                    INFODATA SYSTEMS INC. EXPECTS TO RECEIVE
                       PARTIAL STOP-WORK ORDER ON CONTRACT

Fairfax, VA March 1, 2002 - Infodata Systems Inc. (OTCBB:INFD) announced today
that it expects to receive a Stop-Work Order from the U.S. Government Agency
overseeing its contract to develop and implement a complex document production
management system. It is anticipated that this order will halt work on a
significant portion of the contract until the Government completes its review
and makes a final determination as to its requirement for the contracted effort.
This review may take up to 90 days. The contract represented approximately 40%
of the Company's revenues during calendar 2001.

Steve Samowich, President of the Company, stated, "We are obviously disappointed
with the Government's action. This does not reflect on Infodata's work, but is
rather the Government reassessing its requirements."

Infodata designs, develops and delivers solutions that enable enterprises to
share, maintain and retrieve electronic documents, and provides consulting and
systems integration services and products in the area of knowledge management to
corporate and government organizations.
