SEPATON Named Rising Star in Deloitte's Technology Fast 500 Program.

Significant Year-Over-Year Growth Ranks Company Among Fastest Growing Companies in North America

MARLBOROUGH, Mass. -- SEPATON, Inc. has been named a Rising Star in Deloitte's 2007 Technology Fast 500. A special category, the Rising Star list ranks 20 companies that have been in

business a minimum of three years, but less than five years. They are ranked based on percentage of fiscal year revenue growth over three years (2004 to 2006). Deloitte's Technology Fast 500 is a ranking of the 500 fastest growing technology, media, telecommunications and life sciences companies in North America.

"It is a great achievement for SEPATON to be ranked as one of the fastest growing companies in North America, a distinction we attribute to our stellar technology development, attention to customers' distinct needs and our commitment to innovation," said Mike Worhach, SEPATON's president and CEO. "With 690% growth rate, we are well positioned to take a leadership role in the exploding storage backup and recovery market with solutions such as ContentAware[TM] data de-duplication and virtual tape that continue to outperform the competition's offerings. We are well-positioned to continue this great momentum."

"To be honored as a Deloitte Technology Fast 500 Rising Star, young companies must have achieved tremendous revenue growth over three to four years," said Phil Asmundson, vice chairman, U.S. Technology, Media and Telecommunications, Deloitte & Touche USA LLP. "Deloitte applauds SEPATON for earning their spot as one of the Rising Stars for 2007."

SEPATON's scalable and performance-leading enterprise-class data de-duplication and virtual tape solutions have accelerated the company's growth by 690% during the past three years. The company's technology now protects over 800 customers worldwide with over 30 PB of data. Healthcare, financial services and government markets have yielded strong growth for the company and internationally, SEPATON is expanding rapidly in EMEA and APAC. SEPATON solutions are based on its ContentAware software architecture, an intelligent core with the power to distinguish content and files. This platform enables SEPATON to extend the functionality of its virtual tape library product line with its breakthrough ContentAware data protection applications. ContentAware applications provide powerful data protection capabilities that deliver unparalleled time-savings and efficiency.

To qualify as a Fast 500 Rising Star, entrants must have had 2004 operating revenues of at least $50,000 USD or $75,000 CD, for the United States and Canada, respectively, and 2006 operating revenues of at least $5 million USD or CD.

Entrants must be headquartered in North America, and own proprietary technology or proprietary intellectual property that contributes to a significant portion of the company's operating revenues, or devote a significant proportion of revenues to the research and development of technology. Using other companies' technology or intellectual property in a unique way does not qualify.
