New York, December 19, 2005:

SDS and TradeMatch ATS enter into multi-year pact to deploy the SDS Electronic Trading System to launch an electronic marketplace for fixed income securities.

SDS Financial Technologies Inc.(SDS), a leading provider of market data and electronic trading systems, announced today that Seaboard Securities, Inc. has entered into multi-year agreement to deploy the SDS Electronic Trading System (ETS) to power TradeMatch ATS, an Electronic Marketplace for US Treasuries, US Treasury Benchmark Futures and Repurchase Agreements (Repo). TradeMatch ATS is a total "Electronic Marketplace for Fixed Income".

TradeMatch ATS will initially trade Repo, Benchmark Treasuries and Treasury Futures Contracts and will be expanded to other products and markets. By bringing fixed income to an exchange type-matching engine, TradeMatch ATS will link the three markets and offer the most efficient execution available today. Advanced functionality will include auto-spreading capabilities applied to a First-In-First-Out (FIFO) matching engine. Traders will now have the assurance of executing basis, yield curve or cross market trades at their desired spreads in the most cost effective manner.

The SDS Electronic Trading System is a comprehensive matching, routing and market data system. The system is an "Exchange in a Box" and includes;
-FIFO Matching Engine
-Trader's Terminal
-Clearing and Settlement Interfaces
-FIX Engine -Risk Management and Supervision
-FIX Routing API -Post Trade Feed
-FIX Market Data Feed API

The software uses multi-threaded technology, allowing the system to handle 8000 messages and 2000 transaction per second. It is scalable to 100,000 orders and 20,000 trades per second. The System's rules-based matching engine can be rapidly modified for new rules, new strategies and new product classes. The Trader Terminal includes an order book, market depth, advanced alerts and order management functionality.
