The period between beginning on January 1, 2023, and ending on December 31, 2025 shall be the “Performance Period.”

Upon vesting, the Restricted Stock Units shall become payable in cash in an amount equal to the product of (i) the average Fair Market Value of the Common Stock for the 15 trading days preceding the Vesting Date and (ii) the number of Restricted Stock Units vesting on the Vesting Date (subject to Section 5 below).

b.Effect of Termination of Employment.

i.Except as provided in Section 2(b)(ii), 2(b)(iii) and 2(d), upon your termination of employment with Capital One for any reason all Restricted Stock Units shall immediately be forfeited (to the extent not previously vested or forfeited as provided herein).

ii.Upon your termination of employment with Capital One as a result of your death or Disability, the Restricted Stock Units shall immediately vest, the date of such death or Disability shall be the Vesting Date and the cash shall become payable in full as

described in Section 2(a) (to the extent not previously vested or forfeited as provided herein).

iii.Upon your termination of employment with Capital One as a result of Retirement, the Restricted Stock Units shall continue to vest on the Vesting Date (to the extent not previously vested or forfeited as provided herein) and remain subject to reduction pursuant to Sections 12(a) and 12(b).

c.Vesting Schedule Upon Becoming Subject to Withholding.

i.Unless otherwise determined by the Committee or the independent members of the board of directors of the Company (the “Board”), as applicable, and to the extent permitted or required by law, Capital One may determine, in its sole discretion, (A) that you have become subject to withholding under applicable tax laws at a time when Restricted Stock Units are not otherwise vesting pursuant to this Section 2, and (B) that a portion of the Restricted Stock Units shall vest and become payable, only and to the extent sufficient on the date of such determination (the “Determination Date”), to provide for the payment of any tax liability in accordance with applicable tax laws, in an amount equal to the product of (i) the Fair Market Value of the Common Stock for the Determination Date and (ii) the number of Restricted Stock Units vesting on the Determination Date. The number of Restricted Stock Units vesting pursuant to the preceding sentence shall be rounded up to the nearest whole Restricted Stock Unit. It is understood that the remaining portion of the Restricted Stock Units shall continue to vest on the Vesting Date as provided herein (to the extent not previously vested or forfeited as provided herein).

ii.Notwithstanding any other provision of this Agreement to the contrary, Capital One will take all necessary steps to withhold the amount determined in accordance with the immediately foregoing paragraph in satisfaction of any applicable tax withholding liability, unless Capital One makes another method of payment available to you.

d.Effect of Change of Control. Upon your termination of employment by Capital One without Cause or by you for Good Reason (each as defined below), in either case on or prior to the second anniversary of the occurrence of a Change of Control of Capital One, then, notwithstanding anything herein to the contrary, the Restricted Stock Units (as may be adjusted in accordance with Section 4.4 of the Plan) shall vest, the date of such termination shall be the Vesting Date and the Restricted Stock Units shall become payable in cash as described in Section 2(a) immediately following the occurrence of your termination of employment following such Change of Control (to the extent not previously vested or forfeited as provided herein); provided, however, that if the Restricted Stock Units are considered deferred compensation under Section 409A of the Code and not exempt from Section 409A of the Code as a short-term deferral or otherwise, and you are a “specified employee,” as defined in and pursuant to Reg. Section 1.409A 1(i) or any successor regulation, on the date of any such termination of employment without Cause or for Good Reason, you will not be entitled to such vesting prior to the earlier of (i) the date which is six months from the date of your “separation from service” (as defined in Reg. Section 1.409A 1(h) or any successor regulation) as a result of such termination and (ii) your death.

e.Definitions.

i.For purposes of this Agreement, “Cause” shall mean (1) the willful and continued failure to perform substantially your duties with the Company or any Affiliate (other than

any such failure resulting from incapacity due to physical or mental illness or following your delivery of a Notice of Termination (as defined below) for Good Reason), after a written demand for substantial performance is delivered to you by the Board or the Committee that specifically identifies the manner in which the Board or Committee believes that you have not substantially performed your duties, or (2) the willful engaging by you in illegal conduct or gross misconduct that is materially and demonstrably injurious to the Company. No act, or failure to act, on your part shall be considered “willful” unless it is done, or omitted to be done, by you in bad faith or without reasonable belief that your action or omission was in the best interests of the Company. Any act, or failure to act, based upon (A) authority given pursuant to a resolution duly adopted by the Board, or if the Company is not the ultimate parent corporation of the Employer and is not publicly-traded, the board of directors (or equivalent management body) of the ultimate parent of the Employer (the “Applicable Board”) or (B) the advice of counsel for the Company shall be conclusively presumed to be done, or omitted to be done, by you in good faith and in the best interests of the Company. The cessation of your employment shall not be deemed to be for Cause unless and until there shall have been delivered to you a copy of a resolution duly adopted by the affirmative vote of not less than three-quarters of the entire membership of the Applicable Board (excluding you, if you are a member of the Applicable Board) at a meeting of the Applicable Board called and held for such purpose (after reasonable notice is provided to you and you are given an opportunity, together with your counsel, to be heard before the Applicable Board), finding that, in the good faith opinion of the Applicable Board, you are guilty of the conduct described in this Section 2(e)(i), and specifying the particulars thereof in detail.

ii.For purposes of this Agreement, “Good Reason” shall mean (1) the assignment to you of any duties inconsistent in any respect with your position (including status, offices, titles and reporting requirements), authority, duties or responsibilities, or any action by the Company that results in a diminution in such position, authority, duties or responsibilities, excluding for this purpose an isolated, insubstantial and inadvertent action not taken in bad faith and that is remedied by the Company promptly after receipt of notice thereof given by you; (2) any failure by the Company to pay your compensation owed other than an isolated, insubstantial and inadvertent failure not occurring in bad faith and that is remedied by the Company promptly after receipt of notice thereof given by you; (3) the Company’s requiring you (I) to be based at any office or location more than 35 miles from the office or location at which you were required to work as of the date of this Agreement or (II) to travel on Company business to a substantially greater extent than required during the 120-day period immediately prior to the date the Change of Control occurs; or (4) any other action or inaction that constitutes a material breach by the Company of this Agreement or any employment agreement. For purposes of this Section 2(e)(ii) of this Agreement, any good faith determination of Good Reason made by you shall be conclusive.Your mental or physical incapacity following the occurrence of an event described above in clauses (1) through (4) shall not affect your ability to terminate employment for Good Reason.

iii.Any termination by the Company for Cause, or by you for Good Reason, shall be communicated by Notice of Termination to the other party. “Notice of Termination” means a written notice that (1) indicates the specific termination provision in this Agreement relied upon, (2) to the extent applicable, sets forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of your employment under the provision so indicated, and (3) if the Date of Termination (as defined herein) is other than the date of receipt of such notice, specifies the Date of Termination (which Date of Termination shall be not more than 30 days after the giving of such notice). The

failure by you or the Company to set forth in the Notice of Termination any fact or circumstance that contributes to a showing of Good Reason or Cause shall not waive any right of you or the Company, respectively, hereunder or preclude you or the Company, respectively, from asserting such fact or circumstance in enforcing your or the Company’s respective rights hereunder.

iv.“Date of Termination” means, if your employment is terminated by the Company for Cause, or by you for Good Reason, the date of receipt of the Notice of Termination or such later date specified in the Notice of Termination, as the case may be. You and the Company shall take all steps necessary to ensure that any termination described in this Section 2(e) constitutes a “separation from service” within the meaning of Section 409A of the Code, and notwithstanding anything contained herein to the contrary, the date on which such separation from service takes place shall be the “Date of Termination.”

3.Non-Transferability. Subject to the provisions of Section 2 hereof, the rights represented by the Restricted Stock Units shall not be assignable or transferable, or otherwise alienated or hypothecated, under any circumstances. Any purported or attempted transfer of such units or such rights shall be null and void and shall result in the immediate forfeiture and cancellation of the Restricted Stock Units.

4.Modification and Waiver. Except as provided in the Plan with respect to determinations of the Board or the Committee and subject to the Committee’s right to amend the Plan, neither this Agreement nor any provision hereof can be changed, modified, amended, discharged, terminated or waived orally or by any course of dealing or purported course of dealing, but only by an agreement in writing signed by you and Capital One; provided that, changes, modifications and amendments not detrimental to you may be made in writing signed only by Capital One. No such agreement shall extend to or affect any provision of this Agreement not expressly changed, modified, amended, discharged, terminated or waived or impair any right consequent on such a provision. The waiver of or failure to enforce any breach of this Agreement shall not be deemed to be a waiver or acquiescence in any other breach thereof.

5.Tax Withholding. If you become subject to withholding under applicable tax laws other than as described in Section 2(c), you agree to pay Capital One the amount required to be withheld by one or more of the following methods:

a.automatically through payroll withholding; or

b.by such other methods as Capital One may make available from time to time.

6.Dividend Equivalents. With respect to the Restricted Stock Units, you shall be credited with dividend equivalents as and when dividends are paid to holders of shares of the Company’s Common Stock. By accepting this Award, you agree that such dividend equivalents shall accumulate and be paid to you in cash (without interest) as and when you receive payment under Section 2 with respect to the Restricted Stock Units from which such dividend equivalents are derived. You further agree that all such dividend equivalents shall be subject to the same vesting requirements that apply to the Restricted Stock Units from which such dividend equivalents are derived.

7.Governing Law. This Agreement shall be governed by United States federal law and, to the extent not preempted thereby, by the laws of the State of Delaware. Capital One and you hereby consent and submit to the personal jurisdiction and venue of any state or federal court located in any city or county of Delaware for resolution of any and all claims, causes of action or disputes arising out of this Agreement. You and Capital One agree that the court shall not set aside the Committee’s determinations unless there is clear and convincing evidence of bad faith or fraud.

8.Conflicts. In the event of any conflict between the provisions of the Plan as in effect on the Date of Grant and the provisions of this Agreement, except as provided otherwise herein, the provisions of the Plan shall govern. All references herein to the Plan shall mean the Plan as in effect on the date hereof.

9.Bound by Plan. In consideration of the grant of the Restricted Stock Units, you agree that you will comply with such conditions as the Committee may impose on the Restricted Stock Units and be bound by the terms of the Plan.

10.Employment Status. This Agreement does not constitute a contract of employment nor does it alter your terminable at will status or otherwise guarantee future employment.

11.Binding Effect. This Agreement shall be binding upon, enforceable against, and inure to the benefit of you and your legatees, distributees and personal representatives, and Capital One and its successors and assigns.

12.Performance-Based Adjustments, Clawbacks and Other Forfeiture Events.

a.Performance-Based Adjustment. The number of Restricted Stock Units vesting on the Vesting Date shall be subject to reduction as follows:

i.For each fiscal year of the Company ending during the Performance Period, if any, that the Core Earnings for the Company for such fiscal year, as certified by the Committee, are not positive (i.e., Core Earnings are not greater than zero):

(A)    The number of Restricted Stock Units scheduled to vest on the Vesting Date shall be reduced by [# of Units];

(B)    The Committee shall determine the extent, if any, to which you are accountable for such outcome, and, based on such determination, the Committee shall determine (I) whether the number of Restricted Stock Units scheduled to vest on the Vesting Date shall be reduced by up to an additional [# of Units]and (II) whether the Vesting Date shall be delayed for all or any portion of such Restricted Stock Units that are not so reduced.

The Committee shall make the determinations referenced in Section 12(a)(i)(B) in its sole discretion, taking into account the factors set forth on Appendix A hereto.

ii.For purposes of this Section 12(a), “Core Earnings” means the Company’s net income available to common stockholders, excluding, on a tax-adjusted basis, the impact of (A) impairment or amortization of goodwill and intangible assets, and (B) the build or release of the allowance for credit losses, calculated as the difference between the provision (benefit) for credit losses and charge-offs, net of recoveries.

iii.In the event of any change to U.S. generally accepted accounting principles affecting the treatment or classification of any component of Core Earnings, such metric shall be calculated in a manner consistent with the definitions herein to the extent practicable.

Notwithstanding anything to the contrary in this Agreement and for the avoidance of doubt, in the event of a Change of Control of Capital One, there shall be no reduction pursuant to this Section 12(a) for any fiscal year ending after the date of such Change of Control.

b.Clawback. The number of Restricted Stock Units vesting on the Vesting Date shall be subject to reduction in an amount as determined by the Committee in its sole discretion in the event that prior to the Vesting Date the Committee in its sole discretion determines that (i) there has been misconduct resulting in either a violation of law or of Capital One policy or procedures, including but not limited to the Capital One Code of Conduct, that in either case causes significant financial or reputational harm to Capital One and (ii) either you committed the misconduct or failed in your responsibility to manage or monitor the applicable conduct or risks.

c.Forfeiture Event. You agree to reimburse the Company with respect to the Restricted Stock Units to the extent required under Section 304 of the Sarbanes-Oxley Act of 2002, Section 954 of the Dodd-Frank Act or as otherwise required by law.

13.Rights as a Stockholder. You shall have no rights of a stockholder with respect to the shares of Common Stock represented by Restricted Stock Units, including, but not limited to, the right to vote and to receive dividends, unless and until such shares of Common Stock are transferred to you pursuant to the Plan and this Agreement.

14.Data Protection. You consent to the collection, processing and transfer (including international transfer) of your personally identifiable data in connection with the grant of the Restricted Stock Units and participation in the Plan.

15.Severability. This Agreement shall be enforceable to the fullest extent allowed by law. In the event that any provision of this Agreement is determined to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, then that provision shall be reduced, modified or otherwise conformed to the relevant law, judgment or determination to the degree necessary to render it valid and enforceable without affecting the validity, legality or enforceability of any other provision of this Agreement or the validity, legality or enforceability of such provision in any other jurisdiction. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be deemed severable from the remainder of this Agreement, and the remaining provisions contained in this Agreement shall be construed to preserve to the maximum permissible extent the intent and purposes of this Agreement.

16.Counterparts. This Agreement may be executed in counterparts, all of which together shall constitute one agreement binding on all the parties hereto, notwithstanding that all such parties are not signatories to the original or the same counterpart

f.the Company reserves the right to impose other requirements on the Restricted Stock Units, any Shares acquired pursuant to the Restricted Stock Units, and your participation in the Plan, to the extent Capital One determines, in its sole discretion, that such other requirements are necessary or advisable in order to comply with local laws, rules and regulations, or to facilitate the administration of the Restricted Stock Units and the Plan. Such requirements may include (but are not limited to) requiring you to sign any agreements or undertakings that may be necessary to accomplish the foregoing; and
