FOR IMMEDIATE RELEASE:

                 RIVIERA REPORTS RESULTS FOR FIRST QUARTER 2006

         LAS VEGAS, NV - May 2, 2006 -- Riviera Holdings Corporation (AMEX: RIV)
today reported financial results for the first quarter ended March 31, 2006. Net
revenues for the quarter were $51.7 million, down $775,000 or 1.5 percent from
the first quarter of 2006. Income from operations was $7.8 million, down
$968,000 or 11.1 percent from the first quarter of 2005. Included in operating
income in the first quarter of 2005 was a $1.0 million exclusivity fee from a
prospective purchaser of the Company. Adjusted EBITDA (1) was $11.6 million, in
the first quarter of both 2006 and 2005. Adjusted EBITDA consists of earnings
before interest, income taxes, depreciation, amortization, equity-based
compensation, asset impairments, Sarbanes-Oxley Act expenses and mergers,
acquisitions and development costs, as shown in the reconciliation to net income
in the tables of this release (See Notes 1 and 2 to the Financial Summary

million, or $0.18 per share.

Riviera Las Vegas

         Robert Vannucci, President of Riviera Las Vegas, said, " Although our
first quarter EBITDA was slightly below the prior year's first quarter, it was
our second best first quarter since 2000. The slight decline can be attributed
to a soft Super Bowl week. NFL restrictions, imposed over the past several
years, have limited the activities we can offer which impacted the repeat
business we typically experience during that week.

         Gaming revenues in Las Vegas were down $565,000 in the quarter. This
can be attributed to a soft Super bowl, an increase in convention room nights
mix, a decline in leisure room nights, as well as fewer entertainment covers
(tickets sold).

         "Total room revenues were $14.1 million up $1.4 million, or 11percent
over the same quarter of the prior year. ADR for the quarter was $83.60, an
increase of $10.77 or 15 percent compared to a year ago. Convention room nights
comprised over 37 percent of the total rooms sold in the quarter, an increase of
11.5 percent. Convention room revenue increased by $1.2 million or 21percent
over the first quarter last year and accounted for 47 percent of total room
revenue. We continue to see strong demand for our rooms.

         "The initial gaming revenue results generated by our Westward Ho
marketing agreement, signed in December of last year, have been favorable. We
expect to see this part of our gaming business continue to develop and grow into
the future.

"The Las Vegas market remains strong. Through February of this year, visitor
volumes increased 2.6 percent over last year to 6.1 million visitors. Citywide
occupancy increased 1.7 points to 88.2 percent. Rooms occupied by conventioneers
increased by 4.2 percent to over 3.4 million room nights. Total airline
passengers increased 6.1 percent to over 6.8 million. We believe the market has
fully absorbed the increase in room inventory created by new property openings
and hotel additions."

Riviera Black Hawk

         Ron Johnson, President of Riviera Black Hawk, said, "We are pleased
with first quarter results in Black Hawk. Net revenue, EBITDA and EBITDA margin
were all up over the same period last year. We are particularly pleased that our
EBITDA margin of 31.6 percent grew by 1.6 percentage points during the quarter
compared to the first quarter 2005. Our management team in Black Hawk has done
an excellent job of raising revenues while continuing to effectively manage
marketing expenses.

         "The Black Hawk/Central City market showed gaming revenue growth of 2.8
percent in the first quarter. Black Hawk itself experienced a healthy 4.1
percent growth in gaming revenue. It appears that Black Hawk is showing signs of
recovering some of the market share it lost to Central City after the opening of
Central City Parkway in November 2004."

 Consolidated Operations

William L. Westerman, Chief Executive Officer, said, "I am pleased at the way
management responded to the merger negotiations and overcame the distractions
created by the speculative activity in our stock. EBITDA in this year's first
quarter was consistent with that for the 2005. In the first quarter of 2005, we
reported a negative expense of $667,000, resulting from the failure of a
prospective purchaser to make a bid for the Company at the expiration of an
exclusivity period, which he had been granted in exchange for a $1 million
non-refundable deposit.

         "On April 21, we announced that Duane Krohn, our Chief Financial
Officer, would be retiring effective today. I want to thank Duane for all his
hard work and contributions to the Company over the past 16 years. When I first
came to Las Vegas in 1991 with no experience in the gaming industry, Duane
helped me understand the complexity of the business. He played a major role in
our reorganization in 1993 and our several successful debt offerings. He also
has patiently responded to the many parties who, over the years, have indicated
an interest in acquiring the Company. We wish him good luck and a happy
retirement. Until we find a successor for Duane, the Board of Directors has
appointed me to act as Interim Chief Financial Officer, in addition to my other
duties.

         "We will continue to focus our efforts on operating your Company
effectively to maintain our competitive position and maximize cash flow."

(1)      Adjusted EBITDA consists of earnings before interest, income taxes,
         depreciation, amortization, equity-based compensation, asset
         impairment, Sarbanes-Oxley Act expenses and mergers, acquisitions and
         development costs, net, as shown in the reconciliation to net income
         (loss) in the tables of this release. In 2004, we entered into
         confidential discussions regarding a potential sale of our company.
         Discussions with one potential buyer, which commenced in 2004, ended in
         2005, and we retained a $1 million fee paid to us by that party. Such
         amount is reflected in mergers, acquisitions and developments costs,
         net, for the first quarter of 2005. Adjusted EBITDA is presented solely
         as a supplemental disclosure because we believe that it is 1) a widely
         used measure of operating performance in the gaming industry, and 2) a
         principal basis for valuation of gaming companies by certain investors.
         We use property-level EBITDA (earnings before interest, income taxes,
         depreciation, amortization and corporate expense) as the primary
         measure of the Company's business segment properties' performance,
         including the evaluation of operating personnel. Adjusted EBITDA should
         not be construed as an alternative to operating income, as an indicator
         of our operating performance, as an alternative to cash flows from
         operating activities, as a measure of liquidity, or as any other
         measure determined in accordance with generally accepted accounting
         principles. We have significant uses of cash flows, including capital
         expenditures, interest payments and debt principal repayments, which
         are not reflected in Adjusted EBITDA. Also, other gaming companies that
         report EBITDA or Adjusted EBITDA information may calculate it in a
         different manner than we do. A reconciliation of Adjusted EBITDA to net
         income (loss) is included in the financial schedules accompanying this
         release.
(2)      Adjusted EBITDA margins represent Adjusted EBITDA divided by Net
         Revenues
(3)      These amounts have been adjusted to reflect our three-for-one common
         stock split on March 11, 2005.
