YOUR VOTE IS VERY IMPORTANT – PLEASE VOTE THE ENCLOSED PROXY CARD TODAY!

October 30, 2015

Dear Fellow Stockholder,

Towers Watson’s November 18, 2015 Special Meeting of Stockholders is rapidly approaching. We urge you to sign and return your proxy card today to approve our merger of equals (“MOE”) with Willis Group Holdings (“Willis”).

VOTE “FOR” THE TOWERS WATSON/WILLIS MERGER EXPECTED TO CREATE

APPROXIMATELY $4.7 BILLION IN INCREMENTAL VALUE FOR STOCKHOLDERS

The proposed merger with Willis is a unique opportunity to accelerate our long-term strategy. Following the merger, Towers Watson stockholders will have an approximately 49.9% ownership interest in a leading integrated global advisory, broking and solutions firm that is expected to deliver approximately $4.7 billion in total incremental value through a combination of revenue synergies, cost savings and tax efficiencies.

We expect this combination to deliver projected Cash Net Income accretion to Towers Watson stockholders in excess of 25% for calendar year 2016, growing to 45% for calendar year 2018.

COMBINATION EXPANDS CLIENT REACH AND CREATES A

POWERFUL PLATFORM TO DRIVE PROFITABLE GROWTH

We are confident the combination will create a powerful platform to drive profitable growth by:

 

    Expanding client reach across attractive markets and into broader geographies;
    Providing the optimal mix of client offerings, including a higher percentage of solutions; and
    Creating a stronger platform for innovation to continue to meet clients’ evolving needs.

Our confidence is shared by numerous third parties who have highlighted the opportunity to enhance growth across three key areas – health benefits exchange, large market property and casualty (“P&C”) brokerage and global health and group benefits.1

 

“…we understand that an inordinate amount of investor interest on TW has been focused on the healthcare exchange business opportunity...but the big picture is considerably more global than just that...in this case, the opportunity to build on existing leadership positions (e.g., benefits, exchange, risk) and improve the market position in areas where scale / global reach are important (e.g., broking, re-insurance).” – Citi, June 30, 2015

“...[The combined company] also broadens out TW’s reach with its global benefits solution and should enable the new company to continue to expand distribution of its exchange in the middle markets... Willis can leverage TW’s existing large company base to cross-sell.” – Bank of America Merrill Lynch, July 1, 2015

 

“The Willis merger represents a catalyst for upside in exchange revenue growth given increased penetration of the middle market channel.” – Piper Jaffray, August 11, 2015

 

“...Towers continues to believe small and middle-market sized companies will comprise the majority of new private exchange enrollees on January 1, 2017. We agree with this view and this is the primary reason why we are convinced the Willis/Towers Watson merger is an excellent strategic move by both companies. Willis has the country’s most extensive broker distribution network concentrating on small and mid-sized organizations in the country.” – MKM Partners, August 12, 2015

THE MARKET RECOGNIZES TOWERS WATSON’S TRACK RECORD OF MOE SUCCESS

The Towers Watson management team has a history of successfully integrating transactions and surpassing market expectations, including the highly successful Towers Perrin/Watson Wyatt MOE in 2010. Towers Watson’s track record is illustrated by the 140% increase in Towers Watson’s share price since the time of that merger2 and acknowledged by third-party experts:3

 

“...we can point to a prior track record in the case of the TW management, in terms of successfully executing a very large acquisition (Watson Wyatt and Towers Perrin) and materially exceeding the 3-year synergy target in just two years.” – Citi, July 1, 2015

 

“The CEO of Towers Watson, John Haley, has a very good track record of integrating large transactions and implementing cost savings initiatives.” – SunTrust Robinson, June 30, 2015

 

“TW CEO John Haley has piloted a number of transactions that were not initially appreciated by investors in the past, but proved to be smart, value-added transactions in the long run. This includes recent key transactions of the merger of equals with Towers Perrin and acquisition of Extend Health to enter the private exchange space.” – Robert W. Baird, June 30, 2015
