Management of VCP and Aracruz further inform that, in compliance with Law 6,404/76, Special Meetings of Preferred Shareholders (Assembleia Especial de Titulares de Ações Preferenciais) for each of the companies have also been called, so that preferred shareholders of VCP may vote on the conversion of VCP preferred shares into VCP common shares, and preferred shareholders of Aracruz may vote on the conversion of Aracruz Class A preferred shares and Class B preferred shares into Aracruz common shares.

The ratio of conversion of VCP preferred shares into VCP common shares and of Aracruz preferred shares into Aracruz common shares will be, in each case, one preferred share for 0.91 common share of each company, respectively.
