TSX Quantum Revolution(TM) continues to take shape

    Key technology upgrade successfully completed

    TORONTO, June 28 /CNW/ - TSX Group Inc. has successfully completed the
next step in the transition to the TSX Quantum Revolution by deploying core
trading engine hardware with new HP Integrity NonStop servers that use the
Intel(R) Itanium(R) 2 processor.
    TSX Group CIO Brenda Hoffman said the new installation, part of the
TSXpress(TM) initiative, has improved on TSX Group's current trading
environment. "This is making our system more efficient as we increase order
throughput and at the same time decrease order response times. We are already
seeing considerable improvements in these areas."
    The Itanium upgrade is aimed at maximizing efficiencies on the current
platform. TSXpress is the final step before the scheduled implementation of
TSX Quantum - the new trading and technology platform that will begin rollout
later this year. This new platform, based on new blade technology, is expected
to have leading messaging capabilities to be able to meet the ever-changing
needs of the marketplace and have response times in the single digit
millisecond range, equal to, or better than, any equities exchange group in
the world.
    TSX Group CEO Richard Nesbitt again reminded the marketplace that TSX
Quantum will require participants to prepare for this implementation. "We will
be adding substantial performance and capacity to the markets in the next
year. We want to offer our customers the opportunity work with us to prepare
as we look to the future."
