São Paulo, November 4, 2011 - Trisul S.A.

1. As widely disclosed to the market through the material fact notices published on August 15th and 29th, September 8th and October 13th 2011, during the second quarter of the year, the Company carried out the budget review of its works in progress this year.

2. This review hampered the conclusion of independent audit in time for the disclosure of the Interim Accounting Information (ITR) relating to the second quarter of 2011.

3. Nevertheless, the Company wishes to point out that the reasons for the delay were in no way caused or influenced by acts commission or omission on the part of any member of the Board, including Messrs. Marco Antônio Cattini Mattar and Lincoln Carvalho de Castro, who, during their leadership of their respective departments, performed their functions with the highest level of resolve and diligence.

4. Their exit from the Company’s management is solely on account of the restructuring being conducted by the Board in light of the decrease in real estate launches expected this year.

5. Thus, the exit of Messrs. Marco Antônio Cattini Mattar and Lincoln Carvalho de Castro is in no way related to the delay in the disclosure of the financial statements relating to the second quarter of 2011. In fact, the Company continues to count on the support of Mr. Marco Mattar in its Board of Directors and expects to also count on the expertise and experience of Mr. Lincoln Castro in advising the management.
