12       DIRECTORSHIPS

12.1     Your office as a director of any Group Company (if any) is subject to
         the Articles of Association of the relevant company (as amended from
         time to time). If the provisions of this agreement conflict with the
         provisions of the Articles of Association, the Articles of Association
         will prevail.

12.2     You must resign from any office held in any Group Company if you are
         asked to do so by the Company.

12.3     If you do not resign as an officer of a Group Company, having been
         requested to do so in accordance with clause 12.2, the Company will be
         appointed as your attorney to effect your resignation. By entering into
         this agreement you irrevocably appoint the Company as your attorney to
         act on your behalf to execute any document or, to do anything in your
         name necessary to effect your resignation in accordance with clause
         12.2. If there is any doubt as to whether such a document (or other
         thing) has been carried out within the authority conferred by this
         clause 12.3, a certificate in writing (signed by any director or the
         secretary of the Company) will be sufficient to prove that the act or
         thing (in the absence of any manifest error) falls within that
         authority.

12.4     The termination of any directorship or other office held by you will
         not terminate your employment or amount to a breach of terms of this
         agreement by the Company.

12.5     During your Employment, should you be appointed a director of a Group
         Company, you will not do anything which could knowingly cause you to be
         disqualified from continuing to act as a director of that Company.

         During your Employment, you must not resign your office as a director
         of any Group Company without the agreement of the Company, such consent
         not to be unreasonably withheld.

13.1     The leave year runs from 1 January to 31 December.

13.2     You are entitled to 25 days' paid holiday in each leave year ("holiday
         entitlement"), accruing on a daily basis. This will be pro-rated in the
         year of joining and leaving the Company and the resulting entitlement
         will be rounded up to the nearest whole day. Any holiday entitlement
         not used in a holiday year will be forfeited.

13.3     You must agree the dates of your holidays in advance with your manager.
         You agree that the provisions of Regulations 15(1) to (4) of the
         Regulations (dates on which leave is taken) do not apply to your
         employment.

13.4     You are also entitled to English bank and public holidays with pay.

13.5     On termination of employment you will be paid in respect of holiday
         entitlement not taken. If you have taken holidays in excess of your
         entitlement at the termination date, the Company may deduct from your
         final salary an amount that is equal to one two hundred and sixtieth of
         your gross salary payable under clause 9.1 multiplied by the number of
         excess days of holiday taken.

14       OTHER BENEFITS

14.1     PRIVATE MEDICAL INSURANCE

         disclose the results of the examination to the Company provided that

         continue to pay your base salary (as defined in clause 9.1) for a total
         period of 3 months (whether consecutive or otherwise) out of any 12
         month period. Any payment of salary is inclusive of Statutory Sick Pay
         and is subject to the provision of appropriate supporting medical
         documentation, as reasonably required by the Company.

                  which the Company or any Group Company had taken Demonstrable
                  Steps, and in respect of which you had access to confidential

         notice given by the Company or you (less any deductions the Company is
         required by law to make). The Company may pay such sum as a lump sum at
         the later of seven days of the termination of employment or the next
         scheduled payroll date or, in equal monthly instalments payable on the

         work performance, the Company may move you to suitable alternative
         work, if this is available.

                             Re: Terms of Employment

Dear John:

                  The purpose of this letter is to confirm that Market Axess
Inc. (the "Company") has offered you a position as Director Applications
Development, subject to the terms of this letter (the "Letter Agreement"). Your
employment will commence on the closing date of the transaction contemplated by
the Agreement and Plan of Merger (the "Merger Agreement") between the Company,
Trading Edge, Inc. ("Edge") and such other entities listed in the Merger
Agreement (the "Commencement Date") and will continue until such employment is
terminated by you or the Company. Notwithstanding anything else herein, your
employment with the Company will be "at-will" and you and the Company retain the
right to terminate your employment hereunder at any time for any reason or no
reason or by mutual agreement. You will report to Rachel Moseley, Chief
Information Officer of the Company.

                  While you are employed by the Company, you will devote all of
your business time and efforts to the performance of your duties hereunder and
use your best efforts in such endeavors.

                  While you are employed by the Company, the Company will pay
you a base salary at the rate of not less than $225,000 per year, in accordance
with the usual payroll practices of the Company. If you are employed by the
Company at the end of the fourth, eighth and twelfth months following the
Commencement Date, you will receive a retention bonus in the amount of $25,000
on each such date. In the event you are employed by the Company through and on
December 31, 2001 you will receive a discretionary performance bonus for the
applicable year which is expected to range from $25,000 to $75,000, depending

on your performance. Any earned and accrued bonus will be paid to you when other
employee bonuses are paid.

                  On the Commencement Date, the Company will award you stock
options to purchase 10,000 shares of the Company's common stock (the "Stock
Options") in accordance with the terms of the Market Axess Inc. 2000 Stock
Incentive Plan. The exercise price of the Stock Options shall be the fair market
value of the Company's common stock on the date of grant. The Stock Options
shall vest over a two (2) year period as follows: fifty percent (50%) of the
Stock Options shall vest on the one (1) year anniversary of the Commencement
Date and fifty percent (50%) of the Stock Options shall vest on the two (2) year
anniversary of the Commencement Date, provided you are employed by the Company
on each applicable vesting date.

                  It is expected that you will continue to participate in the
Trading Edge, Inc. benefit plans and programs for three (3) to six (6) months
after the Commencement Date. Thereafter, you will be entitled to participate, to
the extent eligible thereunder, in all Company benefit plans and programs, in
accordance with the terms thereof in effect from time to time, as are provided
by the Company to other employees of a comparable level of employment.

                  Upon presentation of appropriate documentation, you will be
reimbursed by the Company for reasonable business expenses, in accordance with
Company policies, in connection with the performance of your duties hereunder.

                  In the event your employment with the Company pursuant to this
Letter Agreement is terminated other than (x) by you voluntarily, (y) as the
result of your death, or (z) by the Company as the result of (A) your willful
misconduct in the performance of your duties under this Letter Agreement, (B)
gross negligence in the performance of your duties under this Letter Agreement
which has a material adverse effect on the business or assets of the Company or
its affiliates, (C) your conviction of, or plea of guilty or nolo contendere to,
a crime relating to the Company or any affiliate or any felony or (D) your
consistent and habitual failure to perform your duties (a "Disqualifying
Event"), and subject to your execution of a waiver and general release
substantially in the form which has been provided to other employees of the
Company, the Company will (i) continue to pay you your base salary for a period
of six (6) months following the date of such termination of employment, at such
times as base salary is paid to employees of the Company, but off the employee
payroll, and (ii) continue health care coverage under the Company's health care
plan in accordance with its terms and, pay your employee health care premium
contributions for a period of no more than six (6) months.

the details of which will be provided to you when you qualify. You will be under
no obligation to seek other employment and there will be no offset against any
amounts owing to you under this paragraph on account of any remuneration
attributable to any subsequent employment that you may obtain.

                  Upon termination of your employment for any reason, the
Company will have no obligations under this Letter Agreement other than: (i) as
provided above and (ii) to pay you: (x) any base salary that you have earned
and/or bonus you have earned (by remaining employed on and through December 31),
but remains unpaid; (y) any unreimbursed business expenses otherwise
reimbursable in accordance with the Company's policies as in effect from time to
time and (z) benefits in accordance with the terms of the applicable plans and
programs of the Company.

                  You will be required to execute a confidential information,
intellectual property, and noncompetition agreement (the "Noncompetition
Agreement"), substantially identical to that which the Company requires of other
employees of the Company, simultaneously with, or prior to the Commencement
Date.

                  You represent that your execution and performance of this
Letter Agreement will not be in violation of any other agreement to which you
are a party. Notwithstanding anything else herein, this Letter Agreement is
personal to you and neither the Letter Agreement nor any rights hereunder may be
assigned by you. The Company may assign the Letter Agreement to any parent or
subsidiary or acquiror of all or substantially all of the assets of the Company.
This Letter Agreement shall inure to the benefit of and be binding upon the
personal or legal representatives, executors, administrators, successors, heirs,
distributees, devisees, legatees and permitted assignees of the parties.

                  You agree that all disputes and controversies arising under or
in connection with this Letter Agreement or Noncompetition Agreement, other than
seeking injunctive or other equitable relief under the Noncompetition Agreement,
shall be settled by arbitration conducted before one (1) arbitrator sitting in
New York City, or such other location agreed to by you and the Company, in
accordance with the National Rules for the Resolution of Employment Disputes of
the American Arbitration Association then in effect. The determination of the
arbitrator shall be final and binding on you and the Company. Judgement may be
entered on the award of the arbitrator in any court having proper jurisdiction.
Each party shall bear their own expenses of such arbitration.
