In  the  July  28,  2006  conference  call  that  Riviera  Holdings  Corporation
("Riviera")  will  hold in  conjunction  with  its  release  of  second  quarter
financial  results,  William  L.  Westerman,  Chairman  of the  Board  and Chief
Executive  Officer of Riviera,  will make the following  remarks  concerning the
Agreement and Plan of Merger among Riviera,  Riv  Acquisition  Holdings Inc. and
Riv   Acquisition   Inc.  and  Riviera's   August  8,  2006  annual  meeting  of
shareholders:

     Our proxy  materials in connection  with our annual meeting of shareholders
to be held on August 8, 2006 have been  mailed to  shareholders  of record as of
July 7, 2006.  At the annual  meeting,  shareholders  will vote on,  among other
things, our merger agreement with Riv Acquisition  Holdings Inc. and election of
our  board of  directors.  All  shareholders  should  have  received  our  proxy
materials  directly or through their brokers.  If your shares are held in street
name,  our proxy  materials  should have been  forwarded to you. If you have not
received our proxy materials and you owned shares as of July 7, 2006, I urge you
to  contact  your  broker  immediately  so that you can vote.  Not voting on the
merger will have the same effect as voting  against it because a favorable  vote
of holders of at least 60% of our outstanding shares is required for approval of
the merger.

     Our proxy statement  contains important  information  concerning the merger
and the extensive  process  undertaken by us and our financial advisor to obtain
an acquisition  price which we could recommend for stockholder  approval.  It is
important to understand  that the process to find a purchaser of our company was
initiated in February 2005 and was conducted  over an extensive  period of time.
We were assisted in that process by our financial  advisor,  which made contacts
with over 100 parties,  including gaming  operators,  leisure and  entertainment
companies, private equity firms, and real estate investors, to solicit potential
interest in a purchase of our company.




     Furthermore,  prior  to our  April  6,  2006  announcement  of  the  merger
agreement,  two public reports were issued concerning a possible  acquisition of
Riviera at or above a stated price. On December 27, 2005, my personal  agreement
to sell my Riviera shares to the Riv  Acquisition  Holdings Inc.  investor group
was reported.  That report  informed the public that in addition to acquiring my
shares, the investor group intended to seek to acquire control of Riviera at not
less than $15.00 per share. Thereafter,  on March 23, 2006, Riviera reported its
discussions  with the investor  group for the group's  acquisition of Riviera at
$17.00 per share.  Despite those public reports, no one else came forward with a
credible offer at any price.

     We understand  that certain of our  shareholders  have  suggested  that the
$17.00 per share  price for our stock  should be  restated  and  evaluated  as a
per-acre purchase price for our Las Vegas real estate.  However, it is important
to understand that if you choose to recharacterize  the purchase of our stock as
a purchase of land for redevelopment purposes, significant additional costs must
be considered in calculating  the true  acquisition  price.  These include costs
associated with asbestos abatement,  demolition,  removal of debris, termination
of  employees  and  cancellation  of  leases  and  other  contracts,  especially
convention bookings.  Each of those items would be an additional expense for any
purchaser  that  intends to build an entirely  new  structure on our 26-acre Las
Vegas parcel. We believe those cost factors are particularly  important when you
consider the substantial  development  currently taking place in the vicinity of
Riviera Las Vegas, as well as the age of our facilities.

     Consequently,  we believe that any per-acre pricing analysis must take into
account  the  significant  costs  required to turn our Las Vegas  property  into
vacant,  developable  land.  Put another  way, we believe  that any  prospective
purchaser  contemplating  a  complete  redevelopment  of our  26-acre  Las Vegas
parcel,  rather than an improvement of our existing hotel and casino, would need
to factor those additional costs into the pricing of the deal.

     We have  analyzed a  hypothetical  scenario in which we sell Riviera  Black
Hawk for $125 million, which is the highest price at which a potential purchaser
expressed an interest  during our strategic  process last year, and then we sell
our 26 acres in Las Vegas to a purchaser  who wants  vacant,  developable  land,
similar to the deal  announced by Archon  Corporation  last month for the Wet' n
Wild  property.  We have  concluded  that such a purchaser  would need to pay in
excess  of $17  million  per acre for our Las  Vegas  property  in order for our
shareholders  to realize a net $17.00 per share price.  Our analysis is based on
the following cost factors and the  purchaser's  assumption or retirement of our
debt:

    o  Riviera's effective federal tax rate is 35%
    o  Riviera's effective Colorado tax rate is 4.63%
    o  Our tax basis in Riviera Black Hawk is $53 million
    o  Our tax basis in Riviera Las Vegas' assets including land is $106 million
    o  $56.5 million of federal tax net operating losses are available without
       regard to Internal Revenue Code section 382 limitations
    o  In order to turn Riviera Las Vegas into vacant, developable land, costs
       associated with demolition, abatement, WARN Act compliance and personnel
       severance, as well as the cost of canceling our committed convention
       sales contracts and lease agreements must be factored into the pricing of
       the deal. Our rough estimate of the total of those costs is at least $36
       million, although it is difficult to calculate an actual total prior to
       occurrence of such an event.

     I want to stress that after considering all the relevant factors, Riviera's
board of directors  concluded  that $17.00 per share was the best price we could
obtain for the company,  and it continues to be the best price we can obtain for
the company.  Therefore,  we recommend  that  shareholders  vote in favor of the
merger.

     You should also  consider  that after we  announced on November 8, 2005 the
termination of our strategic process to maximize shareholder value, the price of
our stock fell below  $15.00 per share and did not climb  above that level until
after the report on December  27, 2005 of my  agreement to sell my shares to Riv
Acquisition Holdings Inc.'s investor group at $15.00 per share.

     Our annual  meeting  will be held at the  Riviera  Las Vegas on August 8 at
11:00 a.m. We hope shareholders will attend in person or by proxy.
