Corvil Solution Used to Provide Performance Transparency for Clients of Nomura's Next Generation Trading System

LONDON and NEW YORK, April 19, 2011 - Corvil, a provider of latency management systems for high performance
trading and market data, today announced that Nomura, the global investment
bank, is using Corvil's latency management system to monitor the European
performance of NXT Direct its global ultra-low latency trading platform.
Following a comprehensive evaluation process, Corvil was selected and used to
measure the latency of Nomura's platform at 2.8 microseconds, creating a new
benchmark for trading system speed in Europe.

Nomura deployed CorvilNet for complete monitoring of NXT Direct, which
offers co-located software hosting and ultra fast connectivity to major
exchanges and MTFs in Europe. The platform also delivers a seamless
integration with Nomura's NXT products incorporating market access, market
data and order routing. CorvilNet is deployed to monitor latency within
Nomura's NXT Host co-location infrastructure and all aspects of network
latency and performance between co-location sites across Nomura's proprietary
dark fiber network.

Andrew Bowley, Head of Electronic Product, EMEA said, "Nomura has made
significant investments to develop NXT Direct and to grow our market share
across all European equities. Demonstrating the true latency performance of
NXT Direct and assuring the lowest latency for our clients is crucial. Since
deploying Corvil technology we have been able to keep latency and loss at
negligible levels for clients who benefit from high performance execution."

Corvil technology measures and reports on latency in real-time for all
order transaction flows, market data feeds, and network speed and
performance. This unique approach enables the immediate identification of the
root-cause of latency, whether it is in the network or application layer. For
client order flow, CorvilNet provides nanosecond-precision latency visibility
on every packet, message and transaction. This makes it much more efficient
to handle customer queries on trading latency or missed fills, with quick and
flexible access to days, weeks or months of trading records.

"Nomura's NXT Ultra Low Latency Trading Platform provides groundbreaking
connectivity to major exchanges and MTFs throughout Europe. We are delighted
not only to strengthen our relationship with Nomura but also that CorvilNet
was used to validate the performance of their advanced execution technology
to latency sensitive clients," said Corvil CEO, Donal Byrne.
