Ladies and Gentlemen:

                  Petrobras International Finance Company, a company organized
under the laws of the Cayman Islands ("PIFCo") and a wholly-owned subsidiary of
Petroleo Brasileiro S.A. - Petrobras, a sociedade de economia mista ("Petrobras"
and, collectively with PIFCo, the "Companies") organized and existing under the
laws of the Federative Republic of Brazil ("Brazil"), proposes to issue and sell
to Bear, Stearns & Co. Inc. (the "Underwriter") U.S.$250,000,000 principal
amount of its 9.125% Global Notes Due 2013 (the "Notes"). The Notes are to be
issued under the indenture (the "Original Indenture") dated July 19, 2002
between PIFCo and JPMorgan Chase Bank, as trustee (the "Trustee"), as
supplemented by the Amended and Restated Second Indenture Supplement (the
"Indenture Supplement", and together with the Original Indenture, the
"Indenture") to be dated the Closing Date (as defined herein) between PIFCo and
the Trustee. The Notes to be issued by PIFCo will be evidenced initially by one
or more Registered Global Notes (each a "Global Note") representing the Notes
sold or resold pursuant to a registration statement on Form F-3 under the
Securities Act of 1933, as amended (the "Securities Act"), initially dated July
5, 2002 and as amended on July 19, 2002 and further amended on August 14, 2002,
filed with the Securities and Exchange Commission (the "Commission") (File No.
333-92044) covering the registration of the Notes under the Securities Act and
including the related base prospectus in the form dated August 14, 2002 at the
time such registration statement was declared effective by the Commission (the
"Base Prospectus"). Such registration statement (including the Base Prospectus),
as amended to the date hereof (including any post-effective amendment that
includes a prospectus or prospectus supplement), together with any documents
incorporated by reference therein are hereinafter referred to as the
"Registration Statement." References to the "effective date" of the Registration
Statement shall be deemed to refer to the date the Registration Statement was
declared effective by the Commission.

                  All of PIFCo's obligations under the Notes will have the
benefit of certain credit support provided by Petrobras, in the form of an
Amended and Restated Standby Purchase Agreement (the "Amended and Restated
Standby Purchase Agreement") to be dated the Closing Date between it and the
Trustee, pursuant to which Petrobras will agree, subject to certain conditions,
to purchase from the holders of the Notes their rights to receive payments from
PIFCo in respect of principal, interest and other amounts due on or with respect
to the Notes if not paid by PIFCo within specified time periods. Terms not
otherwise defined herein are used as defined in the Indenture.

Companies jointly and severally represents and warrants to the Underwriter as
set forth below:

         Underwriting Agreement in connection with the offer and sale of the
         Notes meet the requirements set forth in Form F-3 under the Securities
         Act for use of the Registration Statement in connection with the
         offering of the Notes that are the subject of this Agreement.

         Prospectus) is in effect and no proceedings for such purposes are
         pending or, to the best of the Companies' knowledge, threatened by the
         Commission.

                  (c) Petrobras and PIFCO confirm their intention to file with
         the Commission pursuant to Rule 424(b) under the Securities Act a final

         Supplement") to be dated as of the date hereof relating to the Notes
         and the distribution thereof. The Base Prospectus as supplemented by
         the Final Prospectus Supplement in the form in which it shall be filed
         with the Commission pursuant to Rule 424(b), together with any
         documents incorporated by reference therein, is herein referred to as
         the "Final Offering Document."

                  (d) Each of the Companies has filed all the documents required
         to be filed by it with the Commission pursuant to the United States
         Securities Exchange Act of 1934, as amended (the "Exchange Act"),

         year ended December 31, 2002 and Forms 6-K in connection with their
         respective financial statements for the three months ended March 31,

         requirements of the Securities Act, the Exchange Act and the rules and
         regulations thereunder.

         other actions required under the TIA to permit the use of the
         Indenture, the issuance of the Notes thereunder and the execution by
         Petrobras and the Trustee of the Amended and Restated Standby Purchase
         Agreement have been made and taken prior to the date hereof.

         neither Petrobras nor PIFCo has filed any amendment to the Registration
         Statement or supplement to the Final Offering Document which shall not
         have previously been furnished to the Underwriter or of which the
         Underwriter shall not previously have been advised or to which any
         Underwriter shall have reasonably objected in writing.

                  (g) Each of the Registration Statement, as amended, as of the
         time it became effective under the Securities Act, and the Final
         Offering Document as amended or supplemented as of the date hereof and
         as of the Closing Date, contained, contains and will contain all
         disclosures required under applicable laws, including the Securities
         Act and the rules and regulations thereunder. Neither (i) the
         Registration Statement, as amended, as of the time it became effective
         under the Securities Act or (ii) the Final Offering Document as amended
         or supplemented as of the date hereof and as of the Closing Date

         therein) contains or will contain any untrue statement of a material
         fact or omit to state any material fact necessary to make the
         statements therein, in the light of the circumstances under which they
         were made, not misleading. Notwithstanding the foregoing, the Companies
         do not make any representation or warranty as to the information
         contained in or omitted from the Registration Statement or the Final
         Offering Document in reliance upon and in conformity with information
         furnished in writing to the Companies by any Underwriter, specifically
         for inclusion therein which shall consist solely of the first and sixth
         paragraphs under the captions "Plan of Distribution" in the Final
         Prospectus Supplement.

         "controlled by" an "investment company" as such terms are defined in
         the United States Investment Company Act of 1940, as amended (the
         "Investment Company Act"), and the rules and regulations of the
         Commission promulgated thereunder.

                  (i) Neither of the Companies, nor any of their affiliates, nor
         any person acting on their behalf (other than the Underwriter, as to
         which the Companies make no representation or warranty), has paid or
         agreed to pay to any person any compensation for soliciting another to
         purchase (i) the Notes or (ii) any other securities of Petrobras or
         PIFCo within the last 90 days, except in the case of either (i) or (ii)

         which the Companies make no representation or warranty), has, directly
         or indirectly, taken any action designed to cause or which has
         constituted or which might reasonably be expected to cause or result in
         the stabilization or manipulation of the price of any security of
         either of the Companies to facilitate the initial sale or resale of the
         Notes under the Exchange Act, or otherwise.

         Islands. Each of PIFCo's subsidiaries has been duly incorporated and is
         validly existing as a corporation in good standing (to the extent that
         good standing is applicable under applicable law) under the laws of the
         jurisdiction in which it was chartered or organized. Each of PIFCo and
         its subsidiaries has the full corporate power and authority to own or
         lease, as the case may be, and to operate its properties and conduct
         its business as described in the Final Offering Document. PIFCo has the
         full corporate power and authority to enter into and perform its
         obligations under this Underwriting Agreement, the Indenture, the Notes
         and the Amended and Restated Standby Purchase Agreement (collectively,
         the "Transaction Documents"), to which it is a party, and is duly
         qualified to do business as a foreign corporation under the laws of
         each jurisdiction which requires such qualification except where the
         failure to be so qualified will not have a Material Adverse Effect. For
         the purposes of this Underwriting Agreement, the term "Material Adverse
         Effect" shall mean (A) any material adverse effect on the condition
         (financial or otherwise), results of operation or prospects of either
         of the Companies, together with their respective consolidated
         subsidiaries, (B) any material adverse effect on the ability of PIFCo,
         Petrobras or any other person to perform their respective obligations
         under any of the Transaction Documents or (C) any material adverse
         effect on the rights of the Trustee, acting on behalf of the holders of

                  (l) Petrobras has been duly organized and is validly existing
         as a sociedade de economia mista in good standing (to the extent that
         good standing is applicable under applicable law) under the laws of
         Brazil. Each of Petrobras' Material Subsidiaries has been duly
         incorporated and is validly existing as a corporation in good standing
         (to the extent relevant) under the laws of the jurisdiction in which it
         is chartered or organized. Each of Petrobras and its Material
         Subsidiaries is licensed (if and to the extent necessary) and has the
         full corporate power and authority to own or lease, as the case may be,
         and to operate its properties and to conduct its business as described
         in the Registration Statement and the Final Offering Document and to
         enter into and perform its obligations under this Underwriting
         Agreement and the other Transaction Documents to which it is a party,
         and is duly qualified or licensed as a foreign corporation in good
         standing in each jurisdiction which requires such qualification,
         except, in the case of its Material Subsidiaries other than PIFCo,
         where the failure to be so qualified will not have a Material Adverse
         Effect. Petrobras owns, directly or indirectly, all of the outstanding
         equity interests of PIFCo and its other Material Subsidiaries. For the
         purposes of this Underwriting Agreement, the term "Material Subsidiary"
         shall mean, as to any person, any subsidiary of such person which, on
         any given date of determination, accounts for more than 5% of such
         person's total assets, as such total assets are set forth on the most
         recent consolidated financial statements of such person prepared in
         accordance with U.S. generally accepted accounting principles (or if
         any such person does not prepare financial statements in U.S. generally
         accepted accounting principles, consolidated financial statements
         prepared in accordance with such other generally accepted accounting
         principles then applicable to such person).

                  (m) All the outstanding shares of capital stock, if any, of
         each subsidiary of the Companies have been duly and validly authorized
         and issued and are fully paid and nonassessable except, in the case of
         the subsidiaries (other than PIFCo), as would not have a Material
         Adverse Effect, and all outstanding shares of capital stock of the
         subsidiaries are owned by the Companies, as the case may be, either
         directly or through wholly-owned subsidiaries free and clear of any
         perfected security interest or any other security interests, claims,
         liens or encumbrances.

                  (n) The Companies' respective capitalizations are as set forth
         in the Final Offering Document.

                  (o) There have been no material changes with respect to the
         matters disclosed in "Item 11. Qualitative and Quantitative Disclosure
         About Market Risk" in the Form 20-F of Petrobras for the year ended
         December 31, 2002 except as otherwise specified in the Final Offering
         Document.

                  (p) This Underwriting Agreement has been duly authorized,
         executed and delivered by each of the Companies; each of the Indenture,
         the Amended and Restated Standby Purchase Agreement and each other
         document executed and delivered in connection therewith to which either
         of the Companies is party has been duly authorized and, assuming due
         authorization, execution and delivery thereof by each other party to
         those Transaction Documents (other than the Companies), when executed
         and delivered by the Companies, will constitute a legal, valid and
         binding agreement of the Companies, as the case may be, enforceable
         against each of the Companies in accordance with its terms (subject, as
         to the enforcement of remedies, to applicable bankruptcy,
         reorganization, insolvency, moratorium or other similar laws affecting
         creditors' rights generally from time to time in effect and to general
         principles of equity); and the descriptions of the Transaction
         Documents in the Registration Statement and the Final Offering Document
         fairly summarize the rights and obligations of the parties thereto.

                  (q) The Notes have been duly authorized, and, when issued
         under the Indenture, authenticated by the Trustee and delivered to and
         paid for by the Underwriter pursuant to this Underwriting Agreement,
         will have been duly executed, issued and delivered and will constitute
         legal, valid and binding obligations of PIFCo, enforceable in
         accordance with their terms, subject, as to the enforcement of
         remedies, to applicable bankruptcy, reorganization, insolvency,
         moratorium, or other similar laws affecting creditors' rights generally
         from time to time in effect and to general principles of equity and
         will be entitled to the benefits provided by the Indenture as described
         in the Registration Statement and the Final Offering Document.

                  (r) The Notes will constitute the general unsecured and
         unsubordinated obligations of PIFCo and will rank pari passu in
         priority of payment and in right of seniority with all other unsecured
         and unsubordinated obligations of PIFCo that are not, by their terms,
         expressly subordinated in right of payment to the Notes except for
         statutory liens and preferences. The obligations of Petrobras under the
         Amended and Restated Standby Purchase Agreement will constitute the
         general unsecured and unsubordinated obligations of Petrobras and will
         rank pari passu in priority of payment and in right of seniority with
         all other unsecured and unsubordinated obligations of Petrobras that
         are not, by their terms, expressly subordinated in right of payment to
         the rights of the Trustee under the Amended and Restated Standby
         Purchase Agreement, except for statutory liens and preferences.

                  (s) No consent, approval, authorization, filing with or order
         of any court or governmental agency or other regulatory authority or
         body having jurisdiction over either of the Companies or any of their
         respective properties or assets in Brazil, the Cayman Islands or
         elsewhere ("Government Authorities") is required for (i) the valid
         authorization, issuance, sale and delivery of the Notes, or (ii) the
         execution, delivery or performance by the Companies of any of their
         respective obligations under any of the Transaction Documents in the
         manner contemplated in the Registration Statement and the Final
         Offering Document, including, without limitation, making any of the
         applicable payments required to be made after the date hereof under or
         in respect of any of the Transaction Documents, except for (i) the
         filing of the Final Prospectus Supplement pursuant to Rule 424(b) under
         the Securities Act, (ii) such consents as may be required under state
         or foreign securities or blue sky laws and (iii) such filings or
         consents as may be required by the by-laws and rules of the National
         Association of Securities Dealers, Inc. (the "NASD") or NASD

         Prospectus for issuances of securities by the Companies and the
         purchase and distribution of the Notes by the Underwriter and the
         confirmation by the NASD that it has no objection with respect to the
         fairness and reasonableness of the underwriting terms and arrangements,
         each of which has, to the best knowledge of the Companies, been
         obtained and is in full force and effect.

                  (t) Neither of the Companies is currently in violation of its
         charter, by-laws or comparable organizational documents; neither the
         issuance and sale of the Notes, the execution and delivery of any of
         the Transaction Documents nor the consummation of any of the
         transactions described or contemplated therein, nor the fulfillment of
         the terms thereof will conflict with, or give rise to any right to
         accelerate the maturity or require the prepayment, repurchase or
         redemption of any indebtedness under, or result in a breach or
         violation or imposition of any lien, charge or encumbrance upon any
         property or assets of the Companies or any of their subsidiaries
         pursuant to, (i) the charter, by-laws or comparable organizational
         documents of either of the Companies or any of their Material
         Subsidiaries, (ii) the terms of any indenture, contract, lease,

         reasonably be expected to have a Material Adverse Effect.

                  (u) The consolidated historical financial statements of the
         Companies and their consolidated subsidiaries included in the Final
         Offering Document, together with the related notes, have been prepared
         in accordance with accounting principles generally accepted in the
         United States applied on a consistent basis throughout the periods
         involved (except as otherwise noted therein) and present fairly in all
         material respects the financial condition, results of operations and
         cash flows of the Companies as of the dates and for the periods
         indicated; the summary financial information set forth under the
         captions "Summary Financial Information for PIFCo" and "Summary
         Financial Information for Petrobras" in the Final Offering Document
         fairly present, on the basis stated in the Final Offering Document, the
         information included therein. The financial information relating to
         Perez Companc S.A. and its consolidated subsidiaries set forth in the
         Final Offering Document fairly present, on the basis stated in the
         Final Offering Document, the information included therein. Except as
         disclosed in the Final Offering Document, there has been no material
         adverse change in the operations, business, property or assets of or in
         the financial condition of either of the Companies and their
         consolidated subsidiaries, taken as a whole, since December 31, 2002.
         The segment data and other financial and statistical information
         incorporated by reference in the Registration Statement and the Final
         Offering Document present fairly the information included therein and
         have been prepared on a basis consistent with that of the financial
         statements that are incorporated by reference in the Registration
         Statement and the Final Offering Document and the books and records of
         the respective entities presented therein.

                  (v) There are no pro forma or consolidated financial
         statements or other financial statements or data which are required to
         be included or incorporated by reference in the Registration Statement
         and the Final Offering Document in accordance with Regulation S-X under
         the Securities Act which have not been included as so required.

                  (w) The statistical, industry-related and market-related data
         included in the Final Offering Document are based on or derived from
         sources which the Companies reasonably and in good faith believe are
         reliable and accurate, and such data agree with the sources from which
         they are derived.

                  (x) Except as set forth or contemplated in the Final Offering
         Document, neither of the Companies has entered into any transaction or
         agreement (whether or not in the ordinary course of business) material
         to either of the Companies individually or the Companies taken as a
         whole with their consolidated subsidiaries.

                  (y) No action, suit or proceeding by or before any
         Governmental Authority involving the Companies or any of their
         subsidiaries or their property or assets is pending or, to the best
         knowledge of the Companies, threatened, involving or in any way
         relating to (i) this Underwriting Agreement, any of the other
         Transaction Documents or the transactions contemplated herein or
         therein or (ii) any other matter that individually or in the aggregate
         could reasonably be expected to have a Material Adverse Effect, except
         as set forth in or contemplated in the Final Offering Document. Neither
         the Companies nor any of their subsidiaries is in violation of or in
         default with respect to any applicable statute (including, without
         limitation, any applicable provision of the Sarbanes-Oxley Act,
         including any rules and regulations thereunder or related thereto),
         rule, writ, injunction, decree, order or regulation of any Governmental
         Authority having jurisdiction over such Person which is reasonably
         likely to have a Material Adverse Effect.

                  (z) Each of the Companies and each of their respective
         subsidiaries has good and marketable title to all of their properties
         and assets and owns or leases all such properties and assets as are
         both described in the Final Offering Document and necessary to the
         conduct of its operations as presently conducted free and clear of any
         liens, charges, security interests or other encumbrances except such as
         (i) do not materially interfere with the intended use thereof and (ii)
         could not reasonably be expected to have a Material Adverse Effect. All
         leases and subleases material to the business of each of the Companies
         under which either of the Companies holds properties, as described in
         the Final Offering Document, are in full force and effect; and neither
         of the Companies has had any notice that any material claim of any sort
         has been asserted by anyone adverse to the Companies' rights under any
         leases or subleases mentioned above, or affecting or questioning the
         rights thereof to the continued possession of the leased or subleased
         premises under any such lease or sublease, except as would not result
         in a Material Adverse Effect.

                  (aa) Each of PricewaterhouseCoopers Auditores Independentes
         and Ernst & Young Auditores Independentes (who have certified the
         financial statements of the Companies and supporting schedules and
         information of the Companies and their consolidated subsidiaries and
         delivered their report with respect to the audited consolidated
         financial statements and other financial information included in the
         Final Offering Document relating to the Companies and their
         consolidated subsidiaries) and Pistrelli, Henry Martin y Associados
         S.R.L., a member firm of Ernst & Young (who have delivered their report
         with respect to the financial information included in the Final
         Offering Document relating to Petrobras Energia Participaciones S.A. -
         PEPSA (formerly known as Perez Companc S.A.) and its consolidated
         subsidiaries) are independent public accountants within the meaning of
         the Code of Professional Conduct of the American Institute of Certified
         Public Accountants and the applicable requirements of Regulation S-X
         under the Securities Act and the Exchange Act and, in the case of
         PricewaterhouseCoopers Auditores Independentes and Ernst & Young
         Auditores Independentes, are certified public accountants with respect
         to the Companies under the standards established by the local
         authorities in the Cayman Islands and Brazil, and, in the case of
         Pistrelli, Henry Martin y Associados S.R.L., are certified public
         accountants with respect to Petrobras Energia Participaciones S.A. -
         PEPSA (formerly known as Perez Companc S.A.) under the standards
         established by the local authorities in the Argentine Republic.

                  (bb) Each of the Companies and their respective subsidiaries
         has filed or caused to be filed all tax returns which to the knowledge
         of the Companies are required to be filed, and has paid all taxes shown
         to be due and payable on said returns or on any assessments made
         against such person or any of its respective properties and all other
         taxes, assessments, fees or other charges imposed on such person or any
         of its respective properties by, any Governmental Authority (other than
         those the amount or validity of which is currently being contested in
         good faith by appropriate proceedings and with respect to which
         reserves in conformity with generally accepted accounting principles
         have been provided on the books of such person); and no material tax
         liens or material liens with respect to any assessments, fees or other

         assessments, fees or other charges.

                  (cc) The Companies and each of their respective subsidiaries
         are insured by insurers that the Companies reasonably believe to be
         financially sound against such losses and risks and in such amounts as
         are prudent and customary in the businesses and in the geographical
         regions in which they are engaged, except when the failure to do so
         would not have a Material Adverse Effect; and neither of the Companies
         nor any subsidiary thereof has any reason to believe that it will not
         be able to renew its existing insurance coverage as and when such
         coverage expires or to obtain similar coverage from similar insurers as
         may be necessary to continue its business at a cost that would not have
         a Material Adverse Effect.

                  (dd) No subsidiary of the Companies is currently prohibited,
         directly or indirectly, from paying any dividends to either of the
         Companies, from making any other distribution on such subsidiary's
         capital stock, from repaying to the Companies any loans or advances to
         such subsidiary from the Companies or from transferring any of such
         subsidiary's property or assets to the Companies or any other
         subsidiary of the Companies.

                  (ee) The Companies and their subsidiaries possess all material
         licenses, certificates, permits and other authorizations issued by the
         appropriate federal, state or foreign regulatory authorities necessary
         to conduct their respective businesses, and neither of the Companies
         nor any of their subsidiaries has received any notice of proceedings
         relating to the revocation or modification of any such certificate,
         authorization or permit which, singly or in the aggregate, if the
         subject of an unfavorable decision, ruling or finding, could have a
         Material Adverse Effect.

                  (ff) To ensure the legality, validity, enforceability or
         admissibility into evidence of any of the Transaction Documents, it is
         not necessary that any such other document be filed or recorded with
         any court or other authority in Brazil or the Cayman Islands (other
         than such authorizations or filings that have already been obtained or
         made, as applicable), or that any stamp or similar tax be paid in
         either Brazil or the Cayman Islands on or in respect of any such
         document, except as provided in the Registration Statement and the
         Final Offering Document. It is not necessary under the laws of Brazil
         or the Cayman Islands that any of the holders of the Notes be licensed,
         qualified or entitled to carry on business in either Brazil or the
         Cayman Islands by reason of the execution, delivery, performance or
         enforcement of any of the Transaction Documents.

                  (gg) The Companies and each of their respective subsidiaries
         each maintain a system of internal accounting and other controls
         sufficient to provide reasonable assurance that (i) transactions are
         executed in accordance with management's general or specific
         authorizations, (ii) transactions are recorded as necessary to permit
         preparation of financial statements in accordance with accounting
         principles generally accepted in the United States and to maintain
         asset accountability, (iii) access to assets is permitted only in
         accordance with management's general or specific authorization and (iv)
         the recorded accountability for assets is compared with the existing
         assets at reasonable intervals and appropriate action is taken with
         respect to any differences.

                  (hh) The Companies and their respective subsidiaries (i) are
         in compliance with any and all applicable foreign, federal, state and
         local laws and regulations relating to the protection of human health
         and safety, the environment or hazardous or toxic substances or wastes,
         pollutants or contaminants ("Environmental Laws"), (ii) have received
         and are in compliance with all permits, licenses or other approvals
         required of them under the applicable Environmental Laws to conduct
         their respective businesses and (iii) except as described in the
         Registration Statement and the Final Offering Document, have not
         received notice of any actual or potential liability for the
         investigation or remediation of any disposal or release of hazardous or
         toxic substances or wastes, pollutants or contaminants, except in the
         case of clauses (i), (ii) and (iii) above where such non-compliance
         with Environmental Laws, failure to receive required permits, licenses
         or other approvals, or liability would not, individually or in the
         aggregate, have a Material Adverse Effect. Except as set forth in the
         Registration Statement and the Final Offering Document, neither of the
         Companies nor any of their subsidiaries has been named as a
         "potentially responsible party" under the United States Comprehensive
         Environmental Response, Compensation, and Liability Act of 1980, as
         amended, nor has the Company or any such subsidiary been identified as
         the party responsible or potentially responsible for any breach or
         violation of any other similar Environmental Law.

                  (ii) In the ordinary course of its business, the Companies
         periodically review the effect of Environmental Laws on the business,
         operations and properties of the Companies and their subsidiaries, in
         the course of which it identifies and evaluates associated costs and
         liabilities (including, without limitation, any capital or operating
         expenditures required for clean-up, closure of properties or compliance
         with Environmental Laws, or any permit, license or approval, any
         related constraints on operating activities and any potential
         liabilities to third parties). On the basis of such review, the
         Companies have reasonably concluded that such associated costs and
         liabilities would not, singly or in the aggregate, have a Material
         Adverse Effect.

                  (jj) The information set forth in the Registration Statement
         and the Final Offering Document relating to oil and gas reserves, oil
         and gas wells and any other oil and gas related information required to
         be disclosed in such Registration Statement and the Final Offering
         Document has been prepared by the Companies in all material respects on
         the basis disclosed in the Registration Statement and the Final
         Offering Document and conforms in all material respects to the
         requirements of the Securities Act and the Exchange Act, as the case
         may be.

                  (kk) The indemnification and contribution provisions set forth
         in Section 8 hereof do not contravene Brazilian or Cayman Islands law
         or public policy.

                  (ll) The Companies are subject to civil and commercial law in
         respect of their obligations hereunder and the Companies are not, nor
         are any of their properties, assets or revenues subject to any right of
         immunity under Cayman Islands, Brazilian or New York law, from any
         legal action, suit or proceeding, from the giving of any relief in any
         such legal action, suit or proceeding, from set-off or counterclaim,
         from the jurisdiction of any Cayman Islands, Brazilian, New York or
         U.S. federal court, from service of process, attachment upon or prior
         to judgment, or attachment in aid of execution of judgment, or from
         execution of a judgment, or other legal process or proceeding for the
         giving of any relief or for the enforcement of a judgment, in any such
         court with respect to its obligations, liabilities or any other matter
         under or arising out of or in connection herewith; and, to the extent
         that the Companies or any of their properties, assets or revenues may
         have or may hereafter become entitled to any such right of immunity in
         any such court in which proceedings arising out of, or relating to the
         transactions contemplated hereby, may at any time be commenced, the
         Companies have waived or will waive such right to the extent permitted
         by law and have consented to such relief and enforcement as provided
         herein.

                  (mm) The submission of the Companies to the non-exclusive
         jurisdiction of the courts of the Supreme Court of the State of New
         York, County of New York, and the United States District Court for the
         Southern District of New York (each, a "New York court") in Section 13
         hereof and under each of the Transaction Documents, as applicable, is
         legal, valid and binding under the laws of Brazil and the Cayman
         Islands; the appointment of Petrobras' New York office located at 570
         Lexington Avenue, 43rd Floor, New York, New York 10022 as its
         authorized agent for the purpose described in Section 13 below and
         under each of the other Transaction Documents, as applicable, is legal,
         valid and binding under the laws of Brazil and the Cayman Islands; and
         the choice of law provision set forth in Section 14 below and in each
         Transaction Document, as applicable, is legal, valid and binding under
         the laws of Brazil and the Cayman Islands.

                  (nn) Any final judgment for any amount payable by the
         Companies rendered by any court of the State of New York or of the
         United States located in the State of New York having jurisdiction
         under its own domestic laws in respect of any suit, action or
         proceeding against the Companies based upon any Transaction Document
         would be declared enforceable against the Companies by the courts of
         the Cayman Islands or Brazil, as applicable, without re-examination,
         review of the merits of the cause of action in respect of which the
         original judgment was given or relitigation of the matters adjudicated
         upon or payment of any stamp, registration or similar tax or duty, as
         provided in the provisions for enforcement of foreign judgments set
         forth in the Final Prospectus.

                  (oo) No part of the proceeds of the sale of the Notes will be
         used for any purpose that violates the provisions of any of Regulation
         T, U or X of the Board of Governors of the Federal Reserve System or
         any other regulation of such Board of Governors.

                  (pp) Both presently and immediately after giving effect to the
         transactions contemplated hereunder, each of the Companies (i) is and
         will be able to pay its debts as they become due and (ii) is not
         insolvent as defined under applicable Brazilian bankruptcy, insolvency
         or similar law or Cayman Islands bankruptcy, insolvency or similar law.

                  (qq) None of the Noteholders, the Underwriter or the Trustee
         will be deemed resident, domiciled, carrying on business or subject to
         taxation in Brazil or the Cayman Islands solely by the execution,
         delivery, performance or enforcement of any of the Transaction
         Documents or by virtue of the ownership or transfer of a Note or
         Exchange Note or the receipt of payment thereon assuming that none of
         such persons is a resident of Brazil or the Cayman Islands or has a
         permanent establishment or a fixed base in Brazil or the Cayman
         Islands.

                  (rr) There are no Cayman Islands taxes on or by virtue of the
         execution or delivery of this Underwriting Agreement, the Indenture,
         the Notes or any of the other Transaction Documents or any other
         document to be furnished hereunder or thereunder. Payments to be made
         by the Companies or any other party to any of the Transaction Documents
         pursuant to the Transaction Documents will not be subject to Cayman
         Islands taxes. There are no stamp or other issuance or transfer taxes
         or duties or other similar fees or charges required to be paid in
         connection with the execution and delivery of any of the Transaction
         Documents or the consummation of any of the other transactions
         described therein or the issuance and sale by PIFCo of the Notes.

                  (ss) There is no tax, levy, impost, deduction, charge or
         withholding imposed, levied or made by or in Brazil or any political
         subdivision or taxing authority thereof or therein either (i) on or by
         virtue of the execution or delivery of this Underwriting Agreement or
         any of the other Transaction Documents or (ii) on any payment to be
         made by Petrobras to the Trustee or the holders of the Notes pursuant
         to the Amended and Restated Standby Purchase Agreement, except with
         respect to any payment of interest, fees or other income made to a
         party hereto or thereto outside of Brazil from funds of Petrobras in
         Brazil each of which currently would be subject to a withholding tax
         which, as of the date hereof, is levied at the rate of 15%, 25% if the
         beneficiary is domiciled in a tax haven jurisdiction, or such other
         lower rate, as it may be contemplated in a bilateral treaty aimed at
         avoiding double taxation between Brazil and such other country where
         the recipient of the payment has its domicile. Petrobras is permitted
         to make all payments pursuant to the Amended and Restated Standby
         Purchase Agreement free and clear of all taxes, levies, imposts,
         deductions, charges or withholdings imposed, levied or made by or in
         Brazil or any political subdivision or taxing authority thereof or
         therein, and no such payment in the hands of the Trustee will be
         subject to any tax, levy, impost, deduction, charge or withholding
         imposed, levied or made by or in Brazil or any political subdivision or
         taxing authority therein or thereof, in each case except as provided in
         the immediately preceding sentence. Petrobras intends to make all
         payments pursuant to this Agreement from funds offshore Brazil. To
         ensure the legality, validity, enforceability or admissibility in
         evidence of the Transaction Documents in Brazil, it is not necessary
         that the Transaction Documents or any other document be filed or
         recorded with any court or other authority in Brazil, other than the
         notarization of the signatures of the parties signing outside Brazil,
         the subsequent consularization (authentication) of the signature of
         such a notary by a Brazilian consulate official and the subsequent
         translation of the relevant Transaction Document into Portuguese by a
         sworn translator.

                  SECTION 2. Purchase and Sale. Subject to the terms and

Notes from PIFCo, at a purchase price of 104.996388889% of the aggregate
principal amount of the Notes (the "Purchase Price").

                  SECTION 3. Delivery and Payment. (a) Delivery of and payment

such other place as shall be agreed upon by the parties hereto at 10:00 A.M.,
New York City time, on September 18, 2003, or at such time on such later date as
the Underwriter shall designate, which date and time may be postponed by
agreement between the Underwriter and PIFCo (such date and time of delivery and
payment for the Notes being herein called the "Closing Date"). Delivery of the
Notes shall be made to the Underwriter against payment by the Underwriter of
U.S.$261,365,972.22 (the "Net Proceeds") to or upon the order of PIFCo by wire

of the U.S.$250,000,000 aggregate principal amount of the Notes to be issued on
the Closing Date or U.S.$1,125,000 (the "Selling Commission"). Delivery of the

unless the Underwriter shall otherwise instruct.

                  (b) PIFCo agrees to arrange to have the Notes available for
         inspecting, checking and packaging by the Underwriter in New York, New
         York not later than 1:00 p.m. on the Business Day prior to the Closing
         Date.

                  (c) For the purposes of this Underwriting Agreement, the term
         "Business Day" means each Monday, Tuesday, Wednesday, Thursday and
         Friday that is not a day on which banking institutions in the City of
         New York are authorized or obligated by law, executive order or
         regulation to close.

                  SECTION 4. Offering by Underwriter. The Underwriter represents
and warrants to and agrees as to itself with the Companies that:

                  (a) Except as set forth in the Final Offering Document, the
         Underwriter will not engage in any activity that reasonably can be
         expected to cause or result, under the Exchange Act or otherwise, in
         stabilization or manipulation of the price of any security of PIFCo or
         Petrobras to facilitate the sale or resale of the Notes.

                  (b) The Underwriter shall offer the Notes for sale to the
         public upon the terms and conditions set forth in the "Plan of
         Distribution" section in the Final Offering Document.

                  SECTION 5. Covenants. The Companies agree with the Underwriter
that:

                  (a) The Companies will furnish to the Underwriter and to
         counsel for the Underwriter, without charge, during the period referred
         to in paragraph (d) below, as many copies of the Registration Statement
         and the Final Offering Document and any amendments and supplements
         thereto (in each case including all exhibits filed therewith and all
         documents incorporated therein not previously furnished to the
         Underwriter) as any Underwriter may reasonably request, including the
         delivery of copies of the Final Prospectus Supplement to the
         Underwriter, one of which shall be signed by a duly authorized officer
         of the Companies.

                  (b) The Companies will not amend or supplement, during the
         period specified in (d) below, the Registration Statement or the Final
         Offering Document without the prior written consent of the Underwriter,
         which consent will not be unreasonably withheld.

                  (c) The Companies will notify the Underwriter in writing
         immediately (i) of any request by the Commission for any amendment of
         or supplement to the Registration Statement or the Final Offering
         Document or for any additional information, (ii) of the Companies'
         intention to file or prepare any supplement or amendment to the
         Registration Statement or the Final Offering Document, (iii) of the
         mailing or the delivery to the Commission for filing of any amendment
         of or supplement to the Registration Statement or the Final Offering
         Document, (iv) of the issuance by the Commission of any stop order
         suspending the effectiveness of the Registration Statement or any
         post-effective amendment thereto or of the initiation, or the
         threatening, of any proceedings therefor, (v) of the receipt of any
         comments from the Commission, and (vi) of the receipt by the Companies
         of any notification with respect to the suspension of the qualification
         of the Notes for sale in any jurisdiction or the initiation or
         threatening of any proceeding for that purpose. If the Commission shall
         propose or enter a stop order at any time, the Companies will make
         every reasonable effort to prevent the issuance of any such stop order
         and, if issued, to obtain the prompt lifting of such order.

                  (d) If, during such period after the commencement of the
         offering of the Notes the Underwriter or any dealer is required by law
         to deliver a prospectus, any event occurs as a result of which the
         Final Offering Document, as then amended or supplemented, would include
         any untrue statement of a material fact or omit to state any material
         fact necessary to make the statements therein, in the light of the
         circumstances under which they were made, not misleading, or if it
         should be necessary to amend or supplement the Final Offering Document
         to comply with applicable law, the Companies promptly (i) will notify
         the Underwriter of any such event, (ii) subject to the requirements of
         paragraph (b) of this Section 5, will prepare an amendment or
         supplement that will correct such statement or omission or effect such
         compliance and (iii) will supply any supplemented or amended Final
         Offering Document to the Underwriter and counsel for the Underwriter,
         without charge, in such quantities as such Underwriter may reasonably
         request.

                  (e) PIFCo will (i) prepare the Final Prospectus Supplement in
         form reasonably satisfactory to the Underwriter, (ii) file the Final
         Prospectus Supplement with the Commission pursuant to Rule 424(b)
         within 2 Business Days of the date hereof and (iii) advise the
         Underwriter promptly of the filing of the Final Prospectus Supplement
         pursuant to Rule 424(b) or otherwise and of any amendment or supplement
         to the Final Offering Document or Registration Statement or of official
         notice of institution of proceeding for, or the entry of, a stop order
         suspending the effectiveness of the Registration Statement and, if such
         a stop order should be issued, make every reasonable effort to obtain
         the prompt lifting thereof.

                  (f) The Companies will promptly deliver to the Underwriter's
         counsel a signed copy of the Registration Statement, as initially filed
         and all amendments thereto, including all consents and exhibits filed
         therewith, and will maintain in the Companies' files manually signed
         copies of such documents for at least five years after the date of
         filing.

                  (g) PIFCo will arrange, if necessary, for the qualification of
         the Notes for sale by the Underwriter under the laws of such
         jurisdictions as the Underwriter may designate and will maintain such
         qualifications in effect so long as required for the completion of the
         distribution of the Notes; provided, however, that in no event shall
         the Companies be obligated to qualify to do business in any
         jurisdiction where it is not now so qualified or to take any action
         that would subject it to service of process in suits, other than those
         arising out of the offering or sale of the Notes, in any jurisdiction
         where it is not now so subject. The Companies will promptly inform the
         Underwriter, and shall confirm such information in writing, of the
         receipt by either of the Companies of any notification with respect to
         the suspension of the qualification of the Notes for sale in any
         jurisdiction or the initiation or threatening of any proceeding for
         such purpose. The Companies will file such statements and reports as
         may be required by the laws of each jurisdiction in which the Notes
         have been qualified or registered as provided above.

                  (h) Prior to the completion of the distribution of the Notes
         by the Underwriter (as determined by the Underwriter), the Companies
         will not, and will not permit any of their affiliates to, acquire any
         Notes.

                  (i) The Companies will cooperate with the Underwriter and will
         take all such action as is necessary to permit the Notes to be eligible
         for clearance and settlement through DTC.

                  (j) Neither of the Companies will, for so long as the Notes
         are outstanding, be or become, or be or become owned by, an open-end
         investment company, unit investment trust or face-amount certificate
         company that is or is required to be registered under Section 8 of the
         Investment Company Act, and will not be or become, or be or become
         owned by a closed-end investment company required to be registered but
         not registered thereunder.

                  (k) The Companies will not for a period of 45 days following
         the date hereof, without the prior written consent of the Underwriter,
         offer, sell or contract to sell, or otherwise dispose of or enter into
         any transaction which is designed to, or could reasonably be expected
         to, result in the disposition (whether by actual disposition or
         effective economic disposition due to cash settlement or otherwise) by
         the Companies or any of their affiliates or any person in privity with
         the Companies or any of their affiliates, directly or indirectly, or
         announce the offering of, or file a registration statement for, any
         debt securities substantially similar to the Notes issued or guaranteed
         by the Companies (other than the Notes, any export credit agency loans
         and trade-related facilities).

                  (l) The Companies will not and will request their affiliates
         not to offer, sell or solicit offers to buy or otherwise negotiate in
         respect of any security (as defined in the Securities Act) the offering
         of which security could be integrated with the sale of the Notes.

                  (m) The Companies will not take, directly or indirectly, any
         action designed to or which has constituted or which could reasonably
         be expected to cause or result, under the Exchange Act or otherwise, in
         stabilization or manipulation of the price of any security of PIFCo or
         Petrobras to facilitate the sale or resale of the Notes.

                  (n) PIFCo will use the net proceeds received by it from the
         sale of the Notes in the manner specified in the Final Prospectus under
         the caption "Use of Proceeds."

                  (o) Prior to the Closing Date, neither of the Companies nor
         their affiliates will issue any press release or other communications
         directly or indirectly or hold any press conference relating to the
         Notes, without the Underwriter's prior written consent (which shall not
         be unreasonably withheld), unless in the judgment of either of the
         Companies and its counsel, and after notification to the Underwriter,
         such press release or communication is required by law or except as
         issued or held, as the case may be, in accordance with the applicable
         regulations promulgated under the Securities Act.

                  (p) The Companies will pay any stamp, issue, registration,
         transaction or similar documentary taxes and duties, including interest
         and penalties, payable on or in connection with the creation, issue and
         offering of the Notes, or the execution or delivery of the Transaction
         Documents or the enforcement by the Underwriter of this Underwriting
         Agreement against the Companies or any transaction carried out pursuant
         to this Underwriting Agreement; and, in addition to any amount payable
         by it under this Underwriting Agreement, any value-added, turnover or
         similar tax payable in respect of that amount (and references in this
         Underwriting Agreement to such amount shall be deemed to include any
         such taxes so payable in addition to it and express mention of such
         payment of any taxes (if applicable) in any provisions hereof shall not
         be construed as excluding such payment of any taxes in those provisions
         hereof where such express mention is not made); the Companies will
         indemnify the Underwriter against any loss, liability, cost, claim,
         action, demand or expense (including, but not limited to, reasonable
         legal fees) which the Underwriter may incur or which may be made
         against such Underwriter arising out of or in relation to or in
         connection with any failure to pay or delay in paying any such taxes.

                  (q) Neither the sale of the Notes nor the use of the proceeds
         thereof will violate any regulation of the United States Treasury
         Department contained in 31 C.F.R., Chapter V Subpart B, as amended, or
         Executive Orders 12722 and 12724 (55 Fed. Reg. 31803 and 55 Fed. Reg.
         33089) Blocking Iraqi Government Property and Prohibiting Transactions
         with Iraq or the International Money Laundering Statement and Financial
         Anti-Terrorism Act of 2001.

                  (r) The Companies will furnish a copy of each amendment of the
         Transaction Documents to the Underwriter at the Underwriter's address
         set forth in Section 11 hereof.

                  (s) The Companies agree to pay all costs and expenses relating
         to the offering of Notes, including, without limitation, (i) the fees
         and expenses of the Companies' accountants and counsel (including
         Brazilian, Cayman Islands and United States counsel), (ii) the
         preparation, printing or reproduction of the Final Offering Documents
         and all amendments or supplements and all expenses in connection with
         the filing of the Final Offering Documents and any and all amendments
         and supplements thereto with the Commission, (iii) the filing fees
         incident to, and the fees and disbursements of counsel for the

         the costs of delivery (including postage, air freight charges and
         charges for counting and packaging) of such copies of the Final

         in each case, be reasonably requested for use in connection with the
         offering and sale of the Notes, (vii) the preparation, printing,

         including any stamp, transfer or other similar taxes in connection with

         account of, any current or future taxes, levies, imposts, duties,
         charges or other deductions or withholdings levied in any jurisdiction
         from or through which payment is made, unless such deduction or
         withholding is required by applicable law, in which event the Companies
         will pay additional amounts so that the persons entitled to such
         payments will receive the amount that such persons would otherwise have

                  (m) On the Closing Date, none of the events listed below shall
         have occurred and be continuing:

                      (i) a default in the performance or observance by the

                  any material modification of the obligations of either Company
                  or the Trustee hereunder or under the applicable Transaction
                  Documents; or

                      (iii) either Company or the Trustee shall have instituted
                  proceedings to be adjudicated insolvent or a bankrupt or shall
                  have consented to the institution of bankruptcy or insolvency
                  proceedings against it or shall have filed a petition or
                  answer or consent seeking reorganization or relief under any

                  receiver or shall have made an assignment for the benefit of
                  creditors or shall have admitted in writing its inability to
                  pay its debts.

                  (n) Subsequent to the date hereof and on or prior to the
         Closing Date or, if earlier, the dates as of which information is given
         in the Final Offering Document (exclusive of any amendment or
         supplement thereto), there shall not have been (i) any material change
         or decrease in any of the financial line items specified in the letter
         or letters referred to in paragraph (e) of this Section 6 or (ii) any
         change, or any development involving a prospective change, in or
         affecting the condition (financial or otherwise), prospects, earnings,
         business or properties of the Companies and their subsidiaries, taken
         as a whole, whether or not arising from transactions in the ordinary
         course of business, except as set forth or contemplated in the Final
         Offering Document (exclusive of any amendment or supplement thereto)
         the effect of which, in any case referred to in clause (i) or (ii)
         above, is, in the judgment of the Underwriter, so material and adverse
         as to make it impractical or inadvisable to market the Notes as
         contemplated by the Final Offering Document (exclusive of any amendment
         or supplement thereto).

                  (o) The Underwriter shall have received from Cleary, Gottlieb,
         Steen & Hamilton, special United States counsel to the Companies, an
         opinion (including a disclosure letter covering the Final Offering
         Document), dated the Closing Date and addressed to the Underwriter, in
         form and substance reasonably acceptable to the Underwriter.

                  (p) The Underwriter shall have received from Walkers, Cayman
         Islands counsel to the Companies, an opinion, dated the Closing Date
         and addressed to the Underwriter, in form and substance reasonably
         acceptable to the Underwriter.

                  (q) The Underwriter shall have received an opinion (including
         a disclosure opinion covering the Final Offering Document) of internal
         counsel to Petrobras, dated the Closing Date and addressed to the
         Underwriter, in form and substance reasonably acceptable to the
         Underwriter.

                  (r) The Underwriter shall have received an opinion of Pryor,
         Cashman, Sherman & Flynn LLP, external New York counsel to the Trustee,
         dated the Closing Date and addressed to the Underwriter, in form and
         substance reasonably acceptable to the Underwriter.

                  (s) The Underwriter shall have received an opinion (including
         a disclosure opinion covering the Final Offering Document) of Machado,
         Meyer, Sendacz e Opice, special Brazilian counsel for the Underwriter,
         in form and substance reasonably acceptable to the Underwriter (it
         being understood that the Companies shall have furnished to such
         counsel such documents as they request for the purposes of enabling
         them to pass on such matters).

                  (t) The Underwriter shall have received an opinion (including
         a disclosure opinion covering the Final Offering Document) from
         Shearman & Sterling, special United States counsel to the Underwriter,
         in form and substance reasonably acceptable to the Underwriter, dated
         the Closing Date and addressed to the Underwriter, and the Companies
         shall have furnished to such counsel such documents as they request for
         the purpose of enabling them to pass upon such matters.

                  (u) Prior to the Closing Date, the Companies shall have
         furnished to the Underwriter such further information, certificates and
         documents as the Underwriter may reasonably request.

                  (w) None of the events contemplated in Section 9 of this
         Underwriting Agreement shall have occurred.

                  If any of the conditions specified in this Section 6 shall not
have been fulfilled in all material respects when and as provided in this
Underwriting Agreement, or if any of the opinions and certificates mentioned
above or elsewhere in this Underwriting Agreement shall not be in all material
respects reasonably satisfactory in form and substance to the Underwriter and
counsel for the Underwriter, this Underwriting Agreement and all obligations of
the Underwriter hereunder may be canceled at, or at any time prior to, the
Closing Date by the Underwriter. Notice of such cancellation shall be given to
PIFCo in writing or by telephone or facsimile confirmed in writing.

                  The documents required to be delivered by this Section 6 will
be delivered at the office of counsel for the Underwriter, at 599 Lexington
Avenue, New York, N.Y. 10022, on the Closing Date.

                  SECTION 7. Reimbursement of Expenses. If the sale of the Notes
provided for herein is not consummated because any condition to the obligations
of the Underwriter set forth in Section 6 hereof is not satisfied, because of
any termination pursuant to Section 9 hereof or because of any refusal,
inability or failure on the part of either of the Companies to perform any
agreement herein or comply with any provision hereof other than by reason of a
default by the Underwriter, the Companies will reimburse the Underwriter on
demand for all properly documented out-of-pocket expenses (including the fees
and disbursements of counsel) that shall have been incurred by it in connection
with the proposed purchase and sale of the Notes; provided, however that if the
Underwriter resigns without having good commercial reasons for resigning (having
regard to good international capital markets practice), then the Companies shall
be under no obligation to reimburse such expenses. The Companies' liability to
the Underwriter under this Section 7 is joint and several.

                  SECTION 8. Indemnification and Contribution. (a) The Companies
agree to indemnify and hold harmless the Underwriter, the directors, officers,
employees and agents of the Underwriter and each person who controls the
Underwriter within the meaning of either the Securities Act or the Exchange Act
against any and all losses, claims, damages or liabilities, joint or several, to
which they or any of them may become subject under the Securities Act, the
Exchange Act or other federal or state statutory law or regulation, at common
law or otherwise, insofar as such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon (i) any untrue
statement or alleged untrue statement of a material fact contained in (A) the
Registration Statement at the effective date thereof and as of the date of any
amendment thereof or supplement thereto or, (B) the Final Offering Document, or
in any amendment thereof or supplement thereto, in each case as of the date
thereof, the Closing Date (including, for this purpose, documents incorporated
by reference therein), the date of any amendment thereof or supplement thereto
and as of any date delivery thereof is required under applicable law or (ii) the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading, and agrees to
reimburse each such indemnified party, as incurred, for any properly documented
legal or other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, damage, liability or action;
provided, however, that the Companies will not be liable in any such case to the
extent that any such loss, claim, damage or liability arises out of or is based
upon any such untrue statement or alleged untrue statement or omission or
alleged omission made in the Final Offering Document, or in any amendment
thereof or supplement thereto, in reliance upon and in conformity with written
information relating to the Underwriter furnished to the Companies by or on
behalf of the Underwriter specifically for inclusion therein (which shall
consist of solely of the information in the first and sixth paragraphs under the
captions "Plan of Distribution" in the Final Prospectus Supplement). This
indemnity agreement will be in addition to any liability which the Companies may
otherwise have.

                  (b) The Underwriter agrees to indemnify and hold harmless the
Companies, each of their directors, officers, employees and agents, and each
person who controls the Companies within the meaning of either the Securities
Act or the Exchange Act, to the same extent (subject to the proviso set forth
below) as the foregoing indemnity from the Companies to the Underwriter, but
only with reference to written information relating to the Underwriter furnished
to the Companies by or on behalf of the Underwriter specifically for inclusion
in the Final Offering Document (or in any amendment or supplement thereto)
provided that the Underwriter's aggregate liability to the parties set forth
above shall in no event exceed the amount of the Selling Commission. This
indemnity agreement will be in addition to any liability which the Underwriter
may otherwise have.

                  (c) Promptly after receipt by an indemnified party under this
Section 8 of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against the indemnifying party
under this Section 8, notify the indemnifying party in writing of the
commencement thereof; but the failure so to notify the indemnifying party (i)
will not relieve it from liability under paragraph (a) or (b) above unless and
to the extent it did not otherwise learn of such action and such failure results
in the forfeiture by the indemnifying party of substantial rights and defenses
and (ii) will not, in any event, relieve the indemnifying party from any
obligations to any indemnified party other than the indemnification obligation
provided in paragraph (a) or (b) above. The indemnifying party shall be entitled
to appoint counsel of the indemnifying party's choice at the indemnifying
party's expense to represent the indemnified party in any action for which
indemnification is sought (in which case the indemnifying party shall not
thereafter be responsible for the fees and expenses of any separate counsel
retained by the indemnified party or parties except as set forth below);
provided, however, that such counsel shall be reasonably satisfactory to the
indemnified party. Notwithstanding the indemnifying party's election to appoint
counsel to represent the indemnified party in an action, the indemnified party
shall have the right to employ separate counsel (including local counsel), and
the indemnifying party shall bear the reasonable fees, costs and expenses of
such separate counsel if (i) the use of counsel chosen by the indemnifying party
to represent the indemnified party would present such counsel with a conflict of
interest, (ii) the actual or potential defendants in, or targets of, any such
action include both the indemnified party and the indemnifying party and the
indemnified party shall have reasonably concluded that there may be legal
defenses available to it and/or other indemnified parties which are different
from or additional to those available to the indemnifying party, (iii) the
indemnifying party shall not have employed counsel satisfactory to the
indemnified party to represent the indemnified party within a reasonable time
after notice of the institution of such action or (iv) the indemnifying party
shall authorize the indemnified party to employ separate counsel at the expense
of the indemnifying party. An indemnifying party will not, without the prior
written consent of the indemnified parties, settle or compromise or consent to
the entry of any judgment with respect to any pending or threatened claim,
action, suit or proceeding in respect of which indemnification or contribution
may be sought hereunder (whether or not the indemnified parties are actual or
potential parties to such claim or action) unless (x) such settlement,
compromise or judgment (i) includes an unconditional release of the indemnified
party from all liability arising out of such claim, investigation, action or
proceeding and (ii) does not include a statement as to or an admission of fault,
culpability or any failure to act, by or on behalf of the indemnified party, and
(y) the indemnifying party confirms in writing its indemnification obligations
hereunder with respect to such settlement, compromise or judgment.

                  (d) In the event that the indemnity provided in paragraph (a)
or (b) of this Section 8 is unavailable to or insufficient to hold harmless an
indemnified party for any reason, the Companies and the Underwriter agrees to
contribute to the aggregate losses, claims, damages and liabilities (including
legal or other expenses reasonably incurred in connection with investigating or
defending same) (collectively, "Losses") to which the Companies and the
Underwriter may be subject in such proportion as is appropriate to reflect the
relative benefits received by the Companies (on the one hand) and by the
Underwriter (on the other) from the offering of the Notes. If the allocation
provided by the immediately preceding sentence is unavailable for any reason,
the Companies and the Underwriter shall contribute in such proportion as is
appropriate to reflect not only such relative benefits but also the relative
fault of the Companies (on the one hand) and of the Underwriter (on the other)
in connection with the statements or omissions which resulted in such Losses, as
well as any other relevant equitable considerations. Benefits received by the
Companies shall be deemed to be equal to the total net proceeds from the
offering (before deducting expenses) received by PIFCo, and benefits received by
the Underwriter shall be deemed to be equal to the total amount of the
Underwriter's Selling Commission. Relative fault shall be determined by
reference to, among other things, whether any untrue or any alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information provided by the Companies (on the one hand)
or the Underwriter (on the other), the intent of the parties and their relative
knowledge, access to information and opportunity to correct or prevent such
untrue statement or omission. Each of the Companies and the Underwriter agrees
that it would not be just and equitable if contribution pursuant to this Section
8 were determined by pro rata allocation (even if the Underwriter were treated
as one entity for such purpose) or by any other method of allocation which does
not take account of the equitable considerations referred to in subsection (c)
above. Notwithstanding the provisions of this paragraph (d), no person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. For purposes of this Section 8,
each person who controls the Underwriter within the meaning of either the
Securities Act or the Exchange Act and each director, officer, employee and
agent of the Underwriter shall have the same rights to contribution as the
Underwriter, and each person who controls either of the Companies within the
meaning of either the Securities Act or the Exchange Act and each officer and
director of either of the Companies shall have the same rights to contribution
as the Companies, subject in each case to the applicable terms and conditions of
this paragraph (d). Notwithstanding the provisions of this Section 8, the
Underwriter shall not be required to contribute any amount in excess of the
amount by which the Underwriter's total Selling Commission exceeds the amount of
any damage which the Underwriter has otherwise been required to pay by reason of
such untrue statement or alleged untrue statement or omission or alleged
omission.

                  (e) The liability of each of the Companies under this Section
8 is joint and several.

                  SECTION 9. Termination. This Underwriting Agreement shall be
subject to termination in the absolute discretion of the Underwriter, by notice
given to the Companies prior to delivery of and payment for the Notes, if at any
time prior to such time (i) trading in any of the Companies' securities shall
have been suspended by the Sao Paulo Stock Exchange or trading in securities
generally on the New York Stock Exchange or the Sao Paulo Stock Exchange shall
have been suspended or limited or minimum prices shall have been established on
either such exchanges, or (ii) a banking moratorium shall have been declared
either by Federal or New York State authorities or by the relevant banking
authorities in Brazil or the Cayman Islands or if any material disruption in
commercial banking or securities settlement or clearance services shall have
occurred, or (iii) any downgrading shall have occurred in either of the
Companies' corporate credit rating or the rating accorded either of the
Companies' debt securities by any "nationally recognized statistical rating
organization" (as defined for purposes of Rule 436(g) under the Securities Act)
or if any such organization shall have publicly announced that it has under
surveillance or review, with possible negative implications, its rating of any
of the Companies debt securities, or (iv) there shall have occurred any outbreak
or escalation of hostilities, declaration by the United States or Brazil of a
national emergency or war or other calamity (including any terrorist act) or any
crisis the effect of which on financial markets is such as to make it, in the
sole judgment of the Underwriter, impracticable or inadvisable to proceed with
the offering or delivery of the Notes as contemplated by the Final Offering
Document (exclusive of any amendment or supplement thereto).

                  SECTION 10. Representations and Indemnities to Survive. The
respective agreements, representations, warranties, indemnities and other
statements of each of the Companies or their officers and of the Underwriter set
forth in or made pursuant to this Underwriting Agreement will remain in full
force and effect, regardless of any investigation made by or on behalf of the
Underwriter or the Companies or any of the officers, directors or controlling
persons referred to in Section 8 hereof, and will survive delivery of and
payment for the Notes. The provisions of Sections 7 and 8 hereof shall survive
the termination or cancellation of this Underwriting Agreement.

                  SECTION 11. Notices. All communications hereunder will be in
writing and effective only on receipt, and, if sent to Bear, Stearns & Co. Inc.,
will be mailed, delivered or telefaxed to Bear, Stearns & Co. Inc., 383 Madison
Avenue, New York, New York 10179, Attention: Emerging Markets Debt Capital

Agreement, to the Legal and Compliance Department of Bear, Stearns & Co. Inc. at

                  SECTION 12. Successors. This Underwriting Agreement will inure
to the benefit of and be binding upon the parties hereto and their respective
successors and the officers and directors and controlling persons referred to in
Section 8 hereof, and, except as expressly set forth in Section 5(h) hereof, no
other person will have any right or obligation hereunder.

                  SECTION 13. Jurisdiction. Each of PIFCo, Petrobras and the
Underwriter agrees that any suit, action or proceeding against them, arising out
of or based upon this Underwriting Agreement or the transactions contemplated
hereby, may be instituted in any State or federal court in the Borough of
Manhattan, City of New York, New York, or in the competent courts of their own
corporate domiciles with respect to actions brought against any of them as a
defendant, and waive any objection which they may now or hereafter have to the
laying of venue of any such proceeding and any right to which any of them may be
entitled on account of places of residence or domicile, and irrevocably submit
to the jurisdiction of such courts in any suit, action or proceeding. The
Companies have appointed the New York office of Petrobras, located at 570
Lexington Avenue, 43rd Floor, New York, New York 10022 as its authorized agent
(the "Authorized Agent") upon whom process may be served in any suit, action or
proceeding arising out of or based upon this Underwriting Agreement or the
transactions contemplated herein which may be instituted in any State or federal
court in the City of New York, New York, by the Underwriter, the directors,
officers, employees and agents of the Underwriter, or by any person who controls
any of the Underwriter, and expressly accepts the jurisdiction of any such court
in respect of any such suit, action or proceeding. The Companies hereby
represent and warrant that the Authorized Agent has accepted such appointments
and has agreed to act as said agent for service of process, and the Companies
agree to take any and all action, including the filing of any and all documents
that may be necessary to continue such appointment in full force and effect as
aforesaid. Subject to applicable law, service of process upon the Authorized
Agent shall be deemed, in every respect, effective service of process upon each
of the Companies.

                  SECTION 14. Governing Law. This Underwriting Agreement will be
governed by and construed in accordance with the laws of the State of New York.

                  SECTION 15. Currency. Each reference in this Underwriting
Agreement to U.S. dollars is of the essence. To the fullest extent permitted by
law, the obligation of PIFCo in respect of any amount due under this
Underwriting Agreement will, notwithstanding any payment in any other currency
(whether pursuant to a judgment or otherwise), be discharged only to the extent
of the amount in U.S. dollars that the party entitled to receive such payment
may, in accordance with its normal procedures, purchase with the sum paid in
such other currency (after any premium and costs of exchange) on the Business
Day immediately following the day on which such party receives such payment. If
the amount in U.S. dollars that may be so purchased for any reason falls short
of the amount originally due, the applicable Company will pay such additional
amounts, in U.S. dollars, as may be necessary to compensate for the shortfall.
Any obligation of the Companies not discharged by such payment will, to the
fullest extent permitted by applicable law, be due as a separate and independent
obligation and, until discharged as provided herein, will continue in full force
and effect.

                  SECTION 16. Waiver of Immunity. This Underwriting Agreement,
the other Transaction Documents and any other documents delivered pursuant
hereto or thereto, and any actions taken hereunder or thereunder, constitute
commercial acts by each of the Companies. Each of the Companies irrevocably and
unconditionally and to the fullest extent permitted by law, waives, and agrees
not to plead or claim, any immunity from jurisdiction of any court or from any
legal process (whether through service or notice, attachment prior to judgment,
attachment in aid of execution, execution or otherwise) for itself of any of its
property, assets or revenues wherever located with respect to its obligations,
liabilities or any other matter under or arising out of or in connection with
this Underwriting Agreement, the other Transaction Documents, or any document
delivered pursuant hereto or thereunder, in each case for the benefit of each
assigns, it being intended that the foregoing waiver and agreement will be
effective, irrevocable and not subject to withdrawal in any and all
jurisdiction, and, without limiting the generality of the foregoing, agrees that
the waivers set forth in this Section 16 shall have the fullest scope permitted
under the United States Foreign Sovereign Immunities Act of 1976 and are
intended to be irrevocable for the purposes of such act.

                  SECTION 17. Counterparts. This Underwriting Agreement may be
executed in one or more counterparts (including via telecopier), each of which
shall constitute an original and all of which together shall constitute one and
the same instrument.

                  SECTION 18. Entire Agreement. This Underwriting Agreement sets
forth the entire agreement of the parties hereto with respect to the subject
matter hereof.

                  SECTION 19. Headings. The section headings used herein are for
convenience only and shall not affect the construction hereof.
