Section 2.     Purchase, Sale and Delivery of the Securities.

(a)    The Firm Shares.  The Company agrees to issue and sell to the Underwriters the Firm Shares upon the terms set forth herein. On the basis of the representations, warranties and agreements contained herein, and upon the terms but subject to the conditions set forth herein, the Underwriters agree, severally and not jointly, to purchase from the Company the respective number of Firm Shares set forth opposite their names on Schedule A. The purchase price to be paid by the Underwriters to the Company for the Firm Shares shall be $2.28 per share (reflecting underwriting discounts and commissions of $0.12 per share from the public offering price of $2.40 per share).

(b)    The First Closing Date.  Delivery of the Firm Shares to be purchased by the Underwriters and payment therefor shall be made at the offices of Porter Hedges LLP at 1000 Main Street, Houston, Texas 77002 (or such other place as may be agreed to by the Company and the Representative) at 9:00 a.m. Houston time, on January 25, 2017, or such other time and date as shall be agreed upon by the Representative and the Company (the time and date of such closing are called the “First Closing Date”).

(c)    The Optional Shares; Option Closing Date.  In addition, on the basis of the representations, warranties and agreements contained herein, and upon the terms but subject to the conditions set forth herein, the Company hereby grants an option to the several Underwriters to purchase up to an aggregate of 3,750,000 Optional Shares from the Company at the purchase price per share to be paid by the Underwriters for the Firm Shares. The option granted hereunder is for use by the Underwriters solely in covering any over-allotments in connection with the sale and distribution of the Firm Shares. The option granted hereunder may be exercised at any time and from time to time in whole or in part upon notice by the Representative to the Company, which notice may be given at any time within 30 days from the date of this Agreement. Such notice shall set forth (i) the aggregate number of Optional Shares as to which the Underwriters are exercising the option, (ii) the names and denominations in which the Optional Shares are to be registered and (iii) the time, date and place at which the Optional Shares will be delivered (which time and date may be simultaneous with, but not earlier than, the First Closing Date; and in such case the term

“First Closing Date” shall refer to the time and date of delivery of certificates for the Firm Shares and such Optional Shares). Such time and date of delivery, if subsequent to the First Closing Date, is called an “Option Closing Date” and shall be determined by the Representative and shall not be earlier than two or later than five full business days after delivery of such notice of exercise. If any Optional Shares are to be purchased, each Underwriter agrees, severally and not jointly, to purchase the number of Optional Shares (subject to such adjustments to eliminate fractional shares as the Representative may determine) that bears the same proportion to the total number of Optional Shares to be purchased as the number of Firm Shares set forth on Schedule A opposite the name of such Underwriter bears to the total number of Firm Shares. The Representative may cancel the option at any time prior to its expiration by giving written notice of such cancellation to the Company.

(d)    Public Offering of the Securities.  The Representative hereby advises the Company that the Underwriters intend to offer for sale to the public, initially on the terms set forth in the Time of Sale Prospectus and the Prospectus, the Securities as soon after this Agreement has been executed as the Representative, in its sole judgment, has determined is advisable and practicable.

(e)    Payment for the Securities.  Payment for the Firm Shares shall be made at the First Closing Date by wire transfer of immediately available funds in U.S. dollars to the order of the Company. Payment for the Optional Shares shall be made at the First Closing Date or the applicable Option Closing Date, as the case may be, by wire transfer of immediately available funds in U.S. dollars to the order of the Company.

It is understood that the Representative has been authorized, for its own account and the accounts of the several Underwriters, to accept delivery of and receipt for, and make payment of, the purchase price for, the Firm Shares and any Optional Shares the Underwriters have agreed to purchase.

(f)    Delivery of the Securities.  The Company, through the facilities of DTC, shall deliver, or cause to be delivered, to the Representative for the accounts of the several Underwriters the Firm Shares at the First Closing Date against the irrevocable release of a wire transfer of immediately available funds for the amount of the purchase price therefor. The Company, through the facilities of DTC, shall deliver, or cause to be delivered, to the Representative for the accounts of the several Underwriters the Optional Shares the Underwriters have agreed to purchase at the First Closing Date or the applicable Option Closing Date, as the case may be, against the irrevocable release of a wire transfer of immediately available funds for the amount of the purchase price therefor. At least two full business days prior to the First Closing Date (or the applicable Option Closing Date, as the case may be), the Company shall authorize the Company’s transfer agent to arrange for the delivery of the Securities in accordance with the provisions of this Section 2(f). The Securities shall be registered as the Representative shall have requested at least one business day prior to the First Closing Date (or the applicable Option Closing Date, as the case may be). Time shall be of the essence and delivery at the time and place specified in this Agreement is a further condition to the obligations of the Underwriters.

(g)    Financial Statements. The historical consolidated financial statements of the Company filed with the Commission and included or incorporated by reference in the Registration Statement, the Preliminary Prospectus, the Prospectus and the Time of Sale Prospectus, present fairly in all material respects the financial condition of the Company and each of the subsidiaries of the Company identified in Schedule D (each, a “Subsidiary,” and together, the “Subsidiaries”) as of and at the dates indicated, as

applicable, and the consolidated statements of operations and cash flows of the Company and the Subsidiaries for the periods specified; such financial statements have been prepared in conformity with generally accepted accounting principles in the United States of America (“GAAP”) applied on a consistent basis throughout the periods involved except to the extent disclosed in the notes thereto. There are no financial statements (historical or pro forma) that are required to be included in the Registration Statement, the Preliminary Prospectus, the Prospectus or the Time of Sale Prospectus that are not included as required.

(h)    Disclosure Controls and Procedures and Internal Accounting.  The Company and each of its Subsidiaries has established and maintains disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) that (i) are designed to ensure that material information relating to the Company is made known to the Company’s principal executive officer and its principal financial officer by others within the Company, particularly during the periods in which the periodic reports required under the Exchange Act are being prepared; (ii) have been evaluated for effectiveness as of a date within 90 days prior to the earlier of the date that the Company filed its most recent annual or quarterly report with the Commission and the date of the Time of Sale Prospectus; and (iii) are effective in all material respects to perform the functions for which they were established. The Company and each of its Subsidiaries also maintain a system of “internal control over financial reporting” (as defined in Rule 13a-15(f) of the Exchange Act) that complies with the requirements of the Exchange Act and has been designed by, or under the supervision of, its principal executive and principal financial officers, or persons performing similar functions, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP. There has been no (i) significant deficiency or material weaknesses in the design or operation of internal controls over financial reporting that are reasonably likely to adversely affect the registrant’s ability to record, process, summarize and report financial information or (ii) fraud, whether or not material, that involves executive officers or other employees who have a significant role in the Company’s internal controls over financial reporting. The Company and each of its Subsidiaries maintain a system of internal accounting controls sufficient to provide reasonable assurance that (i) transactions are executed in accordance with management’s general or specific authorizations; (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP as applied in the United States and to maintain asset accountability; (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 the existing assets at reasonable intervals and appropriate action is taken with respect to any differences.

(i)    No Material Adverse Change in Business. Except as disclosed in the Preliminary Prospectus, Prospectus or the Time of Sale Prospectus, subsequent to the respective dates as of which information is given in the Time of Sale Prospectus, there has been no (i) material adverse change in the condition, financial or otherwise, or in the earnings, business, results of operations or prospects of the Company and its Subsidiaries, taken as a whole (the “Enterprise”), whether or not arising in the ordinary course of business, but excluding any changes in the oil and gas industry or the national or world economy generally that have not disproportionately affected the Company and its Subsidiaries (a “Material Adverse Change”); (ii) transaction that is material to the Enterprise and which is required to be disclosed under the Securities Act, the Exchange Act or the applicable rules and regulations of the Commission; (iii) any obligation, direct or contingent (including any off-balance sheet obligations), incurred by the Company or any Subsidiary, that is material to the Enterprise and which is required to be disclosed under the Securities Act, the Exchange Act or either applicable rules and regulations of the Commission; (iv) material change in the capital stock of the Company or any Subsidiary; (v) material change in the outstanding indebtedness of the Company or any Subsidiary; or (vi) dividend or distribution of any kind declared, paid or made on the capital stock of the Company.

Section 9.     Indemnification.

(a)    Indemnification of the Underwriters by the Company. The Company agrees to indemnify and hold harmless the Underwriters, their officers and employees, and each person, if any, who controls the Underwriters within the meaning of the Securities Act and the Exchange Act against any loss, claim, damage, liability or expense, as incurred, to which the Underwriters or such officer, employee or controlling person may become subject, under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation in accordance with Section 9(d)), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or any amendment thereto, including any Rule 430 Information under the Securities Act, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading; or (ii) any untrue statement or alleged untrue statement of a material fact contained in the Time of Sale Prospectus, any free writing prospectus that the Company has filed, or is required to file, pursuant to Rule 430B or Rule 433(d) of the Securities Act, the Preliminary Prospectus or the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; and to reimburse the Underwriters and each such officer, employee or controlling person for any and all expenses (including the reasonable fees and disbursements of one counsel chosen by the Representative) as such expenses are reasonably incurred by the Underwriters or such officer, employee or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage,

liability, expense or action; provided, however, that the foregoing indemnity agreement in this Section 9(a) shall not apply to any loss, claim, damage, liability or expense to the extent, but only to the extent, arising out of or based upon any untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished to the Company by the Representative expressly for use in the Registration Statement, the Time of Sale Prospectus, any such free writing prospectus, the Preliminary Prospectus or the Prospectus (or any amendment or supplement thereto), it being understood and agreed that the only such information furnished by the Representative to the Company consists of the information described in subsection (b) below. The indemnity agreement set forth in this Section 9(a) shall be in addition to any liabilities that the Company may otherwise have.

(b)    Indemnification of the Company and its Directors and Officers. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, each of its directors and each of its officers who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act, against any loss, claim, damage, liability or expense, as incurred, to which the Company, or any such director, officer, or controlling person, may become subject under the Securities Act, the Exchange Act, or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation in accordance with Section 9(d)), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon any untrue or alleged untrue statement of a material fact contained in (i) the Registration Statement, or any amendment thereto, including any Rule 430 Information or (ii) Time of Sale Prospectus, any free writing prospectus that the Company has filed, or is required to file, pursuant to Rule 430B or Rule 433(d) of the Securities Act, the Preliminary Prospectus or the Prospectus (or any amendment or supplement thereto), or arises out of or is based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, Time of Sale Prospectus, any free writing prospectus that the Company has filed, or is required to file, pursuant to Rule 430B or Rule 433(d) of the Securities Act, the Preliminary Prospectus or the Prospectus (or such amendment or supplement thereto), in reliance upon and in conformity with written information furnished to the Company by the Representative expressly for use therein; and to reimburse the Company, or any such director, officer or controlling person, for any legal and other expense reasonably incurred by the Company, or any such director, officer or controlling person, in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action. The Company hereby acknowledges that the only information that the Representative has furnished to the Company expressly for use in the Registration Statement, Time of Sale Prospectus, any free writing prospectus that the Company has filed, or is required to file, pursuant to Rule 430B or Rule 433(d) of the Securities Act, the Preliminary Prospectus or the Prospectus (or any amendment or supplement thereto) are the statements set forth under the heading “Price Stabilization, Short Positions and Penalty Bids; Passive Market Making” under the caption “Underwriting” in the Prospectus. The indemnity agreement set forth in this Section 9(b) shall be in addition to any liabilities that each Underwriter may otherwise have.

(c)    Notifications and Other Indemnification Procedures.  Promptly after receipt by an indemnified party under this Section 9 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 9, notify the indemnifying party in writing of the commencement thereof, but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party for contribution or otherwise than under the indemnity agreement contained in this Section 9 or to the extent it is not prejudiced as a proximate result of such failure. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party,

the indemnifying party will be entitled to participate in, and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of such indemnifying party’s election so to assume the defense of such action and approval by the indemnified party of such counsel, the indemnifying party will not be liable to such indemnified party under this Section 9 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (together with local counsel), approved by the indemnifying party, representing the indemnified parties who are parties to such action) or (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying party.

(d)    Settlements.  The indemnifying party under this Section 9 shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding.

Section 10.     Contribution. If the indemnification provided for in Section 9 is for any reason held to be unavailable to or otherwise insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount paid or payable by such indemnified party, as incurred, as a result of any losses, claims, damages, liabilities or expenses referred to therein (a) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, from the offering of the Securities pursuant to this Agreement or (b) if the allocation provided by clause (a) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (a) above but also the relative fault of the Company, on the one hand, and the Underwriters, on the other hand, in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company, and the total underwriting discount received by the Underwriters, in each case as set forth on the front cover page of the Prospectus bear to the

aggregate initial public offering price of the Securities as set forth on such cover. The relative fault of the Company, on the one hand, and the Underwriters, 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 relates to information supplied by the Company, on the one hand, or the Underwriters, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Section 9(c), any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim. The provisions set forth in Section 9(c) with respect to notice of commencement of any action shall apply if a claim for contribution is to be made under this Section 10; provided, however, that no additional notice shall be required with respect to any action for that notice has been given under Section 9(c) for purposes of indemnification.

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 10 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 10.

Notwithstanding the provisions of this Section 10, no Underwriter shall be required to contribute any amount in excess of the underwriting discounts and commissions received by such Underwriter in connection with the Securities underwritten by it and distributed to the public. 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. The Underwriters’ obligations to contribute pursuant to this Section 10 are several, and not joint, in proportion to their respective underwriting commitments as set forth opposite their respective names on Schedule A. For purposes of this Section 10, each officer and employee of an Underwriter and each person, if any, who controls an Underwriter within the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as the Company.

Section 11.     Termination of this Agreement. The Representative, by notice given to the Company, shall have the right to terminate this Agreement at any time prior to the First Closing Date or to terminate the obligations of the Underwriters to purchase the Optional Shares at any time prior to the Option Closing Date, as the case may be, if at any time (a)(i) trading or quotation in any of the Company’s securities shall have been suspended or limited by the Commission or the NASDAQ or (ii) trading in securities generally on the NASDAQ shall have been suspended or limited, or minimum or maximum prices shall have been generally established on the NASDAQ by the Commission or FINRA; (b) a general banking moratorium shall have been declared by any federal or New York authorities; (c) there shall have occurred any outbreak or escalation of national or international hostilities or any crisis or calamity, or any change in the United States or international financial markets, or any substantial change or development involving a prospective substantial change in United States’ or international political, financial or economic conditions, as in the judgment of the Representative, is material and adverse and makes it impracticable to market the Securities in the manner and on the terms described in the Time of Sale Prospectus or to enforce contracts for the sale of securities; or (d) the Company shall have sustained a loss by strike, fire, flood, earthquake, accident or other calamity of such character as in the judgment of the Representative may interfere materially with the conduct of the business and operations of the Company regardless of whether or not such loss shall have been insured. Any termination pursuant to this Section 11 shall be without liability on the part of (i) the

Company to any Underwriter, except that the Company shall be obligated to reimburse the expenses of the Underwriters to the extent provided in Section 5 and Section 8 hereof, (ii) any Underwriter to the Company, or (iii) of any party hereto to any other party except that the provisions of Section 9 and Section 10 shall at all times be effective and shall survive such termination.

Section 12.     Defaulting Underwriter.

(a)    If, on the Closing Date or the Option Closing Date, as the case may be, any Underwriter defaults on its obligation to purchase the Securities that it has agreed to purchase hereunder on such date, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Securities by other persons satisfactory to the Company on the terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such Securities on such terms. If other persons become obligated or agree to purchase the Securities of a defaulting Underwriter, either the non-defaulting Underwriters or the Company may postpone the Closing Date or the Option Closing Date, as the case may be, for up to five full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Underwriters may be necessary in the Registration Statement, the Preliminary Prospectus, the Prospectus and the Time of Sale Prospectus or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Registration Statement, the Preliminary Prospectus, the Prospectus and the Time of Sale Prospectus that effects any such changes. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule A hereto that, pursuant to this Section 12, purchases Securities that a defaulting Underwriter agreed but failed to purchase.

(b)    If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate number of Securities that remain unpurchased on the Closing Date or the Option Closing Date, as the case may be, does not exceed one-eleventh of the aggregate number of Securities to be purchased on such date, then the Company shall have the right to require each non-defaulting Underwriter to purchase the number of Securities that such Underwriter agreed to purchase hereunder on such date plus such Underwriter’s pro rata share (based on the number of Securities that such Underwriter agreed to purchase on such date) of the Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made.

(c)    If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate number of Securities that remain unpurchased on the Closing Date or the Option Closing Date, as the case may be, exceeds one-eleventh of the aggregate amount of Securities to be purchased on such date, or if the Company shall not exercise the right described in paragraph (b) above, then this Agreement or, with respect to any Option Closing Date, the obligation of the Underwriters to purchase Securities on the Option Closing Date shall terminate without liability on the part of the non-defaulting Underwriters. Any termination of this Agreement pursuant to this Section 12 shall be without liability on the part of the Company, except that the Company will continue to be liable for the payment of expenses as set forth in Section 5 hereof and except that the provisions of Section 12 hereof shall not terminate and shall remain in effect.

(d)    Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company or any non-defaulting Underwriter for damages caused by its default.

Section 13.     Representations and Indemnities to Survive Delivery. The respective indemnities, agreements, representations, warranties and other statements of the Company, of its officers and of the Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of the Underwriters or the Company or any of its or their partners, officers or directors or any controlling person, as the case may be, and will survive delivery of and payment for the Securities sold hereunder and any termination of this Agreement.

Section 16.     Partial Unenforceability. The invalidity or unenforceability of any Section, paragraph or provision of this Agreement shall not affect the validity or enforceability of any other Section, paragraph or provision hereof.

Section 18.     Entire Agreement; Execution in Counterpart. This Agreement constitutes the entire agreement of the parties to this Agreement and supersedes all prior written or oral and all contemporaneous oral agreements, understandings and negotiations with respect to the subject matter hereof. This Agreement may be executed in two or more counterparts, each one of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement may not be amended or modified unless in writing by all of the parties hereto, and no condition herein (express or implied) may be waived unless waived in writing by each party whom the condition is meant to benefit. The Section headings herein are for the convenience of the parties only and shall not affect the construction or interpretation of this Agreement.

Section 19.     No Fiduciary Relationship.

Each of the parties hereto further acknowledges that the provisions of Sections 9 and 10 hereto fairly allocate the risks in light of the ability of the parties to investigate the Company, its affairs and its business in order to assure that adequate disclosure has been made in the Registration Statement, the Time of Sale Prospectus, each free writing prospectus, the Preliminary Prospectus and the Prospectus (and any amendments and supplements thereto), as required by the Securities Act and the Exchange Act.

The Company acknowledges and agrees that the Underwriters are acting solely in the capacity of an arm’s length contractual counterparty to the Company with respect to the offering of Securities contemplated hereby (including in connection with determining the terms of the offering) and not as a fiduciary to, or an agent of, the Company or any other person. The Company shall consult with its own advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and the Underwriters shall have no responsibility or liability to the Company with respect thereto.

Because the primary purpose of such counsel’s professional engagement was not to establish or confirm factual matters or financial, accounting or statistical information, and because many determinations involved in the preparation of the Registration Statement, the Prospectus and the Time of Sale Prospectus are of a wholly or partially non-legal character, such counsel is not passing upon and does not assume any responsibility for the accuracy, completeness or fairness of the statements (including (i) the financial statements and notes thereto and schedules included or incorporated by reference therein or omitted therefrom, (ii) the summary reserve report of the independent petroleum engineers included or incorporated by reference therein, or (iii) the other financial, accounting, statistical or reserve engineering data contained or incorporated by reference therein or omitted therefrom, as to which such counsel expresses no view) contained in or incorporated by reference in the Registration Statement, the Prospectus and the Time of Sale Prospectus and such counsel makes no representation that it has 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 its preparation of the Prospectus and the Time of Sale Prospectus, prior to the filing of the Prospectus and the Time of Sale Prospectus, such counsel participated in conferences and telephone conversations with representatives of the Company, representatives of the independent public accountants for the Company, representatives of the independent petroleum engineers of the Company, representatives of the Underwriters and representatives of the Underwriters’ counsel, during which conferences and conversations the contents of the Prospectus and the Time of Sale Prospectus and related matters were discussed, and such counsel reviewed certain corporate records and documents furnished to such counsel by the Company.

Based on such counsel’s participation in such conferences and conversations, such counsel’s review of such records and documents as described above, such counsel’s understanding of the U.S. Federal securities laws and the experience such counsel has gained in its practice thereunder, such counsel advises the Underwriters that no information has come to its attention that causes it to believe that (1) the Registration Statement (except (i) the financial statements and notes thereto and schedules included or incorporated by reference therein or omitted therefrom, (ii) the summary reserve report of the independent petroleum engineers included or incorporated by reference therein, or (iii) the other financial, accounting, statistical or reserve engineering data contained or incorporated by reference therein or omitted therefrom, as to which such counsel expresses no view), at the date of the Underwriting Agreement, 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, (2) the Time of Sale Prospectus (except (i) the financial statements and notes thereto and schedules included or incorporated by reference therein or omitted therefrom, (ii) the summary reserve report of the independent petroleum engineers included or incorporated by reference therein, or (iii) the other financial, accounting, statistical or reserve engineering data contained or incorporated by reference therein or omitted therefrom, as to which such counsel expresses no view), as of the Applicable Time included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading or (3) the Prospectus (except (i) the financial statements and notes thereto and schedules included or incorporated by reference therein or omitted therefrom, (ii) the summary reserve report of the independent petroleum engineers included or incorporated by reference therein, or (iii) the other financial, accounting, statistical or reserve engineering data contained or incorporated by reference therein or omitted therefrom, as to which such counsel expresses no view), at the time the Prospectus Supplement was filed with the Commission and as of the First Closing Date and each Option Closing Date, as applicable, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; it being also understood that such counsel expresses no statement or belief in its opinion with respect to representations and warranties included in the exhibits to the Registration Statement.

Such opinion shall be limited to the law of the States of Texas and New York and the Federal securities law of the United States.

As Representative of the several

Underwriters

Ladies & Gentlemen:

The undersigned is an owner of record or beneficially of certain shares of common stock, par value $.01 per share, of the Company (“Shares”) or securities convertible into or exchangeable or exercisable for Shares. The Company proposes to carry out a public offering of Shares (the “Offering”) for which you will act as the representative of the several underwriters. The undersigned recognizes that the Offering will be of benefit to the undersigned and will benefit the Company. The undersigned acknowledges that you and the other underwriters are relying on the representations and agreements of the undersigned contained in this agreement in carrying out the Offering and in entering into an underwriting arrangement with the Company with respect to the Offering. Capitalized terms used, but not defined, in this agreement shall have the meaning given such terms in the Underwriting Agreement to be entered into between Seaport Global Securities LLC, as representative of the several underwriters named therein (the “Representative”), and the Company (the “Underwriting Agreement”).

In consideration of the foregoing, the undersigned hereby agrees that the undersigned will not, and will cause any spouse or immediate family member of the undersigned or such person living in the undersigned’s household (a “Family Member”) not to, without your prior written consent, which consent may be withheld in your sole discretion), directly or indirectly, sell, offer, contract or grant any option to sell (including without limitation any short sale), pledge, transfer, establish an open “put equivalent position” within the meaning of Rule 16a-1(h) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), enter into a swap or other derivatives transaction that transfers to another, in whole or in part, any economic benefits or risk of ownership of such Shares, or otherwise dispose of any Shares, options or warrants to acquire Shares, or securities exchangeable or exercisable for or convertible into Shares currently or hereafter owned either of record or beneficially (as defined in Rule 13d-3 under the Exchange Act by the undersigned (or such spouse or family member), or publicly announce an intention to do any of the foregoing, for a period commencing on the date hereof and continuing through the close of trading on the date 60 days after the date of the Prospectus (as defined in the Underwriting Agreement relating to the Offering to which the Company is a party) (the “Lock-Up Period”); provided, however, that foregoing restrictions shall not apply to transfers of shares of Common Stock or any security directly or indirectly convertible into or exercisable or exchangeable for shares of Common Stock as a bona fide gift or in connection with estate planning, including but not limited to, dispositions to any trust for the direct or indirect benefit of the undersigned and/or the immediate family of the undersigned and dispositions from any grantor retained annuity trust established for the direct benefit of the undersigned and/or a member of the immediate family of the undersigned, or by will or intestacy.

Notwithstanding the foregoing, if (i) during the last 17 days of the Lock-up Period, the Company issues an earnings release or material news or a material event relating to the Company occurs or (ii) prior to the expiration of the Lock-up Period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the Lock-up Period, then in each case the Lock-up Period will be extended until the expiration of the 18-day period beginning on the date of the issuance of the earnings release or the occurrence of the material news or material event, as applicable, unless you waive, in writing, such extension, except that such extension will not apply if, (i) at the expiration of the Lock-up Period, the Shares are “actively traded securities” (as defined in Securities and Exchange Commission Regulation M) and (ii) the Company meets the applicable requirements of paragraph (a)(1) of Rule 139 under the Securities Act of 1933, as amended, in the manner contemplated by FINRA Rule 2241 of the FINRA Manual.

The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of Shares or securities convertible into or exchangeable or exercisable for Shares held by the undersigned except in compliance with the foregoing restrictions. In furtherance of the forgoing, the Company and its transfer agent are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this agreement.

With respect to the Offering only, the undersigned waives any registration rights relating to registration under the Securities Act of 1933, as amended, of any Shares owned either of record or beneficially by the undersigned, including any rights to receive notice of the Offering.

The undersigned further agrees that, for the Lock-Up Period, the undersigned will not, without the prior written consent of the Representative, make any demand for, or exercise any right with respect to, the registration of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock, or warrants or other rights to purchase Common Stock or any such securities. In addition, the undersigned hereby waives any and all preemptive rights, participation rights, resale rights, rights of first refusal and similar rights that the undersigned may have in connection with the Offering or with any issuance or sale by the Company of any equity or other securities before the Offering, except for any such rights as have been heretofore duly exercised.

It is understood that, if the Underwriting Agreement does not become effective, or if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Shares, the undersigned shall be automatically released from all obligations under this agreement.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this agreement and that, upon request, the undersigned will execute any additional documents necessary in connection with the enforcement hereof.

This agreement is irrevocable and will be binding on the undersigned and the respective successors, heirs, personal representatives, and assigns of the undersigned. This agreement shall be governed by and construed in accordance with the internal laws of the State of New York applicable to agreements made and to be performed in such state.

The undersigned acknowledges and agrees that whether or not any Offering actually occurs depends on a number of factors, including market conditions. Any Offering will only be made pursuant to the Underwriting Agreement.
