Energen hereby guarantees the performance by each of the other Participating
Employers of their respective obligations under the Plan. Neither the respective
benefit payment obligations of the Participating Employers nor Energen's
guarantee of performance is secured in any way. Such obligations and guarantee
constitute no more than unfunded and unsecured promises of payment and
performance. Each Participating Employer, other than Energen, shall reimburse
Energen for its allocable share of costs and expenses paid by Energen in
connection with the operation and administration of the Plan, and shall
reimburse Energen for any benefits paid by Energen under the Plan to
Participants to the extent allocable to such Participating Employer and its
Participants. Payments made to Participants by the Trust shall constitute
payments by Energen and Energen shall be reimbursed for such payments by the
appropriate Participating Employers.

         Section 2.3       Recordkeeping and Reporting. Each Participating
Employer, other than Energen, shall furnish to Energen the information with
respect to each of its Participants necessary to enable Energen to maintain
records sufficient to determine the benefits (and the compensation sources of
such benefits) which may become payable to or with respect to such Participants
and to give those Participants any reports which may be required under the terms
of the Plan or by law.

         Section 2.4       Termination of Participation. A Participating
Employer, other than Energen, may withdraw from participation in the Plan at any
time by providing Energen with 30 days advance written notice of such withdrawal
from participation and the effective date of such Participating Employer's
withdrawal, which 30-day notice period may be waived by Energen. In addition,
Energen may terminate a Participating Employer's participation in the Plan by
providing such Participating Employer with 30 days advance written notice, which
30-day notice period may be waived by the Participating Employer. A
Participating Employer which terminates its participation in the Plan shall
remain obligated under the Plan with respect to deferrals made prior to such
termination by its Participants (including subsequent investment performance
adjustments), unless otherwise expressly agreed by Energen with Energen fully
assuming such obligations.

         Section 2.5       Separate Accounting. Energen shall establish and
maintain separate Accounts for each of the Participating Employers and their
respective Participants. Such separate accounting is intended to comply with
Section 404(a)(5) of the Code and Section 1.404(a) - 12 of the Treasury
Regulations (which provide that an employer can deduct the amounts contributed
to a nonqualified plan in the taxable year in which an amount attributable to
the contribution is includable in the gross income of employees participating in
the plan, but, in the case of a plan in which more than one employee
participates only if separate accounts are maintained for each employee).

Committee may by express action designate other management level or highly
compensated employees of the Participating Employers as eligible to participate
in the Plan. If the Officers Review Committee designates a management level or
highly compensated employee as eligible to become a Participant in the Plan,
Energen shall inform the employee in writing of such designation and the date on
which the employee shall become a Participant in the Plan.

         Section 3.2       Participation. An individual eligible to participate
in the Plan shall become a Participant upon the filing with Energen of a
completed Deferral Election Form and acceptance of such form by Energen. The
name of each individual eligible to participate in the Plan and the date on
which such individual becomes a Participant in the Plan, shall be recorded on
Exhibit A, which exhibit is attached hereto and incorporated herein by reference
and which shall be revised by Energen from time to time to reflect the operation
of the Plan. Once an individual becomes a Participant in the Plan, the
individual shall remain a Participant until the benefits which may be payable to
the individual under the Plan have been distributed to or on behalf of the
individual.

         Section 3.3       Suspension of Eligibility. The Officers Review
Committee (or the Board of Directors if the affected Participant is a Director)
may in its discretion determine that a Participant will no longer be eligible to
participate in the Plan and in such event , the Participant's Section 4.1
compensation deferral election will immediately terminate and no additional
amounts shall be credited to his or her Accounts under Sections 7.1(a), (b), (c)
and 7.2(a) until such time as the individual is again determined to be eligible
to participate in the Plan by the Officers Review Committee (or Board of
Directors as appropriate) and makes a new Section 4.1 election. However, the
Account of such Participant shall continue to be adjusted by the other
provisions of Sections 7.1 and 7.2 until fully distributed.

         Section 4.1       Deferred Compensation. A Participant may elect to
defer receipt of part or all of any one or more items of Cash Compensation
and/or Stock Compensation. A Participant may defer an item of compensation only
to the extent that the Participant is entitled to receive such item of
compensation. Upon such deferral, the Participant will have no further right to
such deferred compensation other than as provided under the Plan. Such deferred
compensation shall be the record of the value of such deferred compensation
credited to a Participant's Account and shall be used solely for accounting
purposes.

         Section 4.2       Form and Effectiveness of Deferral Election.
Elections to defer compensation under the Plan shall be made in writing on the
Deferral Election Form. Such elections may be revised or terminated by the
making of a new deferral election on the Deferral Election Form. Deferral
elections (including revisions or terminations of prior elections) shall be
effective for Qualifying Compensation (subject to the last sentence of this
section). Notwithstanding the other provisions of this Plan, a Participant's
Deferral Election Form and the various elections and selections made thereon
(excepting elections to terminate deferral of one or more items of
compensation), shall not become effective unless acceptance thereof by Energen
in its sole discretion is acknowledged in writing. A Participant's election to
terminate a prior compensation deferral election shall be effective upon
delivery to Energen and shall be accepted and honored by the Participating
Employers with respect to Qualifying Compensation (subject to the following
sentence). An election to reduce or terminate a prior election to defer an item
of compensation shall in no event be effective with respect to compensation for
services rendered during a period of service commencing prior to the date of
such election.

         Section 4.3       Participant Accounts. A Company Stock Account and an
Investment Account shall be established and maintained for each Participant. The
Company Stock Account shall be measured in shares of Common Stock and the
Investment Account shall be measured in dollars. The Company Stock Account shall
be credited as described in Section 7.1 for deferred amounts attributable to (i)
Stock Compensation and (ii) such amounts of Cash Compensation as may be
allocated to the Company Stock Account pursuant to Section 7.1(g). The
Investment Account shall be credited as described in Section 7.2 for any
deferred amounts of Cash Compensation which are not allocated to the Company
Stock Account pursuant to Section 7.1(g).

         Section 4.4       Discretionary Amounts. In addition to amounts
deferred by a Participant, the Board of Directors may from time to time, in its
sole discretion, authorize a Participant's Participating Employer to credit the
Participant's Company Stock Account with additional amounts (denominated in
dollars). Such additional amounts may be authorized for such purpose or purposes
as the Board of Directors may deem appropriate, including, without limitation,
as mirror employer matching contributions or ESOP contributions made by such
Participating Employer with respect to The Energen Corporation Employee Savings
Plan.

         Section 5.2       Limitation on Benefits. The benefits that may be

                                 DISTRIBUTIONS

         Section 6.1       Distributable Events. A Participant's Distributable
Event shall be the first to occur of the following events; provided, that events
(b) - (e) shall be Distributable Events only if so elected by the Participant in
the Deferral Election Form and further provided that events (d) - (f) are
subject to Section 6.6:

                  (a)    the Participant's 70th birthday (i.e., the 70th
                         anniversary of the Participant's birth) or such earlier
                         birthday as the Participant may specify in the Deferral
                         Election Form;

                  (b)    Disability (as defined in Section 1.1);

                  (c)    the Participant's death;

                  (d)    the first date on which the Participant is NEITHER an
                         employee nor a Director of any Participating Employer;

                  (e)    such other event as the Participant may specify in the
                         Deferral Election Form (subject to approval of
                         Energen);

                  (f)    the taking of action by the Board of Directors to
                         terminate the Plan pursuant to Section 14.1, or

                  (g)    termination for Cause subject to and in accordance with
                         Section 6.7.

         A Participant's Distributable Event elections must be made on the
Participant's initial Deferral Election Form and are irrevocable; provided, that
Energen may in its sole discretion allow a Participant to make different
Distributable Event elections applicable only with respect to Qualifying
Compensation for services rendered during periods of service commencing after
the date of such election.

         Section 6.2       Distribution of Benefits.

                  (a)      Distribution Commencement Date. Excepting withdrawals
under Sections 6.3 and 6.4 which shall be distributed in accordance with those
Sections, distribution of a Participant's Plan benefit shall commence as of the
first day of the second calendar month immediately following the calendar month
in which the Participant's applicable Distributable Event occurs.

                  (b)      Form of Distribution. Benefits attributable to the
value of the Investment Account shall be delivered to the Participant in
dollars. Benefits attributable to the Company Stock Account shall be delivered
to the Participant in the form of shares of Common Stock. To the extent that the
distribution is in the form of shares of Common Stock, such delivery shall be
subject to all applicable securities laws and regulations and Energen shall have
taken all steps, if any, including registration and listing, as may be necessary
to make the shares immediately saleable by the Participant without further
regulatory action or compliance on the part of the Participant (other than



                                       10
<PAGE>   11
compliance with paragraphs (f) and (h) of Rule 144 under the Securities Act of
1933). The Participant shall reasonably cooperate with Energen, at Energen's
expense, to facilitate such compliance and related actions by Energen.

                  (c)      Payment Options. In the event a Participant becomes
eligible to receive a payment of benefits under the Plan, the benefits payable
to the Participant or, in the event of the Participant's death, to the
Participant's designated beneficiary under the Plan shall be paid in accordance
with one of the payment options available under the Plan as elected by the
Participant on the Participant's Deferral Election Form. The Participant may
elect separate payment options with respect to the Investment Account and the
Company Stock Account. A Participant may change payment options by electing
another payment option available under the Plan on a subsequent Deferral
Election Form, but such change in payment option will not be effective until the
calendar year following the calendar year in which the change was elected.
Further, in no event will any such change in payment option be effective if such
change is elected during the calendar year in which the Distributable Event
occurs and no further elections may be made once a Distributable Event occurs.
The payment options include installment payments over a period certain, a lump
sum payment, and such other payment method as may be specified by the
Participant and accepted by Energen. The Board of Directors may, in its sole
discretion, reduce the payment period over which payments would have been made
pursuant to the payment option elected by a Participant (including consolidation
into a lump sum); provided, that in the event of a Change in Control, no
reduction of a payment period may be made prior to the fifth anniversary of such
Change in Control. Absent a payment option election, the Board of Directors
shall direct the payment of any benefits payable under the Plan to or on behalf
of the Participant in a lump sum payment to the Participant, or in the event of
the Participant's death, to the Participant's designated beneficiary under the
Plan.

         Section 6.3       Early Withdrawals. Notwithstanding any provision in
this Plan to the contrary, a Participant may request, by providing a written
request to the Officers Review Committee, a withdrawal prior to the distribution
date under the Plan of all or any portion of his or her benefits from any of his
or her Accounts under the Plan in increments of 25% (of aggregate Account
value). If such a request is approved by the Officers Review Committee, which
decision by the Officers Review Committee shall be made in its sole discretion
on a case by case basis, a distribution of such benefits may be made to the
Participant subject to a penalty for such an early withdrawal at any point equal
to a six-month period of nonparticipation (during which no additional amounts
will be credited to the Participant's Accounts under Sections 7.1(a), (b), (c)
and 7.2(a) of the Plan) for each 25% increment withdrawn. The nonparticipation
period would begin as of the date on which the request made by the Participant
is approved by the Officers Review Committee. As a result, a Participant
withdrawing his or her entire benefit from all of his or her Accounts would be
excluded from eligibility to participate in the Plan for a 24-month period
beginning as of the date of such approval by the Officers Review Committee. In
addition, a penalty of 10% of the amount withdrawn will be imposed on any
withdrawal made pursuant to this Section 6.3.

         Section 6.4       Hardship Withdrawals. In addition to the other
distribution and withdrawal provisions of this Article VI and notwithstanding
any provision herein to the contrary, in the event a Participant incurs an
unforeseeable emergency, the Participant may request, by providing a written
request to the Officers Review Committee, a hardship withdrawal of all or any
portion of his or her




                                       11
<PAGE>   12

benefits from his or her Accounts under the Plan. An unforeseeable emergency is
a severe financial hardship to the Participant resulting from a sudden and
unexpected illness or accident of the Participant or of a dependent (as defined
in Section 152(a) of the Code) of the Participant, loss of the Participant's
property due to casualty, or other similar extraordinary and unforeseeable
circumstances arising as a result of events beyond the control of the
Participant. If such a request is approved by the Officers Review Committee,
which decision by the Officers Review Committee shall be made in its sole
discretion on a case by case basis, a hardship withdrawal may be permitted under
this Section 6.4. Withdrawals of amounts because of an unforeseeable emergency
are only permitted to the extent reasonably needed to satisfy the emergency
need. This provision shall be interpreted in a manner not inconsistent with
Sections 1.457-2(h)(4) and 1.457-2(h)(5) of the Treasury Regulations.

         Section 6.5       Distributions as Result of Tax Determination.
Notwithstanding any provision in this Plan to the contrary, if, at any time, a
court or the Internal Revenue Service determines that any amounts or shares
credited to a Participant's Accounts under the Plan or Trust are includable in
the gross income of the Participant and subject to tax, the Officers Review
Committee may, in its sole discretion, permit a lump sum distribution of an
amount equal to the amounts or shares determined to be includable in the
Participant's gross income.

         Section 6.6       No Parachute Payment. An event described in Sections
6.1(d), (e) and (f) shall not constitute a Distributable Event if the Officers
Review Committee in its reasonable discretion following consultation with
appropriate tax and/or legal advisors reasonably determines that such
distribution will likely constitute a parachute payment for purposes of Section
280G of the Code. Furthermore, if such event occurs subsequent to a Change in
Control, the Officers Review Committee shall, at Energen's expense, promptly
request a written opinion of the Independent Auditor with respect to the
applicability of such Section 280G and such event shall not constitute a
Distributable Event unless and until the Independent Auditor delivers its
written unqualified opinion, a copy of which shall be provided to the
Participant, to the effect that a distribution of benefits as a result of such
event will not constitute a parachute payment under Section 280G of the Code. As
used in this Section 6.6, the term independent auditor means the firm of
certified public accountants which at the time of the Change in Control had been
most recently engaged by Energen or such other comparable and nationally
recognized firm of certified public accountants as may be selected by the
Officers Review Committee in its reasonable discretion.

         Section 6.7       Distribution Upon Termination for Cause. In the event
that a Participant is terminated for Cause (as defined below), the Company may,
at its discretion, treat such termination or any date subsequent thereto as a
Distributable Event. For purposes of this Plan, termination for Cause means
termination based on any of the following:

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



                                       12
<PAGE>   13

                           (ii)     the engaging by Participant in willful
                           misconduct which is demonstrably injurious to any one
                           or more of the Participating Employers monetarily or
                           otherwise; or

                           (iii)    the conviction of Participant of a felony.


                                  ARTICLE VII.
                             VALUATION OF BENEFITS.

         Section 7.1       Company Stock Account.

                  (a)      Stock Award Deferral. When a Participant's Company
Stock Account is to be credited for deferred amounts attributable to awards
which would otherwise have been distributed to the Participant in the form of
Common Stock, then the number of shares of Common Stock which would have
otherwise been distributed to the Participant shall be credited to the
Participant's Company Stock Account as of the date that such distribution to the
Participant would have otherwise occurred.

                  (b)      Cash Deferral. When a Participant's Company Stock
Account is to be credited for deferred amounts which would have otherwise been
distributed to the Participant in the form of cash, then the Participant's
Company Stock Account shall be credited with that number of shares of Common
Stock equal to the number of such shares that could have been purchased with
such cash amounts at the Fair Market Value Average for the last business day of
the month during which such cash amounts would have otherwise been distributed
to the Participant.

                  (c)      Discretionary Amount. When a participant's Company
Stock Account is to be credited for a Discretionary Amount, it shall be credited
with that number of shares of Common Stock equal to the number of such shares
(including fractional shares) that could have been purchased with the dollar
amount of the Discretionary Amount at the Fair Market Value Average for the last
business day of the month during which such Discretionary Amount is authorized
or such other date as may be specified in the Discretionary Amount
authorization.

                  (d)      Dividends. A Participant's Company Stock Account
                           shall be credited on each Common Stock dividend
                           payment date with that number of shares which could
                           have been acquired through the Energen Corporation
                           Dividend Reinvestment and Direct Stock Purchase Plan
                           or similar successor plan (the "DRIP") by the
                           reinvestment of the dividends payable on the number
                           of shares of Common Stock credited to such Company
                           Stock Account as of the record date for such
                           dividend. In the event that the DRIP is no longer
                           operative, or at such time as the Officers Review
                           Committee in its discretion shall specify, the number
                           of dividend reinvestment shares shall be calculated
                           based on the Fair Market Value Average for the
                           dividend payment date.

                  (e)      Stock Dividend, etc. The Company Stock Account shall
be adjusted to reflect any change in the outstanding Common Stock by reason of
any stock dividend or split,




                                       13
<PAGE>   14

recapitalization, merger, consolidation, combination, Change in Control,
exchange of shares, exchange for cash or other consideration, or other similar
corporate change.

                  (f)      Transfer upon Change in Control. In the event of a
Change in Control, effective as of the close of business on the date of the
Change in Control, each Participant's Investment Account shall be credited with
an amount measured in dollars equal to the value of such Participant's Company
Stock Account as of such time. Upon such crediting of the Investment Account,
the Participant's Company Stock Account shall be closed and the Participant
shall have no further interest in the Company Stock Account.

                  (g)      Allocation of Cash Compensation. A Participant may
request that part or all of deferred compensation attributable to Cash
Compensation be allocated to the Participant's Company Stock Account. A
Participant's request to make such an allocation or change a previous allocation
must be in writing on an Allocation Request Form. All such requests are subject
to acceptance by Energen in its discretion. If accepted by Energen, the
allocation request will be effective as of the date specified by the request.


         Section 7.2       Investment Account.

                  (a)      Deferred Amounts. When a Participant's Investment
Account is to be credited with a deferred amount, that amount measured in
dollars equal to such deferred amount shall be credited to the Investment
Account as of the close of business on the date that such amount would have
otherwise been paid to the Participant.

                  (b)      Interest. Subject to 7.2(c), as of the close of the
                           last day of each calendar quarter, an additional
                           amount shall be credited to each Participant's
                           Investment Account equal to the product of (i) the
                           average daily balance in such Investment Account for
                           the quarter, times (ii) one-fourth of the annual
                           prime rate for corporate borrowers quoted at the
                           beginning of the quarter by AmSouth Bank of Alabama,
                           Birmingham, Alabama (or such other comparable
                           interest rate as the Officers Review Committee may
                           designate from time to time).

                  (c)      Investment Options. Energen may permit a Participant
to allocate the Participant's Investment Account among one or more investment
options for purposes of measuring the value of the benefit. To the extent that
the Investment Account is allocated to an investment option, it shall not be
credited with interest under Section 7.2(b). That portion of the Investment
Account allocated to an investment option shall be deemed to be invested in such
investment option and shall be valued as if so invested, reflecting all
earnings, losses and other distributions or charges and changes in value which
would have been incurred through such an investment. The determination of which
investment options, if any, to make available, and the continued availability of
selected investment options rests in Energen's sole discretion; provided, that
subsequent to a Change in Control, Energen shall maintain the availability of
those investment options in place at the time of the Change in Control (or
substantially equivalent investment options).



                                       14
<PAGE>   15

                  (d)      Participant Allocation Request. A Participant's
request to allocate or reallocate among investment options must be in writing on
an Allocation Request Form in such increments as Energen may require. All such
requests are subject to acceptance by Energen at its discretion. If accepted by
Energen, an allocation request will be effective as of the close of business on
the allocation date (as defined in Section 7.4).

         Section 7.3       Hypothetical Accounts. The Accounts established under
this Plan shall be hypothetical in nature and shall be maintained for
bookkeeping purposes only. Neither the Plan nor any of the Accounts (or
subaccounts) shall hold or be required to hold any actual funds or assets.

         Section 7.4       Allocation Date. Upon acceptance of an allocation
request pursuant to Section 7.1(g) or 7.2(d), Energen will process the request
as soon as reasonably administratively practicable and the request shall be
implemented and reflected in the Participant's account as of the close of
business on such date as may be determined by Energen in its reasonable
discretion (the "allocation date").

                                  ARTICLE VIII.
                               NONTRANSFERABILITY

         Section 8.1       Anti-Alienation of Benefits. Any benefits which may
be credited to a Participant's Accounts under the Plan, and any rights or
privileges pertaining thereto, may not be anticipated, alienated, sold,
transferred, assigned, pledged, encumbered, or subjected to any charge or legal
process; and no interest or right to receive a benefit may be taken, either
voluntarily or involuntarily, for the satisfaction of the debts of, or other
obligations or claims against, such person or entity, including claims for
alimony, support, separate maintenance and claims in bankruptcy proceedings.

         Section 8.2       Incompetent Participants. If any person who may be
eligible to receive a payment under the Plan has been legally declared
incompetent and a conservator or other person legally charged with the care of
such person or of his or her estate has been appointed, any payment under the
Plan to which the person is eligible to receive shall be paid to such
conservator or other person legally charged with the care of the person or his
or her estate. Any such payment shall be a payment for the account of such
person and a complete discharge of any liability of the Participating Employers
and the Plan therefor.

         Section 8.3       Designated Beneficiary. In the event of a
Participant's death prior to the payment of all or a portion of any benefits
which may be payable with respect to the Participant under the Plan, the payment
of any benefits payable on behalf of the Participant under the Plan shall be
made to the Participant's beneficiary designated on a Deferral Election Form. If
no such beneficiary has been designated, payment shall be made as required under
the Participant's will; or, in the event that there shall be no functioning will
under applicable state law, then to such persons as, at the date of the
Participant's death, would be entitled to share in the distribution of such
deceased Participant's personal estate under the provisions of the applicable
statute then in force governing the decedent's intestate property, in the
proportions specified in such statute.

entitled to any voting rights with respect to any shares credited to his or her
Company Stock Account.


                                   ARTICLE XI.
                            ADMINISTRATION OF A PLAN

         Section 11.1      Administrator. The administrator of the Plan shall be
Energen. However, the Board of Directors shall act on behalf of Energen with
respect to the administration of the Plan and may delegate authority with
respect to the administration of the Plan to the Officers Review Committee or
such other committee, person or persons as it deems necessary or appropriate for
the administration and operation of the Plan.

         Section 11.2      Authority of Administrator. Energen shall have the
authority, duty and power to interpret and construe the provisions of the Plan
as it deems appropriate, to adopt, establish and revise rules, procedures and
regulations relating to the Plan, to determine the conditions subject to which
any benefits may be payable, to resolve all questions concerning the status and
rights of Participants and others under the Plan, including, but not limited to,
eligibility for benefits and to make any other determinations which it believes
necessary or advisable for the administration of the Plan. Energen shall have
the duty and responsibility of maintaining records, making the requisite
calculations and disbursing payments hereunder. The determinations,
interpretations, regulations and calculations of Energen shall be final and
binding on all persons and parties concerned. The Secretary of Energen shall be
the agent of the Plan for the service of legal process in accordance with
Section 502 of the Employee Retirement Income Security Act of 1974, as amended.


         Section 11.3      Operation of Plan and Claims Procedures. Energen
shall be responsible for the general operation and administration of the Plan
and for carrying out the provisions thereof. Energen shall be responsible for
the expenses incurred in the administration of the Plan. Energen shall also be
responsible for determining eligibility for payments and the amounts payable
pursuant to the Plan. Energen shall be entitled to rely conclusively upon all
tables, valuations, certificates, opinions and reports furnished by any actuary,
accountant, controller, counsel or other person employed or engaged by Energen
with respect to the Plan. The procedures for filing claims for payments under
the Plan are described below. For claims procedures purposes, the "Claims





                                       16
<PAGE>   17

Manager" shall be Energen.

                  (a)      Claim Forms. It is the intent of Energen to make
payments under the Plan without the Participant having to complete or submit any
claims forms. However, a Participant who believes he or she is entitled to a
payment under the Plan may submit a claim for payments in writing to Energen.
Any claim for payments under the Plan must be made by the Participant or his or
her beneficiary in writing and state the claimant's name and the nature of
benefits payable under the Plan on a form acceptable to Energen. If for any
reason a claim for payments under the Plan is denied by Energen, the Claims
Manager shall deliver to the claimant a written explanation setting forth the
specific reasons for the denial, specific references to the pertinent provisions
of the Plan on which the denial is based, a description of any additional
material or information necessary for the claimant to perfect the claim and an
explanation of why such material or information is necessary, and information on
the procedures to be followed by the claimant in obtaining a review of his or
her claim, all written in a manner calculated to be understood by the claimant.
For this purpose:

                           (i)      The claimant's claim shall be deemed to be
                           filed when presented orally or in writing to the
                           Claims Manager.

                           (ii)     The Claims Manager's explanation shall be in
                           writing delivered to the claimant within 90 days of
                           the date the claim is filed.

                  (b)      Review. The claimant shall have 60 days following his
or her receipt of the denial of the claim to file with the Claims Manager a
written request for review of the denial. For such review, the claimant or the
claimant's representative may review pertinent documents and submit written
issues and comments.

                  (c)      Decision on Review. The Claims Manager shall decide
                           the issue on review and furnish the claimant with a
                           copy within 60 days of receipt of the claimant's
                           request for review of the claimant's claim. The
                           decision on review shall be in writing and shall
                           include specific reasons for the decision, written in
                           a manner calculated to be understood by the claimant,
                           as well as specific references to the pertinent
                           provisions in the Plan on which the decision is
                           based. If a copy of the decision is not so furnished
                           to the claimant within such 60 days, the claim shall
                           be deemed denied on review. In no event may a
                           claimant commence legal action for benefits the
                           claimant believes are due the claimant until the
                           claimant has exhausted all of the remedies and
                           procedures afforded the claimant by this Section
                           11.3.

         Section 11.4      Participant's Address. Each Participant shall keep
Energen informed of his or her current address and the current address of his or
her beneficiary. Energen shall not be obligated to search for any person. If the
location of a Participant is not made known to Energen within three (3) years
after the date on which payment of the Participant's benefits payable under the
Plan may be made, payment may be made as though the Participant had died at the
end of the three-year period. If, within one (1) additional year after such
three-year period has elapsed, or, within three (3) years after the actual death
of a Participant, Energen is unable to locate any designated




                                       17

beneficiary of the Participant, then Energen shall have no further obligation to
pay any benefit hereunder to or on behalf of such Participant or designated
beneficiary and such benefits shall be irrevocably forfeited.


                                  ARTICLE XII.
                            MISCELLANEOUS PROVISIONS

         Section 12.1      No Employment Rights. Neither the Plan nor any action
taken hereunder shall be construed as giving any Participant any right to be
retained in the service or employ of any Participating Employer.

         Section 12.2      Participants Should Consult Advisors. Neither any
Participating Employer, nor their respective directors, officers, employees or
agents makes any representation or warranty with respect to the state, federal
or other tax, financial, estate planning, or the securities or other legal
implications of participation in the Plan. Participants should consult with
their own tax, financial and legal advisors with respect to their participation
in the Plan.

         Section 12.3      Unfunded and Unsecured. The Plan shall at all times
be considered entirely unfunded both for tax purposes and for purposes of Title
I of the Employee Retirement Income Security Act of 1974, as amended, and no
provision shall at any time be made with respect to segregating assets of any
Participating Employer for payment of any amounts hereunder. Any funds invested
hereunder allocable to a Participating Employer shall continue for all purposes
to be part of the respective general assets of such Participating Employer and
available to the general creditors of such Participating Employer in the event
of a bankruptcy (involvement in a pending proceeding under the Federal
Bankruptcy Code) or insolvency (inability to pay debts as they mature) of such
Participating Employer. Energen shall promptly notify the Trustee and the
applicable Participants of such bankruptcy or insolvency of a Participating
Employer. No Participant or any other person shall have any interests in any
particular assets of any Participating Employer by reason of the right to
receive a benefit under the Plan and to the extent the Participant or any other
person acquires a right to receive benefits under the Plan, such right shall be
no greater than the right of any general unsecured creditor of any Participating
Employer. The Plan constitutes a mere promise by the Participating Employers to
make payments to the Participants in the future. With respect to the guarantee
of Energen under Section 2.2, Participants have rights only as general unsecured
creditors of Energen. Nothing contained in the Plan shall constitute a guaranty
by any Participating Employer or any other person or entity that any funds in
any trust or the assets of any Participating Employer will be sufficient to pay
any benefit hereunder. Furthermore, no Participant shall have any right to a
benefit under the Plan except in accordance with the terms of the Plan.

         Section 12.4      The Trust.

                  (a)      Establishment of Trust. In order to provide assets
from which to fulfill its obligations to the Participants and their
beneficiaries under the Plan, Energen shall establish a Trust by a trust
agreement with a third party, the Trustee, to which Energen may, in its
discretion, contribute cash or other property, including securities issued by
Energen, to provide for the benefit




                                       18
<PAGE>   19

payments under the Plan. The Trustee will have the duty to invest the Trust
assets and funds in accordance with the terms of the Trust. Energen shall be
entitled at any time, and from time to time, in its sole discretion, to
substitute assets of at least equal fair market value for any assets held in the
Trust. All rights associated with the assets of the Trust will be exercised by
the Trustee or the person designated by the Trustee, and will in no event be
exercisable by or rest with Participants or their beneficiaries. The Trust shall
provide that in the event of the insolvency of Energen, the Trustee shall hold
the assets for the benefit of the general creditors of Energen and its
affiliated companies. The Trust shall be based on the model trust contained in
Internal Revenue Service Revenue Procedure 92-64 with such changes and
modifications as may be approved by Energen.

                  (b)      Contribution Upon Change in Control. If as of the
close of business on the date of a Change in Control, the aggregate value of the
Participant Accounts exceeds the value of the Trust assets, then within thirty
days of such Change in Control, Energen shall contribute to the Trust assets
having a value at least equal to the amount of such excess.

         Section 12.5      Plan Provisions. Except when otherwise required by
the context, any singular terminology shall include the plural.

         Section 12.6      Severability. If a provision of the Plan shall be
held to be illegal or invalid, the illegality or invalidity shall not affect the
remaining parts of the Plan and the Plan shall be construed and enforced as if
the illegal or invalid provision had not been included.

         Section 12.7      Applicable Law. To the extent not preempted by the
laws of the United States, the laws of the State of Alabama shall apply with
respect to the Plan.


                                  ARTICLE XIII.
                                   AMENDMENTS

         Section 13.1      Amendment of the Plan. Energen reserves the power to
alter, amend or wholly revise the Plan at any time and from time to time by the
action of the Board of Directors and the interest of each Participant is subject
to the powers so reserved; provided, however, that no amendment made subsequent
to a Change in Control shall be effective to the extent that it would have a
materially adverse impact on a Participant's reasonably expected economic
benefit attributable to compensation deferred by the Participant prior to the
Change in Control. An amendment shall be authorized by the Board of Directors
and shall be stated in an instrument in writing signed in the name of Energen by
a person or persons authorized by the Board of Directors. After the instrument
has been so executed, the Plan shall be deemed to have been amended in the
manner therein set forth, and all parties interested herein shall be bound
thereby. No amendment to the Plan may alter, impair, or reduce the benefits
credited to any Accounts prior to the effective date of such amendment without
the written consent of any affected Participant.

                                  ARTICLE XIV.
                                  TERM OF PLAN

         Section 14.1      Term of the Plan. Energen may at any time terminate
the Plan by action of the Board of Directors with such termination being
effective as of the date that all Participant Accounts have been distributed to
Participants in accordance with and subject to the provisions of Article VI of
the Plan including, without limitation, Section 6.6 of the Plan. Effective as of
the date of such Board of Directors action (or such later date as may be
specified therein) all Section 4.1 compensation deferral elections will
terminate and no further amounts shall be credited to any Accounts of any
Participant under Sections 7.1(a), (b), (c) and 7.2(a) after such date. However,
the Participants' Accounts shall continue to be adjusted by the other provisions
of Sections 7.1 and 7.2 until all benefits are distributed to the Participants
or to the Participants' beneficiaries.
