No Receipt shall be entitled to any benefits under this Deposit Agreement or be valid or obligatory for any purpose, unless such Receipt shall have been (i) executed by the Depositary by the manual signature of a duly authorized officer of the Depositary or (ii) executed by the facsimile signature of a duly authorized officer of the Depositary and countersigned by the manual signature of a duly authorized signatory of the Depositary or a Registrar. The Depositary shall maintain books on which (x) each Receipt so executed and delivered as hereinafter provided and the transfer of each such Receipt shall be registered and (y) all American Depositary Shares delivered as hereinafter provided and all registrations of transfer of American Depositary Shares shall be registered. A Receipt bearing the facsimile signature of a person that was at any time a proper officer of the Depositary shall, subject to the other provisions of this paragraph, bind the Depositary, notwithstanding that such person was not a proper officer of the Depositary on the date of issuance of that Receipt.

-5-

The Receipts may be endorsed with or have incorporated in the text thereof such legends or recitals or modifications not inconsistent with the provisions of this Deposit Agreement as may be reasonably required by the Depositary or required to comply with any applicable law or regulations thereunder or with the rules and regulations of any securities exchange upon which American Depositary Shares may be listed or to conform with any usage with respect thereto, or to indicate any special limitations or restrictions to which any particular Receipts are subject by reason of the date of issuance of the underlying Deposited Securities or otherwise.

American Depositary Shares evidenced by a Receipt, when properly endorsed or accompanied by proper instruments of transfer, shall be transferable as certificated registered securities under the laws of the State of New York. American Depositary Shares not evidenced by Receipts shall be transferable as uncertificated registered securities under the laws of the State of New York. The Depositary, notwithstanding any notice to the contrary, may treat the Owner of American Depositary Shares as the absolute owner thereof for the purpose of determining the person entitled to distribution of dividends or other distributions or to any notice provided for in this Deposit Agreement and for all other purposes, and neither the Depositary nor the Company shall have any obligation or be subject to any liability under this Deposit Agreement to any Holder of American Depositary Shares unless that Holder is the Owner of those American Depositary Shares.

SECTION 2.2 Deposit of Shares.

Subject to the terms and conditions of this Deposit Agreement, Shares or evidence of rights to receive Shares may be deposited by delivery thereof to any Custodian hereunder, accompanied by any appropriate instruments or instructions for transfer, or endorsement, in form satisfactory to the Custodian, together with all such certifications as may be required by the Depositary or the Custodian in accordance with the provisions of this Deposit Agreement, and, if the Depositary requires, together with a written order directing the Depositary to deliver to, or upon the written order of, the person or persons stated in such order, the number of American Depositary Shares representing such deposit.

No Share shall be accepted for deposit unless accompanied by evidence reasonably satisfactory to the Depositary that any necessary approval has been granted by any governmental body in Belgium that is then performing the function of the regulation of currency exchange. If required by the Depositary, Shares presented for deposit at any time, whether or not the transfer books of the Company or the Foreign Registrar, if applicable, are closed, shall also be accompanied by an agreement or assignment, or other instrument satisfactory to the Depositary, which will provide for the prompt transfer to the Custodian of any dividend, or right to subscribe for additional Shares or to receive other property which any person in whose name the Shares are or have been recorded may thereafter receive upon or in respect of such deposited Shares, or in lieu thereof, such agreement of indemnity or other agreement as shall be satisfactory to the Depositary.

-6-

Deposited Securities shall be held by the Depositary or by a Custodian for the account and to the order of the Depositary or at such other place or places as the Depositary shall determine.

SECTION 2.3 Delivery of American Depositary Shares.

Upon receipt by any Custodian of any deposit pursuant to Section 2.2 hereunder, together with the other documents required as specified above, such Custodian shall notify the Depositary of such deposit and the person or persons to whom or upon whose written order American Depositary Shares are deliverable in respect thereof and the number of American Depositary Shares to be so delivered. Such notification shall be made by letter or, at the request, risk and expense of the person making the deposit, by cable, telex or facsimile transmission (and in addition, if the transfer books of the Company or the Foreign Registrar, if applicable, are open, the Depositary may in its sole discretion require a proper acknowledgment or other evidence from the Company or the Foreign Registrar that any Deposited Securities have been recorded upon the books of the Company or the Foreign Registrar, if applicable, in the name of the Depositary or its nominee or such Custodian or its nominee). Upon receiving such notice from such Custodian, or upon the receipt of Shares or evidence of the right to receive Shares by the Depositary, the Depositary, subject to the terms and conditions of this Deposit Agreement, shall deliver, to or upon the order of the person or persons entitled thereto, the number of American Depositary Shares issuable in respect of that deposit, but only upon payment to the Depositary of the fees and expenses of the Depositary for the delivery of such American Depositary Shares as provided in Section 5.9, and of all taxes and governmental charges and fees payable in connection with such deposit and the transfer of the Deposited Securities.

SECTION 2.4 Registration of Transfer of American Depositary Shares; Combination and Split-up of Receipts; Interchange of Certificated and Uncertificated American Depositary Shares.

The Depositary, subject to the terms and conditions of this Deposit Agreement, shall register transfers of American Depositary Shares on its transfer books from time to time, upon (i) in the case of certificated American Depositary Shares, surrender of the Receipt evidencing those American Depositary Shares, by the Owner in person or by a duly authorized attorney, properly endorsed or accompanied by proper instruments of transfer or (ii) in the case of uncertificated American Depositary Shares, receipt from the Owner of a proper instruction (including, for the avoidance of doubt, instructions through DRS and Profile as provided in Section 2.10), and, in either case, duly stamped as may be required by the laws of the State of New York and of the United States of America. Thereupon the Depositary shall deliver those American Depositary Shares to or upon the order of the person entitled thereto.

-7-

The Depositary, subject to the terms and conditions of this Deposit Agreement, shall upon surrender of a Receipt or Receipts for the purpose of effecting a split-up or combination of such Receipt or Receipts, execute and deliver a new Receipt or Receipts for any authorized number of American Depositary Shares requested, evidencing the same aggregate number of American Depositary Shares as the Receipt or Receipts surrendered.

The Depositary, upon surrender of certificated American Depositary Shares for the purpose of exchanging for uncertificated American Depositary Shares, shall cancel those certificated American Depositary Shares and send the Owner a statement confirming that the Owner is the owner of the same number of uncertificated American Depositary Shares. The Depositary, upon receipt of a proper instruction (including, for the avoidance of doubt, instructions through DRS and Profile as provided in Section 2.10) from the Owner of uncertificated American Depositary Shares for the purpose of exchanging for certificated American Depositary Shares, shall cancel those uncertificated American Depositary Shares and deliver to the Owner the same number of certificated American Depositary Shares.

The Depositary may appoint one or more co-transfer agents for the purpose of effecting registration of transfers of American Depositary Shares and combinations and split-ups of Receipts at designated transfer offices on behalf of the Depositary. In carrying out its functions, a co-transfer agent may require evidence of authority and compliance with applicable laws and other requirements by Owners or persons entitled to American Depositary Shares and will be entitled to protection and indemnity to the same extent as the Depositary.

SECTION 2.5 Surrender of American Depositary Shares and Withdrawal of Deposited Securities.

Upon surrender and cancellation at the Corporate Trust Office of the Depositary of American Depositary Shares for the purpose of withdrawal of the Deposited Securities represented thereby, and upon payment of the fee of the Depositary for the surrender of American Depositary Shares as provided in Section 5.9 and payment of all taxes and governmental charges payable in connection with such surrender and withdrawal of the Deposited Securities, and subject to the terms and conditions of this Deposit Agreement, the Owner of those American Depositary Shares shall be entitled to delivery, to him or as instructed, of the amount of Deposited Securities at the time represented by those American Depositary Shares. Such delivery shall be made, as hereinafter provided, without unreasonable delay.

A Receipt surrendered for such purposes may be required by the Depositary to be properly endorsed in blank or accompanied by proper instruments of

-8-

transfer in blank. The Depositary may require the surrendering Owner to execute and deliver 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 a person or persons designated in such order. Thereupon the Depositary shall direct the Custodian to deliver at the office of such Custodian, subject to Sections 2.6, 3.1 and 3.2 and to the other terms and conditions of this Deposit Agreement, to or upon the written order of the person or persons designated in the order delivered to the Depositary as above provided, the amount of Deposited Securities represented by the surrendered American Depositary Shares, except that the Depositary may make delivery to such person or persons at the Corporate Trust Office of the Depositary of any dividends or distributions with respect to the Deposited Securities represented by those American Depositary Shares, or of any proceeds of sale of any dividends, distributions or rights, which may at the time be held by the Depositary.

At the request, risk and expense of any Owner so surrendering American Depositary Shares, and for the account of such Owner, the Depositary shall direct the Custodian to forward any cash or other property (other than rights) comprising, and forward a certificate or certificates, if applicable, and other proper documents of title for, the Deposited Securities represented by the surrendered American Depositary Shares to the Depositary for delivery at the Corporate Trust Office of the Depositary. Such direction shall be given by letter or, at the request, risk and expense of such Owner, by cable, telex or facsimile transmission.

SECTION 2.6 Limitations on Delivery, Transfer and Surrender of American Depositary Shares.

As a condition precedent to the delivery, registration of transfer or surrender of any American Depositary Shares or split-up or combination of any Receipt or withdrawal of any Deposited Securities, the Depositary, Custodian or Registrar may require payment from the depositor of Shares or the presenter of the Receipt or instruction for registration of transfer or surrender of American Depositary Shares not evidenced by a Receipt 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 as herein provided, may require the production of proof satisfactory to it as to the identity and genuineness of any signature and may also require compliance with any regulations the Depositary may establish consistent with the provisions of this Deposit Agreement, including, without limitation, this Section 2.6.

-9-

any period when the transfer books of the Depositary are closed, or if any such action is deemed necessary or advisable by the Depositary or the Company at any time or from time to time because of any requirement of law or of any government or governmental body or commission, or under any provision of this Deposit Agreement, or for any other reason, subject to the provisions of the following sentence. Notwithstanding anything to the contrary in this Deposit Agreement, the surrender of outstanding American Depositary Shares and withdrawal of Deposited Securities may not be suspended subject only to (i) temporary delays caused by closing the transfer books of the Depositary or the Company or the Foreign Registrar, if 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, and (iii) compliance with any U.S. or foreign laws or governmental regulations relating to the American Depositary Shares or to the withdrawal of the Deposited Securities. Without limitation of the foregoing, the Depositary shall not knowingly accept for deposit under this Deposit Agreement any Shares which would be required to be registered under the provisions of the Securities Act of 1933 for public offer and sale in the United States unless a registration statement is in effect as to such Shares for such offer and sale.

SECTION 2.7 Lost Receipts, etc.

In case any Receipt shall be mutilated, destroyed, lost or stolen, the Depositary shall deliver to the Owner the American Depositary Shares evidenced by that Receipt in uncertificated form or, if requested by the Owner, execute and deliver a new Receipt of like tenor in exchange and substitution for such mutilated Receipt, upon cancellation thereof, or in lieu of and in substitution for such destroyed, lost or stolen Receipt. Before the Depositary shall deliver American Depositary Shares in uncertificated form or execute and deliver a new Receipt, in substitution for a destroyed, lost or stolen Receipt, the Owner thereof shall have (a) filed with the Depositary (i) a request for such execution and delivery before the Depositary has notice that the Receipt has been acquired by a bona fide purchaser and (ii) a sufficient indemnity bond and (b) satisfied any other reasonable requirements imposed by the Depositary.

SECTION 2.8 Cancellation and Destruction of Surrendered Receipts.

All Receipts surrendered to the Depositary shall be cancelled by the Depositary. The Depositary is authorized to destroy Receipts so cancelled.

SECTION 2.9 Pre-Release of American Depositary Shares.

Unless requested in writing by the Company to cease doing so, and notwithstanding Section 2.3 hereof, the Depositary may deliver American Depositary Shares prior to the receipt of Shares pursuant to Section 2.2 (a “Pre-Release”). The Depositary may, pursuant to Section 2.5, deliver Shares upon the surrender and cancellation of American Depositary Shares that have been Pre-Released, whether or not such cancellation is prior to the termination of such Pre-Release or the Depositary knows

-10-

that such American Depositary Shares have been Pre-Released. The Depositary may accept American Depositary Shares in lieu of Shares in satisfaction of a Pre-Release. Each Pre-Release will be (a) preceded or accompanied by a written representation and agreement from the person to whom American Depositary Shares are to be delivered, that such person, or its customer, (i) owns or represents the owner of the corresponding Shares to be remitted, (ii) assigns all beneficial right, title and interest in such Shares to the Depositary in its capacity as such and for the benefit of the Holders, and (iii) will not take any action with respect to such Shares that is inconsistent with the transfer of beneficial ownership (including without the consent of the Depositary, disposing of such Shares), other than in satisfaction of such Pre-Release, (b) at all times fully collateralized with cash 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 number of Shares represented by American Depositary Shares which are outstanding at any time as a result of Pre-Release will not normally exceed thirty percent (30%) of the Shares deposited hereunder; provided, however, that the Depositary reserves the right to change or disregard such limit from time to time as it deems appropriate, and may, with the prior written consent of the Company, change such limit for the purposes of general application.

The Depositary may retain for its own account any compensation received by it in connection with the foregoing.

SECTION 2.10 DTC Direct Registration System and Profile Modification System.

(a) Notwithstanding the provisions of Section 2.4, the parties acknowledge that the Direct Registration System (“DRS”) and Profile Modification System (“Profile”) shall apply to uncertificated American Depositary Shares upon acceptance thereof to DRS by DTC. DRS is the system administered by DTC pursuant to which the Depositary may register the ownership of uncertificated American Depositary Shares, which ownership shall be evidenced by periodic statements issued by the Depositary to the Owners entitled thereto. Profile is a required feature of DRS which allows a DTC participant, claiming to act on behalf of an Owner of American Depositary Shares, to direct the Depositary to register a transfer of those American Depositary Shares to DTC or its nominee and to deliver those American Depositary Shares to the DTC account of that DTC participant without receipt by the Depositary of prior authorization from the Owner to register such transfer.

-11-

(notwithstanding any requirements under the Uniform Commercial Code). For the avoidance of doubt, the provisions of Sections 5.3 and 5.8 shall apply to the matters arising from the use of the DRS. The parties agree that the Depositary’s reliance on and compliance with instructions received by the Depositary through the DRS/Profile System and in accordance with this Deposit Agreement shall not constitute negligence or bad faith on the part of the Depositary.

ARTICLE 3. CERTAIN OBLIGATIONS OF OWNERS AND HOLDERS OF AMERICAN DEPOSITARY SHARES

SECTION 3.1 Filing Proofs, Certificates and Other Information.

Any person presenting Shares for deposit or any Owner or Holder may be required from time to time to file with the Depositary or the Custodian such proof of citizenship or residence, exchange control approval, or such information relating to the registration on the books of the Company or the Foreign Registrar, if applicable, to execute such certificates and to make such representations and warranties, as the Depositary may deem necessary or proper. The Depositary may withhold the delivery or registration of transfer of American Depositary Shares or the distribution of any dividend or sale or distribution of rights or of the proceeds thereof or the delivery of any Deposited Securities until such proof or other information is filed or such certificates are executed or such representations and warranties made.

SECTION 3.2 Liability of Owner for Taxes.

If any tax or other governmental charge shall become payable by the Custodian or the Depositary with respect to any American Depositary Shares or any Deposited Securities represented by any American Depositary Shares, such tax or other governmental charge shall be payable by the Owner of such American Depositary Shares to the Depositary. The Depositary may refuse to register any transfer of those American Depositary Shares or any withdrawal of Deposited Securities represented by those American Depositary Shares until such payment is made, and may withhold any dividends or other distributions, or may sell for the account of the Owner thereof any part or all of the Deposited Securities represented by those American Depositary Shares, and may apply such dividends or other distributions or the proceeds of any such sale in payment of such tax or other governmental charge and the Owner of such American Depositary Shares shall remain liable for any deficiency.

SECTION 3.3 Warranties on Deposit of Shares.

Every person depositing Shares under this Deposit Agreement shall be deemed thereby to represent and warrant that such Shares and each certificate therefor, if applicable, are validly issued, fully paid, nonassessable and free of any preemptive rights of the holders of outstanding Shares and that the person making such deposit is duly authorized so to do. Every such person shall also be deemed to represent that the deposit of such Shares and the sale of American Depositary Shares representing such Shares by that person are not restricted under the Securities Act of 1933. Such representations and warranties shall survive the deposit of Shares and delivery of American Depositary Shares.

-12-

SECTION 3.4 Disclosure of Interests.

Notwithstanding any other provision of this Deposit Agreement, each Owner and Holder agrees to comply with requests from the Company pursuant to applicable law, the rules and requirements of any stock exchange on which the American Depositary Shares are, or will be, registered, traded or listed, the rules and requirements of any clearing system through which transactions in the American Depositary Shares may be settled or the articles of association of the Company, as in effect from time to time, to provide information, inter alia, as to the capacity in which such Owner or Holder owns American Depositary Shares (and Shares as the case may be) and regarding the identity of any other person(s) interested in such American Depositary Shares (and Shares, as the case may be) and the nature of such interest and various other matters, whether or not they are Owners or Holders at the time of such request. The Depositary shall provide reasonable assistance to the Company, at the Company’s request and expense, in obtaining information sought by the Company pursuant to this Section 3.4.

ARTICLE 4. THE DEPOSITED SECURITIES

SECTION 4.1 Cash Distributions.

Whenever the Depositary shall receive any cash dividend or other cash distribution on any Deposited Securities, the Depositary shall, subject to the provisions of Section 4.5, convert such dividend or distribution into Dollars and shall distribute the amount thus received (net of the fees and expenses of the Depositary as provided in Section 5.9) to the Owners entitled thereto, in proportion to the number of American Depositary Shares representing such Deposited Securities held by them respectively; provided, however, that in the event that the Custodian or the Depositary shall be required to withhold and does withhold from such cash dividend or such other cash distribution an amount on account of taxes or other governmental charges, the amount distributed to the Owner of the American Depositary Shares representing such Deposited Securities shall be reduced accordingly. The Depositary shall distribute only such amount, however, as can be distributed without attributing to any Owner a fraction of one cent. Any such fractional amounts shall be rounded to the nearest whole cent and so distributed to Owners entitled thereto. The Company or its agent will remit to the appropriate governmental agency in Belgium all amounts withheld and owing to such agency. The Depositary will forward to the Company or its agent such information from its records as the Company may reasonably request to enable the Company or its agent to file necessary reports with governmental agencies.

SECTION 4.2 Distributions Other Than Cash, Shares or Rights.

-13-

Subject to the provisions of Sections 4.11 and 5.9, whenever the Depositary shall receive any distribution other than a distribution described in Section 4.1, 4.3 or 4.4, the Depositary shall cause the securities or property received by it to be distributed to the Owners entitled thereto, after deduction or upon payment of any fees and expenses of the Depositary or any taxes or other governmental charges, in proportion to the number of American Depositary Shares representing such Deposited Securities held by them respectively, in any manner that the Depositary may deem equitable and practicable for accomplishing such distribution; provided, however, that if in the opinion of the Depositary such distribution cannot be made proportionately among the Owners entitled thereto, or if for any other reason (including, but not limited to, any requirement that the Company or the Depositary withhold an amount on account of taxes or other governmental charges or that such securities must be registered under the Securities Act of 1933 in order to be distributed to Owners or Holders) the Depositary deems such distribution not to be feasible, the Depositary may adopt such method as it may deem equitable and practicable for the purpose of effecting such distribution, including, but not limited to, the public or private sale of the securities or property thus received, or any part thereof, and the net proceeds of any such sale (net of the fees and expenses of the Depositary as provided in Section 5.9) shall be distributed by the Depositary to the Owners entitled thereto, all in the manner and subject to the conditions described in Section 4.1. The Depositary may withhold any distribution of securities under this Section 4.2 if it has not received reasonably satisfactory assurances from the Company that the distribution does not require registration under the Securities Act of 1933. The Depositary may sell, by public or private sale, an amount of securities or other property it would otherwise distribute under this Section 4.2 that is sufficient to pay its fees and expenses in respect of that distribution.

SECTION 4.3 Distributions in Shares.

If any distribution upon any Deposited Securities consists of a dividend in, or free distribution of, Shares, the Depositary may, and upon the Company’s written request, shall deliver to the Owners entitled thereto, in proportion to the number of American Depositary Shares representing such Deposited Securities held by them respectively, an aggregate number of American Depositary Shares representing the amount of Shares received as such dividend or free distribution, subject to the terms and conditions of the Deposit Agreement with respect to the deposit of Shares and after deduction or upon issuance of American Depositary Shares, including the withholding of any tax or other governmental charge as provided in Section 4.11 and the payment of the fees and expenses of the Depositary as provided in Section 5.9 (and the Depositary may sell, by public or private sale, an amount of the Shares received sufficient to pay its fees and expenses in respect of that distribution). The Depositary may withhold any such delivery of American Depositary Shares if it has not received satisfactory assurances from the Company that such distribution does not require registration under the Securities Act of 1933. In lieu of delivering fractional American Depositary Shares in any such case, the Depositary shall use reasonable efforts to sell the amount of Shares represented

by the aggregate of such fractions (or American Depositary Shares representing those Shares) and distribute the net proceeds, all in the manner and subject to the conditions described in Section 4.1. If additional American Depositary Shares are not so delivered, the Depositary agrees to consult with the Company in good faith concerning the appropriate treatment of such additional Shares.

SECTION 4.4 Rights.

In the event that the Company shall offer or cause to be offered to the holders of any Deposited Securities any rights to subscribe for additional Shares or any rights of any other nature, the Depositary shall have discretion as to the procedure to be followed in making such rights available to any Owners or in disposing of such rights on behalf of any Owners and making the net proceeds available to such Owners or, if by the terms of such rights offering or for any other reason, the Depositary may not either make such rights available to any Owners or dispose of such rights and make the net proceeds available to such Owners, then the Depositary shall allow the rights to lapse. If at the time of the offering of any rights the Depositary determines in its discretion that it is lawful and feasible to make such rights available to all or certain Owners but not to other Owners, the Depositary may distribute to any Owner to whom it determines the distribution to be lawful and feasible, in proportion to the number of American Depositary Shares held by such Owner, warrants or other instruments therefor in such form as it deems appropriate.

In circumstances in which rights would otherwise not be distributed, if an Owner requests the distribution of warrants or other instruments in order to exercise the rights allocable to the American Depositary Shares of such Owner hereunder, the Depositary will make such rights available to such Owner upon written notice from the Company to the Depositary that (a) the Company has elected in its sole discretion to permit such rights to be exercised and (b) such Owner has executed such documents as the Company has determined in its sole discretion are reasonably required under applicable law.

If the Depositary has distributed warrants or other instruments for rights to all or certain Owners, then upon instruction from such an Owner pursuant to such warrants or other instruments to the Depositary from such Owner to exercise such rights, upon payment by such Owner to the Depositary for the account of such Owner of an amount equal to the purchase price of the Shares to be received upon the exercise of the rights, and upon payment of the fees and expenses of the Depositary and any other charges as set forth in such warrants or other instruments, the Depositary shall, on behalf of such Owner, exercise the rights and purchase the Shares, and the Company shall cause the Shares so purchased to be delivered to the Depositary on behalf of such Owner. As agent for such Owner, the Depositary will cause the Shares so purchased to be deposited pursuant to Section 2.2 of this Deposit Agreement, and shall, pursuant to Section 2.3 of this Deposit Agreement, deliver American Depositary Shares to such Owner. In the case

-15-

of a distribution pursuant to the second paragraph of this Section, such deposit shall be made, and depositary shares shall be delivered, under depositary arrangements which provide for issuance of depositary shares subject to the appropriate restrictions on sale, deposit, cancellation, and transfer under applicable United States laws.

If the Depositary determines in its discretion that it is not lawful and feasible to make such rights available to all or certain Owners, it may sell the rights, warrants or other instruments in proportion to the number of American Depositary Shares held by the Owners to whom it has determined it may not lawfully or feasibly make such rights available, and allocate the net proceeds of such sales (net of the fees and expenses of the Depositary as provided in Section 5.9 and all taxes and governmental charges payable in connection with such rights and subject to the terms and conditions of this Deposit Agreement) for the account of such Owners otherwise entitled to such rights, warrants or other instruments, upon an averaged or other practical basis without regard to any distinctions among such Owners because of exchange restrictions or the date of delivery of any American Depositary Shares or otherwise.

The Depositary will not offer rights to Owners unless both the rights and the securities to which such rights relate are either exempt from registration under the Securities Act of 1933 with respect to a distribution to all Owners or are registered under the provisions of such Act; provided, that nothing in this Deposit Agreement shall create any obligation on the part of the Company to file a registration statement with respect to such rights or underlying securities or to endeavor to have such a registration statement declared effective. If an Owner requests the distribution of warrants or other instruments, notwithstanding that there has been no such registration under the Securities Act of 1933, the Depositary shall not effect such distribution unless it has received an opinion from recognized counsel in the United States for the Company upon which the Depositary may rely that such distribution to such Owner is exempt from such registration.

Neither the Depositary nor the Company shall be responsible for any failure to determine that it may be lawful or feasible to make such rights available to Owners in general or any Owner in particular.

SECTION 4.5 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 securities, property or rights, and if at the time of the receipt thereof the foreign currency so received can in the judgment of the Depositary be converted on a reasonable basis into Dollars and the resulting Dollars transferred to the United States, the Depositary shall as promptly as practicable convert or cause to be converted by sale or in any other manner that it may determine such foreign currency into Dollars, and such Dollars shall be distributed to the Owners entitled thereto or, if the Depositary shall have distributed any warrants or other instruments which entitle the holders thereof to such Dollars, then to the holders of such warrants and/or instruments upon surrender thereof for cancellation.

-16-

Such distribution may be made upon an averaged or other practicable basis without regard to any distinctions among Owners on account of exchange restrictions, the date of delivery of any American Depositary Shares or otherwise and shall be net of any expenses of conversion into Dollars incurred by the Depositary as provided in Section 5.9.

If such conversion or distribution can be effected only with the approval or license of any government or agency thereof, the Depositary shall file such application for approval or license, if any, as it may deem desirable.

If at any time the Depositary shall determine that in its judgment any foreign currency received by the Depositary or the Custodian is not convertible on a reasonable basis into Dollars transferable to the United States, or if any approval or license of any government or agency thereof which is required for such conversion is denied or in the opinion of the Depositary is not obtainable, or if any such approval or license is not obtained within a reasonable period as determined by the Depositary, the Depositary may distribute the foreign currency (or an appropriate document evidencing the right to receive such foreign currency) received by the Depositary to, or in its discretion may hold such foreign currency uninvested and without liability for interest thereon for the respective accounts of, the Owners entitled to receive the same.

If any such conversion of foreign currency, in whole or in part, cannot be effected for distribution to some of the Owners entitled thereto, the Depositary may in its discretion make such conversion and distribution in Dollars to the extent permissible to the Owners entitled thereto and may distribute the balance of the foreign currency received by the Depositary to, or hold such balance uninvested and without liability for interest thereon for the respective accounts of, the Owners entitled thereto.

SECTION 4.6 Fixing of Record Date.

Whenever any cash dividend or other cash distribution shall become payable or any distribution other than cash shall be made, or whenever rights shall be issued with respect to the Deposited Securities, or whenever the Depositary shall receive notice of any meeting of holders of Shares or other Deposited Securities, or whenever for any reason the Depositary causes a change in the number of Shares that are represented by each American Depositary Share, or whenever the Depositary shall find it necessary or convenient, the Depositary shall, after consultation with the Company to the extent practicable, fix a record date (a) for the determination of the Owners who shall be (i) entitled to receive such dividend, distribution or rights or the net proceeds of the sale thereof, (ii) entitled to give instructions for the exercise of voting rights at any such meeting or (iii) responsible for any fee or charge assessed by the Depositary pursuant to this Deposit Agreement, or (b) on or after which each American Depositary Share will represent the changed number of Shares. Subject to the provisions of Sections 4.1 through 4.5 and to the other terms and conditions of this Deposit Agreement, the Owners on such record date shall be entitled, as the case may be, to receive the amount distributable by the Depositary with respect to such dividend or other distribution or such rights or the net proceeds of sale thereof in proportion to the number of American Depositary Shares held by them respectively and to give voting instructions and to act in respect of any other such matter.

SECTION 4.7 Voting of Deposited Securities.

Upon receipt of notice of any meeting or solicitation or proxies or consents of holders of Shares or other Deposited Securities, if requested in writing by the Company, the Depositary shall, as soon as practicable thereafter, mail to the Owners a notice, the form of which notice , which shall be previously provided to the Company, shall be at the discretion of the Depositary (unless otherwise advised to the Depositary by the Company in writing), which shall contain (a) such information as is contained in such notice of meeting received by the Depositary from the Company, (b) a statement that the Owners as of the close of business on a specified record date will be entitled, subject to any applicable provision of Belgian law and of the articles of association or similar document of the Company and any other provisions governing Deposited Securities, to instruct the Depositary as to the exercise of the voting rights, if any, pertaining to the amount of Shares or other Deposited Securities represented by their respective American Depositary Shares and (c) a statement as to the manner in which such instructions may be given including an express indication that instructions may be given (or be deemed given in accordance with the last sentence of this paragraph if no instruction is received) to the Depositary to give a discretionary proxy to a person designated by the Company. Upon the written request of an Owner on such record date, received on or before the date established by the Depositary for such purpose, the Depositary shall endeavor, insofar as practicable, to vote or cause to be voted the amount of Shares or other Deposited Securities represented by the American Depositary Shares in accordance with the instructions set forth in such request. The Depositary shall not vote or attempt to exercise the right to vote that attaches to the Shares or other Deposited Securities, other than in accordance with such instructions or deemed instructions. If (i) the Company has requested the Depositary to send a notice under this paragraph and has provided the Depositary not less than 30 days’ notice of the meeting and details of the matters to be voted upon and (ii) no instructions are received by the Depositary from an Owner with respect to Deposited Securities represented by American Depositary Shares of that Owner on or before the date established by the Depositary for such purpose, the Depositary shall deem such Owner to have instructed the Depositary to give a discretionary proxy to a person designated by the Company with respect to such Deposited Securities and the Depositary shall, only if instructed by the Company in writing to do so, give a discretionary proxy to a person designated by the Company to vote such Deposited Securities, provided, that no such instruction shall be deemed given and no such discretionary proxy shall be given with respect to any matter as to which the Company informs the Depositary (and the Company agrees to provide such information as promptly as practicable in writing, if applicable) that (x) substantial opposition exists or (y) such matter materially and adversely affects the rights of holders of Shares.

-18-

There can be no assurance that Owners generally or any Owner in particular will receive the notice described in the preceding paragraph sufficiently prior to the instruction cut-off date to ensure that the Depositary will vote the Shares or Deposited Securities in accordance with the provisions set forth in the preceding paragraph.

In any such case the Depositary may deliver additional American Depositary Shares as in the case of a dividend in Shares, or call for the surrender of outstanding Receipts to be exchanged for new Receipts specifically describing such new Deposited Securities.

SECTION 4.9 Reports.

The Depositary shall make available for inspection by Owners at its Corporate Trust Office any reports and communications, including any proxy solicitation material, received from the Company which are both (a) received by the Depositary as the holder of the Deposited Securities and (b) made generally available to the holders of such Deposited Securities by the Company.

SECTION 4.11 Withholding.

In the event that the Depositary reasonably determines that any distribution in property (including Shares and rights to subscribe therefor) is subject to any tax or other governmental charge which the Depositary is obligated to withhold, the Depositary may by public or private sale dispose of all or a portion of such property (including Shares and rights to subscribe therefor) in such amounts and in such manner as the Depositary reasonably deems necessary and practicable to pay such taxes or charges and the Depositary shall distribute the net proceeds of any such sale after deduction of such taxes or charges to the Owners entitled thereto in proportion to the number of American Depositary Shares held by them respectively.

-24-

writing by the Depositary, the Company shall promptly furnish to the Depositary a written opinion from U.S. counsel for the Company that is reasonably satisfactory to the Depositary, stating whether or not the Distribution requires, or, if made in the United States, would require, registration under the Securities Act of 1933. If, in the opinion of that counsel, the Distribution requires, or, if made in the United States, would require, registration under the Securities Act of 1933, that counsel shall furnish to the Depositary a written opinion as to whether or not there is a registration statement under the Securities Act of 1933 in effect that will cover that Distribution.

SECTION 5.8 Indemnification.

The Company agrees to indemnify the Depositary, its directors, employees, agents and affiliates and any Custodian against, and hold each of them harmless from, any liability or expense (including, but not limited to any fees and expenses incurred in seeking, enforcing or collecting such indemnity and the reasonable fees and expenses of counsel) which may arise out of or in connection with (a) any registration with the Commission of American Depositary Shares or Deposited Securities or the offer or sale thereof in the United States or (b) acts performed or omitted, pursuant to the provisions of or in connection with this Deposit Agreement and of the American Depositary Shares, as the same may be amended, modified or supplemented from time to time, (i) by either the Depositary or a Custodian or their respective directors, employees, agents and affiliates, except for any liability or expense arising out of the negligence or bad faith of either of them, or (ii) by the Company or any of its directors, employees, agents and affiliates.

The indemnities contained in the preceding paragraph shall not extend to any liability or expense to the extent such liability or expense arises solely and exclusively out of a Pre-Release (as defined in Section 2.9) of American Depositary Shares in accordance with Section 2.9 and which would not otherwise have arisen had those American Depositary Shares not been the subject of a Pre-Release pursuant to Section 2.9; provided, however, that the indemnities provided in the preceding paragraph shall apply to any such liability or expense (i) to the extent that such liability or expense would have arisen had those American Depositary Shares not be the subject of a Pre-Release, or (ii) which may arise out of any misstatement or alleged misstatement or omission or alleged omission in any registration statement, proxy statement, prospectus

-25-

(or placement memorandum), or preliminary prospectus (or preliminary placement memorandum) relating to the offer or sale of American Depositary Shares, except to the extent any such liability or expense arises out of (x) information relating to the Depositary or any Custodian (other than the Company), as applicable, furnished in writing and not materially changed or altered by the Company expressly for use in any of the foregoing documents, or, (y) if such information is provided, the failure to state a material fact necessary to make the information provided not misleading.

The Depositary agrees to indemnify the Company, its directors, officers, employees, agents and affiliates and hold them harmless from any liability or expense (including, but not limited to any fees and expenses incurred in seeking, enforcing or collecting such indemnity and the reasonable fees and expenses of counsel) which may arise out of acts performed or omitted by the Depositary or its Custodian or their respective directors, employees, agents and affiliates due to their negligence or bad faith.

If an action, proceeding (including, but not limited to, any governmental investigation), claim or dispute (collectively, a “Proceeding”) in respect of which indemnity may be sought by either party is brought or asserted against the other party, the party seeking indemnification (the “Indemnitee”) shall promptly (and in no event more than ten (10) days after receipt of notice of such Proceeding) notify the party obligated to provide such indemnification (the “Indemnitor”) of such Proceeding. The failure of the Indemnitee to so notify the Indemnitor shall not impair the Indemnitee’s ability to seek indemnification from the Indemnitor (but only for costs, expenses and liabilities incurred after such notice) unless such failure adversely affects the Indemnitor’s ability to adequately oppose or defend such Proceeding. Upon receipt of such notice from the Indemnitee, the Indemnitor shall be entitled to participate in such Proceeding and, to the extent that it shall so desire and provided no conflict of interest exists as specified in subparagraph (b) below and there are no other defenses available to Indemnitee as specified in subparagraph (d) below, to assume the defense thereof with counsel reasonably satisfactory to the Indemnitee (in which case all attorney’s fees and expenses shall be borne by the Indemnitor and the Indemnitor shall in good faith defend the Indemnitee). The Indemnitee shall have the right to employ separate counsel in any such Proceeding and to participate in the defense thereof, but the fees and expenses of such counsel shall be borne by the Indemnitee unless (a) the Indemnitor agrees in writing to pay such fees and expenses, (b) the Indemnitee shall have reasonably and in good faith concluded that there is a conflict of interest between the Indemnitor and the Indemnitee in the conduct of the defense of such action, (c) the Indemnitor fails, within ten (10) days prior to the date the first response or appearance is required to be made in such Proceeding, to assume the defense of such Proceeding with counsel reasonably satisfactory to the Indemnitee or (d) there are legal defenses available to Indemnitee that are different from or are in addition to those available to the Indemnitor. No compromise or settlement of such Proceeding may be effected by either party without the other party’s consent unless (i) there is no finding or admission of any violation of law and no effect on any other claims that may be made against such other party and (ii) the sole relief

-26-

provided is monetary damages that are paid in full by the party seeking the settlement and for which the Indemnitee will not seek reimbursement of such amount from the Indemnitor. Neither party shall have any liability with respect to any compromise or settlement effected without its consent, which shall not be unreasonably withheld. The Indemnitor shall have no obligation to indemnify and hold harmless the Indemnitee from any loss, expense or liability incurred by the Indemnitee as a result of a default judgment entered against the Indemnitee unless such judgment was entered after the Indemnitor agreed, in writing, to assume the defense of such Proceeding.

1.	THE DEPOSIT AGREEMENT.

This American Depositary Receipt is one of an issue (herein called “Receipts”), all issued and to be issued upon the terms and conditions set forth in the deposit agreement, dated as of , 2014 (herein called the “Deposit Agreement”), by and among the Company, the Depositary, and all Owners and Holders from time to time of American Depositary Shares issued thereunder, each of whom by accepting American Depositary Shares agrees to become a party thereto and become bound by all the terms and conditions thereof. The Deposit Agreement sets forth the rights of Owners and Holders and the rights and duties of the Depositary in respect of the Shares deposited thereunder and any and all other securities, property and cash from time to time received in respect of such Shares and held thereunder (such Shares, securities, property, and cash are herein called “Deposited Securities”). Copies of the Deposit Agreement are on file at the Depositary’s Corporate Trust Office in New York City and at the office of the Custodian.

The statements made on the face and reverse of this Receipt are summaries of certain provisions of the Deposit Agreement and are qualified by and subject to the detailed provisions of the Deposit Agreement, to which reference is hereby made. Capitalized terms defined in the Deposit Agreement and not defined herein shall have the meanings set forth in the Deposit Agreement.

2.	SURRENDER OF RECEIPTS AND WITHDRAWAL OF SHARES.

Upon surrender at the Corporate Trust Office of the Depositary of American Depositary Shares, and upon payment of the fee of the Depositary provided in this Receipt, and subject to the terms and conditions of the Deposit Agreement, the Owner of those American Depositary Shares is entitled to delivery, to him or as instructed, of the amount of Deposited Securities at the time represented by those American Depositary Shares. Delivery of such Deposited Securities may be made by the delivery of (a) certificates or account transfer in the name of the Owner hereof or as ordered by him, with proper endorsement or accompanied by proper instruments or instructions of transfer and (b) any other securities, property and cash to which such Owner is then entitled in respect of this Receipt.

3.	TRANSFERS, SPLIT-UPS, AND COMBINATIONS OF RECEIPTS.

Transfers of American Depositary Shares may be registered on the books of the Depositary by the Owner in person or by a duly authorized attorney, upon surrender of those American Depositary Shares properly endorsed for transfer or accompanied by proper instruments of transfer, in the case of a Receipt, or pursuant to a proper instruction

(including, for the avoidance of doubt, instructions through DRS and Profile as provided in Section 2.10 of the Deposit Agreement), in the case of uncertificated American Depositary Shares, and funds sufficient to pay any applicable transfer taxes and the expenses of the Depositary and upon compliance with such regulations, if any, as the Depositary may establish for such purpose. This Receipt may be split into other such Receipts, or may be combined with other such Receipts into one Receipt, evidencing the same aggregate number of American Depositary Shares as the Receipt or Receipts surrendered. The Depositary, upon surrender of certificated American Depositary Shares for the purpose of exchanging for uncertificated American Depositary Shares, shall cancel those certificated American Depositary Shares and send the Owner a statement confirming that the Owner is the Owner of uncertificated American Depositary Shares. The Depositary, upon receipt of a proper instruction (including, for the avoidance of doubt, instructions through DRS and Profile as provided in Section 2.10 of the Deposit Agreement) from the Owner of uncertificated American Depositary Shares for the purpose of exchanging for certificated American Depositary Shares, shall cancel those uncertificated American Depositary Shares and deliver to the Owner the same number of certificated American Depositary Shares. As a condition precedent to the delivery, registration of transfer, or surrender of any American Depositary Shares or split-up or combination of any Receipt or withdrawal of any Deposited Securities, the Depositary, the Custodian, or Registrar may require payment from the depositor of the Shares or the presenter of the Receipt or instruction for registration of transfer or surrender of American Depositary Shares not evidenced by a Receipt 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 as provided in the Deposit Agreement, may require the production of proof satisfactory to it as to the identity and genuineness of any signature and may also require compliance with any regulations the Depositary may establish consistent with the provisions of the Deposit Agreement.

The delivery of American Depositary Shares against deposit of Shares generally or against deposit of particular Shares may be suspended, or the transfer of American Depositary Shares in particular instances may be refused, or the registration of transfer of outstanding American Depositary Shares generally may be suspended, during any period when the transfer books of the Depositary are closed, or if any such action is deemed necessary or advisable by the Depositary or the Company at any time or from time to time because of any requirement of law or of any government or governmental body or commission, or under any provision of the Deposit Agreement, or for any other reason, subject to the provisions of the following sentence. Notwithstanding anything to the contrary in the Deposit Agreement or this Receipt, the surrender of outstanding American Depositary Shares and withdrawal of Deposited Securities may not be suspended subject only to (i) temporary delays caused by closing the transfer books of the Depositary or the Company or the Foreign Registrar, if 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, and (iii) compliance with any U.S. or foreign laws or

A-2

governmental regulations relating to the American Depositary Shares or to the withdrawal of the Deposited Securities.

5.	WARRANTIES ON DEPOSIT OF SHARES.

Every person depositing Shares under the Deposit Agreement shall be deemed thereby to represent and warrant, that such Shares and each certificate therefor, if applicable, are validly issued, fully paid, nonassessable and free of any preemptive rights of the holders of outstanding Shares and that the person making such deposit is duly authorized so to do. Every such person shall also be deemed to represent that the deposit of such Shares and the sale of American Depositary Shares representing such Shares by that person are not restricted under the Securities Act of 1933. Such representations and warranties shall survive the deposit of Shares and delivery of American Depositary Shares.

6.	FILING PROOFS, CERTIFICATES, AND OTHER INFORMATION.

Any person presenting Shares for deposit or any Owner or Holder may be required from time to time to file with the Depositary or the Custodian such proof of citizenship or residence, exchange control approval, or such information relating to the registration on the books of the Company or the Foreign Registrar, if applicable, to execute such certificates and to make such representations and warranties, as the Depositary may deem necessary or proper. The Depositary may withhold the delivery or registration of transfer of any American Depositary Shares or the distribution of any dividend or sale or distribution of rights or of the proceeds thereof or the delivery of any Deposited Securities until such proof or other information is filed or such certificates are executed or such representations and warranties made.

Whenever the Depositary receives any cash dividend or other cash distribution on any Deposited Securities, the Depositary will, if at the time of receipt thereof any amounts received in a foreign currency can in the judgment of the Depositary be converted on a reasonable basis into United States dollars transferable to the United States, and subject to the Deposit Agreement, convert such dividend or distribution into dollars and will distribute the amount thus received (net of the fees and expenses of the Depositary as provided in Article 7 hereof and Section 5.9 of the Deposit Agreement) to the Owners entitled thereto; provided, however, that in the event that the Company or the Depositary is required to withhold and does withhold from any cash dividend or other cash distribution in respect of any Deposited Securities an amount on account of taxes or other governmental charges, the amount distributed to the Owners of the American Depositary Shares representing such Deposited Securities shall be reduced accordingly.

Subject to the provisions of Section 4.11 and 5.9 of the Deposit Agreement, whenever the Depositary receives any distribution other than a distribution described in Section 4.1, 4.3 or 4.4 of the Deposit Agreement, the Depositary will cause the securities or property received by it to be distributed to the Owners entitled thereto, in any manner that the Depositary may deem equitable and practicable for accomplishing such distribution; provided, however, that if in the opinion of the Depositary such distribution cannot be made proportionately among the Owners of Receipts entitled thereto, or if for any other reason the Depositary deems such distribution not to be feasible, the Depositary may adopt such method as it may deem equitable and practicable for the purpose of effecting such distribution, including, but not limited to, the public or private sale of the securities or property thus received, or any part thereof, and the net proceeds of any such sale (net of the fees and expenses of the Depositary as provided in Article 7 hereof and Section 5.9 of the Deposit Agreement) will be distributed by the Depositary to the Owners of Receipts entitled thereto all in the manner and subject to the conditions described in Section 4.1 of the Deposit Agreement. The Depositary may withhold any distribution of securities under Section 4.2 of the Deposit Agreement if it has not received reasonably satisfactory assurances from the Company that the distribution does not require registration under the Securities Act of 1933. The Depositary may sell, by public or private sale, an amount of securities or other property it would otherwise distribute under this Article that is sufficient to pay its fees and expenses in respect of that distribution.

A-7

If any distribution consists of a dividend in, or free distribution of, Shares, the Depositary may, and upon the Company’s written request, shall deliver to the Owners entitled thereto, an aggregate number of American Depositary Shares representing the amount of Shares received as such dividend or free distribution, subject to the terms and conditions of the Deposit Agreement with respect to the deposit of Shares and after deduction or upon issuance of American Depositary Shares, including the withholding of any tax or other governmental charge as provided in Section 4.11 of the Deposit Agreement and the payment of the fees and expenses of the Depositary as provided in Article 7 hereof and Section 5.9 of the Deposit Agreement (and the Depositary may sell, by public or private sale, an amount of Shares received sufficient to pay its fees and expenses in respect of that distribution. In lieu of delivering fractional American Depositary Shares in any such case, the Depositary shall use reasonable efforts to sell the amount of Shares represented by the aggregate of such fractions (or American Depositary Shares representing those Shares) and distribute the net proceeds, all in the manner and subject to the conditions described in Section 4.1 of the Deposit Agreement. If additional American Depositary Shares are not so delivered, the Depositary agrees to consult with the Company in good faith concerning the appropriate treatment of such additional Shares.

In the event that the Depositary reasonably determines that any distribution in property (including Shares and rights to subscribe therefor) is subject to any tax or other governmental charge which the Depositary is obligated to withhold, the Depositary may by public or private sale dispose of all or a portion of such property (including Shares and rights to subscribe therefor) in such amounts and in such manner as the Depositary reasonably deems necessary and practicable to pay any such taxes or charges, and the Depositary shall distribute the net proceeds of any such sale after deduction of such taxes or charges to the Owners of Receipts entitled thereto.

13.

RIGHTS.

A-8

In circumstances in which rights would otherwise not be distributed, if an Owner requests the distribution of warrants or other instruments in order to exercise the rights allocable to the American Depositary Shares of such Owner under the Deposit Agreement, the Depositary will make such rights available to such Owner upon written notice from the Company to the Depositary that (a) the Company has elected in its sole discretion to permit such rights to be exercised and (b) such Owner has executed such documents as the Company has determined in its sole discretion are reasonably required under applicable law.

If the Depositary has distributed warrants or other instruments for rights to all or certain Owners, then upon instruction from such an Owner pursuant to such warrants or other instruments to the Depositary from such Owner to exercise such rights, upon payment by such Owner to the Depositary for the account of such Owner of an amount equal to the purchase price of the Shares to be received upon the exercise of the rights, and upon payment of the fees and expenses of the Depositary and any other charges as set forth in such warrants or other instruments, the Depositary shall, on behalf of such Owner, exercise the rights and purchase the Shares, and the Company shall cause the Shares so purchased to be delivered to the Depositary on behalf of such Owner. As agent for such Owner, the Depositary will cause the Shares so purchased to be deposited pursuant to Section 2.2 of the Deposit Agreement, and shall, pursuant to Section 2.3 of the Deposit Agreement, deliver American Depositary Shares to such Owner. In the case of a distribution pursuant to the second paragraph of this Article 13, such deposit shall be made, and depositary shares shall be delivered, under depositary arrangements which provide for issuance of depositary shares subject to the appropriate restrictions on sale, deposit, cancellation, and transfer under applicable United States laws.

If the Depositary determines in its discretion that it is not lawful and feasible to make such rights available to all or certain Owners, it may sell the rights, warrants or other instruments in proportion to the number of American Depositary Shares held by the Owners to whom it has determined it may not lawfully or feasibly make such rights available, and allocate the net proceeds of such sales (net of the fees and expenses of the Depositary as provided in Section 5.9 of the Deposit Agreement and all taxes and governmental charges payable in connection with such rights and subject to the terms and conditions of the Deposit Agreement) for the account of such Owners otherwise entitled to such rights, warrants or other instruments, upon an averaged or other practical basis without regard to any distinctions among such Owners because of exchange restrictions or the date of delivery of any American Depositary Shares or otherwise.

The Depositary will not offer rights to Owners unless both the rights and the securities to which such rights relate are either exempt from registration under the

A-9

Securities Act of 1933 with respect to a distribution to all Owners or are registered under the provisions of such Act; provided, that nothing in the Deposit Agreement shall create any obligation on the part of the Company to file a registration statement with respect to such rights or underlying securities or to endeavor to have such a registration statement declared effective. If an Owner requests the distribution of warrants or other instruments, notwithstanding that there has been no such registration under the Securities Act of 1933, the Depositary shall not effect such distribution unless it has received an opinion from recognized counsel in the United States for the Company upon which the Depositary may rely that such distribution to such Owner is exempt from such registration.

14.	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 securities, property or rights, and if at the time of the receipt thereof the foreign currency so received can in the judgment of the Depositary be converted on a reasonable basis into Dollars and the resulting Dollars transferred to the United States, the Depositary shall, as promptly as practicable, convert or cause to be converted by sale or in any other manner that it may determine, such foreign currency into Dollars, and such Dollars shall be distributed to the Owners entitled thereto or, if the Depositary shall have distributed any warrants or other instruments which entitle the holders thereof to such Dollars, then to the holders of such warrants and/or instruments upon surrender thereof for cancellation. Such distribution may be made upon an averaged or other practicable basis without regard to any distinctions among Owners on account of exchange restrictions, the date of delivery of any American Depositary Shares or otherwise and shall be net of any expenses of conversion into Dollars incurred by the Depositary as provided in Section 5.9 of the Deposit Agreement.

A-10

15.	RECORD DATES.

Whenever any cash dividend or other cash distribution shall become payable or any distribution other than cash shall be made, or whenever rights shall be issued with respect to the Deposited Securities, or whenever the Depositary shall receive notice of any meeting of holders of Shares or other Deposited Securities, or whenever for any reason the Depositary causes a change in the number of Shares that are represented by each American Depositary Share, or whenever the Depositary shall find it necessary or convenient, the Depositary shall, after consultation with the Company to the extent practicable, fix a record date (a) for the determination of the Owners who shall be (i) entitled to receive such dividend, distribution or rights or the net proceeds of the sale thereof, (ii) entitled to give instructions for the exercise of voting rights at any such meeting or (iii) responsible for any fee assessed by the Depositary pursuant to the Deposit Agreement, or (b) on or after which each American Depositary Share will represent the changed number of Shares, subject to the provisions of the Deposit Agreement.

16.	VOTING OF DEPOSITED SECURITIES.

A-11

established by the Depositary for such purpose, the Depositary shall endeavor, insofar as practicable, to vote or cause to be voted the amount of Shares or other Deposited Securities represented by the American Depositary Shares in accordance with the instructions set forth in such request. The Depositary shall not vote or attempt to exercise the right to vote that attaches to the Shares or other Deposited Securities, other than in accordance with such instructions or deemed instructions. If (i) the Company has requested the Depositary to send a notice under this paragraph and has provided the Depositary not less than 30 days’ notice of the meeting and details of the matters to be voted upon and (ii) no instructions are received by the Depositary from an Owner with respect to Deposited Securities represented by American Depositary Shares of that Owner on or before the date established by the Depositary for such purpose, the Depositary shall deem such Owner to have instructed the Depositary to give a discretionary proxy to a person designated by the Company with respect to such Deposited Securities and the Depositary shall, only if instructed by the Company in writing to do so, give a discretionary proxy to a person designated by the Company to vote such Deposited Securities, provided, that no such instruction shall be deemed given and no such discretionary proxy shall be given with respect to any matter as to which the Company informs the Depositary (and the Company agrees to provide such information as promptly as practicable in writing, if applicable) that (x) substantial opposition exists or (y) such matter materially and adversely affects the rights of holders of Shares.

Notwithstanding anything else contained herein, the Depositary shall, if so requested in writing by the Company, represent all Deposited Securities (whether or not voting instructions have been received in respect of such Deposited Securities from Holders as of the abovementioned record date) for the sole purpose of establishing quorum at a meeting of shareholders.

17.	CHANGES AFFECTING DEPOSITED SECURITIES.

Upon any change in nominal value, change in par value, split-up, consolidation, or any other reclassification of Deposited Securities, or upon any recapitalization, reorganization, merger or consolidation, or sale of assets affecting the Company or to which it is a party, or upon the redemption or cancellation by the Company of the

A-12

Deposited Securities, any securities, cash or property which shall be received by the Depositary or a Custodian in exchange for, in conversion of, in lieu of or in respect of Deposited Securities shall be treated as new Deposited Securities under the Deposit Agreement, and American Depositary Shares shall thenceforth represent, in addition to the existing Deposited Securities, the right to receive the new Deposited Securities so received, unless additional Receipts are delivered pursuant to the following sentence. In any such case the Depositary may deliver additional American Depositary Shares as in the case of a dividend in Shares, or call for the surrender of outstanding Receipts to be exchanged for new Receipts specifically describing such new Deposited Securities.

18.	LIABILITY OF THE COMPANY AND DEPOSITARY.

Neither the Depositary nor the Company nor any of their respective directors, officers, employees, agents or affiliates shall incur any liability to any Owner or Holder, (i) if by reason of any provision of any present or future law or regulation of the United States or any other country, or of any governmental or regulatory authority, or by reason of any provision, present or future, of the articles of association or any similar document of the Company, or by reason of any provision of any securities issued or distributed by the Company, or any offering or distribution thereof, or by reason of any act of God or war or terrorism or other circumstances beyond its control, the Depositary or the Company shall be prevented, delayed or forbidden from or be subject to any civil or criminal penalty on account of doing or performing any act or thing which by the terms of the Deposit Agreement or Deposited Securities it is provided shall be done or performed, (ii) by reason of any non-performance or delay, caused as aforesaid, in the performance of any act or thing which by the terms of the Deposit Agreement it is provided shall or may be done or performed, (iii) by reason of any exercise of, or failure to exercise, any discretion provided for in the Deposit Agreement, (iv) for the inability of any Owner or Holder 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 Owners or Holders, or (v) for any special, consequential or punitive damages for any breach of the terms of the Deposit Agreement. Where, by the terms of a distribution pursuant to Section 4.1, 4.2 or 4.3 of the Deposit Agreement, or an offering or distribution pursuant to Section 4.4 of the Deposit Agreement, such distribution or offering may not be made available to Owners of Receipts, and the Depositary may not dispose of such distribution or offering on behalf of such Owners and make the net proceeds available to such Owners, then the Depositary shall not make such distribution or offering, and shall allow any rights, if applicable, to lapse. Neither the Company nor the Depositary nor any of their respective directors, officers, employees, agents or affiliates assumes any obligation or shall be subject to any liability under the Deposit Agreement to Owners or Holders, except that they agree to perform their obligations specifically set forth in the Deposit Agreement without negligence or bad faith. The Depositary shall not be subject to any liability with respect to the validity or worth of the Deposited Securities. Neither the Depositary nor the Company nor any of their respective directors, officers, employees, agents or affiliates

A-13

shall be under any obligation to appear in, prosecute or defend any action, suit, or other proceeding in respect of any Deposited Securities or in respect of the American Depositary Shares, on behalf of any Owner or Holder or other person. Neither the Depositary nor the Company nor any of their respective directors, officers, employees, agents or affiliates shall be liable for any action or nonaction by it in reliance upon the advice of or information from legal counsel, accountants, any person presenting Shares for deposit, any Owner or Holder, or any other person believed by it in good faith to be competent to give such advice or information. Neither the Depositary nor the Company nor any of their respective directors, officers, employees, agents or affiliates shall be liable for the failure by any Owner or Holder to obtain the benefits of credits on the basis of non-U.S. tax paid against such Owner or Holder’s income tax liability. Neither the Depositary nor the Company nor any of their respective directors, officers, employees, agents or affiliates shall incur any liability for any tax consequences that may be incurred by Owners or Holders on account of their ownership of American Depositary Shares. 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 a 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. The Depositary shall not be liable for the acts or omissions of any securities depository, clearing agency or settlement system in connection with or arising out of book-entry settlement of Deposited Securities or otherwise, provided such acts or omissions are not the direct result of the negligence or willful misconduct of the Depositary. The Depositary shall not be responsible for any failure to carry out any instructions to vote any of the Deposited Securities or for the manner in which any such vote is cast or the effect of any such vote, provided that any such action or nonaction is in good faith.

No disclaimer of liability under the Securities Act of 1933 is intended by any provision of the Deposit Agreement.

19.	RESIGNATION AND REMOVAL OF THE DEPOSITARY; APPOINTMENT OF SUCCESSOR CUSTODIAN.

The Depositary may at any time resign as Depositary under the Deposit Agreement by written notice of its election so to do delivered to the Company, such resignation to take effect upon the earlier of (i) the appointment of a successor depositary and its acceptance of such appointment as provided in the Deposit Agreement or (ii) termination by the Depositary pursuant to Section 6.2 of the Deposit Agreement. The Depositary may at any time be removed by the Company by 120 days prior written notice of such removal, to become effective upon the later of (i) the 120th day after delivery of the notice to the Depositary and (ii) the appointment of a successor depositary and its acceptance of such appointment as provided in the Deposit Agreement. The Depositary in its discretion may appoint a substitute or additional custodian or custodians.

A-14

20.	AMENDMENT.

The form of the Receipts and any provisions of the Deposit Agreement may at any time and from time to time be amended by agreement between the Company and the Depositary without the consent of Owners or Holders in any respect which they may deem necessary or desirable. Any amendment which shall impose or increase any fees or charges (other than taxes and other governmental charges, registration fees, cable, telex or facsimile transmission costs, delivery costs or other such expenses), or which shall otherwise prejudice any substantial existing right of Owners, shall, however, not become effective as to outstanding American Depositary Shares until the expiration of thirty days after notice of such amendment shall have been given to the Owners of outstanding American Depositary Shares. Every Owner and Holder of American Depositary Shares, at the time any amendment so becomes effective, shall be deemed, by continuing to hold such American Depositary Shares or any interest therein, to consent and agree to such amendment and to be bound by the Deposit Agreement as amended thereby. In no event shall any amendment impair the right of the Owner to surrender American Depositary Shares and receive therefor the Deposited Securities represented thereby, except in order to comply with mandatory provisions of applicable law.

21.	TERMINATION OF DEPOSIT AGREEMENT.

The Company may terminate the Deposit Agreement by instructing the Depositary to mail notice of termination to the Owners of all American Depositary Shares then outstanding at least 30 days prior to the termination date included in such notice. The Depositary may likewise terminate the Deposit Agreement, if at any time 60 days shall have expired after the Depositary delivered to the Company a written resignation notice and if a successor depositary shall not have been appointed and accepted its appointment as provided in the Deposit Agreement; in such case the Depositary shall mail a notice of termination to the Owners of all American Depositary Shares then outstanding at least 30 days prior to the termination date. On and after the date of termination, the Owner of American Depositary Shares will, upon (a) surrender of such American Depositary Shares, (b) payment of the fee of the Depositary for the surrender of American Depositary Shares referred to in Section 2.5, and (c) payment of any applicable taxes or governmental charges, be entitled to delivery, to him or upon his order, of the amount of Deposited Securities represented by those American Depositary Shares. If any American Depositary Shares shall remain outstanding after the date of termination, the Depositary thereafter shall discontinue the registration of transfers of American Depositary Shares, shall suspend the distribution of dividends to the Owners thereof, and shall not give any further notices or perform any further acts under the Deposit Agreement, except that the Depositary shall continue to collect dividends and other distributions pertaining to Deposited Securities, shall sell rights and other property as provided in the Deposit Agreement, and shall continue to deliver Deposited Securities, together with any dividends or other distributions received with respect thereto and the net proceeds of the sale of any rights or other property, upon surrender of American

A-15

Depositary Shares (after deducting, in each case, the fee of the Depositary for the surrender of American Depositary Shares, any expenses for the account of the Owner of such American Depositary Shares in accordance with the terms and conditions of the Deposit Agreement, and any applicable taxes or governmental charges). At any time after the expiration of four months from the date of termination, the Depositary may sell the Deposited Securities then held under the Deposit Agreement and may thereafter hold uninvested the net proceeds of any such sale, together with any other cash then held by it thereunder, unsegregated and without liability for interest, for the pro rata benefit of the Owners of American Depositary Shares that have not theretofore been surrendered, such Owners thereupon becoming general creditors of the Depositary with respect to such net proceeds. After making such sale, the Depositary shall be discharged from all obligations under the Deposit Agreement, except to account for such net proceeds and other cash (after deducting, in each case, the fee of the Depositary for the surrender of American Depositary Shares, any expenses for the account of the Owner of such American Depositary Shares in accordance with the terms and conditions of the Deposit Agreement, and any applicable taxes or governmental charges). Upon the termination of the Deposit Agreement, the Company shall be discharged from all obligations under the Deposit Agreement except for its obligations to the Depositary with respect to indemnification, charges, and expenses.

22.	DTC DIRECT REGISTRATION SYSTEM AND PROFILE MODIFICATION SYSTEM.

(a) Notwithstanding the provisions of Section 2.4 of the Deposit Agreement, the parties acknowledge that the Direct Registration System (“DRS”) and Profile Modification System (“Profile”) shall apply to uncertificated American Depositary Shares upon acceptance thereof to DRS by DTC. DRS is the system administered by DTC pursuant to which the Depositary may register the ownership of uncertificated American Depositary Shares, which ownership shall be evidenced by periodic statements issued by the Depositary to the Owners entitled thereto. Profile is a required feature of DRS which allows a DTC participant, claiming to act on behalf of an Owner, to direct the Depositary to register a transfer of those American Depositary Shares to DTC or its nominee and to deliver those American Depositary Shares to the DTC account of that DTC participant without receipt by the Depositary of prior authorization from the Owner to register such transfer.

(b) In connection with and in accordance with the arrangements and procedures relating to DRS/Profile, the parties understand that the Depositary will not verify, determine or otherwise ascertain that the DTC participant which is claiming to be acting on behalf of an Owner in requesting registration of transfer and delivery described in subsection (a) has the actual authority to act on behalf of the Owner (notwithstanding any requirements under the Uniform Commercial Code). For the avoidance of doubt, the provisions of Sections 5.3 and 5.8 of the Deposit Agreement shall apply to the matters arising from the use of the DRS. The parties agree that the Depositary’s reliance on and compliance with instructions received by the Depositary through the DRS/Profile System and in accordance with the Deposit Agreement, shall not constitute negligence or bad faith on the part of the Depositary.

A-16

EACH PARTY TO THE DEPOSIT AGREEMENT (INCLUDING, FOR AVOIDANCE OF DOUBT, EACH OWNER AND HOLDER) THEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY SUIT, ACTION OR PROCEEDING AGAINST THE COMPANY AND/OR THE DEPOSITARY DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THE SHARES OR OTHER DEPOSITED SECURITIES, THE AMERICAN DEPOSITARY SHARES OR THE RECEIPTS, THE DEPOSIT AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREIN OR THEREIN, OR THE BREACH HEREOF OR THEREOF, INCLUDING WITHOUT LIMITATION ANY QUESTION REGARDING EXISTENCE, VALIDITY OR TERMINATION (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY).

To the extent that the Company or any of its properties, assets or revenues may have or hereafter become entitled to, or have attributed to it, any right of immunity, on the grounds of sovereignty or otherwise, from any legal action, suit or proceeding, from the giving of any relief in any respect thereof, 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, or other legal process or proceeding for the giving of any relief or for the enforcement of any judgment, in any jurisdiction in which proceedings may at any time be commenced, with respect to its obligations, liabilities or any other matter under or arising out of or in connection with the Shares or Deposited Securities, the American Depositary Shares, the Receipts or the Deposit Agreement, the Company, to the fullest extent permitted by law, hereby irrevocably and unconditionally waives, and agrees not to plead or claim, any such immunity and consents to such relief and enforcement.

23.	DISCLOSURE OF INTERESTS.

A-17

Notwithstanding any other provision of the Deposit Agreement, each Owner and Holder agrees to comply with requests from the Company pursuant to applicable law, the rules and requirements of any stock exchange on which the American Depositary Shares are, or will be, registered, traded or listed, the rules and requirements of any clearing system through which transactions in the American Depositary Shares may be settled or the articles of association of the Company, as in effect from time to time, to provide information, inter alia, as to the capacity in which such Owner or Holder owns American Depositary Shares (and Shares as the case may be) and regarding the identity of any other person(s) interested in such American Depositary Shares (and Shares, as the case may be) and the nature of such interest and various other matters, whether or not they are Owners or Holders at the time of such request. The Depositary shall provide reasonable assistance to the Company, at the Company’s request and expense, in obtaining information sought by the Company pursuant to this Section 3.4.
