Item 5.02 Departure of Directors or Certain Officers; Election of Directors;
Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

Willis Group Holdings Limited (the "Company") has awarded annual retention
awards for 2008 to its senior executive officers (the "Willis Retention
Awards"), including its Chairman and Chief Executive Officer. The Willis
Retention Awards, which are subject to acceptance by the employee of the award's
terms and conditions, were executed by the named executive officers on March 10
and 11, 2009. Consistent with his Employment Agreement, Mr. Plumeri received 50%
of his 2008 bonus in cash and 50% in restricted stock units ("RSUs"). The Willis
Retention Awards for Messrs. Millwater, Regan and Hearn were paid approximately
82% in cash and 18% in RSUs. The RSUs were granted on March 2, 2009 at $20.97,
the closing price on the New York Stock Exchange on that date for the Company's
shares. In addition, Messrs. Plumeri, Millwater, Regan and Hearn received 1
matching RSU for every 4 granted and dividend equivalent sums will accrue from
the date of grant and will be paid in cash upon the vesting of the RSUs. The
amount of Willis Retention Awards shown below against their respective names
reflects the amount of bonus paid in cash and in RSUs, inclusive of a 1 to 4
matching award. Both the cash and RSU elements of the Willis Retention Award
paid to these executive officers are subject to forfeiture conditions if they
voluntarily leave the Company's employ: the cash element will require a
proportional reimbursement if an executive officer voluntarily leaves the
Company's employ before December 31, 2011; and the RSUs vest in equal tranches
on the first and second anniversaries of grant, subject to the executive officer
continuing to be in the Company's employ on those dates.

The following named executive officers received Willis Retention Awards as
detailed below:

                                                 Number of        Grant Date
