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 June 30, 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 June 30, 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 June 30,
2008, $263.6 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 $0.5 million after-tax loss for the three months ended June 30, 2008, and a $1.5 million after-tax loss year-to date. Also, the Company recorded an
after-tax loss of approximately $1.3 million during the second quarter of 2008 and a $1.9 million after-tax loss year-to-date on contracts which did not meet the definition of cash flow hedges under SFAS No. 133. As of June 30, 2008, the
Company had 0.59 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 as compared to markets with actively traded, unadjusted quoted
prices; accordingly, the determination of fair value is inherently more difficult. 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.

During the six months ended June 30, 2008, Energen Resources awarded 1,805 Petrotech units with a two year vesting period and a fair value of $77.32 as of June 30, 2008. During the year-to-date, Energen Resources also awarded 1,014
Petrotech units with a three year vesting period and a fair value of $76.84 as of June 30, 2008.

respectively, 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 and an
adjustment to the regulatory assets and liabilities of Alagasco totaling approximately $3.3 million pre-tax 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 first quarter of 2007 for the
payment of lump sums from the nonqualified supplemental retirement plans. The Company is not required to make pension contributions in 2008 but currently plans on making discretionary contributions of approximately $11 million through year-end. For
the three months and six months ended June 30, 2008, the Company made benefit payments aggregating $50,000 and $0.3 million, respectively, to retirees from the nonqualified supplemental retirement plans and expects to make additional benefit
payments of approximately $2.9 million through the remainder of 2008.

For the three months and six months ended June 30, 2008, the Company made contributions
aggregating $1 million and $1.2 million, respectively, to the postretirement benefit plan assets. The Company expects to make additional discretionary contributions of approximately $1.4 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 $147 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 114 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 June 30, 2008, the fixed price purchases under these guarantees had a maximum
term outstanding through February 2009 and an aggregate purchase price of $3.5 million with a market value of $5.1 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 $5 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



18

##### Table of Contents

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 six months ended June 30, 2008, Energen Resources capitalized approximately $15.5 million of unproved leaseholds costs, approximately
$11.2 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.

Energen Resources recorded a $10.3 million pre-tax gain in other operating revenues from the March 2008 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 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 is intended to improve the relevance, representational faithfulness, and comparability of the information that a reporting entity



20



---

##### Table of Contents

provides in its financial reports about a business combination. This Statement applies prospectively to business combinations occurring in the 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.

In May 2008, the FASB issued SFAS
No. 162, The Hierarchy of Generally Accepted Accounting Principles. SFAS No. 162 identifies the sources of accounting principles and the framework for selecting the principles used in the preparation of financial statements of
nongovernmental entities that are presented in conformity with generally accepted accounting principles in the United States. This Statement is effective 60 days following certain approvals by the Securities and Exchange Commission. The effect of

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



RESULTS OF OPERATIONS

Energens net income totaled $66.9 million ($0.93 per diluted share) for the three months ended June 30, 2008 compared with
net income of $67.9 million ($0.94 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 June 30, 2008, of $70.6 million as
compared with $66.9 million in the same quarter in the previous year. Significantly higher commodity prices (approximately $12 million after-tax) and increased oil and gas production volumes (approximately $5 million after-tax) were partially offset
by higher production taxes (approximately $5 million after-tax), increased depreciation, depletion and amortization (DD&A) expense (approximately $3 million after-tax), higher exploration expense (approximately $2 million after-tax) and
increased lease operating expenses (approximately $1.5 million after-tax). Energens natural gas utility, Alagasco, reported a net loss of $3.1 million in the second quarter of 2008 compared to net income of $1.4 million in the same period last
year. This deficit was affected primarily by the timing differences associated with rate recovery under Alagascos rate mechanism (approximately $2.4 million after-tax) and a decline in customer usage and other (approximately $2 million
after-tax).

For the 2008 year-to-date, Energens net income totaled $183.6 million ($2.55 per diluted share) and compared favorably
to net income of $171.8 million ($2.38 per diluted share) for the same period in the prior year. Energen Resources generated net income for the six months ended June 30, 2008, of $143.1 million as compared with $130.1 million in the previous
period primarily as a result of higher commodity prices (approximately $21 million after-tax), increased production volumes (approximately $9 million after-tax), a $6.4 million after-tax gain on the sale of certain Permian Basin oil properties
partially offset by the impact of higher production taxes (approximately $8 million after-tax), increased lease operating expenses (approximately $6 million after-tax), higher DD&A expense (approximately $5 million after-tax) and the decreased
benefit from the Section 199 production activities deduction (approximately $2 million after-tax). Alagascos net income of $40.6 million in the current year-to-date compared to net income of $41.7 million in the same period in the
previous year largely reflecting the utilitys ability to earn on a higher level of equity and lower operations and maintenance (O&M) expense of approximately $1.4 million after-tax. These items were more than offset by a decrease in
customer usage and other (approximately $2.9 million after-tax) and timing differences associated with rate recovery.

Oil and Gas Operations

Revenues from oil and gas operations rose 14 percent to $231.8 million for the three months ended June 30, 2008 and 14.9 percent
to $456.7 million in the year-to-date 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 3.8 percent to $8.25 per
thousand cubic feet (Mcf), while oil revenue per unit of production increased 16.4 percent to $74.51 per barrel. Natural gas liquids revenue per unit of production increased 27.6 percent to an average price of $1.11 per gallon. In the year-to-date,
revenue per unit of production for natural gas increased 2.1 percent to $8.11 per Mcf, oil revenue per unit of production increased 16.5 percent to $71.31 per barrel and natural gas liquids revenue per unit of production rose 30.1 percent to an
average price of $1.08 per gallon.

The Company recorded an after-tax loss of approximately $1.3 million during the second quarter of 2008
and a $1.9 million after-tax loss 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 ineffective portion of the change in fair value of derivatives accounted for as cash flow hedges, Energen Resources recorded a $0.5 million after-tax loss for the three months ended June 30, 2008, and a $1.5 million
after-tax loss year-to date.

Production increased primarily due to additional development activities in the San Juan, Permian and North
Louisiana/East Texas basins partially offset by normal production declines and other. Natural gas production from continuing operations in the first quarter rose 4.5 percent to 16.4 billion cubic feet (Bcf), oil volumes increased 6.2 percent to
1,006 thousand barrels (MBbl) and natural gas liquids production decreased 5.2 percent to 18.1 million gallons (MMgal). For the year-to-date, natural gas production from continuing operations increased 5.1 percent to 32.8 Bcf, while oil
volumes rose 4.1 percent to 1,950 MBbl. Natural gas liquids production decreased 8.2 percent to 34.9 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 and the year-to-date.

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 second quarter of 2008, Energen Resources recorded a pre-tax loss of $0.2 million and a pre-tax gain of $10.1 million in
the year-to-date largely from the sale of certain Permian Basin oil properties. Energen Resources recorded a pre-tax gain of $14,000 and a pre-tax gain of $130,000 in the three months and six months ended June 30, 2007, respectively, on the
sale of various properties.

O&M expense increased $7.8 million for the quarter and $13.9 million in the year-to-date. Lease operating
expense (excluding production taxes) increased by $2.5 million for the quarter largely due to higher transportation costs related to increased San Juan Basin production (approximately $0.9 million), increased repairs and maintenance expense in the
San Juan Basin (approximately $0.8 million), higher workover expense (approximately $0.5 million),and increased environmental compliance expense (approximately $0.4 million). In the year-to-date, lease operating expense (excluding production taxes)
rose $10.2 million primarily due to additional compression costs (approximately $2.4 million), higher workover expense (approximately $1.8 million), higher transportation costs related to increased San Juan Basin production (approximately $1.6
million), increased repairs and maintenance expense in the San Juan Basin (approximately $1.5 million), higher labor costs (approximately $1 million), increased electricity costs (approximately $0.9 million) and increased environmental compliance
expense (approximately $0.7 million) partially offset by lower ad valorem taxes (approximately $0.9 million). Administrative expense increased $2.5 million and $0.6 million for the three months and six months ended June 30, 2008, respectively,
largely due to higher 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 $2.8 million in the second quarter of 2008
and $3 million in the year-to-date primarily due to mechanical difficulties encountered while drilling an exploratory well in the San Juan Basin.

Energen Resources DD&A expense for the quarter rose $5 million and increased $8.9 million year-to-date. The average DD&A rate for the current quarter was $1.25 per thousand cubic feet equivalent (Mcfe) as compared to $1.09 per
Mcfe in the same period a year ago. For the six months ended June 30, 2008, the average depletion rate was $1.23 per Mcfe as compared to $1.09 per Mcfe in the previous period. The increase in the current quarter and year-to-date per unit
DD&A rate, which contributed approximately $3.7 million and $6.9 million, respectively, was largely due to higher rates resulting from an increase in development costs. Increased production volumes also contributed approximately $1.2 million and
$1.8 million to the increase in DD&A expense in the three months and six months ended June 30, 2008, respectively.

Energen
Resources expense for taxes other than income taxes was $8 million and $12.5 million higher in the three months and six months ended June 30, 2008, respectively, largely due to production-related taxes. In the current quarter, higher oil,
natural gas and natural gas liquid commodity market prices and the impact of increased production volumes contributed approximately $7.5 million and $0.5 million, respectively. Increased commodity market price and higher production volumes
contributed approximately $11.7 million and $0.8 million, respectively, in the year-to-date. Commodity market prices exclude the effects of derivative instruments for purposes of determining severance taxes.

Natural Gas Distribution

Natural gas distribution
revenues declined $2.1 million for the quarter largely due to a decrease in customer usage partially offset by an increase in gas costs. Weather that was 16.7 percent colder than in the same quarter in the prior year contributed to a slight increase
in residential sales volumes largely offset by a decline in weather normalized customer usage. Commercial and industrial customer sales volumes remained stable while transportation volumes declined 7.6 percent in period comparisons. Revenues for the
year-to-date declined $4 million largely due to a decrease in customer usage. For the year-to-date, weather was 6 percent colder compared to the same period last year. Residential sales volumes remained stable as the increase in temperature
sensitive volumes were offset by a decline in weather normalized customer usage, while commercial and industrial customer sales volumes increased 1.6 percent. Transportation volumes also did not change in period comparisons. An increase in gas costs
partially offset by a decrease in gas purchase volumes resulted in a 4.7 percent increase in cost of gas for the quarter. For the year-to-date, lower gas purchase volumes contributed to a 1.9 percent decrease in cost of gas. 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 rose 4.2 percent in the current quarter primarily due to increased consulting fees (approximately $0.8 million), increased
labor-related costs (approximately $0.5 million) and higher distribution expenses (approximately $0.8 million). In the six months ended June 30, 2008, O&M expense decreased slightly. Decreased insurance costs (approximately $1.2 million),
decreased bad expense (approximately $0.7 million) and lower labor-related costs (approximately $0.6 million) were largely offset by higher distribution expenses (approximately $1.1 million) and increased consulting fees (approximately $1 million).
The first quarter of 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 3.5 percent increase in depreciation expense in the current quarter and a 3.8 percent increase in the
year-to-date 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 $1.8 million in the first quarter of 2008 and $2.9 million in the year-to-date largely due
to the May 2007 voluntary call of the $100 million Floating Rate Senior Notes due November 15, 2007 along with lower short-term borrowings. Income tax expense for the Company increased $3.1 million in the current quarter and $12.8 million
year-to-date largely due to higher pre-tax income along with the decreased benefit of the Section 199 deduction. The Section 199 deduction decreased $1.5 million and $2.4 million during the three months and six months ended June 30,
2008, respectively.

FINANCIAL POSITION AND LIQUIDITY



Cash flows from operations for the year-to-date
were $315.4 million as compared to $284.4 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. The Companys working capital needs were also influenced by commodity prices and the timing of payments. Negative working capital arising in large part from the current portion of cash flow hedges is
expected to be offset as revenues are realized from production. Working capital needs at Alagasco were additionally affected by decreased storage gas inventory compared to the prior period.

The Company had a net outflow of cash from investing activities of $182.6 million for the six months ended June 30, 2008 primarily due to additions of property, plant and equipment. Energen
Resources invested $172.9 million in capital expenditures primarily related to the development of oil and gas properties including approximately $15.5 million of unproved leaseholds, primarily shale related. During the year-to-date, Energen
Resources received cash proceeds of $15.7 million primarily from the sale of certain Permian Basin oil properties. Utility capital expenditures totaled $28.6 million in the year-to-date and primarily represented expansion and replacement of its
distribution system and support facilities.

The Company used $131.8 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



Oil and Gas Operations

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, higher capital costs 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.

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 $360 million, including $327 million for existing properties. The Company currently expects capital spending at Energen Resources to total approximately $271 million during 2009, including
approximately $260 million for existing properties. The 2009 projection may be revised as Energen Resources completes its formal budgeting process in late 2008.

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 June 30, 2008, Energen Resources had approximately
$40 million of unproved leasehold costs related to its lease position in Alabama shale. Energen Resources net acreage position currently totals approximately 327,000 acres and represents multiple shale opportunities. During the first quarter
of 2008, the Company initiated drilling activities for three wells as part of its well test program. Two of these wells are waiting on completion and the third well is nearing its total depth. Further testing must be completed before the Company can
be certain whether one or more of these formations and concepts will be economically viable. 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.

Natural Gas Distribution

Since 2005, the higher
price commodity environment has resulted in a decline in the utilitys customer base of approximately 1% annually and has the potential to produce continued adverse effects for the utility. Alagasco could have significant GSA increases in
future periods. Sustained higher natural gas prices may further 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 six months ended June 30, 2008, 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 $71 million in 2008 but

will vary depending upon the price of natural gas. During 2008 and 2009, Alagasco plans to invest an estimated $66 million and $71 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 also expects to
receive a cash benefit in the year ended December 31, 2008 from an approximate $29 million tax refund from 2007 which resulted from an approved change in a tax accounting method relating to the Companys recovery of its gas distribution
property.

Derivative Commodity Instruments

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. 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.

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 June 30, 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 June 30, 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 primarily
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 as compared to markets with actively traded, unadjusted quoted
prices; accordingly, the determination of fair value is inherently more difficult. 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 liabilities that were measured at fair value on a recurring basis:



|                         |  |               |          |   |         |   |          |       |  |   |          |  
|------------------------ |  | ------------- | -------- | - | ------- | - | -------- | ----- |  | - | -------- | -
|                         |  | June 30, 2008 |         
|(in thousands)           |  | Level 2       |          |   | Level 3 |   |          | Total | 
|Current liabilities      |  | $             | (324,407 | ) |         | $ | (124,457 | )     |  | $ | (448,864 | )
|Noncurrent liabilities   |  |               | (203,771 | ) |         |   | (91,825  | )     |  |   | (295,596 | )
|Net liability recognized |  | $             | (528,178 | ) |         | $ | (216,282 | )     |  | $ | (744,460 | )

Level 3 liabilities as of June 30, 2008 represent approximately 10 percent of total
liabilities. Changes in fair value primarily 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 $73.6 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.

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 or six months ended June 30, 2008 and 2007. Currently, the Company expects any future stock repurchases to be funded through internally generated cash flow. During the six months
ended June 30, 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.

Short-Term Credit Facilities

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 $455 million of which Energen has available $285 million, Alagasco has available $100 million and $70 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.

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 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 is intended to improve the relevance, representational faithfulness, and comparability of the information
that a reporting entity provides in its financial reports about a business combination. This Statement applies prospectively to business combinations occurring in the 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.

In May 2008, the FASB issued SFAS No. 162, The Hierarchy of Generally Accepted Accounting Principles. SFAS No. 162
identifies the sources of accounting principles and the framework for selecting the principles used in the preparation of financial statements of nongovernmental entities that are presented in conformity with generally accepted accounting principles
in the United States. This Statement is effective 60 days following certain approvals by the Securities and Exchange Commission. 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
June 30, 2008, was minimal as all long-term debt obligations were at fixed rates.
