EXPLANATIONS on GAE/SRE–2629/08, of November 5, 2008

Question asked by the CVM:

Considering the terms of the Market Announcement of November 04, 2008, we request you to inform us, for the purposes of orientation of the market, whether the acquisition, through the jointly-controlled subsidiary Empresa Amazonense de Transmissão de Energia S.A. – EATE, of 80% of the registered capital of Lumitrans – Companhia Transmissora de Energia Elétrica and 80% of the registered capital of STC – Sistema de Transmissão Catarinense S.A will produce for the stockholders of Companhia Energética de Minas Gerais – Cemig the right to withdraw as specified in Article 256 of Law 6404/76, as amended by Law 10.303/01.

If so, please give this information:

·              Which stockholders will have the right to state an opinion, that is to say, stockholders of record on what day will have the right to dissent from the decisions of the General Meeting of Stockholders to be called for approval or rectification of the transaction?

·              The amount of the reimbursement, in R$ per share.

·              The period and the procedures that dissenting stockholders should adopt to enable them to state their positions.

Reply by Cemig:

Dear Sirs,

In response to the official request referred to above, we hereby inform the public that the transaction of acquisition, by Empresa Amazonense de Transmissão de Energia S.A. – EATE, of 80% of the registered capital of STC – Sistema de Transmissão Catarinense S.A does not give the stockholders of Companhia Energética de Minas Gerais – Cemig the right to withdraw, as referred to in Article 256 of Law 6404/76, as amended by Law 10303/01, since Cemig holds only 25% of the voting stock, and 16.89% of the total shares: this holding does not give Cemig total control over the operations of that company.

Additionally, EATE (Empresa Amazonense de Transmissão de Energia S.A.) is not a listed company, and hence Article 256 of Law 6404 of 1976 does not apply to it.

Hoping to have met your requests satisfactorily, we remain available for any further explanations that may be necessary.

Belo Horizonte, November 7, 2008

Yours,
