BELLEVUE, Wash. - Powering enterprises with proven customer relationship management (CRM) solutions and established IT consulting expertise, Onyx® Software Corporation (NASDAQ: ONXS) has expanded its relationship with IBM to include IBM Global Services CRM Solution Services.

As part of this relationship, IBM and Onyx will initially focus on providing enterprise CRM solutions that deliver rapid ROI to mid-market customers. The two companies will leverage IBM's deep industry, analytical and integration expertise to provide CRM solutions based on Onyx's third-generation Internet architecture application suite.

IBM's Business Innovation Services organization will train a select group of experienced consultants in both Canada and the United States to deliver the Onyx CRM solutions. Initially, both IBM and Onyx personnel will staff projects, providing the necessary domain expertise for successful implementations.

"Our relationship with IBM adds another dimension to our ability to deliver enduring business value to our customers," said Eben Frankenberg, executive vice president of Onyx. "With IBM's leadership and global reach, we believe Onyx will be able to more aggressively pursue a greater number of international projects. Whether it is building an enterprise IT platform, integrating to back office ERP systems, or powering your Web site with a leading CRM platform, IBM's expertise can maximize a company's investment in Onyx."

With more than 149,000 professionals on staff and over $30 billion in revenues, IBM Global Services is the world leader in providing IT services. The company is also a world leader in delivering end-to-end e-business and CRM services to the marketplace. Already a leader in technology hosting, IBM is investing billions over the next three years to expand its hosting infrastructure, which currently includes 230 data centers across the globe.

Via the data centers in North America, IBM will offer Onyx applications in a hosted environment to customers looking to outsource their CRM needs. In addition, Onyx has partnered with the IBM eServer xSeries brand to ensure that the Onyx Product Suite runs optimally on IBM's affordable Intel-based servers. IBM's xSeries servers provide scalable, industry standard architecture with outstanding performance, manageability, reliability, and compatibility. Onyx's XML-based CRM software is IBM ServerProven, signifying that it has been tested and certified on IBM's Intel-based server family.

"Both Onyx and IBM have proven track records in delivering successful and affordable enterprise CRM projects across a broad range of industries," said Bryan Berent, Global Midmarket Sell and Support Solutions Executive of IBM Global Services. "The two organizations bring together powerful capabilities that enable rapid implementations and significant return on investment for customers. Combining IBM's extensive industry and technology capabilities and global reach with the ease of integration, scalability and robustness of the Onyx solution, we can approach mutual Midmarket customers from a position of strength."

"IBM has the technology and skills to help customers build a high-availability scalable platform and accelerate application deployment, eliminating the need for the customer to act as the systems integrator," said Frankenberg. "IBM is extremely qualified to provide Onyx customers a single source solution for their CRM strategic application implementation and IT infrastructure requirements."
