Section 7 - Regulation FD

Item 7.01 Regulation FD Disclosure.

         On April 19, 2006, a class action complaint (the "Silva Complaint") was
filed in the District Court of Clark County, Nevada (Case No. A520638), which
complaint is identical to the complaint filed on April 6, 2006 (the "Trozzi
Complaint") and the complaint filed on April 7, 2006 (the "Labarbara Complaint")
that Riviera Holdings Corporation (the "Company") reported in its April 10, 2006
Form 8-K and April 11, 2006 Form 8-K, respectively, except that the named
plaintiff in the Silva Complaint is Norberto Silva. Also, one of the plaintiff's



three law firms in the Trozzi Complaint is not in the Silva Complaint and only
one of the plaintiff's three law firms in the Labarbara Complaint is in the
Silva Complaint. The Silva Complaint was served on the Company on April 21,
2006.

         On April 24, 2006, the Company was notified that the Trozzi Complaint
was dismissed by the plaintiff without prejudice.

         The Company believes the allegations in the complaints are without
merit.
         The information in this Item 7.01 shall not be deemed "filed" for
purposes of Section 18 of the Exchange Act, nor shall it be deemed incorporated
by reference in any filing under the Securities Act, except as and when
expressly set forth by such specific reference in such filing.
