November 14, 2008-Catalyst today announced that it has been named a member of Deloitte's 2008 Fast 500, a ranking of the 500 fastest growing technology, media, telecommunications and life sciences companies in North America. Rankings are based on percentage of fiscal year revenue growth over five years.

"We are excited to be ranked among the 500 fastest growing technology companies in the US and to be recognized again by Deloitte for our achievements," said John Tredennick, Catalyst's founder and CEO. "We have worked hard to stay at the forefront of e-discovery trends and deliver the technology that allows legal teams to review and manage documents quickly and effectively."

This marks Catalyst's second appearance on the Fast 500. Catalyst was also listed on Deloitte's Colorado Fast 50 for the fourth year in a row, which includes every year in which it has been eligible.

Prior to its rankings on the Colorado Fast 50 and the national Fast 500, Deloitte recognized Catalyst as a Rising Star, a special designation for especially promising companies that have been in business a minimum of three years, but
not more than five years.

"Deloitte's Technology Fast 500 recognizes companies who have achieved extraordinary growth in North America's most innovative and competitive market sectors," said Phil Asmundson, Deloitte LLP vice chairman and national managing partner for Technology, Media and Telecommunications. "We congratulate Catalyst on this significant accomplishment."

Fast 500 Selection and Qualifying Criteria

The Fast 500 ranks the fastest growing technology, media, telecommunications and life sciences companies in North America. It is compiled from Deloitte's regional North American Fast 50 programs, nominations submitted directly to the Fast 500, and public company database research. Companies are selected based on percentage revenue growth from 2003 to 2007.

Entrants must own proprietary intellectual property or proprietary technology that contributes to a significant portion of the company's operating revenues or devote a significant proportion of revenues to research and development of technology. Using other companies' technology or intellectual property in a unique way does not qualify. Base-year operating revenues must be at least $50,000 USD or $75,000 CD, and current-year operating revenues must be at least $5 million USD or CD. Companies must be in business a minimum of five years, and they must be headquartered within North America.
