Expanding memberships and influx of
new members on the Nordic Exchange 

The Nordic Exchange is presently seeing an influx of new members, and existing  
members are expanding their memberships to include more markets in order to     
enjoy the advantages of the OMX Nordic Exchange membership. All in all eight new
members have joined the Nordic Exchange and 13 members have expanded their      
membership this year.                                                           

”It is a pleasure to see the continuously increasing interest in achieving      
direct trading access to the Nordic Exchange expressed by Nordic as well as     
non-Nordic securities houses. We have created a market of such size that we are 
now a leader in several industries, including paper, fashion and IT,” says Jukka
Ruuska, President of Nordic Marketplaces at OMX.                                

Over the summer the Amsterdam-based brokerage house All Options B.V. has joined 
the Nordic Exchange in Stockholm and Helsinki. In addition, today we welcome    
Norwegian Artic Securities ASA as a new member in Stockholm. During September,  
Flow Traders from Amsterdam will join the Danish, Finnish and Swedish markets   
and become the ninth new member on OMX Nordic Exchange.                         

Moreover, BNP Paribas, Paris, and IMC, Amsterdam, which were already members in 
Stockholm and Helsinki, have extended their membership of the Nordic Exchange to
include the Danish market. In July, Saga Capital Investment Bank hf and NordVest
Securities Ltd - both based in Iceland - have expanded their membership to      
Stockholm and Helsinki. Van der Moolen has had access to the Finnish market and 
in July they have expanded their membership to include the Swedish equity       
market. Last week Van der Moolen joined the Danish market and will soon add on  
the Icelandic market. EIK Bank A/S based in Copenhagen expended its membership  
to OMX Nordic Exchange Iceland in July and to Stockholm as of August 27, 2007.  

Moreover, All Options is going to broaden its activities to also cover the      
Danish equity market within short time.                                         

Today, there are 162 banks and brokerage firms trading on one or more markets   
within OMX Nordic Exchange.
