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, 2007, 2006 and 2005 included in the 2007 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 of operations for interim periods are not necessarily indicative of the results that may be expected
for the year.

All 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.

2. REGULATORY MATTERS

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 in 2007, 2002, 1996, 1990, 1987 and 1985. On December 21, 2007, the APSC extended Alagascos rate-setting methodology, RSE, with certain modifications as outlined below, for a seven-year period through December 31, 2014.
Under the terms of the extension, RSE will continue after December 31, 2014, unless, after notice to the Company and a hearing, the APSC votes to either modify or discontinue the RSE methodology. Alagascos allowed range of return on
average equity remains 13.15 percent to 13.65 percent throughout the term of the order. 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, 2007, Alagasco had a $3.6 million pre-tax reduction in revenues to bring the return on average equity to midpoint within the allowed range of
return. Under the provisions of RSE, corresponding reductions in rates were effective October 1, 2007 and December 1, 2007. A $12 million and $14.3 million annual increase in revenues became effective December 1, 2007 and 2006,
respectively.

Prior to the December 21, 2007 extension, RSE limited the utilitys equity upon which a return is permitted to 60
percent of total capitalization. Subsequent to the extension, the equity on which a return will be permitted will be phased down to 57 percent by September 30, 2008 and 55 percent by September 30, 2009.

Prior to the extension, under the inflation-based Cost Control Measurement (CCM) established by the APSC, if the percentage change in operations and
maintenance (O&M) expense per customer fell 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 was required. If the change in O&M expense per
customer exceeded the Index Range, three-quarters of the difference was returned to customers. To the extent the change was less than the Index Range, the utility benefited by one-half of the difference through future rate adjustments. The changes
to the O&M expense CCM resulting from the December 21, 2007 extension are as follows: annual changes in O&M expense will be measured on an aggregate basis rather than per customer; the percentage change in O&M expense must fall
within an Index Range of 0.75 points above or below the percentage change in the Consumer Price Index for All Urban Consumers; certain items that fluctuate based on situations demonstrated to be beyond Alagascos control may be excluded from

the CCM calculation; the O&M expense base for measurement purposes will continue to be set at the prior years actual O&M expense amount unless
the Company exceeds the top of the Index Range in two successive years, in which case the base for the following year will be set at the top of the Index Range. Alagascos O&M expense fell within the Index Range for the rate year ended
September 30, 2007.

Alagasco calculates a temperature adjustment to customers monthly bills to moderate the impact 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 regulatory limitations on increases to customers bills. Other non-temperature weather related conditions that may affect customer usage are not included in the
temperature adjustment such as the impact of wind velocity or cloud cover and the elasticity of demand as a result of higher 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.

3. 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 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 exposure to price fluctuations on its gas supply. Such instruments may include natural gas and crude oil over-the-counter
(OTC) 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. At March 31, 2008, the counterparty agreements under which the Company had active positions did not include collateral posting
requirements. Energen Resources was in a net loss position with all of its counterparties at March 31, 2008. The Company believes the creditworthiness of these counterparties is satisfactory.

Energen Resources applies SFAS No. 133 as amended 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 shareholders equity and subsequently reclassified 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 operating revenues immediately. Counterparty credit risk and nonperformance risk are considered in the evaluation of the effectiveness of a hedge and in
the on-going qualification for hedge accounting treatment. Derivatives that do not qualify for hedge treatment under SFAS No. 133 are recorded at fair value with gains or losses recognized in operating revenues in the period of change. All
derivative transactions are included in operating activities on the consolidated condensed statement of cash flows.

As of March 31,
2008, $120.7 million, net of tax, of deferred net losses on derivative instruments recorded in accumulated other comprehensive income are expected to be reclassified and reported in earnings as operating revenues during the next twelve-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 hedge
transactions, 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 March 31, 2008. Also, the Company recorded an after-tax loss of approximately $0.6 million during the
first quarter of 2008 on contracts which did not meet the definition of cash flow hedges under SFAS No. 133. As of March 31, 2008, the Company had 0.87 billion cubic feet (Bcf) of gas hedges 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 maximum term over which Energen Resources has hedged exposures to the variability of cash
flows is through December 31, 2010.

Effective January 1, 2008, the Company partially adopted SFAS No. 157, Fair Value
Measurements, under the provisions of the Financial Accounting Standards Board (FASB) Staff Position 157-2, Effective Date of FASB Statement No. 157. SFAS No. 157 defines fair value, establishes a framework for measuring
fair value and expands disclosures about fair value measurements. As defined under SFAS No. 157, fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market
participants at the measurement date (exit price). SFAS No. 157 establishes a fair value hierarchy that prioritizes the inputs used to measure fair value defined as follows:



|          |  |                                                                                                                                                            
|--------- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------
|Level 1  |  | Unadjusted quoted prices in active markets for identical assets or liabilities;                                                                            
|Level 2  |  | Pricing inputs other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable as of the reporting
date;
|Level 3  |  | Pricing that requires inputs that are both significant to the fair value measure and unobservable.                                                         

Over-the-counter derivatives are valued using market transactions and other market evidence
whenever possible, including market-based inputs to models and broker or dealer quotations. These OTC derivative contracts trade in less liquid markets with limited pricing information, and the determination of fair value is inherently more
difficult than for actively traded, unadjusted quoted prices. OTC derivatives for which the Company is able to substantiate fair value through directly observable market prices are classified within Level 2 of the fair value hierarchy. These Level 2
fair values consist of New York Mercantile Exchange (NYMEX) swaps. OTC derivatives valued using unobservable market prices have been classified within Level 3 of the fair value hierarchy. These Level 3 fair values include basin specific, basis and
liquids swaps.

The Company had a net $99.5 million and a net $39.9 million deferred tax asset included in current
and noncurrent deferred income taxes on the consolidated balance sheets related to derivative items included in OCI as of March 31, 2008 and December 31, 2007, respectively.

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, at December 31,
2007, Alagasco recognized a $0.4 million loss as a liability in accounts payable with a corresponding current regulatory asset representing the fair value of derivatives. At March 31, 2008, Alagasco had no hedge positions.

7. STOCK COMPENSATION

1997 Stock Incentive Plan

Stock Options: The 1997 Stock Incentive Plan provided for the grant of incentive stock
options, non-qualified stock options, or a combination thereof to officers and key employees. Options granted under the Plan provide for the purchase of Company common stock at not less than the fair market value on the date the option is granted.
The sale or transfer of the shares is limited during certain periods. All outstanding options vest within three years from date of grant and expire 10 years from the grant date. The Company granted 186,700 non-qualified option shares during the
first quarter of 2008 with a grant-date fair value of $20.73.

2004 Stock Appreciation Rights Plan

The Energen 2004 Stock Appreciation Rights Plan provided for the payment of cash incentives measured by the long-term appreciation of Company stock. These
awards are liability awards which settle in cash and are re-measured each reporting period until settlement and have a three year vesting period. The Company granted 67,093 awards during the first quarter of 2008. These awards had a fair value of
$16.87 as of March 31, 2008.

Petrotech Incentive Plan

The Energen Resources Petrotech Incentive Plan provided for the grant of stock equivalent units. These awards are liability awards which settle in cash and are re-measured each reporting period until settlement.
During the three months ended March 31, 2008, Energen Resources awarded 1,805 Petrotech units with a two year vesting period and 1,014 Petrotech units with a three year vesting period.

1997 Deferred Compensation Plan

During the three
months ended March 31, 2008, the Company had noncash purchases of approximately $27 million of Company common stock in conjunction with tax withholdings on its non-qualified deferred compensation plan and other stock compensation. The Company
utilized internally generated cash flows in payment of the related tax withholdings.

8. EMPLOYEE BENEFIT PLANS

The Company accounts for defined benefit pension plans and other postretirement benefit plans (benefit plans) in accordance with SFAS No. 158,
Employers Accounting for Defined Benefit Pension and Other Postretirement Plans, an amendment of FASB Statements No. 87, 88, 106 and 132 (R). Periodic expense is calculated on an actuarial basis and the net funded status of
benefit plans is recognized as an asset or liability in its statement of financial position with changes in the funded status recognized through comprehensive income. For pension plans, the benefit obligation is the projected benefit obligation; for
other postretirement plans, the benefit obligation is the accumulated postretirement benefit obligation. Alagasco recognizes a regulatory asset for the portion of the obligation to be recovered in rates in future periods and a regulatory liability
for the portion of the plan obligation to be provided through rates in the future in accordance with SFAS No. 71. SFAS No. 158 requires an employer to measure the funded status of a plan as of the date of its year-end statement of
financial position effective for fiscal years ending after December 15, 2008. The Company currently uses a September 30 valuation date for its benefit plans and anticipates adopting the change in measurement date using the alternative
method. During the fourth quarter of 2008, the Company expects a one-time reduction to retained earnings of approximately $3.3 million in the transition to a December 31 valuation date.

The components of net pension expense for the Companys two defined benefit non-contributory pension plans and certain nonqualified supplemental pension plans were:

The Company recognized settlement charges of $2.1 million during the three months ended
March 31,2007 for the payment of lump sums from the nonqualified supplemental retirement plans. The Company is not required to make pension contributions in 2008 and does not currently plan on making discretionary contributions. For the three
months ended March 31, 2008, the Company made benefit payments aggregating $0.3 million to retirees from the nonqualified supplemental retirement plans and expects to make additional benefit payments of approximately $3 million through the
remainder of 2008.

The components of net periodic postretirement benefit expense for the Companys postretirement benefit plans were:

For the three months ended March 31, 2008, the Company made contributions aggregating $0.2
million to the postretirement benefit plan assets. The Company expects to make additional discretionary contributions of approximately $2.4 million to postretirement benefit plan assets through the remainder of 2008.

9. 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 $165 million through October 2015. 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 121 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 sheets. 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, 2008, the fixed price purchases under these guarantees had a maximum term outstanding through December 2008 and an aggregate
purchase price of $4.8 million with a market value of $6 million.

During 2007, Energen Resources entered into an agreement through March
2009 to secure a drilling rig necessary to execute a portion of its drilling plans. In the unlikely event that Energen Resources discontinues use of the drilling rig, Energen Resources total resulting exposure could be up to approximately $7
million depending on the contractors ability to remarket the drilling rig.

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 jurisdictions in which the magnitude and frequency of punitive and other damage awards may bear little or no relation to culpability or actual damages, thus making it difficult to predict litigation results.

Jefferson County, Alabama

In January 2006, RGGS Land and Minerals LTD, L.P. (RGGS) filed a lawsuit in Jefferson County, Alabama, alleging breach of contract with respect to Energen Resources calculation of certain allowed costs and
failure to pay in a timely manner certain amounts due RGGS under a mineral lease. RGGS seeks a declaratory judgment with respect to the parties rights under the lease, reformation of the lease, monetary damages and termination of Energen
Resources rights under the lease. The Occluded Gas Lease dated January 1, 1986 was originally between Energen Resources and United States Steel Corporation (U.S. Steel) as lessor. RGGS became the lessor under the lease as a result of a
2004 conveyance from U.S. Steel to RGGS. Approximately 120,000 acres in Jefferson and Tuscaloosa counties, Alabama, are subject to the lease. Separately on February 6, 2006, Energen Resources received notice of immediate lease termination from
RGGS. During 2007, Energen Resources production associated with the lease was approximately 10.5 Bcf.

RGGS has adopted positions
contrary to the seventeen years of course of dealing between Energen Resources and its original contracting partner, U.S. Steel. The Company believes that RGGS assertions are without merit and that the notice of lease termination is
ineffective. Energen Resources intends to vigorously defend its rights under the lease. The Company remains in possession of the lease, believes that the likelihood of a judgment in favor of RGGS is remote and has made no material accrual with
respect to the litigation or purported lease termination.

Legacy Litigation

During recent years, numerous lawsuits have been filed against oil production companies in Louisiana for restoration of oilfield properties. These suits are referred to in the industry as
legacy litigation because they usually involve operations that were conducted on the affected properties many years earlier. Energen Resources is or has been a party to several legacy litigation lawsuits, most of which result from the
operations of predecessor companies. Based upon information presently available, and in light of available legal and other defenses, contingent liabilities arising from legacy litigation in excess of the Companys accrued provision for
estimated liability are not considered material to the Companys financial position.

Other

Various other pending or threatened legal proceedings are in progress currently, and the Company has accrued a provision for estimated liability.

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.

A discussion of certain litigation in the state of Louisiana related to the restoration of oilfield properties is included above under Legal Matters.

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 of Alagasco.

11. ACQUISITION AND DISPOSITIONS OF OIL AND GAS PROPERTIES

During the three months ended March 31, 2008, Energen Resources capitalized approximately $6.8 million of unproved leaseholds costs, approximately
$5.3 million of which was related to the Companys acreage position in Alabama shale. Energen used its available cash and existing lines of credit to finance these unproved leasehold costs.

In March 2008, Energen Resources recorded in operating revenues a $10.2 million pre-tax gain in other in the first quarter of 2008 resulting from the
property sale of certain Permian Basin oil properties. The Company received approximately $15.5 million pre-tax in cash from the sale of this property.

In May 2007, Energen Resources purchased oil properties in the Permian Basin for $18 million. To finance the acquisition, Energen used its available cash and existing lines of credit.

12. LONG-TERM DEBT

In May 2007, Energen voluntarily
called $100 million Floating Rate Senior Notes due November 15, 2007. In April 2007, Energen voluntarily redeemed $10 million of Medium-Term Notes, Series A, with an annual interest rate of 8.09% due September 15, 2026. Associated with
this redemption, the Company incurred a call premium of 4.045%.

In January 2007, Alagasco issued $45 million of long-term debt with an
interest rate of 5.9% due January 15, 2037. Alagasco used these long-term debt proceeds to redeem the $34.4 million of 6.75% Notes, maturing September 1, 2031 and $10 million of 7.97% Medium-Term Notes maturing September 23, 2026.

13. RECENT PRONOUNCEMENTS OF THE FINANCIAL ACCOUNTING STANDARDS BOARD

The Company partially adopted the provisions of SFAS No. 157 as of January 1, 2008. SFAS No. 157 defines fair value, establishes criteria
to be considered when measuring fair value and expands disclosures about fair value measurements. The additional disclosures for recurring financial instruments required under the standard are included in Note 3, Derivative Commodity Instruments.

In February 2008, the FASB issued FASB Staff Position (FSP) 157-2, Effective Date of FASB Statement No. 157, which delays
the effective date of SFAS No. 157 for nonfinancial assets and nonfinancial liabilities except for items that are recognized or disclosed at fair value in the financial statements on a recurring basis. This FSP defers the effective date of SFAS
No. 157 to fiscal years beginning after November 15, 2008 for those items within the scope of FSP 157-2. The deferred disclosures primarily relate to the Companys asset retirement obligations.

In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities, which permits
entities to measure financial instruments and certain other items at fair value to mitigate volatility in reported earnings. This Statement is effective for fiscal years beginning after November 15, 2007. The Company has not elected the fair
value option for any of its assets or liabilities and, therefore, implementation of this standard did not have a material impact on the consolidated financial position and results of operations.

In December 2007, the FASB issued SFAS No. 141 (revised 2007), Business Combinations, which will improve the relevance, representational
faithfulness, and comparability of the information that a reporting entity provides in its financial reports about a business combination and its effects. This Statement applies prospectively to business combinations for which the acquisition date
is on or after the beginning of the first fiscal year beginning on or after December 15, 2008. The Company is currently evaluating the impact of this Statement.

The FASB issued SFAS No. 160, Noncontrolling Interests in Consolidated Financial Statementsan amendment of ARB No. 51, in December 2007. SFAS No. 160 establishes accounting and
reporting standards for ownership interests in subsidiaries held by parties other than the parent, the amount of consolidated net income attributable to the parent and to the noncontrolling interest, changes in a parents ownership interest,
and the valuation of retained noncontrolling equity investments when a subsidiary is deconsolidated. SFAS No. 160 also establishes disclosure requirements that clearly identify and distinguish between the interests of the parent and the
interests of the noncontrolling owners. This Statement is effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2008. The effect of this Standard on the Company is currently being
evaluated.

In March 2008, the FASB issued SFAS No. 161, Disclosures About Derivative Instruments and Hedging Activities
 an amendment of FASB Statement No. 133. SFAS No. 161 expands quarterly disclosure requirements in SFAS No. 133 about an entitys derivative instruments and hedging activities. SFAS No. 161 is effective for years
beginning after November 1, 2008. The effect of this Standard on the Company is currently being evaluated.

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



RESULTS OF OPERATIONS

Energens net income totaled $116.7 million ($1.62 per diluted share) for the three months ended March 31, 2008 and compared favorably with net
income of $103.9 million ($1.44 per diluted share) for the same period in the prior year. Energen Resources Corporation, Energens oil and gas subsidiary, had net income and income from continuing operations for the three months ended
March 31, 2008, of $72.5 million as compared with $63.2 million in the same quarter in the previous year. Significantly higher commodity prices (approximately $9 million after-tax), increased oil and gas production volumes (approximately $4
million after-tax) and a $6.4 million after-tax gain on the sale of certain Permian Basin oil properties were partially offset by increased lease operating expenses (approximately $5 million after-tax), higher production taxes (approximately $3
million after-tax) and increased depreciation, depletion and amortization (DD&A) expense (approximately $2 million after-tax). Energens natural gas utility, Alagasco, reported net income of $43.7 million in the first quarter of 2008
compared to net income of $40.3 million in the same period last year largely reflecting the utilitys ability to earn on a higher level of equity (approximately $2 million after-tax) and reduced operations and maintenance (O&M) expense
(approximately $2 million after-tax) partially offset by a slight decrease in customer usage (approximately $1 million after-tax).

Oil and Gas
Operations

Revenues from oil and gas operations rose 15.9 percent to $224.9 million for the three months ended March 31, 2008
largely as a result of increased commodity prices as well as the impact of higher production volumes. During the current quarter, revenue per unit of production for natural gas rose 0.5 percent to $7.97 per thousand cubic feet (Mcf), while oil
revenue per unit of production increased 16.3 percent to $67.90 per barrel. Natural gas liquids revenue per unit of production increased 30 percent to an average price of $1.04 per gallon. The Company recorded an after-tax loss of approximately $0.6
million year-to-date on contracts which did not meet the definition of cash flow hedges under Statement of Financial Accounting Standard (SFAS) No. 133, Accounting for Derivative Instruments and Hedging Activities. For the three
months ended March 31, 2008, the Company recorded a $1 million after-tax loss for the ineffective portion of the change in fair value of derivatives accounted for as cash flow hedges.

Production increased primarily due to additional development activities in the San Juan and North Louisiana/East Texas basins partially offset by normal production declines. Natural gas
production from continuing operations in the first quarter rose 5.7 percent to 16.4 billion cubic feet (Bcf), while oil volumes increased 1.8 percent to 944 thousand barrels (MBbl). Natural gas liquids production decreased 11.6 percent to
16.7 million gallons (MMgal) due to normal production declines and severe winter weather in the San Juan Basin. Natural gas comprised approximately 65 percent of Energen Resources production for the current quarter.

Energen Resources may, in the ordinary course of business, be involved in the sale of developed or undeveloped properties. The Company includes gains and
losses on the disposition of these assets in operating revenues. In the first quarter of 2008, Energen Resources recorded a pre-tax gain of $10.3 million largely from the sale of certain Permian Basin oil properties. Energen Resources recorded a
pre-tax gain of $0.3 million in the prior quarter on the sale of various properties.

O&M expense increased $6.1 million for the
quarter. Lease operating expense (excluding production taxes) increased by $7.7 million for the quarter largely due to additional compression costs (approximately $2.7 million), higher transportation costs related to increased San Juan Basin
production (approximately $1.2 million), higher workover expense (approximately $1.3 million), increased repairs and maintenance expense in the San Juan and East Texas basins (approximately $0.7 million), increased electricity costs (approximately
$0.5 million) and increased environmental compliance expense (approximately $0.3 million). Administrative expense decreased $1.9 million for the three months ended March 31, 2008 largely due to lower labor-related expenses. The first quarter of
2007 included a settlement charge for the nonqualified supplemental retirement plan of approximately $1.1 million. Exploration expense rose $0.3 million in the first quarter of 2008.

##### Table of Contents

Energen Resources DD&A expense for the quarter rose $3.9 million. The average DD&A rate for
the current quarter was $1.21 per Mcfe as compared to $1.09 per Mcfe in the same period a year ago. The increase in the current quarter per unit DD&A rate, which contributed approximately $3.3 million, was largely due to higher rates resulting
from an increase in development costs. Increased production volumes also contributed approximately $0.5 million to the increase in DD&A expense in the quarter comparisons.

Energen Resources expense for taxes other than income taxes was $4.5 million higher in the first quarter largely due to production-related taxes. Severance taxes increased $4.7 million
during the three months ended March 31, 2008 over the same quarter in the prior year. Higher oil, natural gas and natural gas liquid commodity market prices and the impact of increased production volumes contributed approximately $4.4 million
and $0.3 million, respectively. Commodity market prices exclude the effects of derivative instruments for purposes of determining severance taxes.

Natural Gas Distribution

Natural gas distribution revenues declined $1.9 million for the quarter largely due to a decline
in customer usage. Although in the first quarter weather was 4.2 percent colder than the same period last year, residential sales volumes decreased due to customer conservation. Commercial and industrial customer sales volumes increased 2.1 percent
while transportation volumes rose 6.5 percent in period comparisons. A decline in gas costs partially offset by an increase in gas purchase volumes resulted in a 4 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 Gas Supply Adjustment (GSA) rider. The GSA rider in Alagascos rate schedule provides for a pass-through of gas price fluctuations to customers without markup. As discussed
further in Future Capital Resources and Liquidity, a continued higher price commodity environment may result in significant increases in the GSA and further customer and usage declines. Alagascos tariff provides a temperature adjustment to
certain customers bills designed to moderate the impact of departures from normal temperatures on Alagascos earnings. The temperature adjustment applies primarily to residential, small commercial and small industrial customers.

As discussed more fully in Note 2, Regulatory Matters, in the Unaudited Condensed Financial Statements, Alagasco is subject to regulation
by the Alabama Public Service Commission (APSC). On December 21, 2007, the APSC issued an order to extend Alagascos rate-setting mechanism. Under the terms of that extension, RSE will continue after December 31, 2014, unless, after
notice to Alagasco and a hearing, the APSC votes to either modify or discontinue the RSE methodology.

O&M expense decreased 5.3
percent in the current quarter primarily due to lower labor-related costs (approximately $1 million) and decreased insurance costs (approximately $1 million). The three months ended March 31, 2007 included a settlement charge for the
nonqualified supplemental retirement plan of approximately $1 million. For the year ended December 31, 2008, O&M expense is expected to increase over the prior year by approximately 3 percent. A 4.1 percent increase in depreciation expense
in the current quarter was primarily due to extension and replacement of the utilitys distribution system and replacement of its 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 decreased $1.1 million in the first quarter of 2008 largely due to the May 2007 voluntary call of the
$100 million Floating Rate Senior Notes due November 15, 2007 partially offset by higher borrowings at Energen Resources. Income tax expense for the Company increased $9.7 million in the current quarter largely due to higher pre-tax income.

FINANCIAL POSITION AND LIQUIDITY



Cash flows from operations for the year-to-date were $159.4 million as compared to $187.9 million in the prior period. Operating cash flow benefited
from higher realized commodity prices and production volumes at Energen Resources and a decrease in income taxes payable related to depreciation and basis differences from the prior period. In the current quarter, these benefits were more than
offset by increased working capital needs which are highly influenced by commodity prices and the timing of payments. Working capital needs at Alagasco were primarily affected by decreased gas costs compared to the prior period and decreased storage
gas inventory.

The Company had a net outflow of cash from investing activities of $69 million for the three months ended
March 31, 2008 primarily due to additions of property, plant and equipment. Energen Resources invested $74.4 million in capital expenditures primarily related to the development of oil and gas properties including approximately $6.8 million of
unproved leaseholds, primarily shale related. During the current quarter, Energen Resources received cash proceeds of $15.5 million primarily from the sale of certain Permian Basin oil properties. Utility capital expenditures totaled $12.9 million
in the year-to-date and primarily represented expansion and replacement of its distribution system and support facilities.

The Company
used $85.1 million for net financing activities in the year-to-date primarily for the repayment of short-term debt borrowings and the payment of dividends to common shareholders partially offset by the tax benefit on stock compensation.

FUTURE CAPITAL RESOURCES AND LIQUIDITY



The Company plans to continue investing significant capital in Energen Resources oil and gas production operations. For 2008, the Company expects
its oil and gas capital spending to total approximately $330 million, including $305 million for existing properties. The Company expects capital spending at Energen Resources to total approximately $271 million during 2009, including approximately
$260 million for existing properties.

The Company also may allocate additional capital for other oil and gas activities such as property
acquisitions, additional accelerated development of existing properties and the exploration and further development of potential shale plays primarily in Alabama. Energen Resources may evaluate acquisition opportunities which arise in the
marketplace and from time to time will pursue acquisitions that meet Energens acquisition criteria. Energen Resources ability to invest in property acquisitions is subject to market conditions and industry trends. Property acquisitions
are not included in the aforementioned estimate of oil and gas investments and could result in capital expenditures different from those outlined above. In October 2006, Energen Resources and Chesapeake Energy Corporation (Chesapeake) signed an
agreement to form an area of mutual interest (AMI) through which they will pursue new leases, exploration, development and operations on a 50-50 basis in an area which encompasses Alabama and some of Georgia, for at least the next 10 years. Energen
Resources and Chesapeake continue to lease shared acreage in the AMI; as of March 31, 2008, Energen Resources had approximately $34 million of unproved leasehold costs related to its lease position in Alabama shale. As of May 8, 2008,
Energen Resources net acreage position totaled approximately 320,000 acres and represents multiple shale opportunities. During the first quarter of 2008, the Company initiated drilling activities for three wells as part of a 5 to 10 well test
program. The Company has not included in its capital spending estimates discussed above any amounts associated with exploratory drilling and/or future potential development for the Alabama shale position.

To finance capital spending at Energen Resources, the Company primarily expects to use internally generated cash flow supplemented by its short-term
credit facilities. The Company also may issue long-term debt and equity periodically to replace short-term obligations, enhance liquidity and provide for permanent financing.

Energen also plans to consider stock repurchases as a capital investment. Energen may buy shares from time to time on the open market or in negotiated purchases. The timing and amounts of any
repurchases are subject to changes in market conditions. The Company did not repurchase shares of common stock for this program during the three months ended March 31, 2008 and 2007. The Company currently plans to continue utilizing internally
generated cash flow to fund any future stock repurchases. During the three months ended March 31, 2008, the Company had noncash purchases of approximately $27 million of Company common stock in conjunction with tax withholdings on its
non-qualified deferred compensation plan and other stock compensation. The Company utilized internally generated cash flows in payment of the related tax withholdings.

Energen Resources has experienced various market driven conditions generally caused by the increased
commodity price environment including, but not limited to, higher workover and maintenance expenses, increased taxes and other field-service-related expenses. The Company anticipates influences such as weather, natural disasters, changes in global
economics and political unrest will continue to contribute to increased price volatility in the near term. Commodity price volatility will affect the Companys revenue and associated cash flow available for investment.

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 to its estimated oil, natural gas and natural gas liquids production. 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 operating revenues 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.

Alagasco also enters into cash flow derivative commodity instruments to
hedge its exposure to price fluctuations on its 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 in accordance
with SFAS No. 71, Accounting for the Effects of Certain Types of Regulation. Any gains or losses are passed through to customers using the mechanisms of the GSA in compliance with Alagascos APSC-approved tariff.

Energen Resources and Alagasco utilize derivative instruments which may include natural gas and crude oil over-the-counter (OTC) 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. At March 31, 2008, the counterparty agreements under which the Company had active positions did not include collateral posting requirements. Energen
Resources was in a net loss position with all of its counterparties as of March 31, 2008. The Company believes the creditworthiness of these counterparties is satisfactory. These hedge transactions are pursuant to standing authorizations by the
Board of Directors, which do not authorize speculative positions.

Energen Resources entered into the following transactions for the
remainder of 2008 and subsequent years:

Realized prices are anticipated to be lower than New York Mercantile Exchange (NYMEX) prices due to basis
differences and other factors.

Effective January 1, 2008, the Company partially adopted SFAS No. 157, Fair Value
Measurements, under the provisions of the Financial Accounting Standards Board (FASB) Staff Position 157-2, Effective Date of FASB Statement No. 157. SFAS No. 157 defines fair value, establishes a framework for measuring
fair value and expands disclosures about fair value measurements. As defined under SFAS No. 157, fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market
participants at the measurement date (exit price). SFAS No.157 establishes a fair value hierarchy that prioritizes the inputs used to measure fair value defined as follows:



|          |  |                                                                                                                                                            
|--------- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------
|Level 1  |  | Unadjusted quoted prices in active markets for identical assets or liabilities;                                                                            
|Level 2  |  | Pricing inputs other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable as of the reporting
date;
|Level 3  |  | Pricing that requires inputs that are both significant to the fair value measure and unobservable.                                                         

Over-the-counter derivatives are valued using market transactions and other market evidence
whenever possible, including market-based inputs to models and broker or dealer quotations. These OTC derivative contracts trade in less liquid markets with limited pricing information, and the determination of fair value is inherently more
difficult than for actively traded, unadjusted quoted prices. OTC derivatives for which the Company is able to substantiate fair value through directly observable market prices are classified within Level 2 of the fair value hierarchy. These Level 2
fair values consist of NYMEX swaps. OTC derivatives valued using unobservable market prices have been classified within Level 3 of the fair value hierarchy. These Level 3 fair values include basin specific, basis and liquids swaps. The Company
believes that these prices represent the best estimate of the exit price for these instruments as of the balance sheet date and are representative of the prices for which the contract will ultimately settle or realize.

The following table sets forth derivative assets and liabilities that were accounted for on a recurring basis as follows:

|                         |  |                |          |   |         |   |         |       |  |   |          |  
|------------------------ |  | -------------- | -------- | - | ------- | - | ------- | ----- |  | - | -------- | -
|                         |  | March 31, 2008 |         
|(in thousands)           |  | Level 2        |          |   | Level 3 |   |         | Total | 
|Current assets           |  | $              | -        |   |         | $ | -       |       |  | $ | -        |  
|Noncurrent assets        |  |                | 406      |   |         |   | -       |       |  |   | 406      |  
|Current liabilities      |  |                | (145,824 | ) |         |   | (61,353 | )     |  |   | (207,177 | )
|Noncurrent liabilities   |  |                | (58,564  | ) |         |   | (9,051  | )     |  |   | (67,615  | )
|Net liability recognized |  | $              | (203,982 | ) |         | $ | (70,404 | )     |  | $ | (274,386 | )

Level 3 liabilities as of March 31, 2008 represent approximately 4 percent of total
liabilities. Changes in fair value result from price changes in the underlying commodity. The Company has prepared a sensitivity analysis to evaluate the hypothetical effect that changes in the prices used to estimate fair value would have on the
fair value of its derivative instruments. The Company estimates that a 10 percent increase or decrease in commodities prices would result in a $64.9 million change in the fair value of open Level 3 derivative contracts. The resulting impact upon the
results of operations for Level 3 derivatives would be immaterial. Liquidity requirements to meet the obligation would not be significantly impacted as gains and losses on the derivative contracts would be similarly offset by sales at the spot
market price.

##### Table of Contents

The Companys use of commodity price hedges for a portion of its gas supply needs is reflected in
the utilitys current rates. Alagascos rate schedules for natural gas distribution charges contain a GSA rider which permits the pass-through to customers for changes in the cost of gas supply. The GSA rider is designed to capture the
Companys cost of natural gas and provides for a pass-through of gas cost fluctuations to customers without markup; the cost of gas includes the commodity cost, pipeline capacity, transportation and fuel costs, and risk management gains and
losses.

A continued higher price commodity environment has the potential to produce adverse effects for the utility. Alagasco could have
significant GSA increases in future periods. Sustained higher natural gas prices may decrease Alagascos customer base and could result in a further decline in per customer use. Alagasco will continue to monitor its bad debt reserve and will
make adjustments as required based on the evaluation of its receivables which are impacted by natural gas prices. Further, during the first quarter, Alagasco experienced a decline in usage by its construction industry related customers. Alagasco
expects this usage decline to continue in the near term and currently anticipates utilizing its Enhanced Stability Reserve (ESR) of approximately $4 million during 2008. Absent the ESR reserve, projected earnings for 2008 would be lower by
approximately $2.5 million. Under the provisions of the Rate Stabilization and Equalization rate-setting process, Alagascos rates in future periods will be adjusted to allow the utility to earn within its allowed range of return on average
equity of 13.15 percent to 13.65 percent.

Alagasco maintains an investment in storage gas that is expected to average approximately $72
million in 2008 but will vary depending upon the price of natural gas. During 2008 and 2009, Alagasco plans to invest an estimated $69 million and $75 million, respectively, in utility capital expenditures for normal distribution and support
systems. The utility anticipates funding these capital requirements through internally generated capital and the utilization of short-term credit facilities. Alagasco issued $45 million in long-term debt with an interest rate of 5.9% in January 2007
and redeemed $34.4 million of 6.75% Notes maturing September 1, 2031 and $10 million of 7.97% Medium-Term Notes maturing September 23, 2026 in the same period in order to capitalize on lower interest rates.

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. On September 25, 2007, Moodys Investors Service (Moodys) downgraded the debt rating of Energen to Baa3 senior unsecured from Baa2. Energens debt
rating of Baa3 remains investment grade and reflects Moodys assignment of increased risk exposure related to the growth of its oil and gas operations in contrast to its legacy natural gas distribution assets. Moodys also confirmed the
debt rating of Alagasco during this review as A1 senior unsecured. On October 31, 2007, Standard & Poors affirmed its BBB+ corporate credit rating on Energen and Alagasco; the outlook remained stable. 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. To help finance its growth plans and
operating needs, the Company currently has available short-term credit facilities aggregating $435 million of which Energen has available $285 million, Alagasco has available $100 million and $50 million is available to either Company.

Dividends

Energen expects to pay annual cash
dividends of $0.48 per share on the Companys common stock in 2008. The amount and timing of all dividend payments is subject to the discretion of the Board of Directors and is based upon business conditions, results of operations, financial
conditions and other factors.

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. There have been no material changes to the contractual cash
obligations of the Company since December 31, 2007.

Recent Pronouncements of the Financial Accounting Standards Board

The Company partially adopted the provisions of SFAS No. 157, Fair Value Measurements, as of January 1, 2008. SFAS 157 defines fair
value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. The additional disclosures required under the standard are included in Note 3, Derivative Commodity Instruments.

##### Table of Contents

In February 2008, the FASB issued FASB Staff Position (FSP) 157-2, Effective Date of FASB Statement
No. 157, which delays the effective date of SFAS No. 157 for nonfinancial assets and nonfinancial liabilities except for items that are recognized or disclosed at fair value in the financial statements on a recurring basis. This FSP
defers the effective date of SFAS No. 157 to fiscal years beginning after November 15, 2008 for those items within the scope of FSP 157-2. The deferred disclosures primarily relate to the Companys asset retirement obligations.

In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities,
which permits entities to measure financial instruments and certain other items at fair value to mitigate volatility in reported earnings. This Statement is effective for fiscal years beginning after November 15, 2007. The Company has not
elected the fair value option for any of its assets or liabilities and, therefore, implementation of this standard did not have a material impact on the consolidated financial position and results of operations.

In December 2007, the FASB issued SFAS No. 141 (revised 2007), Business Combinations, which will improve the relevance, representational
faithfulness, and comparability of the information that a reporting entity provides in its financial reports about a business combination and its effects. This Statement applies prospectively to business combinations for which the acquisition date
is on or after the beginning of the first fiscal year beginning on or after December 15, 2008. The Company is currently evaluating the impact of this Statement.

The FASB issued SFAS No. 160, Noncontrolling Interests in Consolidated Financial Statementsan amendment of ARB No. 51, in December 2007. SFAS No. 160 establishes
accounting and reporting standards for ownership interests in subsidiaries held by parties other than the parent, the amount of consolidated net income attributable to the parent and to the noncontrolling interest, changes in a parents
ownership interest, and the valuation of retained noncontrolling equity investments when a subsidiary is deconsolidated. SFAS No. 160 also establishes disclosure requirements that clearly identify and distinguish between the interests of the
parent and the interests of the noncontrolling owners. This Statement is effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2008. The effect of this Standard on the Company is currently
being evaluated.

In March 2008, the FASB issued SFAS No. 161, Disclosures About Derivative Instruments and
Hedging Activities  an amendment of FASB Statement No. 133. SFAS No. 161 expands quarterly disclosure requirements in SFAS No. 133 about an entitys derivative instruments and hedging activities. SFAS No. 161 is
effective for years beginning after November 1, 2008. The effect of this Standard on the Company is currently being evaluated.

FORWARD
LOOKING STATEMENTS



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, investments, 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, the Companys 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, gas and natural gas liquid 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 and Drilling: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. Anticipated
drilling plans and capital expenditures may also change due to weather, manpower and equipment availability, changing emphasis by management and a variety of other factors which could result in actual drilling and capital expenditures being
substantially different than currently planned.

Energen Resources Hedging:Although Energen Resources makes use of futures,
swaps, options and fixed-price contracts to mitigate price risk, fluctuations in future commodity prices could materially affect the Companys financial position, 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, options 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
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s 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 oil and gas production activities of Energen Resources and the gas distribution activities of Alagasco 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 operations and substantial
losses to the Company. In accordance with customary industry practices, the Company maintains 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s 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 to its estimated 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 natural gas and crude oil 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 amounts. 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, 2010.

A failure to meet sales volume targets at Energen Resources or gas supply targets at Alagasco due to miscalculations, weather events, natural disasters, accidents, mechanical failure, criminal
act or otherwise could leave the Company or Alagasco exposed to its counterparties in commodity hedging contracts and result in material adverse financial losses.

See Note 3, Derivative Commodity Instruments, in the Notes to the Unaudited Condensed Financial Statements for details related to the Companys hedging activities.

The Companys interest rate exposure as of March 31, 2008, was minimal as all long-term debt obligations were at fixed rates.
