WELLESLEY, MA, November 20, 2000 - DYS Analytics, Inc. today announced that the company ranked 175th on the Deloitte & Touche Technology Fast 500, a ranking of the 500 fastest-growing technology companies in North America. Rankings are based on five-year percentage revenue growth from 1995-1999.

DYS Analytics, Inc.'s CEO Marco Farsheed credits the growing recognition of the critical importance of messaging and groupware networks as a key driver in the company's revenue growth over the past five years. "Companies are depending more and more on electronic messaging & groupware, for internal and external communications. We are growing because senior management teams now recognize the strategic role of messaging and groupware within their organizations and the need for providing appropriate service levels. DYS is helping these organizations improve their service levels while reducing their infrastructure costs," said Farsheed. "We are building our business by meeting a demand in the global market."

"With its ranking on the prestigious Deloitte & Touche Technology Fast 500, DYS Analytics, Inc. leaders have proven that they have the vision and the fortitude to excel in the highly competitive technology industry," said Mark A. Evans, managing director of Deloitte & Touche's Technology & Communications Group. "We congratulate them on becoming one of the 500 fastest-growing technology companies in the U.S. and Canada."

In addition to ranking on the Deloitte & Touche Technology Fast 500, DYS Analytics, Inc. ranked 14 on the New England Technology Fast 50, which is a ranking of the 50 fastest-growing technology firms in New England.
