The Leading European Computer Company Leverages

Vendor-Independent Integration Solution for Rapid Deployment

and Lower Total Cost of Ownership

Siebel Systems, Inc. (Nasdaq:SEBL), the world's leading provider of eBusiness applications software, today announced that Fujitsu Siemens Computers, the leading European computer company, will leverage Universal Application Network to improve integration between its front office customer relationship management (CRM) solutions from Siebel Systems and multiple disparate back office systems from a variety of vendors. Universal Application Network provides Fujitsu Siemens Computers with a standards-based, vendor-independent application integration solution that transforms application integration from a complex and expensive technical challenge into the strategic ability to implement customer-facing business processes across and beyond the enterprise.

Launched by Siebel Systems in April 2002, Universal Application Network represents an innovative new paradigm for multi-application integration. It is the first and only standards-based, best-in-class solution that fully meets the key objectives of enabling organizations to deploy end-to-end, industry-specific business processes while reducing the cost, complexity, and time of cross-application integration. In addition, these business processes are application-independent and can be deployed across a diverse set of applications across multiple divisions and business units. The result is a customer-centric solution that dramatically reduces the need for customization, minimizes complexity, speeds deployment, and delivers a low total cost of ownership.

Fujitsu Siemens Computers implements the Siebel eBusiness Applications since 2001 as one of the largest CRM projects in Europe. More than 2,300 sales and service professionals in 23 countries and 5 languages will use Siebel Sales, Siebel Call Center, and Siebel Partner Relationship Management (PRM) to manage sales pipeline reporting, forecasting, activity assignment, telephone-based marketing, quote and proposal generation, and detailed performance reporting. This integrated CRM solution provides the company with a closed-loop system for identifying, acquiring, and retaining profitable customers and serving them even faster. Siebel eBusiness Applications also enable the company to streamline the order process and place a greater focus on high-value customers.

Fujitsu Siemens Computers' CRM solution includes point-to-point integration of its SAP R/3, BaaN, i2, and other disparate back office systems with Siebel eBusiness Applications. With multiple applications and systems in 23 countries and 5 languages, Fujitsu Siemens Computers recognizes the need to move beyond point-to-point integration to a more enterprise-spanning integration strategy. Universal Application Network provides Fujitsu Siemens Computers with a standards-based solution that reduces the need for customization, minimizes complexity, speeds deployment, and delivers a low cost of ownership.

"Universal Application Network is exactly the architecture that will enable a rapid integration of our internal and customer-facing applications at a very low cost while giving us maximum flexibility," says Kai Flore, CIO Fujitsu Siemens Computers. "By focusing on our strategic goals for eCRM and accelerating the integration with our SAP and other back office systems, Universal Application Network enables the company to deliver a highly focused market penetration strategy, streamline the order management process, and help us increase revenue. The Siebel eBusiness Applications deployment will pay for itself in 18 months, which is a rate of return that any executive would like to see. Furthermore, we provide customers with our Siebel CRM implementation knowledge and experience using our platforms and IT infrastructures, Flore says.

Fujitsu Siemens Computers uses its own state-of-the-art hardware at all stages of the eBusiness initiative. The company has gained invaluable experience in many areas, including the development of the technical architecture, sizing, scalability, and performance, which was recently demonstrated with Siebel Systems to more than 30 jointly invited customers at a showcase event in Munich, Germany. With application integration the number one challenge for customers' CRM applications, the event highlighted how this customer-centric, standards-based solution enables organizations to deploy end-to-end, industry-specific business processes while dramatically lowering the cost, complexity, and time to deployment.
