Shares and Warrant Price shall be subject to the following adjustments:

                  (a)      In the event that, while the Warrant has not been

the holder shall be preserved, by adjusting, in accordance with French Law, the
number of shares to be issued upon the exercise of Warrant so as to entitle the
holder thereof to subscribe such number of shares that have the same aggregate
value immediately following such event as the shares that could have been
subscribed for immediately prior to such event.

                  (b)      In the event of share capital reduction motivated by
losses, the rights of the holder in respect of the number of shares to subscribe
and purchase upon exercise of this Warrant will be reduced accordingly, as if
the holder had been shareholder as from the date of issue of the Warrant, and as
if the Warrant had been fully vested as of that date.

5.                Non transferability of Warrant.

                  (a)      Except as provided in sub-section (b) below, this
Warrant and all rights hereunder may not be sold, pledged, assigned,
hypothecated, transferred, or disposed of in any manner other than by will or
laws of descent or distribution and may be exercised, during the lifetime of the
holder, only by the holder.

                  (b)      The transfer of this Warrant to the holder's

however that the transferee agrees to be bound by and comply with the provisions
of this Warrant, and signs a consent in the form attached hereto. << Immediate
Family >> as used herein shall mean the spouse, a direct descendant or
ascendant, a brother or a sister of Jean-Francois Heitz.

or any other means and does not constitute evidence of ownership. If and when
allowed, assignment of all or part of this Warrant may only be completed by
notifying the form of assignment attached hereto, duly completed and signed by
the holder.

the Warrant will be notified and given the same information as if he were a
shareholder in order to exercise, if he wishes so, his subscription rights.
Moreover, had he not acquired his full rights, the Board of Directors may, in
its sole discretion and as an exception to section 2 hereof, decide to increase
