MME	The federal Ministry of Mines and Energy, or MME.
NGLs	Natural gas liquids, which are light hydrocarbon substances produced with natural gas, which condense into liquid at normal temperature and pressure.
Oil	Crude oil, including NGLs and condensates.
Pre-salt reservoir	A geological formation containing oil or natural gas deposits located beneath an evaporitic layer.
Post-salt reservoir	A geological formation containing oil or natural gas deposits located above an evaporitic layer.
Proved reserves	Consistent with the definitions in the SEC’s Amended Rule 4-10(a) of Regulation S-X, proved oil and gas reserves are those quantities of oil and gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible – from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations.  Existing economic conditions include prices and costs at which economic producibility from a reservoir is to be determined.  The price is the average price during the 12-month period prior to December 31, 2010, unless prices are defined by contractual arrangements, excluding escalations based upon future conditions.  The project to extract the hydrocarbons must have commenced or we must be reasonably certain that we will commence the project within a reasonable time. Reserves which can be produced economically through application of improved recovery techniques (such as fluid injection) are included in the “proved” classification when successful testing by a pilot project, or the operation of an installed program in the reservoir, provides support for the engineering analysis on which the project or program was based.
Proved developed reserves.	Proved developed reserves are reserves that can be expected to be recovered: (i) through existing wells with existing equipment and operating methods or in which the cost of the required equipment is relatively minor compared to the cost of a new well; and (ii) through installed extraction equipment and infrastructure operational at the time of the reserves estimate if the extraction is by means not involving a well.

Table of Contents

Proved undeveloped reserves	Proved undeveloped reserves are reserves that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion.  Reserves on undrilled acreage are limited to those directly offsetting development spacing areas that are reasonably certain of production when drilled, unless evidence using reliable technology exists that establishes reasonable certainty of economic producibility at greater distances. Undrilled locations are classified as having undeveloped reserves only if a development plan has been adopted indicating that they are scheduled to be drilled within five years, unless the specific circumstances justify a longer time.  Proved undeveloped reserves do not include reserves attributable to any acreage for which an application of fluid injection or other improved recovery technique is contemplated, unless such techniques have been proved effective by actual projects in the same reservoir or an analogous reservoir or by other evidence using reliable technology establishing reasonable certainty.
SS	Semi-submersible unit.
Synthetic oil and synthetic gas	A mixture of hydrocarbons derived by upgrading (i.e., chemically altering) natural bitumen from oil sands, kerogen from oil shales, or processing of other substances such as natural gas or coal.  Synthetic oil may contain sulfur or other non-hydrocarbon compounds and has many similarities to crude oil.
TLWP	Tension Leg Wellhead Platform.
Total depth	Total depth of a well, including vertical distance through water and below the mudline.
Ultra-deep water	Over 1,500 meters (4,921 feet) deep.

PRESENTATION OF FINANCIAL INFORMATION

In this annual report, references to “real,” “reais” or “R$” are to Brazilian reais and references to “U.S. dollars” or “U.S.$” are to the United States dollars.  Certain figures included in this annual report have been subject to rounding adjustments; accordingly, figures shown as totals in certain tables may not be an exact arithmetic aggregation of the figures that precede them.

Petrobras

The audited consolidated financial statements of Petrobras and our consolidated subsidiaries as of December 31, 2010 and 2009, and for each of the three years in the period ended December 31, 2010, and the accompanying notes, contained in this annual report have been presented in U.S. dollars and prepared in accordance with U.S. generally accepted accounting principles, or U.S. GAAP.  See Item 5. “Operating and Financial Review and Prospects” and Note 2(a) to our audited consolidated financial statements.  U.S. GAAP differs in certain respects from International Financial Reporting Standards (IFRS), as issued by the International Financial Reporting Standards Board (IASB) and applied by Petrobras in its statutory financial statements prepared in accordance with Brazilian Corporate Law and regulations promulgated by the Brazilian Securities and Exchange Commission (CVM).  Brazilian Corporate Law was amended in 2007 to permit accounting practices adopted in Brazil (Brazilian GAAP) to converge with IFRS.  We have prepared our consolidated financial statements, in reais, in accordance with IFRS beginning with the three-month period ended March 31, 2010.  We are currently evaluating the possibility of discontinuing U.S. GAAP reporting and adopting IFRS as issued by the IASB as the basis for the audited consolidated financial statements contained in our annual report on Form 20-F for the year ended December 31, 2011.

Our functional currency is the Brazilian real.  As described more fully in Note 2(a) to our audited consolidated financial statements, the U.S. dollar amounts as of the dates and for the periods presented in our audited consolidated financial statements have been recalculated or translated from the real amounts in accordance with the criteria set forth in Accounting Standard Codification – ASC Topic 830 – Foreign Currency Matters.  U.S. dollar amounts presented in this annual report have been translated from reais at the period-end exchange rate for balance sheet items and the average exchange rate prevailing during the period for income statement and cash flow items.

Unless the context otherwise indicates:

•historical data contained in this annual report that were not derived from the audited consolidated financial statements have been translated from reais on a similar basis;

•forward-looking amounts, including estimated future capital expenditures, have all been based on our Petrobras 2020 Strategic Plan, which covers the period from 2009 to 2020, and on our 2010-2014 Business Plan, and have been projected on a constant basis and have been translated from reais  at an estimated average exchange rate of R$1.78 to U.S.$1.00, in accordance with our 2010-2014 Business Plan.  In addition, in accordance with our 2010-2014 Business Plan and our 2011 Annual Business Plan, future calculations involving an assumed price of crude oil have been calculated using a Brent crude oil price of U.S.$93 per barrel for 2011, U.S.$82 per barrel for 2012, U.S.$82 per barrel for 2013, U.S.$82 per barrel for 2014 and U.S.$82 per barrel for 2015 adjusted for our quality and location differences, unless otherwise stated; and

•estimated future capital expenditures are based on the most recently budgeted amounts, which may not have been adjusted to reflect all factors that could affect such amounts.

PifCo

PifCo’s functional currency is the U.S. dollar.  Substantially all of PifCo’s sales are made in U.S. dollars and all of its debt is denominated in U.S. dollars.  Accordingly, PifCo’s audited consolidated financial statements as of December 31, 2010 and 2009, and for each of the three years in the period ended December 31, 2010, and the accompanying notes contained in this annual report have been presented in U.S. dollars and prepared in accordance with U.S. GAAP and include PifCo’s wholly owned subsidiaries: Petrobras Europe Limited (PEL), Petrobras Finance Limited (PFL), Bear Insurance Company Limited (BEAR) and Petrobras Singapore Private Limited (PSPL).

RECENT DEVELOPMENTS

Global Offering of Shares

On September 29, 2010, we issued 2,293,907,960 common shares, including common shares in the form of American Depositary Shares (ADSs), and 1,788,515,136 preferred shares, including preferred shares in the form of ADSs, in a global public offering consisting of a registered offering in Brazil and an international offering, which included a registered offering in the United States. On October 1, 2010, we issued an additional 75,198,838 common shares (including common shares in the form of ADSs) and 112,798,256 preferred shares (including preferred shares in the form of ADSs) pursuant to the exercise of the underwriters’ over-allotment option. The aggregate proceeds of the global offering to us, after underwriting discounts and commissions and including the exercise of the underwriters’ over-allotment option, was approximately U.S.$70 billion. We applied the net proceeds from the global offering to pay the initial purchase price under the Assignment Agreement described below and to continue to develop all of our business segments in accordance with Petrobras’ 2010-2014 Business Plan.

Assignment Agreement (Cessão Onerosa) 

On September 3, 2010, we entered into an agreement with the Brazilian federal government (the Assignment Agreement), under which the government assigned to us the right to conduct activities for the exploration and production of oil, natural gas and other fluid hydrocarbons in specified pre-salt areas, subject to a maximum production of five billion barrels of oil equivalent. For further information on the Assignment Agreement, see Item 10. “Material contracts—Petrobras—Assignment Agreement.”

PRESENTATION OF INFORMATION CONCERNING RESERVES

Petrobras continues to utilize the SEC rules for estimating and disclosing oil and gas reserve quantities included in this annual report.  In accordance with these rules, adopted by Petrobras at year-end 2009, the year-end 2010 and 2009 reserve volumes have been estimated using the average prices calculated as the unweighted arithmetic average of the first-day-of-the-month price for each month within the 12-month period prior to the end of the reporting period include non-traditional reserves, such as synthetic oil and gas.  Year-end 2008 reserve volumes were estimated using year-end prices.  In addition, the amended rules also adopted a reliable technology definition that permits reserves to be added based on field-tested technologies.  The adoption of the SEC’s rules for estimating and disclosing oil and gas reserves and the FASB’s issuance of the Accounting Standards Update No. 2010-03 “Oil and Gas Reserve Estimation and Disclosure” in December 2010 generated no material impact on our reported reserves or on our consolidated financial position or results of operations.  DeGolyer and MacNaughton (D&M) provided estimates of most of our net domestic reserves as of December 31, 2010.  D&M also provided estimates of most of our net international reserves where we are the operator as of December 31, 2010.  All reserve estimates involve some degree of uncertainty. See Item 3. “Key Information—Risk Factors—Risks Relating to Our Operations” for a description of the risks relating to our reserves and our reserve estimates.

On January 14, 2011, we filed reserve estimates for Brazil with the ANP, in accordance with Brazilian rules and regulations, totaling 12.91 billion barrels of crude oil and condensate and 14.24 trillion cubic feet of natural gas.  The reserve estimates filed with the ANP and those provided herein differ by approximately 25.9%.  This difference is due to: (i) the ANP requirement to estimate proved reserves through the technical-economical abandonment of production wells, as opposed to limiting reserve estimates to the life of the concession contracts as required by Rule 4-10 of Regulation S-X; and (ii) different technical criteria for booking proved reserves, including the use of current oil prices as opposed to the SEC requirement that the 12-month average price be used to determine the economic producibility of reserves in Brazil.

We also file reserve estimates from our international operations with various governmental agencies under the guidelines of the Society of Petroleum Engineers, or SPE.  The aggregate reserve estimates from our international operations, under SPE guidelines, amounted to 0.47 billion barrels of crude oil and NGLs and 1,406 billion cubic feet of natural gas, which is approximately 15% higher than the reserve estimates calculated under Regulation S-X, as provided herein.  This difference occurs because of different technical criteria for booking proved reserves, including the use of current oil prices as opposed to the SEC requirement that the 12-month average price be used to determine the economic producibility of international reserves.  In addition, we have not yet included all volumes from the Gulf of Mexico fields because there is no production history available for analogous reservoirs.

RISK FACTORS

Risks Relating to Our Operations

Exploration and production of oil in deep and ultra-deep waters involves risks.

Exploration and production of oil involves risks that are increased when carried out in deep and ultra-deep waters. The majority of our exploration and production activities are carried out in deep and ultra-deep waters, and the proportion of our deepwater activities will remain constant or increase due to the location of our pre-salt reservoirs in deep and ultra-deep waters. Our activities, particularly deep and ultra-deep water drilling, present several risks such as the risk of spills, explosions in platforms and drilling operations and natural disasters. The occurrence of any of these events or other incidents could result in personal injuries, loss of life, severe environmental damage with the resulting containment, clean-up and repair expenses, equipment damage and liability in civil and administrative proceedings.

Our insurance policies do not cover all liabilities, and insurance may not be available for all risks. There can be no assurance that incidents will not occur in the future, that insurance will adequately cover the entire scope or extent of our losses or that we will not be found liable in connection with claims arising from these and other events.

Substantial or extended declines and volatility in the international prices of crude oil, oil products and natural gas as well as a significant depreciation of the real in relation to the U.S. dollar may have a material adverse effect on us.

The majority of our revenue is derived primarily from sales of crude oil and oil products and, to a lesser extent, natural gas.  We do not, and will not, have control over the factors affecting international prices for crude oil, oil products and natural gas.  Changes in crude oil prices typically result in changes in prices for oil products and natural gas.  Historically, international prices for crude oil, oil products and natural gas have fluctuated widely as a result of many factors.  These factors include:

•global and regional economic and geopolitical developments in crude oil producing regions, particularly in the Middle East;

•the ability of the Organization of Petroleum Exporting Countries (OPEC) to set and maintain crude oil production levels and defend prices;

•global and regional supply and demand for crude oil, oil products and natural gas;

•global financial crises, such as the global financial crisis of 2008;

•competition from other energy sources;

•domestic and foreign government regulations; and

•weather conditions.

Volatility and uncertainty in international prices for crude oil, oil products and natural gas may continue.  Substantial or extended declines in international crude oil prices may have a material adverse effect on our business, results of operations and financial condition, and the value of our proved reserves.  Significant decreases in the price of crude oil may cause us to reduce or alter the timing of our capital expenditures, and this could adversely affect our production forecasts in the medium term and our reserve estimates in the future.  In addition, our pricing policy in Brazil is intended to be at parity with international product prices over the long term.  In general we do not adjust our prices for diesel, gasoline and LPG during periods of volatility in the international markets.  As a result, material rapid or sustained increases in the international price of crude oil and oil products may result in reduced downstream margins for us, and we may not realize all the gains that our competitors realize in periods of higher international prices.  We are also exposed to this risk during periods of depreciation of the real

in relation to the U.S. dollar, as we sell oil and oil products in Brazil in reais and international prices for crude oil and oil products are set in U.S. dollars. A depreciation of the real reduces our prices in U.S. dollar terms and may lead to reduced margins in U.S. dollars.

Our ability to maintain our long-term growth objectives for oil production depends on our ability to successfully develop our reserves, and failure to do so could prevent us from achieving our long-term goals for growth in production.

Our ability to maintain our long-term growth objectives for oil production, including those defined in our 2010-2014 Business Plan, is highly dependent upon our ability to successfully develop our existing reserves and, in the long term, upon our ability to obtain additional reserves.  The development of the sizable reservoirs in deep and ultra-deep waters, including the pre-salt reservoirs that have been assigned to us by the Brazilian federal government, has demanded and will continue to demand significant capital investments.  A primary operational challenge, particularly for the pre-salt, will be allocating our resources to build the necessary infrastructure at considerable distances from the shore and securing qualified labor force and offshore oil services to develop reservoirs of such size and magnitude in a timely manner, a challenge that is particularly heightened by the fact that we are required to acquire a minimum level of goods and services from Brazilian providers.  We cannot guarantee that we will have or will be able to obtain, in the time frame that we expect, sufficient resources for the installation of infrastructure, hiring of qualified labor force and provisioning of offshore oil services necessary to exploit the reservoirs in deep and ultra-deep waters that the Brazilian federal government has licensed and assigned to us, or that it may license to us in the future, including as a result of the enactment of the new regulatory model for the oil and gas industry in Brazil.

Our exploration activities also expose us to the inherent risks of drilling, including the risk that we will not discover commercially productive crude oil or natural gas reserves.  The costs of drilling wells are often uncertain, and numerous factors beyond our control (such as unexpected drilling conditions, equipment failures or incidents, and shortages or delays in the availability of drilling rigs and the delivery of equipment) may cause drilling operations to be curtailed, delayed or cancelled.  These risks are heightened when we drill in deep and ultra-deep water.  In addition, increased competition in the oil and gas sector in Brazil may increase the costs of obtaining additional reservoirs in bidding rounds for new concessions.  We may not be able to maintain our long-term growth objectives for oil production unless we conduct successful exploration and development activities of our large reservoirs in a timely manner.

We may not obtain, or it may be difficult for us to obtain, financing for our planned investments, which may have a material adverse effect on us.

Under our 2010-2014 Business Plan, we intend to invest U.S.$224 billion between 2010 and 2014.  This amount does not include our funding requirements to acquire our rights under the Assignment Agreement or the capital expenditures that will be required to explore and develop the areas covered by the Assignment Agreement.  In order to implement our 2010-2014 Business Plan, including the development of our oil and natural gas exploration activities in the pre- and post-salt layers and the development of refining capacity sufficient to process increasing production volumes, we will need to raise significant amounts of debt capital in the financial and capital markets, including by, among other means, loans and issuing debt securities.  We cannot guarantee that we will be able to obtain the necessary financing in a timely and advantageous manner in order to implement our 2010-2014 Business Plan.

The Brazilian federal government maintains control over our investment budget and establishes limits on our investments and long-term debt.  As a state-controlled entity, we must submit our budget for approval every year to the Ministry of Planning, Budget and Management, the MME and the Brazilian Congress.  Our approved budget may not be sufficient to make all of the investments that we envision, and may prevent us from acquiring additional indebtedness in a certain fiscal year. In this case, if we are not able to obtain financing at reasonable terms and conditions that do not require approval by the Brazilian federal government and the Brazilian Congress, we may not be able to complete all or part of our planned investments, including those we have agreed to make to develop our oil and natural gas exploration activities, which will adversely affect our business.

Table of Contents

Our crude oil and natural gas reserve estimates involve some degree of uncertainty, which could adversely affect our ability to generate income. 

The proved crude oil and natural gas reserves set forth in this annual report are our estimated quantities of crude oil, natural gas and natural gas liquids that geological and engineering data demonstrate with reasonable certainty to be recoverable from known reservoirs under existing economic and operating conditions (i.e., prices and costs as of the date the estimate is made) according to applicable regulations.  Our proved developed crude oil and natural gas reserves are reserves that can be expected to be recovered through existing wells with existing equipment and operating methods.  There are uncertainties in estimating quantities of proved reserves related to prevailing crude oil and natural gas prices applicable to our production, which may lead us to make revisions to our reserve estimates.  Downward revisions in our reserve estimates could lead to lower future production, which could have an adverse effect on our results of operations and financial condition.

We do not own any of the subsoil accumulations of crude oil and natural gas in Brazil.

Access to crude oil and natural gas reserves is essential to an oil and gas company’s sustained production and generation of income.  Under Brazilian law, the Brazilian federal government owns all subsoil accumulations of crude oil and natural gas in Brazil and the concessionaire owns the oil and gas it produces from those subsoil accumulations pursuant to concession agreements.  We possess the exclusive right to develop the volumes of crude oil and natural gas included in our reserves pursuant to concession agreements awarded to us by the Brazilian federal government and we own the hydrocarbons we produce under those concession agreements.  Our ability to generate income would be adversely affected if the Brazilian federal government were to restrict or prevent us from exploiting these crude oil and natural gas reserves.  In addition, we may be subject to fines by the ANP and our concessions may be revoked if we do not comply with our obligations under our concessions.

The new regulatory model for the oil and gas industry in Brazil and the Assignment Agreement may be challenged in Brazilian courts.

The new regulatory model for the oil and gas industry in Brazil, enacted in 2010, establishes new rules for the exploration and production of oil and natural gas in the pre-salt areas in Brazil.  See Item 4. “Information on the Company—Regulation of the Oil and Gas Industry in Brazil—Current Regulatory Framework.” The assignment agreement we entered into with the Brazilian federal government on September 3, 2010 (Assignment Agreement), under which the government assigned to us exploration and production rights to oil, natural gas and other fluid hydrocarbons in pre-salt areas not under concession, of 5 billion barrels of oil equivalent, is a separate law that was also approved by Congress and enacted in 2010.

Challenges to the constitutionality or legality of the new regulatory model for the oil and gas industry in Brazil, including challenges to the Assignment Agreement, may be brought before the Brazilian Supreme Court (Supremo Tribunal Federal, or STF) or the Brazilian Superior Court of Justice (Superior Tribunal de Justiça, or STJ).  Challenges to the constitutionality or legality of the new regulatory model may relate to our status as the exclusive operator in all pre-salt areas not yet under concession, in addition to other areas that the CNPE may deem strategic, and the fact that exploration and production rights in such areas will be granted to us without a public bidding process. Challenges to the constitutionality or legality of the Assignment Agreement may relate to the direct award of exploration and production rights to us without a public bidding, contract price paid for the transfer of rights or the conditions, methodologies and results arising from the revision process pursuant to the terms of the Assignment Agreement.  If the new regulatory model for the oil and gas industry in Brazil, including the Assignment Agreement, is determined to be wholly or partly unconstitutional or illegal, uncertainties about the regulation of the oil and gas sector in which we operate may arise, including questions about the validity of the legal relationships that are based on the new regulatory model, including the rights acquired under the Assignment Agreement.

20

In addition, we cannot assure you that the price paid for the transfer of rights will not be challenged.  We and our directors may be the subject of legal proceedings questioning the approval and the execution of the Assignment Agreement as being detrimental to the interests of our non-controlling shareholders.

We do not know whether a challenge to the constitutionality or legality of the new regulatory model for the oil and gas industry in Brazil, including the Assignment Agreement, will arise, nor can we predict, in the event it does arise, the outcome of any such legal proceeding.

The Assignment Agreement we entered into with the Brazilian federal government is a related party transaction.

The transfer of oil and gas exploration and production rights to us related to specific pre-salt areas is governed by the Assignment Agreement, which is a contract between the Brazilian federal government, our controlling shareholder, and us. The negotiation of the Assignment Agreement involved significant issues, including negotiations regarding (1) the area covered by the transfer of rights, consisting of exploratory blocks; (2) the volume, on a barrels of oil equivalent basis, that we may extract from this area; (3) the price to be paid for the transfer of rights; (4) the terms of the subsequent revision of the contract price and volume under the Assignment Agreement; and (5) the terms providing for the reallocation of volumes among the exploratory blocks assigned to us.  This contract includes provisions for a subsequent revision of the contract terms, which are subject to oil and industry prices at the time the revision is made.  Once the revision process is concluded pursuant to the terms of the Assignment Agreement, if it is determined that the revised contract price is higher than the initial contract price, we will either make an additional payment to the Brazilian federal government or reduce the amount of barrels of oil equivalent subject to the Assignment Agreement. If it is determined, on the other hand, that the revised contract price is lower than the initial contract price, the Brazilian federal government will make a payment to us.  This will require a negotiation with the Brazilian federal government pursuant to the terms of the Assignment Agreement.

The Assignment Agreement provides for the reallocation of volumes among the exploratory blocks assigned to us if oil and gas production is deemed economically unviable in one or more blocks for geologic reasons that would prevent the fulfillment of the Assignment Agreement as a result of the revision process.  Such reallocation would result in a revision of the volume of barrels of oil equivalent we would have to produce per block, which could prevent us from producing the maximum amount of barrels of oil equivalent contemplated under the Assignment Agreement.  In the event that we cannot produce such maximum amount, the Brazilian federal government has contractually undertaken the obligation to compensate us for the volumes not produced pursuant to the terms of the Assignment Agreement. 

Over the course of the life of the Assignment Agreement, novel issues may arise in the implementation of the revision process and reallocation provisions that will require negotiations between related parties.

We are subject to numerous environmental and health regulations that have become more stringent in the recent past and may result in increased liabilities and increased capital expenditures.

Our activities are subject to a wide variety of federal, state and local laws, regulations and permit requirements relating to the protection of human health and the environment, both in Brazil and in other jurisdictions in which we operate.  Particularly in Brazil, our oil and gas business is subject to extensive regulation by several governmental agencies, including the ANP, the ANEEL, the Brazilian Water Transportation Agency (Agência Nacional de Transportes Aquaviários) and the Brazilian Land Transportation Agency (Agência Nacional de Transportes Terrestres). 

Failure to observe or comply with these laws and regulations could result in penalties that could adversely affect our operations.  In Brazil, for example, we could be exposed to administrative and criminal sanctions, including warnings, fines and closure orders for non-compliance with these environmental regulations, which, among other things, limit or prohibit emissions or spills of toxic substances produced in connection with our operations.  Waste disposal and emissions regulations may also require us to clean up or retrofit our facilities at substantial cost and could result in substantial liabilities.  The Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis (Brazilian Institute of the Environment and Renewable Natural Resources, or IBAMA) and the ANP routinely inspect our facilities, and may impose fines, restrictions on operations, or other sanctions in connection with its inspections.  In addition, we are subject to environmental laws that require us to incur significant costs to cover damage that a project may cause to the environment.  These additional costs may have a negative impact on the profitability of the projects we intend to implement or may make such projects economically unfeasible.

21

As environmental regulations become more stringent, and as new laws and regulations relating to climate change, including carbon controls, become applicable to us, it is probable that our capital expenditures for compliance with environmental regulations and to effect improvements in our health, safety and environmental practices will increase substantially in the future.  We cannot guarantee that we will be able to maintain or renew our licenses and permits if they are revoked or if the applicable environmental authorities oppose or delay their issuance or renewal.  Increased expenditures to comply with environmental regulations, mitigate the environmental impact of our operations or restore the biological and geological characteristics of the areas in which we operate may result in reductions in other strategic investments.  Any substantial increase in expenditures for compliance with environmental regulations or reduction in strategic investments may have a material adverse effect on our results of operations or financial condition.

We may incur losses and spend time and money defending pending litigations and arbitrations.

We are currently a party to numerous legal proceedings relating to civil, administrative, environmental, labor and tax claims filed against us.  These claims involve substantial amounts of money and other remedies. Several individual disputes account for a significant part of the total amount of claims against us, including a tax dispute amounting to approximately U.S.$2.7 billion.  See Item 8. “Financial Information—Legal Proceedings.”  In the event that claims involving a material amount and for which we have no provisions were to be decided against us, or in the event that the losses estimated turn out to be significantly higher than the provisions made, the aggregate cost of unfavorable decisions could have a material adverse effect on our financial condition and results of operations.  We may also be subject to litigation and administrative proceedings in connection with our concessions and other government authorizations, which could result in the revocation of such concessions and government authorizations.  In addition, our management may be required to direct its time and attention to defending these claims, which could preclude them from focusing on our core business.  Depending on the outcome, certain litigation could result in restrictions on our operations and have a material adverse effect on certain of our businesses.

We are vulnerable to increased financing expenses resulting from increases in prevailing market interest rates and exchange rate fluctuation.

As of December 31, 2010, approximately 60.3% — U.S.$41,462 million of our total indebtedness — consisted of floating rate debt.  In light of cost considerations and market analysis, we decided not to enter into derivative contracts or make other arrangements to hedge against the risk of an increase in interest rates.  Accordingly, if market interest rates (principally LIBOR) rise, our financing expenses will increase, which could have an adverse effect on our results of operations and financial condition.

Fluctuations in exchange rates, especially a depreciation of the real  in relation to the U.S. dollar rate, may also increase our financing expenses as most of our revenues have been denominated in reais, while some of our operating expenses and capital expenditures and a substantial portion of our indebtedness are, and are expected to continue to be, denominated in or indexed to U.S. dollars and other foreign currencies.

22

We are not insured against business interruption for our Brazilian operations and most of our assets are not insured against war or sabotage.

We do not maintain coverage for business interruptions of any nature for our Brazilian operations, including business interruptions caused by labor action.  If, for instance, our workers were to strike, the resulting work stoppages could have an adverse effect on us.  In addition, we do not insure most of our assets against war or sabotage.  Therefore, an attack or an operational incident causing an interruption of our business could have a material adverse effect on our financial condition or results of operations.

We are subject to substantial risks relating to our international operations.

We operate in several countries, particularly in South America and West Africa, that can be politically, economically and socially unstable.  The results of operations and financial condition of our subsidiaries in these countries may be adversely affected by fluctuations in their local economies, political instability and governmental actions relating to the economy, including:

•the imposition of price controls;

•the imposition of restrictions on hydrocarbon exports;

•the fluctuation of local currencies against the real; 

•the nationalization of oil and gas reserves;

•increases in export tax and income tax rates for crude oil and oil products; and

•unilateral (governmental) institutional and contractual changes, including controls on investments and limitations on new projects.

If one or more of the risks described above were to materialize we may lose part or all of our reserves in the affected country and we may not achieve our strategic objectives in these countries or in our international operations as a whole, which may result in a material adverse effect on our results of operations and financial condition.  For more information about our operations outside Brazil, see Item 4. “Information on the Company¾International.” 

Risks Relating to PifCo

PifCo’s operations and debt servicing capabilities are dependent on us.

PifCo’s financial position and results of operations are directly affected by our decisions.  PifCo is a direct wholly owned subsidiary of Petrobras incorporated in the Cayman Islands as an exempted company with limited liability.  Currently, PifCo purchases crude oil and oil products from third parties and sells them to us.  PifCo also purchases crude oil and oil products from us and sells them outside Brazil.  Accordingly, intercompany activities and transactions, and therefore PifCo’s financial position and results of operations, are affected by decisions made by us.  Additionally, PifCo sells and purchases crude oil and oil products to and from third parties and related parties, mainly outside Brazil.  Commercial operations are carried out under market conditions and at market prices.

PifCo is gradually reducing its sales of crude oil and oil products to us and will gradually reduce its sales of crude oil and oil products to third parties, and will eventually cease these commercial operations altogether.  At that time, PifCo will become a finance subsidiary functioning as a vehicle for us to raise capital for our operations outside of Brazil through the issuance of debt securities in the international capital markets, among other means.  PifCo’s ability to service and repay its indebtedness is consequently dependent on our own operations.  Financing for PifCo’s commercial operations is provided by us, as well as third-party credit providers in favor of whom we provide credit support.  Our support of PifCo’s debt obligations has been and will continue to be made through unconditional and irrevocable guaranties of payment.

23

Our own financial condition and results of operations, as well as our financial support of PifCo, directly affect PifCo’s operational results and debt servicing capabilities.  For a more detailed description of certain risks that may have a material adverse impact on our financial condition or results of operations and therefore affect PifCo’s ability to meet its debt obligations, see “Risks Relating to Our Operations.”

PifCo depends on us to service its indebtedness to third parties.

PifCo is gradually reducing its sales of crude oil and oil products to us and will gradually reduce its sales of crude oil and oil products to third parties and will eventually cease these commercial operations altogether, as described above.  PifCo regularly incurs indebtedness and will continue to do so as our finance subsidiary.  PifCo depends, and will continue to depend, on financing and credit support from us to service its indebtedness to third parties.  All such indebtedness has the benefit of a guaranty or other equivalent credit support from us.  If for any reason we are not permitted to continue to finance PifCo’s operations or continue to provide credit support to the indebtedness it incurs, this would have a materially adverse effect on PifCo’s ability to meet its debt obligations.

Risks Relating to Our Relationship with the Brazilian Federal Government

The Brazilian federal government, as our principal shareholder, may cause us to pursue certain macroeconomic and social objectives that may have a material adverse effect on us.

The Brazilian federal government, as the principal shareholder of a mixed capital company such as ours, has pursued, and may pursue in the future, certain of its macroeconomic and social objectives through us, as permitted by law.  Brazilian law requires the Brazilian federal government to own a majority of our voting stock, and so long as it does, the Brazilian federal government will have the power to elect a majority of the members of our board of directors and, through them, a majority of the executive officers who are responsible for our day-to-day management.  As a result, we may engage in activities that give preference to the objectives of the Brazilian federal government rather than to our own economic and business objectives.

In particular, we continue to assist the Brazilian federal government to ensure that the supply and pricing of crude oil and oil products in Brazil meet Brazilian consumption requirements.  Accordingly, we may make investments, incur costs and engage in sales on terms that may have an adverse effect on our results of operations and financial condition.  Prior to January 2002, prices for crude oil and oil products were regulated by the Brazilian federal government, occasionally set below prices prevailing in the world oil markets.  We cannot assure you that price controls will not be reinstated in Brazil.  

We may not be able to obtain financing for some of our planned investments, and failure to do so could adversely affect our operating results and financial condition.

The Brazilian federal government maintains control over our investment budget and establishes limits on our investments and long-term debt.  As a state-controlled entity, we must submit our proposed annual budgets to the Ministry of Planning, Budget and Management, the MME and the Brazilian Congress for approval.  If our approved budget reduces our proposed investments and incurrence of new debt and we cannot obtain financing that does not require Brazilian federal government approval, we may not be able to make all the investments we envision, including those we have agreed to make to expand and develop our crude oil and natural gas fields.  If we are unable to make these investments, our operating results and financial condition may be adversely affected.

Risks Relating to Brazil

The Brazilian federal government has historically exercised, and continues to exercise, significant influence over the Brazilian economy. Brazilian political and economic conditions have a direct impact on our business and may have a material adverse effect on us.

The Brazilian federal government’s economic policies may have important effects on Brazilian companies, including us, and on market conditions and prices of Brazilian securities.  Our financial condition and results of operations may be adversely affected by the following factors and the Brazilian federal government’s response to these factors:

•devaluations and other exchange rate movements;

•inflation; 

•exchange control policies;

•price instability;

•interest rates;

•liquidity of domestic capital and lending markets;

•tax policy;

•regulatory policy for the oil and gas industry, including pricing policy; and

•other political, diplomatic, social and economic developments in or affecting Brazil.

Uncertainty over whether the Brazilian federal government will implement changes in policy or regulations that may affect any of the factors mentioned above or other factors in the future may lead to economic uncertainty in Brazil and increase the volatility of the Brazilian securities market and securities issued abroad by Brazilian companies, which may have a material adverse effect on our results of operations and financial condition.

Risks Relating to Our Equity and Debt Securities

The size, volatility, liquidity and/or regulation of the Brazilian securities markets may curb the ability of holders of ADSs to sell the common or preferred shares underlying our ADSs.

Petrobras shares are some of the most liquid in the São Paulo Stock Exchange (BM&FBOVESPA), but overall, the Brazilian securities markets are smaller, more volatile and less liquid than the major securities markets in the United States and other jurisdictions, and may be regulated differently from the way in which U.S. investors are accustomed.  Factors that may specifically affect the Brazilian equity markets may limit the ability of holders of ADSs to sell the common or preferred shares underlying our ADSs at the price and time they desire.

The market for PifCo’s notes may not be liquid.

Some of PifCo’s notes are not listed on any securities exchange and are not quoted through an automated quotation system.  We can make no assurance as to the liquidity of or trading markets for PifCo’s notes.  We cannot guarantee that the holders of PifCo’s notes will be able to sell their notes in the future.  If a market for PifCo’s notes does not develop, holders of PifCo’s notes may not be able to resell the notes for an extended period of time, if at all.

25

Holders of ADSs may be unable to exercise preemptive rights with respect to the common or preferred shares underlying the ADSs. 

Holders of ADSs who are residents of the United States may not be able to exercise the preemptive rights relating to the common or preferred shares underlying our ADSs unless a registration statement under the Securities Act is effective with respect to those rights or an exemption from the registration requirements of the Securities Act is available.  We are not obligated to file a registration statement with respect to the common or preferred shares relating to these preemptive rights, and therefore we may not file any such registration statement.  If a registration statement is not filed and an exemption from registration does not exist, JPMorgan Chase Bank, N.A., as depositary, will attempt to sell the preemptive rights, and holders of ADSs will be entitled to receive the proceeds of the sale.  However, the preemptive rights will expire if the depositary cannot sell them.  For a more complete description of preemptive rights with respect to the common or preferred shares, see Item 10. “Additional Information—Memorandum and Articles of Association of Petrobras—Preemptive Rights.”

If holders of our ADSs exchange their ADSs for common or preferred shares, they risk losing the ability to remit foreign currency abroad and forfeiting Brazilian tax advantages.

The Brazilian custodian for our common or preferred shares underlying our ADSs must obtain a certificate of registration from the Central Bank of Brazil to be entitled to remit U.S. dollars abroad for payments of dividends and other distributions relating to our preferred and common shares or upon the disposition of the common or preferred shares.  If holders of ADSs decide to exchange their ADSs for the underlying common or preferred shares, they will be entitled to continue to rely, for five Brazilian business days from the date of exchange, on the custodian’s certificate of registration.  After that period, such holders may not be able to obtain and remit U.S. dollars abroad upon the disposition of the common or preferred shares, or distributions relating to the common or preferred shares, unless they obtain their own certificate of registration or register under Resolution No. 2,689, of January 26, 2000, of the National Monetary Council (Conselho Monetário Nacional, or CMN), which entitles registered foreign investors to buy and sell on the BM&FBOVESPA.  In addition, if such holders do not obtain a certificate of registration or register under Resolution No. 2,689, they may be subject to less favorable tax treatment on gains with respect to the common or preferred shares.

If such holders attempt to obtain their own certificate of registration, they may incur expenses or suffer delays in the application process, which could delay their ability to receive dividends or distributions relating to the common or preferred shares or the return of their capital in a timely manner.  The custodian’s certificate of registration or any foreign capital registration obtained by such holders may be affected by future legislative or regulatory changes and we cannot assure such holders that additional restrictions applicable to them, the disposition of the underlying common or preferred shares, or the repatriation of the proceeds from the process will not be imposed in the future.

Holders of ADSs may face difficulties in protecting their interests.

Our corporate affairs are governed by our bylaws and Brazilian Corporate Law, which differ from the legal principles that would apply if we were incorporated in a jurisdiction in the United States or elsewhere outside Brazil.  In addition, the rights of an ADS holder, which are derivative of the rights of holders of our common or preferred shares, as the case may be, to protect their interests against actions by our board of directors are different under Brazilian Corporate Law than under the laws of other jurisdictions.  Rules against insider trading and self-dealing and the preservation of shareholder interests may also be different in Brazil than in the United States.  There is also a less active plaintiff’s bar dedicated to the enforcement of shareholders’ rights in Brazil than in the United States.  In addition, shareholders in Brazilian companies ordinarily do not have standing to bring a class action.

We are a state-controlled company organized under the laws of Brazil and all of our directors and officers reside in Brazil. Substantially all of our assets and those of our directors and officers are located in Brazil.  As a result, it may not be possible for holders of ADSs to effect service of process upon us or our directors and officers within the United States or other jurisdictions outside Brazil or to enforce against us or our directors and officers judgments obtained in the United States or other jurisdictions outside Brazil.  Because judgments of U.S. courts for civil liabilities based upon the U.S. federal securities laws may only be enforced in Brazil if certain requirements are met, holders of ADSs may face greater difficulties in protecting their interest in actions against us or our directors and officers than would shareholders of a corporation incorporated in a state or other jurisdiction of the United States.

26

Holders of our ADSs may encounter difficulties in the exercise of voting rights and preferred shares and the ADSs representing preferred shares generally do not give holders of ADSs voting rights.

Holders of ADSs may encounter difficulties in the exercise of some of their rights as a shareholder if they hold our ADS rather than the underlying shares.  For example, if we fail to provide the depositary with voting materials on a timely basis, holders of ADSs may not be able to vote by giving instructions to the depositary on how to vote for them.

In addition, a portion of our ADSs represents our preferred shares.  Under Brazilian law and our bylaws, holders of preferred shares generally do not have the right to vote in meetings of our stockholders.  This means, among other things, that holders of ADSs representing preferred shares are not entitled to vote on important corporate transactions or decisions.  See Item 10. “Additional Information—Memorandum and Articles of Incorporation of Petrobras—Voting Rights” for a discussion of the limited voting rights of our preferred shares.

We would be required to pay judgments of Brazilian courts enforcing our obligations under the guaranty relating to PifCo’s notes only in reais.

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

A finding that we are subject to U.S. bankruptcy laws and that the guaranty executed by us were a fraudulent conveyance could result in PifCo noteholders losing their legal claim against us.

PifCo’s obligation to make payments on the PifCo notes is supported by our obligation under the corresponding guaranty.  We have been advised by our external U.S. counsel that the guaranty is valid and enforceable in accordance with the laws of the State of New York and the United States.  In addition, we have been advised by our general counsel that the laws of Brazil do not prevent the guaranty from being valid, binding and enforceable against us in accordance with its terms.  In the event that U.S. federal fraudulent conveyance or similar laws are applied to the guaranty, and we, at the time we entered into the relevant guaranty:

•were or are insolvent or rendered insolvent by reason of our entry into such guaranty;

•were or are engaged in business or transactions for which the assets remaining with us constituted unreasonably small capital; or

•intended to incur or incurred, or believed or believe that we would incur, debts beyond our 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 our obligations under the guaranty could be avoided, or claims with respect to that agreement 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 us as a result of PifCo’s issuance of these notes.  To the extent that the guaranty is held to be a fraudulent conveyance or unenforceable for any other reason, the holders of the PifCo notes would not have a claim against us under the relevant guaranty and will solely have a claim against PifCo.  We cannot assure you that, after providing for all prior claims, there will be sufficient assets to satisfy the claims of the PifCo noteholders relating to any avoided portion of the guaranty.

Item 4.                  Information on the Company

History and Development

Petróleo Brasileiro S.A.—Petrobras—was incorporated in 1953 to conduct the Brazilian federal government’s hydrocarbon activities.  We began operations in 1954 and have been carrying out crude oil and natural gas production and refining activities in Brazil on behalf of the government.

As part of a comprehensive reform of the oil and gas regulatory system, the Brazilian Congress amended the Brazilian Constitution in 1995 to authorize the Brazilian federal government to contract with any state or privately-owned company to carry out upstream, oil refining, cross-border commercialization and transportation activities in Brazil of oil, natural gas and their respective products.  On August 6, 1997, Brazil enacted Law No. 9,478, which established a concession-based regulatory framework, ended our exclusive right to carry out oil and gas activities, and allowed competition in all aspects of the oil and gas industry in Brazil.  Since that time, we have been operating in an increasingly deregulated and competitive environment.  Law No. 9,478 also created an independent regulatory agency, the ANP, to regulate the oil, natural gas and renewable fuel industry in Brazil and to create a competitive environment in the oil and gas sector.  Effective January 2, 2002, Brazil deregulated prices for crude oil, oil products and natural gas.  See “Regulation of the Oil and Gas Industry in Brazil—Price Regulation.” 

In 2010, three new laws were enacted to regulate exploration and production activities in pre-salt areas not subject to existing concessions:  Law No. 12,351, Law No. 12,304, and Law No. 12,276.  The enacted legislation does not regulate existing pre-salt concessions, which cover approximately 28% of the pre-salt region.

Pursuant to Law No. 12,276, we entered into an agreement with the Brazilian federal government on September 3, 2010 (Assignment Agreement), under which the government assigned to us the right to activities for the exploration and production of oil, natural gas and other fluid hydrocarbons in specified pre-salt areas, subject to a maximum production of five billion barrels of oil equivalent.  The initial purchase price for our rights under the Assignment Agreement was R$74,807,616,407, which was equivalent to U.S.$42,533,327,500 as of September 1, 2010.  On September 29, 2010, we issued 2,293,907,960 common shares (including common shares in the form of ADSs) and 1,788,515,136 preferred shares (including preferred shares in the form of ADSs) in a global public offering consisting of a registered offering in Brazil and an international offering that included a registered offering in the United States.  On October 1, 2010, we issued an additional 75,198,838 common shares (including common shares in the form of ADSs) and 112,798,256 preferred shares (including preferred shares in the form of ADSs) pursuant to the exercise of the underwriters’ over-allotment option.  We applied part of the net proceeds from the global offering to pay the initial purchase price under the Assignment Agreement.  In order to ensure transparency, our board of directors created a special committee comprised of minority shareholder representatives to monitor the transfer of rights transaction.  We complied with all Brazilian Corporate Law requirements in carrying out the capitalization process, including the protection of the rights of our minority shareholders. 

Our common and preferred shares have been traded on the BM&FBOVESPA since 1968.  Petrobras was incorporated as a state-controlled company under Law No. 2,004 (effective October 3, 1953), and a majority of our voting capital must be owned by the Brazilian federal government.  As of December 31, 2010, the Brazilian federal government owned 48.3% of our outstanding capital stock and 63.6% of our voting shares.  We operate through subsidiaries, joint ventures, and associated companies established in Brazil and many other countries.  Our principal executive office is located at Avenida República do Chile 65, 20031-912 Rio de Janeiro, RJ, Brazil and our telephone number is (55-21) 3224-4477.

Overview of the Group

We are an integrated oil and gas company that is the largest corporation in Brazil and one of the largest companies in Latin America in terms of revenues.  As a result of our legacy as Brazil’s former sole supplier of crude oil and oil products and our ongoing commitment to development and growth, we operate most of Brazil’s producing oil and gas fields and hold a large base of proved reserves and a fully developed operational infrastructure.  In 2010, our average domestic daily oil production was 2,004 mboe/d, an estimated 97.5% of Brazil’s total.  Over 79% of our domestic proved reserves are in large, contiguous and highly productive fields in the offshore Campos Basin, which allows us to optimize our infrastructure and limit our costs of exploration, development and production.  In 41 years of developing Brazil’s offshore basins we have developed special expertise in deepwater exploration and production, which we exploit both in Brazil and in other offshore oil provinces.

We operate substantially all the refining capacity in Brazil.  Most of our refineries are located in Southeastern Brazil, within the country’s most populated and industrialized markets and adjacent to the Campos Basin that provides most of our crude oil.  Our domestic refining capacity of 2,007 mbbl/d is well balanced with our domestic refining throughput of 1,798 mbbl/d and sales of oil products to domestic markets of 1,960 mbbl/d.  We are also involved in the production of petrochemicals.  We distribute oil products through our own “BR” network of retailers and to wholesalers.

We participate in most aspects of the Brazilian natural gas market.  We expect the percentage of natural gas in Brazil’s energy matrix to grow in the future as we expand our production of both associated and non-associated gas, mainly from offshore fields in the Campos, Espírito Santo and Santos Basins, and extend Brazil’s gas transportation infrastructure.  We use LNG terminals and import natural gas from Bolivia to meet demand and diversify our supply.  We also participate in the domestic power market primarily through our investments in gas-fired thermoelectric power plants.  In addition, we participate in the fertilizer business, which is another important source of natural gas demand. 

Outside of Brazil, we are present in more than 20 countries.  In South America, our operations extend from exploration and production to refining, marketing, retail services and natural gas pipelines.  In North America, we produce oil and gas and have refining operations in the United States.  In Africa, we produce oil in Angola and Nigeria, and in Asia, we have refining operations in Japan.  In other countries, we are engaged only in oil and gas exploration. 

Comprehensive information and tables on reserves and production is presented at the end of Item 4. See “—Additional Reserves and Production Information.”

Our activities comprise five business segments:

•Exploration and Production: oil and gas exploration, development and production in Brazil;

•Refining, Transportation and Marketing: downstream activities in Brazil, including refining, logistics, transportation, oil products and crude oil exports and imports and petrochemicals;

•Distribution: distribution of oil products to wholesalers and through our “BR” retail network in Brazil;

•Gas and Power: gas transportation and distribution, electric power generation using natural gas and renewable energy sources and fertilizer production; and

•International: exploration and production, refining, transportation and marketing, distribution and gas and power operations outside of Brazil.

Our Corporate segment comprises our financing activities not attributable to other segments, including corporate financial management, central administrative overhead and actuarial expenses related to our pension and health care plans for inactive participants.  Since 2009, our Corporate segment has included the results from our Biofuels operations.  In prior years, results from our Biofuels operations were included in our Gas and Power segment.

Oil and gas exploration and production activities in Brazil are the largest component of our portfolio.  We have gradually increased production over the past four decades, from 164 mbbl/d of crude oil, condensate and natural gas liquids in Brazil in 1970 to 2,004 mbbl/d in 2010.  We aim to grow oil and gas reserves and production sustainably and be recognized for excellence in Exploration and Production operations.

The primary focus of our E&P segment is to:

•Continue to explore and develop the Campos Basin, leveraging the current infrastructure to drill in deeper horizons in existing concessions, including pre-salt reservoirs, and using new technologies for secondary recovery in producing fields;

•Explore and develop Brazil’s two other most promising offshore basins, Espírito Santo (light oil, heavy oil and gas) and Santos (gas and light oil), with a particular focus on pre-salt development;

•Develop associated and non-associated gas resources in the Santos Basin and elsewhere to meet Brazil’s growing demand for gas and to increase the contribution of Brazilian gas production as a proportion of total domestic gas supply; and

•Sustain and increase production from onshore and shallow fields through drilling and enhanced recovery operations.

During 2010, our oil and gas production from Brazil averaged 2,165.5 mboe/d, of which 76.7% was oil and 23.3% was natural gas.  On December 31, 2010, our estimated net proved crude oil and natural gas reserves in Brazil were 12.14 billion boe, of which 86% was crude oil and 14% was natural gas.  Brazil provided 89.8% of our worldwide production in 2010 and accounted for 95% of our worldwide reserves at December 31, 2010 on a barrels of oil equivalent basis.  Historically, approximately 85% of our total Brazilian production has been oil.  In connection with the development of the pre-salt, the contribution of natural gas to total hydrocarbon production is expected to grow.  In 2010, we drilled a total of 561 development wells, of which 78 were offshore and 483 were onshore.

30

As of December 31, 2010, we had 138 exploration agreements covering 198 blocks, corresponding to a gross exploratory acreage of 130,000 km² (32.1 million acres), or a net exploratory acreage of 105,000 km² (25.9 million acres), and 31 evaluation plans.  We are exclusively responsible for conducting the exploration activities in 66 of the 138 exploration agreements.  As of December 31, 2010, we had exploration partnerships with 75 foreign and domestic companies.  We conduct exploration activities under 120 of our 138 partnership agreements. 

We focus much of our exploration effort on deepwater drilling, where the discoveries are substantially larger and our technology and expertise create a competitive advantage.  In 2010, we invested a total of U.S.$4.08 billion in exploration activities in Brazil.  We drilled a total of 116 gross exploratory wells in 2010, of which 49 were offshore and 67 onshore, with a success ratio of 57%.

Brazil’s richest oil fields are located offshore, most of them in deep waters.  Since 1971, when we started exploration in the Campos Basin, we have been active in these waters and we have become globally recognized as innovators in the technology required to explore and produce hydrocarbons in deep and ultra-deep water.  We operate more production (on a boe basis) from fields in deep and ultra-deep water than any other company.  In 2010, offshore production accounted for 87% of our production and deepwater production accounted for 76% of our production in Brazil.  In 2010, we operated 201 wells in water deeper than 1,000 meters (3,281 feet), and we drilled around 24 exploratory wells in water deeper than 1,000 meters (3,281 feet).

Offshore exploration, development and production costs are generally higher than those onshore, but we have been able to offset these higher costs by higher drilling success ratios, larger discoveries and greater production volumes.  We have historically been successful in finding and developing significant oil reservoirs offshore, which has allowed us to achieve economies of scale by spreading the total costs of exploration, development and production over a large base.  By focusing on opportunities that are close to existing production infrastructure, we limit the incremental capital requirements of new field development.

Historically, our offshore exploration and production activities were focused on post-salt reservoirs.  The discovery of the Lula field (formerly Tupi) in 2006 marked the beginning of a new chapter in our E&P history.  In recent years, we have focused our offshore exploration efforts on pre-salt reservoirs located in a region approximately 800 km (497 miles) long and 200 km (124 miles) wide stretching from the Campos to the Santos Basins.  Our existing contracts in this area cover 26.6% (approximately 45,615 km² or 11.3 million acres) of the pre-salt areas, including the pre-salt areas assigned to us under Concession Contracts and the Assignment Agreement.  An additional 4% (approximately 9,000 km² or 2.2 million acres) is under concession to other oil companies for exploration.  The remaining 69.4% (approximately 103,000 km² or 25.4 million acres) of the pre-salt region is open acreage area, not licensed yet, and the licensing of new pre-salt areas will be made under a production-sharing regime under Law No. 12,351, enacted on December 22, 2010.

Since 2005, we have drilled 52 exploratory wells as operator in this 149,000 km² (36.8 million acres) pre-salt area, 88% of which have yielded discoveries of hydrocarbon resources.  We hold interests ranging from 20% to 100% in the pre-salt exploration areas under concession to us.  In the southern part of the Santos Basin, where the salt layer is thick and the hydrocarbons have been more perfectly preserved, we have made several particularly promising discoveries since 2006, including those made in Blocks BM-S-11 (Iara, Lula and Cernambi fields) and BM-S-9 (Carioca and Guará).  In the northern part of the region, we made significant discoveries in 2008 and early 2010 in the area known as Parque das Baleias and in the Barracuda, Marlim and Caratinga fields, all of which are in the Campos Basin. As a result, we are committing substantial resources to develop these pre-salt discoveries, which are located in deep and ultra-deep waters at total depths of up to 8,000 meters (26,245 feet).

Our 2010-2014 Business Plan, which was released in June 2010 prior to the signing of the Assignment Agreement,  foresees investments of U.S.$33 billion from 2010 to 2014 (not including investments by our partners) to develop  our then-existing  concessions in the pre-salt areas, or approximately 31% of our total domestic capital expenditures for exploration and production through 2014.  In May 2011, our board of directors approved the annual revision of the Santos Basin pre-salt development plan (PLANSAL), which foresees capital expenditures of up to U.S.$73 billion through 2015 in the Santos Basin pre-salt areas, 74% of which is being provided by us and the remainder by our partners. This annual revision to the PLANSAL also provides for the development of the areas transferred to us by the Assignment Agreement while successfully reducing capital expenditures planned for the development of the Santos Basin pre-salt areas by 45% since 2008.

We have also implemented a variety of programs designed to increase oil recovery from existing fields and reduce natural declines from producing fields.

Our exploration and production activities outside Brazil are included in our International business segment.  See “—International.”

(2)                  Petrobras is not the operator in this field.

We have historically conducted exploration, development and production activities in Brazil through concession contracts, which we have obtained through participation in bid rounds conducted by the ANP.  Some of our existing concessions were granted by the ANP without an auction in 1998, as provided by Law No. 9,478.  These are known as the “Round Zero” concession contracts.  Since such time, we have participated in all of the auction rounds, most recently in December 2008.

32

Our domestic oil and gas exploration and production efforts are primarily focused on three major basins offshore in Southeastern Brazil: Campos, Espírito Santo and Santos.  The following map shows our concession areas in Brazil as of December 2010.

The Campos Basin, which covers approximately 115,000 km² (28.4 million acres), is the most prolific oil and gas basin in Brazil as measured by proved hydrocarbon reserves and annual production.  Since we began exploring this area in 1971, over 60 hydrocarbon accumulations have been discovered, including eight large oil fields in deep water and ultra-deep water.  The Campos Basin is our largest oil- and gas-producing region, producing an average 1,676.9 mbbl/d of oil and 13.6 mmm³/d (480.3 mmcf/d) of associated natural gas during 2010, 81.5% of our total production from Brazil.  In 2010 we produced oil at an average rate of 1,676.9 mbbl/d from 43 fields in the Campos Basin and held proved crude oil reserves representing 84% of our total proved crude oil reserves in Brazil.  We held proved natural gas reserves in the Campos Basin representing 48% of our total proved natural gas reserves in Brazil.  We operated 40 floating production systems, 14 fixed platforms and 6,680 km (4,151 miles) of pipeline and flexible pipes in water depths from 80 to 1,886 meters (262 to 6,188 feet), delivering oil with an average API gravity of 22.9° and an average BSW of 1%. 

We have also made important progress in pre-salt E&P activities in the Campos Basin.  In the pre-salt region of the Campos Basin, we have drilled a total of 25 wells.  In February 2010 we made a promising discovery of 28° API oil at our ultra-deep exploratory well in the Barracuda area, which followed a significant discovery of intermediate oil (30° API) in the Parque das Baleias area in November 2008.  In the Jubarte field in the Campos Basin off the coast of the State of Espírito Santo, an EWT using a single well pilot system produced at an average rate of 17 mbbl/d from September 2008 to February 2011.  We expect to accelerate pre-salt production in Parque das Baleias using existing infrastructure in the area.  We started producing from the Baleia Franca field in the second half of 2010 using the existing FPSO Capixaba.  In 2012, we expect to start up a pilot system exclusively dedicated to pre-salt exploration in the Baleia Azul region using another FPSO.

34

In 2010, the startup of operations at FPSO Capixaba located in the Cachalote field and P-57 located in the Jubarte field in the offshore Campos Basin added combined capacities of 280 mbbl/d of oil and 5.5 mmm³/d of natural gas.

We expect that future new source production from the Campos Basin will be predominantly from deepwater oil fields.  We are currently developing nine major projects in the Campos Basin:  Marlim Sul Module 3, Roncador Modules 3 and 4, Papa-Terra, Aruanã (BM-C-36) EWT and long-term production system, Jubarte Phase II, Parque das Baleias and the pre-salt reservoirs of Baleia Azul.

At December 31, 2010, we held exploration rights to 21 blocks in the Campos Basin, comprising 6,374 km² (1.5 million acres).

Espírito Santo Basin

We have made several discoveries of light oil and natural gas in the Espírito Santo Basin, which covers approximately 75,000 km² (18.5 million acres) offshore and 14,000 km² (3.5 million acres) onshore.  At December 31, 2010, we were producing oil at an average rate of 68.7 mbbl/d from 47 fields and held proved crude oil reserves representing 0.71% of our total proved crude oil reserves in Brazil.  At December 31, 2010, we were producing natural gas at an average rate of 4.2 mmm³/d (148.3 mmcf/d) and held proved natural gas reserves representing 6% of our total proved natural gas reserves in Brazil. 

In 2010, we began operations at the Canapu project served by the FPSO Cidade de Vitória with capacity to produce 2 mmm³/d (70.6 mmcf/d).

In addition to developing new production projects, we are also optimizing existing resources in the Espírito Santo area by constructing the Sul Norte Capixaba gas pipeline with capacity to transport 7 mmm³/d (247.2 mmcf/d).  The pipeline, which runs from the Parque das Baleias area to the Cacimbas gas treatment unit, is expected to come online in 2012.

On December 31, 2010, we held exploration rights to 19 blocks, three onshore and 16 offshore, comprising 8,086 km² (1.9 million acres).

Santos Basin

The Santos Basin, which covers approximately 348,900 km² (86 million acres) off the city of Santos, in the State of São Paulo, is one of the most promising exploration areas offshore Brazil and the focus of our plans to develop domestic natural gas.  In 2010, we produced oil at an average rate of 32.7 mbbl/d from two fields and one exploration area and held proved crude oil reserves representing 7% of our total proved crude oil reserves in Brazil.  Our average natural gas production in 2010 was 0.8 mmm³/d (28.3 mmcf/d) and our proved natural gas reserves in the Santos Basin represented 24% of our total proved natural gas reserves in Brazil. 

In recent years we have been carrying out plans to increase our gas production and build supporting infrastructure in the Santos and Espírito Santo Basins.  These plans are now reaching fruition, and we expect that they will increase our average gas production capacity in the Santos Basin from 0.8 mmm³/d (28.3 mmcf/d) in 2010 to 15.4 mmm³/d (543.9 mmcf/d) by the end of 2011.  In 2010 we started up post-salt operations at FPSO Cidade de Santos platform located in the Uruguá field, which produces 30 mbbl/d of light oil and is expected to produce 1 mmm³/d (35.3 mmcf/d) of gas in 2011 and as much as 7.9 mmm³/d (279.0 mmcf/d) of gas in 2012.  Mexilhão, located in shallow waters in the Santos Basin Block BS-400, is scheduled to come online in 2011 with initial production of approximately 1.9 mmm³/d (67.0 mmcf/d), potentially increasing to 9.3 mmm³/d (328.4 mmcf/d) in 2012.  An EWT at the SS-11 Atlantic Zephyr platform, located in the BM-S-40 block, also started up in 2010.  We are using the results of the EWT to develop a long-term production system for this block, including a plan to install the FPSO Cidade de Itajaí, with an expected capacity of 80 mbbl/d of oil.

The Santos Basin pre-salt was also a central focus of E&P activities in 2010.  We continue to concentrate our efforts on gathering information about the pre-salt reservoirs in the region and testing drilling technologies to improve efficiency and minimize costs in the near term.  During the next phase, which we will start in 2013, we plan to install several FPSOs in the Santos Basin pre-salt.  The subsequent phase, beginning in 2017, will include the application of improved technologies and engineering specifically designed for the pre-salt fields.

In May 2009, we initiated production in the pre-salt region of the Santos Basin with an EWT at Tupi (now called the Lula field) that has produced on average 15 mbbl/d.  In 2010, we declared the commerciality of that area, presenting development plans for the Lula and Cernambi fields and installing the first system capable of producing in the long-term at Lula, FPSO Cidade de Angra dos Reis, with a production capacity of 100 mbbl/d.  We also started the second EWT in the pre-salt region of the Santos Basin at Guará.

In 2010, we drilled eight new wells, increasing to 20 the number of wells in the pre-salt region of the Santos Basin.  We expect to start drilling up to 24 new wells in this region in 2011. 

All six blocks and one contingent block assigned to us under the Assignment Agreement are located in the pre-salt region of the Santos Basin.  We are developing these blocks in an integrated manner with the areas we already have under concession.  Over the next four years, we will move ahead with our exploration program and are targeting first oil at the Franco prospect by 2015.

On December 31, 2010, we held exploration rights to 47 blocks in the Santos Basin, comprising 29,302 km² (7.2 million acres).

Other Basins  

We produce hydrocarbons and hold exploration acreage in 19 other basins in Brazil.  Of these, the most significant are the shallow offshore Camamu Basin and the onshore Potiguar, Recôncavo, Sergipe, Alagoas and Solimões Basins.  While our onshore production is primarily in mature fields, we plan to sustain and slightly increase production from these fields in the future by using enhanced recovery methods.

We had a total of 286 production agreements as of December 31, 2010, and were the 100% owner in 256 of them.  We are operators under nine of our 30 partnership agreements.

Critical Resources in Exploration and Production

We have sought to ensure that critical service sector resources are sufficient to permit us to move ahead with our E&P plans.  Because offshore Brazil is geographically isolated from other offshore drilling areas, and because we often drill in unusually deep waters, we plan carefully for our future drilling rig needs.  By using a combination of our own rigs and units that we contract for periods of three years or longer, we have historically ensured the availability of drilling units to meet our needs, and paid lower average daily rates than if we had contracted the units on a spot basis.  We continually evaluate our need for rigs, renew our drilling contracts, contract ahead for rigs as needed, and stimulate new rig construction by signing long-term operating leases with drilling contractors for rigs that are not yet built.

In the last three years we have successfully eased pressures related to a limited supply of deepwater rigs.  Whereas in 2008 we only had three rigs capable of drilling in water depths greater than 2000 meters (6,560 feet), we had 13 as of December 31, 2010, and we expect to have 30 by 2013.  We have entered into three to ten-year contracts for 22 additional drilling rigs to engage in deepwater exploration of our offshore fields.  These rigs will arrive in Brazil and begin operations during 2011 and 2012.  Of these 22 rigs, one will have the capacity to operate in water depths of up to 1,500 meters (4,920 feet), one will have the capacity to operate in water depths of up to 1,900 meters (6,233 feet), three will be capable of operating in water depths of up to 2,000 meters (6,560 feet), seven will be capable of operating in water depths of up to 2,400 meters (7,830 feet), and 10 will be capable of drilling in water depths of up to 3,000 meters (9,840 feet).  All of these rigs will be chartered by us and have been built or are being built in shipyards outside Brazil.

In addition to these 22 new drilling rigs already contracted, we have also announced plans for 28 rigs to be built in Brazil, supporting the development of the Brazilian rig building industry so that it can meet our long-term needs.  To this end, we have awarded one contract for seven drilling rigs to be built in the Atlântico Sul shipyard in Pernambuco State.  These rigs will be owned by Sete Brasil S.A. (Sete BR), a Brazilian company in which we hold a 10% interest.  We expect to fulfill our future drilling requirements with a combination of rigs built in Brazil, supplemented when needed by the international fleet of deepwater rigs.

37

For our shallow water segment, we are building and will operate two jack-up drilling units designed to operate in water depths of up to 107 meters (350 feet) with High Pressure High Temperature (HPHT) capabilities.  We expect to begin operating these units in 2012.

We announced in November 2010 that we had signed two contracts worth a total of U.S.$3.46 billion for the construction of eight hulls for FPSOs to be used in the pre-salt area of the Santos Basin.  The FPSOs will be built in the State of Rio Grande do Sul.  These units are part of the new strategy for the construction of production units that emphasizes project simplification and the use of standardized equipment.  By producing identical hulls in series we expect to accelerate construction, gain economies of scale and minimize costs.

We are also increasing our use of industry standard equipment instead of developing our own customized equipment.  We intend to minimize costs by increasing supervision over suppliers and dividing engineering procurement and construction packages into smaller pieces.

We are an integrated company with a dominant market share in our home market.  We own and operate 12 refineries in Brazil, with a total net distillation capacity of 2,007 mbbl/d, and are one of the world’s largest refiners.  As of December 31, 2010, we operated 90% of Brazil’s total refining capacity.  We supplied almost all of the refined product needs of third-party wholesalers, exporters and petrochemical companies, in addition to the needs of our Distribution segment.  We operate a large and complex infrastructure of pipelines and terminals and a shipping fleet to transport oil products and crude oil to domestic and export markets.  Most of our refineries are located near our crude oil pipelines, storage facilities, refined product pipelines and major petrochemical facilities, facilitating access to crude oil supplies and end-users.

We also import and export crude oil and oil products.  We import certain oil products, particularly diesel, for which Brazilian demand exceeds refining capacity.  We expect the need for imports to decline in the future as we build additional refining capacity and upgrade our refineries to facilitate the processing of domestically produced crudes. 

Our Refining, Transportation and Marketing segment also includes petrochemical operations that add value to the hydrocarbons we produce and meet the needs of the growing Brazilian economy. 

38

We participate in refining, transportation and marketing operations outside of Brazil through our International business segment.  See “—International.”

Refining

Our refining capacity in Brazil as of December 31, 2010, was 2,007 mbbl/d and our average throughput during 2010 was 1,798 mbbl/d.

In recent years, we have made substantial investments in our refinery system for the following purposes:

•Improve gasoline and diesel quality to comply with stricter environmental regulations;

•Increase crude slate flexibility to process more Brazilian crude, taking advantage of light/heavy crude price differentials; and

•Reduce the environmental impact of our refining operations.

In 2010, we invested a total of U.S.$6,681 million in our refineries, of which U.S.$5,342 million was invested for hydrotreating units to improve the quality of our diesel and gasoline, U.S.$1,203 million for coking units to convert heavy oil into lighter products, and U.S.$136 million for debottlenecking projects.

During 2011, we expect to complete the following investment projects at our refineries:

•Diesel quality upgrades at RECAP and RLAM; and

•Gasoline quality upgrades at REFAP, RPBC, REDUC, REGAP, REVAP, RLAM and RECAP.

The following refinery upgrades are underway for expected completion between 2012 and 2014:

•Diesel quality upgrades at REGAP, REPAR, REPLAN and RPBC;

39

•Gasoline quality upgrades at REPAR; and

•Delayed coking units at Abreu e Lima Refinery, Comperj, Premium Refinery – 1^st Phase and REPAR.

The following refinery upgrade projects are scheduled for completion after 2014:

•Diesel quality upgrades at REDUC; and

•Mild thermal cracking units to improve diesel and gasoline quality at REMAN.

By the end of 2013, we will reduce the maximum sulfur content of the diesel produced in our refineries from 1800 ppm to 500 ppm, and six of our refineries will be producing 50 ppm sulfur diesel.  By the beginning of 2014, we will reduce the maximum sulfur content of the gasoline produced in our refineries from 1,000 ppm to 50 ppm.

Major Refinery Projects

Brazil has one of the world’s most dynamic economies with above average rates of demand growth for automotive fuels.  We are planning capacity expansions to meet the needs of this growing market and add value to our growing volumes of crude oil production in Brazil.  We are currently building two new refining facilities:

•Complexo Petroquímico do Rio de Janeiro—Comperj, an integrated refining and petrochemical complex.  We broke ground in 2008, and began construction in 2010.  The 165 mbbl/d refining operation is scheduled to start up in 2013.  A second phase, scheduled for 2018, will increase capacity to 330 mbbl/d and add petrochemicals manufacturing.  

•Abreu e Lima, a refinery in Northeastern Brazil in a proposed partnership with Petróleos de Venezuela S.A. (PDVSA), the Venezuelan state oil company.  This refinery is designed to process 230 mbbl/d of crude oil to produce 162 mbbl/d of low sulfur diesel (10 ppm) as well as LPG, naphtha, bunker fuel and petroleum coke.  We expect operations to come on stream in 2013.

We are in the planning stage for two new refineries in Northeastern Brazil.  Both refineries will be designed to process 20° API heavy crude oil, maximize production of low sulfur diesel, and also produce LPG, naphtha, low sulfur kerosene, bunker fuel and petroleum coke.  Both will be integrated with marine storage terminals.

•Premium I in the State of Maranhão will be built in two phases of 300 mbbl/d each.

•Premium II in the State of Ceará will have processing capacity of 300 mbbl/d.

Delivery Commitments

We sell crude oil under a variety of contractual obligations, primarily through long-term and spot-market contracts.  Our spot-market contracts specify the delivery of fixed and determinable quantities, subject to a price negotiation with third parties on a delivery-by-delivery basis. We are contractually committed under one long-term supply contract to deliver a total of approximately 300 mbbl/d in 2011, 200 mbbl/d in 2012 and 200 mbbl/d in 2013 of crude oil. We have met all contractual delivery commitments, and we believe our domestic proved reserves are sufficient to allow us to continue to deliver all contracted volumes.  We expect our contractual delivery obligations to increase over the next nine years as we increase our crude oil production.  For 2011, approximately 55% of our exported domestic crude oil production will be committed to meeting our contractual delivery commitments to third parties.

Imports and Exports

We use exports and imports of crude oil and oil products to balance our domestic production and refinery capacity with market needs and optimize our refining margins.  Much of the crude oil we produce in Brazil is heavy or intermediate, and we import some light crude to balance the slate for our refineries, which were originally designed to run on lighter imported crude, and export heavier crude that is surplus to our needs. 

41

We import diesel, for which there is insufficient production capacity in our Brazilian refineries.  We export fuel oil, of which 65 mbbl/d was exported as bunker fuel.  Our imports and exports of other products, such as gasoline, depend on demand levels and relative pricing in the Brazilian market.  The table below shows our exports and imports of crude oil and oil products in 2010, 2009 and 2008:

Logistics and Infrastructure

We own and operate an extensive network of crude oil and oil products pipelines in Brazil that connect our terminals, refineries and other primary distribution points.  On December 31, 2010, our onshore and offshore, crude oil and oil products pipelines extended 15,199 km (9,397 miles).  We operate 28 marine storage terminals and 20 other tank farms with nominal aggregate storage capacity of 63 million barrels.  Our marine terminals handle an average 10,422 tankers annually.  We are working in partnership with other companies to develop and expand Brazil’s ethanol pipeline and logistics network.

Until 1998, we held the monopoly on oil and natural gas pipelines in Brazil and shipping oil products to and from Brazil.  The deregulation of the Brazilian oil sector in that year provided for open competition in the construction and operation of pipeline facilities and gave the ANP the power to authorize entities other than Petrobras to transport crude oil, natural gas and oil products.  In accordance with this deregulation, we transferred our transportation and storage network and fleet to a separate wholly owned subsidiary, Petrobras Transporte S.A.—Transpetro, to allow third parties to access our excess capacity on a non-discriminatory basis.  We enjoy preferred access to the Transpetro network based on our historical usage levels and, in practice, third parties make very limited use of this network.

We operate a fleet of owned and chartered vessels.  These provide shuttle services between our producing basins offshore Brazil and the Brazilian mainland, and shipping to other parts of South America and internationally.  The fleet includes double-hulled vessels, which operate internationally where required by law, and single-hulled vessels, which operate in South America and Africa only.  We are increasing our fleet of owned vessels to replace older vessels, decrease our dependency on chartered vessels and exposure to charter rates tied to the U.S. dollar, and accommodate growing production volumes.  Upgrades will include replacing single-hulled tankers with double-hulled vessels and replacing vessels nearing the end of their 25-year useful life.  Our long-term strategy continues to focus on the flexibility afforded by operating a combination of owned and chartered vessels.

We plan to take delivery of 49 new vessels by 2015, all to be built in Brazilian shipyards.  We have ongoing contracts with five shipyards for delivery of 41 large oil tankers, bunkering vessels and LPG carriers between 2011 and 2015.  We expect to contract an additional eight product tankers in 2011.

Petrochemicals

Our petrochemicals operations provide a growing market for the crude oil and other hydrocarbons we produce, increase our value added and provide domestic sources for products that would otherwise be imported.  Our strategy is to increase domestic production of basic petrochemicals and engage in second generation and biopolymer activities through investments in companies in Brazil and abroad, capturing synergies within all our businesses. 

In the past, the Brazilian petrochemicals industry was fragmented with a large number of small companies, many of which were not internationally competitive and were therefore poor customers for our petrochemical feedstocks.  In a series of mergers and a capital subscription completed in 2010, we have participated in consolidating and restructuring the Brazilian petrochemicals industry by creating Brazil’s largest petrochemicals company and one of the largest producers of thermoplastic resin in the Americas, Braskem S.A. (Braskem).  Braskem is a publically traded company in which we hold a 36.1% interest.  The controlling shareholder, with 38.3%, is Odebrecht S.A. (Odebrecht).  Braskem operates 31 petrochemical plants, produces basic petrochemical and plastics, and conducts related distribution and waste processing operations.

The table below sets forth the primary production capacities of Braskem as of December 31, 2010:

Braskem: Nominal Capacity by Petrochemical Type

Braskem
Ethylene	3.77
Propylene	1.59
Polyethylene	3.06
Polypropylene	2.88

Cumene	0.32

On April 1, 2011, we announced the acquisition of Innova S.A. from Petrobras Energia International S.A., a wholly owned subsidiary of Petrobras Argentina S.A., for U.S.$332 million.  Innova S.A. is located in the Petrochemical Complex of Triunfo in the State of Rio Grande do Sul in Southern Brazil.  The acquisition will allow us to further our goals related to the development of the Brazilian petrochemicals sector while permitting Petrobras Argentina S.A. to concentrate on activities in Argentina.

43

We have three new petrochemcials projects under construction or in various stages of engineering or design:

•Complexo Petroquímico do Rio de Janeiro—Comperj: we have plans to develop a petrochemicals complex to be integrated with the Comperj refinery to produce materials for the plastics industry;

•PetroquímicaSuape Complex in Pernambuco:  to produce purified terephthalic acid (PTA), polyethylene terephthalate (PET) resin, and polymer and polyester filament textiles; and

•Companhia de Coque Calcinado de Petróleo—Coquepar:  calcined petroleum coke plants in Rio de Janeiro and Paraná.

We are Brazil’s leading oil products distributor, operating through our own retail network, through our own wholesale channels, and by supplying other fuel wholesalers and retailers.  Our Distribution segment sells oil products that are primarily produced by our Refining, Transportation and Marketing segment (RTM), and works to expand the domestic market for these oil products and for other fuels, including LPG, ethanol and biodiesel. 

The primary focus of our Distribution segment is to:

•Lead the market in the domestic distribution of oil products and biofuels, increasing our market share and profitability through an integrated supply chain; and

•Become the preferred brand of our consumers while upholding and promoting social and environmental responsibility.

We supply and operate Petrobras Distribuidora S.A.—BR, which accounts for 38.8% of the total Brazilian retail and wholesale distribution market.  BR distributes oil products, ethanol and biodiesel, and vehicular natural gas to retail, commercial and industrial customers.  In 2010, BR sold the equivalent of 797.5 mbbl/d of oil products and other fuels to wholesale and retail customers, of which the largest portion (44.4%) was diesel.

At December 31, 2010, our BR branded service station network was Brazil’s leading retail marketer, with 7,306 service stations, or 19.2% of the stations in Brazil.  BR-owned and franchised stations make up 30.9% of Brazil’s retail sales of diesel, gasoline, ethanol, vehicular natural gas and lubricants. 

Most BR stations are owned by franchisees that use the BR brand name under license and purchase exclusively from us; we also provide franchisees with technical support, training and advertising.  We own 767 of the BR stations and are required by law to subcontract the operation of these owned stations to third parties.  We believe that our market share position is supported by a strong BR brand image and by the remodeling of service stations and addition of lubrication centers and convenience stores.  

44

 Our wholesale distribution of oil products and biofuels under the BR brand to commercial and industrial customers accounts for 56.1% of the total Brazilian wholesale market.  Our customers include aviation, transportation and industrial companies, as well as utilities and government entities.

We also sell oil products produced by RTM to other retailers and to wholesalers.

Our LPG distribution business, Liquigas Distribuidora, held a 22.3% market share and ranked second in LPG sales in Brazil in 2010, according to the ANP. 

Oil products sales in Brazil increased 9.0% in 2010 compared to 2009.  This increase was due mainly to Brazil’s economic growth and its corresponding growth in household income and consumer credit.

We participate in the retail sector in other South American countries through our International business segment.  See “—International.”

For more than two decades, we have been working actively to develop simultaneously Brazil’s natural gas reserves, production, infrastructure and markets.  As a result of our efforts, natural gas in 2009 supplied 8.7% of Brazil’s total energy needs, compared to 3.7% in 1998, and is projected to supply 14.2% of Brazil’s total energy needs by 2020, according to Empresa de Pesquisa Energética, a branch of the MME.

In 2010, our Exploration and Production operations produced 63.3 mmm³/d (2,235.44 mmcf/d) of natural gas.  The development plans for these operations are expected to result in substantial increases in gas production from the Espírito Santo and Santos Basins off the Brazilian coast, including from pre-salt reservoirs.  We expect domestic gas production to play an increasingly important role in the supply mix, but we will continue to import gas from Bolivia and use LNG imports selectively to provide supplemental supplies, particularly to meet surges in demand from the power sector. 

Our Gas and Power segment is responsible for monetizing and delivering the gas produced by our Exploration and Production segment, and gas purchased from other sources, including imported LNG.  The segment comprises gas transmission and distribution, LNG regasification, the manufacture of nitrogen-based fertilizers, gas-fired power generation, and power generation from renewable sources, including solar, wind and small-scale hydroelectric.

The primary focus on our Gas and Power segment is to:

•Add value by monetizing Petrobras’ associated and non-associated natural gas resources;

•Assure flexibility and reliability in the commercialization of natural gas;

•Expand the use of LNG to meet Brazilian gas demand and diversify our supply of natural gas;

•Optimize our thermoelectric power plant portfolio and supplement it with power generation from renewables; and

45

•Create an additional flexible means of monetizing our natural gas resources by investing in capacity to manufacture nitrogen fertilizers.     

Natural Gas

Following a multi-year infrastructure development program, including investments of approximately U.S.$13.33 billion (R$26.98 billion) in the last five years, we have built an integrated system centered around two main, interlinked, pipeline networks that allows us to deliver natural gas from our main offshore natural gas producing fields in the Campos and Espírito Santo Basins, as well as from two LNG terminals and a gas pipeline connection with Bolivia.

Our natural gas pipelines span 9,239 km (5,741.2 miles), including:

•Malha Sudeste (Southeast Network) (2,273.7 km/1,412.8 miles) serving Brazil’s most industrialized region, including Rio de Janeiro and São Paulo;

•Malha Nordeste (Northeast Network) (2,183.4 km/1,356.7 miles);

•Gasene (Southeast Northeast Interconnection Gas Pipeline) (1,387 km/861.8 miles);

•A 2,593 km (1,611.2 miles) Brazilian portion of the Bolivia-Brazil natural gas pipeline in Southeastern Brazil; and

•Urucu-Coari-Manaus pipeline (802.5 km/498.7 miles) and branches, connecting the Solimões Basin to Manaus and other northern cities.

In 2010, we invested U.S.$3.41 billion in our pipeline network, completed the Gasene interconnector, and extended our total network by 1,696 km (1,054 miles) as compared to 2009.   The following pipelines commenced operations in 2010:

Natural Gas Pipelines Starting Operations in 2010
Name	Route	Length (km/miles)	Capacity
Gascac	Cacimbas-Catu (completes Gasene)	954 km (593 miles)	up to 20 mmm³/d (706.3 mmcf/d)

GASCAV-UTG Sul Capixaba	Cabiúnas - UTG	10 km (6.2 mile)	2 mmm³/d (70.63 mmcf/d)

In 2011, we plan to invest a further U.S.$1.5 billion for incremental additions to our gas transportation system.

46

The map below shows our existing pipelines and our pipelines under construction.

We own and operate two LNG terminals, one in Rio de Janeiro with a send-out capacity of 20 mmm³/d (706 mmcf/d), and the other in Pecém (Ceará) in Northeastern Brazil with a send-out capacity of 7 mmm³/d (247 mmcf/d).  The terminals are supported by two LNG regasification vessels with capacities of 14 mmm³/d (494 mmcf/d) and 7 mmm³/d (247 mmcf/d).  These terminals and regasification ships give us the flexibility to import gas to supplement domestic natural gas supplies.  In 2010, we purchased 41 LNG cargoes, of which 36 were imported into Brazil and 5 were sold in international markets.  In addition, we plan to build a third LNG terminal in the State of Bahia, the construction of which will begin in 2012 and which we expect to be completed in 2013. 

We hold interests ranging from 24% to 100% in 20 of Brazil’s 27 local gas distribution companies.  In Espírito Santo State we hold exclusive rights to distribute natural gas through our BR subsidiary.  We estimate that we had a 23% net equity interest in the combined 49.0 mmm³/d (1,730 mmcf/d) of natural gas distributed by Brazil’s local distribution companies in 2010.

47

According to our estimates, our two most significant holdings, CEG Rio and Bahiagás, are Brazil’s third and fourth largest gas distributors. These companies, together with independent distributors Comgás and CEG supply 64% of the Brazilian market.

(1)                  Includes sales to local gas distribution companies in which we have an equity interest.

(2)                  Includes gas used in the transport system.

(3)                  Excludes internal consumption.

Natural gas consumption in Brazil by industrial, commercial and retail customers increased 15% in 2010 compared to 2009.  This increase was due mainly to Brazil’s economic growth and more competitive pricing of natural gas sold through short-term auctions.  Natural gas consumption in the power generation industry increased 198% from 2009 to 2010 due to reduced rainfall and higher industrial output.  Natural gas consumption by refineries and fertilizer plants increased 20%.

Long-Term Natural Gas Commitments

When we began investment in the Bolivia-Brazil pipeline in 1996, we entered into long-term contracts with three companies:

•Gas Supply Agreement (GSA) with the Bolivian state-owned company Yacimientos Petrolíferos Fiscales Bolivianos (YPFB), to purchase certain minimum volumes of natural gas at prices linked to the international fuel oil price through 2019, after which the agreement may be extended until all contracted volume has been delivered.  On December 18, 2009, Petrobras and YPFB signed the fourth amendment to the GSA, which provides for additional payments to YPFB for liquids contained in the natural gas purchased by Petrobras through the GSA, of between U.S.$100 million and U.S.$180 million per year, retroactive to May 2007.  As of February 2010, Petrobras has paid all obligations owed for 2007.  Additional payments for subsequent years will be paid after YPFB fulfills conditions precedent established in the amendment;

•Ship-or-Pay agreement with Gás Transboliviano (GTB), owner and operator of the Bolivian portion of the pipeline to transport certain minimum volumes of natural gas through 2019; and

48

•Ship-or-Pay agreement with Transportadora Brasileira Gasoduto Bolivia-Brasil (TBG), owner and operator of the Brazilian portion of the pipeline to transport certain minimum volumes of natural gas through 2019.

Our volume obligations under the ship-or-pay arrangements were generally designed to match our gas purchase obligations under the GSA.  The tables below show our contractual commitments under these agreements for the five-year period from 2011 through 2015.

(5)           Amounts calculated based on current prices defined in natural gas transport contracts.

Gas Sales Contracts

In recent years, we have introduced a variety of supply contracts designed to create flexibility in matching customer demand with our gas supply capabilities.  These include flexible, interruptible and preferential gas supply contracts as well as auction mechanisms for short-term contracts.  In 2010, we introduced weekly electronic auctions offering short-term natural gas volumes that had been reserved for gas-fired power plants, but were not dispatched.

49

The table below shows our future gas supply commitments from 2011 to 2015, including sales to both local gas distribution companies and gas-fired power plants.

Short-Term Natural Gas Commitments

In 2009, we contributed to the development of a short-term market for natural gas sales, focusing on the industrial market as an alternative to the market for power generation when the power plants are not being dispatched.  Sales under these short-term contracts were accomplished by an electronic auction system conducted by means of the Internet.  These auctions commercialized natural gas volumes reserved for but not otherwise utilized by local gas distributors, and allowed us to offer end users more competitive prices.  On average, 4.4 mmm³/d of natural gas were sold under these short-term contracts in 2009, with volumes reaching 7.8 mmm³/d in 2010.  The last auction resulted in a sales record of 9.4 mmm³/d for a four-month delivery period.

In April 2010, we implemented a new method for selling short-term natural gas.  On a weekly basis, we offer for sale to the non-thermoelectric market volumes of natural gas that had been originally reserved for gas-fired power plants but that were not dispatched.  Under this method, weekly sales begin with orders from gas distribution companies for deliveries to be made within the subsequent four-week period.  Depending on the availability and cost of natural gas during that period, we have the option of either accepting or rejecting the orders.  This new method allowed us to sell an average of 300,000 m³/d of natural gas, with a sales record of 1.6 mmm³/d in May 2010.

Fertilizers

We are expanding production of nitrogenous fertilizers in order to meet the growing needs of Brazilian agriculture, to substitute for imports, and to expand the market for natural gas.  Effective January 1, 2010, we transferred our fertilizer business from the Refining, Transportation and Marketing segment to the Gas and Power segment in order to better exploit business synergies.

Our fertilizer plants in Bahia and Sergipe produce ammonia and urea for the Brazilian market.  In 2010, these plants sold a combined 235,739 t of ammonia and 772,059 t of urea.  We are currently building a facility with the capacity to produce 200,000 m³/year of ARLA 32, an aqueous 32.5% urea solution.  We are also conducting feasibility studies for up to four additional fertilizer facilities.

Power

To further our goal of developing natural gas demand in Brazil, we have invested in power plants and the associated system of gas supply contracts.  These plants are designed to supplement power from the hydroelectric stations that supply an average of 90% of the country’s electric power needs in a given year.  Gas-fired power is particularly needed during times of peak demand, high economic growth, and drought.

50

We own interests in 25 thermoelectric power plants with a combined installed capacity at year-end 2010 of 5,771 MW, equivalent to 64% of Brazil’s total thermoelectric capacity.  Of this total, 5,372 MW was in thermoelectric plants controlled by us and 99% (5,340 MW) was gas-fired.  Under Brazil’s power pricing regime, we may sell only power-generating capacity that is certified by the MME.  At year-end 2010, due to gas supply constraints, the MME certified 3,619 MWavg of commercial capacity, or 67% of the installed capacity controlled by us. 

In 2010, the Brazilian hydroelectric system generated 48,270 MWavg of electricity, or 89% of the country’s needs.  The Sistema Interligado Nacional—SIN (National Interconnected Power System), was called upon to supplement this power with an average 5,943 MW, of which we generated an average 1,837 MW of electricity in 2010, compared to 525 MW in 2009. 

We also export energy to neighboring countries.  In 2010, we exported 110.2 MWavg to Argentina and Uruguay.

Commitments for Future Generation Capacity and Electricity Sales

Under a 2007 agreement with the ANEEL, we are committed to increasing our ability to supply power to the grid by increasing natural gas supplies, including LNG, converting some existing power plants to dual-fuel operation and leasing backup oil-fired power plants.  By 2011 we are committed to supply up to 5,609 MW of installed capacity and expect to have an average 3,669 MW certified capacity available for sale, exclusive of our own power requirements.

The table below shows the installed capacity and commercial capacity of the thermoelectric power plants controlled by us for 2010 through 2013 under our agreement with the ANEEL: 

Installed Power Capacity and Utilization
	2010	2011	2012(2)	2013
Gross installed capacity (MW)	5,372	5,609	5,205	5,205
Certified commercial capacity(1) (MWavg)	3,619	3,669	3,353	3,462

(1)                  Weighted average of certified commercial capacity for the year.

(2)                  Our installed and commercial capacity will be reduced in 2012 due to the termination of our lease of the Araucaria thermoelectric power plant.

In 2010, we invested U.S.$358.2 million (R$630.8 million) in thermoelectric generation.

We sell our power output under long-term contracts for “standby availability” and long-term bilateral contracts, primarily with power distribution companies.  Of the total 3,579 MWavg of power available for sale in 2012 (including the certified commercial capacity of our plants and 226 MWavg of power purchased from third parties), approximately 45% has already been sold as standby availability in the 2005 and 2006 auctions, and approximately 55% has been committed under bilateral contracts.  We also have the option to fulfill our contractual commitments by purchasing power from third parties.

The following table summarizes our commitments under standby availability and bilateral contracts, power purchased from third parties, and the power we expect to be available for sale.

(2)      Represents the remaining commercial capacity available for sale beginning in 2011.

51

In the 2005 and 2006 auctions, we sold standby availability of 1,391 and 205 MWavg, respectively, on 15-year contracts beginning in 2008 to 2011. Under the terms of these contracts, we will be compensated a fixed amount whether or not we generate any power, and we receive an additional amount for the energy we actually generate at a price that is set on the date of the auction and revised annually based on an inflation-adjusted fuel oil basket. This represented most of our capacity that is eligible to be sold through the auction system.  We have been compensated for the standby availability from the 2005 and 2006 auctions since 2008, with the capacity compensation stepping up through 2011, at which time it stabilizes. These contracts generate losses when our actual costs of generating power increase and our prices do not rise accordingly.

Our future commitments under bilateral contracts are 2,275 MWavg in 2011, 1,983 MWavg in 2012 and 2,066 MWavg in 2013.  The agreements will run off gradually, with the last contract expiring in 2028.  As existing bilateral contracts run-off, we will sell our remaining certified power-generation capacity under short- and medium-term bilateral contracts and auctions conducted by us and by the MME.

Renewable Energy

We have invested, alone and in partnership with other companies, in renewable power generation sources in Brazil including wind and small hydroelectric plants.  Our net interests are equivalent to 316.5 MW of hydroelectric capacity and 105.8 MW of wind capacity.  We and our partners sell energy from these plants directly to the Brazilian federal government via “reserve energy” auctions.

We have operations in more than 20 countries outside Brazil, encompassing all phases of the energy business.  The primary focus of our international operations is to:

•Use our technical expertise in deepwater exploration and production to participate in high-potential and frontier offshore regions; and

•Integrate international downstream operations aligned with our domestic activities.

International Upstream Activities

Most of our international activities are in exploration and production of oil and gas.  We have long been active in Latin America.  In the Gulf of Mexico and West Africa, we focus on opportunities to leverage the deepwater expertise we have developed in Brazil.  We have preliminary exploratory efforts underway in other regions.

In 2010, our net production outside Brazil averaged 146 mbbl/d of crude oil and NGLs and 16 mmm³/d (566 mmcf/d) of natural gas, representing 10% of our total production on a barrels of oil equivalent basis.

(1)                  Most of  the Argentine exploration and production projects are held through our indirect 67.2% share in PESA.

(2)                  Production-sharing contract, under which Petrobras’ expenditures are reimbursed only if exploration results in economically viable oil discoveries.

(3)                  Joint venture through PESA.

(4)                  Non-risk service contract, under which Petrobras’ expenditures are reimbursed regardless of whether exploration results in economically  viable oil discoveries.

During 2010, our capital expenditures for international exploration and production totaled U.S.$1.9 billion, representing 8.3% of our total exploration and production capital spending.

South America

We are present in Argentina, Bolivia, Colombia, Ecuador, Peru, Venezuela and Uruguay.  In 2010, our average net production from South America (outside of Brazil) was 180.6 mboe/d, or 75% of our international production.  Reserves in the region represent 75% of our international reserves.  Our most significant natural gas production operations outside of Brazil are located in Argentina and Bolivia, where we produced an average 15.2 mmm³/d (536.8 mmcfd/d) of natural gas in 2010, or 95% of our international production.  Argentina and Bolivia together accounted for 35% of our worldwide production of natural gas in 2010.

Our largest operating region outside Brazil is Argentina, where we operate primarily through our 67.2% interest in Petrobras Energia S.A. (PESA).  Our main oil production is concentrated in the Medanito, El Tordillo and Puesto Hernández fields, and our main gas production is concentrated in the Santa Cruz and Sierra Chata fields in the province of Neuquén.  We also hold direct and indirect interests of 52.6% in Petrolera Entre Lomas S.A. (PELSA), whose main oil production is in Entre Lomas.

In Bolivia, our production comes principally from the San Alberto and San Antonio fields.  Following enactment of the Bolivian government’s May 1, 2006 nationalization of hydrocarbons, we entered into new production-sharing contracts under which we continue to operate the fields, but are required to make all hydrocarbon sales through YPFB with the right to recover our costs and participate in profits.  On January 25, 2009, Bolivia adopted a new constitution that prohibits private ownership of the country’s oil and gas resources.  As a result, we were not able to include any of our Bolivian proved reserves in our proved reserves for year-end 2010.  We continue to report production from our operations in Bolivia under our existing contracts in that country.  In January 2011, the Bolivian government approved the agreement between Petrobras Bolivia S.A. and Total E&P Bolivie S.A., according to which we have acquired a 30% interest in the Itaú gas field and assumed control of the field’s operations.

In Colombia, in January 2010, we negotiated a farm-out agreement in the Balay Block, where we hold a 45% interest, for 15% of our interest to Petroamerica Oil Corporation and 10% of our interest to Sorgenia E&P Colombia B.V. In March 2010, we announced discoveries in the Balay Block, where ongoing tests confirmed the presence of oil at approximately 28° API.  Our portfolio also includes other onshore exploration and production contracts.

54

We are present in Venezuela  through four joint ventures with subsidiaries of Petróleos de Venezuela S.A. (PDVSA), which hold exploration and production rights and in which we hold minority interests.  PDVSA is the majority holder and operator.

In Peru, we announced discoveries of natural gas in Lote 58, located in the Department of Cuzco, which are undergoing commercial evaluations.  We are the sole operator of Lote 58.  Our main assets in the country are exploration and production rights in Block 10 in Northern Peru. In 2010, the volumes booked by the Kinteroni Gas Project, in Lote 57, accounted for a 65.1 mmboe increase of the company’s reserves in the country.

In 2010, we chose to discontinue operations in Ecuador following changes in that country’s laws and regulations.

North America

In the United States we focus on deepwater fields in the Gulf of Mexico.  As of December 31, 2010, we held interests in 189 offshore blocks, 125 of which we operate.  In January 2010, we acquired the remaining 50% interest in the Cascade field.  In 2011, we expect to begin production in the Cascade and Chinook fields, where we will implement new technologies and become the first Gulf of Mexico operation to use a FPSO. 

Our exploration activities in the United States were reduced in 2010 due to the moratorium imposed by the United States government after the Gulf oil spill.

We have held non-risk service contracts for the Cuervito and Fronterizo Blocks in the Burgos Basin of Mexico  since 2003.  Under these service contracts, we receive fees for our services, but any producing wells and production are transferred to the Mexican national oil company Petróleos Mexicanos (Pemex).  We also have agreements to share deepwater expertise with Pemex.

Europe

Under a joint study agreement with Petrogal (Galp) and Partex, we are acquiring and analyzing seismic data related to the Peniche Basin offshore Portugal.   

Africa

In Angola, we have announced deepwater discoveries in Block 15, in which we have a 5% interest.  In 2010, we produced a net 1.9 mboe/d from Block 2, which we do not operate.

In Nigeria, our net production is 54.6 mboe/d from the Agbami and Akpo fields, and we enhanced production at those fields in 2010.  The Egina field is in its development stage, while the Preowei and Egina South fields are under appraisal.

In Namibia, we continue to evaluate the potential of Block 2714A before deciding whether to drill an exploratory well.   This block is located in offshore Southern Namibia and covers an area of approximately 5,500 km² (1.4 million acres) in water depths from 150 to 1,500 meters (492 to 4,921 feet).

In Tanzania, we continue exploratory studies of the offshore deepwater blocks 5 and 6 in partnership with TPDC.  Each block encompasses approximately 11,000 km² (2.7 million acres).  In 2010, we carried out two 3D seismic surveys that covered a total of 2,700 km² (0.7 million acres) of the area.

Asia and Oceania

In April 2010, we acquired a 50% interest in an exploratory block in the North Carnarvon Basin in Australia  and committed to drill the first exploration well. We have made no discoveries of natural gas in our Artemis-1 well.

In New Zealand, we obtained permission, through public bidding, to operate exploration offshore Block 52707, in the Raukumara Basin. We have a 100% interest and plan to undertake seismic studies and drill one exploration well.

Other International Activities

Our other international activities, including refining, petrochemicals, distribution and gas and power activities, are described below.

South America

We have integrated operations in South America, particularly in Argentina, where we participate across the energy value chain.  Through our interest in PESA, we own two refineries providing 81 mbbl/d of net capacity, an interest in the Refinor/Campo Duran Refinery, and three petrochemical plants (two in Argentina and one in Brazil).  We directly own 604 retail service stations operating under the Petrobras brand name.  We also own the Pichi Picún Leufú hydroelectric plant, the Genelba gas-fired thermoelectric plant, an interest in natural gas transportation company TGS (Transportadora Gas del Sur), and interests in energy marketer Edesur, and Mega Company, a natural gas separation facility. 

In 2010, PESA agreed to sell its fertilizer business for U.S.$88 million.  In 2010, PESA also agreed to sell its refinery in San Lorenzo and about 360 points of sale for approximately U.S.$110 million. This transfer was consummated on May 2, 2011, although it remains subject to approval by the Argentine competition authority.

In Bolivia, we operate gas fields that supply gas to Brazil.  We hold an 11% interest in GTB, owner of the Bolivian section of the Bolivia-to-Brazil (BTB) pipeline that transports natural gas we produce in Bolivia to the Brazilian market.  We also hold a 44.5% interest in Transierra S.A., which owns the Yacuiba-Rio Grande gas pipeline (Gasyrg) linking the San Alberto and San Antonio fields to the BTB pipeline.

In Chile, our assets comprise 229 service stations, 11 airport terminals and a lubricant plant.  

In Colombia, our assets comprise 86 service stations and a lubricant plant.  

In Paraguay, our assets comprise 165 service stations, 1 aviation fueling installation and 1 LPG refueling plant.  

In Uruguay, we have fuel distribution operations, with 87 service stations.  We also market marine products, asphalt and aviation products and distribution.

                The portfolio of our Gas and Power segment includes two gas distribution companies in Uruguay, Distribuidora de Gas Montevideo S.A (retail sales in Montevideo) and Conecta S.A. (national commercial sales).  See “—Gas and Power”

North America

In the United States we own 100% of the Pasadena Refining System (PRSI) and 100% of PRSI’s related trading company (PRSI Trading Company). On December 20, 2010, the 129th District Court of Harris County, Texas issued a ruling confirming an arbitration award issued on April 10, 2009, which found that Petrobras America, Inc. (PAI), our indirect subsidiary in the United States, and its affiliates had effectively acquired the remaining shares that led PAI to hold 100% of the interest held by our former partner Astra Oil Trading NV (Astra) and its affiliates in both PRSI and PRSI Trading Company, and set the put-option exercise price for PRSI and PRSI Trading Company at U.S.$296 million and U.S.$170 million, respectively. PAI does not object to the confirmation of the put option exercised by Astra and its affiliates or PAI’s ownership of 100% of PRSI and 100% of PRSI Trading Company.  However, PAI is appealing the December 20, 2010 ruling in order to challenge certain other aspects related to the implementation of the arbitral award.  Enforcement of the judgment is suspended pending appeal. There are other ongoing judicial proceedings related to indemnifications among the parties involved.

Biofuels

Since 2009, our Biofuels operations have been part of the Corporate segment.  They were previously included in the Gas and Power segment.  Brazil is a global leader in the use of ethanol as fuel for light vehicles.  Today, 90.83% of new light vehicles sold in Brazil have flexfuel capability, and service stations offer a choice of 100% ethanol and an ethanol/gasoline blend.   All diesel fuel sold in Brazil since January 2010 is required to be at least 5% biodiesel. 

We supply 10.8% of Brazil’s biodiesel and we act as a market catalyst by securing and blending biodiesel supplies and furnishing these to smaller distributors as well as our own service stations. Our biodiesel plants, located at Candeias and Quixada in Northeastern Brazil and at Montes Claros in Southeastern Brazil, purchase vegetable oils from small farmers and industrial producers.  After various operational improvements, the capacity of these three plants totals 7.5 mbbl/d.  During 2010, we began biodiesel production at our 50% owned Marialva plant, increasing our total capacity to 8.5 mbbl/d. In an effort to decrease our dependency on third-party sources of vegetable oils, we also invested in a vegetable oil extracting company near our Candeias plant as part of our strategy to vertically integrate our operations.

We participate in the growing ethanol industry through production, transportation, distribution, wholesale and exports, and by stimulating improvements in product quality.  In 2010, in order to strengthen our participation in the ethanol industry, we invested U.S.$387 million (R$682.5 million) to acquire a 26.5% interest in Guarani S.A., the third-largest sugarcane processor in Brazil, with plans to invest an additional U.S.$527 million (R$928.5 million) over five years to acquire an additional 19.2% interest, bringing our total interest in Guarani S.A. to 45.7%.  We also entered into a strategic partnership with Grupo São Martinho, with investments of U.S.$244 million (R$422 million), in order to operate and expand the production of the Usina Boa Vista and SMBJ Agroindustrial S.A. through our 49% interest in Nova Fronteira Bioenergia S.A. As a result of these partnerships and investments, our total annual milling capacity amounts to 24.5 mmt and our total ethanol production capacity amounts to 27.0 mbbl/d.  

In 2010, we exported 306,000 m³ of ethanol, 16.11% of Brazil’s total ethanol exports, including industrial ethanol to Asia and fuel ethanol to the United States and Europe.

Information on PifCo

PifCo was incorporated in order to facilitate and finance the import of crude oil and oil products by us into Brazil, and has been our wholly owned subsidiary since 2000.  Currently, PifCo acts as an intermediary between third-party oil suppliers and us by engaging in crude oil and oil product purchases from international suppliers, and reselling crude oil and oil products in U.S. dollars to us under terms that allow payment in up to approximately 30 days, without a premium. Prior to April 2010, we paid PifCo for shipments of crude oil and oil products on a deferred payment basis, at a price which included a premium to compensate PifCo for its financing costs.  PifCo also purchases crude oil and oil products from us for sale outside Brazil.  Additionally, PifCo sells and purchases crude oil and oil products to and from third parties and related parties, mainly outside Brazil.  PifCo is generally able to obtain credit to finance purchases on the same terms granted to us, and PifCo buys crude oil and oil products at the same price that suppliers would charge us directly.  PifCo is gradually reducing its sales of crude oil and oil products to us and will gradually reduce its sales of crude oil and oil products to third parties, and will eventually cease these commercial operations altogether. At that time, PifCo will become a finance subsidiary functioning as a vehicle for us to raise capital for our operations outside of Brazil through the issuance of debt securities in the international capital markets, among other means.

We have provided unconditional and irrevocable guaranties of payment for all of PifCo’s issuances of SEC-registered debt securities since February 2009.  On March 31, 2010, we issued six additional unconditional and irrevocable guaranties of payment to replace the standby purchase agreements that previously supported PifCo’s SEC-registered debt securities issued prior to February 2009.  As a result, we currently provide unconditional and irrevocable guaranties of payment for all of PifCo’s outstanding SEC-registered debt securities.

PifCo’s Corporate Structure

PifCo was established on September 24, 1997 as Brasoil Finance Company, a wholly owned subsidiary of Braspetro Oil Services Company, or Brasoil, a wholly owned subsidiary of Petrobras Internacional S.A. (Braspetro), which has since been absorbed by us.  PifCo’s voting shares were transferred from Brasoil to us in 2000, since which time it has been our wholly owned subsidiary.  Petrobras International Finance Company is an exempted company incorporated with limited liability under the laws of the Cayman Islands.  PifCo’s registered office is located at Harbour Place, 103 South Church Street, 4th floor, P.O. Box 1034GT, George Town, Grand Cayman, Cayman Islands, and PifCo’s telephone number is 55-21-3487-2375.

PifCo’s four subsidiaries are:

•Petrobras Europe Limited (PEL):   In May 2001, PifCo established PEL, a wholly owned subsidiary incorporated and based in the United Kingdom, to consolidate our trade activities in Europe, the Middle East, the Far East and Africa.  These activities consist of advising on, and negotiating the terms and conditions for, crude oil and oil products supplied to PifCo, PIB BV, and us, as well as marketing Brazilian crude oil and crude oil products exported to the geographic areas in which PEL operates.  PEL plays an advisory role in connection with these activities and undertakes no direct or additional commercial or financial risk.  PEL provides these advisory and marketing services as an independent contractor, pursuant to a services agreement between PEL and us.  In exchange, we compensate PEL for all costs incurred in connection with these activities, plus a margin.

•Petrobras Finance Limited (PFL):   In December 2001, PifCo established PFL, a wholly owned subsidiary incorporated and registered in the Cayman Islands.  PFL primarily purchases fuel oil from us and sells the products in the international market in order to generate export receivables to cover its obligations to transfer these receivables to a trust under an exports prepayment program.  Until June 1, 2006, PFL also purchased bunker fuel from us.  The exports prepayment program helps provide PFL with the funding necessary to purchase oil products from us, as described below.

58

•Bear Insurance Company Limited (BEAR):   In January 2003, BEAR was transferred to PifCo from Brasoil.  This transaction took place as part of the restructuring of our international business segment.  BEAR currently serves as our captive insurance company, advising on and negotiating the terms and conditions of, certain of our insurance policies and certain insurance and reinsurance policies of our subsidiaries.

•Petrobras Singapore Private Limited (PSPL):   In April 2006, PifCo created PSPL, a company incorporated in Singapore to trade oil and derivatives in connection with our trading activities in Asia.  This company initiated operations on July 1, 2006.

PifCo’s Principal Commercial Activities

PifCo purchases crude oil and oil products for resale to us and third parties.  PifCo acquires substantially all of its crude oil and oil products either through purchases on the spot market or short-term supply contracts.  PifCo also acquires a small portion of its crude oil and oil products through long-term supply contracts.  PifCo’s crude oil and oil product purchase obligations are, in most instances, guaranteed by us.  Prior to April 2010, PifCo resold the products purchased to us at the purchase price it paid, plus a premium, determined in accordance with a formula designed to pass on PifCo’s average costs of capital to us.  Currently, PifCo sells crude oil and oil products to us under terms that allow payment in up to approximately 30 days, without a premium.  PifCo also purchases crude oil and oil products from us for sale outside Brazil.  Additionally, PifCo sells and purchases crude oil and oil products to and from third parties and related parties, mainly outside Brazil. PifCo is gradually reducing its sales of crude oil and oil products to us and will gradually reduce its sales of crude oil and oil products to third parties, and will eventually cease these commercial operations altogether. At that time, PifCo will become a finance subsidiary functioning as a vehicle for us to raise capital for our operations outside of Brazil through the issuance of debt securities in the international capital markets, among other means.

In addition, PifCo finances its oil trading activities principally from commercial banks, including lines of credit, as well as through inter-company loans from us and the issuance of notes in the international capital markets.

Export Prepayment Program

In 2001, we created an export prepayment program to finance our fuel oil exports through the securitization of our fuel oil exports receivables.  A Cayman Islands trust, the PF Export Receivables Master Trust (Trust), raises funds by issuing certificates to investors and providing this funding to PFL to purchase fuel oil from us.  PFL purchases fuel oil from us under a Master Export Contract and a Prepayment Agreement, which establishes quarterly minimum purchase commitments.  PFL assigns all receivables from the sale of such exports to the Trust, and the receivables serve as collateral for the payment obligations due under the certificates.  The certificates represent senior undivided beneficial interests in the property of the Trust.

The value of receivables to be designated for sale in any quarterly period represents a portion, but not all, of the receivables expected to result from the sale of fuel oil by PFL in such period.  The balance of the receivables is the property of PFL.

Since the creation of the program, the Trust has issued a total of U.S.$1,500 million in Senior Trust Certificates.  We have prepaid or amortized a portion of the Senior Trust Certificates.  Currently, there are U.S.$264 million in Senior Certificates outstanding.

Property, Plant and Equipment

Petrobras

Our most important tangible assets are wells, platforms, refining facilities, pipelines, vessels and other transportation assets, and power plants.  Most of these are located in Brazil.  We own and lease our facilities and some owned facilities are subject to liens, although the value of encumbered assets is not material.

We have the right to exploit crude oil and gas reserves in Brazil under concession agreements, but the reserves themselves are the property of the government under Brazilian law. Item 4. “Information on the Company” includes a description of our reserves and sources of crude oil and natural gas, key tangible assets, and material plans to expand and improve our facilities.

PifCo

PifCo does not itself own or lease any material property, plant or equipment.

Regulation of the Oil and Gas Industry in Brazil  

Concession Regime for Oil and Gas

Under Brazilian law, the Brazilian federal government owns all crude oil and natural gas subsoil accumulations in Brazil.  The Brazilian federal government holds a monopoly over the exploration, production, refining and transportation of crude oil and oil products in Brazil and its continental shelf, with the exception that companies that were engaged in refining and distribution in 1953 were permitted to continue those activities.  Between 1953 and 1997, we were the Brazilian federal government’s exclusive agent for exploiting its monopoly, including the importation and exportation of crude oil and oil products.

As part of a comprehensive reform of the oil and gas regulatory system, the Brazilian Congress amended the Brazilian Constitution in 1995 to authorize the Brazilian federal government to contract with any state or privately-owned company to carry out upstream, oil refining, cross-border commercialization and transportation activities in Brazil of oil, natural gas and their respective products.  On August 6, 1997, Brazil enacted Law No. 9,478, which established a concession-based regulatory framework, ended our exclusive right to carry out oil and gas activities, and allowed competition in all aspects of the oil and gas industry in Brazil.  Since that time, we have been operating in an increasingly deregulated and competitive environment.  Law No. 9,478 also created an independent regulatory agency, the ANP, to regulate the oil, natural gas and renewable fuel industry in Brazil, and to create a competitive environment in the oil and gas sector.  Effective January 2, 2002, Brazil deregulated prices for crude oil, oil products and natural gas.

Law No. 9,478 established a concession-based regulatory framework and granted us the exclusive right to exploit crude oil reserves in each of our producing fields under concession contracts for an initial term of 27 years from the date when they were declared commercially profitable.  This initial 27-year period for production can be extended at the request of the concessionaire and subject to approval from the ANP.  Law No. 9,478 also established a procedural framework for us to claim exclusive exploratory rights for a period of up to three years, later extended to five years, to areas where we could demonstrate that we had made commercial discoveries or exploration investments prior to the enactment of the Law No. 9,478.  In order to perfect our claim to explore and develop these areas, we had to demonstrate that we had the financial capacity to carry out these activities, either alone or through other cooperative arrangements.

62

Taxation under Concession Regime for Oil and Gas

According to the Law No. 9,478 and under our concession agreements for exploration and production activities with ANP, we are required to pay the government the following:

•Signature bonuses paid upon the execution of the concession agreement, which are based on the amount of the winning bid, subject to the minimum signature bonuses published in the relevant bidding guidelines (edital de licitação);  

•Annual retention bonuses for the occupation or retention of areas available for exploration and production, at a rate established by the ANP in the relevant bidding guidelines based on the size, location and geological characteristics of the concession block; 

•Special participation charges at a rate ranging from 0 to 40% of the net operating revenues derived from the production of fields that reach high production volumes or profitability, according to the criteria established in the applicable legislation.  In 2010, we paid this tax on 18 of our fields, including Albacora, Albacora Leste, Barracuda, Canto do Amaro, Caratinga, Carmópolis, Cherne, Espadarte, Golfinho, Jubarte, Leste do Urucu, Manati, Marlim, Marlim Sul, Marlim Leste, Miranga, Rio Urucu and Roncador.  Net revenues are gross revenues less royalties paid, investments in exploration, operational costs and depreciation adjustments and applicable taxes.  The Special Participation Tax uses as a reference international oil prices converted to reais  at the current exchange rate; and

•Royalties, to be established in the concession contracts at a rate ranging between 5% and 10% of gross revenues from production, based on reference prices for crude oil or natural gas established by Decree No. 2,705 and ANP regulatory acts.  In establishing royalty rates in the concession contracts, the ANP also takes into account the geological risks and expected productivity levels for each concession.  Virtually all of our crude oil production is currently taxed at the maximum royalty rate.

Law No. 9,478 also requires concessionaires of onshore fields to pay to the owner of the land a participation fee that varies between 0.5% and 1.0% of the net operating revenues derived from the production of the field.

Hydrocarbon Sector Regulatory Reform of 2010

Discoveries of large petroleum and natural gas reserves in the pre-salt areas of the Campos and Santos Basins prompted a proposal to change the legislation regarding oil and gas exploration and production activities.  The proposed legislation, which was submitted by the President of Brazil to the Brazilian Congress on September 1, 2009, was based on studies conducted by an inter-ministerial committee created in July 2008 to consider changes in the regulation of exploration and production activities in pre-salt areas not subject to existing concessions.  Petrobras’ Chief Executive Officer, J.S. Gabrielli de Azevedo and the former Chair of our board of directors and current President of Brazil, Dilma Vana Rousseff, in her capacity as Chief of Staff to former President Luiz Inácio Lula da Silva, were members of this committee.

In 2010, three new laws were enacted to regulate exploration and production activities in pre-salt areas not subject to existing concessions:  Law No. 12,351, Law No. 12,304, and Law No. 12,276.  The enacted legislation does not impact the existing pre-salt concession contracts, which cover approximately 28% of the pre-salt region. 

63

Assignment Agreement (Cessão Onerosa)and Global Offering

Pursuant to Law No. 12,276, enacted on June 30, 2010, we entered into an agreement with the Brazilian federal government on September 3, 2010 (Assignment Agreement), under which the government assigned to us the right to conduct activities for the exploration and production of oil, natural gas and other fluid hydrocarbons in specified pre-salt areas, subject to a maximum production of five billion barrels of oil equivalent. The initial contract price for our rights under the Assignment Agreement was R$74,807,616,407, which was equivalent to U.S.$42,533,327,500 as of September 1, 2010.  See Item 10. “Material contracts—Petrobras—Assignment Agreement.”  In order to ensure transparency, our board of directors created a special committee comprised of minority shareholders’ representatives to monitor the transfer of rights transaction. 

Law No. 12,276 also authorized the Brazilian federal government to subscribe for additional shares of our capital stock in a public offering of our shares.  On September 29, 2010, we issued 2,293,907,960 common shares (including common shares in the form of ADSs) and 1,788,515,136 preferred shares (including preferred shares in the form of ADSs) in a global public offering consisting of a registered offering in Brazil and an international offering that included a registered offering in the United States.  On October 1, 2010, we issued an additional 75,198,838 common shares (including common shares in the form of ADSs) and 112,798,256 preferred shares (including preferred shares in the form of ADSs) pursuant to the exercise of the underwriters’ over-allotment option.  We complied with all of the Brazilian Corporate Law requirements in carrying out the capitalization process, including the protection of the rights of our minority shareholders.  See Item 10. “Memorandum and Articles of Incorporation of Petrobras–Preemptive Rights” for a summary of these requirements.

We applied part of the net proceeds from the global offering to pay the initial purchase price under the Assignment Agreement and to continue to develop all of our business segments in accordance with our Business Plan.

Production-Sharing Contract Regime for Unlicensed Pre-Salt and Potentially Strategic Areas

Law No. 12,351, enacted on December 22, 2010, regulates production-sharing contracts for oil and gas exploration and production in pre-salt areas not under concession and in potentially strategic areas to be defined by the CNPE.  It also calls for the creation of a social fund consisting of resources from the Brazilian federal government’s share in production sharing-contracts, such as subscription bonuses, royalties and revenues, which must be used by the Brazilian federal government to sponsor social development programs.  Under the production-sharing regime, we will be the exclusive operator of all blocks under production-sharing contracts.  The exploration and production rights for these blocks can either be granted to us on an exclusive basis or, in the case where they are not awarded to us on an exclusive basis, the remainder will be offered under public bids.  If offered under public bids, we would be granted a minimum interest to be established by the CNPE that would not be less than 30%, with the additional right to participate in the bidding process allowing us to attempt to increase our interest in those areas.  Under the production-sharing regime, the winner of the bid will be the company that offers the highest percentage of “profit oil,” which is the production of a certain field after deduction of royalties and “cost oil,” which is the cost associated with oil production, to the Brazilian federal government.

Although Law No. 12,351 was enacted, former President Luiz Inácio Lula da Silva vetoed changes to the royalty distribution framework proposed by the Brazilian Congress under this bill and submitted a new proposal to the Brazilian Congress with a royalty rate of 15% applicable to the gross production of oil and natural gas under production-sharing contracts and for the distribution of these royalties among Brazilian federation members.

Establishment of New State-Run Non-0perating Company

Law No. 12,304, enacted on August 2, 2010, authorizes the incorporation of a new state-run non-operating company that will represent the interests of the Brazilian federal government in the production-sharing contracts and will manage the commercialization contracts related to the Brazilian federal government’s share of the “profit oil.”  This new company will participate in operational committees, with a casting voteand veto powers and will manage and control costs arising from production-sharing contracts.  Where production-sharing contracts are concerned, this new company will exercise its specific legal activities alongside the ANP, the independent regulatory agency that regulates and oversees oil and gas activities under all exploration and production regimes, and the CNPE, the entity that sets the guidelines to be applied to the oil and gas sector, including with respect to the new regulatory model.

Natural Gas Law of 2009

In March 2009, the Brazilian Congress enacted a law regulating activities in the gas industry, including transport and commercialization.  The Gas Law created a concession regime for the construction and operation of new pipelines to transport natural gas, while maintaining an authorization regime for pipelines subject to international agreements.  According to the Gas Law, after a certain exclusivity period, operators will be required to grant access to transport pipelines and maritime terminals, except LNG terminals, to third parties in order to maximize utilization of capacity.  Authorizations previously issued by the ANP for natural gas transport will remain valid for 30 years from the date of publication of the Gas Law, and initial carriers were granted exclusivity in these pipelines for 10 years.  The ANP will issue regulations governing third-party access and carrier compensation if no agreement is reached between the parties.

The Gas Law also authorized certain consumers, which can purchase natural gas on the open market or obtain their own supplies of natural gas, to construct facilities and pipelines for their own use in the event local gas distributors controlled by the states, which have monopoly over local gas distribution, do not meet their distribution needs.  These consumers are required to delegate the operation and maintenance of the facilities and pipelines to local gas distributors, but they are not required to sign gas supply agreements with the local gas distributors.

Price Regulation

Until the passage of the Law No. 9,478 in 1997, the Brazilian federal government had the power to regulate all aspects of the pricing of crude oil, oil products, ethanol, natural gas, electric power and other energy sources.  In 2002, the government eliminated price controls for crude oil and oil products, although it retained regulation over certain natural gas sales contracts and electricity.  Also in 2002, the Brazilian federal government established an excise tax on the sale and import of crude oil, oil products and natural gas products (Contribuição de Intervenção no Domínio Econômico, Contribution for Intervention in the Economic Sector, or CIDE). In 2009, the Gas Law authorized the ANP to regulate prices for the use of gas transport pipelines subject to the new concession regime, based on a procedure defined in the Gas Law as a “chamada pública,” and to approve prices submitted by carriers, according to previously established criteria, for the use of new gas transport pipelines subject to the authorization regime. 

Environmental Regulations

All phases of the crude oil and natural gas business present environmental risks and hazards.  Our facilities in Brazil are subject to a wide range of federal, state and local laws, regulations and permit requirements relating to the protection of human health and the environment.  At the federal level, our offshore activities and those that involve more than one Brazilian state are subject to the regulatory authority of the Conselho Nacional doMeio Ambiente (National Council for the Environment, or CONAMA) and to the administrative authority of IBAMA, which issues operating and drilling licenses.  We are required to submit reports, including safety and pollution monitoring reports (IOPP) to IBAMA in order to maintain our licenses.  Onshore environmental, health and safety conditions are controlled at the state rather than federal level, and there is strict liability for environmental damage, mechanisms for enforcement of environmental standards and licensing requirements for polluting activities.

65

Individuals or entities whose conduct or activities cause harm to the environment are subject to criminal and administrative sanctions.  Government environmental protection agencies may also impose administrative sanctions for noncompliance with environmental laws and regulations, including:

•Fines; 

•Partial or total suspension of activities;

•Requirements to fund reclamation and environmental projects;

•forfeit or restriction of tax incentives or benefits;

•Closing of establishments or operations; and

•Forfeiture or suspension of participation in credit lines with official credit establishments.

We are subject to a number of administrative proceedings and civil and criminal claims relating to environmental matters.  See Item 8. “Financial Information—Legal Proceedings—Environmental Claims.”

In 2010, we invested approximately U.S.$1,377 million in environmental projects, compared to approximately U.S.$984 million in 2009 and U.S.$1,075 million in 2008.  These investments were primarily directed at reducing emissions and wastes resulting from industrial processes, managing water use and effluents, remedying impacted areas, implementing new environmental technologies, upgrading our pipelines and improving our ability to respond to emergency situations. 

Health, Safety and Environmental Initiatives  

The protection of human health and the environment is one of our primary concerns, and is essential to our success as an integrated energy company.

As a result of an internal reorganization carried out in 2010, our Health, Safety and Environment (HSE) Management Committee was disbanded and its functions were assigned to a newly-created Technology, Engineering and Services Integration Committee.  This committee is composed of corporate executive managers from both business and services areas and is chaired by our director of services.  The following three committees gather representatives from the business and services areas as well as from subsidiary companies to deal with health, safety, environmental and energy efficiency issues: the HSE Management Committee; the Energy Efficiency, Air Emissions and Climate Change Committee; and the Environmental Licensing and Compensation Committee.  We have also created an Environmental Committee composed of three members of our board of directors.  This committee’s responsibilities include: (i) overseeing and managing environmental and work safety issues affecting us; (ii) establishing measurable environmental targets and ensuring compliance; and (iii) recommending changes in environmental, health and safety policy, if necessary, to our board of directors.  The Environmental Committee charter is awaiting approval by our board of directors.

Our actions to address health, safety and environmental concerns and ensure compliance with environmental regulations involved an investment of approximately U.S.$2,591 million in 2010 and included:

•A HSE management system based on principles of sustainable development which seeks to minimize the impacts of operations and products on health, safety and the environment, reduce the use of natural resources and pollution, and prevent accidents;

66

•ISO 14001 (environment) and OHSAS 18001 (health and safety) certification of our operating units.  As of December 2010, Petrobras had 93% of the total number of 296 certifiable sites in Brazil and abroad certified in accordance with the standards mentioned above.  The Frota Nacionalde Petroleiros (National Fleet of Vessels) has been fully certified by the International Maritime Organization (IMO) International Management Code for Safe Operation of Ships and for Pollution Prevention (ISM Code) since December 1997;

•Regular and active engagement with the MME and IBAMA, including negotiating new environmental compensation regulations and discussing environmental issues connected with new gas pipelines, oil and gas production projects and other aspects of our operations.

•“Climate Change” and “Energy Efficiency” strategic projects, which aim to implement the highest standards in the energy industry regarding the efficient use of energy and greenhouse gas management.  By reducing the environmental impact of our operations, we will contribute to our sustainability and mitigate global climate change.

•A new strategic challenge seeking to maximize energy efficiency and reduce greenhouse gases emission intensity, which was approved by our board of executive officers in November 2010 along with a set of performance indicators with targets to monitor progress with respect to this new challenge.  Our goal is to reach excellence levels in the oil and gas industry and to contribute to business sustainability.

Every project is evaluated to confirm its compliance with all HSE requirements and adoption of the best HSE practices throughout the project’s life cycle.  In addition, we conduct more extensive environmental studies for new projects when required by applicable environmental legislation.

We are committed to reduce greenhouse gas emission intensity from our processes and products, as expressed in our 2020 Strategic Plan.  Our strategy focuses on energy efficiency, energy production from renewable sources and research and technological development.  This strategy aims both at improving business sustainability and mitigating the effects of climate change.

Our Internal Program on Energy Conservation works to improve energy efficiency in all our units.  In 2010, we invested U.S.$71.5 million in energy efficiency projects.  This investment, combined with the improvement of operational procedures, resulted in a reduction of approximately 447 boe/d in energy consumption.  During the last five years, we invested U.S.$245 million in energy efficiency projects, saving 3,478 boe/d in energy consumption.

In 2010, we experienced oil spills totaling 176,388 gallons of crude oil, compared to 67,102 gallons of crude oil in 2009 and 115,179 gallons of crude oil in 2008.

We have maintained oil spill levels well below 1m³ per mmbbl produced, which corresponds to a standard of excellence within the global oil and gas industry.  We continue to evaluate and develop initiatives to address HSE concerns and to reduce our exposure to HSE risks.

Environmental Remediation Plans and Procedures

In 2000, we implemented a company-wide program for environmental management and operational safety (PEGASO) that was designed to identify risks to human life and the environment, control and monitor those risks with safety procedures that comply with best international practices, and maintain a permanent state of readiness for prompt and effective emergency response.  Since 2000, under the PEGASO program, we also have focused our efforts on the prevention of oil spills and our investments in preventive measures have contributed to a 88.7% reduction of oil spills from 37,000 barrels in 2000 to 4,200 barrels in 2010.  From 2000 through 2010, we have developed several projects to improve safety and environmental protection under the PEGASO program both in Brazil and abroad at our international operations, with a total budget of U.S.$5,628 million for the period. 

67

As part of these efforts, we have developed detailed response and remediation contingency plans to be implemented in the event of an oil spill or leak from our offshore operations.  We have more than 660 trained workers available to respond to oil spills 24 hours a day, seven days a week, and we can mobilize an additional 2,000 trained workers for shoreline cleanups on short notice.  While these workers are located in Brazil, they are also available to respond to an offshore oil spill outside of Brazil.  We also have stockpiles of the equipment needed to quickly and effectively contain offshore spills or leaks, including over 440 miles of containment and absorbent booms, over 55,000 gallons of oil dispersants and 318 oil pumps.  Petrobras has 30 dedicated oil spill recovery vessels (OSRVs) fully equipped for oil spill control and fire fighting, as well as 130 additional support and recovery boats and barges available to fight offshore oil spills and leaks 24 hours a day, seven days a week.  In addition, we have contracts with local emergency responders Clean Caribbean and Americas Cooperative in North America and Oil Spill Response Limited in Africa and Asia.  We also maintain relationships with major Oil Spill Response Organizations and other oil companies.

We created ten environmental protection centers in strategic areas in which we operate throughout Brazil in order to ensure rapid and coordinated response to onshore or offshore oil spills.  These regional facilities are supported by 13 local advanced bases dedicated to oil spill prevention, control and response.  Our environmental protection centers and their advance bases would be mobilized in the event of a spill or leak at one of our offshore operations.  Each of our local and regional response centers is self sufficient and available to respond either individually or jointly together with neighboring facilities depending on the severity and scale of the emergency.

In 2010, we carried out a large scale exercise with Clean Caribbean & Americas called International Mobilization, Preparedness & Response Exercise – Mobex in the Amazon Region of Brazil.  Brazilian and international resources as well as several governmental agencies and authorities were engaged in the simulation of a large oil spill on Rio Negro, near Manaus.  The main goal of the exercise was to test the effectiveness of Brazilian and international resources needed to face a Tier 3 environmental emergency.  In 2010, we also conducted regional emergency drills with the Brazilian Navy, the Civil Defense, firefighters, the military police, environmental organizations, and local governmental and community entities.

Insurance

Our insurance programs focus principally on the evaluation of risks and the replacement value of assets, which we believe is customary for our industry.  Under our risk management policy, risks associated with our principal assets, such as refineries, tankers, our fleet and offshore production and drilling platforms, are insured for their replacement value with third-party Brazilian insurers.  Although the policies are issued in Brazil, most of our policies are reinsured abroad with reinsurers rated A- or higher by Standard & Poor’s rating agency or B+ or higher by A.M. Best.  Part of our international operations are insured or reinsured by our Bermudian subsidiary BEAR following the same rating criteria.

Less valuable assets, including but not limited to small auxiliary boats, certain storage facilities, and some administrative installations, are self-insured.  We do not maintain coverage for business interruption, except for a minority of our international operations and a few specific assets in Brazil.  We also do not maintain coverage for our wells for all of our Brazilian operations.  Although we do not insure most of our pipelines, we have insurance against damage or loss to third parties resulting from specific incidents, as well as oil pollution.  We also maintain coverage for risks associated with cargo, hull and machinery risk.  All projects and installations under construction that have an estimated maximum loss above U.S.$60 million are covered by a construction policy.

We maintain insurance coverage for operational third-party liability with respect to our onshore and offshore activities, including environmental risks such as oil spills, in Brazil up to an aggregate policy limit of U.S.$250 million for a period of 12 months.  We also maintain additional protection and indemnity (P&I) marine insurance against third-party liability related to our domestic offshore operations up to an aggregate policy limit of up to U.S.$500 million for a period of 12 months.  In the event of an explosion or similar event at one of our offshore rigs in Brazil, these policies can provide combined third-party liability coverage of up to U.S.$750 million for a period of 12 months.

68

We have operations in more than 20 countries outside Brazil and maintain varying levels of third-party liability insurance for our international operations based on a variety of factors, including our country risk assessments, whether we have onshore and offshore operations and legal requirements imposed by the various countries in which we operate.  We also maintain separate “control-of-well” insurance policies at our international operations to cover liability arising from the uncontrolled eruption of oil, gas, water or drilling fluid with aggregate policy limits up to U.S.$500 million for a period of 12 months depending on the country.  In the U.S. Gulf of Mexico, for example, we maintain third-party liability coverage up to an aggregate policy limit of U.S.$250 million for a period of 12 months, and control-of-well liability insurance up to U.S.$500 million for a period of 12 months.  Depending on the particular circumstances, either of these policies could apply in the event of an explosion or similar event at one of our offshore rigs in the U.S. Gulf of Mexico.

Our domestic and international operational third-party liability policies cover claims made against us by or on behalf of individuals who are not our employees in the event of personal injury or death, subject to the policy limits set forth above.  As a general rule, our service providers are required to indemnify us, for a claim we pay directly to a third party as a result of a court decision holding us liable for the actions of that service provider.  Our service providers may be required to compensate injured third parties directly if the lawsuit is brought against that service provider, or if we join the service provider to a judicial proceeding brought against us, according to the terms of the underlying service contract.

Our operational third-party liability policies in Brazil and outside of Brazil cover environmental damage from oil spills, including liability arising from an explosion or similar sudden and accidental event at one of our offshore rigs.  These operational third-party insurance policies cover litigation, clean-up and remediation costs, but do not cover governmental fines or punitive damages.  As mentioned above, we maintain “control-of-well” insurance policies for our international operations to cover claims for environmental damage from well blow-outs and similar events.  We do not maintain control-of-well insurance for our domestic operations onshore and offshore Brazil.

The premium for renewing our domestic property risk insurance policy for a 12-month period commencing June 2010 was U.S.$45.1 million.  This represented a nominal decrease of 12% over the preceding 12-month period.  The insured value of our assets, in the same period, increased by 13.5% to U.S.$95 billion.  Since 2001, our risk retention has increased and our deductibles may reach U.S.$60 million in certain cases.

Additional Reserves and Production Information

Production of crude oil and natural gas in Brazil is divided into onshore and offshore production, comprising 11% and 89% of total production in Brazil, respectively.  The Campos Basin is one of Brazil’s main and most prolific oil and gas offshore basins, with over 59 hydrocarbon fields discovered, eight large oil fields and a total area of approximately 115,000 km² (28.4 million acres).  In 2010, Campos Basin produced an average 1,676.9 mbbl/d of oil and 13.6 mmm³/d (513.0 mmcf/d) of associated natural gas during 2010, comprising 81.5% of our total production from Brazil. We also conduct limited oil shale mining operations in São Mateus do Sul, in the Paraná Basin of Brazil, and we use oil shale from these deposits to produce synthetic oil and gas.

On December 31, 2010, our estimated proved reserves of crude oil and natural gas in Brazil totaled 12.14 billion barrels of oil equivalent, including: 10.38 billion barrels of crude oil and natural gas liquids and 279.67 bnm³ (10.55 tcf) of natural gas.  As of December 31, 2010, our domestic proved developed crude oil reserves represented 67% of our total domestic proved developed and undeveloped crude oil reserves.  Our domestic proved developed natural gas reserves represented 66% of our total domestic proved developed and undeveloped natural gas reserves.  Total domestic proved crude oil reserves increased at an average annual rate of 4% in the last five years.  Natural gas proved reserves increased at an average annual rate of 4% over the same period. 

69

In 2010, we added 1,372 mmboe of crude oil and natural gas to our domestic proved reserves, mainly due to discoveries in the pre-salt region of the Santos Basin (59% of the total), technical and economic revisions to previous estimates (31% of the total) and, to a lesser extent, increased recovery from existing fields and other new discoveries in exploratory blocks. After production of 797 mmboe in Brazil for the year, these additions to our reserves base in 2010 allowed us to grow our proved reserves in Brazil by 5%.

We calculate reserves based on forecasts of field production, which depend on a number of technical parameters, such as seismic interpretation, geological maps, well tests, reservoir engineering studies and economic data.  All reserve estimates involve some degree of uncertainty.  The uncertainty depends primarily on the amount of reliable geological and engineering data available at the time of the estimate and the interpretation of that data.  Our estimates are thus made using the most reliable data at the time of the estimate, in accordance with the best practices in the oil and gas industry.

Internal Controls over Proved Reserves

The reserves estimation process begins with an initial evaluation of our assets by geophysicists, geologists and engineers.  Corporate Reserves Coordinators (Coordenadores de Reservas Corporativo, or CRCs) safeguard the integrity and objectivity of our reserves estimates by supervising and providing technical support to Regional Reserves Coordinators (Coordenadores de Reservas Regionais, or CRRs) who are responsible for preparing the reserves estimates.  Our CRRs and CRCs have degrees in geophysics, geology, petroleum engineering and accounting and are trained internally and abroad in international reserves estimates seminars.  CRCs are responsible for compliance with Securities and Exchange Commission rules and regulations, consolidating and auditing the reserves estimation process.  The technical person primarily responsible for overseeing the preparation of our domestic reserves is a member of the SPE, with 21 years of experience in the field and has been with Petrobras for 27 years.  The technical person primarily responsible for overseeing the preparation of our international reserves has four years of experience in the field, a doctorate in reservoir engineering and has been with Petrobras for 31 years.  Our reserves estimates are presented to our senior management and submitted to the board of directors for final approval.

D&M reviewed and certified 94.9% of our domestic proved crude oil, condensate and natural gas reserve estimates as of December 31, 2010.  Outside of Brazil, D&M also reviewed and certified 91.2% of our estimates of international proved oil, condensate and natural gas reserves in fields where we are the operator as of December 31, 2010.  The estimates for the certification were performed in accordance with Rule 4-10 of Regulation S-X of the SEC.  For further information on our proved reserves, see “Supplementary Information on Oil and Gas Exploration and Production” beginning on page F-129.

Changes in Proved Reserves

We subtracted a net total of 447.9 mmboe from our company‐wide (consolidated and non‐consolidated entities) proved undeveloped reserves at year‐end 2010 compared to year‐end 2009. Thus, we had a total of 4,354.27 mmboe of proved undeveloped reserves company‐wide at December 31, 2010, compared to 4,802.1 mmboe at December 31, 2009.

Proved undeveloped reserves in Brazil decreased by 500.1 mmboe, while outside of Brazil proved undeveloped reserves increased by 52.2 mmboe, resulting in a net reduction of 447.9 mmboe company‐wide.  The primary factor responsible for the net reduction in our proved undeveloped reserves in Brazil in 2010 compared to 2009 was the conversion of proved undeveloped reserves to proved developed reserves.  We converted a net total of 1,349.1 mmboe of our proved undeveloped reserves to proved developed reserves in Brazil in 2010, mainly through the start‐up of production from the P‐57, FPSO Capixaba and FPSO Cidade de Santos platforms in the Campos and Santos basins.  The volumes we converted from proved undeveloped to proved developed reserves in Brazil exceeded the volumes of proved undeveloped reserves added to our domestic reserves in 2010 as a result of new discoveries in the pre-salt regions of the Santos Basin and technical revisions in the Campos Basin consisting of historical adjustments and increased production from pilot projects.  The 52.2 mmboe net addition of proved undeveloped reserves outside of Brazil was mainly due to newly estimated reserves in Peru.  All reserves volumes described above are “net” to the extent that they only include Petrobras’ proportional participation in  reserve volumes and exclude reserves attributed to our partners.

70

In 2010, we invested a total of U.S.$9.72 billion to convert proved undeveloped reserves into proved developed reserves, of which approximately 92.8% (U.S.$9.02 billion) was invested in Brazil. We converted a total of 1,373.0 mmboe of proved undeveloped reserves to proved developed reserves in 2010, approximately 98.3% (1,349.1 mmboe) of which were Brazilian reserves. In recent years, we have developed projects and increased investments to convert our proved undeveloped reserves into proved developed reserves.

We had a total of 4,354.27 mmboe of proved undeveloped reserves at year‐end 2010, approximately 7.4% (323.52 mmboe) of which have remained undeveloped for five years or more as a result of several factors affecting development and production, including the inherent complexity of ultra‐deepwater developments projects, particularly in Brazil, and constraints in the capacity of our existing infrastructure.  A portion of the 323.52 mmboe of our proved undeveloped reserves that have remained undeveloped for five years or more consist of heavy crude oil located in the Parque das Baleias (Whales Park) area of the Campos Basin offshore Brazil. We originally disclosed these reserves as proved undeveloped reserves between 2003 and 2004 after completing a development plan for the Parque das Baleias region.  However, due to the discovery in 2007 of more valuable light crude oil in the same region, we deliberately postponed production from these proved undeveloped reserves until we could allocate the necessary ultra‐deep water infrastructure and production resources to develop both our existing proved undeveloped reserves of heavy crude oil and our recently discovered pre‐salt light crude oil simultaneously.  We initiated an extended well test in the pre‐salt reservoirs of the Parque das Baleias region in 2008, and in 2010 we started production through FPSO Capixaba.  As a result, we have reclassified a portion of the proved undeveloped reserves in the Parque das Baleias region that have remained undeveloped for five years as proved developed reserves at year‐end 2010.  The remaining portion of our proved undeveloped reserves that have remained undeveloped for five years or more consist of reserves in shallow water fields in the Santos Basin, for which we have invested the necessary infrastructure, including platforms and wells, to be able to begin production in the first half of 2011.

Management’s Discussion and Analysis of Petrobras’ Financial Condition and Results of Operations

You should read the following discussion of our financial condition and results of operations together with our audited consolidated financial statements and the accompanying notes beginning on page F-2 of this annual report.

Overview

We earn income from:

•domestic sales, which consist of sales of oil products (such as diesel oil, gasoline, jet fuel, naphtha, fuel oil and liquefied petroleum gas), natural gas, ethanol, electricity and petrochemical products;

•export sales, which consist primarily of sales of crude oil and oil products;

•international sales (excluding export sales), which consist of sales of crude oil, natural gas and oil products that are purchased, produced and refined abroad; and

•other sources, including services, investment income and foreign exchange gains.

Our expenses include:

•costs of sales (which are composed of labor expenses, operating costs and purchases of crude oil and oil products); maintaining and repairing property, plant and equipment; depreciation and amortization of fixed assets; depletion of oil fields; and exploration costs;

•selling (which include expenses for transportation and distribution of our products), general and administrative expenses; and

•interest expense, monetary and foreign exchange losses.

Fluctuations in our financial condition and results of operations are driven by a combination of factors, including:

•the volume of crude oil, oil products and natural gas we produce and sell;

•changes in international prices of crude oil and oil products, which are denominated in U.S. dollars;

•related changes in the domestic prices of crude oil and oil products, which are denominated in reais;  

•fluctuations in the real/U.S. dollar and to a lesser degree, Argentine peso/U.S. dollar exchange rates; and

•the amount of production taxes that we are required to pay with respect to our operations.

79

Sales Volumes and Prices

The profitability of our operations in any particular accounting period is related to the sales volume of, and prices for, the crude oil, oil products and natural gas that we sell.  Our consolidated net sales in 2010 totaled approximately 1,343,167 thousand barrels of crude oil equivalent, representing U.S.$120,052 million in net operating revenues, compared to 1,215,087 thousand barrels of crude oil equivalent, representing U.S.$91,869 million in net operating revenues in 2009, and approximately 1,227,106 thousand barrels of crude oil equivalent, representing U.S.$118,257 million in net operating revenues in 2008.

As a vertically integrated company, we process most of our crude oil production in our refineries and sell the refined oil products primarily in the Brazilian domestic market.  Therefore, it is oil product prices, rather than crude oil prices, that most directly affect our financial results.  Nonetheless, as crude oil production increases, and as exports increase, crude oil production will have a greater relative importance.

Oil product prices vary over time as the result of many factors, including the price of crude oil.  Over the long term, we intend to sell our products in Brazil at parity with international product prices, however we do not adjust our prices for gasoline, diesel and LPG to reflect short-term volatility in the international markets.  As a result, material rapid or sustained increases or decreases in the international price of crude oil and oil products may result in downstream margins for us that are materially different than those of other integrated international oil companies, within a given financial reporting period. 

The average prices of Brent crude, an international benchmark oil, were approximately U.S.$79.47  per barrel in 2010, U.S.$61.51 per barrel in 2009 and U.S.$96.99 per barrel in 2008.  For December 2010, Brent crude oil prices averaged U.S.$91.80 per barrel.  Brent crude oil prices averaged U.S.$104.97 per barrel in the first quarter of 2011.  We announced price decreases of 4.5% for gasoline and 15% for diesel in the domestic market in June 2009 to reflect international oil product prices.  The increase in the CIDE by the Brazilian federal government fully offset the reduction in gasoline prices and partially offset the reduction in diesel prices.  Since June 2009, there have been no changes in diesel and gasoline prices.

During 2010, approximately 68.2% of our net operating revenues were derived from sales of crude oil and oil products in Brazil, compared to 72.3% in 2009 and 60.9% in 2008.  As export revenues of crude oil and oil products have decreased, domestic sales as a percentage of net operating revenues have increased.

80

Our revenues are principally derived from sales in Brazil.  The following table sets forth our domestic sales by volume of oil products, natural gas and ethanol for each of 2010, 2009 and 2008:

Effect of Taxes on Our Income

In addition to taxes paid on behalf of consumers to federal, state and municipal governments, such as the Imposto sobre Circulação de Mercadorias eServiços, or ICMS, we are required to pay three principal charges on our oil production activities in Brazil: royalties, special participation and retention bonuses.  See Item 4. “Information on the Company—Regulation of the Oil and Gas Industry in Brazil—Exploration and Development Regulation” and Item 3. “Key Information—Risk Factors—Risks Relating to Brazil.”

These charges imposed by the Brazilian federal government are included in our cost of goods sold.  In addition, we are subject to tax on our income at an effective rate of 25% and a social contribution tax at an effective rate of 9%, the standard corporate tax rate in Brazil.  See Note 3 to our audited consolidated financial statements for the year ended December 31, 2010.

Inflation and Exchange Rate Variation

Inflation

Since the introduction of the real as the Brazilian currency in July 1994, inflation in Brazil has remained relatively stable.  Inflation was 5.90% in 2010, 4.31% in 2009 and 5.90% in 2008, as measured by IPCA, the National Consumer Price Index.  Inflation has had, and may continue to have, effects on our financial condition and results of operations.

81

Exchange Rate Variation

Since we adopted the real as our functional currency in 1998, fluctuations in the value of the real against the U.S. dollar have had multiple effects on our results of operations.

Our reporting currency for all periods is the U.S. dollar.  We maintain our financial records in reais, and translate our statements of operations into U.S. dollars at the average rate for the period.  Although a substantial portion of our revenues is in reais, our revenues have been, and continue to be, linked to U.S. dollar-based international prices, since virtually all of our sales are of crude oil or oil products.  When the real strengthens relative to the U.S. dollar as it did from 2003 through the first half of 2008, the effect is to generally increase both revenues and expenses when expressed in U.S. dollars.  When the real  strengthens, prices for our products when expressed in reais  may remain constant, while in dollar terms they increase. 

In 2010, the real  appreciated 13.5% against the U.S. dollar, compared to a depreciation of 8.1% in 2009 and an appreciation of 5.7% in 2008.  When the real  weakens relative to the U.S. dollar, our prices when expressed in dollars decline, unless we raise prices.

Foreign currency translation adjustments have a significant impact on the balance sheet of a company such as ours, whose assets are primarily denominated in reais, but whose liabilities are primarily denominated in foreign currencies.  Asset values decrease in U.S. dollars when the real  depreciates.  The changes in our asset values are charged to shareholders’ equity, but do not necessarily affect our cash flows, since our revenues and cash earnings are to a large degree linked to the U.S. dollar, and a portion of our operating expenses are linked to the real.  See Note 2 of our audited consolidated financial statements for the year ended December 31, 2010, for more information about the translation of Brazilian real amounts into U.S. dollars.

Exchange rate variation also affects the amount of retained earnings available for distribution by us when measured in U.S. dollars.  Amounts reported as available for distribution in our statutory accounting records are calculated in reais  and prepared in accordance with Brazilian accounting principles increase or decrease when measured in U.S. dollars as the real appreciates or depreciates against the U.S. dollar.  In addition, the exchange rate variation creates foreign exchange gains and losses that are included in our results of operations determined in accordance with Brazilian accounting principles and that affect the amount of our unretained earnings available for distribution.

82

Results of Operations

The differences in our operating results from year to year occur as a result of a combination of factors, including primarily: the volume of crude oil, oil products and natural gas we produce and sell, the price at which we sell our crude oil, oil products and natural gas and the differential between the Brazilian inflation rate and the depreciation or appreciation of the real  against the U.S. dollar.

The table below shows the amount by which each of these variables has changed during the last three years:

	2010	2009	2008

Results of Operations—2010 compared to 2009

Virtually all of our revenues and expenses for our Brazilian activities are denominated and payable in reais. When the real appreciates relative to the U.S. dollar, as it did in 2010 (an appreciation of 13.5%) the effect is to generally increase both revenues and expenses when expressed in U.S. dollars. However, the appreciation of the real  against the U.S. dollar affects the line items discussed below in different ways.  As a consequence, the following comparison between our results of operations in 2010 and in 2009 is impacted by the increase in the value of the real  against the U.S. dollar during that period. See Note 2 of our audited consolidated financial statements for the year ended December 31, 2010, for more information about the translation of Brazilian real  amounts into U.S. dollars.

Certain prior year amounts have been reclassified to conform to current year presentation standards. These reclassifications had no impact on our net income.

83

Revenues

Consolidated sales of products and services increased 30.2% to U.S.$150,852 million for 2010 compared to U.S.$115,892 million for 2009.  This increase was primarily a result of:

•higher prices for our exports of oil and oil products, and higher prices for products sold in Brazil that are regularly adjusted to reflect international prices.  In addition, for all products sold in Brazil, the 13.5% average appreciation of the real  against the U.S. dollar increased sales revenues when expressed in U.S. dollars;

•a 12.9% increase in sales volumes in the domestic market as a result of strong economic growth in Brazil, resulting in a 10.7% increase in demand for oil products and a 32.9% increase in demand for natural gas;

•an increase in revenues of U.S.$2,543 million as a result of offshore operations conducted by PifCo for our international trading activities, which increase was largely offset by a U.S.$2,772 million increase in costs of goods sold; and 

•a 2.3% increase in total domestic and international oil and natural gas production.

Included in sales of products and services are the following amounts that we collected on behalf of federal or state governments:

•Imposto sobre Circulação de Mercadorias eServiços  (Domestic State Tax, or ICMS), Programa de Formação do Patrimônio do Servidor Público (Civil Servant Savings Programs, or PASEP), Contribuição para o Financiamento da Seguridade Social (Contribution for the Financing of Social Security, or COFINS) and other taxes on sales of products and services and social security contributions.  These taxes increased 26.5% to U.S.$26,459 million for 2010 compared to U.S.$20,909 million for 2009, primarily due to higher production volumes, higher prices and higher domestic sales volumes; and

•Contribuição de Intervenção no Domínio Econômico (Contribution for Intervention in the Economic Sector, or CIDE), the excise tax applied to the sale and import of crude oil, oil products and natural gas products due to the Brazilian federal government, which increased 39.4% to U.S.$4,341 million for 2010 compared to U.S.$3,114 million for 2009, primarily due to higher production volumes and higher domestic sales volumes.

Net operating revenues increased 30.7% to U.S.$120,052 million for 2010 compared to U.S.$91,869 million for 2009 due to the increases mentioned above.

Cost of Sales (Excluding Depreciation, Depletion and Amortization)

Cost of sales for 2010 increased 43.5% to U.S.$70,694 million compared to U.S.$49,251 million for 2009. This increase was principally a result of:

•a 52.4% (U.S.$7,596 million) increase in the cost of imports, primarily due to the growing demand for oil products in Brazil, mainly of diesel and jet fuel.  The growth in Brazilian demand was met by  higher volumes of imports, purchased at prevailing international prices, which increased during the year; and

•a 40.5% (U.S.$3,116 million) increase in production taxes and charges in 2010 compared to 2009, reflecting higher international oil benchmark prices upon which such taxes and charges are based.  The taxes and charges are as follows: 

oRoyalties, which increased from U.S.$3,558 million in 2009 to U.S.$5,340 million in 2010, an increase of 50.1%  in 2010 as compared to 2009;

84

oSpecial participation charge (a charge payable in the event of high production or profitability from our fields), which increased from U.S.$4,094 million in 2009 to U.S. $5,395 million in 2010, an increase of 31.8% in 2010 as compared to 2009; and

oand costs associated with rental fees of areas, which increased from U.S.$46 million in 2009 to U.S.$80 million in 2010, an increase of 73.2% in 2010 as compared to 2009.

The increase in production taxes and charges in 2010 was due to a 29.3% increase in the reference price for domestic oil, which averaged U.S.$70.34 for 2010 compared to U.S.$54.40 for 2009, reflecting the increase in average  prices for crude oil on the international market.

Depreciation, Depletion and Amortization

We calculate depreciation, depletion and amortization of most of our exploration and production assets using the units of production method. Depreciation, depletion and amortization expenses increased 18.4% to U.S.$8,507 million for 2010 compared to U.S.$7,188 million for 2009, due to higher capital expenditures and increased oil and gas production.

Exploration, including Exploratory Dry Holes

Exploration costs, including costs for exploratory dry holes, increased 16.4% to U.S.$1,981 million for 2010 compared to U.S.$1,702 million for 2009. Excluding the impact of the appreciation of the real, exploration, including exploratory dry holes, remained relatively constant during 2010 compared to 2009.

Impairment of Oil and Gas Properties

In 2010, we recorded an impairment charge of U.S.$402 million compared to U.S.$319 million for 2009. This higher impairment charge was primarily attributable to producing properties in Brazil with high maturity levels and insufficient oil and gas production to cover production costs (U.S.$346 million), as well as the impairment of assets held for sale, particularly in the refining and distribution segments in Argentina (U.S.$56 million).

By comparison, the impairment charge in 2009 was primarily attributable to producing properties in Brazil with high maturity levels and insufficient oil and gas production to cover production costs, in particular Petrobras’ Agua Grande field.

See Notes 9(c) and 20(b) to our consolidated financial statements for the year ended December 31, 2010.

Selling, General and Administrative Expenses

Selling, general and administrative expenses increased 27.9% to U.S.$8,977 million for 2010 compared to U.S.$7,020 million for 2009.

•Selling expenses increased 33.7% to U.S.$4,514 million for 2010 compared to U.S.$3,375 million for 2009. This increase was primarily attributable to the impact of the appreciation of the real  as well as higher expenses associated with the costs related to the 12.9% increase in domestic sales volumes.  The higher sales volumes led to higher freight expenses, an increase in the use and cost of third-party services, and higher expenses related to NGL reconverter ships.

•General and administrative expenses increased 22.4% to U.S.$4,463 million for 2010 compared to U.S.$3,645 million for 2009. This increase in general and administrative expenses was primarily attributable to the impact of the appreciation of the real as well as higher personnel expenses due to an increased workforce and pay raises.

85

Research and Development Expenses

Research and development expenses increased 45.8% to U.S.$993 million for 2010 compared to U.S.$681 million for 2009. This higher expense was primarily due to increased average sales prices of oil, which is the basis for a fixed 0.5% provision for expenses on research and development investment in Brazilian universities and institutions as required by our Brazilian oil and gas concession agreements.

Employee Benefit Expense for Non-Active Participants

Employee benefit expense for non-active participants consists of financial costs associated with our expected pension and health care costs of retired employees. Our employee benefit expense for non-active participants increased 4.6% (U.S.$752 million for 2010 compared to U.S.$719 million for 2009) remaining relatively constant during the year.

Other Operating Expenses

Other operating expenses increased 15.0% to U.S.$3,588 million for 2010 compared to U.S.$3,120 million for 2009.

The most significant changes between 2010 and 2009 are as follows: 

•a U.S.$412 million loss due to the exchange of equity method investments resulting from the integration of petrochemical investments in Braskem. See Note 17(c) of our audited consolidated financial statements for the year ended December 31, 2010, for more information;

•a 27.5% (U.S.$152 million) increase in expense for institutional relations and cultural projects, to U.S.$705 million for 2010 compared to U.S.$553 million for 2009;

•a 24.8% (U.S.$69 million) increase in expenses related to collective bargaining agreements, to U.S.$347 million for 2010 compared to U.S.$278 million for 2009;

•a 15.4% (U.S.$28 million) increase in expense for health, safety and environment (HSE), to U.S.$210 million for 2010 compared to U.S.$182 million for 2009; and

•a 8.1% (U.S.$25 million) increase in expense for marking inventory to market value, to U.S.$333 million for 2010 compared to U.S.$308 million for 2009.

These increases were partially offset by:

•a 22.5% (U.S.$304 million) decrease in expense for losses and contingencies related to legal proceedings, to U.S.$1,045 million for 2010 compared to U.S.$1,349 million for 2009;

•a 44.5% (U.S.$186 million) decrease in expense for unscheduled stoppages of plant and equipment, to U.S.$232 million for 2010 compared to U.S.$418 million for  2009; and

•a 44.8% (U.S.$138 million) decrease in operating expenses at thermoelectric power plants, to U.S.$170 million for 2010 compared to U.S.$308 million for 2009.

Equity in Results of Non-Consolidated Companies

Equity in results of non-consolidated companies increased 163.1% to a gain of U.S.$413 million for 2010 compared to a gain of U.S.$157 million for 2009, primarily due to better results generated by gas distribution companies and companies operating outside of Brazil.

86

Financial Income

We derive financial income from several sources, including interest on cash and cash equivalents. The majority of our cash equivalents are short-term Brazilian federal government securities, including securities indexed to the U.S. dollar. We also hold U.S. dollar deposits.

Financial income increased 38.5% to U.S.$2,630 million for 2010 compared to U.S.$1,899 million for 2009. This increase was primarily attributable to higher income related to increased marketable securities due to the Assignment Agreement (a U.S.$309 million increase) and income related to financial investments (a U.S.$273 million increase). A breakdown of financial income is set forth in Note 13 of our consolidated financial statements for the year ended December 31, 2010.

Financial Expenses

Financial expenses increased 26.9% to U.S.$1,643 million for 2010 compared to U.S.$1,295 million for 2009. This increase was primarily attributable to increased financial expenses related to our debt (a U.S.$1,722 million increase), partially offset by higher capitalized interest income (which resulted in a U.S.$1,129 million decrease in financial expenses for 2010 as compared to 2009) and by reduced losses on derivative instruments (a U.S.$254 million decrease). A breakdown of financial expense is set forth in Note 13 of our consolidated financial statements for the year ended December 31, 2010.

Monetary and Exchange Variation

Monetary and exchange variation increased to a gain of U.S.$714 million for 2010 compared to a loss of U.S.$175 million for 2009.  The gain in 2010 compared to the loss in 2009 was primarily due to lower foreign exchange losses on net monetary assets denominated in U.S. dollars.

Other Taxes

Other taxes, consisting of various taxes on financial transactions, increased 57.1% to U.S.$523 million for 2010 compared to U.S.$333 million for 2009. This increase was primarily attributable to the impact of the appreciation of the real  and also to losses on the recoverable amounts of tax credits.

Other Expenses, Net

Other expenses, net are primarily composed of gains and losses recorded on sales of fixed assets and certain other non-recurring charges. Other expenses, net amounted to a gain of U.S.$82 million for 2010 compared to a loss of U.S.$61 million for 2009, primarily due to the U.S.$147 million provision for losses for the Pasadena Refinery in the United States made in the first quarter of 2009.

Income Tax (Expense) Benefit

Income before income taxes and non-controlling interest increased 17.1% to U.S.$25,831 million for 2010 compared to U.S.$22,061 million for 2009. Income tax expense increased 21.3% to U.S.$6,356 million for 2010, compared to U.S.$5,238 million for 2009, primarily due to the increase of taxable income. The reconciliation between the tax calculated based upon statutory tax rates to income tax expense and effective rates is set forth in Note 3 of our consolidated financial statements for the year ended December 31, 2010.

 

87

Net Income by Business Segment

We measure performance at the segment level on the basis of net income.  Following is a discussion of the net income of our six business segments at December 31, 2010, compared to December 31, 2009.

	Year Ended December 31,
	2010	2009	Percentage Change
	(U.S.$ million)		(%)
Exploration and Production	16,351	9,683	68.9
Refining, Transportation and Marketing	1,539	6,563	(76.6)
Distribution	727	634	14.7
Gas and Power	734	340	115.9
International	799	(154)	(618.8)
Corporate	(453)	(1,116)	(59.4)
Eliminations	(513)	(446)	15.0
Net income	19,184	15,504	23.7

Exploration and Production

Our Exploration and Production segment includes our exploration, development and production activities in Brazil, sales and transfers of crude oil in domestic and foreign markets, transfers of natural gas to our Gas and Power segment and sales of oil products produced at natural gas processing plants.

The consolidated net income from our Exploration and Production segment increased from U.S.$16,351 million in 2010 compared to U.S.$9,683 million in 2009 as a result of the following:

•An increase in the price of crude oil, from U.S.$54.22 per barrel in 2009 to U.S.$74.66 per barrel in 2010, as a result of higher international prices.  The higher price also reflected a reduction in the spread between the average price of domestic oil sold/transferred and the average Brent price, from U.S.$ 7.29/bbl in 2009 to U.S.$ 4.81/bbl in 2010, primarily due to the higher demand for heavy oil as compared to light oil;

•A 1.6% increase in oil and LNG production; and

•Reduced losses and contingencies related to legal proceedings, particularly a charge of U.S.$1,034 million related to a special participation in the Marlim field that was charged to operations in 2009.

These effects were partially offset by:

•Higher production taxes, which increased from U.S.$20.51 per barrel to U.S.$24.64 per barrel  due to higher oil prices;

•An increase in lifting costs from U.S.$ 8.78 per barrel in 2009 to U.S.$ 10.03 in 2010, primarily as a result of the revaluation of the real  and increased maintenance costs in our fields; and

•Non-recurring expenses of U.S.$275 million related to project financings in the Barracuda and Caratinga fields.

See Item 4. “Information on the Company—Overview of the Group—Changes in Proved Reserves” for information on changes in proved reserves.

88

Refining, Transportation and Marketing

Our Refining, Transportation and Marketing segment (RTM) 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.  RTM purchases crude oil from E&P and imports oil to blend with our domestic oil.  Additionally, RTM purchases oil products in the international markets to meet excess product demand in the domestic market.  RTM acquires crude oil and oil products at the international price, either from E&P or from international markets, and sells products in Brazil at a price that we expect will equal international prices in the long run. For gasoline, diesel and residential LPG, however, the product prices in Brazil can lag the international markets. Depending on the impact of this lag effect, RTM’s earnings may differ from international refining margins. In 2009, falling acquisition costs and a stable price for some of our products led to higher margins relative to international levels, while in 2010, this effect was reversed. 

The lower net income for RTM in 2010, at U.S.$1,539 million compared to U.S.$6,563 million in 2009, was largely due to the higher oil acquisition/transfer costs and higher oil product import costs from both E&P and from international markets during 2010, which were not fully offset by the higher sales prices of diesel, gasoline and residential LPG.

These effects were partially offset by higher domestic oil product sales volumes (mainly for gasoline, diesel and jet fuel) and an increase in domestic prices for oil products, which are indexed to international prices.

An increase in refinery costs, from U.S.$3.21 to U.S.$4.33 per barrel, as a result of the strengthening of the real, increased refinery maintenance, and higher personnel and third party service costs also contributed to the reduced income. 

Distribution

Our Distribution segment comprises the oil product and ethanol distribution activities conducted by our 100% owned subsidiary, Petrobras Distribuidora S.A. – BR, in Brazil.

The increase in net income from our Distribution segment in 2010 compared to 2009 was primarily due to higher sales margins and an 8% increase in sales volumes.  These effects were partially offset by higher third-party service and personnel expenses and by a provision for tax contingencies.

The Distribution segment accounted for 38.8% of the national fuel distribution market in 2010, compared to 38.6% in 2009.

Gas and Power

Our Gas and Power segment consists principally of the purchase, sale, transportation and distribution of natural gas produced in or imported into Brazil. Additionally, this segment includes our participation in local gas companies, , thermoelectric power generation and our two domestic fertilizer plants.

The improved result for our Gas and Power segment for 2010 compared to 2009 was due to:

•Higher natural gas sales, led by growth in the industrial sector and thermo-electric demand;

•Increased demand for power generation, which led to higher income from thermoelectric generation;

•Increased fixed revenue from energy auctions;

•Lower acquisition/transfer costs of domestic natural gas reflecting international prices; and

89

•Appreciation of the real  against the dollar.

These effects were partially offset by:

•Increasing LNG import costs and imports of gas from Bolivia; and

•Higher selling expenses related to NGL reconverter ships.

International

Our International segment comprises our activities in countries other than Brazil, which include exploration and production, refining, transportation and marketing, distribution and gas and power.

The improved result in our International segment in 2010 compared to 2009 was due to higher commodities prices in 2010 as well as higher sales volumes of crude oil resulting largely from the start-up of production in Akpo, Nigeria in March 2009.

Results of Operations—2009 compared to 2008

Virtually all of our revenues and expenses for our Brazilian activities are denominated and payable in reais.  When the real  weakens relative to the U.S. dollar as it did in 2009 (a depreciation of 8.1%), the effect is to generally decrease both revenues and expenses when expressed in U.S. dollars.  However, the depreciation of the real against the U.S. dollar affects the line items discussed below in different ways.  The following comparison between our results of operations in 2009 and 2008 is impacted by the decrease in the value of the real against the U.S. dollar during that period.  See Note 2 of our audited consolidated financial statements for the year ended December 31, 2009, for more information about the translation of Brazilian real amounts into U.S. dollars.

Certain prior year amounts have been reclassified to conform to current year presentation standards.  These reclassifications had no impact on our net income.

Revenues

Net operating revenues decreased 22.3% to U.S.$91,869 million for 2009 compared to U.S.$118,257 million for 2008. This decrease was primarily attributable to a reduction in average sales prices of crude oil and natural gas in domestic and international markets and a 1.9% reduction in sales volumes in the domestic market.

Consolidated sales of products and services decreased 20.9% to U.S.$115,892 million for 2009 compared to U.S.$146,529 million for 2008 due to the reductions mentioned above.

Included in sales of products and services are the following amounts that we collected on behalf of federal or state governments:

•Imposto sobre Circulação de Mercadorias e Serviços (Domestic State Tax, or ICMS), Programa de Formação do Patrimônio do Servidor Público (Civil Servant Savings Programs, or PASEP), Contribuição para o Financiamento da Seguridade Social (Contribution for the Financing of Social Security, or COFINS) and other taxes on sales of products and services and social security contributions.  These taxes decreased 16.5% to U.S.$20,909 million for 2009 compared to U.S.$25,046 million for 2008, primarily due to lower prices and lower domestic sales volumes; and

•Contribuição de Intervenção no Domínio Econômico (Contribution for Intervention in the Economic Sector, or CIDE), the excise tax applied to the sale and import of crude oil, oil products and natural gas products due to the Brazilian federal government, which decreased 3.5% to U.S.$3,114 million for 2009 compared to U.S.$3,226 million for 2008, primarily due to lower domestic sales volumes.

90

Cost of Sales (Excluding Depreciation, Depletion and Amortization)

Cost of sales for 2009 decreased 32.4% to U.S.$49,251 million compared to U.S.$72,865 million for 2008. This decrease was principally a result of:

•a 46.5% (U.S.$12,516 million) decrease in the cost of imports due to lower volumes and prices; 

•a 38.5% (U.S.$3,531 million) decrease in costs for our international trading activities due to decreased offshore operations conducted by PifCo;

•a 36.5% (U.S.$4,465 million) decrease in production taxes and charges that include royalties, which decreased 35.7% (U.S.$1,988 million) in 2009 compared to 2008; special participation charge, which decreased 37.4% (U.S.$2,464 million) in 2009 compared to 2008; and rental fees for concession areas, which decreased 22.3% (U.S.$13 million) in 2009 compared to 2008. The decrease in production taxes and charges in 2009 was due to a 32.2% reduction in the reference price used to calculate royalties for our domestic production, which averaged U.S.$54.40 for 2009 compared to U.S.$80.25 for 2008, reflecting the average Brent price on the international market; and

•a 60.6% (U.S.$1,165 million) decrease in costs related to the generation and purchase of electricity for sale.

Depreciation, Depletion and Amortization

We calculate depreciation, depletion and amortization of most of our exploration and production assets using the units of production method.  Depreciation, depletion and amortization expenses increased 21.3% to U.S.$7,188 million for 2009 compared to U.S.$5,928 million for 2008, due to higher capital expenditures and increased oil and gas production.

Exploration, including Exploratory Dry Holes

Exploration costs, including costs for exploratory dry holes, decreased 4.1% to U.S.$1,702 million for 2009 compared to U.S.$1,775 million for 2008.  Excluding the impact of the depreciation of the real, exploration, including exploratory dry holes, remained relatively constant during 2009 compared to 2008.

Impairment of Oil and Gas Properties

For 2009, we recorded an impairment charge of U.S.$319 million compared to U.S.$519 million for 2008. This lower charge was primarily due to the higher impairment on exploration and production assets recorded in 2008 as a result of the decrease of the estimated future oil prices.  The impairment charge in 2008 was primarily attributable to goodwill impairment at Petrobras’ indirect subsidiary in the United States, Pasadena Refining System (U.S.$223 million) and to impairment at Petrobras’ Guajá field and other producing properties in Brazil due to reduced year-end international oil prices (U.S.$171 million).  The impairment charge in 2009 was primarily attributable to producing properties in Brazil and principal amounts were related to Petrobras’ Agua Grande field.  In 2009 the petroleum and natural gas fields that presented losses already had high maturity levels and, consequently, produced insufficient petroleum and gas to cover production costs.  This factor had a reducing effect on the economic analysis that led to the recording of a provision for loss through devaluation in some fields.  See Notes 9(b) and 18(a) to our consolidated financial statements for the year ended December 31, 2009.

Selling, General and Administrative Expenses

Selling, general and administrative expenses decreased 5.5% to U.S.$7,020 million for 2009 compared to U.S.$7,429 million for 2008.

Selling expenses decreased 4.0% to U.S.$3,375 million for 2009 compared to U.S.$3,517 million for 2008.  Excluding the impact of the depreciation of the real, selling expenses remained relatively constant during 2009 compared to 2008.

91

General and administrative expenses decreased 6.8% to U.S.$3,645 million for 2009 compared to U.S.$3,912 million for 2008.  Excluding the impact of the depreciation of the real, general and administrative expenses remained relatively constant during 2009 compared to 2008.

Research and Development Expenses

Research and development expenses decreased 27.6% to U.S.$681 million for 2009 from U.S.$941 million for 2008.  This lower expense was primarily due to decreased oil prices, which is the basis for a fixed 0.5% provision for expenses on research and development investment in Brazilian universities and institutions as required by our Brazilian oil and gas concession agreements (U.S.$267 million).  

Employee Benefit Expense for Non-Active Participants

Employee benefit expense for non-active participants consists of financial costs associated with our expected pension and health care costs of retired employees.  Our employee benefit expense for non-active participants decreased 14.5% to U.S.$719 million for 2009 compared to U.S.$841 million for 2008.  Excluding the impact of the depreciation of the real, the employee benefit expense for non-active participants remained relatively constant during 2009 compared to 2008.

Other Operating Expenses

Other operating expenses increased 17.1% to U.S.$3,120 million for 2009 from U.S.$2,665 million for 2008.

The most significant changes between 2009 and 2008 are described below: 

•a 378.7% (U.S.$1,034 million) increase in expense due to special participation taxes from the Marlim field in September 2009, pursuant to an agreement between Petrobras and the ANP; and

•a 283.5% (U.S.$309 million) increase in expense for unscheduled stoppages of plant and equipment, to U.S.$418 million for 2009 compared to U.S.$109 million for 2008.  In 2009, 75% of the unscheduled stoppages occurred in our Exploration and Production segment, 21% in Refining, Transportation and Marketing, and 3% in International;

These increases were partially offset by:

•a 43.5% (U.S.$237 million) decrease in expense for marking inventory to market value, to U.S.$308 million for 2009 compared to U.S.$545 million for 2008;

•a 90.3% (U.S.$214 million) decrease in expense for contractual fines, to U.S.$23 million for 2009 compared to U.S.$237 million for 2008;

•a 18.1% (U.S.$122 million) decrease in expense for institutional relations and cultural projects, to U.S.$553 million for 2009 compared to U.S.$675 million for 2008;

•a 13.7% (U.S.$44 million) decrease in expenses related to collective bargaining agreements, to U.S.$278 million for 2009 compared to U.S.$322 million for 2008;

•a 10.7% (U.S.$37 million) decrease in operating expense at thermoelectric power plants, to U.S.$308 million for 2009 compared to U.S.$345 million for 2008; and

92

•15.0% (U.S.$32 million) decrease in expense for health, safety, and environment (HSE), to U.S.$182 million for 2009 compared to U.S.$214 million for 2008.

Equity in Results of Non-Consolidated Companies

Equity in results of non-consolidated companies increased to a gain of U.S.$157 million for 2009 compared to a loss of U.S.$21 million for 2008, primarily as a result of a U.S.$216 million increase in gains in investments in affiliated companies in the petrochemical sector, compared to losses in 2008 due to foreign exchange variation on U.S. dollar denominated debt.

Financial Income

We derive financial income from several sources, including interest on cash and cash equivalents.  The majority of our cash equivalents are short-term Brazilian federal government securities, including securities indexed to the U.S. dollar. We also hold U.S. dollar deposits.

Financial income increased 15.7% to U.S.$1,899 million for 2009 compared to U.S.$1,641 million for 2008.  This increase was primarily attributable to increased financial investments and other investments (U.S.$445 million increase) and to higher income on marketable securities (U.S.$209 million increase), partially offset by lower gains on derivative instruments (U.S.$390 million decrease).  A breakdown of financial income is set forth in Note 13 of our consolidated financial statements for the year ended December 31, 2009.

Financial Expenses

Financial expenses increased 52.7% to U.S.$1,295 million for 2009 compared to U.S.$848 million for 2008.  This increase was primarily attributable to increased financial expenses related to our corporate debt and project financings (U.S.$771 million increase).  These increases were partially offset by a 45.4% (U.S.$659 million) increase in capitalized interest.  A breakdown of financial expenses is set forth in Note 13 of our consolidated financial statements for the year ended December 31, 2009.

Monetary and Exchange Variation

Monetary and exchange variation decreased to a loss of U.S.$175 million for 2009 compared to a gain of U.S.$1,584 million for 2008.  The loss in 2009 relates to the foreign exchange losses on net foreign assets denominated in U.S. dollars that were almost entirely offset by the foreign exchange gains on net debt and by the monetary variation on Banco Nacional de Desenvolvimento Econômico e Social—BNDES (Brazilian Development Bank) financing.

Other Taxes

Other taxes, consisting of various taxes on financial transactions, decreased 23.1% to U.S.$333 million for 2009 compared to U.S.$433 million for 2008, due to lower income tax withholdings on the 2009 distribution of dividends from foreign subsidiaries (U.S.$40 million of the total decrease), and also to lower PIS and COFINS taxes on non-core business activities and to the reduction of the IOF tax, a tax payable on financial transactions (U.S.$26 million decrease).

Other Expenses, Net

Other expenses, net are primarily composed of gains and losses recorded on sales of fixed assets and certain other non-recurring charges. Other expenses, net decreased 72.9% to a loss of U.S.$61 million for 2009 compared to a loss of U.S.$225 million for 2008, which included a U.S.$97 million write-off of Block 31 in Ecuador in the fourth quarter.  Other expenses, net in 2009 was primarily attributable to a U.S.$147 millionloss from the purchase of the remaining shares of the Pasadena Refinery in the first quarter of 2009, partially offset by a U.S.$83 million gain related to donations and subsidies in the third quarter of 2009.

93

Income Tax (Expense) Benefit

Income before income taxes and non-controlling interest decreased 18.3% to U.S.$22,061 million for 2009 compared to U.S.$26,992 million for 2008. Income tax expense decreased 43.4% to U.S.$5,238 million for 2009, compared to U.S.$9,259 million for 2008, due primarily to: the reduction of taxable income; the increase of foreign income subject to different tax rates (U.S.$531 million increase); to the decrease of change in valuation allowance tax expense (U.S.$906 million decrease) and to the increase of certain tax benefits related to the provisioning of interest on shareholders’ equity (U.S.$336 million increase).  The reconciliation between the tax calculated based upon statutory tax rates to income tax expense and effective rates is set forth in Note 3 of our consolidated financial statements for the year ended December 31, 2009.

Net Income by Business Segment

We measure performance at the segment level on the basis of net income.  Following is a discussion of the net income of our six business segments at December 31, 2009, compared to December 31, 2008.

The segments "Refining, Transportation and Marketing" and "Gas and Power" were previously reported as "Supply" and "Gas and Energy", respectively, without representing changes in the factors used to identify the included activities, and in the amounts previously reported.

	Year Ended December 31,
	2009	2008	Percentage Change
	(U.S.$ million)		(%)
Exploration and Production	9,683	21,031	(54.0)
Refining, Transportation and Marketing	6,563	(2,036)	(422.3)
Distribution	634	839	(24.4)
Gas and Power	340	(183)	(285.8)
International	(154)	(808)	(80.9)
Corporate	(1,116)	(57)	(1,857.9)
Eliminations	(446)	93	(579.6)
Net income	15,504	18,879	(17.9)

Exploration and Production

Our Exploration and Production segment includes our exploration, development and production activities in Brazil, sales and transfers of crude oil in domestic and foreign markets, transfers of natural gas to our Gas and Power segment and sales of oil products produced at natural gas processing plants.

The 54.0% reduction in consolidated net income for our Exploration and Production segment in 2009 compared to 2008 reflects the decline in international prices, and the non-recurring expense of U.S.$1,034 million related to the settlement of a dispute with the National Petroleum, Natural Gas and Biofuels Agency (“ANP”) regarding the calculation of special participation in the Marlin field.

These effects were partially offset by a 6.3% increase in oil and NGL production and lower production taxes.

The spread between the average domestic oil sale/transfer price and the average Brent price narrowed from U.S.$15.44/bbl in 2008 to U.S.$7.29/bbl in 2009 and reflects the recovery in the international market of heavy oil in relation to light oil since our production consists mainly of heavy oil.

See Item 4. “Information on the Company—Overview of the Group—Changes in Proved Reserves” for information on changes in proved reserves.

94

Refining, Transportation and Marketing

Our Refining, Transportation and Marketing segment includes refining, logistics, transportation, export and the purchase of crude oil, as well as the purchase and sale of oil products and fuel ethanol.  Additionally, this segment includes the petrochemical division, which includes investments in domestic petrochemical companies.

The improved result from our Refining, Transportation and Marketing segment in 2009 compared to 2008 was largely due to our domestic pricing policy for diesel, gasoline and LPG, which allowed us to avoid transferring the short-term volatility for these products in the international market to the Brazilian market.  In 2009, international prices and, consequently, oil acquisition/transfer costs and oil product import costs for our refining segment, declined much more rapidly than the prices at which we sold our principal products domestically.  As a result, our refining margins improved substantially.  In 2008, the opposite occurred, as we did not raise prices at the same pace as the international market, and our downstream margins were reduced by higher oil acquisition/transfer costs. 

These effects were partially offset by a reduction in the average realization price due to lower export prices and lower domestic sales prices adjusted to international price levels.

Distribution

Our Distribution segment comprises the oil product and ethanol distribution activities conducted by our majority owned subsidiary, Petrobras Distribuidora S.A.– BR, in Brazil.

The decrease in net income from Distribution in 2009 compared to 2008 was primarily due to a reduction in the average realization price and the impact of depreciation of the real.  This effect was partially offset by a 13.3% upturn in sales volume, reflecting the consolidation of Alvo Distribuidora.

This segment accounted for 38.6% of the total Brazilian fuel distribution market in 2009 compared to 34.9% in 2008.

Gas and Power

Our Gas and Power segment consists principally of the purchase, sale, transportation and distribution of natural gas produced in or imported into Brazil.  Additionally, this segment includes our participation in domestic natural gas transportation, natural gas distribution and thermoelectric power generation.

The improved result from our Gas and Power segment was due to lower costs for purchasing electricity from third parties to fulfill our contractual commitments, lower import/transfer costs of natural gas reflecting international prices, increased fixed income from electricity sales and exports and a reduction in fines paid for failure to deliver contracted amounts of electricity attributable to improvements in our natural gas infrastructure in 2008.

These effects were partially offset by reduced thermoelectric output as a result of abundant rainfall supplying Brazil’s hydroelectric power plants, and a decline in natural gas sales volumes.

International

The International segment comprises our activities in countries other than Brazil, which include exploration and production, refining, transportation and marketing, distribution and gas and power.

The improved results from the International segment in 2009 compared to 2008 were due to better gross margins in refinery operations in the United States and Japan, higher sales volumes, a reduction of losses with inventory devaluation, impairment expenses and losses such as those related to the write-off of Block 31 in Ecuador which was recorded in 2008.  These effects were offset by declining margins as a result of lower international oil prices.

(1)                  As a vertically integrated company, not all of our segments have significant third-party revenues.  For example, our Exploration and Production segment accounts for a large part of our economic activity and capital expenditures, but has little third party revenues.

(2)                  Revenues from commercialization of oil to third parties are classified in accordance with the points of sale, which could be either the Exploration and Production or Refining, Transportation and Marketing segments.

(3)                  In order to align the financial statements of each business segment with the best practices of companies in the oil and gas sector and to improve our management’s understanding, since the first quarter of 2006 we have switched to allocating all financial results and items of a financial nature to the corporate level, including prior years.

(4)                  The financial data for 2010, 2009 and 2008 was prepared in light of changes in business segments due to the transfer of the fertilizer business from the “Refining, Transportation and Marketing” segment to the “Gas and Power” segment.

Management’s Discussion and Analysis of PifCo’s Financial Condition and Results of Operations

Overview

PifCo is our wholly owned subsidiary.  Accordingly, PifCo’s financial position and results of operations are significantly affected by our decisions.  PifCo’s ability to meet its outstanding debt obligations depends on a number of factors, including:

•our financial condition and results of operations;

•our willingness to continue to make loans to PifCo and provide PifCo with other types of financial support;

•PifCo’s ability to access financing sources, including the international capital markets and third-party credit facilities; and

•PifCo’s ability to transfer our financing costs to us.

PifCo earns income from:

•sales of crude oil and oil products to us;

•sales of crude oil and oil products to third parties and affiliates; and

•the financing of sales to us, inter-company loans to us and investments in marketable securities and other financial instruments.

PifCo’s operating expenses include:

•cost of sales, which is comprised mainly of purchases of crude oil and oil products;

•selling, general and administrative expenses; and

•financial expense, mainly from interest on its lines of credit and capital markets indebtedness, sales of future receivables and inter-company loans from us.

As discussed below under “Purchases and Sales of Crude Oil and Oil Products,” PifCo is gradually reducing its sales of crude oil and oil products to us and will gradually reduce its sales of crude oil and oil products to third parties, and will eventually cease these commercial operations altogether in order to become our finance subsidiary.  As a result, both its income and its operating expenses from oil sales and trading activities will gradually decrease to zero while its income and expenses from financing operations will likely increase.  PifCo’s ability to meet its outstanding debt obligations has historically been and will continue to be dependent on our financial conditions, results of operation and our willingness to provide PifCo with various types of financial support, among the other factors discussed above.

97

Purchases and Sales of Crude Oil and Oil Products

PifCo purchases crude oil and oil products from us to hold in inventory and for sale outside Brazil.  Additionally, PifCo sells and purchases crude oil and oil products to and from third parties and related parties, mainly outside Brazil.  In April 2010, PifCo began selling crude oil and oil products to us under terms that allow payment in up to approximately 30 days, without a premium.  Prior to April 2010, however, we paid for shipments of crude oil and oil products that PifCo sold to us over a period of up to 330 days, which allowed us sufficient time to assemble the necessary documentation under Brazilian law to commence the payment process for our shipments.  During this period, PifCo typically financed the purchase of crude oil and oil products through either funds previously provided by us or third-party trade finance arrangements.  Under such arrangements, the premium resulting from the difference between the amount PifCo paid for crude oil and oil products and the amount we paid for that same crude oil and oil products was deferred and recognized as part of PifCo’s financial income on a straight-line basis over the period in which our payments to PifCo came due.  Since shipments to us with payment terms over a period of up to 330 days have been discontinued, the corresponding working capital is no longer required. PifCo’s commercial operations, including those with us, are carried out under normal market conditions and at commercial prices.

PifCo will gradually reduce both its sales of crude oil and oil products to us and its sales of crude oil and oil products to third parties, and will eventually cease these commercial operations altogether. At that time, PifCo will become a finance subsidiary functioning as a vehicle for us to raise capital for our operations outside of Brazil through the issuance of debt securities in the international capital markets, among other means.  Our support of PifCo’s debt obligations has been and will continue to be made through unconditional and irrevocable guaranties of payment.

Results of Operations—2010 compared to 2009

Net (Loss) Income

PifCo had a loss of U.S.$262 million in 2010 compared to a net income of U.S.$487 million in 2009.

Sales of Crude Oil and Oil Products and Services

PifCo’s sales of crude oil and oil products and services increased 20.5% to U.S.$34,759 million in 2010 compared to U.S.$28,850 million in 2009.  This increase was primarily due to higher sales prices resulting from a 29.2% increase in the average prices of Brent crude oil, to U.S.$79.47 per barrel in 2010 compared to U.S.$61.51 per barrel in 2009.

Cost of Sales

Cost of sales increased 23.0% to U.S.$34,230 million in 2010 compared to U.S.$27,825 million in 2009.  This increase was proportional to the increase in sales of crude oil and oil products and services and was primarily due to the same reasons, in addition to higher average inventory price formation for oil and oil products acquired during periods of higher international prices.

Selling, General and Administrative Expenses

PifCo’s selling, general and administrative expenses consist primarily of shipping costs and fees for services, including accounting, legal and rating services.  These expenses increased 15.3% to U.S.$482 million in 2010 compared to U.S.$418 million in 2009.  Shipping costs increased 15.0% to U.S.$338 million in 2010 compared to U.S.$294 million in 2009, primarily due to changes in international market trends and shipping routes.

98

Other Operating Expenses

PifCo’s other operating expenses consist primarily of inventory impairment adjustments for its inventory of crude oil and oil products.  These expenses increased 65.5% to U.S.$48 million in 2010 compared to U.S.$29 million in 2009.

Financial Income

PifCo’s financial income consists of the financing of sales to us, inter-company loans to us, investments in marketable securities and other financial instruments.  PifCo’s financial income decreased 52.7% to U.S.$944 million in 2010 compared to U.S.$1,997 million in 2009.  This decrease was primarily due to reduced income from the financing of sales to us and decreased marketable securities income.

Financial Expenses

PifCo’s financial expenses consist of interest paid and accrued on PifCo’s outstanding indebtedness, other fees associated with PifCo’s issuance of debt and other financial instruments.  PifCo’s financial expenses decreased 42.5% to U.S.$1,202 million in 2010 compared to U.S.$2,090 million in 2009.  This decrease was primarily due to the extinguishment of PifCo´s inter-company loans from us.

Results of Operations—2009 compared to 2008  

Net Income (loss)

PifCo had net income of U.S.$487 million in 2009 compared to a loss of U.S.$772 million in 2008.

Sales of Crude Oil and Oil Products and Services

PifCo’s sales of crude oil and oil products and services decreased 32.0% to U.S.$28,850 million in 2009 compared to U.S.$42,443 million in 2008.  This decrease was primarily due to lower sales prices resulting from a 37% decrease in the average prices of Brent crude oil, to U.S.$62 per barrel in 2009 compared to U.S.$97 per barrel in 2008.  This decrease was partially offset by a 11% increase in PifCo’s sales volume, primarily due to increase sales of crude oil and oil products purchased from third parties and affiliates and subsequently sold to Petrobras.

Cost of Sales

Cost of sales decreased 34.1% to U.S.$27,825 million in 2009 compared to U.S.$42,231 million in 2008.  This decrease was proportional to the decrease in sales of crude oil and oil products and services and was primarily due to the same reasons, in addition to lower average inventory price formation for oil and oil products acquired during period s of low international prices.

Selling, General and Administrative Expenses

PifCo’s selling, general and administrative expenses consist primarily of shipping costs and fees for services, including accounting, legal and rating services.  These expenses decreased 25.6% to U.S.$418 million in 2009 compared to U.S.$562 million in 2008.  Shipping costs decreased 36.1% to U.S.$289 million in 2009 compared to U.S.$452 million in 2008, primarily due to lower international freight prices.

Other Operating Expenses

PifCo’s other operating expenses consist primarily of inventory impairment adjustments for its inventory of crude oil and oil products.  These expenses decreased 95.0% to U.S.$29 million in 2009 compared to U.S.$577 million in 2008, due to a reduction in the value of its inventory resulting from lower international oil prices.

99

Financial Income

PifCo’s financial income consists of the financing of sales to us, inter-company loans to us, investments in marketable securities and other financial instruments.  PifCo’s financial income decreased 14.1% to U.S.$1,997 million in 2009 compared to U.S.$2,325 million in 2008.  This decrease was primarily due to decreased derivative income for exchange traded contracts resulting from volatility in average international oil prices.  This decrease was partially offset by an increase in marketable securities income.

Financial Expenses

PifCo’s financial expense consists of interest paid and accrued on PifCo’s outstanding indebtedness, other fees associated with PifCo’s issuance of debt and other financial instruments.  PifCo’s financial expenses decreased 3.7% to U.S.$2,090 million in 2009 compared to U.S.$2,170 million in 2008.  This decrease was primarily due to decreased inter-company loans from Petrobras and was partially offset by an increase in interest expenses relating to issuances of Global Notes and lines of credit in 2009.

Our principal uses of funds are for capital expenditures, dividend payments and repayment of debt.  In 2008, 2009 and 2010, we met these requirements with internally generated funds, short-term debt, long-term debt  and cash generated by capital increases.  For 2011 and beyond, we believe internally generated funds and increases in debt, together with our strong position of cash and cash equivalents, will continue to allow us to meet our current capital requirements.  In 2011, our major cash needs are for our budgeted  capital expenditures of U.S.$54 billion, the remaining part of announced dividends, interest on shareholders’ equity of U.S.$2,231 million and principal payments of U.S.$2,988 million on our long-term debt, leasing and project financing obligations.

Financing Strategy

The objective of our financing strategy is to help us achieve the targets set forth in our 2010-2014 Business Plan released on June 18, 2010, which provides for capital expenditures of U.S.$224 billion from 2010 through 2014.  Our 2010-2014 Business Plan forecasts that we will supplement internally generated cash flow with proceeds from the capital increase that we completed on October 1, 2010, and increases in our net debt, which should allow us to maintain a sound capital structure that stays within our targeted financial leverage ratios. We will raise debt capital through a variety of medium and long-term financing arrangements, including the issuance of bonds in the international capital markets, supplier financing, project financing and bank financing. We will continue our policy of extending the term of our debt maturity profile. 

For 2011, we intend to fund our financial needs through a combination of drawing down our year-end cash balances and existing credit facilities, as well as contracting new debt from a broad range of traditional funding sources, including global debt capital markets, export credit agencies, non-Brazilian government development banks, the BNDES, and Brazilian and international commercial banks.  As of May 10, 2011, we have financed part of our needs for 2011 through a U.S.$6,000 million offering of Global Notes in the international capital markets and U.S.$620.5 million from lines of credit and export credit agencies.

Our business plan for 2011 through 2015 is currently under review by our board of executive officers and will be announced as soon as the board completes its review.

Government Regulation

We are required to submit our annual capital expenditures budget (Plano de Dispêndio Global, or PDG) to the Brazilian Ministry of Planning, Budget and Management, and the Ministry of Mines and Energy.  Following review by these agencies, the Brazilian Congress must approve the budget.  Although the total level of our annual capital expenditures is regulated, the specific application of funds is left to our discretion.  Since mid-1991, we have obtained substantial amounts of our financing from the international capital markets, mainly through the issuance of commercial paper and short, medium and long-term notes, and have increasingly been able to raise long-term funds for large capital expenditure items such as rigs and platforms.

The Brazilian Ministry of Planning, Budget and Management controls the total amount of medium and long-term debt that we and our Brazilian subsidiaries can incur through the annual budget approval process.  Before issuing medium and long-term debt, we and our Brazilian subsidiaries must also obtain the approval of the National Treasury Secretariat.

All of our foreign currency denominated debt, as well as the foreign currency denominated debt of our Brazilian subsidiaries, requires registration with the Central Bank.  The issuance of debt by our international subsidiaries, however, is not subject to registration with the Central Bank or approval by the National Treasury Secretariat.  In addition, all issuances of medium and long-term notes and debentures require the approval of our board of directors.  Borrowings that exceed the approved budgeted amount for any year also require approval of the Brazilian Senate.

Sources of Funds

Our Cash Flow 

On December 31, 2010, we had cash and cash equivalents of U.S.$17,633 million compared to U.S.$16,169 million at December 31, 2009.

Operating activities provided net cash flows of U.S.$28,495 million for 2010 compared to U.S.$24,920 million for 2009.  Cash generated by operating activities was mainly impacted by net operating revenues, which increased U.S.$28,183 million during 2010 compared to 2009 as a result of higher production volumes and higher prices for our products, reflecting price recovery in the international markets. 

Net cash provided by financing activities amounted to U.S.$35,386 million for 2010 compared to net cash provided by financing activities of U.S.$16,935 million for 2009.  This increase was primarily due to the capital increase of U.S.$30,563 million generated by the global offering.  Net cash from financing activities was reduced by the payment of dividends of U.S.$5,299 million compared to U.S.$7,712 million in 2009.  We typically pay all dividends in the year following the announcement of the corresponding results.  In 2010, we paid dividends related to 2009 earnings as well as a large portion of interest on shareholders’ equity related to 2010 earnings in advance of the close of our 2010 fiscal year.

Our net debt decreased to U.S.$36,701 million as of December 31, 2010 compared to U.S.$41,733 million as of December 31, 2009, primarily due to the increase of cash raised by the global offering. 

Short-Term Debt

Our outstanding short-term debt serves mainly to support our working capital and our imports of crude oil and oil products, and is provided almost entirely by international banks. On December 31, 2010, our total short-term debt amounted to U.S.$8,960 million compared to U.S.$8,431 million on December 31, 2009.

Long-Term Debt

Our outstanding long-term debt consists primarily of securities issued in the international capital markets, debentures issued in the domestic capital markets, amounts outstanding under facilities guaranteed by export credit agencies and multilateral agencies, loans from the BNDES and other financial institutions and project financings.  Our total long-term debtamounted to U.S.$60,471 million on December 31, 2010 compared to U.S.$49,041 million on December 31, 2009.  This increase was primarily due to international borrowings, mainly in the form of drawings on financing obtained from the China Development Bank, as well as proceeds in the form of Export Credit Notes obtained from the Banco do Brasil and the Caixa Econômica Federal. These financial resources will be used primarily for the development of projects related to oil and gas production, for the construction of ships and pipelines, as well as for the expansion of industrial units.  See Note 12 to our consolidated financial statements for the year ended December 31, 2010, for more information.

(2)                  Issued by PifCo on September 27, 2006 in the amount of ¥ 35 billion, with support from us through a standby purchase agreement.

In addition, on January 27, 2011, PifCo issued U.S.$6,000 million aggregate principal amount in a multi-tranche offering of Global Notes, due between 2016 and 2041 that bear interest at rates from 3.875% to 6.750% per year.

Off Balance Sheet Arrangements

As of December 31, 2010, neither we nor PifCo had off-balance sheet arrangements that have, or are reasonably likely to have, a material effect on our financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.

Uses of Funds

CapitalExpenditures 

We invested a total of U.S.$45,078 million in 2010, a 28.3% increase compared to our investments of U.S.$35,134 million in 2009.  Our investments in 2010 were primarily directed toward increasing production, modernizing our refineries and expanding our pipeline transportation and distribution systems.  Of the total capital expenditures in 2010, U.S.$22,222 million was invested in exploration and development projects, including investments financed through project financing.

102

The following table sets forth our consolidated capital expenditures (including project financings and investments in thermoelectric power plants) for each of our business segments for 2010, 2009 and 2008:

	For the Year Ended December 31
	2010	2009	2008
	(U.S.$ million)
Exploration and Production	22,222	16,488	14,293
Refining, Transportation and Marketing	15,356	10,466	7,234
Distribution	482	369	309

Distribution	52	31	20
Gas and Power	13	58	52
Corporate	752	584	874
Total	45,078	35,134	29,874

On June 18, 2010, we announced our 2010-2014 Business Plan, which contemplates total budgeted capital expenditures of U.S.$224 billion from 2010 to 2014, approximately U.S.$212.3 billion of which will be directed towards our activities in Brazil, while U.S.$11.7 billion will be directed to our activities abroad.  We expect that the majority of our capital expenditures from 2010 to 2014, approximately U.S.$118.8 billion, will be directed towards exploration and production, of which U.S.$108.2 billion is slated for our activities in Brazil (U.S.$33 billion of which is dedicated to the pre-salt reservoirs).

Our 2010-2014 Business Plan contemplates greater domestic capital expenditures for our oil and gas activities in Brazil.  We estimate that of the U.S.$212.3 billion in domestic capital expenditures through 2014, at least U.S.$142.2 billion (67%) will be utilized to pay for equipment and services provided by Brazilian contractors, suppliers and other service providers.

Our capital expenditure budget for 2011, including our project financings, is U.S.$54 billion, allocated as follows: 

•Exploration and Production segment: 46%;

•Refining, Transportation and Marketing segment: 40%;

•Distribution segment: 1%;

•Gas and Power segment: 5%;

•International segment: 6%;

•Corporate segment: 1%; and

•Our subsidiary Petrobras Biocombustível: 1%.

We plan to meet our budgeted capital expenditures primarily through internally generated cash, issuances in the international capital markets, project finance loans, commercial bank loans and other sources of capital.  Our actual capital expenditures may vary substantially from the projected numbers set forth above as a result of market conditions and the cost and availability of the necessary funds.

103

Dividends

Our shareholders approved a total dividend distribution of R$11,728  million (U.S.$6,780  million) for 2010 earnings at the Ordinary General Meeting held on April 28, 2011, which includes interest on shareholders’ equity already approved by our board of directors.  We paid U.S.$5,857  million of this amount to shareholders in the form of interest on shareholders’ equity in May, August, November and December of 2010 and March of 2011, in advance of the close of our 2010 fiscal year.  The remaining U.S.$923  million in dividends and interest on shareholders’ equity relating to our 2010 earnings will be paid by June 27, 2011, restated according to the SELIC rate from December 31, 2010 to the date of payment.  The total amount of 2010 dividends approved by our shareholders is equivalent to R$1.19 (U.S.$0.69) per common and preferred share (R$2.38 (U.S.$1.38)per common and preferred ADS).

The dividends we pay to shareholders depend on our earnings and other factors.  Under our bylaws and the Brazilian Corporate Law applicable to a company with a class of non-voting shares, such as ours, our shareholders are entitled to a mandatory minimum dividend of at least 25% of our adjusted net profit for the fiscal year.  In 2010 and 2009, we paid the mandatory minimum dividend of 25% to our shareholders.

For more information on our dividend policy, including a description of the minimum preferred dividend to which our preferred shareholders are entitled under our bylaws, see “Mandatory Distribution” and “Payment of Dividends and Interest on Shareholders’ Equity” in Item 10. “Additional Information—Memorandum and Articles of Incorporation of Petrobras.” 

PifCo

Overview

PifCo finances its oil trading activities principally through commercial banks, including lines of credit, as well as through inter-company loans from us and the issuance of notes in the international capital markets.  As an offshore non-Brazilian company, PifCo is not legally obligated to receive prior approval from the Brazilian National Treasury before incurring debt or registering debt with the Central Bank.  As a matter of policy, however, the issuance of any debt follows the recommendation by any of our Chief Financial Officer, executive board or board of directors, depending on the aggregate principal amount and the tenor of the debt to be issued.

PifCo’s Cash Flow

At December 31, 2010, PifCo had cash and cash equivalents of U.S.$1,197 million compared to U.S.$953 million at December 31, 2009. 

PifCo’s operating activities provided net cash of U.S.$10,245 million in 2010 compared to provided net cash of U.S.$9,397 million in 2009, primarily due to an increase in cash received from related parties in 2010 as a result of the reduction of the period for payment for sales of crude oil and oil products to us from 330 days to 30 days as of April 2010.

PifCo’s investing activities used net cash of U.S.$1,655 million in 2010 compared to using net cash of U.S.$486 million in 2009, primarily as a result of an increase in the amount of loans to related parties.

PifCo’s financing activities used net cash of U.S.$8,345 million in 2010 compared to using net cash of U.S.$8,245 million in 2009, primarily due to payments of loans to us.

104

PifCo’s Accounts Receivable

Accounts receivable from related parties decreased 63.1% to U.S.$5,891 million at December 31, 2010, from U.S.$15,986 million at December 31, 2009, primarily due to an increase in cash received from related parties in 2010 as a result of the reduction of the period for payment for sales of crude oil and oil products to us from 330 days to 30 days as of April 2010.

PifCo’s Short-Term Borrowings

PifCo’s short-term borrowings are denominated in U.S. dollars and consist of short-term lines of credit, loans from financing institutions and the short-term portion of long-term lines of credit loans from financing institutions, sale of right to future receivables and senior notes.  At December 31, 2010, PifCo had borrowed U.S.$2,303 million under lines of credit and loans from financing institutions, including the current portion of long-term lines of credit and senior loans, compared to U.S.$1,892 million borrowed at December 31, 2009.  The weighted average annual interest rate on these short-term borrowings was 2.73% at December 31, 2010, compared to 2.33% at December 31, 2009.  At December 31, 2010, PifCo had fully utilized all of its available lines of credit.

PifCo’s notes payable to related parties consisted of notes payable to us.  At December 31, 2009, PifCo had loans in a total amount of U.S.$7,862 million.  PifCo has no outstanding balance with us at December 31, 2010.

PifCo’s Long-Term Borrowings

At December 31, 2010, PifCo had long-term borrowings outstanding in financing institutions of:

•U.S.$880 million (U.S.$2,010 million in current portion) in long-term lines of credit due between 2012 and 2017 compared to U.S.$1,396 million at December 31, 2009.  At December 31, 2010, PifCo had utilized all available funds from lines of credit; and

•U.S.$215 million (U.S.$72 million in current portion) under the loan agreement with Malha Gas Investment Co. Ltd. (M-GIC), which acts as a Facility Agent for the Japan Bank for International Cooperation (JBIC).  This loan bears interest at Libor plus 0.8% per year, payable semi-annually.  The principal amount has been paid semi-annually starting on December 15, 2009 and will mature on through December 15, 2014.

•At December 31, 2010, PifCo also had outstanding:

•U.S.$194 million (U.S.$69 million current portion) in connection with Petrobras’ export prepayment program, consisting of Senior Trust Certificates due 2015 that bear interest at the rate of 6.436% and Senior Trust Certificates due 2013 that bear interest at the rate of 3.748%;

•U.S.$10,712 million in Global Notes, due between 2013 and 2040 that bear interest at rates from 5.75% to 9.125% per year.  Interest on these notes is paid semi-annually and the proceeds were used for general corporate purposes, including the financing of the purchase of oil product imports, the repayment of existing trade-related debt and inter-company loans and the repayment of bridge loans incurred at the beginning of 2009; and

•U.S.$430 million (¥35 billion) in Japanese Yen Bonds issued in September 2006 and due September 2016.  The issue was a private placement in the Japanese market with a partial guaranty from the Japan Bank for International Cooperation (JBIC).  The bonds bear interest at the rate of 2.15% per year, payable semi-annually.  On the same date, PifCo entered into a swap agreement with Citibank, swapping the total amount of this debt to a U.S. dollar denominated debt.

105

PifCo’s outstanding position at December 31, 2010 in irrevocable letters of credit was U.S.$94 million compared to U.S.$556 million at December 31, 2009, supporting crude oil and oil products imports and services.  At December 31, 2010, PifCo had standby committed facilities available in the amount of U.S.$721 million, which are not committed to any specific use.  PifCo has not drawn down amounts under these facilities, and, as of the date of this filing, PifCo has not scheduled a date for the drawdown.

The following table sets forth the sources of PifCo’s current and long-term debt at December 31, 2010 and 2009:

Critical Accounting Policies and Estimates

The following discussion describes those areas that require the most judgment or involve a higher degree of complexity in the application of the accounting policies that currently affect our financial condition and results of operations.  The accounting estimates we make in these contexts require us to make assumptions about matters that are highly uncertain.  In each case, if we had made other estimates, or if changes in the estimates occur from period to period, our financial condition and results of operations could be materially affected.

The discussion addresses only those estimates that we consider most important based on the degree of uncertainty and the likelihood of a material impact if we used a different estimate.  There are many other areas in which we use estimates about uncertain matters, but the reasonably likely effect of changed or different estimates is not material to our financial presentation.

107

Oil and Gas Reserves

Evaluations of oil and gas reserves are important for the effective management of exploration and production assets.  They are used to make investment decisions about oil and gas properties.  Oil and gas reserve quantities are also used as the basis for calculation of unit-of-production rates for depreciation and evaluation for impairment.  Oil and gas reserves are divided between proved and unproved reserves.  Proved reserves are estimated quantities of crude oil, natural gas and natural gas liquids that geological and engineering data demonstrate with reasonable certainty are economically producible in future years from known reservoirs under existing economic and operating conditions and government regulations, i.e., prices and costs as of the date the estimate is made.  Unproved reserves are those with less than reasonable certainty of recoverability and are classified as either probable or possible.  Probable reserves are reserves that are more likely to be recovered than not.  Possible reserves are less likely to be recovered than probable reserves.

The estimation of proved reserves is an ongoing process that takes into account engineering and geological information such as well logs, pressure data and fluid sample core data.  Proved reserves can also be divided in two categories: developed and undeveloped.  Developed proved reserves are expected to be recovered from existing wells including line pack or when the costs necessary to put them in production are relatively low, or through installed extraction equipment and infrastructure operational at the time of the reserves estimate if the extraction is by means not involving a well.  For undeveloped proved reserves, significant investments are necessary, including drilling new wells and installing production or transportation facilities.

We use the “successful efforts” method to account for our exploration and production activities.  Under this method, costs are accumulated on a field-by-field basis with certain exploratory expenditures and exploratory dry holes being expensed as incurred.  Exploratory wells that find oil and gas in an area requiring major capital expenditure before production can begin are evaluated annually to ensure that commercial quantities of reserves have been found or that additional exploration work is under way or planned in a timeframe reasonable for the Petrobras development cycle and with consideration to ANP timing requirements.  Exploratory well costs not meeting either of these criteria are charged to expense.  Costs of productive wells and development dry holes are capitalized and amortized on the unit-of-production method because it provides a more timely accounting of the success or failure of our exploration and production activities.

Impact of Oil and Gas Reserves on Depreciation and Depletion

The calculation of unit-of-production depreciation and depletion is a critical accounting estimate that measures the depreciation and depletion of exploration and production assets.  It is the ratio of (i) actual volumes produced to (ii) total proved developed reserves (those proved reserves recoverable through existing wells with existing equipment and operating methods) applied to (iii) asset cost.  Proved undeveloped reserves are considered in the amortization of leasehold acquisition costs.  The volumes produced and asset cost are known and while proved developed reserves have a high probability of recoverability they are based on estimates that are subject to some variability.  This variability may result in net upward or downward revisions of proved reserves in existing fields, as more information becomes available through research and production.  As a result of these revisions, we increased our proved reserves by 435.4 mmboe in 2010, 1,646.1 mmboe in 2009 and 162.7 mmboe in 2008.

Impact of Oil and Gas Reserves and Prices on Testing for Impairment

At December 31, 2010, our property, plant, and equipment, net of accumulated depletion, amounted to U.S.$219 billion.   A substantial part of this amount consisted of oil and gas producing properties.  These properties are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable.  We estimate the future and discounted cash flows of the affected properties to judge the recoverability of carrying amounts.  In general, analyses are based on proved reserves, except in circumstances where it is probable that additional non-proved reserves will be developed and contribute to cash flows in the future; the percentage of probable reserves that we include in cash flows does not exceed our past success ratios in developing probable reserves.

108

We perform asset valuation analyses on an ongoing basis as a part of our management program. These analyses monitor the performance of assets against corporate objectives.  They also assist us in reviewing whether the carrying amounts of any of our assets may not be recoverable.  In addition to estimating oil and gas reserve volumes in conducting these analyses, it is also necessary to estimate future oil and gas prices.

In general, we do not view temporarily low oil prices as a trigger event for conducting impairment tests.  The markets for crude oil and natural gas have a history of significant price volatility.  Although prices will occasionally drop precipitously, industry prices over the long term will continue to be driven by market supply and demand fundamentals.  Accordingly, any impairment tests that we perform make use of our long-term price assumptions for the crude oil and natural gas markets.  These are the same price assumptions that are used in our planning and budgeting processes and our capital investment decisions, and they are considered to be reasonable, conservative estimates given market indicators and past experience.  Significantly lower future oil and gas prices could lead to impairments in the future, if such decreases were considered to be indicative of long-term trends.  In addition, significant changes in production curve expectation, discount and/or required production and lifting costs, could affect impairment analysis.  While such uncertainties are inherent to this estimation process, the amount of impairment charges in past years has been small relative to the total value of oil and gas producing properties: U.S.$402 million in 2010, U.S.$319 million in 2009 and U.S.$519 million in 2008.  Based on our experience, we believe that future variability in estimates will have a small impact on both assets and expense.

Pension and Other Post-Retirement Benefits

The determination of the expense and liability relating to our pension and other post-retirement benefits involves the use of judgment in the determination of actuarial assumptions.  These include estimates of future mortality, withdrawal, changes in compensation and discount rate to reflect the time value of money as well as the rate of return on plan assets.  These assumptions are reviewed at least annually and may differ materially from actual results due to changing market and economic conditions, regulatory events, judicial rulings, higher or lower withdrawal rates or longer or shorter life spans of participants.

We account for our Employees’ Post-Retirement Benefits and Other Benefits, in accordance with the procedure established by Codification Topic 715.  These standards require that we recognize the over-funded or under-funded status of each of our defined benefit pension and other post-retirement benefit plans as an asset or liability and to reflect changes in the funded status through “Accumulated other comprehensive income,” as a separate component of stockholder’s equity.

According to the requirements of Codification Topic 715, the discount rate should be based on present value for settling the pension obligation.  The use of the precepts of Codification Topic 715 in Brazil, which has been subject to inflation from time to time, creates certain issues to the extent that the ability for a company to settle a pension obligation at a future point in time may not exist because long-term financial instruments of suitable grade may not exist locally.

Although the Brazilian market has been demonstrating signs of stabilization as reflected in market interest rates, interest rates may be unstable.

We adopt a mortality table relating to actuarial assumptions of our pension and healthcare plans in Brazil, which reflects changes with respect to the profile of employees, retirees and pensioners, based on longevity, age of invalidity and invalid mortality tables.

The progressive increase in longevity has direct impact on the plan’s estimated and provisioned volume of commitments and obligations and in our liabilities under the line “Employees’ post-retirement benefits obligation– Pension” and our shareholders’ equity under the line “Post-retirement benefit reserves adjustments net of tax—pension cost.”

“Post-retirement benefit reserves adjustments net of tax—pension cost” are values calculated as the difference between the forecasted restatement of the net value of the obligations according to the actuarial assumptions and the variations effectively occurring over time.  These amounts are to be amortized and posted to the results of subsequent fiscal years over the average life expectancy of the pension plan’s members.  See Note 15 to our audited consolidated financial statements for the year ended December 31, 2010.

Litigation, Tax Assessments and Other Contingencies

Claims for substantial amounts have been made against us arising in the normal course of business.  We are sometimes held liable for spills and releases of oil products and chemicals from our operating assets.  In accordance with the guidance provided by U.S. GAAP, we accrued for these costs when it is probable that a liability has been incurred and reasonable estimates of the liability can be made.  At December 31, 2010, we had accrued U.S.$760 million for litigation contingencies.  Significant management judgment is required to comply with this guidance and it includes management’s discussion with our attorneys, taking into account all of the relevant facts and circumstances.  We believe that payments required to settle the amounts related to these claims, in case of loss, will not vary significantly from our estimated costs, and thus will not have a material adverse effect on our operations or cash flows. In past periods, the difference between the actual payout and the amount of the provision liability, with respect to contingency estimation, has been insignificant, with no material income statement impact in the period of the payout.  In the last five years, our annual cash payouts for contingencies relating to claims against us, the parent company, reached an average of U.S.$386 million per year.

Asset Retirement Obligations and Environmental Remediation 

Under various contracts, permits and regulations, we have material legal obligations to remove equipment and restore the land or seabed at the end of operations at production sites.  Our most significant asset removal obligations involve removal and disposal of offshore oil and gas production facilities worldwide.  We accrue the estimated discounted costs of dismantling and removing these facilities at the time of installation of the assets.  We also estimate costs for future environmental clean-up and remediation activities based on current information on costs and expected plans for remediation.  The aggregate amount of estimated costs on a discounted basis for asset retirement and environmental remediation provision at December 31, 2010 was U.S.$3,194 million.  Estimating asset retirement, removal and environmental remediation costs requires performing complex calculations that necessarily involve significant judgment because our obligations are many years in the future, the contracts and regulation have vague descriptions of what removal and remediation practices and criteria will have to be met when the removal and remediation events actually occur and asset removal technologies and costs are constantly changing, along with political, environmental, safety and public relations considerations.  Consequently, the timing and amounts of future cash flows are subject to significant uncertainty.  However, given the significant amount of time to the ultimate retirement date, any modifications in technological specifications, legal requirement, or other matters, would not have a materially adverse effect on any one reporting period.

In 2010, we reviewed and revised our estimated costs associated with well abandonment and the demobilization of oil and gas production areas, considering new information about date of expected abandonment and revised cost estimates to abandon.  The changes to estimated asset retirement obligation were principally related to declaration of new fields as economically viable, certain changes in revised cost estimates to abandon provided by non-operated joint-ventures.  A summary of the annual changes in the abandonment provisions is presented in Note 9(b) to our audited consolidated financial statements, as of December 31, 2010.

Derivative Transactions

Codification Topic 815 requires that we recognize all derivatives as either assets or liabilities in the balance sheet and measure those instruments at fair value.  Accounting for derivative transactions requires us to employ judgment to arrive at assumptions to compute fair market values, which are used as the basis for recognition of the derivative instruments in the financial statements.  Such measurement may depend on the use of estimates such as estimated future prices, long-term interest rates and inflation indices, and becomes increasingly complex when the instrument being valued does not have counterparts with similar characteristics traded in an active market.

110

In the course of our business we have entered into contracts that meet the definition of derivatives under Codification Topic 815, certain of which have not qualified to receive hedge accounting.  For the majority of these contracts, the estimates involved in the calculations for the fair value of such derivative instruments have not been considered likely to have a material impact in our financial position had we used different estimates, due to the majority of our derivative instruments being traditional over the counter instruments with short term maturities.

Impact of New Accounting Standards

Brazilian GAAP Is in the Process of Adopting IFRS Principles

Enacted in 2007, Law No. 11,638/07 amended the Brazilian Corporate Law to permit Brazilian GAAP to converge with International Financial Reporting Standards, or IFRS, as issued by the International Accounting Standards Board, or IASB.  The adoption of IFRS in Brazil is mandatory for the year ended December 31, 2010, and it is tax neutral in accordance with current income tax legislation. We chose to present our financial statements in Brazil for the first time in accordance with IFRS in the first quarter of 2010. Our financial statements prepared in accordance with U.S. GAAP were not affected by the adoption of IFRS other than with respect to dividends payable and profit sharing payable to our employees, which are based on net income as calculated under IFRS.  We are currently evaluating the possibility of discontinuing U.S. GAAP reporting and adopting IFRS as issued by the IASB as the basis for the audited consolidated financial statements contained in our annual report on Form 20-F for the year ended December 31, 2011. 

In 2008, Provisional Measure No. 449/08 was enacted to create a transitional tax regime that allowed the changes to Brazilian GAAP brought by Law No. 11,638/07 to be tax neutral until further legislation regulating the tax effects of the new accounting principles becomes effective.  The adoption of the transitional tax regime was optional for the fiscal year ended December 31, 2009 and mandatory as from fiscal year ended December 31, 2010.  The temporary tax effects caused by the adoption of this transitional tax regime are reported in our financial statements as deferred income taxes.

ASU 2009-16

The Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2009-16 in December 2009. This standard removes the concept of a Qualifying Special Purpose Entity (“QSPE”) and the exception for QSPE consolidation and clarifies the requirements for financial asset transfers eligible for sale accounting. ASU 2009-16 was adopted on January 1, 2010, and did not impact our results of operations, financial position or liquidity.

ASU 2009-17

The FASB issued ASU 2009-17 in December 2009. This standard became effective for us on January 1, 2010. ASU 2009-17 requires the enterprise to qualitatively assess if it is the primary beneficiary of a variable-interest entity (“VIE”), and, if so, the VIE must be consolidated. Additionally, this Statement requires continuous assessments of whether an enterprise is the primary beneficiary of a VIE. ASU 2009-17 was adopted on January 1, 2010, and did not impact our results of operations, financial position or liquidity.

ASU 2010-20

The FASB issued ASU 2010-20 in July 2010. ASU 2010-20 enhances the disclosures required for financing receivables and allowances for credit losses under FASB Accounting Standards Codification 310, Receivables. Most of the existing disclosures have been amended to require information on a more disaggregated basis. ASU 2010-20 was adopted in December 2010.  Our consolidated financial statements will be impacted only by additional disclosures.

111

ASU 2010-25

The FASB issued ASU 2010-25 in September 2010. The ASU 2010-25 requires participant loans to be classified as notes receivables from participants and measured at their unpaid principal balance, plus any accrued but unpaid interest.  ASU 2010-25 was adopted in December 2010, and did not impact our results of operations, financial position or liquidity, other than additional disclosures.

Research and Development

We are deeply committed to research and development as a means to extend our reach to new production frontiers and achieve continuous improvement in operations.  We have a history of successfully developing and implementing innovative technologies, including the means to drill, complete and produce wells in increasingly deep water.  We are one of the largest investors in research and development among the world’s major oil companies, and we spend a large percentage of revenues in research and development.  In 2010, we spent U.S.$993 million on research and development, equivalent to 0.8% of our net operating revenues.  In 2009, we spent U.S.$681 million on research and development, equivalent to 0.7% of our net operating revenues.  In 2008, we spent U.S.$941 million on research and development, equivalent to 0.8% of our net operating revenues.  Our Brazilian oil and gas concession agreements require us to spend at least 1% of our gross revenues originating from high productivity oil fields on research and development, of which up to half is invested in our research facilities in Brazil and the remainder is invested in research and development in Brazilian universities and institutions registered with the ANP for this purpose.

Our research and development activities focus on three main goals:

•expansion of our current businesses through the following: (a) discovery of new exploratory frontiers; (b) enhancement of oil and gas final recovery; (c) understanding and development of complex reservoirs, including pre-salt rocks; (d) development of new or enhanced subsea production systems and equipment for deep and ultra deep waters; (e) optimization of our drilling, production and logistics solutions for the pre-salt reservoirs; (f) development of new alternatives for offshore natural gas transportation; (g) optimization and reliability improvement of our industrial facilities; and (h) development and implementation of technologies in our refineries to enhance the flexibility to produce middle distillates, kerosene or gasoline, according to changing market demand;

•providing a mix of products compatible with the energy demands of the future through the following: (a) development of new fuel, lubricants and special product formulations; (b) development of new technologies for our petrochemical and gaschemical activities; (c) adaptation of our refining processes to utilize vegetable oils as feedstock; (d) development of second generation biofuel production processes, which use residual biomass as feedstock; and (e) research and development of renewable energy technologies; and

•ensuring that our activities are environmentally sustainable. We aim throughout our entire business to: (a) reduce our water consumption and the volume and toxicity of our wastewater discharges; (b) reduce our emissions of air pollutants, CO2 and other greenhouse gases; and (c) increase the energy efficiency of our processes and products.

In the three-year period ended December 31, 2010, our research and development operations were awarded 42 patents in Brazil and 120 overseas. Our portfolio of patents covers all of our areas of activities.

We have operated a dedicated research and development facility in Rio de Janeiro, Brazil since 1966.  In 2010, we concluded its expansion, doubling its laboratory capacity and placing it as the largest research complex in the southern hemisphere, with laboratories especially dedicated to pre-salt technologies.

112

We have also conducted research and development through joint research projects with more than 100 universities and other research centers in Brazil and abroad and participated in technology exchange and assistance partnerships with other oil and gas and oilfield services companies.  In 2010, we entered into agreements with several key suppliers so as to assist them in establishing technology centers in Brazil in order to develop technological solutions applicable to our business segments.

PifCo does not itself conduct research and development. 

Trends

We plan to expand all segments of operations in our target markets in accordance with our 2010-2014 Business Plan.  In support of this goal we plan total capital expenditures of U.S.$224 billion over 2010-2014.  Of this total, 53% is in the exploration and production segment, where constant investment in exploration and development is needed to exploit newly discovered resources and offset natural declines in production from existing fields as they mature.  Based on our slate of development projects, we have set a target of increasing production by 9.4% annually over the period 2010 to 2014 while replacing our reserves through organic growth.  Our business plan for 2011 through 2015 is currently under review by our board of executive officers.

The price we realize for the oil we produce is determined by international oil prices, although we generally sell our oil at a discount to the Brent and West Texas Intermediate (WTI) benchmark prices because it is heavier and thus more expensive to refine.  In 2010, international oil prices remained mostly stable between U.S.$75/bbl and U.S.$85/bbl, being largely driven by news affecting the overall expectations regarding the pace of economic recovery and the supply-demand balance in the near term.  Towards the end of 2010, oil prices gradually increased, breaking out of the U.S.$75/bbl to U.S.$85/bbl trading range.  This movement was driven by a severe winter and positive news concerning the pace of economic recovery in the United States and China.  The economic outlook will remain the key determinant of oil price movements in the near term.  A fast-paced recovery coupled with slow supply-side response can result in higher prices in the medium term.  On the other hand, if the expectations are not met, especially those regarding non-OECD economies, oil prices may drop below the current trading range.  In addition, recent geopolitical concerns may persist, affecting the global oil supply and sending oil prices higher in the near term.

For the 2010 to 2014 period, we plan to continue to focus on increasing our refining throughput and our capacity to refine heavier crudes.  During 2010, downstream gross margins varied between 4 and 11 percent reflecting the fluctuation in international prices.  Future refining margins will depend on capacity utilization in the global and Brazilian refining industries and the relative prices and volumes of light and heavy crudes that are produced and can be processed.

Under our 2010-2014 Business Plan, our net-debt-to-equity ratio is targeted to remain in the range of 25-35% through 2014, based on an estimated average exchange rate of R$1.78 per U.S.$1.00.  In accordance with the guidance provided by our board of directors on March 19, 2010, our net-debt-to-equity ratio for the 2010-2014 period is limited to 35% and our net-debt-to-EBITDA ratio to 2.5:1.

Directors and Senior Management

Directors of Petrobras

Our board of directors is composed of a minimum of five and a maximum of nine members and is responsible for, among other things, establishing our general business policies.  The members of the board of directors are elected at the annual general meeting of shareholders.

Under Brazilian Corporate Law, shareholders representing at least 10% of the company’s voting capital have the right to demand that a cumulative voting procedure be adopted to entitle each common share to as many votes as there are board members and to give each common share the right to vote cumulatively for only one candidate or to distribute its votes among several candidates.

Furthermore, our bylaws enable (i) minority preferred shareholders that together hold at least 10% of the total capital stock (excluding the controlling shareholders) to elect and remove one member to our board of directors; and (ii) minority common shareholders to elect one member to our board of directors, if a greater number of directors is not elected by such minority shareholders by means of the cumulative voting procedure.  Our bylaws provide that, regardless of the rights above granted to minority shareholders, the Brazilian federal government always has the right to elect the majority of our directors, independently of their number.  In addition, under Law 10,683, dated May 28, 2003, one of the board members elected by the Brazilian federal government must be indicated by the Minister of Planning, Budget and Management.  The maximum term for a director is one year, but re-election is permitted. In accordance with the Brazilian Corporate Law, the shareholders may remove any director from office at any time with or without cause at an extraordinary meeting of shareholders.  Following an election of board members under the cumulative vote procedure, the removal of any board member by an extraordinary meeting of shareholders will result in the removal of all the other members, after which new elections must be held.

Petrobras Audit Committee

We have an Audit Committee that advises our board of directors, composed exclusively of members of our board of directors.

On June 17, 2005, our board of directors approved the appointment of our Audit Committee to satisfy the audit committee requirements of the Sarbanes-Oxley Act of 2002 and Rule 10A-3 under the Securities Exchange Act of 1934.

The Audit Committee is responsible for, among other things:

•making recommendations to our board of directors with respect to the appointment, compensation and retention of our independent auditor;

•assisting our board of directors with analysis of our financial statements and the effectiveness of our internal controls over financial reporting in consultation with internal and independent auditors;

•assisting in the resolution of conflicts between management and the independent auditor with respect to our financial statements;

122

•conducting an annual review of related party transactions involving interested members of our board of directors and executive officers and companies that employ any of these people, as well any other material transactions with related parties; and

•establishing procedures for the receipt, retention and treatment of complaints regarding accounting, internal control and auditing matters, including procedures for the confidential, anonymous submission by employees of concerns regarding questionable accounting or auditing matters.

On December 16, 2005, our Audit Committee’s charter was amended to meet the audit committee requirements of the Sarbanes-Oxley Act of 2002 and Rule 10A-3 under the Securities Exchange Act of 1934, including the incorporation of the powers mentioned above.

The current members of our Audit Committee are Fabio Colletti Barbosa, Francisco Roberto de Albuquerque and Sergio Franklin Quintella.  All members of our Audit Committee are independent as defined in 17 CFR 240.10A-3.

Other Advisory Committees  

We implemented two additional advisory committees in 2007: the Comitê de Remuneração e Sucessão (Remuneration and Succession Committee) and the Comitê de Meio Ambiente (Environmental Committee).  In 2010, we reviewed and revised the charter of the Comitê de Remuneração e Sucessão. 

Petrobras Ombudsman  

The Petrobras General Ombudsman’s Office has been an official part of our corporate structure since October 2005, when it became directly linked to the board of directors.  The General Ombudsman’s Office is the official channel for receiving and responding to denunciations and information regarding possible irregularities in accounting, internal controls and auditing.  The General Ombudsman’s Office reports directly to the Audit Committee and guarantees the anonymity of informants. 

In December 2007, the board of directors approved the Policies and Directives of the Petrobras Ombudsman, which was an important step in aligning the General Ombudsman’s practices with those of the other ombudsmen in the system, contributing to better corporate governance.  In April 2010, the board of directors approved a two-year term, which may be renewed once, for the Ombudsman Officer so as to ensure the officer’s independence in performing his duties.

PifCo Advisory Committees  

PifCo does not have any committees of its board of directors.

Employees and Labor Relations  

We attract and retain valuable employees by offering competitive compensation and benefits, merit-based promotions and a profit-sharing plan.  In accordance with Brazilian law, total profit-sharing payments to employees are limited to 25% of the amount of proposed dividends for the year.

We increased our employee numbers in 2010 due to the growth of our business.

123

The table below shows our employee numbers for the last three years:

	As of December 31,
	2010	2009	2008
Petrobras employees:
Parent company	57,498	55,802	55,199
Subsidiaries	15,101	13,150	12,266
Abroad	7,893	7,967	6,775

Other locations	3,563	3,472	3,370
Total parent company	57,498	55,802	55,199

The table below sets forth the main expenses related to our employees for the last three years:

	2010	2009	2008
	(U.S.$ million)
Salaries	6,814.0	5,115.2	4,957.8
Employee training	207.9	132.2	232.5
Profit-sharing distributions	960.7	748.7	732.2

We have had no major labor stoppages since 1995, and we consider our relations with our employees and the unions that represent our employees to be good.  Forty-five percent of our employees are members of the Oil Workers’ National Union and 44% of our maritime employees belong to the Maritime Employees’ Union.  We negotiate collective bargaining agreements annually with both unions.  These agreements are composed of social clauses, which are valid for two years, and economic clauses, which are valid for one year.  The latest agreements were signed in 2009 (with both economic and social clauses) and in 2010 (with only economic clauses).  Under this agreement, employees received a 4.49% cost of living increase, which reflects an increase in inflation in that period, as measured by the Índice Nacional de Preços ao Consumidor Amplo (IPCA), a 9.36% increase in the minimum pay scale, and a one-time payment of 100% of monthly remuneration.

Pension and Health Care Plan

We sponsor a contributory defined benefit pension plan known as Petros, which covers 96.2% of our employees.  The principal objective of Petros has been to supplement the social security pension benefits of our employees.  Employees that participate in the plan make mandatory monthly contributions.  Our historical funding policy has been to make annual contributions to the plan in the amount determined by actuarial appraisals.  Contributions are intended to provide not only for benefits attributed to service to date but also for those expected to be earned in the future.

124

The table below shows the benefits paid, contributions made, and outstanding Petros liabilities for 2010, 2009 and 2008:

	2010	2009	2008
	(U.S.$ million)
Total benefits paid	1,054	911	932
Total contributions	460	350	286
Petros liabilities(1)	6,259	4,788	2,054

(1)           The excess of the actuarial value of our obligation to provide future benefits over the fair value of the plan assets used to satisfy that obligation.  The increase in these liabilities in 2010 was primarily due to the change of the discount rate from 6.6% per year in 2009 to 5.9% per year in 2010.  See Note 15.6 to our audited consolidated financial statements for the year ended December 31, 2010.

On August 9, 2002, the Petros Plan stopped admitting new participants and since 2003 we have been engaged in complex negotiations with representatives of the Oil Worker’s National Union to address the deficits of the plan and develop a supplementary pension plan.  We have also been subject to material legal proceedings in connection with the Petros Plan.  In August 2007, we approved new regulations for the Petros Plan and entered into an agreement with the Oil Worker’s National Union and other parties involved which will extinguish the existing lawsuits in connection with the Petros Plan.  The main changes introduced to the Petros Plan include: (i) salary increases of active employees will no longer be passed to retired employees, (ii) the benefits of participants of the plan will be adjusted according to the IPCA inflation index, and (iii) decreases in pensions provided by the government plan will not be supplemented by the Petros Plan.  We agreed to pay R$5.8 billion updated retroactively to December 31, 2006 by the consumer price index (IPCA) plus 6% per year, which will be paid in semi-annual installments with interest of 6% per year on the balance for the next 20 years, as previously agreed during the renegotiation.

On July 1, 2007, we implemented the Petros Plan 2, a variable contribution or mixed pension plan, for employees with no supplementary pension plan.  A portion of this plan with defined benefits characteristics includes risk coverage for disability and death, a guaranty of a minimum benefit and a lifetime income, and the related actuarial commitments are recorded according to the projected credit unit method.  The portion of the plan with defined contribution characteristics, earmarked for forming a reserve for programmed retirement, is recognized in the results for the year as the contributions are made.  In 2010, the contribution of Petrobras and its subsidiaries to the defined contribution portion of this plan was U.S.$460 million.  The expenses and benefit obligations related to Petros Plan 2 were recorded according to ASC 715 Compensation – Retirement Benefits.

We maintain a health care benefit plan (AMS), which offers health benefits and covers all employees (active and inactive) together with their dependents.  We manage the plan, with the employees contributing fixed amounts to cover principal risks and a portion of the costs relating to other types of coverage in accordance with participation tables defined by certain parameters, including salary levels.

Our commitment related to future benefits to plan participants is calculated on an annual basis by an independent actuary, based on the Projected Unit Credit method.  The health care plan is not funded or otherwise collateralized by assets.  Instead, we make benefit payments based on annual costs incurred by plan participants.

In addition, some of our consolidated subsidiaries have their own benefit plans.

PifCo

With the exception of 55 employees of PEL and 51 employees of PSPL, PifCo’s personnel consist solely of our employees, and PifCo relies on us to provide all administrative functions.  In May 2008, PifCo and Petrobras entered into an agreement to share costs and expenditures related to PifCo’s use of Petrobras’ administrative resources.

As a result of being our wholly owned subsidiary, PifCo has numerous transactions with us and other affiliated companies in the ordinary course of business.  Prior to April 2010, PifCo engaged in crude oil and oil product purchases from international suppliers and resold crude oil and oil products in U.S. dollars to us on a deferred payment basis, at a price which represented a premium to compensate PifCo for its financing costs.  In April 2010, PifCo began selling crude oil and oil products to us under terms that allow payment in up to approximately 30 days, without a premium.  PifCo also purchases crude oil and oil products from us to hold in inventory and for sale outside Brazil.  Substantially all of PifCo’s revenues are generated by transactions with us.  Additionally, PifCo sells and purchases crude oil and oil products to and from third parties and related parties, mainly outside Brazil.

Since PifCo’s inception there have been no, and there are no proposed, material transactions with any of PifCo’s officers and directors.  PifCo does not extend any loans to its officers and directors.

PifCo’s transactions with related parties resulted in the following balances in 2010 and 2009:

Legal Proceedings  

Petrobras

We are currently subject to numerous proceedings relating to civil, criminal, administrative, environmental, labor and tax claims.  Several individual disputes described in further detail below account for a significant part of the total amount of claims against us.  Our audited consolidated financial statements only include provisions for probable and reasonably estimable losses and expenses we may incur in connection with pending proceedings.  See Note 18 to our audited consolidated financial statements.  The table below sets forth our recorded financial provisions by type of claim:⁽¹⁾ 

	Provisions as of December 31,
	2010	2009
	(U.S.$ million)
Labor claims	119	71
Tax claims	361	94
Civil claims	214	272
Commercial claims and other contingencies	66	63
Total	760	500

(1)                  Excludes provisions for contractual contingencies and tax assessments by the Instituto Nacional do Seguro Social, or INSS.

The amount accrued related to claims against Petrobras, the parent company, as of December 31, 2010, corresponded to approximately 33.5% of the total amount accrued by us related to claims against us and the amounts paid by us in respect of legal claims against Petrobras in the last five years averaged U.S.$386 million per year.  As of December 31, 2010, we estimate that the total amount of claims against us, excluding disputes involving non-monetary claims or claims not easily evaluated in the current stage of the proceedings, was approximately U.S.$38.7 billion. 

The most significant claims against us are summarized below:

Civil Claims

On November 23, 1992, Porto Seguro Imóveis Ltda., a minority shareholder of Petroquisa, filed a lawsuit on behalf of Petroquisa (a shareholder derivative suit) against us for alleged losses suffered as a result of the sale of Petroquisa’s interest in various petrochemical companies included in the National Privatization Program (Programa Nacional de Desestatização).  The plaintiff in the lawsuit requests that we, as controlling shareholder of Petroquisa, be compelled to reinstate the damages made to Petroquisa’s equity, since we approved the minimum sales price for the privatized companies.  An initial decision on January 14, 1997, held us liable to Petroquisa for damages in an amount equivalent to U.S.$3,406 million.  In addition, we were required to pay the plaintiff 5% of such amount as a premium, as well as attorney’s fees of 20% of such amount.  In 2006, we purchased all of the minority interests of Petroquisa, and we now own 100.0% of its share capital.  We appealed and prevailed in canceling the judgment, but a subsequent appellate decision on March 30, 2004, required Petrobras to indemnify Petroquisa and Porto Seguro for U.S.$2,359 million and U.S.$590 million, respectively (the latter representing 5% in premium and 20% in attorney’s fees).  There are ongoing proceedings in the STJ and in the STF, which are scheduled to be finalized in 2011 seeking to reverse the award.

If this award is not reversed, the indemnity estimated to Petroquisa, including monetary corrections and interest, would be U.S.$11,422 million.  However, because Petrobras owns 100% of Petroquisa’s share capital, a portion of the indemnity estimated at U.S.$7,539 million will not require a disbursement by us.  We will also be required to pay U.S.$571 million to Porto Seguro and U.S.$2,284 million in attorney’s fees if the award is not reversed.  For more information on this claim, see Note 18(b) to our audited consolidated financial statements as of December 31, 2010.

In 1981, Kallium Mineração S.A. brought an action against Companhia de Pesquisa de Recursos Minerais—CPRM seeking an indemnification of approximately U.S.$450 million for the early termination of a contract for the exploration of a very large potassium salt mine in Sergipe.  CPRM terminated the contract when the Brazilian federal government, which had previously granted CPRM the right to develop an exploration project for the mine, cancelled the concession to CPRM and transferred it to Petromisa, our former subsidiary.  As a result, CPRM brought us and the Brazilian federal government into the proceedings as co-defendants.  In 1999, despite denying most of Kallium’s claims, the court required us to indemnify Kallium for their research and exploration costs, which correspond to approximately U.S.$1 million.  We and Kallium have appealed the decision and are awaiting a judgment.  The total damages amount that may be payable will be subject to monetary adjustment and to interest at 6% calculated as of the date of the filing of the lawsuit.  As of December 31, 2010, Petrobras’ maximum exposure in this matter, including monetary restatement, was R$196 million (U.S.$117 million).

Several individuals have filed a collective lawsuit (an ação popular) against us, Repsol-YPF and the Brazilian federal government seeking to unwind the 2001 exchange of certain of our operating assets in Brazil for some of YPF’s operating assets in Argentina.  The plaintiffs maintain that the assets exchanged were not properly valued and that, therefore, the transaction was not in our best interests.  In 2002, the court granted an injunction to the plaintiffs, which was then suspended by the Superior Court of Justice of Brazil.  The lawsuit was subsequently judged on the merits in our favor and the other parties appealed.  We are awaiting a final decision on the merits.

On January 18, 2000, a pipeline connecting one of our terminals to a refinery in Guanabara Bay ruptured, causing a release of approximately 341,000 gallons of crude oil into the bay.  We undertook action to control the spill in an effort to prevent the oil from threatening additional areas.  As a result of this spill, several individual damage lawsuits were filed by fishermen of the State of Rio de Janeiro, in an aggregate amount of approximately R$52 million.  In addition, the Federation of Fishermen of the State of Rio de Janeiro filed a lawsuit against us claiming damages of approximately R$537 million.  In 2002, the judge hearing this matter found that damages were due, but not in the amount claimed.  Both parties appealed this decision, and later in 2002, the Court of Appeals of the State of Rio de Janeiro denied the appeal filed by the plaintiff and dismissed numerous claims, including those of all fishermen who had already settled their claims against us, those who had already filed individual lawsuits against us, and certain others.  Further appeals (agravos de instrumento) by both sides presented in 2003, to the STJ and the STF, respectively, were denied.  On February 2, 2007, the judge who initially heard the case published a decision overturning the appellate court’s decision and partially accepting the court expert report that defined the period over which Guanabara Bay’s fish would be affected by the spill.  Given that the amount of damages for each fisherman affected is the same, this decision resulted in an aggregate amount of damages equal to R$1,102 million through December 2005 (without interest and monetary indexation after that date).  We appealed this decision and our appeal was denied in July 2007.  An appeal filed by the Federation of Fishermen of the State of Rio de Janeiro was granted and, as a result, the number of fishermen entitled to damages increased from 12,000 to 20,000.  We have appealed both of these decisions to the STJ.  In November 2009, the STJ granted our appeal to annul the decision from the judge who initially heard the case.  In November 2010, the case was returned to the Tribunal de Justiça do Rio de Janeiro for another judgment.  For more information on this claim, see Note 18(b) to our audited consolidated financial statements as of December 31, 2010.

For information on the legal proceeding related to our interest in the Pasadena Refining System and its trading company, see Item 4. “International—Other International Activities—North America."

Tax Claims

In June 2003, the State of Rio de Janeiro enacted a new tax law that imposed ICMS on our production activities.  The State of Rio de Janeiro has never enforced this law, and its constitutionality is being challenged in the STF.  In the event that the state government attempts to enforce this law and the courts uphold that enforcement, we estimate that the amount of ICMS that we would be required to pay to the State of Rio de Janeiro could increase by approximately R$10.9 billion (U.S.$6.2 billion) per year.

In July 2005, the São Paulo state revenue service filed a tax assessment against us arguing that we should have paid ICMS tax on imports of natural gas from Bolívia. The lower administrative court upheld the tax assessment, and we filed an appeal of this administrative ruling that was rejected. We await the registration of the alleged outstanding amount of the tax assessment by the São Paulo state revenue service. We will then evaluate whether we will challenge the tax assessment in court and obtain an injunction to suspend the collection of the tax assessment until a final judicial ruling has been made. The maximum exposure for us relating to this tax assessment as of December 31, 2010, including monetary restatement, was R$1,025 million (U.S.$615 million). Based on the advice of our legal counsel, we have assessed the risk of loss to be possible.

In March 2009, the Rio de Janeiro revenue service filed two tax assessments against us arguing that we should have paid ICMS tax on LNG intercompany transfers. We filed appeals for both tax assessments in the administrative Taxpayers Council, and both appeals were rejected. We successfully obtained an injunction from the competent court to suspend our obligation to pay the ICMS tax assessments until a final judicial ruling has been made on the matter. The Rio de Janeiro state revenue service is now challenging our injunction. The maximum exposure for us for both tax assessments as of December 31, 2010, including monetary restatement, was R$2,088 million (U.S.$1,253 million). Based on the advice of our legal counsel, we have assessed the risk of loss to be possible.

In August 2009, the São Paulo revenue service filed two tax assessments against us alleging that (i) we should have not ceased to collect ICMS tax on the importation of a drilling rig, and (ii) that we did not comply with an accessory tax obligation. The lower administrative court upheld both tax assessments, and we filed an appeal on December 23, 2009. A judicial decision was rendered in our favor suspending our obligation to pay the ICMS tax component of the assessment, and we await a final administrative decision with respect to the alleged non-compliance with an accessory tax obligation. The maximum exposure for us with respect to the alleged non-compliance with an accessory tax obligation as of December 31, 2010, including monetary restatement, was R$1,734 million (U.S.$1,041 million). Based on the advice of our legal counsel, we have assessed the risk of loss to be possible.

On July 18, 2007, we were notified of a new ANP board resolution requiring payment of additional government participation charges retroactively to 1998.  This resolution, which annulled an earlier board resolution, determined that we should make an additional payment in the amount of approximately R$400 million (U.S.$230 million) for special government participation charges from the Marlim field.  In 2007, we filed suit to challenge the new method used by the ANP to calculate the special participation tax.  The lower court decided in favor of the ANP, and this decision was upheld by a regional federal court on September 30, 2009.  Petrobras subsequently appealed this decision to higher courts in Brasilia.  On October 23, 2009, we, the ANP and the State of Rio de Janeiro reached an agreement to resolve the dispute out of court.  The amount owed to the ANP for retroactive special participation from the Marlim field was fixed at R$2,065 million (U.S.$1,034 million) as of September 30, 2009, payable in eight consecutive monthly installments and adjusted by the benchmark SELIC rate.  We have paid the remaining installments related to this settlement in 2010, definitively resolving any and all legal and administrative actions relating to this matter.

In January 2004, the municipalities of Anchieta, Aracruz, Guarapari, Itapemirim, Jaguaré, Marataízes, Serra, Vila Velha and Vitória, all of which are located in the State of Espírito Santo, filed tax assessments against us with administrative courts for our alleged failure to withhold service taxes (ISS tax assessments) on services provided to our offshore platforms. We withheld and paid the ISS taxes to the municipalities where the respective service providers are headquartered, in accordance with Complementary Law 116/03. In the tax assessments, we presented various administrative defenses with the aim of annulling the tax assessments, which defenses are currently being considered by the administrative courts, and we posted an insurance-backed guarantee of payment that has been accepted by the courts. The one proceeding that has been filed at the judicial level is a tax collection proceeding by the municipality of Itapemirim, for which we also posted an insurance-backed guarantee of payment. We are contesting this proceeding on the basis that we have paid the taxes in accordance with Complementary Law 116/03. The maximum exposure for us as of December 31, 2010, including monetary restatement, in the aggregate in connection with these tax assessments was R$1,446 million (U.S.$868 million). Based on the advice of our legal counsel, we have assessed the risk of loss to be possible.

We have been served with assessments by the Brazilian Revenue Service relating to a withholding tax (IRRF) that they claim should have been paid by us.  The assessments relate to payments we made to purchase oil we imported and to charter payments we made with respect to movable platform vessels.  On May 8, 2008, we filed suit concerning one of the tax assessments related to charter payments, and the court granted preliminary injunctive relief (tutela antecipada) suspending the withholding tax until a final judgment was reached. In February 2010, the court issued a final decision against the Brazilian Revenue Service, cancelling the tax assessment. The Brazilian Revenue Service is appealing the decision. On December 31, 2010, the total amount of these tax assessments corresponded to approximately R$5,419 million (approximately U.S.$3,252 million).  We have contested the assessment related to payments we made to purchase oil we imported, which is pending appeal at the administrative level. With respect to the assessment related to charter payments, our appeal at the administrative level has been denied and we plan to bring suit at the federal judicial level.

We sold imported naphtha for the production of petrochemical raw materials, as opposed to the production of gasoline or diesel.  In 2006, the Brazilian Revenue Service filed a tax assessment (auto de infração) against us for the payment of CIDE, an excise tax applied to the sale and import of crude oil, oil products and natural gas products, on the grounds that we did not prove that the naphtha was not used to produce gasoline or diesel.  As we have provided evidence that the naphtha was used solely in petrochemical activities, we believe these imports are not taxable.  The assessment is being reviewed, and we will continue to appeal at the federal administrative level and later at the federal judicial level, if necessary.  As of December 31, 2010, Petrobras’ maximum exposure in this matter, including monetary restatement, was R$2,196 million (U.S.$1,318 million).

Petrobras was obligated to sell its products to fuel distributors free of CIDE (an excise tax) due to judicial decisions obtained by the distributors against the federal government of Brazil.  The judicial decisions have been revoked, and in 2007, the Brazilian federal government commenced an administrative proceeding against us to recover unpaid CIDE.  We filed an appeal at the administrative level in light of the first unfavorable administrative decision.  As of December 31, 2010, Petrobras’ maximum exposure in this matter, including monetary restatement, was R$1.189 million (U.S.$714 million).

Environmental Claims

In the period between 2006 to 2010, we experienced several accidents which led to the following volumes of oil spilled each year: 176,388 gallons in 2010, 67,102 gallons in 2009, 115,179 gallons in 2008, 101,970 gallons in 2007 and 77,402 gallons in 2006.  In addition, in the years 2000 through 2002, we experienced accidents that resulted in several administrative, civil and criminal investigations and proceedings, some of which have not yet been concluded, and the most significant of which are specified below.  We cannot predict whether additional litigation will result from those accidents or whether any such additional proceedings would have a material adverse effect on us.  See Note 18(b) to our audited consolidated financial statements.

January 2000 spill—Guanabara Bay

On January 18, 2000, a pipeline connecting one of our terminals to a refinery in Guanabara Bay ruptured, causing a release of approximately 341,000 gallons of fuel oil into the bay.  We undertook action to control the spill in an effort to prevent the oil from threatening additional areas.  We have spent approximately R$104 million (U.S.$59 million) in connection with the clean-up efforts and fines imposed by the federal environmental protection agency (IBAMA) in connection with this spill, and are subject to several legal proceedings that remain pending as a result of this spill.

133

July 2000 spill—Curitiba

On July 16, 2000, the Santa-Catarina/Paraná pipeline ruptured at our President Getúlio Vargas refinery, located approximately 15 miles (24 kilometers) from Curitiba, capital of the State of Paraná.  Approximately 1.06 million gallons of crude oil spilled into the surrounding area.  We spent approximately R$74 million (U.S.$42 million) at the time on the clean-up effort and fines imposed by the State of Paraná authorities.  In addition, in relation to this spill:

•IBAMA fined us R$168 million (U.S.$101 million), which we are contesting on the basis that we are being fined for the same infraction twice;

•three public civil actions (ações civis públicas) have been filed against us, the most important of which was filed on January 1, 2001, by the Federal Public Prosecutor and the Paraná State Public Prosecutor seeking damages of approximately R$2,300 million (U.S.$1,437million).  Currently, this suit is awaiting the results of an expert examination (prova pericial); and

•the Federal Public Ministry instituted a criminal action against us, our former chief executive officer and the former superintendent of the REPAR refinery.  This action has been dismissed with respect to our former chief executive officer and suspended, pending a decision on a petition for reconsideration filed by the Federal Public Ministry, with respect to us and the former superintendent of the REPAR refinery.

February 2001 spill—Rivers in the State of Paraná

On February 16, 2001, our Araucária-Paranaguá pipeline ruptured as a result of an unusual movement of the soil and spilled approximately 15,059 gallons of fuel oil into several rivers located in the State of Paraná.  Within four days, we cleaned the river surfaces, recovering approximately 13,738 gallons of fuel oil.  As a result of the accident:

•the Instituto Ambiental do Paraná, or IAP, fined us R$150 million (U.S.$90 million), which was subsequently reduced to R$90 million (U.S.$54 million), which we are contesting on the basis that the IAP has failed to respond to our proposed remedy within the three-year period specified under such proposal; and

•the Federal Public Ministry and the Paraná State Public Ministry filed class actions against us seeking approximately R$3,100 million (U.S.$1,937 million) in damages.  In addition, the IAP filed a class action against us seeking environmental damages of approximately R$150 million (U.S.$90 million).  These actions have been joined before the Federal Public Ministry in Paranaguá (Vara Federal de Paranaguá), and await a final decision.

March 2001 gas explosion and spill—Roncador field

On March 15, 2001, a gas explosion inside one of the columns of the P-36  production platform, located in the Roncador field (75 miles off the Brazilian coast) led to the death of 11 employees and eventual sinking of the platform.  The accident also caused 396,300 gallons of diesel fuel and oil to spill into the ocean.  As a result of the accident:

•the Federal Public Ministry filed a lawsuit in 2002 seeking the payment of R$100 million as environmental damages, among other demands.  We have presented our defense to these claims and are awaiting a decision; and

•IBAMA fined us approximately R$7 million.  We have challenged these fines through administrative proceedings, which fines were upheld by IBAMA.  We filed suit (ação anulatória) to annul both administrative proceedings.

134

October 2002 FPSO accident

On October 13, 2002, a power blackout in FPSO P-34, which is located in the Barracuda-Caratinga fields, affected the ship’s water balance system and causing the FPSO to roll.  Four days later, the stability of the ship had been restored, without casualties or spill of oil into the sea.  As a result of the investigation of this accident, several measures to prevent similar accidents were incorporated into our Programa de Excelência Operacional, or PEO (Operational Excellence Program).  In connection with the accident, we also executed a Termo de Ajustamento de Conduta (Agreement for Regularization of Conduct), or TAC, with IBAMA, agreeing to conduct certain actions in the Campos Basin to reduce the risk of environmental damage.  The Federal Public Ministry challenged the validity of the TAC in 2003 and attempted to prevent us from obtaining new licenses from IBAMA for our platforms located in the Campos Basin.  We obtained a favorable court decision, which was appealed by the Federal Public Ministry.  The Court decided the appeal partially in favor of the Federal Public Ministry.  In 2010, the Court upheld its decision to invalidate and strike out clause 10 of the TAC.  This clause establishes that during the term of the TAC, the Federal Public Ministry cannot impose any administrative sanctions on us relating to the purpose of the TAC.  The other clauses of the TAC remain valid and in full force and effect.

Campos BasinDrilling Operations

On February 3, 2006, IBAMA imposed a fine on us for our alleged breach of the August 11, 2004 TAC with IBAMA relating to drilling operations in the Campos Basin, in an adjusted amount of R$122.9 million (U.S.$74 million).  On December 1, 2010, we submitted a declaratory action contesting the validity of the fine imposed on us pursuant to an alleged breach of clause 3 of the TAC.

Pollution

On January 15, 1986, the Public Ministry of the State of São Paulo and the União dos Defensores da Terra (Union for Defense of the Earth), filed a public civil action against us and 23 other companies in the State Court of São Paulo for alleged damages caused by pollution.  The amount alleged in the initial pleading filed with the Court is equivalent to R$4,217 (U.S.$2,531), but it is difficult to estimate the actual damages that could be assessed by the Court.  The Public Ministry of the State of São Paulo has publicly stated that the amount of U.S.$800 million would ultimately be required to remedy the alleged environmental damage.  The Court has asserted the joint liability of the defendants and the discovery phase has yet to begin.

BM&FBOVESPA

The BM&FBOVESPA is less liquid than the New York Stock Exchange.  At December 31, 2010, the aggregate market capitalization of the 381 companies listed on the BM&FBOVESPA was approximately U.S.$1,542 billion and the ten largest companies represented approximately 55.45% of the total market capitalization of all listed companies.  All the outstanding shares of an exchange-listed company may trade on the BM&FBOVESPA, but in most cases, less than half of the listed shares are actually available for trading by the public.  The remainder is held by small groups of controlling persons, by governmental entities or by one principal shareholder.

Trading on the BM&FBOVESPA by a holder not deemed to be a resident of Brazil for Brazilian tax and regulatory purposes (a non-Brazilian holder) is subject to certain limitations under Brazilian foreign investment legislation.  With limited exceptions, non-Brazilian holders may only trade on the BM&FBOVESPA in accordance with the requirements of Resolution No. 2,689 of the CMN.  Resolution No. 2,689 requires that securities held by non-Brazilian holders be maintained in the custody of, or in deposit accounts with, financial institutions duly authorized by the Central Bank of Brazil and the CVM.  In addition, Resolution No. 2,689 requires non-Brazilian holders to restrict their securities trading to transactions on Brazilian stock exchanges or qualified over-the-counter markets.  With limited exceptions, non-Brazilian holders may not transfer the ownership of investments made under Resolution No. 2,689 to other non-Brazilian holders through a private transaction.

Item 10.                Additional Information

Memorandum and Articles of Incorporation of Petrobras  

General

We are a publicly traded company duly registered with the CVM under identification number 951-2.  Article 3 of our bylaws establishes our corporate purposes as research, prospecting, extraction, processing, trade and transportation of crude oil from wells, shale and other rocks, of its derivatives, natural gas and other fluid hydrocarbons, as well as other related or similar activities, such as activities connected with energy, including research, development, production, transportation, distribution, sale and trade of all forms of energy, as well as other related or similar activities.  We may conduct outside Brazil, directly or through our subsidiaries, any of the activities within our corporate purpose.

Qualification of Directors

Brazilian law provides that only shareholders of a company may be appointed to its board of directors, but there is no minimum share ownership or residency requirement for qualification as a director.  Members of our board of executive officers must be Brazilian nationals and reside in Brazil.  In addition, Law No. 12,353, enacted on December 28, 2010, requires that public and mixed-capital companies in which the Brazilian federal government holds directly or indirectly a majority of the voting rights include as an additional director in their board of directors a representative elected by the company’s employees.  Our directors and executive officers are prevented from voting on any transaction involving companies in which they hold more than 10% of the total capital stock or of which they have held a management position in the period immediately prior to their taking office.  Under our bylaws, shareholders set the aggregate compensation payable to directors and executive officers.  The board of directors allocates the compensation among its members and the executive officers.

Allocation of Net Income

At each annual general shareholders’ meeting, our board of directors is required to recommend how net profits for the preceding fiscal year are to be allocated.  The Brazilian Corporate Law defines net profits as net income after income taxes and social contribution taxes for such fiscal year, net of any accumulated losses from prior fiscal years and any amounts allocated to employees’ and management’s participation in our profits.  In accordance with the Brazilian Corporate Law, the amounts available for dividend distribution or payment of interest on shareholders’ equity equals net profits less any amounts allocated from such net profits to the legal reserve.

We are required to maintain a legal reserve, to which we must allocate 5% of net profits for each fiscal year until the amount for such reserve equals 20% of our paid-in capital.  However, we are not required to make any allocations to our legal reserve in a fiscal year in which the legal reserve, when added to our other established capital reserves, exceeds 30% of our capital.  The legal reserve can only be used to offset losses or to increase our capital.

As long as we are able to make the minimum mandatory distribution described below, we must allocate an amount equivalent to 0.5% of subscribed and fully paid-in capital at year-end to a statutory reserve.  The reserve is used to fund the costs of research and technological development programs.  The accumulated balance of this reserve cannot exceed 5% of the subscribed and fully paid-in capital stock.

138

Brazilian law also provides for three discretionary allocations of net profits that are subject to approval by the shareholders at the annual general shareholders’ meeting, as follows:

•first, a percentage of net profits may be allocated to a contingency reserve for anticipated losses that are deemed probable in future years.  Any amount so allocated in a prior year must be either reversed in the fiscal year in which the reasons justifying the reserve cease to exist, or written off in the event that the anticipated loss occurs;

•second, if the mandatory distributable amount exceeds the sum of realized net profits in a given year, this excess may be allocated to an unrealized revenue reserve.  The Brazilian Corporate Law defines realized net profits as the amount of net profits that exceeds the sum of the net positive result of equity adjustments and profits or revenues from operations whose financial results take place after the end of the next succeeding fiscal year; and

•third, a portion of our net profits that exceeds the minimum mandatory distribution may be allocated to fund working capital needs and investment projects, as long as such allocation is based on a capital budget previously approved by our shareholders.  Capital budgets for more than one year must be reviewed at each annual shareholders’ meeting.

Mandatory Distribution

Under Brazilian Corporate Law, the bylaws of a Brazilian corporation with a class of non-voting shares, such as ours, may specify a minimum percentage of the amounts available for distribution by such corporation for each fiscal year that must be distributed to shareholders as dividends or interest on shareholders’ equity, also known as the mandatory distributable amount, which cannot be lower than 25% of the adjusted net profit for the fiscal year.  Under our bylaws, the mandatory distributable amount has been fixed at an amount equal to not less than 25% of our net profits, after the allocations to the legal reserve, contingency reserve and unrealized revenue reserve.  Furthermore, the net profits that are not allocated to the reserves above to fund working capital needs and investment projects as described above or to the statutory reserve must be distributed to our shareholders as dividends or interest on shareholders’ equity.

The Brazilian Corporate Law, however, permits a publicly held company, such as ours, to suspend the mandatory distribution if the board of directors and the Fiscal Council report to the annual general shareholders’ meeting that the distribution would be inadvisable in view of the company’s financial condition.  The suspension is subject to approval of holders of common shares. In this case, the board of directors must file a justification for such suspension with the CVM.  Profits not distributed by virtue of the suspension mentioned above shall be allocated to a special reserve and, if not absorbed by subsequent losses, shall be distributed as soon as the financial condition of the company permits such payments.

Payment of Dividends and Interest on Shareholders’ Equity

We are required by the Brazilian Corporate Law and by our bylaws to hold an annual general shareholders’ meeting by the fourth month after the end of each fiscal year at which, among other things, the shareholders have to decide on the payment of an annual dividend.  The payment of annual dividends is based on the financial statements prepared for the relevant fiscal year.

Law No. 9,249 of December 26, 1995, as amended, provides for distribution of interest attributed to shareholders’ equity to shareholders as an alternative form of distribution.  Such interest is limited to the daily pro rata variation of the TJLP interest rate, the Brazilian federal government’s long-term interest rate.

139

We may treat these payments as a deductible expense for corporate income tax and social contribution purposes, but the deduction cannot exceed the greater of:

•50% of net income (before taking into account such distribution and any deductions for income taxes and after taking into account any deductions for social contributions on net profits) for the period in respect of which the payment is made; or

•50% of retained earnings.

Any payment of interest on shareholders’ equity to holders of ADSs or common shares, whether or not they are Brazilian residents, is subject to Brazilian withholding tax at the rate of 15% or 25%.  The 25% rate applies if the beneficiary is resident in a tax haven.  See “—Taxation Relating to Our ADSs and Common and Preferred Shares—Brazilian Tax Considerations.”  The amount paid to shareholders as interest attributed to shareholders’ equity, net of any withholding tax, may be included as part of any mandatory distribution of dividends.  Under the Brazilian Corporate Law, we are required to distribute to shareholders an amount sufficient to ensure that the net amount received, after payment by us of applicable Brazilian withholding taxes in respect of the distribution of interest on shareholders’ equity, is at least equal to the mandatory dividend.

Under the Brazilian Corporate Law and our bylaws, dividends generally are required to be paid within 60 days following the date the dividend was declared, unless a shareholders’ resolution sets forth another date of payment, which, in either case, must occur prior to the end of the fiscal year in which the dividend was declared.  The amounts of dividends due to our shareholders are subject to financial charges at the SELIC rate from the end of each fiscal year through the date we actually pay such dividends.  Shareholders have a three-year period from the dividend payment date to claim dividends or interest payments with respect to their shares, after which the amount of the unclaimed dividends reverts to us.

Pursuant to our bylaws, holders of preferred shares are entitled to minimum annual dividends equal to (i) 5% of their pro rata share of our paid-in capital, or (ii) 3% of the book value of their preferred shares, whichever is higher.  Holders of preferred shares participate equally with common shareholders in corporate capital increases obtained from the incorporation of reserves and profits.  To the extent that we declare dividends in any particular year in an amount that exceeds the minimum preferential dividends on preferred shares, holders of common shares and preferred shares will receive the same additional dividend amount per share.  Based on our equity capital at year-end 2010, the minimum preferential dividend that would have been payable to our preferred shareholders is approximately R$0.77 per preferred share (R$1.54 per preferred ADS), compared to the R$1.03per preferred share (R$2.06per preferred ADS) actually paid on our 2010 earnings.  Since 2000, our distributable income has always exceeded the minimum preferred dividend, so we have always distributed equal amounts to both our common and preferred shareholders during this period.

Our board of directors may distribute dividends or pay interest based on the profits reported in interim financial statements.  The amount of interim dividends distributed cannot exceed the amount of our capital reserves.

Shareholders’ Meetings

Our shareholders have the power to decide on any matters related to our corporate purposes and to pass any resolutions they deem necessary for our protection and development, through voting at a general shareholders’ meeting.

We convene our shareholders’ meetings by publishing a notice in the Diário Oficial da União and Jornal do Commercio.  The notice must be published no fewer than three times, beginning at least 15 calendar days prior to the scheduled meeting date.  The notice must contain the meeting’s agenda and, in the case of a proposed amendment to the bylaws, an indication of the subject matter.  For ADS holders, we are required to provide notice to the ADS depositary at least 30 calendar days prior to a shareholders’ meeting.

140

The board of directors or, in some specific situations set forth in the Brazilian Corporate Law, the shareholders, call our general shareholders’ meetings.  A shareholder may be represented at a general shareholders’ meeting by an attorney-in-fact, so long as the attorney-in-fact was appointed within a year of the meeting.  The attorney-in-fact must be a shareholder, a member of our management, a lawyer or a financial institution.  The attorney-in-fact’s power of attorney must comply with certain formalities set forth by Brazilian law.

In order for a valid action to be taken at a shareholders’ meeting, shareholders representing at least one quarter of our issued and outstanding common shares must be present at the meeting.  However, in the case of a general meeting to amend our bylaws, shareholders representing at least two-thirds of our issued and outstanding common shares must participate in person.  If no such quorum is present, the board may call a second meeting giving at least eight calendar days notice prior to the scheduled meeting in accordance with the rules of publication described above.  The quorum requirements will not apply to the second meeting, subject to the voting requirements for certain matters described below.  Beginning in 2010, our shareholders may also register online to exercise their voting rights electronically in shareholders’ meetings.  In addition, our shareholders may also vote electronically in proxy contests (pedido público de procuração).  Electronic participation in shareholders’ meetings is not available to our ADR holders.

Voting Rights

Pursuant to the Brazilian Corporate Law and our bylaws, each of our common shares carries the right to vote at a general meeting of shareholders.  The Brazilian federal government is required by law to own at least a majority of our voting stock.  Pursuant to our bylaws, our preferred shares generally do not confer voting rights.

Holders of common shares, voting at a general shareholders’ meeting, have the exclusive power to:

•amend our bylaws;

•approve any capital increase;

•approve any capital reduction;

•elect or dismiss members of our board of directors and Fiscal Council, subject to the right of our preferred shareholders to elect or dismiss one member of our board of directors and to elect one member of our Fiscal Council;

•receive the yearly financial statements prepared by our management and accept or reject management’s financial statements, including the allocation of net profits for payment of the mandatory dividend and allocation to the various reserve accounts;

•authorize the issuance of debentures, except for the issuance of non-convertible unsecured debentures, which may be approved by our board of directors;

•suspend the rights of a shareholder who has not fulfilled the obligations imposed by law or by our bylaws;

•accept or reject the valuation of assets contributed by a shareholder in consideration for issuance of capital stock;

•pass resolutions to approve corporate restructurings, such as mergers, spin-offs and transformation into another type of company;

•participate in a centralized group of companies;

141

•approve the disposal of the control of our subsidiaries;

•approve the disposal of convertible debentures issued by our subsidiaries and held by us;

•establish the compensation of our senior management;

•approve the cancellation of our registration as a publicly-traded company;

•decide on our dissolution or liquidation;

•waive the right to subscribe to shares or convertible debentures issued by our subsidiaries or affiliates; and

•choose a specialized company to work out the appraisal of our shares by economic value, in cases of the canceling of our registry as a publicly-traded company or deviation from the standard rules of corporate governance defined by a stock exchange or an entity in charge of maintaining an organized over-the-counter market registered with the CVM, in order to comply with such corporate governance rules and with contracts that may be executed by us and such entities.

Except as otherwise provided by law, resolutions of a general shareholders’ meeting are passed by the majority of the outstanding common shares.  Abstentions are not taken into account.

The approval of holders of at least one-half of the issued and outstanding common shares is required for the following actions involving our company:

•reduction of the mandatory dividend distribution;

•merger into another company or consolidation with another company, subject to the conditions set forth in the Brazilian Corporate Law;

•participation in a group of companies subject to the conditions set forth in the Brazilian Corporate Law;

•change of our corporate purpose, which must be preceded by an amendment in our bylaws by federal law as we are controlled by the government and our corporate purpose is established by law;

•cessation of the state of liquidation;

•spin-off of a portion of our company, subject to the conditions set forth in the Brazilian Corporate Law;

•transfer of all our shares to another company or receipt of shares of another company in order to make the company whose shares are transferred a wholly owned subsidiary of such company, known as incorporação de ações; and

•approval of our liquidation.

Under Brazilian Corporate law, if shareholder has a conflict of interest with the company in connection with any proposed transaction, the shareholder may not vote in any decision regarding such transaction.  For example, an interested shareholder may not vote to approve the valuation of assets contributed by that shareholder in exchange for capital stock or, when the shareholder is a member of senior management, to approve the management’s report on the company’s financial statements.  Any transaction approved with the vote of a shareholder with a conflict of interest may be annulled and such shareholder may be liable for any damages caused and be required to return to the company any gain it may have obtained as a result of the transaction.

142

According to the Brazilian Corporate Law, the following actions shall be submitted for approval by the outstanding adversely affected preferred shares before they are submitted for approval of at least half of the issued and outstanding common shares:

•creation of preferred shares or increase in the existing classes of preferred shares, without preserving the proportions to any other class of preferred shares, except as set forth in or authorized by the company’s bylaws;

•change in the preferences, privileges or redemption or amortization conditions of any class of preferred shares; and

•creation of a new class of preferred shares entitled to more favorable conditions than the existing classes.

Decisions on our transformation into another type of company require the unanimous approval of our shareholders, including the preferred shareholders, and an amendment of our bylaws by the federal law.

Our preferred shares will acquire voting rights if we fail to pay the minimum dividend to which such shares are entitled for three consecutive fiscal years.  The voting right shall continue until payment has been made.  Preferred shareholders also obtain the right to vote if we enter into a liquidation process.

Under Brazilian Corporate Law, shareholders representing at least 10% of the company’s voting capital have the right to demand that a cumulative voting procedure be adopted to entitle each common share to as many votes as there are board members and to give each common share the right to vote cumulatively for only one candidate or to distribute its votes among several candidates.  Furthermore, minority common shareholders holding at least 10% of our voting capital also have the right to appoint or dismiss one member to or from our Fiscal Council.

Preferred shareholders holding, individually or as a group, 10% of our total capital have the right to appoint and/or dismiss one member to or from our board of directors.  Preferred shareholders have the right to separately appoint one member to our Fiscal Council.

Our bylaws provide that, independently from the exercise of the rights above granted to minority shareholders, through cumulative voting process, the Brazilian federal government always has the right to appoint the majority of our directors.

Preemptive Rights

Pursuant to the Brazilian Corporate Law, each of our shareholders has a general preemptive right to subscribe for shares or securities convertible into shares in any capital increase, in proportion to the number of shares held by them.  In the event of a capital increase that would maintain or increase the proportion of capital represented by the preferred shares, holders of preferred shares would have preemptive rights to subscribe to newly issued preferred shares only.  In the event of a capital increase that would reduce the proportion of capital represented by the preferred shares, holders of preferred shares would have preemptive rights to subscribe to any new preferred shares in proportion to the number of shares held by them, and to common shares only to the extent necessary to prevent dilution of their interests in our total capital.

A period of at least 30 days following the publication of notice of the issuance of new shares or securities convertible into shares is allowed for exercise of the right, and the right is negotiable.  According to our bylaws, our board of directors may eliminate preemptive rights or reduce the exercise period in connection with a public exchange made to acquire control of another company or in connection with a public offering of shares or securities convertible into shares.

In the event of a capital increase by means of the issuance of new shares, holders of ADSs, of common or preferred shares, would have, except under circumstances described above, preemptive rights to subscribe for any class of our newly issued shares.  However, holders of ADSs may not be able to exercise the preemptive rights relating to the preferred shares underlying their ADSs unless a registration statement under the Securities Act is effective with respect to those rights or an exemption from the registration requirements of the Securities Act is available.  See Item 3. “Key Information—Risk Factors—Risks Relating to Our Equity and Debt Securities.”

143

Redemption and Rights of Withdrawal

Brazilian law provides that, under limited circumstances, a shareholder has the right to withdraw his or her equity interest from the company and to receive payment for the portion of shareholder’s equity attributable to his or her equity interest.

This right of withdrawal may be exercised by the holders of the adversely affected common or preferred shares in the event that we decide:

•to create preferred shares or to increase the existing classes of preferred shares, without preserving the proportions to any other class of preferred shares, except as set forth in or authorized by our bylaws; or

•to change the preferences, privileges or redemption or amortization conditions of any class of preferred shares or to create a new class of preferred shares entitled to more favorable conditions than the existing classes.

Holders of our common shares may exercise their right of withdrawal in the event we decide:

•to merge into another company or to consolidate with another company, subject to the conditions set forth in the Brazilian Corporate Law; or

•to participate in a centralized group of companies as defined under the Brazilian Corporate Law and subject to the conditions set forth therein.

The right of withdrawal may also be exercised by our dissenting shareholders in the event we decide:

•to reduce the mandatory distribution of dividends;

•to change our corporate purposes;

•to spin-off a portion of our company, subject to the conditions set forth in the Brazilian Corporate Law;

•to transfer all of our shares to another company or to receive shares of another company in order to make the company whose shares are transferred a wholly owned subsidiary of our company, known as incorporação de ações; or

•to acquire control of another company at a price, which exceeds the limits set forth in the Brazilian Corporate Law, subject to, the conditions set forth in the Brazilian Corporate Law.

This right of withdrawal may also be exercised in the event that the entity resulting from a merger, incorporação de ações, as described above, or consolidation or spin-off of a listed company fails to become a listed company within 120 days of the shareholders’ meeting at which such decision was taken.

Any redemption of shares arising out of the exercise of such withdrawal rights would be made based on the book value per share, determined on the basis of the last balance sheet approved by our shareholders.  However, if a shareholders’ meeting giving rise to redemption rights occurred more than 60 days after the date of the last approved balance sheet, a shareholder would be entitled to demand that his or her shares be valued on the basis of a new balance sheet dated within 60 days of such shareholders’ meeting.  The right of withdrawal lapses 30 days after publication of the minutes of the shareholders’ meeting that approved the corporate actions described above.  We would be entitled to reconsider any action giving rise to withdrawal rights within ten days following the expiration of such rights if the withdrawal of shares of dissenting shareholders would jeopardize our financial stability.

144

Other Shareholders’ Rights

According to the Brazilian Corporate Law, neither a company’s bylaws nor actions taken at a general meeting of shareholders may deprive a shareholder of some specific rights, such as:

•the right to participate in the distribution of profits;

•the right to participate equally and ratably in any remaining residual assets in the event of liquidation of the company;

•the right to supervise the management of the corporate business as specified in the Brazilian Corporate Law;

•the right to preemptive rights in the event of a subscription of shares, debentures convertible into shares or subscription bonuses (other than with respect to a public offering of such securities, as may be set out in the bylaws); and

•the right to withdraw from the company in the cases specified in the Brazilian Corporate Law.

Liquidation

In the event of a liquidation, holders of preferred shares are entitled to receive, prior to any distribution to holders of common shares, an amount equal to the paid-in capital with respect to the preferred shares.

Conversion Rights

According to our bylaws, our common shares are not convertible into preferred shares, nor are preferred shares convertible into common shares.

Liability of Our Shareholders for Further Capital Calls

Neither Brazilian law nor our bylaws provide for capital calls.  Our shareholders’ liability for capital calls is limited to the payment of the issue price of the shares subscribed or acquired.

Form and Transfer

Our shares are registered in book-entry form and we have hired Banco do Brasil to perform all the services of safe-keeping and transfer of shares.  To make the transfer, Banco do Brasil makes an entry in the register, debits the share account of the transferor and credits the share account of the transferee.

Our shareholders may choose, at their individual discretion, to hold their shares through the Companhia Brasileira de Liquidação e Custódia or CBLC.  Shares are added to the CBLC system through Brazilian institutions, which have clearing accounts with the CBLC.  Our shareholder registry indicates which shares are listed on the CBLC system.  Each participating shareholder is in turn registered in a registry of beneficial shareholders maintained by the CBLC and is treated in the same manner as our registered shareholders.

145

Dispute Resolution

Our bylaws provide for mandatory dispute resolution through arbitration, in accordance with the rules of the Câmara de Arbitragem do Mercado (Market Arbitration Chamber), with respect to any dispute regarding us, our shareholders, the officers, directors and Fiscal Council members and involving the provisions of the Brazilian Corporate Law, our bylaws, the rules of the CMN, the Central Bank of Brazil and the CVM or any other capital markets legislation, including the provisions of any agreement entered into by us with any stock exchange or over-the-counter entity registered with the CVM, relating to adoption of differentiated corporate governance practices.

However, decisions of the Brazilian federal government, as exercised through voting in any general shareholders’ meeting, are not subject to this arbitration proceeding, in accordance with Article 238 of the Brazilian Corporate Law.

Self-dealing Restrictions

Our principal shareholder, the Brazilian federal government, and the members of our board of directors, board of executive officers and Fiscal Council are required, in accordance with our bylaws, to:

•refrain from dealing with our securities either in the one-month period prior to any fiscal year-end, up to the date when our financials are published, or in the period between any corporate decision to raise or reduce our stock capital, to distribute dividends or stock, and to issue any security, up to the date when the respective public releases are published; and

•communicate to us and to the stock exchange their periodical dealing plans with respect to our securities, if any, including any change or default in these plans.  If the communication is an investment or divestment plan, the frequency and planned quantities must be included.

Restrictions on Non-Brazilian Holders

Non-Brazilian holders face no legal restrictions on the ownership of our common or preferred shares or of ADSs based on our common or preferred shares, and are entitled to all the rights and preferences of such common or preferred shares, as the case may be.

However, the ability to convert dividend payments and proceeds from the sale of common or preferred shares or preemptive rights into foreign currency and to remit such amounts outside Brazil is subject to restrictions under foreign investment legislation which generally requires, among other things, the registration of the relevant investment with the Central Bank of Brazil.  Nonetheless, any non-Brazilian holder who registers with the CVM in accordance with Resolution No. 2,689 may buy and sell securities on the BM&FBOVESPA without obtaining a separate certificate of registration for each transaction.

In addition, Annex III to Resolution No. 1,289 of the CMN, as amended, known as Annex III Regulations, allows Brazilian companies to issue depositary receipts in foreign exchange markets.  We currently have an ADR program for our common and preferred shares duly registered with the CVM and the Central Bank of Brazil.  The proceeds from the sale of ADSs by holders outside Brazil are free of Brazilian foreign investment controls.

Transfer of Control  

According to Brazilian law and our bylaws, the Brazilian federal government is required to own at least the majority of our voting shares.  Therefore, any change in our control would require a change in the applicable legislation.

146

Disclosure of Shareholder Ownership  

Brazilian regulations require that any person or group of persons representing the same interest that has directly or indirectly acquired or sold an interest corresponding to 5% of the total number of shares of any type or class must disclose its share ownership or divestment to the CVM and the BM&FBOVESPA.  In addition, a statement containing the required information must be published in the newspapers.  Any subsequent increase or decrease by 5% or more in ownership of shares of any type or class must be similarly disclosed.

Directors may vote on a proposal, arrangement or contract in which they are interested. However, interested directors must declare the nature of their interest at a directors’ meeting. If the interested directors declare their interest, their votes are counted and they are counted in the quorum of such meeting.

The directors may, in PifCo’s name, exercise their powers to borrow money, issue debt securities and to mortgage or charge any of the undertaking or property of PifCo and are generally responsible for its day-to-day management and administration.

Directors are not required to own shares.

Rights and Obligations of Shareholders

Dividends

PifCo’s shareholder may declare dividends in a general meeting but the dividends cannot exceed the amount recommended by the directors.  The directors may pay the shareholder interim dividends and may, before recommending any dividend, set aside reserves out of profits.  The directors can invest these reserves in their discretion or employ them in PifCo’s business.

Dividends may be paid in cash or in kind but may only be paid out of profits or, subject to certain restrictions of Cayman Islands law, a share premium account.

Voting Rights

Votes may be cast at a general meeting by a show of hands or by a poll (if demanded by one or more members present in person or by proxy entitled to vote prior to or on the declaration of the result of the show of hands).  On a vote by a show of hands, each shareholder or shareholder represented by proxy has one vote.  On a vote by a poll, each shareholder or shareholder represented by proxy has one vote for each share owned.

Directors are elected by ordinary resolution by the shareholders at general meetings or by a board resolution of the directors.  Shareholders are not entitled to vote at a general meeting unless calls or other amounts payable on their shares have been paid.  In lieu of voting on a matter at a general meeting, the shareholders entitled to vote on that matter may adopt the matter by signing a written resolution.

Redemption

PifCo may issue shares, which are redeemable by PifCo or by its shareholder, on such terms and in such manner as the directors may determine before the issuance of such shares.  PifCo may repurchase its own shares on such terms and in such manner as the directors may determine and agree with the relevant shareholder.

Shareholder Rights Upon Liquidation

If PifCo is liquidated, the liquidator may (in accordance with an ordinary shareholder resolution):

•set a fair value on PifCo’s assets, divide all or part of PifCo’s assets among the shareholders and determine how the assets will be divided among shareholders or classes of shareholders; and

•vest all or part of PifCo’s assets in trustees.

Shareholders will not be compelled to accept any securities on which there is a liability.

148

Calls on Shares

Directors may make calls on the shareholders to the extent any amounts remain unpaid on their shares (subject to giving such shareholder at least fourteen days notice specifying the time or times of payment).  Each shareholder shall pay to the company the amounts called on such shares.

Change to Rights of Shareholders

Shareholders may change the rights of their class of shares by:

•getting the written consent of two-thirds of the shareholders of that class; or

•passing a special resolution at a meeting of the shareholders of that class.

There are no general limitations on the rights to own shares specified by the articles.

General Meetings

A general meeting may be convened:

•by the directors at any time; or

•by any two shareholders holding not less than 10% of the paid-up voting share capital of PifCo, by written request.

Notice of a general meeting is given to all shareholders.

All business carried out at a general meeting is considered special business except:

•sanctioning a dividend;

•consideration of the accounts, balance sheets, and ordinary report of the directors and auditors;

•appointment and removal of directors; and

•fixing of remuneration of the auditors.

Unanimous shareholder consent is required to carry out special business at a meeting unless notice of the special business is given in the notice of the meeting.  A quorum of shareholders is required to be present at any meeting in order to carry out business.  One or more shareholders holding at least a majority of the shares of PifCo that are present in person or represented by proxy is a quorum.

There is no requirement under Cayman Islands law to convene an annual meeting or to convene any general meeting of the shareholders.  The directors are permitted to designate any general meeting of shareholders as an annual general meeting.

Liability of Shareholders

In normal circumstances, the liability of any shareholder to PifCo is limited to the amount, which such shareholder has agreed to pay in respect of the subscription of his shares.

149

Changes in Capital

PifCo may increase its authorized share capital by ordinary resolution. The new shares will be subject to all of the provisions to which the original shares are subject.

PifCo may also by ordinary resolution:

•consolidate and divide all or any of its share capital into shares of a larger amount than its existing shares;

•convert all or any part of its paid-up shares into stock and reconvert that stock into paid-up shares of any denomination;

•split existing shares into shares of a smaller amount, subject to the provisions of Section 13 of the Companies Law; and

•cancel any shares, which, at the date of the resolution, are not held or agreed to be held by any person and diminish the amount of its share capital by the amount of the shares so cancelled.

PifCo may reduce its share capital and any capital redemption reserve by special resolution in accordance with relevant provision of Cayman Islands law.

Indemnity

PifCo’s directors and officers are indemnified out of its assets and funds against all actions, proceedings, costs, charges, expenses, losses, damages or liabilities which they incur or sustain in or regarding the conduct of PifCo’s business or affairs in the execution or discharge of their respective duties, powers, authorities or discretions.  Under PifCo’s Memorandum of Association, directors and officers are excused from all liability to PifCo, except for any losses, which arise as a result of such party’s own dishonesty.

Accounts

Accounts relating to PifCo’s affairs are kept in such manner as may be determined from time to time by the directors and may be audited in such manner as may be determined from time to time by the directors.  There is, however, no requirement as a matter of Cayman Islands law to have PifCo’s accounts audited.

Amendment of the Articles

PifCo may, by special resolution of the shareholders, amend its memorandum and articles of association.

Transfer out of Jurisdiction

PifCo may, by special resolution of the shareholders, transfer out of the Cayman Islands into any jurisdiction permitting such transfer.

Petrobras

Assignment Agreement (Cessão Onerosa )

On September 3, 2010, we entered into an agreement with the Brazilian federal government, under which the government assigned to us the right to conduct activities for the exploration and production of oil, natural gas and other fluid hydrocarbons in specified pre-salt areas, subject to a maximum production of five billion barrels of oil equivalent. The Assignment Agreement was entered into pursuant to specific provisions of Law No. 12,276. The draft of the Assignment Agreement was approved by our Board of Directors on September 1, 2010 and by the CNPE on September 1, 2010, following a negotiation between us and the Brazilian federal government based on independent experts reports obtained by us and the ANP according to a valuation procedure as required by Law No. 12,276.

Basic Terms

Purpose.  Under the Assignment Agreement, we paid an initial contract price for the right to conduct activities of exploration and production of oil, natural gas and other fluid hydrocarbons in specified pre-salt areas, subject to a maximum production of five billion barrels of oil equivalent. Although the Assignment Agreement grants certain rights to us that are similar to those of a concession, the Assignment Agreement is a specific regime for exploration and production, not a concession under Brazilian law.

Area Covered.  The Assignment Agreement covers six firm blocks plus one contingent block, located in the pre-salt areas and identified in the Assignment Agreement. These blocks are located in the Santos Basin and have expected geological characteristics similar to the discoveries made elsewhere in the pre-salt area.

Supervision and Inspection.  The ANP has regulatory authority and inspection rights over our activities in the areas subject to the Assignment Agreement, as well as over our compliance with the Assignment Agreement.

Costs and Risks.  All our exploration, development and production activities under the Assignment Agreement will be conducted at our expense and at our risk.

Price

The initial contract price for our rights under the Assignment Agreement was R$74,807,616,407, which was equivalent to U.S.$42,533,327,500 as of September 1, 2010. As provided by Law No. 12,276, the contract price was determined by negotiation between us and the Brazilian federal government, based on the reports of independent experts obtained by us and by the ANP, which took into consideration a number of factors, including market conditions, current oil prices and industry costs.

We have used part of the proceeds of our sale of shares in the global offering for the payment of the initial contract price, including the use of LFTs we received from the Brazilian federal government in the global offering. The LFTs were valued at the same price at which they were valued for purposes of the global offering.

151

The Assignment Agreement sets forth the initial prices and volumes for each block, as follows:

	INITIAL EVALUATIONS
	Volume	Price	Value
	(million of boe)	(U.S.$/boe)	(U.S.$)
Block 1 Florim	467	9.0094	4,207,389,800
Block 2 Franco	3,058	9.0400	27,644,320,000
Block 3 Guará South	319	7.9427	2,533,721,300
Block 4 Surrounding Iara	600	5.8157	3,489,420,000
Block 5 Tupi South	128	7.8531	1,005,196,800
Block 6 Tupi Northeast	428	8.5357	3,653,279,600
Block 7 (contingent block) Peroba	—	—	—
Initial Contract Price of the Assignment Agreement			42,533,327,500

Duration

The term of the Assignment Agreement is 40 years, which may be extended for an additional five years, upon our request, in cases of (i) force majeure, (ii) delay in obtaining applicable environmental licenses, provided that such delay is attributable only to the relevant environmental authority, (iii) suspension of the activities by determination of the ANP, or (iv) changes in the geological conditions forecast for each area. The extension will only apply to areas in which the ANP identifies the occurrence of one of the events specified above. The ANP will take into account the period of time of the delay occurred to determine the length of the extension, subject to the five-year limit indicated above. In addition, the duration of the Assignment Agreement is subject to the revision process.

Contingent Area

We may request that the Brazilian federal government grant us the right to perform the activities set forth in the mandatory exploration program in the contingent block within four years from the date of the Assignment Agreement, and provided that it is proved, based on oil and gas industry best practices, that the total volume recoverable in the other blocks is less than the maximum volume initially provided by the Assignment Agreement.

The activities set forth in the mandatory exploration program for the contingent block must be performed within the term of the exploration phase. At any time, in case we or the Brazilian federal government identify the possibility of producing the maximum volume initially provided for in the Assignment Agreement in the other blocks, we will be required to return the contingent block to the Brazilian federal government immediately.

Revision

The Assignment Agreement is subject to a revision process. We will notify the Brazilian federal government and the ANP ten months before the date expected for the declaration of commerciality of each area covered by the agreement, in order to initiate the revision process, which will begin immediately after the declaration of commerciality of each field in each of the blocks. The revision process will be concluded when we issue our last declaration of commerciality, based on each area’s revised prices and volumes, for all the areas subject to the Assignment Agreement. The contingent area will also be subject to the revision process.

The conclusion of the revision process may result in the renegotiation of the contract price, the maximum production volume of five billion barrels of oil equivalent, the duration, and the minimum levels of goods and services to be acquired from Brazilian providers.

152

If the revised contract price is higher than the initial contract price, we may agree with the Brazilian federal government on one or more of the following payment options: (i) a payment to be made by us, in cash or LFTs, to the Brazilian federal government in an amount equal to the difference between the revised contract price (resulting from the revision process) and the initial contract price; or (ii) a reduction in the maximum production volume of five billion barrels of oil equivalent, where we may agree to return one or more of the areas covered by the Assignment Agreement. If the revised contract price is lower than the initial contract price, then the Brazilian federal government will pay us in cash, LFTs, securities issued by us or through other means agreed between us, the difference between the revised contract price and the initial contract price. In either case, the difference between the revised contract price and the initial contract price in U.S. dollars will be converted into Brazilian reais, based on the average PTAX exchange rate for the purchase of U.S. dollars published by the Central Bank of Brazil for the 30 days preceding the revision of each area and will be adjusted by the interest rate of the Brazilian Special Clearance and Custody System (Sistema Especial de Liquidação e Custódia), or the SELIC rate, until the payment date. Payments must be made within three years of the completion of the revision process.

The revision process will be based on reports of independent experts to be engaged by us and by the ANP. The following factors will be considered in the revision process: Reference Date:  the date of the reports obtained by us and the ANP for purposes of negotiating the initial contract price;

•Discount Rate:  a discount rate of 8.83% per year;

•Oil Reference Price:  will be equal to the average trading price of the month preceding the revision date (Crude Light West Texas Intermediate — WTI), in U.S.$/barrel, as published by the New York Mercantile Exchange, the NYMEX, under the code “CL,” for the futures contract of eighteenth maturity, minus the differential in relation to Brent crude oil. The Brent crude oil differential (the price of WTI minus the Brent price) shall be calculated using yearly averages of monthly projections as specified in the most recently published reports of the Pira Energy Group (available on their website for a fee) for the year following the revision, or, if not available, a comparable forecast published by an international entity renowned for its technical competence in the oil and natural gas industry. For each area under the Assignment Agreement, the calculation of the differential of the price of barrel of oil equivalent applicable to each area in relation to Brent crude oil shall be based on the most recent fluid characterization data available as of the revision date, and shall be conducted in accordance with the methodology specified in the ANP Ordinance No. 206/2000.

•Natural Gas Reference Price in U.S.$/MMBtu:  the natural gas reference price equals the price in the reference market (PMR) minus installments in connection with transportation fees (TTr), processing fees (TP), transfer fees (TT) and sales expenses (DC), according to the following formula: PRGN = PMR - (TTr + TP + TT + DC), where:

oThe price in the reference market (PMR) in U.S.$/MMBtu is the average sale price of domestic natural gas in the twelve months preceding the revision date, weighed per volume, consistent with our practices of firm commitments to the non-thermoelectric market in the states of Rio de Janeiro and São Paulo.

oTransportation fees (TTr) in U.S.$/MMBtu are contractual fees of gas pipelines used to transport natural gas between our processing plants and the delivery points, as follows: TTr = ∑ TTr (n) , where TTr (n) equals the transportation fees of gas pipeline n.

oThe processing fees (TP) in U.S.$/MMBtu are based on the cost of processing pre-salt natural gas, in our Cabiúnas terminal in Macaé, State of Rio de Janeiro, taking into account the revenues from the commercialization of liquid hydrocarbons which will result from the processing of natural gas.

oThe transfer fees (TT) in U.S.$/MMBtu are based on the cost of transferring natural gas from the pre-salt areas from our production units to the Cabiúnas terminal.

153

oSales Expenses (DC) in U.S.$/MMBtu correspond to the costs incurred in the commercialization of natural gas, which include, among others, the preparation and management of natural gas commercialization contracts, logistics costs of supplying natural gas and invoicing costs.

oCalculations of the processing and transfer fees will be based on audited information we have available for equivalent projects involving processing and transfer of pre-salt natural gas. Calculations of sales expenses will be based on audited information we have available regarding natural gas commercialization.

•Tax:  Applicable taxes will be the Brazilian taxes applicable to fields under the Assignment Agreement, in force at the revision period;

•Cost: 

oFor operations between the date of the execution of the Assignment Agreement and the revision date, the cost shall be the effective cost incurred by us, in U.S.$, separately for each area under the Assignment Agreement, provided they have been audited and are consistent with common market practices.

oInvestments and operational costs, and additional future costs will be estimated according to best practices in the oil industry, taking into consideration the operational environment, and based on the market prices practiced for each good or service at the revision date.

oLease and rent:  in case lease and rent are applicable, they will be considered according to best practices in the oil industry, for production assets including, but not limited to, production units and underwater equipment. Lease and rent payments will be estimated based on daily lease rates of recent lease or rental contracts of Stationary Production Units that have an equivalent market value (CAPEX). Any taxes due pursuant to the remittance of lease and rent payments will be added to the lease and rent payments.

oInvestment costs, operating costs and additional expenses will be calculated in U.S. dollars; and

•Exchange Rate:  the exchange rate to be applied in the conversions from U.S. dollars to Brazilian reais  will be the average PTAX exchange rate for the purchase of U.S. dollars (calculated by the Brazilian Central Bank) for the 30 days immediately preceding the payment.

Phases

Our performance under the Assignment Agreement is divided into two phases:

•Exploration phase.  This phase comprises the appraisal for purposes of determining the commerciality of any discoveries of oil, natural gas and other fluid hydrocarbons. The exploration phase began as of the date of the execution of the Assignment Agreement and will end upon the declaration of commerciality of each respective reservoir discovered in each area covered by the Assignment Agreement. We will have four years, which may be extended for an additional two-year period, to comply with the mandatory working program and other ANP-approved activities as set forth in the Assignment Agreement. If we discover oil and decide to appraise such discovery, we must issue a notice of discovery to the ANP. Upon completion of the mandatory working program in each block, we may notify the ANP in writing that we are ending the exploration phase by issuing a declaration of commerciality of each reservoir discovered within a given block or that there have been no discoveries which would justify the development of a given block.

•Production Phase.  The production phase begins as of the date of delivery of the declaration of commerciality by us to the ANP, and it lasts until the termination of the Assignment Agreement. It comprises a development period, during which we will carry out activities pursuant to a development plan approved by the ANP. Following the development period, we may start production pursuant to a notification to the ANP.

154

Mandatory Exploration Program

During the exploration phase, we are required to perform a mandatory working program, as specified in an annex to the Assignment Agreement. We may perform other activities outside the scope of the mandatory working program, provided that such activities are approved by the ANP.

The ANP will impose fines on us for delays in the performance of the mandatory exploration program. If the delay is less than24 months, the fine will correspond to the amount of such non-performed activities, proportional to the number of outstanding days. If the delay is greater than 24 months, then the fine will be equal to twice the amount of the activities of the mandatory exploration program for the relevant block.

Reallocation of Volumes

The Brazilian federal government and we may negotiate the reallocation of the volume of oil and natural gas originally assigned for each block, observing the price per barrel of oil equivalent applicable to each area, in the following scenarios: (i) the relevant environmental authority does not grant a permanent license for the performance of oil and natural gas exploration and production activities in a certain block or field, or (ii) the production of the volume allotted for any block is not feasible under petroleum industry best practices due to the geological features of the reservoirs, observing the economic parameters established in the revision process (as discussed below).

Once reallocations are completed, the number of barrels of oil equivalent to be produced in the new block will equal the multiplication of (i) the number of barrels of oil equivalent that were reallocated from the original block to the new block and (ii) the value of the barrel of oil equivalent in the original block, to be divided by the value of the barrel of oil equivalent in the new block.

If it is not possible to reallocate all of the volumes of oil and natural gas not produced by us, the reallocation procedure will be performed in part, and the Brazilian federal government will pay us the amount resulting from the multiplication of the volume not subject to the reallocation by the value of the barrel in the block to which the reallocation has been made.  This dollar amount will be converted to reais  using the average PTAX exchange rate for the purchase of U.S. dollars for the 30 days preceding the date of the reallocation process of such block, and adjusted by the SELIC rate during the period between the date of the reallocation process of such block and the date of payment by the Brazilian federal government.

If it is determined that it is not possible to reallocate any volumes of oil, natural gas and other hydrocarbons fluids as described above, the Brazilian federal government will reimburse us for an amount equivalent to total volume of barrels of oil equivalent that was not produced multiplied by the dollar price of barrel of oil equivalent applicable to the relevant block, converted in reais  using the average PTAX exchange rate for the purchase of U.S. dollars for the 30 days preceding the date of the reallocation process, and adjusted by the SELIC rate from the date of the reallocation process of such block to the date of payment by the Brazilian federal government.

The manner and terms of payment of the reimbursement in either case will be negotiated by us and the Brazilian federal government. Payments will be made no later than three years after the conclusion of the reallocation process.

155

Unitization

A reservoir covered by a block assigned to us in the Assignment Agreement may extend to adjacent areas outside such block. In such case, we must notify the ANP immediately after identifying the extension and we will be prevented from performing the exploration and production activities within such block, until we have negotiated an unitization agreement with the third-party concessionaire or contractor under a different exploration and production regime who has rights over such adjacent areas.  The ANP will inform such third-party that we should negotiate an “Unitization Agreement.” If the adjacent area is not licensed, the Brazilian federal government shall indicate a representative to negotiate with us.

If the parties are unable to reach an agreement within a deadline established by the ANP, the agency will determine the terms and obligations related to such unitization, on the basis of an expert report, and will also notify us and the third-party or the Brazilian federal government representative, as applicable, of such determination. Until the unitization agreement is approved by the ANP, operations for the development and production of such reservoir must remain suspended, unless otherwise authorized by the ANP. Our refusal to execute the unitization agreement will imply the return to the Brazilian federal government of the area subject to the unitization process. 

Licenses, Authorizations and Permissions

We are required to obtain all licenses, authorizations, permissions and rights required by applicable law, as determined by the relevant authorities or based on rights of third parties whether or not contemplated in the Assignment Agreement, that may be necessary to perform our operations under the Assignment Agreement.

Environmental

We are required to preserve the environment and protect the ecosystem in the area subject to the Assignment Agreement, to avoid damages and losses to the fauna, flora and natural resources, and we will be liable for all damages arising from our operations, including for any recovery measures in the case of damage to the environment.

Brazilian Content

The Assignment Agreement requires us to acquire a minimum level of goods and services from Brazilian providers and to provide equal conditions for such providers to compete with foreign companies for the sale of goods and services. The minimum Brazilian content requirement is listed in the Assignment Agreement and specifies certain equipment, goods and services, as well as different levels of content requirement in accordance with the different phases and periods of the Assignment Agreement. The Brazilian content threshold is 37% for the exploration phase. For the development period, it is (i) 55% for the development periods beginning production by 2016, (ii) 58% for the development periods beginning production between 2017 and 2019, and (iii) 65% for the development periods beginning production as of 2020. Despite the minimum percentages set forth for each development period timeframes, the average global percentage of Brazilian content in the development period shall be at least 65%. If we fail to comply with the Brazilian content obligations, we may be subject to specific fines imposed by the ANP.

Royalties and expenses with Research and Development

Once we begin commercial production in each field, we will be required to pay monthly royalties in an amount equal to 10% of the oil and natural gas production. We are also required to invest 0.5% of our yearly gross revenues from oil, natural gas and other fluid hydrocarbons production under the Assignment Agreement in research and development activities related to energy and environmental issues being conducted in universities and national research and technical development institutions, public or private, previously registered with the ANP for this purpose.

156

Miscellaneous Provisions

•We shall not assign our rights under the Assignment Agreement.

•Any breach of the Assignment Agreement or of any regulations of the ANP caused by us may lead to administrative sanctions and fines to be imposed by the ANP, in accordance with applicable legislation and the terms of this Assignment Agreement, and respecting the due process of law.

•If our breach of the Assignment Agreement is considered by the ANP not to be significant, intentional, or a result of negligence, imprudence or recklessness, or it is proved that we worked diligently to curing such breach, the ANP may, instead of terminating the Assignment Agreement, apply the sanctions mentioned above.

•The Assignment Agreement shall terminate upon (i) the production of the maximum volume of barrels of oil equivalent as specified in the Assignment Agreement, (ii) the expiration of the term, or (iii) upon the request of the ANP, if we fail to observe the cure period established by the ANP in connection with the breach of an obligation that proves relevant for the continuation of operations in each block. Such cure period may not be less than 90 days, except in cases of extreme emergency.

•The Brazilian federal government and we will only be excused from the performance of the activities set forth in the Assignment Agreement in cases of force majeure, which includes, among others, delays in the obtaining an environmental license, provided that such delay is attributable only to the relevant environmental authority.

•The Assignment Agreement is subject to Brazilian law.

•The Brazilian federal government and we will use our best efforts to settle any disputes amicably. If we are unable to do so, we may submit such dispute for arbitral review by the Brazilian Federal Attorney’s Office (Advocacia-Geral da União Federal), which may rely on independent experts to address technical matters, or initiate a legal proceeding at the Federal Court located in Brasília, Brazil.

Petrobras Exchange Controls

There are no restrictions on ownership of the common or preferred shares by individuals or legal entities domiciled outside Brazil.

The right to convert dividend payments and proceeds from the sale of shares into foreign currency and to remit such amounts outside Brazil may be subject to restrictions under foreign investment legislation, which generally requires, among other things, that the relevant investments be registered with the Central Bank of Brazil.  If any restrictions are imposed on the remittance of foreign capital abroad, they could hinder or prevent Companhia Brasileira deliquidação e Custódia, or CBLC, as custodian for the common and preferred shares represented by the ADSs, or registered holders who have exchanged ADSs for common shares or preferred shares, from converting dividends, distributions or the proceeds from any sale of such common shares or preferred shares, as the case may be, into U.S. dollars and remitting the U.S. dollars abroad.

Foreign investors may register their investment under Law No. 4,131 of September 3, 1962 or Resolution No. 2,689. Registration under Resolution No. 2,689 affords favorable tax treatment to foreign investors who are not resident in a tax haven, as defined by Brazilian tax laws. See “—Taxation Relating to Our ADSs and Common and Preferred Shares—Brazilian Tax Considerations.”

Under Resolution No. 2,689, foreign investors may invest in almost all financial assets and engage in almost all transactions available in the Brazilian financial and capital markets, provided that certain requirements are fulfilled.  In accordance with Resolution No. 2,689, the definition of foreign investor includes individuals, legal entities, mutual funds and other collective investment entities, domiciled or headquartered abroad.

Under Resolution No. 2,689, a foreign investor must:

•appoint at least one representative in Brazil, with powers to perform actions relating to its investment;

•appoint an authorized custodian in Brazil for its investments;

•register as a foreign investor with the CVM; and

•register its foreign investment with the Central Bank of Brazil.

Securities and other financial assets held by a Resolution No. 2,689 investor must be registered or maintained in deposit accounts or under the custody of an entity duly licensed by the Central Bank of Brazil or the CVM.  In addition, any transfer of securities held under Resolution No. 2,689 must be carried out in the stock exchanges or through organized over-the-counter markets licensed by the CVM, except for transfers resulting from a corporate reorganization or occurring upon the death of an investor by operation of law or will.

Holders of ADSs who have not registered their investment with the Central Bank of Brazil could be adversely affected by delays in, or refusals to grant, any required government approval for conversions of payments made in reais and remittances abroad of these converted amounts.

Annex III Regulations provide for the issuance of depositary receipts in foreign markets with respect to shares of Brazilian issuers.  The depositary of the ADSs has obtained from the Central Bank of Brazil an electronic certificate of registration with respect to our existing ADR program.  Pursuant to the registration, the custodian and the depositary will be able to convert dividends and other distributions with respect to the relevant shares represented by ADSs into foreign currency and to remit the proceeds outside Brazil.  Following the closing of an international offering, the electronic certificate of registration will be amended by the depositary with respect to the ADSs sold in the international offering and will be maintained by the Brazilian custodian for the relevant shares on behalf of the depositary.

158

In the event that a holder of ADSs exchanges such ADSs for the underlying shares, the holder will be entitled to continue to rely on such electronic registration for five business days after the exchange.  Thereafter, unless the relevant shares are held pursuant to Resolution No. 2,689 by a duly registered investor, or a holder of the relevant shares applies for and obtains a new certificate of registration from the Central Bank of Brazil, the holder may not be able to convert into foreign currency and to remit outside Brazil the proceeds from the disposition of, or distributions with respect to, the relevant shares, and the holder, if not registered under Resolution No. 2,689, will be subject to less favorable Brazilian tax treatment than a holder of ADSs.  In addition, if the foreign investor resides in a “tax haven” jurisdiction, the investor will be also subject to less favorable tax treatment.  See Item 3. “Key Information—Risk Factors—Risks Relating to Our Equity and Debt Securities” and “—Taxation Relating to Our ADSs and Common and Preferred Shares—Brazilian Tax Considerations.”

PifCo

There are:

•no governmental laws, decrees or regulations in Cayman Islands that restrict the export or import of capital, including dividend and other payments to holders of notes who are not residents of the Cayman Islands, provided that such holders are not resident in countries subject to certain sanctions by the United Nations or the European Union; and

•no limitations on the right of nonresident or foreign owners imposed by Cayman Island law or PifCo’s Memorandum of Association to hold or vote PifCo’s shares.

Taxation Relating to Our ADSs and Common and Preferred Shares

The following summary contains a description of material Brazilian and U.S. federal income tax considerations that may be relevant to the purchase, ownership and disposition of preferred or common shares or ADSs by a holder.  This summary does not describe any tax consequences arising under the laws of any state, locality or taxing jurisdiction other than Brazil and the United States.

This summary is based upon the tax laws of Brazil and the United States as in effect on the date of this annual report, which are subject to change (possibly with retroactive effect).  This summary is also based upon therepresentations of the depositary and on the assumption that the obligations in the deposit agreement and any related documents will be performed in accordance with their respective terms.

This description is not a comprehensive description of the tax considerations that may be relevant to any particular investor, including tax considerations that arise from rules that are generally applicable to all taxpayers or to certain classes of investors or rules that investors are generally assumed to know.  Prospective purchasers of common or preferred shares or ADSs should consult their own tax advisors as to the tax consequences of the acquisition, ownership and disposition of common or preferred shares or ADSs.

There is no income tax treaty between the United States and Brazil. In recent years, the tax authorities of Brazil and the United States have held discussions that may culminate in such a treaty.  We cannot predict, however, whether or when a treaty will enter into force or how it will affect the U.S. Holders of common or preferred shares or ADSs.

159

Brazilian Tax Considerations

General

The following discussion summarizes the material Brazilian tax consequences of the acquisition, ownership and disposition of preferred or common shares or ADSs, as the case may be, by a holder that is not deemed to be domiciled in Brazil for purposes of Brazilian taxation, also called a non-Brazilian holder.

Under Brazilian law, investors may invest in the preferred or common shares under Resolution No. 2,689 or under Law No. 4,131 of September 3, 1962.  The rules of Resolution No. 2,689 allow foreign investors to invest in almost all instruments and to engage in almost all transactions available in the Brazilian financial and capital markets, provided that certain requirements are met. In accordance with Resolution No. 2,689, the definition of foreign investor includes individuals, legal entities, mutual funds and other collective investment entities, domiciled or headquartered abroad.

Pursuant to this rule, foreign investors must: (i) appoint at least one representative in Brazil with powers to perform actions relating to the foreign investment; (ii) complete the appropriate foreign investor registration form; (iii) register as a foreign investor with the CVM; and (iv) register the foreign investment with the Central Bank of Brazil.

Securities and other financial assets held by foreign investors pursuant to Resolution No. 2,689 must be registered or maintained in deposit accounts or under the custody of an entity duly licensed by the Central Bank of Brazil or the CVM. In addition, securities trading is restricted to transactions carried out in the stock exchanges or organized over-the-counter markets licensed by the CVM.

Taxation of Dividends

Dividends paid by us, including stock dividends and other dividends paid in property to the depositary in respect of the ADSs, or to a non-Brazilian holder in respect of the preferred or common shares, are currently not subject to withholding income tax in Brazil, to the extent that such amounts are related to profits generated as of January 1, 1996. Dividends relating to profits generated prior to January 1, 1996 may be subject to Brazilian withholding income tax at varying rates, depending on the year the profits were generated.

We must pay to our shareholders (including non-Brazilian holders of common or preferred shares or ADSs) interest on the amount of dividends payable to them, at the SELIC rate, from the end of each fiscal year through the date of effective payment of those dividends. These interest payments are considered as fixed-yield income and are subject to withholding income tax at varying rates depending on the length of period of interest accrual. The tax rate varies from 15%, in case of interest accrued for a period greater than 720 days, 17.5% in case of interest accrued for a period between 361 and 720 days, 20% in case of interest accrued for a period between 181 and 360 days, and to 22.5%, in case of interest accrued for a period up to 180 days. However, the withholding income tax is reduced to 15% in the case of a non-Brazilian holder of ADSs or common or preferred shares investing under Resolution No. 2,689 who is not resident or domiciled in a country or other jurisdiction that does not impose income tax or imposes it at a maximum income tax rate lower than 20% (a Low or Nil Tax Jurisdiction) or, based on the position of the Brazilian tax authorities, a country or other jurisdiction where the local legislation does 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 shareholders (the Non-Transparency Rule).  See “—Clarifications on Non-Brazilian Holders Resident or Domiciled in a Low or Nil Tax Jurisdiction.”

Taxation on Interest on Shareholders’ Equity

Any payment of interest on shareholders’ equity to holders of ADSs or preferred or common shares, whether or not they are Brazilian residents, is subject to Brazilian withholding income tax at the rate of 15% at the time we record such liability, whether or not the effective payment is made at that time. See “— Memorandum and Articles of Incorporation of Petrobras — Payment of Dividends and Interest on Shareholders’ Equity.” In the case of non-Brazilian residents that are resident in a Low or Nil Tax Jurisdiction (including in the view of Brazilian authorities the jurisdictions to which the Non-Transparency Rule applies), the applicable withholding income tax rate is 25%.  See “—Clarifications on Non-Brazilian Holders Resident or Domiciled in a Low or Nil Tax Jurisdiction.”  The payment of interest at the SELIC rate that is applicable to payments of dividends applies equally to payments of interest on shareholders’ equity. The determination of whether or not we will make distributions in the form of interest on shareholders’ equity or in the form of dividends is made by our board of directors at the time distributions are to be made. We cannot determine how our board of directors will make these determinations in connection with future distributions.

160

Taxation of Gains

For purposes of Brazilian taxation on capital gains, two types of non-Brazilian holders have to be considered: (i) non-Brazilian holders of ADSs, preferred shares or common shares that are not resident or domiciled in a Low or Nil Tax Jurisdiction, and that, in the case of preferred or common shares have registered before the Central Bank of Brazil and the CVM in accordance with Resolution No. 2,689; and (ii) any other non-Brazilian holder, including non-Brazilian holders who invest in Brazil not in accordance with Resolution No. 2,689 (including registration under Law No. 4,131 of 1962) and who are resident or domiciled in a Low or Nil Tax Jurisdiction.  See “—Clarifications on Non-Brazilian Holders Resident or Domiciled in a Low or Nil Tax Jurisdiction.”

According to Law No. 10,833, dated December 29, 2003, capital gains realized on the disposition of assets located in Brazil by non-Brazilian holders, whether or not to other non-residents and whether made outside or within Brazil, may be subject to taxation in Brazil. With respect to the disposition of common or preferred shares, as they are assets located in Brazil, the non-Brazilian holder may be subject to income tax on any gains realized, following the rules described below, regardless of whether the transactions are conducted in Brazil or with a Brazilian resident. We understand the ADSs do not fall within the definition of assets located in Brazil for the purposes of this law, but there is still neither pronunciation from tax authorities nor judicial court rulings in this respect. Therefore, we are unable to predict whether such understanding will prevail in the courts of Brazil.

Although there are grounds to sustain otherwise, the deposit of preferred or common shares in exchange for ADSs may be subject to Brazilian taxation on capital gains if the acquisition cost of the preferred or common shares is lower than: (i) the average price per preferred or common share on a Brazilian stock exchange on which the greatest number of such shares were sold on the day of deposit; or (ii) if no preferred or common shares were sold on that day, the average price on the Brazilian stock exchange on which the greatest number of preferred or common shares were sold in the 15 trading sessions immediately preceding such deposit. In such a case, the difference between the amount previously registered and the average price of the preferred or common shares calculated as above, will be considered a capital gain.

The difference between the acquisition cost and the average price of the preferred or common shares calculated as described above will be considered to be a capital gain realized that is subject to taxation as described below. There are grounds to sustain that such taxation is not applicable with respect to non-Brazilian holders registered under the rules of Resolution No. 2,689 and not resident or domiciled in a Low or Nil Tax Jurisdiction.

The withdrawal of ADSs in exchange for preferred or common shares should not be considered as giving rise to a capital gain subject to Brazilian income tax, provided that on receipt of the underlying preferred or common shares, the non-Brazilian holder complies with the registration procedure with the Central Bank of Brazil as described below in “Registered Capital.”

161

Capital gains realized by a non-Brazilian holder on a sale or disposition of preferred or common shares carried out on a Brazilian stock exchange (which includes transactions carried out on the organized over-the-counter market) are:

•exempt from income tax when the non-Brazilian holder (i) has registered its investment in accordance with Resolution No. 2,689 and (ii) is not resident or domiciled in a Low or Nil Tax Jurisdiction; or

•in all other cases, including a case of capital gains realized by a non-Brazilian holder that is not registered in accordance with Resolution No. 2,689 and/or is resident or domiciled in a Low or Nil Tax Jurisdiction, subject to income tax at a 15% rate. In these cases, a withholding income tax at a rate of 0.005% of the sale value is levied on the transaction which can be offset against the eventual income tax due on the capital gain.

Any capital gains realized on a disposition of preferred or common shares that is carried out outside the Brazilian stock exchange are subject to income tax at the rate of 15%, or 25% in case of gains realized by a non-Brazilian holder that is domiciled or resident in a Low or Nil Tax Jurisdiction or a jurisdiction to which the Non-Transparency Rule applies. In this last case, for the capital gains related to transactions conducted on the Brazilian non-organized over-the-counter market with intermediation, the withholding income tax of 0.005% will also apply and can be offset against the eventual income tax due on the capital gain. 

In the case of a redemption of preferred or common shares or ADSs or a capital reduction made by us, the positive difference between the amount received by the non-Brazilian holder and the acquisition cost of the preferred or common shares or ADSs redeemed or reduced is treated as capital gain derived from the sale or exchange of shares not carried out on a Brazilian stock exchange market and is therefore generally subject to income tax at the rate of 15% or 25%, as the case may be.  See “—Clarifications on Non-Brazilian Holders Resident or Domiciled in a Low or Nil Tax Jurisdiction.”

Any exercise of preemptive rights relating to the preferred or common shares will not be subject to Brazilian taxation. Any gain on the sale or assignment of preemptive rights will be subject to Brazilian income taxation according to the same rules applicable to the sale or disposition of preferred or common shares.

No assurance can be made that the current preferential treatment of non-Brazilian holders of the ADSs and some non-Brazilian holders of the preferred or common shares under Resolution No. 2,689 will continue to apply in the future.

Clarifications on Non-Brazilian Holders Resident or Domiciled in a Low or Nil Tax Jurisdiction

Law No. 9,779 of January 1, 1999 states that, except for limited prescribed circumstances, income derived from transactions by a person resident or domiciled in a Low or Nil Tax Jurisdiction will be subject to withholding income tax at the rate of 25%. A Low or Nil Tax Jurisdiction is generally considered to be a country or other jurisdiction which does not impose any income tax or which imposes such tax at a maximum rate lower than 20%. Under certain circumstances, the Non-Transparency Rule is also taken into account for determining whether a country or other jurisdiction is a Low or Nil Tax Jurisdiction. In addition, Law No. 11,727 of June 23, 2008 introduced the concept of a “privileged tax regime”, which is defined as a tax regime which (i) does not tax income or taxes it at a maximum rate lower than 20%; (ii) grants tax benefits to non-resident entities or individuals (a) without the requirement to carry out a substantial economic activity in the country or other jurisdiction or (b) contingent on the non-exercise of a substantial economic activity in the country or other jurisdiction; or (iii) does not tax or that taxes foreign source income at a maximum rate lower than 20%; or (iv) does not provide access to information related to shareholding composition, ownership of assets and rights or economic transactions carried out. We believe that the best interpretation of Law No. 11,727/08 is that the new concept of a “privileged tax regime” will apply solely for purposes of the transfer pricing rules in export and import transactions and the thin capitalization rules and, would therefore generally not have an impact on the taxation of a non-Brazilian holder of preferred or common shares or ADSs, as discussed herein. However, we are unable to ascertain whether the privileged tax regime concept will also apply in the context of the rules applicable to Low or Nil Tax Jurisdictions, although the Brazilian tax authorities appear to agree with our position, in view of the provisions of the recently introduced Normative Ruling No. 1,037 of June 4, 2010.

162

Taxation of Foreign Exchange Transactions (IOF/Exchange)

Brazilian law imposes the IOF/Exchange on the conversion of reais  into foreign currency and on the conversion of foreign currency into reais.  Currently, for most foreign currency exchange transactions, the rate of IOF/Exchange is 0.38%. However, transactions in respect of investments carried out in the Brazilian financial and capital markets, including those made by a non-Brazilian holder in accordance with Resolution No. 2,689, are currently subject to the IOF/Exchange at a rate of (a) 2% for the inflow of funds (including with respect to simultaneous foreign exchange transactions upon the cancellation of depositary receipts on or after January 1, 2011 and destined for investments in equity securities traded on a stock exchange) and (b) 0% for the outflow of resources from Brazil related to these type of investments, including payments of dividends and interest on shareholders’ equity and the repatriation of funds invested in the Brazilian market. In any case, the Brazilian Executive Branch may increase such rates at any time, up to 25%, but not with retroactive effect.

Taxation on Bonds and Securities Transactions (IOF/Bonds)

Brazilian law imposes IOF/Bonds on transactions involving equity securities, bonds and other securities, including those carried out on a Brazilian stock exchange. The rate of IOF/Bonds applicable to transactions involving preferred or common shares is currently zero. However, the Brazilian government may increase such rate at any time up to 1.5% of the transaction amount per day, but the tax cannot be applied retroactively. The deposit of preferred or common shares for issuance of ADSs is subject to IOF/Bonds at a rate of 1.5%.

Other Brazilian Taxes

There are no Brazilian inheritance, gift or succession taxes applicable to the ownership, transfer or disposition of preferred or common shares or ADSs by a non-Brazilian holder, except for gift and inheritance taxes which are levied by certain states of Brazil on gifts made or inheritances bestowed by a non-Brazilian holder to individuals or entities resident or domiciled within such states in Brazil. There are no Brazilian stamp, issue, registration, or similar taxes or duties payable by holders of preferred or common shares or ADSs.

Registered Capital

The amount of an investment in preferred or common shares held by a non-Brazilian holder who obtains registration under Resolution No. 2,689, or by the depositary representing such holder, is eligible for registration with the Central Bank of Brazil; such registration (the amount so registered being called registered capital) allows the remittance outside Brazil of foreign currency, converted at the commercial market rate, acquired with the proceeds of distributions on, and amounts realized with respect to dispositions of, such preferred or common shares.  The registered capital for each preferred or common share purchased as part of the international offering or purchased in Brazil after the date hereof, and deposited with the depositary will be equal to its purchase price (in U.S. dollars).  The registered capital for a preferred or common share that is withdrawn upon surrender of an ADS will be the U.S. dollar equivalent of:

(a)   the average price of a preferred or common share on the Brazilian stock exchange on which the greatest number of such shares were sold on the day of withdrawal; or

(b)   if no preferred or common shares were sold on that day, the average price on the Brazilian stock exchange on which the greatest number of preferred or common shares were sold in the 15 trading sessions immediately preceding such withdrawal.

The U.S. dollar value of the average price of preferred or common shares is determined on the basis of the average of the U.S. dollar/real commercial market rates quoted by the Central Bank of Brazil information system on that date (or, if the average price of preferred or common shares is determined under the second option above, the average of such average quoted rates on the same 15 dates used to determine the average price of preferred or common shares).

163

A non-Brazilian holder of preferred or common shares may experience delays in effecting such registration, which may delay remittances abroad. Such a delay may adversely affect the amount, in U.S. dollars, received by the non-Brazilian holder.  See Item 3. “Key Information—Risk Factors—Risks Relating to Our Equity and Debt Securities.”

U.S. Federal Income Tax Considerations

This summary describes the principal U.S. federal income tax consequences of the ownership and disposition of common or preferred shares or ADSs, based on the U.S. Internal Revenue Code of 1986, as amended (the Code), its legislative history, existing and proposed U.S. Treasury regulations promulgated thereunder, published rulings by the U.S. Internal Revenue Service (IRS), and court decisions, all as in effect as of the date hereof, and all of which are subject to change or differing interpretations, possibly with retroactive effect. This summary does not purport to be a comprehensive description of all of the tax consequences that may be relevant to a decision to hold or dispose of common or preferred shares or ADSs. This summary applies only to purchasers of common or preferred shares or ADSs who hold the common or preferred shares or ADSs as “capital assets” (generally, property held for investment), and does not apply to special classes of holders such as dealers or traders in securities or currencies, holders whose functional currency is not the U.S. dollar, holders of 10% or more of our shares (taking into account shares held directly or through depositary arrangements), tax-exempt organizations, partnerships or partners therein, financial institutions, holders liable for the alternative minimum tax, securities traders who elect to account for their investment in common or preferred shares or ADSs on a mark-to-market basis, persons that enter into a constructive sale transaction with respect to common or preferred shares or ADSs, and persons holding common or preferred shares or ADSs in a hedging transaction or as part of a straddle or conversion transaction.

EACH HOLDER SHOULD CONSULT ITS OWN TAX ADVISOR CONCERNING THE OVERALL TAX CONSEQUENCES IN ITS PARTICULAR CIRCUMSTANCES, INCLUDING THE CONSEQUENCES UNDER LAWS OTHER THAN U.S. FEDERAL INCOME TAX LAWS, OF AN INVESTMENT IN COMMON OR PREFERRED SHARES OR ADSs.

Shares of our preferred stock will be treated as equity for U.S. federal income tax purposes. In general, a holder of an ADS will be treated as the holder of the shares of common or preferred stock represented by those ADSs for U.S. federal income tax purposes, and no gain or loss will be recognized if you exchange ADSs for the shares of common or preferred stock represented by that ADS.

In this discussion, references to ADSs refer to ADSs with respect to both common and preferred shares, and references to a “U.S. Holder” are to a holder of an ADS that is:

•an individual who is a citizen or resident of the United States;

•a corporation organized under the laws of the United States, any state thereof, or the District of Columbia; or

•otherwise subject to U.S. federal income taxation on a net basis with respect to the shares or the ADS.

164

Taxation of Distributions

A U.S. Holder will recognize ordinary dividend income for U.S. federal income tax purposes in an amount equal to the amount of any cash and the value of any property we distribute as a dividend to the extent that such distribution is paid out of our current or accumulated earnings and profits, as determined for U.S. federal income tax purposes, when such distribution is received by the custodian, or by the U.S. Holder in the case of a holder of common or preferred shares. The amount of any distribution will include distributions characterized as interest on shareholders’ equity and the amount of Brazilian tax withheld on the amount distributed, and the amount of a distribution paid in reais  will be measured by reference to the exchange rate for converting reais  into U.S. dollars in effect on the date the distribution is received by the custodian, or by a U.S. Holder in the case of a holder of common or preferred shares. If the custodian, or U.S. Holder in the case of a holder of common or preferred shares, does not convert such reais  into U.S. dollars on the date it receives them, it is possible that the U.S. Holder will recognize foreign currency loss or gain, which would be U.S. source ordinary loss or gain, when the reais  are converted into U.S. dollars. Dividends paid by us will not be eligible for the dividends received deduction allowed to corporations under the Code.

Subject to certain exceptions for short-term and hedged positions, the U.S. dollar amount of dividends received by a non-corporate U.S. Holder prior to January 1, 2013, with respect to the ADSs will be subject to taxation at a maximum rate of 15% if the dividends are “qualified dividends.” Dividends paid on the ADSs will be treated as qualified dividends if (i) the ADSs are readily tradable on an established securities market in the United States and (ii) the Company was not, in the year prior to the year in which the dividend was paid, and is not, in the year in which the dividend is paid, a “passive foreign investment company” as defined for U.S. federal income tax purposes (a PFIC). The ADSs are listed on the New York Stock Exchange, and will qualify as readily tradable on an established securities market in the United States so long as they are so listed. Based on the Company’s audited financial statements and relevant market and shareholder data, the Company believes that it should not be treated as a PFIC for U.S. federal income tax purposes with respect to its 2010 taxable year. In addition, based on the Company’s audited financial statements and its current expectations regarding the value and nature of its assets, the sources and nature of its income, and relevant market and shareholder data, the Company does not anticipate becoming a PFIC for its 2011 taxable year. Based on existing guidance, it is not clear whether dividends received with respect to the shares will be treated as qualified dividends, because the shares are not themselves listed on a U.S. exchange. In addition, the U.S. Treasury has announced its intention to promulgate rules pursuant to which holders of ADSs and intermediaries through whom such securities are held will be permitted to rely on certifications from issuers to treat dividends as qualified for tax reporting purposes. Because such procedures have not yet been issued, it is not clear whether the Company would be able to comply with these procedures. U.S. Holders of our ADSs should consult their own tax advisors regarding the availability of the reduced dividend tax rate in the light of their particular circumstances.

Distributions out of earnings and profits with respect to the shares or ADSs generally will be treated as dividend income from sources outside of the United States and generally will be treated as “passive category income” for U.S. foreign tax credit purposes. Subject to certain limitations, Brazilian income tax withheld in connection with any distribution with respect to the shares or ADSs may be claimed as a credit against the U.S. federal income tax liability of a U.S. Holder, or, at the U.S. Holder’s election, such Brazilian withholding tax may be taken as a deduction against taxable income. A U.S. foreign tax credit may not be allowed for Brazilian withholding tax imposed in respect of certain short-term or hedged positions in securities or in respect of arrangements in which a U.S. Holder’s expected economic profit is insubstantial. U.S. Holders should consult their own tax advisors regarding the availability of the U.S. foreign tax credit, including the translation of reais  into U.S. dollar for these purposes, in light of their particular circumstances.

Holders of ADSs that are foreign corporations or nonresident alien individuals (non-U.S. Holders) generally will not be subject to U.S. federal income tax, including withholding tax, on distributions with respect to shares or ADSs that are treated as dividend income for U.S. federal income tax purposes unless such dividends are effectively connected with the conduct by the holder of a trade or business in the United States.

Holders of shares and ADSs should consult their own tax advisers regarding the availability of the reduced dividend tax rate in the light of the considerations discussed above and their own particular circumstances.

165

Taxation of Capital Gains

Upon the sale or other disposition of a share or an ADS, a U.S. Holder will generally recognize U.S. source capital gain or loss for U.S. federal income tax purposes, equal to the difference between the amount realized on the disposition and the U.S. Holder’s tax basis in such share or ADS. Any gain or loss will be long-term capital gain or loss if the shares or ADSs have been held for more than one year. Non-corporate U.S. Holders of shares or ADSs may be eligible for a preferential rate of U.S. federal income tax in respect of long-term capital gains. Capital losses may be deducted from taxable income, subject to certain limitations. For U.S. federal income tax purposes, such disposition would not result in foreign source-income to a U.S. Holder. As a result, a U.S. Holder may not be able to use the foreign tax credit associated with any Brazilian income taxes imposed on such gains, unless such holder can use the credit against U.S. tax due on other foreign-source income. U.S. Holders should consult their own tax advisors regarding the availability of the U.S. foreign tax credit, including the translation of reais  into U.S. dollar for purposes of their investment in our shares or ADSs.

A non-U.S. Holder will not be subject to U.S. federal income tax or withholding tax on gain realized on the sale or other disposition of a share or an ADS, unless:

•such gain is effectively connected with the conduct by the holder of a trade or business in the United States; or

•such holder is an individual who is present in the United States for 183 days or more in the taxable year of the sale and certain other conditions are met.

Information Reporting and Backup Withholding

The payment of dividends on, and proceeds from the sale or other disposition of, the ADSs or common or preferred shares to a U.S. Holder within the United States (or through certain U.S. related financial intermediaries) will generally be subject to information reporting unless the U.S. Holder is a corporation or other exempt recipient. Such dividends and proceeds may be subject to backup withholding unless the U.S. Holder (i) is an exempt recipient, or (ii) timely provides a taxpayer identification number and certifies that no loss of exemption from backup withholding has occurred. Backup withholding is not an additional tax. 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, so long as the required information is properly furnished to the IRS.

U.S. Holders should consult their own tax advisors about any additional reporting requirements that may arise as a result of their purchasing, holding or disposing of our ADSs, or common or preferred shares.

A non-U.S. Holder generally will be exempt from these information reporting requirements and backup withholding tax, but may be required to comply with certain certification and identification procedures in order to establish its eligibility for such exemption.

Taxation Relating to PifCo’s Notes

The following summary contains a description of material Cayman Islands, Brazilian and U.S. federal income tax considerations that may be relevant to the purchase, ownership, and disposition of PifCo’s debt securities.  This summary does not describe any tax consequences arising under the laws of any state, locality or taxing jurisdiction other than the Cayman Islands, Brazil and the United States.

This summary is based on the tax laws of the Cayman Islands, Brazil and the United States as in effect on the date of this annual report, which are subject to change (possibly with retroactive effect).  This description is not a comprehensive description of all tax considerations that may be relevant to any particular investor, including tax considerations that arise from rules generally applicable to all taxpayers or to certain classes of investors or that investors are generally assumed to know.  Prospective purchasers of notes should consult their own tax advisors regarding the tax consequences of the acquisition, ownership and disposition of the notes.

166

There is no tax treaty to avoid double taxation between the Cayman Islands and the United States, the Cayman Islands and Brazil or Brazil and the United States. In recent years, the tax authorities of Brazil and the United States have held discussions that may culminate in such a treaty.  We cannot predict, however, whether or when a treaty will enter into force or how it will affect the U.S. Holders of notes.

Cayman IslandsTaxation 

Under current law, PifCo is not subject to income, capital, transfer, sales or other taxes in the Cayman Islands.

PifCo was incorporated as an exempted company under the laws of the Cayman Islands on September 24, 1997.  PifCo has received an Undertaking as to Tax Concessions pursuant to Section 6 of the Tax Concessions Law (1999 Revision) which provides that, for a period of twenty years from the date thereof no law hereafter enacted in the Cayman Islands imposing any tax or duty to be levied on income or on capital assets, gains or appreciation will apply to any of PifCo’s income or property and which is deemed to provide that no tax is to be levied on profits, income, gains or appreciations or which is in the nature of estate duty or inheritance tax shall be payable or in respect of shares, debentures or other of PifCo’s obligations, or by way of withholding of any part of a payment of principal due under a debenture or other of PifCo’s obligations.

No Cayman Islands withholding tax applies to distributions by PifCo in respect of the notes.  Noteholders are not subject to any income, capital, transfer, sales or other taxes in the Cayman Islands in respect of their purchase, holding or disposition of the notes.

Noteholders whose notes are brought into or issued in the Cayman Islands will be liable to pay stamp duty of up to C.I.$250 on each note, unless stamp duty of C.I.$500 has been paid in respect of the entire issue of notes (in which case no further stamp duty in respect of such notes is payable).

Brazilian Taxation

The following discussion is a summary of the Brazilian tax considerations relating to an investment in the notes by a non-resident of Brazil.  The discussion is based on the tax laws of Brazil as in effect on the date hereof 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 consequences relating to an investment in the notes.

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, REDEMPTION OR REPAYMENT OF THE NOTES OR COUPONS.

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

Interest, fees, commissions, expenses and any other income payable by Petrobras as guarantor resident in Brazil to a Non-resident are generally subject to income tax withheld at source.  The rate of withholding income tax in respect of interest payments is generally 15%, unless (i) the holder of the notes is resident or domiciled in a “tax haven jurisdiction” (that is deemed to be a country or jurisdiction which does not impose any tax on income or which imposes such tax at a maximum effective rate lower than 20% or where the local legislation imposes restrictions on disclosing the identities of shareholders, the ownership of investments, or the ultimate beneficiary of earnings distributed to the Non-resident— “tax haven 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 another 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 at the rate of up to 25% as described above.  Although Brazilian legislation does not provide a specific tax rule for such cases and there is no official position from tax authorities or precedents from the Brazilian court regarding the matter, we believe that the remittance of funds by Petrobras as a guarantor for the payment of the principal amount of the notes will not be subject to income tax in Brazil, because the mere fact that the guarantor is making the payment does not convert the nature of the principal due under the notes into income of the beneficiary.

167

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

Gains on the sale or other disposition of the notes made outside of Brazil by a Non-resident, other than a branch or a subsidiary of Brazilian resident, to another Non-resident are not subject to Brazilian income tax.

In addition, payments made from Brazil are subject to the tax on foreign exchange transactions (IOF/Câmbio), which is levied on the conversion of Brazilian currency into foreign currency and on the conversion of foreign currency into Brazilian currency at a general rate of 0.38%.  Other IOF/Câmbio rates may apply to specific transactions. In any case, the Brazilian federal government may increase, at any time, such rate up to 25% but only with respect to future transactions.

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

U.S. Federal Income Taxation

The following summary sets forth certain United States federal income tax considerations that may be relevant to a holder of a note that is, for U.S. federal income purposes, a citizen or resident of the United States or a domestic corporation or that otherwise is subject to U.S. federal income taxation on a net income basis in respect of the notes (a “U.S. Holder”). This summary is based upon the Code, its legislative history, existing and proposed U.S. Treasury regulations promulgated thereunder, published rulings by the IRS, and court decisions, all as in effect as of the date hereof, all of which are subject to change or differing interpretations, possibly with retroactive effect. This summary does not purport to discuss all aspects of the United States federal income taxation which may be relevant to special classes of investors, such as financial institutions, insurance companies, dealers or traders in securities or currencies, securities traders who elect to account for their investment in notes on a mark-to-market basis, regulated investment companies, tax-exempt organizations, partnerships or partners therein, holders that are subject to the alternative minimum tax, certain short-term holders of notes, persons that hedge their exposure in the notes or hold notes as part of a position in a “straddle” or as part of a hedging transaction or “conversion transaction” for U.S. federal tax purposes, persons that enter into a “constructive sale” transaction with respect to the notes or U.S. Holder whose functional currency is not the U.S. dollar.  U.S. Holders should be aware that the U.S. federal income tax consequences of holding the notes may be materially different for investors described in the prior sentence.

In addition, this summary does not discuss any foreign, state or local tax considerations.  This summary only applies to original purchasers of notes who have purchased notes at the original issue price and hold the notes as “capital assets” (generally, property held for investment).

EACH HOLDER SHOULD CONSULT ITS OWN TAX ADVISOR CONCERNING THE OVERALL TAX CONSEQUENCES IN ITS PARTICULAR CIRCUMSTANCES, INCLUDING THE CONSEQUENCES UNDER LAWS OTHER THAN U.S. FEDERAL INCOME TAX LAWS, OF AN INVESTMENT IN THE NOTES.

168

Payments of Interest

Payment of “qualified stated interest,” as defined below, on a note (including additional amounts, if any) 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 applicable method of accounting for U.S. federal tax purposes.  In general, if the “issue price” of a note is less than the “stated redemption price at maturity” by more than a de minimis amount, such note will be considered to have “original issue discount,” or OID.  The “issue price” of a note is the first price at which a substantial amount of such notes are sold to investors. The stated redemption price at maturity of a note generally includes all payments other than payments of qualified stated interest.

In general, each U.S. Holder of a note, whether such holder uses the cash or the accrual method of tax accounting, will be required to include in gross income as ordinary interest income the sum of the “daily portions” of OID on the note, if any, for all days during the taxable year that the U.S. Holder owns the note.  The daily portions of OID on a note are determined by allocating to each day in any accrual period a ratable portion of the OID allocable to that accrual period.  In general, in the case of an initial holder, the amount of OID on a note allocable to each accrual period is determined by (i) multiplying the “adjusted issue price,” as defined below, of the note at the beginning of the accrual period by the yield to maturity of the note, and (ii) subtracting from that product the amount of qualified stated interest allocable to that accrual period. U.S. Holders should be aware that they generally must include OID in gross income as ordinary interest income for U.S. federal income tax purposes as it accrues, in advance of the receipt of cash attributable to that income.  The “adjusted issue price” of a note at the beginning of any accrual period will generally be the sum of its issue price (generally including accrued interest, if any) and the amount of OID allocable to all prior accrual periods, reduced by the amount of all payments other than payments of qualified stated interest (if any) made with respect to such note in all prior accrual periods. The term “qualified stated interest” generally means stated interest that is unconditionally payable in cash or property (other than debt instruments of the issuer) at least annually during the entire term of a note at a single fixed rate of interest, or subject to certain conditions, based on one or more interest indices.

Interest income, including OID, in respect of the notes will constitute foreign source income for U.S. federal income tax purposes and, with certain exceptions, will be treated separately, together with other items of “passive category income,” for purposes of computing the foreign tax credit allowable under the U.S. federal income tax laws.  The calculation of foreign tax credits, involves the application of complex rules that depend on a U.S. Holder’s particular circumstances.  U.S. Holders should consult their own tax advisors regarding the availability of foreign tax credits and the treatment of additional amounts.

Saleor Disposition of Notes

A U.S. Holder generally will recognize capital gain or loss upon the sale, exchange, retirement or other disposition of a note in an amount equal to the difference between the amount realized upon such sale, exchange, retirement or other disposition (other than amounts attributable to accrued qualified stated interest, which will be taxed as such) and such U.S. Holder’s adjusted tax basis in the note.  A U.S. Holder’s adjusted tax basis in the note generally will equal the U.S. Holder’s cost for the note increased by any amounts included in gross income by such U.S. Holder as OID, if any, and reduced by any payments other than payments of qualified stated interest on that note.  Gain or loss realized by a U.S. Holder on the sale, exchange, retirement or other disposition of a note generally will be U.S. source gain or loss for U.S. federal income tax purposes unless it is attributable to an office or other fixed place of business outside the United States and certain other conditions are met.  The gain or loss realized by a U.S. Holder will be capital gain or loss, and will be long-term capital gain or loss if the notes were held for more than one year.  The net amount of long-term capital gain recognized by an individual holder before January 1, 2013 generally is subject to taxation at a maximum rate of 15%.  Capital losses may be deducted from taxable income, subject to certain limitations.

169

Backup Withholding and Information Reporting

A U.S. Holder may, under certain circumstances, be subject to “backup withholding” with respect to certain payments to that U.S. Holder, unless the holder (i) is an 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.  Any amount withheld under these rules generally will be creditable against the U.S. Holder’s U.S. federal income tax liability.  While non-U.S. Holders generally are except from backup withholding, a non-U.S. Holder may, in certain circumstances, be required to comply with certain information and identification procedures in order to prove entitlement to this exemption.

U.S. Holders should consult their own tax advisors about any additional reporting requirements that may arise as a result of their purchasing, holding or disposing of the notes.

Non-U.S. Holder

A holder or beneficial owner of a note that is not a U.S. Holder (a “non-U.S. Holder”) generally will not be subject to U.S. federal income or withholding tax on interest received on the notes.  In addition, a non-U.S. Holder will not be subject to U.S. federal income or withholding tax on gain realized on the sale of notes unless such gain is effectively connected with the conduct by such holder of a trade or business in the United States or, in the case of gain realized by an individual non-U.S. Holder, the non-U.S. Holder is present in the United States for 183 days or more in the taxable year of the sale and certain other conditions are met.

Item 11.                Qualitative and Quantitative Disclosures about Market Risk

Petrobras

Risk Management

We are exposed to a number of market and credit risks arising from our normal business activities.  Market risk is the possibility that changes in interest rates, currency exchange rates or commodity prices will adversely affect the value of our financial assets, liabilities or expected future cash flows.  Credit risk is the failure of a counterparty to perform a payment obligation under a commercial contract or a derivative contract.

We use derivative instruments to address market risks related to commodity prices, interest rates and currency exchange rates.  Such derivative instruments are used to offset market exposures.  Our executive officers manage market risk.  We address credit risk by following rigid rules, overseen by a Credit Committee, to evaluate counterparties and define proper guaranties.

In March 2010, as a result of our adoption of a new corporate governance model, the board of executive officers conferred the mandate of the Risk Management Committee to the newly-created Financial Committee.  The Financial Committee, comprised of executive managers from our different business areas, evaluates our risk exposures and establishes guidelines that we use to measure, monitor and manage risk related to our activities and operations.

Commodity Price Risk

Our sales of crude oil and oil products are related to international prices, which exposes us to price fluctuations in international markets.

We enter into derivative transactions, primarily energy futures contracts, forwards, swaps, and options, in order to mitigate some of the impact of such fluctuations.  Our derivatives contracts provide economic hedges for anticipated crude oil and byproducts purchases and sales in the international markets, generally forecast to occur within a 30- to 360-day period.  Our exposure on these contracts is limited to the difference between contract value and market value on the volumes hedged. See Note 19 to our audited consolidated financial statements for more information about our commodity derivative transactions. 

171

The following table sets forth a sensitivity analysis demonstrating the net change in fair value of a 10% adverse change in the price of the underlying commodity as of December 31, 2010, which is a 10% increase in the price of the underlying commodity for options, futures and swaps.

(1)      Fair value represents an estimate of gain or loss that would be realized if contracts were settled at the balance sheet date.

Interest Rate and Exchange Rate Risk

The interest rate risk to which we are exposed is a function of our long-term debt and, to a lesser extent, our short-term debt.  Our long-term debt consists principally of notes and borrowings incurred primarily in connection with capital expenditures and investments in exploration and development projects and loans to affiliated companies.  Our short-term debt consists principally of U.S. dollar denominated import and export financing and working capital borrowings from commercial banks.  In general, our foreign currency floating rate debt is principally subject to fluctuations in LIBOR.  Our floating rate debt denominated in reais is principally subject to fluctuations in the Certificado de Depósito Interbancário (Interbank Deposit Certificate, or CDI) and in the Taxa de Juros de Longo Prazo (Brazilian long-term interest rate, or TJLP), as fixed by the CMN.

We do not currently utilize derivative instruments to manage our exposure to interest rate fluctuation.  We have been considering various forms of derivatives to reduce our exposure to interest rate fluctuations and may utilize these financial instruments in the future.

The exchange rate risk to which we are exposed is limited to the balance sheet and derives principally from the incidence of non-real denominated obligations in our debt portfolio.  See Item 5. “Operating and Financial Review and Prospects—Inflation and Exchange Rate Variation.”

172

The table below provides summary information regarding our exposure to interest rate and exchange rate risk in our total debt portfolio for 2010 and 2009.  Total debt portfolio includes long-term debt, capital leases, project financings, and current portions thereof, and short-term debt.

Our foreign currency risk management strategy includes the use of derivative instruments to protect against foreign exchange rate volatility, which may impact the value of certain of our obligations.

PifCo

PifCo faces market risks in the normal course of business, including interest rate risk, risk related to changes in oil and oil products prices, and risk related to changes in foreign exchange rates.  PifCo makes limited use of derivatives to manage its exposure to these market risks.  PifCo does not hold derivative instruments for trading purposes.

Commodity Price Risk

PifCo enters into derivative transactions in order to mitigate the impact of fluctuations in the price of crude oil and byproducts.  PifCo uses futures contracts, swaps and options to protect its margins in anticipation of purchases and sales in the international markets, as shown in the sensitivity analysis above.

174

Interest Rate and Exchange Rate Risk

PifCo is not subject to material foreign exchange rate risk because 100% of its debt is U.S. dollar denominated.  PifCo does not enter into derivative contracts or make other arrangements to hedge against interest rate risk.

The table below sets forth the amounts and related weighted average annual interest rates by expected maturity dates for PifCo’s long-term debt obligations at December 31, 2010:

Item 15.                Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Both PifCo and we have evaluated, with the participation of our Chief Executive Officer and Chief Financial Officer, the effectiveness of our disclosure controls and procedures as of December 31, 2010.  There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures.  Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives. Based upon our evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures as of December 31, 2010 were effective to provide reasonable assurance that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the applicable rules and forms, and that it is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Management’s Report on Internal Control over Financial Reporting

The managements of Petróleo Brasileiro S.A.—Petrobras and Petrobras International Finance Company—PifCo (each, a “Company”) are responsible for establishing and maintaining effective internal control over financial reporting and for their assessments of the effectiveness of internal control over financial reporting.

Each Company’s internal control over financial reporting is a process designed by, or under the supervision of Petrobras’ Audit Committee and each of the Company’s Chief Executive Officer, Chief Financial Officer and effected by each Company’s board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external purposes in accordance with U.S. GAAP.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements on a timely basis.  Therefore even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.  Also, projections of any evaluation of the effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Each of the Company’s management assessed the effectiveness of each Company’s internal control over financial reporting as of December 31, 2010, based on the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).  Based on that assessment, each of the Company’s management has concluded that as of December 31, 2010, each Company’s internal control over financial reporting is effective.

The effectiveness of each of the Company’s internal control over financial reporting as of December 31, 2010, has been audited by KPMG Auditores Independentes, an independent registered public accounting firm, as stated in their report which appears herein.

177

Changes in Internal Controls

The management of each Company identified no change in its internal control over financial reporting during the fiscal year ended December 31, 2010, that has materially affected or is reasonably likely to materially affect its internal control over financial reporting.

Item 16A.             Audit Committee Financial Expert

On June 17, 2005, our board of directors approved the appointment of an audit committee for purposes of the Sarbanes-Oxley Act of 2002.  Our board of directors has determined that Fabio Colletti Barbosa is the audit committee financial expert, and he is independent, as defined in 17 CFR 240.10A-3.

PifCo’s board of directors currently serves as its audit committee for purposes of the Sarbanes-Oxley Act of 2002.  PifCo’s board of directors has determined that Marcos Antonio Silva Menezes is an “audit committee financial expert” within the meaning of this Item 16A.  Mr. Menezes is not independent as defined in 17 CFR 240.10A-3.

Item 16B.              Code of Ethics

We have always guided our business and our relations with third parties by strong ethical principles.  In 1998, our board of executive officers approved the Petrobras Code of Ethics, which was extended to all Petrobras companies in 2002, and renamed Petrobras System’s Code of Ethics.

In 2006, after undergoing a revision process with wide participation from our business segments, employees and subsidiaries, the Code of Ethics was approved by the board of executive officers and the board of directors.  Our board of executive officers further developed our ethics management through the creation of the Petrobras Ethics Commission in 2008.  The Code of Ethics is applicable to all employees and the members of the board of executive officers and the board of directors.  The document is available on our website at http://www.petrobras.com.br/en/investors.  It is the responsibility of the Ethics Commission to promote compliance with ethical principles and act as a forum for discussion of subjects related to ethics.  Currently, the Commission’s focus is to develop and strengthen the Petrobras Ethics Management System, which is aimed at assuring the highest ethics standards by defining the roles of managers, employees, the Ethics Commission and their relationships.

The following table sets forth the fees billed to PifCo by its independent auditors KPMG Auditores Independentes, during the fiscal years ended December 31, 2010 and 2009:

	Year Ended December 31,
	2010	2009
	(U.S.$ thousand)
Audit fees	540	404
Audit-related fees	36	29
Total fees	576	433

Audit fees in the above table are the aggregate fees billed by KPMG Auditores Independentes in connection with the audit of PifCo’s annual financial statements (U.S. GAAP and Brazilian GAAP), interim reviews (U.S. GAAP and Brazilian GAAP), subsidiary audits (U.S. GAAP and local GAAP) and review of periodic documents filed with the SEC.  In 2010, audit fees include the aggregate fees billed by KPMG Auditores Independentes, in the amount of U.S.$36 thousand, related to the audit of the internal controls.  Fees disclosed under the category “audit-related fees” relate to services provided in connection with the issuance of PifCo’s notes in the international capital markets and assurance and related services that are reasonably related to the performance of the audit or reviews of PifCo’s financial statements and are not reported under “audit fees.”

PifCo’s contract with KPMG Auditores Independentes was signed in 2006 and, pursuant to a renewal of this contract, KPMG Auditores Independentes will audit PifCo’s financial statements through year-end December 31, 2011.

Audit Committee Approval Policies and Procedures

Our audit committee has the authority to recommend pre-approval policies and procedures to our board of directors for the engagement of our or PifCo’s independent auditor for services.  At present, our board of directors has decided not to establish such pre-approval policies and procedures.  Our board of directors expressly approves on a case-by-case basis any engagement of our independent auditors for all services provided to our subsidiaries or to us.  Our bylaws prohibit our independent auditor from providing any consulting services to our subsidiaries or to us during the term of such auditor’s contract.

Item 16D.             Exemptions from the Listing Standards for Audit Committees

Under the listed company audit committee rules of the NYSE and the SEC, we must comply with Exchange Act Rule 10A-3, which requires that we establish an audit committee composed of members of the board of directors that meets specified requirements.  In reliance on the exemption in Rule 10A-3(b)(iv)(E), we have designated two members to our audit committee, Francisco Roberto de Albuquerque and Sergio Franklin Quintella, who are designees of the Brazilian federal government, which is our principal shareholder and therefore one of our affiliates.  In our assessment, each of these members acts independently in performing the responsibilities of an audit committee member under the Sarbanes-Oxley Act and satisfy the other requirements of Exchange Act Rule 10A-3.

Item 16E.              Purchases of Equity Securities by the Issuer and Affiliated Purchasers

Petrobras

During the fiscal year ended December 31, 2010, neither any “affiliated purchaser,” as defined in Rule 10b-18(a)(3) under the Securities Exchange Act, nor we have purchased any of our equity securities.

Item 16F.              Change in Registrant’s Certifying Accountant

Not applicable.

Item 16G.             Corporate Governance

Comparison of Petrobras’ Corporate Governance Practices with NYSE Corporate Governance Requirements Applicable to U.S. Companies

Under the rules of the New York Stock Exchange, foreign private issuers are subject to a more limited set of corporate governance requirements than U.S. domestic issuers.  As a foreign private issuer, we must comply with four principal NYSE corporate governance rules:  (i) we must satisfy the requirements of Exchange Act Rule 10A-3; (ii) our Chief Executive Officer must promptly notify the NYSE in writing after any executive officer becomes aware of any material non-compliance with the applicable NYSE corporate governance rules; (iii) we must provide the NYSE with annual and interim written affirmations as required under the NYSE corporate governance rules; and (iv) we must provide a brief description of any significant differences between its corporate governance practices and those followed by U.S. companies under NYSE listing standards.

180

The table below briefly describes the significant differences between our domestic practices and the NYSE corporate governance rules.

Section	New York Stock Exchange Corporate GovernanceRules for U.S. Domestic Issuers	Petrobras’ Practices
Director Independence
303A.01	Listed companies must have a majority of independent directors. “Controlled companies” are not required to comply with this requirement.	Petrobras is a controlled company because more than a majority of its voting power is controlled by the Brazilian Federal Government.  As a controlled company, Petrobras would not be required to comply with the majority of independent directors requirement if it were a U.S. domestic issuer.  There is no legal provision or policy that requires us to have independent directors.
303A.03	The non-management directors of each listed company must meet at regularly scheduled executive sessions without management.	With the exception of the CEO of the company (who is also a director), all of Petrobras’ directors are non-management directors. These non-management directors do not meet at regularly scheduled executive sessions without the presence of the CEO.
Nominating/Corporate Governance Committee
303A.04	Listed companies must have a nominating/corporate governance committee composed entirely of independent directors, with a written charter that covers certain minimum specified duties. “Controlled companies” are not required to comply with this requirement.	Petrobras does not have a nominating committee. Petrobras also does not have a corporate governance committee composed of directors. Petrobras’ board of directors develops, evaluates and approves corporate governance principles.  As a controlled company, Petrobras would not be required to comply with the nominating/corporate governance committee requirement if it were a U.S. domestic issuer.
Compensation Committee
303A.05	Listed companies must have a compensation committee composed entirely of independent directors, with a written charter that covers certain minimum specified duties. “Controlled companies” are not required to comply with this requirement.	Petrobras has a committee that advises the board of directors with respect to compensation and management succession.  There is no legal provision or policy that requires the members of this committee to be independent. As a controlled company, Petrobras would not be required to comply with the compensation committee requirement if it were a U.S. domestic issuer.
Audit Committee
303A.06 303A.07	Listed companies must have an audit committee with a minimum of three independent directors that satisfy the independence requirements of Rule 10A-3 under the Exchange Act, with a written charter that covers certain minimum specified duties.	Petrobras’ Audit Committee is an advisory committee to the board of directors and is composed of independent members according to Rule 10A-3 under the Exchange Act. The Audit Committee has a written charter that sets forth its responsibilities that include, among other things: (i) strengthening ties with the external auditors, permitting closer supervision of their work and of issues regarding their competency and independence, (ii) assuring legal and regulatory compliance, including with regard to certification, internal controls, compliance procedures and ethics, and (iii) monitoring the financial position of the company, especially as to risks, internal auditing work and financial disclosure.
Equity Compensation Plans
303A.08	Shareholders must have the opportunity to vote for compensation plans through shares and material reviews, with limited exceptions as set forth by the NYSE’s rules.	Under the Brazilian Corporate Law, shareholder approval is required for the adoption and revision of any equity compensation plans. Petrobras does not currently have any equity compensation plans.
Corporate Governance Guidelines
303A.09	Listed companies must adopt and disclose corporate governance guidelines.	Petrobras has a set of Corporate Governance Guidelines (Diretrizes de Governança Corporativa) that address director qualification standards, responsibilities, compensation, orientation, self-appraisals and access to management. The guidelines do not reflect the independence requirements set forth in Sections 303A.01 and .02 of the NYSE rules. Certain portions of the guidelines, including the responsibilities and compensation sections, are not discussed with the same level of detail set forth in the commentaries to the NYSE rules. The guidelines are available on Petrobras’ website.
Code of Ethics for Directors, Officers and Employees
303A.10	Listed companies must adopt and disclose a code of business conduct and ethics for directors, officers and employees, and promptly disclose any waivers of the code for directors or executive officers.	Petrobras has adopted a Code of Ethics (Código de Ética) applicable to its employees and a Code of Good Practices (Código de Boas Práticas) applicable to directors and executive officers. No waivers of the provisions of the Code of Ethics or Code of Good Practices are permitted. Both documents are available on Petrobras’ website.
Certification Requirements
303A.12	Each listed company CEO must certify to the NYSE each year that he or she is not aware of any violation by the company of NYSE corporate governance listing standards.	Our CEO will promptly notify the NYSE in writing if any executive officer becomes aware of any material noncompliance with any applicable provisions of the NYSE corporate governance rules.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of
Petróleo Brasileiro S.A. - Petrobras

We have audited the accompanying consolidated balance sheets of Petróleo Brasileiro S.A. -Petrobras and subsidiaries (the “Company”) as of December 31, 2010 and 2009, and the related consolidated statements of income, changes in shareholders’ equity and cash flows for each of the years in the three-year period ended December 31, 2010. We also have audited the Company’s internal control over financial reporting as of December 31, 2010, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on these consolidated financial statements and an opinion on the Company’s internal control over financial reporting based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the consolidated financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall consolidated financial statements presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Table of Contents

A Company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the consolidated financial statements for external purposes in accordance with generally accepted accounting principles. A Company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of consolidated financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Company’s assets that could have a material effect on the consolidated financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Petróleo Brasileiro S.A. – Petrobras and subsidiaries as of December 31, 2010 and 2009, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2010, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, Petróleo Brasileiro S.A. - Petrobras and subsidiaries maintained, in all material respects, effective internal control over financial reporting as of December 31, 2010, based on criteria established in COSO.

2. Summary of Significant Accounting Policies (Continued)

a) Basis of financial statements preparation

The accompanying consolidated financial statements of Petróleo Brasileiro S.A. - Petrobras (the Company) have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) and the rules and regulations of the Securities and Exchange Commission (SEC). U.S. GAAP differs in certain respects from International Financial Reporting Standards (IFRS), as issued by International Financial Reporting Standards Board (IASB) and applied by Petrobras in its statutory financial statements prepared in accordance with Brazilian Corporate Law and regulations promulgated by the Brazilian Securities and Exchange Commission (CVM). The Brazilian Corporation Law was amended in 2007 to permit Brazilian GAAP to converge with International Financial Reporting Standards, and Petrobras chose to present its financial statements for local purposes for the first time in accordance with IFRS in the first quarter of 2010 (see more details in Note 2 - item p).

The U.S. dollar amounts for the years presented have been translated from the Brazilian Real amounts in accordance Accounting Standard Codification – ASC Topic 830 – Foreign Currency Matters as applicable to entities operating in non-hyperinflationary economies. Transactions occurring in foreign currencies are first remeasured to the Brazilian Real and then translated to the U.S. dollar, with remeasurement gains and losses being recognized in the statements of income. While Petrobras has selected the U.S. Dollar as its reporting currency, the functional currency of Petrobras and all Brazilian subsidiaries is the Brazilian Real. The functional currency of Petrobras International Finance Company – PifCo and some subsidiaries and certain of the special purpose companies that operate in the international economic environment is the U.S. dollar, and the functional currency of Petrobras Argentina is the Argentine Peso.

The Company has translated all assets and liabilities into U.S. dollars at the current exchange rate (R$1.666 and R$1.741 to US$1.00 at December 31, 2010 and 2009, respectively), and all accounts in the statements of income and cash flows (including amounts relative to local currency indexation and exchange variances on assets and liabilities denominated in foreign currency) at the average rates prevailing during the year. The net translation gain in the amount of US$6,796 in 2010 (net translation gain in 2009 - US$22,589 and net translation loss in 2008 - US$20,001) resulting from this remeasurement process was excluded from income and presented as a cumulative translation adjustment (“CTA”) within “Accumulated other comprehensive income” in the consolidated statements of changes in shareholders’ equity.

f) Investments in non-consolidated companies

The Company uses the equity method of accounting for all long-term investments for which it owns between 20% and 50% of the investee’s outstanding voting stock or has the ability to exercise significant influence over operating and financial policies of the investee without controlling it. The equity method requires periodic adjustments to the investment account to recognize the Company’s proportionate share in the investee’s results, reduced by receipt of investee’s dividends.

g) Property, plant and equipment

· Costs incurred in oil and gas producing activities

The costs incurred in connection with the exploration, development and production of oil and gas are recorded in accordance with the “successful efforts” method. This method requires that costs the Company incurs in connection with the drilling of developmental wells and facilities in proved reserve production areas and successful exploratory wells be capitalized. In addition, costs the Company incurs in connection with geological and geophysical activities are charged to the statements of income in the year incurred, and the costs relating to exploratory dry wells on unproved reserve properties are charged to the statements of income when determined as dry or uneconomical.

· Capitalized costs

The capitalized costs are depreciated based on the unit-of-production method using proved developed reserves. These reserves are estimated by the Company’s geologists and petroleum engineers in accordance with SEC standards and are reviewed annually or more frequently when there are indications of significant changes.

· Property acquisition costs

Costs of acquiring developed or undeveloped leaseholds including lease bonus, brokerage, and other fees are capitalized. The costs of undeveloped properties that become productive are transferred to a producing property account.

g) Property, plant and equipment (Continued)

· Exploratory costs

Exploratory wells that find oil and gas in an area requiring a major capital expenditure before production begins are evaluated annually to assure that commercial quantities of reserves have been found or that additional exploration work is underway or planned. Exploratory costs related to areas where commercial quantities have been found are capitalized, and exploratory costs where additional work is underway or planned continue to be capitalized pending final evaluation. Exploratory well costs not meeting either of these tests are charged to expense. All other exploratory costs (including geological and geophysical costs) are expensed as incurred. Exploratory dry holes are expensed.

· Development costs

Costs of development wells including wells, platforms, well equipment and attendant production facilities are capitalized.

· Production costs

Costs incurred with producing wells are recorded as inventories and are expensed when the products are sold.

· Abandonment costs

The Company makes its annual reviews and revision of its estimated costs associated with well abandonment and the demobilization of oil and gas production areas, considering new information about date of expected abandonment and revised cost estimates to abandon. The changes in estimated asset retirement obligation are principally related to the commercial declaration of new fields, certain changes in cost estimates, and revisions to abandonment information provided for non-operated joint ventures, considering the useful economic life of the fields and the expected cash flows, to present value, at a rate of interest free of risks, adjusted by the Petrobras risk.

· Depreciation, depletion and amortization

Depreciation, depletion and amortization of leasehold costs of producing properties are recorded using the unit-of-production method applied on a field by field basis as a ratio of proved developed reserves. Production platform under capital lease which is not tied to the respective wells, are depreciated on a straight-line basis over the estimated useful lives of the platforms. Depreciation, depletion and amortization of all other capitalized costs (both tangible and intangible) of proved oil and gas producing properties is recorded using the unit-of-production method applied on a field by field basis as a ratio of proved developed reserves produced. The straight-line method is used for assets with a useful life shorter than the life of the field.

Other plant and equipment are depreciated on a straight line basis, based on the following estimated useful lives:

Class of assets	Useful life
	average weighted
Buildings and improvements	25 years (25-40 years)
Equipment and other assets	20 years (3-31 years)

· Impairment

In accordance with Codification Topic 360-10, management reviews long-lived assets, primarily property, plant and equipment to be used in the business and capitalized costs relating to oil and gas producing activities, whenever events or changes in circumstances indicate that the carrying value of an asset or group of assets may not be recoverable on the bases of undiscounted future cash flows. The reviews are carried out at the lowest level of assets to which the Company is able to attribute identifiable future cash flows. The net book value of the underlying assets is adjusted to their fair value using a discounted future cash flows model, if the sum of the expected undiscounted future cash flows is less than the book value.

The main assumptions of cash flows are: prices based on last strategic plan presented, production curves associated to existent projects comprising the Company’s portfolio, operating market costs and investments needed for projects conclusion.

· Maintenance and repairs

Maintenance and repairs, that do not embody significant improvements, are expensed as incurred, as well as planned major maintenances. Expenditures which appreciably extend the life, increase the capacity, or improve the efficiency of existing property are capitalized.

· Capitalized interest

Interest is capitalized in accordance with Codification Topic 835-20 - Capitalization of Interest Cost. Interest is capitalized on specific projects when a construction process involves considerable time and involves major capital expenditures. Capitalized interest is allocated to property, plant and equipment and amortized over the estimated useful lives or unit-of-production method of the related assets. Interest is capitalized at the Company’s weighted average cost of borrowings.

h) Revenues, costs and expenses

Revenue from sales of crude oil and oil products, petrochemical products, natural gas and other related products is recognized when title passes to the customer, because at that time the amount can be reasonably measured, collectibility is reasonably assured, persuasive evidence of an arrangement exists, the seller’s price to the buyer is fixed or determinable and the significant risks and rewards of ownership have been transferred. Title is transferred to the customer when delivery occurs pursuant to the terms of the sales contracts. Revenues from the production of natural gas properties in which Petrobras has an interest with other producers are recognized based on the actual volumes sold during the period. Subsequent adjustments to revenues based on production sharing agreements or volumetric delivery differences are not significant. Costs and expenses are accounted for on an accrual basis. Purchases and sales of inventory with the same counterparty (buy/sell arrangements) are combined and recorded on a net basis and reported in “Cost of Sales” on the Consolidated Statements of Income.

2. Summary of Significant Accounting Policies (Continued)

i) Income taxes

The Company accounts for income taxes in accordance with Codification Topic 740 -Accounting for Income, which requires an asset and liability approach to recording current and deferred taxes. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to the differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

The Company records the tax benefit of all net operating losses as a deferred tax asset and recognizes a valuation allowance for any part of this benefit which management believes will not be recovered against future taxable income using a “more likely than not” criterion.

In accordance with Codification Topic 740-10, the Company recognizes the effect of an income tax position only if that position is more likely that not of being sustained upon examination, based on technical merits of the position. A recognized income tax position is measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgement occurs. The Company records interests and penalties related to unrecognized tax benefits in “Other expenses”.

j) Employees’ postretirement benefits

The Company sponsors a contributory defined-benefit pension plan covering substantially all of its employees, which is accounted and disclosured for by the Company in accordance with Codification Topic 715 – Compensation-Retirement Benefits.

In addition, the Company provides certain health care benefits for retired employees and their dependents. The cost of such benefits is recognized in accordance with Codification Topic 715 – Compensation-Retirement Benefits.

The Company also contributes to the Brazilian pension and government sponsored pensions of international subsidiaries, social security and redundancy plans at rates based on payroll, and such contributions are expensed as incurred. Further indemnities may be payable upon involuntary severance of employees but, based on current operating plans, management does not believe that any amounts payable under this plan will be significant.

k) Earnings per share

Earnings per share are computed using the two-class method, which is an earnings allocation formula that determines earnings per share for both preferred shares, which are participating securities and common shares as if all of the net income for each year had been distributed in accordance with a predetermined formula described in Note 16(f).

l) Accounting for derivatives and hedging activities

The Company applies Codification Topic 815 – Derivatives and Hedging, together with its amendments and interpretations, referred to collectively herein as “ASC 815”. These rules require that all derivative instruments be recorded in the balance sheet of the Company as either an asset or a liability and measured at fair value. ASC 815 requires that changes in the derivative’s fair value be recognized in the income statement unless specific hedge accounting criteria are met; and the Company designates. For derivatives designated as accounting hedges, fair value adjustments are recorded either in the income statements or “Accumulated other comprehensive income”, a component of shareholders’ equity, depending upon the type of accounting hedge and the degree of hedge effectiveness.

The Company uses derivative financial instruments, not designated as hedge accounting, to mitigate the risk of unfavorable price movements for crude oil purchases. These instruments are marked-to-market with the associated gains or losses recognized as “Financial income” or “Financial expenses”.

The Company may also use non-hedging derivatives to mitigate the risk of unfavorable exchange-rate movements on its foreign currency-denominated funding. Gains and losses from changes in the fair value of these contracts are recognized as “Financial income” or “Financial expenses”.

The Company may also use hedging derivatives to protect exchange of interest rates in different currencies. These hedging derivatives used as well as the risk being hedged are accounted for a cash flow model. Under this model, the gains and losses associated with the derivative instruments are deferred and recorded in “Accumulated other comprehensive income” until such time as the hedged transaction impacts earnings, with the exception of any hedge ineffectiveness, which is recorded directly in the statements of income.

o) Change in accounting estimates

The Company changed at the beginning of 2010, as a consequence of the periodic assessment of the expected useful lives of its assets, depreciation rates from thermoelectric power plants and facilities from Refining, Transportation and Marketing segment, based on reports prepared by independent appraisers. The changes were accounted for prospectively in accordance with ASC 250 (Accounting changes and error corrections) and the Company’s results of operations were increased in US$352, net of taxes, in the year ended December 31, 2010.

The table below provides the previous and the current depreciation rates as a result of the assessment:

Estimated useful life	Previous	New (average)
Optic system equipment	7 years	20 years
Equipment and facilities of distribution	10 years	14 years
Industrial refining equipment and assemblies	10 years	20 years
Equipment and industrial plant fertilizer	10 years	22 years
Product storage tanks	10 years	26 years
Pipelines	10 years	31 years
Plataforms	16 years	27 years
Thermoelectric power plants	20 years	23 years

p) IFRS adoption for local purposes

The Brazilian Corporation Law was amended in 2007 to permit Brazilian GAAP to converge with International Financial Reporting Standards, or “IFRS”, as issued by the International Accounting Standards Board, or “IASB”. The adoption of IFRS in Brazil is mandatory for the year ended December 31, 2010 and as per current tax legislation, the resulting adjustments in relation to the previous practice are not included in the determination of current income tax charge.

The Company chose to present its financial statements for local purposes for the first time in accordance with IFRS in the first quarter of 2010. The Company’s financial statements prepared in accordance with U.S. GAAP were not affected by the adoption of IFRS other than dividends and profit sharing payable to our employees, which are based on the net income calculated under IFRS.

3. Income Taxes (Continued)

The Company has domestic accumulated tax loss carryforwards amounting to US$1,313 as of December 31, 2010, which are available to offset future taxable income, limited to 30% of taxable income in any individual year. These tax loss carryforwards can be carried forward indefinitely in Brazil. Management believes that for the tax benefits where valuation allowance is more likely than not that it will realize those tax benefits within ten years at the maximum.

The Company has foreign accumulated tax loss carryforwards amounting to US$5,684 as of December 31, 2010. Tax loss carryfowards exists in many international jurisdictions. Whereas some of these tax loss carryfowards do not have expiration date, others expire at various times from 2011 to 2030.

Valuation allowance has been established for certain credit loss carryfowards that reduce deferred tax to an amount that will, more likely than not, be realized. Annually management evaluates the realization of its deferred tax assets taking into consideration, among other elements, the level of historical taxable income, the projected future taxable income, tax-planning strategies, expiration dates of the tax loss carryforwards, and scheduled reversal of the existing temporary differences. The amount of the deferred tax asset considered realizable could, however, be reduced if estimates of future taxable income are reduced. The following presents the net change in the valuation allowance for the years ended December 31, 2010, 2009 and 2008:

	Year ended December 31,
	2010	2009	2008
Balance at January 1,	(1,699)	(1,614)	(667)
Additions	(146)	(185)	(1,071)

Cumulative translation adjustments	(3)	12	57
Balance at December 31,	(1,808)	(1,699)	(1,614)
Current valuation allowance	(5)	(8)	(5)
Long term valuation allowance	(1,803)	(1,691)	(1,609)

Valuation allowance additions of US$146 in 2010 and US$185 in 2009, primarily related to tax loss carryforwards from foreign operations and domestic thermoelectric power plants for which no tax benefit is expected to be realized in the foreseeable future.

The Company has not recognized a deferred tax liability of approximately US$449 for the undistributed earnings of its foreign operations that arose in 2010 and prior years as the Company considers these earnings to be indefinitely reinvested (US$280 in 2009). A deferred tax liability will be recognized when the Company no longer demonstrates that it plans to indefinitely reinvest the undistributed earnings. As of December 31, 2010, the undistributed earnings of these subsidiaries were approximately US$1,321 (US$823 as of December 31, 2009).

The Company has no unrecognized tax benefits relating to uncertain tax positions and accrued penalties and interest as of January 1, 2008, 2009 and 2010 and for the years ended December 31, 2008, 2009 and 2010. In addition, the Company does not expect that the amount of unrecognized tax benefits will increase significantly within the next 12 months.

The Company and its subsidiaries file tax returns in Brazilian jurisdiction and in many foreign jurisdictions for which is open for inspection depending on legislation applicable individually to them. In the case of the Brazilian and Argentinean tax positions, income tax returns remain subject to examination by the respective tax authorities for the years beginning in 2004.

Allowance on long-term receivables	(580)	(571)	(553)

At December 31, 2010 and 2009, long-term receivables include US$642 and US$633, respectively relating to payments made by the Company to suppliers and subcontractors on behalf of certain contractors. These contractors had been hired by the subsidiary Brasoil for the construction/conversion of vessels into FPSO (“Floating Production, Storage and Offloading”) and FSO (“Floating, Storage and Offloading”) and failed to make the payments to their suppliers and subcontractors. The Company made the payments to avoid further delays in the construction/conversion of the vessels and consequent losses to Brasoil.

The Company’s management has determined that these payments can be reimbursed, since they represent Brasoil’s rights with respect to the contractors, for which reason judicial action was filed with international courts to seek reimbursement. However, as a result of the uncertainties related to the realization of such receivables, the Company recorded an allowance for all credits not backed by collateral. Such allowance amounted to US$570 and US$561 as of December 31, 2010 and 2009, respectively.

9. Property, Plant and Equipment, Net (Continued)

a) Accounting treatment of Assignment Agreement (“Cessão Onerosa”)

On September 3, 2010, Petrobras entered into an agreement with the Brazilian federal government (Assignment Agreement), under which the government assigned to the Company the right to conduct research activities and the exploration and production of fluid hydrocarbons in specified pre-salt areas, subject to a maximum production of five billion barrels of oil equivalent up to 40 years renewable for more five years upon certain conditions.

The Assignment Agreement was approved by the Company’s Board of Directors and by the minority shareholders, following a valuation procedure based on, among other factors, an assessment prepared by independent third party experts.

The total purchase price of the rights acquired under the Assignment Agreement was US$43,868, paid to the Federal Government through funds obtained by the global offering of shares of the Company (see Note 16(a)), US$39,768 through the transfer of Brazilian Treasury Securities and the remaining US$4,100 in cash.

In accordance with ASC 932 “Extractive Activities - Oil and Gas”, the rights acquired by the Company were recognized as Property Plant & Equipment (long-term asset) as acquisition costs. The acquisition cost will be depreciated based on the unit-of-production method during the period of production of the related reserves and will also be subject to the impairment test. After the production of all the volumes that we were entitled, the acquisition costs will be completely depreciated.

The Assignment Agreement provides for a subsequent revision of the volume and the price, based on an independent third party assessment. If the contract parties determine that the value of the rights acquired is higher than the initial purchase price, the Company may either pay the difference to the Brazilian federal government, in which case is expected the recognition of the difference as Property Plant & Equipment (long-term asset), or reduce the total volume acquired under the contract, in which case there would be no impact on the balance sheet. If the contract parties determine that the value of the rights acquired is lower than the initial purchase price, the Brazilian federal government will pay for the difference in cash and/or bonds, dependent of Government Budget conditions and it is expected a reduction of the amount originally recorded as Property Plant & Equipment (long-term asset) by the amount received from the Brazilian federal government.

The knowledge of the reserves and the geological uncertainties remain unchanged since the signing of the assignment agreement. The final value of the cost of the assignment will depend mainly on full knowledge: of the reserves, of the production scenarios and the technologies to be developed, which should occur not later than 2014, the deadline stipulated for the declaration of commercialization.

The Company will record any adjustment to the acquisition cost, when it is probable and determinable it will pay or receive in the future, amounts as a result of the subsequent revision.

b) Codification Topic 410 - Asset Retirement Obligations

In accordance with Codification Topic 410-20, adopted by Petrobras since January 2003, the fair value of asset retirement obligations are recorded as liabilities on a discounted basis when they are incurred, which is typically at the time the related assets are installed. Amounts recorded for the related assets will be increased by the amount of these obligations and depreciated over the related useful lives of such assets. Over time, the amounts recognized as liabilities will be accreted for the change in their present value until the related assets are retired or sold.

Measurement of asset retirement obligations is based on currently enacted laws and regulations, existing technology and site-specific costs. There are no assets legally restricted to be used in the settlement of asset retirement obligations.

A summary of the annual changes in the asset retirement obligations is presented as follows:

	Liabilities
Balance as of December 31, 2008	2,825
Accretion expenses	164
Liabilities incurred	24
Liabilities settled	(4)

c) Impairment

For the years ended December 31, 2010, 2009 and 2008, the Company recorded impairment charges of US$402, US$319 and US$519, respectively. During 2010, the impairment charge was primarily related to producing properties in Brazil (US$346) and due to the impairment of assets held for sale, referring to the refining and distribution segments in Argentina (US$56). The petroleum and natural gas fields that presented losses already had high maturity levels and, consequently, produced insufficient petroleum and gas to cover production costs. This factor had a reducing effect on the economic analysis that led to the recording of a provision for loss through devaluation in some fields.

10. Investments in Non-Consolidated Companies and Other Investments

Petrobras conducts portions of its business through investments in companies accounted for using the equity and cost methods. These non-consolidated companies are primarily engaged in the petrochemicals and product transportation businesses.

		Investments
	Total ownership	2010	2009
Equity method	20 % - 50% (1)	5,957	3,988
Investments at cost		355	362
Total		6,312	4,350

(1) As described further in this Note, certain thermoelectrics with ownership of 10% to 50% are also accounted as equity investments due to particularities of significant influence.

At December 31, 2010, the Company had investments interest of 36.1% with balance of US$2,867 in Braskem S.A., that were recorded according to equity method.

The Company also has investments in companies for the purpose of developing, constructing, operating, maintaining and exploring thermoelectric plants included in the federal government’s Priority Thermoelectric Energy Program, with equity interests of between 10% and 50%. The balance of these investments as of December 31, 2010 and 2009 includes US$118 and US$110 respectively, and are included as equity method investments due to the Company’s ability to exercise significant influence over such operations.

e) Guarantees and covenants

Financial institutions abroad do not require guarantees from the Company. The financing granted by BNDES - National Bank for Social and Economic Development is guaranteed by a lien on the assets being financed (carbon steel pipes for the Bolivia-Brazil gas pipeline and vessels).

On account of a guarantee agreement issued by the Federal Goverment in favor of Multilateral Loan Agencies, motivated by financings funded by TBG, counter guarantee agreements were signed, which had as signatories the Federal Government, TBG, Petrobras, Petroquisa and Banco do Brasil S.A., where TBG undertakes to entail its revenues to the order of the Brazilian Treasuary until the settlement of the obligations guaranteed by the Federal Government. This debt had an outstanding balance of US$213 and US$253 at December 31, 2010 and 2009, respectively.

In guarantee of the debentures issued, REFAP has a short-term investment account (bank deposits indexed to credit operations), tied to variations of the Interbank Deposit Certificate -CDI. REFAP has to maintain three times the value of the sum of the last installment due of the amortization of the principal and related charges.

At December 31, 2010 and 2009, Gaspetro had secured certain debentures issued to finance the purchase of the transportation rights in the Bolivia/Brazil pipeline with 3,000 shares of its interest in TBG, a subsidiary of Gaspetro responsible for the operation of the pipeline.

The Company’s debt agreements contain affirmative covenants regarding, among other things provision of information; financial reporting; conduct of business; maintenance of corporate existence; maintenance of government approvals; compliance with applicable laws; maintenance of books and records; maintenance of insurance; payment of taxes and claims; and notice of certain events. The Company’s debt agreements also contain negative covenants, including: without limitation; limitations on the incurrence of indebtedness; limitations on the incurrence of liens; limitations on transactions with affiliates; limitations on the disposition of assets; limitation on consolidations, mergers, sales and/or conveyances; negative pledge restrictions; change in ownership limitations; ranking; use of proceeds limitations; and required receivables coverages. Petrobras’ management affirms that the Company is in compliance with the covenants within debt agreements.

15.1) Pension plans in Brazil – Defined benefit and variable contribution

a) Petros Plan - Fundação Petrobras de Seguridade Social

The Fundação Petrobras de Seguridade Social (Petros) was established by Petrobras as a private, legally separate nonprofit pension entity with administrative and financial autonomy.

The Petros plan is a contributory defined-benefit pension plan introduced by Petrobras in July of 1970, to supplement the social security pension benefits of employees of Petrobras and its Brazilian subsidiaries and affiliated companies. The Petros Plan is now closed to new employees of the Petrobras system since September 2002.

15.1) Pension plans in Brazil – Defined benefit and variable contribution (Continued)

a) Petros Plan - Fundação Petrobras de Seguridade Social (Continued)

Additionally, Petros is funded by income resulting from the investment of these contributions. The Company’s funding policy is to contribute to the plan annually the amount determined by actuarial calculations. In the calendar 2010 year, benefits paid totaled US$1,054 (US$911 in 2009).

The Company’s liability related to future benefits to plan participants is calculated on an annual basis by an independent actuary, based on the Projected Unit Credit method. The assets that guarantee the pension plan are presented as a reduction to the net actuarial liabilities.

The actuarial gains and losses generated by the differences between the values of the obligation and assets determined based on projections and the actual figures are respectively included or excluded from the calculation of the net actuarial liability and recorded as “Postretirement benefit reserves adjustments net of tax - pension cost”, in shareholders’ equity. Actuarial gains and losses are amortized during the average remaining service period of the active employees of approximately 6.5 years at December 31, 2009, in accordance with the procedure established by Codification Topic 715.

The relation between contributions by the sponsors and participants of the Petros Plan, considering only those attributable to the Company and subsidiaries in the 2010 and 2009 financial years was 1.00 to 1.00. The Company’s best estimate of contributions expected to be paid in 2011 respective to the pension plan approximates US$540, with total pension benefit payments in 2011 expected to be US$1,695.

According to Constitutional Amendment No. 20 of 1998, the computation of any deficit in the defined-benefit plan in accordance with the actuarial method of the current plan (which differs from the method defined in Codification Topic 715), must be equally shared between the sponsor and the participants, by an adjustment to the normal contributions.

Petrobras and its subsidiaries sponsoring the Petros plan, trade unions and Petros executed a Financial Commitment Agreement on October 23, 2008, after legal homologation on August 25, 2008, to cover commitments with pension plans, which will be paid in semi-annually installments with interest of 6% p.a. on the debtor balance updated by the IPCA, for the next 20 years, as previously agreed during the renegotiation. At December 31, 2010, the balance of the obligation of Petrobras and subsidiaries referring to the Financial Commitment Agreement was US$2,874, of which US$175 matures in 2011, which are recognized in these consolidated financial statements.

15.1) Pension plans in Brazil – Defined benefit and variable contribution (Continued)

a) Petros Plan - Fundação Petrobras de Seguridade Social (Continued)

The Company’s obligation, through the Financial Commitment Agreement, presents a counterpart to the concessions made by the members/beneficiaries of the Petros Plan in the amendment of the plan’s regulations, in relation to the benefits, and in the closing of existing litigations.

At December 31, 2010, Petrobras had long-term National Treasury Notes in the amount of US$2,939 (US2,363 at December 31, 2009), acquired to balance liabilities with Petros, which will be held in the Company’s portfolio and used as a guarantee for the Financial Commitment Agreement.

Petrobras has aggregated information for all defined benefit pension plans. The domestic benefit plans of Petrobras, BR Distribuidora, Petroquisa, and REFAP contain similar assumptions and the benefit obligation related to Petrobras Argentina, the international plan, is not significant to the total obligation and thus has also been aggregated. All Petrobras group pension plans have accumulated benefit obligation in excess of plan assets.

The determination of the expense and liability relating to the Company’s pension plan involves the use of judgment in the determination of actuarial assumptions. These include estimates of future mortality, withdrawal, changes in compensation and discount rate to reflect the time value of money as well as the rate of return on plan assets. These assumptions are reviewed at least annually and may differ materially from actual results due to changing market and economic conditions, regulatory events, judicial rulings, higher or lower withdrawal rates or longer or shorter life spans of participants.

According to the requirements of Codification Topic 715, and subsequent interpretations, the discount rate should be based on current prices for settling the pension obligation. Applying the precepts of Codification Topic 715, in historically inflationary environments such as Brazil creates certain issues as the ability for a company to settle a pension obligation at a future point in time may not exist as long-term financial instruments of suitable grade may not exist locally as they do in the United States.

Although the Brazilian market has been demonstrating signs of stabilization under the present economic model, as reflected in market interest rates, it is not yet prudent to conclude that market interest rates will be stable.

15.1) Pension plans in Brazil – Defined benefit and variable contribution (Continued)

b) Petros Plan 2 - Fundação Petrobras de Seguridade Social

As from July 01, 2007, the Company implemented the new supplementary pension plan, a Variable Contribution (CV) or mixed plan, called Petros Plan 2, for employees with no supplementary pension plan.

Petrobras and the other sponsors fully assumed the contributions corresponding to the period in which the participants had no plan. This past service shall consider the period as from August 2002, or from the date of hiring, until August 29, 2007. The plan will continue to admit new subscribers after this date but no longer including any payment for the period relating to past service.

A portion of this plan with defined benefits characteristics refers to the risk coverage for disability and death, a guarantee of a minimum benefit and a lifetime income, and the related actuarial commitments are recorded according to the projected credit unit method. The portion of the plan with defined contribution characteristics, earmarked for forming a reserve for programmed retirement, was recognized in the results for the year as the contributions are made. In fiscal year 2010, the contribution of Petrobras and subsidiaries to the defined contribution portion of this plan was US$231.

The disbursements related to the cost of past service will be made on a monthly basis over the same number of months during which the participant had no plan and, therefore, should cover the part related to the participants and the sponsors.

The actuarial evaluation in 2009 of Fundação Petros, to attend the rules for Supplementary Pensions, showed evidence of a lower level of loss from risk events in the year, and it also observed that the balance of the collective risk fund presented an amount sufficient to cover the estimated benefits for 2010. Accordingly, the Foundation followed the actuary’s suggestion that the risk contributions were redirected to the member’s account in the plan during the first semester of 2010.

15.2) Pension plans abroad - Defined benefit

The main defined benefit plans offered by the subsidiaries of Petrobras Internacional Braspetro B.V. (PIB BV), are as follows:

• Petrobras Energía S.A.

a) “Termination Indemnity” Plan

This is a benefit plan in which employees who meet certain targets are eligible on retirement to receive one month’s salary for each year they have worked in the company, according to a decreasing scale, according to the number of the years the plan has existed.

b) “Compensating Fund”

This benefit is available to all Pesa employees who have joined the defined contribution plans in force in the past and who joined the company prior to May 31, 1995 and have accumulated the required time of service.

• Nansei Sekiyu S.A.

The Nansei Sekiyu Refinery offers its employees a programmed supplementary retirement benefits plan, a defined benefit plan, where the members in order to become eligible for the benefit need to be at least 50 years old and have 20 years service in the company. Contributions are made only by the sponsor.

15.3) Other defined contribution plans

The subsidiaries Transpetro and some subsidiaries of Petrobras sponsor defined contribution retirement plans for their employees

15.4) Plan assets

Investment Policies and Strategies

The Corporation’s investment strategy for benefit plan assets reflects a long-term view, a careful assessment of the risks inherent in various asset classes and diversification to reduce the risk of the portfolio. The plan asset portfolio should follow the policies established by the Central Bank of Brazil. The fixed income funds are largely invested in corporate and government debt securities. The target asset allocation for the period between 2011-2015 is (25%-70%) fixed income, (15%-50%) variable income, (1,5%- 8%) real estate, (0%-15%) loans to participants of the plan and (2,5% - 15%) other investments.

15.5) Health care benefits - “Assistência Multidisciplinar de Saúde” (AMS)

Petrobras and its Brazilian subsidiaries maintain a health care benefit plan (AMS), which offers defined benefits and covers all employees (active and inactive) together with their dependents. The plan is managed by the Company, with the employees contributing fixed amounts to cover principal risks and a portion of the costs relating to other types of coverage in accordance with participation tables defined by certain parameters including salary levels, besides the Medicine Benefit, which provides special terms on the acquisition of certain medicines from participating drugstores, located throughout Brazil.

The Company’s commitment related to future benefits to plan participants is calculated on an annual basis by an independent actuary, based on the Projected Unit Credit method. The health care plan is not funded or otherwise collateralized by assets. Instead, the Company makes benefit payments based on costs incurred by plan participants.

a) Capital

The Company’s subscribed and fully paid-in capital at December 31, 2010 consisted of 7,442,454,142 common shares and 5,602,042,788 preferred shares (5,073,347,344 common shares and 3,700,729,396 preferred shares at December 31, 2009). The preferred shares do not have any voting rights and are not convertible into common shares and vice-versa. Preferred shares have priority in the receipt of dividends and return of capital.

The Extraordinary General Meeting held on March 24, 2008, decided to effect a split of each Company’s share into two, resulting: (a) in a free distribution of 1 (one) new share of the same type for each original share and based on the shareholding structure at April 25, 2008; (b) in a free distribution of 1 (one) new American Depository Shares (ADS) of the same type for each original ADS and based on the shareholding structure at April 25, 2008. At the same date, an amendment to article 4 of the Company’s bylaws to cause capital be divided into 8,774,076,740 shares, of which 5,073,347,344 are common shares and 3,700,729,396 are preferred shares, with no nominal value, was approved. This amendment to the Company’s bylaws is effective from April 25, 2008. The relation between the ADS and shares of each class remains of 2 (two) shares for one ADS. All share, ADS, per share and per ADS information in the accompanying financial statements and notes have been adjusted to reflect the result of the share split.

Current Brazilian law requires that the Federal Government retains ownership of 50% plus one share of the Company’s voting shares.

b.1) Expenditures with the issuing of shares

The Global Offering direct costs in the amount of US$279, net of taxes, were recorded in shareholders’ equity.

c) Appropriated retained earnings

Brazilian Law and the Company’s bylaws require that certain appropriations be made from retained earnings to reserve accounts annually. The purpose and basis of appropriation to such reserves are as follows:

• Legal reserve

This reserve is a requirement for all Brazilian corporations and represents the annual appropriation of 5% of net income as stated in the statutory accounting records up to a limit of 20% of capital stock. The reserve may be used to increase capital or to compensate for losses, but may not be distributed as cash dividends.

• Statutory reserve

This reserve is provided through an amount equivalent to a minimum of 0.5% of subscribed and fully paid in capital at year-end. The reserve is used to fund the costs incurred with research and technological development programs. The accumulated balance of this reserve cannot exceed 5% of the capital stock, according to Article 55 of the Company’s bylaws.

• Tax incentive reserve

This reserve consists of investments in tax incentives, arising from allocations of part of the Company’s income tax. It relates to tax incentives in the Northeast, within the region covered by the Northeast Development Agency (ADENE), granting a 75% reduction in income tax payable, calculated on the profits of the exploration of the incentived activities. Up to December 31, 2010, this incentive amounted to US$131 (US$167 on December 31, 2009), which may only be utilized to offset losses or for a capital increase, as provided for in Article 545 of the Income Tax Regulations and has been accounted for under the flow through method.

On May 10, 2007, the Brazilian Federal Revenue Office recognized Petrobras’ right to deduct this incentive from income tax payable, covering the tax years of 2006 until 2015.

This interest on shareholders’ equity should be discounted from the remuneration that will be distributed at the closing of the fiscal year 2010. The amount will be monetarily updated according to the variation of the SELIC rate since the date of effective payment until the end of the aforementioned fiscal year.

17. Acquisition/Sales of Assets and Interests

a) Goodwill

Goodwill represents the excess of the purchase price over the estimated fair value of the net assets acquired in the acquisition of a business. In accordance with Codification Topic 350 -Goodwill and Other Intangible Assets (“ASC 350”), the Corporation’s goodwill is not amortized, but is tested for impairment at a reporting unit level, which is an operating segment or one level below an operating segment. The Company conducts its annual goodwill impairment review in the fourth quarter of each year and whenever events and changes in circumstances suggest that the carrying amount may not be recoverable.

Goodwill impairment encompasses a two step approach. In the first step the Company compares the fair value of the reporting unit with its carrying amount, including goodwill. If the fair value is lower than the carrying amount including goodwill, there is an indication of impairment loss that is measured by performing the second step. In the second step, the estimated fair value from the first step is used as the purchase price in a hypothetical acquisition of the reporting unit. Purchase business combination accounting rules are followed to determine a hypothetical purchase price allocation to the reporting unit’s assets and liabilities. The residual amount of goodwill that results from this hypothetical purchase price allocation is compared to the recorded amount of goodwill for the reporting unit, and the recorded amount is written down to the hypothetical amount, if lower.

Change in the balance of goodwill for the years ended December 31, 2010 and 2009:

Balance as of December 31, 2008	118
Cumulative translation adjustment	21
Balance as of December 31, 2009	139
Acquisitions in Chile	49
Cumulative translation adjustment	4
Balance as of December 31, 2010	192

• Operations in Ecuador

In 2006, the Ecuadorian government began a series of tax and regulatory reforms with respect to hydrocarbon activities, which significantly affected the agreements for participation in exploration blocks. As from November 24, 2010, all the exploration agreements in force until then had to migrate to service agreements.

Petrobras Argentina S.A. (PESA), through Sociedade Ecuador TLC S.A., holds a 30% interest in the exploration agreements for Block 18 and the unified Palo Azul field, located in the Oriente basin of Ecuador.

PESA decided not to accept the final proposal to migrate its agreements to the new contractual model, thus it is the responsibility of the Ecuadorian Government to indemnify the investments made in those exploration blocks.

Also in Ecuador, PESA has a Ship or Pay agreement entered into with Oleoducto de Crudos Pesados Ltd (OCP) for transporting oil, which is in force since November 10, 2003 with an effective term of 15 years. On account of the commitments assumed for the transport capacity contracted and not used due to the decrease in the volume of oil traded, it recorded liabilities of US$85 at December 31, 2010.

18. Commitments and Contingencies

a) Commitments

• Commitments for purchase of natural gas

Petrobras entered into an agreement with Yacimientos Petrolíferos Fiscales Bolivianos (YPFB), to purchase a total of 201.9 billion m³ of natural gas during the term of the agreement, undertaking to purchase minimum annual volumes at a price calculated according to a formula indexed to the price of fuel oil. The agreement is valid until 2019 and will be renewed until the total contracted volume has been consumed. The pipeline achieved an average throughput of 22.0 million cubic meters per day during 2010.

In the period between 2002 and 2005, Petrobras bought less than the minimum volume established in the agreement with YPFB and paid US$81, referring to the volumes not transported, the credits for which will be realized through the drawing of future volumes.

The commitments for purchases of gas up to the end of the agreement represent annual average volumes of 24 million cubic meters per day.

In the fourth quarter of 2009 Petrobras and YPFB signed a contractual addendum which regulates the payment of additional amounts to YPFB referring to the quantity of liquids (heavy hydrocarbons) present in the natural gas imported by Petrobras from YPFB through a Gas Supply Agreement (GSA). The addendum establishes additional amounts between US$100 and US$180 per year, applied to the volumes of gas delivered as from May 2007. With respect to 2007, the obligation for additional payment by Petrobras was recorded as a provision and was settled in February 2010. The payment of the amounts referring to subsequent years will only be due after compliance with a condition precedent established in the addendum, which will demand additional negotiations with YPFB.

• Commitments for purchase of oil and oil products

In an effort to ensure procurement of oil products for the Company’s customers, the Company currently has several short and long-term normal purchase contracts with maturity dates up to 2019, which collectively obligate it to purchase a minimum of approximately 453,802 barrels of crude oil and oil products per day at market prices.

Petrobras provided guarantees to the ANP for the minimum exploration program defined in the concession contracts for exploration areas, totaling US$3,209 (US$2,355 in 2009). Out of this total, US$2,849 (US$2,042 in 2009) represents a pledge on the oil to be extracted from previously identified fields already in production, for areas in which the Company had already made commercial discoveries or investments. For areas whose concessions were obtained by bidding from the ANP, Petrobras has given bank guarantees totaling US$1,096 through December 31, 2010 (US$333 in 2009).

b) Litigation

Petrobras is subject to a number of commitments and contingencies arising in the normal course of its business. Additionally, the operations and earnings of the Company have been, and may be in the future, affected from time to time in varying degrees by political developments and laws and regulations, such as the Federal Government’s continuing role as the controlling shareholder of the Company, the status of the Brazilian economy, forced divestiture of assets, tax increases and retroactive tax claims, and environmental regulations. The likelihood of such occurrences and their overall effect upon the Company are not predictable.

b) Litigation (Continued)

b.1) Proceedings classified as probable losses

The principal proceedings, disclosed previously as a possible loss, this quarter are classified as a probable loss, due to the development of the legal case or agreements in progress, as follows:

• ICMS - Sinking of Platform P-36

In 2001, Platform P-36 was imported by Petrobras through temporary admission in accordance with the special regime for imports and exports (REPETRO) which suspends taxation and, therefore, on this occasion state taxes were not due.

With the sinking of the platform, in March 2001, the State of Rio de Janeiro initiated actions for collection of the suspended ICMS through tax foreclosure proceedings as it understands that there will no longer be return of the platform.

In February 2010, with an unfavorable decision at the last level of appeals in the Superior Court of Rio de Janeiro, Petrobras began to evaluate the legal aspects of the suit and the economic aspects of the use of the benefits of tax amnesty established in State Law 5,647, of January 18, 2010, which permits elimination of fines and an expressive decrease in other charges, as well as the possibility of payment with court order debts.

Petrobras adhered to the payment conditions of the aforementioned State Law, fixing the total amount agreed upon with the State of Rio de Janeiro in the amount of US$269, where US$65 was in court order debts.

• Triunfo Agro Industrial S.A and others

During the year 2000, Triunfo Agro Industrial and Others filed a suit against Petrobras, claiming losses and damages as a result of the annulling of a credit assignment transaction – excise tax (IPI) premium. The hearing by the Superior Court of Rio de Janeiro, in the second instance, was unfavorable to Petrobras and approval was denied for the appeal lodged by the Company.

Parallely to the filing of the aforementioned appeals, on September 28, 2010 Petrobras filed a motion for annulling judgment before the Full Bench of the Superior Court of Rio de Janeiro, where it obtained, by 20 votes to one, an injunction that prohibits any withdrawal of values on the part of the plaintiffs.

• Triunfo Agro Industrial S.A and others (Continued)

Based on its legal counsels’ advice, the Company has assessed risk of loss to be probable. The maximum estimated exposure as at December 31, 2010, is around US$298, which has been provided. The Company has a balance of deposits in court for this process in the amount of US$205, resulting in a net amount of US$94.

• Notice of infraction – National Agency for Petroleum, Natural Gas and Biofuel – ANP

On July 1, 2010, the Company received a notice that a suit had been filed by ANP, in the amount of US$133, for the alleged miscalculations of the special participation tax basis in the Barracuda and Caratinga fields. On July 15, 2010, Petrobras filed its defense with ANP.

On September 30, ANP presented a new official letter, with a review of the amount for the official notification, as it understands that part of the leasing agreement would not consist of a financing transaction.

On October 28, 2010, Petrobras filed with ANP a request for payment in installments over 30 months in a total amount of US$52, based on the amount established in Official letter 646/2010/SPG, of October 15, 2010. Until December 31, 2010, the Company had paid three installments.

Plaintiff: The Fisherman’s Federation of the State of Rio de Janeiro (FEPERJ)

On behalf of its members, FEPERJ is making a number of claims for indemnification as a result of an oil spill in Guanabara Bay which occurred on January 18, 2000. At the time, Petrobras paid out extrajudicial indemnification to all who proved they were fishermen when the accident happened. According to the records of the national fishermen’s registry, only 3,339 people were eligible to claim indemnification.

Plaintiff: The Fisherman’s Federation of the State of Rio de Janeiro (FEPERJ) (Continued)

On February 2, 2007, the decision, partially accepting the expert report, was published and, on the pretext of quantifying the amount of the conviction, established that the parameters for the respective calculation based on the criteria would result in an amount of US$661. Petrobras appealed against this decision before the Court of Appeals of Rio de Janeiro, as the parameters stipulated in that the decision had already been specified by the Court of Appeals of Rio de Janeiro, itself. The appeal was accepted. On June 29, 2007, the decision of the First Civil Chamber of the Court of Appeals of the State of Rio de Janeiro was published, denying approval of the appeal filed by Petrobras and approving the appeal lodged by FEPERJ. Special appeals were lodged by Petrobras against this decision, which in a decision handed down on November 19, 2009 by the Superior Court of Justice, were considered fit annul the court decision of the First Civil Chamber of the Superior Court of Rio de Janeiro. Publication of the court decision is being awaited in order to evaluate whether new appeals will be lodged by FEPERJ, or whether the process will be returned to the Superior Court of Rio de Janeiro for a new hearing.

In accordance with the Company’s expert assistant calculation, the recorded amount ofUS$30 represents the award that will be set by the court at the end of the process. Based on its legal counsels’ advice, the Company has assessed risk of loss to be probable.

Plaintiff: Federal Revenue Department of Rio de Janeiro - Income Tax Withheld at Source related to CLEP

On July 16, 2009, Companhia Locadora de Equipamentos Petrolíferos (CLEP) received an assessment notice questioning the rate of Income Tax Withheld at Source, applicable to the issuing of securities abroad. Possibility of applying the Brazil - Japan Treaty (Dec. 61.889/67). On August 14, 2009, CLEP filed a refutation of this tax assessment notice in the Regional Federal Revenue Office of Rio de Janeiro. On September 3, 2009 the process was remitted to the Control and Hearing Service - DRJ. The maximum updated exposure for Petrobras as at December 31, 2010 is US$250. These amounts refer to the consolidated companies and were offset against the balance of financing in current and non-current liabilities.

The petition for an injunction for renewal of the notification of the decision handed down in the Administrative Process and suspension of the demandability of the debit of income tax withheld at source was dismissed, which permitted the filing of a bill of review on November 19, 2010.

b.2) Proceedings classified as possible losses

Plaintiff: Porto Seguro Imóveis Ltda.

On November 23, 1992, Porto Seguro Imóveis Ltda., a minority shareholder of Petroquisa, filed a suit against Petrobras in the State Court of Rio de Janeiro related to alleged losses resulting from the sale of a minority holding by Petroquisa in various petrochemical companies included in the National Privatization Program introduced by Law No. 8,031/90.

In this suit, the plaintiff claims that Petrobras, as the majority shareholder in Petroquisa, should be obliged to reinstate the “loss” caused to the net worth of Petroquisa, as a result of the acts that approved the minimum sale price of its holding in the capital of privatized companies. A decision was handed down on January 14, 1997, that considered Petrobras liable with respect to Petroquisa for losses and damages in an amount equivalent to US$3,406.

In addition to this amount, Petrobras was required to pay the plaintiff 5% of the value of the compensation as a premium (see art. 246, paragraph 2 of Law No. 6,404/76), in addition to attorneys’ fees of approximately 20% of the same amount.

In performance of the decision published on June 05, 2006, the Company is now awaiting assignment of the agenda to re-examine the matter relating to the blocking of Petrobras’ Special Appeal.

Petrobras filed a special, extraordinary appeal before the Superior Court of Justice (STJ) and the Federal Supreme Court (STF), which were rejected. Petrobras then filed an interlocutory appeal against the decision before the Superior Court of Justice and the Federal Supreme Court.

The Special Appeal offered by Porto Seguro, which sought to bar the processing of the Special Appeal by Petrobras was heard and dismissed in December 2009.

If the award is not reversed, the indemnity estimated to Petroquisa, including monetary correction and interest, would be US$11,422. As Petrobras owns 100% of Petroquisa’s share capital, a portion of the indemnity estimated at US$7,539, will not represent a disbursement from Petrobras’ Group. In case of loss, Petrobras would have to pay US$571 to Porto Seguro and US$2,284 to Lobo & Ibeas by means of attorney’s fees. Based on its legal counsels’ advice, the Company has assessed risk of loss to be possible.

Plaintiff: Kalium Mineração S.A.

Plaintiff: Internal Revenue Service of Rio de Janeiro - Withholding Income Tax related to charter of vessels

The Internal Revenue Service of Rio de Janeiro filed two Tax Assessments against the Company in connection with Withholding Income Tax on foreign remittances of payments related to charter of vessels of movable platform types for the years 1999 through 2002.

The Internal Revenue Service, based on Law No. 9,537/97, Article 2, considers that drilling and production platforms cannot be classified as sea-going vessels and therefore should not be chartered but leased. Based on this interpretation, overseas remittances for servicing chartering agreements would be subject to withholding tax at the rate of 15% or 25%.

Petrobras has defended itself against these tax assessments. Administrative appeals were lodged with High Court of Appeals for Fiscal Matters, last administrative level, which still await trial. The maximum exposure including monetary restatement for Petrobras as of December 31, 2010 is US$2,717. Based on its legal counsels’ advice, the Company has assessed risk of loss to be possible.

19. Derivative Instruments, Hedging and Risk Management Activities

The Company is exposed to a number of market risks arising from its normal course of business. Such market risks principally involve the possibility that changes in interest rates, foreign currency exchange rates or commodity prices will adversely affect the value of the Company’s financial assets and liabilities or future cash flows and earnings.

The Company maintains a corporate risk management policy that is executed under the direction of the Company’s executive officers. In 2004, the Executive Committee of Petrobras set up the Risk Management Committee composed of executive managers from all the business departments and from a number of corporate departments. This committee, as well as having the objective of assuring integrated management of exposures to risks and formalizing the main guidelines for the Company’s operation, aims at concentrating information and discussing actions for risk management, facilitating communication with the executive offices and the Board of Directors in aspects related to best corporate governance practices.

The risk management policy of the Petrobras System aims at contributing towards an appropriate balance between its objectives for growth and return and its level of risk exposure, whether inherent to the exercise of its activities or arising from the context within which it operates, so that, through effective allocation of its physical, financial and human resources the Company may attain its strategic goals.

19. Derivative Instruments, Hedging and Risk Management Activities (Continued)

The Company may use derivative and non-derivative instruments to implement its corporate risk management strategy. However, by using derivative instruments, the Company exposes itself to credit and market risk. Credit risk is the failure of a counterparty to perform under the terms of the derivative contract. Market risk is the possible adverse effect on the value of an asset or liability, including financial instruments that results from changes in interest rates, currency exchange rates, or commodity prices. The Company addresses credit risk by restricting the counterparties to such derivative financial instruments to major financial institutions. Market risk is managed by the Company’s executive officers. The Company does not hold or issue financial instruments for trading purposes.

a) Commodity price risk management

The Company is exposed to commodity price risks as a result of the fluctuation of crude oil and oil product prices. The Company’s commodity risk management activities are primarily undertaking through the uses of future contracts traded on stock exchanges; and options and swaps entered into with major financial institutions. The Company does not use derivatives contracts for speculative purposes.

The Company does not usually use derivatives to manage overall commodity price risk exposure, taking into consideration that the Company’s business plan uses conservative price assumptions associated to the fact that, under normal market conditions, price fluctuations of commodities do not represent a substantial risk to achieving strategic objectives.

The decision to enter into hedging or non-hedging derivatives is reviewed periodically and recommended, or not, to the Risk Management Committee. If entering into derivative is indicated, in scenarios with a significant probability of adverse events, and such decision is approved by the Board of Directors, the derivative transactions should be carried out with the aim of protecting the Company’s solvency, liquidity and execution of the corporate investment plan, considering an integrated analysis of all the Company’s risk exposures.

Outstanding derivatives contracts were entered into in order to mitigate price risk exposures from specific transactions, in which positive or negative results in the derivative transactions are totally or partially offset by the opposite result in the physical positions. The transactions covered by commodity derivatives are: certain cargoes traded from import and export operations and transactions between different geographical markets.

As a result of the Company currently price risk management, the derivatives are contracted as short term operations, to mitigate the price risk of specific forecasted transactions. The operations are carried out on the New York Mercantile Exchange (NYMEX) and the Intercontinental Exchange (ICE), as well as on the international over-the-counter market.

19. Derivative Instruments, Hedging and Risk Management Activities (Continued)

a) Commodity price risk management (Continued)

The Company’s exposure from these contracts is limited to the difference between the contract value and market value on the volumes contracted. Crude oil future contracts are marked-to-market and related gains and losses are recognized in currently period earnings, irrespective of when the physical crude sales occur.

The main parameters used in risk management for variations of Petrobras’ oil and oil products prices are the cash flow at risk (CFAR) for medium-term assessments, Value at Risk (VAR) for short-term assessments, and Stop Loss. Corporate limits are defined for VAR and Stop Loss.

The hedges settled during the period from January to December 2010 corresponded to approximately 98% of the traded volume of imports and exports to and from Brazil plus the total volume of the products traded abroad.

The main counterparts of operations for derivatives for oil and oil products are the New York Stock Exchange (NYMEX), Intercontinental Exchange (ICE), BP North America Chicago, Morgan Stanley and Shell (Stasco).

The commodity derivatives contracts are reflected at fair value as either assets or liabilities on the Company’s consolidated balance sheets recognizing gain or losses in earnings, using market to market accounting, in the period of change.

As of December 31, 2010, the Company had the following outstanding commodity derivative contracts that were entered into:

	Notional amount in
Commodity Contracts	thousands of bbl*
Maturity 2010	As of December 31, 2010
Futures and Forwards contracts	(8,216)
Options contracts	(1,679)
* A negative notional value represents a sale position.

b) Foreign currency risk management

Exchange risk is one of the financial risks that the Company is exposed to and it originates from changes in the levels or volatility of the exchange rate. With respect to the management of these risks, the Company seeks to identify and handle them in an integrated manner, seeking to assure efficient allocation of the resources earmarked for the derivative.

Taking advantage of operating in an integrated manner in the energy segment, the Company seeks, primarily, to identify or create “natural risk mitigation”, benefiting from the correlation between its income and expenses. In the specific case of exchange variation inherent to the contracts with the cost and remuneration involved in different currencies, this natural risk mitigation is carried out through allocating the cash investments between the real and the US dollar or another currency.

The management of risks is done for the net exposure. Periodical analyses of the exchange risk are prepared, assisting the decisions of the executive committee. The exchange risk management strategy involves the use of derivative instruments to minimize the exchange exposure of certain Company’s obligations.

Petrobras Distribuidora (wholly owned subsidiary) entered into an over the counter contract, not designated as hedge accounting, for covering the trading margins inherent to exports (aviation segment) for foreign clients. The objective of the operation, contracted contemporaneously with the definition of the cost of the products exported, is to lock the trading margins agreed with the foreign clients. Internal policy limits the volume of derivative contracts to the volume of products exported.

The volume of hedge executed for the exports occurring between January and December 2010 represented 52.7% of the total exported by Petrobras Distribuidora. The settlements of the operations that matured between January 1 and December 31, 2010 generated a positive result for the Company of US$6.

The over the counter contract is reflected at fair value as either assets or liabilities on the Company’s consolidated balance sheets recognizing gains or losses in earnings, using market to market accounting, in the period of change.

b) Foreign currency risk management (Continued)

As of December 31, 2010, the Company had the following foreign currency derivative contracts, not designated as hedging accounting, that were entered into:

Foreign Currency	Notional Amount

Sell USD / Pay BRL	(8)

Cash flow hedge

In September 2006, the Company contracted a hedge known as a cross currency swap for coverage of the bonds issued in Yens in order to fix the Company’s costs in this operation in dollars. In a cross currency swap there is an exchange of interest rates in different currencies. The exchange rate of the Yen for the US dollar is fixed at the beginning of the transaction and remains fixed during its existence. The Company does not intend to settle these contracts before the end of the term.

The Company has elected to designate its cross currency swap as cash flow hedges. Both at the inception of a hedge and on an ongoing basis, a cash flow hedge must be expected to be highly effective in achieving offsetting cash flows attributable to the hedged risk during the term of the hedge. Derivative instruments designated as cash flow hedges are reflected as either assets or liabilities on the Company’s consolidated balance sheets. Change in fair value, to the extent the hedge is effective, is reported in accumulated other comprehensive income until the cash flows of the hedged item occurs.

Effectiveness tests are conducted quarterly in order to measure how the changes in the fair value or the cash flow of the hedged items are being absorbed by the hedge mechanisms. The effectiveness calculation indicated that the cross currency swap is highly effective in offsetting the variation in the cash flows of the bonds issued in Yens.

Average Pay Rate (USD)	5.69	US$298
Average Receive Rate (JPY)	2.15	JPY$35,000

c) Embedded derivatives

Derivatives embedded within other financial instruments or other host contracts are treated as separate derivatives when they have a price based on an underlying that is not clearly and closely related to the asset being sold or purchased. The assessment is made only at the inception of the contracts. Such derivatives are separately from the host contract and recognized at fair value with changes in fair value recognized in earnings.

Sale of ethanol

Petrobras through its subsidiary, Petrobras International Finance (PifCo), entered into a sales contract of 143,000 m³ per year of ethanol for ten years subject to renegotiation of prices and termination after the first five years. The sales price formula is based on both quotations: ethanol and naphtha.

Naphtha is an extraneous underlying to the cost and fair value of the asset being sold. The embedded derivative was bifurcated from the host contract and recognized at fair value through earnings.

Forward Contract	Notional amount in thousand m3	Fair Value	VAR	Maturity
Long position	715	US$32	1	2016

d) Interest rate risk management

The Company’s interest rate risk is a function of the Company’s long-term debt and to a lesser extent, its short-term debt. The Company’s foreign currency floating rate debt is principally subject to fluctuations in LIBOR and the Company’s floating rate debt denominated in Reais is principally subject to fluctuations in the Brazilian long-term interest rate (TJLP) as fixed by the National Monetary Council. The Company currently does not utilize derivative financial instruments to manage its exposure to fluctuations in interest rates.

20. Financial Instruments

In the normal course of its business activities, the Company acquires various types of financial instruments.

a) Concentrations of credit risk

Substantial portions of the Company’s assets including financial instruments are located in Brazil while substantially all of the Company’s revenues and net income are generated in Brazil. The Company’s financial instruments that are exposed to concentrations of credit risk consist primarily of its cash and cash equivalents, the Petroleum and Alcohol account, trade receivables and futures contracts.

The Company takes several measures to reduce its credit risk to acceptable levels. All cash and cash equivalents in Brazil are maintained with major banks. Time deposits in U.S. dollars are placed with creditworthy institutions in the United States. Additionally, all of the Company’s available-for-sale securities and derivative contracts are either exchange traded or maintained with creditworthy financial institutions. The Company monitors its credit risk associated with trade receivables by routinely assessing the creditworthiness of its customers. At December 31, 2010 and December 31, 2009, the Company’s trade receivables were primarily maintained with large distributors.

b) Fair value

Fair values are derived either from quoted market prices where available, or, in their absence, the present value of expected cash flows. Fair values reflect the cash that would have been either received or paid if the instruments were settled at year end in an arms length transaction between willing parties. Fair values of cash and cash equivalents, trade receivables, the Petroleum and Alcohol account, short-term debt and trade payables approximate their carrying values.

The fair values of other long-term receivables and payables do not differ materially from their carrying values.

The Company’s debt including project financing obligations, resulting from Codification TOPIC 810 consolidation amounted to US$60,471, at December 31, 2010, and US$49,041 at December 31, 2009, and had estimated fair values of US$62,752 and US$48,804, respectively.

21. Segment Information (Continued)

The items that cannot be attributed to the other departments, notably those linked to corporate financial management, the overheads related to central administration and other expenses, including actuarial expenses related to the pension and healthcare plans for retired employees and pensioners, are allocated in the corporate agencies group. The business dealings with biofuels, represented mainly by the operations of Petrobras Biocombustível are also included in this group.

The accounting information per business segment was prepared based on the assumption of controllability, for the purpose of attributing to the business departments only those items over which these departments have effective control.

In the computation of the results by business segment, transactions carried out with third parties and the transfers between the business departments are considered and they are valued by internal transfer prices defined between the departments using calculation methodologies based on market parameters.

(1) The segments “Refining, Transportation and Marketing” and “Gas and Power” were previously reported as “Supply” and “Gas and Energy”, respectively, without representing changes in the factors used to identify the included activities, and in the amounts previously reported.

The main criteria used to record the results and assets by business segments are summarized as follows:

• Net operating revenues: these were considered to be the revenues from sales to third parties, plus revenues between the business segments, based on the internal transfer prices established by the areas;

• Costs and expenses includes the costs of products and services sold, calculated per business segment, based on the internal transfer price and the other operating costs of each segment, as well as operating expenses, based on the expenses actually incurred in each segment;

• Financial results are allocated to the corporate group;

• Assets: covers the assets relating to each segment.

Debt of the electricity sector

The Company has receivables from the electricity sector related to the supplying of fuel to thermoelectric power stations located in the north region of Brazil. Part of the cost of supplying fuel to the thermoelectric power stations is supported by the funds of the Fuel Consumption Account (CCC) - Isolated Systems, the management of which is legally under the jurisdiction of Eletrobrás.

The Company also supplies fuel to Independent Power Producers (PIE), companies created for the purpose of producing power exclusively for Amazônia Distribuidora S. A. (ADESA), a direct subsidiary of Eletrobrás, whose payments for supplying fuel depend directly on the forwarding of funds from ADESA to these Independent Power Producers.

The balance of the receivables at December 31, 2010 was US$1,887 (US$ 1,153 at December 31, 2009), presented in non-current assets and classified as receivables from related parties of which US$1,424 was overdue.

The Company has made systematic collections from the debtors and Eletrobrás, and partial payments have been made.

23. Accounting for Suspended Exploratory Wells

The Company’s accounting for exploratory drilling costs is governed by Codification Topic 932 – Extractive Activities – Oil and Gas. Costs the Company has incurred to drill exploratory wells that find commercial quantities of oil and gas are carried as assets on its balance sheet under the classification “Property, plant and equipment” as unproved oil and gas properties. Each year, the Company writes-off the costs of these wells that have not found sufficient proved reserves to justify completion as a producing well, unless: (1) the well is in an area requiring major capital expenditure before production can begin; and (2) additional exploratory drilling is under way or firmly planned to determine whether the capital expenditure is justified.

As of December 31, 2010, the total amount of unproved oil and gas properties was US$7,846, and of that amount US$4,838 (US$2,911 of which related to projects in Brazil) represented costs that had been capitalized for more than one year, which generally are a result of: (1) extended exploratory activities associated with offshore production; and (2) the transitory effects of deregulation in the Brazilian oil and gas industry, as described below.

In 1998, the Company’s government-granted monopoly ended and the Company signed concession contracts with the Agência Nacional de Petróleo (National Petroleum Agency, or ANP) for all of the areas the Company had been exploring and developing prior to 1998, which consisted of 397 concession block. Since 1998, the ANP has conducted competitive bidding rounds for exploration rights, which has allowed the Company to acquire additional concession blocks. After a concession block is found to contain a successful exploratory well, the Company must submit an “Evaluation Plan” to the ANP for approval. This Evaluation Plan details the drilling plans for additional exploratory wells. An Evaluation Plan is only submitted for those concession areas where technical and economic feasibility analyses on existing exploration wells evidence justification for completion of such wells. Until the ANP approves the Evaluation Plan, the drilling of additional exploratory wells cannot commence. If companies do not find commercial quantities of oil and gas within a specific time period, generally 4-6 years depending on the characteristics of the exploration area, then the concession block must be relinquished and returned to the ANP. Because the Company was required to assess a large volume of concession blocks in a limited time frame even when an exploratory well has found sufficient reserves to justify completion and additional wells are firmly planned, finite resources and expiring time frames in other concession blocks have dictated the timing of the planned additional drilling.

23. Accounting for Suspended Exploratory Wells (Continued)

Of the US$4,838 for 84 projects that include wells suspended for more than one year since the completion of drilling, approximately US$1,243 are related to wells in areas for which drilling was under way or firmly planned for the near future and that the Company has submitted an “Evaluation Plan” to the ANP for approval and approximately US$2,416 incurred in costs for activities necessary to assess the reserves and their potential development.

The US$ 4,838 of suspended wells cost capitalized for a period greater than one year as of December 31, 2010, represents 150 exploratory wells and the table below contains the aging of these costs on a well basis:

24. Subsequent Events

Raising of funds for PifCo

On January 27, 2011, the Petrobras International Finance Company (PifCo) concluded the issuing of US$6 billion in Global Notes on the international capital market, with maturity on January 27, 2016, 2021 and 2041, interest rates of 3.875%, 5.375% and 6.750% p.a., respectively, and half-yearly payment of interest as from July 27, 2011.The capital raised will be used for corporate purposes and the financing of the investments established in the 2010-2014 Business Plan, and an appropriate capital structure and the level of financial leverage will be maintained in line with the Company’s goals.

This financing had issuing costs estimated at approximately US$18, a discount of US$21 and effective interest rates of 4.01%, 5.44% and 6.84% p.a., respectively. Global Notes constitute unsecured, unsubordinated obligations for PifCo and have the complete, unconditional guarantee of Petrobras.

Purchase option for Companhia Mexilhão do Brasil (CMB) - Project Mexilhão

On January 12, 2011, Petrobras exercised its purchase option for the shares of SPE Companhia Mexilhão do Brasil and now guarantees the financing taken out by the SPE from BNDES (National Bank of Economic and Social Development).

Merger of Comperj Petroquímicos Básicos S.A. (UPB) and Comperj PET S.A. (PET) into Petrobras

On January 31, 2011, the General Shareholders’ Meeting of Petrobras approved the merger of Comperj Petroquímicos Básicos S.A. and Comperj PET S.A. into its equity, without a capital increase. With the merger of these companies, the corporate structure of Comperj will be simplified, minimizing costs and favoring reallocation of investments.

Special participation in the Albacora, Carapeba, Cherne, Espadarte, Marimbá, Marlim, Marlim Sul, Namorado, Pampo and Roncador Fields- Campos Basin

This special participation was established by Brazilian Petroleum Law 9478/97 and is paid as a form of compensation for oil production activities and is levied on high volume production fields. The method used by Petrobras to calculate the special participation due for the abovementioned fields is based on a legally legitimate interpretation of Ordinance 10 of January 14, 1999, approved by the National Petroleum Agency (ANP).

Special participation in the Albacora, Carapeba, Cherne, Espadarte, Marimbá, Marlim, Marlim Sul, Namorado, Pampo and Roncador Fields- Campos Basin (Continued)

Petrobras received notice from ANP, which instituted an administrative process and established payment of new sums of money considered to be owed for the period between the first quarter of 2005 and the first quarter of 2010, referring to amounts that had been underpaid by the concessionaire, totaling R$ 365 (principal, without fine and interest).

On February 22, 2011, Petrobras filed for a hearing for dismissal of the aforementioned official notification. If ANP’s administrative decision is maintained, Petrobras shall evaluate the possibility of a court suit to suspend and annul the collection of the differences of the special participation.

If the ANP’s administrative decision is maintained, Petrobras would consider legal action to suspend and cancel the charge of the differences of the special participation.

SUPPLEMENTARY INFORMATION ON OIL AND GAS EXPLORATION AND

PRODUCTION (UNAUDITED)

Expressed in Millions of United States Dollars

(except when specifically indicated)

In accordance with Codification Topic 932 - Extractive Activities – Oil and Gas, this section provides supplemental information on oil and gas exploration and producing activities of the Company. The information included in items (i) through (iii) provides historical cost information pertaining to costs incurred in exploration, property acquisitions and development, capitalized costs and results of operations. The information included in items (iv) and (v) present information on Petrobras’ estimated net proved reserve quantities, standardized measure of estimated discounted future net cash flows related to proved reserves, and changes in estimated discounted future net cash flows.

Beginning in 1995, the Federal Government of Brazil undertook a comprehensive reform of the country’s oil and gas regulatory system. On November 9, 1995, the Brazilian Constitution was amended to authorize the Federal Government to contract with any state or privately-owned company to carry out the activities related to the upstream and downstream segments of the Brazilian oil and gas sector. This amendment eliminated Petrobras’ effective monopoly. The amendment was implemented by the Oil Law, which liberated the fuel market in Brazil beginning January 1, 2002.

The Oil Law established a regulatory framework ending Petrobras’ exclusive agency and enabling competition in all aspects of the oil and gas industry in Brazil. As provided in the Oil Law, Petrobras was granted the exclusive right for a period of 27 years to exploit the petroleum reserves in all fields where the Company had previously commenced production. However, the Oil Law established a procedural framework for Petrobras to claim exclusive exploratory (and, in case of success, development) rights for a period of up to three years with respect to areas where the Company could demonstrate that it had “established prospects”. To perfect its claim to explore and develop these areas, the Company had to demonstrate that it had the requisite financial capacity to carry out these activities, alone or through financing or partnering arrangements.

The adoption of the SEC rules seeking to modernize the supplemental oil and gas disclosures and the FASB’s issuance of the Accounting Standards Update nº 2010-03, “Oil and Gas Reserve Estimation and Disclosure”, generated no material impact to the Company’s consolidated financial statements other than additional disclosures as discussed in the Note 2(n).

The “International” geographic area includes activities in South America, which includes Argentina, Colombia, Ecuador, Peru, Uruguai and Venezuela; North America, which includes Mexico and the United States of America; Africa, which includes Angola, Lybia, Namibia, Nigeria, and Tanzania, and Others, which includes India, Iran, Portugal, Cuba, New Zealand, Australia and Turkey. The equity investments are composed of Venezuelan companies involved in exploration and production activities.

iv) Reserve quantities information

The Company’s estimated net proved oil and gas reserves and changes thereto for the years 2010, 2009 and 2008 are shown in the following table. Proved reserves are estimated by the Company’s reservoir engineers in accordance with the reserve definitions prescribed by the Securities and Exchange Commission.

Proved oil and gas reserves are those quantities of oil and gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations—prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. The project to extract the hydrocarbons must have commenced or the operator must be reasonably certain that it will commence the project within a reasonable time.

Developed oil and gas reserves are reserves of any category that can be expected to be recovered: (i) through existing wells with existing equipment and operating methods or in which the cost of the required equipment is relatively minor compared to the cost of a new well; and (ii) through installed extraction equipment and infrastructure operational at the time of the reserves estimate if the extraction is by means not involving a well.

In some cases, substantial new investments in additional wells and related facilities will be required to recover these proved reserves. Due to the inherent uncertainties and the limited nature of reservoir data, estimates of reserves are subject to change as additional information becomes available.

Bolivian proved reserves were not classified as such in 2009 due to the new Bolivian Constitution, which restrict the disclosure of estimated reserves for properties under its authority. The initial balance of Bolivian proved reserves for 2009 is adjusted under the line item “Revisions of previous estimates”.

(v) Standardized measure of discounted future net cash flows relating to proved oil and gas quantities and changes therein

The standardized measure of discounted future net cash flows, related to the above proved oil and gas reserves, is calculated in accordance with the requirements of Codification Topic 932 – Extractive Activities – Oil and Gas. Estimated future cash inflows from production in Brazil and International segments are computed by applying the average price during the 12-month period prior to the ending date of the period covered by the report, determined as an unweighted arithmetic average of the first-day-of-the-month price for each month within such period, unless prices are defined by contractual arrangements, excluding escalations based upon future conditions based upon the Company’s internal pricing methodology for oil and gas to year-end quantities of estimated net proved reserves. Future price changes are limited to those provided by contractual arrangements in existence at the end of each reporting year. Future development and production costs are those estimated future expenditures necessary to develop and produce year-end estimated proved reserves based on year-end cost indicators, assuming continuation of year-end economic conditions. Estimated future income taxes are calculated by applying appropriate year-end statutory tax rates. These rates reflect allowable deductions and are applied to estimated future pre-tax net cash flows, less the tax basis of related assets. Discounted future net cash flows are calculated using 10% midperiod discount factors. This discounting requires a year-by-year estimate of when the future expenditures will be incurred and when the reserves will be produced.

The arbitrary valuation prescribed under Codification Topic 932 – Extractive Activities – Oil and Gas requires assumptions as to the timing and amount of future development and production costs. The calculations are made as of December 31 each year and should not be relied upon as an indication of Petrobras’ future cash flows or the value of its oil and gas reserves.

Report of Independent Registered Public Accounting Firm

The Executive Board and Stockholder of

Petrobras International Finance Company

We have audited the accompanying consolidated balance sheets of Petrobras International Finance Company and subsidiaries (“PifCo” or “the Company”) as of December 31, 2010 and 2009, and the related consolidated statements of operations, changes in stockholder’s deficit and cash flows for each of the years in the three-year period ended December 31, 2010. We also have audited the Company’s internal control over financial reporting as of December 31, 2010, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on these consolidated financial statements, and an opinion on the Company's internal control over financial reporting based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the consolidated financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall consolidated financial statements presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Table of Contents

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of consolidated financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the consolidated financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Petrobras International Finance Company and subsidiaries as of December 31, 2010 and 2009, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2010, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, Petrobras International Finance Company and subsidiaries maintained, in all material respects, effective internal control over financial reporting as of December 31, 2010, based on criteria established in Internal Control-Integrated Framework issued by COSO.

Petrobras International Finance Company and Subsidiaries

(A wholly-owned subsidiary of Petróleo Brasileiro S.A. - Petrobras)

Notes to the Consolidated Financial Statements

Years Ended December 31, 2010, 2009 and 2008

(In thousand of U.S. dollars)

1. The Company and its Operations

Petrobras International Finance Company - (“PifCo” or the “Company”) was incorporated in the Cayman Islands on September 24, 1997 and operates as a wholly-owned subsidiary of Petróleo Brasileiro S.A. - (“Petrobras”).

PifCo purchases crude oil and oil products from Petrobras to hold in inventory and for sale outside Brazil. Additionally, the Company sells and purchases crude oil and oil products to and from third parties and related parties, mainly outside Brazil. PifCo also purchases crude oil and oil products from third parties and sells to Petrobras under terms that allow payment in up to approximately 30 days, without a premium. Prior to April 2010, Petrobras paid for shipments of crude oil and oil products from PifCo over a period of up to 330 days, including a premium that was recognized on a deferred payment basis.

Accordingly, intercompany activities and transactions, and therefore the Company's financial position and results of operations, are affected by decisions made by Petrobras. Commercial operations, including those with Petrobras, are carried out under normal market conditions and at commercial prices. PifCo also engages in international capital market borrowings as a part of Petrobras’ financial and operating strategy.

PifCo will gradually reduce both its sales of crude oil and oil products to Petrobras and its sales of crude oil and oil products to third parties, and will eventually cease these commercial operations altogether. At that time, PifCo will become a finance subsidiary functioning as a vehicle for Petrobras to raise capital for its operations outside of Brazil through the issuance of debt securities in the international capital markets, among other means. Petrobras’ support of PifCo’s debt obligations has been and will continue to be made through unconditional and irrevocable guaranties of payment.

The following is a brief description of each of the Company’s wholly-owned subsidiaries:

Petrobras Singapore Private Limited

Petrobras Singapore Private Limited (“PSPL”), based in Singapore, was incorporated in April 2006 to trade crude oil and oil products in connection with trading activities in Asia.

In 2008, PSPL took a 50% participation in PM Bio Trading Private Limited, a joint venture with Mitsui & Co. LTD established in Singapore to trade ethanol and to perform other related activities with a main focus in the Japanese market. PM Bio Trading Private Limited is scheduled to commence its operations by 2012.

2. Basis of Financial Statement Presentation (Continued)

(h) Prepaid expenses

Prepaid expenses are exclusively comprised of deferred financing costs associated with the Company's debt issuance and are being amortized over the terms of the related debt. The unamortized balance of deferred financing costs was US$ 56,030 and US$ 67,730 as of December 31, 2010 and 2009, respectively.

(i) Property and equipment

Property and equipment are stated at cost and are depreciated according to their estimated useful lives.

(j) Current and long-term liabilities

These are stated at known or estimated amounts including, when applicable, accrued interest.

(k) Unearned income

Unearned income represents the unearned premium charged by the Company to Petrobras and Alberto Pasqualini - Refap S.A. (“Refap”) up to March 2010 to compensate for its financing costs. The premium is billed to Petrobras and Refap at the same time the related product is sold, and is deferred and recognized into earnings as a component of financial income on a straight-line basis over the collection period, which ranges from 120 to 330 days, in order to match the premium billed with the Company’s financial expense. The unearned income is classified within accounts receivable.

(l) Revenues, costs, income and expenses

For all third party and related party transactions, revenues are recognized in accordance with the U.S. SEC’s Staff Accounting Bulletion 104 - Revenue Recognition. Crude oil and oil products revenues are recognized on an accrual basis when persuasive evidence of an arrangement exists in the form of a valid contract, delivery has occurred or title has transferred, the price is fixed or determinable and collectability is reasonably assured. Costs are recognized when incurred. Income and expenses include financial interest and charges, at official rates or indexes, relating current and non-current assets and liabilities and, when applicable, the effects arising from the adjustment of assets to market or realizable value.

Purchases and sales of inventory with the same counterparty (buy/sell arrangements) are combined and recorded on a net basis and reported in “Cost of sales” on the Consolidated Statements of Operations.

(l) Revenues, costs, income and expenses (Continued)

The principal commercial transactions of the Company consist of:

Imports - the Company buys from suppliers outside Brazil (mainly from third-parties) and sells to Petrobras and its Brazilian subsidiaries.

Exports - the Company buys from Petrobras and sells to customers outside Brazil.

Off-shore - the Company buys and sells mainly outside of Brazil, in transactions with third-parties and related parties.

(m) Accounting for derivatives and hedging activities

The Company applies Codification Topic 815 - Derivatives and Hedging, together with its amendments and interpretations, referred to collectively herein as “ASC Topic 815”. These rules require that all derivative instruments be recorded in the balance sheet of the Company as either an asset or a liability and measured at fair value. ASC Topic 815 requires that changes in the derivative’s fair value be recognized in the income statement unless specific hedge accounting criteria are met; and the Company designates. For derivatives designated as accounting hedges, fair value adjustments are recorded either in the income statements or “Accumulated other comprehensive income”, a component of shareholders’ equity, depending upon the type of accounting hedge and the degree of hedge effectiveness.

The Company uses derivative financial instruments, not designated as hedge accounting, to mitigate the risk of unfavorable price movements for crude oil and oil products purchases. These instruments are marked-to-market with the associated gains or losses recognized as “Financial income” or “Financial expense”.

The Company may also use non-hedging derivatives to mitigate the risk of unfavorable exchange-rate movements on its foreign currency-denominated funding. Gains and losses from changes in the fair value of these contracts are recognized as “Financial income” or “Financial expense”.

The Company may also use hedging derivatives to protect exchange of interest rates in different currencies. These hedging derivatives used as well as the risk being hedged are accounted for a cash flow model. Under this model, the gains and losses associated with the derivative instruments are deferred and recorded in “Accumulated other comprehensive income” until such time as the hedged transaction impacts earnings, with the exception of any hedge ineffectiveness; which is recorded directly in the statements of operations.

(n) Recently adopted accounting standards

Transfers and Servicing (ASC 860), Accounting for Transfers of Financial Assets (ASU 2009-16)

The FASB issued ASU 2009-16 in December 2009. This standard removes the concept of a Qualifying Special Purpose Entity (“QSPE”) and the exception for QSPE consolidation and clarifies the requirements for financial asset transfers eligible for sale accounting. ASU 2009-16 was adopted on January 1, 2010, and did not impact the Company’s results of operations, financial position or liquidity.

Consolidation (ASC 810), Improvements to Financial Reporting by Enterprises Involved With Variable Interest Entities (ASU 2009-17)

The FASB issued ASU 2009-17 in December 2009. This standard became effective for the Company January 1, 2010. ASU 2009-17 requires the enterprise to qualitatively assess if it is the primary beneficiary of a variable-interest entity (“VIE”), and, if so, the VIE must be consolidated. Additionally, this Statement requires continuous assessments of whether an enterprise is the primary beneficiary of a VIE. ASU 2009-17 was adopted on January 1, 2010, and did not impact the Company’s results of operations, financial position or liquidity.

Receivables (Topic 310), Disclosures about the Credit Quality of Financing Receivables and the Allowance for Credit Losses (ASU 2010-20)

The ASU 2010-20 enhance the disclosures required for financing receivables and allowances for credit losses under FASB Accounting Standards Codification 310, Receivables.

(b) Purchase option - Platforms

The Company has maintained the right to exercise a call option on the existing Subchartered Asset Option Agreement granted by PNBV, and has maintained an obligation to purchase the vessels in the event that PNBV exercises its Put Option, upon the occurrence of an event of default, under the same Option Agreement, for Platforms P-8, P-15, P-32. PifCo also has an obligation to purchase these platforms after the expiration of the Charters.

In relation to P-47, PifCo has maintained the right to exercise a call option on the existing Subchartered Asset Option Agreement granted by PNBV, and has maintained an obligation to purchase the vessel in the event that PNBV exercises its Put Option, upon the occurrence of an event of default or of the expiration of the Charter.

PifCo may designate any affiliate or subsidiary to perform its obligations under this agreement.

(c) Loan agreements

The Company’s outstanding position at December 31, 2010 in irrevocable letters of credit was US$ 93,572, as compared to US$ 556,162 at December 31, 2009, supporting crude oil and oil products imports and services.

Additionally, the Company had standby committed facilities available in the amount of US$ 720,682, (US$ 518,500 at December 31, 2009) which are not committed to any specific use. PifCo has not drawn down amounts related to these facilities and does not have a scheduled date for the drawdown.

12. Derivative Instruments, Hedging and Risk Management Activities

PifCo’s policy for the risk management of the price of oil and oil products consists basically in protecting the margins in certain specific short-term positions. Future contracts, swaps and options are the instruments used in these economic hedge operations which are tied to actual physical transactions. Positive and negative results are offset by the reverse results of the actual physical market transaction and they are recorded in the statement of operations as financial income and financial expense. The Company’s derivative instruments are recorded in the consolidated balance sheet at their fair value.

12. Derivative Instruments, Hedging and Risk Management Activities (Continued)

For exchange-traded contracts, fair value is based on quoted market prices. For non-exchange traded contracts, fair value is based on dealer quotes, pricing models or quoted prices for instruments with similar characteristics. The transaction price is used as the initial fair value of the contracts.

Commodity derivative contracts are reflected at fair value as either assets or liabilities on the Company’s consolidated balance sheets recognizing gain or losses in earnings, using marked-to-market accounting, in the period of change.

As of December 31, 2010 and 2009, the Company had the following outstanding commodity derivative contracts:

	Notional amount in
Commodity Contracts	thousands of bbl* as of
Maturity 2011	2010	2009
Futures and Forwards contracts	(2,857)	(3,447)
Options contracts	(130)	-

* A negative notional amount represents a sale position.

Cash Flow Hedge

In September 2006, the Company contracted a hedge known as a cross currency swap for coverage of the bonds issued in Yen in order to fix the Company’s costs in this operation in dollars. In a cross currency swap there is an exchange of interest rates in different currencies. The exchange rate of the Yen to the U.S. dollar was fixed at the beginning of the transaction and has remained fixed since that time. The Company does not intend to settle these contracts before the end of their terms.

The Company has elected to designate its cross currency swap as cash flow hedge. Both at the inception of a hedge and on an ongoing basis, a cash flow hedge must be expected to be highly effective in achieving offsetting cash flows attributable to the hedged risk during the term of the hedge. Derivative instruments designated as cash flow hedges are reflected as either assets or liabilities on the Company’s consolidated balance sheets. Change in fair value, to the extent the hedge is effective, is reported in accumulated other comprehensive income until the cash flows of the hedged item occurs.

Cash Flow Hedge (Continued)

Effectiveness tests are conducted quarterly in order to measure how the changes in the fair value or the cash flow of the hedge items are being absorbed by the hedge mechanisms. The effectiveness calculation indicated that the cross currency swap is highly effective in offsetting the variation in the cash flow of the bonds issued in Yen.

As of December 31, 2010, the Company had entered into the following cross currency swap:

Cross Currency Swaps
		Notional Amount
Maturing in 2016	%	(in thousand JPY)
Fixed to fixed		35,000,000
Average Pay Rate (USD)	5.69
Average Receive Rate (JPY)	2.15

At December 31, 2010, the cross currency swap and the portfolio for commercial operations, as well as the hedges for their protection through derivatives for oil and oil products, presented a maximum estimated loss per day (VAR – Value at Risk), calculated at a reliability level of 95%, of approximately US$ 5,572 and US$ 9,786, respectively.

The effect of derivative instruments on the statement of financial position for the year ended December, 31 2010 and 2009 was as follows:

PifCo had written put options in the past that allows the holder of the options to sell a floating number of heavy fuel oil volumes at a minimum price of US$14/barrel. Such option had served as an economic hedge on related future sales of receivables under the structured finance export prepayment program; the intent of which was to ensure that physical barrels delivered under the structured finance export prepayment program generate sufficient cash proceeds to repay related financial obligations. Given the low strike price relative to the market the fair value of these options is immaterial at December 31, 2010 and 2009.

Embedded Derivatives

The procedures for identifying derivative instruments in contracts aim at timely recognition, control and adequate accounting handling to be employed.

The contracts with possible clauses for derivative instruments or securities to be realized are communicated before they are signed, so that there is orientation with respect to the eventual performance of effectivity tests, the establishment of the accounting policy to be adopted and the methodology for calculation of the fair value.

12. Derivative Instruments, Hedging and Risk Management Activities (Continued)

The embedded derivatives identified in the year were:

Sale of Imported Petroleum

Sales agreements for imported petroleum entered into between Petrobras Singapore Private Limited - PSPL and Refinaria de Petróleo Riograndense S.A.

The transaction consists of sale of petroleum, whose main characteristics reside in the fact that the prices to be paid on a future date are fixed at the time of the signing of the contracts, in contrast to other transactions of the same nature where the settlement prices are observed on the dates of delivery of the products, which incontestably defines the existence of a short position for a petroleum futures contract.

	Notional amount in thousands of bbl* as of
		Fair Value	VaR	Maturity
Forwards contract
Short position	400	2,316	1,080	2011

The identified embedded derivative was valued at fair value through profit and loss and classified at level 1 in the fair value hierarchy.

Sale of Ethanol

Sales agreements for hydrous ethanol entered into between PifCo and Toyota Tsusho Corporation.

The transaction consists of sale of hydrous ethanol through a price formula defined at the time of signing the contract. The definition of price for each shipment of hydrous ethanol delivered in this contract involves two quotations of distinct references: ethanol and naphtha.

The contract establishes the beginning of delivery of shipments of alcohol in 2012 for a period of 10 years. However, as there is a contractual clause that permits renegotiation of prices and termination by any one of the parties after five years, if a new agreement is not reached, we consider the term of only five years as a firm contractual commitment for purposes of calculating the value of the embedded derivative financial instrument.

12. Derivative Instruments, Hedging and Risk Management Activities (Continued)

The basic defined contractual quantity is 143,000 m³ per year.

The price formula in question uses as one of its references the quotation of a commodity that does not maintain a strict cost or market value relationship with the product transacted in the contract. Accordingly, the portion referring to the embedded derivative should be isolated from the original contract and recorded in the financial statements following the same rules applicable to the other derivative financial instruments.

The table below presents the fair value and the value at risk (VaR) of the embedded derivative for the year:

	Notional amount in thousands of m3* as of
		Fair Value	VaR	Maturity
Forwards contracts
Long position	715	32,081	992	2016

The derivative was valued at fair value through profit and loss and classified at level 3 in the fair value hierarchy.

The gains obtained are presented in the Statements of Operations as financial income.

Fair Value

Fair values are derived either from quoted market prices available, or, in their absence, the present value of expected cash flows. The fair values reflect the cash that would have been received or paid if the instruments were settled at year end. Fair values of cash and cash equivalents, trade receivables, short-term debt, short-term portion of long-term debt and trade payables approximate their carrying values.

The Company’s long-term asset related to the export prepayment program was US$ 194,440 and US$ 263,480 at December 31, 2010 and 2009, respectively, and had fair values of US$ 205,800 and US$ 270,500, respectively.

The disclosure requirements of Codification Topic 820 were applied to the Company’s derivative instruments and certain marketable securities recognized in accordance with Codification Topic 320.

12. Derivative Instruments, Hedging and Risk Management Activities (Continued)

The Company’s commodities derivatives, marketable securities and embedded derivative of sale of imported petroleum fair values were recognized in accordance with exchanged quoted prices as the balance sheet date for identical assets and liabilities in active markets, and, therefore, were classified as level 1.

The fair values of cross currency swaps were calculated using observable interest rates in JPY and USD for the full term of the contracts, and, therefore, were classified as level 2.

The fair value of embedded derivative of sale of ethanol was determined based on practices used on the market, where the difference between the spreads for naphtha and ethanol is calculated. The values of the parameters used in the calculation were obtained from the quotations for market price for ethanol and naphtha on the CBOT (Chicago Board of Trade) future market on the last working day of the period of the financial statements, and, therefore, was classified as level 3.

The fair value hierarchy for our financial assets and liability accounted for at fair value on a recurring basis at December 31, 2010, was:

				December 31,

SECTION 4.Independent Obligation.  The obligations of the Guarantor  hereunder are independent of the Issuer’s obligations under the 2016 Notes and the Indenture.  The Trustee, on behalf of the Noteholders, may neglect or forbear to enforce payment under the Indenture and the 2016 Notes, without in any way affecting or impairing the liability of the Guarantor  hereunder.  The Trustee shall not be obligated to exhaust recourse or remedies against the Issuer to recover payments required to be made under the Indenture nor take any other action against the Issuer before being entitled to payment from the Guarantor  of all amounts contemplated in Section 2 hereof owed hereunder or proceed against or have resort to any balance of any deposit account or credit on the books of the Trustee in favor of the Issuer or in favor of the Guarantor.  Without limiting the generality of the foregoing, the Trustee shall have the right to bring a suit directly against the Guarantor, either prior or subsequent to or concurrently with any lawsuit against, or without bringing suit against, the Issuer.

 (c)       Maintenance of Office or Agency.  So long as any of the 2016 Notes are outstanding, the Guarantor will maintain in the Borough of Manhattan, The City of New York, an office or agency where notices to and demands upon the Guarantor  in respect of this Guaranty  may be served, and the Guarantor  will not change the designation of such office without prior written notice to the Trustee and designation of a replacement office in the same general location.

(d)       Ranking.  The Guarantor  will ensure at all times that its obligations under this Guaranty  will constitute the general senior unsecured and unsubordinated obligations of the Guarantor  and will rank pari passu, without any preferences among themselves, with all other present and future senior unsecured and unsubordinated obligations of the Guarantor  (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 the Guarantor under this Guaranty.

(e)        Notice of Defaults.  The Guarantor will give written notice to the Trustee, as soon as is practicable and in any event within ten calendar days after the Guarantor  becomes aware, or should reasonably become aware, of the occurrence of any Default or Event of Default, accompanied by a certificate of an officer of the Guarantor setting forth the details thereof and stating what action the Guarantor proposes to take with respect thereto.

(f)        Limitation on Consolidation, Merger, Sale or Conveyance.  (i) The Guarantor  will not, in one or a series of transactions, consolidate or amalgamate with or merge into any corporation or convey, lease or transfer substantially all of its properties, assets or revenues to any person or entity (other than a direct or indirect Subsidiary of the Guarantor) or permit any person or entity (other than a direct or indirect Subsidiary of the Guarantor) to merge with or into it,  unless:

(B)       the Successor Company (jointly and severally with the Guarantor  unless the Guarantor shall have ceased to exist as part of such merger, consolidation or amalgamation) agrees to indemnify each Noteholder against any tax, assessment or governmental charge thereafter imposed on such Noteholder solely as a consequence of such consolidation, merger, conveyance, transfer or lease with respect to the payment of principal of, or interest on, the 2016 Notes pursuant to this Guaranty;  

(C)       immediately after giving effect to such  transaction, no Event of Default,  and no Default has occurred and is continuing; and

(D)       the Guarantor  has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that such merger consolidation, sale, transfer or other conveyance or disposition and the amendment to this Guaranty comply with the terms of this Guaranty  and that all conditions precedent provided for herein and relating to such transaction have been complied with.

(ii)        Notwithstanding anything to the contrary in the foregoing, so long as no Default or Event of Default shall have occurred and be continuing at the time of such proposed transaction or would result therefrom and the Guarantor has delivered notice of any such transaction to the Trustee (which notice shall contain a description of such merger, consolidation or conveyance): 

(A)       the Guarantor  may merge, amalgamate or consolidate with or into, or convey, transfer, lease or otherwise dispose of all or substantially all of its properties, assets or revenues to a direct or indirect Subsidiary of the Guarantor  in cases when the Guarantor  is the surviving entity in such transaction and such transaction would not have a Material Adverse Effect on the Guarantor  and its Subsidiaries taken as a whole, it being understood that if the Guarantor  is not the surviving entity, the Guarantor shall be required to comply with the requirements set forth in the previous paragraph; or

(B)       any direct or indirect Subsidiary of the Guarantor  may merge or consolidate with or into, or convey, transfer, lease or otherwise dispose of assets to, any person (other than the Guarantor or any of its Subsidiaries or Affiliates) in cases when such transaction would not have a Material Adverse Effect on the Guarantor  and its Subsidiaries taken as a whole; or

(C)       any direct or indirect Subsidiary of the Guarantor may merge or consolidate with or into, or convey, transfer, lease or otherwise dispose of assets to, any direct or indirect Subsidiary of the Guarantor; or

11

(D)       any direct or indirect Subsidiary of the Guarantor  may liquidate or dissolve if the Guarantor  determines in good faith that such liquidation or dissolution is in the best interests of the Guarantor, and would not result in a Material Adverse Effect on the Guarantor  and its Subsidiaries taken as a whole and if such liquidation or dissolution is part of a corporate reorganization of the Guarantor. 

(g)        Negative Pledge.  So long as any 2016 Note remains outstanding, the Guarantor will not create or permit any Lien, other than a Permitted Lien, on any of the Guarantor’s assets to secure (i) any of the Guarantor’s Indebtedness or (ii) the Indebtedness of any other person, unless the Guarantor contemporaneously creates or permits such Lien to secure equally and ratably the Guarantor’s obligations under this Guaranty or the Guarantor provides such other security for the 2016 Notes as is duly approved by the Trustee, at the direction of the Noteholders, in accordance with the Indenture.  In addition, the Guarantor will not allow any of the Guarantor’s Material Subsidiaries to create or permit any Lien, other than a Permitted Lien, on any of the Guarantor’s assets to secure (i) any of the Guarantor’s Indebtedness, (ii) any of the Indebtedness of the Guarantor’s Material Subsidiaries or (iii) the Indebtedness of any other person, unless it contemporaneously creates or permits the Lien to secure equally and ratably the Guarantor’s obligations under this Guaranty or the Guarantor or such Material Subsidiary provides such other security for the 2016 Notes as is duly approved by the Trustee, at the direction of the Noteholders, in accordance with the Indenture.

 (h)       Provision of Financial Statements and Reports.  (i)  The Guarantor  will provide to the Trustee, in English or accompanied by a certified English translation thereof, (A) 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 Reporting GAAP, (B) 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 Reporting GAAP and (C) such other financial data as the Trustee may reasonably request.

(iii)       The Guarantor shall, whether or not it is required to file reports with the SEC, file with the SEC and deliver to the Trustee (for redelivery to all Noteholders) all reports and other information as it would be required to file with the SEC under the Exchange Act if it were subject to those regulations; provided, however, that if the SEC does not permit the filing described in the first sentence of this Section 7(h)(iii), the Guarantor will provide annual and interim reports and other information to the Trustee within the same time periods that would be applicable if the Guarantor were required and permitted to file these reports with the SEC.

12

(iv)       Upon written request of any Holder or The Depository Trust Company (DTC), the reports and other information provided for in this paragraph (h) shall be delivered to DTC representing the Noteholders, at 55 Water Street, 25th Floor, New York, NY, 10041, Attention:  Proxy Department, or such other address as DTC may provide to the Trustee in writing.

SECTION 8.Amendments, Etc.   No amendment or waiver of any provision of this Guaranty  and no consent to any departure by the Guarantor  therefrom shall in any event be effective unless the same shall be in writing and signed by the Trustee and the Guarantor, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given. For the avoidance of doubt, Article IX of the Indenture shall apply to an amendment to this Guaranty to determine whether the consent of Holders is required for an amendment and if so, the required percentage of Holders of the 2016 Notes required to approve the amendment. 

SECTION 9.Indemnity.  The Guarantor agrees to fully indemnify the Trustee and any predecessor Trustee and their agents for, and to hold it harmless against, any and all loss, liability, damages, claims or expense arising out of or in connection with the performance of its duties under this Guaranty, including the costs and expenses of defending itself against any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder except to the extent that any such loss, liability or expense may be attributable to its negligence or bad faith.

SECTION 12.No Waiver; Remedies. No failure on the part of the Trustee to exercise, and no delay in exercising, any right hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right hereunder preclude any other or further exercise thereof or the exercise of any other right.  The remedies herein provided are cumulative and not exclusive of any remedies provided by law.

The Guarantor  shall not have the right to assign its rights hereunder or any interest herein without the prior written consent of all of the Noteholders.

SECTION 14.  Currency Rate Indemnity(a)  The Guarantor  shall (to the extent lawful) indemnify the Trustee and the Noteholders and keep them indemnified against:

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

            (ii)        any deficiency arising or resulting from any variation in rates of exchange between (a) the date as of which the local currency equivalent of the amounts due or contingently due under this Guaranty  or in respect of the 2016 Notes is calculated for the purposes of any bankruptcy, insolvency or liquidation of the Guarantor, and (b) the final date for ascertaining the amount of claims in such bankruptcy, insolvency or liquidation.  The amount of such deficiency shall be deemed not to be increased or reduced by any variation in rates of exchange occurring between the said final date and the date of any bankruptcy, insolvency or liquidation or any distribution of assets in connection therewith.

14

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

(c)      The above indemnities shall constitute separate and independent obligations of the Guarantor  from its obligations hereunder, will give rise to separate and independent causes of action, will apply irrespective of any indulgence granted from time to time and will continue in full force and effect notwithstanding any judgment or the filing of any proof or proofs in any bankruptcy, insolvency or liquidation of the Guarantor for a liquidated sum or sums in respect of amounts due under this Guaranty, or under the Indenture or the 2016 Notes or under any judgment or order.

SECTION 15.Governing Law; Jurisdiction; Waiver of Immunity, Etc. 

(a)This Guaranty shall be governed by, and construed in accordance with, the laws of the State of New York.

(b)The Guarantor  hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of any New York State court or federal court of the United States of sitting in New York City, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Guaranty  or any of the other Transaction Documents to which it is or is to be a party, or for recognition or enforcement of any judgment, and the Guarantor  hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in any such New York State court or, to the extent permitted by law, in such federal court.  The Guarantor agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.  Nothing in this Guaranty  or any other Transaction Document shall affect any right that any party may otherwise have to bring any action or proceeding against the Issuer or the Guarantor, as the case may be, relating to this Guaranty  or any other Transaction Document in the courts of any jurisdiction.

(c)The Guarantor  hereby irrevocably appoints and empowers the New York office of Petróleo Brasileiro S.A., located at 570 Lexington Avenue, 43rd Floor, New York, New York 10022 as its authorized agent (the “Process Agent”) to accept and acknowledge for and on its behalf and on behalf of its property service of any and all legal process, summons, notices and documents which may be served in any such suit, action or proceedings in any New York State court or United States federal  court sitting in the State of New York in the Borough of Manhattan and any appellate court from any thereof, which service may be made on such designee, appointee and agent in accordance with legal procedures prescribed for such courts.  The Guarantor  will take any and all action necessary to continue such designation in full force and effect and to advise the Trustee of any change of address of such Process Agent and; should such Process Agent become unavailable for this purpose for any reason, the Guarantor  will promptly and irrevocably designate a new Process Agent within New York, New York, which will agree

15

to act as such, with the powers and for the purposes specified in this subsection (c).  The Guarantor irrevocably consents and agrees to the service of any and all legal process, summons, notices and documents out of any of the aforesaid courts in any such action, suit or proceeding by hand delivery, to it at its address set forth in Section 10 or to any other address of which it shall have given notice pursuant to Section 10 or to its Process Agent.  Service upon the Guarantor or the Process Agent as provided for herein will, to the fullest extent permitted by law, constitute valid and effective personal service upon it and the failure of the Process Agent to give any notice of such service to the Guarantor shall not impair or affect in any way the validity of such service or any judgment rendered in any action or proceeding based thereon.

(d)The Guarantor irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection that it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Guaranty or any of the other Transaction Documents to which it is or is to be a party in any New York State or federal court.  The Guarantor hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such suit, action or proceeding in any such court.

(e)THE GUARANTOR  HEREBY IRREVOCABLY WAIVES ALL RIGHT  TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS GUARANTY, ANY OF THE TRANSACTION DOCUMENTS, THE ADVANCES OR THE ACTIONS OF ANY NOTEHOLDER IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE OR ENFORCEMENT THEREOF.

(f)This Guaranty  and any other documents delivered pursuant hereto, and any actions taken hereunder, constitute commercial acts by the Guarantor.  The Guarantor  irrevocably and unconditionally and to the fullest extent permitted by law, waives, and agrees not to plead or claim, any immunity from jurisdiction of any court or from any legal process (whether through service of  notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) for itself, the Issuer or any of their  property, assets or revenues wherever located with respect to its obligations, liabilities or any other matter under or arising out of or in connection with this Guaranty, any of the Transaction Documents or any document delivered pursuant hereto, in each case for the benefit of each assigns, it being intended that the foregoing waiver and agreement will be effective, irrevocable and not subject to withdrawal in any and all jurisdictions, and, without limiting the generality of the foregoing, agrees that the waivers set forth in this subsection (f) shall have the fullest scope permitted under the United States Foreign Sovereign Immunities Act of 1976 and are intended to be irrevocable for the purposes of such act.

SECTION 16. Execution in Counterparts. This Guaranty  and each amendment, waiver and consent with respect hereto may be executed in any number of counterparts and by different parties thereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement.  Delivery of an executed counterpart of a signature page to this Guaranty  by telecopier shall be effective as delivery of an original executed counterpart of this Guaranty. 

16

SECTION 17. Entire Agreement. This Guaranty, together with the Indenture and the 2016 Notes, sets forth the entire agreement of the parties hereto with respect to the subject matter hereof.

SECTION 4.Independent Obligation.  The obligations of the Guarantor  hereunder are independent of the Issuer’s obligations under the 2021 Notes and the Indenture.  The Trustee, on behalf of the Noteholders, may neglect or forbear to enforce payment under the Indenture and the 2021 Notes, without in any way affecting or impairing the liability of the Guarantor  hereunder.  The Trustee shall not be obligated to exhaust recourse or remedies against the Issuer to recover payments required to be made under the Indenture nor take any other action against the Issuer before being entitled to payment from the Guarantor  of all amounts contemplated in Section  2 hereof owed hereunder or proceed against or have resort to any balance of any deposit account or credit on the books of the Trustee in favor of the Issuer or in favor of the Guarantor.  Without limiting the generality of the foregoing, the Trustee shall have the right to bring a suit directly against the Guarantor, either prior or subsequent to or concurrently with any lawsuit against, or without bringing suit against, the Issuer.

SECTION 5.Waivers and Acknowledgments.  (a) The Guarantor  hereby unconditionally and irrevocably waives promptness, diligence, notice of acceptance, presentment, demand for performance, notice of nonperformance, default, acceleration, protest or dishonor and any other notice with respect to any of the Guaranteed  Obligations and this Guaranty  and any requirement that the Trustee, on behalf of the Noteholders, protect, secure, perfect or insure any Lien or any property subject thereto or exhaust any right or take any action against the Issuer or any other Person.

(b)        The Guarantor hereby unconditionally and irrevocably waives any right to revoke this Guaranty and acknowledges that this Guaranty is continuing in nature and applies to the Guaranteed Obligations, whether the same are existing now or in the future.

(c)        The Guarantor hereby unconditionally and irrevocably waives (i) any defense arising by reason of any claim or defense based upon an election of remedies by any Noteholder or the Trustee on behalf of the Noteholders that in any manner impairs, reduces, releases or otherwise adversely affects the subrogation, reimbursement, exoneration, contribution or indemnification rights of the Guarantor  or other rights of the Guarantor  to proceed against the Issuer or any other person or entity and (ii) any defense based on any right of set-off or counterclaim against or in respect of the Guaranteed  Obligations of the Guarantor  hereunder.

(d)       The Guarantor  hereby unconditionally and irrevocably waives any duty on the part of the Trustee or any Noteholder to disclose to the Guarantor  any matter, fact or thing relating to the business, condition (financial or otherwise), operations, performance, properties or prospects of the Issuer now or hereafter known by the Trustee or any Noteholder, as applicable.

8

(e)        The Guarantor acknowledges that it will receive substantial direct and indirect benefits from the financing arrangements contemplated by the Transaction Documents and that the waivers set forth in this Section 5 are knowingly made in contemplation of such benefits.

(f)        The recitals contained in this Guaranty shall be taken as the statements of the Issuer and the Guarantor, as applicable, and the Trustee assumes no responsibility for the correctness of the same.  The Trustee makes no representation as to the validity or sufficiency of this Guaranty, of any offering materials, the Indenture or of the 2021 Notes.

(g)        The Guarantor unconditionally and irrevocably waives, to the fullest extent permitted under Brazilian law, any benefit it may be entitled to under Articles 827, 834, 835, 838 and 839 of the Brazilian Civil Code, and under Article 595, caput, of the Brazilian Civil Procedure Code.

SECTION 6.Claims Against the Issuer. The Guarantor hereby unconditionally and irrevocably agrees not to exercise any rights that it may now have or hereafter acquire against the Issuer or any other guarantor that arise from the existence, payment, performance or enforcement of the Guarantor’s obligations under or in respect of this Guaranty or any other Transaction Document, including, without limitation, any right of subrogation, reimbursement, exoneration, contribution or indemnification, or to participate in any claim or remedy of the Trustee, on behalf of the Noteholders, against the Issuer or any other person, whether or not such claim, remedy or right arises in equity or under contract, statute or common law, including, without limitation, the right to take or receive from the Issuer or any other person, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security on account of such claim, remedy or right, unless and until all of the Guaranteed Obligations and all other amounts payable under this Guaranty shall have been paid in full in cash.  If any amount shall be paid to the Guarantor in violation of the immediately preceding sentence at any time prior to the later of (a) the payment in full in cash of the Guaranteed Obligations and all other amounts payable under this Guaranty and (b) the date on which all of the obligations of the Issuer under the Indenture and the 2021 Notes have been discharged in full (the later of such dates being the “Termination Date”), such amount shall be paid over to and received and held by the Trustee in trust for the benefit of the Noteholders, shall be segregated from other property and funds of the Guarantor and shall forthwith be paid or delivered to the Trustee in the same form as so received (with any necessary endorsement or assignment) to be credited and applied to the Guaranteed Obligations and all other amounts payable under this Guaranty, whether matured or unmatured, in accordance with the terms of the Indenture.  If (i) the Guarantor shall make payment to any Noteholder or the Trustee, on behalf of the Noteholders, of all or any part of the Guaranteed Obligations, (ii) all of the Guaranteed Obligations and all other amounts payable under this Guaranty shall have been paid in full in cash and (iii) the Termination Date shall have occurred, then the Trustee, on behalf of the Noteholders, will, at the Guarantor’s written request and expense, execute and deliver to the Guarantor appropriate documents, without recourse and without representation or warranty, necessary to evidence the transfer by subrogation to the Guarantor of an interest in the Guaranteed Obligations resulting from such payment made by the Guarantor pursuant to this Guaranty.

SECTION 7.Covenants. For so long as the 2021 Notes remain outstanding or any amount remains unpaid on the 2021 Notes and the Indenture, the Guarantor will, and will cause each of its Subsidiaries, as applicable, to comply with the terms and covenants set forth below (except as otherwise provided in a duly authorized amendment to this Guaranty as provided herein):

 (c)       Maintenance of Office or Agency.  So long as any of the 2021 Notes are outstanding, the Guarantor will maintain in the Borough of Manhattan, The City of New York, an office or agency where notices to and demands upon the Guarantor  in respect of this Guaranty  may be served, and the Guarantor  will not change the designation of such office without prior written notice to the Trustee and designation of a replacement office in the same general location.

(d)       Ranking.  The Guarantor  will ensure at all times that its obligations under this Guaranty  will constitute the general senior unsecured and unsubordinated obligations of the Guarantor  and will rank pari passu, without any preferences among themselves, with all other present and future senior unsecured and unsubordinated obligations of the Guarantor  (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 the Guarantor under this Guaranty.

(e)        Notice of Defaults.  The Guarantor  will give written notice to the Trustee, as soon as is practicable and in any event within ten calendar days after the Guarantor  becomes aware, or should reasonably become aware, of the occurrence of any Default or Event of Default, accompanied by a certificate of an officer of the Guarantor setting forth the details thereof and stating what action the Guarantor  proposes to take with respect thereto.

(f)        Limitation on Consolidation, Merger, Sale or Conveyance.  (i) The Guarantor  will not, in one or a series of transactions, consolidate or amalgamate with or merge into any corporation or convey, lease or transfer substantially all of its properties, assets or revenues to any person or entity (other than a direct or indirect Subsidiary of the Guarantor) or permit any person or entity (other than a direct or indirect Subsidiary of the Guarantor) to merge with or into it,  unless:

(A)       either the Guarantor  is the continuing entity or the person (the “Successor Company”)  formed by such consolidation or into which the Guarantor is merged or that acquired or leased such property or assets of the Guarantor will assume (jointly and severally with the Guarantor unless the Guarantor shall have ceased to exist as a result of such merger, consolidation or amalgamation), by an amendment to this Guaranty (the form and substance of which shall be previously approved by the Trustee), all of the Guarantor’s obligations under this Guaranty;

10

(B)       the Successor Company (jointly and severally with the Guarantor  unless the Guarantor  shall have ceased to exist as part of such merger, consolidation or amalgamation) agrees to indemnify each Noteholder against any tax, assessment or governmental charge thereafter imposed on such Noteholder solely as a consequence of such consolidation, merger, conveyance, transfer or lease with respect to the payment of principal of, or interest on, the 2021 Notes pursuant to this Guaranty;  

(C)       immediately after giving effect to such  transaction, no Event of Default,  and no Default has occurred and is continuing; and

(D)       the Guarantor  has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that such merger consolidation, sale, transfer or other conveyance or disposition and the amendment to this Guaranty comply with the terms of this Guaranty  and that all conditions precedent provided for herein and relating to such transaction have been complied with.

(ii)        Notwithstanding anything to the contrary in the foregoing, so long as no Default or Event of Default shall have occurred and be continuing at the time of such proposed transaction or would result therefrom and the Guarantor has delivered notice of any such transaction to the Trustee (which notice shall contain a description of such merger, consolidation or conveyance): 

(A)       the Guarantor  may merge, amalgamate or consolidate with or into, or convey, transfer, lease or otherwise dispose of all or substantially all of its properties, assets or revenues to a direct or indirect Subsidiary of the Guarantor  in cases when the Guarantor is the surviving entity in such transaction and such transaction would not have a Material Adverse Effect on the Guarantor  and its Subsidiaries taken as a whole, it being understood that if the Guarantor  is not the surviving entity, the Guarantor  shall be required to comply with the requirements set forth in the previous paragraph; or

(B)       any direct or indirect Subsidiary of the Guarantor  may merge or consolidate with or into, or convey, transfer, lease or otherwise dispose of assets to, any person (other than the Guarantor or any of its Subsidiaries or Affiliates) in cases when such transaction would not have a Material Adverse Effect on the Guarantor  and its Subsidiaries taken as a whole; or

(C)       any direct or indirect Subsidiary of the Guarantor  may merge or consolidate with or into, or convey, transfer, lease or otherwise dispose of assets to, any direct or indirect Subsidiary of the Guarantor; or

11

(D)       any direct or indirect Subsidiary of the Guarantor  may liquidate or dissolve if the Guarantor  determines in good faith that such liquidation or dissolution is in the best interests of the Guarantor, and would not result in a Material Adverse Effect on the Guarantor  and its Subsidiaries taken as a whole and if such liquidation or dissolution is part of a corporate reorganization of the Guarantor. 

(g)        Negative Pledge.  So long as any 2021 Note remains outstanding, the Guarantor will not create or permit any Lien, other than a Permitted Lien, on any of the Guarantor’s assets to secure (i) any of the Guarantor’s Indebtedness or (ii) the Indebtedness of any other person, unless the Guarantor contemporaneously creates or permits such Lien to secure equally and ratably the Guarantor’s obligations under this Guaranty or the Guarantor provides such other security for the 2021 Notes as is duly approved by the Trustee, at the direction of the Noteholders, in accordance with the Indenture.  In addition, the Guarantor will not allow any of the Guarantor’s Material Subsidiaries to create or permit any Lien, other than a Permitted Lien, on any of the Guarantor’s assets to secure (i) any of the Guarantor’s Indebtedness, (ii) any of the Indebtedness of the Guarantor’s Material Subsidiaries or (iii) the Indebtedness of any other person, unless it contemporaneously creates or permits the Lien to secure equally and ratably the Guarantor’s obligations under this Guaranty or the Guarantor or such Material Subsidiary provides such other security for the 2021 Notes as is duly approved by the Trustee, at the direction of the Noteholders, in accordance with the Indenture.

 (h)       Provision of Financial Statements and Reports.  (i)  The Guarantor  will provide to the Trustee, in English or accompanied by a certified English translation thereof, (A) 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 Reporting GAAP, (B) 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 Reporting GAAP and (C) such other financial data as the Trustee may reasonably request.

(ii)        The Guarantor  will provide, together with each of the financial statements delivered pursuant to Sections 7(h)(i)(A) and (B), an Officer’s Certificate stating that a review of the activities of the Guarantor and the Issuer has been made during the period covered by such financial statements with a view to determining whether the Guarantor and the Issuer have kept, observed, performed and fulfilled their  covenants and agreements under this Guaranty and that no Default or Event of Default has occurred during such period or, if one or more have actually occurred, specifying all such events and what actions have been taken and will be taken with respect to such Default or Event of Default.

(iii)       The Guarantor shall, whether or not it is required to file reports with the SEC, file with the SEC and deliver to the Trustee (for redelivery to all Noteholders) all reports and other information as it would be required to file with the SEC under the Exchange Act if it were subject to those regulations; provided, however, that if the SEC does not permit the filing described in the first sentence of this Section 7(h)(iii), the Guarantor will provide annual and interim reports and other information to the Trustee within the same time periods that would be applicable if the Guarantor were required and permitted to file these reports with the SEC.

12

(iv)       Upon written request of any Holder or The Depository Trust Company (DTC), the reports and other information provided for in this paragraph (h) shall be delivered to DTC representing the Noteholders, at 55 Water Street, 25th Floor, New York, NY, 10041, Attention:  Proxy Department, or such other address as DTC may provide to the Trustee in writing.

SECTION 8.Amendments, Etc. No amendment or waiver of any provision of this Guaranty  and no consent to any departure by the Guarantor  therefrom shall in any event be effective unless the same shall be in writing and signed by the Trustee and the Guarantor, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given. For the avoidance of doubt, Article IX of the Indenture shall apply to an amendment to this Guaranty to determine whether the consent of Holders is required for an amendment and if so, the required percentage of Holders of the 2021 Notes required to approve the amendment. 

SECTION 9.Indemnity. The Guarantor agrees to fully indemnify the Trustee and any predecessor Trustee and their agents for, and to hold it harmless against, any and all loss, liability, damages, claims or expense arising out of or in connection with the performance of its duties under this Guaranty, including the costs and expenses of defending itself against any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder except to the extent that any such loss, liability or expense may be attributable to its negligence or bad faith.

SECTION 11.Survival.  Without prejudice to the survival of any of the other agreements of the Guarantor under this Guaranty or any of the other Transaction Documents, the agreements and obligations of the Guarantor contained in Section 2 (with respect to the payment of all other amounts owed under the Indenture), Section 9 and Section 14 shall survive the payment in full of the Guaranteed Obligations and all of the other amounts payable under this Guaranty, the termination of this Guaranty and/or the resignation or removal of the Trustee.

SECTION 12.No Waiver; Remedies. No failure on the part of the Trustee to exercise, and no delay in exercising, any right hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right hereunder preclude any other or further exercise thereof or the exercise of any other right.  The remedies herein provided are cumulative and not exclusive of any remedies provided by law.

SECTION 13.Continuing Agreement; Assignment of Rights Under the Indenture and the 2021 Notes. This Guaranty  is a continuing guaranty  and shall (a) remain in full force and effect until the later of (i) the repayment in full by the Issuer of all amounts due and owing under the Indenture with respect to the 2021 Notes and (ii) the repayment in full of all Guaranteed  Obligations and all other amounts payable under this Guaranty, (b) be binding upon the Guarantor, its successors and assigns and (c) inure to the benefit of and be enforceable by the Trustee, on behalf of Noteholders, and their successors, transferees and assigns.  Without limiting the generality of clause (c) of the immediately preceding sentence, any Noteholder may assign or otherwise transfer its rights and obligations under the Indenture (including, without limitation, the 2021 Note or 2021 Notes held by it) to any other person or entity, and such other person or entity shall thereupon become vested with all the benefits in respect thereof granted to such Noteholder herein or otherwise, in each case as and to the extent provided in the Indenture. The Guarantor  shall not have the right to assign its rights hereunder or any interest herein without the prior written consent of all of the Noteholders.

SECTION 14.Currency Rate Indemnity(a)  The Guarantor  shall (to the extent lawful) indemnify the Trustee and the Noteholders and keep them indemnified against:

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

            (ii)        any deficiency arising or resulting from any variation in rates of exchange between (a) the date as of which the local currency equivalent of the amounts due or contingently due under this Guaranty  or in respect of the 2021 Notes is calculated for the purposes of any bankruptcy, insolvency or liquidation of the Guarantor, and (b) the final date for ascertaining the amount of claims in such bankruptcy, insolvency or liquidation.  The amount of such deficiency shall be deemed not to be increased or reduced by any variation in rates of exchange occurring between the said final date and the date of any bankruptcy, insolvency or liquidation or any distribution of assets in connection therewith.

14

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

(c)      The above indemnities shall constitute separate and independent obligations of the Guarantor  from its obligations hereunder, will give rise to separate and independent causes of action, will apply irrespective of any indulgence granted from time to time and will continue in full force and effect notwithstanding any judgment or the filing of any proof or proofs in any bankruptcy, insolvency or liquidation of the Guarantor for a liquidated sum or sums in respect of amounts due under this Guaranty, or under the Indenture or the 2021 Notes or under any judgment or order.

SECTION 15.Governing Law; Jurisdiction; Waiver of Immunity, Etc. 

(a)This Guaranty shall be governed by, and construed in accordance with, the laws of the State of New York.

(b)The Guarantor  hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of any New York State court or federal court of the United States of sitting in New York City, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Guaranty  or any of the other Transaction Documents to which it is or is to be a party, or for recognition or enforcement of any judgment, and the Guarantor  hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in any such New York State court or, to the extent permitted by law, in such federal court.  The Guarantor agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.  Nothing in this Guaranty  or any other Transaction Document shall affect any right that any party may otherwise have to bring any action or proceeding against the Issuer or the Guarantor, as the case may be, relating to this Guaranty  or any other Transaction Document in the courts of any jurisdiction.

(c)The Guarantor  hereby irrevocably appoints and empowers the New York office of Petróleo Brasileiro S.A., located at 570 Lexington Avenue, 43rd Floor, New York, New York 10022 as its authorized agent (the “Process Agent”) to accept and acknowledge for and on its behalf and on behalf of its property service of any and all legal process, summons, notices and documents which may be served in any such suit, action or proceedings in any New York State court or United States federal  court sitting in the State of New York in the Borough of Manhattan and any appellate court from any thereof, which service may be made on such designee, appointee and agent in accordance with legal procedures prescribed for such courts.  The Guarantor will take any and all action necessary to continue such designation in full force and effect and to advise the Trustee of any change of address of such Process Agent and;  should such Process Agent become unavailable for this purpose for any reason, the Guarantor  will promptly and irrevocably designate a new Process Agent within New York, New York, which will agree to act as such, with the powers and for the purposes specified in this subsection (c).  The Guarantor  irrevocably consents and agrees to the service of  any and all legal process, summons, notices and documents out of any of the aforesaid courts in any such action, suit or proceeding by hand delivery, to it at its address set forth in Section 10  or to any other address of which it shall have given notice pursuant to Section 10 or to its Process Agent.  Service upon the Guarantor  or the Process Agent as provided for herein will, to the fullest extent permitted by law, constitute valid and effective personal service upon it and the failure of the Process Agent to give any notice of such service to the Guarantor  shall not impair or affect in any way the validity of such service or any judgment rendered in any action or proceeding based thereon.

15

(d)The Guarantor irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection that it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Guaranty or any of the other Transaction Documents to which it is or is to be a party in any New York State or federal court.  The Guarantor hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such suit, action or proceeding in any such court.

(e)THE GUARANTOR  HEREBY IRREVOCABLY WAIVES ALL RIGHT  TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS GUARANTY, ANY OF THE TRANSACTION DOCUMENTS, THE ADVANCES OR THE ACTIONS OF ANY NOTEHOLDER IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE OR ENFORCEMENT THEREOF.

(f)This Guaranty  and any other documents delivered pursuant hereto, and any actions taken hereunder, constitute commercial acts by the Guarantor.  The Guarantor irrevocably and unconditionally and to the fullest extent permitted by law, waives, and agrees not to plead or claim, any immunity from jurisdiction of any court or from any legal process (whether through service of  notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) for itself, the Issuer or any of their  property, assets or revenues wherever located with respect to its obligations, liabilities or any other matter under or arising out of or in connection with this Guaranty, any of the Transaction Documents or any document delivered pursuant hereto, in each case for the benefit of each assigns, it being intended that the foregoing waiver and agreement will be effective, irrevocable and not subject to withdrawal in any and all jurisdictions, and, without limiting the generality of the foregoing, agrees that the waivers set forth in this subsection (f) shall have the fullest scope permitted under the United States Foreign Sovereign Immunities Act of 1976 and are intended to be irrevocable for the purposes of such act.

SECTION 16.Execution in Counterparts. This Guaranty  and each amendment, waiver and consent with respect hereto may be executed in any number of counterparts and by different parties thereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement.  Delivery of an executed counterpart of a signature page to this Guaranty  by telecopier shall be effective as delivery of an original executed counterpart of this Guaranty.

(A)       the Guarantor  may merge, amalgamate or consolidate with or into, or convey, transfer, lease or otherwise dispose of all or substantially all of its properties, assets or revenues to a direct or indirect Subsidiary of the Guarantor  in cases when the Guarantor  is the surviving entity in such transaction and such transaction would not have a Material Adverse Effect on the Guarantor  and its Subsidiaries taken as a whole, it being understood that if the Guarantor  is not the surviving entity, the Guarantor  shall be required to comply with the requirements set forth in the previous paragraph; or

(B)       any direct or indirect Subsidiary of the Guarantor  may merge or consolidate with or into, or convey, transfer, lease or otherwise dispose of assets to, any person (other than the Guarantor or any of its Subsidiaries or Affiliates) in cases when such transaction would not have a Material Adverse Effect on the Guarantor  and its Subsidiaries taken as a whole; or

(C)       any direct or indirect Subsidiary of the Guarantor  may merge or consolidate with or into, or convey, transfer, lease or otherwise dispose of assets to, any direct or indirect Subsidiary of the Guarantor; or

(c)The Guarantor  hereby irrevocably appoints and empowers the New York office of Petróleo Brasileiro S.A., located at 570 Lexington Avenue, 43rd Floor, New York, New York 10022 as its authorized agent (the “Process Agent”) to accept and acknowledge for and on its behalf and on behalf of its property service of any and all legal process, summons, notices and documents which may be served in any such suit, action or proceedings in any New York State court or United States federal  court sitting in the State of New York in the Borough of Manhattan and any appellate court from any thereof, which service may be made on such designee, appointee and agent in accordance with legal procedures prescribed for such courts.  The Guarantor  will take any and all action necessary to continue such designation in full force and effect and to advise the Trustee of any change of address of such Process Agent and;  should such Process Agent become unavailable for this purpose for any reason, the Guarantor  will promptly and irrevocably designate a new Process Agent within New York, New York, which will agree

15

to act as such, with the powers and for the purposes specified in this subsection (c).  The Guarantor  irrevocably consents and agrees to the service of  any and all legal process, summons, notices and documents out of any of the aforesaid courts in any such action, suit or proceeding by hand delivery, to it at its address set forth in Section 10  or to any other address of which it shall have given notice pursuant to Section 10 or to its Process Agent.  Service upon the Guarantor  or the Process Agent as provided for herein will, to the fullest extent permitted by law, constitute valid and effective personal service upon it and the failure of the Process Agent to give any notice of such service to the Guarantor  shall not impair or affect in any way the validity of such service or any judgment rendered in any action or proceeding based thereon.

(d)The Guarantor irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection that it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Guaranty or any of the other Transaction Documents to which it is or is to be a party in any New York State or federal court.  The Guarantor hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such suit, action or proceeding in any such court.

(f)This Guaranty  and any other documents delivered pursuant hereto, and any actions taken hereunder, constitute commercial acts by the Guarantor.  The Guarantor  irrevocably and unconditionally and to the fullest extent permitted by law, waives, and agrees not to plead or claim, any immunity from jurisdiction of any court or from any legal process (whether through service of  notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) for itself, the Issuer or any of their  property, assets or revenues wherever located with respect to its obligations, liabilities or any other matter under or arising out of or in connection with this Guaranty, any of the Transaction Documents or any document delivered pursuant hereto, in each case for the benefit of each assigns, it being intended that the foregoing waiver and agreement will be effective, irrevocable and not subject to withdrawal in any and all jurisdictions, and, without limiting the generality of the foregoing, agrees that the waivers set forth in this subsection (f) shall have the fullest scope permitted under the United States Foreign Sovereign Immunities Act of 1976 and are intended to be irrevocable for the purposes of such act.

SECTION 16.Execution in Counterparts.  This Guaranty  and each amendment, waiver and consent with respect hereto may be executed in any number of counterparts and by different parties thereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement.  Delivery of an executed counterpart of a signature page to this Guaranty  by telecopier shall be effective as delivery of an original executed counterpart of this Guaranty.

Rio de Janeiro-RJ-Brazil

Gentlemen:

Pursuant to your request, we have conducted a reserves audit of the net proved crude oil, condensate, and natural gas reserves, as of December 31, 2010, of certain properties owned by Petróleo Brasileiro S.A. (Petrobras). The properties are located in Brazil and offshore from Brazil. Petrobras has represented that these properties account for 94.9 percent on a net equivalent barrel basis of Petrobras’ net proved reserves, as of December 31, 2010, and that the net proved reserves estimates have been prepared in accordance with the reserves definitions of Rules 4–10(a) (1)–(32) of Regulation S–X of the Securities and Exchange Commission (SEC) of the United States. We have reviewed information provided to us by Petrobras that it represents to be Petrobras’ estimates of the net reserves, as of December 31, 2010, for the same properties as those which we evaluated. The results of our reserves audit, completed on February 22, 2011, are compared to Petrobras’ estimates of reserves and comments on such comparison are presented herein.

Reserves included herein are expressed as net reserves as represented by Petrobras. Gross reserves are defined as the total estimated petroleum to be produced from these properties after December 31, 2010. Net reserves are defined as that portion of the gross reserves attributable to the interests owned by Petrobras after deducting all interests owned by others.

Estimates of oil, condensate, and natural gas should be regarded only as estimates that may change as further production history and additional information become available. Not only are such reserves estimates based on that information which is currently available, but such estimates are also subject to the uncertainties inherent in the application of judgmental factors in interpreting such information.

2

Data used in this audit were obtained from reviews with Petrobras personnel, Petrobras files, from records on file with the appropriate regulatory agencies, and from public sources. In the preparation of this report we have relied, without independent verification, upon such information furnished by Petrobras with respect to property interests, production from such properties, current costs of operation and development, current prices for production, agreements relating to current and future operations and sale of production, and various other information and data that were accepted as represented. A field examination of the properties was not considered necessary for the purposes of this report.

Methodology and Procedures

Estimates of reserves were prepared by the use of appropriate geologic, petroleum engineering, and evaluation principals and techniques that are in accordance with practices generally recognized by the petroleum industry as presented in the publication of the Society of Petroleum Engineers entitled “Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information (Revision as of February 19, 2007).” The method or combination of methods used in the analysis of each reservoir was tempered by experience with similar reservoirs, stage of development, quality and completeness of basic data, and production history.

When applicable, the volumetric method was used to estimate the original oil in place (OOIP) and the original gas in place (OGIP). Structure and isopach maps were constructed to estimate reservoir volume. Electrical logs, radioactivity logs, core analyses, and other available data were used to prepare these maps as well as to estimate representative values for porosity and water saturation. When adequate data were available and when circumstances justified, material balance and other engineering methods were used to estimate OOIP or OGIP.

Estimates of ultimate recovery were obtained after applying recovery factors to OOIP or OGIP. These recovery factors were based on consideration of the type of energy inherent in the reservoirs, analyses of the petroleum, the structural positions of the properties, and the production histories. When applicable, material balance and other engineering methods were used to estimate recovery factors. An analysis of reservoir performance, including production rate, reservoir pressure, and gas-oil ratio behavior, was used in the estimation of reserves.

For depletion-type reservoirs or those whose performance disclosed a reliable decline in producing-rate trends or other diagnostic characteristics, reserves were estimated by the application of appropriate decline curves or other performance relationships. In the analyses of production‑decline curves, reserves were estimated only to the limits of economic production or to the limit of the production licenses as appropriate.

Definition of Reserves

Petroleum reserves estimated by Petrobras included in this report are classified as proved. Only proved reserves have been evaluated for this report. Reserves classifications used by Petrobras in this report are in accordance with the reserves definitions of Rules 4–10(a) (1)–(32) of Regulation S–X of the SEC. Reserves are judged to be economically producible in future years from known reservoirs under existing economic and operating conditions and assuming continuation of current regulatory practices using conventional production methods and equipment. In the analyses of production-decline curves, reserves were estimated only to the limit of economic rates of production under existing economic and operating conditions using prices and costs consistent with the effective date of this report, including consideration of changes in existing prices provided only by contractual arrangements but not including escalations based upon future conditions. The petroleum reserves are classified as follows:

Proved oil and gas reserves – Proved oil and gas reserves are those quantities of oil and gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible—from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations—prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. The project to extract the hydrocarbons must have commenced or the operator must be reasonably certain that it will commence the project within a reasonable time.

(i) The area of the reservoir considered as proved includes:

(A) The area identified by drilling and limited by fluid contacts, if any, and (B) Adjacent undrilled portions of the reservoir that can, with reasonable certainty, be judged to be continuous with it and to contain economically producible oil or gas on the basis of available geoscience and engineering data.

(ii) In the absence of data on fluid contacts, proved quantities in a reservoir are limited by the lowest known hydrocarbons (LKH) as seen in a well penetration unless geoscience, engineering, or performance data and reliable technology establishes a lower contact with reasonable certainty.

4

(iii) Where direct observation from well penetrations has defined a highest known oil (HKO) elevation and the potential exists for an associated gas cap, proved oil reserves may be assigned in the structurally higher portions of the reservoir only if geoscience, engineering, or performance data and reliable technology establish the higher contact with reasonable certainty.

(iv) Reserves which can be produced economically through application of improved recovery techniques (including, but not limited to, fluid injection) are included in the proved classification when:

(A) Successful testing by a pilot project in an area of the reservoir with properties no more favorable than in the reservoir as a whole, the operation of an installed program in the reservoir or an analogous reservoir, or other evidence using reliable technology establishes the reasonable certainty of the engineering analysis on which the project or program was based; and (B) The project has been approved for development by all necessary parties and entities, including governmental entities.

(v) Existing economic conditions include prices and costs at which economic producibility from a reservoir is to be determined. The price shall be the average price during the 12‑month period prior to the ending date of the period covered by the report, determined as an unweighted arithmetic average of the first-day-of-the-month price for each month within such period, unless prices are defined by contractual arrangements, excluding escalations based upon future conditions.

Developed oil and gas reserves – Developed oil and gas reserves are reserves of any category that can be expected to be recovered:

(i) Through existing wells with existing equipment and operating methods or in which the cost of the required equipment is relatively minor compared to the cost of a new well; and

(ii) Through installed extraction equipment and infrastructure operational at the time of the reserves estimate if the extraction is by means not involving a well.

5

Undeveloped oil and gas reserves – Undeveloped oil and gas reserves are reserves of any category that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion.

(i) Reserves on undrilled acreage shall be limited to those directly offsetting development spacing areas that are reasonably certain of production when drilled, unless evidence using reliable technology exists that establishes reasonable certainty of economic producibility at greater distances.

(ii) Undrilled locations can be classified as having undeveloped reserves only if a development plan has been adopted indicating that they are scheduled to be drilled within five years, unless the specific circumstances justify a longer time.

(iii) Under no circumstances shall estimates for undeveloped reserves be attributable to any acreage for which an application of fluid injection or other improved recovery technique is contemplated, unless such techniques have been proved effective by actual projects in the same reservoir or an analogous reservoir, as defined in section 210.4–10 (a) Definitions, or by other evidence using reliable technology establishing reasonable certainty.

Primary Economic Assumptions

The following economic assumptions were used for estimating existing and future prices and costs:

Oil and Condensate Prices

Petrobras has represented that the oil and condensate prices were based on a 12-month average price, calculated as the unweighted arithmetic average of the first-day-of-the-month price for each month within the 12-month period prior to the end of the reporting period, unless prices are defined by contractual arrangements. Petrobras supplied differentials by field to a Brent reference price of $79.22 per barrel and the prices were held constant thereafter. The volume-weighted average price attributable to estimated proved reserves was $67.83 per barrel. These prices were not escalated for inflation.

6

Natural Gas Prices

Petrobras has represented that the natural gas prices were based on a 12-month average price, calculated as the unweighted arithmetic average of the first-day-of-the-month price for each month within the 12-month period prior to the end of the reporting period, unless prices are defined by contractual arrangements. The 12-month average adjusted product price was U.S.$7.66 per thousand cubic feet (Mcf) based on a 12‑month average internal product transfer price of U.S.$7.45 per Mcf provided by Petrobras. The internal product transfer price is the agreed price of gas between Petrobras E&P (upstream division) and Petrobras Gas & Energy (downstream division). The volume-weighted average price attributable to estimated proved reserves was $7.66 per Mcf. These prices were not escalated for inflation.

Operating Expenses and Capital Costs

Operating expenses and capital costs, based on information provided by Petrobras, were used in estimating future costs required to operate the properties. In certain cases, future costs, either higher or lower than existing costs, may have been used because of anticipated changes in operating conditions. These costs were not escalated for inflation.

While the oil and gas industry may be subject to regulatory changes from time to time that could affect an industry participant’s ability to recover its oil and gas reserves, we are not aware of any such governmental actions which would restrict the recovery of the December 31, 2010, estimated oil and gas volumes. The reserves estimated in this report can be produced under current regulatory guidelines.

7

Petrobras has represented that its estimated net proved reserves attributable to the reviewed properties are based on the definitions of proved reserves of the SEC. Petrobras represents that its estimates of the net proved reserves attributable to these properties which represent 97.9 percent of Petrobras’ reserves on a net equivalent basis are as follows, expressed in millions of barrels (MMbbl), billions of cubic feet (Bcf), and millions of barrels of oil equivalent (MMboe):

	Estimated by Petrobras Net Proved Reserves as of December 31, 2010
	Oil and Condensate (MMbbl)	Natural Gas (Bcf)	Oil Equivalent (MMboe)
Properties reviewed by DeGolyer and MacNaughton
Brazil
Proved Developed	6,532.7	6,453.0	7,608.2
Proved Undeveloped	3,334.7	3,466.8	3,912.5
Total Proved Brazil	9,867.4	9,919.8	11,520.7
Note: Gas is converted to oil equivalent using a factor of 6,000 cubic feet of gas per 1 barrel of oil equivalent.

In our opinion, the information relating to estimated proved reserves of oil, condensate, natural gas liquids, and gas contained in this report has been prepared in accordance with Paragraphs 932-235-50-4, 932-235-50-6, 932-235-50-7, and 932-235-50-9 of the Accounting Standards Update 932-235-50, Extractive Industries – Oil and Gas (Topic 932): Oil and Gas Reserve Estimation and Disclosures (January 2010) of the Financial Accounting Standards Board and Rules 4–10(a) (1)–(32) of Regulation S–X and Rules 302(b), 1201, 1202(a) (1), (2), (3), (4), (8), and 1203(a) of Regulation S–K of the Securities and Exchange Commission.

8

In comparing the detailed net proved reserves estimates prepared by us and by Petrobras, we have found differences, both positive and negative resulting in an aggregate difference of 3.05 percent when compared on the basis of net equivalent barrels. It is our opinion that the net proved reserves estimates prepared by Petrobras on the properties reviewed by us and referred to above, when compared on the basis of net equivalent barrels, in aggregate, do not differ materially from those prepared by us. This opinion is based on a detailed and independent reserves evaluation of over 97.9 percent of Petrobras’ net proved reserves in Brazil conducted in accordance with the methodology and procedures set forth above.

DeGolyer and MacNaughton is an independent petroleum engineering consulting firm that has been providing petroleum consulting services throughout the world for over 70 years. DeGolyer and MacNaughton does not have any financial interest, including stock ownership, in Petrobras. Our fees were not contingent on the results of our evaluation. This letter report has been prepared at the request of Petrobras. DeGolyer and MacNaughton has used all assumptions, data, procedures, and methods that it considers necessary and appropriate to prepare this report.

Gentlemen:

Pursuant to your request, we have conducted a reserves evaluation of the net proved crude oil, condensate, and natural gas reserves, as of December 31, 2010, of certain selected properties in North America and South America (outside of Brazil)  owned by Petróleo Brasileiro S.A. (Petrobras). Petrobras has represented that these properties account for 91 percent on a net equivalent barrel basis of Petrobras’ net proved reserves in operated fields outside of Brazil as of December 31, 2010. The net proved reserves estimates prepared by us have been prepared in accordance with the reserves definitions of Rules 4–10(a) (1)–(32) of Regulation S–X of the Securities and Exchange Commission (SEC) of the United States. The results of our reserves audit, completed on February 22, 2011, are presented herein.

Reserves included herein are expressed as net reserves. Gross reserves are defined as the total estimated petroleum to be produced from these properties after December 31, 2010. Net reserves are defined as that portion of the gross reserves attributable to the interests owned by Petrobras after deducting all interests owned by others.

Estimates of oil, condensate, and natural gas should be regarded only as estimates that may change as further production history and additional information become available. Not only are such reserves estimates based on that information which is currently available, but such estimates are also subject to the uncertainties inherent in the application of judgmental factors in interpreting such information.

11

Data used in this evaluation were obtained from reviews with Petrobras personnel, Petrobras files, from records on file with the appropriate regulatory agencies, and from public sources. Additionally, this information includes data supplied by Petroleum Information/Dwights LLC; Copyright 2010 Petroleum Information/Dwights LLC. In the preparation of this report we have relied, without independent verification, upon such information furnished by Petrobras with respect to property interests, production from such properties, current costs of operation and development, current prices for production, agreements relating to current and future operations and sale of production, and various other information and data that were accepted as represented. A field examination of the properties was not considered necessary for the purposes of this report.

Methodology and Procedures

Estimates of reserves were prepared by the use of appropriate geologic, petroleum engineering, and evaluation principals and techniques that are in accordance with practices generally recognized by the petroleum industry as presented in the publication of the Society of Petroleum Engineers entitled “Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information (Revision as of February 19, 2007).” The method or combination of methods used in the analysis of each reservoir was tempered by experience with similar reservoirs, stage of development, quality and completeness of basic data, and production history.

When applicable, the volumetric method was used to estimate the original oil in place (OOIP) and the original gas in place (OGIP). Structure and isopach maps were constructed to estimate reservoir volume. Electrical logs, radioactivity logs, core analyses, and other available data were used to prepare these maps as well as to estimate representative values for porosity and water saturation. When adequate data were available and when circumstances justified, material balance and other engineering methods were used to estimate OOIP or OGIP.

Estimates of ultimate recovery were obtained after applying recovery factors to OOIP or OGIP. These recovery factors were based on consideration of the type of energy inherent in the reservoirs, analyses of the petroleum, the structural positions of the properties, and the production histories. When applicable, material balance and other engineering methods were used to estimate recovery factors. An analysis of reservoir performance, including production rate, reservoir pressure, and gas-oil ratio behavior, was used in the estimation of reserves.

For depletion-type reservoirs or those whose performance disclosed a reliable decline in producing-rate trends or other diagnostic characteristics, reserves were estimated by the application of appropriate decline curves or other performance relationships. In the analyses of production‑decline curves, reserves were estimated only to the limits of economic production or to the limit of the production licenses as appropriate.

Definition of Reserves

Petroleum reserves estimated by us included in this report are classified as proved. Only proved reserves have been evaluated for this report. Reserves classifications used by us in this report are in accordance with the reserves definitions of Rules 4–10(a) (1)–(32) of Regulation S–X of the SEC. Reserves are judged to be economically producible in future years from known reservoirs under existing economic and operating conditions and assuming continuation of current regulatory practices using conventional production methods and equipment. In the analyses of production-decline curves, reserves were estimated only to the limit of economic rates of production under existing economic and operating conditions using prices and costs consistent with the effective date of this report, including consideration of changes in existing prices provided only by contractual arrangements but not including escalations based upon future conditions. The petroleum reserves are classified as follows:

Proved oil and gas reserves – Proved oil and gas reserves are those quantities of oil and gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible—from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations—prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. The project to extract the hydrocarbons must have commenced or the operator must be reasonably certain that it will commence the project within a reasonable time.

(i) The area of the reservoir considered as proved includes:

(A) The area identified by drilling and limited by fluid contacts, if any, and (B) Adjacent undrilled portions of the reservoir that can, with reasonable certainty, be judged to be continuous with it and to contain economically producible oil or gas on the basis of available geoscience and engineering data.

(ii) In the absence of data on fluid contacts, proved quantities in a reservoir are limited by the lowest known hydrocarbons (LKH) as seen in a well penetration unless geoscience, engineering, or performance data and reliable technology establishes a lower contact with reasonable certainty.

13

(iii) Where direct observation from well penetrations has defined a highest known oil (HKO) elevation and the potential exists for an associated gas cap, proved oil reserves may be assigned in the structurally higher portions of the reservoir only if geoscience, engineering, or performance data and reliable technology establish the higher contact with reasonable certainty.

(iv) Reserves which can be produced economically through application of improved recovery techniques (including, but not limited to, fluid injection) are included in the proved classification when:

(A) Successful testing by a pilot project in an area of the reservoir with properties no more favorable than in the reservoir as a whole, the operation of an installed program in the reservoir or an analogous reservoir, or other evidence using reliable technology establishes the reasonable certainty of the engineering analysis on which the project or program was based; and (B) The project has been approved for development by all necessary parties and entities, including governmental entities.

(v) Existing economic conditions include prices and costs at which economic producibility from a reservoir is to be determined. The price shall be the average price during the 12‑month period prior to the ending date of the period covered by the report, determined as an unweighted arithmetic average of the first-day-of-the-month price for each month within such period, unless prices are defined by contractual arrangements, excluding escalations based upon future conditions.

Developed oil and gas reserves – Developed oil and gas reserves are reserves of any category that can be expected to be recovered:

(i) Through existing wells with existing equipment and operating methods or in which the cost of the required equipment is relatively minor compared to the cost of a new well; and

(ii) Through installed extraction equipment and infrastructure operational at the time of the reserves estimate if the extraction is by means not involving a well.

14

Undeveloped oil and gas reserves – Undeveloped oil and gas reserves are reserves of any category that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion.

(i) Reserves on undrilled acreage shall be limited to those directly offsetting development spacing areas that are reasonably certain of production when drilled, unless evidence using reliable technology exists that establishes reasonable certainty of economic producibility at greater distances.

(ii) Undrilled locations can be classified as having undeveloped reserves only if a development plan has been adopted indicating that they are scheduled to be drilled within five years, unless the specific circumstances justify a longer time.

(iii) Under no circumstances shall estimates for undeveloped reserves be attributable to any acreage for which an application of fluid injection or other improved recovery technique is contemplated, unless such techniques have been proved effective by actual projects in the same reservoir or an analogous reservoir, as defined in section 210.4–10 (a) Definitions, or by other evidence using reliable technology establishing reasonable certainty.

Primary Economic Assumptions

The following economic assumptions were used for estimating existing and future prices and costs:

Oil and Condensate Prices

Petrobras has represented that the oil and condensate prices were based on a 12-month average price, calculated as the unweighted arithmetic average of the first-day-of-the-month price for each month within the 12-month period prior to the end of the reporting period, unless prices are defined by contractual arrangements. The 12-month average adjusted product price in South America was U.S.$67.21 per barrel and the 12-month average adjusted product price in North America was U.S.$76.99 per barrel. Petrobras supplied differentials by field to a West Texas Intermediate reference price of $76.99 per barrel and the prices were held constant thereafter. The volume-weighted average price attributable to estimated proved reserves was $67.83 per barrel. These prices were not escalated for inflation.

15

Natural Gas Prices

Petrobras has represented that the natural gas prices were based on a 12-month average price, calculated as the unweighted arithmetic average of the first-day-of-the-month price for each month within the 12-month period prior to the end of the reporting period, unless prices are defined by contractual arrangements. The 12-month average adjusted product price in South America was U.S.$2.58 per thousand cubic feet based on the 12-month weighted average of contract prices provided by Petrobras. The 12‑month average adjusted product price in North America was U.S.$4.78 per thousand cubic feet, based on a 12-month average Henry Hub reference price of U.S.$ 4.78 per thousand cubic feet. The volume-weighted average price attributable to estimated proved reserves was $2.85 per Mcf. These prices were not escalated for inflation.

Operating Expenses and Capital Costs

Operating expenses and capital costs, based on information provided by Petrobras, were used in estimating future costs required to operate the properties. In certain cases, future costs, either higher or lower than existing costs, may have been used because of anticipated changes in operating conditions. These costs were not escalated for inflation.

While the oil and gas industry may be subject to regulatory changes from time to time that could affect an industry participant’s ability to recover its oil and gas reserves, we are not aware of any such governmental actions which would restrict the recovery of the December 31, 2010, estimated oil and gas volumes. The reserves estimated in this report can be produced under current regulatory guidelines.

16

Our estimates of Petrobras’ net proved reserves attributable to the reviewed properties are based on the definitions of proved reserves of the SEC and are as follows, expressed in millions of barrels (MMbbl), millions of cubic feet (MMcf), and millions of barrels of oil equivalent (MMboe):

	Estimated by DeGolyer and MacNaughton Net Proved Reserves as of December 31, 2010
	Oil and Condensate (MMbbl)	Natural Gas (MMcf)	Oil Equivalent (MMboe)
North America
Proved Developed	4.966	26,662	9.410
Proved Undeveloped	5.158	19,115	8.344
Total Proved North America	10.124	45,777	17.754
South America (outside of Brazil)
Proved Developed	84.579	424,248	155.287
Proved Undeveloped	65.510	411,909	134.162
Total Proved South America (outside of Brazil)	150.089	836,157	289.449
Total Proved	160.213	881,934	307.203
Notes: 1. Gas is converted to oil equivalent using a factor of 6,000 cubic feet of gas per 1 barrel of oil equivalent. 2. Of the total 307.203 MMboe net proved reserves, 300.665 MMboe is directly related to Petrobras’ operated fields. 3. Reserves in Argentina include only Petrobras Argentina S.A.’s interest.

In our opinion, the information relating to estimated proved reserves of oil, condensate, natural gas liquids, and gas contained in this report has been prepared in accordance with Paragraphs 932-235-50-4, 932-235-50-6, 932-235-50-7, and 932-235-50-9 of the Accounting Standards Update 932-235-50, Extractive Industries – Oil and Gas (Topic 932): Oil and Gas Reserve Estimation and Disclosures (January 2010) of the Financial Accounting Standards Board and Rules 4–10(a) (1)–(32) of Regulation S–X and Rules 302(b), 1201, 1202(a) (1), (2), (3), (4), (8), and 1203(a) of Regulation S–K of the Securities and Exchange Commission.

15.1) Pension plans in Brazil - Defined benefit and variable contribution

a) Petros Plan - Fundação Petrobras de Seguridade Social

The Fundação Petrobras de Seguridade Social (Petros) was established by Petrobras as a private, legally separate nonprofit pension entity with administrative and financial autonomy.

The Petros plan is a contributory defined-benefit pension plan introduced by Petrobras in July of 1970, to supplement the social security pension benefits of employees of Petrobras and its Brazilian subsidiaries and affiliated companies. The Petros Plan is now closed to new employees of the Petrobras system since September 2002.

Additionally, Petros is funded by income resulting from the investment of these contributions. The Company's funding policy is to contribute to the plan annually the amount determined by actuarial calculations. In the calendar 2010 year, benefits paid totaled US$1,054 (US$911 in 2009).

The Company's liability related to future benefits to plan participants is calculated on an annual basis by an independent actuary, based on the Projected Unit Credit method. The assets that guarantee the pension plan are presented as a reduction to the net actuarial liabilities.

The actuarial gains and losses generated by the differences between the values of the obligation and assets determined based on projections and the actual figures are respectively included or excluded from the calculation of the net actuarial liability and recorded as "Postretirement benefit reserves adjustments net of tax - pension cost", in shareholders' equity. Actuarial gains and losses are amortized during the average remaining service period of the active employees of approximately 6.5 years at December 31, 2009, in accordance with the procedure established by Codification Topic 715.

The relation between contributions by the sponsors and participants of the Petros Plan, considering only those attributable to the Company and subsidiaries in the 2010 and 2009 financial years was 1.00 to 1.00. The Company's best estimate of contributions expected to be paid in 2011 respective to the pension plan approximates US$540, with total pension benefit payments in 2011 expected to be US$1,695.

According to Constitutional Amendment No. 20 of 1998, the computation of any deficit in the defined-benefit plan in accordance with the actuarial method of the current plan (which differs from the method defined in Codification Topic 715), must be equally shared between the sponsor and the participants, by an adjustment to the normal contributions.

Petrobras and its subsidiaries sponsoring the Petros plan, trade unions and Petros executed a Financial Commitment Agreement on October 23, 2008, after legal homologation on August 25, 2008, to cover commitments with pension plans, which will be paid in semi-annually installments with interest of 6% p.a. on the debtor balance updated by the IPCA, for the next 20 years, as previously agreed during the renegotiation. At December 31, 2010, the balance of the obligation of Petrobras and subsidiaries referring to the Financial Commitment Agreement was US$2,874, of which US$175 matures in 2011, which are recognized in these consolidated financial statements.

The Company's obligation, through the Financial Commitment Agreement, presents a counterpart to the concessions made by the members/beneficiaries of the Petros Plan in the amendment of the plan's regulations, in relation to the benefits, and in the closing of existing litigations.

At December 31, 2010, Petrobras had long-term National Treasury Notes in the amount of US$2,939 (US2,363 at December 31, 2009), acquired to balance liabilities with Petros, which will be held in the Company's portfolio and used as a guarantee for the Financial Commitment Agreement.

Petrobras has aggregated information for all defined benefit pension plans. The domestic benefit plans of Petrobras, BR Distribuidora, Petroquisa, and REFAP contain similar assumptions and the benefit obligation related to Petrobras Argentina, the international plan, is not significant to the total obligation and thus has also been aggregated. All Petrobras group pension plans have accumulated benefit obligation in excess of plan assets.

The determination of the expense and liability relating to the Company's pension plan involves the use of judgment in the determination of actuarial assumptions. These include estimates of future mortality, withdrawal, changes in compensation and discount rate to reflect the time value of money as well as the rate of return on plan assets. These assumptions are reviewed at least annually and may differ materially from actual results due to changing market and economic conditions, regulatory events, judicial rulings, higher or lower withdrawal rates or longer or shorter life spans of participants.

According to the requirements of Codification Topic 715, and subsequent interpretations, the discount rate should be based on current prices for settling the pension obligation. Applying the precepts of Codification Topic 715, in historically inflationary environments such as Brazil creates certain issues as the ability for a company to settle a pension obligation at a future point in time may not exist as long-term financial instruments of suitable grade may not exist locally as they do in the United States.

Although the Brazilian market has been demonstrating signs of stabilization under the present economic model, as reflected in market interest rates, it is not yet prudent to conclude that market interest rates will be stable.

b) Petros Plan 2 - Fundação Petrobras de Seguridade Social

As from July 01, 2007, the Company implemented the new supplementary pension plan, a Variable Contribution (CV) or mixed plan, called Petros Plan 2, for employees with no supplementary pension plan.

Petrobras and the other sponsors fully assumed the contributions corresponding to the period in which the participants had no plan. This past service shall consider the period as from August 2002, or from the date of hiring, until August 29, 2007. The plan will continue to admit new subscribers after this date but no longer including any payment for the period relating to past service.

A portion of this plan with defined benefits characteristics refers to the risk coverage for disability and death, a guarantee of a minimum benefit and a lifetime income, and the related actuarial commitments are recorded according to the projected credit unit method. The portion of the plan with defined contribution characteristics, earmarked for forming a reserve for programmed retirement, was recognized in the results for the year as the contributions are made. In fiscal year 2010, the contribution of Petrobras and subsidiaries to the defined contribution portion of this plan was US$231.

The disbursements related to the cost of past service will be made on a monthly basis over the same number of months during which the participant had no plan and, therefore, should cover the part related to the participants and the sponsors.

The actuarial evaluation in 2009 of Fundação Petros, to attend the rules for Supplementary Pensions, showed evidence of a lower level of loss from risk events in the year, and it also observed that the balance of the collective risk fund presented an amount sufficient to cover the estimated benefits for 2010. Accordingly, the Foundation followed the actuary's suggestion that the risk contributions were redirected to the member's account in the plan during the first semester of 2010.

15.2) Pension plans abroad - Defined benefit

The main defined benefit plans offered by the subsidiaries of Petrobras Internacional Braspetro B.V. (PIB BV), are as follows:

• Petrobras Energía S.A.

a) "Termination Indemnity" Plan

This is a benefit plan in which employees who meet certain targets are eligible on retirement to receive one month's salary for each year they have worked in the company, according to a decreasing scale, according to the number of the years the plan has existed.

b) "Compensating Fund"

This benefit is available to all Pesa employees who have joined the defined contribution plans in force in the past and who joined the company prior to May 31, 1995 and have accumulated the required time of service.

• Nansei Sekiyu S.A.

The Nansei Sekiyu Refinery offers its employees a programmed supplementary retirement benefits plan, a defined benefit plan, where the members in order to become eligible for the benefit need to be at least 50 years old and have 20 years service in the company. Contributions are made only by the sponsor.

15.3) Other defined contribution plans

The subsidiaries Transpetro and some subsidiaries of Petrobras sponsor defined contribution retirement plans for their employees

15.4) Plan assets

Investment Policies and Strategies

The Corporation's investment strategy for benefit plan assets reflects a long-term view, a careful assessment of the risks inherent in various asset classes and diversification to reduce the risk of the portfolio. The plan asset portfolio should follow the policies established by the Central Bank of Brazil. The fixed income funds are largely invested in corporate and government debt securities. The target asset allocation for the period between 2011-2015 is (25%-70%) fixed income, (15%-50%) variable income, (1,5%- 8%) real estate, (0%-15%) loans to participants of the plan and (2,5% - 15%) other investments.

Fair Value Measurements at December 31, 2010 (US$ millions)
Asset Category	Total Fair Value	Level 1	Level 2	Level 3	Allocation %
Fixed Income	14,810	9,483	5,327	-	54%
Corporate bonds	5,254	-	5,254	-	19%
Government bonds - Brazil	9,483	9,483	-	-	35%
Others	73	-	73	-	-
Variable income	10,974	6,280	1,319	3,375	40%
Brazilian Equity Securities	6,280	6,280	-	-	23%
Equity funds	4,670	-	1,296	3,374	17%
Other Investments	24	-	23	1	-
Real estate	877	-	-	877	3%
	26,661	15,763	6,646	4,252	97%
Loans	679				3%
Total	27,340				100%

Loans are valued at cost, which approximates fair value. Fair values of fixed income assets include government bonds and the fair value is based on observable quoted prices that are traded on active exchanges (Level 1).

Fair values of Brazilian equity securities categorized in Level 1 are primarily based on quoted market prices. The equity securities include investments in the Company's common stock and preferred shares in the amount of US$1,042 and US$790, respectively, at December 31, 2010.

Corporate debt securities are estimated using observable inputs of comparable market transactions. Other equity funds have their fair value estimated using the variation of quoted prices in active markets for identical assets adjusted for transaction costs of the funds and are treated as a Level 2.

The fair value of equity funds Level 3 are calculated using the discounted cash flow. The effect of fair-value measurements using significant unobservable inputs on changes in Level 3 plan assets for the period is:

	US$ million
	Private equity funds	Other Investiments	Real estate	Total
Total at December 31,2009	2,403	10	505	2,918
Profitability of Plan Assets:	841	-	142	983
Purchases, Sales and Settlements	8	(9)	202	201
Gain on translation	122	-	28	150
Total at December 31, 2010	3,374	1	877	4,252

The investment portfolio of the Petros Plan and Petros 2 at December 31, 2010 was composed of: 54% of fixed income, with expected profitability of 6.2% p.a.; 40% of variable income, with expected profitability of 8% p.a.; and 6% of other investments (transactions with members, real estate and infrastructure projects), which resulted in an average interest rate of 6.78% p.a.

15.5) Health care benefits - "Assistência Multidisciplinar de Saúde" (AMS)

Petrobras and its Brazilian subsidiaries maintain a health care benefit plan (AMS), which offers defined benefits and covers all employees (active and inactive) together with their dependents. The plan is managed by the Company, with the employees contributing fixed amounts to cover principal risks and a portion of the costs relating to other types of coverage in accordance with participation tables defined by certain parameters including salary levels, besides the Medicine Benefit, which provides special terms on the acquisition of certain medicines from participating drugstores, located throughout Brazil.

The Company's commitment related to future benefits to plan participants is calculated on an annual basis by an independent actuary, based on the Projected Unit Credit method. The health care plan is not funded or otherwise collateralized by assets. Instead, the Company makes benefit payments based on costs incurred by plan participants.

15.5) Health care benefits - "Assistência Multidisciplinar de Saúde" (AMS)

For measurement purposes, a 10% annual rate of increase in the per capita cost of covered health care benefits was assumed upon adoption of Codification Topic 715. The annual rate was assumed to decrease to 4.5% from 2007 to 2036.

Assumed health care cost trend rates have a significant effect on the amounts reported for the postretirement health care plan. A one-percentage-point change in assumed health care cost trend rates would have the following effects:

	One percentage	One percentage
	point-increase	point-decrease
Effect on total of services and interest cost component	147	(119)
Effect on postretirement benefit obligation	1,210	(991)

d) Assumptions

The main assumptions adopted in 2010 and 2009 for the actuarial calculation are summarized as follows:

	2010	2009
Discount rate	Inflation 5.3% to 4.3% p.a. (1) + interest 5.91% p.a.(2)	Inflation 4.5% to 4% p.a.(1) + interest: 6.57% p.a.(2)
Growth rate for salaries	Inflation 5.3% to 4.3% p.a. (1) + 2.220% p.a	Inflation 4.5% to 4% p.a.(1) + 2.295% p.a
Expected return rate from the pension plan assets	Inflation 5.3% p.a.(1) + interest: 6.78% p.a.	Inflation 4.5% p.a.(1)+ interest:6.74.% p.a.
Turnover rate of the health plans	0.660% p.a. (3)	0.768% p.a.(3)
Turnover rate of the pension plans	Null	Null
Rate for hospital medical costs	7.89% to 4.3% p.a. (4)	7.5% to 4% p.a. (4)
Mortality table	AT 2000, sex specific	AT 2000, sex specific
Disability table	TASA 1927	TASA 1927
Mortality table for disabled persons	AT 49, sex specific	AT 49, sex specific

(1) Inflation decreasing linearly in the next 5 years when it becomes constant.
(2) The Company uses a methodology for computing an equivalent real rate from the future curve of return of the longest term government bonds, considering in the calculation of this rate the maturity profile of the pension and health care liabilities.
(3) Average turnover which varies according to age and time of service.
(4) Decreasing rate attaining in the next 30 years the projected long-term expectations for inflation.

e) Cash contributions and benefit payments

In 2010, the Company contributed US$460 to its pension plans. In 2011, the Company expects contributions to be approximately US$540. Actual contribution amounts are dependent upon investment returns, changes in pension obligations and other economic factors. Additional funding may ultimately be required if investment returns are insufficient to offset increases in plan obligations.

The following benefit payments, which include estimated future service, are expected to be paid by the pension fund in the next 10 years:

	Pension Plans		Health Care Benefits
	Defined Benefits	Variable Contribution
2011	1,687	8	370
2012	1,887	13	411
2013	2,082	19	456
2014	2,287	26	499
2015	2,510	34	552

Commitments and Contingencies Disclosure [Abstract]

Note 18 - Commitments and Contingencies [Text Block]

18. Commitments and Contingencies

a) Commitments

• Commitments for purchase of natural gas

Petrobras entered into an agreement with Yacimientos Petrolíferos Fiscales Bolivianos (YPFB), to purchase a total of 201.9 billion m³ of natural gas during the term of the agreement, undertaking to purchase minimum annual volumes at a price calculated according to a formula indexed to the price of fuel oil. The agreement is valid until 2019 and will be renewed until the total contracted volume has been consumed. The pipeline achieved an average throughput of 22.0 million cubic meters per day during 2010.

In the period between 2002 and 2005, Petrobras bought less than the minimum volume established in the agreement with YPFB and paid US$81, referring to the volumes not transported, the credits for which will be realized through the drawing of future volumes.

The commitments for purchases of gas up to the end of the agreement represent annual average volumes of 24 million cubic meters per day.

In the fourth quarter of 2009 Petrobras and YPFB signed a contractual addendum which regulates the payment of additional amounts to YPFB referring to the quantity of liquids (heavy hydrocarbons) present in the natural gas imported by Petrobras from YPFB through a Gas Supply Agreement (GSA). The addendum establishes additional amounts between US$100 and US$180 per year, applied to the volumes of gas delivered as from May 2007. With respect to 2007, the obligation for additional payment by Petrobras was recorded as a provision and was settled in February 2010. The payment of the amounts referring to subsequent years will only be due after compliance with a condition precedent established in the addendum, which will demand additional negotiations with YPFB.

• Commitments for purchase of oil and oil products

In an effort to ensure procurement of oil products for the Company's customers, the Company currently has several short and long-term normal purchase contracts with maturity dates up to 2019, which collectively obligate it to purchase a minimum of approximately 453,802 barrels of crude oil and oil products per day at market prices.

• Minimum operating lease payments

The Company is committed to make the following minimum payments related to operating leases as of December 31, 2010:

2011	10,645
2012	9,511
2013	7,622
2014	6,232
2015	3,481
2016 and thereafter	10,587
Minimum operating lease payment commitments	48,078

The Company incurred US$5,943, US$3,939 and US$2,983, in rental expense on operating leases at December 31, 2010, 2009 and 2008, respectively.

• Guarantees for concession agreements for petroleum exploration

Petrobras provided guarantees to the ANP for the minimum exploration program defined in the concession contracts for exploration areas, totaling US$3,209 (US$2,355 in 2009). Out of this total, US$2,849 (US$2,042 in 2009) represents a pledge on the oil to be extracted from previously identified fields already in production, for areas in which the Company had already made commercial discoveries or investments. For areas whose concessions were obtained by bidding from the ANP, Petrobras has given bank guarantees totaling US$1,096 through December 31, 2010 (US$333 in 2009).

b) Litigation

Petrobras is subject to a number of commitments and contingencies arising in the normal course of its business. Additionally, the operations and earnings of the Company have been, and may be in the future, affected from time to time in varying degrees by political developments and laws and regulations, such as the Federal Government's continuing role as the controlling shareholder of the Company, the status of the Brazilian economy, forced divestiture of assets, tax increases and retroactive tax claims, and environmental regulations. The likelihood of such occurrences and their overall effect upon the Company are not predictable.

The Company is a defendant in numerous legal actions involving civil, tax, labor, corporate and environment issues arising in the normal course of its business. Based on the advice of its internal legal counsel and management's best judgment, the Company has recorded accruals in amounts sufficient to provide for losses that are considered probable and reasonably estimable. At December 31, 2010 and 2009, the respective amounts accrued by type of claims are as follows:

	As of December 31,
	2010	2009
Labor claims	119	71
Tax claims	361	94
Civil claims	214	272
Commercials claims and other contingencies	66	63
Total	760	500
Current contingencies	-	(31)
Long-term contingencies	760	469

As of December 31, 2010 and 2009, in accordance with Brazilian law, the Company had paid US$1,674 and US$1,158 respectively, into federal depositories to provide collateral for these and other claims until they are settled. These amounts are reflected in the balance sheet as restricted deposits for legal proceedings and guarantees.

b.1) Proceedings classified as probable losses

The principal proceedings, disclosed previously as a possible loss, this quarter are classified as a probable loss, due to the development of the legal case or agreements in progress, as follows:

• ICMS - Sinking of Platform P-36

In 2001, Platform P-36 was imported by Petrobras through temporary admission in accordance with the special regime for imports and exports (REPETRO) which suspends taxation and, therefore, on this occasion state taxes were not due.

With the sinking of the platform, in March 2001, the State of Rio de Janeiro initiated actions for collection of the suspended ICMS through tax foreclosure proceedings as it understands that there will no longer be return of the platform.

In February 2010, with an unfavorable decision at the last level of appeals in the Superior Court of Rio de Janeiro, Petrobras began to evaluate the legal aspects of the suit and the economic aspects of the use of the benefits of tax amnesty established in State Law 5,647, of January 18, 2010, which permits elimination of fines and an expressive decrease in other charges, as well as the possibility of payment with court order debts.

Petrobras adhered to the payment conditions of the aforementioned State Law, fixing the total amount agreed upon with the State of Rio de Janeiro in the amount of US$269, where US$65 was in court order debts.

• Triunfo Agro Industrial S.A and others

During the year 2000, Triunfo Agro Industrial and Others filed a suit against Petrobras, claiming losses and damages as a result of the annulling of a credit assignment transaction - excise tax (IPI) premium. The hearing by the Superior Court of Rio de Janeiro, in the second instance, was unfavorable to Petrobras and approval was denied for the appeal lodged by the Company.

Parallely to the filing of the aforementioned appeals, on September 28, 2010 Petrobras filed a motion for annulling judgment before the Full Bench of the Superior Court of Rio de Janeiro, where it obtained, by 20 votes to one, an injunction that prohibits any withdrawal of values on the part of the plaintiffs.

Based on its legal counsels' advice, the Company has assessed risk of loss to be probable. The maximum estimated exposure as at December 31, 2010, is around US$298, which has been provided. The Company has a balance of deposits in court for this process in the amount of US$205, resulting in a net amount of US$94.

• Notice of infraction - National Agency for Petroleum, Natural Gas and Biofuel - ANP

On July 1, 2010, the Company received a notice that a suit had been filed by ANP, in the amount of US$133, for the alleged miscalculations of the special participation tax basis in the Barracuda and Caratinga fields. On July 15, 2010, Petrobras filed its defense with ANP.

On September 30, ANP presented a new official letter, with a review of the amount for the official notification, as it understands that part of the leasing agreement would not consist of a financing transaction.

On October 28, 2010, Petrobras filed with ANP a request for payment in installments over 30 months in a total amount of US$52, based on the amount established in Official letter 646/2010/SPG, of October 15, 2010. Until December 31, 2010, the Company had paid three installments.

Plaintiff: The Fisherman's Federation of the State of Rio de Janeiro (FEPERJ)

On behalf of its members, FEPERJ is making a number of claims for indemnification as a result of an oil spill in Guanabara Bay which occurred on January 18, 2000. At the time, Petrobras paid out extrajudicial indemnification to all who proved they were fishermen when the accident happened. According to the records of the national fishermen's registry, only 3,339 people were eligible to claim indemnification.

On February 2, 2007, the decision, partially accepting the expert report, was published and, on the pretext of quantifying the amount of the conviction, established that the parameters for the respective calculation based on the criteria would result in an amount of US$661. Petrobras appealed against this decision before the Court of Appeals of Rio de Janeiro, as the parameters stipulated in that the decision had already been specified by the Court of Appeals of Rio de Janeiro, itself. The appeal was accepted. On June 29, 2007, the decision of the First Civil Chamber of the Court of Appeals of the State of Rio de Janeiro was published, denying approval of the appeal filed by Petrobras and approving the appeal lodged by FEPERJ. Special appeals were lodged by Petrobras against this decision, which in a decision handed down on November 19, 2009 by the Superior Court of Justice, were considered fit annul the court decision of the First Civil Chamber of the Superior Court of Rio de Janeiro. Publication of the court decision is being awaited in order to evaluate whether new appeals will be lodged by FEPERJ, or whether the process will be returned to the Superior Court of Rio de Janeiro for a new hearing.

In accordance with the Company's expert assistant calculation, the recorded amount ofUS$30 represents the award that will be set by the court at the end of the process. Based on its legal counsels' advice, the Company has assessed risk of loss to be probable.

Plaintiff: Federal Revenue Department of Rio de Janeiro - Income Tax Withheld at Source related to CLEP

On July 16, 2009, Companhia Locadora de Equipamentos Petrolíferos (CLEP) received an assessment notice questioning the rate of Income Tax Withheld at Source, applicable to the issuing of securities abroad. Possibility of applying the Brazil - Japan Treaty (Dec. 61.889/67). On August 14, 2009, CLEP filed a refutation of this tax assessment notice in the Regional Federal Revenue Office of Rio de Janeiro. On September 3, 2009 the process was remitted to the Control and Hearing Service - DRJ. The maximum updated exposure for Petrobras as at December 31, 2010 is US$250. These amounts refer to the consolidated companies and were offset against the balance of financing in current and non-current liabilities.

The petition for an injunction for renewal of the notification of the decision handed down in the Administrative Process and suspension of the demandability of the debit of income tax withheld at source was dismissed, which permitted the filing of a bill of review on November 19, 2010.

On December 2, 2010, the petition for advance relief was partially granted, suspending the acts of collection of the debit until the new notification of the aforementioned decision is made at the administrative level.

b.2) Proceedings classified as possible losses

On November 23, 1992, Porto Seguro Imóveis Ltda., a minority shareholder of Petroquisa, filed a suit against Petrobras in the State Court of Rio de Janeiro related to alleged losses resulting from the sale of a minority holding by Petroquisa in various petrochemical companies included in the National Privatization Program introduced by Law No. 8,031/90.

In this suit, the plaintiff claims that Petrobras, as the majority shareholder in Petroquisa, should be obliged to reinstate the "loss" caused to the net worth of Petroquisa, as a result of the acts that approved the minimum sale price of its holding in the capital of privatized companies. A decision was handed down on January 14, 1997, that considered Petrobras liable with respect to Petroquisa for losses and damages in an amount equivalent to US$3,406.

In addition to this amount, Petrobras was required to pay the plaintiff 5% of the value of the compensation as a premium (see art. 246, paragraph 2 of Law No. 6,404/76), in addition to attorneys' fees of approximately 20% of the same amount.

In performance of the decision published on June 05, 2006, the Company is now awaiting assignment of the agenda to re-examine the matter relating to the blocking of Petrobras' Special Appeal.

Petrobras filed a special, extraordinary appeal before the Superior Court of Justice (STJ) and the Federal Supreme Court (STF), which were rejected. Petrobras then filed an interlocutory appeal against the decision before the Superior Court of Justice and the Federal Supreme Court.

The Special Appeal offered by Porto Seguro, which sought to bar the processing of the Special Appeal by Petrobras was heard and dismissed in December 2009.

The publication of this decision and judgment of the aforementioned Special Appeal through which Petrobras seeks to totally reverse the sentence is being awaited.

If the award is not reversed, the indemnity estimated to Petroquisa, including monetary correction and interest, would be US$11,422. As Petrobras owns 100% of Petroquisa's share capital, a portion of the indemnity estimated at US$7,539, will not represent a disbursement from Petrobras' Group. In case of loss, Petrobras would have to pay US$571 to Porto Seguro and US$2,284 to Lobo & Ibeas by means of attorney's fees. Based on its legal counsels' advice, the Company has assessed risk of loss to be possible.

Plaintiff: Kalium Mineração S.A.

Kalium Mineração S.A. brought an action for losses and damages and loss of earnings due to the contractual rescission. Considered as with the ground, partially, at the first instance. The two parties lodged appeals which were dismissed. Petrobras is awaiting a hearing of the extraordinary appeal lodged with the Federal Supreme Court and a special appeal with the Superior Court of Justice on September 18, 2003, both of which were admitted. There is also a special appeal by Kalium which is awaiting a hearing. The maximum exposure including monetary restatement for Petrobras as of December 31, 2010 is US$117. Based on its legal counsels' advice, the Company has assessed risk of loss to be possible.

The maximum exposure including monetary restatement for Petrobras as at December 31, 2010, is US$109. Based on its legal counsels' advice, the Company has assessed risk of loss to be possible.

Plaintiff: National Agency for Petroleum, Natural Gas and Biofuel - ANP

Fine for non-compliance with minimum exploration programs - "Rodada Zero". The execution of the fines is suspended through an injunction, pursuant to records of the suit lodged by Petrobras. Through a civil suit, the Company is claiming recognition of its credit resulting from article 22, paragraph 2 of the Petroleum Law, requesting the offsetting of the eventual debt that Petrobras may have with ANP. Both the legal processes, which are being handled jointly, are in the evidentiary stage.

The maximum exposure including monetary restatement for Petrobras as of December 31, 2010 is US$219. Based on its legal counsels' advice, the Company has assessed risk of loss to be possible.

c) Notification from the INSS - joint liability

The Company received various tax assessments related to social security amounts payable as a result of irregularities in presentation of documentation required by the INSS, to eliminate its joint liability in contracting civil construction and other services, stipulated in paragraphs 5 and 6 of article 219 and paragraphs 2 and 3 of article 220 of Decree No. 3,048/99.

In order to guarantee the appeals' filing and/or the obtainment from INSS of Debt Clearance Certificate, US$69 from the amounts disbursed by the Company is recorded as restricted deposits for legal proceedings and guarantees and may be recovered under the respective proceedings in progress, which are related to 332 assessments amounting to US$218 at December 31, 2010. Petrobras' legal department expects a possible defeat regarding these assessments, as it considers the risk of future disbursement to be possible.

Plaintiff: Internal Revenue Service of Rio de Janeiro - Withholding Income Tax related to charter of vessels

Based on this interpretation, overseas remittances for servicing chartering agreements would be subject to withholding tax at the rate of 15% or 25%.

Petrobras has defended itself against these tax assessments. Administrative appeals were lodged with High Court of Appeals for Fiscal Matters, last administrative level, which still await trial.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Note 19 - Derivative Instruments, Hedging and Risk Management Activities [Text Block]

19. Derivative Instruments, Hedging and Risk Management Activities

The Company is exposed to a number of market risks arising from its normal course of business. Such market risks principally involve the possibility that changes in interest rates, foreign currency exchange rates or commodity prices will adversely affect the value of the Company's financial assets and liabilities or future cash flows and earnings.

The Company maintains a corporate risk management policy that is executed under the direction of the Company's executive officers. In 2004, the Executive Committee of Petrobras set up the Risk Management Committee composed of executive managers from all the business departments and from a number of corporate departments. This committee, as well as having the objective of assuring integrated management of exposures to risks and formalizing the main guidelines for the Company's operation, aims at concentrating information and discussing actions for risk management, facilitating communication with the executive offices and the Board of Directors in aspects related to best corporate governance practices.

The risk management policy of the Petrobras System aims at contributing towards an appropriate balance between its objectives for growth and return and its level of risk exposure, whether inherent to the exercise of its activities or arising from the context within which it operates, so that, through effective allocation of its physical, financial and human resources the Company may attain its strategic goals.

The Company may use derivative and non-derivative instruments to implement its corporate risk management strategy. However, by using derivative instruments, the Company exposes itself to credit and market risk. Credit risk is the failure of a counterparty to perform under the terms of the derivative contract. Market risk is the possible adverse effect on the value of an asset or liability, including financial instruments that results from changes in interest rates, currency exchange rates, or commodity prices. The Company addresses credit risk by restricting the counterparties to such derivative financial instruments to major financial institutions. Market risk is managed by the Company's executive officers. The Company does not hold or issue financial instruments for trading purposes.

a) Commodity price risk management

The Company is exposed to commodity price risks as a result of the fluctuation of crude oil and oil product prices. The Company's commodity risk management activities are primarily undertaking through the uses of future contracts traded on stock exchanges; and options and swaps entered into with major financial institutions. The Company does not use derivatives contracts for speculative purposes.

The Company does not usually use derivatives to manage overall commodity price risk exposure, taking into consideration that the Company's business plan uses conservative price assumptions associated to the fact that, under normal market conditions, price fluctuations of commodities do not represent a substantial risk to achieving strategic objectives.

The decision to enter into hedging or non-hedging derivatives is reviewed periodically and recommended, or not, to the Risk Management Committee. If entering into derivative is indicated, in scenarios with a significant probability of adverse events, and such decision is approved by the Board of Directors, the derivative transactions should be carried out with the aim of protecting the Company's solvency, liquidity and execution of the corporate investment plan, considering an integrated analysis of all the Company's risk exposures.

Outstanding derivatives contracts were entered into in order to mitigate price risk exposures from specific transactions, in which positive or negative results in the derivative transactions are totally or partially offset by the opposite result in the physical positions. The transactions covered by commodity derivatives are: certain cargoes traded from import and export operations and transactions between different geographical markets.

As a result of the Company currently price risk management, the derivatives are contracted as short term operations, to mitigate the price risk of specific forecasted transactions. The operations are carried out on the New York Mercantile Exchange (NYMEX) and the Intercontinental Exchange (ICE), as well as on the international over-the-counter market.

The Company's exposure from these contracts is limited to the difference between the contract value and market value on the volumes contracted. Crude oil future contracts are marked-to-market and related gains and losses are recognized in currently period earnings, irrespective of when the physical crude sales occur.

The main parameters used in risk management for variations of Petrobras' oil and oil products prices are the cash flow at risk (CFAR) for medium-term assessments, Value at Risk (VAR) for short-term assessments, and Stop Loss. Corporate limits are defined for VAR and Stop Loss.

The hedges settled during the period from January to December 2010 corresponded to approximately 98% of the traded volume of imports and exports to and from Brazil plus the total volume of the products traded abroad.

The main counterparts of operations for derivatives for oil and oil products are the New York Stock Exchange (NYMEX), Intercontinental Exchange (ICE), BP North America Chicago, Morgan Stanley and Shell (Stasco).

The commodity derivatives contracts are reflected at fair value as either assets or liabilities on the Company's consolidated balance sheets recognizing gain or losses in earnings, using market to market accounting, in the period of change.

As of December 31, 2010, the Company had the following outstanding commodity derivative contracts that were entered into:

	Notional amount in
Commodity Contracts	thousands of bbl*
Maturity 2010	As of December 31, 2010
Futures and Forwards contracts	(8,216)
Options contracts	(1,679)
* A negative notional value represents a sale position.

b) Foreign currency risk management

Exchange risk is one of the financial risks that the Company is exposed to and it originates from changes in the levels or volatility of the exchange rate. With respect to the management of these risks, the Company seeks to identify and handle them in an integrated manner, seeking to assure efficient allocation of the resources earmarked for the derivative.

Taking advantage of operating in an integrated manner in the energy segment, the Company seeks, primarily, to identify or create "natural risk mitigation", benefiting from the correlation between its income and expenses. In the specific case of exchange variation inherent to the contracts with the cost and remuneration involved in different currencies, this natural risk mitigation is carried out through allocating the cash investments between the real and the US dollar or another currency.

The management of risks is done for the net exposure. Periodical analyses of the exchange risk are prepared, assisting the decisions of the executive committee. The exchange risk management strategy involves the use of derivative instruments to minimize the exchange exposure of certain Company's obligations.

Petrobras Distribuidora (wholly owned subsidiary) entered into an over the counter contract, not designated as hedge accounting, for covering the trading margins inherent to exports (aviation segment) for foreign clients. The objective of the operation, contracted contemporaneously with the definition of the cost of the products exported, is to lock the trading margins agreed with the foreign clients. Internal policy limits the volume of derivative contracts to the volume of products exported.

The volume of hedge executed for the exports occurring between January and December 2010 represented 52.7% of the total exported by Petrobras Distribuidora. The settlements of the operations that matured between January 1 and December 31, 2010 generated a positive result for the Company of US$6.

The over the counter contract is reflected at fair value as either assets or liabilities on the Company's consolidated balance sheets recognizing gains or losses in earnings, using market to market accounting, in the period of change.

As of December 31, 2010, the Company had the following foreign currency derivative contracts, not designated as hedging accounting, that were entered into:

Foreign Currency	Notional Amount
Maturing in 2009	US$ million
Sell USD / Pay BRL	(8)

Cash flow hedge

In September 2006, the Company contracted a hedge known as a cross currency swap for coverage of the bonds issued in Yens in order to fix the Company's costs in this operation in dollars. In a cross currency swap there is an exchange of interest rates in different currencies. The exchange rate of the Yen for the US dollar is fixed at the beginning of the transaction and remains fixed during its existence. The Company does not intend to settle these contracts before the end of the term.

The Company has elected to designate its cross currency swap as cash flow hedges. Both at the inception of a hedge and on an ongoing basis, a cash flow hedge must be expected to be highly effective in achieving offsetting cash flows attributable to the hedged risk during the term of the hedge. Derivative instruments designated as cash flow hedges are reflected as either assets or liabilities on the Company's consolidated balance sheets. Change in fair value, to the extent the hedge is effective, is reported in accumulated other comprehensive income until the cash flows of the hedged item occurs.

Effectiveness tests are conducted quarterly in order to measure how the changes in the fair value or the cash flow of the hedged items are being absorbed by the hedge mechanisms. The effectiveness calculation indicated that the cross currency swap is highly effective in offsetting the variation in the cash flows of the bonds issued in Yens.

As of December 31, 2010, the Company had the following cross currency swap, which was entered into:

Cross Currency Swaps Maturing in 2016	%	Notional Amount (Million)
Fixed to fixed
Average Pay Rate (USD)	5.69	US$298
Average Receive Rate (JPY)	2.15	JPY$35,000

c) Embedded derivatives

Derivatives embedded within other financial instruments or other host contracts are treated as separate derivatives when they have a price based on an underlying that is not clearly and closely related to the asset being sold or purchased. The assessment is made only at the inception of the contracts. Such derivatives are separately from the host contract and recognized at fair value with changes in fair value recognized in earnings.

Sale of ethanol

Petrobras through its subsidiary, Petrobras International Finance (PifCo), entered into a sales contract of 143,000 m³ per year of ethanol for ten years subject to renegotiation of prices and termination after the first five years. The sales price formula is based on both quotations: ethanol and naphtha.

Naphtha is an extraneous underlying to the cost and fair value of the asset being sold. The embedded derivative was bifurcated from the host contract and recognized at fair value through earnings.

The Company determined the fair value based on the difference between the spreads for naphtha and ethanol. The market quotations used in the measurement were obtained from the CBOT (Chicago Board of Trade) future market. In accordance with ASC 820, fair value was classified at level 3.

Forward Contract	Notional amount in thousand m3	Fair Value	VAR	Maturity
Long position	715	US$32	1	2016

d) Interest rate risk management

The Company's interest rate risk is a function of the Company's long-term debt and to a lesser extent, its short-term debt. The Company's foreign currency floating rate debt is principally subject to fluctuations in LIBOR and the Company's floating rate debt denominated in Reais is principally subject to fluctuations in the Brazilian long-term interest rate (TJLP) as fixed by the National Monetary Council. The Company currently does not utilize derivative financial instruments to manage its exposure to fluctuations in interest rates.

Domestic and International Acquisitions [Abstract]

Note 17 - Domestic and International Acquisitions [Text Block]

17. Acquisition/Sales of Assets and Interests

a) Goodwill

Goodwill represents the excess of the purchase price over the estimated fair value of the net assets acquired in the acquisition of a business. In accordance with Codification Topic 350 -Goodwill and Other Intangible Assets ("ASC 350"), the Corporation's goodwill is not amortized, but is tested for impairment at a reporting unit level, which is an operating segment or one level below an operating segment. The Company conducts its annual goodwill impairment review in the fourth quarter of each year and whenever events and changes in circumstances suggest that the carrying amount may not be recoverable.

Goodwill impairment encompasses a two step approach. In the first step the Company compares the fair value of the reporting unit with its carrying amount, including goodwill. If the fair value is lower than the carrying amount including goodwill, there is an indication of impairment loss that is measured by performing the second step. In the second step, the estimated fair value from the first step is used as the purchase price in a hypothetical acquisition of the reporting unit. Purchase business combination accounting rules are followed to determine a hypothetical purchase price allocation to the reporting unit's assets and liabilities. The residual amount of goodwill that results from this hypothetical purchase price allocation is compared to the recorded amount of goodwill for the reporting unit, and the recorded amount is written down to the hypothetical amount, if lower.

Change in the balance of goodwill for the years ended December 31, 2010 and 2009:

Balance as of December 31, 2008	118
Cumulative translation adjustment	21
Balance as of December 31, 2009	139

e) Sale of assets and other information

• Sale of the San Lorenzo refinery and part of the distribution network in Argentina

On May 4, 2010, Petrobras Argentina S.A. (formerly Petrobras Energia S.A.) approved the terms and conditions of the agreement for the sale to Oil Combustibles S.A. of refining and distribution assets in Argentina. The deal comprises a refinery located in San Lorenzo in the province of Santa Fé, a fluvial unit and a fuel trading network connected to this refinery, consisting of 360 sales points and associated wholesaler clients.

The offer for the aforementioned assets was approximately US$36. In addition, on the closing date the petroleum inventories and the different products will be sold to Oil Combustibles for approximately US$74. The total amount of the transaction is estimated at around US$110.

The transaction is in the process of approval by the administrative authorities required by the prevailing legislation in Argentina.

The transaction does not consider the sale of the reformer unit that Petrobras Argentina has in its Puerto General San Martín Petrochemical Complex.

• Acquisition of Gás Brasiliano Distribuidora S.A.

On May 26, 2010 Petrobras S.A., through its subsidiary Petrobras Gás S.A. (Gaspetro), entered into an agreement with Enti Nazionale Idrocarburi S.p.A. (ENI) for acquisition of 100% of the shares of Gas Brasiliano Distribuidora S.A. (GBD), for the approximate amount of US$250, subject to adjustments due to the value of the company's working capital on the date of settlement of the transaction.

Transfer of the control will be made only after the conclusion of the transaction, which is subject to approval by the Regulatory Agency for Sanitation and Energy of the State of Sao Paulo (ARSESP).

• Operations in Ecuador

In 2006, the Ecuadorian government began a series of tax and regulatory reforms with respect to hydrocarbon activities, which significantly affected the agreements for participation in exploration blocks. As from November 24, 2010, all the exploration agreements in force until then had to migrate to service agreements.

Petrobras Argentina S.A. (PESA), through Sociedade Ecuador TLC S.A., holds a 30% interest in the exploration agreements for Block 18 and the unified Palo Azul field, located in the Oriente basin of Ecuador.

PESA decided not to accept the final proposal to migrate its agreements to the new contractual model, thus it is the responsibility of the Ecuadorian Government to indemnify the investments made in those exploration blocks.

Also in Ecuador, PESA has a Ship or Pay agreement entered into with Oleoducto de Crudos Pesados Ltd (OCP) for transporting oil, which is in force since November 10, 2003 with an effective term of 15 years. On account of the commitments assumed for the transport capacity contracted and not used due to the decrease in the volume of oil traded, it recorded liabilities of US$85 at December 31, 2010.

a) Accounting treatment of Assignment Agreement ("Cessão Onerosa")

On September 3, 2010, Petrobras entered into an agreement with the Brazilian federal government (Assignment Agreement), under which the government assigned to the Company the right to conduct research activities and the exploration and production of fluid hydrocarbons in specified pre-salt areas, subject to a maximum production of five billion barrels of oil equivalent up to 40 years renewable for more five years upon certain conditions.

The Assignment Agreement was approved by the Company's Board of Directors and by the minority shareholders, following a valuation procedure based on, among other factors, an assessment prepared by independent third party experts.

The total purchase price of the rights acquired under the Assignment Agreement was US$43,868, paid to the Federal Government through funds obtained by the global offering of shares of the Company (see Note 16(a)), US$39,768 through the transfer of Brazilian Treasury Securities and the remaining US$4,100 in cash.

In accordance with ASC 932 "Extractive Activities - Oil and Gas", the rights acquired by the Company were recognized as Property Plant & Equipment (long-term asset) as acquisition costs. The acquisition cost will be depreciated based on the unit-of-production method during the period of production of the related reserves and will also be subject to the impairment test. After the production of all the volumes that we were entitled, the acquisition costs will be completely depreciated.

The Assignment Agreement provides for a subsequent revision of the volume and the price, based on an independent third party assessment. If the contract parties determine that the value of the rights acquired is higher than the initial purchase price, the Company may either pay the difference to the Brazilian federal government, in which case is expected the recognition of the difference as Property Plant & Equipment (long-term asset), or reduce the total volume acquired under the contract, in which case there would be no impact on the balance sheet. If the contract parties determine that the value of the rights acquired is lower than the initial purchase price, the Brazilian federal government will pay for the difference in cash and/or bonds, dependent of Government Budget conditions and it is expected a reduction of the amount originally recorded as Property Plant & Equipment (long-term asset) by the amount received from the Brazilian federal government.

The knowledge of the reserves and the geological uncertainties remain unchanged since the signing of the assignment agreement. The final value of the cost of the assignment will depend mainly on full knowledge: of the reserves, of the production scenarios and the technologies to be developed, which should occur not later than 2014, the deadline stipulated for the declaration of commercialization.

The Company will record any adjustment to the acquisition cost, when it is probable and determinable it will pay or receive in the future, amounts as a result of the subsequent revision.

b) Codification Topic 410 - Asset Retirement Obligations

In accordance with Codification Topic 410-20, adopted by Petrobras since January 2003, the fair value of asset retirement obligations are recorded as liabilities on a discounted basis when they are incurred, which is typically at the time the related assets are installed. Amounts recorded for the related assets will be increased by the amount of these obligations and depreciated over the related useful lives of such assets. Over time, the amounts recognized as liabilities will be accreted for the change in their present value until the related assets are retired or sold.

Measurement of asset retirement obligations is based on currently enacted laws and regulations, existing technology and site-specific costs. There are no assets legally restricted to be used in the settlement of asset retirement obligations.

A summary of the annual changes in the asset retirement obligations is presented as follows:

	Liabilities
Balance as of December 31, 2008	2,825
Accretion expenses	164
Liabilities incurred	24
Liabilities settled	(4)
Revision of provision	(955)
Cumulative translation adjustment	758
Balance as of December 31, 2009	2,812
Accretion expenses	137
Liabilities incurred	1,088
Liabilities settled	(124)
Revision of provision	(858)
Cumulative translation adjustment	139
Balance as of December 31, 2010	3,194

c) Impairment

For the years ended December 31, 2010, 2009 and 2008, the Company recorded impairment charges of US$402, US$319 and US$519, respectively. During 2010, the impairment charge was primarily related to producing properties in Brazil (US$346) and due to the impairment of assets held for sale, referring to the refining and distribution segments in Argentina (US$56). The petroleum and natural gas fields that presented losses already had high maturity levels and, consequently, produced insufficient petroleum and gas to cover production costs. This factor had a reducing effect on the economic analysis that led to the recording of a provision for loss through devaluation in some fields.

At December 31, 2010 and 2009, long-term receivables include US$642 and US$633, respectively relating to payments made by the Company to suppliers and subcontractors on behalf of certain contractors. These contractors had been hired by the subsidiary Brasoil for the construction/conversion of vessels into FPSO ("Floating Production, Storage and Offloading") and FSO ("Floating, Storage and Offloading") and failed to make the payments to their suppliers and subcontractors. The Company made the payments to avoid further delays in the construction/conversion of the vessels and consequent losses to Brasoil.

The Company's management has determined that these payments can be reimbursed, since they represent Brasoil's rights with respect to the contractors, for which reason judicial action was filed with international courts to seek reimbursement. However, as a result of the uncertainties related to the realization of such receivables, the Company recorded an allowance for all credits not backed by collateral. Such allowance amounted to US$570 and US$561 as of December 31, 2010 and 2009, respectively.

Raising of funds for PifCo

On January 27, 2011, the Petrobras International Finance Company (PifCo) concluded the issuing of US$6 billion in Global Notes on the international capital market, with maturity on January 27, 2016, 2021 and 2041, interest rates of 3.875%, 5.375% and 6.750% p.a., respectively, and half-yearly payment of interest as from July 27, 2011.The capital raised will be used for corporate purposes and the financing of the investments established in the 2010-2014 Business Plan, and an appropriate capital structure and the level of financial leverage will be maintained in line with the Company's goals.

This financing had issuing costs estimated at approximately US$18, a discount of US$21 and effective interest rates of 4.01%, 5.44% and 6.84% p.a., respectively. Global Notes constitute unsecured, unsubordinated obligations for PifCo and have the complete, unconditional guarantee of Petrobras.

Purchase option for Companhia Mexilhão do Brasil (CMB) - Project Mexilhão

On January 12, 2011, Petrobras exercised its purchase option for the shares of SPE Companhia Mexilhão do Brasil and now guarantees the financing taken out by the SPE from BNDES (National Bank of Economic and Social Development).

Merger of Comperj Petroquímicos Básicos S.A. (UPB) and Comperj PET S.A. (PET) into Petrobras

On January 31, 2011, the General Shareholders' Meeting of Petrobras approved the merger of Comperj Petroquímicos Básicos S.A. and Comperj PET S.A. into its equity, without a capital increase. With the merger of these companies, the corporate structure of Comperj will be simplified, minimizing costs and favoring reallocation of investments.

Special participation in the Albacora, Carapeba, Cherne, Espadarte, Marimbá, Marlim, Marlim Sul, Namorado, Pampo and Roncador Fields- Campos Basin

This special participation was established by Brazilian Petroleum Law 9478/97 and is paid as a form of compensation for oil production activities and is levied on high volume production fields. The method used by Petrobras to calculate the special participation due for the abovementioned fields is based on a legally legitimate interpretation of Ordinance 10 of January 14, 1999, approved by the National Petroleum Agency (ANP).

Special participation in the Albacora, Carapeba, Cherne, Espadarte, Marimbá, Marlim, Marlim Sul, Namorado, Pampo and Roncador Fields- Campos Basin (Continued)

Petrobras received notice from ANP, which instituted an administrative process and established payment of new sums of money considered to be owed for the period between the first quarter of 2005 and the first quarter of 2010, referring to amounts that had been underpaid by the concessionaire, totaling R$ 365 (principal, without fine and interest).

On February 22, 2011, Petrobras filed for a hearing for dismissal of the aforementioned official notification. If ANP's administrative decision is maintained, Petrobras shall evaluate the possibility of a court suit to suspend and annul the collection of the differences of the special participation.

If the ANP's administrative decision is maintained, Petrobras would consider legal action to suspend and cancel the charge of the differences of the special participation.

Oil and Gas Exploration and Production Industries Disclosures [Abstract]

Note 23 - Accounting for Suspended Exploratory Wells [Text Block]

23. Accounting for Suspended Exploratory Wells

The Company's accounting for exploratory drilling costs is governed by Codification Topic 932 - Extractive Activities - Oil and Gas. Costs the Company has incurred to drill exploratory wells that find commercial quantities of oil and gas are carried as assets on its balance sheet under the classification "Property, plant and equipment" as unproved oil and gas properties. Each year, the Company writes-off the costs of these wells that have not found sufficient proved reserves to justify completion as a producing well, unless: (1) the well is in an area requiring major capital expenditure before production can begin; and (2) additional exploratory drilling is under way or firmly planned to determine whether the capital expenditure is justified.

As of December 31, 2010, the total amount of unproved oil and gas properties was US$7,846, and of that amount US$4,838 (US$2,911 of which related to projects in Brazil) represented costs that had been capitalized for more than one year, which generally are a result of: (1) extended exploratory activities associated with offshore production; and (2) the transitory effects of deregulation in the Brazilian oil and gas industry, as described below.

In 1998, the Company's government-granted monopoly ended and the Company signed concession contracts with the Agência Nacional de Petróleo (National Petroleum Agency, or ANP) for all of the areas the Company had been exploring and developing prior to 1998, which consisted of 397 concession block. Since 1998, the ANP has conducted competitive bidding rounds for exploration rights, which has allowed the Company to acquire additional concession blocks. After a concession block is found to contain a successful exploratory well, the Company must submit an "Evaluation Plan" to the ANP for approval. This Evaluation Plan details the drilling plans for additional exploratory wells. An Evaluation Plan is only submitted for those concession areas where technical and economic feasibility analyses on existing exploration wells evidence justification for completion of such wells. Until the ANP approves the Evaluation Plan, the drilling of additional exploratory wells cannot commence. If companies do not find commercial quantities of oil and gas within a specific time period, generally 4-6 years depending on the characteristics of the exploration area, then the concession block must be relinquished and returned to the ANP. Because the Company was required to assess a large volume of concession blocks in a limited time frame even when an exploratory well has found sufficient reserves to justify completion and additional wells are firmly planned, finite resources and expiring time frames in other concession blocks have dictated the timing of the planned additional drilling.

The following table shows the net changes in capitalized exploratory drilling costs during the years ended December 31, 2010 and 2009:

Unproved oil and gas properties (*)
	Year ended December, 31
	2010	2009
Beginning balance at January 1	5,902	3,558
Additions to capitalized costs pending determination of proved reserves	4,560	3,383
Capitalized exploratory costs charged to expense	(1,201)	(1,251)
Transfers to property, plant and equipment based on the determination of the proved reserves	(1,659)	(613)
Cumulative translation adjustment	244	825
Ending balance at December 31,	7,846	5,902

(*) Amounts capitalized and subsequently expensed in the same period have been excluded from the above table.

The following table provides an aging of capitalized exploratory well costs based on the date the drilling was completed and the number of projects for which exploratory well costs have been capitalized for a period greater than one year since the completion of the drilling:

Aging of capitalized exploratory well costs
	Year ended December 31,
	2010	2009
Capitalized exploratory well costs that have been capitalized for a period of one year or less	3,008	2,092
Capitalized exploratory well costs that have been capitalized for a period greater than one year	4,838	3,810
Ending balance	7,846	5,902
Number of projects that have exploratory well costs that have been capitalized for a period greater than one year	84	95

Of the US$4,838 for 84 projects that include wells suspended for more than one year since the completion of drilling, approximately US$1,243 are related to wells in areas for which drilling was under way or firmly planned for the near future and that the Company has submitted an "Evaluation Plan" to the ANP for approval and approximately US$2,416 incurred in costs for activities necessary to assess the reserves and their potential development.

The US$ 4,838 of suspended wells cost capitalized for a period greater than one year as of December 31, 2010, represents 150 exploratory wells and the table below contains the aging of these costs on a well basis:

Aging based on drilling completion date of individual wells:

	Million of dollars	Number of wells
2009	2,005	80
2008	1,428	38
2007	372	11

Accounting Policies [Abstract]

Note 2 - Summary of Significant Accounting Policies [Text Block]

2. Summary of Significant Accounting Policies

In preparing these consolidated financial statements, the Company has followed accounting policies that are in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"). The preparation of these financial statements requires the use of estimates and assumptions that affect the assets, liabilities, revenues and expenses reported in the financial statements, as well as amounts included in the notes thereto.

Estimates adopted by management include: oil and gas reserves, pension and health care liabilities, depreciation, depletion and amortization, abandonment costs, fair value of financial instruments, contingencies and income taxes. While the Company uses its best estimates and judgments, actual results could differ from those estimates as future confirming events occur.

Certain prior years amounts have been reclassified to conform to current year presentation standards. These reclassifications are not significant to the consolidated financial statements and had no impact on the Company's net income.

Events subsequent to December 31, 2010 were evaluated until the time of the Form 6-K filing with the Securities and Exchange Commission.

a) Basis of financial statements preparation

The accompanying consolidated financial statements of Petróleo Brasileiro S.A. - Petrobras (the Company) have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) and the rules and regulations of the Securities and Exchange Commission (SEC). U.S. GAAP differs in certain respects from International Financial Reporting Standards (IFRS), as issued by International Financial Reporting Standards Board (IASB) and applied by Petrobras in its statutory financial statements prepared in accordance with Brazilian Corporate Law and regulations promulgated by the Brazilian Securities and Exchange Commission (CVM). The Brazilian Corporation Law was amended in 2007 to permit Brazilian GAAP to converge with International Financial Reporting Standards, and Petrobras chose to present its financial statements for local purposes for the first time in accordance with IFRS in the first quarter of 2010 (see more details in Note 2 - item p).

The U.S. dollar amounts for the years presented have been translated from the Brazilian Real amounts in accordance Accounting Standard Codification - ASC Topic 830 - Foreign Currency Matters as applicable to entities operating in non-hyperinflationary economies. Transactions occurring in foreign currencies are first remeasured to the Brazilian Real and then translated to the U.S. dollar, with remeasurement gains and losses being recognized in the statements of income. While Petrobras has selected the U.S. Dollar as its reporting currency, the functional currency of Petrobras and all Brazilian subsidiaries is the Brazilian Real. The functional currency of Petrobras International Finance Company - PifCo and some subsidiaries and certain of the special purpose companies that operate in the international economic environment is the U.S. dollar, and the functional currency of Petrobras Argentina is the Argentine Peso.

The Company has translated all assets and liabilities into U.S. dollars at the current exchange rate (R$1.666 and R$1.741 to US$1.00 at December 31, 2010 and 2009, respectively), and all accounts in the statements of income and cash flows (including amounts relative to local currency indexation and exchange variances on assets and liabilities denominated in foreign currency) at the average rates prevailing during the year. The net translation gain in the amount of US$6,796 in 2010 (net translation gain in 2009 - US$22,589 and net translation loss in 2008 - US$20,001) resulting from this remeasurement process was excluded from income and presented as a cumulative translation adjustment ("CTA") within "Accumulated other comprehensive income" in the consolidated statements of changes in shareholders' equity.

b) Principles of consolidation

The consolidated financial statements include the accounts of the Company and all majority-owned subsidiaries in which (a) the Company directly or indirectly has either a majority of the equity of the subsidiary or otherwise has controlling financial interest, or (b) the Company has determined itself to be the primary beneficiary of a variable interest entity in accordance with Codification Topic 810-10-25 ("Variable Interest Entities"). All significant intercompany balances and transactions have been eliminated in consolidation.

(1) At December 31, 2010, the Company had amounts invested in the Petrobras Group's NonStandardized Credit Rights Investment Fund (Fundo de Investimento em Direitos Creditórios não-padronizados do Sistema Petrobras - "FIDC-NP"). This investment fund is predominantly intended for acquiring credit rights, performed and/or non-performed, in the Petrobras System companies, and aims to optimize the Company's cash management.

c) Cash and cash equivalents

Cash and cash equivalents consist of highly liquid investments that are readily convertible into cash and have an original maturity of three months or less at date of acquisition.

d) Marketable securities

Marketable securities have been classified by the Company as available-for-sale, held-to-maturity or trading based upon intended management's strategies with respect to such securities. The Company classifies and accounts for marketable securities under ASC Topic 320 - Investments:

Trading securities, which are marked-to-market through current period earnings;

· Available-for-sale securities, which are marked-to-market through other comprehensive income;

· Held-to-maturity securities, which are recorded at amortized cost.

The interest and monetary restatement of the securities are recorded in the statement of income. There were no material transfers between categories.

e) Inventories

Inventories are stated as follows:

· Raw material comprises mainly the stocks of petroleum, which are stated at the average value of the importing or production costs, adjusted, when applicable, to their realization value;

· Oil products and fuel alcohol are stated, respectively, at average refining and purchase cost, adjusted when applicable to their realization value;

· Materials and supplies are stated at average purchase cost, not exceeding replacement value and imports in transit are stated at identified cost.

f) Investments in non-consolidated companies

The Company uses the equity method of accounting for all long-term investments for which it owns between 20% and 50% of the investee's outstanding voting stock or has the ability to exercise significant influence over operating and financial policies of the investee without controlling it. The equity method requires periodic adjustments to the investment account to recognize the Company's proportionate share in the investee's results, reduced by receipt of investee's dividends.

g) Property, plant and equipment

· Costs incurred in oil and gas producing activities

The costs incurred in connection with the exploration, development and production of oil and gas are recorded in accordance with the "successful efforts" method. This method requires that costs the Company incurs in connection with the drilling of developmental wells and facilities in proved reserve production areas and successful exploratory wells be capitalized. In addition, costs the Company incurs in connection with geological and geophysical activities are charged to the statements of income in the year incurred, and the costs relating to exploratory dry wells on unproved reserve properties are charged to the statements of income when determined as dry or uneconomical.

· Capitalized costs

The capitalized costs are depreciated based on the unit-of-production method using proved developed reserves. These reserves are estimated by the Company's geologists and petroleum engineers in accordance with SEC standards and are reviewed annually or more frequently when there are indications of significant changes.

· Property acquisition costs

Costs of acquiring developed or undeveloped leaseholds including lease bonus, brokerage, and other fees are capitalized. The costs of undeveloped properties that become productive are transferred to a producing property account.

· Exploratory costs

Exploratory wells that find oil and gas in an area requiring a major capital expenditure before production begins are evaluated annually to assure that commercial quantities of reserves have been found or that additional exploration work is underway or planned. Exploratory costs related to areas where commercial quantities have been found are capitalized, and exploratory costs where additional work is underway or planned continue to be capitalized pending final evaluation. Exploratory well costs not meeting either of these tests are charged to expense. All other exploratory costs (including geological and geophysical costs) are expensed as incurred. Exploratory dry holes are expensed.

· Development costs

Costs of development wells including wells, platforms, well equipment and attendant production facilities are capitalized.

· Production costs

Costs incurred with producing wells are recorded as inventories and are expensed when the products are sold.

· Abandonment costs

The Company makes its annual reviews and revision of its estimated costs associated with well abandonment and the demobilization of oil and gas production areas, considering new information about date of expected abandonment and revised cost estimates to abandon. The changes in estimated asset retirement obligation are principally related to the commercial declaration of new fields, certain changes in cost estimates, and revisions to abandonment information provided for non-operated joint ventures, considering the useful economic life of the fields and the expected cash flows, to present value, at a rate of interest free of risks, adjusted by the Petrobras risk.

· Depreciation, depletion and amortization

Depreciation, depletion and amortization of leasehold costs of producing properties are recorded using the unit-of-production method applied on a field by field basis as a ratio of proved developed reserves. Production platform under capital lease which is not tied to the respective wells, are depreciated on a straight-line basis over the estimated useful lives of the platforms. Depreciation, depletion and amortization of all other capitalized costs (both tangible and intangible) of proved oil and gas producing properties is recorded using the unit-of-production method applied on a field by field basis as a ratio of proved developed reserves produced. The straight-line method is used for assets with a useful life shorter than the life of the field.

Other plant and equipment are depreciated on a straight line basis, based on the following estimated useful lives:

Class of assets	Useful life
	average weighted
Buildings and improvements	25 years (25-40 years)
Equipment and other assets	20 years (3-31 years)

· Impairment

In accordance with Codification Topic 360-10, management reviews long-lived assets, primarily property, plant and equipment to be used in the business and capitalized costs relating to oil and gas producing activities, whenever events or changes in circumstances indicate that the carrying value of an asset or group of assets may not be recoverable on the bases of undiscounted future cash flows. The reviews are carried out at the lowest level of assets to which the Company is able to attribute identifiable future cash flows. The net book value of the underlying assets is adjusted to their fair value using a discounted future cash flows model, if the sum of the expected undiscounted future cash flows is less than the book value.

The main assumptions of cash flows are: prices based on last strategic plan presented, production curves associated to existent projects comprising the Company's portfolio, operating market costs and investments needed for projects conclusion.

· Maintenance and repairs

Maintenance and repairs, that do not embody significant improvements, are expensed as incurred, as well as planned major maintenances. Expenditures which appreciably extend the life, increase the capacity, or improve the efficiency of existing property are capitalized.

· Capitalized interest

Interest is capitalized in accordance with Codification Topic 835-20 - Capitalization of Interest Cost. Interest is capitalized on specific projects when a construction process involves considerable time and involves major capital expenditures. Capitalized interest is allocated to property, plant and equipment and amortized over the estimated useful lives or unit-of-production method of the related assets. Interest is capitalized at the Company's weighted average cost of borrowings.

h) Revenues, costs and expenses

Revenue from sales of crude oil and oil products, petrochemical products, natural gas and other related products is recognized when title passes to the customer, because at that time the amount can be reasonably measured, collectibility is reasonably assured, persuasive evidence of an arrangement exists, the seller's price to the buyer is fixed or determinable and the significant risks and rewards of ownership have been transferred. Title is transferred to the customer when delivery occurs pursuant to the terms of the sales contracts. Revenues from the production of natural gas properties in which Petrobras has an interest with other producers are recognized based on the actual volumes sold during the period. Subsequent adjustments to revenues based on production sharing agreements or volumetric delivery differences are not significant. Costs and expenses are accounted for on an accrual basis. Purchases and sales of inventory with the same counterparty (buy/sell arrangements) are combined and recorded on a net basis and reported in "Cost of Sales" on the Consolidated Statements of Income.

i) Income taxes

The Company accounts for income taxes in accordance with Codification Topic 740 -Accounting for Income, which requires an asset and liability approach to recording current and deferred taxes. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to the differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

The Company records the tax benefit of all net operating losses as a deferred tax asset and recognizes a valuation allowance for any part of this benefit which management believes will not be recovered against future taxable income using a "more likely than not" criterion.

In accordance with Codification Topic 740-10, the Company recognizes the effect of an income tax position only if that position is more likely that not of being sustained upon examination, based on technical merits of the position. A recognized income tax position is measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgement occurs. The Company records interests and penalties related to unrecognized tax benefits in "Other expenses".

j) Employees' postretirement benefits

The Company sponsors a contributory defined-benefit pension plan covering substantially all of its employees, which is accounted and disclosured for by the Company in accordance with Codification Topic 715 - Compensation-Retirement Benefits.

In addition, the Company provides certain health care benefits for retired employees and their dependents. The cost of such benefits is recognized in accordance with Codification Topic 715 - Compensation-Retirement Benefits.

The Company also contributes to the Brazilian pension and government sponsored pensions of international subsidiaries, social security and redundancy plans at rates based on payroll, and such contributions are expensed as incurred. Further indemnities may be payable upon involuntary severance of employees but, based on current operating plans, management does not believe that any amounts payable under this plan will be significant.

k) Earnings per share

Earnings per share are computed using the two-class method, which is an earnings allocation formula that determines earnings per share for both preferred shares, which are participating securities and common shares as if all of the net income for each year had been distributed in accordance with a predetermined formula described in Note 16(f).

l) Accounting for derivatives and hedging activities

The Company applies Codification Topic 815 - Derivatives and Hedging, together with its amendments and interpretations, referred to collectively herein as "ASC 815". These rules require that all derivative instruments be recorded in the balance sheet of the Company as either an asset or a liability and measured at fair value. ASC 815 requires that changes in the derivative's fair value be recognized in the income statement unless specific hedge accounting criteria are met; and the Company designates. For derivatives designated as accounting hedges, fair value adjustments are recorded either in the income statements or "Accumulated other comprehensive income", a component of shareholders' equity, depending upon the type of accounting hedge and the degree of hedge effectiveness.

The Company uses derivative financial instruments, not designated as hedge accounting, to mitigate the risk of unfavorable price movements for crude oil purchases. These instruments are marked-to-market with the associated gains or losses recognized as "Financial income" or "Financial expenses".

The Company may also use non-hedging derivatives to mitigate the risk of unfavorable exchange-rate movements on its foreign currency-denominated funding. Gains and losses from changes in the fair value of these contracts are recognized as "Financial income" or "Financial expenses".

The Company may also use hedging derivatives to protect exchange of interest rates in different currencies. These hedging derivatives used as well as the risk being hedged are accounted for a cash flow model. Under this model, the gains and losses associated with the derivative instruments are deferred and recorded in "Accumulated other comprehensive income" until such time as the hedged transaction impacts earnings, with the exception of any hedge ineffectiveness, which is recorded directly in the statements of income.

m) Recently issued accounting pronouncements

· Intangibles - Goodwill and Other (Topic 350): When to perform step 2 of the goodwill impairment test for reporting units with zero or negative carrying amounts - (ASU 2010-28)

The ASU 2010-28 establishes when to perform the Step 2 of the Goodwill Impairment Test for Reporting Units with zero or negative carrying amounts. Under this new guidance an entity must consider whether it is more likely than not that goodwill impairment exists for each reporting unit with a zero or negative carrying amount. If it is considered that goodwill impairment exists, the second step of the Goodwill Impairment Test must be performed. The Company does not have goodwill recorded in reporting units with zero or negative carrying amounts.

n) Recently adopted accounting pronouncements

· Transfers and Servicing (ASC 860), Accounting for Transfers of Financial Assets (ASU 2009-16)

The FASB issued ASU 2009-16 in December 2009. This standard removes the concept of a Qualifying Special Purpose Entity ("QSPE") and the exception for QSPE consolidation and clarifies the requirements for financial asset transfers eligible for sale accounting. ASU 2009-16 was adopted on January 1, 2010, and did not impact the Company's results of operations, financial position or liquidity.

· Consolidation (ASC 810), Improvements to Financial Reporting by Enterprises Involved With Variable Interest Entities (ASU 2009-17)

The FASB issued ASU 2009-17 in December 2009. This standard became effective for the Company on January 1, 2010. ASU 2009-17 requires the enterprise to qualitatively assess if it is the primary beneficiary of a variable-interest entity ("VIE"), and, if so, the VIE must be consolidated. Additionally, this Statement requires continuous assessments of whether an enterprise is the primary beneficiary of a VIE. ASU 2009-17 was adopted on January 1, 2010, and did not impact the Company's results of operations, financial position or liquidity.

· Receivables (Topic 310): Disclosures about the Credit Quality of Financing Receivables and the Allowance for Credit Losses (ASU 2010-20)

The ASU 2010-20 enhance the disclosures required for financing receivables and allowances for credit losses under FASB Accounting Standards Codification 310, Receivables. Most of the existing disclosures have been amended to require information on a more disaggregated basis. ASU 2010-20 was adopted on December, 2010. Adoption of the standard did not change the Company's existing disclosures.

· Plan Accounting-Defined Contribution Pension Plans (Topic 962): Reporting Loans to Participants by Defined Contribution Pension Plans (a consensus of the FASB Emerging Issues Task Force) (ASU 2010-25)

The ASU 2010-25 requires participant loans to be classified as notes receivables from participants and measured at their unpaid principal balance, plus any accrued but unpaid interest. ASU 2010-25 was adopted on December, 2010, and did not impact the Company's results of operations, financial position or liquidity, other than disclosure.

o) Change in accounting estimates

The Company changed at the beginning of 2010, as a consequence of the periodic assessment of the expected useful lives of its assets, depreciation rates from thermoelectric power plants and facilities from Refining, Transportation and Marketing segment, based on reports prepared by independent appraisers. The changes were accounted for prospectively in accordance with ASC 250 (Accounting changes and error corrections) and the Company's results of operations were increased in US$352, net of taxes, in the year ended December 31, 2010.

The table below provides the previous and the current depreciation rates as a result of the assessment:

Estimated useful life	Previous	New (average)
Optic system equipment	7 years	20 years
Equipment and facilities of distribution	10 years	14 years
Industrial refining equipment and assemblies	10 years	20 years
Equipment and industrial plant fertilizer	10 years	22 years
Product storage tanks	10 years	26 years
Pipelines	10 years	31 years
Plataforms	16 years	27 years
Thermoelectric power plants	20 years	23 years
Vessels	20 years	25 years

p) IFRS adoption for local purposes

The Brazilian Corporation Law was amended in 2007 to permit Brazilian GAAP to converge with International Financial Reporting Standards, or "IFRS", as issued by the International Accounting Standards Board, or "IASB". The adoption of IFRS in Brazil is mandatory for the year ended December 31, 2010 and as per current tax legislation, the resulting adjustments in relation to the previous practice are not included in the determination of current income tax charge.

The Company chose to present its financial statements for local purposes for the first time in accordance with IFRS in the first quarter of 2010. The Company's financial statements prepared in accordance with U.S. GAAP were not affected by the adoption of IFRS other than dividends and profit sharing payable to our employees, which are based on the net income calculated under IFRS.

Financial Instruments [Abstract]

Note 20 - Financial Instruments [Text Block]

20. Financial Instruments

In the normal course of its business activities, the Company acquires various types of financial instruments.

a) Concentrations of credit risk

Substantial portions of the Company's assets including financial instruments are located in Brazil while substantially all of the Company's revenues and net income are generated in Brazil. The Company's financial instruments that are exposed to concentrations of credit risk consist primarily of its cash and cash equivalents, the Petroleum and Alcohol account, trade receivables and futures contracts.

The Company takes several measures to reduce its credit risk to acceptable levels. All cash and cash equivalents in Brazil are maintained with major banks. Time deposits in U.S. dollars are placed with creditworthy institutions in the United States. Additionally, all of the Company's available-for-sale securities and derivative contracts are either exchange traded or maintained with creditworthy financial institutions. The Company monitors its credit risk associated with trade receivables by routinely assessing the creditworthiness of its customers. At December 31, 2010 and December 31, 2009, the Company's trade receivables were primarily maintained with large distributors.

b) Fair value

Fair values are derived either from quoted market prices where available, or, in their absence, the present value of expected cash flows. Fair values reflect the cash that would have been either received or paid if the instruments were settled at year end in an arms length transaction between willing parties. Fair values of cash and cash equivalents, trade receivables, the Petroleum and Alcohol account, short-term debt and trade payables approximate their carrying values.

The fair values of other long-term receivables and payables do not differ materially from their carrying values.

The Company's debt including project financing obligations, resulting from Codification TOPIC 810 consolidation amounted to US$60,471, at December 31, 2010, and US$49,041 at December 31, 2009, and had estimated fair values of US$62,752 and US$48,804, respectively.

The fair value hierarchy for the Company's financial assets and liabilities accounted for at fair value on a recurring basis at December 31, 2010, was:

	As of December 31, 2010
	Level 1	Level 2	Level 3	Total
Assets
Marketable securities	18,557	-	-	18,557
Foreign exchange derivatives (Note 19)	-	117	-	117
Commodity derivatives (Note 19)	15	1	32	48
Total assets	18,572	118	32	18,722
Liabilities
Commodity derivatives (Note 19)	(40)	(2)	-	(42)
Total liabilities	(40)	(2)	-	(42)

The fair value hierarchy for the Company's non financial assets and liabilities accounted for at fair value on a non-recurring basis at December 31, 2010, was:

	As of December 31, 2010
	Level 1	Level 2	Level 3	Total
Assets
Long-lived assets held and used	-	-	122	122
Long-lived assets held for sale	-	32	-	32

In accordance with the provisions of ASC Topic 360, long-lived assets held and used with a carrying amount of US$465 were written down to their fair value of US$122, resulting in an impairment charge of US$352, before taxes, which was included in earnings for the period.

Long-lived assets held for sale with a carrying amount of US$82 were written down to their fair value of US$32, resulting in an impairment charge of US$50, before taxes, which was included in earnings for the period.

Fair value of long lived assets is estimated based on the present value of future cash flows, resulting from the company's best estimates. Inputs used to estimate fair value were: prices based on the last strategic plan published, production curves associated with existing products in the Company's portfolio, market operating costs and investments needed for carrying out the projects.

Supplementary Information on Oil and Gas Exploration and Production [Abstract]

Supplementary Information On Oil And Gas Exploration And Production [Text Block]

In accordance with Codification Topic 932 - Extractive Activities - Oil and Gas, this section provides supplemental information on oil and gas exploration and producing activities of the Company. The information included in items (i) through (iii) provides historical cost information pertaining to costs incurred in exploration, property acquisitions and development, capitalized costs and results of operations. The information included in items (iv) and (v) present information on Petrobras' estimated net proved reserve quantities, standardized measure of estimated discounted future net cash flows related to proved reserves, and changes in estimated discounted future net cash flows.

Beginning in 1995, the Federal Government of Brazil undertook a comprehensive reform of the country's oil and gas regulatory system. On November 9, 1995, the Brazilian Constitution was amended to authorize the Federal Government to contract with any state or privately-owned company to carry out the activities related to the upstream and downstream segments of the Brazilian oil and gas sector. This amendment eliminated Petrobras' effective monopoly. The amendment was implemented by the Oil Law, which liberated the fuel market in Brazil beginning January 1, 2002.

The Oil Law established a regulatory framework ending Petrobras' exclusive agency and enabling competition in all aspects of the oil and gas industry in Brazil. As provided in the Oil Law, Petrobras was granted the exclusive right for a period of 27 years to exploit the petroleum reserves in all fields where the Company had previously commenced production. However, the Oil Law established a procedural framework for Petrobras to claim exclusive exploratory (and, in case of success, development) rights for a period of up to three years with respect to areas where the Company could demonstrate that it had "established prospects". To perfect its claim to explore and develop these areas, the Company had to demonstrate that it had the requisite financial capacity to carry out these activities, alone or through financing or partnering arrangements.

The adoption of the SEC rules seeking to modernize the supplemental oil and gas disclosures and the FASB's issuance of the Accounting Standards Update n° 2010-03, "Oil and Gas Reserve Estimation and Disclosure", generated no material impact to the Company's consolidated financial statements other than additional disclosures as discussed in the Note 2(n).

The "International" geographic area includes activities in South America, which includes Argentina, Colombia, Ecuador, Peru, Uruguai and Venezuela; North America, which includes Mexico and the United States of America; Africa, which includes Angola, Lybia, Namibia, Nigeria, and Tanzania, and Others, which includes India, Iran, Portugal, Cuba, New Zealand, Australia and Turkey. The equity investments are composed of Venezuelan companies involved in exploration and production activities.

(iii) Results of operations for oil and gas producing activities

The Company's results of operations from oil and gas producing activities for the years ended December 31, 2010, 2009 and 2008 are shown in the following table. The Company transfers substantially all of its Brazilian crude oil and gas production to the Refining, Transportation & Marketing segment in Brazil. The prices calculated by the Company's model may not be indicative of the price the Company would have realized had this production been sold in an unregulated spot market. Additionally, the prices calculated by the Company's model may not be indicative of the future prices to be realized by the Company, Gas prices used are contracted prices to third parties.

Production costs are lifting costs incurred to operate and maintain productive wells and related equipment and facilities, including such costs as operating labor, materials, supplies, fuel consumed in operations and the costs of operating natural liquid gas plants. Production costs also include administrative expenses and depreciation and amortization of equipment associated with production activities.

Exploration expenses include the costs of geological and geophysical activities and non-productive exploratory wells. Depreciation and amortization expenses relate to assets employed in exploration and development activities. In accordance with Codification Topic 932 - Extractive Activities - Oil and Gas, income taxes are based on statutory tax rates, reflecting allowable deductions. Interest income and expense are excluded from the results reported in this table.

iv) Reserve quantities information

The Company's estimated net proved oil and gas reserves and changes thereto for the years 2010, 2009 and 2008 are shown in the following table. Proved reserves are estimated by the Company's reservoir engineers in accordance with the reserve definitions prescribed by the Securities and Exchange Commission.

Proved oil and gas reserves are those quantities of oil and gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations-prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. The project to extract the hydrocarbons must have commenced or the operator must be reasonably certain that it will commence the project within a reasonable time.

Developed oil and gas reserves are reserves of any category that can be expected to be recovered: (i) through existing wells with existing equipment and operating methods or in which the cost of the required equipment is relatively minor compared to the cost of a new well; and (ii) through installed extraction equipment and infrastructure operational at the time of the reserves estimate if the extraction is by means not involving a well.

In some cases, substantial new investments in additional wells and related facilities will be required to recover these proved reserves. Due to the inherent uncertainties and the limited nature of reservoir data, estimates of reserves are subject to change as additional information becomes available.

Bolivian proved reserves were not classified as such in 2009 due to the new Bolivian Constitution, which restrict the disclosure of estimated reserves for properties under its authority. The initial balance of Bolivian proved reserves for 2009 is adjusted under the line item "Revisions of previous estimates".

A summary of the annual changes in the proved reserves of oil is as follows (in millions of barrels):

(1) Includes reserves of 35.3 million barrels of oil and 276.3 billions of cubic feet of gas in 2010 (42.2 million barrels of oil and 312.00 billions of cubic feet of gas in 2009; and 71.5 million barrels of oil and 415.9 billions of cubic feet of gas in 2008) attributable to 32,76% minority interest in Petrobras Argentina, which is consolidated by Petrobras.

(v) Standardized measure of discounted future net cash flows relating to proved oil and gas quantities and changes therein

The standardized measure of discounted future net cash flows, related to the above proved oil and gas reserves, is calculated in accordance with the requirements of Codification Topic 932 - Extractive Activities - Oil and Gas. Estimated future cash inflows from production in Brazil and International segments are computed by applying the average price during the 12-month period prior to the ending date of the period covered by the report, determined as an unweighted arithmetic average of the first-day-of-the-month price for each month within such period, unless prices are defined by contractual arrangements, excluding escalations based upon future conditions based upon the Company's internal pricing methodology for oil and gas to year-end quantities of estimated net proved reserves. Future price changes are limited to those provided by contractual arrangements in existence at the end of each reporting year. Future development and production costs are those estimated future expenditures necessary to develop and produce year-end estimated proved reserves based on year-end cost indicators, assuming continuation of year-end economic conditions. Estimated future income taxes are calculated by applying appropriate year-end statutory tax rates. These rates reflect allowable deductions and are applied to estimated future pre-tax net cash flows, less the tax basis of related assets. Discounted future net cash flows are calculated using 10% midperiod discount factors. This discounting requires a year-by-year estimate of when the future expenditures will be incurred and when the reserves will be produced.

The arbitrary valuation prescribed under Codification Topic 932 - Extractive Activities - Oil and Gas requires assumptions as to the timing and amount of future development and production costs. The calculations are made as of December 31 each year and should not be relied upon as an indication of Petrobras' future cash flows or the value of its oil and gas reserves.

Debt of the electricity sector

The Company has receivables from the electricity sector related to the supplying of fuel to thermoelectric power stations located in the north region of Brazil. Part of the cost of supplying fuel to the thermoelectric power stations is supported by the funds of the Fuel Consumption Account (CCC) - Isolated Systems, the management of which is legally under the jurisdiction of Eletrobrás.

The Company also supplies fuel to Independent Power Producers (PIE), companies created for the purpose of producing power exclusively for Amazônia Distribuidora S. A. (ADESA), a direct subsidiary of Eletrobrás, whose payments for supplying fuel depend directly on the forwarding of funds from ADESA to these Independent Power Producers.

The balance of the receivables at December 31, 2010 was US$1,887 (US$ 1,153 at December 31, 2009), presented in non-current assets and classified as receivables from related parties of which US$1,424 was overdue.

Income taxes in Brazil comprise federal income tax and social contribution, which is an additional federal income tax. The statutory enacted tax rates for income tax and social contribution have been 25% and 9%, respectively for the years ended December 31, 2010, 2009 and 2008.

The Company's taxable income is substantially generated in Brazil and therefore subject to the Brazilian statutory tax rate.

The following table reconciles the tax calculated based upon the Brazilian statutory tax rate of 34% to the income taxes expenses recorded in the consolidated statements of income.

(1) On May 10, 2007, the Brazilian Federal Revenue Office recognized Petrobras' right to deduct certain tax incentives from income tax payable, covering the tax years from 2006 thru 2015. During the year ended December 31, 2010, Petrobras recognized a tax benefit in the amount of US$131 (US$167 on December 31, 2009 and US$219 on December 31, 2008) primarily related to these incentives in the Northeast, within the region covered by the Northeast Development Agency (ADENE), granting a 75% reduction in income tax payable, calculated on the profits of the exploration of the incentive activities, which have been accounted for under the flow through method.

The following table shows a breakdown between domestic and international income taxes benefits (expenses) attributable to income from continuing operations:

	Year ended December 31,
	2010	2009	2008
Brazil:
Current	(3,156)	(3,987)	(6,583)
Deferred	(2,887)	(932)	(2,463)
	(6,043)	(4,919)	(9,046)
International:
Current	(240)	(391)	(321)
Deferred	(73)	72	108
	(313)	(319)	(213)
Income taxes expenses	(6,356)	(5,238)	(9,259)

All the deferred tax assets and liabilities recorded are principally related to Brazil and there are no significant deferred tax assets and liabilities from international locations. There is no netting of deferred taxes between jurisdictions.

The major components of the deferred income taxes accounts in the consolidated balance sheets are as follows:

	As of December 31,
	2010	2009
Current assets	540	669
Valuation allowance	(5)	(8)
Current liabilities	(1)	(15)
Net current deferred tax assets	534	646
Non-current assets
Employees' postretirement benefits, net of Accumulated postretirements benefit reserves adjustments	1,458	879
Tax loss carryforwards	2,364	2,194
Other temporary differences, not significant individually	801	1,091
Valuation allowance	(1,803)	(1,691)
	2,820	2,473
Non-current liabilities
Capitalized exploration and development costs	(11,292)	(8,912)
Property, plant and equipment	(1,597)	(1,609)
Exchange variation	(1,390)	(995)

	(15,207)	(12,042)
Net non-current deferred tax liabilities	(12,387)	(9,569)
Non-current deferred tax assets	317	275
Non-current deferred tax liabilities	(12,704)	(9,844)
Net deferred tax liability	(11,853)	(8,923)

The Company has domestic accumulated tax loss carryforwards amounting to US$1,313 as of December 31, 2010, which are available to offset future taxable income, limited to 30% of taxable income in any individual year. These tax loss carryforwards can be carried forward indefinitely in Brazil. Management believes that for the tax benefits where valuation allowance is more likely than not that it will realize those tax benefits within ten years at the maximum.

The Company has foreign accumulated tax loss carryforwards amounting to US$5,684 as of December 31, 2010. Tax loss carryfowards exists in many international jurisdictions. Whereas some of these tax loss carryfowards do not have expiration date, others expire at various times from 2011 to 2030.

Valuation allowance has been established for certain credit loss carryfowards that reduce deferred tax to an amount that will, more likely than not, be realized. Annually management evaluates the realization of its deferred tax assets taking into consideration, among other elements, the level of historical taxable income, the projected future taxable income, tax-planning strategies, expiration dates of the tax loss carryforwards, and scheduled reversal of the existing temporary differences. The amount of the deferred tax asset considered realizable could, however, be reduced if estimates of future taxable income are reduced. The following presents the net change in the valuation allowance for the years ended December 31, 2010, 2009 and 2008:

	Year ended December 31,
	2010	2009	2008
Balance at January 1,	(1,699)	(1,614)	(667)
Additions	(146)	(185)	(1,071)
Reductions allocated to income tax expense	40	88	67
Cumulative translation adjustments	(3)	12	57
Balance at December 31,	(1,808)	(1,699)	(1,614)
Current valuation allowance	(5)	(8)	(5)
Long term valuation allowance	(1,803)	(1,691)	(1,609)

Valuation allowance additions of US$146 in 2010 and US$185 in 2009, primarily related to tax loss carryforwards from foreign operations and domestic thermoelectric power plants for which no tax benefit is expected to be realized in the foreseeable future.

The Company has not recognized a deferred tax liability of approximately US$449 for the undistributed earnings of its foreign operations that arose in 2010 and prior years as the Company considers these earnings to be indefinitely reinvested (US$280 in 2009). A deferred tax liability will be recognized when the Company no longer demonstrates that it plans to indefinitely reinvest the undistributed earnings. As of December 31, 2010, the undistributed earnings of these subsidiaries were approximately US$1,321 (US$823 as of December 31, 2009).

The Company has no unrecognized tax benefits relating to uncertain tax positions and accrued penalties and interest as of January 1, 2008, 2009 and 2010 and for the years ended December 31, 2008, 2009 and 2010. In addition, the Company does not expect that the amount of unrecognized tax benefits will increase significantly within the next 12 months.

The Company and its subsidiaries file tax returns in Brazilian jurisdiction and in many foreign jurisdictions for which is open for inspection depending on legislation applicable individually to them. In the case of the Brazilian and Argentinean tax positions, income tax returns remain subject to examination by the respective tax authorities for the years beginning in 2004.

Segment Reporting Disclosure [Abstract]

Note 21 - Segment Information [Text Block]

21. Segment Information

The following segment information has been prepared in accordance with Codification Topic 280 - Disclosure about Segments of an Enterprise and Related Information ("ASC 280"). The Company operates under the following segments, which are described as follows:

a) Exploration and Production: This covers the activities of exploration, production development and production of oil, NGL and natural gas in Brazil, for the purpose of supplying, as a priority, refineries in Brazil and, also, selling on the domestic and foreign markets the surplus petroleum and byproducts produced in their natural gas processing plants.

b) Refining, Transportation & Marketing: This consists of the refining, logistics, transport and trading activities of oil and oil products, exporting of ethanol, extraction and processing of schist, as well as holding interests in companies of the petrochemical sector in Brazil.

c) Gas & Power: It covers the activities of transport and trading of natural gas produced in Brazil or imported, transport and trading of LNG, generation and trading of electric power, as well as the corporate interests in transporters and distributors of natural gas and in thermoelectric power stations in Brazil, in addition to being responsible for the fertilizer business (migration of the fertilizer business from the Supply department to Gas and Energy, pursuant to a decision of the Board of Directors on September 21, 2009).

d) Distribution: It is responsible for the distribution of oil products, ethanol and compressed natural gas in Brazil, represented by the operations of Petrobras Distribuidora.

e) International: It covers the activities for exploration and production of oil and gas, supply, gas and energy, and distribution, carried out abroad in a number of countries in the Americas, Africa, Europe and Asia.

The items that cannot be attributed to the other departments, notably those linked to corporate financial management, the overheads related to central administration and other expenses, including actuarial expenses related to the pension and healthcare plans for retired employees and pensioners, are allocated in the corporate agencies group. The business dealings with biofuels, represented mainly by the operations of Petrobras Biocombustível are also included in this group.

The accounting information per business segment was prepared based on the assumption of controllability, for the purpose of attributing to the business departments only those items over which these departments have effective control.

In the computation of the results by business segment, transactions carried out with third parties and the transfers between the business departments are considered and they are valued by internal transfer prices defined between the departments using calculation methodologies based on market parameters.

(1) The segments "Refining, Transportation and Marketing" and "Gas and Power" were previously reported as "Supply" and "Gas and Energy", respectively, without representing changes in the factors used to identify the included activities, and in the amounts previously reported.

The main criteria used to record the results and assets by business segments are summarized as follows:

• Net operating revenues: these were considered to be the revenues from sales to third parties, plus revenues between the business segments, based on the internal transfer prices established by the areas;

• Costs and expenses includes the costs of products and services sold, calculated per business segment, based on the internal transfer price and the other operating costs of each segment, as well as operating expenses, based on the expenses actually incurred in each segment;

• Financial results are allocated to the corporate group;

• Assets: covers the assets relating to each segment.

The following presents the Company's assets by segment:

Note 16 - Shareholders Equity [Text Block]

16 Shareholders' Equity

a) Capital

The Company's subscribed and fully paid-in capital at December 31, 2010 consisted of 7,442,454,142 common shares and 5,602,042,788 preferred shares (5,073,347,344 common shares and 3,700,729,396 preferred shares at December 31, 2009). The preferred shares do not have any voting rights and are not convertible into common shares and vice-versa. Preferred shares have priority in the receipt of dividends and return of capital.

The Extraordinary General Meeting held on March 24, 2008, decided to effect a split of each Company's share into two, resulting: (a) in a free distribution of 1 (one) new share of the same type for each original share and based on the shareholding structure at April 25, 2008; (b) in a free distribution of 1 (one) new American Depository Shares (ADS) of the same type for each original ADS and based on the shareholding structure at April 25, 2008. At the same date, an amendment to article 4 of the Company's bylaws to cause capital be divided into 8,774,076,740 shares, of which 5,073,347,344 are common shares and 3,700,729,396 are preferred shares, with no nominal value, was approved. This amendment to the Company's bylaws is effective from April 25, 2008. The relation between the ADS and shares of each class remains of 2 (two) shares for one ADS.

b.1) Expenditures with the issuing of shares

The Global Offering direct costs in the amount of US$279, net of taxes, were recorded in shareholders' equity.

c) Appropriated retained earnings

Brazilian Law and the Company's bylaws require that certain appropriations be made from retained earnings to reserve accounts annually. The purpose and basis of appropriation to such reserves are as follows:

• Legal reserve

This reserve is a requirement for all Brazilian corporations and represents the annual appropriation of 5% of net income as stated in the statutory accounting records up to a limit of 20% of capital stock. The reserve may be used to increase capital or to compensate for losses, but may not be distributed as cash dividends.

• Statutory reserve

This reserve is provided through an amount equivalent to a minimum of 0.5% of subscribed and fully paid in capital at year-end. The reserve is used to fund the costs incurred with research and technological development programs. The accumulated balance of this reserve cannot exceed 5% of the capital stock, according to Article 55 of the Company's bylaws.

• Tax incentive reserve

This reserve consists of investments in tax incentives, arising from allocations of part of the Company's income tax. It relates to tax incentives in the Northeast, within the region covered by the Northeast Development Agency (ADENE), granting a 75% reduction in income tax payable, calculated on the profits of the exploration of the incentived activities. Up to December 31, 2010, this incentive amounted to US$131 (US$167 on December 31, 2009), which may only be utilized to offset losses or for a capital increase, as provided for in Article 545 of the Income Tax Regulations and has been accounted for under the flow through method.

On May 10, 2007, the Brazilian Federal Revenue Office recognized Petrobras' right to deduct this incentive from income tax payable, covering the tax years of 2006 until 2015.

• Undistributed earnings reserve

The destination of net income for the year ended December 31, 2010, includes retention of profits of US$12,914 with a US$12,172 amount, arising from net income for the year, and US$742 originating from the initial adoption of IFRS. This proposal is intended cover to partially meet the annual investment program established in the 2011 capital budget, to be decided in the General Shareholders' Meeting for 2011.

In addition, the preferred shareholders have priority in the receipt of an annual dividend of at least 3% of the book value of the shares or 5% of the paid-in capital in respect of the preferred shares as stated in the statutory accounting records. As of January 1, 1996, amounts attributed to shareholders as interest (see below) can be deducted from the minimum dividend computation. Dividends are paid in Brazilian reais. No withholding tax is payable on distributions of dividends made since January 1, 1996.The Company provides either for its minimum dividends or for the total interest on shareholders'equity where the tax benefit has been recognized as of December 31.

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2010

Accounting Policies [Abstract]

Basis of financial statements preparation

The accompanying consolidated financial statements of Petróleo Brasileiro S.A. - Petrobras (the Company) have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) and the rules and regulations of the Securities and Exchange Commission (SEC). U.S. GAAP differs in certain respects from International Financial Reporting Standards (IFRS), as issued by International Financial Reporting Standards Board (IASB) and applied by Petrobras in its statutory financial statements prepared in accordance with Brazilian Corporate Law and regulations promulgated by the Brazilian Securities and Exchange Commission (CVM). The Brazilian Corporation Law was amended in 2007 to permit Brazilian GAAP to converge with International Financial Reporting Standards, and Petrobras chose to present its financial statements for local purposes for the first time in accordance with IFRS in the first quarter of 2010 (see more details in Note 2 - item p).

The U.S. dollar amounts for the years presented have been translated from the Brazilian Real amounts in accordance Accounting Standard Codification - ASC Topic 830 - Foreign Currency Matters as applicable to entities operating in non-hyperinflationary economies. Transactions occurring in foreign currencies are first remeasured to the Brazilian Real and then translated to the U.S. dollar, with remeasurement gains and losses being recognized in the statements of income. While Petrobras has selected the U.S. Dollar as its reporting currency, the functional currency of Petrobras and all Brazilian subsidiaries is the Brazilian Real. The functional currency of Petrobras International Finance Company - PifCo and some subsidiaries and certain of the special purpose companies that operate in the international economic environment is the U.S. dollar, and the functional currency of Petrobras Argentina is the Argentine Peso.

The Company has translated all assets and liabilities into U.S. dollars at the current exchange rate (R$1.666 and R$1.741 to US$1.00 at December 31, 2010 and 2009, respectively), and all accounts in the statements of income and cash flows (including amounts relative to local currency indexation and exchange variances on assets and liabilities denominated in foreign currency) at the average rates prevailing during the year. The net translation gain in the amount of US$6,796 in 2010 (net translation gain in 2009 - US$22,589 and net translation loss in 2008 - US$20,001) resulting from this remeasurement process was excluded from income and presented as a cumulative translation adjustment ("CTA") within "Accumulated other comprehensive income" in the consolidated statements of changes in shareholders' equity.

Principles of consolidation

The consolidated financial statements include the accounts of the Company and all majority-owned subsidiaries in which (a) the Company directly or indirectly has either a majority of the equity of the subsidiary or otherwise has controlling financial interest, or (b) the Company has determined itself to be the primary beneficiary of a variable interest entity in accordance with Codification Topic 810-10-25 ("Variable Interest Entities"). All significant intercompany balances and transactions have been eliminated in consolidation.

(1) At December 31, 2010, the Company had amounts invested in the Petrobras Group's NonStandardized Credit Rights Investment Fund (Fundo de Investimento em Direitos Creditórios não-padronizados do Sistema Petrobras - "FIDC-NP"). This investment fund is predominantly intended for acquiring credit rights, performed and/or non-performed, in the Petrobras System companies, and aims to optimize the Company's cash management.

Cash and cash equivalents

Cash and cash equivalents consist of highly liquid investments that are readily convertible into cash and have an original maturity of three months or less at date of acquisition.

Marketable securities

Marketable securities have been classified by the Company as available-for-sale, held-to-maturity or trading based upon intended management's strategies with respect to such securities. The Company classifies and accounts for marketable securities under ASC Topic 320 - Investments:

· Trading securities, which are marked-to-market through current period earnings;

· Available-for-sale securities, which are marked-to-market through other comprehensive income;

· Held-to-maturity securities, which are recorded at amortized cost.

The interest and monetary restatement of the securities are recorded in the statement of income. There were no material transfers between categories.

Inventories

Inventories are stated as follows:

· Raw material comprises mainly the stocks of petroleum, which are stated at the average value of the importing or production costs, adjusted, when applicable, to their realization value;

· Oil products and fuel alcohol are stated, respectively, at average refining and purchase cost, adjusted when applicable to their realization value;

· Materials and supplies are stated at average purchase cost, not exceeding replacement value and imports in transit are stated at identified cost.

Investments in non-consolidated companies

The Company uses the equity method of accounting for all long-term investments for which it owns between 20% and 50% of the investee's outstanding voting stock or has the ability to exercise significant influence over operating and financial policies of the investee without controlling it. The equity method requires periodic adjustments to the investment account to recognize the Company's proportionate share in the investee's results, reduced by receipt of investee's dividends.

Property, plant and equipment

· Costs incurred in oil and gas producing activities

The costs incurred in connection with the exploration, development and production of oil and gas are recorded in accordance with the "successful efforts" method. This method requires that costs the Company incurs in connection with the drilling of developmental wells and facilities in proved reserve production areas and successful exploratory wells be capitalized. In addition, costs the Company incurs in connection with geological and geophysical activities are charged to the statements of income in the year incurred, and the costs relating to exploratory dry wells on unproved reserve properties are charged to the statements of income when determined as dry or uneconomical.

· Capitalized costs

The capitalized costs are depreciated based on the unit-of-production method using proved developed reserves. These reserves are estimated by the Company's geologists and petroleum engineers in accordance with SEC standards and are reviewed annually or more frequently when there are indications of significant changes.

· Property acquisition costs

Costs of acquiring developed or undeveloped leaseholds including lease bonus, brokerage, and other fees are capitalized. The costs of undeveloped properties that become productive are transferred to a producing property account.

· Exploratory costs

Exploratory wells that find oil and gas in an area requiring a major capital expenditure before production begins are evaluated annually to assure that commercial quantities of reserves have been found or that additional exploration work is underway or planned. Exploratory costs related to areas where commercial quantities have been found are capitalized, and exploratory costs where additional work is underway or planned continue to be capitalized pending final evaluation. Exploratory well costs not meeting either of these tests are charged to expense. All other exploratory costs (including geological and geophysical costs) are expensed as incurred. Exploratory dry holes are expensed.

· Development costs

Costs of development wells including wells, platforms, well equipment and attendant production facilities are capitalized.

· Production costs

Costs incurred with producing wells are recorded as inventories and are expensed when the products are sold.

· Abandonment costs

The Company makes its annual reviews and revision of its estimated costs associated with well abandonment and the demobilization of oil and gas production areas, considering new information about date of expected abandonment and revised cost estimates to abandon. The changes in estimated asset retirement obligation are principally related to the commercial declaration of new fields, certain changes in cost estimates, and revisions to abandonment information provided for non-operated joint ventures, considering the useful economic life of the fields and the expected cash flows, to present value, at a rate of interest free of risks, adjusted by the Petrobras risk.

· Depreciation, depletion and amortization

Depreciation, depletion and amortization of leasehold costs of producing properties are recorded using the unit-of-production method applied on a field by field basis as a ratio of proved developed reserves. Production platform under capital lease which is not tied to the respective wells, are depreciated on a straight-line basis over the estimated useful lives of the platforms. Depreciation, depletion and amortization of all other capitalized costs (both tangible and intangible) of proved oil and gas producing properties is recorded using the unit-of-production method applied on a field by field basis as a ratio of proved developed reserves produced. The straight-line method is used for assets with a useful life shorter than the life of the field.

Other plant and equipment are depreciated on a straight line basis, based on the following estimated useful lives:

Class of assets	Useful life
	average weighted
Buildings and improvements	25 years (25-40 years)
Equipment and other assets	20 years (3-31 years)

· Impairment

In accordance with Codification Topic 360-10, management reviews long-lived assets, primarily property, plant and equipment to be used in the business and capitalized costs relating to oil and gas producing activities, whenever events or changes in circumstances indicate that the carrying value of an asset or group of assets may not be recoverable on the bases of undiscounted future cash flows. The reviews are carried out at the lowest level of assets to which the Company is able to attribute identifiable future cash flows. The net book value of the underlying assets is adjusted to their fair value using a discounted future cash flows model, if the sum of the expected undiscounted future cash flows is less than the book value.

The main assumptions of cash flows are: prices based on last strategic plan presented, production curves associated to existent projects comprising the Company's portfolio, operating market costs and investments needed for projects conclusion.

· Maintenance and repairs

Maintenance and repairs, that do not embody significant improvements, are expensed as incurred, as well as planned major maintenances. Expenditures which appreciably extend the life, increase the capacity, or improve the efficiency of existing property are capitalized.

· Capitalized interest

Interest is capitalized in accordance with Codification Topic 835-20 - Capitalization of Interest Cost. Interest is capitalized on specific projects when a construction process involves considerable time and involves major capital expenditures. Capitalized interest is allocated to property, plant and equipment and amortized over the estimated useful lives or unit-of-production method of the related assets. Interest is capitalized at the Company's weighted average cost of borrowings.

Revenues, costs and expenses

Revenue from sales of crude oil and oil products, petrochemical products, natural gas and other related products is recognized when title passes to the customer, because at that time the amount can be reasonably measured, collectibility is reasonably assured, persuasive evidence of an arrangement exists, the seller's price to the buyer is fixed or determinable and the significant risks and rewards of ownership have been transferred. Title is transferred to the customer when delivery occurs pursuant to the terms of the sales contracts. Revenues from the production of natural gas properties in which Petrobras has an interest with other producers are recognized based on the actual volumes sold during the period. Subsequent adjustments to revenues based on production sharing agreements or volumetric delivery differences are not significant. Costs and expenses are accounted for on an accrual basis. Purchases and sales of inventory with the same counterparty (buy/sell arrangements) are combined and recorded on a net basis and reported in "Cost of Sales" on the Consolidated Statements of Income.

Income taxes

The Company accounts for income taxes in accordance with Codification Topic 740 -Accounting for Income, which requires an asset and liability approach to recording current and deferred taxes. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to the differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

The Company records the tax benefit of all net operating losses as a deferred tax asset and recognizes a valuation allowance for any part of this benefit which management believes will not be recovered against future taxable income using a "more likely than not" criterion.

In accordance with Codification Topic 740-10, the Company recognizes the effect of an income tax position only if that position is more likely that not of being sustained upon examination, based on technical merits of the position. A recognized income tax position is measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgement occurs. The Company records interests and penalties related to unrecognized tax benefits in "Other expenses".

Employees' postretirement benefits

The Company sponsors a contributory defined-benefit pension plan covering substantially all of its employees, which is accounted and disclosured for by the Company in accordance with Codification Topic 715 - Compensation-Retirement Benefits.

In addition, the Company provides certain health care benefits for retired employees and their dependents. The cost of such benefits is recognized in accordance with Codification Topic 715 - Compensation-Retirement Benefits.

The Company also contributes to the Brazilian pension and government sponsored pensions of international subsidiaries, social security and redundancy plans at rates based on payroll, and such contributions are expensed as incurred. Further indemnities may be payable upon involuntary severance of employees but, based on current operating plans, management does not believe that any amounts payable under this plan will be significant.

Earnings per share

Earnings per share are computed using the two-class method, which is an earnings allocation formula that determines earnings per share for both preferred shares, which are participating securities and common shares as if all of the net income for each year had been distributed in accordance with a predetermined formula described in Note 16(f).

Accounting for derivatives and hedging activities

The Company applies Codification Topic 815 - Derivatives and Hedging, together with its amendments and interpretations, referred to collectively herein as "ASC 815". These rules require that all derivative instruments be recorded in the balance sheet of the Company as either an asset or a liability and measured at fair value. ASC 815 requires that changes in the derivative's fair value be recognized in the income statement unless specific hedge accounting criteria are met; and the Company designates. For derivatives designated as accounting hedges, fair value adjustments are recorded either in the income statements or "Accumulated other comprehensive income", a component of shareholders' equity, depending upon the type of accounting hedge and the degree of hedge effectiveness.

The Company uses derivative financial instruments, not designated as hedge accounting, to mitigate the risk of unfavorable price movements for crude oil purchases. These instruments are marked-to-market with the associated gains or losses recognized as "Financial income" or "Financial expenses".

The Company may also use non-hedging derivatives to mitigate the risk of unfavorable exchange-rate movements on its foreign currency-denominated funding. Gains and losses from changes in the fair value of these contracts are recognized as "Financial income" or "Financial expenses".

The Company may also use hedging derivatives to protect exchange of interest rates in different currencies. These hedging derivatives used as well as the risk being hedged are accounted for a cash flow model. Under this model, the gains and losses associated with the derivative instruments are deferred and recorded in "Accumulated other comprehensive income" until such time as the hedged transaction impacts earnings, with the exception of any hedge ineffectiveness, which is recorded directly in the statements of income.

Recently issued accounting pronouncements

· Intangibles - Goodwill and Other (Topic 350): When to perform step 2 of the goodwill impairment test for reporting units with zero or negative carrying amounts - (ASU 2010-28)

The ASU 2010-28 establishes when to perform the Step 2 of the Goodwill Impairment Test for Reporting Units with zero or negative carrying amounts. Under this new guidance an entity must consider whether it is more likely than not that goodwill impairment exists for each reporting unit with a zero or negative carrying amount. If it is considered that goodwill impairment exists, the second step of the Goodwill Impairment Test must be performed. The Company does not have goodwill recorded in reporting units with zero or negative carrying amounts.

Recently adopted accounting pronouncements

· Transfers and Servicing (ASC 860), Accounting for Transfers of Financial Assets (ASU 2009-16) The FASB issued ASU 2009-16 in December 2009.

ASU 2009-16 was adopted on January 1, 2010, and did not impact the Company's results of operations, financial position or liquidity. · Consolidation (ASC 810), Improvements to Financial Reporting by Enterprises Involved With Variable Interest Entities (ASU 2009-17) The FASB issued ASU 2009-17 in December 2009. This standard became effective for the Company on January 1, 2010. ASU 2009-17 requires the enterprise to qualitatively assess if it is the primary beneficiary of a variable-interest entity ("VIE"), and, if so, the VIE must be consolidated. Additionally, this Statement requires continuous assessments of whether an enterprise is the primary beneficiary of a VIE. ASU 2009-17 was adopted on January 1, 2010, and did not impact the Company's results of operations, financial position or liquidity. · Receivables (Topic 310): Disclosures about the Credit Quality of Financing Receivables and the Allowance for Credit Losses (ASU 2010-20) The ASU 2010-20 enhance the disclosures required for financing receivables and allowances for credit losses under FASB Accounting Standards Codification 310, Receivables. Most of the existing disclosures have been amended to require information on a more disaggregated basis. ASU 2010-20 was adopted on December, 2010. Adoption of the standard did not change the Company's existing disclosures. · Plan Accounting-Defined Contribution Pension Plans (Topic 962): Reporting Loans to Participants by Defined Contribution Pension Plans (a consensus of the FASB Emerging Issues Task Force) (ASU 2010-25) The ASU 2010-25 requires participant loans to be classified as notes receivables from participants and measured at their unpaid principal balance, plus any accrued but unpaid interest. ASU 2010-25 was adopted on December, 2010, and did not impact the Company's results of operations, financial position or liquidity, other than disclosure.

Change in accounting estimates

The Company changed at the beginning of 2010, as a consequence of the periodic assessment of the expected useful lives of its assets, depreciation rates from thermoelectric power plants and facilities from Refining, Transportation and Marketing segment, based on reports prepared by independent appraisers. The changes were accounted for prospectively in accordance with ASC 250 (Accounting changes and error corrections) and the Company's results of operations were increased in US$352, net of taxes, in the year ended December 31, 2010.

The table below provides the previous and the current depreciation rates as a result of the assessment:

Estimated useful life	Previous	New (average)
Optic system equipment	7 years	20 years
Equipment and facilities of distribution	10 years	14 years
Industrial refining equipment and assemblies	10 years	20 years
Equipment and industrial plant fertilizer	10 years	22 years
Product storage tanks	10 years	26 years
Pipelines	10 years	31 years
Plataforms	16 years	27 years
Thermoelectric power plants	20 years	23 years
Vessels	20 years	25 years

IFRS adoption for local purposes

The Brazilian Corporation Law was amended in 2007 to permit Brazilian GAAP to converge with International Financial Reporting Standards, or "IFRS", as issued by the International Accounting Standards Board, or "IASB". The adoption of IFRS in Brazil is mandatory for the year ended December 31, 2010 and as per current tax legislation, the resulting adjustments in relation to the previous practice are not included in the determination of current income tax charge.

The Company chose to present its financial statements for local purposes for the first time in accordance with IFRS in the first quarter of 2010. The Company's financial statements prepared in accordance with U.S. GAAP were not affected by the adoption of IFRS other than dividends and profit sharing payable to our employees, which are based on the net income calculated under IFRS.

(**) On August 18, 2010 SPE Transportadora Urucu Manaus (TUM) was taken over by Transportadora Associada de Gás (TAG).

e) Guarantees and covenants

Financial institutions abroad do not require guarantees from the Company. The financing granted by BNDES - National Bank for Social and Economic Development is guaranteed by a lien on the assets being financed (carbon steel pipes for the Bolivia-Brazil gas pipeline and vessels).

On account of a guarantee agreement issued by the Federal Goverment in favor of Multilateral Loan Agencies, motivated by financings funded by TBG, counter guarantee agreements were signed, which had as signatories the Federal Government, TBG, Petrobras, Petroquisa and Banco do Brasil S.A., where TBG undertakes to entail its revenues to the order of the Brazilian Treasuary until the settlement of the obligations guaranteed by the Federal Government. This debt had an outstanding balance of US$213 and US$253 at December 31, 2010 and 2009, respectively.

In guarantee of the debentures issued, REFAP has a short-term investment account (bank deposits indexed to credit operations), tied to variations of the Interbank Deposit Certificate -CDI. REFAP has to maintain three times the value of the sum of the last installment due of the amortization of the principal and related charges.

At December 31, 2010 and 2009, Gaspetro had secured certain debentures issued to finance the purchase of the transportation rights in the Bolivia/Brazil pipeline with 3,000 shares of its interest in TBG, a subsidiary of Gaspetro responsible for the operation of the pipeline.

The Company's debt agreements contain affirmative covenants regarding, among other things provision of information; financial reporting; conduct of business; maintenance of corporate existence; maintenance of government approvals; compliance with applicable laws; maintenance of books and records; maintenance of insurance; payment of taxes and claims; and notice of certain events. The Company's debt agreements also contain negative covenants, including: without limitation; limitations on the incurrence of indebtedness; limitations on the incurrence of liens; limitations on transactions with affiliates; limitations on the disposition of assets; limitation on consolidations, mergers, sales and/or conveyances; negative pledge restrictions; change in ownership limitations; ranking; use of proceeds limitations; and required receivables coverages. Petrobras' management affirms that the Company is in compliance with the covenants within debt agreements.
