This agreement enhances Townsend Analytics' longstanding relationship with Credit Suisse. Townsend Analytics is a leading provider of multi-broker, multi-asset, multi-currency and multi-route electronic trading solutions for the global capital markets. The alliance enables Credit Suisse's clients to directly route U.S. and European equity orders to AES using RealTick, where they can employ a specialized suite of algorithmic trading strategies developed by Credit Suisse's team of quantitative analysts and traders.

Already renowned worldwide for its algorithmic trading offerings, Credit Suisse will be expanding the total number of equity algorithmic trading strategies available through RealTick in the second quarter of 2007. The agreement also allows Credit Suisse to quickly develop customized algorithms in the future as the need arises.

Through RealTick, clients can also access Credit Suisse's internal crossing network, or "dark pool," that anonymously matches buy and sell orders. As one of the world's largest internal crossing engines, CrossFinder offers clients immense liquidity, anonymity, and the ability to execute large blocks of stock with less impact than would be likely in the public markets.

"RealTick allows our clients to quickly access both traditional electronic networks as well as CrossFinder, all simultaneously from a single platform," said Guy Cirillo, AES Global Channel Sales Manager at Credit Suisse. "In addition, with Credit Suisse's proprietary algorithms built into the interface, we are giving our clients a true single-source solution for all their electronic equity trading needs in the major global markets," he added.

"We are excited to be adding Credit Suisse to our global multi-broker network and enabling clients to achieve best execution through RealTick," comments Thomas Kim, Managing Director, Global Head of Trading Services for Townsend Analytics. "And with the direct connection to Credit Suisse's large CrossFinder pool, Townsend continues its quest to offer access to all major global liquidity sources with complete anonymity," Kim adds.
