On June 19, 2006, a complaint (the "Consolidated Complaint") captioned "In Re Riviera Holdings Corporation Shareholders' Litigation" was filed against Riviera Holdings Corporation (the "Company") and its directors in the District Court of Clark County, Nevada (the "Court") (Case No. A520100), as a consolidation of the class action complaints that the Company reported in its Form 8-Ks furnished to the Securities and Exchange Commission on April 11, 17, 25 and 28, 2006 (the "Prior Complaints"). The Consolidated Complaint was served on the Company on June 20, 2006 pursuant to a Stipulation and Pretrial Order entered by the Court, and is substantially similar to the Prior Complaints. The plaintiffs request the Court to do the following, among other things: (i) declare that the case is maintainable as a class action; (ii) declare that the Agreement and Plan of Merger, dated April 5, 2006 (the "Merger Agreement"), among Riv Acquisition Holdings Inc., Riv Acquisition Inc. and the Company is unlawful; (iii) enjoin consummation of the merger contemplated by the Merger Agreement "unless and until the Company adopts and implements a procedure or process to obtain the highest possible price for shareholders"; (iv) direct the defendants to disclose all material information before seeking shareholder approval of "any acquisition;" and (v) impose a constructive trust, in favor of the plaintiffs, on any benefits improperly received by the defendants. The Company believes the allegations in the Consolidated Complaint and the Prior Complaints are without merit. The information in this Item 7.01 shall not be deemed "filed" for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, except as and when expressly set forth by such specific reference in such filing.
