a Master Hire Purchase Agreement dated 10th August 1999. Terms defined in the
Master Hire Purchase Agreement have the same meaning when used herein.

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

This License is incorporated by reference in the Master Hire Purchase
Agreement (see Clause 7 thereof).

      a) Whereas Licensee is a provider of health care and/or medical imaging
         services which at the time of execution hereof, holds all such

      b) Whereas Licensor places at the disposal of Licensee, either at or prior
         to the time of execution of the License, [       ] (the Equipment),
         and

      c) Whereas either (i) the Equipment comes fitted with OPERATING SOFTWARE
         and BASIC MAINTENANCE SOFTWARE, (together referred to as "LICENSED
         SOFTWARE") or (ii) the LICENSED SOFTWARE is delivered to Licensee
         subsequent to Acceptance of the Equipment, and

      d) Whereas Licensee desires to be granted a license to use said software,
         subject to the following terms and conditions.

2 - OWNERSHIP

Title to the LICENSED SOFTWARE (as well as to the ADVANCED PACKAGE described

ceases to hold any of the permits referred to in the first recall hereof, or
as soon as Licensee has failed to abide by any of its commitments hereunder,
to repossess all or any of the LICENSED SOFTWARE (and/or of the ADVANCED
PACKAGE described at paragraph 7 below), and any corresponding archival
copies.

3 - LICENSE

Licensor hereby grants to Licensee personally a limited, non-negotiable,
non-exclusive License to use the LICENSED SOFTWARE, (consisting of the

   Specific Terms of the Hire Purchase Agreement hereto ("the Site") and

   images;

-  3.2 The right to produce an archival copy of the OPERATING SOFTWARE, such
   right to be exercised solely through Licensee's own employees;

-  3.3 The right to load and run the BASIC MAINTENANCE SOFTWARE on the
   Equipment, subject to the latter remaining on the Site and being used
   solely for the purpose of maintaining the medical diagnostic equipment at
   the Site, each right to be exercised solely through Licensee's own
   employees;

-  3.4 The right to produce an archival copy of the BASIC MAINTENANCE
   SOFTWARE, such right to be exercised solely through Licensee's own
   employees;

-  3.5 Licensee is NOT granted any license with regard to any software other
   than the LICENSED SOFTWARE (that is, the OPERATING SOFTWARE and the BASIC
   MAINTENANCE SOFTWARE). Specifically, Licensee is not granted any license

8 - STORAGE OF MATERIALS NOT PURCHASED BY OR LICENSED TO LICENSEE

Licensee.  Some or all of such property might be in the Location from time to
time and some or all of which might be delivered to the Location with the
Equipment.  For convenience, Licensor personnel might store from time to time
such property in the Site for varying periods.  Licensee hereby consents to
the presence of a locked Licensor cabinet or box for such storage; to the use
of the Site for such storage without charge; and to Licensor's removal of any
or all of such property at anytime.

Licensee hereby agrees to use its best efforts to protect all of such property
from damage or loss and its best efforts to protect all of such property from
access or disclosure to or use by anyone other than Licensor personnel.  The
presence of such property in the Location shall not give Licensee any right or
title to the same or any license to use the same, but to the contrary, any
access, disclosure or use of any of such property to or by Licensee, its
employees or any person other than Licensor personnel is strictly prohibited,
and Licensor agrees that it will use its best efforts to prevent any access,
disclosure or use contrary to such prohibition.

9 - TERM

in force for as long as Licensee holds the permits referred to in the first
recital above, as it uses the Equipment on the Site, and as it fulfills its
commitments hereunder.  It will end upon termination of the hiring of Equipment
under the Master Hire Purchase Agreement howsoever arising.

<PAGE>

Licensor may terminate this license in the event of any breach by Licensee.
Upon termination or expiry hereof, License will return to Licensor, upon the
latter's first demand, the LICENSED SOFTWARE and corresponding archival
copies. Up until then, Licensee will continue to be bound by its commitments
hereunder notwithstanding the expiry of the License.

10 - CONSEQUENCES OF LICENSEE'S FAILURE TO COMPLY

Should Licensee fail to fulfill any of its commitments hereunder, Licensor
will be released from all and any of its commitments to Licensee. The
foregoing provision will not prejudice any other claims which Licensor may
have.

11 - COPYRIGHTS

PACKAGE are protected under the copyright legislation of the countries where
they have been developed, as well as under international copyright
conventions.
