ITEM 1.01.  ENTRY IN A MATERIAL DEFINITIVE AGREEMENT.

     On November 4, 2004, NYFIX, Inc. (the "Company") executed Amendment No.1 to
the  Executive  Employment  Agreement  between the  Company and Peter  Kilbinger
Hansen,  the Company's  President and Chief Executive  Officer.  Pursuant to the
amended  agreement,  which reflects the oral agreement of the parties as of July
1, 2003, there is no change in Mr. Hansen's base salary of $400,000 per year, or
in the provision that any bonus or additional compensation may be awarded at the
discretion of Company's  Board of Directors.  The amendment  eliminates from the
Executive Employment Agreement provisions relating to specified annual increases
in base salary and sales  commissions for Mr. Hansen's direct sales efforts with
respect  to  products  sold by the  Company.  All  other  terms of Mr.  Hansen's
employment agreement remain unchanged.
