► We show above the conciliation between CEMAR’s EBITDA as reported in the previous quarters (according to BR GAAP),
and the EBITDA reported in 4Q10. Basically, two differences should be noted:
► Regulatory Assets and Liabilities: By the IFRS standards, regulatory assets and liabilities should not be accounted, not
affecting the quarterly EBITDA and, consequently, there should be no more asset or liability in the Balance Sheet.
► Profit Sharing: This expense was transferred from a specific line above the Net Income, to the Personnel in the PMSO,
negatively affecting the company’s EBITDA.

► REFIS’ Adherence: In the 4Q09, R$24.5 million were excluded from the EBITDA due to fine reduction in CEMAR’s adherence
to REFIS.
► Judicial Deposits: In the 4Q10, we did not consider R$15.0 million in expenses arising from updating CEMAR’s judicial
deposit balance made in previous years.
► Thus, Equatorial’s EBITDA on a recurring basis grew 15.6% in 4Q10.

CEMAR.

reduced Equatorial’s Net Income by R$14.5 million.
