Luminex Named one of Los Angeles Area's Fastest Growing Technology Companies in Deloitte Technology Fast 50 Program for Fourth Consecutive Year

Luminex Attributes Its Innovative Storage Technologies to Its 114% Revenue Growth Over the Past Five Years

Riverside, Calif., September 29, 2005 - Luminex Software, Inc., a leading developer of data storage products, has been named to Deloitte's prestigious Technology Fast 50 Program for the Los Angeles/Inland Empire area, 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 revenue growth over the five years from 2000-2004.

Luminex's increase in revenues of 114% from 2000 to 2004 resulted in a 34th ranking in the 2005 Technology Fast 50 for the Los Angeles/Inland Empire area.

Art Tolsma, CEO of Luminex, credits Luminex's dedication to developing innovative storage technologies as the stimulus behind the company's fast growth over the past five years. Tolsma continues: "Luminex is proud to be named to the Deloitte Fast 50 program for the fourth year in a row. We are excited to build on our solid foundation of continued revenue growth and profitability."

"Deloitte's Los Angeles Technology Fast 50 companies have shown the strength, vision and temerity to succeed in today's very competitive technology environment," said Tim Lovoy, partner of Deloitte's Technology, Media & Telecommunications Group. "We applaud the successes of Luminex and acknowledge their place as one of the very few to accomplish such a fast growth rate over the past five years."

To qualify for the Technology Fast 50, companies must have had operating revenues of at least $50,000 in 2000 and $1,000,000 in 2004, must be public or private companies headquartered in North America, and be a "technology company," defined as a company that owns proprietary technology that contributes to a significant portion of the company's operating revenues or devotes a significant proportion of revenues to research and development of technology. Using other companies' technology in a unique way does not qualify.

Winners of the 15 regional Technology Fast 50 programs in the United States and Canada are automatically entered in Deloitte's Technology Fast 500 program, which ranks North America's top 500 fastest growing technology companies.
