Explanation of Responses:

( 1 )Pursuant to that certain Agreement and Plan of Merger, dated August 15, 2023, by and among the Issuer, HF Sinclair Corporation ("DINO") and the other parties thereto, the Issuer became an indirect, wholly owned subsidiary of DINO on December 1, 2023 upon the closing of the transactions contemplated therein (the "Closing"). Upon the Closing, each outstanding common unit representing a limited partner interest in the Issuer (each, a "Partnership Common Unit") was converted into the right to receive (a) 0.315 shares of common stock, par value $0.01 per share, of DINO, with cash paid in lieu of the issuance of fractional shares, if any, and (b) $4.00 in cash, without interest. As a result, REH Company (f/k/a The Sinclair Companies) and Mrs. Holding ceased to own any Partnership Common Units effective upon the Closing.

Remarks: Mark Petersen currently serves as REH's representative on the Issuer's board of directors, and therefore REH and Mrs. Holding each constitute a "director by deputization" of the Issuer.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
