(a)

The Company adhered to PROUNI, established by Law 11,096 / 2005, which is a federal program that exempt companies of paying income taxes and social contribution.

(b)

Brazilian tax law establishes that companies that generate gross revenues of up to R$ 78,000 in the prior fiscal year may calculate income taxes as a percentage of gross revenue, using the presumed profit income tax regime. The effect of the presumed profit of certain subsidiaries represents the difference between the taxation based on this method and the amount that would be due based on the statutory rate applied to the taxable profit of the subsidiaries.
