Item 4.   CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT

     Effective December 5, 2002, Infodata Systems Inc. (the "Company") dismissed
its prior certifying accountants, PricewaterhouseCoopers LLP ("PWC") and
retained as its new certifying accountants, Grant Thornton LLP. The decision to
change accountants was approved by the Company's Board of Directors.

     During the last two fiscal years and the subsequent interim period to the
date hereof, there were no disagreements between the Company and PWC on any
matters of accounting principles or practices, financial statement disclosure,
or auditing scope or procedure, which disagreements, if not resolved to the
satisfaction of PWC, would have caused it to make a reference to the subject
matter of the disagreements in connection with its reports.

     The reports of PWC on the Company's financial statements for the past two
fiscal years did not contain an adverse opinion or a disclaimer of opinion and
were not qualified or modified as to uncertainty, audit scope or accounting
principles with the exception of an explanatory paragraph, as disclosed in those
financial statements, relating to the Company's ability to continue as a going
concern.

     During the last two fiscal years and through the subsequent interim period
to the date hereof, the Company did not consult Grant Thornton LLP regarding any
of the matters or events set forth in Item 304(a)(2)(i) and (ii) of Regulation
S-B.
