Item 1.01.    Entry into a Material Definitive Agreement

On April 4, 2008, NYFIX, Inc. (NYFIX), through its wholly-owned NYFIX Global Services, Ltd. subsidiary, executed a share purchase agreement for the acquisition of FIXCITY, Ltd., a U.K.-based specialist in web-based electronic trading and liquidity discovery solutions.

Pursuant to the terms of the share purchase agreement, NYFIX paid Pounds Sterling 3.3 million (or approx. $6.6 million) in cash to acquire 100% of the outstanding equity in FIXCITY from its individual founders Karl Breeze, Amy Muddimer, Paul Scott, Andrew Southon and Matthew Barkway.

NYFIX also agreed to pay an additional $1.0 million in cash consideration contingent on the successful completion of the integration of the existing FIXCITY and NYFIX technology platforms within six months of the closing date.

In addition, the share purchase agreement provides the potential for cash earn-out payments in years 1, 2 and 3 following the acquisition totaling up to Pounds Sterling 3.7 million (or approx. $7.4 million) if certain revenue targets are achieved, with potential additional payments to be based on varying percentages of all such revenue if higher level target thresholds are achieved.

The acquisition was completed on April 4, 2008.
