 As Amended and Restated Effective December 15, 2015 

Section 1 
 Introduction 

1.1 Establishment. Apache Corporation, a Delaware corporation (hereinafter referred to, together with its Affiliates (as defined below) as the
“Company” except where the context otherwise requires), previously established the Apache Corporation 2011 Omnibus Equity Compensation Plan, effective May 5, 2011, which plan was amended and restated effective May 16, 2013 and
February 3, 2014, and is hereby amended and restated effective December 15, 2015 (the “Plan”), as it may be further amended and restated from time to time. 

1.2 Purpose. The purpose of the Plan is to provide Eligible Persons designated by the Committee for participation in the Plan with equity-based
incentives to: (i) encourage such individuals to continue in the long-term service of the Company and its Affiliates, (ii) create in such individuals a more direct interest in the future success of the operations of the Company,
(iii) attract outstanding individuals, and (iv) retain and motivate such individuals. The Plan is intended to provide eligible individuals with the opportunity to invest in the Company, thereby relating incentive compensation to increases
in stockholder value and more closely aligning the compensation of such individuals with the interests of the Company’s stockholders. 
 Accordingly,
this Plan provides for the granting of Incentive Stock Options, Non-Qualified Stock Options, Performance Awards, Restricted Stock, Restricted Stock Units, Stock Appreciation Rights or any combination of the foregoing, as the Committee determines is
best suited to the circumstances of the particular individual as provided herein. 
 1.3 Effective Date. The Effective Date of the Plan (the
“Effective Date”) is May 5, 2011. This Plan and each Award granted hereunder are conditioned on and shall be of no force or effect until the Plan is approved by the stockholders of the Company. The Committee (or its delegate in
accordance with Section 3.4(b) hereof) may award grants, the entitlement to which shall be expressly subject to the condition that the Plan shall have been approved by the stockholders of the Company.

Plan; provided, however, that the Committee shall not have any discretion to accelerate, waive or modify any term or condition of an Award that is intended to qualify as “performance-based compensation” for purposes of Section 162(m)

interpretation of the Plan has been delegated against any cost or expense (including counsel fees) or liability (including any sum paid in settlement of a claim with the approval of the Committee) arising out of any action, omission or determination
relating to the Plan, unless, in either case, such action, omission or determination was taken or made by such member, director or employee in bad faith and without reasonable belief that it was in the best interests of the Company. The

Agent, who need not be a member of the Committee or an employee of the Company, to assist the Committee in administration of the Plan and to whom it may delegate such powers as the Committee deems appropriate, except that the Committee shall
determine any dispute. The Committee may correct any defect, supply any omission or reconcile any inconsistency in the Plan, or in any Award agreement entered into hereunder, in the manner and to the extent it shall deem expedient, and it shall be
the sole and final judge of such inconsistency; 

  

	 	(b)	The Committee has delegated authority to the Chief Executive Officer of the Company to grant Awards to employees of the Company who are not the Company’s executive officers (as such term is defined for purposes of
Section 16 of the Exchange Act) and who are below the level of Regional Vice President or Staff Vice President; provided, that any such Awards may only be granted in accordance with guidelines established by the Committee. 


3.5 Compliance with Section 162(m). Except as expressly otherwise stated in any resolution of the Committee, the Plan is intended to comply
with the requirements of Section 162(m) or any successor section(s) of the Internal Revenue Code (“Section 162(m)”) as to any “covered employee” as defined in Section 162(m), and shall be administered, interpreted, and
construed consistently therewith. The Committee is authorized to take such additional action, if any, that may be required to ensure that the Plan and any Award under the Plan satisfy the requirements of Section 162(m), taking into account any
regulations or other guidance issued by the Internal Revenue Service. 
 Section 4 

Stock Subject to the Plan 
 4.1 Number of
Shares. Subject to adjustments pursuant to Section 4.4 hereof, up to (a) 25,500,000 shares of Stock are authorized for issuance under the Plan plus (b) effective May 16, 2013, 17,000,000 additional shares of Stock are
authorized for issuance under the Plan in accordance with the Plan’s terms and subject to such restrictions or other provisions as the Committee may from time to time deem necessary. Notwithstanding the foregoing, the number of aggregate shares
of Stock available for issuance under the Plan at any given time shall be reduced by (i) 1.0 share for each share of Stock granted in the form of Stock Options or Stock Appreciation Rights, or (ii) 2.39 shares for each share of Stock
granted in the form of any Award that is not a Stock Option or Stock Appreciation Right. During the duration of the Plan, no Eligible Person may be granted Options which in the aggregate cover in excess of 5 percent of the total shares of Stock
authorized under the Plan. No Award may be granted under the Plan on or after the 10-year anniversary of the Effective Date. The foregoing to the contrary notwithstanding, within the aggregate limit described in the first sentence of this
Section 4.1, up to 25,500,000 (effective May 16, 2013, up to 42,500,000) shares of Stock may be issued pursuant to ISOs granted under the Plan. 

4.2 Availability of Shares Not Issued under Awards. If shares of Stock which may be issued pursuant to the terms of the Plan awarded hereunder
are forfeited, cancelled, exchanged or surrendered or if an Award otherwise terminates or expires without a distribution of shares to the holder of such 

  
 7 








 
Award, the shares of Stock with respect to such Award shall, to the extent of any such forfeiture, cancellation, exchange, surrender, termination or expiration, again be available for Awards
under the Plan; provided, however, that in such case, the number of shares of Stock that may be issued under the Plan shall increase by 1.0 share for each share related to a Stock Option or a Stock Appreciation Right that is so forfeited, cancelled,
exchanged or surrendered or expired and by 2.39 shares for each such share which is not related to a Stock Option or a Stock Appreciation Right. The number of shares available shall not be increased by shares tendered, surrendered or withheld in
connection with the exercise or settlement of an Award or the related tax withholding obligations. Furthermore, when a SAR is settled in shares, the number of shares subject to the SAR under the SAR Award agreement will be counted against the
aggregate number of shares with respect to which Awards may be granted under the Plan as one share for every share subject to the SAR, regardless of the number of shares used to settle the SAR upon exercise. 

4.3 Stock Offered. The Company shall at all times during the term of the Plan retain as authorized and unissued Stock and/or Stock in the
Company’s treasury, at least the number of shares from time to time require under the provisions of the Plan, or otherwise assure itself of its ability to perform its obligations hereunder. 

4.4 Adjustments for Stock Split, Stock Dividend, Etc. If the Company shall at any time increase or decrease the number of its outstanding shares
of Stock or change in any way the rights and privileges of such shares by means of the payment of a Stock dividend or any other distribution upon such shares payable in Stock or rights to acquire Stock, or through a Stock split, reverse Stock split,
subdivision, consolidation, combination, reclassification or recapitalization involving the Stock (any of the foregoing being herein called a “capital restructuring”), then in relation to the Stock that is affected by one or more of the
above events, the numbers, rights, and privileges of the following shall be, in each case, equitably and proportionally adjusted to take into account the occurrence of any of the above events, (i) the number and kind of shares of Stock or other
property (including cash) that may thereafter be issued pursuant to subsections 4.1 and 4.10, (ii) the number and kind of shares of Stock or other property (including cash) issued or issuable in respect of outstanding Awards; and (iii) the
exercise price, grant price, or purchase price relating to any Award; provided that, with respect to Incentive Stock Options, such adjustment shall be made in accordance with Section 424(h) of the Internal Revenue Code; (iv) the
Performance Goals, and (v) the individual limitations applicable to Awards. 
 4.5 Other Changes in Stock. In the event there shall be
any change, other than as specified in subsections 4.4 hereof, in the number or kind of outstanding shares of Stock or of any stock or other securities into which the Stock shall be changed or for which it shall have been exchanged, and if the
Committee shall in its discretion determine that such change equitably requires an adjustment in the number or kind of shares subject to outstanding Awards or which have been reserved for issuance pursuant to the Plan but are not then subject to an
Award, then such adjustments shall be made by the Committee and shall be effective for all purposes of the Plan and on each outstanding Award that involves the particular type of stock for which a change was effected. 

4.6 Rights to Subscribe. If the Company shall at any time grant to the holders of its Stock rights to subscribe pro rata for additional shares
thereof or for any other securities of the Company or of any other corporation, there shall be reserved with respect to the shares then under an outstanding Award to any Participant of the particular class of Stock involved the Stock or other
securities which the Participant would have been entitled to subscribe for if immediately prior to such grant the Participant had exercised his entire Option. If, upon exercise of any such Option, the Participant subscribes for the additional shares
or other securities, the aggregate Option Price shall be increased by the amount of the price that is payable by the Participant for such additional shares or other securities as if the Participant had exercised his entire Option immediately prior
to the grant of such additional shares or other securities. 

  
 8 








 4.7 General Adjustment Rules. No adjustment or substitution provided for in this Section 4
shall require the Company to sell a fractional share of Stock under any Option, or otherwise issue a fractional share of Stock, and the total substitution or adjustment with respect to each Option shall be limited by deleting any fractional share.
In the case of any such substitution or adjustment, the aggregate Option Price for the shares of Stock then subject to the Option shall remain unchanged but the Option Price per share under each such Option shall be equitably adjusted by the
Committee to reflect the greater or lesser number of shares of Stock or other securities into which the Stock subject to the Option may have been changed. 

4.8 Determination by the Committee, Etc. Adjustments under this Section 4 shall be made by the Committee, whose determinations with regard
thereto shall be final and binding upon all parties. 
 4.9 Code Section 409A. For any Award that is not subject to Internal Revenue Code
Section 409A before the adjustments identified in the preceding sections of this Section 4, no adjustment shall be made that would cause the Award to become subject to Internal Revenue Code Section 409A. For an Award that is subject
to Internal Revenue Code Section 409A before the adjustments identified in the preceding sections of this Section 4, no adjustment shall cause the Award to violate Internal Revenue Code Section 409A, without the prior written consent
of both the Participant and the Committee. 
  

	4.10	Award Limits. The following limits shall apply to grants of all Awards under the Plan: 

  

	 	(a)	Options: The maximum aggregate number of shares of Stock that may be subject to Options granted in any calendar year to any one Participant shall be 250,000 shares. 


 

	 	(b)	SARs: The maximum aggregate number of shares that may be subject to Stock Appreciation Rights granted in any calendar year to any one Participant shall be 250,000 shares. Any shares covered by Options
which include tandem SARs granted to one Participant in any calendar year shall reduce this limit on the number of shares subject to SARs that can be granted to such Participant in such calendar year.

shares). 

 To the extent required by Section 162(m) of the Code, shares subject to Options or SARs which are canceled shall continue to
be counted against the limits set forth in paragraphs (a) and (b) immediately preceding. 
 4.11 Repayment/Forfeiture of Awards. If
required by the Sarbanes-Oxley Act of 2002 and/or by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, each Participant’s Award shall be conditioned on repayment or forfeiture in accordance with applicable law and the
related Award agreement shall reflect any such condition. In addition, the Committee may establish such conditions for repayment or forfeiture of Awards as the Committee may adopt by policy for the Company or any Affiliate.

 Section 5 

Granting of Awards to Participants 
 5.1
Participation. Participants in the Plan shall be those Eligible Persons who, in the judgment of the Committee (or, pursuant to Section 3.4(b), the Chief Executive Officer of the Company), are performing, or during the term of
their incentive arrangement will perform, vital services in the management, operation, and development of the Company or an Affiliate, and significantly contribute, or are expected to significantly contribute, to the achievement of the
Company’s long-term corporate economic objectives. Participants may be granted from time to time one or more Awards; provided, however, that the grant of each such Award shall be separately approved by the Committee or granted in accordance
with Section 3.4(b) hereof, and receipt of one such Award shall not result in automatic receipt of any other Award. Upon determination that an Award is to be granted to a Participant, as soon as practicable, written notice shall be given to
such person, specifying the terms, conditions, rights and duties related thereto. Each Participant shall, if required by the Committee, enter into an agreement with the Company, in such form as the Committee shall determine and which is consistent
with the provisions of the Plan, specifying such terms, conditions, rights, and duties. Awards shall be deemed to be granted as of the date specified in the grant resolution of the Committee (or, in the case of grants made pursuant to
Section 3.4(b), in accordance with the guidelines established by the Committee), which date shall be the date of any related agreement with the Participant. In the event of any inconsistency between the provisions of the Plan and any such
agreement entered into hereunder, the provisions of the Plan shall govern. 
 Awards granted to members of the Board shall be recommended to the full Board
by the Management Development and Compensation Committee and approved by the full Board. 
 5.2 Notification to Participants and Delivery of
Documents. As soon as practicable after such determinations have been made, each Participant shall be notified of (a) his/her designation as a Participant, (b) the date of grant, (c) the number and type of Awards granted to
the Participant, (d) in the case of Performance Awards, the Performance Period and Performance Goals, (e) in the case of Restricted Stock or Restricted Stock Units, the Restriction Period (as defined in subsection 8.1), and (f) any
other terms or conditions imposed by the Committee with respect to the Award. 
 5.3 Delivery of Award Agreement. This requirement for
delivery of a written Award agreement is satisfied by electronic delivery of such agreement provided that evidence of the Participant’s receipt of such electronic delivery is available to the Company and such delivery is not prohibited by
applicable laws and regulations.

6.2 Stock Option Agreements. Each Option granted under the Plan shall be identified as either an Incentive Stock Option or a Non-Qualified Stock

	 	(c)	No Backdating. There shall be no backdating of Options, and each Option shall be dated the actual date that the Committee adopts the resolution awarding the grant of such Option. 


 

	 	(d)	Limitations on Incentive Stock Options. No Incentive Stock Option may be granted to an individual if, at the time of the proposed grant, such individual owns (or is attributed to own by virtue of the
Internal Revenue Code) Stock possessing more than 10 percent of the total combined voting power of all classes of stock of the Company or any Affiliate unless (i) the exercise price of such Incentive Stock Option is at least 110 percent of the
Fair Market Value of a share of Stock at the time such Incentive Stock Option is granted and (ii) such Incentive Stock Option is not exercisable after the expiration of five years from the date such Incentive Stock Option is granted.


 To the extent that the aggregate Fair Market Value of Stock of the Company with respect to which Incentive Stock Options are exercisable
for the first time by a Participant during any calendar year under the Plan and any other option plan of the Company (or any Affiliate) shall exceed $100,000, such Options shall be treated as Non-Qualified Stock Options. Such Fair Market Value shall
be determined as of the date on which each such Incentive Stock Option is granted. 
  

	 	(e)	Duration of Options. Each Stock Option agreement shall state the period of time, determined by the Committee, within which the Option may be exercised by the Participant (the “Option Period”).
The Option Period must end, in all cases, not more than ten years from the date an Option is granted. 


  
 11 









	 	(f)	Termination of Options. During the lifetime of a Participant to whom a Stock Option is granted, the Stock Option may be exercised only by such Participant or, in the case of disability (as determined
pursuant to the Company’s Long-Term Disability Plan or any successor plan) by the Participant’s designated legal representative, except to the extent such exercise would cause any Award intended to qualify as an ISO not to so qualify. Once
a Participant to whom a Stock Option was granted dies, the Stock Option may be exercised only by the personal representative of the Participant’s estate or, with respect to Stock Options that are not Incentive Stock Options, as otherwise
provided in Section 14.2. Unless the Stock Option agreement shall specify a longer or shorter period, at the discretion of the Committee, then the Participant (or representative, or, if applicable pursuant to Section 14.2, designated
beneficiary) may exercise the Stock Option for a period of up to three months after such Participant terminates employment or ceases to be a member of the Board. 


 

	 	(g)	Exercise, Payments, Etc. 

 (i) Each Stock Option agreement shall provide that the
method for exercising the Option granted therein shall be by delivery to the Office of the Secretary of the Company or to the Administrative Agent of written notice specifying the number of shares of Stock with respect to which such Option is
exercised and payment to the Company of the aggregate Option Price. Such notice shall be in a form satisfactory to the Committee and shall specify the particular Options (or portions thereof) which are being exercised and the number of shares of
Stock with respect to which the Options are being exercised. The Participant’s obligation to deliver written notice of exercise is satisfied by electronic delivery of such notice through means satisfactory to the Committee and prescribed by the
Company. The exercise of the Option shall be deemed effective on the date such notice is received by the Office of the Secretary or by the Administrative Agent and payment is made to the Company of the aggregate Option Price (the “Exercise
Date”); however, if payment of the aggregate Option Price is made pursuant to a sale of shares of Stock as contemplated by subsection 6.2(g)(iv)(E) below, the Exercise Date shall be deemed to be the date of such sale. If requested by the
Company, such notice shall contain the Participant’s representation that he or she is purchasing the Stock for investment purposes only and his or her agreement not to sell any Stock so purchased in any manner that is in violation of the
Exchange Act or any applicable state law, and such restriction, or notice thereof, shall be placed on the certificates representing the Stock so purchased. The purchase of such Stock shall take place upon delivery of such notice to the Office of the
Secretary of the Company or to the Administrative Agent, at which time the aggregate Option Price shall be paid in full to the Company by any of the methods or any combination of the methods set forth in subsection 6.2(g)(iv) below. 

(ii) The shares of Stock to which the Participant is entitled as a result of the exercise of the Option shall be issued by the Company and
either (A) delivered by electronic means to an account designated by the Participant or (B) delivered to the Participant in the form of a properly executed certificate or certificates representing such shares of Stock. If shares of Stock
are used to pay all or part of the aggregate Option Price, the Company shall issue and deliver to the Participant the additional shares of Stock, in excess of the aggregate Option Price or portion thereof paid using shares of Stock, to which the
Participant is entitled as a result of the Option exercise. 

  
 12 








 (iii) The Company’s obligation to deliver the shares of Stock to which the Participant is
entitled as a result of the exercise of the Option shall be subject to the payment in full to the Company of the aggregate Option Price and the required tax withholding. 

(iv) The aggregate Option Price shall be paid by any of the following methods or any combination of the following methods: 

 

	 	(A)	in cash, including the wire transfer of funds in U.S. dollars to one of the Company’s bank accounts located in the United States, with such bank account to be designated from time to time by the Company;


  

	 	(B)	by personal, certified or cashier’s check payable in U.S. dollars to the order of the Company; 

  

	 	(C)	by delivery to the Company or the Administrative Agent of certificates representing a number of shares of Stock then owned by the Participant, the aggregate Fair Market Value of which (as of the Exercise Date) is equal
to the aggregate Option Price of the Option being exercised, properly endorsed for transfer to the Company, provided that the shares of Stock used for this purpose must have been owned by the Participant for a period of at least six months;


  

	 	(D)	by certification or attestation to the Company or the Administrative Agent of the Participant’s ownership (as of the Exercise Date) of a number of shares of Stock, the aggregate Fair Market Value of which (as of
the Exercise Date) is not greater than the aggregate Option Price of the Option being exercised, provided that the shares of Stock used for this purpose have been owned by the Participant for a period of at least six months; or 


 

	 	(E)	by delivery to the Company or the Administrative Agent of a properly executed notice of exercise together with irrevocable instructions to a broker to promptly deliver to the Company, by wire transfer or check as noted
in subsection 6.2(g)(iv)(A) and (B) above, the amount of the proceeds of the sale of all or a portion of the Stock or of a loan from the broker to the Participant necessary to pay the aggregate Option Price. 


 

	 	(h)	Tax Withholding. Each Stock Option agreement shall provide that, upon exercise of the Option, the Participant shall make appropriate arrangements with the Company to provide for not less than the minimum
amount of tax withholding required by law, including without limitation Sections 3102 and 3402 or any successor section(s) of the Internal Revenue Code and applicable state and local income and other tax laws, by payment of such taxes in cash
(including wire transfer), by check, or as provided in Section 11 hereof. 

  

	 	(i)	 Repricing Prohibited. Subject to Sections 4, 6, 12, 13, and 16, outstanding Stock Options granted under this Plan shall not be repriced
without approval by the Company’s stockholders. In particular, neither the Board nor the Committee may take any action: (1) to amend the terms of an outstanding Option or SAR to reduce the Option Price or grant price thereof, cancel an
Option or SAR and replace it with a new Option or SAR with a lower Option Price or grant price, or take any other action (whether in the form of an amendment, cancellation or replacement grant, or a cash-out of underwater options) that has an
economic effect that is the same as any such reduction or cancellation or (2) to 



  
 13 








 
cancel an outstanding Option or SAR having an Option Price or grant price above the then-current Fair Market Value of the Stock in exchange for the grant of another type of Award, without, in
each such case, first obtaining approval of the stockholders of the Company of such action. 
  

	 	(j)	Stockholder Privileges. No Participant shall have any rights as a stockholder with respect to any shares of Stock covered by an Option until the Participant becomes the holder of record of such Stock.
Except as provided in Section 4 hereof, no adjustments shall be made for dividends or other distributions or other rights as to which there is a record date preceding the date on which such Participant becomes the holder of record of such
Stock. 

  

	 	(k)	Section 409A Avoidance. Once granted, no Stock Option shall be modified, extended, or renewed in any way that would cause the Stock Option to be subject to Internal Revenue Code Section 409A. The
Option Period shall not be extended to any date that would cause the Stock Option to become subject to Internal Revenue Code Section 409A. The Option Price shall not be adjusted to reflect any dividends declared and paid on the Stock between
the date of grant and the date the Stock Option is exercised. 

  

	 	(l)	Vesting Period. Each Stock Option agreement shall state the vesting period (the period which ends as of a date that the Option is no longer restricted or subject to forfeiture) that applies to the
specified number of shares of Stock granted pursuant thereto. In respect of the employees of the Company (including executive officers), such vesting period for the entire Option award shall in no event be less than three years following the grant
date, and, subject to Sections 12 and 13 of the Plan, the Committee may not waive such minimum vesting period except in the case of the Participant’s death or disability. 


Section 7 
 7.1 Stock Appreciation
Rights. The Committee (or, if so provided pursuant to Section 3.4(b), the Chief Executive Officer of the Company) is authorized to grant SARs to Participants either alone (“freestanding”) or in tandem with other Awards,
including Performance Awards, Options, and Restricted Stock. Stock Appreciation Rights granted in tandem with any Award must be granted at the same time as the Award is granted. Stock Appreciation Rights granted in tandem with Options shall
terminate and no longer be exercisable upon the termination or exercise of the related Stock Options. Options granted in tandem with Stock Appreciation Rights shall terminate and no longer be exercisable upon the termination or exercise of the
related Stock Appreciation Rights. The Committee shall establish the terms and conditions applicable to any Stock Appreciation Rights, which terms and conditions need not be uniform but may not be inconsistent with the terms of the Plan.
Freestanding Stock Appreciation Rights shall generally be subject to terms and conditions substantially similar to those described in Section 4 and subsection 6.2 for Options, including, but not limited to, the requirements of subsections
6.2(b), (d), (i) and (l) and subsection 4.7 regarding general adjustment rules, minimum price, duration, and prohibition on repricing. 
 7.2
Section 409A Avoidance. The SAR Price may be fixed on the date it is granted or the SAR Price may vary according to an objective formula specified by the Committee at the time of grant. However, the SAR Price can never be less
than the Fair Market Value of the Stock on the date of grant. The SAR grant must specify the number of shares to which it applies, which must be fixed at the date of grant 

  
 14 








 
(subject to adjustment pursuant to Sections 4, 6, and 11). Once granted, no SAR shall be modified, extended, or renewed in any way that would cause the SAR to be subject to Internal Revenue Code
Section 409A. The period during which the SAR may be exercised shall not be extended to any date that would cause the SAR to become subject to Internal Revenue Code Section 409A. The value of the SAR shall not be adjusted to reflect any
dividends declared and paid on the Stock between the date of grant and the date the SAR is exercised; however, the right to one or more dividends declared and paid on the Stock between the date of grant and the date the SAR is exercised may be set
forth in a separate arrangement. 
 Section 8 

Restricted Stock and Restricted Stock Units 
 8.1
Restriction Period. At the time an Award of Restricted Stock or Restricted Stock Units is made, the Committee shall establish the terms and conditions applicable to such Award, including the period of time (the “Restriction
Period”) and attainment of performance goals during which certain restrictions established by the Committee shall apply to the Award. Awards of Restricted Stock or Restricted Stock Units may also be made in accordance with Section 3.4(b).
In respect of the employees of the Company (including executive officers), such Restriction Period, the time ending as of the date upon which the entire Award of Restricted Stock or Restricted Stock Units is no longer restricted or subject to
forfeiture provisions, shall in no event be less than three years following the initial grant date of the Award of Restricted Stock or Restricted Stock Units (such Restriction Period to include periods of time during which the achievement of
specific performance goals or other performance is measured with respect to such Awards), and, subject to Sections 12 and 13 of the Plan, the Committee may not waive such minimum Restriction Period except in the case of the Participant’s death
or disability. Each such Award, and designated portions of the same Award, may have a different Restriction Period. Except as permitted or pursuant to Sections 12 and 13 hereof, the Restriction Period applicable to a particular Award shall not be
changed. Restricted Stock or Restricted Stock Units may or may not be subject to Internal Revenue Code Section 409A. If they are subject to Internal Revenue Code Section 409A, the grant of the Restricted Stock or Restricted Stock Units
must contain the provisions needed to comply with the requirements of Internal Revenue Code Section 409A, including but not limited to (i) the timing of any election to defer receipt of the Restricted Stock or Restricted Stock Units beyond
the date of vesting, (ii) the timing of any payout election, and (iii) the timing of the settlement of Restricted Stock or a Restricted Stock Unit. Restricted Stock or Restricted Stock Units that are subject to Internal Revenue Code
Section 409A may be adjusted to reflect any dividends declared and paid on the Stock between the date of grant and the date the Restricted Stock or Restricted Stock Unit vests, but only to the extent permitted in IRS guidance of general
applicability. 
 8.2 Certificates for Stock. Restricted Stock shall be evidenced in such manner as the Committee shall determine. If
certificates representing Restricted Stock are registered in the name of the Participant, the Committee may require that such certificates bear an appropriate legend referring to the terms, conditions, and restrictions applicable to such Restricted
Stock, that the Company retain physical possession of the certificates, and that the Participant deliver a stock power to the Company, endorsed in blank, relating to the Restricted Stock represented by a stock certificate registered in the name of
the Participant. 
 8.3 Restricted Stock Terms and Conditions. Participants shall have the right to enjoy all shareholder rights during the
Restriction Period except that: 
  

	 	(a)	The Participant shall not be entitled to delivery of the Stock certificate until the Restriction Period shall have expired. 


  
 15 









	 	(b)	The Participant may not sell, transfer, pledge, exchange, hypothecate, or otherwise dispose of the Stock during the Restriction Period. 


 

	 	(c)	A breach of the terms and conditions established by the Committee with respect to the Restricted Stock shall cause a forfeiture of the Restricted Stock and any dividends withheld thereon. 


 

	 	(d)	Dividends and Splits. As a condition to the grant of an Award of Restricted Stock, the Committee may specify whether any cash dividends paid on a share of Restricted Stock be automatically reinvested in additional
shares of Restricted Stock or applied to the purchase of additional Awards under this Plan. Unless otherwise determined by the Committee, Stock distributed in connection with a Stock split or Stock dividend, and other property distributed as a
dividend, shall be subject to restrictions and a risk of forfeiture to the same extent as the Restricted Stock with respect to which such Stock or other property has been distributed. 


8.4 Restricted Stock Units. The Committee (or, if so provided pursuant to Section 3.4(b), the Chief Executive Officer of the Company) is
authorized to grant Restricted Stock Units to Participants, which are rights to receive Stock at the end of a specified deferral period, subject to the following terms and conditions: 

Award and Restrictions. Settlement of an Award of Restricted Stock Units shall occur upon expiration of the vesting period specified for
such Restricted Stock Unit by the Committee (or, if permitted by the Committee, as elected by the Participant pursuant to Section 8.5). In addition, Restricted Stock Units shall be subject to such restrictions (which may include a risk of
forfeiture) as the Committee may impose, if any, which restrictions may lapse at the expiration of the vesting or deferral period, as the case may be, or at earlier specified times (including based on achievement of performance goals and/or future
service requirements), separately or in combination, in installments or otherwise, as the Committee may determine. Restricted Stock Units shall be satisfied by the delivery of cash or Stock in the amount equal to the Fair Market Value of the
specified number of shares of Stock covered by the Restricted Stock Units, or a combination thereof, as determined by the Committee at the date of grant or thereafter. 

8.5 Deferral of Receipt of Restricted Stock Units. With the consent of the Committee, a Participant who has been granted a Restricted Stock Unit
may by compliance with the then applicable procedures under the Plan irrevocably elect in writing to defer receipt of all or any part of any distribution associated with that Restricted Stock Unit Award in accordance with either the terms and
conditions of the Deferred Delivery Plan or the terms and conditions specified under the grant agreement and related documents. The terms and conditions of any such deferral, including, but not limited to, the period of time for, and form of,
election; the manner and method of payout; and the use and form of Dividend Equivalents in respect of stock-based units resulting from such deferral, shall be as determined by the Committee. The Committee may, at any time and from time to time, but
prospectively only except as hereinafter provided, amend, modify, change, suspend, or cancel any and all of the rights, procedures, mechanics, and timing parameters relating to such deferrals. In addition, the Committee may, in its sole discretion,
accelerate the pay out of such deferrals (and any earnings thereon), or any portion thereof, either in a lump sum or in a series of payments, but only to the extent that the payment or the change in timing of the payment will not cause a violation
of Internal Revenue Code Section 409A. 

  
 16 








 8.6 Bonus Stock and Awards in Lieu of Obligations. The Committee is authorized to grant Stock as a
bonus, or to grant Stock or other Awards in lieu of obligations to pay cash or deliver other property under this Plan or under plans or compensatory arrangements, provided that, in the case of Participants subject to Section 16 of the Exchange
Act, the amount of such grants remains within the discretion of the Committee to the extent necessary to ensure that acquisitions of Stock or other Awards are exempt from liability under Section 16(b) of the Exchange Act. Stock or Awards
granted hereunder shall be subject to such other terms as shall be determined by the Committee. In the case of any grant of Stock to an officer of the Company or an Affiliate in lieu of salary or other cash compensation, the number of shares granted
in place of such compensation shall be reasonable, as determined by the Committee. 
 8.7 Dividend Equivalents. The Committee is authorized to
grant Dividend Equivalents to a Participant, entitling the Participant to receive cash, Stock, other Awards, or other property equal in value to dividends paid with respect to a specified number of shares of Stock, or other periodic payments.
Dividend Equivalents may be awarded on a free-standing basis or in connection with another Award. The Committee may provide that Dividend Equivalents shall be paid or distributed when accrued or shall be deemed to have been reinvested in additional
Stock, Awards, or other investment vehicles, and subject to risk of forfeiture, as the Committee may specify. Notwithstanding the foregoing, Dividend Equivalents shall not be granted in connection with the grant of any Options or Stock Appreciation
Right. 
 Section 9 

Performance Awards 
 9.1 Establishment of
Performance Goals for Company. Performance Goals applicable to a Performance Award shall be established by the Committee in its absolute discretion on or before the date of grant and within the time period prescribed by, and shall otherwise
comply with the requirements of, Code Section 162(m)(4)(C), or any successor provision thereto, and the regulations thereunder, for performance-based compensation. Such Performance Goals may include or be based upon any of the following
criteria, either in absolute amount, per share, or per barrel of oil equivalent (boe): pretax income or after tax income, operating profit, return on equity, capital or investment, earnings, book value, increase in cash flow return, sales or
revenues, operating expenses (including, but not limited to, lease operating expenses, severance taxes and other production taxes, gathering and transportation, general and administrative costs, and other components of operating expenses), stock
price appreciation, implementation or completion of critical projects or processes, production growth, reserve growth, and/or corporate acquisition goals based on value of assets acquired or similar objective measures. 

Where applicable, the Performance Goals may be expressed in terms of attaining a specified level of a particular criteria or attaining a percentage increase
or decrease in a particular criteria, and may be applied relative to internal goals or levels attained in prior years or related to other companies or indices or as ratios expressing relationship between Performance Goals, or any combination
thereof, as determined by the Committee. 

  
 17 








 The Performance Goals may include a threshold level of performance below which no vesting will occur, levels of
performance at which specified vesting will occur, and a maximum level of performance at which full vesting will occur. 
 The Committee may in its
discretion classify Participants into as many groups as it determines, and as to any Participant relate his/her Performance Goals partially, or entirely, to the measured performance, either absolutely or relatively, of an identified subsidiary,
division, operating company, test strategy, or new venture of the Company and/or its Affiliates. 
 Notwithstanding any other provision of the Plan, payment
or vesting of any Performance Award shall not be made until the applicable Performance Goals have been satisfied and any other material terms of such Award were in fact satisfied. The Committee shall certify in writing the attainment of each
Performance Goal. Notwithstanding any provision of the Plan to the contrary, with respect to any Performance Award, (a) the Committee may not adjust, downwards or upwards, any amount payable, or other benefits granted, issued, retained, and/or
vested pursuant to such an Award on account of satisfaction of the applicable Performance Goals and (b) the Committee may not waive the achievement of the applicable Performance Goals, except in the case of the Participant’s death or
disability, or a Change of Control. 
 9.2 Levels of Performance Required to Earn Performance Awards. At or about the same time that
Performance Goals are established for a specific period, the Committee shall in its absolute discretion establish the percentage of the Performance Awards granted for such Performance Period which shall be earned by the Participant for various
levels of performance measured in relation to achievement of Performance Goals for such Performance Period. 
 9.3 Other Restrictions. The
Committee shall determine the terms and conditions applicable to any Performance Award, which may include restrictions on the delivery of Stock payable in connection with the Performance Award and restrictions that could result in the future
forfeiture of all or part of any Stock earned. The Committee may provide that shares of Stock issued in connection with a Performance Award be held in escrow and/or legended. Performance Awards may or may not be subject to Internal Revenue Code
Section 409A. If a Performance Award is subject to Internal Revenue Code Section 409A, the Performance Award grant agreement shall contain the terms and conditions needed to comply with the requirements of Internal Revenue Code
Section 409A, including but not limited to (i) the timing of any election to defer receipt of the Performance Award, (ii) the timing of any payout election, and (iii) the timing of the actual payment of the Performance Award.
Performance Awards that are subject to Internal Revenue Code Section 409A may be adjusted to reflect any dividends declared and paid on the Stock between the date of grant and the date the Performance Award is paid, but only to the extent
permitted in IRS guidance of general applicability. 
 9.4 Notification to Participants. Promptly after the Committee has established the
Performance Goals with respect to a Performance Award, the Participant shall be provided with written notice of the Performance Goals so established. 
 9.5
Measurement of Performance against Performance Goals. The Committee shall, as soon as practicable after the close of a Performance Period, determine (a) the extent to which the Performance Goals for such Performance Period have
been achieved and (b) the percentage of the Performance Awards earned as a result. 

  
 18 








 These determinations shall be absolute and final as to the facts and conclusions therein made and be binding on
all parties. Promptly after the Committee has made the foregoing determination, each Participant who has earned Performance Awards shall be notified. For all purposes of this Plan, notice shall be deemed to have been given the date action is taken
by the Committee making the determination. Participants may not sell, transfer, pledge, exchange, hypothecate, or otherwise dispose of all or any portion of their Performance Awards during the Performance Period. 

9.6 Treatment of Performance Awards Earned. Upon the Committee’s determination that a percentage of any Performance Award has been earned
for a Performance Period, Participants to whom such earned Performance Awards have been granted and who have been in the employ of the Company or Affiliates continuously from the date of grant until the end of the Performance Period, subject to the
exceptions set forth in the Performance Award agreement and in Sections 10 and 12 hereof, shall be entitled, subject to the other conditions of this Plan, to payment in accordance with the terms and conditions of the Performance Awards. Performance
Awards shall under no circumstances become earned or have any value whatsoever for any Participant who is not in the employ of the Company or its Affiliates continuously during the entire Performance Period for which such Performance Award was
granted, except as provided in Sections 10 and 12. 
 9.7 Subsequent Performance Award Grants. Following the grant of Performance Awards with
respect to a Performance Period, additional Participants may be designated by the Committee for grant of Performance Awards for such Performance Period subject to the same terms and conditions set forth for the initial grants, except that the
Committee, in its sole discretion, may reduce the value of the amounts to which subsequent Participants may become entitled, prorated according to reduced time spent during the Performance Period, and the applicable Performance Award agreement shall
be modified to reflect such reduction. 
 9.8 Stockholder Privileges. No Participant shall have any rights as a stockholder with respect to
any shares of Stock covered by a Performance Award until the Participant becomes the holder of record of such Stock. 
 Section 10 

Termination of Employment, Death, Disability, etc. 

10.1 Termination of Employment. Except as provided herein, the treatment of an Award upon a termination of employment or any other service
relationship by and between a Participant and the Company or an Affiliate shall be specified in the agreement controlling such Award. To the extent such Award is subject to Section 409A of the Code, such termination of employment or any other
service relationship shall be a “separation from service” within the meaning of Treasury Regulation Section 1.409A-1(h) with respect to any Award intended to comply with Section 409A of the Internal Revenue Code; provided, that a
“separation from service” shall occur only if both the Company and the Participant expect the Participant’s level of services to permanently drop by more than half. 

10.2 Termination for Cause. If the employment of the Participant by the Company is terminated for cause, as determined by the Committee, all
Awards to such Participant shall thereafter be void for all purposes. As used in subsections 9.1, 10.2, and 10.3 hereof, “cause” shall mean a gross violation, as determined by the Committee, of the Company’s established policies and
procedures, provided that the effect of this subsection 10.2 shall be limited to determining the consequences of a termination and 
 that nothing in this
subsection 10.2 shall restrict or otherwise interfere with the Company’s discretion with respect to the termination of any employee. 

  
 19 








 10.3 Performance Awards. Except as set forth below, each Performance Award shall state that each
such Award shall be subject to the condition that the Participant has remained an Eligible Person from the date of grant until the applicable vesting date as follows: 
  

	 	(a)	If the Participant voluntarily leaves the employment of the Company or an Affiliates, or if the employment of the Participant is terminated by the Company for cause or otherwise, any Performance Award to such
Participant not previously vested shall thereafter be void and forfeited for all purposes. 

  

	 	(b)	A Participant shall become vested in all Performance Awards that have met the Performance Goals within the Performance Period on the date the Participant retires from employment with the Company on or after attaining
retirement age (which for all purposes of this Plan is determined to be age 65, unless otherwise designated by the Committee at the time the Award is granted), on the date the Participant dies while employed by the Company, or on the date the
Participant terminates service with the Company and the Affiliates due to permanent disability (as determined pursuant to the Company’s Long-Term Disability Plan or any successor plan, unless the Performance award is subject to Internal Revenue
Code Section 409A, in which case “permanent disability” must also fall within the meaning specified in Internal Revenue Code Section 409A(a)(2)(C) or a more restrictive meaning established by the Committee) while employed by the
Company. Such Participant shall not become entitled to any payment which may arise due to the occurrence of a Performance Goal after the Participant dies, terminates service due to permanent disability, or retires. Payment shall occur as soon as
administratively convenient following the date the Participant dies, terminates service due to permanent disability, or retires, but in no event shall the payment occur later than March 15 in the calendar year immediately following the calendar
year in which the Participant died, so terminates service, or retired. If the Participant dies before receiving payment, the payment shall be made to those entitled pursuant to Section 14.2 of this Plan. 


10.4 Forfeiture Provisions. Subject to Sections 12 and 14, in the event a Participant terminates employment during a Restriction Period for the
Participant’s Restricted Stock or Restricted Stock Units, such Awards will be forfeited; provided, however, that the Committee may provide for proration or full payout in the event of (a) death, (b) permanent disability, or
(c) any other circumstances the Committee may determine. 
 Section 11 

Tax Withholding 
 11.1 Withholding
Requirement. The Company and any Affiliate is authorized to withhold from any Award granted, or any payment relating to an Award under this Plan, including from a distribution of Stock, amounts of withholding and other taxes or social
security payments due or potentially payable in connection with any transaction involving an Award, and to take such other action as the Committee may deem advisable to enable the Company and Participants to satisfy obligations for the payment of
withholding taxes and other tax or social security obligations relating to any Award. This authority shall 

  
 20 








 
include authority to withhold or receive Stock or other property and to make cash payments in respect thereof, in satisfaction of a Participant’s tax obligations, either on a mandatory or
elective basis at the discretion of the Committee. 
 11.2 Withholding Requirement – Stock Options and SARs. The Company’s
obligations to deliver shares of Stock upon the exercise of an Option or SAR shall be subject to the Participant’s satisfaction of all applicable federal, state, and local income and other tax and social security withholding requirements. 

At the time the Committee grants an Option, it may, in its sole discretion, grant the Participant an election to pay all such amounts of required tax
withholding, or any part thereof: 
  

	 	(a)	by the delivery to the Company or the Administrative Agent of a number of shares of Stock then owned by the Participant, the aggregate Fair Market Value of which (as of the Exercise Date) is not greater than the amount
required to be withheld, provided that such shares have been held by the Participant for a period of at least six months; 

  

	 	(b)	by certification or attestation to the Company or the Administrative Agent of the Participant’s ownership (as of the Exercise Date) of a number of shares of Stock, the aggregate Fair Market Value of which (as of
the Exercise Date) is not greater than the amount required to be withheld, provided that such shares of Stock have been owned by the Participant for a period of at least six months; or 


 

	 	(c)	by the Company or the Administrative Agent withholding from the shares of Stock otherwise issuable to the Participant upon exercise of the Option, a number of shares of Stock, the aggregate Fair Market Value of which
(as of the Exercise Date) is not greater than the amount required to be withheld. Any such elections by Participants to have shares of Stock withheld for this purpose will be subject to the following restrictions: 


 

	 	(i)	all elections shall be made on or prior to the Exercise Date; and 

  

	 	(ii)	all elections shall be irrevocable. 

 11.3 Section 16 Requirements. If the Participant is an
officer or director of the Company within the meaning of Section 16 or any successor section(s) of the Exchange Act (“Section 16”), the Participant must satisfy the requirements of Section 16 and any applicable rules and
regulations thereunder with respect to the use of shares of Stock to satisfy such tax withholding obligation. 
 11.4 Restricted Stock and Performance
Award Payment and Tax Withholding. Each Restricted Stock and Performance Award agreement shall provide that, upon payment of any entitlement under such an Award, the Participant shall make appropriate arrangements with the Company to provide
for the amount of minimum tax and social security withholding required by law, including without limitation Sections 3102 and 3402 or any successor section(s) of the Internal Revenue Code and applicable state and local income and other tax and
social security laws. The withholding may be deducted from the Award. Any payment under such an Award shall be made in a proportion of cash and shares of Stock, determined by the Committee, such that the cash portion shall be sufficient to cover the
withholding amount required by this Section. The cash portion of any payment shall be based on the Fair Market Value of the shares of Stock on the applicable date of vesting to which such tax withholding relates. Such cash portion shall be withheld
by the Company to satisfy applicable tax and social security withholding requirements.

 Section 12 

Change of Control 
 12.1 In
General. In the event of the occurrence of a Change of Control of the Company: 
  

	 	(a)	Without further action by the Committee or the Board, 

 all outstanding Options shall fully vest upon the
Participant’s Involuntary Termination or Voluntary Termination with Cause occurring on or after a Change of Control. Such newly vested Options shall be fully exercisable as of the date of the Involuntary Termination or Voluntary Termination
with Cause on or after a Change of Control occurs. 
  

	 	(b)	Without further action by the Committee or the Board, 

 all unvested Restricted Stock Awards and Restricted
Stock Units shall fully vest upon the Participant’s Involuntary Termination or Voluntary Termination with Cause occurring on or after a Change of Control. Such newly vested Restricted Stock Units shall be converted to Stock and the Participant
shall be issued the requisite number of shares, after any withholding under Section 11, as soon as administratively practicable after the Involuntary Termination or Voluntary Termination with Cause on or after a Change of Control occurs, unless
the Participant had elected to defer Restricted Stock Units to the Deferred Delivery Plan in which case the Participant’s account in the Deferred Delivery Plan shall be credited with deferred Restricted Stock Units as of the date of the
Involuntary Termination or Voluntary Termination with Cause on or after the Change of Control occurs. 
  

	 	(c)	Assuming the achievement of a Performance Goal, the entitlement to receive cash and Stock under any outstanding Performance Award grants shall vest automatically, without further action by the Committee or the Board,
and shall become payable as follows: 

  

	 	(i)	If such Change of Control occurs subsequent to the achievement of a Performance Goal, any remainder of such payout amount shall vest as of the date of the Participant’s Involuntary Termination or Voluntary
Termination with Cause occurring on or after the date of such Change of Control and shall be paid by the Company to the Participant within thirty (30) days of the date of such Involuntary Termination or Voluntary Termination with Cause which
occurs on or after the date of the Change of Control in the manner set out in subsection 12.1 hereof. 

  

	 	(ii)	If the achievement of a Performance Goal occurs subsequent to the date of a Change of Control, the applicable payout amount shall vest in full for which the Performance Period has not yet ended as of the date of the
Participant’s Involuntary Termination or Voluntary Termination with Cause occurring on or after such Change of Control and shall be paid by the Company to the Participant within thirty (30) days after the later of (1) the date of the
Participant’s Involuntary Termination or Voluntary Termination with Cause or (2) the date that the Performance Goal is reached. The payment will occur only if the Participant is employed at the time that the Performance Goal is



  
 22 









	 	
reached or if the Performance Goal is reached after the Participant’s Involuntary Termination or Voluntary Termination with Cause occurring on or after the Change of Control.


  

	 	(d)	To the extent that any Award is subject to Internal Revenue Code Section 409A, the Award shall contain appropriate provisions to comply with Internal Revenue Code Section 409A, which shall supersede the
provisions of subsections (a), (b), and (c). 

 Section 13 

Reorganization or Liquidation 
 In the event that
the Company is merged or consolidated with another corporation and the Company is not the surviving corporation, or if all or substantially all of the assets or more than 20 percent of the outstanding voting stock of the Company is acquired by any
other corporation, business entity or person, or in case of a reorganization (other than a reorganization under the United States Bankruptcy Code) or liquidation of the Company, then the Committee, or the board of directors of any corporation
assuming the obligations of the Company, shall, as to the Plan and outstanding Awards make appropriate provision for the adoption and continuation of the Plan by the acquiring or successor corporation and for the protection of any holders of such
outstanding Awards by the substitution on an equitable basis of appropriate stock of the Company or of the merged, consolidated, or otherwise reorganized corporation which will be issuable with respect to the Stock. Additionally, upon the occurrence
of such an event and provided that a Performance Goal has occurred, upon written notice to the Participants, the Committee may accelerate the vesting and payment dates of the entitlement to receive cash and Stock under outstanding Awards so that all
such existing entitlements are paid prior to any such event. If a Performance Goal has not yet been attained, the Committee in its discretion may make equitable payment or adjustment. 

In its discretion, and on such terms and conditions as it deems appropriate, the Committee may provide, either by the terms of an agreement applicable to any
Award or by resolution adopted prior to the occurrence of a Change of Control or an event described in this Section 13, that any outstanding Award (or portion thereof) shall be converted into a right to receive cash, on or as soon as
practicable following the closing date or expiration date of the transaction resulting in the Change of Control or such event in an amount equal to the highest value of the consideration to be received in connection with such transaction for one
share of Stock, or, if higher, the highest Fair Market Value of a share of Stock during the thirty (30) consecutive business days immediately prior to the closing date or expiration date of such transaction, less the per-share Option Price or
grant price of SARs, as applicable to the Award, multiplied by the number of shares subject to such Award, or the applicable portion thereof. 

Section 14 
 Rights of
Employees and Participants 
 14.1 Employment. Neither anything contained in the Plan or any agreement nor the granting of any Award under the
Plan shall confer upon any Participant any right with respect to the continuation of his or her employment by the Company or any Affiliate, or interfere in any way with the right of the Company or any Affiliate, at any time, to terminate such
employment or to increase or decrease the level of the Participant’s compensation from the level in existence at the time of the Award. 

  
 23 








 An Eligible Person who has been granted an Award in one year shall not necessarily be entitled to be granted
Awards in subsequent years. 
 14.2 Non-transferability. Except as otherwise determined at any time by the Committee as to any Awards other
than ISOs, no right or interest of any Participant in an Award granted pursuant to the Plan shall be assignable or transferable during the lifetime of the Participant, either voluntarily or involuntarily, or subjected to any lien, directly or
indirectly, by operation of law, or otherwise, including execution, levy, garnishment, attachment, pledge, bankruptcy, or court order; provided that the Committee may permit further transferability of Awards other than ISOs, on a general or a
specific basis, and may impose conditions and limitations on any permitted transferability, subject to any applicable Restriction Period; provided further, however, that no Award may be transferred for value or other
consideration without first obtaining approval thereof by the stockholders of the Company. In the event of a Participant’s death, a Participant’s rights and interests in any Award as set forth in an Award agreement, shall be transferable
by testamentary will or the laws of descent and distribution, or, with respect to Awards other than Incentive Stock Options, a beneficiary designation that is in a form approved by the Committee and in compliance with the provisions of this Plan,
applicable law, and the applicable Award agreement, and payment of any entitlements due under the Plan shall be made to the Participant’s designated beneficiary, legal representatives, heirs, or legatees, as applicable. If in the opinion of the
Committee a person entitled to payments or to exercise rights with respect to the Plan is disabled from caring for his or her affairs because of mental condition, physical condition, or age, payment due such person may be made to, and such rights
shall be exercised by, such person’s guardian, conservator, or other legal personal representative upon furnishing the Committee with evidence satisfactory to the Committee of such status. If any individual entitled to payment or to exercise
rights with respect to the Plan is a minor, the Committee shall cause the payment to be made to (or the right to be exercised by) the custodian or representative who, under the state law of the minor’s domicile, is authorized to act on behalf
of the minor or is authorized to receive funds on behalf of the minor. With respect to those Awards, if any, that are permitted to be transferred to another individual, references in the Plan to exercise or payment related to such Awards by or to
the Participant shall be deemed to include, as determined by the Committee, the Participant’s permitted transferee. A Participant’s unexercised Option or SAR, or amounts due but remaining unpaid to such Participant, at the
Participant’s death, shall be exercised or paid as designated by the Participant by will or by the laws of descent and distribution, or, with respect to any unexercised Option or SAR other than an Incentive Stock Option, in accordance with the
Participant’s beneficiary designation in a form approved by the Committee and in compliance with the provisions of this Plan, applicable law and the applicable Award agreement. In the event any Award is exercised by or otherwise paid to the
executors, administrators, heirs or distributees of the estate of a deceased Participant, or the transferee or designated beneficiary of an Award, in any such case, pursuant to the terms and conditions of the Plan and the applicable Award agreement
and in accordance with such terms and conditions as may be specified from time to time by the Committee, the Company shall be under no obligation to issue shares of Stock thereunder unless and until the Company is satisfied, as determined in the
discretion of the Committee, that the person or persons exercising such Award, or to receive such payment, are the duly appointed legal representative of the deceased Participant’s estate or the proper legatees or distributees thereof, or the
valid transferee or designated beneficiary of such Award, as applicable. Any purported assignment, transfer or encumbrance of an Award that does not comply with this Section 14.2 shall be void and unenforceable against the Company. 

  
 24 








 14.3 Noncompliance with Internal Revenue Code Section 409A. If an Award is subject to the
requirements of Internal Revenue Code Section 409A, to the extent that the Company or an Affiliate takes any action that causes a violation of Internal Revenue Code Section 409A or fails to take reasonable actions required to comply with
Internal Revenue Code Section 409A, in each case as determined by the Committee, the Company shall pay an additional amount to the Participant (or beneficiary) equal to the additional income tax imposed pursuant to Internal Revenue Code
Section 409A on the Participant as a result of such violation, plus any taxes imposed on this additional payment. 
 Section 15

 Other Employee Benefits 
 The amount of any
income deemed to be received by a Participant as a result of the payment under an Award or exercise shall not constitute “earnings” or “compensation” with respect to which any other employee benefits of such Participant are
determined, including without limitation benefits under any pension, profit sharing, life insurance, or salary continuation plan. 

Section 16 
 Amendment,
Modification, and Termination 
 The Committee or the Board may at any time terminate, and from time to time may amend or modify the Plan, and the Committee
or the Board may, to the extent permitted by the Plan, from time to time amend or modify the terms of any Award theretofore granted, including any Award agreement, in each case, retroactively or prospectively; provided, however, that
no amendment or modification of the Plan may become effective without approval of the amendment or modification by the Company’s stockholders if stockholder approval is required to enable the Plan to satisfy an applicable statutory or
regulatory requirements, unless the Company, on the advice of outside counsel, determines that stockholder approval is not necessary. 
 Notwithstanding any
other provision of this Plan, no amendment, modification, or termination of the Plan or any Award shall adversely affect the previously accrued material rights or benefits of a Participant under any outstanding Award theretofore awarded under the
Plan, without the consent of such Participant holding such Award, except to the extent necessary to avoid a violation of Internal Revenue Code Section 409A or the Board or the Committee determines, on advice of outside counsel or the
Company’s independent accountants, that such amendment or modification is required for the Company, the Plan, or the Award to satisfy, comply with, or meet the requirements of any law, regulation, listing rule, or accounting standard applicable
to the Company. 
 The Committee shall have the authority to adopt (without the necessity for further stockholder approval) such modifications, procedures,
and subplans as may be necessary or desirable to comply with the provisions of the laws (including, but not limited to, tax laws and regulations) of countries other than the United States in which the Company may operate, so as to assure the
viability of the benefits of the Plan to Participants employed in such countries.

 Section 17 

Requirements of Law 
 17.1 Requirements of
Law. The issuance of Stock and the payment of cash pursuant to the Plan shall be subject to all applicable laws, rules, and regulations, including applicable federal and state securities laws. The Company may require a Participant, as a
condition of receiving payment under an Award, to give written assurances in substance and form satisfactory to the Company and its counsel to such effect as the Company deems necessary or appropriate in order to comply with federal and applicable
state securities laws. 
 17.2 Section 409A of the Code. It is intended that this Plan shall comply with the provisions of, or an
exemption from, Internal Revenue Code Section 409A and the Treasury regulations relating thereto. Awards are intended to be exempt from Internal Revenue Code Section 409A to the extent possible. Any Award or payment that qualifies for an
exemption shall be considered as the first payment(s) made under the Plan. For purposes of the limitations on nonqualified deferred compensation under Internal Revenue Code Section 409A, each payment of compensation under this Plan shall be
treated as a separate payment of compensation for purposes of applying the deferral election rules and the exemption for certain short-term deferral amounts under Internal Revenue Code Section 409A. In no event may the Participant, directly or
indirectly, designate the calendar year of any payment subject to Internal Revenue Code Section 409A under this Plan. 
 Six-month Delay for
Specified Participants. Notwithstanding any other provision of this Plan, to the extent that the right to any payment (including the provision of benefits) hereunder provides for the “deferral of compensation” within the meaning of
Internal Revenue Code Section 409A(d)(1), the payment shall be paid (or provided) in accordance with the following: If the Participant is a “Specified Employee” within the meaning of Internal Revenue Code Section 409A(a)(2)(B)(i)
on the date of the Participant’s Separation from Service (the “Separation Date”), and if an exemption from the six (6) month delay requirement of Internal Revenue Code Section 409A(a)(2)(B)(i) is not available, then
no such payment shall be made or commence during the period beginning on the Separation Date and ending on the date that is six months following the Separation Date or, if earlier, on the date of the Participant’s death. The amount of any
payment that would otherwise be paid to the Participant during this period shall instead be paid to the Participant on the first day of the first calendar month following the end of the period. 

Prohibition on Acceleration. Unless a payment is exempt from Internal Revenue Code Section 409A, the date of payment may not be
accelerated and any payment made pursuant to the termination and liquidation of the Plan shall not be accelerated except in compliance with Internal Revenue Code Section 409A generally and Treasury Regulation § 1.409A-3(j)(4)(ix)
specifically. 
 17.3 Section 16 Requirements. If a Participant is an officer or director of the Company within the meaning of
Section 16 of the Exchange Act, Awards granted hereunder shall be subject to all conditions required under Rule 16b-3, or any successor rule(s) promulgated under the Exchange Act, to qualify the Award for any exemption from the provisions of
Section 16 available under such Rule. Such conditions are hereby incorporated herein by reference and shall be set forth in the agreement with the Participant, which describes the Award. 

17.4 Governing Law. The Plan and all agreements hereunder shall be construed in accordance with and governed by the laws of the State of Texas.
