either (i) the then outstanding shares of common stock of the Company (the “Outstanding Common Stock”) or (ii) the combined voting power of the then outstanding voting

 4. TERMS AND CONDITIONS OF INCENTIVES. 

4.1 ESTABLISHMENT OF PERFORMANCE OBJECTIVES AND INCENTIVE OPPORTUNITY. Within 90 days of the commencement of each Plan Year
(or such later time as may be permitted for performance-based compensation under Section 162(m)), the Committee shall establish written performance objectives and a cash incentive opportunity for each Participant chosen to receive an incentive
for such Plan Year. At the time of setting the performance objectives, the Committee shall specify the formula to be used in calculating each of the criteria on which an incentive is based and their relative weights. The incentive opportunity shall
be expressed as an amount of cash or percentage of salary. The Committee may also specify a minimum acceptable level of achievement of the relevant performance objectives, as well as one or more additional levels of achievement, and a formula to
determine the percentage of the incentive opportunity earned by the employee upon attainment of each such level of achievement. The performance objectives and incentive opportunity relating to any particular incentive need not be the same as those
relating to any other incentive, whether made at the same or a different time. The Committee may delegate to the Chief Executive Officer of the Company the establishment and measurement of such performance objectives for Participants who are not
Covered Employees.

during the Performance Period: 
  

	 	(1)	asset write-downs, sales and dispositions; 

  

	 	(2)	litigation, claims, judgments or settlements;

	 	(ii)	as described in management’s discussion and analysis of financial condition and results of operations appearing in the Company’s Annual Report to stockholders
for the applicable year, or 

  

	 	(iii)	as publicly announced by the Company in a press release or conference call relating to the Company’s results of operations or financial condition for a completed
quarterly or annual fiscal period; such as non-cash mark-to-market gains and losses on open derivative contracts. 

(c) Per Share Adjustments. Performance objectives set on a per share basis such as earnings or cash flow per share shall be
appropriately adjusted to reflect changes in outstanding shares resulting from stock dividends, splits or combinations or mergers, reorganizations or similar transactions. 
 (d) Non-Covered Employees. The performance objectives for Participants who are not Covered Employees may be based on Section 162(m) Criteria or on criteria different from or supplemental to
the Section 162(m) Criteria. 
 4.3 EARNING OF INCENTIVE, INDIVIDUAL MAXIMUM. Promptly after the date on which the
necessary information for a particular Plan Year becomes available, the Committee shall determine the extent to which the incentive opportunity for such Plan Year has been earned through the achievement of the relevant performance objectives by each
Participant who was granted an incentive for such Plan Year. At its discretion, the Committee may reduce a Participant’s earned incentive by up to 25%. The Committee shall certify in writing the earned incentives adjusted for any discretionary
reductions. Notwithstanding the terms of any incentive, the maximum incentive under this Plan to any individual for any one Plan Year shall not exceed $2.5 million. 
 4.4 PAYMENT OF INCENTIVES. Promptly after the Committee has certified in writing that an incentive has been earned and any discretionary reductions, such incentives shall be paid in cash in a lump
sum, provided, that any amounts, the payment of which has been deferred under the Energen Corporation 1997 Deferred Compensation Plan or any successor plan, shall be credited to the Participant’s account in accordance with the terms of that
plan. 
 4.5 TERMINATION OF EMPLOYMENT – COMPLETED PLAN YEAR. If Participant’s employment is terminated for any
reason (including death, disability or retirement) other than Cause after the end of a Plan Year but before payment of incentives for such Plan Year, the Participant shall remain entitled to payment of incentives, if any, earned for such Plan Year.
A Participant whose employment is terminated for Cause after the end of a Plan Year but before payment of incentives for such Plan Year shall not receive payment of any incentive for the completed Plan Year. 

  
 7 

 4.6 TERMINATION OF EMPLOYMENT – PARTIAL PLAN YEAR – NO CHANGE IN
CONTROL. If prior to the last day of a Plan Year during which a Change in Control does not occur (a “Routine Plan Year”), a Participant’s employment terminates as a result of the Participant’s death, disability, or retirement
under the terms of any retirement plan maintained by the Company or a Subsidiary, such Participant shall receive an incentive equal to the amount that the Participant would have received as an incentive if such Participant had remained an employee
through the end of the Plan Year multiplied by a fraction, the numerator of which is the number of days that elapsed during the Plan Year in which the termination occurs prior to and including the date of the Participant’s termination of
employment and the denominator of which is the number of days in the full Plan Year (a “pro rata incentive”). If a Participant’s employment terminates for any other reason during a Routine Plan Year, then no incentive shall be payable
to the Participant for such Plan Year, provided, that at its discretion, the Committee may determine to pay such Participant (other than a Participant terminated for cause) up to a pro rata incentive. 

4.7 TERMINATION OF EMPLOYMENT – PARTIAL PLAN YEAR – WITH CHANGE IN CONTROL. If prior to the last day of a Plan Year
during which a Change in Control occurs (a “Change in Control Plan Year”), 
  

	 	(i)	a Participant’s employment terminates as a result of the Participant’s death, disability, or retirement under the terms of any retirement plan maintained by
the Company or a Subsidiary, or 

  

	 	(ii)	after the occurrence of the Change in Control, the Participant’s employment is otherwise involuntarily terminated other than for Cause, including a termination for
good reason entitling the Participant to severance compensation under a written change in control severance compensation agreement between the Company or a Subsidary and the Participant; 

such Participant shall receive an incentive equal to the Participant’s target incentive for the Plan Year multiplied by a fraction, the numerator of
which is the number of days that elapsed during the Plan Year in which the termination occurs prior to and including the date of the Participant’s termination of employment and the denominator of which is the number of days in the full Plan
Year (a “pro rata incentive”). If a Participant’s employment terminates for any other reason during a Change in Control Plan Year, then no incentive shall be payable to the Participant for such Plan Year, provided, that at its
discretion, the Committee may determine to pay such Participant (other than a Participant terminated for cause) up to a pro rata incentive.

any one Energen fiscal year shall not exceed 400,000 calculated assuming maximum payout of the Awards and with each Performance Share representing one share of Stock; (ii) the maximum number of shares of Stock represented by all Restricted
Stock and Performance Share Awards granted on or after April 27, 2011, shall not exceed 1,500,000; and (iii) the maximum number of shares of stock represented by Incentive Stock Options granted on or after April 27, 2011 shall not
exceed 3,794,326. 
 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 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. 

  
 5 

 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; provided, however, that (i) no Incentive Stock Option shall be
granted after the expiration of ten years from the ISO Effective Date as defined in Section 14 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 Shareholder, such period, including extensions, shall not exceed five years from the date of grant. 

  
 6 

 (b) Option Price, No Repricing. 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 Shareholder, 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. Except as otherwise permitted by Section 3, the terms of outstanding Awards may not be amended to reduce the exercise price
of outstanding options or stock appreciation rights or cancel outstanding options or stock appreciation rights in exchange for cash, other awards or options with an exercise price that is less than the exercise price of the original options or stock
appreciation rights without shareholder approval. 
 (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 Termination of Employment. 

 

	 	(1)	Cause. 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. 
  

	 	(2)	Qualified Termination. In the event of a Qualified Termination, then all options held by the optionee with a grant date at least ten months prior to the date of
termination shall be immediately and fully vested and options with a grant date less than ten months prior to the date of termination shall immediately expire. 

  
 7 

	 	(3)	Change in Control Termination. In the event of a Change in Control Termination, all options held by the optionee which were granted prior to the Change in
Control shall be immediately and fully vested. 

  

	 	(4)	Adjusted Option Expiration Date. Following a termination of employment any vested options held by the terminated employee will expire on the applicable Adjusted
Option Expiration Date. 

  

	 	(5)	Committee Authority. The foregoing provisions of this Section 6.2(e) notwithstanding, 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 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. Furthermore, 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.

  

	 	(6)	Options Granted Prior to January 31, 2012. The other provisions of this Section 6.2(e) notwithstanding, the provisions of Section 6.2(e) of the
Energen Corporation Stock Incentive Plan as Amended effective April 27, 2011, continue to control the manner in which options granted prior to January 31, 2012, will be treated upon a termination of employment.

 (f) Nontransferability. Except as may otherwise be provided in this Section 6.2(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 Energen for such a representation, the optionee shall deliver to Energen at the time of any exercise of an option or portion thereof or settlement of stock appreciation rights 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. 

  
 8 

 (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. As provided in Section 6.1, no Incentive Stock Option shall be granted after the expiration of ten years from the ISO Effective Date as defined in Section 14.
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 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) 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. 
 (k) Issuance of Shares. Subject to Section 6.2(h), as soon asreasonably practicable after receipt of an exercise notice and full payment, Energen shall issue to the optionee the appropriate
number of shares of Stock. 
 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. 

  
 9 

 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 with a grant date at least ten months prior to the date of termination shall immediately lapse and Restricted Stock with a grant date less than ten
months prior to the date of termination shall be forfeited and returned to Energen. In the event of a Change in Control Termination, all restrictions on the Participant’s outstanding Restricted Stock shall immediately lapse. Should a
Participant’s employment with Energen and all Subsidiaries terminate for any reason other than a Qualified Termination or a Change in Control 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 (a) 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. 

(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 shareholder 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 authorizes 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 or otherwise reference 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. Payment of Awards shall be made by Energen promptly following the determination by the Committee that payment has
been earned and by March 15 of the year following the year in which the Award is earned. Payment shall be made in the form of shares of Stock. 
 8.3 Termination of Employment 
 Except in the case of a Qualified
Termination or a Change in Control 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 with a grant date at least ten months prior to the date of termination (subject to the 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. Each of such outstanding Performance Share Awards shall be reduced to equal the number of Performance Shares originally granted multiplied by a fraction the numerator
of which is the number of months from the grant date to the termination date and the denominator of which is the number of months in the applicable Award Period. 

  
 11 

 In the event of a Change in Control Termination, a Participant shall within thirty days
following termination receive payment of all outstanding Performance Share Awards measured at target performance. 
 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 8.4(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 (A) within an oil or gas unit for which Energen Resources Corporation is the operator of record or (B) within an oil or gas unit contiguous to an oil or gas unit for which Energen Resources Corporation is the operator of record.
Employment by, or an 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. 

  
 12 

 8.5 No Assignment of Interest 

Except as provided in Section 6.2(f), 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, state or local income tax purposes, pay to Energen and Subsidiaries, or make arrangements satisfactory to the Committee, in its sole discretion, regarding payment of any Federal, state,
or local taxes of any kind required by law to be withheld with respect to the Award together with any Federal (including FICA and FUTA), state, or local employment taxes required to be withheld. 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, 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; 

  

	 	(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. 

  
 13 

 In the event that the performance-based exception to Section 162(m) of the Code 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. Amendment and Discontinuance. The Board may from time to time amend, suspend or discontinue
the Plan. Subject to Section 17, 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. 

14. Effective Date of the Plan. The original effective date of the Plan was November 25, 1997, the date of its adoption by the
Board, subject to approval by the shareholders of Energen holding not less than a majority of the shares present and voting at its January 1998 Annual Meeting. From time to time the Board has made amendments to the Plan that require shareholder
approval for effectiveness and the shareholders of Energen have approved such amendments, each of which is deemed to be a re-adoption by the Board and re-approval by the shareholders of the Plan for the purposes of Code Section 422(b)(2). The
“ISO Effective Date” is the earlier of the dates of such re-adoption and re-approval of the most recent shareholder approved Plan amendment or restatement. 
 15. Name. The Plan shall be known as the “Energen Corporation Stock Incentive Plan.” 
 16. 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. 

  
 14 

 17. Effect of Code Section 409A. Payments and benefits under this Plan
are intended to be exempt from the requirements under Code section 409A (“Code Section 409A”) and all provisions of the Plan shall be interpreted in accordance with the applicable exemptions. To the extent any payment or benefit is
subject to Code Section 409A, the Plan shall be interpreted in accordance with Code Section 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 Code 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. Without limiting the generality of the foregoing, if and to the extent that any payment or benefit under this Plan is
determined by Energen to constitute “nonqualified deferred compensation” subject to Code Section 409A, this Plan shall be administered accordingly, and any such payment provided to an employee who is a “specified employee”
(within the meaning of Code Section 409A and as determined pursuant to procedures established by Energen) must be delayed for six months from the date of employment termination to comply with section 409A(a)(2)(B)(i) of the Code. Energen shall
set aside those payments or benefits that would have been made but for payment delay required by the preceding sentence, and such amounts will be paid at the end of the delay.
