Luminex Software Named One of the Fastest Growing Technology Companies in North America on the 2003 Deloitte Technology Fast 500

Attributes its 496% Revenue Growth to Technology Innovation

Riverside, CA, October 14, 2003 - Luminex Software, Inc., a leading developer of data distribution, archiving and storage products, today announced that it ranked Number 481 on the 2003 Deloitte Technology Fast 500, a ranking of the 500 fastest growing technology companies in North America. Rankings are based on average percentage revenue growth over five years, from 1998-2002. Luminex grew 496% during this period.

"Attracting enough customers to maintain triple digit growth over five years makes a strong statement about the quality of a company's product and its leadership," said Mark Evans, national managing partner of Deloitte's Technology, Media & Telecommunications Group. "Luminex has shown the right stuff for growth."

Luminex's CEO, Arthur Tolsma, credits the company's 496% revenue growth over the past five years to streamlined execution of the company's core values of technology innovation, exceptional customer service and commitment to both revenue growth and profitability. He said: "Luminex's high growth rates are a direct result of our dedication to leveraging unique technologies; thus, delivering greater value to our customers."

"Growing the top line enough to make the Deloitte Technology Fast 500 is especially meaningful during tough economic times for the technology sector," added Mr. Evans. "We congratulate Luminex on becoming one of the 500 fastest growing technology companies in North America."

In addition to ranking on the Deloitte Technology Fast 500, Luminex Software ranked Number 19 on the Los Angeles Technology Fast 50, which is a ranking of the 50 fastest growing technology firms in Los Angeles.

Fast 500 Selection and Qualifications

The Fast 500 list is compiled from Deloitte's 20 regional North American Fast 50 programs, nominations submitted directly to the Fast 500, and public company database research. To qualify for the Fast 500, entrants must have had 1998 operating revenues of at least $50,000 USD and $75,000 CD for the United States and Canada, respectively; and 2002 operating revenues must be at least $1 million USD or CD. Deloitte researchers examined financial statements to validate operating revenues.

Entrants must also be public or private companies headquartered in North America and must 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 the research and development of technology. Using other companies' technology in a unique way does not qualify.
