                     COMMENTS FROM THE CEO, MR. JOSE EDUARDO DE BARROS DUTRA







We are completing our first year of management at the Company. It was a year of
multiple successes but also of great challenges in light of our many goals,
including transparency in our actions and fostering innovations within the
Company's administration. The year 2003 also marked our 50-year anniversary, and
we sought to remember the accomplishment of those who helped build what is today
one of the world's largest oil companies.

Market confidence in our Company allowed us to raise U.S.$ 5.4 billion in the
international capital markets during the year. In particular, investor demand
for issuances of our global notes exceeded the actual amount issued on several
occasions, and our notes sold in record time. Demand was strong notwithstanding
the fact that these notes do not have any additional guarantee or political risk
insurance. They are important milestones for the Company, not only for the
reduction in costs and lengthening of our debt maturity profile (the 15-year
bonds issued on December 10, 2003 are of the longest maturity ever issued by the
Company), but also because we were able to diversify our investor base. A
significant portion of these notes were acquired by investors from the high
grade and high yield markets, which are comprised of North American investors
who are typically more interested in financing companies within the United
States.

Among our principal achievements in 2003 we would like to highlight: (1) the
revision of our strategic plan, (2) the implementation of a new human resources
policy directive, (3) the improvement of the bidding process, particularly in
relation to platforms P-51 and P-52, and (4) the ongoing efforts to increase our
share in the natural gas and energy market. The intent of these efforts is to
increase operating efficiency and not only obtain higher returns for our
shareholders but also contribute significantly to Brazilian society in general.

In 2003, we received various awards recognizing our successes on a number of
fronts, including the award for Bond of the Year from Euromoney Magazine for our
U.S.$ 500 million issuance in June and the Investor's Choice for Best Website
Award given by MZ Consult.

We arrived at the end of this first year determined to overcome new challenges
and always vigilant of our goal to keep the Company on its path of positive
results, without losing sight of transparency, ethics and social and
environmental responsibility.

     U.S. GAAP and should not be considered in isolation or as a substitute for
     total long-term debt calculated in accordance with U.S. GAAP. Our
     calculation of net debt may not be comparable to the calculation of net
     debt by other companies. Management believes that net debt is an

                        ANALYSIS OF OPERATING HIGHLIGHTS

Exploration and Production

Domestic crude oil and NGL production increased 2.7% to 1,540 thousand barrels
per day for 2003, as compared to 1,500 thousand barrels per day for 2002,
largely due to the start-up of new wells in the Marlim, Espadarte (ESPF) and
Albacora fields and installation of the production system in the Marlim Sul
field. The start-up of FPSO Brazil in the Roncador field in December 2002, and
the start-up of production in the Jubarte field in October 2002 and the Coral
field in February 2003, also contributed to increased production for 2003.

International crude oil and NGL production increased to 161 thousand barrels per
day for 2003, as compared to 35 thousand barrels per day for 2002, principally
due to the inclusion of production from Petrolera Santa Fe, Petrobras Energia
Participaciones S.A. - PEPSA (formerly known as Perez Companc S.A.) and
Petrolera Entre Lomas S.A. - PELSA (formerly known as Petrolera Perez Companc
S.A.) in Argentina, Ecuador, Venezuela and Bolivia into our production results.
Part of this increase was offset by the reduced production in mature fields in
Angola, Colombia and the United States.

Reserves

Our proved reserves in Brazil, estimated by management in accordance with the
rules and regulations of the U.S. Securities and Exchange Commission (the
"SEC"), amounted to 10.40 and 10.05 billion barrels of oil equivalent for 2003
and 2002, respectively. Total production reached 615 million barrels of oil
equivalent for 2003, as compared to 604 million barrels of oil equivalent for
2002. As of December 31, 2003, our proved reserves to production ratio was 16.9
years.

Lifting Costs

Our lifting costs in Brazil, excluding government take, increased 14.5% to U.S.$
3.48 per barrel of oil equivalent for 2003, from U.S.$ 3.04 per barrel of oil
equivalent for 2002. This increase was primarily related to increases in sea and
air transport expenses incurred in connection with our production operations.
Lifting costs also rose because of (1) increased consumption of materials and
maintenance services at ocean terminals, (2) higher expenses associated with
equipment and installation that provide operational support for these
activities, (3) salaries, benefits and charges incurred in connection with
salary readjustments for our larger workforce and (4) updating actuarial
calculations of postretirement benefits obligations.

Our lifting costs in Brazil, including government take (comprised of royalties,
special government participation and rental of areas), increased 22.4% to U.S.$
8.62 per barrel of oil equivalent for 2003, from U.S.$ 7.04 per barrel of oil
equivalent for 2002, due to the new special participation charge assessed to the
greater volume of production from the Marlim Sul field, the inclusion of the
Canto do Amaro and Roncador fields as fields subject to the special
participation tax and to the increase in domestic reference prices for domestic
crude oil.

Our international lifting costs increased 18.3% to U.S.$ 2.46 per barrel of oil
equivalent for 2003, as compared to U.S.$ 2.08 per barrel of oil equivalent for
2002. This increase was primarily due to the incorporation of the higher unit
lifting costs of Petrolera Santa Fe, PELSA and PEPSA, as well as the higher unit
lifting cost associated with the start of production of the San Antonio block in
Bolivia. This increase was partially offset by the decrease in maintenance
expenses at the Arauca field and the reduced consumption of natural gas and
diesel oil at the Upia field, both in Colombia.

Refining costs

Domestic unit refining costs increased 28.6% to U.S.$ 1.17 per barrel of oil
equivalent for 2003, as compared to U.S.$ 0.91 per barrel of oil equivalent for
2002, principally due to the higher costs of chemical products and catalyzers,
higher labor costs and higher costs for technical services to improve our
operating performance as well as planned stoppages at our refineries.

International unit refining costs increased 24.5% to U.S.$ 1.17 per barrel of
oil equivalent for 2003, as compared to U.S.$ 0.94 per barrel of oil equivalent
for 2002. This increase was primarily due to the incorporation of the higher
unit refining costs of PELSA and PEPSA in Argentina, as well as increased
expenses related to maintenance at the catalytic cracker units and boilers of
Eg3, our Argentine subsidiary that focuses on distribution.

Sales Volume

Our domestic sales volume, consisting primarily of sales of diesel oil,
gasoline, jet fuel, naphtha, fuel oil and liquefied petroleum gas, decreased
4.3% to 1,762 barrels per day for 2003, as compared to 1,842 barrels per day for
2002. The decrease in sales volume was primarily due to the contraction of the
Brazilian economy and the consequent loss of purchasing power among the
population.




            ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS


Overview

We earn income from:

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

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

o    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

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

Our expenses include:

o    costs of sales (which is comprised of labor expenses, cost of operating and
     purchases of crude oil and oil products and others); maintaining and
     repairing property, plants and equipment; depreciation and amortization of
     fixed assets and depletion of oil fields, and costs of exploration;

o    selling, general and administrative expenses; and

o    interest expense, monetary and foreign exchange losses.

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

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

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

o    related changes in domestic prices of crude oil and oil products, which are
     denominated in Reais;

o    Brazilian political and economic conditions;

o    fluctuations in the Real/U.S. dollar exchange rate; and

o    the amount of taxes and duties that we are required to pay with respect to
     our operations, by virtue of our status as a Brazilian company and our
     involvement in the oil and gas industry.




                 RESULTS OF OPERATIONS FOR 2003 COMPARED TO 2002

The comparison between our results of operations for 2003 and 2002 has been
affected by the 5.2% rise in the average Real/U.S. dollar exchange rate for 2003
as compared to the average Real/U.S. dollar exchange rate for 2002. For ease, we
refer to this change in the average exchange rate as the "5.2% decrease in the
value of the Real against the U.S. dollar in 2003, as compared to 2002."

Revenues

Net operating revenues increased 36.2% to U.S.$ 30,797 million for 2003, as
compared to U.S.$ 22,612 million for 2002. This increase was primarily
attributable to the alignment in 2003 of prices of certain oil products in the
Brazilian market with international prices of such products prevailing at the
end of 2002. The increase in net operating revenues was also attributable, to a
lesser extent, to an increase in sales volume outside Brazil (international
sales), which includes sales conducted by PEPSA and PELSA. This increase was
partially offset by a 4.3% reduction in sales volume in the domestic market,
primarily due to a decrease in Brazilian consumer demand.

Consolidated sales of products and services increased 29.4% to U.S.$ 42,690
million for 2003, as compared to U.S.$ 32,987 million for 2002, primarily as a
result of the increase in the price of certain oil products in the international
markets and the increase in sales volume outside Brazil (international sales).
Included in sales of products and services are the following amounts which we
collected on behalf of the Brazilian federal or state governments:

o     Value-added and other taxes on sales of products and services and social
      security contributions. These taxes increased 21.1% to U.S.$ 6,348 million
      in 2003, as compared to U.S.$ 5,241 million in 2002, primarily due to the
      increase in sales of products and services; and

o     CIDE, the per-transaction tax due to the federal government, which
      increased 8.0% to U.S.$ 5,545 million in 2003, as compared to U.S.$ 5,134
      million in 2002. This increase was primarily attributable to the increase
      in sales of products and an increase in the CIDE rate charged on certain
      oil products. The increase was partially offset by the effect of the 5.2%
      decrease in the value of the Real against the U.S. dollar in 2003, as
      compared to 2002.

Cost of sales

Cost of sales for 2003 increased 34.0% to U.S.$ 15,416 million, as compared to
U.S.$ 11,506 million in 2002. This increase was principally a result of:

o    an increase in taxes and charges imposed by the Brazilian government, which
     amounted to U.S.$ 3,081 million in 2003, as compared to U.S.$ 2,014 million
     in 2002. These taxes and charges included the special participation charge
     (an additional charge payable in the event of high production and/or
     profitability from our fields), which increased to U.S.$ 1,625 million in
     2003, as compared to U.S.$ 917 million in 2002, as a result of our
     increased production of crude oil during 2003, the inclusion of the Canto
     do Amaro and Roncador fields as fields subject to the special participation
     tax and the increase in domestic reference prices for domestic crude oil;

o    a net increase in cost of sales outside Brazil, excluding PEPSA and PELSA,
     of approximately U.S.$ 800 million, attributable to an increase in our
     sales volume, lifting costs and prices in the international markets;

o    a net increase of U.S.$ 634 million attributable to increased consumption
     of materials and maintenance services at ocean terminals, higher expenses
     associated with oil transport lines, including equipment and installation
     that provide operational support for these activities, and salaries,
     benefits and charges incurred in connection with salary readjustments for
     our larger workforce;

o    a U.S.$ 561 million increase in the cost of imports primarily attributable
     to the increase of crude oil and oil product prices in the international
     markets; and

o    a U.S.$ 431 million increase in costs associated with the consolidation of
     PEPSA and PELSA.

These increases were partially offset by:

o    a decrease of approximately U.S.$ 379 million in cost of sales related to
     the 4.3% reduction in our domestic sales volumes; and

o    a decrease of U.S.$ 39 million in cost of sales as expressed in U.S.
     dollars caused by the 5.2% decrease in the value of the Real against the
     U.S. dollar in 2003, as compared to 2002.

Depreciation, depletion and amortization

We calculate depreciation, depletion and amortization of exploration and
production assets on the basis of the units of production method. Depreciation,
depletion and amortization expenses decreased 7.5% to U.S.$ 1,785 million for
2003, as compared to U.S.$ 1,930 million for 2002. This decrease was primarily
attributable to the 5.2% decrease in the value of the Real against the U.S.
dollar in 2003, as compared to 2002, and to the effect of the adoption of SFAS
143 in 2003. In 2002, U.S.$ 284 million in abandonment costs were recognized as
depreciation, depletion and amortization in accordance with SFAS 19. In 2003, as
result of the adoption of SFAS 143, U.S.$ 21 million of depreciation on the
asset retirement obligations was recorded under depreciation, depletion and
amortization, while accretion expenses was recorded under exploration, including
exploratory dry holes. The decrease in depreciation, depletion and amortization,
was partially offset by an increase of depreciation, depletion and amortization
expenses of approximately U.S.$ 182 million incurred in connection with the
activities of PEPSA and PELSA.

Exploration, including exploratory dry holes

Exploration costs, including exploratory dry holes increased 17.7% to U.S. $ 512
million for 2003 as compared to U.S.$ 435 million for 2002. This increase was
primarily attributable to the increase of approximately U.S.$ 49 million in
exploration costs, including exploratory dry holes in connection with the
consolidation of PEPSA and PELSA and the recognition of U.S.$ 43 million in
accretion expense associated with abandonment costs. The increase in exploration
costs, including exploratory dry holes, was partially offset by the effect of
the 5.2% decrease in the value of the Real against the U.S. dollar in 2003, as
compared to 2002.

Impairment of oil and gas properties

For 2003, we recorded an impairment charge of U.S.$ 70 million, as compared to
an impairment charge of U.S.$ 75 million for 2002. In 2003, the impairment
charge was related to certain of our oil and gas producing properties in Brazil,
Colombia and Angola. In 2002, the impairment charge was related to certain of
our oil and gas producing properties in Brazil and Angola. These charges were
recorded based upon our annual assessment of our fields using prices consistent
with those used in our overall strategic plan and discounted at a rate of 13%, a
rate consistent with the rate used for internal project valuations.

Selling, general and administrative expenses

Selling, general and administrative expenses increased 20.1% to U.S.$ 2,091
million for 2003, as compared to U.S.$ 1,741 million for 2002.

o    Selling expenses increased 5.6% to U.S.$ 1,020 million for 2003, as
     compared to U.S.$ 966 million for 2002. This increase was primarily
     attributable to the consolidation of PEPSA and PELSA, which resulted in a
     U.S.$ 37 million increase in our 2003 selling expenses.

o    General and administrative expenses increased 38.2% to U.S.$ 1,071 million
     for 2003, as compared to U.S.$ 775 million for 2002. This increase was
     primarily attributable to an increase of U.S.$ 65 million in expenses
     related to technical consulting services from our increased outsourcing of
     selected non-core general and administrative activities, an increase of
     U.S.$ 41 million in expenses related to our profit sharing program, an
     increase of U.S.$ 43 million in expenses related to employee training, an
     increase of U.S.$ 57 million in general and administrative expenses
     recognized in connection with the consolidation of PEPSA and PELSA and an
     increase of U.S.$ 40 million in connection with the line by line
     consolidation of three thermoelectric power plants, which were consolidated
     in accordance with FIN 46. This increase in general and administrative
     expenses was partially offset by the effect of the 5.2% decrease in the
     value of the Real against the U.S. dollar in 2003, as compared to 2002.

Research and development expenses

Research and development expenses increased 36.7% to U.S.$ 201 million for 2003,
as compared to U.S.$ 147 million for 2002. This increase was primarily related
to our additional investments in programs for environmental safety, deepwater
and refining technologies of approximately U.S.$ 62 million, and was partially
offset by the effect of the 5.2% decrease in the value of the Real against the
U.S. dollar in 2003, as compared to 2002.

Equity in results of non-consolidated companies

Equity in results of non-consolidated companies registered a gain of U.S.$ 141
million for 2003, as compared to a loss of U.S.$ 178 million for 2002. This
increase was primarily attributable to:

o    a gain of U.S.$ 62 million for 2003 from our investments in natural gas
     distribution and petrochemical companies, as compared to a gain of U.S.$ 14
     million for 2002;

o    a gain of U.S.$ 59 million for 2003, as compared to a loss of U.S.$ 95
     million for 2002, from our equity investments in Compania Mega, an
     Argentine company that is engaged in natural gas activities, and which was
     adversely affected by the devaluation of the Argentine Peso against the
     U.S. dollar in 2002; and

o    a gain of U.S.$ 21 million for 2003, as compared to a loss of U.S.$ 98
     million for 2002, from our investments in thermoelectric power plants. The
     equity results for 2003 do not include our interests in three
     thermoelectric power plants that were consolidated in accordance with FIN
     46.

Financial income

We derive financial income from several sources, including:

o    interest on cash and cash equivalents. The majority of our cash equivalents
     are short-term Brazilian government securities, including securities
     indexed to the U.S. dollar. We also hold balances in U.S. dollar deposits;

o    long-term Brazilian government securities we acquired in connection with
     the privatization of our petrochemical assets; and

o    Government receivables, primarily the Petroleum and Alcohol Account.

Financial income decreased 47.3% to U.S.$ 602 million for 2003, as compared to
U.S.$ 1,142 million for 2002. This decrease was primarily attributable to a
reduction in financial interest income from short-term investments, which
declined 79.5% to U.S.$ 163 million for 2003, as compared to U.S.$ 793 million
for 2002. The reduction in financial income was also attributable to the 5.2%
decrease in the value of the Real against the U.S. dollar for 2003, as compared
to 2002. This decrease was partially offset by an increase of financial income
of approximately U.S.$ 80 million resulting from the consolidation of PEPSA and
PELSA in our 2003 financial results.





 Financial expense

Financial expense increased 61.1% to U.S.$ 1,247 million for 2003, as compared
to U.S.$ 774 million for 2002. This increase was primarily attributable to our
additional debt and an increase of approximately U.S.$ 194 million in financial
expenses resulting from the consolidation of PEPSA and PELSA in our 2003
financial results.

Monetary and exchange variation on monetary assets and liabilities, net

Monetary and exchange variation on monetary assets and liabilities, net
registered a gain of U.S.$ 509 million for 2003, as compared to a loss of U.S.$
2,068 million for 2002. Approximately 90% of our long-term indebtedness was
denominated in foreign currencies during each of 2003 and 2002. The fluctuation
in monetary and exchange variation on monetary assets and liabilities, net was
primarily attributable to the effect of the 18.2% appreciation of the Real
against the U.S. dollar during 2003, as compared to a 52.3% depreciation of the
Real against the U.S. dollar during 2002.

Employee benefit expense

Employee benefit expense consists of financial costs associated with expected
pension and health care costs. Our employee benefit expense increased 31.9% to
U.S.$ 595 million for 2003, as compared to U.S.$ 451 million for 2002. This rise
in costs was attributable to an increase of U.S.$ 166 million from the annual
actuarial calculation of our pension and health care plan liability. The
increase was partially offset by the effect of the 5.2% decrease in the value of
the Real against the U.S. dollar in 2003, as compared to 2002.

Other taxes

Other taxes, consisting of miscellaneous value-added, transaction and sales
taxes, decreased 7.5% to U.S.$ 333 million for 2003, as compared to U.S.$ 360
million for 2002. This decrease was primarily attributable to the 5.2% decrease
in the value of the Real against the U.S. dollar in 2003, as compared to 2002,
and the decrease of U.S.$ 61 million in the PASEP/COFINS taxes payable in
respect of foreign exchange gains on assets, resulting from transactions with
affiliates with assets denominated in foreign currencies.

Other expenses, net

Other expenses, net are primarily composed of gains and losses recorded on sales
of fixed assets, general advertising and marketing expenses and certain
nonrecurring charges. Other expenses, net for 2003 increased to an expense of
U.S.$ 1,026 million, as compared to an expense of U.S.$ 857 million for 2002.

The most significant charges for 2003 were:

o    a U.S.$ 183 million loss related to our investments in certain
     thermoelectric power plants resulting from our contractual obligations with
     certain power plants to cover losses when decreased demand for power and
     electricity lead to lower prices;

o    a U.S.$ 198 million expense for general advertising and marketing expenses
     unrelated to direct revenues;

o    a U.S.$ 173 million expense for unscheduled stoppages of plant and
     equipment;

o    a U.S.$ 130 million expense for legal liability and contingencies related
     to pending lawsuits. Please see Note 22 to our consolidated financial
     statements;

o    a U.S.$ 114 million expense for a lower of cost or market adjustment with
     respect to turbines we originally expected to use in connection with our
     thermoelectric projects, but which we no longer intend to use for such
     projects;

o    a U.S.$ 97 million provision for expected losses on the sale of property,
     plant and equipment related to off-shore production;

o    a U.S.$ 56 million increase in contractual losses from compliance with our
     ship or pay commitments with respect to our investments in the OCP pipeline
     in Ecuador; and

o    a U.S.$ 55 million provision for tax assessments received from the
     Instituto Nacional de Seguridade Social (National Social Security
     Institute, or INSS). Please see Note 22 to our consolidated financial
     statements.

The most significant charges for 2002 were:

o    a U.S.$ 459 million loss related to our investments in certain
     thermoelectric power plants;

o    a U.S.$ 111 million expense for unscheduled stoppages of plant and
     equipment;

o    a U.S.$ 105 million provision for notifications of tax assessments received
     from the INSS;

o    a U.S.$ 96 million expense for general advertising and marketing expenses
     unrelated to direct revenues; and

o    a U.S.$ 29 million expense for regularization of the Petroleum and Alcohol
     Account.

Income tax (expense) benefit

Income before income taxes, minority interest and accounting changes increased
to U.S.$ 8,773 million for 2003, as compared to U.S.$ 3,232 million for 2002. As
a result, we recorded an income tax expense of U.S.$ 2,663 million for 2003, as
compared to an expense of U.S.$ 1,153 million for 2002.

The reconciliation between the tax calculated based upon statutory tax rates to
income tax expense and effective rates is discussed in Note 4 to our
consolidated financial statements as of December 31, 2003.

Cumulative effect of change in accounting principle

In the first quarter of 2003, we registered a gain of U.S.$ 697 million (net of
U.S.$ 359 million of taxes) resulting from the adoption of SFAS No. 143 -
Accounting for Asset Retirement Obligations. The adjustment was due to the
difference in the method of accruing site restoration costs under SFAS 143, as
compared with the method required by SFAS 19 - Financial Accounting and
Reporting by Oil and Gas Producing Companies. Under SFAS 19, we had accrued
upstream site restoration costs ratably over the productive lives of the assets.
Under SFAS 143, we record the fair value of asset retirement obligations as
liabilities on a discounted basis when they are incurred, which is typically at
the time the related assets are installed. The income adjustment described above
resulted from reversing the higher liability accumulated under SFAS 19 in order
to adjust it to a lower present value amount resulting from transition to SFAS
143. Please see Note 3 to our consolidated financial statements as of December
31, 2003.









                         INCREASE OF AUTHORIZED CAPITAL


On June 10, 2002, our shareholders approved a change in our by-laws authorizing
a capital increase of up to R$ 30 billion (U.S.$ 10.4 billion) by deliberation
of the Board of Directors through the issuance of up to 200 million shares.

The General Extraordinary Shareholders Meeting, held in conjunction with the
General Ordinary Meeting on March 29, 2004, approved an increase in authorized
capital from R$ 30 billion (U.S.$ 10.4 billion) to R$ 60 billion (U.S.$ 20.8
billion).





                        THERMOELECTRIC PLANT OBLIGATIONS

As a result of adopting FIN 46 at December 31, 2003, we now consolidate six
thermoelectric plants. Previously, three of these thermoelectric plants were
accounted for as capital leases, and therefore, their consolidation did not have
a material impact on our financial condition. For the other three thermoelectric
plants, we were deemed the primary beneficiary because of contractual
obligations concerning third party interests that required us to bear energy
market risk.

The consolidation of the three thermoelectrics formerly treated as capital
leases resulted in U.S.$ 375 million being reclassified from capital lease
obligations to long-term debt obligations. The impact of changing the
obligations related to these three plants from the minimum value of future lease
payments to the debt outstanding with third party lenders was immaterial. At
December 31, 2003, the consolidation of the three thermoelectrics previously
accounted for as contractual obligations concerning third party interests
resulted in an increase to assets and long-term obligations of U.S.$ 1,142
million.

At December 31, 2002, we had commitments with thermoelectric plants related to
(a) the supply of natural gas for the production of energy and the purchase of
all or a portion of the energy generated by these plants and (b) commitments to
reimburse certain allocations as defined by the Consortium Agreements. At
December 31, 2002, the recorded provision for future losses related to our
energy business amounted to U.S.$ 205 million. On May 7, 2003, the Executive
Board authorized an increase in the above-mentioned accounting provision of an
additional U.S.$ 205 million, primarily due to depressed sales of energy
following the energy rationing program and the lack of a well-defined regulatory
framework for the energy sector. The provisions for future losses made in 2002
and early 2003, totaling U.S.$ 410 million, were utilized during the course of
2003.

At December 31, 2003, as a result of the adoption of FIN 46 and the
consolidation of the six thermoelectric plants, it is no longer necessary to
recognize any liability for future payments expected to be made under the
agreements with the sponsors of these six thermoelectric plants. We will now
recognize any losses from operations of these six thermoelectric plants if and
when they occur.

The following chart summarizes amounts recognized in connection with our
participation in the Brazilian Government's Thermoelectric Priority Energy
Program for 2003 and 2002:

(1) As a result of the adoption of FIN 46 in our December 31, 2003 annual
financial statements, no provision for losses relating to thermoelectric power
plants to be incurred in 2004 was booked.








ACQUISITION OF AN INTEREST IN PETROBRAS ENERGIA PARTICIPACIONES S.A.- PEPSA
(FORMERLY KNOWN AS PEREZ COMPANC S.A.) AND PETROLERA ENTRE LOMAS S.A. - PELSA
(FORMERLY KNOWN AS PETROLERA PEREZ COMPANC S.A.)


On October 17, 2002, we, through an indirectly controlled company, signed an
agreement to purchase 58.62% of the capital of PEPSA and 39.67% of the capital
of PELSA which together with PEPSA's interests brings our ownership interest in
PELSA to 50.73%. On May 13, 2003, the Argentine antitrust authorities approved
these purchases.

The acquisitions of PEPSA and PELSA were recorded using the purchase method of
accounting.

Because the statements of income of PEPSA and PELSA for the period from May 13,
2003 to May 31, 2003 are not available, we have consolidated the statements of
income of PEPSA and PELSA as of June 1, 2003. We believe that the inclusion of
the statements of income of PEPSA and PELSA for the period from May 13, 2003 to
May 31, 2003 would not have materially affected our net income for 2003.

The following unaudited pro forma summary financial information presents the
consolidated results of operations as if the acquisition of PEPSA and PELSA had
occurred at the beginning of the periods presented:

(1)   At December 31, 2003, the international business segment includes the
      Argentine operations of Petrolera Santa Fe (acquired in October 2002),
      PEPSA and PELSA (both acquired in May 2003).





Exploration and Production

Our exploration and production segment includes our exploration, development and
production activities in Brazil, as well as sales of crude oil and natural gas
in the domestic and foreign markets.

Consolidated net income for our exploration and production segment increased
61.3% to U.S.$ 5,504 million for 2003, as compared to U.S.$ 3,413 million for
2002. This increase was primarily attributable to:

o    a U.S.$ 2,652 million increase in net operating revenues as a result of the
     increase in the price of crude oil in the international markets and a 2.7%
     increase in production of crude oil, NGL and natural gas;

o    the cumulative effect of a change in accounting principle related to future
     liabilities for asset retirement obligations, which led to an increase in
     our net income of U.S.$ 697 million, net of taxes;

o    a U.S.$ 626 million reduction in financial expenses, net primarily related
     to the effects of the 18.2% appreciation of the Real against the U.S.
     dollar during 2003, as compared to a 52.3% depreciation of the Real against
     the U.S. dollar during 2002; and

o    a U.S.$ 423 million reduction in depreciation, depletion and amortization
     primarily attributable to the 5.2% decrease in the value of the Real
     against the U.S. dollar in 2003, as compared to 2002, as well as the
     beneficial effect of adopting SFAS 143, as described in Note 3 to our
     consolidated financial statements.

These effects were partially offset by a U.S.$ 1,325 million increase in cost of
sales, primarily composed of:

o    an increase of approximately U.S.$ 152 million in costs related to crude
     oil, natural gas and NGL volumes sold or transferred to other business
     segments; and

o    an increase of approximately U.S.$ 1,067 million in taxes and charges
     imposed by the Brazilian government.

Supply

Our supply segment includes refining, logistic, transportation and the purchase
of oil, as well as the purchase and sale of oil products and fuel alcohol.
Additionally, this segment includes the petrochemical and fertilizers division,
which includes investments in domestic petrochemical companies and our two
domestic fertilizer plants.

Consolidated net income for our supply segment increased to U.S.$ 1,738 million
for 2003, as compared to U.S.$ 711 million for 2002.

This increase was primarily attributable to an increase of U.S.$ 6,377 million
in net operating revenues. This increase in net operating revenues was primarily
due to the alignment in 2003 of prices of certain oil products in the Brazilian
market with international market prices of such products at the end of 2002 and
to our refineries' increased processing of higher value added products.

This increase was partially offset by the increase of U.S.$ 4,702 million in
cost of sales, mainly due to the increase in import prices of crude oil and oil
products and increases in prices of products transferred from other segments,
notwithstanding the following facts:

o    the 6.2% decrease in volume of sales within the supply segment as a result
     of a decrease in Brazilian consumer demand;

o    the higher participation of domestic crude oil in the total feedstock
     processed (80% in 2003 and 79% in 2002); and

o    the streamlining of logistical expenses, mainly freight costs.

Gas and Energy

Our gas and energy segment consists principally of the purchase and sale and
transportation of natural gas produced in or imported into Brazil. Additionally,
this segment includes our domestic electric energy purchase and sale activities
as well as investments in domestic natural gas transportation companies, state
owned natural gas distributors and thermoelectric companies.

Our gas and energy segment registered a net loss of U.S.$ 196 million for 2003,
as compared to a net loss of U.S.$ 190 million for 2002. This result was
affected primarily by the following factors:

o    a U.S.$ 467 million increase in losses with minority interest, primarily
     related to the effects on the net loss of Transportadora Brasileira
     Gasoduto Bolivia-Brasil S.A. - TBG related to the 18.2% appreciation of the
     Real against the U.S. dollar during 2003, as compared to a 52.3%
     depreciation of the Real against the U.S. dollar during 2002;

o    a U.S.$ 451 million increase in cost of sales primarily due to a 13.5%
     increase in the volume of natural gas sold and to the start of operations
     of some thermoelectric power plants at the end of 2003;

o    a U.S.$ 114 million expense for a lower of cost or market adjustment in gas
     turbines;

o    a U.S.$ 562 million increase in net operating revenues primarily due to the
     increase of natural gas prices and to the 13.5% increase in the volume of
     natural gas sold;

o    a U.S.$ 183 million decrease in losses related to our investments in
     thermoelectric power plants; and

o    a U.S.$ 150 million increase in the results of non-consolidated companies,
     primarily due to gains from our investments in natural gas distribution
     companies and the adoption of FIN 46, resulting in the consolidation of
     three thermoelectric power plants for which we recorded losses in equity in
     2002.

International

The international segment represents our international activities conducted in
13 countries, which include Exploration and Production, Supply, Distribution and
Gas and Energy.

Consolidated net income for our international segment increased to a net gain of
U.S.$ 101 million for 2003, as compared to a net loss of U.S.$ 114 million for
2002. This increase was primarily attributable to:

o    a U.S.$ 1,342 million increase in net operating revenues resulting from the
     increase of oil products prices in the international markets and an
     increase in the volume of sales conducted by PEPSA and PELSA; ando

o    a U.S.$ 157 million increase in the results of non-consolidated companies,
     primarily due to a gain of U.S.$ 59 million in our equity investments in
     Compania Mega during 2003, as compared to a loss of U.S.$ 95 million during
     2002.

This increase was partially offset by the following factors, primarily
attributable to PEPSA and PELSA's operations:

o    a U.S.$ 586 million increase in cost of sales;

o    a U.S.$ 182 million increase in depreciation, depletion and amortization;

o    a U.S.$ 160 million increase in debt expense net;

o    a U.S.$ 118 million increase in selling, general and administrative
     expenses;

o    a U.S.$ 69 million increase in exploration, including exploratory dry holes
     and impairment; and

o    a U.S.$ 56 million increase in contractual losses from compliance with our
     ship or pay commitments with respect to our investments in the OCP pipeline
     in Ecuador.

Distribution

Our distribution segment represents the oil product and fuel alcohol
distribution activities conducted by our majority owned subsidiary, Petrobras
Distribuidora S.A. - BR in Brazil.

Consolidated net income for our distribution segment increased 51.6% to U.S.$
138 million for 2003, as compared to U.S.$ 91 million for 2002. This increase
was primarily attributable to a U.S.$ 1,453 million increase in net operating
revenues as a result of the increase of oil products sales prices to refineries
(we increased these sales prices in order to maintain our gross margin).

This effect was partially offset by a 6.0% decrease in the volume of oil
products sold within the distribution segment in 2003 as compared to the volume
sold in 2002; the decrease in our market share in the Brazilian oil products
market to 31.5% for 2003, as compared to 32.9% for 2002; and the increase of
U.S.$ 1,396 million in our cost of sales in 2003, reflecting the increase in
prices of oil products purchased from refineries.

Corporate

Our corporate segment includes those activities not attributable to other
segments, including corporate financial management, overhead related to central
administration and other expenses, including actuarial expenses related to
pension and health care plans.

Consolidated loss for the units that make up our corporate segment decreased
61.3% to a net loss of U.S.$ 496 million during 2003, as compared to a net loss
of U.S.$ 1,280 million during 2002. This decrease was primarily attributable to
the reduction of U.S.$ 1,268 million in financial expenses net, primarily
attributable to the effect of the 18.2% appreciation of the Real against the
U.S. dollar during 2003, as compared to a 52.3% depreciation of the Real against
the U.S. dollar during 2002.

This decrease was partially offset by:

o    a U.S.$ 160 million increase in general and administrative expenses,
     primarily due to higher expenses related to technical consulting services
     in non-core general and administrative activities and employee training
     expenses;

o    a U.S.$ 160 million increase in expenses related to employee benefits; and

o    a U.S.$ 73 million increase in expenses related to institutional relations
     and cultural projects.








                         LIQUIDITY AND CAPITAL RESOURCES

Overview

Our principal uses of funds are for capital expenditures, dividend payments and
repayment of debt. We have historically met these requirements with internally
generated funds, short-term debt, long-term debt, project financings and sale
and lease back agreements. We believe these sources of funds, together with our
strong cash and cash equivalents on hand, will continue to allow us to meet our
currently anticipated capital requirements. In 2004, our major cash needs
include announced capital expenditures of U.S.$ 5,066 million.

Financing Strategy

The objective of our financing strategy is to help us achieve the targets set
forth in our Strategic Plan, which provides for capital expenditures of U.S.$
27.1 billion from 2004 to 2007. We also aim to increase the average life of our
debt portfolio and reduce our cost of capital through a variety of medium and
long-term financing arrangements, including supplier financing, project
financing, bank financing, securitizations and the issuances of debt and equity
securities.

To that end, we took advantage of market conditions in 2003 to extend our
maturity profile and capture decreased financing costs. We went from issuing a
5-year note bearing an interest rate of 9.0% in the beginning of the year to
issuing a 15-year note with an 8.375% coupon on December 10, 2003. At the time
of the issuance, the 15-year maturity was a record for Brazilian corporations.

Government Regulation

The Ministry of Planning, Budget and Management controls the total amount of
medium and long-term debt that we and our Brazilian subsidiaries are allowed to
incur through the annual budget approval process (Plano de Dispendio Global, or
PDG). Before issuing medium and long-term debt, we and our Brazilian
subsidiaries must also obtain the approval of the National Treasury shortly
before issuance.

In accordance with Senate Resolution N(0) 96/89 the level of our borrowings is
subject to an annual maximum amount, exclusive of certain permitted commercial
obligations, based on shareholders' equity, debt service expense and other
factors as of the prior year and subject to certain ongoing quarterly
adjustments. For 2003, the maximum level of debt that we and our Brazilian
subsidiaries could incur was set at U.S.$ 932 million. The maximum level was set
at U.S.$ 824 million for 2002 and U.S.$ 1,211 million for 2001.

All of the foreign currency denominated debt of we and 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. 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 budget amount for
any year also require approval from the Brazilian Senate.

Sources of Funds

Our Cash Flow

At December 31, 2003, we had cash and cash equivalents of U.S.$ 9,610 million
compared to U.S.$ 3,301 million at December 31, 2002. This increase in cash was
a result of:

o    the increase in our net operating revenues during 2003, which was primarily
     driven by the increase in crude oil prices;

o    the proceeds from the issuance of greater amounts of debt in the
     international capital markets; and

o    the adoption of FIN 46 which resulted in an increase in cash and cash
     equivalents of U.S.$ 1,049 million.

Operating activities provided net cash flows of U.S.$ 8,569 million in 2003, as
compared to U.S.$ 6,287 million in 2002. This increase was due primarily to a
36.2% increase in net operating revenues.

Net cash used in investing activities decreased to U.S.$ 5,519 million in 2003,
as compared to U.S.$ 6,656 million in 2002. This decrease was due primarily to
adoption of FIN 46.

Financing activities provided net cash flows of U.S.$ 2,376 million for 2003, as
compared to U.S.$ 1,614 million in net cash used in 2002. This increase was due
primarily to net issuances of short and long-term debt, which was partially
offset by an increase in our repayments of short and long-term debt.

Short-Term Debt

Our outstanding short-term debt serves mainly to support our imports of crude
oil and oil products, and is provided almost completely by international banks
and under our commercial paper program. At December 31, 2003, our short-term
debt (excluding current portions of long-term obligations) increased to U.S.$
1,329 million as compared to U.S.$ 671 million at December 31, 2002. This
increase was due to the inclusion of PEPSA's short term debt in our consolidated
balance sheets and our increased use of short-term credit facilities. Our
short-term debt is denominated principally in U.S. dollars.

Long-Term Debt

Our total outstanding consolidated long-term debt consists primarily of the
issuance of securities in the international capital markets and debentures in
the domestic capital markets and amounts outstanding under facilities guaranteed
by export credit agencies and multilateral agencies, as well as financing from
the Banco Nacional de Desenvolvimento Economico e Social (the National Bank for
Economic and Social Development, or BNDES) and other financial institutions.
Outstanding long-term debt, plus the current portion of our long-term debt,
totaled U.S.$ 13,033 million at December 31, 2003, as compared to U.S.$ 7,714
million at December 31, 2002. Included in these figures at December 31, 2003 are
the following international debt issuances:

(4) Issued by PIFCo on October 17, 2002 in connection with our acquisition of
    PEPSA.
(5) The Global Step-up Notes bear interest from March 31, 2003 at a
    rate of 9.00 % per year until
    April 1, 2006 and at rate of 12.375% per year thereafter, with interest

(7) Issued by PEPSA on October 31, 2003 to cancel existing liabilities.

On March 31, 2003, PIFCo issued U.S.$400 million of 9.00% Global Step-Up Notes
due 2008. These notes bear interest from March 31, 2003 at the rate of 9.00% per
year until April 1, 2006 and at a rate of 12.375% thereafter. This transaction
represented our first issuance under our U.S.$ 8 billion universal shelf
registration statement filed with the SEC in July 2002.

On May 21, 2003, Petrobras Finance Ltd., a subsidiary of PIFCo, received U.S.$
550 million in 6.436% Senior Trust Certificates due 2015, and U.S.$ 200 million
in 3.748% Senior Trust Certificates due 2013 in connection with our exports
prepayment program. On July 2, 2003, PIFCo issued Global Notes in an aggregate
principal amount of U.S.$ 500 million due July 2013. The notes bear interest at
the rate of 9.125% per annum, payable semiannually. On September 18, 2003, PIFCo
issued an additional U.S.$ 250 million in Global Notes, which form a single
fungible series with its U.S.$ 500 million Global Notes due July 2013. On
December 10, 2003, PIFCo issued U.S.$ 750 million of 8.375% Global Notes due
2018.

We describe the average interest rates on our long-term debt in Note 12 to our
consolidated financial statements.

In addition to issuing foreign currency denominated debt in the international
capital markets, we have historically issued Real-denominated debentures in the
local capital markets. These debentures are floating-rate obligations, and the
coupon is based on an index plus a fixed spread.

We did not issue any Real-denominated debentures in 2003. In 2002, we issued R$
1,525 million (U.S.$ 432 million) in Real-denominated debentures. Outstanding
debentures totaled U.S.$ 928 million at December 31, 2003, as compared to U.S.$
688 million at December 31, 2002.

Project Finance

Since 1997, we have utilized project financings to provide capital for our large
exploration and production and related projects, including some natural gas
processing and transportation systems. All of these projects, and their related
debt obligations, are on-balance sheet and accounted for under the line item
"Project Financings". The special purpose companies established to finance these
projects are consolidated in accordance with FIN 46. Under the contractual
arrangements, we are responsible for completing the development of the oil and
gas fields, operating the fields, paying all operating expenses relating to the
projects and remitting a portion of the net proceeds generated from the fields
to fund the special purpose companies' debt and return on equity payments. At
the end of each financing project, we have the option to purchase the project
assets from the special purpose company or, in some cases, acquire control over
the special purpose company itself.

During 2003, we made capital expenditures of U.S.$ 1,316 million (20.1% of our
total capital expenditures) in connection with exploration and development
projects in the Campos Basin, which are being financed through project
financings.





The following summarizes the liabilities related to the projects that were in
progress at December 31, 2003 and 2002:

At December 31, 2003, we had amounts invested abroad in an exclusive investment
fund that held debt securities of some of our group companies in the amount of
U.S.$ 713 million related to project financings. These securities are considered
to be extinguished, and thus the related amounts, together with applicable
interest have been removed from the presentation of project finance.

At December 31, 2003, the long-term portion of project financings becomes due in
the following years:

                                               U.S.$ million

Off Balance Sheet Arrangements

As noted above, all of our project financings are on-balance sheet. At December
31, 2003, we had no 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.


Net Debt

Our net debt totaled U.S.$ 11,980 million at December 31, 2003, a 6.7% increase
from net debt of U.S.$ 11,229 million at December 31, 2002, primarily due to the
inclusion of PEPSA's and PELSA's net debt of U.S.$ 1,788 million in our net debt
totals and our issuance of U.S.$ 5,400 million in long-term debt in the
international capital markets during 2003. These increases were partially offset
by increase in cash and cash equivalents as a result of the increase in net cash
provided by operating activities. For a reconciliation of net debt to total
long-term debt, please see page 3.






Uses of Funds

Budgeted Capital expenditures

In 2003, we continued to prioritize capital expenditures for the development of
crude oil and natural gas production projects through internal investments and
through structured undertakings with partners. We invested a total of U.S.$
6,551 million in 2003, a 33.4% increase from our investments in 2002.

Our increased capital expenditures in 2003 were primarily directed towards
increasing our production capabilities in the Campos Basin, modernizing our
refineries, expanding our pipeline transportation and distribution systems and,
to a lesser extent, investing in energy and gas related activities, including
investments in thermoelectric power plants. We spent U.S.$ 3,658 million (55.8%)
in 2003 in our domestic exploration and production activities, which includes
our exploration and production segment and our project financings.

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 2003 and 2002:

Our Strategic Plan contemplates total budgeted capital expenditures of U.S.$
27.1 billion in the period from 2004 through 2007, approximately U.S.$ 22.7
billion of which will be directed towards our activities in Brazil, while U.S.$
4.4 billion will be directed to our activities abroad. We expect that the
majority of our capital expenditures from 2004 through 2007, approximately U.S.$
18.0 billion, will be directed towards exploration and production, of which
U.S.$ 14.2 billion are designated for our activities in Brazil.

We are in the process of reviewing our Strategic Plan and intend to release a
new version in April 2004 that could revise our forecasts for capital
expenditures for 2004-2007.

Dividends

Based on our financial results and cash available for distribution, the General
Shareholders' Meeting held on March 29, 2004 approved a distribution of
dividends of U.S.$ 1,955 million (U.S.$ 1.78 per share). The U.S.$ 1,127 million
already distributed to shareholders on February 13, 2004 in the form of interest
on capital was deducted from this amount. The dividend includes an additional
U.S.$ 436 million of interest on capital.

Risk Management Activities

We are exposed to a number of market risks arising in the normal course of
business. We may use derivative and non-derivative instruments to manage these
risks. For a description of our risk management activities, see Note 23 to our
consolidated financial statements.

Contractual Obligations

The following table summarizes our contractual obligations at December 31, 2003.
The table does not include employee postretirement benefits, deferred income tax
or trade accounts payable.

                         REPORT OF INDEPENDENT AUDITORS

To the Board of Directors and Shareholders of
PETROLEO BRASILEIRO S.A. - PETROBRAS:

We have audited the accompanying consolidated balance sheet of PETROLEO
BRASILEIRO S.A. - PETROBRAS and subsidiaries as of December 31, 2003, and the
related consolidated statements of income, shareholders' equity, and cash flows
for the year then ended. These financial statements are the responsibility of
the Company's management. Our responsibility is to express an opinion on these
financial statements based on our audit. The financial statements of Petroleo
Brasileiro S.A. - PETROBRAS as of December 31, 2002 and for the years ended
December 31, 2002 and 2001, were audited by other auditors whose report dated
February 13, 2003, expressed an unqualified opinion on those statements.

We conducted our audit in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audit provides a
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of PETROLEO
BRASILEIRO S.A. - PETROBRAS and subsidiaries at December 31, 2003, and the
consolidated results of their operations and their cash flows for the year then
ended in conformity with accounting principles generally accepted in the United
States of America.

Effective January 1, 2003, the Company adopted SFAS No. 143 - Accounting for
Asset Retirement Obligations ("SFAS 143"). Additionally, at December 31, 2003
the Company adopted FIN 46 "Consolidation of Variable Interest Entities" as
discussed in Note 3.

PETROLEO BRASILEIRO S.A. - PETROBRAS
AND SUBSIDIARIES

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
Expressed in Millions of United States Dollars
(except when specifically indicated)
--------------------------------------------------------------------------------

1.   The Company and its operations

     PETROLEO BRASILEIRO S.A. - PETROBRAS is Brazil's national oil company and,
     directly or through its subsidiaries (collectively, "PETROBRAS" or the
     "Company"), is engaged in the exploration, exploitation and production of
     oil from reservoir wells, shale and other rocks, and in the refining,
     processing, trade and transport of oil and oil derivatives, natural gas and
     other fluid hydrocarbons, in addition to other energy related activities.
     Additionally, PETROBRAS may promote the research, development, production,
     transport, distribution and marketing of all sectors of energy, as well as
     other related or similar activities.

     PETROBRAS was incorporated under Law No. 2,004 on October 3, 1953. Until
     November of 1995, PETROBRAS was the exclusive agent of the Brazilian
     Federal Government (the "Federal Government") for purposes of exploiting
     the Federal Government's constitutional and statutory control over
     activities involving exploration, production, refining, distribution,
     import, export, marketing and transportation of hydrocarbons and oil
     products in Brazil and its continental waters. When adopted in 1953, the
     relevant provisions of the Brazilian constitution and statutory law gave
     the Federal Government a monopoly in these areas subject only to the right
     of companies then engaged in oil refining and the distribution of oil and
     oil products to continue those activities in Brazil. Therefore, except for
     limited competition from those companies in their grandfathered activities,
     PETROBRAS had a monopoly over its businesses for approximately 42 years. As
     a result of a change in the Brazilian constitution in November of 1995, and
     the subsequent and ongoing implementation of that change, PETROBRAS has
     ceased to be the Federal Government's exclusive agent in Brazil's
     hydrocarbons sector and up to 2001 had been operating in an environment of
     gradual deregulation and increasing competition.

     In accordance with Law No. 9,478 ("Petroleum Law") and Law No. 9,990, dated
     August 6, 1997 and July 21, 2000, respectively, the fuel market in Brazil
     was totally liberalized beginning January 1, 2002 permitting other
     companies to produce and sell on the domestic market, and also to import
     and export oil products.

     The Company also has oil and gas operations in international locations,
     with the most significant international operations being in other Latin
     American countries.

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, environmental obligations, depreciation, depletion
     and amortization, abandonment costs, 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.

     (a)  Basis of financial statements preparation

          The accompanying consolidated financial statements of PETROLEO
          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 Brazilian accounting practice as applied by PETROBRAS in
          its statutory financial statements prepared in accordance with
          Brazilian Corporate Law and regulations promulgated by the Brazilian
          Securities Commission (CVM).

          The U.S. dollar amounts for the years presented have been translated
          from the Brazilian Real amounts in accordance with Statement of
          Financial Accounting Standards SFAS No. 52 - Foreign Currency
          Translation ("SFAS 52") 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 is the Brazilian Real.

          The Company has translated all assets and liabilities into U.S.
          dollars at the current exchange rate (R$ 2.8892 and R$ 3.5333 to US$
          1.00 at December 31, 2003 and 2002, 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/ (loss) in the
          amount of US$ 2,856 in 2003 (2002 - US$ (5,452) and 2001 - US$
          (2,695)) resulting from this remeasurement process was excluded from
          income and presented as a cumulative translation adjustment ("CTA")
          within Other Comprehensive Income in the statement of changes in
          shareholders' equity.

     (b)  Basis 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 management control, or (b) the Company has
          determined itself to be the primary beneficiary of a variable interest
          entity in accordance with FIN 46 (Note 3(b)). Intercompany accounts
          and transactions are eliminated.

          The following majority-owned subsidiaries and variable interest
          entities are consolidated:

               Formerly were special purpose entities formed in connection with
               project finance transactions.

          (3)  Consolidated according to FIN 46, commencing December 31, 2003.
               Formerly were accounted for as capital leases pursuant to SFAS
               13. See Notes 15 and 16.

          (4)  Consolidated  according to FIN 46, commencing  December 31, 2003.
               Formerly were not consolidated to PETROBRAS financial statements,
               see Note 16.

     (c)  Cash equivalents

          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)  Accounts receivable

          Accounts receivable is stated at estimated realizable values. An
          allowance for doubtful accounts is provided in an amount considered by
          management to be sufficient to meet probable future losses related to
          uncollectible accounts.

     (e)  Inventories

          Inventories are stated as follows:

          o    Raw materials comprise principally crude oil inventories, which
               are stated at the lower of average cost or market value.

          o    Oil products and fuel alcohol are stated, respectively, at
               average refining and purchase cost, adjusted when applicable to
               their realizable value.

          o    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. 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)  Government and marketable securities

          The Company holds National Treasury Bonds "Series B" (NTN-B) issued by
          the Federal Government which are accounted for as available-for-sale
          securities in accordance with SFAS No. 115 - Accounting for Certain
          Investments in Debt and Equity Securities ("SFAS 115"). The Company
          has maintained junior trust notes received in connection with the
          structured finance program as held-to-maturity, and additionally has
          certain available-for-sale investments in companies with publicly
          traded shares.


     (h)  Property, plant and equipment

          o    Costs incurred in oil and gas producing activities

               The successful efforts method of accounting is used for oil and
               gas exploration, development and production activities.

          o    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.

          o    Exploratory costs

               Exploratory wells that find oil and gas in an area requiring a
               major capital expenditure before production can begin 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.

          o    Development costs

               Costs of development wells including dry holes, platforms, well
               equipment and attendant production facilities are capitalized.

          o    Production costs

               Costs incurred with producing wells are expensed as incurred.

          o    Abandonment costs

               Through December 31, 2002, the Company recorded abandonment costs
               in accordance with SFAS No. 19 - Financial Accounting and
               Reporting by Oil and Gas Production Companies ("SFAS 19"). Under
               SFAS 19, the estimated costs of dismantlement and removal of oil
               and gas related facilities are accrued over the properties'
               production lives using the unit-of-production method and
               recognized as accumulated depreciation, depletion and
               amortization as the expense is recorded. Effective January 1,
               2003, the Company adopted SFAS 143 for abandonment costs (see
               Note 3(a) for information related to the new accounting policy
               for abandonment costs commencing from January 1, 2003).

          o    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
               reserves produced. Leased production platforms 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 are recorded using the
               unit-of-production method applied on a field by field basis as a
               ratio of proved developed reserves produced. Prior to January 1,
               2003, estimated dismantlement, restoration and abandonment costs
               and estimated salvage values are taken into account in
               determining amortization and depreciation provisions.


               Other plant and equipment are depreciated on a straight-line
               basis over the following estimated useful lives:

                   Building and improvements                    25 years
                   Equipment and other assets                 3-25 years
                   Platforms                                 10-25 years
                   Pipelines                                    30 years

          o    Impairment

               In accordance with SFAS No. 144 - Impairment of Long-Lived Assets
               ("SFAS 144"), 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.

          o    Maintenance and repairs

               The actual costs of major maintenance, including turnarounds at
               refineries and vessels, as well as other expenditures for
               maintenance and repairs, are expensed as incurred.

          o    Capitalized interest

               Interest is capitalized in accordance with SFAS No. 34 -
               Capitalization of Interest Cost ("SFAS 34"). 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
               of the related assets. Interest is capitalized at the Company's
               weighted average cost of borrowings.

     (i)  Revenues, costs and expenses

          Revenues from sales of crude oil and oil products, petrochemical
          products and others are recognized on an accrual basis when the title
          is transferred to the customer. Revenues from sales of natural gas are
          accounted for when the natural gas is transferred to the customer.
          Subsequent adjustments to revenue based on production sharing
          agreements or volumetric delivery differences are not significant.
          Costs and expenses are accounted for on an accrual basis.


     (j)  Income taxes

          The Company accounts for income taxes in accordance with SFAS No. 109
          - Accounting for Income Taxes ("SFAS 109"), which requires an asset
          and liability approach to recording current and deferred taxes. The
          effects of differences between the tax bases of assets and liabilities
          and the amounts recognized in the financial statements have been
          treated as temporary differences for the purpose of recording deferred
          income taxes.

          PETROBRAS 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 that will not be recovered
          against future taxable income using a "more likely than not"
          criterion.

     (k)  Employee postretirement benefits

          The Company sponsors a contributory defined-benefit pension plan
          covering substantially all of its employees, which is accounted for by
          the Company in accordance with SFAS No. 87 - Employers' Accounting for
          Pensions ("SFAS 87").

          In addition, the Company provides certain health care benefits for
          retired employees and its dependents. The cost of such benefits is
          recognized in accordance with SFAS No. 106 - Postretirement Benefits
          Other Than Pensions ("SFAS 106").

          The Company also contributes to the national pension, 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.

     (l)  Environmental and remediation costs

          Environmental costs relating to current operations are expensed or
          capitalized, as appropriate, depending on whether such costs are
          expected to provide future economic benefits. Liabilities are
          recognized when the costs are considered probable and can be
          reasonably estimated.

     (m)  Accounting for the effect of Federal Government regulation

          As provided in the Petroleum Law, the fuel market in Brazil was
          totally liberalized as of January 1, 2002 permitting other companies
          to produce and sell on the domestic market and, also, import and
          export oil products. Additionally, as of January 1, 2002, PETROBRAS is
          no longer required to charge the prices established by the Federal
          Government on the sale of oil products, and the realization price is
          no longer established by a formula adjusted to the international
          market. Therefore the specific parcel price (Parcela de Preco
          Especifico - PPE) is no longer collected.

          Considering the liberation of the market and current legislation, as
          from January 1, 2002, the Petroleum and Alcohol Account will no longer
          be used to reimburse expenses related to the supply of oil products
          and fuel alcohol to PETROBRAS and third parties. The movements in the
          account during 2002 relate only to (i) payments and adjustments
          mandated by the Agencia Nacional do Petroleo - ANP ("ANP") with no
          impact on the income statement and (ii) adjustments resulting from the
          audit of the account by the ANP.

          The impact of Federal Government regulation on the Company's balance
          sheet and operating structure has been recorded in the Petroleum and
          Alcohol Account as of, and for the years ended, December 31, 2003,
          2002 and 2001 (see Note 11). The impact of this regulation is recorded
          in the income statement to correspond with underlying transactions
          when compliance with applicable law has occurred and collection is
          reasonably assured.

          The Contribuicao de Intervencao no Dominio Economico (Contribution of
          Intervention in the Economic Domain Charge - CIDE) on the importation
          and sale of fuels was established by Law No. 10,336 dated December 19,
          2001.

          The CIDE is a per-transaction payment to the Brazilian Government
          required to be made by producers, blenders and importers upon sales
          and purchases of specified oil and fuel products at a set amount for
          different products based on the unit of measurement typically used for
          such products.

          The Company's income statement for the year ended December 31, 2001
          were impacted by Federal Government regulation in the amount of US$
          1,066.

     (n)  Compensated absences

          The liability for future compensation of employees for vacations is
          accrued as earned.

     (o)  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. The preferred shares participate in dividends and
          undistributed earnings with the common shares at a predetermined
          formula. Such formula allocates the net income, as if all of the net
          income for each year had been distributed, first to the preferred
          shares in an amount equal to the preferred shares' priority minimum
          annual dividend of the higher of 3% of their shareholders equity or 5%
          of their paid-in capital as stated in the statutory accounting
          records, then to common shares in an amount equal to the preferred
          shares' priority dividend on a per share basis and any remaining net
          income is allocated equally to the common and preferred shares. Each
          American Depositary Share (ADS) for common shares represent one share
          of the Company's common shares or one share of the Company's preferred
          shares and, in each case, is presented together with earnings per
          share.

     (p)  Research and development costs

          Research and development costs are charged to expense when incurred.

     (q)  Accounting for derivatives and hedging activities

          The Company adopted SFAS No. 133 - Accounting for Derivative
          Instruments and Hedging Activities ("SFAS 133"), as amended by SFAS
          No. 137 - Accounting for Derivative Instruments and Hedging Activities
          - Deferral of the Effective Date of SFAS No. 133 ("SFAS 137") and SFAS
          No. 138 - Accounting for Certain Derivative Instruments and Certain
          Hedging Activities ("SFAS 138"), on January 1, 2001. SFAS 133 requires
          that all derivative instruments be recorded in the balance sheet of
          the Company as either an asset or a liability measured at fair value.
          SFAS 133 requires that changes in the derivative's fair value be
          recognized in earnings/losses unless specific hedge accounting
          criteria is met. For derivatives accounted for as hedges, fair value
          adjustments are recorded to earnings/losses or other comprehensive
          income, a component of shareholders' equity, depending upon the type
          of hedge and the degree of hedge effectiveness. The Company has
          determined that none of its derivative financial instruments that had
          been previously treated as hedges qualified for hedge accounting under
          the new standard. The net-of-tax cumulative-effect recorded on January
          1, 2001 to recognize the Company's derivative financial instruments
          were not significant.

          The Company may use derivative financial instruments to mitigate the
          risk of unfavorable price movements on crude oil purchases. These
          instruments are marked-to-market on a current basis and associated
          gains and losses are recognized currently in the income statement.

          The Company may also use derivative financial instruments to mitigate
          the risk of unfavorable exchange-rate movements affecting its foreign
          currency-denominated indebtedness. Gains and losses from changes in
          the fair value of these contracts are recognized in income currently,
          in the same line item as foreign exchange gains and losses arising on
          the Company's outstanding debt balance.

          PEPSA also uses derivative instruments such as swaps, options,
          futures, and other instruments, principally to mitigate the impact of
          changes in crude oil prices, exchange rates and interest rates.
          PEPSA's crude oil derivative instruments and interest rate swap
          instruments are designed to mitigate specific exposures and thus
          qualify as cash flow hedges under SFAS 133. As cash flow hedges, the
          gains and losses associated with the derivative instrument are
          deferred and recorded in other comprehensive income until the
          underlying hedge transaction impacts earnings, with the exception of
          any ineffective portions. Derivative instruments not qualifying for
          hedge accounting are marked-to-market through earning on a current
          basis.

     (r)  Recently issued accounting pronouncements

          EITF Issue 86-12, "Accounting by Insureds for Claims-Made Insurance
          Policies", EITF Issue 03-3, "Accounting for Claims-Made Insurance
          Policies by the Insured Entity", and EITF Abstracts Topic D-79,
          "Accounting for Retroactive Insurance Contracts Purchased by Entities
          Other than Insurance Enterprises", address various aspects of the
          accounting for retroactive insurance contracts and claims-made
          insurance policies by the insured entity. EITF Issue 03-8 finished
          discussion in November of 2003 and has the purpose to codify the
          guidance set forth in the aforementioned pronouncements. The Company
          contracts claims made insurance policies on a prospective basis only
          and records provisions, as applicable, for all probable losses that
          may result under SFAS No. 5 - Accounting for Contingencies ("SFAS 5").

     (s)  Reclassifications

          Certain prior years' amounts have been reclassified to conform with
          the current year's presentation. These reclassifications had no impact
          on the Company's net income or shareholders' equity.

3.   Accounting change

     (a)  SFAS No. 143 - Accounting for asset retirement obligations

          As of January 1, 2003, PETROBRAS adopted SFAS No. 143 - Accounting for
          Asset Retirement Obligations ("SFAS 143"). The primary impact of SFAS
          143 is to change the method of accruing for upstream site restoration
          costs. These costs were previously accrued ratably over the productive
          lives of the assets in accordance with SFAS No. 19 - Financial
          Accounting and Reporting by Oil and Gas Producing Companies ("SFAS
          19"). At the end of 2002, the cumulative amount accrued under SFAS 19
          was US$ 1,166.

          This provision for abandonment was recognized as a component of
          accumulated depreciation, depletion and amortization as of December
          31, 2002, with no separate provision for abandonment liability being
          disclosed on the face of the financial statements. Under SFAS 143, 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.

          The cumulative adjustment for the change in accounting principle
          reported in the first quarter of 2003 was an after-tax income of US$
          697 (net of US$ 359 deferred income tax effects). The effect of this
          accounting change on the balance sheet, was a US$ 1,056 reduction to
          the abandonment provision, and a US$ 359 increase in deferred income
          tax liabilities, see Note 4. Additionally, the change in accounting
          principle resulted in a US$ 16 increase to property, plant and
          equipment at original asset acquisition date, with accumulated
          depreciation through January 1, 2003 of US$ 9 on proved developed
          properties. Further, on January 1, 2003, PETROBRAS established an
          abandonment liability with respect to proved undeveloped reserves in
          the amount of US$ 44.

          This adjustment is due to the difference in the method of accruing
          site restoration costs under SFAS 143 compared with the method
          required by SFAS 19. Under SFAS 19, site restoration costs are accrued
          on a unit-of-production basis of accounting as the oil and gas are
          produced. The SFAS 19 method matches the accruals with the revenues
          generated from production and results in most of the costs being
          accrued in early field life, when production is at the highest level.
          Because SFAS 143 requires accretion of the liability as a result of
          the passage of time using an effective interest method of allocation,
          a significant portion of costs will be accrued towards the end of
          field life, when production is at the lowest level. The cumulative
          income adjustment described above results from reversing the higher
          liability accumulated under SFAS 19 in order to adjust it to the lower
          present value amount resulting from transition to SFAS 143. This
          amount being reversed in transition, which was previously charged to
          operating earnings under SFAS 19, will again be charged to earnings
          under SFAS 143 in future years.

          Measurement of assets 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 abandonment provision are
          presented as follows:

                                                    Assets      Liabilities

          No. 46 (FIN 46) - Consolidation of Variable Interest Entities in
          January of 2003. FIN 46 provides guidance on when certain entities
          should be consolidated or the interests in those entities disclosed by
          enterprises that do not control them through a majority voting
          interest. Under FIN 46, entities are required to be consolidated by an
          enterprise that has a controlling financial interest in such entities
          when equity investors of that enterprise do not have significant
          capital risk, the obligation to absorb the majority of expected
          losses, or the right to receive the majority of expected returns from
          such entities. Entities identified with these characteristics are
          called variable interest entities and the interest that enterprises
          have in these entities are called variable interests. These interests
          may derive from certain guarantees, leases, loans or other
          arrangements that result in risks and rewards to the enterprise with
          the controlling financing interest in such entities, irrespective of
          such enterprises' voting interest in such entities.

          The interpretation requires that if a business enterprise has a
          controlling financial interest in a variable entity, the assets,
          liabilities and results of the activities of the variable interest
          entity must be included in the consolidated financial statements with
          those of the business enterprise. This interpretation applies
          immediately to variable interest entities created after January 31,
          2003. For variable interest entities created before February 1, 2003,
          FIN 46 must be adopted in the first reporting period ending after
          December 15, 2003.

          The Company adopted FIN 46 in its December 31, 2003 annual financial
          statements. Such adoption resulted in the consolidation of a number of
          special purpose entities related to project financing arrangements in
          which the Company has an interest, and which were deemed to be
          variable interest entities for which the Company was the primary
          beneficiary. These entities are detailed above in Note 2 (b). Prior to
          adoption of FIN 46, a significant portion of the Company's share of
          commitments and debt obligations, as well as fixed asset
          contributions, were already included in the consolidated financial
          statements as the project financing transactions qualified as capital
          leases.

          Thus, adoption of FIN 46 related to the special purpose companies
          formed in connection with project finance arrangements did not have a
          significant impact on the Company's financial condition. While
          PETROBRAS does not have specific assets set aside and established as
          collateral for these special purpose entities, the Company does have
          certain contractual obligations relating to the debt of the special
          purpose entities.

          Three thermoelectric plants were also consolidated at December 31,
          2003 as a result of the adoption of FIN 46. However, as these
          thermoelectric plants had previously been accounted for as capital
          leases, their consolidation did not have a material impact on the
          Company's financial condition.

          Furthermore, PETROBRAS has determined that it is the primary
          beneficiary of three additional plants for which it has certain
          contractual obligations to bear energy market risk. The effect of the
          consolidation of these three thermoelectrics was an increase in fixed
          assets of US$ 1,142 and an increase in liabilities of US$ 1,142.
          Results of operations for these companies will only be consolidated in
          2004.

     (c)  EITF 01-08 - Determining whether an arrangement contains a lease

          EITF 01-08 "Determining Whether an Arrangement Contains a Lease,"
          expands former guidance respective to determination of whether an
          arrangement contains a lease that is within the scope of SFAS No. 13 -
          Accounting for Leases, ("SFAS 13") and offers specific guidance
          related to transportation and other energy contracts that may qualify
          as leases. Adoption of this EITF in 2003 did not have a significant
          impact on the Company's accounting for its energy and transportation
          contracts.

     (d)  EITF 02-6 - Classification in the statement of cash flows of payments
          made to settle an asset retirement obligation

          PETROBRAS has adopted the presentation outlined in EITF 02-6 -
          Classification in the Statement of Cash Flows of Payments made to
          Settle an Asset Retirement Obligation within the Scope of SFAS 143,
          with immaterial changes to prior classification of such costs as
          investment activities.

4.   Income taxes

     Income taxes in Brazil comprise federal income tax and social contribution,
     which is an additional federal income tax. The statutorily enacted tax
     rates applicable in the years are presented as follows:

                                       Year ended December 31, - %

     During 2001, the Company recognized a benefit in the amount of US$ 111,
     relating to the reversal of a tax provision established in previous years
     in connection with the privatization of certain affiliates of PETROQUISA
     included in the National Privatization Program (PND) due to expiration of
     the statute of limitations.

     Also during 2001, certain changes were introduced in the Brazilian tax
     legislation, including a requirement that earnings from foreign
     subsidiaries be included in the determination of current taxes payable in
     Brazil. As a result, the Company recorded a provision of US$ 100 relating
     to income taxes on its foreign subsidiaries undistributed taxable income
     generated since 1996.

     Substantially all of the Company's taxable income is generated in Brazil
     and is therefore subject to the Brazilian statutory tax rate. The following
     table reconciles the tax calculated based upon statutory tax rates to the
     income tax expense recorded in this consolidated financial statements.

     TBG, a subsidiary of GASPETRO, has accumulated tax loss and negative income
     tax and social contribution carryforwards amounting to US$ 469 (US$ 768 in
     2002) as of December 31, 2003, which could be offset against future taxable
     income to a limit of 30% of annual income, based on Law No. 9,249/95, which
     in the opinion of the TBG management, will occur within the useful life of
     the Bolivia-Brazil Gas Pipeline project.

     However, considering the long estimated term for utilization, these tax
     credits, totaling US$ 159 (US$ 239 - 2002), were provided for in a
     valuation allowance in the consolidated financial statements for December
     31, 2003 and 2002. The accounting recognition of these credits is reviewed
     annually.

     The major components of the deferred income tax accounts in the
     consolidated balance sheet are as follows:

      As a result of the NTN-P swap transaction in 2001, described in Note 6,
      the income tax on interest on government securities held-to-maturity,
      which payment had been deferred, became payable and the corresponding
      provision for income tax and social contribution was transferred to
      current liabilities on December 28, 2001.





4.    Income taxes--Continued Year



      Although realization of net deferred tax assets is not assured, management
      believes that, except where a valuation allowance has been provided, such
      realization is more likely than not to occur. The amount of the deferred
      tax asset considered realizable could, however, be reduced if estimates of
      future taxable income are reduced. Tax loss carryforwards do not expire
      and are available for offset against future taxable income, limited to 30%
      of taxable income in any individual year. The following presents the
      changes in the valuation allowance for the end years ended December 31,
      2003, 2002 and 2001:

6.    Government securities

      On December 28, 2001, PETROBRAS entered into a contract with the Federal
      Government to exchange the restricted National Treasury Bonds "Series P"
      (NTN-P) for unrestricted National Treasury Notes - Series B (NTN-B) with a
      face value of US$ 3,239. The NTN-P had previously been accounted for as
      held-to-maturity securities. The NTN-B were created on July 4, 2001 by
      means of Federal Decree No. 3,859. The exchange was accounted for at fair
      value and a loss of US$ 1,099 was recorded in the results of operations
      for 2001. The NTN-B were classified as available-for-sale, and on December
      28, 2001, the Company transferred NTN-B notes with a fair value of US$
      1,475 to PETROS, the Company's current pension plan for employees (see
      Note 17) to increase pension assets.

      On December 30, 2002, the Company effectively transferred a portion of the
      NTN-B with a fair value of US$ 388 to PETROS to further increase plan
      assets.

      The Company has retained title to NTN-B amounting to US$ 283 as of
      December 31, 2003 (US$ 176 as of December 31, 2002). These bonds have been
      advanced to PETROS and the Company intends to utilize them to provide
      incentives for participants to migrate from the PETROS Plan to the
      PETROBRAS VIDA, the Company's new pension plan for employees (see Note
      17). Accordingly, as the Company still has the risks and rewards relating
      to the bonds, they are accounted for as securities available-for-sale and
      their corresponding earnings will be recorded on an amortized cost basis,
      with changes in fair value presented in the statement of shareholders'
      equity as a component of other comprehensive income.

      The NTN - B are denominated in reais, earn interest at 6% annually plus
      the variation of the IPCA (Consumer Price Index - Adjusted) and mature in
      2031.

7.    Accounts receivable, net--Continued

      At December 31, 2003 and 2002, long-term receivables include US$ 581 and
      US$ 569 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.

      Based on opinions from the legal advisers of BRASOIL, these payments can
      be reimbursed, since they represent a right of BRASOIL with respect to the
      contractors, for which reason judicial action was filed with international
      courts to seek financial reimbursement. However, as a result of the
      uncertainties with regards to the probability of receiving all the amounts
      disbursed, the Company recorded a provision for uncollectible accounts for
      all credits that are not backed by collateral. The balances of this
      provision amounted US$ 509 and US$ 497 as of December 31, 2003 and 2002.

      The Company prevailed in the lawsuit filed with an American court by the
      insurance companies Fidelity & Guaranty Company and American Home
      Assurance Company, which had attempted to obtain, since 1997, a legal
      ruling in the United States to exempt the insurance companies from the
      obligation to pay the sum insured for the construction of platforms P-19
      and P-31. As a result of a court decision by the first level of the
      Federal District Court of the Southern District of New York, the Company
      was entitled to receive losses and damages in the amount of US$ 237, plus
      interest and reimbursement of legal expenses through the settlement date.
      This decision is pending appeal to the Appeals Court of the State of New
      York, and therefore the Company has not recognized this amount in the
      financial statements.

9.    Property, plant and equipment--Continued

(a)   Composition of balance--Continued

      The property, plant and equipment account at December 31, 2003 and 2002,
      respectively, includes US$ 678 and US$ 292 of assets under construction
      that are intended to be sold or transferred into structured financing
      deals. These assets include natural gas pipelines and other oil and gas
      projects at 2003, and thermoelectric plants, natural gas pipelines and
      other oil and gas projects at 2002. Additionally, the property, plant and
      equipment account at December 31, 2003 and 2002, respectively, includes
      US$ 978 and US$ 653 of assets under agreements with investors.

      The property, plant and equipment balance at December 31, 2003, includes
      US$ 5,775 of assets consolidated as a result of the adoption of FIN 46. Of
      this amount, US$ 3,718 was previously included in the property, plant and
      equipment balance at December 31, 2002 for special purpose project
      financing entities and certain thermoelectric plants accounted for as
      capital leases. The increase to property, plant and equipment resulting
      from the adoption of FIN 46 is related to the consolidation of three
      thermoelectric plants which were previously only recognized as guarantees;
      see Note 16.

(b)   Impairment

      For the years ended December 31, 2003, 2002 and 2001, the Company recorded
      impairment charges of US$ 70, US$ 75 and US$ 145, respectively. During
      2003, US$ 65 of the impairment charge was related to producing properties
      in Brazil, principle amounts were related to the Company's Fazenda Belem
      on-shore field (US$ 15) in Rio Grande do Norte, and the Lamarao on-shore
      field (US$ 4) in Bahia. During 2002, US$ 75 of the impairment charge was
      related to producing properties in Brazil, primarily recorded in the
      Company's Voador field (US$ 42) in the Campos basin, Caravelas field (US$
      15) in the Santos basin and Massape field (US$ 4) in the Reconcavo basin.

(b)   Impairment--Continued

      During 2001, US$ 129 of the impairment charge was related to producing
      properties in Brazil and was primarily recorded in the Company's Voador
      field (US$ 88) in the Campos basin and Caravelas field (US$ 30) in the
      Santos basin. The remaining US$ 16 were recorded in the international
      segment primarily in the Company's Upia field (US$13) located in Colombia.
      These charges were recorded based upon the Company's annual assessment of
      the fields using pricing and other assumptions consistent with those used
      in the Company's overall strategic plan.

(c)   Return of exploration areas to the ANP

      During 2003, PETROBRAS returned to the ANP the rights to over twenty two
      exploratory concessions where it had not made any oil or gas discoveries.

      Thus, total concessions returned are as follows: 113 (one hundred and
      thirteen) of the 115 (one hundred and fifteen) concessions granted to the
      Company on August 6, 1998; 2 (two) of the 5 (five) exploratory concessions
      areas acquired under the "BID 1" in June of 1999; and 50% of the original
      areas related to 8 (eight) exploratory concession areas acquired under the
      "BID 2", in June of 2000.

(d)   5th ANP auction of exploratory blocks

      The Company acquired 88 (eighty-eight) new exploratory concessions of the
      908 (nine hundred and eight) blocks offered by ANP in the 5th bid for
      exploratory blocks held in August of 2003. The Company has exclusive
      rights over 85 (eighty-five) of these concessions and the other 3 (three)
      were acquired under a consortium. The Company is not the operator of the
      consortium. The costs incurred by the Company in subscription bonus
      totaled US$ 7.



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
      products transportation businesses.


                                                                                    Investments

                                                                        =================== ==================



      (a)   As described further in this Note, certain thermoelectrics with
            ownership of 10% to 50% are also accounted for as equity investments
            due to particularities of control.

      During 2003, the Company acquired PEPSA and PELSA (see Note 19), that hold
      interests in other companies that are recorded according to equity method
      or at cost. The balance of those investments as of December 31, 2003
      amounted to US$ 401 of which US$ 348 was recorded using the equity method.
      Those companies operate mainly in exploration and production, refining,
      transport and commercialization, electricity generation, transmission and
      distribution, and petrochemicals.

      At December 31, 2003 and 2002, the Company had investments in companies
      with publicly traded shares: BRASKEM S.A., Petroquimica Uniao S.A. - PQU
      and Companhia Petroquimica do Sul S.A. - COPESUL. The Company's
      investments in these companies with publicly traded shares amounts to less
      than 20% of the investee's total voting shares, are classified as
      available for sale and have been recorded at market value. The Company has
      recorded unrealized gains (losses) for the difference between the fair
      value and the cost of the investment on these investments of US$ 207 and
      US$ (16) as of December 31, 2003 and 2002, respectively. These holding
      (losses) gains are reflected as a component of shareholder's equity, net
      of tax, with changes in the unrealized balance recorded as a component of
      comprehensive income.



10.   Investments in non-consolidated companies and other investments--Continued

      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 the investments as of December 31, 2003 and 2002
      includes US$ 46 and US$ 38 respectively, and are included as equity method
      investments due to the Company's ability to influence such operations.

      The Company's investment in equity of non-consolidated companies generated
      equity gains (losses) in results of non-consolidated companies of US$ 141
      for the year ended December 31, 2003 (2002 - US$ (178); 2001 - US$ (8)).

      (a)   Deregulation of the Brazilian fuel market

      In accordance with the Petroleum Law and subsequent legislation, the fuel
      market in Brazil was deregulated in its entirety as of January 1, 2002.
      Therefore, as of that date, the Petroleum and Alcohol account would no
      longer be used to reimburse expenses in connection with the Federal
      Government's regulation of the prices of oil products and fuel alcohol.
      Accordingly, the Petroleum and Alcohol account will only include changes
      in amounts with triggering events having occurred before December 31,
      2001, in accordance with Law No. 10,453, of May 13, 2002, and ANP
      regulations. See additional discussion at Note 2 respective to market
      regulation in Brazil and the effect of such on the historical financial
      statements.

      (c)   Certification by the Federal Government


      The Federal Government certified the balance of the Petroleum and Alcohol
      Account as of June 30, 1998.

      The changes in the Petroleum and Alcohol Account in the period July 1,
      1998 to December 20, 2002 are subject to audits by the ANP. The results of
      the audit will be the basis for the settlement of the account with the
      Federal Government.

      The settlement of the account with the Federal Government should have been
      completed by December 31, 2002, according to the provisions of Law No.
      10,453 of May 13, 2002, amended by Decree No. 4,491 of November 29, 2002.
      On June 26, 2003 Provisional Measure 123, article 11, which was converted
      to Law No. 10,742 dated October 6, 2003, extended the term of settlement
      of accounts involving reciprocal debits and credits between PETROBRAS and
      the Federal Government to June 30, 2004, and in so doing, automatically
      extending the term for certification of the outstanding balance in the
      Petroleum and Alcohol Account.





11.   Receivable from Federal Government--Continued

      (d)   National Treasury Bonds Series H (NTN-H)

      On June 30, 1998, the Company and the Federal Government reached an
      agreement whereby the Federal Government issued National Treasury Bonds -
      H (NTN-H) into a federal depositary on behalf of the Company to support
      the balance of the Petroleum and Alcohol account. On June 27, 2003, the
      National Treasury Secretary issued Administrative Instruction 348,
      authorizing the cancellation of 138,791 NTN-H, which expired on June 30,
      2003 and were held in guarantee of payment of an outstanding balance in
      the Petroleum and Alcohol Account and the issue of new 138,791 NTN-H, with
      the same terms as the cancelled bonds but expiring on June 30, 2004. The
      value of the outstanding bonds at December 31, 2003 was US$ 59, at which
      time the balance of the Petroleum and Alcohol Account was US$ 239. The
      legal, valid, and binding nature of the account is not affected by any
      difference between the balance of the account and the value of the
      outstanding bonds.


      The Brazilian Government, upon the Company's consent, can effect the
      cancellation of all or a portion of the bonds' outstanding balance. The
      NTN-H will mature on June 30, 2004 and currently PETROBRAS has no other
      rights on those bonds; withdrawal or transfers are not allowed.


12.   Financings


      (a)   Short-term debt


      The Company's short-term borrowings are principally sourced from
      commercial banks and include import and export financing denominated in
      United States dollars, as follows:


                                                                                    As of December 31,

              the PETROBRAS group companies in the total amount of US$ 920.
              These securities are considered to be extinguished, and thus the
              related amounts, together with applicable interest have been

            o     Composition of long-term debt by annual interest rate

            On October 24, 2003, Petrobras Energia S.A. issued US$ 100 notes -
            Series R, with a 9.375% annual coupon payable semiannually, and a
            9.5% annual yield to maturity, and due date of 2013.

            o     Structured finance of exports


            Respective to the Senior and Junior Notes issued pursuant to the
            structured finance program, PETROBRAS and Petrobras Finance Ltd. -
            PFL have certain contracts (Master Export Contract and Prepayment
            Agreement) between themselves and special purpose entity not related
            to PETROBRAS, PF Export Receivables Master Trust ("PF Export"),
            relating to the prepayment of export receivables to be generated by
            PFL by means of sales on the international market of fuel oil and
            other products acquired from PETROBRAS.

            As stipulated in the contracts, PFL assigned the rights to future
            receivables in the amount of US$ 1,800 (1st and 2nd tranches) to PF
            Export, which, in turn, issued and delivered to PFL the following
            securities, also in the amount of US$ 1,800:

            -     US$ 1,500 in Senior Trust Certificates, which were negotiated
                  by PFL on the international market at face value. The amount
                  was transferred to PETROBRAS as prepayment for exports to be
                  made to PFL, according to the prepayment agreement.

            -     US$ 300 in Junior Trust Certificates, which are held in the
                  portfolio of PFL. If PF Export incurs any losses on the
                  receipt of the value of the exports transferred by PFL, these
                  losses will be compensated by the Junior Trust Certificates.

            The assignment of rights to future export receivables represents a
            liability of PFL, which will be settled by the transfer of the
            receivables to PF Export as and when they are generated. This
            liability will bear interest on the same basis as the Senior and
            Junior Trust Certificates, as described above.

            o     Structured finance of exports--Continued

            In May of 2003, the PF Export Trust issued to the Company additional
            US$ 750 in Senior Trust Certificates and US$ 150 in Junior Trust
            Certificates. The Senior Trust Certificates consist of Series 2003-A
            of US$ 550 bearing annual interest of 6.436% and due in June of 2015
            and Series 2003-B of US$ 200 bearing annual interest due of 5.548%
            due in June of 2013. The Junior Trust Certificates were issued with
            complementary terms as the new Senior Trust Certificates as they
            form a 20% guarantee to the senior trust certificates and expire
            ratably. These two new issuances complement the initial structured
            finance export prepayment program commenced in December of 2001.

      (d)   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
      (vessels).

      (d)   Guarantees and covenants--Continued


      At December 31, 2003 and 2002, 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.

      which had an outstanding balance of US$ 463 and US$ 487 at December 31,
      2003 and 2002, respectively. During 2000, the Federal Government, the
      Company, TBG, PETROQUISA and Banco do Brasil S.A. entered into an
      agreement whereby the revenues of TBG will serve as a counter-guarantee to
      this debt until the debt has been extinguished.

      PETROBRAS entered into standby purchase agreements in support of the
      obligations of its wholly-owned subsidiary under the note issuances in
      2001, 2002 and 2003 and their respective indentures. PETROBRAS has the
      obligation to purchase from the noteholders any unpaid amounts of
      principal, interest or other amounts due under the notes and the indenture
      applies, subject to certain limitations, irrespective of whether any such
      amounts are due at maturity of the notes or otherwise.

14.   Project financings


      Since 1997, the Company has utilized project financing to provide capital
      for the continued development of the Company's exploration and production
      and related projects.

      Through 2002 and the majority of 2003, the Company's arrangements with
      respect to these projects were considered capital leasing transactions for
      accounting purposes. Effective December 31, 2003, the Company adopted FIN
      46 and the project financing special purpose entities were consolidated on
      a line by line basis. Thus at year-end 2002, the project finance
      obligation represents the present value of the future value of capital
      lease commitments, while at December 31, 2003, the project finance
      obligation represents the debt of the consolidated SPE with the third
      party lender.

      As the assets related to the project finance special purpose entities and
      the related capital lease obligations were already recorded in the
      accounts of the Company at December 31, 2003, the adoption of FIN 46
      related to the project finance entities did not have a material impact on
      the financial statements.

      The Company's responsibility under these contracts is to complete the
      development of the oil and gas fields, operate the fields, pay for all
      operating expenses related to the projects and remit a portion of the net
      proceeds generated from the fields to fund the special purpose companies'
      debt and return on equity payments. At the conclusion of the term of each
      financing project, the Company will have the option to purchase the leased
      or transferred assets from the consolidated special purpose company.

      The following summarizes the liabilities related to the projects that were
      in progress at December 31, 2003 and 2002:



                                                                               As of December 31,

      PETROBRAS has received certain advances in the amount of US$ 593 which are
      recorded as project finance obligations and are related to assets under

      Barracuda/Caratinga


      On June 23, 2000 the Company completed its project finance negotiations
      with the Barracuda Caratinga Leasing Company B. V. (BCLC), a special
      purpose entity formed by a group of international financial institutions
      for the sole purpose of raising US$ 2,500 for the development of the
      Barracuda and Caratinga oil and gas fields located in the Campos Basin.
      Permanent funding for this project has been raised from two governmental
      institutions (Japan's Bank of International Cooperation - JBIC and the
      BNDES) and from a syndicate of commercial banks. In conjunction with this
      project, the Company will contribute US$ 1,035 of drilling services
      through a drilling services contract signed with the Halliburton Company.


      From early 2003, KBR has been announcing to the market its intention to
      file a Chapter 11 case with the U.S. courts, specifically limited to its
      asbestos business; such filing was completed in the second half of
      December 2003. As informed by KBR in its official announcements to the
      market, the bankruptcy protection proceedings would not directly impact
      the remaining businesses, including its obligations under the
      Barracuda/Caratinga Project EPC contract.

      In the capacity as "Owner's Representative" under the project, at June 17,
      2003, PETROBRAS, on behalf of BCLC, finalized negotiations with KBR
      involving claims made by KBR for time extensions and project cost
      increases. After formal approval from the project sponsors, as
      contractually defined, such negotiations resulted in an amendment to the
      original agreement, as approved on November 7, 2003. The objectives of
      such amendment are to mitigate the risks involved, especially the risk
      related to the bankruptcy protection filed by KBR, and ensures asset
      construction completion in the shortest period. The original package of
      guarantees has been maintained and new guarantees are expected to be
      provided by KBR.

      On January 12, 2004, KBR officially announced that the judge responsible
      for its Chapter 11 filing accepted the position advanced by KBR whereby
      bankruptcy proceedings should be limited to its asbestos business, without
      prejudice to the development of other businesses of the company, including
      the Barracuda/Caratinga project.

      Cabiunas

      On March 1, 2000, the Company completed its project finance negotiations
      with the Cayman Cabiunas Investment Co. Ltd., a special purpose entity
      formed by the Mitsui and Sumitomo banks for the sole purpose of raising
      US$ 850 for the expansion of the Cabiunas Complex located in Macae, in the
      state of Rio de Janeiro. Permanent financing was provided by JBIC, a
      syndicate of commercial banks led by the Bank of Tokyo-Mitsubishi and the
      special purpose company's equity investors.

      Espadarte/Voador/Marimba (EVM)

      On June 23, 2000, the Company completed its project finance negotiations
      with the EVM Leasing Corporation (EVMLC), a special purpose entity formed
      by a group of international financial institutions for the sole purpose of
      raising US$ 1,600 for the development of the Espadarte, Voador and Marimba
      oil and gas fields located in the Campos Basin. Permanent funding for the
      EVM project was provided by a syndicate of international financial
      institutions, Japanese trading companies, JBIC and BNDES. Bridge financing
      in the amount of US$ 300 for this project was prepaid in December of 1999.
      Upon closing of the agreement, the Company sold previously identified oil
      and gas assets to EVM, who leased them back to the Company.

      Marlim

      On December 14, 1998, the Company entered into a consortium agreement with
      Companhia Petrolifera Marlim (CPM), a single purpose entity formed in
      November of 1998 by a group of international financial institutions for
      the sole purpose of raising US$ 1,500 for the expansion and continued
      development of the Marlim oil field. In December of 1999, CPM raised US$
      200 through a medium term note program, and an additional US$ 300 in 2000.
      Upon closing of the consortium agreement, the Company sold certain assets
      to CPM, who leased them back to the Company. Effective June 30, 1999
      PETROBRAS conveyed its remaining assets in the Marlim field to CPM, that
      also leased them back to the Company. Additionally, in June of 1999, the
      shareholders of CPM and the Company entered into a Stock Option Agreement
      granting to the Company a call option at the end of the lease and to the
      shareholders of CPM a put option to the Company in the case of default.

      Nova Marlim

      On December 6, 2001, the Company entered into a consortium agreement with
      Nova Marlim Petroleo S.A., a special purpose entity formed by a group of
      international financial institutions for the sole purpose of raising US$
      933 for the complementary development and production optimization of the
      Marlim oil field.

      Albacora

      During 2000, the Company finalized negotiations for two separate financing
      projects related to the Albacora oil field located in the Campos basin. On
      November 28, 2000, the Company completed its negotiations related to a
      project financing arrangement with the Albacora Japan Petroleum Limited
      Company (AJP), a special purpose corporation formed in December of 1998
      for the sole purpose of providing financing for the continued development
      of the Albacora oil field. AJP's operations commenced in December of 2000
      with the purchase of certain oil and gas assets from the Company. AJP
      provided these assets exclusively to the Company in return for minimum
      proceeds of US$ 208 to be generated from the field's production.

      Permanent financing was provided by JBIC, the Japan National Oil Company
      (JNOC) and certain Japanese trading companies. In addition, in December of
      2000, PETROS, the Company's pension plan, agreed to provide funding for
      the development of this oil field. During 2000, PETROS advanced US$ 240
      for the continued development of the field, and this amount has been
      classified together with the AJP financing transaction. AJP does not have
      any further funding needs.

      Pargo, Carapeba, Garoupa, Cherne and Congro (PCGC)

      The PCGC is an offshore development project in the Pargo, Carapeba,
      Garoupa, Cherne and Congro fields. The project is a secondary extraction
      project using water-injection technology to reestablish the appropriate
      level of pressure in the reservoirs to maximize the recovery of oil and
      gas in these fields. In addition, the PCGC project includes equipment for
      new oil reserves in the Congro field. Management estimates total costs of
      the PCGC project to be US$ 134.

      Malhas Project

      In order to implement a pipeline network for the transportation of gas in
      the Southeast and Northeast regions (MALHAS Project), the Company, through
      its subsidiaries GASPETRO and TRANSPETRO, entered into a consortium with
      the SPCs Nova Transportadora do Sudeste (NTS) and Nova Transportadora do
      Nordeste (NTN). NTS and NTN will participate in the consortium by
      acquiring assets related to the transportation of natural gas (gas
      pipelines, citygates and accessories), in the amount of up to US$ 1,000,
      US$ 92 of which had already been allocated, to be integrated in the
      existing gas pipeline network of PETROBRAS. Funds to be allocated to the
      project by NTS and NTN will derive from own capital (10%) and from
      financing operations obtained in the financial market.

      In addition to NTS and NTN, the MALHAS consortium also includes the
      wholly-owned subsidiary of the Company, Transportadora Nordeste Sudeste
      (TNS), to which existing gas transportation assets belong, and by
      TRANSPETRO, which is responsible for the activities involved in the
      operation and maintenance of the consortium assets. Upon commencement of
      operations, the consortium will transport the natural gas of PETROBRAS,
      which will pay the consortium a fee for the services provided. Revenues
      arising from this project will be shared among the consortium members in
      accordance with pre-defined contractual terms, and NTS and NTN will
      receive funds in an amount necessary to fulfill their financial
      obligations. The Company is committed to making prepayments for
      transportation capacity to cover any cash shortfalls of the consortium, so
      that it may transfer to NTS and NTN the funds necessary for the
      fulfillment of their financial obligations under the agreement. The MALHAS
      consortium was not operational as of December 31, 2003 and, accordingly,
      the Company did not make any payments for gas transportation services.



14.   Project financings--Continued

      Langstrand Project

      Through a financing structure that involves the SPC Langstrand Holdings
      S.A., the Company will sell to this company assets related to the
      production of oil, located in the Campos Basin, and subsequently will
      lease such assets back through a leasing agreement. The funds necessary
      for Langstrand to acquire the assets from PETROBRAS will be provided by
      shareholders capital (equivalent to US$ 70) and from the financing
      operations obtained in the international financial markets through the
      issuance of Medium Term Notes backed by Langstrand receivables (lease
      payments to be made by PETROBRAS).

      Lease payments are due on a semi-annual basis from June of 2004.
      Langstrand revenues will arise solely from the semi-annual lease payments
      to be made by PETROBRAS for the use of the assets and PETROBRAS also
      ensures the payment of additional lease payments in the event that
      Langstrand revenues are not sufficient to cover its financial obligations
      related to the project. In an event of default, PETROBRAS is committed to
      acquire the SPC for the remaining balance of its obligations.

15.   Capital leases

      In 2002, the Company leased certain offshore platforms, vessels and
      thermoelectric plants, which are accounted for as capital leases. At
      December 31, 2003, the Company continued to lease these offshore platforms
      and vessels, and continued to account for such as capital leases. However,
      pursuant to the adoption of FIN 46, three thermoelectric plants which were
      previously accounted for as capital leases have been consolidated by the
      Company. At December 31, 2003, assets under capital lease had a net book
      value of US$ 1,749 (US$ 2,499 at December 31, 2002, including
      thermoelectrics).



15.   Capital leases--Continued


      The following is a schedule by year of the future minimum lease payments
      at December 31, 2003:

      2004                                                               388

                                                                   ----------

Long-term portion                                                      1,242
                                                                   ==========


16.   Thermoelectric plant obligations

      As a result of adopting FIN 46 at December 31, 2003, the Company now
      consolidates six thermoelectric plants. Previously, three of these
      thermoelectric were accounted for as capital leases, while the other three
      were considered contractual obligations concerning third-party interests,
      with amounts equal to contingency payments required to be funded under the
      contracts recognized to the extent the related payments are deemed
      probable and can be estimated in accordance with the provisions of SFAS 5.



16.   Thermoelectric plant obligations--Continued

      The consolidation of the three thermoelectrics formerly treated as capital
      leases resulted in US$ 375 being reclassified from capital lease
      obligations to long-term debt obligations (see Note 15). The impact of
      changing the obligations related to these three plants from the minimum
      value of future lease payments to the debt outstanding with third party
      lenders was immaterial. At December 31, 2003, the consolidation of the
      three thermoelectrics previously accounted for as contractual obligations
      concerning third party interests resulted in an increase to assets and
      long-term obligations of US$ 1,142.

      At December 31, 2002, the Company had commitments with thermoelectric
      plants related to (a) the supply of natural gas for the production of
      energy and the purchase of all or a portion of the energy generated by
      these plants and (b) commitments to reimburse certain allocations as
      defined per the Consortium Agreements. At December 31, 2002 the provision
      for future losses on energy business recorded by the Company amounted to
      US$ 205. On May 7, 2003, the Executive Board authorized an increase in the
      above-mentioned accounting provision for US$ 205, in the first quarter of
      2003 especially considering that the originally expected sales of energy
      available through Power Purchase Agreements (PPA's) in 2003 and the
      technical supply level of thermoelectric power plants were not confirmed,
      principally as a result of a retraction in demand following the energy
      rationing program and of the lack of a well defined regulatory framework
      for the energy sector. The provisions accrued at year-end 2002 and in the
      first quarter of 2003, respective to 2003 exposure was substantially
      utilized during the course of the year.

      At December 31, 2003 as a result of adoption of FIN 46, the Company has
      consolidated the thermoelectric plants and recognized a corresponding
      liability. Thus, it is no longer necessary to recognize any additional
      liability for future payments expected to be made under the agreements
      with the sponsors of the thermoelectric plants. The Company will recognize
      any losses from operations of the plant if and when incurred.

            The Fundacao Petrobras de Seguridade Social (PETROS) and the current
            benefits plan (the PETROS Plan)

            The Fundacao Petrobras de Seguridade Social (PETROS) was established
            by PETROBRAS as a private, legally separate nonprofit pension entity
            with administrative and financial autonomy. As such, PETROS has the
            following principle objectives:

            (i)   institute, manage and execute benefit plans for the companies
                  or entities with which it has signed agreements;

            (ii)  provide administration and execution services for benefit
                  plans focused on postretirement payments; and

           (iii)  promote the well-being of its members, especially with respect
                  to postretirement payments.

            The Fundacao Petrobras de Seguridade Social (PETROS) and the current
            benefits plan (the PETROS Plan)--Continued

            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
            subsidiaries and affiliated companies. In order to fund its
            objectives, PETROS receives monthly contributions from the
            sponsoring companies of the PETROS Plan amounting to 12.93% of the
            salaries of participants in the plan. 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 2003
            year, contributions paid totaled US$ 402 (US$ 311 in 2002), and was
            deducted from the balance of the provision for benefit obligation
            established at December 31, 2003. In the 2003 and 2002 financial
            years, these contributions were included in the cost of operations.

            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 arising from the difference between
            the actuarial assumptions and the fair value of plan assets are
            respectively recorded as "amounts not recognized as net periodic
            pension cost", in shareholders' equity. These gains and losses are
            amortized during the average remaining service period of the active
            employees of approximately 15 years at December 31, 2003, in
            accordance with the procedure established by SFAS 87.

            The relation between contributions by the sponsors and participants
            of the PETROS Plan, considering only those attributable to the
            Company and subsidiaries in the 2003 financial year, was 1.01 (0.94
            in 2002). The Company's best estimate of contributions expected to
            be paid in 2004 respective to the pension plan approximates US$ 122.

            The Fundacao Petrobras de Seguridade Social (PETROS) and the current
            benefits plan (the PETROS Plan)--Continued

            According to Constitutional Amendment No. 20, 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
            SFAS 87), must be equally shared between the sponsor and the
            participants.

            Therefore, in the event that the deficit computed for December 31,
            2003 in accordance with the projected credit unit method (SFAS 87),
            is reflected as a technical deficit in the methods adopted by the
            PETROS Plan, and results in additional financial contributions,
            these additional required contributions shall be divided equally
            between the Company and the participants.

            In addition, PETROS has agreed to provide certain financing for the
            continued development of the Albacora oil and gas field located in
            the Campos Basin (see Note 14).

            The Company uses 6% as the expected long-term rate of return on
            PETROS' assets. The PETROS' portfolio of investments as of December
            31, 2003 was comprised of 71% securities, 50% of which were
            held-to-maturity government securities that earn interest at 6%
            annually plus the IPCA (Consumer Price Index) variation and 23% of
            which were Investments Funds that earn interest approximate to the
            CDI (Certificado de Deposito Interbancario, or Interbank Deposit
            Certificate), which has been yielding more than 6% annually. Thus,
            the Company considers a 6% long term interest rate appropriate to
            calculate the expected return on assets, as such aligns with the
            composition of the PETROS' asset portfolio.

            PETROS intends to change its investment strategy for the 2004-2008
            years to reflect the evolution of and opportunities expected in the
            Brazilian economy for 2004 and beyond. PETROS will continue to
            maintain plan assets in various sectors, but percentages by asset
            type are expected to differ depending on yield's achievable in the
            market while minimizing risk exposure.

            PETROS has a significant volume of investments in government
            securities, mainly NTN-B bonds, which by an agreement with the
            Supplementary Social Security Department will be held-to-maturity.
            Thus, the percentage of assets allocated in this investment will
            remain the same over the short term.

            PETROS--Continued

            PETROBRAS VIDA plan

            In May of 2001, the Board of Directors of PETROBRAS approved the
            creation of a mixed social security plan, for current and new
            employees, based on defined contribution formula for programmable
            benefits and a defined benefit formula for risk benefits.

            The new plan, PETROBRAS VIDA, was approved by the Coordination and
            Control Department of State Companies (DEST) and by the
            Supplementary Social Security Department (SPC) in October of 2001,
            and ratified by PETROBRAS Board of Directors.

            The migration process of participants in the current plan to
            PETROBRAS VIDA has been temporarily suspended pursuant to a Federal
            Justice ruling. Therefore the impact of migration to the new plan
            will only be computed and recognized in the Company's financial
            statements in accordance with the requirements of SFAS No. 88 -
            Employers' Accounting for Settlements and Curtailments of Defined
            Benefit Pension Plans and for Termination Benefits ("SFAS 88"), when
            the issues being litigated have been resolved and the migration
            process finalized.

            In August of 2002, pursuant to closure of the PETROS Plan, PETROBRAS
            took out a group life insurance policy to cover employees beginning
            employment with the Company subsequent to closure of the PETROS
            plan; this policy will remain in effect until a new private pension
            plan is implemented.

            TRANSPETRO

            TRANSPETRO maintains a defined-contribution private pension scheme
            with PETROS called Plano TRANSPETRO, which receives monthly
            contributions equivalent to 5.32% of the payroll of the members and
            is equal to the contributions made by the participants.

            PETROS--Continued

            PETROBRAS ENERGIA - PEPSA

            Defined contribution plan

            Petrobras Energia sponsors a defined contribution plan applicable to
            all of its employees with salaries above a specified level. Through
            this plan, Petrobras Energia provides additional funds at amounts
            equivalent to contributions made by employees which are in excess of
            legally required amounts. These funds are recognized in accordance
            with the accrual method of accounting. Due to significant changes in
            the macroeconomic scenario in 2002 and the uncertainties with regard
            to the Argentine economic conditions, PEPSA has temporarily
            suspended this benefit as from January of 2002. This benefit will be
            reinstated when a provisional savings means considered adequate to
            this end is identified.

            All employees joining PEPSA prior to May 31, 1995 that have
            participated in the defined contribution plan without interruption
            and that have worked for a required number of years are entitled to
            this benefit. The benefit is based on the latest salary amount paid
            to the employees that participate in the plan, considering the
            number of years worked.

            The plan is of a supplemental nature: the benefit received by the
            employee corresponds to an amount defined in conformity with the
            plan's provisions, after deducting the benefits vested in accordance
            with the contribution plan and the government-sponsored pension
            scheme, so as the aggregate amount of benefits granted to each
            employee under the three plans is equivalent to that defined in the
            plan.

            As from retirement, the employees are entitled to a fixed monthly
            payment.

            The plan requires contributions to a fund, payable by PEPSA and not
            by the employees, who must contribute to the social security system
            based on their total salary. The fund's assets have been transferred
            to a trust and invested mainly in bonds, notes, mutual investment
            funds and fixed term deposits. The Bank of New York is the trustee
            and Watson Wyatt is the managing agent. PEPSA determines the
            liability relating to this plan using actuarial calculation methods.

      (c)   Health care benefits - "Assistencia Multidisciplinar de Saude" (AMS)


            PETROBRAS and its 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.

            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 annual costs incurred by
            plan participants.

            The actuarial gains and losses arising from the differences between
            the actuarial assumptions and the costs effectively incurred are
            respectively included or excluded when defining the net actuarial
            liability. These gains and losses are amortized over the average
            remaining service period of the active employees.

            For measurement purposes, a 5.82% annual rate of increase in the per
            capita cost of covered health care benefits was assumed upon
            adoption of SFAS 106. The annual rate was assumed to decrease to
            2.7% after 50 years.

            Assumed health care cost trend rates have a significant effect on
            the amounts reported for the postretirement health care plans. A
            one-percentage-point change in assumed health care cost rates would
            have the following effects:

      (d)   Funded status of the plans--Continued

            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. As of December 31, 2002, the Company decided
            to change the assumptions related to the estimate of future
            mortality, adopting a new mortality table (GAM-71) more suitable for
            the evolution observed in the average life expectancy of the
            population made up of Company retired employees.

            The Company and its actuarial consultants had been reviewing the
            basis for estimating the assumed discount rate for its actuarial
            obligations in light of the recent development of a secondary bond
            market in Brazil for high-grade long-term government securities.
            According to the requirements of SFAS 87, and subsequent
            interpretations, the discount rate should be based on current prices
            for settling the pension obligation. Applying the precepts of SFAS
            87 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. Although SFAS 87 offers limited
            guidance, the Company considers it appropriate to use actuarial
            assumptions which include an estimate of long-term inflation; i.e.
            nominal rates. Considering that the rate of return offered on high
            grade long-term government securities, a nominal rate of
            approximately 9.2% at December 31, 2003, the Company has decided not
            to change the discount interest rate that has been used
            historically, as it deems such to be consistent with the
            requirements of SFAS 87, and subsequent interpretations, for
            measurement of defined benefit obligations. The Company may adopt
            different assumptions in the future, which may have a significant
            impact on the amount of pension liability and expense.





18.   Shareholders' equity

      The Company's subscribed and fully paid-in capital at December 31, 2003
      consisted of 634,168,418 common shares and 462,369,507 preferred shares
      and, at December 31, 2002, consisted of 634,168,418 common shares and
      451,935,669 preferred shares. 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 Shareholders' Meeting, held jointly with the General
      Shareholders' Meeting on March 22, 2002, approved the increase of the
      Company's capital stock from US$ 4,834 to US$ 6,220 with the
      capitalization of the revenue reserve constituted in prior years, without
      issuing new shares.

      During the same meeting, PETROBRAS shareholders approved a reform of the
      Company's by-laws to adjust them to the modifications introduced by Law
      No. 10,303, of October 31, 2001. The principal change introduced by the
      new by-laws include an amendment that requires preferred shares to be
      given priority in the case of repayment of capital and the receipt of
      dividends, of at least 3% of the book value of the shares or 5% calculated
      on the portion of capital represented by this class of shares, whichever
      is larger, and participation on an equal footing with common shares in
      capital increases resulting from the incorporation of reserves and income.

      On June 10, 2002 at an Extraordinary Shareholders' Meeting, the Company's
      shareholders approved an amendment to the Company's by-laws, to adjust
      them to the modifications introduced by Law No. 10,438 of April 26, 2002.
      This amendment authorized a change in the corporate purpose of the
      Company, to include activities related with energy and its sale, in
      addition to providing more flexible means of borrowings. The Company is
      also authorized to increase capital, irrespective of an amendment to the
      by-laws, as a result of a resolution by the Board of Directors, up to R$
      30,000 million, by means of issuing up to 200 million shares, such that
      preferred shares do not exceed two-thirds of common shares.

      In a Special Meeting of Preferred Shareholders held on June 10, 2002, the
      Company's shareholders ratified a resolution taken by the Extraordinary
      Shareholders' Meeting authorizing the issue of preferred shares, without
      maintaining proportion with common shares.



18.   Shareholders' equity--Continued

      On December 20, 2002, the Board of Directors approved the Company's share
      buyback program, as facilitated by its by-laws, with the main purpose of,
      defending the price of its share at times when it is undervalued by the
      market. The definition and implementation of the share buyback program is
      not intended to jeopardize the investment program or replace the payment
      of dividends by the Company.

      On January 29, 2003, the Board of Directors of the Company, approved the
      issuance of 9,866,828 preferred shares of the Company in connection with
      the public offer by the Company to acquire publicly traded shares of
      Petrobras Distribuidora - BR, at an issue price of US$ 12.38 (R$ 45.08)
      per share, under the terms of the capital increase approved during the
      meeting of the Board of Directors of the Company held on November 7, 2002.
      As a result, the capital of the Company increased by US$ 122. This
      minority interest acquisition, accounted for as a purchase business
      combination under SFAS No. 141 - Business Combinations ("SFAS 141"), did
      not have a material impact to the financial statements. See also Note 20.

      The Extraordinary Shareholders' Meeting, held jointly with the General
      Shareholders' Meeting on March 27, 2003, approved an increase in the
      Company's capital by capitalizing revenue reserves accrued during previous
      years, to the amount of US$ 912, without issuing new shares, in accordance
      with Art. 169, paragraph 1 of Law No. 6,404/76.

      On May 9, 2003, the Board of Directors of the Company approved the issue
      of 567,010 preferred shares of the Company in connection with the public
      offer by the Company to acquire publicly traded shares of Petrobras
      Distribuidora - BR, at an issue price of R$ 45.08 per share. As a result,
      the capital of the Company increased by US$ 8.

      The management of PETROBRAS will propose to the General Extraordinary
      Meeting, to be held together with the General Ordinary meeting on March
      29, 2004, an increase in the Company's capital to R$ 32,896,138 thousand,
      through the capitalization of revenue reserves accrued during previous
      financial years, in the amount of R$ 13,033,504 thousand, and without the
      issuance of new shares, in accordance with article 169, paragraph 1, Law
      No. 6,404/76. This capitalization will be made in order to bring the
      Company's capital in line with the investment requirements of an oil
      company given intensive use of capital and extended operating cycles.
      Additionally, the Company's management will propose an increase in
      authorized capital from R$ 30,000 million to R$ 60,000 million at the
      General Extraordinary Meeting.



18.   Shareholders' equity--Continued

      Current Brazilian law requires that the Federal Government retain
      ownership of 50% plus one share of the Company's voting shares.

      (a)   Dividends and interest on shareholders' equity

            In accordance with the Company's by-laws, holders of preferred and
            common shares are entitled to a minimum dividend of 25% of annual
            net income as adjusted under Brazilian Corporate Law. 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. The Company paid US$ 212 in dividends during the
            year ended December 31, 2003 (2002 - US$ 602 - 2001 - US$ 424)

            Brazilian corporations are permitted to attribute interest on
            shareholders' equity, which may either be paid in cash or be used to
            increase capital stock. The calculation is based on shareholders'
            equity amounts as stated in the statutory accounting records and the
            interest rate applied may not exceed the Taxa de Juros de Longo
            Prazo (long-term interest rate or the "TJLP") as determined by the
            Brazilian Central Bank. Such interest may not exceed the greater of
            50% of net income or 50% of retained earnings plus revenue reserves.
            Interest on shareholders' equity, is subject to withholding tax at
            the rate of 15%, except for untaxed or exempt shareholders, as
            established by Law No. 9,249/95. The Company paid US$ 731 in
            interest on shareholders' equity during the year ended December 31,
            2003 (2002 - US$ 416 - 2001 - US$ 1,301).

            On November 13, 2003, the PETROBRAS Board of Directors approved the
            distribution of remuneration to shareholders in the form of interest
            on shareholders' equity amounting to R$ 3,290 million (US$ 1,139),
            in accordance with article 8 and 9, of the Company's by-laws,
            article 9 of Law No. 9,249/95 and Decrees No. 2,673/98 and No.
            3,381/00. This provision for interest on shareholders' equity
            resulted in an income tax benefit in the amount of US$ 364.



18.   Shareholders' equity--Continued

      (a)   Dividends and interest on shareholders' equity--Continued

            This remuneration was made available to shareholders at February 13,
            2004, based on the shareholdings on November 25, 2003, corresponding
            to R$ 3.00 (US$ 1.03 calculated by the year-end exchange rate) per
            common and preferred share, and was deducted from the dividend
            calculated on adjusted net income for the 2003 financial year.

            The General Shareholders' Meeting held on March 27, 2003 approved
            the proposed dividends for the 2002 financial year amounting to US$
            781; such amount included US$ 307 which was accrued in the 2002
            financials, and interest on shareholders' equity approved by the
            Board of Directors on January 31, 2003, amounting to US$ 310, and
            the balance of dividends, amounting to US$ 164, both of which amount
            were reflected in the 2003 financial statements. These amounts, paid
            in Brazilian reais, were monetarily restated as from December 31,
            2002 up to the date of payment.

            The dividends proposal submitted by the Board of Directors for
            approval at the General Shareholders' Meeting to be held on March
            29, 2004, amounting to US$ 1,955, corresponding to R$ 5.15 per share
            (US$ 1.78 per share calculated by year-end exchange rate), include
            the portion of interest on shareholders' equity approved by the
            Board of Directors on November 13, 2003, amounting to US$ 1,139,
            corresponding to R$ 3.00 per share (US$ 1.04 per share calculated by
            year-end exchange rate), and also includes the portion of interest
            on equity approved by the Board of Directors on February 13, 2004,
            amounting to US$ 436, corresponding to R$ 1.15 (US$ 0.40 calculated
            by the year-end exchange rate) per common and preferred share, to be
            made available based on the shareholders of record as of March 29,
            2004, which is the intended date of the General Shareholders'
            Meeting that will discuss this subject.

            The balance of dividends (US$ 380) and the additional portion of the
            interest on shareholders' equity (US$ 436) have been excluded from
            the US GAAP financials, but will be paid on a date to be established
            by the General Shareholders' Meeting. These amounts are paid in
            Brazilian reais and will be monetarily restated as from December 31,
            2003 up to the initial date of payment, according to the variation
            in the SELIC rate.



18.   Shareholders' equity--Continued

      (a)   Dividends and interest on shareholders' equity --Continued


            Brazilian law permits the payment of dividends only from retained
            earnings as stated in the statutory accounting records. At December
            31, 2003, the Company had appropriated all such retained earnings.

            In addition, at December 31, 2003, the undistributed reserve in
            appropriated retained earnings, amounting to US$ 9,372, may be used
            for dividend distribution purposes, if so approved by the
            shareholders, however, the Company's stated intent is to use such
            reserve to fund working capital and capital expenditures.

            A withholding tax of 15% was payable on distributions dividends
            earned from January 1, 1994 through December 31, 1995. No
            withholding tax is payable on distributions of dividends earned
            since January 1, 1996.

      (c)   Capital reserves

            o     AFRMM

                  Relates to the Merchant Marine (AFRMM) freight surcharges
                  levied in accordance with relevant legislation. These funds
                  are used to purchase, enlarge or repair vessels of the
                  Company's transport fleet.

            o     Fiscal incentive reserve

                  This reserve consists of investments in tax incentives in the
                  Northeast Investment Fund (FINOR), arising from allocations of
                  part of the Company's income tax.

      (d)   Appropriated retained earnings

            Brazilian Law and the Company's by-laws require that certain
            appropriations be made from retained earnings to reserve accounts
            annually. The purpose and basis of appropriation to such reserves is
            as follows:

            o     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.

            o     Undistributed earnings reserve

            This reserve is established in accordance with Article 196 of Law
            No. 6,404/76 to fund the Company's annual investment program. For
            the year ended December 31, 2002, the Company's management retained
            US$ 1,834 of which US$ 1,831 relates to net income for the year and
            US$ 3 to the remaining balance of retained earnings, to fund the
            Company's capital expenditure budget for 2003. This proposal was
            approved at the General Shareholders' Meeting held on March 27,
            2003.

      (d)   Appropriated retained earnings--Continued

            o     Undistributed earnings reserve--Continued

                  The proposal for appropriation of income for the year ended
                  December 31, 2003 includes a retention of earnings in the
                  amount of US$ 4,603, of which US$ 3,773 relates to net income
                  for the year and US$ 830 to the remaining balance of retained
                  earnings, to be approved by the General Shareholders' Meeting
                  to be held on March 29, 2004. This proposal is intended to
                  cover partially the annual investment program established in
                  the capital budget for 2004.

            o     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
                  by-laws.

19.   International acquisitions

      (a)   Acquisition of an interest in Petrobras Energia Participaciones S.A.
            - PEPSA - (formerly known as Perez Companc S.A.) and Petrolera Entre
            Lomas S.A. - PELSA (formerly known as Petrolera Perez Companc S.A.)


            On October 17, 2002, the Company signed the Final Share Acquisition
            Agreement with the Perez Companc family and the Fundacion Perez
            Companc, completing the acquisition of a controlling interest of
            Perez Companc S.A. (currently known as Petrobras Energia
            Participaciones S.A - PEPSA), and Petrolera Perez Companc S.A.
            (currently known as Petrolera Entre Lomas S.A. - PELSA). In October
            of 2002, in accordance with Argentine legislation, the necessary
            documentation was submitted to the Argentine antitrust agency (CNDC
            - Comision Nacional de Defensa de la Competencia) in order to obtain
            approval for the transaction.



19.   International acquisitions--Continued

      (a)   Acquisition of an interest in Petrobras Energia Participaciones S.A.
            - PEPSA - (formerly known as Perez Companc S.A.) and Petrolera Entre
            Lomas S.A. - PELSA (formerly known as Petrolera Perez Companc
            S.A.)--Continued

            On May 13, 2003, the Argentine antitrust agency (Comision Nacional
            de Defensa de la Competencia), an agency reporting to the Argentine
            Secretariat of Competition, Deregulation and Consumer Protection
            (Secretaria de la Competencia, la Deregulacion y la Defensa del
            Consumidor), approved the purchase of 58.62% of the capital stock of
            PEPSA and 39.67% of the capital stock of PELSA capital stock by
            PETROBRAS Participacoes S.L., a company controlled by PETROBRAS. As
            a result of the purchase of a 39.67% interest in the capital stock
            of PELSA, together with the purchase of 58.62% of PEPSA's interest
            in the capital stock of PELSA, the Company has a controlling
            interest in PELSA equal to 50.73% and thus has consolidated the
            entity.

            The purchase price to be paid for PEPSA and PELSA was based on an
            economic valuation model of expected future earnings of those
            companies, which considered relevant factors, including the
            potential effects of the economic situation of Argentina. The
            Company paid US$ 739 in cash and US$ 338 in bonds to the Perez
            Companc family for the shares of PEPSA and PELSA.

            The acquisition was consummated principally to expand PETROBRAS
            operations into geographical markets where the Company had little
            activity. Through the acquisition of PEPSA and PELSA, PETROBRAS was
            able to gain immediate access to the Argentine market and brand
            recognition. The goodwill of US$ 183 generated by the transaction is
            attributed principally to downstream activities.

            The acquisition of PEPSA and PELSA was recorded using the purchase
            method of accounting and the financial statements of PEPSA and PELSA
            were included in the consolidated PETROBRAS financial statements,
            beginning on May 13, 2003. The purchase price for PEPSA and PELSA
            was allocated based on the fair market value of the assets acquired
            and the liabilities assumed as of the acquisition date as determined
            by independent appraisers.

            Lomas S.A. - PELSA (formerly known as Petrolera Perez Companc
            S.A.)--Continued

            PEPSA operates principally in the areas of oil field exploration and
            production, refining, transport and commercialization, electricity
            generation, transmission and distribution, and petrochemicals. Its
            activities are primarily based in Argentina, but PEPSA also operates
            in Bolivia, Brazil, Ecuador, Peru and Venezuela. PELSA operates
            primarily in the oil and gas exploration and production industry in
            Argentina.

            The following unaudited pro forma summary financial information
            presents the consolidated results of operations as if the
            acquisition of PEPSA and PELSA had occurred at the beginning of the
            periods presented.

      (b)   Acquisition of Petrolera Santa Fe

            On October 24, 2002, the Company completed the acquisition of 100%
            of Petrolera Santa Fe Southern Cone, Inc., a holding company
            incorporated in the British Virgin Islands, parent company of
            Petrolera Santa Fe S.R.L (Santa Fe), an Argentine oil and gas
            exploration company, for US$ 90, paid in cash on the same date. The
            purchase price was less than the estimated fair market value of the
            net assets acquired, resulting in a reduction in the acquisition
            value assigned to Santa Fe's long-lived assets. In 2002, Santa Fe
            produced approximately 10.2 thousand barrels of oil equivalents per
            day. The acquisition did not have significant effects on results of
            operations on a pro-forma basis.


20.   Petrobras Distribuidora - BR

      On November 7, 2002, the Board of Directors of the Company approved a
      public offer by the Company to acquire the publicly traded shares of
      Petrobras Distribuidora S.A. - BR, to cancel its quoted company
      registration by means of an exchange for preferred share to be issued by
      the Company.

      In addition the Board of Directors approved the valuation appraisal of BR
      that determined the value of R$ 45.40 (US$ 11.66) for each 1,000 share lot
      of BR stock, the valuation appraisal by the Company that established a
      value of R$ 64.90 (US$ 16.66) for each share issued by the Company
      together with the swap ratio of the Company and BR shares at the rate of
      0.7 PETROBRAS shares for 1,000 BR shares, which will be agreed together
      with a premium, defined by the specific formula.

      On January 29, 2003, a public auction was held in which implementation of
      the condition for canceling the registration of the quote company of BR
      was verified. On February 5, 2003, CVM cancelled the registration of the
      quoted company of BR.



21.   Accounts - temporary agreement on price stabilization in Argentina

      In January 2003, pursuant to government actions seeking to stabilize the
      economic environment in Argentina, the hydrocarbon producing and refining
      companies signed a temporary agreement aimed at stabilizing the prices of
      crude oil, gasoline and diesel oil in the Argentine market. This
      agreement, considering renewals, extends to February 29, 2004. Under this
      agreement, deliveries of crude oil must be billed and paid based on a
      reference WTI (West Texas Intermediate) price of US$ 28.50 per barrel.
      Positive or negative differences between the actual WTI, up to the limit
      of US$ 36.00 per barrel, and the reference price are to be realized based
      on amounts generated in periods during which the actual WTI price is lower
      than US$ 28.50 per barrel. As long as average market WTI prices remain
      higher than the reference price, the refining companies will, otherwise,
      record a liability to be realized when the WTI price is lower than the
      reference price. At December 31, 2003, the amount payable by Argentine
      companies within the PETROBRAS system related to the price difference on
      the acquisition of crude oil, amounted to US$ 10.

22.   Commitments and contingencies

      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 currently has several contracts to purchase crude oil, diesel
      fuel and other oil products, which require the Company to purchase a
      minimum of approximately 147,000 barrels per day at respective current
      market prices.



22.   Commitments and contingencies--Continued

      PETROBRAS provided guarantees to the ANP for the minimum exploration
      program defined in the concession contracts for exploration areas,
      totaling US$ 907. Out of this total, US$ 704 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 at the time where Law No. 9,478 of August 6,
      1997 came into force. For areas whose concessions were obtained by bidding
      from the ANP, PETROBRAS has given bank guarantees totaling US$ 203 through
      December 31, 2003.

      PETROBRAS has guaranteed that it will purchase specified volumes of
      natural gas that run through TBG pipeline.

      In 1993, the Company signed a contract with Yacimentos Petroliferos
      Fiscales Bolivianos, the Bolivian state oil company for the purchase of
      natural gas. Under this contract, the Company is required to purchase 80%
      of the natural gas transported through the Bolivia/Brazil natural gas
      pipeline over a 20 year term at contract prices ranging from US$ 1.07 per
      MMBTU to US$ 1.17 MMBTU, based upon throughput. The pipeline achieved an
      average throughput of 24.64 million cubic meters per day during 2003.

      The Company has exclusive supply contracts with certain service stations.
      These contracts are typically for seven years and require the Company to
      sell product at market prices.



22.   Commitments and contingencies--Continued

      (a)   Litigation

            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,
            2003 and 2002, the respective claims by type are as follows:


                                                                                 As of December 31,

            As of December 31, 2003 and 2002, in accordance with Brazilian law,
            the Company had paid US$ 543 and US$ 290, 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.

            The Company is a party to several contracts related to the
            acquisition and upgrade of production Platform P-36, which was lost
            in its entirety in 2001. Pursuant to those contracts, the Company
            had an obligation to pay the insurance proceeds to a Security Agent
            for distribution according to specified clauses established in the
            contracts. The Company contends that it is entitled to the insurance
            proceeds under the contractual arrangements, and other parties
            contend that they are also entitled to such proceeds. The issue is
            subject to international proceedings in a British court. Pending
            determination of the issue by the international court, the Company
            committed to deposit cash collateral in the amount of US$ 175, in
            order to facilitate the issuance of a guarantee by a Security Agent,
            for the payment of creditors. At December 31, 2003, this amount was
            included in the balance sheet as restricted deposits for legal
            proceedings and guarantees.

      (a)   Litigation--Continued

            On May 28, 1981, Kallium Mineracao S.A. brought an action against
            Petromisa, a former subsidiary of PETROBRAS, in the Federal Court of
            the State of Rio de Janeiro alleging damages of approximately US$
            450 relating to the rescission of a contract to develop a potassium
            salt mine. On August 10,1999, a decision was handed down that
            considered most of the plaintiff's petitions to be without grounds
            (losses, damages and loss of profit), requiring only the Company to
            reimburse "all expenses incurred as a result of the prospecting
            research" carried out, in accordance with amounts to be calculated
            in the final award. No award for loss of profit was established in
            the decision. In September of 1999 both parties filed appeals with
            the appeals court in the state of Rio de Janeiro. Based on the
            opinion of its legal advisers, management does not expect an
            unfavorable outcome in this case and considers the risk of loss with
            respect to this lawsuit to be remote.

            On August 8, 1993, Industria Bahiana de Adubos, Importacao e
            Exportacao Ltda. filed a lawsuit against the Company in the State
            Court of Bahia claiming approximately US$ 129 in damages. The claim
            is based upon the Company's refusal to sell fertilizers to the
            plaintiff due to the plaintiff's payment default under prior
            contracts with the Company. The plaintiff claims that such refusal
            harmed its financial condition and, ultimately, caused its
            bankruptcy. On December 9, 1993, the trial court decided in favor of
            the plaintiff. However, the Company appealed and the decision was
            reversed by the State Court of Appeals. Subsequently, the plaintiff
            filed a special appeal, which was also found to be without grounds
            on June 25, 2002 by the 3rd Panel of the Appeals Court. This Court
            dismissed the case and the lawsuit was extinguished.

            On November 23, 1992, PORTO SEGURO IMOVEIS 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.

      (a)   Litigation--Continued

            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 of
            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. However, since the
            award would be payable to PETROQUISA and PETROBRAS holds 99.0% of
            its capital, the effective disbursement if the ruling is not
            reversed will be restricted to 25% of the total award. PETROBRAS
            filed an appeal with the State Court of Rio de Janeiro, and received
            a favorable decision from the Third Civil Court on February 11,
            2003, which, by a majority vote, accepted PETROBRAS' appeal to
            reverse the judgment and ruled the plaintiff's case to be without
            grounds, the revising judge's decision that held the case to be
            partially with grounds to reduce the amount of compensation to US$
            1,538 being overruled. Based on its legal counsels advice,
            PETROBRAS' Administration does not expect to obtain an unfavorable
            decision in the case and assesses the risk of loss to be remote.

            The Fisherman's Federation of the State of Rio de Janeiro (FEPERJ)
            filed a civil suit against the Company with the Rio de Janeiro State
            Court for compensation of miscellaneous damages amounting to US$
            224, which it is claiming in the name of its members, as a result of
            the oil spill in Guanabara Bay on January 18, 2000. A decision was
            handed down on February 7, 2002 which ruled the claim partially
            without grounds, rejecting pain and suffering, and requiring the
            Company to pay compensation for material damages and loss of profit
            to be calculated at the award phase. The ruling expressly declares
            that it is not reasonable to consider an award based on the amount
            claimed, since it was without economic base.

      (a)   Litigation--Continued

            Based on its legal counsels opinion, the Company's Administration
            believes it is possible that the Company will not prevail in this
            case, but that any possible negative judgment would be in an amount
            far below the originally filed complaint. As such, the Company
            assesses the risk of loss related to this case as possible.

            The Sao Paulo tax authorities filed a tax suit against the Company,
            alleging that the Company did not pay ICMS levied on interstate
            sales of naphtha. However, during the period in which according to
            the State of Sao Paulo, the Company should have paid the ICMS, the
            Company was subject to a different tax regime (federal) on these
            sales, and for this reason enjoyed a tax holiday. The value of the
            matter in controversy is US$ 60. There is no guarantee that the
            final result of the legal case will be favorable to PETROBRAS, but
            even in the case of an unfavorable ruling, management does not
            believe that the award could have a material negative impact on the
            financial position of PETROBRAS. The Company assesses its risk of
            loss in the matter as possible.

            PETROBRAS is a defendant in four labor claims filed by the UNIONS OF
            PETROLEUM WORKERS of three federal states (Rio de Janeiro, Sao Paulo
            and Sergipe), alleging that official inflation rates for 1987, 1989
            and 1990 (understatement of the official inflation rate - Bresser,
            Summer and Collor Plans) were not fully included in the workers'
            salaries.

            The lawsuits are at different stages. Based on past favorable
            decisions in similar cases and on a final understanding of the TST,
            management does not expect an unfavorable decision in these suits.
            Three identical cases have been decided in favor of PETROBRAS.
            Management assesses risk of loss to be remote.

            The Company was sued in court by certain small oil distribution
            companies under the allegation that it does not pass on to state
            governments the State Value-Added Tax (ICMS) collected according to
            the legislation upon fuel sales. These suits were filed in the
            states of Goias, Tocantins, Bahia, Para, Maranhao and in the Federal
            District.

      (a)   Litigation--Continued

            Of the total amount related to in legal actions approximately US$
            394 up to December 31, 2003, US$ 32 were effectively withdrawn from
            the Company's accounts as a result of judicial rulings of advance
            relief.

            The Company, with the support of the state and federal authorities,
            has succeeded in stopping the execution of other withdrawals, and is
            making all efforts possible to obtain reimbursement of the amounts
            that were previously withdrawn from its accounts.

      (b)   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.

            The Company made a provision for this contingency in the amount of
            US$ 105 at December 31, 2002, as it considers the chance of success
            in a defense filed against the INSS to be remote.

            On September 29, 2003, the Company received additional INSS tax
            assessments related to the joint liability for irregularities in
            presentation of contractors' documentation related to periods
            subsequent to past notifications. At December 31, 2003 the balance
            of contingencies associated with this joint liability was US$ 193.

            Internally, procedures were revised to improve the inspection of
            contracts and require the presentation of documents, as stipulated
            in the legislation, to substantiate the payment of INSS amounts due
            by contractors. PETROBRAS continues to analyze each tax assessment
            received in order to recover amounts, as permitted through
            administrative processes of the INSS.

      (c)   Tax assessments - internal revenue service of Rio de Janeiro

            The Internal Revenue Service of Rio de Janeiro filed two Tax
            Assessments against the Company in connection with Withholding Tax
            (IRRF) on foreign remittances of payments related to charter of
            vessels of movable platform types for the years 1998 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%.

            The Company disagrees with the Internal Revenue Service's
            interpretation as to charter contracts, given that the Federal
            Supreme Court has already ruled that, in the context of its judgment
            with respect to the IPI (Federal VAT) tax, offshore platforms are to
            be classified as sea-going vessels. Additionally, the 1994 and 1999
            Income Tax Regulations support the "non-taxation" (RIR/1994) and the
            "zero tax rate" (RIR/1999) for the remittances in question.

            On June 27, 2003, the Internal Revenue Service served a tax
            assessment notice on the Company amounting to R$ 3,064 million (US$
            1,066) covering the period from 1999 to 2002. Using the same
            arguments, on February 17, 2003, another tax assessment notice had
            already been issued for R$ 93 million (US$ 32) with respect to 1998,
            against which, on March 20, 2003, the Company filed an appeal.
            According to the fiscal authorities, the Company should have
            withheld that tax, incident on remittances made to abroad for
            payment of the hiring of vessels of the mobile platform type, used
            in oil exploration and production.

      (c)   Tax assessments - internal revenue service of Rio de
            Janeiro--Continued

            PETROBRAS has defended itself against these tax assessments: i) the
            smaller in value has been confirmed by the first administrative
            level, and the corresponding appeal has been already filed by the
            Company, and waits judgment; ii) no first level decision has been
            issued so far with regard to the other one, with greater value.
            Based on its legal counsels advice, the Company's Administration
            does not expect to obtain an unfavorable decision in this case, and
            thus has assessed risk of loss to be remote.

      (d)   Environmental matters

            The Company is subject to various environmental laws and
            regulations. These laws regulate the discharge of oil, gas or other
            materials into the environment and may require the Company to remove
            or mitigate the environmental effects of the disposal or release of
            such materials at various sites.

            During 2000 the Company implemented an environmental excellence and
            operational safety program - PEGASO - (Programa de Excelencia em
            Gestao Ambiental e Seguranca Operacional). Scheduled to be concluded
            in December 2003, the Company made expenditures of approximately US$
            2,400 from 2000 to December 31, 2003 under this program.

            During the years ended December 31, 2003 and 2002 the Company made
            expenditures of approximately US$ 766 and US$ 677 respectively,
            under this program, including US$ 225 and US$ 234 through the
            Programa de Integridade de Dutos (Pipeline Integrity Program)
            through which it conducts inspections of, and improvements to, the
            Company's pipelines.

            The Company believes that future payments related to environmental
            clean up activities resulting from these incidents, if any, will not
            be material.

      (d)   Environmental matters--Continued

            On January 18, 2000, a pipeline from one of the Company's terminals
            to a refinery in the Guanabara Bay ruptured, causing a release of
            crude oil into the bay. On January 19, 2001, the Rio de Janeiro
            State Prosecutor filed a criminal lawsuit against the Company. The
            Company is contesting the legal basis for the criminal lawsuit.
            Additionally, the Federal Prosecutor has filed criminal lawsuits
            against the former president of the Company (that finished) and 9
            other employees. The Company cannot predict if the outcome of these
            proceedings will have a material adverse effect on the financial
            condition, results of operations or cash flows of the Company.

            In addition, as a result of the spill, on January 27, 2000, the
            National Council for the Environment enacted a resolution that
            obligated the Instituto Brasileiro do Meio Ambiente e dos Recursos
            Naturais Renovaveis (IBAMA), state environmental agencies and local
            environmental agencies and non-governmental agencies to evaluate the
            control and prevention measures and environmental licensing status
            of all industrial facilities for the production of oil and oil
            products in Brazil. This resolution also mandated that the Company
            perform an independent environmental audit of all of our industrial
            installations located in the State of Rio de Janeiro.

            Since 2000, the Company implemented independent environmental audits
            in all of the Company's plants located in Brazil that was concluded
            during December of 2003. The Company implemented 80% of the auditors
            recommendations and intend to implement the remaining 20% during
            2004.

            On July 16, 2000, an oil spill occurred at the Presidente Getulio
            Vargas refinery releasing crude oil in the surrounding area. The
            Federal and State of Parana Prosecutors have filed a civil lawsuit
            against the Company seeking US$ 1,176 in damages, that have already
            been contested by the Company. Additionally, there are two other
            actions pending, one by the Instituto Ambiental do Parana (Parana
            Environmental Institute) and by another civil association called
            AMAR that have already been contested by the Company. The Company
            cannot predict whether these proceedings will have a material
            adverse effect on the financial condition, results of operations or
            cash flow of the Company.

            On November 4, 2000, the Cypriot flag vessel Vergina II chartered by
            PETROBRAS collided with the south pier at the Company's Almirante
            Barroso terminal in Sao Sebastiao and spilled oil in the Sao
            Sebastiao canal. As a result of the accident, the Company was fined
            approximately US$ 30 by various local environmental agencies. The
            Company is currently contesting these fines.

            On February 16, 2001, the Company's Araucaria-Paranagua pipeline
            ruptured and as a result fuel oil was spilled into the Sagrado,
            Meio, Neves and Nhundiaquara Rivers located in the state of Parana.
            As a result of the accident, the Company was fined approximately US$
            80 by the Instituto Ambiental do Parana (Parana Environmental
            Institute), which the Company is contesting through administrative
            proceedings.

            On March 15, 2001, a spill resulting from the accident involving the
            P-36 platform occurred, causing a release of diesel fuel and crude
            oil. The Company was fined by the Brazilian Environmental Institute
            (IBAMA) US$ 3 in April of 2001 for the spill and improper use of
            chemicals to disperse the oil. The Company is currently contesting
            these fines.

            On May 12, 2003, the rupture of a connection socket on a production
            line at well FZB-71, on the Belem Farm field, in the city of
            Aracati-CE, resulted in the spill of approximately 7 (seven)
            thousand liters of oil at an area located far from any communities
            or water sources. The Company's Contingency Plan was immediately
            activated and cleaning work for the area was carried out. PETROBRAS
            was charged with a penalty of US$ 0.04 by the Environment
            Superintendency of the State of Ceara (Semace) and up to 90% of this
            amount can be reduced by compliance with a Commitment Term entered
            into with the referred environmental entity.

      (d)   Environmental matters--Continued

            On June 3, 2003, a fault in the connection of one of the unloading
            arms of vessel Nordic Marita, anchored at the Maritime Terminal
            Almirante Barroso (Tebar), in Sao Sebastiao, on the North coast of
            Sao Paulo, caused a spill of approximately 27 thousand liters of oil
            from Campos Basin. As a result of this accident, PETROBRAS was
            charged with a penalty of US$ 0.17 by the Brazilian Institute for
            the Environment and Renewable Resources (IBAMA) and of US$ 0.12 by
            Basic Sanitation, Technology and Environment Protection Agency of
            the State of Sao Paulo (CETESB). An appeal was filed against both
            charges based on the understanding that the Company acted in the
            most efficient possible manner in order to minimize possible impacts
            on the environment.

            On August 26, 2003, the rupture of a pipeline between Transpetro's
            terminal in Cabiunas (Macae) and Duque de Caxias Refinery caused the
            spill of 20 (twenty) liters of oil in an area of the city of
            Cachoeiras de Macacu. The Company immediately determined that the
            oil located in the service area of the pipeline should be removed,
            and took preventive measures to protect a creek, near to the
            Soarinhos River, with checks and oil-absorbing materials. In spite
            of the effective procedures adopted by PETROBRAS and the non-absence
            of environmental damages, the Company received a fine from IBAMA in
            the amount of US$ 0.69, but filed an administrative proceeding with
            this entity.

            The Company's management considers that any expenses incurred to
            correct or mitigate possible environmental impacts should not have a
            significant effect on operations or cash flows.

      (e)   Minimum operating lease payments

            The Company is committed to make the following minimum payments
            related to operating leases as of December 31, 2003:

            2004                                                       1,008
            2005                                                       1,127
            2006                                                         784
            2007                                                         237
            2008                                                         200
            2009 and thereafter                                        3,065
                                                                   ---------
            Minimum operating lease payment commitments                6,421
                                                                   =========

            The Company paid US$ 1,205, US$ 1,355, and US$ 1,284 in rental
            expense on operating leases at December 31, 2003, 2002 and 2001,
            respectively.

23.   Derivative instruments, hedging and risk management activities

      The Company is exposed to a number of market risks arising from the normal
      course of business. Such market risks principally involve the possibility
      that changes in interest rates, 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
      an overall risk management policy that is developed under the direction of
      the Company's executive officers.

      The Company may use derivative and non-derivative instruments to implement
      its overall 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 adverse effect on the value of a
      financial instrument that results from a favorable change 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.



23.   Derivative instruments, hedging and risk management activities--Continued

      (a)   Foreign currency risk management

            The Company's foreign currency risk management strategy may involve
            the use of derivative instruments to protect against foreign
            exchange rate volatility, which may impair the value of certain of
            the Company's obligations. The Company currently uses zero cost
            foreign exchange collars to implement this strategy.

            During 2000, the Company entered into three zero cost foreign
            exchange collars to reduce its exposure to variations between the
            U.S. Dollar and the Japanese Yen, and between the U.S. Dollar and
            EURO relative to long-term debt denominated in foreign currencies
            with a notional amount of approximately US$ 470. The Company does
            not use hedge accounting for these derivative instruments.

            These collars establish a ceiling and a floor for the associated
            exchange rates. If the exchange rate falls below the defined floor,
            the counterparties will pay to the Company the difference between
            the actual rate and the floor rate on the notional amount.
            Conversely, if the exchange rate increases above the defined
            ceiling, the Company will pay to the counterparties the difference
            between the actual rate and the ceiling rate on the notional amount.
            The contracts expire upon the maturity date of each note.

            As of December 31, 2002 and 2001, the Company had a fair value
            obligation of US$ 80 and US$ 119, respectively, associated with its
            EURO and Japanese Yen zero cost collar contracts. The Yen zero cost
            collar contracts were settled on September 8, 2003, with a cash
            payment of US$ 68.

            As of December 31, 2003 the Company had a fair value asset of US$ 26
            associated with its Euro zero cost collar contracts.



23.   Derivative instruments, hedging and risk management activities--Continued

      (b)   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 primarily consist of futures
            contracts traded on stock exchanges and options and swaps entered
            into with major financial institutions. The futures contracts
            provide economic hedges to anticipated crude oil purchases and
            sales, generally forecast to occur within a 30 to 360 day period,
            and reduce the Company's exposure to volatile commodity prices.

            The Company's exposure on these contracts is limited to the
            difference between contract value and market value on the volumes
            hedged. Crude oil future contracts are marked to market and related
            gains and losses are recognized currently into earnings,
            irrespective of when physical crude sales occur. For the years ended
            December 31, 2003, 2002 and 2001, the Company consummated commodity
            derivative transaction activities on 72.47%, 42.01% and 21.20%,
            respectively, of its total import and export traded volumes.

            The open positions on the futures market, compared to spot market
            value, resulted in recognized losses of US$ 2, US$ 4 and US$ 6
            during the years ended December 31, 2003, 2002 and 2001,
            respectively.

            A long-term operation was executed on January of 2001 by the sale of
            put options for 52 million barrels of West Texas Intermediate (WTI)
            oil over a period extending from 2004 to 2007, with the objective to
            obtain price protection for this quantity of oil and to provide the
            funding institutions of the Barracuda/Caratinga project with a
            minimum guaranteed margin to cover the debt servicing. The puts were
            structured to ensure that the financial institutions participating
            in the financing of the development of the fields receive the price
            required to generate the minimum required return on investment. The
            Company accounts for the put options on a mark to market basis.
            During 2003, 2002 and 2001, the Company realized a net gain of US$ 7
            and US$ 8 and US$ 5, respectively.



23.   Derivative instruments, hedging and risk management activities--Continued

      (b)   Commodity price risk management--Continued

            The fair value of oil products is based on usual market conditions,
            at values prevailing at the closing of the period, considered
            relevant for underlying quotations. Option contracts are valued
            using the Black & Scholes model, considering parameters advised by
            financial institutions of international reputation.

      (c)   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, 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 Brazilian
            Central Bank. The Company currently does not utilize derivative
            financial instruments to manage its exposure to fluctuations in
            interest rates. However, the Company has been studying various forms
            of derivatives to reduce exposure to interest rate fluctuations and
            may use these financial instruments in the future.

      (d)   Risk Management activity at PEPSA

            PEPSA also uses derivative instruments such as options, swaps and
            others, mainly to mitigate the impact of changes in crude oil
            prices, interest rates and future exchange rates. Such derivative
            instruments are designed to mitigate specific exposures, and are
            assessed periodically to assure high correlation of the derivative
            instrument to the risk exposure identified and to assure that the
            derivative is highly effective in offsetting changes in cash flows
            inherent in the covered risk. PEPSA qualifies for hedge accounting
            treatment for its crude oil derivative instruments and its interest
            rate swap derivative instruments.



23.   Derivative instruments, hedging and risk management activities--Continued

      (d)   Risk Management activity at PEPSA--Continued

            PEPSA consummated commodity derivative transactions, referenced to
            WTI, for 40% of its total sales volume (corresponding to 11,963
            thousand boe) at December 31, 2003. The operations settled in the
            year generated a loss in the approximate amount of US$ 67. At
            December 31, 2003, the open positions on the futures market, when
            compared to their market value, represented a negative result of
            approximately US$ 187, if liquidated on that date. These
            transactions were accounted for as cash flow hedges in accordance
            with SFAS No. 133 - Accounting for Derivative Instruments and
            Hedging Activities ("SFAS 133").

            Additionally, PEPSA holds an interest rate contract to manage the
            volatility of the LIBOR rate implied in a Class C negotiable
            instrument, establishing the respective interest rate at 7.93%
            annually. If this instruments were to be liquidated, considering the
            rates used at the date, a net loss of approximately US$ 6 would be
            recorded. This contract qualifies for hedge accounting in accordance
            with SFAS 133.

24.   Financial instruments

      In the normal course of its business, the Company uses various types of
      financial instruments. These instruments include recorded assets and
      liabilities, and also items such as derivatives, which principally involve
      off-balance sheet risk.

      (a)   Concentrations of credit risk

            Substantial portions of the Company's assets including financial
            instruments are located in Brazil and 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 equivalents, government
            securities, the Petroleum and Alcohol Account, trade receivables and
            future contracts.



24.   Financial instruments--Continued

      (a)   Concentrations of credit risk--Continued

            The Company takes several measures to reduce its credit risk to
            acceptable levels. All cash equivalents in Brazil are maintained
            with federal banks in accordance with federal law. 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, 2003 and December 31, 2002, the Company's trade
            receivables were primarily maintained with large distributors.

            As described in Note 11, the National Treasury Notes, NTN-H may be
            used in the settlement of the Petroleum and Alcohol Account.

      (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. 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, the
            Petroleum and Alcohol Account, short-term debt and trade payables
            approximate their carrying values. The fair value for the Company's
            available for sale government securities equals their carrying value
            as disclosed in Note 6.


            The fair values of other long-term receivables and payables do not
            differ materially from their carrying values.

            The Company's debt included US$ 11,888 and US$ 7,346 at December 31,
            2003 and December 31, 2002 and had estimated fair values of US$
            12,690 and US$ 6,791, respectively. The Company's project finance
            obligation, resulting from FIN 46 consolidation was US$ 5,066 at
            December 31, 2003, and had an estimated fair value of US$ 5,115.



24.   Financial instruments--Continued

      (b)   Fair value--Continued

            The call and put portion of the Company's zero cost foreign exchange
            collars at December 31, 2003 have a fair value of US$ 31 and US$ 5,
            respectively (US$ 8 and US$ 88 at December 31, 2002).

25.   Segment information

      The following segment information has been prepared in accordance with
      SFAS No. 131 - Disclosure about Segments of an Enterprise and Related
      information ("SFAS 131"). The Company operates under the following
      segments, which are described as follows:

      o     Exploration and Production - This segment includes the Company's
            exploration, development and production activities in Brazil, as
            well as sales of crude oil and natural gas in the domestic and
            foreign markets.

      o     Supply - This segment includes the Company's refining, logistic,
            transportation and commercialization activities for oil, oil
            products and fuel alcohol. Additionally, this segment includes
            petrochemical and fertilizers division, which includes investments
            in domestic petrochemical companies and the Company's two domestic
            fertilizer plants.

      o     Distribution - This segment represents the oil product and fuel
            alcohol distribution activities conducted by the Company's majority
            owned subsidiary, Petrobras Distribuidora S.A. - BR in Brazil.

      o     Gas and Energy - This segment currently encompasses the
            commercialization and transportation of natural gas produced in or
            imported into Brazil. Additionally, this segment includes the
            Company's domestic electric energy commercialization activities as
            well as investments in domestic natural gas transportation
            companies, state owned natural gas distributors and thermoelectric
            companies.

      o     International - This segment represents the Company's international
            activities conducted in 13 countries, which include Exploration and
            Production, Supply, Distribution and Gas and Energy.



25.   Segment information--Continued

      The items that cannot be attributed to the other areas are allocated to
      the group of corporate entities, especially those linked with corporate
      financial management, overhead related with central administration and
      other expenses, including actuarial expenses related with the pension and
      health-care plans.

      The accounting information by business area was prepared based on the
      assumption of controllability, for the purpose of attribution to the
      business areas only items over which these areas have effective control.

      The main criteria used to record the results and assets by business
      segments are summarized as follows:

      o     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;

      o     The operating income includes net operating revenue, 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;

      o     Assets: covers the assets relating to each segment.

      In periods prior to January 1, 2002, revenue and net income from the gas
      and energy activities of the international segment were added to revenue
      and net income from the exploration and production activities of the
      international segment, as our management did not separate our gas and
      energy operations abroad. In addition, the changes in our accounting
      systems adopted in connection with our new business segment reporting does
      not permit the practicable separation of revenue and cost information for
      those prior periods. We do not believe this classification of the gas and
      energy revenue and net income information materially changes the overall
      segment presentation.

      PETROLEO BRASILEIRO S.A. - PETROBRAS AND SUBSIDIARIES


      SUPPLEMENTARY INFORMATION ON OIL AND GAS EXPLORATION AND PRODUCTION
      ACTIVITIES (UNAUDITED)

      Expressed in Millions of United States Dollars (except when specifically
      indicated)


      In accordance with SFAS 69 - Disclosures About Oil and Gas Producing
      Activities ("SFAS 69"), 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
      Petroleum Law, which liberated the fuel market in Brazil beginning January
      1, 2002.

      The Petroleum Law established a new regulatory framework ending PETROBRAS'
      exclusive agency and enabling competition in all aspects of the oil and
      gas industry in Brazil. As provided in the Petroleum 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 Petroleum 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 "International" geographic includes activities in Angola, Argentina,
      Bolivia, Colombia, Ecuador, Mexico, Nigeria, Peru, The United States of
      America and Venezuela. The Company has immaterial non-consolidated
      companies involved in exploration and production activities; the amounts
      related to such are in the line item titled "Company's share of
      unconsolidated affiliates".



      (i)   Capitalized costs relating to oil and gas producing activities

            The following table summarizes capitalized costs for oil and gas
            exploration and production activities with the related accumulated
            depreciation, depletion and amortization, and asset retirement
            obligation assets:

      (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 ending December 31, 2003, 2002 and 2001 are
            shown in the following table. The Company transfers substantially
            all of its Brazilian crude oil and gas production to the supply
            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
            after January 1, 2002, when full price deregulation began. 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 SFAS 69, 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 2003, 2002 and 2001 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 the estimated quantities of crude
            oil, natural gas and natural gas liquids which geological and
            engineering data demonstrate with reasonable certainty to be
            recoverable in future years from known reservoirs under existing
            economic and operating conditions. Proved reserves do not include
            additional quantities recoverable beyond the term of the concession
            or contract, or that may result from extensions of currently proved
            areas, or from application of secondary or tertiary recovery
            processes not yet tested and determined to be economic.

            Proved developed reserves are the quantities expected to be
            recovered from existing wells with existing equipment and operating
            methods. Proved undeveloped reserves are those volumes which are
            expected to be recovered as a result of future investments in
            drilling, re-equipping existing wells and installing facilities
            necessary to deliver the production from these reserves.





      (iv)  Reserve quantities information--Continued

            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.

            A summary of the annual changes in the proved reserves of crude oil
            and natural gas follows:

      (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 SFAS 69. Estimated future cash
            inflows from production in Brazil are computed by applying year-end
            prices based upon the Company's internal pricing methodology for oil
            and gas to year-end quantities of estimated net proved reserves.
            Estimated future cash inflows from production related to the
            Company's International segment are computed by applying year-end
            prices 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 information provided does not represent management's estimate of
            PETROBRAS' expected future cash flows or value of proved oil and gas
            reserves. Estimates of proved reserve quantities are imprecise and
            change over time as new information becomes available. Moreover,
            probable and possible reserves, which may become proved in the
            future, are excluded from the calculations.





      (v)   Standardized measure of discounted future net cash flows relating to
            proved oil and gas quantities and changes therein--Continued

            The arbitrary valuation prescribed under SFAS 69 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.
