twelve 30-day months) at the Bund Rate plus 55 basis points (the “Euro Make Whole Amount”), plus in each case, accrued interest on the principal amount of such Notes to (but not including) the date of redemption. 

(l) Early Redemption Solely for Tax Reasons. Pursuant to Section 11.08 of the Original Indenture, the Notes

however, that redemption under Section 11.08 of the Original Indenture shall not be available if the 

  
 8 








 
reincorporation was performed in anticipation of a change in, execution of or amendment to any laws or treaties or the official application or interpretation of any laws or treaties of such new
jurisdiction of incorporation that would result in an obligation to pay Additional Amounts.

or franchise, if the Company’s Board of Directors shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company, and that the loss thereof is not disadvantageous in any material respect to
the Holders.” 
 (c) Additional Covenants Applicable to the Notes: As it applies to the Notes,
Article 10 of the Original Indenture shall be amended to include the following: 
 “Section 10.11 Use of
Proceeds. 
 The Company will use the proceeds from the offer and sale of the Notes after the deduction of any commissions
principally for general corporate purposes and to finance Petrobras’ planned capital expenditure under its 2011-2015 Business Plan while maintaining an adequate capital structure and staying within Petrobras’ targeted financial leverage
ratios in accordance with its 2011-2015 Business Plan. 
 Section 10.12 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 Material 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 in accordance with the Indenture. 
 Section 10.13
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 

  
 12 









 (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 euros (the “Denomination Currency”), it will indemnify the relevant Holder and the Trustee 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.”

 13

provisions of Section 1.08 of the Original Indenture and (ii) confirms that (A) its obligations under the Guaranty shall be issued pursuant to the Indenture and (B) it intends for the Holders of the Notes, in addition to those

with the issuance of such Securities pursuant to Section 3.14 hereof, which are an integral part of such Securities.” 

Section 3.05. Taxes; Additional Amounts. For the avoidance of doubt, the Company’s obligations to pay any indemnity with
respect to taxes, including the obligation to pay Additional Amounts pursuant to Section 10.10 of the Original Indenture, shall extend to any payments made by Petrobras pursuant to the Guaranty.

 Common Code: 071697924 
 Principal Amount: €1,250,000,000 

Initial Issuance Date: December 9, 2011 
 This Note is one of a duly authorized issue of notes of PETROBRAS INTERNATIONAL FINANCE COMPANY, an exempted company with limited liability organized under the laws of the Cayman Islands (the
“Issuer”), designated as its 4.875% Global Notes Due 2018 (the “Notes”), issued in an initial aggregate principal amount of ONE BILLION TWO HUNDRED AND FIFTY MILLION EUROS (€1,250,000,000) under the Eighth
Supplemental Indenture (the “Eighth Supplemental Indenture”), effective as of December 9, 2011, by and among the Issuer, Petróleo Brasileiro S.A. – Petrobras, a mixed capital company (sociedade de economia

further supplements thereto with respect to the Notes, the “Indenture”), by and among the Issuer and the Trustee. Reference is hereby made to the Indenture for a statement of the respective rights, limitations of interests,
benefits, obligations and duties thereunder of the Issuer, the Trustee and the Holders, and of the terms upon which the Notes are, and are to be, authenticated and delivered. All capitalized terms used in this Note which are defined in the Indenture
and not otherwise defined herein shall have the meanings assigned to them in the Indenture. 
 The Issuer, for value received,
hereby promises to pay to The Bank of New York Depositary (Nominee) Limited, or its registered assigns, as common depositary for Euroclear System (“Euroclear”) and Clearstream Banking, société anonyme

agency of the Trustee referred to below. 
 As provided for in the Indenture, the Issuer promises to pay interest on the
outstanding principal amount hereof, from the Closing Date, annually on March 7 of each year, (each such date, an “Interest Payment Date”), commencing March 7, 2012, at a rate equal to 4.875% per annum, and will
initially accrue from the date of issuance and thereafter from the last Interest Payment Date to which interest has been paid. Interest payable, and punctually paid or duly provided for, on this Note on any Interest Payment Date will, as provided in

on which it falls due, divided by the actual number of calendar days in the Interest Period in which the relevant period falls (including the first such calendar day but excluding the last). 

The Notes are subject to redemption by the Issuer on the terms and conditions specified in the Indenture. 

This Note does not purport to summarize the Indenture, and reference is made to the Indenture for information with respect to the
respective rights, limitations of interests, benefits, obligations and duties thereunder of the Issuer, the Trustee and the Holders.

Indenture. 
 Modifications of the Indenture may be made by the Issuer and the Trustee only to the extent and in the
circumstances permitted by the Indenture.
