TRACTEBEL ENERGIA S.A. A Publicly Listed Company - CNPJ 02.474.103/0001-19 NIRE 4230002438-4 ANNOUNCEMENT TO THE MARKET TRACTEBEL ENERGIA S.A., a publicly listed company with registered offices in the city of Florianópolis in the state of Santa Catarina at Rua Paschoal Apóstolo Pítsica, 5064, enrolled in the corporate tax register (CNPJ) under number 02.474.103/0001-19 ("Tractebel"), and pursuant to the provisions of CVM Instruction 358/2002, wishes to notify its shareholders and the market at large that through an announcement to the press ("Announcement"), published on April 16, 2012 by its indirect controlling company, GDF SUEZ S.A. ("GDF SUEZ"), the offer price to acquire the 30% stake it does not already own in International Power plc ("International Power") was revised to 418 pence sterling per share and the offer has been unanimously approved by the International Power independent board members. This amount is, therefore, higher than the 390 (three hundred and ninety) pence sterling per share offered in the Indicative Proposal announced to the market by Tractebel on March 30,

2012.
According to the GDF SUEZ, the transaction will be structured as a "Scheme of Arrangement" under the UK regulatory framework, which facilitates a shorter timetable with a targeted closing date mid-July 2012. In case of a favorable vote from International Power minority shareholders, GDF SUEZ will own 100% of International Power shares after the transaction closing.
Greater details are available in the website of GDF SUEZ: www.gdfsuez.com.
