NYFIX REACHES NEW MILESTONE IN CONNECTIVITY;

THE NYFIX NETWORK CONNECTS ITS 250^TH BUYSIDE CLIENT

NEW YORK, June 13, 2006 - NYFIX, Inc. today announced that it has brought its 250^th buy-side client, San Diego-based Wagonhound Investments LP, live on the NYFIX Network. The NYFIX Network connects to more than 450 trading counterparties worldwide with over 5,000 connections in production. The NYFIX Network infrastructure for FIX messaging traffic consists of 795 telecom lines and 125 customer VPNs (virtual private networks). This equates to more than 1,500 frame relay PVCs (permanent virtual circuits) globally.

ING Investment Management Americas, another recently connected buy-side client, chose the NYFIX Network for FIX connectivity because of NYFIX’s longevity in the space and its commitment to FIX routing globally. “We have been extremely pleased with the implementation of over 100 broker connections and continue to be impressed by the support we receive,” said Kevin P. McMahon, Senior Vice President, ING Investment Management Americas.

The NYFIX Network’s “hub and spoke” infrastructure serves clients throughout Europe, Asia and North America. It has seen a steady increase in counterparty connectivity and adoption of the NYFIX FIX Products suite during the first half of 2006. The NYFIX Network’s value added products such as its real-time trade execution quality monitoring product, NYFIX eQ^TM, and its FIX monitoring and control product, TradeScope®, strongly distinguish it from the competition.

“We are building aggressively on our position as North America’s #1 FIX Network provider and #1 Global FIX Engine¹ provider with exciting new products and first class global support,” said Andrew Wilson, Global Head of The NYFIX FIX Products Division. “Our steady and continued growth in electronic connectivity amongst trading counterparties is a real tribute to our employees and the intellectual capital, expertise, and focus they bring to bear on this marketplace every day.”
