PETROBRAS ANNOUNCES RESULTS FOR THE SECOND QUARTER OF 2009

(Rio de Janeiro – August 14, 2009) – PETRÓLEO BRASILEIRO S.A. – Petrobras announces today its consolidated results expressed in millions of Brazilian Reais, in accordance with generally accepted accounting practices in Brazil (BR GAAP) and the norms issued by the CVM (Brazilian Securities and Exchange Commission). In order to facilitate comparisons, the accounting data for the periods ended in 2008 have been adjusted in line with the accounting practices determined by Law 11,638/07 and Presidential Decree 449/08, converted in Law 11.941/09.

Consolidated net income in the 2Q-2009 totaled R$ 7,734 million, 33% up on the previous quarter, primarily due to increased production, the recovery of oil prices and their impact on exports, and the reduction in operating expenses. Operating cash flow, measured by EBITDA, came to R$ 17,513 million and the operating margin widened by 7% over the previous quarter.

Consolidated net income in the 1H-2009 fell 20% year-on-year, chiefly due to the 53% reduction in the average Brent crude price, which dropped from US$ 109 in the 1H-2008 to US$ 52, and the decline in international oil products prices. The negative financial result, generated by higher financing volume, commercial hedge operations and the impact of the exchange variation on assets abroad also contributed to this result. However, these effects were partially offset by the tax benefit from the provisions for Interest on Own Capital in June/2009.

On the other hand operating cash flow (EBITDA) remained much closer to 2008 levels, totaling R$ 30,936 million, 6% down on the R$ 32,814 million recorded in the 1H-2008.

Total second-quarter oil and gas production (Brazil and abroad) increased by 2% over the 1Q-2009 and by 6% year-on-year in the 1H-2009. Increased output from the P-52 and P-54 platforms (Roncador), coupled with the startup of P-53 (Marlim Leste) and P-51 (Marlim Sul), more than offset the natural decline of the mature fields.

First-half investments came to R$ 32,709 million, mostly allocated to expanding future oil and gas production capacity, the Company’s investment priority, which absorbed 45% of the total. In percentage growth terms, the leaders were the Supply, Gas and Energy, and International segments, where the respective main allocations were refinery investments in Brazil, gas pipeline network in Brazil and the distribution businesses in Chile.

PETROBRAS SYSTEM

Statement by the CEO, José Sergio Gabrielli de Azevedo

Dear shareholders and investors,

Our results for the first half of 2009 were excellent, despite the substantial fall in oil prices. We generated more than R$ 30 billion of operating cash flow (measured by EBITDA) and recorded net income of R$ 13.6 billion.

The positive results in all our operating segments reflect the benefits of being an integrated company. The Supply area reported net income of more than R$ 10 billion in the first half of the year, largely offsetting reduced income from lower prices in our Brazilian Exploration and Production segment. The Gas and Energy area recorded positive net income despite weak markets for electric generation and natural gas, as added flexibility from completed infrastructure increase income. Our Distribution segment recorded gains in market share and higher margins, which supported their net income despite reduced demand in Brazil.

The success of our operations and the positive outlook has been translated into gains for our investors and shareholders. The Company’s market value increased by 60% during the first six months of the year, while the AmexOil, an index which includes all major oil companies, fell by 2% in the same period.

Our oil and gas production continues to grow. We have installed 525,000 bpd of production capacity since the end of 2008, with the installations of P-51, P-53 and FPSO Cidade de Niterói platforms, as well as the start-up of operations in the Parque das Conchas and Frade fields. These new units will serve as the base for our continued growth in production. Year over year oil and NGL production increased 7% in the first semester, a result unmatched by any other major oil company.

We continue to find oil as a result of our exploration. In April we declared the Piracucá Field off the coast of São Paulo commercially viable, with an estimated in situ volume of 550 million barrels of oil equivalent. In May we disclosed the existence of gas and condensates in the Panoramix well, in shallow waters also off the São Paulo coast.

There were also new pre-salt discoveries from the Corcovado-1 well, in the Santos Basin pre-salt layer, and the Iguaçu well, located in the Carioca appraisal area of Block BM-S-9 at a depth of more than two thousand meters.

Another important milestone was the start-up of the Tupi Extended Well Test on May 1. The EWT is designed to study various aspects of this new frontier, such as reservoir behavior, fluid movement and drainage, and well geometry. Although briefly interrupted at the beginning of July for equipment repairs, results have been as expected and will prove invaluable when planning the area’s development.

Internationally, we concluded the acquisition of distribution assets in Chile, ensuring an important presence in that market. The acquisition of 100% of Petrobras Energía Perú was also approved. Finally, the Company acquired a 50% interest in an important exploration block off Namibia as part of its ongoing strategy of deploying its know-how and technology in exciting new frontier area in deep and ultra-deep waters.

Despite difficult credit markets, the company’s investment-grade status and market credibility allowed us to issue in February US$ 1.5 billion in Global Notes maturing in 2019. We reopened this issue in July, raising an additional US$ 1.25 billion, at 150 basis points below February’s yield. Demand exceeded supply by five times in the reopening. Our substantial resource base and our ongoing investment plan enabled us to finalize terms with the China Development Bank for a financing of US$ 10 billion for 10 years, as well as a US$ 2 billion financing line from the U.S. EximBank. In July, we closed our financing with the BNDES for R$ 25 billion.

We continue to invest in accordance with our opportunities and our cash flow. Our first-half investment program totaled more than R$ 32 billion, 57% up year-on-year, the largest share going to Exploration & Production in Brazil to grow production.

Despite the uncertainties still surrounding the global economy, the company continues to demonstrate its capacity to overcome challenges and achieve its long-term targets. We are proud to say that in an increasingly dynamic and competitive environment, our achievements in the first half of 2009 demonstrate that we are on the right path.

PETROBRAS SYSTEM		Financial Performance

	A R$ 1,405 million increase in operating expenses, notably:

	•	Exploration costs (R$ 508 million), due to the increase in the write-off of dry and economically unviable wells (R$ 114 million) and increased geological and geophysical costs (R$ 357 million) in Brazil, in turn caused by the intensification of the Company’s investment program;

	•	General and administrative expenses (R$ 417 million), due to the rise in personnel costs (R$ 127 million) as a result of the increase in the workforce, the 2008/09 collective bargaining agreement and salary-level advancements and promotions in 2008, higher third-party service costs (R$ 97 million), especially expenses related to data processing and the incorporation of new companies (R$ 43 million); and the exchange impact on the conversion of expenses from foreign subsidiaries (R$ 121 million);

	•	Other operating expenses (R$ 285 million), due to the recognition of losses from the depreciation of commodities (R$ 454 million) due to the change in the commodity price level, and expenses from non- operational equipment (R$ 161 million) from the docking of drills that will be used in maritime fields, offset by the decline in regulatory and contractual fines that occurred in 2008 (R$ 282 million), resulting from failures in gas supplies to thermal plants, and lower expenses from institutional relations and cultural projects (R$ 133 million);

	•	Selling expenses (R$ 250 million), due to higher export and trading volumes, which pushed up ship chartering expenses, and expenses from chartering in the cabotage segment (R$ 237 million), as well as the inclusion of new companies and the exchange impact on the conversion of expenses from foreign subsidiaries (R$ 117 million), offset by the reduction in provisions for doubtful debts (R$ 97 million).

	Negative impact on the financial result (R$ 1,440 million) due to the increase in financing volume over 2008 and the impact of the dollar appreciation on foreign debt, in addition to higher exchange- rate losses on foreign investments due to the appreciation of the Real in the 1H-2009, as shown below:

Net Financial Results	(3,310)	(1,870)	(1,440)

• The decline in equity income (R$ 538 million) due to gains from the change in equity interests resulting from the corporate restructuring in 2008 (R$ 409 million). In 2009, the positive result from the petrochemical sector and other subsidiaries, in addition to reducing goodwill amortizations, offset provisions for losses on the acquisition of a 50% interest in the Pasadena refinery and Trading Company (USA) for a judicially arbitrated price (R$ 341 million).

• A negative minority interest impact (R$ 1,768 million), due to the result from the Special Purpose Companies caused by the impact of the exchange variation on their debt.

Due to the average inventory period of 60 days, international oil and oil product prices, as well as the impact of the exchange rate on imports and government take are not fully reflected in the cost of goods sold in the actual period, but in the subsequent period.

(*) In the quarterly COGS comparison, note that COGS in the 1Q-2009 was negatively impacted by higher unit costs formed in previous periods. This trend was reversed as of the 2Q-2009.

• A R$ 500 million reduction in the following operating expenses:

• Other operating expenses (R$ 258 million) due to higher gains from fiscal incentives (ADA and Sudene) and reduced losses from the decline in commodity prices and contractual fines;

• Exploration costs (R$ 220 million), lower expenses with the write-off of dry or economically unviable wells (R$ 366 million), offset by higher geological and geophysical costs (R$ 144 million);

• Selling expenses (R$ 118 million), due to the decline in chartered vessel freight costs, offset by increased sales and promotion costs.

• A reduction in the financial result (R$ 1,612 million), due to higher exchange losses on foreign investments, offset by reduced exchange losses on financing, as shown in the table below:

• An increase in equity income (R$ 744 million), reflecting the result from the petrochemical sector offset by the result from associated companies abroad (R$ 305 million) and 1Q-2009 provisions for losses in the USA (R$ 410 million).

• A negative minority interest impact (R$ 1,535 million) due to the result from the Special Purpose Companies, in turn caused by the impact of the exchange variation on their debt.

• A reduction in income tax and social contributions (R$ 645 million), due to the tax benefit resulting from the provisioning of interest on equity in the 2Q-2009.

PETROBRAS SYSTEM		Operating Performance

Exploration and production – thousand barrels/day

Increased output from P-52 and P-54 (Roncador), together with the start-up of P-53 (Marlim Leste), P-51 (Marlim Sul) and FPSO Cidade de Niterói (Marlim Leste), more than offset the natural decline in the mature fields.

Increased production from P-53 and the start up P-51 (Marlim Sul) and FPSO-Cidade de Niterói (Marlim Leste) in January/2009 and February/2009, respectively, more than offset the natural decline in the mature fields.

Consolidated international oil and NGL production increased due to the start-up of production in Nigeria in July 2008, partially offset by the reduction in Ecuador due to the sale of part of the interest in Block 18.

Consolidated gas production dipped by 1% due to the reduction in Brazil’s imports of Bolivian gas until April/2009 and lower consumption by thermal plants as a result of increased production by the hydro plants, offset by the increased interest in Sierra Chata, in Argentina, in the 4Q-2008.

Consolidated international oil and NGL production moved up due to the start-up of the Akpo Field, in Nigeria, in March/2009.

Consolidated gas production increased by 6% due to the increase in Brazil’s imports of Bolivian gas as of May/2009.


PETROBRAS SYSTEM		Operating Performance

Refining, Transportation and Supply – thousand barrels/day

Processed crude volume in the country’s refineries fell due to the scheduled stoppages in distillation units.

The 1% quarterly decrease was due to the programmed stoppage in the distillation units.

Processed crude in the overseas refineries rose by 17% due to the inclusion of the Japanese refinery acquired in April/08, in addition to the improved operating performance by the U.S. refinery.

In the 2Q-2009, processed crude in the overseas refineries fell by 10%, due to a scheduled stoppage in the Japanese refinery in May/2009.

Costs

Lifting Cost (US$/barrel)

Excluding the impact of the depreciation of the Real, the lifting cost in Brazil climbed by 4% over the 1H-2008 due to the increased number of well interventions and equipment maintenance in P-34, wells in the Marlim field and the Pargo platform, as well as higher personnel expenses.

Excluding the impact of the appreciation of the Real, the unit lifting cost in Brazil edged up by 2%, chiefly due to higher expenses with extraordinary well interventions in Campos Basin.


PETROBRAS SYSTEM		Operating Performance

The lifting cost fell due to the decrease in the average Brazilian oil price used to calculate the government take, partially offset by the increase in the special participation tax rate due to higher output from the new platforms.

The lifting cost moved up due to the increase in the average Brazilian oil price used to calculate the government take, thanks to the international price recovery.

The international unit lifting cost increased due to higher third-party service costs in Argentina, higher prices and the start-up of production in Nigeria, where costs are lower than the average in the Company’s international segment.

The quarter-over-quarter increase was due to higher material and third-party service costs in Argentina and the higher number of well interventions, partially offset by higher output.


PETROBRAS SYSTEM		Operating Performance

Refining Cost (US$/Barrel)

Excluding the impact of the depreciation of the Real, the domestic refining cost moved up by 1%, due to higher personnel expenses resulting from the 2008/2009 collective bargaining agreement and increased expenses with materials and lower feedstock processed.

Excluding the impact of the depreciation of the Real, the refining cost increased by 8% due to greater expenditure on conservation and repairs, and increased expenses with materials associated with production.

The international refining cost fell by 7% due to the higher volume of processed crude in the Pasadena refinery (USA) following the scheduled stoppage in the 1Q-2008, together with the inclusion of the Japanese refinery as of April 2008, whose refining costs are lower than the international average.

The quarter-over-quarter upturn was chiefly due to reduced production in Japan due to the scheduled stoppage in May/2009 and maintenance of the alkylation unit in the USA.


PETROBRAS SYSTEM		Operating Performance

Corporate Overhead – Parent Company (US$ million)

Excluding the impact of the depreciation of the Real, corporate overhead fell by 1% over the 1H-2008 due to reduced expenses from sponsorships and advertising, partially offset by the upturn in data-processing and personnel expenses.

Discounting the appreciation of the Real, corporate overhead increased by 8% over the previous quarter, due to higher data-processing, sponsorship and personnel expenses.

Sales Volume – thousand barrels/day

Domestic sales volume fell by 5% over the 1H-2008, led by diesel and natural gas. Diesel sales were impacted by the non-operation of the emergency diesel-powered thermal plants in the 1H-2009 (as occurred last year), the reduction in economic activity, the increase in the percentage of biodiesel from 2% to 3% as of July/2008 and the decline in the grain harvest. Natural gas sales were also jeopardized by the economic slowdown, the replacement of gas with fuel oil for industrial use, and reduced demand from the thermal plants due to higher reservoir levels in the Southeast compared to the beginning of 2008.

Exports increased 13% year-on-year, led by oil, thanks to increased output, especially from the operational start-up of FPSO – Cidade de Rio das Ostras (Badejo), P-53 (Marlim Leste), P-51 (Marlim Sul) and FPSO – Cidade de Niterói (Marlim Leste), as well as reduced domestic demand.

⁽¹⁾Comments on the results by business area begin on page 19 and their respective financial statements on page 32.

⁽²⁾In the international business segment, given that all operations are executed abroad, comparisons between the periods are influenced by foreign exchange variations in dollars or in the currency of those countries in which the companies in question are headquartered. As a result, there may be substantial variations in Reais, primarily arising from and reflecting changes in the exchange rate.


PETROBRAS SYSTEM		Operating Performance

RESULTS BY BUSINESS AREA

Petrobras is a company that operates in an integrated manner, with the greater part of oil and gas production in the Exploration and Production area being sold or transferred to other Company areas.

The main criteria used to report results per business area are as follows:

a) Net operating revenues: revenues from sales to external clients, plus intra-Company sales and transfers, using internal transfer prices established between the various areas as a benchmark, with assessment methodologies based on market parameters;

b) Operating income: net operating revenues, plus the cost of goods and services sold, which are reported per business area considering the internal transfer price and other operating costs for each area, plus the operating expenses effectively incurred by each area;

c) The entire financial result is allocated to the corporate group;

d) Assets: refers to the assets as identified by each area. Equity accounts of a financial nature are allocated to the corporate group.

The lower result reflected the new level of international oil prices and the increase in exploration costs due to higher geological and geophysical costs.

Part of these effects were offset by the 7% increase in average daily oil and NGL production and the lower government take.

The spread between the average domestic oil sale/transfer price and the average Brent price narrowed from US$ 13.25//bbl in the 1H-2008 to US$ 10.86/bbl in the 1H-2009.

The quarter-over-quarter results increase was due to the upturn in international oil prices and the increase of 7% in the oil sale/transfer volume, as well as the reduction in exploration costs due to the write-off of dry or economically unviable wells.

These factors were partially offset by the higher government take and increased geological and geophysical costs

The spread between the average domestic oil sale/transfer price and the average Brent price fell from US$ 12.17/bbl in the 1Q-2009 to US$ 10.11/bbl in the 2Q-2009.

The year-on-year improvement in the Supply result was due to lower oil acquisition/transfer costs and reduced imported oil product costs, reflecting the new level of international oil prices.

These effects were partially offset by the following factors:

• The reduction in average oil product prices due to reduced export prices and, in Brazil, to the lower price of those oil products pegged to international prices; gasoline and diesel prices remained at 2008 levels until June 2009;


PETROBRAS SYSTEM		Operating Performance

• Higher operating expenses, particularly from the adjustment of inventories to market value and from judicial contingencies.

The increase in the quarter-over-quarter result was due to the following factors:

• Higher sales volume in Brazil and abroad;

• Higher average export prices;

• The sale, in the 2Q-2009, of inventories formed in the previous quarter at a lower acquisition cost;

• Increased equity income, reflecting the petrochemical sector result.

These effects were partially offset by the reduction in average domestic oil product prices due to the downturn in diesel and gasoline prices in June 2009.

The improved result was due to lower electricity purchase costs due to the reduction in the difference settlement price, the greater availability of electricity for commercialization, due to the recovery of the peg, and the increase in fixed revenue from auctions, as well as higher electricity exports. Other contributory factors included the conclusion of infrastructure projects, which facilitated gas production outflow, thereby avoiding the failure-to-supply penalties incurred in the 1H-2008.

These effects were partially offset by reduced thermal power output due to higher hydroelectric reservoir levels and lower gas sales volume.

The quarter-over-quarter result recorded an upturn due to higher electricity sales/generation margins generated by the reduction in spot market acquisition costs, increased export volume and lower gas import costs.

These effects were partially offset by the reduction in the average gas sales price.

The year-on-year decline was caused by narrower sales margins, in turn due to lower average sales prices. This was partially offset by the 10% upturn in sales volume, primarily thanks to the consolidation of ALVO Distribuidora, despite the consequent increase in SG&A expenses.


PETROBRAS SYSTEM		Operating Performance

The Company’s share of the fuel distribution market climbed from 35.2% in the 1H-2008 to 38.4% in the 1H-2009.

The higher result was caused by the 9% increase the sales margins and the 5% upturn in sales volume.

These effects were partially offset by higher SG&A expenses due to increased freight costs.

The segment recorded a 38.0% share of the fuel distribution market in the 2Q-2009, versus 38.8% in the previous quarter.

The main events impacting the year-on-year reduction were:

• The reduction in gross profit due to lower international oil prices;

• Lower equity income due to losses on investments in the USA from the acquisition of the remaining 50% of the Pasadena refinery.

Higher oil prices and the upturn in sales volume due to the start-up of production in Akpo, in Nigeria, increased gross profit by R$ 189 million.

The constitution of provisions for losses on investments in the USA in the 1Q-2009 also contributed to the improvement.

The increase in the negative result was due to the upturn in the negative financial result (R$ 1,440 million), as dealt with on page 6, and the minority interest result, reflecting the impact of appreciation of the Real against the dollar on the debt of Special Purpose Companies and controlled companies that are not wholly-owned by Petrobras or its subsidiaries.

These effects were partially offset by the increase in income tax and social contribution credits due to the tax benefit generated by provisions for interest on equity.


PETROBRAS SYSTEM		Operating Performance

The increase in the negative result was due to the upturn in the negative financial result (R$ 1,612 million), as mentioned on page 10, and the minority interest result, despite the increase in income tax and social contribution credits.
