NYFIX SIDEKICK IOI/AT SERVICE REACHES CRITICAL MASS
AS EIGHT LEADING BROKER-DEALERS JOIN COMMUNITY
Over 100 Brokers Now Sending IOIs and Advertised Trades to More Than 150 Institutions

NEW YORK, December 13, 2006 – NYFIX, Inc. (Pink Sheets: NYFX) today announced that eight of the leading global broker-dealers have signed agreements for the real-time distribution of Indications of Interest (IOIs) and Advertised Trades (ATs) to the buy-side via NYFIX. These firms – BNY Brokerage, Credit Suisse, Deutsche Bank, Jefferies & Company, Inc., JPMorgan, Knight Capital Group, Lehman Brothers and Merrill Lynch – join charter providers Citigroup, Goldman Sachs and Morgan Stanley within a community of over 100 broker-dealers now sending IOIs and ATs to more than 150 buy-side institutions over the NYFIX infrastructure.

One of the signing brokers, Lehman Brothers, has decided to leverage its long-time relationship with NYFIX to enhance the way it distributes this type of data to its trading counterparties. “We view NYFIX as a thought leader in the space and are excited about the innovations they are bringing to this area,” said Ben Chrnelich, CAO Equity Liquid Markets, Lehman Brothers. “We look forward to expanding this partnership and creating efficiencies for our mutual buy-side clients.”

An Indication of Interest, or IOI, is an expression of intention to buy or sell securities broadcast by broker-dealers to its institutional counterparties. This information is distributed with the hope of finding an opposite party for the transaction, thus creating a natural (institution to institution) trade execution for a broker-dealer. In early 2006, NYFIX launched its Sidekick® IOI/AT service to deliver IOIs and ATs to buy-side trading desktops and Order Management Systems. Key features of the service include NYFIX’s advanced filtering capability and data validation tools, designed so that only relevant information is delivered to buy-side traders. The IOI/AT service has seen a steady increase in counterparty connectivity since its launch.

“As a neutral provider of innovative technology solutions surrounding the trade lifecycle, NYFIX is uniquely positioned to provide quality information in a segment where we believe that spam and distorted data are the norm,” said Barry Smith, head of Business Development at NYFIX. “In our view, this IOI/AT service produces a better user experience for the buy-side while creating more trading opportunities for the sell-side.”

NYFIX SIDEKICK IOI/AT SERVICE REACHES CRITICAL MASS
AS EIGHT LEADING BROKER-DEALERS JOIN COMMUNITY
Over 100 Brokers Now Sending IOIs and Advertised Trades to More Than 150 Institutions

NEW YORK, December 13, 2006 – NYFIX, Inc. (Pink Sheets: NYFX) today announced that eight of the leading global broker-dealers have signed agreements for the real-time distribution of Indications of Interest (IOIs) and Advertised Trades (ATs) to the buy-side via NYFIX. These firms – BNY Brokerage, Credit Suisse, Deutsche Bank, Jefferies & Company, Inc., JPMorgan, Knight Capital Group, Lehman Brothers and Merrill Lynch – join charter providers Citigroup, Goldman Sachs and Morgan Stanley within a community of over 100 broker-dealers now sending IOIs and ATs to more than 150 buy-side institutions over the NYFIX infrastructure.

One of the signing brokers, Lehman Brothers, has decided to leverage its long-time relationship with NYFIX to enhance the way it distributes this type of data to its trading counterparties. “We view NYFIX as a thought leader in the space and are excited about the innovations they are bringing to this area,” said Ben Chrnelich, CAO Equity Liquid Markets, Lehman Brothers. “We look forward to expanding this partnership and creating efficiencies for our mutual buy-side clients.”

An Indication of Interest, or IOI, is an expression of intention to buy or sell securities broadcast by broker-dealers to its institutional counterparties. This information is distributed with the hope of finding an opposite party for the transaction, thus creating a natural (institution to institution) trade execution for a broker-dealer. In early 2006, NYFIX launched its Sidekick® IOI/AT service to deliver IOIs and ATs to buy-side trading desktops and Order Management Systems. Key features of the service include NYFIX’s advanced filtering capability and data validation tools, designed so that only relevant information is delivered to buy-side traders. The IOI/AT service has seen a steady increase in counterparty connectivity since its launch.

“As a neutral provider of innovative technology solutions surrounding the trade lifecycle, NYFIX is uniquely positioned to provide quality information in a segment where we believe that spam and distorted data are the norm,” said Barry Smith, head of Business Development at NYFIX. “In our view, this IOI/AT service produces a better user experience for the buy-side while creating more trading opportunities for the sell-side.”
