Ladies and Gentlemen:

Introductory. SM Energy Company, a Delaware corporation (the “Company”), proposes to issue and sell to the several Initial Purchasers named in Schedule A (the “Initial Purchasers”), acting severally and not jointly, the respective amounts set forth in such Schedule A of $350,000,000 aggregate principal amount of the Company’s 6⅝% Senior Notes due 2019 (the “Securities”).  Xxxxxxx Lynch, Pierce, Xxxxxx & Xxxxx Incorporated (“Xxxxxxx Xxxxx”) and Xxxxx Fargo Securities, LLC have agreed to act as the representatives of the several Initial Purchasers (the “Representatives”) in connection with the offering and sale of the Securities.

The Securities will be issued pursuant to an indenture, to be dated as of February 7, 2011 (the “Indenture”), between the Company and U.S. Bank National Association, as trustee (the “Trustee”).  The Securities will be issued only in book-entry form in the name of Cede & Co., as nominee of The Depository Trust Company (the “Depositary”), pursuant to a letter of representations, to be dated on or before the Closing Date (as defined in Section 2 hereof) (the “DTC Agreement”), between the Company and the Depositary.

The holders of the Securities will be entitled to the benefits of a registration rights agreement, to be dated as of February 7, 2011 (the “Registration Rights Agreement”), among the Company and the Initial Purchasers, pursuant to which the Company will be required to file with the Commission (as defined below), under the circumstances set forth therein, (i) a registration statement under the Securities Act (as defined below) relating to another series of debt securities of the Company with terms substantially identical to the Securities (the “Exchange Securities”) to be offered in exchange for the Securities (the “Exchange Offer”); and (ii) a shelf registration statement pursuant to Rule 415 of the Securities Act relating to the resale by certain holders of the Securities, and in each case, to use its best efforts to cause such registration statements to be declared effective.  All references herein to the Exchange Securities and the Exchange Offer are applicable only if the Company is in fact required to consummate the Exchange Offer pursuant to the terms of the Registration Rights Agreement.

This Agreement, the Registration Rights Agreement, the Securities, the Exchange Securities and the Indenture are referred to herein as the “Transaction Documents.”

The Company understands that the Initial Purchasers propose to make an offering of the Securities on the terms and in the manner set forth herein and in the Pricing Disclosure Package (as defined below) and agrees that the Initial Purchasers may resell, subject to the conditions set forth herein, all or a portion of the Securities to purchasers (the “Subsequent Purchasers”) on the terms set forth in the Pricing Disclosure Package (the first time when sales of the Securities are made is referred to as the “Time of Sale”).  The Securities are to be offered and sold to or through the Initial Purchasers without being registered with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933 (as amended, the “Securities Act,” which term, as used herein, includes the rules and regulations of the Commission promulgated thereunder), in reliance upon exemptions therefrom.  Pursuant to the terms of the Securities and the Indenture, investors who acquire Securities shall be deemed to have agreed that Securities may only be resold or otherwise transferred, after the date hereof, if such Securities are registered for sale under the Securities Act or if an exemption from the registration requirements of the Securities Act is available (including the exemptions afforded by Rule 144A under the Securities Act (“Rule 144A”) or Regulation S under the Securities Act (“Regulation S”)).

The Company has prepared and delivered to each Initial Purchaser copies of a Preliminary Offering Memorandum, dated January 25, 2011 (the “Preliminary Offering Memorandum”), and has prepared and delivered to each Initial Purchaser copies of a Pricing Supplement, dated January 31, 2011 (the “Pricing Supplement”) and included in Annex I to this Agreement, describing the terms of the Securities, each for use by such Initial Purchaser in connection with its solicitation of offers to purchase the Securities.  The Preliminary Offering Memorandum and the Pricing Supplement are herein referred to as the “Pricing Disclosure Package.”  Promptly after this Agreement is executed and delivered, the Company will prepare and deliver to each Initial Purchaser a final offering memorandum dated the date hereof (the “Final Offering Memorandum”).

All references herein to the terms “Pricing Disclosure Package” and “Final Offering Memorandum” shall be deemed to mean and include all information filed under the Securities Exchange Act of 1934 (as amended, the “Exchange Act,” which term, as used herein, includes the rules and regulations of the Commission promulgated thereunder) prior to the Time of Sale and incorporated by reference in the Pricing Disclosure Package (including the Preliminary Offering Memorandum) or the Final Offering Memorandum (as the case may be), and all references herein to the terms “amend,” “amendment” or “supplement” with respect to the Final Offering Memorandum shall be deemed to mean and include all information filed under the Exchange Act after the Time of Sale and incorporated by reference in the Final Offering Memorandum.

As used herein, a “Repayment Event” means any event or condition which gives the holder of any note, debenture or other evidence of indebtedness (or any person acting on such holder’s behalf) the right to require the repurchase, redemption or repayment of all or a portion of such indebtedness by the Company.

(t) Absence of Proceedings. There is no action, suit, proceeding, inquiry or investigation before or brought by any court or governmental agency or body, domestic or foreign, now pending, or, to the knowledge of the Company, threatened, against or affecting the Company or any of its subsidiaries which is required to be disclosed in the Offering Memorandum (other than as disclosed therein), or which might reasonably be expected to result in a Material Adverse Change, or which might reasonably be expected to materially and adversely affect the properties or assets of the Company or any of its subsidiaries or the consummation of the transactions contemplated by this Agreement or the performance by the Company of its obligations hereunder.

No filing with, or authorization, approval, consent, license, order, registration, qualification or decree of, any court or governmental authority or agency is necessary or required for the performance by the Company of its obligations under the Transaction Documents, in connection with the offering, issuance or sale of the Securities hereunder or the consummation of the transactions contemplated by the Transaction Documents or for the due execution, delivery or performance of the Transaction Documents by the Company, except (i) such as have been already obtained; (ii) as may be required under the Securities Act in connection with the transactions contemplated by the Registration Rights Agreement or state securities laws and (iii) for the qualification of the Indenture under the Trust Indenture Act.

(cc) Accounting Controls and Disclosure Controls. The Company and each of its subsidiaries maintain a system of internal accounting 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 the existing assets at reasonable intervals and appropriate action is taken with respect to any differences.

The Company 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 result in a Material Adverse Change.

(gg) No Price Stabilization or Manipulation.  The Company has not taken and will not take, directly or indirectly, any action designed to or that might be reasonably expected to cause or result in stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities.

(ii) Regulations T, U, X.  Neither the Company nor any of its subsidiaries nor any agent thereof acting on their behalf has taken, and none of them will take, any action that might cause this Agreement or the issuance or sale of the Securities to violate Regulation T, Regulation U or Regulation X of the Board of Governors of the Federal Reserve System.

(jj) ERISA Compliance.  Except as otherwise disclosed in the Offering Memorandum, the Company and its subsidiaries and any “employee benefit plan” (as defined in Section 3(3) of the Employee Retirement Income Security Act of 1974 (as amended, “ERISA,” which term, as used herein, includes the regulations and published interpretations thereunder) established or maintained by the Company, its subsidiaries or their ERISA Affiliates (as defined below) are in compliance in all material respects with ERISA and, to the knowledge of the Company, each “multiemployer plan” (as defined in Section 4001 of ERISA) to which the Company, its subsidiaries or an ERISA Affiliate contributes (a “Multiemployer Plan”) is in compliance in all material respects with ERISA.  “ERISA Affiliate” means, with respect to the Company or a subsidiary, any member of any group of organizations described in Section 414(b), (c), (m) or (o) of the Internal Revenue Code of 1986 (as amended, the “Code,” which term, as used herein, includes the regulations and published interpretations thereunder) of which the Company or such subsidiary is or, within the last six years, has been a member.  No “reportable event” (as defined in Section 4043 of ERISA) has occurred or is reasonably expected to occur with respect to any “employee benefit plan” established or maintained by the Company, its subsidiaries or any of their ERISA Affiliates.  No “single employer plan” (as defined in Section 4001 of ERISA) established or maintained by the Company, its subsidiaries or any of their ERISA Affiliates, if such “employee benefit plan” were terminated, would have any “amount of unfunded benefit liabilities” (as defined in Section 4001 of ERISA) that would, singly or in the aggregate (with any other such “single employer plan”), reasonably be expected to result in a Material Adverse Change.  Neither the Company, its subsidiaries nor any of their ERISA Affiliates has incurred or reasonably expects to incur any liability (i) under Title IV of ERISA with respect to termination of, or withdrawal from, any “employee benefit plan” or (ii) that would, singly or in the aggregate, reasonably be expected to result in a Material Adverse Change under Sections 430, 4971, 4975 or 4980B of the Code.  To the knowledge of the Company, each “employee benefit plan” established or maintained by the Company, its subsidiaries or any of their ERISA Affiliates that is intended to be qualified under Section 401 of the Code is so qualified and nothing has occurred, whether by action or failure to act, which would cause the loss of such qualification.

(kk) Compliance with Labor Laws.  Except as otherwise disclosed in the Offering Memorandum or as would not, individually or in the aggregate, result in a Material Adverse Change, (i) there is (A) no unfair labor practice complaint pending or, to the best of the Company’s knowledge, threatened against the Company or any of its subsidiaries before the National Labor Relations Board, and no grievance or arbitration proceeding arising out of or under collective bargaining agreements pending, or to the best of the Company’s knowledge, threatened, against the Company or any of its subsidiaries, (B) no strike, labor dispute, slowdown or stoppage pending or, to the best of the Company’s knowledge, threatened against the Company or any of its subsidiaries and (C) no union representation question existing with respect to the employees of the Company or any of its subsidiaries and, to the best of the Company’s knowledge, no union organizing activities taking place and (ii) there has been no violation of any federal, state or local law relating to discrimination in hiring, promotion or pay of employees or of any applicable wage or hour laws.

(mm) Foreign Corrupt Practices Act. Neither the Company nor, to the knowledge of the Company, any director, officer, agent, employee, Affiliate or other person acting on behalf of the Company or any of its subsidiaries is aware of or has taken any action, directly or indirectly, that would result in a violation by such persons of the Foreign Corrupt Practices Act of 1977, as amended, and the rules and regulations thereunder (the “FCPA”), including, without limitation, making use of the mails or any means or instrumentality of interstate commerce corruptly in furtherance of an offer, payment, promise to pay or authorization of the payment of any money, or other property, gift, promise to give, or authorization of the giving of anything of value to any “foreign official” (as such term is defined in the FCPA) or any foreign political party or official thereof or any candidate for foreign political office, in contravention of the FCPA and the Company and, to the knowledge of the Company, its Affiliates have conducted their businesses in compliance with the FCPA and have instituted and maintain policies and procedures designed to ensure, and which are reasonably expected to continue to ensure, continued compliance therewith.

(nn) Money Laundering Laws. The operations of the Company are and have been conducted at all times materially in compliance with applicable financial recordkeeping and reporting requirements of the Currency and Foreign Transactions Reporting Act of 1970, as amended, the money laundering statutes of all applicable jurisdictions, the rules and regulations thereunder and any related or similar rules, regulations or guidelines, issued, administered or enforced by any governmental agency (collectively, the “Money Laundering Laws”) and no action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving the Company or any of its subsidiaries with respect to the Money Laundering Laws is pending or, to the best knowledge of the Company, threatened.

(oo) No Conflict with OFAC Laws. Neither the Company nor any of its subsidiaries nor, to the knowledge of the Company, any director, officer, agent, employee or Affiliate of the Company or any of its subsidiaries is currently subject to any U.S. sanctions administered by the Office of Foreign Assets Control of the U.S. Treasury Department (“OFAC”); and the Company 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 or entity, for the purpose of financing the activities of any person currently subject to any U.S. sanctions administered by OFAC.

(pp) Forward-Looking Statements.  No forward-looking statement (within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act) contained in the Offering Memorandum has been made or reaffirmed without a reasonable basis or has been disclosed other than in good faith.

(qq) Regulation S.  The Company and its affiliates and all persons acting on their behalf (other than the Initial Purchasers, as to whom the Company makes no representation) have complied with and will comply with the offering restrictions requirements of Regulation S in connection with the offering of the Securities outside the United States and, in connection therewith, the Offering Memorandum will contain the disclosure required by Rule 902.  The Company is a “reporting issuer,” as defined in Rule 902 under the Securities Act.

Any certificate signed by any officer of the Company or any of its subsidiaries and delivered to the Representatives or to counsel for the Initial Purchasers shall be deemed to be a representation and warranty by the Company to each Initial Purchaser as to the matters covered thereby.

(b) Amendments and Supplements to the Final Offering Memorandum and Other Securities Act Matters.  If at any time prior to the Closing Date (i) any event shall occur or condition shall exist as a result of which any of the Pricing Disclosure Package as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading or (ii) it is necessary to amend or supplement any of the Pricing Disclosure Package to comply with law, the Company will immediately notify the Initial Purchasers thereof and forthwith prepare and (subject to Section 3(a) hereof) furnish to the Initial Purchasers such amendments or supplements to any of the Pricing Disclosure Package (including any information filed under the Exchange Act and incorporated by reference therein) as may be necessary so that the statements in any of the Pricing Disclosure Package as so amended or supplemented (including such information filed under the Exchange Act and incorporated by reference therein) will not, in the light of the circumstances under which they were made, be misleading or so that any of the Pricing Disclosure Package will comply with all applicable law.  If, prior to the completion of the placement of the Securities by the Initial Purchasers with the Subsequent Purchasers, any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Final Offering Memorandum, as then amended or supplemented, in order to make the statements therein, in the light of the circumstances when the Final Offering Memorandum is delivered to a Subsequent Purchaser, not misleading, or if in the judgment of the Representatives or counsel for the Initial Purchasers it is otherwise necessary to amend or supplement the Final Offering Memorandum to comply with law, the Company agrees to promptly prepare (subject to Section 3 hereof), furnish at its own expense to the Initial Purchasers, amendments or supplements to the Final Offering Memorandum so that the statements in the Final Offering Memorandum as so amended or supplemented will not, in the light of the circumstances at the Closing Date and at the time of sale of Securities, be misleading or so that the Final Offering Memorandum, as amended or supplemented, will comply with all applicable law.

(a) Indemnification of the Initial Purchasers.  The Company agrees to indemnify and hold harmless each Initial Purchaser, its affiliates, directors, officers and employees, and each person, if any, who controls any Initial Purchaser within the meaning of the Securities Act and the Exchange Act against any loss, claim, damage, liability or expense, as incurred, to which such Initial Purchaser, affiliate, director, officer, employee or controlling person may become subject, under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the Company), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based:  (i) upon any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Offering Memorandum, the Pricing Supplement, any Company Additional Written Communication or the Final Offering Memorandum (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; (ii) in whole or in part upon any inaccuracy in the representations and warranties of the Company contained herein; (iii) in whole or in part upon any failure of the Company to perform its obligations hereunder or under law; (iv) any act or failure to act or any alleged act or failure to act by any Initial Purchaser in connection with, or relating in any manner to, the offering contemplated hereby, and which is included as part of or referred to in any loss, claim, damage, liability or action arising out of or based upon any matter covered by clause (i) above, provided that the Company shall not be liable under this clause (iv) to the extent that a court of competent jurisdiction shall have determined by a final judgment that such loss, claim, damage, liability or action resulted directly from any such acts or failures to act undertaken or omitted to be taken by such Initial Purchaser through its gross negligence or willful misconduct; and to reimburse each Initial Purchaser and each such affiliate, director, officer, employee or controlling person for any and all expenses (including the fees and disbursements of counsel chosen by Xxxxxxx Xxxxx) as such expenses are reasonably incurred by such Initial Purchaser or such affiliate, director, officer, employee or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the foregoing indemnity agreement shall not apply, with respect to an Initial Purchaser, to any loss, claim, damage, liability or expense to the extent, but only to the extent, arising out of or based upon any untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished to the Company by such Initial Purchaser through the Representatives expressly for use in the Preliminary Offering Memorandum, the Pricing Supplement, any Company Additional Written Communication or the Final Offering Memorandum (or any amendment or supplement thereto).  The indemnity agreement set forth in this Section 8(a) shall be in addition to any liabilities that the Company may otherwise have.

(b) Indemnification of the Company.  Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless the Company and its directors 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 or controlling person may become subject, under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of such Initial Purchaser), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Offering Memorandum, the Pricing Supplement, any Company Additional Written Communication or the Final Offering Memorandum (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Preliminary Offering Memorandum, the Pricing Supplement, any Company Additional Written Communication or the Final Offering Memorandum (or any amendment or supplement thereto), in reliance upon and in conformity with written information furnished to the Company by such Initial Purchaser through the Representatives expressly for use therein; and to reimburse the Company and each such director or controlling person for any and all expenses (including the fees and disbursements of counsel) as such expenses are reasonably incurred by the Company or such director 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 Initial Purchasers through the Representatives have furnished to the Company expressly for use in the Preliminary Offering Memorandum, the Pricing Supplement, any Company Additional Written Communication or the Final Offering Memorandum (or any amendment or supplement thereto) are the statements set forth in the fourth, seventh, eighth and ninth paragraphs under the caption “Plan of Distribution” in the Preliminary Offering Memorandum and the Final Offering Memorandum.  The indemnity agreement set forth in this Section 8(b) shall be in addition to any liabilities that each Initial Purchaser may otherwise have.

(c) Notifications and Other Indemnification Procedures.  Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; provided that the failure to so notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party under this Section 8 except to the extent that it has been materially prejudiced by such failure (through the forfeiture of substantive rights and defenses) and shall not relieve the indemnifying party from any liability that the indemnifying party may have to an indemnified party other than under this Section 8.  In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties.  Upon receipt of notice from the indemnifying party to such indemnified party of such indemnifying party’s election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 8 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the immediately preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (together with local counsel (in each jurisdiction)), which shall be selected by Xxxxxxx Xxxxx in the case of counsel representing the Initial Purchasers or their related persons), representing the indemnified parties who are parties to such action); or (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying party.

(d) Settlements.  The indemnifying party under this Section 8 shall not be liable for any settlement of any proceeding effected without its written consent, which will not be unreasonably withheld, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment.  No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding; and (ii) does not include any statements as to or any findings of fault, culpability or failure to act by or on behalf of any indemnified party.

SECTION 9. Contribution.  If the indemnification provided for in Section 8 hereof is for any reason held to be unavailable to or otherwise insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount paid or payable by such indemnified party, as incurred, as a result of any losses, claims, damages, liabilities or expenses referred to therein (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Initial Purchasers, on the other hand, from the offering of the Securities pursuant to this Agreement; or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company, on the one hand, and the Initial Purchasers, on the other hand, in connection with the statements or omissions or inaccuracies in the representations and warranties herein which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations.  The relative benefits received by the Company, on the one hand, and the Initial Purchasers, on the other hand, in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company, and the total discount received by the Initial Purchasers bear to the aggregate initial offering price of the Securities.  The relative fault of the Company, on the one hand, and the Initial Purchasers, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact or any such inaccurate or alleged inaccurate representation or warranty relates to information supplied by the Company, on the one hand, or the Initial Purchasers, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission or inaccuracy.

The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Section 8 hereof, any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim.  The provisions set forth in Section 8 hereof with respect to notice of commencement of any action shall apply if a claim for contribution is to be made under this Section 9; provided, however, that no additional notice shall be required with respect to any action for which notice has been given under Section 8 hereof for purposes of indemnification.

The Company and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 9 were determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 9.

Notwithstanding the provisions of this Section 9, no Initial Purchaser shall be required to contribute any amount in excess of the discount received by such Initial Purchaser in connection with the Securities distributed by it.  No person guilty of fraudulent misrepresentation (within the meaning of Section 11 of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.  The Initial Purchasers’ obligations to contribute pursuant to this Section 9 are several, and not joint, in proportion to their respective commitments as set forth opposite their names in Schedule A.  For purposes of this Section 9, each director, officer and employee of an Initial Purchaser and each person, if any, who controls an Initial Purchaser within the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as such Initial Purchaser, and each director of the Company, and each person, if any, who controls the Company with the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as the Company.

SECTION 10. Termination of this Agreement.  Prior to the Closing Date, this Agreement may be terminated by the Representatives by notice given to the Company if at any time:  (i) trading or quotation in any of the Company’s securities shall have been suspended or limited by the Commission or by the NYSE; (ii) trading in securities generally on either the Nasdaq Stock Market or the NYSE shall have been suspended or limited, or minimum or maximum prices shall have been generally established on any of such quotation system or stock exchange by the Commission or FINRA; (iii) a general banking moratorium shall have been declared by any federal or New York authorities; (iv) 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 proceed with the offering sale or delivery of the Securities in the manner and on the terms described in the Pricing Disclosure Package or to enforce contracts for the sale of securities; (v) in the judgment of the Representatives there shall have occurred any Material Adverse Change; or (vi) 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 Representatives may interfere materially with the conduct of the business and operations of the Company regardless of whether or not such loss shall have been insured.  Any termination pursuant to this Section 10 shall be without liability on the part of (1) the Company to any Initial Purchaser, except that the Company shall be obligated to reimburse the expenses of the Initial Purchasers pursuant to Sections 4 and 6 hereof; (2) any Initial Purchaser to the Company; or (3) any party hereto to any other party except that the provisions of Sections 8 and 9 hereof shall at all times be effective and shall survive such termination.

SECTION 11. Representations and Indemnities to Survive Delivery.  The respective indemnities, agreements, representations, warranties and other statements of the Company, its directors and the several Initial Purchasers set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Initial Purchaser, the Company, or any of their partners, officers or directors or any controlling person, as the case may be, and will survive delivery of and payment for the Securities sold hereunder and any termination of this Agreement.

SECTION 13. Successors.  This Agreement will inure to the benefit of and be binding upon the parties hereto, and to the benefit of the indemnified parties referred to in Sections 8 and 9 hereof, and in each case their respective successors, and no other person will have any right or obligation hereunder.  The term “successors” shall not include any Subsequent Purchaser or other purchaser of the Securities as such from any of the Initial Purchasers merely by reason of such purchase.

SECTION 14. Authority of the Representatives.  Any action by the Initial Purchasers hereunder may be taken by the Representatives on behalf of the Initial Purchasers, and any such action taken by the Representatives shall be binding upon the Initial Purchasers.

SECTION 15. Partial Unenforceability.  The invalidity or unenforceability of any section, paragraph or provision of this Agreement shall not affect the validity or enforceability of any other section, paragraph or provision hereof.  If any section, paragraph or provision of this Agreement is for any reason determined to be invalid or unenforceable, there shall be deemed to be made such minor changes (and only such minor changes) as are necessary to make it valid and enforceable.

SECTION 16. Governing Law Provisions.  THIS AGREEMENT 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 WITHOUT REGARD TO CONFLICTS OF LAW PRINCIPLES THEREOF.

(a) Consent to Jurisdiction.  Any legal suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby (“Related Proceedings”) may be instituted in the federal courts of the United States of America located in the City and County of New York or the courts of the State of New York in each case located in the City and County of New York (collectively, the “Specified Courts”), and each party irrevocably submits to the exclusive jurisdiction (except for suits, actions, or proceedings instituted in regard to the enforcement of a judgment of any Specified Court in a Related Proceeding, as to which such jurisdiction is non-exclusive) of the Specified Courts in any Related Proceeding.  Service of any process, summons, notice or document by mail to such party’s address set forth above shall be effective service of process for any Related Proceeding brought in any Specified Court.  The parties irrevocably and unconditionally waive any objection to the laying of venue of any Specified Proceeding in the Specified Courts and irrevocably and unconditionally waive and agree not to plead or claim in any Specified Court that any Related Proceeding brought in any Specified Court has been brought in an inconvenient forum.

SECTION 17. Default of One or More of the Several Initial Purchasers.  If any one or more of the several Initial Purchasers shall fail or refuse to purchase Securities that it or they have agreed to purchase hereunder on the Closing Date, and the aggregate number of Securities which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase does not exceed 10% of the aggregate number of the Securities to be purchased on such date, the other Initial Purchasers shall be obligated, severally, in the proportions that the number of Securities set forth opposite their respective names on Schedule A bears to the aggregate number of Securities set forth opposite the names of all such non-defaulting Initial Purchasers, or in such other proportions as may be specified by the Initial Purchasers with the consent of the non-defaulting Initial Purchasers, to purchase the Securities which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase on the Closing Date.  If any one or more of the Initial Purchasers shall fail or refuse to purchase Securities and the aggregate number of Securities with respect to which such default occurs exceeds 10% of the aggregate number of Securities to be purchased on the Closing Date, and arrangements satisfactory to the Initial Purchasers and the Company for the purchase of such Securities are not made within 48 hours after such default, this Agreement shall terminate without liability of any party to any other party except that the provisions of Sections 4, 6, 8 and 9 hereof shall at all times be effective and shall survive such termination.  In any such case either the Initial Purchasers or the Company shall have the right to postpone the Closing Date, as the case may be, but in no event for longer than seven days in order that the required changes, if any, to the Final Offering Memorandum or any other documents or arrangements may be effected.

As used in this Agreement, the term “Initial Purchaser” shall be deemed to include any person substituted for a defaulting Initial Purchaser under this Section 17.  Any action taken under this Section 17 shall not relieve any defaulting Initial Purchaser from liability in respect of any default of such Initial Purchaser under this Agreement.

SECTION 18. No Advisory or Fiduciary Responsibility.  The Company acknowledges and agrees that:  (i) the purchase and sale of the Securities pursuant to this Agreement, including the determination of the offering price of the Securities and any related discounts and commissions, is an arm’s-length commercial transaction between the Company, on the one hand, and the several Initial Purchasers, on the other hand, and the Company is capable of evaluating and understanding and understands and accepts the terms, risks and conditions of the transactions contemplated by this Agreement; (ii) in connection with each transaction contemplated hereby and the process leading to such transaction each Initial Purchaser is and has been acting solely as a principal and is not the agent or fiduciary of the Company or its affiliates, stockholders, creditors or employees or any other party; (iii) no Initial Purchaser has assumed or will assume an advisory or fiduciary responsibility in favor of the Company with respect to any of the transactions contemplated hereby or the process leading thereto (irrespective of whether such Initial Purchaser has advised or is currently advising the Company on other matters) or any other obligation to the Company except the obligations expressly set forth in this Agreement; (iv) the several Initial Purchasers and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company, and the several Initial Purchasers have no obligation to disclose any of such interests by virtue of any fiduciary or advisory relationship; and (v) the Initial Purchasers have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby, and the Company has consulted its own legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the several Initial Purchasers, or any of them, with respect to the subject matter hereof.  The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the several Initial Purchasers with respect to any breach or alleged breach of fiduciary duty.

SECTION 19. General Provisions.  This Agreement constitutes the entire agreement of the parties to this Agreement and supersedes all prior written or oral and all contemporaneous oral agreements, understandings and negotiations with respect to the subject matter hereof.  This Agreement may be executed in two or more counterparts, each one of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.  Delivery of an executed counterpart of a signature page to this Agreement by telecopier, facsimile or other electronic transmission (i.e., a “pdf” or “tif”) shall be effective as delivery of a manually executed counterpart thereof.  This Agreement may not be amended or modified unless in writing by all of the parties hereto, and no condition herein (express or implied) may be waived unless waived in writing by each party whom the condition is meant to benefit.  The section headings herein are for the convenience of the parties only and shall not affect the construction or interpretation of this Agreement.

If the foregoing is in accordance with your understanding of our agreement, kindly sign and return to the Company the enclosed copies hereof, whereupon this instrument, along with all counterparts hereof, shall become a binding agreement in accordance with its terms.

		Very truly yours,

Schedule A-1

EXHIBIT A

Form of opinion of counsel for the Company to be delivered pursuant to Section 5(c) of the Purchase Agreement.

(a) The Company is validly existing as a corporation and is in good standing under the laws of the State of Delaware, with full power and authority necessary to own or lease its properties and to conduct its business, in each case as described in the Pricing Disclosure Package and the Final Offering Memorandum in all material respects.

(b) The Company has all requisite corporate power and authority to execute, deliver and perform its obligations under the Indenture, the Securities and the Exchange Securities; the Indenture meets the requirements for qualification under the Trust Indenture Act; the Indenture has been duly and validly authorized by the Company and, when duly executed and delivered by the Company (assuming the due authorization, execution and delivery thereof by the Trustee), will constitute the valid and legally binding agreement of the Company, enforceable against the Company in accordance with its terms, except that the enforcement thereof may be subject to the Enforceability Exceptions.

(c) The Securities have been duly and validly authorized by the Company and, when duly executed and delivered by the Company and paid for by the Initial Purchasers in accordance with the terms of the Purchase Agreement (assuming the due authorization, execution and delivery of the Indenture by the Trustee and due authentication and delivery of the Securities by the Trustee in accordance with the Indenture), will constitute the valid and legally binding obligations of the Company, entitled to the benefits of the Indenture, and enforceable against the Company in accordance with their terms, except that the enforcement thereof may be subject to the Enforceability Exceptions.

(d) The Exchange Securities have been duly and validly authorized by the Company, and if and when the Exchange Securities are duly executed and delivered by the Company in accordance with the terms of the Registration Rights Agreement and the Indenture (assuming the due authorization, execution and delivery of the Indenture by the Trustee and due authentication and delivery of the Exchange Securities by the Trustee in accordance with the Indenture), will constitute the valid and legally binding obligations of the Company, entitled to the benefits of the Indenture, and enforceable against the Company in accordance with their terms, except that the enforcement thereof may be  subject to the Enforceability Exceptions.

(e) The Company has all requisite corporate power and authority to execute, deliver and perform its obligations under the Registration Rights Agreement; the Registration Rights Agreement has been duly and validly authorized by the Company and, when duly executed and delivered by the Company (assuming the due authorization, execution and delivery thereof by the Initial Purchasers), will constitute the valid and legally binding agreement of the Company, enforceable against the Company in accordance with its terms, except that (A) the enforcement thereof may be subject to the Enforceability Exceptions and (B) any rights to indemnity or contribution thereunder may be limited by federal and state securities laws and public policy considerations.

(f) The Company has all requisite corporate power and authority to execute, deliver and perform its obligations under the Purchase Agreement and to consummate the transactions contemplated thereby; the Purchase Agreement and the consummation by the Company of the transactions contemplated thereby have been duly and validly authorized by the Company.  The Purchase Agreement has been duly executed and delivered by the Company.

(g) The execution, delivery and performance of the Transaction Documents and the consummation of the transactions contemplated thereby (including, without limitation, the issuance and sale of the Securities to the Initial Purchasers) will not constitute or result in a breach or a default under (or an event that with notice or passage of time or both would constitute a default under) any of (i) any instrument to which the Company is a party and which is filed as an exhibit and set forth on the exhibit list to the Company’s Annual Report on Form 10-K for the year ended December 31, 2009 or any other report filed by the Company with the Commission under Section 13(a) of the Exchange Act after the date of such Annual Report on Form 10-K and through the dates of the Pricing Disclosure Package and the Final Offering Memorandum, which reports are incorporated by reference in the Pricing Disclosure Package and the Final Offering Memorandum, (ii) the restated certificate of incorporation or restated by-laws of the Company, or (iii) any statute or any judgment, order or regulation of any court or arbitrator or governmental or regulatory authority known to us, except, with respect to clauses (i) and (iii) only, for any such conflict, breach, violation or default that would not reasonably be expected to result in, individually or in the aggregate, a Material Adverse Change.  With respect to clause (iii) above, such counsel need express no opinion as to the applicability of any state securities or Blue Sky laws or federal or state antifraud laws, rules or regulations.

(h) No consent, approval, authorization or order of any governmental authority is required for the issuance and sale by the Company of the Securities to the Initial Purchasers or the consummation by the Company of the other transactions contemplated by the Purchase Agreement, except (i) such as may be required under Blue Sky laws, as to which such counsel need express no opinion, (ii) such as may be required under federal securities laws, as to which such counsel need express no opinion other than the opinion provided in paragraph (j) below, and (iii) those which have previously been obtained.

(i) The Company is not, and immediately after the sale of the Securities to be sold pursuant to the Purchase Agreement and the application of the proceeds from such sale (as described in the Pricing Disclosure Package and the Final Offering Memorandum under the caption “Use of Proceeds”) will not be, an “investment company” as such term is defined in the Investment Company Act.

(j) Assuming the accuracy of the representations, warranties and agreements of the Company and the Initial Purchasers contained in this Agreement, (A) no registration under the Securities Act of the Securities is required in connection with the sale of the Securities to the Initial Purchasers or in connection with the initial resale of the Securities by the Initial Purchasers, in each case as contemplated by the Purchase Agreement, the Pricing Disclosure Package and the Final Offering Memorandum, and (B) prior to the commencement of the Exchange Offer or the effectiveness of any registration statement prepared in connection with the Company’s obligations under the Registration Rights Agreement, the Indenture is not required to be qualified under the Trust Indenture Act.

(k) The statements under the captions “Description of Notes,” “Description of Other Indebtedness,” “Plan of Distribution,” “Transfer Restrictions” and “Certain United States Federal Income Tax Considerations” in the Pricing Disclosure Package and the Final Offering Memorandum, insofar as such statements relate to statements of law or summaries of documents referred to therein or of legal conclusions, have been reviewed by us and such statements of law and summaries of documents are accurate in all material respects.

In addition, such counsel shall also state that it has participated in conferences with representatives of the Company and with representatives of its independent accountants and independent reserve engineers at which conferences the contents of the Pricing Disclosure Package and the Final Offering Memorandum and any amendment and supplement thereto and related matters were discussed. Although such counsel has not undertaken to determine independently, and does not assume any responsibility for, or express any opinion regarding the accuracy, completeness or fairness of the statements contained in the Pricing Disclosure Package or the Final Offering Memorandum and any amendment or supplement thereto (except as expressly provided above), based upon the participation described above, nothing has come to the attention of such counsel to cause such counsel to believe that the Pricing Disclosure Package, as of the Time of Sale, or that the Final Offering Memorandum, as of its date or at the Closing Date, contained or contains any untrue statement of a material fact or omitted or omits to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. In making the foregoing statement, such counsel need not express any comment or belief with respect to the financial statements and notes and related schedules and other financial and accounting data and the oil and natural gas reserve estimates contained in or omitted from the Pricing Disclosure Package or the Final Offering Memorandum.

Summary

The following disclosure under “Summary—The Offering—Ranking” on page 5 and each other location where such information appears in the Preliminary Offering Memorandum is amended to read as follows:

At September 30, 2010, after giving effect to the issuance and sale of the Notes and the application of the estimated net proceeds therefrom as set forth under ‘‘Use of Proceeds,’’ we would have had total consolidated indebtedness of $637.5 million, consisting of $287.5 million of our outstanding 3.50% Senior Convertible Notes and $350 million of the Notes offered hereby, and we would have been able to incur an additional $677.5 million of secured indebtedness under our credit facility.

The following disclosure is added following “Table of Contents” on page i and in “Plan of Distribution” on page 150 of the Preliminary Offering Memorandum:

We expect delivery of the Notes will be made against payment therefor on or about February 7, 2011, which is the fifth business day following the date of pricing of the Notes (such settlement being referred to as “T+5”). Under Rule 15(c)6-1 of the Exchange Act, trades in the secondary market generally are required to settle in three business days unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes on the date of pricing of the Notes or during the next succeeding business day will be required, by virtue of the fact that the Notes initially will settle in T+5, to specify an alternate settlement cycle at the time of any such trade to prevent failed settlement and should consult their own advisers.
