13.Modification and Waiver.

14.Benefit and Assignment. All of the terms of this Agreement shall be binding upon, inure to the benefit of and be enforceable by the Company and its subsidiaries, affiliates, successors and assigns and by the Executive and the Executive's heirs and personal representatives. The Company (or any successor or assign) may assign this Agreement to any subsidiary or affiliate or any person which, whether by merger, purchase, or otherwise, acquires all or substantially all of the assets, stock or business of the Company or of any discrete portion thereof.

APPENDIX B — INTELLECTUAL PROPERTY DEED

As a material part of the consideration for my employment by Markel International Services Limited ("Company"), the compensation that I, Simon Wilson, shall receive during my employment, and the additional consideration that I will receive pursuant to the Employment Agreement to which this Intellectual Property Deed ("IP Agreement") is attached as Exhibit A, I acknowledge and agree that, by my signature below, I also agree to this IP Agreement's terms, which are deemed incorporated into and a part of the Employment Agreement:

1.(a) Company owns the sole and exclusive right, title and interest in and to any and all Works (as defined below), including without limitation any and all source code or other intellectual property and further including without limitation all copyrights, trademarks, service marks, trade names, slogans, patents, ideas, designs, concepts and other proprietary rights. Company's right, title and interest in and to the Works includes without limitation the sole and exclusive right to secure and own copyrights and maintain renewals throughout the world, and the right to modify and create derivative works of or from the Works without any payment of any kind to me. To the extent that any of the Works do not accrue to Company, my signature on the Employment Agreement constitutes an assignment (without any further consideration) to Company of any and all of my respective copyrights and other rights, title and interest in and to all Works. I will disclose promptly to Company all Works, whether or not they are patentable, copyrightable or subject to trade secret protection.

(b) I will provide any assistance reasonably requested by Company to obtain applicable letters patent and copyright registrations covering inventions, original works of authorship and other Works belonging or assigned hereunder to Company. I will execute any transfers of ownership of letters patent or assignments of copyrights or other proprietary rights transferred or assigned hereunder. I understand that my obligations under this Section 1(b) shall survive any termination of this IP Agreement or of my employment by Company in perpetuity; provided that Company

will compensate me at a reasonable rate for time actually spent performing such obligations at Company's request after any such termination. If Company is unable for any reason whatsoever, including my mental or physical incapacity, to secure my signature to apply for or to pursue any application for any applicable letters patent or copyright registrations or on any document transferring or assigning any patent, copyright or other proprietary right that I am obligated hereunder to transfer or assign, I hereby irrevocably designate and appoint Company and its duly authorized officers and agents as my agent and attorney in fact, to act for and on my behalf and in my stead to execute and file any such applications and documents and to do all other lawfully permitted acts to further the prosecution and issuance of letters patent or copyright registrations or transfers or assignments thereof or of any other proprietary rights with the same legal force and effect as if executed by me. This appointment is coupled with an interest in and to the inventions, works of authorship, trade secrets and other Works to which any proprietary rights may apply and shall survive my death or disability.

(c) As used in this IP Agreement, "Works" means (i) any inventions, developments, improvements, trade secrets, ideas or original works of authorship that I conceive, create, develop, discover, make, acquire or reduce to practice in whole or in part, either solely or jointly with another or others, during or pursuant to the course of my employment by Company and that relate to Company or any of its subsidiaries or affiliates or their respective businesses, or to Company's or any of its subsidiaries' or affiliates' actual or

demonstrably anticipated research or development, (ii) any inventions, developments, improvements, trade secrets, ideas or original works of authorship that I conceive, create, develop, discover, make, acquire or reduce to practice in whole or in part, either solely or jointly with another or others, during or pursuant to the course of my employment by Company and that are made through the use of any of Company's or any of its subsidiaries' or affiliates' equipment, facilities, supplies, trade secrets or time, or that result from any work performed for Company or any of its subsidiaries or affiliates, and (iii) any part or aspect of any of the foregoing.

2. I hereby waive irrevocably all moral rights (as defined in Chapter IV of Part I of the Copyright, Designs and Patents Act 1988, and all similar rights in other jurisdictions to the extent permitted in the relevant jurisdiction) in any Works.

3. I have been notified by Company, and understand, that the foregoing provisions of Section 1 do not apply to an invention for which no equipment, supplies, facilities or trade secret information of Company or any of its subsidiaries or affiliates was used and which was developed entirely on my own time, unless: (a) the invention relates (i) to the business of Company or any of its subsidiaries or affiliates or (ii) to Company's or any of its subsidiaries' or affiliates' actual or demonstrably anticipated research and development, or (b) the invention results from any work performed by me for Company or any of its subsidiaries or affiliates.

(j)comply with any law applicable to the business of the Company, any Group Company or your employment.

2.1 Your prior service with the Company and its affiliates is recognised for statutory purposes. Accordingly, your period of continuous employment began on 4 February 2010.

10.2In the respective holiday years in which your employment commences or terminates, your holiday entitlement will be calculated on a pro rata basis by reference to your annual entitlement.

10.3All holiday requests must be approved in writing in advance. The Company may require you to take (or not to take) holiday days on particular dates, including during your notice period.

On such termination the Company shall pay you in lieu of any accrued but untaken holiday entitlement for the holiday year in which termination takes place and any untaken days permitted to be carried forward from the preceding holiday year. The amount of the payment in lieu will be calculated as 1/260th of your annual equivalent salary for each untaken day of the entitlement.

10.6If on termination of your employment you have taken more holiday than your accrued holiday entitlement, the Company shall be entitled to deduct the excess holiday pay from any payments due to you calculated at 1/260th of your annual equivalent salary for each excess day for full time employees. For part time employees, the amount deducted will be calculated using the hourly pay rate.

10.7 You may be eligible to take the following types of paid leave, subject to any statutory eligibility requirements or conditions and the Company's rules applicable to each type of leave in force from time to time:

(a)statutory maternity leave and you may be eligible to receive Company maternity pay subject to the rules set out in the Company's maternity leave policy from time to time;

12.1 The Company takes a zero-tolerance approach to tax evasion. You must not engage in any form of facilitating tax evasion, whether under UK law or under the law of any foreign country. You must immediately report to the Compliance business unit any request or demand from a third party to facilitate the evasion of tax or any concerns that such a request or demand may have been made. You must at all times comply with our relevant policies, available on MyMarkel and may be updated from time to time.

12.2 You must comply with any local regulatory requirements, applicable to your Role from time to time, including but not limited to Solvency II/SMCR.

12.3 You will be informed if your Role currently includes or evolves to include the performance of a Senior Manager and / or Certification function under the Senior Manager and Certification Regime (SM&CR) or any replacement, re-enactment and / or equivalent of such regime or directive as required by the Company’s regulatory bodies. In this event, you shall agree to the terms of an SMCR Schedule to this Agreement which shall (save where expressly indicated otherwise within the Schedule) also form part of your terms and conditions of employment with the Company. In the event that your Role and duties under this Agreement change at any time to include performance of a different function under the SM&CR, you agree to enter into and be bound by the terms of a revised and updated SMCR Schedule to take account of your new Role and prescribed responsibilities. For the avoidance of doubt, your rights and obligations set out in any SMCR Schedule are in addition to your rights and obligations set out in the main body of this Agreement. In the event that there is any conflict between the terms of the main body of this Agreement and any SMCR Schedule the terms of the SMCR Schedule shall take precedence.

12.4 During your employment you must complete the training requirements which will be paid for by the Company. You shall be entitled to take part in various training courses which we may provide from time to time in-house or externally. The Company is committed to supporting employees with training and development needs.

13.Termination of contract

13.1Subject to clause 13.5, the Company may in its sole and absolute discretion (for any reason or no reason), following the giving of notice in writing, terminate your employment at any time with immediate effect in accordance with the provisions of clause 13.2.

13.2If the Company makes an election under clause 13.1 it shall pay to you the Base Salary (subject to deductions required by law) that would have otherwise accrued to you during your notice period (or balance thereof) (“Payment in Lieu of Notice”) and for the purpose of calculating the Payment in Lieu of Notice, no account shall be taken of any benefits, commission, bonus or holiday entitlement that would have accrued during your notice period (or balance thereof). The Company may pay the Payment in Lieu of Notice in equal monthly instalments until the notice period (or balance thereof) would have expired had notice been given. Any Payment in Lieu of Notice shall be offset against any severance due to you in accordance with the Executive Employment Agreement.

13.3In the event that you leave the Company (for whatever reason) and owe the Company monies, the monies will be recouped by the Payroll team from your final salary or any sums due to you on the termination of your employment in accordance with the Executive Employment Agreement in accordance with your express agreement to make these deductions under clause 6.4 of this Agreement.

13.4During any period of notice of termination, whether given by the Company or by you, the Company is under no obligation to assign any duties to you and shall be entitled to exclude you from its premises, provided that this does not affect your entitlement to receive salary and other contractual benefits, subject always to the rules of any relevant scheme or policy (Garden Leave). Any Base Salary paid to you during your Garden Leave will be offset against any severance due to you in accordance with the Executive Employment Agreement. If the Company exercises its right to place you on Garden Leave, you shall continue to be bound by the same obligations as were owed to the Company prior to the commencement of the Notice Period, except the obligation to work. Holidays outstanding at the commencement of Garden Leave must be taken during the period of Garden Leave and any holidays accrued during a period of Garden Leave will be deemed to have been taken during that same period.

13.5The Company may by written notice to you, terminate your Employment at any time if you commit a Cause event, in accordance with the provisions of the Executive Employment Agreement.

14.Obligations on termination
