No. The hiring of financial advisory services for this purpose is not mandatory, and the registration update must be requested directly by the debenture holder to Banco Bradesco, the Company's bookkeeping agent, which will inform the procedure to be followed for the update. In general, to request the regularization of registration data, the debenture holder must look for a branch of Banco Bradesco S.A., the bookkeeping agent for Vale's equity debentures, with personal identification documents (RG, CPF and Proof of Residence), as well as a proof of bank domicile. Further guidance can be obtained by calling 0800-701-1616 (Investor Guidance Channel). Alternatively, investors can also contact Vale's Investor Relations department via e-mail at vale.ri@vale.com. There is no charge by Bradesco or Vale for providing information on equity debentures or for updating the registration.
