Agreement provides that, concurrently with or immediately following the effective date of the previously announced transaction (as described in Aon UK&#146;s Proxy Statement on Schedule 14A, dated and filed with the U.S. Securities and Exchange
Commission (the &#147;SEC&#148;) on December&nbsp;20, 2019, the &#147;Reorganization&#148;) that will change the jurisdiction of incorporation of the parent company of Aon UK from the United Kingdom to Ireland and result in a new publicly held
parent company incorporated in Ireland (&#147;Aon Ireland&#148;), Aon UK will assign, and Aon Ireland will assume, all of its rights and obligations under the Business Combination Agreement (the &#147;Required Assignment&#148;). </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Under the terms of the Business Combination Agreement, the Combination will be implemented by means of a court-sanctioned scheme of arrangement under Chapter

shares, nominal value $150.00 per share, of Aon Ireland (&#147;Aon Ireland Shares&#148;) in exchange for each ordinary share of WTW held by such holders (the &#147;Scheme Consideration&#148;) and (b)&nbsp;WTW equity awards will be treated as set
forth in the Business Combination Agreement, such that each unexercised WTW option, restricted stock unit, performance stock unit, phantom stock unit or other equity award that is outstanding immediately prior to the Effective Time will be converted
into a corresponding award relating to Aon Ireland Shares, with such number of Aon Ireland Shares subject to such award and, if applicable, the exercise price applicable to such award determined in accordance with the formulas in the Business
Combination Agreement. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The Business Combination Agreement contemplates a possible second-step merger, following consummation of the Combination, pursuant

Forward-looking statements are prospective in nature and are not based on historical facts, but rather on current expectations of management about future events. Forward-looking statements can often, but not always, be identified by the use of words
such as &#147;plans,&#148; &#147;expects,&#148; &#147;is subject to,&#148; &#147;budget,&#148; &#147;scheduled,&#148; &#147;estimates,&#148; &#147;forecasts,&#148; &#147;potential,&#148; &#147;continue,&#148; &#147;intends,&#148;
&#147;anticipates,&#148; &#147;believes&#148; or variations of such words, and statements that certain actions, events or results &#147;may,&#148; &#147;could,&#148; &#147;should,&#148; &#147;would,&#148; &#147;might&#148; or &#147;will&#148; be
taken, occur or be achieved. Although management believes that the expectations reflected in these forward-looking statements are reasonable, it can give no assurance that these expectations will prove to be correct. By their nature, forward-looking
statements involve risks and uncertainties because they relate to events and depend on circumstances that will occur in the future. There are a number of factors that could cause actual results and developments to differ materially from those
expressed or implied by the forward-looking statements. Such factors include, but are not limited to, the possibility that the proposed combination will not be consummated, failure to obtain necessary shareholder or regulatory approvals or to
satisfy any of the other conditions to the proposed combination, adverse effects on the market price of Aon UK, Aon Ireland and/or WTW securities and on Aon UK&#146;s, Aon Ireland&#146;s and/or WTW&#146;s operating results for any reason, including,
without limitation, because of the failure to consummate the proposed combination, the failure to realize the expected benefits of the proposed combination (including anticipated revenue and growth synergies), the failure to effectively integrate
the combined companies following consummation of the proposed combination, negative effects of an announcement of the proposed combination, changes in global, political, economic, business, competitive, market and regulatory forces, future exchange
and interest rates, changes in tax laws, regulations, rates and policies, future business acquisitions or disposals, or any announcement relating to the consummation of or failure to consummate the proposed combination on the market price of Aon UK,
Aon Ireland and/or WTW securities, significant transaction and integration costs or difficulties in connection with the proposed combination and/or unknown or inestimable liabilities, potential litigation associated with the proposed combination,
the potential impact of the announcement or consummation of the proposed combination on relationships, including with suppliers, customers, employees and regulators, and general economic, business and political conditions (including any epidemic,
pandemic or disease outbreak) that affect the combined companies following the consummation of the proposed combination. The factors identified above are not exhaustive. Aon UK, Aon Ireland, WTW and their subsidiaries operate in a dynamic business

any party acting in concert with either of them must also be disclosed by no later than 12 noon (Eastern time) in respect of the relevant securities of Aon UK, Aon Ireland and WTW on the business day following the date of the relevant transaction.
Interests in securities arise, in summary, when a person has a long economic exposure, whether conditional or absolute, to changes in the price of securities. In particular, a person will be treated as having an interest by virtue of the ownership
or control of securities, or by virtue of any option in respect of, or derivative referenced to, securities. Terms used in this paragraph should be read in light of the meanings given to those terms in the Irish Takeover Rules. If you are in any
doubt as to whether or not you are required to disclose dealings under Rule 8 of the Irish Takeover Rules, consult with the Irish Takeover Panel&#146;s website at www.irishtakeoverpanel.ie or contact the Irish Takeover Panel by telephone on +353 1
