FOR A MORE COMPLETE DEFINITION OF CERTAIN TERMS DEFINED BELOW, PLEASE REFER TO
RULE 4-10(A) OF REGULATION S-X, PROMULGATED PURSUANT TO THE SECURITIES ACT OF
1933 AND THE SECURITIES EXCHANGE ACT OF 1934, EACH AS AMENDED.

BASIS The difference between the futures price for a
commodity and the corresponding cash spot price. The
differential commonly is related to factors such as
product quality, location and contract pricing.

BASIN-SPECIFIC A type of derivative contract whereby the contract's
settlement price is based on specific geographic
basin indices.

BEHIND PIPE RESERVES Oil or gas reserves located above or below the
currently producing zone(s) which cannot be
extracted until a recompletion or pay-add occurs.

CASH FLOW HEDGE The designation of a derivative instrument to reduce
the exposure to variability in cash flows from the
forecasted sale of oil, gas or natural gas liquids
production whereby the gains (losses) on the
derivative transaction are anticipated to offset the
losses (gains) on the forecasted sale.

COLLAR A financial arrangement that effectively establishes
a price range for the commodity. The producer only
bears the risk of fluctuation between the minimum (or
floor) price and the maximum (or ceiling) price.

DEVELOPMENT WELL A well drilled within the proved area of an oil or
gas reservoir to the depth of a statigraphic horizon
known to be productive.

EXPLORATORY WELL A well drilled to a previously untested geologic
structure to determine the presence of oil or gas.

FUTURES CONTRACT An exchange-traded legal contract to buy or sell a
standard quantity and quality of a commodity at a
specified future date and price. Such contracts offer
liquidity and minimal credit risk exposure but lack
the flexibility of swap contracts.

HEDGING The use of derivative commodity instruments such as
futures, swaps and collars to help reduce financial
exposure to commodity price volatility.


LIQUIFIED NATURAL GAS Natural gas that is liquified by reducing the
(LNG) temperature to negative 260 degrees Fahrenheit. LNG
typically is used to supplement traditional natural
gas supplies during periods of peak demand.

LONG-LIVED RESERVES Reserves generally considered to have a productive
life of approximately 10 years or more, as measured
by the reserves-to-production ratio.

NATURAL GAS LIQUIDS (NGL) Liquid hydrocarbons that are extracted and separated
from the natural gas stream. NGL products include
ethane, propane, butane, natural gasoline and other
hydrocarbons.

ODORIZATION A characteristic odor added to natural gas so that
leaks can be readily detectable by smell.

OPERATIONAL ENHANCEMENT Any action undertaken to improve production
efficiency of oil and gas wells and/or reduce well
costs.

OPERATOR The company responsible for exploration, development
and production activities for a specific project.

PAY-ADD An operation within a currently producing wellbore
that attempts to access and complete an additional
pay zone(s) while maintaining production from the
existing completed zone(s).

PAY ZONE The formation from which oil and gas is produced.

PROVED DEVELOPED RESERVES The portion of proved reserves which can be expected
to be recovered through existing wells with existing
equipment and operating methods.



PROVED RESERVES Estimated quantities of crude oil, natural gas and
natural gas liquids that geological and engineering
data demonstrate with reasonable certainty to be
recoverable in future years from known reservoirs
under existing economic and operating conditions.

PROVED UNDEVELOPED The portion of proved reserves which can be expected
RESERVES (PUD) to be recovered from new wells on undrilled proved
acreage or from existing wells where a relatively
major expenditure is required for completion.

PUT OPTION A contract that gives the purchaser the right, but
not the obligation, to sell the underlying commodity
at a certain price on or before an agreed date.

RECOMPLETION An operation within an existing wellbore whereby a
completion in one pay zone is abandoned in order to
attempt a completion in a different pay zone.

RESERVES-TO- Ratio expressing years of supply determined by
PRODUCTION RATIO dividing the remaining recoverable reserves at year
end by actual annual production volumes.

SECONDARY RECOVERY The process of injecting water, gas, etc., into a
formation in order to produce additional oil
otherwise unobtainable by initial recovery efforts.

SWAP A contractual arrangement in which two parties,
called counterparties, effectively agree to exchange
or "swap" variable and fixed rate payment streams
based on a specified commodity volume. The contracts
allow for flexible terms such as specific quantities,
settlement dates and location but also expose the
parties to counterparty credit risk.

TRANSPORTATION Moving gas through company pipelines on a contract
basis for others.

THROUGHPUT Total volumes of natural gas sold or transported by
the gas utility.

WORKING INTEREST The ownership interest in the oil and gas properties
which is burdened with the cost of development and
operation of the property.

WORKOVER A major remedial operation on a completed well to
restore, maintain, or improve the well's production
such as deepening the well or plugging back to
produce from a shallow formation.

e Following a unit of measure denotes that the oil and
natural gas liquids components have been converted to
cubic feet equivalents at a rate of 6 thousand cubic
feet per barrel.

FORWARD-LOOKING STATEMENT AND RISK: 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 Company's forward-looking statements do not reflect
the impact of possible or pending acquisitions, divestitures or restructurings.
The Company cannot guarantee the absence of errors in input data, calculations
and formulas used in its estimates, assumptions and forecasts. The Company
undertakes no 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, future business decisions, and other uncertainties,
all of which are difficult to predict.

There are numerous uncertainties inherent in estimating quantities of proved oil
and gas reserves and in projecting future rates of production and timing of
development expenditures. The total amount or timing of actual future production
may vary significantly from reserve and production estimates. In the event
Energen Resources Corporation is unable to fully invest its planned acquisition,
development and exploratory expenditures, future operating revenues, production,
and proved reserves could be negatively affected. The drilling of development
and exploratory wells can involve significant risks, including those related to
timing, success rates and cost overruns and these risks can be affected by lease
and rig availability, complex geology and other factors.

Although Energen Resources makes use of futures, swaps and fixed-price contracts
to mitigate risk, fluctuations in future oil and gas prices could materially
affect the Company's financial position and results of operation; 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.

PART I

ITEM 1. BUSINESS

GENERAL

Energen Corporation is a Birmingham-based diversified energy holding company
engaged primarily in the acquisition, development, exploration and production of
oil, natural gas and natural gas liquids in the continental United States and in
the purchase, distribution, and sale of natural gas, principally in central and
north Alabama. Its two major subsidiaries are Energen Resources Corporation and
Alabama Gas Corporation (Alagasco).

Energen was incorporated in Alabama in 1978 in connection with the
reorganization of its oldest subsidiary, Alagasco. Alagasco was formed in 1948
by the merger of Alabama Gas Company into Birmingham Gas Company, the
predecessors of which had been in existence since the mid-1800s. Alagasco became
a public company in 1953. Energen Resources was formed in 1971 as a subsidiary
of Alagasco and became a subsidiary of Energen in the 1978 reorganization.

On December 5, 2001, the Board of Directors of the Company approved a change in
the Company's fiscal year end from September 30 to December 31, effective
January 1, 2002. Alagasco retained a September 30 fiscal year end for rate
setting purposes.

The Company maintains a Web site with the address www.energen.com. The Company
does not include the information contained on its Web site as part of this
report nor is the information incorporated by reference into


3


this report. The Company makes available free of charge through its Web site the
annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports
on Form 8-K, and any amendments to these reports. These reports are provided as
soon as reasonably practicable after such reports are electronically filed with
or furnished to the Securities and Exchange Commission.

FINANCIAL INFORMATION ABOUT INDUSTRY SEGMENTS

The information required by this item is provided in Note 20, Industry Segment
Information, in the Notes to Financial Statements.

NARRATIVE DESCRIPTION OF BUSINESS

- - OIL AND GAS OPERATIONS

GENERAL: Energen's oil and gas operations focus on increasing
production and adding proved reserves through the acquisition and
development of oil and gas properties. To a lesser extent, Energen
Resources explores for and develops new reservoirs, primarily in areas
in which it has an operating presence. Substantially all gas production
and all oil and natural gas liquids production is sold to third
parties. Energen Resources also provides operating services in the
Black Warrior Basin in Alabama for its partners and third parties.
These services include overall project management and day-to-day
decision-making relative to project operations.

At the end of 2002, Energen Resources' inventory of proved oil and gas
reserves totaled 1,262.9 billion cubic feet equivalent (Bcfe).
Substantially all of the company's approximately 1.3 trillion cubic
feet equivalent of reserves are located in the San Juan Basin in New
Mexico, the Black Warrior Basin in Alabama, the Permian Basin in west
Texas, and the north Louisiana/east Texas region. Approximately 82
percent of Energen Resources' year-end reserves are proved developed
reserves. Energen Resources reserves are long-lived, with a year-end
reserves-to-production ratio of 16. Natural gas represents
approximately 64 percent of Energen Resources' proved reserves, with
oil representing approximately 24 percent and natural gas liquids
comprising the balance.

GROWTH STRATEGY: Energen has operated for more than seven years under a
strategy to grow its oil and gas operations. Since the end of fiscal
year 1995, Energen Resources has invested approximately $715 million in
property acquisitions, $435 million in related development, and $90
million in exploration and associated development. Energen Resources'
capital investment for oil and gas activities over the five-year period
ending December 31, 2007, is currently expected to approximate $835
million.

Energen Resources' approach to the oil and gas business calls for the
company to pursue onshore North American property acquisitions which
offer proved undeveloped (PUD) and/or behind-pipe reserves as well as
operational enhancement potential. Energen Resources prefers operated
natural gas properties with long-lived reserves and multiple pay-zone
opportunities; however, Energen Resources does not preclude possible
acquisitions of properties that otherwise meet its investment
requirements.

Following an acquisition, Energen Resources focuses on increasing
production and reserves through development of the properties' PUD and
behind-pipe reserve potential as well as engaging in other development
activities. These activities include development well drilling,
behind-pipe recompletions, pay-adds, workovers, secondary recovery and
operational enhancements. Energen Resources prefers to operate its
properties in order to better control the nature and pace of
development activities.

Energen Resources' development activities can result in the addition of
new proved reserves and can serve to reclassify proved undeveloped
reserves to proved developed reserves. Proved reserve disclosures are
provided annually, although changes to reserve classifications occur
throughout the year. Accordingly, additions of new reserves from
development activities can occur throughout the year and may result
from numerous factors including, but not limited to, regulatory
approvals for drilling unit downspacing which increase the number of
available drilling locations; changes in the economic or operating
environments which allow previously uneconomic locations to be added;
technological advances which make reserve locations available for

4


development; successful development of existing PUD locations which
reclassify adjacent probable locations to PUD locations; increased
knowledge of field geology and engineering parameters relative to oil
and gas reservoirs; and changes in management's intent to develop
certain opportunities.

Since the end of fiscal year 1999, the Company's development efforts
have added approximately 298 Bcfe of proved reserves from the drilling
of approximately 540 gross development wells and 408 well recompletions
and pay-adds. In 2002, Energen Resources' successful development wells
and other activities added approximately 162 Bcfe of proved reserves.
The company drilled 232 gross development wells, performed some 95 well
recompletions and pay-adds, and conducted other operational
enhancements. Energen Resources' production from continuing operations
totaled 77.4 Bcfe in 2002 and is estimated to total 85 Bcfe in 2003,
including 82.4 Bcfe of estimated production from proved reserves owned
at December 31, 2002.

Most of Energen Resources' coalbed methane production generated
nonconventional fuels tax credits through December 31, 2002. In 2002,
Energen Resources' nonconventional fuels tax credits totaled $14.2
million. Nonconventional fuels tax credits are no longer generated due
to tax law changes effective December 31, 2002. To mitigate the effects
on corporate earnings in 2003, Energen Resources has replaced a portion
of the tax credit benefit with long-term, revenue-generating property
acquisitions and their related development activities and has increased
the number of available drilling locations through unit downspacing in
the Black Warrior Basin.

RISK MANAGEMENT: Energen Resources attempts to lower the risk
associated with its oil and natural gas business. A key component of
the company's efforts to manage risk is its acquisition versus
exploration orientation and its preference for long-lived reserves. In
pursuing an acquisition, Energen Resources primarily uses in its
evaluation models the then-current oil and gas futures prices, the
prevailing swap curve and, for the longer-term, its own pricing
assumptions. After a purchase, Energen Resources may use futures, swaps
and/or fixed-price contracts to hedge commodity prices on flowing
production for up to 36 months to help protect targeted returns from
price volatility. On an on-going basis, Energen Resources may hedge up
to 80 percent of its annual production in any given year depending on
its pricing outlook.

The Company adopted Statement of Financial Accounting Standards (SFAS)
No. 133 (subsequently amended by SFAS Nos. 137 and 138), "Accounting
for Derivative Instruments and Hedging Activities," on October 1, 2000.
This statement 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 Company is required to measure the effectiveness
of the hedge, or the degree that the gain (loss) for the hedging
instrument offsets the loss (gain) on the hedged item, at each
reporting period. The effective portion of the gain or loss on the
derivative instrument is recognized in other comprehensive income as a
component of equity and subsequently reclassified into earnings when
the forecasted transaction affects earnings. The ineffective portion of
a derivative's change in fair value is required to be recognized in
earnings immediately. Derivatives that do not qualify for hedge
treatment under SFAS No. 133 must be recorded at fair value with gains
or losses recognized in earnings in the period of change.

The Company periodically enters into derivative transactions that do
not qualify for cash flow hedge accounting but are considered by
management to represent valid economic hedges and are accounted for as
mark-to-market transactions. These economic hedges may include, but are
not limited to, basis hedges without a corresponding New York
Mercantile Exchange (NYMEX) hedge, put options and hedges on
non-operated or other properties for which all of the necessary
information to qualify for cash flow hedge accounting is either not
readily available or subject to change.

See the Forward-Looking Statement and Risk in Item 7, Management's
Discussion and Analysis of Financial Condition and Results of
Operations, for further discussion with respect to price and other
risk.

ENVIRONMENTAL MATTERS: Energen Resources is subject to various
environmental regulations. Management believes that Energen Resources
is in compliance with currently applicable standards of the
environmental agencies to which it is subject and that potential
environmental liabilities are minimal. Also, to the extent that


5


Energen Resources has operating agreements with various joint venture
partners, environmental costs would be shared proportionately.

OTHER: For a discussion of risks inherent in the Company's businesses,
see Item 7, Management's Discussion and Analysis of Financial Condition
and Results of Operations.


- - NATURAL GAS DISTRIBUTION

GENERAL: Alagasco is the largest natural gas distribution utility in
the state of Alabama. Alagasco purchases natural gas through interstate
and intrastate marketers and suppliers and distributes the purchased
gas through its distribution facilities for sale to residential,
commercial and industrial customers and other end-users of natural gas.
Alagasco also provides transportation services to industrial and
commercial customers located on its distribution system. These
transportation customers, using Alagasco as their agent or acting on
their own, purchase gas directly from producers, marketers or suppliers
and arrange for delivery of the gas into the Alagasco distribution
system. Alagasco charges a fee to transport such customer-owned gas
through its distribution system to the customers' facilities.

Alagasco's service territory is located in central and parts of north
Alabama and includes approximately 188 cities and communities in 28
counties. The aggregate population of the counties served by Alagasco
is estimated to be 2.3 million. Among the cities served by Alagasco are
Birmingham, the center of the largest metropolitan area in Alabama, and
Montgomery, the state capital. During 2002, Alagasco served an average
of 425,630 residential customers and 35,601 commercial, industrial and
transportation customers. The Alagasco distribution system includes
approximately 9,723 miles of main and more than 11,395 miles of service
lines, odorization and regulation facilities, and customer meters.

APSC REGULATION: As an Alabama utility, Alagasco is subject to
regulation by the Alabama Public Service Commission (APSC) which, in
1983, established the Rate Stabilization and Equalization (RSE)
rate-setting process. RSE was extended in 2002, 1996, 1990, 1987 and
1985. On June 10, 2002, the APSC extended RSE for a six-year period,
through January 1, 2008. Under the APSC order, Alagasco's allowed range
of return on average equity remains 13.15 percent to 13.65 percent
throughout the term of the order, subject to change in the event that
the Commission, following a generic rate of return hearing, adjusts the
returns on equity of all major energy utilities operating under a
similar methodology. Alagasco is on a September 30 fiscal year for
rate-setting purposes (rate year).

Under RSE as extended, 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. 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. RSE limits the utility's equity upon which a return is
permitted to 60 percent of total capitalization and provides for
certain cost control measures designed to monitor Alagasco's operations
and maintenance (O&M) expense. Under the inflation-based cost control
measurement established by the APSC, if the percentage change in O&M
expense per customer falls within a range of 1.25 points above or below
the percentage change in the Consumer Price Index For All Urban
Consumers (index range), no adjustment is required. If the change in
O&M expense per customer exceeds the index range, three-quarters of the
difference is returned to customers. To the extent the change is less
than the index range, the utility benefits by one-half of the
difference through future rate adjustments.

The temperature adjustment rider to Alagasco's rate tariff, approved by
the APSC in 1990, was designed to mitigate the earnings impact of
variances from normal temperatures. Alagasco performs this real-time
temperature adjustment calculation monthly, and the adjustments to
customers' bills are made in the same billing cycle in which the
weather variation occurs. Substantially all the customers to whom the
temperature adjustment applies are residential, small commercial and
small industrial. Alagasco's rate schedules for natural gas
distribution charges contain a Gas Supply Adjustment (GSA) rider that
permits the pass-through to customers of changes in the cost of gas
supply.


6


The APSC approved an Enhanced Stability Reserve (ESR) beginning October
1997, with an approved maximum funding level of $4 million, to which
Alagasco may charge the full amount of: (1) extraordinary O&M expenses
resulting from force majeure events such as storms, severe weather, and
outages, when one or a combination of two such events results in more
than $200,000 of additional O&M expense during a rate year; or (2)
individual industrial and commercial customer revenue losses that
exceed $250,000 during the rate year, if such losses cause Alagasco's
return on equity to fall below 13.15 percent. Following a year in which
a charge against the ESR is made, the APSC provides for accretions to
the ESR in an amount of no more than $40,000 monthly until the maximum
funding level is achieved.

GAS SUPPLY: Alagasco's distribution system is connected to and has firm
transportation contracts with two major interstate pipeline systems -
Southern Natural Gas Company (Southern) and Transcontinental Gas Pipe
Line Corporation (Transco). On Southern's system, Alagasco has 251,679
thousand cubic feet (Mcfd) of No-Notice Firm Transportation service
through October 31, 2008, and 134,332 Mcfd of Firm Transporation
service, of which 40,000 Mcfd expires April 30, 2005, 1,959 Mcfd
expires October 31, 2005 and the balance expires October 31, 2008. The
Transco Firm Transportation contract, which expires October 31, 2005,
provides for up to 100,000 Mcfd. As a result, Alagasco has a peak day
firm interstate pipeline transportation capacity of 486,011 Mcfd.
Alagasco has 12,464,074 Mcf of storage capacity on Southern's system,
with a maximum withdrawal rate of 251,679 Mcfd from storage and a
maximum injection rate of 95,878 Mcfd to storage. Alagasco also
operates two liquified natural gas (LNG) facilities used to meet peak
demand.

Alagasco purchases gas from various gas producers and marketers,
including affiliates of Southern, and from certain intrastate producers
and marketers. Alagasco has contracts in place to purchase up to
233,230 Mcfd of firm supply, of which 234,332 Mcfd is supported by firm
transportation on the Transco and Southern systems and approximately
21,450 Mcfd is purchased at the city gate under intrastate firm supply
contracts. These firm supply volumes along with Alagasco's maximum
withdrawal from storage of 251,679 Mcfd and LNG peak-shaving capacity
of 200,000 Mcfd, give Alagasco a peak day firm supply of 684,909 Mcfd.
Alagasco also utilizes the Southern pipeline systems to access spot
market gas in order to supplement its firm system supply and serve its
industrial and large commercial transportation customers. Deliveries of
sales and transportation gas totaled 97,840 million cubic feet in 2002.

COMPETITION AND RATE FLEXIBILITY: The price of natural gas is a
significant competitive factor in Alagasco's service territory,
particularly among large commercial and industrial transportation
customers. Propane, coal and fuel oil are readily available, and many
industrial customers have the capability to switch to alternate fuels
and/or alternate sources of gas. In the residential and small
commercial and industrial markets, electricity is the principal
competitor. With the support of the APSC, Alagasco has implemented a
variety of flexible rate strategies to help it compete for the large
customers' gas load in the deregulated marketplace. Rate flexibility
remains critical as the utility faces competition for the large
customer load. To date, the utility has been effective in utilizing its
flexible rate strategies to minimize bypass and price-based switching
to alternate fuels and alternate sources of gas.

In 1994 Alagasco implemented the P Rate in response to the competitive
challenge of interstate pipeline capacity release. Under this tariff
provision, Alagasco releases much of its excess pipeline capacity and
repurchases it as agent for its transportation customers under 12 month
contracts. The transportation customers benefit from lower pipeline
costs. Alagasco's core market customers benefit, as well, since the
utility uses the revenues received from the P Rate to decrease gas
costs for its residential and small commercial and industrial
customers. In 2002, approximately 300 of Alagasco's transportation
customers utilized the P Rate, and the resulting reduction in core
market gas costs totaled approximately $9.1 million.

The Competitive Fuel Clause (CFC) and Transportation Tariff also have
been important to Alagasco's ability to compete effectively for
customer load in its service territory. The CFC allows Alagasco to
adjust large customer rates on a case-by-case basis to compete with
alternate fuels and alternate sources of gas. The GSA rider to
Alagasco's tariff allows the Company to recover the reduction in
charges allowed under the CFC because the retention of any customer,
particularly large commercial and industrial transportation customers,
benefits all customers by recovering a portion of the system's fixed
costs. The Transportation Tariff allows Alagasco to


7


transport gas for customers, rather than buy and resell it to them, and
is based on Alagasco's sales profit margin so that operating margins
are unaffected. During 2002 substantially all of Alagasco's large
commercial and industrial customer deliveries were the transportation
of customer-owned gas. In addition, Alagasco served as gas purchasing
agent for approximately 99 percent of its transportation customers.
Alagasco also uses long-term special contracts as a vehicle for
retaining large customer load. At the end of 2002, 49 of the utility's
largest commercial and industrial transportation customers were under
special contracts of varying lengths.

Natural gas service available to Alagasco customers falls into two
broad categories: interruptible and firm. Interruptible service
contractually is subject to interruption by Alagasco for various
reasons; the most common occurrence is curtailment of industrial
customers during periods of peak core market heating demand.
Interruptible service typically is provided to large commercial and
industrial transportation customers who can reduce their gas
consumption by adjusting production schedules or by switching to
alternate fuels for the duration of the service interruption. More
expensive firm service, on the other hand, generally is not subject to
interruption and is provided to residential and small commercial and
industrial customers; these core market customers depend on natural gas
primarily for space heating.

GROWTH: Customer growth presents a major challenge for Alagasco, given
its mature, slow-growth service area. In 2002, Alagasco's average
number of customers declined slightly due to the previous year's high
gas costs and industrial load loss resulting from an economic slowdown.
The utility penetrated 86 percent of the new single-family housing
market in its service area and 18 percent of the new multi-family
housing market. For 2003, Alagasco will concentrate on maintaining its
current penetration levels in the residential new construction market
while increasing its focus on generating additional revenue in the
small and large commercial and industrial market segments.

A vehicle for supplementing Alagasco's normal growth continues to be
Alagasco's municipal acquisition program. Since 1985, Alagasco has
acquired 23 municipally owned systems adding more than 43,000 customers
through initial system purchases and subsequent customer additions.
Approximately 75 municipal systems remain in Alabama. Alagasco
continues to pursue the purchase of municipal gas systems, and company
management believes that such acquisitions could offer future growth
opportunities.

SEASONALITY: Alagasco's gas distribution business is highly seasonal
since a material portion of the utility's total sales and delivery
volumes is to space heating customers. Alagasco's rate tariff includes
a temperature adjustment rider primarily for residential, small
commercial and small industrial customers which substantially mitigates
the effect of departures from normal temperature on Alagasco's
earnings. The calculation is performed monthly, and adjustments are
made to customers' bills in the actual month the weather variation
occurs.

ENVIRONMENTAL MATTERS: Alagasco is in the chain of title of eight
former manufactured gas plant sites and five manufactured gas
distribution sites. It still owns four of the plant sites and one of
the distribution sites. 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 of any associated costs will not materially affect the
Company's results of its operations or financial condition.

Results of Operations as set forth in Item 7 of Part II of this Form

The Company has 1,533 employees; Alagasco employs 1,259; Energen Resources
employs 261; and Energen's other subsidiaries employ 13. The Company believes
that its relations with employees are good.

The properties of Alagasco consist primarily of its gas distribution system,
which includes more than 9,723 miles of main, more than 11,395 miles of service
lines, odorization and regulation facilities, and customer meters. Alagasco also
has two LNG facilities, seven division offices, four payment centers, five
district offices, nine service centers, and other related property and
equipment, some of which are leased by Alagasco. For a further description of
Alagasco's properties, see discussion under Item 1-Business.

ITEM 3. LEGAL PROCEEDINGS

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 specific relief. Based upon information
presently available and in light of available legal and other defenses,
contingent liabilities arising from threatened and pending litigation are not
considered material in relation to the respective financial positions of Energen
and its affiliates. It should be noted, however, that Energen and its affiliates
conduct business in Alabama and other jurisdictions in which the magnitude and
frequency of punitive damage awards may bear little or no relation to
culpability or actual damages thus making it difficult to predict litigation
results.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

CRITICAL ACCOUNTING POLICIES

The Company's consolidated financial statements are prepared in accordance with
accounting principles generally accepted in the United States of America.
Management has identified the following critical accounting policies in the
application of existing accounting standards or in the implementation of new
standards that involve significant judgements and estimates by the Company:

OIL AND GAS OPERATIONS
ACCOUNTING FOR NATURAL GAS AND OIL PRODUCING ACTIVITIES AND RELATED RESERVES:
The Company utilizes the successful efforts method of accounting for its natural
gas and oil producing activities. Under this accounting method, acquisition and
development costs of proved properties are capitalized and amortized on a
units-of-production basis over the remaining life of total proved and proved
developed reserves.

Estimates of physical quantities of oil and gas reserves are determined by
Company engineers and, in some cases, by third-party experts. Proved oil and gas
reserves are the estimated quantities of crude oil, natural gas and natural gas
liquids that geological and engineering data demonstrate with reasonable
certainty to be recoverable in future years from known reservoirs under existing
economic and operating conditions. Accordingly, these estimates do not include
probable or possible reserves. Estimated oil and gas reserves are based on
currently available reservoir data and are subject to future revision. The
Company's production of undeveloped reserves require the installation or
completion of related infrastructure facilities such as pipelines and the
drilling of development wells.

Changes in oil and gas prices, operating costs and expected performance from the
properties will result in a revision to the amount of estimated reserves held by
the Company. If reserves are revised upward, earnings could be affected due to
lower depreciation and depletion expense per unit of production. Likewise, if
reserves are revised downward, earnings could be affected due to higher
depreciation and depletion expenses or due to an immediate writedown of the
property's book value if an impairment is warranted. The table below reflects
the estimated effect on depreciation and depletion expense for 2003 of changes
in oil and gas reserve quantities from the reported amounts at December 31,
2002.



Percentage Change in Oil & Gas Reserves
From Reported Reserves as of December 31, 2002
(dollars in thousands) +10% +5% -5% -10%
------- ------- ------- -------

Estimated change in depreciation expense for
the year ended December 31, 2003, net of tax $(4,300) $(2,100) $ 2,400 $ 5,200
------- ------- ------- -------


ASSET IMPAIRMENTS: Oil and gas developed and undeveloped properties periodically
are assessed for possible impairment, generally on a field-by-field basis, using
the estimated undiscounted future cash flows of each field. Impairment losses
are recognized when the estimated undiscounted future cash flows are less than
the current net book values of the properties in a field. The Company monitors
its oil and gas properties as well as the market and business environments in
which it operates and makes assessments about events that could result in
potential impairment issues. Such potential events may include, but are not
limited to, substantial commodity price declines, unanticipated increased
operating costs, and lower-than-expected production performance from the
properties. If a material event occurs, Energen Resources makes an estimate of
undiscounted future cash flows to determine whether the asset is impaired. If
the asset is impaired, the Company will record an impairment loss for the
difference between the net book value of the properties and the fair value of
the properties. The fair value of the properties typically is estimated using
discounted cash flow.

Cash flow and fair value estimates require Energen Resources to make projections
and assumptions for pricing, demand, competition, operating costs, legal and
regulatory issues, discount rates and other factors for many years into the
future. These variables can, and often do, differ from the estimate and can have
a positive or negative


14


impact on the Company's need for impairment or of the amount of impairment. In
addition, further changes in the economic and business environment can impact
the Company's original and ongoing assessments of potential impairment.

NATURAL GAS DISTRIBUTION
REGULATED OPERATIONS: Alagasco applies SFAS No. 71, "Accounting for the Effects
of Certain Types of Regulation," to its regulated operations. This standard
requires a cost to be capitalized as a regulatory asset that otherwise would be
charged to expense if it is probable that the cost is recoverable in the future
through regulated rates. Likewise, if current recovery is provided for a cost
that will be incurred in the future, SFAS No. 71 requires the cost to be
recognized as a regulatory liability. The Company anticipates SFAS No. 71 will
continue as the applicable accounting standard for its regulated operations.
Alagasco's rate setting methodology, Rate Stabilization and Equalization, has
been in effect since 1983.

CONSOLIDATED
EMPLOYEE BENEFIT PLANS: Determining the Company's obligations to employees under
its defined benefit pension plan requires the use of estimates. The calculation
of the liability related to the Company's defined benefit pension plan requires
assumptions regarding the appropriate weighted average discount rate, estimated
rate of increase in the compensation level of its employee base and the expected
long-term rate of return on the plans' assets. The selection and use of such
assumptions affects the amount of expense recorded in the Company's financial
statements related to its defined benefit pension plan. The discount rate for
pension cost purposes is the rate at which pension obligations could be
effectively settled. At December 31, 2002 the discount rate used for actuarial
purposes was 6.75 percent. A hypothetical basis point change in the discount
rate would impact total pension expense by approximately $560,000. The assumed
rate of return on assets is the weighted average of expected long-term asset
assumptions. At December 31, 2002, the return on assets used for actuarial
purposes was 9 percent. A hypothetical 25 basis point change in the return on
assets would impact total pension expense by approximately $245,000.

CHANGE IN YEAR END

On December 5, 2001, the Board of Directors of the Company approved a change in
the Company's fiscal year end from September 30 to December 31, effective
January 1, 2002. A transition report was filed on Form 10-Q for the period
October 1, 2001 to December 31, 2001. Alagasco will continue on a September 30
fiscal year for rate-setting purposes (rate year) and will report on a calendar
year for the Securities and Exchange Commission and all other financial
accounting reporting purposes.

RESULTS OF OPERATIONS

CONSOLIDATED NET INCOME
Energen Corporation's net income for the year ended December 31, 2002 totaled
$68.6 million, or $2.03 per diluted share compared to fiscal year ended
September 30, 2001 net income of $67.9 million, or $2.18 per diluted share. This
7 percent decrease in earnings per diluted share (EPS) reflects an increase in
the number of shares outstanding related to the acquisition of oil and gas
properties in the Permian Basin in April 2002. Energen Resources Corporation,
Energen's oil and gas subsidiary, had a slight decrease in earnings for the 12
months ended December 31, 2002, as compared with the 12 months ended September
30, 2001. Alabama Gas Corporation (Alagasco), Energen's utility subsidiary,
generated a 6 percent increase in net income in the same period comparisons. For
the 12 months ended September 30, 2000, Energen reported earnings of $53
million, or $1.75 per diluted share.

2002 VS 2001: For the year ended December 31, 2002, Energen Resources' net
income totaled $41.2 million as compared with $42.6 million for the 12 months
ended September 30, 2001. Net income in the current year included a non-cash
benefit of $5.7 million after-tax ($0.17 per diluted share) associated with its
previous hedge position with Enron North America Corp. (Enron) and a one-time
charge of $2.2 million after-tax ($0.07 per diluted share), reflecting the
cumulative effect on prior years of the adoption of SFAS No. 143, "Accounting
for Asset Retirement Obligations." Energen Resources' income from continuing
operations in 2002 totaled $43.2 million as compared with $40.8 million in
fiscal 2001, primarily due to a 15.8 percent increase in production volumes
related to an acquisition of oil properties in the Permian Basin in April 2002.
The primary negative influences on income from


15


operations were increased lease operating expense and increased depreciation,
depletion and amortization (DD&A) expense.

Alagasco's earnings increased to $27.6 million in 2002 from $26 million in
fiscal year 2001 as a result of the utility having increased earnings on a
higher level of equity. Alagasco achieved a return on average equity (ROE) of
12.3 percent in both 2002 and 2001.

2001 VS 2000: Energen Resources' net income in fiscal 2001 rose 55.2 percent to
$42.6 million. Energen Resources' income from continuing operations in fiscal
2001 totaled $40.8 million as compared with $26.9 million in fiscal 2000,
primarily due to a 23.3 percent increase in realized sales prices for natural
gas, oil and natural gas liquids production. The significantly higher realized
commodity prices more than compensated for the negative impact of increased
lease operating expense and a 1.9 Bcfe production decrease. Earnings in fiscal
year 2000 were negatively affected by a $2.2 million ($0.07 per diluted share)
after-tax writedown under SFAS No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to be Disposed of," for certain oil
and gas properties resulting from a downward reserve revision.

Alagasco's earnings declined 1.2 percent from $26.3 million in fiscal 2000 to
$26 million in fiscal year 2001. This slight decrease in income was primarily a
result of increased bad debt expense from significantly colder weather and
higher natural gas prices during the fiscal 2001 winter as well as industrial
load loss resulting from an economic slowdown. Alagasco achieved a return on
average equity (ROE) of 12.3 percent in 2001 as compared to 13.4 percent in
2000.

THREE MONTHS ENDED DECEMBER 31, 2001 VS THREE MONTHS ENDED DECEMBER 31, 2000:
Energen's net income totaled $3.7 million ($0.12 per diluted share) for the
three months ended December 31, 2001, compared to net income of $13.7 million
($0.44 per diluted share) recorded in the same period of 2000. Energen Resources
realized net income from continuing operations of $1.1 million in the December
31, 2001 transition quarter as compared with $9.3 million in the same quarter in
the previous year largely due to a one-time non-cash write-off of $5.5 million
after-tax ($0.17 per diluted share) associated with its hedge position with
Enron. Also negatively impacting net income in the transition quarter were
increased DD&A expense, a $1.7 million writedown on property held for sale and
lower natural gas liquids prices. Energen's natural gas utility, Alagasco,
reported net income of $2.7 million in the transition quarter as compared to $4
million in the same period in the previous year primarily due to increased bad
debt expense as well as a decline in cycle and industrial gas usage.

OPERATING INCOME
Consolidated operating income in 2002, 2001 and 2000 totaled $136 million, $121
million and $95 million, respectively. This significant growth in operating
income was influenced by strong financial performance from Energen Resources
under Energen's diversified growth strategy, implemented in fiscal 1996.
Alagasco also contributed to this growth in operating income consistent with an
increase in the level of equity upon which it has been able to earn a return.

OIL AND GAS OPERATIONS: Revenues from oil and gas operations rose significantly
in the current year largely as a result of increased production volumes related
to the acquisition of oil properties in the Permian Basin. During 2002,
production from continuing operations increased 15.8 percent to 77.4 Bcfe.
Natural gas production increased 4.2 percent to 47.8 Bcf and oil volumes rose
55.5 percent to 3,139 MBbl. Production of natural gas liquids increased 21.3
percent to 1,792 MBbl. Including the non-cash benefit from the former Enron
hedges, realized gas prices rose 2.3 percent to $3.16 per Mcf, while realized
oil prices increased 1.1 percent to $24.03 per barrel. Natural gas liquids
prices fell 27.6 percent to an average price of $12.75 per barrel.

In fiscal 2001, revenues from oil and gas continuing operations increased
largely as a result of significantly higher commodity prices as compared to the
previous fiscal year. Realized gas prices rose 24.1 percent to $3.09 per Mcf,
while realized oil prices increased 29.7 percent to $23.78 per barrel. Natural
gas liquids prices increased 9.7 percent to an average price of $17.61 per
barrel. During 2001, production from continuing operations declined slightly to
66.8 Bcfe as natural gas production decreased 3.4 percent to 45.8 Bcf and oil
volumes declined 5.7 percent to 2,019 MBbl. Production of natural gas liquids
increased 4.7 percent to 1,477 MBbl. This 1.9 Bcfe


16


decrease in production largely was due to normal production declines in Energen
Resources' coalbed methane and south Louisiana properties. Drilling in the San
Juan and Permian basins and in the north Louisiana/east Texas area served to
replace aggregate production in these areas.

Coalbed methane operating fees are calculated as a percentage of net proceeds on
certain properties, as defined by the related operating agreements, and vary
with changes in natural gas prices, production volumes and operating expenses.
Revenues from operating fees were $4.8 million, $7.6 million and $4.3 million in
2002, 2001 and 2000, respectively.

Energen Resources may, in the ordinary course of business, be involved in the
sale of developed or undeveloped properties. With respect to developed
properties, sales may occur as a result of, but not limited to, disposing of
non-strategic or marginal assets and accepting offers where the buyer gives
greater value to a property than does Energen Resources. The Company is required
to reflect gains and losses on the dispositions of these assets, the writedown
of certain properties held-for-sale, and income or loss from the operations of
the associated held-for-sale properties as discontinued operations under the
provisions of SFAS No. 144, which was adopted as of January 1, 2002. Energen
Resources recorded in 2002 a pre-tax gain of $0.9 million in total income from
discontinued operations from the sale of properties and adjustments to the fair
value of properties being held-for-sale. In 2001, prior to the adoption of SFAS
No. 144, Energen Resources recorded in operating revenues a net pre-tax gain
from the sale of properties and adjustments to the fair value of properties held
for sale of $0.8 million. Pre-tax gains from the sale of properties of $1.1
million were recorded in operating revenues in 2000.

Operations and maintenance (O&M) expense increased $10.3 million and $9.9
million in 2002 and 2001, respectively. Lease operating expense in 2002 rose
$7.6 million primarily due to the acquisition of oil and gas properties. In
2001, lease operating expense increased by $9.2 million largely due to
significantly higher operational costs driven by market conditions resulting
from increased commodity costs. In the current year, administrative expense
increased $3.5 million primarily due to labor related costs and additional cost
related to the property acquisition. Administrative expense increased $1.4
million in 2001. Exploration expense decreased $0.6 million in 2002 and $0.7
million in 2001, primarily due to reduced exploratory efforts.

DD&A expense increased $17.6 million in 2002 largely due to increased production
volumes and increased DD&A rates. In 2001, DD&A expense decreased $2.4 million
primarily due to lower production volumes and additional pre-tax DD&A expense of
$3.5 million recorded in 2000 to adjust the carrying amount of certain
properties to their


17


fair value based on expected future discounted cash flows (see Note 12). The
average depletion rate was $0.90 per Mcfe in 2002 as compared to $0.79 per Mcfe
in the prior year.

Energen Resources' expense for taxes other than income primarily reflected
production-related taxes. Energen Resources recorded severance taxes for 2002 of
$18.9 million. Severance taxes in 2001 were $23.9 million as a result of
increased commodity prices. In 2000, severance taxes were $17.3 million.

OIL AND GAS OPERATIONS - TRANSITION PERIOD: Revenues from oil and gas continuing
operations declined 9.8 percent to $49.5 million for the three months ended
December 31, 2001, largely as a result of lower natural gas liquids prices. In
the transition quarter, realized gas prices increased 8.4 percent to $2.97 per
Mcf, while realized oil prices rose 7.8 percent to $24.19 per barrel. Natural
gas liquids prices decreased 51.4 percent to an average price of $10.07 per
barrel.

Natural gas production in the transition quarter increased slightly to 11.9 Bcf,
while oil volumes decreased slightly to 512 MBbl. Natural gas liquids production
increased 13.9 percent to 450 MBbl. Natural gas comprised nearly 70 percent of
Energen Resources' production in the transition quarter.

Prior to the adoption of SFAS No. 144, Energen Resources recorded in operating
revenues a pre-tax loss of $3.4 million for the current transition quarter from
the sale of properties and adjustments to the fair value of properties
held-for-sale as compared to a pre-tax gain of $0.8 million in the prior year
quarter on the sale of various properties.

O&M expense increased $8.6 million for the transition quarter ended December 31,
2001, largely due to the one-time non-cash writedown of $8.7 million pre-tax
associated with Energen Resources' hedge position with Enron. Lease operating
expenses increased by $0.4 million for the transition quarter while exploration
expense remained relatively stable.

Energen Resources' DD&A expense for the period rose $4.5 million primarily
driven by the impact of market declines in commodity prices. The average
depletion rate for the transition quarter was $0.91 as compared to $0.67 for the
same period in the previous year.


18



Energen Resources' expense for taxes other than income taxes primarily reflected
production-related taxes that were $3.3 million lower in the transition quarter
primarily as a result of the significantly decreased commodity market prices.

NATURAL GAS DISTRIBUTION: As discussed more fully in Note 2, Alagasco is subject
to regulation by the Alabama Public Service Commission (APSC). On June 10, 2002,
the APSC issued an order to extend the Company's rate-setting mechanism. Under
the terms of that extension, RSE will continue after January 1, 2008, unless,
after notice to the Company and a hearing, the Commission votes to either modify
or discontinue its operation.

Alagasco generates revenues through the sale and transportation of natural gas.
The transportation rate does not contain an amount representing the cost of gas,
and Alagasco's rate structure allows similar margins on transportation and sales
gas. Weather can cause variations in space heating revenues, but operating
margins essentially remain unaffected due to a real-time temperature adjustment
mechanism that allows Alagasco to adjust customer bills monthly to reflect
changes in usage due to departures from normal temperatures. The temperature
adjustment applies to residential, small commercial and small industrial
customers.

Alagasco's natural gas and transportation sales revenues totaled $424.4 million,
$553.9 million and $366.2 million in 2002, 2001 and 2000, respectively. Lower
commodity gas costs and weather that was 13.1 percent warmer than in the prior
year contributed to the decrease in sales revenue in the current year. Sales
revenue in fiscal 2001 rose due to significantly higher commodity gas costs as
well as weather that was 29.9 percent colder than in fiscal year 2000.

In the current year, residential sales volumes decreased 15.1 percent primarily
due to the impact of warmer weather on throughput. Small commercial and
industrial volumes, also sensitive to weather, decreased 15.8 percent.
Transportation volumes rose 10.5 percent, due to the previous period's
significantly higher natural gas prices and a general economic weakness. During
2001, significantly colder weather in Alagasco's service territory caused a 19.2
percent increase in residential sales volumes and a 16.2 percent increase in
small commercial and industrial sales volumes. Transportation volumes decreased
23.5 percent, primarily due to the prior-year closing of a steel manufacturing
plant and reduced consumption resulting from an economic downturn during the
year.

In 2002, significantly lower commodity gas costs along with decreased purchased
volumes due to warmer weather resulted in a 41.9 percent decrease in cost of
gas. Higher commodity cost of gas, including record high prices in fiscal year
2001, along with increased purchased volumes resulting from colder weather
generated a 111.5 percent increase in cost of gas for fiscal year 2001.

O&M expense at the utility increased 3.1 percent in 2002 primarily due to higher
insurance and labor-related costs partially offset by reduced bad debt expense
and marketing costs. In fiscal 2001, O&M expense increased 1.5 percent primarily
as a result of increased bad debt expense and insurance costs largely offset by
reduced marketing and labor-related costs. The increase in O&M expense per
customer was above the inflation-based Cost Control Measurement (CCM)
established by the APSC as part of the utility's rate-setting mechanism, for the
rate year ended September 30, 2002; as a result, three quarters of the
difference, or $0.3 million pre-tax, was returned to the customers through RSE
(see Note 2). In 2001 and 2000, the increase in O&M expense on a per-customer
basis fell within the CCM.

Consistent with growth in the utility's depreciable base, depreciation expense
rose 8.9 percent in 2002 and 7.8 percent in 2001. Alagasco's expense for taxes
other than income primarily reflects 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.

NATURAL GAS DISTRIBUTION - TRANSITION PERIOD: Natural gas distribution revenues
decreased $22.4 million for the transition quarter ended December 31, 2001,
largely due to a decrease in the commodity cost of gas as well as to a decrease
in weather-related sales volumes and gas usage volumes. For the quarter, weather
that was 30.1 percent warmer than the same period last year contributed to a
29.1 percent decrease in residential sales volumes and a 34.3 percent decrease
in small commercial and industrial customer sales volumes. Transportation
volumes decreased 6.3 percent primarily due to reduced consumption resulting
from a general economic weakness in the transition period. Lower commodity gas
prices along with decreased gas purchase volumes contributed to a 32.5 percent
decrease in cost of gas for the quarter.

O&M expense increased 3.2 percent in the transition quarter primarily due to
increased bad debt expense partially offset by reduced labor-related and
marketing costs. A 7.9 percent increase in depreciation expense in the
three-months ended December 31, 2001 primarily was due to normal growth of the
utility's distribution system. 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
CONSOLIDATED: Interest expense in 2002 increased $1.6 million and was influenced
by increased short-term debt at Energen, primarily related to Energen Resources'
acquisition of Permian Basin properties in April 2002, as well as Alagasco's
issuance of $40 million of 6.25% Notes and $35 million of 6.75% Notes in August
2001 (the Notes). Fiscal 2001 interest expense increased $4.3 million primarily
due to $150 million of medium term notes (MTNs) issued by Energen in December
2000 and, in part, from the issuance of the Notes. The average daily outstanding
balance under short-term credit facilities was $85.6 million in 2002. The
average daily outstanding balance under short-term credit facilities was $80.7
million in fiscal year 2001 as compared to $146.8 million in fiscal year 2000.

The Company's effective tax rates in 2002, 2001 and 2000 were lower than
statutory federal tax rates primarily due to the recognition of nonconventional
fuels tax credits and the amortization of investment tax credits.
Nonconventional fuels tax credits were generated annually on qualified
production through December 31, 2002.


20


Income tax expense increased in 2002 and 2001 primarily due to higher pre-tax
income. The Company recognized $14.2 million, $13.6 million and $14.4 million in
nonconventional fuels tax credits in 2002, 2001 and 2000, respectively. The
nonconventional fuels tax credits are no longer generated effective December 31,
2002, due to changes in the tax law. As of December 31, 2002, the amount of
minimum tax credit that has been previously recognized and can be carried
forward indefinitely to reduce future regular tax liability is $64.8 million.

TRANSITION PERIOD: Interest expense for the Company increased $0.4 million for
the transition quarter. Influencing the increase in interest expense for the
transition quarter was the issuance of MTNs issued by Energen in December 2000
and the issuance of the Notes by Alagasco in August 2001. The proceeds from the
Notes were used for repayment of borrowings under Energen's short-term credit
facilities incurred as a result of the growth at Energen Resources and for
general corporate purposes at Alagasco.

The Company's effective tax rate was lower than the statutory federal tax rate
primarily due to the recognition of nonconventional fuels tax credits and the
amortization of investment tax credits. Income tax expense decreased in quarter
comparisons primarily as a result of lower consolidated pre-tax income slightly
offset by higher nonconventional fuels tax credits of $1.2 million. The increase
in credit recognition reflected the annualized effective rate applied on an
interim basis in the three months ended December 31, 2000, as compared to the
transition period which was presented as a stand alone tax period in the current
quarter. The effective tax rate utilized in computing income tax expense
reflects financial recognition of $3.5 million of nonconventional fuels tax
credits as produced during the transitional quarter.

FINANCIAL POSITION AND LIQUIDITY
The Company's net cash from operating activities totaled $213.5 million, $156.5
million and $105 million in 2002, 2001 and 2000, respectively. In 2002,
operating cash flow benefited from significantly higher production volumes
related to Energen Resources' property acquisition and decreased storage
inventory balances at Alagasco. Operating cash flow in 2001 benefited from
significantly higher realized commodity prices at Energen Resources. Working
capital needs at Alagasco in 2001 were affected by increased gas costs and
colder-than-normal weather resulting in higher storage inventory balances. Other
working capital items, which primarily are the result of changes in throughput
and the timing of payments, combined to create the remaining increases for all
years.

During 2002, the Company made net investments of $268.2 million. Energen
Resources invested $184.2 million for property acquisitions, $122.5 million for
the development of proved properties and $0.1 million for exploration. In April
2002, Energen Resources completed its purchase of oil and gas properties located
in the Permian Basin in west Texas from First Permian, L.L.C. (First Permian)
for approximately $120 million in cash and 3,043,479 shares of the Company's
common stock. The total acquisition approximated $184 million and added 227 Bcfe
of reserves. Energen Resources drilled 232 gross development wells incurring
approximately $77 million. Energen Resources sold or traded certain properties
during the current year, resulting in cash proceeds of $17 million. Utility
expenditures in 2002 totaled $65.8 million and primarily represented system
distribution expansion and support facilities, including, information technology
application projects. Cash used in investing activities totaled $174.4 million
in 2001. During fiscal 2001, Energen Resources invested $34.3 million for
property acquisitions, $103.6 million for development of proved properties and
$1.2 million for exploration. Energen Resources drilled 140 gross development
wells spending approximately $70 million. Energen Resources sold or traded
certain properties during fiscal 2001, resulting in cash proceeds of $17.3
million. Utility expenditures for fiscal 2001 totaled $56.1 million, including
approximately $3 million for a municipal acquisition. Cash used in investing
activities totaled $131.7 million in 2000. Energen Resources invested $2.4
million for property acquisitions, $66.7 million for development and $1.2
million for exploration during fiscal 2000. Energen Resources drilled 141 gross
development wells incurring approximately $38 million. Utility expenditures in
2000 totaled $67.1 million.

During 2002, the Company added approximately 162 Bcfe of reserves. These reserve
additions are primarily the result of unit downspacing, which increases the
number of available drilling locations, for certain wells in the Black Warrior
and San Juan basins. Energen Resources' added approximately 50 Bcfe and 76 Bcfe
of reserves in fiscal year 2001 and 2000, respectively.


21

Net cash provided by financing activities totaled $53 million in 2002. In the
current year, the Company utilized $85.9 million in short-term credit
facilities to finance Energen Resources' acquisition strategy. Long-term debt
was reduced by $21.2 million, including the retirement of the Series 1993 Notes
for $7.8 million. Net cash provided by financing activities totaled $19.4
million in 2001. In August 2001 Alagasco issued 6.25% Notes for $40 million,
redeemable September 1, 2016, and 6.75% Notes for $35 million, redeemable
September 1, 2031, and in December 2000, Energen issued $150 million of
long-term debt redeemable December 15, 2010. The $223.8 million in net proceeds
were used to repay short-term borrowings incurred to finance Energen Resources'
growth activities and to repay additional borrowings by the utility as a result
of higher capital expenditures related to replacement of liquifaction equipment
and for general corporate purposes. The proceeds also were used to reduce
long-term debt by $36.3 million, including the retirement of the 8% Debentures
for $18.3 million. Net cash used in financing activities totaled $114.9 million
in 2000 resulting primarily from fluctuations in the amount and timing of
short-term debt at year-end. The Company borrowed $140.9 million at September
30, 1999 to invest in short-term federal obligations for tax planning purposes
that were sold in early October 2000 with the proceeds used to repay the
related debt. For each of the years, net cash used in financing activities also
reflected dividends paid to common stockholders and the issuance of common
stock through the dividend reinvestment and direct stock purchase plan and the
employee savings plans.

TRANSITION PERIOD: Cash flows from operations for the transition quarter were
$21.4 million compared to $20.7 million in the three months ended December 31,
2000. The decreased net income during the period was offset by changes in
working capital items, which are highly influenced by throughput, changes in
weather, and timing of payments.

The Company had a net investment of $35.7 million through the three months
ended December 31, 2001, primarily in additions of property, plant and
equipment. Energen Resources invested $25.1 million in capital expenditures
primarily related to the development of oil and gas properties. Utility capital
expenditures totaled $12.9 million in the quarter and primarily represented
system distribution expansion and support facilities. The Company had cash
proceeds of $2.3 million resulting from the sale of certain properties during
the transition period.

The Company's financing activities provided $15.5 million for the transition
quarter in net cash flows. Increased borrowings under Energen's short-term
credit facilities were used to finance Energen Resources' acquisition strategy
and general corporate needs at Alagasco.

CAPITAL EXPENDITURES

OIL AND GAS OPERATIONS: Energen Resources spent $546.6 million for capital
projects during the year ended December 31, 2002, the three months ended
December 31, 2001 and the years ended September 30, 2001 and 2000, $12.1
million of which was charged to income as exploration expense primarily due to
the writedown of a portion of an unproved leasehold. Property acquisition
expenditures totaled $221.2 million, development activities totaled $317.5
million, and exploratory expenditures totaled $2.7 million.

FUTURE CAPITAL RESOURCES AND LIQUIDITY

The Company plans to continue to implement its diversified growth strategy that
focuses on expanding Energen Resources' oil and gas operations through the
acquisition of producing properties with development potential while
maintaining the strength of the Company's utility foundation. For the five
calendar years ended December 31, 2002, Energen's EPS grew at an average
compound rate of 11.5 percent a year. Over the next five years, Energen is
targeting an average EPS growth rate over each rolling five-year period of 7
percent to 8 percent a year.

To finance Energen Resources' investment program, the Company expects to
utilize its short-term credit facilities to supplement internally generated
cash flow, with long-term debt and equity providing permanent financing.
Energen currently has available short-term credit facilities of $267 million to
help finance its growth plans and operating needs. As an acquisition company,
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. In February
2003, Moody's Investors Service confirmed Energen's debt rating as Baa1 and
Alagasco's debt rating as A1. Standard and Poor's last update in June 2002,
confirmed Energen's and Alagasco's rating as A- with a stable outlook. While
the Company expects to have ongoing access to it's short-term credit facilities
and the broader long-term markets, continued accessibility could be affected by
future economic and business conditions. Energen's management plans to utilize
increases in cash flows to help finance Energen Resources' acquisition
strategy.

In 2003, Energen Resources plans to invest approximately $158 million,
including $47 million in property acquisitions and related development and $111
million in other development and exploratory activities. Included in this $111
million is approximately $65 million for the development of previously
identified proved undeveloped reserves and exploratory exposure of
approximately $3 million. Capital investment at Energen Resources in 2004 is
expected to approximate $123 million for property acquisitions and related
development and $68 million for other development and exploration. Of this $68
million, development of previously identified proved undeveloped reserves is
estimated to be $35 million and exploratory exposure is estimated to be $3
million. Energen Resources' capital investment for oil and gas activities over
the five-year period ending December 31, 2007 is estimated to be approximately
$835 million, with $590 million for property acquisitions and related
development, $222 million for other development and $23 million for exploratory
and other activities. During the five year period, Energen Resources
anticipates spending approximately $120 million on development of previously
identified proved undeveloped reserves and incurring approximately $15 million
in exploratory exposure. During this period, the Company expects to issue
approximately $75 million in long-term debt and an estimated $25 million in
equity to replace short-term obligations and to provide permanent financing for
its acquisition strategy. The Company will also provide up to $14 million a
year from the issuance of common stock through the dividend reinvestment and
direct stock purchase plan, and through employee savings plans. Energen
Resources' continued ability to invest in property acquisitions will be
influenced significantly by industry trends, as the producing property
acquisition market historically has been cyclical. Notwithstanding the
estimated expenditures mentioned above, as an


23

acquisition oriented company Energen Resources continually evaluates
acquisition opportunities which arise in the marketplace and from time to time
may pursue acquisitions that meet Energen's acquisition strategy. These
acquisitions may alter the aforementioned financing requirements. Additionally,
Energen Resources may enter into negotiations to sell, trade or otherwise
dispose of properties which may reduce or eliminate the amount of additional
financing described above.

During 2003, Alagasco plans to invest approximately $57 million in utility
capital expenditures for normal distribution and support systems. Alagasco
maintains an investment in storage gas that is expected to average
approximately $42 million in 2003. Alagasco plans to invest approximately $55
million in utility capital expenditures during 2004. The utility anticipates
funding these capital requirements through internally generated capital and the
utilization of short-term credit facilities. Over the Company's five-year
planning period ending September 30, 2007, Alagasco anticipates capital
investments of approximately $265 million.

CONTRACTUAL CASH OBLIGATIONS AND OTHER COMMITMENTS

In the course of ordinary business activities, Energen enters into a variety of
contractual cash obligations and other commitments. The following table
summarizes the Company's significant contractual cash obligations, other than
hedging contracts as of December 31, 2002.

(1) Long-term cash obligations include $1.6 million of unamortized debt
discounts as of December 31, 2002.

(2) Certain of the Company's long-term contracts for the supply, storage
and delivery of natural gas include fixed charges that amount to approximately
$265.4 million through October 2010. The Company also is committed to purchase
minimum quantities of gas at market-related prices or to pay certain costs in
the event the minimum quantities are not taken. These purchase commitments are
approximately 55.4 billion cubic feet through October 2004.

Alagasco entered into an agreement with a financial institution whereby it can
sell on an ongoing basis, with recourse, certain installment receivables
related to its merchandising program up to a maximum of $20 million as further
described in Note 8.

OUTLOOK

OIL AND GAS OPERATIONS: Energen Resources plans to continue to implement its
acquisition and development program with capital spending in fiscal years 2003
and 2004 as outlined above. Production in 2003 is expected to be approximately
85 Bcfe, including 82.4 Bcfe of estimated production from proved reserves owned
at December 31, 2002. In 2004, production is estimated to reach approximately
87 Bcfe, including approximately 77 Bcfe produced from proved reserves
currently owned.

Nonconventional fuels tax credits were generated annually on qualified
production through December 31, 2002. To mitigate the effects of the tax credit
benefit, Energen Resources has replaced a portion of the tax credits with
revenue-generating property acquisitions and related development affecting
corporate earnings in 2003 and has increased the number of available drilling
locations through unit downspacing in the Black Warrior Basin.

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. Energen


24

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, national supply and
demand factors and general economic conditions. Crude oil prices also are
affected by quality differentials, worldwide political developments and 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 variations and the availability and price of
transportation to consuming areas.

Energen Resources periodically enters into cash flow derivative commodity
instruments to hedge its exposure to oil, natural gas and natural gas liquids
price fluctuations. In addition, Alagasco enters into cash flow derivative
commodity instruments to hedge its exposure to price fluctuations on its gas
supply. Such instruments include regulated natural gas and crude oil futures
contracts traded on the New York Mercantile Exchange (NYMEX) and
over-the-counter swaps, collars and basis hedges with major energy derivative
product specialists. The counterparties to the commodity instruments are
investment banks and energy-trading firms. In some contracts, the amount of
credit allowed before Energen Resources or Alagasco must post collateral for
out-of-the-money hedges varies depending on the credit rating of the Company's
debt. In cases where this arrangement exists, generally the Company's credit
ratings must be maintained at investment grade status to have available
counterparty credit. All hedge transactions are subject to the Company's risk
management policy, approved by the Board of Directors, which does not permit
speculative positions. Energen Resources may hedge up to 80 percent of its
estimated annual production under this policy. As acquisitions are made,
Energen Resources may use futures, swaps and/or fixed-price contracts to hedge
commodity prices for up to 36 months in order to protect targeted returns.

As of December 31, 2002, 78 percent of Energen Resources' estimated 2003 gas
production, excluding anticipated acquisition volumes, was hedged or under
contract. These hedges included 30.9 Bcf of its estimated gas production at an
average NYMEX price of $4.13 per Mcf, 4.4 Bcf of basin-specific hedges at an
average contract price of $3.86 and 4.8 Bcf of gas production hedged with a
basin-specific collar price of $3.72 to $4.70 per Mcf. The Company also had
hedges in place for 2,478 MBbl or 68 percent of its estimated 2003 oil
production, excluding anticipated acquisition volumes, at an average NYMEX
price of $26.26 per barrel and 38 MMGal or 53 percent of its estimated 2003
natural gas liquids production at an average price of $0.42 per gallon. In
addition, the Company had hedged the basis difference on 11.7 Bcf of its
estimated 2003 gas production and 2,174 MBbl of its oil production. Subsequent
to December 31, 2002, Energen Resources entered into additional hedges for
2003, resulting in a total of 2,628 MBbl of its estimated 2003 oil production
hedged at an average NYMEX price of $26.36. The Company also entered into
additional basis hedges resulting in a total of 15.7 Bcf of basis hedges on its
estimated 2003 gas production and 2,271 MBbl of basis hedges on its estimated
2003 oil production.

At December 31, 2002, Energen Resources had entered into swaps for 6.5 Bcf of
its estimated 2004 gas production at an average NYMEX price of $4.02 per Mcf
and 2.4 Bcf of its estimated 2004 gas production hedged with a NYMEX collar
price of $4.05 to $4.44 per Mcf. Subsequent to December 31, 2002, Energen
Resources entered into additional hedges for 2004, resulting in a total of 8.9
Bcf of its estimated 2004 gas production hedged at an average NYMEX price of
$4.13 per Mcf, 120 MBbl of its estimated 2004 oil production hedged at an
average NYMEX price of $26.15 and 13.9 Bcf of basin-specific hedges at an
average contract price of $3.83 per Mcf. In addition, the Company hedged 30
MMGal of its estimated 2004 natural gas liquids production at an average price
of $0.41 per gallon. For 2005, Energen Resources had entered into swaps for 1.2
Bcf of its gas production at an average NYMEX price of $3.75 per Mcf.

The Company has prepared a sensitivity analysis to evaluate the hypothetical
effect that changes in the market value of crude oil, natural gas and natural
gas liquids may have on the fair value of its derivative instruments. This
analysis measured the impact on the commodity derivative instruments and,
thereby, did not consider the underlying exposure related to the commodity. At
December 31, 2002, the Company estimated that a 10 percent increase in the
commodities prices would have resulted in a $27.2 million change in the fair
value of open derivative contracts while a 10 percent decrease in the
commodities prices would have resulted in a $26.6 million change in the fair
value of open derivative contracts; however, gains and losses on derivative
contracts are expected to be similarly offset by sales at the spot market
price. At December 31, 2001 and September 30, 2001, the Company estimated that
a 10 percent change in the commodities prices would have resulted in a $2.1
million and a $6.9 million change, respectively, in the fair value of open
derivative contracts. Due to the short duration of the


25

contracts, the time value of money was not considered. The hypothetical change
in fair value was calculated by multiplying the difference between the
hypothetical price and the contractual price by the contractual volumes and did
not include the variance in basis or the impact of related taxes on actual cash
prices.

NATURAL GAS DISTRIBUTION: The extension of RSE in June 2002 provides Alagasco
the opportunity to continue earning an allowed ROE between 13.15 percent and
13.65 percent through January 1, 2008. Under the terms of that extension, RSE
will continue, unless, after notice to the Company and a hearing, the
Commission votes to either modify or discontinue its operation. As discussed in
Note 2,the utility's CCM is based in part on the number of residential
customers and the rate of inflation. Continued low inflation, significantly
higher gas prices resulting in increased bad debt expense and/or the lack of
customer growth could impact the utility's ability to manage its O&M expense
per customer sufficiently for the inflation-based cost control requirements of
RSE and may result in an average return on equity lower than the allowed range
of return due to the operation of the CCM. Over this period, Alagasco has the
potential for net income growth as the investment in additional utility plant
affects the level of equity required in the business. The utility continues to
rely on rate flexibility to effectively prevent bypass of its distribution
system. Even though the utility enjoys a market saturation rate higher than the
national average, customer growth in the service territory is limited.

On December 4, 2000, the APSC authorized Alagasco to engage in energy risk
management activities to manage the utility's cost of gas supply. As required
by SFAS No. 133, Alagasco recognizes all derivatives at their fair values as
either assets or liabilities on the balance sheet. Any gains or losses are
passed through to customers using the mechanisms of the GSA in compliance with
it's APSC-approved tariff. In accordance with SFAS No. 71, "Accounting for the
Effects of Certain Types of Regulation," Alagasco had recorded a regulatory
liability of $16.8 million representing the fair value of derivatives as of
December 31, 2002.

FORWARD-LOOKING STATEMENT AND RISK: 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 Company's forward-looking statements do not
reflect the impact of possible or pending acquisitions, divestitures or
restructurings. The Company cannot guarantee the absence of errors in input
data, calculations and formulas used in its estimates, assumptions and
forecasts. The Company undertakes no 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, future business decisions, and other
uncertainties, all of which are difficult to predict.

There are numerous uncertainties inherent in estimating quantities of proved
oil and gas reserves and in projecting future rates of production and timing of
development expenditures. The total amount or timing of actual future
production may vary significantly from reserve and production estimates. In the
event Energen Resources Corporation is unable to fully invest its planned
acquisition, development and exploratory expenditures, future operating
revenues, production, and proved reserves could be negatively affected. The
drilling of development and exploratory wells can involve significant risks,
including those related to timing, success rates and cost overruns and these
risks can be affected by lease and rig availability, complex geology and other
factors.

Although Energen Resources makes use of futures, swaps and fixed-price
contracts to mitigate risk, fluctuations in future oil and gas prices could
materially affect the Company's financial position and results of operation;
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.

RECENT PRONOUNCEMENTS OF THE FINANCIAL ACCOUNTING STANDARDS BOARD (FASB)


26

In July 2001, the FASB issued SFAS No. 143, "Accounting for Asset Retirement
Obligations," which requires entities to record the fair value of a liability
for an asset retirement obligation in the period in which it is incurred. The
Company adopted this statement as of January 1, 2002 (See Note 10).

The FASB issued SFAS No. 146, "Accounting for Costs Associated with Exit or
Disposal Activities" in June 2002. This statement requires that a liability for
costs associated with exit or disposal activities be recognized at fair value
in the period the liability is incurred. This Statement does not apply to costs
associated with the retirement of long-lived assets covered by SFAS No. 143.
The Company has adopted this statement for disposal or exit activities
initiated after December 31, 2002.

The FASB issued SFAS No. 148, "Accounting for Stock-Based Compensation -
Transition and Disclosure" in December 2002. This statement is effective for
2003 and amends SFAS No. 123, "Accounting for Stock-Based Compensation" by
providing alternative methods of transition for a voluntary change to the fair
value based method of accounting for stock-based employee compensation. In
addition, SFAS No. 148 requires additional disclosures related to the effect of
stock-based compensation on reported results. The Company has adopted the
disclosure provisions of SFAS No. 148 and is currently reviewing its treatment
of stock-based compensation as well as the impact of this pronouncement.

The FASB issued Interpretation No. 45, "Guarantor's Accounting and Disclosures
Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of
Others," (FIN 45) in November 2002. FIN 45 clarifies the requirements of SFAS
No. 5, "Accounting for Contingencies," related to a guarantors accounting for,
and disclosures of, the issuance of certain types of guarantees. Management has
completed a review of potential contingencies and noted the following guarantee
disclosure: Alagasco has an agreement with a financial institution whereby it
can sell on an ongoing basis, with recourse, certain installment receivables
related to its merchandising program up to a maximum of $20 million. Alagasco's
exposure to credit loss in the event of non-performance by customers is
represented by the balance of installment receivables (see Note 8). The Company
is required to adopt the provisions for initial recognition and measurement for
all guarantees issued or modified after December 31, 2002 on a prospective
basis. The Company is currently reviewing the impact related to the initial
recognition and measurement guarantees of this Interpretation.

In January 2003, the FASB issued Interpretation No. 46, "Consolidation of
Variable Interest Entities" (FIN 46) which clarifies the application of
Accounting Research Bulletin No. 51, "Consolidated Financial Statements." This
Interpretation provides guidance on the identification and consolidation of
variable interest entities (VIEs), whereby control is achieved through means
other than through voting rights. Management has completed an analysis of FIN
46 and has determined that the Company does not have VIEs.

REPORT OF MANAGEMENT

The accompanying consolidated financial statements and related notes of Energen
Corporation and subsidiaries and the financial statements and related notes of
Alabama Gas Corporation (collectively, "the financial statements") were
prepared by management, which has the primary responsibility for the integrity
of the financial information therein. These financial statements were prepared
in conformity with accounting principles generally accepted in the United
States of America appropriate in the circumstances and include amounts which
are based necessarily on management's best estimates and judgments. Financial
information presented elsewhere in this report is consistent with the
information in the financial statements.

Management maintains a comprehensive system of internal accounting controls and
relies on the system to discharge its responsibility for the integrity of the
financial statements. This system provides reasonable assurance that corporate
assets are safeguarded and that transactions are recorded in such a manner as
to permit the preparation of materially reliable financial information.
Reasonable assurance recognizes that the cost of a system of internal
accounting controls should not exceed the related benefits. This system of
internal accounting controls is augmented by written policies and procedures,
internal auditing, and the careful selection and training of qualified
personnel. As of December 31, 2002, management was aware of no material
weaknesses in Energen or Alabama Gas Corporation's systems of internal
accounting controls.

The financial statements have been audited by the Company's independent
accountants, whose opinions are expressed elsewhere in this Form 10-K. Their
audits were conducted in accordance with generally accepted auditing standards;
and, in connection therewith, they obtained an understanding of the Company's
systems of internal accounting controls and conducted such tests and related
procedures as they deemed necessary to arrive at an opinion on the fairness of
presentation of the financial statements.

The functioning of the accounting system and related internal accounting
controls is under the general oversight of the Audit Committee of the Board of
Directors, which is comprised of four outside Directors. The Audit Committee
meets regularly with the independent accountants and representatives of
management to discuss matters regarding internal accounting controls, auditing
and financial reporting.

REPORT OF INDEPENDENT ACCOUNTANTS
TO THE SHAREHOLDERS OF ENERGEN CORPORATION:

In our opinion, the consolidated financial statements of Energen Corporation
listed in the accompanying index present fairly, in all material respects, the
financial position of Energen Corporation and subsidiaries at December 31, 2002
and 2001 and September 30, 2001, and the results of their operations and their
cash flows for the year ended December 31, 2002, the three months ended
December 31, 2001 and the years ended September 30, 2001 and 2000, in
conformity with accounting principles generally accepted in the United States
of America. In addition, in our opinion, the financial statement schedule
listed in the accompanying index presents fairly, in all material respects, the
information set forth therein when read in conjunction with the related
consolidated financial statements. These financial statements and financial
statement schedule are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements and
financial statement schedule based on our audits. We conducted our audits of
these statements in accordance with auditing standards generally accepted in
the United States of America, which require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements are free
of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We

NOTES TO FINANCIAL STATEMENTS

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
- -------------------------------------------------------------------------------

Energen Corporation (Energen or the Company) is a diversified energy holding
company engaged primarily in the acquisition, development, exploration and
production of oil and gas in the continental United States (oil and gas
operations) and in the purchase, distribution, and sale of natural gas
principally in central and north Alabama (natural gas distribution). The
following is a description of the Company's significant accounting policies and
practices.

On December 5, 2001, the Board of Directors of the Company approved a change in
the Company's fiscal year end from September 30 to December 31, effective
January 1, 2002. A transition report was filed on Form 10-Q for the period
October 1, 2001 to December 31, 2001. Alagasco has continued on a September 30
fiscal year for rate-setting purposes (rate year) and reports on a calendar
year for the Securities and Exchange Commission and all other financial
accounting reporting purposes.

A. PRINCIPLES OF CONSOLIDATION

The accompanying consolidated financial statements include the
accounts of the Company and its subsidiaries, principally Energen
Resources Corporation and Alabama Gas Corporation (Alagasco), after
elimination of all significant intercompany transactions in
consolidation. Certain reclassifications have been made to conform the
prior years' financial statements to the current-year presentation.

B. OIL AND GAS OPERATIONS

PROPERTY AND RELATED DEPLETION: Energen Resources follows the
successful efforts method of accounting for costs incurred in the
exploration and development of oil and gas reserves. Lease acquisition
costs are capitalized initially, and unproved properties are reviewed
periodically to determine if there has been impairment of the carrying
value, with any such impairment charged to exploration expense
currently. Exploratory drilling costs are capitalized pending
determination of proved reserves. If proved reserves are not
discovered, the exploratory drilling costs are expensed. Other
exploration costs, including geological and geophysical costs, are
expensed as incurred. All development costs are capitalized.
Depreciation, depletion and amortization expense is determined on a
field-by-field basis using the unit-of-production method based on
proved reserves. Anticipated abandonment and restoration costs are
capitalized and depreciated over the estimated useful life of the
related asset. The costs and related accumulated depletion of
properties sold or retired are removed from the accounts and the
resulting gains or losses are included in discontinued operations.

OPERATING REVENUE: Energen Resources utilizes the sales method of
accounting to recognize oil and gas production revenue. Under the
sales method, revenue is recognized for the Company's total takes of
oil and gas production that are sold to and payable by its customers.
Over-production liabilities are established only when it is estimated
that a property's over-produced volumes exceed the net share of
remaining reserves for such property. Energen Resources had no
material production imbalances at December 31, 2002.

DERIVATIVE COMMODITY INSTRUMENTS: Energen Resources periodically
enters into cash flow derivative commodity instruments to hedge its
exposure to price fluctuations on oil, natural gas and natural gas
liquids production. Such instruments include regulated natural gas and
crude oil futures contracts traded on the New York Mercantile Exchange
(NYMEX) and over-the-counter swaps, collars and basis hedges with
major energy derivative product specialists. The counterparties to the
commodity instruments are investment banks and energy-trading firms.
In some contracts, the amount of credit allowed before Energen
Resources must post collateral for out-of-the-money hedges varies
depending on the credit rating of the Company's debt. In cases where
this arrangement exists, generally the Company's credit ratings must
be maintained at investment grade status to have available
counterparty credit.


42

The Company adopted Statement of Financial Accounting Standard (SFAS)
No. 133 (subsequently amended by SFAS Nos. 137 and 138), "Accounting
for Derivative Instruments and Hedging Activities," on October 1,
2000. This statement 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 Company is required to measure
the effectiveness of the hedge, or the degree that the gain (loss) for
the hedging instrument offsets the loss (gain) on the hedged item, at
each reporting period. The effective portion of the gain or loss on
the derivative instrument is recognized in other comprehensive income
as a component of equity and subsequently reclassified into earnings
when the forecasted transaction affects earnings. The ineffective
portion of a derivative's change in fair value is required to be
recognized in earnings immediately. Derivatives that do not qualify
for hedge treatment under SFAS No. 133 must be recorded at fair value
with gains or losses recognized in earnings in the period of change.
As of December 31, 2002, all of the Company's derivatives qualified
for cash flow hedge accounting.

Additionally, the Company may also enter into derivatives that do not
qualify for cash flow hedge accounting but are considered by
management to represent valid economic hedges and are accounted for as
mark-to-market transactions. These economic hedges may include, but
are not limited to, basis hedges without a corresponding NYMEX hedge,
put options and hedges on non-operated or other properties for which
all of the necessary information to qualify for cash flow hedge
accounting is either not readily available or subject to change.

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

C. NATURAL GAS DISTRIBUTION

UTILITY PLANT AND DEPRECIATION: Property, plant and equipment is
stated at cost. The cost of utility plant includes an allowance for
funds used during construction. Maintenance is charged for the cost of
normal repairs and the renewal or replacement of an item of property
which is less than a retirement unit. When property which represents a
retirement unit is replaced or removed, the cost of such property is
credited to utility plant and, together with the cost of removal less
salvage, is charged to the accumulated reserve for depreciation.
Depreciation is provided on the straight-line method over the
estimated useful lives of utility property at rates established by the
Alabama Public Service Commission (APSC). Approved depreciation rates
averaged approximately 4.5 percent in the year ended December 31,
2002, for the three months ended December 31, 2001 and for the years
ended September 30, 2001 and 2000.

INVENTORIES: Inventories, which consist primarily of gas stored
underground, are stated at average cost.

OPERATING REVENUE AND GAS COSTS: In accordance with industry practice,
Alagasco records natural gas distribution revenues on a monthly- and
cycle-billing basis. The commodity cost of purchased gas applicable to
gas delivered to customers but not yet billed under the cycle-billing
method is deferred as a current asset.

REGULATORY ACCOUNTING: Alagasco is subject to the provisions of SFAS
No. 71, "Accounting for the Effects of Certain Types of Regulation."
In general, SFAS No. 71 requires utilities to capitalize or defer
certain costs or revenues, based upon approvals received from
regulatory authorities, to be recovered from or refunded to customers
in future periods.


43

DERIVATIVE COMMODITY INSTRUMENTS: As required by SFAS No. 133,
Alagasco recognizes all derivatives as either assets or liabilities on
the balance sheet. Any gains or losses are passed through to customers
using the mechanisms of the Gas Supply Adjustment (GSA) rider in
accordance with Alagasco's APSC approved tariff, as required by SFAS
No. 71.

TAXES ON REVENUES: Collections and payments of excise taxes are
reported on a gross basis. The amounts included in taxes other than
income taxes on the consolidated statements of income are as follows:



Three Months

------- ------ ------- -------
Total $21,591 $4,969 $28,766 $19,749
======= ====== ======= =======


D. INCOME TAXES

The Company uses the liability method of accounting for income taxes
in accordance with SFAS No. 109, "Accounting for Income Taxes." Under
this method, a deferred tax asset or liability is recognized for the
estimated future tax effects attributable to temporary differences as
well as tax credit carryforwards. Deferred tax assets and liabilities
are measured using enacted tax rates expected to apply to taxable
income in the years in which those temporary differences are expected
to be recovered or settled. The effect on deferred tax assets and
liabilities of a change in tax rates is recognized in the period of
the change. The Company and its subsidiaries file a consolidated
federal income tax return. Consolidated federal income taxes are
allocated to appropriate subsidiaries using the separate return
method.

E. CASH EQUIVALENTS

The Company includes highly liquid marketable securities and debt
instruments purchased with a maturity of three months or less in cash
equivalents.

F. EARNINGS PER SHARE

The Company's basic earnings per share amounts have been computed
based on the weighted-average number of common shares outstanding.
Diluted earnings per share amounts reflect the assumed issuance of
common shares for all potentially dilutive securities (see Note 9).

G. STOCK-BASED COMPENSATION

The Company currently reports stock-based employee compensation
through the disclosure-only provisions of SFAS No. 123, "Accounting
for Stock-Based Compensation." Accordingly, no compensation expense
has been recognized for its stock options. Had compensation cost for
these options been determined in accordance with SFAS No. 123, the
Company's net income and diluted earnings per share would have been as
follows:

========== ========= ========== ==========


The Company uses the Black-Scholes pricing model to calculate the fair
values of the options awarded, which are included in the pro forma
results above. For purposes of this valuation the following
assumptions were used to derive the fair values: a seven-year time of
exercise; an annualized volatility rate of 34.67 percent, 36.35
percent and 34.64 percent for the three months ended December 31,
2001, and the years ended September 30, 2001 and 2000, respectively; a
risk-free interest rate of 3.36 percent, 4.14 percent, and 5.76
percent for the three months ended December 31, 2001, and the years
ended September 30, 2001 and 2000, respectively; and a dividend yield
of 3.12 percent, 2.55 percent and 3.53 percent on options without
dividend equivalents for the three months ended December 31, 2001, and
the years ended September 30, 2001 and 2000, respectively. Options
with dividend equivalents assume no dividend yield for all periods
presented. The weighted-average grant-date fair value of options
granted for the three-months ended December 31, 2001, was $9.74 for
options granted with dividend equivalents and $6.52 for options
granted without dividend equivalents; $12.66 for options granted with
dividend equivalents and $9.27 for options granted without dividend
equivalents during the year-ended September 30, 2001; and $5.91 for
options granted without dividend equivalents in the year-ended
September 30, 2000. There were no options granted in the year ended
December 31, 2002.

H. ESTIMATES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported
amounts of assets and liabilities at the date of the financial
statements and the reported amount of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
Significant estimates with regard to these financial statements
include the estimate of proved oil and gas reserves and the related
present value of estimated future net revenues therefrom (see Note
19).

2. REGULATORY MATTERS
- -------------------------------------------------------------------------------

All of Alagasco's utility operations are conducted in the state of Alabama.
Alagasco is subject to regulation by the APSC which established the Rate
Stabilization and Equalization (RSE) rate-setting process in 1983. RSE was
extended with modifications in 2002, 1996, 1990, 1987 and 1985. On June 10,
2002, the APSC extended Alagasco's rate-setting methodology, RSE, without
change, for a six-year period through January 1, 2008. Alagasco's allowed range
of return on equity remains 13.15 percent to 13.65 percent throughout the term
of the order, subject to change in the event that the Commission, following a
generic rate of return hearing, adjusts the equity returns of all major energy
utilities operating under a similar methodology. Under RSE as extended, 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 13.15 percent to
13.65 percent. 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. RSE limits the utility's equity upon which a return is permitted to
60 percent of total capitalization and provides for certain cost control
measures designed to monitor Alagasco's operations and maintenance (O&M)
expense. Under the inflation-based cost control measurement established by the
APSC, if the percentage change in O&M expense per customer falls within a range
of 1.25 points above or below the percentage change in the Consumer Price Index
For All Urban Consumers (index range), no adjustment is required. If the change
in O&M expense per customer exceeds the index range, three-quarters of the
difference is returned to


45

customers. To the extent the change is less than the index range, the utility
benefits by one-half of the difference through future rate adjustments. The
increase in O&M expense per customer was above the index range for the rate
year ended September 30, 2002; as a result, the utility returned to customers
$0.3 million pre-tax through rate adjustments under the provisions of RSE. A
$12.4 million, $16.3 million and $9.1 million annual increase in revenues
became effective December 1, 2002, 2001 and 2000, respectively, under RSE as
extended.

Alagasco calculates a temperature adjustment to customers' monthly bills to
substantially remove the effect of departures from normal temperatures on
Alagasco's earnings. Adjustments to customers' bills are made in the same
billing cycle in which the weather variation occurs. The temperature adjustment
applies to residential, small commercial and small industrial customers.
Alagasco's rate schedules for natural gas distribution charges contain a GSA
rider, established in 1993, which permits the pass-through to customers of
changes in the cost of gas supply.

The APSC approved an Enhanced Stability Reserve (ESR), beginning fiscal year
1998 with an approved maximum funding level of $4 million, to which Alagasco
may charge the full amount of: (1) extraordinary O&M expenses resulting from
force majeure events such as storms, severe weather, and outages, when one or a
combination of two such events results in more than $200,000 of additional O&M
expense during a rate year; or (2) individual industrial and commercial
customer revenue losses that exceed $250,000 during the rate year, if such
losses cause Alagasco's return on average equity to fall below 13.15 percent.
During the year ended September 30, 2001, Alagasco charged $1.2 million against
the ESR related to extraordinary bad debt expense and revenue losses from
certain large industrial customers. Following a year in which a charge against
the ESR is made, the APSC provides for accretions to the ESR of no more than
$40,000 monthly until the maximum funding level is achieved. The ESR balances
of $3 million at December 31, 2002, and $2.7 million at December 31, 2001 and
September 30, 2001, respectively, are included in the consolidated financial
statements.

At December 31, 2002, Alagasco had a $18.7 million accrued obligation related
to its salaried and union pension plans. In accordance with SFAS No. 71,
Alagasco has established a regulatory asset of $14.7 million for the portion of
the accrued obligation to be recovered through rates in future periods.

The excess of total acquisition costs over book value of net assets of acquired
municipal gas distribution systems is included in utility plant and is being
amortized through Alagasco's rate-setting mechanism on a straight-line basis
over approximately 23 years. At December 31, 2002, December 31, 2001 and
September 30, 2001, the net acquisition adjustments were $13.8 million, $12.1
million and $12.4 million, respectively.

obligation to be recovered through rates in future periods in accordance with
SFAS No. 71. An intangible asset was recorded for the unrecognized prior
service cost of $4.3 million and the balance of $1.7 million was recorded as a
component of accumulated other comprehensive income, net of tax. Subsequent to
December 31, 2002, Energen contributed an additional $9 million to pension Plan
A assets.

The Company has supplemental retirement plans with certain key executives
providing payments on retirement, termination, death or disability. Expense
(income) under these agreements for the year ended December 31, 2002, the three

2002 and 2001 and at June 30, 2001, the accumulated post-retirement benefit
obligation related to these agreements was $10,093,000, $9,198,000 and
$5,465,000, respectively, and the projected benefit obligation was $15,209,000,
$14,082,000, and $10,750,000, respectively. An accrued post-retirement benefit
liability of $5,860,000, $5,589,000 and $2,408,000 was recorded at December 31,
2002 and 2001 and September 30, 2001, respectively.

The Company recorded a minimum pension liability for supplemental retirement
plans of $4.2 million at December 31, 2002. A corresponding amount was
recognized as an intangible asset for the unrecognized prior service cost of
$81,000 and the balance was recorded as a component of accumulated other
comprehensive income, net of tax, of $2.6 million.

In addition to providing pension benefits, the Company provides certain
post-retirement health care and life


52

insurance benefits. Substantially all of the Company's employees may become
eligible for certain benefits if they reach normal retirement age while working
for the Company. The projected unit credit actuarial method was used to
determine the normal cost and actuarial liability.

Health care cost trend rate GRADED RATE 7.50% 7.50% 7.50%


The weighted average health care cost trend rate at December 31, 2002 for both
salaried and union employees is a 10% graduated rate down to 6% per year for
employees under age 65 and a 12% graduated rate down to 6% per year for
employees at or above age 65. This rate used in determining the accumulated
post-retirement benefit obligation has an effect on the amounts reported. For
example, with respect to salaried employees, increasing the


54

weighted average health care cost trend rate by 1 percentage point would
increase the accumulated post-retirement benefit obligation by $2,708,000 and
the net periodic post-retirement benefit cost by $283,000. For union employees,
increasing the weighted average health care cost trend rate by 1 percentage
point would increase the accumulated post-retirement benefit obligation by
$2,152,000 and the net periodic post-retirement benefit cost by $213,000.

For both defined benefit plans and other post-retirement plans, certain
financial assumptions are used in determining the Company's projected benefit
obligation. These assumptions are examined periodically by the Company, and any
required changes are reflected in the subsequent determination of projected
benefit obligations.

The Company has a long-term disability plan covering most salaried employees.
The Company had expense for the year ended December 31, 2002 of $304,000. The
Company had no expense for this plan in the three-months ended December 31,
2001 and in the years ended September 30, 2001 and 2000.

6. COMMON STOCK PLANS
- -------------------------------------------------------------------------------

A majority of Company employees are eligible to participate in the Energen
Employee Savings Plan (ESP) by investing a portion of their compensation in the
ESP, with the Company matching a part of the employee investment by
contributing Company common stock (new issue or treasury shares) or funds for
the purchase of Company common stock. The ESP also contains employee stock
ownership plan provisions. At December 31, 2002, a total of 148,594 common
shares were reserved for issuance under the ESP. Expense associated with
Company contributions to the ESP was $3,963,000 for the year ended December 31,
2002, $803,000 for the three months ended December 31, 2001, and $3,597,000 and
$3,381,000 for the years ended September 30, 2001 and 2000, respectively.

In 1992 the Company adopted the Energen Corporation 1992 Long-Range Performance
Plan which provides for the award of up to 1,000,000 performance units, with
each unit equal to the market value of one share of common stock, to eligible
employees based on predetermined performance criteria at the end of a four-year
award period. Under the Plan, a portion of the performance units is payable
with Company common stock; accordingly, 700,000 shares have been reserved for
issuance. Under the Plan, 76,120 and 102,860 performance units were awarded in
the years ended September 30, 2001 and 2000, respectively. According to the
provisions of the Plan, no additional performance units can be awarded after
September 30, 2001. In October 2001, the Company added provisions for the award
of future performance units, comparable to the 1992 Long-Range Performance
Plan, under the 1997 Stock Incentive Plan. Under the 1997 Stock Incentive Plan,
111,760 performance units were awarded in the three months ended December 31,
2001. The Company recorded expense of $2,136,250 for the year ended December
31, 2002, $722,500 for the three months ended December 31, 2001, and $2,311,000
and $4,448,000 for the years ended September 30, 2001 and 2000, respectively,
under the Plans.

On November 27, 1997, the Company adopted the Energen Corporation 1997 Stock
Incentive Plan. The 1997 Stock Incentive Plan, along with the Energen
Corporation 1988 Stock Option Plan, provides for the grant of incentive stock
options, non-qualified stock options, or a combination thereof to officers and
key employees. Options granted under the Plans provide for purchase of Company
common stock at not less than the fair market value on the date the option is
granted. In addition, the 1997 Stock Incentive Plan provides for the grant of
restricted stock with 22,775 shares awarded in the three-months ended December
31, 2001 and 57,190 and 12,500 shares awarded in the years ended September 30,
2001 and 2000, respectively. The sale or transfer of the shares is limited
during the restricted period. The Company recorded expense of $742,875 for the
year ended December 31, 2002, $188,000 for the three-months ended December 31,
2001 and $583,000 and $97,000 for the years ended September 30, 2001 and 2000,
respectively, related to the restricted stock. Under the 1988 Stock Option
Plan, 540,000 shares of Company common stock reserved for issuance have been
granted. Under the 1997 Stock Incentive Plan, an additional 1,500,000 shares of
Company common stock were reserved for issuance during 2002 resulting in total
shares reserved for issuance of 2,800,000. All outstanding options are
incentive or non-qualified, vest within three years from date of grant, and
expire 10 years from the grant date. Transactions under the Plans are
summarized as follows:

In 1992 the Company adopted the Energen Corporation 1992 Directors Stock Plan
to pay part of the compensation of its non-employee directors in shares of
Company common stock. Under the Plan, no shares were awarded during the year
ended December 31, 2002, 6,000 shares were awarded during the three-months
ended December 31, 2001 and 4,800 and 5,054 shares were awarded during the
years ended September 30, 2001 and 2000, respectively, leaving 144,639 shares
reserved for issuance as of December 31, 2002.

In 1996 the Company amended its Dividend Reinvestment and Common Stock Purchase
Plan to include a direct stock purchase feature which allows purchases by
non-shareholders. In connection with the amendment, 1,500,000 shares were added
to the Plan. As of December 31, 2002, 843,218 common shares were reserved under
this Plan.

On April 26, 2000, the Company authorized the repurchase of up to 1,000,000
shares of the Company's common stock, in addition to the 500,000 shares
authorized on May 25, 1994. For the year ended December 31, 2002 the Company
repurchased 5,319 shares, for the three-months ended December 31, 2001 the
Company repurchased 55,074 shares, and for the years ended September 30, 2001
and 2000 the Company repurchased 91,600 and 290,000 shares, respectively. As of
December 31, 2002, a total of 787,718 shares remain authorized for future
repurchase.

On June 24, 1998, the Company adopted a Shareholder Rights Plan (the 1998 Plan)
designed to protect


56

shareholders from coercive or unfair takeover tactics. Under certain
circumstances, the 1998 Plan provides shareholders with the right to acquire
the Company's Series 1998 Junior Participating Preferred Stock (or, in certain
cases, securities of an acquiring person) at a significant discount. Terms and
conditions are set forth in a Rights Agreement between the Company and its
Rights Agent. Under the 1998 Plan, one right is associated with each
outstanding share of common stock. Rights outstanding under the 1998 Plan at
December 31, 2002, were convertible into 347,454 shares of Series 1998 Junior
Participating Preferred Stock (1/100 share of preferred stock for each full
right) subject to adjustment upon occurrence of certain take-over related
events. No rights were exercised or exercisable during the period. The price at
which the rights would be exercised is $70 per right, subject to adjustment
upon occurrence of certain take-over related events. In general, absent certain
take-over related events as described in the Plan, the rights may be redeemed
prior to the July 27, 2008, expiration for $0.01 per right.

In 1997 the Company adopted the 1997 Deferred Compensation Plan to allow
officers and non-employee directors to defer certain compensation. Amounts
deferred by a participant under the 1997 Deferred Compensation Plan are
credited to accounts maintained for a participant in either, a stock account or
an investment account. The stock account tracks the performance of the
Company's common stock, including reinvestment of dividends. The investment
account tracks the performance of certain mutual funds. The Company has funded,
and presently plans to continue funding, a trust in a manner that generally
tracks participants' accounts under the 1997 Deferred Compensation Plan. While
intended for payment of benefits under the 1997 Deferred Compensation Plan, the
trusts' assets remain subject to the claims of our creditors. Amounts earned
under the Deferred Compensation Plan and invested in Company common stock held
by the trust have been recorded as treasury stock, along with the related
deferred compensation obligation in the Consolidated Statements of
Shareholders' Equity.

7. COMMITMENTS AND CONTINGENCIES
- -------------------------------------------------------------------------------

CONTRACTS AND AGREEMENTS: Alagasco has various firm gas supply and firm gas
transportation contracts which expire at various dates through the year 2010.
These contracts typically contain minimum demand charge obligations on the part
of Alagasco.

ENVIRONMENTAL MATTERS: The Company is subject to various environmental
regulations. Management believes that the Company is in compliance with the
currently applicable standards of the environmental agencies to which it is
subject and that potential environmental liabilities are minimal. Alagasco is
in the chain of title of eight former manufactured gas plant sites, of which it
still owns four, and five manufactured gas distribution sites, of which it
still owns one. 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 results of operations or financial
condition of Alagasco. Also, to the extent Energen Resources has operating
agreements with various joint venture partners, environmental costs would be
shared proportionately.

To date, the Company's expenditures to comply with environmental or safety
regulations have not been material and are not expected to be significant in
the future. However, new regulations, enforcement policies, claims for damages
or other events could result in significant future costs.

LEGAL MATTERS: Energen and its affiliates are, from time to time, parties to
various pending or threatened legal proceedings. Certain of these lawsuits
include claims for punitive damages in addition to other specified relief.
Based upon information presently available, and in light of available legal and
other defenses, contingent liabilities arising from threatened and pending
litigation are not considered material in relation to the respective financial
positions of Energen and its affiliates. It should be noted, however, that
Energen and its affiliates conduct business in Alabama and other jurisdictions
in which the magnitude and frequency of punitive damage awards may bear little
or no relation to culpability or actual damages, thus making it increasingly
difficult to predict litigation results.

Various legal proceedings arising in the normal course of business are in
progress currently, and the Company has accrued a provision for estimated
costs.


57

LEASE OBLIGATIONS: In January 1999 Alagasco closed on a sale-leaseback of the
Company's headquarters building. The proceeds from the sale approximated the
investment in the facility. The building is being leased back from the
purchaser over a 25-year lease term and the related lease is accounted for as
an operating lease. Under the terms of the lease, Energen has a renewal option;
the lease does not contain a bargain purchase price or a residual value
guarantee. Energen's total lease payments related to leases included as
operating lease expense, inclusive of the sale-leaseback, were $8,273,000 for
the year ended December 31, 2002, $1,837,000 for the three-months ended
December 31, 2001, $7,324,000 and $6,267,000 for the years ended September 30,
2001 and 2000, respectively. Minimum future rental payments required after 2002
under leases with initial or remaining noncancelable lease terms in excess of
one year are as follows:

$2,209,000 for the years ended September 30, 2001 and 2000, respectively.

8. FINANCIAL INSTRUMENTS AND RISK MANAGEMENT
- -------------------------------------------------------------------------------

FINANCIAL INSTRUMENTS: The fair value of cash and cash equivalents, trade
receivables (net of allowance), and short-term debt approximates fair value due
to the short maturity of the instruments. The fair value of Energen's
fixed-rate long-term debt, including the current portion, with a carrying value
of $537,533,000, would be $570,243,000 at December 31, 2002. The fair value of
Alagasco's fixed-rate long-term debt, including the current portion, with a
carrying value of $184,533,000, would be $200,410,000 at December 31, 2002. The
fair values were based on the market value of debt with similar maturities and
current interest rates.

Alagasco entered into an agreement with a financial institution whereby it can
sell on an ongoing basis, with recourse, certain installment receivables
related to its merchandising program up to a maximum of $20 million. Alagasco
sold installment receivables of $5,010,000 in the year ended December 31, 2002,
$2,120,000 in the three-months ended December 31, 2001 and $5,444,000 and
$6,879,000 in the years ended September 30, 2001 and 2000, respectively. At
December 31, 2002 the balance of these installment receivables was $10,566,000
and represented 13,812 accounts. At December 31, 2001 and September 30, 2001,
the balance of these installment receivables was $12,838,000 and $13,249,000,
respectively. Receivables sold under this agreement are considered financial
instruments with off-balance sheet risk. Alagasco's exposure to credit loss in
the event of non-performance by customers is represented by the balance of
installment receivables.

PRICE RISK: The Company adopted SFAS No. 133 (subsequently amended by SFAS Nos.
137 and 138) on October 1, 2000. This statement 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 Company is required to measure the
effectiveness of the hedge, or the degree that the gain (loss) for the hedging
instrument offsets the loss (gain) on the hedged item, at each reporting
period. The effective portion of the gain or loss on the derivative instrument
is recognized in other comprehensive income as a component of equity and
subsequently reclassified into earnings when the forecasted transaction affects
earnings. The ineffective portion of a derivative's change in fair value is
required to be recognized in earnings immediately. Derivatives that do not
qualify for hedge treatment under SFAS No. 133 must be recorded at fair value
with gains or losses recognized in earnings in the period of change.


58

Energen Resources periodically enters into cash flow derivative commodity
instruments to hedge its exposure to price fluctuations on oil, natural gas and
natural gas liquids production. Such instruments include regulated natural gas
and crude oil futures contracts traded on the New York Mercantile Exchange and
over-the-counter swaps, collars and basis hedges with major energy derivative
product specialists. The counterparties to the commodity instruments are
investment banks and energy-trading firms. In some contracts, the amount of
credit allowed before Energen Resources must post collateral for
out-of-the-money hedges varies depending on the credit rating of the Company's
debt. In cases where this arrangement exists, generally the Company's credit
ratings must be maintained at investment grade status to have available
counterparty credit.

Energen Resources had certain agreements with Enron North America Corp. (Enron)
as the counterparty as of October 1, 2001. As prescribed by SFAS No. 133, the
value of the outstanding Enron contracts which qualified for cash flow hedge
accounting treatment was reflected on the balance sheet as an asset and the
effective portion of the derivative was reported as other comprehensive income
(OCI), a component of shareholders' equity. These outstanding contracts ceased
to qualify as cash flow hedges during October 2001 as a result of Enron's
credit issues. The Company recorded an expense to O&M for the write-down to
fair value of the asset related to the effected derivative contracts. The
deferred revenues related to the non-performing hedges were recorded in
accumulated other comprehensive income until such time as they were
reclassified to earnings as originally forecasted to occur. As a result,
Energen's net income in the three-month transition period ended December 31,
2001, reflected a one-time, non-cash expense of $5.5 million, net of tax. Net
income in the year ended December 31, 2002, reflected a total non-cash benefit
of $5.7 million, net of tax, related to the Enron hedge position.

The Company had current losses on the fair value of derivatives of $15.9
million included in accounts payable and $1.9 million of non-current losses
included in deferred credits and other liabilities on the consolidated balance
sheet at December 31, 2002. At December 31, 2001 and September 30, 2001, the
Company had current gains on the fair value of derivatives of $3.6 million and
$22.5 million, respectively, included in prepayments and other and $3 million
and $3.2 million, respectively, of non-current gains included in deferred
charges and other.

As of December 31, 2002, $9.4 million, net of tax, of deferred net losses on
derivative instruments recorded in accumulated other comprehensive income are
expected to be reclassified to earnings during the next twelve-month period.
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. The Company
recorded a $0.8 million after-tax loss in 2002 for the ineffective portion of
the change in fair value of derivatives accounted for as cash flow hedges.
Also, Energen Resources recorded an after-tax gain of $151,000 in 2002 on
contracts which did not meet the definition of cash flow hedges under SFAS No.
133. As of December 31, 2002, all of the Company's swaps and hedges met the
definition of a cash flow hedge. Subsequent to December 31, 2002, the Company
entered into a hedge contract for 150 MBbl of oil that did not meet the
definition of a cash flow hedge. The contract is considered by management to be
an economic hedge and is accounted for as a mark-to-market transaction. The

All hedge transactions are subject to the Company's risk management policy,
approved by the Board of Directors, which does not permit speculative
positions. The Company formally documents all relationships between hedging
instruments and hedged items, as well as its risk management objective and
strategy for undertaking the hedge. This process includes specific
identification of the hedging instrument and the hedge transaction, the nature
of the risk being hedged and how the hedging instrument's effectiveness in
hedging the exposure to the hedged transaction's variability in cash flows
attributable to the hedged risk will be assessed. Both at the inception of the
hedge and on an ongoing basis, the Company assesses whether the derivatives
that are used in hedging transactions are highly effective in offsetting
changes in cash flows of hedged items. The Company discontinues hedge
accounting if a derivative has ceased to be a highly effective hedge. The
maximum term over which Energen Resources has hedged exposures to the
variability of cash flows is through September 30, 2005.

On December 4, 2000, the APSC authorized Alagasco to engage in energy
risk-management activities to manage the utility's cost of gas supply. As of
December 31, 2002, Alagasco had recorded a $16,750,000 receivable in
prepayments and other representing the fair value of derivatives. As required
by SFAS No. 133, Alagasco recognizes all derivatives as either assets or
liabilities on the balance sheet. Any gains or losses are passed through to
customers using the mechanisms of the GSA in accordance with Alagasco's APSC
approved tariff.

CONCENTRATION OF CREDIT RISK: Revenues and related accounts receivable from oil
and gas operations primarily are generated from the sale of produced natural
gas and oil to natural gas and oil marketing companies. Such sales are
typically made on an unsecured credit basis with payment due during the month
following the month of delivery. This concentration of sales to the energy
marketing industry has the potential to affect the Company's overall exposure
to credit risk, either positively or negatively, in that the Company's oil and
gas purchasers may be affected similarly by changes in economic, industry or
other conditions. During 2001 and 2002, the credit rating agencies downgraded
the credit ratings of a number of energy marketers and their affiliates,
including certain oil and gas purchasers of the Company. The Company is
monitoring this situation and, in certain instances, may require credit
assurances such as a deposit, letter of credit or parent guarantee. The three
largest oil and gas purchasers buy approximately 23%, 12% and 11%,
respectively, of Energen Resources' estimated 2003 production. Energen
Resources' other purchasers each buy less than 10% of production.

Natural gas distribution operating revenues and related accounts receivable are
generated from state-regulated utility natural gas sales and transportation to
approximately 465,000 residential, commercial and industrial customers located
in central and north Alabama. A change in economic conditions may affect the
ability of customers to meet their obligations; however, the Company believes
that its provision for possible losses on uncollectible accounts receivable is
adequate for its credit loss exposure.

10. ASSET RETIREMENT OBLIGATIONS
- -------------------------------------------------------------------------------

The Company has adopted SFAS No. 143, "Accounting for Asset Retirement
Obligations," which requires the Company to record the fair value of a
liability for an asset retirement obligation (ARO) in the period in which it is
incurred. Upon adoption of SFAS No. 143, the Company was required to recognize
a liability for the present value of all legal obligations associated with the
retirement of tangible long-lived assets and capitalize an equal amount as a
cost of the asset as of January 1, 2002. Upon initial application of the
Statement, a cumulative effect of a change in accounting principle was also
required in order to recognize a liability for any existing AROs adjusted for
cumulative accretion, an increase to the carrying amount of the associated
long-lived asset and accumulated depreciation on the capitalized cost.
Subsequent to initial measurement, liabilities are required to be accreted to
their present value each period and capitalized costs are depreciated over the
estimated useful life of the related assets. Upon settlement of the liability,
the Company will settle the obligation for its recorded amount and will record
in resulting gain or loss.

Energen Resources recorded a liability representing expected future costs
associated with site reclamation, facilities dismantlement, and plug and
abandonment of wells as follows:



(in thousands)


Balance of ARO as of January 1, 2002 $ 20,493
Liabilities incurred during the year ended December 31, 2002 4,923
Accretion expense 1,819
--------
Balance of ARO as of December 31, 2002 $ 27,235
========


For the year ended December 31, 2002, Energen Resources recognized additional
costs of $20.1 million, depreciation expense of $1.7 million, a deferred tax
asset of $1.3 million and an after-tax charge of $2.2 million for the
cumulative effect on prior years.


61

The Company's gas distribution system operates under various property easement
agreements primarily related to public rights of way. In some instances, the
entity granting the easement retains the option to require certain actions in
the event the Company abandons the asset. Since the Company expects its gas
distribution assets will be operated in perpetuity and historical abandonment
costs resulting from such easement agreements have been de minimis, no asset
retirement obligation has been recorded.

------- ------ ------- -------


12. LONG-LIVED ASSETS AND DISCONTINUED OPERATIONS
- -------------------------------------------------------------------------------

On January 1, 2002, the Company adopted SFAS No. 144, "Accounting for the
Impairment or Disposal of Long-Lived Assets." This statement retains the
previous asset impairment requirements of SFAS No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of"
for loss recognition when the carrying value of an asset exceeds the sum of the
undiscounted estimated future cash flow of the asset. In addition, SFAS No. 144
requires that gains and losses in the sale of certain oil and gas properties
and write-downs of certain properties held-for-sale be reported as discontinued
operations, with income or loss from operations of the associated properties
reported as income or loss from discontinued operations. All assets
held-for-sale must be reported at the lower of the carrying amount or fair
value. Accordingly, during the second quarter of 2002, Energen Resources
recorded a pre-tax writedown of $2.8 million on certain non-strategic gas
properties located in the Gulf Coast region, adjusting the carrying amount of
the properties to their fair value based upon expected future discounted cash
flows. In November 2002, the Company sold these properties for approximately
the carrying amount. The gain on disposals for the year ended December 31,
2002, included a total of $3.7 million largely due to sales of property located
in the Permian Basin. As of December 31, 2002, the Company had no properties
classified as held-for-sale.


62

In 2001 and 2000, a pre-tax gain of $0.8 million and $1.1 million,
respectively, was recorded in operating revenues from continuing operations for
certain non-strategic property sales. In the third fiscal quarter of 2000, as a
result of a downward reserve revision in a small oil and gas field, Energen
Resources recorded a pre-tax write-down of $3.5 million in additional
depreciation, depletion and amortization expense, adjusting the carrying amount
of the properties to their fair value based on expected future discounted cash
flows.

The following are the results of operations from discontinued operations:

14. ACQUISITION OF OIL AND GAS PROPERTIES
- -------------------------------------------------------------------------------

On April 8, 2002, Energen Resources completed its purchase of oil and gas
properties located in the Permian Basin in west Texas from First Permian,
L.L.C. (First Permian), for approximately $120 million cash and 3,043,479
shares of the Company's common stock. The common stock was valued at $23.95 per
share, the average stock price at the time Energen signed the related Purchase
and Sale Agreement. The total acquisition approximated $184 million; this
estimate reflects an effective date of January 1, 2002, with appropriate
purchase price adjustments from that date forward until completion of the
transaction, resulting from interim cash flows and related tax items.

Summarized below are the consolidated results of operations for the year ended
December 31, 2002, the three months ended December 31, 2001 and the year ended
September 30, 2001, on an unaudited pro forma basis as if the acquisition had
occurred at the beginning of each period presented. The pro form information is
based on our consolidated results of operations for the year ended December 31,
2002, the three months ended December 31, 2001 and the year ended September 30,
2001, and on the data provided by the acquired companies, after giving effect
to the issuance of 3,043,479 million shares of common stock. The pro forma
financial information does not purport to be indicative of results of
operations that would have occurred had the transaction occurred on the basis
assumed above nor are they indicative of results of the future operations of
the combined enterprises.

18. RECENT PRONOUNCEMENTS OF THE FINANCIAL ACCOUNTING STANDARDS BOARD (FASB)

In July 2001, the FASB issued SFAS No. 143, "Accounting for Asset Retirement
Obligations," which requires entities to record the fair value of a liability
for an asset retirement obligation in the period in which it is incurred. The
Company adopted this statement as of January 1, 2002 (See Note 10).

The FASB issued SFAS No. 146, "Accounting for Costs Associated with Exit or
Disposal Activities" in June 2002. This statement requires that a liability for
costs associated with exit or disposal activities be recognized at fair value in
the period the liability is incurred. This Statement does not apply to costs
associated with the retirement of long-lived assets covered by SFAS No. 143. The
Company has adopted this statement for disposal or exit activities initiated
after December 31, 2002.

The FASB issued SFAS No. 148, "Accounting for Stock-Based Compensation -
Transition and Disclosure" in December 2002. This statement is effective for
2003 and amends SFAS No. 123, "Accounting for Stock-Based Compensation" by
providing alternative methods of transition for a voluntary change to the fair
value based method of accounting for stock-based employee compensation. In
addition, SFAS No. 148 requires additional disclosures related to the effect of
stock-based compensation on reported results. The Company has adopted the
disclosure provisions of SFAS No. 148 and is currently reviewing its treatment
of stock-based compensation as well as the impact of this pronouncement.

The FASB issued Interpretation No. 45, "Guarantor's Accounting and Disclosures
Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of
Others," (FIN 45) in November 2002. FIN 45 clarifies the requirements of SFAS
No. 5, "Accounting for Contingencies," related to a guarantors accounting for,
and disclosures of, the issuance of certain types of guarantees. Management has
completed a review of potential contingencies and noted the following guarantee
disclosure: Alagasco has an agreement with a financial institution whereby it
can sell on an ongoing basis, with recourse, certain installment receivables
related to its merchandising program up to a maximum of $20 million. Alagasco's
exposure to credit loss in the event of non-performance by customers is
represented by the balance of installment receivables (see Note 8). The Company
is required to adopt the provisions for initial recognition and measurement for
all guarantees issued or modified after December 31, 2002 on a prospective
basis. The Company is currently reviewing the impact related to the initial
recognition and measurement guarantees of this Interpretation.

In January 2003, the FASB issued Interpretation No. 46, "Consolidation of
Variable Interest Entities" (FIN 46) which clarifies the application of
Accounting Research Bulletin No. 51, "Consolidated Financial Statements." This
Interpretation provides guidance on the identification and consolidation of
variable interest entities (VIEs), whereby control is achieved through means
other than through voting rights. Management has completed an analysis of FIN 46
and has determined that the Company does not have VIEs.

19. OIL AND GAS OPERATIONS (UNAUDITED)

The following schedules detail historical financial data of the Company's oil
and gas operations. Certain terms appearing in the schedules are prescribed by
the Securities and Exchange Commission (SEC) and are briefly described as
follows:

EXPLORATION EXPENSES are costs primarily associated with drilling unsuccessful
exploratory wells in undeveloped properties, exploratory geological and
geophysical activities, and costs of impaired and expired leaseholds.

DEVELOPMENT COSTS include costs necessary to gain access to, prepare and equip
development wells in areas of proved reserves.

PRODUCTION (LIFTING) COSTS include costs incurred to operate and maintain wells.

GROSS REVENUES are reported after deduction of royalty interest payments.

GROSS WELL OR ACRE is a well or acre in which a working interest is owned.

NET WELL OR ACRE is deemed to exist when the sum of fractional ownership working
interests in gross wells or acres equals one.

DRY WELL is an exploratory or a development well found to be incapable of
producing either oil or gas in sufficient quantities to justify completion as an
oil or gas well.

PRODUCTIVE WELL is an exploratory or a development well that is not a dry well.

As of December 31, 2002, the Company was participating in the drilling of 6
gross development wells, with the Company's interest equivalent to 3.31 wells.

PRODUCTIVE WELLS AND ACREAGE: The following table sets forth the total gross and
net productive gas and oil wells as of December 31, 2002, and developed and
undeveloped acreage as of the latest practicable date prior to year-end:



Gross Net

------- -------
Developed Acreage 772,519 428,080
Undeveloped Acreage 121,871 53,428
------- -------


There were 42 wells with multiple completions in 2002. All wells and acreage are
located onshore in the United States, with the majority of the net undeveloped
acreage located in the Permian Basin.

OIL AND GAS OPERATIONS: The calculation of proved reserves is made pursuant to
rules prescribed by the SEC. Such rules, in part, require that only proved
categories of reserves be disclosed and that reserves and associated values be
calculated using year-end prices and current costs. Changes to prices and costs
could have a significant effect on the disclosed amount of reserves and their
associated values. In addition, the estimation of reserves inherently requires
the use of geologic and engineering estimates which are subject to revision as
reservoirs are produced and developed and as additional information is
available. Accordingly, the amount of actual future production may vary
significantly from the amount of reserves disclosed. The proved reserves are
located onshore in the United States of America.

STANDARDIZED MEASURE OF DISCOUNTED FUTURE NET CASH FLOWS RELATING TO PROVED OIL
AND GAS RESERVES: The standardized measure of discounted future net cash flows
is not intended, nor should it be interpreted, to present the fair market value
of the Company's crude oil and natural gas reserves. An estimate of fair market
value would take into consideration factors such as, but not limited to, the
recovery of reserves not presently classified as proved reserves, anticipated
future changes in prices and costs, and a discount factor more representative of
the time value of money and the risks inherent in reserve estimates. At December
31, 2002, December 31, 2001, and September 30, 2001 and 2000, the Company had a
deferred hedging loss of $17.2 million, a deferred hedging gain of $15.2 million
and $25.7 million and a deferred hedging loss of $89.4 million, respectively,
all of which are excluded from the calculation of standardized measure of future
net cash flows.
