I. Purpose

The Organization and Compensation Committee (the “Committee”) is a standing committee of the Board of Directors (the “Board”) of Aon plc (the “Company”). The purpose of the Committee is to assist the Board in carrying out its overall responsibilities with regard to executive compensation, including oversight of the determination and administration of the Company’s compensation philosophy, policies, programs and plans for executive officers and non-employee directors.

II. Membership, Structure and Organization

1. Members. The membership of the Committee shall be determined by the Board and shall consist of three (3) or more directors who are not members of management of the Company. The Board shall also appoint a chairperson of the Committee from the membership of the Committee. All of the members of the Committee shall meet the independence requirements of the New York Stock Exchange (the “NYSE”) and any other applicable laws and regulations, and the requirements for (i) a “non-employee director” contained in Rule 16b-3 under the Securities Exchange Act of 1934 and (ii) an “outside director” for purposes of Section 162(m) of the Internal Revenue Code of 1986, as amended. The Board may remove any member from the Committee at any time.

2. Meetings. The Committee shall meet as frequently as it determines, but not fewer than three (3) times per calendar year. Meetings of the Committee may be held in-person, telephonically, or through any other method of electronic communication. The Committee may elect to meet from time to time in executive session at its discretion.

3. Delegation of Authority. To the extent permitted by applicable law and the listing standards of the NYSE, the Committee may establish subcommittees consisting of one or more members or other independent directors, and may delegate to such subcommittees and management power and authority to carry out such duties as the Committee may delegate.

4. Resources. The Committee has the authority, in its sole discretion, to retain or obtain the advice of outside advisors, including compensation consultants, legal counsel or other experts (collectively, “Advisors”), as it deems appropriate, and shall be directly responsible for the appointment, termination, compensation and oversight of the work of any Advisor retained by the Committee. The Committee shall receive appropriate funding from the Company, as determined by the Committee, for the payment of compensation to any Advisors retained by the Committee. The Committee shall have the sole authority to approve an Advisor’s retention terms, including limitations on the Advisor’s ability to perform work for the Company or management, except as approved by the Chairperson of the Committee and in support of the purpose and responsibilities of the Committee under this charter. The Committee shall assess any conflicts of interests with an Advisor and may select an Advisor only after taking into consideration factors relevant to such Advisor’s independence, including any factors required to be considered under the listing standards of the NYSE and any other applicable law.

5. Charter. The Committee shall annually review and reassess the adequacy of this charter and recommend any proposed changes to the Board for approval.

6. Agenda, Minutes and Reports. The Chairperson of the Committee shall be responsible for setting the agendas for meetings. The agenda and information concerning the business to be conducted at each Committee meeting shall, to the extent practicable, be communicated to members sufficiently in advance of each meeting to permit meaningful review. The Chairperson of the Committee will report regularly to the Board on the Committee’s activities, findings and recommendations, including the results of the Committee evaluation. The report to the Board may take the form of a written or oral report by the Chairperson or by any other member of the Committee designated by the Chairperson to make such report.
