Business Editors/High-Tech Writers

LONDON & REDWOOD SHORES, Calif.--(BUSINESS WIRE)--Dec. 16, 2002

SeeBeyond (Nasdaq:SBYN), the leading global provider of eBusiness and Application Integration (eAI) solutions, announced today that Butler Group, Europe's leading independent IT analyst firm, has ranked SeeBeyond as the number one integration software vendor in the Butler Group's EAI and Web Services report -- "Cutting the cost of Enterprise Integration".

With integration increasingly becoming a priority in global organizations, Butler Group has published this report assessing the various offerings from leading eAI vendors, including detailed technology audits on products from BEA, IBM, Microsoft, SeeBeyond, TIBCO and webMethods. Butler Group ranked the SeeBeyond(TM) Business Integration Suite number one due to its comprehensive and straightforward integration capabilities, including significant support for integration utilizing Web services, and its strong focus on delivering return on investment benefits to the customer.

Commenting on the evaluation of SeeBeyond's integration software, Theresa Jones, author of Butler Group's EAI and Web Services report, said, "SeeBeyond impressed Butler Group, especially because of its delivery on the vision of high level business process management and monitoring, combined with the flexibility of its integration capabilities."

According to Butler Group, the Enterprise Application Integration market is facing much consolidation, although strong opportunities still exist for growth as the tools available to deliver integration solutions become simpler and more cost effective. "The importance of the user interface for integration, enabling business analysts to deliver rapid solutions to their organizations, should not be underestimated. Pure-play integration vendors, such as SeeBeyond, are currently providing much of the innovation in the market, including some of the newer integration elements such as business process management and the all-important monitoring of the performance for those processes," added Jones.

Dr. Ian Howells, vice president of Marketing in EMEA for SeeBeyond, added, "eAI is more important than ever, as continued economic and the consequent board room pressures demand CIOs and IT directors to consolidate and drive return on investment from existing, incompatible systems. In a world where the average enterprise must integrate at least 50 applications(1), organizations need to know which integration vendor they can trust to offer the best solution -- particularly as integration remains the number one priority for CIOs in terms of IT spend(2)."

"Butler Group's recent ranking of integration companies, which places SeeBeyond ahead of its competitors, recognizes our leadership in providing comprehensive solutions that focus on delivering return on investment," said Jim Demetriades, founder, president and CEO of SeeBeyond. "SeeBeyond remains committed to delivering innovative enterprise-class solutions to our customer base, as well as expanded investment in strategic product development."
