merger is expected to deliver $800&nbsp;million of cost synergies and be accretive to both adjusted EPS and free cash flow.&#148;<SUP STYLE="font-size:85%; vertical-align:top">2</SUP> The ISS report also highlights that, &#147;AON and WLTW have

estimates exclude any potential revenue synergies. None of the synergies or other cost reductions statements, or the earnings per share or cash flow accretion statements, should be construed as a profit forecast or interpreted to mean that the

period. </P></TD></TR></TABLE>

Statements </B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">This communication contains certain statements that are forward-looking, as that term is defined in the Private Securities Litigation
Reform Act of 1995. 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. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Although management believe 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 and/or Willis Towers Watson securities and on Aon and/or
Willis Towers Watson&#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 proposed
consummation of or failure to consummate the proposed combination on the market price of Aon and/or Willis Towers Watson securities, significant transaction and integration costs or difficulties in connection with the proposed combination and/or
unknown or inestimable liabilities, pending or 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. </P>
