The share capital is set at the sum of EIGHT
MILLION EIGHT HUNDRED SEVENTEEN THOUSAND SEVEN HUNDRED SIXTY-FIVE EUROS AND SEVENTY CENTS (€8,817,765.70), divided into EIGHTY-EIGHT
MILLION ONE HUNDRED SEVENTY-SEVEN THOUSAND SIX HUNDRED FIFTY-SEVEN (88,177,657) shares with a nominal value of €0.10 each,
all fully paid-up and all of the same class.”



Article 7 - Increasing, reducing and
redeeming the share capital



The share capital may be increased, reduced
or redeemed in accordance with the provisions of the legislation in force.



The general meeting may, among other things,
decide to reduce the share capital, either by reducing the nominal value of the shares, or by reducing the number of shares.



Article 8 - Form of the shares



The company's shares are registered or bearer
shares. The existence of shares results from their registration in the name of the holder(s) in accounts maintained for that purpose
by an authorized intermediary duly empowered by the company, under the conditions and in accordance with the procedures provided
for by the law.



At the request of any shareholder, a shareholding
certificate will be issued to them via the authorized intermediary.



Article 9 - Share transfers



1.All share transfers must take
place in accordance with the provisions of the law. All expenses resulting from share transfers will be payable by the transferee.

stipulated by the legislation and regulations in force.



2. The company's shares are freely
transferable.



Article 10 - The rights and obligations
attached to shares



1. The rights and obligations attached
to each share will remain attached to it regardless of who owns it, and the transfer of a share will include all dividends that
are due for payment but have not yet been paid, and all future dividends and also, where applicable, the corresponding share of
reserve funds and provisions.



5





The ownership of a share entails, ipso
facto, approval by the holder of these Articles of Association and an obligation to be bound by decisions taken by shareholders'
general meetings.



Except in cases where this conflicts with
the provisions of the law, each shareholder has as many voting rights and will have as many votes at general meetings as the number
of shares that they hold in respect of which all sums due for payment have been paid. At equal nominal value, each share entitles
the holder to one vote.



Each share entitles the holder, in respect
of the company's profits and assets and the liquidation profit, to a portion of these that is proportional to the number and nominal
value of the shares in existence.



Whenever it is necessary to own several
shares or securities in order to exercise any right whatsoever, the shareholders or holders of securities will be personally responsible
for grouping together the necessary number of shares or securities.



2.Any natural person or legal entity,
acting either alone or in concert, that comes to hold a number of shares representing a proportion of the share capital or voting
rights that is equal to or greater than 1% of the share capital or voting rights, or any multiple of this percentage, including
any in excess of the declaration thresholds provided for by the legislation and regulations in force, must inform the company of
the total number of shares and voting rights that they own, and also inform it of the number of securities giving future access
to the capital, and the number of any voting rights that may be attached to these, by means of a letter sent by recorded delivery
with return receipt, within a timeframe of ten (10) days as from the time crossing the threshold in question.



This obligation to inform the company also
applies whenever a shareholder's holding in the share capital or the voting rights falls below one of the thresholds mentioned
in the preceding paragraph.



If not declared in accordance with the provisions
of the Articles of Association, shares exceeding the portion which should have been declared will be deprived of their voting right
at shareholders' meetings, in accordance with the provisions of the Commercial Code, if, at a meeting, the failure to have made
a declaration is noted and one or more shareholders that together hold at least 5% of the share capital request this at this meeting.



Article 11 - Paying for shares



Sums to be paid in payment of cash shares
subscribed for on the score of a capital increase will be payable in accordance with the terms decided on by the extraordinary
general meeting concerned.



On the occasion of a capital increase, the
initial payment cannot be less than one-quarter of the nominal value of the shares plus, where applicable, the whole of the share
premium.



6





Calls for payment of the balance shall be
made by the Board of Directors in one or more stages within a timeframe of five (5) years as from the date of accomplishment of
the capital increase.



Sums remaining due in respect of shares
to be paid for in cash shall be the subject of calls for payment issued by the Board of Directors, which shall determine the dates
and amounts of calls for funds.



Shareholders that do not pay sums due in
respect of shares held by them by the due payment date will ipso jure owe the company interest for late payment, calculated
daily as from the due payment date and charged at the official interest rate applicable in commercial matters increased by three
percentage points, without prejudice to the compulsory enforcement measures provided for by the law.

representative's term of office shall be the same as that of the legal entity that they are representing. If a legal entity revokes
its permanent representative's appointment, it must replace them immediately. The same provisions will apply in the case of the
death or resignation of the permanent representative.

office at any time. Any conflicting provision will be deemed to have not been written.

the Chairman of the Board shall always be eligible for reappointment.



The Board of Directors shall appoint from
among its members a Board member to be responsible for standing in for the Chairman in the event of their absence, their being
temporary unable to fulfil their duties, their resignation or death, or the non-renewal of their appointment. If the Chairman is
temporary unable to fulfil their duties, they will stand in for them solely for the duration of this situation; in the other cases,
they will stand in for the Chairman until the election of a new Chairman.

meetings convened by the Chairman as often as the interests of the company renders this necessary. They will be held at the registered
office or at the place indicated in the notice of meeting. Meetings shall be convened by any means, even verbally, three (3) days
in advance; they may also take place without delay if all the Board members agree to this.



Meetings of the Board of Directors shall
be chaired by the Chairman of the Board of Directors. If the Chairman is absent, the Board of Directors shall appoint, for each
meeting, one of its members to chair the meeting; if the votes cast to appoint the chairman of the meeting are tied, the meeting
shall be chaired by the oldest of the Board members voted for.

If no Board meeting has been held for over
two (2) months, at least one-third (1/3) of the members of the Board of Directors may request the Chairman to convene a meeting
with a predetermined agenda. The Managing Director may also request the Chairman to convene a Board of Directors' meeting with
a predetermined agenda. The Chairman will be obliged to accede to such requests.

who shall be appointed in accordance with the provisions of the Labour Code, must be invited to attend all Board of Directors'
meetings.



An attendance register shall be kept, and
minutes shall be drawn up after each meeting.



Board meetings can only take valid decisions
if at least half the members of the Board of Directors are present.

of the members present or represented.

conferencing or telecommunication means that are compliant with the regulations in force will be deemed to be present.



Any Board member may, even by letter, telegram
or fax, give a proxy to another Board member to represent them at a Board meeting, but no Board member may hold more than one proxy
at a meeting.

Board of Directors' meetings shall be validly certified as being true copies by the Chairman of the Board of Directors, the Managing

of the company, and through its decisions rule on company matters.



In its relations with third parties, the
company is bound by all actions taken by the Board of Directors, even if they do not come within the scope of the company's purpose,
unless it can prove that the third party concerned knew that the action in question lay outwith this scope or could not be unaware
of it under the circumstances, mere publication of the Articles of Association being insufficient to constitute such proof.



9





The Board of Directors shall carry out the
checks and verifications that it deems appropriate. Each Board member shall receive all the information necessary for them to fulfil
their mission, and may have any documents that they deem of utility communicated to them.



In addition, the Board of Directors shall

or by another natural person appointed by the Board of Directors, who shall have the title of Managing Director.



Changing the method of ensuring the company's
general management will not lead to amendment of the Articles of Association.

the Managing Director will be applicable to them. They shall have the title of Chairman and Managing Director.



Article 16 - General Management

from among its members or outside of them, a Managing Director, who must be a natural person aged under sixty five (65). The Managing
Director shall have the widest possible powers to act in all circumstances in the name of the company.

or her powers within the limits of the company's purpose and subject to the powers that the law expressly attributes to shareholders'
meetings and to the Board of Directors. He or she represents the company in its relations with third parties. The company will
be bound even by actions taken by the Managing Director that lie outwith the scope of the company's purpose, unless the company
can prove that the third party concerned knew that the action in question lay outwith this scope or could not be unaware of it
under the circumstances, mere publication of the Articles of Association being insufficient to constitute such proof.



Decisions taken by the Board of Directors
that limit the powers of the Managing Director will not be enforceable on third parties.



At the suggestion of the Managing Director,
the Board of Directors may appoint one or more natural persons to be responsible for assisting the Managing Director, who shall
have the title of Deputy Managing Director. The number of Deputy Managing Directors cannot exceed five.



The Deputy Managing Directors must be aged
under sixty five (65). In agreement with the Managing Director, the Board of Directors shall determine the scope and duration of
the powers granted to the Deputy Managing Director(s). Vis-à-vis third parties, the Deputy Managing Directors shall have
the same powers as the Managing Director.



10





The Managing Director may be removed from
office at any time by the Board of Directors. The same applies, at the proposal of the Managing Director, to Deputy Managing Directors.
If removal from office is decided on without any valid reason(s) for this, this may result in damages being due, except when the
Managing Director is also the Chairman of the Board of Directors.



If the Managing Director ceases to perform
or is prevented from performing their duties, the Deputy Managing Directors shall retain their tasks, duties and responsibilities
until the appointment of the new Managing Director, unless decided otherwise by the Board.
