These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the assets available for benefits of the Plan at December 31, 2001 and 2000, and the changes in its assets available for benefits for the years then ended, in conformity with accounting principles generally accepted in the United States. Our audits were performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The accompanying supplemental schedule of assets (held at end of year) as of December 31, 2001, is presented for purposes of additional analysis and is not a required part of the financial statements, but is supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. This supplemental schedule is the responsibility of the Plan's management. The supplemental schedule has been subjected to the auditing procedures applied in our audits of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole.

5 - Employer Plan Identification # 36-3051915 Plan # 020 AON SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS Years Ended December 31, 2001 and 2000 1. DESCRIPTION OF PLAN GENERAL The Aon Savings Plan (the Plan) was authorized by the Board of Directors of Aon Corporation (the Company or Plan Sponsor). It is a defined contribution plan with a salary deferral feature and an employee stock ownership (ESOP) feature. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). Effective March 31, 2001, the ASA Savings Plan merged into the Plan and as a result, assets approximating $13.8 million were transferred into the Plan. Certain Plan assets are held by the Aon Funds, an affiliated, open-end management investment company. The assets of the ESOP portion of the Plan are invested primarily in common stock of the Company. Additionally, certain assets are invested by the Trustees as deemed advisable in order for the Plan to meet its cash flow needs. On April 20, 2001, the Company's Board of Directors approved, in principle, a plan to spin off its insurance underwriting business (which include the operations of the Company) to the Company's common stockholders, creating two independent publicly traded companies. The spin-off would take the form of a tax-free stock dividend of the outstanding shares of common stock of Combined Specialty Group, Inc., a new subsidiary of the Company formed in September, 2001 to hold its underwriting business. The transaction requires final Company Board of Director approval and certain insurance regulatory approvals, and is expected to be completed as soon as practicable. The spin-off is not expected to have a material impact on the results of operations or financial position of the Plan. The following description of the Plan provides only general information. Participants of the Plan should refer to the Summary Plan Description for a more complete description of the Plan. - 6 - 1. DESCRIPTION OF PLAN (CONTINUED) ELIGIBILITY AND PARTICIPATION Effective January 1, 2001, employees other than field sales agents or employees scheduled to work less than 20 hours per week are immediately eligible to participate. Prior to January 1, 2001, employees became eligible for participation after attaining 21 years of age and completing one year of service. Participants must complete one year of service to be eligible for company matching contributions. CONTRIBUTIONS PARTICIPANT - Participant contributions are made by means of regular payroll deductions. Non-highly compensated participants, as defined by the Internal Revenue Code (IRC), may elect to make contributions between 1% and 16% of their compensation, as defined by the Plan. Highly compensated participants, as defined by the IRC, may elect to make contributions between 1% and 8% of their compensation, as defined by the Plan. Participant contributions are limited to amounts allowed by the Internal Revenue Service (IRS). Accordingly, the maximum participant contribution was $10,500 in 2001 and 2000. COMPANY - The Company contributes an amount equal to 100% of the first 3% of a participant's compensation that a participant contributes to the Plan. The Company makes a further contribution to the ESOP portion of the Plan equal to 75% (50% for field sales agents) of the next 3% of compensation that is contributed to the Plan. In 2001 and 2000, this contribution was made in shares of common stock of the Company. The Plan requires that a participant be actively employed and contributing to the Plan as of the last day of the Plan year in order to receive a Company contribution. Contributions to the ESOP portion of the Plan are automatically invested in common stock of the Company. INVESTMENT OPTIONS Contributions to the Plan, other than for the ESOP portion, may be invested in any of the various investment alternatives offered by the Plan in any whole percentages. Additionally, beginning in 2000, a Self-Managed Account was offered whereby participants can invest their self-directed contributions in various stock and mutual funds. - 7 - 1. DESCRIPTION OF PLAN (CONTINUED) PARTICIPANT ACCOUNTS Each participant's account is credited with the participant's contribution and a) an allocation of the Company's contributions, b) an allocation of Plan earnings, and c) an allocation of forfeitures of terminated participants' non-vested accounts. The benefit to which a participant is entitled is the benefit that can be provided from the participant's account. VESTING For the ESOP portion of the Plan, a participant vests in 20% increments and becomes 100% vested after completion of five years of plan service. Forfeitures of non-vested accounts are allocated to the remaining participants. The amount of forfeitures allocated to participants was $673,000 and $1,221,000 of the Company's common stock in 2001 and 2000, respectively. For the non-ESOP portion of the Plan, participants are fully vested in their contributions plus actual earnings thereon. Participants become 100% vested in the remainder of their account balance after five years of plan service, according to a graded schedule. Forfeitures of non-vested accounts are allocated to the remaining participants. The amount of forfeitures allocated to participants was $833,000 and $947,000 for 2001 and 2000, respectively. BENEFIT PAYMENTS For the ESOP portion of the Plan, a participant's entire account shall be paid to the participant or designated beneficiary in a lump sum upon normal retirement, permanent disability or death. The participant may elect payment in the form of Company common stock or cash. For the non-ESOP portion, on termination of service, a participant may elect to receive either a lump sum amount equal to the value of his or her account and/or monthly installments over a period not to exceed ten years. PLAN TERMINATION Although it has not expressed any intent to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, participants will become 100% vested in their accounts. - 8 - 1. DESCRIPTION OF PLAN (CONTINUED) PARTICIPANT LOANS Under the loan provision of the Plan, each participant is permitted one loan in a twelve month period and the outstanding balance of all loans made to a participant may not exceed the lesser of $50,000 or 50% of the vested portion of the participant's account excluding the ESOP portion of the account. The interest rate for each loan is equal to 1% plus the prime rate as quoted in The Wall Street Journal for the last day of the month preceding the loan request. Loans are made for a period of up to five years, except for residential loans that have a fixed repayment period of ten years. 2. SIGNIFICANT ACCOUNTING POLICIES BASIS OF ACCOUNTING The financial statements of the Plan are prepared on an accrual basis in accordance with accounting principles generally accepted in the United States. INVESTMENT VALUATION AND INCOME RECOGNITION Investments are carried at fair value, which for marketable securities is based on quotations obtained from national securities exchanges and various other sources. Participant loans are valued at their outstanding balances which approximates fair value. Interest income is recorded as earned. Dividend income is recorded on the ex-dividend date. Realized gains or losses on investments are the difference between the proceeds received and the cost of investments sold as determined on a first-in, first-out basis. The change in the difference between fair value and the cost of investments is reported as unrealized appreciation or depreciation of investments. ADMINISTRATIVE EXPENSES Administrative expenses of the Plan, including expenses of the Trustees, are paid from the Plan assets, except to the extent that the Company, at its discretion, may decide to pay such expenses. The Company did not pay any Plan expenses in 2001 or 2000. There were no expenses paid to subsidiaries of the Company in 2001 or 2000. - 9 - 2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) USE OF ESTIMATES The preparation of the financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. RECLASSIFICATIONS Certain amounts in the 2000 financial statements have been reclassified to conform with the 2001 presentation. 3. INVESTMENTS Institutional Trust Company (ITC) is custodian of the Plan assets and Trustee for all Plan assets except the ESOP shares. For the ESOP shares, members of the Company's management are the trustees. The Trustees are named fiduciaries under ERISA. As used herein, Trustee refers to the ITC and Company's management individually and collectively. - 10 - 3.

INCOME TAX STATUS The Plan has received a determination letter from the IRS dated April 10, 1995, stating that the Plan is qualified under section 401(a) of the IRC and, therefore, the related trust is exempt from taxation. Subsequent to this issuance of the determination letter, the Plan was amended. Once qualified, the Plan is required to operate in conformity with the IRC to maintain its qualification. The Plan Administrative Committee believes the Plan is being operated in compliance with the applicable requirements of the IRC and, therefore, believes that the Plan, as amended, is qualified and the related trust is tax exempt. - 12 - Employer Identification # 36-3051915 Plan # 020 AON SAVINGS PLAN Schedule H, Line 4i - SCHEDULE OF ASSETS (HELD AT END OF YEAR) December 31, 2001 Number of Shares Current Value ---------------- ------------- Identity of Issuer Principal Amount (thousands) ------------------------------------------------------------------------------------------------------------------ AON COMMON STOCK FUND --------------------- COMMON STOCK Aon Corporation Common Stock, 1.00 par* 7,252,319 $ 262,108 ============== MONEY MARKET FUND ----------------- MUTUAL FUND Investments held in the Aon Money Market Fund* 264,986,899 $ 264,987 ============== GOVERNMENT SECURITIES FUND -------------------------- MUTUAL FUND Investments held in the Aon Government Securities Fund* 4,818,646 $ 49,054 ============== TOTAL RETURN FUND ----------------- MUTUAL FUND Investments held in the Aon Asset Allocation Fund* 10,128,881 $ 136,943 ============== COMMON STOCK INDEX FUND ----------------------- MUTUAL FUND Investments held in the IRT 500 Index Fund 8,484,943 $ 236,815 ============== - 13 - Employer Identification # 36-3051915 Plan # 020 AON SAVINGS PLAN Schedule H, Line 4i - SCHEDULE OF ASSETS (HELD AT END OF YEAR) December 31, 2001 (continued) Number of Shares Current Value ---------------- ------------- Identity of Issuer Principal Amount (thousands) ------------------------------------------------------------------------------------------------------------------ REAL ESTATE SECURITIES FUND --------------------------- MUTUAL FUND Investments held in the Vanguard REIT Index Fund 2,150,396 $ 26,084 ============== INVESCO DYNAMICS FUND --------------------- MUTUAL FUND Investments held in the INVESCO Dynamics Fund 1,319,748 $ 21,024 ============== IRT CORE-BALANCED FUND ---------------------- MUTUAL FUND Investments held in the IRT Core-Balanced Fund 407,942 $ 3,773 ============== DODGE & COX COMMON STOCK FUND ----------------------------- MUTUAL FUND Investments held in the Dodge & Cox Common Stock Fund 317,063 $ 31,868 ============== PIMCO TOTAL RETURN FUND ----------------------- MUTUAL FUND Investments held in the PIMCO Total Return Fund 1,399,468 $ 14,638 ============== - 14 - Employer Identification # 36-3051915 Plan # 020 AON SAVINGS PLAN Schedule H, Line 4i - SCHEDULE OF ASSETS (HELD AT END OF YEAR) December 31, 2001 (continued) Number of Shares Current Value ---------------- ------------- Principal Amount (thousands) ------------------------------------------------------------------------------------------------------------------ MONTAG & CALDWELL GROWTH FUND ----------------------------- MUTUAL FUND Investments held in the Montag & Caldwell Growth Fund 302,761 $ 7,387 ============== MANAGERS SPECIAL EQUITY FUND ---------------------------- MUTUAL FUND Investments held in the Managers Special Equity Fund 186,278 $ 13,151 ============== TEMPLETON EMERGING MARKETS FUND ------------------------------- MUTUAL FUND Investments held in the Templeton Emerging Markets Fund 115,853 $ 936 ============== VANGUARD ADMIRAL INTERMEDIATE TERM ---------------------------------- TREASURY FUND ------------- MUTUAL FUND Investments held in the Vanguard Admiral Intermediate Term Treasury Fund 1,124,290 $ 12,401 ============== IRT INTERNATIONAL EQUITY FUND ----------------------------- MUTUAL FUND Investments held in the IRT International Equity Fund 1,802,592 $ 32,212 ============== - 15 - Employer Identification # 36-3051915 Plan # 020 AON SAVINGS PLAN Schedule H, Line 4i - SCHEDULE OF ASSETS (HELD AT END OF YEAR) December 31, 2001 (continued) Number of Shares Current Value ---------------- ------------- Principal Amount (thousands) ------------------------------------------------------------------------------------------------------------------ ESOP ALLOCATED FUND -------------------- COMMON STOCK Aon Corporation Common Stock, 1.00 par* 5,642,700 $ 81,285 $ 202,435 ============= ============== OTHER COMMON AND PREFERRED STOCKS AND MUTUAL FUNDS (SELF-MANAGED FUNDS) ----------------------------------------------------------------------- COMMON STOCK ACT Manufacturing Inc.
