{00113938 2 } 1 ARTICLE 1. PURPOSE AND EFFECTIVE DATE 1.1 Purpose. The purpose of the Plan is to provide a select group of primarily management or highly compensated employees of the Employer the option to defer the receipt of portions of their compensation payable for services rendered to the Employer, and provide nonqualified deferred compensation benefits which are not available to such employees by reason of limitations on employer and employee contributions to qualified pension or profit-sharing plans under the federal tax laws. 1.2 Effective Date. The ONEOK, Inc. 2020 Nonqualified Deferred Compensation Plan is effective January 1, 2020, with respect to Base Compensation for payroll periods ending, and Incentive Compensation for services provided, on or after the Effective Date. 1.3 Definitions. Capitalized terms are defined in ARTICLE II.

{00113938 2 } 2 ARTICLE 2. PARTICIPATION 2.1 Commencement of Participation. Each Eligible Employee shall become a Participant either upon the earlier of (i) the initial submission of an Election, or (ii) first receiving an allocation of Employer Contributions or Supplemental Retirement Contributions. 2.2 Special Rule for Initial Participation. Within 30 days after the date an individual first becomes an Eligible Employee, the individual may elect to commence participating with respect to compensation to be paid for services performed after the election is filed. This election relating to initial participation in the Plan is available only to Participants who do not participate in any Aggregated Plans. If an Employee whose participation in the Plan is terminated again becomes an Eligible Employee, he or she may elect to defer pursuant to this Section only if the Employee was ineligible to defer compensation in any Aggregated Plans for the 24 months preceding the date on which the Participant again became eligible to participate in this Plan. 2.3 Termination of Participation Subject to Section 3.5, regarding the irrevocability of a Participant’s Election, the Committee may, for any reason, terminate a Participant's participation in the Plan and the Participant shall cease to be an Eligible Employee as of the date specified by the Committee. The terms of this Plan shall continue to govern Participant’s Account until the Participant’s Account is paid in full.

{00113938 2 } 3 ARTICLE 3. PARTICIPANT ELECTIVE CONTRIBUTIONS 3.1 Deferral Agreement. Base Compensation. Each Eligible Employee may defer a portion of Base Compensation for such upcoming Plan Year by executing an Election deferring such Base Compensation during the Election Period. Incentive Compensation. Each Eligible Employee may defer a portion of Incentive Compensation for such upcoming Plan Year by executing an Election deferring such Incentive Compensation during the Election Period. 3.2 Amount of Deferral. An Eligible Employee may elect to defer between 2% and 90% of his or her Base Compensation and between 10% and 90% of his or her Incentive Compensation for a Plan Year; provided, however, that such deferrals shall be made in whole percentages. The deferral amount is the amount designated on the Participant’s Election. 3.3 Evergreen. A Participant’s Election shall remain in full force and effect for all subsequent years until modified or revoked in writing during an Election Period or terminated in accordance with Section 3.5. If a Participant’s Election has been deemed continued for a Plan Year in accordance with this Section, it is irrevocable for such Plan Year. 3.4 Timing of Election. Incentive Compensation. The Election Period for Incentive Compensation shall be within the fourth fiscal quarter of the calendar year immediately preceding the calendar year in which the Incentive Compensation is earned with the specific time period determined annually in the discretion of the Committee (or designee thereof). Subject to Section 3.3, above, if a Participant desires to amend or modify the deferral of Incentive Compensation a new Election must be timely executed for each Plan Year during the applicable Election Period. An Eligible Employee who does not timely execute an Election during his or her initial Election Period to defer Incentive Compensation shall be deemed to have elected zero deferrals of Incentive Compensation for such Plan Year and each subsequent Plan Year until a timely Election is made. Notwithstanding the foregoing, in the discretion of the Committee, the Committee may provide that the Election Period for Incentive Compensation (that also qualifies as performance based compensation within the meaning of Section 409A) for a Plan Year may begin on June 1st and end on June 30th of that Plan Year. If the Committee provides such Election Period for Incentive Compensation, in no event shall the last day of any Election Period to defer Incentive Compensation be later then the date that is six months before the end of the performance period, provided that the Participant performs services continuously from the later of the beginning of the performance period or the date the performance criteria are established through the date an election is made, and provided further that in no event may any Participant elect to defer Incentive Compensation after such compensation has become readily ascertainable.

{00113938 2 } 4 Base Compensation. The Election Period for Base Compensation shall be within the fourth calendar quarter of the year immediately preceding the calendar year in which the Base Compensation is earned with the specific time period determined annually in the discretion of the Committee (or designee thereof). Subject to Section 3.3, above, if a Participant desires to amend or modify the deferral of Base Compensation a new Election must be timely executed for each Plan Year during the applicable Election Period. An Eligible Employee who does not timely execute an Election during his or her initial Election Period shall be deemed to have elected zero deferrals of Base Compensation for such Plan Year and each subsequent Plan Year until a timely Election is made. Pre-Effective Date Election Period. For purposes of the initial Plan Year beginning January 1, 2020, the Election Period for Eligible Employees prior to the Effective Date of the Plan (who are identified to as eligible to become Participants in the Plan on January 1, 2020) shall be established by and in the Committee’s discretion during the period of October 1, 2019 through December 31, 2019 and shall apply to all Base Compensation for payroll periods ending, and Incentive Compensation for services provided, on or after the Effective Date. 3.5 Irrevocability, Generally. Except as otherwise provided in Section 3.4, an Election with respect to a Plan Year may not be changed or revoked for that Plan Year after the last day of the Election Period. A Participant's deferral Election for the remainder of the Plan Year will be cancelled on account of the Participant's Disability in accordance with Treasury Regulation Section 1.409A-3(j)(4)(xii). 3.6 Withholding of Deferrals. The Employer shall have the sole discretion to withhold the percentage of Base Compensation, and Incentive Compensation specified in a Participant’s Election for a Plan Year at the times and in the amounts that the Employer, in its sole discretion, selects, which need not be uniform either among Participants or as to payments to a single Participant; provided, however, that deferral amounts must be withheld not later than the end of the calendar year during which the Company would otherwise have paid the amounts to the Participant but for the Participant’s Election. Deferrals of Base Compensation shall not be withheld during any period in which the Participant is on an unpaid leave of absence. All deferral amounts that are withheld in accordance with this Section shall be deemed for all purposes to comply with the Plan requirements regarding deferrals.

{00113938 2 } 5 ARTICLE 4. EMPLOYER CONTRIBUTIONS 4.1 Employer Contributions. Employer Contribution. Each Plan Year, the Employer shall credit to the Account of each Participant who is an Eligible Employee on the last day of the Plan Year (except for any Participant whose Separation from Service was as a result of death, Disability or Retirement) an amount equal 6% of Eligible Compensation. Supplemental Retirement Contribution Each Plan Year, the Employer shall credit to the Account of each Participant who is not eligible for or participating in the ONEOK, Inc. 2005 Supplemental Executive Retirement Plan during the Plan Year and who is an Eligible Employee on the last day of the Plan Year (except for any Participant whose Separation from Service was as a result of death, Disability or Retirement) a Supplemental Retirement Contribution in an amount equal to the total of subsections: (i), (ii), and (iii, if any) as described below: (i) An amount equal 1% of Eligible Compensation. (ii) A discretionary percentage of Eligible Compensation generally based on the profit sharing contribution issued for the Plan Year to eligible employees under the ONEOK, Inc. 401(k) Plan for the Plan Year. (iii) A supplemental amount determined by the Committee, in its sole discretion. 4.2 Timing of Employer Contributions. Employer Contributions and Supplemental Employer Contributions shall be credited to the Participant’s Account as soon as administratively practicable on or following the last day of each Plan Year.

{00113938 2 } 6 ARTICLE 5. PAYMENT SCHEDULE AND FORM OF PAYMENT. Subject to ARTICLE 6, Plan Accounts shall be distributed in accordance with the provisions of this Article. 5.1 Distribution Date. Amounts allocated to the Participant's Account shall be paid, or begin to be paid, upon the earliest of: (i) a date, specified in the Participant’s Election, that is no earlier than the January 1 following the 5th anniversary of the Participant’s Election; ii) the Participant’s Separation from Service; (iii) the Participant’s death; (iv) the Participant’s Disability, or (v) a Change in Control. If a Participant does not have an Election with respect to contributions for specific Plan Year, including an evergreen Election pursuant to Section 3.3, or if for any reason the Participant’s Election for a Plan Year is invalid, the Participant’s Account attributable to that Plan Year shall be paid upon the Participant’s Separation from Service. 5.2 Form of Distribution. Upon the occurrence of a distribution date in Section 5.1, the Participant's Account shall be paid, or begin to be paid, in one of the following forms as specified in the Participant’s Election (or Subsequent Election): (i) a single lump sum; (ii) annual installments over 5 years; or (iii) annual installments over 10 years. Notwithstanding the foregoing, at any time and in its discretion, the Committee may determine that the number of separate Elections as to the time and form of a distribution shall be limited. Following the Committee’s decision to implement a limit, any Participant Election specifying additional times and forms of distribution in excess of such limit will be invalid. In the event there is no Participant Election with respect to a Participant’s contributions for a specific Plan Year, or if for any reason the Participant’s Election for a Plan Year is invalid, that portion of a Participant’s Account shall be paid in a single lump sum. 5.3 Unforeseeable Emergency. A Participant may submit a written request for a distribution on account of an Unforeseeable Emergency. Upon approval by the Committee of a Participant’s request, the Participant’s Account, or that portion of a Participant’s Account deemed necessary by the Committee to satisfy the Unforeseeable Emergency (determined in a manner consistent with Section 409A) plus amounts necessary to pay taxes reasonably anticipated because of the distribution, will be distributed in a single lump sum. 5.4 Distributions to Specified Employees. Notwithstanding any other provision of the Plan, if any payment or benefit provided to a Participant in connection with his or her Separation from Service is determined to constitute "nonqualified deferred compensation" within the meaning of Section 409A of the Code and the Participant is determined to be a "specified employee" as defined in Section 409A(a)(2)(b)(i) of the Code, then such payment or benefit shall not be paid, or commence to be paid, until (i) the first payroll date to occur following the six-month anniversary of the Separation from Service; or (ii) if earlier, on the Participant’s death (the "Specified Employee Payment Date"). 5.5 Subsequent Elections. In accordance with rules, procedures and forms specified from time to time by the Committee, a Participant may file a Subsequent Election to change the time on which the distribution is to commence or the form in which the Participant’s Account is

{00113938 2 } 7 distributed, or both. A Participant may file a Subsequent Election only if it complies with the provisions of section 409A of the Code and Treasury Regulations and the following conditions are met: The Subsequent Election shall not take effect until at least twelve (12) months after the date on which it is made; Except in the case of an election permitted under Section 409A and the Treasury Regulations §1.409A-3(a)(2) (payment on account of disability), § 1.409A-3(a)(3) (payment on account of death), or §1.409A-3(a)(6) (payment on account of the occurrence of an unforeseeable emergency), the payment with respect to which such Subsequent Election shall be deferred for a period of five (5) years from the date such payment would otherwise have been paid (or in the case of installment payments treated as a single payment, five (5) years from the date the first amount was scheduled to be paid); and Any Subsequent Election related to a payment described in Treasury Regulations §1.409A-3(a)(4) (payment at a specified time or pursuant to a fixed schedule) shall be made not less than twelve (12) months before the date the payment is scheduled to be paid (or in the case of a life annuity or installment payments treated as a single payment, twelve (12) months before the date the first amount was scheduled to be paid). A Participant who has made a prior Subsequent Election under the Plan shall be allowed to make another Subsequent Election in accordance with this Section 5.5 and other provisions of the Plan. The Committee, or its designee, shall be authorized to administer, construe and interpret the foregoing provisions and the Plan with respect to all Subsequent Elections to assure compliance with the intent thereof and the requirements of the Plan and of Section 409A of the Code and Treasury Regulations.

{00113938 2 } 8 ARTICLE 6. SPECIAL DISTRIBUTION RULES 6.1 Permissible Accelerations of Distributions Except as otherwise provided in the Plan and except as may be allowed in guidance from the Secretary of the Treasury, distributions from a Participant’s Account may not be made earlier than the time such amounts would otherwise be distributed pursuant to the terms of the Plan. Taxes. The Employer, in its sole discretion, may accelerate the time in which payment shall be made under the Plan to: (a) pay the FICA tax imposed under Code Sections 3101, 3121(a) and 3121(v)(2) on compensation deferred under the Plan, (b) pay the income tax at source on wages imposes under Code Section 3401 or the corresponding withholding provisions of the applicable, state, local or foreign tax laws as a result of the payment of any FICA tax described in clause (a), and to pay the additional income tax at source on wages attributable to the pyramiding Code Section 3401 wages and taxes, (c) pay state, local, or foreign tax obligations arising from participation in the Plan that apply to an amount deferred under the Plan before the amount is paid or made available to the Participant, (d) pay the income tax at source on wages imposed under Code Section 3401 as a result of the payment described in clause (d) and to pay the additional income tax at source on wages imposed under Code Section 3401 attributable to such additional Code Section 3401 wages and taxes, (e) pay the amount required to be included in gross income as a result of the failure of the Plan to comply with the requirements of Code Section 409A. The total payment under clauses (a) and (b) shall, in no event, exceed the aggregate of the FICA tax and the income tax withholding related to such FICA tax. The total payment under clause (c) shall, in no event, exceed the amount of such taxes due as a result of participation in the Plan. The total payment under clauses (c) and (d) shall, in no event, exceed the aggregate of the state, local, and foreign tax amount, and the income tax withholding related to such state, local, and foreign tax amount. The total payment under clause (e) shall, in no event, exceed the amount required to be included in income as a result of the failure to comply with requirements of Code Section 409A. Compliance with Ethics Laws or Conflicts of Interests Laws. The Committee is authorized, in its sole discretion, to accelerate the time or schedule of a payment to the extent reasonably necessary to avoid the violation of an applicable federal, state, local, or foreign ethics law or conflicts of interest law (including where such payment is reasonably necessary to permit the Participant to participate in activities in the normal course of his position in which the Participant would otherwise not be able to participate under an applicable rule), determined in accordance with Section 409A. Small Accounts. The Committee may, in its sole discretion, distribute in a single lump sum the aggregate amounts credited to the Participant’s Account, along with any related earnings, provided: (i) the distribution results in the payment of the Participant’s entire interest in the Account and all Aggregated Plans, and (ii) the total payment does not exceed the applicable dollar limit under Code section 402(g)(1)(B). The Committee shall notify the Participant in writing if the Committee exercises its discretion pursuant to this Section.

{00113938 2 } 9 Settlement of a Bona Fide Dispute. The Committee may, in its sole discretion, accelerate the time or schedule of a distribution as part of a settlement of a bona fide dispute between the Participant and the Employer over the Participant’s right to a distribution provided that the distribution relates only to the deferred compensation in dispute and the Employer is not experiencing a downturn in financial health. Settlement of Debt. The Committee may, in its sole discretion, accelerate the time or schedule of a payment to satisfy the debt of a Participant to the Employer or any Related Employer where such debt is incurred in the ordinary course of the service relationship between the Participant and the Employer or Related Employer, as applicable, the entire amount of the reduction in any Plan year does not exceed $5,000, and the reduction is made at the same time and in the same amount as the debt otherwise would have been due and collected from the Participant. 6.2 Permissible Delays in Payment. Distributions may be delayed beyond the date payment would otherwise occur in accordance with the Plan in any of the following circumstances: Payments that would violate Federal Securities Laws or Other Applicable Law. The Employer may also delay payment if it reasonably anticipates that the marking of the payment will violate Federal securities laws or other applicable laws provided payment is made at the earliest date on which the Employer reasonably anticipates that the making of the payment will not cause such violation. Going Concern. If the distribution would jeopardize the Employer’s ability to continue as a going concern, provided that the delayed amount is distributed in the first calendar year in which the payment would not have such effect. Inability to Calculate. If calculation of the amount of the payment is not administratively practicable due to events beyond the control of the Participant (or Participant's Beneficiary), the payment will be treated as made upon the date contemplated by the Plan if the payment is made during the first calendar year in which the payment is administratively practicable. Other Events and Conditions. The Employer also reserves the right to delay payment upon such other events and conditions as the Secretary of the Treasury may prescribe in generally applicable guidance published in the Internal Revenue Bulletin. 6.3 General Timing Rules. The general rules in this section shall apply to all Plan distributions. Except as otherwise provided in this section, if a distribution is required upon the occurrence of an event specified in Section 5.1, the distribution will commence between the date of the distribution event and the later of (i) the end of the year in which the distribution event occurs, and (ii) 15th day of the third calendar month following the distribution event; provided, however, the Participant will not be permitted, directly or indirectly, to designate the taxable year of the

{00113938 2 } 10 distribution. If a Participant has elected to receive a distribution commencing during a specific calendar year, the distribution may occur any time during that year; provided, however, that if an Participant’s Election specifies a particular month during which the distribution should commence, the distributions may not commence before the first day of the specified month. Any distribution that complies with this section shall be deemed for all purposes to comply with the Plan requirements regarding the time and form of distributions.

{00113938 2 } 11 ARTICLE 7. ACCOUNTS AND CREDITS/OTHER ADJUSTMENTS 7.1 Contribution Credits to Account. A Participant's Account will be credited for each Plan Year with: (a) the amount of the Participant’s elective deferrals in accordance with ARTICLE 3, and the amount of any Employer Contributions or Supplemental Retirement Contributions credited on his behalf annually under ARTICLE 4. Separate Accounts shall be maintained for each Participant for each Plan Year for which contributions are credited to the Participant. 7.2 Vesting. A Participant shall always be 100% vested in all contributions allocated to the Participant’s Account. 7.3 Earnings Credits to Account. The Participant's Account shall be credited (or debited) on each Valuation Date with income (or loss) based upon a hypothetical investment in any one or more of the investment options available under the Plan, as prescribed by the Committee. In the absence of any affirmative investment decision by the Committee (or any delegate thereof), the investment options available under the Plan shall mirror the then current investment options offered to participants under the ONEOK, Inc. 401(k) Plan (or any successor thereto), excluding common stock of the Employer and any investment fund frozen to new contributions. The crediting or debiting on each Valuation Date of income (or loss) shall be made for each respective Account. All investments of a Participant’s Account shall be valued at fair market value. Additionally, all distributions, investments and investment exchanges allowed and made under the Plan shall be as of the relevant Valuation Date at fair market value. 7.4 Adjustment of Accounts. Each Account maintained for a Participant shall be adjusted for interest credits and any expenses allocable under the terms of the Plan to the Account. The Account shall be adjusted as of each Valuation Date to reflect: (a) the earnings credits and expenses described under Section 7.3, above; (b) amounts credited pursuant to ARTICLE 3 and ARTICLE 4; and (c) distributions or withdrawals.

{00113938 2 } 12 ARTICLE 8. AMENDMENT AND TERMINATION 8.1 Amendment by Employer. The Employer may at any time amend the Plan in whole or in part, except that no amendment may reduce the value of any Participant’s Account. An amendment must be in writing and executed by a representative of the Employer authorized to take such action. 8.2 Plan Terminations. The Employer retains the discretion to terminate the Plan and distribute each Participant’s Account in a single lump sum if (1) the termination does not occur proximate to a downturn in the financial health of the Employer; (2) all Aggregated Plans are terminated, (3) no payments other than payments that would be payable under the terms of the arrangements if the termination had not occurred are made within 12 months of the termination of the arrangements, (4) all payments are made within 24 months of the termination of the arrangements, and (5) neither the Employer nor any Related Employer adopts a new arrangement that would be aggregated with any terminated arrangement under Treasury Regulation Section 1.409A-1(c), if the same service provider participated in both arrangements, at any time with the three year period following the date of termination of the arrangement. Automatic Termination following distribution of all Accounts. The Plan will terminate automatically as of the date that no amounts remain to be distributed under the Plan. In connection with change in control. The Employer reserves the right to terminate the Plan and accelerate the time of payment of all amounts to be distributed under the Plan in accordance with the following provisions of this Section 8.2. The Employer may make an irrevocable election to terminate the Plan and distribute all amounts credited to all Participant Accounts within the 30 days preceding or the 12 months following a Change in Control. For this purpose, the Plan will be treated as terminated only if all other Aggregated Plans are terminated and liquidated with respect to each Participant that experienced the Change in Control, so that under the terms of the termination and liquidation all such Participants are required to receive all amounts of compensation deferred under the terminated arrangements within 12 months of the date the Employer irrevocably takes all necessary action to terminate and liquidate the Plan and such other arrangements.

{00113938 2 } 13 ARTICLE 9. PLAN ADMINISTRATION 9.1 Committee; Duties. This Plan shall be administered by the Committee. The Committee shall have the authority to make, amend, interpret and enforce all appropriate rules and regulations for the administration of the Plan and decide or resolve any and all questions, including interpretations of the Plan, as they may arise in such administration. 9.2 Binding Effect of Decisions. The decision or action of the Committee with respect to any question arising out of or in connection with the administration, interpretation and application of the Plan and the rules and regulations promulgated hereunder shall be final, conclusive and binding upon all persons having any interest in the Plan. 9.3 Delegation of the Committee’s Powers and Responsibilities. The Committee may appoint an entity or individual, who may be an employee of the Employer or a third party, to be the Committee’s agent with respect to the day-to-day administration of the Plan. In addition, the Committee may, from time to time, employ other agents and delegate to them such administrative duties as it sees fit, and may from time to time consult with counsel who may be counsel to the Employer. Except for settlor duties and responsibilities that are specifically reserved to the Employer, the Board or the Committee (including, but not limited to, the ability to terminate the Plan or approve amendments to the Plan), or which have been properly delegated to another person or entity under the terms of the Plan, all settlor duties and responsibilities with respect to the Plan are delegated to the ONEOK, Inc. Benefit Plan Sponsor Committee, with the exception of the following duties and responsibilities which shall be delegated to the President and Chief Executive Officer of the Employer: (i) Amendments which constitute routine, ministerial, clarifying or conforming amendments and do not materially modify the provision or intent of the Plan; (ii) To decide all questions concerning the Plan and the eligibility of any person to participate in the Plan, in its sole discretion, subject to review by the Committee; and (iii) To determine the amount of any benefit or contribution or to increase any benefit or contribution under the Plan (except for such increases which related to the delegate’s own deferred compensation), so long as such increase does not exceed One Million Dollars ($1,000,000) for any Plan Year. Except for such duties and responsibilities as may be specifically reserved to the Employer, the Board, the Committee or the ONEOK, Inc. Benefit Plan Sponsor Committee, or which have been properly delegated to another person or entity under the terms of the Plan, the

{00113938 2 } 14 ONEOK, Inc. Benefit Plan Administration Committee shall be responsible for the discretionary administration of the Plan. 9.4 Indemnification. To the fullest extent allowed by law, the Employer shall indemnify and hold harmless each member of the Committee and each employee, officer, or director of the Employer or any Related Employer to whom is delegated duties, responsibilities, and authority with respect to the Plan against all claims, liabilities, fines and penalties, and all expenses reasonably incurred by or imposed upon him (including but not limited to reasonable attorneys' fees) which arise as a result of his actions or failure to act in connection with the operation and administration of the Plan to the extent lawfully allowable and to the extent that such claim, liability, fine, penalty, or expense is not paid for by liability insurance purchased or paid for by the Employer or and Related Employer. Notwithstanding the foregoing, the Employer shall not indemnify any person for any such amount incurred through any settlement or compromise of any action unless the Employer consents in writing to such settlement or compromise. 9.5 Claims and Review Procedures Claims Procedure. If any person believes he is being denied any rights or benefits under the Plan, such person (the “Claimant”) may file a claim in writing with the Committee, or designee thereof (the “Claims Administrator”). If any such claim is wholly or partially denied, the Claims Administrator will notify such person of its decision in writing. Such notification will contain (i) specific reasons for the denial, (ii) specific reference to pertinent Plan provisions, (iii) a description of any additional material or information necessary for such person to perfect such claim and an explanation of why such material or information is necessary, and (iv) information as to the steps to be taken if the person wishes to submit a request for review. Such notification will be given within 90 days after the claim is received by the Claims Administrator (or within 180 days, if special circumstances require an extension of time for processing the claim, and if written notice of such extension and circumstances is given to such person within the initial 90 day period). If such notification is not given within such period, the claim will be considered denied as of the last day of such period and such person may request a review of his claim. Review Procedure. Within 60 days after the date on which a person receives a written notification of denial of claim (or, if written notification is not provided, within 60 days of the date denial is considered to have occurred), such person (or his duly authorized representative) may (i) file a written request with the Claims Administrator for a review of his denied claim and of pertinent documents and (ii) submit written issues and comments to the Claims Administrator. The Claims Administrator will notify such person of its decision in writing. Such notification will be written in a manner calculated to be understood by such person and will contain specific reasons for the decision as well as specific references to pertinent Plan provisions. The decision on review will be made within 60 days after the request for review is received by the Claims Administrator (or within 120 days, if special circumstances require an extension of time for processing the request, such as an election by the Claims Administrator to hold a hearing, and if written notice of such extension and circumstances is given to such person within the initial 60-day period). If the decision on review is not made within such period, the claim will be considered

{00113938 2 } 15 denied. Except as otherwise provided in Section 9.5, the decision, action or inaction of the Claims Administrative shall be final, conclusive and binding on all persons having an interest in the Plan. Mandatory Arbitration. If, after exhausting the procedures set forth in this Section, a Claimant wishes to pursue legal action, any action by the Claimant with respect to a claim made under Section 9.5, must be resolved by arbitration in the manner described in this Section.

(i) Time Limits. A Claimant seeking arbitration of any determination of the Claims Administrator must, within six (6) months of the date of the Claims Administrator’s final decision, file a demand for arbitration with the American Arbitration Association submitting the claim to resolution by arbitration.

{00113938 2 } 16 Participants agree that any Claim may only be initiated or maintained and decided on an individual basis. (vii) Standard of Review. Any decision of an Arbitrator on a claim shall be limited to determining whether the Claim Administrator’s decision or action was arbitrary or capricious or was unlawful.

Glenn, 554 U.S. 105 (2008), and Firestone Tire and Rubber Co. v.

(1) Arbitration Rules. The arbitration hearing will be conducted under the AAA Commercial Arbitration Rules (as amended or revised from time to time by AAA) (hereinafter the “AAA Rules”), before one AAA arbitrator who is from the Large, Complex Case Panel and who has experience with matters involving executive compensation and equity compensation plans. The AAA Rules and the terms and procedures set forth here may conflict on certain issues. To the extent that the procedures set forth here conflict with the AAA Rules, the procedures set forth here shall control and be applied by the arbitrator. Notwithstanding the amount of the claim, the Procedures for Large, Complex Commercial Disputes shall not apply. (2) Substantive Law. The arbitrator shall apply the substantive law (and the laws of remedies, if applicable), of Oklahoma or federal law, or both, depending upon the claim. Except to the extent required by applicable law, all arbitration decisions and awards shall be kept strictly confidential and shall not be disclosed by the Claimant to anyone other than the Claimant’s spouse, attorney or tax advisor. (3) Authority. The arbitrator shall have jurisdiction to hear and rule on prehearing disputes and is authorized to hold prehearing conferences by telephone or in person as the arbitrator deems necessary. The arbitrator will have the authority to hear a motion to dismiss and/or a motion for summary judgment by any party and in doing so shall apply the standards governing such motions under the Federal Rules of Civil Procedure.

(5) Fees and Costs. Administrative arbitration fees and arbitrator compensation shall be borne equally by the parties, and each party shall be responsible for its own attorney’s fees, if any; provided, however, that the Committee will authorize payment by the Employer of all administrative arbitration fees, arbitrator compensation and attorney’s fees if the Committee concludes that a Claimant has substantially prevailed on his or her claims. Unless prohibited by statute, the arbitrator shall assess attorney’s fees against a party upon a showing that such party’s claim, defense or position is frivolous, or unreasonable, or factually groundless. If either party pursues a claim by any means other than those set forth in this Section, the responding party shall be entitled to dismissal of such action, and the recovery of all costs and attorney’s fees and losses related to such action, unless prohibited by statute. (ix) Interstate Commerce and the Federal Arbitration Act. The Employer is involved in transactions involving interstate commerce, and the employee’s employment with the Employer involves such commerce. Therefore, the Arbitration Act will govern the interpretation, enforcement, and all judicial proceedings regarding the arbitration procedures in this Section. 9.6 Disability Determinations.

Participants and their Beneficiaries, heirs, successors and assigns shall have no legal or equitable rights, interests or claims in any property or assets of the Employer or any Related Employer. For purposes of the payment of benefits under the plan, the assets of the Employer or of any Related Employer shall be, and shall remain, the general, unpledged, unrestricted assets of the Employer or of such Related Employer, respectively. The Employer's obligation under the Plan shall be merely that of an unfunded and unsecured promise to pay money in the future. 10.2 Trusts; Transfers of Assets, Property. Notwithstanding the foregoing, in the event of a Change in Ownership or Control, the Employer shall create an irrevocable Trust, or before such time the Employer may create an irrevocable or revocable Trust, to hold funds to be used in payment of the obligations of the Employer or any Related Employer under the Plan. 10.3 Section 409A. It is intended that the Plan comply with the provisions of Section 409A, so as to prevent the inclusion in gross income of any amounts deferred hereunder in a taxable year that is prior to the taxable year or years in which such amounts would otherwise actually be paid or made available to Participants or Beneficiaries. This Plan shall be construed, administered, and governed in a manner that effects such intent, and the Committee shall not take any action that would be inconsistent with such intent. Each installment payment of compensation under this Plan shall be treated as a separate payment of compensation for purposes of applying Section 409A. Although the Committee shall use its best efforts to avoid the imposition of taxation, interest and penalties under Section 409A of the Code, the tax treatment of deferrals under this Plan is not warranted or guaranteed. Neither the Company, any Employer, the Board, any director, officer, employee and advisor, the Board nor the Committee (or any delegate thereof) shall be held liable for any taxes, interest, penalties or other monetary amounts owed by any Participant, Beneficiary or other taxpayer as a result of the Plan.

The Employer shall have no obligation or liability to a Participant under the Plan except as provided by the Plan and an Election. 10.5 Limitation of Rights. Neither the establishment of the Plan, nor any amendment thereof, nor the creation of any fund or account, nor the payment of any benefits, will be construed as giving to the Participant or any other person any legal or equitable right against the Employer, the Committee or any Related Employer except as provided herein; and in no event will the terms of employment or service of the Participant be modified or in any way affected hereby. 10.6 Anti-Assignment. No right or interest of the eligible employees or retirees under this Plan shall be subject to involuntary alienation, assignment or transfer of any kind. The

{00113938 2 } 19 Employer, the Board, the Committee and any of their delegates shall not review, confirm, guarantee or otherwise comment on the legal validity of any voluntary assignment. 10.7 Facility of Payment. If the Employer determines, on the basis of medical reports or other evidence satisfactory to the Employer, that the recipient of any benefit payments under the Plan is incapable of handling his affairs by reason of minority, illness, infirmity or other incapacity, the Employer may disburse such payments to a person or institution designated by a court which has jurisdiction over such recipient or a person or institution otherwise having the legal authority under State law for the care and control of such recipient. The receipt by such person or institution of any such payments, and any such payment to the extent thereof, shall discharge the liability of the Employer for the payment of benefits hereunder to such recipient. 10.8 Notices. Any notice or other communication required or permitted to be given in connection with the Plan shall be in writing and shall be deemed to have been duly given (i) upon request, if delivered personally or via courier, (ii) upon confirmation of receipt, if given by facsimile or electronic transmission, and (iii) on the third business day following mailing, if mailed first-class, postage prepaid, registered or certified mail as follows: If it is sent to the Employer or Employer, it will be at the address specified by the Employer; or If it is sent to a Participant or Beneficiary, it will be at the last address filed with the Employer by the Participant (or Beneficiary). 10.9 Tax Withholding.

If the Employer concludes that tax is owing with respect to any deferral or payment hereunder, the Employer shall withhold such amounts from any payments due the Participant or his Beneficiary, as permitted by law, or otherwise make appropriate arrangements with the Participant or his Beneficiary for satisfaction of such obligation. Tax, for purposes of this section, means any federal, state, local, foreign or any other governmental income tax, employment or payroll tax, excise tax, or any other tax or assessment owing with respect to amounts deferred, any earnings thereon, and any payments made to Participants or Beneficiaries under the Plan. 10.10 No Guarantee or Employment or Participation. Nothing in the Plan shall interfere with or limit in any way the right of the Employer to terminate any Participant's employment at any time and for any reason, nor confer upon any Participant any right to continue in the employ of the Employer or any Related Employer. No employee of the Employer shall have a right to be selected as a Participant under the Plan or, if selected, to continue to participate for any Plan Year. 10.11 Unclaimed Benefit. Each Participant shall keep the Employer informed of his current address and the current address of his Beneficiary. The Employer shall not be obligated to search for the whereabouts of any person. If the location of a Participant is not made known to the Employer within three years after the date on which payment of the Participant's vested Account is

{00113938 2 } 20 scheduled to be made (or to commence), payment may be made as though the Participant had died at the end of the three-year period. If within one additional year after such three-year period has elapsed, or, within three years after the actual death of a Participant, the Employer is unable to locate the Beneficiary of the Participant, then the Employer shall have no further obligation to pay any benefit hereunder to such Participant or Beneficiary or any other person and such benefit shall be irrevocably forfeited. 10.12 Governing Law. The Plan will be construed, administered and enforced according to the laws of the State of Oklahoma without regard to principles of conflicts of law to the extent not otherwise preempted by the Code or by ERISA. 10.13 Erroneous Payment. Any amount paid under this Plan in error to a Participant or to a Participant's Beneficiary shall be returned to the Employer. A payment made in error does not create on the part of the recipient a legally binding right to such payment. In addition, the Plan and its agents are authorized to (A) recoup overpayments plus any earnings or interest, and (B) if necessary, offset any overpayments that are not returned against other Plan benefits to which the recipient is or becomes entitled.
