XML APPLIANCE LEADER SARVEGA NAMES CHRIS DARBY, FORMER CEO OF PREMIER SECURITY CONSULTANCY @STAKE, PRESIDENT AND CEO
Increasing Demand for Sarvega's XPE Appliances Drives Addition to Management Team

Chicago, IL – July 21, 2003 – Sarvega™ , Inc., the leading provider of XML appliances, today announced that industry veteran Christopher Darby has joined the company as president and chief executive officer. Darby brings extensive experience heading innovative market leaders such as the Internet security consulting company @stake and, prior to that, Interpath (now USinternetworking, Inc), an application service provider (ASP). In addition to his new operating responsibilities, Darby also joined Sarvega’s Board of Directors. Sunil Gaitonde PhD, co-founder and former president and CEO, will assume the position of chief technology officer (CTO).

“Sarvega has achieved significant milestones under Sunil’s leadership, including securing major Global 1000 customers and delivering the most comprehensive platform for handling the complexities of XML/Web Services processing,” said Steve Bowsher, general partner with InterWest Partners, one of Sarvega’s investors, and a member of Sarvega’s Board of Directors. “InterWest is pleased that Chris is joining the team to lead Sarvega from successful start-up to dominant player in the growing industry.”

Darby arrives at a time when Sarvega’s customer base and position in the XML/Web Services market are expanding, which led to Sarvega recently closing $10 million of Series B funding. The total capital Sarvega has raised is over $20 million, the largest amount invested in any XML appliance vendor.

Before coming to Sarvega, Darby served as chairman and CEO of @stake. Darby is widely credited with building @stake into the world’s largest independent Internet security consulting company. Prior to joining @stake, Darby served as president and CEO of Interpath. Under his guidance, Interpath emerged from a division of Carolina Power and Light (CP&L) to become one of the foremost ASPs. Interpath is now part of USinternetworking. Darby also held several executive positions at Digital Equipment Corporation (now Hewlett-Packard) with responsibility for telecom industry initiatives, corporate strategy, and alliances. Darby began his career at Northern Telecom (now Nortel Networks) and Bell Northern Research (BNR), the research and development arm of Nortel Networks.

“Sarvega has been instrumental in developing the XML appliance market and is now entering a significant growth phase. As the use of XML for critical applications such as Web services continues to grow, the demand for Sarvega’s XPE family of XML appliances is increasing. I am very pleased to join the company at this dynamic time and expand its market and technology leadership position,” said Darby.

Deployed in such Global 1000 organizations as 3Com and Fujitsu as well as healthcare institutions such as Chicago’s Mt. Sinai Hospital Systems, Sarvega’s XPE™ appliances have saved Sarvega’s customers millions of dollars while delivering order-of-magnitude performance improvements in customer applications.

Sarvega’s XPE appliances deliver these impressive economic and architectural benefits due to the industry-first approach of transparently decoupling complex XML processing tasks from the application infrastructure and offloading them to the network infrastructure. The XPE family is built on Sarvega’s patent-pending core technology, XML EventStream™ Operating System (XESOS™). XESOS, which addresses all facets of XML processing from XSL transformation to XML/Web services security, is the most flexible and comprehensive core technology platform in the market.

"I am very pleased that Sarvega’s market leadership position and unmatched customer traction have enabled us to attract a new member of the team with the impressive credentials andexperience that Chris brings with him. I look forward to working with him as we take Sarvega to new heights,” said Gaitonde.
