Section 7 - Regulation FD

Item 7.01 Regulation FD Disclosure.

     On April 13, 2006, Riviera Holdings  Corporation (the "Company") was served
with a class  action  complaint  that was filed in the  District  Court of Clark
County,  Nevada  (Case  No.  A520136)  in the name of Todd  Veeck,  on behalf of
himself and all other similarly situated  shareholders,  against the Company and
its directors on April 7, 2006. The complaint refers to the plaintiff as being a
shareholder of the Company at all relevant times.






         The plaintiff alleges, among other things, that the defendants breached
their fiduciary duties owed to the Company's shareholders by entering into the
Agreement and Plan of Merger, dated April 5, 2006 (the "Merger Agreement"),
among the Riv Acquisition Holdings Inc., Riv Acquisition Inc. and the Company at
a price that the plaintiff considers to be inadequate.

         The plaintiff requests, among other things, that the court (i) order
that the action may be maintained as a class action and certify the plaintiff as
the representative of the class consisting of all Company shareholders, other
than the defendants and any person or entity related to or affiliated with any
of them, (ii) enjoin consummation of the merger contemplated by the Merger
Agreement or order rescission of the merger if it is consummated and (iii)
direct the defendants to account to the class members for damages.

         The Company believes the plaintiff's allegations are without merit.

         The information in this Item 7.01 shall not be deemed "filed" for
purposes of Section 18 of the Exchange Act, nor shall it be deemed incorporated
by reference in any filing under the Securities Act, except as and when
expressly set forth by such specific reference in such filing.
