SIX Swiss Exchange migrates to new trading platform based on NASDAQ OMX technology

STOCKHOLM, April 24, 2009 - The NASDAQ OMX Group, Inc. (NASDAQ:NDAQ) announces  
that SIX Swiss Exchange has completed its migration to a new trading platform   
known as ‘SWXess,' based on NASDAQ OMX market technology. The SWXess platform   
enables trading of all SIX Swiss Exchange products, including equities, fixed   
income, exchange traded funds and securitized derivatives, on a single platform.

SIX Swiss Exchange has now completed its phased member migration following its  
initial launch of SWXess in February. The implementation was successful and the 
new trading platform received positive acknowledgement from members and the     
investing public. The SWXess trading platform, which replaces SIX Swiss         
Exchange's in-house system, is built to enhance performance, latency and volume 
capacity for all of its markets.                                                

“In today's increasingly competitive exchange industry, high-end technology is a
key differentiator in order to continue to grow volumes and introduce new and   
innovative products,” said Mr. Christoph Bigger, CEO SIX Swiss Exchange. “NASDAQ
OMX provides the core of our new system, which will bring significant           
performance benefits to our customers and also reinforces our commitment towards
being an exchange in the technology forefront.”                                 

“We are extremely proud to be the key technology partner for a world-leading    
exchange like SIX Swiss Exchange,” said Magnus Böcker, President NASDAQ OMX.    
“The launch of the SWXess trading platform should truly be considered a         
milestone project, and we are confident that it will provide a solid foundation 
for the efficiency, credibility and innovation that defines the SIX Swiss       
Exchange.”
