WILLIS GROUP REPORTS SECOND QUARTER 2008 RESULTS; CONTINUED EXECUTION OF SHAPING OUR FUTURE STRATEGIES FOR PROFITABLE GROWTH DRIVES RESULTS

7 Percent Growth in Reported Commissions and Fees; Strong 3 Percent Organic Growth in Commissions and Fees despite Soft Insurance Market

Reported Earnings per Diluted Share $0.27; Adjusted Earnings per Diluted Share increased 9 Percent to $0.59

Willis Group Holdings Limited (NYSE: WSH), the global insurance broker, today reported results for the quarter and six months ended June 30, 2008.

“Our three percent organic commissions and fees growth is a testament to our successful top line growth strategies and diversified business mix, despite continued softness in the insurance marketplace,” said Joe Plumeri, Chairman and Chief Executive Officer.

“We continue to diligently execute Shaping our Future strategies for profitable growth with the key Shaping our Future Marketing and Client Profitability initiatives gaining momentum,” continued Plumeri. “We are recognizing identified cost savings and remain vigilant on expense management while continuing to make investments for future growth.”

Second Quarter 2008 Financial Results

Reported net income for the quarter ended June 30, 2008 was $39 million, or $0.27 per diluted share, compared with $78 million, or $0.54 per diluted share, a year ago. The results for the second quarter 2008 were significantly impacted by pre-tax charges totaling $62 million for contract buyouts, severance and other costs.

Excluding these charges, which are reviewed in detail later in this release, adjusted earnings per diluted share increased 9 percent to $0.59 in the second quarter 2008 from $0.54 a year ago. The impact of foreign currency translation increased second quarter 2008 earnings per diluted share by $0.01 compared with the second quarter 2007.

Total reported revenues for the quarter ended June 30, 2008 were $661 million compared with $626 million for the same period last year, an increase of 6 percent. The effect of foreign currency translation increased reported revenues by 4 percent.

Organic growth in commissions and fees was 3 percent in the second quarter 2008 compared with second quarter 2007. This reflected net new business won of 5 percent; there was a negative 2 percent impact from declining premium rates tempered by other market factors, such as higher commission rates, higher insured values and changes in limits and exposures. Improved client retention levels and momentum from Shaping our Future growth initiatives, such as Shaping our Future Marketing and Client Profitability, also contributed to organic growth.

The International business segment contributed 10 percent organic growth in commissions and fees in the second quarter 2008 compared with the same period in 2007. There was continued strength in Europe, especially Spain, Denmark and Norway, and in Latin America, as well as our emerging market countries including Russia and China.

The North America segment reported organic growth in commissions and fees of negative 1 percent compared with second quarter 2007 in a soft insurance market. The North America segment continues to make strategic investments in targeted practice areas and geographies.

The Global segment, which comprises Global Specialties and Reinsurance, recorded flat organic growth in commissions and fees in the second quarter 2008 compared with second quarter 2007. Global Specialties had positive organic growth in commissions and fees across many specialty businesses. Reinsurance reported negative organic growth in commissions and fees due to declining rates across most areas and higher retention levels by the primary carriers.

Reported operating margin was 11.6 percent for the quarter ended June 30, 2008 compared with 22.0 percent for the same period last year. Excluding the charges, adjusted operating margin was 21.0 percent for the quarter ended June 30, 2008 compared with 22.0 percent a year ago, as we continue to reinvest growth in strategic hires and key initiatives. Foreign exchange translation had a negative 40 basis point impact on the adjusted operating margin.

Six Months 2008 Financial Results

Reported net income for the six months ended June 30, 2008 was $205 million, or $1.43 per diluted share, compared with $247 million or $1.65 a year ago. The results for the first six months of 2008 were significantly impacted by pre-tax charges totaling $95 million for contract buyouts, severance and other costs.

Excluding these charges, which are reviewed in detail later in this release, adjusted earnings per diluted share increased 16 percent to $1.91 in the six months ended June 30, 2008, up from $1.65 a year ago. The impact of foreign currency translation increased earnings per diluted share for the first six months of 2008 by $0.09 compared with the first six months of 2007.

Total reported revenues for the six months ended June 30, 2008 were $1,456 million compared with $1,365 million for the same period last year, an increase of 7 percent. The effect of foreign currency translation increased reported revenues by 5 percent.

Organic growth in commissions and fees was 3 percent for the six months ended June 30, 2008 compared with the same period in 2007. This growth was attributed to net new business won of 4 percent; there was a negative 1 percent impact from declining premium rates tempered by other market factors such as higher commission rates, higher insured values and changes in limits and exposures.

Reported operating margin was 20.7 percent for the six months ended June 30, 2008 compared to 27.5 percent for the same period last year. Excluding the impact of the charges relating to severance and other costs, adjusted operating margin was 27.3 percent for the six months ended June 2008, relatively flat compared with the same period last year.

The effective underlying tax rate for the six months ended June 30, 2008 was 28.0 percent, excluding the tax effects of the disposal of the London headquarters and share-based compensation. The effective underlying tax rate for full year 2008 is currently estimated to remain at approximately 28.0 percent compared to 29.5 percent in full year 2007.

Capital

The Board of Directors declared a regular quarterly cash dividend on the Company’s common stock of $0.26 per share, an annual rate of $1.04 per share. The dividend is payable on October 13, 2008 to shareholders of record on September 30, 2008.

As at June 30, 2008, cash and cash equivalents totaled $205 million, total debt was $1.5 billion and total stockholders’ equity was $1.4 billion. There were no share repurchases during the quarter and $75 million has been repurchased to date under the existing $1 billion buyback authorization.

Announcement of Hilb Rogal & Hobbs Company Acquisition

On June 8, 2008, the Company announced the acquisition of Hilb Rogal & Hobbs Company (HRH), the eighth largest insurance and risk management intermediary in the United States.

Under the terms of the definitive agreement, the Company will acquire all of the outstanding shares of common stock of HRH for $46.00 per share (subject to adjustment based on changes in the Company’s stock price in the period prior to the closing of the acquisition), with approximately fifty percent of the total consideration being paid in cash and the other fifty percent being paid in stock. The total purchase price of approximately $2.1 billion includes the assumption of approximately $400 million of HRH existing debt. Over time, the Company plans to repurchase the majority of the shares issued in connection with the merger under its existing buyback authorization.

The transaction is expected to close in the fourth quarter of 2008, subject to customary closing conditions, including regulatory and HRH shareholder approval.

Outlook

The Shaping our Future strategy is a series of initiatives designed to deliver profitable growth, and as previously reported, the Company has decided to invest in further key hires and initiatives in 2008 and 2009. As previously announced, the Company is conducting a thorough review of all businesses to identify additional opportunities to rationalize its expense base to help fund a portion of these anticipated investments. The Company incurred a pre-tax charge of $62 million in the second quarter and $95 million through the six months ended June 30, 2008 in connection with this expense review for contract buyouts, severance and other costs, including property and systems rationalizations.

The Company currently anticipates that these charges and other actions arising from the expense review will lead to cost savings in the range of $25 million to $35 million in 2008, rising to approximately $45 million to $55 million in 2009. These savings are in addition to the anticipated annualized net benefit from the 2006 Shaping our Future charges currently estimated to be approximately $30 million in 2008 and $45 million by 2009.

Excluding these charges, the Company continues to expect an adjusted operating margin of approximately 24 percent in 2008, as underlying business growth and cost savings are reinvested for future growth. The Company issued revised financial goals in conjunction with the HRH acquisition announcement, and currently expects adjusted operating margin of approximately 24 percent in 2009 and 27 percent in 2010. The Company currently expects to deliver adjusted earnings per diluted share in the range of $2.85-$2.95 in 2008, $3.15-$3.25 in 2009, and $4.05-$4.15 in 2010. Company guidance is based on the assumption that the acquisition of HRH closes on December 31, 2008.

“Overall, we’re very pleased with our first-half performance. We said we were going to deliver industry-leading organic revenue growth and a steady adjusted operating margin this year. Thus far, we’ve done that, despite soft market conditions, thanks to the great progress we’re making with our Shaping our Future initiatives,” Plumeri said. “We’re building a solid platform for future profitable growth at Willis, both with the Shaping our Future strategy and with our pending acquisition of Hilb Rogal & Hobbs, which will double the size and footprint of our North America business.”

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 commissions and fees growth

Organic commissions and fees growth excludes the impact of foreign currency translation and acquisitions and disposals from reported commissions and fees. We use organic commissions and fees 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 have been impacted by the charge related to the 2008 expense review. 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.

2. Analysis of Commissions and Fees

Organic growth in commissions and fees is defined as growth in commissions and fees excluding the impact of foreign currency translation and acquisitions and disposals. The percentage change in reported commissions and fees is the most directly comparable GAAP measure, and the following tables reconcile this change to organic growth in commissions and fees by business unit for the three and six months ended June 30, 2008:

a) With effect from January 1, 2008, gains on the disposal of intangible assets, which were previously reported within ‘Commissions and fees’ are now reported separately as ‘Other income’. As a result of this change, $3 million previously reported within North America’s commissions and fees in second quarter 2007 is now reported within other income. There was no impact on organic commissions and fees growth as originally reported for the quarter ended June 30, 2007.

b) With effect from January 1, 2008, gains on the disposal of intangible assets, which were previously reported within ‘Commissions and fees’ are now reported separately as ‘Other income’. As a result of this change, $7 million previously reported within North America’s commissions and fees in first half 2007 is now reported within other income. There was no impact on organic commissions and fees growth as originally reported for the six months ended June 30, 2007.

3. 2008 Expense Review

The Company is conducting a thorough review of all businesses to identify additional opportunities to rationalize its expense base. Consequently, the Company incurred a pre-tax charge of $62 million ($45 million or $0.32 per diluted share after tax) in second quarter 2008 for contract buyouts, severance and other costs as analyzed in the following table:

a) Severance costs relate to approximately 200 positions in the second quarter 2008 and approximately 350 positions through the six months ended June 30, 2008, which have been, or are in the process of being, eliminated.

b) Other salaries and benefits costs relate primarily to contract buyouts.

The Company currently anticipates that these charges and other actions arising from the expense review will lead to cost savings of approximately $25 million to $35 million in 2008, rising to $45 to $55 million in 2009.

4. Adjusted Operating Income

Adjusted operating income is defined as operating income excluding net gains/losses on disposal of operations and the charges related to the 2008 expense review. Operating income is the most directly comparable GAAP measure, and the following tables reconcile adjusted operating income to operating income for the three and six months ended June 30, 2008 and 2007:
