No changes to this item.

Item 2.

Identity and Background

No changes to this item.

Item 3.

Source and Amount of Funds or Other Consideration

Item 3 is hereby amended and supplemented by adding the following paragraph:

Pursuant to the Merger Agreement described in Item 4 of this Amendment No.6 (which Item 4 is incorporated herein by reference), the funding for the Merger will consist entirely of cash funded from a combination of existing cash on hand and/or borrowings under existing credit facilities. The Merger will not be subject to any financing condition.

Item 4.

Purpose of Transaction

Item 4 is hereby amended to add the following paragraphs:

On July 25, 2022, Shell USA, Inc., a Delaware corporation (“Parent”), LP Holdco, Semisonic Enterprises LLC, a Delaware limited liability company and indirect wholly owned subsidiary of Parent (“Merger Sub”), the Partnership, and the General Partner entered into an Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which Merger Sub will be merged with and into the Partnership (the “Merger”), with the Partnership surviving and continuing to exist as a Delaware limited partnership.

At the effective time of the Merger (the “Effective Time”), each Common Unit issued and outstanding (other than Common Units owned immediately prior to the Effective Time by Parent and its affiliates, including LP Holdco, which will remain outstanding in the Partnership and be unaffected by the Merger) will be converted into the right to receive $15.85 per Common Unit in cash, without any interest thereon (“Merger Consideration”). In connection with the Merger, (i) the General Partner’s non-economic general partner interest in the Partnership, (ii) the Common Units owned by Parent and its affiliates, including LP Holdco, and (iii) the Series A Preferred Units, shall not be cancelled, shall not be converted into or entitle the holder thereof to receive the Merger Consideration and shall remain outstanding following the Merger as a non-economic general partner interest in the Partnership, as Common Units and as Series A Preferred Units, respectively.

Concurrently with the execution of the Merger Agreement, LP Holdco delivered its written consent covering all of the Common Units and Series A Preferred Units beneficially owned by it approving the Merger Agreement and the transactions contemplated thereby, including the Merger (the “Written Consent”). The Written Consent was sufficient to approve the Merger Agreement and the transactions contemplated thereby, including the Merger, without the receipt of written consents from any other holder of Common Units.

The foregoing summary of the Merger Agreement and the transactions contemplated thereby does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Merger Agreement, a copy of which is filed as Exhibit I hereto and is incorporated by reference in its entirety into this Item 4. The representations, warranties and covenants set forth in the Merger Agreement have been made only for purposes of, were and are solely for the benefit of the parties to, the Merger Agreement, may be subject to limitations agreed upon by the parties to the Merger Agreement and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors. In addition, such representations and warranties (a) will not survive consummation of the Merger and cannot be the basis for any claims under the Merger Agreement by any contracting party after termination of the Merger Agreement, except as a result of intentional and material breach or intentional fraud, and (b) were made only as of the date specified in the Merger Agreement. Moreover, information concerning the subject matter of the representations, warranties and covenants may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in the Partnership’s public disclosures. Accordingly, the Merger Agreement is incorporated by reference herein only to provide investors with information regarding the terms of the Merger Agreement, and not to provide investors with any other factual information regarding the Partnership, Parent or their respective affiliates or businesses. The Merger Agreement should not be read alone, but should instead be read in conjunction with the other information regarding the Merger Agreement, the Partnership, Parent and their respective affiliates and businesses that will be contained in, or incorporated by reference into, the filings that the Partnership makes with the Securities and Exchange Commission.

After the Effective Time, the Common Units will be delisted from the New York Stock Exchange and, as promptly as possible, deregistered under the Act.

Other than as described above, none of the Reporting Persons has any plan or proposals of the type referred to in clauses (a) through (j) of Item 4 of Schedule 13D, although they reserve the right to formulate such plans or proposals in the future.
