Item 1.01 Entry into a Material Definitive Agreement.

Merger Agreement

On October 25, 2021, Oasis Petroleum Inc. (the “Company”) Oasis Midstream Partners LP, a Delaware limited partnership (“OMP”) and OMP GP LLC, a Delaware limited liability company and the general partner of OMP (the “General Partner”), entered into an Agreement and Plan of Merger (the “Merger Agreement”), with Crestwood Equity Partners LP, a Delaware limited partnership (“Crestwood”), Project Falcon Merger Sub LLC, a Delaware limited liability company and direct wholly owned subsidiary of Crestwood (“Merger Sub”), Project Phantom Merger Sub LLC, a Delaware limited liability company and direct wholly owned subsidiary of Crestwood (“GP Merger Sub”), and, solely for the purposes of Section 2.1(a)(i) of the Merger Agreement, Crestwood Equity GP LLC, a Delaware limited liability company and the general partner of Crestwood (“Crestwood GP”). Upon the terms and subject to the conditions set forth in the Merger Agreement, Merger Sub will merge with and into OMP (the “LP Merger”), with OMP surviving the LP Merger as a subsidiary of Crestwood, and GP Merger Sub will merge with and into the General Partner (the “GP Merger” and, together with the LP Merger, the “Mergers”), with the General Partner surviving the GP Merger as a wholly owned subsidiary of Crestwood.

At the effective time of the Mergers (the “Effective Time”): (i) 6,520,944 common units representing limited partner interests in OMP (the “OMP Common Units”) issued and outstanding immediately prior to the Effective Time and owned by OMS Holdings LLC, a Delaware limited liability company (“OMS Holdings”) and subsidiary of the Company (such OMP Common Units, the “Sponsor Cash Units”), will be converted into and will thereafter represent the right to receive $150,000,000 in cash in the aggregate and each other OMP Common Unit issued and outstanding immediately prior to the Effective Time owned by the Company or its subsidiaries (other than OMP) (together with the Sponsor Cash Units, the “Sponsor Units”) will be converted into and will thereafter represent the right to receive 0.7680 common units representing limited partner interests in Crestwood (“Crestwood Common Units”); (ii) each OMP Common Unit issued and outstanding immediately prior to the Effective Time (other than the Sponsor Units) will be converted into and will thereafter represent the right to receive 0.8700 (the “Public Holder Exchange Ratio”) Crestwood Common Units and (iii) all of the limited liability company interests of the General Partner issued and outstanding as of immediately prior to the Effective Time will be converted into and will thereafter represent the right to receive $10,000,000 in cash. Upon completion of the Mergers, the Company is expected to own approximately 21.7% of the Crestwood common units.

Each award of restricted units that corresponds to OMP Common Units, vested or unvested (each, an “OMP Restricted Unit Award”), that is outstanding immediately prior to the Effective Time, will, immediately prior to the Effective Time, automatically become fully vested to the extent unvested and will, without any action on the part of OMP, Crestwood or the holder thereof and subject to satisfaction of all applicable tax withholding obligations, be cancelled and converted into a right to receive a number of unrestricted Crestwood Common Units equal to the product obtained by multiplying the number of OMP Common Units subject to such OMP Restricted Unit Award immediately prior to the Effective Time by the Public Holder Exchange Ratio.

The completion of the Mergers is subject to the satisfaction or waiver of customary closing conditions, including, among others: (i) adoption of the Merger Agreement by holders of a majority of the outstanding OMP Common Units entitled to vote thereon, (ii) absence of any court order or regulatory injunction prohibiting completion of the Mergers, (iii) expiration or termination of review under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), (iv) effectiveness of a registration statement of Crestwood on Form S-4 (the “Form S-4”) in connection with the issuance of Crestwood Common Units in the LP Merger, (v) the mailing of the combined consent statement/prospectus to all holders of OMP Common Units following effectiveness of the Form S-4 and at least 20 days prior to the closing date, (vi) the authorization for listing of Crestwood Common Units to be issued in the LP Merger on the NYSE and (vii) the consummation of the Pre-Closing Transactions (as defined in the Merger Agreement). The obligation of each of OMP and Crestwood to consummate the Mergers is also conditioned upon compliance by the other party in all material respects with its covenants and, subject to materiality standards specified in the Merger Agreement, the accuracy of the representations and warranties of the other party.

Crestwood and OMP have made customary representations and warranties in the Merger Agreement. The Merger Agreement also contains customary covenants and agreements, including covenants and agreements relating to (i) the conduct of each of OMP’s and Crestwood’s respective businesses between the date of the signing of the Merger Agreement and the Effective Time and (ii) the efforts of the parties to cause the Mergers to be completed, including actions which may be necessary to cause the expiration or termination of the waiting period under the HSR Act. Pursuant to the terms of the Merger Agreement, each of Crestwood and OMP shall use its reasonable best efforts to take any and all steps necessary, subject to certain limitations, to obtain antitrust clearance in order to facilitate closing of the Mergers.

2

The Merger Agreement contains certain termination rights for OMP and Crestwood as more particularly set forth in the Merger Agreement. The Merger Agreement further provides that, upon termination of the Merger Agreement under certain circumstances, OMP may be required to pay Crestwood a termination fee of $40,000,000.

At the closing of the transactions contemplated by the Merger Agreement, the Company will enter into a Registration Rights Agreement, a Director Nomination Agreement, Master Amendment to Commercial Agreements and the Transition Services Agreement, forms of which are attached as exhibits to the Merger Agreement.

The Registration Rights Agreement will grant the Company and certain of its affiliates (the “Unitholders”) certain rights to require Crestwood to file and maintain the effectiveness of a registration statement with respect to the resale of the Crestwood Common Units owned by the Unitholder (including by having their Crestwood Common Units registered for resale in certain other registration statements filed by Crestwood or in certain underwritten offerings proposed by Crestwood) and, under certain circumstances, to require Crestwood to initiate three underwritten offerings for such Crestwood Common Units, subject to a minimum threshold.

Also pursuant to the Registration Rights Agreement, the Unitholders will agree not to directly or indirectly sell or otherwise dispose of its Crestwood Common Units for a period ending 90 days following the closing date. Additionally, for a period of two years following the closing date, Crestwood will have a right of first offer in connection with certain sales by the Unitholders of Crestwood Common Units.

The Director Nomination Agreement will grant the Company certain designation rights pursuant to which the Company may cause the board of directors of the Crestwood GP to elect the designees selected by the Company. At the closing, the Company may designate two directors to the board of directors of Crestwood GP and for so long as it and its affiliates own 15% of the issued and outstanding Crestwood Common Units. The Company may designate one director if the Company and its affiliates hold at least 10% (but less than 15%) of the issued and outstanding Crestwood Common Units.

The Master Amendment to Commercial Agreements will amend certain commercial agreements between the Company and OMP at closing, as more particularly set forth in the Master Amendment to Commercial Agreements.

Under the Transition Services Agreement, a subsidiary of the Company will provide customary transition services to Crestwood for a limited duration.

The transaction has been unanimously approved by the board of directors of the Company and both general partners of Crestwood and OMP. The transaction terms were reviewed, negotiated and approved by the conflicts committee of the board of directors of the general partner of OMP. In making its determination to approve the transaction, the board of directors consulted with its management and financial and legal advisors and considered a number of factors including, among other things, strategic alternatives for its midstream business, precedent midstream transactions and, among other things, an opinion received from Morgan Stanley & Co. LLC to the effect that, as of the date of such opinion and based upon and subject to the assumptions, limitations, qualifications and other matters set forth therein, the consideration to be received by the Company and its subsidiaries (other than OMP), in the Mergers, was fair from a financial point of view to the Company. Morgan Stanley’s opinion was solely for the information of the board of directors of the Company in connection with its consideration of the Mergers and does not address the consideration to be received by any other person in connection with the Mergers or the relative fairness of the consideration to be received by the Company and its subsidiaries (or any component thereof) as compared with the Public Holder Exchange Ratio.

Support Agreement

Contemporaneously with the execution of the Merger Agreement, the Company, OMP, Crestwood, the General Partner and OMS Holdings entered into a support agreement (the “Support Agreement”) regarding the OMP Common Units owned by the Company and OMS Holdings (or their affiliates). Pursuant to the Support Agreement, the Company and OMS Holdings have agreed to, among other things (and as applicable), following effectiveness of the Form S-4, execute and deliver, or cause an affiliate to execute and deliver, a written consent (the “Written Consent”) covering all of their OMP Units, approving the Merger Agreement and the transactions contemplated thereby. The Support Agreement and the Merger Agreement may be terminated in the event the Written Consent is not delivered.

In addition, the Support Agreement includes certain affirmative and restrictive covenants of the parties, including, among others, the Company’s waiver of certain consent, notice, approval and re-negotiation rights under certain Commercial Agreements (as defined in the Support Agreement) that would be triggered by the transactions contemplated by the Merger Agreement.

The Support Agreement is attached hereto as Exhibit 10.1 and is incorporated into this Item 1.01 by reference. The foregoing summary has been included to provide investors and security holders with information regarding the terms of the Support Agreement and is qualified in its entirety by the terms and conditions of the Support Agreement.

Moreover, information concerning the subject matter of the representations, warranties and covenants may change after the date of the Support Agreement, which subsequent information may or may not be fully reflected in the Company’s, OMP’s or Crestwood’s public disclosures.

Cautionary Statement Regarding Forward-Looking Statements

This Current Report on Form 8-K contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. All statements, other than statements of historical facts, included in this Current Report on Form 8-K that address activities, events or developments that the Company expects, believes or anticipates will or may occur in the future are forward-looking statements. Without limiting the generality of the foregoing, forward-looking statements contained in this Current Report on Form 8-K specifically include the expectations of plans, strategies, objectives and anticipated financial and operating results of the Company, including the Company’s drilling program, production, derivative instruments, capital expenditure levels and other guidance included in this Current Report on Form 8-K, as well as the impact of the novel coronavirus 2019 (“COVID-19”) pandemic on the Company’s operations. These statements are based on certain assumptions made by the Company based on management’s experience and perception of historical trends, current conditions, anticipated future developments and other factors believed to be appropriate. Such statements are subject to a number of assumptions, risks and uncertainties, many of which are beyond the control of the Company, which may cause actual results to differ materially from those implied or expressed by the forward-

4

looking statements. These include, but are not limited to, risks that the proposed transaction may not be consummated or the benefits contemplated therefrom may not be realized, the ability to obtain requisite regulatory and unitholder approval and the satisfaction of the other conditions to the consummation of the proposed transaction, the ability of Crestwood to successfully integrate OMP’s operations and employees and realize anticipated synergies and cost savings, the potential impact of the announcement or consummation of the proposed transaction on relationships, including with employees, suppliers, customers, competitors and credit rating agencies, changes in crude oil and natural gas prices, developments in the global economy, particularly the public health crisis related to the COVID-19 pandemic and the adverse impact thereof on demand for crude oil and natural gas, the outcome of government policies and actions, including actions taken to address the COVID-19 pandemic and to maintain the functioning of national and global economies and markets, the impact of Company actions to protect the health and safety of employees, vendors, customers, and communities, weather and environmental conditions, the timing of planned capital expenditures, availability of acquisitions, the ability to realize the anticipated benefits from the Williston Basin acquisition and Permian Basin divestitures, uncertainties in estimating proved reserves and forecasting production results, operational factors affecting the commencement or maintenance of producing wells, the condition of the capital markets generally, as well as the Company’s ability to access them, the proximity to and capacity of transportation facilities, and uncertainties regarding environmental regulations or litigation and other legal or regulatory developments affecting the Company’s business and other important factors that could cause actual results to differ materially from those projected as described in the Company’s reports filed with the U.S. Securities and Exchange Commission (the “SEC”). Additionally, the unprecedented nature of the COVID-19 pandemic and the related decline of the oil and gas exploration and production industry may make it particularly difficult to identify risks or predict the degree to which identified risks will impact the Company’s business and financial condition. Because considerable uncertainty exists with respect to the future pace and extent of a global economic recovery from the effects of the COVID-19 pandemic, the Company cannot predict whether or when crude oil production and economic activities will return to normalized levels. Any forward-looking statement speaks only as of the date on which such statement is made and the Company undertakes no obligation to correct or update any forward-looking statement, whether as a result of new information, future events or otherwise, except as required by applicable law.
