              Infodata Announces Profitable Fourth Quarter and 2002
    Company Continues Earnings Trend With Third Consecutive Quarterly Profit

Fairfax, VA., April 2 - Infodata Systems Inc. (OTCBB:INFD), a leading content
management solutions company, today announced financial results for its fourth
quarter and the year ended December 31, 2002. The Company reported net income
for the year of $688,000, or $.14 per share, compared to a loss of $150,000, or
$.03 per share, for the prior year. For the quarter ended December 31, 2002, net
income was $284,000, or $.06 per share, compared to net income of $10,000, or
$0.00 per share, for the quarter ended December 31, 2001.

Revenue for the year ended December 31, 2002 was $9,802,000, a decrease of
$5,723,000, or 36.9%, from revenue of $15,525,000 for the prior year. For the
quarter ended December 31, 2002, revenue was $2,158,000, a decrease of
$1,583,000, or 42.3%, when compared to $3,741,000 for the year-earlier quarter.
The decline in fourth quarter and 2002 revenue was the combined result of the
termination for convenience of the Company's largest government contract, which
was partially offset by revenue from a new contract with the same customer;
lower revenue from the sale of third party products; and the completion of two
large commercial contracts in 2001.

Operating profit was $711,000 for the year ended December 31, 2002, compared to
an operating loss of $1,182,000 for the year earlier period. For the quarter
ended December 31, 2002, operating profit was $288,000, an increase of $240,000
when compared to an operating profit of $48,000 for the quarter ended December
31, 2001.

For the year ended December 31, 2002, gross margin was 37.8%, an increase of
16.3% when compared to 21.5% for the year ended December 31, 2001. Gross profit
increased by $368,000 for the year ended December 31, 2002. For the quarter
ended December 31, 2002, gross profit was nominally lower when compared to the
quarter ended December 31, 2001. The 2002 increase in gross profit and gross
margin, despite the decline in revenue, was primarily the result of reduced
revenue from the sale of low-margin third party products. Revenue from the sale
of third party products was $528,000 in 2002, compared to $1,756,000 in 2001, a
decrease of $1,228,000, or 69.9%.

Research and development (R&D) expenses increased to $731,000 for the year ended
December 31, 2002, an increase of $241,000 over the prior year. For the quarter
ended December 31, 2002, R&D expenses were $241,000, an increase of $184,000
when compared to the quarter ended December 31, 2001. The increase in R&D
reflects the Company's decision to further invest in the development and
enhancement of new and existing proprietary products.

              Infodata Announces Profitable Fourth Quarter and 2002
    Company Continues Earnings Trend With Third Consecutive Quarterly Profit

Selling, general and administrative (SG&A) expenses were $2,267,000 for the year
ended December 31, 2002, a decrease of $1,769,000, or 43.8%, when compared to
$4,036,000 for 2001. For the quarter ended December 31, 2002, SG&A expenses were
$505,000, a decrease of $431,000, or 46.0%, when compared to the year-earlier
quarter.

For the year ended December 31, 2002, cash and short-term investments increased
$396,000, or 39.5%, and working capital increased $822,000, or 110.9%. These
increases were primarily the result of the Company's return to sustained
profitability beginning in the second quarter combined with the reduction and
control of operating expenses. At December 31, 2002, the Company had $1,398,000
in cash and short-term investments, working capital of $1,563,000, and an
outstanding balance of $55,000 on its credit facility. The Company reported cash
and equivalents of $1,002,000, working capital of $741,000, and an outstanding
balance of $616,000 on its line of credit as of December 31, 2001.

Edwin Miller, president and chief executive officer of Infodata, said, "The
Company has done a good job of eliminating unprofitable activities, managing its
costs and improving its margins in 2002. This year we are laying the groundwork
for growing the Company while delivering value to our loyal customers and
shareholders. With increased working capital and the new additions to the
management team in place, we are focused on expanding the Company's content
management solutions offerings. Specifically, we are expanding sales, marketing,
and product development initiatives to build for profitable revenue growth.
Although this investment in infrastructure in 2003 will lower our profit,
especially in the first three quarters of 2003, it is a vital step to remain
competitive, and is critical to enable future profitable revenue growth in 2004
and beyond."
