Business Editors

STAMFORD, Conn.--(BUSINESS WIRE)--March 19, 2001

NYFIX, Inc. (NASDAQ: NYFX) announced that its broker/dealer affiliate, NYFIX Millennium L.L.C., has successfully commenced a strategic expansion plan to include several more leading US financial institutions as advisors and shareholder members in the NYFIX Millennium L.L.C. partnership. NYFIX Millennium is pleased to announce that it has closed the first new memberships with additional closings and funding expected in the near term.

This expansion precedes an aggressive marketing campaign scheduled to commence in April 2001, together with other initiatives targeting the development of a substantial increase in the industry awareness of the benefits of the NYFIX Millennium Alternative Trading System (ATS).

"While some elements of the markets' operations have always been a point of contention, the advent of decimal trading has highlighted key issues and is pushing the tolerance of the institutional trading community. We think the NYFIX Millennium Model is most timely and the NYFIX trading network and team provides solid leverage to the situation. We see our participation in NYFIX Millennium as a direct investment in our commitment to provide our clients with the highest level of trade execution quality and service available," commented James W. Whelen III, Head of Listed Trading at First Union Securities, a new NYFIX Millennium L.L.C. partner.

NYFIX Millennium, in addition to its execution facilities, is the first ATS (ECN) to provide simultaneous broad access to the liquidity of the traditional listed markets via the NYFIX order routing network. "While we bring record order routing volume and Millennium's unique capability to allow the market exposure of large blocks of shares without causing pre-market impact, the current partners and new members of the team bring trading expertise, share volume and market visibility to the table," said Peter K. Hansen, Chief Executive Officer and President of NYFIX, Inc.

Although the details of the agreements were not disclosed, the expansion is a round-table style investment, with each partner contributing two million dollars. NYFIX, Inc. secured certain provisions to maintain its ownership ratio relative to the overall partnership.
