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 Restricted Stock Fair Value of Name Cash Bonus(1) Grant Date Units(2) Stock Awards - -------------------- ------------- ---------- ---------------- -------------- J.

March 2009


Dear [name]

I am pleased to inform you that you are scheduled to receive a bonus with a
total value of $________ (the "Total Award"). The Total Award will be
distributed to you in two portions: (a) a Willis Retention Award in the amount
of $________ (less applicable payroll deductions and taxes) to be distributed to
you subject to the terms and conditions below; and (b) restricted stock units
("RSUs") of shares of Willis Group Holdings Ltd. ("Shares") equal to the value
of the remaining portion of your Total Award based on the closing price of
Shares on the NYSE on the grant date. In addition, for every four whole RSUs
awarded, the Group will award one further RSU.

All RSUs distributed under this letter will vest in equal one-half installments
on the first and second anniversaries of grant, provided that you remain
continuously employed by Willis or one of its affiliates between the date of
grant and the given vest date, and subject to the terms and conditions of the
applicable plan. An RSU gives you the conditional right to receive one Willis
common share, on the date of vesting, for every RSU awarded.

Dividends are normally not paid until the RSUs have vested and you have received
Willis shares, provided you are the holder of the shares on the dividend record
dates. However, as an exception under this program, dividend equivalent sums
will accrue during the period from the date of grant and vesting. These dividend
equivalent sums will be paid, on the RSUs vesting, in cash less applicable
taxes.

Additional details and documentation relating to the RSU grant will be sent to
you shortly.

The Willis Retention Award portion of your Total Award will be included in your
March 2009 pay, subject to the terms and conditions below:

o    You must be employed by Willis(3) on the date that the Willis Retention
     Award would normally be distributed to be eligible to receive such payment
     and you must have signed and returned this letter as indicated below.

o    If your employment with Willis ends prior to December 31, 2011 for any
     reason other than your incapacity to work due to your permanent disability
     (as "disability" or a substantially similar term is defined within an
     applicable Willis long term disability plan/policy) or death, your
     redundancy (as redundancy is determined by Willis in accordance with its
     usual human resource administration practices) or your retirement(4), you
     will be obligated to repay to Willis a pro-rata portion of the gross amount
     of the Willis Retention Award (the "Repayment Obligation") - such Repayment
     Obligation must be promptly satisfied, as more fully explained below. The
     amount of your Repayment Obligation will be calculated by reducing the
     gross amount of the Willis Retention Award by a sum equal to 1/36th of your
     Willis Retention Award for each calendar month of employment you complete
     with Willis after January 1, 2009.

______________________
(3) As used in this letter, "Willis" refers to that Willis legal entity by which
you are employed as of the date of this letter.

(4) To the extent applicable and practicable, "retirement" will be defined by
either (i) your employment agreement (i.e., if you are subject to an employment
agreement which defines retirement or a substantially similar term) or (ii) a
written retirement policy applicable to you as a Willis employee or (iii) by
reference to the ending of your employment at age 65 or such other age as may
apply in the applicable employment jurisdiction or (iv) as may be determined by
Willis in its absolute discretion.

                                                                               7

o By signing this letter, you irrevocably authorize Willis (to the extent allowed by applicable law and at Willis's discretion and option) to withhold from any salary payments and/or other payment(s), as may be due to you from Willis at the time of and/or after your employment ends, such amount as necessary to satisfy, but not exceed, any Repayment Obligation you may have to Willis at the end of your employment. If such withholding is insufficient to satisfy such Repayment Obligation, or if Willis for any reason does not make any such withholding, you agree to pay to Willis an amount equal to your unsatisfied Repayment Obligation within 30 days of Willis's written request for such payment. o This letter shall be governed by the laws applicable to the place in which you are assigned a regular office location by Willis. If any provision of this letter is found to be invalid or unenforceable by or under any applicable law, the other provisions shall remain in full force and effect and shall not be invalidated. A breakdown of your Total Award is set out below: Total Award: $ o Amount to be paid in cash in March 2009 payroll as Willis Retention Award: $ Amount to be allocated to RSUs: $ Approximate additional RSU Match: $ o Total Award including RSU Match: $ Note that the "RSU Match" number above is an estimate only. The actual RSU match will be determined after calcuating how many RSUs could be purchased based on the closing Share price on the grant date. Please note that any dividend equivalents due from the vesting of any Bonus & Stock RSUs that you received as part of the 2007 and/or 2008 Annual Compensation Review will be paid in the end of March payroll run. Thank you for your continuing commitment to Willis and I wish you every success in the coming year. Yours sincerely FOR AND ON BEHALF OF THE COMPANY Please sign, date and return this letter (retaining a copy for your records) to Lynn Mangrum (Nashville, US Payroll) or Wendy Bannon (Ipswich, UK Payroll), as applicable, for processing in the next available payroll run.
