| 4.8. | Sources of estimation uncertainty                                            
 related to cash flow hedge accounting involving the Company’s future exports |

The Company determines its “highly probable
future exports” based on its current Business Plan and on short-term estimates on a monthly basis. The highly probable future exports
are determined by a percentage of projected export revenues.

The estimate of the amount of highly probable future
exports considers future uncertainty regarding the Brent oil prices, oil production and demand for products in a model which optimizes
the Company's operations and investments, in addition to considering the historical profile of exported volume in relation to total oil
production.

As described in note 33.4.1, foreign exchange gains
and losses relating to the effective portion of hedging instruments are recognized in other comprehensive income and reclassified to the
statement of income within finance income (expense) in the periods when the hedged item affects the statement of income. However, if future
exports for which foreign exchange gains and losses hedging relationship has been designated is no longer expected to occur, any related
cumulative foreign exchange gains or losses that have been recognized in other comprehensive income from the date the hedging relationship
was designated to the date the Company revoked the designation is immediately recycled from other comprehensive income to the statement
of income.

For the long-term, future exports forecasts are
reviewed whenever the Company reviews its Strategic Plan assumptions, while for the short-term future exports are reviewed monthly. The
approach for determining highly probable future exports is reviewed annually, at least.

See note 33.4.1 for more detailed information about
cash flow hedge accounting and a sensitivity analysis of the cash flow hedge involving future exports.

| 4.9. | Sources of estimation uncertainty 
 related to income taxes           |

Income taxes rules and regulations may be interpreted
differently by tax authorities, and situations may arise in which these interpretations differ from the Company's understanding.

Uncertainties over income taxes treatments represent
the risks that the tax authority does not accept a certain tax treatment applied by the Company, mainly related to different interpretations
of deductions and additions to the income taxes (Imposto de Renda sobre Pessoa Jurídica - IRPJ and Contribuição Social sobre Lucro Líquido – CSLL) calculation basis. The Company evaluates each uncertain tax treatment separately or
