F-Secure's Board of Directors has decided to start repurchase of its own shares 
based on the authorization of the Annual General Meeting of March 26, 2008. The 
maximum amount to be repurchased is 2.500.000 shares, representing 1.6% of all  
the shares issued by the Company. F-Secure currently holds no own shares.       
The shares are purchased through public trading on the OMX Helsinki in          
accordance with its rules and at market price.  
                                
The own shares will be purchased to be used for making acquisitions or          
implementing other arrangements related to the Company's business, to improve   
the Company's financial structure, to be used as part of the incentive          
compensation plan or for the purpose of otherwise assigning or cancelling the   
shares. 
                                                                        
The repurchase of own shares will commence on November 4, 2008, at the earliest.
