Contribution Agreement and Closing Transactions

On February 22, 2022, the Issuer completed the transactions contemplated by that certain Contribution Agreement, dated October 21, 2021, (the Contribution Agreement and the completion of such transactions, the Closing) by and among the Issuer, the Partnership, New BCP Raptor Holdco, LLC, a Delaware limited liability company (New Raptor), and, solely for the purposes set forth therein, BCP Raptor Holdco, LP, a Delaware limited partnership (Raptor). Pursuant to the Contribution Agreement, New Raptor contributed all of the equity interests of Raptor and BCP Raptor Holdco GP, LLC, a Delaware limited liability company, to the Partnership in exchange for 50,000,000 Common Units and 50,000,000 shares of Class C Common Stock.

In connection with the receipt of such Common Units and shares of Class C Common Stock, 2,650,000 Common Units were redeemed on a one-for-one basis for shares of Class A Common Stock (the Conversion), with 2,599,801 of those shares being subject to forfeiture back to the Company in certain circumstances (the Restricted Shares), and a corresponding number of shares of Class C Common Stock were cancelled. Following the Conversion, New Raptor distributed the Equity Consideration (as defined below) on a pro rata basis, subject to certain transfer restrictions and, in the case of the Restricted Shares, forfeiture provisions set forth on the legends thereto (the Distribution). The transactions contemplated by the Contribution Agreement, the Conversion and the Distribution are collectively referred to herein as the Transactions.

In connection with Distribution, the Issuer entered into that certain Consideration Allocation Rights Agreement, dated as of February 22, 2022, with BCP Aggregator, BX Permian, Buzzard Midstream LLC, a Delaware limited liability company and controlled affiliate of ISQ Global Infrastructure Fund II L.P. (Buzzard), and certain other parties listed on the signature pages thereto (the Consideration Allocation Agreement), pursuant to which the Issuer agreed that it would re-issue, on a one-for-one basis, shares of Class A Common Stock to the extent Restricted Shares are forfeited by the original holders thereof on February 25, 2025 and February 26, 2026, or an

earlier settlement date as described in the certain restricted stock agreements (such rights to receive re-issued shares, Consideration Allocation Rights, and together with Common Units and Class C Common Stock received at Closing, the Equity Consideration). Shares of Class A Common Stock will be issued pursuant to Consideration Allocation Rights solely to the extent a corresponding forfeiture of Restricted Shares has occurred.

The descriptions of the Contribution Agreement and Consideration Allocation Rights contained in this Item 6 do not purport to be complete and are subject to, and are qualified in their entirety by, the full text of the Contribution Agreement, the Consideration Allocation Agreement and the form of restricted stock agreement, which are filed as Exhibits B, C and D, respectively, and are also incorporated herein by reference.

Pursuant to the A&R SHA, the Subject Shareholders and Apache Midstream each agreed with the Issuer, 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 Buzzard 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.

The A&R SHA provides for continuing director nomination rights for each of Apache, Blackstone and Buzzard. BCP Aggregator and BX Permian will collectively have the right to designate three directors for so long as BCP Aggregator, BX Permian and their affiliates beneficially own 30% or more of the outstanding Common Stock, two directors for so long as BCP Aggregator, BX Permian and their affiliates beneficially own 20% or more but less than 30% of the outstanding Common Stock and one director for so long as BCP Aggregator, BX Permian and their affiliates beneficially own 10% or more but less than 20% of the outstanding Common Stock.

The Registration Rights Agreement will require the Issuer to file, within 90 days of the Closing Date, a registration statement on Form S-3 (or, if Form S-3 is not then available, on Form S-1) to permit the public resale of all Registrable Securities held by the Principal Holders, other than any Registrable Securities that are registered for sale on a registration statement filed prior to the execution of the Registration Rights Agreement and effective as of the Closing Date. Holders will also be entitled to certain demand rights, pursuant to which Holders will also be entitled to require the Issuer to effectuate a distribution of any or all of its Registrable Securities by means of an underwritten offering, provided that the Issuer will not be obligated to effect an underwritten offering unless the dollar amount of the Registrable Securities of the demanding Holders and their respective affiliates to be included therein is reasonably likely to result in gross sale proceeds that exceed the minimum amount.

Except for a Permitted Apache Offering (as defined in the Registration Rights Agreement) or as required in connection with the initial registration of Registrable Securities on Form S-3 (or Form S-1 if Form S-3 is not then available) pursuant to the Registration Rights Agreement, no registration shall be effected or permitted with respect to any Registrable Securities held by any holder until after the expiration of the lock-up period, which occurs, with respect to the Principal Holders, 12 months after the Closing of the transaction.

The audit committee of the Board shall have the authority to increase the percentage of the mandatory dividend reinvestment to up to 100%. All shares of Class A Common Stock issued in connection with the Mandatory DRIP will be valued at a 3% discount to the volume weighted average price for the five trading days immediately preceding, but excluding, the applicable dividend or distribution date.

The foregoing description of the DRIP Agreement does not purport to be complete and is subject to, and is qualified in its entirety by, the full text of the DRIP Agreement, which is filed as Exhibit H and is also incorporated herein by reference.

Partnership Agreement

Concurrently with the execution of the contribution agreement, on October 21, 2021, a Third Amended and Restated Agreement of Limited Partnership of the Partnership (the Third A&R LPA) was adopted by the general partner and limited partners holding more than 67% of the outstanding Series A Preferred Units and 100% of the outstanding Common Units of the Partnership. The Third A&R LPA became effective concurrently with the effective time of the Transactions and provides for, among other things, admission of New Raptor, the BX Holders and Buzzard as limited partners thereunder, updates to certain tax-related provisions, and amendment of certain provisions relating to the Series A Preferred Units.

Pursuant to the Third A&R LPA, each holder of Common Units (other than the Issuer) generally has the right to cause the Partnership to redeem all or a portion of its Common Units in exchange for shares of Class A Common Stock or, at the Partnerships option, an equivalent amount of cash; provided that the Issuer may, at its option, effect a direct exchange of cash or Class A Common Stock for such Common Units in lieu of such a redemption by the Partnership.

The foregoing description of the Third A&R LPA does not purport to be complete and is subject to, and is qualified in its entirety by, the full text of the Third A&R LPA, which is filed as Exhibit I and is also incorporated herein by reference.

The foregoing description of the Letter Agreement does not purport to be complete and is subject to, and is qualified in its entirety by, the full text of the Letter Agreement, which is filed as Exhibit J and is also incorporated herein by reference.
