Onyx Software to Introduce IBM AIX5L-Based CRM Solution
Offering Expands Business Relationship, Creates Cost-Effective Solution for UNIX Market

BELLEVUE, Wash. — Onyx® Software Corp. (Nasdaq: ONXS) today announced a new IBM AIX5L-based version of its customer relationship management (CRM) suite for large and medium-sized enterprises. This latest version of Onyx Enterprise CRM 4.0 includes support for Oracle database applications running on IBM eServer pSeries systems. The solution is currently in its final testing stage before general availability.

Onyx Enterprise CRM 4.0, the fourth generation of Onyx’s Internet-based CRM suite, is built entirely on standards-based Internet technologies including XML. It is completely Web-based, integrates fully with other enterprise applications, and is designed with usability and cost-effectiveness in mind.

"Over the past 12 months, Onyx and IBM have established a strong relationship that spans the services, hardware and software aspects of our businesses," said Eben Frankenberg, executive vice president of Onyx Software. "Delivery of Onyx Enterprise CRM 4.0 on the IBM AIX platform is a key component of this partnership and will enable Onyx and IBM to address a broader portion of our joint market."

The introduction of Onyx Enterprise CRM 4.0 for IBM AIX5L builds on the growing relationship between Onyx and IBM. Last fall, the two companies announced a collaborative effort to provide enterprise CRM solutions to midmarket customers; the relationship now touches multiple IBM lines of business, including Business Innovation Services, IBM eBusiness hosting within the IBM Global Services unit, the IBM Software Group for WebSphere and MQ Series, and IBM eServer xSeries.

"The Onyx customer relationship management solution is a valuable addition to the broad portfolio of leading applications running on AIX5L," said Mike Kozel, IBM eServer alliance executive, Server Group. "The combination of Onyx 4.0 and IBM eServer pSeries systems provides our joint customers with a cost-effective, flexible, high-performance platform."
