The holders of ADR have equivalent rights to the holders of ordinary shares. The voting rights of the holders of ADS are calculated considering that each ADR represents 10 ordinary shares. The holders of ADR may instruct the depositary bank to exercise their voting rights or give that power to a representative designated by EDP to that purpose, according to the applicable legal and statutory dispositions; the deposit contract regulates the timing and fashion for the exercise of voting instructions, as well as the absence of instructions.
