This position currently reports to the President and Chief Executive Officer (the “Chief Executive Officer”) of Xxxxx & XxXxxxxx Companies, Inc. (“Xxxxx & McLennan Companies,” and together with its subsidiaries and affiliates, the “Company”) and serves as a member of the Xxxxx & XxXxxxxx Companies Executive Committee. The terms of this letter agreement are effective as of July 1, 2019.

1. Duties, Responsibilities and Place of Work

You will devote all of your attention and time during working hours to the affairs and business of Marsh and the Company and use your best efforts to perform such duties and responsibilities as shall be reasonably assigned to you by the Chief Executive Officer and are consistent with your position. In addition, you agree to serve, without additional compensation, as an officer and director for any member of the Affiliated Group. For purposes of this letter agreement, the term “Affiliated Group” means Xxxxx & XxXxxxxx Companies and any corporation, partnership, joint venture, limited liability company, or other entity in which Xxxxx & McLennan Companies has a 10% or greater direct or indirect interest. Except for those boards or committees set forth on Exhibit A, if any, you may not serve on corporate, civic or charitable boards or committees without the prior written consent of Xxxxx & XxXxxxxx Companies.

You will work such hours as are necessary for the proper performance of your duties under this letter agreement; you acknowledge that your working time is not measured or pre-determined and that you are a managing executive for the purposes of the U.K. Working Time Regulations, 1998.

The Company requires that your principal place of work is a Company office in London, U.K. and you will be expected to conduct the majority of your client and/or customer meetings from the London office. You will be required to travel and work at other places (whether

inside or outside the U.K.) for such periods as the Company may from time to time require on either a temporary or an indefinite basis.

For purposes of the U.K. Employment Rights Xxx 0000, the periods of your employment with Jardine Xxxxx Xxxxxxxx Group plc and its subsidiaries and predecessors will count as part of your continuous employment with the Company, and accordingly the date upon which your period of continuous employment began is June 1, 1980.

2.    Compensation and Benefits

Your compensation and benefits are as set forth below and in Exhibit A.

a. Annual Base Salary: You will receive an annual base salary of the amount set forth on Exhibit A, payable in installments in accordance with Xxxxx’x or the Company’s payroll procedures in effect from time to time. Your base salary includes compensation for all time worked, as well as appropriate consideration for sick days, personal days, and other time off in accordance with Marsh and relevant Company policies. Your base salary will be considered for adjustment in succeeding years as part of the Company’s normal senior performance management process.

b. Vacation: In addition to the U.K. bank and public holidays that are observed in accordance with Company policy, you are entitled to 40 working days of vacation annually, which will be administered in accordance with Company policy, at times that are agreed in advance. You will, if requested, take any accrued vacation during any period of notice to terminate your employment.

c. Annual Bonus: You are eligible for an annual bonus on the terms set forth on Exhibit A. Bonus awards are discretionary and will be paid in cash. Except as provided in this paragraph and in Section 3(a), to qualify for an annual bonus, you must remain continuously and actively employed by the Company, without having tendered or been given notice of termination, through the date of the bonus payment, in accordance with the terms and conditions of the award. The annual bonus shall be paid no later than March 15 of the year following the year for which such bonus is earned. In the event of your Permanent Disability (as defined below) or death, the Company shall pay you (or your estate in the case of death) a prorated target annual bonus for the year in which your termination occurs based on the portion of the year elapsed as of the date of your termination. Any such bonus amount shall be paid within 30 days of your death. In the event of your Permanent Disability, your prorated annual bonus payment is conditioned upon, and subject to, your execution and delivery to the Company within 30 days of the date of such event a valid confidential waiver and release of claims agreement (including restrictive covenants) in a form satisfactory to the Company (the “Release”) and such Release has become irrevocable as provided therein (the “Release Effective Date”). Payment of any such annual bonus amount shall then be paid within 30 days following the Release Effective Date, but in no event later than March 15 of the year following the year for which such bonus is earned.

As used in this letter agreement, “Permanent Disability” will be deemed to occur when it is determined (by Xxxxx & McLennan Companies’ disability carrier for the primary long-term disability plan or program applicable to you because of your employment with the Company) that you are unable to engage in any substantial gainful activity by reason of any medically

determinable physical or mental impairment that can be expected to result in death or can be expected to last for a continuous period of not less than 12 months.

d. Annual Long-Term Incentive Compensation: You are eligible to participate in Xxxxx & McLennan Companies’ long-term incentive program with a target long-term incentive compensation award as set forth on Exhibit A. Long-term incentive awards are discretionary and are governed by terms and conditions approved by the Compensation Committee of the Xxxxx & XxXxxxxx Companies Board of Directors (“Compensation Committee”) as set forth in the award agreement and in Xxxxx & McLennan Companies’ 2011 Incentive and Stock Award Plan (or other plan under which the long-term incentive award is granted). In accordance with Company practice, you may be required to enter into a “Restrictive Covenants Agreement” in connection with long-term incentive awards.

e. Special Restricted Stock Unit Award: On the first calendar day of the month following the closing of the acquisition of Jardine, Xxxxx Xxxxxxxx Group, plc (“JLT”) by the Company (the “Acquisition”), you will be granted an award of restricted stock units (“RSUs") as set forth on Exhibit A in lieu of any JLT Deferred Bonus Scheme award. Your award will be converted from the dollar value of the grant into RSUs based upon the average of the high and low sales prices of a share of Xxxxx & XxXxxxxx Companies common stock on the New York Stock Exchange one trading day prior to the effective date of the grant. One third of the RSUs will vest on each of the first three anniversaries of the grant date, subject to your continued employment, will fully vest in the event the Company terminates your employment without cause and will be subject to terms and conditions approved by the Compensation Committee as set forth in the award agreement and in Xxxxx & XxXxxxxx Companies’ 2011 Incentive and Stock Award Plan (or any successor plan under which the award is granted). You will receive additional information regarding these RSUs, including the terms and conditions of the award, shortly after the award is granted.

f. Annual Retention Awards. You will be eligible for three annual retention awards (each, an “Annual Retention Award”) as set forth herein and in the amount on Exhibit A. On each of the first three anniversaries of the Acquisition, provided that you remain continuously and actively employed by the Company, with neither the Company nor you having tendered notice of termination of employment, an Annual Retention Award will vest and be paid within 30 days after such anniversary. In the event the Company provides you notice of your termination of employment without cause (as defined in the Senior Executive Severance Plan) prior to the third anniversary of the Acquisition, the Company will pay you the Annual Retention Award that is scheduled to vest on the next anniversary of the Acquisition, conditioned on, and subject to, your execution and delivery to the Company within 30 days following the date of your termination of employment a Release and such Release has become irrevocable as provided therein. Any such Annual Retention Award shall be paid within 30 days following such Release Effective Date, and you will not be eligible for any further Annual Retention Awards. In the event you provide notice of your termination of employment, or your employment terminates for any reason other than a termination of employment by the Company without cause, any unpaid Annual Retention Award will be forfeited and you will not be eligible for any further Annual Retention Awards.

g. Benefit Programs: You and your eligible family members will have the opportunity to participate in the employee benefit plans, policies and programs provided by Xxxxx & XxXxxxxx Companies, on such terms and conditions as are generally provided to similarly

situated employees of Marsh and the Company. These plans may include retirement, savings, medical, life, disability, and other insurance programs as well as an array of work/life effectiveness policies and programs. Provision of such benefits is subject always to relevant plan rules and will not limit the Company’s ability to terminate your employment pursuant to the terms of this letter agreement. Please be aware that nothing in this letter agreement shall limit Xxxxx & McLennan Companies’ ability to change, modify, cancel or amend any such policies or plans. In addition, you will be entitled to the benefits set forth on Exhibit A and you will be eligible to participate in the Xxxxx & XxXxxxxx Companies Executive Financial Services Program, as in effect from time to time.

3. Termination of Employment

a. You have been designated as a “Key Employee” under the Xxxxx & McLennan Companies, Inc. Senior Executive Severance Pay Plan (the “Senior Executive Severance Plan”). In the event that your employment with the Company terminates for any reason, the Senior Executive Severance Plan in effect at the time of your termination will exclusively govern the terms under which you may be eligible to receive severance and/or other transition benefits from the Company; provided that any payments to which you may be entitled under the Senior Executive Severance Plan will be made within 60 days after the date of your termination of employment (as determined under Section 8(i) below). For the avoidance of doubt, any entitlement to severance payments under Article 5 of the Senior Executive Severance Plan shall be reduced by any amounts you receive pursuant to Sections 3(b) and 3(d) below. If you are entitled to receive severance benefits under Article 5 of the Senior Executive Severance Plan, the Company shall also pay you the earned annual bonus, if any, for the calendar year that preceded your termination to the extent not theretofore paid.

b. The Company may on its own behalf and on behalf of Marsh terminate your employment at any time by giving you twelve months’ notice in writing, or by making you a payment of base salary in lieu of notice within 60 days after your termination of employment (subject to Section 8(i) below). Your employment may however be terminated for cause (as defined in the Senior Executive Severance Plan) immediately without notice or payment in lieu. You may terminate your employment by giving the Company twelve months’ written notice of termination.

c. In the event you provide notice to the Company of your termination of employment after the first anniversary of the Acquisition and before the third anniversary of the Acquisition, your termination of employment will be treated as a termination by the Company without cause exclusively for purposes of your outstanding equity-based awards and the Senior Executive Severance Plan (with payments thereunder made in accordance with Section 3(a)). For the avoidance of doubt, this provision shall not apply to the Annual Retention Awards described in Section 2(f).

d. At any time during any period of notice of termination, you may be suspended on full pay and benefits, and the Company shall be under no obligation to provide you any work or to assign you any duties. You acknowledge and agree that you may during such period of paid suspension be excluded from Company premises, removed from directorships and required to refrain from business contact with clients, officers, agents or employees of the Company.

The provisions of this Section 8(i) will only apply if and to the extent required to avoid the imposition of taxes, interest and penalties on you under Section 409A of the Internal Revenue Code of 1986, as amended (“Section 409A”). Section 409A applies to nonqualified deferred compensation which exists if an individual has a “legally binding right” to compensation that is or may be payable in a later year.

Furthermore, and notwithstanding any contrary provision in this letter agreement or any other plan, award, arrangement or agreement between you and the Company, to the extent necessary to avoid the imposition of taxes, interest and penalties on you under Section 409A, if at the time of the termination of your employment you are a “specified employee” (as defined in Section 409A), you will not be entitled to any payments upon termination of employment until the first day of the seventh month after the termination of employment and any such payments to which you would otherwise be entitled during the first six months following your termination of employment will be accumulated and paid without interest on the first day of the seventh month after the termination of employment. For purposes of this letter agreement and the Senior Executive Severance Plan, you shall be deemed to have had a termination of employment at such time when you have experienced a “separation from service” for purposes of Section 409A (as defined in Treasury Regulations Section 1.409A-1(h)).

Furthermore, and notwithstanding any contrary provision in this letter agreement or in any other plan, award, arrangement or agreement between you and the Company that: (i) provides for the payment of nonqualified deferred compensation that is subject to Section 409A; and (ii) conditions payment or commencement of payment on one or more employment-related actions, such as the execution and effectiveness of a release of claims or a restrictive covenant (each an “Employment-Related Action”) (any such plan, award, arrangement or agreement is a “Relevant Plan”):

triggering the right to payment; and
