Agreement and Plan of Merger and Reorganization approved by Aon&#146;s shareholders on March&nbsp;16, 2012. As a result of the Reorganization, Aon became a subsidiary of the Company, and each share of common stock of Aon was converted into one

March&nbsp;29, 2019. The Plan was subsequently amended in September 2021, and then amended and restated again effective June&nbsp;16, 2023. This amendment and restatement was approved by the Board on April&nbsp;18, 2025, and is effective upon
approval of the Company&#146;s shareholders at the June&nbsp;27, 2025 meeting. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">SECTION 2 Defined Terms </P>

under the separation pay exemption will be made without regard to any payments which qualify as short-term deferrals. To the extent any amounts under this Plan are payable by reference to an Award holder&#146;s &#147;termination of employment,&#148;
such term will be deemed to refer to the Award holder&#146;s &#147;separation from service,&#148; within the meaning of Section&nbsp;409A of the Code. Notwithstanding any other provision in this Plan, if an Award holder is a &#147;specified

compensation, within the meaning of Section&nbsp;409A of the Code, (ii)&nbsp;is payable upon the Award holder&#146;s separation from service and (iii)&nbsp;under the terms of this Plan would be payable prior to the
