    PRICE OF EXERCISE OF OPTIONS9.1
    
    Share purchase priceThe purchase price of each Share that may be acquired by the exercise of an Option by a
Participant shall be determined by the Board within the limits set in the Shareholders
Authorisation and the provisions of the applicable laws and regulations.The determination of such price is subject to the following rules:
 
    
    The Share purchase price shall be neither less than 85% of the average closing price
of the Shares on the French Nouveau Marchéover the 20 trading days immediately prior
to the Grant Date of the Options, nor less than 100% of the maximum purchase price of
the Shares held by the Company under Articles L. 225-208 and/or L. 225-209 of the
French Commercial Code.
    
    If the shares should cease to be listed on a regulated stock market, the Share
purchase price shall be determined by the Board in accordance with the provisions of
Article L. 225-177, paragraph 4, of the French Commercial Code. In any case the price
fixed by the Board may not be less than 80% of the purchase price of the shares that
would be held by the Company under Articles L. 225-208 of the French Commercial Code.
 The Share purchase price, determined as above, may not be modified, subject to section 12.1
below.9.2
    
    Payment of the purchase price of the SharesThe terms of payment of the purchase price of the Shares shall be determined by the Board at
the Grant Date of the Options.Unless decided otherwise by the Board, the purchase price of the Shares shall be entirely
paid for upon exercise of the Options, such payment to take place by cheque, bank wire
transfer or set off with liquidated, certain and due debts of the Company to the
Participant.All payments related to the exercise of Options between the Company and a Participant shall
be in EURO.9.3
    
    Exercise of the Options and Tax & other liabilitiesWithin thirty (30) days after Options have been exercised by a Participant, the Board, on
behalf of the Company, shall procure the transfer to such Participant of the corresponding
number of Shares, provided that:
 (i)
    
    the Board considers that the transfer of Shares would be lawful in the
jurisdiction in question; and(ii)
    
    in the event that the Company or any Affiliated Company or any other company
(the Taxed Company) is required to (or may suffer a disadvantage if it were not to)
pay for any tax, charge or social contributions for which the Participant in question
is liable by virtue of the exercise of the Option (together, the Liability ), the
Participant has either:
 
    
    made a payment to the Taxed Company of an amount equal to the Liability; or




---



##### 




    
    entered into an arrangement acceptable to the Taxed Company in order to
secure the payment of the Liability (whether by authorising the sale of some or
all of the Shares on its behalf and the withdrawal of the Liability from the
proceeds of sale by the Taxed Company or otherwise).
 9.4
    
    IndemnityIf, as a result of the grant of Options, exercise of Options or sale of the Shares, the
Company or any Affiliated Company is liable for taxes, employee related social charges or
other financial charges, in jurisdictions where such possibility is permitted, the
Participant shall fully indemnify the Company or any Affiliated Company in respect of all
such amounts payable by the Company or any Affiliated Company to the fullest extent
permissible by the legislation applicable to the Participant, for example where such
applicable legislation limits the imposition of such charges upon the Participant.10.
    
    EXERCISE OF OPTIONS10.1
    
    Exercise procedure; Rights of Participants who become shareholdersOptions granted under the Plan shall be exercised in accordance with the terms of the Plan
and at such dates and under such conditions as determined by the Board and set forth in the
Notice of Grant or, in the event of no specific indication in the Notice of Grant, as
determined in the Local Plan.An Option shall be deemed exercised when the Company (or a company agent) receives: (i)
written notice of exercise together with a share purchase form duly executed by the person
entitled to exercise the Option, and (ii) full payment of the underlying Share purchase
price. Shares acquired by exercise of Options shall be transferred to a nominative account
registered in the name of the Participant or, if requested by the latter, in the name of the
Participant and his or her spouse, provided such spouse first executes all undertakings and
agreements the execution of which constitute condition precedent to the grant of the Options
or purchase of the relevant Shares.Upon exercise of the Options, the Shares transferred to the Participant shall be assimilated
with all other Shares of the Company, which fall within the same class and shall qualify for
dividends for the fiscal year during the course of which the Options have been exercised.Each grant of Options shall decrease the number of Shares, which are thereafter available
for the purposes of the Plan, by the number of Shares that may be acquired by exercise of
the Options.10.2
    
    Exercise datesAt the Grant Date, the Board shall set the period during which the Options may be exercised
and shall determine the conditions which must be satisfied before the Options may be
exercised. For instance, the Board may provide that the Options may not be exercised until
the completion of a minimum period of employment.The Options can only become exercisable if the participant has acknowledged receipt of the
grant and has returned the completed form provided by the Company prior to the expiration of
the three-month deadline beginning at the date of the Notice of Grant.The rules specifying the Exercise Dates of the Options are set forth in the applicable
Schedule to the Core Plan (French Plan, US Plan, or International Plan) or as the case may
be, in the Notice of Grant.

employment contract or officeUpon loss by a Participant of his Continuous Status as an Eligible Person, other than upon
the Participants Disability or death, the Participant may exercise his or her Options only
during such time period as specified hereinafter and such exercise may concern only such
number of Options that he/she was entitled to exercise (pursuant, in particular, to section
10.2 above) as of the date of such loss.Unless provided otherwise in the relevant Notice of Grant, the Options may be exercised
during a period of one (1) calendar month following the loss by the Participant of his

date of the Participants resignation, without taking into account any advance notice period
nor the effective dates of such termination or resignation.The date of termination of office shall be the date of the shareholders meeting or Board

date of first delivery to the relevant Participant of his/her notice of termination or the
date upon which such notice shall be hand delivered to such Participant. The date of
resignation from employment shall be either the date of dispatch by the relevant Participant
to the Company (or any Affiliated Company thereof) of his/her notice of resignation or the
date upon which such notice shall be hand delivered by such Participant to the person he/she
reports to within the Company (or any Affiliated Company thereof). In the absence of such a
written resignation, the resignation date shall be the date at which the Participant shall
be deemed to have resigned under applicable labour laws.The date of resignation from office shall be, as the case may be, the date of dispatch or

Affiliated Company thereof) or the date of the shareholders meeting or Board meeting in the
course of which the relevant Participant shall have resigned.Should the relevant Participant not exercise all the Options that he/she was entitled to
pursuant to the above within the time period determined as provided for above, the relevant
Shares not acquired by the exercise of such Options become available again to be subject to
new Options to be granted to other Eligible Persons under the Plan.10.4
    
    Disability of a ParticipantShould a Participant lose his Continuous Status as an Eligible Person as a result of
Disability, he/she may exercise his/her Option at any time within three (3) calendar months
from the date of such loss, but such exercise may concern only such number of Options that
such Participant was entitled to exercise as of the date of such loss.Should the relevant Participant not exercise the Options he/she was entitled to pursuant to
the above within the time period determined as provided for above, the relevant Shares not
acquired by the exercise of such Options become available again to be subject to new Options
to be granted to other Eligible Persons under the Plan.10.5

may be exercised at any time within six (6) calendar months following the date of death, by

Participants heirs but such exercise may only bear on the number of Options that such
Participant was entitled to exercise as of the date of his death.Should the relevant Options not be exercised within the time period determined as provided
for above, the relevant Shares not acquired by the exercise of such Options become available
again to be subject to new Options to be granted to other Eligible Persons under the Plan.10.6

out any financial operation, the Board may among others impose a suspension period not
