Dear Andre:

This letter will  constitute the mutual  agreement  between you and  QueryObject
Systems Corporation ("QueryObject Systems") on the terms of your separation from
employment with QueryObject  Systems.  You and QueryObject Systems agree that we
desire to minimize the commitment of time, expense and resources involved in the
termination of your employment by entering into this Separation  Agreement,  and
accordingly, have agreed as follows:

1.       Your employment terminated effective April 30, 1999.

2.       You have been paid your earned  salary  through the  effective  date of
         your termination.

3.       You will  continue to receive the  previously  agreed upon  payment for
         medical  insurance of your own  choosing and will receive  company-paid
         dental  insurance  through April 30, 2004. If you become  covered under
         any  medical  or dental  insurance  plan(s)  provided  by a  subsequent
         employer,  then  the  cost  of  coverage  required  to be  provided  by
         QueryObject Systems shall be reduced by the amount of coverage provided
         by the  subsequent  employer's  plan(s)  for so long  as such  coverage
         continues. You will be responsible for notifying QueryObject Systems of
         subsequent insurance coverage.

4.       You will return to QueryObject  Systems Corporation any information you
         have about QueryObject  Systems practices,  procedures,  trade secrets,
         customer lists,  or product  marketing.  You may keep the laptop,  port
         replicator, and Canon Multipass already in your possession, however, we
         will need you to return the pager.  The cellular  telephone number will
         be transferred to your personal billing,  and all other telephones will
         be shut off per your instructions.

5.       QueryObject  Systems  will  provide you with the  severance  payment of
