                  to use any of the IPR nor has Mr.  Ross  received  any  notice
                  that any of the IPR conflicts or will conflict with any of the
                  asserted rights of others.

         6.5      Mr.  Ross  will use his best  efforts  to  prevent  any of his

                           under the  Securities Act or unless an exemption from
