► The financial information contained herein is presented in consolidated figures, pursuant to Brazilian

Corporate Law, based on revised financial information.

► Consolidated financial information represents 100% of CEMAR’s results and 25% of Light’s results.

► Consolidated operating information represents 100% of both CEMAR´s and Light’s results.

► In order to facilitate comparisons with the 2Q07 and the 1H07, the financial information is presented on a

pro-forma basis considering the same interest currently held by Equatorial in RME (25.0%) and by RME

4Q07. In addition, Light’s pro-forma result includes the adjustments related to Law 11,638, determined by

CVM Instruction 469/08.
