MARKEL CORPORATION 2016 EQUITY INCENTIVE COMPENSATION PLAN

4.     Eligibility.

(a)     Employees. All present and future employees of Markel or a Subsidiary at the time of grant shall be eligible to receive Incentive Awards under the Plan. The Committee shall have the power and complete discretion, as provided in Section 16, to select eligible employees to receive Incentive Awards and to determine for each employee the nature of the award and the terms and conditions of each Incentive Award. The grant of an Incentive Award shall not obligate an Employer to pay an employee any particular amount of remuneration, to continue the employment of the employee after the grant or to make further grants to the employee at any time thereafter.

(b)     Outside Directors. Incentive Awards of Restricted Stock, Restricted Stock Units and Other Stock Awards consisting of “director stock” or “director units” (or other similar types of awards) (collectively, “Director Awards”) may be made to Outside Directors. The Outside Directors of the Board shall have the power and complete discretion to select Outside Directors to receive Director Awards and to determine the terms and conditions, the nature of the award and the number of shares to be allocated as part of each Director Award for each Outside Director. The grant of a Director Award shall not obligate

Markel to make further grants to the Outside Director at any time thereafter or to retain any person as a director for any period of time.

(c)     Compliance with Foreign Laws. When granting Incentive Awards to employees of a non-U.S. Subsidiary, the Committee shall have complete discretion and authority to grant such Incentive Awards in compliance with all present and future laws of the country or countries that may apply to the grant of the Incentive Award or the issuance of Company Stock under the Incentive Award. Such authorization shall extend to and includes establishing one or more separate sub-plans which include provisions not inconsistent with the Plan that comply with statutory or regulation requirements imposed by the foreign country or countries.

5.     Restricted Stock.

(a)     The Committee may make grants of Restricted Stock to employees, and the Outside Directors of the Board may make grants of Restricted Stock to Outside Directors, and in each case shall establish as to each award of Restricted Stock the terms and conditions to which the Restricted Stock is subject, including the period of time before which all restrictions shall lapse, and the Participant shall have full ownership of the Company Stock. Restricted Stock may be awarded without cash consideration.

(b)     Restricted Stock awards for employees that vest based solely on a Participant’s continued service and the passage of time shall be subject to a minimum vesting period of twelve consecutive months, and Restricted Stock awards for employees that vest based on the attainment of Performance Goals shall be subject to a minimum performance period of twelve consecutive months, provided in each case the Committee may provide for accelerated vesting upon the death, Disability, Retirement or Early Retirement of a Participant or the occurrence of a Change in Control.

(c)     Restricted Stock may not be sold, assigned, transferred, pledged, hypothecated, or otherwise encumbered or disposed of until the restrictions have lapsed or been removed. For certificated shares, certificates representing Restricted Stock shall be held by Markel until the restrictions lapse and the Participant shall provide Markel with appropriate stock powers endorsed in blank.

(d)     Restricted Stock awards for Covered Employees may be granted so as to qualify for the performance-based exception under Code Section 162(m), in which case the award shall be granted and administered in accordance with the applicable provisions of Section 7 relating to Covered Employees.

6.     Restricted Stock Units.

    

(a)     The Committee may make grants of Restricted Stock Units to employees, and the Outside Directors of the Board may make grants of Restricted Stock Units to Outside Directors, and in each case shall establish as to each award of Restricted Stock Units the terms and conditions (including vesting conditions) to which the Restricted Stock Units are subject. A Restricted Stock Unit shall entitle the Participant to receive from Markel a share of Company Stock or a cash amount equal to the Fair Market Value of the Company Stock on the date or event provided for in the applicable award agreement, subject to the vesting and other terms and conditions of the award.

(b)     Restricted Stock Unit awards for employees that vest based solely on a Participant’s continued service and the passage of time shall be subject to a minimum vesting period of twelve consecutive months, and Restricted Stock Unit awards for employees that vest based on the attainment of Performance Goals shall be subject to a minimum performance period of twelve consecutive months,

provided in each case the Committee may provide for accelerated vesting upon the death, Disability, Retirement or Early Retirement of a Participant or the occurrence of a Change in Control.

(c)     Restricted Stock Unit awards for Covered Employees may be granted so as to qualify for the performance-based exception under Code Section 162(m), in which case the award shall be granted and administered in accordance with the applicable provisions of Section 7 relating to Covered Employees.

7.     Performance Grants.

(a)     The Committee may make Performance Grants to any employee. Outside Directors shall not be eligible for Performance Grants. A Performance Grant is an award that is denominated in cash (rather than Company Stock or units of Company Stock), and which entitles a Participant to receive a payment based on the attainment of Performance Goals. Each Performance Grant shall contain the Performance Goals for the award, including the Performance Criteria (for Covered Employees) or other performance measures, the target and maximum amounts payable and such other terms and conditions of the Performance Grant. As to each Covered Employee, each Performance Grant shall be granted and administered to comply with the requirements of Code Section 162(m). The terms of a Performance Grant may be set forth in an annual or long-term bonus or incentive plan of Markel or a Subsidiary.

(b)     The Committee shall establish the Performance Goals for Performance Grants. The Committee shall determine the extent to which any Performance Criteria (for Covered Employees) or other performance measures shall be used and weighted in determining Performance Grants. The Performance Goals for any Performance Grant for a Covered Employee shall be made not later than 90 days after the start of the period for which the Performance Grant relates and shall be made before the completion of 25 percent of such period, at a time when achievement of the goal is substantially uncertain. The Committee may adjust Performance Goals as it deems necessary or appropriate during or after a performance period to reflect unusual or nonrecurring gains and losses, accounting charges or other extraordinary and unforeseen events; provided, however, the Committee may increase, but not decrease, any Performance Goal after the deadlines set forth in the preceding sentence for any Covered Employee.

(c)     Unless otherwise provided in the Performance Grant, the employee must remain continuously employed with Markel or a Subsidiary through the last day of the applicable performance period in order to be eligible to receive payment under the award; provided, however, the Committee may provide for accelerated vesting or payment of a Performance Grant upon such events as the Committee deems appropriate, including without limitation a Participant’s death, Disability, Retirement or Early Retirement or the occurrence of a Change in Control; provided further, however, the Committee shall not provide for accelerated vesting or payment upon a Covered Employee’s Retirement, Early Retirement or other termination of employment (other than due to death or Disability) unless the Performance Grant will be based on actual performance through the date of Retirement or Early Retirement or through the end of the otherwise applicable performance period.

(d)     Performance Grants may be payable in cash, shares of Company Stock or both. The Committee shall establish for each Performance Grant the amount of Company Stock or cash payable at specified levels of performance, based on the Performance Goal for each Performance Criterion (for Covered Employees) or other performance measures. The Committee shall make all determinations regarding the achievement of any Performance Goals. For Covered Employees, the Committee may not increase the amount of cash or Company Stock that would otherwise be payable upon achievement of the Performance Goal or Goals. The Committee may reduce the amount of or eliminate the any payments

otherwise due to any employee under a Performance Grant in its discretion, except as otherwise provided in the Performance Grant.

(e)     The actual payments to a Participant under a Performance Grant will be calculated by applying the achievement of the Performance Criteria (for Covered Employees) or other performance measures to the Performance Goal. The Committee shall make all calculations of actual payments and shall certify in writing the extent, if any, to which the Performance Goals have been met for a Covered Employee.

8.     Other Stock Awards. The Committee (with respect to employees) and the Outside Directors of the Board (with respect to Outside Directors) may make Other Stock Awards, granted or denominated in Company Stock or units of Company Stock, and in each case shall establish the number of shares or units of Company Stock to be awarded or to which the award is subject and the other terms and conditions applicable to each such award. Other Stock Awards may include (without limitation) the following:

(a)     “Performance shares” or “performance units” (or other similar types of awards), which are rights granted to employees to receive shares or units of Company Stock upon the attainment of Performance Goals and the satisfaction of any other terms and conditions of the award, and which shares or units may be subject to additional service-based vesting after the end of the performance period. The performance period with respect to any such award shall be at least twelve consecutive months, provided the Committee may provide for accelerated vesting upon a Participant’s death, Disability, Retirement or Early Retirement or the occurrence of a Change in Control. The Committee will make all determinations regarding the satisfaction of any Performance Goals for such an award. Any such awards for Covered Employees may be granted so as to qualify for the performance-based exception under Code Section 162(m), in which case the award shall be granted and administered in accordance with the applicable provisions of Section 7 relating to Covered Employees.

(b)     “Director stock” or “director units” (or other similar types of awards), which are shares or units of Company Stock granted to Outside Directors only, which are vested immediately on grant, but which may not be transferred by the Participant (or, in the case of units, paid to the Participant) until the Participant’s separation from service from the Board (except as necessary to satisfy the Outside Director’s tax liability in connection with the grant).

(c)     Notwithstanding the foregoing, “Other Stock Awards” shall not include stock options or stock appreciation rights, which are not authorized for issuance under the Plan.

9.     Dividend Equivalents. The Committee (with respect to employees), or the Outside Directors of the Board (with respect to Outside Directors), may provide that any Incentive Awards under the Plan earn dividends or dividend equivalents. Such dividends or dividend equivalents shall be credited to a Participant’s account, either in cash without interest or as reinvestment in additional shares or share equivalents. Any crediting of dividends or dividend equivalents shall be subject to the same restrictions and conditions as the underlying award. Except as provided by the foregoing, no Participant or Beneficiary shall have any rights as a shareholder of Markel with respect to an Incentive Award, including without limitation any rights to vote shares of Company Stock or to receive dividends or other distributions with respect thereto, unless and until he becomes the holder of record of shares of Company Stock under such award.

10.     Tax Withholding. Whenever payment under an Incentive Award is made in cash, the Employer will withhold an amount sufficient to satisfy any Applicable Withholding Taxes. Each Participant who is an employee shall agree as a condition of receiving an Incentive Award payable in the

form of Company Stock, to pay to the Employer, or make arrangements satisfactory to the Employer regarding the payment to the Employer of, Applicable Withholding Taxes. To satisfy Applicable Withholding Taxes and under procedures established by the Committee or its delegate, a Participant may elect to (i) make a cash payment or authorize additional withholding from cash compensation, or (ii) have Markel retain that number of shares of Company Stock (valued at their Fair Market Value) that would satisfy all or a specified portion of the Applicable Withholding Taxes.

11.     Transferability of Incentive Awards. Incentive Awards shall not be transferable by a Participant, except in accordance with the Participant’s will or the laws of descent and distribution or as otherwise expressly provided in the Incentive Award. If a Participant dies, any outstanding Incentive Awards that are otherwise payable to the Participant shall be paid to the Participant’s Beneficiary or, if no Beneficiary is designated, to the personal representative of the Participant’s estate or to the person to whom rights under the Incentive Award shall have passed by will or the laws of descent and distribution.

12.     Deferral Elections. The Committee (with respect to employees) and the Outside Directors of the Board (with respect to Outside Directors) may permit Participants to elect to defer the issuance of Company Stock or the settlement of awards in cash under the Plan under such rules, procedures, or programs as it may establish, in accordance with Section 409A of the Code and any other applicable laws, rules or regulations.

13.     Effective Date of the Plan. The effective date of the Plan is April 1, 2016. The Plan shall be submitted to the shareholders of Markel for approval. Until (i) the Plan has been approved by Markel’s shareholders, and (ii) the requirements of any applicable federal or state securities laws have been met, no Incentive Award shall be awarded that is not contingent on these events.

14.     Termination, Amendment. If not sooner terminated by the Board, this Plan shall terminate at the close of business on March 31, 2026. No Incentive Awards shall be made under the Plan after its termination. The Board may amend or terminate the Plan as it shall deem advisable; provided that no change shall be made that increases the total number of shares of Company Stock reserved for issuance under Incentive Awards granted under the Plan (except under Section 15), expands the types of awards under the Plan, materially expands the eligible participants or any other amendment requiring approval of Markel’s shareholders under New York Stock Exchange listing standards, Code Section 162(m) or other applicable law, unless such change is authorized by the shareholders of Markel. A termination or amendment of the Plan shall not, without the consent of the Participant, adversely affect a Participant’s rights under an Incentive Award previously granted to him.

15.     Change in Capital Structure; Other Corporate Transactions.

(a)     If there is a stock dividend, stock split or combination of shares, share exchange, recapitalization or merger in which Markel is the surviving corporation, spin-off or split-off of a Subsidiary, extraordinary dividend, or other unusual or extraordinary change in or with respect to Markel capital stock (including, but not limited to, the creation or issuance to shareholders generally of rights, options or warrants for the purchase of common stock or preferred stock of Markel), the number and kind of shares of stock or securities of Markel to be subject to the Plan and to Incentive Awards then outstanding or to be granted, the maximum number of shares or securities which may be delivered under the Plan under Sections 3(a) or 3(b), the Performance Goals and other terms of Incentive Awards and any other relevant provisions of the Plan or any Incentive Award, shall be equitably and proportionately adjusted by the Committee (with respect to employees) or the Outside Directors of the Board (with respect to Outside Directors), whose determination shall be binding on all persons. Performance Goals shall be adjusted in such a way as to preserve, to the extent possible (but not increase), the incentive level intended

under the Incentive Award. All changes under this section shall, if possible, be made in a manner that preserves the intended tax consequences of the Incentive Award under Code Sections 409A, 162(m) and any other applicable section of the Code.

(b)     If a Change in Control occurs under Section 2(e)(iii) or (iv) or if Markel is otherwise a party to a consolidation or a merger in which Markel is not the surviving entity, a transaction that results in the acquisition of substantially all of Markel’s outstanding stock by a single person or entity, or a sale or transfer of substantially all of Markel’s assets, or if a Divisive Transaction occurs with respect to a Participant’s Employer, and if the surviving entity does not agree before the occurrence of any such transaction to continue and assume the outstanding Incentive Awards under the Plan, or if the Incentive Awards would not continue for any other reason after the occurrence of such transaction, then, upon the occurrence of such transaction (or sufficiently in advance of the occurrence of such transaction if necessary or appropriate to allow the Participants to realize the intended benefits of such awards), the Committee (with respect to employees) or the Outside Directors of the Board (with respect to Outside Directors) may take such actions with respect to outstanding Incentive Awards as it deems appropriate, including without limitation providing for the immediate vesting of any such award, the removal of any restrictions with respect to any such award, or the payment or settlement of any such award in cash; provided, however, that if any such award vests or is payable subject to the attainment of Performance Goals and if the applicable performance period has not ended as of the date of such transaction, the level of attainment with respect to such goals shall be based on the actual performance achieved through the date of such transaction.

(c)     Notwithstanding subsection (b) above to the contrary, individual Incentive Awards may contain provisions with respect to vesting or payment upon the occurrence of a Change in Control or Divisive Transaction, and the terms of the Incentive Award shall govern to the extent of any inconsistency with the terms of subsection (b). Unless otherwise provided in an Incentive Award, if, within twelve months after a Change in Control, a Participant is involuntarily terminated without Cause or terminates employment for Good Reason, or upon the occurrence of a Change in Control described in Section 2(e)(iv), (i) all restrictions on Restricted Stock shall lapse, (ii) all Restricted Stock Units shall be deemed fully vested, and (iii) all Performance Grants and Other Stock Awards shall be deemed to be fully earned and vested, and each shall be immediately issued or paid as the case may be.

(d)     Notwithstanding anything in the Plan to the contrary, the Committee (with respect to employees) or the Outside Directors of the Board (with respect to Outside Directors) may take any action under this Section 15 without the consent of any Participant, and its determination shall be conclusive and binding on all persons for all purposes.

16.     Administration of the Plan.

(a)     The Committee shall administer the Plan with respect to Incentive Awards to employees and the Outside Directors of the Board shall administer the Plan with respect to Incentive Awards to Outside Directors. The Committee or the Outside Directors of the Board, as applicable (the “Administrator”), shall have general authority to impose any term, limitation or condition upon an Incentive Award that the Administrator deems appropriate to achieve the objectives of the Incentive Award. The Administrator may adopt rules and regulations for carrying out the Plan with respect to Participants. The interpretation and construction of any provision of the Plan by the Administrator shall be final and conclusive as to any Participant.

(b)     The Administrator shall have the power to amend the terms of previously granted Incentive Awards so long as the terms as amended are consistent with the terms of the Plan and provided that the

consent of the Participant is obtained with respect to any amendment that would be detrimental to him, except that such consent will not be required if such amendment is for the purpose of complying with Rule 16b-3 or any requirement of the Code applicable to the Incentive Award.

(c)     The Administrator shall have the power and complete discretion to delegate to any individual, or to any group of individuals employed by Markel or any Subsidiary, the authority to administer the Plan, including the authority to grant Incentive Awards under the Plan, consistent with applicable laws, rules and regulations (including state corporations law and the listing standards of the New York Stock Exchange) and subject to any terms and limitations of any such delegation of authority (such as limitations on the ability to grant Incentive Awards to executive officers or directors for purposes of Rule 16b-3 or to Covered Employees for purposes of Code Section 162(m)), as the Administrator deems appropriate.

17.     Recovery of Incentive Awards. If a Participant who is an employee or former employee of Markel or a Subsidiary (1) violates any restrictive covenant to which the Participant is bound by Markel or a Subsidiary in an employment agreement or otherwise, or if the Participant is not bound by such an agreement or if any such agreement does not contain such restrictive covenants: becomes associated with, recruits or solicits customers or other employees of an Employer on behalf of, or is employed by, renders services to, or owns any interest (other than any nonsubstantial interest, as determined by the Committee) in, any business that is in competition with Markel or its Subsidiaries during his or her employment with Markel or during the twelve-month period immediately following his or her termination of employment with Markel, (2) has his or her employment terminated by his Employer for Cause, or (3) engages in, or has engaged in, conduct which the Committee determines to be materially detrimental to the interests of Markel or its Subsidiaries (other than in the performance of his or her duties in good faith), the Committee may, in its sole discretion, (A) cancel all outstanding Incentive Awards of the Participant, regardless of whether then vested, (B) require the Participant to repay any payment received under an Incentive Award within the previous two years, and/or (C) offset any other amounts owed to the Participant by any payment received under an Incentive Award within the previous two years.

This section shall survive termination of the Plan.

18.     Severability. If any provision of the Plan, any Incentive Award, or any other document setting forth the terms of an award shall be held by a court of competent jurisdiction to be invalid and unenforceable, the remaining provisions of the Plan, such award or such other document shall continue in effect.
