QRS Diagnostic Named One of Fastest Growing Technology Companies

MINNEAPOLIS – October 1, 2004 – QRS Diagnostic, leader in innovative design and development of software-based medical devices in computer cards, announced today that it ranks 26th in Deloitte’s prestigious Technology Fast 50 Program for Minnesota, a ranking of the fifty fastest growing technology companies in the area by Deloitte & Touche LLP, one of the nation’s leading professional services firms. Rankings are based on percentage growth in fiscal year revenues over five years, from 1999 to 2003. QRS grew its revenues by 233 percent to attain its ranking.

“This is the second consecutive year that we’ve made the Fast 50 list,” said Spencer Lien, chief executive officer, QRS. “Integration of our computer card medical device technology with electronic medical record systems and other enterprise health care IT systems has opened new opportunities for business partnerships. And with our U.S. and international patents, QRS continues to grow our distribution channels and expand sales in Europe, Australia and Japan.”

“To make the Deloitte Technology Fast 50, companies in Minnesota must have achieved tremendous revenue growth from 1999 to 2003,” said Ron Hafner, partner, Deloitte & Touche LLP. “Deloitte applauds QRS Diagnostic for having the long-term vision to develop technology that delivers on its promise.”

To qualify for the Minnesota Technology Fast 50, companies must have had operating revenues of at least $50,000 in 1999 and $1,000,000 in 2003, must be public or private companies headquartered in Minnesota, and be a “technology company” defined as owning proprietary technology that contributes to a significant portion of the company’s operating revenues (using other companies’ technology in a unique way does not qualify); and/or devoting a significant proportion of revenues to research and development of technology.

Winners of the 18 regional Technology Fast 50 programs in the United States and Canada are automatically entered in the Deloitte Technology Fast 500 program, which ranks North America’s top 500 fastest growing technology companies.
