a)    By resolution of the general shareholders’ meeting dated April 23, 2014, which shall become effective on the date of
announcement of the resolution’s effectiveness in the Annexes to the Belgian State Gazette, authorization was granted to the Management Board to increase the company capital in one or more tranches for a maximum total amount equal to the amount
of the company capital after confirmation that the “First Capital Increase” has been realized, referred to in the second resolution of the general shareholders’ meeting held on April 23, 2014 (the “First Capital
Increase”).  
 The Management Board may only exercise the authorization granted to it for a period of five
(5) years counting from the announcement in the Annexes to the Belgian State Gazette of this authorization. 
 This authorization may be
renewed in accordance with applicable statutory provisions. 
 b)    The capital increases resolved by virtue of this authorization can
be implemented as determined by the Management Board, for example: 

	 	–	by means of contributions in cash or in kind within the limits allowed by the Belgian Companies Code, 

	 	–	by conversion of reserves and issue premiums, 

	 	–	with or without issuance of new securities, 

	 	–	by issuance of shares, with or without voting rights, 

	 	–	by issuance of convertible bonds, whether or not of subordinate rank, 

	 	–	by issuance of warrants (at no charge or for a specific issue price), 

	 	–	by issuance of bonds to which warrants or other transferable securities are attached, 

	 	–	by issuance of other securities, such as shares as part of a stock option plan. 

 c)    In
conformity with Article 606 of the Belgian Companies Code, the Management Board is not permitted to use the authorization for capital increases via (i) contribution in kind, except by a 10% shareholder, (ii) issuance below a fractional
value, (iii) issuance of warrants primarily intended for one or more particular persons other than staff members. 

 d)    The Management Board is likewise specifically authorized, in case of a public takeover
bid for securities issued by the company, to increase the capital in any form, including a capital increase in which the preferential subscription right of shareholders is limited or withdrawn, under the terms and conditions provided in Article 607
of the Belgian Companies Code. 
 This authorization is granted for a period of three (3) years counting from the extraordinary general
shareholders’ meeting held on April 23, 2014. 
 This authorization may be renewed for the same period of time by resolution of the
general meeting according to the rules for amendment of the bylaws. 
 The capital increases resolved under this authorization shall be added
onto the remaining portion of the authorized capital referred to in subparagraph a). 
 e)    Any issue premiums payable upon
subscription to a capital increase within the framework of the authorized capital will be recorded by the Management Board in an undistributable account entitled “Issue Premiums” which will extend protection to third parties to the same
extent as the company capital and which, except for the option of converting this reserve into capital, may only be disposed of by resolution at the general shareholders’ meeting, deliberating according to the rules applicable to bylaw
amendments. 
 f)    The Management Board is also authorized to limit or cancel the preferential subscription rights in the interest of
the company. It can do this for the benefit of one or more particular persons, even if they are not staff members of the company or its subsidiaries, on condition of compliance with the provisions of the law, including in the issue of warrants. It
may also provide that in the respective case upon recognition of new shares priority will still be granted to the prior shareholders. 

g)    The Management Board is authorized, with right of substitution, to bring the bylaws of the company into conformity with the
resolutions for the capital increase within the scope of the authorized capital. 
 ARTICLE 7: Capital increase—preferential subscription right.

 a)    With reservation of the possibility of a capital increase within the limits of an authorized capital by resolution of the
Management Board, an increase of the company capital can be resolved only by an extraordinary general meeting in the presence of a notary in conformity with the provisions of the Belgian Companies Code. 

b)    In every capital increase by contribution of cash, the shareholders shall enjoy a preferential subscription right in conformity with
Article 592 et seqq. of the Belgian Companies Code and the new shares, convertible bonds and warrants must be offered first to the shareholders, in proportion to the percentage of the capital represented by their shares. 

The period during which the preferential subscription right can be exercised shall be determined by the general shareholders’ meeting or,
if necessary, by the Management Board, and it may not be shorter than fifteen days counting from the starting date of the subscription period. 

The Management Board may decide that the full or partial non-exercise by the shareholders of their preferential right shall have the
consequence that the proportional shares of the shareholders who already exercised their preferential subscription right will be increased; it shall also determine the manner of this subscription. The Management Board shall likewise be entitled,
under terms and conditions that it shall determine, to enter into all agreements in order to ensure the subscription of all or part of the shares to be placed. 

 If a right of use (“vruchtgebruik”) is granted over the share , then the
preferential subscription right shall belong to the usufructuary unless otherwise agreed. The newly acquired shares, convertible bonds and warrants belong to him in full ownership, subject to eventual compensation to the bare owner prior to the
exercise of the preferential subscription right. 
 For pledged shares, the preferential subscription right shall belong to the
owner-pledgor. 
 In the interests of the company and in observance of the statutory regulations in this regard, the general
shareholders’ meeting and, within the limits of the authorized capital, the Management Board may limit or withdraw the preferential subscription right. 

c)    The general shareholders’ meeting or, as the case may be, the management board within the limits of the authorized capital may
decide on a capital increase for the benefit of the staff, provided that the regulations of Article 609 of the Belgian Companies Code shall be followed. 

d)    If a capital increase includes some contribution in kind, a company auditor or statutory auditor shall draw up a report in addition
to a special report by the Management Board, and furthermore the regulation of Article 602 of the Belgian Companies Code shall be followed. This contribution must be immediately paid in full. 

e)    A capital increase may also be effected by reversal of reserves. The extraordinary general meeting may grant the Management Board the
authorization to increase the capital by reversal of reserves within the limits of the authorized capital. 
 f)    In case the new
shares are issued with an issue premium, it must be immediately paid in full at the time of subscription to the shares.

 A decision to decrease the capital can be made in compliance with the relevant statutory regulations. 

3. Shares and other securities 
 ARTICLE 9: Type
of securities 
 The shares and other securities of the company are and shall always remain registered in the name of the relevant
securityholder. Each security has a number. 
 A register for each category of registered securities shall be kept at the company’s

these registrations shall be issued to the holders of the securities. 
 ARTICLE 10: Shares not fully paid—payment obligation 

The obligation to make full payment of a share is unconditional and indivisible. 

If shares not fully paid up belong to several persons in joint ownership, each of them is liable for payment of the entire amount of the
requested due payments. 
 Payment or full payment shall be made at the request and time decided by the Management Board. The shareholders
shall be given notice thereof by registered letter, indicating a bank account to which the payment must be made by transfer or deposit, with exclusion of any other payment method. The shareholder shall fall into default merely by the lapse of the
period specified in the notice and interest shall be owed to the company at the statutory interest rate established at that time, increased by two points. 

 Until the requested claimable payments on a share have been made according to this provision, the
exercise of the rights associated with it shall remain suspended. 
 Premature payments on shares cannot be made without the prior consent of
the management board. 
 ARTICLE 11: Indivisibility of securities 

The securities are indivisible vis-à-vis the company. 

If a security belongs to multiple owners, or if multiple persons are entitled to a security, they may only exercise the rights associated with
such securities via a common representative. 
 The company may suspend the exercise of the rights associated with them until a single person
has been identified as owner of the security with effect in relation to the company or as their common representative. 
 All convocations,
service and other notifications by the company to the various rights holders to one security are made validly and exclusively, depending on the case, either to the person designated as owner vis-à-vis the company, or to the designated common
representative. 
 ARTICLE 12: Acquirers of rights 

The rights and obligations remain associated with a security, regardless of whose hands it is in. 

The heirs, creditors or other rights holders of a shareholder may not under any circumstances interfere with the management of the company, or
have other goods and assets of the company sealed, or demand the liquidation of the company and the division of its assets. 
 Prior to
exercising their rights, they must abide by the annual report of the company and conform to the resolutions of the general meeting. 
 ARTICLE 13: Bonds,
warrants and other financial instruments that give rights to shares 
 The company may issue secured or other bonds upon decision of the
Management Board, which shall determine the terms and conditions of the issue.

shares, of warrants or of other financial instruments that give forward rights to shares can be decided by the general shareholders’ meeting or by the Management Board within the limits of the authorized capital. 

The holders of bonds or warrants have the right to attend the general shareholders’ meeting, but only with an advisory vote.

a)    The ordinary and the special general meetings shall deliberate and make resolutions in a valid manner regardless of the number of
shares present or represented. The resolutions shall be passed by a simple majority of votes. Abstentions or blank votes and invalid votes shall be disregarded when calculating the majority. In case of a tie vote, the proposal shall be defeated.

 b)    The extraordinary general meeting must be held in the presence of a notary who shall draw up an authenticated transcript
thereof. The general meeting may only deliberate and make resolutions in a legally valid manner concerning a bylaw amendment if those in attendance at the meeting represent at least half the company capital. If the aforementioned quorum is not
reached, then a new convocation shall be necessary according to Article 558 of the Belgian Companies Code; the second meeting shall validly deliberate and make resolutions regardless of the proportion of the capital present or represented. 

An amendment of the bylaws shall be approved only if it receives three-quarters of the votes associated with the shares present or represented.
In the calculation of the required majority, the votes of those who abstained or submitted blank or invalid votes shall be viewed as nay votes. 

c)    Minutes of every general meeting shall be taken, to which the attendance list and any reports and proxies shall be attached. 

The minutes of the general shareholders’ meeting shall be signed by the members of the bureau and by the shareholders that request to do
so. 

 Copies and extracts shall be signed by two directors or by one managing director. 

d)    The shareholders may pass all resolutions unanimously and in written form that come under the authority of the general meeting, with
the exception of those that must be passed by an authenticated act. The holders of bonds, warrants or certificates defined in Article 537 of the Belgian Companies Code may take note of the resolutions. 

7. Inventory – annual financial statements – reserve – distribution of profits. 

ARTICLE 32: Accounting period – annual financial statements – annual report 

a)    The accounting period of the company shall begin each year on January 1 and end on December 31 of the same year. 

At the end of each accounting period, the accounts and records are closed, and the Management Board draws up the inventory and the annual
financial statements in accordance with relevant statutory regulations. 
 The directors also draw up an annual report, as the case may be,
in which they give an account of their policies. 
 b)    For fifteen days prior to the ordinary general meeting, which must be convened
within six months after the close of the accounting period, the shareholders may inspect the annual financial statements, and other documents mentioned in the Belgian Companies Code, at the registered office of the company. 

c)    After approval of the annual financial statements, the general meeting in a separate vote resolves upon the approval of the actions
of the directors and any statutory auditor. 
 ARTICLE 33: Appropriation of the profits – reserve 

The surplus shown in the income statement comprises the net profit to be determined for the accounting period. 

From this profit, at least one-twentieth is taken in advance to form the statutory reserve, until it amounts to one-tenth of the company
capital. 
 The general meeting shall resolve freely upon the remaining appropriation of the balance of this net income, by a simple majority
vote, based on a proposal by the Management Board. 
 In accordance with Article 615 of the Belgian Companies Code, the general
shareholders’ meeting may decide to appropriate this balance for redemption of capital by repayment at par value of the shares to be allocated by lottery. 

No distribution will be made if the net assets on the closing date of the last accounting period, as appears from the annual financial
statements, are lower, or as a result of a distribution would be lower, than the amount of the paid-up capital or – if this is higher – than the called-up share capital plus all reserves that cannot be paid out according to the law or the
bylaws, and in addition, Article 617 of the Belgian Companies Code must be followed. 
 ARTICLE 34: Payout of dividends – interim dividends

 a)    The Management Board shall determine the location, time and manner in which dividends will be paid out. 

b)    The Management Board has the authority to pay out an interim dividend on the result of the accounting period. This distribution may
only occur on the profit of the current accounting period in progress, reduced, as the case may be, by the loss carried forward or increased by the profit carried forward, without withdrawal from the established reserves and in observance of the
reserves that must be formed by virtue of a provision of the law or bylaws. In addition, the regulation of Article 618 of the Belgian Companies Code shall be followed. 

 8. Dissolution – liquidation 

ARTICLE 35: Dissolution 
 A resolution for
the voluntary dissolution of the company can only be made by an extraordinary general shareholders’ meeting and on condition of compliance with the relevant statutory regulations. 

The company shall continue by law to exist as a legal entity after dissolution prior to its liquidation, until the liquidation is complete.

 ARTICLE 36: Appointment and authority of liquidators 

a)    If no liquidators have been appointed, then the directors in office at the time of dissolution shall by law act as liquidators. 

b)    If a legal entity is appointed as liquidator, the natural person who represents it must be indicated in the appointment resolution
prior to the performance of the liquidation. Any change in this indication must be disclosed in the Annexes to the Belgian State Gazette. 

c)    Nonetheless, the liquidators shall assume their function only after the Commercial Court has confirmed their appointment following
the resolution by the general meeting, in conformity with the provisions of the Belgian Companies Code. 
 d)    The general meeting of
the dissolved company may appoint and discharge one or more liquidators at any time by a simple majority vote. If there are multiple liquidators, the general meeting shall decide whether the liquidators shall represent the company individually,
jointly, or as a body. 
 ARTICLE 37: Authorities of the liquidators 

a)    The liquidators shall be authorized to take all actions cited in Articles 186, 187, and 188 of the Belgian Companies Code, without
requiring a prior authorization from the general meeting, unless the general meeting in a simple majority vote makes a divergent resolution. 

b)    The liquidators shall submit to the Clerk’s Office of the Commercial Court a comprehensive status report on the liquidation in
the seventh and the thirteenth months after the start of liquidation, prepared at the end of the sixth and twelfth month of the liquidation year, in conformity with the provisions of the Belgian Companies Code. As of the second year of the
liquidation, the comprehensive report must be submitted only for the year. 
 c)    Every year, the liquidators must present to the
ordinary general meeting the proceeds of the liquidation, stating the reasons why it was not possible to complete the liquidation. Each year they shall likewise draw up annual financial statements. 

d)    The annual report shall be published in compliance with the relevant statutory regulations. 

ARTICLE 38: Method of liquidation 
 After
payment of all debts, charges and expenses of liquidation or after consignation of the necessary funds to satisfy them, the liquidators shall distribute the net assets, in cash or securities, among the shareholders in proportion to the number of
shares that they own. 

 9. General Terms and Conditions 

ARTICLE 39: Election of domicile: 
 All
directors, statutory auditors and liquidators whose place of domicile is unknown shall be deemed to elect domicile at the registered office of the company, where all summonses, service and notifications can be made regarding the matters of the
company.
