REGISTRATION/ORDERING INFORMATION

      German users see GERMANY.TXT.

      A SIO/VSIO/VX00 registration licenses you to use the product on a
      regular basis.  Individual users need register only one copy of
      SIO/VSIO/VX00 for personal use;  registration includes licensed
      use of all upgrades to the major version number registered.  When
      the major version number changes, say from 1.55 to 2.00, you must
      re-register (pay up again).  Upgrades are NOT automatically sent
      to registered users.  See LICENSE.TXT for additional information.

      The registration fee covers only the use of the program.

      Please use the registration form (below) to send in your
      registration fee. 

      For support information, see the Users Manual (SIOUSER.TXT).

                       Corporate and Quantity Purchases

      All corporate, business, government or other commercial users of
      SIO/VSIO/VX00 must be registered.  We offer quantity discounts
      starting at the eleventh copy.  Corporate or site licensing is
      also available.

      Licensing agreements allow duplication and distribution of
      specific numbers of copies within the licensed institution. 
      Duplication of multiple copies is not allowed except through
      execution of a licensing agreement.

      The quantity discounts are as follows: 
       
           00 - 10 copies:     no discount 
           11 - 25 copies:     15% discount

           51 - 100 copies:    25% discount 
           101+ copies:        30% discount 
       
      ALL PRICES AND DISCOUNTS ARE SUBJECT TO CHANGE WITHOUT NOTICE. 
      Discounts are not cumulative; they apply to single orders of like
      products only. Unit prices are the same as for individual users.  

      YOU MUST REGISTER SIO/VSIO/VX00 TO USE THEM WITHIN YOUR
      ORGANIZATION.
