The Debentures of the respective Series redeemed under the terms of this item will be canceled by the Issuer. In this alternative, to calculate the Remuneration of the respective Series to be redeemed, for each day of the period in which there is an absence of rates, the last officially disclosed DI Rate will be used. 4.12.3 If the DI Rate or its legal substitute, as the case may be, is again disclosed before the General Meetings of Debenture Holders of the respective Series referred to in Clause 4.11.5 above, said General Meeting of Debenture Holders will not be held and the DI Rate or its legal substitute, as of its disclosure, will be used again for the calculation of any obligations provided for in this Indenture, it being understood that until the date of disclosure of the DI Rate or its legal substitute, the last DI Rate or its legal substitute disclosed will be used for the calculation of any obligations provided for in this Indenture.

K = Order number of DI Rates, ranging from "1" (one) to "n". TDIk = DI rate, of order "k", expressed per day, calculated to 8 (eight) decimal places with rounding, as follows: where: DIk = DI rate, of order "k", disclosed by B3, valid for one (1) Business Day (overnight), used with two (2) decimal places; and Spread Factor = Fixed interest surcharge, calculated to nine (9) decimal places, with rounding, calculated as follows: J=VN e* (InterestFactor−1) InterestFactor=(DIFactor * SpreadFactor) DIFactor Docusign Envelope ID: 52DC1351-0909-8F13-8014-F8BE1942FF96 6 where: Spread = [●],[●][●][●][●]. DP = It is the number of Business Days between the Profitability Start Date or the immediately preceding Remuneration Payment Date (inclusive) and the calculation date (exclusive), “DP” being an integer; Notes: 4.12.1.1 The daily factors (1 + TDIk) are produced, and for each accumulated daily factor, the result is truncated to 16 (sixteen) decimal places, applying the next daily factor, and so on until the last considered; 4.12.1.2 If the daily factors are accumulated, the resulting "DI Factor" will be considered with 8 (eight) decimal places, with rounding; 4.12.1.3 The factor resulting from the expression (DI Factor x Spread Factor) is considered with 9 (nine) decimal places, with rounding; 4.12.1.4 The DI Rate must be used considering the same number of decimal places disclosed by the body responsible for calculating it; and 4.12.1.5 the DI Rate shall be used considering the identical number of decimal places disclosed by B3." 1.2 Finally, in view of the Bookbuilding Procedure, the Parties resolve to exclude Clauses 2.3.2, 3.4.2, 3.4.3, 3.8.2, 3.10, 4.8.2, 4.11.1.1 and 4.11.2.1 from the Indenture. 2 General Provisions 2.1 The terms and conditions of the Indenture that have not been expressly amended by this First Amendment are hereby ratified and remain in full force and effect.
