RTS PRESS RELEASE

London/Frankfurt, April 22, 2008 - RTS Realtime Systems Group, a leading trading solutions provider, announced that it has committed to provide connectivity to the new European equity trading venue, Turquoise, which will be launched in September.

Turquoise, which under the new MiFID regulation is defined as a multi-lateral trading facility (MTF), was established by nine leading European investment banks as a pan-European, open equity trading platform on which all participants will have equal access.  The nine backers have also committed to make markets in Europe’s leading stocks so that Turquoise will have an immediate critical mass of natural liquidity from day one.

Eli Lederman, Chief Executive Officer of Turquoise said: “Turquoise will transform the European equity marketplace when it starts trading in early September and we are pleased that RTS has agreed to be a participant from the start. It is through partners such as RTS that Turquoise will benefit from access to a further important market segment and swiftly establish the platform as a real force in European equity trading."

Turquoise will begin trading in 1,500 stocks across 14 countries in September. The exchange will be comprised of two segments. 300 stocks will be traded in the integrated market segment where visible and dark orders will interact continuously. A further 1,200 stocks will trade in the dark only market.

RTS offers access through its Realtime Trading Desktop (RTD) portfolio, including its RTD-API’s, the RTD front-end trading system, and RTD Tango, its high performance automated algorithmic trading solution.

Additionally, RTS will be proving direct market access to the new marketplace in its data center and hosting facilities across the world.
