NYFIX, INC.
2001 STOCK OPTION PLAN
MODEL
NON-QUALIFIED STOCK OPTION AGREEMENT
(TIME VESTING)

Non-Qualified Stock Option Agreement (this “Agreement”), dated as of October 2,
2007 (the “Date of Grant”), between NYFIX, Inc. (“NYFIX”) and P. ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇ (the
“Participant”).

BACKGROUND

                    Pursuant to the terms of the NYFIX, Inc. 2001 Stock Option Plan (the “Plan”),
NYFIX desires to (i) provide an incentive to the Participant, (ii) encourage the Participant to
contribute materially to the growth of NYFIX and its subsidiaries (collectively, the “Company”)
and (iii) more closely align the Participant’s economic interests with those of NYFIX stockholders
by means of a grant of Nonqualified Options. Whenever capitalized terms are used in this
Agreement, they shall have the meanings set forth in this Agreement or, if not defined in this
Agreement, as set forth in the Plan.

                    The Plan allows the Company to provide rewards and incentives to certain
employees of the Company by, among other things, granting them opportunities to purchase shares
of Stock. The Board or the Committee has determined that it would be in the best interest of the
Company and its stockholders to grant the Options to the Participant under the Plan.

                    In consideration of the covenants and agreements set forth in this Agreement, the
Participant and NYFIX hereby agree as follows:

ARTICLE I

GRANT OF OPTIONS

                    1.1     Grant of Options. The Participant is hereby granted Nonqualified Options
representing the right to purchase 675,069 shares of Stock subject to the restrictions and conditions
set forth in this Agreement. References in this Agreement to “Option” and “Options” mean the
options granted hereby, individually and in the aggregate.

                    1.2     Option Price. The purchase price of each share of Stock underlying the
Options is $4.60 per share (the “Option Price”), which is the same as the Fair Market Value of a
share of Stock on the Date of Grant.

                    1.3     Grant Information. The Options have been granted under the Plan. The
Committee authorized the grant of the Options on October 2, 2007.

ARTICLE II

EXERCISABILITY OF OPTIONS

                    All of the Options are unvested on the Date of Grant. Options shall vest upon, but
only upon, the earliest to occur of the events described in Section 2.1, 2.2 or 2.3 and shall become
exercisable as described in Section 2.4, in each case subject to the limitations set forth in Section
2.5. All unvested Options shall be forfeitable as set forth in Section 2.5 and shall be non-
transferable as set forth in Section 5.2. All shares of Stock issued upon exercise of Options shall be
transferable, although:

                    (a)     transferability may be subject to pre-clearance, blackout, registration
and other requirements and restrictions under the Company’s ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇ and other compliance
policies and procedures; and

                    (b)     transfers by executive officers should be reviewed in advance to
determine if there would be any potential liability for short-swing profits under Section 16(b) of the
Securities Exchange Act of 1934.

                    (i)     Time Vesting. If not sooner vested and unless previously forfeited
pursuant to Section 2.5, all of the Options shall vest based on the passage of time as follows:
2.7778% of the Options shall vest on October 4, 2007 and on the fourth day of each month
thereafter through and including September 4, 2010.

                    If a partial Option would vest on any date, the total number of Options vesting
on such date shall be rounded up to the nearest whole Option.

                    2.2     Accelerated and Continued Vesting. If not sooner vested and exercisable,
and unless previously cancelled pursuant to Section 2.5 or 4.2,

                              (i)    all of the Options shall vest and become immediately exercisable
upon a termination of the Participant’s employment (a) by the Company without Cause (as defined
in Section 5.1) or (b) by the Participant for Good Reason (as defined in Section 5.1), in either case
within one year following a Change in Control (as defined in Section 5.1);

                              (ii)    following a termination of the Participant’s employment (a) by the
Company without Cause or (b) by the Participant for Good Reason, in either case prior to or more
than one year following a Change in Control, the Participant’s Options that would have vested
through the month that includes the last day of the period for which the Participant receives
severance, if any, following such termination (the “Severance Period”), shall immediately vest; and

                              (iii)   in the event of a termination of the Participant’s employment by
reason of death, the Participant’s Options that would have vested during the nine-month period
following such termination may become immediately vested upon such termination in accordance
with the terms of Section 5 of the Employment Agreement between the Company and the
Participant dated September 4, 2006, as amended from time to time (the “Employment
Agreement”).

                    2.3     Discretionary Vesting and Exercisability. The Committee or the Board may
accelerate the vesting of any or all of the Options at any time and for any reason.

                    2.4     Exercise; Restriction on Exercise. No unvested Options shall be exercisable.
All vested Options shall become exercisable at the time they first vest and shall cease to be
exercisable at the time they expire and are forfeited as provided in Section 2.5 or Article IV.

                    2.5     Effect of Termination of Employment on Vesting; Expiration of Unvested
Options. All unvested Options expire upon the earliest to occur of:

                              (i)     the time of notification of the termination of the Participant’s
employment by the Company for Cause;

                              (ii)    termination of the Participant’s employment for any reason other than
