of the Federative Republic of Brazil ("Brazil"), proposes to issue and sell to
Bear, Stearns & Co. Inc., Deutsche Bank Securities Inc., HSBC Securities (USA)
Inc. and Santander Central Hispano Investment Securities Inc. (collectively, the
"Underwriters") U.S.$500,000,000 principal amount of its 9.125% Global Notes Due

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

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

certain credit support provided by Petrobras, in the form of a Standby Purchase
Agreement (the "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

     reference therein only prior to the Closing Date) 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

     or otherwise.

          (l) PIFCo has been duly incorporated and is validly existing as a
     limited company in good standing under the laws of the Cayman Islands. Each
     of PIFCo's subsidiaries has been duly incorporated and is validly existing

     otherwise), results of operation or prospects of either of the Companies,

     Agreement, the term "Material Subsidiary" shall mean, as to any person, any

     of such person prepared in accordance with U.S. generally accepted
     accounting principles (or if any such person does not prepare financial

     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.

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

          (p) 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.

          (q) This Underwriting Agreement has been duly authorized, executed and
     delivered by each of the Companies; each of the Indenture, the 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.

          (r) The Notes have been duly authorized, and, when issued under the
     Indenture, authenticated by the Trustee and delivered to and paid for by
     the Underwriters 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.

          (s) 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 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 Standby Purchase Agreement,
     except for statutory liens and preferences.

          (t) 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

     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

     issuances of securities by the Companies and the purchase and distribution
     of the Notes by the Underwriters 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.

          (u) 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,
     mortgage, deed of trust, note agreement, loan agreement or other agreement,
     obligation, condition, covenant or instrument to which either of the
     Companies or any of their subsidiaries is a party or is bound or to which
     any of their property or assets is subject or (iii) any statute, law, rule,
     regulation, judgment, order or decree applicable to either of the Companies
     or any of their subsidiaries, except in the case of clauses (ii) or (iii)
     such as could not reasonably be expected to have a Material Adverse Effect.

          (v) The consolidated historical financial statements of the Companies
     and their consolidated subsidiaries included in the Preliminary Offering
     Document and 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 Preliminary Offering Document and the Final Offering
     Document fairly present, on the basis stated in the Preliminary Offering
     Document and 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 Preliminary Offering Document
     and the Final Offering Document fairly present, on the basis stated in the
     Preliminary Offering Document and the Final Offering Document, the
     information included therein. Except as disclosed in the Preliminary
     Offering Document and 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.

          (w) 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.

          (x) The statistical, industry-related and market-related data included
     in the Preliminary Offering Document and 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.

          (y) Except as set forth or contemplated in the Preliminary Offering
     Document and 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.

          (z) 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 Preliminary Offering
     Document and 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.

          (aa) 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
     Preliminary Offering Document and 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
     Preliminary Offering Document and 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.

          (bb) Both PricewaterhouseCoopers 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 Preliminary Offering Document and 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

     Document relating to 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 the Regulation S-X under the
     Securities Act and the Exchange Act and, in the case of
     PricewaterhouseCoopers 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 Perez Companc S.A. under the standards
     established by the local authorities in the Argentine Republic.

          (cc) 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 charges have been filed and, to the knowledge of such person,
     no material claims are being asserted with respect to any such taxes,
     assessments, fees or other charges.

          (dd) 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.

          (ee) 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.

          (ff) 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.

          (gg) 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.

          (hh) 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.

          (ii) 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.

          (jj) 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.

          (kk) 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.

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

          (mm) 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.

          (nn) 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.

          (oo) 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.

          (pp) 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.

          (qq) 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.

          (rr) None of the Noteholders, the Underwriters 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.

          (ss) 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.

          (tt) 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 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 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 conditions and
in reliance upon the representations and warranties herein set forth, PIFCo
agrees to sell the Notes with an aggregate principal amount of U.S.$500,000,000
to the Underwriters, and the Underwriters agree to purchase the Notes from
PIFCo, at a purchase price of 99.196% of the aggregate principal amount of the

          SECTION 3. Delivery and Payment. (a) Delivery of and payment for the
Notes shall be made at the offices of Shearman & Sterling in New York or such
other place as shall be agreed upon by the parties hereto at 10:00 A.M., New
York City time, on June 27, 2003, or at such time on such later date as the
Underwriters shall designate, which date and time may be postponed by agreement
between the Underwriters 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 Underwriters against payment by the Underwriters of
U.S.$493,730,000 (the "Net Proceeds") to or upon the order of PIFCo by wire
transfer payable in immediately available funds to the account specified in
writing by PIFCo not less than three Business Days prior to the Closing Date.
The Net Proceeds shall represent an amount equal to (i) U.S.$495,980,000 as the
Purchase Price less (ii) an amount payable to the Underwriters equal to .45% of
the U.S.$500,000,000 aggregate principal amount of the Notes to be issued on the
Closing Date or U.S.$2,250,000 (the "Selling Commission"). Delivery of the Notes
shall be made through the facilities of The Depository Trust Company unless the

     inspecting, checking and packaging by the Underwriters 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 Underwriters. Each Underwriter, represents and
warrants to and agrees as to itself with the Companies that:

          (a) Except as set forth in the Final Offering Document, such
     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) Such 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 Underwriters that:

          (a) The Companies will furnish to the Underwriters and to counsel for
     the Underwriters, 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 Underwriters) as any Underwriter
     may reasonably request, including the delivery of copies of the Preliminary
     Prospectus Supplement and of the Final Prospectus Supplement to the
     Underwriters, 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 Underwriters, which
     consent will not be unreasonably withheld.

          (c) The Companies will notify the Underwriters 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 any 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 such 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 such Underwriter and counsel for
     such 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 Underwriters, (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 Underwriters 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 each 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 each Underwriter under the laws of such jurisdictions as
     such 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 Underwriters, 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

the Closing Date (including for this purpose, documents incorporated by
reference therein only prior to the Closing Date), 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 Preliminary Prospectus
Supplement or the Final Offering Document, or in any amendment thereof or
supplement thereto, in reliance upon and in conformity with written information
relating to any Underwriter furnished to the Companies by or on behalf of any
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) Each Underwriter agrees severally and not jointly 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
Underwriters, but only with reference to written information relating to the
Underwriters furnished to the Companies by or on behalf of any Underwriter
specifically for inclusion in the Preliminary Prospectus Supplement or the Final
Offering Document (or in any amendment or supplement thereto) provided that the
Underwriters' 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 any 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 each 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
Underwriters 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
Underwriters (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 each 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 each 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 Underwriters shall be deemed to be equal to the total amount of the
Underwriters' 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 any 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 Underwriters agree
that it would not be just and equitable if contribution pursuant to this Section
8 were determined by pro rata allocation (even if the Underwriters 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 Underwriters within the meaning of either the
Securities Act or the Exchange Act and each director, officer, employee and
agent of any Underwriter shall have the same rights to contribution as such
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, no
Underwriter shall be required to contribute any amount in excess of the amount
by which the Underwriters' total Selling Commission exceeds the amount of any
damage which such 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 Underwriters, 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 each 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 Underwriters 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 any 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,

address); if sent to Deutsche Bank Securities Inc., will be mailed, delivered or
telefaxed to Deutsche Bank Securities Inc., 60 Wall Street, New York, New York

Republica do Chile 65, Rio de Janeiro, RJ 20035-900, Brazil, 20035-901,
Attention: Isabela Alvim.

          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
Underwriters agree 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 any Underwriter, the directors,
officers, employees and agents of any Underwriter, or by any person who controls
any of any 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.
