Term

2.1Employment Period. The initial term of the Executive’s employment under this Agreement (the “Initial Term”) shall commence on the Effective Date and shall continue through August 25, 2008. Thereafter, this Agreement shall automatically renew for successive one (1) year terms (each, a “Renewal Term”) unless either party sends a notice of termination to the other party in accordance with Section 6.2 hereof at least ninety (90) days prior to the expiration of the Initial Term or Renewal Term, as the case may be. The Initial Term, together with any and all Renewal Terms, if any, are the “Term.”

2.2Payment Due to Non-Renewal by the Company. If, prior to the Executive’s sixty-second (62nd) birthday, the Company sends a notice of termination of the Term to the Executive as provided in Section 2.1 hereof, and after the expiration of the Term the Executive’s employment is terminated (A) by the Company without Cause (as defined in Section 5.1 hereof) or due to death or Disability (as defined in Section 5.4 hereof) or (B) by the Executive for any reason, then the Company shall pay to the Executive, in a lump sum within thirty (30) days of the effective date of such termination of employment, a cash amount equal to the sum of (x) the Executive’s then-current Base Salary (as defined in Section 3.1 hereof) and (y) the average annual bonus (as described in Section 3.2 hereof) actually paid to the Executive during the three (3) years immediately prior to the termination. In addition, if at any time the Company sends a notice of termination of the Term to the Executive as provided in Section 2.1 hereof, and after the expiration of the Term the Executive’s employment is terminated (A) by the Company without Cause (as defined in Section 5.1 hereof) or due to death or Disability (as defined in Section 5.4 hereof) or (B) by the Executive for any reason, then (a) the Company shall also pay to the Executive the Accrued Obligations (as defined in Section 5.5(a) hereof) within thirty (30) days of the effective date of such termination and (b) all unvested equity awards (which as used in this Agreement include stock options) held by the Executive as of the date of termination that were granted to the Executive pursuant to Sections 3.3 and 3.4 hereof shall immediately fully vest as of the date of termination.

- 2 -

shall preclude the Executive from thereafter receiving any payment provided for (i) in Article 5 hereof or (ii) under any separation or severance plan, program, agreement or other arrangement in which the Executive is a participant or a party.

ARTICLE3

Compensation

As compensation and consideration for the performance by the Executive of his obligations under this Agreement, during the Term the Executive shall be entitled to the compensation and benefits set forth in this Article 3 (collectively, “Compensation”) (subject, in each case, to the provisions of Article 5 hereof).

3.1Base Salary. The Executive shall receive an annual base salary (“Base Salary”) of $1.0 million. The Base Salary shall be reviewed at least annually by the Board of Directors of the Company (the “Board”) and may be increased (but not decreased) in the sole discretion of the Board. If the Executive’s Base Salary is increased, the increased amount shall thereafter be the Base Salary. The Base Salary shall be payable in installments, consistent with the Company’s payroll procedures in effect from time to time. At the end of the first payroll period that commences after the Effective Date, the Executive shall also receive a lump-sum payment (subject to appropriate deductions) equal to the difference between the Base Salary and the Executive’s base salary in effect immediately prior to the Effective Date prorated for the period from January 1, 2005 to the Effective Date.

3.2Annual Bonus. In addition to Base Salary, the Executive shall be eligible to participate throughout the Term in such annual bonus plans and programs (“Annual Bonus Programs”), as may be in effect from time to time in accordance with the Company’s compensation practices and the terms and provisions of any such plans or programs. The Executive’s annual bonus opportunity will range between one hundred fiftypercent(150%) and three hundred percent (300%) of his Base Salary. The actual bonus amounts will be determined by the Committee based on the achievement of entity and individual performance goals, with bonuses in the upper portion of the annual bonus opportunity range being earned only for superior achievement of such performance goals. Based on 2005 performance up to the Effective Date, the Company expects the Executive’s bonus for 2005 to be in the upper portion of the annual bonus opportunity range. The annual bonus shall be paid entirely in cash.

3.3Long-Term and Equity Compensation. The Executive shall also be eligible to participate in the Company’s long-term incentive compensation plans (including its equity-compensation plans) applicable to MMC’s senior executive officers. The specific awards under these plans will be made by the Committee in its sole discretion, commensurate with the Executive’s position as Chairman and Chief Executive Officer, Marsh. Notwithstanding the foregoing, the Committee shall each year grant to the Executive long-term incentive compensation comprised of (i) a restricted stock or restricted stock unit award and/or (ii) a stock option or stock-settled stock appreciation right, with a combined grant-date target value between

- 3 -

one-time and three-times the Executive’s Base Salary, as determined by the Committee, and provided further that neither the restricted stock nor the stock option portion of the award shall comprise more than two-thirds of the total grant-date target value of the award. Each restricted stock award will vest three years from the grant date, while one-third of each stock option award will vest on each of the first, second and third anniversaries of the grant date.

3.4Initial Retention Award. The Executive acknowledges that he has received an initial retention award under the 2000 Senior Executive Incentive and Stock Award Plan (the “Initial Retention Award”) of restricted stock with a grant-date value of $1.6 million. The restricted stock award will vest three years from the grant date. Additional terms and conditions of the award shall be determined by the Committee and contained in the grant agreements, provided that no such term or condition shall be inconsistent with any provision of this Agreement.

3.5Benefit Plans. The Executive and the Executive’s spouse and eligible dependents, as the case may be, shall be eligible to participate in employee benefit and fringe benefit plans and programs provided by the Company, including but not limited to pension, life insurance, health, dental and disability plans and programs, on terms and conditions generally applicable to executives of the Company. Nothing herein shall limit the Company’s ability to change, modify, cancel or amend any such plans. The Executive shall be eligible to participate in the Company’s retiree medical program as may be in effect from time to time.

3.6Executive Financial Services Program. The Executive shall be eligible to participate in the MMC Financial Services Program as in effect from time to time.

The Company will reimburse the Executive for reasonable business-related expenses incurred by him in connection with the performance of his duties hereunder during the Term, subject, however, to the Company’s written policies relating to business-related expenses as in effect, from time to time, during the Term, a copy of which has previously been provided to the Executive.

3.8Vacation. The Executive shall be entitled to paid vacation in accordance with the Company’s policy in effect from time to time during the Term.

6.This General Release does not waive rights or claims that may arise under the ADEA after the date Executive signs this General Release. To the extent barred by the OWBPA, the covenant not to sue contained in Section 2, above, does not apply to claims under the ADEA that challenge the validity of this General Release.
