Western Midstream Partners, LP Executive Change in Control Severance Plan

From time to time, the Company may explore potential transactions that could result in a Change in Control. The Company believes that, when a Change in Control occurs or is perceived as imminent, the Company should be able to rely on its executives to serve the best interests of the Company and its equityholders, without concern that its executives might be distracted by the personal uncertainties and risks that may be created by a Change in Control or the perception of an imminent Change in Control.

The Company also believes that it is consistent with its employment desires and in the best interests of the Company and its equityholders to provide severance compensation for its eligible executives in the event of a qualifying termination of employment following a Change in Control.

Accordingly, to assure the Company of its executives’ continued attention and dedication and to seek to ensure the availability of their continued service, notwithstanding the possibility or occurrence of a Change in Control, the Plan was adopted effective as of the Effective Date.

provided that any individual performance goals that are not based on objective financial performance criteria shall be deemed earned at target; provided, further, that if the individual award agreement between the Company and the Participant or other contract applicable to any long-term incentive award held by the Participant provides for more favorable vesting treatment than provided in the Plan, then the more favorable treatment shall apply to such award;

In order to receive any of the payments and benefits outlined in this Section 3.02, the Participant must execute, deliver, and not revoke a separation agreement containing an effective waiver and release of all claims against the Company, its Affiliates and their respective representatives, and certain other persons and entities, and containing other provisions in the form required by the Plan Administrator (the “Release Agreement”) that becomes irrevocable in accordance with its terms within 55 days following the Date of Termination (or, if applicable in the case of Section 3.02(b), following the consummation of the Change in Control) (the “Release Condition”). The Plan Administrator, composed of such members serving as of a date prior to the Change in Control, may, in its discretion, require that the Release Agreement a Participant must execute and not revoke in satisfaction of the Release Condition include restrictive covenants in favor of the Company and its Affiliates (which may include a perpetual non-disclosure of confidential information provision, a non-disparagement provision, non-competition and employee, customer, prospective customer, supplier and vendor non-solicitation provisions, in each case that are effective from the date of Participant’s termination of employment and for no greater than 18 months thereafter and, with respect to the non-competition provision, that restrict the Participant from engaging in any Restricted Business during such period) in substantially the form attached hereto

as Exhibit A; provided, however, the Plan Administrator may update the form of Release Agreement attached hereto, in its sole discretion, provided that such update is determined and communicated to the affected Participant at least 10 business days prior to the date of such Change in Control. If a Participant does not satisfy the Release Condition, the only payment under the Plan to which the Participant would be entitled is the payment for accrued vacation set forth in Section 3.02(a)(vi).

SECTION 3.03. Other Benefits Payable and Offset.

a.    Accrued Benefits. The Separation Benefits shall be payable in addition to, and not in lieu of, other accrued or vested or earned but deferred compensation, rights, options or other benefits that are owed to a Participant upon or following his or her termination of employment, including accrued amounts or benefits previously earned and payable under any bonus or other compensation plans, stock option plan, equity ownership plan, equity purchase plan, life insurance plan, health plan, disability plan or similar or successor plan, and any business expenses required to be reimbursed under the applicable policies of the Company or any Subsidiary or any Affiliate.

b.    Offsets. Notwithstanding the foregoing, any Separation Benefits paid under the Plan will be reduced, on a dollar-for-dollar basis, by the following, and such reduction shall be made without any change to the timing of payment in a manner that would violate Section 409A of the Code:

i.    any payments made or to be made to the Participant to comply with, or satisfy liability under, the WARN Act requiring payments in connection with an involuntary termination of employment, plant shutdown or workforce reduction, including amounts paid in connection with paid leaves of absence, back pay, benefits and other payments intended to satisfy such liability or alleged liability; and

ii.    any payment provided to Participant after the Date of Termination that Participant was not legally entitled to receive (e.g., salary continuation for a short period of time following the Date of Termination).

c.    No Duplicative Benefits. In the event that monetary or nonmonetary severance and benefits are due from other severance plan, program or agreement (“Other Source”), then the Plan Administrator will compare such severance and benefits to the severance and benefits due under the Plan and, where the severance and benefits are of the same nature or class, the Participant will be provided with the severance and benefits from the Other Source if such severance and benefits are, in the aggregate, greater than the severance and benefits provided under this Plan; provided, however, under no circumstances shall the Participant receive duplicate severance and benefits as determined by the Plan Administrator, with the result being that the Participant receives, in the aggregate, no less favorable severance and benefits than those due under the Plan. If the Participant is eligible to receive severance and benefits from any Other Source, the form and timing of payments under such Other Source will be determined as set forth by such Other Source, and the form and timing of any remaining severance and benefits payable under the Plan will be as described herein without any change in the timing of payment that would violate Section 409A of the Code. Further, except to the extent explicitly contemplated in Section 3.02(b), benefits under the Plan due as a result of a termination of employment by the Company without Cause or by the Participant with Good Reason within the Protection Period shall be in lieu of benefits under the Western Midstream Partners, LP Executive Severance Plan.

SECTION 3.04. Payment Obligations Absolute. In no event shall a Participant be obligated to seek other employment or take any other action by way of mitigation of the amounts payable to a Participant under any of the provisions of the Plan, nor shall the amount of any payment hereunder be reduced by any compensation earned by a Participant as a result of employment by another employer. Upon a Change in Control, the obligations of the Company and the Subsidiaries and Affiliates to pay the Separation Benefits as required by the Plan shall be absolute and unconditional and shall not be affected by any circumstances, including any set-off, counterclaim,

recoupment, defense or other right that the Company or any Subsidiary or Affiliate may have against any Participant.

SECTION 4.01. Tax Withholding; No Guarantee of Tax Consequences. The Company and its Subsidiaries and Affiliates shall have the power to deduct or withhold, or require the Participant to remit to the Company or its Subsidiaries or Affiliates, any amount deemed sufficient to satisfy U.S. Federal, state, local and non-U.S. taxes, as deemed necessary or appropriate by the Company or its Subsidiaries or Affiliates. No representation, commitment or guarantee is made that any amounts paid under the Plan will be excludable from the recipient’s gross income for any tax purpose, or that any other tax treatment will apply or be available to such Person.

SECTION 4.02. Six-Month Delay for Specified Employee. Notwithstanding any other provision to the contrary, if any Participant is a Specified Employee, no payments under the Plan that constitute nonqualified deferred compensation subject to Section 409A of the Code shall be made to such Participant prior to the date that is six months after the Date of Termination, or such earlier date upon which such amount can be paid or provided under Section 409A of the Code without being subject to additional taxes thereunder. Following any applicable six-month delay, all such delayed payments will be paid in a single lump sum on the earliest date permitted under Section 409A of the Code that is also a business day.

SECTION 4.03. Cutback of Parachute Payments.

a.    Notwithstanding any other provision to the contrary, if a Participant is a “disqualified individual” (as defined in Section 280G of the Code) and any portion of the Separation Benefits or other payments and benefits the Participant is entitled to receive, has received or would receive in connection with a “change in ownership or control” as defined in Section 280G of the Code (a “Section 280G Transaction”) (such payments and benefits, collectively, the “Payments”) would constitute a “parachute payment” (as defined in Section 280G of the Code), then the Payments shall be either (i) reduced (but not below zero) so that the aggregate present value of the Payments will be one dollar ($1.00) less than three times such Participant’s “base amount” (as defined in Section 280G of the Code), such that no portion of the Payments shall be subject to the excise tax imposed by Section 4999 of the Code; or (ii) paid in full, whichever produces the better net after-tax result for such Participant (taking into account any applicable excise tax under Section 4999 of the Code and any other applicable tax).

b.    The reduction of the Payments, if any, shall be made by reducing the Payments in the reverse order in which the Payments would be paid or provided (beginning with such payment or benefit that would be made last in time and continuing, to the extent necessary, through to such payment or benefit that would be made first in time), with any benefits exempt from Section 409A of the Code reduced first.

c.    All determinations as to the Payments to be reduced and the amount of reduction shall be made by a nationally recognized certified public accounting firm selected by the Company (the “Accountant”), whose determination shall be conclusive and binding. It is expressly understood that in determining the amount of any reduction to the Payments, the Accountant shall conduct a “reasonable compensation” analysis under Section 280G of the Code, including a valuation of any applicable noncompetition or other covenant, and the Company and the Participant shall cooperate in good faith in connection with such valuation. All such determinations by the Accountant shall be at the Company’s expense.

d.    If the Accountant, based on controlling precedent or substantial authority, determines that a Payment has been made or provided and, through error or otherwise, that Payment, when aggregated with other Payments used in determining if a “parachute payment” exists, exceeds one dollar ($1.00) less than three times the applicable Participant’s base amount, the Participant shall immediately repay such excess to the Company upon notification that an overpayment has been made. If the Accountant, based on controlling precedent or substantial

authority, determines that a Payment has been reduced pursuant to this Section 4.03 that could have been fully paid or distributed, the Company (or applicable payor) shall promptly pay such amount to the Participant, together with interest at the applicable federal rate provided for in Section 7872(f)(2)(A) of the Code.

SECTION 4.04. Section 409A Considerations. Payments and benefits under the Plan are intended to be exempt from (to the maximum extent possible) or compliant with Section 409A of the Code, and the Company shall interpret and administer the Plan in accordance therewith. The Company may make amendments to the Plan or revise the timing of any payments to be made hereunder in accordance with Section 409A of the Code. Each payment made under the Plan (including each separate installment payment in the case of a series of installment payments) shall be deemed to be a separate payment for purposes of Section 409A of the Code. To the extent any payment subject to the Release Condition is payable during a specified period that spans two taxable years, then to the extent such payment is deemed to constitute nonqualified deferred compensation subject to Section 409A of the Code, such payment shall be made in the second taxable year. To the extent that any of the payments or benefits provided for under the Plan are deemed to constitute nonqualified deferred compensation benefits subject to Section 409A of the Code, references to “termination of employment”, “termination”, or words and phrases of similar import shall be deemed to refer to “separation from service” as defined in Section 409A of the Code, and shall be interpreted and applied in a manner that is consistent with the requirements of Section 409A of the Code. To the extent that any payments or benefits provided for under the Plan are deemed to be a substitute for nonqualified deferred compensation subject to Section 409A of the Code, then the payments and benefits payable hereunder shall be paid at the same time and in the same form as such substituted benefits and payments to the extent required to comply with Section 409A of the Code. To the extent that any reimbursements under the Plan are taxable to a Participant, any such reimbursement payment due to the Participant shall be paid to the Participant as promptly as practicable consistent with the Company’s practice following the Participant’s appropriate itemization and substantiation of expenses incurred, and in all events on or before the last day of the Participant’s taxable year following the taxable year in which the related expense was incurred. The in-kind benefits and reimbursements under the Plan are not subject to liquidation or exchange for another benefit, and the amount of such benefits or reimbursements that a Participant receives in one taxable year shall not affect the amount of such benefits or reimbursements that the Participant receives in any other taxable year. The Continued Benefits are intended to be provided in a manner that is intended to satisfy an exception to Section 409A of the Code, and therefore not be treated as an arrangement providing for nonqualified deferred compensation that is subject to taxation under Section 409A of the Code, or in a manner that otherwise complies with Section 409A of the Code, including (a) providing for the reimbursement of medical expenses incurred during the time period for which the Participant would be entitled to continuation coverage under a group health plan of the Company under COBRA or (b) providing that such benefits constitute the reimbursement or provision of in-kind benefits payable at a specified time or pursuant to a fixed schedule as permitted under Section 409A of the Code and the authoritative guidance thereunder.

The Plan shall bind any successor of the Company, its assets or its businesses (whether direct or indirect, by purchase, merger, consolidation or otherwise), in the same manner and to the same extent that the Company would be obligated under the Plan if no succession had taken place.

In the case of any transaction in which a successor would not by the foregoing provision or by operation of law be bound by the Plan, the Company, as a condition precedent to such transaction, shall require such successor expressly and unconditionally to assume and agree to perform the Company’s obligations under the Plan, in the same manner and to the same extent that the Company would be required to perform if no such succession had taken place.

SECTION 6.01. Amendment and Termination. The Company expects the Plan to be permanent, but since future conditions affecting the Company or its Subsidiaries and its Affiliates cannot be anticipated or foreseen, the Board must necessarily and does hereby reserve the right to amend, modify or terminate the Plan at any time by action of the Plan Administrator; provided, however, that in connection with, in anticipation of or at any time following a Change in Control, the Plan may not be amended, modified or terminated in any manner that would adversely affect the rights or potential rights of any Participant, without the Participant’s written consent.

SECTION 6.02. Board Approval. Any amendment, suspension, discontinuation or termination of the Plan shall be approved by the Board.

SECTION 7.01. Employment Status. This Plan does not constitute a contract of employment or impose on any Participant, the Company or any Subsidiary or Affiliate any obligation to retain the Participant as an Employee, to change the status of the Participant’s employment, or to change the policies of the Company or any Subsidiary or Affiliate regarding termination of employment. Nothing contained in the Plan will be construed as (a) an employment contract between the Company or any Subsidiary or Affiliate and any Employee; (b) a right of any Employee to be continued in the employment of the Company or its Subsidiaries or Affiliates; or (c) a limitation of the right of the Company or its Subsidiaries or Affiliates to discharge any Employee, with or without Cause, at any time. All Employees will be subject to discharge to the same extent as if the Plan had never been adopted.

SECTION 7.02. Special Compensation. Except as otherwise required by law or as specifically provided in any plan or program maintained by the Company, no payment under the Plan shall be included or taken into account in determining any benefit under any pension, thrift, profit sharing, group insurance, or other benefit plan maintained by the Company.

SECTION 7.03. Sources of Payment. The benefits provided under the Plan will be paid from the general assets of the Company and its Subsidiaries and Affiliates in accordance with the terms and provisions of the Plan. Nothing herein will be construed to require the Company or any Subsidiaries or Affiliate to maintain any trust, fund, or otherwise segregate any amount for the benefit of any Person. Furthermore, no Person with a claim for Separation Benefits hereunder will have any claim against, right to, security or other interest in, any fund, account, or assets of the Company or any Subsidiary or Affiliate.

SECTION 7.04. Non-Alienation. No payments, benefits or rights hereunder shall be subject to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, attachment, garnishment, charge, execution or levy of any kind, either voluntary or involuntary, by creditors of any Employee or any Employee’s beneficiary. Any attempt to anticipate, alienate, sell, transfer, assign, pledge, encumber, attach, garnish, charge, execute or levy any payments, benefits or rights hereunder will be void and without effect.

SECTION 7.05. Beneficiary. If a Participant is entitled to receive Separation Benefits but dies prior to receiving entire payment of his Separation Benefits, the Participant’s remaining Separation Benefits shall be paid in accordance with the Participant’s beneficiary designation in accordance with the payment timing provisions set forth in Article III.

SECTION 7.06. Severability. Any provision in the Plan that is prohibited or unenforceable in any jurisdiction by reason of applicable law shall, as to such jurisdiction, be ineffective only to the extent of such prohibition or unenforceability without invalidating or affecting the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

SECTION 7.07. Governing Law. The terms, conditions and provisions of the Plan will be construed, governed and enforced under the laws of Delaware, without regard to its conflicts of law provisions, except as may be preempted by ERISA or other controlling U.S. Federal law. The Plan is intended to be a “top hat” plan for purposes of ERISA, and shall be construed accordingly.

SECTION 8.01. Administration. The Plan Administrator shall have all powers necessary or proper to administer the Plan and to discharge its duties hereunder, and shall have authority to interpret the Plan, apply the provisions hereof, determine eligibility and make all other determinations necessary for the administration of the Plan. The Plan Administrator may establish such rules and procedures as may be necessary to enable it to discharge its duties hereunder. The Plan Administrator may allocate to others certain aspects of the management, operation and responsibilities of the Plan, including the employment of advisors and the delegation of any ministerial duties or functions, to qualified individuals or entities. In writing, or by custom, practice or in operation, the Plan Administrator may provide for the allocation or delegation of any of its duties hereunder to any Person. The Plan Administrator or its designee will also be authorized to engage or employ agents, attorneys, accountants, consultants, and other advisors which it deems to be necessary or appropriate to assist in discharging its duties hereunder.

SECTION 8.02. Claims Procedures. Generally, an employee who is eligible to receive benefits under the Plan does not have to file a claim for such benefits. If a claimant believes that he or she did not receive a benefit to which he or she is entitled, the claimant may file a written claim with the Plan Administrator at the following address stating all of the facts on which the claim is based:

9950 Woodloch Forest

Suite 9800

Within 60 days following receipt of the claim, the Plan Administrator will:

•request any additional information needed to make a decision regarding the claim;

•pay benefits provided by the Plan; or

•send notification to the Claimant of a decision to deny the claim in whole or in part.

If additional information is requested or required in order to make a decision regarding a claim, the claimant will have 60 days from the date the claimant receives such a request to provide the information. The Plan Administrator’s decision to pay benefits or deny a claim in whole or in part will be postponed to allow the claimant to respond to the request. If the claimant does not provide the information within 60 days after the claimant receives the request, the claim will be denied unless the claimant has requested and been granted additional time to provide the information.

If the Plan Administrator denies a claim in whole or in part, the claimant will receive written notice of the denial within 60 days from the date any requested additional information was received. The notice will provide the following:

•the specific reasons for the denial of the claim (including the facts upon which the denial is based) and reference to any pertinent Plan provisions on which the denial is based;

•if applicable, a description of any additional material or information necessary for the claimant to perfect the claim and an explanation of why such material is necessary; and

•an explanation of the claims review appeal procedure including the name and address of the Person or committee to whom an appeal should be directed.

Within 60 days after the claimant receives the notice of denial from the Plan Administrator, the claimant may request a review of the claim by the Plan Administrator. The request must be in writing and must state the reason or reasons why the claimant believes the claim should not have been denied. The claimant should also include with the written request for an appeal any and all documents, materials, or other evidence which he or she believes supports the claim for benefits. The request should be addressed to the Plan Administrator at the address of the Plan Administrator.

Generally, the Plan Administrator will give the claimant written notice of its decision within 60 days of the date the claimant’s request for review was received by the Plan Administrator. However, if the Plan Administrator finds that special circumstances exist, its decision may be given to the claimant more than 60 days after the date the claimant’s request was received, but not later than 120 days after such date. The Plan Administrator’s notice of its decision will include specific reasons for its decision and specific references to the provisions of the Plan on which its decision is based. The decision of the Plan Administrator shall be final, conclusive and binding on all Persons (including Employees, Participants and beneficiaries).

Prior to authorizing and awarding any Separation Benefits hereunder, the Plan Administrator may require the claimant to provide additional information, and to complete any required or requested releases, forms or other documents hereunder, including filing of all claims and requests for payment from any other source.

SECTION 8.03. Legal Proceedings. Any claims and disputes between or among any Persons arising out of or in any way connected with this Plan shall be solely and finally settled by Plan Administrator, acting in good faith, the determination of which shall be final. Unless prohibited by applicable law, no legal action may be commenced prior to the completion of the benefits claims procedure described in the Plan. In addition, no legal action may be commenced after the later of 180 days after receiving a written response of the Plan Administrator to an appeal or 365 days after the date the claimant was terminated. If any such judicial proceeding is undertaken, the evidence presented shall be strictly limited to the evidence timely presented to the Plan Administrator.
