any of the proceeds from the sale of the Shares hereunder to repay any outstanding debt owed to any affiliate of the Underwriters.

(aa) The Issuer has not 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 the shares of Common Stock to facilitate the sale or resale of the Shares. The Issuer acknowledges that the Underwriters may engage in passive market making transactions in the Shares on the New York Stock Exchange in accordance with Regulation M under the Exchange Act.

(bb) Neither the Issuer nor any of the Subsidiaries is, and after giving effect to the offering and the sale of the Shares and the application of the proceeds thereof as described in the Prospectus and the Disclosure Package 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 “1940 Act”).

(cc) The Issuer and each of the Subsidiaries 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 Issuer or any Subsidiary or any of their respective businesses, assets, employees, officers and directors are in full force and effect, and the Issuer and the Subsidiaries are in compliance with the terms of such policies in all material respects. There are no claims by the Issuer or any Subsidiary under any such policy or instrument as to which an insurance company is denying liability or defending under a reservation of rights clause. The Issuer has no reason to believe that it or any Subsidiary 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.

(dd) The Issuer 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 Issuer would have any liability; the Issuer has not incurred and does not expect to incur liability under (i) Title IV of ERISA with respect to termination of, or withdrawal from, any “pension plan” or (ii) Section 412 or 4971 of the Internal Revenue Code of 1986, as amended, including the regulations and published interpretations thereunder (the “Code”); and each “pension plan” for which the Issuer would have any liability that is intended to be qualified under Section 401(a) of the Code is so qualified in all material respects and nothing has occurred, whether by action or by failure to act, which would cause the loss of such qualification.

(ee) Other than as contemplated by this Agreement or as disclosed in the Prospectus and the Disclosure Package, neither the Issuer nor any Subsidiary has incurred any liability for any finder’s or broker’s fee, or agent’s commission, in connection with the execution and delivery of this Agreement or the consummation of the transactions contemplated hereby.

(ff) Other than the Subsidiaries or as otherwise disclosed in the Prospectus and the Disclosure Package, the Issuer does not own, directly or indirectly, any shares of capital stock and does not have any other equity or ownership or proprietary interest in any corporation, partnership, association, trust, limited liability company, joint venture or other entity.

(gg) Neither the Issuer nor any Subsidiary 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 Issuer nor the Subsidiaries own or operate any real property contaminated with any substance that requires remedial action to be taken under any Environmental Laws, is liable for remedial action at any site where materials regulated under Environmental Laws were disposed by the Issuer or any Subsidiary, or is subject to any claim relating to any Environmental Laws, which violation, contamination, liability or claim in each case would individually or in the aggregate have a Material Adverse Effect; and the Issuer 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 Issuer 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 Issuer or its Subsidiaries) that would, individually or in the aggregate, have a Material Adverse Effect.

(hh) In the ordinary course of its business, the Issuer conducts a periodic review of the effect of applicable Environmental Laws on the business, operations and properties of the Issuer 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).

(pp) The operations of the Issuer and its Subsidiaries, and, to the knowledge of the Issuer and its Subsidiaries, the operations of any joint-ventures of the Issuer and its Subsidiaries, are and have been conducted at all times in compliance with all applicable financial recordkeeping and reporting requirements, including those of the Bank Secrecy Act, as amended by Title III of the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (USA PATRIOT Act), and the applicable anti-money laundering statutes of jurisdictions where such entities conduct business, the rules and regulations thereunder and any related or similar rules, regulations or guidelines, issued, administered or enforced by any governmental agency (collectively, the “Anti-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 Issuer or any of its Subsidiaries or, to the knowledge of the Issuer, involving any joint-venture of the Issuer and its Subsidiaries, with respect to the Anti-Money Laundering Laws is pending or, to the knowledge of the Issuer, threatened.

(qq) None of the Issuer nor any of its Subsidiaries (collectively, the “Entity”), nor any director or officer of the Entity nor, to the Entity’s knowledge, any employee agent, affiliate, joint-venture or representative of the Entity, is an individual or entity (“Person”) that is, or is owned or controlled by, a Person that is (i) the subject of any sanctions administered or enforced by the U.S. Department of Treasury’s Office of Foreign Assets Control, the United Nations Security Council, the European Union, Her Majesty’s Treasury, 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 information underlying the estimates of the Issuer’s reserves that was supplied to Netherland, Xxxxxx & Associates, Inc. (the “Reserve Engineer”), for the purposes of auditing the reserve reports and estimates of the proved reserves of the Issuer disclosed in the Registration Statement, the Prospectus and the Disclosure Package, 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 Registration Statement, the Prospectus and the Disclosure Package, the Issuer 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 Registration Statement, the Prospectus and the Disclosure Package and as reflected in the reports the Reserve Engineer prepared with regard to the proved reserves that the Issuer owns.

The Underwriters represent and agree that they have not made and, without the prior consent of the Issuer, they will not make, any offer relating to the Shares that would constitute an Issuer Free Writing Prospectus.

The Issuer has complied and will comply with the requirements of Rule 433 of the Rules and Regulations applicable to any Issuer Free Writing Prospectus, including timely filing with the Commission or retention where required and legending. The Issuer agrees that if at any time following issuance of an Issuer Free Writing Prospectus any event occurred or occurs as a result of which such Issuer Free Writing Prospectus would conflict with the information in the Registration Statement, any Preliminary Prospectus or the Prospectus or would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in light of the circumstances then prevailing, not misleading, the Issuer will give prompt

The Issuer shall use its commercially reasonable efforts to prevent the issuance of any such stop order or notice of prevention or suspension of such use.

(i) to indemnify and hold harmless the Underwriters and their directors, officers, partners, members, employees, agents and each person, if any, who controls the Underwriters within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and the successors and assigns of each of the foregoing (each an “Indemnified Party”), against any losses, claims, expenses, damages or liabilities to which such Indemnified Party may become subject under the Securities Act or otherwise, insofar as such losses, claims, expenses, damages or liabilities (or actions or proceedings in respect thereof) arise out of or are based upon (x) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, the Preliminary Prospectus, the Disclosure Package, the Prospectus or any amendment or supplement thereto, or in any Issuer Free Writing Prospectus not included in the Disclosure Package, any “issuer information” filed or required to be filed pursuant to Rule 433(d) of the Rules and Regulations or any “road show” (as defined in Rule 433 of the Rules and Regulations) not constituting an Issuer Free Writing Prospectus, or (y) 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; provided, that the Issuer will not be liable to the Underwriters and their directors, officers, partners, members, employees, agents and each person, if any, who controls the Underwriters within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and the successors and assigns of each of the foregoing, in any such case to the extent that any such loss, claim, expense, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement made in, or omission or alleged

omission from any of such documents or any road show in reliance upon and in conformity with written information furnished to the Issuer by the Underwriters specifically for use therein, which information is specified in Section 13 below;

(ii) to reimburse each Indemnified Party upon demand for any and all legal or other out-of-pocket expenses reasonably incurred by such Indemnified Party in connection with investigating, settling, compromising, paying or defending any such loss, claim, expense, damage or liability, action or proceeding or in responding to a subpoena or governmental inquiry related to the offering of the Shares under Section 8(a)(i) above, whether or not such Indemnified Party is a party to any action or proceeding. In the event that it is finally judicially determined that the Underwriters are not entitled to receive payments for legal and other expenses pursuant to this subparagraph, the Underwriters will promptly return all sums that had been advanced pursuant hereto; and

(iii) the indemnification agreement set forth in this Section 8(a) shall be in addition to any liabilities that the Issuer may otherwise have.

(b) The Underwriters agree:

(i) to indemnify and hold harmless the Issuer, each of its directors, each of its officers who have signed the Registration Statement and each person, if any, who controls the Issuer within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (each, an “Underwriter Indemnified Party”), against any losses, claims, expenses, damages or liabilities to which such Underwriter Indemnified Party may become subject under the Securities Act or otherwise, insofar as such losses, claims, expenses, damages or liabilities (or actions or proceedings in respect thereof) arise out of or are based upon (x) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, the Preliminary Prospectus, the Disclosure Package, the Prospectus or any amendment or supplement thereto, or in any Issuer Free Writing Prospectus not included in the Disclosure Package or (y) 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; provided, that the Underwriters will be liable in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission has been made in such documents in reliance upon and in conformity with written information furnished to the Issuer by the Underwriters specifically for use therein, which information is specified in Section 13 below;

(ii) to reimburse each Underwriter Indemnified Party upon demand for any and all legal or other out-of-pocket expenses reasonably incurred by such Underwriter Indemnified Party in connection with investigating, settling, compromising, paying or defending any such loss, claim, expense, damage or liability, action or proceeding under Section 8(b)(i) above, whether or not such Underwriter Indemnified Party is a party to any action or proceeding. In the event that it is finally judicially determined that the Underwriter Indemnified Party was not entitled to receive payments for legal and other expenses pursuant to this subparagraph, the Underwriter Indemnified Party will promptly return all sums that had been advanced pursuant hereto; and

(iii) the indemnification agreement set forth in this Section 8(b) shall be in addition to any liabilities that the Underwriters may otherwise have.

(c) In case any proceeding (including any governmental investigation), action or suit shall be instituted involving any person in respect of which indemnity may be sought pursuant to this Section 8, such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing. No indemnification provided for in Section 8(a) or (b) shall be available to any party who shall fail to give notice as provided in this Subsection if the party to whom notice was not given was unaware of the proceeding to which such notice would have related and was materially prejudiced by the failure to give such notice, but the failure to give such notice shall not relieve the indemnifying party or parties from any liability which it or they may have to the indemnified party for contribution or otherwise than on account of the provisions of Section 8(a) or (b). In case any such proceeding shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party and shall pay as incurred the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel at its own expense. Notwithstanding the foregoing, the indemnifying party shall pay as incurred (or within 30 days of presentation) the fees and expenses of the counsel retained by the indemnified party in the event (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them or (iii) the indemnifying party shall have failed to assume the defense and employ counsel acceptable to the indemnified party within a reasonable period of time after notice of commencement of the action.

It is understood that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate firm (in addition to special local counsel) for all such indemnified parties. The indemnifying party 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 from and against any loss or liability by reason of such settlement or judgment. In addition, the indemnifying party will not, without the prior written consent of the indemnified party, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding of which indemnification may be sought hereunder (whether or not any indemnified party is an actual or potential party to such claim, action or proceeding) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action or proceeding and does not include a statement attributing fault or liability to any indemnified party.

(d) If the indemnification provided for in this Section 8 is unavailable to or insufficient to hold harmless an indemnified party under Section 8(a), (b) or (c) above in respect of any losses, claims, expenses, damages or liabilities (or actions or proceedings in respect

thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, expenses, damages or liabilities (or actions or proceedings in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Issuer on the one hand and the Underwriters on the other from the offering of the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Issuer on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, expenses, damages or liabilities, (or actions or proceedings in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Issuer on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Issuer (as set forth in the first paragraph of the cover page of the Prospectus) bear to the total underwriting discounts and commissions received by the Underwriters. The relative fault 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 Issuer on the one hand or the Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Issuer and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Subsection were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this Subsection. The amount paid or payable by an indemnified party as a result of the losses, claims, expenses, damages or liabilities (or actions or proceedings in respect thereof) referred to above in this Subsection shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Subsection, (i) the Underwriters shall not be required to contribute any amount in excess of the underwriting discounts and commissions applicable to the Shares purchased by the Underwriters and (ii) 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.

(e) Any losses, claims, expenses, damages or liabilities for which an indemnified party is entitled to indemnification or contribution under this Section 8 shall be paid by the indemnifying party to the indemnified party as such losses, claims, expenses, damages or liabilities are incurred. The indemnity and contribution agreements contained in this Section 8 and the representations and warranties of the Issuer set forth in this Agreement shall remain operative and in full force and effect, regardless of (i) any investigation made by or on behalf of the Underwriters or any person controlling the Underwriters, the Issuer, its directors or officers or any persons controlling the Issuer, (ii) acceptance of any Shares and payment therefor hereunder, and (iii) any termination of this Agreement. A successor to the Underwriters, or to the Issuer, its directors or officers, or any person controlling the Issuer, shall be entitled to the benefits of the indemnity, contribution and reimbursement agreements contained in this Section 8.

9. DEFAULT BY UNDERWRITERS.

If on the Closing Date any Underwriter shall fail to purchase and pay for the portion of the Shares which such Underwriter has agreed to purchase and pay for on such date (otherwise than by reason of any default on the part of the Issuer), you, as the Representative of the Underwriters, shall use your reasonable efforts to procure within 36 hours thereafter one or more of the other Underwriters, or any others, to purchase from the Issuer such amounts as may be agreed upon and upon the terms set forth herein, the Shares, which the defaulting Underwriter or Underwriters failed to purchase. If during such 36 hours you, as such Representative, shall not have procured such other Underwriters, or any others, to purchase the Shares, agreed to be purchased by the defaulting Underwriter or Underwriters, then (a) if the aggregate number of shares with respect to which such default shall occur does not exceed 10% of the Shares, covered hereby, the other Underwriters shall be obligated, severally, in proportion to the respective numbers of Shares which they are obligated to purchase hereunder, to purchase the Shares which such defaulting Underwriter or Underwriters failed to purchase, or (b) if the aggregate number of Shares with respect to which such default shall occur exceeds 10% of the Shares covered hereby, the Issuer or you as the Representative of the Underwriters will have the right to terminate this Agreement without liability on the part of the non-defaulting Underwriters or of the Issuer except to the extent provided in Section 8 hereof. In the event of a default by any Underwriter or Underwriters, as set forth in this Section 9, the Closing Date may be postponed for such period, not exceeding seven days, as you, as Representative, may determine in order that the required changes in the Registration Statement or in the Prospectus or in any other documents or arrangements may be effected. The term “Underwriter” includes any person substituted for a defaulting Underwriter. Any action taken under this Section 9 shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

11. TERMINATION. This Agreement may be terminated:

(a) by you at any time prior to the Closing Date if any of the following has occurred: (i) since the respective dates as of which information is given in the Registration Statement and the Prospectus, any material adverse change or any development involving a prospective change, which in the absolute discretion of the Underwriters, has had, or is reasonably likely to have, a Material Adverse Effect, (ii) any outbreak, attack, or escalation of hostilities or declaration of war, national emergency, act of terrorism or other national or international calamity or crisis or change in economic, financial or political conditions if the effect of such outbreak, escalation, declaration, emergency, calamity, crisis or change on the financial markets of the United States or Canada would, in the absolute discretion of the Underwriters make it impracticable or inadvisable to market the Shares or to enforce contracts for the sale of the Shares, (iii) suspension of trading in securities generally on the New York Stock Exchange or limitation on prices (other than limitations on hours or numbers of days of trading) for securities on such exchange, (iv) the enactment, publication, decree or other promulgation of any statute, regulation, rule or order of any court or other governmental authority which in your opinion materially and adversely affects or may materially and adversely affect the business or operations of the Issuer, (v) declaration of a banking moratorium by United States or New York State authorities, (vi) any downgrading, or placement on any watch list for possible downgrading, in the rating of the Issuer’s debt securities by any “nationally recognized statistical rating organization” (as defined for purposes of Rule 436(g) under the Exchange Act), (vii) the suspension of trading of the Issuer’s Common Stock by the New York Stock Exchange, the Commission, or any other governmental authority, or (viii) the taking of any action by any governmental body or agency in respect of its monetary or fiscal affairs which in your reasonable opinion has a material adverse effect on the securities markets in the United States; or

(b) as provided in Sections 6 and 7 of this Agreement.

12. SUCCESSORS.

This Agreement has been and is made solely for the benefit of the Issuer and the Underwriters and their respective successors, executors, administrators, heirs and assigns, and the officers, directors and controlling persons referred to herein, and no other person will have any right or obligation hereunder. No purchaser of any of the Shares from the Underwriters shall be deemed a successor or assign merely because of such purchase.

13. INFORMATION PROVIDED BY UNDERWRITERS.

The Issuer and the Underwriters acknowledge and agree that the only information furnished or to be furnished by the Underwriters to the Issuer for inclusion in any Preliminary Prospectus, Prospectus, Issuer Free Writing Prospectus or the Registration Statement consists of (a) the statement regarding delivery of shares by the Underwriters set forth on the cover page of, and (b) the third, thirteenth and fourteenth paragraphs under the caption “Underwriting” in the Prospectus.

14. RESEARCH INDEPENDENCE.

In addition, the Issuer acknowledges that the Underwriters’ research analysts and research department is required to be independent from its investment banking division and is subject to certain regulations and internal policies, and that the Underwriters’ research analysts may hold and make statements or investment recommendations and/or publish research reports with respect to the Issuer and/or the offering that differ from the views of its investment bankers. The Issuer hereby waives and releases, to the fullest extent permitted by law, any claims that the Issuer may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by its independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Issuer by the Underwriters’ investment banking division. The Issuer acknowledges that the Underwriters are full service securities firms and as such from time to time, subject to applicable securities laws, may effect transactions for their own account or the account of their customers and hold long or short position in debt or equity securities of the companies which may be the subject to the transactions contemplated by this Agreement.

15. NO FIDUCIARY DUTY.

Notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Underwriters, the Issuer acknowledges and agrees that:

(a) nothing herein shall create a fiduciary or agency relationship between the Issuer and the Underwriters;

(b) the Underwriters are not acting as an advisor, expert or otherwise, to the Issuer in connection with this offering, sale of the Shares or any other services the Underwriters may be deemed to be providing hereunder, including, without limitation, with respect to the public offering price of the Shares;

(c) the relationship between the Issuer and the Underwriters is entirely and solely commercial, based on arms-length negotiations;

(d) any duties and obligations that the Underwriters may have to the Issuer shall be limited to those duties and obligations specifically stated herein; and

(e) notwithstanding anything in this Underwriting Agreement to the contrary, the Issuer acknowledges that the Underwriters may have financial interests in the success of the offering that are not limited to the difference between the price to the public and the purchase price paid to the Issuer by the Underwriters for the shares and the Underwriters have no obligation to disclose, or account to the Issuer for, any of such additional financial interests.

The Issuer hereby waives and releases, to the fullest extent permitted by law, any claims that the Issuer may have against the Underwriters with respect to any breach or alleged breach of fiduciary duty.

16. MISCELLANEOUS.

The reimbursement, indemnification and contribution agreements contained in this Agreement and the representations, warranties and covenants in this Agreement shall remain in full force and effect regardless of (a) any termination of this Agreement, (b) any investigation made by or on behalf of the Underwriters or controlling person thereof, or by or on behalf of the Issuer or its directors or officers and (c) delivery of and payment for the Shares under this Agreement.

FORM OF LEGAL OPINION OF XXXXXX, XXXX & XXXXXXXX LLP

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

2. Each subsidiary listed on Annex A (a “Subsidiary”) is a validly existing corporation, limited liability company or limited partnership in good standing under the laws of the State of Texas.

3. The Company has an authorized capitalization as set forth in the Prospectus. The Shares have been duly authorized and, when issued and delivered to and paid for by the Underwriters in accordance with the terms of the Underwriting Agreement, will be validly issued, fully paid and nonassessable. The issuance of the Shares is not subject to any preemptive rights under the Amended and Restated Certificate of Formation (the “Certificate of Formation”) or the Amended and Restated Bylaws (the “Bylaws”) of the Company.

4. The Company has all requisite corporate power to execute and deliver the Underwriting Agreement and to perform its obligations thereunder. The execution and delivery by the Company of the Underwriting Agreement and the performance of its obligations thereunder have been duly authorized by all necessary corporate action. The Underwriting Agreement has been duly executed and delivered by the Company.

5. The execution and delivery by the Company of the Underwriting Agreement, the performance of its obligations thereunder, and the issuance by the Company of the Shares to the Underwriters:

(i)

do not and will not violate the Certificate of Formation or Bylaws of the Company;

(ii)

based solely upon review of such agreements, do not and will not result in a breach of or default under any agreement to which the Company is a party that is identified to us in a certificate of the Company as being material to the Company and its subsidiaries taken as a whole, which agreements are listed on Annex B; and

(iii)

do not and will not (A) violate, or require any filing with or approval of any governmental authority or regulatory body of the State of New York or Texas or the United States of America under, any law, rule or regulation of the State of New York or Texas or the United States of America applicable to the Company that, in

B-1

our experience, is generally applicable to transactions in the nature of those contemplated by the Underwriting Agreement or (B) require any filing with or approval of any governmental authority or regulatory body of the United States of America under the Securities Act of 1933, as amended (the “Securities Act”), except for such filings or approvals as already have been made or obtained.

6. Insofar as the statements in the Prospectus under the caption “Description of Common Stock” and “Underwriting” purport to summarize the documents referred to therein, such statements fairly present in all material respects the information required to be disclosed under the Securities Act and the rules and regulations of the commission relating to registration statements on Form S-3 and prospectuses.

7. Insofar as the statements in the Prospectus under the caption “Material United States Federal Income Tax Considerations for Non-U.S. Holders” purport to summarize matters of United States federal tax law and regulations, such statements are accurate in all material respects, subject to the limitations, qualifications and assumptions set forth therein.

8. The Company is not and, after giving effect to the sale of the Shares and the use of proceeds therefrom as described in the Prospectus, will not be an “investment company” that is required to be registered under the Investment Company Act of 1940, as amended (the “Investment Company Act”). For purposes of this paragraph 8, the term “investment company” has the meanings ascribed to such term in the Investment Company Act.

FORM OF NEGATIVE ASSURANCE OF XXXXXX, XXXX & XXXXXXXX LLP

We have participated in conferences with officers and other representatives of the Company, representatives of the independent auditors and independent petroleum engineer of the Company and your representatives and counsel at which the contents of the Registration Statement, the General Disclosure Package and the Prospectus and related matters were discussed. Because the purpose of our professional engagement was not to establish or confirm factual matters and because we did not independently undertake to verify the accuracy, completeness or fairness of the statements set forth in the Registration Statement, the General Disclosure Package or the Prospectus, we are not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the General Disclosure Package or the Prospectus except insofar as such statements specifically relate to us or as specifically addressed in paragraphs 6 and 7 of our legal opinion addressed to you of even date herewith. Our identification of information as constituting the General Disclosure Package is for the limited purpose of making the statements set forth in this letter. We express no opinion or belief as to the conveyance of the General Disclosure Package or the Prospectus or the information contained therein to investors generally or to any particular investors at any particular time or in any particular manner.

On the basis of the foregoing, and except for (1) the financial statements and schedules and other information of an accounting or financial nature included or incorporated by reference therein, and (2) the summary reserve report of the independent petroleum engineer and any information derived therefrom, as to all of which we express no opinion or belief, no facts have come to our attention that led us to believe: (a) that the Registration Statement, at the time it became effective, or the Prospectus, as of the date of the Final Prospectus Supplement, were not appropriately responsive in all material respects to the requirements of the Securities Act and the applicable rules and regulations of the Commission thereunder; or (b)(i) that the Registration Statement, at the time it became effective, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) that the General Disclosure Package, at the Applicable Time, included an untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading or (iii) that the Prospectus, 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.

We assume no obligation to revise or supplement this letter in the event of any changes in law or fact arising after the date hereof. The statements made in this letter are solely for your benefit in connection with the transactions contemplated by the Underwriting Agreement and are not to be used for any other purpose or circulated, quoted or otherwise referred to without, in each case, our written permission.

Ladies and Gentlemen:

This letter is being delivered to you as representative (the “Representative”) of the several Underwriters (the “Underwriters”) in connection with the proposed Underwriting Agreement (the “Underwriting Agreement”), between Matador Resources Company (the “Issuer”) and the Representative, relating to an underwritten public offering of the Issuer’s common stock, $0.01 par value (the “Common Stock”).

In order to induce the Underwriters to enter into the Underwriting Agreement, the undersigned will not, without the prior written consent of the Representative, offer, sell, contract to sell or otherwise dispose of (or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by the undersigned or any affiliate of the undersigned or any person in privity with the undersigned or any affiliate of the undersigned), directly or indirectly, including the filing (or participation in the filing) of a registration statement with the Securities and Exchange Commission in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Securities and Exchange Commission promulgated thereunder with respect to, any Common Stock of the Issuer or any securities convertible into, or exercisable or exchangeable for such Common Stock (collectively, “Securities”), or publicly announce an intention to effect any such transaction, for a period of 60 days after the date of the Underwriting Agreement.

Notwithstanding the foregoing, the undersigned shall be permitted to (i) transfer Securities as a bona fide gift, (ii) transfer Securities to family members or a trust established for the benefit of family members, (iii) transfer Securities to entities where the undersigned is the sole beneficial owner of all Securities held by such entities, (iv) receive Securities upon the exercise of an option or warrant or in connection with the vesting of restricted stock or restricted stock units, and any Securities issued upon any such exercise or vesting shall be subject to the

restrictions contained in this agreement, (v) transfer Securities to the Issuer in a transaction exempt from Section 16(b) of the Exchange Act solely in connection with the payment of taxes due in connection with any exercise or vesting of Securities; provided, however, that in any such case described in clauses (i) through (v) it shall be a pre-condition to such transfer that the transferee or donee executes and delivers to the Representative a lock-up agreement in form and substance satisfactory to the Underwriters and (vi) transfer Securities pursuant to the terms of any pledge or collateral agreement existing on the date hereof.

If for any reason the Underwriting Agreement shall be terminated prior to the Closing Date (as defined in the Underwriting Agreement), the agreement set forth above shall likewise be terminated.

Yours very truly,
