Item 1.01     Entry into a Material Definitive Agreement

         On August 22, 2007, Delek US Holdings, Inc. ("Delek") entered into a
registration rights agreement with TransMontaigne, Inc. ("TMG") as part of the
completion of the acquisition described in Item 2.01 below. The registration
rights agreement entitles TMG to demand one registration of the Delek Shares (as
defined in Item 2.01 below) at any time between July 7, 2008, and August 22,
2017.

Item 2.01     Completion of Acquisition or Disposition of Assets

         On August 22, 2007, Delek US Holdings, Inc. ("Delek") completed the
acquisition of approximately 28.34% of the issued and outstanding shares of
common stock, par value $0.10 per share (the "Lion Shares"), of Lion Oil Company
("Lion Oil") from TMG, the Joseph Hansley Bander Family Trust, the Estate of
Frederick R. Mayer, Jerry D. Armstrong, Ray O. Brownlie, James B. Wallace and
Rex Utsler (together with TMG, collectively, the "Sellers"). Total cash
consideration paid by Delek to the Sellers was approximately $65.4 million. In
addition to cash consideration, Delek issued 1,916,667 unregistered shares of
Delek common stock, par value $0.01 per share (the "Delek Shares"), to TMG.

         TMG is a wholly-owned subsidiary of Morgan Stanley Capital Group Inc.

Delek Marketing & Supply, LP, engage in the purchase and sale of crude oil and
refined products with Morgan Stanley.

Item 8.01.    Other Events

        (i)   On August 22, 2007, Delek entered into a definitive stock purchase
agreement to acquire additional Lion Shares for a purchase price of
approximately $23 million. The shares to be purchased equal approximately 6.24%
of the issued and outstanding Lion Shares. The closing of the transaction is
subject to customary closing conditions and governmental approvals, and is
anticipated to close during the third quarter of this year. Subsequent to
Delek's completion of the transaction, Delek will own approximately 35% of the

and its affiliates are a lender, administrative agent or arranger with respect
to credit facilities involving the Company's wholly-owned subsidiary, MAPCO
Express, Inc. ("MAPCO"). The amendment, among other things, made certain changes
to the credit facility to permit the acquisition of the Lion Shares described in
