II – SHARE CAPITAL AND SHARES



Article

The share
capital is set at the sum of SEVEN MILLION EIGHT HUNDRED FIFTY FIVE THOUSAND SIX HUNDRED TWENTY-ONE EUROS AND TEN CENTIMES(€7,855,621.10), divided into SEVENTY-EIGHT MILLION FIVE HUNDRED FIFTY SIX THOUSAND AND TWO HUNDRED ELEVEN (78’556’211)

Article

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

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

Article

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.

SECTION
III – ADMINISTRATION OF THE COMPANY



Article
12 - Board of Directors



1.
The company shall be administered by a Board of Directors made up of natural persons or legal entities, which shall have between
three and eighteen members, that shall be appointed by general meetings.



Legal entities
must, at the time of their appointment, appoint a natural person as their permanent representative on the Board of Directors.
The duration of the permanent 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.



The duration
of the term of office of Board members shall be one (1) year, a year being the period which separates two consecutive annual ordinary
general meetings. A Board member's term of office will end at the end of the shareholders' ordinary general meeting called to
approve the accounts for the previous financial year.



Board members
shall always be eligible for reappointment; they may be removed from office at any time by a decision taken by a shareholders'
general meeting.



If one or
more seats on the Board of Directors fall vacant as a result of death or resignation, the Board of Directors may, between two
general meetings, make provisional appointments. Board members appointed in replacement of another Board member whose appointed
term of office has not yet expired, will only remain in office for the remainder of their predecessor's appointed term of office.



Appointments
made by the Board of Directors by virtue of the preceding paragraph will be subject to ratification by the next ordinary general
meeting.



7






If an appointment
is not ratified, prior decisions and actions taken by the Board will nonetheless remain valid.



When the
number of Board members falls below the legal minimum, the remaining Board members must immediately convene an ordinary general
meeting with a view to appointing new Board members.



The Board
members must not have reached the age of seventy five (75). When a board member has reached this age, his mandate continues until
his assigned term.



2.
The Board of Directors shall elect a Chairman from among its members, whose remuneration it shall determine. The Chairman, who
must be a natural person, shall be appointed for a duration which cannot extend beyond their term of office as a Board member.
They shall be eligible for reappointment.



The Board
of Directors may be removed from office at any time. Any conflicting provision will be deemed to have not been written.



The Chairman
must not have reached the age of seventy five (75). When they reach this age, they will automatically be deemed to have resigned.
Their term of office will continue however until the next Board of Directors' meeting, during which their successor will be appointed.
Subject to this provision, 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.



3.
The Chairman of the Board of Directors organizes and directs the Board's work, and gives an account thereof to general meetings.
They ensure the satisfactory operation of the company's various bodies, and in particular ensure that the Board members are in
a position to fulfil their mission.



Article
13 - Decisions taken by the Board of Directors



The Board
of Directors shall meet at Board 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.



8






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.



If a Works
Council exists, its representatives, 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.



Decisions
shall be taken by a majority vote of the members present or represented.



Internal
rules adopted by the Board of Directors may, among other things, stipulate that when calculating the quorum and majority, Board
members that attend Board meetings by video 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.



Copies of
or excerpts from the minutes of Board of Directors' meetings shall be validly certified as being true copies by the Chairman of
the Board of Directors, the Managing Director, the Deputy Managing Directors, the Managing Director temporarily assuming the duties
of the Chairman, or a person who has been empowered for that purpose.



Board members,
and anyone attending Board of Directors' meetings, will be obliged to maintain discretion vis-à-vis information of a confidential
nature presented as such during a Board meeting.



Article
14 - The Board of Directors' powers



The Board
of Directors shall determine the orientations of the company's activity and ensure their implementation. Subject to the powers
expressly attributed by law to shareholders' meetings, and within the limits of the company's purpose, it shall deal with all
questions concerning the satisfactory running 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

9




circumstances, mere publication of the Articles of Association being insufficient
to constitute such proof.



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 exercise the special powers granted to it by the law.



Article
15 - Method of ensuring the general management of the company



In accordance
with the legislation in force, the general management of the company shall be assumed, under their responsibility, either by the
Chairman of the Board of Directors, 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.



When the
general management of the company is ensured by the Chairman, legislative and regulatory provisions and the provisions of the
Article of Association relating to the Managing Director will be applicable to them. They shall have the title of Chairman and
Managing Director.



Article
16 - General Management



The Board
of Directors shall appoint, either 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.



The Managing
Director shall exercise his 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

10




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.
