   to the Speaker Verification software for use in PC and network
   security applications with authentication and/or signature functions.

   applications with authentication and/or signature functions.
   Both parties agree to work out the procedure under which such
   distribution shall take place.  A fee amounting to 30% of the
   revenues/license fees generated hereunder by LICENSOR, will be paid
   to LICENSEE.

   This exclusivity shall commence on January 1, 1999, and shall remain

   a)  does not enter into agreements with other speech software
     companies

     agreements;

   The failure to achieve any of the above cumulative conditions shall

   After two (2) years of the initial three (3) year period, LICENSOR
   and LICENSEE shall both agree on the performance criteria, based on
   but not limited to market share, which LICENSEE has to meet at the
   end of the third year.

   At the end of the initial three (3) year period (and each extension
   thereof), both parties shall evaluate the results and the commercial
   forecasts with a view to extend the exclusivity with one year
   periods.

   If both parties agree not to extend the exclusivity after any period
   hereabove mentioned, both parties agree that the agreement shall
   continue on an non-exclusive basis for the term of the Agreement.

   LICENSEE acknowledges that the above exclusivity shall not apply to
   existing customer base of LICENSOR, as well as to chip and board
   manufacturers.
