SeeBeyond and Siebel Systems Extend Strategic Alliance to Lower Total

Cost of Integration

SeeBeyond (Nasdaq:SBYN), the leading global provider of eBusiness and Application Integration (eAI) solutions, today announced that it has developed the ability to run key Universal Application Network business processes using the SeeBeyond(TM) Business Integration Suite. Leveraging this capability and working closely with Siebel Systems, Inc. (Nasdaq: SEBL), a leading provider of multichannel eBusiness applications software, SeeBeyond has demonstrated the ability to import Siebel Systems' key business processes for Universal Application Network. In addition, Infonet Services Corporation announced its endorsement of Siebel Systems' key Universal Application Network business processes running on the SeeBeyond Business Integration Suite.

"Responding and adapting to rapidly changing business dynamics, while simultaneously managing growth and new product rollout, are top priorities for Infonet," said Jim deMin, Channel Marketing Manager for Infonet. "Focused on improving customer satisfaction and ensuring continued growth, we need tightly integrated technology that enables rapid and cost-effective deployment of our solutions. Universal Application Network running on the SeeBeyond Business Integration Suite will help us implement efficient Order Management business processes and allow us to meet our goals of becoming the provider of choice, the business partner of choice, and a key influencer in the evolution of today's global communications marketplace."

As organizations such as Infonet need to unify myriad disparate business processes and applications, integration is one of the key corporate constraints on revenue growth, increased productivity, and business performance visibility. Universal Application Network takes a standards-based approach to the design and development of end-to-end business processes that are now executable on the SeeBeyond platform. In addition, these business processes are application-independent and can be deployed across a diverse set of applications that span multiple divisions and business units. Based on XML and Web Services industry standards, Universal Application Network enables organizations to select best-in-class applications and ensures that they are not locked into vendor-specific proprietary architectures. Universal Application Network includes three primary components:

-- Best-Practice Business Process Library -- A library of prepackaged industry-specific business processes based on best practices. These prebuilt, quality-assured business processes, provided by Siebel Systems, can be executed across multiple applications, departments, organizations, and enterprises.

-- Business Process Design Tools -- A selection of business process design tools, provided by leading integration server vendors, for modeling and configuring existing business processes and creating new ones.

-- Integration Server -- An integration server to execute business processes and coordinate interapplication communication.

The SeeBeyond Business Integration Suite demonstrated the ability to run components of the standards-based Universal Application Network business processes. SeeBeyond is also collaborating with Siebel Systems to support the emerging industry standard, BPEL4WS, a language for business process execution. SeeBeyond's support for Universal Application Network is key in enabling organizations to move beyond the limitations of proprietary technologies to a more simplified and standardized solution for enterprise-class integration. As a result, organizations such as Infonet now have a framework on which to implement business processes that can reduce the need for customization, minimize complexity, and speed the time to deployment.

"Implementing efficient business processes based on best practices that span multiple applications is the number one challenge for organizations today," said Bharath Kadaba, Vice President, Integration Solutions for Siebel Systems. "SeeBeyond's support for Universal Application Network will help customers address the application integration challenge, while saving them time, money, and effort."

"As one of the first Universal Application Network partners, we are excited about reaching this important milestone and intend to aggressively support Universal Application Network," said Reed Henry, Senior Vice President of Services, Support, and Alliances for SeeBeyond. "As evidenced by more than 1,700 customer deployment worldwide, the SeeBeyond Business Integration Suite achieves unrivaled production throughput and scalability levels and delivers the capabilities to rapidly implement Siebel Systems' key business processes for Universal Application Network. The promise of the Real-Time Enterprise is now within reach -- customers can benefit from reduced customization, minimized complexity, and quicker deployment time while implementing enterprise business processes based on best practices."
