Item 10. Undertakings

The undersigned registrants hereby undertake:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof;

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering; and

(4) To file a post-effective amendment to the registration statement to include any financial statements required by Item 8.A. of Form 20-F at the start of any delayed offering or throughout a

II-2


continuous offering. Financial statements and information otherwise required by Section 10(a)(3) of the Securities Act of 1933 need not be furnished, provided, that the registrant includes in the prospectus, by means of a post-effective amendment, financial statements required pursuant to this paragraph (a)(4) and other information necessary to ensure that all other information in the prospectus is at least as current as the date of those financial statements. Notwithstanding the foregoing, with respect to registration statements on Form F-3, a post-effective amendment need not be filed to include financial statements and information required by Section 10(a)(3) of the Securities Act of 1933 or Rule 3-19 of Regulation S-X promulgated by the Securities and Exchange Commission if such financial statements and information are contained in periodic reports filed with or furnished to the Securities and Exchange Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the Form F-3.

The undersigned registrants hereby undertake that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrants have been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.

The undersigned registrants hereby undertake to file an application for the purpose of determining the eligibility of the trustee to act under subsection
(a) of Section 310 of the Trust Indenture Act in accordance with the rules and regulations prescribed by the Commission under Section 305(b)(2) of the Trust Indenture Act.

Such instrument or instruments and any such record (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the "Act" of the Holders of Securities signing such instrument or instruments or so voting at such meeting. Proof of execution of any such instrument or of a writing appointing any such agent or proxy, or of the holding by any Person of a Security shall be sufficient for any purpose of this Indenture and (subject to Section 6.01) conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section. The record of any meeting of Holders of Securities shall be proved in the manner provided in

Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also

If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities of the relevant series on such record date, or their duly designated proxies, and no other Holders, shall be entitled to take the relevant action, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders, or duly designated proxies, of the requisite principal amount of Outstanding Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent the Company from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be canceled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders, or their duly designated proxies, of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Company, at its own expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Trustee in writing and to each Holder of Securities of the relevant series in the manner set forth in Section 1.06.

Section 5.12, in each case with respect to Securities of such series. If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities of such series on such record date, or their duly designated proxies, and no other Holders, shall be entitled to join in such notice, declaration, request or direction, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders, or their duly designated proxies, of the requisite principal amount of Outstanding Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent the Trustee from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be canceled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders, or their duly designated proxies, of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Trustee, at the expense of the Company, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Company in writing and to each Holder of Securities of the relevant series in the manner set forth in Section 1.06.

With respect to any record date set pursuant to this Section, the party hereto which sets such record date may designate any day as the "Expiration Date" and from time to time may change the Expiration Date to any earlier or later day; provided that no such change shall be effective unless notice of the proposed new Expiration Date is given to the other party or parties hereto in writing, and to each Holder of Securities of the relevant series in the manner set forth in Section 1.06, on or prior to the existing Expiration Date. Notwithstanding the foregoing, no Expiration Date shall be later than the 180th

11

day after the applicable record date and, if an Expiration Date is not designated with respect to any record date set pursuant to this Section, the party or parties hereto which set such record date shall be deemed to have designated the 180th day after such record date as the Expiration Date with respect thereto.

Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder with regard to any particular Security may do so with regard to all or any part of the principal amount of such Security or by one or more duly appointed agents or proxies each of which may do so pursuant to such appointment with regard to all or any part of such principal amount.

(4) The principal amount and serial numbers of Global Securities held by any Person, and the date of holding the same, shall be proved by the Security Register.

(5) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Security shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Security.

In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice to Holders of Securities by mail, then such notification as shall be given with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder. In any case where notice to Holders of Securities is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder of a Security shall affect the sufficiency of such notice with respect to other Holders of Securities.

12

Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act that may be so modified or excluded, the provision of such Act shall be deemed to apply to this Indenture as so modified or to be excluded, as the case may be.

Unless otherwise provided as contemplated by Section 3.01 with respect to any series of Securities, any Securities of a series shall be issuable in denominations of $1,000 and any integral multiple thereof.

Section 3.03 Execution, Authentication, Delivery and Dating.

The Securities shall be executed on behalf of the Company by any Authorized Representative of the Company. The signature of any such Authorized Representative of the Company may be manual or facsimile.

Securities bearing the manual or facsimile signatures of individuals who were at any time a proper Authorized Representative of the Company shall bind the Company notwithstanding that such individuals or any of them have ceased to hold such positions prior to the authentication and delivery of such Securities or did not hold such positions at the date of such Securities.

At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series, executed by the Company to the Trustee for authentication, together with an Order for the authentication and delivery of such Securities, and the Trustee in accordance with the Order shall authenticate and deliver such Securities.

If the forms or terms of the Securities of the series have been established in or pursuant to one or more Authorizations as permitted by Sections 2.01 and 3.01, in authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive, and (subject to Section 6.01) shall be fully protected in relying upon, an Opinion of Counsel and Officers' Certificate stating,

(1) that such forms or terms have been established in conformity with the provisions of this Indenture; and

(2) that such Securities, when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company enforceable in accordance with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors' rights and to general equity principles.

The Trustee shall have the right to decline to authenticate and deliver any Securities under this Section if the Trustee, being advised in writing by counsel, determines that such action may not lawfully be taken or if the Trustee in good faith shall determine that such action would expose the Trustee to personal liability based upon the written advice of counsel.

30

The Trustee shall not be required to authenticate the Securities of any series if the issue of such Securities pursuant to this Indenture will affect the Trustee's own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee.

Notwithstanding the provisions of Section 3.01 and of the preceding paragraph, if all Securities of a series are not to be originally issued at one time, it shall not be necessary to deliver the Officer's Certificate otherwise required pursuant to Section 3.01 or the Order and Opinion of Counsel otherwise required pursuant to such preceding paragraph at or prior to the time of authentication of each Security of such series if such documents are delivered at or prior to the authentication upon original issuance of the first Security of such series to be issued.

Each Security shall be dated the date of its authentication.

No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Security to the Trustee for cancellation as provided in Section 3.09, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture.

Section 3.04 Temporary Securities.

Pending the preparation of definitive Securities of any series, the Company may execute, and upon Order the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued, in registered form and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of such Securities. A Temporary Regulation S Security shall be delivered only in compliance with the conditions set forth in Section 3.03 and this Section 3.04.

If temporary Securities of any series are issued, the Company will cause definitive Securities of that series to be prepared without unreasonable delay. After the preparation of definitive Securities of such series, the temporary Securities of such series shall be exchangeable for definitive Securities of such series upon surrender of the temporary Securities of such series at the office or agency of the Company in a Place of Payment for that series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any series, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor one or more definitive Securities of the same series, of any authorized denominations and of a like aggregate principal amount and tenor.

If Temporary Regulation S Securities of any series are issued, any such Temporary Regulation S Security shall, unless otherwise provided therein, be delivered to DTC or its nominee or the Common Depositary, in each case, for the benefit of the Euroclear Operator and Clearstream, Luxembourg, for credit to the respective accounts of the beneficial owners of such Securities (or to such other accounts as they may direct).

31

Without unnecessary delay but in any event not later than the date specified in, or determined pursuant to the terms of, any such Temporary Regulation S Security of a series (the "Exchange Date"), the Company shall deliver to the Trustee definitive Securities of that series in aggregate principal amount equal to the principal amount of such Temporary Regulation S Security executed by the Company. On or after the Exchange Date, such Temporary Regulation S Security shall be surrendered by DTC or its nominee or the Common Depositary, as the case may be, to the Trustee, as the Company's agent for such purpose, to be exchanged, in whole or from time to time in part, for definitive Securities of that series without charge, and the Trustee shall authenticate and deliver, in exchange for each portion of such Temporary Regulation S Security a like aggregate principal amount of definitive Securities of the same series of authorized denominations and of like tenor as the portion of such Temporary Regulation S Security to be exchanged; provided however, that upon such presentation by DTC or its nominee or the Common Depositary, such Temporary Regulation S Security must be accompanied by a certificate dated the Exchange Date or a subsequent date and signed by the Euroclear Operator as to the portion of such Temporary Regulation S Security held for its account then to be exchanged and a certificate dated the Exchange Date or a subsequent date and signed by Clearstream, Luxembourg as to the portion of such Temporary Regulation S Security held for its account then to be exchanged, each in the form set forth in Section 3.12(2). The definitive Securities to be delivered in exchange for any such Temporary Regulation S Security shall, unless otherwise specified in the Temporary Regulation S Security, be in or in the form of Permanent Regulation S Securities.

Unless otherwise specified in the Temporary Regulation S Security, the interest of a beneficial owner of Securities of a series in a Temporary Regulation S Security shall be exchanged on the Exchange Date for interest in a permanent global registered Security (a "Permanent Regulation S Security") of the same series and of like tenor unless, on or prior to the Exchange Date, such beneficial owner has not delivered to the Euroclear Operator or Clearstream, Luxembourg, as the case may be, a certificate in the form set forth in Section 3.12(1) dated no earlier than the Certification Date, copies of which certificate shall be available from the office of the Euroclear Operator and Clearstream, Luxembourg, the Trustee, and any Authenticating Agent appointed for such series of Securities and each Paying Agent and after the Exchange Date, the interest of a beneficial owner of Securities of a series in a Temporary Regulation S Security shall be exchanged for an interest in a Permanent Regulation S Security of the same series and of like tenor following such beneficial owner's delivery to the Euroclear Operator or Clearstream, Luxembourg, as the case may be, of a certificate in the form set forth in
Section 3.12(1) dated no earlier than the Certification Date. Unless otherwise specified in such Temporary Regulation S Security, any such exchange shall be made free of charge to the beneficial owners of such Temporary Regulation S Security.

Until exchanged in full as hereinabove provided, the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of the same series and of like tenor authenticated and delivered hereunder, except that, interest payable on a Temporary Regulation S Security on an Interest Payment Date for Securities of such series shall be payable to the Euroclear Operator and Clearstream, Luxembourg on such Interest Payment Date only upon delivery by the Euroclear Operator or Clearstream, Luxembourg to the Trustee of a certificate or certificates in the form set forth in Section 3.12(2), for credit without further interest on or after such Interest Payment Date to the respective accounts of the Persons who are the beneficial owners of such Temporary Regulation S Security on such Interest Payment Date and who have each delivered to the Euroclear Operator or Clearstream, Luxembourg, as the case may be, a certificate in the form set forth in Section 3.12(1). Any interest so received by the Euroclear Operator and Clearstream, Luxembourg and not paid as herein provided shall be returned to the Trustee immediately prior to the expiration of two years after such Interest Payment Date in order to be repaid to the Company in accordance with Section 10.03.

32

Section 3.05 Registration, Registration of Transfer and Exchange.

(1) The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in any other office or agency of the Company in a Place of Payment being herein sometimes collectively referred to as the "Security Register") in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Registered Securities and of transfers of Registered Securities. The Trustee is hereby appointed "Security Registrar" for the purpose of registering Registered Securities and transfers of Registered Securities as herein provided. Such Security Register shall distinguish between Original Securities and Exchange Securities.

Except as otherwise provided in this Section 3.05(1), upon surrender for registration of transfer of a Registered Security of any series at the office or agency in a Place of Payment for that series, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Registered Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount.

Subject to Section 3.05(2), at the option of the Holder, Registered Securities of any series may be exchanged for other Registered Securities of the same series, of any authorized denominations and of a like tenor and aggregate principal amount upon surrender of the Registered Securities to be exchanged at such office or agency. Whenever any Registered Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Registered Securities which the Holder making the exchange is entitled to receive.

All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company evidencing the same debt (subject to the provisions, if any, in the Original Securities regarding payment of Special Interest) and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange.

Every Registered Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed, by the Holder thereof or his attorney duly authorized in writing.

In the event that the Company delivers to the Trustee a copy of an Officer's Certificate certifying that a registration statement under the Securities Act with respect to an Exchange Offer relating to a particular series of Securities, if any such Exchange Offer is contemplated for such series, has been declared effective by the Commission and that the Company has offered Exchange Securities of such series to the Holders in accordance with the Exchange Offer, the Trustee shall exchange, upon request of any Holder, such Holder's Securities for Exchange Securities upon the terms set forth in the Exchange Offer.

No service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Sections 3.04, 9.06 or 11.07 not involving any transfer.

The Company shall not be required (i) to issue, register the transfer of or exchange Registered Securities of any series during a period beginning at the opening of business 15 days before any selection of Securities of that series to be redeemed and ending at the close of business on the day of the mailing of the relevant notice of redemption or (ii) to register the transfer of or exchange any

33

Registered Security so selected for redemption, in whole or in part, except the unredeemed portion of any Security being redeemed in part.

The provisions of Clauses (a), (b), (c) and (d) below shall apply only to Global Registered Securities:

(a) Each Global Security authenticated under this Indenture shall be registered in the name of the Depositary designated for such Global Security or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each such Global Security shall constitute a single Security for all purposes of this Indenture.

(b) Subject to Clause (d) below, any exchange of a Global Security for other Securities may be made in whole or in part, and all Securities issued in exchange for a Global Security or any portion thereof shall be registered in such names as the Depositary for such Global Security shall direct.

(c) Every Security authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global Security or any portion thereof, whether pursuant to this Section, Sections 3.04, 3.06, 9.06 or 11.07 or otherwise, shall be authenticated and delivered in the form of, and shall be, a Global Security, unless such Security is registered in the name of a Person other than the Depositary for such Global Security or a nominee thereof.

(d) Except as provided below, owners of beneficial interests in Global Securities will not be entitled to receive Registered Securities in their names ("Certificated Securities"). Certificated Securities shall be issued to all owners of beneficial interests in a Global Note in exchange for such interests if:

(i) The Depositary notifies the Company that it is unwilling or unable to continue as depositary for such Global Note or the Depositary ceases to be a clearing agency registered under the Exchange Act, at a time when such Depositary is required to be so registered in order to act as depositary, and in each case, and a successor depositary is not appointed by the Company within 90 days of such notice,

(ii) The Depositary executes and delivers to the Trustee and the Security Registrar an Officers' Certificate stating that such Global Note shall be so exchangeable, or

(iii) an Event of Default has occurred and is continuing and the Security Registrar has received a request from the Depositary or the Security Registrar and the Company have received a request from the Trustee.

In connection with the exchange of an entire Global Security for Certificated Securities pursuant to this Clause d, such Global Note shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and upon receipt of an Order the Trustee shall authenticate and deliver, to each beneficial owner identified by the Depositary in exchange for its beneficial interest in such Global Security, an equal aggregate principal amount of Certificated Securities of authorized denominations.

(e) Members of, or participants in, DTC or Euroclear and Clearstream, Luxembourg, as the case may be ("Agent Members"), shall have no rights under this Indenture with respect to any Global Security held on their behalf by DTC or by the Common Depositary under such

34

Global Security, and DTC or the Common Depositary, as the case may be, may be treated by the Company, the Trustee, the Paying Agent and the Security Registrar and any of their agents as the absolute owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee, the Paying Agent or the Security Registrar or any of their agents from giving effect to any written certification, proxy or other authorization furnished by DTC or the Common Depositary or impair, as between DTC or Euroclear and Clearstream, Luxembourg and their respective Agent Members, the operation of customary practices governing the exercise of the rights of an owner of a beneficial interest in any Global Security. The registered Holder of a Global Security may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action that a Holder is entitled to take under this Indenture or the Securities.

(2) Certain Transfers and Exchanges.

(a) The following provisions shall apply with respect to any proposed transfer of an interest in a Restricted Global Security: If
(i) the owner of a beneficial interest in a Restricted Global Security wishes to transfer such interest (or portion thereof) to a Non-U.S. Person pursuant to Regulation S and (ii) such Non-U.S. Person wishes to hold its interest in the Security through a beneficial interest in the Regulation S Global Security, (x) upon receipt by the Depositary and Security Registrar of:

(i) instructions from the Holder of the Restricted Global Note directing the Depositary and Security Registrar to credit or cause to be credited a beneficial interest in the Regulation S Global Security equal to the principal amount of the beneficial interest in the Restricted Global Security to be transferred, and

(ii) a Restricted Securities Certificate in the form of Annex B from the transferor,

and (y) subject to the rules and procedures of the Depositary, the Depositary and Security Registrar shall increase the Regulation S Global Security and decrease the Restricted Global Security by such amount in accordance with the foregoing.

(b) If the owner of an interest in a Regulation S Global Security wishes to transfer such interest (or any portion thereof) to a "qualified institutional buyer" as defined by and pursuant to Rule 144A prior to the expiration of the Restricted Period therefor, (x) upon receipt by the Depositary and Security Registrar of:

(i) instructions from the Holder of the Regulation S Global Security directing the Depositary and Security Registrar to credit or cause to be credited a beneficial interest in the Restricted Global Note equal to the principal amount of the beneficial interest in the Regulation S Global Security to be transferred, and

(ii) a Restricted Securities Certificate in the form of Annex B duly executed by the transferor,

and (y) in accordance with the rules and procedures of the Depositary, the Depositary and Security Registrar shall increase the Restricted Global Security and decrease the Regulation S Global Security by such amount in accordance with the foregoing.

35

(c) Other Transfers. Any transfer of Restricted Securities or Regulation S Securities not described above (other than a transfer of a beneficial interest in a Global Security that does not involve an exchange of such interest for a Certificated Note or a beneficial interest in another Global Security, which must be effected in accordance with applicable law and the rules and procedures of the Depositary, but is not subject to any procedure required by this Indenture) shall be made only upon receipt by the Security Registrar of such opinions of counsel, certificates and/or other information reasonably required by and satisfactory to it in order to ensure compliance with the Securities Act or in accordance with paragraph (3) of this Section 3.05.

(3) Securities Act Legends. Rule 144A Securities and their Successor Securities shall bear a Restricted Securities Legend, and Initial Regulation S Securities and their Successor Securities shall bear a Regulation S Legend, subject to the following:

(a) subject to the following Clauses of this Section 3.05(3), a Security or any portion thereof which is exchanged, upon registration of transfer or otherwise, for a Registered Global Security or any portion thereof shall bear the Securities Act legend borne by such Registered Global Security while represented thereby;

(b) subject to the following Clauses of this Section 3.05(3), a new Registered Security which is issued in exchange for another Security or any portion thereof, upon registration of transfer or otherwise, shall bear the Securities Act legend borne by such other Security, provided that, if such new Registered Security is required to be issued in the form of a Restricted Security, it shall bear a Restricted Securities Legend and, if such new Registered Security is so required to be issued in the form of a Regulation S Security, it shall bear a Regulation S Legend;

(c) any SEC Registered Securities shall not bear a Securities Act legend,

(d) after the applicable restricted period prescribed by Rule 144(k) under the Securities Act, a new Registered Security which does not bear a Securities Act legend may be issued in exchange for or in lieu of a Registered Security or any portion thereof which bears such a legend if the Trustee has received an Unrestricted Securities Certificate, satisfactory to the Trustee and duly executed by the Holder of such legended Security or his attorney duly authorized in writing, and after such date and receipt of such certificate, the Trustee shall authenticate and deliver such a new Registered Security in exchange for or in lieu of such other Registered Security as provided in this Article Three,

(e) a new Registered Security which does not bear a Securities Act legend may be issued in exchange for or in lieu of a Registered Security or any portion thereof which bears such a legend if, in the Company's judgment, placing such a legend upon such new Security is not necessary to ensure compliance with the registration requirements of the Securities Act, and the Trustee, at the direction of the Company, shall authenticate and deliver such a new Security as provided in this Article Three, and

(f) notwithstanding the foregoing provisions of this Section 3.05(3), a Successor Security of a Security that does not bear a particular form of Securities Act legend shall not bear such form of legend unless the Company has reasonable cause to believe that such Successor Security is a "restricted security" within the meaning of Rule 144 under the Securities Act, in which case the Trustee, at the direction of the Company, shall authenticate and deliver a new Security bearing a Restricted Securities Legend in exchange for such Successor Security as provided in this Article Three.

36

Section 3.06 Mutilated, Destroyed, Lost and Stolen Securities.

If any mutilated Security is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series and of like tenor and principal amount bearing a number not contemporaneously outstanding, appertaining to the surrendered Security.

If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a protected purchaser, the Company shall execute and the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of the same series and of like tenor and principal amount bearing a number not contemporaneously outstanding.

Notwithstanding the provisions of the previous two paragraphs, in case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security.

Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee connected therewith).

Every new Security of any series issued pursuant to this
Section in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and any such new Security shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of that series duly issued hereunder.

The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities.

Section 3.07 Payment of Interest; Interest Rights Preserved.

Except as otherwise provided as contemplated by Section 3.01 with respect to any series of Securities, interest on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid, in the case of definitive Registered Securities, to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest and, at the option of the Company, may be paid by check mailed to the address of the Person as it appears in the Security Register or, in the case of Global Securities, by wire transfer of same-day funds to the Holder.

Any interest on any Registered Security of any series which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called "Defaulted Interest") shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in Clause (1) or (2) below:

(10) any other Events of Default established as contemplated by
Section 3.01 with respect to Securities of that series.

Section 5.02 Acceleration of Maturity; Rescission and Annulment.

If an Event of Default (other than an Event of Default specified in Section 5.01(4), 5.01(5), 5.01(6) or 5.01(7)) with respect to Securities of any series at the time Outstanding occurs and is continuing, then in every such case the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Securities of such series may declare the principal amount (or, if any of the Securities of that series are Original Issue Discount Securities, such portion of the principal amount of such Securities as may be specified in the terms thereof) of all of the Securities of such series to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any such declaration such principal amount (or specified amount) shall become immediately due and payable. If an Event of Default specified in Section 5.01(4), 5.01(5), 5.01(6) or 5.01(7) with respect to Securities of any series at the time Outstanding occurs, the principal amount of all the Securities of that series (or, if any Securities of that series are Original Issue Discount Securities, such portion of the principal amount of such Securities as may be specified by the terms thereof) shall automatically and without any declaration or other action on the part of the Trustee or any Holder, become immediately due and payable.

At any time after such a declaration of acceleration with respect to Securities of any series has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of the Outstanding Securities of that series, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if:

(1) the Company has paid or deposited with the Trustee a sum sufficient to pay:

(a) all overdue interest on all Securities of that series,

(b) the principal of (and premium and Additional Amounts, if any, on) any Securities of that series which have become due otherwise than by such declaration of acceleration and any interest thereon at the rate or rates prescribed therefor in such Securities,

45

(c) to the extent that payment of such interest is lawful, interest upon overdue interest at the rate or rates prescribed therefor in such Securities, and

(d) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and all other amounts due to the Trustee under Section 6.07;

and

(2) all Events of Default with respect to Securities of that series, other than the non-payment of the principal of Securities of that series which has become due solely by such declaration of acceleration, have been cured or waived as provided in Section 5.13.

No such rescission shall affect any subsequent default or impair any right consequent thereon.

Section 5.03 Collection of Indebtedness and Suits for Enforcement by Trustee.

The Company covenants that if:

(1) default is made in the payment of any interest or payment of any additional interest or Additional Amounts on any Security when such interest becomes due and payable and such default continues for a period of 30 days, or

(2) default is made in the payment of the principal of (or premium, if any, on) any Security at the Maturity thereof and such default continues for a period of 14 days,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities, the whole amount then due and payable, including Additional Amounts, on such Securities for principal and any premium and interest and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal and premium and on any overdue interest, at the rate or rates prescribed therefor in such Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and all amounts due the Trustee under Section 6.07.

If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities of such series by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.

Section 5.04 Trustee May File Proofs of Claim.

In case of any judicial proceeding relative to the Company or any other obligor upon the Securities of a series or the property of the Company or of such other obligor or their creditors, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders of that series of Securities and the Trustee allowed in any such proceeding. In particular, the Trustee shall be authorized to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder of that series of Securities to

46

make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders of that series of Securities, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due to the Trustee under Section 6.07.

No provision of this Indenture shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder of a Security any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder of a Security in any such proceeding provided, however, that the Trustee may, on behalf of the Holders of Securities, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors' or other similar committee.

All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due to the Trustee under Section 6.07, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered.

Section 5.06 Application of Money Collected.

Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal or any premium or interest, upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

FIRST: To the payment of all amounts due the Trustee under
Section 6.07;

SECOND: To the payment of the amounts then due and unpaid for principal of and any premium and interest and any Additional Amounts on the Securities in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal and any premium and interest, respectively; and

48

Section 5.11 Delay or Omission Not Waiver.

No delay or omission of the Trustee or of any Holder of any Security to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein.

(3) in the conversion or exchange of any Security of such series of such Company and the delivery of Securities upon conversion.

Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon.

Prior to 3:00 p.m., New York City time, on the Business Day preceding any payment date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 10.03) an amount of money sufficient to pay such principal, premium, interest and Additional Amounts, if any, payable on such payment date.

Section 10.02 Maintenance of Office or Agency.

The Company may also from time to time designate one or more other offices or agencies where the Securities of one or more series may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in accordance with the requirements set forth above for Securities of any series for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency upon receiving notice of any such change.

The Company will cause each Paying Agent for any series of Securities other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will (i) comply with the provisions of the Trust Indenture Act applicable to it as a Paying Agent and
(ii) during the continuance of any default by the Company (or any other obligor upon the Securities of that series) in the making of any payment in respect of the Securities of that series, and upon the written request of the Trustee, forthwith pay to the Trustee all sums held in trust by such Paying Agent for payment in respect of the Securities of that series.

The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums are held by the Company or such Paying Agent and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money.

65

Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease.

Section 10.04 Additional Amounts.

Unless otherwise specified in any Board Resolution of the Company or indenture supplemental hereto establishing the terms of Securities of a series in accordance with Section 3.01, if any deduction or withholding for any present or future taxes, assessments or other governmental charges of Brazil (or any political subdivision or taxing authority thereof or therein) shall at any time be required by Brazil (or any such political subdivision or taxing authority) in respect of any amounts to be paid by the Company of principal of or interest on a Security of any series, the Company will pay to the Holder of a Security of such series such additional amounts as may be necessary in order that the net amounts paid to such Holder of such Security who, with respect to any such tax, assessment or other governmental charge, is not resident in Brazil, after such deduction or withholding, shall be not less than the amounts specified in such Security to which such Holder is entitled ("Additional Amounts"); provided, however, that the Company shall not be required to make any payment of Additional Amounts for or on account of:

(1) any tax, assessment or other governmental charge which would not have been imposed but for (i) the existence of any present or former connection between such Holder or the beneficial owner of the Security of such series (or between a fiduciary, settler, beneficiary, member or shareholder of, or possessor of a power over, such Holder or beneficial owner, if such Holder or beneficial owner is an estate, trust, partnership or corporation) and Brazil or any political subdivision or territory or possession thereof or area subject to its jurisdiction other than the mere holding of a Security or receipt of payment in respect thereto, including, without limitation, such Holder or beneficial owner (or such fiduciary, settler, beneficiary, member, shareholder or possessor) being or having been a citizen or resident thereof or being or having been present or engaged in trade or business therein or having or having had a permanent establishment therein or
(ii) the presentation of a Security of such series (where presentation is required) for payment on a date more than 30 days after the date on which such payment became due and payable or the date on which payment thereof is duly provided for, whichever occurs later;

(2) any estate, inheritance, gift, sale, transfer, personal property or similar tax, assessment or other governmental charge;

(3) any amount required to be deducted or withheld by any Paying Agent from a payment on or in respect of the Security, if such payment can be made without such deduction or withholding by any other Paying Agent and we duly provide for such other Paying Agent to make such payment;

(4) withholding for any taxes, duties, assessments or other governmental charges that are payable otherwise than by deduction or withholding from payments on the Security;

(5) any tax, assessment or other governmental charge that is imposed or withheld by reason of the failure to comply by the Holder or the beneficial owner of the Security of such series with a request of the Company addressed to the Holder (i) to provide information concerning the nationality, residence or identity of the Holder or such beneficial owner or (ii) to make any declaration or other similar claim or satisfy any information or reporting requirements, which, in the case of (i) or (ii), is required or imposed by a statute, treaty, regulation or administrative practice of Brazil as a precondition to exemption from all or part of such tax, assessment or other governmental charge;

(7) any combination of items (1), (2), (3), (4), (5) and (6) above;

nor shall Additional Amounts be paid with respect to any payment the principal of, or any interest on, any Security of such series to any Holder or beneficial owner who is a fiduciary or partnership or other than the sole beneficial owner of such payment to the extent such payment would be required by the laws of Brazil (or any political subdivision or taxing authority thereof or therein) to be included in the income for tax purposes of a beneficiary or settlor with respect to such fiduciary or a member of such partnership or a beneficial owner who would not have been entitled to such Additional Amounts had it been the Holder or beneficial owner, as the case may be, of such Security. Subject to the foregoing provisions, whenever in this Indenture there is mentioned, in any context, the payment of the principal of or any premium or interest on, or in respect of, any Security of any series or the net proceeds received on the sale or exchange of any Security of any series, such mention shall be deemed to include mention of the payment of Additional Amounts provided for in this
Section to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof pursuant to the provisions of this Section and express mention of the payment of Additional Amounts (if applicable) in any provisions hereof shall not be construed as excluding Additional Amounts in those provisions hereof where such express mention is not made.

If the terms of the Securities of a series established as contemplated by Section 3.01 do not specify that Additional Amounts pursuant to the Section will not be payable by the Company, at least ten days prior to the first Interest Payment Date with respect to that series of Securities (or if the Securities of that series will not bear interest on or prior to Maturity, the first day on which a payment of principal and any premium is made), and at least ten days prior to each date of payment of principal and any premium or interest if there has been any change with respect to the matters set forth in the below-mentioned Officer's Certificate, the Company will furnish the Trustee and the Company's principal Paying Agent or Paying Agents, if other than the Trustee, with an Officer's Certificate instructing the Trustee and such Paying Agent or Paying Agents whether such payment of principal of and any premium or interest on the Securities of that series shall be made to Holders of Securities of that series without withholding for or on account of any tax, assessment or other governmental charge described in the Securities of that series. If any such withholding shall be required, then such Officer's Certificate shall specify the amount, if any, required to be withheld on such payments to such Holders of Securities and the Company will pay to the Trustee or such Paying Agent or Paying Agents the Additional Amounts required by this Section. The Company covenants to indemnify each of the Trustee and any Paying Agent for, and to hold each of them harmless against, any reasonable loss, liability or expense arising out of or in connection with actions taken or omitted by any of them in reliance on any Officer's Certificate furnished pursuant to this Section, except to the extent that any such loss, liability or expense is due to its own negligence or bad faith.

Section 10.05 Statement by Officers as to Default and Notices of Events of Default.

The Company (and each other obligor on the Securities of any series) will deliver to the Trustee, within 90 days after the end of each fiscal year of the Company ending after the date hereof (which, unless the Trustee is notified otherwise, shall be December 31), an Officer's Certificate, stating

67

whether or not to the best knowledge of the signers thereof the Company is in default in the performance and observance of any of the terms, provisions and conditions of this Indenture (without regard to any period of grace or requirement of notice provided hereunder) and, if the Company (or any such obligor) shall be in default, specifying all such defaults and the nature and status thereof of which they may have knowledge. Within 15 days (or promptly with respect to Events of Default pursuant to Sections 5.01(5), 5.01(6) and 5.01(7) hereunder) after the Company becomes aware or should reasonably become aware of the occurrence of an Event of Default pursuant to Section 5.01 hereunder, the Company shall provide notice to the Trustee of such occurrence, accompanied by an Officer's Certificate of the Company setting forth the details thereof.

Section 10.06 Existence.

Subject to Article Eight, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its existence, rights (by-laws (estatuto social) and statutory) and franchises; provided, however, that the Company shall not be required to preserve any such right or franchise if its Board of Directors shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company, and that the loss thereof is not disadvantageous in any material respect to the Holders.

Section 10.07 Waiver of Certain Covenants.

Except as otherwise specified as contemplated by Section 3.01 for Securities of such series, the Company may, with respect to the Securities of any series, omit in any particular instance to comply with any term, provision or condition set forth in any covenant provided pursuant to Section 3.01(23), 9.01(2) or 9.01(6) for the benefit of the Holders of Securities of such series or any term, provision or condition set forth in an indenture supplemental hereto, if before the time for such compliance the Holders of at least a majority in principal amount of the Outstanding Securities of such series shall, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect.

If less than all of the Securities of such series and of a specified tenor are to be redeemed (unless such redemption affects only a single Security), the particular Securities to be redeemed shall be selected less than 30 days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series and specified tenor not previously called for redemption in accordance with the preceding sentence, and the Trustee shall promptly notify the Company in writing of the Securities selected for redemption and, in the case of any Securities selected for partial redemption, the principal amounts thereof to be redeemed.

If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal and any premium shall, until paid, bear interest from the Redemption Date at the rate prescribed therefor in the Security.

Section 11.07 Securities Redeemed in Part.

Any Security which is to be redeemed only in part shall be surrendered at a Place of Payment therefor (with, only in the case of Registered Securities, if the Company or the Trustee so

MEETINGS OF HOLDERS OF SECURITIES

Section 13.01 Purposes for Which Meetings May Be Called.

A meeting of Holders of Securities of a series may be called at any time and from time to time pursuant to this Article to make, give or take any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be made, given or taken by Holders of Securities of such series.

Section 13.02 Call, Notice and Place of Meetings.

(1) The Trustee may at any time call a meeting of Holders of Securities of any series for any purpose specified in Section 13.01, to be held at such time and at such place in the Borough of Manhattan, The City of New York as the Trustee shall determine. Notice of every meeting of Holders of Securities of any series, setting forth the time and the place of such meeting and in general terms the action proposed to be taken at such meeting, shall be given, in the manner provided in Section 1.06, not less than 21 nor more than 180 days prior to the date fixed for the meeting.

(2) In case at any time the Company, pursuant to a Board Resolution, or the Holders of at least 10% in principal amount of the Outstanding Securities of any series shall have requested the Trustee to call a meeting of the Holders of Securities of such series for any purpose specified in
Section 13.01, by written request setting forth in reasonable detail the action proposed to be taken at the meeting, and the Trustee shall not have made the first publication of the notice of such meeting within 21 days after receipt of such request or shall not thereafter proceed to cause the meeting to be held as provided herein, then the Company or the Holders of Securities of such series in the amount specified above, as the case may be, may determine the time and the place in the Borough of Manhattan, The City of New York

72

for such meeting and may call such meeting for such purposes by giving notice thereof as provided in subsection (1) of this Section.

Section 13.03 Persons Entitled to Vote at Meetings.

To be entitled to vote at any meeting of Holders of Securities of any series, a Person shall be (i) a Holder on a record date established pursuant to Section 1.04(3) of one or more Outstanding Securities of such series, or (ii) a Person appointed by an instrument in writing as proxy for a Holder or Holders of one or more Outstanding Securities of such series by such Holder or Holders. The only Persons who shall be entitled to be present or to speak at any meeting of Holders of Securities of any series shall be the Persons entitled to vote at such meeting and their counsel, any representatives of the Trustee and its counsel and any representatives of the Company and its counsel.

Section 13.04 Quorum; Action.

The Persons entitled to vote a majority in principal amount of the Outstanding Securities of a series shall constitute a quorum for a meeting of Holders of Securities of such series. In the absence of a quorum within 15 minutes (or such longer period not exceeding 30 minutes as the chairman may decide) of the time appointed for any such meeting, the meeting shall if convened upon the requisition of Holders be dissolved. In any other case it shall stand adjourned to the same day in the next week (or if such day is not a business day the next succeeding business day) at the same time and place. If within 15 minutes (or such longer period not exceeding 30 minutes as the chairman may decide) after the time appointed for any adjourned meeting a quorum is not present for the transaction of any particular business, then, subject and without prejudice to the transaction of the business (if any) for which a quorum is present, the chairman may either (with the approval of the Trustee) dissolve such meeting or adjourn the same for such period, being not less than ten calendar days (but without any maximum number of calendar days), and to such place as may be appointed by the chairman either at or subsequent to such adjourned meeting and approved by the Trustee, and the provisions of this sentence shall apply to all further adjourned such meetings.

Notice of the reconvening of any adjourned meeting shall be given as provided in Section 13.02(1), except that such notice need be given only once not less than five days prior to the date on which the meeting is scheduled to be reconvened. Notice of a reconvening of an adjourned meeting shall state expressly the percentage, as provided above, of the principal amount of the Outstanding Securities of such series which shall constitute a quorum.

Any resolution passed or decision taken at any meeting of Holders of Securities of any series duly held in accordance with this Section shall be binding on all the Holders of Securities of such series, whether or not presented or represented at the meeting. However, for the avoidance of doubt, no actions taken at such meeting shall be binding on all Holders of Securities unless such actions were approved by the minimum percentage in principal amount of the Outstanding Securities of the series as required elsewhere in this Indenture or under the Trust Indenture Act with respect to such actions.

Section 13.05 Determination of Voting Rights; Conduct and Adjournment of Meetings.

(1) Notwithstanding any other provisions of this Indenture, the Trustee may make such reasonable regulations as it may deem advisable for any meeting of Holders of Securities of a series in regard to proof of the holding of Securities of such series and the appointment of proxies and in regard to the appointment and duties of inspectors of votes, the submission and examination of proxies, certificates and other evidence of the right to vote, and such other matters concerning the conduct of the meeting as it shall deem appropriate. Except as otherwise permitted or required by any such regulations,

73

the holding of Securities shall be proved in the manner specified in Section 1.04 and the appointment of any proxy shall be proved in the manner specified in Section 1.04. Such regulations may provide that written instruments appointing proxies, regular on their face, may be presumed valid and genuine without the proof specified in Section 1.04 or other proof.

(2) The Trustee shall, by an instrument in writing, appoint a temporary chairman of the meeting, unless the meeting shall have been called by the Company or by Holders of Securities as provided in Section 13.02(2), in which case the Company or the Holders of Securities of the series calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the meeting shall be elected by vote of the Persons entitled to vote a majority in principal amount of the Outstanding Securities of such series represented at the meeting.

(3) At any meeting each Holder of a Security of such series or proxy shall be entitled to one vote for each $1,000 principal amount of the Outstanding Securities of such series held or represented by him; provided, however, that no vote shall be cast or counted at any meeting in respect of any Security challenged as not Outstanding and ruled by the chairman of the meeting to be not Outstanding. The chairman of the meeting shall have no right to vote, except as a Holder of a Security of such series or proxy.

(4) Any meeting of Holders of Securities of any series duly called pursuant to Section 13.02 at which a quorum is present may be adjourned from time to time by Persons entitled to vote a majority in principal amount of the Outstanding Securities of such series represented at the meeting, and the meeting may be held as so adjourned without further notice.

Section 13.06 Counting Votes and Recording Action of Meetings.

The vote upon any resolution submitted to any meeting of Holders of Securities of any series shall be by written ballots on which shall be subscribed the signatures of the Holders of Securities of such series or of their representatives by proxy and the principal amounts and serial numbers of the Outstanding Securities of such series held or represented by them. The permanent chairman of the meeting shall appoint two inspectors of votes who shall count all votes cast at the meeting for or against any resolution and who shall make and file with the secretary of the meeting their verified written reports in duplicate of all votes cast at the meeting. A record, at least in duplicate, of the proceedings of each meeting of Holders of Securities of any series shall be prepared by the secretary of the meeting and there shall be attached to said record the original reports of the inspectors of votes on any vote by ballot taken thereat and affidavits by one or more persons having knowledge of the facts setting forth a copy of the notice of the meeting and showing that said notice was given as provided in Section 13.02 and, if applicable, Section 13.04. Each copy shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one such copy shall be delivered to the Company, and another to the Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting.

ARTICLE FOURTEEN

DEFEASANCE AND COVENANT DEFEASANCE

Section 14.01 Company's Option to Effect Defeasance or Covenant Defeasance.

The Company may elect, at its option at any time, to have Section 14.02 or Section 14.03 applied to any Securities or any series of Securities designated pursuant to Section 3.01 as being defeasible pursuant to such Section 14.02 or 14.03, in accordance with any applicable requirements

74

provided pursuant to Section 3.01 and upon compliance with the conditions set forth below in this Article. Any such election shall be evidenced by a Board Resolution or in another manner specified as contemplated by Section 3.01 for such Securities.

Section 14.02 Defeasance and Discharge.

Upon the Company's exercise of its option to have this Section applied to any Securities or any series of Securities, as the case may be, the Company shall be deemed to have been discharged from its obligations with respect to such Securities or series of Securities as provided in this Section on and after the date the conditions set forth in Section 14.04 are satisfied (hereinafter called "Defeasance"). For this purpose, such Defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by such Securities and to have satisfied all its other obligations under such Securities and this Indenture insofar as such Securities are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), subject to the following which shall survive until otherwise terminated or discharged hereunder: (i) the rights of Holders of such Securities to receive, solely from the trust fund described in
Section 14.04 and as more fully set forth in such Section, payments in respect of the principal of and any premium and interest on such Securities when payments are due, (ii) the Company's obligations with respect to such Securities under Sections 3.04, 3.05, 3.06, 10.02 and 10.03, (iii) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (iv) this Article Fourteen. Subject to compliance with this Article, the Company may exercise its option to have this Section 14.02 applied to any Securities notwithstanding the prior exercise of its option to have Section 14.03 applied to such Securities.

Section 14.03 Covenant Defeasance.

Upon the Company's exercise of its option to have this Section applied to any Securities or any series of Securities, as the case maybe, (i) the Company shall be released from any covenants provided pursuant to Section 3.01(23), 9.01(2) or 9.0l(7) for the benefit of the Holders of such Securities, and (ii) the occurrence of any event specified in Sections 5.01(3) and 5.01(8) shall be deemed not to be or result in an Event of Default, in each case with respect to such Securities as provided in this Section on and after the date the conditions set forth in Section 14.04 are satisfied (hereinafter called "Covenant Defeasance"). For this purpose, such Covenant Defeasance means that, with respect to such Securities, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such specified Section (to the extent so specified in the case of Section 5.01(3)), whether directly or indirectly by reason of any reference elsewhere herein to any such Section or by reason of any reference in any such Section to any other provision herein or in any other document, but the remainder of this Indenture and such Securities shall be unaffected thereby.

Section 14.04 Conditions to Defeasance or Covenant Defeasance.

The following shall be the conditions to the application of
Section 14.02 or Section 14.03 to any Securities or any series of Securities, as the case may be:

75

discharge, and which shall be applied by the Trustee to pay and discharge, the principal of and any premium, interest and Additional Amounts on such Securities on the respective Stated Maturities, in accordance with the terms of this Indenture and such Securities. As used herein, "U.S. Government Obligation" means (x) any security which is (A) a direct obligation of the United States of America for the payment of which the full faith and credit of the United States of America is pledged or (B) an obligation of a Person controlled or supervised by and acting as any agency or instrumentality of the United States of America the payment of which is unconditionally guaranteed as a full faith and credit obligation by the United States of America, which, in either case (A) or (B), is not callable or redeemable at the option of the issuer thereof, and (y) any depositary receipt issued by a bank (as defined in Section 3(a)(2) of the Securities Act) as custodian with respect to any U.S. Government Obligation which is specified in Clause (x) above and held by such bank for the account of the holder of such depositary receipt, or with respect to any specific payment of principal of or interest on any U.S. Government Obligation which is so specified and held, provided that (except as required by law) such custodian is not authorized to make any deduction from the amount payable to the holder of such depositary receipt from any amount received by the custodian in respect of the U.S. Government Obligation or the specific payment of principle or interest evidenced by such depositary receipt.

(2) In the event of any election to have Section 14.02 apply to any Securities or any series of Securities, as the case may be, the Company shall have delivered to the Trustee an Opinion of Counsel stating that (i) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (ii) since the date of this instrument, there has been a change in the applicable U.S. Federal income tax law, in either case (i) or (ii) to the effect that, and based thereon such opinion shall confirm that, the Holders of such Securities will not recognize gain or loss for U.S. Federal income tax purposes as a result of the deposit, Defeasance and discharge to be effected with respect to such Securities and will be subject to Federal income tax on the same amount, in the same manner and at the same times as would be the case if such deposit, Defeasance and discharge were not to occur.

(3) In the event of an election to have Section 14.03 apply to any Securities or any series of Securities, as the case may be, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of such Securities will not recognize gain or loss for Federal income tax purposes as a result of the deposit and Covenant Defeasance to the effected with respect to such Security and will be subject to Federal income tax on the same amount, in the same manner and at the same times as would be the case if such deposit and Covenant Defeasance were not to occur.

(4) The Company shall have delivered to the Trustee an Opinion of Counsel to the effect that neither such Securities nor any other Securities of the same series, if then listed on any securities exchange, will be delisted as a result of such deposit.

(5) No event which is, or after notice or lapse of time both would become, an Event of Default with respect to such Securities or any other Securities shall have occurred and be continuing at the time of such deposit or, with regard to any such event specified in Sections 5.01(4), 5.01(5), 5.01(6) and 5.01(7), at any time on or prior to the day which is 90 days after the date of such deposit (it being understood that this condition shall not be deemed satisfied until after such day which is 90 days after the date of such deposit).

(6) Such Defeasance or Covenant Defeasance shall not cause the Trustee to have a conflicting interest within the meaning of the Trust Indenture Act (assuming all Securities are in default within the meaning of such Act).

76

(7) Such Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, any other agreement or instrument to which the Company is a party or by which it is bound.

(8) Such Defeasance or Covenant Defeasance shall not result in the trust arising from such deposit constituting an investment company within the meaning of the Investment Company Act unless such trust shall be registered under such Act or exempt from registration thereunder.

(9) The Company shall have delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that all conditions precedent with respect to such Defeasance or Covenant Defeasance have been complied with.

Section 14.05 Deposited Money and U.S. Government Obligations to Be Held in Trust; Miscellaneous Provisions.

Subject to the provisions of the last paragraph of Section 10.03, all money and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee pursuant to Section 14.04 in respect of any Securities shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and this Indenture, to the payment, either directly or through any such Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Holders of such Securities, of all sums due and to become due thereon in respect of principal and any premium and interest, but money so held in trust need not be segregated from other funds except to the extent required by law.

The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the U.S. Government Obligations deposited pursuant to Section 14.04, or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of Outstanding Securities.

Anything in this Article to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon Order any money or U.S. Government Obligations held by it as provided in Section 14.04 with respect to any Securities which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect the Defeasance or Covenant Defeasance, as the case may be, with respect to such Securities.

Section 14.06 Reinstatement.

If the Trustee or the Paying Agent is unable to apply any money in accordance with this Article with respect to any Securities by reason of any order of judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the obligations under this Indenture and such Securities from which the Company has been discharged or released pursuant to Section 14.02 or 14.03 shall be revived and reinstated as though no deposit had occurred pursuant to this Article with respect to such Securities in accordance with this Article; provided, however, that if the Company makes any payment of principal of or any premium or interest on any such Security following such reinstatement of its obligations, the Company shall be subrogated to the rights (if any) of the Holders of such Securities to receive such payment from the money so held in trust.

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

77

IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be duly executed on their respective behalves, all as of the day and year first above written.

Nothing in this paragraph shall be construed to prevent the Company from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be canceled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders, or their duly designated proxies, of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken.

Nothing in this paragraph shall be construed to prevent the Trustee from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be canceled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders, or their duly designated proxies, of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Trustee, at the expense of the Company, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Company in writing and to each Holder of Securities of the relevant series in the manner set forth in Section 1.06.

With respect to any record date set pursuant to this Section, the party hereto which sets such record date may designate any day as the "Expiration Date" and from time to time may change the Expiration Date to any earlier or later day; provided that no such change shall be effective unless notice of the proposed new Expiration Date is given to the other party or parties hereto in writing, and to each Holder of Securities of the relevant series in the manner set forth in Section 1.06, on or prior to the existing Expiration Date. Notwithstanding the foregoing, no Expiration Date shall be later than the 180th day after the applicable record date and, if an Expiration Date is not designated with respect to any record date set pursuant to this Section, the party or parties hereto which set such record date shall be deemed to have designated the 180th day after such record date as the Expiration Date with respect thereto.

In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice to Holders of Securities by mail, then such notification as shall be given with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder. In any case where notice to Holders of Securities is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder of a Security shall affect the sufficiency of such notice with respect to other Holders of Securities.

Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall

15

be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

In case of the failure of Petrobras International Finance Company, a Cayman Islands limited company (herein called the "Borrower," which term includes any successor Person under such Indenture), to punctually make any such payment of principal of, premium, if any, and interest (including additional amounts, if any) on or any such sinking fund or analogous payment, the Guarantor hereby agrees to cause such payment to be made punctually when and as the same shall become due and payable, whether on the Stated Maturity or by declaration of acceleration, call for redemption or otherwise, and as if such payment were made by the Borrower.

The Guarantor hereby agrees that its obligations hereunder shall be as if it were the principal debtor and not merely surety, and shall be absolute and unconditional, irrespective of, and shall be unaffected by, any invalidity, irregularity or unenforceability of such Security or such Indenture, and failure to enforce the provisions of such Security or such Indenture, or any waiver, modification or indulgence granted to the Borrower with respect thereto, by the Holder of such Security or the Trustee or any other circumstance which may otherwise constitute a legal or equitable discharge of a surety or guarantor; provided, however, that, notwithstanding the foregoing, no such waiver, modification or indulgence shall, without the consent of the Guarantor, increase the principal amount of such Security, or increase the interest rate thereon, or increase any premium or additional amounts payable thereon, or alter the Stated Maturity thereof, or increase the principal amount of any Original Issue Discount Security that would be due and payable upon a declaration of acceleration of the maturity thereof pursuant to Article V of such Indenture. The Guarantor hereby waives diligence, presentment, demand for payment, filing of claims with a court in the event of merger or bankruptcy of the Borrower, any right to require a proceeding first against the Borrower, protest or notice with respect to such Security or the indebtedness evidenced thereby or with respect to any sinking fund or analogous payment required under such Security and all demands whatsoever, and covenants that this Guarantee will not be discharged except by payment in full of the principal of, premium, if any, and interest (including additional amounts, if any) on such Security.

The Guarantor shall be subrogated to all rights of the Holder of such Security and the Trustee against the Borrower in respect of any amounts paid to such Holder by the Guarantor pursuant to the provisions of this Guarantee; provided, however, that the Guarantor shall not be entitled to enforce, or to receive any payments arising out of or based upon such right of subrogation until the principal of, premium, if any, and interest (including additional amounts, if any) on all Securities of the same series issued under such Indenture shall have been paid in full.

No reference herein to such Indenture and no provision of the Guarantee or of such Indenture shall alter or impair the guarantees of the Guarantor, which are absolute and unconditional, of the due and punctual payment of the principal of, premium, if any, and interest (including additional amounts, if any) on, and any sinking fund or analogous payments with respect to, the Security upon which this Guarantee is endorsed.

This Guarantee shall not be valid or obligatory for any purpose until the certificate of authentication of such Security shall have been manually executed by or on behalf of the Trustee under such Indenture.

All terms used but not defined in this Guarantee which are defined in such Indenture shall have the meanings assigned to them in such Indenture.

The Securities shall be executed on behalf of the Company by any Authorized Representative of the Company. The signature of any such Authorized Representative of the Company may be manual or facsimile.

Securities bearing the manual or facsimile signatures of individuals who were at any time a proper Authorized Representative of the Company shall bind the Company notwithstanding that such individuals or any of them have ceased to hold such positions prior to the authentication and delivery of such Securities or did not hold such positions at the date of such Securities.

At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series, executed by the Company to the Trustee for authentication, together with an Order for the authentication and delivery of such Securities, and the Trustee in accordance with the Order shall authenticate and deliver such Securities.

If the forms or terms of the Securities of the series have been established in or pursuant to one or more Authorizations as permitted by Sections 2.01 and 3.01, in authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive, and (subject to Section 6.01) shall be fully protected in relying upon, an Opinion of Counsel and Officers' Certificate stating,

(1) that such forms or terms have been established in conformity with the provisions of this Indenture; and

(2) that such Securities, when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company enforceable in accordance with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors' rights and to general equity principles.

36

The Trustee shall have the right to decline to authenticate and deliver any Securities under this Section if the Trustee, being advised in writing by counsel, determines that such action may not lawfully be taken or if the Trustee in good faith shall determine that such action would expose the Trustee to personal liability based upon the written advice of counsel.

The Trustee shall not be required to authenticate the Securities of any series if the issue of such Securities pursuant to this Indenture will affect the Trustee's own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee.

Notwithstanding the provisions of Section 3.01 and of the preceding paragraph, if all Securities of a series are not to be originally issued at one time, it shall not be necessary to deliver the Officer's Certificate otherwise required pursuant to Section 3.01 or the Order and Opinion of Counsel otherwise required pursuant to such preceding paragraph at or prior to the time of authentication of each Security of such series if such documents are delivered at or prior to the authentication upon original issuance of the first Security of such series to be issued.

Each Security shall be dated the date of its authentication.

No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Security to the Trustee for cancellation as provided in Section 3.09, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture.

Section 3.04 Temporary Securities.

Pending the preparation of definitive Securities of any series, the Company may execute, and upon Order the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued, in registered form and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of such Securities. A Temporary Regulation S Security shall be delivered only in compliance with the conditions set forth in Section 3.03 and this Section 3.04.

If temporary Securities of any series are issued, the Company will cause definitive Securities of that series to be prepared without unreasonable delay. After the preparation of definitive Securities of such series, the temporary Securities of such series shall be exchangeable for definitive Securities of such series upon surrender of the temporary Securities of such series at the office or agency of the Company in a Place of Payment for that series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any series, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor one or more definitive Securities of the same series, of any authorized denominations and of a like aggregate principal amount and tenor.

37

If Temporary Regulation S Securities of any series are issued, any such Temporary Regulation S Security shall, unless otherwise provided therein, be delivered to DTC or its nominee or the Common Depositary, in each case, for the benefit of the Euroclear Operator and Clearstream, Luxembourg, for credit to the respective accounts of the beneficial owners of such Securities (or to such other accounts as they may direct).

Without unnecessary delay but in any event not later than the date specified in, or determined pursuant to the terms of, any such Temporary Regulation S Security of a series (the "Exchange Date"), the Company shall deliver to the Trustee definitive Securities of that series in aggregate principal amount equal to the principal amount of such Temporary Regulation S Security executed by the Company. On or after the Exchange Date, such Temporary Regulation S Security shall be surrendered by DTC or its nominee or the Common Depositary, as the case may be, to the Trustee, as the Company's agent for such purpose, to be exchanged, in whole or from time to time in part, for definitive Securities of that series without charge, and the Trustee shall authenticate and deliver, in exchange for each portion of such Temporary Regulation S Security a like aggregate principal amount of definitive Securities of the same series of authorized denominations and of like tenor as the portion of such Temporary Regulation S Security to be exchanged; provided however, that upon such presentation by DTC or its nominee or the Common Depositary, such Temporary Regulation S Security must be accompanied by a certificate dated the Exchange Date or a subsequent date and signed by the Euroclear Operator as to the portion of such Temporary Regulation S Security held for its account then to be exchanged and a certificate dated the Exchange Date or a subsequent date and signed by Clearstream, Luxembourg as to the portion of such Temporary Regulation S Security held for its account then to be exchanged, each in the form set forth in Section 3.12(2). The definitive Securities to be delivered in exchange for any such Temporary Regulation S Security shall, unless otherwise specified in the Temporary Regulation S Security, be in or in the form of Permanent Regulation S Securities.

Unless otherwise specified in the Temporary Regulation S Security, the interest of a beneficial owner of Securities of a series in a Temporary Regulation S Security shall be exchanged on the Exchange Date for interest in a permanent global registered Security (a "Permanent Regulation S Security") of the same series and of like tenor unless, on or prior to the Exchange Date, such beneficial owner has not delivered to the Euroclear Operator or Clearstream, Luxembourg, as the case may be, a certificate in the form set forth in Section 3.12(1) dated no earlier than the Certification Date, copies of which certificate shall be available from the office of the Euroclear Operator and Clearstream, Luxembourg, the Trustee, and any Authenticating Agent appointed for such series of Securities and each Paying Agent and after the Exchange Date, the interest of a beneficial owner of Securities of a series in a Temporary Regulation S Security shall be exchanged for an interest in a Permanent Regulation S Security of the same series and of like tenor following such beneficial owner's delivery to the Euroclear Operator or Clearstream, Luxembourg, as the case may be, of a certificate in the form set forth in
Section 3.12(1) dated no earlier than the Certification Date. Unless otherwise specified in such Temporary Regulation S Security, any such exchange shall be made free of charge to the beneficial owners of such Temporary Regulation S Security.

Until exchanged in full as hereinabove provided, the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of the same series and of like tenor authenticated and delivered hereunder, except that, interest payable on a Temporary Regulation S Security on an Interest Payment Date for Securities of such series shall be payable to the Euroclear Operator and Clearstream, Luxembourg on such Interest Payment Date only upon delivery by the Euroclear Operator or Clearstream, Luxembourg to the Trustee of a certificate or certificates in the form set forth in Section 3.12(2), for credit without further interest on or after such

38

Interest Payment Date to the respective accounts of the Persons who are the beneficial owners of such Temporary Regulation S Security on such Interest Payment Date and who have each delivered to the Euroclear Operator or Clearstream, Luxembourg, as the case may be, a certificate in the form set forth in Section 3.12(1). Any interest so received by the Euroclear Operator and Clearstream, Luxembourg and not paid as herein provided shall be returned to the Trustee immediately prior to the expiration of two years after such Interest Payment Date in order to be repaid to the Company in accordance with Section 10.17.

Section 3.05 Registration, Registration of Transfer and Exchange.

(1) The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in any other office or agency of the Company in a Place of Payment being herein sometimes collectively referred to as the "Security Register") in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Registered Securities and of transfers of Registered Securities. The Trustee is hereby appointed "Security Registrar" for the purpose of registering Registered Securities and transfers of Registered Securities as herein provided. Such Security Register shall distinguish between Original Securities and Exchange Securities.

Except as otherwise provided in this Section 3.05(1), upon surrender for registration of transfer of a Registered Security of any series at the office or agency in a Place of Payment for that series, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Registered Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount.

Subject to Section 3.05(2), at the option of the Holder, Registered Securities of any series may be exchanged for other Registered Securities of the same series, of any authorized denominations and of a like tenor and aggregate principal amount upon surrender of the Registered Securities to be exchanged at such office or agency. Whenever any Registered Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Registered Securities which the Holder making the exchange is entitled to receive.

All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company evidencing the same debt (subject to the provisions, if any, in the Original Securities regarding payment of Special Interest) and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange.

Every Registered Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed, by the Holder thereof or his attorney duly authorized in writing.

In the event that the Company delivers to the Trustee a copy of an Officer's Certificate certifying that a registration statement under the Securities Act with respect to an Exchange Offer relating to a particular series of Securities, if any such Exchange Offer is contemplated for such series, has been declared effective by the Commission and that the Company has offered Exchange Securities of such series to the Holders in accordance with the Exchange Offer, the Trustee shall exchange, upon request of any Holder, such Holder's Securities for Exchange Securities upon the terms set forth in the Exchange Offer.

39

No service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Sections 3.04, 9.06 or 11.07 not involving any transfer.

The Company shall not be required (i) to issue, register the transfer of or exchange Registered Securities of any series during a period beginning at the opening of business 15 days before any selection of Securities of that series to be redeemed and ending at the close of business on the day of the mailing of the relevant notice of redemption or (ii) to register the transfer of or exchange any Registered Security so selected for redemption, in whole or in part, except the unredeemed portion of any Security being redeemed in part.

The provisions of Clauses (a), (b), (c) and (d) below shall apply only to Global Registered Securities:

(a) Each Global Security authenticated under this Indenture shall be registered in the name of the Depositary designated for such Global Security or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each such Global Security shall constitute a single Security for all purposes of this Indenture.

(b) Subject to Clause (4) below, any exchange of a Global Security for other Securities may be made in whole or in part, and all Securities issued in exchange for a Global Security or any portion thereof shall be registered in such names as the Depositary for such Global Security shall direct.

(c) Every Security authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global Security or any portion thereof, whether pursuant to this Section, Sections 3.04, 3.06, 9.06 or 11.07 or otherwise, shall be authenticated and delivered in the form of, and shall be, a Global Security, unless such Security is registered in the name of a Person other than the Depositary for such Global Security or a nominee thereof.

(d) Except as provided below, owners of beneficial interests in Global Securities will not be entitled to receive Registered Securities in their names ("Certificated Securities"). Certificated Securities shall be issued to all owners of beneficial interests in a Global Note in exchange for such interests if:

(i) The Depositary notifies the Company that it is unwilling or unable to continue as depositary for such Global Note or the Depositary ceases to be a clearing agency registered under the Exchange Act, at a time when such Depositary is required to be so registered in order to act as depositary, and in each case, and a successor depositary is not appointed by the Company within 90 days of such notice,

(ii) The Depositary executes and delivers to the Trustee and the Security Registrar an Officers' Certificate stating that such Global Note shall be so exchangeable, or

(iii) an Event of Default has occurred and is continuing and the Security Registrar has received a request from the Depositary or the Security Registrar and the Company have received a request from the Trustee.

40

In connection with the exchange of an entire Global Security for Certificated Securities pursuant to this Clause (d), such Global Note shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and upon receipt of an Order the Trustee shall authenticate and deliver, to each beneficial owner identified by the Depositary in exchange for its beneficial interest in such Global Security, an equal aggregate principal amount of Certificated Securities of authorized denominations.

(e) Members of, or participants in, DTC or Euroclear and Clearstream, Luxembourg, as the case may be ("Agent Members"), shall have no rights under this Indenture with respect to any Global Security held on their behalf by DTC or by the Common Depositary under such Global Security, and DTC or the Common Depositary, as the case may be, may be treated by the Company, the Trustee, the Paying Agent and the Security Registrar and any of their agents as the absolute owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee, the Paying Agent or the Security Registrar or any of their agents from giving effect to any written certification, proxy or other authorization furnished by DTC or the Common Depositary or impair, as between DTC or Euroclear and Clearstream, Luxembourg and their respective Agent Members, the operation of customary practices governing the exercise of the rights of an owner of a beneficial interest in any Global Security. The registered Holder of a Global Security may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action that a Holder is entitled to take under this Indenture or the Securities.

(2) Certain Transfers and Exchanges.

(a) The following provisions shall apply with respect to any proposed transfer of an interest in a Restricted Global Security: If (i) the owner of a beneficial interest in a Restricted Global Security wishes to transfer such interest (or portion thereof) to a Non-U.S. Person pursuant to Regulation S and (ii) such Non-U.S. Person wishes to hold its interest in the Security through a beneficial interest in the Regulation S Global Security, (x) upon receipt by the Depositary and Security Registrar of:

42

If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a protected purchaser, the Company shall execute and the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of the same series and of like tenor and principal amount bearing a number not contemporaneously outstanding.

Notwithstanding the provisions of the previous two paragraphs, in case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security.

Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee connected therewith.

Every new Security of any series issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and any such new Security shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of that series duly issued hereunder.

The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities.

Any interest on any Registered Security of any series which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called "Defaulted Interest") shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in Clause (1) or (2) below:

The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted interest as in this Clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest, which shall be not more than 15 days and not less than ten days prior to the date of the proposed payment and not less than ten days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be given to each Holder of Securities of such series in the manner set forth in Section 1.06, not less than ten days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following Clause (2).

(2) The Company may make payment of any Defaulted interest on the Securities of any series in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this Clause, such manner of payment shall be deemed practicable by the Trustee.

Subject to the foregoing provisions of this Section and Section 3.05, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such predecessor Security.

The Company shall promptly notify the Trustee of any change in the CUSIP numbers.

If an Event of Default specified in Section 5.01(6), 5.01(7), 5.01(8) or 5.01(9) with respect to Securities of any series at the time Outstanding occurs, the principal amount of all the Securities of that series (or, if any Securities of that series are Original Issue Discount Securities, such portion of the principal amount of such Securities as may be specified by the terms thereof) shall automatically and without any declaration or other action on the part of the Trustee or any Holder, become immediately due and payable.

Anything in this Section 10.17, to the contrary notwithstanding, the agreements to hold sums in trust as provided in this
Section are subject to the provisions of Section 4.02.

The Company agrees to indemnify the Holders against any failure on the part of any Paying Agent to pay, in accordance with the terms hereof, any sum due in respect of any series of Securities on the applicable Payment Date.

76

3.01(23), 9.01(2) or 9.01(6) for the benefit of the Holders of Securities of such series or any term, provision or condition set forth in an indenture supplemental hereto, if before the time for such compliance the Holders of at least a majority in principal amount of the Outstanding Securities of such series shall, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect.

Section 10.19 Additional Amounts.

Unless otherwise specified in any Board Resolution of the Company or indenture supplemental hereto establishing the terms of Securities of a series in accordance with Section 3.01, if any deduction or withholding for any present or future taxes, assessments or other governmental charges of Brazil (or any political subdivision or taxing authority thereof or therein) shall at any time be required by Brazil (or any such political subdivision or taxing authority) in respect of any amounts to be paid by the Company of principal of or interest on a Security of any series, the Company will pay to the Holder of a Security of such series such additional amounts as may be necessary in order that the net amounts paid to such Holder of such Security who, with respect to any such tax, assessment or other governmental charge, is not resident in Brazil, after such deduction or withholding, shall be not less than the amounts specified in such Security to which such Holder is entitled ("Additional Amounts"); provided, however, that the Company shall not be required to make any payment of Additional Amounts for or on account of:

Anything in this Article to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon Order any money or U.S. Government Obligations held by it as provided in Section 14.04 with respect to any Securities which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect the Defeasance or Covenant Defeasance, as the case may be, with respect to such Securities.

Section 14.06 Reinstatement.

If the Trustee or the Paying Agent is unable to apply any money in accordance with this Article with respect to any Securities by reason of any order of judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the obligations under this Indenture and such Securities from which the Company has been discharged or released pursuant to Section 14.02 or 14.03 shall be revived and reinstated as though no deposit had occurred pursuant to this Article with respect to such Securities in accordance with this Article; provided, however, that if the Company makes any payment of principal of or any premium or interest on any such Security following such reinstatement of its obligations, the Company shall be subrogated to the rights (if any) of the Holders of such Securities to receive such payment from the money so held in trust.

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

[SOUZA, CESCON AVEDISSIAN, BARRIEU E FLESCH ADVOGADOS LETTERHEAD]

Sao Paulo, July 18, 2002.

To

Petroleo Brasileiro S.A. - Petrobras
Avenida Republica do Chile, 65
Rio de Janeiro, RJ
Brazil

Ladies and Gentlemen:

We have acted as Brazilian special counsel to Petroleo Brasileiro S.A. - Petrobras ("Petrobras"), a mixed-capital company (sociedade de economia mista) organized under the laws of the Federative Republic of Brazil ("Brazil"), in connection with the preparation and filing by Petrobras and Petrobras International Finance Company, a corporation organized under the laws of the Cayman Islands ("PIFCo"), under the Securities Act of 1933, as amended (the "Securities Act"), of a Registration Statement on Form F-3 (the "Registration Statement") with the United States Securities and Exchange Commission (the "SEC") with respect to (i) unsecured debt securities of Petrobras (the "Petrobras Debt Securities"), (ii) unsecured debt securities of PIFCo (the "PIFCo Debt Securities") accompanied by guarantees (the "Guarantees") or standby purchase agreements (the "Standby Purchase Agreements") of Petrobras,
(iii) preferred shares of Petrobras, including the share purchase rights associated therewith (collectively, the "Preferred Shares"), in one or more series, (iv) common shares of Petrobras, including the share purchase rights associated therewith (collectively, the "Common Shares"), (v) warrants to purchase Petrobras Debt Securities, Preferred Shares or Common Shares (the "Warrants") and (vi) securities mandatorily convertible into Preferred Shares or Common Shares (the "Mandatory Convertible Securities" and, together with the Common Shares, the Preferred Shares, the Petrobras Debt Securities, the PIFCo Debt Securities, the Guarantees, the Standby Purchase Agreements and the Warrants, the "Securities") to be issued from time to time on a delayed and continuous basis pursuant to Rule 415 under the Securities Act, for an aggregate initial offering price not to exceed US$8,000,000,000.

In rendering this opinion, we have reviewed:

(i) the Registration Statement;

(ii) the form of indenture between Petrobras, as issuer, and JP Morgan Chase Bank, as trustee (the "Petrobras Indenture"), pursuant to which Petrobras Debt Securities may be issued;


[SOUZA, CESCON AVEDISSIAN, BARRIEU E FLESCH ADVOGADOS LETTERHEAD] 2

(iii) the form of indenture between PIFCo, as issuer, and JP Morgan Chase Bank, as trustee (the "PIFCo Indenture"), pursuant to which PIFCo Debt Securities may be issued; and

(iv) the by-laws (estatutos sociais) of Petrobras, as in effect on the date hereof.

In addition, we have made such inquiries and examined originals (or copies of certified or otherwise identified to our satisfaction) of such documents and such other instruments and other certificates of public officials, officers and representatives of Petrobras, and we have made such investigations of law, as we have deemed appropriate as a basis for the opinions expressed below. In such examinations, we have assumed, without any independent investigation or verification of any kind, the genuineness of all signatures, the legal capacity at all relevant times of any natural persons signing any documents, the authenticity of all documents submitted to us as originals, the conformity to the original documents of all documents submitted to us as certified, photostatic, electronic or facsimile copies and the truthfulness of all certificates of public officials and corporate officers.

We have also assumed that (i) the Registration Statement, and any amendments thereto (including post-effective amendments), will have become effective; (ii) a prospectus supplement will have been prepared and filed with the SEC describing the Securities offered thereby; (iii) all Securities will be issued and sold in compliance with all applicable laws and in the manner stated in the Registration Statement and the appropriate prospectus supplement; (iv) a definitive purchase, underwriting or similar agreement with respect to any Securities offered will have been duly authorized and validly executed and delivered by Petrobras and/or PIFCo and the other parties thereto; and (v) any Securities issuable upon conversion, exchange or exercise of any other Security being offered will be duly authorized, created and, if appropriate, reserved for issuance upon such conversion, exchange or exercise.

Furthermore, we have assumed (i) the due organization and valid existence of all parties to the Petrobras Indenture (other than Petrobras) and the PIFCo Indenture under the laws of the countries of their respective incorporation; (ii) the due authorization, execution and delivery of the Petrobras Indenture and the PIFCo Indenture by all parties thereto (other than Petrobras); (iii) that the performance thereof is within the capacity and powers of all such parties; and (iv) the validity and enforceability of the Petrobras Indenture, the PIFCo Indenture and the Securities in accordance with their terms under the laws of the State of New York, by which they are expressed to be governed.

We are qualified to practice law solely in Brazil and express no opinion as to any laws other than the laws of Brazil as in effect on the date hereof, and we have assumed that there is nothing in any other law that affects our opinion. In particular, we have made no independent investigation of the laws of the State of New York, or the laws of the Cayman Islands, as a basis for the opinions stated herein, and we do not express or imply any opinion on such laws. The opinions stated below are provided based on Brazilian laws, rules and regulations and on Petrobras' By-laws, in each case as in effect on the date hereof, and we


[SOUZA, CESCON AVEDISSIAN, BARRIEU E FLESCH ADVOGADOS LETTERHEAD] 3

assume that there will be no change in Brazilian laws, rules or regulations (or the interpretation thereof) nor amendments to Petrobras' By-laws that may affect in any way the opinions stated herein.

Based upon the foregoing, and subject to the assumptions and qualifications herein contained, we are of the opinion that:

2. In the event that, in connection with the issuance, offer and sale of the Common Shares, (i) all applicable governmental approvals are obtained and all necessary filings and registrations with any governmental authority, agency or body are effective, (ii) all necessary corporate and shareholder actions are taken by Petrobras and its shareholders, including actions taken by the General Shareholders Meeting, the Board of Directors (Conselho de Administracao), the Board of Executive Officers (Diretoria) and the Fiscal Council (Conselho Fiscal) of Petrobras or a combination of such bodies (iii) a definitive underwriting, purchase or similar agreement relating to the issuance, offer and sale of the Common Shares is duly authorized, executed and delivered by all parties thereto, including Petrobras, and (iv) the Common Shares are sold and delivered to, and fully paid for by, the purchasers at a price specified in, and in accordance with the terms of, such definitive underwriting, purchase or similar agreement, then the Common Shares will be duly authorized, validly issued, fully paid and non-assessable.

(ii) in order to ensure the admission and enforceability of the Petrobras Indenture, the PIFCo Indenture or the Securities, as the case may be, before the public agencies and courts in Brazil (a) (x) the signatures of the parties thereto signing outside Brazil must be notarized by a notary public licensed as such under the laws of the place of signing and the signature of such notary public must be authenticated by a consular official of Brazil or (y) the Petrobras Indenture, the PIFCo Indenture or the Securities, as the case may be, together with its sworn translation into Portuguese language, must be registered with the appropriate Registry of Titles and Deeds in Brazil and (b) the Petrobras Indenture, the PIFCo Indenture or the Securities, as the case may be, must be translated into the Portuguese language by a sworn translator; and

(iii) any judgment obtained against Petrobras in a foreign court with respect to the Petrobras Indenture, the PIFCo Indenture or the Securities, as the case may be, will only be enforceable in the courts of Brazil if previously confirmed (homologado) by the Federal Supreme Court of Brazil. Such confirmation will only occur if such judgment: (a) fulfils all formalities required for its enforceability under the laws of the country wherein it is issued; (b) is issued by a competent court after proper service of process on Petrobras; (c) is not subject to appeal; (d) is authenticated by a Brazilian


[SOUZA, CESCON AVEDISSIAN, BARRIEU E FLESCH ADVOGADOS LETTERHEAD] 6

Consulate in the jurisdiction wherein it is issued and is accompanied by a certified translation into Portuguese language; and (e) is not contrary to Brazilian national sovereignty, public policy or morality (as provided in Article 17 of the Law of Introduction to the Brazilian Civil Code).

We hereby consent to the use of our name in the prospectus constituting a part of the Registration Statement and in any prospectus supplements related thereto under the heading "Legal Matters" as counsel for Petrobras who have passed on the validity of the Securities being registered by the Registration Statement. In giving such consent, we do not thereby admit that we are within the category of persons whose consent is required under Section 7 of the United Securities Act of 1933, as amended, or the rule and regulations of the SEC thereunder.

Yours faithfully,

Dear Sirs:

Registration Statement on Form F-3 under the Securities Act of 1933, as amended, of Petrobras International Finance Company and Petroleo Brasileiro S.A. - Petrobras

We have acted as Cayman Islands special counsel to Petrobras International Finance Company (the "Company"), an exempted company incorporated with limited liability under the laws of the Cayman Islands, in connection with the preparation and filing by Petroleo Brasileiro S.A. - Petrobras ("Petrobras"), a mixed-capital company (sociedade de economia mista) organized under the laws of the Federative Republic of Brazil, and the Company under the Securities Act of 1933, as amended (the "Securities Act") of a Registration Statement on Form F-3 (the "Registration Statement") with the United States Securities and Exchange Commission (the "SEC") with respect to (i) debt securities of the Company ("Company Debt Securities") and (ii) common shares, preferred shares, warrants on common or preferred shares, unsecured company debt securities and mandatorily convertible securities of Petrobras and guarantees and standby purchase agreements of Petrobras relating to Company Debt Securities (such shares, warrants, mandatorily convertible securities, guarantees and standby purchase agreements, collectively, the "Petrobras Securities"). The Company Debt Securities and the Petrobras Securities are to be issued from time to time on a delayed and continuous basis pursuant to Rule 415 under the Securities Act, for an aggregate initial offering price not to exceed $8,000,000,000.

In rendering this opinion, we have reviewed

(a) the Registration Statement;


(b) the form of indenture between the Company, as issuer, and JP Morgan Chase Bank, as trustee (the "Indenture"), pursuant to which Company Debt Securities may be issued; and

(c) the memorandum of association and articles of association of the Company in effect on the date hereof;

and we have made such inquiries and examined originals (or copies certified or otherwise identified to our satisfaction) of such documents, corporate records and other instruments and made such examination of the law as we have deemed necessary or appropriate to enable us to render this opinion. In such examinations, we have assumed the genuineness of all signatures, the legal capacity at all relevant times of any natural persons signing any documents, the authenticity of all documents submitted to us as originals, the conformity to authentic originals of all documents submitted to us as certified or true copies or as reproductions (including documents received by facsimile) and the truthfulness of all certificates of public officials and corporate officers. For the purposes of this opinion the Indenture, any supplemental indenture, any Company Debt Security and any other documents pursuant to which Company Debt Securities are constituted, offered or secured are collectively referred to as "Transaction Documents".

In connection with this opinion, we have relied upon the following assumptions, which we have not independently verified:

1.

3. The Transaction Documents are within the capacity and powers of, and have been or will be duly authorized, executed and delivered by, each of the parties thereto (other than the Company) and constitute or will constitute, when executed and delivered, legal, valid and binding obligations of each of such parties thereto enforceable in accordance with their terms as a matter of the laws of all jurisdictions other than the Cayman Islands.

(c) claims may become barred under statutes of limitation or may be or become subject to defenses of set-off or counterclaim;

3

(d) where obligations are to be performed in a jurisdiction outside the Cayman Islands, they may not be enforceable in the Cayman Islands to the extent that performance would be illegal under the laws of that jurisdiction;

(e) an award of a court of the Cayman Islands may he required to be made in Cayman Islands dollars;

(f) to the extent that any provision of the Transaction Documents is adjudicated to be penal in nature, it will not be enforceable in the courts of the Cayman Islands; in particular, the enforceability of any provision of the Transaction Documents which imposes additional obligations in the event of any breach or default, or of payment or prepayment being made other than on an agreed date may be limited to the extent that it is subsequently adjudicated to be penal in nature and not an attempt to make a reasonable pre-estimate of loss;

(g) to the extent that the performance of any obligation arising under the Transaction Documents would be fraudulent or contrary to public policy, it will not be enforceable in the courts of the Cayman Islands; and

a Cayman Islands court will not necessarily award costs in litigation in accordance with contractual provisions in this regard.

2. If any provision of the Transaction Documents is held to be illegal, invalid or unenforceable, severance of such provision from the remaining provisions will be subject to the discretion of the Cayman Islands courts.

3. The effectiveness of terms of the Transaction Documents excusing any party from a liability or duty otherwise owed or imdemnifying that party from the consequences of incurring such liability or breaching such duty are limited by law.

4. We express no opinion on the effectiveness of any term of the Transaction Documents purporting to restrict the ability of all the parties thereto to amend the terms of such Transaction Document.

With respect to Company Debt Securities to be issued under the Indenture, when (i) the Indenture has been duly qualified under the Trust Indenture Act of 1939, as amended; (ii) the board of directors of the Company (the "Company Board") has taken all necessary corporate action to approve the issuance and terms of such Company Debt Securities, the terms of the offering thereof and related matters; and (iii) such Company Debt Securities have been duly executed, authenticated, issued and delivered in accordance with the provisions of the Indenture and in accordance with the applicable definitive purchase, underwriting or similar agreement approved by the Company Board upon payment of the consideration therefor provided for therein, such Company Debt Securities will be duly authorized and validly issued.

We hereby consent to the use of our name in the prospectus constituting a part of the Registration Statement and in any prospectus supplements related thereto under the heading "Legal Matters" as counsel for the Company who have passed on the validity of the Company Debt Securities being registered by the Registration Statement, and to the use of


this opinion as an exhibit to the Registration Statement. In giving such consent, we do not thereby admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission thereunder.

EXHIBIT 5.3

[Cleary, Gottlieb, Steen & Hamilton Letterhead]

July 19, 2002

Petroleo Brasileiro S.A. - Petrobras
Avenida Republica do Chile, 65
20035-900 - Rio de Janeiro - RJ, Brazil

Petrobras International Finance Company
Anderson Square Building, P.O. Box 714
George Town, Grand Cayman
Cayman Islands, B.W.I

Ladies and Gentlemen:

We have acted as special United States counsel to Petroleo Brasileiro S.A.- Petrobras, a mixed capital company (sociedade de economia mista) organized under the laws of Brazil ("Petrobras"), and Petrobras International Finance Company, an exempted company incorporated with limited liability under the laws of the Cayman Islands ("PIFCo"), in connection with the preparation and filing with the Securities and Exchange Commission (the "Commission") under the Securities Act of 1933, as amended (the "Securities Act"), of a registration statement on Form F-3 (the "Registration Statement") relating to the offering from time to time, together or separately and in one or more series (if applicable), of (i) unsecured debt securities of Petrobras (which may be convertible at the option of the holder thereof into equity securities of Petrobras) (the "Petrobras Debt Securities"), (ii) unsecured debt securities of PIFCo (the "PIFCo Debt Securities" and, together with the Petrobras Debt Securities, the "Debt Securities") accompanied by guarantees or standby purchase agreements of Petrobras, (iii) warrants to purchase


Petrobras Debt Securities (the "Debt Warrants" and, together with the Petrobras Debt Securities and the PIFCo Debt Securities the "Offered Securities") and (iv) certain other securities of Petrobras. The securities being registered under the Registration Statement will have an aggregate initial offering price of up to U.S. $8,000,000,000, or the equivalent thereof in one or more other currencies and will be offered on a continuous and delayed basis pursuant to the provisions of Rule 415 under the Securities Act.

The Petrobras Debt Securities are to be issued under an indenture dated as of July 19, 2002 (the "Petrobras Indenture") between Petrobras and JPMorgan Chase Bank, as trustee. The PIFCo Debt Securities are to be issued under an indenture dated as of July 19, 2002 (the "PIFCo Indenture") between PIFCo and JPMorgan Chase Bank, as trustee. The Debt Warrants are to be issued from time to time under one or more debt warrant agreements (each, a "Debt Warrant Agreement") to be entered into by Petrobras and one or more institutions, as warrant agents (each, a "Warrant Agent"), each to be identified in the applicable Warrant Agreement.

In arriving at the opinions expressed below, we have reviewed the Registration Statement, as amended through the date hereof, including the Petrobras Indenture and the PIFCo Indenture attached thereto as exhibits, and we have made such investigations of law as we have deemed appropriate as a basis for the opinions expressed below. In rendering the opinions expressed below, we have assumed the authenticity of all documents submitted to us as originals and the conformity to the originals of all documents submitted to us as copies, and we have assumed and have not verified the accuracy as to factual matters of each document we have reviewed.

Based on the foregoing, and subject to the further assumptions and qualifications set forth below, it is our opinion that:

1. The Petrobras Debt Securities will be valid, binding and enforceable obligations of Petrobras, entitled to the benefits of the Petrobras Indenture.

2. The PIFCo Debt Securities will be valid, binding and enforceable obligations of PIFCo, entitled to the benefits of the PIFCo Indenture.

3. The Debt Warrrants will be valid, binding and enforceable obligations of Petrobras.

Insofar as the foregoing opinions relate to the validity, binding effect or enforceability of any agreement or obligation of Petrobras or PIFCo, (a) we have assumed that each of Petrobras and PIFCo, as the case may be, and each other party to such agreement or obligation has satisfied or, prior to the issuance of the Offered Securities, will satisfy those legal requirements that are applicable to it to the extent necessary to make such agreement or obligation enforceable against it (except that no such assumption is made as to Petrobras or PIFCo regarding matters of the federal law of the United States of America or the law of the State of New York), (b) such opinions are subject to applicable bankruptcy, insolvency and similar laws affecting creditors' rights generally and to general principles of equity and (c) such

2

opinions are subject to the effect of judicial application of foreign laws or foreign governmental actions affecting creditor's rights.

In rendering the opinions expressed in paragraphs 1 and 2 above, we have assumed that each series of Debt Securities will be issued with an original aggregate principal amount (or, in the case of any Debt Securities issued at original issue discount, an aggregate issue price) of $2,500,000 or more.

In rendering the opinions expressed above, we have further assumed that (i) the Registration Statement and any amendments thereto (including post-effective amendments) will have become effective and comply with all applicable laws, (ii) the Registration Statement will be effective and will comply with all applicable laws at the time the Offered Securities are offered or issued as contemplated by the Registration Statement, (iii) the terms of all Debt Securities will conform to the forms thereof contained in the applicable indenture, and the terms of any Debt Warrants will not violate any applicable law, result in a default under or breach of any agreement or instrument binding upon the Company or violate any requirement or restriction imposed by any court or governmental body having jurisdiction over the Company, (iv) the Debt Securities and Debt Warrants will be sold and delivered to, and paid for by, the purchasers at the price specified in, and in accordance with the terms of, an agreement or agreements duly authorized, executed and delivered by the parties thereto, (v) the Company will authorize the offering and issuance of the Debt Securities and Debt Warrants and will authorize, approve and establish the final terms and conditions thereof and will authorize, approve and establish the terms and conditions of any applicable Warrant Agreement and will take any other appropriate additional corporate action, and (vi) certificates, if required, representing the Debt Securities and Debt Warrants will be duly executed and delivered and, to the extent required by the applicable indenture or Warrant Agreement, duly authenticated and countersigned.

We express no opinion as to the subject matter jurisdiction of any United States federal court to adjudicate any action relating to the Debt Securities or Debt Warrants where jurisdiction based on diversity of citizenship under 28 U.S.C. ss. 1332 does not exist. We note that the designation in Section 1.15 of each of the Petrobras Indenture and the PIFCo Indenture of the U.S. federal courts sitting in New York City as the venue for actions or proceedings relating to the Debt Securities or the Indenture is (notwithstanding the waiver in Section 1.15) subject to the power of such courts to transfer actions pursuant to 28 U.S.C. ss. 1404 (a) or to dismiss such actions or proceedings on the grounds that such a federal court is an inconvenient forum for such an action or proceeding.

We note that the law of the State of New York provides by statute that a judgment or decree rendered in a currency other than the currency of the United States shall be converted into U.S. dollars at a rate of exchange prevailing on the date of entry of the judgment or decree. There is no corresponding federal statute and no controlling federal court decision on this issue. Accordingly, we express no opinion as to whether a federal court would award a judgment in a currency other than U.S. dollars or, if it did so, whether such court would order the conversion of such judgment into U.S. dollars.

The foregoing opinions are limited to the federal law of the United States of America and the law of the State of New York.

3

We hereby consent to the use of our name in the prospectus constituting a part of the Registration Statement and in any prospectus supplements related thereto under the heading "Legal Matters" as counsel for the Company who have passed on the validity of the Debt Securities and Debt Warrants being registered by the Registration Statement, and to the use of this opinion as an exhibit to the Registration Statement. In giving such consent, we do not thereby admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission thereunder.

Very truly yours,

CLEARY, GOTTLIEB, STEEN & HAMILTON
