Business Editors/High-Tech Writers

FAIRFAX, Va.--(BUSINESS WIRE)--July 22, 2003

On-Scene Photo Documentation Kit (OSPDK) Recently Implemented for

Coast Guard Incident Response and Shipboard Inspections

Xybernaut(R) Corporation (NASDAQ:XYBR) and Anteon International Corporation (NYSE: ANT) today announced a partnership agreement under which Xybernaut mobile/wearable computing technologies and the Anteon On-Scene Photographic Documentation Kit (OSPDK) platform have been combined into a single solution for various first responders and homeland security application.

In related news, the two companies confirmed that the U.S. Coast Guard has taken delivery of wearable OSPDK solutions for use during ship boarding operations and inspections of vessels for security and other purposes.

Under the teaming relationship, Anteon has joined Team Xybernaut(TM) as the systems integrator for OSPDK and other joint deployments. Both companies have been working together for more than four months to develop and deploy the integrated platform. The wearable OSPDK solution is initially being offered on the Xybernaut Mobile Assistant(R) V (MA(R) V) and Atigo(TM) wearable computers. The complete "kit" consists of a digital camera with built-in CF GPS unit, the Xybernaut MA V computer running image capture/transfer software, a wireless networking solution for transferring captured images, and web-based resources for viewing and managing the captured images.

The companies efforts are concentrating on military, intelligence and government applications, such as the U.S. Coast Guard, where field force technicians are expected to see increased accuracy and quality if mobile computing devices are deployed to support their day-to-day operations. The Coast Guard deployment is a good example of the potential for the joint system.

"The mobility and point-of-task computing power afforded by the joint Xybernaut-Anteon solution allows first responders increased flexibility and greater accessibility to knowledge at critical moments," said Joe Kampf, president and CEO, Anteon International Corporation. "In practice, an OSPDK operator can be dispatched to an incident scene where he/she can capture geo-referenced digital images using the digital camera. The camera then feeds these images to a software utility running on the wearable computer that transfers these images to an Internet FTP site residing on a remote commercial web server."

"Anteon and Xybernaut have proven experience with many first responder and homeland security communities," said Steven A. Newman, president of Xybernaut. "This joint Anteon-Xybernaut solution is already being accepted by our existing customers as a cost-effective platform for arming first responders with a more powerful and effective computing platform for critical incident response. Combined with Anteon's Common Situation Display System (CSDS), the wearable OSPDK turns operator-intensive tasks into more manageable activities AND provides decision makers with an efficient architecture for knowledge management and analysis."

Both companies are leaders in their respective markets -- Xybernaut in mobile/wearable computing, and Anteon in information technology, engineering and integration support. The companies have worked together to integrate the Xybernaut Mobile Assistant(R) V (MA(R) V) and Atigo(TM) mobile/wearable computers with the capabilities of the CSDS and OSPDK applications.
