7.   In order to implement the agreement provided under the Share Purchase
Agreement, the parties hereto agree, in the terms described below, upon a

Assignor and the Assignee having close respective fields of activity.  This
Partial Trademark Assignment and Trademark Coexistence Agreement will be
interpreted and construed in light of the terms of the Share Purchase Agreement.

               orthopaedic devices ;

     (ii)      any products or services competing in any manner whatsoever with

               the existing inventory as of the date hereof.

                                      -6-

               In the event that the Trademark would be declared void or lost by

to any compensation of any kind whatsoever.

               -------------
