part of the Patents as defined herein.

<PAGE>
5.6 Proceedings
-----------
(a) If any infringement action, claims or proceedings of any kind are
threatened or commenced by a third party against either the Licensee
or against the Licensor because of the Licensee's exploitation of the
rights granted under this Agreement or its manufacture, distribution
and servicing of the Products or on the ground that the Products
infringe any registered design or patent monopoly right vested in such
third party, then the party so threatened or sued shall inform the
other forthwith in reasonable detail and the matter shall be referred
to leading patent counsel (well versed in the laws of the country in
which such matter will be determined) for the purpose of obtaining his
advice on whether a defence or a threatened action will have a
reasonable chance of a successful outcome and whether there are any
circumstances making it imprudent to defend or commence proceedings.
(b) If the Licensee only shall decide that such action, claim or
proceedings shall be defended, the Licensee shall bear the whole costs
thereof including any damages and costs awarded against it in favour
of such third party, and shall from time to time if requested notify
the Licensor of the progress thereof. At the request of the Licensor,
the Licensee may permit the Licensor to intervene or otherwise appear
in or in connection with any such action, claim or proceedings
personally or through Counsel selected by the Licensor, at the sole
expense of the Licensor provided that nothing contained herein shall
preclude the Licensor from defending such action, claim or proceedings
where the Licensee declines to do so.
5.7 Notices
-------
Any notice or other communication required or permitted to be given
hereunder shall be in writing and shall be deemed to have been duly given
if delivered by hand against receipt of the addressee or his duly
authorised agent or if sent by prepaid registered post addressed to the
party to whom it is addressed at the address set out for such party herein
or if sent by telefax to the party to whom such notice is to be given (or
such other address or telefax number as he may from time to time designate

hereof and any such notice shall be deemed to have been given if delivered

Agreement shall continue in force
<PAGE>
save that such provision shall be deemed to be excised herefrom with effect
from the date of such agreement or decision or such earlier date as the
parties may agree.
