          Amendment to Memorandum of Understanding and Letter of Intent

Dear Sirs:

      Reference is made to the Memorandum of Understanding and Letter of Intent
dated as of September 2, 1997 (the "Letter of Intent"), between us and you.
Terms used but not defined in this letter agreement have the meanings assigned
thereto in the Letter of Intent.

      You and we hereby agree that the last sentence of the first paragraph and
the section under the caption "Exclusive Period" in the Letter of Intent shall
be deleted in their entirety. You and we also agree that the following sections
shall be added at the end of the Letter of Intent immediately prior to the
signature block:

"Binding Agreement;               The parties will use their best efforts       
Documentation:                    promptly to complete and execute all          
                                  agreements and other documents that may be    
                                  reasonably necessary to carry out the         
                                  provisions of this MOU. Such agreements will  
                                  contain, among other things, such terms,      
                                  covenants, representations, warranties and    
                                  conditions as are customary for transactions  
                                  of this nature. However, it is expressly      
                                  agreed that our agreement set forth in this   
                                  MOU is not conditioned upon the signing of any
                                  such agreements or other documents, but is    
                                  intended to create a legally binding          
                                  obligation of each of us, subject only to the 
                                  conditions that (i) on or prior to December   
                                  31, 1997, the LLC shall have obtained written 
                                  proposal(s) from one or more lenders with     
                                  respect to at least $120 million of           
                                  conventional construction financing at an     
                                  interest rate not                             


                                  exceeding 10% per annum and containing such
                                  other terms, covenants, representations,
                                  warranties and conditions as are customary for
                                  transactions of this nature (the "Financing")
                                  and (ii) on or prior to March 31, 1998, the
                                  LLC shall have obtained written commitment(s)
                                  from one or more lenders to provide the
                                  Financing.

Purchase Right and                If (a) either party, any beneficial owner of  
Indemnity in Event of             an interest in either party, or any officer or
Licensing Problem:                director of either party is denied a gaming   
                                  license or is found unsuitable or unqualified 
                                  to have a gaming license pursuant to a        
                                  determination by the Nevada Gaming Authorities
                                  and (b) such problem is not cured within 30

                                  Authorities) to purchase the entire interest  
                                  of such party in the LLC at a price equal to  
                                  the fair market value of such interest (as    
                                  determined by a qualified independent         
                                  appraiser). Each party will indemnify the     
                                  other party from and against all losses,      
                                  claims, damages and liabilities arising out of
                                  or based upon any determination by the Nevada 
                                  Gaming Authorities referred to in clause (a)  
                                  above (whether or not final).                 

Disputes:                         If any controversy, dispute or claim shall
                                  arise under this MOU, such controversy,
                                  dispute or claim shall be determined by
                                  arbitration conducted in New York City, before
                                  one arbitrator and in accordance with the
                                  then-existing Rules for Commercial Arbitration
                                  of the American Arbitration Association (the
                                  "Rules"), and any judgment or award rendered
                                  by the arbitrator shall be final, binding and
                                  unappealable, and judgment may be entered by
                                  any court having jurisdiction thereof. The
                                  parties hereby agree to the institution of any
                                  available "fast track" or other mechanisms or
                                  procedures that would have the effect of
                                  streamlining or increasing the speed of the
                                  arbitration. The parties hereto intend that
                                  the provisions to arbitrate set forth herein
                                  be valid, enforceable and irrevocable. In his
                                  award the arbitrator shall allocate, in his
                                  discretion, among the parties to the
                                  arbitration at all costs of the arbitration,
                                  including the fees and expenses of the
                                  arbitrator and reasonable attorneys' fees,
                                  costs and expert witness expenses of the
                                  parties. The parties hereto agree to comply
                                  with any award made in any such arbitration
                                  proceedings that has become final in
                                  accordance with the Rules and agree to the
                                  entry of a judgment in any jurisdiction upon
                                  any award rendered in such proceedings
                                  becoming final under the Rules. The arbitrator
                                  shall be entitled, if appropriate, to award
                                  any remedy in such proceedings, including
                                  monetary damages, specific performance,
                                  temporary restraining order, preliminary
