PETROBRAS SYSTEM  

A Word from the President, Mr. José Sérgio Gabrielli de Azevedo

It is with enormous pleasure that I present the second-quarter 2005 results to the investors, shareholders and the general public for the first time as President of the Company.

The second quarter of 2005 was marked by a strong increase in oil production in Brazil. Platforms P-43, P-48 and FPSO in Marlim Sul were key to achieving the production volume of 1,730 thousand bbld, 12% higher than the production in the first quarter of 2005 (1,543 thousand bbld) and 18% higher than production in the same quarter of last year (1,461 thousand bbld). This extraordinary operating performance is a consequence of the efforts undertaken by the Company and in relationships with suppliers, allowing us to move quickly in various stages of the installation of these units in the least amount of time possible, plus the excellent undersea work that allowed acceleration in the production curve. These platforms achieved the peak production just 6 months after they began operating.

With daily production close to 1,800 thousand bbld (record of 1,834 thousand bbl on June 23), we are on track to meet the goals outlined in our Strategic Plan and we have taken large steps towards self-sufficiency. Over the next 12 months, we are forecasting the installation of four more units: P-50, P-34, Golfinho I and Piranema, totaling nearly 360,000 bbld in additional capacity.

Refining performance and the increase in domestic production have allowed Petrobras to invert its commercial balance and become a net exporter of oil and oil products. In the second quarter of 2005, we were net exporters of 148,000 bbld (oil and oil products), generating a commercial balance of US$ 900 million in the period. And for the first time in our history we were net exporters of 20,000 bpd, even considering the natural gas imports from Bolivia.

Regarding economic-financial performance, our cash generation remained high – R$ 11,8 billion (measured by EBITDA), which enabled us to reduce our net debt, and we surpassed the levels set in our ambitious investment program. In the quarter, R$ 5,8 billion were invested in Brazil and abroad, including investments via Special Purpose Entities, and this amount was R$ 11 billion in the first half of 2005.

Our net income was R$ 4,9 billion, which is a 49% growth over the second quarter of 2004. This result is due to the increased domestic production of oil and gas, to the higher volumes sold in the internal market, to the higher prices for oil products in the internal market at the end of 2004, and to the growth in revenues from exports – which reflected the higher oil prices in the international markets and the larger volume exported – combined with the Company’s already-highlighted operating performance.

In the petrochemical area we closed an important agreement to build a modern industrial unit for the production and commercialization of polypropylene. The new plant will use propane as its raw material - to be furnished by the Paulínia refinery - and operation start-up is planned for 2007 with initial production of 300,000 tons/year. This project marks Petrobras’ intention to recover its investments in the petrochemical sector and add value to the refining chain.

We launched the new Diesel 500, with 500 ppm (parts per million of sulphur), which has 75% lower sulphur content. Developed in our refineries, this product supports Petrobras’ policy of making social responsibility and environmental excellence a priority. But the challenge continues; by the year 2010 we will make a higher-quality diesel available to the market. This new diesel will have even lower sulphur content, and it will meet the most rigorous existing environmental standards.

Thus, we are on the right path towards achieving the goals set out in our Strategic Plan: an unmatched portfolio of projects, extraordinary production growth, adaptation of the refining facilities to handle more heavy crude processing, continuous improvement in the quality of fuels, increase of natural gas supply, and the recovery of our petrochemical investments. These actions, aligned with social responsibility, will allow ongoing generation of value for our shareholders.

. Others      27    154    181 
         
      11.039    (4.729)   6.310 
         

•   Increase in Sales Expenses (R$ 566 million), due to the increase in commercialized volume and sea freight, considering the increase in exports.
 
•   Increase in General and Administrative Expenses (R$ 571 million), following higher salary and benefits expenses projected in the 2004/2005 Collective Bargaining Agreement, the larger workforce and expenses related to the pension and health plans due to the actuarial revision in December 2004, plus expenses for network maintenance and software licenses
 
•   Increase in other operating expenses (R$ 1.166 million), mainly due to the losses or legal accords and an additional provision for contingencies (R$ 242 million), expenses related to institutional relations and cultural projects (R$ 100 million), and with the health and pension plans of retirees and pensioners due to the actuarial revision in December 2004 (R$ 430 million).
 
•   Reduced tax expenses (R$ 390 million), because of the change in legislation as of August 2004 (Decree Number 5,164/04), which reduced to zero the PIS/PASEP and COFINS amounts levied on financial revenues.
 
•   R$ 937 million improvement in the financial result, highlighting the following:
 
       Positive exchange rate and monetary variation (R$ 1.660 million effect), which includes, in part, the effects of the real’s appreciation against the dollar from January to June 2005 (11%), when compared to the depreciation of the real in the same period of the previous year (8%).
        This was offset by the R$ 723 million increase in net financial expenses, mainly due to the decrease in financial revenues resulting from reduced short-term investments, as well as the profitability of the funds applied in the country, primarily linked to the exchange rate variation.
 
•   Reduction in the result from participation in relevant investments, loss of R$ 283 million in the first half of 2005, and a R$ 457 million gain in the first half of 2004 due to exchange rate losses on net equity of subsidiaries abroad, resulting from the 11% appreciation of the real against the dollar in the first half of 2005 (8% depreciation in 1H-2004).
 
•   R$ 546 million increase in the provision for income taxes and social contribution on profit, due to the increase in the net income which serves as the base for taxation, despite the provisioning of Interest on Own Capital on June 2005. This R$ 746 million improvement in profitability in the period was a consequence of its deductibility from the calculation base for the provision for income tax and social contribution on profit.

Exploration and Production – Th. Barrels/day

Production of domestic oil and LNG in the 1H-2005 increased 12% over the 1H-2004, due to the start-up of FPSO-MLS (Marlim Sul) in June 2004, and platforms P-43 (Barracuda) and P-48 (Caratinga) in December 2004 and February 2005, respectively.

In 2Q-2005, domestic oil and LNG production increased 12% over 1Q-2005 production, a consequence of increased operations at platforms P-43 and P-48 in the Barracuda and Caratinga fields. In June 2005, the Company reached a new oil production record of 1,834 thousand barrels per day, 23% higher than the volume reached in May 2005 (1,493 thousand barrels per day).

In 1H-2005, international oil production fell 2% in comparison to 1H-2004, due to interventions in some wells in Argentina and Venezuela. Gas production rose 5% due to increased production at the Bolivia unit, following the increase in gas demand in Brazil and Argentina.

In comparison to 1Q-2005, international oil production increased 2% because of the gradual development in production in block 18 in Ecuador. Gas production remained stable.

Refining, Transport and Supply – Th. Barrels/day

Processed throughput (primary processing) in the refineries in the country fell 2% in 1H-2005, compared to 1H-2004, due to the programmed stop at REPLAN and RECAP, at the distillation units, and at the cracking and propane units, respectively.

Costs

Lifting Cost (US$/barrel)

The lifting cost in the country without government take in 1H-2005 increased 28% over 1H-2004, due mainly to higher expenses for technical services for restoration and maintenance, mobilization and construction of structures and equipments, personnel transport, support for vessels, undersea operations, platform freight with third parties, consumption of chemical products to clear out and eliminate toxic gases – principally at Marlim, plus the increases in salaries and benefits in the 2004/2005 Collective Bargaining Agreement, the larger workforce and the actuarial revision at the end of 2004, which increased the expenses provisioned for the health and pension plans. Discounting the effects of the real’s 13% appreciation, associated with the percent of expenses in domestic currency over the expenses related to this activity, the unit lifting cost increased 16% in relation to 1H-2004.

The 18% decrease in the unit lifting cost in the country without government take in 2Q-2005 in relation to 2Q-2004 is mainly due to higher expenses in the first quarter because of the stops at the fixed platforms in the Namorado 1 and 2 fields, in the Cherne 1 and 2 fields, in the Garoupa 1 field, and the in the Corvina field, plus the general stop at platform P-19 (Marlim) for a change of gas flaring equipment. These effects were partially offset by higher expenses in 2Q-2005 for the use of well intervention services and undersea line maintenance, and in access routes to production fields. Discounting the effects of the 7% appreciation of the real, the unit lifting cost fell 24% in relation to 1Q-2005.

In 1H-2005, the unit lifting cost in the country with government take grew 35% over 1H-2004, a result of the already-mentioned higher operating expenses, and the larger expenses with government take due to the increase in the average reference price for domestic oil, based on the variations in international market prices, and the 13% appreciation of the real against the U.S. dollar. In comparison to 1Q-2005, the 2Q-2005 lifting price in Brazil, considering government take, fell 2% due to the mentioned decrease in expenses. This fall was partially offset by the higher average reference price for domestic oil.

 

In 2Q-2005, the international unit lifting cost rose 7% over 1Q-2005, because of higher expenses for third-party services, materials, personnel and electricity consumption at the fields in Argentina and Venezuela. At the Colombia unit, expenses related to third-party services for equipment maintenance, expenses for chemical treatment of water and vehicle leasing contributed to the increase.

Refining Cost (US$/barrel)

The unit refining cost in the country in 1H-2005 increased 50% over 1H-2004, due to higher expenses for corrective maintenance at RPBC, RLAM, REDUC and REPLAN, plus the higher personnel expenses arising from the increases incurred in salaries and benefits approved in the 2004/2005 Collective Bargaining Agreement, and the actuarial revision, at the end of 2004, and to the expenses provisioned for the health and pension plans. Discounting the effects of the 13% appreciation of the real associated to the percentage of expenses in domestic currency on the expenses of this activity, the unit refining cost increased 34% over 1H-2004.


7



In comparison to 1Q-2005, the unit refining cost in the country in 2Q-2005 rose 10%, due to the greater consumption of materials and use of contracted services for realization of programmed stops at REDUC, REGAP, REPLAN, RPBC and REPAR.

In 1H-2005, the average international unit refining cost increased 14% in relation to 1H-2004, due to higher expenses for personnel, electricity and contracted services at the refineries in Argentina, plus the expenses for equipment maintenance, electricity and personnel in Bolivia.

The average international refining cost in 2Q-2005 rose 19% in relation to 2Q-2004, mainly due to the programmed stops at the Bahia Blanca and San Lorenzo units in Argentina, plus the expenses for materials, industrial installations, personnel, third-party services, security and equipment maintenance in Bolivia.

Overhead (US$ million)

In comparison to 1H-2004, corporate overhead in 1H-2005 grew 56%, due to higher expenses with contracted services, mainly linked to data processing, health, safety and environment, sponsorship, institutional advertising and publicity, expenses for property rental, and the increased expenses for salaries and benefits approved in the 2004/2005 Collective Bargaining Agreement, and revision of the actuarial calculation linked to the health and pension plans. Discounting the effects of the 13% appreciation of the real, and considering that all expenses are in reais, overhead increased 34% over 1H-2004.

The sales volume of oil products remained stable in the domestic market in 1H-2005 in relation to 1H-2004, highlighting the increased sales of gasoline and diesel, which were offset by reduced sales of naphtha and fuel oil. Retraction of fuel oil consumption in 1H-2005 compared to 1H-2004 was due to strong competition from substitute products such as coal, coke, biomass and wood.

RESULTS BY BUSINESS AREA

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

The following highlights the main criteria used to report the results by business area:

a) Net operating revenues: considered to be the revenues related to sales made to external clients, plus the billing and transfers between the business areas, using the internal transfer prices defined between the areas as reference, with reporting methods based on market parameters.

b) Included in operating profit are the net operating revenues, costs of goods and services sold – which are reported by business area considering the internal transfer price – and the other operating costs of each area, as well as the operating expenses, which include the expenses effectively incurred by each area.

c) Assets: include the assets identified in each area.

E&P – In 1H-2005, the net income reported by the Exploration & Production area was R$ 10.391 million, 39% higher than the net income reported in the same period of the prior year (R$ 7.476 million), due to the R$ 4.710 million increase in gross income reported with the sales and transfers of oil, reflecting the higher international prices and the 12% rise in oil and LNG production, and the 5% increase in natural gas, despite the 13% appreciation in the average rate of the real against the U.S. dollar and the lower valuation of heavy crude in the international market in comparison to the lighter crudes.

The spread between the average price of domestic oil sold/transferred and the average Brent price rose from US$ 2.49/bbl in 1H-2004 to US$ 9.16/bbl in 1H-2005.

In 2Q-2005 the net income reported by the Exploration & Production area was R$ 5.807 million, 27% higher than the net income reported in the previous quarter (R$ 4.584 million), due to the R$ 2.569 million growth in gross income, reflecting the increase in international oil prices as well as the 12% increase in oil and LNG production, and the 7% increase in natural gas production, despite the 7% appreciation of the average rate of the real against the U.S. dollar and the lower valuation of heavy crude in the international market compared to lighter crude.

The spread between the average price of domestic oil sold and transferred, and the average Brent price, fell from US$ 10.02/bbl in 1Q-2005 to US$ 8.55/bbl in 2Q-2005.

SUPPLY – In 1H-2005, the net income reported by the Supply area was R$ 3.500 million, 142% higher than the net income reported in the same period of the prior year (R$ 1.445 million), a result of the R$ 3.221 million increase in the gross income, with highlight for the following factors:

These items were partially offset by the following:

Another factor that contributed to offsetting the increase in the gross income was the R$ 135 million rise in sales expenses, due to the increase in volumes commercialized and sea freight.

In 2Q-2005, the net income reported by the Supply area was R$ 1.941 million, 25% higher than the net income reported in the previous quarter (R$ 1.559 million), due to the R$ 495 million increase in gross income, which was impacted by the following:

10



Another factor that contributed to the improved result from the Supply area was the R$ 256 million reduction in operating expenses, which in the previous quarter was impacted by R$ 289 million in contingencies for legal proceedings.

These items were partially offset by the 5% reduction in the volume of oil products sold in the external market.

GAS AND ENERGY – In 1H-2005 the Gas and Energy business area reported profit of R$ 153 million, against a loss of R$ 326 million reported in the same period of the previous year, a function of the following:

These items were partially offset by the R$ 316 increase in operating expenses, due to the R$ 306 million increase in operating expenses for thermoelectric plants, mainly related to idleness, as well as the R$ 228 million growth in the participation on non-controlling shareholders, considering the better results reported by Transportadora Brasileira Gasoduto Bolívia Brasil-TBG.

In 2Q-2005, the net income reported by the Gas and Energy business area was R$ 212 million, compared to the R$ 59 million loss reported in the previous quarter. This result was due to the net financial revenues of R$ 538 million, considering the 12% appreciation of the final rate of the real against the U.S. dollar. A net financial expense of R$ 98 million was reported in the previous quarter.

This result was partially offset by the R$ 229 million increase in expenses related to participation of non-controlling shareholders, due to the better results reported by Transportadora Brasileira Gasoduto Bolívia Brasil-TBG.

DISTRIBUTION – In line with the strategic objectives to increase participation in the GLP Distribution segment and consolidation of the distribution market for automotive fuel in determined regions of Brazil, the distribution businesses now include the operations of Liquigás Distribuidora S.A., as of its acquisition in August 2004 by Agip do Brasil S.A.

In 1H-2005, the Distribution business area reported a net income of R$ 283 million, 15% higher than the net income reported in the same period of the previous year (R$ 246 million), due to the R$ 529 million increase in the gross income, noting the consolidation of the company Liquigás, which had positive impacts on the volume sold, 22% greater in relation to the same period of the previous year.

These items were partially offset by the R$ 459 million increase in operating expenses, particularly the increased expenses for commercialization and distribution of products and with personnel, which were also affected by the consolidation of Liquigás.

The Company’s share in the fuel distribution market in 1H-2005 was 34.7%, including the company Liquigás, while in the same period of the prior year it was 32.3% .

The effects of consolidation in August 2004 of Liquigás resulted in an increase of R$ 265 million in the gross income, and a R$ 35 million decrease in the net income in the segment.

In relation to the previous quarter when the net income reported by the Distribution business area was R$ 160 million, the net income in 2Q-2005 was 23% lower, due to the R$ 27 million reduction in the gross income, and the R$ 71 million increase in the operating expenses, particularly the increased expenses in the commercialization and distribution of products and for the additional provision for doubtful debtors.

The market share for fuel was 34.3% in 2Q-2005, including the company Liquigás, and 35.1% in 1Q-2005.

INTERNATIONAL – In 1H-2005 the International business area reported a net income of R$ 519 million, 101% higher than the net income of R$ 258 million reported in the same period of the prior year.

This increase in net income is due to the following:

11



  the appreciation of the real against the U.S. dollar (24%).

In 2Q-2005 the International business area reported a net income of R$ 168 million, 52% lower than the net income of R$ 351 million reported in the previous quarter, due to the R$ 235 million reduction in gross income, which was impacted by the lower sales volume. This was partially offset by the R$ 66 million decrease in financial expenses, and both were mainly due to the effect of the appreciation of the real against the U.S. dollar (12%) in the process of exchange rate conversion.

CORPORATE – The units that comprise the Corporate area of the Petrobras System generated a loss of R$ 3.030 million in 1H-2005, 55% greater than the loss reported in 1H-2004 (R$1.960 million), with highlight for the following factors:

These items were partially offset by the following:

In 2Q-2005, the loss reported by the Corporate area was R$ 1.826 million, 52% higher than the loss reported in the previous quarter (R$ 1.204 million), highlighting the following aspects:

These items were partially offset by fiscal savings of R$ 746 million, due to the provision of interest on own capital in June 2005.

(1)      Net Operating Revenues and the COGS relative to the year 2004 were reclassified between the International segment and the Supply segment regarding offshore operations that were being allocated to the International segment. Considering that the margins obtained in these operations are normally very low, there was no significant impact on the results reported by these segments.
 
(2)      With the intent of adapting the results by business area to the new procedures arising from implantation of the SAP-R/3 system, as of 2005 the revenues from commercialization of oil to third parties will be allocated as per the points of sale, which may belong to the Exploration & Production or Supply areas. Until 2004, the commercialization of oil was fully allocated to the Exploration & Production area.
 
  Considering that the methodology used for the internal transfer price of oil is based on market parameters and that all oil commercialized by the Supply area comes from transfers from the Exploration & Production area, this adaptation produces practically no effects on the results of the areas, and ends up as an increase in the line “Net Operating Revenues” in the Exploration & Production area, offsetting a reduction in the “Net Operating Revenues with Third Parties” line, and increases in the “Net Operating Revenues with Third Parties” and the “Cost of Goods and Services Sold” lines in the Supply area.
 
  Another change due to the implantation of the SAP-R/3 system is related to a natural gas parcel transferred by the Gas & Energy area to Supply, for specification at natural gas processing units (UPGN), and further commercialization by the Gas & Energy area. Considering that the internal transfer prices practices in these transactions are the same, these changes do not produce any impact on the gross income of the Supply and Gas & Energy areas, only increases in the Intersegment Revenues and in the COGS.

By means of Official Document Number 11/2004, of June 23, 2004, the Integrated Audit Commission ANP/STN presented the final audit report certifying and homologating the amount in the petroleum and alcohol account and enabling the offseting of accounts between Petrobras and the government. This is now underway.

As per Law Number 10,742 of October 6, 2003, the offset of accounts with the government should have occurred by June 30, 2004. Petrobras, after having furnished all the information required by the National Treasury Secretary – STN, is in discussion with the Ministry of Mines and Energy – MME, seeking to equalize the disparities that still exist between the parties in an effort to conclude the offset of accounts with the government, as per Provisionary Measure Number 2,181-45, dated August 24, 2001.

On July 2, 2004, the government made a deposit in the amount of R$ 172 million, equivalent to National Treasury Notes – H Series (NTNs-H) that were issued in favor of PETROBRAS to guarantee payment of the amount due in relation to the petroleum and alcohol account, as they matured on June 30, 2004. Of this amount, R$ 8 million was available to PETROBRAS , and the remaining amount of R$ 165 million was placed in an open account in favor of the Company as a blocked deposit linked to the STN order. The amount of the account may be paid through the issue of National Treasury bonds in a value equal to the final amount of the account rectification or with other amounts that PETROBRAS may owe to the federal government, including tax amounts or a combination of the foregoing options.

. According to consolidated information as of June 30, 2005    70.100    9.951 
     

* As per CVM Instruction Number 247/96, the losses that are considered to be of a non-permanent type (temporary) on investments evaluated by the equity in results of non-consolidated companies method, whose invested company does not show signs of paralysis or need for financial help from the investor company, should be limited to the value of the controlling company’s investment. Therefore, the losses occasioned by unfunded liabilities (negative net shareholder’s equity) of controlled companies did not affect the results and the net shareholder’s equity of Petrobras in 1H-2005, generating a conciliatory item between the Financial Statements of Petrobras and the Consolidated Financial Statements.

6. Dividends and Interest on Own Capital

On June 17, 2005, the Board of Directors approved a distribution of remuneration to shareholders in the form of interest on own capital, as set forth in Article 9 of Law 9,249/95 and Decree Numbers 2,673/98 and 3,381/00. The R$ 2.194 million amount to be distributed corresponds to a gross value of R$ 2,00 per ordinary and preferred share and is being provisioned in the financial statements of June 30, 2005, to be paid out until January 31, 2006, based on the shareholder position on June 30, 2005.

As per the terms of Decree Numbers 2,673/98 and 3,381/00, if payment occurs after December 31, 2005, variation in the SELIC rate will be applied, from December 31, 2005 to the date of the effective payment. This interest on own capital must be discounted from the remuneration to be distributed at the end of 2005, and is subject to a 15% (fifteen per cent) withholding income tax, except for the shareholders that declare that they are exempt or immune.

7. Petrobras Stock Split

The General Extraordinary Assembly, which met on July 22, 2005, deliberated and approved: a stock split representing 300% of the existing shares comprising the Company’s corporate capital, resulting in the free distribution of 3 (three) new same-type shares for each 1 (one) share, based on the shareholder position on August 31, 2005. Thus, the corporate capital in the amount of R$ 32.896 million will be divided into 4,386 million shares without nominal value on September 1, 2005, with 2,537 million in ordinary shares and 1,849 million in preferred shares, and the relationship between the American Depositary Receipts (ADR) and the shares corresponding to each type will be altered from the current “one share per one ADR”, to “four shares per one ADR”.
