   "Subject: Request for clarification on news

   Dear Officer,

5. In reference to the news published on 09.15.2017, in the journal Brasil 247, under the title "Eletrobras employees denounce Lemann's invisible hand in privatization", follows a summary of certain statements:

   "Eletrobras employees sent 247 material about the hidden agent of Eletrobras' privatization that would be connected to Equatorial Energia, which has connections with the billionaire Jorge Paulo Lemann. Days ago, journalist Luis Nassif denounced Lemann's controversial participation in Eletrobras' privatization, which would be the deal of the century.

   Below, is the text about the hidden agent of privatization:

   Eletrobras: Better late than never... the overdue resignation of Oscar Salomão

   Tonight, September 14, 2017, Mr. Oscar Salomão Filho left his office on the 12th floor of the Eletrobras Building at Avenida Presidente Vargas. Oscar Salomão was a key man in many privatizations of the electric sector in the 90's and in this decade (CEMAR, CTEEP, CELPA, CESP, AES, CELG-D see Linkedin below), and today he was Wilson Pinto, Eletrobras' CEO, right-hand man. Oscar was also leading Eletrobras' privatization until his exoneration along with several other assistants in commissioned positions. A judicial order from the 6th Labor Court of Brasilia, 10th Region, regarding the process 0762/2013, determined the exoneration of political nominees in commissioned positions, which took place on August 14, 2017. Right after, on August 21, Eletrobras appointed Mr. Oscar as CEO of Eletropar, a subsidiary of Eletrobras with less than 10 employees. This nomination has not been approved by MME yet, therefore, Oscar does not hold a post at Eletrobras.

   Oscar did not want to waste time, so he kept on working even after his exoneration. He worked without receiving any salary, in an irregular and illegal condition, since he has no further connection with Eletrobras. And it's not a ordinary job, since he has access to the company's strategic data and he is leading Eletrobras teams in meetings at BNDES regarding the privatization.

   Yesterday, September 14, 2017, he was in a meeting with Dr. Lidiane Gonçalves, from the BNDES Privatization area. The president of Eletrobras, Mr. Wilson Pinto, assured Dr. Lidiane that Oscar was there as an employee of Eletropar. Although the nomination has taken place, Oscar's nomination has not yet materialized. The meeting occured normally, even though his nomination has not been confirmed in the official gazette and that Eletropar has no relation with Eletrobras' privatization.

   The Unions and Eletrobras' Workers Association informed today, 09/14/2017, through this letter, that they have already denounced the irregular performance of Oscar for the Public Prosecutor's Office. They also plan to file a lawsuit to overturn all decisions made at meetings where Oscar was irregularly present.

   Now, it is probable that Oscar will no longer play any role in Eletrobras' privatization, since even if his indication to act as CEO of Eletropar materializes, it would be very difficult for the companies to justify his continuity.

   Oscar is conected to Equatorial Energia, he is currently a member of CEMAR's board of directors. Equatorial has always had an interest in Eletrobras' distribution companies, particularly CEPISA, and has already publically expressed its interest in several SPEs in which Eletrobras has a participation.

   [...]".
