Stock Split

Rio de Janeiro, December 04, 2012

Transmissora Aliança de Energia Elétrica S.A. ("Company") informs its shareholders, the market in general and other stakeholders that at the Company’s Extraordinary Shareholders’ Meeting held on this date, the Company’s stock split has been approved, so that each common or preferred stock, represented or not by stock certificate deposits ("Units"), will be split into three (3) new shares of same class and automatically grouped into Units those stocks resulting from the split of stocks represented by Units, keeping the ratio of one (1) common stock and two (2) preferred stocks per Unit. In view of the stock split, the Company’s share capital then will be represented by 1,033,496,721 stocks, 691,553,133 common stocks and 341,943,588 preferred stocks, without changing the share capital.

In order to carry out the Company’s stock split, the depositary financial institution, Itaú Corretora de Valores S.A., will take all the measures to automatically distribute new stocks in the account of the Company’s shareholders, according to the following schedule:

(a) for registered shareholders until December 4, 2012, inclusive, each Company stock will be split into three (3) stocks, i.e., for each stock held, shareholder will receive two (2) new stocks, thus then holding three (3) stocks;

(b) as of December 5, 2012, stocks and Units will be traded but not entitled to split; and,

(c) on December 10, 2012, the Depositary Financial Institution will credit the stocks resulting from referred split.

The stock split proposal aims at increasing the liquidity of Units issued by the Company on the market. Thus, the Company expects (i) to spur the entry of new shareholders; (ii) increase the Company’s visibility towards domestic and foreign investors; and (iii) to be more compliant with the market’s best practices..
