 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 594 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:

| Financial Instruments |     | Reasonably possible scenario |
| SWAP CDI x USD        |     |                          -67 |

| 50 |

| This interim financial information should be read together with the Company’s audited annual financial statements(Expressed in millions of reais, unless otherwise indicated) |

| c) | Sensitivity analysis for foreign exchange 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 2.75% depreciation of the real; |

| · | Euro x U.S. dollar - a 1.9 % depreciation of the euro; |

| · | Pound sterling x U.S. dollar - a 1.4 % depreciation of the pound sterling. |

The reasonably possible scenario has the same references and
considers the risk of a 20% depreciation of the closing exchange rate of the quarter against the reference currency, except for assets
and liabilities of foreign subsidiaries, when transacted in a currency equivalent to their respective functional currencies.
