Michael D. Rumbolz, Larry duBoef, W. Dan Reichartz and Daniel W. Yih and Ms. Thalia M. Dondero for election to the Board at Riviera's 2007 Annual Meeting. Our primary objective in nominating an alternative slate of directors has always been the maximization of value for all shareholders. Now that the Board has indicated that it will seek to maximize shareholder value, we believe that replacing the Board is not necessary at this time. We expect that the Board will conduct an open and fair process and that it will give due consideration to all expressions of interest prior to entering into a definitive agreement for a sale of the company. Consistent with this, we expect that the Board will allow our group to participate in the process on an equal footing with other bidders, will consider all potential structures for an acquisition of the company, and will no longer raise technical objections to proposed transaction structures as it has in the past. Our group is currently considering all of its options, which may include making a higher offer than the $30 per share expression of interest that the Board announced on May 11. Given the Board's past characterization of our group's unconditional merger proposal as "highly conditional", we request prompt disclosure of the specific terms of this new expression of interest. As you know, our group is the largest shareholder of the company. We believe that shareholders will hold the Board accountable if it does not act consistently with its stated course of pursuing maximum value for all shareholders. Very truly yours, FLAG LUXURY RIV, LLC By: /s/ Paul Kanavos ------------------------------------ Name: Paul Kanavos Title: President
