Agreement and Plan of Merger

On November 24, 2024, EnLink Midstream, LLC, a Delaware limited liability company (the “Company”), EnLink Midstream Manager, LLC, a Delaware limited liability company and the managing member of the Company (the “Manager”), ONEOK, Inc., an Oklahoma corporation (“Parent”), Elk Merger Sub I, L.L.C., a Delaware limited liability company and a direct, wholly-owned subsidiary of Parent (“Merger Sub I”), and Elk Merger Sub II, L.L.C., a Delaware limited liability company and a direct, wholly-owned subsidiary of Parent (“Merger Sub II” and, together with Merger Sub I, the “Merger Subs”), entered into a definitive Agreement and Plan of Merger (the “Merger Agreement”). Upon the terms and subject to the conditions set forth in the Merger Agreement, Merger Sub I will merge with and into the Company (the “First Merger”), with the Company surviving and continuing to exist as a Delaware limited liability company and, promptly following the First Merger, the Company will merge with and into Merger Sub II (the “Second Merger” and, together with the First Merger, the “Mergers” and, together with the other transactions contemplated by the Merger Agreement, the “Transaction”), with Merger Sub II surviving and continuing to exist as a Delaware limited liability company.

At the effective time of the First Merger (the “First Merger Effective Time”), each common unit representing limited liability company interests in the Company (each, a “Common Unit”) issued and outstanding as of immediately prior to the First Merger Effective Time (except for any Common Units that are owned immediately prior to the First Merger Effective Time by the Company as treasury units, if any, or by the Manager, Parent or the Merger Subs) (the “Public Common Units”), will be converted into the right to receive 0.1412 shares (the “Exchange Ratio”) of common stock of Parent, par value $0.01 (a “Parent Share”). As of the effective time of the Mergers, the limited liability company interests in the Manager, and any Common Units that are owned immediately prior to the First Merger Effective Time by the Manager, Parent or the Merger Subs will remain unchanged and outstanding and the Manager will continue as the sole manager of the Company.

The Conflicts Committee (the “Manager Conflicts Committee”) of the Board of Directors of the Manager (the “Manager Board”) has (i) determined that the Transaction, on the terms and conditions set forth in the Merger Agreement and the Support Agreement, is in the best interests of the Company and the holders of the Public Common Units (the “Company Unaffiliated Unitholders”), (ii) approved the Merger Agreement and the Support Agreement and the transactions contemplated thereby, including the Mergers, with such approval constituting “Special Approval” for all purposes under the Second Amended and Restated Operating Agreement of the Company, dated as of January 25, 2019 (the “Company Operating Agreement”), including, but not limited to, Section 7.9(d) thereof, and the execution, delivery, and performance of the Merger Agreement and the Support Agreement and the transactions contemplated thereby, (iii) recommended that the Manager Board approve the Merger Agreement and the Support Agreement and the transactions contemplated thereby, including the Mergers, and the execution, delivery, and performance of the Merger Agreement and the Support Agreement and the transactions contemplated thereby, including the Mergers, and (iv) recommended (a) that the Manager Board resolve to direct that the Merger Agreement and the approval of the Mergers be submitted to a vote of the holders of the Common Units (the “Company Unitholders”) and (b) that the Company Unitholders approve the Merger Agreement and the Mergers.

The Manager Board (acting based upon the recommendation of the Manager Conflicts Committee) has (i) determined that the Mergers, on the terms and conditions set forth in the Merger Agreement and the Support Agreement, are in the best interests of the Company and the Company Unitholders, (ii) approved the Merger Agreement and the Support Agreement, the execution, delivery, and performance of the Merger Agreement and the Support Agreement and the transactions contemplated thereby, (iii) directed that the Merger Agreement and the Mergers be submitted to a vote of the Company Unitholders, and (iv) recommended approval of the Merger Agreement and the Mergers by the Company Unitholders.

Concurrently with the execution of the Merger Agreement, Parent entered into a support agreement with the Company (the “Support Agreement”), pursuant to which, among other things, Parent agreed to vote the 200,340,753 Common Units it holds of record in favor of the Merger Agreement, the Mergers, and the other transactions contemplated thereby on the terms and subject to the conditions provided for in the Support Agreement. The Support Agreement terminates upon the earliest to occur of (i) the First Merger Effective Time, (ii) the termination of the Merger Agreement in accordance with its terms, and (iii) the mutual written agreement of the parties.

The Merger Agreement provides that the Company will convene and hold a special meeting of the Company Unitholders (the “Company Unitholder Meeting”) for the purpose of obtaining the approval of the Merger Agreement and the Mergers at the Company Unitholder Meeting or any adjournment or postponement thereof by the vote of a Unit Majority (as defined in the Company Operating Agreement) (the “Company Unitholder Approval”). In certain circumstances, the Company and the Manager, acting through the Manager Board or the Manager Conflicts Committee, may withdraw, modify, or qualify, or propose publicly to withdraw, modify, or qualify, in a manner adverse to Parent, the Company Board Recommendation (as defined in the Merger Agreement) to the Company Unitholders to approve the Merger Agreement or (b) fail to include the Company Board Recommendation in the Proxy Statement (the taking of any such action in subclause (a) and (b) being referred to as a “Company Adverse Recommendation Change”), subject to certain rights of Parent. However, even if the Manager Conflicts Committee or the Manager Board effects a Company Adverse Recommendation Change, the Merger Agreement requires that the Company still submit the Merger Agreement for approval by the Company Unitholders at the Company Unitholder Meeting unless the Merger Agreement has been validly terminated in accordance with the terms of the Merger Agreement.

The Merger Agreement contains customary representations and warranties from the parties, and each party has agreed to customary covenants, including, among others, covenants relating to (i) the conduct of business during the interim period between the execution of the Merger Agreement and the First Merger Effective Time and (ii) the obligation to use reasonable best efforts to cause the Mergers to be consummated.

The Merger Agreement also contains customary closing conditions, including, among others: (i) obtaining Company Unitholder Approval; (ii) there being no law, injunction, judgment, or ruling prohibiting or making illegal the consummation of the transactions contemplated by the Merger Agreement; (iii) the effectiveness of Parent’s registration statement on Form S-4 (the “Registration Statement”) to register the Parent Shares to be issued as consideration in the Mergers; (iv) the approval for the listing of the Parent Shares to be issued as consideration in the Mergers on the New York Stock Exchange, subject to official notice of issuance; (v) the receipt by the Company of an opinion of tax counsel that, for U.S. federal income tax purposes, the Mergers should qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended; (vi) subject to specified materiality standards, the accuracy of certain representations and warranties of each party; and (vii) compliance by each party in all material respects with all obligations required to be performed under the Merger Agreement at or prior to the closing date.

The Merger Agreement contains certain termination rights for both Parent and the Company, including, among others, in the event that (i) the parties agree by mutual written consent to terminate the Merger Agreement; (ii) the Mergers have not been consummated on or before May 23, 2025; (iii) a law, injunction, judgment, or ruling prohibiting or making illegal the consummation of the transactions contemplated by the Merger Agreement is in effect and has become final and non-appealable; (iv) the Company Unitholder Meeting and any postponements or adjournments thereof have concluded and the Company Unitholder Approval has not been obtained; or (v) a party has breached or failed to perform any of its representations, warranties, covenants, or agreements set forth in the Merger Agreement that would give rise to the failure of certain closing conditions to occur and such breach or failure is incapable of being cured, or is not cured, by such party within 30 days following receipt of written notice from the other party of such breach. The Merger Agreement also provides for a termination right for Parent if a Company Adverse Recommendation Change has occurred prior to the Company Unitholder Meeting. The Merger Agreement provides that upon termination of the Merger Agreement under certain circumstances, (a) the Company will be obligated to reimburse Parent for its expenses up to a maximum amount of $10,000,000; (b) Parent will be obligated to reimburse the Company for its expenses up to a maximum amount of $10,000,000; or (c) the Company will be obligated to pay to Parent a termination fee equal to $143,978,000.

They are not intended to provide any other factual information about Parent, the Manager, the Merger Subs, or the Company, or their respective subsidiaries or affiliates.
