Table of Contents

Table of Contents

The Ordinary Shareholders’ Meeting held on April 27, 2018 approved the distribution of R$257,750,384.59 (two hundred and fifty-seven million seven hundred and fifty thousand three hundred and eighty-four Brazilian reais and fifty-nine centavos), as minimum compulsory dividends.

For your references, the Company’s financial statements related to the business year ended on December 31, 2017 and the relevant Management’s Report, disclosed on January 29, 2018, were drawn up by the Company’s Board of Executive Officers, audited by the independent auditors BDO RCS Auditores Independentes S/S and approved by the Ordinary  Shareholders’ Meeting held on April 27, 2018. The Company disclosed, on October 24, 2018, its quarterly financial statements related to the 3 rd  quarter of 2018.

Considering the existing balance in the Company’s Reserve for Investments on September 30, 2018, in the amount of R$ 2,783,319,849.66 (two billion seven hundred and eighty-three million three hundred and nineteen thousand eight hundred and forty-nine reals and sixty-six centavos), and due to the Company’s cash generation, the Management proposes the distribution of interim dividends on an extraordinary basis, in the total amount of R$2,783,319,849.66 (two billion seven hundred and eighty-three million three hundred and nineteen thousand eight hundred and forty-nine reals and sixty-six centavos), equivalent to R$5.030371757 per share issued by the Company.

The amount of dividend per share as subject to a variation derived of adjustments on the balance of treasury shares up to the extraordinary general meeting.

The interim dividends will be declared and paid against the Company’s account of Reserve for Investments, approved by the Ordinary  Shareholders’ Meeting held on April 27, 2018 and registered in the Company’s quarterly financial statements of September 30, 2018.

The amount to be distributed as interim dividends on an extraordinary basis corresponds to, approximately, 100% (on hundred percent) of the total amount existing in the Company’s Reserve for Investments. In this regard, and considering the cash generation of the Company in the fiscal year of 2018, higher than expected, the Management of the Company informs that the distribution of such amount will not cause any adverse effect in its business plan or in its future perspective of investments.

It is also proposed that the declared interim dividends are paid to the shareholders of the Company, in one installment, up to the end of the current fiscal year in a date to be decided by the Shareholders’ Meeting.

The shareholders holding shares issued by the Company on the reference date defined by the Shareholders’ Meeting shall be entitled to the interim dividends declared, in accordance with the above terms, in the total amount of R$ 2,783,319,849.66 (two billion seven hundred and eighty-three million three hundred and nineteen thousand eight hundred and forty-nine reals and sixty-six centavos), corresponding to 100% (one hundred percent) of the Company’s Reserve for Investments.

service providers shall be carried out up to 7 (seven) days before the date of the Shareholders’ Meeting, that is, until November 26, 2018, including.

If the shareholder has not deposited in advance the proxy and representation instruments mentioned above, he may attend the General Meeting, provided that he appears with the original documents proving his powers.

The Company requires that powers of attorney for representation at the General Meeting indicate the place where they were passed, the complete qualification of the grantor and of the grantor, the date and purpose of the granting with the designation and the extension of the powers conferred, and the acknowledgment of signature of the respective signatory.

Documents of the shareholders issued abroad that come from countries that are signatories to the Hague Convention must pass the apostille affixation in the form of specific regulations, and documents of the shareholders issued abroad that come from countries that are not signatories to the Hague Convention must contain acknowledgment of signatures by Public Notary and pass through the legalization in Brazilian Consulate. In both cases, the documents must be translated by a sworn translator registered with the Commercial Registry and registered in the Registry of Deeds and Documents, in accordance with the legislation then in force.
