Participant has not substantially performed such Participant’s duties. 
 (2) The engaging by a Participant in willful,
reckless or grossly negligent misconduct which is demonstrably injurious to Energen or a Subsidiary monetarily or otherwise; or 
 (3) The conviction of a Participant of a felony. 
 (e) “Change in Control” means: the occurrence of any one

stock of Energen (the “Outstanding Common Stock”) or (ii) the combined voting power of the then outstanding voting securities of Energen entitled to vote generally in the election of directors (the “Outstanding Voting
Securities”); provided, however, that for purposes of this subsection (1) any acquisition by an employee benefit plan (or related trust) sponsored or maintained by Energen or any corporation controlled by Energen shall not constitute a

Energen’s shareholders, was approved by a vote of at least a majority of the directors then comprising the Incumbent Board shall be considered as though such individual were a member of the Incumbent Board, but excluding, for this purpose, any

 2. Share
Limitations. 
 2.1 Shares Subject to the Plan. Subject to adjustment in accordance with Section 3, as of
January 1, 2007, 3,539,608 shares of Stock remained reserved and available for issuance under the Plan for outstanding and future Awards, reflecting the original 650,000-share authorization, the 1998 stock split adjustment, an additional
1,500,000 shares authorized at the January 2002 shareholder meeting, and the 2005 stock split adjustment). Shares of Stock allocable to an Award or portion of an Award that is canceled by forfeiture, expiration or for any other reason (excepting
pursuant to a stock appreciation right election under Section 6.2(i)) shall again be available for additional Awards. If any option granted under the Plan shall be canceled as to any shares of Stock pursuant to Section 6.2(i) (stock
appreciation rights), then such shares of Stock shall not be available for the grant of another Award. 
 2.2 Individual
Limitation. Subject to adjustment in accordance with Section 3, the maximum aggregate number of shares of Stock represented by all Awards granted to any one Participant during any one Energen fiscal year shall not exceed 400,000 (reflects
the 2005 stock split adjustment), calculated assuming maximum payout of the Awards and with each Performance Share representing one share of Stock. 
 3. Adjustments in Event of Change in Common Stock. In the event of any change in the Stock by reason of any stock dividend, recapitalization, reorganization, merger, consolidation, split-up,
combination or exchange of shares, or rights offering to purchase Stock at a price substantially below fair market value, or of any similar change affecting the Stock, the number and kind of shares which thereafter may be available for issuance
under the Plan, the terms of outstanding Awards shall be appropriately adjusted consistent with such change in such manner as

  

 5 









 
the Committee may deem equitable to prevent dilution or enlargement of the rights granted to, or available for, Participants in the Plan. If the adjustment would result in fractional shares with
respect to an Award, then the Committee may make such further adjustment (including, without limitation, the use of consideration other than Stock or rounding to the nearest whole number of shares) as the Committee shall deem appropriate to avoid
the issuance of fractional shares. 
 4. Administration of the Plan. The Plan shall be administered by the Committee. No
member of the Committee shall be eligible to participate in the Plan while serving as a member of the Committee. Subject to the provisions of the Plan, the Committee shall have the exclusive authority to select the Employees who are to be
Participants in the Plan, to determine the Award to be made to each Participant, and to determine the conditions subject to which Awards will become payable under the Plan. The Committee shall have full power to administer and interpret the Plan and
to adopt such rules and regulations consistent with the terms of the Plan as the Committee deems necessary or advisable in order to carry out the provisions of the Plan. The Committee’s interpretation and construction of the Plan and of any
conditions applicable to Awards shall be conclusive and binding on all persons, including Energen and all Participants. Any action which can be taken, or authority which can be exercised, by the Committee with respect to the Plan, may also be taken
or authorized by the Board. 
 5. Participation. Participants in the Plan shall be selected by the Committee from those
Employees who, in the judgment of the Committee, have significantly contributed or can be expected to significantly contribute to Energen’s success. 
 6. Options 
 6.1 Grant of Options. Subject to the provisions of the
Plan, the Committee may (a) determine and designate from time to time those Participants to whom options are to be granted and the number of shares of Stock to be optioned to each employee; (b) authorize the granting of Incentive Stock
Options, Nonqualified Stock Options, or combination of Incentive Stock Options and Nonqualified Stock Options; (c) determine the number of shares subject to each option; (d) determine the time or times when each Option shall become
exercisable and the duration of the exercise period; and (e) determine whether and, if applicable, the manner in which each option shall contain stock appreciation rights and/or dividend equivalents; provided, however, that (i) no
Incentive Stock Option shall be granted after the expiration of ten years from the effective date of the Plan specified in Section 15 and (ii) the aggregate Fair Market Value (determined as of the date the option is granted) of the Stock
with respect to which Incentive Stock Options are exercisable for the first time by any employee during any calendar year (under all plans of Energen and its Subsidiaries) shall not exceed $100,000. 
 6.2 Terms and Conditions of Options. Each option granted under the Plan shall be evidenced by a written agreement. Such agreement
shall be subject to the following express terms and conditions and to such other terms and conditions as the Committee may deem appropriate: 
 (a) Option Period. Each option agreement shall specify the period for which the option thereunder is granted and shall provide that the option shall expire at the end of such period. The Committee
may extend such period provided that, in the case of an Incentive Stock Option, such extensions shall not in any way disqualify the option as an Incentive Stock Option. In no case shall such period for an Incentive Stock Option, including any such
extensions, exceed ten years from the date of grant, provided, however that, in the case of an Incentive Stock Option granted to a Ten Percent Stockholder, such period, including extensions, shall not exceed five years from the date of grant.

  

 6 









 (b) Option Price. The option price per share shall be determined by the Committee at
the time any option is granted, and shall be not less than (i) the Fair Market Value, or (ii) in the case of an Incentive Stock Option granted to a Ten Percent Stockholder, 110 percent of the Fair Market Value, (but in no event less than
the par value) of one share of Stock on the date the option is granted, as determined by the Committee. 
 (c) Exercise of
Option. No part of any option may be exercised until the optionee shall have remained in the employ of Energen or of a Subsidiary for such period, if any, as the Committee may specify in the option agreement, and the option agreement may provide
for exercisability in installments. The Committee shall have full authority to accelerate for any reason it deems appropriate the vesting schedule of all or any part of any option issued under the Plan. Each option shall be exercisable in whole or
part on such date or dates and during such period and for such number of shares as shall be set forth in the applicable option agreement. An optionee electing to exercise an option shall give written notice to Energen of such election and of the
number of shares the optionee has elected to purchase and shall at the time of exercise tender the full purchase price of the shares the optionee has elected to purchase plus any required withholding taxes in accordance with Sections 6.2(d) and 9.

 (d) Payment of Purchase Price upon Exercise. The purchase price of the shares as to which an option shall be exercised
shall be paid to Energen at the time of exercise (i) in cash, (ii) in Stock already owned by the optionee having a total Fair Market Value equal to the purchase price and not subject to any lien, encumbrance or restriction on transfer
other than pursuant to federal or state securities laws, (iii) by election to have Energen withhold (from the Stock to be delivered to the optionee upon such exercise) shares of Stock having a Fair Market Value equal to the purchase price or
(iv) by any combination of such consideration having a total Fair Market Value equal to the purchase price; provided that the use of consideration described in clauses (ii), (iii) and (iv) shall be subject to approval by the
Committee. In addition the Committee in its discretion may accept such other consideration or combination of consideration as the Committee shall deem to be appropriate and to have a total Fair Market Value equal to the purchase price. In each case,
Fair Market Value shall be determined as of the Exercise Date. 
 (e) Exercise in the Event of Death or Termination of
Employment. If an optionee’s employment by Energen and all Subsidiaries shall terminate for Cause, then all options held by the terminated Employee shall immediately expire. In the event of a Qualified Termination, then all options (subject
to the pre-Change in Control grant date limitation of Section 1(w)(5)), held by the optionee shall be immediately and fully vested and, subject to the following sentence, may be exercised on or prior to the applicable Expiration Dates. With respect
to options issued on or after October 25, 2006, (i) in the event of a Section 1(w)(4) Qualified Termination due to retirement, the

  

 7 









 
options may be exercised on or prior to the earlier of the applicable Expiration Dates or the fifth anniversary of the termination date; and (ii) in the event of any other Qualified
Termination, the options may be exercised on or prior to the earlier of the applicable Expiration Dates or the third anniversary of the termination date. If an optionee’s employment by Energen and all Subsidiaries shall terminate for any reason
other than Cause or a Qualified Termination, then all of the optionee’s unvested options shall expire as of the termination date and all of the optionee’s vested options shall expire ninety days following the date of termination of
employment, provided that the Committee shall have the authority to extend such option expiration date up to the original Expiration Date. Without limiting the generality of Section 5(c), the Committee shall have full authority to accelerate
the vesting schedule of all or any part of any option issued under the Plan and held by an employee who has terminated or plans to terminate his or her employment, such that a terminated employee, his heirs or personal representatives may exercise
(at such time or times on or prior to the applicable Expiration Dates as may be specified by the Committee) any part or all of any unvested option under the Plan held by such employee at the date of his or her termination of employment. The
foregoing notwithstanding, the Committee may at the time of grant provide for different or supplemental terms and conditions with respect to termination of employment and any such terms and conditions expressly provided in the written option
agreement shall be controlling with respect to that option. 
 (f) Nontransferability. Except as may otherwise be
provided in this Section 5(f), no option granted under the Plan shall be transferable other than by will or by the laws of descent and distribution and, during the lifetime of the optionee, an option shall be exercisable only by the optionee.
The foregoing notwithstanding, the optionee may transfer Nonqualified Stock Options to (i) the optionee’s spouse or natural, adopted or step-children or grandchildren (including the optionee, “Immediate Family Members”),
(ii) a trust for the benefit of one or more of the Immediate Family Members, (iii) a family charitable trust established by one or more of the Immediate Family Members, or (iv) a partnership in which the only partners are (and, except
as may be otherwise agreed by the Committee, will remain during the option period) one or more of the Immediate Family Members. Any options so transferred shall not be further transferable except in accordance with the terms of this Plan, shall
remain subject to all terms and conditions of the Plan and the applicable option agreement, and may be exercised by the transferee only to the extent that the optionee would have been entitled to exercise the option had the option not been
transferred. 
 (g) Investment Representation. To the extent reasonably necessary to assure compliance with all
applicable securities laws, upon demand by the Committee for such a representation, the optionee shall deliver to the Committee at the time of any exercise of an option or portion thereof or settlement of stock appreciation rights or dividend
equivalents a written representation that the shares to be acquired upon such exercise are to be acquired for investment and not for resale or with a view to the distribution thereof. Upon such demand, delivery of such representation prior to the
delivery of any shares issued upon exercise of an option and prior to the expiration of the option period shall be a condition precedent to the right of the optionee or such other person to purchase any shares. 
 (h) Incentive Stock Options. Each option agreement which provides for the grant of an Incentive Stock Option to a participant shall
contain such terms and provisions as the Committee may determine to be necessary or desirable in order to qualify such option as an “incentive stock option” within the meaning of Section 422 of the Code, or any amendment thereof or
substitute therefor. Energen, in its discretion, may retain possession of any certificates for Stock delivered in connection with the exercise of an Incentive Stock Option or appropriately legend such certificates

  

 8 









 
during the period that a disposition of such Stock would disqualify the exercised option from treatment as an incentive stock option under Section 422 of the Code (a “422 Option”).
Subject to the other provisions of the Plan, Energen shall cooperate with the optionee should the optionee desire to make a disqualifying disposition. Any Incentive Stock Option which is disqualified from treatment as a 422 Option for whatever
reason, shall automatically become a Nonqualified Stock Option. No party has any obligation or responsibility to maintain an Incentive Stock Option’s status as a 422 Option. The optionee shall, however, immediately notify Energen of any
disposition of Stock which would cause an Incentive Stock Option to be disqualified as a 422 Option. 
 (i) Stock
Appreciation Right. Each option agreement may provide that the optionee may from time to time elect, by written notice to Energen, to cancel all or any portion of the option then subject to exercise, in which event Energen’s obligation in
respect of such option shall be discharged by payment to the optionee of an amount in cash equal to the excess, if any, of the Fair Market Value as of the Exercise Date of the shares subject to the option or the portion thereof so canceled over the
aggregate purchase price for such shares as set forth in the option agreement or, if mutually agreed by the Committee and the optionee, (i) the issuance or transfer to the optionee of shares of Stock with a Fair Market Value as of the Exercise
Date equal to any such excess, or (ii) a combination of cash and shares of Stock with a combined value as of the Exercise Date equal to any such excess. 
 (j) Dividend Equivalents. Each option agreement may provide that upon (i) exercise of all or part of an option, (ii) cancellation of all or part of such option pursuant to
paragraph 5(i), or (iii) the occurrence of an Expiration Date, for no additional consideration, the optionee shall be paid an additional amount equal to the aggregate amount of cash dividends which would have been paid on the shares of
Stock purchased upon such exercise or with respect to which such cancellation or expiration occurs, if such shares had been issued and outstanding during the period commencing with the option grant date and ending on the date of option exercise,
cancellation or expiration, plus an amount equal to the interest that such dividends would have earned from the respective dividend payment dates if deposited in an account bearing interest, compounded quarterly on each
April 1, July 1, October 1 and January 1, at a rate calculated as follows. For purposes of the preceding sentence, the assumed interest rate in effect for a calendar quarter shall be the U.S. bank prime rate published
by The Wall Street Journal in its “Money Rate” tables (or such comparable rate as the Committee may from time to time determine) in effect on the first day of such calendar quarter. Such additional amount shall be paid by cash, or
if mutually agreed by the Committee and the optionee, by the issuance of Stock or a combination of cash and shares of Stock having an aggregate Fair Market Value as of the applicable Expiration or Exercise Date, equal to any such excess. 

(k) No Rights as Shareholder. No optionee shall have any rights as a shareholder with respect to any shares subject to the
optionee’s option prior to the date of issuance to the optionee of a certificate or certificates for such shares. 
 (l)
Delivery of Certificates. Subject to Section 6.2(h), as soon as reasonably practicable after receipt of an exercise notice and full payment, Energen shall deliver to the optionee, registered in the optionee’s name, certificates for
the appropriate number of shares of Stock. 
  

 9 









 7. Restricted Stock 
 7.1 Grant of Restricted Stock. The Committee may make grants of Restricted Stock to Participants. Each restricted Stock Award shall be
evidenced by a written agreement setting forth the number of shares of Restricted Stock granted and the terms and conditions to which the Restricted Stock is subject. Restricted Stock may be awarded by the Committee in its discretion with or without
cash consideration. 
 7.2 Terms and Conditions of Restricted Stock. 
 (a) Restrictions. No shares of Restricted Stock may be sold, assigned, transferred, pledged, hypothecated, or otherwise encumbered or
disposed of (the “Restrictions”) until the Restrictions on such shares have lapsed or been removed. 
 (b) Lapse.
The Committee shall establish as to each Award of Restricted Stock the terms and conditions upon which the Restrictions shall lapse, which terms and conditions may include, without limitation, a required period of service, Performance Measures,
or any other individual or corporate performance conditions. 
 (c) Termination of Employment. In the event of a
Qualified Termination, then all restrictions on the Participant’s outstanding Restricted Stock (subject to the pre-Change in Control grant date limitation of Section 1(w)(5)) shall immediately lapse. Should a Participant’s employment
with Energen and all Subsidiaries terminate for any reason other than a Qualified Termination, any shares of the Participant’s Stock which remain subject to Restrictions, shall be forfeited and returned to Energen. The foregoing
notwithstanding, the Committee may at the time of grant provide for different or supplemental terms and conditions with respect to termination of employment and any such terms and conditions expressly provided in the written Restricted Stock
agreement shall be controlling with respect to that grant of Restricted Stock. 
 (d) Lapse at Discretion of Committee.
The Committee may at any time, in its sole discretion, accelerate the time at which any or all Restrictions on a Restricted Stock Award will lapse or remove any and all such Restrictions; provided that the Committee may not accelerate the lapse
of or remove Restrictions which require the attainment of a Performance Measure except as may be permitted by the performance-based exception to Section 162(m) of the Code. 
 (e) Rights with respect to Restricted Stock. Upon the acceptance by a Participant of an award of Restricted Stock, such Participant
shall, subject to the restrictions set forth in paragraph (b) above, have all the rights of a shareholder with respect to such shares of Restricted Stock, including, but not limited to, the right to vote such shares of Restricted Stock and the
right to receive all dividends and other distributions paid thereon. Certificates representing Restricted Stock may be held by Energen until the restrictions lapse and shall bear such restrictive legends as Energen shall deem appropriate.

 (f) No Section 83(b) Election. Unless otherwise expressly agreed in writing by Energen, a Participant shall not
make an election under Section 83(b) of the Code with respect to a Restricted Stock Award and upon the making of any such election, all shares of Restricted Stock subject to the election shall be forfeited and returned to Energen. 

 

 10 









 8. Performance Shares 
 8.1 Grant of Performance Shares 
 (a) The Committee may from time to time select employees to receive Performance Shares under the Plan. An Employee may be granted more than one Performance Share Award under the Plan. In its discretion at
the time of grant, the Committee may determine that an Interim Period or Interim Periods should be established for payment with respect to Performance Share Awards. Whenever Interim Periods are established, the terms and conditions with respect to
payment after the end of such Interim Period shall be those set by the Committee. 
 (b) A Performance Share Award shall not
entitle a Participant to receive any dividends or dividend equivalents on Performance Shares; no Participant shall be entitled to exercise any voting or other rights of a stockholder with respect to any Performance Share Award under the Plan; and no
Participant shall have any interest in or rights to receive any shares of Stock prior to the time when the committee determines the form of payment of Performance Shares pursuant to Section 8.2. 
 (c) Payment of a Performance Share Award to any Participant shall be made in accordance with Section 8.2 and shall be subject to such
conditions for payment as the Committee may prescribe at the time the Performance Share Award is made. The Committee may prescribe conditions such that payment of a Performance Share Award may be made with respect to a number of shares of Stock
greater than the number of Performance Shares awarded. The Committee may prescribe different conditions for different Participants. 
 (d) Each Performance Share Award shall be made in writing and shall set forth the terms and conditions set by the Committee for payment of such Performance Share Award. 
 8.2 Payment of Performance Share Awards 
 Each Participant granted a Performance Share Award shall be entitled to payment on account thereof as of the close of the applicable Award Period, but only if the Committee has determined that the
conditions for payment of the Award set by the Committee have been satisfied. Participants granted Awards with Interim Periods shall be entitled to partial payment on account thereof as of the close of the Interim Period, but only if the Committee
has determined that the conditions for partial payment of the Award set by the Committee have been satisfied. Performance Shares paid to a Participant for an Interim Period need not be repaid to Energen, notwithstanding that, based on the conditions
set for payment at the end of the Award Period, such Participant would not have been entitled to payment of any portion of such Award. Any Performance Shares paid to a Participant for the Interim Period during an Award Period shall be deducted from
the Performance Shares to which such Participant is entitled at the end of the Award Period. 
 Payment of Awards shall be made
by Energen promptly following the determination by the Committee that payment has been earned. Payment shall be made in the form of shares of Stock. 
  

 11 









 8.3 Termination of Employment 
 Except in the case of a Qualified Termination, if, prior to the close of the Award Period with respect to a Performance Share Award, a
Participant’s employment with Energen and all Subsidiaries terminates, then any unpaid portion of such Participant’s Performance Share Award shall be forfeited. In the case of a Qualified Termination, the Participant shall remain entitled
to payout of any outstanding Performance Share Awards (subject to the retirement reduction described below) at the end of the applicable Award Period in accordance with the terms of this Plan including without limitation applicable performance
conditions. 
 Retirement. If the Participant’s termination satisfies only that part of the Qualified Termination
definition related to retirement (Section 1(w)(4)), then this paragraph applies. If the Participant, having reached Retirement Date as defined under the Energen Corporation Retirement Income Plan, as amended from time to time, retires prior to the
end of the first twelve months of an Award Period (the “Initial Fiscal Year”), the number of Performance Shares for such Award shall be reduced. The reduced Award shall equal the number of Performance Shares originally granted multiplied
by a fraction the numerator of which is the number of Initial Fiscal Year months which occur prior to retirement and the denominator of which is 12. For example, assuming a calendar fiscal year, if the original Award was for 1,000 Performance Shares
and the Participant retired on April 1 of the Initial Fiscal Year, the size of the Award would be reduced by 75% to 250 Performance Shares, with the payment of such 250 Performance Shares remaining subject to the applicable Performance
Conditions for the full Award Period and the remaining 750 Performance Shares being forfeited. 
 8.4 Consulting, Non-Compete
and Confidentiality 
 A Participant’s entitlement, if any, to payout of Performance Share Awards subsequent to
termination of employment with Energen and all Subsidiaries shall continue so long as the Participant is in compliance with the following requirements. Failure to comply shall result in forfeiture of all then outstanding Performance Share Awards.

 (a) Consulting Services. For a period of three years following the termination of the Participant’s employment
(“Date of Termination”), Participant will fully assist and cooperate with Energen, the Subsidiaries and their representatives (including outside auditors, counsel and consultants) with respect to any matters with which the Participant was
involved during the course of employment, including being available upon reasonable notice for interviews, consultation, and litigation preparation. Except as otherwise agreed by Participant, Participant’s obligation under this
Section 8(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 Energen and the Subsidiaries but scheduled to accommodate Participant’s
reasonable scheduling requirements. Participant shall receive no additional fee for such services but shall be reimbursed all reasonable out-of-pocket expenses. 
 (b) Non-Compete. For a period of twelve months following the Date of Termination, unless otherwise expressly approved in writing by Energen, the Participant shall not Compete, (as defined below) or
assist others in Competing with Energen and the Subsidiaries. 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 oil or gas mineral interest in the State of Alabama. Employment by, or an

  

 12 









 
investment of less than one percent of equity capital in, a person or entity which Competes with Energen or the Subsidiaries does not constitute Competition by Participant so long as Participant
does not directly participate in, assist or advise with respect to such Competition. 
 (c) Confidentiality. Participant
agrees that at all times following the Date of Termination, Participant will not, without the prior written consent of Energen, disclose to any person, firm or corporation any confidential information of Energen or the Subsidiaries which is now
known to Participant or which hereafter may become known to Participant as a result of Participant’s employment, 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 provision. 
 8.5 No Assignment of Interest 
 The interest of any person in the Plan shall not be assignable, either by voluntary assignment or by operation of law, and any assignment of such interest, whether voluntary or by operation of law, shall
render the Award void. Amounts payable under the Plan shall be transferable only by will or by the laws of descent and distribution. 
 9. Withholding. Each Participant shall, no later than the date as of which the value of an Award first becomes includable in the gross income of the Participant for Federal income tax purposes, pay to Energen and Subsidiaries, or
make arrangements satisfactory to the Committee, in its sole discretion, regarding payment of, any Federal, FICA, state, or local taxes of any kind required by law to be withheld with respect to the Award. The obligations of Energen under the Plan
shall be conditional on such payment or arrangements. Energen and, where applicable, its Subsidiaries shall, to the extent permitted by law, have the right to deduct any such taxes owed hereunder by a Participant from any payment of any kind
otherwise due to said Participant. The Committee may permit Participants to elect to satisfy their Federal, and where applicable, FICA, state and local tax withholding obligations with respect to all Awards by the reduction, in an amount necessary
to pay all said withholding tax obligations, of the number of shares of Stock or amount of cash otherwise issuable or payable to said Participants in respect of an Award. 
 10. Performance Measures. At its discretion, the Committee may make the Awards subject to the attainment of one or more Performance Measures designed to qualify for the performance-based exceptions
from Section 162(m) of the Code. 
 Unless and until Energen’s shareholders approve a change in the Performance Measures set forth in
this Section 10, the Performance Measures to be used for purposes of such Awards shall be chosen from among the following alternatives, as measured with respect to Energen and/or any one or more of the Subsidiaries, with or without comparison
to a peer group: 
  

	 	(a)	return on shareholder’s equity; 

  

 13 










	 	(b)	return on assets; 

  

	 	(c)	net income; 

  

	 	(d)	earnings per common share; 

  

	 	(e)	total shareholder return; 

  

	 	(f)	oil and/or gas reserve additions; 

  

	 	(g)	utility customer number, volume and/or revenue growth; and 

  

	 	(h)	such other criteria as may be established by the Committee in writing and which meets the requirements of the performance-based exception to Section 162(m) of the
Code. 

 In the event that the performance-based exception to Section 162(m) or its successor is amended such that the
performance-based exception permits the employer to alter the governing performance measures without obtaining shareholder approval of such changes, the Committee shall have discretion to make such changes without obtaining shareholder approval

 11. No Rights to Continued Employment. The Plan and any Award granted under the Plan shall not confer upon any
Participant any right with respect to continuance of employment by Energen or any Subsidiary or any right to further Awards under the Plan, nor shall they interfere in any way with the right of Energen or any Subsidiary by which a Participant is
employed to terminate the Participant’s employment at any time. 
 12. Compliance with Other Laws and Regulations.
The Plan, the grant and fulfillment of Awards thereunder, and the obligations of Energen to sell, issue, release and/or deliver shares of Stock shall be subject to all applicable federal and state laws, rules, and regulations and to such approvals
by any government or regulatory agency as may be required. Energen shall not be required to issue or deliver any certificates for shares of Stock prior to (a) the listing of such shares on any stock exchange on which the Stock may then be
listed and (b) the completion of any registration or qualification of such shares under any federal or state law, or any ruling or regulation of any government body which Energen shall, in its sole discretion, determine to be necessary or
advisable. 
 13. Change in Control. This Section 13 applies only with respect to Awards granted prior to
January 1, 2010. A Change in Control shall not constitute an “Acceleration Event” with respect to any Award granted on or after January 1, 2010. 
  


 14 









 13.1 Acceleration Event. For purposes of this Section 13, “Acceleration
Event” means the occurrence of a Change in Control described in clauses (2), (3), (4), or (5)(i) of the Section 1(e) definition of Change in Control. 
 13.2 Options, Restricted Stock. Except as may be otherwise expressly provided in the applicable Award agreement, upon the occurrence of an Acceleration Event, all outstanding Incentive Stock
Options and Nonqualified Stock Options shall be immediately and fully vested and exercisable and all restrictions on all outstanding Restricted Stock shall immediately lapse. (Also see Sections 1(w)(5), 6.2(e) and 7.2(c)) 
 13.3 Performance Shares. 
 (a) Payment Acceleration. If an Acceleration Event occurs, all outstanding Performance Share Awards shall be valued as soon after the date of such Acceleration Event as practicable. Valuation of
the Performance Share awards shall be based on satisfaction of the applicable performance conditions measured as if all Award Periods had ended at the close of Energen’s last whole fiscal year prior to the date of the Acceleration Event,
provided that for purposes of any performance conditions involving the price of the Common Stock or payment of dividends, stock shall be priced equal to its Measurement Value based on the twenty trading days immediately preceding the date of such
Acceleration Event and the period for dividend measurement shall extend to and include the day immediately prior to the date of the Acceleration Event. As soon as practicable following the completion of such valuation, all outstanding Performance
Share Awards shall be paid based on such valuation. 
 (b) Independent Auditor. Following an Acceleration Event, all
calculations with respect to performance measurement and Award payment shall be made by the Independent Auditor at the expense of Energen. The Independent Auditor shall resolve any procedural ambiguities discovered in making such calculations using
its own judgment and discretion in light of the purposes of the Plan and past practices in calculating Performance Share Award payments. 
 13.4 Payment of Professional Fees and Expenses. If a Change in Control occurs, Energen shall pay promptly as incurred all legal, accounting and other professional fees and expenses (collectively,
“Professional Fees”) which a Participant may reasonably incur as a result of any contest (regardless of the outcome thereof) by Energen, Participant or others of the validity or enforceability of, or liability under, any provision of the
Plan (including as a result of any contest by Executive about the amount of any payment pursuant to the Plan), 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.
In addition Energen shall promptly pay to Participant an additional amount (the “Tax Reimbursement Payment”) such that the net amount retained by the Participant with respect to all payments made under this paragraph 13.4 after deduction
of Taxes, shall be equal to the amount of the Professional Fees reimbursement plus applicable interest. For purposes of this Section 13.4, “Taxes” means all federal, state and local, employment and income taxes payable or withheld
with respect to Professional Fees reimbursement payments (excluding interest) and Tax Reimbursement payments. The Independent Auditor, at Energen’s expense, shall make all calculations with respect to the Tax Reimbursement Payment and in making
such calculations shall assume that Participant is subject to the highest marginal tax rates.

 14. Amendment and Discontinuance. The Board of Directors of Energen may from time to
time amend, suspend or discontinue the Plan. Subject to Section 18, without the written consent of a Participant, no amendment or suspension of the Plan shall alter or impair any Award previously granted to a Participant under the Plan.

 15. Effective Date of the Plan. The effective date of the Plan shall be November 25, 1997, the date of its
adoption by the Board, subject to approval by shareholders of Energen holding not less than a majority of the shares present and voting at its January 1998 Annual Meeting. Awards may be granted under the Plan by the Committee as provided herein
prior but subject to such subsequent shareholder approval of the Plan. 
 16. Name. The Plan shall be known as the
“Energen Corporation 1997 Stock Incentive Plan.” 
 17. 1997 Deferred Compensation Plan. If and to the extent
permitted under the Energen Corporation 1997 Deferred Compensation Plan (the “Deferred Compensation Plan”), a Participant may elect, pursuant to the Deferred Compensation Plan, to defer receipt of part or all of any shares of Stock or
other consideration deliverable under an Award and upon such deferral shall have no further right with respect to such deferred Award other than as provided under the Deferred Compensation Plan. In the event of such a deferral election, certificates
for such shares of Stock as would have otherwise been issued under the Plan but for the deferral election, may at the discretion of Energen be delivered to the Trustee under the Deferred Compensation Plan and registered in the name of the Trustee or
such other person as the Trustee may direct. Regardless of whether such deferred shares of Stock are issued to the Trustee, they shall constitute “issued” shares for purposes of the Plan’s maximum number of shares limitation set forth
in Section 2. 
 18. Effect of Code Section 409A. Payments and benefits under this Plan are intended to
comply with Section 409A of the Code (“Code Section 409A”) and all provisions of the Plan shall be interpreted in accordance with Code 409A and Department of Treasury regulations and other interpretive guidance issued thereunder,
including without limitation any such regulations or other guidance that may be issued after the date hereof. Notwithstanding any provision of the Plan to the contrary, in the event that Energen determines that any payments or benefits may or do not
comply with Section 409A, Energen may amend the Plan (without Participant consent) or take any other actions that Energen determines are necessary or appropriate to (i) exempt the payments or benefits hereunder from the application of Code
Section 409A or preserve the intended tax treatment of the payments and benefits provided hereunder, or (ii) comply with the requirements of Code Section 409A.
