## Exhibit 4.5

**EXHIBIT 4.5**

**FIRST AMENDMENT TO THE**

**WESTERN MIDSTREAM PARTNERS, LP**

**2021 LONG TERM INCENTIVE PLAN**

This FIRST AMENDMENT (the "***First Amendment***") to the Western Midstream Partners, LP 2021 Long Term Incentive Plan, as amended from time to time (the "***Plan***"), is adopted by Western Midstream Holdings, LLC, a Delaware limited liability company (the "***Company***") and general partner of Western Midstream Partners, LP (the "***Partnership***")*.* 

**<u>WITNESSETH:</u>**

**WHEREAS**, on October 15, 2025, the Partnership completed a merger of Aris Water Solutions, Inc. (the "***Aris***") with a subsidiary of the Partnership, whereby Aris became a wholly-owned subsidiary of the Partnership (the "***Merger***");

**WHEREAS**, in connection with the Merger, all authorized but unused shares that were previously approved for issuance pursuant to the Aris Water Solutions, Inc. 2021 Equity Incentive Plan (the "***Aris Shares***"), will be adjusted using the applicable exchange ratio for the Merger, and then assumed by the Company to be added to the common unit pool available under the Plan ("the ***Additional Units***");

**WHEREAS**, Section 7(a) of the Plan provides that the Company's board of directors (the "***Board***") or Committee (as defined under the Plan) may amend the Plan under certain circumstances; and

**WHEREAS,** the Board has determined that it is desirable to amend the Plan to reflect the addition of the Additional Units to the Plan.

**NOW, THEREFORE, BE IT RESOLVED,** effective immediately following the closing of the Merger (the "***Effective Date***"), that Section 4(a) of the Plan shall be amended and restated in its entirety as follows:

Subject to adjustment as provided in Section 4(c), the total aggregate number of Units that may be delivered with respect to Awards under the Plan is 14,403,998. Units withheld from an Award or surrendered by a Participant to satisfy the Company's, Partnership's or an Affiliate's tax withholding obligations (including the withholding of Units with respect to Restricted Units) or to satisfy the payment of any exercise price with respect to the Award shall not be considered to be Units delivered under the Plan for this purpose. If any Award is forfeited, cancelled, exercised, settled in cash, or otherwise terminates or expires without the actual delivery of Units pursuant to such Award (the grant of Restricted Units is not a delivery of Units for this purpose), the Units subject to such Award shall again be available for Awards under the Plan (including Units not delivered in connection with the exercise of an Option or Unit Appreciation Right). There shall not be any limitation on the number of Awards that may be granted and paid in cash.

------

**RESOLVED FURTHER,** that except as provided above, the Plan shall continue to read in the current state.

Ladies and Gentlemen:

&nbsp;&nbsp;&nbsp;&nbsp;We have acted as counsel for Western Midstream Partners, LP, a Delaware limited partnership (the "Partnership"), in connection with the Partnership's registration under the Securities Act of 1933, as amended (the "Act"), of the offer and sale of an additional 4,903,998 of the Partnership's common units, which represent limited partner interests (the "Common Units"), pursuant to the Partnership's registration statement on Form S-8 (the "Registration Statement") to be filed with the Securities and Exchange Commission on October 15, 2025, which Common Units may be issued from time to time in accordance with the terms of the Western Midstream Partners, LP 2021 Long Term Incentive Plan (as amended from time to time, the "Plan").

In reaching the opinions set forth herein, we have examined and are familiar with originals or copies, certified or otherwise identified to our satisfaction, of such documents and records of the Partnership and such statutes, regulations and other instruments as we deemed necessary or advisable for purposes of this opinion, including (i) the Registration Statement, (ii) certain resolutions adopted by the board of directors of Western Midstream Holdings, LLC, the general partner of the Partnership, (iii) the Plan, and (iv) such other certificates, instruments, and documents as we have considered necessary for purposes of this opinion letter. As to any facts material to our opinions, we have made no independent investigation or verification of such facts and have relied, to the extent that we deem such reliance proper, upon certificates of public officials and officers or other representatives of the Partnership.

We have assumed (i) the legal capacity of all natural persons, (ii) the genuineness of all signatures, (iii) the authority of all persons signing all documents submitted to us on behalf of the parties to such documents, (iv) the authenticity of all documents submitted to us as originals, (v) the conformity to authentic original documents of all documents submitted to us as copies, (vi) that all information contained in all documents reviewed by us is true, correct and complete, and (vii) that the Shares will be issued in accordance with the terms of the Plan.

Based on the foregoing and subject to the limitations set forth herein, and having due regard for the legal considerations we deem relevant, we are of the opinion that the Common Units have been duly authorized and, when the Common Units are issued by the Partnership in accordance with the terms of the Plan, the Common Units will be validly issued, fully paid (to the extent required by the Partnership's partnership agreement) and non-assessable, except as such nonassessability may be limited by Sections 17-303, 17-607 and 17-804 of the Delaware Revised Uniform Limited Partnership Act or within
