The Company's Board of Directors set the price per Share at R$18.75 (the "Price per Share") following the conclusion of the bookbuilding process and approved an increase in the limit of the Company's authorized capital stock to R$4,100.8 million, divided into 303,934,060 shares.

In accordance with CVM regulations, the total number of Shares initially offered in the Secondary Offering was upsized by 20% of the total number of Shares initially offered, or 22,222,222 Shares, at the Price per Share (the "Additional Shares"). The Additional Shares were offered by the Selling Shareholder.

The beginning of trading of the Shares on the São Paulo Stock Exchange (B3 S.A. - Brasil, Bolsa, Balcão) is scheduled to occur on July 15, 2019, and the settlement of the Offering is scheduled to occur on July 16, 2019.

The Restricted Offering has not been and will not be registered under the Securities Act, or any other U.S. federal or state securities laws, and the Shares may not be offered, sold, pledged or otherwise transferred in the United States or to U.S. investors, unless they are registered, or exempt from, or not subject to, registration under the Securities Act.

In order to comply with CVM Instruction 476 and to ensure the participation of current shareholders in the Restricted Offering, a priority right was given to existing shareholders of the Company to subscribe for up to all of the Shares placed through the Primary Offering pro rata to their shareholdings in the Company's

capital (the "Priority Offering"). Therefore, pursuant to the Priority Offering, all of the Shares offered in the Primary Offering were offered to all of the existing shareholders of the Company before any other investors.

Accordingly, the Priority Offering was only available to investors in the United States or to U.S. persons in reliance on exemptions from registration provided under the Securities Act.
