Luminex Software Named One of Los Angeles Area's Fastest Growing Technology Companies in Deloitte & Touche Technology Fast 50 Program

Attributes 19th Ranking to its 496% Revenue Growth

Riverside, CA, September 10, 2003 - Luminex Software, Inc., a leading developer of data distribution, archiving and storage products, has been named to Deloitte & Touche's prestigious Los Angeles Technology Fast 50 program, a ranking of the 50 fastest growing technology companies in the area by Deloitte & Touche LLP, one of the nation's leading professional services firms. Rankings are based on the percentage of growth in fiscal year revenues over five years, from 1998-2002.

"To succeed during prosperous times is one thing; to succeed in adversity is much more challenging, and that's exactly what the Deloitte & Touche Technology Fast 50 winners have done," said Gary Dickey, partner in the Technology, Media & Telecommunications group, Deloitte & Touche. "We applaud Luminex for its tremendous accomplishments during economically challenging times and for being one of the elite Fast 50 companies in the Los Angeles area."

Arthur Tolsma, Luminex's CEO, attributes the company's increased ranking in the 2003 Los Angeles Technology Fast 50 program to teamwork and shared commitment: "Luminex's continued success is due to a company-wide focus on our strategic vision of innovation and customer service, and commitment to revenue growth and profitability. I look forward to even higher growth rates and increased recognition in the coming years."

Luminex's increase in revenues of 496 percent from 1998 to 2002 resulted in a 19th ranking overall in the 2003 Los Angeles Technology Fast 50. Luminex's position in last year's 2002 Los Angeles Technology Fast 50 was 21st ranking overall.

To qualify for the Technology Fast 50, companies must have had operating revenues of at least $50,000 in 1998 and $1,000,000 in 2002, must be public or private companies headquartered in North America, 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 portion of revenues to research and development of technology.

This year's Los Angeles Technology Fast 50 program is co-presented by Deloitte & Touche, Focus Creative, Marsh, Shaw Pittman, and in association with AeA, and Software Council of Southern California.

Winners of the 20 regional Technology Fast 50 programs in the United States and Canada are automatically entered in the Deloitte & Touche Technology Fast 500 program, which ranks North America's top 500 fastest growing technology companies.
