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

1. BASIS OF PRESENTATION The unaudited condensed 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 Company's natural gas distribution business is seasonal in character and influenced by weather conditions. Results o f 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 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. During the quarter ended September 30, 2005, the Company reduced Treasury Stock and Deferred Compensation Plan, both reflected in shareholders' equity, by $25 million to correct the carrying value of the equity-based deferred compensation previously reported at market value to historical cost as prescribed by the Emerging Issues Task Force No. 97-14, "Accounting for Deferred Compensation Arrangements Where Amounts Earned Are Held in a Rabbi Trust and Invested."  This change had no impact on current or previously reported net income, cash flows or total shareholders' equity. 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 proforma net income for the three months and nine months ended September 30, 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:

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. As of September 30, 2005, Alagasco had a $3.3 million reduction in revenues to bring the return on average equity to midpoint within the allowed range of return. Alagasco did not have a reduction in rates related to the return on average equity for the rate year ended 2004. 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 under the provisions of RSE. Alagasco's O&M expense fell within the index range for the rate year ended September 30, 2005. 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. At September 30, 2005, the Company had $1.8 million posted in collateral payments with a certain counterparty. 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 September 30, 2005, $148.1 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 amount 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 million after-tax loss for the three months ended September 30, 2005, and a $3 million after-tax loss year-to-date. Also, Energen Resources recorded an after-tax loss of $11.1 million for the qu arter and a $16.7 million after-tax loss year-to-date on contracts that did not meet the definition of cash flow hedges under SFAS No. 133. As of September 30, 2005, the Company had 2.9 billion cubic feet (Bcf) of gas hedges with a fair value after-tax loss of $11.4 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. In the current year-to-date, the Company discontinued hedge accounting and reclassified losses of $0.9 million after-tax from OCI into operating revenues when Energen Resources determined it was probable certain forecasted transactions volumes would not occur. The Company had $106 million and $15.6 million included in current and noncurrent deferred income taxes on the consolidated balance sheets related to items included in OCI as of September 30, 2005 and December 31, 2004, respectively. At September 30, 2005, and December 31, 2004, the Company had $270 million and $40.7 million, respectively, re corded in accounts payable and $40.3 million and $3.2 million, respectively, recorded in other noncurrent liabilities related to derivative liabilities.
Energen Resources has entered into the following transactions for the remainder of 2005 and subsequent years:

* 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, 2007.

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, "Accounting for the Effects of Certain Types of Regulation," Alagasco recorded a $41.8 million and $8.1 million gain as a regulatory liability as of September 30, 2005 and December 31, 2004, respectively, with a corresponding asset in prepayments and other representing the fair value of derivatives.

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 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. 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 o f the carrying amount or fair value. In the nine months ended September 30, 2005, Energen Resources recorded a pre-tax gain of $194,000 primarily from a property sale located in the Permian Basin. Energen Resources had no property sales during the three months ended September 30, 2005 and 2004 or the year-to-date ended September 30, 2004. The following are the results of operations from discontinued operations:

For the three months and nine months ended September 30, 2005, the Company made contributions aggregating $0.8 million and $2.4 million, respectively, to the post-retirement plans. The Company expects to make additional discretionary contributions of approximately $0.8 million through the remainder of 2005.

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 $228 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 173.1 Bcf through April 2015. 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 September 30, 2005, the fixed price purchases under these guarantees had a maximum term outstanding through March 2006 and an aggregate purchase price of $2.9 million with a market value of $6.1 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. Energen Resources is pursuing an appeal of the Judge's order and expects to prevail. Under the Judge's order, Energen Resources potential pre-tax charge to income would be approximately $2.3 million as of September 30, 2005, none of which has been accrued. This amount includes the net cash flows attributable to the property since its acquisition. Alagasco is a defendant in a lawsuit filed in Jefferson County, Alabama alleging breach of contract and fraud for compensatory and punitive damages in connection with compressed natural gas vehicle services provided to Alagasco by the plaintiff. Alagasco expects to prevail in its defense of the case. As noted above, however, it is difficult to predict litigation results. In the event that the plaintiff prevails, Alagasco estimates a damage award range of $300,000 to $2,000,000, none of which has been accrued. 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. During 2004, the State of New Mexico issued new regulations related to below-grade storage pits. Such pits are used to temporarily hold produced fluids until they can be disposed of permanently. Under the new regulations, the storage pits must be constructed with secondary containment and leak detection, and all such pits will require an annual certification attesting that the storage pits do not leak. As a result of this regulation, the Company expensed $0.9 million as a lease operating expense during the nine months ended September 30, 2005. During 2004, the Company capitalized $0.5 million as part of its acquisition of properties in the San Juan Basin and expensed $1.6 million as a lease operating expense under this regulation. The Company does not anticipate any further remediation charges on existing properties related to the new regulations. 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 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 September 30, 2005, the interest rate was 4.14 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 of Medium-Term Notes called by Alagasco in April 2004. In August 2005, Alagasco called a total of $18 million of Medium-Term Notes maturing June 27, 2007 to July 5, 2022. As of September 30, 2005, Energen and Alagasco had short-term credit lines available for working capital needs up to $260 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 ACCOUNTING PRONOUNCEMENTS In December 2004, the Financial Accounting Standards Board (FASB) issued SFAS No. 123 (revised 2004), "Share-Based Payment (SFAS No. 123R)," which requires a fair value base method of accounting using pricing models that reflect 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 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. The Company will adopt SFAS No. 123R using the modified prospective application method for new awards effective January 1, 2006. The Company is currently evaluating its stock-based compensation and the application of SFAS No. 123R. 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 $0.9 million during 2005. 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. This interpretation is effective no later than the end of fiscal years ending after December 15, 2005. The impact of this interpretation on the Company is currently being evaluated.
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 and nine months ended September 30, 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 and nine months ended September 30, 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. STOCK DIVIDEND On April 27, 2005, Energen's shareholders approved a 2-for-1 split of the Company's common stock. The split was effected in the form of a 100 percent stock dividend and was payable on June 1, 2005, to shareholders of record on May 13, 2005. All share and per share amounts of capital stock outstanding have been adjusted to reflect the stock split. 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 $19.1 million ($0.26 per diluted share) for the three months ended September 30, 2005 and compared favorably with net income of $13.7 million ($0.19 per diluted share) for the same period in the prior year. Energen Resources Corporation, Energen's oil and gas subsidiary, had net income for the three months ended September 30, 2005, of $28.1 million compared with $21.7 million in the same quarter in the previous year. Energen Resources reported net income from continuing operations of $28.1 million in the current quarter as compared with $21.6 million in the same quarter last year. Significantly higher commodity prices (approximately $10 million after-tax) and increased production volumes (approximately $3 million after-tax) were partially offset by increased lease operating expenses (approximately $3 million after-tax), higher production taxes (approximately $2 million after-tax) and increased depreciation, depletion and amortization (DD&A) expense (approxi mately $2 million after-tax). Energen's natural gas utility, Alagasco, reported a net loss of $8.8 million in the third quarter of 2005 compared to a net loss of $7.7 million in the same period last year. Alagasco recognized a reduction in revenues in the current quarter to bring the return on average equity to midpoint within the utility's allowed range of return at the end of the fiscal year for rate-setting purposes (approximately $2 million after-tax). The utility historically records a net loss in the third quarter when the heating load is at its lowest level of the year.

For the 2005 year-to-date, Energen's net income totaled $115.7 million ($1.57 per diluted share) and compared favorably to net income of $96.2 million ($1.31 per diluted share) for the same period in the prior year. Energen Resources had net income for the nine months ended September 30, 2005, of $84 million as compared with $66.7 million in the previous period. Energen Resources generated income from continuing operations of $83.9 million in the current year-to-date as compared with $66.6 million in the same period last year primarily as a result of higher commodity prices (approximately $31 million after-tax) and increased production volumes (approximately $11 million after-tax) partially offset by the impact of increased lease operating expenses (approximately $11 million after-tax), higher production taxes (approximately $6 million after-tax), increased DD&A expense (approximately $5 million after-tax) and increased administrative expenses (approximately $4 million after-tax). Alag asco's net income of $31.3 million in the current year-to-date increased from net income of $29.1 million in the same period in the previous year primarily reflecting the utility's ability to earn on a higher level of equity.

Oil and Gas Operations

Revenues from oil and gas operations rose 21.2 percent to $126.3 million for the three months ended September 30, 2005, and 23 percent to $363.6 million in the year-to-date largely as a result of increased commodity prices as well as the impact of higher gas production volumes. During the current quarter, average gas prices rose 11.5 percent to $5.31 per thousand cubic feet (Mcf), while average oil prices increased 23.5 percent to $35.51 per barrel. Natural gas liquids prices increased 18 percent to an average price of $0.59 per gallon. In the year-to-date, average gas prices increased 13.1 percent to $5.39 Mcf, average oil prices rose 22.9 percent to $33.75 per barrel and natural gas liquids prices increased 22.7 percent to $0.54 per gallon. The average sales prices included an $8.6 million after-tax loss in the current quarter and an $11.4 million after-tax loss year-to-date from the effects of open gas derivative contracts marked-to-market. These gas contracts did not meet the defin ition of cash flow hedges, as more fully described below. The Company also included in the average gas and oil sales prices a $0.9 million after-tax loss for the current quarter and a $1.5 million after-tax loss year-to-date on open contracts for the ineffective portion of the change in fair value of derivatives accounted for as cash flow hedges.

Production increased primarily due to volumes related to the prior year purchase of San Juan Basin coalbed methane properties and increased drilling of wells in North Louisiana. 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 was a normal production decline that was in excess of new production coming on-line in the Permian Basin. Natural gas production from continuing operations in the third quarter rose 9.4 percent to 16 billion cubic feet (Bcf), while oil volumes fell 4.8 percent to 813 thousand barrels (MBbl) and natural gas liquids production declined slightly to 18.1 million gallons (MMgal). For the year-to-date, natural gas production increased 9.1 percent to 45.9 Bcf and oil production decreased 3 percent to 2.5 MBbl. Natural gas liquids production rose 4.4 percent to 52.5 MMgal. Natural gas comprised approximately 65 percent of Energen Resources' p roduction for the current quarter and the year-to-date.

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 $11.1 million for the three month s ended September 30, 2005, and a $16.7 million after-tax loss year-to-date on open and closed contracts that did not meet the definition of cash flow hedges under SFAS No. 133. For the three months ended September 30, 2005, the Company recorded a $1 million after-tax loss and a $3 million after-tax loss year-to-date on open and closed contracts 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 $5.7 million for the quarter and $22.2 million in the year-to-date. Lease operating expenses (excluding production taxes) increased by $5.3 million for the quarter and $17.2 million year-to-date primarily due to increased workover and maintenance expenses, increased ad valorem taxes and overall price increases related to higher commodity prices. Partially offsetting these increases were lower compliance costs related to prior year regulations for below-grade storage pits. Administrative expense rose $2.1 million for the three months ended September 30, 2005 and $6.3 million in the year-to-date, primarily due to labor related costs. Exploration expense was lower by $1.7 million in the third quarter and by $1.3 million in year-to-date comparisons.

Energen Resources' DD&A expense for the quarter increased $2.7 million and rose $8.1 million year-to-date. The average depletion rate for the current quarter was $0.98 per mcfe as compared to $0.91 per mcfe in the same period a year ago. For the nine months ended September 30, 2005, the average depletion rate was $0.96 per mcfe as compared to $0.89 per mcfe in the previous period. The increases in depletion rates were largely due to a higher depreciation rate on coalbed methane properties purchased in the prior year and to the current year production mix that reflects a higher percentage of the Company's shorter-lived North Louisiana/East Texas production.

Energen Resources' expense for taxes other than income taxes primarily reflected production-related taxes that were $3.9 million higher this quarter and $9.3 million higher year-to-date largely due to increased commodity market prices and increased production related to the prior year San Juan Basin 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 write-down 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 year-to-date, Energen Resources recorded a pre-tax gain of $194,000 primarily from a property sale located in the Permian Basin. Energen Resources had no property sales during the three months ended September 30, 2005 and 2004 or the year-to-date ended September 30, 2004.

Natural Gas Distribution

Natural gas distribution revenues increased $2.3 million for the quarter largely due to an increase in sales to commercial and industrial customers. Alagasco recognized a $3.3 million reduction in revenues in the current quarter under regulatory rate setting requirements to bring the return on average equity to midpoint in the allowed range of return. For the quarter, weather was comparable with the same period last year. Residential sales volumes declined 3.4 percent. Commercial and industrial customer sales volumes increased 14.1 percent primarily due to additional usage from co-generation plants along with increased volumes generated from new load. Transportation volumes decreased 6.6 percent in period comparisons. Revenues for the year-to-date rose $19.6 million primarily due to an increase in commodity gas costs partially offset by a decrease in weather related usage and the regulatory reduction to revenues as discussed for the quarter. Weather that was 7.8 percent warmer than in the previous period contributed to an 8.4 percent decline in residential sales volumes and a 3.5 percent decrease in commercial and industrial customer sales volumes. Large transportation volumes declined 7.2 percent. Increased gas purchase volumes resulted in a 3.2 percent increase in cost of gas for the quarter. For the year-to-date, an increase in cost of gas of 4.5 percent was largely due to higher gas costs compared to the prior period partially offset by a decline in gas purchase volumes. 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 to the Unaudited Condensed Financial Statements, 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 increased 4.5 percent in the current quarter and 2.9 percent in the nine months ended September 30, 2005, primarily due to increased bad debt expense and distribution maintenance expenses partially offset by reduced insurance costs. A 6.8 percent increase in depreciation expense in the current quarter and a 7.7 percent increase in the year-to-date 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 $1.1 million in the third quarter and $3.3 million year-to-date 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 $80 million of long-term debt in January 2005. Positively impacting interest expense was Alagasco's election to call $18 million of Medium-Term Notes in August 2005. In the year-to-date comparison, interest expense was also affected by $30 million of Medium-Term Notes that were called in April 2004 by Alagasco. In the current quarter, income tax expense for the Company increased $2.6 million and was $10.7 million higher in year-to-date comparisons largely due to higher consolidated pre-tax income. Alagasco's income tax benefit increased $0.5 million in the current quarter primarily due to a higher pre-tax loss. For the year-to-date comparison, income tax expense rose $2.2 million primarily due to higher pre-tax income.

Exposure to Natural Disaster

The Company's production properties and distribution system did not suffer significant damage from Hurricanes Katrina and Rita which occurred in the third quarter of 2005. Energen Resources experienced minimal loss of production and Alagasco had no significant supply disruptions as a result of these hurricanes. These events, however, highlight the potential for a period of production shut-in for Energen Resources resulting from a prolonged interruption of service in areas which have a concentration of fractionation plants and refineries through which a substantial portion of the Company's oil and natural gas liquids production flow. Alagasco's customer base is geographically concentrated in central Alabama. Damage to Alagasco's delivery infrastructure, Energen Resources' production infrastructure or to third party facilities which serve Alagasco and/or Energen Resources due to a natural disaster or other event could result in significant adverse financial consequences to Alagasco and/o r the Company.

FINANCIAL POSITION AND LIQUIDITY

Cash flows from operations for the year-to-date were $312.7 million as compared to $253.2 million. Operating cash flow benefited from higher realized commodity prices and production volumes at Energen Resources. The Company's working capital needs were also 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 and storage gas inventory.

The Company had a net outflow of cash from investing activities of $173.9 million for the nine months ended September 30, 2005 primarily due to additions of property, plant and equipment. Energen Resources invested $132.7 million in capital expenditures primarily related to the development of oil and gas properties. Utility capital expenditures totaled $52.9 million in the year-to-date and primarily represented system distribution expansion and support facilities.

The Company used $105.1 million for financing activities in the year-to-date primarily due to the repayment of short-term borrowings, repayments of long-term debt, including Alagasco's election to call $18 million of Medium-Term Notes in July 2005, 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 long-term, Energen is targeting an average diluted EPS growth rate over each rolling five-year period of approximately 8 percent a year.

On April 27, 2005, Energen's shareholders approved a 2-for-1 split of the Company's common stock. The split was effected in the form of a 100 percent stock dividend and was payable on June 1, 2005, to shareholders of record on May 13, 2005. All share and per share amounts of capital stock outstanding have been adjusted to reflect the stock split.

Over the five-year planning period ending December 31, 2009, Energen Resources plans to spend approximately $324 million for development on existing properties and $30 million for exploratory and other activities. 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 will pursue acquisitions that meet Energen's acquisition criteria which could result in capital expenditures different than those outlined above. The Company is prepared to invest approximately $1 billion over the next five years for property acquisitions that meet Energen's acquisition criteria. 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 li quidity and provide for permanent financing. Energen currently has available short-term credit facilities aggregating $260 million to help finance its growth plans and operating needs. Energen Resources' continued ability to invest in property acquisitions is subject to market conditions and industry trends.

In 2005, Energen Resources plans to invest approximately $168 million in capital expenditures primarily for development and exploratory activities. As of December 31, 2004, the estimated amount of 2005 development of previously identified proved undeveloped reserves was approximately $84 million. Approximately $5 million is estimated for 2005 exploratory exposure. Capital investment at Energen Resources in 2006 is expected to approximate $121 million for development and exploration. Of this $121 million, development of previously identified proved undeveloped reserves is estimated to be $30 million and exploratory exposure is estimated to be $6 million.

Energen Resources currently expects production to approximate 92 Bcfe and 89 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' lease operating expenses have significantly increased reflecting higher workover and maintenance expenses, increased taxes and other field-service-related expenses generally caused by an increased price environment. In addition, wider than anticipated basis differentials have resulted from regional supply-and-demand. The Company anticipates these price increase trends will continue in the near term.

An increase in national wholesale natural gas prices will increase natural gas costs for Alagasco customers for the 2005-2006 heating season as compared to the 2004-2005 heating season. Alagasco's rate schedules for natural gas distribution charges contain a Gas Supply Adjustment rider which permits the pass-through to customers for changes in the cost of gas supply. On October 1, 2005, Alagasco increased its rates 36.7 percent to begin recovering these increased gas costs although such increases will not have a significant impact on most customers until the winter heating season. Sustained high prices may decrease Alagasco's customer base and could result in a decline in per customer use and number of customers. The utility will continue to monitor its bad debt reserve and will make adjustments as required based on its evaluation of its receivables which are impacted by natural gas prices.

Alagasco maintains an investment in storage gas that is expected to average approximately $55 million in 2005 but will vary depending upon the price of natural gas. During 2005 and 2006, Alagasco plans to invest $69 million and $63 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 $327 million. The utility anticipates funding these capital requirements through internally generated capital and the utilization of 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 $30 million of Medium-Term Notes recalled by Alagasco in April 2004. In August 2005, Alagasco called $18 million of Medium-Term Notes maturing June 27, 2007 to July 5, 2022. During the fourth quarter of 2005, Alagasco plans to issu e $80 million in long-term debt in part to refinance the $18 million of called Medium-Term Notes. A portion of the proceeds is also expected to be used to refinance $56.7 million of notes scheduled to be called subsequent to the fourth quarter debt issuance by Alagasco.

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. At September 30, 2005, the Company had $1.8 million posted in collateral payments with a certain counterparty.

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. 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.

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 September 30, 2005.

The adjustable rate interest is calculated based on the indexed rate in effect at September 30, 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 $228 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 173.1 Bcf through April 2015. 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. The Company will reevaluate discretionary contributions in the fourth quarter of 2005 based on the annual measurement of pension obligations. The Company expects to make discretionary payments of $0.8 million to post-retirement benefit program assets during the remainder of 2005. Recent Accounting Pronouncements In December 2004, the Financial Accounting Standards Board (FASB) issued SFAS No. 123 (revised 2004), "Share-Based Payment (SFAS No. 123R)," which requires a fair value base method of accounting using pricing models that reflect 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 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. The Company will adopt SFAS No. 123R using the modified prospective application method for new awards effective January 1, 2006. The Company is currently evaluating its stock-based compensation and the application of SFAS No. 123R. 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 $0.9 million during 2005. 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. This interpretation is effective no later than the end of fiscal years ending after December 15, 2005. The impact of this interpretation on the Company is currently being evaluated. 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. Third Party Facilities: The forward looking statements also assume generally uninterrupted access to third party oil and gas gathering, transportation, processing and storage facilities. Energen Resources relies upon such facilities for access to markets for its production. Alagasco relies upon such facilities for access to natural gas supplies. Such facilities are typically limited in number and geographically concentrated. An extended interruption of access to or service from these facilities, whether caused by weather events, natural disaster, accident, mechanical failure, criminal act or otherwise could result in material adverse financial consequences to Alagasco, Energen Resources and/or the Company. Energen Resources Production: 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. Energen Resources Hedging: Although Energen Resources makes use of futures, swaps and fixed-price contracts to mitigate price risk, fluctuations in future commodity 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 expo sed to its counterparties and result 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. Alagasco Hedging: 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, mechanical failure, 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 position. Operations: Inherent in the gas distribution activities of Alagasco and the oil and gas production activities of Energen Resources 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, Energen Resources' and/or the Company's financial position, results of operations and cash flows. Alagasco Service Territory: Alagasco's utility customers are geographically concentrated in central and north Alabama. Significant economic, weather, natural disaster, criminal act or other events that adversely affect 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, 2007.

See Note 4 to the Unaudited Condensed Financial Statements for details related to the Company's hedging activities.

The Company's interest rate exposure as of September 30, 2005, was minimal since approximately 85 percent of long-term debt obligations were at fixed rates.
