   brochures  and  selling  programs,  and are  promoted in  LICENSEE's  general
   promotion programs, including LICENSEE's customer exhibits and presentations.

   (2) number of each  Coda / Vivace  Assessment  product  sold - (a) as a
       separate  unit or module,  and/or (b) as a  built-in  component  or

   method of reporting.
