NYFIX, Inc. Announces Sale of OBMS Business Unit

New York, NY August 28, 2006: NYFIX, Inc. (Pink Sheets: NYFX). NYFIX, Inc. (“NYFIX”), a leader in technology solutions for the financial marketplace, today announced it has entered into a definitive agreement to sell all of the capital stock of NYFIX Overseas, Inc., a wholly-owned subsidiary which previously housed the Company’s Order Book Management Systems (OBMS) business, to G.L. Trade S.A., (“GL”).

The initial proceeds on this transaction are expected to approximate $7.7 million after taking into account purchase price adjustments based on the closing balance sheet of NYFIX Overseas and certain deductions of $1.3 million. NYFIX currently estimates recording a net gain on this transaction in excess of $4.5 million after deducting related legal, accounting and placement fees and the equity held in NYFIX Overseas just prior to the sale.

The OBMS business specializes in electronic trading solutions for the derivatives markets and develops order management workstations and exchange interface systems, supporting trading on more than 20 of the world's leading international derivatives exchanges.

“The sale of the OBMS business allows us to more precisely focus on the market opportunities that are available to the firm’s three remaining businesses. Our Order Management Systems, FIX Network, and Transaction businesses will benefit greatly from the narrowing of our product portfolio”, commented Robert C. Gasser, CEO, NYFIX, Inc.

NYFIX intends to use the proceeds of the sale for general corporate and working capital purposes.
