Furthermore, YIT Corporation has applied for the listing of an additional lot of
the company's shares on the OMX Nordic Exchange in Helsinki. The application    
concerns the new shares subscribed for with the Series K, L and M share options 
in 2008.                                                                        

Share subscriptions                                                             

Each Series K, L and M share option entitles its holder to subscribe for one YIT
Corporation share (YTY1V).

options, max 900,000 shares with Series L share options and max 900,000 shares  
with Series M share options.                                                    

The subscription price of a share subscribed for with either Series K or L share
options is EUR 20.53 per share. The subscription price of a share subscribed for
with the Series M share options is EUR 19.73 per share given that the Annual    
General Meeting decides that dividend per share is EUR 0.80.

Trade Register.
