           PERSONAL APT DISCOUNT POLICY FOR INSTRUCTOR/STUDENT USE


          Reflecting the desire of  Digital Manufacturing Systems to
          support  and  promote  the  expansion  of  NC  programming
          knowledge,  we  are  pleased  to  announce  the  following
          discount policy for Instructors and Students.

          When  a  single  order  for  five  (5)  or  more copies of
          PERSONAL APT are ordered for Instructor/Student use, by an
          accepted school or training program, registration packages
          will be provided for the Instructor/Student Discount price
          of $15 per package.

          Following  are   the  terms   of  qualification   for  the
          Instructor/Student Discount:

              1. The order must be received on official school forms
                 (PO's, letterhead, etc.) and signed by a school
                 official (Instructor, Administrator, etc.).

              2. A PERSONAL APT Registration form must be completed
                 for each Instructor/Student.

          Digital   Manufacturing   Systems   further   grants   the
          Instructor or Student the  right to install the officially
          registered copy  of PERSONAL  APT on  a classroom computer
          for his/her personal use during the duration of the class.

          In  addition  to   the  above,  under   this  policy,  the
          registered  Instructor/Student  user  will  have  the same
          rights and privileges  as any registered  user of PERSONAL
          APT.

          Any questions regarding this policy should be directed to:
