GXS Joins Microsoft and Other Industry Leaders in the Interop Vendor Alliance

Sunbury, United Kingdom — November 14, 2006 — GXS™, a leading provider of business-to-business (B2B) e-commerce solutions, today announced that it has become a founding member of the Interop Vendor Alliance. This alliance, initiated by Microsoft, is intended to increase interoperability with Microsoft systems for customers and vendors of Microsoft technologies. Member companies will work collabouratively to ensure better interoperability of diverse back-office systems with Microsoft technologies.

GXS’ participation in this alliance follows the formation of a strategic alliance between Microsoft and GXS to market innovative solutions to speed and simplify integration between trading partners worldwide. A primary goal of the alliance between the two companies is to enable and improve integration between Microsoft-based systems and the supply chain. GXS and Microsoft recently completed the successful integration of Microsoft’s BizTalk Server 2006 and the GXS Trading Grid®. In addition, the two companies are working on a number of interoperability projects that will bring the GXS Trading Grid together with Microsoft platforms such as Microsoft SQL Server, Microsoft Office 2007, Microsoft Windows Vista and Microsoft Dynamics.

“The modern corporation is an amalgamation of diverse systems and technologies. The complexity of this model increases as companies outsource many of their IT and manufacturing functions to far-flung locations. This alliance seeks to reduce that complexity by ensuring interoperability with Microsoft technologies,” said Sam Rosenbalm, business development manager at Microsoft Corp. “GXS brings decades of experience in B2B processes and technologies to the Interop Vendor Alliance. GXS’ experience will be helpful in creating interoperable solutions on the Microsoft platform in areas such as global sourcing, supply chain visibility and B2B integration.”

Many midsize companies have invested in internal automation and productivity systems such as Enterprise Resource Planning (ERP) software and electronic data interchange (EDI). Unlike the biggest companies, midsize firms have not had the resources to ensure the interoperability of those systems with their Microsoft-based platforms and those of their trading partners. Connecting a company’s business systems internally and with those of its suppliers and customers will help midsize firms maximise the return on investment (ROI) of existing systems.

“Fundamentally, the Interop Vendor Alliance is about making the coordination and sharing of information within and between businesses easier. As it stands, even the most sophisticated IT professionals are challenged by the need to achieve interoperability between internal and external systems,” said Rowland Archer, chief technology officer of GXS. “Through its participation in the Interop Vendor Alliance, GXS intends to enable and simplify interoperability between business systems, with the end-goal of making B2B integration more straightforward and less time-consuming. GXS applauds the formation of the Interop Vendor Alliance and is pleased to have the opportunity to impact its direction.”

Founding members of the Interop Vendor Alliance include Sun Microsystems; AMD; BEA Systems, Inc; Business Objects; Carbon Project, Inc.; Centeris Corporation; Citrix; Computer Associates – Wily; GXS; JN Bridge LLC; KERNAL Networks; Levi, Ray & Shoup, Inc.; NEC Corporation of America; Network Appliance; Q4bis, Inc.; Quest Software; SIEMENS Networks LLC; Software AG; SugarCRM, Inc.; Symphony Services, Corp.; Xcalia and XenSource, Inc.
