Some of these include, but are not limited to, economic and competitive conditions, inflation rates, legislative and regulatory changes, financial market conditions, future business decisions, and other uncertainties, all of which are difficult to predict. There are numerous uncertainties inherent in estimating quantities of proved oil and gas reserves and in projecting future rates of production and timing of development expenditures.

Although Energen Resources makes use of futures, swaps and fixed-price contracts to mitigate risk, fluctuations in future oil and g as prices could affect materially our financial position and results of operation; furthermore, such risk mitigation activities may cause our financial position and results of operations to be materially different from results that would have been obtained has such risk mitigation activities not occurred.

The Debt Securities will be issued under an Indenture (the "Indenture") between the Corporation and The Bank of New York (the "Trustee"). A copy of the Indenture is filed as an exhibit to this Registration Statement. The following summaries of the Debt Securities and the Indenture do not purport to be complete andstate capital.

RECENT DEVELOPMENTS

In December 2001, we announced a change in this Prospectus. All capitalized terms not defined in this Prospectus shall have the definitions ascribedour fiscal year end from September 30 to them in the Indenture. Copies of the Indenture are available for inspection during normal business hours at the principal office of the Corporation or at the corporate trust office of the Trustee. GENERAL The Debt Securities will be direct, unsecured obligations of the Corporation and will rank pari passu with all outstanding unsecured senior indebtedness of the Corporation. The Indenture does not limit the aggregate principal amount of Debt Securities that may be issued thereunder and provides that Debt Securities may be issued thereunder from time to time in one or more series. All securities issued under the Indenture will rank equally and ratably with all other securities to be issued under such Indenture. The Corporation has previously issued $125,000,000 principal amount of its Medium-Term Notes, Series A under the Indenture, all of which are outstanding on the date hereof. The Debt Securities will be obligations exclusively of the Corporation. Since substantially all of the operations of the Corporation are conducted through its subsidiaries, principally Alagasco and Taurus, the Corporation's cash flow and consequently its ability to service debt is dependent upon the cash flow of its subsidiaries and the payment of funds by those subsidiaries in the form of dividends. The Prospectus Supplement and any related Pricing Supplement will describe certain terms of the Offered Debt Securities, including: (1) the title of the Offered Debt Securities; (2) any limit on the aggregate principal amount of the Offered Debt Securities; (3) the date or dates on which the principal of the Offered Debt Securities is payable; (4) the rate or rates per annum (which may be fixed or variable) at which the Offered Debt Securities will bear interest, if any, or any method by which such rate or rates shall be determined, and the date or dates from which such interest will accrue; (5) the date or dates on which interest, if any, on the Offered Debt Securities will be payable and the Regular Record Dates for any such Interest Payment Dates; (6) each office or agency where the principal of, and premium, if any, and any interest on the Offered Debt Securities will be payable and may be surrendered for registration of transfer or exchange; (7) the period or periods within which, 4 the price or prices at which, and the terms and conditions upon which the Offered Debt Securities may be redeemed, in whole or in part, at the option of the Corporation; (8) the obligation, if any, of the Corporation to redeem or purchase the Offered Debt Securities pursuant to any sinking fund or similar provisions or at the option of a Holder thereof and the period or periods within which, the price or prices at which and the terms and conditions upon which the Offered Debt Securities will be redeemed or purchased, in whole or in part, pursuant to any such obligation; (9) whether the Offered Debt Securities are to be issued in whole or in part in the form of one or more global notes, and, if so, the identity of the depositary for such global notes and the terms and conditions, if any, on which interests in such global notes may be exchanged for the individual securities represented thereby; (10) whether the Offered Debt Securities are to be issued with original issue discount within the meaning of section 1273(a) of the Internal Revenue Code of 1986, as amended (the "Code"), and the regulations thereunder and the amount of such discount; (11) the obligations or instruments which shall be considered to be Eligible Obligations in respect of Offered Debt Securities denominated in any currency other than United States Dollars or in a composite currency, and any additional or alternative provisions for the reinstatement of the Corporation indebtedness in respect of Offered Debt Securities after the satisfaction and discharge thereof; (12) any provisions for payment of additional amounts for taxes, and any provisions for redemption in the event the Corporation must comply with withholding tax or other tax reporting requirements in respect of an Offered Debt Security other than a Floating Rate Security ("Affected Security") or must pay such additional amounts in respect of any Offered Debt Security; (13) any index used to determine the amount of payment of principal of, and premium, if any, and any interest on the Offered Debt Securities; (14) the applicable Overdue Rate, if any; (15) any addition to, or modification or deletion of, any Events of Default or covenants provided forDecember 31. This change became effective with respect to the Offered Debt Securities; (16) if the principal of or premium, if any, or interest, if any, on the Offered Debt Securitiesthree-month transition period ending December 31, 2001. References to "fiscal year 2001" in this prospectus are to be payable, at the election of the Corporation or a Holder thereof, in a coin or currency other than that in which the Debt Securities are stated to be payable, the period or periods within which,year ended September 30, 2001.

On April 8, 2002, we acquired certain oil and the terms and conditions upon which, such election may be made; (17) the currency or currencies, including composite currencies, in which payment of the principal of and premium, if any, and interest, if any, on the Offered Debt Securities shall be payable (if other than the currency of the United States); (18) if the principal of or premium, if any, or interest on the Offered Debt Securities are to be payable, or are to be payable at the election of the Corporation or a Holder thereof, in securities or other property, the type and amount of such securities or other property, or the method by which such amount shall be determined, and the period or periods within which, and the terms and conditions upon which, any such election may be made; (19) the terms, if any, pursuant to which the Offered Debt Securities may be converted into or exchanged for shares of capital stock or other securities of the Corporation; and (20) any other terms and provisions of the Offered Debt Securities which are not inconsistent with the Indenture.

The Indenture provides that all Debt Securities of any one series need not be issued at the same time and that the Corporation may, from time to time, issue additional Debt Securities of a previously issued series. In addition, the Indenture provides that the Corporation may issue Debt Securities with terms different from those of any other series of Debt Securities and, within a series of Debt Securities, terms (such as interest rate or manner in which interest is calculated, original issue date, redemption provisions and maturity date) may differ. 5 CERTAIN CONDITIONS FOR ISSUANCE OF ADDITIONAL INDEBTEDNESS Pursuant to Section 234 of the Constitution of Alabama of 1901, the bonded indebtedness of Alabama corporations may not be increased without the consent of shareholders. The Corporation is presently authorized to issue, without further shareholder approval, bonded indebtedness in an amount which, when added to the bonded indebtedness then outstanding, does not exceed the greater of (i) $750,000,000 or (ii) one hundred fifty percent (150%) of the total shareholders' equity of the Corporation as reflected in the consolidated financial statements of the Corporation as of the end of the Corporation's most recently completed fiscal quarter.

Except as described in (d) and (e) above, no Event of Default with respect to the Debt Securities of one series necessarily constitutes an Event of Default with respect to the Debt Securities of any other series issued under the Indenture. REMEDIES If any Event of Default with respect to the Debt Securities of any series occurs and is continuing, either the Trustee or the Holders of at least 33% in aggregate principal amount of all the Outstanding Debt Securities of that series may declare the principal amount of all the Outstanding Debt Securities of that series to be due and payable immediately; provided, however, that if an Event of Default occurs and is continuing with respect to more than one series of Debt Securities, the Trustee or the Holders of not less than 33% in aggregate principal amount of the Outstanding Debt Securities of all such series, considered as one class, may make such declaration of acceleration and not the Holders of the Debt Securities of any one of such series. 7 The Holders of a majority in aggregate principal amount of the Outstanding Debt Securities of each series may, on behalf of all Holders of the Debt Securities of that series, waive any past default and its consequences under the Indenture with respect to the Debt Securities of that series, except a default in the payment of principal or premium or interest, if any, on any Debt Security of that series, or in respect of a provision of the Indenture which cannot be amended or modified without the consent of the Holder of each Outstanding Debt Security of the series affected. At any time after the declaration of acceleration with respect to Debt Securities of any series has been made, but before a judgment or decree for the payment of money due has been obtained, the Event or Events of Default giving rise to such declaration of acceleration shall, without further act, be deemed to have been waived, and such declaration and its consequences shall, without further act, be deemed to have been rescinded and annulled if (a) the Corporation has paid or deposited with the Trustee a sum sufficient to pay (1) all overdue interest on all of such Debt Securities; (2) the principal of and premium, if any, on any of such Debt Securities which have become due otherwise than by such declaration of acceleration and interest thereon at the rate or rates prescribed therefor in such Debt Securities; (3) to the extent that payment of such interest is lawful, interest upon overdue interest at the rate or rates prescribed therefor in such Debt Securities; (4) all amounts due to the Trustee under the Indenture; and (b) any other Events of Default with respect to the Debt Securities of such series, other than the nonpayment of the principal of such Debt Securities which has become due solely by such declaration of acceleration, have been cured or waived as provided in the Indenture.

Subject to such provisions for the indemnification of the Trustee and subject to certain other limitations, the Holders of a majority in aggregate principal amount of the Outstanding Debt Securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Debt Securities of that series; provided, however, that if an Event of Default occurs and is continuing with respect to more than one series of Debt Securities, the Holders of a majority in aggregate principal amount of the outstanding Debt Securities of all such series, considered as one class, will have the right to make such direction, and not the Holders of the Debt Securities of any one of such series; and provided, further, that (a) such direction will not be in conflict with any rule of law or with the Indenture and would not involve the Trustee in personal liability in circumstances where reasonable indemnity would not, in the Trustee's sole discretion, be adequate, (b) the Trustee shall not have determined that the action so directed would be unjustly prejudicial to the Holders not taking part in such direction and, (c) the Trustee may take any other action it deems proper which is not inconsistent with such direction. The right of a Holder of any Debt Security of such series to institute a proceeding with respect to the Indenture is subject to certain conditions precedent, but each Holder has an absolute right to receive payment of principal and premium and interest, if any, when due and to institute suit for the enforcement of any such payment. The Indenture provides that the Trustee, within 90 days after the occurrence of any default thereunder with respect to the Debt Securities of a series, is required to give the Holders of the Debt Securities of such series notice of any default known to it, unless cured or waived; provided, however, that, except in the case of a default in the payment of principal of or premium or interest, if any, on any Debt Securities of such series, the Trustee may withhold such notice if the Trustee determinesgood faith, that it is in the best interest of us and our shareholders to defer disclosure of non-public information until such Holdersinformation has reached a more advanced state.

(b) The Corporation does hereby indemnify any officer or director of the Corporation who was, or is, a party, or is threatened to be made a party, to any threatened, pending, or completed claim or action by, or in the right of, the Corporation to procure a judgment in its favor by reason of the fact that he is or was a director, an officer, an employee, or an agent of the Corporation, or is or was serving at the request of the Corporation as a director, officer, partner, employee, or agent of another corporation, partnership, joint venture, trust, or other enterprise against expenses, including attorneys' fees, actually and reasonably incurred by him in connection with the defense or settlement of such action if he acted in good faith and in a manner he reasonably believed to be in, or not opposed to, the best interests of the Corporation, except that no indemnification shall be made in respect of any claim, issue, or matter as to which such person shall have been adjudged to be liable for negligencenegl igence or misconduct in the performance of his duty to the Corporation unless, and only to the extent that the court in which such action was brought shall determine upon application that, despite the adjudication of liability but in view of all circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which such court shall deem proper.
