A FLAGGING NOTIFICATION REFERRED TO IN CHAPTER 2, SECTION 9 OF THE SECURITIES   
MARKETS ACT ON A CHANGE IN HOLDINGS                                             

This is a notification about Exista's divest of shares in Sampo in order to     
maintain Exista's 19.98 per cent shareholding unchanged, following decided      
cancellation of shares in Sampo Plc.                                            

As a result of transactions entered into by Exista hf.'s group companies and the
cancellation of Sampo Plc.'s trasury shares, Exista hf.'s combined current and  
future holdings in Sampo Plc. fall below 20 per cent of the shares of Sampo Plc.
but the current holdings remain at the previous level of 19.98 per cent of the  
total number of shares and 19.82 per cent. of the voting rights. These          
transactions have been carried out to maintain the holdings at the level        
authorised by the relevant regulatory authorities, including the Finnish        
Insurance Supervision Authority.

2. Reason for the notification

- Sampo Plc. has on 7 May 2008 decided to cancel a total of 6,715,000 of its    
treasury A shares, but the cancellation has not been registered at the date of  
this notification;                                                              

- Exista B.V., Exista Trading ehf. and Vátryggingafélag Íslands hf.  have       
divested a total of 1,350,000 A shares in Sampo Plc.; and                       

- Exista Trading ehf. has cancelled the equity swap agreement regarding 100,000 
A shares in Sampo Plc referred to in Exista hf.'s flagging notification of 11

Therefore, the combined current and future holdings of Exista hf.'s group       
companies fall below 20 per cent of the shares of Sampo Plc., but the current   
holdings remain at 19.98 per cent of the total number of shares and 19.82 per   
cent of the voting rights in the Sampo Plc, which is the previous level of      
holdings approved by the relevant regulatory authorities, including the Finnish

3. Date of the transactions
