 Santos Basin. There were no relevant changes related to the variation in the
oil price.

The evolution of proved reserves
is shown in the graph below.

Apparent differences in sums are
due to rounding. Does not consider: (a) natural gas liquids, since the reserve is estimated at a reference point prior
to gas processing, except in the United States and Argentina; (b) volumes of injected gas; (c) production from extended well tests in
exploration blocks; and (d) production in Bolivia, since the Bolivian Constitution does not allow the registration of reserves by the
company.

The ratio between proved reserves
and production (R/P ratio) is 13.2 years.

DeGolyer and MacNaughton (D&M).
