 EXHIBIT INDEX

Exhibit 99.1

This business combination involves the securities of aBrazilian company. The business combination is subject to disclosure requirements of Brazil that are different from those of the UnitedStates. Financial statements included in the document, if any, have been prepared in accordance with foreign accounting standards thatmay not be comparable to financial statements of United States companies.

It may be difficult for you to enforce your rights andany claim you may have arising under the U.S. federal securities laws, since the issuer is located in Brazil, and some or all of its officersand directors may be residents of Brazil. You may not be able to sue a Brazilian company or its officers or directors in a Brazilian courtfor violations of the U.S. securities laws. It may be difficult to compel a Brazilian company and its affiliates to subject themselvesto a U.S. court’s judgment.

You should be aware that the issuer may purchase securitiesotherwise than under the exchange offer, such as in open market or privately negotiated purchases.
