Pursuant to the DCP Merger Agreement (as defined below), the Merger Consideration (as defined below) described in Item 4 of this Amendment No. 13 (which Item 4 is incorporated herein by reference) will consist entirely of cash and is estimated to total approximately $3.8 billion in the aggregate. The Merger Consideration is expected to be funded from a combination of existing cash on hand and proceeds from newly issued debt securities or borrowings under existing credit facilities.

**Item 4. Purpose of Transaction.** 

The information previously provided in response to this Item 4 is hereby amended and supplemented by adding the following paragraphs:

*DCP Merger Agreement* 

On January 5, 2023, PSX, P66 Project Development, Dynamo Merger Sub LLC, a Delaware limited liability company and wholly owned subsidiary of P66 Project Development ("<u>Merger Sub</u>"), the Partnership, the General Partner and GP LLC entered into an Agreement and Plan of Merger (the "<u>DCP Merger Agreement</u>"), pursuant to which Merger Sub will merge with and into the Partnership, with the Partnership surviving as a Delaware limited partnership (the "<u>Merger</u>").

Under the terms of the DCP Merger Agreement, at the effective time of the Merger (the "<u>Effective Time</u>"), each Common Unit issued and outstanding as of immediately prior to the Effective Time (other than the Sponsor Owned Units, as defined below) (each, a "<u>Public Common Unit</u>") will be converted into the right to receive $41.75 per Public Common Unit in cash, without any interest thereon (the "<u>Merger Consideration</u>").

The General Partner of the Partnership has agreed to declare, and cause the Partnership to pay, a cash distribution in respect of the Common Units in an amount equal to $0.43 per Common Unit for each completed quarter ending on or after December 31, 2022 and prior to the Effective Time. If the record date for any such distribution has not occurred prior to the Effective Time, the Partnership will establish or reestablish the record date for such quarter as the day that includes the Effective Time.

Following the completion of the Merger, the Common Units will cease to be listed on the New York Stock Exchange, will be deregistered under the Exchange Act and will cease to be publicly traded.

The Partnership's preferred units will be unaffected by the Merger and will remain outstanding immediately following the Merger.

The Common Units directly owned by Midstream and the General Partner (collectively, the "<u>Sponsor Owned Units</u>") will be unaffected by the Merger and will remain outstanding immediately following the Merger. Under the terms of the DCP Merger Agreement, at the Effective Time, P66 Project Development's ownership interest in Merger Sub will be converted into a number of new Common Units equal to the number of Public Common Units (which, as of December 30, 2022, consisted of 90,634,032 Common Units). As a result of the Merger, PSX's economic interest in the Partnership will increase from 43.3% to approximately 86.8%. Enbridge Inc.'s economic interest in the Partnership will remain unchanged at approximately 13.2%.

The DCP Merger Agreement contains customary representations and warranties from the parties and each party has agreed to customary covenants. Completion of the Merger is subject to certain customary conditions, including, among others: (i) there being no law or injunction prohibiting consummation of the transactions contemplated under the DCP Merger Agreement; (ii) the mailing of an information statement on Schedule 14C at least 20 days prior to the closing of the Merger; (iii) subject to specified materiality standards, the accuracy of the representations and warranties of each party; and (iv) compliance by each party in all material respects with its respective covenants.

The DCP Merger Agreement provides for certain termination rights for both PSX and the Partnership, including in the event that (i) the parties agree by mutual written consent to terminate the DCP Merger Agreement; (ii) the closing of the Merger does not occur on or before October 5, 2023; (iii) a law or injunction prohibiting the consummation of the transactions contemplated by the DCP Merger Agreement is in effect and has become final and non-appealable; or (iv) the other party is in material breach of the DCP Merger Agreement.

The foregoing summary of the DCP Merger Agreement and the transactions contemplated thereby does not purport to be complete and is qualified in its entirety by reference to the full text of the DCP Merger Agreement, a copy of which is filed as Exhibit 10.10 to this Amendment No. 13 and incorporated herein by reference.

*Approval of DCP Merger Agreement by Written Consent* 

The board of directors of GP LLC, which is the general partner of the General Partner, authorized the holders of Common Units to act by written consent pursuant to the terms of the Fifth Amended and Restated Agreement of Limited Partnership of the Partnership in order to provide their approval of the DCP Merger Agreement and the transactions contemplated thereby, including the Merger. On January 5, 2023, concurrently with the execution and delivery of the DCP Merger Agreement, Midstream and the General Partner, which, together, own greater than a majority of the outstanding Common Units, delivered a written consent to the General Partner that was sufficient to approve the DCP Merger Agreement and the transactions contemplated thereby, including the Merger.
