PRELIMINARY PROSPECTUS SUPPLEMENT
(To Prospectus dated December 18, 2006)

Petrobras International Finance Company

Unconditionally guaranteed by

Petróleo Brasileiro S.A.—PETROBRAS

(Brazilian Petroleum Corporation—Petrobras)

% Global Notes due 2019

     The notes are general, unsecured, unsubordinated obligations of Petrobras International Finance Company, or “PifCo,” a wholly-owned subsidiary of Petróleo Brasileiro S.A.—PETROBRAS, or “Petrobras.” The notes will mature on      , 2019, and will bear interest at the rate of      % per annum. The notes will be unconditionally and irrevocably guaranteed by Petrobras. Interest on the notes is payable on February            and August            of each year, beginning on August , 2009. Due to a change in Brazilian law, in addition to the standby purchase agreements used in prior issuances by PifCo, Petrobras is also allowed to render guaranties in connection with the notes. Petrobras intends to use guaranties in future issuances of notes. The obligations of Petrobras under the guaranty are similar to its obligations under the standby purchase agreements used in prior issuances.

     PifCo will pay additional amounts related to the deduction of certain withholding taxes in respect of certain payments on the notes. PifCo may redeem, in whole or in part, the notes at any time by paying the greater of the principal amount of the notes and the applicable “make-whole” amount, plus, in each case, accrued interest. The notes will also be redeemable without premium prior to maturity at PifCo’s option solely upon the imposition of certain withholding taxes. See “Description of the Notes — Optional Redemption—Redemption for Taxation Reasons.”

     PifCo intends to apply to have the notes approved for listing on the New York Stock Exchange (the “NYSE”).

ABOUT THIS PROSPECTUS SUPPLEMENT

     This document consists of two parts. The first part is the prospectus supplement, which describes the specific terms of the notes PifCo is offering and certain other matters relating to PifCo and Petrobras and their financial condition. The second part, the accompanying prospectus, gives more general information about securities that PifCo and Petrobras may offer from time to time. Generally, references to the prospectus mean this prospectus supplement and the accompanying prospectus combined. If the description of the notes in this prospectus supplement differs from the description in the accompanying prospectus, the description in this prospectus supplement supersedes the description in the accompanying prospectus.

     You should rely only on the information incorporated by reference or provided in this prospectus supplement or in the accompanying prospectus. PifCo and Petrobras have not authorized anyone to provide you with different information. Neither PifCo nor Petrobras is making an offer to sell the notes in any jurisdiction where the offer is not permitted. You should not assume that the information in this prospectus supplement, the accompanying prospectus or any document incorporated by reference is accurate as of any date other than the date of the relevant document.

     In this prospectus supplement, unless the context otherwise requires or as otherwise indicated, references to “Petrobras” mean Petróleo Brasileiro S.A.—PETROBRAS and its consolidated subsidiaries taken as a whole, and references to “PifCo” mean Petrobras International Finance Company, a wholly-owned subsidiary of Petrobras, and its consolidated subsidiaries taken as a whole. Terms such as “we,” “us” and “our” generally refer to both Petrobras and PifCo, unless the context requires otherwise or as otherwise indicated.

DIFFICULTIES OF ENFORCING CIVIL LIABILITIES AGAINST NON-U.S. PERSONS

     Petrobras is a sociedade de economia mista (mixed capital company), a public sector company with some private sector ownership, established under the laws of Brazil, and PifCo is an exempted limited liability company incorporated under the laws of the Cayman Islands. A substantial portion of the assets of Petrobras and PifCo are located outside the Unites States, and at any time all of their executive officers and directors, and certain advisors named in this prospectus supplement, may reside outside the United States. As a result, it may not be possible for you to effect service of process on any of those persons within the United States. In addition, it may not be possible for you to enforce a judgment of a United States court for civil liability based upon the United States federal securities laws against any of those persons outside the United States. For further information on potential difficulties in effecting service of process on any of those persons or enforcing judgments against any of them outside the United States, see “Enforceability of Civil Liabilities” in the accompanying prospectus.

FORWARD-LOOKING STATEMENTS

     Many statements made or incorporated by reference in this prospectus supplement are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, or the “Securities Act,” and Section 21E of the Securities Exchange Act of 1934, as amended, or the “Exchange Act,” that are not based on historical facts and are not assurances of future results. Many of the forward-looking statements contained, or incorporated by reference, in this prospectus supplement may be identified by the use of forward-looking words, such as “believe,” “expect,” “anticipate,” “should,” “planned,” “estimate” and “potential,” among others. We have made forward-looking statements that address, among other things, but are not limited to our:

	•		regional marketing and expansion strategy;
	•		drilling and other exploration activities;
	•		import and export activities;
	•		projected and targeted capital expenditures and other costs, commitments and revenues;
	•		liquidity; and
	•		development of additional revenue sources.

     Because these forward-looking statements involve risks and uncertainties, there are important factors that could cause actual results to differ materially from those expressed or implied by these forward-looking statements. These factors include, among other things:

	•		our ability to obtain financing;
	•		general economic and business conditions, including crude oil and other commodity prices, refining margins and prevailing exchange rates;
	•		our ability to find, acquire or gain access to additional oil and gas reserves and to successfully develop our current ones;
	•		uncertainties inherent in making estimates of our oil and gas reserves including recently discovered oil and gas reserves;
	•		competition;
	•		technical difficulties in the operation of our equipment and the provision of our services;
	•		changes in, or failure to comply with, laws or regulations;
	•		receipt of governmental approvals and licenses;
	•		international and Brazilian political, economic and social developments;
	•		military operations, acts of terrorism or sabotage, wars or embargoes;
	•		the costs and availability of adequate insurance coverage; and
	•		other factors discussed below under “Risk Factors.”

     These statements are not guarantees of future performance and are subject to certain risks, uncertainties and assumptions that are difficult to predict. Therefore, our actual results could differ materially from those expressed or forecast in any forward-looking statements as a result of a variety of factors, including those in “Risk Factors” set forth in this prospectus supplement and in documents incorporated by reference in this prospectus supplement and the accompanying prospectus.

     All forward-looking statements attributed to us or a person acting on our behalf are expressly qualified in their entirety by this cautionary statement. We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information or future events or for any other reason. Because of these uncertainties, potential investors should not rely on any forward-looking statements.

RECENT DEVELOPMENTS

Indebtedness Incurred after September 30, 2008

     Since September 30, 2008, Petrobras or its subsidiaries have incurred the following additional indebtedness:

	•		U.S.$200 million from a pool of foreign banks led by BNP Paribas, and insured by the Italian export credit agency;
	•		U.S.$500 million from the Canadian export credit agency;
	•		U.S.$200 million from Banco Bradesco;
	•		¥75 billion from a syndicate of Japanese banks, and insured by Nippon Export and Investment Insurance;
	•		R$528 million from the Brazilian Development Bank for the Mexilhão Project;
	•		R$2.0 billion from Banco do Brasil;
	•		U.S.$300 million from Banco do Brasil; and
	•		R$1.5 billion from Caixa Econômica Federal.

Bridge Loans

     Petrobras intends to enter into bridge loans with certain international banks to raise an amount of up to US$7 billion in the near future. The loans will be structured as bilateral agreements governed by New York law and will be due in two years. The proceeds of the loans will be used by Petrobras for general corporate purposes, which may include the repayment of trade-related debt and inter-company loans. Petrobras may also use the proceeds of the loans to finance its planned capital expenditures. Any proceeds raised by PifCo or Petrobras through securities offerings after the bridge loans are disbursed will be used to repay such loans and will reduce the total amount outstanding under these loans prior to their maturity dates. Petrobras has not entered into final agreements in connection with these loans but has obtained oral commitments from certain banks. The lenders under the loans may include affiliates of some of the underwriters in this offering. We cannot assure you that Petrobras will be able to obtain bridge loans in the expected amount or at all.

New Oil Law

     The recent discovery of large petroleum and natural gas reserves in the Brazilian pre-salt layer of the regions of the Campos and Santos basins has prompted discussions on possible changes to the existing Oil Law. The Brazilian government created an inter-ministerial committee in 2008 to draft a proposal for a new Oil Law. The committee has not yet made a formal recommendation to the Brazilian government on this matter and no legislation has been submitted to the congress.

     Based on articles published in the Brazilian media, we understand that the new regulatory model may include:

	•		production sharing agreements, instead of the current concession model, in which private companies such as Petrobras would act as service providers;
	•		a new state-owned company that would own and manage the large oil reserves of the pre-salt area that are not subject to concessions previously granted;
	•		partnerships between the Brazilian government and private oil companies to explore oil and gas from the Brazilian pre-salt layer; and
	•		an increase in applicable royalties and taxes.

     We cannot estimate the impact that any change to the Oil Law would have on Petrobras or when the new law would become effective. Nonetheless, we believe there is likely to be an increase in royalties and taxes payable to the Brazilian government as a result of exploration of the oil and gas reserves in the pre-salt layer.

RISK FACTORS

     Our annual report on Form 20-F for the year ended December 31, 2007, which is incorporated by reference herein, includes extensive risk factors relating to our business and to Brazil. You should carefully consider those risks and the risks described below, as well as the other information included or incorporated by reference into this prospectus supplement and the accompanying prospectus, before making a decision to invest in the notes.

Risks Relating to PifCo’s Debt Securities

The market for the notes may not be liquid.

     The notes are not listed on any securities exchange and are not quoted through an automated quotation system. We intend to apply to have the notes approved for listing on the New York Stock Exchange. We can make no assurance as to the liquidity of or trading markets for the notes offered by this prospectus supplement. We cannot guarantee that holders will be able to sell their notes in the future. If a market for the notes does not develop, holders may not be able to resell the notes for an extended period of time, if at all.

Restrictions on the movement of capital out of Brazil may impair your ability to receive payments on the guaranty and restrict Petrobras’ ability to make payments to PifCo in U.S. Dollars.

     The Brazilian government may impose temporary restrictions on the conversion of Brazilian currency into foreign currencies and on the remittance to foreign investors of proceeds from their investments in Brazil. Brazilian law permits the Brazilian government to impose these restrictions whenever there is a serious imbalance in Brazil’s balance of payments or there are reasons to foresee a serious imbalance.

     The Brazilian government imposed remittance restrictions for approximately six months in 1990. Similar restrictions, if imposed, could impair or prevent the conversion of payments under the guaranty from reais into U.S. Dollars and the remittance of the U.S. Dollars abroad, or prevent Petrobras from making funds available to PifCo in U.S. Dollars abroad.

     In addition, payments by Petrobras under the guaranty and payments to PifCo for the import of oil, the expected source of PifCo’s cash resources to pay its obligations under the notes, do not currently require approval by or registration with the Central Bank of Brazil. There may be other regulatory requirements that Petrobras will need to comply with in order to make such payments. The Central Bank of Brazil may nonetheless impose prior approval requirements on the remittance of U.S. Dollars abroad. Petrobras would not need any prior or subsequent approval from the Central Bank of Brazil to use funds it holds abroad to comply with its obligations under the guaranty or make payments to PifCo.

     If Brazilian law were to impose restrictions, limitations or prohibitions on Petrobras’ ability to convert reais into U.S. Dollars, Petrobras may not be able to pay its obligations under the guaranty in U.S. Dollars and PifCo may not have sufficient U.S. Dollar funds available to make payment on the notes. In the event that the holders of the notes receive payments in reais, it may not be possible to convert these amounts into U.S. Dollars.

Petrobras would be required to pay judgments of Brazilian courts enforcing its obligations under the guaranty only in reais.

     If proceedings were brought in Brazil seeking to enforce Petrobras’ obligations in respect of the guaranty, Petrobras would be required to discharge its obligations only in reais. Under Brazilian exchange control regulations, an obligation to pay amounts denominated in a currency other than reais, which is payable in Brazil pursuant to a decision of a Brazilian court, may be satisfied in reais at the rate of exchange, as determined by the Central Bank of Brazil, in effect on the date of payment.

A finding that Petrobras is subject to U.S. bankruptcy laws and that the guaranty executed by it was a fraudulent conveyance could result in the relevant PifCo holders losing their legal claim against Petrobras.

     PifCo’s obligation to make payments on the notes is guaranteed by Petrobras. Petrobras has been advised by its external U.S. counsel that the guaranty is valid and enforceable in accordance with the laws of the State of New York. In addition, Petrobras has been advised by its general counsel that the laws of Brazil do not prevent the guaranty from being valid, binding and enforceable against Petrobras in accordance with its terms. In the event that U.S. federal fraudulent conveyance or similar laws are applied to the guaranty, and Petrobras, at the time it issued the guaranty:

	•		was or is insolvent or rendered insolvent by reason of its entry into the guaranty;
	•		was or is engaged in business or transactions for which the assets remaining with it constituted unreasonably small capital; or
	•		intended to incur or incurred, or believed or believes that it would incur, debts beyond its ability to pay such debts as they mature; and
	•		in each case, intended to receive or received less than reasonably equivalent value or fair consideration therefor,

then Petrobras’ obligations under the guaranty could be avoided, or claims with respect to the guaranty could be subordinated to the claims of other creditors. Among other things, a legal challenge to the guaranty on fraudulent conveyance grounds may focus on the benefits, if any, realized by Petrobras as a result of PifCo’s issuance of the notes supported by such guaranty. To the extent that the guaranty is held to be a fraudulent conveyance or unenforceable for any other reason, the holders of the PifCo notes supported by the guaranty would not have a claim against Petrobras under such guaranty and will solely have a claim against PifCo. Petrobras cannot assure you that, after providing for all prior claims, there will be sufficient assets to satisfy the claims of the PifCo holders relating to any avoided portion of the guaranty.

USE OF PROCEEDS

     PifCo intends to use the net proceeds from the sale of the notes for general corporate purposes, which may include the financing of the purchase of oil product imports and the repayment of existing trade-related debt and inter-company loans. PifCo may also lend some portion of the net proceeds to Petrobras, which Petrobras would use for general corporate purposes and to finance its planned capital expenditures.

DESCRIPTION OF THE NOTES

     The following description of the terms of the notes supplements and modifies the description of the general terms and provisions of debt securities and the indenture set forth in the accompanying prospectus, which you should read in conjunction with this prospectus supplement. In addition, we urge you to read the indenture and the second supplemental indenture because they, and not this description, will define your rights as holders of the notes. If the description of the terms of the notes in this summary differs in any way from that in the accompanying prospectus, you should rely on this summary. You may obtain copies of the indenture and the second supplemental indenture upon written request to the trustee or with the SEC at the addresses set forth under “Where You Can Find More Information.”

Second Supplemental Indenture

     PifCo will issue the notes under an indenture dated as of December 15, 2006 between PifCo and The Bank of New York Mellon (formerly “The Bank of New York”), a New York banking corporation, as trustee, as supplemented by the second supplemental indenture dated as of the closing date, which provides the specific terms of the notes offered by this prospectus supplement, including granting noteholders rights against Petrobras under the guaranty. Whenever we refer to the indenture in this prospectus supplement, we are referring to the indenture as supplemented by the second supplemental indenture.

General

     The notes will be general, senior, unsecured and unsubordinated obligations of PifCo having the following basic terms:

     The title of the notes will be the      % Global Notes due 2019;

     The notes will:

	•		be issued in an aggregate principal amount of U.S.$ ;
	•		mature on      , 2019;

	•		bear interest at a rate of      % per annum from        2009, the date of issuance of the notes, until maturity and until all required amounts due in respect of the notes have been paid;
	•		be issued in global registered form without interest coupons attached;
	•		be issued and may be transferred only in principal amounts of U.S.$2,000 and in integral multiples of U.S.$1,000 in excess thereof; and
	•		be unconditionally guaranteed by Petrobras on terms comparable to the standby purchase agreements previously entered into by Petrobras pursuant to a guaranty described below under “Guaranty.”

	•		Interest on the notes will be paid semiannually on            and            of each year (each of which we refer to as an “interest payment date”), commencing on      , 2009, and the regular record date for any interest payment date will be the day preceding that date; and
	•		In the case of amounts not paid by PifCo under the indenture and the notes (or Petrobras under the guaranty), interest will continue to accrue on such amounts at a default rate equal to 0.5% in excess of the interest rate on the notes, from and including the date when such amounts were due and owing and through and including the date of payment of such amounts by PifCo or Petrobras.

     Despite the Brazilian government’s ownership interest in Petrobras, the Brazilian government is not responsible in any manner for PifCo’s obligations under the notes and Petrobras’ obligations under the guaranty.

Guaranty

     Petrobras will unconditionally and irrevocably guarantee the full and punctual payment when due, whether at the maturity date of the notes, or earlier or later by acceleration or otherwise, of all of PifCo’s obligations now or hereafter existing under the indenture and the notes, whether for principal, interest, make-whole premium, fees, indemnities, costs, expenses or otherwise. The guaranty will be unsecured and will rank equally with all of Petrobras’ other existing and future unsecured and unsubordinated debt. See “Description of the Guaranty.”

     The notes will be issued in global registered form with The Depository Trust Company, or “DTC,” as depositary. For further information in this regard, see “Clearance and Settlement.”

Events of Default

     The following events will be events of default with respect to the notes:

	•		PifCo does not pay the principal on the notes within three calendar days of its due date and the trustee has not received such amounts from Petrobras under the guaranty by the end of that three-day period.
	•		PifCo does not pay interest or other amounts, including any additional amounts, on the notes within 30 calendar days of their due date and the trustee has not received such amounts from Petrobras under the guaranty by the end of that thirty-day period.
	•		PifCo or Petrobras remains in breach of any covenant or any other term of the indenture or the guaranty for 60 calendar days (inclusive of any cure period contained in any such covenant or other term for compliance thereunder) after receiving a notice of default stating that it is in breach. The notice must be sent by either the trustee or holders of 25% of the principal amount of the notes.
	•		The maturity of any indebtedness of PifCo or Petrobras or a material subsidiary in a total aggregate principal amount of U.S.$100,000,000 (or its equivalent in another currency) or more is accelerated in accordance with the terms of that indebtedness, it being understood that prepayment or redemption by us or the material subsidiary of any indebtedness is not acceleration for this purpose;
	•		One or more final and non-appealable judgments or final decrees is entered against PifCo, Petrobras or a material subsidiary involving in the aggregate a liability (not paid or fully covered by insurance) of U.S.$100,000,000 (or its equivalent in another currency) or more, and all such judgments or decrees have not been vacated, discharged or stayed within 120 calendar days after rendering of that judgment.
	•		PifCo, Petrobras or any material subsidiary stop paying or admits that it is generally unable to pay its debts as they become due, is adjudicated or found bankrupt or insolvent or is ordered by a court or passes a resolution to dissolve.
	•		PifCo, Petrobras or any material subsidiary commences voluntarily proceedings under any applicable liquidation, insolvency, composition, reorganization or any other similar laws, or files an application for the appointment of an administrator, receiver or other similar official in relation to PifCo, Petrobras or any material subsidiary, or any events occur or action is taken that has effects similar to those events or actions described in this paragraph.
	•		PifCo, Petrobras or any material subsidiary enters into any composition or other similar arrangement with its creditors (such as a concordata, which is a type of liquidation agreement), or proceedings are initiated against PifCo, Petrobras or any material subsidiary under applicable bankruptcy, insolvency or intervention law or

			law with similar effect and is not discharged or removed within 90 calendar days, or an administrator, receiver or similar official is appointed in relation to, or a distress, execution, attachment, sequestration or other process is levied, enforced upon, sued out or put in force against, the whole or a substantial part of the undertakings or assets of PifCo, Petrobras or any material subsidiary and is not discharged or removed within 90 calendar days, or any events occur or action is taken that has effects similar to those events or actions described in this paragraph.
	•		The notes, the indenture, the guaranty, or any part of those documents, ceases to be in full force and effect or binding and enforceable against PifCo or Petrobras, or it becomes unlawful for PifCo or Petrobras to perform any material obligation under any of the foregoing documents to which it is a party.
	•		PifCo or Petrobras contests the enforceability of the notes, the indenture or the guaranty, or denies that it has liability under any of the foregoing documents to which it is a party.
	•		Petrobras fails to retain at least 51% direct or indirect ownership of the outstanding voting and economic interests (equity or otherwise) of and in PifCo.

     For purposes of the events of default:

	•		“indebtedness” means any obligation (whether present or future, actual or contingent and including any guaranty) for the payment or repayment of money which has been borrowed or raised (including money raised by acceptances and all leases which, under generally accepted accounting principles in the United States, would be a capital lease obligation); and
	•		“material subsidiary” means a subsidiary of PifCo or Petrobras which on any given date of determination accounts for more than 10% of Petrobras’ total consolidated assets (as set forth on Petrobras’ most recent balance sheet prepared in accordance with U.S. GAAP).

Covenants

     PifCo will be subject to the following covenants with respect to the notes:

     Payment of Principal and Interest

     PifCo will duly and punctually pay the principal of and any premium and interest and other amounts (including any additional amounts in the event withholding and other taxes are imposed in Brazil or the jurisdiction of incorporation of PifCo) on the notes in accordance with the notes and the indenture.

     Maintenance of Corporate Existence

     PifCo will maintain its corporate existence and take all reasonable actions to maintain all rights, privileges and the like necessary or desirable in the normal conduct of business, activities or operations, unless PifCo’s board of directors determines that preserving PifCo’s corporate existence is no longer desirable in the conduct of PifCo’s business and is not disadvantageous in any material respect to holders.

     Maintenance of Office or Agency

     So long as notes are outstanding, PifCo will maintain in the Borough of Manhattan, the City of New York, an office or agency where notices to and demands upon it in respect of the indenture and the notes may be served.

     Initially, this office will be located at 570 Lexington Avenue, New York, New York 10022-6837. PifCo will not change the designation of the office without prior written notice to the trustee and designating a replacement office in the same general location.

     Ranking

     PifCo will ensure that the notes will at all times constitute its general senior, unsecured and unsubordinated obligations and will rank pari passu, without any preferences among themselves, with all of its other present and future unsecured and unsubordinated obligations (other than obligations preferred by statute or by operation of law).

     Use of Proceeds

     PifCo will use the proceeds from the offer and sale of the notes after the deduction of any commissions principally for general corporate purposes, including the financing of the purchase of oil product imports and the repayment of existing trade-related debt and inter-company loans. PifCo may also lend some portion of the net proceeds to Petrobras, which Petrobras would use for general corporate purposes and to finance its planned capital expenditures.

     Statement by Officers as to Default and Notices of Events of Default

     PifCo will deliver to the trustee, within 90 calendar days after the end of its fiscal year, an officer’s certificate, stating whether or not to the best knowledge of its signers PifCo is in default on any of the terms, provisions and conditions of the indenture or the notes (without regard to any period of grace or requirement of notice provided under the indenture) and, if PifCo (or any obligor) are in default, specifying all the defaults and their nature and status of which the signers may have knowledge. Within 10 calendar days (or promptly with respect to certain events of default relating to PifCo’s insolvency and in any event no later than 10 calendar days) after PifCo becomes aware or should reasonably become aware of the occurrence of any default or event of default under the indenture or the notes, it will notify the trustee in writing of the occurrence of such default or event of default.

     Provision of Financial Statements and Reports

     In the event that PifCo files any financial statements or reports with the SEC or publishes or otherwise makes such statements or reports publicly available in Brazil, the United States or elsewhere, PifCo will furnish a copy of the statements or reports to the trustee within 15 calendar days of the date of filing or the date the information is published or otherwise made publicly available.

     PifCo will provide, together with each of the financial statements delivered as described in the preceding paragraph, an officer’s certificate stating (i) that a review of PifCo’s activities has been made during the period covered by such financial statements with a view to determining whether PifCo has kept, observed, performed and fulfilled its covenants and agreements under this indenture; and (ii) that no event of default, or event which with the giving of notice or passage of time or both would become an event of default, has occurred during that period or, if one or more have actually occurred, specifying all those events and what actions have been taken and will be taken with respect to that event of default or other event.

     Delivery of these reports, information and documents to the trustee is for informational purposes only and the trustee’s receipt of any of those will not constitute constructive notice of any information contained therein or determinable from information contained therein, including PifCo’s compliance with any of its covenants under the indenture (as to which the trustee is entitled to rely exclusively on officer’s certificates).

     Appointment to Fill a Vacancy in Office of Trustee

     PifCo, whenever necessary to avoid or fill a vacancy in the office of trustee, will appoint a successor trustee in the manner provided in the indenture so that there will at all times be a trustee with respect to the notes.

     Payments and Paying Agents

     PifCo will, prior to 3:00 p.m., New York City time, on the business day preceding any payment date of the principal of or interest on the notes or other amounts (including additional amounts), deposit with the trustee a sum sufficient to pay such principal, interest or other amounts (including additional amounts) so becoming due.

     Additional Amounts

     Except as provided below, PifCo will make all payments of amounts due under the notes and the indenture and each other document entered into in connection with the notes and the indenture without withholding or deducting any present or future taxes, levies, deductions or other governmental charges of any nature imposed by Brazil, the jurisdiction of PifCo’s incorporation or any jurisdiction in which PifCo appoints a paying agent under the indenture, or any political subdivision of such jurisdictions (the “taxing jurisdictions”). If PifCo is required by law to withhold or deduct any taxes, levies, deductions or other governmental charges, PifCo will make such deduction or withholding, make payment of the amount so withheld to the appropriate governmental authority and pay the holders any additional amounts necessary to ensure that they receive the same amount as they would have received without such withholding or deduction.

     PifCo will not, however, pay any additional amounts in connection with any tax, levy, deduction or other governmental charge that is imposed due to any of the following (“excluded additional amounts”):

	•		the holder has a connection with the taxing jurisdiction other than merely holding the notes, receiving principal or interest payments on the notes, or enforcing any rights with respect to the notes (such as citizenship, nationality, residence, domicile, or existence of a business, a permanent establishment, a dependent agent, a place of business or a place of management, present or deemed present within the taxing jurisdiction);
	•		any tax imposed on, or measured by, net income;
	•		the holder fails to comply with any certification, identification or other reporting requirements concerning its nationality, residence, identity or connection with the taxing jurisdiction, if (x) such compliance is required by applicable law, regulation, administrative practice or treaty as a precondition to exemption from all or a part of the tax, levy, deduction or other governmental charge, (y) the holder is able to comply with such requirements without undue hardship and (z) at least 30 calendar days prior to the first payment date with respect to which such requirements under the applicable law, regulation, administrative practice or treaty will apply, PifCo has notified all holders or the trustee that they will be required to comply with such requirements;
	•		the holder fails to present (where presentation is required) its notes within 30 calendar days after PifCo has made available to the holder a payment under the notes and the indenture, provided that PifCo will pay additional amounts which a holder would have been entitled to had the notes owned by such holder been presented on any day (including the last day) within such 30 calendar day period;
	•		any estate, inheritance, gift, value added, use or sales taxes or any similar taxes, assessments or other governmental charges;
	•		where such taxes, levies, deductions or other governmental charges are imposed on a payment on the notes to an individual and are required to be made pursuant to any European Union Council Directive implementing the conclusions of the ECOFIN Council meeting of November 26-27, 2000, on the taxation of savings income, or any law implementing or complying with, or introduced in order to conform to, such directive;
	•		where the holder could have avoided such taxes, levies, deductions or other governmental charges by requesting that a payment on the notes be made by, or presenting the notes for payment to, another paying agent of PifCo located in a member state of the European Union; or
	•		where the holder would have been able to avoid the tax, levy, deduction or other governmental charge by taking reasonable measures available to such holder.

     PifCo shall promptly pay when due any present or future stamp, court or documentary taxes or any other excise or property taxes, charges or similar levies that are imposed by Brazil, the jurisdiction of PifCo’s incorporation or any other jurisdiction in which PifCo appoints a paying agent or any political subdivision or any taxing authority

thereof or therein that arise from any payment under the notes or under any other document or instrument referred in the indenture or from the execution, delivery, enforcement or registration of the notes or any other document or instrument referred to in the indenture. PifCo shall indemnify and make whole the holders for any present or future stamp, court or documentary taxes or any other excise or property taxes, charges or similar levies payable by PifCo as provided in this paragraph paid by such holder. PifCo shall maintain a paying agent hereunder in a member state of the European Union that will not be obliged to withhold or deduct tax pursuant to the European Council Directive 2003/48/EC or any other Directive implementing the conclusions of the ECOFIN council meeting of November 26-27, 2000, or any law implementing or complying with, or introduced in order to conform to, such Directive.

     Negative Pledge

     So long as any note remains outstanding, PifCo will not create or permit any lien, other than a PifCo permitted lien, on any of its assets to secure (i) any of its indebtedness or (ii) the indebtedness of any other person, unless PifCo contemporaneously creates or permits such lien to secure equally and ratably its obligations under the notes and the indenture or PifCo provides such other security for the notes as is duly approved by a resolution of the noteholders in accordance with the indenture. In addition, PifCo will not allow any of its material subsidiaries to create or permit any lien, other than a PifCo permitted lien, on any of its assets to secure (i) any of its indebtedness, (ii) any of the material subsidiary’s indebtedness or (iii) the indebtedness of any other person, unless it contemporaneously creates or permits the lien to secure equally and ratably its obligations under the notes and the indenture or PifCo provides such other security for the notes as is duly approved by a resolution of the noteholders in accordance with the indenture.

     This covenant is subject to a number of important exceptions, including an exception that permits PifCo to grant liens in respect of indebtedness the principal amount of which, in the aggregate, together with all other liens not otherwise described in a specific exception, does not exceed 15% of PifCo’s consolidated total assets (as determined in accordance with U.S. GAAP or IFRS) at any time as at which PifCo’s balance sheet is prepared and published in accordance with applicable law.

     Limitation on Consolidation, Merger, Sale or Conveyance

     PifCo will not, in one or a series of transactions, consolidate or 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 (other than a direct or indirect subsidiary of Petrobras) or permit any person (other than a direct or indirect subsidiary of PifCo) to merge with or into it unless:

	•		either PifCo is the continuing entity or the person (the “successor company”) formed by the consolidation or into which PifCo is merged or that acquired or leased the property or assets of PifCo will assume (jointly and severally with PifCo unless PifCo will have ceased to exist as a result of that merger, consolidation or amalgamation), by a supplemental indenture (the form and substance of which will be previously approved by the trustee), all of PifCo’s obligations under the indenture and the notes;
	•		the successor company (jointly and severally with PifCo unless PifCo will have ceased to exist as part of the merger, consolidation or amalgamation) agrees to indemnify each holder against any tax, assessment or governmental charge thereafter imposed on the holder solely as a consequence of the consolidation, merger, conveyance, transfer or lease with respect to the payment of principal of, or interest, the notes;
	•		immediately after giving effect to the transaction, no event of default, and no default has occurred and is continuing;
	•		PifCo has delivered to the trustee an officers’ certificate and an opinion of counsel, each stating that the transaction, and each supplemental indenture relating to the transaction, comply with the terms of the indenture dated as of December 15, 2006, and that all conditions precedent provided for in the indenture and relating to the transaction have been complied with; and
	•		PifCo has delivered notice of any such transaction to the trustee.

     Notwithstanding anything to the contrary in the foregoing, so long as no default or event of default under the indenture or the notes will have occurred and be continuing at the time of the proposed transaction or would result from the transaction:

	•		PifCo may merge, amalgamate or consolidate with or into, or convey, transfer, lease or otherwise dispose of all or substantially all of its properties, assets or revenues to a direct or indirect subsidiary of PifCo or
	•		Petrobras in cases when PifCo is the surviving entity in the transaction and the transaction would not have a material adverse effect on PifCo and its subsidiaries taken as a whole, it being understood that if PifCo is not the surviving entity, PifCo will be required to comply with the requirements set forth in the previous paragraph; or
	•		any direct or indirect subsidiary of PifCo may merge or consolidate with or into, or convey, transfer, lease or otherwise dispose of assets to, any person (other than PifCo or any of its subsidiaries or affiliates) in cases when the transaction would not have a material adverse effect on PifCo and its subsidiaries taken as a whole; or
	•		any direct or indirect subsidiary of PifCo may merge or consolidate with or into, or convey, transfer, lease or otherwise dispose of assets to, any other direct or indirect subsidiary of PifCo or Petrobras; or
	•		any direct or indirect subsidiary of PifCo may liquidate or dissolve if PifCo determines in good faith that the liquidation or dissolution is in the best interests of Petrobras, and would not result in a material adverse effect on PifCo and its subsidiaries taken as a whole and if the liquidation or dissolution is part of a corporate reorganization of PifCo or Petrobras.

     PifCo may omit to comply with any term, provision or condition set forth in certain covenants applicable to the notes or any term, provision or condition of the indenture, if before the time for the compliance the holders of at least a majority in principal amount of the outstanding notes waive the compliance, but no waiver can operate except to the extent expressly waived, and, until a waiver becomes effective, PifCo’s obligations and the duties of the trustee in respect of any such term, provision or condition will remain in full force and effect.

     As used above, the following terms have the meanings set forth below:

     “indebtedness” means any obligation (whether present or future, actual or contingent and including any guaranty) for the payment or repayment of money that has been borrowed or raised (including money raised by acceptances and all leases which, under generally accepted accounting principles in the United States, would be a capital lease obligation).

     A “guaranty” means an obligation of a person to pay the indebtedness of another person including, without limitation:

	•		an obligation to pay or purchase such indebtedness;
	•		an obligation to lend money or to purchase or subscribe for shares or other securities or to purchase assets or services in order to provide funds for the payment of such indebtedness;
	•		an indemnity against the consequences of a default in the payment of such indebtedness; or
	•		any other agreement to be responsible for such indebtedness.

     A “lien” means any mortgage, pledge, lien, hypothecation, security interest or other charge or encumbrance on any property or asset including, without limitation, any equivalent created or arising under applicable law.

     A “PifCo permitted lien” means a:

     (a) lien arising by operation of law, such as merchants’, maritime or other similar liens arising in PifCo’s ordinary course of business or that of any subsidiary or lien in respect of taxes, assessments or other governmental charges that are not yet delinquent or that are being contested in good faith by appropriate proceedings;

     (b) lien arising from PifCo’s obligations under performance bonds or surety bonds and appeal bonds or similar obligations incurred in the ordinary course of business and consistent with PifCo’s past practice;

     (c) lien arising in the ordinary course of business in connection with indebtedness maturing not more than one year after the date on which that indebtedness was originally incurred and which is related to the financing of export, import or other trade transactions;

     (d) lien granted upon or with respect to any assets hereafter acquired by PifCo or any subsidiary to secure the acquisition costs of those assets or to secure indebtedness incurred solely for the purpose of financing the acquisition of those assets, including any lien existing at the time of the acquisition of those assets, so long as the maximum amount so secured does not exceed the aggregate acquisition costs of all such assets or the aggregate indebtedness incurred solely for the acquisition of those assets, as the case may be;

     (e) lien granted in connection with indebtedness of a wholly-owned subsidiary owing to PifCo or another wholly-owned subsidiary;

     (f) lien existing on any asset or on any stock of any subsidiary prior to the acquisition thereof by PifCo or any subsidiary, so long as the lien is not created in anticipation of that acquisition;

     (g) lien existing as of the date of the indenture;

     (h) lien resulting from the indenture or the guaranty, if any;

     (i) lien incurred in connection with the issuance of debt or similar securities of a type comparable to those already issued by PifCo, on amounts of cash or cash equivalents on deposit in any reserve or similar account to pay interest on those securities for a period of up to 24 months as required by any rating agency as a condition to the rating agency rating those securities as investment grade;

     (j) lien granted or incurred to secure any extension, renewal, refinancing, refunding or exchange (or successive extensions, renewals, refinancings, refundings or exchanges), in whole or in part, of or for any indebtedness secured by liens referred to in paragraphs (a) through (i) above (but not paragraph (d)), so long as the lien does not extend to any other property, the principal amount of the indebtedness secured by the lien is not increased, and in the case of paragraphs (a), (b), (c) and (f), the obligees meet the requirements of the applicable paragraph; and

     (k) lien in respect of indebtedness the principal amount of which in the aggregate, together with all other liens not otherwise qualifying as PifCo permitted liens pursuant to another part of this definition of PifCo permitted liens, does not exceed 15% of PifCo’s consolidated total assets (as determined in accordance with U.S. GAAP) at any date as at which PifCo’s balance sheet is prepared and published in accordance with applicable law.

     A “wholly-owned subsidiary” means, with respect to any corporate entity, any person of which 100% of the outstanding capital stock (other than qualifying shares, if any) having by its terms ordinary voting power (not dependent on the happening of a contingency) to elect the board of directors (or equivalent controlling governing body) of that person, is at the time owned or controlled directly or indirectly by that corporate entity, by one or more wholly-owned subsidiaries of that corporate entity or by that corporate entity and one or more wholly-owned subsidiaries.

Optional Redemption

     PifCo will not be permitted to redeem the notes before their stated maturity, except as set forth below. The notes will not be entitled to the benefit of any sinking fund—meaning that we will not deposit money on a regular basis into any separate account to repay your notes. In addition, you will not be entitled to require us to repurchase your notes from you before the stated maturity.

     Optional Redemption With “Make-Whole” Amount

     PifCo will have the right at our option to redeem any of the notes in whole or in part, at any time or from time to time prior to their maturity, on at least 30 days’ but not more than 60 days’ notice, at a redemption price equal to the greater of (1) 100% of the principal amount of such notes and (2) the sum of the present values of each remaining scheduled payment of principal and interest thereon (exclusive of interest accrued to the date of redemption) discounted to the redemption date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus            basis points (the “Make-Whole Amount”), plus in each case accrued interest on the principal amount of such notes to the date of redemption.

     “Treasury Rate” means, with respect to any redemption date, the rate per annum equal to the semiannual equivalent yield to maturity or interpolated maturity (on a day count basis) of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date.

     “Comparable Treasury Issue” means the United States Treasury security or securities selected by an Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term of the notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of a comparable maturity to the remaining term of such notes.

     “Independent Investment Banker” means one of the Reference Treasury Dealers appointed by us.

     “Comparable Treasury Price” means, with respect to any redemption date (1) the average of the Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest such Reference Treasury Dealer Quotation or (2) if the trustee obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations.

     “Reference Treasury Dealer” means each of HSBC Securities (USA) Inc. and J.P. Morgan Securities Inc. or, in each case, their affiliates, which are primary United States government securities dealers and two other leading primary United States government securities dealers in New York City reasonably designated by us in writing; provided, however, that if any of the foregoing shall cease to be a primary United States government securities dealer in New York City (a “Primary Treasury Dealer”), we will substitute therefor another Primary Treasury Dealer.

     “Reference Treasury Dealer Quotation” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the trustee by such Reference Treasury Dealer at 3:30 pm New York time on the third business day preceding such redemption date.

     On and after the redemption date, interest will cease to accrue on the notes or any portion of the notes called for redemption (unless we default in the payment of the redemption price and accrued interest). On or before the redemption date, we will deposit with the trustee money sufficient to pay the redemption price of and (unless the redemption date shall be an interest payment date) accrued interest to the redemption date on the notes to be redeemed on such date. If less than all of the notes are to be redeemed, the notes to be redeemed shall be selected by the trustee by such method as set forth in the indenture.

     Redemption for Taxation Reasons

     We have the option, subject to certain conditions, to redeem the notes in whole at their principal amount, plus accrued and unpaid interest, if any, to the relevant date of redemption, if and when, as a result of a change in, execution of, or amendment to, any laws or treaties or the official application or interpretation of any laws or treaties, we would be required to pay additional amounts related to the deduction of certain withholding taxes in respect of certain payments on the notes. See “Description of Debt Securities—Special Situations—Optional Tax Redemption” in the accompanying prospectus.

     The Optional Tax Redemption set forth in the accompanying prospectus shall apply with the reincorporation of PifCo being treated as the adoption of a successor entity. Such redemption shall not be available if the 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 in such new jurisdiction of incorporation that would result in the obligation to pay additional amounts.

     Further Issuances

     The indenture by its terms does not limit the aggregate principal amount of securities that may be issued under it and permits the issuance, from time to time, of additional notes (also referred to as add-on notes) of the same series as is being offered under this prospectus supplement. The ability to issue add-on notes is subject to several requirements, however, including that (i) no event of default under the indenture or event that with the passage of time or other action may become an event of default (such event being a “default”) will have occurred and then be continuing or will occur as a result of that additional issuance and (ii) the add-on notes will rank pari passu and have equivalent terms and benefits as the notes offered under this prospectus supplement except for the price to the public and the issue date. Any add-on notes will be part of the same series as the notes that PifCo is currently offering and the holders will vote on all matters in relation to the notes as a single series.

Covenant Defeasance

     Any restrictive covenants of the indenture may be defeased as described in the accompanying prospectus.

Conversion

     The notes will not be convertible into, or exchangeable for, any other securities.

Listing

     PifCo intends to apply to have the notes approved for listing on the NYSE.

Currency Rate Indemnity

     PifCo has agreed that, if a judgment or order made by any court for the payment of any amount in respect of any notes is expressed in a currency (the “judgment currency”) other than U.S. Dollars (the “denomination currency”), PifCo will indemnify the relevant holder against any deficiency arising from any variation in rates of exchange between the date as of which the denomination currency is notionally converted into the judgment currency for the purposes of the judgment or order and the date of actual payment. This indemnity will constitute a separate and independent obligation from PifCo’s other obligations under the indenture, will give rise to a separate and independent cause 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 order for a liquidated sum or sums in respect of amounts due in respect of the relevant note or under any judgment or order described above.

The Trustee and the Paying Agent

     The Bank of New York Mellon (formerly “The Bank of New York”), a New York banking corporation, is the trustee under the indenture and has been appointed by PifCo as registrar and paying agent with respect to the notes. The address of the trustee is 101 Barclay Street, 4E, New York, New York, 10286. PifCo will at all times maintain a paying agent in New York City until the notes are paid.

     Any corporation or association into which the trustee may be merged or converted or with which it may be consolidated, or any corporation or association resulting from any merger, conversion or consolidation to which the trustee shall be a party, or any corporation or association to which all or substantially all of the corporate trust business of the trustee may be sold or otherwise transferred, shall be the successor trustee hereunder without any further act.

CLEARANCE AND SETTLEMENT

Book-Entry Issuance

     Except under the limited circumstances described below, all notes will be book-entry notes. This means that the actual purchasers of the notes will not be entitled to have the notes registered in their names and will not be entitled to receive physical delivery of the notes in definitive (paper) form. Instead, upon issuance, all the notes will be represented by one or more fully registered global notes.

     Each global note will be deposited directly with The Depository Trust Company, a securities depositary, and will be registered in the name of DTC’s nominee. Global notes may also be deposited indirectly with Clearstream, Luxembourg and Euroclear, as indirect participants of DTC. For background information regarding DTC and Clearstream, Luxembourg and Euroclear, see "—Depository Trust Company” and “—Clearstream, Luxembourg and Euroclear” below. No global note representing book-entry notes may be transferred except as a whole by DTC to a nominee of DTC, or by a nominee of DTC to another nominee of DTC. Thus, DTC will be the only registered holder of the notes and will be considered the sole representative of the beneficial owners of the notes for purposes of the indenture. For an explanation of the situations in which a global note will terminate and interests in it will be exchanged for physical certificates representing the notes, see “Legal Ownership—Global Securities” in the accompanying prospectus.

     The registration of the global notes in the name of DTC’s nominee will not affect beneficial ownership and is performed merely to facilitate subsequent transfers. The book-entry system, which is also the system through which most publicly traded common stock is held in the United States, is used because it eliminates the need for physical movement of securities certificates. The laws of some jurisdictions, however, may require some purchasers to take physical delivery of their notes in definitive form. These laws may impair the ability of beneficial holders to transfer the notes.

     In this prospectus supplement, unless and until definitive (paper) notes are issued to the beneficial owners as described below, all references to “registered holders” of notes shall mean DTC. PifCo, Petrobras, the trustee and any paying agent, transfer agent or registrar may treat DTC as the absolute owner of the notes for all purposes.

     DTC participants that hold securities through DTC on behalf of investors will follow the settlement practices applicable to United States corporate debt obligations in DTC’s Same-Day Funds Settlement System. Securities will be credited to the securities custody accounts of these DTC participants against payment in the same-day funds, for payments in U.S. Dollars, on the settlement date.

Secondary Market Trading

     We understand that secondary market trading between DTC participants will occur in the ordinary way in accordance with DTC’s rules. Secondary market trading will be settled using procedures applicable to United States corporate debt obligations in DTC’s Same-Day Funds Settlement System. If payment is made in U.S. Dollars, settlement will be free of payment. If payment is made in other than U.S. Dollars, separate payment arrangements outside of the DTC system must be made between the DTC participants involved.

The Depository Trust Company

     The policies of DTC will govern payments, transfers, exchange and other matters relating to the beneficial

owner’s interest in the notes held by that owner. Neither the Trustee, Registrar, Paying Agent, Transfer Agent nor we have any responsibility for any aspect of the actions of DTC or any of their direct or indirect participants. Neither the Trustee, Registrar, Paying Agent, Transfer Agent nor we have any responsibility for any aspect of the records kept by DTC or any of their direct or indirect participants. In addition, neither the Trustee, Registrar, Paying Agent, Transfer Agent nor we supervise DTC in any way. DTC and their participants perform these clearance and settlement functions under agreements they have made with one another or with their customers. Investors should be aware that DTC and its participants are not obligated to perform these procedures and may modify them or discontinue them at any time.

     The description of the clearing systems in this section reflects our understanding of the rules and procedures of DTC as they are currently in effect. DTC could change its rules and procedures at any time.

     DTC has advised us as follows:

•

DTC is:

	•		a limited purpose trust company organized under the laws of the State of New York;
	•		a member of the Federal Reserve System;
	•		a “clearing corporation” within the meaning of the Uniform Commercial Code; and
	•		a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act.

	•		DTC was created to hold securities for its participants and to facilitate the clearance and settlement of securities transactions between participants through electronic book-entry changes to accounts of its participants. This eliminates the need for physical movement of certificates.
	•		Participants in DTC include securities brokers and dealers, banks, trust companies and clearing corporations and may include certain other organizations. DTC is partially owned by some of these participants or their representatives.
	•		Indirect access to the DTC system is also available to banks, brokers, dealer and trust companies that have relationships with participants.
	•		The rules applicable to DTC and DTC participants are on file with the SEC.

Clearstream, Luxembourg and Euroclear

     Clearstream, Luxembourg has advised that: it is a duly licensed bank organized as a société anonyme incorporated under the laws of Luxembourg and is subject to regulation by the Luxembourg Commission for the supervision of the financial sector (Commission de surveillance du secteur financier); it holds securities for its customers and facilitates the clearance and settlement of securities transactions among them, and does so through electronic book-entry transfers between the accounts of its customers, thereby eliminating the need for physical movement of certificates; it provides other services to its customers, including safekeeping, administration, clearance and settlement of internationally traded securities and lending and borrowing of securities; it interfaces with the domestic markets in over 30 countries through established depositary and custodial relationships; its customers include worldwide securities brokers and dealers, banks, trust companies and clearing corporations and may include certain other professional financial intermediaries; its U.S. customers are limited to securities brokers and dealers and banks; and indirect access to the Clearstream, Luxembourg system is also available to others that clear through Clearstream, Luxembourg customers or that have custodial relationships with its customers, such as banks, brokers, dealers and trust companies.

     Euroclear has advised that: it is incorporated under the laws of Belgium as a bank and is subject to regulation by the Belgian Banking and Finance Commission (Commission Bancaire et Financière) and the National Bank of

Belgium (Banque Nationale de Belgique); it holds securities for its participants and facilitates the clearance and settlement of securities transactions among them; it does so through simultaneous electronic book-entry delivery against payments, thereby eliminating the need for physical movement of certificates; it provides other services to its participants, including credit, custody, lending and borrowing of securities and tri-party collateral management; it interfaces with the domestic markets of several countries; its customers include banks, including central banks, securities brokers and dealers, banks, trust companies and clearing corporations and certain other professional financial intermediaries; indirect access to the Euroclear system is also available to others that clear through Euroclear customers or that have custodial relationships with Euroclear customers; and all securities in Euroclear are held on a fungible basis, which means that specific certificates are not matched to specific securities clearance accounts.

     Clearance and Settlement Procedures

     We understand that investors that hold their notes through Clearstream, Luxembourg or Euroclear accounts will follow the settlement procedures that are applicable to securities in registered form. Notes will be credited to the securities custody accounts of Clearstream, Luxembourg and Euroclear participants on the business day following the settlement date for value on the settlement date. They will be credited either free of payment or against payment for value on the settlement date.

     We understand that secondary market trading between Clearstream, Luxembourg and/or Euroclear participants will occur in the ordinary way following the applicable rules and operating procedures of Clearstream, Luxembourg and Euroclear. Secondary market trading will be settled using procedures applicable to securities in registered form.

     You should be aware that investors will only be able to make and receive deliveries, payments and other communications involving the notes through Clearstream, Luxembourg and Euroclear on business days. Those systems may not be open for business on days when banks, brokers and other institutions are open for business in the United States or Brazil.

     In addition, because of time-zone differences, there may be problems with completing transactions involving Clearstream, Luxembourg and Euroclear on the same business day as in the United States or Brazil. U.S. and Brazilian investors who wish to transfer their interests in the notes, or to make or receive a payment or delivery of the notes on a particular day may find that the transactions will not be performed until the next business day in Luxembourg or Brussels, depending on whether Clearstream, Luxembourg or Euroclear is used.

     Clearstream, Luxembourg or Euroclear will credit payments to the cash accounts of participants in Clearstream, Luxembourg or Euroclear in accordance with the relevant systemic rules and procedures, to the extent received by its depositary. Clearstream, Luxembourg or the Euroclear, as the case may be, will take any other action permitted to be taken by a registered holder under the indenture on behalf of a Clearstream, Luxembourg or Euroclear participant only in accordance with its relevant rules and procedures.

     Clearstream, Luxembourg and Euroclear have agreed to the foregoing procedures in order to facilitate transfers of the notes among participants of Clearstream, Luxembourg and Euroclear. However, they are under no obligation to perform or continue to perform those procedures, and they may discontinue those procedures at any time.

DESCRIPTION OF THE GUARANTY

General

     In connection with the execution and delivery of the second supplemental indenture and the notes offered by this prospectus supplement, Petrobras will guarantee the notes for the benefit of the holders.

     The guaranty will provide that Petrobras will unconditionally and irrevocably guarantee the notes on the terms and conditions described below.

     The following summary describes the material provisions of the guaranty. You should read the more detailed provisions of the guaranty, including the defined terms, for provisions that may be important to you. This summary is subject to, and qualified in its entirety by reference to, the provisions of the guaranty.

     Despite the Brazilian government’s ownership interest in Petrobras, the Brazilian government is not responsible in any manner for PifCo’s obligations under the notes or Petrobras’ obligations under the guaranty. Petrobras’ obligations under the guaranty are no less binding or enforceable than its obligations generally under the prior standby purchase agreements.

     Due to a change in Brazilian law, in addition to the standby purchase agreements used in prior issuances by PifCo, Petrobras is also allowed to render guaranties in connection with the notes. Petrobras intends to use guaranties in future issuances of notes. The obligations of Petrobras under the guaranty are similar to its obligations under the standby purchase agreements used in prior issuances.

Ranking

     The obligations of Petrobras under the guaranty will constitute general unsecured obligations of Petrobras which at all times will rank pari passu with all other senior unsecured obligations of Petrobras that are not, by their terms, expressly subordinated in right of payment to the obligations of Petrobras under the guaranty.

Nature of Obligation

     Petrobras will unconditionally and irrevocably guarantee the full and punctual payment when due, whether at the maturity date of the notes, or earlier or later by acceleration or otherwise, of all of PifCo’s obligations now or hereafter existing under the indenture and the notes, whether for principal, interest, make-whole premium, fees, indemnities, costs, expenses or otherwise (such obligations being referred to as the “guaranteed obligations”).

     The obligation of Petrobras to pay amounts in respect of the guaranteed obligations will be absolute and unconditional upon failure of PifCo to make, at the maturity date of the notes or earlier upon any acceleration of the notes in accordance with the terms of the indenture, any payment in respect of principal, interest or other amounts due under the indenture and the notes on the date any such payment is due. If PifCo fails to make payments to the trustee in respect of the guaranteed obligations, Petrobras will, upon notice from the trustee, immediately pay to the trustee such amount of the guaranteed obligations payable under the indenture and the notes. All amounts payable by Petrobras under the guaranty will be payable in U.S. Dollars and in immediately available funds to the trustee. Petrobras will not be relieved of its obligations under the guaranty unless and until the trustee receives all amounts required to be paid by Petrobras under such guaranty (and any related event of default under the indenture has been cured), including payment of the total non-payment overdue interest.

Events of Default

     There are no events of default under the guaranty. The second supplemental indenture, however, contain events of default relating to Petrobras that may trigger an event of default and acceleration of the notes. See “Description of Debt Securities—Default and Related Matters—Events of Default” in the accompanying prospectus. Upon any such acceleration (including any acceleration arising out of the insolvency or similar events relating to Petrobras), if PifCo fails to pay all amounts then due under the notes and the indenture, Petrobras will be obligated to make such

payments pursuant to the guaranty.

Covenants

     For so long as any of the notes are outstanding and Petrobras has obligations under the guaranty, Petrobras will, and will cause each of its subsidiaries to, comply with the terms of the covenants set forth below:

     Performance Obligations under the Guaranty and Indenture

     Petrobras will pay all amounts owed by it and comply with all its other obligations under the terms of the guaranty and the indenture in accordance with the terms of those agreements.

     Maintenance of Corporate Existence

     Petrobras will maintain in effect its corporate existence and all necessary registrations and take all actions 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. However, this covenant will not require Petrobras to maintain any such right, privilege, title to property or franchise if the failure to do so does not, and will not, have a material adverse effect on Petrobras taken as a whole or have a materially adverse effect on the rights of the holders of the notes.

     Maintenance of Office or Agency

     So long as any note is outstanding, Petrobras will 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 guaranty may be served. Initially this office will be located at Petrobras’ existing principal U.S. office at 570 Lexington Avenue, 43rd Floor, New York, New York 10022-6837. Petrobras will agree not to change the designation of their office without prior written notice to the trustee and designation of a replacement office in the same general location.

     Ranking

     Petrobras will ensure at all times that its obligations under the guaranty will be its general senior unsecured and unsubordinated obligations and will rank pari passu, without any preferences among themselves, with all other present and future senior unsecured and unsubordinated obligations 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 guaranty.

     Notice of Certain Events

     Petrobras will give written notice to the trustee, as soon as is practicable and in any event within ten calendar days after Petrobras becomes aware, or should reasonably become aware, of the occurrence of any event of default or a default under the indenture, accompanied by a certificate of Petrobras setting forth the details of that event of default or default and stating what action Petrobras proposes to take with respect to it.

     Provision of Financial Statements and Reports

     Petrobras will provide to the trustee, in English or accompanied by a certified English translation thereof, (i) within 90 calendar days after the end of each fiscal quarter (other than the fourth quarter), its unaudited and consolidated balance sheet and statement of income calculated in accordance with U.S. GAAP or IFRS, if Petrobras adopts IFRS as its primary reporting or accounting standard in reports filed with the SEC, (ii) within 120 calendar days after the end of each fiscal year, its audited and consolidated balance sheet and statement of income calculated in accordance with U.S. GAAP or IFRS and (iii) such other financial data as the trustee may reasonably request.

     Petrobras will provide, together with each of the financial statements delivered as described in the preceding paragraph, an officers’ certificate stating that a review of Petrobras’ and PifCo’s activities has been made during the

period covered by such financial statements with a view to determining whether Petrobras and PifCo have kept, observed, performed and fulfilled their covenants and agreements under the guaranty and the indenture, as applicable, and that no event of default has occurred during such period.

     In addition, whether or not Petrobras is required to file reports with the SEC, Petrobras will file with the SEC and deliver to the trustee (for redelivery to all holders of the notes, upon written request) all reports and other information it would be required to file with the SEC under the Exchange Act if it were subject to those regulations. If the SEC does not permit the filing described above, Petrobras will provide annual and interim reports and other information to the trustee within the same time periods that would be applicable if Petrobras were required and permitted to file these reports with the SEC.

     Upon written request of any holder or The Depository Trust Company, the reports and other information described above shall be delivered to DTC at 55 Water Street, 25th Floor, New York, NY 10041, Attention: Proxy Department, or such other address as DTC may provide to the trustee in writing.

     Delivery of these reports, information and documents to the trustee is for informational purposes only and the trustee’s receipt of any of those shall not constitute constructive notice of any information contained in them or determinable from information contained therein, including Petrobras’ compliance with any of its covenants in the guaranty (as to which the trustee is entitled to rely exclusively on officer’s certificates).

     Negative Pledge

     So long as any note remains outstanding, Petrobras will not create or permit any lien, other than a Petrobras permitted lien, on any of its assets to secure (i) any of its indebtedness or (ii) the indebtedness of any other person, unless Petrobras contemporaneously creates or permits the lien to secure equally and ratably its obligations under the guaranty or Petrobras provides other security for its obligations under the guaranties as is duly approved by a resolution of the noteholders in accordance with the indenture. In addition, Petrobras will not allow any of its material subsidiaries to create or permit any lien, other than a Petrobras permitted lien, on any of Petrobras’ assets to secure (i) any of its indebtedness, (ii) any of the material subsidiary’s indebtedness or (iii) the indebtedness of any other person, unless Petrobras contemporaneously creates or permits the lien to secure equally and ratably Petrobras’ obligations under the guaranty or Petrobras provides such other security for its obligations under the guaranty as is duly approved by a resolution of the noteholders in accordance with the indenture.

     Limitation on Consolidation, Merger, Sale or Conveyance

     Petrobras will not, in one or a series of transactions, consolidate or 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 (other than a direct or indirect subsidiary of Petrobras) or permit any person (other than a direct or indirect subsidiary of Petrobras) to merge with or into it unless:

•

either Petrobras is the continuing entity or the person (the “successor company”) formed by such consolidation or into which Petrobras is merged or that acquired or leased such property or assets of Petrobras

will assume (jointly and severally with Petrobras unless Petrobras will have ceased to exist as a result of such merger, consolidation or amalgamation), by an amendment to the applicable guaranty (the form and substance of which will be previously approved by the trustee), all of Petrobras’ obligations under such guaranty;

	•		the successor company (jointly and severally with Petrobras unless Petrobras will have ceased to exist as part of such merger, consolidation or amalgamation) agrees to indemnify each holder against any tax, assessment or governmental charge thereafter imposed on such holder solely as a consequence of such consolidation, merger, conveyance, transfer or lease with respect to the payment of principal of, or interest on, the notes;
	•		immediately after giving effect to the transaction, no event of default, and no default has occurred and is continuing;
	•		Petrobras has delivered to the trustee an officers’ certificate and an opinion of counsel, each stating that the transaction and the amendment to the guaranty comply with the terms of the guaranty and that all conditions precedent provided for in such guaranty and relating to such transaction have been complied with; and
	•		Petrobras has delivered notice of any such transaction to the trustee.

     Notwithstanding anything to the contrary in the foregoing, so long as no default or event of default under the indenture or the notes, as applicable, has occurred and is continuing at the time of such proposed transaction or would result therefrom and Petrobras has delivered notice of any such transaction to the trustee:

•

Petrobras may merge, amalgamate or consolidate with or into, or convey, transfer, lease or otherwise dispose of all or substantially all of its properties, assets or revenues to a direct or indirect subsidiary of Petrobras in cases when Petrobras is the surviving entity in such transaction and such transaction would not have a material adverse effect on Petrobras and its subsidiaries taken as whole, it being understood that if Petrobras is not the surviving entity, Petrobras will be required to comply with the requirements set forth in the previous paragraph.

Amendments

     The guaranty may only be amended or waived in accordance with their terms pursuant to a written document which has been duly executed and delivered by Petrobras and the trustee, acting on behalf of the noteholders. Because the guaranty forms part of the indenture, it may be amended by Petrobras and the trustee, in some cases without the consent of the noteholders. See “Description of Debt Securities—Special Situations—Modification and Waiver” in the accompanying prospectus.

     Except as contemplated above, the indenture will provide that the trustee may execute and deliver any other amendment to the guaranty or grant any waiver thereof only with the consent of the holders of a majority in aggregate principal amount of the notes then outstanding.

Governing Law

     The guaranty will be governed by the laws of the State of New York.

Jurisdiction

     Petrobras has consented to the non-exclusive jurisdiction of any court of the State of New York or any U.S. federal court sitting in the Borough of Manhattan, The City of New York, New York, United States and any appellate court from any thereof. Service of process in any action or proceeding brought in such New York State federal court sitting in New York City may be served upon Petrobras at Petrobras’ New York office. The guaranty provide that if Petrobras no longer maintains an office in New York City, then it will appoint a replacement process agent within New York City as its authorized agent upon which process may be served in any action or proceeding.

Waiver of Immunities

     To the extent that Petrobras may in any jurisdiction claim for itself or its assets immunity from a suit, execution, attachment, whether in aid of execution, before judgment or otherwise, or other legal process in connection with the guaranty (or any document delivered pursuant thereto) and to the extent that in any jurisdiction there may be immunity attributed to Petrobras, PifCo or their assets, whether or not claimed, Petrobras has irrevocably agreed with the trustee, for the benefit of the holders, not to claim, and to irrevocably waive, the immunity to the full extent permitted by law.

Currency Rate Indemnity

     Petrobras has agreed that, if a judgment or order made by any court for the payment of any amount in respect of any of its obligations under the guaranty is expressed in a currency (the “judgment currency”) other than U.S. Dollars (the “denomination currency”), Petrobras will indemnify the trustee, on behalf of the noteholders, against any deficiency arising from any variation in rates of exchange between the date as of which the denomination currency is notionally converted into the judgment currency for the purposes of the judgment or order and the date of actual payment. This indemnity will constitute a separate and independent obligation from Petrobras’ other obligations under the guaranty, will give rise to a separate and independent cause of action, will apply irrespective of any indulgence granted from time to time and will continue in full force and effect.

PLAN OF DISTRIBUTION

     Under the terms and subject to the conditions contained in the underwriting agreement dated February  , 2009, by and among PifCo, Petrobras, HSBC Securities (USA) Inc., with offices at 452 Fifth Avenue, New York, New York 10018, J.P.

     The underwriting agreement provides that the obligation of the underwriters to pay for and accept delivery of the notes is subject to, among other conditions, the delivery of certain legal opinions by its counsel. The underwriters are obligated to take and pay for all of the notes offered by this prospectus supplement if any notes are taken. The notes will initially be offered at the price indicated on the cover page of this prospectus supplement. After the initial offering of the notes, the offering price and other selling terms may from time to time be varied by the underwriters.

     The underwriting agreement provides that PifCo and Petrobras will indemnify the underwriters against certain liabilities, including liabilities under the Securities Act, and will contribute to payments the underwriters may be required to make in respect of the underwriting agreement.

     PifCo has been advised by the underwriters that the underwriters intend to make a market in the notes as permitted by applicable laws and regulations. The underwriters are not obligated, however, to make a market in the notes and any such market-making may be discontinued at any time at the sole discretion of the underwriters. In addition, such market-making activity will be subject to the limits imposed by the Exchange Act. Accordingly, no assurance can be given as to the liquidity of, or the development or continuation of trading markets for, the notes.

     In connection with this offering, certain persons participating in this offering may engage in transactions that stabilize, maintain or otherwise affect the price of the notes. Specifically, the underwriters may bid for and purchase notes in the open market to stabilize the price of the notes. The underwriters may also over-allot this offering, creating a short position, and may bid for and purchase notes in the open market to cover the short position. In addition, the underwriters may bid for and purchase the notes in market-making transactions and impose penalty bids. These activities may stabilize and maintain the market price of the notes above market levels that may otherwise prevail. The underwriters are not required to engage in these activities, and may end these activities at any time.

     The underwriters have from time to time in the past provided, and may in the future provide, investment banking, financial advisory and other services to Petrobras, PifCo and their affiliates for which the underwriters have received or expect to receive customary fees. Affiliates of some of the underwriters may be lenders under certain bridge loans entered into by Petrobras to raise an amount of up to U.S.$7 billion in the near future.

     By virtue of placing an order to purchase the notes, each prospective Canadian investor who purchases the notes will be deemed to have represented to PifCo and the dealer with whom the order was placed that such purchaser (i) is an “accredited investor” as defined in section 1.1 of National Instrument 45-106 Prospectus and Registration Exemptions (“NI 45-106”); (ii) where required by law, such purchaser is purchasing as principal; (iii) has not been created or used solely to purchase or hold securities as an accredited investor; (iv) has reviewed and acknowledges the terms referred to above under “Resale Restrictions”; and (v) in the case of an investor resident in Ontario, that such investor, or any ultimate investor for which such investor is acting as agent (1) is an “accredited investor”, other than an individual, as defined in section 1.1 of NI 45-106 and is purchasing the notes from a dealer registered in the province of Ontario as an international dealer within the meaning of section 98 of the Regulation to the Securities Act (Ontario) or (2) is an “accredited investor”, including an individual as defined in section 1.1 of NI 45-106 and is purchasing the notes from a registered investment dealer or limited market dealer registered in Ontario within the meaning of section 98 of the Regulation to the Securities Act (Ontario).

     In addition, each purchaser resident in Ontario, by placing an order to purchase the notes will be deemed to have represented to PifCo and the dealer with whom such order was placed, that such purchaser: (a) has been notified (i) that PifCo may be required to provide information (‘personal information’) pertaining to the purchaser as required to be disclosed in Schedule I of Form 45-106F1 (including its name, address, telephone number and the number and value of the notes purchased), which is required to be filed by PifCo under NI 45-106; (ii) that such personal information will be delivered to the OSC in accordance with NI 45-106; (iii) that such personal information is being collected indirectly by the OSC under the authority granted to it under the securities legislation of Ontario; (iv) that such personal information is being collected for the purposes of the administration and enforcement of the securities legislation of Ontario; and (v) that the public official in Ontario who can answer questions about the OSC’s indirect collection of such personal information is the Administrative Assistant to the Director of Corporate Finance at the OSC, Suite 1903, Box 55, 20 Queen Street West, Toronto, Ontario M5H 3S8, Telephone: (416) 593-8086; and (b) by purchasing the notes, such purchaser has authorized the indirect collection of the personal information by the OSC. Further, the purchaser acknowledges that its name, address, telephone number and other specified information, including the number of notes that it has purchased and the aggregate purchase price to the purchaser, may be disclosed to other Canadian securities regulatory authorities and may become available to the public in accordance with the requirements of applicable laws. By placing an order to purchase the notes the purchaser consents to the disclosure of such information.

     Prospective Canadian investors should consult with their own legal and tax advisers with respect to the tax consequences of an investment in the note in their particular circumstances and with respect to the eligibility of the notes for investment by such prospective investor under relevant Canadian legislation and regulations.

     Statutory Right of Action

     Securities legislation in certain Canadian provinces provides purchasers of securities offered under the prospectus supplement and accompanying prospectus (“Offering Documents”) with certain rights of action if the Offering Documents, together with any amendment hereto, contains a misrepresentation. The following is a description of these rights.

     For these purposes a “misrepresentation” means an untrue statement of a material fact or an omission to state a material fact that is necessary in order to make any statement not misleading in light of the circumstances in which it was made.

     Ontario

     Section 130.1 of the Securities Act (Ontario) provides that if the Offering Documents, together with any amendment thereto, contains a misrepresentation, a prospective investor in the Province of Ontario who has purchased a security offered by the Offering Documents during the period of its distribution shall have, without regard to whether such prospective investor relied upon the misrepresentation, a right of action for damages against PifCo or, at the election of the investor, a right of rescission against PifCo (in which case such investor shall cease to have a right of action for damages against PifCo), provided that:

     (a) no action may be commenced to enforce a right of action: (i) for rescission more than 180 days after the date of the purchase; and (ii) for damages later than the earlier of: (A) 180 days after the investor first had knowledge of the facts giving rise to the cause of action; and (B) three years after the date of purchase;

     (b) PifCo will not be liable if it proves that the investor purchased the security with knowledge of the misrepresentation;

     (c) in an action for damages, PifCo will not be liable for all or any portion of such damages that it proves do not represent the depreciation in value of the security as a result of the misrepresentation;

     (d) in no case shall the amount recoverable exceed the price at which the securities were offered; and

     (e) this right of action is in addition to and without derogation from any other right the investor may have at law.

     The foregoing rights do not apply if the investor is: (a) a Canadian financial institution (as defined in NI 45-106) or a Schedule III bank; (b) the Business Development Bank of Canada incorporated under the Business Development Bank of Canada Act (Canada); or (c) a subsidiary of any person referred to in paragraphs (a) and (b), if the person owns all of the voting securities of the subsidiary, except the voting securities required by law to be owned by directors of that subsidiary.

     The foregoing summary is subject to the express provisions of the Securities Act (Ontario) and the rules, regulations and other instruments thereunder, and reference is made to the complete text of such provisions contained therein. Such provisions may contain limitations and statutory defenses on which PifCo may rely.

Enforcement of Legal Rights

     All of PifCo’s directors and officers as well as the experts named herein may be located outside of Canada and, as a result, it may not be possible for Canadian purchasers to effect service of process within Canada upon PifCo or those persons. All or a substantial portion of PifCo’s assets and the assets of those persons may be located outside

of Canada and, as a result, it may not be possible to satisfy a judgment against PifCo or those persons in Canada or to enforce a judgment obtained in Canadian courts against PifCo or those persons outside of Canada.

Forward Looking Information

     These Offering Documents may contain “forward looking information” (“FLI”) as such term is defined in section 1.1 of the Securities Act (Ontario), FLI is disclosure regarding possible events, conditions or results of operations that is based on assumptions about future economic conditions and courses of action and includes future oriented financial information (“FOFI”) with respect to prospective results of operations, financial position or cash flows that is presented either as a forecast or a projection. “FOFI” is FLI about prospective results of operations, financial position or cash flows, based on assumptions about future economic conditions and courses of action, and presented in the format of a historical balance sheet, income statement or cash flow statement. Similarly, a “financial outlook” is FLI about prospective results of operations, financial position or cash flows that is based on assumptions about future economic conditions and courses of action that is not presented in the format of historical balance sheet, income statement or cash flow statement. Actual results may vary from the FLI contained in the Offering Documents as such information is subject to a variety of risks, uncertainties and other factors that could cause actual results to differ materially from expectations. Material risk factors that could affect actual results are identified under the heading “Risk Factors”. Investors are also cautioned that FLI is based on a number of factors and assumptions, including current plans, estimates opinions and analysis made in light of its experience, current conditions, and expectations of future developments, as well as other relevant factors.

     This offering is being made by a non-Canadian issuer using disclosure documents prepared in accordance with non-Canadian securities laws. Prospective purchasers should be aware that these requirements may differ significantly from those in Ontario. The FLI included or incorporated by reference herein may not be accompanied by the disclosure and explanations that would be required of a Canadian issuer under Ontario securities law.

     Canadian investors should not rely on any FLI that may be contained within these Offering Documents as such information is subject to a variety of risks, uncertainties and other factors that could cause actual results to differ materially from expectations. Upon receipt of these Offering Documents, each Canadian investor will be deemed to have acknowledged and agreed that any FLI included herein should not be considered material for the purposes of and may not have been prepared and/or presented consistent with National Instrument 51-102 Continues Disclosure Requirements (“NI 51-102”) and that the investor will not receive any additional information regarding such FLI during any period that PifCo is not a “reporting issuer” in any province or territory in Canada, other than as required under applicable securities laws in the province of Ontario.

European Economic Area

     In relation to each Member State that has implemented the Prospectus Directive (each, a “Relevant Member State”) an offer to the public of the notes which are the subject of the offering contemplated by this prospectus may not be made in that Relevant Member State except that an offer to the public in that Relevant Member State of any notes may be made at any time under the following exemptions under the Prospectus Directive, if they have been implemented in that Relevant Member State:

	•		to legal entities which are authorized or regulated to operate in the financial markets or, if not so authorized or regulated, whose corporate purpose is solely to invest in securities;
	•		to any legal entity which has two or more of (1) an average of at least 250 employees during the last financial year; (2) a total balance sheet of more than €43,000,000 and (3) an annual net turnover of more than €50,000,000, as shown in its last annual or consolidated accounts;

•

provided that no such offer of notes shall result in a requirement for the publication by PifCo or any underwriter of a prospectus pursuant to Article 3 of the Prospectus Directive.

     For the purposes of this provision, the expression an “offer to the public” in relation to any notes in any Relevant Member State means the communication in any form and by any means of sufficient information on the terms of the offer and any notes to be offered so as to enable an investor to decide to purchase any notes, as the same may be varied in that Member State by any measure implementing the Prospectus Directive in that Member State.

United Kingdom

     The underwriters have represented and agreed that: (i) they have only communicated or caused to be communicated and will only communicate or cause to be communicated an invitation or inducement to engage in investment activity (within the meaning of Section 21 of the UK Financial Services and Markets Act 2000 (the “FSMA”) received by them in connection with the issue or sale of any notes in circumstances in which Section 21(1) of the FSMA does not apply to PifCo and (ii) they have complied and will comply with all applicable provisions of the FSMA with respect to anything done by them in relation to the notes in, from or otherwise involving the United Kingdom.

     The notes are offered for sale in the United States and other jurisdictions where it is legal to make these offers. The distribution of this prospectus supplement and the accompanying prospectus, and the offering of the notes in certain jurisdictions may be restricted by law. Persons into whose possession this prospectus supplement and the accompanying prospectus come and investors in the notes should inform themselves about and observe any of these restrictions. This prospectus supplement and the accompanying prospectus do not constitute, and may not be used in connection with, an offer or solicitation by anyone in any jurisdiction in which such offer or solicitation is not authorized, or in which the person making such offer or solicitation is not qualified to do so, or to any person to whom it is unlawful to make such offer or solicitation.

     The underwriters have agreed that they have not offered, sold or delivered, and they will not offer, sell or deliver any of the notes, directly or indirectly, or distribute this prospectus supplement, the accompanying prospectus or any other offering material relating to the notes, in or from any jurisdiction except under circumstances that will, to the best knowledge and belief of the underwriters, after reasonable investigation, result in compliance with the applicable laws and regulations of such jurisdiction and which will not impose any obligations on PifCo except as set forth in the underwriting agreement.

     Neither PifCo nor the underwriters have represented that the notes may be lawfully sold in compliance with any applicable registration or other requirements in any jurisdiction, or pursuant to an exemption, or assumes any responsibility for facilitating these sales.

     The expenses of the offering, excluding the underwriting discount, are estimated to be U.S.$ and will be borne by PifCo.

     The underwriters propose to offer the notes initially at the public offering price set forth on the cover page of this prospectus supplement and to dealers at that price less a selling concession not in excess of      % of the principal amount of the notes. After the initial public offering of the notes, the public offering price and concession and discount to dealers may be changed.

     In compliance with FINRA guidelines, the maximum compensation to the underwriters or agents in connection with the sale of the notes pursuant to this prospectus supplement and the accompanying prospectus will not exceed 8% of the aggregate total offering price to the public of the notes as set forth on the cover page of this prospectus supplement; however, it is anticipated that the maximum compensation paid will be significantly less than 8%.

TAXATION

     There currently are no income tax treaties between Brazil and the United States. Although the tax authorities of Brazil and the United States have had recent discussions that may culminate in such a treaty, we cannot assure you as to whether or when a treaty will enter into force or how it will affect holders of the notes.

U.S. Federal Income Tax Considerations

     TO ENSURE COMPLIANCE WITH U.S. TREASURY DEPARTMENT CIRCULAR 230, HOLDERS ARE HEREBY NOTIFIED THAT: (A) ANY DISCUSSION OF U.S. FEDERAL TAX ISSUES IN THIS PROSPECTUS SUPPLEMENT IS NOT INTENDED OR WRITTEN TO BE RELIED UPON, AND CANNOT BE RELIED UPON, BY HOLDERS FOR THE PURPOSE OF AVOIDING PENALTIES THAT MAY BE IMPOSED ON HOLDERS UNDER THE INTERNAL REVENUE CODE OF 1986, AS AMENDED (THE “CODE”); (B) SUCH DISCUSSION IS INCLUDED HEREIN BY THE ISSUER IN CONNECTION WITH THE PROMOTION OR MARKETING (WITHIN THE MEANING OF CIRCULAR 230) BY THE ISSUER OF THE TRANSACTIONS OR MATTERS ADDRESSED HEREIN; AND (C) HOLDERS SHOULD SEEK ADVICE BASED ON THEIR PARTICULAR CIRCUMSTANCES FROM AN INDEPENDENT TAX ADVISOR.

     The following is a summary of certain U.S. federal income tax considerations that may be relevant to a beneficial owner of a note that is, for U.S. federal income tax purposes, a citizen or resident of the United States, a domestic corporation or an entity otherwise subject to U.S. federal income taxation on a net income basis in respect of the note (a “U.S. Holder”). This summary addresses only U.S. Holders that purchase notes at their issue price as part of the initial offering, and that hold such notes as capital assets. The summary does not address tax considerations applicable to investors that may be subject to special tax rules, such as banks, tax-exempt entities, insurance companies, dealers in securities or currencies, traders in securities electing to mark to market, persons that will hold notes as a position in a “straddle” or conversion transaction, or as part of a “synthetic security” or other integrated financial transaction or persons that have a “functional currency” other than the U.S. Dollar. A “Non-U.S. Holder” is a beneficial owner of the notes (other than a partnership or other entity treated as a partnership for U.S. federal income tax purposes) that is not a U.S. Holder.

     If a partnership (or other entity treated as a partnership for U.S. federal income tax purposes) holds the notes, then the tax treatment of a partner in such partnership generally will depend upon the status of the partner and the activities of the partnership. Such a partner or partnership should consult its own tax advisor as to the tax consequences of acquiring, owning and disposing of the notes.

     This summary is based on the Code, existing, proposed and temporary U.S. Treasury Regulations and judicial and administrative interpretations thereof, in each case as in effect and available on the date hereof. All of the foregoing are subject to change (possibly with retroactive effect) or to differing interpretations, which could affect the U.S. federal income tax consequences described herein.

     INVESTORS SHOULD CONSULT THEIR OWN TAX ADVISORS REGARDING THE U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE ACQUISITION, OWNERSHIP AND DISPOSITION OF THE NOTES, INCLUDING THE APPLICATION TO THEIR PARTICULAR CIRCUMSTANCES OF THE U.S. FEDERAL INCOME TAX CONSIDERATIONS DISCUSSED BELOW, AS WELL AS THE APPLICATION OF U.S. FEDERAL ESTATE, GIFT AND ALTERNATIVE MINIMUM TAX LAWS, U.S. STATE AND LOCAL TAX LAWS AND FOREIGN TAX LAWS.

     Payments of Interest and Additional Amounts

     Payments of interest on a note (which may include additional amounts) generally will be taxable to a U.S. Holder as ordinary interest income when such interest is accrued or received, in accordance with the U.S. Holder’s regular method of accounting for U.S. federal income tax purposes. Interest income in respect of the notes generally will constitute foreign-source income for purposes of computing the foreign tax credit allowable under the U.S. federal income tax laws. The limitation on foreign income taxes eligible for credit is calculated separately with

respect to specific classes of income. Such income generally will constitute “passive category income” for foreign tax credit purposes. The calculation and availability of foreign tax credits and, in the case of a U.S. Holder that elects to deduct foreign income taxes, the availability of such deduction involves the application of complex rules that depend on a U.S. Holder’s particular circumstances. In addition, foreign tax credits generally will not be allowed for certain short-term or hedged positions in the notes.

     U.S. Holders should consult their own tax advisors regarding the availability of foreign tax credits or deductions in respect of foreign taxes and the treatment of additional amounts.

     A Non-U.S. Holder generally will not be subject to U.S. federal income or withholding tax on interest income earned in respect of notes unless such income is effectively connected with the conduct by the Non-U.S. Holder of a trade or business in the United States. Non-U.S. Holders should consult their own tax advisors in the event interest income with respect to the notes is effectively connected with their trade or business in the United States.

     Sale or Disposition of Notes

     A U.S. Holder generally will recognize capital gain or loss upon the sale, exchange, retirement or other taxable disposition of a note in an amount equal to the difference between the amount realized upon such disposition (other than amounts attributable to accrued but unpaid interest, which will be taxed as ordinary income) and such U.S. Holder’s tax basis in the note. Gain or loss realized by a U.S. Holder on the disposition of a note generally will be long-term capital gain or loss if, at the time of the disposition, the note has been held for more than one year. The net amount of long-term capital gain realized by an individual U.S. Holder generally is subject to tax at a reduced rate, which rates currently are scheduled to increase on January 1, 2011. The deductibility of capital losses is subject to limitations. Capital gain or loss recognized by a U.S. Holder generally will be U.S.-source gain or loss. Consequently, if any such gain is subject to foreign withholding tax, a U.S. Holder may not be able to credit the tax against its U.S. federal tax liability unless such credit can be applied (subject to applicable limitation) against tax due on other income treated as derived from foreign sources. U.S. Holders should consult their own tax advisors as to the foreign tax credit implications of a disposition of the notes.

     A Non-U.S. Holder generally will not be subject to U.S. federal income or withholding tax on gain realized on the sale or other taxable disposition of notes unless (i) such gain is effectively connected with the conduct by the Non-U.S. Holder of a trade or business in the United States or (ii) in the case of gain realized by an individual, such Non-U.S. Holder is present in the United States for 183 days or more in the taxable year of the disposition and certain other conditions are met. Non-U.S. Holders should consult their own tax advisors in the event either of the foregoing conditions apply.

     Backup Withholding and Information Reporting

     Payments in respect of the notes that are paid within the United States or through certain U.S.-related financial intermediaries are subject to information reporting, and may be subject to backup withholding, unless the U.S. Holder (i) is a corporation or other exempt recipient, and demonstrates this fact when so required, or (ii) provides a correct taxpayer identification number, certifies that it is not subject to backup withholding and otherwise complies with applicable requirements of the backup withholding rules. The amount of any backup withholding collected from a payment to a U.S. Holder will be allowed as a credit against the U.S. Holder’s U.S. federal income tax liability, and may entitle the U.S. Holder to a refund, provided that certain required information is timely furnished to the Internal Revenue Service.

     Although Non-U.S. Holders generally are exempt from backup withholding, a Non-U.S. Holder may, in certain circumstances, be required to comply with certification procedures to prove entitlement to this exemption.

Brazilian Tax Considerations

     The following discussion is a summary of the Brazilian tax considerations relating to an investment in the notes by a non-resident of Brazil. The discussion is based on the tax laws of Brazil as in effect on the date of this prospectus supplement and is subject to any change in Brazilian law that may come into effect after such date. The

information set forth below is intended to be a general discussion only and does not address all possible tax consequences relating to an investment in the notes.

     PROSPECTIVE INVESTORS SHOULD CONSULT THEIR OWN TAX ADVISERS AS TO THE CONSEQUENCES OF PURCHASING THE SECURITIES, INCLUDING, WITHOUT LIMITATION, THE CONSEQUENCES OF THE RECEIPT OF INTEREST AND THE SALE, REDEMPTION OR REPAYMENT OF THE NOTES OR COUPONS.

     Generally, an individual, entity, trust or organization domiciled for tax purposes outside Brazil, or a “Non-resident,” is taxed in Brazil only when income is derived from Brazilian sources or when the transaction giving rise to such earnings involves assets in Brazil. Therefore, any gains or interest (including original issue discount), fees, commissions, expenses and any other income paid by PifCo in respect of the notes issued by it in favor of Non-resident holders are not subject to Brazilian taxes.

     Interest, fees, commissions, expenses and any other income payable by a an issuer or guarantor resident in Brazil to a Non-resident are generally subject to income tax withheld at source. The rate of withholding tax in respect of interest payments is generally 15%, unless (i) the noteholder is resident or domiciled in a “tax haven” jurisdiction (that is deemed to be a jurisdiction which does not impose any tax on income or which imposes such tax at a maximum effective rate lower than 20%), in which case the applicable rate is 25% (the withholding rate remains 15% in the case of interest income payable by a Brazilian obligor to an individual, company, trust or organization domiciled outside Brazil in respect of debt obligations resulting from the issuance by a Brazilian issuer of international debt securities previously registered with the Central Bank, including commercial papers, as provided for in Section 10 of Normative Instruction no. 252, dated December 3, 2002 issued by the Brazilian Revenue Service); or (ii) such other lower rate as provided for in an applicable tax treaty between Brazil and another country where the beneficiary is domiciled.

     If the payments with respect to the notes are made by Petrobras, as provided for in the guaranty, the holders will be indemnified so that, after payment of all applicable Brazilian taxes collectable by withholding, deduction or otherwise, with respect to principal, interest and additional amounts payable with respect to the notes (plus any interest and penalties thereon), a holder will retain an amount equal to the amounts that such holder would have retained had no such Brazilian taxes (plus interest and penalties thereon) been payable. The Brazilian obligor will, subject to certain exceptions, pay additional amounts in respect of such withholding or deduction so that the holder receives the net amount due.

     Gains on the sale or other disposition of the notes made outside Brazil by a Non-resident, other than a branch or a subsidiary of Brazilian resident, to another Non-resident are not subject to Brazilian taxes. Gains made by a Brazilian Non-resident from the sale or other disposition of these notes to a Brazilian resident, subject to certain assumptions and conditions, are not subject to Brazilian taxes.

     In addition, payments made from Brazil are subject to the tax on foreign exchange transactions (IOF/Câmbio), which is levied on the conversion of Brazilian currency into foreign currency at a current rate of 0.38%.

     Generally, there are no inheritance, gift, succession, stamp, or other similar taxes in Brazil with respect to the ownership, transfer, assignment or any other disposition of the notes by a Non-resident, except for gift and inheritance taxes imposed by some Brazilian states on gifts or bequests by individuals or entities not domiciled or residing in Brazil to individuals or entities domiciled or residing within such states.

Cayman Islands Tax Considerations

     The Cayman Islands currently have no exchange control restrictions and no income, corporate or capital gains tax, estate duty, inheritance tax, gift tax or withholding tax applicable to PifCo or any holder of notes issued by PifCo. Accordingly, payment of principal of (including any premium) and interest on, and any transfer of, the notes will not be subject to taxation in the Cayman Islands; no Cayman Islands withholding tax will be required on such payments to any holder of a note; and gains derived from the sale of notes will not be subject to Cayman Islands capital gains tax. The Cayman Islands are not party to any double taxation treaties.

     No stamp duties or similar taxes or charges are payable under the laws of the Cayman Islands in respect of the execution and issue of notes by PifCo unless they are executed in or brought within (for example, for the purposes of enforcement) the jurisdiction of the Cayman Islands, in which case stamp duty of 0.25% of the face amount of the notes may be payable on each note (up to a maximum of 250 Cayman Islands Dollars (“CI$”) (U.S.$312.50)) unless stamp duty of CI$500 (U.S.$625.00) has been paid in respect of the entire issue of notes.

     The foregoing conversions of Cayman Island Dollars to U.S. Dollars have been made on the currently applicable basis of U.S.$1.25 = CI$1.00.

European Union Savings Directive

     Under European Council Directive 2003/48/EC (the “Directive”) on the taxation of savings income, each Member State of the European Union is required to provide to the tax or other relevant authorities of another Member State details of payments of interest or other similar income paid by a person within its jurisdiction to an individual beneficial owner who is resident in that other Member State. However, for a transitional period, Austria, Belgium and Luxembourg will (unless during such period they elect otherwise) instead apply a withholding system in relation to such payments, withholding tax at rates rising over time to 35 percent unless the recipient of the interest payment elects instead for an exchange of information procedure. Any withholding tax levied pursuant to the Directive may be in addition to any domestic withholding tax levied by Member States.

     The transitional period is to terminate at the end of the first full fiscal year following agreement by certain non European Union countries to similar exchange of information procedures relating to interest and other similar payments.

     A number of non-European Union countries and certain dependent or associated territories of certain Member States have agreed to adopt similar measures (either provision of information or transitional withholding) in relation to payments made by a person within their respective jurisdictions to an individual beneficial owner who is resident in a Member State. In addition, the Member States have entered into reciprocal provision of information or transitional withholding arrangements with certain of those dependent or associated territories in relation to payments made by a person in a Member State to an individual beneficial owner who is resident in one of those territories.

LEGAL MATTERS

     Walkers, special Cayman Islands counsel for PifCo, will pass upon the validity of the notes and the indenture for PifCo as to certain matters of Cayman Islands law. Mr. Nilton Antonio de Almeida Maia, Petrobras’ general counsel, will pass upon, for PifCo and Petrobras, certain matters of Brazilian law relating to the notes, the indenture and the guaranty. The validity of the notes, the indenture and the guaranty will be passed upon for PifCo and Petrobras by Cleary Gottlieb Steen & Hamilton LLP as to certain matters of New York law.

     Souza, Cescon Avedissian, Barrieu e Flesch Advogados will pass upon the validity of the indenture and the guaranty for the underwriters as to certain matters of Brazilian law. Shearman & Sterling LLP will pass upon the validity of the notes, the indenture and the guaranty for the underwriters as to certain matters of New York law.

EXPERTS

     The consolidated financial statements of Petrobras (and its subsidiaries) and of PifCo (and its subsidiaries) as of and for the years ended December 31, 2007, and 2006, and management’s assessments of the effectiveness of internal control over financial reporting as of December 31, 2007, have been incorporated by reference herein in reliance upon the report of KPMG Auditores Independentes, an independent registered public accounting firm, which is incorporated by reference herein, and upon the authority of KPMG Auditores Independentes as experts in accounting and auditing. The report covering the December 31, 2007 financial statements of Petrobras (and its subsidiaries) refers to the adoption of the recognition and disclosure provisions of Financial Accounting Standards Board (“FASB”) Interpretation No. 48, Accounting for Uncertainty in Income Taxes—an interpretation of FASB Statement No. 109 (FIN 48).

     The consolidated financial statements of Petrobras (and its subsidiaries) and of PifCo (and its subsidiaries) for the year ended December 31, 2005, have been incorporated by reference herein in reliance upon the report of Ernst & Young Auditores Independentes S/S, independent registered public accounting firm, which is incorporated by reference herein, and upon the authority of Ernst & Young Auditores Independentes S/S as experts in accounting and auditing.

     With respect to the unaudited interim financial information of Petrobras and PifCo for the periods ended September 30, 2008 and 2007, which is incorporated by reference herein, KPMG Auditores Independentes has reported that it applied limited procedures in accordance with professional standards for a review of such information. However, its reports included in the Petrobras Form 6-K furnished to the SEC on November 28, 2008, and PifCo Form 6-K furnished to the SEC on November 28, 2008, and incorporated by reference herein, state that it did not audit and it does not express an opinion on that interim financial information. Accordingly, the degree of reliance on its reports on such information should be restricted in light of the limited nature of the review procedures applied. KPMG Auditores Independentes is not subject to the liability provisions of Section 11 of the Securities Act for its reports on the unaudited interim financial information because those reports are not “reports” or a “part” of the registration statement prepared or certified by the accountants within the meaning of Sections 7 and 11 of the Securities Act.

This prospectus only provides a general description of the securities that we may offer. Each time we offer securities, we will prepare a prospectus supplement containing specific information about the particular offering and the terms of those securities. We may also add, update or change other information contained in this prospectus by means of a prospectus supplement or by incorporating by reference information we file with the SEC. The registration statement that we filed with the SEC includes exhibits that provide more detail on the matters discussed in this prospectus. Before you invest in any securities offered by this prospectus, you should read this prospectus, any related prospectus supplement and the related exhibits filed with the SEC, together with the additional information described under the headings “Where You Can Find More Information” and “Incorporation of Certain Documents by Reference.”

 

FORWARD-LOOKING STATEMENTS

 

Many statements made or incorporated by reference in this prospectus supplement are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”) and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), that are not based on historical facts and are not assurances of future results.

Petrobras is controlled by the Brazilian federal government, but its common and preferred shares are publicly traded.

 

Petrobras is one of the world’s largest integrated oil and gas companies, engaging in a broad range of oil and gas activities.

 

Petrobras engages in a broad range of activities, which cover the following segments of its operations:

LEGAL OWNERSHIP

 

In this prospectus and in any attached prospectus supplement, when we refer to the “holders” of securities as being entitled to specified rights or payments, we mean only the actual legal holders of the securities. While you will be the holder if you hold a security registered in your name, more often than not the registered holder will actually be either a broker, bank, other financial institution or, in the case of a global security, a depositary. Our obligations, as well as the obligations of the trustee, any warrant agent, any transfer agent, any registrar, any depositary and any third parties employed by us or the other entities listed above, run only to persons who are registered as holders of our securities, except as may be specifically provided for in a warrant agreement, warrant certificate, deposit agreement or other contract governing the securities. For example, once we make payment to the registered holder, we have no further responsibility for the payment even if that registered holder is legally required to pass the payment along to you as a street name customer but does not do so.

 

If we choose to issue preferred shares or common shares, they may be evidenced by ADRs and you will hold them indirectly through ADSs. The underlying preferred shares or common shares will be directly held by a depositary. Your rights and obligations will be determined by reference to the terms of the relevant deposit agreement. A copy of the deposit agreements, as amended from time to time, with respect to our preferred shares and common shares is on file with the SEC and incorporated by reference in this prospectus. You may obtain copies of the deposit agreements from the SEC’s Public Reference Room. See “Where You Can Find More Information.”

 

Street Name and Other Indirect Holders

 

Holding securities in accounts at banks or brokers is called holding in “street name.” If you hold our securities in street name, we will recognize only the bank or broker, or the financial institution that the bank or broker uses to hold the securities, as a holder. These intermediary banks, brokers, other financial institutions and depositaries pass along principal, interest, dividends and other payments, if any, on the securities, either because they agree to do so in their customer agreements or because they are legally required to do so. This means that if you are an indirect

holder, you will need to coordinate with the institution through which you hold your interest in a security in order to determine how the provisions involving holders described in this prospectus and any prospectus supplement will actually apply to you. For example, if the debt security in which you hold a beneficial interest in street name can be repaid at the option of the holder, you cannot redeem it yourself by following the procedures described in the prospectus supplement relating to that security. Instead, you would need to cause the institution through which you hold your interest to take those actions on your behalf. Your institution may have procedures and deadlines different from or additional to those described in the applicable prospectus supplement.

 

If you hold our securities in street name or through other indirect means, you should check with the institution through which you hold your interest in a security to find out:

 

 

Global Securities

 

A global security is a special type of indirectly held security. If we choose to issue our securities, in whole or in part, in the form of global securities, the ultimate beneficial owners can only be indirect holders. We do this by requiring that the global security be registered in the name of a financial institution we select and by requiring that the securities included in the global security not be transferred to the name of any other direct holder unless the special circumstances described below occur. The financial institution that acts as the sole direct holder of the global security is called the “depositary.” Any person wishing to own a security issued in global form must do so indirectly through an account with a broker, bank or other financial institution that in turn has an account with the depositary. The prospectus supplement indicates whether the securities will be issued only as global securities.

 

As an indirect holder, your rights relating to a global security will be governed by the account rules of your financial institution and of the depositary, as well as general laws relating to securities transfers. We will not recognize you as a holder of the securities and instead deal only with the depositary that holds the global security.

 

You should be aware that if our securities are issued only in the form of global securities:

 

 

In a few special situations described below, a global security representing our securities will terminate and interests in it will be exchanged for physical certificates representing the securities. After that exchange, the choice of whether to hold securities directly or in street name will be up to you. You must consult your bank or broker to find out how to have your interests in the securities transferred to your name, so that you will be a direct holder.

 

Unless we specify otherwise in the prospectus supplement, the special situations for termination of a global security representing our securities are:

 

 

The prospectus supplement may also list additional situations for terminating a global security that would apply to the particular series of securities covered by the prospectus supplement. When a global security terminates, the depositary (and not us, the trustee, any warrant agent, any transfer agent or any registrar) is responsible for deciding the names of the institutions that will be the initial direct holders.

 

 

 

 

 

DESCRIPTION OF DEBT SECURITIES

 

The following briefly summarizes the material provisions of the debt securities and the Petrobras or PIFCo indenture that will govern the debt securities, other than pricing and related terms disclosed in the accompanying prospectus supplement. You should read the more detailed provisions of the applicable indenture, including the defined terms, for provisions that may be important to you. You should also read the particular terms of a series of debt securities, which will be described in more detail in the applicable prospectus supplement. This summary is subject to, and qualified in its entirety by reference to, the provisions of such indenture, the debt securities and the prospectus supplement relating to each series of debt securities.

 

Indenture

 

Any debt securities that we issue will be governed by a document called an indenture. The indenture is a contract entered into between any one of us and a trustee, currently The Bank of New York. The trustee has two main roles:

 

 

Each of the Petrobras and PIFCo indentures and their associated documents contain the full legal text of the matters described in this section. We have agreed that New York law governs the indenture and the debt securities. We have filed a copy of the Petrobras indenture and PIFCo indenture with the SEC as exhibits to our registration statement. We have consented to the non-exclusive jurisdiction of any U.S. federal court sitting in the borough of Manhattan in the City of New York, New York, United States and any appellate court from any thereof.

 

Types of Debt Securities

 

Together or separately, we may issue as many distinct series of debt securities under our indentures as are authorized by the corporate bodies that are required under applicable law and our corporate organizational documents to authorize the issuance of debt securities. Specific issuances of debt securities will also be governed by a supplemental indenture, an officer’s certificate or a document evidencing the authorization of any such corporate body. This section summarizes material terms of the debt securities that are common to all series and to each of the Petrobras and PIFCo indentures, unless otherwise indicated in this section and in the prospectus supplement relating to a particular series.

 

Because this section is a summary, it does not describe every aspect of the debt securities. This summary is subject to and qualified in its entirety by reference to all the provisions of the indenture, including the definition of various terms used in the indenture. For example, we describe the meanings for only the more important terms that have been given special meanings in the indenture. We also include references in parentheses to some sections of the indenture. Whenever we refer to particular sections or defined terms of our indentures in this prospectus or in any prospectus supplement, those sections or defined terms are incorporated by reference herein or in such prospectus supplement.

 

We may issue the debt securities at par, at a premium or as original issue discount securities, which are debt securities that are offered and sold at a substantial discount to their stated principal amount. We may also issue the debt securities as indexed securities or securities denominated in currencies other than the U.S. dollar, currency units or composite currencies, as described in more detail in the prospectus supplement relating to any such debt securities. We will describe the U.S. federal income tax consequences and any other special considerations applicable to original issue discount, indexed or foreign currency debt securities in the applicable prospectus supplement(s).

 

In addition, the material financial, legal and other terms particular to a series of debt securities will be described in the prospectus supplement(s) relating to that series. Those terms may vary from the terms described

here. Accordingly, this summary also is subject to and qualified by reference to the description of the terms of the series described in the applicable prospectus supplement(s).

 

The prospectus supplement relating to a series of debt securities will describe the following terms of the series:

 

 

 

In addition, the prospectus supplement will state whether we will list the debt securities of the series on any stock exchange(s) and, if so, which one(s).

 

Additional Mechanics

 

Form, exchange and transfer

 

The debt securities will be issued, unless otherwise indicated in the applicable prospectus supplement, in denominations that are even multiples of $1,000 and in global registered form. (Petrobras Section 3.02; PIFCo Section 3.02)

 

You may have your debt securities broken into more debt securities of smaller denominations or combined into fewer debt securities of larger denominations, as long as the total principal amount is not changed. This is called an exchange. (Petrobras Section 3.05; PIFCo Section 3.05)

 

You may exchange or transfer your registered debt securities at the office of the trustee. The trustee will maintain an office in New York, New York. The trustee acts as our agent for registering debt securities in the names of holders and transferring registered debt securities. We may change this appointment to another entity or perform the service ourselves. The entity performing the role of maintaining the list of registered holders is called the “security registrar.” It will also register transfers of the registered debt securities. (Petrobras Section 3.05; PIFCo Section 3.05)

 

You will not be required to pay a service charge to transfer or exchange debt securities, but you may be required to pay any tax or other governmental charge associated with the exchange or transfer. The transfer or exchange of a registered debt security will only be made if the security registrar is satisfied with your proof of ownership.

 

If we designate additional transfer agents, they will be named in the prospectus supplement. We may cancel the designation of any particular transfer agent. Petrobras may also approve a change in the office through which any transfer agent acts. (Petrobras Section 10.02; PIFCo Section 10.03)

 

If the debt securities are redeemable and we redeem less than all of the debt securities of a particular series, we may block the transfer or exchange of debt securities in order to freeze the list of holders to prepare the mailing during the period beginning 15 days before the day we mail the notice of redemption and ending on the day of that mailing. We may also refuse to register transfers or exchanges of debt securities selected for redemption. However, we will continue to permit transfers and exchanges of the unredeemed portion of any debt security being partially redeemed. (Petrobras Section 3.05; PIFCo Section 3.05)

 

Payment and paying agents

 

If your debt securities are in registered form, we will pay interest to you if you are a direct holder listed in the trustee’s records at the close of business on a particular day in advance of each due date for interest, even if you no longer own the security on the interest due date. That particular day, usually about two weeks in advance of the interest due date, is called the “regular record date” and will be stated in the prospectus supplement. (Petrobras Section 3.07; PIFCo Section 3.07)

 

We will pay interest, principal, additional amounts and any other money due on the registered debt securities at the corporate trust office of the trustee in New York City (which is currently located at 101 Barclay Street, 4E, New York, New York 10286, Attention: Global Trust Services — Americas) or at the office of JPMorgan Trust Bank

Limited, a bank established under the laws of Japan (which is currently located at Tokyo Building, 7-3, Marunouchi 2-chome, Chiyoda-ku, Tokyo 100-6432, Japan). You must make arrangements to have your payments picked up at or wired from that office. We may also choose to pay interest by mailing checks. Interest on global securities will be paid to the holder thereof by wire transfer of same-day funds.

 

Holders buying and selling debt securities must work out between themselves how to compensate for the fact that we will pay all the interest for an interest period to, in the case of registered debt securities, the one who is the registered holder on the regular record date. The most common manner is to adjust the sales price of the debt securities to pro-rate interest fairly between the buyer and seller. This pro-rated interest amount is called “accrued interest.”

 

 

 

 

We may also arrange for additional payment offices, and may cancel or change these offices, including our use of the trustee’s corporate trust office. These offices are called “paying agents.” We may also choose to act as our own paying agent. We must notify you of changes in the paying agents for the debt securities of any series that you hold. (Petrobras Section 10.02; PIFCo Section 10.03)

 

Notices

 

We and the trustee will send notices only to direct holders, using their addresses as listed in the trustee’s records. (Petrobras Section 1.06; PIFCo Section 1.06)

 

Regardless of who acts as paying agent, all money that Petrobras pays to a paying agent that remains unclaimed at the end of two years after the amount is due to direct holders will be repaid to Petrobras. After that two-year period, direct holders may look only to Petrobras for payment and not to the trustee, any other paying agent or anyone else. (Petrobras Section 10.03)

 

Special Situations

 

Mergers and similar events

 

Under the indenture, except as described below, we are generally permitted to consolidate or merge with another entity. We are also permitted to sell or lease substantially all of our assets to another entity or to buy or lease substantially all of the assets of another entity. No vote by holders of debt securities approving any of these actions is required, unless as part of the transaction we make changes to the indenture requiring your approval, as described later under “— Modification and Waiver.” We may take these actions as part of a transaction involving outside third parties or as part of an internal corporate reorganization. We may take these actions even if they result in:

 

 

We have no obligation under the indenture to seek to avoid these results, or any other legal or financial effects that are disadvantageous to you, in connection with a merger, consolidation or sale or lease of assets that is permitted under the indenture.

 

Petrobras

 

Petrobras may merge into or consolidate with or convey, transfer or lease its property to another entity, provided that it may not take any of these actions unless all the following conditions are met:

 

 

 

PIFCo

 

PIFCo will not, in one or a series of transactions, consolidate or 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 (other than a direct or indirect subsidiary of Petrobras) or permit any person (other than a direct or indirect subsidiary of PIFCo) to merge with or into it unless:

 

 

Notwithstanding anything to the contrary in the foregoing, so long as no default or event of default under the indenture or the notes will have occurred and be continuing at the time of the proposed transaction or would result from the transaction:

 

 

It is possible that the U.S. Internal Revenue Service may deem a merger or other similar transaction to cause for U.S. federal income tax purposes an exchange of debt securities for new securities by the holders of the debt securities. This could result in the recognition of taxable gain or loss for U.S. federal income tax purposes and possible other adverse tax consequences.

 

Modification and waiver

 

There are three types of changes we can make to the indenture and the debt securities.

 

Changes Requiring Your Approval.  First, there are changes that cannot be made to your debt securities without your specific approval. These are the following types of changes:

 

 

Changes Requiring a Majority Vote.  The second type of change to the indenture and the debt securities is the kind that requires a vote of approval by the holders of debt securities that together represent a majority of the

outstanding principal amount of the particular series affected. Most changes fall into this category, except for clarifying changes, amendments, supplements and other changes that would not adversely affect holders of the debt securities in any material respect. For example, this vote would be required for us to obtain a waiver of all or part of any covenants described in an applicable prospectus supplement or a waiver of a past default. However, we cannot obtain a waiver of a payment default or any other aspect of the indenture or the debt securities listed in the first category described previously beginning above under “Changes Requiring Your Approval” unless we obtain your individual consent to the waiver. (Petrobras Sections 5.13 and 9.02; PIFCo Sections 5.13 and 9.02)

 

Changes Not Requiring Approval.  The third type of change does not require any vote by holders of debt securities. This type is limited to clarifications of ambiguities, omissions, defects and inconsistencies, amendments, supplements and other changes that would not adversely affect holders of the debt securities in any material respect, such as adding covenants, additional events of default or successor trustees. (Petrobras Section 9.01; PIFCo Section 9.01)

 

Further Details Concerning Voting.  When taking a vote, we will use the following rules to decide how much principal amount to attribute to a security:

 

 

Debt securities will not be considered outstanding, and therefore will not be eligible to vote, if we have deposited or set aside in trust for you money for their payment or redemption. Debt securities will also not be eligible to vote if they have been fully defeased as described under “Defeasance and Discharge.” (Petrobras Section 14.02; PIFCo Section 14.02)

 

We will generally be entitled to set any day as a record date for the purpose of determining the holders of outstanding debt securities that are entitled to vote or take other action under the indenture. In limited circumstances, the trustee will be entitled to set a record date for action by holders. If we or the trustee set a record date for a vote or other action to be taken by holders of a particular series, that vote or action may be taken only by persons who are holders of outstanding debt securities of that series on the record date and must be taken within 180 days following the record date or another period that we or, if it sets the record date, the trustee may specify. We may shorten or lengthen (but not beyond 180 days) this period from time to time. (Petrobras Section 1.04; PIFCo Section 1.04)

 

 

 

 

Redemption and repayment

 

Unless otherwise indicated in the applicable prospectus supplement, your debt security will not be entitled to the benefit of any sinking fund; that is, we will not deposit money on a regular basis into any separate custodial account to repay your debt securities. In addition, other than as set forth in “Optional Tax Redemption” below, we will not be entitled to redeem your debt security before its stated maturity unless the applicable prospectus supplement specifies a redemption commencement date. You will not be entitled to require us to buy your debt security from you, before its stated maturity, unless the applicable prospectus supplement specifies one or more repayment dates.

If the applicable prospectus supplement specifies a redemption commencement date or a repayment date, it will also specify one or more redemption prices or repayment prices, which may be expressed as a percentage of the principal amount of your debt security or by reference to one or more formulae used to determine the redemption price(s). It may also specify one or more redemption periods during which the redemption prices relating to a redemption of debt securities during those periods will apply.

 

If the applicable prospectus supplement specifies a redemption commencement date, we may redeem your debt security at our option at any time on or after that date. If we redeem your debt security, we will do so at the specified redemption price, together with interest accrued to the redemption date. If different prices are specified for different redemption periods, the price we pay will be the price that applies to the redemption period during which your debt security is redeemed. If less than all of the debt securities are redeemed, the trustee will choose the debt securities to be redeemed by lot, or in the trustee’s discretion, pro rata. (Petrobras Section 11.03; PIFCo Section 11.03)

 

If the applicable prospectus supplement specifies a repayment date, your debt security will be repayable by us at your option on the specified repayment date(s) at the specified repayment price(s), together with interest accrued and any additional amounts to the repayment date. (Petrobras Section 11.04; PIFCo Section 11.04)

 

In the event that we exercise an option to redeem any debt security, we will give to the trustee and the holder written notice of the principal amount of the debt security to be redeemed, not less than 30 days nor more than 60 days before the applicable redemption date. We will give the notice in the manner described above under “Additional Mechanics — Notices.”

 

If a debt security represented by a global security is subject to repayment at the holder’s option, the depositary or its nominee, as the holder, will be the only person that can exercise the right to repayment. Any indirect holders who own beneficial interests in the global security and wish to exercise a repayment right must give proper and timely instructions to their banks or brokers through which they hold their interests, requesting that they notify the depositary to exercise the repayment right on their behalf. Different firms have different deadlines for accepting instructions from their customers, and you should take care to act promptly enough to ensure that your request is given effect by the depositary before the applicable deadline for exercise.

 

 

 

 

In the event that the option of the holder to elect repayment as described above is deemed to be a “tender offer” within the meaning of Rule 14e-1 under the Securities Exchange Act of 1934, we will comply with Rule 14e-1 as then in effect to the extent it is applicable to us and the transaction.

 

Subject to any restrictions that will be described in the prospectus supplement, we or our affiliates may purchase debt securities from investors who are willing to sell from time to time, either in the open market at prevailing prices or in private transactions at negotiated prices. Debt securities that we or they purchase may, in our discretion, be held, resold or canceled.

 

Optional tax redemption

 

Unless otherwise indicated in a prospectus supplement, we may have the option to redeem, in whole but not in part, the debt securities where, as a result of a change in, execution of or amendment to any laws or treaties or the official application or interpretation of any laws or treaties, we would be required to pay additional amounts as described later under “Payment of Additional Amounts.” This applies only in the case of changes, executions or amendments that occur on or after the date specified in the prospectus supplement for the applicable series of debt securities and in the jurisdiction where we are incorporated. If succeeded by another entity, the applicable jurisdiction will be the jurisdiction in which such successor entity is organized, and the applicable date will be the date the entity became a successor. (Petrobras Section 11.08; PIFCo Section 11.08)

If the debt securities are redeemed, the redemption price for debt securities (other than original issue discount debt securities) will be equal to the principal amount of the debt securities being redeemed plus accrued interest and any additional amounts due on the date fixed for redemption. The redemption price for original issue discount debt securities will be specified in the prospectus supplement for such securities. Furthermore, we must give you between 30 and 60 days’ notice before redeeming the debt securities.

 

Conversion

 

Your debt securities may be convertible into or exchangeable for shares of our capital stock at your option or at our option, which may be represented by ADSs, or other securities if your prospectus supplement so provides. If your debt securities are convertible or exchangeable, your prospectus supplement will include provisions as to whether conversion or exchange is at your option or at our option. Your prospectus supplement would also include provisions regarding the adjustment of the number of securities to be received by you upon conversion or exchange.

 

Payment of Additional Amounts

 

Petrobras

 

Brazil (including any authority therein or thereof having the power to tax) may require Petrobras to withhold amounts from payments on the principal or any premium or interest on a debt security for taxes or any other governmental charges. If Brazil requires a withholding of this type, Petrobras is required, subject to the exceptions listed below, to pay you an additional amount so that the net amount you receive will be the amount specified in the debt security to which you are entitled. However, in order for you to be entitled to receive the additional amount, you must not be a resident of Brazil.

 

Petrobras will not have to pay additional amounts under any of the following circumstances:

 

 

 

 

The prospectus supplement relating to the debt securities may describe additional circumstances in which Petrobras would not be required to pay additional amounts. (Petrobras Section 10.04)

 

PIFCo

 

Except as provided below, PIFCo will make all payments of amounts due under the notes and the indenture and each other document entered into in connection with the notes and the indenture without withholding or deducting any present or future taxes, levies, deductions or other governmental charges of any nature imposed by Brazil, the jurisdiction of PIFCo’s incorporation or any jurisdiction in which PIFCo appoints a paying agent under the indenture, or any political subdivision of such jurisdictions (the “taxing jurisdictions”). If PIFCo is required by law to withhold or deduct any taxes, levies, deductions or other governmental charges, PIFCo will make such deduction or withholding, make payment of the amount so withheld to the appropriate governmental authority and pay the noteholders any additional amounts necessary to ensure that they receive the same amount as they would have received without such withholding or deduction.

 

PIFCo will not, however, pay any additional amounts in connection with any tax, levy, deduction or other governmental charge that is imposed due to any of the following (“excluded additional amounts”):

 

 

PIFCo undertakes that, if European Council Directive 2003/48/EC or any other Directive implementing the conclusions of ECOFIN council meeting of November 26-27, 2000 is brought into effect, PIFCo will ensure that it maintains a paying agent in a member state of the European Union that will not be obliged to withhold or deduct tax pursuant to the Directive.

 

PIFCo will pay any stamp, administrative, excise or property taxes arising in a taxing jurisdiction in connection with the execution, delivery, enforcement or registration of the notes and will indemnify the noteholders for any such stamp, administrative, excise or property taxes paid by noteholders. (PIFCo Section 10.10)

 

Restrictive Covenants

 

Petrobras

 

The Petrobras indenture does not contain any covenants restricting the ability of Petrobras to make payments, incur indebtedness, dispose of assets, enter into sale and leaseback transactions, issue and sell capital stock, enter into transactions with affiliates, create or incur liens on Petrobras’ property or engage in business other than its present business. Restrictive covenants, if any, with respect to any securities of Petrobras will be contained in the applicable supplemental indenture and described in the applicable prospectus supplement with respect to those securities. (Petrobras Section 10)

 

PIFCo

 

PIFCo will be subject to the following covenants with respect to the notes:

 

Ranking

 

PIFCo will ensure that the notes will at all times constitute its general senior, unsecured and unsubordinated obligations and will rank pari passu, without any preferences among themselves, with all of its other present and future unsecured and unsubordinated obligations (other than obligations preferred by statute or by operation of law). (PIFCo Section 10.04)

 

Statement by officers as to default and notices of events of default

 

PIFCo (and each other obligor on the notes) will deliver to the trustee, within 90 calendar days after the end of its fiscal year, an officer’s certificate, stating whether or not to the best knowledge of its signers PIFCo is in default on any of the terms, provisions and conditions of the indenture or the notes (without regard to any period of grace or requirement of notice provided under the indenture) and, if PIFCo (or any obligor) are in default, specifying all the defaults and their nature and status of which the signers may have knowledge. Within 10 calendar days (or promptly with respect to certain events of default relating to PIFCo’s insolvency and in any event no later than 10 calendar days) after PIFCo becomes aware or should reasonably become aware of the occurrence of any default or event of default under the indenture or the notes, it will notify the trustee of the occurrence of such default or event of default. (PIFCo Section 10.05)

 

Provision of financial statements and reports

 

In the event that PIFCo files any financial statements or reports with the SEC or publishes or otherwise makes such statements or reports publicly available in Brazil, the United States or elsewhere, PIFCo will furnish a copy of the statements or reports to the trustee within 15 calendar days of the date of filing or the date the information is published or otherwise made publicly available.

 

PIFCo will provide, together with each of the financial statements delivered as described in the preceding paragraph, an officer’s certificate stating (i) that a review of PIFCo’s activities has been made during the period covered by such financial statements with a view to determining whether PIFCo has kept, observed, performed and fulfilled its covenants and agreements under this indenture; and (ii) that no event of default, or event which with the giving of notice or passage of time or both would become an event of default, has occurred during that period or, if one or more have actually occurred, specifying all those events and what actions have been taken and will be taken with respect to that event of default or other event.

Delivery of these reports, information and documents to the trustee is for informational purposes only and the trustee’s receipt of any of those will not constitute constructive notice of any information contained in them or determinable from information contained in them, including PIFCo’s compliance with any of its covenants under the indenture (as to which the trustee is entitled to rely exclusively on officer’s certificates). (PIFCo Section 10.06)

 

Additional restrictive covenants with respect to securities of PIFCo may be contained in the applicable supplemental indenture and described in the applicable prospectus supplement with respect to those securities.

 

Defeasance and Discharge

 

The following discussion of full defeasance and discharge and covenant defeasance and discharge will only be applicable to your series of debt securities if we choose to apply them to that series, in which case we will state that in the prospectus supplement. (Petrobras Section 14.01; PIFCo Section 14.01)

 

Full defeasance

 

We can legally release ourselves from any payment or other obligations on the debt securities, except for various obligations described below (called “full defeasance”), if we, in addition to other actions, put in place the following arrangements for you to be repaid:

 

 

If we ever did accomplish full defeasance as described above, you would have to rely solely on the trust deposit for repayment on the debt securities. You could not look to us for repayment in the unlikely event of any shortfall. Conversely, the trust deposit would most likely be protected from claims of our lenders and other creditors if we ever become bankrupt or insolvent. However, even if we take these actions, a number of our obligations relating to the debt securities will remain. These include the following obligations:

 

 

Covenant defeasance

 

We can make the same type of deposit described above and be released from all or some of the restrictive covenants (if any) that apply to the debt securities of any particular series. This is called “covenant defeasance.” In that event, you would lose the protection of those restrictive covenants but would gain the protection of having

money and securities set aside in trust to repay the debt securities. In order to achieve covenant defeasance, we must do the following:

 

 

If we accomplish covenant defeasance, the following provisions of the indenture and/or the debt securities would no longer apply:

 

 

If we accomplish covenant defeasance, you can still look to us for repayment of the debt securities if there were a shortfall in the trust deposit. In fact, if any event of default occurred (such as our bankruptcy) and the debt securities become immediately due and payable, there may be such a shortfall. Depending on the event causing the default, you may not be able to obtain payment of the shortfall. (Petrobras Sections 14.03 and 14.04; PIFCo Sections 14.03 and 14.04)

 

Default and Related Matters

 

Ranking

 

The applicable prospectus supplement will indicate whether the debt securities are subordinated to any of our other debt obligations and whether they will be secured by any of our assets. If they are not subordinated, they will rank equally with all our other unsecured and unsubordinated indebtedness. If they are not secured, the securities will effectively be subordinate to our secured indebtedness and to the indebtedness of our subsidiaries.

 

Events of default

 

You will have special rights if an event of default occurs and is not cured, as described later in this subsection.

 

What Is an Event of Default? The term event of default means any of the following:

 

 

 

For these purposes, “indebtedness” means any obligation (whether present or future, actual or contingent and including any guarantee) for the payment or repayment of money which has been borrowed or raised (including money raised by acceptances and all leases which, under generally accepted accounting principles in the United States, would be a capital lease obligation).

An event of default for a particular series of debt securities does not necessarily constitute an event of default for any other series of debt securities issued under the indenture, although the default and acceleration of one series of debt securities may trigger a default and acceleration of another series of debt securities.

 

Remedies if an Event of Default Occurs.  If an event of default has occurred and has not been cured, the trustee or the holders of 25% in principal amount of the debt securities of the affected series may declare the entire principal amount of all the debt securities of that series to be due and immediately payable. This is called a declaration of acceleration of maturity. If an event of default occurs because of certain events in bankruptcy, insolvency or reorganization, or an equivalent proceeding under Brazilian law, the principal amount of all the debt securities of that series will be automatically accelerated without any action by the trustee, any holder or any other person. A declaration of acceleration of maturity may be canceled by the holders of at least a majority in principal amount of the debt securities of the affected series. (Petrobras Section 5.02; PIFCo Section 5.02)

 

Except in cases of default, where the trustee has some special duties, the trustee is not required to take any action under the indenture at the request of any holders unless the holders offer the trustee reasonably satisfactory protection from expenses and liability. This protection is called an “indemnity.” (Petrobras Section 6.03; Section 6.03) If reasonable indemnity is provided, the holders of a majority in principal amount of the outstanding debt securities of the relevant series may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the trustee. These same holders may also direct the trustee in performing any other action under the indenture. (Petrobras Section 5.12; PIFCo Section 5.12) Before you bypass the trustee and bring your own lawsuit or other formal legal action or take other steps to enforce your rights or protect your interests relating to the debt securities, the following must occur:

 

 

However, you are entitled at any time to bring a lawsuit for the payment of money due on your debt security on or after its due date and if your debt security is convertible or exchangeable into another security to bring a lawsuit for the enforcement of your right to convert or exchange your debt security or to receive securities upon conversion or exchange. (Petrobras Section 5.08; PIFCo Section 5.08)

 

 

 

 

We will furnish to the trustee within 90 days after the end of our fiscal year every year a written statement of certain of our officers that will either certify that, to the best of their knowledge, we are in compliance with the indenture and the debt securities or specify any default. In addition, we will notify the trustee within 15 days (or promptly in the case of certain bankruptcy-related events of default) after becoming aware of the occurrence of any event of default. (Petrobras Section 10.05; PIFCo Section 10.05)

 

Regarding the Trustee

 

We and some of our subsidiaries maintain banking relations with the trustee in the ordinary course of our business.

If an event of default occurs, or an event occurs that would be an event of default if the requirements for giving us default notice or our default having to exist for a specified period of time were disregarded, the trustee may be considered to have a conflicting interest with respect to the debt securities or the indenture for purposes of the Trust Indenture Act of 1939. In that case, the trustee may be required to resign as trustee under the applicable indenture and we would be required to appoint a successor trustee.

 

DESCRIPTION OF MANDATORY CONVERTIBLE SECURITIES

 

We may issue mandatorily convertible securities under which holders receive a specified number of our common shares or preferred shares at a future date or dates. The price per mandatory convertible security and the number of common shares or preferred shares, as the case may be, that holders receive at maturity may be fixed at the time mandatory convertible securities are issued or may be determined by reference to a specific formula set forth in the mandatory convertible security. The mandatory convertible securities also may require us to make periodic payments to the holders of the mandatory convertible securities, and such payments may be secured.

 

The applicable prospectus supplement will describe the material terms of the mandatory convertible securities. Reference will be made in the applicable prospectus supplement to the mandatory convertible securities, and, if applicable, collateral, depositary or custodial arrangements, relating to the mandatory convertible securities. Material U.S. and Brazilian federal income tax considerations applicable to the holders of the mandatory convertible securities will also be discussed in the applicable prospectus supplement.

 

DESCRIPTION OF WARRANTS

 

We may issue warrants to purchase our debt securities, preferred shares (which may be in the form of ADSs) or common shares (which may be in the form of ADSs). Warrants may be issued independently or together with any securities and may be attached to or separate from those securities. Each series of warrants will be issued under a separate warrant agreement to be entered into by us and a bank or trust company, as warrant agent, all as will be set forth in the applicable prospectus supplement.

 

Debt Warrants

 

The following briefly summarizes the material terms that will generally be included in a debt warrant agreement. However, we may include different terms in the debt warrant agreement for any particular series of debt warrants and such other terms and all pricing and related terms will be disclosed in the applicable prospectus supplement. You should read the particular terms of any debt warrants that are offered by us and the related debt warrant agreement which will be described in more detail in the applicable prospectus supplement. The prospectus supplement will also state whether any of the generalized provisions summarized below do not apply to the debt warrants being offered.

 

General

 

We may issue warrants for the purchase of our debt securities. As explained below, each debt warrant will entitle its holder to purchase debt securities at an exercise price set forth in, or to be determined as set forth in, the applicable prospectus supplement. Debt warrants may be issued separately or together with debt securities.

 

The debt warrants are to be issued under debt warrant agreements to be entered into by us and one or more banks or trust companies, as debt warrant agent, all as will be set forth in the applicable prospectus supplement. At or around the time of an offering of debt warrants, a form of debt warrant agreement, including a form of debt warrant certificate representing the debt warrants, reflecting the alternative provisions that may be included in the debt warrant agreements to be entered into with respect to particular offerings of debt warrants, will be filed by amendment as an exhibit to the registration statement of which this prospectus forms a part.

 

Terms of the debt warrants to be described in the prospectus supplement

 

The particular terms of each issue of debt warrants, the debt warrant agreement relating to such debt warrants and such debt warrant certificates representing debt warrants will be described in the applicable prospectus supplement. This description will include:

 

 

 

You may exchange your debt warrant certificates for new debt warrant certificates of different denominations but they must be exercisable for the same aggregate principal amount of debt securities. If your debt warrant certificates are in registered form, you may present them for registration of transfer at the corporate trust office of the debt warrant agent or any other office indicated in the applicable prospectus supplement. Except as otherwise indicated in a prospectus supplement, before the exercise of debt warrants, holders of debt warrants will not be entitled to payments of principal or any premium or interest on the debt securities that can be purchased upon such exercise, or to enforce any of the covenants in the indenture relating to the debt securities that may be purchased upon such exercise.

 

Exercise of debt warrants

 

Unless otherwise provided in the applicable prospectus supplement, each debt warrant will entitle the holder to purchase a principal amount of debt securities for cash at an exercise price in each case that will be set forth in, or to be determined as set forth in, the applicable prospectus supplement. Debt warrants may be exercised at any time up to the close of business on the expiration date specified in the applicable prospectus supplement. After the close of business on the expiration date or any later date to which we extend the expiration date, unexercised debt warrants will become void.

 

Debt warrants may be exercised as set forth in the prospectus supplement applicable to the particular debt warrants. Upon delivery of payment of the exercise price and the debt warrant certificate properly completed and duly executed at the corporate trust office of the debt warrant agent or any other office indicated in the applicable prospectus supplement, we will, as soon as practicable, forward the debt securities that can be purchased upon such exercise of the debt warrants to the person entitled to them. If fewer than all of the debt warrants represented by the debt warrant certificate are exercised, a new debt warrant certificate will be issued for the remaining unexercised debt warrants. Holders of debt warrants will be required to pay any tax or governmental charge that may be imposed in connection with transferring the underlying debt securities in connection with the exercise of the debt warrants.

 

 

 

 

Modification and waiver

 

There are three types of changes we can make to the debt warrant agreement and the debt warrants of any series.

 

Changes Requiring Your Approval.  First, there are changes that cannot be made to your debt warrants or the debt warrant agreement under which they were issued without your specific approval. These are the following types of changes:

 

 

 

Changes Requiring a Majority Vote.  The second type of change to the debt warrant agreement or debt warrants of any series is the kind that requires a vote of approval by the holders of not less than a majority in number of the then outstanding unexercised debt warrants of that series. This category includes all changes other than those listed above under “Changes Requiring Your Approval” or changes that would not adversely affect holders of debt warrants or debt securities in any material respect.

 

Changes Not Requiring Approval.  The third type of change does not require any vote or consent by the holders of debt warrant certificates. This type is limited to clarifications and other changes that would not adversely affect such holders in any material respect.

 

 

 

 

Merger, consolidation, sale or other dispositions

 

Unless otherwise indicated in a prospectus supplement, under the debt warrant agreement for each series of debt warrants, we may consolidate with, or sell, convey or lease all or substantially all of our assets to, or merge with or into, any other corporation or firm to the extent permitted by the indenture for the debt securities that can be purchased upon exercise of such debt warrants. If we consolidate with or merge into, or sell, lease or otherwise dispose of all or substantially all of our assets to, another corporation or firm, that corporation or firm must become legally responsible for our obligations under the debt warrant agreements and debt warrants. If we sell or lease substantially all of our assets, one way the other firm or company can become legally responsible for our obligations is by way of a full and unconditional guarantee of our obligations. If the other company becomes legally responsible by a means other than a guarantee, we will be relieved from all such obligations.

 

Enforceability of rights; governing law

 

The debt warrant agent will act solely as our agent in connection with the issuance and exercise of debt warrants and will not assume any obligation or relationship of agency or trust for or with any holder of a debt warrant certificate or any owner of a beneficial interest in debt warrants. The holders of debt warrant certificates, without the consent of the debt warrant agent, the trustee, the holder of any debt securities issued upon exercise of debt warrants or the holder of any other debt warrant certificates, may, on their own behalf and for their own benefit, enforce, and may institute and maintain any suit, action or proceeding against us to enforce, or otherwise in respect of, their rights to exercise debt warrants evidenced by their debt warrant certificates. Except as may otherwise be provided in the applicable prospectus supplement, each issue of debt warrants and the related debt warrant agreement will be governed by the laws of the State of New York.

 

Additional Terms of the PIFCo Debt Warrants

 

Debt securities to be issued by PIFCo under the debt warrants and the PIFCo debt warrant agreement will be effectively guaranteed by Petrobras through the operation of a standby purchase agreement or, in limited circumstances, a guarantee. See “Description of the Standby Purchase Agreements” and “Description of the Guarantees.”

 

Equity Warrants

 

The following briefly summarizes the material terms that will generally be included in an equity warrant agreement. However, we may include different terms in the equity warrant agreement for any particular series of equity warrants and such other terms and all pricing and related terms will be disclosed in the applicable prospectus supplement. You should read the particular terms of any equity warrants that are offered by us and the related equity

warrant agreement which will be described in more detail in the applicable prospectus supplement. The prospectus supplement will also state whether any of the general provisions summarized below do not apply to the equity warrants being offered.

 

General

 

We may issue warrants for the purchase of our equity securities (i.e., our common shares and preferred shares, which may be in the form of ADSs). As explained below, each equity warrant will entitle its holder to purchase equity securities at an exercise price set forth in, or to be determined as set forth in, the applicable prospectus supplement. Equity warrants may be issued separately or together with equity securities.

 

We may issue equity warrants in connection with preemptive rights of our shareholders in connection with any capital increase, and in those circumstances we may choose to issue equity warrants in uncertificated form to the extent permitted by Brazilian law. In addition, if any equity warrants are offered in connection with preemptive rights, we may exclude holders resident in the United States from that offering to the extent permitted by Brazilian law. Equity warrants (other than equity warrants issued in connection with preemptive rights) are to be issued under equity warrant agreements to be entered into by us and one or more banks or trust companies, as equity warrant agent, all as will be set forth in the applicable prospectus supplement. At or around the time of an offering of equity warrants, a form of equity warrant agreement, including a form of equity warrant certificate representing the equity warrants, reflecting the alternative provisions that may be included in the equity warrant agreements to be entered into with respect to particular offerings of equity warrants, will be filed by amendment as an exhibit to the registration statement of which this prospectus forms a part.

 

Terms of the equity warrants to be described in the prospectus supplement

 

The particular terms of each issue of equity warrants, the equity warrant agreement (if any) relating to such equity warrants and the equity warrant certificates (if any) representing such equity warrants will be described in the applicable prospectus supplement. This description will include:

 

 

You may exchange your equity warrant certificates for new equity warrant certificates of different denominations but they must be exercisable for the same aggregate principal amount of equity securities. If your equity warrant certificates are in registered form, you may present them for registration of transfer and exercise them at the

corporate trust office of the equity warrant agent or any other office indicated in the applicable prospectus supplement. Unless otherwise indicated in a prospectus supplement, before the exercise of equity warrants, holders of equity warrants will not be entitled to receive dividends or exercise voting rights with respect to the equity securities that can be purchased upon such exercise, to receive notice as shareholders with respect to any meeting of shareholders for the election of our directors or any other matter, or to exercise any rights whatsoever as a shareholder.

 

Unless the applicable prospectus supplement states otherwise, the exercise price payable and the number of common shares or preferred shares that can be purchased upon the exercise of each equity warrant (other than equity warrants issued in connection with preemptive rights) will be subject to adjustment in certain events, including the issuance of a stock dividend to holders of common shares or preferred shares or a stock split, reverse stock split, combination, subdivision or reclassification of common shares or preferred shares. Instead of adjusting the number of common shares or preferred shares that can be purchased upon exercise of each equity warrant, we may elect to adjust the number of equity warrants. No adjustments in the number of shares that can be purchased upon exercise of the equity warrants will be required until cumulative adjustments require an adjustment of at least 1% of those shares. We may, at our option, reduce the exercise price at any time. We will not issue fractional shares or ADSs upon exercise of equity warrants, but we will pay the cash value of any fractional shares otherwise issuable.

 

Notwithstanding the previous paragraph, if there is a consolidation, merger or sale or conveyance of substantially all of our property, the holder of each outstanding equity warrant will have the right to the kind and amount of shares and other securities and property (including cash) receivable by a holder of the number of common shares or preferred shares into which that equity warrant was exercisable immediately prior to the consolidation, merger, sale or conveyance.

 

Exercise of equity warrants

 

Unless otherwise provided in the applicable prospectus supplement, each equity warrant will entitle the holder to purchase a number of equity securities for cash at an exercise price in each case that will be set forth in, or to be determined as set forth in, the prospectus supplement. Equity warrants may be exercised at any time up to the close of business on the expiration date specified in the applicable prospectus supplement. After the close of business on the expiration date or any later date to which we extend the expiration date, unexercised equity warrants will become void. Equity warrants for the purchase of preferred shares or common shares may be issued in the form of ADSs.

 

Equity warrants may be exercised as set forth in the prospectus supplement applicable to the particular equity warrants. Upon delivery of payment of the exercise price, delivery of the equity warrant certificate (if any) properly completed and duly executed at the corporate trust office of the equity warrant agent or any other office indicated in the applicable prospectus supplement and satisfaction of any other applicable requirements specified in the applicable prospectus supplement, we will, as soon as practicable, forward the equity securities that can be purchased upon such exercise of the equity warrants to the person entitled to them. If fewer than all of the equity warrants represented by the equity warrant certificate are exercised, a new equity warrant certificate will be issued for the remaining equity warrants. Holders of equity warrants will be required to pay any tax or governmental charge that may be imposed in connection with transferring the underlying equity securities in connection with the exercise of the equity warrants.

 

 

 

 

Modification and waiver

 

There are three types of changes we can make to the equity warrant agreement and the equity warrants of any series.

Changes Requiring Your Approval.  First, there are changes that cannot be made to your equity warrants or the equity warrant agreement under which they were issued without your specific approval. These are the following types of changes:

 

 

Changes Requiring a Majority Vote.  The second type of change to the equity warrant agreement or equity warrants of any series is the kind that requires a vote of approval by the holders of not less than a majority in number of the then outstanding unexercised equity warrants of that series. This category includes all changes other than those listed above under “— Changes Requiring Your Approval” or changes that would not adversely affect holders of equity warrants in any material respect.

 

Changes Not Requiring Approval.  The third type of change does not require any vote or consent by the holders of equity warrant certificates. This type is limited to clarifications, amendments, supplement and other changes that would not adversely affect such holders in any material respect.

 

 

 

 

Merger, consolidation, sale or other dispositions

 

Unless otherwise indicated in a prospectus supplement, under the equity warrant agreement for each series of equity warrants, we may consolidate with, or sell, convey or lease all or substantially all of our assets to, or merge with or into, any other corporation or firm to the extent permitted by the terms of the equity securities that can be purchased upon exercise of such equity warrants. If we consolidate with or merge into, or sell, lease or otherwise dispose of all or substantially all of our assets to, another corporation or firm, that corporation or firm must become legally responsible for our obligations under the equity warrant agreements and equity warrants and we will be relieved from all such obligations.

 

Enforceability of rights; governing law

 

The equity warrant agent will act solely as our agent in connection with the issuance and exercise of equity warrants and will not assume any obligation or relationship of agency or trust for or with any holder of an equity warrant certificate or any owner of a beneficial interest in equity warrants. The holders of equity warrant certificates, without the consent of the equity warrant agent, the holder of any equity securities issued upon exercise of equity warrants or the holder of any other equity warrant certificates, may, on their own behalf and for their own benefit, enforce, and may institute and maintain any suit, action or proceeding against us to enforce, or otherwise in respect of, their rights to exercise equity warrants evidenced by their equity warrant certificates. Except as may otherwise be provided in the applicable prospectus supplement, each issue of equity warrants and the related equity warrant agreement will be governed by the laws of the State of New York.

 

DESCRIPTION OF THE STANDBY PURCHASE AGREEMENTS

 

The following summary describes the material provisions of the standby purchase agreement. You should read the more detailed provisions of the applicable standby purchase agreement, including the defined terms, for provisions that may be important to you. This summary is subject to, and qualified in its entirety by reference to, the provisions of such standby purchase agreement.

 

General

 

In connection with the execution and delivery of a supplemental indenture, Petrobras will enter into a standby purchase agreement with the trustee for the benefit of the noteholders. The standby purchase agreement will provide that, in the event of a nonpayment of principal, interest and other amounts on the notes, Petrobras will be required to purchase the noteholders’ rights to receive those payments on the terms and conditions described below. The applicable supplemental indenture will provide that the standby purchase agreement will be considered part of the indenture. As a result, the holders of the notes will have the benefit of the standby purchase agreement. The standby purchase agreement is designed to function in a manner similar to a guarantee and obligates Petrobras to make the payments under debt securities or debt warrants.

 

Despite the Brazilian government’s ownership interest in Petrobras, the Brazilian government is not responsible in any manner for PIFCO’s obligations under the debt securities or debt warrants and Petrobras’ obligations under the standby purchase agreement.

 

Ranking

 

The obligations of Petrobras under the standby purchase agreement will constitute general unsecured obligations of Petrobras which at all times will rank pari passu with all other senior unsecured obligations of Petrobras that are not, by their terms, expressly subordinated in right of payment to the obligations of Petrobras under the standby purchase agreement.

 

Purchase Obligations

 

Partial purchase payment

 

In the event that, prior to the maturity date of the debt securities or debt warrants, PIFCo fails to make any payment on the debt securities or debt warrants on the date that payment is due under the terms of the debt securities or debt warrants and the indenture (which we refer to as the “partial non-payment due date”), other than in the case of an acceleration of that payment in accordance with the indenture:

 

 

To the extent that Petrobras fails to pay the partial non-payment amount immediately when required, Petrobras will be obligated to pay, in addition to that amount, interest on that amount at the default rate from the partial non-payment due date to and including the actual date of payment by Petrobras. We refer to this interest as the “partial non-payment overdue interest” and, together with the partial non-payment amount, as the “partial non-payment amount with interest.”

 

Payment of the partial non-payment amount with interest will be in exchange for the purchase by Petrobras of the rights of the noteholders to receive that amount from PIFCo. The noteholders will have no right to retain those rights, and, following the purchase and sale described above, the debt securities or debt warrants will remain outstanding with all amounts due in respect of the debt securities or debt warrants adjusted to reflect the purchase, sale and payment described above. Upon any such payment, Petrobras will be subrogated to the noteholders to the extent of any such payment.

The obligation of Petrobras to pay the partial non-payment amount with interest will be absolute and unconditional upon failure of PIFCo to make, prior to the maturity date of the debt securities or debt warrants, any payment on the debt securities or debt warrants on the date any such payment is due. All amounts payable by Petrobras under the standby purchase agreement in respect of any partial non-payment amount with interest will be payable in U.S. Dollars and in immediately available funds to the trustee. Petrobras will not be relieved of its obligations under the standby purchase agreement unless and until the trustee indefeasibly receives all amounts required to be paid by Petrobras under the standby purchase agreement (and any related event of default under the indenture has been cured), including payment of the partial nonpayment overdue interest as described in this prospectus supplement.

 

Total purchase payment

 

In the event that, at the maturity date of the debt securities or debt warrants (including upon any acceleration of the maturity date in accordance with the terms of the indenture), PIFCo fails to make any payment on the debt securities or debt warrants on the date that payment is due (which we refer to as the “total non-payment due date”),

 

 

To the extent that Petrobras fails to pay the total non-payment amount immediately when required, Petrobras will be obligated to pay, in addition to that amount, interest on that amount at the default rate from the total non-payment due date to and including the actual date of payment by Petrobras. We refer to this interest as the “total non-payment overdue interest” and, together with the total non-payment amount, as the “total non-payment amount with interest.”

 

Payment of the total non-payment amount with interest by Petrobras will be in exchange for the purchase by Petrobras of the rights of the noteholders to receive that amount from PIFCo. The noteholders will have no right to retain those rights, and, following the purchase and sale described above, Petrobras will be subrogated to the noteholders to the extent of any such payment.

 

The obligation of Petrobras to pay the total non-payment amount with interest will be absolute and unconditional upon failure of PIFCo to make, at the maturity date of the debt securities or debt warrants, or earlier upon any acceleration of the debt securities or debt warrants in accordance with the terms of the indenture, any payment in respect of principal, interest or other amounts due under the indenture and the debt securities or debt warrants on the date any such payment is due. All amounts payable by Petrobras under the standby purchase agreement in respect of any total nonpayment amount with interest will be payable in U.S. Dollars and in immediately available funds to the trustee. Petrobras will not be relieved of its obligations under the standby purchase agreement unless and until the trustee receives all amounts required to be paid by Petrobras under the standby purchase agreement (and any related event of default under the indenture has been cured), including payment of the total non-payment overdue interest.

 

Covenants

 

For so long as any of the debt securities or debt warrants are outstanding and Petrobras has obligations under the standby purchase agreement, Petrobras will, and will cause each of its subsidiaries to, comply with the terms of the covenants set forth below:

 

Ranking

 

Petrobras will ensure at all times that its obligations under the standby purchase agreement will be its general senior unsecured and unsubordinated obligations and will rank pari passu, without any preferences among themselves, with all other present and future senior unsecured and unsubordinated obligations 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 standby purchase agreement.

Notice of certain events

 

Petrobras will give notice to the trustee, as soon as is practicable and in any event within ten calendar days after Petrobras becomes aware, or should reasonably become aware, of the occurrence of any event of default or a default under the indenture, accompanied by a certificate of Petrobras setting forth the details of that event of default or default and stating what action Petrobras proposes to take with respect to it.

 

Limitation on consolidation, merger, sale or conveyance

 

Petrobras will not, in one or a series of transactions, consolidate or 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 (other than a direct or indirect subsidiary of Petrobras) or permit any person (other than a direct or indirect subsidiary of Petrobras) to merge with or into it unless:

 

 

Notwithstanding anything to the contrary in the foregoing, so long as no default or event of default under the indenture or the debt securities or debt warrants has occurred and is continuing at the time of such proposed transaction or would result from it:

 

 

 

Negative pledge

 

So long as any note remains outstanding, Petrobras will not create or permit any lien, other than a Petrobras permitted lien, on any of its assets to secure (i) any of its indebtedness or (ii) the indebtedness of any other person, unless Petrobras contemporaneously creates or permits the lien to secure equally and ratably its obligations under the standby purchase agreement or Petrobras provides other security for its obligations under the standby purchase agreement as is duly approved by a resolution of the noteholders in accordance with the indenture. In addition, Petrobras will not allow any of its subsidiaries to create or permit any lien, other than a Petrobras permitted lien, on any of Petrobras’ assets to secure (i) any of its indebtedness, (ii) any of the subsidiary’s indebtedness or (iii) the indebtedness of any other person, unless Petrobras contemporaneously creates or permits the lien to secure equally and ratably Petrobras’ obligations under the standby purchase agreement or Petrobras provides such other security for its obligations under the standby purchase agreement as is duly approved by a resolution of the noteholders in accordance with the indenture.

 

As used in this “Negative Pledge” section, the following terms have the respective meanings set forth below:

 

A “guarantee” means an obligation of a person to pay the indebtedness of another person including without limitation:

 

 

“Indebtedness” means any obligation (whether present or future, actual or contingent and including, without limitation, any guarantee) for the payment or repayment of money which has been borrowed or raised (including money raised by acceptances and all leases which, under generally accepted accounting principles in the country of incorporation of the relevant obligor, would constitute a capital lease obligation).

 

A “lien” means any mortgage, pledge, lien, hypothecation, security interest or other charge or encumbrance on any property or asset including, without limitation, any equivalent created or arising under applicable law.

 

A “project financing” of any project means the incurrence of indebtedness relating to the exploration, development, expansion, renovation, upgrade or other modification or construction of such project pursuant to which the providers of such indebtedness or any trustee or other intermediary on their behalf or beneficiaries designated by any such provider, trustee or other intermediary are granted security over one or more qualifying assets relating to such project for repayment of principal, premium and interest or any other amount in respect of such indebtedness.

(a) lien granted in respect of indebtedness owed to the Brazilian government, Banco Nacional de Desenvolvimento Econômico e Social or any official government agency or department of Brazil or of any state or region of Brazil;

 

(b) lien arising by operation of law, such as merchants’, maritime or other similar liens arising in Petrobras’ ordinary course of business or that of any subsidiary or lien in respect of taxes, assessments or other governmental charges that are not yet delinquent or that are being contested in good faith by appropriate proceedings;

(e) lien granted upon or with respect to any assets hereafter acquired by Petrobras or any subsidiary to secure the acquisition costs of those assets or to secure indebtedness incurred solely for the purpose of financing the acquisition of those assets, including any lien existing at the time of the acquisition of those assets, so long as the maximum amount so secured will not exceed the aggregate acquisition costs of all such assets or the aggregate indebtedness incurred solely for the acquisition of those assets, as the case may be;

 

(f) lien granted in connection with the indebtedness of a wholly-owned subsidiary owing to Petrobras or another wholly-owned subsidiary;

(l) lien granted or incurred to secure any extension, renewal, refinancing, refunding or exchange (or successive extensions, renewals, refinancings, refundings or exchanges), in whole or in part, of or for any indebtedness secured by any lien referred to in paragraphs (a) through (k) above (but not paragraph (d)), provided that such lien does not extend to any other property, the principal amount of the indebtedness secured by the lien is not increased, and in the case of paragraphs (a), (b), (c) and (f), the obligees meet the requirements of that paragraph, and in the case of paragraph (h), the indebtedness is incurred in connection with a project financing by Petrobras, any of Petrobras’ subsidiaries or any consortium or other venture in which Petrobras or any subsidiary have any ownership or other similar interest; and

A “wholly-owned subsidiary” means, with respect to any corporate entity, any person of which 100% of the outstanding capital stock (other than qualifying shares, if any) having by its terms ordinary voting power (not dependent on the happening of a contingency) to elect the board of directors (or equivalent controlling governing body) of that person is at the time owned or controlled directly or indirectly by that corporate entity, by one or more wholly-owned subsidiaries of that corporate entity or by that corporate entity and one or more wholly-owned subsidiaries.

 

Provision of financial statements and reports

 

Petrobras will provide to the trustee, in English or accompanied by a certified English translation thereof, (i) within 90 calendar days after the end of each fiscal quarter (other than the fourth quarter), its unaudited and consolidated balance sheet and statement of income calculated in accordance with U.S. GAAP, (ii) within 120 calendar days after the end of each fiscal year, its audited and consolidated balance sheet and statement of income calculated in accordance with U.S. GAAP and (iii) such other financial data as the trustee may reasonably request. Petrobras will provide, together with each of the financial statements delivered hereunder, an officers’ certificate stating that a review of Petrobras’ and PIFCo’s activities has been made during the period covered by such financial statements with a view to determining whether Petrobras and PIFCo have kept, observed, performed and fulfilled their covenants and agreements under the standby purchase agreement and the indenture, as applicable, and that no event of default has occurred during such period. In addition, whether or not Petrobras is required to file reports with the SEC, Petrobras will file with the SEC and deliver to the trustee (for redelivery to all holders of debt securities or debt warrants) all reports and other information it would be required to file with the SEC under the Exchange Act if it were subject to those regulations. If the SEC does not permit the filing described above, Petrobras will provide annual and interim reports and other information to the trustee within the same time periods that would be applicable if Petrobras were required and permitted to file these reports with the SEC.

 

Additional amounts

 

Except as provided below, Petrobras will make all payments of amounts due under the standby purchase agreement and each other document entered into in connection with the standby purchase agreement without withholding or deducting any present or future taxes, levies, deductions or other governmental charges of any nature imposed by Brazil, the jurisdiction of PIFCo’s incorporation or any other jurisdiction in which PIFCo appoints a paying agent under the indenture, or any political subdivision of such jurisdictions (the “taxing jurisdictions”). If Petrobras is required by law to withhold or deduct any taxes, levies, deductions or other governmental charges, Petrobras will make such deduction or withholding, make payment of the amount so withheld to the appropriate governmental authority and pay the noteholders any additional amounts necessary to ensure that they receive the same amount as they would have received without such withholding or deduction.

Petrobras will not, however, pay any additional amounts in connection with any tax, levy, deduction or other governmental charge that is imposed due to any of the following (“excluded additional amounts”):

 

 

Petrobras undertakes that, if European Council Directive 2003/48/EC or any other Directive implementing the conclusions of ECOFIN council meeting of November 26-27, 2000 is brought into effect, Petrobras will ensure that it maintains a paying agent in a member state of the European Union that will not be obliged to withhold or deduct tax pursuant to the Directive.

 

Petrobras will pay any stamp, administrative, excise or property taxes arising in a taxing jurisdiction in connection with the execution, delivery, enforcement or registration of the debt securities or debt warrants and will indemnify the noteholders for any such stamp, administrative, excise or property taxes paid by noteholders.

 

Events of Default

 

There are no events of default under the standby purchase agreement. The indenture, however, contains events of default relating to Petrobras that may trigger an event of default and acceleration of the debt securities or debt warrants. See “Description of Debt Securities — Default and Related Matters — Events of Default.” Upon any such acceleration (including any acceleration arising out of the insolvency or similar events relating to Petrobras), if

PIFCo fails to pay all amounts then due under the debt securities or debt warrants and the indenture, Petrobras will be obligated to make a total purchase payment as described above.

 

Amendments

 

The standby purchase agreement may only be amended or waived in accordance with its terms pursuant to a written document which has been duly executed and delivered by Petrobras and the trustee, acting on behalf of the holders of the debt securities or debt warrants. Because the standby purchase agreement forms part of the indenture, it may be amended by Petrobras and the trustee, in some cases without the consent of the holders of the debt securities or debt warrants.

 

Except as contemplated above, the indenture will provide that the trustee may execute and deliver any other amendment to the standby purchase agreement or grant any waiver thereof only with the consent of the noteholders of a majority in aggregate principal amount of the debt securities or debt warrants then outstanding.

 

Governing Law

 

The standby purchase agreement will be governed by the laws of the State of New York.

 

Jurisdiction

 

Petrobras has consented to the non-exclusive jurisdiction of any court of the State of New York or any U.S. federal court sitting in the Borough of Manhattan, The City of New York, New York, United States and any appellate court from any thereof. Service of process in any action or proceeding brought in such New York State federal court sitting in New York City may be served upon Petrobras at Petrobras’ New York office. The standby purchase agreement provides that if Petrobras no longer maintains an office in New York City, then it will appoint a replacement process agent within New York City as its authorized agent upon which process may be served in any action or proceeding.

 

Waiver of Immunities

 

To the extent that Petrobras may in any jurisdiction claim for itself or its assets immunity from a suit, execution, attachment, whether in aid of execution, before judgment or otherwise, or other legal process in connection with the standby purchase agreement (or any document delivered pursuant thereto) and to the extent that in any jurisdiction there may be immunity attributed to Petrobras, PIFCo or their assets, whether or not claimed, Petrobras has irrevocably agreed with the trustee, for the benefit of the noteholders, not to claim, and to irrevocably waive, the immunity to the full extent permitted by law.

 

Currency Rate Indemnity

 

Petrobras has agreed that, if a judgment or order made by any court for the payment of any amount in respect of any of its obligations under the standby purchase agreement is expressed in a currency (the “judgment currency”) other than U.S. Dollars (the “denomination currency”), Petrobras will indemnify the trustee, on behalf of the noteholders, against any deficiency arising from any variation in rates of exchange between the date as of which the denomination currency is notionally converted into the judgment currency for the purposes of the judgment or order and the date of actual payment. This indemnity will constitute a separate and independent obligation from Petrobras’ other obligations under the standby purchase agreement, will give rise to a separate and independent cause of action, will apply irrespective of any indulgence granted from time to time and will continue in full force and effect.

 

DESCRIPTION OF THE GUARANTEES

 

The following description of the terms and provisions of the guarantees summarizes the general terms that will apply to each guarantee that we deliver in connection with an issuance of debt securities or debt warrants by PIFCo. When PIFCo sells a series of its debt securities or debt warrants, Petrobras may, in limited circumstances, execute

and deliver a guarantee of that series of debt securities or debt warrants under a guarantee agreement for the benefit of the holders of that series of debt securities or debt warrants.

 

Pursuant to any guarantee, Petrobras will agree, from time to time upon the receipt of notice from the trustee that PIFCo has failed to make the required payments under a series of debt securities and the PIFCo indenture or under the debt warrants and the PIFCo debt warrant agreement, to indemnify you for unpaid claims against PIFCo, whether those claims are in respect of principal, interest or any other amounts. The amount to be paid by Petrobras under the guarantee will be an amount equal to the amount of those claims plus interest thereon from the date PIFCo was otherwise obligated to make its payments under the PIFCo indenture to the date Petrobras actually makes payment under the guarantee. Petrobras will be obligated to make these payments by the expiration of any applicable grace periods under the PIFCo indenture. Petrobras may defer its obligation under the guarantee to make payments under certain circumstances described in the applicable prospectus supplement.

 

Only one guarantee will be issued by Petrobras in connection with the issuance of a series of debt securities or debt warrants by PIFCo. Each guarantee agreement will be qualified as an indenture under the Trust Indenture Act of 1939. Unless the applicable prospectus supplement states otherwise, The Bank of New York will act as guarantee trustee under each guarantee agreement.

 

The description of the applicable guarantee in the prospectus supplement will summarize the material provisions thereof and reference will be made to the guarantee agreement.

 

DESCRIPTION OF AMERICAN DEPOSITARY RECEIPTS

 

General

 

Citibank, NA. has agreed to act as the depositary for the American depositary shares. Citibank’s depositary offices are located at 388 Greenwich Street, New York, New York 10013. American depositary shares are frequently referred to as ADSs and represent ownership interests in securities that are on deposit with the depositary. ADSs are normally represented by certificates that are commonly known as American depositary receipts or ADRs. The depositary has appointed a custodian to safekeep the securities on deposit. In this case, the custodian is Câmara de Liquidação e Custódia do Rio do Janeiro, located at Praça XV de Novembro, 20 — 7th floor — Rio de Janeiro — RJ 20010-010, Brazil.

 

Petrobras appointed Citibank as depositary under the terms of an amended and restated deposit agreement for the common shares, dated July 14, 2000, as amended by Amendment No. 1, dated July 27, 2000, as amended by Amendment No. 2, dated March 23, 2001 and as amended by Amendment No. 3 dated September 1, 2005, to the amended and restated deposit agreement. Petrobras appointed Citibank as depositary under the terms of an amended and restated deposit agreement for the preferred shares, dated February 21, 2001, as amended by Amendment No. 1, dated March 23, 2001 and as amended by Amendment No. 2 dated September 1, 2005, to the amended and restated deposit agreement. A copy of each of these agreements is on file with the Securities and Exchange Commission under cover of a registration statement on Form F-6. You may obtain a copy of each such agreement from the Securities and Exchange Commission’s Public Reference Room. See “Where You Can Find Additional Information.” Please refer to Registration Number 333-12298 for the common shares deposit agreement; to Registration Number 333-13168 for the amended and restated deposit agreement; and to Registration Number 333-13660 for Amendment No. 1 to the amended and restated deposit agreement, when retrieving your copy.

 

Petrobras is providing you with a summary description of the material terms of the ADSs and of your material rights as an owner of ADSs. Your rights and obligations as an owner of ADSs will be determined by reference to the terms of the applicable deposit agreement and not by this summary. This summary is not intended as a substitute for the applicable deposit agreement. Petrobras urges you to review the applicable deposit agreement in its entirety.

 

Each ADS represents four of Petrobras’ preferred shares or common shares on deposit with the custodian. An ADS will also represent any other property received by the depositary or the custodian on behalf of the owner of the ADS but that has not been distributed to the owners of ADSs because of legal restrictions or practical considerations.

 

If you become an owner of ADSs, you will become a party to the applicable deposit agreement and therefore will be bound by its terms and to the terms of the ADR that represents your ADSs. The applicable deposit agreement and the ADR specify Petrobras’ rights and obligations as well as your rights and obligations and those of the depositary. As an ADS holder you have agreed to appoint the depositary to act on your behalf in certain circumstances. The deposit agreements and the ADRs are governed by New York law. However, Petrobras’ obligations to the holders of the preferred shares and common shares will continue to be governed by the laws of Brazil, which may be different from the laws in the United States.

 

As an owner of ADSs, your ADSs may be represented either by an ADR registered in your name or through a brokerage or safekeeping account. If you decide to hold your ADSs through your brokerage or safekeeping account, you must rely on the procedures of your broker or bank to assert your rights as an ADS owner. Please consult with your broker or bank to determine what those procedures are. This summary description assumes you have opted to own the ADSs directly by means of an ADR registered in your name and, as such, Petrobras will refer to you as the “holder.” When Petrobras refers to “you,” Petrobras assumes the reader owns ADSs and will own ADSs at the relevant time.

 

Dividends and distributions

 

As a holder, you will generally have the right to receive the distributions Petrobras makes on the securities deposited with the custodian bank. Your receipt of these distributions may be limited, however, by practical

considerations and legal limitations. You will receive distributions under the terms of the applicable deposit agreement in proportion to the number of ADSs held as of a specified record date.

 

Distributions of Cash.  Whenever Petrobras makes a cash distribution for the securities on deposit with the custodian, it will notify the depositary. Upon receipt of that notice the depositary will arrange for the funds to be converted into U.S. dollars and for the distribution of the U.S. dollars to the holders, subject to Brazilian laws and regulations.

 

The conversion into U.S. dollars will take place only if practicable and if the U.S. dollars are transferable to the United States. The depositary will reduce the distribution of cash to holders by applicable fees, expenses, taxes and governmental charges payable by holders under the terms of the applicable deposit agreement. The depositary will apply the same method for distributing the proceeds of the sale of any property (such as undistributed rights) held by the custodian in respect of securities on deposit.

 

Distributions of Shares.  Whenever Petrobras makes a distribution consisting of a dividend and a free distribution of preferred shares or common shares on securities on deposit with the custodian, it will notify the depositary and deposit the applicable number of preferred shares or common shares with the custodian. Upon receipt of notice of such deposit the depositary will either distribute to holders new ADSs representing the aggregate preferred shares or common shares deposited or modify the ratio of ADSs to preferred shares or common shares, in which case each ADS you already hold will represent rights and interests in the additional preferred shares or common shares deposited. Only whole new ADSs will be distributed. Fractional entitlements will be sold and the proceeds of the sale will be distributed to holders as in the case of a cash distribution described above.

 

The distribution of new ADSs or the modification of the ADS-to-share ratio upon a distribution of preferred shares or common shares will be reduced by applicable fees, expenses, taxes and governmental charges payable by holders under the terms of the deposit agreement. In order to pay the taxes or governmental charges, the depositary may sell all or a portion of the new preferred shares or common shares so distributed.

 

No distribution of new ADSs as described above will be made if it would violate the U.S. securities laws, or any other law, or if it is not operationally practicable. If the depositary does not distribute new ADSs as described above, it will use its best efforts to sell the preferred shares or common shares received and will distribute the proceeds of the sale as in the case of a distribution of cash.

 

Distributions of Rights.  If Petrobras distributes rights to subscribe for additional preferred shares or common shares, it will give at least 60 days prior notice to the depositary and it will assist the depositary in determining whether it is lawful and reasonably practicable to make these additional rights available to holders.

 

The depositary will establish procedures for the distribution of rights to purchase additional ADSs to holders and to enable holders to exercise rights when lawful and reasonably practicable. You may have to pay fees, expenses, taxes and other governmental charges to subscribe for the new ADSs upon the exercise of your right. The depositary is not obligated to make available to holders of rights a method to exercise rights to subscribe to preferred shares or common shares directly rather than American depositary shares.

 

The depositary will not distribute rights to you if:

 

 

The depositary will sell rights that are not exercised or distributed if the sale is lawful and reasonably practicable. The proceeds of the sale will be distributed to holders as in the case of a cash distribution described above. If the depositary is unable to sell the rights, it will allow the rights to lapse.

 

Elective Distribution.  If Petrobras distributes a dividend payable at the election of shareholders either in cash or in additional shares, it will give prior notice to the depositary and it will indicate whether it wishes the

elective distribution to be made available to you. In this case, Petrobras will assist the depositary in determining whether the distribution is lawful and reasonably practicable.

 

The depositary will make the election available to you only if it is reasonably practical and if Petrobras has provided all of the documentation contemplated in the applicable deposit agreement. In this case, the depositary will establish procedures to enable you to elect to receive either cash or additional ADSs, in each case, as described in the applicable deposit agreement.

 

If the election is not made available to you, you will receive either cash or additional ADSs, depending on what a shareholder in Brazil would receive upon failing to make an election, as described more fully in the applicable deposit agreement.

 

Other Distributions.  Petrobras distributes property other than cash, preferred shares, rights to purchase preferred shares, common shares or rights to purchase additional common shares, it will notify the depositary in advance and will indicate whether it wishes the distribution to be made to you. If so, Petrobras will assist the depositary in determining whether the distribution to holders is lawful and reasonably practicable.

 

If it is reasonably practicable to distribute the property to you and if Petrobras provides all of the documentation contemplated in the applicable deposit agreement, the depositary will distribute the property to the holders in a manner it deems practicable.

 

The distribution will be reduced by any applicable fees, expenses, taxes and governmental charges payable by holders under the terms of the applicable deposit agreement. In order to pay the taxes and governmental charges, the depositary may sell all or a portion of the property received.

 

The depositary will not distribute the property to you and will sell the property if:

 

 

The proceeds of the sale will be distributed to holders as in the case of a cash distribution as described above.

 

Redemption

 

If Petrobras decides to redeem any of the securities on deposit with the custodian, it will notify the depositary at least 60 days prior to the date of redemption. If it is reasonably practicable and if Petrobras provides all of the documentation contemplated in the applicable deposit agreement, the depositary will provide the holder with notice of the proposed redemption.

 

The custodian will be instructed to surrender the shares being redeemed against payment of the applicable redemption price. After the redemption has taken place, the depositary will convert, transfer and distribute the proceeds, reduced by any applicable fees, expenses, taxes and other government charges. The depositary will then retire the ADSs and cancel the ADRs. If less than all of the outstanding ADSs are being redeemed, the ADSs to be retired will be selected by lot or on a pro rata basis, as may be determined by the depositary.

 

Changes affecting the preferred shares and common shares

 

The preferred shares or common shares held on deposit for your ADSs may be affected by changes from time to time. For example, there may be a change in nominal or par value, a split-up, cancellation, consolidation or reclassification of such preferred shares or common shares or a recapitalization, reorganization, merger, consolidation or sale of assets.

 

If a change were to occur, your ADSs would, to the extent permitted by law, represent the right to receive the property received or exchanged in respect of the preferred shares or common shares, as applicable, held on deposit. The depositary may in those circumstances deliver new ADSs to you or call for the exchange of your existing ADSs

for new ADSs. If the depositary may not lawfully distribute such property to you, the depositary may sell the property and distribute the net proceeds to you as in the case of a cash distribution as described above.

 

Issuance of ADSs upon Deposit of preferred shares or common shares

 

The depositary may create ADSs on your behalf if you or your broker deposits preferred shares or common shares with the custodian. The depositary will deliver these ADSs to the person you indicate only after you pay any applicable issuance fees and any charges and taxes payable for the transfer of the preferred shares or common shares, as applicable, to the custodian. Your ability to deposit preferred shares or common shares and receive ADSs may be limited by U.S. and Brazilian legal considerations applicable at the time of deposit.

 

The issuance of ADSs may be delayed until the depositary or the custodian receives confirmation that all required approvals have been given and that the preferred shares or common shares, as applicable, have been duly transferred to the custodian. The depositary will only issue ADSs in whole numbers.

 

When you make a deposit of preferred shares or common shares, you will be responsible for transferring good and valid title to the depositary. As such, you will be deemed to represent and warrant that:

 

 

If any of the representations or warranties, are incorrect in any way, Petrobras and the depositary may, at your cost and expense, take any and all actions necessary to correct the consequences of the misrepresentations.

 

Withdrawal of shares upon cancellation of ADSs

 

As a holder, you will be entitled to present your ADSs to the depositary, at the custodian’s offices, for cancellation and receive the corresponding number of underlying preferred shares or common shares, as applicable. Your ability to withdraw the preferred shares or common shares, as applicable, may be limited by U.S. and Brazilian law applicable at the time of withdrawal. In order to withdraw the preferred shares or common shares represented by your ADSs, you will be required to pay to the depositary the fees for cancellation of ADSs and any charges and taxes payable upon the transfer of the preferred shares or common shares being withdrawn. You assume the risk of delivery of all funds and securities upon withdrawal. Once canceled, the ADSs will not have any rights under the applicable deposit agreement.

 

If you hold an ADR registered in your name, the depositary may ask you to provide proof of identity and genuineness of any signature and such other documents as the depositary may deem appropriate before it will cancel your ADSs. The withdrawal of the preferred shares or common shares represented by your ADSs may be delayed until the depositary receives satisfactory evidence of compliance with all applicable laws and regulations. The depositary will only accept ADSs for cancellation that represent a whole number of securities on deposit.

 

You will have the right to withdraw the securities represented by your ADSs at any time unless any of these conditions exist:

 

 

 

The applicable deposit agreement may not be modified to impair your right to withdraw the securities represented by your ADSs except to comply with mandatory provisions of law.

 

Voting rights

 

According to Petrobras’ charter, preferred shares do not entitle the holder to vote except as provided by Brazilian law under limited circumstances, including upon default in the payment of dividends for three consecutive years. A holder of an ADS representing a common share will generally have the right under the applicable deposit agreement to instruct the depositary to exercise the voting rights for the common shares represented by your ADSs. The voting rights of holders of preferred shares and common shares are described in “Item 10. Memorandum and Articles of Association of Incorporation — Voting Rights” in the annual report on Form 20-F of Petrobras for the year ended December 31, 2005, which is incorporated by reference in this prospectus.

 

At Petrobras request, the depositary will distribute to you any notice of shareholders’ meeting received from Petrobras, together with information explaining how to instruct the depositary to exercise your voting rights on the securities represented by ADSs.

 

If the depositary timely receives voting instructions from a holder of ADSs, it will endeavor to vote the securities represented by the holder’s ADSs in accordance with the voting instructions.

 

The ability of the depositary to carry out voting instructions may be limited by practical and legal limitations and the terms of the securities on deposit. Petrobras cannot assure you that you will receive voting materials in time to enable you to return voting instructions to the depositary in a timely manner.

 

Fees and charges

 

As an ADS holder, you will be required to pay the following service fees to the depositary:

 

 

As an ADS holder you will also be responsible for paying some of the fees and expenses incurred by the depositary and certain taxes and governmental charges, including:

 

 

Petrobras has agreed to pay certain other charges and expenses of the depositary, however, it will not pay or be liable for fees or related charges with respect to shares or ADSs. The fees and charges you may be required to pay

may vary over time and may be changed by Petrobras and by the depositary. You will receive prior notice of any changes in the amount you may be required to pay.

 

Amendments and termination

 

Petrobras may agree with the depositary to modify any applicable deposit agreement at any time without your consent. Any amendment which will increase any fees or charges or which will otherwise materially prejudice an existing right you may have will not become effective until 30 days after notice of the amendment is given to the holders. Petrobras will not deem any modifications or supplements that are reasonably necessary for the ADSs to be registered under the Securities Act of 1933 or to be traded solely in electronic book-entry form, and which do not impose or increase the fees and charges you are required to pay, to be materially prejudicial to your substantive rights. In addition, Petrobras may not be able to provide you with prior notice of any modifications or supplements that are required to comply with applicable provisions of law.

 

You will be bound by the modifications to the applicable deposit agreement if you continue to hold your ADSs after the modifications to the applicable deposit agreement become effective. Except as permitted by law, the applicable deposit agreement cannot be amended so as to prevent you from withdrawing the preferred shares or common shares represented by your ADSs.

 

Petrobras has the right to direct the depositary to terminate the applicable deposit agreement. Similarly, the depositary may terminate the applicable deposit agreement. In either case, the depositary must give notice to the holders at least 30 days before termination.

 

For a period of six months after termination of the applicable deposit agreement, you will be able to request the cancellation of your ADSs and the withdrawal of the preferred shares or common shares represented by your ADSs and the delivery of all other property held by the depositary in respect of those preferred shares or common shares on the same terms as prior to the termination. During this six month period, the depositary will continue to collect all distributions received on the preferred shares or common shares on deposit but will not distribute anything to you until you request the cancellation of your ADSs.

 

After the expiration of the six month period, the depositary may sell the securities held on deposit. The depositary will hold the proceeds from the sale and any other cash then held for the holders of ADSs in a non-interest bearing, unsegregated account. After making the sale, the depositary will have no further obligations to holders under the applicable deposit agreement, other than to account for the net proceeds and other cash then held for the holders of ADSs still outstanding.

 

Books of depositary

 

The depositary will maintain ADS holder records at its depositary office. You may inspect these records at its office during regular business hours; provided, however, that the inspection will not be carried out for the purpose of communicating with holders of ADRs in the interest of a business or object other than Petrobras’ business or other than a matter related to the applicable deposit agreement or ADRs.

 

The depositary will maintain an office and facilities in New York to record and process the issuance, cancellation, combination, split-up and transfer of ADRs. These facilities may be closed from time to time, to the extent not prohibited by law.

 

Limitations on obligations and liabilities

 

The deposit agreements limit Petrobras’ obligations and the depositary’s obligations to you as follows:

 

 

 

Pre-Release transactions

 

The depositary may, in some circumstances, issue ADSs before receiving a deposit of preferred shares or common shares or release preferred shares or common shares before receiving ADSs. These transactions are commonly referred to as “pre-release transactions.” The deposit agreements limit the aggregate size of pre-release transactions and impose a number of conditions on these types of transactions such as:

 

 

The depositary may retain for its own account the compensation received from the pre-release transactions.

 

You will be responsible for the taxes and other governmental charges payable on the ADSs and the securities represented by the ADSs. Petrobras, the depositary, and the custodian may deduct the taxes and governmental charges payable by holders from any distribution and may sell any and all property on deposit to pay the taxes and governmental charges payable by holders. You will be liable for any deficiency if the sale proceeds do not cover the taxes that are due.

 

The depositary may refuse to issue ADSs, to deliver, transfer, split and combine ADRs or to release securities on deposit until all taxes and charges are paid by the applicable holder. The depositary and the custodian may take reasonable administrative actions to obtain tax refunds and reduced tax withholding for any distributions on your behalf. However, you may be required to provide to the depositary and to the custodian proof of taxpayer status and residence and other information as the depositary and the custodian may require to fulfill their legal obligations. Under the applicable deposit agreement, you will be required to indemnify Petrobras, the depositary, and the custodian for any claims with respect to taxes based on any tax benefit obtained for you.

Foreign currency conversion

 

The depositary will arrange for the conversion of all foreign currency received into U.S. dollars if the conversion can be performed on a practicable basis or by sale, and it will distribute the U.S. dollars in accordance with the terms of the applicable deposit agreement. You may have to pay any fees and expenses incurred in converting foreign currency, such as fees and expenses incurred in complying with currency exchange controls and other governmental requirements.

 

If the conversion of foreign currency is not practical or lawful, or if any required approvals are denied or not obtainable at a reasonable cost or within a reasonable period, the depositary may take the following actions in its discretion:

Global Securities

 

Unless otherwise specified in the applicable prospectus supplement, the following information relates to the form, clearing and settlement of U.S. dollar-denominated debt securities.

 

We will issue the securities in global form, without interest coupons. Securities issued in global form will be represented, at least initially, by one or more global debt securities. Upon issuance, global securities will be deposited with the trustee as custodian for The Depository Trust Company, known as DTC, and registered in the name of Cede & Co., as nominee of DTC. Ownership of beneficial interests in each global security will be limited to persons who have accounts with DTC, whom we refer to as DTC participants, or persons who hold interests through DTC participants. We expect that, under procedures established by DTC, ownership of beneficial interests in each global security will be shown on, and transfer of ownership of those interests will be effected only through, records maintained by DTC (with respect to interests of DTC participants) and the records of DTC participants (with respect to other owners of beneficial interests in the global securities).

 

Beneficial interests in the global securities may be credited within DTC to Euroclear Bank S.A./N.V. and Clearstream, Luxembourg Banking, société anonyme on behalf of the owners of such interests. We refer to Euroclear S.A./N.V. and Clearstream, Luxembourg Banking, société anonyme as “Euroclear” and “Clearstream, Luxembourg,” respectively.

 

Investors may hold their interests in the global securities directly through DTC, Euroclear or Clearstream, Luxembourg, if they are participants in those systems, or indirectly through organizations that are participants in those systems.

 

Beneficial interests in the global securities may not be exchanged for securities in physical, certificated form except in the limited circumstances described below.

 

Book-entry procedures for global securities

 

Interests in the global securities will be subject to the operations and procedures of DTC, Euroclear and Clearstream, Luxembourg. We provide the following summaries of those operations and procedures solely for the convenience of investors. The operations and procedures of each settlement system are controlled by that settlement system and may be changed at any time. We are not responsible for those operations or procedures.

 

DTC has advised that it is:

 

 

DTC was created to hold securities for its participants and to facilitate the clearance and settlement of securities transactions between its participants through electronic book-entry changes to the accounts of its participants. DTC’s participants include securities brokers and dealers; banks and trust companies; clearing corporations; and certain other organizations. Indirect access to DTC’s system is also available to others such as banks, brokers, dealers and trust companies; these indirect participants clear through or maintain a custodial relationship with a DTC participant, either directly or indirectly. Investors who are not DTC participants may beneficially own securities held by or on behalf of DTC only through DTC participants or indirect participants in DTC.

So long as DTC or its nominee is the registered owner of a global security, DTC or its nominee will be considered the sole owner or holder of the securities represented by that global security for all purposes under the indenture. Except as provided below, owners of beneficial interests in a global security:

 

 

As a result, each investor who owns a beneficial interest in a global security must rely on the procedures of DTC to exercise any rights of a holder of securities under the indenture (and, if the investor is not a participant or an indirect participant in DTC, on the procedures of the DTC participant through which the investor owns its interest).

 

Payments of principal, premium, if any, and interest with respect to the securities represented by a global security will be made by the trustee to DTC’s nominee as the registered holder of the global security. Neither we nor the trustee will have any responsibility or liability for the payment of amounts to owners of beneficial interests in a global security, for any aspect of the records relating to or payments made on account of those interests by DTC, or for maintaining, supervising or reviewing any records of DTC relating to those interests.

 

Payments by participants and indirect participants in DTC to the owners of beneficial interests in a global security will be governed by standing instructions and customary practices and will be the responsibility of those participants or indirect participants and not of DTC, its nominee or us.

 

Transfers between participants in DTC will be effected under DTC’s procedures and will be settled in same-day funds. Transfers between participants in Euroclear or Clearstream, Luxembourg will be effected in the ordinary way under the rules and operating procedures of those systems.

 

Cross-market transfers between DTC participants, on the one hand, and Euroclear or Clearstream, Luxembourg participants, on the other hand, will be effected within DTC through the DTC participants that are acting as depositaries for Euroclear and Clearstream, Luxembourg. To deliver or receive an interest in a global security held in a Euroclear or Clearstream, Luxembourg account, an investor must send transfer instructions to Euroclear or Clearstream, Luxembourg, as the case may be, under the rules and procedures of that system and within the established deadlines of that system. If the transaction meets its settlement requirements, Euroclear or Clearstream, Luxembourg, as the case may be, will send instructions to its DTC depositary to take action to effect final settlement by delivering or receiving interests in the relevant global securities in DTC, and making or receiving payment under normal procedures for same-day funds settlement applicable to DTC. Euroclear and Clearstream, Luxembourg participants may not deliver instructions directly to the DTC depositaries that are acting for Euroclear or Clearstream, Luxembourg.

 

Because of time zone differences, the securities account of a Euroclear or Clearstream, Luxembourg participant that purchases an interest in a global security from a DTC participant will be credited on the business day for Euroclear or Clearstream, Luxembourg immediately following the DTC settlement date. Cash received in Euroclear or Clearstream, Luxembourg from the sale of an interest in a global security to a DTC participant will be received with value on the DTC settlement date but will be available in the relevant Euroclear or Clearstream, Luxembourg cash account as of the business day for Euroclear or Clearstream, Luxembourg following the DTC settlement date.

 

DTC, Euroclear and Clearstream, Luxembourg have agreed to the above procedures to facilitate transfers of interests in the global securities among participants in those settlement systems. However, the settlement systems are not obligated to perform these procedures and may discontinue or change these procedures at any time. Neither we nor the trustee have any responsibility for the performance by DTC, Euroclear or Clearstream, Luxembourg or their participants or indirect participants of their obligations under the rules and procedures governing their operations.

Certificated securities

 

Beneficial interests in the global securities may not be exchanged for securities in physical, certificated form unless:

 

 

In all cases, certificated securities delivered in exchange for any global security will be registered in the names, and issued in any approved denominations, requested by the depository.

 

For information concerning paying agents for any securities in certificated form, see “Description of Debt Securities — Payment Provisions — Paying Agents.”

 

Clearstream, Luxembourg and Euroclear

 

Clearstream, Luxembourg has advised that: it is a duly licensed bank organized as a société anonyme incorporated under the laws of Luxembourg and is subject to regulation by the Luxembourg Commission for the supervision of the financial sector (Commission de surveillance du secteur financier); it holds securities for its customers and facilitates the clearance and settlement of securities transactions among them, and does so through electronic book-entry transfers between the accounts of its customers, thereby eliminating the need for physical movement of certificates; it provides other services to its customers, including safekeeping, administration, clearance and settlement of internationally traded securities and lending and borrowing of securities; it interfaces with the domestic markets in over 30 countries through established depositary and custodial relationships; its customers include worldwide securities brokers and dealers, banks, trust companies and clearing corporations and may include certain other professional financial intermediaries; its U.S. customers are limited to securities brokers and dealers and banks; and indirect access to the Clearstream, Luxembourg system is also available to others that clear through Clearstream, Luxembourg customers or that have custodial relationships with its customers, such as banks, brokers, dealers and trust companies.

 

Euroclear has advised that: it is incorporated under the laws of Belgium as a bank and is subject to regulation by the Belgian Banking and Finance Commission (Commission Bancaire et Financiére) and the National Bank of Belgium (Banque Nationale de Belgique); it holds securities for its participants and facilitates the clearance and settlement of securities transactions among them; it does so through simultaneous electronic book-entry delivery against payments, thereby eliminating the need for physical movement of certificates; it provides other services to its participants, including credit, custody, lending and borrowing of securities and tri-party collateral management; it interfaces with the domestic markets of several countries; its customers include banks, including central banks, securities brokers and dealers, banks, trust companies and clearing corporations and certain other professional financial intermediaries; indirect access to the Euroclear system is also available to others that clear through Euroclear customers or that have custodial relationships with Euroclear customers; and all securities in Euroclear are held on a fungible basis, which means that specific certificates are not matched to specific securities clearance accounts.

 

Clearance and Settlement Procedures

 

We understand that investors that hold their debt securities through Clearstream, Luxembourg or Euroclear accounts will follow the settlement procedures that are applicable to securities in registered form. Debt securities will be credited to the securities custody accounts of Clearstream, Luxembourg and Euroclear participants on the business day following the settlement date for value on the settlement date. They will be credited either free of payment or against payment for value on the settlement date.

We understand that secondary market trading between Clearstream, Luxembourg and/or Euroclear participants will occur in the ordinary way following the applicable rules and operating procedures of Clearstream, Luxembourg and Euroclear. Secondary market trading will be settled using procedures applicable to securities in registered form.

 

You should be aware that investors will only he able to make and receive deliveries, payments and other communications involving the debt securities through Clearstream, Luxembourg and Euroclear on business days. Those systems may not be open for business on days when banks, brokers and other institutions are open for business in the United States or Brazil.

 

In addition, because of time-zone differences, there may be problems with completing transactions involving Clearstream, Luxembourg and Euroclear on the same business day as in the United States or Brazil. U.S. and Brazilian investors who wish to transfer their interests in the debt securities, or to make or receive a payment or delivery of the debt securities on a particular day may find that the transactions will not be performed until the next business day in Luxembourg or Brussels, depending on whether Clearstream, Luxembourg or Euroclear is used.

 

Clearstream, Luxembourg or Euroclear will credit payments to the cash accounts of participants in Clearstream, Luxembourg or Euroclear in accordance with the relevant systemic rules and procedures, to the extent received by its depositary. Clearstream, Luxembourg or the Euroclear, as the case may be, will take any other action permitted to be taken by a holder under the indenture on behalf of a Clearstream, Luxembourg or Euroclear participant only in accordance with its relevant rules and procedures.

 

Clearstream, Luxembourg and Euroclear have agreed to the foregoing procedures in order to facilitate transfers of the debt securities among participants of Clearstream, Luxembourg and Euroclear. However, they are under no obligation to perform or continue to perform those procedures, and they may discontinue those procedures at any time.

 

Same-day settlement and payment

 

The underwriters will settle the debt securities in immediately available funds. We will make all payments of principal and interest on the debt securities in immediately available funds. Secondary market trading between participants in Clearstream, Luxembourg and Euroclear will occur in accordance with the applicable rules and operating procedures of Clearstream, Luxembourg and Euroclear and will be settled using the procedures applicable to securities in immediately available funds. See “ — Clearstream, Luxembourg and Euroclear” above.

 

Certificated debt securities

 

We will issue debt securities to you in certificated registered form only if:

 

 

If any of these three events occurs, the trustee will reissue the debt securities in fully certificated registered form and will recognize the registered holders of the certificated debt securities as holders under the indenture.

 

In the event that we issue certificated securities under the limited circumstances described above, then holders of certificated securities may transfer their debt securities in whole or in part upon the surrender of the certificate to be transferred, together with a completed and executed assignment form endorsed on the definitive debt security, at the offices of the transfer agent in New York City. Copies of this assignment form may be obtained at the offices of the transfer agent in New York City. Each time that we transfer or exchange a new debt security in certificated form for another debt security in certificated form, and after the transfer agent receives a completed assignment form, we will make available for delivery the new definitive debt security at the offices of the transfer agent in New York City. Alternatively, at the option of the person requesting the transfer or exchange, we will mail, at that person’s risk, the

new definitive debt security to the address of that person that is specified in the assignment form. In addition, if we issue debt securities in certificated form, then we will make payments of principal of, interest on and any other amounts payable under the debt securities to holders in whose names the debt securities in certificated form are registered at the close of business on the record date for these payments. If the debt securities are issued in certificated form, we will make payments of principal and any redemption payments against the surrender of these certificated debt securities at the offices of the paying agent in New York City.

 

Unless and until we issue the debt securities in fully-certificated, registered form,

 

 

PLAN OF DISTRIBUTION

 

At the time of offering any securities, we will supplement the following summary of the plan of distribution with a description of the offering, including the particular terms and conditions thereof, set forth in a prospectus supplement relating to those securities.

 

Each prospectus supplement with respect to a series of securities will set forth the terms of the offering of those securities, including the name or names of any underwriters or agents, the price of such securities and the net proceeds to us from such sale, any underwriting discounts, commissions or other items constituting underwriters’ or agents’ compensation, any discount or concessions allowed or reallowed or paid to dealers and any securities exchanges on which those securities may be listed.

 

We may sell the securities from time to time in their initial offering as follows:

 

 

In addition, we may issue the securities as a dividend or distribution or in a subscription rights offering to our existing security holders. In some cases, we or dealers acting with us or on our behalf may also purchase securities and reoffer them to the public by one or more of the methods described above. This prospectus may be used in connection with any offering of our securities through any of these methods or other methods described in the applicable prospectus supplement.

 

The securities we distribute by any of these methods may be sold to the public, in one or more transactions, either:

 

 

We may solicit offers to purchase securities directly from the public from time to time. We may also designate agents from time to time to solicit offers to purchase securities from the public on our behalf. The prospectus supplement relating to any particular offering of securities will name any agents designated to solicit offers, and will include information about any commissions we may pay the agents, in that offering. Agents may be deemed to be “underwriters” as that term is defined in the Securities Act of 1933.

 

From time to time, we may sell securities to one or more dealers acting as principals. The dealers, who may be deemed to be “underwriters” as that term is defined in the Securities Act of 1933, may then resell those securities to the public.

 

We may sell securities from time to time to one or more underwriters, who would purchase the securities as principal for resale to the public, either on a firm-commitment or best-efforts basis. If we sell securities to underwriters, we may execute an underwriting agreement with them at the time of sale and will name them in the applicable prospectus supplement. In connection with those sales, underwriters may be deemed to have received compensation from us in the form of underwriting discounts or commissions and may also receive commissions from purchasers of the securities for whom they may act as agents. Underwriters may resell the securities to or through dealers, and those dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from purchasers for whom they may act as agents. The applicable prospectus supplement will include any required information about underwriting compensation we pay to underwriters, and any discounts, concessions or commissions underwriters allow to participating dealers, in connection with an offering of securities.

If we offer securities in a subscription rights offering to our existing security holders, we may enter into a standby underwriting agreement with dealers, acting as standby underwriters. We may pay the standby underwriters a commitment fee for the securities they commit to purchase on a standby basis. If we do not enter into a standby underwriting arrangement, we may retain a dealer-manager to manage a subscription rights offering for us.

 

We may authorize underwriters, dealers and agents to solicit from third parties offers to purchase securities under contracts providing for payment and delivery on future dates. The applicable prospectus supplement will describe the material terms of these contracts, including any conditions to the purchasers’ obligations, and will include any required information about commissions we may pay for soliciting these contracts.

 

Underwriters, dealers, agents and other persons may be entitled, under agreements that they may enter into with us, to indemnification by us against certain liabilities, including liabilities under the Securities Act of 1933.

 

Each series of securities will be a new issue, and there will be no established trading market for any security prior to its original issue date. We may not list any particular series of securities on a securities exchange or quotation system. No assurance can be given as to the liquidity or trading market for any of the securities.

 

EXPENSES OF THE ISSUE

 

The following is a statement of expenses, other than underwriting discounts and commissions, in connection with the distribution of the securities registered. All amounts shown are estimates.

 

 

EXPERTS

 

The consolidated financial statements of Petrobras and PIFCo, appearing in the combined Petrobras and PIFCo Annual Report on Form 20-F for the year ended December 31, 2005, have been audited by Ernst & Young Auditores Independentes S/S, independent registered public accounting firm as set forth in their reports thereon included therein and incorporated herein by reference. Such consolidated financial statements are incorporated herein by reference in reliance upon such reports given on the authority of such firm as experts in accounting and auditing.

 

The unaudited consolidated financial information of Petrobras and PIFCo as of and for the nine-month periods ended September 30, 2006 and 2005, incorporated by reference in this Registration Statement on Form F-3, were reviewed by KPMG Auditores Independentes and Ernst & Young Auditores Independentes S/S, respectively. KPMG Auditores Independentes and Ernst & Young Auditores Independentes S/S have reported that they have applied limited procedures in accordance with professional standards for a review of such information. However, their separate reports included in the Petrobras Report on Form 6-K and the PIFCo Report on Form 6-K containing financial information for the nine-month periods ended September 30, 2006 and 2005, and incorporated herein by reference, state that they did not audit and they do not express an opinion on that unaudited interim financial information. Accordingly, the degree of reliance on such information should be restricted considering the limited nature of the review procedures applied. The independent accountants are not subject to the liability provisions of Section 11 of the Securities Act of 1933 for their report on the unaudited interim financial information because that report is not a “report” or a “part” of the registration statement prepared or certified by the auditors within the meaning of Sections 7 and 11 of the Act.

 

The summary reports of DeGolyer and MacNaughton, independent petroleum engineering consultants, which are referenced in this prospectus, have been referenced in this prospectus in reliance upon the authority of the firm as experts in estimating proved oil and gas reserves.

 

VALIDITY OF SECURITIES

 

Mr. Nilton de Almeida Maia, Petrobras’ general counsel, will pass upon the validity of the debt securities, warrants, preferred shares, common shares, mandatory convertible securities, guarantees and standby purchase agreements for Petrobras as to certain matters of Brazilian law. Walkers, special Cayman Islands counsel to PIFCo, will pass upon the validity of the debt securities issued by PIFCo as to certain matters of Cayman Islands law. The validity of the debt securities and debt warrants will be passed upon by Cleary Gottlieb Steen & Hamilton LLP or any other law firm named in the applicable prospectus supplement as to certain matters of New York law.

 

ENFORCEABILITY OF CIVIL LIABILITIES

 

Petrobras

 

Petrobras is a sociedade de economia mista (mixed-capital company), a public sector company with some private sector ownership, established under the laws of Brazil. All of its executive officers and directors and certain advisors named herein reside in Brazil. In addition, substantially all of its assets and those of its executive officers, directors and certain advisors named herein are located in Brazil. As a result, it may not be possible for investors to effect service of process upon Petrobras or its executive officers, directors and advisors named herein within the United States or other jurisdictions outside Brazil or to enforce against Petrobras or its executive officers, directors and advisers named herein judgments obtained in the United States or other jurisdictions outside Brazil.

 

Mr. Nilton de Almeida Maia, Petrobras’ general counsel, has advised Petrobras that, subject to the requirements described below, judgments of United States courts for civil liabilities based upon the United States federal securities laws may be enforced in Brazil. A judgment against Petrobras or the other persons described above obtained outside Brazil would be enforceable in Brazil, without reconsideration of the merits, only if the judgment satisfies certain requirements and receives confirmation from the Brazilian Superior Court of Justice (Superior Tribunal de Justiça). The foreign judgment will only be confirmed if:

 

 

Notwithstanding the foregoing, no assurance can be given that such confirmation would be obtained, that the process described above could be conducted in a timely manner or that a Brazilian court would enforce a monetary judgment for violation of the U.S. securities laws with respect to any securities issued by Petrobras.

 

Mr. Nilton de Almeida Maia has also advised Petrobras that:

 

 

 

PIFCo

 

PIFCo is duly incorporated as a tax exempt limited liability company under the laws of the Cayman Islands. All of the directors and officers of PIFCo reside in Brazil. All or a substantial portion of the assets of PIFCo and of such directors and officers are located outside of the United States. As a result, it may be difficult for investors to effect service of process within the United States upon PIFCo or such persons or to enforce, in the United States courts, judgment against PIFCo or such persons or judgments obtained in such courts predicated upon the civil liability provisions of the federal securities laws of the United States.

 

PIFCo has been advised by its Cayman Island counsel, Walkers, that although there is no statutory enforcement in the Cayman Islands of judgments obtained in New York, the courts of the Cayman Islands will, based on the principle that a judgment by a competent foreign court imposes upon the judgment debtor an obligation to pay the sum for which judgment has been given, recognize and enforce a foreign judgment of a court having jurisdiction over the defendant according to Cayman Islands conflict of law rules, if such judgment is final, for a liquidated sum not in respect of taxes or a fine or penalty, is not inconsistent with a Cayman Islands judgment in respect of the same matters and was not obtained in a manner, and is not a kind the enforcement of which is, contrary to natural justice, statute or the public policy of the Cayman Islands. There is doubt, however, as to whether the courts of the Cayman Islands will (i) recognize or enforce judgments of United states courts predicated upon the civil liability provisions of the securities laws of the United States or any state thereof, or (ii) in original actions brought in the Cayman Islands, impose liabilities upon the civil liability provisions of the securities laws of the United states or any state thereof, on the grounds that such provisions are penal in nature.

 

A Cayman Islands court may stay proceedings if concurrent proceedings are being brought elsewhere.
