m) Purchases of shares/quotas of Termobahia
On April 3, 2008, Petrobras concluded the transaction for acquisition, for R$ 9.363, of all the shares issued by Termobahia S.A., held by Blade Securities Limited.
Blade is a specific purpose entity with its headquarters in Ireland, which, through project financing agreed upon with the Interamerican Development Bank (IDB), held a stake in Termobahia.
With the pre-payment to IBD all the obligations and restrictions arrising from this financing ceased, thus eliminating the barrier to Petrobras increasing its shareholding interest in Termobahia.
