Subject: Terms of Employment
Dear Pat,
This letter agreement sets forth the terms of your continued employment by Mercer Consulting Group, Inc. (“Mercer”) as its President and Chief Executive Officer. This position reports to the President and Chief Executive Officer (the “Chief Executive Officer”) of Marsh & McLennan Companies, Inc. (“Marsh McLennan”, and together with its subsidiaries and affiliates, the “Company”). Your current principal work location is in New York, NY. The terms of this letter agreement are effective as of April 1, 2024.
1. Duties and Responsibilities
You will continue to devote all of your attention and time during working hours to the affairs and business of Mercer 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 Marsh McLennan and any corporation, partnership, joint venture, limited liability company, or other entity in which Marsh McLennan 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 Marsh McLennan.
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 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.

b. Vacation: You are entitled to six (6) weeks of vacation annually, in accordance with our Company policy.
c. Annual Bonus: You are eligible to participate in the senior executive annual bonus program on the terms set forth on Exhibit A. Bonus awards are discretionary and may be paid in the form of cash, deferred cash or Marsh McLennan stock units, or a combination thereof. 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 in compliance with this agreement and without having resigned, 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 Marsh McLennan’s 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 Marsh McLennan’s 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 Marsh McLennan Board of Directors (“Compensation Committee”) as set forth in the award agreement and in Marsh

McLennan’s 2020 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. Benefit Programs: You and your eligible family members will continue to have the opportunity to participate in the employee benefit plans, policies and programs provided by Marsh McLennan, on such terms and conditions as are generally provided to similarly situated employees of Mercer 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. Please be aware that nothing in this letter agreement shall limit Marsh McLennan’s ability to change, modify, cancel or amend any such policies or plans. In addition, you will continue to be eligible to participate in the Marsh McLennan 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 Marsh & McLennan Companies, Inc. Senior Executive Severance Pay Plan (the “Senior Executive Severance Plan”).

In the event that 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. Upon the termination of your employment for any reason, you shall immediately resign, as of your date of termination, from all positions that you then hold with any member of the Affiliated Group.

c. During the term of this letter agreement, and, subject to any other business obligations that you may have, following your date of termination, you agree to assist the Affiliated Group in the investigation and/or defense of any claims or potential claims that may be made or threatened to be made against any member of the Affiliated Group, including any of their officers or directors (a “Proceeding”), and will assist the Affiliated Group in connection with any claims that may be made by any member of the Affiliated Group in

h. Section 409A. The provisions of this Section 8(h) 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. In furtherance of the objective of this Section 8(h), to the extent that any regulations or other guidance issued under Section 409A would result in your being subject to payment of taxes, interest or penalties under Section 409A, you and the Company agree to use our best efforts to amend this letter agreement and any other plan, award, arrangement or agreement between you and the Company in order to avoid or limit the imposition of any such taxes, interest or penalties, while maintaining to the maximum extent practicable the original intent of the applicable provisions. This Section 8(h) does not guarantee that you will not be subject to taxes, interest or penalties under Section 409A with respect to compensation or benefits described or referenced in this letter agreement or any other plan, award, arrangement or agreement between you and the Company.
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.
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”):
1) if the Relevant Plan does not specify a period or provides for a period of more than 90 days for the completion of an Employment-Related Action, then the period for completion of the Employment-Related Action will be the period specified by the Company, which shall be no longer than 90 days following the event otherwise triggering the right to payment; and

2) if the period for the completion of an Employment-Related Action includes the January 1 next following the event otherwise triggering the right to payment, then the payment shall be made or commence following the completion of the Employment-Related Action, but in no event earlier than that January 1.
i. Withholding Requirements. All amounts paid or provided to you under this
letter agreement shall be subject to any applicable income, payroll or other tax
withholding requirements.
Please acknowledge your agreement with the terms of this letter agreement by signing and dating this letter agreement and the Non-Competition and Non-Solicitation Agreement and providing a copy of each to me. (Emailing scanned copies is sufficient.)
Sincerely,
/s/ John Q. Doyle
