Grant of Options and RSUs

     On May 5, 2009,  Willis  Group  Holdings  Limited (the  "Company")  awarded
grants of options and  restricted  stock  units  (RSUs) to certain of its senior
executive officers.  The RSUs are being granted as part of a broader strategy to
retain  key  management  and  employees  given the  limited  retentive  value of
previously  issued  options,  while the options were part of the regular  annual
grants issued to senior  executives and employees.  The exercise price for these
option grants was at the closing price of the shares as reported by the New York
Stock Exchange on that date ($26.17 per share).  The RSUs were awarded  pursuant
to the Willis Group  Holdings  Limited 2008 Share  Purchase and Option Plan (the
"2008  Plan") and the options were  granted  pursuant to Willis  Group  Holdings
Limited 2001 Share  Purchase and Option Plan (the "2001  Plan").  The  following
named executive officers received grants of options and RSUs as detailed below:



                                                                                
Name                    Position                                   Options Granted  RSUs Granted
- ----                    --------                                   ---------------  ------------

Joseph J. Plumeri       Chairman and Chief Executive Officer              0           200,000

Patrick C. Regan        Group Chief Financial Officer and              125,000         60,000
                        Chief Operating Officer

Grahame J. Millwater    Group President and Chairman, Willis Re        150,000         80,000

Peter Hearn             Chief Executive Officer, Willis Re             100,000         40,000


     Subject to the executive  being in the  employment of the Company or any of
its  subsidiaries  on the date when the  financial  results  for the year  ended
December 31, 2009 are  published by the New York Stock  Exchange,  these options
and RSUs will be deemed earned if the Company achieves certain financial targets
for 2009 based on Adjusted  Earnings  Per Share and  Adjusted  Operating  Margin
targets. In the case of the options, 50 percent of the options will be earned if
the Company achieves  certain Adjusted  Earnings Per Share target and 50 percent
is earned upon the  achievement of certain  Adjusted  Operating  Margin targets.
RSUs will only be earned if both the Adjusted  Earnings Per Share target and the
Adjusted Operating Margin targets are achieved. As provided in the 2001 Plan and
the 2008 Plan, in  determining  whether these  targets have been  achieved,  the
Compensation  Committee may make  adjustments to take into account,  among other
things, extraordinary transactions and mergers.

     Assuming  the  executive  is employed by the Company on each of the vesting
dates,  RSUs that have been earned by virtue of achieving the financial  targets
noted above will vest as to 33% on the first  anniversary  of the date of grant,
33% on the  second  anniversary  of the  date  of  grant  and  34% on the  third
anniversary  of the date of grant.  The  shares  relating  to  vested  RSUs will
generally be deliverable to the executive within 30 days after the vesting date.
Shares  delivered  to the  executive  that relate to RSUs that vest on the first
anniversary of the date of grant (the first 33% of the RSU grant), less a number
of shares that may be required to satisfy  tax  withholding  obligations  of the
executive,  must be  held by the  executive  and may not be sold  for 12  months
following the applicable  vesting date. The shares  representing  Mr.  Plumeri's
vested RSUs shall not be deliverable,  however, until 30 days following the date
of his  separation  of service  from the  Company  and any of its  subsidiaries.
Subject to the  employee  being in the  employment  of the Company or any of its
subsidiaries at each respective date, options that have been earned by virtue of
the  achievement of the applicable  financial  targets noted above will vest 25%
per year beginning on the second anniversary of the grant.  Subject to continued
employment,   vested  options  are  generally   exercisable   until  the  eighth
anniversary of the grant.

     In  consideration  for the grant of these  options and RSUs,  the executive
must execute an Option  Agreement and a Restricted  Stock Units Award Agreement,
which  sets  forth  the terms  and  conditions  of the  option  and RSU  grants,
respectively.
