Javelin Rolls Out AppiaTM 3.0; Introduces TradeScopeTM FIX Monitoring Tool New Products on Display at SIA Technology Management Exhibition in New York

NEW YORK - June 16, 2003 - Javelin Technologies, a FIX industry pioneer and
wholly-owned subsidiary of NYFIX, Inc. (NASDAQ: NYFX), today announced the release of TradeScope, a comprehensive alerting and monitoring tool for financial firms' FIX (Financial Information eXchange) connectivity operations, as well as a new version of its flagship, industry-leading trade infrastructure and messaging software, Appia.

TradeScope will provide FIX users in the buy-side, sell-side and exchange communities with the ability to easily monitor and manage all of their FIX-based trading activities. With significantly reduced performance demand on the user's FIX engines, a light-weight browser-based front-end, and multi-level access controls, TradeScope simplifies and brings greater efficiencies to the practice of FIX monitoring. Proactive alerts also allow IT managers to troubleshoot connectivity problems quickly, saving valuable time and money.

"As the FIX protocol has continued to proliferate throughout the industry, the task of managing these environments has become much more daunting," explains John Coulter, president and COO of Javelin Technologies. "Only five years ago, most firms were only running a few FIX connections at a time. Now, the majority of firms in the industry, both large and small, are having to maintain hundreds of connections which has created the need for an affordable and easy-to-use process for monitoring and managing these activities."

"TradeScope is a user-friendly, enterprise-wide solution for traders, systems administrators and developers, which doesn't tax the overall performance of the FIX engines," Coulter continues. "If a firm has High Availability FIX engines in London, Tokyo and New York, TradeScope provides a global means of managing all FIX connectivity without having to sift through log files or write proprietary scripts."

In addition to the TradeScope release, Javelin announced that its latest version of Appia, Appia 3.0, now comes standard with Javelin's new Extensibility Framework (EF) architecture. Appia EF allows users to easily customize their FIX messaging on a per-counterparty basis, giving the user more control and improving the customer's time-to-market for custom requirements. Appia EF also enables users to extend the software for special needs or customizations by using plug-ins that can be inserted into Appia's main message processing path at pre-defined points. This makes it possible to configure the structure and contents of both inbound and outbound messages as well as allowing the re-routing of messages within Appia.

Appia 3.0 also comes with full support of the recently-released FIX 4.4 specification and message fragmentation.

"This version of Appia represents a significant milestone in terms of flexibility and user-control over FIX messaging," explained Ajay Kamdar, senior vice president of product development for Javelin Technologies. "One of the features of the FIX protocol is its inherent flexibility and the fact that it's open to user interpretation. With the Extensibility Framework now included with Appia many of the common inconsistencies between counterparty interpretations of the protocol can be easily corrected, which brings the true efficiencies gained by the FIX protocol to the forefront."

Both TradeScope and Appia 3.0 with EF will be on display in the NYFIX booth (#1418) at the June 17-19 SIA Technology Management Conference in New York. Appia and TradeScope are trademarks of Javelin Technologies, Inc.
