Section 2 - Financial Information
Item 2.02 - Results of Operations and Financial Condition.

         On May 2, 2006, Riviera Holdings Corporation ("Riviera") announced
through a press release its first quarter 2006 financial results. A copy of the
press release disclosing those results is furnished as Exhibit 99 hereto. The
information in this Item 2.02 and Exhibit 99 hereto shall not be deemed "filed"
for purposes of Section 18 of the Securities Exchange Act of 1934, nor shall it
be deemed incorporated by reference in any filing under the Securities Act of
1933, except as and when expressly set forth by such specific reference in such
filing.


Section 8 - Other Events
Item 8.01 - Other Events.

         William L. Westerman, Riviera's Chairman and Chief Executive Officer,
will make the following opening remarks in the May 2, 2006 conference call to be
held in conjunction with Riviera's release of first quarter financial results:

o    As many of you know, on April 6, 2006, Riviera announced its agreement to
     be acquired for $17 per share by Riv Acquisition Holdings Inc., which is
     owned by an investor group led by Neil Bluhm, Barry Sternlicht, Brett
     Torino and Paul Kanavos.

o    Since April 6, 2006, there has been speculation in the media and in the
     trading of Riviera's stock at levels well in excess of the agreed buyout
     price. We know of no reason for such speculation other than the recent
     heightened bidding activities related to another casino operator, Aztar
     Corporation, and certain public statements by one of Riviera's larger
     stockholders.

o    We encourage all stockholders to review the proxy statement regarding
     Riviera's transaction with Riv Acquisition Holdings Inc. and its investment
     group when the proxy statement becomes publicly available.  It will contain
     important information concerning the contemplated transaction, including
     the background of the transaction and the extensive process undertaken by
     Riviera and its financial advisor to get an acquisition price for Riviera,
     which we could recommend for stockholder approval.  In the meantime, it is
     important to understand that the process was conducted over several months,
     and Riviera was assisted in the process by its financial advisor, which
     made numerous contacts with third parties who were viewed as potential
     strategic or financial buyers.  Furthermore, since we announced on March
     23, 2006 our discussions with the investor group for a possible acquisition
     of Riviera at $17 per share, no other credible offers have emerged at any
     price.

o    We will not take any questions on the acquisition transaction on this
     earning call.

o    Again, we encourage you to read the proxy materials when they become
     publicly available.

o    I will now present my prepared remarks on the recent earnings and operating
     performance of Riviera.

o    Once again I wish to remind you that we will not be taking any questions on
     the proposed acquisition transaction with Riv Acquisition Holdings Inc.
     and the investor group.

ADDITIONAL INFORMATION AND WHERE TO FIND IT

         The information in this Item 8.01 may be deemed solicitation material
with respect to the proposed acquisition of Riviera through a merger with Riv
Acquisition Inc., which is a wholly-owned subsidiary of Riv Acquisition Holdings
Inc. In connection with that proposed merger, Riviera will file a proxy
statement and other materials with the Securities and Exchange Commission (the
"SEC"). INVESTORS AND SHAREHOLDERS ARE URGED TO READ THE PROXY STATEMENT AND
OTHER MATERIALS WHEN THEY BECOME AVAILABLE BECAUSE THEY WILL CONTAIN IMPORTANT
INFORMATION ABOUT THE PROPOSED TRANSACTION. Riviera and its officers and
directors may be deemed participants in the solicitation of proxies in
connection with the proposed transaction. Information regarding such individuals
is included in Riviera's proxy statement relating to its 2005 annual meeting of
stockholders previously filed with the SEC, and will also be included in the
proxy statement relating to the merger when it becomes available. Investors may
obtain a free copy of the proxy statement relating to the merger and other
relevant documents when they become available, as well as other proxy statements
and materials concerning Riviera filed with the SEC, at the SEC's website at
www.sec.gov. Free copies of Riviera's SEC filings are also available on
Riviera's internet website at www.theriviera.com.
