Onyx ranked as one of the world's largest software companies

Bellevue, Wash. -- Onyx Software Corporation (Nasdaq: ONXS), a leading provider of enterprise-wide, customer-centric e-business applications, today announced it has been named to Software Magazine's Software 500 list. The list, featured in the June / July 2000 edition, ranks the world's foremost software and services providers. Onyx ranked 198 with software revenue of $60.6 million.

"This year we made our debut on the Software 500 by leap-frogging over 300 contenders. That sort of growth can come only from having the right vision and delivery capabilities for the market," said Brent Frei, president and CEO of Onyx Software. "Our vision is all about helping companies win in the Internet economy by bringing e-business and business together. For companies everywhere, it's a race to combine bricks and clicks in a way that serves customers best and achieves a competitive advantage. We think we do this better than any company in the world, and the tremendous growth that gained us entry on this list is a validation of our vision."

"Ever-increasing R&D-spending by the Software 500 companies is fueling the Internet economy," said John Desmond, Software Magazine's editorial director. "The CIOs, senior IT and e-business managers who read Software Magazine value this unique issue as a yearly benchmark of the standing of their product and service partners. And each year, as suppliers consolidate and new markets emerge, the composition of the Software 500 ranking reflects those changes."

Software Magazine's annual compendium of software and services suppliers catalogs the ranking, financial performance and growth, and primary business sector for each company as well as trend information for the Software 500 as a whole. The Software 500 is a comprehensive look at the enterprise software landscape, encompassing both public and private companies that develop business software and services. The ranking is based on total worldwide software and services revenue for 1999. Suppliers are not ranked on their total corporate revenue, since many others have other lines of business. Software revenue includes license fees, as well as maintenance and support revenue, professional services/consulting, and custom programming. The financial information is based on the calendar year and was gathered from Software Magazine's vendor survey, public documents and industry analysts.
