                        INVESTOR GROUP ANNOUNCES SLATE OF
                         INDEPENDENT BOARD NOMINEES FOR
                                RIVIERA HOLDINGS

                 Group Cites Current Board's Lack of Objectivity

LAS VEGAS, NEV, April 27, 2007 - While continuing efforts to resolve its issues
with the current Board of Directors of Riviera Holdings Corporation (AMEX: RIV),
Riviera stockholders affiliated with Riv Acquisition ("Riv Acquisition") have
announced they will nominate a slate of independent directors for consideration
at the gaming company's Board election scheduled for May 15, 2007. As part of
the process, the group has asked the company for a list of all shareholders
eligible to vote.

In a letter delivered to Riviera on April 26, the group identified the following
individuals as nominees for consideration at the company's upcoming Board
election currently scheduled for May 15, 2007:

Thalia M. Dondero - Former three-term chair of the Clark County Commission,
serving as a commissioner for 20 years. Currently serving on the Board of
Regents and Investment Committee of the University of Nevada, Las Vegas, on the
Board of Trustees of Summerlin Hospital and on the Resource Advisory Council of
the Nevada Bureau of Land Management.

Larry duBoef - Past President of the American Cancer Society. Also, former
President of Western Linen Las Vegas and former President of Unicom, a Western
U.S. radio station operator. Previously a consultant to Taj Mahal Casino in
Atlantic City and to Aztar Corp.

W. Dan Reichartz - Principal of DR&DR, Limited Partnership, a private firm that
provides strategic planning, concept and design development, marketing and
management services to the gaming, hotel and resort industry. Former President
and Chief Operating Officer for Caesar's Palace Hotel and Casino, former Vice
President and General Manager of the Waldorf Astoria Hotel in New York City.

Michael D. Rumbolz - Chairman and Chief Executive Officer of Cash Systems, Inc.,
a publicly listed provider of cash access services to the casino industry. Also
Owner and Managing Director of Acme Gaming LLC, a firm providing development,
merger, acquisition, strategic planning, legal compliance and other services to
businesses involved in the gaming industry. Former executive and/or board member
for several gaming companies. Also, former Chairman of the Nevada State Gaming
Control Board.

Daniel Yih - Portfolio Principal and Chief Operating Officer of GTCR Golder
Rauner, LLC, a private equity firm. Former General Partner of Chilmark Partners,
L.P., another private equity firm. Member of the Board of Directors of Starwood
Hotels & Resorts Worldwide, Inc., one of the world's leading hotel operators,
since August 1985.

Today's announced actions follow Riv Acquisition's March 26 merger proposal to
Riviera Holdings for $27 per share. Riviera's Board cited purported obstacles to
its consideration of the proposal, and stated that Riv Acquisition is prevented
from engaging in the merger with Riviera, based on Riviera's articles of
incorporation and Nevada corporate statutes. Riv Acquisition has challenged the
Board's stated rationale, leading to its recent decision to seek a ruling from
the Clark County District Court on the matter.

Riv Acquisition consists of Paul C. Kanavos and Robert Sillerman, the managing
members of New York-based Flag Luxury Properties, LLC, Las Vegas developer Brett
Torino, and Starwood Capital Group Chairman and CEO Barry Sternlicht.

On behalf of the group, Mr. Kanavos said, "In or view, Riviera's Board, in its
statements and actions of the last month, has demonstrated a lack of objectivity
in the way it has addressed our offer for the company. We are nominating this
outstanding group of completely independent individuals with the hope of
bringing objectivity to the process of considering our offer, along with any
other offers that may surface. These nominees bring impeccable credentials and
reputations to the company -- with deep roots in the local community, the gaming
industry and the lodging sector."
