PART I

ITEM 1.     BUSINESS

GENERAL

Energen is a diversified energy holding company engaged primarily in natural
gas distribution and the exploration and production of natural gas and oil.

Energen was incorporated in Alabama in 1978 in connection with the
reorganization of its largest 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 late 1800's.  Alagasco
became a public company in 1953.

FINANCIAL INFORMATION ABOUT INDUSTRY SEGMENTS

The information required by this item is incorporated by reference from Note 12
Industry Segment Information to the Consolidated Financial Statements of the
1996 Annual Report to Stockholders, and is attached herein as Part IV, Item 14,
Exhibit 13.

NARRATIVE DESCRIPTION OF BUSINESS

- -  NATURAL GAS DISTRIBUTION

   GENERAL:  Alagasco, Energen's principal subsidiary, is the largest natural
   gas distribution utility in the state of Alabama.  Alagasco purchases
   natural gas through interstate and intrastate suppliers and distributes the
   purchased gas through its distribution facilities for sale to residential,
   commercial, industrial 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, acting
   on their own or using Alagasco as their agent, purchase gas directly from
   producers or other suppliers and arrange for delivery of the gas into the
   Alagasco distribution system. Alagasco then charges a fee to transport this
   customer-owned gas through its distribution system to the customer's
   facility.

   Alagasco's service territory is located primarily in central and north
   Alabama and includes over 175 communities in 30 counties.  Birmingham, the
   largest city in Alabama, and Montgomery, the state capital, are served by
   Alagasco.  The counties in which Alagasco provides service have an aggregate
   area of more than 22,000 square miles and include the service territories of
   various municipal gas distribution systems.

   The aggregate population of the counties served by Alagasco is estimated to
   be 2.4 million.  During 1996 Alagasco served an average of 418,486
   residential customers, 34,028 small commercial and industrial customers, and
   54 large commercial and industrial customers.  The Alagasco distribution
   system includes approximately 8,800 miles of main, more than 9,600 miles of
   service lines, odorization and regulation facilities, and customer meters.
   Alagasco also operates two liquefied natural gas facilities which it uses to
   meet peak demands.

   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 for the fourth time on October 7, 1996, for a five-year period
   through January 1, 2002. Under the terms of that extension, RSE will
   continue after January  1, 2002, unless, after notice to the Company and a
   hearing, the Commission votes to either modify or discontinue its operation.





                                       3
<PAGE>   4

   Under RSE, the APSC conducts quarterly reviews to determine, based on
   Alagasco's projections and fiscal year-to-date performance, whether
   Alagasco's return on equity for the fiscal 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 fiscal 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. If the change
   in O&M expense per customer falls within 1.25 percentage points above or
   below the Consumer Price Index For All Urban Customers (index range), no
   adjustment is required. If, however, 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. Under RSE as extended, an $8.2 million annual increase in
   revenue became effective December 1, 1995, and a $1.3 million decrease in
   revenue became effective October 1, 1996.

   Alagasco calculates a temperature adjustment to customers' monthly bills to
   remove the effect of departures from normal temperature on Alagasco's
   earnings. The calculation is performed monthly, and the adjustments to
   customers' bills are made in the same billing cycle the weather variation
   occurs.

   Alagasco's rate schedules for natural gas distribution charges contain a Gas
   Supply Adjustment (GSA) rider, which permits the pass-through to customers
   of changes in the cost of gas supply, including Gas Supply Realignment (GSR)
   surcharges imposed by Alagasco's suppliers resulting from changes in gas
   supply purchases related to the implementation of Federal Energy Regulatory
   Commission (FERC) Order 636. On October 7, 1996, the APSC issued an order
   providing for the refund to customers of approximately $17.1 million,
   including interest, of supplier refunds. The Order provides that refunds
   shall be returned to customers prior to January 31, 1997. These refunds were
   collected from a variety of sources and most relate to the settlement of
   rate case and FERC Order 636 proceedings of Southern Natural Gas Company
   (Southern) as described herein.

   On September 9, 1996, the APSC approved Alagasco's application to issue $25
   million of debt, a portion of which will be used to fund the supplier
   refunds discussed above. On June 12, 1995, Alagasco received approval from
   the APSC to issue $50 million of debt, a portion of which was used to redeem
   all of Alagasco's 9 percent debentures and 11 percent First Mortgage Bonds.
   In connection with the early call of the redeemed debt, Alagasco paid an
   early call premium of approximately $1.3 million. Because the APSC
   authorized Alagasco to collect the early call premium through customer
   rates, a regulatory asset of $1.3 million was recorded at September 30,
   1995, and the amounts were collected during fiscal 1996.

   In accordance with APSC-directed regulatory accounting procedures, Alagasco
   in 1989 began returning to customers excess utility deferred taxes which
   resulted from a reduction in the federal statutory tax rate from 46 percent
   to 34 percent using the average rate assumption method. This method provides
   for the return to ratepayers of excess deferred taxes over the lives of the
   related assets. In 1993 those excess taxes were reduced as a result of a
   federal tax rate increase from 34 percent to 35 percent. Remaining excess
   utility deferred taxes of $2.7 million are being returned to ratepayers over
   approximately 14 years. At September 30, 1996 and 1995, regulatory
   liabilities of $5 million and $6 million, respectively, were included in the
   financial statements related to income taxes.

   FERC REGULATION:  On March 15, 1995, Southern filed a comprehensive
   settlement with the FERC in the form of a Stipulation and Agreement (the
   Settlement) to resolve all issues in Southern's six pending rate cases, as
   well as to resolve all GSR and transition cost issues resulting from the
   implementation of FERC Order 636. Alagasco was a supporting party to the
   Settlement. On April 11, 1996, the FERC issued its Order on Rehearing
   approving the Settlement with minor modifications. The Settlement, as
   approved by FERC, provides for the following: (1) the resolution of all cost
   of service and rate design issues in Southern's six pending rate cases and
   the establishment of reduced rates for the purpose of calculating rate case
   refunds; (2) the implementation of reduced settlement rates for supporting
   parties commencing March 1, 1995; (3) the resolution of all GSR and other
   transition cost issues resulting from FERC Order 636; (4) lower GSR cost
   recovery through the reduction and earlier payout of GSR costs; (5) a
   three-year moratorium on general rate increases; and (6) the resolution and
   disposition of all rate case





                                       4
<PAGE>   5

   and GSR refunds for supporting parties. With respect to this last point, the
   Settlement provides that all rate case refunds will be used to offset a
   portion of Southern's remaining GSR liability. In addition, as a result of
   the recalculated GSR surcharges for the period January 1, 1994, to February
   28, 1995, Southern refunded over-collected GSR costs. As a result of this
   FERC order, Alagasco received other refunds based on contracts with other
   suppliers whose prices were tied to Southern's rates. In total, $17.1
   million will be refunded to customers prior to January 31, 1997, and
   includes amounts received from Southern, other suppliers and accrued
   interest.

   The Settlement, as approved by FERC, resolves all issues relating to GSR and
   other transition costs with respect to supporting parties. Alagasco
   estimates that it has a remaining GSR liability of approximately $0.8
   million to be paid through December 1997 and approximately $1.4 million in
   other transition costs to be paid through June 1998.  Because these costs
   will be recovered in full from its customers, Alagasco recorded regulatory
   assets of $2.2 million and $5 million at September 30, 1996 and 1995,
   respectively.

   GAS SUPPLY:  The Alagasco distribution system is connected to and has firm
   transportation contracts with two major interstate pipeline
   systems--Southern and Transcontinental Gas Pipe Line Corporation. Effective
   November 1, 1993, Alagasco's pre-Order 636 contract demand and firm
   transportation with Southern converted to 250,924 Mcf (thousand cubic feet)
   per day of No-Notice Firm Transportation service for a period of 15 years,
   91,946 Mcf per day of Firm Transportation service for 15 years, and 50,000
   Mcf per day of Firm Transportation for five years.  Southern also unbundled
   its existing storage capacity.  Alagasco's pro rata share of this storage is
   12,426,687 Mcf.  Alagasco has a maximum withdrawal rate from storage of
   250,924 Mcf per day and a maximum injection rate into storage of 95,590 Mcf
   per day. The Transco firm transportation contract, which expires in 2001,
   provides for maximum daily firm transportation of up to 100,000 Mcf.  Thus
   the Company has a peak day firm interstate pipeline transportation capacity
   of 492,870 Mcf per day.

   Alagasco has replaced the sales service formerly provided by Southern with
   purchases from various gas producers and marketers including affiliates of
   Southern and Transco and from certain intrastate producers including Basin
   Pipeline Corp., an Energen subsidiary. Alagasco has contracts in place to
   purchase up to a total of 286,776 Mcf per day of firm supply, of which
   241,946 is supported by firm transportation on the Transco and Southern
   systems, 14,830 Mcf provides excess supply on the Southern system, and
   30,000 Mcf is purchased at the city gate from intrastate suppliers. This
   volume, along with Alagasco's maximum withdrawal from storage of 250,924 Mcf
   per day and 200,000 Mcf per day of liquefied natural gas peak shaving
   capacity, gives Alagasco a peak day firm supply of 722,870 Mcf per day.
   Alagasco also utilizes the Southern and Transco pipeline systems to access
   spot market gas in order to supplement its firm system supply and serve its
   industrial transportation customers.

   COMPETITION AND PRICING:  The price of natural gas is a significant
   marketing factor in the territory served by Alagasco; propane, coal and fuel
   oil are readily available, and many major industrial customers have the
   capability to switch to alternate fuels.  In the residential and small
   industrial and commercial markets, electricity is the principal competitor.

   Natural gas service available to Alagasco customers generally falls into two
   categories -- interruptible and firm.  Interruptible service is
   contractually subject to interruption by Alagasco for various reasons, the
   most common of which is curtailment of industrial customers during periods
   of peak residential heating demand on the Alagasco system.  Firm service is
   generally not subject to interruption and, therefore, is more expensive than
   interruptible service.  Firm service is generally provided to residential
   and small commercial and industrial customers.  Interruptible service is
   generally provided to large commercial and industrial customers which
   typically have the capacity to reduce consumption by adjusting their
   production schedules or by switching to alternate fuels during periods of
   interruption.  Deliveries of sales and transportation gas totaled 111,422
   MMcf (million cubic feet) in 1996.

   In 1994, capitalizing on federally mandated changes in the natural gas
   industry, Alagasco implemented the "P" Rate.  This tariff allows the utility
   to, in effect, release available pipeline capacity thereby reducing pipeline
   transportation costs for its 275 transportation customers. The lower costs
   help prevent bypass.  Also, because





                                       5
<PAGE>   6

   revenue received from capacity release reduces core market gas costs,
   Alagasco's competitive position in the residential and small commercial
   markets is enhanced as well.

   Alagasco has a Competitive Fuel Clause (CFC) as part of its rate tariff
   which allows Alagasco to adjust large commercial and industrial prices on a
   case-by-case basis to compete with either alternate fuels or alternate
   sources of gas.  The GSA rider to Alagasco's tariff increases the rates paid
   by other customers to recover the reduction in rates allowed under the CFC
   because the retention of any customer, particularly large commercial and
   industrial, benefits all customers by recovering a portion of the system's
   fixed cost.

   Alagasco also has a Transportation Tariff (the Tariff) which allows the
   Company to transport gas for customers rather than buying and reselling gas
   to them.  The Tariff is based on Alagasco's gas sales profit margin so that
   Alagasco's net income is not affected whether it transports or sells gas.
   The Tariff also may be adjusted under the CFC.  Of Alagasco's total large
   commercial and industrial customer deliveries during 1996, 99.95 percent
   (46,207 MMcf) was from transportation of customer-owned gas.

   GROWTH:  Alagasco has supplemented traditional service area growth with
   acquisitions of municipally-owned gas distribution systems.  Since 1985
   Alagasco has acquired 22 such systems, three of which were acquired in
   fiscal 1996 initially adding over 1,800 customers. More than 43,000
   customers have been added through initial system purchases and subsequent
   customer additions, as Alagasco has increased the relatively low saturation
   rates in the acquired areas through a variety of marketing efforts including
   offering natural gas service to propane customers already situated on the
   municipal system lines, extending the acquired municipal system into nearby
   neighborhoods that desire natural gas service, and marketing natural gas
   appliances to existing and new customers. Approximately 80 municipal
   systems, representing about 250,000 customers remain in Alabama, and many
   are located in or near Alagasco's existing service territory. The Company is
   optimistic that additional acquisition opportunities will arise in the
   future.

   WEATHER:  Alagasco's gas distribution business is highly seasonal since a
   material portion of Alagasco's total sales and delivery volumes is to
   customers whose use varies depending upon temperature, principally
   residential, small commercial and small industrial customers.  Alagasco's
   rate tariff includes a temperature adjustment rider which is designed to
   mitigate 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, of which it still owns four, and five
   manufactured gas distribution sites, of which it still owns one.  A
   preliminary 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.

- -  OIL AND GAS EXPLORATION AND PRODUCTION ACTIVITIES

   Energen's oil and gas exploration and production activities are conducted by
   its subsidiary, Taurus Exploration, Inc. (Taurus) and involve the
   acquisition, development, exploration and production of natural gas and oil
   from conventional and nonconventional reservoirs in the continental United
   States. Taurus's remaining recoverable reserves at the end of fiscal 1996
   totaled 250,867 million cubic feet equivalents (MMcfe) and are located
   primarily in Alabama, Louisiana, Texas and the Gulf of Mexico.

   As Energen's dominant growth vehicle, Taurus is continuing its strategic
   focus on acquiring conventional oil and gas producing properties with
   development potential and supplementing returns with relatively low-risk
   Gulf of Mexico exploration and related development.  Beginning with the 1996
   fiscal year, Energen embarked on an aggressive, five- year diversified
   growth strategy which calls for the Company to invest through Taurus $400
   million





                                       6
<PAGE>   7

   in producing property acquisitions and related development and $100 million
   in exploration and related development.

   In implementing Energen's growth strategy, Taurus works with a variety of
   experienced industry partners in its acquisition and exploration activities.
   Taurus also is working to increase its internal generation of acquisition
   opportunities. To help minimize risk, Taurus takes small working interest
   positions in numerous exploratory prospects rather than a large position in
   a few. Taurus also utilizes the natural gas and oil futures markets as well
   as fixed-price contracts as defensive mechanisms to mitigate the impact of
   commodity price volatility on targeted returns of reserve acquisitions and
   to manage overall price volatility on other production.

   The first year of implementation of Energen's diversified growth strategy
   resulted in Taurus investing $108 million for the acquisition of eight
   producing properties with development potential and participating in 12
   successful exploratory and development wells in the Gulf of Mexico. Net
   reserve additions totaled 171,801 MMcfe, production increased 60 percent to
   16,118 MMcfe, and the average sales price per MMcfe was $1.97.

   Taurus also serves as the operator of extensive Black Warrior Basin coalbed
   methane properties for its own interests and those of its partners, and also
   provides third-party operations. Since making the transition away from the
   development of new coalbed methane projects in the early 1990s, Taurus has
   continued to operate coalbed methane wells as a profitable business activity
   but looks to the acquisition, exploration and development of oil and gas
   reserves for long-term growth.

   PROPERTY ACQUISITIONS AND DEVELOPMENT: Taurus's largest property acquisition
   in fiscal 1996 was the $61 million purchase of 105 Bcf of coalbed methane
   reserves in Alabama from Burlington Resources Inc. Part of Burlington's
   accelerated divesture program, these Black Warrior Basin wells cover 19,000
   gross acres adjacent to existing coalbed methane interests of Taurus's in
   west central Alabama. Substantially all of these long-lived coalbed methane
   reserves are proved producing and complemented well Taurus's other reserve
   acquisitions which featured a greater amount of behind-pipe and proved
   undeveloped reserves. Production from 43 of the more than 100 wells
   qualifies for the nonconventional fuels tax credit, which presently is
   valued at $1 per Mcf of production and increases annually with inflation.

   Through its partnership with Sonat Exploration Company, a subsidiary of
   Birmingham-based Sonat Inc., Taurus invested $28 million in four
   conventional property acquisitions during fiscal 1996. Three of the
   properties are located in Louisiana and the other is located in the Gulf of
   Mexico, offshore Louisiana and Texas. Taurus's working interest  in these
   projects ranges from one-third to 40 percent. Taurus estimates its
   development costs related to these acquisitions will total approximately $20
   million over the next three to four years. Taurus joined Sonat Exploration's
   ongoing reserve acquisition efforts in the summer of 1995 through a
   three-and-a-half year agreement and plans to invest $25 million to $50
   million annually with Sonat in calendar years 1996, 1997 and 1998. Related
   development drilling may require additional investment on the part of Taurus
   over the ensuing five years of approximately 50 cents for each acquisition
   dollar.

   In September 1996, Taurus purchased a 75 percent working interest in the
   Odem Field in south Texas from Bargo Energy Company and Moran Resources
   Company and acquired estimated proved reserves of 21 Bcfe for $15 million.
   Taurus's share of future development costs could approximate $4 million.

   Early in fiscal 1996, Taurus made a small acquisition through its joint
   venture with PMC Reserve Acquisition Company and subsequently purchased the
   interest of another participant in PMC's acquisition program. In September
   1996, PMC sold its oil and gas properties; Taurus elected to sell its
   related interests of 11 Bcfe and realized a $3.2 million gain on its
   investment. As part of our ongoing business activities, Taurus may be
   involved, from time to time, in the sale of developed and undeveloped
   properties as a source of revenue as a result of, but not limited to,
   disposing of marginal assets and accepting offers where the buyer gives
   greater value to a property than Taurus's technical staff.





                                       7
<PAGE>   8


   EXPLORATION AND DEVELOPMENT: Taurus invested $18 million in offshore
   exploration and related development during 1996.  Through existing
   partnership arrangements with United Meridian Corporation (UMC) and King
   Ranch Oil & Gas, Taurus participated in 12 successful exploratory and
   development wells, adding 5 Bcf of natural gas to its proved reserves.

   Taurus utilizes several avenues to ensure a continuing flow of high quality
   exploratory prospects, including its participation in UMC's offshore
   exploratory program, a multi-year 3-D seismic joint venture with King Ranch
   and Holley Petroleum, Inc., covering 200 offshore Texas blocks, and other
   offshore lease sales with various industry partners.

   While primarily focusing on Gulf of Mexico exploration, Taurus did acquire
   in fiscal 1996 a 25 percent working interest in Sonat Exploration's
   exploratory efforts in the North Crowley field in Louisiana. This field also
   contains producing properties and was one of the four acquisitions made
   through Taurus's joint agreement with Sonat Exploration. The field contains
   8,000 gross undeveloped acres.

   COALBED METHANE OPERATIONS: Taurus's nonconventional gas strategy is to
   focus on operating the large projects in which it has a working interest and
   operating for others. Taurus is the operator of approximately 1,140 coalbed
   methane wells, including wells in a project owned by TECO Coalbed Methane,
   Inc., one of Taurus's joint venture partners in other coalbed methane
   projects. Under the terms of the TECO agreement, Taurus provides technical,
   administrative and operating services for a fee and receives additional
   compensation based on the project's profitability.

   Most of the gas produced from the coalbed methane wells in which Taurus has
   an interest is being sold under long-term contracts which provide markets
   for 100 percent of the wells' production capacity.

   ENVIRONMENTAL MATTERS: Taurus is subject to various environmental
   regulations. Management believes that Taurus is in compliance with currently
   applicable standards of the environmental agencies to which it is subject
   and that potential environmental liabilities, if any, are minimal. Also, to
   the extent Taurus has operating agreements with various joint venture
   partners, environmental costs, is any, would be shared proportionately.

- -  INTRASTATE GAS GATHERING AND TRANSMISSION

   Energen operates an intrastate gas pipeline and gathering system through its
   subsidiary, Basin Pipeline Corp. (Basin).  Basin's pipeline and gathering
   facilities primarily serve certain Taurus coalbed methane properties.

EMPLOYEES

The Company has 1,437 employees; Alagasco employs 1,296; Taurus employs 129;
and Energen's other subsidiaries employ 12.

ITEM 2.     PROPERTIES

The corporate headquarters of Energen, Alagasco and Taurus are located in
leased office space in Birmingham, Alabama.

The properties of Alagasco consist primarily of its gas distribution system,
which includes more than 8,800 miles of main, more than 9,600 miles of service
lines, odorization and regulation facilities, and customer meters. Alagasco
also has two liquefied natural gas facilities, eight division offices, nine
payment centers, six district offices, nine service centers, and other related
property and equipment, some of which are leased by Alagasco. For further
description of Alagasco's properties, see discussion under Item I--Business.

For a description of Taurus's oil and gas properties, see the discussion under
Item 1--Business.  Information concerning Taurus's production, reserves and
development is included in Note 12, Oil and Gas Producing Activities
(unaudited) to the Consolidated Financial Statements which is incorporated by
reference from the 1996 Annual Report to Stockholders and included in Part IV,
Item 14, Exhibit 13, herein. The proved reserve estimates are consistent with
comparable reserve estimates filed by Taurus with any federal authority or
agency.

ITEM 3.     LEGAL PROCEEDINGS

Energen, Alagasco and their 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 Alagasco.  It should be noted, however, that Energen,
Alagasco and their affiliates conduct business in Alabama and other
jurisdictions in which the magnitude and frequency of punitive damage awards
bearing little or no relation to culpability or actual damages continue to rise
making it increasingly difficult to predict litigation results.

ITEM 4.     SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

No matters were submitted to a vote of security holders during the fourth
quarter of 1996.

REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

TO THE BOARD OF DIRECTORS OF ALABAMA GAS CORPORATION:

We have audited the financial statements and the financial statement schedule
of Alabama Gas Corporation listed in the index on pages 17 and 18 of this Form
10-K. These financial statements and the financial statement schedule are the
responsibility of the Company's management.  Our responsibility is to express
an opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards 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.  An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation.  We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Alabama Gas Corporation as of
September 30, 1996 and 1995, and the  results of its operations and its cash
flows for each of the three years in the period ended September 30, 1996, in
conformity with generally accepted accounting principles. In addition, in our
opinion, the financial statement schedule referred to above, when considered in
relation to the basic financial statements taken as a whole, presents fairly,
in all material respects, the information required to be included therein.

NOTES TO FINANCIAL STATEMENTS

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

Alabama Gas Corporation (Alagasco), a wholly-owned subsidiary of Energen
Corporation, is the largest natural gas distribution utility in the State of
Alabama, serving customers primarily in central and north Alabama.  The
following is a description of its significant accounting policies and
practices.

A. 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 4.3 percent in 1996, 1995 and
   1994. The excess of total acquisition costs over book value of net assets
   acquired to date is included in utility plant ($23.2 million, net of $6.5 in
   accumulated amortization at September 30, 1996) and is being amortized on a
   straight-line basis over approximately 23 years.

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

C. 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.

D. REGULATORY ACCOUNTING:  Alagasco is subject to the provisions of Statement
   of Financial Accounting Standard (SFAS) No. 71, Accounting for the Effects
   of Certain Types of Regulation. In general, SFAS No. 71 allows utilities to
   capitalize or defer certain costs or revenues, based upon orders received
   from regulatory authorities, to be recovered from or refunded to customers
   in future periods.

E. INCOME TAXES: Alagasco files a consolidated income tax return with its
   parent. The consolidated income taxes are allocated to the appropriate
   subsidiaries using the separate return method. Deferred income taxes reflect
   the impact of temporary differences between the tax basis of assets and
   liabilities and their carrying amounts for financial reporting purposes and
   are measured in compliance with enacted tax laws. Investment tax credits
   have been deferred and are being amortized over the lives of the related
   assets.

F. CASH EQUIVALENTS: Alagasco includes highly liquid marketable securities and
   debt instruments purchased with a maturity of three months or less in cash
   equivalents.

G. ESTIMATES: The preparation of financial statements in conformity with
   generally accepted accounting principles 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.

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

As an Alabama utility, Alagasco is subject to regulation by the APSC which, in
1983, established the Rate Stabilization and Equalization (RSE) rate-setting
process. RSE was extended for the fourth time on October 7, 1996, for a
five-year period through January 1, 2002. Under the terms of that extension,
RSE will continue after January 1, 2002, unless, after notice to the Company
and a hearing, the Commission votes to either modify or discontinue its
operation.

Under RSE as extended, the APSC conducts quarterly reviews to determine, based
on Alagasco's projections and fiscal year-to-date performance, whether
Alagasco's return on equity for the fiscal year will be within the allowed
range of





                                       28
<PAGE>   29

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 fiscal 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. If the change in O&M expense per customer falls
within 1.25 percentage points above or below the Consumer Price Index For All
Urban Customers (index range), no adjustment is required. If, however, 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. Under RSE as extended, an $8.2 million annual increase
in revenue became effective December 1, 1995, and a $1.3 million decrease in
revenue became effective October 1, 1996.

Effective December 15, 1990, the APSC approved a temperature adjustment to
customers' monthly bills to remove the effect of departures from normal
temperature on Alagasco's earnings. The calculation is performed monthly, and
the adjustments to customers' bills are made in the same billing cycle the
weather variation occurs.

Alagasco's rate schedules for natural gas distribution charges contain a Gas
Supply Adjustment (GSA) rider, established in 1993, which permits the
pass-through to customers of changes in the cost of gas supply, including Gas
Supply Realignment (GSR) surcharges imposed by Alagasco's suppliers resulting
from changes in gas supply purchases related to the implementation of Federal
Energy Regulatory Commission (FERC) Order 636. On October 7, 1996, the APSC
issued an order providing for the refund to customers of approximately $17.1
million, including interest, of supplier refunds.  The Order provides that
refunds shall be returned to customers prior to January 31, 1997. These refunds
were collected from a variety of sources and most relate to the settlement of
rate case and FERC Order 636 proceedings of Southern Natural Gas Company
(Southern) as described herein.

On September 9, 1996, the APSC approved Alagasco's application to issue $25
million of debt, a portion of which will be used to fund the supplier refunds
discussed above. On June 12, 1995, Alagasco received approval from the APSC to
issue $50 million of debt, a portion of which was used to redeem all of
Alagasco's 9 percent debentures and 11 percent First Mortgage Bonds. In
connection with the early call of the redeemed debt, Alagasco paid an early
call premium of approximately $1.3 million. Because the APSC authorized
Alagasco to collect the early call premium through customer rates, a regulatory
asset of $1.3 million was recorded at September 30, 1995, and the amounts were
collected during fiscal 1996.

In accordance with APSC-directed regulatory accounting procedures, Alagasco in
1989 began returning to customers excess utility deferred taxes which resulted
from a reduction in the federal statutory tax rate from 46 percent to 34
percent using the average rate assumption method. This method provides for the
return to ratepayers of excess deferred taxes over the lives of the related
assets. In 1993 those excess taxes were reduced as a result of a federal tax
rate increase from 34 percent to 35 percent. Remaining excess utility deferred
taxes of $2.7 million are being returned to ratepayers over approximately 14
years. At September 30, 1996 and 1995, regulatory liabilities of $5 million and
$6 million, respectively, were included in the financial statements related to
income taxes.

FERC Regulation:  On March 15, 1995, Southern filed a comprehensive settlement
with the FERC in the form of a Stipulation and Agreement (the Settlement) to
resolve all issues in Southern's six pending rate cases, as well as to resolve
all GSR and transition cost issues resulting from the implementation of FERC
Order 636.  Alagasco was a supporting party to the Settlement. On April 11,
1996, the FERC issued its Order on Rehearing approving the Settlement with
minor modifications. The Settlement, as approved by FERC, provides for the
following: (1) the resolution of all cost of service and rate design issues in
Southern's six pending rate cases and the establishment of reduced rates for
the purpose of calculating rate case refunds; (2) the implementation of reduced
settlement rates for supporting parties commencing March 1, 1995; (3) the
resolution of all GSR and other transition cost issues resulting from FERC
Order 636; (4) lower GSR cost recovery through the reduction and earlier payout
of GSR costs; (5) a three-year moratorium on general rate increases; and (6)
the resolution and disposition of all rate case and GSR refunds for supporting
parties.  With respect to this last point, the Settlement provides that all
rate case refunds will be used to offset a portion of Southern's remaining GSR
liability. In addition, as a result of the recalculated GSR surcharges for the
period January 1, 1994, to February 28, 1995, Southern refunded over-collected
GSR costs. As a





                                       29
<PAGE>   30

result of this FERC order, Alagasco received other refunds based on contracts
with other suppliers whose prices were tied to Southern's rates. In total,
$17.1 million will be refunded to customers prior to January 31, 1997, and
includes amounts received from Southern, other suppliers and accrued interest.

The Settlement, as approved by FERC, resolves all issues relating to GSR and
other transition costs with respect to supporting parties. Alagasco estimates
that it has a remaining GSR liability of approximately $0.8 million to be paid
through December 1997 and approximately $1.4 million in other transition costs
to be paid through June 1998. Because these costs will be recovered in full
from its customers, Alagasco recorded regulatory assets of $2.2 million and $5
million at September 30, 1996 and 1995, respectively.

In the prior year, Alagasco deposited $37.6 million into an irrevocable trust
to complete an in-substance defeasance of its 9 percent debentures and 11
percent Series H First Mortgage Bonds. The funds in the trust, primarily
obtained through the issuance of medium-term notes and short-term borrowings,
were used solely to satisfy the principal, interest, and call premium of the
defeased debt. Accordingly, the debt and related accrued interest were excluded
from the 1995 balance sheet. No gain or loss was recorded in the financial
statements as the APSC granted Alagasco regulatory relief related to the income
statement impact of this defeasance.

The aggregate maturities of long-term debt for the next five years are as
follows:

5. EMPLOYEE BENEFIT PLANS
================================================================================

All information presented concerning retirement income and other benefit plans
includes other affiliates of Energen Corporation as well as Alagasco.

The Company has two defined benefit non-contributory pension plans which cover
a majority of the employees. Benefits are based on years of service and final
earnings. The Company's policy is to use the "projected unit credit" actuarial
method for funding and financial reporting purposes. The expense for the plan
covering the majority of employees (Plan A) for the years ended September 30,
1996, 1995 and 1994, was $412,000, $1,158,000, and $15,000, respectively. The
expense for the second plan covering employees under certain labor union
agreements (Plan B) for 1996, 1995 and 1994 was $197,000, $339,000, and
$555,000, respectively.

 The funded status of the plans is as follows:

</TABLE>

In 1995 the Company recognized a loss for special termination benefits of
$1,489,000 and a settlement gain of $430,000 pursuant to a voluntary early
retirement option offered to all salaried, non-officer employees of at least 58
years of age with a minimum of 5 years' service. Of the 55 eligible employees,
41 accepted.

The Company has deferred compensation plan agreements for certain key
executives providing for payments on retirement, termination, death or
disability. The deferred compensation expense under these agreements for 1996,
1995 and 1994 was $1,002,000, $808,000, and $461,000, respectively. At June
30, 1996 and 1995, the accumulated post-retirement benefit obligation related
to these agreements was $6,206,000 and $4,770,000, the projected benefit
obligation was $9,442,000 and $5,904,000, and the accrued post-retirement
benefit liability was $464,000 and $199,000.

In addition to providing pension benefits, the Company provides certain
post-retirement health care and life insurance benefits. Substantially all of
the Company's employees may become eligible for such benefits if they reach
normal retirement age while working for the Company. In a prior year, the
Company adopted SFAS No.106, Employers' Accounting for Post-retirement benefits
Other Than Pensions, with respect to the accrual of such costs for salaried
employees. During fiscal year 1994, the Company adopted SFAS 106 with respect
to such costs for employees under collective bargaining agreements. There was
no cumulative effect on the income statement resulting from the adoption of FAS
106, as the Company elected to amortize transition costs over a 20-year period.
On December 6, 1993, the APSC adopted an order which allows the Company to
recover all costs accrued under SFAS 106 through rates.

While the Company has not adopted a formal funding policy, all of its accrued
post-retirement liability was funded at year-end. The expense for salaried
employees for the years ended September 30, 1996, 1995, and 1994 was
$1,984,000, $2,271,000, and $2,319,000, respectively. The expense for union
employees was $4,076,000, $3,613,000, and $3,685,000 during 1996, 1995 and
1994, respectively. The "projected unit credit" actuarial method was used to
determine the normal cost and actuarial liability.

A reconciliation of the estimated status of the obligation is as follows:

=============================================================================================================
</TABLE>

The weighted average discount rate used in determining the accumulated
post-retirement benefit obligation was 7.75 percent and 7.5 percent in 1996 and
1995, respectively. The expected long-term rate of return on assets is 8.25
percent for both years, and the tax rate on investment income is assumed to be
40 percent. The weighted average health care cost trend rate used in
determining the accumulated post-retirement benefit obligation was 8 percent in
1996 and 1995. That assumption has a significant effect on the amounts
reported. For example, with respect to salaried employees, increasing the
weighted average health care cost trend rate by 1 percent would increase the
accumulated post-retirement benefit obligation by 2.4 percent and the net
periodic post-retirement benefit cost by 2.2 percent. For union employees,
increasing the weighted average health care cost trend rate by 1 percent would
increase the accumulated post-retirement benefit obligation by 7.5 percent and
the net periodic post-retirement benefit cost by 7.2 percent. The assumed
health care cost trend rate of 8 percent is not currently expected to change.
For pay-related life insurance benefits, the salary scale averages 5 percent.

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.
Expense for the years ended September 30, 1996, 1995, and 1994 was $370,000,
$155,000, and $150,000, respectively.

6. CAPITAL STOCK
================================================================================

Alagasco's authorized common stock consists of 3 million, $0.01 par value
common shares. At September 30, 1996 and 1995, 1,972,052 shares were issued and
outstanding. Alagasco is authorized to issue 120,000 shares of preferred stock
par value $0.01 per share, in one or more series. There are no shares
currently outstanding.

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 2008.
These contracts typically contain minimum demand charge obligations on the part
of Alagasco.

Alagasco has 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. During
1996, 1995 and 1994, Alagasco sold $8,831,000, $8,454,000 and $6,784,000,
respectively, of installment receivables. At September 30, 1996 and 1995, the
balance of these installment receivables was $16,964,000 and $15,618,000,
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.

ENVIRONMENTAL MATTERS:  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. A preliminary
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.

LEGAL MATTERS:  Alagasco is from time to time, party 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 financial position of Alagasco. It
should be noted, however, that Alagasco conducts business in Alabama and other
jurisdictions in which the magnitude and frequency of punitive damage awards
bearing little or no relation to culpability or actual damages continue to rise
making it increasingly difficult to predict litigation results. Various legal
proceedings arising in the normal course of business are currently in progress
and Alagasco has accrued a provision for estimated costs.

CONCENTRATION OF CREDIT RISK:  Natural gas distribution operating revenues and
related accounts receivable are generated from state-regulated utility natural
gas sales and transportation to more than 460,000 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, Alagasco believes that its provision for possible losses on
uncollectible accounts receivable is adequate for its credit loss exposure.

LEASE OBLIGATIONS:  Total payments related to leases included as operating
expense in the accompanying consolidated statements of income were $2,146,000,
$2,201,000, and $2,147,000 in 1996, 1995 and 1994, respectively. Minimum future
rental payments (in thousands) required after 1996 under leases with initial or
remaining noncancelable lease terms in excess of one year are as follows:

9. FINANCIAL INSTRUMENTS
================================================================================

The fair value of cash and cash equivalents and trade receivables (net of
allowance), approximates fair value due to the short maturity of the
instruments.

The fair value of fixed-rate long-term debt, including the current portion,
would be $121,567,000 at September 30, 1996.  The fair value was based on the
market value of debt with similar maturities and with interest rates currently
trading in the marketplace.

10.  RECENT PRONOUNCEMENTS OF THE FASB
================================================================================

In June 1995, the Financial Accounting Standards Board (FASB) issued SFAS No.
121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed Of.  This statement requires that long-lived assets be
reviewed for impairment whenever events or changes in the circumstances
indicate that the carrying amount for an asset may not be recoverable.  The
Company is required to adopt this Statement in its 1997 fiscal year, but, based
on known facts and circumstances, does not expect implementation to have a
material impact on the Company's financial statements.

In October 1995, SFAS No. 123, Accounting for Stock-Based Compensation, was
issued and also requires adoption by the Company in its fiscal year 1997.  SFAS
No. 123 establishes a fair value-based method of accounting for employee stock
options but allows companies to continue to follow the accounting treatment
prescribed by APB Opinion 25 with proper disclosure.  The Company has not yet
determined the method of accounting that it will follow for stock options but
does not expect that adoption of the requirements of SFAS No. 123 will have a
material impact on the Company's financial statements.

In June 1996, SFAS No. 125, Accounting for Transfers and Servicing of Financial
Assets and Extinguishments of Liabilities, was issued and provides accounting
and reporting standards for such transactions.  The Statement requires adoption
by the Company in its fiscal year 1998. Implementation of SFAS No. 125 is not
expected to have a material impact on the Company's financial statements.

11. SUMMARIZED QUARTERLY FINANCIAL DATA (Unaudited)
================================================================================

The following data summarize quarterly operating results. The Company's
business is seasonal in character and strongly influenced by weather
conditions.

                   EXECUTIVE RETIREMENT SUPPLEMENT AGREEMENT

                 THIS EXECUTIVE RETIREMENT SUPPLEMENT AGREEMENT made effective
as of _________________________ between Energen Corporation, a corporation (the
"Company"), and ___________________________ (the "Executive").

                                R E C I T A L S

                 The Executive has been employed by the Company and/or one or
more of its subsidiaries for a number of years, and as an employee has provided
capable executive leadership and management so as to enable the Company to
operate efficiently and effectively.  The Company and the Executive desire to
enter into this Agreement to provide for payment to the Executive and the
Executive's eligible spouse certain deferred compensation in the form of a
retirement supplement under certain circumstances.

                 NOW, THEREFORE, in consideration of the mutual promises of the
parties and the parties agree as follows:

                            ARTICLE 1 -- DEFINITIONS

         1.1     Agreement:  This document, including any attached schedules,
and any amendments to the same.

         1.2     Birthday:  An anniversary of the Executive's birth regardless
of whether the Executive survives to such anniversary.

         1.3     Cause:  Termination of employment by the Employer for "Cause"
shall mean TERMINATION based on any of the following:

                 (a)      The willful and continued failure by the Executive to
substantially perform such Executive's duties with the Employer (other than any
such failure resulting from such Executive's incapacity due to physical or
mental illness) after a written demand for substantial performance is delivered
to the Executive specifically identifying the manner in which such Executive
has not substantially performed such Executive's duties;

                 (b)      The engaging by the Executive in willful misconduct
which is demonstrably injurious to the Employer monetarily or otherwise; or

                 (c)      The conviction of the Executive of a felony.

         1.4     Code:  The Internal Revenue Code of 1986, as the same may

definition, A shall equal the average aggregate monthly basic pay from all
Employers for the 36 consecutive calendar months during which the Executive had
the highest average monthly basic pay out of the 60 calendar months immediately
preceding the Severance Date.  For purposes of this definition, B shall equal C
divided by 12, where C equals the average of the Executive's three highest
annual cash incentive awards under the Energen Annual Incentive Compensation
Plan (or successor annual cash incentive plan) for the five Company fiscal
years immediately preceding the earlier of (i) the fiscal year during which the
Severance Date occurs or (ii) the fiscal year during which the Executive's 61st
birthday occurs.

         1.7     Disability:  Total and permanent disability which entitles the
Executive to a disability benefit under the disability program sponsored and/or
maintained by the Company or the Executive's Employer.

         1.8     Eligibility Date:  The earliest date on which the Executive
could be entitled to receive the Executive's "primary insurance amount" or any
portion thereof under the federal Social Security Act as amended and in effect
on the Severance Date assuming that the Executive survives to such date.

         1.9     Employer:  The Company and any and all subsidiaries of the
Company and their respective successors and assigns.

         1.10    Lump Sum Election: An election made by the Executive pursuant
to Section 2.5 to receive a lump sum payment in lieu of the Supplemental
Retirement Benefit.

         1.11    Normal Retirement Date:  The first day of the month on or next
following the Executive's 60th Birthday; provided, however, if the Executive's
employment with an Employer continues beyond such date, the first day of the
month on or next following the date on which the Executive actually Retires
shall be  Normal Retirement Date.

         1.12    Present Value:  The present value of a benefit or benefits
determined using the discount rate used to determine the present value of
payments under Section 280G of the Code that is in effect at the date payment

equivalent benefits under the Retirement Plan at that date.

         1.13    Retire or Retirement:  Termination of employment (for whatever
reason including death) from all Employers after attaining age 60.

         1.14    Retirement Plan:  The "Energen Corporation Retirement Income

the Retirement Plan as in effect on the Severance Date and with the following
assumptions: (i) the Executive will accrue no Years of Service or partial Years
of Service under the Retirement Plan after the Severance Date; (ii) the first
payment to the Executive under the Retirement Plan will be made on the first

continuous employment with the Employer ending on the Executive's Severance 
Date.

         1.17    Service Factor:  If the Executive has 240 or more months of
Service then the Service Factor shall equal one (l).  At any time prior to the
time when the Executive has both earned a vested benefit under the Retirement
Plan and been continuously employed by an Employer for five years, the Service
Factor shall be 0.  Except as otherwise provided in the foregoing sentences,

Executive's "primary insurance amount" or any portion thereof at the later of
the Eligibility Date or the Normal Retirement Date assuming (i) that the
Executive has or will make appropriate and timely application for such benefit,
(ii) that no event has occurred or will occur by reason of which the amount of
such benefit has been or will be delayed, suspended or forfeited in whole or in
part, (iii) that if the Severance Date occurs prior to the Executive's 60th
Birthday, the Executive will continue to receive, until the Executive's 60th
Birthday, earnings at the Compensation rate taxable as wages by the Social
Security Act, and (iv) that, after the later to occur of the Executive's 60th
birthday or Normal Retirement Date, the Executive will have no further earnings
taxable as wages by the Social Security Act.

         1.20    Spouse:  The spouse to whom the Executive was married at the
date of the Executive's death and throughout the twelve-month period preceding
the Executive's Severance Date.

         1.21    Supplemental Retirement Benefit:  The benefit described in 
Section 2.2.

         1.22    Supplemental Spouse's Retirement Benefit:  The benefit
described in Section 2.3.





                                       3
<PAGE>   4

         1.23    The masculine gender shall be deemed to include the feminine;
the feminine to include the masculine; the singular to include the plural; and
the plural to include the singular in each case where appropriate.

                             ARTICLE 2 -- BENEFITS

         2.1     Eligibility.  The Executive and Spouse, as applicable, shall
be entitled to the benefits described in Sections 2.2 and 2.3; provided, that
no benefits shall be paid under this Agreement if (i) the Executive's
employment by an Employer is terminated for Cause, or (ii) the Severance Date
occurs for any reason before the Executive has both earned a vested benefit
under the Retirement Plan and been continuously employed by an Employer for
five years.

         2.2     Supplemental Retirement Benefit.  Subject to the other
provisions of this Agreement, commencing on the Executive's Normal Retirement
Date the Executive shall be entitled to receive a Supplemental Retirement
Benefit, which shall be payable monthly during the Executive's life with the
last payment being the payment made or due for the month in which the Executive
dies.  No benefit shall be payable under this Section 2.2 if the Executive dies
on or before the Normal Retirement Date.

                 The Supplemental Retirement Benefit shall be an amount equal
to the product of "A" multiplied by the Service Factor.  With respect to
Supplemental Retirement Benefit payments made for periods commencing prior to
the Eligibility Date, "A" shall equal the amount by which 60% of Compensation
exceeds the Retirement Plan Benefit.  With respect to Supplemental Retirement
Benefit payments made for periods commencing on or after the Eligibility Date,
"A" shall equal the amount by which 60% of Compensation exceeds the sum of the
Retirement Plan Benefit plus the Social Security Benefit.

                 If the Executive terminates employment due to Disability, (i)
the period that the Executive receives disability benefits from a disability
program sponsored or maintained by an Employer shall be treated as Service, and
(ii) the Supplemental Retirement Benefit shall not commence, and the Executive
shall not be deemed to have had a Severance Date, while the Executive is
receiving disability benefits payable from a disability program sponsored or
maintained by an Employer.  For purposes of this Section 2.2, reclassification
under the Retirement Plan from Disability Retirement to Retirement shall
constitute cessation of disability benefits.

         2.3     Supplemental Spouse's Retirement Benefit.

                 (a)      Subject to the other provisions of this Agreement,
following the Executive's death the surviving Spouse shall be entitled to a
Supplemental Spouse's Retirement Benefit, which shall be payable monthly
commencing on the later of (i) the first day of the month following the month
of the Executive's death or (ii) the first day of the month of the Executive's
55th Birthday, and continuing until the Spouse's death.  The Supplemental
Spouse's Retirement Benefit shall be an amount equal to 50% of the monthly
Supplemental Retirement Benefit which the Executive would have been entitled to
receive had death not occurred (based on Service through the





                                       4
<PAGE>   5

Severance Date and adjusting on the Eligibility Date); provided that if the
Executive's death occurs after the Severance Date, for each of the first three
months following the Executive's death the Supplemental Spouse's Retirement
Benefit shall be 100% of such amount.

                 (b)      If the Executive shall die while a Lump Sum Election
is in effect and while the Executive is still employed by the Employer, the
surviving Spouse shall receive in lieu of the benefit described in Section
2.3(a) above, a lump sum payment equal to one-half of the Present Value of the
Supplemental Retirement Benefit which the Executive would have been entitled to
receive based on Service through the Severance Date if the Executive had
survived to the Normal Retirement Date.  Such benefit shall be paid as promptly
as practicable after the Executive's death and, in all events, within
forty-five (45) days after the Executive's death.  For purposes of this Section
2.3(b), the determination of whether a Spouse has survived the Executive shall
be made in accordance with the provisions of Section 43-8-43 of the Code of
Alabama of 1975, as the same may from time to time be amended (as of the date
of this Agreement, Section 43-8-43 generally treats a person as having
predeceased a decedent unless the person survives the decedent by five days).

                 (c)      If the Executive shall die after the Severance Date,
while a Lump Sum  Election is in effect, and prior to receipt of the lump sum
payment, the lump sum benefit shall be payable to the Executive's estate and no
Supplemental Spouse's Retirement Benefit shall be payable to the surviving
Spouse, if any.

                 (d)      If the Executive dies after payment of a lump sum
pursuant to Section 2.5, no Supplemental Spouse's Retirement Benefit shall be
payable to the Executive's surviving Spouse, if any.

                 (e)      No benefit shall be payable following the Executive's
death except as provided in this Section 2.3.

         2.4     Spouse's Age.  If a Spouse who is entitled to a benefit under
this Article 2 is more than ten (10) years younger than the Executive, any
benefit payable to the Spouse under Section 2.3(a) (but not 2.3(b)) shall be
reduced by 1/20 for each full year of age difference more than ten (10).

         2.5     Payment Elections.

                          (a)     By checking the appropriate box on the
signature page of this Agreement, the Executive may elect to receive, in lieu
of the Supplemental Retirement Benefit to which the Executive will otherwise
become entitled under Section 2.2 hereof, a lump sum payment that is the
Present Value, as of the date payment is made, of such Supplemental Retirement
Benefit.  Such payment shall be made as promptly as practicable after the
Executive's Severance Date and, in all events, within forty-five (45) days
after such Severance Date.

                          (b)     By executing and filing with the Company a
form substantially identical to Exhibit I hereof, or such other form as the
Company may prescribe or approve, the





                                       5
<PAGE>   6

Executive may revoke an election made pursuant to paragraph (a) above or may
make any election which could be made pursuant to such paragraph, but any such
election or revocation of an election shall not become effective if the
Executive's Severance Date occurs within one year from the date such revocation
or election is made.


         2.6     Leave of Absence.  In the event the Executive is granted a
leave of absence, the Executive's employment shall be deemed to continue and
shall be treated as Service, during the period of such leave of absence unless
specifically determined to the contrary by the Committee.


              ARTICLE 3 -- AMENDMENT OR TERMINATION OF AGREEMENT

         3.1     Subject to Section 3.2 below, the Company reserves the right
to terminate this Agreement at any time by action of its Board of Directors or
the Committee, and the continuance of this Agreement is not guaranteed to the
Executive.

         3.2     No termination of this Agreement shall operate to reduce,
cancel or void the Company's obligation to pay benefits provided for under this
Agreement and accrued prior to the Severance Date.

         3.3     This Agreement may be amended by written instrument executed
by the Executive and by an officer of the Company thereunto duly authorized by
the Board of Directors of the Company.


                          ARTICLE 4 -- MISCELLANEOUS

         4.1     This Agreement shall under no circumstances be deemed to have
any effect upon the terms or conditions of employment of the Executive.  The
establishment and maintenance of this Agreement shall not be construed as
creating or modifying any contract between an Employer and the Executive nor is
it in lieu of any other benefits.  This Agreement shall under no circumstances
be deemed to constitute a contract of insurance.

         4.2     This Agreement shall not give the Executive the right to be
retained in the employ of an Employer or any right or interest hereunder other
than as specifically provided herein.

         4.3     Benefits under this Agreement shall not be subject in any
manner to anticipation, alienation, sale, transfer, assignment, pledge or
encumbrance by the Executive or the Spouse and any attempt to so transfer or
encumber the benefits shall be null and void.  Benefits under this Agreement
shall not be subject to or liable for the debts, contracts, liabilities,
engagements or torts of the Executive or of the Spouse nor may the same be
subject to attachment or seizure by any creditor of the Executive or the
Executive's spouse under any circumstances.





                                       6
<PAGE>   7

         4.4     In the event of the Executive's Retirement, Disability or
death, the Executive or the Executive's Spouse, as the case may be, should
notify the Committee promptly, and the Committee will then provide a Claimant's
statement form for completion which should be returned to the Committee
together with evidence of Disability or with an official death certificate, if
applicable.  In the event that any claim hereunder is denied, the Committee
will provide adequate notice in writing to the Executive or Spouse, setting
forth the specific reasons for such denial and, in addition, the Committee will
afford a reasonable opportunity for a full and fair review of those reasons.

                 IN WITNESS WHEREOF, the Company has caused this Agreement to
be executed by its duly authorized officer and the Executive has hereunto set
his/her hand and seal all as of the day and year first above written.

                        SEVERANCE COMPENSATION AGREEMENT


                 THIS AGREEMENT ("Agreement") is made and entered into as of
the ____ day of _________, 199_, by and between ENERGEN CORPORATION, an Alabama
corporation ("Energen"), and _______________________________, ("Executive").


                              W I T N E S S E T H:


                 WHEREAS, Executive is an effective and valuable employee of
Energen and/or one or more of its subsidiaries;

                 WHEREAS, Executive desires certain assurances with respect to
any change in control of Energen;

                 WHEREAS, Energen recognizes that the uncertainties involved in
a potential or actual change in control of Energen could result in the
distraction or departure of management personnel such as Executive to the
detriment of Energen and its shareholders; and

                 WHEREAS, Energen desires to lessen the personal and economic
pressure which a potential or actual change in control may impose on Executive
and thereby facilitate Executive's ability to bargain successfully for the best
interests of Energen's shareholders in the event of such a change in control;

                 NOW, THEREFORE, in consideration of the premises and the
mutual agreements herein contained, Energen and Executive hereby agree as
follows:

                          Section 1.  Definitions.  As used in this Agreement
the following words and terms shall have the following meanings:

                 (a)      "Applicable Period" means the period commencing with
the earliest date that a Change in Control occurs and ending on the last day of
the thirty-sixth calendar month following the calendar month during which such
Change in Control occurred.  Anything in this Agreement to the contrary
notwithstanding, if a Change in Control occurs, and if the Date of Termination
with respect to Executive's employment with Energen occurs prior to the date on
which the Change in Control occurs, and if it is reasonably demonstrated by
Executive that such termination of employment (i) was at the request of a third
party who has taken steps reasonably calculated to effect the Change in Control
or (ii) otherwise arose in connection with or in anticipation of the Change in
Control, then for all purposes of this Agreement the "Applicable Period" shall
be deemed to have commenced on the date immediately preceding the Date of

duties inconsistent with Executive's position, authority, duties,
responsibilities and status with Employer immediately prior to a Change in
Control, or a change in Executive's titles or offices as in effect immediately
prior to a Change in Control, or any removal of Executive from or any failure

to provide Executive with either the same fringe benefits (including retirement
benefits and paid vacations) as were provided to Executive immediately prior to
a Change in Control or a package of fringe benefits that, though one or more of

                          (1)     during a Window Period, any termination
(including Retirement) of Executive's employment, other than for Cause, death

                          (2)     during the Applicable Period but not during a

                                  (i)      any termination by Employer of 
Executive's employment other than for Cause,

                                  (ii)     a termination of Executive's
employment which Executive and Energen agree in writing will constitute a
Qualified Termination for purposes of this Agreement, and

                                  (iii)    a voluntary termination of
Executive's employment by Executive for Good Reason.

                 (p)      "Reasonable Compensation" shall have the same meaning
as provided for the term "reasonable compensation" in Section 280G(b)(4) of the
Code.

                 (q)      "Retirement" means termination of Executive's
employment (other than for Good Reason) by the Executive on or after
Executive's having reached age 60.

                 (r)      "Subsidiary" means any corporation, the majority of
the outstanding voting stock of which is owned directly or indirectly, by
Energen.

                 (s)      "Window Period" shall mean the 30-day period
immediately following the first anniversary of a Change in Control.

         Section 2.       Notice of Termination.  During any Applicable Period:

                 (a)      Any termination (other than for Retirement, death or
Disability) of Executive's employment, whether by Employer or Executive, shall
be communicated by the terminating party transmitting or sending the other
party a written notice ("Notice of





                                       5
<PAGE>   6

Termination") referencing this Agreement and, if such termination is for Cause
or Good Reason, indicating in reasonable detail the facts and circumstances
providing a basis for such termination.  The failure of Executive or Employer
to set forth in the Notice of Termination any fact or circumstance which
contributes to a showing of Good Reason or Cause shall not waive any right of
Executive or Energen hereunder or preclude Executive or Energen from asserting
or relying upon the omitted fact or circumstance in enforcing Executive's or
Energen's rights hereunder.

                 (b)      Subject to (c) below, such termination of Executive's
employment shall be effective upon delivery of a Notice of Termination or at
such later date as may be specified in the Notice of Termination.

                 (c)      In the event that each party delivers a Notice of
Termination, the Notice of Termination first delivered shall establish the
effective date of such Notice of Termination.

         Section 3.       Severance Payment.  In the event of a Qualified
Termination, then Executive shall, subject to the provisions of Sections 5 and
8 hereof, receive as severance pay an amount equal to his Compensation
multiplied by a factor of [1.5 or 2 or 2.5].  Subject to Section 5 hereof, any
severance payment to be made under this Section 3 shall be paid in one payment
and in full on or prior to the thirtieth day following the Date of Termination.

         Section 4.       Other Benefits.  Subject to Sections 5 and 8 hereof,
in the event of a Qualified Termination (other than Retirement), for a period
of twenty-four months commencing with the Date of Termination, Executive and
the Executive's family shall continue to be covered at the expense of Energen
by the same or substantially equivalent hospital, medical, dental, vision,
accident, disability and life insurance coverages as were provided to Executive
and the Executive's family by Employer immediately prior to the Change in
Control; provided, however, that if Executive becomes employed with another
employer and is eligible to receive benefits of the type described above from
such other employer, Energen's obligations under this Section 4 and the
benefits described herein shall be secondary to those provided by such other
employer.

         Section 5.       Limitation on Benefits.

                 (a)      Basic Rule.  Except as otherwise provided in
paragraph (c) below, any benefits payable or to be provided to the Executive by
Employer, whether pursuant to this Agreement or otherwise (including, without
limitation, Awards under the Energen Corporation 1992 or 1996 Long-Range
Performance Share Plans), which constitute Parachute Payments shall be modified
or reduced as provided in paragraph (b) below to the extent necessary so that
the benefits payable or to be provided to Executive under this Agreement that
constitute Parachute Payments, as well as any payments or benefits provided
outside of this Agreement that constitute Parachute Payments, shall not cause
Employer to have paid an Excess Parachute Payment.  All provisions of Section
280G of the Code, and the regulations (proposed, interim, or final) thereunder,
shall be taken into account in computing such amount, including making
appropriate adjustment to such calculation for amounts established to be
Reasonable Compensation.





                                       6
<PAGE>   7

                 (b)      Reductions.  In the event that the amount of any
Parachute Payment otherwise payable to or for the benefit of the Executive must
be modified or reduced to comply with paragraph (a) above, the Executive shall
direct which Parachute Payments are to be modified or reduced; provided,
however, that no increase in the amount of any payment or any change in the
timing of payment shall be made without the consent of Energen.

                 (c)      Optimization.  Prior to the first date any Parachute
Payment is due to be made, Energen shall, at its own expense, cause the
Independent Auditor to determine whether X exceeds Y, where

                          (i)     X is the total amount of Parachute Payments
that would be made to the Executive, whether pursuant to this Agreement or
otherwise, if the limitation provided for in paragraph (a) above were not
applied, reduced by the total amount of applicable federal, state, and local
income, payroll and excise taxes that would be payable by the Executive with
respect to such Parachute Payments, and

                          (ii)    Y is the total amount of Parachute Payments
that would be payable to the Executive, whether pursuant to this Agreement or
otherwise, if the limitation provided for in paragraph (a) above were applied,
reduced by the total amount of applicable federal, state and local income,
payroll and excise taxes that would be payable by the Executive with respect to
such Parachute Payments.

If X exceeds Y, then the limitation provided for in paragraph (a) above shall
not apply.  For purposes of making the determination provided for in this
paragraph (c), the Independent Auditor shall assume that all Parachute Payments
to be made to the Executive will be subject to federal income tax at the
maximum rate in effect at the time the determination is made unless the
Executive provides the Independent Auditor with evidence satisfactory to the
Independent Auditor that it is more probable than not that one or more
Parachute Payments will be taxable at a lower rate, or lower rates, in which
case the Independent Auditor shall assume that such Parachute Payments will be
taxed at the lower rate or rates.

                 (d)      Subsequent Payments.  As a result of various
incentive or other plans, Executive may be entitled to receive various
Parachute Payments over a period of several years.  In such event, the
Independent Auditor may need to update its Section 5(c) calculations one or
more times.  In the event that all or a portion of a Parachute Payment is not
made due to the limitations of this Section 5, Energen shall not be relieved of
liability for such amount but such Parachute Payment shall be deferred and
included in calculations with respect to subsequent Parachute Payments.

                 (e)      Overpayments and Underpayments.  As a result of
uncertainty in the application of section 280G of the Code at the time of
determinations by the Independent Auditor hereunder, uncertainties in the
valuation of future payments, and deferrals pursuant to Section 5(d), it is
possible that Parachute Payments will have been made by Energen which should
not have been made (an "Overpayment") or that additional Parachute Payments
which will not have been made by Energen could have been made (an
"Underpayment"), consistent in each case





                                       7
<PAGE>   8

with the other provisions of this Section 5.  In the event that the Independent
Auditor, based upon the assertion of a deficiency by the Internal Revenue
Service against Energen or the Executive which the Independent Auditor believes
has a high probability of success, determines that an Overpayment has been
made, such Overpayment shall be treated for all purposes as a loan to the
Executive which the Executive shall repay to Energen, together with interest at
the applicable federal rate provided for in section 7872(f)(2)(A) of the Code;
provided, however, that no amount shall be payable by the Executive to Energen
if and to the extent that such payment would not reduce the amount which is
subject to taxation under section 4999 of the Code.  In the event that the
Independent Auditor determines that an Underpayment has occurred, such
Underpayment shall promptly be paid or transferred by Energen to or for the
benefit of the Executive, together with interest at the applicable federal rate
provided for in section 7872(f)(2)(A) of the Code.

         Section 6.       No Obligation To Seek Further Employment; No Effect
on Other Benefits.

                 (a)      Executive shall not be required to seek other
employment, nor (except as otherwise provided under Section 4 with respect to
insurance coverages) shall the amount of any severance payment or other benefit
to be made or provided under this Agreement be reduced by any compensation or
benefit earned by Executive as the result of employment by another employer
after the Date of Termination, or otherwise.

                 (b)      Subject to Section 5 hereof, any severance payment or
benefit to be made or provided under this Agreement is in addition to all other
benefits, if any, to which Executive may be entitled under other agreements,
plans or programs of Energen.

         Section 7.       Continuing Obligations of Executive.  As a result of
and in connection with Executive's employment by Employer, Executive is
involved in a number of matters of strategic importance and value to Employer
including various projects, proceedings, planning processes, and negotiations.
Any number of these matters may be ongoing and continuing after the Date of
Termination.  In addition Employee is privy to proprietary and confidential
information of  Employer including without limitation, financial information
and projections, business plans and strategies, customer and vendor lists and
information, and oil and gas properties and prospects.  The Executive agrees as
follows:

                 (a)      Consulting Services.  For a period of three years
following the Date of Termination, Executive agrees to fully assist and
cooperate with Employer and its representatives (including outside auditors,
counsel and consultants) with respect to any matters with which the Executive
was involved during the course of employment with Employer, including being
available upon reasonable notice for interviews, consultation, and litigation
preparation.  Except as otherwise agreed by Executive, Executive's obligation
under this Section 7 (a) shall not exceed 80 hours during the first year and 20
hours during each of the following two years.  Such services shall be provided
upon request of Employer but scheduled to accommodate Executive's reasonable
scheduling requirements.  Executive shall receive no additional fee for such
services but shall be reimbursed all reasonable out-of-pocket expenses.





                                       8
<PAGE>   9

                 (b)      Non-Compete.  For a period of twelve months following
the Date of Termination, the Executive shall not Compete, (as defined below)
or assist others in Competing with the Employer.  For purposes of this
Agreement, "Compete" means (i) solicit in competition with Alabama Gas
Corporation ("Alagasco") any person or entity which was a customer of Alagasco
at the Date of Termination, (ii) offer to acquire any local gas distribution
system in the State of Alabama; or (iii) offer to acquire any coalbed methane
interest in the State of Alabama.  Employment by, or an investment of less than
one percent of equity capital in, a person or entity which Competes with
Employer does not constitute Competition by Executive so long as Executive does
not directly participate in, assist or advise with respect to such Competition.

                 (c)      Confidentiality.  Executive agrees that at all times
following the Date of Termination, Executive will not, without the prior
written consent of Energen, disclose to any person, firm or corporation any
confidential information of Employer which is now known to Executive or which
hereafter may become known to Executive as a result of Executive's employment
or association with Employer, unless such disclosure is required under the
terms of a valid and effective subpoena or order issued by a court or
governmental body; provided, however, that the foregoing shall not apply to
confidential information which becomes publicly disseminated by means other
than a breach of this Agreement.

         Section 8.       Board Resignation.  Energen shall have no obligation
under Sections 3 and 4 hereof if Executive shall not, promptly after the Date
of Termination and upon receiving a written request to do so, resign from each
officer and/or director position which Executive then holds with Energen and
any Subsidiary.

         Section 9.       Payment of Professional Fees and Expenses.  Energen
agrees to pay promptly as incurred, to the full extent permitted by law, all
legal, accounting and other professional fees and expenses which Executive may
reasonably incur (i) as a result of any contest (regardless of the outcome
thereof) by Energen, Executive or others of the validity or enforceability of,
or liability under, any provision of this Agreement or any guarantee of
performance thereof (including as a result of any contest by Executive about
the amount of any payment pursuant to this Agreement); plus in each case
interest on any delayed payment at the applicable Federal rate provided for in
Section 7872(f)(2)(A) of the Code; or (ii) as a result of any contest by a
taxing authority of Executive's tax treatment of any amounts received under
this or any other Employer agreement or plan to the extent such tax treatment
is consistent with the determinations made by the Independent Auditor under
Section 5.

         Section 10.      Term.  This Agreement shall terminate (except to the
extent of any unpaid or unfulfilled obligation with respect to a prior
termination of Executive's employment) on the first to occur of (i) any
termination of Executive's employment with Employer which does not constitute a
Qualified Termination or (ii) expiration of the Term.  The initial "Term" of
this Agreement shall be for a period of three years from the date hereof.  On
each anniversary of the date hereof, the Term shall automatically extend by one
year unless at least thirty days prior to such an anniversary Energen notifies
Executive that there will be no such extension, in which event the term shall
continue until the later to occur of (i) two years from such anniversary or
(ii) three years from the date of the most recent Change in Control, if any.

         Section 11.      Binding Effect; Successors.

                 (a)      This Agreement shall be binding upon and inure to the
benefit of Executive and Executive's personal representative and heirs, and
Energen and its successors and assigns including any successor organization or
organizations which shall succeed to substantially all of the business and
property of Energen, whether by means of merger, consolidation, acquisition of
assets or otherwise, including operation of law.

                 (b)      Without the prior consent of Energen, Executive may
not assign the Agreement, except by will or the laws of descent and
distribution.

         Section 12.      Notice.  For purposes of this Agreement, notices and
all other communications provided for in this Agreement shall be in writing and

or such other address as either party may have furnished to the other in
writing in accordance herewith, except that notices of change of address shall
be effective only upon receipt.

         Section 13.      Miscellaneous.  No provisions of this Agreement may
be modified, waived or discharged unless such waiver, modification or discharge
is agreed to in writing signed by Executive and Energen.  No waiver by either
party hereto at any time of any breach by the other party hereto of, or
compliance with, any condition or provision of this Agreement to be performed

MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS
OF OPERATIONS AND FINANCIAL CONDITION

RESULTS OF OPERATIONS

CONSOLIDATED NET INCOME

Energen Corporation's net income for the 1996 fiscal year was $21.5 million, or
$1.95 per share. This represented a 10 percent increase in per share earnings
over prior year net income of $19.3 million, or $1.77 per share, and resulted
from the continued financial and operating strength of Alabama Gas
Corporation's (Alagasco's) utility operations combined with significant growth
at Taurus Exploration Inc. (Taurus), Energen's nonregulated oil and gas
subsidiary. In 1994 Energen reported earnings of $23.8 million, or $2.19 per
share, including a one-time gain of $2 million, or 18 cents per share, for the
sale of propane assets and a reduction in investment in high temperature
combustion technology.

1996 VS 1995:  Alagasco achieved record net income for a sixth consecutive
year, increasing to $17.0 million over prior-year earnings of $15.7 million.
This 8 percent growth in income reflected the utility's ability to earn within
its allowed range of return on an increased level of equity. Fiscal 1995
earnings included a one-time after-tax charge of $503,000 resulting from a
voluntary early retirement program.

Taurus's net income grew 28.5 percent to $4.5 million on the strength of
increased oil and gas production, higher commodity sales prices and gains on
the sale of reserves; negatively influencing Taurus's earnings were increases
in production-related expenses, primarily depreciation, depletion and
amortization (DD&A) as well as increased interest and exploration expenses.

1995 VS 1994:  Alagasco's 1995 net income of $15.7 million increased 5.4
percent over 1994 net income of $14.9 million primarily due to the utility
earning for a full year on a higher level of equity generated by a $21 million
investment in underground storage working gas made in 1994; the utility
received a $10 million equity infusion from Energen to help fund the
investment. The one-time charge for the voluntary early retirement program in
fiscal 1995 partially offset this increase. Taurus earned net income of $3.5
million in 1995, a decrease of 46 percent from 1994. The major factor
negatively affecting Taurus's earnings was comparatively lower natural gas
commodity prices which affected Taurus's gas production revenues as well as
income from price-sensitive coalbed methane operating fees. Taurus's 1995
earnings also were negatively impacted by increased operating and DD&A expenses.

OPERATING INCOME

Consolidated operating income in 1996, 1995, and 1994 totaled $38.8 million,
$32.0 million and $35.3 million, respectively. In the current year, operating
income was influenced significantly by Taurus as it implemented Energen's
growth strategy and recognized a gain on the sale of reserves. Growth in
Alagasco's operating income was consistent with its increased level of equity.
Operating income in 1995 was impacted by lower natural gas commodity prices and
increased operating expense at Taurus.





                                                                              23

ALAGASCO:  Alagasco generates revenues through the sale and transportation of
natural gas. Shifts between transportation and sales gas can cause large
variations in natural gas revenues since the transportation rate does not
contain an amount representing the cost of gas. Alagasco's rate structure
allows similar margins on transported and sales gas; therefore, operating
income is not adversely affected. Weather also can cause variations in
revenues, but operating margins remain unaffected due to a real-time
temperature adjustment which allows Alagasco to adjust customer bills monthly
to reflect changes in usage due to departures from normal weather.

Alagasco's gross natural gas sales revenues totaled $326.8 million, $265.5
million, and $315.3 million in 1996, 1995, and 1994, respectively. Several
factors contributed to the 23 percent current-year increase in sales revenues
including the influence of significantly colder weather on total throughput and
higher commodity gas costs passed through to customers in rates. As a result of
Alagasco's temperature adjustment mechanism, however, the margins associated
with the colder weather were removed via an adjustment to customer bills. In
1995 pricing and weather had the opposite impact as lower prices and warmer
weather resulted in substantially lower revenues.

Alagasco's coldest winter in 18 years coupled with steady demand for commercial
and industrial sales and transportation volumes led to a new gas throughput
record of 111 Bcf in 1996. Residential sales volumes increased 27 percent in
the current year as weather in Alagasco's service area was 13 percent colder
than normal and 40 percent colder than the prior year. Sales and transportation
volumes to commercial and industrial customers totaled 76.5 Bcf in 1996 and 74
Bcf in 1995. While volumes to large customers remained relatively stable, small
commercial and industrial customers, more sensitive to weather, experienced
volume increases similar to residential customers. In 1995 residential volumes
decreased significantly due to weather which was 19 percent warmer than normal.
The addition of several large customers that year resulted in a 12 percent
increase in throughput to commercial and industrial customers.

Higher commodity gas cost and higher sales volumes resulting from the cold
weather in fiscal 1996 generated a 36 percent increase in cost of gas.
Conversely, lower prices and sales volumes in a warm year created the
significant decrease in 1995.

Several items contributed to the 5 percent increase in operations and
maintenance (O&M) expense at the utility in 1996.  Distribution expenses, which
include labor and maintenance costs, increased as a result of
colder-than-normal weather.  Secondly, to reflect its increased exposure from
higher commodity gas costs in accounts receivable, Alagasco increased its
provision for doubtful accounts. Thirdly, the utility increased its marketing
efforts over the previous year.  Partially offsetting these items was the
inclusion in the prior year and the resulting savings in the current year of
expense associated with an early retirement option. On a per customer basis,
the increase in O&M fell within the inflation-based cap established by the
Alabama Public Service Commission (APSC) as part of the utility's rate-setting
mechanism. In 1995 increased labor and related expenses, including the early
retirement charge, created the majority of the 7 percent increase.  As a result
of these costs, O&M expense per customer exceeded the cap and a portion of the
excess was returned to customers.

Consistent with growth in the utility's depreciable base, depreciation expense
rose 9.8 percent in 1996 and 8 percent in 1995. 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.

As discussed more fully in Note 2 to the Consolidated Financial Statements,
Alagasco is subject to regulation by the APSC.  On October 7, 1996, the APSC
issued an order to extend the Company's rate-setting mechanism for a five-year
period through January 1, 2002. Under the terms of that extension, RSE will
continue after January 1, 2002, unless, after notice to the Company and a
hearing, the Commission votes to either modify or discontinue its operation.

TAURUS:  Revenues from oil and gas production activities grew notably in the
first year of Taurus's aggressive growth strategy. Total production volumes
rose 60 percent to 16.1 Bcfe and included production from new acquisitions as
well as the addition of prior-year offshore discoveries. Natural gas
production, including coalbed methane, increased 43 percent to 12.3 Bcf.  Oil
volumes increased to 635 MBbl from 250 MBbl. Higher oil and gas prices
magnified the impact of increased production. Gas prices rose 14.5 percent to
$1.97 per Mcf, while oil prices increased 8 percent to $16.25 per barrel.
Reflected in those prices is the effect of Taurus hedging or placing under
contract 66 percent of its production at an average price of $2.00 per Mcf and
$18.30 per barrel, before consideration of any related basis differential.

Coalbed methane operating fees represent a percentage of net proceeds on
certain coalbed methane 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 in 1996 increased 14
percent to $3.8 million largely due to higher natural gas prices. Coalbed
methane consulting revenues decreased significantly in the current year as
Taurus completed several contracts.

Under Energen's aggressive growth strategy, Taurus may, in the ordinary course
of business, be involved in the sale of both developed and undeveloped
properties as a revenue source. With respect to developed properties, sales may
occur as a result of, but not limited to, disposing of marginal assets, and
accepting offers where the buyer gives greater value to a property than
Taurus's technical staff. The largest of several property sales in 1996
occurred in September when Taurus recorded a $3.2 million gain after selling
its working interest in reserves associated with PMC Reserve Acquisition 
Company.

</TABLE>

Weak natural gas prices had the greatest impact on production revenues in
fiscal 1995. Although Taurus hedged 65 percent of its natural gas production at
$2.06 per Mcf (before basis differential), the average sales price was $1.72
per Mcf, a decline of 9 percent from the previous year. Production revenues
also were affected by a 6 percent decrease in volumes resulting from lower
offshore production caused in part by the timing of production schedules. Oil
revenues benefitted from an increase in volumes and prices. Operating fees were
$1.1 million lower in 1995 primarily due to lower prices.  Consulting fees were
slightly higher due to the inclusion of revenues from a new contract. Also
included in 1995 revenues was a $769,000 gain associated with the buy out of a
long-term sales contract.

Operations expense increased $4.3 million in 1996 primarily due to Taurus's
acquisition and exploration strategy. Lease operating expense was significantly
higher because of current-year acquisitions plus an entire year's activity
related to fiscal 1995 acquisitions. Additionally, exploration expense
increased as a result of Taurus's expanded exploratory efforts. In 1995
operations expense increased $3 million primarily due to increased labor and
related expense, exploration expense and administrative expense.

DD&A expense rose $9.6 million from the prior year largely due to increased
production (16.1 Bcf in 1996 compared to 10.1 Bcf in 1995). In addition, the
average depletion rate of $1.15 per Mcf increased from $0.88 per Mcf in 1995 as
a result of reserve revisions and property write-downs. For 1995 the 8 percent
increase in DD&A was due largely to an increased average depletion rate ($0.78
per Mcf in 1994) associated with downward reserve revisions.

OTHER ACTIVITIES AND INTERCOMPANY ELIMINATIONS:  Operating income from Energen's
group of other activities did not vary significantly in 1996. The notable
decrease in 1995 was due almost exclusively to the absence of contribution from
propane activities following the sale of the Company's propane assets in June
1994. Intercompany eliminations relate to intercompany natural gas sales and
vary based on pricing and volumes.

NON-OPERATING ITEMS

CONSOLIDATED:  Fiscal 1996 interest expense increased $2.2 million primarily
due to the financing of Taurus's aggressive acquisition strategy, largely
through the use of the Company's short-term credit facilities. The average
daily outstanding balance under the short-term credit facilities was $38
million compared to $0.9 million in the prior year.  Also influencing the
current year was interest for a full year on $50 million of medium-term notes
(MTNs) issued in mid-1995 and, to a lesser degree, the issuance of $65 million
of MTNs in the fourth quarter of fiscal 1996. Interest expense in 1995
increased 4 percent over 1994 due primarily to the $50 million of MTNs
discussed above, offset to some degree by the repayment of $6.3 million of
notes payable and lower average short-term debt outstanding.

The decrease in total other income in the current year was largely due to the
inclusion of the amortization of the early call premium associated with the
redemption of debt in the prior year. Other income in 1995 decreased
significantly from 1994 as a result of pre-tax gains associated with the 1994
sale of the Company's propane assets ($2.1 million) and the sale of the
Company's investment in equity securities ($1.5 million).

The Company's effective tax rates in 1996, 1995, and 1994 were lower than
statutory federal tax rates primarily due to the recognition of nonconventional
fuel tax credits and the amortization of investment tax credits. Changes in
income tax expense in both years resulted primarily from changes in pre-tax
income. The Company's effective tax rates are expected to remain lower than
statutory federal rates through December 31, 2002, as tax credits generated
each year are expected to be fully recognized in the financial statements.

FINANCIAL POSITION AND LIQUIDITY

The Company's net cash from operating activities totaled $52.5 million, $60.9
million, and $34.3 million in 1996, 1995, and 1994, respectively. Colder
weather in 1996 impacted cash provided by operations through its effect on gas
supply costs as reflected in increased accounts receivable and payable and in
Alagasco's need to utilize and replenish its storage gas inventory.The receipt
of amounts from Southern Natural Gas Company  and other suppliers in settlement
of matters before the FERC (see Note 2 to the Consolidating Financial
Statements) positively affected cash flows in the current year. The increase in
operating cash flow in 1995 primarily is due to the net cash outflow of $23.5
million in 1994 to purchase storage gas at Alagasco. For both years, cash flow
was affected by fluctuations in other receivables and payables which are
generally the result of timing of payments.

Cash used in investing activities increased $84.5 million and $39.6 million in
1996 and 1995, respectively, largely due to the implementation of Energen's
diversified growth strategy.  In 1996 Taurus invested $108 million in property
acquisitions with development potential adding 178 Bcfe of proved developed and
undeveloped oil and gas reserves.  Current-year acquisitions include the $61
million purchase of 105 Bcf of coalbed methane reserves in Alabama. Prior-year
acquisitions totaled $16.9 million and added 26.8 Bcfe to proved reserves.
Taurus sold its entire working interest in reserves associated with the PMC
acquisition venture in 1996 resulting in cash proceeds of $13.1 million.
Proceeds of $13.4 million for the 1994 sale of both propane assets and equity
securities contributed to the increase in cash used in 1995.

Cash provided by financing activities totaled $80 million in 1996. The Company
issued $40 million of MTNs redeemable September 20, 2001, to September 15,
2026, with interest rates ranging from 7.1 percent to 8.1 percent. The Company
utilized





                                                                              27
<PAGE>   6

an additional $26.7 million in short-term credit facilities. Proceeds from
these issuances were used to finance the acquisition strategy at Taurus. Also
included in current-year financing activities were the proceeds from the
issuance of $25 million in Alagasco MTNs redeemable December 1, 1998, to
September 23, 2026, with interest rates ranging from 5.6 percent to 8 percent.
These proceeds will be used for customer refunds (see Note 2 to the
Consolidated Financial Statements), gas storage inventory replacement, and
facilities upgrade and acquisition. Cash provided by financing activities in
1995 was $15.9 million and included the issuance of $50 million in Alagasco
MTNs used to defease a portion of its long-term debt (see Note 3 to the
Consolidated Financial Statements).  In 1994 cash provided by financing
activities was $6.2 million and included the issuance of 550,000 shares of
Energen common stock and $50 million in Alagasco MTNs. Proceeds from these
issuances were used to fund the purchase of underground storage gas, redeem
other long-term debt, and fund additional capital needs.

CAPITAL EXPENDITURES

NATURAL GAS DISTRIBUTION:  During the last three fiscal years, Alagasco has
invested $124.4 million for capital projects: $95.9 million was spent on normal
expansion replacements and support of its distribution system; $14.6 million
was used in connection with the development of a new customer information
system; $6.5 million was used to improve gas availability; and $7.5 million was
used to purchase five municipal gas systems.

OTHER ACTIVITIES:  Capital expenditures by Energen's other activities totaled
$1.3 million in the last three fiscal years and primarily related to gathering
activities.

FUTURE CAPITAL RESOURCES AND LIQUIDITY

Utility capital expenditures could approximate $37.6 million in 1997 and
primarily represent additions for normal distribution system expansion.
Alagasco also will maintain an investment in storage working gas which is
expected to average approximately $24 million in 1997. Alagasco anticipates
funding these capital requirements through internally generated capital and the
utilization of short-term credit facilities.

The Company's strategy to dramatically grow its oil and gas exploration and
production subsidiary involves investing $400 million in the acquisition of
producing properties with development potential and $100 million in offshore
Gulf of Mexico exploration and development in the five-year period ending
September 30, 2000. During 1997 Taurus plans to invest $90 million in property
acquisitions and in the development of existing reserves and $20 million in
offshore exploration and development. It should be noted that Taurus's ability
to invest in property acquisitions will be significantly influenced by industry
trends as the producing property acquisition market has historically been
cyclical. To finance Taurus's investment program, the Company initially will
utilize short-term credit facilities of $156 million to supplement internally
generated cash flow, but long-term debt and equity will be issued for permanent
financing. During fiscal 1996, Energen filed a $250 million shelf registration
for debt and common stock. MTNs of $40 million were issued in September 1996,
and the Company plans to offer a combination of debt and equity during the
second fiscal quarter of 1997.

OUTLOOK

NATURAL GAS DISTRIBUTION:  A recent five-year extension of the utility's
rate-setting mechanism gives Alagasco the opportunity to continue earning a
return on average equity at year-end within a range of 13.15 percent to 13.65
percent.  Alagasco has previously implemented and will continue to utilize
flexible rate strategies to help compete effectively for large commercial and
industrial customer load in the deregulated marketplace and combat
fuel-switching and the threat of bypass of the distribution system. To
supplement traditional service area growth, the utility will continue to pursue
the acquisition of municipal gas systems in Alabama. Although residential
unbundling is being considered by some in the industry as a potential means to
improve efficiency and achieve market-driven pricing, Energen believes that
electric and gas utility market competition in Alabama already fulfills that
purpose for Alagasco; however, the Company will continue to assess the
advisability of residential unbundling.

EXPLORATION AND PRODUCTION:  Taurus's oil and gas production is expected to
increase 70 percent to more than 27 Bcfe in 1997. Seventy-two percent of
production is expected to come from currently producing wells; another 17
percent should be generated by existing wells coming on-line during the year;
and 11 percent is targeted from new acquisitions to be made in 1997. To hedge
its exposure to price fluctuations, Taurus has entered into futures contracts
or placed under sales contracts 70 percent of estimated gas production at an
average price of $2.18 per Mcf. Taurus also has hedged more than half of its
estimated oil production at $20.98 per barrel. Hedge prices do not reflect
basis differential. Coalbed methane production during 1997 is expected to
generate more than $6 million in tax credits.





                                                                              29

OTHER:  Certain of the statements set forth above contain forward-looking
information. Such statements involve risks and uncertainties, and there are
certain important factors that could cause actual results to differ materially
from those anticipated. Some of these important factors include, but are not
limited to, economic and competitive conditions, inflation, rates, regulatory
changes, financial market conditions, future business decisions, and other
uncertainties, all of which are difficult to predict and most of which are
beyond the control of the Company. 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, including many
factors beyond the control of the Company. As discussed in Note 12 to the
Consolidated Financial Statements, the total amount or timing of actual future
production may vary significantly from the amount of reserves disclosed. In the
event Taurus is unable to fully invest its planned acquisition expenditures,
operating revenues and proved reserves would be negatively affected. The
Company's results of operations and cash flows also could be affected by
changing oil and gas prices. Although Taurus makes use of futures contracts to
mitigate risk, fluctuations in oil and gas prices may affect the Company's
financial position.

RECENT PRONOUNCEMENTS OF THE FASB

During fiscal 1997, the Company is required to adopt two Statements issued in
1995 by the Financial Accounting Standards Board. Statement of Financial
Accounting Standard (SFAS) No. 121, Accounting  for the Impairment of
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of, requires
long-lived assets be reviewed for impairment whenever events or changes in
circumstances indicate that the carrying amount for an asset may not be
recoverable. Based on known facts and circumstances, its adoption is not
expected to have a material impact on the Company's financial statements. SFAS
No. 123,Accounting for Stock-Based Compensation, establishes a fair
value-based method of accounting for employee stock options but allows
companies to continue to follow the accounting treatment prescribed by APB
Opinion 25 with proper disclosure. The Company has not yet determined the
method of accounting that it will follow for stock options but does not expect
the requirements of SFAS No. 123 to have a material impact on the Company's
financial statements. In June 1996, SFAS No. 125, Accounting for Transfers and
Servicing of Financial Assets and Extinguishments of Liabilities, was issued
and provides accounting and reporting standards for such transactions. The
Company is required to adopt this Statement in fiscal 1998, and it is not
expected to have a material impact on the Company's financial statements.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

ENERGEN CORPORATION AND SUBSIDIARIES

1.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

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

A.       PRINCIPLES OF CONSOLIDATION

The accompanying financial statements include the accounts of the Company and
its subsidiaries, principally Alabama Gas Corporation (Alagasco) and Taurus
Exploration Inc. (Taurus), 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.       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 4.3 percent in 1996, 1995 and 1994. The excess
         of total  acquisition costs over book value of net assets acquired to
         date is included in utility plant ($23.2 million, net of $6.5 in
         accumulated amortization at September 30, 1996) and is being amortized
         on a straight-line basis over approximately 23 years.

         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
         Statement of Financial Accounting Standard (SFAS) No. 71, Accounting
         for the Effects of Certain Types of Regulation. In general, SFAS No.
         71 allows utilities to capitalize or defer certain costs or revenues,
         based upon orders received from regulatory authorities, to be
         recovered from or refunded to customers in future periods.

C.       OIL AND GAS PRODUCING ACTIVITIES

         PROPERTY AND RELATED DEPLETION: Taurus 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 is determined on
         field-by-field basis using the unit-of-production method based on
         proved reserves. A provision for anticipated abandonment and
         restoration costs at the end of a property's useful life is made
         through depreciation expense.

         HEDGING:  Taurus periodically enters into futures contracts to hedge
         its exposure to price fluctuations on oil and gas production. Gains
         and losses on futures contracts are recorded in the income statement
         as the hedged volumes are recognized.





36
<PAGE>   15

         OPERATING REVENUE:  Taurus 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, and overproduction liabilities are established only when
         it is estimated that a property's overproduced volumes exceed the net
         share of remaining reserves for such property. The Company has no
         significant production imbalances at September 30, 1996. Gains and
         losses on the sale of property in the ordinary course of business are
         classified as operating revenue; current year gains of $3.9 million
         were recorded.

D.       INCOME TAXES

The Company's deferred income taxes reflect the impact of temporary differences
between the tax basis of assets and liabilities and their carrying amounts for
financial reporting purposes and are measured in compliance with enacted tax
laws. Investment tax credits have been deferred and are being amortized over
the lives of the related assets.

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.       ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles 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 reserve volumes and the related present value of
estimated future net revenues therefrom (see Note 12).

2. REGULATORY MATTERS

As an Alabama utility, Alagasco is subject to regulation by the APSC which, in
1983, established the Rate Stabilization and Equalization (RSE) rate-setting
process. RSE was extended for the fourth time on October 7, 1996, for a
five-year period through January 1, 2002. Under the terms of that extension,
RSE will continue after January 1, 2002, unless, after notice to the Company
and a hearing, the Commission votes to either modify or discontinue its
operation.

Under RSE as extended, the APSC conducts quarterly reviews to determine, based
on Alagasco's projections and fiscal year-to-date performance, whether
Alagasco's return on equity for the fiscal 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 fiscal 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. If the change in O&M expense per
customer falls within 1.25 percentage points above or below the Consumer Price
Index For All Urban Customers (index range), no adjustment is required. If,
however, 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. Under RSE as extended, an $8.2
million annual increase in revenue became effective December 1, 1995, and a
$1.3 million decrease in revenue became effective October 1, 1996.

Effective December 15, 1990, the APSC approved a temperature adjustment to
customers' monthly bills to remove the effect of departures from normal
temperature on Alagasco's earnings. The calculation is performed monthly, and
the adjustments to customers' bills are made in the same billing cycle the
weather variation occurs.

Alagasco's rate schedules for natural gas distribution charges contain a Gas
Supply Adjustment (GSA) rider, established in 1993, which permits the
pass-through to customers of changes in the cost of gas supply, including Gas
Supply Realignment (GSR) surcharges imposed by Alagasco's suppliers resulting
from changes in gas supply purchases related to the implementation of  Federal
Energy Regulatory Commission (FERC) Order 636. On October 7, 1996, the APSC
issued an order providing for the refund to customers of approximately $17.1
million, including interest, of supplier refunds.  The





                                                                              37
<PAGE>   16

Order provides that refunds shall be returned to customers prior to January 31,
1997. These refunds were collected from a variety of sources and most relate to
the settlement of rate case and FERC Order 636 proceedings of Southern Natural
Gas Company (Southern) as described herein.

On September 9, 1996, the APSC approved Alagasco's application to issue $25
million of debt, a portion of which will be used to fund the supplier refunds
discussed above. On June 12, 1995, Alagasco received approval from the APSC to
issue $50 million of debt, a portion of which was used to redeem all of
Alagasco's 9 percent debentures and 11 percent First Mortgage Bonds. In
connection with the early call of the redeemed debt, Alagasco paid an early
call premium of approximately $1.3 million. Because the APSC authorized
Alagasco to collect the early call premium through customer rates, a regulatory
asset of $1.3 million was recorded at September 30, 1995, and the amounts were
collected during fiscal 1996.

In accordance with APSC-directed regulatory accounting procedures, Alagasco in
1989 began returning to customers excess utility deferred taxes which resulted
from a reduction in the federal statutory tax rate from 46 percent to 34
percent using the average rate assumption method. This method provides for the
return to ratepayers of excess deferred taxes over the lives of the related
assets. In 1993 those excess taxes were reduced as a result of a federal tax
rate increase from 34 percent to 35 percent. Remaining excess utility deferred
taxes of $2.7 million are being returned to ratepayers over approximately 14
years. At September 30, 1996 and 1995, regulatory liabilities of $5 million and
$6 million, respectively, were included in the financial statements related to
income taxes.

FERC REGULATION:  On March 15, 1995, Southern filed a comprehensive settlement
with the FERC in the form of a Stipulation and Agreement (the Settlement) to
resolve all issues in Southern's six pending rate cases, as well as to resolve
all GSR and transition cost issues resulting from the implementation of FERC
Order 636.  Alagasco was a supporting party to the Settlement. On April 11,
1996, the FERC issued its Order on Rehearing approving the Settlement with
minor modifications. The Settlement, as approved by FERC, provides for the
following: (1) the resolution of all cost of service and rate design issues in
Southern's six pending rate cases and the establishment of reduced rates for
the purpose of calculating rate case refunds; (2) the implementation of reduced
settlement rates for supporting parties commencing March 1, 1995; (3) the
resolution of all GSR and other transition cost issues resulting from FERC
Order 636; (4) lower GSR cost recovery through the reduction and earlier payout
of GSR costs; (5) a three-year moratorium on general rate increases; and (6)
the resolution and disposition of all rate case and GSR refunds for supporting
parties.  With respect to this last point, the Settlement provides that all
rate case refunds will be used to offset a portion of Southern's remaining GSR
liability. In addition, as a result of the recalculated GSR surcharges for the
period January 1, 1994, to February 28, 1995, Southern  refunded over-collected
GSR costs. As a result of this FERC order, Alagasco received other refunds
based on contracts with other suppliers whose prices were tied to Southern's
rates. In total, $17.1 million will be refunded to customers prior to January
31, 1997, and includes amounts received from Southern, other suppliers and
accrued interest.

The Settlement, as approved by FERC, resolves all issues relating to GSR and
other transition costs with respect to supporting parties. Alagasco estimates
that it has a remaining GSR liability of approximately $0.8  million to be paid
through December 1997 and approximately $1.4 million in other transition costs
to be paid through June 1998. Because these costs will be recovered in full
from its customers, Alagasco recorded regulatory assets of $2.2 million and $5
million at September 30, 1996 and 1995, respectively.

In the prior year, the Company deposited $37.6 million into an irrevocable
trust to complete an in-substance defeasance of Alagasco's 9 percent debentures
and 11 percent Series H First Mortgage Bonds. The funds in the trust, primarily
obtained through the issuance of medium-term notes and short-term borrowings,
were used solely to satisfy the principal, interest, and call premium of the
defeased debt. Accordingly, the debt and related accrued interest were excluded
from the 1995 consolidated balance sheet. No gain or loss was recorded in the
financial statements as the APSC granted Alagasco regulatory relief related to
the income statement impact of this defeasance.

The aggregate maturities of long-term debt for the next five years are as
follows:

The Company is subject to various restrictions on the payment of dividends.
Under its 8  percent debentures, the most restrictive provision states that
dividends or other distributions with respect to common stock may not be made
unless the Company maintains a minimum consolidated tangible net worth of $80
million; at September 30, 1996, Energen had a tangible net worth of 
$188,178,000.

The Company and Alagasco have short-term credit lines and other credit
facilities of $156  million available to either entity for working capital
needs. The following is a summary of information relating to notes payable to

No valuation allowance with respect to deferred taxes is deemed necessary as
the Company anticipates generating adequate future taxable income to realize
the benefits of all deferred tax assets on the consolidated balance sheet. As
of September 30, 1996, the amount of minimum tax credit which can be carried
forward indefinitely to reduce future regular tax liability is $16,379,000.

5. EMPLOYEE BENEFIT PLANS

The Company has two defined benefit non-contributory pension plans which cover
a majority of the employees. Benefits are based on years of service and final
earnings. The Company's policy is to use the "projected unit credit" actuarial
method for funding and financial reporting purposes. The expense for the plan
covering the majority of employees (Plan A) for the years ended September 30,
1996, 1995 and 1994, was $412,000, $1,158,000, and $15,000, respectively. The
expense for the second plan covering employees under certain labor union
agreements (Plan B) for 1996, 1995 and 1994 was $197,000, $339,000, and
$555,000, respectively.

The funded status of the plans is as follows:

At September 30, 1996, for both plans the discount rate used to measure the
projected benefit obligation was 7.75 percent, and the expected long-term rate
of return on plan assets was 8.25 percent. The annual rate of salary increase
for the salaried plan was 5.75 percent. At September 30, 1995, for both plans
the discount rate used to measure the projected benefit obligation was 7.5
percent, and the expected long-term rate of return on plan assets was 8.25
percent.  The annual rate of salary increase for the salaried plan was 5.5
percent.

- -----------------------------------------------------------------------------------------------------------------------
</TABLE>

In 1995 the Company recognized a loss for special termination benefits of
$1,489,000 and a settlement gain of $430,000 pursuant to a voluntary early
retirement option offered to all salaried, non-officer employees of at least 58
years of age with a minimum of 5 years' service. Of the 55 eligible employees,
41 accepted.

The Company has deferred compensation plan agreements for certain key
executives providing for payments on retirement, termination, death or
disability. The deferred compensation expense under these agreements for 1996,
1995 and 1994 was $1,002,000, $808,000, and $461,000, respectively.  At June
30, 1996 and 1995, the accumulated post-retirement benefit obligation related
to these agreements was $6,206,000  and $4,770,000, the projected benefit
obligation was $9,442,000 and $5,904,000, and the accrued post-retirement
benefit liability was $464,000 and $199,000.

In addition to providing pension benefits, the Company provides certain
post-retirement health care and life insurance benefits. Substantially all of
the Company's employees may become eligible for such benefits if they reach
normal retirement age while working for the Company. In a prior year, the
Company adopted SFAS No.106, Employers' Accounting for Post-retirement benefits
Other Than Pensions, with respect to the accrual of such costs for salaried
employees.  During fiscal year 1994, the Company adopted SFAS 106 with respect
to such costs for employees under collective bargaining agreements.  There was
no cumulative effect on the income statement resulting from the adoption of FAS
106, as the Company elected to amortize transition costs over a 20-year period.
On December 6, 1993, the APSC adopted an order which allows the Company to
recover all costs accrued under SFAS 106 through rates.

While the Company has not adopted a formal funding policy, all of its accrued
post-retirement liability was funded at year-end. The expense for salaried
employees for the years ended September 30, 1996, 1995, and 1994 was
$1,984,000, $2,271,000, and $2,319,000, respectively. The expense for union
employees was $4,076,000, $3,613,000, and $3,685,000 during 1996, 1995 and
1994, respectively. The "projected unit credit" actuarial method was used to
determine the normal cost and actuarial liability.

A reconciliation of the estimated status of the obligation is as follows:

</TABLE>

The weighted average discount rate used in determining the accumulated
post-retirement benefit obligation was 7.75 percent and 7.5 percent in 1996 and
1995, respectively. The expected long-term rate of return on assets is 8.25
percent for both years, and the tax rate on investment income is assumed to be
40 percent. The weighted average health care cost trend rate used in
determining the accumulated post-retirement benefit obligation was 8 percent in
1996 and 1995. That assumption has a significant effect on the amounts
reported. For example, with respect to salaried employees, increasing the
weighted average health care cost trend rate by 1 percent would increase the
accumulated post-retirement benefit obligation by 2.4 percent and the net
periodic post-retirement benefit cost by 2.2 percent. For union employees,
increasing the weighted average health care cost trend rate by 1 percent would
increase the accumulated post-retirement benefit obligation by 7.5 percent and
the net periodic post-retirement benefit cost by 7.2 percent. The assumed
health care cost trend rate of 8 percent is not currently expected to change.
For pay-related life insurance benefits, the salary scale averages 5 percent.

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.
Expense for the years ended September 30, 1996, 1995, and 1994 was $370,000,
$155,000, and $150,000, respectively.

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
Plan, 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 September 30, 1996, 352,177 common shares were
reserved for issuance under the ESP. Expense associated with Company
contributions to the ESP was $2,902,000, $2,944,000, and $2,772,000 for 1996,
1995 and 1994, respectively.

In 1992 the Company adopted the Energen Corporation 1992 Long-Range
Performance Plan which provides for the award of up to 500,000 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, 350,000 shares have been
reserved for issuance. Under the Plan, 62,630, 56,430, and 49,120 performance
units were awarded in 1996, 1995 and 1994, respectively, leaving 243,326
performance units available for award at September 30, 1996. The Company
recorded expense of $1,223,000, $1,628,000, and $939,000 for 1996, 1995 and
1994, respectively, under the Plan.

The Restricted Stock Incentive Plan of Energen Corporation, adopted in 1984,
provided for the award of common stock to eligible participants. Stock awarded
under the Plan is subject to certain restrictions against sale or pledge.
Pursuant to its terms, the Plan terminated effective January 1994 subject to
completion of restriction periods applicable to previously





                                                                              43

awarded shares. Under the Plan, no common shares were awarded in 1996, 1995, or
1994. Expense of $50,000, $121,000, and $218,000 was charged during 1996, 1995
and 1994, respectively, under this Plan.

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.  Accordingly, 750,000 shares were added to the Plan. As of
September 30, 1996, 830,908 common shares were reserved under this Plan.

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 Plan provide for
purchase of the Company's common stock at not less than the fair market value
on the date the option is granted.  Under the Plan, 270,000 shares of the
Company's common stock have been reserved for issuance. Options were granted in
1996 and 1995 with dividend equivalents.  Options expire 10 years from the date
of grant. Transactions under the Plan are summarized as follows:

</TABLE>

In 1992 the Company adopted the Energen Corporation 1992 Directors Stock Plan
to enable the Company to pay part of the compensation of its non-employee
directors in shares of the Company's common stock. Under the Plan, 4,322,
3,829, and 3,515 shares were issued in 1996, 1995 and 1994, respectively,
leaving 85,272 shares reserved for issuance at September 30, 1996.

The Company has adopted a Shareholder Rights Plan intended to protect
shareholders from coercive or unfair takeover tactics. Under certain
circumstances, shareholders have the right to acquire the Company's Series A
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 (dated July 27, 1988, and amended February 28, 1990)
between the Company and its Rights Agent. Under the plan, two-thirds of a right
is associated with each outstanding share of Common Stock.  Rights outstand-
ing under the Shareholder Rights Plan at September 30, 1996 and 1995, were
convertible into 74,418 and 72,734 shares, respectively, of Series A Junior
Participating Preferred Stock (1/100 share of preferred stock for each full
right) subject to adjustment upon the occurrence of certain take-over related
events.  No rights were exercised or exercisable at either period. The price at
which the rights would be exercised is $80 per right, subject to adjustment
upon the occurrence of certain take-over related events. In general, in the
absence of certain takeover-related events, as described in the Plan, the
rights may be redeemed prior to their July 27, 1998, expiration for $0.02 per
right.

7. COMMITMENTS AND CONTINGENCIES

CONTRACTS AND AGREEMENTS:  The Company has various firm gas supply and firm gas
transportation contracts which expire at various dates through the 2008. These
contracts typically contain minimum demand charge obligations on the part of
the Company.

Taurus has entered into a three-and-one-half-year agreement with Sonat
Exploration Company. Under the agreement, which extends through calendar year
1998, Taurus expects to spend between $25 and $50 million annually as its
proportionate share of acquisitions made through Sonat Exploration's reserve
acquisition program.

The Company has 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. During
1996, 1995 and 1994, the Company sold $8,831,000, $8,454,000 and $6,784,000, 
respectively, of installment receivables.  At





44
<PAGE>   23

September 30, 1996  and  1995, the balance of these installment receivables was
$16,964,000 and $15,618,000, respectively. Receivables sold under this
agreement are considered financial instruments with off-balance sheet risk.
The Company's exposure to credit loss in the event of non-performance by
customers is represented by the balance of installment receivables.

During 1996, Taurus entered into a sales contract covering the production from
its current year coalbed methane acquisition. The contract, in part, provides
for variable and fixed prices with fixed prices of $2.37 per Mcf and $2.02 per
Mcf for fiscal years 1997 and 1998, respectively. Taurus's net production
subject to the fixed prices is estimated at 4 Bcf per year. Taurus's gross
estimated production committed to the fixed price component of the contract
approximates 80 percent of the total anticipated production from the
acquisition during the next two fiscal years.

HEDGING: Revenues from the Company's oil and gas subsidiary are primarily the
result of sales of natural gas and oil production. Market prices of natural gas
and oil may fluctuate and significantly impact operating results. To mitigate
this risk, Taurus periodically enters into futures contracts to hedge its
exposure to price reductions on its oil and gas production. Under this program,
Taurus has entered into futures contracts for the sale of 11.5 Bcf of its
fiscal 1997 gas production at an average contract price of $2.12 per Mcf and
for the sale of 558 MBbl of its fiscal 1997 oil production at an average
contract price of $20.98 per barrel. Hedge prices do not include basis
differential.

ENVIRONMENTAL MATTERS: 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. A preliminary
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.

Taurus is subject to various environmental regulations. Management believes
that Taurus is in compliance with the currently applicable standards of the
environmental agencies to which it is subject and that potential environmental
liabilities, if any, are minimal. Also, to the extent Taurus has operating
agreements with various joint venture partners, environmental costs, if any,
would be shared proportionately.

LEGAL MATTERS: Energen, Alagasco, and their 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 Alagasco. It should be noted, however, that
Energen, Alagasco and their affiliates conduct business in Alabama and other
jurisdictions in which the magnitude and frequency of punitive damage awards
bearing little or no relation to culpability or actual damages continue to rise
making it increasingly difficult to predict litigation results. Various legal
proceedings arising in the normal course of business are currently in progress
and the Company has accrued a provision for estimated costs.

CONCENTRATION OF CREDIT RISK: Natural gas distribution operating revenues and
related accounts receivable are generated from state-regulated utility natural
gas sales and transportation to more than 460,000 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.

Revenues and related accounts receivable from exploration and production
operations are generated primarily from the sale of produced natural gas and
oil. This industry concentration has the potential to impact the Company's
overall exposure to credit risk, either positively or negatively, in that the
customers may be similarly affected by changes in economic, industry, or other
conditions. The Company is not aware of any significant credit risks which have
not been recognized in the provision for doubtful accounts.

LEASE OBLIGATIONS: Total payments related to leases included as operating
expense in the accompanying consolidated statements of income were $3,050,000,
$3,035,000, and $2,986,000 in 1996, 1995 and 1994, respectively. Minimum future
rental payments (in thousands) required after 1996 under leases with initial or
remaining noncancelable lease terms in excess of one year are as follows:

9. 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 fixed-rate long-term debt, including the current portion,
would be $194,497,000 at September 30, 1996.  The fair value was based on the
market value of debt with similar maturities and with interest rates currently
trading in the marketplace.

10.  RECENT PRONOUNCEMENTS OF THE FASB

In June 1995, the Financial Accounting Standards Board (FASB) issued SFAS No.
121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed Of.  This statement requires that long-lived assets be
reviewed for impairment whenever events or changes in the circumstances
indicate that the carrying amount for an asset may not be recoverable.  The
Company is required to adopt this Statement in its 1997 fiscal year, but, based
on known facts and circumstances, does not expect implementation to have a
material impact on the Company's financial statements.

In October 1995, SFAS No. 123, Accounting for Stock-Based Compensation, was
issued and also requires adoption by the Company in its fiscal year 1997.  SFAS
No. 123 establishes a fair value-based method of accounting for employee stock
options but allows companies to continue to follow the accounting treatment
prescribed by APB Opinion 25 with proper disclosure.  The Company has not yet
determined the method of accounting that it will follow for stock options but
does not expect that adoption of the requirements of SFAS No. 123 will have a
material impact on the Company's financial statements.

In June 1996, SFAS No. 125, Accounting for Transfers and Servicing of Financial
Assets and Extinguishments of Liabilities, was issued and provides accounting
and reporting standards for such transactions.  The Statement requires adoption
by the Company in its fiscal year 1998. Implementation of SFAS No. 125 is not
expected to have a material impact on the Company's financial statements.

12. OIL AND GAS PRODUCING ACTIVITIES (Unaudited)

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

LEASE ACQUISITION COSTS are costs incurred to lease or otherwise acquire a
property.

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

The Company also had a revenue interest only in an additional 236 gross wells.
There were 103 gross wells with multiple completions with the Company's
interest being an equivalent of 49.3 wells. All wells and acreage are located
in the United States, onshore and offshore, with the majority of the net
undeveloped acreage located in the Gulf Coast region.

OIL AND GAS PRODUCING ACTIVITIES  The calculation of proved reserves are made
pursuant to rules prescribed by the Securities and Exchange Commission. Such
rules, in part, require that only proved categories of reserves be disclosed
and that reserves and associated values be calculated using current prices and
costs. Changes to current prices and costs might 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 learned. Accordingly, the amount of
actual future production may vary significantly from the amount of reserves
disclosed. See Note 7 for pricing information regarding the hedging activities
of the Company. The proved reserves are located in the United States, both
onshore and offshore, and are as follows:

of $3.9 million.

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.

Production of coalbed methane from wells drilled prior to January 1, 1993,
qualifies through December 31, 2002, for federal income tax credits under
Section 29 of the Internal Revenue Code of 1986, as amended. The tax credit
currently approximates $1 per Mcf of qualifying production. Accordingly, a
significant portion of the value of proved coalbed methane reserves is
associated with this tax credit.

MANAGEMENT'S RESPONSIBILITY FOR FINANCIAL REPORTING

The accompanying consolidated financial statements and related notes of Energen
Corporation were prepared by management, which has the primary responsibility
for the integrity of the financial information therein. The statements were
prepared in conformity with generally accepted accounting principles
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 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 September
30, 1996, management was aware of no material weaknesses in Energen's system of
internal accounting controls.

The consolidated financial statements have been audited by the Company's
independent certified public accountants, whose opinion is expressed elsewhere
on this page. Their audit was conducted in accordance with generally accepted
auditing standards; and, in connection therewith, they obtained an
understanding of the Company's system 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 consolidated 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 public accountants and representatives of
management to discuss matters regarding internal accounting controls, auditing
and financial reporting.

REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

TO THE SHAREHOLDERS OF ENERGEN:

We have audited the accompanying consolidated balance sheets of Energen
Corporation and Subsidiaries as of September 30, 1996 and 1995, and the related
consolidated statements of income, shareholders' equity and cash flows for each
of the three years in the period ended September 30, 1996. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards 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. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

 In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Energen
Corporation and Subsidiaries as of September 30, 1996 and 1995, and the
consolidated results of their operations and cash flows for each of the three
years in the period ended September 30, 1996, in conformity with generally
accepted accounting principles.

GLOSSARY

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

BYPASS:  Obtaining service from a new gas supplier without utilizing the
facility of the former supplier.

DEVELOPMENT COSTS:  Costs necessary to gain access to, prepare and equip
wells drilled to produce proved oil and gas reserves following discovery.

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

FEDERAL ENERGY REGULATORY COMMISSION (FERC):  The federal agency that, among
other functions, regulates all interstate natural gas pipelines and some
intrastate gas operations.

FUTURES CONTRACTS:  Contracts that obligate the seller to deliver and the buyer
to purchase a commodity at a fixed price at a specific date.

HEDGING:  The process of reducing financial exposure to adverse natural gas,
oil or other commodity price movements.

MUNICIPAL GAS SYSTEM:  A natural gas distribution system owned and operated by
one or more local governments.

OPERATOR (OF OIL AND GAS PROPERTIES):  The company responsible for exploration
and production activities for a specific project.

RATE STABILIZATION AND EQUALIZATION (RSE):  A rate-setting mechanism authorized
by the Alabama Public Service Commission which provides Alagasco, and some
other utilities in Alabama, with the opportunity to earn a return on average
equity within a designated range.

RESERVES, OIL AND GAS:  The amount of commercially recoverable oil or gas
estimated to exist within a given reservoir.

THROUGHPUT:  Total volumes of natural gas sold and transported.

TRANSPORTATION OR TRANSPORT:  Moving natural gas through company pipelines on a
contract basis for others.

UNITS OF MEASURE:

         Mcf     --       Thousand cubic feet
         MMcf    --       Million cubic feet
         Bcf     --       Billion cubic feet

(When an "e" follows these units of measure, the oil component has been
converted to its equivalent in cubic feet, with one barrel of oil equal to
6,000 cubic feet of gas.)

WORKING INTEREST:  The cost-bearing ownership interest under an oil and gas
lease.
