                       AMENDMENT NO. 2 TO LOAN AGREEMENT
                       ---------------------------------


          THIS AMENDMENT NO. 2 TO LOAN AGREEMENT (this "Amendment"), dated as of
January 31, 2001, is executed with reference to the Loan Agreement dated as of
June 30, 1999, among Detroit Entertainment, L.L.C., a Michigan limited liability
company ("Borrower"), the Lenders named therein, and Bank of America, N.A.
(formerly known as Bank of America National Trust and Savings Association), as
Issuing Lender and Administrative Agent, as amended by Amendment No. 1 to Loan
Agreement dated as of September 30, 2000 (as so amended, the "Loan Agreement").

                                    RECITALS
                                    --------

A.   Borrower has heretofore incurred $37,680,493 of Indebtedness (the
     "Intercompany Indebtedness") in favor of Circus Circus Michigan, Inc.
     ("CCMI"), a Michigan corporation which is a wholly-owned subsidiary of
     Mandalay Resort Group (the "Company").

B.   While Borrower, CCMI and the Company intended that the Intercompany
     Indebtedness be treated as Company Subordinated Debt, they did not comply
     with the Loan Agreement's requirement for that treatment by failing to
     execute a Subordination Agreement in the form of Exhibit I to the Loan
     Agreement and by failing to obtain the approval of the instruments
     governing the Intercompany Indebtedness.

C.   Borrower has requested that Lenders waive such failures and amend the Loan
     Agreement as set forth below to revise the Maximum Total Debt Ratio
     restrictions set forth in Section 6.12 of the Loan Agreement.


          NOW, THEREFORE, the parties agree as follows:

     1.   Defined Terms.  All initially capitalized terms used in this Amendment
          -------------
without definition shall have the respective meanings assigned thereto in the
Loan Agreement.  In addition, the definition of "Company Subordinated Debt" set
forth in Section 1.1 of the Loan Agreement is hereby amended to read in full as
follows [with the text added thereto being set forth herein in underscored and
italicized text for the convenience of the readers]:

          "Company Subordinated Debt" means Indebtedness of Borrower to the
           -------------------------
     Company or any of its wholly-owned Subsidiaries having a final maturity
             ---------------------------------------
     which is after the Maturity Date, having no payments of principal due prior
                                                          ------------
     to that maturity date except to the extent that the making of such payments
                           -----------------------------------------------------
     does not result in the failure of Borrower to be in pro forma compliance
     ------------------------------------------------------------------------
     with the terms hereof, which is subject to a Subordination Agreement, and
     ---------------------
     which has representations, warranties, covenants and defaults which are no
     less favorable to the Company and such wholly-owned Subsidiaries than those
                                   ----------------------------------
     contained herein and which are otherwise acceptable to the Administrative
     Agent.

                                                                    -----------

     --------------------------------------------------------------------------

     ----------------------------

     3.   Waiver re Intercompany Indebtedness.  The Lenders waive the failure of
          -----------------------------------
