If Angra fails to deliver a written notice with its decision according to Section 2.1 above until Angra’s Decision Date, such failure shall be understood as Angra’s decision to maintain Estre shares and the Roll Up Right (as defined below) shall terminate automatically upon such failure.

Put Option Right. Irrespectively of Angra’s shareholding in Estre after the Capital Increase, in case Angra decides until the Angra’s Decision Date to maintain its Estre shares and not to adhere to the Transaction described in the BCA, Angra shall have the right to exercise its Put Option Right in accordance with the provisions established below:

within 180 (one hundred and eighty) days following the effective payment (integralização) of the Capital Increase (“Angra’s Put Option Exercise Period”), Angra shall deliver a written notice to the other Parties, in form and substance of Exhibit B hereto (“Put Option Amount Notice”), informing: (i) the Base Put Option Amount as calculated in accordance with Section 3.1 below; (ii) the bank account into which the Total Put Option Amount shall be deposited;

If Angra fails to deliver a written notice until the end of Angra’s Put Option Exercise Period, such failure shall be understood as Angra’s decision not to exercise its Put Option Right, which shall terminate automatically upon such failure.

Within 10 (ten) Business Days following the receipt of the Put Option Amount Notice, Estre and BR Holdco shall deliver a joint notice to Angra, in form and substance equal to Exhibit C hereto (“Response Notice”), informing: (i) whether or not they agree with the calculation of the Base Put Option Amount pursuant to the Put Option Amount Notice, provided that, any notice informing a disagreement shall provide the reason of such disagreement, and (ii) if they agree with the number of Estre Shares held by Angra that will be transferred to Estre and the exact number of Estre Shares held by Angra that will be transferred to BR Holdco, if applicable, in accordance to Section 2.2.4(A) below.

In case Estre and BR Holdco do not agree with any of the calculations provided by Angra in the Put Option Amount Notice, the Parties shall negotiate in good faith a solution to such disagreement and, in case they cannot reach an agreement within 10 (ten) Business Days following the receipt of Response Notice, the dispute shall be solved pursuant to Section 8.2.

Within, whichever occurs last, (i) 30 (thirty) Business Days following Put Option Amount Notice or (ii) 10 (ten) Business Days following an agreement or decision regarding the calculation of the Base Put Option Amount and/or the total number of Estre Shares which will be subject to the Fiduciary Lien as provided in Section 2.2.3 above, as applicable (the date when the transfer of Estre Shares held by Angra pursuant to the Put Option effectively occurs, the “Put Option Closing Date”), Angra, Estre and BR Holdco shall meet at the Put Option Closing Location to execute and deliver all documentation and take all other actions necessary to effect and formalize: (A) the transfer of Angra Shares to Estre (or to BR Holdco in case Estre cannot, due to legal reasons, acquire and/or hold the Angra Shares); and (B) the Fiduciary Lien (as defined below).

Roll Up Right. In case Angra decides until the Angra’s Decision Date to contribute all its Estre shares to Newco in exchange for Newco Shares instead of exercising its Put Option Right:

Angra shall contribute all its Estre shares to Newco in exchange for Newco Shares, in accordance with the Cooperation Agreement and Exhibit C, and comply with all the obligations applicable to each Estre Shareholder pursuant to the Cooperation Agreement and Exhibit C, as applicable, including, without limitation, the execution by Angra of (a) the Forfeiture and Waiver Agreement, (b) the Registration Rights and Lock-Up Agreement, and (c) the Equity Compensation Agreement (“Roll Up Right”).

Such sales shall be subject to the applicable Law, but not subject to contractual lock-up obligations and shall be performed at the sole discretion of Newco or the Mandated Bank, as applicable, based on their reading of market conditions. Upon the delivery of a Sale Request, Angra constitutes Newco or the Mandated Bank, as applicable, as its attorney with full power to perform any and all acts necessary to the sale of Newco Shares held by Angra and subject to the Sale Request.

Within 10 (ten) Business Days following the receipt of the Shortfall Notice, Angra shall deliver a notice to Newco, informing whether or not Angra agrees with the calculation of the Sale Price Shortfall pursuant to the Shortfall Notice, provided that, any notice informing a disagreement shall provide the reason of such disagreement.

If Angra agrees with the calculation of the Sale Price Shortfall, Newco shall pay to Angra the amount equivalent to the Sale Price Shortfall, by wire transfer of immediately available funds to Angra to such account(s) as shall be designated by Angra on the notice set forth by Section 2.4.4 above, within 90 (ninety) Business Days following the date of the receipt of such notice (“Shortfall Protection”).

For the avoidance of doubt, Newco’s obligation to pay the Shortfall Protection will only be applicable if the Selling Price (average price per Newco Share weighted by volume received by Angra in connection with the sale of Newco Shares during the Selling Period) received by Angra for the sale of Newco Shares during the Selling Period is less than the Base Put Option Amount per share. No amount of Shortfall Protection will be due by Newco if the Selling Price is equal or superior to the Base Put Option Amount per share.

The validity and effectiveness of any transfer of Estre Shares by any of the Parties prior to the payment of the Base Put Option Amount shall be subject to the execution of a joinder letter to this Agreement by the transferee (which transferee shall agree to be bound by all of the terms and provisions to this Agreement), effective as of the date such transferee acquires Estre Shares, in form and substance of Exhibit G hereto (“Joinder Agreement”).

In case any Party or Intervening Party (a “Transferor”) decides to transfer its Estre Shares to a Third Party (“Transferee”), the Transferor shall remain bound by the terms and conditions of this Agreement for the timely performance of the obligations that originally bound the Transferor until the Transferee executes and delivers the Joinder Agreement, when the Transferor shall cease to have any obligations related to this Agreement.

For the avoidance of doubt, any action taken pursuant to this Section 9.34 shall not affect and shall be deemed in addition to the obligations set forth in Estre Shareholders’ Agreement for the transfer of Estre Shares and shall not, in any way, be interpreted as limiting or modifying the obligations established in Estre Shareholders’ Agreement.

Irreversibility, Irrevocability and Binding Force. This Agreement is irrevocably and irreversibly executed by the Parties, binding upon the Parties, their heirs and successors and permitted assignees.

Headings. The headings in this Agreement are for reference only and shall not affect the interpretation of this Agreement.

Amendment and Modification and no Waiver. This Agreement may only be amended, modified or supplemented by an agreement in writing signed by all Parties and Intervening Parties hereto. No waiver by any party of any of the provisions hereof shall be effective unless explicitly set forth in writing and signed by the party so waiving. Except as otherwise set forth in this Agreement, no failure to exercise, or delay in exercising, any rights, remedy, power or privilege arising from this Agreement shall operate or be construed as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege.

Severability. If any term or provision of this Agreement is invalid, illegal or unenforceable in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any other term or provision of this Agreement or invalidate or render unenforceable such term or provision in any other jurisdiction. Upon such determination that any term or other provision is invalid, illegal or unenforceable, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the greatest extent possible.

Specific Performance of Obligations. The Parties establish, for all purposes of law, that this Agreement is an extrajudicial enforcement instrument (título executivo extrajudicial) under article 784, subparagraph III of the Brazilian Civil Procedure Code and that this Agreement allows for specific performance of the obligations assumed herein, in execution proceedings, when available under the Brazilian Civil Procedure Code or in arbitration (as provided in Section 8.2 above), without prejudice to any Party’s power to pursue indemnification in arbitration, alternatively or cumulatively to the specific performance of the relevant obligations.

Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed an original, but all of which shall together be deemed to be one and the same agreement. A signed copy of this Agreement delivered by facsimile, e-mail or other means of electronic transmission shall be deemed to have the same legal effect as delivery of an original signed copy of this Agreement.

Intervening Parties. Each of the Intervening Parties hereby expressly acknowledge and represent, irrevocably and irreversibly, for all legal purposes, that: (i) each Intervening Party has knowledge of the entire content of this Agreement; and (ii) each Party consents with the terms and conditions of this Agreement. For the avoidance of doubt, none of the Intervening Parties shall have any obligation under this Agreement.
