Red Robin Gourmet Burgers Closes Amended 5 year $200 Million Credit Facility

Greenwood Village, CO — (BUSINESS WIRE) –December 14, 2005 – Red Robin Gourmet Burgers, Inc. (Nasdaq: RRGB), the casual dining company that serves up fun, feel-good experiences by offering its guests an imaginative selection of high-quality gourmet burgers and innovative menu items in a family-friendly environment, today announced that it has entered into an amended and restated credit agreement with Wachovia Bank, National Association and a syndicate of other financial institutions for an aggregate principal amount of up to $200 million.

The facility also allows the Company an option to increase the facility, subject to lender participation, by up to an additional $40 million in the future. The revolving credit agreement will mature on December 14, 2010. The amended and restated credit agreement replaces the Company’s $85 million senior secured three year revolving credit facility which was scheduled to mature on May 20, 2006. Wachovia Bank, National Association serves as administrative agent for the amended and restated credit facility, while Wachovia Capital Markets, LLC served as lead arranger.

The Company intends to use the proceeds of the facility to finance restaurant construction and related costs, refinance certain existing debt and to provide for working capital and general corporate requirements. The amended credit facility also allows the Company to utilize proceeds to finance potential acquisitions relating to the purchase of Red Robin franchise restaurants.

“We are very pleased to have closed this financing, which will provide us with the flexibility to fund the capital needs of our growing business, and at substantially more favorable rates than under our former facility. The availability of up to $240 million in capital will facilitate our growth plans well into the future,” said Dennis Mullen, Chairman and Chief Executive Officer.

As of the closing date, the Company refinanced approximately $42.1 million outstanding under this facility, including $3.6 million, which the Company uses to back an irrevocable letter of credit for the Company’s self-insured workers’ compensation program.
