Introductory Note

On October 19, 2018, Energy Transfer Equity, L.P., a Delaware limited partnership (“ETE”), changed its name to “Energy Transfer LP” and completed its acquisition of Energy Transfer Partners, L.P., a Delaware limited partnership (“ETP”). Further, since the date of the filing of Amendment No. 4 to the Schedule 13D by certain of the Reporting Persons, all of the Common Units directly held by the respective subsidiaries of ETE and ETP are now directly held by ET. As a result, all Common Units theretofore held by ETE and ETP and their respective subsidiaries are now directly held by ET.

The Merger

On January 22, 2024, the Issuer, Saturn Merger Sub, LLC, a Delaware limited liability company and a direct wholly owned subsidiary of the Issuer (“Merger Sub”), NuStar Energy L.P., a Delaware limited partnership (“NSE”), Riverwalk Logistics, L.P., a Delaware limited partnership (“NSE GP”) and sole general partner of NSE, NuStar GP, LLC, a Delaware limited liability company and the sole general partner of NSE GP, and SUN GP entered into an Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which Merger Sub will be merged with and into NSE (the “Merger”, and the effective time of the merger, the “Effective Time”), with NSE surviving the Merger as the surviving entity and a subsidiary of the Issuer. As a result of the Merger, each issued and outstanding common unit of NSE prior to the Effective Time will be converted into the right to receive .400 of a common unit representing limited partner interests in the Issuer.

A copy of the Merger Agreement was filed as Exhibit 2.1 to the Current Report on Form 8-K filed by the Issuer with the Securities and Exchange Commission (the “SEC”) on January 22, 2024 and is incorporated herein by reference.

The Support Agreement

Concurrently with the execution of the Merger Agreement, the Issuer, NSE and ET entered into a Support Agreement (the “Support Agreement”), pursuant to which ET, the general partner of SUN GP, agreed, among other things, and subject to certain exceptions, (i) to take all necessary actions to increase the board of directors of SUN GP by one member, and to appoint a new member, to be mutually agreed upon by the Issuer and NSE to fill such vacancy, prior to the Effective Time (such appointment, the “Director Appointment”); (ii) not to, nor would ET cause SUN GP to, directly or indirectly, transfer, pledge, sell or otherwise dispose of any interest in the SUN GP, any of the Issuer’s incentive distribution rights or any material portion of the Common Units beneficially owned by ET, from the entry into the Support Agreement until the earlier of the Effective Time and the termination date in accordance with the Merger Agreement (such restriction, the “Transfer Restriction”); and (iii) to be bound by the terms of the non-solicitation provisions in the Merger Agreement with respect to competing proposals for the Issuer and SUN GP and to abide by certain covenants with respect to regulatory approvals, SEC filings, confidentiality and litigation.

A copy of the Merger Agreement was filed as Exhibit 10.1 to the Current Report on Form 8-K filed by the Issuer with the SEC on January 22, 2024 and is incorporated herein by reference.

The Reporting Persons reserve the right to acquire additional securities of the Issuer in the open market, in privately negotiated transactions (which may be with the Issuer or with third parties) or otherwise, to dispose of all or a portion of their holdings of securities of the Issuer or to change their intention with respect to any or all of the matters referred to in this Item 4.
