12.              Specify the funds available for use pursuant to Article 7, paragraph 1, of CVM Instruction No. 567/15: The acquisition of shares under the Program shall be made through the debit of the balance available in the Company's Investment Reserve account, which according to financial statements for the fiscal year ended December 31, 2015, amounted to R$268,659,126.75.

13.              Name the reasons why the members of the Board of Directors feel confident that the repurchase of shares will not harm the discharge of obligations before creditors nor the payment of mandatory, fixed, or minimum dividends: The members of the Board of Directors understand that the current financial situation of the Company is compatible with the possible Program execution in the approved conditions and are comfortable that the stock buyback does not affect the fulfillment of obligations to creditors or the payment of mandatory dividends, calculated according to the applicable law and approved by the shareholders’ meeting.

The amount to be used in the possible buyback of up to 8,198,565 common shares would correspond to approximately between R$20,000,000.00 to R$25,000,000.00, considering the average prices of the last thirty days, an amount that is not material for the Company. Furthermore, such investment represents less than 3% of the cash equivalents according to financial statements for the fiscal year ended December 31, 2015.

The potential amount to be employed in the Program – considering the level of obligations to creditors – does not affect the full payment capacity of financial commitments , nor the payment of mandatory dividends.
