 RECITALS

 WHEREAS, the Executive is a senior management employee of Company; 

WHEREAS, the Company recognizes the value of the Executive to the Company and has determined that appropriate steps should be taken to ensure
the Company of the Executive’s continued attention and dedication to duty, and to ensure the availability of the Executive’s continued service, including in the event of a Change in Control of the Company; and 

WHEREAS, in order to fulfill the above purposes, and recognizing that the Executive shall be entitled to rely on various benefits, the
Compensation Committee of the Board of Directors of MarketAxess Holdings Inc., a Delaware corporation (“MarketAxess Holdings Inc.”) has determined that it is appropriate and in the best interests of the Company to enter into this
Agreement. 
 NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties
hereby covenant and agree as follows: 
 1. Term. The term of this Agreement (the “Term”) shall initially be for a period of five
(5) years following the Effective Date, and shall renew thereafter for successive one (1) year terms, unless the Company provides written notice to the Executive at least twelve (12) months prior to any then-applicable expiration date
of its intent not to renew this Agreement; provided, that if this Agreement is in effect at the time of a Change in Control, then the Term shall continue in perpetuity thereafter. In addition, the Term shall not terminate while any payment or
benefit obligation of the Company that is triggered hereunder shall remain outstanding. The Term shall automatically terminate upon a termination of Executive’s employment that does not entitle the Executive to the severance benefits provided
hereunder. The Restrictive Covenant Agreement (attached hereto as Exhibit B) shall survive the end of the Term and any termination of this Agreement. 
 2.
Severance Benefits Outside of the Change in Control Protection Period. If (i) the Executive’s employment is terminated by the Company without Cause prior to the effective date of a Change in Control, or (ii) if the
Executive’s employment is terminated by the Company without Cause or the Executive resigns for Good Reason, in either case, following the expiration of the CIC Protection Period (as defined below), in each case, the Company shall provide the
Executive with the following payments and benefits, in addition to the Accrued Payments:

1.0 times the sum of (A) the Executive’s Base Salary plus (B) the Executive’s Average Annual Bonus, payable in regular installments over twelve months in accordance with the Company’s general payroll practices beginning on
the first 












 
payroll date following the Release Effective Date, with the first such installment including any accrued but unpaid amounts. The amount of this severance payment shall be reduced by any
remuneration paid by the Company to the Executive in respect of the Executive’s notice of termination period and/or in lieu of such notice of termination period under and in accordance with his employment contract with the Company (the
“Employment Contract”); 
 (b) Prorated Bonus Payment; Prior Year Bonus. An amount equal to the Average Annual Bonus,
prorated based on the number of days during the year of termination that the Executive was employed prior to the Termination Date, payable in a lump sum on the first payroll date following the Release Effective Date (the “Final Year Bonus
Payment”). Such Final Year Bonus Payment shall be in consideration for any claim the Executive has or may have to any annual bonus payment from the Company under the Employment Contract in respect of the year in which his employment with
the Company terminates. In addition, to the extent not paid as of the Termination Date, the annual bonus (if any) earned by the Executive for the year immediately preceding the year in which the Termination Date occurs, determined in good faith on a
basis consistent with the Company’s annual incentive compensation program and payable at the same time as bonuses paid to senior executives of the Company, or, if later, the first payroll date following the Release Effective Date; and 

(c) Equity Vesting. With respect to any outstanding equity or equity-based incentive awards held by the Executive under any Company /
MarketAxess Holdings Inc. equity incentive plans that are not vested as of the Termination Date: (A) any such award subject solely to time- or service-based vesting shall continue to become vested, exercisable and payable on the same schedule
over the twelve (12) month period following the Termination Date as if the Executive had remained actively employed, and (B) any such award subject to performance-based vesting shall continue to become vested, exercisable and payable on
the same schedule over the twelve (12) month period following the Termination Date as if the Executive had remained actively employed (x) based on actual performance for any performance period that is completed during such twelve
(12) month period, or (y) based on target performance level for any performance period that is not completed during such twelve (12) month period. Executive’s outstanding equity awards shall otherwise be subject to the same terms
and conditions that apply under the applicable equity plan and award agreements. 
 3. Severance Benefits During the Change in Control Protection
Period. If the Executive’s employment is terminated by the Company without Cause or the Executive resigns for Good Reason, in either case during the period beginning on the effective date of a Change in Control and ending on the second
anniversary following such effective date (the “CIC Protection Period”), the Company shall provide the Executive with the following payments and benefits, in addition to the Accrued Payments: 

(a) Severance Payment. An amount equal to 1.5 times the sum of (A) the Executive’s Base Salary plus (B) the
Executive’s Average Annual Bonus, payable in a lump sum on the first payroll date following the Release Effective Date. The amount of this severance payment shall be reduced by any remuneration paid by the Company to the Executive in respect of
the Executive’s notice of termination period and/or in lieu of such notice of termination period under and in accordance with the Employment Contract;

completed prior to the Termination Date. Executive’s outstanding equity awards shall otherwise be subject to the same terms and conditions that apply under the applicable equity plan and award agreements. 

4. Termination Due to Death or Disability. If the Executive’s employment is terminated due to death or Disability, the Company shall provide the
Executive with the following payments and benefits, in addition to the Accrued Payments: 
 (a) Severance Payment. An amount
equal to 0.5 times the sum of (A) the Executive’s Base Salary plus (B) the Executive’s Average Annual Bonus, payable in a lump sum on the first payroll date following the Release Effective Date. The amount of this

Employment Contract; 
 (b) Prorated Bonus Payment; Prior Year Bonus. An amount equal to 0.5 times the Average Annual Bonus,

basis as the directors of the Company generally, which liability insurance shall at all times provide coverage in an amount that is reasonable and customary for companies of a similar size in the Company’s industry.

 EXHIBIT A 

FORM OF RELEASE AND COVENANT NOT TO SUE AGREEMENT 

THIS RELEASE AND COVENANT NOT TO SUE (this “Release Agreement”), dated as of [●], is by and between
MarketAxess Europe Limited, a company incorporated and registered in England and Wales with registered number 04017610 and with registered office 5 (10th Floor), Aldermanbury Square, London EC2V
7HR (the “Company”), and Christophe Roupie (the “Executive”). 
 RECITALS 

WHEREAS, the Company and the Executive previously entered into a Severance Protection Agreement, dated as of 31 July, 2020 (the
“Severance Agreement”); 
 WHEREAS, the Executive’s employment was terminated effective [●]; and 

WHEREAS, capitalized terms used but not defined herein shall have the meanings ascribed to them in the Severance Agreement. 

NOW, THEREFORE, in consideration of such employment and the mutual covenants and promises herein contained, and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the Company and the Executive agree as follows: 
 1. General Release and
Covenant Not to Sue. 
 (a) The Executive hereby releases the Company and all of its past, present, and future affiliates (including, but
not limited to, any Group Company) and its and their respective officers, directors, shareholders, members, employees, successors and assigns (collectively referred to herein as the “Releasees”), jointly and severally, from any and
all claims, known or unknown, which the Executive or the Executive’s heirs, successors or assigns have or may have against any Releasee arising on or prior to the Termination Date and any and all liability which any such Releasee may have to
the Executive, whether denominated claims, demands, causes of action, obligations, damages or liabilities arising from any and all bases, however denominated, including but not limited to claims for breach of contract and the Statutory Claims as set
out in Schedule 1 (the “Statutory Claims”). This release is for any and all claims, including but not limited to claims arising from and during the Executive’s employment relationship with Releasees or as a result of the
termination of such relationship. Notwithstanding any provision contained in this Release Agreement, this release is not intended to interfere with the Executive’s right to; disclose information which he is entitled to disclose under the
sections 43A and 43B of the Employment Rights Act 1996, provided that the disclosure is made in accordance with the provisions of that Act and the Executive has complied with the Company’s policy (if any) from time to time in force regarding
such disclosures; report a suspected criminal offence to the police or any law enforcement agency or co-operating with the police or any law enforcement agency regarding a criminal investigation or
prosecution; or do or say anything that is required by Her Majesty’s Revenue and Customs (“HMRC”) and/or any other relevant authority or statutory body (a “Relevant Regulator”). For the purposes of this Release
Agreement the Company, any company of which it is a Subsidiary (its holding company) and any Subsidiaries of the Company or of any such holding company and “Group” being construed accordingly (referred to herein as a “Group
Company”). 












 (b) The Executive relinquishes any right to future employment with the Company or any of the
Releasees, and agrees not to seek future re-employment with the Company or any of the Releasees. The Executive acknowledges that the Company shall have the right to refuse to
re-employ the Executive without liability of the Company or any of the Releasees. This release shall not apply to any obligation of the Company pursuant to the Severance Protection Agreement. 

(c) The Executive understands that the Executive is releasing the Releasees from claims that the Executive may not know about as of the date of
the execution of this Release Agreement, and that it is the Executive’s knowing and voluntary intent even though the Executive recognizes that someday the Executive might learn that some or all of the facts the Executive currently believes to
be true are untrue and even though the Executive might then regret having signed this Release Agreement. Nevertheless, the Executive understands that the Executive is expressly assuming that risk and agrees that this Release Agreement shall remain
effective in all respects in any such case. The Executive expressly and completely waives all rights the Executive might have under any law that is intended to protect the Executive from waiving unknown claims, and the Executive understands the
significance of doing so. 
 (d) In consideration of the terms set forth in this Release Agreement, the Executive represents that the
Executive has not filed or permitted to be filed against the Releasees any charges, complaints or lawsuits, and the Executive covenants and agrees that the Executive will not file or permit to be filed any lawsuits at any time hereafter with respect
to the subject matter of this Release Agreement and claims released pursuant to this Release Agreement (including, without limitation, any claims relating to the termination of the Executive’s employment), except as may be necessary to enforce
this Release Agreement. 
 (e) The Executive understands and agrees that nothing in this Release Agreement limits or interferes with the
Executive’s right, without notice to or authorization of the Company, to communicate in good faith with any Government Agency for the purpose of reporting a possible violation of law, or to participate in any investigation or proceeding that
may be conducted by any Government Agency, including by providing documents or other information, or for the purpose of filing a charge or complaint with a Government Agency. As used in this Release Agreement, “Government Agency”
shall mean any other self-regulatory organization or any other federal, state or local governmental agency or commission. In the event the Executive files a charge or complaint with a Government Agency, or a Government Agency asserts a claim on the
Executive’s behalf, the Executive agrees that the Executive’s release of claims in this Release Agreement shall nevertheless bar the Executive’s right (if any) to any monetary or other recovery (including reinstatement), except the
Executive does not waive: (i) the Executive’s right to receive a whistleblower award from a Government Agency for information provided to such Government Agency, (ii) any recovery to which the Executive may be entitled pursuant to
workers’ compensation and unemployment insurance laws, and (iii) any other right where a waiver is expressly prohibited by law.

 (f) Nothing in this Release Agreement shall affect the Executive’s vested rights, if
any, to the equity awarded to the Executive under the MarketAxess Holdings Inc. 2012 Incentive Plan, the MarketAxess Holdings Inc. 2020 Equity Incentive Plan, or any other equity or equity-based incentive plan of the Company or its Affiliates, in
each case, as amended or restated. The Executive’s rights to benefits under any such plan(s) will be determined in accordance with the terms of such plan(s). 

(g) Nothing in this Release Agreement shall affect the Executive’s accrued pension rights, if any, in relation to any pension plans in
which he participated by virtue of his employment with the Company. The Executive’s rights to such benefits will be determined in accordance with the terms of such plans. 

2. No Admission of Liability. It is understood that nothing in this Release Agreement is to be construed as an admission on behalf of the Releasees of
any wrongdoing with respect to the Executive, any such wrongdoing being expressly denied. 
 3. Acknowledgements.

 EXHIBIT B 

MARKETAXESS EUROPE LIMITED 

MARKETAXESS CORPORATION 

Proprietary Information and Non-Competition Agreement 

This Proprietary Information and Non-Competition Agreement (the “Agreement”) by and
between Christophe Roupie (“you”) and MarketAxess Corporation or its parent, affiliate or subsidiary by which you are employed or to which you provide services (the “Company”) is entered into as of 31 July,
2020 (the “Effective Date”). 
 1. Acknowledgments. You and the Company acknowledge that you are employed by or
otherwise provide services to the Company and/or its parents, subsidiaries and affiliates (collectively, the “Company Group”) in a capacity which creates a relationship of confidence and trust between you and the Company Group.
During the term of your employment or service relationship with the Company Group (the “Engagement Term”), you will obtain Confidential Information (as defined herein) with regard to the Company Group and its clients, customers and
vendors and will be introduced to and create or develop relationships with customers, employees, joint ventures, suppliers and other persons with which the Company Group does business. Because the Company Group will suffer substantial damage if you
engage in certain activities during or after the Engagement Term, including using or disclosing Confidential Information (as defined herein), it is necessary for the Company Group to be protected by the prohibitions and the restrictions set forth in
this Agreement in exchange for good and valuable consideration, which you acknowledge receiving. You acknowledge your agreement to the terms and conditions of this Agreement by countersigning at the end of this Agreement. 

2. Non-Disclosure of Confidential Information. During the Engagement Term and thereafter, you
(a) shall hold all Confidential Information for the benefit of the Company Group (or the owner of any Confidential Information), and (b) shall not, without the prior written consent of the Company, use for your own benefit or disclose to
any third party any Confidential Information. For the avoidance of doubt, this Section 2 is without prejudice to your obligations and the Company’s rights under clause 15 of the Employment Contract. In the event a conflict between the
provisions of this Section 2 and clause 15 of the Employment Contract, the provisions of clause 15 of the Employment Contract shall apply. 

For purposes of this Agreement, “Confidential Information” means all information obtained by or disclosed, created, revealed
or known to you as a consequence of or through your employment or other service relationship with the Company Group that is secret, confidential or not generally known to the public (other than through your disclosure of such Confidential
Information or disclosure by another person in violation of such person’s obligations to the Company Group or the owner of such Confidential Information) relating to (i) the Company Group, its businesses or operations or (ii) any
client or other third party to which the Company Group provides services or which otherwise has business dealings with the Company Group. Confidential Information includes (A) information of a commercial nature (for example, information about
customers, clients or vendors of the Company Group (or the third party or its affiliates), strategies, costs, prices and markets), (B) information of a technical nature (for example, methods, know-how, code,
processes, technical specifications, drawings and design data), 












 
(C) information of a strategic nature (for example, future developments or strategies pertaining to research and development, marketing and sales, new or improved products or services or
other matters concerning the Company Group’s or third party’s planning), information as to employees and consultants (for example, capabilities, competence, status with the Company Group and compensation levels), and (E) information
conceived, originated, discovered or developed by you during the Engagement Term. 
 In the event you are compelled by order of a court or
other governmental or legal body to disclose any Confidential Information to anyone other than the Company (and its designees), you shall promptly notify the Company of any such order and shall cooperate fully with the Company (or the owner of such
Confidential Information) in protecting such information to the fullest extent possible under applicable law. 
 Nothing in this Agreement
shall prohibit you from reporting or disclosing information under the terms of the MarketAxess “Whistleblower Policy”, a copy of which is attached hereto as Appendix A. 

3. Return of Materials. All Confidential Information, hard copy or electronic documents, records, notebooks, files, memoranda, computer
printouts, disks, computer software, designs, hardware (including but not limited to mobile devices and any network related equipment), data, reports, fee schedules or price lists, plans, communications and other documents or materials (including
copies or reproductions thereof and documents or information derived therefrom) in your possession or control (the “Materials”) prepared by you (whether individually or with others), obtained by you or disclosed to you in connection with
or relating to your employment or other service relationship with the Company Group shall be left with or returned to the Company upon the termination of the Engagement Term or upon the Company’s request. Such Materials shall at all times be
the property of the Company Group. At the request of the Company, you shall provide a signed, written certification in a form acceptable to the Company confirming that you have returned any and all Materials to the Company. For the avoidance of
doubt, this Section 3 is without prejudice to your obligations and the Company’s rights under clause 20 of the Employment Contract. 

4. Non-Competition. During the Engagement Term and for nine (9) months thereafter (the
“Non-Compete Period”), you shall not, directly or indirectly, as an individual proprietor, partner, stockholder, officer, employee, director, joint venturer, investor, lender, consultant,
contractor or in any other capacity whatsoever, provide services that are the same as or similar to any of the services that you provided to the Company Group in the twelve (12) months prior to the termination (for any reason) of your
employment by, or provision of services to, the Company Group to any person or entity: (i) that is engaged in the design, development, operation or promotion of (a) any electronic system or platform, alternative trading system, electronic
communication network or other entity that provides fixed income securities (or other fixed income instruments or derivatives) trading services, data or research products, analytical products or other services ancillary to the trading of fixed
income securities or instruments or (b) any pre- or post-trade services business for the matching, reporting or publication of securities that competes with the Company Group’s pre- or post-trade services business at the time of termination; or (ii) that is a Competing Business at the time of termination of the Engagement Term, it being understood that, for the purposes of this
Section 4 only, “Competing Business” shall 












 
mean any entity or group which derives 10% or more of its total consolidated revenues from the same or a similar product or business line as any product or business line of the Company Group that
generates 10% or more of the Company Group’s total consolidated revenues at the time of termination. Notwithstanding the foregoing, the length of the Non-Compete Period will be reduced by the period, if
any, that you remain employed by the Company but are required to remain away from work during your notice of termination period. Due to the global nature of the Company Group’s business and your global responsibilities for the Company Group,
you agree that the restrictions set forth in this Section 4 shall apply within the United States, the United Kingdom or in any foreign country where the Company Group transacts any such business or otherwise offers any such product. Nothing
herein precludes you from owning less than 1% of the total outstanding stock of a publicly held company or from engaging in any otherwise prohibited activity with the express prior written approval of the Board of Directors of MarketAxess Holdings
Inc. 
 5. Non-Solicitation. During the Engagement Term and for twelve (12) months
thereafter (the “Non-Solicitation of Customers Period”), you shall not directly or indirectly solicit, encourage or induce (or attempt to solicit, encourage or induce) any person or entity who
does business with (or is considering doing business with) the Company Group or who uses the Company Group’s products or services and to whom you provided services or about whom you obtained Confidential Information during the Engagement Term
to (a) terminate, cease, reduce, or diminish in any way its relationship or prospective relationship with the Company Group or (b) use a competing product or service. Notwithstanding the foregoing, the length of the Non-Solicitation of Customers Period will be reduced by the period, if any, that you remain employed by the Company but are required to remain away from work during your notice of termination period. 

6. Non-Solicitation of Employees or Consultants. During the Engagement Term and for twelve
(12) months thereafter (the “Non-Solicitation of Personnel Period”), you shall not directly or indirectly (a) recruit, solicit, encourage or induce (or attempt to recruit, solicit,
encourage or induce) any non-clerical employee or consultant of the Company Group (in each case with whom you had dealings during the Engagement Term) to terminate his or her employment with, or otherwise
cease or reduce his or her relationship with, the Company Group or (b) hire or assist another person or entity to hire any non-clerical employee or consultant of the Company Group or any person who, to
your knowledge, within six months before was such a person (in each case with whom you had dealings during the Engagement Term). You may however, if requested by any entity with which you are not affiliated, serve as a reference for any person who
at the time of the request is not an employee of, or consultant to, the Company Group. Notwithstanding the foregoing, the length of the Non-Solicitation of Personnel Period will be reduced by the period, if
any, that you remain employed by the Company but are required to remain away from work during your notice of termination period. For the avoidance of doubt, Sections 4, 5 and 6 supersede and replace in their entirety clause 21 of the Employment
Contract, which shall cease to have any effect on the Effective Date. 
 7. Non-Contravention.
You shall not disclose to the Company Group or use during your Engagement Term any confidential information or inventions, discoveries, concepts, improvements or innovations of any of your prior employers or of any other third party. 












 8. Representations. You acknowledge and agree that you have not entered into, and
during the Engagement Term will not enter into, any other agreement or obligation which would in any way affect, restrict or limit your employment or other service relationship with the Company Group or otherwise conflict with your obligations to
the Company Group. In addition, you hereby represent, warrant and covenant to the Company as follows: (a) you have the right to grant the rights granted in this Agreement, you are not under any contractual or other obligation that would
prevent, limit or impair, in any way, the performance of your obligations hereunder and have not done and will not do any act and have not made and will not make any grant, assignment or agreement which will or might conflict or interfere with the
complete enjoyment of all of the Company’s rights under this Agreement; and (b) all material provided or contributed by you for use in the Inventions, (i) will be wholly original with you and not copied in whole or in part from any
other work, (ii) will not violate or infringe in any way upon the rights of others, including, without limitation, any patent, copyright, trademark or other proprietary right, and (iii) will not violate any applicable law. You will defend,
indemnify and hold harmless the Company Group, and its respective managers, officers, employees and representatives, and their respective agents, successors and assigns, from and against any and all claims, losses and expenses, including without
limitation attorneys’ fees and costs, arising out of any breach or alleged breach of your representations, warranties or covenants hereunder. 

9. Enforcement. The parties have entered into this Agreement in the belief that its provisions are valid, reasonable and enforceable.

 10. Remedies. In the event of a breach or potential breach of the restrictions and prohibitions in this Agreement, you acknowledge

Information) shall be entitled to injunctive relief (in addition to its other remedies at law or equity) to have such provisions specifically enforced without posting any bond. 

11. Reasonableness. You acknowledge that the prohibitions and restrictions set forth in this Agreement, including in Sections 2, 4, 5
and 6, are reasonable and necessary for the protection of the business of the Company Group, that the restrictions and prohibitions herein will not prevent you from earning a livelihood after the termination of the Engagement Term and that part of
the compensation paid and, if you are an employee, the benefits provided to you are in consideration for entering into this Agreement. If any of the restrictions or obligations contained in this Agreement is held not to be valid or enforceable for
any reason (including on the basis that it exceeds what is reasonable for the protection of the confidential information and/or other interests of the Company) but would be valid and enforceable if part or parts of the wording were deleted then such
restriction or obligation shall apply with such deletions as may be necessary to make it valid and enforceable. 
 12. Assignment; Entire
Agreement. Your rights under this Agreement are not assignable. This Agreement and the rights hereunder shall be assignable by the Company, in whole or in part. This Agreement and the rights hereunder shall inure to the benefit of and be binding

assignees and may not be altered, modified, or amended except by written instrument signed by you and the Company. This Agreement sets forth the entire understanding of you and the Company with
regard to the subject matters covered herein and supersedes and replaces any existing agreement, written or otherwise, entered into by you and the Company with regard to the same or similar subject matter. 

13. Notices. All notices hereunder shall be given in writing and shall be either delivered personally or sent by certified or registered
mail, return receipt requested, or nationally recognized overnight courier addressed to the other party at your address on the books of the Company or at the Company’s executive offices, as the case may be. Notices shall be deemed given when
