FOR IMMEDIATE RELEASE:

           RIVIERA HOLDINGS CORP. ANNOUNCES RECEIPT OF BID TO ACQUIRE
                       COMPANY FOR $30 PER SHARE IN CASH

    RETAINS JEFFRIES & COMPANY AS FINANCIAL ADVISOR TO EXPLORE STRATEGIC AND
                             FINANCIAL ALTERNATIVES

      LAS VEGAS, NEVADA (MAY 11, 2007) - RIVIERA HOLDINGS CORPORATION (AMEX:
RIV) today announced that it has received a bid for $30 per share in cash from a
group led by Ian Bruce Eichner and Dune Capital Management LP. The Eichner
Group's bid represents an 11% premium over a competing bid of $27 per share
which had been received from a dissident investor group led by Riv Acquisition
Holdings, which has also nominated an opposition slate of nominees for election
as directors at the Company's upcoming annual meeting scheduled for May 15,
2007. The Riv Acquisition group is currently soliciting proxies in support of
its handpicked nominees, and has stated that if its nominees are elected, it
will resubmit its proposal to acquire the Company.

      William Westerman, Chairman of the Board of the Company, stated, "We are
not surprised to receive a bid substantially higher than the Riv Acquisition
group's below market bid. We continue to believe that $27 per share does not
represent full value for our stockholders, which we believe is confirmed by both
the Company's current market price ($31.85 close on May 10, 2007) as well as by
this current $30 per share offer. The Board intends to fully consider the $30
Eichner Group bid and review it with our advisors."

      Mr. Westerman continued, "Your Board is committed to working for all
stockholders. We will insure that all bidders are given a level playing field,
with the Board's goal to maximize value for all stockholders."

      As previously announced, Riviera has retained Jefferies & Company, Inc. as
its financial advisor to assist it in exploring a range of strategic and
financial alternatives in order to maximize stockholder value. These
alternatives include, but are not limited to, a sale of the entire Company. As
its financial advisor, Jefferies will assist the Company in reviewing this new
$30 per share proposal.




      Riviera recently mailed proxy material to stockholders in which the Board
recommended that stockholders use the WHITE Proxy Card to:

      o  Vote "FOR" the re-election of five experienced Directors: William L.
         Westerman, Jeffrey A. Silver, Paul A. Harvey, Vincent L. DiVito and James
         N. Land Jr.

      THE DIRECTORS PROPOSED BY THE BOARD ARE HIGHLY QUALIFIED INDIVIDUALS WITH
RELEVANT EXPERIENCE, AND ARE COMMITTED TO MAXIMIZING VALUE FOR ALL STOCKHOLDERS.

                SIGN, DATE AND RETURN THE WHITE PROXY CARD TODAY

      THE BOARD URGES STOCKHOLDERS TO SUPPORT RIVIERA BY COMPLETING, SIGNING AND
DATING THE WHITE PROXY CARD AND PROMPTLY MAILING IT IN THE POSTAGE-PAID ENVELOPE
PROVIDED WITH THE PROXY MATERIALS. THE BOARD FURTHER URGES STOCKHOLDERS NOT TO
SIGN OR RETURN THE BLUE PROXY CARD THAT WAS SENT TO STOCKHOLDERS BY THE RIV
ACQUISITION GROUP AND ITS ASSOCIATES.

      Whether or not stockholders plan to attend the Meeting, and regardless of
the number of shares stockholders own, the Board urges you to vote FOR the
Board's nominees.
