NOTICE TO STOCKHOLDERS

RE-PRESENTED ON JANUARY 29, 2014

This Notice to Stockholders was re-presented on January 29, 2014 to rectify the information in item ‘d’, which originally stated that the unit cost attributable to the shares issued in the stock dividend was R$ 5.00.

In the best interpretation now available to the Company, however, the said stock dividend is not among those described in Paragraph 1 of Article 47 of Normative Instruction 1.022/2010 of the Brazilian federal tax authority (Receita Federal do Brasil), since it is a stock dividend arising from capitalization of a capital reserve defined as ‘untaxed’; and as a result the unit acquisition cost attributed to the shares in the stock dividend is in fact R$ 0.00 (zero Reais).

Consequently this present Notice to Stockholders has been re-presented (below), with the original drafting of item ‘d’ now reading as follows:

“In the best interpretation available to the Company, in accordance with Paragraph 1 of Article 47 of Normative Instruction 1.022/2010 issued by the Brazilian federal tax authority (Receita Federal do Brasil), the unit acquisition cost attributed to the shares in the stock dividend is R$ 0.00 (zero Reais), since it is a stock dividend arising from capitalization of a capital reserve with ‘non-taxed’ status.”.

We hereby advise our stockholders that the Extraordinary General Meeting of Stockholders held on December 26, 2013 made the following decisions relating to stockholdings in the Company:

·                  CAPITAL INCREASE AND STOCK DIVIDEND:

(a)         Increase in the Company’s registered share capital

new nominal preferred shares, each with nominal unit value of R$ 5.00 (five Reais)

(b)         For shares traded on the BM&FBovespa S.A. (the São Paulo Stock, Commodities and Futures Exchange), the stockholders entitled to this benefit will be those who are holders of shares on December 26, 2013. The shares will trade ‘ex–‘ this benefit on December 27, 2012.

(c)          The shares arising from the stock dividend will be credited on January 3, 2014.

(d)         In the best interpretation available to the Company, in accordance with Paragraph 1 of Article 47 of Normative Instruction 1.022/2010 issued by the Brazilian federal tax authority (Receita Federal do Brasil), the unit acquisition cost attributed to the shares in the stock dividend is R$ 0.00 (zero Reais), since it is a stock dividend arising from capitalization of a capital reserve with ‘non-taxed’ status.

(e)          In accordance with Normative Instruction 168/91 of the Brazilian Securities Commission (Comissão de Valores Mobiliários – CVM), the amount resulting from the sale, in Reais, of the fractions resulting from calculation of the share bonus will be paid to the holders of those fractions together with the payment of the first installment of the dividend for the business year of 2013.

Stockholders whose shares are not held in custody by the CBLC and whose registration details are not up-to-date should visit any branch of Banco Itaú Unibanco S.A. (the Institution which administers Cemig’s Nominal Share Registry System), carrying their personal identification documents, for the necessary updating.

The Chair then asked the Secretary to read the Proposal of the Board of Directors, which deals with the agenda, the content of which is as follows:

“ PROPOSAL

BY THE BOARD OF DIRECTORS

TO THE

EXTRAORDINARY GENERAL MEETING OF STOCKHOLDERS

TO BE HELD ON JANUARY 30, 2014

Dear Stockholders:

The Board of Directors of Companhia Energética de Minas Gerais (Cemig),

– in view of the following facts and considerations –

a)             Cemig Geração e Transmissão S.A. (“Cemig GT”) has signed a share purchase agreement with Petróleo Brasileiro S.A (“Petrobras”), with the signature as consenting parties of Companhia Energética de Minas Gerais (Cemig) and Brasil PCH S.A. (Brasil PCH), such agreement governing acquisition (“the Transaction”) by Cemig GT or by a company in which it has an interest (“the Purchaser”) of the 49% of the common shares in Brasil PCH that were held by Petrobras (“the Brasil PCH Share Purchase Agreement”).

b)             The stockholders’ agreement of Brasil PCH provides for the possibility of the other stockholders exercising a right of first refusal in the event of disposal of the shares in Brasil PCH, or, further, a right of joint sale, or “tag-along right”.

c)              The Brasil PCH Share Purchase Agreement made it obligatory for the Purchaser to provide the right of tag-along and the right of first refusal to the other common stockholders of Brasil PCH – namely:  Eletroriver S.A. – (“Eletroriver”) (34.3%), BSB Energética S.A. (“BSB”) (14.7%) and Jobelpa S.A. (“Jobelpa”) (2%).

d)             At the demand of Cemig GT, exercise of the tag-along right by Jobelpa was stipulated in the Brasil PCH Share Purchase Agreement as a condition precedent for completion of the Transaction.

e)              the Board of Directors has authorized alteration of the total value of the Transaction,

in the event of acquisition of up to 100% of the common shares in Brasil PCH, if there is exercise of the right of tag-along by all the other stockholders of Brasil PCH.

f)               the Board of Directors authorized provision of a guarantee by Cemig of all the obligations and commitments under the Brasil PCH Share Purchase Agreement, under which Cemig would be jointly liable as principal debtor, and not merely as guarantor, to the same extent that, and on the same conditions as those on which, the Purchaser is liable (“the Surety Guarantee”).

g)              Clause 15.7 of the Brasil PCH Share Purchase Agreement allows assignment of the position, rights and obligations of Cemig GT under that Agreement, prior to the date of completion, at the exclusive option of Cemig GT, without the need for consent from Petrobras, to a company, already constituted or to be constituted, in which Cemig GT would have shares or unit shares representing at least 40% of the share capital, the surety guarantee given by Cemig remaining fully valid and in effect.

h)             Cemig GT entered into an Investment Agreement with RR Participações S.A. (“RR”), Light Energia S.A. (“Light”), Renova Energia S.A. (“Renova”) and Chipley SP Participações S.A. (“Chipley”), to provide, among other matters, for:

18

Table of Contents

i.      procedures for increase of the capital of Chipley, in such a way that Cemig GT would become holder of 40% of the voting and total stock of Chipley;

ii.     assignment of the Brasil PCH Share Purchase Agreement to Chipley;

iii.    increase in the capital of Renova, to be subscribed entirely by Cemig GT; and

iv.    acquisition of 51% or 100%, as the case may be, of the common shares in Brasil PCH by Chipley.

i)                 Concomitantly with the Investment Agreement, Cemig GT and Chipley entered into a Term of Assignment of the PCH Brasil Share Purchase Agreement, to which Cemig, Renova and Renovapar S.A. (“Renovapar”) were consenting parties, containing, among other commitments, the following:

i.      Commitment by Chipley to assume the position of the Purchaser of the Shares, becoming subrogated in all the rights and obligation of Cemig GT in the Brasil PCH Share Purchase Agreement, also taking on responsibility for all the costs and obligations assumed by Cemig GT in the process of negotiation, formalization, and conclusion of the acquisition of the shares in Brasil PCH.

ii.     The surety guarantee provided by Cemig in the Brasil PCH Share Purchase Agreement would remain valid and effective, thenceforth favoring Chipley.

iii.    Under a Counter-Guarantee Contract entered into on the same date by the same parties that signed the Term of Assignment of the Brasil PCH Share Purchase Agreement, Renova and Renovapar undertook that in the event that the guarantee given by Cemig is executed, they will assign all the shares that they hold in Chipley to Cemig or to whatever party Cemig may indicate, in consideration of a payment of R$ 1,200.00 (one thousand two hundred Reais), duly updated.

j)                On October 28, 2013, Petrobras sent notice to Chipley stating that, within the procedures for the disposal by Petrobras of its common shares in Brasil PCH, when the period for exercise of the first refusal and tag-along rights specified in the Stockholders’ Agreement of Brasil PCH had expired, the ‘Original Stockholding Block’, comprising the companies Eletroriver and BSB, had not given any notice to Petrobras in relation to exercise of those rights, resulting in release of Petrobras, by the Original Stockholding Block, to sell its shares to Chipley.

In relation to Jobelpa, Petrobras reported that on June 25, 2013 Jobelpa stated its desire to exercise its tag-along right, and had signed the Term of Adherence to the PCH Share Purchase Agreement (previously signed by Petrobras and Cemig GT, and assigned to Chipley).

k)             To regulate the acquisition by Chipley of the shares held by Jobelpa in Brazil PCH, it was in the interest of both parties that a specific share purchase agreement should be entered into, rather than their merely entering into a Term of Adherence to the Brasil PCH Share Purchase Agreement.

l)                 It was required that the transaction of purchase of the shares owned by Jobelpa should be submitted, for consent and approval, to the Brazilian monopolies authority (Conselho Administrativo de Defesa Econômica – CADE) and the Brazilian electricity regulator (National Electricity Agency, Agência Nacional de Energia Elétrica – Aneel), simultaneously with the process of approval and consent to the purchase of Petrobras’s shares, since the transactions were conditionally linked.

m)         The period for submission to Aneel of the request for consent to a transaction involving acquisition of the shares in Brasil PCH ran until November 4, 2013, since the notice referred to in “j” above was received on October 28, 2013.

n)             On November 1, 2013, Chipley and Jobelpa entered into a share purchase agreement (“the Jobelpa share purchase agreement”) governing the acquisition by Chipley of the 2% of the voting stock of Brasil PCH owned by Jobelpa, with Cemig as guarantor.

o)             As a consequence of the transaction involving exercise of a tag-along right, resulting from the disposal of the shares in Brasil PCH owned by Petrobras, the Jobelpa share purchase agreement contains the same obligations, rights and guarantees as the Brasil PCH Share Purchase Agreement: it is substantially the same as the Petrobras document, changing only the name of the purchaser, the name of the vendor, the percentage interest involved and the number of common shares, the acquisition price (the unit price of the share being maintained); and excluding the references not applicable to the Jobelpa share purchase agreement, such as the concession of the tag-along and first-refusal rights of the other stockholders of Brasil PCH.

p)             As well as the alterations above, the Jobelpa share purchase agreement will not have Brasil PCH as a consenting party. This is because participation by Brasil PCH with this status in the share purchase agreement signed with Petrobras was questioned by the stockholders of Brasil PCH that were members of the Original Block, who stated disagreement with the concept of Brasil PCH signing a contract in which it has no right or obligation.

q)             Since Eletroriver and BSB did not exercise the right of first refusal, and Jobelpa exercised only the tag-along right (right of joint sale), in relation to the common shares that it owned, the transaction has taken the form of an acquisition of 51% of the voting stock of Brasil PCH.

r)                Under Article 256 of Law 6404/1976, indirect acquisition by Cemig GT of control of Brasil PCH requires authorization by the General Meeting of Stockholders, since the purchase price constitutes a material investment for the Purchase, as specified in Article 247, sole sub-paragraph, of that Law.

19

Table of Contents

s)               The large quantity of the assets of Brasil PCH makes it impracticable to contract and carry out an assessment of the book value of that company at market prices, within the period between confirmation by Petrobras of the first refusal and tag-along rights and the closing of the transaction.

t)                It not being possible to evaluate whether or not the price paid for the shares of Brasil PCH exceeds one and a half times the book value of the company at market prices, as specified in Paragraph 2 of Article 256 of Law 6404/1976, consequently this circumstance confers the right to withdraw from the Company upon any stockholders that dissent at the General Meeting of Stockholders that decides on the indirect acquisition by Cemig GT of the control of Brasil PCH.

– now proposes to you the following:

1.         Orientation for the representative of the Company at the Extraordinary General Meeting of Stockholders of Cemig GT to be held on January 30, 2014, to vote in favor of :

a)       Ratification of the appointment, and contracting, of Ernst & Young Terco, CNPJ 59.527.788/0001-31, with head office in São Paulo at Avenida Juscelino Kubitschek 1830, Torre II, 6th Floor, CEP 04543-900, as the specialized company responsible for preparation of the Opinion on the Economic and Financial Valuation of the generation assets of Brasil PCH S.A., of April 22, 2013, for the purposes of Paragraph 1 of Article 256 of Law 6404/1976.

b)        Approval of the Valuation Opinion on Brasil PCH S.A., referred to above.

c)         Approval of the transaction that results in acquisition of 51% of the common shares of Brasil PCH S.A., an unlisted company with head office at Rua São Bento 8, 8th Floor, Centro, Rio de Janeiro, Rio de Janeiro State, CNPJ/MF 07.314.233/0001-08, its articles of association being filed with the Commercial Board of Rio de Janeiro State (Jucerja), under NIRE No. 33.300275-681, through Chipley SP Participações S.A., a company in which Cemig Geração e Transmissão (Cemig GT) owns 40% of the share capital.

2.         Authorization to concede the right of minority stockholders dissenting in this Extraordinary General Meeting of Stockholders to withdraw from the Company in the event of the situation referred to by Paragraph 2 of Article 256 of Law 6404/1976, that is to say, in the event that the price paid for the shares of Brasil PCH S.A. exceeds one and a half times the book value of that company, valued at market prices.

As can be seen, the objective of this proposal is to meet legitimate interests of the stockholders and of the Company, and as a result it is the hope of the Board of Directors that you, the stockholders, will approve it.

The Chair noted the presence at the meeting of Mr. Diego Moreira Alves, bearer of CPF 013725326-50, representative of Ernst & Young Terco Assessoria Empresarial Ltda., and made available a copy of the said Valuation Opinion, dated April 21 2013.

The Chair then put the Proposal made by the Board of Directors to debate and, subsequently, to the vote, and it was approved by majority of votes. The stockholder Schwab Fundamental Emerging Markets Large Company Index ETF voted against Item 2 of the proposal by the Board of Directors to the Meeting; and the representative of the stockholder Caixa de Previdência dos Funcionários do Banco do Brasil-PREVI voted against Item 1 of the Proposal and abstained in relation to Item 2 of that document.

There being no further business, the Chair opened the meeting to the floor, and since no-one wished to make any statement, ordered the session suspended for the time necessary for the writing of the minutes. The session being reopened, the Chair, after putting the said minutes to debate and to the vote and verifying that they had been approved and signed, closed the meeting.

For the record, I, Anamaria Pugedo Frade Barros, Secretary, wrote these minutes and I sign them together with all those present.

(Brasil PCH S.A. is an unlisted corporation with head office at Rua São Bento 8, 8th floor, Centro, in Rio de Janeiro, Rio de Janeiro State, registered in the CNPJ/MF under N° 07.314.233/0001-08, with articles of association filed at the Commercial Board of the State of Rio de Janeiro (‘Jucerja’), under NIRE 33.300275-681.)

1.              Right to withdraw; amount of reimbursement

As set out in items (s) and (t) of the proposal which the Board of Directors submitted to the EGM, and which the EGM approved:

Since the Acquisition is an investment of material scale, and valuation of the Stockholders’ equity of Brasil PCH at market prices would not be practicable in the required time – making it impossible to evaluate whether or not the price per share payable for the shares of Brasil PCH exceeds one and a half times the value per share of the Stockholders’ equity of Brasil PCH,

Cemig has adopted the view that Paragraph 2 of Article 256 of the Corporate Law (Law 6404, as amended) is applicable to the Acquisition, and that as a result any stockholders that dissent from the decisions taken at the EGM will have the right to withdraw from the Company, with reimbursement of the value of their shares. This applies as follows:

Dissenting stockholders that have the right to withdraw (“qualified stockholders”) are those that:

·                  held common or preferred shares on June 14, 2013 (date of publication of the Material Announcement giving notice of the transaction) – with the exception of any shares that were traded on that day itself; and

·                  maintain ownership of those shares without interruption up to the date of the actual exercise of the right to withdraw.

Cemig studies privatization of Colombian generator Isagen

Cemig (a listed company with securities traded on stock exchanges of São Paulo, New York and Madrid), in line with its commitment to best corporate governance practices, and in accordance with CVM Instruction 358 of January 3, 2002 as amended, hereby reports to stockholders and the market as follows:

Cemig is studying the possibility of participating in the process of privatization of Isagen S.A. E.S.P. (“Isagen”), conducted by the Colombian government.
