Investors of the target public of the Offering, including:

(iv)      spouses, personal partners, relations of prior generations, descendants or relations of the same generation up to the second degree, of any of the people referred to in items (i) to (iii) above (jointly, “Related Parties”), who may subscribe Debentures of the First Series, Debentures of the Second Series and/or Debentures of the Third Series without any upper limit as a proportion of the total of Debentures offered.

If an excess of demand takes place that is greater than 1/3 (one-third) of the Debentures, placement of Debentures with investors who are Related Parties will not be permitted, and the investment intentions presented by investors who are Related Parties shall automatically be cancelled, in accordance with Article 55 of CVM Instruction 400.

Potential investors should be aware that participation in the Bookbuilding Procedure by investors who are considered to be Related Parties may cause inappropriate formation of the final rate of remuneration of the Debentures and have an adverse impact on the liquidity of the Debentures in the secondary market. For additional information, potential investors should read the risk factor “Participation in the Offering by investors who are considered to be Related Parties may cause inappropriate formation of the final remuneration rate of the Debentures, and could have an adverse effect on the liquidity of the Debentures in the secondary market” in the section “Risk factors related to the Offering” on page 77 of the Preliminary Prospectus.

If non-publication of the IPCA Index takes place for a period of more than ten consecutive days after the expected date for its calculation and/or publication, or, further, in the event of its being abolished or of it being legally impossible to apply it to the Debentures of the Third Series, or if by order of a Court, then a general meeting of Debenture Holders of the Second Series and/or a general meeting of Debenture Holders of the Third Series shall be called for decision, by common agreement with the Issuer, on a new parameter to be used for the purposes of calculation of the Monetary Updating that will be applied, subject to the provision in the related issue deed of the Debentures.

If there is no agreement on the new parameter between the Issuer and the debenture holders of the Second Series and/or the debenture holders of the Third Series, the Issuer shall redeem the totality of the Debentures of such series, within up to thirty calendar days from the date of the holding of the related general meeting, subject to the provision in the respective issue deed of the Debentures.

In addition, in the event that a general meeting of debenture holders does not come into session, for lack of quorum, the Fiduciary Agent shall declare immediate early maturity of all the obligations arising from the Debentures, and shall immediately send the Issuer a communication in writing informing it of such event.

MARKET ANNOUNCEMENT

Cemig in Brazil’s Carbon Efficient Index for the index’s third year

Cemig (Companhia Energética de Minas Gerais), a listed company with securities traded on the stock exchanges of São Paulo, New York and Madrid, in accordance with CVM Instruction 358 of January 3, 2002, as amended, hereby publicly informs the Brazilian Securities Commission (CVM), the São Paulo Stock, Commodities and Futures Exchange (BM&F Bovespa S.A.) and the market in general, that:

For the third consecutive year since the index was created, Cemig (Companhia Energética de Minas Gerais) has been included in the portfolio of Brazil’s Carbon Efficient Stock Index — ICO2 (Índice Carbono Eficiente). The ICO2, created and developed by BM&FBOVESPA and the BNDES (Brazilian Development Bank), includes the shares of companies in Brazil’s IBrX-50 stock index that have the highest share-weighted ratios of gross revenue per unit of greenhouse gases emitted — providing an indicator of their carbon emission efficiency.

The new portfolio of the ICO2, in effect from January 7, 2013, has 36 shares of 35 companies. Cemig has increased its participation in relation to the IBrX-50, from 1.227% to 2.167% — a demonstration of its efficiency in terms of carbon emissions.

Cemig prepared its inventory of greenhouse gas emissions according to the ISO 14.064-1 standard and the specifications of the Brazilian Program of the GHG Protocol, and submitted it for independent verification — providing the enhanced credibility of the numbers reported in the ICO2.

Cemig’s significant participation in the ICO2 reflects its commitment to action on climate change, as expressed in its public commitment document “10 Initiatives for the Climate”. See: http://www.cemig.com.br/Sustentabilidade/MudancasClimaticas/Documents/CircularMudancasClimaticas.pdf

Cemig has also been recognized by the Carbon Disclosure Project (CDP), an NGO that holds the world’s largest corporate database on climate change, as one of the 10 Brazilian companies taking the most effective measures to mitigate climate change effects.
