       Willis Group Reports Strong Second Quarter 2006 Results;
         Eight Percent Reported Revenue Growth and Ten Percent
      Organic Revenue Growth are Company's Highest in Two Years

    NEW YORK--(BUSINESS WIRE)--Aug. 2, 2006--

   Board Authorizes New $1 Billion Stock Buy Back Plan and Declares
                      Regular Quarterly Dividend

    Willis Group Holdings Limited (NYSE: WSH), the global insurance
broker, today reported results for the quarter and six months ended
June 30, 2006.
    Commenting on today's results, Joe Plumeri, Chairman and Chief
Executive Officer, said, "We have already begun successfully
implementing the Shaping Our Future initiatives throughout Willis. Our
10 percent organic revenue growth in the second quarter is a clear
demonstration of the effectiveness of our sales culture. In addition,
we see traction and accretion from the new hires that we made over the
last few years. Importantly, the expansion of our underlying margins
and profitability are direct results of solid growth and contributions
from each and every area of our business through the first half of
2006."
    "We are confident that achieving leadership in our core businesses
and delivering the best value to our clients through our distribution
network will make a significant impact on our Company and drive our
financial performance. We are focused on businesses where our unique
expertise allows us to deliver superior advice, products and services.
In addition, we believe that our extensive retail distribution
network, client advocacy and efficient delivery platform makes Willis
the broker most valued by our clients." Mr. Plumeri continued, "The
Board's authorization of a new $1 billion stock buy back plan is a
clear indicator of their confidence in the future of Willis and a
recognition that our best use of capital is to invest in ourselves."

    Second Quarter 2006 Financial Results

    Total reported revenues for the quarter ended June 30, 2006 were
$593 million, compared with $549 million for the same period last
year, an increase of 8 percent. The effect of foreign currency
translation decreased reported revenues by 1 percent and net
acquisitions of operations increased reported revenues by 1 percent.
    Organic growth in commissions and fees excluding total market
remuneration was 10 percent in the second quarter 2006. Each business
unit had a strong contribution to overall organic growth in
commissions and fees including Global with 13 percent organic growth
in the quarter (including double digit organic growth in Reinsurance),
North America with 8 percent and International with 6 percent.
    The reduction of total market remuneration as well as changes to
the quarterly phasing of incentive compensation in 2006 impacted the
year-over-year comparison of adjusted operating margin by over 4
percentage points in the second quarter of 2006 compared to the second
quarter of 2005. The reported (and adjusted) operating margin was 20.1
percent in the second quarter of 2006, and excluding these items, this
represented an over 2 percentage point improvement in adjusted
operating margin over the second quarter of 2005.
    Other expenses for the second quarter of 2006 were $108 million,
or 18.2 percent of total revenues, compared to $98 million, or 17.9
percent in the comparable period last year, relatively flat despite
incremental spending for strategic initiatives.
    Excluding the effects on taxation of amortization of intangibles,
disposals of operations and share-based compensation, the underlying
tax rate in the second quarter of 2006 was 31.5 percent, the same as
the underlying rate for the full year 2005.
    Reported and adjusted net income for the quarter ended June 30,
2006 was $72 million, or $0.45 per diluted share, compared with a
reported net income of $114 million, or $0.70 per diluted share, a
year ago and adjusted net income of $73 million, or $0.45 per diluted
share, for the same period last year. Foreign currency translation had
no impact on second quarter 2006 net income compared with second
quarter 2005.

    Six Months 2006 Financial Results

    Total reported revenues increased by 4 percent to $1,264 million
in the first six months of 2006, up from $1,218 million for the
corresponding period in 2005. The effect of foreign currency
translation decreased reported revenues by 2 percent and net disposals
of operations decreased reported revenues by 1 percent.
    The reduction of total market remuneration as well as changes to
the quarterly phasing of incentive compensation in 2006 impacted the
year-over-year comparison of adjusted operating margin by over 1
percentage point in the first half of 2006 compared to the first half
of 2005. The reported (and adjusted) operating margin was 25.6 percent
in the first half of 2006, and excluding these items, this represented
an over 1 percentage point improvement in adjusted operating margin
over the first half of 2005.
    Other expenses for the first half of 2006 were $213 million, or
16.9 percent of total revenues, compared to $194 million, or 15.9
percent in the comparable period last year (excluding the first
quarter 2005 non-operating items), principally as a result of
incremental spending for strategic initiatives.
    Reported and adjusted net income for the six months ended June 30,
2006 was $212 million or $1.33 per diluted share, compared to a
reported net income of $181 million, or $1.10 per diluted share and
adjusted net income of $209 million, or $1.27 per diluted share, for
the same period last year. Foreign currency translation had a negative
$0.03 impact on results for the first six months of 2006, compared
with same period last year.

    Outlook

    For the full year 2006, the Company anticipates continued growth
in organic commissions and fees. The Company still expects salaries
and benefits expense as a percentage of total revenues to be less than
59 percent and continues to expect modest adjusted operating margin
expansion.
    In the third quarter 2006, Willis expects to incur certain
one-time expenses related to the Company's strategic initiatives.
Willis also expects to close on the sale of Ten Trinity Square, its
current London headquarters during the third quarter of 2006. The
Company is on schedule to move into a new London headquarters in late
2007/early 2008.
    The Company expects to deliver breakout financial performance in
the next five years. Specifically, by 2010, the Company has set
financial targets of salaries and benefits expense as a percentage of
total revenues to be below 54 percent, adjusted operating margin of 28
percent or better and industry leading organic revenue growth.
    In conclusion, Mr. Plumeri added, "We remain focused and committed
to the Shaping Our Future initiatives which are designed to drive
revenue and profitable growth in our Company. We have seen early signs
that the execution of our strategy is working well and expect an even
more significantly positive impact on our results in 2007 and beyond."

    Capital Management

    The Board of Directors approved a new $1 billion stock buy back
plan. This authorization replaces the Company's previously announced
$500 million buy back plan and its remaining $140 million
authorization. The buy back is an open-ended plan to purchase, from
time to time in the open market or through negotiated trades with
persons who are not affiliates of the Company, shares of the Company's
common stock.
    Separately, the Board of Directors declared a regular quarterly
cash dividend on the Company's common stock of $0.235 per share, an
annual rate of $0.94 per share. The dividend is payable on October 13,
2006 to shareholders of record on September 30, 2006.
    During the six months ended June 30, 2006 the Company completed 4
acquisitions with annual revenues of approximately $13 million. Cash
and cash equivalents totaled $210 million, including approximately
$104 million of immediately available cash at June 30, 2006. No shares
were repurchased during the first half of 2006.
    At June 30, 2006, total long-term debt was $600 million and total
stockholders' equity was approximately $1.4 billion. The
capitalization ratio (total long-term debt to total long-term debt and
stockholders' equity) was 29 percent at June 30, 2006.

                  SUPPLEMENTAL FINANCIAL INFORMATION
                       (in millions) (unaudited)

    1. Definitions of Non-GAAP Financial Measures

    We believe that investors' understanding of the Company's
performance is enhanced by our disclosure of the following non-GAAP
financial measures. Our method of calculating these measures may
differ from those used by other companies and therefore comparability
may be limited.

    Organic revenue growth

    Organic revenue growth excludes the impact of foreign currency
translation, acquisitions and disposals and total market remuneration
from reported revenues. We use organic revenue growth as a measure of
business growth generated by operations that were part of the Company
at the end of the period.

    Adjusted operating income and adjusted net income

    Our results for the six months June 30, 2005 were significantly
impacted by gains on disposal of operations, charges for regulatory
settlements and related expenses, our first quarter 2005 headcount
reduction program and other provisions. We believe that excluding
these items from operating income and net income as applicable, along
with the GAAP measures, provides a more complete and consistent
comparative analysis of our results of operations. These items did not
have a material effect on the results for the six months ended June
30, 2006.

    2. Accounting and reporting changes

    We made a number of changes to our accounting and reporting in
first quarter 2006. In particular:

    Revenue analysis

    Following a change to our internal reporting structure, North
America Global Markets and International Global Markets revenues,
which were previously reported within our Global division, are now
reported in the North America and International divisions,
respectively. In addition, we refined our method of allocating
revenues between the Global and North America divisions. We have
adjusted our 2005 revenue analysis to be consistent with the new
internal reporting structure.

    FAS 123R, Share-Based Payment

    Effective January 1, 2006, we adopted FAS 123R using the
modified-retrospective transition method. Our 2005 comparative data
has therefore been adjusted to recognize the compensation cost
previously reported in the footnote disclosure to our financial
statements.
    The retrospective application of FAS 123R has also impacted the
diluted share count in prior periods as proceeds under the treasury
stock method have been adjusted with a consequent impact on diluted
share count. Proceeds were adjusted to include the future potential
tax consequences that will arise when the options are exercised and
the average unrecognized compensation cost outstanding during the
period.

    Pensions: market-related value

    FAS 87, Employers' Accounting for Pensions, requires the expected
return on plan assets to be determined based on the expected long-term
rate of return on plan assets and the market-related value of plan
assets. The market-related value of plan assets may either be a fair
value or a calculated value that recognizes changes in a systematic
and rational manner over not more than five years.
    Up to December 31, 2005, the market-related value of our UK
pension plan assets was determined using a calculated value that
recognized asset gains or losses over five years. With effect from
January 1, 2006, the market-related value of UK pension plan assets
has been determined on a fair value basis. We believe that fair value
is a preferable measure of determining the market-related value of
plan assets as it more fairly reflects the actual value of pension
plan assets as of the balance sheet date. In addition, it brings the
methodology used for calculating the market-related value of our UK
plan assets into line with the fair value methodology already used to
value our US plan assets.
    We have adjusted our 2005 comparative data to reflect the change
in method of determining the market-related value of plan assets.

    Pensions: return on assets

    After reviewing the long-term rate of return on our UK plan
assets, effective January 1, 2006, we have increased the expected
long-term rate to 7.75% from 7.25%.

    3. Revenue analysis

    Organic revenue growth

    Organic revenue growth is defined as revenue growth excluding the
impact of foreign currency translation, acquisitions and disposals and
total market remuneration. The percentage change in reported revenues
is the most directly comparable GAAP measure, and the following table
