ALLIED WORLD ASSURANCE COMPANY HOLDINGS, AG

2012 OMNIBUS INCENTIVE COMPENSATION PLAN

RSU AWARD AGREEMENT

This RSU Award Agreement (this “RSU Agreement”) sets forth the terms and conditions of an award (this “Award”) consisting of restricted stock units that settle in Shares and/or cash (the “RSUs”) granted to you under the Allied World Assurance Company Holdings, AG 2012 Omnibus Incentive Compensation Plan (the “Plan”). Allied World Assurance Company Holdings, AG (the “Company” or “Allied World”), and you agree as follows:

1. The Plan. This Award is made pursuant to the Plan, the terms and conditions of which are incorporated in this RSU Agreement. Capitalized terms used in this RSU Agreement (including the attached Glossary of Terms) that are not defined in this RSU Agreement or in the attached Glossary of Terms shall have the meanings set forth in the Plan. In the event of a conflict or inconsistency between the terms and provisions of the Plan and the provisions of this RSU Agreement (including the attached Glossary of Terms), the Plan shall govern and control.

2. Award. The number of RSUs subject to this Award (i.e., the aggregate Cash-Settled RSUs and Share-Settled RSUs) is set forth at the end of this RSU Agreement. Each RSU constitutes an unfunded and unsecured promise by Allied World to deliver (or cause to be delivered) to you, subject to the terms of this RSU Agreement, one Allied World Share (or cash equal to the Fair Market Value thereof) on the applicable Delivery Date as provided herein. Until such delivery of Shares, except as otherwise provided in Section 3, you have only the rights of a general unsecured creditor, and no rights as a shareholder of Allied World. THIS AWARD IS SUBJECT TO ALL TERMS, CONDITIONS AND PROVISIONS OF THE PLAN AND THIS RSU AGREEMENT, INCLUDING, WITHOUT LIMITATION, THE CHOICE OF FORUM PROVISIONS SET FORTH IN SECTION 15.

3. Vesting and Delivery.

(a) Vesting. Except as provided in this Section 3 and in Sections 4 and 6, 25% of the RSUs subject to this Award shall vest on each of the first, second, third and fourth anniversaries of the Date of Grant specified at the end of this RSU Agreement (each, a “Vesting Date”). Unless the Committee determines otherwise, and except as provided in this Section 3 or in Section 6, if your employment terminates for any reason prior to a Vesting Date, your rights in respect of all of your then unvested RSUs shall terminate, and no Shares and/or cash shall be delivered in respect of such RSUs.

(b) Delivery. Except as provided in this Section 3 and in Sections 4, 6 and 9, on each applicable Delivery Date, the Company shall:

(i) issue or transfer to you, or cause to be issued or transferred to you, the number of Shares underlying the Share-Settled RSUs that vested (if any) on the applicable Vesting Date, and shall either (A) deliver, or cause to be delivered, to you a certificate or certificates therefor, registered in your name; or (B) cause such Shares to be credited to your account at a third-party stock plan administrator as may be arranged for by the Company or the Committee from time to time for purposes of the administration

of outstanding Awards under the Plan. You shall be deemed the beneficial owner of the Shares at the close of business on the applicable Vesting Date and shall be entitled to any dividend or distribution that has not already been made with respect to such Shares if the record date for such dividend or distribution is after the close of business on such Vesting Date; and

(ii) transfer to you, or cause to be transferred to you, an amount of cash equal to the aggregate Fair Market Value of the Shares underlying the Cash-Settled RSUs that vested (if any) on the applicable Vesting Date, determined as of such Vesting Date.

(c) Death or Termination Due to Disability. Notwithstanding any other provision of this RSU Agreement, but subject to Section 6(b), if you die or are terminated due to Disability prior to any Vesting Date, and provided your rights in respect of your RSUs have not previously terminated, then in lieu of delivery on the applicable Delivery Date and any subsequent Delivery Dates, the Shares and /or cash corresponding to your outstanding RSUs shall be delivered to you or your estate or beneficiaries, as applicable, as soon as reasonably practicable after the date of your death or termination due to Disability, as applicable, and after such documentation, as may be requested by the Company or third-party stock plan administrator, is provided to the Company or such third-party stock plan administrator, as applicable, but in no event later than March 15 of the calendar year immediately following the year in which such death or termination occurred. Such issuance or transfer or delivery of cash shall be on the terms set forth in Section 3(b) applicable to Shares and/or cash deliverable on a regularly scheduled Delivery Date. Shares and/or cash delivered pursuant to this Section 3(c) as a result of your termination due to Disability shall remain subject to repayment under Section 6(b) until the regularly scheduled Delivery Date for such Shares and/or cash. Except as otherwise provided in this Section 3(c), all other conditions of this RSU Agreement shall continue to apply.

(d) Termination without Cause or for Good Reason under Employment Agreement. Notwithstanding any other provision of this RSU Agreement or the Plan, in the event that you are party to an employment agreement with the Company that provides that the vesting of any portion of your RSUs accelerates upon a termination without cause or for good reason (as such terms are defined in such employment agreement), then the provisions of such employment agreement shall govern, including the definitions of “cause” and “good reason”. In the event of such accelerated vesting, in lieu of delivery on the applicable Delivery Date, the RSUs payable under this Section 3(d) shall be settled in Shares and/or cash as soon as reasonably practicable following such termination without cause or for good reason, but in no event later than March 15 of the calendar year following such termination.

(e) Change of Control. Notwithstanding any other provision of this RSU Agreement or the Plan, in the event of a Change of Control, the change of control provisions of any employment agreement between you and the Company shall govern, including the definition of “change of control” as provided in such agreement; provided, however, that, notwithstanding the foregoing, in the event of a Change of Control that satisfies the definition as provided in the Plan but does not satisfy the definition of “change of control” as provided in such employment agreement, the terms and conditions of Section 8 of the Plan shall govern. In the event the vesting of your RSUs accelerates pursuant to such employment agreement or if the vesting of

-2-

your RSUs accelerates pursuant to Section 8 of the Plan upon a Qualifying Termination within two years following a Change of Control, in lieu of delivery on the applicable Delivery Date, the RSUs payable under this Section 3(e) shall be settled in Shares and/or cash as soon as reasonably practicable following the date on which such RSUs vest, but in no event later than March 15 of the calendar year following the calendar year in which such RSUs vested.

4. Termination of RSUs and Non-Delivery of Shares.

(a) Unless the Committee determines otherwise, and except as provided in Sections 3 and 6, your rights in respect of your outstanding RSUs shall immediately terminate, and no Shares and/or cash shall be delivered in respect of such RSUs, if at any time prior to a Vesting Date your employment with the Company terminates for any reason, or you are otherwise no longer actively employed by the Company.

(b) Unless the Committee determines otherwise, and except as provided in Sections 3 and 6, your rights in respect of your outstanding RSUs (whether or not vested) shall immediately terminate, and no Shares and/or cash shall be delivered in respect of such RSUs, if at any time prior to a Delivery Date:

By accepting the delivery of Shares and/or cash under this RSU Agreement, you shall be deemed to have represented and certified at such time that you have complied with all the terms and conditions of this RSU Agreement.

(c) Unless the Committee determines otherwise, if a Delivery Date in respect of any of your outstanding RSUs occurs, and Shares and/or cash with respect to such outstanding RSUs would be deliverable under the terms and conditions of this RSU Agreement, except that you have not complied with the conditions or your obligations under Section 4(b)(iv), all of your rights with respect to your outstanding RSUs shall terminate without delivery of Shares or payment of cash with respect thereto. In addition, except as otherwise required by law or with the express prior written consent of the Board, you shall keep the amount of this Award strictly confidential and you expressly agree that any breach of this Agreement to keep such information confidential may result in forfeiture of this Award and/or immediate termination of your employment.

6. Retirement. (a) Notwithstanding any other provision of this RSU Agreement, but subject to Section 6(b), if your Retirement Eligibility Date occurs prior to any Delivery Date, and provided your rights in respect of your RSUs have not previously terminated, then in lieu of delivery on such Delivery Date and any subsequent Delivery Dates, the Shares and/or cash corresponding to your outstanding RSUs shall be delivered to you, as soon as reasonably practicable following your Retirement Eligibility Date, but in no event later than March 15 of the calendar year following your Retirement Eligibility Date. Such issuance or transfer (or delivery of cash in lieu thereof) shall be on the terms set forth in Section 3(b) applicable to Shares deliverable on a regularly scheduled Delivery Date. Shares and/or cash delivered pursuant to this Section 6(a) as a result of your reaching your Retirement Eligibility Date shall remain subject to repayment under Section 6(b) until the regularly scheduled Delivery Date for such Shares and/or cash. Except as otherwise provided in this Section 6(a), all other conditions of this RSU Agreement shall continue to apply.

(b) Without limiting the application of Section 4(b) or Section 4(c), your rights in respect of any outstanding RSUs that become vested solely by reason of a Disability in accordance with Section 3(c) or Retirement Eligibility in accordance with Section 6(a) shall terminate immediately if, following the termination of your employment with the Company by reason of Disability or your reaching your Retirement Eligibility Date and prior to a Delivery Date, you (i) form, or acquire a 5% or greater equity ownership, voting or profit participation interest in, any Competitive Enterprise or (ii) associate in any capacity (including, but not limited to, association as an officer, employee, partner, director, consultant, agent or advisor) with any Competitive Enterprise, in which case no Shares and/or cash otherwise deliverable with respect to such Delivery Date shall be delivered and, to the extent that Shares and/or cash otherwise scheduled to be delivered on such Delivery Date have already been delivered to you on an accelerated basis upon your termination of employment due to Disability or upon your Retirement Eligibility Date, the Company shall be entitled to receive, and you shall be obligated to pay the Company immediately upon demand therefor, the Fair Market Value of the Shares (determined as of such Delivery Date) and the amount of cash (to the extent that cash was delivered to you) delivered with respect to such Delivery Date without reduction for any Shares and/or cash applied to satisfy withholding tax or other obligations in respect of such Shares and/or cash.

-4-

settled portion of this Award shall immediately be terminated, and you shall be required to forfeit or remit to Allied World the difference between any amount paid to you within the one-year period preceding the financial restatement in respect of this Award and the amount that would have been paid to you based on such financial restatement.

(b) You acknowledge and agree that the terms of this Section 7 may be amended or modified by Allied World without your consent to the extent necessary to comply with the requirements of applicable law, including Section 10D of the Exchange Act.

(c) Allied World may affix to Certificates representing Shares issued pursuant to this RSU Agreement any legend that the Committee determines to be necessary or advisable (including to reflect any restrictions to which you may be subject under a separate agreement with Allied World). Allied World may advise the transfer agent to place a stop transfer order against any legended Shares.

11. Successors and Assigns of Allied World. The terms and conditions of this RSU Agreement shall be binding upon, and shall inure to the benefit of, Allied World and its successor entities.

(b) Neither you nor any of your creditors or beneficiaries shall have the right to subject any deferred compensation (within the meaning of Sections 409A and 457A of the Code) payable under this RSU Agreement to any anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, attachment or garnishment.
