          which there is no cure) is either incapable of remedy or continues for
          a period of 60 calendar days (inclusive of any time frame contained in
          any such term, covenant, agreement or obligation for compliance
          thereunder) after there has been received by the Company or Petrobras
          from the Trustee or the Holders of at least 25% in principal amount of
          the Outstanding Securities of that series a written notice specifying
          such default or breach and requiring it to be remedied and stating

          purpose; (ii) the Company, Petrobras or any Material Subsidiary
          thereof shall fail to pay any Indebtedness when due or, as the case
          may be, beyond any applicable grace period specified in the underlying

          any such Indebtedness falling within (i), (ii) or (iii) above (as to
          which the time for payment has not been extended by the relevant
          obligees) equals or exceeds U.S.$100,000,000 (or its equivalent in
          another currency);

          from the execution, delivery, enforcement or registration of each Note

          excise or property taxes, charges or similar levies payable by the
          Issuer as provided in this paragraph paid by such Holder of the Notes.
          The Company shall, if European Council Directive 2003/48/EC or any
          other Directive implementing the conclusions of the ECOFIN council
          meeting of November 26-27, 2000 is brought into force, ensure that it
          maintains a paying agent hereunder in a member state of the European
          Union that will not be obliged to withhold or deduct tax pursuant to

Notes, Article 10 of the Original Indenture shall be amended to include the
following:

          "Section 10.20 Negative Pledge

          So long as any Note remains Outstanding, the Company will not create
     or permit any Lien, other than a Permitted Lien, on any of the Company's
     assets to secure (a) any of the Company's Indebtedness or (b) the
     Indebtedness of any other Person, unless the Company contemporaneously
     creates or permits such Lien to secure equally and ratably the Company's
     obligations under the Notes and this Indenture or the Company provides such
     other security for the Notes as is duly approved by a resolution of the
     Holders of the Notes in accordance with this Indenture. In addition, the
     Company will not allow any of the Company's Subsidiaries to create or
     permit any Lien, other than a Permitted Lien, on any of its assets to
     secure (a) any of the Company's Indebtedness, (b) any of its own
     Indebtedness or (c) the Indebtedness of any other Person, unless it
     contemporaneously creates or permits the Lien to secure equally and ratably
     the Company's obligations under the Notes and this Indenture or the Company
     provides such other security for the Notes as is duly approved by a
     resolution of the Holders of the Notes.

          Section 10.21 Transactions with Affiliates

          The Company will not, and will 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, except for any transaction
     or arrangement entered into or carried out on terms no less favorable to
     the Company or the Subsidiary than those which could have been obtained on
     an arm's-length basis with a person that is not an Affiliate. However, this
     requirement will not apply to transactions (i) between Petrobras and the
     Company or any of the Company's Subsidiaries or (ii) except as otherwise
     permitted under clause (i), between or among the Company, Petrobras and any
     of their respective Subsidiaries not involving any other Person so long as
     consummation of any transaction described in this clause (ii) will not have
     a Material Adverse Effect.

          Section 10.22 Currency Rate Indemnity. (a) The Company shall (to the
     extent lawful) indemnify the Trustee and the Holders of the Notes and keep
     them indemnified against:

          (i) in the case of nonpayment by the Company of any amount due to the
     Trustee, on behalf of the Holders of the Notes, under the Indenture any
     loss or damage incurred by any of them arising by reason of any variation
     between the rates of exchange used for the purposes of calculating the
     amount due under a judgment or order in respect thereof and those
     prevailing at the date of actual payment by the Company; and

          (ii) any deficiency arising or resulting from any variation in rates
     of exchange between (i) the date as of which the local currency equivalent
     of the amounts due or contingently due under the Indenture or in respect of
     the Notes is calculated for the purposes of any bankruptcy, insolvency or
     liquidation of the Company, and (ii) the final date for ascertaining the
     amount of claims in such bankruptcy, insolvency or liquidation. The amount
     of such deficiency shall be deemed not to be increased or reduced by any
     variation in rates of exchange occurring between the said final date and
     the date of any bankruptcy, insolvency or liquidation or any distribution
     of assets in connection therewith.

          (b) The Company agrees that, if a judgment or order given or made by
     any court for the payment of any amount in respect of its obligations
     hereunder is expressed in a currency (the "Judgment Currency") other than
     U.S. dollars (the "Denomination Currency"), it will indemnify the relevant
     Holder against any deficiency arising or resulting from any variation in
     rates of exchange between the date at which the amount in the Denomination
     Currency is notionally converted into the amount in the Judgment Currency
     for the purposes of such judgment or order and the date of actual payment
     thereof.

          (c) The above indemnities shall constitute separate and independent
     obligations of the Company from its obligations under the Indenture, will
     give rise to separate and independent causes of action, will apply
     irrespective of any indulgence granted from time to time and will continue
     in full force and effect notwithstanding any judgment or the filing of any
     proof or proofs in any bankruptcy, insolvency or liquidation of the Company
     for a liquidated sum or sums in respect of amounts due under the Indenture
     or the Notes."
