THIS PERFORMANCE AWARD AGREEMENT (this “Agreement”) is made effective as of February 15, 2012 (the “Grant Date”), by and between MarketAxess Holdings Inc. (the “Company”) and Richard M. McVey (the “Participant”).

WHEREAS, the Board of Directors of the Company (the “Board”) adopted, and the stockholders of the Company, approved the MarketAxess Holdings Inc. 2009 Code Section 162(m) Executive Performance Incentive Plan (the “Plan”);

WHEREAS, the Company, through the Committee under the Plan, wishes to grant to the Participant as of the Grant Date a Performance Award under the Plan subject to the terms of this Agreement that will be based upon the achievement of the performance metric set forth on Appendix A attached hereto, which performance metric is intended to constitute a “performance goal”, as set forth under the Plan.

NOW, THEREFORE, the Company and the Participant agree as follows:

1. Grant of Performance Award. Subject to the restrictions, terms and conditions of the Plan and this Agreement, as of the Grant Date, the Company hereby awards to the Participant under the Plan a Performance Award with an Individual Target Award of $805,000.00. The Participant’s Individual Target Award shall be deemed invested during the Performance Period (as defined below) in 26,178 shares (the “Measurement Shares”) of the Company’s common stock, par value $.003 per share (“Common Stock”) and on December 31, 2012 (the “Adjustment Date”) the Participant’s Individual Target Award shall be adjusted to an amount equal to the cash value of the Measurement Shares based on the closing price for the Common Stock on the Adjustment Date (such adjusted amount, the “Adjusted Cash Target Award”). The number of Measurement Shares shall be subject to adjustment by the Committee during the Performance Period in the manner set forth in Section 4.2(b) of the MarketAxess Holdings Inc. 2004 Stock Incentive Plan (amended and restated effective April 28, 2006) (as amended from time to time, the “Stock Plan”).

2. Payment. Subject to the Participant’s not incurring a termination of service with the Company and its Affiliates (as defined below) prior to the Settlement Date (as defined below) (except as otherwise specifically set forth in this Agreement), during the Company’s first fiscal quarter in 2013, but in any event no later than March 15, 2013, the Committee shall certify the level of achievement of the performance metric set forth on Appendix A attached hereto with respect to the Company’s fiscal year beginning on January 1, 2012 and ending on December 31, 2012 (the “Performance Period”). The date of such certification is referred to herein as the “Settlement Date”. On the Settlement Date, the Company shall award to the Participant a Settlement Award as defined in, and in an amount determined in accordance with, Appendix A attached hereto. Subject to the terms of this Agreement, the Settlement Award shall be paid to the Participant on the Settlement Date in the form of a number of shares of Common Stock with a value (based on the closing price of the Common Stock on December 31,

2012) equal to the Settlement Award, disregarding any partial shares, such shares to be issued to the Participant as an Other Stock-Based Award under, and as defined in, the Stock Plan. No cash settlements shall be made with respect to partial shares eliminated. Pursuant to Sections 4 and 5 hereof, such shares of Common Stock, if any, shall be subject to certain restrictions, which restrictions relate to the passage of time as an employee of, or consultant to, the Company or its Affiliates, as described in Section 4.1 hereof. While such restrictions are in effect, such shares of Common Stock shall be referred to herein as “Restricted Stock.” The number of shares of Restricted Stock shall be subject to adjustment in accordance with Section 4.2(b) of the Stock Plan.

For the purposes of this Agreement, “Affiliate” means each of the following: (i) any subsidiary corporation of the Company within the meaning of Section 424(f) of the Code; (ii) any parent corporation of the Company within the meaning of Section 424(e) of the Code; (iii) any corporation, trade or business (including, without limitation, a partnership or limited liability company) which is directly or indirectly controlled 50% or more (whether by ownership of stock, assets or an equivalent ownership interest or voting interest) by the Company or one of its Affiliates; (iv) any trade or business (including, without limitation, a partnership or limited liability company) which directly or indirectly controls 50% or more (whether by ownership of stock, assets or an equivalent ownership interest or voting interest) of the Company; and (v) any other entity in which the Company or any of its Affiliates has a material equity interest and which is designated as an “Affiliate” by resolution of the Committee.

APPENDIX A

Performance Metric and Settlement Award

A. Performance Metric.

The Performance metric set forth herein is established for purposes of the grant of the Performance Award for the Performance Period and is intended to be “performance-based” under Section 162(m) of the Code.

The performance metric for the Performance Period ending December 31, 2012 shall be the Company’s attainment of pre-tax operating income of $*** per share of Common Stock before the Company’s payment of any cash bonuses to its employees for performance during the Performance Period and any expenses incurred in connection with all Performance Awards granted under the Plan and all Performance Share Awards granted under the Stock Plan for the Performance Period by the Company to employees and consultants, as set forth in the Company’s financial statements and as calculated in accordance with GAAP (the “Performance Target”). The Participant will be eligible to receive a “Settlement Award” with a value based on the level of the Performance Target achieved, as specified below. The terms and conditions governing the Performance Award will be construed and interpreted in a manner consistent with Section 162(m) of the Code and, without limiting the generality of the foregoing, the Committee will certify the attainment of the Level of Target Performance Achieved to the extent and in the manner required by Section 162(m) of the Code.

Subject to the terms and conditions of this Agreement, the value of the Settlement Award shall be determined on the Settlement Date, as follows:

Level of Target Performance Achieved	Value of the Settlement Award will be Equal to the Following Percentage of the Adjusted Cash Target Award
130% and above	150%
100%	100%
80%	50%
less than 80%	0%

B. Interpolation. In determining the value of the Settlement Award, the Committee shall interpolate the percentage of the Adjusted Cash Target Award earned for the achievement of the performance metric between each applicable target level, which percentage shall be calculated to the nearest one-hundredth percent.

C. Miscellaneous.

Notwithstanding anything to the contrary, the Committee shall calculate pre-tax operating income in a manner that excludes the following:

(i) all items of gain, loss or expense for the applicable fiscal year under consideration that are related to the disposal of a business or discontinued operations; and

A-1

(ii) all items of gain, loss or expense for the applicable fiscal year that are related to changes in accounting principles or to changes in applicable law or regulations.

In addition, the Committee may, in its sole discretion, elect to exclude from the calculation of operating income all items of gain loss or expense for the applicable fiscal year that are related to extraordinary, special, unusual or non-recurring items, events or circumstances affecting the Company or the financial statements of the Company.

With respect to the Performance Period, to the extent any provision contained herein creates impermissible discretion under Section 162(m) of the Code, such provision will be of no force or effect.

A-2
