BT RADIANZ SIGNS LARGEST EXCHANGE IN ASIA-PACIFIC

BT Radianz to carry Tokyo Stock Exchange market data

New York (June 21, 2005) - BT Radianz, the leading global provider of financial connectivity services, and Tokyo Stock Exchange today announced the development of a global distribution platform through the BT Radianz shared market infrastructure for the Exchange’s MAINS (MArket INformation System) data feed to customers outside of Japan. This makes Tokyo Stock Exchange the fourth major equities exchange in the Asia-Pacific region to become a BT Radianz Provider. The other Asia Pacific exchange Providers include the Australian Stock Exchange (ASX), the Hong Kong Stock and Futures Exchange (HKEx) and Singapore Exchange (SGX).

The arrangement between Tokyo Stock Exchange and BT Radianz will provide market data vendors as well as buy- and sell-side institutions with a direct exchange feed that will improve overall performance and better manage latency issues. Along with Tokyo Stock Exchange, BT Radianz Providers include more than 30 other major equities and equity derivatives execution venues around the world. Development of Tokyo Stock Exchange’s interface to the BT Radianz shared market infrastructure is underway with availability of the platform expected in Q4 2005.

Toshiya Fujiwara, Manager of Information Products at Tokyo Stock Exchange, Inc., said:

"We are seeing an increased demand for fast, direct access to our market data feeds from overseas customers. Since a large majority of these customers already use BT Radianz’s shared infrastructure, it was a natural choice to select BT Radianz to deliver our market data to the widest range of potential customers with as little latency as possible. Moreover, BT Radianz’s global scope will help our efforts in other major market centers worldwide."

Richard Man, Head of Sales for BT Radianz in Asia-Pacific, said:

"BT Radianz customers across the globe are demanding lower latency and direct access to more exchanges. As the second largest equity exchange in the world, Tokyo Stock Exchange is a great addition to the BT Radianz community both in the Asia-Pacific region and globally. The TSE’s selection of BT Radianz further recognizes our shared market infrastructure as the choice for fast access to the four major stock exchanges in Asia-Pacific."
