      In the May 4, 2007 conference call that Riviera Holdings Corporation
("Riviera" or the "Company") held in conjunction with its release of first
quarter 2007 financial results, William L. Westerman, Chairman of the Board,
President and Chief Executive Officer of Riviera, made the following remarks:

      "We would like to announce that the Company's Board of Directors has
authorized its management to explore a range of strategic and financial
alternatives to enhance shareholder value. These alternatives include, but are
not limited to, a sale of the entire Company. The Company is in the process of
retaining a financial advisor to assist it in this evaluation process. The
Company is extremely mindful of its duty to maximize value for its shareholders.
With respect to the recent, highly conditional merger proposal received from a
group of shareholders for $27.00 per share, we do not believe that this offer is
in the best interests of shareholders, nor do we believe that the recent
nomination of an opposition slate of directors by these same shareholders is
advisable. Rather, we believe that your existing, experienced board is in the
best position to successfully and fairly guide this process and to work to
maximize value for all shareholders. We do not intend to make any comments on
our retention of a financial advisor, the offer or the nomination of an
opposition slate of directors at this time."

FORWARD-LOOKING STATEMENTS

      The foregoing remarks contain forward-looking statements that involve
risks and uncertainties within the meaning of the Private Securities Litigation
Reform Act of 1995. Actual results may differ materially from those expected as
a result of a variety of factors, including those described in our Annual Report
on Form 10-K, a copy of which may be obtained from the Company's website
www.rivierahotel.com or upon request, free of charge, from the Company, 2901 Las
Vegas Boulevard South, Las Vegas, Nevada 89109, Attention: Investor Relations.
Because forward-looking statements are based on a number of beliefs, estimates
and assumptions by management that could ultimately prove to be inaccurate,
there is no assurance that any forward- looking statement will prove to be
accurate.

ADDITIONAL MATTERS

meeting, Riviera has filed a definitive proxy statement on April 16, 2007 with
