SUMMARY

This summary highlights key information described in greater detail elsewhere, or incorporated by reference, in this prospectus supplement and the accompanying prospectus. This summary is not complete and does not contain all of the information you should consider before investing in the Notes. You should read carefully the entire prospectus supplement, the accompanying prospectus, including “Risk Factors” and the documents incorporated by reference herein, which are described under “Incorporation of Certain Documents by Reference” and “Where You Can Find More Information.”

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 “PGF” mean Petrobras Global Finance B.V., a wholly-owned subsidiary of Petrobras. Terms such as “we”, “us” and “our” generally refer to both Petrobras and PGF, unless the context requires otherwise or as otherwise indicated.

PGF

PGF is a wholly-owned finance subsidiary of Petrobras, incorporated under the laws of The Netherlands as a private company with limited liability on August 2, 2012. PGF is an indirect subsidiary of Petrobras, and all of PGF’s shares are held by Petrobras’s Dutch subsidiary Petrobras International Braspetro B.V. PGF’s business is to issue debt securities in the international capital markets to finance Petrobras’s operations. PGF does not currently have any operations, revenues or assets other than those related to the issuance, administration and repayment of its debt securities. All debt securities issued by PGF are fully and unconditionally guaranteed by Petrobras. PGF was incorporated for an indefinite period of time.

Petrobras uses PGF as its main vehicle to issue securities in the international capital markets.  PGF’s first offering of notes fully and unconditionally guaranteed by Petrobras occurred in September 2012.  In December 2014, PGF assumed the obligations of Petrobras’s former finance subsidiary Petrobras International Finance Company S.A. (“PifCo”) under all then outstanding notes originally issued by PifCo, which continue to benefit from Petrobras’s full and unconditional guarantee.

PGF’s registered office is located at Weenapoint Toren A, Weena 722, 3014 DA Rotterdam, The Netherlands, and its telephone number is 31 (0) 10 206-7000.

Petrobras

Petrobras is one of the world’s largest integrated oil and gas companies, engaging in a broad range of oil and gas activities. Petrobras is a sociedade de economia mista, organized and existing under the laws of Brazil. For the years ended December 31, 2013 and 2014, Petrobras had sales revenues of U.S.$141.5 billion and U.S.$143.7 billion, gross profit of U.S.$32.6 billion and U.S.$34.2 billion and net (loss) income attributable to Petrobras’s shareholders of U.S.$11.1 billion and U.S.$(7.4) billion, respectively. Petrobras engages in a broad range of activities, which cover the following segments of its operations:

·        Exploration and Production (E&P). This segment encompasses exploration, development and production activities in Brazil, sales and transfers of crude oil in domestic and foreign markets, transfers of natural gas to the Gas and Power segment and sales of oil products produced at natural gas processing plants. In 2014, our average domestic daily oil production was 2,034 thousand barrels per day, which represents more than 90% of Brazil’s total oil production.

·        Refining, Transportation and Marketing (RTM). This segment comprises refining, logistics, transportation, export and the purchase of crude oil, as well as the purchase and sale of oil products and ethanol. Additionally, this segment includes the petrochemical division, which comprises investments in domestic petrochemical companies and also extraction and processing of shale.  RTM purchases crude oil from E&P and imports oil to blend with Petrobras’ domestic oil. Additionally, RTM purchases oil products in the international markets to meet excess product demand in the domestic market. As of December 31, 2014, according to the ANP, we operated substantially all of Brazil’s total refining capacity.

·        Distribution. This segment comprises the oil products, ethanol and compressed natural gas distribution activities conducted in Brazil by Petrobras’ wholly-owned subsidiary Petrobras Distribuidora S.A. — BR (“Petrobras Distribuidora”). Petrobras Distribuidora is the largest oil products distributor in Brazil, with a market share of 37.9% as of December 31, 2014, according to the ANP. As of December 31, 2014, Petrobras Distribuidora had 7,931 service stations in Brazil.

·        Gas and Power. This segment covers activities that include transportation and trading of natural gas produced in or imported into Brazil, transportation and trading of liquefied natural gas (LNG), generation and trading of electric power, as well as corporate interests in local natural gas distribution companies, natural gas transportation companies and thermoelectric power stations in Brazil. The Gas and Power segment also includes results from our fertilizer operations.

·        Biofuel. This segment covers activities that include production of biodiesel and its co-products and ethanol activities, through equity investments, production and marketing of ethanol, sugar and the excess electric power generated from sugarcane bagasse.

·        International. This segment covers the activities of exploration and production of oil and gas, refining, transportation and marketing, gas and power, and distribution, carried out outside of Brazil in a number of countries in the Americas, Africa, Europe and Asia.

·        Corporate. This segment comprises financing activities and other activities not attributable to other segments, including corporate financial management, corporate overhead and other expenses, including expenses related to Petrobras’ pension and medical benefits for inactive participants and their dependents.

Petrobras’s principal executive office is located at Avenida República do Chile, 65, 20031-912 - Rio de Janeiro RJ, Brazil, and its telephone number is (55-21) 3224-4477.

The Offering

RISK FACTORS

Our annual report on Form 20-F for the year ended December 31, 2014 includes extensive risk factors relating to our operations, our compliance and control risks (including those related to material weaknesses in our internal control over financial reporting, the ongoing Lava Jato investigation and uncertainty relating to our methodology to estimate the incorrectly capitalized overpayments uncovered in the context of the Lava Jato investigation), our relationship with the Brazilian federal government, 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 in this prospectus supplement and the accompanying prospectus, before making a decision to invest in the Notes.

Risks Relating to PGF’s Debt Securities

The market for the Notes may not be liquid.

The Notes are an issuance of new securities with no established trading market. We intend to apply to list the Notes on the NYSE. 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 of the Notes will be able to sell their Notes in the future. If a market for the Notes does not develop, holders of the Notes 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’s ability to make payments to PGF in U.S. dollars.

In the past, the Brazilian economy has experienced balance of payment deficits and shortages in foreign exchange reserves, and the government has responded by restricting the ability of Brazilian or foreign persons or entities to convert reais into foreign currencies. The government may institute a restrictive exchange control policy in the future. Any restrictive exchange control policy could prevent or restrict our access to U.S. dollars, and consequently our ability to meet our U.S. dollar obligations under the guaranty and could also have a material adverse effect on our business, financial condition and results of operations. We cannot predict the impact of any such measures on the Brazilian economy.  In the event that any such restrictive exchange control policies were instituted by the Brazilian government, we may face adverse regulatory consequences in The Netherlands that may lead us to redeem the Notes prior to their maturity.

In addition, payments by Petrobras under the guaranty in connection with PGF’s Notes do not currently require approval by or registration with the Central Bank of Brazil. The Central Bank of Brazil may nonetheless impose prior approval requirements on the remittance of U.S. dollars, which could cause delays in such payments.

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’s obligations in respect of the guaranty, including in case of bankruptcy, 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. Further authorization by the Central Bank of Brazil would be required for the conversion of such real-denominated amount into foreign currency and for its remittance abroad.

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

PGF’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 a guaranty, and Petrobras, at the time it issued the guaranty:

·        was or is insolvent or rendered insolvent by reason of its entry into such 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’s obligations under such guaranty could be avoided, or claims with respect to such 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 PGF’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 PGF Notes supported by such guaranty would not have a claim against Petrobras under such guaranty and will solely have a claim against PGF. Petrobras cannot assure you that, after providing for all prior claims, there will be sufficient assets to satisfy the claims of the PGF holders relating to any avoided portion of the guaranty.

Holders in some jurisdictions may not receive payment of gross-up amounts for withholding in compliance with the European Council Directive on taxation of savings income.

Austria and Luxembourg have opted out of certain provisions of the European Council Directive regarding taxation of savings income (the “Directive”) and are instead, during a transitional period, applying a withholding tax on payments of interest, at a rate of up to 35%, unless the holder opts for exchange of information as required under the Directive.  Neither we nor the paying agent (nor any other person) would be required to pay additional amounts in respect of the Notes as a result of the imposition of withholding tax by any member state of the European Union (“Member State”) or another country or territory which has opted for a withholding system. For more information, see “Description of the Notes—Covenants—Additional Amounts” and under “Taxation—The Directive” in this prospectus supplement.  An investor should consult a tax adviser to determine the tax consequences of holding the Notes for such investor.

A downgrade in our credit rating could negatively impact our cost of and ability to access capital.

On February 24, 2015, Moody’s Investors Service downgraded all of our credit ratings to below investment grade, and it confirmed those ratings with a stable outlook on April 27, 2015.  Our ability to access capital markets or to otherwise obtain sufficient financing is enhanced by our credit ratings as provided by the major U.S. credit rating agencies and our historical ability to access those markets as needed. Factors that may impact our credit ratings include debt levels, planned asset purchases or sales and near-term and long-term production growth opportunities.  Liquidity, asset quality, cost structure, product mix and commodity pricing levels, among other things, are also considered by the rating agencies.  A ratings downgrade could adversely impact our ability to access debt markets in the future, increase the cost of future debt and potentially require us to post letters of credit for certain obligations.

Risks Relating to PGF and Petrobras

PGF’s operations and debt servicing capabilities are dependent on Petrobras.

PGF’s financial position and results of operations are directly affected by Petrobras’s decisions. PGF is an indirect, wholly-owned finance subsidiary of Petrobras incorporated in The Netherlands as a private company with limited liability.  PGF does not currently have any operations, revenues or assets other than those related to its primary business of raising money for the purpose of on-lending to Petrobras and other subsidiaries of Petrobras.  PGF’s ability to satisfy its obligations under the Notes will depend on payments made to PGF by Petrobras and other subsidiaries of Petrobras under the loans made by PGF.  The Notes and all debt securities issued by PGF will be fully and unconditionally guaranteed by Petrobras.  Petrobras’s financial condition and results of operations, as well as Petrobras’s financial support of PGF, directly affect PGF’s operational results and debt servicing capabilities.

We may face additional civil proceedings related to the Lava Jato investigation.

We are subject to a number of civil proceedings related to the Lava Jato investigation, including five putative securities class action complaints that were filed against us in the United States District Court for the Southern District of New York (“SDNY”) and consolidated on February 17, 2015. See Item 8. “Financial Information—Legal Proceedings” of our 2014 Form 20-F and Note 30.2 to our audited consolidated financial statements contained therein. Since February 17, 2015, nine additional individual actions have been filed by investors in the SDNY consisting of allegations similar to those in the consolidated amended complaint. The plaintiffs have not specified an amount of alleged damages in the actions. Because these actions are in their early stages, the possible loss or range of losses, if any, arising from the litigation cannot be estimated. Petrobras has engaged a U.S. firm as legal counsel and intends to defend vigorously against the allegations made in the context of these actions. It is possible that additional complaints or claims might be filed in the United States, Brazil or elsewhere against us relating to the Lava Jato investigation in the future. Our management may be required to direct its time and attention to defending these claims, which could prevent them from focusing on our core business. Depending on the outcome, such litigation could also result in restrictions on our operations and have a material adverse effect on our business. For more information, see Item 3. “Key Information—Risk Factors—We may incur losses and spend time and financial resources defending pending litigations and arbitrations” of our 2014 Form 20-F.

Our commitment to meet the obligations of our pension plan (“Petros”) and health care benefits may be higher than what is currently anticipated, and we may be required to make additional contributions of resources to Petros.

The criteria used for determining commitments relating to pension and health care plan benefits are based on actuarial and financial estimates and assumptions with respect to (i) the calculation of projected short-term and long-term cash flows and (ii) the application of internal and external regulatory rules. Therefore, there are uncertainties inherent in the use of estimates that may result in differences between the predicted value and the actual value realized.

In addition, the assets held by Petros to cover pension obligations are subject to risks inherent to investment management and such assets may not generate the necessary returns to cover the relevant liabilities. Further, Petros may be required to assume the payment of additional obligations arising from court decisions unfavorable to the plan. With respect to the results of Petros, under current Brazilian law, in the event of deficits in specific circumstances, an equalization plan may be necessary and, therefore, extraordinary contributions from us, as sponsors, may be required.

With respect to health care, the projected cash flows, as well as payments and actuarial liabilities, may also be impacted by (i) substantial increases in medical costs, (ii) additional demands for better benefits and (iii) the difficulty of adjusting the contributions of participants proportionally to cost increases.

These risks may result in an increase in our liabilities and adversely affect our results of operations and our business.

USE OF PROCEEDS

The net proceeds from the sale of the Notes, after payment of underwriting discounts but before expenses, are expected to be approximately U.S.$         million.  PGF intends to use the net proceeds from the sale of the Notes for general corporate purposes.

·        The maturity of any indebtedness of PGF or Petrobras or a material subsidiary in a total aggregate principal amount of U.S.$200,000,000 (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 a material subsidiary of any indebtedness is not acceleration for this purpose.

·        PGF or Petrobras or any material subsidiary stops paying or is generally unable to pay its debts as they become due, except in the case of a winding-up, dissolution or liquidation for the purpose of and followed by a consolidation, spin-off, merger, conveyance or transfer duly approved by the note holders.

·        In the case PGF or Petrobras or any material subsidiary, if proceedings are initiated against it under any applicable liquidation, insolvency, composition, reorganization, winding up or any other similar laws, or under any other law for the relief of, or relating to, debtors, and such proceeding is not dismissed or stayed within 90 calendar days.

·        An administrative or other receiver, manager or administrator, or any such or other similar official is appointed in relation to, or a distress, execution, attachment, sequestration or other process is levied or put in force against, the whole or a substantial part of the undertakings or assets of PGF or Petrobras or any material subsidiary and is not discharged or removed within 90 calendar days.

·        PGF or Petrobras or any material subsidiary voluntarily commences proceedings under any applicable liquidation, insolvency, composition, reorganization or any other similar laws, PGF or Petrobras or any material subsidiary enters into any composition or other similar arrangement with our creditors under applicable Brazilian law (such as a recuperação judicial or extrajudicial, which is a type of liquidation agreement).

·        An effective resolution is passed, or any authorized action is taken by any court of competent jurisdiction, directing PGF or Petrobras or any material subsidiary’s winding-up, dissolution or liquidation, except for the purpose of and followed by a consolidation, merger, conveyance or transfer duly approved by the note holders.

·        The Notes, the indenture, the guaranty or any part of those documents cease to be in full force and effect or binding and enforceable against PGF or Petrobras, or it becomes unlawful for PGF or Petrobras to perform any material obligation under any of the foregoing documents to which it is a party.

·        PGF 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 PGF.

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 IFRS, would be a capital lease obligation).

·        “material subsidiary” means a subsidiary of Petrobras which on any given date of determination accounts for more than 15% of Petrobras’s total consolidated assets (as set forth on Petrobras’s most recent balance sheet prepared in accordance with IFRS).

Covenants

PGF will be subject to the following covenants with respect to the Notes:

Payment of Principal and Interest

PGF 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 PGF) on the Notes in accordance with the Notes and the indenture.

Maintenance of Corporate Existence

PGF 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 PGF’s board of directors determines that maintaining such rights and privileges is no longer desirable in the conduct of PGF’s business and is not disadvantageous in any material respect to holders.

Maintenance of Office or Agency

So long as Notes are outstanding, PGF 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, 43^rd Floor, New York, New York 10022-6837. PGF 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

PGF 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

PGF intends to use the net proceeds from the sale of the Notes for general corporate purposes.

Statement by Managing Directors as to Default

PGF will deliver to the trustee, within 90 calendar days after the end of its fiscal year, a directors’ certificate, stating whether or not to the best knowledge of its signers thereof there is an event of default in connection with the performance and observance of any of the terms, provisions and conditions of the indenture or the Notes and, if there is such an event of default by PGF, specifying all such events of default and their nature and status of which the signers may have knowledge.

Provision of Financial Statements and Reports

In the event that PGF files any financial statements or reports with the SEC or publishes or otherwise makes such statements or reports publicly available in The Netherlands, the United States or elsewhere, PGF 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.  As long as the financial statements or reports are publicly available and accessible electronically by the trustee, the filing or electronic publication of such financial statements or reports will comply with PGF’s obligation to deliver such statements and reports to the trustee.  PGF will provide to the trustee with prompt written notification at such time that PGF becomes or ceases to be a reporting company.  The trustee will have no obligation to determine if and when PGF’s financial statements or reports, if any, are publicity available and accessible electronically.

Along with each such financial statement or report, if any, PGF will provide a directors’ certificate stating (i) that a review of PGF’s activities has been made during the period covered by such financial statements with a view to determining whether PGF has kept, observed, performed and fulfilled its covenants and agreements under this indenture; and (ii) that no 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.

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 PGF’s compliance with any of its covenants under the indenture (as to which the trustee is entitled to rely exclusively on directors’ certificates).

Appointment to Fill a Vacancy in Office of Trustee

PGF, 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

PGF 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, PGF or Petrobras, as applicable, 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 PGF’s incorporation (currently The Netherlands) or any jurisdiction in which PGF appoints a paying agent under the indenture, or any political subdivision of such jurisdictions (the “taxing jurisdictions”). If PGF or Petrobras, as applicable, is required by law to withhold or deduct any taxes, levies, deductions or other governmental charges, PGF or Petrobras, as applicable, 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. For the avoidance of doubt, the foregoing obligations shall extend to payments under the guaranty.

All references to principal, premium, if any, and interest in respect of the Notes will be deemed to refer to any additional amounts which may be payable as set forth in the indenture or in the Notes.

PGF or Petrobras, as applicable, 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 or receiving principal or interest payments on 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, PGF or Petrobras, as applicable, 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 PGF has made available to the holder a payment under the Notes and the indenture, provided that PGF or Petrobras, as applicable, 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;

·       such taxes, levies, deductions or other governmental charges are imposed on a payment on the Notes by PGF’s paying agent (that is located in another member state of the European Union) to an individual and are required to be made pursuant to the European Council Directive on taxation of savings income in the form of interest payments (2003/48/EC) (as amended by the European Council Directive 2006/98/EC of November 20, 2006), or any implementing law, or any law that has been introduced in order to conform to such Directive, and such holder has not opted to agree to an exchange of information within the meaning of 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 PGF 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.

PGF 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 a taxing jurisdiction 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. PGF shall indemnify and make whole the holders of the Notes for any present or future stamp, court or documentary taxes or any other excise or property taxes, charges or similar levies payable by PGF as provided in this paragraph paid by such holder. PGF shall 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.

Holders in some jurisdictions may not receive payment of gross-up amounts for withholding in compliance with the Directive. See “Risk Factors—Holders in some jurisdictions may not receive payment of gross-up amounts for withholding in compliance with the European Council Directive on taxation of savings income.”

Negative Pledge

So long as the Notes remain outstanding, PGF will not create or permit any lien, other than a PGF permitted lien, on any of its assets to secure (i) any of its indebtedness or (ii) the indebtedness of any other person, unless PGF contemporaneously creates or permits such lien to secure equally and ratably its obligations under the Notes as is duly approved by a resolution of the holders of the Notes in accordance with the indenture. In addition, PGF will not allow any of its material subsidiaries, if any, to create or permit any lien, other than a PGF 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 PGF provides such other security for such Notes and the indenture or PGF provides such other security for the Notes as is duly approved by a resolution of the holders of the Notes in accordance with the indenture. This covenant is subject to a number of important exceptions, including an exception that permits PGF 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 20% of PGF’s consolidated total assets (as determined in accordance with IFRS) at any time as at which PGF’s balance sheet is prepared and published in accordance with applicable law.

Limitation on Consolidation, Merger, Sale or Conveyance

PGF will not, in one or a series of transactions, consolidate or amalgamate with or merge into any corporation or convey, lease, spin-off 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 PGF) to merge with or into it unless such consolidation, amalgamation, merger, lease, spin-off or transfer of properties, assets or revenues does not violate any provision of Dutch financial regulatory laws and:

·        either PGF is the continuing entity or the person (the “successor company”) formed by the consolidation or into which PGF is merged or that acquired (through a transfer of assets, a spin-off or otherwise) or leased the property or assets of PGF will assume (jointly and severally with PGF unless PGF will have ceased to exist as a result of that merger, consolidation or amalgamation), by a supplemental indenture, all of PGF’s obligations under the indenture and the Notes;

·        the successor company (jointly and severally with PGF unless PGF 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, spin-off, 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;

·        PGF has delivered to the trustee a directors’ 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 August 29, 2012, and that all conditions precedent provided for in the indenture and relating to the transaction have been complied with; and

·        PGF 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:

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

·        any direct or indirect subsidiary of PGF may merge or consolidate with or into, or convey, transfer, spin-off, lease or otherwise dispose of assets to, any person (other than PGF or any of its subsidiaries or affiliates) in cases when the transaction would not have a material adverse effect on PGF and its subsidiaries taken as a whole; or

·        any direct or indirect subsidiary of PGF may merge or consolidate with or into, or convey, transfer, spin-off, lease or otherwise dispose of assets to, any other direct or indirect subsidiary of PGF or Petrobras; or

·        any direct or indirect subsidiary of PGF may liquidate or dissolve if PGF 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 PGF and its subsidiaries taken as a whole and if the liquidation or dissolution is part of a corporate reorganization of PGF or Petrobras.

PGF 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, PGF’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 which has been borrowed or raised (including money raised by acceptances and all leases which, under IFRS, would be a capital lease obligation).

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

(d)   lien granted upon or with respect to any assets hereafter acquired by PGF 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 PGF or another wholly-owned subsidiary;

(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 (c)), 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) 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 PGF permitted liens pursuant to another part of this definition of PGF permitted liens, does not exceed 20% of PGF’s consolidated total assets (as determined in accordance with IFRS) at any date as at which PGF’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

PGF 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 (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. 

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 business day prior to any 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.

Optional Redemption With “Make-Whole” Amount for the Notes

PGF will have the right at our option to redeem 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 with respect to the Notes (the “Make-Whole Amount”), plus 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 Independent Investment Banker obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations.

“Reference Treasury Dealer” means each of Deutsche Bank Securities Inc. and J.P. Morgan Securities LLC, and, 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 Independent Investment Banker, 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 Independent Investment Banker 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 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 such 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 PGF 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.

Deemed Actions by Holders of the Notes by Acceptance

Each holder of a Note, by acquiring an interest in a Note, will be deemed to have agreed to treat the Note as indebtedness for all applicable U.S. federal income tax purposes, except to the extent required by applicable law.

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 those 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 with respect to the Notes will be part of the same series as such Notes that PGF 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

PGF intends to apply to have the Notes approved for listing on the NYSE.

Currency Rate Indemnity

PGF 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”), PGF will indemnify the relevant holder and the trustee 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 PGF’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,  Paying Agent and Transfer Agent

The Bank of New York Mellon, a New York banking corporation, is the trustee under the indenture and has been appointed by PGF as registrar, paying agent and transfer agent with respect to the Notes. The address of the trustee is 101 Barclay Street, 7E, New York, New York, 10286. PGF 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 or any agent named above 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 or any agent shall be a party, or any corporation or association to which all or substantially all of the corporate trust business of the trustee or any agent may be sold or otherwise transferred, shall be the successor trustee or relevant agent, as applicable, hereunder without any further act.

CLEARANCE AND SETTLEMENT

Book-Entry Issuance

Except under the limited circumstances described in the accompanying prospectus, 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 “—The 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 in the accompanying prospectus, all references to “registered holders” of Notes shall mean DTC.  PGF, Petrobras, the trustee and any paying agent, transfer agent, registrar or other agent may treat DTC as the absolute owner of the Notes for all purposes.

Primary Distribution

Payment Procedures

Payment for the Notes will be made on a delivery versus payment basis.

Clearance and Settlement Procedures

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. Notes 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 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.

DESCRIPTION OF THE GUARANTY

General

In connection with the execution and delivery of the twentieth supplemental indenture and the Notes offered by this prospectus supplement, Petrobras will guarantee the Notes (the “guaranty”) 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 PGF’s obligations under the Notes or Petrobras’s obligations under the guaranty.

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.

In addition, Petrobras’s obligations under the guaranty of the Notes rank, and will rank, pari passu with its obligations in respect of outstanding and future guaranties of indebtedness issued by PGF.

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 PGF’s obligations now or hereafter existing under the indenture and the Notes, whether for principal, interest, make-whole premium, fees, indemnities, costs, expenses, tax payments 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 PGF 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 PGF 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 the 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 twentieth supplemental indenture, however, contains events of default relating to Petrobras that may trigger an event of default and acceleration of the Notes. See “Description of the Notes―Events of Default.” Upon any such acceleration (including any acceleration arising out of the insolvency or similar events relating to Petrobras), if PGF 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, as applicable, to comply with the terms of the following covenants:

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 the Notes are 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’s existing principal U.S. office at 570 Lexington Avenue, 43^rd 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.

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 IFRS, and (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 IFRS.  As long as the financial statements or reports are publicly available and accessible electronically by the trustee, the filing or electronic publication of such financial statements or reports will comply with the Petrobras’s obligation to deliver such statements and reports to the trustee.  The trustee will have no obligation to determine if and when Petrobras’s financial statements or reports, if any, are publicity available and accessible electronically.

Along with each such financial statement or report, if any, Petrobras will provide an officers’ certificate stating that a review of Petrobras’s and PGF’s activities has been made during the period covered by such financial statements with a view to determining whether Petrobras and PGF 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, of the Notes) 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.

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’s 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 guaranty as is duly approved by a resolution of the holders of the Notes 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’s 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’s 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 holders of the Notes in accordance with the indenture.

Petrobras will not, in one or a series of transactions, consolidate or amalgamate with or merge into any corporation or convey, lease, spin-off 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 (through a transfer of assets, a spin-off or otherwise) 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 guaranty, all of Petrobras’s obligations under the 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, spin-off, 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; and

·        Petrobras has delivered to the trustee an officers’ certificate and an opinion of counsel, each stating that that such merger, consolidation, sale, spin-off, transfer or other conveyance or disposition and the amendment to the guaranty comply with the terms of the guaranty and that all conditions precedent provided for in the guaranty and relating to such transaction have been complied with.

Notwithstanding anything to the contrary in the foregoing, so long as no default or event of default under the indenture or the Notes 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, spin-off, 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;

·        any direct or indirect subsidiary of Petrobras may merge or consolidate with or into, or convey, transfer, spin-off, lease or otherwise dispose of assets to, any person (other than Petrobras or any of its subsidiaries or affiliates) in cases when such transaction would not have a material adverse effect on Petrobras and its subsidiaries taken as a whole;

·        any direct or indirect subsidiary of Petrobras may merge or consolidate with or into, or convey, transfer, lease or otherwise dispose of assets to, any other direct or indirect subsidiary of Petrobras; or

·        any direct or indirect subsidiary of Petrobras may liquidate or dissolve if Petrobras determines in good faith that such liquidation or dissolution is in the best interests of Petrobras, and would not result in a material adverse effect on Petrobras and its subsidiaries taken as a whole and if such liquidation or dissolution is part of a corporate reorganization of Petrobras.

Amendments

The guaranty 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 Notes. 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 holders of the Notes. 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.

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’s New York office located at 570 Lexington Avenue, 43^rd Floor, New York, New York 10022-6837. The guaranty 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 guaranty (or any document delivered pursuant thereto) and to the extent that in any jurisdiction there may be immunity attributed to Petrobras, PGF 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 relevant holder and the trustee 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’s 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     , by and among PGF, Petrobras and Deutsche Bank Securities Inc. and J.P. Morgan Securities LLC, as underwriters, each underwriter has severally agreed to purchase, and PGF has agreed to sell to the underwriters, the number of Notes set forth opposite the name of such underwriters below:

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 Notes may be offered and sold through certain of the underwriters’ affiliates.

The underwriting agreement provides that PGF 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.

PGF 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. 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, PGF and their affiliates for which the underwriters have received or expect to receive customary fees.

In addition, in the ordinary course of their business activities, the underwriters and their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. If any of the underwriters or their affiliates has a lending relationship with us, certain of those underwriters or their affiliates routinely hedge, and certain other of those underwriters or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies.  Typically, these underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the Notes offered hereby.  Any such credit default swaps or short positions could adversely affect future trading prices of the Notes offered hereby. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

The underwriters and/or their affiliates may acquire the Notes for their own property accounts. Such acquisitions may have an effect on demand for and the price of the Notes.

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%.

The expenses of the offering, excluding the underwriting discount, are estimated to be U.S.$1.2 million and will be borne by PGF.

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 PGF except as set forth in the underwriting agreement.

Neither PGF 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 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 0.25% 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.

TAXATION

The following discussion summarizes certain U.S. federal income, Brazilian and Dutch tax considerations that may be relevant to the ownership and disposition of the Notes acquired in this offering at their original issue price.  This summary does not describe all of the tax considerations that may be relevant to you or your situation, particularly if you are subject to special tax rules. You should consult your tax advisors about the tax consequences of holding the Notes, including the relevance to your particular situation of the considerations discussed below, as well as of any other tax laws.  There currently are no income tax treaties between Brazil and the United States. Although Brazilian and U.S. tax authorities have had discussions that may culminate in such a treaty, we cannot make any assurances regarding whether or when such a treaty will enter into force or how it will affect holders of the Notes.

U.S. Federal Income Tax Considerations

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 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 or other financial institutions, tax-exempt entities, partnerships (or entities or arrangements treated as partnerships for U.S. federal income tax purposes) or partners therein, insurance companies, dealers in securities or currencies, traders in securities electing to mark to market, persons that will hold the 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.  In addition, the discussion does not address the alternative minimum tax, the U.S. federal estate and gift tax, the Medicare tax on net investment income or other aspects of U.S. federal income or state and local taxation that may be relevant to an investor.  A “Non-U.S. Holder” is a beneficial owner of the Notes (other than a partnership or other entity or arrangement treated as a partnership for U.S. federal income tax purposes) that is not a U.S. Holder.

This summary is based on the Internal Revenue Code of 1986, as amended, existing, proposed and temporary U.S. Treasury regulations and judicial and administrative interpretations thereof, in each case as of 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 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, the Medicare tax on net investment income, U.S. STATE AND LOCAL TAX LAWS AND FOREIGN TAX LAWS.

Characterization of the Notes

The characterization of a security as debt or equity for U.S. federal income tax purposes depends on all of the facts and circumstances and is not always entirely clear.  There is no statutory, judicial or administrative authority that directly addresses the U.S. federal income tax treatment of securities similar to the Notes. Although there is no authority directly on point and therefore the issue is not free from doubt, we expect that the Notes will be classified as indebtedness for U.S. federal income tax purposes.  Accordingly, we intend to take the position that the Notes are treated as indebtedness for U.S. federal income tax purposes and, by acquiring an interest in a Note, each beneficial owner of a Note agrees to treat the Notes as indebtedness for such purposes.  Except where clearly indicated otherwise, the remainder of this discussion assumes such treatment. 

No ruling has been or will be sought from the Internal Revenue Service (“IRS”) with respect to the classification of the Notes, and no assurance can be given that the IRS would not assert, or that a court would not sustain, a contrary determination.  If the Notes were classified in a manner other than as indebtedness, the U.S. federal income tax consequences could differ from the consequences described below. For example, if the Notes were to be treated as an equity interest in PGF and if PGF is considered to be a “passive foreign investment company” (a “PFIC”) as defined for U.S. federal income tax purposes, the Notes generally would be taxed in a manner similar to that described below, but adverse tax consequences may apply (i) with respect to any gain recognized upon a taxable disposition of a Note or (ii) for a U.S. Holder that fails to include certain PFIC-related information in its U.S. federal income tax return.  As described above, each beneficial owner of a Note agrees to treat the Notes as indebtedness for such purposes, except to the extent required by applicable law.  See “Description of the Notes—Deemed Actions by Holders of the Notes by Acceptance.” Nevertheless, a U.S. Holder classifying the Notes in a manner other than as indebtedness should provide notice of such classification on its U.S. federal income tax return.  You should consult your tax advisor as to the characterization of the Notes for U.S. federal income tax purposes and consequences to you of the purchase, ownership and disposition of the Notes.

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.

It is expected that the Notes will not be considered as issued with original issue discount (“OID”) in excess of a de minimis amount. In general, however, if the Notes are issued with OID that is more than a de minimis amount, regardless of a U.S. Holder’s regular method of accounting for U.S. federal income tax purposes, such holder will have to include OID as ordinary gross income under a “constant yield method” before the receipt of cash attributable to such income.

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 for most U.S. Holders. 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 the 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 so long as such income is not 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 to the extent not previously included in gross income) and such U.S. Holder’s tax basis in the Note. A U.S. Holder’s tax basis in the Note will generally equal such U.S. Holder’s purchase price of 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. 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 income tax liability unless such credit can be applied (subject to the 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 so long as (i) such gain is not 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 not present in the United States for 183 days or more in the taxable year of the disposition. Non-U.S. Holders should consult their own tax advisors in the event either of the foregoing conditions applies.

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 IRS.

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. This 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 NOTES, INCLUDING, WITHOUT LIMITATION, THE CONSEQUENCES OF THE RECEIPT OF INTEREST AND THE SALE OR OTHER DISPOSITION OF THE NOTES OR COUPONS.

Payments in Respect of the Notes, and Sale or Other Disposition of Notes

Generally, an individual, entity, trust or organization that is domiciled for tax purposes outside Brazil (a “Non-Resident”) is subject to income tax in Brazil only when income is derived from Brazilian source or when the transaction giving rise to such earnings involves assets located in Brazil. Therefore, based on the fact that PGF is considered to be domiciled abroad for tax purposes, any interest, gains, fees, commissions, expenses and any other income paid by PGF in respect of the Notes it issues to Non-Resident holders should not, under Brazilian law, be regarded as payable by a Brazilian obligor. Accordingly, no Brazilian income or withholding taxes should apply to payments made by the issuer, provided that such payments are made with funds held by PGF outside of Brazil.

Any capital gains generated outside Brazil as a result of a transaction between two Non-Resident holders with respect to assets not located in Brazil are generally not subject to tax in Brazil.  If the assets are located in Brazil, then capital gains realized thereon are subject to income tax, according to Law No. 10,833, enacted on December 29, 2003.  Since the Notes will be issued and registered abroad, the Notes should not fall within the definition of assets located in Brazil for purposes of Law No. 10,833. Therefore, gains realized on the sale or other disposition of the Notes made outside Brazil by a Non-Resident holder to another non-Brazilian resident should not be subject to Brazilian taxes. Notwithstanding the foregoing, considering the general and unclear scope of this legislation and the absence of judicial guidance in respect thereof, we cannot assure prospective investors that such interpretation will prevail in the courts of Brazil.

As a result, gains realized by a Non-Resident holder from the sale or other disposition of the Notes (i) to a Non-Resident in case the Notes are deemed to be located in Brazil or (ii) to a resident of Brazil may be subject to income tax in Brazil at a rate of 15%.  A 25% rate, however, may apply if such Non-Resident holder is located in a country (i) that does not impose any income tax, (ii) that imposes income tax at a maximum rate lower than 17% (a “Low or Nil Tax Jurisdiction”) or (iii) where the local laws do not allow access to information related to the shareholding composition of legal entities, to their ownership or to the identity of the effective beneficiary of the income attributed to non-residents.  A lower rate, however, may apply under an applicable tax treaty between Brazil and the country where the Non-Resident holder has its domicile.

Payments Made by Petrobras as Guarantor

Interest, fees, commissions, expenses and any other income payable by Petrobras as guarantor resident in Brazil to a Non-Resident holder are generally subject to income tax withheld at source. The rate of withholding in respect of interest payments is generally 15%, unless (i) the holder of the Notes is resident or domiciled in a Low or Nil Tax Jurisdiction, in which case the applicable rate is 25%, or (ii) such other lower rate as provided for in an applicable tax treaty between Brazil and the country where the beneficiary is domiciled. In case the guarantor is required to assume the obligation to pay the principal amount of the Notes, Brazilian tax authorities could attempt to impose withholding income tax as described above.

If the payments with respect to the Notes are made by Petrobras as a guarantor, then Non-Resident holders will be indemnified so that, after payment of applicable Brazilian taxes imposed by deduction or withholding with respect to principal or interest payable with respect to the Notes, subject to certain exceptions, as mentioned in “Description of the Notes—Covenants—Additional Amounts”, a Non-Resident holder will receive an amount equal to the amount that such Non-Resident holder would have received if no such taxes were imposed. See “Description of the Notes—Covenants—Additional Amounts.”

Low or Nil Tax Jurisdictions and Privileged Tax Regimes

On June 4, 2010, Brazilian tax authorities adopted Normative Instruction No. 1,037 listing (i) the countries and jurisdictions considered as Low or Nil Tax Jurisdictions and (ii) the “privileged tax regimes,” which definition is provided by Law No. 11,727, of June 23, 2008.  Although we believe that the best interpretation of the current tax legislation could lead to the conclusion that the “privileged tax regime” concept should solely apply for purposes of Brazilian transfer pricing and thin capitalization rules, we cannot assure whether subsequent legislation or interpretations by the Brazilian tax authorities will not also make it applicable to a Non-Resident holder with respect to payments potentially made by a Brazilian source.

We recommend prospective investors consult their own tax advisors regarding the tax consequences arising from Normative Instruction No. 1,037 and Law No. 11,727.  If the Brazilian tax authorities determine that payments made to a Non-Resident holder are within the scope of a “privileged tax regime,” then the withholding income tax applicable to such payments could be up to 25%.

Other Tax Considerations

Brazilian law imposes a tax on foreign exchange transactions (Imposto sobre Operações de Crédito, Câmbio, Seguros e sobre Operações relativas à Títulos e Valores Mobiliários) (the “IOF/Exchange”) on the conversion of reais into foreign currency and on the conversion of foreign currency into reais, including foreign exchange transactions in connection with payments made by a Brazilian guarantor under the guaranty to Non-Resident holders.

Currently, the IOF/Exchange rate is 0.38% for most foreign exchange transactions, including foreign exchange transactions in connection with payments by Petrobras to Non-Resident holders under the guaranty. However, the IOF/Exchange rate can be increased by the Brazilian Government at any time up to a maximum rate of 25%. Any such new rate would only apply to future foreign exchange transactions.

Generally, there are no inheritance, gift, succession, stamp, or other similar taxes in Brazil with respect to the ownership, transfer, assignment or 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.

Dutch Tax Considerations

The following describes certain Dutch tax consequences for a holder who is neither a resident nor deemed to be a resident of The Netherlands for Dutch tax purposes in respect of the ownership, acquisition and disposal of the Notes.

For the purpose of this section, “Dutch Taxes” shall mean taxes of whatever nature levied by or on behalf of The Netherlands or any of its subdivisions or taxing authorities. The Netherlands means the part of the Kingdom of the Netherlands located in Europe.

This section is intended as general information only, does not constitute tax or legal advice and it does not purport to describe all possible Dutch tax considerations or consequences that may be relevant to a holder and therefore should be treated with appropriate caution.  This overview is based on the laws of The Netherlands currently in force and as applied on the date of this prospectus, which are subject to change, possibly also with retroactive or retrospective effect.

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

For Dutch tax purposes, a holder of Notes may include, without limitation:

·        an owner of one or more Notes who, in addition to the title to such Notes, has an economic interest in such Notes,

·        a person or an entity that holds the entire economic interest in one or more Notes,

·        a person or an entity that holds an interest in an entity, such as a partnership or a mutual fund, that is transparent for Dutch tax purposes, the assets of which comprise one or more Notes, and

·        a person who is deemed to hold an interest in Notes, as referred to under any of the above,      pursuant to the attribution rules of article 2.14a, of the Dutch Income Tax Act 2001, with respect to property that has been segregated, for example, in a trust or a foundation.

This section does not describe all the possible Dutch tax consequences that may be relevant to the holder of the Notes who receives or has received any benefits from these Notes as employment income, deemed employment income or otherwise as compensation.

Dutch Individual and Corporate Income Tax

A holder of Notes will not be treated as a resident of The Netherlands by reason only of the holding of a Note or the execution, performance, delivery and/or enforcement of the Notes.

A holder who is not a resident of The Netherlands, nor deemed to be a resident, is not taxable on income derived from the Notes and capital gains realized upon the disposal or redemption of the Notes, except if:

(i)               such the holder derives profits from an enterprise, whether as entrepreneur (ondernemer) or pursuant to a co-entitlement to the net worth of the enterprise, other than as an entrepreneur or a shareholder, which enterprise is, in whole or in part, carried on through a permanent establishment (vaste inrichting) or a permanent representative (vaste vertegenwoordiger) in The Netherlands, to which the Notes are attributable;

(ii)              the holder is an individual and derives benefits from miscellaneous activities (overage werkzaamheden) carried out in The Netherlands in respect of the Notes, including without limitation activities which are beyond the scope of active portfolio investment activities; or

(iii)             the holder is not an individual and is entitled to a share in the profits of an enterprise or a co-entitlement to the net worth of an enterprise, which is effectively managed in The Netherlands, other than by way of securities, and to which enterprise the Notes are attributable;

(iv)             if the holder is an individual and is entitled to a share in the profits of an enterprise that is effectively managed in The Netherlands, other than by way of securities, and to which enterprise the Notes are attributable.

Dutch Withholding Tax

All payments of interest and principal by PGF under the Notes can be made free of withholding or deduction for any taxes of any nature imposed, levied, withheld or assessed by The Netherlands or any political subdivision or taxing authority thereof or therein, except where Notes (i) are issued under such terms and conditions that such Notes are capable of being classified as equity of PGF for Dutch tax purposes or (ii) actually function as equity of the PGF within the meaning of article 10, paragraph 1, letter d, of the Dutch Corporate Income Tax Act 1969 or (iii) that are redeemable in exchange for, convertible into or linked to shares or other equity instruments issued or to be issued by PGF or by any entity related to PGF.  

If withholding is required by law, additional amounts may be payable. See “Description of the Notes—Covenants―Additional Amounts.”

Dutch Gift and Inheritance Taxes

No Dutch gift or inheritance taxes are due in respect of any gift of Notes by, or inheritance of the Notes on the death of a holder, except if:

(i)          at the time of the gift or death of the holder, the holder is a resident, or is deemed to be a resident, of The Netherlands;

(ii)         the holder dies within 180 days after the date of the gift of the Notes and is not, or not deemed to be, at the time of the gift, but is, or deemed to be, at the time of his death, a resident of The Netherlands; or

(iii)        the gift of the Notes is made under a condition precedent and the holder is a resident.

For purposes of Dutch gift and inheritance taxes, among others, a person that holds Dutch nationality will be deemed to be resident in The Netherlands if such person has been resident in The Netherlands at any time during the 10 years preceding the date of the gift or his/her death. Additionally, for purposes of Dutch gift tax, among others, a person not holding Dutch nationality will be deemed to be resident in The Netherlands if such person has been resident in The Netherlands at any time during the 12 months preceding the date of the gift. Applicable tax treaties may override deemed residency

Other Taxes and Duties

No other Dutch taxes, including turnover tax and taxes of a documentary nature, such as capital tax, stamp or registration tax or duty, are payable in The Netherlands by or on behalf of a holder of the Notes by reason only of the purchase, ownership and disposal of the Notes.

The Directive

Under the Directive", each Member State is required to provide to the tax authorities of another Member State details of payments of interest or other similar income paid or secured by a person within its jurisdiction to, or collected by such a person for, an individual resident in that other Member State or certain limited types of entities established in that other Member State.  However, for a transitional period, Austria may instead apply a withholding system with respect to such payments, deducting tax at a rate of 35%.

A number of non-EU countries, including Switzerland, and certain dependent or associated territories of certain Member States, have adopted similar measures (either provision of information or transitional withholding) with respect to payments made by a person within its jurisdiction to, or collected by such a person for, an individual 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 with respect to payments made by a person in a Member State to, or collected by such a person for, an individual resident in one of those territories.

On 24 March 2014, the Council of the European Union adopted Council Directive 2014/48/EU, or "Amending Directive", amending and broadening the scope of the requirements described above.  Member States are required to apply these new requirements from 1 January 2017.  The changes will expand the range of payments covered by the Directive, in particular to include additional types of income payable on securities.  The Directive will also expand the circumstances in which payments that indirectly benefit an individual resident in a Member State must be reported.  This approach will apply to payments made to, or secured for, persons, entities or legal arrangements (including trusts) where certain conditions are satisfied, and may in some cases apply where the person, entity or arrangement is established or effectively managed outside of the European Union.

However, the European Commission has proposed the repeal of the Directive from 1 January 2017 in the case of Austria and from 1 January 2016 in the case of all other Member States (subject to on-going requirements to fulfill administrative obligations such as the reporting and exchange of information relating to, and accounting for withholding taxes on, payments made before those dates). This is to prevent overlap between the Savings Directive and a new automatic exchange of information regime to be implemented under Council Directive 2011/16/EU on Administrative Cooperation in the Field of Taxation (as amended by Council Directive 2014/107/EU). The proposal also provides that, if it proceeds, Member States will not be required to apply the new requirements of the Amending Directive.

You should consult your advisers concerning the impact of the Directive. Should the issuer, the principal paying agent or any institution where the Notes are deposited be required to withhold any amount as a direct or indirect consequence of the Directive, then, there is no requirement for the issuer to pay any additional amounts relating to such withholding.

Holders of Notes who are individuals should note that the issuer will not pay additional amounts with respect to any withholding tax imposed as a result of the Directive.

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 PGF is a private company with limited liability incorporated under the laws of The Netherlands. A substantial portion of the assets of Petrobras and PGF are located outside the Unites States, and at any time all of their respective 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.

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The consolidated financial statements as of and for the years ended December 31, 2014, 2013 and 2012 and management’s assessment of the effectiveness of internal control over financial reporting (which is included in Management’s Report on Internal Control over Financial Reporting) incorporated in this prospectus supplement by reference to the Annual Report on Form 20-F for the year ended December 31, 2014 have been so incorporated in reliance on the report (which contains an explanatory paragraph stating that as discussed in Note 3 to the financial statements, Petrobras wrote off U.S.$2,527 million of overpayments on the acquisition of property plant and equipment incorrectly capitalized according to testimony obtained from Brazilian criminal investigations and contains an adverse opinion on the effectiveness of internal control over financial reporting) of PricewaterhouseCoopers Auditores Independentes, an independent registered public accounting firm given on the authority of that firm as experts in auditing and accounting.

With respect to the unaudited interim financial information of Petrobras as of March 31, 2015 and for the three-month periods ended March 31, 2015 and 2014, incorporated by reference herein, PricewaterhouseCoopers Auditores Independentes reported that they have applied limited procedures in accordance with professional standards for a review of such information. However, their separate report included in the Petrobras Form 6-K furnished to the SEC on May 18, 2015, and incorporated by reference herein, states that they did not audit and they do not express an opinion on that unaudited interim financial information. Accordingly, the degree of reliance on their report on such information should be restricted in light of the limited nature of the review procedures applied. PricewaterhouseCoopers Auditores Independentes is not subject to the liability provisions of Section 11 of the Securities Act for their report on the unaudited financial information because that report is not a “report” or a “part” of the registration statement prepared or certified by PricewaterhouseCoopers Auditores Independentes within the meaning of Sections 7 and 11 of the Securities Act.
