eBuilder Enables Open, Scalable, Java(R)-Based Business-to-Business

and Business-to-Consumer eCommerce Solutions Using IBM WebSphere(TM)

and Evergreen ECential(TM)3.0

Caldera Systems Inc. (Nasdaq:CALD), the "Linux for eBusiness" leader, today announced the availability of OpenLinux eBuilder, a 100% open standards eBusiness solution that includes IBM's WebSphere application server and Evergreen's ECential 3.0 Open Commerce Framework.

OpenLinux eBuilder enables existing business processes to be re-engineered for the Internet across all supported hardware platforms and database systems. This greatly reduces the cost of eCommerce solutions implementation for businesses deploying new and legacy systems, while increasing margins for VARs, systems integrators and electronic Service Providers (eSPs). eBuilder builds on the foundation of OpenLinux eServer, a thin, component-based operating system that makes Linux servers easy to install, configure and manage remotely through Webmin.

Included in OpenLinux eBuilder is Evergreen's ECential 3.0, which delivers robust, open standards-based (Java, XML) distributed eCommerce services and components that enable high performance solutions for enterprise or Application Service Provider (ASP) eBusiness sites.

IBM's WebSphere delivers the industry's leading open standard application server for secure (SSL) Web server applications, supporting both 56 and 128-bit encryption. Together, OpenLinux, WebSphere and ECential deliver the most powerful open standards platform for building the next generation of eBusiness solutions.

OpenLinux eBuilder strongly positions Caldera as the leader in open standards-based eCommerce services and components that ideally leverage the OpenLinux platform for distributed, manageable, and low cost/high performance eBusiness solutions.

By providing open standards-based eCommerce building blocks and infrastructure to systems integrators, developers and consultants, OpenLinux eBuilder becomes an ideal platform to help enable customized and integrated business-to-business (B2B) and business-to-consumer (B2C) solutions.
