Craig Miller, President and CEO of Ruth’s Chris Steak House, made the following comments concerning the acquisition. “In 1976 our founder Ruth Fertel entered into a partnership with Mr. Thomas J. Moran, a successful Baton Rouge businessman. Mr. Moran went on to become Ruth’s Chris Steak House’s largest and most successful franchisee, developing Ruth’s Chris restaurants in many Midwest and Southeast markets throughout the 1980’s and 1990’s. Mr. Moran has been a major contributor to the successful history and growth of the Ruth’s Chris family of restaurants and we are pleased T.J. will maintain his relationship with the company by continuing to own and operate our legendary Baton Rouge restaurant over the next several years”. Miller added “The franchise acquisition we’ve announced today is an exciting step for the company. Not only will the transaction be immediately accretive to shareholders but the size and demographics of each market allow for significant future development and will enhance the long term growth potential for our shareholders.” Miller continued “as we assimilate these restaurants into our company operated base, we will proceed with our previously announced growth plans opening an additional four to five company units during the remainder of 2006.”

The Company will comment on the acquisition in its earnings release and conference call to be held today, Monday, April 24, 2006.
