| b) | Derivative financial instruments    
 not designated for hedge accounting |

In September 2019, Petrobras contracted a cross-currency
swap aiming to protect against exposure arising from the 7 issuance of debentures, for IPCA x CDI operations, maturing in
September 2029 and September 2034, and for CDI x U.S. Dollar operations, maturing in September 2029.

The methodology used to calculate the fair value
of this swap operation consists of calculating the future value of the operations, using rates agreed in each contract and the projections
of the interest rate curves, IPCA coupon and foreign exchange coupon, discounting to present value using the risk-free rate. Curves are
obtained from Bloomberg based on forward contracts traded in stock exchanges.

The mark-to-market is adjusted to the credit risk
of the financial institutions, which is not relevant in terms of financial volume, since the Company makes contracts with highly rated
banks.

Changes in interest rate forward curves (CDI interest
rate) may affect the Company's results, due to the market value of these swap contracts. In preparing a sensitivity analysis for these
curves, a parallel shock was estimated based on the average maturity of these swap contracts, in the scope of the Company’s Risk
Management Policy, which resulted in a 527 basis point effect on the estimated interest rate. The effect of this sensitivity analysis,
keeping all other variables constant, is shown in the following table:

| Schedule of sensitivity analysis, keeping all other variables remaining constant |     |                              |
| Financial Instruments                                                            |     | Reasonably possible scenario |
| Swap CDI x USD                                                                   |     |                           17 |

| c) | Sensitivity analysis for foreign            
 exchange rate risk on financial instruments |

The sensitivity analysis only covers the exchange
rate variation and maintains all other variables constant. The probable scenario is referenced on external sources like Focus bulletin
and Thomson Reuters, making use of the exchange rate forecast for the end of the following year, as follows:

| · | U.S. dollar x real - a 5.45% depreciation of the 
 real;                                            |

| · | euro x U.S. dollar - a 1.54 % appreciation of the 
 euro;                                             |

| · | pound sterling x U.S. dollar - a 0.56 % appreciation 
 of the
