Xybernaut(R) Corporation (NASDAQ:XYBR) has recently attracted attention from several news outlets primarily related to the Company's deployment at the Robins Air Force Base (AFB) in support of the 116th Air Control Wing.

WHEN/WHERE: Selected samples of recent coverage include the following

    --  April 21, 2004, Air Force Link News -- Tim Beckham, "Wearable
        Computers Move to the Flightline"
        http://www.af.mil/news/story.asp?storyID=123007534

            Excerpts: The small personal computers can be worn either
            on the chest or hip and are being tested as a possible
            replacement for printed manuals currently used.

            "With (the) integrated electronic technical manual, the
            flightline mechanic will have access to a wealth of
            information needed to perform (his or her) duties," said
            Tech. Sgt. Matt Jones, the electronic manual's project
            manager.

            "Having these tools at the maintainers' fingertips is
            actually a virtual office on the flightline," said Col.
            Terry Kinney, 116th MXG commander. "It will have much of
            the same desktop software that we currently use, like
            e-mail capabilities and the capabilities to identify,
            order, ship and pay for parts directly from the
            flightline."

    --  May 17, 2004, The Macon Telegraph, Gen Rector, "Wearable
        Computers Opening New World for Aircraft Mechanics."
        http://www.macontelegraph.com

            Excerpts: "Aircraft mechanics in the 116th Air Control
            Wing don't have to go by the office these days. They carry
            it with them - hung around their necks or strapped to
            their waist.

            Maintainers from the Joint STARS unit at Robins Air Force
            Base have been testing "wearable" wireless computers over
            the past several months, and they're finding that the
            24-ounce devices open a new world of information access
            and mobility.

            Xybernaut, a Fairfax, Va., company, developed the hardware
            and Northrop Grumman added Web-based software known as
            Phoenix. The resulting package ties the flightline
            mechanic to a vast array of information for servicing the
            Boeing 707 airframe used by the ground surveillance wing.

            "The mechanics can access virtually anything," said Tech.
            Sgt. Matt Jones, software manager for the testing project.
            "They have immediate access to work cards, checklists,
            illustrated parts breakdowns, wiring diagrams,
            trouble-shooting procedures. They can also access existing
            or previous write-ups or problems on the aircraft. We have
            101 units right now and we're getting 50 more. Every
            maintenance person will have access to one. That means we
            can deploy to any hot spot in the world, set up the
            wireless network and get information real-time."
