Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) Automatic conversion from Class B-2 to Class A shares. Balance of shares consists of an equal number of shares of Class B common stock in subclasses B-3 and B-4, which, as a result of the closing of the merger under the Agreement and Plan of Merger (the Merger Agreement) entered into between (among others) Towers, Perrin, Forster & Crosby, Inc. and Watson Wyatt Worldwide, Inc., were issued by the Issuer. Subclasses B-3 and B-4 of the Issuer's Class B common stock will automatically convert to shares of Class A common stock of the Issuer on the third and fourth anniversaries, respectively, of the effective time of the merger.
(2) Shares of restricted Class A common stock were issued by the Issuer on January 1, 2010. These shares of restricted Class A common stock vest over a three-year period, with one-third automatically vesting on each of January 1, 2011, 2012 and 2013. The transaction reflects the share amount and date such shares were deemed withheld to satisfy statutory tax withholdings due on the immediate vested portion of shares.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
