Bob Segert Named CEO of GXS Effective January 1, 2008

Sunbury, United Kingdom — December 17, 2007 — GXS™, a leading provider of business-to-business (B2B) e-commerce solutions, today announced that business process outsourcing leader Bob Segert has been appointed its CEO effective January 1, 2008. Segert, presently leader of EDS’ Global Financial Products Industry, will succeed Gary Greenfield, who has led GXS for the last four years. Greenfield will remain as CEO through year end, and will continue to serve on the company’s board of directors.

Bob Segert brings more than 15 years of broad and diverse business leadership experience to GXS. As the leader of EDS’ Global Financial Products Industry, Segert oversaw mission-critical services, such as financial transaction processing, mortgage and consumer loan processing, life insurance business process outsourcing (BPO) and card processing. While at EDS, Segert also served as chief marketing officer, general manager of U.S. Financial Services and managing director of Corporate Strategy and Planning. He received a Masters in Business Administration from Harvard Business School and a Bachelors of Science degree in mechanical engineering from Purdue University.

“I am excited about the opportunity to lead GXS, and build on the industry-leading momentum that has been orchestrated by Gary Greenfield and Francisco Partners,” said Segert. “Over the last four years GXS has reinvented itself, defining and establishing a leadership position in the rapidly growing market for B2B outsourcing services. GXS’ ability to serve customers’ unique integration needs, worldwide, presents an important and differentiated position in an economy driven largely by two opposing forces: globalisation and faster speed-to-market. I look forward to building on the company’s strong relationships with customers, experienced global workforce, and proven technology base.”

“Bob is a superb choice to lead GXS into its next phase of growth,” said Greenfield. “His many years at EDS managing transaction-based systems, and building BPO services, will no doubt prove extraordinarily valuable in serving our customers rapidly evolving needs for real-time integration and non-stop service. Looking back, I am excited about the transformation GXS has accomplished. It was truly a great experience working with so many great customers and world-class, highly-committed employees.”
