In connection with the consummation of the transactions contemplated by the Contribution Agreement (Closing), the Contribution Agreement provides that the Issuer shall cause its board of directors (the Board) to consist of (i) the chief executive officer of the Issuer following Closing, (ii) three (3) directors designated by Blackstone Energy Partners II L.P., (iii) two (2) directors designated by ISQ Global Infrastructure Fund II L.P.

At Closing, the Contribution Agreement also provides that the Issuers existing registration rights agreement will be amended and restated to, among other things, add the Subject Shareholders following Closing as parties to such agreement and provide registration rights related to the Equity Consideration.

The Contribution Agreement provides that, following stockholder approval and in connection with Closing, the Issuer shall duly execute and submit the Third Amended and Restated Certificate of Incorporation as well as duly adopt the Amended and Restated Bylaws, in each case in a form attached to the Contribution Agreement, and which provide, among other things and subject to certain limitations and exceptions, (i) stockholders of the Issuer may act by written consent in lieu of holding a meeting of the stockholders, (ii) stockholders of the Issuer that own more than 10% of the outstanding shares of Common Stock may call a special meeting of the stockholders, (iii) directors on the Board may be removed with or without cause and (iv) revisions to the Corporate Opportunities article in the Issuers Second Amended and Restated Certificate of Incorporation.

Pursuant to the Voting Agreement, among other things, Apache Midstream agreed, among other things and subject to certain limitations and exceptions, to vote all shares of Common Stock constituting Covered Securities beneficially owned by Apache Midstream in favor of the adoption of the Contribution Agreement and any other matters necessary for consummation of the transactions contemplated thereby (the Transactions) in a manner to facilitate consummation of the Transactions contemplated by the Contribution Agreement (the Transaction Matters), and granted to Raptor an irrevocable proxy to vote such Covered Securities in accordance with the foregoing. One such exception is if the Board makes a Change in Company Recommendation (as defined in the Contribution Agreement), the number of shares of Common Stock constituting Covered Securities that are required to vote in favor of the Transaction Matters shall only represent (a) 35% of the total outstanding shares of Common Stock plus (b) a percentage of all shares of Common Stock beneficially owned by Apache Midstream not covered by clause (a) equal to the percentage of shares of Common Stock not beneficially owned by Apache Midstream (Non-Apache Shares) that vote in favor of Transaction Matters relative to the number of Non-Apache Shares that vote in favor of or against the Transaction Matters.

In addition, pursuant to the Voting Agreement, Apache Midstream has agreed, subject to certain limitations and exceptions, not to Transfer (as defined in the Voting Agreement) any or all of the Covered Securities beneficially owned by Apache Midstream or deposit any such Covered Securities into a voting trust or enter into a voting agreement or arrangement with respect to such Covered Securities or grant any proxy (except as provided in the Voting Agreement) or power of attorney with respect thereto.

The Voting Agreement shall terminate upon the earliest to occur of: (a) the Closing Date (as therein defined); and (b) the termination of the Contribution Agreement pursuant to and in compliance with the terms thereof.

The foregoing summary of the Voting Agreement does not purport to be complete and is subject to, and is qualified in its entirety by, the full text of the Voting Agreement, which is filed as Exhibit C to this Schedule 13D and is also incorporated herein by reference.

A&R Stockholders Agreement

On October 21, 2021, the Issuer entered into an amended and restated stockholders agreement (A&R SHA) with APA, Apache Midstream, New Raptor, certain other affiliates of the Reporting Persons who will own the Equity Consideration immediately following Closing (Subject Shareholders) and, solely for purposes of Sections 2(a)(iv) and 2(a)(v), Raptor.

The A&R SHA becomes effective immediately prior to, and conditioned upon, the Closing; provided that effective as of October 21, 2021 the parties to the A&R SHA agreed to negotiate and enter into a dividend reinvestment plan that shall be implemented shortly following Closing, be open to all holders of Common Stock, and require the Subject Shareholders and Apache Midstream to reinvest in such plan through 2023 at least 20% and up to 100% (as determined by the audit committee of the Board) of their respective quarterly dividends from Common Units and shares of Class A Common Stock held by such persons immediately following Closing.

Pursuant to the A&R SHA, the Subject Shareholders and Apache Midstream agreed, subject to certain limitations and exceptions, not to Transfer (as defined in the A&R SHA) Subject Securities (as defined in the A&R SHA) for 12 months following the Closing. The A&R SHA also provides that, subject to applicable law and other limitations, following Closing the Issuer shall not reduce its dividends on shares of Class A Common Stock below $1.50 a quarter through December 31, 2023 without the prior written consent of Apache Midstream and certain affiliates of Blackstone and ISQ for so long as such persons are entitled to nominate a director pursuant to the A&R SHA. Pursuant to the A&R SHA, any Covered Related Party Transaction (as defined in the A&R SHA) following Closing requires the prior approval of 66% or more of the disinterested directors on the Board, as determined by the Board.

Following Closing, the A&R SHA provides for continuing director nomination rights consistent with clauses (ii) (v) of the Contribution Agreement Board Composition and that an affiliate of Blackstone will have the right for a director it nominates to serve as the non-executive chairperson of the Board until December 31, 2024, subject in each case to certain limitations and reduced nomination rights depending on respective percentage ownership of the outstanding shares of Common Stock by such persons and their respective affiliates.

On October 21, 2021, and effective upon the Closing, the Issuer also entered into a voting agreement with certain affiliates of Blackstone (the Post-Closing Voting Agreement) pursuant to which such Blackstone affiliates agreed to vote all shares of Common Stock they beneficially own in favor of individuals designated to the Board pursuant to the A&R SHA. APA and Apache Midstream as well as an affiliate of ISQ also entered into separate similar voting agreements with the Issuer that shall be effective upon the Closing. The Reporting Persons expressly disclaim that they are a member of a group with any of such entities for the purposes of Section 13(d) of the Exchange Act or otherwise.

The foregoing description of the A&R SHA and the Post-Closing Voting Agreement do not purport to be complete and are subject to, and are qualified in their entirety by, the full text of the A&R SHA and the Post-Closing Voting Agreement, which are filed as Exhibits D and E, respectively, and are each also incorporated herein by reference.
