An individual shall cease to be a Participant on the date on which the individual ceases to be an employee of the Employer other than by way of a Qualifying Termination. Except as provided in the next sentence, the Committee may, by resolution, discontinue an individual’s status as a Participant; provided, however, that no such discontinuance shall become effective (i) during the one-year period following the date on which advance written notice of such discontinuance is provided to the affected Participant in the manner specified in Section 7.08, or (ii) during the period beginning on the effective date of a Change in Control and ending 24 months after the effective date of such Change in Control. In the event that an individual incurs a Qualifying Termination while still a Participant, such individual shall remain a Participant until all compensation and benefits required to be provided to the Participant under the terms of the Plan on account of such Qualified Termination have been so provided.

Section 1.01Qualifying Termination

(a)Eligibility. Upon a Qualifying Termination, a Participant shall be entitled to receive (i) the Base Salary accrued through the date on which the Participant’s employment is terminated, (ii) any amounts owing to the Participant for reimbursement of expenses properly incurred by the Participant prior to the date on which the Participant’s employment is terminated and which are reimbursable in accordance with the Employer’s policies and procedures as in effect from time to time, and (iii) any other vested accrued benefits of the Participant under the plans, programs and arrangements of the Employer. In addition, a Participant will be eligible for the Severance Benefits described in this Section 4.01 upon a Qualifying Termination, subject to (i) the Participant executing the Participation Agreement in accordance with Section 3.01 and (ii) the Release requirement specified below. Within seven (7) days following the date of the Participant’s Separation from Service, the Company shall provide the Participant with a Release. As a condition of receiving the Severance Benefits described in subsections (b), (c), (d) and (e), the Participant must execute and deliver the Release to the Company within the Release Consideration Period, the Release Revocation Period must expire without revocation of the Release by the Participant, and the Participant must comply with the restrictive covenants set forth in the Participation Agreement. In the event the Participant breaches one or more of such restrictive covenants, the Participant will forfeit any such Severance Benefits that have not been paid or provided to the Participant and must repay to the Company the amount (or equivalent cash value) of any such Severance Benefit that has been paid to the Participant.

(b)Severance Amount. The Company shall pay to the Participant an amount equal to 0.75 times the Base Salary (the “Severance Amount”); provided, however, that if the Participant’s Qualifying Termination occurs within 24 months following the effective date of a Change in Control, then the Severance Amount shall instead be an amount equal to the following: for Tier I Participants, 1.50 times the sum of (i) the Base Salary and (ii) the Target Bonus; and for Tier II Participants, 1.00 times the sum of (i) the Base Salary and (ii) the Target Bonus. The Severance Amount shall be paid to the Participant in a lump sum within sixty (60) days following the date of the Participant’s Separation from Service (except as provided in Section 4.02(d) and subject to the requirements of Section 4.02(e)).

(c)Pro-Rata Bonus for Year of Termination.

(i)If, prior to a Change in Control the Participant’s Qualifying Termination occurs after the end of the first quarter of the calendar year in which the Separation from Service occurs, the Company shall pay to the Participant a lump sum cash amount equal to the annual cash incentive payment to which the Participant would have been entitled under the annual cash incentive plan maintained by the Employer for the performance period containing the date of the Qualifying Termination, determined on the basis of actual achievement of the performance goals applicable under such plan for such performance period, multiplied by a fraction (i) the numerator of which equals the number of days in such performance period during which the Participant was employed by the Employer (rounded up to the next highest number of days in the case of a partial day of employment), and (ii) the denominator of which is the total number of days in such performance period (the “Actual Pro-Rata Bonus”). This amount shall be paid to the Participant in a lump sum on the later of (x) the date on which the Actual Pro-Rata Bonus would have been paid to the Participant under such plan but for the Participant’s termination of employment during such

performance period, or (y) within sixty (60) days following the date of the Participant’s Separation from Service (except as provided in Section 4.02(d) and subject to the requirements of Section 4.02(e)). For the avoidance of doubt, if prior to a Change in Control the Participant’s employment terminates during the first quarter of a calendar year, the Participant shall not be entitled to receive a pro-rata bonus for the year of termination pursuant to this Section 4.01(c).

(ii)Upon the Participant’s Qualifying Termination occurring on or following a Change in Control, the Company shall pay to the Participant an amount equal to the Participant’s Target Bonus, multiplied by a fraction (i) the numerator of which equals the number of days in such performance period during which the Participant was employed by the Employer (rounded up to the next highest number of days in the case of a partial day of employment), and (ii) the denominator of which is the total number of days in such performance period (the “CIC Pro-Rata Bonus”). The CIC Pro-Rata Bonus shall be paid to the Participant in a lump sum within sixty (60) days following the date of the Participant’s Separation from Service (except as provided in Section 4.02(d) and subject to the requirements of Section 4.02(e)).

(d)Prior Year Bonus. If, on account of the Participant’s termination of employment with the Employer, the Participant forfeits the Participant’s right to earn a payment under an annual cash incentive plan maintained by the Employer for the performance period ending immediately prior to the date of such termination of employment, the Company shall pay to the Participant a lump sum cash payment equal to the amount of the annual cash incentive payment to which the Participant would have been entitled under such plan for such performance period but for the Participant’s termination of employment, determined on the basis of actual achievement of the performance goals applicable under such plan for such performance period (the “Prior Year Bonus”). This amount shall be paid to the Participant in a lump sum on the later of (x) the date on which the Prior Year Bonus would have been paid to the Participant under such plan but for the Participant’s termination of employment during such performance period, or (y) within sixty (60) days following the date of the Participant’s Separation from Service (except as provided in Section 4.02(d) and subject to the requirements of Section 4.02(e)).

(e)COBRA. (US Participants only) Upon the Participant’s Separation from Service, the Participant may elect health care coverage pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”). Subject to Section 4.02(d) and the requirements of Section 4.02(e), the Employer will pay for up to nine months (the “Continuation Period”), on an after-tax basis, the portion of the Participant’s COBRA premiums for such coverage that exceeds the amount that the Participant would have incurred in premiums for such coverage under the Employer’s health plan if then employed by the Employer; provided, however, that if the Participant’s Qualifying Termination occurs within 24 months following the effective date of a Change in Control, then the Continuation Period shall instead be up to 18 months for Tier I Participants and up to 12 months for Tier II Participants; provided, further, that the Employer’s obligation shall only apply to the extent COBRA coverage is elected and in effect during the Continuation Period. Following the end of the Continuation Period, the Participant will be responsible for the full amount of all future premium payments should he or she wish to continue COBRA coverage. However, if the Participant becomes eligible for group health coverage sponsored by another employer (regardless of whether such coverage is actually elected) or for any other reason the Participant’s COBRA coverage terminates, the Employer shall not be obligated to pay any portion of the premiums provided hereunder for periods after the Participant becomes eligible for such other coverage or the Participant’s COBRA coverage

terminates. The Participant shall have the obligation to notify the Employer if he or she becomes eligible for group health coverage sponsored by another employer.

(f)Equity Awards. The Participant’s outstanding equity and equity-based awards shall be treated in the manner set forth in the Omnibus Incentive Plan and the applicable award agreements issued thereunder.

Section 1.02Sections 409A and 457A

(a)Severance Benefits under the Plan are intended to comply with the applicable requirements of Section 409A of the Code (“Section 409A”) and Section 457A of the Code (“Section 457A”), or the requirements for exemption from Section 409A or Section 457A, as applicable, and shall be construed and administered accordingly. In no event shall the Company, the Subsidiaries, or their respective directors, officers, employees and advisers be liable for any tax, penalty, or other loss in connection with any failure or alleged failure to comply with Section 409A or Section 457A, or an exemption therefrom. Sections 4.02(b), (c), (d) and (e) will apply to the extent Severance Benefits are non-exempt deferred compensation subject to the requirements of Section 409A (“Deferred Compensation”), as determined by the Company, notwithstanding anything in the Plan to the contrary.

(b)All references in the Plan to “termination of employment” or similar or correlative phrases shall be construed to require a Separation from Service from the Employer and from all other corporations and trades or businesses, if any, that would be treated as a “service recipient” with the Employer under Section 409A. Any written election by the Company for purposes of determining whether a “separation from service” has occurred under Section 409A (subject to any applicable limitations therein) shall be deemed part of this Plan.

(c)Any right to Deferred Compensation that would be paid in a series of installment payments is to be treated as a right to a series of separate payments.

(d)If a Participant is a “specified employee” at the relevant time (as determined by the Company in accordance with Section 409A) (the “Severance Event”), Deferred Compensation that would (but for this sentence) be payable within six months following such Severance Event shall instead be accumulated and paid, without interest, on the date that follows the date of such Severance Event by six (6) months and one day (or, if earlier, the date of the Participant’s death). A “specified employee” means an individual who is determined by the Company to be a specified employee within the meaning of Section 409A. Any written election by the Company for purposes of determining “specified employee” status under Section 409A (subject any applicable limitations therein) shall be deemed part of the Plan.

(e)If the timing of the payment or commencement of Deferred Compensation is contingent upon the expiration of all applicable rights of revocation with respect to any Release and if the designated period within which such Release can be revoked begins in one calendar year and ends in the next calendar year, such Deferred Compensation shall be paid or commence, if at all, in the next calendar year.

(f)To the extent required in order to avoid an accelerated or additional tax under Section 409A, amounts reimbursable to the Participant under this Plan shall be paid to the Participant on or before the last day of the year following the year in which the expense was incurred and the amount of expenses eligible for reimbursement (and in-kind benefits provided to the Participant) during one year may not affect amounts reimbursable or provided in any subsequent year.

(g)With respect to any equity and equity-based awards held by the Participant that constitute Deferred Compensation, to the extent the payment of such awards is accelerated in connection with this Plan, the payment of such awards shall instead be made at the earliest time permitted that will not trigger a tax or penalty under Section 409A.

Section 1.03Section 280G

(a)A Participant shall bear all expense of, and be solely responsible for, any Excise Tax; provided, however, that any payment or benefit received or to be received by the Participant (whether payable under the terms of this Plan or any other plan, arrangement or agreement with the Employer or any of its Affiliates) (collectively, the “Payments”) that would constitute a “parachute payment” within the meaning of Code Section 280G shall be reduced to the extent necessary so that no portion thereof shall be subject to the Excise Tax but only if, by reason of such reduction, the net after-tax benefit received by the Participant shall exceed the net after-tax benefit that would be received by the Participant if no such reduction was made.

(b)The “net after-tax benefit” shall mean (i) the Payments which the Participant receives or is then entitled to receive from the Employer that would constitute “parachute payments” within the meaning of Code Section 280G, less (ii) the amount of all federal, state and local income and employment taxes payable by the Participant with respect to the foregoing calculated at the highest marginal income tax rate for each year in which the foregoing shall be paid to the Participant (based on the rate in effect for such year as set forth in the Code as in effect at the time of the first payment of the foregoing), less (iii) the amount of Excise Tax imposed with respect to the payments and benefits described in (b)(i) above.

(c)All determinations under this Section 4.03 will be made by an Accounting Firm. The Accounting Firm shall be required, in part, to evaluate the extent to which payments are exempt from Section 280G as reasonable compensation for services rendered before or after the Change in Control. All fees and expenses of the Accounting Firm shall be paid solely by the Company. The Company will direct the Accounting Firm to submit any determination it makes under this Section 4.03 and detailed supporting calculations to both the Participant and the Company as soon as reasonably practicable following the Change in Control.

(d)If, the Accounting Firm determines that one or more reductions are required under this Section 4.03, such Payments shall be reduced in the order that would provide the Participant with the largest amount of after-tax proceeds (with such order, to the extent permitted by Code Sections 280G and 409A designated by the Participant, or otherwise determined by the Accounting Firm) to the extent necessary so that no portion thereof shall be subject to the Excise Tax, and the Company shall pay such reduced amount to the Participant. The Participant shall at any time have the unilateral right to forfeit any equity award in whole or in part.

(e)As a result of the uncertainty in the application of Code Section 280G at the time that the Accounting Firm makes its determinations under this Section 4.03, it is possible that amounts will have been paid or distributed to the Participant that should not have been paid or distributed (collectively, the “Overpayments”), or that additional amounts should be paid or distributed to the Participant (collectively, the “Underpayments”). If the Accounting Firm determines, based on either the assertion of a deficiency by the Internal Revenue Service against the Employer or the Participant, which assertion the Accounting Firm believes has a high probability of success or is otherwise based on controlling precedent or substantial authority, that an Overpayment has been made, the Participant must repay the Overpayment to the Company, without interest; provided, however, that no loan will be deemed to have been made and no amount will be payable by the Participant to the Company unless, and then only to the extent that, the deemed loan and payment would either reduce the amount on which the Participant is subject to tax under Code Section 4999 or generate a refund of tax imposed under Code Section

4999. If the Accounting Firm determines, based upon controlling precedent or substantial authority, that an Underpayment has occurred, the Accounting Firm will notify the Participant and the Company of that determination, and the Company will promptly pay the amount of that Underpayment to the Participant without interest.

(f)The parties will provide the Accounting Firm access to and copies of any books, records, and documents in their possession as reasonably requested by the Accounting Firm, and otherwise cooperate with the Accounting Firm in connection with the preparation and issuance of the determinations and calculations contemplated by this Section 4.03. For purposes of making the calculations required by this Section 4.03, the Accounting Firm may rely on reasonable, good faith interpretations concerning the application of Code Sections 280G and 4999.

Section 1.04ERISA

(a)The Plan is established pursuant to, and governed by, ERISA. The Plan is intended to constitute a “severance pay arrangement” within the meaning of Section 3(2)(B)(i) of ERISA so as to be excepted from the definitions of “employee pension benefit plan” and “pension plan” set forth under section 3(2) of ERISA, and is intended to meet the descriptive requirements of a plan constituting a “severance pay plan” within the meaning of regulations published by the Secretary of Labor at Title 29, Code of Federal Regulations § 2510.3−2(b). In the event that the Plan does not meet the requirements a “severance pay arrangement” or “severance pay plan” as described above, the Plan is intended is intended to be “a plan which is unfunded and maintained by an employer primarily for the purpose of providing deferred compensation for a select group of management or highly compensation employees”, within the meaning of Sections 201(2), 301(a)(3) and 401(a)(1) of ERISA. The Plan shall be interpreted consistent with the foregoing.

(b)The benefits provided herein shall be funded by the Company’s general assets. The Plan shall constitute an unfunded mechanism for the Company to pay Plan benefits to the Participants determined to be eligible for payments hereunder. No fund or trust is created with respect to the Plan, and no Person shall have any security or other interest in the assets of the Company.

(c)The Company is the plan sponsor and “named fiduciary” of the Plan within the meaning of Section 402(a) of ERISA.

(d)This document is intended to serve as both the Plan’s legal plan document and summary plan description for all purposes under ERISA.

Subject to the next sentence, the Committee shall have the right at any time and from time to time, by instrument in writing, to amend, modify, alter, or terminate the Plan in whole or in part. Notwithstanding the foregoing or anything in this Plan to the contrary, the Committee may not amend, modify, alter or terminate this Plan so as to adversely affect payments or benefits then payable, or which could become payable, to a Participant under the Plan, except to the minimum extent required to comply with any applicable law, (i) during the one-year period following the date on which advance written notice of such amendment, modification, alteration or termination is provided to the affected Participant in the manner specified in Section 7.08, or (ii) during the period beginning on the effective date of a Change in Control and ending 24 months after the effective date of such Change in Control.

In no event shall such extension exceed a period of ninety (90) days from the end of such initial period. The extension notice shall indicate the special circumstances requiring an extension of time and the date by which the Plan expects to render the benefit determination. The period of time within which a benefit determination is required to be made shall begin at the time a claim is filed in accordance with the reasonable procedures established by the Committee, without regard to whether all the information necessary to make a benefit determination accompanies the filing.

The notification shall set forth, in a manner calculated to be understood by the claimant: (i) the specific reason or reasons for the adverse determination; (ii) reference to the specific Plan provisions on which the determination is based; (iii) a description of any additional material or information necessary for the claimant to perfect the claim and an explanation of why such material or information is necessary; and (iv) a description of the Plan’s review procedures and the time limits applicable to such procedures, including a statement of the claimant’s right to bring a civil action under section 502(a) of ERISA following an adverse benefit determination on review. Such notification shall provide the claimant the opportunity to submit written comments, documents, records, and other information relating to the claim for benefits. The claimant shall be provided, upon request and free of charge, reasonable access to, and copies of, all documents, records, and other information relevant to the claimant’s claim for benefits. A document, record, or other information shall be considered “relevant” to a claimant’s claim if such document, record, or other information: (i) was relied upon in making the benefit determination; (ii) was submitted, considered, or generated in the course of making the benefit determination, without regard to whether such document, record, or other information was relied upon in making the benefit determination; or (iii) demonstrates compliance with the administrative processes and safeguards established by the Committee to ensure and to verify that benefit claim determinations are made in accordance with governing plan documents and that, where appropriate, the Plan provisions have been applied consistently with respect to similarly situated claimants.

Section 1.04Review of Denial

Within sixty (60) days of the receipt by the claimant of written or permitted electronic notification of an adverse benefit determination, the claimant may file a written request with the

Committee that it conduct a full and fair review of the denial of the claimant’s claim for benefits. A review by the Committee shall take into account all comments, documents, records, and other information submitted by the claimant relating to the claim, without regard to whether such information was submitted or considered in the initial benefit determination. The period of time within which a benefit determination on review is required to be made shall begin at the time an appeal is filed in accordance with the reasonable procedures established by the Committee, without regard to whether all the information necessary to make a benefit determination on review accompanies the filing. In the event that a period of time is extended due to a claimant’s failure to submit information necessary to decide a claim, the period for making the benefit determination on review shall be tolled from the date on which the notification of the extension is sent to the claimant until the date on which the claimant responds to the request for additional information.

Section 1.05Decision on Review

The Committee shall notify a claimant, in accordance with Section 7.06 of the Plan, of its benefit determination on review of a claimant’s appeal of an adverse benefit determination within a reasonable period of time, but not later than sixty (60) days after receipt of the claimant’s request for review by the Committee, unless the Committee determines that special circumstances (such as the need to hold a hearing, if the Plan’s procedures provide for a hearing) require an extension of time for processing the claim. If the Committee determines that an extension of time for processing is required, written notice of the extension shall be furnished to the claimant prior to the termination of the initial sixty-day period. In no event shall such extension exceed a period of sixty (60) days from the end of the initial period. The extension notice shall indicate the special circumstances requiring an extension of time and the date by which the Committee expects to render the determination on review.

Section 1.06Notice of Decision on Review

The Committee shall notify the claimant of the benefit determination as soon as possible, but not later than five (5) days after the benefit determination is made with written or electronic notification of the Committee’s benefit determination of the claimant’s appeal of the benefit denial. Any electronic notification shall comply with the standards imposed by 29 CFR 2520.104b-1(c)(I)(i), (iii), and (iv). In the case of an adverse benefit determination, the notification shall set forth, in a manner calculated to be understood by the claimant: (i) the specific reason or reasons for the adverse determination; (ii) reference to the specific plan provisions on which the benefit determination is based; (iii) a statement that the claimant is entitled to receive, upon request and free of charge, reasonable access to, and copies of, all documents, records, and other information relevant to the claimant’s claim for benefits; and (iv) a statement of the claimant’s right to bring an action under section 502(a) of ERISA.

Section 1.01Clawback

Notwithstanding any provision in the Plan to the contrary, any portion of the payments and benefits provided under the Plan, as well as any other payments and benefits which a Participant receives pursuant to an Argo Group plan or other arrangement, shall be subject to a clawback (a) to the extent necessary to comply with the requirements of the Dodd-Frank Wall Street Reform and Consumer Protection Act or any Securities and Exchange Commission rule or (b) as provided for under any clawback policy adopted by the Company from time to time.

Section 1.02Participant Rights

Except to the extent required or provided for by mandatorily imposed law as in effect and applicable hereto from time to time, neither the establishment of the Plan, nor any modification thereof, nor the creation of any fund or account, nor the payment of any benefits, shall be construed as giving to any Participant or other person any legal or equitable right against the Employer, or any officer or employee thereof, or the Board or the Committee, except as herein provided; nor shall any Participant have any legal right, title or interest in the assets of the Employer, except in the event and to the extent that benefits may actually be payable to him or her hereunder. This Plan shall not constitute a contract of employment nor afford any individual any right to be retained or continued in the employ of the Employer or in any way limit the right of the Employer to discharge any of its employees, with or without cause. Participants have no right to receive any payments or benefits that the Employer is prohibited by applicable law from making.

Section 1.03Plan Administration; Committee Authority

(a)The general administration of the Plan shall be vested in the Committee. For purposes of ERISA, the Committee shall be the “Plan Administrator” and shall be a “fiduciary” with respect to the administration of the Plan.

(b)The members of the Committee shall not receive compensation with respect to their services for the Committee in respect of this Plan. To the extent required by ERISA or other applicable law, or required by the Company, members of the Committee shall furnish bond or security for the performance of their duties hereunder. Any expenses properly incurred by the Committee incident to the administration, termination or protection of the Plan, including the cost of furnishing any bond or security, shall be paid by the Company.

(c)The Committee will administer the Plan and have the full authority and discretion necessary to accomplish that purpose, including, without limitation, the authority and discretion to:

(i)resolve all questions relating to the eligibility of Participants;

(ii)determine the amount of benefits, if any, payable to Participants under the Plan and determine the time and manner in which such benefits are to be paid;

(iii)engage any administrative, legal, tax, actuarial, accounting, clerical, or other services it deems appropriate in administering the Plan;

(iv)construe and interpret the Plan, supply omissions from, correct deficiencies in and resolve inconsistencies or ambiguities in the language of the Plan, resolve inconsistencies or ambiguities between the provisions of this document, and adopt rules for the administration of the Plan which are not inconsistent with the terms of the Plan document;

(v)modify or supplement the terms of the Plan to the extent necessary to ensure that the Plan complies with local law;

(vi)compile and maintain all records it determines to be necessary, appropriate or convenient in connection with the administration of the Plan;

(viii)resolve all questions of fact relating to any matter for which it has administrative responsibility.

(d)The Committee shall perform all of the duties and may exercise all of the powers and discretion that the Committee deems necessary or appropriate for the proper administration of the Plan, including, but not limited to, delegation of any of its duties to one or more authorized officers. All references to the authority of the Committee in this Plan shall be read to include the authority of any party to which the Committee delegates such authority.

(e)Any failure by the Committee to apply any provisions of this Plan to any particular situation shall not represent a waiver of the Committee’s authority to apply such provisions thereafter. Every interpretation, choice, determination or other exercise of any power or discretion given either expressly or by implication to the Committee shall be final, conclusive and binding upon all parties having or claiming to have an interest under the Plan or otherwise directly or indirectly affected by such action, without restriction, however, on the right of the Committee to reconsider and re-determine such action.

(f)Any decision, determination, or other action rendered or made by the Committee shall be final and binding upon the parties, and any review of such decision, determination or other action shall be limited to determining whether the decision, determination or action was so arbitrary and capricious as to be an abuse of discretion. It is intended that a court will give deference to any discretionary determination of the Committee when adjudicating any action or claim brought under Section 502 of ERISA that challenges such Committee determination.

(g)The Committee may adopt such rules and procedures for the administration of the Plan as are consistent with the terms hereof.

Section 1.04Expenses

All Plan administration expenses shall be paid by the Company.

Section 1.05Successors

(a)This Plan shall bind any successor of or to the Company, its assets or its businesses (whether direct or indirect, by purchase, merger, consolidation or otherwise), in the same manner and to the same extent that the Company would be obligated under this Plan if no succession had taken place. In the case of any transaction in which a successor would not by the foregoing provision or by operation of law be bound by this Plan, the Company shall require such successor expressly and unconditionally to assume and agree to perform the Company’s obligations under this Plan, in the same manner and to the same extent that the Company would be required to perform if no such succession had taken place.

(b)The Plan shall inure to the benefit of and be binding upon and enforceable by the Company and the Participants and their personal and legal representatives, executors, administrators, successors, assigns, heirs, distributees, devisees and legatees.

Section 1.10Withholding of Taxes

The Employer may withhold from any amount payable or benefit provided under this Plan such Federal, state, local, foreign and other taxes as are required to be withheld pursuant to any applicable law or regulation.

Section 1.11Choice of Law; Jurisdiction

All questions or disputes concerning this Plan shall be governed by and construed in accordance with ERISA or, to the extent not preempted by ERISA, in accordance with the internal laws of the State of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of New York or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of New York. To the extent applicable, the Participants hereby: (i) submit to the non-exclusive jurisdiction of any federal court sitting in the State of New York in any action or proceeding arising out of or relating to this Plan; and (ii) agree that all claims in respect of such action or proceeding may be heard or determined in any such court. The Employer and the Participants hereby waive any defense of inconvenient forum to the maintenance of any action or proceeding so brought. The Employer and the Participants hereby agree that a final judgment in any action or proceeding so brought shall be conclusive and may be enforced by suit on the judgment or in any other manner provided by law.

Section 1.12Waiver of Jury Trial; Legal Fees

(a)The Employer and the Participants agree that any action, demand, claim or counterclaim relating to the terms and provisions of this Plan, or to its breach, may be commenced in federal court in the State of New York. The Employer and the Participants further agree that any action, demand, claim or counterclaim shall be resolved by a judge alone, and the Employer and the Participants hereby waive and forever renounce that right to a trial before a civil jury.

(b)Without limiting the generality of the foregoing, on or following a Change in Control, the Company shall pay to the Participant all legal fees and expenses incurred by the Participant in disputing in good faith any issue under the Plan relating to the termination of the Participant’s employment, in seeking in good faith to obtain or enforce any benefit or right provided by this Plan or in connection with any tax audit or proceeding to the extent attributable to the application of Section 4999 of the Code to any payment or benefit provided under the Plan. Such payments shall be made within five (5) business days after delivery of the Executive's written requests for payment accompanied with such evidence of fees and expenses incurred as the Company reasonably may require.

Section 1.13Validity/Severability

If any provision of this Plan or the application of any provision to any person or circumstances is held invalid, unenforceable or otherwise illegal, the remainder of this Plan and the application of such provision to any other person or circumstances will not be affected, and the provision so held to be invalid or unenforceable will be reformed to the extent (and only to the extent) necessary to make it enforceable or valid. To the extent any provisions held to be invalid or unenforceable cannot be reformed, such provisions are to be stricken here from and the remainder of this Plan will be binding on the Parties and their successors and assigns as if such invalid or illegal provisions were never included in this Plan from the first instance.

Section 1.14Miscellaneous

No waiver by a Participant or the Employer at any time of any breach by the other party of, or compliance with, any condition or provision of this Plan to be performed by such other party shall be deemed a waiver of similar or dissimilar provisions or conditions at the time or at any prior or subsequent time. No agreements or representations, oral or otherwise, express or implied, with respect to the subject matter hereof have been made by either party that are not expressly set forth in this Plan.

Section 1.15Source of Payments

All payments provided under this Plan, other than payments made pursuant to any Employer employee benefit plan which provides otherwise, shall be paid in cash from the general funds of the Company, and no special or separate fund shall be required to be established, and no other segregation of assets required to be made, to assure payment. To the extent that any person acquires a right to receive payments from the Company under this Plan, such right shall be no greater than the right of an unsecured creditor of the Company.

Section 1.16Survival of Provisions

Notwithstanding any other provision of this Plan, the rights and obligations of the Company and the Participants under Article Four and Sections 7.06 through 7.16 will survive any termination or expiration of this Plan or the termination of the Participant’s employment for any reason whatsoever.

Section 1.17ERISA Rights Statement

Plan Participants are entitled to certain rights and protections under ERISA. ERISA provides that all Plan Participants will be entitled to:

(a)Receive Information About Your Plan and Benefits

Examine, without charge, at the Plan Administrator’s office and at other specified locations, all Plan documents, including the Plan and a copy of the latest annual report (Form 5500 Series) filed by the Plan with the U.S. Department of Labor and available at the Public Disclosure Room of the Employee Benefits Security Administration.

Obtain, upon written request to the Plan Administrator, copies of Plan documents, including the Plan and copies of the latest annual report (Form 5500 Series). The Plan Administrator may require a reasonable charge for the copies.

(b)Prudent Actions by Plan Fiduciaries

In addition to creating rights for Plan Participants ERISA imposes duties upon the people who are responsible for the operation of the employee benefit plan. The people who operate your Plan, called “fiduciaries” of the Plan, have a duty to do so prudently and in the interest of you and other Plan participants and beneficiaries. No one, including your employer or any other person, may fire you or otherwise discriminate against you in any way to prevent you from obtaining a welfare benefit or exercising your rights under ERISA.

(c)Enforce Your Rights

If your claim for a welfare benefit is denied or ignored, in whole or in part, you have a right to know why this was done, to obtain copies of documents relating to the decision without charge, and to appeal any denial, all within certain time schedules.

Under ERISA, there are steps you can take to enforce the above rights. For instance, if you request a copy of the Plan documents or the latest annual report from the Plan and do not receive them within 30 days, you may file suit in a federal court. In such a case, the court may require the Plan Administrator to provide the materials and pay you up to $110 a day until you receive the materials, unless the materials were not sent because of reasons beyond the control of the Plan Administrator. If you have a claim for benefits which is denied or ignored, in whole or in part, you may file suit in a state or Federal court. In addition, if you disagree with the Plan’s decision or lack thereof concerning the qualified status of a domestic relations order or a medical child support order, you may file suit in a Federal court.

If it should happen that the Plan fiduciaries misuse the Plan’s money or if you are discriminated against for asserting your rights, you may seek assistance from the U.S. Department of Labor, or you may file suit in a Federal court. The court will decide who should pay court costs and legal fees. If you are successful the court may order the person you have sued to pay these costs and fees. If you lose, the court may order you to pay these costs and fees, for example, if it finds your claim is frivolous. However, no legal action may be commenced or maintained against the Plan prior until after you exhaust the Plan's claims procedures, which are described in Article Seven.

(d)Assistance with Your Questions

If you have any questions about your Plan, you should contact the Plan Administrator. If you have any questions about this statement or about your rights under ERISA, or if you need assistance in obtaining documents from the Plan Administrator, you should contact the nearest office of the Employee Benefits Security Administration, U.S. Department of Labor, listed in your telephone directory or the Division of Technical Assistance and Inquiries, Employee Benefits Security Administration, U.S. Department of Labor, 200 Constitution Avenue N.W., Washington, D.C. 20210. You may also obtain certain publications about your rights and responsibilities under ERISA by calling the publications hotline of the Employee Benefits Security Administration.

Notwithstanding anything to the contrary contain herein, the Company and the Participant acknowledge that pursuant to 18 USC § 1833(b), the Participant may not be held liable under any U.S. criminal or civil Federal or State trade secret law for disclosure of a trade secret of the Company: that (i) is made (A) in confidence to a Federal, State, or local government official, either directly or indirectly, or to the Participant’s attorney and (B) solely for the purpose of reporting or investigating a suspected violation of law; or (ii) is made in a complaint or other document that is filed under seal in a lawsuit or other proceeding.

Nothing in this Agreement is intended to conflict with 18 U.S.C. § 1833(b) or create liability for disclosures of trade secrets that are expressly allowed by such section. Notwithstanding anything to the contrary contained in this Agreement, this Agreement does not (x) prohibit the Participant from providing truthful testimony or accurate information in connection with any investigation being conducted into the business or operations of the Company, or any related targets, by any government agency or other regulator that is responsible for enforcing a law on behalf of the government, or otherwise providing information to a government regulatory agency or body regarding conduct or action undertaken or omitted to be taken by the Company that the Participant reasonably believes is illegal or in material non-compliance with any financial disclosure or other regulatory requirement applicable to the Company, or in connection with any dispute between the Participant and the Company Group; (y) require the Participant to obtain the approval of, or give notice to, the Company or any of its representatives to take any action permitted under the preceding clause (x); or (z) apply to information that (i) was at the time of receipt within the public knowledge without any breach by the Participant, (ii) subsequently is lawfully acquired from a third party without continuing restriction on use, without any breach by the Employee or (iii) was disclosed in a communication subject to attorney-client privilege.

The Participant recognizes that, while performing duties for the Company, the Participant will have access to and come into contact with trade secrets and Confidential Information belonging to the Company Group and the Participant will obtain personal knowledge of and influence over its customers and/or employees. The Participant therefore agrees that the restrictions set out in this Section 6 are reasonable and necessary to protect the legitimate business interests of the Company Group both during and after the termination of the Participant’s employment.

The Participant hereby undertakes with the Company that the Participant will not during the Participant’s employment with the Company and for the period of nine (9) months after the Participant ceases to be employed by the Company for any reason whatsoever (or [eighteen (18) / twelve (12)]7 months if the Participant’s cessation of employment occurs within twenty-four (24) months following a Change in Control), whether by the Participant’s self, through the Participant’s employers or employees or agents, or otherwise howsoever and whether on the Participant’s own behalf or on behalf of any other person, firm, company or other organization directly or indirectly:

The Participant hereby undertakes with the Company that the Participant shall not during the Participant’s employment with the Company and for the period of nine (9) months after the Participant ceases to be employed by the Company for any reason whatsoever (or [eighteen (18) / twelve (12)]8 months if the Participant’s cessation of employment occurs within twenty-four (24) months following a Change in Control), without the prior written consent of the Company, whether by the Participant’s self, through the Participant’s employers or employees or agents or otherwise, howsoever and whether on the Participant’s own behalf or on behalf of any other person, firm, company or other organization directly or indirectly:

8     Note to Draft: Tier I Participant is at 18 months / Tier II Participant is at 12 months.

(ii)solicit or induce or endeavor to solicit or induce any Restricted Employee to cease working for or providing services to the Company, or hire any Restricted Employee.

The Participant agrees that during the nine (9) months after the Participant ceases to be employed by the Company for any reason whatsoever (or [eighteen (18) / twelve (12)]9 months if the Participant’s cessation of employment occurs within twenty-four (24) months following a Change in Control), the Participant shall inform the Company, prior to the commencement of employment or any work as an independent contractor, of the identity of any new employer or other entity to which the Participant plans to provide consulting or other services, along with the Participant’s starting date, title, job description and any other information which the Company may reasonably request (and which does not violate any confidentiality obligation of the Participant) to confirm the Participant’s compliance with the terms of this Agreement.

Subject to Section 5, participant shall not, at any time during the Participant’s employment with the Company and thereafter, make statements or representations, or otherwise communicate, directly or indirectly, in writing, orally, or otherwise, or take any action which is reasonably likely to be, directly or indirectly, disparaging or damaging to the Company, or its subsidiaries, or their respective officers, directors, employees, advisors, businesses or reputations. Notwithstanding the foregoing, nothing in this Agreement shall preclude the Participant from making truthful statements that are required by applicable law, regulation or legal process, including truthful statements in connection with an action, suit or other proceeding to enforce the Participant’s rights under this Agreement.

The Participant agrees that after the termination of the Participant’s employment with the Company for any reason, the Participant shall be available, upon reasonable notice and under reasonable conditions, to respond to inquiries and requests for information and assist the Company in any capacity with respect to matters of which the Participant was involved or had knowledge as a result of the Participant’s employment with the Company, including, but not limited to, providing information in connection with the Company’s operations. The Participant further agrees to provide reasonable assistance to the Company and its respective representatives in defense of any claims that have been or may be made against the Company, and will assist the Company in the prosecution of any claims that have been or may be made by the Company, to the extent that such claims may relate to the period of the Participant’s employment with the Company. The Participant’s assistance shall include but not be limited to cooperating and meeting with, and providing information to, counsel of the Company and providing honest and truthful testimony. The Participant and the Company agree that upon presentation of appropriate documentation, the Company shall pay or reimburse the Participant for all reasonable out-of- pocket travel, duplicating or telephonic expenses incurred by me in complying with this paragraph. The Participant and the Company further agree that to the extent that the Participant is required to spend substantial time on such matters, the Company shall compensate the Participant at an hourly rate based on the Participant’s base salary (or

actual hourly rate, as the case may be) in effect on the last day of the Participant’s employment with the Company.

The Participant understands that the restrictions contained in this Agreement are necessary for the protection of the business and goodwill of the Company Group and considers them to be reasonable for such purpose. Any breach of this Agreement is likely to cause the Company Group substantial and irrevocable damage and therefore, in the event of such breach, the Company Group, in addition to such other remedies which may be available, including under the terms of the Severance Plan, will be entitled to specific performance and other injunctive relief, without the posting of a bond.

The Participant is hereby advised to consult with counsel regarding the provisions of this Agreement. The Participant shall have until 5:00 pm ET on [●]10 to execute this Agreement (the “Deadline”). Failure by the Participant to execute and return this Agreement by the Deadline means that the Participant shall remain subject to the terms and conditions of the Argo Group International Holdings, Ltd. Executive Severance Plan, effective as of January 1, 2021 (the “2021 Plan”) and shall not be a participant in, and shall not be eligible for any of the payments and benefits provided under, the Severance Plan.

This Agreement shall be for the benefit of the Company Group and the Company reserves the right to assign the benefit of such provisions to any entity within the Company Group. The obligations undertaken by the Participant pursuant to this Agreement, with respect to each entity within the Company Group, constitute separate and distinct obligations and covenants and the invalidity or unenforceability of any such obligation or covenant shall not affect the validity or enforceability of the obligations or covenants in favor of any other entity within the Company Group. The Company will also have the right to assign this Agreement to its successors and assigns.

While the restrictions in this Agreement are considered by the Company and the Participant to be reasonable in all the circumstances, it is agreed that if any such restrictions, by themselves, or taken together, shall be adjudged to go beyond what is reasonable in all the circumstances for the protection of the legitimate interests of the Company Group but would be adjudged reasonable if part or parts of the wording thereof were deleted, the relevant restriction or restrictions shall apply with such deletion(s) as may be necessary to make it or them valid and effective.

The Participant and the Company agree that facsimile, scanned, PDF or email copies of this Agreement shall be considered as a legal original and signatures thereon shall be legal and binding, and that this Agreement may be executed in one or more counterparts, each of which shall be deemed an original but all of which shall constitute one and the same instrument.
