PERFORMANCE SHARE AWARD AGREEMENT 

PURSUANT TO THE 

MARKETAXESS HOLDINGS INC. 

2012 INCENTIVE PLAN 

THIS PERFORMANCE SHARE AWARD AGREEMENT (this “Agreement”), made effective as of November 8, 2018, 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. 2012 Incentive Plan (as amended April 17, 2018, the “Plan”); 

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 on Appendix 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; 

WHEREAS, the performance metric set forth on Appendix A attached hereto is intended to constitute a “performance goal”
as set forth under the Plan; and 
 WHEREAS, such shares of Common Stock, when issued to the Participant, shall be subject to the
terms of this Agreement (including without limitation, the restrictions set forth in Sections 4 and 5 herein). 
 NOW, THEREFORE, the
Company and the Participant agree as follows: 
 1. Grant of Performance Share Award. Subject to the restrictions, terms
and conditions of the Plan and this Agreement, the Company hereby awards and grants to the Participant 19,800 Performance Shares entitling the Participant to receive, for each Performance Share earned in accordance with
Section 2 below, one share of Common Stock, subject to the provisions of Appendix A attached hereto (the “Performance Share Award”), provided that, notwithstanding anything in this Agreement,
the Plan, or any agreement between the Participant and the Company to the contrary, in the event that on or prior to January 1, 2020, (i) a Change in Control occurs, and (ii) the Participant incurs a Termination of Employment for without
Cause or for Good Reason (the “Early Trigger Event”), this Performance Share Award shall be an award with respect to 3,960 Performance Shares, and the portion of this Performance Share Award with respect to 15,840 Performance Shares
shall be deemed forfeited and canceled as of the date of such Early Trigger Event. 
 2. Payment. Within sixty (60) days
following the date of the achievement (the “Achievement Date”) of the performance metric set forth on Appendix A attached hereto during the performance period beginning on November 8, 2018 and ending on November 8,
2023 (the “Performance Period”), the Committee shall certify that such level of achievement of the performance metric has been achieved (the date of any such certification, a “Settlement Date”). Subject to the
Participant’s not incurring a Termination of Employment prior to the Settlement Date (except as otherwise specifically set forth in this Agreement), on such Settlement Date the Company shall 












 
award to the Participant the number of Awarded Shares (as defined in Appendix A) reflecting the level of attainment of the performance metric on the applicable Achievement Date as set
forth on Appendix A attached hereto. Pursuant to Sections 4 and 5 hereof, any Awarded Shares granted hereunder 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, the Awarded Shares granted subject to such restrictions shall be referred to herein as “Restricted Stock.” The Performance
Shares and, if any, the number of Awarded Shares and the number of shares of Restricted Stock are subject to adjustment under Section 4.2(b) of the Plan. The provisions in Section 9.1 of the Plan regarding Detrimental Activity shall apply
to the Performance Share Award and for such purpose the applicable Settlement Date shall be considered a vesting date with respect to the Awarded Shares awarded to the Participant on such Settlement Date.

that the Participant would have received if the Participant had been employed by the Company on such Settlement Date, based on the level of achievement of the performance metric on the applicable Achievement Date, and all Restricted Stock
corresponding to such Awarded Shares shall become immediately vested.

then on the Change in Control the Participant shall receive the Awarded Shares payable with respect to such Performance Level and all Restricted Stock corresponding to such Awarded Shares shall become immediately vested. In addition, the Committee,
in its sole discretion, may treat any then unearned Performance Shares under this Performance Share Award in accordance with any one or more of the following methods as determined by the Committee:

sole discretion and provided the Company so notifies the Participant within thirty (30) days of the making of the loan, secured by the Common Stock and any failure by the Participant to pay the loan upon demand shall entitle the Company to all

otherwise dispose of the Performance Share Award or, if any, the shares of Restricted Stock or grant any proxy with respect thereto, except as specifically permitted by the Plan and this Agreement. Any attempted Transfer in violation of this
Agreement and the Plan shall be void and of no effect and the Company shall have the right to disregard the same on its books and records and to issue “stop transfer” instructions to its transfer agent. Notwithstanding the foregoing,
nothing herein or in the Plan shall prohibit the Participant from pledging the Common Stock the Participant is granted hereunder to the Company pursuant to a stock pledge agreement entered into between the parties hereto.
