ABeam Selects Onyx as a Preferred CRM Solution; ABeam to promote Onyx customer process solutions in Japan.

BELLEVUE, Wash. -- Onyx(R) Software Corporation (Nasdaq:ONXS) today announced an alliance agreement with ABeam Consulting Corporation, a leading global consulting firm headquartered in Japan. Under the terms of the alliance, ABeam will promote and provide consulting services for Onyx's customer process solutions to the Japanese market in conjunction with ABeam's leading IT consulting services and methodology.

Prior to the agreement, Onyx and ABeam had teamed together on three significant customer implementations in Japan, including a successful call center implementation at a leading insurance company.

"Our clients have increasingly asked for comprehensive customer and process management solutions that will help them design, execute, and manage their customer related processes more effectively," said Gregory Ascolese, Principal of CRM Group, ABeam Consulting. "The Onyx solutions give us the ability to deliver those capabilities, and do so on a platform that is both scalable and flexible. That flexibility gives us the opportunity to blend the application with our best practices knowledge and create a solution that fits the unique business needs of our clients."

With this alliance, Onyx and ABeam will partner to provide an integrated offering of services and software - everything from strategic review and business process re-engineering, to project scoping and the implementation of Onyx' customer process software. Onyx' strengths in automating, managing, and evolving customer processes are already being used with ABeam's Customer Management Value Framework, which charts out the value of an enterprise's customer-related processes. ABeam will work with Onyx to train its consultants on the Onyx portfolio of products to enhance ABeam's total solution implementation skills. To accelerate sales efforts, ABeam has created an "Onyx Center of Excellence" at its main office in Tokyo that includes multiple live use case scenario prototypes and a customer training facility.

"We are very pleased to work with ABeam, a company that is well-known for having deep experience in IT projects and providing high-caliber consulting services," said Andie Rees, Senior Vice President, International. "The enterprise software knowledge and experience that ABeam brings, combined with their management consulting skills, allows them to provide customers with a comprehensive suite of services. We believe that this partnership will allow us to serve a broader segment of the Japan market and allow both companies to better meet customers' needs."
