(v) to the knowledge of such counsel, there is no pending or threatened action, suit or proceeding before any court or governmental agency, authority or body or any arbitrator involving the Company or any of its subsidiaries, of a character required to be disclosed in the Registration Statement which is not adequately disclosed in the Prospectus, and there is no franchise, contract or other document of a character required to be described in the Registration Statement or Prospectus, or to be filed as an exhibit, which is not described or filed as required; and the statements included or incorporated in the Prospectus describing any material contracts or agreements relating to the Company fairly summarize such matters;

(vi) the Registration Statement has become effective under the Act; any required filing of the Preliminary Prospectus and the Prospectus, and any supplements thereto, pursuant to Rule 424(b) has been made in the manner and within the time period required by Rule 424(b); to the knowledge of such counsel, no stop order suspending the effectiveness of the Registration Statement has been issued, no proceedings for that purpose have been instituted or threatened, and the Registration Statement and the Prospectus (other than the financial statements and other financial and statistical information derived from such financial statements contained therein as to which such counsel need express no opinion) comply as to form in all material respects with the applicable requirements of the Securities Act and the Exchange Act and the respective rules thereunder; and such counsel has no reason to believe that at the effective date of the Registration Statement, the Registration Statement contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein, or necessary to make the statements therein not misleading or that the Prospectus includes any untrue statement of a material fact 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;

(vii) this Agreement has been duly authorized, executed and delivered by the Company;

(viii) the Company had full power and authority to execute the Indenture and the Indenture has been duly authorized, executed and delivered by the Company, has been duly qualified under the Trust Indenture Act, and assuming due authorization, execution and delivery thereof by the Trustee, constitutes a valid and legally binding instrument enforceable against the Company in accordance with its terms, except as the same may be limited by (i) bankruptcy, insolvency, reorganization, fraudulent transfer, fraudulent conveyance, moratorium or other similar laws affecting the enforcement of creditors' rights and remedies generally and (ii) the application of general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law), including, without limitation, (x) the possible unavailability of specific performance, injunctive relief or any other remedy and (y) concepts of materiality, reasonableness, good faith and fair dealing.

(ix) no consent, approval, authorization or order of any court or governmental agency or body is required for the consummation of the transactions contemplated herein, except such as have been obtained under the Securities Act and the Trust Indenture Act and such as may be required under the blue sky laws of any jurisdiction in connection with the purchase and distribution of the Securities by the Underwriters and such other approvals (specified in such opinion) as have been obtained;

(xi) the Company is exempt from all provisions of the Holding Company Act except Section 9(a)(2) thereof;

(xii) the Company is not an "investment company," as such term is defined in the Investment Company Act of 1940, as amended; and

(xiii) the statements made in the Prospectus under "Description of Debt Securities" and "Description of the Notes," insofar as they purport to constitute summaries of the terms of the Securities, constitute accurate summaries of the terms of such documents in all material respects.

In rendering such opinion, such counsel may rely (A) as to matters involving the application of laws of any jurisdiction other than the State of Alabama or the United States, to the extent deemed proper and specified in such opinion, upon the opinion of other counsel of good standing believed to be reliable and who are satisfactory to counsel for the Underwriters and (B) as to matters of fact, to the extent deemed proper, on certificates of responsible officers of the Company and public officials. References to the Prospectus in this paragraph (b) include any supplements thereto at the Time of Delivery.

(iii) on the basis of (A) performing procedures as specified by the American Institute of Certified Public Accountants for a review of interim financial information as described in Statement on Auditing Standard No. 100, Interim Financial Information, on the unaudited consolidated balance sheets as of March 31, 2003 and June 30, 2003, the unaudited consolidated statements of income for the three-month period ended March 31, 2003 and for the three- and six-month periods ended June 30, 2003 and the unaudited consolidated statements of cash flows for the three-month period ended March 31, 2003 and the six-month period ended June 30, 2003, and as described in Statement on Auditing Standard No. 71, Interim Financial Information, on the unaudited consolidated statements of income for the three-month period ended March 31, 2002 and for the three- and six-month periods ended June 30, 2002 and the unaudited consolidated statements of cash flows for the three-month period ended March 31, 2002 and the six-month period ended June 30, 2002, of the Company incorporated by reference in the Registration Statement and the Prospectus as amended or supplemented and included in the Company's quarterly reports on Form 10-Q filed by the Company with the Commission under Section 13 of the Exchange Act, (B) a reading of the minutes of meetings of the Board of Directors, the Finance Committee thereof and shareholders of the Company and its subsidiaries since the close of the most recent audited fiscal year as set forth in the minute books through a specified date and (C) making inquiries of certain officials of the Company and its subsidiaries who have responsibility for financial and accounting matters (it being understood that the foregoing procedures do not constitute an audit made in accordance with generally accepted auditing standards and they would not necessarily reveal matters of significance with respect to the comments made in such letter, and accordingly that they make no representation as to the sufficiency of such procedures for the Underwriters' purposes), nothing has come to their attention that caused them to believe that (1) the unaudited consolidated financial statements of the Company included or incorporated by reference in the Registration Statement and the Prospectus as amended or supplemented do not comply as to form in all material respects with the accounting requirements of the Securities Act or the Exchange Act and the published rules and regulations thereunder or that any material modifications should be made to said unaudited consolidated financial statements included in or incorporated by reference in the Registration Statement and the Prospectus as amended or supplemented for them to be in conformity with generally accepted accounting principles or (2) at the date of the latest available financial statements of the Company, if any, there was any change in the common stock or increase in long-term debt of the Company and its subsidiaries, or any decrease in total common stock equity or net current assets of the Company and its subsidiaries (other than as occasioned by the declaration of regular dividends), as compared with amounts shown in the most recent consolidated balance sheet included or incorporated by reference in the Registration Statement and the Prospectus as amended or supplemented, except in all instances for such changes or decreases that the Registration Statement and the Prospectus as amended or supplemented disclose have occurred or may occur or that are described in such letter or (3) at a date subsequent to the date of the latest available financial statements of the Company, if any, and not more than five days prior to the date of such letter, there was any change in the common stock or increase in long-term debt of the Company and its subsidiaries, as compared with amounts shown in the most recent consolidated balance sheet included or incorporated by reference in the Registration Statement and the Prospectus as amended or supplemented, except in all instances for such changes or decreases that the Registration Statement and the Prospectus as amended or supplemented disclose have occurred or may occur or that are described in such letter; and (iv) they have carried out certain procedures and made certain findings, as specified in such letter, with respect to certain amounts included in the Registration Statement and the Prospectus as amended or supplemented (including Exhibit 12 to the Registration Statement) and such other items as the Representatives may reasonably request;

Since the respective dates as of which information is given in the Prospectus as amended prior to the date of this Agreement, (i) neither the Company nor any of its subsidiaries shall have sustained any loss or interference with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree, otherwise than as set forth or contemplated in the Prospectus as amended prior to the date of this Agreement and (ii) there shall not have been any change in the capital stock or long-term debt of the Company or any of its subsidiaries or any change in or affecting the general affairs, management, financial position, shareholders' equity or results of operations of the Company and its subsidiaries, otherwise than as set forth or contemplated in the Prospectus as amended prior to the date of this Agreement, the effect of which, in any such case described in clause (i) or (ii), is in the judgment of the Representatives so material and adverse as to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Securities on the terms and in the manner contemplated in the Prospectus as first amended or supplemented relating to the Securities;

On or prior to the Time of Delivery, the Company shall have furnished or caused to be furnished to the Representatives satisfactory evidence that the Securities have received ratings of at least A- by Standard & Poor's and at least Baa1 by Xxxxx'x Investors Service, Inc., and that such ratings are in effect; and since the date of this Agreement (i) no downgrading shall have occurred in the rating accorded the Company's debt securities by any "nationally recognized statistical rating organization," as that term is defined by the Commission for purposes of Rule 436(g)(2) under the Securities Act and (ii) no such organization shall have publicly announced that it has under surveillance or review, with possible negative implications, its rating of any of the Company's debt securities;

On or after the date of this Agreement there shall not have occurred any of the following: (i) a suspension or material limitation in trading in securities generally on the New York Stock Exchange; (ii) a suspension or material limitation in trading in the Company's securities on New York Stock Exchange; (iii) a general moratorium on commercial banking activities declared by either Federal or New York State authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States; (iv) the outbreak or escalation of hostilities involving the United States or the declaration by the United States of a national emergency or war; or (v) the occurrence of any other calamity or crisis or any change in financial, political or economic conditions in the United States or elsewhere, if the effect of any such event specified in clause (iv) or (v) in the judgment of the Representatives makes it impracticable or inadvisable to proceed with the public offering or the delivery of the Securities on the terms and in the manner contemplated in the Prospectus as first amended or supplemented relating to the Securities;

The Company shall have complied with the provisions of Section 5(c) hereof with respect to the furnishing of prospectuses on the Business Day next succeeding the date of this Agreement; and

The Company shall have furnished or caused to be furnished to the Representatives at the Time of Delivery a certificate or certificates of officers of the Company satisfactory to the Representatives as to the accuracy of the representations and warranties of the Company herein at and as of the Time of Delivery, as to the performance by the Company of all of its obligations hereunder to be performed at or prior to the Time of Delivery, as to the matters set forth in subsections (a) and (e) of this Section and as to such other matters as the Representatives may reasonably request.

The Company agrees to indemnify and hold harmless each Underwriter, its officers, directors, employees and agents and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act as follows:

(i) Against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto) or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus or the Prospectus (or any amendment or supplement thereto) or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii) Against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, if such settlement is effected with the written consent of the Company; and

(iii) Against any and all expense whatsoever, as incurred (including, subject to Section 8(c) hereof, the fees and disbursements of counsel chosen by the Representatives), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under paragraph (i) or (ii) above; and any and all expense whatsoever incurred for appearing as a witness in any third-party litigation or proceeding relating to this Agreement;

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use in the Registration Statement (or any amendment thereto) or any Preliminary Prospectus or the Prospectus (or any amendment or supplement thereto); provided further, however, that this indemnity shall not inure to the benefit of any Underwriter and each person if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act on account of any loss, liability, claim, damage or expense arising from the sale of the Securities to any person if a copy of the Prospectus, as the same may then be supplemented or amended (excluding, however, any document then incorporated or deemed incorporated therein by reference), was not sent or given by or on behalf of such Underwriter to such person with or prior to the written confirmation of the sale involved and the alleged omission or alleged untrue statement was corrected in the Prospectus as supplemented or amended at the time of such confirmation, unless the failure to send or give the Prospectus as so amended or supplemented resulted from the Company's failure to comply with Section 5(a) hereof.

Each Underwriter, acting severally and not jointly, agrees to indemnify and hold harmless the Company, its directors, each of its officers who signed the Registration Statement (or any amendment thereto), and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in Section 8(a) hereof as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto) or any Preliminary Prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives expressly for use in the Registration Statement (or any amendment thereto) or such Preliminary Prospectus or the Prospectus (or any amendment or supplement thereto).

Each indemnified party shall give prompt notice to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability that it may have otherwise than on account of this indemnity agreement. An indemnifying party may participate at its own expense in the defense of such action. If it so elects within a reasonable time after receipt of such notice, an indemnifying party, jointly with any other indemnifying parties receiving such notice, may assume the defense of such action with counsel chosen by it satisfactory to such indemnified parties in such action. If an indemnifying party assumes the defense of such action, the indemnifying parties shall not be liable for any fees and expenses of counsel for the indemnified parties incurred thereafter in connection with such action; provided, however, that if such indemnified parties reasonably object to such assumption on the ground that there may be legal defenses available to them that are different from or in addition to those available to such indemnifying party, then the fees and expenses of one separate counsel in addition to local counsel, if any, for the indemnified parties shall be paid by the indemnifying parties. In no event shall the indemnifying parties be liable for the fees and expenses of more than one counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances.

If the indemnification provided for in Section 8(a) or 8(b) hereof is unavailable to an indemnified party or insufficient to hold harmless an indemnified party in respect of any loss, liability, claim, damage or expense referred to therein, then each indemnifying party under such Section, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such loss, liability, claim, damage or expense in such proportion as is appropriate to reflect (i) the relative benefits received by the Company and the Underwriters from the offering of the Securities, (ii) the relative fault of the Company and of the Underwriters in connection with the statements or omissions that resulted in such loss, liability, claim, damage or expense and (iii) any other relevant equitable considerations. The relative benefits received by the Company and the Underwriters shall be determined by reference to the respective proportions that the net proceeds from the offering (before deducting expenses) received by the Company and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the Prospectus as amended or supplemented, bear to the aggregate public offering price of the Securities. The relative fault of the Company and the Underwriters shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties' relative intent, 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 contribution pursuant to this Section 8 were 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 account of the equitable considerations referred to in Section 8(d) hereof. The amount paid or payable by an indemnified party as a result of the loss, liability, claim, damage and expense referred to in Section 8(d) hereof shall be deemed to include, subject to the limitations set forth above, 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, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The obligation of each Underwriter, acting severally and not jointly, to contribute pursuant to this Section 8 shall be in the proportion that its underwriting obligation hereunder bears to the underwriting obligations of all other Underwriters. The obligations of each of the Company and the Underwriters under this Section 8 shall be in addition to any liability that the Company and the respective Underwriters, as the case may be, may otherwise have. For purposes of this Section 8, each person, if any, who controls an Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Company.

If any Underwriter shall default in its obligation to purchase the Securities that it has agreed to purchase under this Agreement, the Representatives may in their discretion arrange for themselves or another party or other parties to purchase such Securities on the terms contained herein. If within 36 hours after such default by any Underwriter the Representatives do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of 36 hours within which to procure another party or other parties satisfactory to the Representatives to purchase such Securities on such terms. In the event that, within the respective prescribed period, the Representatives notify the Company that they have so arranged for the purchase of such Securities, or the Company notifies the Representatives that it has so arranged for the purchase of such Securities, the Representatives or the Company shall have the right to postpone the Time of Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus as amended or supplemented, or in any other documents or arrangements, and the Company agrees to file promptly any amendments or supplements to the Registration Statement or the Prospectus that in the opinion of the Representatives may thereby be made necessary. The term "Underwriter" as used in this Agreement shall include any person substituted under this Section 9 with like effect as if such person had originally been a party to this Agreement.

If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in Section 9(a) hereof, the aggregate principal amount of such Securities that remains unpurchased does not exceed one-eleventh of the aggregate principal amount of the Securities, then the Company shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Securities that such Underwriter agreed to purchase under this Agreement and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the principal amount of Securities that such Underwriter agreed to purchase under this Agreement) of the Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in Section 9(a) hereof, the aggregate principal amount of Securities that remains unpurchased exceeds one-eleventh of the aggregate principal amount of the Securities, as referred to in Section 9(b) hereof, or if the Company shall not exercise the right described in Section 9(b) hereof to require non-defaulting Underwriters to purchase Securities of a defaulting Underwriter or Underwriters, then this Agreement shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Company, except for the expenses to be borne by the Company and the Underwriters as provided in Section 6 hereof and the indemnity and contribution agreements in Section 8 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

The respective indemnities, agreements, representations, warranties and other statements of the Company and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter or any controlling person of any Underwriter, or the Company, or any officer or director or controlling person of the Company, and shall survive delivery of and payment for the Securities.

If this Agreement shall be terminated pursuant to Section 9 or if the Securities are not delivered by or on behalf of the Company solely as a result of the failure to satisfy the condition set forth in Section 7(g) hereof, the Company shall not then be under any liability to any Underwriter with respect to the Securities covered by this Agreement except as provided in Sections 6 and 8 hereof; but, if for any other reason the Securities are not delivered by or on behalf of the Company as provided herein, the Company will reimburse the Underwriters through the Representatives for all out-of-pocket expenses approved in writing by the Representatives, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Securities, but the Company shall then be under no further liability to any Underwriter with respect to such Securities except as provided in Sections 6 and 8 hereof.

In all dealings hereunder, the Representatives of the Underwriters of Securities shall act on behalf of each of such Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by such Representatives jointly or by such of the Representatives, if any, as may be designated for such purpose in this Agreement.

All statements, requests, notices and agreements hereunder shall be in writing, and if to the Underwriters shall be delivered or sent by mail or facsimile transmission to the address of the Representatives as set forth in this Agreement; and if to the Company shall be delivered or sent by mail or facsimile transmission to the address of the Company set forth in the Registration Statement: Attention: Secretary; provided, however, that any notice to an Underwriter pursuant to Section 8(c) hereof shall be delivered or sent by mail or facsimile transmission to such Underwriter at its address set forth in its Underwriters' Questionnaire, or telex constituting such Questionnaire, which address will be supplied to the Company by the Representatives upon request. Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

This Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters, the Company and, to the extent provided in Sections 8 and 10 hereof, the officers and directors of the Company and each person who controls the Company or any Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of any of the Securities from any Underwriter shall be deemed a successor or assign by reason merely of such purchase.

This Agreement shall be governed by and construed in accordance with the laws of the State of New York.

This Agreement may be executed by any one or more of the parties hereto and thereto in any number of counterparts, each of which shall be deemed to be an original, but all such respective counterparts shall together constitute one and the same instrument.

If the foregoing is in accordance with your understanding, please sign and return to us counterparts hereof.

Very truly yours,

Energen Corporation
