RIVER ROCK ENTERTAINMENT AUTHORITY TO OFFER $205 MILLION OF SENIOR NOTES DUE 2018

        Geyserville, CA. October 19, 2011—The River Rock Entertainment Authority (the "Authority"), the operator of the River Rock Casino in Sonoma County, California, today announced its intention to offer, pursuant to exemptions from registration under the Securities Act, $205.0 million aggregate principal amount of Senior Notes due 2018 (the "New Notes").

        The Authority intends to use the proceeds from the offering of the New Notes, together with cash on hand and the proceeds from a concurrent private placement of $27.6 million of 6.50% Senior Subordinated Notes due 2019, to retire all of our outstanding 9³/4% Senior Notes due 2011 and the Tribe's outstanding notes and to fund the construction of an emergency access road over the Tribe's reservation and a portion of newly acquired property.

        This press release is not an offer to sell or the solicitation of an offer to buy any securities. The New Notes have not been registered under the Securities Act or the securities laws of any other jurisdiction. Unless they are registered, the New Notes may be offered only in transactions that are exempt from registration under the Securities Act or the applicable securities laws of any other jurisdiction. The New Notes are being offered in the United States only to "qualified institutional buyers" (as defined in Rule 144A under the Securities Act) and outside the United States to non-U.S persons in reliance on Regulation S under the Securities Act.
