                      EXECUTIVE DEFERRED COMPENSATION PLAN


     Pinnacle Entertainment, Inc., a Delaware corporation formerly known as

continued growth, development and future business success of the Company.

     B.  By Section 12.2 of the Plan, the Company has reserved the right to
amend the Plan.

     C.  It is possible that, if a Change in Control (as defined in the Plan)
occurs, certain individuals who are Participants in the Plan will become
entitled to receive, under the terms of the agreements pursuant to which such
Change in Control is consummated, cash payments in consideration of the
cancellation of stock options which they hold in the Company (the "Option

     portion of such Option Cancellation Payment by delivering to the Committee
     a completed and signed Election Form, which Election Form (a) may be
