WITNESSETH:

WHEREAS, Petrobras International Finance Company, an exempted company incorporated with limited liability under the laws of the Cayman Islands and a wholly-owned Subsidiary of the Guarantor (the “Issuer”), has entered into an Indenture dated as of December 15, 2006 (the “Original Indenture”) with the Trustee, as supplemented by the amended and restated first supplemental indenture dated as of January 11, 2008, among the Issuer, the Guarantor and the Trustee (the “Reopening Supplemental Indenture”), as further supplemented by the amended and restated first supplemental indenture dated as of March 31, 2010, among the Issuer, the Guarantor and the Trustee (the “2010 Amended and Restated First Supplemental Indenture”), and as further supplemented by the thirteenth supplemental indenture dated as of the date hereof, among the Issuer, the Guarantor and the Trustee (the “Thirteenth Supplemental Indenture”). The Original Indenture, as supplemented by the 2010 Amended and Restated First Supplemental Indenture and the Thirteenth Supplemental Indenture and as amended or supplemented from time to time with respect to the Notes, is hereinafter referred to as the “Indenture”;

WHEREAS, the Issuer has duly authorized the issuance of its notes in such principal amount or amounts as may from time to time be authorized in accordance with the Indenture and has, as of January 11, 2008, issued an additional U.S.$750,000,000 aggregate principal amount of its 5.875% Global Notes due 2018 (the “Reopening Notes”) under the Original Indenture as supplemented by the Reopening Supplemental Indenture (the “Reopening Indenture”). The Reopening Notes are consolidated, form a single series and are fully fungible with the Company’s outstanding 5.875% Global Notes due 2018 originally issued on November 1, 2007 under the Original Indenture as supplemented by the first supplemental indenture, dated as of November 1, 2007, by and among the Issuer, the Guarantor and the Trustee (the “First Supplemental Indenture”), in the aggregate principal amount of U.S.$1,000,000,000 (the “Original Notes” and, together with the Reopening Notes, the “Notes”);

WHEREAS, the Guarantor, in its capacity as the Standby Purchaser (the “Standby Purchaser”), had entered into the Amended and Restated Standby Purchase Agreement (the “Amended and Restated Standby Purchase Agreement”) on January 11, 2008 in order to provide the holders of the Notes (the “Noteholders”) with assurances that, if the Issuer shall fail to make all required payments of principal, interest or other amounts due in respect of the Notes and the Indenture, the Standby Purchaser would be obligated, without any action on the part of the Noteholders, to immediately purchase the rights of the Noteholders to receive such amounts in consideration of the payment by the Standby Purchaser of an amount of funds equal to the amounts then owed by the Issuer under the Indenture and the Notes, subject to the provisions thereof;

WHEREAS, the Guarantor replaced the Amended and Restated Standby Purchase Agreement with the Original Guaranty on March 31, 2010 in order to provide the Noteholders with an irrevocable and unconditional guaranty that, if the Issuer shall fail to make any required payments of principal, interest or other amounts due in respect of the Notes and the Indenture, the Guarantor will pay any such amounts whether at stated maturity, or earlier or later by acceleration or otherwise;

WHEREAS, the Guarantor wishes to amend the Original Guaranty to replace the term “U.S. GAAP” by “Reporting GAAP” in certain sections hereof;

WHEREAS, the Guarantor agrees that it has and will derive substantial direct and indirect benefits from the issuance of the Notes by the Issuer;

WHEREAS, each of the parties hereto is entering into this Amended and Restated Guaranty for the benefit of the other party and for the equal and ratable benefit of the Noteholders;
