 of the year, including abandonment costs, based on cost indications at the end of the year, assuming as a premise
the continuity of economic conditions at the end of the year. The estimated future income tax is calculated using the official rates
in force at the end of the year. In Brazil, together with income tax, future social contributions are included. The amounts presented
as future income tax expenses include permitted deductions, to which official rates apply. Net discounted future cash flows are calculated
using discount factors of 10%, applied mid-year. This discounted future cash flow requires estimates of when future expenditures will
be incurred and when reserves will be extracted, year by year.

The valuation prescribed under Codification Topic 932 –
Extractive Activities – Oil and Gas 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.

Information relating to the standardized measurement of discounted
future net cash flows is originally presented in US dollars on SEC Form 20-F and was converted into reais for presentation in these financial
statements. Therefore, in order to maintain consistency with the criteria used to measure estimates of future cash inflows, as previously
described, the exchange rate used for conversion for each period is derived from the average exchange rate of the US dollar during the
12-month period prior to the closing date, determined as an unweighted arithmetic average of the exchange rate on the first day of each
month within that period. The exchange rate variations arising from this conversion are shown as accumulated conversion adjustments in
the flow movement tables, as follows:
