eligible employees the opportunity to purchase Common Stock at a discount on a basis that qualifies for the tax treatment prescribed by Section 423 of the Code. 
  

	2.	Definitions 

 The following terms, when used in the
Plan, shall have the following meanings: 
  

	 	(a)	Base Compensation means, with respect to any offering period: (i) in the case of an employee normally paid an hourly rate, the employee’s hourly rate at the inception of
the offering period multiplied by 2,080, (ii) in the case of an employee normally paid at a weekly rate, the employee’s weekly rate at the inception of the offering period multiplied by 52, (iii) in the case of an employee normally

offering period multiplied by 12; and (v) in the case of an employee normally paid at an annual rate, the employee’s annual rate at the inception of the offering period. Base compensation shall be determined by reference to the applicable
rate before any deductions pursuant to a salary reduction agreement under any plan qualified under Section 401(k) of the Code or any cafeteria plan under Code Section 125 and shall exclude any bonuses, commissions, overtime pay, fringe
benefits, stock options and other special compensation payable to an employee.

Street Journal or another reputable source designated by the Committee; provided that if there were no sales on such date reported as provided above, the respective prices on the most recent prior day for which a sale was so reported. If the
foregoing method of determining fair market value should be inconsistent with Section 423 of the Code, “Fair Market Value” shall be determined by the Committee in a manner consistent with such section of the Code and shall mean the
value as so determined.

	 	(ii)	make all other determinations necessary or advisable for the administration of the Plan, including but not limited to interpreting the Plan, correcting defects, reconciling
inconsistencies and resolving ambiguities. 

  

	 	(iii)	approve any transaction involving a grant, award or other transaction from the Company to a Section 16 Person (other than a Discretionary Transaction, as defined in SEC Rule
16b-3), so as to exempt such transaction under SEC Rule 16b-3; provided, that any transaction under the Plan involving a Section 16 Person also may be approved by the Board of Directors, or may be approved or ratified by the stockholders of the

	4.	Stock Subject to the Plan 

  

	 	(a)	Subject to paragraph (c) below, the aggregate number of shares of Common Stock which may be sold under the Plan is 4,800,000. 

  

	 	(b)	If the number of shares of Common Stock that participating employees become entitled to purchase is greater than the number of shares of Common Stock that are offered in a
particular offering or that remain available under the Plan, the available shares of Common Stock shall be allocated by the Committee among such participating employees in such manner as it deems fair and equitable. 

  

	 	(c)	In the event of any change in the Common Stock, through recapitalization, merger, consolidation, stock dividend or split, combination or exchange of shares, spinoff or otherwise,
the Committee may make such equitable adjustments in the Plan and the then outstanding offerings as it deems necessary and appropriate including, but not limited to, changing the number of shares of Common Stock reserved under the Plan, and the
price of the current offering; provided that any such adjustments shall be consistent with Sections 423 and 424 of the Code. 

  

	 	(d)	Shares of Common Stock which are to be delivered under the Plan may be obtained by the Company from its treasury, by purchases on the open market or from private sources, or by
issuing authorized but unissued shares of its Common Stock. Shares of authorized but unissued Common Stock may not be delivered under the Plan if the purchase price thereof is less than the par value (if any) of the Common Stock at the time. The
Committee may (but need not) provide at any time or from time to time (including without limitation upon or in contemplation of a change in control) for a number of shares of Common Stock equal in number to the number of shares then subject to
options under this Plan, or expected to be subject to options under this Plan in the then pending offering(s), to be issued or transferred to, or acquired by, a trust (including but not limited to a grantor trust) for the purpose of satisfying the
Company’s obligations under such options, and, unless prohibited by applicable law, such shares held in trust shall be considered authorized and issued shares with full dividend and voting rights, notwithstanding that the options to which such
shares relate might not be exercisable at the time. No fractional shares of Common Stock shall be issued or sold under the Plan. 

  

	5.	Eligibility 

 All employees of the Company and any
Subsidiaries designated by the Committee from time to time will be eligible to participate in the Plan, in accordance with and subject to such rules and regulations as the Committee may prescribe; provided, however, that (a) such rules shall
neither permit nor deny participation in the Plan contrary to the requirements of the Code (including but not limited to Section 423(b)(3), (4) and (8) thereof), (b) no employee shall be eligible to participate in the Plan if his
or her customary employment is 20 hours or less per week or for not more than 5 months in any calendar year, unless the Committee determines otherwise on a uniform and non-discriminatory basis, (c) no employee may be granted an option under the
Plan if such employee, immediately after the option is granted, owns stock possessing 5% or more of the total combined voting power or value of all classes of stock of his or her employer corporation or any parent or Subsidiary corporation (within
the meaning of Section 423(b)(3) of the Code). For purposes of the preceding sentence, the rules of Section 424(d) of the Code shall apply in determining the stock 

  

 -3- 








 
ownership of an employee, and stock which the employee may purchase under outstanding options (whether or not such options qualify for the special tax
treatment afforded by Code Section 421(a)) shall be treated as stock owned by the employee; and (d) all participating employees shall have the same rights and privileges except as otherwise permitted by Section 423(b)(5) of the Code.

  

	6.	Offerings; Participation 

 The Company may make
offerings of up to 27 months’ duration each, to eligible employees to purchase Common Stock under the Plan, until all shares authorized to be delivered under the Plan have been exhausted or until the Plan is sooner terminated by the Board.
Subject to the preceding sentence, the duration and commencement date of any offerings shall be determined by the Committee in its sole discretion; provided that, unless the Committee determines otherwise, a new offering shall commence on the first
day of the Company’s first payroll period coinciding with or next following each January 1 after the effective date of this Plan and shall extend through and include the payroll period immediately preceding the payroll period in which the
next offering commences. Subject to such rules, procedures and forms as the Committee may prescribe, an eligible employee may participate in an offering at such time(s) as the Committee may permit by authorizing a payroll deduction for such purpose
of up to a maximum of ten percent of his or her Base Compensation or such lesser amount as the Committee may prescribe. The Committee may (but need not) permit employee contributions to be made by means other than payroll deductions, provided that
in no event shall an employee’s contributions from all sources in any offering exceed ten percent of his or her Base Compensation or such lesser amount as the Committee may prescribe. The Committee may at any time suspend or accelerate the
completion of an offering if required by law or deemed by the Committee to be in the best interests of the Company, including in the event of a change in ownership or control of the Company or any Subsidiary. The Company’s obligation to sell
and deliver Common Stock under this Plan shall be subject to the approval of any governmental authority whose approval the General Counsel determines is necessary or advisable to obtain in connection with the authorization, issuance or sale of such
Common Stock. 
  

	7.	Payroll Deductions 

  

	 	(a)	The Company will maintain payroll deduction accounts on its books for all participating employees. All employee contributions shall be credited to such accounts. Employee
contributions credited to the payroll deduction accounts of participating employees need not be segregated from other corporate funds and may be used for any corporate purpose. 

  

	 	(b)	At such times as the Committee may permit and subject to such rules, procedures and forms as the Committee may prescribe, an employee may increase, decrease or suspend his or her
payroll deduction during an offering, or may withdraw the balance of his or her payroll deduction account and thereby withdraw from participation in an offering. However, an employee may at any time waive in writing the right or privilege to
decrease or suspend his or her payroll deductions or withdraw from participation in a particular offering for a period of at least six months. Any such waiver shall be irrevocable with respect to the period ending six months after the employee files
a superseding written revocation of such waiver with the Company. 

  

 -4- 









	 	(c)	No employee shall make any elective contribution or employee contribution to the Plan (within the meaning of Treasury Regulation Section 1.401(k)-1(d)(2)(iv)(B)(4)) during the
balance of the calendar year after the employee’s receipt of a hardship distribution from a plan of the Company or a related party within the provisions of Code Section 414(b), (c), (m) or (o) containing a cash or deferred
arrangement under Section 401(k) of the Code, or during the following calendar year. The foregoing sentence shall not apply if and to the extent the General Counsel determines it is not necessary to qualify any such plan as a cash or deferred
arrangement under Section 401(k) of the Code. 

  

	 	(d)	Any balance remaining in any employee’s payroll deduction account at the end of an offering period will be carried forward into the employee’s payroll deduction account
for the following offering period. In no event will the balance carried forward be equal to or greater than the purchase price of one share of Common Stock as determined under Section 8(c) below. Any excess shall be refunded to the participant.
Upon termination of the Plan, all amounts in the accounts of participating employees shall be carried forward into their payroll deduction accounts under a successor plan, if any, or refunded to them, as the Committee may decide.


  

	 	(e)	In the event of the termination of a participating employee’s employment for any reason, his or her participation in any offering under the Plan shall cease, no further amounts
shall be deducted pursuant to the Plan and the balance in the employee’s account shall be paid to the employee, or, in the event of the employee’s death, to the employee’s beneficiary under the Company’s basic group life
insurance program. 

  

	8.	Purchase; Limitations 

  

	 	(a)	Within the limitations of Section 8(d) below, each employee participating in any offering under the Plan will be granted an option, upon the effective date of such offering,
for as many full shares of Common Stock as the amount of his or her payroll deduction account (including any contributions made by means other than payroll deductions) at the end of the offering can purchase. 

  

	 	(b)	As of the last day of the offering period, the payroll deduction account of each participating employee shall be totaled. Subject to the provisions of Section 7(b) above and
8(d) below, if such account contains sufficient funds as of that date to purchase one or more full shares of Common Stock at the price determined under Section 8(c) below, the employee shall be deemed to have exercised an option to purchase the
largest number of full shares of Common Stock at the price determined under Section 8(c) below that his or her payroll deduction account will permit; such employee’s account will be charged for the amount of the purchase and for all
purposes under the Plan the employee will be deemed to have acquired the shares on that date; and either a stock certificate representing such shares will be issued to him or her, or the Company’s registrar will make an entry on its books and
records evidencing that such shares have been duly issued or transferred as of that date, as the Committee may direct. Notwithstanding any provision of the Plan to the contrary, the Committee may but need not permit fractional shares to be purchased
under the Plan. 

  

 -5- 









	 	(c)	Unless the Committee determines before the effective date of an offering that a higher price that complies with Section 423 of the Code shall apply, the purchase price of the
shares of Common Stock which are to be sold under the offering shall be the lesser of (i) an amount equal to 85 percent of the Fair Market Value of the Common Stock at the time such option is granted, or (ii) an amount equal to 85 percent
of the Fair Market Value of the Common Stock at the time such option is exercised. 

  

	 	(d)	In addition to any other limitations set forth in the Plan, (i) no employee may purchase in any offering period more than the number of shares of Common Stock determined by
dividing the employee’s annual Base Compensation as of the first day of the offering period, or $25,000, whichever is less, by the Fair Market Value of a share of Common Stock at such day, and (ii) no employee may be granted an option
under the Plan which permits his or her rights to purchase stock under the Plan, and any other stock purchase plan of his or her employer corporation and its parent and subsidiary corporations that is qualified under Section 423 of the Code, to
accrue at a rate which exceeds $25,000 of the Fair Market Value of such stock (determined at the time such option is granted) for each calendar year in which the option is outstanding at any time. The Committee may further limit the amount of Common
Stock which may be purchased by any employee during an offering period in accordance with Section 423(b)(5) of the Code. 

  

	9.	No Transfer 

  

	 	(a)	No option, right or benefit under the Plan (including any derivative security within the meaning of paragraph (a)(2) of SEC Rule 16b-3) may be transferred by a participating
employee, whether by will, the laws of descent and distribution, or otherwise, and all options, rights and benefits under the Plan may be exercised during the participating employee’s lifetime only by such employee. 

  

	 	(b)	Book entry accounts and certificates for shares of Common Stock purchased under the Plan may be maintained or registered, as the case may be, only in the name of the participating
employee or, if such employee so indicates on his or her payroll deduction authorization form, in his or her name jointly with a member of his or her family, with right of survivorship. An employee who is a resident of a jurisdiction which does not
recognize such a joint tenancy may have book entry accounts maintained and certificates registered in the employee’s name as tenant in common with a member of the employee’s family, without right of survivorship. 


 

	10.	Effective Date and Duration of Plan 

 The Plan shall
become effective when adopted by the Board, provided that the stockholders of the Company approve it within 12 months thereafter at a duly held stockholders’ meeting. If not so approved by shareholders, the Plan shall be null, void and of no
force or effect. If so approved, the Plan shall remain in effect until all shares authorized to be issued or transferred hereunder have been exhausted or until the Plan is sooner terminated by the Board of Directors, and may continue in effect
thereafter with respect to any options outstanding at the time of such termination if the Board of Directors so provides.

	11.	Amendment and Termination of the Plan 

 The Plan may
be amended by the Board of Directors, without shareholder approval, at any time and in any respect, unless shareholder approval of the amendment in question is required under Oklahoma law, the Code (including without limitation Code Section 423
and Treasury Regulation Section 1.423-2(c)(4) thereunder), any exemption from Section 16 of the Exchange Act (including without limitation SEC Rule 16b-3) for which the Company intends Section 16 Persons to qualify, any national
securities exchange or system on which the Stock is then listed or reported, by any regulatory body having jurisdiction with respect to the Plan, or under any other applicable laws, rules or regulations. The Plan provisions that determine the
amount, price and timing of option grants to Section 16 Persons may not be amended more than once every six months, other than to comport with changes in the Internal Revenue Code, the Employee Retirement Income Security Act of 1974, or the
rules thereunder, unless the General Counsel determines that such restriction on amendments is not necessary to secure or maintain any exemption from Section 16 of the Exchange Act for which the Company intends Section 16 Persons to
qualify. The Plan may also be terminated at any time by the Board of Directors. 
  

	12.	General Provisions 

  

	 	(a)	Nothing contained in this Plan shall be deemed to confer upon any person any right to continue as an employee of or to be associated in any other way with the Company for any period
of time or at any particular rate of compensation. 

  

	 	(b)	No person shall have any rights as a stockholder of the Company with respect to any shares optioned under the Plan until such shares are issued or transferred to him or her.


  

	 	(c)	All expenses of adopting and administering the Plan shall be borne by the Company, and none of such expenses shall be charged to any participant. 

  

	 	(d)	The Plan shall be governed by and construed under the laws of the State of Oklahoma, without giving effect to the principles of conflicts of laws of that State.


  

	 	(e)	The Plan and each offering under the Plan is intended to qualify as an employee stock purchase plan within the meaning of Section 423 of the Code. Transactions under the Plan
by or with respect to Section 16 Persons are also intended to qualify for exemption under SEC Rule 16b-3, unless the Committee specifically determines otherwise. Every provision of the Plan shall be administered, interpreted and construed to
carry out those intentions, and any provision that cannot be so administered, interpreted and construed shall to that extent be disregarded.
