The other matters dealt with at this meeting have been omitted from this certificate, out of legitimate caution, supported by the Administration's duty of secrecy, in accordance with the caption of article 155 of Law no. 6.404/76, since they relate to interests that are merely internal to the Company, and therefore fall outside the scope of the rule contained in paragraph 1 of article 142 of the aforementioned Law.
