         material indenture, agreement or instrument to which Petrobras is a

         enforceability of this Agreement or other Transaction Documents to
         which it is a party, except (A) those governmental approvals which have
         been obtained and which remain in full force and effect (i.e. (1) the
         registration of financial operations (Registro de Operacoes Financeiras
         or "ROF") granted by the Central Bank in connection with the prepayment
         transaction contemplated in the Prepayment Agreement, (2) the Brazilian
         National Treasury Secretary manifestation and corresponding

         Transaction Documents not covered by the ROF and (D) those governmental

         other Transaction Documents to which it is a party have been duly
         executed and delivered by Petrobras and is the legal, valid and binding
         obligation of Petrobras enforceable against Petrobras in accordance

                                      -19-

         affecting the rights of creditors generally and by general equitable
         principles of law (whether enforcement is sought by proceedings in
         equity or at law).

                  (f) Governmental Authority. Petrobras has all governmental
         approvals required to carry on its respective businesses as now
         conducted, except where the failure to have such governmental approvals
         could not reasonably be expected to have a Material Adverse Effect.

         the Offering Memorandum, Petrobras and its Subsidiaries (i) are in
         compliance with any and all Environmental Laws, (ii) have received and

         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 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.

                  (h) Litigation. Other than as disclosed in the Offering
         Memorandum, there is no action, suit or proceeding pending against it,
         or to the knowledge of Petrobras threatened against or affecting
         Petrobras, before any governmental authority which if determined
         adversely to Petrobras could reasonably be expected to have a Material
         Adverse Effect.

                  (i) Claims. There is no Tax, labor or other claim pending
         against or, to the knowledge of Petrobras, threatened against or
         affecting Petrobras, which if determined adversely to Petrobras could
         reasonably be expected to have a Material Adverse Effect on Petrobras.

                  (j) Payment of Taxes. Each of Petrobras and its Subsidiaries
         has filed or caused to be filed all tax returns which, to the knowledge
         of Petrobras, are required to be filed, and has paid all Taxes shown to

         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 claims are
         being asserted with respect to any such Taxes, assessments, fees or
         other charges.

                  (k) Compliance. Petrobras is in compliance in all material
         respects with this Agreement and the other Transaction Documents to
         which it is a party.

         clear of any Liens, any adverse claims or any interest of any other
         Person whatsoever, including Taxes and royalties. The Eligible Products
         to be delivered under this Agreement and the Prepayment Agreement shall
         have been produced, handled, transported and shall be delivered in all
         material respects in accordance with all laws, including environmental
         laws, to the extent applicable to Petrobras.

                  (n) Financial Statements and Reports. (i) The audited
         statement of financial condition of Petrobras and its consolidated
         subsidiaries as at December 31, 2000, and the related consolidated
         statements of income and retained earnings of Petrobras and its
         consolidated subsidiaries for the year ended December 31, 2000, present

         earnings of Petrobras and its consolidated subsidiaries for the
         six-month period ended June 30, 2001, reflect only normal recurring
         adjustments necessary for the fair presentation of the consolidated

         whole.

                  (o) No Immunity. Under the laws of Brazil, neither Petrobras
         nor any of its property has any immunity from jurisdiction of any court

         otherwise) other than certain assets subject to a concession granted by
         a governmental authority in Brazil.

         legality, validity, enforceability or admissibility in evidence of this
         Agreement and the other Transaction Documents to which Petrobras is a

         such documents or any other document called for thereunder; provided,
         however, that for the admission of the Transaction Documents to which

         Brazil shall be notarized by a notary public licensed as such under the

         actions to maintain, or cause any of its subsidiaries to maintain, all
         rights, privileges, titles to property, franchises, concessions and the
         like necessary or desirable in the normal conduct of its business,
         activities or operations; provided that, this covenant shall not
         require Petrobras to maintain, or cause any of its subsidiaries to
         maintain, any such right, privilege, title to property or franchise, or
         require Petrobras to preserve the corporate existence of any
         subsidiary, if the board of directors of Petrobras shall determine in
         good faith that (i) the maintenance or preservation thereof is no
         longer necessary or desirable in the conduct of the business of
         Petrobras and that (ii) the failure to do so does not and will not have
         a material adverse effect on Petrobras and its subsidiaries taken as a
         whole or have a material adverse effect on the rights of the Senior
         Certificate Holders, Petrobras Finance or the Enhancers.

                  (c) Maintenance of Properties. Petrobras will, and will cause
         each of its subsidiaries to, maintain and keep in good condition,

         businesses, and will, and will cause each of its subsidiaries to, make
         all necessary repairs, renewals, replacements and improvements thereof,

                                      -22-

     of Petrobras shall determine in good faith that (a) the maintenance or
     preservation thereof is no longer necessary or desirable in the conduct of
     the business of Petrobras and (b) the failure to maintain such tangible
     property does not and will not have a material adverse effect on Petrobras

     Enhancers.

          (d)  Compliance with Laws and Agreements. Petrobras will comply, and

     respects with all applicable laws (including, without limitation,
     Environmental Laws), rules, regulations, orders and directives of any
     government or governmental authority or agency having jurisdiction over
     Petrobras and each subsidiary thereof or their businesses or any of the
     transactions contemplated thereby. Petrobras will also comply, and will
     cause its subsidiaries to comply, with all covenants and other obligations
     contained in any agreements to which they are a party, except where the
     failure to so comply would not have a material adverse effect on Petrobras
     and its subsidiaries taken as a whole or have a material adverse effect on
     the rights of the Senior Certificate Holders, Petrobras Finance or the
     Enhancers.

          (e)  Maintenance of Approvals. Petrobras will, and will cause its
     subsidiaries to, duly obtain and maintain in full force and effect all
     approvals, consents or licenses or any Governmental Authority which are
     necessary under the laws of Brazil, the Cayman Islands or any other
     jurisdiction having jurisdiction over Petrobras and each subsidiary
     thereof, businesses or transaction contemplated thereby, as well as of any
     third-party under any agreement to which Petrobras, or its Subsidiaries, as
     applicable, may be subject in connection with the execution, delivery and
     performance of any of the Transaction Documents or the validity or
     enforceability of any thereof; provided, however, that Petrobras shall be
     under no obligation to seek prior registration with the Central Bank of the
     payment obligations contained in the Transaction Documents which are not
     covered by the Registro de Operacoes Financeiras, and provided, further,
     that approval for such payment obligations with the Central Bank shall only
     be required once enforcement thereof is sought by the Trustee.

     discharged, before the same shall become delinquent, (i) all Taxes levied
     or imposed upon Petrobras or such subsidiary, as the case may be, and (ii)
     all lawful claims for labor, materials and supplies which, if unpaid, might
     by law become a Lien upon the property of Petrobras or such subsidiary, as
     the case may be, provided, however, that neither Petrobras nor any
     subsidiary will be required to pay or discharge, or cause to be paid or
     discharged, any such Tax whose amount, applicability or validity is being
     contested in good faith and, if appropriate, by appropriate legal
     proceedings.

                                      -23-

          (h)  Maintenance of Insurance. Petrobras will, and will cause each of
     its subsidiaries to, keep at all times all of its properties which are of
     insurable nature insured against loss or damage with insurers believed by
     Petrobras to be financially sound, in amounts and covering similar risks as
     are usually insured by similarly situated corporations owning like
     properties in similar geographic areas in accordance with good business
     practice.

          (i)  Maintenance of Books and Records. Petrobras shall, and shall
     cause each of its subsidiaries to, maintain books, accounts and records in
     accordance with U.S. GAAP (in the case of Petrobras) and in the case of its
     subsidiaries, generally accepted accounting principles in the jurisdictions
     where each such Person is organized.

          (j)  Maintenance of Office or Agency. For so long as any Eligible
     Product is required to be supplied under this Agreement and the Prepayment
     Agreement, Petrobras shall maintain in the Borough of Manhattan, The City
     of New York, an office or agency where notices to and demands upon
     Petrobras in respect of the Transaction Documents to which it is a party
     may be served. Initially this office shall be located at Petrobras'
     existing principal U.S. office at 570 Lexington Avenue, 43rd Floor, New
     York, New York 10022-6837. Petrobras agrees not to change the designation
     of such office to another office or to an agent commonly used for such
     purpose without prior notice to the Trustee and designation of a
     replacement office or agency in the City of New York.

          (k)  Ranking. Petrobras will ensure at all times that its monetary
     obligations under this Agreement and each other Transaction Document to
     which it is a party will constitute the general senior unsecured and
     unsubordinated obligations of Petrobras and will rank pari passu, without
     any preferences among themselves, with all other present and future
     unsecured and unsubordinated indebtedness of Petrobras (other than
     obligations preferred by statute or by operation of law) that are not, by
     their terms, expressly subordinated in right of payment to the obligations
     of Petrobras under the Transaction Documents to which it is a party.

          (l)  Notice of Certain Events. Petrobras will give written notice to
     Petrobras Finance, each Enhancer and the Trustee (with a copy to the
     Servicer), as soon as is practicable and in any event within ten days after
     Petrobras becomes aware, or should have reasonably become aware, of the
     occurrence of any Petrobras Default, Accumulation Event or Specified Event
     (each event as defined in the Trust Deed) accompanied by a certificate of
     an Authorized Officer of Petrobras setting forth the details thereof and
     stating what action Petrobras proposes to take with respect thereto.

          (m)  Provision of Financial Statements and Reports. Petrobras will

     the Prepayment Agreement and this Agreement).

     any Senior Certificate Holder, or any prospective purchaser designated by
     such Senior Certificate Holder, financial or other information applicable

     amalgamate with or merge into any corporation or convey, lease or transfer
     substantially all of its properties, assets or revenues to any Person or
     entity unless:

               (i)    either Petrobras is the continuing entity or the Person
          formed by such consolidation or into which Petrobras is merged or that
          acquired or leased such property or assets of Petrobras (the
          "Successor Company") will be a corporation organized and validly
          existing under the laws of Brazil and shall assume (jointly and
          severally with Petrobras unless Petrobras shall have ceased to exist
          as a result of such merger, consolidation or amalgamation), by an
          amendment to this Agreement and the other Transaction Documents to
          which it is a party, all of Petrobras' obligations under this
          Agreement and the other Transaction Documents to which it is a party;

               (ii)   the Successor Company (jointly and severally with
          Petrobras unless Petrobras shall have ceased to exist as a result of
          such merger, consolidation or amalgamation) agrees to indemnify each
          Senior Certificate Holder against any Tax thereafter imposed on such
          Senior Certificate Holder solely as a consequence of such
          consolidation, merger, conveyance, transfer or lease with respect to
          the payment of principal of, and interest on, the Senior Trust
          Certificates;

               (iii)  immediately after giving effect to the transaction, no
          Petrobras Default or Specified Event (as defined under the Trust Deed)
          has occurred and is continuing;

                                      -26-

               (iv)   Petrobras shall have provided to the Trustee a certificate
          of an Authorized Officer of Petrobras and an opinion of counsel, each
          stating that such merger, consolidation, sale, transfer or other
          conveyance or disposition and the amendment to this Agreement and the
          other Transaction Documents comply with the terms of this Agreement
          and the other Transaction Documents and applicable law, and that all
          conditions precedent provided for in this Agreement and the other
          Transaction Documents relating to such transaction have been met; and

               (v)    Petrobras shall have delivered notice of such transaction
          to the Rating Agencies and each Enhancer, which notice shall contain a
          description of such transaction.

          (b)  Negative Pledge. (i) Petrobras will not create or permit any
     Lien, other than a Petrobras Permitted Lien, on any of its assets to secure
     (A) any of its indebtedness or (B) the indebtedness of any other Person,
     unless Petrobras contemporaneously creates or permits the Lien to secure
     equally and ratably its obligations under this Agreement and the other
     Transaction Documents to which it is a party or Petrobras provides other
     security for its obligations under this Agreement and the other Transaction
     Documents to which it is a party as is duly approved by a resolution of the
     Senior Certificate Holders in accordance with the Trust Deed.

               (ii)   Petrobras will not allow any of its subsidiaries to create
          or permit any Lien, other than a Petrobras Permitted Lien, on any of
          such subsidiary's assets to secure (A) any of Petrobras' indebtedness,
          (B) any of its own indebtedness or (C) the indebtedness of any other
          Person, unless Petrobras contemporaneously creates or permits the Lien
          to secure equally and ratably Petrobras' obligations under this
          Agreement and the other Transaction Documents to which it is a party
          or Petrobras provides such other security for its obligations under
          this Agreement and the other Transaction Documents to which it is a
          party as is duly approved by a resolution of the Senior Certificate
          Holders in accordance with the Trust Deed.

          (c)  Transactions with Affiliates. Petrobras shall not, and shall not
     permit any of its subsidiaries to, enter into or carry out (or agree to
     enter into or carry out) any transaction or arrangement with any Affiliate
     (other than as contemplated by the Transaction Documents), except for any
     transaction or arrangement entered into or carried out on terms no less
     favorable to Petrobras or such subsidiary than those which could have been
     obtained in a comparable transaction on an arm's-length basis with a Person
     that is not an Affiliate.

          Whenever any of the covenants contained in Article V or Article VI of
     this Agreement require Petrobras to cause, or not to permit, any of its
     subsidiaries to take an action, such covenant shall be limited to companies
     or corporations more than half the issued voting share capital of which is

notwithstanding any such payment or judgment, to indemnify the recipient against
such loss, and if the Dollars so purchased exceed the sum originally due to the
recipient in Dollars, the recipient agrees to remit to the other such excess.

                            Definition of Bunker Fuel

     "Bunker Fuel" means marine fuels that are burned in the boilers or engines
of ships. Bunker Fuel is generally of two types:

     1. Intermediate Fuel Oil (IFO) or Marine Fuel (MF) - IFO or MF is a blended
oil with a viscosity between heavy fuel oil and cutter stock (middle
distillates) that is formulated to achieve a specific viscosity. IFOs are used
in ships' main engines and occasionally in auxiliary engines. The two most
common types of IFO are 380 cSt and 180 cSt.

     2. Marine Diesel Fuel (MDO) or Marine Gas Oil (MGO) - MDO or MGO is a light
distillate fuel frequently used in auxiliary engines and in the main engines of
military vessels.

     For the purpose of all Transaction Documents, an "export" of Bunker Fuel
shall include any sale of Bunker Fuel in Brazil to ships owned by non-Brazilian
companies.
