Dear

I
      am
      pleased to extend this offer of employment to you as Executive Vice President
      of
      NYFIX, Inc. (“NYFIX” or the “Company”) and as Chief
      Executive Officer of the Transaction Services Division of
      NYFIX (the
      “Division”) at our 100 Wall Street ,
      New
      York, New York location. In your new position, you will report directly to
      the
      Chief Executive Officer of NYFIX. Your employment
      commencement date (the “Employment Commencement Date”) will be
      the earlier of (i) March 1, 2008, and (ii) ten (10) days following the closing
      of the pending acquisitions of the Boston Stock Exchange, Inc. (“BSE”) by the
      NASDAQ and the Boston Options Exchange, Inc. by the Montreal Exchange, with
      the
      understanding that this agreement shall be
      terminable by
      written notice by NYFIX
      in its sole discretion, without further obligation by NYFIX to you, should
      you
      fail to commence full-time employment on or before March 1, 2008.




Your
      initial job duties shall be as set forth on Attachment A. (Please note that
      this
      offer is contingent upon you possessing the regulatory licenses required to perform your job duties, which
      consist of the Series
      7, Series 63 and Series 24 licenses).




You
      will
      be compensated at an annualized base salary of $ 300,000,
      which may be increased (but not decreased) in the sole discretion of NYFIX
      (the
“Base Salary”). In
      addition, you will receive a sign-on cash bonus
      of
      (a) $ 100,000,
      plus (b) $75,000 less any amounts that you may receive in stay bonus payments
      from another organization, pursuant to the written letter which you previously
      provided to NYFIX, which you would otherwise forfeit as a result of your
      employment hereunder (the “Sign-On Bonus”), less
      applicable withholdings, payable on the first payroll date following your Employment
      Commencement Date .
      The
      portion of the Sign-On Bonus referenced in subparagraph (a) above will be
      subject to full repayment to and recapture by NYFIX (net of all
      income and other taxes thereon )
      if you
      cease to be employed (unless terminated by NYFIX without “Cause“ or you elect to
      terminate your employment with the Company for “Good Reason”, both as defined in
      Attachment A) on or before the six -month
      anniversary of the Employment
      Commencement Date.




During
      your employment hereunder, you will
      be eligible to participate in the Annual Incentive Plan (“AIP” or cash bonus
      plan). Your cash bonus
      target will be set at 75% of Base Salary (the
“Target Bonus”) ,
      adjusted by multiplying the Target
      Bonus by a
      factor ranging from 0% to 200% based on actual consolidated revenue and
      operating EBITDA achieved by NYFIX. Your payout will be calculated on this
      adjusted performance target based on the achievement of Corporate (40%
      weighting), Division (40% weighting) and individual (20% weighting) goals
      established by the Company following discussion with you. For 2008 only, the guaranteed minimum
      payout under
      the
      AIP will
      be
      the 75% target amount, or $225,000, and such 2008 bonus will be prorated for
      the
      period of time employed unless your Employment Commencement Date is on or before
      March 1, 2008.







You
      also
      will be eligible to receive  an
      additional cash bonus (the
      “Additional Bonus”) for
      calendar 2008 based on annual incremental organic Division Net Revenue growth
      (excluding the impact of acquisitions) over calendar 2007 at the following
      rates:




**Cumulative
                  Amount**First

              4%Amounts
                  above $40 million
              5%




Notwithstanding
      the foregoing, the Additional Bonus for 2008 shall not be less than $150,000.
      An
      example of the manner in which the Additional Bonus shall be calculated is
      set
      forth on Attachment D to this agreement.




During
      your employment hereunder after 2008, you also will be eligible to receive
      an
      Additional Bonus based upon growth amounts
      and associated rates for future years as established no later than March 31 of each respective year by the
      Board of Directors of NYFIX
      following discussion with you .
      Net
      Revenue for this purpose shall mean the gross organic operating revenue
      generated by the Division, including commissions, net spread on securities
      lending transactions and subscription revenue, less internal charges from other
      NYFIX businesses for the subscribed services, clearing fees, third party
      execution costs, soft dollar expenses and licensing fees for algorithmic trading
      software. The
      2008
      Additional Bonus will be
      prorated for the period of time employed unless your Employment Commencement
      Date is on or before March 1, 2008.




All
      bonus
      payments (other
      than the Sign-On Bonus) shall be
      subject to your being in the employ of NYFIX on the date payment is made (unless
      you are terminated after December 31 of the applicable year without “Cause” or
      you terminate your employment following December 31 of the applicable year
      for
“Good Reason”, both as defined below, in which case any bonus earned in the
      prior applicable year shall be paid to you when bonuses are otherwise paid
      to
      other senior executives), and
      shall
      be made at the same time as bonuses are paid to other senior executives of
      NYFIX, but in no event later than March 15 of the applicable following
      year.




On
      the
      same date as the first regularly scheduled meeting of NYFIX’s Compensation
      Committee after you begin your consultancy with NYFIX (which will be February
      6,
      2008 assuming you commence your consultancy prior to that date) (the “Grant
      Date”), you
      will
      be granted an
      initial equity award of options
      to purchase the Company’s common stock: 300,000
      time based stock options, 125,000 Corporate Performance based stock options,
      and
      175,000 Division Performance based stock options; all with
      an
      exercise price equal to the closing price of the Company’s common stock on the
      Grant Date .

      not
      sooner vested and unless previously forfeited, and
      except as provided below, all
      of
      the time based stock options shall vest based on continued employment as
      follows:

      of
      the time based stock options shall vest on the first anniversary

Performance
      stock options (both Corporate and Division) will be earned and vest as
      follows:




Twenty-five
      percent (25%) will
      be
      earned (if the applicable performance measures in respect of calendar years
      2008, 2009, 2010 and 2011, respectively, are met) on each
      of March 10, 2009, March 10, 2010, March 10, 2011 and March 10, 2012. The applicable
      performance measures will be delivered to you by March 31 of each respective
      year (e.g., the Corporate and Division performance measures for the performance
      based stock options which may be earned on March 10, 2009, will be
      delivered to you by March 31, 2008),
      following discussion with you .
      Provided you are employed on the respective vesting dates, performance based
      stock options earned on March 10, 2009 will vest on March
      10,
      2010 ;
      performance based stock options earned on March 10, 2010 will vest on March
      10,
      2011; performance based stock options earned on March 10, 2011 and March 10, 2012 will
      vest
      on March 10, 2012. The Company and you understand and agree that for any year,
      based on performance achieved at the Company and/or Division level, you may
      earn
      both the Corporate and Division based performance stock options or one or the
      other of the Corporate or Division based performance stock options.




All
      performance based stock options that are unearned will be carried forward and
      may be earned and
      vested on
      March
      10, 2012 based on the achievement of specified performance measures for the
      2011

      available for earning on March 10, 2012). The performance measures used for
      this
      carry forward feature will be delivered to you by March 31, 2011,
      following discussion with you.




The
      complete terms of the
      time based and performance based stock options will be set forth in separate
      stock option agreements ,
      provided that such stock option agreements shall not contain terms or conditions
      which are inconsistent with this agreement.




You
      will
      be eligible to receive four (4) weeks of vacation each calendar
      year, which
      will be pro

      and
      benefits generally provided to other senior executives of the Company from
      time
      to time.




I
      would
      appreciate your considering our offer and advising me of your decision by January

You
      should be aware that NYFIX employees are not permitted to make any unauthorized
      use of documents or other information in their employment with NYFIX which
      could
      properly be considered or construed to be confidential or proprietary
      information of another individual or company. Likewise, NYFIX employees may
      not
      bring with them any confidential documents or other forms of tangible
      confidential information onto the premises of NYFIX relating to their prior
      employer(s)’ business.




This
      letter will also confirm that (a) you have furnished to NYFIX a copy of any
      existing employment agreements you may have with your
      current employer, and (b) except
      as
      set forth in such existing employment agreement, you
      are
      subject to no contractual or other restriction or obligation which is
      inconsistent with your accepting this offer of employment and performing your
      duties on your
      Employment Commencement Date .




As
      an
      inducement to cause NYFIX to extend this employment offer you must sign the
      accompanying documents that set forth the obligations you will have to NYFIX

      procedures that will be applicable to you ,
      all as

While
      we
      certainly hope that your employment with NYFIX will be long and mutually
      rewarding, this offer is not a guarantee of employment for a specific period
      of
      time. You should understand that you are an employee at-will, which means that

      reason) ,
      at any
      time, with or without notice. Please understand that no supervisor, manager

      employment for any specified period of time or to make any promises or
      commitments contrary to the forgoing. Further, any employment agreement entered
      into with you by the Chief Executive Officer or the Chief Financial Officer
      shall not be enforceable unless it is in a formal written agreement and signed
      by you and one of these designated company representatives. In the
      event your employment hereunder is terminated by NYFIX or you, you will be
      subject to the *Duties

      date set forth above, provided you sign a Release containing generally the
      release language attached as Attachment E to this Agreement (the “Release”) you

      participating on the date of the termination of employment for a twelve (12)
      month period, provided that, to the extent that the Company’s plans, programs
      and arrangements do not permit such continuation of your participation following
      your termination, the Company shall reimburse you the costs for COBRA coverage
      during the period referenced in subparagraph (i) above during which you are
      eligible for such coverage; (vi) other benefits, if any, in accordance with
      applicable plans, programs and arrangements of the Company; and (vii) a prorata

      shall not be less than $375,000 in total, less required withholdings) paid
      when
      bonuses are paid to other senior executives but not later than March 15 of
      the
      applicable following year. Alternatively,
      in the event you terminate your employment for Good Reason or the Company
      terminates your employment without Cause within one
      ( 1 ) year of
      a Change in Control, as defined in Attachment “A , ” you will
      receive and be provided with all of the payments and benefits set forth in

      then-current rate, less required withholdings, provided you execute
      a
      Release containing generally the release language attached as Attachment E

      this Agreement. In addition, in the event that NYFIX terminates your employment
      without Cause or you terminate your employment for Good Reason (as those terms
      are defined in the plan and grant documents) within twelve (12) months of a
      Change in Control, the terms of all Equity Awards shall be as provided in the
      applicable plan and award documents (as attached hereto), and the term of the
      non-competition provisions contained in Attachment B, subparagraph (b) shall
      be
