Exhibit 4.5

Restricted Unit Award Agreement

This Restricted Unit Award Agreement (this “Agreement”) is made and entered into as of the Date of Grant set forth in the Restricted Unit Award Grant Notice (“Notice of Grant”) by and between OMP GP LLC, a Delaware limited liability company (the “General Partner”), and [•] (“you” or “Service Provider”). Capitalized terms used but not specifically defined herein shall have the meanings specified in the Notice of Grant or the Oasis Midstream Partners LP 2017 Long Term Incentive Plan (the “Plan”), as applicable.

WHEREAS, the Oasis Midstream Partners LP, a Delaware limited partnership (the “Partnership”), acting through the Board of Directors of the General Partner (the “Board”), has adopted the Plan under which the General Partner is authorized to grant Restricted Units to certain Service Providers of the Partnership;

WHEREAS, the Partnership, in order to induce you to enter into and to continue to dedicate service to the Partnership and to materially contribute to the success of the Partnership, agrees to grant you the Restricted Unit Award;

WHEREAS, a copy of the Plan and the Notice of Grant have both been furnished to you and shall be deemed a part of this Agreement as if fully set forth herein; and

WHEREAS, you desire to accept the Restricted Unit Award made pursuant to this Agreement.

NOW, THEREFORE, in consideration of and mutual covenants set forth herein and for other valuable consideration hereinafter set forth, the parties agree as follows:

1. The Grant. Subject to the conditions set forth below, the Partnership hereby grants you effective as of the Date of Grant set forth in the Notice of Grant, as a matter of separate inducement but not in lieu of any salary or other compensation for your services to the Partnership, an Award consisting of the aggregate number of Restricted Units set forth in the Notice of Grant in accordance with the terms and conditions set forth in this Agreement, the Notice of Grant, and the Plan.

2. Rights of Service Provider. The Partnership shall evidence the Restricted Unit Award in the manner that it deems appropriate. The Partnership may issue in your name a certificate or certificates representing the Restricted Units granted pursuant to this Agreement and retain that certificate or those certificates until the restrictions on such Restricted Units granted pursuant to this Agreement expire as contemplated in Section 4 of this Agreement or are forfeited as contemplated in Sections 3 and 5. If the Partnership certificates the Restricted Units granted pursuant to this Agreement, you shall execute one or more unit powers in blank for those certificates and deliver those unit powers to the Partnership. The Partnership shall hold the Restricted Units granted pursuant to this Agreement and the related unit powers pursuant to the terms of this Agreement, if applicable, until such time as (a) a certificate or certificates for such Restricted Units are delivered to you, (b) such Restricted Units are otherwise transferred to you free of restrictions, or (c) such Restricted Units are canceled and forfeited pursuant to this Agreement. Notwithstanding the foregoing, the Service Provider shall have all the voting rights, if any, with respect to the Restricted Units granted pursuant to this Agreement and the right to

receive any distributions made by the Partnership with regard to a Restricted Unit granted pursuant to this Agreement (a “Unit Distribution Right” or “UDR”). Any Unit Distribution Rights payments will be made to the Service Provider in the same form as paid to unitholders on or promptly following the date that the Partnership pays such distribution to unitholders (however, in no event shall the payment be made later than 30 days following the date on which the Partnership pays such distribution to unitholders generally). Notwithstanding the date of payment, the Service Provider will vest in such Unit Distribution Right as of the record date for such distribution. No interest will accrue on any such right between the issuance of the distribution to unitholders generally and the settlement of the Unit Distribution Right.

3. Restrictions; Forfeiture. Except as provided in the Plan, the Restricted Unit award is restricted in that it may not be sold, transferred or otherwise alienated or hypothecated until these restrictions are removed or expire as contemplated in Section 4 of this Agreement and as described in the Notice of Grant. The Restricted Unit Award is also restricted in the sense that it may be forfeited to the Partnership (the “Forfeiture Restrictions”) as described in Section 5 of this Agreement. You hereby agree that if all or a portion of the Restricted Unit Award is forfeited as provided in Section 5, the Partnership shall have the right to deliver the forfeited Restricted Units to the Partnership’s transfer agent for cancellation.

4. Expiration of Restrictions and Risk of Forfeiture. The Forfeiture Restrictions will expire and the Restricted Unit Award will become transferable, except to the extent provided in Section 10 of this Agreement, and nonforfeitable as set forth in the Notice of Grant, provided that you remain a Service Provider to the Partnership or its Affiliates continuously from the Date of Grant until the applicable dates set forth therein.

5. Terminations of Services.

a. Termination Generally. Except as otherwise provided in the Notice of Grant and subject to Section 5(b) below, if your service relationship with the Partnership or any of its Affiliates is terminated for any reason, then the portion of the Restricted Unit Award for which the Forfeiture Restrictions has not lapsed as of the date of termination shall become null and void and such Restricted Units shall be cancelled. The portion of the Restricted Unit Award for which the Forfeiture Restrictions has lapsed as of the date of such termination shall not be cancelled.

b. Effect of Employment Agreement or Plan. Notwithstanding any provision herein to the contrary, in the event of any inconsistency between Section 5(a) and the terms of (i) any employment agreement entered into by and between you and the Partnership or its Affiliates (including Oasis Petroleum Inc.), (ii) the Oasis Petroleum Inc. Executive Change in Control and Severance Benefit Plan, to the extent you are a participant, or (iii) any similar or successor plan, to the extent you are a participant, the terms of such applicable agreement or plan shall control to the extent such agreement or plan addresses the Restricted Unit Award.

6. Leave of Absence. With respect to the Restricted Unit Award, the Partnership may, in its sole discretion, determine that if you are on a leave of absence for any reason, you will be considered to still be a Service Provider to the Partnership or its Affiliates; provided, that rights to the Restricted Unit Award during a leave of absence will be limited to the extent to which those rights were earned or vested when the leave of absence began.

7. Delivery of Units. Promptly following the expiration of the Forfeiture Restrictions, the Partnership shall cause to be issued and delivered to you or your designee a certificate or other evidence of the number of Units as to which the Forfeiture Restrictions have lapsed, free of any restricted legend relating to the lapsed restrictions, upon receipt by the Partnership of any tax withholding as may be required pursuant to Section 8. The value of such Units shall not bear any interest owing to the passage of time.

8. Payment of Taxes. The Partnership may require you to pay to the Partnership (or a Partnership Affiliate if you are a Service Provider to a Partnership Affiliate) an amount the Partnership deems necessary to satisfy its (or its Affiliates’) current or future obligation to withhold federal, state or local income or other taxes that you incur as a result of the Restricted Unit Award. With respect to any required tax withholding, you may (a) direct the Partnership to withhold from the Restricted Units to be issued to you under this Agreement the number of Units necessary to satisfy the Partnership’s obligation to withhold taxes, the determination of which will be based on the Units’ Fair Market Value at the time such determination is made; (b) deliver to the Partnership Units sufficient to satisfy the Partnership’s tax withholding obligations, based on the Units’ Fair Market Value at the time such determination is made; (c) deliver cash to the Partnership sufficient to satisfy its tax withholding obligations; or (d) satisfy such tax withholding through any combination of (a), (b) and (c). If you desire to elect to use the Unit withholding option described in subparagraph (a) or (b), you must make the election at the time and in the manner the Partnership prescribes. The Partnership, in its discretion, may deny your request to satisfy its tax withholding obligations using a method described under subparagraph (a) or (b). In the event the Partnership determines that the aggregate Fair Market Value of the Restricted Units withheld as payment of any tax withholding obligation is insufficient to discharge that tax withholding obligation, then you must pay to the Partnership, in cash, the amount of that deficiency immediately upon the Partnership’s request.

9. Compliance with Securities Laws; Partnership Policies. Notwithstanding any provision of this Agreement to the contrary, the issuance of Units will be subject to compliance with all applicable requirements of federal, state, or foreign law with respect to such securities and with the requirements of any securities exchange or market system upon which the Restricted Units may then be listed. No Units will be issued hereunder if such issuance would constitute a violation of any applicable federal, state, or foreign securities laws or other law or regulations or the requirements of any securities exchange or market system upon which the Units may then be listed. In addition, Units will not be issued hereunder unless (a) a registration statement under the Securities Act of 1933, as amended (the “Act”), is at the time of issuance in effect with respect to the Units issued or (b) in the opinion of legal counsel to the Partnership, the Units issued may be issued in accordance with the terms of an applicable exemption from the registration requirements of the Act. The inability of the Partnership to obtain from the applicable securities exchange or any regulatory body having jurisdiction the authority, if any, deemed by the Partnership’s legal counsel to be necessary for the issuance and sale of any Units subject to the Restricted Unit Award to be in compliance with securities exchange requirements and applicable law will relieve the Partnership of any liability in respect of the failure to issue such Units as to which such requisite authority has not been obtained. As a condition to any

issuance hereunder, the Partnership may require you to satisfy any qualifications that may be necessary or appropriate to evidence compliance with any applicable law or regulation and to make any representation or warranty with respect to such compliance as may be requested by the Partnership. From time to time, the Board and appropriate officers of the General Partner are authorized to take the actions necessary and appropriate to file required documents with governmental authorities, securities exchanges, and other appropriate Persons to make Units available for issuance. You hereby agree not to sell any Units acquired pursuant to this Restricted Unit Award in violation of the Partnership’s securities trading policy or in violation of any federal, state, or foreign law.

10. Lock-Up Period. You hereby agree that, if so requested by the Partnership or any representative of the underwriters (the “Managing Underwriter”) in connection with any registration of the offering of any securities of the Partnership under the Act, you will not sell or otherwise transfer any Units acquired hereunder or other securities of the Partnership during the 180-day period (or such other period as may be requested in writing by the Managing Underwriter and agreed to in writing by the Partnership) (the “Market Standoff Period”) following the effective date of a registration statement of the Partnership filed under the Act. Such restriction will apply only to the first registration statement of the Partnership to become effective under the Act that includes securities to be sold on behalf of the Partnership to the public in an underwritten public offering under the Act. The Partnership may impose stop-transfer instructions with respect to securities subject to the foregoing restrictions until the end of such Market Standoff Period.

11. Legends. The Partnership may at any time place legends referencing any restrictions imposed on the Units pursuant to Sections 3, 9 and 10 of this Agreement on all certificates representing Units issued with respect to this Restricted Unit Award.

12. Clawback. Notwithstanding any provisions in the Plan or this Agreement to the contrary, any portion of the payments and benefits provided under this Agreement or the sale of the Units granted hereunder shall be subject to any clawback policy adopted by the General Partner, including any such policy adopted to conform to the Xxxx-Xxxxx Xxxx Street Reform and Consumer Protection Act of 2010 and rules promulgated thereunder by the Securities and Exchange Commission, and including any such clawback policies adopted with retroactive effect.

13. Right of the Partnership and its Affiliates to Terminate Services. Nothing in this Agreement confers upon you the right to continue as a Service Provider for the Partnership or its Affiliates, or interfere in any way with the rights of the Partnership or its Affiliates to terminate your service relationship at any time.

14. Furnish Information. You agree to furnish to the Partnership all information requested by the Partnership to enable it to comply with any reporting or other requirements imposed upon the Partnership by or under any applicable statute or regulation.

Any payment of cash or any issuance or transfer of Restricted Units or other property to you, or to your legal representative, heir, legatee or distributee in accordance with the provisions hereof, shall, to the extent thereof, be in full satisfaction of all claims of such Persons hereunder. The Partnership may require you or your legal representative, heir, legatee or distributee, as a condition precedent to such payment or issuance, to execute a release and receipt therefor in such form as it shall determine.

17. No Guarantee of Interests. The Board and the Partnership do not guarantee the Restricted Units from loss or depreciation.

18. Partnership Records. Records of the Partnership or its Affiliates regarding your period of service, termination of service and the reason(s) therefor, leaves of absence, re-employment, and other matters shall be conclusive for all purposes hereunder, unless determined by the Partnership to be incorrect.

22. Severability. If any provision of this Agreement is held to be illegal or invalid for any reason, the illegality or invalidity shall not affect the remaining provisions hereof, but such provision shall be fully severable and this Agreement shall be construed and enforced as if the illegal or invalid provision had never been included herein.

23. Partnership or Committee Action. Any action required of the Partnership or the General Partner shall be by resolution of the Board or Committee or by a Person or entity authorized to act by resolution of the Board or Committee.
