1. CORPORATE DECISIONS


The First Issue of
Commercial Promissory Notes (“the Offering”, “the Issue”, and “the Securities”)
was approved by the Board of Directors of Cemig Geração e Transmissão S.A. (“Cemig GT”, the “Issuer” or “the
Company”) at a meeting held on June 29, 2006.











2. INFORMATION ABOUT THE ISSUE


2.1. Total amount of the Issue


The total amount of the issue is R$ 900,000,000.00
(nine hundred million Reais).


2.2. Quantity of Securities


The issue is made up of 90 (ninety) Commercial Paper
Securities (Promissory Notes).


2.3. Nominal unit value


The par value (“the Nominal Unit Value”) of the
Securities is R$ 10,000,000.00 (ten million Reais).


2.4.  Series


The Securities will be issued in a single series.


2.5. Remuneration


Remuneration interest shall be due, at the rate of
103% (one hundred and three per cent) of the average daily rate for interbank
deposits known as the “DI over extra-grupo Rate”,
on the Nominal Unit Value, expressed in the form of an annual rate in per cent,
on the 252 (two-hundred-and-fifty-two)-business-day, calculated and published
daily by the CETIP (Custody and Settlement Chamber) in its daily bulletin
available on its Internet page (http://www.cetip.com.br) (“The DI Rate” and “the
Remuneration”). The Remuneration shall be calculated exponentially and
cumulatively pro rata tempore per business
day, applicable to the Nominal Unit Value from the date of the actual
subscription and paying-up (“Issue Date”) of the Securities up to the Maturity
Date, in accordance with the following formula:


J = VNe x (InterestFactor – 1),











Where:


J =                             unit
value of the remuneration interest, calculated to 6 (six) decimal places,
without rounding, payable at the end of the Capitalization Period.


VNe
=             the Nominal Value of
the issue, published/calculated to 6 (six) decimal places, without rounding.


InterestFactor  =  product of the DI Rates, summed
exponentially with a percentage factor, from the start date of the
Capitalization Period, inclusive, up to the date of termination of
Capitalization Period exclusive, calculated to 8 (eight) decimal places,
without rounding, as found by the following formula:





Where:


n =                           the
total number of days of the DI Rate used in the updating of the asset, where “n”
is a whole number.


P =                             103%
(percentage applied to the DI Rate).


TDIk
=         the DI Rate, expressed by
day, calculated to 8 (eight) decimal places, with rounding, as follows:





Where:


DIk
=                 The
DI Rate published by CETIP, valid for 1 (one) business day (“overnight”), used
to 2 (two) decimal places.


“Capitalization
Period”:                   This
is the time interval starting on the Issue Date, inclusive, and ending on the
date of payment of the Nominal Unit Value of the Security, exclusive, plus the
Remuneration.


If at any time during the
period of validity of the Securities the DI Rate is not published, the last
previous available DI Rate shall be applied, and in this event no offsetting between
the Issuer and the holders of the Securities shall be payable when the DI Rate
that would be applicable is subsequently published.











If the DI Rate
ceases to be published for a period of more than 10 (ten) days, or if it is
abolished or if there is a legal 
impossibility of application of the DI Rate to the Securities, the legal
parameter which is established, if any, shall be used in substitution of it. If
there is not a substitute legal parameter for the DI Rate, then the weighted
average rate of remuneration of Brazilian short-term federal public securities
with maturity of 90 (ninety) days traded in the prior 30 (thirty) days, at the
time of the occurrence, shall be used.


2.6. Date of Issue and form of paying-up


For all intents and purposes, the Date of Issue of the
securities shall be the date of their actual subscription and paying-up (“the
Issue Date”). The securities shall be subscribed for Nominal Unit Value, in
Brazilian currency, at sight, on the date of subscription


2.7. Subscription Price


The securities shall be subscribed for their Nominal
Unit Value (“the Subscription Price”).


2.8. Period of subscription and paying-up


The Securities must be subscribed and paid-up within 8
(eight) business days from the date of publication of this Announcement of
Commencement of Distribution of Commercial Paper Securities (“the Commencement Announcement”), subject to the
provisions of item 4.2 below.


2.9. Form


The Security shall be nominal,
and issued in physical form, and shall be held on deposit with an institution
qualified to provide the services of custody. The Securities shall be nominal
and shall be transferred by nominal endorsement, resulting in simple transfer
of ownership.











2.10. Guarantee


The Securities are guaranteed by a guarantee given by
Companhia Energética de Minas Gerais – Cemig (“Cemig”, or “the Guarantor”).


The Lead Manager warrants that the guarantee by CEMIG
was duly constituted by signature of its legal representatives on the reverse
side of the physical issued form of each of the Securities, guaranteeing the
totality of the debt represented by them, and the guarantee in question was
duly approved by a meeting of the Board of Directors of CEMIG held on June 29,
2006, and is, thus, fully enforceable against CEMIG.
