NYFIX Brings Dark Pool of Liquidity to Europe
Euro-Millennium will go live in 2007

LONDON, June 18, 2007 – NYFIX, Inc. today announced the introduction of Euro-Millennium, an alternative trading system for pan-European listed cash equities. The service, which is scheduled to go live in Q4 2007, will be a UK regulated Multi-Lateral Trading Facility (MTF) for non-displayed liquidity in pan-European listed cash equities.

The Company revealed that it was on track with its plans for launching the service. A management team based in London is running the project and an Advisory Board of senior market participants from both Buy-Side and Sell-Side firms from across Europe has been established. Drawn from all facets of the European investment community, the Advisory Board has been created to guide and advise on specific workflow, functionality and commercial aspects to meet European market needs.

Euro-Millennium will draw on the experience gained in operating the successful Millennium ATS, NYFIX’s US based equity “dark pool”which has been in operation since 2001. Euro-Millennium will be open to all Buy-Side and Sell-Side professional market participants and will offer a continuous matching pool, executing orders in accordance with client-determined profiles. There are no bids and offers displayed to the market, hence the term “dark pool”, with executions being anonymous between the two counterparties.

“We are offering Euro-Millennium in response to unprecedented developments within the European regulatory environment and to important changes in the way liquidity is being sourced,” said Howard Edelstein, CEO of NYFIX, Inc. “As the operator of one of the most successful neutral dark pools in the United States and one of the leading innovators in this space, we are well-positioned to support our clients’ needs for alternative trading technologies in Europe. We believe that dark pools will become an important complement to exchange liquidity in the new European environment and that the co-existence of these alternative market centers will allow market participants to optimize their trading strategies.”

Leveraging its experience with the US version, Euro-Millennium will offer clients the ability to participate in the pool by placing Conditional Orders, which reside in the service until matched, or by sending Pass-Through orders which participate in a single matching cycle in search of a match, before being onward routed to another destination of the client’s choice, all within milliseconds.

“European markets and client trading strategies are changing rapidly. 2007 will be remembered as the year in which the foundations for a more effective pan-European equity marketplace were laid. Driven by both the upcoming MiFID regulatory change and by the increased adoption of electronic trading, the demand for a service which enables market participants to find liquidity in a broad range of pan-European shares on an anonymous basis is now critical. Combine this need with the ability to limit information leak, reduce market impact and offer an ability to seek best execution and you have the reasons behind the launch of Euro-Millennium” said Chris Smith, Head of Business Development for Euro-Millennium.

NYFIX Introduces Millennium PLUS^TM
New Offering Expands Execution Opportunities, Combats Fragmentation

NEW YORK, June 18, 2007 – NYFIX Millennium LLC, operator of one of the industry’s leading non-displayed execution facilities, today announced the controlled release of Millennium PLUS^TM, a new feature of Millennium that aggregates disparate liquidity sources from throughout the securities industry. The new feature allows Millennium participants to generate anonymous liquidity alerts to external dark pools and other passive liquidity sources, significantly increasing execution opportunities for both Resident and Pass-Through Millennium PLUS orders. Millennium PLUS is currently being offered to a select group of clients and liquidity partners, with general availability expected in Q3 2007.

Millennium PLUS offers the unique benefit of allowing orders to interact with a broad universe of liquidity while preventing information leakage and minimizing market impact. As part of the current controlled launch, Millennium PLUS is being used by a select group of early adopters. These firms have increased their match rates within Millennium by as much as 100%.

“With the ever-increasing amount of liquidity fragmentation in today’s financial markets, it has become more and more difficult for market participants to effectively source the best opportunities for execution,” said Brian Carr, CEO of NYFIX Millennium LLC. “By introducing Millennium PLUS, we are providing an efficient way to defragment and reaggregate disparate liquidity. Along with our recently-released liquidity sourcing algorithms, Millennium PLUS will be a key component of our liquidity aggregation strategy in the future.”

A Millennium PLUS order allows participants to generate liquidity alerts to third-party sources known as Passive Liquidity Partners (PLPs). These liquidity partners include systematic Buy-Side funds, external dark pools, broker internalization engines, and other pockets of hidden liquidity from across the industry. Unique to NYFIX Millennium, Millennium PLUS liquidity alerts are delivered only to computer-based systems holding live orders, rather than to traders’ screens. As a result, liquidity alerts will not be visible to

8

traders or systems which may cause information leakage or market impact. Both Resident and Pass-through orders can be designated as PLUS Orders. Pass-through PLUS Orders are held in Millennium for several hundred milliseconds, just long enough for PLPs to receive the liquidity alert and automatically respond. If no response is forthcoming, the order is passed on to the appropriate market center in the usual fashion.

“The ability to aggregate dark pools is of absolute value with the significant amount of the fragmented and hidden liquidity in today’s market,” commented Larry Tabb, co-founder and CEO of TABB Group, a leading research and advisory firm to the financial markets. “With the proper tools, market participants will be able to much more effectively navigate the murky world of dark liquidity while minimizing information leakage, managing market impact and attaining the best execution possible.”

In a research report released earlier this year, TABB Group predicted that volume of non-displayed liquidity execution will reach nearly 1.5 billion a day by 2010, representing 15% of total equity market share.

Launched in 2001, NYFIX Millennium has been at the forefront of the dark pool movement and has built one of the largest liquidity centers in the industry, touching more than a billion shares a day. Matched shares in Millennium now average more than 50 million daily. On May 1, 2007, NYFIX Millennium set a single-day volume record by matching more than 80 million shares.
