i) Acquisition of the shares of Termobahia
On April 03, 2008, Petrobras concluded the transaction to purchase all of the shares of Termobahia S.A. held by Blade Securities Limited for R$ 9.363 thousand.
Blade is a special purpose company, which has its registered offices in Ireland and that by means of a financing agreement with the Inter-American Development Bank (IDB), held an interest in Termobahia.
With the early repayment to the IDB, all the obligations and restrictions deriving from this financing agreement ceased, thus eliminating the impediment to increase Petrobras shareholding in Termobahia.
