PROPOSAL

BY THE BOARD OF DIRECTORS TO THE

EXTRAORDINARY GENERAL MEETING OF STOCKHOLDERS

TO BE HELD ON NOVEMBER 27, 2017 AT 11 A.M.

Dear Stockholders:

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

Whereas:

a) | On May 31, 2016, Cemig pledged:

55,234,637 (fifty five million two hundred thirty four thousand six hundred thirty seven) common shares and 110,469,274 (one hundred ten million four hundred sixty nine thousand two hundred seventy four) preferred shares in Transmissora Aliança de Energia Elétrica S.A. (‘Taesa’), at that time representing value of

R$ 1,075,000,000.00 (one billion seven hundred fifty million Reais),

in guarantee of obligations it assumed in favor of the banks holding a put option (‘the Put Option’) on

shares in Parati S.A. – Participações em Ativos de Energia Elétrica (‘Parati’);

and further offered to support that guarantee with its equity interest of 26.06% in Light S.A. (‘Light’);

and on August 30, 2016 an Extraordinary General Meeting of Cemig enabled postponement of the date of exercise of the Put Option from its original date (the last business day of the sixtieth month following the date of subscription of the shares in Parati) until November 30, 2017, (the last business day of the seventy seventh month); having reference also to a decision of the Board of Directors of May 30, 2016;

b) | on August 28, 2016 Cemig sent correspondence to the banks holding the Put Option (‘the Banks’), namely

Banco Santander (Brasil) S.A. (‘Santander’),

BV Financeira S.A. – Crédito, Financiamento e Investimento (‘BV Financeira’),

BB–Banco de Investimento S.A. (‘BB–BI’) and

Banco BTG Pactual S.A. (“BTG”) –

– | requesting release of the pledge that had been given, on the following shares in Taesa:

18,411,545 (eighteen million four hundred eleven thousand five hundred forty five) common shares and

36,823,090 (thirty six million eight hundred twenty three thousand ninety) preferred shares –

– | to make it possible to carry out a follow-on transaction, jointly with

Fundo de Investimentos em Participações Coliseu (‘FIP Coliseu’),

in a secondary public offering of Units in Taesa, with restricted efforts in Brazil under CVM Instruction 476, and international efforts under Rule 144A and Regulation S of the US Securities Act;

c) | on November 30, 2016 BTG exercised the Put Option in the ‘First Exercise Window’, under the Stockholders’ Agreements of the successors of Parati –

Luce Empreendimentos e Participações S.A. (‘Lepsa’) and

Rio Minas Energia Participações S.A. (‘RME’) –

Av. Barbacena 1200 |  | Santo Agostinho |  | 30190-131 Belo Horizonte, MG |  | Brazil |  | Tel.: +55 31 3506-5024 |  | Fax +55 31 3506-5025

| – | as a result of which Cemig acquired the following shares previously held by BTG:

76,817,097 (seventy six million eight hundred seventeen thousand ninety seven)

preferred shares in Lepsa, and

76,817,097 (seventy six million eight hundred seventeen thousand ninety seven)

preferred shares in RME

| – | as a result of which BTG ceased to be a stockholder in Parati;

d) | on September 1, 2017 the exercise value of the Put Option was

R$ 1,560,016,041.42 (one billion five hundred sixty million sixteen thousand forty one Reais forty two centavos),

in which the component of principal was

R$ 921,047,584.94 (nine hundred twenty one million forty seven thousand five hundred

eighty four Reais ninety four centavos),

the component of remuneration was

R$ 335,075,058.58 (three hundred thirty five million seventy five thousand fifty eight Reais fifty eight centavos),

and the gross-up factor represented

R$ 303,893,397.90 (three hundred three million eight hundred ninety three thousand three hundred

ninety seven Reais ninety centavos);

e) | on September 15, 2017, the remaining banks holders of the Put Option notified Cemig of their intention to exercise the Put Option on all the shares they hold in RME and Lepsa, pursuant to their rights under the Stockholders’ Agreement as signed by Cemig, Santander, BV Financeira and BB-BI, with RME and Lepsa as consenting parties, the amount to be paid by November 30, 2017;

f) | in this situation it becomes essential to extend the date for exercise of the Put Option, so as to avoid

| (i) | Light becoming state-controlled, an event which could give rise to early maturity of several of Light’s financing contracts, which have cross-default clauses; and

| (ii) | an accentuated fall in the stock price of its shares, which would be negative for the Banks referred to, since one of the guarantees of the Put Option would lose value;

g) | extension of the exercise date of the Put Option is conditional upon prior authorization by the stockholders of Cemig in an Extraordinary General Meeting.

– do now propose to you as follows:

• | Re-ratification of the decision taken by the Extraordinary General Meeting of May 30, 2016, altering its terms so as to postpone the date of exercise of the Put Option granted by Cemig on April 11, 2011 to:

Redentor Fundo de Investimento em Participações (‘FIP Redentor’)

(succeeded by Banco Santander S.A. (Brasil)),

BV Financeira S.A. – Crédito, Financiamento e Investimento (‘BV Financeira’), and

BB – Banco de Investimento S.A. (‘BB–BI’).

As can be seen, the objective of this proposal is to meet the legitimate interests of the stockholders and of the Company, and for this reason it is the hope of the Board of Directors that it will be approved.

MARKET INFORMATION

Cemig: Financial update

Cemig (Companhia Energética de Minas Gerais), a listed company with securities traded on the stock exchanges of São Paulo, New York and Madrid, in compliance with Article 12 of CVM Instruction 358 of January 3, 2002 as amended, hereby reports to the Brazilian Securities Commission (CVM), the São Paulo Stock Exchange (Brasil, Bolsa, Balcão – B3) and the market as follows:

As widely publicized at, and since, Cemig’s 22nd Annual Meeting with the Capital Markets, on June 1, 2017, Cemig is working successfully on execution of its plan to improve its capital structure, increase its operational cash flow generation, and diversify its sources of finance.

The plan is based primarily on the following lines of action:

| • |  | Reprofiling of debt:

This is in negotiation with the main creditor banks, for a total of R$ 4 billion, with approximate maturity of five years, and grace period of up to 18 months.

This has been approved by the Company’s governance.

| • |  | International debt issue:

An issue of debt outside Brazil of approximately US$1 billion.

This has been approved by the Company’s governance.

| • |  | Capital increase:

Increase in the Company’s share capital by R$ 1.3 billion, through subscription of shares.

(Approved by the EGM of October 26, 2017.)

| • |  | Sale of shares:

A proposed solution for the Put options related to Light, through sale of shares held outside the controlling block of the investee company.

| • |  | Disinvestment program:

Cemig has various processes of disinvestment in progress.

Highlights are the processes for the sale of its equity interests in Santo Antônio Energia, Light and Renova. The stage of these processes is in line with timing considered to be appropriate for M&A transactions for disposal of interests in companies of this scale.

| • |  | Operational efficiency:

1,948 employees accepted the Voluntary Retirement Programs implemented in 2016 and 2017 – resulting in a reduction in costs of approximately R$ 450 million per year.

In addition to the above, there are also the following significant factors:

Financial expenses: The reduction in the Selic interest rate has made a substantial contribution to reduction of Cemig’s financial

expenses.

Cash flow: Payment of debt of approximately R$ 1 billion in 2017 is a demonstration of Cemig’s economic strength and

cash flow generation capacity.

Tariffs: The Periodic Tariff Review scheduled for May 2018 will also contribute to increase in the Company’s cash

generation.

Cemig will keep its stockholders and the market opportunely and appropriately informed on developments on this subject.

Cemig (Companhia Energética de Minas Gerais), a listed company with securities traded on the stock exchanges of São Paulo, New York and Madrid, as per CVM Instruction 358 of January 3, 2002, as amended, hereby informs the Brazilian Securities Commission (CVM), the São Paulo Stock Exchange (Brasil, Bolsa, Balcão – B3) and the market as follows:

Cemig has subscribed to the Tax Credits Regularization Plan (Plano de Regularização de Créditos Tributários, or PRCT) of Minas Gerais State, in relation to ICMS tax totaling R$588 million, resulting in a significant mitigation of risk.

The commitment by Cemig D, for an amount of R$558 million, results in a reduction of 90% in interest charged and penalty fines imposed in relation to payment of the tax. This amount is for the base-date September 2017, and will be updated by application of 50% of the Selic rate until the date of payment, which is to be made in six monthly installments. The first of these, of R$93 million, was paid on October 31, 2017.

The commitment by Cemig GT, for an amount of R$30 million, which was paid in full on October 31, 2017, reduced interest and penalty fines charged by 95%.

The decision will result in negative effects in the results for 3Q17 – reducing Ebitda by approximately R$588 million, and Net profit by approximately R$388 million.

Payment of the obligation will be financed by operational cash flow, without causing any increase in debt, and without significant change in our financial programming.

Belo Horizonte, November 9, 2017.

Trading volume in Cemig’s preferred shares (CMIG4) totaled R$ 12.94 billion in the first nine months of 2017, a daily average of R$ 69.19 million. Adding the volume traded in its common (ON) and preferred (PN) shares, Cemig was the company with the highest stock trading liquidity in the Brazilian electricity sector in the period, and among the most traded in the Brazilian market as a whole.

On the New York Stock Exchange the volume traded in ADRs for Cemig’s preferred shares (CIG) in first nine months of 2017 was US$ 2.46 billion: we see this as reflecting recognition by the investor market – and as maintaining Cemig’s undeniable status as a global investment option.

The electricity market of Cemig D

Electricity billed to captive clients by Cemig D, and electricity transported for Free Clients and distributors with access to Cemig D’s networks, totaled 10,826 GWh in 3Q17, or 0.27% more than in 3Q16.

There are two components of this reduction: consumption by the captive market 2.1% lower YoY, and use of the network by Free Clients 3.7% higher YoY.

In September 2017 the Cemig D invoiced 8,323,807 clients – a growth of 1.2% in the consumer base since the end of September 2016.

Comments on the various consumer categories:

Residential

Consumption by captive residential users of Cemig D in 3Q17, at 2,456,908 MWh, was 2.83% more than in 3Q16. The higher residential consumption can be seen as reflecting: the addition of 89,316 new consumer units; higher temperatures in 3Q17, causing more use of air conditioners and ventilators in homes; and economic indicators of income and employment showing signs of recovery.

Industrial

Electricity used by captive industrial clients of Cemig D totaled 649,318 MWh in 3Q17 – a reduction of 17.91% when compared to 3Q16.

56

This lower consumption mainly reflects migration of captive consumers to the Free Market – which was also responsible for part of the increase in the total volume of power distributed.

Cemig D transported a total of 4,585,830 MWh for Free Clients in 3Q17.

Commercial

Total consumption by the captive clients of Cemig D in the commercial category totaled 1,207,847 MWh, or 7.32% less than in 3Q16, mainly because of the adverse conditions of the economy, with lower disposable family incomes and lower economic activity in the other private and public sectors of the economy.

Cemig D transported a total of 239,256 MWh for industrial Free Clients in 3Q17. The 59.30% positive YoY comparison of volume transported for Free Clients mainly reflects incorporation of new facilities supplied with power from incentive-bearing sources.

The electricity market of Cemig GT

Cemig GT billed a total of 7,399,204 MWh in 2016, 1.62% more than in 3Q16.

The number of clients billed by Cemig GT was 28.8% higher than in September 2016, totaling 1,203. Of these: 1,137 were industrial, commercial and rural clients; 47 were distribution companies; and 20 were companies in the category of traders, generators and independent power producers. From the end of September 2016 to the end of September 2017 Cemig GT added 102 new industrial clients, 1 rural client and 174 clients in the Commercial and Services category.

57

Free Clients in the industrial, commercial and rural categories consumed 3,951,230 MWh in 3Q17, or 7.1% less than in 3Q16.

This lower amount reflects consumption by industrial clients 16.1% lower year-on-year, due to: some industrial clients terminating contracts with Cemig GT and signing new contracts with Cemig subsidiary companies; and low consumption of industrial clients due to the economic context in Brazil.

Trading of electricity to other agents in the electricity sector in the Free Market totaled 2,856,740 MWh in 3Q17, 17.1% less than in 3Q16.

CVA and Other financial components in tariff adjustment

In its interim accounting information Cemig recognizes the difference between actual non-controllable costs (in which the CDE, and electricity bought for resale, are significant components) and the costs that were used as the basis of decision of the rates charged to consumers. This balance is the amount that will be passed through to the Company, or reimbursed to the consumer through Cemig D’s next subsequent tariff adjustments. In 3Q17 amounts totaling R$ 480,112 to be passed through to the Company in the next tariff adjustment were recognized, compared to a negative balance (i.e. to be reimbursed) of R$ 273,498 arising in 3Q16.

This variation is mainly due to the higher costs of electricity in 3Q17, producing a larger difference between the amounts spent and the costs recognized in the tariff. The variations found are the subject of monetary updating based on the Selic rate and compensated in the subsequent tariff adjustments.

(1) | Due to unfavorable hydrological conditions since July 2017, there has been less hydroelectric generation and as a result more dispatching of thermal plants, increasing the spot price (PLD), and affecting the level of reduction of the physical power offtake guarantee of the hydroelectric plants. For the distributors, this results in higher costs of CCEAR contracts, with thermal plants, and higher hydrological risk costs for the Itaipu plant, for those that trade power supply under Physical Guarantee Quotas, and for those that sold CCEARs and renegotiated the Hydrological Risk. In view of these factors, the difference from the cost taken into account in setting the tariff if greater, resulting in an increase in the deferred asset related to purchase of power supply on September 30, 2017.

(2) | Billing arising from the Flag Tariff System not yet homologated by Aneel.

(3) | In accordance with the rules of Proret 2.1A, from this point onward amounts of excess of demand and excess of reactive power were appropriated to sector financial liabilities, and will be amortized only at the time of homologation of the 5th periodic tariff review cycle.

Transmission indemnity revenue

Transmission indemnity revenue in 3Q17 was R$ 25,894, compared to R$ 99,742 in 3Q16.

In 2Q16, as a result of the Mining and Energy Ministry setting the criteria for updating of the transmission indemnity, a posting was made, backdated to 2013, of the amount of the updating of the indemnity receivable based on the regulatory cost of own capital, and this had a significant impact on the revenue reported.

On April 10, 2017, an interim court remedy was granted to the Brazilian Large-scale Free Consumers Association (Associação Brasileira de Grandes Consumidores Livres), the Brazilian Auto Glass Industry Technical Association (Associação Técnica Brasileira das Indústrias Automáticas de Vidro) and the Brazilian Ferro-alloys and Silicon Metal Producers’ Association (Associação Brasileira dos Produtores de Ferroligas e de Silicio Metálico) in their legal action against Aneel and the federal government requesting suspension of the effects on their tariffs of payment of the indemnity for transmission assets payable to agents of the electricity sector who accepted the terms of Law 12783/2013.

The preventive remedy was partial, with effects related to suspension of the inclusion in the consumer tariffs paid by these associations of the portion of the indemnity corresponding to the remuneration on capital included since the date of extension of the concessions.

Cemig GT has the expectation of realization in full of the credits receivable in relation to the transmission indemnity, and has calculated the following amounts as indemnity:

|  | R$ ’000 |
Regulatory Remuneration Base (BRR) – Dispatch 2181/2016 |  |  | 1,177,488 |
Amount of the indemnity received so far |  |  | (285,438 | )

Normative Resolution 762, of February 21, 2017, set the procedures and criteria to be used in the calculation of the cost of capital to be added to the Permitted Annual Revenue of each transmission concession holder covered by Law 12783/2013, in harmony with Mining and Energy Ministry Order 120/2016. Under this legislation, the Company began to receive this indemnity as from July, 2017.

Generation Indemnity Revenue

In 3Q17 the Company recognized revenue of R$ 259,516 for the adjustment to the balance not yet amortized of the concessions for the São Simão and Miranda Hydroelectric Plants, as per Ministerial Order 291/17.

On August 3, 2017, the Mining and Energy Ministry published Ministerial Order 291, setting the amounts of indemnity for the São Simão and Miranda Plants.

The Order specifies that the payment shall be made by December 31, 2018, after receipt of the payment of the Concession Grant Fee, for acquisition of the concession, resulting from the competitive tender that was held for the concessions of the plants. The amount of the indemnity will be updated by the IPCA (Amplified Consumer Price) index, up to the date of the signature of the Concession Contract by the party that won the tender for the concession of the Plants, and also by the Selic Reference Rate for Federal securities, as from the date of signature of the Concession Contract up to the date of actual payment of the indemnity.

Cemig GT is holding talks with the Mining and Energy Ministry on the criteria used for the decision on the amounts stated in Ministerial Order 291/17, and also the fact that this Order did not take into consideration the un-amortized balance of the Jaguara Plant in the amount of R$ 169,822, and the balances of investments carried out to the São Simão and Miranda Plants after their coming into operation, in the amounts (before monetary updating) of R$ 3,243 and R$ 22,546, respectively.

The amounts of the Basic Plan of the plants were transferred to the account Indemnity receivable, and subjected to monetary updating, as follows:

Plant |  | Concession termination date |  |  | Net balance of assets based on Historic Cost at September 30, 2017 |  |  | Net value of assets based on Deemed Cost at September 30, 2017 |  |  | Net value of the assets of the Basic Plan based on Deemed Cost at September 30, 2017 |  |  | Adjustment (1) |  |  | Amounts in MME Order |  |  | Monetary updating |  |  | Net balance of the assets of the Basic Plan at Sep. 30, 2017 |

Revenue from transactions in the Wholesale Trading Market (CCEE)

Revenue from transactions in electricity on the CCEE in 3Q17 was R$ 111,330, compared to R$ 87,198 in 3Q16 – or 27.67% higher YoY. This basically reflects the average spot price (‘PLD’) being 278.14% higher – at R$ 436.19/MWh in 3Q17, compared to R$ 115.35/MWh in the same period of 2016.

Revenue from supply of gas

The Company reported revenue from supply of gas 42.65% higher year-on-year in 3Q17, at R$ 484,491, compared to R$ 339,634 in 3Q16, mainly due to the higher volume of gas sold: 375,870m³ in 3Q17, compared to 238,440m³ in 3Q16.

There was a recovery of activity in the industrial user category, the largest in Gasmig’s market, with higher consumption by companies in the metallurgy sector.

Supply of gas to the residential market, which began in 2013, totaled 26,836 households invoiced in September 2017 – compared to 14,935 at the end of September 2016.

Sector/Regulatory charges reported as Deductions from revenue

The total of these taxes and charges reported as deductions from revenue in 3Q17 was R$ 3,181,073 – an increase of 26.74% in relation to their total of R$ 2,509,870 in 3Q16.

The Company adhered to the Minas Gerais State Tax Credits Regularization Plan (Plano de Regularização de Créditos Tributários – PRCT), for settlement of certain items of ICMS (state value added tax). The effect reported in 3Q17 was an expense on ICMS of R$ 587,629 (Cemig D and Cemig GT R$ 557,673 and R$ 29,951 respectively).

The commitment by Cemig D results in a reduction of 90% in interest charged and penalty fines imposed in relation to payment of the tax. This amount is for the base-date September 2017, and will be updated by application of 50% of the Selic rate until the date of payment, which is to be made in six monthly installments. The first of these, of R$ 93 million, was paid on October 31, 2017. This adhesion to the PRCT is related to specific amounts charged by the State for ICMS tax: on the funding the Company receives from the CDE (Energy Development Account) and at an additional rate of ICMS charged on condominiums in the ‘residential’ consumer class.

The commitment by Cemig GT, for an amount of R$ 30 million, which was paid in full on October 31, 2017, resulted in a reduction of 95% in interest and penalty fines charged on termination of deferral in the transfers of electric power from consortia to consortium members.

Consumer charges – the ‘Flag’ Tariff system

There was an increase in the Consumer Charges related to the ‘Flag’ tariff system: The figure for 3Q17 was an amount charged to the consumer of R$ 101,625, compared to a reversal in 3Q16, of R$ 429. This variation is due to the change in the tariff ‘Flag’ – it was ‘yellow’ in July, and ‘red’ in August, 2017, which compares to ‘green’ in 3Q16 – indicating implies a larger incoming amount in 3Q17.

Operational costs and expenses

Operational costs and expenses totaled R$ 5,160,438 in 3Q17, or 31.06% more than in 3Q16 (R$ 3,937,376).

The following paragraphs comment on the main variations:

65

Electricity purchased for resale

The expense on electricity bought for resale in 3Q17 was R$ 2,942,974, or 35.60% more than in 3Q16 (R$ 2,170,348). The main factors in the higher figure are:

Cemig D:

The expense on electricity bought for resale in 3Q17 was R$ 1,662,921, or 22.09% more than in 3Q16 (R$ 1,362,092).

This mainly reflects higher expenses on purchase of supply in the spot market, totaling R$ 336,398 in 3Q17, compared to R$ 191,655 in 3Q16, in turn reflecting the higher cost of supply in the wholesale market in 2017 as a result of the low level of the reservoirs, and lower output of supply by the hydroelectric plants. The result was a higher volume of operation of the thermal plants, for which the increase in expenditure was financed principally by the electricity distributors, which is a feature of the present regulatory model in Brazil.

Also, expense on purchase of electricity at auctions was higher: at R$ 835,259 in 3Q17, compared to R$ 672,294 in 3Q16 – reflecting new power purchase agreements made in the regulated market in 2017.

Cemig GT:

The expense on electricity bought for resale in 3Q17 was R$ 1,275,814, or 54.91% more than in 3Q16 (R$ 823,584). This reflects an average price per MWh 15.84% higher in 3Q17 (R$ 186.60 in 2017, vs. R$ 161.39 in 2016), and also a volume of electricity purchased in 3Q17 (at 6,823,933 MWh) 33.72% higher than in 3Q16 (5,103,045 MWh).

66

Operating provisions

Operational provisions were R$ 188,875 in 3Q17, compared to a reversal of provisions totaling R$ 19,375 in 3Q16. The main factors are:

| ◾ | Reversal of provision on the investment options related to RME and LEPSA, in the total amount of R$ 166,767, in 3Q16, which compares with provisions of R$ 85,306 made in 3Q17.

| ◾ | Lower provisions for doubtful receivables: R$ 50,458 in 3Q17, compared to R$ 108,349 in 3Q16 – mainly reflecting lower default.

|  |  | 1,502,473 |  |  |  | 1,341,468 |

Default

With the effects of the Brazilian macroeconomic context of reduction in economic activity, bringing unemployment and inflation, the adverse hydrological situation, and the increase in tariffs, which had been held down, Cemig has experienced higher than average growth in the total debt owed by clients.

To combat a record level of default, in 2017 Cemig has redoubled its efforts to receive payment from customers in arrears with their electricity bills. An additional budget has been approved and is being used this year in the attempt to recover the previous losses of revenue. Some results have already been achieved. Since December 2016 there has been no significant increase in the default percentages, showing that this situation is being brought under control. We expect to see a more consistent decline in the percentages from now on.

The average level of default increased by 3.36% from September 2016 to September 2017; but the percentage has fallen by 1.60% since September 2017.

67

The Company uses various tools of communication and collection to prevent increase in default. Measures used include contact by telephone, email, collection requests by text and by letter, negative references for defaulting clients, collection through the courts and, principally, disconnection of supply. Aneel Resolution 414 allows supply to be cut off after 15 days from receipt of a notice to the defaulting consumer.

As well as these various collection tools, in 2017 Cemig launched a campaign offering special conditions for negotiation and re-negotiation for low-voltage consumers, hospitals and public authorities.

The Company is confident that with more intense collection and disconnection the levels of default will be reduced in 2017.

Personnel

The expense on personnel in 3Q17 was R$ 358,505, or 4.14% lower than in 3Q16 (R$ 373,986).

Gas bought for resale

In 3Q17 the Company recorded an expense of R$ 304,698 on acquisition of gas, 55.07% higher than its comparable expense of R$ 196,494 in 3Q16. This basically reflects the higher volume of gas acquired (385,487m³ in 3Q17 compared to 234,926m³ in 3Q16).

68

Equity method gains in non-consolidated investees

In 3Q17 Cemig posted a net equity method loss of R$ 80,798, which compares with a net gain of R$ 33,218 in 3Q16. This principally arises from: the losses by the equity method on Renova and the Santo Antônio and Belo Monte plants.

Financial revenue and expenses

Cemig reported net financial revenues in 3Q17 of R$ 12,414, which compares with net financial expenses of R$ 422,912 in 3Q16. The main factors are:

| ◾ | A negative balance of R$ 12,006 in monetary updating of the CVA balances in 3Q17, compared to a gain of R$ 19,403 in 3Q16. The positive and negative balances of CVA are updated by the Selic rate. This difference arises from a net payable amount of CVA on September 30, 2017. In 3Q16 the corresponding amount was a credit.

| ◾ | Income from cash investments was R$ 38,718 lower, due mainly to a lower volume of cash invested.

| ◾ | The financial expense on monetary updating of loans and financings was R$ 41,277 lower, due to the lower total effect of the IPCA inflation index (indexor for the debt) in the quarter – 0.59% in 3Q17, compared to 1.04% in 3Q16.

| ◾ | Costs of loans and financing was 34.39% lower, at R$ 344,297 in 3Q17, compared to R$ 524,775 in 3Q16, due to the lower CDI rate (principal indexor of the debt) over the period – of 2.29% in 3Q17, compared to 3.47% in 3Q16.

| ◾ | Reversal of the monetary updating item of R$ 239,445 applied by the Minas Gerais state government for its Advance against future capital increase (AFAC). On October 25, 2017, Cemig and the Financial Department of Minas Gerais State signed a Debt Recognition Undertaking, under which the State undertook to return to the company the total amount deposited, with monetary updating by the IGP-M inflation index. As a result of the new situation the probability of loss was re-assessed to ‘remote’, due to there no longer being any expectation of future disbursement of cash to settle this obligation, which had until then been provisioned. The Debt Recognition Undertaking signed between the parties specifies that the State will return the amount of R$ 277,723, of which R$ 239,445 refers to the original amount of the deposit, and R$ 38,278 relates to its monetary updating to September 30, 2017. This amount will be returned to the Company by the State in 12 consecutive monthly installments, each updated by the IGP–M index up to the date of actual payment, the first such payment to become due on November 10, 2017. Additionally, Clause 3 of the Undertaking states that, in the event of arrears or default by the State in payment of the agreed consecutive monthly installments, Cemig is authorized to retain dividends or Interest on Equity distributable to the State in proportion to the State’s equity interest, for as long as the arrears and/or default continues.
