OMX, in conjunction with ISE, to deliver new trading system to DEX™ - Derivatives Canada

OMX, a leading expert in the exchange industry, has signed a contract to
deliver and support a new trading system for DEX, the new Canadian derivatives
market.  DEX is jointly owned by TSX Group Inc., the leading Canadian exchange
group for Canadian equity and energy securities, and International Securities
Exchange (ISE), the world's largest equity options exchange.  OMX will be the
system provider for the license, customization, implementation and support of
DEX's new derivatives trading system.  DEX is scheduled to begin operations  in
March 2009. 

“We are excited to expand upon our technology partnership with OMX to deliver a
superior technology platform for DEX,” said Thomas Ascher, ISE's Chief Strategy
Officer and a Director of DEX. “Building a stable and high-performance
technology infrastructure is clearly a critical element that will enable the
success of our venture with TSX, and we are confident that we will be able to
achieve those objectives with the OMX solution.” 

“The growth potential for derivatives in Canada is enormous,” said Rik
Parkhill, President TSX Markets and a Director of DEX.  “The agreement with ISE
and OMX gives DEX a solid foundation from which to build its Canadian
derivatives business and to offer our customers maximum flexibility and
choice.” 

“We are thrilled to be working hand-in-hand with one of our key clients, ISE,
to bring a proven technology solution to a new market,” said Markus Gerdien,
President, Market Technology, OMX.  “This venture brings our relationship with
ISE to a new level as we leverage our combined expertise to deliver and
maintain the DEX platform and further strengthen our position in North
America.” 

DEX, which is scheduled to launch in March 2009, will list and trade options,
futures and options on futures on a wide variety of Canadian securities. Among
the products to be listed on DEX will be derivative products based on the
S&P*/TSX Equity indices.
