Green Mountain Coffee Roasters Announces Asset Purchase Agreement for

Acquisition of the Tully’s Coffee Brand and Wholesale Business

West Coast Acquisition to Accelerate GMCR’s Geographic Expansion Plans

Company Intends to Leverage Full Potential of Complementary Tully’s brand to drive

Keurig^® Single-Cup Brewing system penetration across North America

WATERBURY, VT (September 15, 2008) – Green Mountain Coffee Roasters, Inc. (NASDAQ: GMCR) announced today that the Company has executed an Asset Purchase Agreement to acquire the Tully’s coffee brand and wholesale business from Tully’s Coffee Corporation for a cash purchase price of $40.3 million, subject to adjustment at closing. Tully’s wholesale business division distributes handcrafted coffees and related products via office coffee services, food service distributors, and over 5,000 supermarkets located primarily in the western states.

Tully’s Coffee Corporation will remain an independent company, owned by its existing shareholders and managed by its existing management team, with a focus on its retail and international division assets. Tully’s retail business will operate under license and supply agreements with GMCR. This arrangement is intended to create consistent representation of the Tully’s brand while providing high quality gourmet coffee to all customers drinking Tully’s branded coffee.

Following the completion of this transaction, GMCR expects to integrate approximately 70 employees from Tully’s wholesale business into its Green Mountain Coffee segment. GMCR will sublease from Tully’s the portion of Tully’s manufacturing and distribution center in Seattle, WA that is devoted to the wholesale business.

Green Mountain Coffee intends to finance the purchase through its existing $225 million senior revolving credit facility. This transaction is subject to customary closing conditions, including approval by Tully’s shareholders, and is expected to close by the end of calendar 2008. Tom T. O’Keefe, Chairman of the Board of Tully’s, representing 10.4 % of the outstanding voting shares and 20.1% of the common stock outstanding of Tully’s, has agreed to vote in favor of the transaction.

Green Mountain Coffee anticipates the acquisition will be neutral to modestly accretive to its earnings per share for the first twelve months of ownership following the closing of the transaction, and accretive thereafter. Taking into account the acquisition, the Company is not changing its previously issued estimates for fully diluted GAAP earnings per share in the range of $1.20 to $1.30 per share for fiscal year 2009.

Lawrence J. Blanford, President and CEO of Green Mountain Coffee Roasters, said, “GMCR is delighted to be adding an outstanding specialty coffee brand such as Tully’s to our coffee roasting family. Tully’s will provide GMCR with a complementary West Coast brand and business infrastructure, furthering our plans to establish the Company, and its proprietary Keurig^® Single-Cup Brewing system, throughout North America.”

Blanford continued, “Tully’s wholesale sales over the past 12 months ended June 30, 2008 of $30.4 million are up approximately 35% driven by growing supermarket distribution to 5,000 doors in 20 states, primarily in the western part of the nation, and K-Cup^® portion pack sales. This complements our own business in these channels, which is currently largely on the East Coast. Enhanced distribution of Tully’s K-Cup portion packs in supermarkets and office coffee services also presents exciting opportunities. Tully’s has been a Keurig licensee since November, 2005. With this acquisition, we intend to further leverage the brand’s potential and aggressively grow Tully’s wholesale business.”

Blanford concluded, “We have great admiration for the Tully’s brand and commitment to the community which the founder, Tom T. O’Keefe, has created. We believe Tully’s wholesale business is a compelling and strategic acquisition. It will further strengthen GMCR’s ability to better service its customers and deliver enhanced shareholder value over time.”

Ropes & Gray LLP served as legal advisor to GMCR for this acquisition.
