21,051% Growth Rate Attributed to Focus on Core Values

Bellevue, Wash. -- Onyx Software Corporation (NASDAQ: ONXS), a leading provider of Web-based customer relationship management software, has been named the fastest growing technology company in Washington state in Deloitte & Touche's prestigious "Fast 50" Program. Rankings for the awards are based on revenue growth over a five-year period. From 1994 to 1998 Onyx's revenue grew 21,051%.

Onyx Software President & CEO Brent Frei credits Onyx's focus on core values of innovative Web product development, successful delivery, and a strong company culture as critical to the company's success. "There's no question that revenue growth is the foremost yardstick by which technology companies are measured. We love being #1 in one of the world's hottest technology regions, where there are more than 2,000 technology companies," said Frei. "What we're even more proud of, however, is that we achieved our number one ranking without sacrificing customer or employee satisfaction. Lots of companies can grow revenue fast. What's tough is growing it fast while setting the industry standard for customer satisfaction and creating an award-winning work environment. We've focused on building the best products in the market, implementing them quickly and successfully, and having fun while we do it. We're pleased that we've been rewarded for our continued dedication to these core values."

"In an era where technology companies come and go like shooting stars, winning the Deloitte & Touche 'Fast 50' is a testament to Onyx Software's leadership and its ability to not only have the right solution for customers, but also the vision and culture which combined achieve spectacular growth," said Larry Hile, Partner, Deloitte & Touche. "Onyx has proven that they have the right stuff to succeed, and we at Deloitte & Touche salute the company's accomplishments."

Winners of the 19 regional Fast 50 programs in the United States are automatically entered in the Deloitte & Touche Technology Fast 500 program, which ranks the nation's top 500 fastest-growing technology companies.
