PURSUANT TO THE 

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 119,981 shares of Common Stock, at a price per share of $88.25 (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: 
  

			
	 Vesting Date
	  	Options Vested
	 January 15, 2016
	  	0
	 January 15, 2017

	 January 15, 2019
	  	39,972
	 January 15, 2020
	  	40,076

 To the extent that the Option has become vested and exercisable with respect to a number of shares of Common
Stock as provided above, the Option may thereafter be exercised by the Executive, in whole or in part, at any time or from time to time prior to the expiration of the Option as provided herein and in accordance with Section 6.4(d) of the Plan,
including, without limitation, by the filing of any written form of exercise notice as may be required by the Committee and payment in full of the Option Price multiplied by the number of shares of Common Stock underlying the portion of the Option
exercised. 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. Upon expiration of the Option, the Option shall be
canceled and no longer exercisable. 
 There shall be no proportionate or partial vesting in the periods prior to each vesting date and all
vesting shall occur only on the appropriate vesting date. The Committee may, in its sole discretion, provide for accelerated vesting of the Option at any time. 

(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. As a condition of the exercise of the Option, the 

  
 2 

 
Executive shall certify (or shall be deemed to have certified) at the time of exercise in a manner acceptable to the Company that the Executive is in compliance with the terms and conditions of
the Plan and that the Executive has not engaged in, and does not intend to engage in, any Detrimental Activity. In the event the Executive engages in Detrimental Activity during the one (1) year period commencing on the date any portion of the
Option is exercised or becomes vested, the Company shall be entitled to recover from the Executive at any time within one (1) year after such exercise or vesting, and the Executive shall pay over to the Company, an amount equal to any gain
realized as a result of the exercise (whether at the time of exercise or thereafter). The foregoing provisions of this Section 3(d) shall cease to apply upon a Change in Control. 

(e) Notwithstanding any other provision to the contrary in this Agreement, any unvested portion of the Option shall, upon the Executive’s
Termination, be non-exercisable and shall be canceled. 
 4. Option Term. The term of each Option shall expire on
July 15, 2020, subject to earlier termination in the event of the Executive’s Termination as specified in Section 5 below. 

5. Termination. Subject to the terms of the Plan and this Agreement, the Option, to the extent vested at the time of the
Executive’s Termination, shall remain exercisable as follows: 
 (a) In the event of the Executive’s Termination by reason of death
or Disability, the vested portion of the Option shall remain exercisable until the earlier of (i) two (2) years from the date of such Termination or (ii) the expiration of the stated term of the Option pursuant to Section 4
hereof. 
 (b) In the event of the Executive’s involuntary Termination without Cause, or the Executive’s voluntary Termination for
Good Reason, the vested portion of the Option shall remain exercisable until the expiration of the stated term of the Option pursuant to Section 4 hereof. 

(c) In the event of the Executive’s voluntary Termination without Good Reason (other than a voluntary Termination described in
Section 5(d) below), the vested portion of the Option shall remain exercisable until the earlier of (i) ninety (90) days from the date of such Termination or (ii) the expiration of the stated term of the Option pursuant to
Section 4 hereof. 
 (d) In the event of the Executive’s Termination for Cause or in the event of the Executive’s voluntary
Termination without Good Reason within ninety (90) days after an event that would be grounds for a Termination for Cause, the Executive’s entire Option (whether or not vested) shall terminate and expire upon the date of such Termination.

 6. Restriction on Transfer of Option. No part of the Option shall be Transferred
other than by will or by the laws of descent and distribution and during the lifetime of the Executive, may be exercised only by the Executive or the Executive’s guardian or legal representative. In addition, the Option shall not be assigned,
negotiated, pledged or hypothecated in any way (except as provided by law or herein), and the Option shall not be subject to execution, attachment or similar process. Upon any attempt to Transfer the Option or in the event of any levy upon the
Option by reason of any execution, attachment or similar process contrary to the provisions hereof, such transfer 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. 
 7. Rights as a Stockholder. The Executive shall have no
rights as a stockholder with respect to any shares covered by the Option unless and until the Executive has become the holder of record of the shares, and no adjustments shall be made for dividends in cash or other property, distributions or other
rights in respect of any such shares, except as otherwise specifically provided for in the Plan. 
 8. Provisions of Plan
Control. This Agreement is subject to all the terms, conditions and provisions of the Plan, including, without limitation, the amendment provisions thereof, and to such rules, regulations and interpretations relating to the Plan as may be
adopted by the Committee and as may be in effect from time to time. The Plan is incorporated herein by reference. If and to the extent that this Agreement conflicts or is inconsistent with the terms, conditions and provisions of the Plan, the Plan

PERFORMANCE SHARE AWARD AGREEMENT 

PURSUANT TO THE 

MARKETAXESS HOLDINGS INC. 

2012 INCENTIVE PLAN 

THIS PERFORMANCE SHARE AWARD AGREEMENT (this “Agreement”), made effective as of January 15, 2015, 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 (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 116,659 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”). 

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 at the Minimum, Target, Intermediate or Maximum level set forth on Appendix A during the performance period beginning on January 15, 2015 and ending on January 15,
2020 (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 a 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.

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. 

 

	 	(b)	In the event of the Participant’s Termination of Employment by the Company without Cause or by the Participant for Good Reason that in either case occurs within twelve (12) months prior to an Achievement Date,

performance metric on the applicable Achievement Date, 50% of the total number of shares of Restricted Stock corresponding to such Awarded Shares shall vest immediately and any remaining unvested shares of Restricted Stock corresponding to such
Awarded Shares shall be forfeited. 

 3.2. Change in Control. In the event of a Change in Control during the
Performance Period, if the highest price per share of Common Stock paid in the transaction related to such Change in Control equals a price per share of Common Stock under a Performance Level, as defined in and set forth on Appendix A, that
was not achieved prior to such Change in Control, 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: 

  
 -2- 

	 	(a)	The Committee may determine that one or more of the levels of achievement of the performance metric set forth on Appendix A not achieved upon or prior to the Change in Control would likely have been achieved

Control, the Participant shall be granted the applicable number of Awarded Shares set forth on Appendix A, subject to the conditions of Section 4; provided, that all unvested shares of Restricted Stock corresponding to such Awarded
Shares shall become immediately vested if (x) such Change in Control occurs within three months following a Termination of Employment by the Participant for Good Reason or (y) the Participant incurs a Termination of Employment by the
Company without Cause within 24 months following such Change in Control; 

  

	 	(ii)	Immediately prior to the Change in Control, the Committee may determine that the Performance Share Award will not be continued, assumed or have new rights substituted therefor in accordance with Section 12.1(a) of
the Plan and the Participant will be granted the applicable number of Awarded Shares set forth on Appendix A with respect to the levels of achievement of the performance metric set forth on Appendix A not achieved upon or prior to the
Change in Control that the Committee has determined would likely have been achieved during the Performance Period, and all shares of Restricted Stock corresponding to such Awarded Shares shall vest upon the Change in Control; or 

 

	 	(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.

4. Restricted Stock. 

4.1. Vesting. Any Restricted Stock issued hereunder shall become vested and cease to be Restricted Stock (but shall remain

receive and retain all regular cash dividends payable to holders of Common Stock of record on and after such Settlement Date (although such dividends will be treated, to the extent required by applicable law, as additional compensation for tax

certificates representing the Restricted Stock until such shares are no longer Restricted Stock; (ii) the Company (or its designated agent) will retain custody of the stock certificate or certificates representing the Restricted Stock and any

and (iv) the Participant shall not, directly or indirectly, Transfer the Restricted Stock in any manner whatsoever. Prior to a Settlement Date, the Participant shall have no rights as a stockholder with respect to the applicable shares of

kind required by law to be withheld with respect to any Restricted Stock which shall have become so vested, including by electing to reduce the number of shares of Common Stock otherwise deliverable to the Participant or by delivering shares of
Common Stock already owned; (ii) the Company shall, to the extent permitted by law, have the right to deduct from any payment of any kind otherwise due to the Participant any Federal, state or local taxes of any kind required by law to be
withheld with respect to any Restricted Stock which shall have become so vested, including that the Company may, but shall not be required to, sell a number of shares of Common Stock sufficient to cover applicable withholding taxes; and
(iii) in the event that the Participant does not satisfy (i) above on a timely basis, the Company may to the extent permitted by law, but shall not be required to, pay such required withholding and treat such amount as a demand loan to the
Participant at the maximum rate permitted by law, with such loan, at the Company’s 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 of the rights at law of a creditor secured by the Common Stock. The Company may hold as security any certificates representing any Common Stock and, upon demand
of the Company, the Participant shall deliver to the Company any certificates in his or her possession representing the Common Stock together with a

stock power duly endorsed in blank. The Participant also acknowledges that it is his or her sole responsibility, and not the Company’s, to file timely and properly any election under
Section 83(b) of the Code, and any corresponding provisions of state tax laws, if the Participant wishes to utilize such election. 

4.6. Legend. In the event that a certificate evidencing Restricted Stock is issued, the certificate representing the Common
Stock shall have endorsed thereon the following legends: 
  

	 	(a)	“THE ANTICIPATION, ALIENATION, ATTACHMENT, SALE, TRANSFER, ASSIGNMENT, PLEDGE, ENCUMBRANCE OR CHARGE OF THE SHARES OF STOCK REPRESENTED HEREBY ARE SUBJECT TO THE TERMS AND CONDITIONS (INCLUDING FORFEITURE) OF THE
MARKETAXESS HOLDINGS INC. (THE “COMPANY”) 2012 INCENTIVE PLAN (THE “PLAN”) AND AN AGREEMENT ENTERED INTO BETWEEN THE REGISTERED OWNER AND THE COMPANY DATED AS OF JANUARY 15, 2015. COPIES OF THE PLAN AND SUCH AGREEMENT ARE ON FILE
AT THE PRINCIPAL OFFICE OF THE COMPANY.” 

  

	 	(b)	Any legend required to be placed thereon by applicable blue sky laws of any state. Notwithstanding the foregoing, in no event shall the Company be obligated to issue a certificate representing the Restricted Stock prior
to vesting as set forth in Section 4.1 hereof. 

 5. Restrictions on Transfer. The Participant shall not
sell, negotiate, transfer, pledge, hypothecate, assign, encumber or 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. 
 6. Issuance Restrictions. The Company is not obligated to issue any securities if, in the
opinion of counsel for the Company, the issuance of such Common Stock shall constitute a violation by the Participant or the Company of any provisions of any law or of any regulations of any governmental authority or any national securities
exchange. 
 7. Securities Representations. The shares of Common Stock will be issued to the Participant and this Agreement is
being made by the Company in reliance upon the following express representations and warranties of the Participant. The Participant acknowledges, represents and warrants that: 

7.1. The Participant has been advised that the Participant may be an “affiliate” within the meaning of Rule 144 under
the Securities Act and in this connection the Company is relying in part on the Participant’s representations set forth in this section; 

  
 -7- 

 7.2. The Common Stock must be held indefinitely by the Participant unless
(i) an exemption from the registration requirements of the Securities Act is available for the resale of such Common Stock or (ii) the Company files an additional registration statement (or a “re-offer prospectus”) with regard to
the resale of such Common Stock and the Company is under no obligation to continue in effect a Form S-8 Registration Statement or to otherwise register the resale of the Common Stock (or to file a “re-offer prospectus”); 

7.3. The exemption from registration under Rule 144 will not be available under current law unless (i) a public trading
market then exists for the Common Stock, (ii) adequate information concerning the Company is then available to the public, and (iii) other terms and conditions of Rule 144 or any exemption therefrom are complied with and that any sale of
the Common Stock may be made only in limited amounts in accordance with such terms and conditions. 
 8. Not an Employment
Agreement. Neither the execution of this Agreement nor the issuance of the Performance Share Award or the Common Stock hereunder constitute an agreement by the Company to employ or to continue to employ the Participant during the entire, or
any portion of, the term of this Agreement, including but not limited to any period during which any shares of Common Stock are outstanding. 

9. Power of Attorney. The Company, its successors and assigns, is hereby appointed the attorney-in-fact, with full power of
substitution, of the Participant for the purpose of carrying out the provisions of this Agreement and taking any action and executing any instruments which such attorney-in-fact may deem necessary or advisable to accomplish the purposes hereof,
which appointment as attorney-in-fact is irrevocable and coupled with an interest. The Company, as attorney-in-fact for the Participant, may in the name and stead of the Participant, make and execute all conveyances, assignments and transfers of the
Restricted Stock, other RS Property, Common Stock and property provided for herein, and the Participant hereby ratifies and confirms that which the Company, as said attorney-in-fact, shall do by virtue hereof. Nevertheless, the Participant shall, if
so requested by the Company, execute and deliver to the Company all such instruments as may, in the judgment of the Company, be advisable for this purpose. 

10. Miscellaneous. 

10.1. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective heirs, personal legal
representatives, successors, trustees, administrators, distributees, devisees and legatees. The Company may assign to, and require, any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially
all of the business and/or assets of the Company or any affiliate by which the Participant is employed to expressly assume and agree in writing to perform this Agreement. Notwithstanding the foregoing, the Participant may not assign this Agreement
other than with respect to shares of Common Stock Transferred in compliance with the terms hereof. 

  
 -8- 

 10.2. This award of the Performance Share Award, and upon the settlement thereof the issuance of
Restricted Stock (if any), shall not affect in any way the right or power of the Board or stockholders of the Company to make or authorize an adjustment, recapitalization or other change in the capital structure or the business of the Company, any
merger or consolidation of the Company or subsidiaries, any issue of bonds, debentures, preferred or prior preference stock ahead of or affecting the Common Stock, the dissolution or liquidation of the Company, any sale or transfer of all or part of
its assets or business or any other corporate act or proceeding. 
 10.3. The Participant agrees that the award of the Performance Share
Award hereunder, and upon any settlement thereof the issuance of Restricted Stock (if any), is special incentive compensation and that the Performance Share Award and Restricted Stock (if applicable), any dividends paid thereon (even if treated as
compensation for tax purposes) and any other RS Property will not be taken into account as “salary” or “compensation” or “bonus” in determining the amount of any payment under any pension, retirement or profit-sharing
plan of the Company or any life insurance, disability or other benefit plan of the Company. 
 10.4. No modification or waiver of any of the
provisions of this Agreement shall be effective unless in writing and signed by the party against whom it is sought to be enforced. 
 10.5.
This Agreement may be executed in one or more counterparts (including via facsimile or PDF), all of which taken together shall constitute one contract. 

10.6. The failure of any party hereto at any time to require performance by another party of any provision of this Agreement shall not affect
the right of such party to require performance of that provision, and any waiver by any party of any breach of any provision of this Agreement shall not be construed as a waiver of any continuing or succeeding breach of such provision, a waiver of
the provision itself, or a waiver of any right under this Agreement. 
 10.7. The headings of the sections of this Agreement have been
inserted for convenience of reference only and shall in no way restrict or modify any of the terms or provisions hereof. 
 10.8. All
notices, consents, requests, approvals, instructions and other communications provided for herein shall be in writing and validly given or made when delivered, or on the second succeeding business day after being mailed by registered or certified
mail, whichever is earlier, to the persons entitled or required to receive the same, at the addresses set forth at the heading of this Agreement or to such other address as either party may designate by like notice. Notices to the Company shall be
addressed to the Compensation Committee of the Board with a copy to the Company’s Head of Human Resources.

shall be construed, interpreted and governed and the legal relationships of the parties determined in accordance with the internal laws of the State of Delaware without reference to rules relating to conflicts of law.

without limitation, the amendment provisions thereof, and to such rules, regulations and interpretations relating to the Plan as may be adopted by the Committee and as may be in effect from time to time. The Plan is incorporated herein by reference.

matter hereof (other than any other documents expressly contemplated herein or in the Plan) and supersedes any prior agreements between the Company and the Participant.
