Report of Independent Registered
Public Accounting Firm

To the Board of Directors and Shareholders

We have reviewed the accompanying condensed consolidated balance sheet of Petróleo Brasileiro S.A. Petrobras and its subsidiaries as of March 31, 2012, and the related condensed consolidated statements of income, of cash flows, of comprehensive income and of shareholders equity for the three-month period ended March 31, 2012. This interim financial information is the responsibility of the Company s management.

We conducted our review in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should be made to the accompanying condensed consolidated interim financial information for it to be in conformity International Financial Reporting Standards as issued by the International Accounting Standards Board.

The financial statements of the Company as of and for the year ended December 31, 2011 and the financial information as of and for the quarter ended March 31, 2011 were audited and reviewed, respectively, by other auditors who issued unqualified opinion and review reports dated February 9, 2012 and May 13, 2011, respectively.

29.3 Joint Ventures Frade field

In November 2011, there was an oil spillage in the Frade field, located in the Campos basin, which is operated by Chevron Brasil. The federal public prosecutor is conducting an investigation and has initiated a process claiming US$ 11 billion in damages against Chevron Brazil, Chevron Latin America Marketing LLC and Transocean Brasil Ltda., where the latter was operator of the platform at the time of the spillage.

In April 2012, a new public civil suit was filed by the Federal Public Attorney s Office against Chevron and Transocean, due to droplets of oil identified in underwater images within the Frade field. In this suit the Federal Public Attorney s Office intends to condemn the defendants to a further US$ 11 billion as compensation for damages to the community.

The assessment by our lawyers is that the amounts claimed are not reasonable and are disproportionately high in relation to the extent of the damages caused. In the second suit, as the oil was not identified on the surface, it is not even possible to conceive of the existence of any actual damage to the community. .

Petrobras holds a 30% interest in the Frade consortium. Although it is not a party to the processes, because of its equity interest Petrobras may be contractually obliged to pay 30% of the total contingencies related to the Frade field. In the event Chevron is held legally responsible, Petrobras may be contractually subject to the payment of up to 30% of the costs referring to the compensations.

29.4 Contingencies assets

29.4.1 Recovery of maintenance costs Barracuda & Caratinga

In 2006, Petrobras, as representant of Barracuda & Caratinga Leasing Company B.V. (BCLC), filed to an arbitration abroad against Kellogg, Brown, Root, LLC (KBR), to obtain indemnifications for maintenance costs incurred on flexible lines of the Barracuda and Caratinga field, during the period covered by a contractual guarantee.

On September 21, 2011, the arbitration Court decided in favor of BCLC, definitively, condemning KBR to indemnify US$ 186 plus arbitration costs incurred by Petrobras and legal fees. After the final decision, Petrobras recognized the amount of US$ 186 in non-current assets.

29.4.2 Recovery of PIS and COFINS

Petrobras and its subsidiaries filed a civil suit against the Federal Government claiming to recover, through offsetting, amounts paid as taxes on financial revenue and exchange gains (PIS) in the period between February 1999 and November 2002 and COFINS between February 1999 and January 2004, taking into consideration that paragraph 1 of article 3 of Law 9,718/98 is unconstitutional.

On November 9, 2005, the Federal Supreme Court considered paragraph 1 of article 3 of Law 9,718/98 is unconstitutional.

On November 18, 2010, the Superior Court of Justice upheld the claim by Petrobras, filed in 2006 to recover the COFINS for the period from January 2003 to January 2004. After the final decision, Petrobras recognized the amount of US$ 273 as recoverable taxes in non current assets.

On March 31, 2012, the Company had US$ 1,402 related to these suits that are not yet recognized in the financial statement due to the pending final favorable decision.

29.4.3 Legal proceeding in the United States - P-19 e P-31

In 2002, Brasoil and Petrobras won, in the first instance, before the U.S. Justice, related actions filed by the insurance companies United States Fidelity & Guaranty Company and American Home Assurance Company, where, through a final decision confirmed by the Federal Court of the Southern District of New York, the right was recognized to receipt by Brasoil and Petrobras for losses and damages, plus interest and reimbursement of legal expenses on the date of receipt, referring to the performance bond of platforms P-19 and P-31. The amount of the indemnification is approximately US$ 290.

On July 21, 2006, the US court handed down an executive decision, conditioning the payment of the amounts owed to Brasoil to the permanent closing of legal proceedings involving identical claims in progress before the Brazilian courts, which the parties proceeded to do.

30. Guarantees for concession agreements for oil exploration

Petrobras gave guarantees to the Agência Nacional do Petróleo, Gás Natural e Biocombustíveis (ANP) in the total amount of US$ 3,432 for the Minimum Exploration Programs established in the concession agreements for exploration areas, with US$ 3,108, net of commitments already undertaken, remaining in force. Of this amount, US$ 1,855 corresponds to a lien on the oil from previously identified fields already in production, and US$ 1,253 refers to bank guarantees.

31. Risk management and derivative instruments

The Company is exposed to a series of financial risks arising from its operations. These risks include market risk related to the price of oil and oil products, exchange and interest rates, credit risk and liquidity risk.

31.1 Management of risks

The Petrobras risk management policy aims at contributing towards an appropriate equilibrium between its objectives for growth and return and its risk exposure level, 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 achieve its strategic goals.

The Executive Board, responsible for the management of Petrobras' risks, set up the Financial Integration Committee to periodically assess and establish guidelines for measuring, monitoring, and managing the risks, and to support its decisions. This Committee is permanently composed of all the executive managers of the financial department, and the executive managers of the business departments are convened for discussions of specific themes.

31.2 Market risk

31.2.1 Risk management of prices of oil and oil products

Petrobras maintains, as a preference, exposure to the prices cycle, not using derivatives for hedging the purchases and sales that aim at attending the Company's operational requirements.

Operations with derivatives are limited to hedging the expected results from transactions carried out abroad, which are usually short-term, accompanying the terms of commercial operations.

The main parameters used in risk management, for changes in Petrobras' prices of oil and oil products, in the transactions carried out abroad, are: operating cash flow at risk (CFAR), Value at Risk (VAR) and Stop Loss.

b) Sensitivity analysis of derivatives of oil and oil products

The probable scenario is the fair value at March 31, 2012. The possible and remote scenarios consider a deterioration in the prices in the risk variable of 25% and 50%, respectively, with respect to the same date.

Market derivatives for oil and oil products	Risk	Probable scenario in March 31, 2012	Possible scenario (Δ of 25%)	Remote scenario (Δ of 50%)

c) Embedded derivatives sale of ethanol

The Company entered into a sales agreement of ethanol a price formula set in the time of signing the contract. The selling price is based on the prices of ethanol and of naphtha.

Considering that the quotation for naphtha does not have a strict relationship with the market cost or value of ethanol, the portion referring to the derivative instrument was separated from the main agreement and recognized at fair value (level 3), and classified as financial income. The Company determined the fair value of this agreement based on the difference between the spreads for naphtha and ethanol.

The notional and fair values and the sensitivity analysis of the swap are presented below:

				Sensitivity analysis
		Fair Value
Forward Contract	Notional value (in thousand of m³)	March 31, 2012	December 31, 2011	Risk	Probable scenario in March 31, 2012	Possible scenario (Δ of 25%)	Remote scenario (Δ of 50%)

Petróleo Brasileiro S.A. - Petrobras and subsidiaries

Consolidated notes to the financial statements (Continued)

(Expressed in millions of Dollars, except when specifically indicated)

The Company determined the fair value of this contract based on practices used on the market, where the difference between the spreads for naphtha and ethanol is calculated. The selling price of the ethanol in the agreement refers to the Brazilian market (ESALQ). The values of the parameters used in the calculation were obtained from market price quotations 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.

31.2.2 Exchange 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 that reference asset and liabilities positions.

As regards exchange risk management, Petrobras seeks to identify and handle them in an integrated manner, and treat them 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.

a) Main transactions and future commitments hedged by derivative operations

Cross Currency Swap

Yen vs. Dollar

The Company contracted a cross currency swap, aimed at fixing in dollars the Company's bonds issued in yens. The Company does not intend to settle these contracts before the end of term.

For this relation between the derivative and the loan, qualified as cash flow hedge, the hedge accounting was adopted.

Changes in fair value, to the extent the hedge is effective, which is tested quarterly, are reported in accumulated other comprehensive income until the results of the hedged item occurs.

¹ Financing in local currency parameterized to the variation of the dollar.

Currency risks arise from the devaluation of the Real against the foreign currencies.

Sensitivity analysis of net debt alone does not represent the Company's net exposure to currency risk. Considering the equilibrium of liabilities, assets, revenues and future commitments in foreign currency, the economic impact of possible foreign exchange fluctuations does not compromise the Company s liquidity since a large portion of its debt is due at the long-term.

31.2.3 Interest rate risk management

Petrobras is subject mainly to fluctuations of the LIBOR, in the financing expressed in foreign currency, and to the long-term interest rate, published by the Central Bank, in the financing expressed in Reais. An increase in the rates negatively impacts Petrobras's financial expenses and financial position.

Petrobras considers that the exposure to interest rate fluctuations will not have a material impact, and so, preferably, it does not use derivative financial instruments to manage this type of risk; except for specific situations presented by companies of the Petrobras' system.

a) Main transactions and future commitments hedged by operations with derivatives

Swap contracts

Floating interest rate ( Libor USD) vs. Fixed rate (USD)

The Company contracted an interest rate swap in order to transform financing tied to a floating rate into a fixed rate in order to eliminate the mismatch between the cash flows of assets and liabilities of an investment project. The Company does not intend to settle the operation before its

31.3 Credit risk

Petrobras is exposed to the credit risk of clients and financial institutions, resulting from its commercial operations and its cash management. These risks consist of the possibility of non-receipt of sales made and amounts invested, deposited or guaranteed by financial institutions.

Credit risk management in Petrobras is part of financial risk management, which is performed by the Company s officers, under a policy of corporate risk management. The Credit Commissions are, each, composed of Executive Manager for Finances and the Executive Manager for the commercial department.

The purpose of the Credit Commissions is to analyze questions connected with credit management, not only with respect to granting credit but also with respect to its management; to encourage integration between the units that compose them; and to identify recommendations to be applied in the units involved or to be submitted to the appreciation of higher jurisdictions.

The credit risk management policy is part of the Company s global risk management policy and aims at reconciling the need for minimizing exposure to credit risk and maximizing the result of

sales and financial operations, through an efficient credit analysis, concession and management process.

In its management of credit risks, Petrobras uses quantitative and qualitative parameters that are appropriate for each of the market segments in which it operates.

The Company s commercial credit portfolio, is very diversified and the credits granted are divided between clients on the Brazilian domestic market and foreign markets.

Loans to financial institutions are distributed among the major international banks considered by the international risk classifiers as Investment Grade and the most important Brazilian banks.

The maximum exposure to credit risk is represented mainly by the balance of accounts receivable and derivative transactions outstanding.

31.4 Liquidity risk

The Company's liquidity risk is represented by the possibility of a shortage of funds, cash or another financial asset in order to settle its obligations on the established dates.

The policy on liquidity risk management adopted by the Company provides for the continued lengthening of the maturity of its debt, exploring the financing capacity of the domestic market and developing a strong presence in the international capital market by broadening the investor s base in fixed income.

Petrobras finances the working capital through the centralization of the System s cash and assuming short-term debt that are usually related to the flow of trade, as export credit notes and advances on exchange contracts. Investments in non-current assets are financed through long-term debt as issuing bonds in the international market, credit bureaus, financing and pre-payment of exports, development banks in Brazil and abroad, and lines of credit with national and international commercial banks.
