ANNUAL GENERAL MEETING OF SHAREHOLDERS

This report contains the registrant’s notice and agenda for its Annual General Meeting of Shareholders to be held on April 18, 2012, together with a copy of the form of proxy to be solicited by the registrant.

The attachment contains forward-looking statements. The registrant desires to qualify for the “safe-harbor” provisions of the Private Securities Litigation Reform Act of 1995, and consequently is hereby filing cautionary statements identifying important factors that could cause the registrant’s actual results to differ materially from those set forth in the attachment.

The registrant’s forward-looking statements are based on the registrant’s current expectations, assumptions, estimates and projections about the registrant and its industry. These forward-looking statements can be identified by words or phrases such as “anticipate,” “believe,” “continue,” “estimate,” “expect,” “intend,” “is/are likely to,” “may,” “plan,” “should,” “would,” or other similar expressions.

The forward-looking statements included in the attached relate to, among others: (i) the registrant’s business prospects and future results of operations; (ii) weather and other natural phenomena; (iii) developments in, or changes to, the laws, regulations and governmental policies governing the registrant’s business, including limitations on ownership of farmland by foreign entities in certain jurisdictions in which the registrant operate, environmental laws and regulations; (iv) the implementation of the registrant’s business strategy, including its development of the Ivinhema mill and other current projects; (v) the registrant’s plans relating to acquisitions, joint ventures, strategic alliances or divestitures; (vi) the implementation of the registrant’s financing strategy and capital expenditure plan; (vii) the maintenance of the registrant’s relationships with customers; (viii) the competitive nature of the industries in which the registrant operates; (ix) the cost and availability of financing; (x) future demand for the commodities the registrant produces; (xi) international prices for commodities; (xii) the condition of the registrant’s land holdings; (xiii) the development of the logistics and infrastructure for transportation of the registrant’s products in the countries where it operates; (xiv) the performance of the South American and world economies; and (xv) the relative value of the Brazilian Real, the Argentine Peso, and the Uruguayan Peso compared to other currencies; as well as other risks included in the registrant’s other filings and submissions with the United States Securities and Exchange Commission.

These forward-looking statements involve various risks and uncertainties. Although the registrant believes that its expectations expressed in these forward-looking statements are reasonable, its expectations may turn out to be incorrect. The registrant’s actual results could be materially different from its expectations. In light of the risks and uncertainties described above, the estimates and forward-looking statements discussed in the attached might not occur, and the registrant’s future results and its performance may differ materially from those expressed in these forward-looking statements due to, inclusive, but not limited to, the factors mentioned above. Because of these uncertainties, you should not make any investment decision based on these estimates and forward-looking statements.

The forward-looking statements made in the attached relate only to events or information as of the date on which the statements are made in the attached. The registrant undertakes no obligation to update any forward-looking statements to reflect events or circumstances after the date on which the statements are made or to reflect the occurrence of unanticipated events.
