As of each date on which the Company pays a cash dividend to record owners of Common Shares (a “Dividend Date”), the number of Common Shares subject to the Award shall increase by (i) the product of the total number of shares subject to the Award immediately prior to such Dividend Date multiplied by the dollar amount of the cash dividend paid per Common Share by the Company on such Dividend Date, divided by (ii) the Fair Market Value of a Common Share on such Dividend Date.

For purposes of this Award, “Cause” shall have the meaning set forth in any then applicable employment or other similar written agreement (including such similar term or concept, as determined by the Committee) between the Holder and the Company or an Affiliate. If there is no such written agreement or if such agreement does not define Cause, then Cause shall mean (i) a material and continued failure of the Holder to perform the Holder’s duties, other than due to death or Disability, which failure has continued for more than 30 days following written notice of such nonperformance from the Company; (ii) conviction of or pleading guilty or no contest to an act of fraud, embezzlement, or misappropriation of assets or property (tangible or intangible) of the Company or any Affiliate thereof; (iii) a material breach of the Restrictive Covenant Agreement; (iv) commission of a felony, including a plea of guilty or nolo contendere, or an indictment or written admission thereof; (v) gross negligence or willful misconduct in the performance by the Holder of his duties that is reasonably likely to have an

adverse effect on the business or reputation of the Company or its Affiliates; or (vi) the Holder’s material violation of the material written policies of the Company (e.g., sexual harassment, data protection policy, etc.). For the avoidance of doubt, the definition of Cause as well as the consequences of termination for Cause as set out in the Plan, the Agreement and the Award Notice shall apply regardless of whether such termination of employment may be justified under any applicable employment protection legislation, and regardless of whether such termination may be challenged by the Holder, and regardless of whether such termination is invalidated by verdict or a court order.

(b)                                 Disability. For purposes of this Award, “Disability” shall mean, with respect to any U.S. Holder, such Holder becoming disabled under one of the Company’s long-term disability plans or becoming eligible for benefits from the Social Security Administration. For all non-U.S. Holders, Disability shall mean the Holder is incapacitated for a period of at least 180 days by accident, sickness or other circumstance that renders such Holder mentally or physically incapable of performing the material duties and services required of the Holder in the Holder’s position with the Company on a full-time basis during such period.

If there is no such written agreement or if such agreement does not define “Good Reason,” then “Good Reason” shall mean the Holder has complied with the Good Reason Process (as defined below) following the occurrence of any of the following conditions (without the Holder’s written consent or waiver): (i) a material diminution in the Holder’s responsibilities, authority or duties, unless such diminution is in connection with a Cause event; (ii) a diminution in the Holder’s annual base salary or target annual bonus opportunity; (iii) during the 24-month period following a Change in Control, a material diminution in the regular target annual long term incentive opportunity or the annual target long-term incentive award subsequently granted to the Holder in an amount less than the regular target opportunity, but in all cases disregarding the equity awards granted in connection with the Company’s going-public transaction in 2018 and other special cash or equity awards; (iv) a material change in the geographic location at which the Holder provides services to the Company; or (v) a material breach of any employment or other material agreement between the Company or one of its Affiliates and the Holder. For purposes of this Award, “Good Reason Process” shall mean that (i) the Holder reasonably determines in good faith that a Good Reason condition has occurred; (ii) the Holder notifies the Company in writing of the occurrence of the Good Reason condition within 60 days of the Holder having actual or constructive knowledge of the occurrence of such condition; (iii) the Holder cooperates in good faith with the Company’s efforts, for a period not less than 30 days following such notice (the “Cure Period”), to remedy the condition; (iv) notwithstanding such efforts, the Good Reason condition continues to exist; and (v) the Holder terminates Holder’s Employment at least 10 days, but no more than 60 days,

after the end of the Cure Period. For the avoidance of doubt, if the Company cures the Good Reason condition during the Cure Period, Good Reason shall be deemed not to have occurred.

The Holder agrees that by accepting the Award the Holder authorizes the Company and its Affiliates to deduct any amount or amounts owed by the Holder pursuant to this Section 5 from any amounts payable by or on behalf of the Company or any affiliate to the Holder, including, without limitation, any amount payable to the Holder as salary, wages, vacation pay, bonus or the vesting or settlement of the Award or any share-based award. This right of setoff shall not be an exclusive remedy and the Company’s or an Affiliate’s election not to exercise this right of setoff with respect to any amount payable to the Holder shall not constitute a waiver of this right of setoff with respect to any other amount payable to the Holder or any other remedy.

6.                                      Transfer Restrictions and Investment Representation.

6.1.                            Nontransferability of Award. The Award shall not be transferable other than by will, the laws of descent and distribution or pursuant to beneficiary designation procedures approved by the Company. Except to the extent permitted by the foregoing sentence, the Award may be exercised or settled during the Holder’s lifetime only by the Holder or the Holder’s legal representative or similar person. Except as permitted by the second preceding sentence, the Award may not be sold, transferred, assigned, pledged, hypothecated, encumbered or otherwise disposed of (whether by operation of law or otherwise) or be subject to execution, attachment or similar process. Upon any attempt to so sell, transfer, assign, pledge, hypothecate, encumber or otherwise dispose of the Award, such Award and all rights hereunder shall immediately become null and void. All transfer restrictions provided for in this Section 6.1, shall lapse when the Common Shares are issued or delivered to the Holder.

6.2.                            Investment Representation. The Holder hereby covenants that (a) any sale of any Common Share acquired upon the vesting of the Award shall be made either pursuant to an effective registration statement under the Securities Act of 1933, as amended (the “Securities Act”) and any applicable state securities laws, or pursuant to an exemption from registration under the Securities Act and such state securities laws and (b) the Holder shall comply with all regulations and requirements of any regulatory authority having control of or supervision over the issuance of the shares and, in connection therewith, shall execute any documents which the Committee shall in its sole discretion deem necessary or advisable.

7.                                      Additional Terms and Conditions of Award.

7.1.                            Survival of Other Severance Benefits and Non-Duplication.  If the Holder has executed the Restrictive Covenant Agreement prior to the date hereof or in connection herewith,  then, the severance benefits provided under Section 3.2 and Section 3.3 (the “Severance Benefits”) are not meant to replace or supersede any similar severance benefits provided under the Sirius Group Severance and Change in Control Plan or any employment agreement, arrangement or award agreement or any other similar contractual arrangement (“Other Severance Benefits”) and the Severance Benefits provided under this Agreement are not intended to result in any duplicative benefits to the Holder and this Agreement shall be administered accordingly.  For the avoidance of doubt, this Section 7.1 is not meant to impinge or interfere with the Company’s ability to require the Holder to follow or adhere to any steps or requirements under this Agreement or Other Severance Benefits to obtain severance benefits contemplated thereunder (e.g., executing any releases, complying with any restrictive covenants, etc.).

7.2.                            Withholding Taxes. Subject to Section 5.5 of the Plan, as a condition precedent to the issuance or delivery of the Common Shares, either (i) the Holder shall, upon request by the Company, pay to the Company such amount as the Company (or an Affiliate) may be required, under all applicable federal, state, local, foreign or other laws or regulations, to withhold and pay over as income or other withholding taxes (the “Required Tax Payments”) with respect to the Award or (ii) the Company (or an Affiliate) may, in its discretion, deduct any Required Tax Payments from any amount then or thereafter payable by the Company (or an affiliate) to the Holder, which may include the withholding of whole Common Shares, which would otherwise be delivered to the Holder having an aggregate Fair Market Value, determined as of the date on which such withholding obligation arises, equal to the Required Tax Payments, in either case in accordance with such terms, conditions and procedures that may be prescribed by the Company.  A determination by the Company to satisfy the Required Tax Payments by withholding Common Shares shall be made by the Committee if the Holder is subject to Section 16 of the Exchange Act.

The Company agrees to use reasonable efforts to effect or obtain any such listing, registration, qualification, consent, approval or other action.

7.4.                            Award Confers No Rights to Continued Employment.

7.16.                     Unfunded Status of Awards; No Trust of Fund Created. The Plan is intended to constitute an “unfunded” plan for certain incentive awards.
