 DEPOSIT AGREEMENT 

DEPOSIT AGREEMENT, dated as of [DATE], 2015, by and among (i) CELYAD SA, a company organized and existing under the laws of
the Kingdom of Belgium, and its successors (the “Company”), (ii) CITIBANK, N.A., a national banking association organized under the laws of the United States of America acting in its capacity as depositary, and any successor
depositary hereunder (the “Depositary”), and (iii) all Holders and Beneficial Owners of American Depositary Shares issued hereunder (all such capitalized terms as hereinafter defined). 

W I T N E S S E T H     T H A T: 

WHEREAS, the Company desires to establish with the Depositary an ADR facility to provide for the deposit of the Shares (as hereinafter
defined) and the creation of American Depositary Shares representing the Shares so deposited and for the execution and delivery of American Depositary Receipts (as hereinafter defined) evidencing such American Depositary Shares; and 

WHEREAS, the Depositary is willing to act as the Depositary for such ADR facility upon the terms set forth in the Deposit Agreement (as
hereinafter defined); and 
 WHEREAS, any American Depositary Receipts issued pursuant to the terms of the Deposit Agreement are to
be substantially in the form of Exhibit A attached hereto, with appropriate insertions, modifications and omissions, as hereinafter provided in the Deposit Agreement; and 

WHEREAS, the Shares are listed on the Euronext Brussels and Euronext Paris, and American Depositary Shares to be issued pursuant to the
terms of the Deposit Agreement are to be listed for trading on Nasdaq; and 
 WHEREAS, the Board of Directors of the Company (or an
authorized committee thereof) has duly approved the establishment of an ADR facility upon the terms set forth in the Deposit Agreement, the execution and delivery of the Deposit Agreement on behalf of the Company, and the actions of the Company and
the transactions contemplated herein. 
 NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, the parties hereto agree as follows: 
 ARTICLE I 

DEFINITIONS 
 All
capitalized terms used, but not otherwise defined, herein shall have the meanings set forth below, unless otherwise clearly indicated: 

Section 1.1 “ADS Record Date” shall have the meaning given to such term in Section 4.9. 

  
 1 








 Section 1.2 “Affiliate” shall have the meaning
assigned to such term by the Commission (as hereinafter defined) under Regulation C promulgated under the Securities Act (as hereinafter defined), or under any successor regulation thereto. 

Section 1.3 “American Depositary Receipt(s)”, “ADR(s)” and
“Receipt(s)” shall mean the certificate(s) issued by the Depositary to evidence the American Depositary Shares issued under the terms of the Deposit Agreement in the form of Certificated ADS(s) (as hereinafter defined), as
such ADRs may be amended from time to time in accordance with the provisions of the Deposit Agreement. An ADR may evidence any number of ADSs and may, in the case of ADSs held through a central depository such as DTC, be in the form of a
“Balance Certificate.” 
 Section 1.4 “American Depositary Share(s)” and
“ADS(s)” shall mean the rights and interests in the Deposited Property (as hereinafter defined) granted to the Holders and Beneficial Owners pursuant to the terms and conditions of the Deposit Agreement and, if issued as
Certificated ADS(s) (as hereinafter defined), the ADR(s) issued to evidence such ADSs. ADS(s) may be issued under the terms of the Deposit Agreement in the form of (a) Certificated ADS(s) (as hereinafter defined), in which case the ADS(s) are
evidenced by ADR(s), or (b) Uncertificated ADS(s) (as hereinafter defined), in which case the ADS(s) are not evidenced by ADR(s) but are reflected on the direct registration system maintained by the Depositary for such purposes under the terms
of Section 2.13. Unless otherwise specified in the Deposit Agreement or in any ADR, or unless the context otherwise requires, any reference to ADS(s) shall include Certificated ADS(s) and Uncertificated ADS(s), individually or collectively, as
the context may require. Each ADS shall represent the right to receive, and to exercise the beneficial ownership interests in, the number of Shares specified in the form of ADR attached hereto as Exhibit A (as amended from time to time) that
are on deposit with the Depositary and/or the Custodian, subject, in each case, to the terms and conditions of the Deposit Agreement and the applicable ADR (if issued as a Certificated ADS), until there shall occur a distribution upon Deposited
Securities referred to in Section 4.2 or a change in Deposited Securities referred to in Section 4.11 with respect to which additional ADSs are not issued, and thereafter each ADS shall represent the right to receive, and to exercise the
beneficial ownership interests in, the applicable Deposited Property on deposit with the Depositary and the Custodian determined in accordance with the terms of such Sections, subject, in each case, to the terms and conditions of the Deposit
Agreement and the applicable ADR (if issued as a Certificated ADS). 
 Section 1.5 “Applicant”
shall have the meaning given to such term in Section 5.10. 
 Section 1.6 “Beneficial Owner”
shall mean, as to any ADS, any person or entity having a beneficial interest deriving from the ownership of such ADS. Notwithstanding anything else contained in the Deposit Agreement, any ADR(s) or any other instruments or agreements relating to the
ADSs and the corresponding Deposited Property, the Depositary, the Custodian and their respective nominees are intended to be, and shall at all times during the term of the Deposit Agreement be, the record holders only of the Deposited Property
represented by the ADSs for the benefit of the Holders and Beneficial Owners of the corresponding ADSs. The Depositary, on its own behalf and on behalf of the Custodian and their respective nominees, disclaims any beneficial ownership interest in
the Deposited Property held on behalf of the 

  
 2 








 
Holders and Beneficial Owners of ADSs. The beneficial ownership interests in the Deposited Property are intended to be, and shall at all times during the term of the Deposit Agreement continue to
be, vested in the Beneficial Owners of the ADSs representing the Deposited Property. The beneficial ownership interests in the Deposited Property shall, unless otherwise agreed by the Depositary, be exercisable by the Beneficial Owners of the ADSs
only through the Holders of such ADSs, by the Holders of the ADSs (on behalf of the applicable Beneficial Owners) only through the Depositary, and by the Depositary (on behalf of the Holders and Beneficial Owners of the corresponding ADSs) directly,
or indirectly through the Custodian or their respective nominees, in each case upon the terms of the Deposit Agreement and, if applicable, the terms of the ADR(s) evidencing the ADSs. A Beneficial Owner of ADSs may or may not be the Holder of such
ADSs. A Beneficial Owner shall be able to exercise any right or receive any benefit hereunder solely through the person who is the Holder of the ADSs owned by such Beneficial Owner. Unless otherwise identified to the Depositary, a Holder shall be
deemed to be the Beneficial Owner of all the ADSs registered in his/her/its name. 
 Section 1.7 “Certificated
ADS(s)” shall have the meaning set forth in Section 2.13. 
 Section 1.8
“Commission” shall mean the Securities and Exchange Commission of the United States or any successor governmental agency thereto in the United States.

custodian of Deposited Property pursuant to the Deposit Agreement, and (iii) any other entity that may be appointed by the Depositary pursuant to the terms of Section 5.5 as successor, substitute or additional custodian hereunder. The term
“Custodian” shall mean any Custodian individually or all Custodians collectively, as the context requires. 

Section 1.11 “Deliver” and “Delivery” shall mean (x) when used in
respect of Shares and other Deposited Securities in registered form, a record of transfer of ownership in the register of the relevant registered securities, (y) when used in respect of Shares and other Deposited Securities in
dematerialized form (book-entry form), the book-entry transfer and recordation of such securities on the books of any Settlement System (as hereinafter defined), and (z) when used in respect of ADSs, either (i) the physical
delivery of ADR(s) evidencing the ADSs, or (ii) the book-entry transfer and recordation of ADSs on the books of the Depositary or any book-entry settlement system in which the ADSs are settlement-eligible. 

Section 1.12 “Deposit Agreement” shall mean this Deposit Agreement and all exhibits hereto, as the
same may from time to time be amended and supplemented from time to time in accordance with the terms of the Deposit Agreement.

national banking association organized under the laws of the United States, in its capacity as depositary under the terms of the Deposit Agreement, and any successor depositary hereunder.

property held on deposit by the Depositary and the Custodian in respect of the ADSs or the Deposited Securities under the terms of the Deposit Agreement, subject, in the case of cash, to the provisions of Section 4.8. All Deposited Property
shall be held by Custodian, the Depositary and their respective nominees for the benefit of the Holders and Beneficial Owners of the ADSs representing the Deposited Property. The Deposited Property is not intended to, and shall not, constitute
proprietary assets of the Depositary, the Custodian or their nominees. Beneficial ownership in the Deposited Property is intended to be, and shall at all times during the term of the Deposit Agreement continue to be, vested in the Beneficial Owners
of the ADSs representing the Deposited Property. Notwithstanding the foregoing, the collateral delivered in connection with Pre-Release Transactions described in Section 5.10 shall not constitute Deposited Property.

ADSs credited to its account at DTC, or of the ADSs in respect of which the DTC Participant is otherwise acting, such DTC Participant shall be deemed, for all purposes hereunder, to have all requisite authority to act on behalf of the Beneficial
Owner(s) of the ADSs credited to its account at DTC or in respect of which the DTC Participant is so acting.

 ARTICLE II 

APPOINTMENT OF DEPOSITARY; FORM OF RECEIPTS; 

DEPOSIT OF SHARES; EXECUTION AND 

DELIVERY, TRANSFER AND SURRENDER OF RECEIPTS 

Section 2.1 Appointment of Depositary. The Company hereby appoints the Depositary as depositary for the Deposited Property
and hereby authorizes and directs the Depositary to act in accordance with the terms and conditions set forth in the Deposit Agreement and the applicable ADRs. Each Holder and each Beneficial Owner, upon acceptance of any ADSs (or any interest
therein) issued in accordance with the terms and conditions of the Deposit Agreement shall be deemed for all purposes to (a) be a party to and bound by the terms of the Deposit Agreement and the applicable ADR(s), and (b) appoint the
Depositary its attorney-in-fact, with full power to delegate, to act on its behalf and to take any and all actions contemplated in the Deposit Agreement and the applicable ADR(s), to adopt any and all procedures necessary to comply with applicable
law and to take such action as the Depositary in its sole discretion may deem necessary or appropriate to carry out the purposes of the Deposit Agreement and the applicable ADR(s), the taking of such actions to be the conclusive determinant of the
necessity and appropriateness thereof. 
 Section 2.2 Form and Transferability of ADSs. 

(a) Form. Certificated ADSs shall be evidenced by definitive ADRs which shall be engraved, printed, lithographed or produced in
such other manner as may be agreed upon by the Company and the Depositary. ADRs may be issued under the Deposit Agreement in denominations of any whole number of ADSs. The ADRs shall be substantially in the form set forth in Exhibit A to the
Deposit Agreement, with any appropriate insertions, modifications and omissions, in each case as otherwise contemplated in the Deposit Agreement or required by law. ADRs shall be (i) dated, (ii) signed by the manual or facsimile signature
of a duly authorized signatory of the Depositary, (iii) countersigned by the manual or facsimile signature of a duly authorized signatory of the Registrar, and (iv) registered in the books maintained by the Registrar for the registration
of issuances and transfers of ADSs. No ADR and no Certificated ADS evidenced thereby shall be entitled to any benefits under the Deposit Agreement or be valid or enforceable for any purpose against the Depositary or the Company, unless such ADR
shall have been so dated, signed, countersigned and registered. ADRs bearing the facsimile signature of a duly-authorized signatory of the Depositary or the Registrar, who at the time of signature was a duly-authorized signatory of the Depositary or
the Registrar, as the case may be, shall bind the Depositary, notwithstanding the fact that such signatory has ceased to be so authorized prior to the delivery of such ADR by the Depositary. The ADRs shall bear a CUSIP number that is different from
any CUSIP number that was, is or may be assigned to any depositary receipts previously or subsequently issued pursuant to any other arrangement between the Depositary (or any other depositary) and the Company and which are not ADRs outstanding
hereunder. 
 (b) Legends. The ADRs may be endorsed with, or have incorporated in the text thereof, such legends or recitals
not inconsistent with the provisions of the Deposit Agreement as may be (i) necessary to enable the Depositary and the Company to perform their respective 

  
 7 








 
obligations hereunder, (ii) required to comply with any applicable laws or regulations, or with the rules and regulations of any securities exchange or market upon which ADSs may be traded,
listed or quoted, or to conform with any usage with respect thereto, (iii) necessary to indicate any special limitations or restrictions to which any particular ADRs or ADSs are subject by reason of the date of issuance of the Deposited
Securities or otherwise, or (iv) required by any book-entry system in which the ADSs are held. Holders and Beneficial Owners shall be deemed, for all purposes, to have notice of, and to be bound by, the terms and conditions of the legends set
forth, in the case of Holders, on the ADR registered in the name of the applicable Holders or, in the case of Beneficial Owners, on the ADR representing the ADSs owned by such Beneficial Owners. 

(c) Title. Subject to the limitations contained herein and in the ADR, title to an ADR (and to each Certificated
ADS evidenced thereby) shall be transferable upon the same terms as a certificated security under the laws of the State of New York, provided that, in the case of Certificated ADSs, such ADR has been properly endorsed or is accompanied by proper
instruments of transfer. Notwithstanding any notice to the contrary, the Depositary and the Company may deem and treat the Holder of an ADS (that is, the person in whose name an ADS is registered on the books of the Depositary) as the absolute owner
thereof for all purposes. Neither the Depositary nor the Company shall have any obligation nor be subject to any liability under the Deposit Agreement or any ADR to any holder or any Beneficial Owner unless, in the case of a holder of ADSs, such
holder is the Holder registered on the books of the Depositary or, in the case of a Beneficial Owner, such Beneficial Owner, or the Beneficial Owner’s representative, is the Holder registered on the books of the Depositary. 

(d) Book-Entry Systems. The Depositary shall make arrangements for the
acceptance of the ADSs into DTC. All ADSs held through DTC will be registered in the name of the nominee for DTC (“Cede & Co.” or a successor nominee). As such, the nominee for DTC will be the only “Holder” of all ADSs
held through DTC. Unless issued by the Depositary as Uncertificated ADSs, the ADSs registered in the name of Cede & Co. will be evidenced by one or more ADR(s) in the form of a “Balance Certificate,” which will provide that it
represents the aggregate number of ADSs from time to time indicated in the records of the Depositary as being issued hereunder and that the aggregate number of ADSs represented thereby may from time to time be increased or decreased by making
adjustments on such records of the Depositary and of DTC or its nominee as hereinafter provided. Citibank, N.A. (or such other entity as is appointed by DTC or its nominee) may hold the “Balance Certificate” as custodian for DTC. Each
Beneficial Owner of ADSs held through DTC must rely upon the procedures of DTC and the DTC Participants to exercise or be entitled to any rights attributable to such ADSs. The DTC Participants shall for all purposes be deemed to have all requisite
power and authority to act on behalf of the Beneficial Owners of the ADSs held in the DTC Participants’ respective accounts in DTC and the Depositary shall for all purposes be authorized to rely upon any instructions and information given to it
by DTC Participants. So long as ADSs are held through DTC or unless otherwise required by law, ownership of beneficial interests in the ADSs registered in the name of the nominee for DTC will be shown on, and transfers of such ownership will be
effected only through, records maintained by (i) DTC or its nominee (with respect to the interests of DTC Participants), or (ii) DTC Participants or their nominees (with respect to the interests of clients of DTC Participants).

 Section 2.3 Deposit of Shares. Subject to the terms and
conditions of the Deposit Agreement and applicable law, Shares or evidence of rights to receive Shares (other than Restricted Securities) may be deposited by any person (including the Depositary in its individual capacity but subject, however, in
the case of the Company or any Affiliate of the Company, to Section 5.7) at any time, whether or not the transfer books of the Company or any Settlement System, if any, are closed, by Delivery of the Shares to the Custodian. Every deposit of
Shares shall be accompanied by the following: (A) (i) in the case of Shares in registered form, evidence of the record of the holding in the name of the Custodian in the Company’s shareholders register, in a form reasonably
satisfactory to the Custodian, and (ii) in the case of Shares in dematerialized form and delivered by book-entry transfer and recordation, confirmation of such book-entry transfer and recordation in the books of any Settlement System, to
the Custodian or that irrevocable instructions have been given to cause such Shares to be so transferred and recorded, (B) such certifications and payments (including, without limitation, the Depositary’s fees and related charges) and
evidence of such payments (including, without limitation, stamping or otherwise marking such Shares by way of receipt) as may be reasonably required by the Depositary or the Custodian in accordance with the provisions of the Deposit Agreement and
applicable law, (C) if the Depositary so requires, a written order directing the Depositary to issue and deliver to, or upon the written order of, the person(s) stated in such order the number of ADSs representing the Shares so deposited,
(D) evidence reasonably satisfactory to the Depositary (which may be an opinion of counsel) that all necessary approvals have been granted by, or there has been compliance with the rules and regulations of, any applicable governmental agency in
the Kingdom of Belgium, and (E) if the Depositary so requires, (i) an agreement, assignment or instrument reasonably satisfactory to the Depositary or the Custodian which provides for the prompt transfer by any person in whose name the
Shares are or have been recorded to the Custodian of any distribution, or right to subscribe for additional Shares or to receive other property in respect of any such deposited Shares or, in lieu thereof, such indemnity or other agreement as shall
be reasonably satisfactory to the Depositary or the Custodian and (ii) if the Shares are registered in the name of the person on whose behalf they are presented for deposit, a proxy or proxies entitling the Custodian to exercise voting rights
in respect of the Shares for any and all purposes until the Shares so deposited are registered in the name of the Depositary, the Custodian or any nominee. 

Without limiting any other provision of the Deposit Agreement, the Depositary shall instruct the Custodian not to, and the Depositary shall
not knowingly, accept for deposit (a) any Restricted Securities (except as contemplated by Section 2.14) nor (b) any fractional Shares or fractional Deposited Securities nor (c) a number of Shares or Deposited Securities which
upon application of the ADS to Shares ratio would give rise to fractional ADSs. No Shares shall be accepted for deposit unless accompanied by evidence, if any is required by the Depositary, that is reasonably satisfactory to the Depositary or the
Custodian that all conditions to such deposit have been satisfied by the person depositing such Shares under the laws and regulations of the Kingdom of Belgium and any necessary approval has been granted by any applicable governmental body in the
Kingdom of Belgium, if any. The Depositary may issue ADSs against evidence of rights to receive Shares from the Company, any agent of the Company or any custodian, registrar, transfer agent, clearing agency or other entity involved in ownership or
transaction records in respect of the Shares. Such evidence of rights shall consist of written blanket or specific guarantees of ownership of Shares furnished by the Company or any such custodian, registrar, transfer agent, clearing agency or other
entity involved in ownership or transaction records in respect of the Shares. 

  
 9 








 Without limitation of the foregoing, the Depositary shall not knowingly accept for deposit under
the Deposit Agreement (A) any Shares or other securities required to be registered under the provisions of the Securities Act, unless (i) a registration statement is in effect as to such Shares or other securities or (ii) the deposit
is made upon terms contemplated in Section 2.14, or (B) any Shares or other securities the deposit of which would violate any provisions of the Articles of Association of the Company or Belgian law. For purposes of the foregoing sentence,
the Depositary shall be entitled to rely upon representations and warranties made or deemed made pursuant to the Deposit Agreement and shall not be required to make any further investigation. The Depositary will comply with written instructions of
the Company (received by the Depositary reasonably in advance) not to accept for deposit hereunder any Shares identified in such instructions at such times and under such circumstances as may reasonably be specified in such instructions in order to
facilitate the Company’s compliance with the securities laws of the United States. 

  
 10 








 Section 2.4 Registration and Safekeeping of Deposited
Securities. The Depositary shall instruct the Custodian upon each Delivery of registered Shares being deposited hereunder with the Custodian (or other Deposited Securities pursuant to Article IV hereof), together with the other
documents above specified, to present such Shares, together with the appropriate instrument(s) of transfer or endorsement, duly stamped, to the Company for transfer and registration of the Shares (as soon as transfer and registration can be
accomplished and at the expense of the person for whom the deposit is made) in the name of the Depositary, the Custodian or a nominee of either. Deposited Securities shall be held by the Depositary, or by a Custodian for the account and to the order
of the Depositary or a nominee of the Depositary, in each case, on behalf of the Holders and Beneficial Owners, at such place(s) as the Depositary or the Custodian shall determine. Notwithstanding anything else contained in the Deposit Agreement,
any ADR(s), or any other instruments or agreements relating to the ADSs and the corresponding Deposited Property, the registration of the Deposited Securities in the name of the Depositary, the Custodian or any of their respective nominees, shall,
to the maximum extent permitted by applicable law, vest in the Depositary, the Custodian or the applicable nominee the record ownership in the applicable Deposited Securities with the beneficial ownership rights and interests in such Deposited
Securities being at all times vested with the Beneficial Owners of the ADSs representing the Deposited Securities. Notwithstanding the foregoing, the Depositary, the Custodian and the applicable nominee shall at all times be entitled to exercise the
beneficial ownership rights in all Deposited Property, in each case only on behalf of the Holders and Beneficial Owners of the ADSs representing the Deposited Property, upon the terms set forth in the Deposit Agreement and, if applicable, the ADR(s)
representing the ADSs. The Depositary, the Custodian and their respective nominees shall for all purposes be deemed to have all requisite power and authority to act in respect of Deposited Property on behalf of the Holders and Beneficial Owners of
ADSs representing the Deposited Property, and upon making payments to, or acting upon instructions from, or information provided by, the Depositary, the Custodian or their respective nominees all persons shall be authorized to rely upon such power
and authority. 
 Section 2.5 Issuance of ADSs. The Depositary has made arrangements with the Custodian for
the Custodian to confirm to the Depositary upon receipt of a deposit of Shares (i) that a deposit of Shares has been made pursuant to Section 2.3, (ii) that such Deposited Securities have been recorded in the name of the Depositary,
the Custodian or a nominee of either on the shareholders’ register maintained by or on behalf of the Company on the books of the relevant Settlement System, (iii) that all required documents have been received, and (iv) the person(s)
to whom or upon whose order ADSs are deliverable in respect thereof and the number of ADSs to be so delivered. Such notification may be made by letter, cable, telex, SWIFT message or, at the risk and expense of the person making the deposit, by
facsimile or other means of electronic transmission. Upon receiving such notice from the Custodian, the Depositary, subject to the terms and conditions of the Deposit Agreement and applicable law, shall issue the ADSs representing the Shares so
deposited to or upon the order of the person(s) named in the notice delivered to the Depositary and, if applicable, shall execute and deliver at its Principal Office Receipt(s) registered in the name(s) requested by such person(s) and evidencing the
aggregate number of ADSs to which such person(s) are entitled, but, in each case, only upon payment to the Depositary of the charges of the Depositary for accepting a deposit and issuing ADSs (as set forth in Section 5.9 and Exhibit B
hereto) and all taxes and governmental charges and fees payable in connection with such deposit and the transfer of the Shares and the issuance of the 

  
 11 








 
ADS(s). The Depositary shall only issue ADSs in whole numbers and deliver, if applicable, ADR(s) evidencing whole numbers of ADSs. Nothing herein shall prohibit any Pre-Release Transaction upon
the terms set forth in the Deposit Agreement. 
 Section 2.6 Transfer, Combination and Split-up of ADRs.

 (a) Transfer. The Registrar shall register the transfer of ADRs (and of the ADSs represented thereby) on
the books maintained for such purpose and the Depositary shall (x) cancel such ADRs and execute new ADRs evidencing the same aggregate number of ADSs as those evidenced by the ADRs canceled by the Depositary, (y) cause the Registrar to
countersign such new ADRs and (z) Deliver such new ADRs to or upon the order of the person entitled thereto, if each of the following conditions has been satisfied: (i) the ADRs have been duly Delivered by the Holder (or by a duly
authorized attorney of the Holder) to the Depositary at its Principal Office for the purpose of effecting a transfer thereof, (ii) the surrendered ADRs have been properly endorsed or are accompanied by proper instruments of transfer (including
signature guarantees in accordance with standard securities industry practice), (iii) the surrendered ADRs have been duly stamped (if required by the laws of the State of New York or of the United States), and (iv) all applicable fees and
charges of, and expenses incurred by, the Depositary and all applicable taxes and governmental charges (as are set forth in Section 5.9 and Exhibit B hereto) have been paid, subject, however, in each case, to the
terms and conditions of the applicable ADRs, of the Deposit Agreement and of applicable law, in each case as in effect at the time thereof. 

(b) Combination & Split-Up. The Registrar shall register the split-up or combination of ADRs (and of the
ADSs represented thereby) on the books maintained for such purpose and the Depositary shall (x) cancel such ADRs and execute new ADRs for the number of ADSs requested, but in the aggregate not exceeding the number of ADSs evidenced by the ADRs
canceled by the Depositary, (y) cause the Registrar to countersign such new ADRs and (z) Deliver such new ADRs to or upon the order of the Holder thereof, if each of the following conditions has been satisfied: (i) the ADRs have been
duly Delivered by the Holder (or by a duly authorized attorney of the Holder) to the Depositary at its Principal Office for the purpose of effecting a split-up or combination thereof, and (ii) all applicable fees and charges of, and expenses
incurred by, the Depositary and all applicable taxes and governmental charges (as are set forth in Section 5.9 and Exhibit B hereto) have been paid, subject, however, in each case, to the terms and conditions of the
applicable ADRs, of the Deposit Agreement and of applicable law, in each case as in effect at the time thereof. 
 (c)
Co-Transfer Agents. The Depositary may appoint one or more co-transfer agents for the purpose of effecting transfers, combinations and split-ups of ADRs at designated transfer offices on behalf of the Depositary and the
Depositary shall notify the Company in writing upon any such appointment. In carrying out its functions, a co-transfer agent may require evidence of authority and compliance with applicable laws and other requirements by Holders or persons entitled
to such ADRs and will be entitled to protection and indemnity to the same extent as the Depositary. Such co-transfer agents may be removed and substitutes appointed by the Depositary and the Depositary shall notify the Company in writing upon any
such removal or substitution. Each co-transfer agent appointed under this Section 2.6 (other than the Depositary) shall give notice in writing to the Depositary accepting such appointment and agreeing to be bound by the applicable terms of the
Deposit Agreement. 

  
 12 








 Section 2.7 Surrender of ADSs and Withdrawal of Deposited Securities.
The Holder of ADSs shall be entitled to Delivery (at the Custodian’s designated office) of the Deposited Securities at the time represented by the ADSs upon satisfaction of each of the following conditions: (i) the Holder (or a
duly-authorized attorney of the Holder) has duly Delivered ADSs to the Depositary at its Principal Office (and if applicable, the ADRs evidencing such ADSs) for the purpose of withdrawal of the Deposited Securities represented thereby, (ii) if
applicable and so required by the Depositary, the ADRs Delivered to the Depositary for such purpose have been properly endorsed in blank or are accompanied by proper instruments of transfer in blank (including signature guarantees in accordance with
standard securities industry practice), (iii) if so required by the Depositary, the Holder of the ADSs has executed and delivered to the Depositary a written order directing the Depositary to cause the Deposited Securities being withdrawn to be
Delivered to or upon the written order of the person(s) designated in such order, and (iv) all applicable fees and charges of, and expenses incurred by, the Depositary and all applicable taxes and governmental charges (as are set forth in
Section 5.9 and Exhibit B) have been paid, subject, however, in each case, to the terms and conditions of the ADRs evidencing the surrendered ADSs, of the Deposit Agreement, of the Company’s Articles of Association and of any
applicable laws and the rules of the relevant Settlement System, and to any provisions of or governing the Deposited Securities, in each case as in effect at the time thereof. 

Upon satisfaction of each of the conditions specified above, the Depositary (i) shall cancel the ADSs Delivered to it (and, if
applicable, the ADR(s) evidencing the ADSs so Delivered), (ii) shall direct the Registrar to record the cancellation of the ADSs so Delivered on the books maintained for such purpose, and (iii) shall direct the Custodian to Deliver, or
cause the Delivery of, in each case, without unreasonable delay, the Deposited Securities represented by the ADSs so canceled together with any certificate or other document of title for the Deposited Securities, or evidence of the electronic
transfer thereof (if available), as the case may be, to or upon the written order of the person(s) designated in the order delivered to the Depositary for such purpose, subject however, in each case, to the terms and conditions of the Deposit
Agreement, of the ADRs evidencing the ADSs so canceled, of the Articles of Association of the Company, of any applicable laws and of the rules of the relevant Settlement System, and to the terms and conditions of or governing the Deposited
Securities, in each case as in effect at the time thereof. 
 The Depositary shall not accept for surrender ADSs representing less than one
(1) Share. In the case of Delivery to it of ADSs representing a number other than a whole number of Shares, the Depositary shall cause ownership of the appropriate whole number of Shares to be Delivered in accordance with the terms hereof, and
shall, at the discretion of the Depositary, either (i) return to the person surrendering such ADSs the number of ADSs representing any remaining fractional Share, or (ii) sell or cause to be sold an aggregated number of fractional Shares
(represented by the ADSs so surrendered) which equal one Share or an integral multiple thereof and remit the proceeds of such sale (net of (a) applicable fees and charges of, and expenses incurred by, the Depositary and (b) taxes required
to be withheld as a result of such sale) to the person surrendering the ADSs. 

  
 13 








 Notwithstanding anything else contained in any ADR or the Deposit Agreement, the Depositary may
make delivery at the Principal Office of the Depositary of Deposited Property consisting of (i) any cash dividends or cash distributions, or (ii) any proceeds from the sale of any non-cash distributions, which are at the time held by the
Depositary in respect of the Deposited Securities represented by the ADSs surrendered for cancellation and withdrawal. At the request, risk and expense of any Holder so surrendering ADSs, and for the account of such Holder, the Depositary shall
direct the Custodian to forward (to the extent permitted by law) any Deposited Property (other than Deposited Securities) held by the Custodian in respect of such ADSs to the Depositary for delivery at the Principal Office of the Depositary. Such
direction shall be given by letter or, at the request, risk and expense of such Holder, by cable, telex or facsimile transmission. 

Section 2.8 Limitations on Execution and Delivery, Transfer, etc. of ADSs; Suspension of Delivery, Transfer, etc. 

(a) Additional Requirements. As a condition precedent to the execution and delivery, the registration of issuance,
transfer, split-up, combination or surrender, of any ADS, the delivery of any distribution thereon, or the withdrawal of any Deposited Property, the Depositary or the Custodian may require (i) payment from the depositor of Shares or presenter
of ADSs or of an ADR of a sum sufficient to reimburse it for any tax or other governmental charge and any stock transfer or registration fee with respect thereto (including any such tax or charge and fee with respect to Shares being deposited or
withdrawn) and payment of any applicable fees and charges of the Depositary as provided in Section 5.9 and Exhibit B, (ii) the production of proof reasonably satisfactory to it as to the identity and genuineness of any signature or
any other matter contemplated by Section 3.1, and (iii) compliance with (A) any laws or governmental regulations relating to the execution and delivery of ADRs or ADSs or to the withdrawal of Deposited Securities and (B) such
reasonable regulations as the Depositary and the Company may establish consistent with the provisions of the representative ADR, if applicable, the Deposit Agreement and applicable law. 

(b) Additional Limitations. The issuance of ADSs against deposits of Shares generally or against deposits of
particular Shares may be suspended, or the deposit of particular Shares may be refused, or the registration of transfer of ADSs in particular instances may be refused, or the registration of transfers of ADSs generally may be suspended, during any
period when the transfer books of the Company, the Depositary, a Registrar or a Settlement System are closed or if any such action is deemed necessary or advisable by the Depositary or the Company, in good faith, at any time or from time to time
because of any requirement of law or regulation, any government or governmental body or commission or any securities exchange on which the ADSs or Shares are listed, or under any provision of the Deposit Agreement or the representative ADR(s), if
applicable, or under any provision of, or governing, the Deposited Securities, or because of a meeting of shareholders of the Company or for any other reason, subject, in all cases, to Section 7.8. 

(c) Regulatory Restrictions. Notwithstanding any provision of the Deposit Agreement or any ADR(s) to the contrary,
Holders are entitled to surrender outstanding ADSs to withdraw the Deposited Securities associated herewith at any time subject only to (i) temporary 

  
 14 








 
delays caused by closing of the transfer books of the Depositary or the Company or a Settlement System (when applicable) or the deposit of Shares in connection with voting at a shareholders’
meeting or the payment of dividends, (ii) the payment of fees, taxes and similar charges, (iii) compliance with any U.S. or foreign laws or governmental regulations relating to the ADSs or to the withdrawal of the Deposited Securities, and
(iv) other circumstances specifically contemplated by Instruction I.A.(l) of the General Instructions to Form F-6 (as such General Instructions may be amended from time to time). 

Section 2.9 Lost ADRs, etc. In case any ADR shall be mutilated, destroyed, lost, or stolen, the Depositary shall execute
and deliver a new ADR of like tenor at the expense of the Holder (a) in the case of a mutilated ADR, in exchange of and substitution for such mutilated ADR upon cancellation thereof, or (b) in the case of a destroyed, lost or
stolen ADR, in lieu of and in substitution for such destroyed, lost, or stolen ADR, after the Holder thereof (i) has submitted to the Depositary a written request for such exchange and substitution before the Depositary has notice that the
ADR has been acquired by a bona fide purchaser, (ii) has provided such security or indemnity (including an indemnity bond) as may be required by the Depositary to save it and any of its agents harmless, and (iii) has satisfied any other
reasonable requirements imposed by the Depositary, including, without limitation, evidence reasonably satisfactory to the Depositary of such destruction, loss or theft of such ADR, the authenticity thereof and the Holder’s ownership thereof.

 Section 2.10 Cancellation and Destruction of Surrendered ADRs; Maintenance of Records. All ADRs surrendered to
the Depositary shall be canceled by the Depositary. Canceled ADRs shall not be entitled to any benefits under the Deposit Agreement or be valid or enforceable against the Depositary for any purpose. The Depositary is authorized to destroy ADRs so
canceled, provided the Depositary maintains a record of all destroyed ADRs. Any ADSs held in book-entry form (i.e., through accounts at DTC) shall be deemed canceled when the Depositary causes the number of ADSs evidenced by the Balance
Certificate to be reduced by the number of ADSs surrendered (without the need to physically destroy the Balance Certificate). 

Section 2.11 Escheatment. In the event any unclaimed property relating to the ADSs, for any reason, is in the
possession of Depositary and has not been claimed by the Holder thereof or cannot be delivered to the Holder thereof through usual channels, the Depositary shall, upon expiration of any applicable statutory period relating to abandoned property
laws, escheat such unclaimed property to the relevant authorities in accordance with the laws of each of the relevant States of the United States. 

  
 15 








 Section 2.12 Partial Entitlement ADSs. In the event any Shares are deposited
which (i) entitle the holders thereof to receive a per-share distribution or other entitlement in an amount different from the Shares then on deposit or (ii) are not fully fungible (including, without limitation, as to settlement or
trading) with the Shares then on deposit (the Shares then on deposit collectively, “Full Entitlement Shares” and the Shares with different entitlement, “Partial Entitlement Shares”), the Depositary shall
(i) cause the Custodian to hold Partial Entitlement Shares separate and distinct from Full Entitlement Shares, and (ii) subject to the terms of the Deposit Agreement, issue ADSs representing Partial Entitlement Shares which are separate
and distinct from the ADSs representing Full Entitlement Shares, by means of separate CUSIP numbering and legending (if necessary) and, if applicable, by issuing ADRs evidencing such ADSs with applicable notations thereon (“Partial
Entitlement ADSs/ADRs” and “Full Entitlement ADSs/ADRs”, respectively). If and when Partial Entitlement Shares become Full Entitlement Shares, the Depositary shall (a) give notice thereof to Holders of Partial
Entitlement ADSs and give Holders of Partial Entitlement ADRs the opportunity to exchange such Partial Entitlement ADRs for Full Entitlement ADRs, (b) cause the Custodian to transfer the Partial Entitlement Shares into the account of the Full
Entitlement Shares, and (c) take such actions as are necessary to remove the distinctions between (i) the Partial Entitlement ADRs and ADSs, on the one hand, and (ii) the Full Entitlement ADRs and ADSs on the other. Holders and
Beneficial Owners of Partial Entitlement ADSs shall only be entitled to the entitlements of Partial Entitlement Shares. Holders and Beneficial Owners of Full Entitlement ADSs shall be entitled only to the entitlements of Full Entitlement Shares. All
provisions and conditions of the Deposit Agreement shall apply to Partial Entitlement ADRs and ADSs to the same extent as Full Entitlement ADRs and ADSs, except as contemplated by this Section 2.12. The Depositary is authorized to take any and
all other actions as may be necessary (including, without limitation, making the necessary notations on ADRs) to give effect to the terms of this Section 2.12. The Company agrees to give timely written notice to the Depositary if any Shares
issued or to be issued are Partial Entitlement Shares and shall assist the Depositary with the establishment of procedures enabling the identification of Partial Entitlement Shares upon Delivery to the Custodian. 

Section 2.13 Certificated/Uncertificated ADSs. Notwithstanding any other provision of the Deposit Agreement, the
Depositary may, at any time and from time to time, issue ADSs that are not evidenced by ADRs (such ADSs, the “Uncertificated ADS(s)” and the ADS(s) evidenced by ADR(s), the “Certificated ADS(s)”). When issuing and
maintaining Uncertificated ADS(s) under the Deposit Agreement, the Depositary shall at all times be subject to (i) the standards applicable to registrars and transfer agents maintaining direct registration systems for equity securities in New
York and issuing uncertificated securities under New York law, and (ii) the terms of New York law applicable to uncertificated equity securities. Uncertificated ADSs shall not be represented by any instruments but shall be evidenced by
registration in the books of the Depositary maintained for such purpose. Holders of Uncertificated ADSs, that are not subject to any registered pledges, liens, restrictions or adverse claims of which the Depositary has notice at such time, shall at
all times have the right to exchange the Uncertificated ADS(s) for Certificated ADS(s) of the same type and class, subject in each case to applicable laws and any rules and regulations the Depositary may have established in respect of the
Uncertificated ADSs. Holders of Certificated ADSs shall, if the Depositary maintains a direct registration system for the ADSs, have the right to exchange the Certificated ADSs for Uncertificated ADSs


  
 16 








 
upon (i) the due surrender of the Certificated ADS(s) to the Depositary for such purpose and (ii) the presentation of a written request to that effect to the Depositary, subject in each
case to (a) all liens and restrictions noted on the ADR evidencing the Certificated ADS(s) and all adverse claims of which the Depositary then has notice, (b) the terms of the Deposit Agreement and the rules and regulations that the
Depositary may establish for such purposes hereunder, (c) applicable law, and (d) payment of the Depositary fees and expenses applicable to such exchange of Certificated ADS(s) for Uncertificated ADS(s). Uncertificated ADSs shall in all
material respects be identical to Certificated ADS(s) of the same type and class, except that (i) no ADR(s) shall be, or shall need to be, issued to evidence Uncertificated ADS(s), (ii) Uncertificated ADS(s) shall, subject to the terms of
the Deposit Agreement, be transferable upon the same terms and conditions as uncertificated securities under New York law, (iii) the ownership of Uncertificated ADS(s) shall be recorded on the books of the Depositary maintained for such purpose
and evidence of such ownership shall be reflected in periodic statements provided by the Depositary to the Holder(s) in accordance with applicable New York law, (iv) the Depositary may from time to time, upon notice to the Holders of
Uncertificated ADSs affected thereby, establish rules and regulations, and amend or supplement existing rules and regulations, as may be deemed reasonably necessary to maintain Uncertificated ADS(s) on behalf of Holders, provided that (a) such
rules and regulations do not conflict with the terms of the Deposit Agreement and applicable law, and (b) the terms of such rules and regulations are readily available to Holders upon request, (v) the Uncertificated ADS(s) shall not be
entitled to any benefits under the Deposit Agreement or be valid or enforceable for any purpose against the Depositary or the Company unless such Uncertificated ADS(s) is/are registered on the books of the Depositary maintained for such purpose,
(vi) the Depositary may, in connection with any deposit of Shares resulting in the issuance of Uncertificated ADSs and with any transfer, pledge, release and cancellation of Uncertificated ADSs, require the prior receipt of such documentation
as the Depositary may deem reasonably appropriate, and (vii) upon termination of the Deposit Agreement, the Depositary shall not require Holders of Uncertificated ADSs to affirmatively instruct the Depositary before remitting proceeds from the
sale of the Deposited Property represented by such Holders’ Uncertificated ADSs under the terms of Section 6.2 of the Deposit Agreement. When issuing ADSs under the terms of the Deposit Agreement, including, without limitation, issuances
pursuant to Sections 2.5, 4.2, 4.3, 4.4, 4.5 and 4.11, the Depositary may in its discretion determine to issue Uncertificated ADSs rather than Certificated ADSs, unless otherwise specifically instructed by the applicable Holder to issue Certificated
ADSs. All provisions and conditions of the Deposit Agreement shall apply to Uncertificated ADSs to the same extent as to Certificated ADSs, except as contemplated by this Section 2.13. The Depositary is authorized and directed to take any and
all actions and establish any and all procedures deemed reasonably necessary to give effect to the terms of this Section 2.13. Any references in the Deposit Agreement or any ADR(s) to the terms “American Depositary Share(s)” or
“ADS(s)” shall, unless the context otherwise requires, include Certificated ADS(s) and Uncertificated ADS(s). Except as set forth in this Section 2.13 and except as required by applicable law, the Uncertificated ADSs shall be treated
as ADSs issued and outstanding under the terms of the Deposit Agreement. In the event that, in determining the rights and obligations of parties hereto with respect to any Uncertificated ADSs, any conflict arises between (a) the terms of the
Deposit Agreement (other than this Section 2.13) and (b) the terms of this Section 2.13, the terms and conditions set forth in this Section 2.13 shall be controlling and shall govern the rights and obligations of the parties to
the Deposit Agreement pertaining to the Uncertificated ADSs. 

  
 17 








 Section 2.14 Restricted ADSs. The Depositary shall, at the request and expense
of the Company, establish procedures enabling the deposit hereunder of Shares that are Restricted Securities in order to enable the holder of such Shares to hold its ownership interests in such Restricted Shares in the form of ADSs issued under the
terms hereof (such Shares, “Restricted Shares”). Upon receipt of a written request from the Company to accept Restricted Shares for deposit hereunder, the Depositary agrees to establish procedures permitting the deposit of such
Restricted Shares and the issuance of ADSs representing the right to receive, subject to the terms of the Deposit Agreement and the applicable ADR (if issued as a Certificated ADS), such deposited Restricted Shares (such ADSs, the
“Restricted ADSs,” and the ADRs evidencing such Restricted ADSs, the “Restricted ADRs”). Notwithstanding anything contained in this Section 2.14, the Depositary and the Company may, to the extent not prohibited
by law, agree to issue the Restricted ADSs in uncertificated form (“Uncertificated Restricted ADSs”) upon such terms and conditions as the Company and the Depositary may deem necessary and appropriate. The Company shall assist the
Depositary in the establishment of such procedures and agrees that it shall take all steps necessary and reasonably satisfactory to the Depositary to ensure that the establishment of such procedures does not violate the provisions of the Securities
Act or any other applicable laws. The depositors of such Restricted Shares and the Holders of the Restricted ADSs may be required prior to the deposit of such Restricted Shares, the transfer of the Restricted ADRs and Restricted ADSs or the
withdrawal of the Restricted Shares represented by Restricted ADSs to provide such written certifications or agreements as the Depositary or the Company may require. The Company shall provide to the Depositary in writing the legend(s) to be affixed
to the Restricted ADRs (if the Restricted ADSs are to be issued as Certificated ADSs), or to be included in the statements issued from time to time to Holders of Uncertificated ADSs (if issued as Uncertificated Restricted ADSs), which legends
shall (i) be in a form reasonably satisfactory to the Depositary and (ii) contain the specific circumstances under which the Restricted ADSs, and, if applicable, the Restricted ADRs evidencing the Restricted ADSs, may be transferred or the
Restricted Shares withdrawn. The Restricted ADSs issued upon the deposit of Restricted Shares shall be separately identified on the books of the Depositary and the Restricted Shares so deposited shall, to the extent required by law, be held separate
and distinct from the other Deposited Securities held hereunder. The Restricted Shares and the Restricted ADSs shall not be eligible for Pre-Release Transactions. The Restricted ADSs shall not be eligible for inclusion in any book-entry settlement
system, including, without limitation, DTC, and shall not in any way be fungible with the ADSs issued under the terms hereof that are not Restricted ADSs. The Restricted ADSs, and, if applicable, the Restricted ADRs evidencing the Restricted ADSs,
shall be transferable only by the Holder thereof upon delivery to the Depositary of (i) all documentation otherwise contemplated by the Deposit Agreement and (ii) an opinion of counsel reasonably satisfactory to the Depositary setting
forth, inter alia, the conditions upon which the Restricted ADSs presented, and, if applicable, the Restricted ADRs evidencing the Restricted ADSs, are transferable by the Holder thereof under applicable securities laws and the transfer
restrictions contained in the legend applicable to the Restricted ADSs presented for transfer. Except as set forth in this Section 2.14 and except as required by applicable law, the Restricted ADSs and the Restricted ADRs evidencing Restricted
ADSs shall be treated as ADSs and ADRs issued and outstanding under the terms of the Deposit Agreement. 

  
 18 








 
In the event that, in determining the rights and obligations of parties hereto with respect to any Restricted ADSs, any conflict arises between (a) the terms of the Deposit Agreement (other
than this Section 2.14) and (b) the terms of (i) this Section 2.14 or (ii) the applicable Restricted ADR, the terms and conditions set forth in this Section 2.14 and of the Restricted ADR shall be controlling and shall
govern the rights and obligations of the parties to the Deposit Agreement pertaining to the deposited Restricted Shares, the Restricted ADSs and Restricted ADRs. 

If the Restricted ADRs, the Restricted ADSs and the Restricted Shares cease to be Restricted Securities, the Depositary, upon receipt of
(x) an opinion of counsel reasonably satisfactory to the Depositary setting forth, inter alia, that the Restricted ADRs, the Restricted ADSs and the Restricted Shares are not as of such time Restricted Securities, and
(y) instructions from the Company to remove the restrictions applicable to the Restricted ADRs, the Restricted ADSs and the Restricted Shares, shall (i) eliminate the distinctions and separations that may have been established between the
applicable Restricted Shares held on deposit under this Section 2.14 and the other Shares held on deposit under the terms of the Deposit Agreement that are not Restricted Shares, (ii) treat the newly unrestricted ADRs and ADSs on the same
terms as, and fully fungible with, the other ADRs and ADSs issued and outstanding under the terms of the Deposit Agreement that are not Restricted ADRs or Restricted ADSs, and (iii) take all actions necessary to remove any distinctions,
limitations and restrictions previously existing under this Section 2.14 between the applicable Restricted ADRs and Restricted ADSs, respectively, on the one hand, and the other ADRs and ADSs that are not Restricted ADRs or Restricted ADSs,
respectively, on the other hand, including, without limitation, by making the newly-unrestricted ADSs eligible for Pre-Release Transactions and for inclusion in the applicable book-entry settlement systems. 

ARTICLE III 
 CERTAIN
OBLIGATIONS OF HOLDERS 
 AND BENEFICIAL OWNERS OF ADSs 

Section 3.1 Proofs, Certificates and Other Information. Any person presenting Shares for deposit, any Holder and any
Beneficial Owner may be required, and every Holder and Beneficial Owner agrees, from time to time to provide to the Depositary and the Custodian such proof of citizenship or residence, taxpayer status, payment of all applicable taxes or other
governmental charges, exchange control approval, legal or beneficial ownership of ADSs and Deposited Property, compliance with applicable laws, the terms of the Deposit Agreement or the ADR(s) evidencing the ADSs and the provisions of, or governing,
the Deposited Property, to execute such certifications and to make such representations and warranties, and to provide such other information and documentation (or, in the case of Shares in registered form presented for deposit, such information
relating to the registration on the books of the Company) as the Depositary or the Custodian may deem necessary or proper or as the Company may reasonably require by written request to the Depositary consistent with its obligations under the Deposit
Agreement and the applicable ADR(s). The Depositary and the Registrar, as applicable, may, and at the reasonable request of the Company, shall, to the extent practicable, withhold the execution or delivery or registration of transfer of any ADR or
ADS or the distribution or sale of any dividend or distribution of rights or of the proceeds thereof or, to the extent not limited by 

  
 19 








 
the terms of Section 7.8, the delivery of any Deposited Property until such proof or other information is filed or such certifications are executed, or such representations and warranties
are made, or such other documentation or information provided, in each case to the Depositary’s, the Registrar’s and the Company’s satisfaction. The Depositary shall provide the Company, in a timely manner, with copies or originals if
necessary and appropriate of (i) any such proofs of citizenship or residence, taxpayer status, or exchange control approval or copies of written representations and warranties which it receives from Holders and Beneficial Owners, and
(ii) any other information or documents which the Company may reasonably request and which the Depositary shall request and receive from any Holder or Beneficial Owner or any person presenting Shares for deposit or ADSs for cancellation,
transfer or withdrawal. Nothing herein shall obligate the Depositary to (i) obtain any information for the Company if not provided by the Holders or Beneficial Owners, or (ii) verify or vouch for the accuracy of the information so provided
by the Holders or Beneficial Owners. 
 Section 3.2 Liability for Taxes and Other Charges. Any tax or other
governmental charge payable by the Custodian or by the Depositary with respect to any Deposited Property, ADSs or ADRs shall be payable by the Holders and Beneficial Owners to the Depositary. The Company, the Custodian and/or the Depositary may
withhold or deduct from any distributions made in respect of Deposited Property, and may sell for the account of a Holder and/or Beneficial Owner any or all of the Deposited Property and apply such distributions and sale proceeds in payment of, any
taxes (including applicable interest and penalties) or charges that are or may be payable by Holders or Beneficial Owners in respect of the ADSs, Deposited Property and ADRs, the Holder and the Beneficial Owner remaining liable for any deficiency.
The Custodian may refuse the deposit of Shares and the Depositary may refuse to issue ADSs, to deliver ADRs, register the transfer of ADSs, register the split-up or combination of ADRs and (subject to
Section 7.8) the withdrawal of Deposited Property until payment in full of such tax, charge, penalty or interest is received. Every Holder and Beneficial Owner agrees to indemnify the Depositary, the Company, the Custodian, and any of their
agents, officers, employees and Affiliates for, and to hold each of them harmless from, any claims with respect to taxes (including applicable interest and penalties thereon) arising from any tax benefit obtained for such Holder and/or Beneficial
Owner. 
 Section 3.3 Representations and Warranties on Deposit of Shares. Each person depositing Shares under the
Deposit Agreement shall be deemed thereby to represent and warrant that (i) such Shares and the certificates therefor are duly authorized, validly issued, fully paid, non-assessable and legally obtained
by such person, (ii) all preemptive (and similar) rights, if any, with respect to such Shares have been validly waived or exercised, (iii) the person making such deposit is duly authorized so to do, (iv) the Shares presented for
deposit are free and clear of any lien, encumbrance, security interest, charge, mortgage or adverse claim, (v) the Shares presented for deposit are not, and the ADSs issuable upon such deposit will not be, Restricted Securities (except as
contemplated in Section 2.14), (vi) the Shares presented for deposit have not been stripped of any rights or entitlements and (vii) the deposit of the Shares do not violate any provisions of Belgian law. Such representations and
warranties shall survive the deposit and withdrawal of Shares, the issuance and cancellation of ADSs in respect thereof and the transfer of such ADSs. If any such representations or warranties are false in any way, the Company and the Depositary
shall be authorized, at the cost and expense of the person depositing Shares, to take any and all actions necessary to correct the consequences thereof. 

  
 20 








 Section 3.4 Compliance with Information Requests. Notwithstanding any other
provision of the Deposit Agreement or any ADR(s), each Holder and Beneficial Owner agrees to comply with requests from the Company pursuant to applicable law, the rules and requirements of any stock exchange on which the Shares or ADSs are, or will
be, registered, traded or listed or the Articles of Association of the Company, which are made to provide information, inter alia, as to the capacity in which such Holder or Beneficial Owner owns ADSs (and Shares as the case may be) and
regarding the identity of any other person(s) interested in such ADSs and the nature of such interest and various other matters, whether or not they are Holders and/or Beneficial Owners at the time of such request. The Depositary agrees to use its
reasonable efforts to forward, upon the request of the Company and at the Company’s expense, any such request from the Company to the Holders and to forward to the Company, as promptly as practicable, any such responses to such requests
received by the Depositary. 
 Section 3.5 Ownership Restrictions. Subject to applicable law, notwithstanding any other
provision in the Deposit Agreement or any ADR, the Company may restrict transfers of the Shares where such transfer might result in ownership of Shares exceeding limits imposed by applicable law or the Articles of Association of the Company. The
Company may also restrict, in such manner as it deems appropriate, transfers of the ADSs where such transfer may result in the total number of Shares represented by the ADSs owned by a single Holder or Beneficial Owner to exceed any such limits. The
Company may, in its sole discretion but subject to applicable law, instruct the Depositary to take action with respect to the ownership interest of any Holder or Beneficial Owner in excess of the limits set forth in the preceding sentence,
including, but not limited to, the imposition of restrictions on the transfer of ADSs, the removal or limitation of voting rights or mandatory sale or disposition on behalf of a Holder or Beneficial Owner of the Shares represented by the ADSs held
by such Holder or Beneficial Owner in excess of such limitations, if and to the extent such disposition is permitted by applicable law and (if required) the Articles of Association of the Company. Nothing herein shall be interpreted as obligating
the Depositary or the Company to ensure compliance with the ownership restrictions described in this Section 3.5. 
 Section 3.6
Reporting Obligations and Regulatory Approvals. Applicable laws and regulations may require holders and beneficial owners of Shares, including the Holders and Beneficial Owners of ADSs, to satisfy reporting requirements and obtain
regulatory approvals in certain circumstances. Holders and Beneficial Owners of ADSs are solely responsible for determining and complying with such reporting requirements and obtaining such approvals. Each Holder and each Beneficial Owner hereby
agrees to make such determination, file such reports, and obtain such approvals to the extent and in the form required by applicable laws and regulations as in effect from time to time. Neither the Depositary, the Custodian, the Company or any of
their respective agents or affiliates shall be required to take any actions whatsoever on behalf of Holders or Beneficial Owners to determine or satisfy such reporting requirements or obtain such regulatory approvals under applicable laws and
regulations. 

  
 21 








 Section 3.7 Disclosure of Interest. The Company has advised the Depositary and the
parties to the Deposit Agreement acknowledge that, Belgian law, as in effect on the date of the Deposit Agreement, provides that: 
 (a) Any
person or legal entity, which owns or acquires securities of the Company granting voting rights (including Shares) (either directly or by ownership of ADSs or both), whether representing the share capital or not, must disclose to the Company and to
the Belgian Financial Services and Markets Authority (FSMA) the number of securities that such person or legal entity owns, alone or jointly with one or several other persons or legal entities, when the voting rights attached to such securities
amount to 5 percent or more of the total of the voting rights existing when the situation triggering the disclosure obligation occurs. Such person or legal entity must make the same disclosure in the event of a transfer or of an additional
acquisition of such securities when, after such transaction, the voting rights attached to securities owned by such person or legal entity amount to 5 percent, 10 percent, and so on by blocks of 5 percent of the total of the voting rights existing
when the situation triggering the disclosure obligation occurs, or when the voting rights attached to securities owned by such person or legal entity fall below one of the thresholds referred to in this Section 3.7(a); 

(b) Any person or legal entity which acquires or transfers, alone or jointly, the direct or indirect control of a corporation or other legal
entity which owns 5 percent at least of the voting rights of the Company (either directly or by ownership of ADSs or both) must disclose such acquisition or transfer to the Company and to the FSMA; 

(c) A disclosure described above is also required when, as a result of events changing the breakdown of voting rights, the percentage of the
voting rights attached to the voting securities reaches, exceeds or falls below the thresholds referred to in Section 3.7(a) above, even when no acquisition or disposal of securities has occurred (e.g., as a result of a capital increase or a
capital decrease of the Company). A disclosure is equally required when persons or legal entities enter into, modify or terminate an agreement of action in concert, when as result thereof, the percentage of the voting rights subject to the action in
concert or the percentage of the voting rights of one of the parties to the agreement of action in concert reaches, exceeds or falls below the thresholds referred to in Section 3.7(a) above; 

(d) Disclosure statements referred to in this Section 3.7 must be addressed to the Belgian Financial Services and Markets Authority (whose
offices are currently located Rue du Congrès 12-14, 1000 Brussels, Belgium) and to the board of directors of the Company at the latest the fourth trading day in Euronext Brussels following the day on which (i) the person or legal entity
is aware of the acquisition or the disposal or the possibility of exercising voting rights, or, having regard to the circumstances, should have been aware of it, regardless of the date on which the acquisition, disposal or possibility of exercising
voting rights takes effect, (ii) the person or legal entity is aware of the event changing the break down of voting rights, (iii) an agreement of action in concert is entered into, modified or terminated, or (iv) for securities
acquired by succession, the succession is accepted by the heirs, as the case may be, under the benefit of inventory (as such term is defined under Belgian law); 

  
 22 








 (e) Unless otherwise provided by legal provisions in force, no one will be allowed to vote at a
meeting of the holders of the Shares a number of securities greater than the number validly disclosed, to the extent required, at the latest twenty (20) days before such meeting, in compliance with legal provisions in force and with the
Articles of Association; and 
 (f) The disclosure requirements and limitations set out in Sections 3.7 (a) to (e) above are
applicable to any Holder of ADSs and/or Beneficial Owner by reference to the number of both ADSs and Shares (that are not Deposited Securities) held by such Holder and/or beneficially owned by such Beneficial Owner. This Section 3.7 is a
summary of the applicable provisions of Belgian law, as in effect as of the date of the Deposit Agreement, regarding disclosure of interests in the Company and shall not limit the obligations of Holders and Beneficial Owners to comply with all
relevant provisions of Belgian law, as applicable from time to time. Each Holder and Beneficial Owner shall be deemed to have authorized the Depositary and the Custodian to comply with any request from the Company or any competent authority to
disclose any information about any interest or any transaction of such Holder or Beneficial Owner in ADSs or Shares or Deposited Securities. 

  
 23 








 ARTICLE IV 

THE DEPOSITED SECURITIES 

Section 4.1 Cash Distributions. Whenever the Company intends to make a distribution of a cash dividend or other cash
distribution in respect of any Deposited Securities, the Company shall give notice thereof to the Depositary at least twenty (20) days prior to the proposed distribution specifying, inter alia, the record date applicable
for determining the holders of Deposited Securities entitled to receive such distribution. Upon the timely receipt of such notice, the Depositary shall establish an ADS Record Date upon the terms described in Section 4.9. Upon receipt of
confirmation from the Custodian of the receipt of any cash dividend or other cash distribution on any Deposited Securities, or upon receipt of proceeds from the sale of any Deposited Property held in respect of the ADSs under the terms hereof, the
Depositary will (i) if at the time of receipt thereof any amounts received in a Foreign Currency can, in the judgment of the Depositary (pursuant to Section 4.8), be converted on a practicable basis into Dollars transferable to the United
States, promptly convert or cause to be converted such cash dividend, distribution or proceeds into Dollars (on the terms described in Section 4.8), (ii) if applicable and unless previously established, establish the ADS Record Date upon
the terms described in Section 4.9, and (iii) distribute promptly the amount thus received (net of (a) the applicable fees and charges of, and expenses incurred by, the Depositary and (b) taxes required to be withheld as a result
of the distribution) to the Holders entitled thereto as of the ADS Record Date in proportion to the number of ADSs held as of the ADS Record Date. The Depositary shall distribute only such amount, however, as can be distributed without attributing
to any Holder a fraction of one cent, and any balance not so distributed shall be held by the Depositary (without liability for interest thereon) and shall be added to and become part of the next sum received by the Depositary for distribution to
Holders of ADSs outstanding at the time of the next distribution. If the Company, the Custodian or the Depositary is required to withhold and does withhold from any cash dividend or other cash distribution in respect of any Deposited Securities, or
from any cash proceeds from the sales of Deposited Property, an amount on account of taxes, duties or other governmental charges, the amount distributed to Holders on the ADSs shall be reduced accordingly. Such withheld amounts shall be forwarded by
the Company, the Custodian or the Depositary to the relevant governmental authority. Evidence of payment thereof by the Company shall be forwarded by the Company to the Depositary upon request. The Depositary will hold any cash amounts it is unable
to distribute in a non-interest bearing account for the benefit of the applicable Holders and Beneficial Owners of ADSs until the distribution can be effected or the funds that the Depositary holds must be escheated as unclaimed property in
accordance with the laws of the relevant states of the United States. Notwithstanding anything contained in the Deposit Agreement to the contrary, in the event the Company fails to give the Depositary timely notice of the proposed distribution
provided for in this Section 4.1, the Depositary agrees to use commercially reasonable efforts to perform the actions contemplated in this Section 4.1, and the Company, the Holders and the Beneficial Owners acknowledge that the Depositary
shall have no liability for the Depositary’s failure to perform the actions contemplated in this Section 4.1 where such notice has not been so timely given, other than its failure to use commercially reasonable efforts, as provided herein.


  
 24 








 Section 4.2 Distribution in Shares. Whenever the Company intends to
make a distribution that consists of a dividend in, or free distribution of, Shares, the Company shall give notice thereof to the Depositary at least twenty (20) days prior to the proposed distribution, specifying, inter
alia, the record date applicable to holders of Deposited Securities entitled to receive such distribution. Upon the timely receipt of such notice from the Company, the Depositary shall establish the ADS Record Date upon the terms
described in Section 4.9. Upon receipt of confirmation from the Custodian of the receipt of the Shares so distributed by the Company, the Depositary shall either (i) subject to Section 5.9, distribute to the Holders as of the ADS
Record Date in proportion to the number of ADSs held as of the ADS Record Date, additional ADSs, which represent in the aggregate the number of Shares received as such dividend, or free distribution, subject to the other terms of the Deposit
Agreement (including, without limitation, (a) the applicable fees and charges of, and expenses incurred by, the Depositary and (b) taxes), or (ii) if additional ADSs are not so distributed, take all actions necessary so that each ADS
issued and outstanding after the ADS Record Date shall, to the extent permissible by law, thenceforth also represent rights and interests in the additional integral number of Shares distributed upon the Deposited Securities represented thereby (net
of (a) the applicable fees and charges of, and expenses incurred by, the Depositary and (b) taxes). In lieu of delivering fractional ADSs, the Depositary shall sell the number of Shares or ADSs, as the case may be, represented by the
aggregate of such fractions and distribute the net proceeds upon the terms described in Section 4.1. In the event that the Depositary determines that any distribution in property (including Shares) is subject to any tax or other governmental
charges which the Depositary is obligated to withhold, or, if the Company in the fulfillment of its obligation under Section 5.7, has furnished an opinion of U.S. counsel determining that Shares must be registered under the Securities Act or
other laws in order to be distributed to Holders (and no such registration statement has been declared effective), the Depositary may, after consultation with the Company to the extent reasonably practicable, dispose of all or a portion of such
property (including Shares and rights to subscribe therefor) in such amounts and in such manner, including by public or private sale, as the Depositary deems necessary and practicable, and the Depositary shall distribute the net proceeds of any such
sale (after deduction of (a) taxes and (b) fees and charges of, and expenses incurred by, the Depositary) to Holders entitled thereto upon the terms described in Section 4.1. The Depositary shall hold and/or distribute any unsold
balance of such property in accordance with the provisions of the Deposit Agreement. Notwithstanding anything contained in the Deposit Agreement to the contrary, in the event the Company fails to give the Depositary timely notice of the proposed
distribution provided for in this Section 4.2, the Depositary agrees to use commercially reasonable efforts to perform the actions contemplated in this Section 4.2, and the Company, the Holders and the Beneficial Owners acknowledge that
the Depositary shall have no liability for the Depositary’s failure to perform the actions contemplated in this Section 4.2 where such notice has not been so timely given, other than its failure to use commercially reasonable efforts, as
provided herein. 
 Section 4.3 Elective Distributions in Cash or Shares. Whenever the Company intends to make a
distribution payable at the election of the holders of Deposited Securities in cash or in additional Shares, the Company shall give notice thereof to the Depositary at least forty-five (45) days prior to the proposed distribution specifying,
inter alia, the record date applicable to holders of Deposited Securities entitled to receive such elective distribution and whether or not it wishes such elective distribution to be made available to Holders of ADSs.


  
 25 








 
Upon the timely receipt of a notice indicating that the Company wishes such elective distribution to be made available to Holders of ADSs, the Depositary shall consult with the Company to
determine, and the Company shall assist the Depositary in its determination, whether it is lawful and reasonably practicable to make such elective distribution available to the Holders of ADSs. The Depositary shall make such elective distribution
available to Holders only if (i) the Company shall have timely requested that the elective distribution be made available to Holders, (ii) the Depositary shall have determined that such distribution is reasonably practicable and
(iii) the Depositary shall have received satisfactory documentation within the terms of Section 5.7. If the above conditions are not satisfied, the Depositary shall establish an ADS Record Date on the terms described in Section 4.9
and, to the extent permitted by law, distribute to the Holders, on the basis of the same determination as is made in the Kingdom of Belgium in respect of the Shares for which no election is made, either (X) cash upon the terms described in
Section 4.1 or (Y) additional ADSs representing such additional Shares upon the terms described in Section 4.2. If the above conditions are satisfied, the Depositary shall establish an ADS Record Date on the terms described in
Section 4.9 and establish procedures to enable Holders to elect the receipt of the proposed distribution in cash or in additional ADSs. The Company shall assist the Depositary in establishing such procedures to the extent necessary. If a Holder
elects to receive the proposed distribution (X) in cash, the distribution shall be made upon the terms described in Section 4.1, or (Y) in ADSs, the distribution shall be made upon the terms described in Section 4.2. Nothing
herein shall obligate the Depositary to make available to Holders a method to receive the elective distribution in Shares (rather than ADSs). There can be no assurance that Holders generally, or any Holder in particular, will be given the
opportunity to receive elective distributions on the same terms and conditions as the holders of Shares. Notwithstanding anything contained in the Deposit Agreement to the contrary, in the event the Company fails to give the Depositary timely notice
of the proposed distribution provided for in this Section 4.3, the Depositary agrees to use commercially reasonable efforts to perform the actions contemplated in this Section 4.3, and the Company, the Holders and the Beneficial Owners
acknowledge that the Depositary shall have no liability for the Depositary’s failure to perform the actions contemplated in this Section 4.3 where such notice has not been so timely given, other than its failure to use commercially
reasonable efforts, as provided herein. 
 Section 4.4 Distribution of Rights to Purchase Additional Shares in the Form of
ADSs. 
 (a) Offer to holders of the Deposited Securities. Whenever the Company intends to offer, distribute, or
cause to be offered or distributed to the holders of the Deposited Securities rights to subscribe for additional Shares, the Company shall give notice thereof to the Depositary at least forty-five (45) days prior to the proposed offer
specifying, inter alia, the record date applicable to holders of Deposited Securities entitled to receive such rights and whether or not it wishes such rights to be made available to Holders of ADSs. Upon the timely receipt of a
notice indicating that the Company wishes such rights to be made available to Holders of ADSs, the Depositary shall consult with the Company to determine, and the Company shall assist the Depositary in its determination, whether it is lawful and
reasonably practicable to make such rights available to the Holders. The Depositary shall make such rights available to Holders only if (i) the Company shall have timely requested that such rights be made available to Holders, (ii) the
Depositary shall have received satisfactory documentation within the terms of Section 5.7, 

  
 26 








 
and (iii) the Depositary shall have determined that such distribution of rights is reasonably practicable. In the event any of the conditions set forth above are not satisfied or if the
Company requests that the rights not be made available to Holders of ADSs, the Depositary shall proceed with the sale of the rights as contemplated in Section 4.4(b) below. In the event all conditions set forth above are satisfied, the
Depositary shall establish an ADS Record Date (upon the terms described in Section 4.9) and establish procedures to (x) distribute rights to purchase additional ADSs (by means of warrants or otherwise), (y) to enable the Holders to
exercise such rights (upon payment of the subscription price and of the applicable (a) fees and charges of, and expenses incurred by, the Depositary and (b) taxes), and (z) to deliver ADSs upon the valid exercise of such rights. The
Company shall assist the Depositary to the extent necessary in establishing such procedures. Nothing herein shall obligate the Depositary to make available to the Holders a method to exercise rights to subscribe for Shares (rather than ADSs). 

(b) Sale of Rights. If (i) the Company does not timely request the Depositary to make the rights available to
Holders or requests that the rights not be made available to Holders, (ii) the Depositary fails to receive satisfactory documentation within the terms of Section 5.7, or determines it is not reasonably practicable to make the rights
available to Holders, or (iii) any rights made available are not exercised and appear to be about to lapse, the Depositary shall determine whether it is lawful and reasonably practicable to sell such rights, in a riskless principal capacity, at
such place and upon such terms (including public or private sale) as it may deem practicable. The Company shall assist the Depositary to the extent necessary to determine such legality and practicability. The Depositary shall, upon such sale,
convert and distribute proceeds of such sale (net of applicable (a) fees and charges of, and expenses incurred by, the Depositary and (b) taxes) upon the terms set forth in Section 4.1. 

(c) Lapse of Rights. If the Depositary is unable to make any rights available to Holders upon the terms described
in Section 4.4(a) or to arrange for the sale of the rights upon the terms described in Section 4.4(b), the Depositary shall allow such rights to lapse. 

The Depositary shall not be responsible for (i) any failure to determine that it may be lawful or practicable to make such rights
available to Holders in general or any Holders in particular, (ii) any foreign exchange exposure or loss incurred in connection with such sale, or exercise, or (iii) the content of any materials forwarded to the Holders on behalf of the
Company in connection with the rights distribution. 
 Notwithstanding anything to the contrary in this Section 4.4, if registration
(under the Securities Act or any other applicable law) of the rights or the securities to which any rights relate may be required in order for the Company to offer such rights or such securities to Holders and to sell the securities represented by
such rights, the Depositary will not distribute such rights to the Holders (i) unless and until a registration statement under the Securities Act (or other applicable law) covering such offering is in effect or (ii) unless the Company
furnishes the Depositary opinion(s) of counsel for the Company in the United States and counsel to the Company in any other applicable country in which rights would be distributed, in each case reasonably satisfactory to the Depositary, to the
effect that the offering and sale of such securities to Holders and Beneficial Owners are exempt from, or do not require registration under, the provisions of the Securities Act or any other applicable laws. 

  
 27 








 In the event that the Company, the Depositary or the Custodian shall be required to withhold and
does withhold from any distribution of Deposited Property (including rights) an amount on account of taxes or other governmental charges, the amount distributed to the Holders of ADSs shall be reduced accordingly. In the event that the Depositary
reasonably determines that any distribution of Deposited Property (including Shares and rights to subscribe therefor) is subject to any tax or other governmental charges which the Depositary is obligated to withhold, the Depositary may dispose of
all or a portion of such Deposited Property (including Shares and rights to subscribe therefor) in such amounts and in such manner, including by public or private sale, as the Depositary deems necessary and practicable to pay any such taxes or
charges. 
 There can be no assurance that Holders generally, or any Holder in particular, will be given the opportunity to receive or
exercise rights on the same terms and conditions as the holders of Shares or be able to exercise such rights. Nothing herein shall obligate the Company to file any registration statement in respect of any rights or Shares or other securities to be
acquired upon the exercise of such rights. 
 Section 4.5 Distributions Other Than Cash, Shares or Rights to Purchase Shares.

 (a) Whenever the Company intends to distribute to the holders of Deposited Securities property other than cash, Shares or
rights to purchase additional Shares, the Company shall give timely notice thereof to the Depositary and shall indicate whether or not it wishes such distribution to be made to Holders of ADSs. Upon receipt of a notice indicating that the Company
wishes such distribution be made to Holders of ADSs, the Depositary shall consult with the Company, and the Company shall assist the Depositary, to determine whether such distribution to Holders is lawful and reasonably practicable. The Depositary
shall not make such distribution unless (i) the Company shall have requested the Depositary to make such distribution to Holders, (ii) the Depositary shall have received satisfactory documentation within the terms of Section 5.7, and
(iii) the Depositary shall have determined that such distribution is reasonably practicable. 
 (b) Upon receipt of satisfactory
documentation and the request of the Company to distribute property to Holders of ADSs and after making the requisite determinations set forth in (a) above, the Depositary shall distribute the property so received to the Holders of record, as
of the ADS Record Date, in proportion to the number of ADSs held by them respectively and in such manner as the Depositary may deem practicable for accomplishing such distribution (i) upon receipt of payment or net of the applicable fees and
charges of, and expenses incurred by, the Depositary, and (ii) net of any taxes required to be withheld. The Depositary may dispose of all or a portion of the property so distributed and deposited, in such amounts and in such manner (including
public or private sale) as the Depositary may deem practicable or necessary to satisfy any taxes (including applicable interest and penalties) or other governmental charges applicable to the distribution. 

(c) If (i) the Company does not request the Depositary to make such distribution to Holders or requests not to make such
distribution to Holders, (ii) the Depositary does not receive satisfactory documentation within the terms of Section 5.7, or (iii) the Depositary determines that all or a portion of such distribution is not reasonably practicable, the
Depositary shall sell or 

  
 28 








 
cause such property to be sold in a public or private sale, at such place or places and upon such terms as it may deem practicable and shall (i) cause the proceeds of such sale, if any, to
be converted into Dollars and (ii) distribute the proceeds of such conversion received by the Depositary (net of applicable (a) fees and charges of, and expenses incurred by, the Depositary and (b) taxes) to the Holders as of the ADS
Record Date upon the terms of Section 4.1. If the Depositary is unable to sell such property, the Depositary may dispose of such property for the account of the Holders in any way it deems reasonably practicable under the circumstances. 

(d) Neither the Depositary nor the Company shall be responsible for (i) any failure to determine whether it is lawful or
practicable to make the property described in this Section 4.5 available to Holders in general or any Holders in particular, nor (ii) any loss incurred in connection with the sale or disposal of such property. 

Section 4.6 [RESERVED].  

Section 4.7 Redemption. If the Company intends to exercise any right of redemption (by way of shareholders resolution or
otherwise) in respect of any of the Deposited Securities (where such Deposited Securities provide the Company with a right of redemption), the Company shall give notice thereof to the Depositary at least thirty (30) days prior to the intended
date of redemption which notice shall set forth the particulars of the proposed redemption. Upon timely receipt of (i) such notice and (ii) satisfactory documentation given by the Company to the Depositary within the terms of
Section 5.7, and only if, after consultation between the Depositary and the Company, the Depositary shall have determined that such proposed redemption is practicable, the Depositary shall provide to each Holder a notice setting forth the
intended exercise by the Company of the redemption rights and any other particulars set forth in the Company’s notice to the Depositary. The Depositary shall instruct the Custodian to present to the Company the Deposited Securities in respect
of which redemption rights are being exercised against payment of the applicable redemption price. Upon receipt of confirmation from the Custodian that the redemption has taken place and that funds representing the redemption price have been
received, the Depositary shall convert, transfer, and distribute the proceeds (net of applicable (a) fees and charges of, and the expenses incurred by, the Depositary, and (b) taxes), retire ADSs and cancel ADRs, if applicable, upon
delivery of such ADSs by Holders thereof and the terms set forth in Sections 4.1 and 6.2. If less than all outstanding Deposited Securities are redeemed, the ADSs to be retired will be selected by lot or on a pro rata basis, as may be determined by
the Depositary after consultation with the Company. The redemption price per ADS shall be the dollar equivalent of the per share amount received by the Depositary (adjusted to reflect the ADS(s)-to-Share(s) ratio) upon the redemption of the
Deposited Securities represented by ADSs (subject to the terms of Section 4.8 and the applicable fees and charges of, and expenses incurred by, the Depositary, and taxes) multiplied by the number of Deposited Securities represented by each ADS
redeemed. Notwithstanding anything contained in the Deposit Agreement to the contrary, in the event the Company fails to give the Depositary timely notice of the proposed redemption provided for in this Section 4.7, the Depositary agrees to use
commercially reasonable efforts to perform the actions contemplated in this Section 4.7, and the Company, the Holders and the Beneficial Owners acknowledge that the Depositary shall have no liability for the Depositary’s failure to perform
the actions contemplated in this Section 4.7 where such notice has not been so timely given, other than its failure to use commercially reasonable efforts, as provided herein.

 Section 4.8 Conversion of Foreign Currency. Whenever the Depositary or the
Custodian shall receive Foreign Currency, by way of dividends or other distributions or the net proceeds from the sale of Deposited Property, which in the judgment of the Depositary can at such time be converted on a practicable basis, by sale or in
any other manner that it may determine in accordance with applicable law, into Dollars transferable to the United States and distributable to the Holders entitled thereto, the Depositary shall convert or cause to be converted, by sale or in any
other manner that it may determine, such Foreign Currency into Dollars, and shall distribute such Dollars (net of any applicable fees, any reasonable and customary expenses incurred in such conversion and any expenses incurred on behalf of the
Holders in complying with currency exchange control or other governmental requirements) in accordance with the terms of the applicable sections of the Deposit Agreement. If the Depositary shall have distributed warrants or other instruments that
entitle the holders thereof to such Dollars, the Depositary shall distribute such Dollars to the holders of such warrants and/or instruments upon surrender thereof for cancellation, in either case without liability for interest thereon. Such
distribution may be made upon an averaged or other practicable basis without regard to any distinctions among Holders on account of any application of exchange restrictions or otherwise. 

If such conversion or distribution generally or with regard to a particular Holder can be effected only with the approval or license of any
government or agency thereof, the Depositary shall have authority to file such application for approval or license, if any, as it may deem desirable. In no event, however, shall the Depositary be obligated to make such a filing. 

If at any time the Depositary shall determine that in its judgment the conversion of any Foreign Currency and the transfer and distribution of
proceeds of such conversion received by the Depositary is not practicable or lawful, or if any approval or license of any governmental authority or agency thereof that is required for such conversion, transfer and distribution is denied or, in the
opinion of the Depositary, not obtainable at a reasonable cost or within a reasonable period, the Depositary may, in its reasonable discretion, (i) make such conversion and distribution in Dollars to the Holders for whom such conversion,
transfer and distribution is lawful and practicable, (ii) distribute the Foreign Currency (or an appropriate document evidencing the right to receive such Foreign Currency) to Holders for whom this is lawful and practicable, or (iii) hold
(or cause the Custodian to hold) such Foreign Currency (without liability for interest thereon) for the respective accounts of the Holders entitled to receive the same. 

Section 4.9 Fixing of ADS Record Date. Whenever the Depositary shall receive notice of the fixing of a record date by the
Company for the determination of holders of Deposited Securities entitled to receive any distribution (whether in cash, Shares, rights, or other distribution), or whenever for any reason the Depositary causes a change in the number of Shares that
are represented by each ADS, or whenever the Depositary shall receive notice of any meeting of, or solicitation of consents or proxies of, holders of Shares or other Deposited Securities, or whenever the Depositary shall find it necessary or
convenient in connection with the giving of any notice, solicitation of any consent or any other matter, the Depositary, after 

  
 30 








 
consultation with the Company to the extent reasonably practicable, shall fix a record date (the “ADS Record Date”) for the determination of the Holders of ADS(s) who shall be
entitled to receive such distribution, to give instructions for the exercise of voting rights at any such meeting, to give or withhold such consent, to receive such notice or solicitation or to otherwise take action, or to exercise the rights of
Holders with respect to such changed number of Shares represented by each ADS. The Depositary shall make reasonable efforts to establish the ADS Record Date as closely as possible to the applicable record date for the Deposited Securities (if any)
set by the Company in the Kingdom of Belgium and shall not announce the establishment of any ADS Record Date prior to the relevant corporate action having been made public by the Company (if such corporate action affects the Deposited Securities).
Subject to applicable law and the provisions of Section 4.1 through 4.8 and to the other terms and conditions of the Deposit Agreement, only the Holders of ADSs at the close of business in New York on such ADS Record Date shall be entitled to
receive such distribution, to give such voting instructions, to receive such notice or solicitation, or otherwise take action. For the ADS Record Date in respect of a shareholders meeting of the Company, such date shall be determined by the
Depositary and the Company jointly, it being understood that such ADS Record Date shall not be established earlier than 30 days prior to the relevant shareholders meeting. 

Section 4.10 Voting of Deposited Securities. As soon as practicable after receipt of notice of any meeting at which the
holders of Deposited Securities are entitled to vote, or of solicitation of consents or proxies from holders of Deposited Securities, the Depositary shall fix the ADS Record Date in respect of such meeting or solicitation of consent or proxy in
accordance with Section 4.9. The Depositary shall, as soon as practicable after receipt of notice of any meeting at which the holders of Deposited Securities are entitled to vote, or of solicitation of consents or proxies from holders of
Deposited Securities, if requested by the Company in writing in a timely manner, at the Company’s expense and provided no U.S. legal prohibitions exist, distribute to Holders as of the ADS Record Date: (a) such notice of meeting or
solicitation of consent or proxy, (b) a statement that the Holders at the close of business on the ADS Record Date and, if so required by the Company, who also hold the ADSs as of the applicable share record date, will be entitled, subject to
any applicable law, the provisions of the Deposit Agreement, the Articles of Association of the Company and the provisions of or governing the Deposited Securities (which provisions, if any, shall be summarized in pertinent part by the Company), to
instruct the Depositary as to the exercise of the voting rights, if any, pertaining to the Deposited Securities represented by such Holder’s ADSs, and (c) a brief statement as to the manner and timing (such timing to be determined after
consultation with the Company) in which such voting instructions may be given, including the following express indications: (x) that no voting rights will be exercised by the Depositary if the Depositary does not receive voting instructions
timely from a Holder; and (y) that the Depositary will deem a Holder (unless otherwise specified in the notice distributed to the Holders) to have instructed the Depositary to vote in favor of the items set forth in such voting instructions if
the Depositary has timely received the voting instructions from such Holder but if such Holder has failed to specify the manner in which the Depositary is to vote the Deposited Securities represented by such Holder’s ADSs. 

Notwithstanding anything contained in the Deposit Agreement or any ADR, the Depositary may, to the extent not prohibited by law or
regulations, or by the requirements of the 

  
 31 








 
stock exchange on which the ADSs are listed, and after consultation with the Company to the extent reasonably practicable, in lieu of distribution of the materials provided to the Depositary in
connection with any meeting of, or solicitation of consents or proxies from, holders of Deposited Securities, distribute to the Holders a notice that provides Holders with, or otherwise publicizes to Holders, instructions on how to retrieve such
materials or receive such materials upon request (i.e., by reference to a website containing the materials for retrieval or a contact for requesting copies of the materials); provided, that, upon request of any Holder, the Depositary timely
distributes to such Holder the materials provided to the Depositary in connection with any meeting of the holders of the Shares. 
 Voting
instructions may be given only in respect of a number of ADSs representing an integral number of Deposited Securities. Upon the timely receipt from a Holder of ADSs as of the ADS Record Date (and, if so required by the Company, who also hold the
ADSs as of the applicable share record date) of voting instructions in the manner specified by the Depositary, the Depositary shall endeavor, insofar as practicable and permitted under applicable law, the provisions of the Deposit Agreement,
Articles of Association of the Company and the provisions of the Deposited Securities, to vote, or cause the Custodian to vote, the Deposited Securities (in person or by proxy) represented by such Holder’s ADSs in accordance with such voting
instructions. The Depositary agrees not to vote, cause to be voted or attempt to exercise the right to vote that attaches to any Deposited Securities, other than in accordance with valid voting instructions given or deemed given in compliance with
this Section. 
 Deposited Securities represented by ADSs for which no timely voting instructions are received by the Depositary from the
Holder shall not be voted (except as otherwise contemplated herein). Neither the Depositary nor the Custodian shall under any circumstances exercise any discretion as to voting and neither the Depositary nor the Custodian shall vote, attempt to
exercise the right to vote, or in any way make use of, for purposes of establishing a quorum or otherwise, the Deposited Securities represented by ADSs, except pursuant to and in accordance with the voting instructions timely received from Holders
or as otherwise contemplated herein. If the Depositary timely receives voting instructions from a Holder which fail to specify the manner in which the Depositary is to vote the Deposited Securities represented by such Holder’s ADSs, the
Depositary will deem such Holder (unless otherwise specified in the notice distributed to Holders) to have instructed the Depositary to vote in favor of the items set forth in such voting instructions. 

The right of any Holder to give instructions to the Depositary as to the exercise of voting rights or the right of any Holder to withdraw
Deposited Securities in person or by proxy may be limited if such Holder fails to comply with the requirements described in Sections 3.4, 3.5, 3.6 and 3.7. 

Notwithstanding anything else contained in the Deposit Agreement or any ADR, the Depositary shall not have any obligation to take any action
with respect to any meeting, or solicitation of consents or proxies, of holders of Deposited Securities if the taking of such action would violate U.S. laws. The Company agrees to take any and all actions reasonably necessary to enable Holders and
Beneficial Owners to exercise the voting rights accruing to the Deposited Securities and to deliver to the Depositary an opinion of U.S. counsel addressing any actions requested to be taken if so reasonably requested by the Depositary. 

  
 32 








 There can be no assurance that Holders generally or any Holder in particular will receive the
notice described above with sufficient time to enable the Holder to return voting instructions to the Depositary, or otherwise take action, in a timely manner. 

The Depositary agrees, upon the request of Company, to provide to the Company copies of the voting instructions it receives (in the case of
voting instructions received from Holders by any electronic means, a tabulation of such voting instructions) as promptly as practicable, and at the latest six (6) business days prior to any upcoming meeting date, upon receipt thereof. 

Holders who have delivered voting instructions agree that such voting instruction may, at the request of the Company, be disclosed by the
Company, for purposes of compliance with Belgian law, in connection with any meeting of the holders of the Shares, whether prior, during or after such meeting. 

Notwithstanding anything else contained in the Deposit Agreement or any Receipt to the contrary, and to the extent not prohibited by law or
regulations, the Depositary and the Company may, by agreement between them, with notice to the Holders, modify, amend or adopt additional voting procedures from time to time as they determine may be necessary or appropriate (subject, in each case,
to the terms of Sections 6.1 and 7.8). 
 Section 4.11 Changes Affecting Deposited Securities. Upon any split-up, cancellation, consolidation or any other reclassification of Deposited Securities, or upon any recapitalization, reorganization, merger, consolidation or sale of assets affecting the Company or to which it
is a party, any property which shall be received by the Depositary or the Custodian in exchange for, or in conversion of, or replacement of, or otherwise in respect of, such Deposited Securities shall, to the extent permitted by law, be treated as
new Deposited Property under the Deposit Agreement, and the ADSs shall, subject to the provisions of the Deposit Agreement, any ADR(s) evidencing such ADSs and applicable law, represent the right to receive such additional or replacement Deposited
Property. In giving effect to such, split-up, cancellation, consolidation or other reclassification of Deposited Securities, recapitalization, reorganization, merger, consolidation or sale of assets, the Depositary may, with the Company’s
approval, and shall, if the Company shall so request, subject to the terms of the Deposit Agreement and receipt of an opinion of counsel to the Company reasonably satisfactory to the Depositary that such actions are not in violation of any
applicable laws or regulations, (i) issue and deliver additional ADSs as in the case of a stock dividend on the Shares, (ii) amend the Deposit Agreement and the applicable ADRs, (iii) amend the applicable Registration Statement(s) on
Form F-6 as filed with the Commission in respect of the ADSs, (iv) call for the surrender of outstanding ADRs to be exchanged for new ADRs, and (v) take such other actions as are appropriate to reflect the transaction with respect to the
ADSs. The Company agrees to, jointly with the Depositary, amend the Registration Statement on Form F-6 as filed with the Commission to permit the issuance of such new form of ADRs. Notwithstanding the foregoing, in the event that any Deposited
Property so received may not be lawfully distributed to some or all Holders, the  

  
 33 








 
Depositary may, with the Company’s approval, and shall, if the Company requests, subject to receipt of an opinion of Company’s counsel reasonably satisfactory to the Depositary that
such action is not in violation of any applicable laws or regulations, sell such Deposited Property at public or private sale, at such place or places and upon such terms as it may deem proper and may allocate the net proceeds of such sales (net of
(a) fees and charges of, and expenses incurred by, the Depositary and (b) applicable taxes) for the account of the Holders otherwise entitled to such Deposited Property upon an averaged or other practicable basis without regard to any
distinctions among such Holders and distribute the net proceeds so allocated to the extent practicable as in the case of a distribution received in cash pursuant to Section 4.1. The Depositary shall not be responsible for (i) any failure
to determine that it may be lawful or practicable to make such Deposited Property available to Holders in general or to any Holder in particular, (ii) any foreign exchange exposure or loss incurred in connection with such sale, or
(iii) any liability to the purchaser of such Deposited Property. 
 Section 4.12 Available Information. The Company
is subject to the periodic reporting requirements of the Exchange Act and, accordingly, is required to file or submit certain reports with the Commission. These reports can be retrieved from the Commission’s website (www.sec.gov) and can
be inspected and copied at the public reference facilities maintained by the Commission located (as of the date of the Deposit Agreement) at 100 F Street, N.E., Washington D.C. 20549. 

Section 4.13 Reports. The Depositary shall make available for inspection by Holders at its Principal Office, as promptly as
practicable after receipt thereof, any reports and communications, including any proxy soliciting materials, received from the Company which are both (a) received by the Depositary, the Custodian, or the nominee of either of them as the holder
of the Deposited Property and (b) made generally available to the holders of such Deposited Property by the Company. The Depositary shall also provide or make available to Holders copies of such reports when furnished by the Company pursuant to
Section 5.6. 
 Section 4.14 List of Holders. Promptly upon written request by the Company, the Depositary shall furnish
to it a list, as of a recent date, of the names, addresses and holdings of ADSs of all Holders. 
 Section 4.15
Taxation. The Depositary will, and will instruct the Custodian to, forward to the Company or its agents such information from its records as the Company may reasonably request to enable the Company or its agents to file the
necessary tax reports with governmental authorities or agencies. The Depositary, the Custodian or the Company and its agents may file such reports as are necessary to reduce or eliminate applicable taxes on dividends and on other distributions in
respect of Deposited Property under applicable tax treaties or laws for the Holders and Beneficial Owners. In accordance with instructions from the Company and to the extent practicable, the Depositary or the Custodian will take reasonable
administrative actions to obtain tax refunds, reduced withholding of tax at source on dividends and other benefits under applicable tax treaties or laws with respect to dividends and other distributions on the Deposited Property. As a condition to
receiving such benefits, Holders and Beneficial Owners of ADSs may be required from time to time, and in a timely manner, to file such proof of taxpayer status, residence and beneficial ownership (as applicable), to execute such


  
 34 








 
certificates and to make such representations and warranties, or to provide any other information or documents, as the Depositary or the Custodian may deem necessary or proper to fulfill the
Depositary’s or the Custodian’s obligations under applicable law. The Depositary and the Company shall have no obligation or liability to any person if any Holder or Beneficial Owner fails to provide such information or if such information
does not reach the relevant tax authorities in time for any Holder or Beneficial Owner to obtain the benefits of any tax treatment. The Holders and Beneficial Owners shall indemnify the Depositary, the Company, the Custodian and any of their
respective directors, employees, agents and Affiliates against, and hold each of them harmless from, any claims by any governmental authority with respect to taxes, additions to tax, penalties or interest arising out of any refund of taxes, reduced
rate of withholding at source or other tax benefit obtained. 
 If the Company (or any of its agents) withholds from any distribution any
amount on account of taxes or governmental charges, or pays any other tax in respect of such distribution (i.e., stamp duty tax, capital gains or other similar tax), the Company shall (and shall cause such agent to) remit promptly to the
Depositary information about such taxes or governmental charges withheld or paid, and, if so requested, the tax receipt (or other proof of payment to the applicable governmental authority) therefor, in each case, in a form reasonably satisfactory to
the Depositary. The Depositary shall, to the extent required by U.S. law, report to Holders any taxes withheld by it or the Custodian, and, if such information is provided to it by the Company, any taxes withheld by the Company. The Depositary and
the Custodian shall not be required to provide the Holders with any evidence of the remittance by the Company (or its agents) of any taxes withheld, or of the payment of taxes by the Company, except to the extent the evidence is provided by the
Company to the Depositary or the Custodian, as applicable. Neither the Depositary nor the Custodian shall be liable for the failure by any Holder or Beneficial Owner to obtain the benefits of credits on the basis of
non-U.S. tax paid against such Holder’s or Beneficial Owner’s income tax liability. 
 The
Depositary is under no obligation to provide the Holders and Beneficial Owners with any information about the tax status of the Company, except to the extent that the Company provides such information to the Depositary for distribution to the
Holders and Beneficial Owners. The Depositary shall not incur any liability for any tax consequences that may be incurred by Holders and Beneficial Owners on account of their ownership of the ADSs, including without limitation, tax consequences
resulting from the Company (or any of its subsidiaries) being treated as a “Passive Foreign Investment Company” (in each case as defined in the U.S. Internal Revenue Code and the regulations issued thereunder) or otherwise.

 ARTICLE V 

THE DEPOSITARY, THE CUSTODIAN AND THE COMPANY 

Section 5.1 Maintenance of Office and Transfer Books by the Registrar. Until termination of the Deposit Agreement in
accordance with its terms, the Registrar shall maintain in the United States, an office and facilities for the issuance and delivery of ADSs, the acceptance for surrender of ADS(s) for the purpose of withdrawal of Deposited Securities, the
registration of issuances, cancellations, transfers, combinations and split-ups of ADS(s) and, if applicable, to countersign ADRs evidencing the ADSs so issued, transferred, combined or split-up, in each case
in accordance with the provisions of the Deposit Agreement. 
 The Registrar shall keep books for the registration of ADSs which at all
reasonable times shall be open for inspection by the Company and by the Holders of such ADSs, provided that such inspection shall not be, to the Registrar’s knowledge, for the purpose of communicating with Holders of such ADSs in the interest
of a business or object other than the business of the Company or other than a matter related to the Deposit Agreement or the ADSs. 
 The
Registrar may close the transfer books with respect to the ADSs, at any time or from time to time, when deemed necessary or advisable by it in good faith in connection with the performance of its duties hereunder, or at the reasonable written
request of the Company subject, in all cases, to Section 7.8. 
 If any ADSs are listed on one or more stock exchanges or automated
quotation systems in the United States, the Depositary shall act as Registrar or, with written notice given as promptly as practicable to the Company, appoint a Registrar or one or more co-registrars for
registration of issuances, cancellations, transfers, combinations and split-ups of ADSs and, if applicable, to countersign ADRs evidencing the ADSs so issued, transferred, combined or split-up, in accordance with any requirements of such exchanges
or systems. Such Registrar or co-registrars may be removed and a substitute or substitutes appointed by the Depositary, upon written notice given as promptly as practicable to the Company. 

Section 5.2 Exoneration. Notwithstanding anything contained in the Deposit Agreement or any ADR, neither the Depositary nor
the Company shall be obligated to do or perform any act which is inconsistent with the provisions of the Deposit Agreement or incur any liability (i) if the Depositary or the Company shall be prevented or forbidden from, or delayed in, doing or
performing any act or thing required by the terms of the Deposit Agreement, by reason of any provision of any present or future law or regulation of the United States, the Kingdom of Belgium or any other country, or of any other governmental
authority or regulatory authority or stock exchange, or on account of the possible criminal or civil penalties or restraint, or by reason of any provision, present or future, of the Articles of Association of the Company or any provision of or
governing any Deposited Securities, or by reason of any act of God or war or other circumstances beyond its control (including, without limitation, nationalization, expropriation, currency restrictions, work stoppage, strikes, civil unrest, acts of
terrorism, revolutions, rebellions, explosions and computer failure), (ii) by reason of any exercise of, or failure to exercise, any discretion provided for in the Deposit Agreement or in the Articles of


  
 36 








 
Association of the Company or provisions of or governing Deposited Securities, (iii) for any action or inaction in reliance upon the advice of or information from legal counsel, accountants,
any person presenting Shares for deposit, any Holder, any Beneficial Owner or authorized representative thereof, or any other person believed by it in good faith to be competent to give such advice or information, (iv) for the inability by a
Holder or Beneficial Owner to benefit from any distribution, offering, right or other benefit which is made available to holders of Deposited Securities but is not, under the terms of the Deposit Agreement, made available to Holders of ADSs, or
(v) for any consequential or punitive damages (including lost profits) for any breach of the terms of the Deposit Agreement. 
 The
Depositary, its controlling persons, its agents, any Custodian and the Company, its controlling persons and its agents may rely and shall be protected in acting upon any written notice, request or other document reasonably believed by it to be
genuine and to have been signed or presented by the proper party or parties. 
 No disclaimer of liability under the Securities Act is
intended by any provision of the Deposit Agreement. 
 Section 5.3 Standard of Care. The Company and the Depositary
assume no obligation and shall not be subject to any liability under the Deposit Agreement or any ADRs to any Holder(s) or Beneficial Owner(s), except that the Company and the Depositary agree to perform their respective obligations specifically set
forth in the Deposit Agreement or the applicable ADRs without negligence or bad faith. 
 Without limitation of the foregoing, neither the
Depositary, nor the Company, nor any of their respective controlling persons, or agents, shall be under any obligation to appear in, prosecute or defend any action, suit or other proceeding in respect of any Deposited Property or in respect of the
ADSs, which in its reasonable opinion may involve it in expense or liability, unless indemnity satisfactory to it against all expense (including fees and disbursements of counsel) and liability be furnished as often as may be required (and no
Custodian shall be under any obligation whatsoever with respect to such proceedings, the responsibility of the Custodian being solely to the Depositary). 

The Depositary and its agents shall not be liable for any failure to carry out any instructions to vote any of the Deposited Securities, or
for the manner in which any vote is cast or the effect of any vote, provided that any such action or omission is in good faith, without negligence and in accordance with the terms of the Deposit Agreement. The Depositary shall not incur any
liability for any failure to determine that any distribution or action may be lawful or reasonably practicable, for the content of any information submitted to it by the Company for distribution to the Holders or for any inaccuracy of any
translation thereof, for any investment risk associated with acquiring an interest in the Deposited Property, for the validity or worth of the Deposited Property or for any tax consequences that may result from the ownership of ADSs, Shares or other
Deposited Property, for the credit-worthiness of any third party, for allowing any rights to lapse upon the terms of the Deposit Agreement, for the failure or timeliness of any notice from the Company, or for
any action of or failure to act by, or any information provided or not provided by, DTC or any DTC Participant. 

  
 37 








 The Depositary shall not be liable for any acts or omissions made by a successor depositary
whether in connection with a previous act or omission of the Depositary or in connection with any matter arising wholly after the removal or resignation of the Depositary, provided that in connection with the issue out of which such potential
liability arises the Depositary performed its obligations without negligence or bad faith while it acted as Depositary. 

Section 5.4 Resignation and Removal of the Depositary; Appointment of Successor Depositary. The Depositary may at any time
resign as Depositary hereunder by written notice of resignation delivered to the Company, such resignation to be effective on the earlier of (i) the 90th day after delivery thereof to the Company (whereupon the Depositary shall be entitled to
take the actions contemplated in Section 6.2), or (ii) the appointment by the Company of a successor depositary and its acceptance of such appointment as hereinafter provided. 

The Depositary may at any time be removed by the Company by written notice of such removal, which removal shall be effective on the later of
(i) the 90th day after delivery thereof to the Depositary (whereupon the Depositary shall be entitled to take the actions contemplated in Section 6.2), or (ii) upon the appointment by the Company of a successor depositary and its
acceptance of such appointment as hereinafter provided. 
 In case at any time the Depositary acting hereunder shall resign or be removed,
the Company shall use its reasonable best efforts to appoint a successor depositary, which shall be a bank or trust company having an office in the Borough of Manhattan, the City of New York. Every successor depositary shall be required by the
Company to execute and deliver to its predecessor and to the Company an instrument in writing accepting its appointment hereunder, and thereupon such successor depositary, without any further act or deed (except as required by applicable law), shall
become fully vested with all the rights, powers, duties and obligations of its predecessor (other than as contemplated in Sections 5.8 and 5.9). The predecessor depositary, upon payment of all sums due it and on the written request of the Company,
shall, (i) execute and deliver an instrument transferring to such successor all rights and powers of such predecessor hereunder (other than as contemplated in Sections 5.8 and 5.9), (ii) duly assign, transfer and deliver all of the
Depositary’s right, title and interest to the Deposited Property to such successor, and (iii) deliver to such successor a list of the Holders of all outstanding ADSs and such other information relating to ADSs and Holders thereof as the
successor may reasonably request. Any such successor depositary shall promptly provide notice of its appointment to such Holders. 
 Any
entity into or with which the Depositary may be merged or consolidated shall be the successor of the Depositary without the execution or filing of any document or any further act. 

Section 5.5 The Custodian. The Depositary has initially appointed Citibank International Limited as Custodian for the
purpose of the Deposit Agreement. The Custodian or its successors in acting hereunder shall be subject at all times and in all respects to the direction of the Depositary for the Deposited Property for which the Custodian acts as custodian and shall
be responsible solely to it. If any Custodian resigns or is discharged from its duties hereunder with respect to any Deposited Property and no other Custodian has previously been appointed 

  
 38 








 
hereunder, the Depositary shall promptly appoint a substitute custodian. The Depositary shall require such resigning or discharged Custodian to Deliver, or cause the Delivery of, the Deposited
Property held by it, together with all such records maintained by it as Custodian with respect to such Deposited Property as the Depositary may request, to the Custodian designated by the Depositary. Whenever the Depositary determines, in its
discretion, that it is appropriate to do so, it may appoint an additional custodian with respect to any Deposited Property, or discharge the Custodian with respect to any Deposited Property and appoint a substitute custodian, which shall thereafter
be Custodian hereunder with respect to the Deposited Property. Immediately upon any such change, the Depositary shall give notice thereof in writing to all Holders of ADSs, each other Custodian and the Company. 

Citibank, N.A. may at any time act as Custodian of the Deposited Property pursuant to the Deposit Agreement, in which case any reference to
Custodian shall mean Citibank, N.A. solely in its capacity as Custodian pursuant to the Deposit Agreement, and the Depositary shall promptly give notice thereof to the Company. Notwithstanding anything contained in the Deposit Agreement or any ADR,
the Depositary shall not be obligated to give notice to any Holders of ADSs or any other Custodian of its acting as Custodian pursuant to the Deposit Agreement. 

Upon the appointment of any successor depositary, any Custodian then acting hereunder shall, unless otherwise instructed by the Depositary,
continue to be the Custodian of the Deposited Property without any further act or writing, and shall be subject to the direction of the successor depositary. The successor depositary so appointed shall, nevertheless, on the written request of any
Custodian, execute and deliver to such Custodian all such instruments as may be proper to give to such Custodian full and complete power and authority to act on the direction of such successor depositary. 

The Depositary shall cause the Custodian to be at all time a participant of the securities settlement system operated by Euroclear. 

Section 5.6 Notices and Reports. On or before the first date on which the Company gives notice, by publication or
otherwise, of any meeting of holders of Shares or other Deposited Securities, or of any adjourned meeting of such holders, or of the taking of any action by such holders other than at a meeting, or of the taking of any action in respect of any cash
or other distributions or the offering of any rights in respect of Deposited Securities, the Company shall transmit to the Depositary and the Custodian a copy of the notice thereof in the English language but otherwise in the form given or to be
given to holders of Shares or other Deposited Securities. The Company shall also furnish to the Custodian and the Depositary a summary, in English, of any applicable provisions or proposed provisions of the Articles of Association of the Company
that may be relevant or pertain to such notice of meeting or be the subject of a vote thereat. 
 The Depositary shall arrange, at the
request of the Company and at the Company’s expense, to provide copies thereof to all Holders or make such notices, reports and other communications available to all Holders on a basis similar to that for holders of Shares or other Deposited
Securities or on such other basis as the Company may advise the Depositary or as may be required by any applicable law, regulation or stock exchange requirement. The Company has 

  
 39 








 
delivered to the Depositary and the Custodian a copy of the Company’s Articles of Association along with the provisions of or governing the Shares and any other Deposited Securities issued
by the Company in connection with such Shares, and promptly upon any amendment thereto or change therein, the Company shall deliver to the Depositary and the Custodian a copy of such amendment thereto or change therein. The Depositary may rely upon
such copy for all purposes of the Deposit Agreement. 
 The Depositary will, at the expense of the Company, make available a copy of any
such notices, reports or communications issued by the Company and delivered to the Depositary for inspection by the Holders of the ADSs at the Depositary’s Principal Office, at the office of the Custodian and at any other designated transfer
office. 
 Section 5.7 Issuance of Additional Shares, ADSs etc. The Company agrees that in the event it or any of its
Affiliates proposes (i) an issuance, sale or distribution of additional Shares, (ii) an offering of rights to subscribe for Shares or other Deposited Securities, (iii) an issuance or assumption of securities convertible into or
exchangeable for Shares, (iv) an issuance of rights to subscribe for securities convertible into or exchangeable for Shares, (v) an elective dividend of cash or Shares, (vi) a redemption of Deposited Securities, (vii) a meeting
of holders of Deposited Securities, or solicitation of consents or proxies, relating to any reclassification of securities, merger or consolidation or transfer of assets, (viii) any assumption, reclassification, recapitalization,
reorganization, merger, consolidation or sale of assets which affects the Deposited Securities, or (ix) a distribution of securities other than Shares, provided any such corporate action is available to the holders of Shares as a class, it will
obtain U.S. legal advice and take all steps necessary to ensure that the proposed transaction does not violate the registration provisions of the Securities Act, or any other applicable laws (including, without limitation, the Investment Company Act
of 1940, as amended, the Exchange Act and the securities laws of the states of the U.S.). In support of the foregoing, the Company will furnish to the Depositary (a) a written opinion of U.S. counsel (reasonably satisfactory to the Depositary)
stating whether such transaction (1) requires a registration statement under the Securities Act to be in effect or (2) is exempt from the registration requirements of the Securities Act and (b) an opinion of Belgian counsel stating
that (1) making the transaction available to Holders and Beneficial Owners does not violate the laws or regulations of the Kingdom of Belgium and (2) all requisite regulatory consents and approvals have been obtained in the Kingdom of
Belgium. If the filing of a registration statement is required, the Depositary shall not have any obligation to proceed with the transaction unless it shall have received evidence reasonably satisfactory to it that such registration statement has
been declared effective. If, being advised by counsel, the Company determines that a transaction is required to be registered under the Securities Act, the Company will either (i) register such transaction to the extent necessary,
(ii) alter the terms of the transaction to avoid the registration requirements of the Securities Act or (iii) direct the Depositary to take specific measures, in each case as contemplated in the Deposit Agreement, to prevent such
transaction from violating the registration requirements of the Securities Act. The Company agrees with the Depositary that neither the Company nor any of its Affiliates will at any time (i) deposit any Shares or other Deposited Securities,
either upon original issuance or upon a sale of Shares or other Deposited Securities previously issued and reacquired by the Company or by any such Affiliate, or (ii) issue additional Shares, rights to subscribe for such Shares, securities
convertible into or exchangeable for Shares or rights to subscribe for such 

  
 40 








 
securities or distribute securities other than Shares, unless such transaction and the securities issuable in such transaction do not violate the registration provisions of the Securities Act, or
any other applicable laws (including, without limitation, the Investment Company Act of 1940, as amended, the Exchange Act and the securities laws of the states of the U.S.). 

Notwithstanding anything else contained in the Deposit Agreement, nothing in the Deposit Agreement shall be deemed to obligate the Company to
file any registration statement in respect of any proposed transaction. 
 Section 5.8 Indemnification. The Depositary
agrees to indemnify the Company and its directors, officers, employees, agents and Affiliates against, and hold each of them harmless from, any direct loss, liability, tax, charge or expense of any kind whatsoever (including, but not limited to, the
reasonable fees and expenses of counsel) which may arise out of acts performed or omitted by the Depositary under the terms hereof due to the negligence or bad faith of the Depositary. 

The Company agrees to indemnify the Depositary, the Custodian and any of their respective directors, officers, employees, agents and
Affiliates against, and hold each of them harmless from, any direct loss, liability, tax, charge or expense of any kind whatsoever (including, but not limited to, the reasonable fees and expenses of counsel) that may arise (a) out of, or in
connection with, any offer, issuance, sale, resale, transfer, deposit or withdrawal of ADRs, ADSs, the Shares, or other Deposited Securities, as the case may be, (b) out of, or as a result of, any offering documents in respect thereof or
(c) out of acts performed or omitted, including, but not limited to, any delivery by the Depositary on behalf of the Company of information regarding the Company in connection with the Deposit Agreement, the ADRs, the ADSs, the Shares, or any
Deposited Property, in any such case (i) by the Depositary, the Custodian or any of their respective directors, officers, employees, agents and Affiliates, except to the extent such loss, liability, tax, charge or expense is due to the
negligence or bad faith of any of them, or (ii) by the Company or any of its directors, officers, employees, agents and Affiliates, provided, however, that the Company shall not be liable for any fees, charges or expenses payable by Holders or
Beneficial Owners under this Deposit Agreement. The Company shall not indemnify the Depositary or the Custodian against any liability or expense arising out of information relating to the Depositary or such Custodian, as the case may be, furnished
in a writing to the Company, by the Depositary or such Custodian expressly for use in any registration statement, prospectus or preliminary prospectus relating to any Deposited Securities represented by the ADSs. The indemnities contained in this
paragraph shall not extend to any liability or expense that may arise solely and exclusively out of any Pre-Release Transaction (as defined in Section 5.10), other than a Pre-Release Transaction entered into at the request of the Company. 

The obligations set forth in this Section shall survive the termination of the Deposit Agreement and the succession or substitution of any
party hereto. 
 Any person seeking indemnification hereunder (an “indemnified person”) shall notify the person from whom it is
seeking indemnification (the “indemnifying person”) of the commencement of any indemnifiable action or claim promptly after such indemnified person 

  
 41 








 
becomes aware of such commencement (provided that the failure to make such notification shall not affect such indemnified person’s rights to seek indemnification except to the extent the
indemnifying person is materially prejudiced by such failure) and shall consult in good faith with the indemnifying person as to the conduct of the defense of such action or claim that may give rise to an indemnity hereunder, which defense shall be
reasonable in the circumstances. No indemnified person shall compromise or settle any action or claim that may give rise to an indemnity hereunder without the consent of the indemnifying person, which consent shall not be unreasonably withheld. 

Section 5.9 ADS Fees and Charges. The Company, the Holders, the Beneficial Owners, and persons depositing Shares for
issuance of ADSs or surrendering ADSs for cancellation and withdrawal of Deposited Securities shall be required to pay the ADS fees and charges identified as payable by them respectively in the ADS fee schedule attached hereto as Exhibit B. All ADS
fees and charges so payable may be deducted from distributions or must be remitted to the Depositary, or its designee, and may, at any time and from time to time, be changed by agreement between the Depositary and the Company, but, in the case of
ADS fees and charges payable by Holders and Beneficial Owners, only in the manner contemplated in Section 6.1. The Depositary shall provide, without charge, a copy of its latest ADS fee schedule to anyone upon request. 

ADS fees and charges payable upon (i) deposit of Shares against issuance of ADSs and (ii) surrender of ADSs for cancellation and
withdrawal of Deposited Securities will be payable by the person to whom the ADSs so issued are delivered by the Depositary (in the case of ADS issuances) and by the person who delivers the ADSs for cancellation to the Depositary (in the case of ADS
cancellations). In the case of ADSs issued by the Depositary into DTC or presented to the Depositary via DTC, the ADS issuance and cancellation fees and charges will be payable by the DTC Participant(s) receiving the ADSs from the Depositary or the
DTC Participant(s) surrendering the ADSs to the Depositary for cancellation, as the case may be, on behalf of the Beneficial Owner(s) and will be charged by the DTC Participant(s) to the account(s) of the applicable Beneficial Owner(s) in accordance
with the procedures and practices of the DTC participant(s) as in effect at the time. ADS fees and charges in respect of distributions and the ADS service fee are payable by Holders as of the applicable ADS Record Date established by the Depositary.
In the case of distributions of cash, the amount of the applicable ADS fees and charges is deducted from the funds being distributed. In the case of (i) distributions other than cash and (ii) the ADS service fee, the applicable Holders as
of the ADS Record Date established by the Depositary will be invoiced for the amount of the ADS fees and charges and such ADS fees may be deducted from distributions made to Holders. For ADSs held through DTC, the ADS fees and charges for
distributions other than cash and the ADS service fee may be deducted from distributions made through DTC, and may be charged to the DTC Participants in accordance with the procedures and practices prescribed by DTC from time to time and the DTC
Participants in turn charge the amount of such ADS fees and charges to the Beneficial Owners for whom they hold ADSs. 

  
 42 








 The Depositary may reimburse the Company for certain expenses incurred by the Company in respect
of the ADR program established pursuant to the Deposit Agreement, by making available a portion of the ADS fees charged in respect of the ADR program or otherwise, upon such terms and conditions as the Company and the Depositary agree from time to
time. The Company shall pay to the Depositary such fees and charges, and reimburse the Depositary for such out-of-pocket expenses, as the Depositary and the Company may agree from time to time. Responsibility for payment of such fees, charges and
reimbursements may from time to time be changed by agreement between the Company and the Depositary. Unless otherwise agreed, the Depositary shall present its statement for such fees, charges and reimbursements to the Company once every three
months. The charges and expenses of the Custodian are for the sole account of the Depositary. 
 The obligation of Holders and Beneficial
Owners to pay ADS fees and charges shall survive the termination of the Deposit Agreement. As to any Depositary, upon the resignation or removal of such Depositary as described in Section 5.4, the right to collect ADS fees, charges and expenses
shall extend for those ADS fees and charges incurred prior to the effectiveness of such resignation or removal. 
 Section 5.10
Pre-Release Transactions. Subject to the further terms and provisions of this Section 5.10, and subject to any applicable securities laws and regulations (including without limitation any insider dealing restrictions), the
Depositary, its Affiliates and their agents, on their own behalf, may own and deal in any class of securities of the Company and its Affiliates and in ADSs. In its capacity as Depositary, the Depositary shall not lend Shares or ADSs; provided,
however, that the Depositary may (i) issue ADSs prior to the receipt of Shares pursuant to Section 2.3 and (ii) deliver Shares prior to the receipt of ADSs for withdrawal of Deposited Securities pursuant to Section 2.7, including
ADSs which were issued under (i) above but for which Shares may not have been received (each such transaction a “Pre-Release Transaction”). The Depositary may receive ADSs in lieu of Shares under (i) above and receive
Shares in lieu of ADSs under (ii) above. Each such Pre-Release Transaction will be (a) subject to a written agreement whereby the person or entity (the “Applicant”) to whom ADSs or Shares are to be delivered
(w) represents that at the time of the Pre-Release Transaction the Applicant or its customer owns the Shares or ADSs that are to be delivered by the Applicant under such Pre-Release Transaction, (x) agrees to indicate the Depositary as
owner of such Shares or ADSs in its records and to hold such Shares or ADSs in trust for the Depositary until such Shares or ADSs are delivered to the Depositary or the Custodian, (y) unconditionally guarantees to deliver to the Depositary or
the Custodian, as applicable, such Shares or ADSs, and (z) agrees to any additional restrictions or requirements that the Depositary deems appropriate, (b) at all times fully collateralized with cash, U.S. government securities or such
other collateral as the Depositary deems appropriate, (c) terminable by the Depositary on not more than five (5) business days’ notice and (d) subject to such further indemnities and credit regulations as the Depositary deems
appropriate. The Depositary will normally limit the number of ADSs and Shares involved in such Pre-Release Transactions at any one time to thirty percent (30%) of the ADSs outstanding (without giving effect to ADSs outstanding under
(i) above), provided, however, that the Depositary reserves the right to change or disregard such limit from time to time as it deems appropriate. 

  
 43 








 The Depositary may also set limits with respect to the number of ADSs and Shares involved in
Pre-Release Transactions with any one person on a case-by-case basis as it deems appropriate. The Depositary may retain for its own account any compensation received by it in conjunction with the foregoing. Collateral provided pursuant to
(b) above, but not the earnings thereon, shall be held for the benefit of the Holders (other than the Applicant). 

Section 5.11 Restricted Securities Owners. The Company agrees to advise in writing each of the persons or entities who, to
the knowledge of the Company, holds Restricted Securities that such Restricted Securities are ineligible for deposit hereunder (except under the circumstances contemplated in Section 2.14) and, to the extent practicable, shall require each of
such persons to represent in writing that such person will not deposit Restricted Securities hereunder (except under the circumstances contemplated in Section 2.14). 

ARTICLE VI 
 AMENDMENT
AND TERMINATION 
 Section 6.1 Amendment/Supplement. Subject to the terms and conditions of this Section 6.1 and
applicable law, the ADRs outstanding at any time, the provisions of the Deposit Agreement and the form of ADR attached hereto and to be issued under the terms hereof may at any time and from time to time be amended or supplemented by written
agreement between the Company and the Depositary in any respect which they may deem necessary or desirable without the prior written consent of the Holders or Beneficial Owners. Any amendment or supplement which shall impose or increase any fees or
charges (other than charges in connection with foreign exchange control regulations, and taxes and other governmental charges, delivery and other such expenses), or which shall otherwise materially prejudice any substantial existing right of Holders
or Beneficial Owners, shall not, however, become effective as to outstanding ADSs until the expiration of thirty (30) days after notice of such amendment or supplement shall have been given to the Holders of outstanding ADSs. Notice of any
amendment to the Deposit Agreement or any ADR shall not need to describe in detail the specific amendments effectuated thereby, and failure to describe the specific amendments in any such notice shall not render such notice invalid, provided,
however, that, in each such case, the notice given to the Holders identifies a means for Holders and Beneficial Owners to retrieve or receive the text of such amendment (i.e., upon retrieval from the Commission’s, the
Depositary’s or the Company’s website or upon request from the Depositary). The parties hereto agree that any amendments or supplements which (i) are reasonably necessary (as agreed by the Company and the Depositary) in order for
(a) the ADSs to be registered on Form F-6 under the Securities Act or (b) the ADSs to be settled solely in electronic book-entry form and (ii) do not in either such case impose or increase any
fees or charges to be borne by Holders, shall be deemed not to materially prejudice any substantial rights of Holders or Beneficial Owners. Every Holder and Beneficial Owner at the time any amendment or supplement so becomes effective shall be
deemed, by continuing to hold such ADSs, to consent and agree to such amendment or supplement and to be bound by the Deposit Agreement and the ADR, if applicable, as amended or supplemented thereby. In no event shall any amendment or supplement
impair the right of the Holder to surrender such ADS and receive therefor the Deposited Securities represented thereby, except in order to comply with mandatory provisions of applicable law. Notwithstanding the foregoing, if any governmental


  
 44 








 
body should adopt new laws, rules or regulations which would require an amendment of, or supplement to, the Deposit Agreement to ensure compliance therewith, the Company and the Depositary may
amend or supplement the Deposit Agreement and any ADRs at any time in accordance with such changed laws, rules or regulations. Such amendment or supplement to the Deposit Agreement and any ADRs in such circumstances may become effective before a
notice of such amendment or supplement is given to Holders or within any other period of time as required for compliance with such laws, rules or regulations. 

Section 6.2 Termination. The Depositary shall, at any time at the written direction of the Company, terminate the Deposit
Agreement by distributing notice of such termination to the Holders of all ADSs then outstanding at least thirty (30) days prior to the date fixed in such notice for such termination. If ninety (90) days shall have expired after
(i) the Depositary shall have delivered to the Company a written notice of its election to resign, or (ii) the Company shall have delivered to the Depositary a written notice of the removal of the Depositary, and, in either case, a
successor depositary shall not have been appointed and accepted its appointment as provided in Section 5.4 of the Deposit Agreement, the Depositary may terminate the Deposit Agreement by distributing notice of such termination to the Holders of
all ADSs then outstanding at least thirty (30) days prior to the date fixed in such notice for such termination. The date so fixed for termination of the Deposit Agreement in any termination notice so distributed by the Depositary to the
Holders of ADSs is referred to as the “Termination Date”. Until the Termination Date, the Depositary shall continue to perform all of its obligations under the Deposit Agreement, and the Holders and Beneficial Owners will be
entitled to all of their rights under the Deposit Agreement. 
 If any ADSs shall remain outstanding after the Termination Date, the
Registrar and the Depositary shall not, after the Termination Date, have any obligation to perform any further acts under the Deposit Agreement, except that the Depositary shall, subject, in each case, to the terms and conditions of the Deposit
Agreement, continue to (i) collect dividends and other distributions pertaining to Deposited Securities, (ii) sell Deposited Property received in respect of Deposited Securities, (iii) deliver Deposited Securities, together with any
dividends or other distributions received with respect thereto and the net proceeds of the sale of any other Deposited Property, in exchange for ADSs surrendered to the Depositary (after deducting, or charging, as the case may be, in each case, the
fees and charges of, and expenses incurred by, the Depositary, and all applicable taxes or governmental charges for the account of the Holders and Beneficial Owners, in each case upon the terms set forth in Section 5.9 of the Deposit
Agreement), and (iv) take such actions as may be required under applicable law in connection with its role as Depositary under the Deposit Agreement. 

At any time after the Termination Date, the Depositary may sell the Deposited Property then held under the Deposit Agreement and shall after
such sale hold un-invested the net proceeds of such sale, together with any other cash then held by it under the Deposit Agreement, in an un-segregated account and without liability for interest, for the pro rata benefit of the Holders whose ADSs
have not theretofore been surrendered. After making such sale, the Depositary shall be discharged from all obligations under the Deposit Agreement except (i) to account for such net proceeds and other cash (after deducting, or charging, as the
case may be, in each case, the fees and charges of, and expenses incurred by, the Depositary, and all applicable 

  
 45 








 
taxes or governmental charges for the account of the Holders and Beneficial Owners, in each case upon the terms set forth in Section 5.9 of the Deposit Agreement), and (ii) as may be
required at law in connection with the termination of the Deposit Agreement. After the Termination Date, the Company shall be discharged from all obligations under the Deposit Agreement, except for its obligations to the Depositary under Sections
5.8, 5.9 and 7.6 of the Deposit Agreement. The obligations under the terms of the Deposit Agreement of Holders and Beneficial Owners of ADSs outstanding as of the Termination Date shall survive the Termination Date and shall be discharged only when
the applicable ADSs are presented by their Holders to the Depositary for cancellation under the terms of the Deposit Agreement. 
 ARTICLE
VII 
 MISCELLANEOUS 

Section 7.1 Counterparts. The Deposit Agreement may be executed in any number of counterparts, each of which shall be
deemed an original and all of such counterparts together shall constitute one and the same agreement. Copies of the Deposit Agreement shall be maintained with the Depositary and shall be open to inspection by any Holder during business hours. 

Section 7.2 No Third-Party Beneficiaries. The Deposit Agreement is for the
exclusive benefit of the parties hereto (and their successors) and shall not be deemed to give any legal or equitable right, remedy or claim whatsoever to any other person, except to the extent specifically set forth in the Deposit Agreement.
Nothing in the Deposit Agreement shall be deemed to give rise to a partnership or joint venture among the parties nor establish a fiduciary or similar relationship among the parties. The parties hereto acknowledge and agree that (i) the
Depositary and its Affiliates may at any time have multiple banking relationships with the Company and its Affiliates, (ii) the Depositary and its Affiliates may be engaged at any time in transactions in which parties adverse to the Company or
the Holders or Beneficial Owners may have interests and (iii) nothing contained in the Deposit Agreement shall (a) preclude the Depositary or any of its Affiliates from engaging in such transactions or establishing or maintaining such
relationships, and (b) obligate the Depositary or any of its Affiliates to disclose such transactions or relationships or to account for any profit made or payment received in such transactions or relationships. 

Section 7.3 Severability. In case any one or more of the provisions contained in the Deposit Agreement or in the ADRs
should be or become invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein or therein shall in no way be affected, prejudiced or disturbed thereby. 

Section 7.4 Holders and Beneficial Owners as Parties; Binding Effect. The Holders and Beneficial Owners from time to time
of ADSs issued hereunder shall be parties to the Deposit Agreement and shall be bound by all of the terms and conditions hereof and of any ADR evidencing their ADSs by acceptance thereof or any beneficial interest therein. 

  
 46 








 Section 7.5 Notices. Any and all notices to be given to the Company shall be
deemed to have been duly given if personally delivered or sent by mail, air courier or cable, telex or facsimile transmission, confirmed by letter personally delivered or sent by mail or air courier, addressed to Celyad SA, Rue Edouard Belin 12,
1435 Mont-Saint-Guibert, Belgium, Attention: Legal Department, or to any other address which the Company may specify in writing to the Depositary. 

Any and all notices to be given to the Depositary shall be deemed to have been duly given if personally delivered or sent by mail, air courier
or cable, telex or facsimile transmission, confirmed by letter personally delivered or sent by mail or air courier, addressed to Citibank, N.A., 388 Greenwich Street, New York, New York 10013, U.S.A., Attention: Depositary Receipts
Department, or to any other address which the Depositary may specify in writing to the Company. 
 Any and all notices to be given to any
Holder shall be deemed to have been duly given if (a) personally delivered or sent by mail or cable, telex or facsimile transmission, confirmed by letter, addressed to such Holder at the address of such Holder as it appears on the books of the
Depositary or, if such Holder shall have filed with the Depositary a request that notices intended for such Holder be mailed to some other address, at the address specified in such request, or (b) if a Holder shall have designated such means of
notification as an acceptable means of notification under the terms of the Deposit Agreement, by means of electronic messaging addressed for delivery to the e-mail address designated by the Holder for such purpose. Notice to Holders shall be deemed
to be notice to Beneficial Owners for all purposes of the Deposit Agreement. Failure to notify a Holder or any defect in the notification to a Holder shall not affect the sufficiency of notification to other Holders or to the Beneficial Owners of
ADSs held by such other Holders. 
 Delivery of a notice sent by mail, air courier or cable, telex or facsimile transmission shall be deemed
to be effective at the time when a duly addressed letter containing the same (or a confirmation thereof in the case of a cable, telex or facsimile transmission) is deposited, postage prepaid, in a post-office letter box or delivered to an air
courier service, without regard for the actual receipt or time of actual receipt thereof by a Holder. The Depositary or the Company may, however, act upon any cable, telex or facsimile transmission received by it from any Holder, the Custodian, the
Depositary, or the Company, notwithstanding that such cable, telex or facsimile transmission shall not be subsequently confirmed by letter. 

Delivery of a notice by means of electronic messaging shall be deemed to be effective at the time of the initiation of the transmission by the
sender (as shown on the sender’s records), notwithstanding that the intended recipient retrieves the message at a later date, fails to retrieve such message, or fails to receive such notice on account of its failure to maintain the designated
e-mail address, its failure to designate a substitute e-mail address or for any other reason. 
 Section 7.6 Governing Law and
Jurisdiction. The Deposit Agreement and the ADRs shall be interpreted in accordance with, and all rights hereunder and thereunder and provisions hereof and thereof shall be governed by, the laws of the State of New York applicable to
contracts made and to be wholly performed in that State. Notwithstanding anything contained 

  
 47 








 
in the Deposit Agreement, any ADR or any present or future provisions of the laws of the State of New York, the rights of holders of Shares and of any other Deposited Securities and the
obligations and duties of the Company in respect of the holders of Shares and other Deposited Securities, as such, shall be governed by the laws of the Kingdom of Belgium (or, if applicable, such other laws as may govern the Deposited Securities).

 Except as set forth in the following paragraph of this Section 7.6, the Company and the Depositary agree that the federal or state
courts in the City of New York shall have jurisdiction to hear and determine any suit, action or proceeding and to settle any dispute between them that may arise out of or in connection with the Deposit Agreement and, for such purposes, each
irrevocably submits to the non-exclusive jurisdiction of such courts. The Company hereby irrevocably designates, appoints and empowers CT Corporation System (the “Agent”) at 111 8th Avenue, New York, New York 10011 as its authorized
agent to receive and accept for and on its behalf, and on behalf of its properties, assets and revenues, service by mail of any and all legal process, summons, notices and documents that may be served in any suit, action or proceeding brought
against the Company in any federal or state court as described in the preceding sentence or in the next paragraph of this Section 7.6. If for any reason the Agent shall cease to be available to act as such, the Company agrees to designate a new
agent in New York on the terms and for the purposes of this Section 7.6 reasonably satisfactory to the Depositary. The Company further hereby irrevocably consents and agrees to the service of any and all legal process, summons, notices and
documents in any suit, action or proceeding against the Company, by service by mail of a copy thereof upon the Agent (whether or not the appointment of such Agent shall for any reason prove to be ineffective or such Agent shall fail to accept or
acknowledge such service), with a copy mailed to the Company by registered or certified air mail, postage prepaid, to its address provided in Section 7.5. The Company agrees that the failure of the Agent to give any notice of such service to it
shall not impair or affect in any way the validity of such service or any judgment rendered in any action or proceeding based thereon. 

Notwithstanding the foregoing, the Depositary and the Company unconditionally agree that in the event that a Holder or Beneficial Owner brings
a suit, action or proceeding against (a) the Company, (b) the Depositary in its capacity as Depositary under the Deposit Agreement or (c) against both the Company and the Depositary, in any such case, in any state or federal court of
the United States, and the Depositary or the Company have any claim, for indemnification or otherwise, against each other arising out of the subject matter of such suit, action or proceeding, then the Company and the Depositary may pursue such claim
against each other in the state or federal court in the United States in which such suit, action, or proceeding is pending and, for such purposes, the Company and the Depositary irrevocably submit to the non-exclusive jurisdiction of such courts.
The Company agrees that service of process upon the Agent in the manner set forth in the preceding paragraph shall be effective service upon it for any suit, action or proceeding brought against it as described in this paragraph. 

The Company irrevocably and unconditionally waives, to the fullest extent permitted by law, any objection that it may now or hereafter have to
the laying of venue of any actions, suits or proceedings brought in any court as provided in this Section 7.6, and hereby further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such action,
suit or proceeding brought in any such court has been brought in an inconvenient forum. 

  
 48 








 The Company irrevocably and unconditionally waives, to the fullest extent permitted by law, and
agrees not to plead or claim, any right of immunity from legal action, suit or proceeding, from setoff or counterclaim, from the jurisdiction of any court, from service of process, from attachment upon or prior to judgment, from attachment in aid of
execution or judgment, from execution of judgment, or from any other legal process or proceeding for the giving of any relief or for the enforcement of any judgment, and consents to such relief and enforcement against it, its assets and its revenues
in any jurisdiction, in each case with respect to any matter arising out of, or in connection with, the Deposit Agreement, any ADR or the Deposited Property. 

No disclaimer of liability under the Securities Act is intended by any provision of the Deposit Agreement. The provisions of this
Section 7.6 shall survive any termination of the Deposit Agreement, in whole or in part. 
 Section 7.7 Assignment.
Subject to the provisions of Section 5.4, the Deposit Agreement may not be assigned by either the Company or the Depositary. 

Section 7.8 Compliance with U.S. Securities Laws. Notwithstanding anything in the Deposit Agreement to the contrary, the
withdrawal or delivery of Deposited Securities will not be suspended by the Company or the Depositary except as would be permitted by Instruction I.A.(1) of the General Instructions to Form F-6 Registration Statement, as amended from time to time,
under the Securities Act. 
 Section 7.9 Belgian Law References. Any summary of Belgian laws and regulations and of the
terms of the Company’s Articles of Association set forth in the Deposit Agreement have been provided by the Company solely for the convenience of Holders, Beneficial Owners and the Depositary. While such summaries are believed by the Company to
be accurate as of the date of the Deposit Agreement, (i) they are summaries and as such may not include all aspects of the materials summarized applicable to a Holder or Beneficial Owner, and (ii) these laws and regulations and the
Company’s Articles of Association may change after the date of the Deposit Agreement. Neither the Depositary nor the Company has any obligation under the terms of the Deposit Agreement to update any such summaries.

 (1) The Deposit Agreement. This American Depositary Receipt is one of an issue of
American Depositary Receipts (“ADRs”), all issued and to be issued upon the terms and conditions set forth in the Deposit Agreement, dated as of [DATE], 2015 (as amended and supplemented from time to time, the “Deposit
Agreement”), by and among the Company, the Depositary, and all Holders and Beneficial Owners from time to time of ADSs issued thereunder. The Deposit Agreement sets forth the rights and obligations of Holders and Beneficial Owners of ADSs and
the rights and duties of the Depositary in respect of the Shares deposited thereunder and any and all other Deposited Property (as defined in the Deposit Agreement) from time to time received and held on deposit in respect of the ADSs. Copies of the
Deposit Agreement are on file at the Principal Office of the Depositary and with the Custodian. Each Holder and each Beneficial Owner, upon acceptance of any ADSs (or any interest therein) issued in accordance with the terms and conditions of the
Deposit Agreement, shall be deemed for all purposes to (a) be a party to and bound by the terms of the Deposit Agreement and the applicable ADR(s), and (b) appoint the Depositary its attorney-in-fact, with full power to delegate, to act on its behalf and to take any and all actions contemplated in the Deposit Agreement and the applicable ADR(s), to adopt any and all procedures necessary
to comply with applicable law and to take such action as the Depositary in its sole discretion may deem necessary or appropriate to carry out the purposes of the Deposit Agreement and the applicable ADR(s), the taking of such actions to be the
conclusive determinant of the necessity and appropriateness thereof. 
 The statements made on the face and reverse of this ADR are
summaries of certain provisions of the Deposit Agreement and the Articles of Association of the Company (as in effect on the date of the signing of the Deposit Agreement) and are qualified by and subject to the detailed provisions of the Deposit
Agreement and the Articles of Association, to which reference is hereby made. 
 All capitalized terms used herein which are not otherwise
defined herein shall have the meanings ascribed thereto in the Deposit Agreement. 
 The Depositary makes no representation or warranty as
to the validity or worth of the Deposited Property. The Depositary has made arrangements for the acceptance of the ADSs into DTC. Each Beneficial Owner of ADSs held through DTC must rely on the procedures of DTC and the DTC Participants to exercise
and be entitled to any rights attributable to such ADSs. The Depositary may issue Uncertificated ADSs subject, however, to the terms and conditions of Section 2.13 of the Deposit Agreement.

Depositary or the Custodian may require (i) payment from the depositor of Shares or presenter of ADSs or of this ADR of a sum sufficient to reimburse it for any tax or other governmental charge and any stock transfer or registration fee with
respect thereto (including any such tax or charge and fee with respect to Shares being deposited or withdrawn) and payment of any applicable fees and charges of the Depositary as provided in Section 5.9 and Exhibit B to the Deposit
Agreement and in this ADR, (ii) the production of proof reasonably satisfactory to it as to the identity and genuineness of any signature or any other matter contemplated by Section 3.1 of the Deposit Agreement, and (iii) compliance

consistent with the provisions of this ADR, if applicable, the Deposit Agreement and applicable law. 
 The issuance of ADSs against
deposits of Shares generally or against deposits of particular Shares may be suspended, or the deposit of particular Shares may be refused, or the registration of transfer of ADSs in particular instances may be refused, or the registration of
transfer of ADSs generally may be suspended, during any period when the transfer books of the Company, the Depositary, a Registrar or any Settlement System are closed or if any such action is deemed necessary or advisable by the Depositary or the
Company, in good faith, at any time or from time to time because of any requirement of law or regulation, any government or governmental body or commission or any securities exchange on which the ADSs or Shares are listed, or under any provision of
the Deposit Agreement or this ADR, if applicable, or under any provision of, or governing, the Deposited Securities, or because of a meeting of shareholders of the Company or for any other reason, subject, in all cases to paragraph (25) of this
ADR and Section 7.8 of the Deposit Agreement. Notwithstanding any provision of the Deposit Agreement or this ADR to the contrary, Holders are entitled to surrender outstanding ADSs to withdraw the Deposited Securities associated therewith at

Owner owns ADSs (and the Shares represented by such ADSs, as the case may be) and regarding the identity of any other person(s) interested in such ADSs (and the Shares represented by such ADSs, as the case may be) and the nature of such interest and
various other matters, whether or not they are Holders and/or Beneficial Owners at the time of such request. The Depositary agrees to use its reasonable efforts to forward, upon the request of the Company and at the Company’s expense, any such
request from the Company to the Holders and to forward to the Company, as promptly as practicable, any such responses to such requests received by the Depositary. 

(6) Ownership Restrictions. Subject to applicable law, notwithstanding any other provision of this ADR or of the Deposit
Agreement, the Company may restrict transfers of the Shares where such transfer might result in ownership of Shares exceeding limits imposed by applicable law or the Articles of Association of the Company. The Company may also restrict, in such
manner as it deems appropriate, transfers of the ADSs where such transfer may result in the total number of Shares represented by the ADSs owned by a single Holder or Beneficial Owner to exceed any such limits. The Company may, in its sole
discretion but subject to applicable law, instruct the Depositary to take action with respect to the ownership interest of any Holder or Beneficial Owner in excess of the limits set forth in the preceding sentence, including but not limited to, the
imposition of restrictions on the transfer of ADSs, the removal or limitation of voting rights or the mandatory sale or disposition on behalf of a Holder or Beneficial Owner of the Shares represented by the ADSs held by such Holder or Beneficial
Owner in excess of such limitations, if and to the extent such disposition is permitted by applicable law and the Articles of Association of the Company. Nothing herein or in the Deposit Agreement shall be interpreted as obligating the Depositary or
the Company to ensure compliance with the ownership restrictions described herein or in Section 3.5 of the Deposit Agreement. 
 (7)
Reporting Obligations and Regulatory Approvals; Disclosure of Interests. Applicable laws and regulations may require holders and beneficial owners of Shares, including the Holders and Beneficial Owners of ADSs, to satisfy reporting
requirements and obtain regulatory approvals in certain circumstances. Holders and Beneficial Owners of ADSs are solely responsible for determining and complying with such reporting requirements and for obtaining such approvals. Each Holder and each
Beneficial Owner hereby agrees to make such determination, file such reports, and obtain such approvals to the extent and in the form required by applicable laws and regulations as in effect from time to time. Neither the Depositary, the Custodian,
the Company or any of their respective agents or affiliates shall be required to take any actions whatsoever on behalf of Holders or Beneficial Owners to determine or satisfy such reporting requirements or obtain such regulatory approvals under
applicable laws and regulations.

 The Company has advised the Depositary and the parties to the Deposit Agreement acknowledge that,
Belgian law, as in effect on the date of the Deposit Agreement, provides that: 
 (a) Any person or legal entity, which owns or acquires
securities of the Company granting voting rights (including Shares) (either directly or by ownership of ADSs or both), whether representing the share capital or not, must disclose to the Company and to the Belgian Financial Services and Markets
Authority (FSMA) the number of securities that such person or legal entity owns, alone or jointly with one or several other persons or legal entities, when the voting rights attached to such securities amount to 5 percent or more of the total of the
voting rights existing when the situation triggering the disclosure obligation occurs. Such person or legal entity must make the same disclosure in the event of a transfer or of an additional acquisition of such securities when, after such
transaction, the voting rights attached to securities owned by such person or legal entity amount to 5 percent, 10 percent, and so on by blocks of 5 percent of the total of the voting rights existing when the situation triggering the disclosure
obligation occurs, or when the voting rights attached to securities owned by such person or legal entity fall below one of the thresholds referred to in this Paragraph (7)(a); 

(b) Any person or legal entity which acquires or transfers, alone or jointly, the direct or indirect control of a corporation or other legal
entity which owns 5 percent at least of the voting rights of the Company (either directly or by ownership of ADSs or both) must disclose such acquisition or transfer to the Company and to the FSMA; 

(c) A disclosure described above is also required when, as a result of events changing the breakdown of voting rights, the percentage of the
voting rights attached to the voting securities reaches, exceeds or falls below the thresholds referred to in Paragraph (7)(a) above, even when no acquisition or disposal of securities has occurred (e.g., as a result of a capital increase or a
capital decrease of the Company). A disclosure is equally required when persons or legal entities enter into, modify or terminate an agreement of action in concert, when as result thereof, the percentage of the voting rights subject to the action in
concert or the percentage of the voting rights of one of the parties to the agreement of action in concert reaches, exceeds or falls below the thresholds referred to in Paragraph 7(a) above; 

(d) Disclosure statements referred to in this Paragraph (7) must be addressed to the Belgian Financial Services and Markets Authority
(whose offices are currently located Rue du Congrès 12-14, 1000 Brussels, Belgium) and to the board of directors of the Company at the latest the fourth trading day in Euronext Brussels following the day on which (i) the person or legal
entity is aware of the acquisition or the disposal or the possibility of exercising voting rights, or, having regard to the circumstances, should have been aware of it, regardless of the date on which the acquisition, disposal or possibility of
exercising voting rights takes effect, (ii) the person or legal entity is aware of the event changing the break down of voting rights, (iii) an agreement of action in concert is entered into, modified or terminated, or (iv) for
securities acquired by succession, the succession is accepted by the heirs, as the case may be, under the benefit of inventory (as such term is defined under Belgian law); 

(e) Unless otherwise provided by legal provisions in force, no one will be allowed to vote at a meeting of the holders of the Shares a number
of securities greater than the number validly disclosed, to the extent required, at the latest twenty (20) days before such meeting, in compliance with legal provisions in force and with the Articles of Association; and 

  
 A-7 








 (f) The disclosure requirements and limitations set out in Paragraphs (7) (a) to
(e) above are applicable to any Holder of ADSs and/or Beneficial Owner by reference to the number of both ADSs and Shares (that are not Deposited Securities) held by such Holder and/or beneficially owned by such Beneficial Owner. This Paragraph
(7) is a summary of the applicable provisions of Belgian law, as in effect as of the date of the Deposit Agreement, regarding disclosure of interests in the Company and shall not limit the obligations of Holders and Beneficial Owners to comply
with all relevant provisions of Belgian law, as applicable from time to time. Each Holder and Beneficial Owner shall be deemed to have authorized the Depositary and the Custodian to comply with any request from the Company or any competent authority
to disclose any information about any interest or any transaction of such Holder or Beneficial Owner in ADSs or Shares or Deposited Securities. 

(8) Liability for Taxes and Other Charges. Any tax or other governmental charge payable by the Custodian or by the Depositary
with respect to any Deposited Property, ADSs or this ADR shall be payable by the Holders and Beneficial Owners to the Depositary. The Company, the Custodian and/or the Depositary may withhold or deduct from any distributions made in respect of
Deposited Property and may sell for the account of a Holder and/or Beneficial Owner any or all of the Deposited Property and apply such distributions and sale proceeds in payment of any taxes (including applicable interest and penalties) or charges
that are or may be payable by Holders or Beneficial Owners in respect of the ADSs, Deposited Property and this ADR, the Holder and the Beneficial Owner hereof remaining liable for any deficiency. The Custodian may refuse the deposit of Shares and
the Depositary may refuse to issue ADSs, to deliver ADRs, register the transfer of ADSs, register the split-up or combination of ADRs and (subject to paragraph (25) of this ADR and Section 7.8 of the Deposit Agreement) the withdrawal of
Deposited Property until payment in full of such tax, charge, penalty or interest is received. Every Holder and Beneficial Owner agrees to indemnify the Depositary, the Company, the Custodian, and any of their agents, officers, employees and
Affiliates for, and to hold each of them harmless from, any claims with respect to taxes (including applicable interest and penalties thereon) arising from any tax benefit obtained for such Holder and/or Beneficial Owner. 

(9) Representations and Warranties on Deposit of Shares. Each person depositing Shares under the Deposit Agreement shall be
deemed thereby to represent and warrant that (i) such Shares and the certificates therefor are duly authorized, validly issued, fully paid, non-assessable and legally obtained by such person, (ii) all preemptive (and similar) rights, if
any, with respect to such Shares have been validly waived or exercised, (iii) the person making such deposit is duly authorized so to do, (iv) the Shares presented for deposit are free and clear of any lien, encumbrance, security interest,
charge, mortgage or adverse claim, (v) the Shares presented for deposit are not, and the ADSs issuable upon such deposit will not be, Restricted Securities (except as contemplated in Section 2.14 of the Deposit Agreement), (vi) the
Shares presented for deposit have not been stripped of any rights or entitlements and (vii) the deposit of the Shares do not violate any provisions of Belgian law. Such representations and warranties shall survive the deposit and withdrawal of
Shares, the issuance and cancellation of ADSs in respect thereof and the transfer of such ADSs. If any such representations or warranties are false in any way, the Company and the Depositary shall be authorized, at the cost and expense of the person
depositing Shares, to take any and all actions necessary to correct the consequences thereof. 

  
 A-8

deposit, such information relating to the registration on the books of the Company as the Depositary or the Custodian may deem necessary or proper or as the Company may reasonably require by written request to the Depositary consistent with its
obligations under the Deposit Agreement and this ADR. The Depositary and the Registrar, as applicable, may, and at the reasonable request of the Company, shall, to the extent practicable, withhold the execution or delivery or registration of
transfer of any ADR or ADS or the distribution or sale of any dividend or distribution of rights or of the proceeds thereof or, to the extent not limited by paragraph (25) and Section 7.8 of the Deposit Agreement, the delivery of any

limitations contained in the Deposit Agreement and in this ADR, it is a condition of this ADR, and every successive Holder of this ADR by accepting or holding the same consents and agrees, that title to this ADR (and to each Certificated ADS
evidenced hereby) shall be transferable upon the same terms as a certificated security under the laws of the State of New York, provided that, in the case of Certificated ADSs, this ADR has been properly endorsed or is accompanied by proper
instruments of transfer. Notwithstanding any notice to the contrary, the Depositary and the Company may deem and treat the Holder of this ADR (that is, the person in whose name this ADR is registered on the books of the Depositary) as the absolute
owner thereof for all purposes. Neither the Depositary nor the Company shall have any obligation nor be subject to any liability under the Deposit Agreement or this ADR to any holder of this ADR or any Beneficial Owner unless, in the case of a
holder of ADSs, such holder is the Holder of this ADR registered on the books of the Depositary or, in the case of a Beneficial Owner, such Beneficial Owner, or the Beneficial Owner’s representative, is the Holder registered on the books of the
Depositary. 
 (13) Validity of ADR. The Holder(s) of this ADR (and the ADSs represented hereby) shall not be entitled to any
benefits under the Deposit Agreement or be valid or enforceable for any purpose against the Depositary or the Company unless this ADR has been (i) dated, (ii) signed by the manual or facsimile signature of a duly-authorized signatory of
the Depositary, (iii) countersigned by the manual or facsimile signature of a duly-authorized signatory of the Registrar, and (iv) registered in the books maintained by the Registrar for the registration of issuances and transfers of ADRs.
An ADR bearing the facsimile signature of a duly-authorized signatory of the Depositary or the Registrar, who at the time of signature was a duly authorized signatory of the Depositary or the Registrar, as the case may be, shall bind the Depositary,
notwithstanding the fact that such signatory has ceased to be so authorized prior to the delivery of such ADR by the Depositary.

Available Information; Reports; Inspection of Transfer Books. The Company is subject to the periodic reporting requirements of the Exchange Act and, accordingly, is required to file or submit certain reports with the Commission. These
reports can be retrieved from the Commission’s website (www.sec.gov) and can be inspected and copied at the public reference facilities maintained by the Commission located (as of the date of the Deposit Agreement) at 100 F Street, N.E.,
Washington D.C. 20549. The Depositary shall make available for inspection by Holders at its Principal Office, as promptly as practicable after receipt thereof, any reports and communications, including any proxy soliciting materials, received from
the Company which are both (a) received by the Depositary, the Custodian, or the nominee of either of them as the holder of the Deposited Property and (b) made generally available to the holders of such Deposited Property by the
Company. 

  
 A-12 








 The Registrar shall keep books for the registration of ADSs which at all reasonable times shall
be open for inspection by the Company and by the Holders of such ADSs, provided that such inspection shall not be, to the Registrar’s knowledge, for the purpose of communicating with Holders of such ADSs in the interest of a business or object
other than the business of the Company or other than a matter related to the Deposit Agreement or the ADSs. 
 The Registrar may close the
transfer books with respect to the ADSs, at any time or from time to time, when deemed necessary or advisable by it in good faith in connection with the performance of its duties hereunder, or at the reasonable written request of the Company
subject, in all cases, to paragraph (25) and Section 7.8 of the Deposit Agreement.

 [FORM OF REVERSE OF ADR] 

SUMMARY OF CERTAIN ADDITIONAL PROVISIONS 

OF THE DEPOSIT AGREEMENT 

(15) Dividends and Distributions in Cash, Shares, etc. Whenever the Company intends to make a distribution of a cash dividend or
other cash distribution in respect of any Deposited Securities, the Company shall give notice thereof to the Depositary at least twenty (20) days prior to the proposed distribution specifying, inter alia, the record date
applicable for determining the holders of Deposited Securities entitled to receive such distribution. Upon the timely receipt of such notice, the Depositary shall establish an ADS Record Date upon the terms described in Section 4.9 of the
Deposit Agreement. Upon receipt of confirmation from the Custodian of the receipt of any cash dividend or other cash distribution on any Deposited Securities, or upon receipt of proceeds from the sale of any Deposited Property held in respect of the
ADSs under the terms of the Deposit Agreement, the Depositary will (i) if at the time of receipt thereof any amounts received in a Foreign Currency can, in the judgment of the Depositary (pursuant to Section 4.8 of the Deposit Agreement),
be converted on a practicable basis into Dollars transferable to the United States, promptly convert or cause to be converted such cash dividend, distribution or proceeds into Dollars (on the terms described in Section 4.8 of the Deposit
Agreement), (ii) if applicable and unless previously established, establish the ADS Record Date upon the terms described in Section 4.9 of the Deposit Agreement, and (iii) distribute promptly the amount thus received (net of
(a) the applicable fees and charges of, and expenses incurred by, the Depositary and (b) taxes required to be withheld as a result of the distribution) to the Holders entitled thereto as of the ADS Record Date in proportion to the number
of ADSs held as of the ADS Record Date. The Depositary shall distribute only such amount, however, as can be distributed without attributing to any Holder a fraction of one cent, and any balance not so distributed shall be held by the Depositary
(without liability for interest thereon) and shall be added to and become part of the next sum received by the Depositary for distribution to Holders of ADSs outstanding at the time of the next distribution. If the Company, the Custodian or the
Depositary is required to withhold and does withhold from any cash dividend or other cash distribution in respect of any Deposited Securities, or from any cash proceeds from the sales of Deposited Property, an amount on account of taxes, duties or
other governmental charges, the amount distributed to Holders on the ADSs shall be reduced accordingly. Such withheld amounts shall be forwarded by the Company, the Custodian or the Depositary to the relevant governmental authority. Evidence of
payment thereof by the Company shall be forwarded by the Company to the Depositary upon request. The Depositary will hold any cash amounts it is unable to distribute in a non-interest bearing account for the benefit of the applicable Holders and
Beneficial Owners of ADSs until the distribution can be effected or the funds that the Depositary holds must be escheated as unclaimed property in accordance with the laws of the relevant states of the United States. Notwithstanding anything
contained in the Deposit Agreement to the contrary, in the event the Company fails to give the Depositary timely notice of the proposed distribution provided for in Section 4.1 of the Deposit Agreement, the Depositary agrees to use commercially
reasonable efforts to perform the actions 

  
 A-14 








 
contemplated in Section 4.1 of the Deposit Agreement, and the Company, the Holders and the Beneficial Owners acknowledge that the Depositary shall have no liability for the Depositary’s
failure to perform the actions contemplated in Section 4.1 of the Deposit Agreement where such notice has not been so timely given, other than its failure to use commercially reasonable efforts, as provided herein. 

Whenever the Company intends to make a distribution that consists of a dividend in, or free distribution of, Shares, the Company shall give
notice thereof to the Depositary at least twenty (20) days prior to the proposed distribution, specifying, inter alia, the record date applicable to holders of Deposited Securities entitled to receive such distribution.
Upon the timely receipt of such notice from the Company, the Depositary shall establish the ADS Record Date upon the terms described in Section 4.9 of the Deposit Agreement. Upon receipt of confirmation from the Custodian of the receipt of
Shares so distributed by the Company, the Depositary shall either (i) subject to Section 5.9 of the Deposit Agreement, distribute to the Holders as of the ADS Record Date in proportion to the number of ADSs held as of the ADS Record Date,
additional ADSs, which represent in the aggregate the number of Shares received as such dividend, or free distribution, subject to the other terms of the Deposit Agreement (including, without limitation, (a) the applicable fees and charges of,
and expenses incurred by, the Depositary and (b) taxes), or (ii) if additional ADSs are not so distributed, take all actions necessary so that each ADS issued and outstanding after the ADS Record Date shall, to the extent permissible by
law, thenceforth also represent rights and interests in the additional integral number of Shares distributed upon the Deposited Securities represented thereby (net of (a) the applicable fees and charges of, and expenses incurred by, the
Depositary, and (b) taxes). In lieu of delivering fractional ADSs, the Depositary shall sell the number of Shares or ADSs, as the case may be, represented by the aggregate of such fractions and distribute the net proceeds upon the terms
described in Section 4.1 of the Deposit Agreement. 
 In the event that the Depositary determines that any distribution in property
(including Shares) is subject to any tax or other governmental charges which the Depositary is obligated to withhold, or, if the Company in the fulfillment of its obligations under Section 5.7 of the Deposit Agreement, has furnished an opinion
of U.S. counsel determining that Shares must be registered under the Securities Act or other laws in order to be distributed to Holders (and no such registration statement has been declared effective), the Depositary may, after consultation with the
Company to the extent reasonably practicable, dispose of all or a portion of such property (including Shares and rights to subscribe therefor) in such amounts and in such manner, including by public or private sale, as the Depositary deems necessary
and practicable, and the Depositary shall distribute the net proceeds of any such sale (after deduction of (a) taxes and (b) fees and charges of, and the expenses incurred by, the Depositary) to Holders entitled thereto upon the terms of
Section 4.1 of the Deposit Agreement. The Depositary shall hold and/or distribute any unsold balance of such property in accordance with the provisions of the Deposit Agreement. Notwithstanding anything contained in the Deposit Agreement to the
contrary, in the event the Company fails to give the Depositary timely notice of the proposed distribution provided for in Section 4.2 of the Deposit Agreement, the Depositary agrees to use commercially reasonable efforts to perform the actions
contemplated in Section 4.2 of the Deposit Agreement, and the Company, the Holders and the Beneficial Owners acknowledge that the Depositary shall 

  
 A-15 








 
have no liability for the Depositary’s failure to perform the actions contemplated in Section 4.2 of the Deposit Agreement where such notice has not been so timely given, other than its
failure to use commercially reasonable efforts, as provided herein. 
 Whenever the Company intends to make a distribution payable at the
election of the holders of Deposited Securities in cash or in additional Shares, the Company shall give notice thereof to the Depositary at least forty-five (45) days prior to the proposed distribution specifying, inter
alia, the record date applicable to holders of Deposited Securities entitled to receive such elective distribution and whether or not it wishes such elective distribution to be made available to Holders of ADSs. Upon the timely receipt of
a notice indicating that the Company wishes such elective distribution to be made available to Holders of ADSs, the Depositary shall consult with the Company to determine, and the Company shall assist the Depositary in its determination, whether it
is lawful and reasonably practicable to make such elective distribution available to the Holders of ADSs. The Depositary shall make such elective distribution available to Holders only if (i) the Company shall have timely requested that the
elective distribution be made available to Holders, (ii) the Depositary shall have determined that such distribution is reasonably practicable and (iii) the Depositary shall have received satisfactory documentation within the terms of
Section 5.7 of the Deposit Agreement. If the above conditions are not satisfied, the Depositary shall establish an ADS Record Date on the terms described in Section 4.9 of the Deposit Agreement and, to the extent permitted by law,
distribute to the Holders, on the basis of the same determination as is made in the Kingdom of Belgium in respect of the Shares for which no election is made, either (X) cash upon the terms described in Section 4.1 of the Deposit Agreement
or (Y) additional ADSs representing such additional Shares upon the terms described in Section 4.2 of the Deposit Agreement. If the above conditions are satisfied, the Depositary shall establish an ADS Record Date on the terms described in
Section 4.9 of the Deposit Agreement and establish procedures to enable Holders to elect the receipt of the proposed distribution in cash or in additional ADSs. The Company shall assist the Depositary in establishing such procedures to the
extent necessary. If a Holder elects to receive the proposed distribution (X) in cash, the distribution shall be made upon the terms described in Section 4.1 of the Deposit Agreement, or (Y) in ADSs, the distribution shall be made
upon the terms described in Section 4.2 of the Deposit Agreement. Nothing herein or in the Deposit Agreement shall obligate the Depositary to make available to the Holder a method to receive the elective distribution in Shares (rather than
ADSs). There can be no assurance that the Holder generally, or any Holder in particular, will be given the opportunity to receive elective distributions on the same terms and conditions as the holders of Shares. Notwithstanding anything contained in
the Deposit Agreement to the contrary, in the event the Company fails to give the Depositary timely notice of the proposed distribution provided for in Section 4.3 of the Deposit Agreement, the Depositary agrees to use commercially reasonable
efforts to perform the actions contemplated in Section 4.3 of the Deposit Agreement, and the Company, the Holders and the Beneficial Owners acknowledge that the Depositary shall have no liability for the Depositary’s failure to perform the
actions contemplated in Section 4.3 of the Deposit Agreement where such notice has not been so timely given, other than its failure to use commercially reasonable efforts, as provided herein. 

  
 A-16 








 Whenever the Company intends to offer, distribute, or cause to be offered or distributed to the
holders of the Deposited Securities rights to subscribe for additional Shares, the Company shall give notice thereof to the Depositary at least forty-five (45) days prior to the proposed offer specifying, inter alia, the
record date applicable to holders of Deposited Securities entitled to receive such rights and whether or not it wishes such rights to be made available to Holders of ADSs. Upon the timely receipt of a notice indicating that the Company wishes such
rights to be made available to Holders of ADSs, the Depositary shall consult with the Company to determine, and the Company shall assist the Depositary in its determination, whether it is lawful and reasonably practicable to make such rights
available to the Holders. The Depositary shall make such rights available to Holders only if (i) the Company shall have timely requested that such rights be made available to Holders, (ii) the Depositary shall have received satisfactory
documentation within the terms of Section 5.7 of the Deposit Agreement in the Deposit Agreement, and (iii) the Depositary shall have determined that such distribution of rights is reasonably practicable. In the event any of the conditions
set forth above are not satisfied or if the Company requests that the rights not be made available to Holders of ADSs, the Depositary shall proceed with the sale of the rights as contemplated in Section 4.4(b) of the Deposit Agreement. In the
event all conditions set forth above are satisfied, the Depositary shall establish an ADS Record Date (upon the terms described in Section 4.9 of the Deposit Agreement) and establish procedures to (x) distribute rights to purchase
additional ADSs (by means of warrants or otherwise), (y) to enable the Holders to exercise such rights (upon payment of the subscription price and of the applicable (a) fees and charges of, and expenses incurred by, the Depositary and
(b) taxes), and (z) to deliver ADSs upon the valid exercise of such rights. The Company shall assist the Depositary to the extent necessary in establishing such procedures. Nothing herein shall obligate the Depositary to make available to
the Holders a method to exercise rights to subscribe for Shares (rather than ADSs). If (i) the Company does not timely request the Depositary to make the rights available to Holders or requests that the rights not be made available to Holders,
(ii) the Depositary fails to receive satisfactory documentation within the terms of Section 5,7 of the Deposit Agreement or determines it is not reasonably practicable to make the rights available to Holders, or (iii) any rights made
available are not exercised and appear to be about to lapse, the Depositary shall determine whether it is lawful and reasonably practicable to sell such rights, in a riskless principal capacity, at such place and upon such terms (including public
and private sale) as it may deem practicable. The Company shall assist the Depositary to the extent necessary to determine such legality and practicability. The Depositary shall, upon such sale, convert and distribute proceeds of such sale (net of
applicable (a) fees and charges of, and expenses incurred by, the Depositary and (b) taxes) upon the terms hereof and of Section 4.1 of the Deposit Agreement. If the Depositary is unable to make any rights available to Holders upon
the terms described in Section 4.4(a) of the Deposit Agreement or to arrange for the sale of the rights upon the terms described in Section 4.4(b) of the Deposit Agreement, the Depositary shall allow such rights to lapse. The Depositary
shall not be responsible for (i) any failure to determine that it may be lawful or practicable to make such rights available to Holders in general or any Holders in particular, (ii) any foreign exchange exposure or loss incurred in
connection with such sale or exercise, or (iii) the content of any materials forwarded to the Holders on behalf of the Company in connection with the rights distribution. 

  
 A-17 








 Notwithstanding anything herein or in the Deposit Agreement to the contrary, if registration
(under the Securities Act or any other applicable law) of the rights or the securities to which any rights relate may be required in order for the Company to offer such rights or such securities to Holders and to sell the securities represented by
such rights, the Depositary will not distribute such rights to the Holders (i) unless and until a registration statement under the Securities Act (or other applicable law) covering such offering is in effect or (ii) unless the Company
furnishes the Depositary opinion(s) of counsel for the Company in the United States and counsel to the Company in any other applicable country in which rights would be distributed, in each case reasonably satisfactory to the Depositary, to the
effect that the offering and sale of such securities to Holders and Beneficial Owners are exempt from, or do not require registration under, the provisions of the Securities Act or any other applicable laws. In the event that the Company, the
Depositary or the Custodian shall be required to withhold and does withhold from any distribution of Deposited Property (including rights) an amount on account of taxes or other governmental charges, the amount distributed to the Holders of ADSs
shall be reduced accordingly. In the event that the Depositary determines that any distribution of Deposited Property (including Shares and rights to subscribe therefor) is subject to any tax or other governmental charges which the Depositary is
obligated to withhold, the Depositary may dispose of all or a portion of such Deposited Property (including Shares and rights to subscribe therefor) in such amounts and in such manner, including by public or private sale, as the Depositary deems
necessary and practicable to pay any such taxes or charges. 
 There can be no assurance that Holders generally, or any Holder in
particular, will be given the opportunity to receive or exercise rights on the same terms and conditions as the holders of Shares or be able to exercise such rights. Nothing herein or in the Deposit Agreement shall obligate the Company to file any
registration statement in respect of any rights or Shares or other securities to be acquired upon the exercise of such rights. 
 Whenever
the Company intends to distribute to the holders of Deposited Securities property other than cash, Shares or rights to purchase additional Shares, the Company shall give timely notice thereof to the Depositary and shall indicate whether or not it
wishes such distribution to be made to Holders of ADSs. Upon receipt of a notice indicating that the Company wishes such distribution be made to Holders of ADSs, the Depositary shall consult with the Company, and the Company shall assist the
Depositary, to determine whether such distribution to Holders is lawful and reasonably practicable. The Depositary shall not make such distribution unless (i) the Company shall have requested the Depositary to make such distribution to Holders,
(ii) the Depositary shall have received satisfactory documentation within the terms of Section 5.7 of the Deposit Agreement, and (iii) the Depositary shall have determined that such distribution is reasonably practicable. 

Upon receipt of satisfactory documentation and the request of the Company to distribute property to Holders of ADSs and after making the
requisite determinations set forth in (a) above, the Depositary shall distribute the property so received to the Holders of record, as of the ADS Record Date, in proportion to the number of ADSs held by them respectively and in such manner as
the Depositary may deem practicable for accomplishing such distribution (i) upon receipt of payment or net of the applicable fees and charges of, and expenses incurred by, the Depositary, 

  
 A-18 








 and (ii) net of any taxes required to be withheld. The Depositary may dispose of all or a portion of the
property so distributed and deposited, in such amounts and in such manner (including public or private sale) as the Depositary may deem practicable or necessary to satisfy any taxes (including applicable interest and penalties) or other governmental
charges applicable to the distribution. 
 If (i) the Company does not request the Depositary to make such distribution to Holders or
requests not to make such distribution to Holders, (ii) the Depositary does not receive satisfactory documentation within the terms of Section 5.7 of the Deposit Agreement, or (iii) the Depositary determines that all or a portion of
such distribution is not reasonably practicable, the Depositary shall sell or cause such property to be sold in a public or private sale, at such place or places and upon such terms as it may deem practicable and shall (i) cause the proceeds of
such sale, if any, to be converted into Dollars and (ii) distribute the proceeds of such conversion received by the Depositary (net of applicable (a) fees and charges of, and expenses incurred by, the Depositary and (b) taxes) to the
Holders as of the ADS Record Date upon the terms of Section 4.1 of the Deposit Agreement. If the Depositary is unable to sell such property, the Depositary may dispose of such property for the account of the Holders in any way it deems
reasonably practicable under the circumstances. 
 Neither the Depositary nor the Company shall be responsible for (i) any failure to
determine whether it is lawful or practicable to make the property described in Section 4.5 of the Deposit Agreement available to Holders in general or any Holders in particular, nor (ii) any loss incurred in connection with the sale or
disposal of such property. 
 (16) Redemption. If the Company intends to exercise any right of redemption (by way of
shareholders resolution or otherwise) in respect of any of the Deposited Securities (where such Deposited Securities provide the Company with a right of redemption), the Company shall give notice thereof to the Depositary at least thirty
(30) days prior to the intended date of redemption which notice shall set forth the particulars of the proposed redemption. Upon timely receipt of (i) such notice and (ii) satisfactory documentation given by the Company to the
Depositary within the terms of Section 5.7 of the Deposit Agreement, and only if, after consultation between the Depositary and the Company, the Depositary shall have determined that such proposed redemption is practicable, the Depositary shall
provide to each Holder a notice setting forth the intended exercise by the Company of the redemption rights and any other particulars set forth in the Company’s notice to the Depositary. The Depositary shall instruct the Custodian to present to
the Company the Deposited Securities in respect of which redemption rights are being exercised against payment of the applicable redemption price. Upon receipt of confirmation from the Custodian that the redemption has taken place and that funds
representing the redemption price have been received, the Depositary shall convert, transfer, and distribute the proceeds (net of applicable (a) fees and charges of, and the expenses incurred by, the Depositary, and (b) taxes), retire ADSs
and cancel ADRs, if applicable, upon delivery of such ADSs by Holders thereof and the terms set forth in Sections 4.1 and 6.2 of the Deposit Agreement. If less than all outstanding Deposited Securities are redeemed, the ADSs to be retired
will be selected by lot or on a pro rata basis, as may be determined by the Depositary after consultation with the Company. The redemption price per ADS shall be the dollar equivalent of the per share amount


  
 A-19 








 received by the Depositary (adjusted to reflect the ADS(s)-to-Share(s) ratio) upon the redemption of the
Deposited Securities represented by ADSs (subject to the terms of Section 4.8 of the Deposit Agreement and the applicable fees and charges of, and expenses incurred by, the Depositary, and taxes) multiplied by the number of Deposited Securities
represented by each ADS redeemed. Notwithstanding anything contained in this Deposit Agreement to the contrary, in the event the Company fails to give the Depositary timely notice of the proposed redemption provided for in Section 4.7 of the
Deposit Agreement, the Depositary agrees to use commercially reasonable efforts to perform the actions contemplated in Section 4.7 of the Deposit Agreement, and the Company, the Holders and the Beneficial Owners acknowledge that the Depositary
shall have no liability for the Depositary’s failure to perform the actions contemplated in Section 4.7 of the Deposit Agreement where such notice has not been so timely given, other than its failure to use commercially reasonable efforts,
as provided herein. 
 (17) Fixing of ADS Record Date. Whenever the Depositary shall receive notice of the fixing of a record
date by the Company for the determination of holders of Deposited Securities entitled to receive any distribution (whether in cash, Shares, rights or other distribution), or whenever for any reason the Depositary causes a change in the number of
Shares that are represented by each ADS, or whenever the Depositary shall receive notice of any meeting of, or solicitation of consents or proxies of, holders of Shares or other Deposited Securities, or whenever the Depositary shall find it
necessary or convenient in connection with the giving of any notice, solicitation of any consent or any other matter, the Depositary shall, after consultation with the Company to the extent reasonably practicable, fix the record date (the
“ADS Record Date”) for the determination of the Holders of ADS(s) who shall be entitled to receive such distribution, to give instructions for the exercise of voting rights at any such meeting, to give or withhold such consent, to
receive such notice or solicitation or to otherwise take action, or to exercise the rights of Holders with respect to such changed number of Shares represented by each ADS. The Depositary shall make reasonable efforts to establish the ADS Record
Date as closely as possible to the applicable record date for the Deposited Securities (if any) set by the Company in the Kingdom of Belgium and shall not announce the establishment of any ADS Record Date prior to the relevant corporate action
having been made public by the Company (if such corporate action affects the Deposited Securities). Subject to applicable law, and the provisions of Sections 4.1 through 4.8 and to the other terms and conditions of the Deposit Agreement, only the
Holders of ADSs at the close of business in New York on such ADS Record Date shall be entitled to receive such distribution, to give such voting instructions, to receive such notice or solicitation, or otherwise take action. For the ADS Record Date
in respect of a shareholders meeting of the Company, such date shall be determined by the Depositary and the Company jointly, it being understood that such ADS Record Date shall not be established earlier than 30 days prior to the relevant
shareholders meeting. 
 (18) Voting of Deposited Securities. As soon as practicable after receipt of notice of any meeting at
which the holders of Deposited Securities are entitled to vote, or of solicitation of consents or proxies from holders of Deposited Securities, the Depositary shall fix the ADS Record Date in respect of such meeting or solicitation of consent or
proxy in accordance with Section 4.9 of the Deposit Agreement. The Depositary shall, as soon as practicable after receipt of notice of any meeting at which the holders of Deposited Securities are entitled to vote, or of


  
 A-20 








 solicitation of consents or proxies from holders of Deposited Securities, if requested by the Company in writing
in a timely manner, at the Company’s expense and provided no U.S. legal prohibitions exist, distribute to Holders as of the ADS Record Date: (a) such notice of meeting or solicitation of consent or proxy, (b) a statement that the
Holders at the close of business on the ADS Record Date and, if so required by the Company, who also hold the ADSs as of the applicable share record date, will be entitled, subject to any applicable law, the provisions of the Deposit Agreement, the
Articles of Association of the Company and the provisions of or governing the Deposited Securities (which provisions, if any, shall be summarized in pertinent part by the Company), to instruct the Depositary as to the exercise of the voting rights,
if any, pertaining to the Deposited Securities represented by such Holder’s ADSs, and (c) a brief statement as to the manner and timing in which such voting instructions may be given, including the following express indications:
(x) that no voting rights will be exercised by the Depositary if the Depositary does not receive voting instructions timely from a Holder; and (y) that the Depositary will deem a Holder (unless otherwise specified in the notice distributed
to the Holders) to have instructed the Depositary to vote in favor of the items set forth in such voting instructions if the Depositary has timely received the voting instructions from such Holder but if such Holder has failed to specify the manner
in which the Depositary is to vote the Deposited Securities represented by such Holder’s ADSs. 
 Notwithstanding anything contained in
the Deposit Agreement or any ADR, the Depositary may, to the extent not prohibited by law or regulations, or by the requirements of the stock exchange on which the ADSs are listed, and after consultation with the Company to the extent reasonably
practicable, in lieu of distribution of the materials provided to the Depositary in connection with any meeting of, or solicitation of consents or proxies from, holders of Deposited Securities, distribute to the Holders a notice that provides
Holders with, or otherwise publicizes to Holders, instructions on how to retrieve such materials or receive such materials upon request (i.e., by reference to a website containing the materials for retrieval or a contact for requesting copies
of the materials); provided, that, upon request of any Holder, the Depositary timely distributes to such Holder the materials provided to the Depositary in connection with any meeting of the holders of the Shares. 

Voting instructions may be given only in respect of a number of ADSs representing an integral number of Deposited Securities. Upon the timely
receipt from a Holder of ADSs as of the ADS Record Date (and, if so required by the Company, who also hold the ADSs as of the applicable share record date) of voting instructions in the manner specified by the Depositary, the Depositary shall
endeavor, insofar as practicable and permitted under applicable law, the provisions of the Deposit Agreement, Articles of Association of the Company and the provisions of the Deposited Securities, to vote, or cause the Custodian to vote, the
Deposited Securities (in person or by proxy) represented by such Holder’s ADSs in accordance with such voting instructions. The Depositary agrees not to vote, cause to be voted or attempt to exercise the right to vote that attaches to any
Deposited Securities, other than in accordance with valid voting instructions given or deemed given in compliance with this Section. 

Deposited Securities represented by ADSs for which no timely voting instructions are received by the Depositary from the Holder shall not be
voted (except as otherwise contemplated 

  
 A-21 








 herein). Neither the Depositary nor the Custodian shall under any circumstances exercise any discretion as to
voting and neither the Depositary nor the Custodian shall vote, attempt to exercise the right to vote, or in any way make use of, for purposes of establishing a quorum or otherwise, the Deposited Securities represented by ADSs, except pursuant to
and in accordance with the voting instructions timely received from Holders or as otherwise contemplated herein. If the Depositary timely receives voting instructions from a Holder which fail to specify the manner in which the Depositary is to vote
the Deposited Securities represented by such Holder’s ADSs, the Depositary will deem such Holder (unless otherwise specified in the notice distributed to Holders) to have instructed the Depositary to vote in favor of the items set forth in such
voting instructions. 
 The right of any Holder to give instructions to the Depositary as to the exercise of voting rights or the right of
any Holder to withdraw Deposited Securities in person or by proxy may be limited if such Holder fails to comply with the requirements described in Sections 3.4, 3.5, 3.6 and 3.7 of the Deposit Agreement. 

Notwithstanding anything else contained in the Deposit Agreement or any ADR, the Depositary shall not have any obligation to take any action
with respect to any meeting, or solicitation of consents or proxies, of holders of Deposited Securities if the taking of such action would violate U.S. laws. The Company agrees to take any and all actions reasonably necessary to enable Holders and
Beneficial Owners to exercise the voting rights accruing to the Deposited Securities and to deliver to the Depositary an opinion of U.S. counsel addressing any actions requested to be taken if so reasonably requested by the Depositary. 

There can be no assurance that Holders generally or any Holder in particular will receive the notice described above with sufficient time to
enable the Holder to return voting instructions to the Depositary, or otherwise take action, in a timely manner. 
 The Depositary agrees,
upon the request of Company, to provide to the Company copies of the voting instructions it receives (in the case of voting instructions received from Holders by any electronic means, a tabulation of such voting instructions) as promptly as
practicable, and at the latest six (6) business days prior to any upcoming meeting date, upon receipt thereof. 
 Holders who have
delivered voting instructions agree that such voting instruction may, at the request of the Company, be disclosed by the Company, for purposes of compliance with Belgian law, in connection with any meeting of the holders of the Shares, whether
prior, during or after such meeting. 
 Notwithstanding anything else contained in the Deposit Agreement or any Receipt to the contrary, and
to the extent not prohibited by law or regulations, the Depositary and the Company may, by agreement between them, with notice to the Holders, modify, amend or adopt additional voting procedures from time to time as they determine may be necessary
or appropriate (subject, in each case, to the terms of Sections 6.1 and 7.8 of the Deposit Agreement).

 (19) Changes Affecting Deposited Securities. Upon any split-up, cancellation, consolidation or any other reclassification of Deposited Securities, or upon any recapitalization, reorganization, merger, consolidation or sale of assets affecting the Company or to which it
is a party, any property which shall be received by the Depositary or the Custodian in exchange for, or in conversion of, or replacement of, or otherwise in respect of, such Deposited Securities shall, to the extent permitted by law, be treated as
new Deposited Property under the Deposit Agreement, and this ADR shall, subject to the provisions of the Deposit Agreement, this ADR evidencing such ADSs and applicable law, represent the right to receive such additional or replacement Deposited
Property. In giving effect to such split-up, cancellation, consolidation or other reclassification of Deposited Securities, recapitalization, reorganization, merger, consolidation or sale of assets, the Depositary may, with the Company’s
approval, and shall, if the Company shall so request, subject to the terms of the Deposit Agreement and receipt of an opinion of counsel to the Company reasonably satisfactory to the Depositary that such actions are not in violation of any
applicable laws or regulations, (i) issue and deliver additional ADSs as in the case of a stock dividend on the Shares, (ii) amend the Deposit Agreement and the applicable ADRs, (iii) amend the applicable Registration Statement(s) on
Form F-6 as filed with the Commission in respect of the ADSs, (iv) call for the surrender of outstanding ADRs to be exchanged for new ADRs, and (v) take such other actions as are appropriate to reflect the transaction with respect to the
ADSs. The Company agrees to, jointly with the Depositary, amend the Registration Statement on Form F-6 as filed with the Commission to permit the issuance of such new form of ADRs. Notwithstanding the foregoing, in the event that any Deposited
Property so received may not be lawfully distributed to some or all Holders, the Depositary may, with the Company’s approval, and shall, if the Company requests, subject to receipt of an opinion of Company’s counsel reasonably satisfactory
to the Depositary that such action is not in violation of any applicable laws or regulations, sell such Deposited Property at public or private sale, at such place or places and upon such terms as it may deem proper and may allocate the net proceeds
of such sales (net of (a) fees and charges of, and expenses incurred by, the Depositary and (b) applicable taxes) for the account of the Holders otherwise entitled to such Deposited Property upon an averaged or other practicable basis
without regard to any distinctions among such Holders and distribute the net proceeds so allocated to the extent practicable as in the case of a distribution received in cash pursuant to Section 4.1 of the Deposit Agreement. The Depositary
shall not be responsible for (i) any failure to determine that it may be lawful or practicable to make such Deposited Property available to Holders in general or to any Holder in particular, (ii) any foreign exchange exposure or loss
incurred in connection with such sale, or (iii) any liability to the purchaser of such Deposited Property. 
 (20)
Exoneration. Notwithstanding anything contained in the Deposit Agreement or any ADR, neither the Depositary nor the Company shall be obligated to do or perform any act which is inconsistent with the provisions of the Deposit Agreement or
incur any liability (i) if the Depositary or the Company shall be prevented or forbidden from, or delayed in, doing or performing any act or thing required by the terms of the Deposit Agreement and this ADR, by reason of any provision of any
present or future law or regulation of the United States, the 

  
 A-23 








 Kingdom of Belgium, or any other country, or of any other governmental authority or regulatory authority or stock
exchange, or on account of the possible criminal or civil penalties or restraint, or by reason of any provision, present or future, of the Articles of Association of the Company or any provision of or governing any Deposited Securities, or by reason
of any act of God or war or other circumstances beyond its control (including, without limitation, nationalization, expropriation, currency restrictions, work stoppage, strikes, civil unrest, acts of terrorism, revolutions, rebellions, explosions
and computer failure), (ii) by reason of any exercise of, or failure to exercise, any discretion provided for in the Deposit Agreement or in the Articles of Association of the Company or provisions of or governing Deposited Securities,
(iii) for any action or inaction in reliance upon the advice of or information from legal counsel, accountants, any person presenting Shares for deposit, any Holder, any Beneficial Owner or authorized representative thereof, or any other person
believed by it in good faith to be competent to give such advice or information, (iv) for the inability by a Holder or Beneficial Owner to benefit from any distribution, offering, right or other benefit which is made available to holders of
Deposited Securities but is not, under the terms of the Deposit Agreement, made available to Holders of ADSs, or (v) for any consequential or punitive damages (including lost profits) for any breach of the terms of the Deposit Agreement. The
Depositary, its controlling persons, its agents, any Custodian and the Company, its controlling persons and its agents may rely and shall be protected in acting upon any written notice, request or other document believed by it to be genuine and to
have been signed or presented by the proper party or parties. No disclaimer of liability under the Securities Act is intended by any provision of the Deposit Agreement or this ADR. 

(21) Standard of Care. The Company and the Depositary assume no obligation and shall not be subject to any liability under the
Deposit Agreement or this ADR to any Holder(s) or Beneficial Owner(s), except that the Company and the Depositary agree to perform their respective obligations specifically set forth in the Deposit Agreement or this ADR without negligence or bad
faith. Without limitation of the foregoing, neither the Depositary, nor the Company, nor any of their respective controlling persons, or agents, shall be under any obligation to appear in, prosecute or defend any action, suit or other proceeding in
respect of any Deposited Property or in respect of the ADSs, which in its reasonable opinion may involve it in expense or liability, unless indemnity satisfactory to it against all expense (including fees and disbursements of counsel) and liability
be furnished as often as may be required (and no Custodian shall be under any obligation whatsoever with respect to such proceedings, the responsibility of the Custodian being solely to the Depositary). 

The Depositary and its agents shall not be liable for any failure to carry out any instructions to vote any of the Deposited Securities, or
for the manner in which any vote is cast or the effect of any vote, provided that any such action or omission is in good faith, without negligence and in accordance with the terms of the Deposit Agreement. The Depositary shall not incur any
liability for any failure to determine that any distribution or action may be lawful or reasonably practicable, for the content of any information submitted to it by the Company for distribution to the Holders or for any inaccuracy of any
translation thereof, for any investment risk associated with acquiring an interest in the Deposited Property, for the validity or worth of the Deposited Property or for any tax consequences that may result from the ownership of ADSs,


  
 A-24 








 Shares or other Deposited Property, for the credit-worthiness of any
third party, for allowing any rights to lapse upon the terms of the Deposit Agreement, for the failure or timeliness of any notice from the Company, or for any action of or failure to act by, or any information provided or not provided by, DTC or
any DTC Participant. 
 The Depositary shall not be liable for any acts or omissions made by a successor depositary whether in connection
with a previous act or omission of the Depositary or in connection with any matter arising wholly after the removal or resignation of the Depositary, provided that in connection with the issue out of which such potential liability arises the
Depositary performed its obligations without negligence or bad faith while it acted as Depositary. 
 (22) Resignation and Removal of
the Depositary; Appointment of Successor Depositary. The Depositary may at any time resign as Depositary under the Deposit Agreement by written notice of resignation delivered to the Company, such resignation to be effective on the earlier
of (i) the 90th day after delivery thereof to the Company (whereupon the Depositary shall be entitled to take the actions contemplated in Section 6.2 of the Deposit Agreement), or (ii) the appointment by the Company of a successor
depositary and its acceptance of such appointment as provided in the Deposit Agreement. The Depositary may at any time be removed by the Company by written notice of such removal, which removal shall be effective on the later of (i) the 90th
day after delivery thereof to the Depositary (whereupon the Depositary shall be entitled to take the actions contemplated in Section 6.2 of the Deposit Agreement), or (ii) the appointment by the Company of a successor depositary and its
acceptance of such appointment by the Company as provided in the Deposit Agreement. In case at any time the Depositary acting hereunder shall resign or be removed, the Company shall use its reasonable best efforts to appoint a successor depositary,
which shall be a bank or trust company having an office in the Borough of Manhattan, the City of New York. Every successor depositary shall be required by the Company to execute and deliver to its predecessor and to the Company an instrument in
writing accepting its appointment hereunder, and thereupon such successor depositary, without any further act or deed (except as required by applicable law), shall become fully vested with all the rights, powers, duties and obligations of its
predecessor (other than as contemplated in Sections 5.8 and 5.9 of the Deposit Agreement). The predecessor depositary, upon payment of all sums due it and on the written request of the Company, shall (i) execute and deliver an instrument
transferring to such successor all rights and powers of such predecessor hereunder (other than as contemplated in Sections 5.8 and 5.9 of the Deposit Agreement), (ii) duly assign, transfer and deliver all of the Depositary’s right, title
and interest to the Deposited Property to such successor, and (iii) deliver to such successor a list of the Holders of all outstanding ADSs and such other information relating to ADSs and Holders thereof as the successor may reasonably request.
Any such successor depositary shall promptly provide notice of its appointment to such Holders. Any entity into or with which the Depositary may be merged or consolidated shall be the successor of the Depositary without the execution or filing of
any document or any further act. 

  
 A-25 








 (23) Amendment/Supplement. Subject to the terms and conditions of this paragraph
23, and Section 6.1 of the Deposit Agreement and applicable law, this ADR and any provisions of the Deposit Agreement may at any time and from time to time be amended or supplemented by written agreement between the Company and the Depositary
in any respect which they may deem necessary or desirable without the prior written consent of the Holders or Beneficial Owners. Any amendment or supplement which shall impose or increase any fees or charges (other than charges in connection with
foreign exchange control regulations, and taxes and other governmental charges, delivery and other such expenses), or which shall otherwise materially prejudice any substantial existing right of Holders or Beneficial Owners, shall not, however,
become effective as to outstanding ADSs until the expiration of thirty (30) days after notice of such amendment or supplement shall have been given to the Holders of outstanding ADSs. Notice of any amendment to the Deposit Agreement or any ADR
shall not need to describe in detail the specific amendments effectuated thereby, and failure to describe the specific amendments in any such notice shall not render such notice invalid, provided, however, that, in each such case, the
notice given to the Holders identifies a means for Holders and Beneficial Owners to retrieve or receive the text of such amendment (i.e., upon retrieval from the Commission’s, the Depositary’s or the Company’s website or upon
request from the Depositary). The parties hereto agree that any amendments or supplements which (i) are reasonably necessary (as agreed by the Company and the Depositary) in order for (a) the ADSs to be registered on Form F-6 under the
Securities Act or (b) the ADSs to be settled solely in electronic book-entry form and (ii) do not in either such case impose or increase any fees or charges to be borne by Holders, shall be deemed not to materially prejudice any
substantial rights of Holders or Beneficial Owners. Every Holder and Beneficial Owner at the time any amendment or supplement so becomes effective shall be deemed, by continuing to hold such ADSs, to consent and agree to such amendment or supplement
and to be bound by the Deposit Agreement and this ADR, if applicable, as amended or supplemented thereby. In no event shall any amendment or supplement impair the right of the Holder to surrender such ADS and receive therefor the Deposited
Securities represented thereby, except in order to comply with mandatory provisions of applicable law. Notwithstanding the foregoing, if any governmental body should adopt new laws, rules or regulations which would require an amendment of, or
supplement to, the Deposit Agreement to ensure compliance therewith, the Company and the Depositary may amend or supplement the Deposit Agreement and this ADR at any time in accordance with such changed laws, rules or regulations. Such amendment or
supplement to the Deposit Agreement and this ADR, if applicable, in such circumstances may become effective before a notice of such amendment or supplement is given to Holders or within any other period of time as required for compliance with such
laws, rules or regulations. 
 (24) Termination. The Depositary shall, at any time at the written direction of the Company,
terminate the Deposit Agreement by distributing notice of such termination to the Holders of all ADSs then outstanding at least thirty (30) days prior to the date fixed in such notice for such termination. If ninety (90) days shall have
expired after (i) the Depositary shall have delivered to the Company a written notice of its election to resign, or (ii) the Company shall have delivered to the Depositary a written notice of the removal of the Depositary, and, in either
case, a successor depositary shall not have been appointed and accepted its appointment as 

  
 A-26 








 provided in Section 5.4 of the Deposit Agreement, the Depositary may terminate the Deposit Agreement by
distributing notice of such termination to the Holders of all ADSs then outstanding at least thirty (30) days prior to the date fixed in such notice for such termination. The date so fixed for termination of the Deposit Agreement in any
termination notice so distributed by the Depositary to the Holders of ADSs is referred to as the “Termination Date”. Until the Termination Date, the Depositary shall continue to perform all of its obligations under the Deposit
Agreement, and the Holders and Beneficial Owners will be entitled to all of their rights under the Deposit Agreement. If any ADSs shall remain outstanding after the Termination Date, the Registrar and the Depositary shall not, after the Termination
Date, have any obligation to perform any further acts under the Deposit Agreement, except that the Depositary shall, subject, in each case, to the terms and conditions of the Deposit Agreement, continue to (i) collect dividends and other
distributions pertaining to Deposited Securities, (ii) sell Deposited Property received in respect of Deposited Securities, (iii) deliver Deposited Securities, together with any dividends or other distributions received with respect
thereto and the net proceeds of the sale of any other Deposited Property, in exchange for ADSs surrendered to the Depositary (after deducting, or charging, as the case may be, in each case, the fees and charges of, and expenses incurred by, the
Depositary, and all applicable taxes or governmental charges for the account of the Holders and Beneficial Owners, in each case upon the terms set forth in Section 5.9 of the Deposit Agreement), and (iv) take such actions as may be
required under applicable law in connection with its role as Depositary under the Deposit Agreement. At any time after the Termination Date, the Depositary may sell the Deposited Property then held under the Deposit Agreement and shall after such
sale hold un-invested the net proceeds of such sale, together with any other cash then held by it under the Deposit Agreement, in an un-segregated account and without liability for interest, for the pro rata benefit of the Holders whose ADSs have
not theretofore been surrendered. After making such sale, the Depositary shall be discharged from all obligations under the Deposit Agreement except (i) to account for such net proceeds and other cash (after deducting, or charging, as the case
may be, in each case, the fees and charges of, and expenses incurred by, the Depositary, and all applicable taxes or governmental charges for the account of the Holders and Beneficial Owners, in each case upon the terms set forth in Section 5.9
of the Deposit Agreement), and (ii) as may be required at law in connection with the termination of the Deposit Agreement. After the Termination Date, the Company shall be discharged from all obligations under the Deposit Agreement, except for
its obligations to the Depositary under Sections 5.8, 5.9 and 7.6 of the Deposit Agreement. The obligations under the terms of the Deposit Agreement of Holders and Beneficial Owners of ADSs outstanding as of the Termination Date shall survive the
Termination Date and shall be discharged only when the applicable ADSs are presented by their Holders to the Depositary for cancellation under the terms of the Deposit Agreement. 

(25) Compliance with U.S. Securities Laws. Notwithstanding any provisions in this ADR or the Deposit Agreement to the contrary,
the withdrawal or delivery of Deposited Securities will not be suspended by the Company or the Depositary except as would be permitted by Instruction I.A.(1) of the General Instructions to the Form F-6 Registration Statement, as amended from time to
time, under the Securities Act. 

  
 A-27 








 (26) Certain Rights of the Depositary; Limitations. Subject to the further terms
and provisions of this paragraph (26) and Section 5.10 of the Deposit Agreement and subject to any applicable securities laws and regulations (including without limitation any insider dealing restrictions), the Depositary, its Affiliates
and their agents, on their own behalf, may own and deal in any class of securities of the Company and its Affiliates and in ADSs. In its capacity as Depositary, the Depositary shall not lend Shares or ADSs; provided, however, that the
Depositary may (i) issue ADSs prior to the receipt of Shares pursuant to Section 2.3 of the Deposit Agreement and (ii) deliver Shares prior to the receipt of ADSs for withdrawal of Deposited Securities pursuant to Section 2.7 of
the Deposit Agreement, including ADSs which were issued under (i) above but for which Shares may not have been received (each such transaction a “Pre-Release Transaction”). The Depositary may receive ADSs in lieu of Shares
under (i) above and receive Shares in lieu of ADSs under (ii) above. Each such Pre-Release Transaction will be (a) subject to a written agreement whereby the person or entity (the “Applicant”) to whom ADSs or Shares
are to be delivered (w) represents that at the time of the Pre-Release Transaction the Applicant or its customer owns the Shares or ADSs that are to be delivered by the Applicant under such Pre-Release Transaction, (x) agrees to indicate
the Depositary as owner of such Shares or ADSs in its records and to hold such Shares or ADSs in trust for the Depositary until such Shares or ADSs are delivered to the Depositary or the Custodian, (y) unconditionally guarantees to deliver to
the Depositary or the Custodian, as applicable, such Shares or ADSs and (z) agrees to any additional restrictions or requirements that the Depositary deems appropriate, (b) at all times fully collateralized with cash, U.S. government
securities or such other collateral as the Depositary deems appropriate, (c) terminable by the Depositary on not more than five (5) business days’ notice and (d) subject to such further indemnities and credit regulations as the
Depositary deems appropriate. The Depositary will normally limit the number of ADSs and Shares involved in such Pre-Release Transactions at any one time to thirty percent (30%) of the ADSs outstanding (without giving effect to ADSs outstanding
under (i) above), provided, however, that the Depositary reserves the right to change or disregard such limit from time to time as it deems appropriate. The Depositary may also set limits with respect to the number of ADSs and
Shares involved in Pre-Release Transactions with any one person on a case-by-case basis as it deems appropriate. The Depositary may retain for its own account any compensation received by it in conjunction
with the foregoing. Collateral provided pursuant to (b) above, but not the earnings thereon, shall be held for the benefit of the Holders (other than the Applicant). 

(27) Governing Law and Jurisdiction. The Deposit Agreement and the ADRs shall be interpreted in accordance with, and all rights
hereunder and thereunder and provisions hereof and thereof shall be governed by, the laws of the State of New York applicable to contracts made and to be wholly performed in that State. Notwithstanding anything contained in the Deposit Agreement,
any ADR or any present or future provisions of the laws of the State of New York, the rights of holders of Shares and of any other Deposited Securities and the obligations and duties of the Company in respect of the holders of Shares and other
Deposited Securities, as such, shall be governed by the laws of the Kingdom of Belgium (or, if applicable, such other laws as may govern the Deposited Securities).

 Legends 

The ADRs issued in respect of Partial Entitlement American Depositary Shares shall bear the following legend on the face of the ADR: “This ADR evidences
ADSs representing ‘partial entitlement’ Shares of [Company] and as such do not entitle the holders thereof to the same per-share entitlement as other Shares (which are ‘full entitlement’ Shares) issued and outstanding at such
