On October 9, 2007, NYFIX, Inc. (the “Company”) filed a Current Report on Form 8-K with the Securities and Exchange Commission reporting, among other things, the adoption by its Board of Directors of the NYFIX, Inc. 2007 Omnibus Equity Compensation Plan and the grant of stock options and restricted stock awards under that Plan.  Among the awards reported on in the Form 8-K was a performance-based stock option for 1,428,855 shares of common stock granted to P. Howard Edelstein, the Company’s President and Chief Executive Officer.  That option was granted to Mr. Edelstein pursuant to a Non-Qualified Stock Option Agreement (Performance-based Vesting), which was filed as Exhibit 10.4 to the Form 8-K.  The Company inadvertently filed an incorrect version of Mr. Edelstein’s Agreement with the Form 8-K; the incorrect version, among other things, did not properly describe when earned performance awards vest.  This Amendment No. 1 is being filed for the purpose of filing the correct version of Mr. Edelstein’s Agreement.  The description of Mr. Edelstein’s performance-based option in the body of the Form 8-K was accurate.
