Helsinki Court of Appeal also rejects the claims of 20 banks and brokerage firms against OMX

The Helsinki Court of Appeal issued on May 31, 2007, a decision in which it     
rejected the appeal made by twenty banks and brokerage firms against a decision 
of Helsinki District Court on June 9, 2006. Consequently, the Court rejected the
claims of those twenty banks and brokerage firms.                               

Since June 2004 OMX Exchanges Ltd and Helsinki Stock Exchange Ltd, subsidiaries 
of OMX AB, and Finnish Central Securities Depository Ltd (“APK”), were          
defendants in a lawsuit in the Helsinki District Court, and subsequently in the 
Helsinki Court of Appeal, in which twenty banks and brokerage firms together    
with two additional plaintiffs were claiming in total about EUR 5 million plus  
interest related to value added tax that the banks and brokerage firms paid to  
Helsinki Exchanges and APK for trading and clearing services in 1995-2000.      

The Helsinki District Court held in its decision that twenty of those twenty-two
banks and brokerage firms are precluded from presenting their claims because of 
an arbitration agreement concluded on March 8 and 11, 2002, by and between those
twenty banks and brokerage firms on one side and OMX Exchanges Ltd, Helsinki    
Stock Exchange Ltd. and APK on the other side. In the agreement the parties     
waived their right to present further claims outside the arbitration proceedings
related to value added tax that the banks and brokerage firms paid to Helsinki  
Exchanges and APK for trading and clearing services between 1995-2000, save     
minor exceptions. Therefore, the Helsinki District Court rejected the claims of 
those twenty banks and brokerage firms. The Helsinki Court of Appeal has now    
upheld this decision.                                                           

The decision of the Helsinki Court of Appeal may be appealed to the Supreme     
Court only if leave to appeal is granted by the Supreme Court.                  

The lawsuit in the Helsinki District Court still continues between two banks and
brokerage firms and OMX Exchanges Ltd, Helsinki Stock Exchange Ltd. and APK. The
amount claimed by these two claimants is about EUR 493,000 plus interest.
