4.3.   The resolutions of the Board of Directors are binding upon the Company and the companies controlled by the Company in relation to the matters connected to the Plan and its Programs.

5.        Restricted Share Awards

5.1.   The Company's Board of Directors and the governing bodies of the companies controlled by the Company, when applicable, may annually approve the grant of Restricted Shares within the scope of each Program, and shall determine the Eligible Persons on whose behalf the Restricted Shares may be granted under this Plan and the respective Program.

5.2.   The Eligible Persons may participate in and be entitled to grants of Restricted Shares of one or more Programs simultaneously, based on the criteria defined in each Program.

5.3.   The grant of the Restricted Shares will be made upon and subject to the execution of Award Agreements between the Company or the companies controlled by the Company and the Participants, which shall specify, without prejudice to other conditions determined by the Board of Directors and the governing bodies of the controlled companies, when applicable, the number of Restricted Shares subject to the award, as well as the terms and conditions of the vesting of rights related to the Restricted Shares.

5.3.1. The Company may transfer treasury shares to companies controlled by the Company, exclusively for the purpose of complying with the Plan, in compliance with the pertinent legislation and regulations.

5.4.   The granting of Restricted Shares will be subject to the voluntary acquisition by the Participants of Owned Shares, as provided in Clauses 5.4.1 to 5.4.3 below, and also considering Clause 8.5 below

5.4.1. The Eligible Persons may voluntarily invest with their own financial resources the minimum of 10% and maximum of 20% of the gross amount of their PLR in the acquisition of Owned Shares and must formalize, in case they opt to participate in the Plan, by means of the Award Agreement, their firm investment intention amount (“Firm Investment Intention Amount”) to purchase Owned Shares, observing such limits.

5.4.2.          Once the Participant has expressed its desire to participate in a Program and once the respective Award Agreement has been signed, the Participants must prove investment made in compliance with the terms and conditions of item 5.4.1 above agreed upon in the Award Agreement the full and lawful beneficial ownership of the Owned Shares acquired during the Acquisition Period, by delivering to the Company a statement from the custodian agent confirming ownership of the Owned Shares, observed item 5.4.3 below.

5.4.2.1. The Acquisition Period to be determine in the Award Agreement may be suspended in cases in which there is a legal or regulatory impediment to an acquisition of the Owned Shares by the Participant.

5.4.3. The Company may, for the purposes of managing this Plan, retain a brokerage firm, which shall be used by the Participants to acquire the Owned Shares and keep them under their uninterrupted ownership from the date of its acquisition until the end of the Waiting Period. If no brokerage firm has been engaged by the Company at a Participant’s location, said Participant shall prove the full and lawful beneficial uninterrupted ownership of the Owned Shares from the date of its acquisition until the end of the Waiting Period, by delivering the documents requested by the Company or by the companies controlled by the Company.

5.4.4. The goal of the Plan is to award for each one (1) Owned Share two (2) Restricted Shares. However, the Board of Directors may define, in an exceptional and justified manner, for each Program, a different number of Restricted Shares to be delivered for each Owned Share pursuant to the terms and conditions of the applicable Award Agreement, in compliance with the minimum of one (1) Restricted Share and the maximum of three (3) Restricted Shares for each one (1) Owned Share, based on an analysis by the Board of Directors in its sole discretion of the following indexes: (a) the Company’s performance during the fiscal year immediately preceding the execution of the Award Agreements; (b) the challenge level expected for the Company on the 3 fiscal years following the approval of the Program; and (c) the value of the Restricted Shares traded at B3 on the date of approval of each Program.

5.4.4.1. In the cases of the Excepted Participants, the number of Restricted Shares to be granted to such Excepted Participants shall be calculated by multiplying (i) the multiple determined in 5.4.4 above; by (ii) the Firm Investment Amount of said Participant divided by the average price paid to purchase Owned Shares of the remaining Participants, excluding the Excepted Participants of the respective Program.

5.5.   The transfer of the Restricted Shares to the Participants shall only take place upon the satisfaction of the conditions and terms set forth in this Plan, in the Programs and in the Award Agreements, such that the execution of an Award Agreement and the grant of Restricted Shares thereunder itself does not ensure the Participants any rights to the Restricted Shares nor does it represent the guarantee of their receipt.

5.6.   Until the Restricted Shares are effectively transferred to the Participants, under the terms of this Plan, respective Programs and Award Agreements, the Participants shall have no shareholder rights or privileges in relation to such Restricted Shares, specially, right to vote or receive dividends or interest on capital in relation to the Restricted Shares.

5.7.   The Award Agreements shall be individually executed by each Participant, provided that the terms and conditions defined in this Plan and in the respective Program are complied with.

6.        Shares Subject to the Plan

6.1.   The Participants may receive, within the scope of this Plan, shares and/or depositary receipts representing shares issued by the Company negotiated abroad, representing at most one and a half percent (1.5%) of the entire share capital of the Company on the date hereof, which may be adjusted under Clause 10.2 of this Plan, observed the applicable legal and regulatory provisions.

6.2.   With the purpose of consummating the grant of Restricted Shares under this Plan, the Company or the companies controlled by the Company shall, subject to applicable laws and regulations, transfer the Restricted Shares by means of a private transaction pursuant to the terms and conditions of the applicable Award Agreement.

6.3.   The Restricted Shares acquired under this Plan shall maintain all rights pertaining to their class, except for any provision otherwise set forth by the Board of Directors.

6.4.    The Participants shall undertake, in the Award Agreements, to comply with the applicable legislation and the Company’s other policies when trading their Owned Shares and Restricted Shares.

7.        Vesting of Rights Related to the Restricted Shares

7.1.   Without prejudice to other conditions set forth in the Programs and respective Award Agreements, the rights of the Participants pertaining to the Restricted Shares, especially the right to own such shares, shall only be fully vested if the Participants, (i) continuously remain Members of the Company or companies controlled by the Company for the entire Waiting Period and, cumulatively, (ii) maintain uninterrupted ownership of the Owned Shares from the date of their acquisition until the end of the Waiting Period.

7.2.   The number of Restricted Shares to which the Participants shall be entitled after the Waiting Period shall be reduced in the amount equal to the amount of applicable taxes and similar withholding obligations due by the Participant that have to be withheld pursuant to applicable legislation.

7.3.   Once the conditions set forth in Clauses 7.1 above and in the applicable Award Agreement are fulfilled, and provided that the requirements set forth in law and regulations are observed, the Company or companies controlled by the Company shall transfer, through a private transaction, to the Participants’ names within sixty (60) days, the number of Restricted Shares to which the Participants are entitled, provided that the provisions of Clauses 5.4.4.1 and 7.2 above are observed. Except for taxes and similar withholding obligations that will be withheld, as determined by Clause 7.2 above, the Company and/or the companies controlled by the Company, as the case may be, shall bear any costs incurred to transfer such Restricted Shares to the Participants. In the event it is not possible to deliver said Restricted Shares to the Participants, the Company and/or the companies controlled by the Company, when applicable, may pay to the Participants, with immediately available funds, in the currency of their respective locations of practice of the Participant, the amount equal to the granted Restricted Shares considering the Reference Price of the Restricted Shares, net of any applicable taxes and similar withholding obligations.

7.4.   In addition to the determinations of the Clause 8 below, the right to receive the Restricted Shares under this Plan, the respective Program and the applicable Award Agreement shall automatically terminate with no right to indemnification, ceasing all effects, if the Company is wound up, liquidated or is adjudicated bankrupt.
