The Company also proposes to issue and sell to the several Underwriters not more than an additional 3,600,000 shares of its common stock, par value $0.001 per share, (the “Additional Shares”) if and to the extent that you, as managers of the offering, shall have determined to exercise the right to purchase such shares of common stock granted to the Underwriters in Section 2 hereof. The Firm Shares and the Additional Shares are

The Company has filed with the Securities and Exchange Commission (the “Commission”) a registration statement (File No. 333-158554), including a prospectus, on Form S-3, relating to the securities (the “Shelf Securities”), including the Shares, to be issued from time to time by the Company. Such registration statement as amended to the date of this Agreement, including the information (if any) deemed to be part of the registration statement at the time of effectiveness pursuant to Rule 430A or Rule 430 B under the Securities Act of 1933, as amended (the “Securities Act”), is hereinafter referred to as the “Company Registration Statement”, and the related prospectus covering the Shelf Securities dated April 13, 2009 in the form first used to confirm sales of the Shares (or in the form first made available to the Underwriters by the Company to meet requests of purchasers pursuant to Rule 173 under the Securities Act) is hereinafter referred to as the “Company Basic Prospectus.”

The Company has also filed with the Commission a registration statement (File No. 333-158556), including a prospectus, on Form S-3, relating to 47,776,451 shares of common stock, par value $0.001 per share (the “Secondary Shares”), of the Company, which may be offered for sale by the selling shareholders named in such prospectus. Such registration statement as amended to the date of this Agreement, including the information (if any) deemed to be part of the registration statement at the time of effectiveness pursuant to Rule 430A or Rule 430 B under the Securities Act of 1933, as amended (the “Securities Act”), is hereinafter referred to as the “Selling Shareholder Registration Statement” (together with Company Registration Statement, the “Registration Statements”), and the related prospectus covering the Secondary Shares dated April 13, 2009 in the form first used to confirm sales of the Shares (or in the form first made available to the Underwriters by the Company to meet requests of purchasers pursuant to Rule 173 under the Securities Act) is hereinafter referred to as the “Selling Shareholder Basic Prospectus” (together with the Company Basic Prospectus, the “Basic Prospectus”).

1. Representations, Warranties and Agreements of the Company and the Selling Shareholder.

A. The Company represents, warrants and agrees that:

(a) No Stop Order; Automatic Shelf Registration Statements. Each Registration Statement has become effective; no stop order suspending the effectiveness of either Registration Statement is in effect, and no proceedings for such purpose are pending before or threatened by the Commission. Each Registration Statement is an automatic shelf registration statement as defined in Rule 405 under the Securities Act. The Company is a well-known seasoned issuer (as defined in Rule 405 under the Securities Act) eligible to use each Registration Statement as an automatic shelf registration statement and the Company has not received notice that the Commission objects to the use of either Registration Statement as an automatic shelf registration statement.

(b) Company Not Ineligible Issuer. The Company was not at the time of initial filing of each Registration Statement and at the earliest time thereafter that the Company or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2) of the Rules and Regulations) of the Shares, is not on the date hereof and will not be on the applicable Delivery Date an “ineligible issuer” (as defined in Rule 405).

(c) Compliance with Registration Requirements. The Registration Statements conformed and will conform in all material respects on the Effective Date and on the applicable Delivery Date, and any amendment to the Registration Statements filed after the date hereof will conform in all material respects when filed, to the requirements of the Securities Act and the Rules and Regulations. The most recent Preliminary Prospectus conformed, and the Prospectus will conform, in all material respects when filed with the Commission pursuant to Rule 424(b) and on the applicable Delivery Date to the requirements of the Securities Act and the Rules and Regulations.

(d) The Registration Statements. The Registration Statements did not, as of the Effective Date, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; provided that no representation or warranty is made as to information contained in or omitted from the Registration Statements in reliance upon and in conformity with written information furnished to the Company through the Representatives by or on behalf of any Underwriter specifically for inclusion therein, which information is specified in Section 8(f).

(e) The Prospectus. The Prospectus will not, as of its date and on the applicable Delivery Date, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in

the light of the circumstances under which they were made, not misleading; provided that no representation or warranty is made as to information contained in or omitted from the Prospectus in reliance upon and in conformity with written information furnished to the Company through the Representatives by or on behalf of any Underwriter specifically for inclusion therein, which information is specified in Section 8(f).

(f) The Pricing Disclosure Package. As of the Applicable Time, the Pricing Disclosure Package did not contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The preceding sentence does not apply to statements or omissions from the Pricing Disclosure Package based upon and in conformity with written information furnished to the Company by or on behalf of the Underwriters specifically for the inclusion therein, which information is specified in Section 8(f).

(g) Issuer Free Writing Prospectuses. Each Issuer Free Writing Prospectus (including, without limitation, any road show that is a free writing prospectus under Rule 433), when considered together with the Pricing Disclosure Package as of the Applicable Time, did not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

Each Issuer Free Writing Prospectus conformed or will conform in all material respects to the requirements of the Securities Act and the Rules and Regulations on the date of first use, and the Company has complied with all prospectus delivery and any filing requirements applicable to such Issuer Free Writing Prospectus pursuant to the Rules and Regulations. The Company has not made any offer relating to the Shares that would constitute an Issuer Free Writing Prospectus without the prior written consent of the Representatives. The Company has retained in accordance with the Rules and Regulations all Issuer Free Writing Prospectuses that were not required to be filed pursuant to the Rules and Regulations. The Company has taken all actions necessary so that any “road show” (as defined in Rule 433 of the Rules and Regulations) in connection with the offering of the Shares will not be required to be filed pursuant to the Rules and Regulations.

(h) No Integration. None of the Company or any of its subsidiaries has, directly or through any agent, sold, offered for sale, solicited offers to buy or otherwise negotiated in respect of, any “security” (as defined in the Securities Act) that is or will be integrated with the sale of the Shares in a manner that would require registration of such offer or sale of such securities under the Securities Act.

(i) Exclusive Agreement. The Company has not paid or agreed to pay to any person any compensation for soliciting another person to purchase any securities of the Company (except as contemplated in this Agreement).

(j) Statements in Prospectus. The statements in the Prospectus under the headings “Description of Capital Stock” and “Certain U.S. Tax Consequences to Non-U.S.

Each such Company Additional Written Communication, when taken together with the Pricing Disclosure Package, did not, and at the Closing Date will not, contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided that this representation, warranty and agreement shall not apply to statements in or omissions from each such Company Additional Written Communication made in reliance upon and in conformity with information furnished to the Company in writing by the Underwriter expressly for use in any Company Additional Written Communication.

(b) The Selling Shareholder shall indemnify and hold harmless each Underwriter, its directors, officers and employees and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of Shares), to which that Underwriter, director, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in (A) any Preliminary Prospectus, either Registration Statement, the Prospectus or in any amendment or supplement thereto, (B) any Issuer Free Writing Prospectus or in any amendment or supplement thereto or (C) any Permitted Issuer Information used or referred to in any “free writing prospectus” (as defined in Rule 405) used or referred to by any Underwriter, (D) any Non-Prospectus Road Show or (E) any Blue Sky Application or (ii) the omission

or alleged omission to state in any Preliminary Prospectus, either Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Permitted Issuer Information, any Non-Prospectus Road Show or any Blue Sky Application, any material fact required to be stated therein or necessary to make the statements therein not misleading, and shall reimburse each Underwriter and each such director, officer, employee or controlling person promptly upon demand for any legal or other expenses reasonably incurred by that Underwriter, director, officer, employee or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that such Selling Shareholder shall only be subject to such liability to the extent that the untrue statement or alleged untrue statement or omission or alleged omission is based upon information provided by such Selling Shareholder relating to such Selling Shareholder specifically for use therein or contained in a representation or warranty given by such Selling Shareholder in this Agreement, it being understood and agreed that the only such information furnished by any Selling Shareholder consists solely of the Selling Shareholder’s name, number of shares of the Company’s Common Stock held by the Selling Shareholder before and after the Offering and plan to sell its Firm Shares pursuant to this Agreement; provided, further, that, in the event (i) an Indemnified Person shall obtain a final non-appealable judicial judgment, order or decree against the Company for amounts payable by the Company to such Indemnified Person pursuant to this Section 8 which judgment has been and remains unstayed, unsatisfied and undischarged for a period of 90 days or more or (ii) a final, non-appealable judicial judgment, order or decree shall be entered against any Indemnified Person with respect to which such Indemnified Person is entitled to indemnity by or contribution from the Company pursuant to this Section 8 or such Indemnified Person shall have entered into any settlement agreement with respect to any action or proceeding for which such Indemnified Person is entitled to indemnity by or contribution from the Company pursuant to this Section 8 and such Indemnified Person shall have made a demand upon the Company to satisfy the obligations with respect to such judgment or settlement, as the case may be, which demand remains unsatisfied for a period of 90 days or more, then the foregoing provision shall not apply; provided, further, that, in all cases, the liability under this subsection of the Selling Shareholder shall be limited to an amount equal to the aggregate net proceeds (before expenses) to the Selling Shareholder from the sale of Firm Shares sold by the Selling Shareholder hereunder.

(c) Each Underwriter, severally and not jointly, shall indemnify and hold harmless the Company, its directors, officers and employees, the Selling Shareholder and each person, if any, who controls the Company or the Selling Shareholder within the meaning of Section 15 of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Company or any such director, officer, employee, the Selling Shareholder or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, either Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Non-Prospectus Road Show or Blue Sky Application, or (ii) the omission or alleged omission to state in any Preliminary

Prospectus, either Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Non-Prospectus Road Show or Blue Sky Application, any material fact required to be stated therein or necessary to make the statements therein not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information concerning such Underwriter furnished to the Company through the Representatives by or on behalf of that Underwriter specifically for inclusion therein, which information is limited to the information set forth in Section 8(f). The foregoing indemnity agreement is in addition to any liability that any Underwriter may otherwise have to the Company or any such director, officer, employee or controlling person.

(d) Promptly after receipt by an indemnified party under this Section 8 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 8. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 8 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the indemnified party shall have the right to employ counsel to represent jointly the indemnified party and those other indemnified parties and their respective directors, officers, employees and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought under this Section 8 if (i) the indemnified party and the indemnifying party shall have so mutually agreed; (ii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party; (iii) the indemnified party and its directors, officers, employees and controlling persons shall have reasonably concluded that there may be legal defenses available to them that are different from or in addition to those available to the indemnifying party; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the indemnified parties or their respective directors, officers, employees or controlling persons, on the one hand, and the indemnifying party, on the other hand, and representation of both sets of parties by the same counsel would be inappropriate due to actual or potential differing interests between them, and in any such event the fees and expenses of such separate counsel shall be paid by the indemnifying party. No indemnifying party shall (x) without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or

consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and does not include any findings of fact or admissions of fault or culpability or a failure to act as to the indemnified party, or (y) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment for the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment.

(e) If the indemnification provided for in this Section 8 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 8(a), 8(b) or 8(c) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party (which for purposes of this Section 8(e) does not include the Selling Shareholder, whose obligations for contribution shall be governed by Section 8(b)) shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriters, on the other, from the offering of the Shares or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company, on the one hand, and the Underwriters, on the other, with respect to the statements or omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, 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, with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Shares purchased under this Agreement (before deducting expenses) received by the Company, as set forth in the table on the cover page of the Prospectus, on the one hand, and the total underwriting discounts and commissions received by the Underwriters with respect to the shares of the Shares purchased under this Agreement, as set forth in the table on the cover page of the Prospectus, on the other hand. The relative fault shall be determined by reference to whether the 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 or the Underwriters, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 8(e) were to be determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 8(e) shall be deemed to include, for purposes of this Section 8(e), 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 Section 8(e), no Underwriter shall be required to contribute any amount in excess of the amount by which the net proceeds from the sale of the Shares underwritten by it exceeds the amount of any damages that such Underwriter

has otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute as provided in this Section 8(e) are several in proportion to their respective underwriting obligations and not joint.

(f) The Underwriters severally confirm and the Company and the Selling Shareholder each acknowledges and agrees that the statements set forth in the second paragraph under the caption “Underwriting—Commission and Expenses” and the first and second paragraphs under the caption “Underwriting—Stabilization, Short Positions and Penalty Bids” in the most recent Preliminary Prospectus and the Prospectus are correct and constitute the only information concerning such Underwriters furnished in writing to the Company by or on behalf of the Underwriters specifically for inclusion in any Preliminary Prospectus, either Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Non-Prospectus Road Show.

9. Defaulting Underwriters. If, on any Delivery Date, any Underwriter defaults in the performance of its obligations under this Agreement, the remaining non-defaulting Underwriters shall be obligated to purchase the Shares that the defaulting Underwriter agreed but failed to purchase on such Delivery Date in the respective proportions which the number of shares of the Firm Shares set forth opposite the name of each remaining non-defaulting Underwriter in Schedule 1 hereto bears to the total number of shares of the Firm Shares set forth opposite the names of all the remaining non-defaulting Underwriters in Schedule 1 hereto; provided, however, that the remaining non-defaulting Underwriters shall not be obligated to purchase any of the Shares on such Delivery Date if the total number of shares of the Shares that the defaulting Underwriter or Underwriters agreed but failed to purchase on such date exceeds 9.09% of the total number of shares of the Shares to be purchased on such Delivery Date, and any remaining non-defaulting Underwriter shall not be obligated to purchase more than 110% of the number of shares of the Shares that it agreed to purchase on such Delivery Date pursuant to the terms of Section 2. If the foregoing maximums are exceeded, the remaining non-defaulting Underwriters, or those other underwriters satisfactory to the Representatives who so agree, shall have the right, but shall not be obligated, to purchase, in such proportion as may be agreed upon among them, all the Shares to be purchased on such Delivery Date. If the remaining Underwriters or other underwriters satisfactory to the Representatives do not elect to purchase the shares that the defaulting Underwriter or Underwriters agreed but failed to purchase on such Delivery Date, this Agreement (or, with respect to any Additional Shares Delivery Date, the obligation of the Underwriters to purchase, and of the Company to sell, the Additional Shares) shall terminate without liability on the part of any non-defaulting Underwriter or the Company, except that the Company will continue to be liable for the payment of expenses to the extent set forth in Sections 6 and 11. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context requires otherwise, any party not listed in Schedule 1 hereto that, pursuant to this Section 9, purchases Shares that a defaulting Underwriter agreed but failed to purchase. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 9, purchases shares that a defaulting Underwriter agreed but failed to purchase.

Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company for damages caused by its default. If other Underwriters are obligated or agree to purchase the Shares of a defaulting or withdrawing Underwriter, either the Representatives or the Company may postpone the Delivery Date for up to seven 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 Prospectus or in any other document or arrangement.

10. Termination. On or after the Applicable Time, this Agreement may be terminated by the Representatives by notice given to the Company if at any time (i) trading in securities generally on either the New York Stock Exchange shall have been suspended or materially limited, or minimum or maximum prices shall have been generally established on any of such stock exchanges by the Commission or the FINRA; (ii) a general banking moratorium shall have been declared by any federal or New York authority or a material disruption in commercial banking or securities settlement or clearance services in the United States has occurred; or (iii) there shall have occurred any outbreak or escalation of national or international hostilities or any crisis or calamity, or any change in the United States or international financial markets, or any substantial change or development involving a prospective substantial change in United States’ or international political, financial or economic conditions, as in the judgment of the Representatives is material and adverse and makes it impracticable or inadvisable to market the Shares in the manner and on the terms described in the Disclosure Package or the Final Prospectus or to enforce contracts for the sale of securities.

11. Reimbursement of Underwriters’ Expenses. If the Company shall fail to tender the Shares for delivery to the Underwriters for any reason or (b) the Underwriters shall decline to purchase the Shares for any reason permitted under this Agreement (other than Section 9 or Section 10), the Company will reimburse the Underwriters for all reasonable out-of-pocket expenses (including fees and disbursements of counsel) incurred by the Underwriters in connection with this Agreement and the proposed purchase of the Shares, and upon demand the Company shall pay the full amount thereof to the Representatives. If this Agreement is terminated pursuant to Section 9 by reason of the default of one or more Underwriters, the Company shall not be obligated to reimburse any defaulting Underwriter on account of those expenses.

12. Research Analyst Independence. The Company acknowledges that the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriters’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Company and/or the offering that differ from the views of their respective investment banking divisions. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the

Company by such Underwriters’ investment banking divisions. The Company acknowledges that each of the Underwriters is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the companies that may be the subject of the transactions contemplated by this Agreement.

13. No Fiduciary Duty. The Company acknowledges and agrees that in connection with this offering, sale of the Shares or any other services the Underwriters may be deemed to be providing hereunder, notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Underwriters: (i) no fiduciary or agency relationship between the Company and any other person, on the one hand, and the Underwriters, on the other, exists; (ii) the Underwriters are not acting as advisors, expert or otherwise, to the Company, including, without limitation, with respect to the determination of the public offering price of the Shares, and such relationship between the Company, on the one hand, and the Underwriters, on the other, is entirely and solely commercial, based on arms-length negotiations; (iii) any duties and obligations that the Underwriters may have to the Company shall be limited to those duties and obligations specifically stated herein; and (iv) the Underwriters and their respective affiliates may have interests that differ from those of the Company. The Company hereby waives any claims that the Company may have against the Underwriters with respect to any breach of fiduciary duty in connection with this offering.

14. Notices, etc. All statements, requests, notices and agreements hereunder shall be in writing, and:

Ladies and Gentlemen:

The undersigned understands that you and certain other firms (the “Underwriters”) propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) providing for the purchase by the Underwriters of shares (the “Shares”) of Common Stock, par value $0.001 per share (the “Common Stock”), of SandRidge Energy, Inc., a Delaware corporation (the “Company”), and that the Underwriters propose to reoffer the Shares to the public (the “Offering”).

In consideration of the execution of the Underwriting Agreement by the Underwriters, and for other good and valuable consideration, the undersigned hereby irrevocably agrees that, without the prior written consent of Barclays Capital Inc., on behalf of the Underwriters, the undersigned will not, directly or indirectly, (1) offer for sale, sell, pledge, or otherwise dispose of (or enter into any transaction or device that is designed to, or could be expected to, result in the disposition by any person at any time in the future of) any shares of Common Stock (including, without limitation, shares of Common Stock that may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and shares of Common Stock that may be issued upon exercise of any options or

In furtherance of the foregoing, 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 Lock-Up Letter Agreement.

It is understood that, if the Company notifies the Underwriters that it does not intend to proceed with the Offering, if the Underwriting Agreement does not become effective, if the Offering shall not have commenced by December 4, 2009, 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 will be released from its obligations under this Lock-Up Letter Agreement.

The undersigned understands that the Company and the Underwriters will proceed with the Offering in reliance on this Lock-Up Letter Agreement.

Whether or not the Offering actually occurs depends on a number of factors, including market conditions. Any Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation between the Company and the Underwriters.

(ii) The authorized capital stock of the Company is as set forth under the caption “Capitalization” in the Final Prospectus; and the authorized capital stock of the Company conforms in all material respects as to legal matters to the description thereof contained in the Final Prospectus under the caption “Description of Capital Stock.”

In addition, such counsel shall state that, as counsel to the Company, they reviewed the Registration Statements, the Disclosure Package and the Final Prospectus and participated in discussions with representatives of the Underwriters and those of the Company, counsel to the Underwriters and the Company’s accountants. On the basis of the information which was reviewed by them in the course of the performance of the services referred to above, considered in the light of such counsel’s understanding of the applicable law and the experience such counsel has gained through their practice under the Federal securities laws, such counsel shall confirm that nothing which came to their attention in the course of such review has caused such counsel to believe that:

except that in each case such counsel need not assume responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statements, the Disclosure Package or the Final Prospectus, except as specified in Paragraph (vii) above. Also, such counsel need not express any opinion or belief as to the financial statements, including the notes thereto, and the financial statement schedules and other financial data and the oil and gas reserve and production data included in the Registration Statements, the Disclosure Package or the Final Prospectus.
