Calico Commerce, Inc. (Nasdaq:CLIC), a leading provider of software that enables corporations to control eBusiness selling, has been named to Deloitte & Touche's prestigious "Fast 50" Program for Silicon Valley, a ranking of the 50 fastest growing technology companies in the area.

Calico Commerce ranked fourteenth overall. Rankings are based on the percentage of growth in revenues from 1995-1999 (five-year period).

"Today, there are more than 22,000 technology companies in the United States, many of whom are competing for the same markets here in the states and worldwide. The Fast 50 winners for Silicon Valley have proven they can compete successfully by consistently delivering technological wonders. We at Deloitte & Touche commend Calico Commerce for having the vision and determination to become one of the 50 fastest growing technology companies in Silicon Valley," said Roy Avondet, partner in charge of Technology & Communications for Northern California, at Deloitte & Touche in San Jose, CA.

Calico's increase in revenues of 6,592 percent over the five-year period of 1995 to 1999 resulted in a fourteenth ranking overall in the Fast 50 for Silicon Valley. The average increase in revenues among companies who made the Fast 50 for this region was 7,142 percent. National average for all 19 regions was 3,554 percent. "It's a great honor for Calico to be listed on the Fast 50 for Silicon Valley, and I consider this a tremendous tribute to the accomplishments of our employees," said Alan Naumann, president and CEO, Calico Commerce. "Our dramatic increase in revenue can be attributed to consistently meeting the eBusiness challenges of today's leading corporations and continuing to provide the most comprehensive selling solution on the market today to enable our customers to improve sales, stay competitive and increase profit margins." To qualify for the Fast 50, companies must have had revenues of at least $50,000 in 1995 and at least $1,000,000 in 1999; must be public or private companies headquartered in the region; and be "technology companies" defined as companies that produce technology, manufacture a technology product, are technologically intensive, use technology in problem-solving, or devotes a high percentage of effort to research and development of technology.
