     Title to a Receipt (and to the American Depositary Shares evidenced thereby), when properly endorsed or accompanied by proper instruments of transfer, shall be transferable by delivery with the same effect as in the case of a negotiable instrument; provided, however, that the Depositary, notwithstanding any notice to the contrary, may treat the Owner thereof 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. Neither the Depositary nor the Issuer will have any obligation or be subject to any liability under this Deposit Agreement to any holder of a Receipt unless such holder is the Owner thereof.

     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 the Custodian hereunder, accompanied by any appropriate instrument or instruments of 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 execute and deliver to, or upon the written order of, the person or persons stated in such order, a Receipt or Receipts for 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

9

necessary approval has been granted by the Central Bank or any governmental body in Brazil which 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 Issuer 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.

          At the request and risk and expense of any person proposing to deposit Shares, and for the account of such person, the Depositary may receive certificates for Shares to be deposited, together with the other instruments herein specified, for the purpose of forwarding such Share certificates to the Custodian for deposit hereunder.

          Upon each delivery to the Custodian of a certificate or certificates for Shares to be deposited hereunder, together with the other documents above specified, the Custodian shall, as soon as transfer and recordation can be accomplished, present such certificate or certificates to the Issuer or the Foreign Registrar, if applicable, for transfer and recordation of the Shares being deposited in the name of the Depositary or its nominee or the Custodian or its nominee.

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

10

     SECTION 2.3 Execution and Delivery of Receipts.

          Upon receipt by the Custodian of any deposit pursuant to Section 2.2 hereunder (and in addition, if the transfer books of the Issuer or the Foreign Registrar, if applicable, are open, the Depositary may in its sole discretion require a proper acknowledgment or other evidence from the Issuer that any Deposited Securities have been recorded upon the books of the Issuer or the Foreign Registrar, if applicable, in the name of the Depositary or its nominee or the Custodian or its nominee), together with the other documents required as above specified, the Custodian shall notify the Depositary of such deposit and the person or persons to whom or upon whose written order a Receipt or Receipts are deliverable in respect thereof and the number of American Depositary Shares to be evidenced thereby. 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. Upon receiving such notice from the Custodian, or upon the receipt of Shares by the Depositary, the Depositary, subject to the terms and conditions of this Deposit Agreement, shall execute and deliver at its Corporate Trust Office, to or upon the order of the person or persons entitled thereto, a Receipt or Receipts, registered in the name or names and evidencing any authorized number of American Depositary Shares requested by such person or persons, but only upon payment to the Depositary of the fees and expenses of the Depositary for the execution and delivery of such Receipt or Receipts 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 Transfer of Receipts; Combination and Split-up of Receipts.

          The Depositary, subject to the terms and conditions of this Deposit Agreement, shall register transfers of Receipts on its transfer books from time to time, upon any surrender of a Receipt, by the Owner in person or by a duly authorized attorney, properly endorsed or accompanied by proper instruments of transfer, and duly stamped as

11

may be required by the laws of the State of New York and of the United States. Thereupon the Depositary shall execute a new Receipt or Receipts and deliver the same to or upon the order of the person entitled thereto.

          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 may appoint, with the approval of the Issuer (such approval not to be unreasonably withheld), one or more co-transfer agents for the purpose of effecting transfers, 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 Receipts and will be entitled to protection and indemnity to the same extent as the Depositary. Each co-transfer agent appointed under this Section 2.4 (other than the Depositary) shall give notice in writing to the Issuer accepting such appointment and agreeing to abide by the applicable terms of this Deposit Agreement.

     SECTION 2.5 Surrender of Receipts and Withdrawal of Shares.

          Upon surrender at the Corporate Trust Office of the Depositary of a Receipt for the purpose of withdrawal of the Deposited Securities represented by the American Depositary Shares evidenced by such Receipt, and upon payment of the fee of the Depositary for the surrender of Receipts 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

12

Deposit Agreement, the Owner of such Receipt shall be entitled to delivery, to him or upon his order, of the amount of Deposited Securities at the time represented by the American Depositary Shares evidenced by such Receipt. Delivery of such Deposited Securities may be made by the delivery of (a) Shares in the name of such Owner or as ordered by him or by certificates properly endorsed or accompanied by proper instruments of transfer to such Owner or as ordered by him and (b) any other securities, property and cash to which such Owner is then entitled in respect of such Receipts to such Owner or as ordered by him. 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 transfer in blank, and if the Depositary so requires, the Owner thereof shall 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 principal São Paulo, Brazil office of the 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 American Depositary Shares evidenced by such Receipt, 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 the American Depositary Shares evidenced by such Receipt, 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 a Receipt, and for the account of such Owner, the Depositary shall direct the Custodian to forward

13

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 American Depositary Shares evidenced by such Receipt 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 Execution and Delivery, Transfer and Surrender of Receipts.

          As a condition precedent to the execution and delivery, registration of transfer, split-up, combination or surrender 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 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 such reasonable regulations the Depositary may establish consistent with the provisions of this Deposit Agreement, including, without limitation, this Section 2.6.

          The delivery of Receipts against deposits of Shares generally or against deposits of particular Shares may be suspended, or the deposit of Shares may be refused, or the transfer of Receipts in particular instances may be refused, or the registration of transfer, split-up or combination of outstanding Receipts 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 Issuer at any time or from time to time because of any requirement of law or of any government or

14

governmental body or commission, or under any provision of this Deposit Agreement, or for any other reason, subject to the provisions of Section 7.7 hereof. Notwithstanding any other provision of this Deposit Agreement or the Receipts, the surrender of outstanding Receipts 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 Issuer 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 United States, Brazilian or other foreign laws or governmental regulations relating to the Receipts or to the withdrawal of the Deposited Securities, and (iv) other circumstances specifically contemplated by Section I.A.(1) of the General Instructions to Form F-6 (as such General Instructions may be amended from time to time). Without limitation of the foregoing, the Depositary shall not knowingly accept for deposit under this Deposit Agreement any Shares required to be registered under the provisions of the Securities Act, unless a registration statement is in effect as to such Shares.

     SECTION 2.7 Lost Receipts, etc.

          In case any Receipt shall be mutilated, destroyed, lost or stolen, the Depositary shall 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 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.

15

     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 Receipts.

          Unless requested in writing by the Issuer to cease doing so, the Depositary may, notwithstanding Section 2.3 hereof, execute and deliver Receipts prior to the receipt of Shares pursuant to Section 2.2 (“Pre-Release”). The Depositary may, pursuant to Section 2.5, deliver Shares upon the receipt and cancellation of Receipts which have been Pre-Released, whether or not such cancellation is prior to the termination of such Pre-Release or the Depositary knows that such Receipt has been Pre-Released. The Depositary may receive Receipts 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 Receipts are to be delivered (the “Pre-Releasee”) that the Pre-Releasee, or its customer, (i) owns the Shares or Receipts to be remitted, as the case may be, (ii) assigns all beneficial rights, title and interest in such Shares or Receipts, as the case may be, to the Depositary in its capacity as such and for the benefit of the Owners, and (iii) will not take any action with respect to such Shares or Receipts, as the case may be, that is inconsistent with the transfer of beneficial ownership (including, without the consent of the Depositary, disposing of such Shares or Receipts, as the case may be), other than in satisfaction of such Pre-Release, (b) at all times fully collateralized with cash, U.S. government securities or such other collateral as the Depositary determines, in good faith, will provide substantially similar liquidity and security, (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 not deposited but represented by American Depositary Shares outstanding at any time as a result of Pre-Releases will not normally

16

exceed thirty percent (30%) of the Shares deposited hereunder; provided, however, that the Depositary reserves the right to disregard such limit from time to time as it deems reasonably appropriate, and may, with the prior written consent of the Issuer, change such limit for purposes of general application. The Depositary will also set Dollar limits with respect to Pre-Release transactions to be entered into hereunder with any particular Pre-Releasee on a case-by-case basis as the Depositary deems appropriate. For purposes of enabling the Depositary to fulfill its obligations to the Owners under this Deposit Agreement, the collateral referred to in clause (b) above shall be held by the Depositary as security for the performance of the Pre-Releasee’s obligations to the Depositary in connection with a Pre-Release transaction, including the Pre-Releasee’s obligation to deliver Shares or Receipts upon termination of a Pre-Release transaction (and shall not, for the avoidance of doubt, constitute Deposited Securities hereunder).

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

     SECTION 2.10 Maintenance of Records.

          The Depositary agrees to maintain or cause it agents to maintain records of all Receipts surrendered and Deposited Securities withdrawn under Section 2.5, substitute Receipts delivered under Section 2.7, and of cancelled or destroyed Receipts under Section 2.8, in keeping with procedures ordinarily followed by stock transfer agents located in The City of New York or as required by the laws or regulations governing the Depositary.

17

ARTICLE 3.CERTAIN OBLIGATIONS OF OWNERS AND HOLDERS OF RECEIPTS.

     SECTION 3.1 Filing Proofs, Certificates and Other Information.

          Any person presenting Shares for deposit or any Owner or holder of a Receipt 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 Issuer 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 or as the Issuer reasonably may require upon the written request to the Depositary. The Depositary may withhold the delivery or registration of transfer of any Receipt 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. If requested in writing by the Issuer, the Depositary shall provide the Issuer, in a timely manner, with copies of the proofs, certificates or information that it receives pursuant to this Section 3.1, unless prohibited by applicable law.

     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 Receipt or any Deposited Securities represented by any Receipt, such tax or other governmental charge shall be payable by the Owner of such Receipt to the Depositary. The Depositary may refuse to effect any transfer, split-up or combination of such Receipt or any withdrawal of Deposited Securities represented by American Depositary Shares evidenced by such Receipt until such payment is made, and may withhold any dividends or other distributions made in respect of Deposited Securities, or may sell for the account of the Owner thereof any part

18

or all of the Deposited Securities represented by the American Depositary Shares evidenced by such Receipt, 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 Receipt 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 pre-emptive rights of the holders of outstanding Shares and free and clear of any lien, encumbrance, security interest, charge or adverse claim 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 Receipts evidencing American Depositary Shares representing such Shares by that person are not restricted under the Securities Act. Such representations and warranties shall survive the deposit of Shares and issuance of Receipts.

     SECTION 3.4 Disclosure of Interests.

          Notwithstanding any other provision of this Deposit Agreement, each Owner agrees to comply with requests from the Issuer pursuant to Brazilian law, the rules and requirements of the CVM and the São Paulo Stock Exchange, and any other stock exchange on which the Shares are, or will be, registered, traded or listed or the Estatuto Social, which requests are made to provide information, inter alia, as to the capacity in which such Owner owns American Depositary Shares (and Shares as the case may be) and regarding the identity of any other person interested in such American Depositary Shares and the nature of such interest and various other matters, whether or not they are Owners at the time of such requests. The Depositary agrees to use its reasonable efforts to comply with the reasonable written instructions of the Issuer to forward such requests

19

from the Issuer to the Owners and to forward to the Issuer any such responses to such requests received by the Depositary. Except for the forwarding of any such requests and responses as described in the previous sentence, the Depositary shall not be liable for any action or inaction by it in accordance with this Section 3.4.

     SECTION 3.5 Delivery of Information to the CVM.

          Each of the Depositary and the Issuer hereby confirms to the other that for as long as this Deposit Agreement is in effect, it shall furnish the CVM and the Central Bank, at any time and within the period that may be determined, with any information and documents related to the American Depositary Receipt program and the Receipts issued hereunder. In the event that the Depositary or the Custodian shall be advised in writing by reputable independent Brazilian counsel that the Depositary or Custodian reasonably could be subject to criminal, or material, as reasonably determined by the Depositary, civil, liabilities as a result of the Issuer having failed to provide such information or documents reasonably available only through the Issuer, the Depositary shall have the right to terminate this Deposit Agreement, upon at least 15 days’ prior notice to the Owners and the Issuer, and the Depositary shall not be subject to any liability hereunder on account of such termination or such determination. The effect of any such termination of this Deposit Agreement shall be as provided in Section 6.2.

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, as promptly as practicable, the amount thus received (net of the fees and expenses of the Depositary as provided in Section 5.9 hereof, if applicable) to the Owners entitled thereto,

20

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 Issuer 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, the amount distributed to the Owner of the Receipts evidencing 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 Issuer or its agent will remit to the appropriate governmental agency in Brazil all amounts withheld and owing to such agency. The Depositary will forward to the Issuer or its agent such information from its records as the Issuer may reasonably request to enable the Issuer or its agent to file necessary reports with governmental agencies, and the Depositary or the Issuer or its agent may file any such reports necessary to obtain benefits under the applicable tax treaties for the Owners of Receipts.

     SECTION 4.2 Distributions Other Than Cash, Shares or Rights.

          Subject to the provisions of Section 4.11 and Section 5.9, whenever the Depositary shall receive any distribution other than a distribution described in Sections 4.1, 4.3 or 4.4, the Depositary shall as promptly as practicable 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

21

(including, but not limited to, any requirement that the Issuer 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 in order to be distributed to Owners or holders) the Depositary deems such distribution not to be feasible, the Depositary may, after Consultation with the Issuer, 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. To the extent such securities or property or the net proceeds thereof are not distributed to owners as provided in this Section 4.2, the same shall constitute Deposited Securities and each American Depositary Share shall thereafter also represent its proportionate interest in such securities, property or net proceeds.

     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 shall if the Issuer shall so request, distribute to the Owners of outstanding Receipts entitled thereto, in proportion to the number of American Depositary Shares representing such Deposited Securities held by them respectively, additional Receipts evidencing 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 this Deposit Agreement with respect to the deposit of Shares and the issuance of American Depositary Shares evidenced by Receipts, including the withholding of any tax or other governmental charge as provided in Section 4.11 and the payment of fees of the Depositary as provided in Section 5.9. In lieu of delivering Receipts for fractional American Depositary Shares in any such case,

22

the Depositary shall sell the amount of Shares represented by the aggregate of such fractions and distribute the net proceeds, all in the manner and subject to the conditions described in Section 4.1. If additional Receipts are not so distributed, each American Depositary Share shall thenceforth also represent the additional Shares distributed upon the Deposited Securities represented thereby.

     SECTION 4.4 Rights.

          In the event that the Issuer 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, after Consultation with the Issuer, 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 Owners or to 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 Issuer to the Depositary that (a) the Issuer has elected in its sole discretion to permit such

23

rights to be exercised and (b) such Owner has executed such documents as the Issuer 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 (i) instruction from such Owner pursuant to such warrants or other instruments to the Depositary to exercise such rights, (ii) 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 (iii) 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 Issuer 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, execute and deliver Receipts to such Owner. In the case of a distribution pursuant to the second paragraph of this section, such Receipts shall be legended in accordance with applicable U.S. laws, and shall be subject to the appropriate restrictions on sale, deposit, cancellation, and transfer under such 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

24

any distinctions among such Owners because of exchange restrictions or the date of delivery of any Receipt 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 with respect to a distribution to Owners or are registered under the provisions of the Securities Act; provided, that nothing in this Deposit Agreement shall create any obligation on the part of the Issuer to file a registration statement with respect to any such rights or securities. If an Owner of Receipts requests distribution of warrants or other instruments, notwithstanding that there has been no such registration under the Securities Act, the Depositary shall not effect such distribution unless it has received an opinion from recognized counsel in the United States for the Issuer upon which the Depositary may rely that such distribution to such Owner is exempt from such registration.

     The Depositary shall not 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 convert or cause to be converted, as promptly as practicable, by sale or in any other manner that it may determine in accordance with applicable law, such Foreign Currency into Dollars, and such Dollars shall be distributed to the Owners entitled thereto or, if the

25

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, as applicable, 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 Receipt 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 reasonable 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, subject to applicable law, 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

26

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 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 receive notice of any meeting of holders of Shares or other Deposited Securities, the Depositary shall 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 or (ii) entitled to give instructions for the exercise of voting rights at any such meeting, 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.

          As of the date of this Deposit Agreement, the Shares do not give the holders thereof any voting rights, except in certain limited circumstances. If in the future the terms of the Shares should be revised or amended to provide for voting rights, or should such Shares otherwise obtain any voting rights, then, upon receipt of notice of any meeting of holders of Shares or other Deposited Securities from the Issuer, if requested in writing by the Issuer the Depositary shall, as soon as practicable thereafter, mail to the Owners a notice,

27

the form of which notice shall be in the sole discretion of the Depositary, which shall contain (a) such information as is contained in such notice of meeting, and (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 the laws of Brazil and of the Estatuto Social and the provisions of the 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 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 Issuer. 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 “Instruction Date”) the Depositary shall endeavor, in so far as practicable, to vote or cause to be voted the amount of Shares or other Deposited Securities represented by the American Depositary Shares evidenced by such Receipt 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 no instructions are received by the Depositary from any Owner with respect to any of the Deposited Securities represented by the American Depositary Shares evidenced by such Owner’s Receipts 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 Issuer with respect to such Deposited Securities and the Depositary shall give a discretionary proxy to a person designated by the Issuer to vote such Deposited Securities, provided, that no such instruction shall be given with respect to any matter as to which the Issuer informs the Depositary (and the Issuer agrees to provide such information as promptly as practicable in writing) that (x) the Issuer does

28

not wish such proxy given, (y) substantial opposition exists or (z) such matter materially and adversely affects the rights of holders of Shares.

          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 Date to ensure that the Depositary will vote the Shares or Deposited Securities in accordance with the provisions set forth in the preceding paragraph.

     SECTION 4.8 Changes Affecting Deposited Securities.

          In circumstances where the provisions of Section 4.3 do not apply, 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 Issuer or to which it is a party, any securities which shall be received by the Depositary or the Custodian in exchange for or in conversion of or in respect of Deposited Securities, shall be treated as new Deposited Securities under this Deposit Agreement, and American Depositary Shares shall thenceforth represent, in addition to the existing Deposited Securities, if any, the new Deposited Securities so received in exchange or conversion, unless additional Receipts are delivered pursuant to the following sentence. In any such case the Depositary may, and shall if the Issuer shall so request, execute and deliver additional Receipts 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 soliciting material, received from the Issuer 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 Issuer. The Depositary shall also, upon written request, send

29

to the Owners copies of such reports furnished by the Issuer pursuant to Section 5.6. Any such reports and communications, including any such proxy soliciting material, furnished to the Depositary by the Issuer shall be furnished in English.

     SECTION 4.10 Lists of Owners.

          Promptly upon request by the Issuer, the Depositary shall, at the expense of the Issuer, furnish to it a list, as of a recent date, of the names, addresses and holdings of American Depositary Shares by all persons in whose names Receipts are registered on the books of the Depositary.

     SECTION 4.11 Withholding.

          In the event that the Depositary 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 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 entitled thereto in proportion to the number of American Depositary Shares held by them respectively. The Depositary will forward to the Issuer or its agent such information from its records as the Issuer may reasonably request to enable the Issuer or its agents to file necessary reports with governmental authorities or agencies. The Depositary, the Custodian or the Issuer and its agents may, but shall not be obligated to, file such reports as are necessary to reduce or eliminate applicable taxes on dividends and on other distributions in respect of Deposited Securities under applicable tax treaties or laws for the Owners. Owners of American Depositary Shares 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 certificates and to make such

30

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 Owners shall indemnify the Depositary, the Issuer, 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.

     SECTION 4.12 Additional Information.

31

          The Depositary may close the transfer books, at any time or from time to time, when deemed expedient by it in connection with the performance of its duties hereunder after Consultation with the Issuer if such closure is outside the ordinary course of business.

          The Issuer shall have the right, upon reasonable request, to inspect the transfer and registration records of the Depositary relating to the Receipts, to make copies thereof and to request the Depositary and registrar in writing to supply copies of such portions of such records at the Issuer’s expense as the Issuer may reasonably request.

32

penalty on account of, doing or performing any act or thing which by the terms of this Deposit Agreement or the Deposited Securities it is provided shall be done or performed; nor shall the Depositary or the Issuer or any of their respective directors, officers, employees, agents or affiliates incur any liability to any Owner or holder of any Receipt by reason of any non-performance or delay, caused as aforesaid, in the performance of any act or thing which by the terms of this Deposit Agreement it is provided shall or may be done or performed, or by reason of any exercise of, or failure to exercise, any discretion provided for in this Deposit Agreement. Where, by the terms of a distribution pursuant to Sections 4.1, 4.2, or 4.3 of this Deposit Agreement, or an offering or distribution pursuant to Section 4.4 of this Deposit Agreement, or for any other reason, such distribution or offering may not be made available to Owners, 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.

     SECTION 5.3 Obligations of the Depositary, the Custodian and the Issuer.

33

          Neither the Depositary nor the Issuer 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 Receipts, which in its opinion may involve it in expense or liability, unless indemnity satisfactory to it against all expense and liability shall be furnished as often as may be required, and the Custodian shall not be under any obligation whatsoever with respect to such proceedings, the responsibility of the Custodian being solely to the Depositary.

          Neither the Depositary nor the Issuer shall be liable for any action or inaction by it in reliance upon the advice of or information from legal counsel, accountants, any person presenting Shares for deposit, any Owner or any other person believed by it in good faith to be competent to give such advice or information.

          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.

          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 inaction is in good faith.

          The Depositary, its controlling persons and its agents, the Custodian and the Issuer, its controlling persons and its agents may rely and shall be protected in acting

          In case at any time the Depositary acting hereunder shall resign or be removed, the Issuer shall use its 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 execute and deliver to its predecessor and to the Issuer an instrument in writing accepting its appointment hereunder, and thereupon such successor depositary, without any further act or deed, shall become fully vested with all the rights, powers, duties and obligations of its predecessor; but such predecessor, nevertheless, upon payment of all sums due it and on the written request of the Issuer shall execute and deliver an instrument transferring to such successor all rights and powers of such predecessor hereunder, shall duly assign, transfer and deliver all right, title and interest in the Deposited Securities to such successor, and shall deliver to such

35

successor a list of the Owners of all outstanding Receipts. Any such successor depositary shall promptly mail notice of its appointment to the Owners.

The Depositary may discharge the Custodian any time upon notice to the Custodian being discharged. Whenever the Depositary in its discretion determines that it is in the best interest of the Owners to do so, it may appoint a substitute custodian, which shall thereafter be the Custodian hereunder.

The substitute custodian shall deliver to the Depositary, forthwith upon its appointment, an acceptance of such appointment satisfactory in form and substance to the Depositary. The Depositary agrees with the Issuer that at no time shall there be more than one Custodian acting in connection with this Deposit Agreement. The Depositary agrees to promptly notify the Issuer of the appointment of a substitute Custodian.

     SECTION 5.6 Notices and Reports.

          On or before the first date on which the Issuer 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 in respect of any cash or other distributions or the offering of any rights, the Issuer agrees to transmit to the Depositary and the Custodian a copy of the notice thereof in the form given or to be given to holders of Shares or other Deposited Securities.

          The Issuer will arrange for the translation into English and the prompt transmittal by the Issuer to the Depositary and the Custodian of such notices and any other reports and communications which are made generally available by the Issuer to holders of its Shares. If requested in writing by the Issuer, the Depositary will arrange for the mailing of copies of such notices, reports and communications to all Owners. The Issuer will timely provide the Depositary with the quantity of such notices, reports, and communications, as requested by the Depositary from time to time, in order for the Depositary to effect such mailings.

37

     SECTION 5.7 Distribution of Additional Shares, Rights, etc.

          The Issuer agrees that in the event of any issuance or distribution of (1) additional Shares, (2) rights to subscribe for Shares, (3) securities convertible into Shares, or (4) rights to subscribe for such securities, (each a “Distribution”) the Issuer will notify the Depositary of such Distribution prior to making the Distribution and, if requested by the Depositary, will furnish to the Depositary as soon as practicable a written opinion from recognized U.S. counsel for the Issuer, stating whether or not the Distribution requires a registration statement under the Securities Act to be in effect prior to making such Distribution available to Owners entitled thereto. If in the opinion of such counsel a registration statement is required, such counsel shall furnish to the Depositary a written opinion as to whether or not there is a registration statement in effect which will cover such Distribution.

          The Issuer agrees with the Depositary that neither the Issuer nor any company controlled by, controlling or under common control with the Issuer will at any time deposit any Shares, either originally issued or previously issued and reacquired by the Issuer or any such affiliate, unless a registration statement is in effect as to such Shares under the Securities Act. Notwithstanding any other provision in this Deposit Agreement, nothing in this Deposit Agreement shall be deemed to obligate the Issuer to file any registration statement in respect of any proposed transaction.

     SECTION 5.8 Indemnification.

          The Issuer agrees to indemnify the Depositary, its directors, officers, employees, agents and affiliates and the Custodian against, and hold each of them harmless from, any liability or expense (including, but not limited to, the reasonable fees and expenses of counsel) which may arise out of any registration with the Commission of Receipts, American Depositary Shares or Deposited Securities or the offer or sale thereof in the United States or out of acts performed or omitted, in accordance with the

38

provisions of this Deposit Agreement and of the Receipts, as the same may be amended, modified or supplemented from time to time, (i) by either the Depositary or the Custodian or their respective directors, employees, agents and affiliates, except for any liability or expense arising out of the negligence or bad faith of the Depositary or the Custodian and except to the extent that such liability or expense arises out of information relating to the Depositary or the Custodian, as applicable, furnished in writing to the Issuer by the Depositary expressly for use in any registration statement, proxy statement, prospectus (or placement memorandum) or preliminary prospectus (or preliminary placement memorandum) relating to the Shares, and not altered or omissions from such information or (ii) by the Issuer or any of its directors, employees, agents and affiliates.

          The indemnities contained in the preceding paragraph shall not extend to any liability or expense which arises solely and exclusively out of a Pre-Release (as defined in Section 2.9) of a Receipt or Receipts in accordance with Section 2.9 and which would not otherwise have arisen had such Receipt or Receipts 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 a Receipt or Receipts 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 (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 (i) information relating to the Depositary or any Custodian (other than the Issuer), as applicable, furnished in writing and not materially changed or altered by the Issuer expressly for use in any of the foregoing documents, or, (ii) if such information is provided, the failure to state a material fact necessary to make the information provided not misleading.

39

          The Depositary agrees to indemnify the Issuer, its directors, officers, employees, agents and affiliates and hold them harmless from any liability or expense (including, but not limited, to 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 the negligence or bad faith of either of them.

          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 or 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

40

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 provided is monetary damages that are paid in full by the party seeking the settlement. 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.

          The obligation set forth in this Section 5.8 shall survive the termination of this Deposit Agreement and the succession or substitution of any Indemnitee.

     SECTION 5.9 Charges of Depositary.

          The Issuer agrees to pay the fees, reasonable expenses and out-of-pocket charges of the Depositary and those of any Registrar only in accordance with agreements in writing entered into between the Depositary and the Issuer from time to time. The Depositary shall present its statement for such charges and expenses to the Issuer once every three months. Except as set forth in clause (8) below, the charges and expenses of the Custodian are for the sole account of the Depositary.

41

          The following charges shall be incurred by any party depositing or withdrawing Shares or by any party surrendering Receipts or to whom Receipts are issued (including, without limitation, issuance pursuant to a stock dividend or stock split declared by the Issuer or an exchange of stock regarding the Receipts or Deposited Securities or a distribution of Receipts pursuant to Section 4.3), or by Owners, as applicable: (1) taxes and other governmental charges; (2) such registration fees as may from time to time be in effect for the registration of transfers of Shares generally on the Share register of the Issuer or Foreign Registrar (or any other appointed agent of the Issuer for transfer and registration of the Shares) and applicable to transfers of Shares to or from the name of the Depositary or its nominee or the Custodian or its nominee on the making of deposits or withdrawals hereunder; (3) such cable, telex and facsimile transmission expenses as are expressly provided in this Deposit Agreement to be at the expense of the person depositing or withdrawing Shares or Owners of American Depositary Shares; (4) such expenses as are incurred by the Depositary in the conversion of Foreign Currency pursuant to Section 4.5; (5) a fee of $5.00 or less per 100 American Depositary Shares (or portion thereof) for the execution and delivery of Receipts pursuant to Section 2.3, 4.3 or 4.4 and the surrender of Receipts pursuant to Section 2.5 or 6.2; (6) a fee of $.02 or less per American Depositary Share (or portion thereof) for any cash distribution made pursuant to this Deposit Agreement, including, but not limited to Sections 4.1 through 4.4 hereof, to the extent permitted by the rules of any securities exchange on which the American Depositary Shares may be listed for trading; (7) a fee for the distribution of securities pursuant to Section 4.2, such fee being in an amount equal to the fee for the execution and delivery of American Depositary Shares referred to above which would have been charged as a result of the deposit of such securities (for purposes of this clause 7 treating all such securities as if they were Shares) but which securities are instead distributed by the Depositary to Owners; and (8) any other charge payable by the Depositary, any of the Depositary’s agents, including the Custodian, or the

42

agents of the Depositary’s agents in connection with the servicing of Shares or other Deposited Securities (which charge shall be assessed against Owners as of the date or dates set by the Depositary in accordance with Section 4.6 and shall be payable at the sole discretion of the Depositary by billing such Owners for such charge or by deducting such charge from one or more cash dividends or other cash distributions).

          The Depositary, subject to Section 2.9 hereof, may own and deal in any class of securities of the Issuer and its affiliates and in Receipts.

     SECTION 5.10 Retention of Depositary Documents.

          The Depositary is authorized to destroy those documents, records, bills and other data compiled during the term of this Deposit Agreement at the times permitted by the laws or regulations governing the Depositary unless the Issuer requests that such papers be retained for a longer period or turned over to the Issuer or to a successor depositary.

     SECTION 5.11 Exclusivity.

          Subject to the rights of the Issuer under Section 5.4, the Issuer agrees not to appoint any other depositary for issuance of American Depositary Receipts so long as The Bank of New York is acting as Depositary hereunder.

     SECTION 5.12 List of Restricted Securities Owners.

          From time to time, the Issuer shall provide to the Depositary a list setting forth, to the actual knowledge of the Issuer, those persons or entities who beneficially own Restricted Securities and the Issuer shall update that list on a regular basis. The Issuer agrees to advise in writing each of the persons or entities so listed that such Restricted Securities are ineligible for deposit hereunder. The Depositary may rely on

43

such a list or update but shall not be liable for any action or omission made in reliance thereon.

ARTICLE 6. AMENDMENT AND TERMINATION.

     SECTION 6.1 Amendment.

          The form of the Receipts and any provisions of this Deposit Agreement may at any time and from time to time be amended by written agreement between the Issuer and the Depositary without the consent of Owners and 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 Receipts until the expiration of 30 days after notice of such amendment shall have been given to the Owners of outstanding Receipts. Every Owner at the time any amendment so becomes effective shall be deemed, by continuing to hold such Receipt, to consent and agree to such amendment and to be bound by this Deposit Agreement as amended thereby. In no event shall any amendment impair the right of the Owner of any Receipt to surrender such Receipt and receive therefor the Deposited Securities represented thereby, except in order to comply with mandatory provisions of applicable law.

     SECTION 6.2 Termination.

          The Depositary shall at any time at the direction of the Issuer terminate this Deposit Agreement by mailing notice of such termination to the Owners of all Receipts then outstanding at least 90 days prior to the date fixed in such notice for such termination. The Depositary may likewise terminate this Deposit Agreement by mailing notice of such termination to the Issuer and the Owners of all Receipts then outstanding if

44

at any time 90 days shall have expired after the Depositary shall have delivered to the Issuer a written notice of its election to resign and a successor depositary shall not have been appointed and accepted its appointment as provided in Section 5.4. On and after the date of termination, the Owner of a Receipt will, upon (a) surrender of such Receipt at the Corporate Trust Office of the Depositary, (b) payment of the fee of the Depositary for the surrender of Receipts 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 the American Depositary Shares evidenced by such Receipt. If any Receipts shall remain outstanding after the date of termination, the Depositary thereafter shall discontinue the registration of transfers of Receipts, shall suspend the distribution of dividends to the Owners thereof, and shall not give any further notices or perform any further acts under this 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 this 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, in exchange for Receipts surrendered to the Depositary (after deducting, in each case, the fee of the Depositary for the surrender of a Receipt, any expenses for the account of the Owner of such Receipt in accordance with the terms and conditions of this Deposit Agreement, and any applicable taxes or governmental charges). At any time after the expiration of one year from the date of termination, the Depositary may sell the Deposited Securities then held hereunder and may thereafter hold uninvested the net proceeds of any such sale, together with any other cash then held by it hereunder, unsegregated and without liability for interest, for the pro rata benefit of the Owners of Receipts which 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

45

under this 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 a Receipt, any expenses for the account of the Owner of such Receipt in accordance with the terms and conditions of this Deposit Agreement, and any applicable taxes or governmental charges). Upon the termination of this Deposit Agreement, the Issuer shall be discharged from all obligations under this Deposit Agreement except for its obligations to the Depositary under Sections 5.8 and 5.9 hereof.

ARTICLE 7. MISCELLANEOUS.

     SECTION 7.1 Counterparts.

          This Deposit Agreement may be executed in any number of counterparts, each of which shall be deemed an original and all of such counterparts shall constitute one and the same instrument.

          Delivery of a notice sent by mail or cable, telex or facsimile transmission shall be deemed to be effected at the time when a duly addressed letter containing the

47

The Depositary or the Issuer may, however, act upon any cable, telex or facsimile transmission received by it, notwithstanding that such cable, telex or facsimile transmission shall not subsequently be confirmed by letter as aforesaid.
