Petrobras (PBR)

ERRATA

We would like to inform that the item 5.6 of the Tender Offer´s invitation (“Edital”) for the acquisition of common and preferred shares of Suzano Petroquímica S.A., published herein on May 12, 2008 shall be read and construed as follows:

5.6  Final  Format: After the consolidation of the assets mentioned in item 5.5 above, the common shares to be issued by the company holding the assets described  above will be held in the proportion of 60% by Unipar and 40% by Petrobras.  The control of the referred company will be exercised by Unipar and  Petrobras  will  act  as a relevant minority shareholder, with several rights  as  set  forth in the Shareholders Agreement signed on November 30, 2007.

The registration of this offering by the CVM authorizes the sale of control of Suzano Petroquímica S.A. to Petróleo Brasileiro S.A. – Petrobras, pursuant to art. 29 §3 of CVM Instruction 361/02. However, it does not address the second part of the transaction, announced on 11/30/2007, which involves the consolidation of Suzano Petroquimica S.A. with the assets of Unipar- União de Indústrias Petroquímicas S.A.

As it relates to the second part of the above mentioned transaction, the Superintendent of the Registration of Securities at the CVM indicated, in the registration of the present offer, that it would be subject to the requirements of Article 254-A of Law 6404/76. Unipar has a different understanding and this issue will be resolved through an appeal filed on 5/7/2008.

If applicable the understanding of Superintendence of the Registration of Securities of CVM, as described above, Unipar understands that the second tender offer shall take place, obligatorily, by a price lower than the price proposed for the shares of Suzano Petroquímica S.A. in this Tender Offer. This understanding, however, is not confirmed by Superintendence of the Registration of Securities of CVM.
