      The Reporting Persons have entered into a Fifth Amended and Restated Joint
Filing Agreement, dated as of May 3, 2007, a copy of which was filed as Exhibit
10.20 to the Statement, and which is incorporated herein by reference. Neither

admission by the Reporting Persons that they constitute a "group" as such term
is used in Section 13(d)(1)(k) of the rules and regulations under the Securities

ITEM 1.  SECURITY AND ISSUER

      Response unchanged.

ITEM 2.  IDENTITY AND BACKGROUND

      Response unchanged.

ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

      Response unchanged.

ITEM 4.  PURPOSE OF TRANSACTION

      Item 4 is hereby supplemented as follows:

      On May 16, 2007 Paul Kanavos sent a letter to the Board (the "May 16, 2007
Letter"), on behalf of an investing group led by Mr. Kanavos, Robert Sillerman,
Brett Torino and Barry Sternlicht (the "Investment Group"), proposing to
acquire, through a merger transaction with the Investment Group's acquisition
vehicles, all of the issued and outstanding Company Stock at a price of $34.00
per share ("Merger Transaction"). The May 16, 2007 Letter states that the
Investment Group is prepared to enter into a merger agreement with the Company
on substantially the same terms as the April 5, 2006 merger agreement between
the Investment Group's acquisition vehicles and the Company. The Investment
Group is prepared to provide the Board with assurances for the necessary debt
financing to complete the proposed Merger Transaction, and the Investment Group
is committed to provide all necessary equity financing for the proposed Merger
Transaction.



      The Investment Group is also prepared to include a "go shop" provision in
the proposed merger agreement pursuant to which the Company could solicit and
engage in discussions and negotiations with respect to competing proposals for a
15 day period. If the Company were to terminate the proposed merger agreement
because it received a superior proposal during the "go shop" period, the
Investment Group would not be entitled to any additional break-up fee but would
only be entitled to reimbursement for its expenses in connection with the
proposed Merger Transaction, up to a reasonable limit.

      The conditions to close the proposed Merger Transaction would be
substantially the same as those contained in the April 5, 2006 merger agreement.
The Investment Group will not require a financing condition to closing the
proposed Merger Transaction and the only significant third-party condition to
closing the proposed Merger Transaction is the obtaining of all necessary gaming
approvals from the gaming authorities in Nevada and Colorado.

      The conditions to closing the proposed Merger Transaction will not
restrict the Company's ability to refinance its outstanding secured notes,
provided that the refinancing is made on market terms and without prepayment
penalty, defeasance or premium. The proposed merger agreement is not intended to
restrict the Company's ability to conduct its business in the ordinary course
while the proposed Merger Transaction is pending.

      The Investment Group intends to repay all of the Company's outstanding
indebtedness of the Company upon completion of the proposed Merger Transaction.
The Investment Group is prepared to honor the salary continuation packages
currently in place that have been negotiated with management as well as the
change-of-control provisions in all currently outstanding stock option awards.

      The Investment Group indicates in the May 16, 2007 Letter that if Board
does not respond to its proposal by 5:00 PM PST on May 17, 2007, then it will
assume that the Board does not wish to discuss its proposal any further.

      There can be no assurance that any such proposed Merger Transaction can be
negotiated. The Reporting Persons may, at any time and from time to time,
review, reconsider or change their plans or proposals with respect to the
foregoing, or terminate such discussions.

      The foregoing and subsequent references to, and descriptions of, the May
16, 2007 Letter, are qualified in their entirety by reference to such letter,
the contents of which are incorporated herein by reference to Exhibit 10.23
hereto.

ITEM 5.  INTEREST IN SECURITIES OF THE COMPANY

      Response unchanged.

ITEM  6.  CONTRACTS,  ARRANGEMENTS,   UNDERSTANDINGS,  OR  RELATIONSHIPS  WITH
RESPECT TO SECURITIES OF THE COMPANY.

      Item 6 is hereby supplemented as follows:

      21. On May 16, 2007, Paul Kanavos submitted the May 16, 2007 Letter to the
Board, the contents of which are described in Item 4 herein. A copy of the May
16, 2007 Letter is filed herewith as Exhibit 10.23 and incorporated herein by
reference.

ITEM 7.  MATERIAL TO BE FILED AS EXHIBITS.



      Item 7 is hereby supplemented as follows:

      10.23   Letter, dated May 16, 2007 from Paul Kanavos to the Board of
              Directors of Riviera Holdings Corporation.



                                    SIGNATURE

      After reasonable inquiry and to the best of my knowledge and belief, I
