SUNSTONE HOTEL INVESTORS, INC. ANNOUNCES OFFERING OF $220,000,000

EXCHANGEABLE SENIOR NOTES DUE 2027

San Clemente, Calif. (June 11, 2007) – Sunstone Hotel Investors, Inc. (NYSE: SHO), sole managing member of Sunstone Hotel Partnership, LLC (the “Operating Company”), announced today that the Operating Company has commenced a private offering, subject to market conditions, of $220 million aggregate principal amount of exchangeable senior notes due 2027. The notes will be senior unsecured obligations of the Operating Company and, subject to certain designated events and other conditions, exchangeable into, at the Operating Company’s option, cash, Sunstone common stock or a combination of cash and Sunstone common stock. The notes will be guaranteed by Sunstone and certain subsidiaries of Sunstone. The interest rate, exchange rate and other terms of the notes will be determined by negotiations between the Operating Company and the initial purchasers of the notes. To the extent additional notes are fungible for U.S. Federal income tax purposes with the notes, the Operating Company has granted an option to the initial purchasers to purchase up to an additional $30 million aggregate principal amount of notes at the offering price less the discount within 30 days of the initial issuance of the notes solely to cover over-allotments.

Sunstone intends to use the net proceeds from this private offering and other working capital to repay and/or defease the $175 million loan on the Hyatt Regency Century Plaza Hotel and repurchase up to $60.2 million (or $89.6 million if the initial purchaser’s option to purchase additional notes is exercised in full) of its common stock concurrently with the offering. The stock

repurchase is part of a repurchase program approved by Sunstone’s board under which Sunstone may purchase up to an aggregate of $100 million of its common stock prior to December 31, 2007. Any open market repurchases will be conducted in compliance with the Securities and Exchange Commission’s Rule 10b-18 and applicable legal requirements and shall be subject to market conditions and other factors.

The notes will be sold to qualified institutional buyers in reliance on Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”). The notes, the guarantees and any Sunstone common stock that may be delivered upon exchange of the notes have not been registered under the Securities Act or any state securities laws, and unless so registered, may not be offered or sold in the United States except pursuant to an exemption from the registration requirements of the Securities Act and applicable state laws. This press release shall not constitute an offer to sell or the solicitation of an offer to buy any of these securities, nor shall it constitute an offer, solicitation or sale in any jurisdiction in which such offer, solicitation or sale is unlawful.
