Singapore Exchange (SGX) Selects Corvil for Latency Management of Ultra High Speed Trading Platform and Co-Location Services

LONDON and NEW YORK, March 21, 2011 - Corvil, a provider of latency management systems for high performance
trading and market data, today announced that Singapore Exchange (SGX) has
selected Corvil's Latency Management System to monitor and assure the latency
performance of their new generation trading system, Reach. The Corvil
solution will also be deployed within SGX's colocation infrastructure to
manage latency between SGX members and the Reach trading platform.

In choosing the CorvilNet solution SGX highlighted Corvil's unified
latency management as being particularly important. CorvilNet is capable of
monitoring in real-time the latency for all order entry transactions, market
data feeds, and the network simultaneously in one platform. This enables
immediate visibility and root-cause analysis of latency issues and removes
ambiguity where it is challenging to pinpoint if the problem is at the
application layer or the network layer.

"We are making a significant investment in world class technologies to
develop SGX Reach. Our goal is to achieve both ultra-low latency and very
high throughput. By deploying the CorvilNet solution it enables us to assure
and demonstrate achievement of these objectives to our market participants.
We are delighted to add Corvil to our list of trading technology partners for
SGX," commented Bob Caisley, Chief Information Officer at SGX.

CorvilNet will be used for both internal latency monitoring of the Reach
trading platform and network, including the new SGX co-location facility. The
full end to end trading path from order entry through to trade update in the
market data feed will be monitored continuously with microsecond precision.

"SGX is building one of the world's most advanced trading platforms in
terms of speed, capacity and scalability. We are delighted that Corvil will
be used to assure that these objectives are met and help strengthen its
position as one of the premier venues in the world for the modern electronic
investor," said Corvil CEO, Donal Byrne.
