MARKETAXESS HOLDINGS INC.

2012 INCENTIVE PLAN

STOCK OPTION AGREEMENT (“Agreement”), dated as of January 15, 2015 by and between MarketAxess Holdings Inc. (the “Company”) and Richard M. McVey (the “Executive”).

Preliminary Statement

The Board of Directors of the Company (the “Board”) or a committee appointed by the Board (the “Committee”) to administer the MarketAxess Holdings Inc. 2012 Incentive Plan (the “Plan”), has authorized this grant of an incentive stock option (the “Option”) on January 15, 2015 (the “Grant Date”) to purchase the number of shares of the Company’s common stock, par value $.003 per share (the “Common Stock”) set forth below to the Executive, as an Eligible Employee of the Company or an Affiliate (collectively, the Company and all Subsidiaries and Parents of the Company shall be referred to as the “Employer”). Unless otherwise indicated, any capitalized term used but not defined herein shall have the meaning ascribed to such term in the Plan. A copy of the Plan has been delivered to the Executive. By signing and returning this Agreement, the Executive acknowledges having received and read a copy of the Plan and agrees to comply with it, this Agreement and all applicable laws and regulations.

Accordingly, the parties hereto agree as follows:

1.Tax Matters. The Option granted hereby is intended to qualify as an “incentive stock option” under Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”). Notwithstanding the foregoing, the Option will not qualify as an “incentive stock option,” among other events, (i) if the Executive disposes of the Common Stock acquired pursuant to the Option at any time during the two (2) year period following the date of this Agreement or the one (1) year period following the date on which the Option is exercised; (ii) except in the event of the Executive’s death or disability, as defined in Section 22(e)(3) of the Code, if the Executive is not employed by the Company, any Subsidiary or any Parent at all times during the period beginning on the date of this Agreement and ending on the day three (3) months before the date of exercise of the Option; or (iii) to the extent the aggregate fair market value (determined as of the time the Option is granted) of the Common Stock subject to “incentive stock options” which become exercisable for the first time in any calendar year exceeds $100,000. To the extent that the Option does not qualify as an “incentive stock option,” it shall not affect the validity of the Option and the portion of the Option that does not qualify as an “incentive stock option” shall constitute a separate non-qualified stock option.

2.Grant of Option. Subject in all respects to the Plan and the terms and conditions set forth herein and therein, the Executive is hereby granted an Option to purchase from the Company [•]¹ shares of Common Stock, at a price per share of $[•]² (the “Option Price”).

3.Exercise. (a) Except as set forth in subsections (b) through (e) below, the Option shall vest and become exercisable as follows, provided that the Executive has not incurred a Termination of Employment prior to the vesting date:

Payment of the Option Price may be made by any method provided under Section 6.4(d) of the Plan, including, without limitation, (i) solely to the extent permitted by applicable law, if the Common Stock is traded on a national securities exchange or quoted on a national quotation system sponsored by the Financial Industry Regulatory Authority, through a procedure whereby the Executive delivers irrevocable instructions to a broker reasonably acceptable to the Committee to deliver promptly to the Company an amount equal to the Option Price or (ii) the relinquishment of a portion of the Option based on the Fair Market Value of the Common Stock on the payment date.

(b) Upon the death or Disability of the Executive, fifty percent (50%) of the then unvested portion the Option shall become fully vested and exercisable on the date of the Executive’s death or Disability.

(c) Upon the Executive’s Termination (i) by the Company without Cause, or (ii) by the Executive for Good Reason, one hundred percent (100%) of the then unvested portion the Option shall become fully vested and exercisable on the date of such Termination.

(d) In the event that the Executive engages in Detrimental Activity(as defined in Exhibit A hereto) prior to any exercise of the Option, the Option shall thereupon terminate and expire.

WHEREAS, the Company, through the Committee under the Plan, wishes to grant to the Participant a Performance Share Award under the Plan that, upon the achievement of the performance metric set forth onAppendix A attached hereto and subject to the Participant’s continuing service with the Company or an Affiliate, may provide for the issuance of shares of the Company’s common stock, par value $.003 per share (“Common Stock”) in accordance with the terms of this Agreement;

(iii) Immediately prior to the Change in Control, the Committee may determine that the Performance Share Award will be continued, assumed or have new rights substituted therefor in accordance with Section 12.1(a) of the Plan.

(b) The Committee may determine that one or more of the levels of achievement of the performance metric set forth onAppendix A not achieved upon or prior to the Change in Control would likely not have been achieved during the Performance Period and treat all or a portion of the Performance Share Award in accordance with any one of the following methods as determined by the Committee:

(i) Immediately prior to the Change in Control, the Committee may determine the applicable number of Awarded Shares set forth onAppendix A with respect to a level of achievement of the performance metric set forth onAppendix A not achieved upon or prior to the Change in Control that the Committee has determined would likely not have been achieved during the Performance Period will be canceled in their entirety; or

-21-
