NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS
ENERGEN CORPORATION AND ALABAMA GAS CORPORATION

1. BASIS OF PRESENTATION

The unaudited financial statements and notes should be read in conjunction with the financial statements and notes thereto for the years ended December 31, 2004, 2003 and 2002 included in the 2004 Annual Report of Energen Corporation (the Company) and Alabama Gas Corporation (Alagasco) on Form 10-K. Alagasco has a September 30 fiscal year for rate-setting purposes (rate year) and reports on a calendar year for the Securities and Exchange Commission and all other financial accounting reporting purposes. The accompanying unaudited condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the disclosures required for complete financial statements. The year-end consolidated condensed balance sheet data included in the interim report was derived from audited financial statement s but does not include all annual disclosures required by accounting principles generally accepted in the United States of America. The Company's natural gas distribution business is seasonal in character and influenced by weather conditions. Results of operations for interim periods are not necessarily indicative of the results that may be expected for the year.

The quarterly information reflects the application of Statement of Financial Accounting Standard (SFAS) No. 144, "Accounting for Impairment or Disposal of Long-Lived Assets." SFAS No. 144 requires that gains and losses from the sale of certain oil and gas properties and write-downs of certain properties held-for-sale be reported as discontinued operations, with income or loss from operations of the associated properties reported as income or loss from discontinued operations in the current and prior periods. All other adjustments to the unaudited financial statements that are, in the opinion of management, necessary for a fair statement of the results of operations for the interim periods have been recorded. Such adjustments consisted of normal recurring items. Certain reclassifications were made to conform prior years' financial statements to the current-quarter presentation.

2. STOCK-BASED COMPENSATION

The Company adopted the fair value recognition provisions of SFAS No. 123 (as amended), "Accounting for Stock-Based Compensation," prospectively for all stock-based employee compensation effective as of January 1, 2003. Awards under the Company's plan vest over periods ranging from one to six years. The cost related to stock-based employee compensation included in the determination of net income for the three months ended March 31, 2005 and 2004, approximates that which would have been recognized if the fair value method had been applied to all awards since the original effective date of SFAS No. 123. The following table illustrates the effect on net income and diluted and basic earnings per share as if the fair value based method had been applied to all outstanding and unvested awards in each period:

	Three months ended March 31,

*Share and per share data have not been restated to reflect a 2-for-1 stock split payable June 1, 2005 (see Note 15)

3. REGULATORY

All of Alagasco's utility operations are conducted in the state of Alabama. Alagasco is subject to regulation by the Alabama Public Service Commission (APSC) which established the Rate Stabilization and Equalization (RSE) rate-setting process in 1983. RSE was extended with modifications in 2002, 1996, 1990, 1987 and 1985. On June 10, 2002, the APSC extended Alagasco's rate-setting methodology, RSE, without change, for a six-year period through January 1, 2008. Under the terms of that extension, RSE will continue after January 1, 2008, unless, after notice to the Company and a hearing, the Commission votes to either modify or discontinue its operation. Alagasco is on a September 30 fiscal year for rate-setting purposes (rate year) and reports on a calendar year for the Securities and Exchange Commission and all other financial accounting reporting purposes. Alagasco's allowed range of return on average equity remains 13.15 percent to 13.65 percent throughout the term of the order, subje ct to change in the event that the Commission, following a generic rate of return hearing, adjusts the equity returns of all major energy utilities operating under a similar methodology. Under RSE the APSC conducts quarterly reviews to determine, based on Alagasco's projections and year-to-date performance, whether Alagasco's return on average equity at the end of the rate year will be within the allowed range of return. Reductions in rates can be made quarterly to bring the projected return within the allowed range; increases, however, are allowed only once each rate year, effective December 1, and cannot exceed 4 percent of prior-year revenues. Alagasco did not have a reduction in rates related to the return on average equity for the rate year ended 2004. As of September 30, 2003, Alagasco had a $3 million reduction in revenues to bring the return on average equity within the allowed range of return. A $12.3 million and an $11.2 million annual increase in revenues became effective December 1, 2004 and 2003 , respectively. RSE limits the utility's equity upon which a return is permitted to 60 percent of total capitalization and provides for certain cost control measures designed to monitor Alagasco's operations and maintenance (O&M) expense. Under the inflation-based cost control measurement established by the APSC, if the percentage change in O&M expense per customer falls within a range of 1.25 points above or below the percentage change in the Consumer Price Index For All Urban Consumers (index range), no adjustment is required. If the change in O&M expense per customer exceeds the index range, three-quarters of the difference is returned to customers. To the extent the change is less than the index range, the utility benefits by one-half of the difference through future rate adjustments. The increase in O&M expense per customer was above the index range for the rate year ended September 30, 2004; as a result, the utility returned $1.2 million pre-tax to customers through rate adjustments und er the provisions of RSE.

Alagasco calculates a temperature adjustment to customers' monthly bills to substantially remove the effect of departures from normal temperatures on Alagasco's earnings. Adjustments to customers' bills are made in the same billing cycle in which the weather variation occurs. The temperature adjustment applies primarily to residential, small commercial and small industrial customers. This adjustment, however, is subject to certain limitations including regulatory limits on adjustments to increase customers' bills, the impact of non-temperature weather conditions such as wind velocity or cloud cover and the impact of any elasticity of demand as a result of high commodity prices. Alagasco's rate schedules for natural gas distribution charges contain a Gas Supply Adjustment (GSA) rider, established in 1993, which permits the pass-through to customers of changes in the cost of gas supply.

4. DERIVATIVE COMMODITY INSTRUMENTS

Energen Resources Corporation, Energen's oil and gas subsidiary, periodically enters into derivative commodity instruments that qualify as cash flow hedges under SFAS No. 133," Accounting for Derivative Instruments and Hedging Activities," to hedge its exposure to price fluctuations on oil, natural gas and natural gas liquids production. In addition, Alagasco periodically enters into cash flow derivative commodity instruments to hedge its exposure to price fluctuations on its gas supply. Such instruments may include regulated natural gas and crude oil futures contracts traded on the New York Mercantile Exchange (NYMEX) and over-the-counter swaps, collars and basis hedges with major energy derivative product specialists. The counterparties to the commodity instruments are investment banks and energy-trading firms. In some contracts, the amount of credit allowed before collateral must be posted for out-of-the-money hedges varies depending on the credit rating of the Company or Alagasco. In cases where this arrangement exists, generally the credit ratings must be maintained at investment grade status to have available counterparty credit.

Energen Resources applies SFAS No. 133 which requires all derivatives to be recognized on the balance sheet and measured at fair value. If a derivative is designated as a cash flow hedge, the effectiveness of the hedge, or the degree that the gain (loss) for the hedging instrument offsets the loss (gain) on the hedged item is measured at each reporting period. The effective portion of the gain or loss on the derivative instrument is recognized in other comprehensive income (OCI) as a component of equity and subsequently reclassified into earnings as operating revenues when the forecasted transaction affects earnings. The ineffective portion of a derivative's change in fair value is required to be recognized in earnings immediately. Derivatives that do not qualify for hedge treatment under SFAS No. 133 must be recorded at fair value with gains or losses recognized in operating revenues in the period of change.

As of March 31, 2005, $74 million, net of tax, of deferred net losses on derivative instruments recorded in accumulated other comprehensive income are expected to be reclassified to operating revenues during the next 12-month period. The actual amounts that will be reclassified to earnings over the next year could vary materially from this amount due to changes in market conditions. Gains and losses on derivative instruments that are not accounted for as cash flow hedges as well as the ineffective portion of the change in fair value of derivatives accounted for as cash flow hedges, are included in operating revenues in the consolidated financial statements. For the ineffective portion of the change in fair value of derivatives accounted for as cash flow hedges, Energen Resources recorded a $1.2 million after-tax loss for the three months ended March 31, 2005. Also, Energen Resources recorded an after-tax loss of $9.7 million for the quarter on contracts that did not meet the definition of cash flow hedges under SFAS No. 133. As of March 31, 2005, the Company had 8.38 billion cubic feet (Bcf) of gas hedges with a fair value pretax loss of $15.1 million which expire by year-end that did not meet the definition of a cash flow hedge but are considered by the Company to be viable economic hedges. The Company had $52.7 million and $15.6 million included in current and noncurrent deferred income taxes on the consolidated balance sheets related to OCI as of March 31, 2005 and December 31, 2004, respectively.

Energen Resources has entered into the following transactions for the remainder of 2005 and subsequent years:
Production Period	Total Hedged Volumes	Average Contract Price	Description

* Average contract prices are not meaningful due to the varying nature of each contract.

All hedge transactions are subject to the Company's risk management policy, approved by the Board of Directors, which does not permit speculative positions. The Company formally documents all relationships between hedging instruments and hedged items, as well as its risk management objective and strategy for undertaking the hedge. This process includes specific identification of the hedging instrument and the hedge transaction, the nature of the risk being hedged and how the hedging instrument's effectiveness in hedging the exposure to the hedged transaction's variability in cash flows attributable to the hedged risk will be assessed. Both at the inception of the hedge and on an ongoing basis, the Company assesses whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in cash flows of hedged items. The Company discontinues hedge accounting if a derivative has ceased to be a highly effective hedge. The maximum term over which Energen Resourc es has hedged exposures to the variability of cash flows is through December 31, 2006.

On December 4, 2000, the APSC authorized Alagasco to engage in energy risk-management activities to manage the utility's cost of gas supply. As required by SFAS No. 133, Alagasco recognizes all derivatives as either assets or liabilities on the balance sheet with a corresponding regulatory asset or liability. Any gains or losses are passed through to customers using the mechanisms of the GSA in compliance with Alagasco's APSC-approved tariff. In accordance with SFAS No. 71, Alagasco recorded an $11.6 million gain as a regulatory liability with a corresponding asset in prepayments and other of $11.6 million representing the fair value of derivatives as of March 31, 2005. Alagasco recorded an $8.1 million gain as an asset in prepayments and other with a corresponding current regulatory liability of $8.1 million representing the fair value of derivatives as of December 31, 2004.

8. LONG-LIVED ASSETS AND DISCONTINUED OPERATIONS The Company applies SFAS No. 144, which retains the previous asset impairment requirements of SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of," for loss recognition when the carrying value of an asset exceeds the sum of the undiscounted estimated future cash flows of the asset. In addition, SFAS No. 144 requires that gains and losses on the sale of certain oil and gas properties and writedowns of certain properties held-for-sale be reported as discontinued operations, with income or loss from operations of the associated properties reported as income or loss from discontinued operations. The results of operations for held-for-sale properties are reclassified and reported as discontinued operations for prior periods in accordance with SFAS No. 144. Energen Resources may, in the ordinary course of business, be involved in the sale of developed or undeveloped properties. All assets held-for-sale must be reported at the lower of the carrying amount or fair value. In the current quarter, Energen Resources recorded a pre-tax gain of $198,000 primarily from a property sale located in the Permian Basin. Energen Resources had no property sales during the three months ended March 31, 2004. The following are the results of operations from discontinued operations:

10. COMMITMENTS AND CONTINGENCIES Commitments and Agreements: Certain of Alagasco's long-term gas procurement contracts for the supply, storage and delivery of natural gas include fixed charges of approximately $249.7 million through October 2013. Alagasco also is committed to purchase minimum quantities of gas at market-related prices or to pay certain costs in the event the minimum quantities are not taken. These purchase commitments are approximately 110.5 Bcf through December 2014. Alagasco purchases gas as an agent for certain of its large commercial and industrial customers. Alagasco has in certain instances provided commodity-related guarantees to the counterparties in order to facilitate these agency purchases. Liabilities existing for gas delivered to customers subject to these guarantees are included in the consolidated balance sheet. In the event the customer for whom the guarantee was entered fails to take delivery of the gas, Alagasco can sell such gas for the customer, with the customer liable for any resulting loss. Although the substantial majority of purchases under these guarantees are for the customers' current monthly consumption and are at current market prices, in some instances, the purchases are for an extended term at a fixed price. At March 31, 2005, the fixed price purchases under these guarantees had a maximum term outstanding through March 2006 and an aggregate purchase price of $8.8 million with a market value of $10.8 million. Legal Matters: Energen and its affiliates are, from time to time, parties to various pending or threatened legal proceedings. Certain of these lawsuits include claims for punitive damages in addition to other specified relief. Based upon information presently available, and in light of available legal and other defenses, contingent liabilities arising from threatened and pending litigation are not considered material in relation to the respective financial positions of Energen and its affiliates. It should be noted, however, that Energen and its affiliates conduct business in Alabama and other jurisdictions in which the magnitude and frequency of punitive damage awards may bear little or no relation to culpability or actual damages, thus making it increasingly difficult to predict litigation results. In January 2005, a lawsuit was tried in Cochran County, Texas in which the plaintiff alleged preferential purchase right claims against Energen Resources with respect to certain properties acquired by Energen Resources in 2002. The Jury rendered a verdict in Energen Resources' favor on all counts. Subsequently, in March 2005, the Judge issued a decision overruling the jury verdict. Under the Judge's order, Energen Resources would incur a charge to income of approximately $1.8 million pretax as of March 31, 2005. This amount includes the net cash flows attributable to the property since its acquisition. Energen Resources is pursuing an appeal of the Judge's order and expects to prevail. Various other pending or threatened legal proceedings arising in the normal course of business are in progress currently, and the Company has accrued a provision for estimated costs. Environmental Matters: Various environmental laws and regulations apply to the operations of Energen Resources and Alagasco. Historically, the cost of environmental compliance has not materially affected the Company's financial position, results of operations or cash flows and is not expected to do so in the future; however, new regulations, enforcement policies, claims for damages or other events could result in significant unanticipated costs. Environmental compliance costs, including ongoing maintenance, monitoring and similar costs, are expensed as incurred. Environmental remediation costs are accrued when remedial efforts are probable and the cost can be reasonably estimated. Alagasco is in the chain of title of nine former manufactured gas plant sites (four of which it still owns) and five manufactured gas distribution sites (one of which it still owns). An investigation of the sites does not indicate the present need for remediation activities. Management expects that, should remediation of any such sites be required in the future, Alagasco's share, if any, of such costs will not materially affect the financial position, results of operations or cash flows of Alagasco.

12. EQUITY AND DEBT OFFERINGS In November 2004, Energen issued $100 million of Floating Rate Senior Notes (Senior Notes) due November 15, 2007. The interest rate is the three-month LIBOR Rate plus .35%, reset quarterly. At March 31, 2005, the interest rate was 3.14 percent on the Senior Notes. In January 2005, Alagasco issued $40 million of long-term debt with an interest rate of 5.2 percent due January 15, 2020 and $40 million of long-term debt with an interest rate of 5.7 percent due January 15, 2035. The Senior Note proceeds were used for general corporate purposes and to repay a portion of short-term debt incurred to finance the oil and gas property acquisition program of Energen Resources. Alagasco used long-term debt proceeds to repay amounts drawn on short-term credit facilities for capital expenditures and to refinance $30 million in Medium-Term Notes recalled by Alagasco in April 2004. In July 2004, Energen and Alagasco increased their short-term credit lines available for working capital needs to $287 million. Alagasco has been authorized by the APSC to borrow up to a total of $100 million of these available short-term credit lines. 13. RECENT PRONOUNCEMENTS OF THE FINANCIAL ACCOUNTING STANDARDS BOARD (FASB) The Company prospectively adopted the fair value recognition provisions of SFAS No. 123 (as amended), which provided methods of transition for a voluntary change to the fair value base method of accounting for stock-based employee compensation, effective January 1, 2003. In December 2004, the FASB issued SFAS No. 123 (revised 2004), "Share-Based Payment," which requires the fair value base method of accounting for all public entities using an option-pricing model that reflects the specific economics of a company's transactions. This statement is effective for the first annual reporting period beginning after June 15, 2005. The Company is currently reviewing the impact of this pronouncement on stock-based compensation. In December 2004, the FASB issued FSP No. 109-1, "Application of SFAS No. 109, Accounting for Income Taxes, to the provision within the American Jobs Creation Act of 2004 (the Act) that provides a tax deduction on qualified production activities." This Act includes a tax deduction of up to 9 percent (when fully phased-in) of the lesser of (a) qualified production activities income as defined in the Act, or (b) taxable income of the Company determined without regard to this deduction. This tax deduction would apply to qualified production activities of Energen Resources and would be limited to 50 percent of W-2 wages paid by the Company. Pursuant to FSP No. 109-1, the deduction will be reported in the period in which the deduction is claimed on the Company's tax return and will not have an effect on deferred tax assets or deferred tax liabilities. The Company estimates the impact of this tax legislation will reduce income tax expense by approximately $1.2 million during 2005. During April 2005, the FASB issued FSP No. 19-1, "Accounting for Suspended Well Costs," which allows exploratory wells to be capitalized when the well has a sufficient quantity of reserves to justify its completion as a producing well and the enterprise is making sufficient progress assessing the reserves and the economic and operating viability of the project. This interpretation is effective for the first reporting period beginning after April 4, 2005. The impact of this position on the Company is expected to be immaterial. In March 2005, the FASB issued FIN No. 47, "Accounting for Conditional Asset Retirement Obligations", which refers to a legal obligation to perform an asset retirement activity in which the timing and (or) method of settlement are conditional on a future event that may or may not be within the control of the entity. The Company does not anticipate this interpretation to have an impact on the Company.

14. ACQUISITION OF OIL AND GAS PROPERTIES

On August 2, 2004, Energen Resources completed a purchase of San Juan Basin coalbed methane properties from a private company for approximately $273 million. The effective date of the acquisition was August 1, 2004. Energen Resources acquired an estimated 245 Bcfe of proved natural gas and natural gas liquids reserves. Approximately 51 percent of the proved reserves were estimated to be behind pipe and undeveloped. The Company estimates approximately 80 percent of the acquisition reserves are gas with natural gas liquids comprising the balance. Energen used its short-term credit facilities and internally generated cash flows to finance the acquisition. A portion of the short-term debt incurred to finance the acquisition was repaid when Energen issued $100 million of Floating Rate Senior Notes in November 2004.

Summarized below are the consolidated results of operations for the three months ended March 31, 2004, on an unaudited pro forma basis as if the purchase of assets had occurred at the beginning of the period presented. The pro forma information is based on the Company's consolidated results of operations for the three months ended March 31, 2004, and on the data provided by the seller. The pro forma financial information does not purport to be indicative of results of operations that would have occurred had the transaction occurred on the basis assumed above, nor are they indicative of results of the future operations of the combined enterprises.

15. SUBSEQUENT EVENT

On April 27, 2005, Energen's shareholders approved a 2-for-1 split of the Company's common stock. The split will be effected in the form of a 100 percent stock dividend and will be payable on June 1, 2005, to shareholders of record on May 13, 2005. Summarized below are diluted and basic average common shares outstanding and diluted and basic earnings per share on an unaudited pro forma basis for the three months ended March 31, 2005 and 2004 as if the stock dividend had been applied retroactively. Since the stock split is not effective prior to the filing of these financial statements on Form 10-Q, the share and per share amounts included elsewhere herein have not been adjusted to reflect the stock split. Such retroactive adjustment of all share and per share amounts will occur in future filings. Effective April 29, 2005, the Restated Certificate of Incorporation of Energen Corporation was amended to increase the Company's authorized common stock, par value $0.01 per share, from 75,000 ,000 shares to 150,000,000 shares.

ITEM 2.MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Energen's net income totaled $59 million ($1.60 per diluted share) for the three months ended March 31, 2005 compared with net income of $60.2 million ($1.65 per diluted share) for the same period in the prior year. Income from discontinued operations generated $105,000 in the current quarter as compared with minimal income in the prior-year first quarter. Energen Resources Corporation, Energen's oil and gas subsidiary, had net income for the three months ended March 31, 2005, of $19.6 million compared with $23.2 million in the same quarter in the previous year. Energen Resources generated net income from continuing operations of $19.5 million in the current quarter as compared with $23.2 million in the same quarter last year. Higher commodity prices of approximately $2 million after-tax and increased production volumes of approximately $2 million after-tax were more than offset by increased lease operating expenses of approximately $3 million after-tax, higher production taxes of approxim ately $1 million after-tax, increased depreciation, depletion and amortization (DD&A) expense of approximately $1 million after-tax and increased administrative expenses of approximately $2 million after-tax. Energen's natural gas utility, Alagasco, reported net income of $39 million in the first quarter of 2005 and compared favorably to net income of $36.3 million in the same period last year reflecting the utility's ability to earn on a higher level of equity.

Oil and Gas Operations

Revenues from oil and gas operations rose 7.1 percent to $102.9 million for the three months ended March 31, 2005, largely as a result of increased commodity prices as well as the impact of higher gas and natural gas liquids production volumes. During the current quarter, average gas prices fell 3.4 percent to $4.60 per thousand cubic feet (Mcf), while average oil prices rose 18.5 percent to $32.12 per barrel. Natural gas liquids prices increased 30.8 percent to an average price of $0.51 per gallon. The average gas sales price included a $9.4 million after-tax loss from the effects of open derivative contracts marked-to-market in the current quarter. These gas contracts did not meet the definition of cash flow hedges, as more fully described below.

Production increased primarily due to volumes related to the purchase of San Juan Basin coalbed methane properties and additional drilling of coalbed methane wells in the Black Warrior Basin. Energen Resources acquired an estimated 245 Bcfe of proved natural gas and natural gas liquids reserves in the San Juan Basin effective August 1, 2004. Negatively affecting production were normal declines in the Permian Basin in excess of new production coming on-line. Natural gas production from continuing operations in the first quarter rose 7.1 percent to 14.7 billion cubic feet (Bcf), oil volumes decreased 6.3 percent to 819 thousand barrels (MBbl) and natural gas liquids production increased 3.6 percent to 15.8 million gallons (MMgal). Natural gas comprised approximately 65 percent of Energen Resources' production for the current quarter.

Energen Resources periodically enters into derivative commodity instruments that qualify as cash flow hedges under Statement of Financial Accounting Standard (SFAS) No. 133, "Accounting for Derivative Instruments and Hedging Activities," to hedge its exposure to price fluctuations on oil, natural gas and natural gas liquids production. Such instruments may include regulated natural gas and crude oil futures contracts traded on the New York Mercantile Exchange (NYMEX) and over-the-counter swaps, collars and basis hedges with major energy derivative product specialists. These hedge transactions are pursuant to standing authorizations by the Board of Directors, which do not permit speculative positions.

Energen Resources applies SFAS No. 133 which requires all derivatives to be recognized on the balance sheet and measured at fair value. If a derivative is designated as a cash flow hedge, the effectiveness of the hedge, or the degree that the gain (loss) for the hedging instrument offsets the loss (gain) on the hedged item is measured at each reporting period. The effective portion of the gain or loss on the derivative instrument is recognized in other comprehensive income (OCI) as a component of equity and subsequently reclassified into earnings as operating revenues when the forecasted transaction affects earnings. The ineffective portion of a derivative's change in fair value is required to be recognized in earnings immediately. Derivatives that do not qualify for hedge treatment under SFAS No. 133 must be recorded at fair value with gains or losses recognized in operating revenues in the period of change. Energen Resources recorded an after-tax loss of $9.7 million for the current quar ter on open and closed contracts that did not meet the definition of cash flow hedges under SFAS No. 133. For the three months ended March 31, 2005, the Company recorded a $1.2 million after-tax loss for the ineffective portion of the change in fair value of derivatives accounted for as cash flow hedges.

Energen Resources has entered into the following transactions for the remainder of 2005 and subsequent years:

Realized prices are anticipated to be lower than NYMEX prices due to basis differences and other factors.

Operations and maintenance (O&M) expense increased $7.9 million for the quarter. Lease operating expenses (excluding production taxes) increased by $4.9 million for the quarter primarily due to increased workover and maintenance expenses, increased ad valorem taxes and the acquisition of San Juan Basin coalbed methane properties. Administrative expense rose $2.9 million for the three months ended March 31, 2005, primarily due to labor related costs. Exploration expense was higher by $0.3 million in quarter comparisons.

Energen Resources' DD&A expense for the quarter increased $1.9 million. The average depletion rate for the current quarter was $0.94 per mcfe as compared to $0.88 per mcfe in the same period a year ago largely due to the purchase of San Juan Basin coalbed methane properties.

Energen Resources' expense for taxes other than income taxes primarily reflected production-related taxes that were $2 million higher this quarter largely due to increased commodity market prices and increased production related to the prior year property acquisition.

Energen Resources may, in the ordinary course of business, be involved in the sale of developed or undeveloped properties. With respect to developed properties, sales may occur as a result of, but not limited to, disposing of non-strategic or marginal assets and accepting offers where the buyer gives greater value to a property than does Energen Resources. The Company is required to reflect gains and losses on the dispositions of these assets, the writedown of certain properties held-for-sale, and income or loss from the operations of the associated held-for-sale properties as discontinued operations under the provisions of SFAS No. 144, "Accounting for Impairment or Disposal of Long-Lived Assets." In the current quarter, Energen Resources recorded a pre-tax gain of $198,000 primarily from a property sale located in the Permian Basin. Energen Resources had no property sales during the three months ended March 31, 2004.

Natural Gas Distribution

Natural gas distribution revenues increased $2.9 million for the quarter largely due to an increase in the commodity cost of gas partially offset by a decrease in weather related sales volumes. Weather that was 13.6 percent warmer than in the same period last year contributed to a 13.9 percent decline in residential sales volumes and a 12.5 percent decrease in small commercial and industrial customer sales volumes. Transportation volumes decreased 5.9 percent in period comparisons. Decreased gas purchase volumes partially offset by higher gas costs contributed to a 1.3 percent decrease in cost of gas for the quarter. Utility gas costs include commodity cost, risk management gains and losses and the provisions of the GSA rider. The GSA rider in Alagasco's rate schedule provides for a pass-through of gas price fluctuations to customers without markup. Alagasco's tariff provides a temperature adjustment to certain customers' bills designed to substantially remove the effect of departures from normal temperatures. The temperature adjustment applies primarily to residential, small commercial and small industrial customers.

As discussed more fully in Note 3, Alagasco is subject to regulation by the Alabama Public Service Commission (APSC). On June 10, 2002, the APSC issued an order to extend Alagasco's rate-setting mechanism. Under the terms of that extension, RSE will continue after January 1, 2008, unless, after notice to Alagasco and a hearing, the Commission votes to either modify or discontinue its operation.

O&M expense decreased 2.7 percent in the current quarter primarily due to lower weather-related costs. An 8.4 percent increase in depreciation expense in the current quarter was due to normal replacement of the utility's distribution and support systems. Taxes other than income taxes primarily reflected various state and local business taxes as well as payroll-related taxes. State and local business taxes generally are based on gross receipts and fluctuate accordingly.

Non-Operating Items

Interest expense for the Company increased $1.4 million in the first quarter primarily due to the issuance of $100 million of Floating Rate Senior Notes by Energen in November 2004 as well as Alagasco's issuance of $40 million

of long-term debt with an interest rate of 5.2 percent and $40 million of long-term debt with an interest rate of 5.7 percent in January 2005. These increases were partially offset by interest on $30 million of Medium-Term Notes that were called in April 2004 by Alagasco. In the current quarter, income tax expense for the Company decreased $0.7 million largely due to lower consolidated pre-tax income.

FINANCIAL POSITION AND LIQUIDITY

Cash flows from operations for the year-to-date were $154.4 million as compared to $135.6 million. Operating cash flow benefited from higher realized commodity prices and production volumes at Energen Resources. The Company's working capital needs were also impacted by current liabilities associated with Energen Resources' hedge position and other changes in working capital items, which are highly influenced by throughput, changes in weather, and timing of payments. Working capital needs at Alagasco were primarily affected by increased gas costs compared to the prior period.

The Company had a net outflow of cash from investing activities of $46 million for the three months ended March 31, 2005 primarily due to additions of property, plant and equipment. Energen Resources invested $40.5 million in capital expenditures primarily related to the development of oil and gas properties. Utility capital expenditures totaled $14.6 million in the year-to-date and primarily represented system distribution expansion and support facilities.

The Company used $62.5 million for financing activities in the year-to-date primarily due to the repayment of short-term borrowings and dividends paid to common stockholders. Also influencing financing activities were the proceeds from the issuance of $80 million of long-term debt by Alagasco in January 2005.

FUTURE CAPITAL RESOURCES AND LIQUIDITY

The Company plans to continue to implement its diversified growth strategy that focuses on expanding Energen Resources' oil and gas operations through the acquisition of producing properties with developmental potential while maintaining the strength of the Company's utility foundation. For the five years ended December 31, 2004, Energen's diluted EPS grew at an average compound rate of 17.5 percent a year. Over the next five years, Energen is targeting an average diluted EPS growth rate over each rolling five-year period of approximately 7 to 8 percent a year.

Energen Resources' capital investment for oil and gas activities over a five-year planning period ending December 31, 2009, is estimated to be approximately $1.5 billion, with $1.3 billion for property acquisitions and related development, $235 million for other development and $25 million for exploratory and other activities. To finance Energen Resources' investment program, the Company expects primarily to utilize short-term credit facilities to supplement internally generated cash flow. The Company may also periodically issue long-term debt and equity to replace short-term obligations, enhance liquidity and provide for permanent financing. Energen has available short-term credit facilities aggregating $287 million to help finance its growth plans and operating needs. As more fully discussed above, the Company issued $100 million of long-term debt in November 2004. These proceeds were used for general corporate purposes and to repay a portion of short-term debt incurred to finance the oi l and gas property acquisition program of Energen Resources.

In 2005, Energen Resources plans to invest approximately $347 million in capital expenditures, including $200 million in property acquisitions, $7 million in related acquisition development and $140 million in other development and exploratory activities. As of December 31, 2004, the estimated amount of development of previously identified proved undeveloped reserves was approximately $84 million. Capital investment at Energen Resources in 2006 is expected to approximate $215 million for property acquisitions, $37 million for related acquisition development and $55 million for other development and exploration. Of this $55 million, development of previously identified proved undeveloped reserves is estimated to be $30 million and exploratory exposure is estimated to be $3 million.

Energen Resources currently expects production to approximate 94 Bcfe and 100 Bcfe for 2005 and 2006, respectively. The Company's most recent estimate of production attributable to already owned proved reserves was prepared as of December 31, 2004. Production from proved reserves owned as of December 31, 2004, was estimated as 91 Bcfe and 88 Bcfe for 2005 and 2006, respectively.

Energen Resources' continued ability to invest in property acquisitions will be influenced significantly by industry trends, as the producing property acquisition market historically has been cyclical. Notwithstanding the estimated expenditures mentioned above, as an acquisition oriented company, Energen Resources continually evaluates acquisition opportunities which arise in the marketplace and from time to time may pursue acquisitions that meet Energen's acquisition criteria which could result in capital expenditures different than those outlined above. These acquisitions or negotiations to sell, trade or otherwise dispose of properties may alter the aforementioned financing requirements.

Alagasco maintains an investment in storage gas that is expected to average approximately $54 million in 2005 but may vary depending upon the price of natural gas. During 2005 and 2006, Alagasco plans to invest approximately $59 million and $57 million, respectively, in utility capital expenditures for normal distribution and support systems. Over the Company's five-year planning period ending December 31, 2009, Alagasco anticipates capital investments of approximately $293 million. The utility anticipates funding these capital requirements through internally generated capital and the utilization of short-term credit facilities. In January 2005, Alagasco issued $80 million in long-term debt to repay amounts drawn on short-term credit facilities for capital expenditures and to refinance the $30 million in Medium-Term Notes recalled by Alagasco in April 2004. Alagasco also may refinance existing long-term debt.

Energen Resources periodically enters into derivative commodity instruments that qualify as cash flow hedges under SFAS No. 133 to hedge its exposure to price fluctuations on oil, natural gas and natural gas liquids production. In addition, Alagasco periodically enters into cash flow derivative commodity instruments to hedge its exposure to price fluctuations on its gas supply. Such instruments may include regulated natural gas and crude oil futures contracts traded on the New York Mercantile Exchange (NYMEX) and over-the-counter swaps, collars and basis hedges with major energy derivative product specialists. The counterparties to the commodity instruments are investment banks and energy-trading firms. In some contracts, the amount of credit allowed before collateral must be posted for out-of-the-money hedges varies depending on the credit rating of the Company or Alagasco. In cases where this arrangement exists, generally the credit ratings must be maintained at investment grade status t o have available counterparty credit.

Access to capital is an integral part of the Company's business plan. The Company regularly provides information to corporate rating agencies related to current business activities and future performance expectations. Standard & Poor's (S&P) has requested to meet with the Company to review such information during the second quarter. S&P currently has an A- corporate credit rating with a negative outlook for both Alagasco and Energen. While the Company expects to have ongoing access to its short-term credit facilities and the broader long-term markets, continued access could be adversely affected by future economic and business conditions and credit rating downgrades.

On April 27, 2005, Energen's shareholders approved a 2-for-1 split of the Company's common stock. The split will be effected in the form of a 100 percent stock dividend and will be payable on June 1, 2005, to shareholders of record on May 13, 2005. Since the stock split is not effective prior to the filing of these financial statements on Form 10-Q, the share and per share amounts included elsewhere herein have not been adjusted to reflect the stock split. Such retroactive adjustment of all share and per share amounts will occur in future filings.

Contractual Cash Obligations and Other Commitments

In the course of ordinary business activities, Energen enters into a variety of contractual cash obligations and other commitments. The following table summarizes the Company's significant contractual cash obligations, other than hedging contracts as of March 31, 2005.

	Payments Due before December 31,

Total contractual cash obligations	$ 1,449,990	$ 88,528	$ 304,966	$ 173,537	$ 882,959

(1) Long-term cash obligations include $1.5 million of unamortized debt discounts as of March 31, 2005. (2) Includes interest on fixed rate debt and an estimate of adjustable rate debt. The adjustable rate interest is calculated based on the indexed rate in effect at March 31, 2005. (3) Certain of the Company's long-term gas procurement contracts for the supply, storage and delivery of natural gas include fixed charges of approximately $249.7 million through October 2013. The Company also is committed to purchase minimum quantities of gas at market-related prices or to pay certain costs in the event the minimum quantities are not taken. These purchase commitments are approximately 110.5 Bcf through December 2014. Energen Resources operates in certain instances through joint ventures under joint operating agreements. Typically, the operator under a joint operating agreement enters into contracts, such as drilling contracts, for the benefit of all joint venture partners. Through the joint operating agreement, the non-operators reimburse, and in some cases advance, the funds necessary to meet the contractual obligations entered into by the operator. These obligations are typically shared on a working interest basis as defined in the joint operating contractual agreement. The Company has two defined non-contributory pension plans and provides certain post-retirement healthcare and life insurance benefits. The Company is not required to make any funding payments during 2005 for the pension plans and does not currently plan to make discretionary contributions. The Company expects to make discretionary payments of $2.6 million to post-retirement benefit program assets during the remainder of 2005. Recent Pronouncements of the Financial Accounting Standards Board (FASB) The Company prospectively adopted the fair value recognition provisions of SFAS No. 123 (as amended), which provided methods of transition for a voluntary change to the fair value base method of accounting for stock-based employee compensation, effective January 1, 2003. In December 2004, the FASB issued SFAS No. 123 (revised 2004), "Share-Based Payment," which requires the fair value base method of accounting for all public entities using an option-pricing model that reflects the specific economics of a company's transactions. This statement is effective for the first annual reporting period beginning after June 15, 2005. The Company is currently reviewing the impact of this pronouncement on stock-based compensation. In December 2004, the FASB issued FSP No. 109-1, "Application of SFAS No. 109, Accounting for Income Taxes, to the provision within the American Jobs Creation Act of 2004 (the Act) that provides a tax deduction on qualified production activities." This Act includes a tax deduction of up to 9 percent (when fully phased-in) of the lesser of (a) qualified production activities income as defined in the Act, or (b) taxable income of the Company determined without regard to this deduction. This tax deduction would apply to qualified production activities of Energen Resources and would be limited to 50 percent of W-2 wages paid by the Company. Pursuant to FSP No. 109-1, the deduction will be reported in the period in which the deduction is claimed on the Company's tax return and will not have an effect on deferred tax assets or deferred tax liabilities. The Company estimates the impact of this tax legislation will reduce income tax expense by approximately $1.2 million during 2005. During April 2005, the FASB issued FSP No. 19-1, "Accounting for Suspended Well Costs," which allows exploratory wells to be capitalized when the well has a sufficient quantity of reserves to justify its completion as a producing well and the enterprise is making sufficient progress assessing the reserves and the economic and operating viability of the project. This interpretation is effective for the first reporting period beginning after April 4, 2005. The impact of this position on the Company is expected to be immaterial. In March 2005, the FASB issued FIN No. 47, "Accounting for Conditional Asset Retirement Obligations", which refers to a legal obligation to perform an asset retirement activity in which the timing and (or) method of settlement are conditional on a future event that may or may not be within the control of the entity. The Company does not anticipate this interpretation to have an impact on the Company. Forward-Looking Statements and Risk Factors Certain statements in this report express expectations of future plans, objectives and performance of the Company and its subsidiaries and constitute forward-looking statements made pursuant to the Safe Harbor provision of the Private Securities Litigation Reform Act of 1995. Except as otherwise disclosed, the forward-looking statements do not reflect the impact of possible or pending acquisitions, divestitures or restructurings. The absence of errors in input data, calculations and formulas used in estimates, assumptions and forecasts cannot be guaranteed. Neither the Company nor Alagasco undertakes any obligation to correct or update any forward-looking statements whether as a result of new information, future events or otherwise. All statements based on future expectations rather than on historical facts are forward-looking statements that are dependent on certain events, risks and uncertainties that could cause actual results to differ materially from those anticipated. Some of these include, but are not limited to, economic and competitive conditions, inflation rates, legislative and regulatory changes, financial market conditions, our ability to access the capital markets, future business decisions, utility customer growth and retention and usage per customer, litigation results 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. The total amount or timing of actual future production may vary significantly from reserve and production estimates. In the event Energen Resources is unable to fully invest its planned acquisition, development and exploratory expenditures, future operating revenues, production, and proved reserves could be negatively affected. The drilling of development and exploratory wells can involve significant risks, including those related to timing, success rates and cost overruns, and these risks can be affected by lease and rig availability, complex geology and other factors. Although Energen Resources makes use of futures, swaps and fixed-price contracts to mitigate price risk, fluctuations in future oil and gas prices could materially affect the Company's financial position and results of operations and cash flows; furthermore, such risk mitigation activities may cause the Company's financial position and results of operations to be materially different from results that would have been obtained had such risk mitigation activities not occurred. The effectiveness of such risk-mitigation assumes that counterparties maintain satisfactory credit quality. The effectiveness of such risk mitigation also assumes that actual sales volumes will generally meet or exceed the volumes subject to the futures, swaps and fixed price contracts. A substantial failure to meet sales volume targets, whether caused by miscalculations, weather events, natural disaster, accident, criminal act or otherwise, could leave Energen Resources financially exposed to its counterparties and re sult in material adverse financial consequences to Energen Resources and the Company. The adverse effect could be increased if the adverse event was widespread enough to move market prices against Energen Resources' position. Similarly, although Alagasco makes use of futures, swaps and fixed-price contracts to mitigate gas supply cost risk, fluctuations in future gas supply costs could materially affect its financial position and rates to customers. The effectiveness of Alagasco's risk mitigation assumes that its counterparties in such activities maintain satisfactory credit quality. The effectiveness of such risk mitigation also assumes that Alagasco's actual gas supply needs will generally meet or exceed the volumes subject to the futures, swaps and fixed price contracts. A substantial failure to experience projected gas supply needs, whether caused by miscalculations, weather events, natural disaster, accident, criminal act or otherwise, could leave Alagasco financially exposed to its counterparties and result in material adverse financial consequences to Alagasco and the Company. The adverse effect could be increased if the adverse event was widespread enough to move market prices against Alagasco's positio n. Inherent in gas distribution activities are a variety of hazards and operation risks, such as leaks, explosions and mechanical problems that could cause substantial financial losses. In addition, these risks could result in loss of human life, significant damage to property, environmental pollution, impairment of our operations and substantial losses to the Company. In accordance with customary industry practices we maintain insurance against some, but not all, of these risks and losses. The location of pipeline and storage facilities near populated areas, including residential areas, commercial business centers and industrial sites, could increase the level of damages resulting from these risks. The occurrence of any of these events could adversely affect Alagasco's and the Company's financial position, results of operations and cash flows. Our utility customers are geographically concentrated in central and north Alabama. Significant economic, weather or other events that adversely affec t this region could adversely affect Alagasco and the Company.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Energen Resources' major market risk exposure is in the pricing applicable to its oil and gas production. Historically, prices received for oil and gas production have been volatile because of seasonal weather patterns, world and national supply-and-demand factors and general economic conditions. Crude oil prices also are affected by quality differentials, by worldwide political developments and by actions of the Organization of Petroleum Exporting Countries. Basis differentials, like the underlying commodity prices, can be volatile because of regional supply-and-demand factors, including seasonal factors and the availability and price of transportation to consuming areas.

Energen Resources periodically enters into derivative commodity instruments that qualify as cash flow hedges under Statement of Financial Accounting Standard (SFAS) No. 133, "Accounting for Derivative Instruments and Hedging Activities," to hedge its exposure to price fluctuations on oil, natural gas and natural gas liquids production. In addition, Alagasco periodically enters into cash flow derivative commodity instruments to hedge its gas supply exposure. Such instruments may include regulated natural gas and crude oil futures contracts traded on the New York Mercantile Exchange (NYMEX) and over-the-counter swaps, collars and basis hedges with major energy derivative product specialists. The counterparties to the commodity instruments are investment banks and energy-trading firms. These counterparties have been deemed creditworthy by the Company and have agreed in certain instances to post collateral with the Company when unrealized gains on hedges exceed certain specified contractual am ounts. Notwithstanding these agreements, the Company is at risk for economic loss based upon the creditworthiness of its counterparties. In some contracts, the amount of credit allowed before Energen Resources and Alagasco must post collateral for out-of-the-money hedges varies depending on the credit rating of the Company or Alagasco. All hedge transactions are subject to the Company's risk management policy, approved by the Board of Directors, which does not permit speculative positions. The Company formally documents all relationships between hedging instruments and hedged items, as well as its risk management objective and strategy for undertaking the hedge. The maximum term over which Energen Resources has hedged exposures to the variability of cash flows is through December 31, 2006.

See Note 4 for details related to the Company's hedging activities.

Any directorship to be filled by reason of an increase in the number of directors shall be filled by election at an annual meeting or at a special meeting of stockholders called for that purpose, unless applicable law then permits such directorship to be filled by the affirmative vote of a majority of the remaining directors (even though less than a quorum of the Board of Directors). No decrease in the number of directors constituting the Board of Directors shall shorten the term of any incumbent director.

(a) Subject to Section 9.06 of Article IX and paragraph (e) of Section 10.01 hereof, to make, alter and repeal Bylaws of the Corporation, subject to the power of the stockholders to alter or repeal Bylaws made by the Board of Directors, which action by the directors shall fully protect third parties in dealing with the Corporation; provided, however, that the Board of Directors may not alter, amend or repeal any Bylaw establishing what constitutes a quorum at any meeting of the stockholders of the Corporation;

(b) To determine, subject to the provisions of Article IX hereof, whether any, and if any, what part, of the net income of the Corporation or of its net assets in excess of its capital shall be declared in dividends and paid to the stockholders and whether or not in cash or capital stock of the Corporation or in other property, and generally to determine and direct the use and disposition of any such net income or any such excess of net assets over capital; and to fix the times for the declaration and payment of dividends;

(c) From time to time, to fix the amount to be reserved over and above the capital stock of the Corporation paid in and to determine and direct how amount so reserved shall be used;

(e) From time to time, and without other limit as to amount, except as may be provided in a resolution or resolutions adopted by the stockholders of the Corporation, to borrow or otherwise raise moneys for any of the purposes of the Corporation; to authorize the issue of bonds, debentures, notes, or other obligations of the Corporation, of any nature, or in any manner, and to authorize the creation of mortgages upon, or the pledge or conveyance or assignment in trust of, the whole or any part of the property of the Corporation, real or personal, whether at the time owned or thereafter acquired, including contract rights, to secure the payment of any of such bonds, debentures, notes or other obligations and the interest thereon; and to authorize the sale or pledge or other disposition of such bonds, debentures, notes or other obligations of the Corporation for its corporate purposes;

(f) To provide, subject to the requirements of law and the bylaws of the Corporation, for the holding of stockholders and Directors meetings within or without the State of Alabama at such places as may be from time to time designated by resolution of the Board of Directors and to provide for an office or offices and for the keeping of the books of the Corporation (subject to the provisions of the statute) within or without the State of Alabama;

(g) By resolution adopted by majority vote of all the Directors of the Corporation as at the time fixed by its bylaws, to designate three or more of their number to constitute an executive committee, which, to the extent provided in such resolution or in the bylaws of the Corporation, shall have and may exercise the powers of the Board of Directors in the management of the business and affairs of the Corporation, and may have power to authorize the seal of the Corporation to be affixed to all papers which may require it, and by like resolution, from time to time, to constitute other committees out of their number, with such powers as shall be provided in such resolutions or in the bylaws of the Corporation;

(h) Any action required or permitted to be taken at any meeting of the Board of Directors or any committee thereof may be taken without a meeting, if prior to such action a written consent thereto is signed by all members of the Board or such committee, as the case may be, and such written consent is filed with the minutes of proceedings of the Board or committee;

(i) To exercise such further powers as may be conferred by the bylaws of the Corporation in addition to the powers and authority expressly conferred in the foregoing or by law.

XI. Limitation of Liability:

11.01 A director of the Corporation shall not be liable to the Corporation or its shareholders for money damages for any action taken, or failure to take action, as a director, except for (i) the amount of a financial benefit received by such director to which such director is not entitled; (ii) an intentional infliction of harm by such director on the Corporation or its shareholders; (iii) a violation of Section 10-2B-8.33 of the Code of Alabama of 1975 or any successor provision to such section; (iv) an intentional violation by such director of criminal law; or (v) a breach of such director's duty of loyalty to the Corporation or its shareholders. If the Alabama Business Corporation Act, or any successor statute thereto, is hereafter amended to authorize the further elimination or limitation of the liability of a director of a corporation, then the liability of a director of the Corporation, in addition to the limitations on liability provided herein, shall be limited to the fullest e xtent permitted by the Alabama Business Corporation Act, as amended, or any successor statute thereto. The limitation on liability of directors of the Corporation contained herein shall apply to liabilities arising out of acts or omissions occurring subsequent to the adoption of this Article XI and, except to the extent prohibited by law, to liabilities arising out of acts or omissions occurring prior to the adoption of this Article XI. Any repeal or modification of this Article XI by the shareholders of the Corporation shall be prospective only and shall not adversely affect any limitation on the liability of a director of the Corporation existing at the time of such repeal or modification.
