The Williams Companies Amended and Restated Retirement Restoration Plan

WHEREAS, The Williams Companies, Inc. and certain of its subsidiaries ("Employers") maintain The Williams Pension Plan ("Pension Plan") for the benefit of eligible employees of the Employers;

WHEREAS, Sections 401(a)(17) and 415 of the Internal Revenue Code (“Code”) establish limitations as to the amount of pension benefit which may be accrued under or payable from the Pension Plan on behalf of any participant therein;

WHEREAS The Williams Companies, Inc. adopted The Williams Companies Retirement Restoration Plan as amended and restated effective January 1, 2005;

WHEREAS The Williams Companies, Inc. now desires to amend The Williams Companies Retirement Restoration Plan to clarify that no hired or rehired employees will become participants in the plan after December 31, 2018 and change the rate of future accruals under the plan;

NOW, THEREFORE, The Williams Companies, Inc. hereby adopts, effective as of January 1, 2024, The Williams Companies Retirement Restoration Plan as amended and restated and set forth hereinafter.

This document is generally effective as of January 1, 2024 (the "Effective Date"). It sets forth the terms of the Plan applicable to deferrals which are subject to Section 409A, i.e., generally, deferred amounts earned or vested after December 31, 2004 (the "409A Program"). Certain

other deferrals under the Plan shall be governed by a separate set of documents which set forth the pre-Section 409A terms of the Plan (the "Pre-409A Program") to the extent such other deferrals and the terms of Pre-409A Program are not incorporated into this document. Together, this document and the documents for the Pre-409A Program describe the terms of a single plan. However, amounts subject to the terms of this 409A Program and amounts subject to the terms of the Pre-409A Program shall be tracked separately at all times. The preservation of the terms of the Pre-409A Program, without material modification, and the separation between the 409A Program amounts and the Pre-409A Program amounts are intended to be sufficient to permit the Pre-409A Program to remain exempt from Section 409A. Subject to the applicable Plan termination provisions, with respect to vested benefits under the Pre-409A Program: (i) in the case of vested Participants on December 31, 2004 who were receiving vested benefits on such date, such benefits shall continue to be paid under the Pre-409A Program at the same time and in the same amounts as specified under the form of payment in effect on such date; and (ii) in the case of vested Participants who were not receiving vested benefits on such date, such benefits shall be paid under the Pre-409A Program at the time and in the form specified in Article IV of The Williams Companies Supplemental Retirement Plan as in effect on December 31, 2004.

In this Plan, unless the context clearly implies otherwise, the singular includes the plural, the masculine includes the feminine, and initially capitalized words have the following meaning:

2.1    Actuarial Equivalent. An amount or benefit of equivalent current value to the amount or benefit which would otherwise have been provided to or on account of a Participant or Beneficiary determined on the basis of the actuarial assumptions then in effect under the Pension

Plan and such other assumptions permitted by Code Section 409A and final regulations promulgated thereunder as may be deemed necessary by an actuary selected by the Company or the Committee.

    2.2    Base Pay. The regular wages and salary of a Participant, which is in excess of Code limitations and which does not include any short term disability paid by an Employer, overriding royalties, amounts paid under a phantom override plan, bonuses (including, but not limited to, bonuses under The Williams Companies, Inc. Executive Incentive Compensation Plan), salary reduction amounts contributed to The Williams Investment Plus Plan, salary reduction amounts contributed to any qualified transportation plan established by an Employer in accordance with Code Section 132(f)(4) or to any cafeteria plan or flexible benefits plan established by an Employer in accordance Section 125 and related sections of the Code, severance pay, cost of living pay, housing pay, relocation pay (including mortgage interest differential) or any such other taxable and non-taxable fringe benefits and extraordinary compensation of any kind.

2.3     Basic Supplemental Benefit. The amount payable to a Vested Participant in the form of a lump sum distribution based upon the amount credited to his Supplemental Pension Account pursuant to the applicable provisions of this Plan.

2.4    Beneficiary. The Surviving Spouse or other person who is entitled to receive benefits pursuant to Article V of this Plan.

    2.5     Benefit Starting Date. With respect to a Supplemental Retirement Benefit, the date shall be the later of the first day of the month following the date the Participant attains age fifty-five (55) or the first day of the month following the expiration of the six (6) month period commencing with the date the Participant incurs a Separation from Service. With respect to a

Death Benefit, the date shall be the first day of the month following the expiration of the three (3) month period commencing with the Participant's date of death. With respect to a Supplemental Disability Benefit, the date shall be the date specified under the provisions of Section 3.5. A benefit payable under the Pre-409A Program, shall be payable as of the date a corresponding benefit is payable under the Pension Plan.

2.6    Board. The Board of Directors of the Company as constituted from time to time.

2.7    Change in Control. The occurrence of (i) a Change in the Ownership of the Company, as defined below, (ii) a Change in Effective Control of the Company, as defined below, or (iii) a Change in the Ownership of a Substantial Portion of the Assets of the Company, as defined below. To qualify as a Change in Control event, the occurrence of the event shall be objectively determinable, strictly ministerial, and shall not involve any discretionary authority by the plan administrator. Code Section 318(a) shall be applied to determine stock ownership for purposes of this section. Substantially vested stock underlying a vested option is considered owned by the person who holds the vested option (and the stock underlying an unvested option is not considered owned by the person who holds an unvested option). To qualify as a Change in Control with respect to a Participant, the Change in Control must relate to (x) the corporation for whom the Participant is performing services at the time of the Change in Control event; (y) the corporation that is liable for the payment of benefits under this Plan (or all corporations which are liable for payment if more than one corporation is liable) but only if either the benefits are attributable to the performance of service by the Participant for such corporation (or corporations) or there is a bona fide business purpose for such corporation (or corporations) to be liable for such payment and, in either case, no significant purpose of making such corporation or corporations liable for such payment is the avoidance of Federal income tax; or (z) a corporation

that is a majority shareholder of a corporation identified in subsections (x) or (y) above, or any corporation in a chain of corporations in which each corporation is a majority shareholder of another corporation in the chain, ending in a corporation identified in subsections (x) or (y) above. The provisions of Treas. Reg. § 1.409A-3, as amended, shall govern with respect to the definition of terms as used therein and in the interpretation of whether a Change in Control has occurred.

    (a)     A "Change in the Ownership of the Company" occurs on the date that any one person or more than one person Acting as a Group, as defined below, acquires ownership of stock of the Company ("Stock") that, together with Stock held by such person or group, constitutes more than fifty percent (50%) of the total fair market value or total voting power of the Stock. However, if any one person or more than one person Acting as a Group, is considered to own more than fifty percent (50%) of the total fair market value or total voting power of the Stock, the acquisition of additional Stock by the same person or persons is not considered to cause a Change in the Ownership of the Company. An increase in the percentage of Stock owned by any one person, or persons Acting as a Group, as a result of a transaction in which the Company acquires its Stock in exchange for property will be treated as an acquisition of Stock for purposes of this subsection. This subsection applies only when there is a transfer of Stock (or issuance of Stock) and Stock remains outstanding after the transaction.

(b)     "Acting as a Group." persons will not be considered to be Acting as a Group solely because they purchase or own Stock at the same time or as a result of the same public offering. However, persons will be considered to be Acting as a Group if they are owners of a corporation that enters into a merger, consolidation, purchase or

acquisition of Stock, or similar business transaction with the Company. If a person owns stock in both corporations that enter into a merger, consolidation, purchase or acquisition of Stock or similar transaction involving another corporation, such shareholder is considered to be Acting as a Group with other shareholders only in such corporation prior to the transaction giving rise to the change and not with respect to the ownership interest in the other corporation.

(c)    A "Change in the Effective Control of the Company" occurs only on either of the following dates: (1) The date that any one person, or more than one person Acting as a Group, acquires (or has acquired during the twelve (12)-month period ending on the date of the most recent acquisition by such person or persons) ownership of the Stock possessing thirty percent (30%) or more of the total voting power of the Stock of the Company; or (2) The date a majority of members of the Board is replaced during any 12-month period by directors whose appointment or election is not endorsed by a majority of the members of the Board before the date of the appointment or election.

    If any one person, or more than one person Acting as a Group, is considered to be in effective control of a Company, the acquisition of additional control of the Company by the same person or persons is not considered to cause a Change in the Effective Control of the Company.

(d)     A "Change in the Ownership of a Substantial Portion of the Assets of the Company" occurs on the date that any one person, or more than one person Acting as a Group, acquires (or has acquired during the twelve (12)-month period ending on the date of the most recent acquisition by such person or persons) assets from the Company that have a total gross fair market value equal to or more than forty percent (40%) of the total

gross fair market value of all assets of the Company immediately prior to such acquisition or acquisitions. For this purpose, the gross fair market value means the value of the assets of the Company or the value of the assets being disposed of, determined without regard to any liabilities associated with such assets. Notwithstanding the foregoing, there is no Change in the Ownership of a Substantial Portion of the Assets of the Company when there is a transfer of assets to an entity that is controlled by the shareholders of the Company immediately after the transfer. A transfer of assets by the Company is not treated as a Change in the Ownership of a Substantial Portion of the Assets of the Company if the assets are transferred to (1) a shareholder of the Company (immediately before the asset transfer) in exchange for or with respect to its Stock; (2) an entity, fifty percent (50%) or more of the total value or voting power of which is owned, directly or indirectly, by the Company; (3) a person, or more than one person Acting as a Group, that owns, directly or indirectly, fifty percent (50%) or more of the total value or voting power of all the outstanding Stock; or (4) an entity, at least fifty percent (50%) of the total value or voting power of which is owned, directly or indirectly, by a person, or more than one person Acting as a Group, that owns, directly or indirectly, fifty percent (50%) or more of the total value or voting power of all the outstanding Stock. For purposes of this subsection (d), and except as otherwise provided, a person's status is determined immediately after the transfer of assets.

2.9    Code Limitations. The limitations on compensation which may be taken into account in determining benefits under and on benefits payable from the Pension Plan imposed by Sections 401(a)(17) and 415 of the Code.

    2.12    Credit Date. (a) With respect to Supplemental Compensation Credits, the last day of the applicable Plan Year referenced in the context in which such term is used, and (b) with respect to Supplemental Interest Credits, the last day of each quarter of each Plan Year.

    2.13    Death Benefit. The benefit provided under Article V of this Plan to the Surviving Spouse or other Beneficiary of a Participant.

    2.14    Disability. A physical or mental condition which (a) satisfies the initial requirements for disability payments under the Employer maintained long-term disability plan, or (b) if no long-term disability plan is maintained by an Employer for such Participant, the presence of a condition that, as of a date designated by the Administrative Committee, totally and permanently prevents the Participant, in the judgment of the Administrative Committee, from engaging in any substantial gainful employment with his Employer, and which (i) did not arise while the Participant was engaged in or as a result of having engaged in a criminal act, (ii) did not result from addiction to narcotics or other drugs, or a self-inflicted injury while sane or insane, and (iii) did not result from voluntary or involuntary service in the armed forces of the United States or any foreign country, which prevents a return to employment with an Employer and for which the person receives a veteran's disability pension. A determination of Disability shall be based on competent medical evidence satisfactory to the Administrative Committee. Disability shall be considered to have ended if, prior to the Normal Retirement Date of a Participant, (a) he engages in any substantial gainful activity, except for such employment as is found by the Administrative Committee to be for the primary purpose of rehabilitation or not

incompatible with a finding of total and permanent disability, or (b) he has sufficiently recovered, in the opinion of the Administrative Committee based on a medical examination by a doctor or clinic appointed by the Administrative Committee, to be able to engage in regular employment with an Employer, or (c) he refuses to undergo any medical examination requested by the Administrative Committee, provided that a medical examination shall not be required more frequently than twice in any calendar year.

2.15    Eligible Employee. Any Employee of an Employer who (a) is a participant in the Pension Plan and (b) holds a position that has been classified as an executive position by the Company's executive compensation department. Employees hired or rehired after December 31, 2018, are not eligible to participate in the Pension Plan. As a result, no Employees hired or rehired after December 31, 2018, are eligible to participate in The Williams Companies Retirement Restoration Plan or become Eligible Employees.

2.16    Employee. An "eligible Employee" as such term is defined under the Pension Plan.

2.17    Employer. An "Employer" as such term is defined under the Pension Plan.

    2.19    Key Employee. An employee designated on an annual basis by the Company as of December 31 (the “Key Employee Designation Date”) as an employee meeting the requirements of Section 416(i) of Code without regard to paragraph (5) thereof utilizing the definition of compensation under Treasury Regulation § 1.415(c)-2(d)(2). A Participant

designated as a “key employee” shall be a “key employee” for the entire twelve (12) month period beginning on April 1 following the Key Employee Designation Date.

The pension benefit which would have been paid during a Plan Year to the Participant or his Beneficiary (including a spouse or other contingent annuitant) pursuant to the benefit formula set forth in Section 2.1 of the Pension Plan which is applicable to such Participant and the method of payment selected by the Participant under the Pension Plan, without taking into account the Code Limitations; but (for any Plan Year beginning on or after January 1, 2002) taking into account only the Supplemental Retirement Compensation of the Participant in lieu of "Compensation" under Section 2.19 of the Pension Plan.

2.22    Participant. An Eligible Employee who agrees to be bound by the terms of this Plan by filing such form or forms, if any, as the Committee may require. Such term includes a Former Participant, a Rule of 55 Participant, a Transitional Participant and a Vested Participant as appropriate in the circumstances in which the term is used in the Plan.

2.23    Pension Plan. The Williams Pension Plan, as in effect on January 1, 2005 and as amended and/or restated from time to time. With respect to a Participant who has a benefit payable under the Williams Inactive Employees Pension Plan, as in effect January 1, 2005 and as amended and/or restated from time to time, such plan is also included within such term. It is anticipated that the Williams Pension Plan and the Williams Inactive Employees Pension Plan will merge effective December 31, 2023 with the Williams Pension Plan being the surviving Plan, such that references to Pension Plan in this document will then refer to the merged plan.

2.24    Pension Plan Benefit. The pension benefit actually paid during a Plan Year to the Participant or his Beneficiary (including a spouse or other contingent annuitant) pursuant to the benefit formula (set forth in Section 2.1 of the Pension Plan) which is applicable to such Participant and the method of payment selected by the Participant under such plan.

    2.26    Plan Interest Rate. The rate of interest applicable under the terms of the Plan for determining Supplemental Interest Credits as of any Credit Date determined as the rate for the month of September immediately preceding the respective Plan Year in which the rate is applicable under the Plan, which rate is based upon the annual rate for 30-year Treasury securities as specified by the Commissioner of Internal Revenue in revenue rulings, notices and other guidance published in the Internal Revenue Bulletin.

2.27    Plan Year. Each twelve (12) consecutive month fiscal year beginning January 1 and ending December 31.

2.29    Separation from Service. The Participant’s termination or deemed termination from employment with the Company and its Affiliates. For purposes of determining whether a

separation from service has occurred, the employment relationship is treated as continuing intact while the Participant is on military leave, sick leave or other bona fide leave of absence if the period of such leave does not exceed six (6) months, or if longer, so long as the Participant retains a right to reemployment with his or her employer under an applicable statute or by contract. For this purpose, a leave of absence constitutes a bona fide leave of absence only if there is a reasonable expectation that the Participant will return to perform services for his or her employer. If the period of leave exceeds six (6) months and the Participant does not retain a right to reemployment under an applicable statute or by contract, the employment relationship will be deemed to terminate on the first date immediately following such six (6) month period. Notwithstanding the foregoing, if a leave of absence is due to any medically determinable physical or mental impairment that can be expected to result in death or can be expected to last for a continuous period of not less than six (6) months, and such impairment causes the Participant to be unable to perform the duties of the Participant’s position of employment or any substantially similar position of employment, a twenty-nine (29) month period of absence shall be substituted for such six (6) month period. For purposes of this Section 2.29, a separation from service occurs at the date as of which the facts and circumstances indicate either that, after such date: (A) the Participant and the Company reasonably anticipate the Participant will perform no further services for the Company and its Affiliates (whether as an employee or an independent contractor), or (B) that the level of bona fide services the Participant will perform for the Company and its Affiliates (whether as an employee or independent contractor) will permanently decrease to no more than twenty (20%) of the average level of bona fide services performed over the immediately preceding thirty-six (36) month period or, if the Participant has been providing services to the Company and its Affiliates for less than thirty-six (36) months, the full period

over which the Participant has rendered services, whether as an employee or independent contractor. The determination of whether a separation from service has occurred shall be governed by the provisions of Treasury Regulation § 1.409A-1, as amended, taking into account the objective facts and circumstances with respect to the level of bona fide services performed by the Participant after a certain date.

    2.30    Service Participant. A Vested Participant who is a "Service Participant" as such term is defined under the Pension Plan.

    2.31    Supplemental Compensation Credit. The amount deemed credited to a Participant’s Supplemental Pension Account based upon his Supplemental Retirement Compensation for a Plan Year (or any part of a Plan Year and for a disabled Participant accruing Benefit Service credit or Compensation Credit pursuant to Section 5.3 of the Pension Plan, based upon his rate of Supplemental Retirement Compensation as of the date his Disability commenced), with such amount deemed to be credited as of the Credit Date for such Plan Year and determined in accordance with the following:

1.13% on Compensation greater than 170 percent of the Wage Base. For Plan Years beginning on or after January 1, 2008, the rate is 1.20% on Compensation above the Wage Base.

    2.32    Supplemental Interest Credit. The amount deemed credited to a Participant's Supplemental Pension Account based upon the balance in his Supplemental Pension Account on the Credit Date in a Plan Year (prior to the inclusion of the Supplemental Compensation Credit, if any, for such Plan Year) multiplied by the Plan Interest Rate applicable for such Plan Year.

    2.33    Supplemental Pension Account. A hypothetical account maintained for recordkeeping purposes only on behalf of a Participant to record the amount which would have accumulated if contributions had been made for each Plan Year of such Participant's active participation equal to his Supplemental Compensation Credit and if such contributions and Supplemental Interest Credits had accumulated with interest at the applicable Plan Interest Rate until his Benefit Starting Date.

For purposes of determining an "Accrued Benefit" under the Pension Plan, if a Participant is credited with less than two thousand eighty (2,080) "Hours of Service" under the Pension Plan for determining "Benefit Service" under the Pension Plan during a Plan Year, his Supplemental Retirement Compensation for that Plan Year shall be the product of his actual Supplemental Retirement Compensation for such Plan Year as described above multiplied by a fraction the numerator of which is two thousand eighty (2,080) and the denominator of which is the number of "Hours of Service" under the Pension Plan with which he is credited for such Plan Year.

2.36    Supplemental Survivor Pension. An amount payable to (i) the Surviving Spouse or Beneficiary of a Vested Participant, (ii) in accordance with Section 5.1, the Surviving Spouse of a Transitional Participant, or (iii) in accordance with Section 5.2, the Beneficiary of a Transitional Participant who died prior to the Benefit Starting Date of his Supplemental Retirement Benefit in a lump sum distribution determined by the balance of such Participant's Supplemental Pension Account at the date the amount of such distribution is determined.

3.2    Restoration of Credited Service for a Transitional Participant. Following the recommencement of employment with an Employer by a Transitional Participant whose

employment with an Employer was terminated at a time when such Transitional Participant had a Supplemental Retirement Benefit and whose benefit had commenced to be paid, such Transitional Participant's subsequent Supplemental Retirement Benefit shall be reduced, but not below zero, by an amount which is the Actuarial Equivalent of the amount of Supplemental Retirement Benefit previously paid. If the Transitional Participant does not have a subsequent Supplemental Retirement Benefit, then the Transitional Participant shall not be required to reimburse this Plan with respect to any portion of the Supplemental Retirement Benefit previously paid to such Transitional Participant.

3.3    Cash Balance Supplemental Retirement Benefit for a Vested Participant. A Vested Participant's cash balance Supplemental Retirement Benefit shall be the amount credited to the Vested Participant's Supplemental Pension Account upon his Benefit Starting Date.

3.4    Cash Balance Supplemental Early Retirement Benefit. Solely with respect to a Rule of 55 Participant who incurs a Separation from Service with an Employer on or after age fifty-five (55), the amount credited to the Participant's Supplemental Pension Account shall be multiplied by the applicable percentage in the following schedule and any amount in excess of 100% of the Supplemental Pension Account shall be paid on the Benefit Starting Date.

The death benefit payable commencing on the Benefit Starting Date shall be the Actuarial Equivalent of the difference between the Surviving Spouse's pension payable for the life of the spouse under the Pension Plan and the Surviving Spouse's pension which would have been paid based upon such Participant's Normalized Pension Benefit. Provided, however, in the event Supplemental Survivor Pension coverage has not been waived and the Supplemental Survivor Pension amount payable to the Surviving Spouse is greater than the Actuarial Equivalent death benefit amount determined pursuant to this Section 5.1, such greater amount shall be payable in accordance with Section 5.2 and no amount shall be payable pursuant to this Section 5.1.

Spouse shall receive a Supplemental Survivor Pension with payments commencing on the Benefit Starting Date.

(e)    To determine all benefits and resolve all questions pertaining to the administration and interpretation of the Plan provisions, either by rules of general applicability or by particular decisions. To the maximum extent permitted by law, all interpretations of the Plan and other decisions of the Committee shall be conclusive and binding on all parties.

(f)    To adopt such forms, rules and regulations as it shall deem necessary or appropriate for the administration of the Plan and the conduct of its affairs, provided that

any such forms, rules and regulations shall not be inconsistent with the provisions of the Plan.

(g)    To remedy any inequity resulting from incorrect information received or communicated or from administrative error.

(h)    To commence or defend any litigation arising from the operation of the Plan in any legal or administrative proceeding.

6.4    Required Information. Any Participant or Former Participant and any Beneficiary eligible to receive benefits under the Plan shall furnish to the Committee any information or proof requested by the Committee and reasonably required for the proper administration of the Plan. Failure on the part of the Participant, Former Participant or Beneficiary to comply with any such request within a reasonable period of time shall be sufficient grounds for delay in the payment of benefits under the Plan until such information or proof is received by the Committee.

6.5    Compensation and Expenses. All expenses incident to the operation and administration of the Plan reasonably incurred, including, without limitation by way of specification, the fees and expenses of attorneys and advisors, and for such other professional, technical and clerical assistance as may be required, shall be paid by the Employers. Members of the Committee shall not be entitled to any compensation by virtue of their services as such nor be required to give any bond or other security; provided, however, that they shall be entitled to reimbursement by the Employers for all reasonable expenses which they may incur in the performance of their duties hereunder and in taking such action as they deem advisable hereunder within the limits of the authority given them by the Plan and by law.

6.6    Indemnification. To the extent provided for in the Company by-laws, each Employer shall indemnify and hold harmless each member of the Board, each member of the

Committee, and each officer and employee of an Employer to whom are delegated duties, responsibilities, and authority with respect to this Plan against all claims, liabilities, fines and penalties, and all expenses reasonably incurred by or imposed upon him (including but not limited to reasonable attorney fees) which arise as a result of his actions or failure to act in connection with the operation and administration of this 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 an Employer. Notwithstanding the foregoing, an 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.

6.7    Claims Procedure. The Committee as constituted and serving from time to time shall adopt, and may change from time to time, claims procedures, provided that such claims procedures and changes thereof shall conform with Section 503 of the Employee Retirement Income Security Act of 1974, as amended, and regulations promulgated thereunder. Such claims procedures, as in effect from time to time shall be deemed to be incorporated herein and made a part hereof.

7.1    Benefits Payable by the Employers. All benefits payable under this Plan shall constitute an unfunded obligation of the Employers. Payments shall be made, as due, from the general funds of the Employers. The Employers, at their option, may maintain one or more bookkeeping reserve accounts to reflect their obligations under the Plan and may make such investments as they, or any of them, may deem desirable to assist in meeting such obligations.

Any such investments shall be assets of the Employers subject to claims of general creditors. No person eligible for a benefit under this Plan shall have any right, title or interest in any such investments.

7.2    Amendment or Termination.     The Committee is authorized to amend the Plan, if such amendment does not increase the costs of the Plan and the Board is authorized to amend, modify, restate or terminate the Plan; provided, however, that (i) no such action by the Committee or the Board shall reduce a Participant's Supplemental Retirement Benefit accrued as of the time thereof, and (ii) any such amendments, modifications, restatement or termination shall be effectuated in a manner which will not result in the imposition of Code Section 409A penalties. Payments under the 409A Program may be accelerated only to the extent permitted by Treas. Reg. 1.409A-3(j)(4). In this regard, if a Change in Control occurs the service recipient entity that will be primarily liable immediately after the Change in Control transaction for the payment of benefits under the 409A Program shall terminate the 409A Program and all other nonaccount plans which are aggregated with the 409A Program under Treas. Reg. 1-409A-3(j)(4)(ix). The date of such termination shall be the first business day following such Change in Control and all amounts held in the Plan for any Participant shall be distributed in a lump sum within ten (10) business days after such termination. Generally, the amendment or termination of the Pre-409A Program shall be effectuated in a manner which either (A) avoids causing the "Grandfathered Benefits" to be materially modified within the meaning of Treas. Reg. 1.409A-6(a)(4); or (B) causes the Pre-409A Program to meet the requirements of Code Section 409A without the imposition of Code Section 409A penalties. In this regard, upon termination of the 409A Program due to a Change in Control, the Pre-409A Program shall be terminated either pursuant to Treas. Reg. 1.409A-6(a)(4)(iii), or pursuant to a plan termination

amendment which causes the Pre-409A Program to comply with Code Section 409A. The date of such termination shall be the first business day following such Change in Control and all amounts held in the Plan for any Participant shall be distributed in a lump sum within ten (10) business days after such termination.

7.3    Status of Employment. Nothing herein contained shall be deemed: (a) to give to any Participant the right to be retained in the employ of any Employer, subsidiary or affiliate; (b) to affect the right of any Employer to discipline or discharge any Participant at any time; (c) to give any Employer, subsidiary or affiliate the right to require any Participant to remain in its employ; or (d) to affect any Participant's right to terminate his or her employment at any time.

7.4    Payments to Minors and Incompetents. If a Participant, Former Participant or Beneficiary entitled to receive any benefits hereunder is a minor or is deemed by the Committee or is adjudged to be legally incapable of giving a valid receipt and discharge for such benefits, they will be paid to the duly appointed guardian of such minor or incompetent or to such other person or entity as the Committee may designate. Such payment shall, to the extent made, be deemed a complete discharge of any liability for such payment under the Plan.

7.5    Inalienability of Benefits. The right of any person to any benefit or payment under the Plan shall not be subject to voluntary or involuntary transfer, alienation or assignment, and, to the fullest extent permitted by law, shall not be subject to attachment, execution, garnishment, sequestration or other legal or equitable process. In the event a person who is receiving or is entitled to receive benefits under the Plan attempts to assign, transfer or dispose of such right, or if an attempt is made to subject said right to such process, such assignment, transfer or disposition shall be null and void.

7.6    Qualified Domestic Relations Orders. If a qualified domestic relations order is applicable to a Participant's Pension Plan Benefit, such Participant's Pension Plan Benefit shall be deemed to be the amount which would have otherwise been payable to the Participant from the Pension Plan if such qualified domestic relations order never existed.

7.7    Governing Law. Except to the extent preempted by federal law, the Plan shall be governed by and construed in accordance with the laws of the State of Oklahoma.

7.8    Procedure for Adoption. Any corporation which is a contributing employer under the Pension Plan may, by resolution of such corporation's board of directors, adopt the Plan subject to such terms and conditions as may be required by the Committee consistent with the provisions of the Plan.
