CIRCULAR LETTER/CVM/SEP/No. 004/2012

Rio de Janeiro, July 26, 2012.

SUBJECT: New version of the Empresas.net program – Version 5.1

Dear Director of Investor Relations/Legal Representative,

This Circular Letter serves to inform publicly held and foreign companies that, effective immediately, a new version of the Empresas.Net System (version 5.1) will be available, bringing the following improvements: (a) adjustment to the routine for utilizing data from previously submitted ITR and DFP forms; and (b) adjustments to the configuration of the FRE form database.

Until 08/03/2012, documents generated by both version 5.0 and version 5.1 will be accepted. After this date, only documents sent via version 5.1 will be accepted.

The new version of the System can be downloaded from the CVM's electronic page on the World Wide Web (http://www.cvm.gov.br, MARKET PARTICIPANTS section, DOCUMENT SUBMISSION item, EMPRESAS.NET subitem), as well as from the BM&FBOVESPA page (http://www.bmfbovespa.com.br, MARKET - SHARES section, COMPANIES item, FOR COMPANIES subitem, For Listed Cos subitem, EMPRESAS.NET System subitem).

The Empresas.Net 5.1 program can only be installed on computers following the IBM (PC) standard and having Microsoft .Net Framework 4 or higher installed, along with the Windows XP Service Pack 3 or Windows Server 2003 Service Pack 2 or Windows Vista Service Pack 1 or higher or Windows 7 Service Pack 1 operating system in 32 or 64-bit architecture. A Pentium processor of 1ghz or equivalent, 1 GB of RAM memory, and 2 GB of free hard disk space are recommended.

Before installing version 5.1, a backup of the existing forms in the previous system version must be performed, especially those not yet delivered, using the "Backup" function. After installing the new version, to recover files, if necessary, the "Import" function must be used.

It is not necessary to resubmit forms already delivered by the previous version solely due to this new version 5.1.

We remind you that the documents to be sent via the Empresas.Net System (Reference Forms, DFP, and ITR) must be related to an updated and current-year version of the Cadastral Form. Therefore, the computer used for sending forms must contain this updated version of the Cadastral Form, which can be obtained by downloading the last version sent, from the CVM or BM&FBOVESPA websites, or generated by the company.

Sincerely,

JORGE LUÍS DA ROCHA ANDRADE
Superintendent of Corporate Relations
