REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
 PETRÓLEO BRASILEIRO S.A. - PETROBRAS
 1.
    
    We have audited the accompanying consolidated balance sheet of PETRÓLEO BRASILEIRO S.A -
PETROBRAS and its subsidiaries as of December 31, 2005, and the related consolidated
statements of income, changes in shareholders equity and cash flows, for each of the two
years in the period ended December 31, 2005. 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 audits.2.
    
    We conducted our audits in accordance with the standards of the Public Company Accounting
Oversight Board (United States). Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of material
misstatement. We were not engaged to perform an audit of the Companys internal control over
financial reporting. Our audits included consideration of internal control over financial
reporting as a basis for designing audit procedures that are appropriate in the circumstances,
but not for the purpose of expressing an opinion on the effectiveness of the Companys
internal control over financial reporting. Accordingly, we express no such opinion. An audit
also includes examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation. We believe
that our audits provide a reasonable basis for our opinion.3.
    
    In our opinion, the financial statements referred to above present fairly, in all material
respects, the consolidated financial position of PETRÓLEO
BRASILEIRO S.A. - PETROBRAS and its
subsidiaries as of December 31, 2005, and the consolidated results of their operations and
their cash flows for each of the two years in the period ended December 31, 2005, in
conformity with U.S. generally accepted accounting principles.

AND SUBSIDIARIES
 
 
 
 1.
    
    The Company and its OperationsPETRÓLEO 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 products, 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.

    Summary of Significant Accounting PoliciesIn 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.Certain prior years amounts have been reclassified to conform to current year presentation
standards. These reclassifications had no impact on the Companys net income.
 (a)
    
    Basis of financial statements preparationThe accompanying consolidated financial statements of PETRÓLEO BRASILEIRO S.A. -
PETROBRAS (the Company) have been prepared in accordance with accounting principles
generally accepted in the United States of America (U.S. GAAP) and the rules and
regulations of the Securities and Exchange Commission (SEC). U.S. GAAP differs in certain
respects from 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 and Exchange Commission (CVM).

    Summary of Significant Accounting Policies(Continued)
 (a)
    
    Basis of financial statements preparation(Continued)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 and all Brazilian subsidiaries is the Brazilian Real. The functional
currency of PIFCo and certain of the special purpose companies is the U.S. dollar, and
the functional currency of Petrobras Energia Participaciones S.A.  PEPSA is the
Argentine Peso.The Company has translated all assets and liabilities into U.S. dollars at the current
exchange rate (R$2.138 and R$2.3407 to US$1.00 at December 31, 2006 and 2005,
respectively), and all accounts in the statements of income and cash flows (including
amounts relative to local currency indexation and exchange variances on assets and
liabilities denominated in foreign currency) at the average rates prevailing during the
year. The net translation gain in the amount of US$3,230 in 2006 (2005  US$3,107 and
2004  US$1,911) resulting from this remeasurement process was excluded from income and
presented as a cumulative translation adjustment (CTA) within Accumulated Other
Comprehensive Income in the consolidated statements of changes in shareholders equity.(b)
    
    Basis of consolidationThe 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(R).

    Costs incurred in oil and gas producing activitiesThe costs incurred in connection with the exploration, development and production of
oil and gas are recorded in accordance with the successful efforts method. This
method requires that costs the Company incurs in connection with the drilling of
developmental wells and facilities in proved reserve production areas and successful
exploratory wells be capitalized. In addition, costs the Company incurs in connection
with geological and geophysical activities are charged to the statements of income in
the year incurred, and the costs relating to exploratory dry wells on unproven reserve
properties are charged to the statements of income when determined as dry or
uneconomical.
    
    Capitalized costsThe capitalized costs are depreciated based on the unit-of-production method using
proved developed reserves. These reserves are estimated by the Companys geologists
and petroleum engineers in accordance with SEC standards and are reviewed annually, or
more frequently when there are indications of significant changes in the Companys
reserves.
    
    Property acquisition costsCosts of acquiring developed or undeveloped leaseholds including lease bonus,
brokerage, and other fees are capitalized. The costs of undeveloped properties that
become productive are transferred to a producing property account.
    
    Exploratory costsExploratory wells that find oil and gas in an area requiring a major capital
expenditure before production begins are evaluated annually to assure that commercial
quantities of reserves have been found or that additional exploration work is underway
or planned. Exploratory costs related to areas where commercial quantities have been
found are capitalized, and exploratory costs where additional work is underway or
planned continue to be capitalized pending final evaluation. Exploratory well costs
not meeting either of these tests are charged to expense. All other exploratory costs
(including geological and geophysical costs) are expensed as incurred. Exploratory dry
holes are expensed.

    Abandonment costsThe Company makes its annual reviews and revision of its estimated costs associated
with well abandonment and the demobilization of oil and gas production areas,
considering new information about date of expected abandonment and revised cost
estimates to abandon. The changes in estimated asset retirement obligation are
principally related to the commercial declaration of new fields, certain changes in
cost estimates, and revisions to abandonment information provided for non-operated
joint ventures.
    
    Depreciation, depletion and amortizationDepreciation, depletion and amortization of leasehold costs of producing properties
are recorded using the unit-of-production method applied on a field by field basis as
a ratio of proved developed reserves. Production platform under capital lease are
depreciated on a straight-line basis over the estimated useful lives of the platforms.
Depreciation, depletion and amortization of all other capitalized costs (both tangible
and intangible) of proved oil and gas producing properties is recorded using the
unit-of-production method applied on a field by field basis as a ratio of proved
developed reserves produced. The straight-line method is used for assets with a useful
life shorted than the life of the field.

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.

volumetric delivery differences are not significant. Costs and expenses are accounted for
on an accrual basis.(j)
    
    Income taxesThe 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.The Company records the tax benefit of all net operating losses as a deferred tax asset
and recognizes a valuation allowance for any part of this benefit which management
believes will not be recovered against future taxable income using a more likely than
not criterion.

    Earnings per shareEarnings 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. As
a result of a 2005 stock split, each American Depositary Share (ADS) for common shares
represents four shares of the Companys common shares or four shares of the Companys
preferred shares.(o)

    Accounting for derivatives and hedging activitiesThe Company applies SFAS No. 133  Accounting for Derivative Instruments and Hedging
Activities, together with its amendments and interpretations, referred to collectively
herein as SFAS 133. SFAS 133 requires that all derivative instruments be recorded in
the balance sheet of the Company as either an asset or a liability and measured at fair
value. SFAS 133 requires that changes in the derivatives fair value be recognized in the
income statement unless specific hedge accounting criteria are met; and the Company
designates. For derivatives designated as accounting hedges, fair value adjustments are
recorded either in the income statements or Accumulated Other Comprehensive Income, a
component of shareholders equity, depending upon the type of accounting hedge and the
degree of hedge effectiveness.

income taxes recognized in an enterprises financial statements and prescribes a
threshold of more-likely-than-not for recognition of tax benefits of uncertain tax
positions taken or expected to be taken in a tax return. FIN 48 also provides related
guidance on measurement, derecognition, classification, interest and penalties, and

    Income TaxesIncome taxes in Brazil comprise federal income tax and social contribution, which is an
additional federal income tax. The statutory enacted tax rates for income tax and social
contribution have been 25% and 9%, respectively for the years ended December 31, 2006, 2005 and
2004.The Companys taxable income is substantially generated in Brazil and is therefore subject to
the Brazilian statutory tax rate. The following table reconciles the tax calculated based upon

    Income Taxes(Continued)Annually PEPSAs management evaluates the recovery of tax loss carryforwards taking into
consideration, among other elements, the projected business profits, tax planning strategies,
temporariness of future taxable income, considering the term of expiration of the loss
carryforwards, the future reversions of the existing temporary differences and the recent-year
tax history. All the evidence available both positive and negative is duly weighted and
considered in the analysis.At December 31, 2006 and 2005, the PEPSAs management partially reversed the tax loss
carryforward allowance booked in prior years recognizing a tax benefit of US$17 and US$63,
respectively. PEPSAs management will continue analyzing the feasibility of recovering the tax
loss carryforwards for which the allowance was recognized.The deferred tax amounts recorded are principally generated through transactions occurring in
Brazil and there are no significant deferred tax amounts from international locations. There
is no netting of taxes between international jurisdictions.The major components of the deferred income tax accounts in the consolidated balance sheet are

    Income Taxes(Continued)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 generated in Brazil
do not expire and are available for offset against future taxable income, limited to 30% of
taxable income in any individual year. PEPSA tax loss carryfoward principally expire in years
beyond 2007, and may be offset against future taxable income without limitation. The following
presents the changes in the valuation allowance for the years ended December 31, 2006, 2005 and

 The Company has not recognized a deferred tax liability of approximately US$190 for the
undistributed earnings of its foreign operations that arose in 2006 and prior years as the
Company considers these earnings to be indefinitely reinvested. A deferred tax liability will
be recognized when the Company no longer demonstrates that it plans to permanently reinvest
the undistributed earnings. As of December 31, 2006 the undistributed earnings of these
subsidiaries were approximately US$560.

 Marketable securities are comprised primarily of amounts the Company has invested in an
exclusive fund, excluding the Companys own securities, which are considered repurchased. The
exclusive fund is consolidated, and the equity and debt securities within the portfolio are
classified as trading or available-for-sale under SFAS 115 based on managements intent.
Trading securities are principally Brazilian bonds, which are bought and sold frequently with
the objective of making short-term-profits on market price changes. Available-for-sale
securities are principally, LCN (Credit Liquid Note) agreements and certain other bonds for
which the Company does not have current expectations to trade actively. Trading securities are
presented as current assets, as they are expected to be used in the near term for cash funding
requirements. Available-for-sale securities are presented as other assets, as they are not
expected to be sold or liquidated within the next twelve months.The Company holds National Treasury Bonds Series P (NTN-P) issued by the Federal Government
which are accounted for as available-for-sale securities in accordance with SFAS 115.

    Accounts Receivable, Net(Continued)At December 31, 2006 and 2005, long-term receivables include US$608 and US$599 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 consultations with legal advisers, the Companys management has determined that these
payments can be reimbursed, since they represent BRASOILs rights with respect to the
contractors, for which reason judicial action was filed with international courts to seek
reimbursement. However, as a result of the uncertainties related to the realization of such
receivables, the Company recorded an allowance for all credits not backed by collateral. Such
allowance amounted to US$536 and US$527 as of December 31, 2006 and 2005, respectively.

    Domestic value-added sales tax are composed of credits generated by commercial
operations and by the acquisition of property, plant and equipment and can be offset with
taxes of the same nature.(2)
    
    PASEP and COFINS are social security contributions payable in respect of sales of
products and services and financial revenues.These contributions and the domestic value-added tax (ICMS) are not cumulative and
amounts paid related to these taxes in the acquisition of products and/or services can
be offset when these products and services are sold, which means a tax credit is
generated when the purchase is made and such credit is then offset upon sale to final
customer.The income tax and social contribution recoverable will be offset against future taxable
income.Petrobras plans to fully recover these taxes, and as such, no allowance has been
provided. F-35

    New Hydrocarbons Law of BoliviaThe new Bolivian Hydrocarbons Law 3,058 has been in force since May 19, 2005. This law revokes
the former Hydrocarbons Law 1,689 dated April 30, 1996.The new law establishes, among other matters, a higher tax burden for companies of the sector,
through royalties of 18% and a direct tax on hydrocarbons (IDH) of 32%, to be applied directly
on 100% of the production, on top of taxes in force by operation of Law No. 843. In addition,
the new legislation determines substitution of shared risk contracts for new contracts
observing the models established in the Law, and introduces changes in the oil products
distribution activity.On May 20, 2005, contracts were entered into for association among Yacimientos Petrolíferos
Fiscales Bolivianos  YPFB (Bolivian state-owned company) and fuel distribution companies to
extend the term of Distributors operations up until YPFB accumulates sufficient funds to
develop this segment all over the Bolivian territory. On June 30, 2006 the contracts term
expired through which the major distribution companies distributed hydrocarbons in Bolivia.
YPFB took over national distribution as from that date. The company Petrobras Bolívia
Distribución, which allowed the ownership of a major part of this business, is still operating
in the sector through the service stations it owns.As of May 1, 2006, Supreme Decree 28,701 was enacted in Bolivia, through which, the natural
hydrocarbon resources were nationalized. As a consequence, the companies that are currently
engaged in gas and petroleum production activities, will have to transfer the ownership of all
hydrocarbon production to Yacimientos Petrolíferos Fiscales Bolivianos (YPFB). A transition
period has also been established of 180 days as from the date the aforementioned decree is
enacted, in which companies that are currently operating should execute the new contracts
established by YPFB. Companies which have not executed these contracts by the end of this term
may be unable to continue operating in the country.

    New Hydrocarbons Law of Bolivia(Continued)The aforementioned Decree establishes that fields with a certified average natural gas
production of over 100 million cubic feet per day in 2005, as is the case with the San Alberto
and San Antonio fields where the Company operates, an additional amount will be paid to YPFB of
32% over of the production value, rising to a total of 82% of the Bolivian governments
interest. The Bolivian Ministry of Hydrocarbons and Energy shall determine on a case-by-case
basis via auditing the final share to be paid to the Companies in the contract to be executed.
Up to December 31, 2006 the Company had recorded a provision to pay the additional share to
YPFB of 32% on the hydrocarbon production, to an amount equal to US$99. The regulatory decrees
which among other matters shall establish the means for paying this share have not yet been
issued.Furthermore, according to this decree the State is nationalizing the shares required for YPFB
to control, with a minimum of 50% plus one share, Petrobras Bolívia Refinación S.A.  PBR, in
which Petrobras has an indirect interest of 100% (Petrobras International Braspetro B.V.  51%
and Petrobras Energia S.A.  49%). The equity interest will be transferred to YPFB when the
parties reach an agreement about the amount of economic compensation to be paid by YPFB to
Petrobras, besides the former compliance of some legal and statutory assumptions. The parties
have not yet commenced the assessment process.On October 28, 2006 Petrobras Bolívia and its partners executed operating contracts with YPFB
for San Alberto and San Antonio fields. These contracts establish that the revenues,
royalties, profit shares, IDH, shipment and compression will be absorbed by YPFB, and the cost
of production and investments made by the companies should be reimbursed as remuneration to the
owner. Any difference which may exist will be distributed between the Bolivian state company
and the companies, at percentages varying according to production and the investment recovery
factor. These contracts will come into force as from approval by the Bolivian National Congress
and their official registration.In a document attached to contracts entitled Investments made, Petrobras and its partners
state the investment amounts net of amortization, which will be reviewed taking into account
the results of the audits contracted by the Hydrocarbons Ministry, that are currently in
progress. To date, the Company is not aware of the result of these audits and the possible
effects on its investments.

    New Hydrocarbons Law of Bolivia(Continued)Supreme Decree 28,900-A issued October 28, 2006 established that the companies will continue
operating in Bolivia in accordance with Supreme Decree 28,701, including article 3, paragraph 1
which establishes the additional payment of 32% for the San Alberto and San Antonio fields
until the aforementioned contracts have been registered.On November 28, 2006 the National Congress approved the 44 oil contracts (exploration and
production), which include the contracts that Petrobras participates in/or operates, which
mainly include the San Alberto and San Antonio fields. On January 11, 2007 Laws were published
by which the Bolivian Legislative Branch approved these contracts, including those referring to
the San Alberto and San Antonio fields. To date the contracts have not been registered at a
registry office, despite the fact there is no justifiable reason for the delay. The contracts
will come into force after they have been effectively registered.PBR and PEBIS continue their normal operations under the control and management of the Company,
and hence their consolidated financial statements are still being included in the Companys
consolidated financial statements. The consolidated total assets balance of PEBIS as of
December 31, 2006 amounted to US$1,173.(c)
    
    Review of operating agreements in VenezuelaIn March of 2006, PESA, through its controlled and associated companies in Venezuela, entered
into Memoranda of Understanding (MOU) with PDVSA and Corporación Venezolana del Petróleo S.A.
(CVP) in order to finalize the migration of operational agreements to mixed-capital companies.
The MOUs establish that the interest of private partners in mixed-capital corporate companies
should be limited to 40%, while the Venezuelan government participates with the remaining 60%.
Thus, PESAs indirect interest in the fields of Oritupano Leona, La Concepción, Acema and Mata
Areas was defined as being of 22%, 36%, 34.5% and 34.5%, respectively.Pursuant to the terms of the MOU, CVP shall acknowledge dividable and transferable credits in
favor of the private companies with interest in the mixed-capital companies, which shall not be
subject to interest and may be used in payment of the acquisition bonus of new areas for
petroleum exploration and production activities or for a license to engage in gas exploration
and production.

    Review of operating agreements in Venezuela(Continued)During the transition period and until the mixed capital companies are in operation, the
consortias operations have been conducted and supported by Petrobras Energia Venezuela under
the supervision of an integrated operating committee, on which PDVSA representatives shall form
the majority.Due to the change in structure of shareholding interest in the mixed capital companies, from
April 1, 2006 the Company no longer consolidates the assets, liabilities and results of the
aforesaid operations in its consolidated statements, but presents them as equity investments in
non-consolidated companies and other investments, which increased the balance of such account
by US$878.(d)
    
    New Hydrocarbons Law in EcuadorIn April 2006, the Law which amended the Hydrocarbons Law (Ley de Hidrocarburos) was enacted in
Ecuador, which establishes the Government shall hold a minimum share of 50% in the
extraordinary revenues, generated by increases to the sale price of Ecuadorian oil (average
monthly effective FOB sale price) as compared to the monthly average oil sale price established
in the contract, stated in the currency of the month of settlement. In July, 2006 the
regulations of said Law were published which Ecuadortlc S.A., a subsidiary of PESA, and
Petroecuador interpreted differently. The application of this law is being disputed by
Ecuadortlc and Petroecuador.(e)
    
    SFAS No. 143  Accounting for asset retirement obligationsSince January 1, 2003, Petrobras adopted SFAS No. 143  Accounting for Asset Retirement
Obligations (SFAS 143). 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.Measurement of asset retirement obligations is based on currently enacted laws and regulations,
existing technology and site-specific costs. There are no assets legally restricted to be used
in the settlement of asset retirement obligations.

    ImpairmentFor the years ended December 31, 2006, 2005 and 2004, the Company recorded impairment charges
of US$21, US$156 and US$65, respectively. During 2006, the impairment charge was primarily
related to producing properties in Brazil and principle amounts were related to Petrobras
Córrego de Pedras on-shore field. During 2005, the impairment charge was primarily related to
investments in Venezuela (US$134), due to the tax and legal changes implemented by the Ministry
of Energy and Petroleum of Venezuela (MEP), previously mentioned. During 2004, the impairment
charge was related to producing properties in Brazil, principle amounts were related to the
Companys Ciobas off-shore field (US$30). The impairment expenses recorded in 2004 were
primarily due to capital expenditures made in 2004 to producing fields with only marginal
reserves.

    Includes US$878 related to investments in Venezuela, excluded from consolidation in
2006. (See Note 9 (c)). At December 31, 2006 and 2005, the Company had investments in companies with publicly traded shares: BRASKEM S.A., Petroquímica União S.A.  PQU and Companhia Petroquímica 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$548
and US$494 as of December 31, 2006 and 2005, respectively. These holding 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.The Company also has investments in companies for the purpose of developing, constructing,
operating, maintaining and exploring thermoelectric plants included in the federal governments
Priority Thermoelectric Energy Program, with equity interests of between 10% and 50%. The balance
of these investments as of December 31, 2006 and 2005 includes US$20 and US$179 respectively, and
are included as equity method investments due to the Companys ability to exercise significant
influence over such operations.The Companys investments in equity of non-consolidated companies generated equity earnings
(losses) in results of non-consolidated companies of US$28 for the year ended December 31, 2006
(2005  US$139; 2004  US$172).

acquisition of 12.41% of the shares (common and preferred) of Distribuidora de Gás Natural
Canalizado CEG-RIO, for US$17. With this acquisition, the shareholdings of GASPETRO in said
company were increased to 37.41%. The Company has accounted for its investment using the equity
method, retrospectively from the date of the initial investment. Due to the immateriality of
the involved amounts the Company has not retrospectively applied the equity method to the 2004
Financial Statements.The acquisition of the additional interest in CEG RIO was recorded using
the purchase method of accounting.(b)

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:

liens; limitations on transactions with affiliates; limitations on the disposition of assets;
limitation on consolidations, mergers, sales and/or conveyances; negative pledge restrictions;
change in ownership limitations; ranking; use of proceeds limitations; and required receivables
coverages. Petrobras management affirms that the Company is in compliance with the covenants
within debt agreements.At December 31, 2006 and 2005, 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 Federal Government guarantees TBGs Multilateral Credit Agency debt, which had an
outstanding balance of US$367 and US$402 at December 31, 2006 and 2005, 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, PIFCo, 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.

    Project FinancingsSince 1997, the Company has utilized project financings to provide capital for the continued
development of the Companys exploration and production and related projects.The special purpose entities associated with the project finance projects are consolidated based
on FIN 46(R) and the project financing obligation represents the debt of the consolidated SPEs
with the third-party lender.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, 2006 and 2005:

    Project Financings(Continued)Blade Securities LimitedThe Special Purpose Company (SPC) BLADE Securities Ltd (BLADE), was created by the Deutsche
Bank (DB), in order to support Petrobras in its transactions related to the acquisition of a 49%
interest held by ABB-EV in TERMOBAHIA power plant. (See Note 18 (h)). The financial structuring
involves two simultaneous operations: the acquisition of ABB-EVs rights and the sale of such
rights to a private institution, DB, until a strategic partner is introduced by Petrobras within
a maximum period of one year.Under the agreements, PIFCo paid to Blade US$1, and in return, Blade transferred to PIFCo the
right to any dividends to be received from TERMOBAHIA and the rights to the shares of TERMOBAHIA
either for PIFCo or a Petrobras subsidiary. Additionally, PIFCo paid to Blade US$38, and in
return, Blade transferred to PIFCo any amounts received from TERMOBAHIA related to the
subordinated loan recorded as notes receivable, which has an interest rate of 8% p.a. and an
expiry date of 2023, and the right to the loans receivable for PIFCo or a Petrobras subsidiary.
(See Note 18(h)).As a result of the trasaction series, Petrobras recognized a US$4 gain on debt extinguishment on
December 31, 2005, related to the fact it will no longer be paying 18.79% interest to a third
party lender. Due to immateriality, the Company has not applied step acquisition accounting to
the purchase of the interest in TERMOBAHIA.

    Pension plan  Fundação Petrobras de Seguridade Social  PETROSThe Fundação 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
post-retirement payments; and(iii)
    
    promote the well-being of its members, especially with respect to post-retirement
payments.
 The PETROS plan is a contributory defined-benefit pension plan introduced by Petrobras in July
of 1970, to supplement the social security pension benefits of employees of Petrobras and its
Brazilian subsidiaries and affiliated companies. 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 2006 year, benefits paid totaled US$713 (US$570 in 2005).The Companys liability related to future benefits to plan participants is calculated on an
annual basis by an independent actuary, based on the Projected Unit Credit method. The assets
that guarantee the pension plan are presented as a reduction to the net actuarial liabilities.The actuarial gains and losses generated by the differences between the values of the
obligation and assets determined based on projections and the actual figures, are respectively
included or excluded from the calculation of the net actuarial liability and recorded as
Postretirements benefit reserves adjustments net of tax  pension cost, in shareholders
equity. Actuarial gains and losses are amortized during the average remaining service period
of the active employees of approximately 10 years at December 31, 2006, 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 2006 and 2005
financial years, was 1.00 to 1.00. The Companys best estimate of contributions expected to be
paid in 2007 respective to the pension plan approximates US$194, with total pension benefit
payments in 2007 expected to be US$830.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, by an adjustment to the normal contributions.The PETROS Plan is closed to new employees of the Petrobras system joining from September 2002
and the Company contracted a group life insurance policy to cover employees commencing
employment with the Company subsequent to closure of the of the PETROS plan; this policy will
remain in effect until a new private pension plan is implemented.Plan assetsPlan assets are invested primarily in government securities, investment funds, equity
instruments and properties.

    Pension plan  Fundação Petrobras de Seguridade Social  PETROS(Continued)Plan assets(Continued)The Company uses 6.19% as the expected long-term rate of return over inflation on PETROS
assets. The PETROS portfolio of investments as of December 31, 2006 was comprised of 71%
securities, 44% of which were held-to-maturity government securities that earn interest at 6%
annually plus the IPCA (Consumer Price Index) variation and 27% of which were Investments Funds
that earn interest approximate to the CDI (Certificado de Depósito Interbancário, or Interbank
Deposit Certificate), which has been yielding more than 6% annually. Thus, the Company
considers a 6.19% long term interest rate appropriate to calculate the expected return on
assets, as such aligns with the composition of the PETROS asset portfolio.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 being recorded at fair value, for which a net present adjustment was required.
Thus, the percentage of assets allocated in this investment will remain the same over the short
term.New benefits planIn 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. However, the migration
of participants and beneficiaries of the previous plan (PETROS) to the new plan was suspended,
pursuant to a Federal Judicial ruling arising from an injunction filed by the employee union. A
court order in 2004 granted the injunction ruling against the new plan and invalidating any
changes to the PETROS plan premised upon intended migration to a new plan. This court decision
is under appeal.In 2003, the Company formed a task force with representatives of the National Union of Oil
Workers (FUP), unions and PETROS, among others, in order to evaluate alternatives to a new
model for the Companys supplementary pension plan, including analyses of negotiated
arrangements for the settlement of actuarial deficits.

    Pension plan  Fundação Petrobras de Seguridade Social  PETROS(Continued)New benefits plan(Continued)On April 19, 2006, the Company, aiming to achieve an agreement regarding its Supplementary
Pension Plan, presented to employee participants and retirees a proposal to bring equilibrium
to the actual PETROS Plan and the implementation of a new plan, denominated PETROS Plan 2.Execution of the proposal presented by the Companys Executive Board was subject to a number of
conditions, including the renegotiation of the PETROS Plan Regulations, in relation to the
means of readjusting the benefits and pensions, considering a significant rate of individual
accession of employees and dependants.The overall renegotiation target previously set by the Company had not been achieved. As a
result the proposal presented by Petrobras became null and void.On January 08, 2007, the Petrobras Board of Directors approved the reopening of the PETROS Plan
renegotiation process, in order to meet the claims of the trade unions, as most participants
were in favor of the renegotiation.The new target for the minimum accession number to the renegotiation was set at 2/3
(two-thirds) of the members and the final deadline for them to make their choice was February
28, 2007. The renegotiation target was met and the proposal submitted by the Company became
effective, and PETROS is calculating the amounts to be funded by the sponsors, that will reduce
the deficit of the PETROS Plan, as established by Brazilian pension law.On October 20, 2006, the Board of Directors of Petrobras approved the introduction of PETROS
Plan 2 for employees currently with no pension plan.The New Supplementary pension plan was formulated according to the Variable Contribution model.
In this model, the contributions are capitalized in individuals accounts, and the pension
benefits are established according to the account balances. This plan also includes risk
benefits with coverage for illness, incapacity and death, and a lifetime income.

coverage of the benefit to ensure it does not have a monetary value of under 30% of the average
contribution salary.On December 20, 2006 the Department for Coordinating and Controlling State Companies (DEST)
decided to approve the proposed PETROS Plan 2, which was also approved on January 05, 2007 by
the Ministry of Mines and Energy.On January 19, 2007, the PETROS Decision-making Board approved the PETROS Plan 2, which will be
referred for assessment and statement by the Supplementary Pensions Office  SPC, for the proper
final approval, whereupon it may be offered to the employees who are not presently covered by a
supplementary pension plan sponsored by the Company.Petrobras and the other sponsors will fully assume the contributions corresponding to the period
in which the new participants had no plan. This past service shall consider the period from the
date of admission to the date enrolment commenced in the PETROS Plan 2. The disbursements will
be conducted over the first months for contributions up to the total months the participant had
no plan, and shall cover the portion relating to the participants and sponsor. The maximum
estimated value of this actuarial commitment as of December 31, 2006 if the plan is approved by
SPC and accepted by all new employees was US$109.This New Plan also allows the Company to maintain the pension coverage it offers, mitigates the
risks presented by the defined benefit model adopted and considerably reduces the possibility of
future deficits. The impact of joining the new plan and its related benefit costs will be valued
according to the standards established in SFAS 87, 132 and 158 and will only be computed and
recognized in the accounts when the plan is implemented.

consists of granting, upon retirement, a one-month salary per years of service at the Company,
in conformity with a decreasing scale considering the years of effectiveness of the plan.Compensating FundThis is a defined benefit plan for all employees of Petrobras Energía who have joined the
Company prior to May 31, 1995, and have reached a certain number of years of service. The
employee benefit is based on the last computable salary and years of service of each employee
included in the fund.The plan is of a supplemental nature, that is to say the benefit to the employee is represented
by the amount determined under the provisions of this plan, after deducting benefits payable to
the employee under the contribution plan and the public retirement system, in order that the
aggregate benefit to each employee equals the one stipulated in this plan.

    PETROBRAS ENERGIA  PEPSA (including PESA)(Continued)Defined benefit plan(Continued)The plan calls for a contribution to a fund exclusively by Petrobras Energía and without any
contribution by the employees, provided that they should make contributions to the retirement
system for their whole salary. As provided in Petrobras Energías By-laws, the Company makes
contributions to the fund on the basis of a Board of Directors proposal to the Shareholders
Meeting up to 1.5% of net income for each year. The assets of the fund were contributed to a
trust. The goals with respect to asset investment are: (i) the preservation of capital in US
dollars, (ii) the maintenance of high levels of liquidity, and (iii) the attainment of the
highest yields possible on a 30-days basis. For this reason, the assets are invested mainly in
bonds, corporate bonds, mutual funds, and certificates of deposits. The Bank of New York is the
trustee and Watson Wyatt is the managing agent. Should there be an excess (duly certified by an
independent actuary) of the funds under the trust agreement to be used to settle the benefits
granted by the plan, Petrobras Energía will be entitled to make a choice and use it, in which
case it would have to notify the trustee thereof.(d)

132(R) (SFAS 158), which became effective for the Company on December 31, 2006. This
standard requires the Company to recognize the overfunded or underfunded status of each of its
defined benefit pension and other postretirement benefit plans as an asset or liability and to
reflect changes in the funded status through Accumulated other comprehensive income, as a
separate component of shareholders equity.

    Health care benefits  Assistência Multidisciplinar de Saúde (AMS)Petrobras and its Brazilian subsidiaries maintain a health care benefit plan (AMS), which
offers defined benefits and covers all employees (active and inactive) together with their
dependents. The plan is managed by the Company, with the employees contributing fixed amounts
to cover principal risks and a portion of the costs relating to other types of coverage in
accordance with participation tables defined by certain parameters including salary levels.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.

    Health care benefits  Assistência Multidisciplinar de Saúde (AMS)(Continued)Until 2006, the actuarial gains and losses generated by the differences between the values of
the obligation determined based on projections and the actual figures, were respectively
included or excluded when defining the net actuarial obligation.As of December 31, 2006, according to SFAS 158 (See Note 16(d)), the actuarial gains and losses
generated by the differences between the values of the obligation determined based on
projections and the actual figures, are respectively included or excluded from the calculation
of the actuarial obligation and recorded as Postretirements benefit reserves adjustments net
of tax- health care cost, as Accumulated Other Comprehensive Income,in shareholders equity.The gains and losses recorded as Accumulated Other Comprehensive Income are amortized over the
average remaining service period of the active employees.Upon adoption of SFAS 158, as of December 31, 2006 the liabilities related to health care
increased by US$1,495 and shareholders equity reduced by US$987, net of income taxes.On December 15, 2006, Petrobras implemented the Medicine Benefit, which provides special terms
on the acquisition of certain medicines by members of the AMS from participating drugstores,
located throughout Brazil.Following the introduction of this benefit, the unrecognized prior service cost estimated by
independent actuary, as of December 31, 2006 was US$86, and wil be amortized over the average
remaining service period of the active employees. The unrecognized prior service cost was
included in Accumulated Other Comprehensive Income and presented in Change in Benefit
Obligations, as Plan Amendments.For measurement purposes, a 10% 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 4.5% from 2007 to 2036.

    Employees Post-retirement Benefits and Other Benefits(Continued)
 (f)
    
    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.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.In 2004, Petrobras approved a change to a new mortality table of the actuarial assumptions of
the pension and healthcare plans in Brazil; this new mortality table reflects updated
assumptions and changes relative to the profile of employees, retirees and pensioners, based on
longevity, age of invalidity and invalid mortality tables.(g)
    
    Cash contributions and benefit paymentsIn 2006, the Company contributed US$187 to its pension plans. In 2007, the Company expects
contributions to be approximately US$194. Actual contribution amounts are dependent upon
investment returns, changes in pension obligations and other economic factors. Additional
funding may ultimately be required if investment returns are insufficient to offset increases
in plan obligations.

consisted of 2,536,673,672 common shares and 1,849,478,028 preferred shares, as retroactively
restated for stock split, mentioned below. 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.On May 13, 2005, Petrobras management approved the proposed share split and the related
amendment to article 4 of the Companys by-laws. These issues were discussed by the
shareholders at the Extraordinary General Meeting (EGM) held on June 15, 2005.The Extraordinary General Meeting held on July 22, 2005 decided to effect a split of each
Companys share into four, resulting in a free distribution of 3 (three) new shares of the same
type for each original share, based on the shareholding structure at August 31, 2005. At the
same date, an amendment to article 4 of the Companys by-laws to cause capital be divided into
4,386,151,700 shares, of which 2,536,673,672 are common shares and
1,849,478,028 are preferred shares, with no nominal value, was approved. This amendment to the Companys bylaws is
effective from September 1, 2005.

    Capital(Continued)The relation between the American Depository Receipt (ADS) and shares of each class was changed
from one to four shares for one ADS. All share and per share information in the accompanying
financial statements and notes has been adjusted to reflect the result of the share split.Current Brazilian law requires that the Federal Government retain ownership of 50% plus one
share of the Companys voting shares.Shareholders at the Extraordinary General Meeting held June 01, 2006 approved the incorporation
of shares in PETROQUISA by Petrobras, pursuant to the re-ratification of the Protocol of Merger
and Incorporation on the share incorporation transaction executed by the two companies. The
Board of Directors of the Company approved the issue of 886,670 preferred shares of the Company
in connection with the incorporation of shares in PETROQUISA by Petrobras.To implement the transaction, the exchange ratio for the shares to be used was based on the net
equity value of both companies at the base date of December 31,
2005, when 4.496 preferred shares issued by Petrobras were attributed to each batch of 1,000 common or preferred shares
issued by PETROQUISA.No Petrobras shareholders had stated their intention to exercise the right withdraw by the
legal deadline of July 07, 2006. Five PETROQUISAs shareholders with a total interest of
1,015,910 shares exercised the right to withdraw by the established deadline (by July 05, 2006)
and were reimbursed at the rate of R$153.47 (US$71) per batch of 1,000 shares, using funds
provided by PETROQUISA, on July 10, 2006. Petrobras then acquired the shares for the same
price, thereby transferring ownership.

Merchant)In February 2005, the arbitration proceedings began related to the dispute between Petrobras
and El Paso arising from the economic and financial imbalance deemed to exist relative to the

contract to be invalid and require re-negotiation as a result of changed economics. Related to
the disputes, Petrobras made a court ordered bank deposit related to unpaid contingency the
amounts, while awaiting final decision of the Arbitration proceedings.In March 2006 Petrobras and El Paso agreed to settle certain disputes involving the Macaé
Merchant Consortium. Under this settlement, the capital participation contract was terminated

    Commitments and ContingenciesPetrobras is subject to a number of commitments and contingencies arising in the normal course of

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 129,925 barrels per
day at respective current market prices.Petrobras provided guarantees to the ANP for the minimum exploration program defined in the
concession contracts for exploration areas, totaling US$2,425 (US$2,244 in 2005). Out of this
total, US$1,137(US$1,875 in 2005) represents a pledge on the oil to be extracted from previously
identified fields already in production, for areas in which the Company had already made
commercial discoveries or investments. For areas whose concessions were obtained by bidding from
the ANP, Petrobras has given bank guarantees totaling US$372 through December 31, 2006 (US$369 in

    Litigation(Continued)As of December 31, 2006 and 2005, in accordance with Brazilian law, the Company had paid US$816
and US$775, 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, 2006, this amount was included in the balance sheet as restricted
deposits for legal proceedings and guarantees.Plaintiff: Kallium Mineração S.A.On May 28, 1981, Kallium Mineração 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. Granted by the lower court, both parties
filed appeals, which were rejected. Petrobras is awaiting judgment of the Extraordinary Appeal
filed before the STF and the special appeal on December 18, 2003. A special appeal brought by
Kallium is also pending judgment. 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 possible.

should be obliged to reinstate the loss caused to the net worth of PETROQUISA, as a result of
the acts that approved the minimum sale price of its holding in the capital of privatized
companies. A decision was handed down on January 14, 1997 that considered Petrobras liable with
respect to PETROQUISA for losses and damages in an amount equivalent to US$3,406.In addition to this amount, Petrobras was required to pay the plaintiff 5% of the value of the
compensation as a premium (see art. 246, paragraph 2 of Law No. 6,404/76), in addition to
attorneys fees of approximately 20% of the same amount. 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. Against this decision, Porto Seguro filed another appeal (motion
to reverse or annul) with the State Court of Rio de Janeiro, and the Fourth Civil Court handed
down a unanimous decision on March 30, 2004 requiring Petrobras to indemnify PETROQUISA and
Porto Seguro the amounts of US$2,359 and US$590 respectively (the latter representing 5% in
premium and 20% in attorneys fees). Due to this result, Petrobras lodged appeal with high and
supreme courts, which was dismissed. In view of this decision, interlocutory appeal was filed
with High Court  STJ and Supreme Court  STF, which was converted into Special Appeal by STJ.

    Litigation(Continued)Plaintiff: PORTO SEGURO IMÓVEIS LTDA. (Continued)On May 6, 2005, the Superior Court of Justice (STJ) accepted the interlocutory appeal and
determined that the special appeal was to be proceeded with. Porto Seguro lodged an appeal
against the interlocutory decision, which was accepted by a majority vote on December 15, 2005,
and suspension of the special appeal filed by Petrobras was reinstated. The Company filed an
Interlocutory appeal against this latest decision, which was ruled on April 4, 2006 and which
unanimously overturned a decision which restored the impediment on the Special Appeal brought
by Petrobras, due to an impediment on one of the justices, determining another decision be
pronounced. Special Appeal by PORTO SEGURO rejected under a judgment delivered on September 05,
2006. In performance of the decision published on June 05, 2006, we are now awaiting assignment
of the agenda to re-examine the matter relating to the blocking of Petrobras Special Appeal.
If the award is not reversed, the indemnity estimated to PETROQUISA, including monetary
correction and interest, would be US$4,612. As Petrobras owns 100% of PETROQUISAs share
capital, a portion of the indemnity estimated at US$3,044, will not represent a disbursement
from Petrobras Group. In case of loss, Petrobras would have to pay US$201 to Porto Seguro and
US$922 to Lobo & Ideas by means of attorneys fees, however based on the opinion of its legal
advisers, the Company does not expect to obtain an unfavorable ruling in this case and
considers the risk of loss with respect to this lawsuit to be possible.

    Litigation(Continued)Plaintiff: The Fishermans Federation of the State of Rio de Janeiro (FEPERJ)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. At that time, Petrobras paid out extrajudicial
indemnification to everyone who proved to be fishermen when the accident occurred. According
to the records of the national fishermens register, only 3.339 could claim indemnification. 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. On February 02, 2007 a decision, partly accepting the expert report, was
published. That expert report was prepared to stablish the parameters for calculating the
award, which amounts to US$516 at that date. Petrobras will appeal before Rio de Janeiros
Supreme Court, because the parameters set in the decision differs from those already defined by
that same court. In accordance with the Companys expert assistant calculation, the recorded
amount of US$12 represents the award that will be set by the court at the end of the process.
Based on its legal counsels opinion, the Company  ́s Administration believes it is possible that
the Company will not prevail in this case.Plaintiff: São Paulo State tax authoritiesThe São Paulo tax authorities filed a tax suit against the Company, to demand payment of ICMS
on naphta-petrochemical operations carried out in the state for the period from September 1984
to February 1989. The suit was tried at all levels and the legal system eventually opposed the
argument defended by the Company, having understood that, in the specific case of these
operations, ICMS would apply.The case was settled and the Company entered into an agreement to pay US$122 plus interest,
totaling US$151, in 60 equal successive installments beginning April 2005.

    Litigation(Continued)Plaintiff: Distribution CompaniesThe 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 Goiás,
Tocantins, Bahia, Pará, Maranhão and in the Federal District.Of the total amount related to legal actions of approximately US$419, up to December 31, 2006
some US$38 (US$34 in 2005) had been withdrawn from the Companys accounts as a result of
judicial rulings of advance relief, which were annulled as a result of an appeal filed by the
Company.The Company, with the support of the state and federal authorities, has succeeded in stopping
the execution of other withdrawals, and is making all possible efforts to obtain reimbursement
of the amounts that were previously withdrawn from its accounts.(b)
    
    Notification from the INSS  joint liabilityThe Company received various tax assessments related to social security amounts payable as a
result of irregularities in presentation of documentation required by the INSS, to eliminate
its joint liability in contracting civil construction and other services, stipulated in
paragraphs 5 and 6 of article 219 and paragraphs 2 and 3 of article 220 of Decree No. 3,048/99.In order to guarantee the appeals filing and/or the obtainment from INSS of Debt Clearance
Certificate, US$55 from the amounts disbursed by the Company is recorded as sheet as restricted
deposits for legal proceedings and guarantees and may be recovered under the respective
proceedings in progress, which are related to 343 assessments amounting to US$178. Petrobras
legal department expects a possible defeat regarding these assessments, as it considers the
risk of future disbursement to be possible.Petrobras had disbursed during 2006 US$35 (US$85 in 2005), referring to administrative suits
filed by the INSS claiming the Companys joint liability.

    Tax assessmentsPlaintiff: Internal Revenue Service of Rio de Janeiro  Withholding Tax related to charter of
vesselsThe 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.

Petrobras filed a Voluntary Appeal, pending examination. To allow the appeal to proceed an
amount of US$20 was deposited and a bank guarantee to the amount of US$31 taken out, which
corresponds to 30% of the total amount. The voluntary appeal was accepted. However, the
assessment was upheld under the Special Appeal brought by the State Treasury. On October 02,
2006, the appeal deposit and bank guarantee were converted into income for the state. The
matter was then referred to the courts. The remaining amount deriving from the tax credit, duly
restated, relating to the final quarter of 2006 is around US$149, which corresponds to 70% of
the total claim. As the administrative proceedings have reached a conclusion and the amount
will be recorded as an overdue federal reliability, 20% will be added as attorneys fees. Based
on its legal counsels advice, the Company has assessed risk of loss to be possible.

    Derivative Instruments, Hedging and Risk Management Activities(Continued)The Company may use derivative and non-derivative instruments to implement its corporate risk
management strategy. However, by using derivative instruments, the Company exposes itself to
credit and market risk. Credit risk is the failure of a counterparty to perform under the terms
of the derivative contract. Market risk is the possible adverse effect on the value of an assets
or liability, including financial instruments that results from changes in interest rates,
currency exchange rates, or commodity prices. The Company addresses credit risk by restricting
the counterparties to such derivative financial instruments to major financial institutions.
Market risk is managed by the Companys executive officers. The Company does not hold or issue
financial instruments for trading purposes.In 2004, the Petrobras Executive Board organized a Risk Management Committee comprising executive
managers of all business areas and of several corporate areas for the purpose of ensuring
integrated management of risk exposures and formalization of the main guidelines adopted by the
Company to manage significant risks and uncertainties associated with its activities. The Risk
Management Committee was created with a view towards concentrating risk management information
and discussions and facilitating communications with the Board of Directors and the Executive
Board.
 (a)
    
    Foreign currency risk managementThe Companys foreign currency risk management strategy may involve the use of derivative
instruments to protect against foreign exchange rate volatility which may impact the value of
certain of the Companys obligations.During 2000, the Company entered into three zero cost foreign exchange rate collars to reduce
its exposure to variations between the U.S. Dollar and the Japanese Yen, and between the U.S.
Dollar and the EURO, relative to long-term debt denominated in foreign currencies with a face
value of approximately US$470. The Company did not apply hedge accounting for these
relationships. The collars were constructed by the simultaneous purchase of a call option and
sale of a put option with the same counterparty and with equal premiums.

    Derivative Instruments, Hedging and Risk Management Activities(Continued)
 (a)
    
    Foreign currency risk management(Continued)These collars establish a price ceiling and a price floor for the associated exchange rates. If
the exchange rate falls below the floor, the counterparties will pay the Company the difference
between the spot rate at the maturity date and the floor, calculated based on the notional
amount of the contracts. Conversely, if the exchange rate increases above the ceiling, the
Company will pay the counterparties the difference between the spot rate at the maturity date
and the ceiling, calculated based on the notional amount of the contracts on the notional
amount. The maturity dates of the derivatives contracts coincide with the maturity dates of
each of the notes.The Yen zero cost collar contracts were settled on September 8, 2003, with a cash payment of
US$68. One of the Euro zero cost collars was settled on December 31, 2004, with a cash receipt
of US$18.The call option component of the Companys zero cost foreign exchange collars at December 31,
2006 had a fair value of US$21 (US$12 at December 31, 2005) and the put option components a
fair value of zero at December 31, 2006 (US$(1) at December 31, 2005).(b)
    
    Commodity price risk managementPetroleum and oil productsThe Company is exposed to commodity price risks as a result of the fluctuation of crude oil and
oil product prices. The Companys commodity risk management activities are primarily
undertaking through the uses of future contracts traded on stock exchanges; and options and
swaps entered into with major financial institutions. The futures contracts provide economic
hedges for anticipated crude oil purchases and sales, generally forecasted to occur within a 30
to 360 day period, and reduce the Companys exposure to volatility of such prices.The Companys exposure from these contracts is limited to the difference between the contract
value and market value on the volumes contracted. Crude oil future contracts are
marked-to-market and related gains and losses are recognized in currently period earnings,
irrespective of when the physical crude sales occur. For the years ended December 31, 2006,
2005 and 2004, the Company entered into commodity derivative transactions for 26.42%, 26.79%
and 33.06%, respectively, of its total import and export trade volumes.

    Commodity price risk management(Continued)The open positions in the futures market, compared to spot market values, resulted in
recognized losses of US$2, US$1 and US$2 for the years ended December 31, 2006, 2005 and 2004,
respectively.A long-term position was opened in January 2001 via 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 of obtaining 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 put options 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 2006, 2005 and 2004 the Company realized no gain or loss.(c)
    
    Interest rate risk managementThe Companys interest rate risk is a function of the Companys long-term debt and to a lesser
extent, its short-term debt. The Companys foreign currency floating rate debt is principally
subject to fluctuations in LIBOR and the Companys floating rate debt denominated in Reais is
principally subject to fluctuations in the Brazilian long-term interest rate (TJLP) as fixed by
the National Monetary Counsel. The Company currently does not utilize derivative financial
instruments to manage its exposure to fluctuations in interest rates. However, the Company will
consider assessing the use of various types of derivatives to reduce its exposure to interest
rate fluctuations and may use such financial instruments in the future.

    Derivative Instruments, Hedging and Risk Management Activities(Continued)

    Risk Management activity at PEPSAPEPSA uses derivative instruments such as options, swaps and others, mainly to mitigate the
risk of changes in crude oil prices, interest rates and foreign exchange rates. Such derivative
instruments are designed to mitigate specific exposures, and when designated as accounting
hedges are assessed periodically to assure high correlation of the derivative instrument to the
hedged risk exposure identified and to ensure that the derivative is highly effective in
achieving offsetting changes in the cash flows of the hedged risk. PEPSA in the past designated
certain relationships as accounting hedges for its crude oil derivative instruments and its
interest rate swaps derivative instruments, but holds no such instruments at December 31, 2006;
nor are any implemented accounting hedges outstanding.As of December 31, 2006, PEPSA did not have commodity derivative transactions that qualify for
hedge accounting purposes in accordance with SFAS No. 133  Accounting for Derivative
Instruments and Hedging Activities (SFAS 133). PEPSA accounted for a loss of US$103 for the
year ended December 31, 2005 due to derivative financial instruments that did not qualify for
hedge accounting.At December 31, 2006, PEPSA had forward sales of US dollars in exchange for Argentine pesos.
During the current fiscal year, the Company recognized a US$2 gain. As of December 31, 2006 and
2005 the face value of effective contracts amounts to US$18 and US$52, respectively, at the
average exchange rate of 3.26 and 3 Argentine pesos per US dollar, respectively. Without
considering the above-mentioned operations, as of December 31, 2006, the Company did not have
any other positions in derivatives instruments.(e)
    
    Cash flow hedgeIn September, 2006 PIFCo entered into cross currency swap under which it swaps principal and
interest payments on Yen denominated bonds for U.S. dollar amounts. Under U.S. GAAP, foreign
currency cash flow hedges can only be designated as such when hedging the risk to the entitys
functional currency, and therefore, this cross currency swaps is qualified for hedge accounting
designation take into account that PIFCos functional currency is the US dollar, and the
assessment of hedge effectiveness indicates that the change in fair value of the designated
hedging instrument is highly effective.

    Cash flow hedge(Continued)The hedged item is ¥ 35 billion bond, ten-year maturity, carrying a semi-annual coupon of 2.15%
p.a. The hedge instrument is a cross currency swap, ten year maturity, under which US dollars is
paid and Japanese Yen is received mirroring the Yen bond conditions. The effectiveness test was
made at the inception at the hedge based on the hypothetical derivative method. The
effectiveness test will be made on an ongoing basis on a quarterly basis.The transaction gain or loss arising from the remeasurement of Yen denominated bonds is offset
by the reclassification relating to the remeasurement of the hedged item at spot rates from
other comprehensive income to earnings. The cross currency swap at December 31, 2006 had a fair
value of (US$9) due to the devaluation of the Japanese Yen when compared to US dollar since the
inception of the instrument.

    Natural Gas Derivative ContractIn connection with the long-term contract to buy gas (The Gas Supply Agreement or GSA) to
supply thermoelectric plants and for other uses in Brazil, the Company entered into a contract,
with the company Empresa Petrolera ANDINA, a gas producer in Bolivia, that constituted a
derivative financial instrument under SFAS 133. This contract, the Natural Gas Price Volatility
Reduction Contract (the PVRC), was executed with the purpose of reducing the effects of price
volatility under the GSA.The terms of the PVRC provided for a price collar for the period from 2005 to 2019, with the
Company receiving cash payments when the calculated price is above the established ceiling, and
the Company making cash payments when the price is below the established floor, with no cash
payments being made when the price is between the ceiling and the floor.As of December 31, 2005, the Company recorded an asset based on the fair value of the derivative
in the amount of US$547 and a liability of US$144, which was deemed a deferred purchase
incentive.

    Natural Gas Derivative Contract(Continued)Due to the new Hydrocarbons Law of Bolivia (see Note 9(b)), the other party to the PVRC contested
the contract, alleging among others, force majeure and excessive onus. On August 12, 2006, the
parties agreed to cancel the PVRC. As a result, on August 14, 2006 the Company received US$41 and
wrote-off accounts receivable related to the PVRC amounting to US$77.The Company adjusted the fair value asset and liabilities related to the PVRC by recording a
financial expense of US$328 during the first quarter of 2006 as a result of the tax increases in
Bolivia. In the second quarter of 2006, the Company wrote-off the remaining fair value asset of
US$94 as a consequence of the cancellation of contract.

    Financial InstrumentsIn the normal course of its business activities, the Company acquires various types of financial
instruments.
 (a)
    
    Concentrations of credit riskSubstantial portions of the Companys assets including financial instruments are located in
Brazil while substantially all of the Companys revenues and net income are generated in
Brazil. The Companys financial instruments that are exposed to concentrations of credit risk
consist primarily of its cash and cash equivalents, government securities, the Petroleum and
Alcohol account, trade receivables and futures contracts.The Company takes several measures to reduce its credit risk to acceptable levels. All cash and
cash equivalents in Brazil are maintained with major banks. Time deposits in U.S. dollars are
placed with creditworthy institutions in the United States. Additionally, all of the Companys
available-for-sale securities and derivative contracts are either exchange traded or maintained
with creditworthy financial institutions. The Company monitors its credit risk associated with
trade receivables by routinely assessing the creditworthiness of its customers. At December 31,
2006 and December 31, 2005, the Companys trade receivables were primarily maintained with
large distributors.

    In 2005 revenues from commercialization of oil to third parties are being classified in
accordance with the points of sale, which could be Exploration & Production or Supply
segments. Until 2004, revenues from commercialization of oil were completely allocated to
Exploration & Production. This classification generated no significant impact on the
results reported for these segments and segments information has not been restated as it is
impractical to gather and collect data for prior periods as to point of sale.(2)
    
    In order to align the financial statements of each business segment with the best
practices of companies in the Oil & Gas sector and to improve the understanding of
Petrobras management, the Company, since the first quarter of 2006, switched to allocating
all financial results and items of financial nature to the corporate level. F-123

    In order to align the financial statements of each business segment with the best
practices of companies in the Oil & Gas sector and to improve the understanding of
Petrobras management, the Company, since the first quarter of 2006, switched to allocating
all financial results and items of financial nature to the corporate level.

    Accounting for Suspended Exploratory Wells(Continued)Costs the Company has incurred to drill exploratory wells that find commercial quantities of
oil and gas are carried as assets on its balance sheet under the classification Property,
plant and equipment as unproved oil and gas properties. Each year, the Company writes off the
costs of these wells that have not found sufficient proved reserves to justify completion as a
producing well, unless (1) the well is in an area requiring major capital expenditure before
production can begin and (2) additional exploratory drilling is under way or firmly planned to
determine whether the capital expenditure is justified.As of December 31, 2006, the total amount of unproved oil and gas properties was US$2,054, and
of that amount US$321 (US$195 of which related to projects in Brazil) represented costs that
had been capitalized for more than one year, which generally are a result of (1) extended
exploratory activities associated with offshore production and (2) the transitory effects of
deregulation in the Brazilian oil and gas industry, as described below.In 1998, the Companys government-granted monopoly ended and the Company signed concession
contracts with the Agência Nacional de Petróleo (National Petroleum Agency, or ANP) for all of
the areas the Company had been exploring and developing prior to 1998, which consisted of 397
concession blocks. Since 1998, the ANP has conducted competitive bidding rounds for
exploration rights, which has allowed the Company to acquire additional concession blocks.
After a concession block is found to contain a successful exploratory well, we must submit an
Evaluation Plan to the ANP for approval. This Evaluation Plan details the drilling plans for
additional exploratory wells. An Evaluation Plan is only submitted for those concession areas
where technical and economic feasibility analyses on existing exploration wells evidence
justification for completion of such wells. Until the ANP approves the Evaluation Plan, the
drilling of additional exploratory wells cannot commence. If companies do not find commercial
quantities of oil and gas within a specific time period, generally 4-6 years depending on the
characteristics of the exploration area, then the concession block must be relinquished and
returned to the ANP. Because the Company was required to assess a large volume of concession
blocks in a limited time frame even when an exploratory well has found sufficient reserves to
justify completion and additional wells are firmly planned, finite resources

    Global NotesOn January 4, 2007, PIFCo, a wholly owned subsidiary of Petrobras, announced an offer for
the exchange of securities (Exchange Offering) totaling up US$500 (face value) for the
five series of notes.The objective of the Exchange was offer to the investors the opportunity to substitute the
five old notes listed below, with PIFCos new benchmark issued on October 06, 2006, with a
coupon of 6.125% per annum and maturity in 2016.The settlement of the Exchange Offering occurred on February 7, 2007 and as a result, PIFCo
received and accepted a tender amount of US$399 (face value of the Notes). All the notes
received were cancelled in the same day and as a consequence, PIFCo issued US$399 of Global
Notes due 2016 that bear interest at the rate of 6.125% per annun, payable semi-annually.
The new Notes constitute a single, fungible series with the US$500 Global Notes due 2016
and issued on October 06, 2006, amounting to US$899 in securities issued with maturity in
2016. PIFCo also paid to the investors a cash amount equivalent to US$56 as a result of the
Exchange. The table below presents the result of the Exchange.

    Leasing of the Araucária Gas Thermoelectric Power StationPetrobras announced on January 3, 2007 that it had executed two service provision and
leasing contracts with UEG Araucária and COPEL. The first contract refers to the leasing
of the Araucária Gas Thermoelectric Power Station executed by Petrobras and UEG, in force
until December 31, 2007 which may be extended for a period of up to 12 months. The second
contract involves the provision of maintenance and operating services regarding the UEG
Araucária, executed by Petrobras and COPEL Geração, in force until December 31, 2008 or
the end of the leasing agreement, whichever occurs first.Under the two contracts, a fixed monthly payment will be due of US$8.89 per MWh multiplied
by the reference voltage (428,35 MW) plus a variable monthly payment of US$15.54 per MWh,
on the effective energy generated. These proceeds are used to cover all costs and taxes
incurred by UEG.Executing these contracts will enable better allocation of the gas produced to meet the
fundamental commitments referring to the energy sold by the Company.(c)
    
    Repactuation of PETROS PlanDuring 2006 Petrobras presented to employee participants and retirees a proposal to bring
equilibrium to the actual PETROS Plan. On February 28, 2007 the target for the minimum
accession number to the renegotiation set at 2/3 (two-thirds) of the members and was met
(see Note 16 (b)).The renegotiation process consists of changing the plans regulation, particularly the
articles related to how the benefits are readjusted, disentailing the readjustment of the
benefits paid to retirees and pensioners from wage increases granted to active employees
and INSS retirees. Petros Plan benefits, disentailed from the active employees wage and
INSS retirement and pension plan readjustments, will be adjusted based on the IPCA (cost
of living index).

    Repactuation of PETROS Plan(Continued)The financial incentive to be granted to the participants, whether employees or retirees,
as negotiated by the labor union representatives as a counterpart for the Plans
repactuation, amounted to US$425 and was paid on March 2007.The proposals approval also opens the way to reach agreements with Labor Union
Representations in order to liquidate and extinguish legal suits, particularly the Public
Civil Suit regarding Petrobras Systems complementary retirement issues. The demands that
refer to the items to be removed from the lawsuits will be attended to through the
calculation of their actuarial value and paid for by Petrobras, in 20 years, respecting
the Plans liquidity conditions.(d)
    
    Ipiranga Group AcquisitionOn March 19, 2007, Ultrapar Participações S.A. (Ultrapar) has celebrated, with the
acknowledgement of Petróleo Brasileiro S.A. (Petrobras) and Braskem S.A.(Braskem) a
contract with the controlling shareholders of Refinaria de Petróleo Ipiranga S.A,
Distribuidora de Produtos de Petróleo Ipiranga S.A. and Companhia Brasileira de Petróleo
Ipiranga for the acquisition of their total interest in those companies, including
petrochemical and distribution assets.After the completion of the acquisition, the businesses of the Ipiranga Group will be
managed by Ultrapar, Petrobras and Braskem. Ultrapar will hold 100% interest of the oil
products and lubricant distribution businesses located in the South and Southeast regions
of Brazil, Petrobras will hold 100% interest of the oil products and lubricant
distribution businesses located in the North, Northeast and Central West regions of
Brazil. Petrobras and Braskem will hold the petrochemical assets in the proportion of 40%
and 60% respectively. The assets related to refining operations will be equally shared
between Petrobras, Ultrapar and Braskem.

    Results of operations for oil and gas producing activitiesThe Companys results of operations from oil and gas producing activities for the years ending
December 31, 2006, 2005 and 2004 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.

    Reserve quantities informationThe Companys estimated net proved oil and gas reserves and changes thereto for the years 2006,
2005 and 2004 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.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.

    Reserve quantities information(Continued)The decrease in reserves is related to revisions of previous estimates due to Bolivia
and Venezuela new nationalization measures during 2006. The new regulation in Venezuela
reduced our reserves as PDVSA became the main controller of the companies created to
operate the fields with private companies. In Bolivia, due to new government regulations,
occurred a decrease in the reserves. In Nigeria, the consortium in charge of Akpo field was
constituted by Total, Petrobras and a Nigerian private company called SAPETRO. The
agreement underwritten by these companies established that TOTAL and Petrobras carried the
investment cost of the third part and it would be compensated in the future with SAPETROs
production/reserves.Along 2006, SAPETRO sold its participation to a Chinese oil company and, as part of this
agreement, Petrobras and TOTAL were reimbursed for their past carrying investments(v)
    
    Standardized measure of discounted future net cash flows relating to proved oil and gas
quantities and changes thereinThe 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
involves uncertainty 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.

    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.

PFL also purchased bunker fuel from PETROBRAS. Certain sales were through subsidiaries of
PETROBRAS.PETROBRAS EUROPE LIMITEDPETROBRAS EUROPE LIMITED (PEL), based in the United Kingdom, consolidates PETROBRAS European
trade and finance activities. These activities consist of advising on and negotiating the terms
and conditions for crude oil and oil products supplied to PIFCo and PETROBRAS, as well as

    Unearned incomeUnearned income represents the unearned premium charged by the Company to PETROBRAS and
ALBERTO PASQUALINI  REFAP S.A. (REFAP) to compensate for its financing costs. The premium
is billed to PETROBRAS and REFAP at the same time the related product is sold, and is
deferred and recognized into earnings as a component of financial income on a
straight-line basis over the collection period, which ranges from 120 to 330 days, in
order to match the premium billed with the Companys financial expense.(i)
    
    Revenues, costs, income and expensesFor all third party and related party transactions, revenues are recognized in accordance
with the U.S. SECs Staff Accounting Bulletion 104  Revenue Recognition. Crude oil and
oil products revenues are recognized on an accrual basis when persuasive evidence of an
arrangement exists in the form of a valid contract, delivery has occurred or title has
transferred, the price is fixed or determinable and collectability is reasonably assured.
Costs are recognized when incurred. Income and expenses include financial interest and
charges, at official rates or indexes, relating to current and non-current assets and
liabilities and, when applicable, the effects arising from the adjustment of assets to
market or realizable value.The principle commercial transactions of the Company consist of:Imports  the company buys from suppliers outside Brazil (mainly from third-parties) and
sells to PETROBRAS and its Brazilian subsidiaries.Exports  the Company buys from PETROBRAS and sells to customers outside Brazil.Off-shore  the Company buys and sells mainly outside of Brazil, in transactions with
third-parties and related parties.

    Financial instrumentsAll of the Companys derivative instruments are recorded in the consolidated balance sheet
at their fair value. For exchange-traded contracts, fair value is based on quoted market
prices. For non-exchange traded contracts, fair value is based on dealer quotes, pricing
models or quoted prices for instruments with similar characteristics. The transaction
price is used as the initial fair value of the contracts.PIFCo designates at inception whether the derivative contact will be considered hedging or
non-hedging for SFAS 133 accounting purposes. Non-hedging derivatives that are considered
economic hedges, but not designated in a hedging relationship for accounting purposes, are
recorded as other current assets or liabilities, with changes in fair value recorded as
financial income or financial expense.For SFAS 133 hedges, PIFCo formally documents at inception all relationships; identifying
the hedging instrument and hedged item, as well as its risk management objectives and
strategies for undertaking the hedge. The Company assesses at the hedges inception and
for each reporting date thereafter whether the derivative used in the hedging transaction
is expected to be and has been highly effective.As of December 31, 2006, PIFCo has designated one hedging relationship for accounting
purposes as a cash flow hedge in order to manage foreign currency exchange rate risk.
Changes in the fair value of the derivative hedging instrument are recorded in Accumulated
OCI. Any hedge ineffectiveness, as well as the excluded component of the derivative from
the effectiveness assessments, are recorded directly in earnings (note 8(iv)).PIFCo had written put options in the past that allows the holder of the options to sell a
floating number of heavy fuel oil volumes at a minimum price of US$14/barrel. Such option
had served as an economic hedge on related future sales of receivables under the
structured finance export prepayment program; the intent of which was to ensure that
physical barrels delivered under the project finance agreement generate sufficient cash
proceeds to repay related financial obligations. Given the low strike price relative to
the market the fair value of these options is immaterial at December 31, 2006.

    Income taxesThe Company accounts for income taxes using an asset and liability approach, which
requires the recognition of taxes payable or refundable for the current year and deferred
tax liabilities and assets representing the future tax consequences of events that have
been recognized in the Companys financial statements or tax return. The measurement of
current and deferred tax liabilities and assets is based on the provisions of the tax laws
in the countries in which the Company and its subsidiaries operate (the United Kingdom,
Bermuda, Singapore and the Cayman Islands in 2006 and the United Kingdom, Bermuda and the
Cayman Islands in 2005 and 2004). Deferred tax assets are reduced by the amount of any tax
benefits when, based on the available evidence, such benefit may not be realized. The
Cayman Islands and Bermuda have no corporate tax requirements, therefore the Company has
no tax provision from these locations and no significant operations in the United Kingdom
or Singapore.

    Changes in fair value related to the securities classified as available for sale in
accordance with FAS 115 are diminimus and were included in the Statement of Operations as
financial income or expense. Marketable securities are comprised of amounts the Company has invested in the exclusive
portfolio of an investment fund, operated exclusively for PIFCo, which holds certain PIFCo and
PETROBRAS group securities among its other investments which are classified as held to
maturity, trading or available for sale under SFAS 115 based on managements intent. The
trading securities are presented as current assets, as they are expected to be used in the near
term for cash funding requirements; available for sale securities are presented as other
long-term assets, as they are not expected to be sold or liquidated in the next twelve months.At December 31, 2005, PIFCo had amounts invested in an exclusive portfolio of an investment
fund that held its own debt securities in the total amount of US$ 215,638. This amount was
recognized as an extinguishment of debt and offset against the balance of financing classified
under current and non-current liabilities. There were no repurchased securities of PIFCo debt
at December 31, 2006.

 Commercial operations between PIFCo and its subsidiaries and affiliated companies are carried out
under normal market conditions and at commercial prices, except for the sales of oil and oil
products to PETROBRAS, which have an extended settlement period consistent with PIFCos formation
as a financing entity, and include finance charges accrued during the extended payment period.Certain affiliates of PIFCo and PFL, which are subsidiaries of Petrobras, serve as agents in
connection with export sales to certain customers under the export prepayment program. Those
transactions have been classified as related party transactions for purposes of these financial
statements.The transactions were realized to support the financial and operational strategy of the Companys
Parent Company, PETRÓLEO BRASILEIRO S.A.  PETROBRAS.
 (i)
    
    Accounts receivable from related parties relate principally to crude oil sales made by the
Company to PETROBRAS, with extended payment terms of up to 330 days. Extended payment terms for
accounts receivable from related parties were up to 270 days in 2004.(ii)
    
    Long-Term Liabilities  Notes payable relate to loans executed between the Company and
PETROBRAS due in 2021, with annual interest rates ranging from 8.3% to 8.6%.(iii)
    
    Purchases from related parties are presented in the cost of sales section of the
statement of operations.(iv)
    
    On December 28, 2005, in order to lend support to Petrobras in its transactions related
to the Termobahia power plant, PIFCo entered into a series of agreements with Blade
Securities Ltd , a special purpose company holding 49% of the equity shares of Termobahia
(consolidated by Petrobras). Under the agreements, PIFCo paid to Blade US$ 1,453, and in
return, Blade transfers to PIFCo the right of any dividends to be received from Termobahia
and the rights to the shares of Termobahia either for PIFCo or a Petrobras subsidiary.
Additionally, PIFCo paid to Blade US$ 38,185, and in return, Blade transfers to PIFCo any
amounts received from Termobahia related to the subordinated loan recorded as notes
receivable, which has an interest rate of 8% p.a. and an expiry date of 2023, and the right
to the loans receivable for PIFCo or a Petrobras subsidiary. Petrobras has the intention of
finding a strategic partner within one year time frame to purchase the Termobahia equity
interest and related loan.

    On December 31, 2005, the Company had amounts invested in an exclusive portfolio of
an investment fund that held its own debt securities in the total amount of US$ 215,638.
These securities were considered to be extinguished, and thus the related amounts,
together with applicable interest, which comprise the current portion at the respective
date, have been removed from the presentation of marketable securities and short and
long-term debt. Gain and losses on extinguishment are recognized as incurred. Subsequent
reissuances of notes at amounts greater or lesser than par are recorded as premiums or
discounts and are amortized over the life of the notes. As of December 31, 2006 and
December 31, 2005, the outstanding balance of net premiums on reissuances amounted to
US$ 10,273 and US$ 18,464, respectively. PIFCo incurred in expenses in the total amount of
US$ 11,738 on extinguishment of debt during 2005 and US$ 160,048 during 2006.(iii)
    
    On July 24, 2006, PIFCo concluded its debt repurchase offer (Tender) announced on
July 18, 2006. The amount of notes tendered for five series of notes listed below was US$
888,260. Including the notes previously repurchased by Petrobras and its affiliates, also
included in the tender, the total value reached US$ 1,215,661. The purpose of this
initiative was to reduce total debt outstanding and simplify the debt profile, thus
benefiting from the Companys current strong cash generation. The transaction was settled
on July 27, 2006 and all the notes tendered were canceled from this date. Upon conclusion
of the debt repurchase offer (Tender), PIFCo incurred in expenses in the total amount of
US$ 160,048.

    On September 27, 2006, the Company concluded a private placement of securities in the
Japanese capital market (Shibosai) for a total of ¥ 35 billion (US$ 297,780) due
September 2016. The issue was a private placement in Japanese market with a partial
guarantee of Japan Bank for International Cooperation (JBIC) and bears interest at the
rate of 2.15% per annum, payable semiannually. PIFCo used the proceeds principally to
finance PNBV, an affiliate, for construction of lines interconnecting the P-51, P-52 and
P-53 production platforms to the PRA-1 autonomous repumping unit.In the same date, PIFCo entered into cross currency swaps under which it swaps the
principal and interest payments on Yen denominated funding into U.S. dollars; and
designated the hedging relationship as a qualifying cash flow hedge under SFAS 133. The
hedged item is a ¥ 35 billion 10 year issued bond, with a semi-annual coupon of 2.15% p.a.
The hedging instrument is a series of cross currency swaps, whose notional amounts,
underlyings and maturities match the terms of the funding; in which U.S. dollars are paid
and Japanese Yen are received.The transaction gain or loss arising from the remeasurement of Yen denominated bonds is
offset by the reclassification relating to the remeasurement of the hedged item at spot
rates from other comprehensive income to earnings. The cross currency swap at December 31,
2006 had a fair value of US$ 8,754 due to the devaluation of the Japanese Yen when
compared to U.S. dollar since the inception of the instrument. No amounts were recognized
in earnings during the year as hedge ineffectivenesses. Accumulated other comprehensive
income were reclassified at the reporting date in order to offset the foreign currency
exchange gain or losses on the hedged item.(v)
    
    On September 1, 2005, PFL prepaid the floating rate Senior Trust Certificates
(Series A2 and C) in accordance with the applicable provisions of the governing
agreements. In order to facilitate this advance payment, Petrobras prepaid to PFL an
amount of US$ 330,290 related to the export prepayment program.On March 1, 2006, PFL prepaid the fixed rate Senior Trust Certificates (Series A1 and B) in
accordance with the applicable provisions of the governing agreements in the amount of US$ 333,860.

 Certificates (Series A1 and B) PFL paid premium in the total amount of US$ 13,650.On May 26, 2006, PFL has successfully completed a solicitation of consents from holders
of the Series 2003-A 6.436% Senior Trust Certificates due 2015 issued by PF Export
Receivables Master Trust. The amendments sought to eliminate exports of bunker fuel from
the transaction so that the securities have been collateralized only by receivables from
sales of fuel oil exported by Petrobras and to reduce the minimum average daily gross
exports of fuel oil for any rolling twelve-month period. PFL also obtained the consent
from the holders of Series 2003-B 3.748% due 2013. The amendments became effective on
June 1, 2006.As a result of these amendments, the premium rate of the guarantee of the Series 2003-B
was reduced from 1.8% to 1.1%.(vi)
    
    In May 2004, PFL and the PF Export Trust (the Trust) executed an amendment to the
Trust Agreement allowing the Junior Trust Certificates to be set-off against the related
Notes, rather than paid in full, after fulfillment of all obligations pursuant to the
Senior Trust Certificates. The effect of this amendment is that amounts related to the
Junior Trust Certificates have been presented net, rather than gross in these
consolidated financial statements, and thus US$ 150,000 has been reduced from the long
term debt financing respective to sales of right to future receivables.(vii)
    
    On October 06, 2006, the Company issued Global Notes of US$ 500,000 due October,
2016. The notes bear interest at the rate of 6.125% per annum, payable semiannually. The
Company used the proceeds from this issuance principally to repay trade-related debt and
inter-company loans.
