                             RESTRUCTURING AGREEMENT
                             -----------------------

     THIS RESTRUCTURING AGREEMENT (the "Agreement"), dated as of May 13, 2002,
is made by and among Jonathan Ungar ("Ungar"), Alan Henry Woods ("Woods"; and
together with Ungar, the "Note Holders") and Venture Catalyst Incorporated, a
Utah corporation (the "Company").

                                    RECITALS
                                    --------

     A. The Note Holders are the holders of those certain Promissory Notes made
by the Company which are listed on Exhibit A hereto (the "Notes").
                                   ---------

     B. L. Donald Speer, II ("Speer") owns all of the outstanding shares of
capital stock of Speer Casino Marketing, Inc., a Delaware corporation ("Speer
Corporation").

     C. Speer has expressed an interest in negotiating with the Special
Committee of the Board of Directors of the Company a merger transaction (the
"Merger") which would have the effect of taking the Company private and in which
the shareholders of the Company would, in exchange for their shares of common
stock of the Company, receive cash plus the right to receive additional
contingent consideration. Speer currently contemplates that in connection with
the Merger the Company would merge with and into Speer Corporation, with Speer
Corporation being the surviving corporation.

     D. Speer and the Note Holders contemplate that as a condition precedent to
the consummation of the proposed Merger, the Company and the Note Holders would
agree to restructure the indebtedness represented by the Notes.

    E. In contemplation of the proposed Merger, the Note Holders and the Company
desire to restructure the indebtedness represented by the Notes (the
"Restructuring") by canceling the Notes, and all outstanding principal and
accrued and unpaid interest thereunder, and entering into this Agreement,
pursuant to which the Company will issue to the Note Holders the Class A
Contingent Promissory Notes in substantially the same form as attached hereto as
Exhibit B (the "Contingent Notes"), pursuant to which the Company would make
---------
principal payments to the Note Holders in amounts based on the Gross Revenues
(as defined in the Contingent Notes) of the Company.

     F. The Note Holders and the Company desire to enter into this Agreement to
set forth the terms and conditions of the Restructuring.
