CONSULTING AGREEMENT WITH CLARIA CORPORATION

      On June 14, 2000,  Infodata Systems Inc. (the "Company")  entered into a
Consulting  Agreement with CLARIA  Corporation,  a company located in Mountain
View,  California,  ("CLARIA")  pursuant  to which the  Company  will  provide
consulting  services  to  CLARIA,  including   business-to-business   Internet
solutions  services and the design and  development  of an e-commerce  website
system. In addition to the Company's standard  consulting fees, the Consulting
Agreement  provides  for the grant to the  Company  of  warrants  to  purchase
145,000  shares of  CLARIA's  common  stock.  Afforded  to the  Company at the

equal to  CLARIA's  market  value as of the  closing  of its Series B round of
financing,  but in no event will the exercise  price be greater than $1.50 per
share. The warrants will expire four years from the date of grant.
