WILLIS GROUP HOLDINGS LIMITED

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

1. THE COMPANY AND ITS OPERATIONS

        Willis Group Holdings Limited ("Willis Group Holdings") and subsidiaries (collectively, the "Company") provide a broad range of value-added risk management consulting and insurance brokerage services, both directly and indirectly through its associates, to a diverse base of clients internationally. The Company provides specialized risk management advisory and other services on a global basis to clients in various industries, including the construction, aerospace, marine and energy industries. In its capacity as an advisor and insurance broker, the Company acts as an intermediary between clients and insurance carriers by advising clients on risk management requirements, helping clients determine the best means of managing risk, and negotiating and placing insurance risk with insurance carriers through the Company's global distribution network. The Company also provides other value-added services.

2. BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

        The accompanying consolidated financial statements (hereinafter referred to as the "Interim Financial Statements") have been prepared in accordance with accounting principles generally accepted in the United States of America ("US GAAP").

        The Interim Financial Statements are unaudited but include all adjustments (consisting of normal recurring adjustments) which the Company's management considers necessary for a fair presentation of the financial position as of such dates and the operating results and cash flows for those periods. Certain information and footnote disclosures normally included in financial statements prepared in accordance with US GAAP have been condensed or omitted. The results of operations for the three month period ended March 31, 2004 may not necessarily be indicative of the operating results that may be incurred for the entire fiscal year.

        The December 31, 2003 balance sheet was derived from audited financial statements but does not include all disclosures required by US GAAP. However, the Company believes that the disclosures are adequate to make the information presented not misleading. These Interim Financial Statements should be read in conjunction with the Company's consolidated balance sheets as of December 31, 2003 and 2002, and the related consolidated statements of operations, cash flows and changes in stockholders' equity for each of the three years in the period ended December 31, 2003 included in the Annual Report on Form 10-K filed with the Securities and Exchange Commission.

        Stock-based compensation—The Company accounts for its stock option and stock-based compensation plans using the intrinsic-value method prescribed in Accounting Principles Board Opinion No.25, Accounting for Stock Issued to Employees ("APB 25"). Accordingly, the Company computes compensation costs for each employee stock option granted as the amount by which the quoted market price of the Company's shares on the date of the grant exceeds the amount the employee must pay to acquire the shares.

        Had compensation expense for such plans been determined consistent with the fair value method prescribed by Statement of Financial Accounting Standard ("SFAS") No. 123, Accounting for

Stock-Based Compensation, using the Black-Scholes option-pricing model, the Company's pro forma net income and net income per share would have been:

3. DERIVATIVE FINANCIAL INSTRUMENTS

        The financial risks the Company manages through the use of financial instruments are interest rate risk and foreign currency risk. The Company's Board of Directors reviews and agrees on policies for managing each of these risks. The Company has applied SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities ("SFAS 133" ), as amended by SFAS 149, in accounting for these financial instruments.

        Interest rate contracts—The fair values of interest rate contracts are recorded in other assets and liabilities on the balance sheet. Changes in fair value of contracts that are effective cash flow hedges are recorded as a component of other comprehensive income with $nil recorded for the three month period ended March 31, 2004 (2003: gain $1 million). Amounts are reclassified from other comprehensive income into earnings when the hedged exposure affects earnings.

        For interest rate contracts not qualifying for hedge accounting the Company has recorded $nil in general and administrative expenses, representing the change in fair value for the three month period ended March 31, 2004 (2003: loss $1 million).

        Foreign currency contracts—The fair values of foreign currency contracts are recorded in other assets and liabilities, with changes in fair value of effective cash flow hedges recorded in other comprehensive income and changes in fair value of ineffective hedges recorded in general and administrative expenses. Amounts are reclassified from other comprehensive income into earnings when the hedged exposure affects earnings.

        For the three month period ended March 31, 2004, the Company has recorded a gain of $7 million in other comprehensive income relating to changes in fair value on contracts which are effective cash flow hedges (2003: loss $6 million). For contracts not qualifying for hedge accounting the Company has

6

---

recorded $nil in general and administrative expenses, representing the change in fair value for the three month period ended March 31, 2004 (2003: $nil).

4. PENSION PLANS

        The components of the net periodic benefit cost (income) of the UK and US defined benefit plans are as follows:

        The Company previously disclosed in its financial statements for the year ended December 31, 2003, that it expected to contribute $30 million and $14 million in 2004 to the UK and US defined benefit pension plans, respectively. As of March 31, 2004, $8 million and $2 million of contributions have been made to the UK and US defined benefit pension plans, respectively.

5. NET INCOME PER SHARE

        Basic and diluted net income per share is calculated by dividing net income by the average number of shares outstanding during each period. The computation of diluted net income per share reflects the potential dilution that could occur if dilutive securities and other contracts to issue shares were exercised or converted into shares or resulted in the issue of shares that then shared in the net income of the Company.

        For the three month period ended March 31, 2004, time-based and performance-based options to purchase 19.2 million and 6.2 million (2003: 19.9 million and 9.2 million) shares, respectively, and

7

---

0.5 million restricted shares (2003: 0.3 million), were outstanding. Basic and diluted net income per share are as follows:

        Options to purchase 5.2 million shares for the three month period ended March 31, 2004 were not included in the computation of the dilutive effect of stock options because the effect was antidilutive (2003: nil).

6. LONG-TERM DEBT

        Long-term debt consists of the following:

        On December 4, 2003, the Company entered into a credit agreement providing a $450 million term loan facility and a $150 million revolving credit facility. Borrowings under the term loan facility may be made until June 1, 2004. $150 million of the term loan facility matures on each of the third, fourth and fifth anniversaries of the agreement. The revolving credit facility is available until December 4, 2008.

        On February 2, 2004, the Company redeemed all the outstanding 9% senior subordinated notes at a redemption price of 104.5%. On the same day, the Company drew down $300 million of term loans under the senior credit facility.

        At March 31, 2004, there remained undrawn $150 million under the term loan facility and $150 million under the revolving credit facility.

7. COMMITMENTS AND CONTINGENCIES

        Claims, Lawsuits and Proceedings—The Company is subject to various actual and potential claims, lawsuits and proceedings relating principally to alleged errors and omissions in connection with the placement of insurance and reinsurance in the ordinary course of business. Similar to other

8

---

corporations, the Company is also subject to a variety of other claims, including those relating to the Company's employment practices. Some of those claims, lawsuits and proceedings seek damages in amounts which could, if assessed, be significant.

        Most of the claims, lawsuits and proceedings arising in the ordinary course of business are covered by professional indemnity or other appropriate insurance. In respect of self-insured deductibles, the Company has established provisions against these items which are believed to be adequate in the light of current information and legal advice, and the Company adjusts such provisions from time to time according to developments. On the basis of current information, the Company does not expect that the outcome of the claims, lawsuits and proceedings to which the Company is subject or of which it is aware, either individually or in the aggregate, will have a material adverse effect on the Company's financial condition, results of operations or liquidity.

8. SUPPLEMENTAL DISCLOSURES OF CASH FLOW INFORMATION

        Supplemental disclosures regarding cash flow information and non-cash flow investing and financing activities are as follows:

---

9. ACCUMULATED OTHER COMPREHENSIVE LOSS

        The components of comprehensive income are as follows:

        The components of accumulated other comprehensive loss are as follows:

10. SEGMENT INFORMATION

        The Company conducts its worldwide insurance brokerage activities through three operating segments: Global, North America and International. Each operating segment exhibits similar economic characteristics, provides similar products and services and distributes same through common distribution channels to a common type or class of customer. In addition, the regulatory environment in each region is similar. Consequently, for financial reporting purposes the Company has aggregated these three operating segments into one reportable segment.

11. CONDENSED CONSOLIDATING FINANCIAL INFORMATION

Item 2—Management's Discussion and Analysis of Financial Condition and Results of Operations

Executive Summary

        Revenues for the quarter ended March 31, 2004 increased by 20% compared to the corresponding period of 2003 with approximately 9% coming from net new business growth, approximately 8% from the effects of foreign exchange and approximately 3% from the net effect of acquisitions and disposals.

        Our operating margin increased to 35.2% in the first quarter of 2004, up from 33.5% in the corresponding period of 2003 on a reported basis. Excluding the impact of non-cash compensation charges for performance-based stock options and a non-recurring premium on the redemption of subordinated debt as described below, our operating margin was 35.5% in the first quarter of 2004, up from 35.0% a year ago.

        Net income per diluted share in the first quarter of 2004 was up 26% over the corresponding period of 2003 on a reported basis and 29% excluding the impact of non-cash compensation charges for performance-based stock options and a non-recurring premium on redemption of subordinated debt as described below.

        During the quarter, we invested further in our global network by acquiring 100% ownership (previously 30% owned) of Willis A/S, Denmark's largest insurance broker, and two reinsurance businesses in Denmark and Italy. In April 2004, we announced that we had received approval from the China Insurance Regulatory Commission to complete the purchase of a 50% equity stake in Shanghai Pudong Insurance Brokers Ltd.

        In February 2004, we redeemed all the $370 million outstanding of 9% senior subordinated notes and we repurchased 4,000,000 shares of our common stock at a cost of $148 million concurrently with a secondary offering of our shares. We also announced a 15% increase in our dividend to an annual rate of $0.75, effective from the April 2004 payment.

Critical accounting estimates

        The accounting estimates or assumptions that management considers to be the most important to the presentation of the Company's financial condition or operating performance were discussed in our Annual Report on Form 10-K for the year ended December 31, 2003. There were no significant additions or changes to these estimates or assumptions in the first quarter of 2004.

Revenues

        Total revenues increased by 20% to $665 million in the first quarter of 2004 from $555 million in the same period last year. Excluding the effects of foreign currency exchange rate movements of 8% and the effects of acquisitions and disposals of 3%, total revenues on an underlying basis were 9% higher in the first quarter of 2004 than in the first quarter of 2003 attributable to net new business growth. The impact from premium rates was immaterial. Premium rates continued to moderate during the quarter, with declines in some property lines and modest increases in casualty and professional liability lines.

        Global:    Revenues generated by our Global business increased by 17% to $351 million in the first quarter of 2004. Approximately 9% of the increase in revenues arose from the effects of foreign currency exchange rate movements. The effect of acquisitions and disposals accounted for a further 1%. Adjusting for these effects, revenues on an underlying basis increased by 7%. Good performances in Global Markets and Reinsurance business units contributed to this growth although there was some easing in aerospace and marine renewals. Our European reinsurance platform was enhanced with two acquisitions in Denmark and Italy early in 2004.

21

---

        North America:    Revenues generated by our North America business increased by 11% to $175 million in the first quarter of 2004 attributable to solid contributions from our middle market, large account and specialty practices (notably executive risk, employee benefits and construction) through new business development (including Fortune 1000 accounts) and recruitment.

        International:    Revenues generated by our International business increased by 45% to $139 million in the first quarter of 2004. Foreign currency exchange rate movements accounted for approximately 17% of the reported increase in revenues, and the effect of acquisitions and disposals accounted for a further 17%. Adjusting for these items, International's revenues on an underlying basis increased by 11%, led by good performance in Continental Europe and Latin America. In January 2004, we acquired the remaining 70% interest in Willis A/S, Denmark's largest insurance broker, with annualized revenues of approximately $50 million.

Expenses

        General and administrative expenses (excluding non-cash compensation for performance-based stock options) were $417 million in the first quarter of 2004, up 19% from the first quarter of 2003. Approximately 9% of the reported increase was attributable to foreign currency exchange rate movements and approximately 2% was attributable to the net effect of acquisitions and disposals. Adjusting for these items, general and administrative expenses grew by 8% in the first quarter of 2004 compared with the corresponding period of 2003. Salaries and benefits, including incentive-based compensation, amounted to 48% of revenues in the first quarter of 2004, the same proportion as in the first quarter of 2003.

        We recorded a non-cash charge for performance-based stock options of $2 million in the first quarter of 2004 compared with $8 million in the same period a year ago. As previously disclosed, this charge recognizes performance-based stock options granted to management for exceeding 2001 and 2002 performance targets. On a cumulative basis as at March 31, 2004, we had recognized $260 million, or approximately 96% of the estimated total charge. The remaining charge of approximately $12 million will be recognized quarterly in accordance with the vesting schedule through the end of 2004, when substantially all the performance options will have vested.

Operating income and operating margin

        Operating income increased by 26% to $234 million in the first quarter of 2004. Excluding the non-cash compensation charge for performance-based stock options ($2 million in the first quarter of 2004 and $8 million in the first quarter of 2003), operating income increased by 22% to $236 million in the first quarter of 2004 compared to the first quarter of 2003. We use operating income excluding non-cash compensation and gains on disposals as a measure of cash generated by the businesses.

        Operating margin, or operating income as a percentage of revenues, increased to 35.2% in the first three months of 2004 compared with 33.5% in the corresponding period of 2003. Excluding non-cash compensation, operating margin expanded to 35.5% from 35.0% in the first three months of 2004 compared with the corresponding period of 2003.

Interest expense

        Interest expense in the first quarter of 2004 was $5 million compared with $15 million in the first quarter of 2003, reflecting the significantly lower amounts of debt outstanding during the first three months of 2004 and the lower interest rates on our new credit facilities.

22

---

Income taxes

        Income tax expense for the first quarter of 2004 amounted to $72 million, an effective rate of 34%. Adjusting for that part of the non-cash performance option charge which is not tax deductible, the underlying tax rate for the first quarter of 2004 was also 34% compared with 35% in the corresponding period of 2003.

Net income

        Net income in the first quarter of 2004 increased by 26% to $148 million ($0.87 per diluted share) from $117 million ($0.69 per diluted share) in the first quarter of 2003. Net income was impacted by the non-cash charge for performance options and the non-recurring premium paid on the redemption of the subordinated debt. Excluding the non-cash charge for performance options, net of tax, of $2 million in the first quarter of 2004 and $6 million in the first quarter of 2003 and the subordinated debt redemption premium, net of tax, of $10 million in the first quarter of 2004, net income increased by 30% to $160 million from $123 million in the first quarter of 2003 and net income per diluted share rose by 29% to $0.94 from $0.73 a year ago. Acquisitions in the first quarter of 2004 added about $0.04 per diluted share and foreign exchange rate movements added about $0.03 per diluted share.

Liquidity and capital resources

        On February 2, 2004, we redeemed all the $370 million then outstanding of our 9% Senior Subordinated Notes. To finance the repayment, we drew down $300 million of bank loans under our senior credit facility with the remaining balance of $70 million and call premium of $17 million being financed using cash from operations. Also in February 2004, we repurchased and cancelled 4,000,000 shares of common stock at a cost of $148 million.

        Net cash provided by operations, which excludes fiduciary cash movements, increased to $163 million in the first quarter of 2004 from $95 million in the first quarter of 2003.

        Net cash used in investing activities amounted to $65 million in the first quarter of 2004 compared with $59 million in the first quarter of 2003. Capital expenditures for the first three months of 2004 and 2003, less the proceeds from disposals of fixed assets, were $13 million and $8 million, respectively. The increased capital expenditure in 2004 related primarily to information technology systems and continues to be managed in a disciplined manner with future information technology expenditures not being committed ahead of cash generation.

        Cash used for acquisitions in the first three months of 2004 amounted to $49 million (net of cash acquired), primarily incurred in acquiring the additional 70% interest in Willis A/S in Denmark and acquiring two reinsurance businesses in Denmark and Italy.

        Cash used in financing activities amounted to $252 million in the first quarter of 2004 compared with $58 million in the corresponding period of 2003, mainly reflecting the redemption of our subordinated debt and repurchase of our shares as described above.

        As of March 31, 2004, we had cash and cash equivalents of $211 million. We expect that internally generated funds will be sufficient to meet our foreseeable operating cash requirements, capital expenditures and dividend payments.

        Under the credit facilities negotiated in December 2003, there remains $150 million available for draw down under the term loan facility until June 2004. In addition, we have an undrawn $150 million revolving credit facility.

Contractual obligations

        Apart from the redemption of the 9% senior subordinated notes amounting to $370 million in February 2004, and the draw down of $300 million of term loans, as mentioned above, there have been no material changes in our contractual obligations since December 31, 2003.

Off-Balance Sheet Transactions

        Apart from commitments and contingencies, as disclosed in Note 7 of Notes to the Consolidated Financial Statements, the Company has no off-balance sheet arrangements that have, or are reasonably likely to have, a material effect on the Company's financial condition, results of operations or liquidity.

Subsequent Events

        Subsequent to the end of the first quarter, the Company has received a subpoena from the Office of the Attorney General of the State of New York requesting information regarding certain compensation agreements between insurance brokers and insurance companies. The New York Department of Insurance has also requested information concerning these arrangements. The Company is cooperating fully with both requests. The compensation agreements, also known as contingent agreements, are a longstanding and common practice within the insurance industry. Both investigations are at very early stages, but appear to focus on the adequacy of disclosure and potential conflicts of interest concerning such arrangements. For many years, the Company's policy has been to disclose such arrangements to clients in contracts and on our web site and believes that the remuneration it receives pursuant to these arrangements is appropriate. It is not possible at this time to predict what the ultimate outcome of these investigations will be.

Item 3—Quantitative and Qualitative Disclosures about Market Risk

        There has been no material change with respect to market risk from that described in our Annual Report on Form 10-K for the year ended December 31, 2003.

Item 4—Controls and Procedures

        Based on an evaluation of the effectiveness of the Company's disclosure controls, as of March 31, 2004, the Company's Chief Executive Officer and Chief Financial Officer concluded that the Company's disclosure controls and procedures are effective in ensuring that all material information required to be included in the Company's filings or submissions under the Securities Exchange Act of 1934 is made known to them in a timely fashion.

        There have been no significant changes in the Company's internal controls or in other factors that could significantly affect these internal controls subsequent to the date of our most recent evaluation.
