APPENDIX II  CONDITIONS FOR EXTENSION  EFFICIENCY IN PROVISION OF DISTRIBUTION SERVICE  CEMIG
DISTRIBUIÇÃO S.A.

CLAUSE ONE  CONTINUITY OF SUPPLY

The Criterion of Efficiency in relation to the Quality of Service Provided shall be measured by Indicators that consider the frequency and average duration of
outages in Public Electricity Distribution Service.

Subclause One The following two indicators shall be evaluated: DECi  Average
Duration of Outages of Internal Origin per Consumer Unit; and FECi  Average Frequency of Outages of Internal Original per Consumer Unit.

Subclause Two The indicators DECi and FECi correspond to the Portion with Origin Internal to the Distribution System of the Outages that are
considered for the Calculation of the indicators DEC and FEC defined in Aneel Regulations, in accordance with the following equations:

DECi = DECip + DECind

FECi = FECip + FECind

Where:

Deci = Average Duration of Outages of Internal Origin per Consumer Unit.

DECip = DEC due to Outages with Origin Internal to the Distribution System that are Programmed, not
taking place on a Critical Day, as defined in Aneel Regulations.

DECind= DEC due to Outages of
Origin Internal to the Distribution System, not Programmed, and not Purgeable, as defined in Aneel Regulations.

FECi= Average Frequency of Outages of Internal Origin per consumer unit.

FECip= FEC due to Outages of Origin Internal to the Distribution System, Programmed, and not occurring on a Critical Day, as defined in Aneel Regulations.

FECind= FEC due to Outage of Original Internal to the Distribution System, not Programmed, and Not
Purgeable, as defined in Aneel Regulations.

Subclause Three The total annual limits for the indicators DECi and FECi to be complied with by DISTRIBUTOR are presented in the following Table I:
