IT - INET Nordic - NASDAQ OMX Nordics and Baltics
introducing Volatility Guards                    

NASDAQ OMX Nordic will introduce Volatility Guards on its Nordic and Baltic     
equity markets to reduce the likelihood of trading incidents and to reduce the  
impact of sudden and extraordinary liquidity.                                   

The NASDAQ OMX Nordic Volatility Guard is a trading pause and resumption process
designed to restore an orderly market in a single order book traded on NASDAQ   
OMX Nordic and Baltic exchanges in Stockholm, Helsinki, Copenhagen, Iceland,    
Tallinn, Riga and Vilnius.                                                      

The Nordic Volatility Guards will be utilized if an order deviates too much in  
percentage from the last sale price (Dynamic Volatility Guard) or from the      
reference price, which is normally the day's opening price (Static Volatility   
Guard). When the Volatility Guard is triggered, continuous trading is halted    
followed by an auction period which lasts 60* seconds, after which the order    
book moves back to continuous trading.
