Report of Independent Auditors
The Participants and Administrative Committee
Aon Savings Plan
We have audited the accompanying statements of net assets available for benefits
of Aon Savings Plan as of December 31, 1998 and 1997, and the related statements
of changes in net assets available for benefits for the years then ended. 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 generally accepted auditing
standards. 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 net assets available for benefits of the Plan at
December 31, 1998 and 1997, and the changes in its net assets available for
benefits for the years then ended, in conformity with generally accepted
accounting principles.
Our audits were performed for the purpose of forming an opinion on the basic
financial statements taken as a whole. The accompanying supplemental schedules
of assets held for investment purposes as of December 31, 1998, and reportable
transactions for the year then ended, are presented for purposes of additional
analysis and are not a required part of the financial statements, but are
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. These supplemental schedules are the responsibility of the
Plan's management. The Fund Information in the statements of net assets
available for benefits and the statements of changes in net assets available for
benefits is presented for purposes of additional analysis rather than to present
the net assets available for benefits and changes in net assets available for
benefits of each fund. The supplemental schedules and Fund Information have been
subjected to the auditing procedures applied in our audits of the basic
financial statements and, in our opinion, are fairly stated in all material
respects in relation to the basic financial statements taken as a whole.

AON SAVINGS PLAN
NOTES TO FINANCIAL STATEMENTS
Years Ended December 31, 1998 and 1997
1. DESCRIPTION OF PLAN
A. GENERAL
The Aon Savings Plan (the Plan) was authorized by the Board of Directors
of Aon Corporation (the Company or Plan Sponsor). The Plan is subject to
the provisions of the Employee Retirement Income Security Act of 1974
(ERISA).
Effective January 15, 1997, Aon Corporation acquired Alexander and
Alexander Services, Inc., the plan sponsor of the Thrift Plan for
Employees of Alexander and Alexander Services, Inc. and Subsidiaries.
On January 1, 1998, the Thrift Plan for Employees of Alexander and
Alexander Services, Inc. and Subsidiaries was merged into the Plan.
Also on January 1, 1998, the Aon Employees Stock Ownership Plan (ESOP) was
merged into the Plan. The ESOP was a non-contributory, defined
contribution plan covering all employees of the Company except for
employees covered by a collective bargaining agreement. Features of the
ESOP carried over to 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. The acquisition of the Company
common stock for the ESOP was financed by loans obtained from various
lenders.
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.

1. DESCRIPTION OF PLAN (CONTINUED)
B. ELIGIBILITY AND PARTICIPATION
Participation is limited to employees who have completed one year of
service, attained the age of 21 and worked 1,000 or more hours in a
caledar year or employees who were eligible under another plan that was
merged into the Aon Savings Plan. An employee must be employed in the
United States on a permanent basis in order to participate.
C. CONTRIBUTIONS
PARTICIPANT - Participant contributions are made by means of regular
payroll deductions. Non-highly compensated Participants, as defined by the
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 IRS. Accordingly, the maximum
Participant contribution was $10,000 in 1998 and $9,500 in 1997.
COMPANY - The Company will contribute an amount equal to 100% of the first
3% of a Participant's compensation that a Participant chooses to
contribute to the Plan. The Company will make a further contribution to
the ESOP portion of the Plan equal to 75% of the next 3% of compensation
that is contributed to the Plan However, if the Company contributions
defined above (with certain restrictions) plus the dividends and
investment gains on the assets of the ESOP portion of the Plan are
insufficient to pay the interest and principal payments on the notes
payable, the Company may make additional contributions as necessary to
fully fund these payments when they become due. 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.
D. ALLOCATION OF ESOP SHARES TO PARTICIPANTS
The common stock of the Company allocated to Participants as a result of
debt service paid by allocated share dividend monies is based on account
balance. The common stock of the Company allocated to Participants as a
result of debt service paid by Participants' cash balances is based on
cash balance. The common stock of the Company allocated to Participants as
a result of all other debt service is based on eligible compensation. A
Participant's eligible compensation is limited to amounts allowed under
the Tax Reform Act of 1986. Accordingly, the maximum Participants'
eligible compensation was $160,000 for 1998 and 1997.

--------------------------
Aon International Equity Fund of the Aon Funds. The portfolio
invests primarily in equity and equity-related securities of
companies that are organized outside of the United States or whose

F. 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
Participants account.
G. 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
35,293 and 31,696 shares of the Company's common stock in 1998 and 1997,
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 $821,000 and $823,000 for 1998
and 1997, respectively.
H. BENEFIT PAYMENTS

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.

right under the Plan to discontinue its contributions at any time and
to terminate the

<PAGE>
1. DESCRIPTION OF PLAN (CONTINUED)
Plan subject to the provisions of ERISA. In the event of Plan termination,
Participants will become 100% vested in their accounts.
J. 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 which always have a repayment period
of ten years.
2. SIGNIFICANT ACCOUNTING POLICIES
A. BASIS OF ACCOUNTING
The financial statements of the Plan are prepared on an accrual basis in
accordance with generally accepted accounting principles.
B. INVESTMENT VALUATION
Investments, except for unallocated guaranteed insurance contracts, are
carried at fair value, which for marketable securities is based on
quotations obtained from national securities exchanges and various other
sources. Investments in unallocated guaranteed insurance contracts are
valued at contract value, which represents contributions made under the
contract, plus interest at the contract rate, less any withdrawals and
administrative expenses. Participant loans are valued at cost 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.
C. ADMINISTRATIVE EXPENSES
Administrative expenses of the Plan, including expenses of the Trustees,
are allocated from the Plan assets, except to the extent that the Company,
at its discretion, may decide to pay such expenses. Administrative
expenses include $1,444,000 and $860,000 in 1998 and 1997, respectively,
paid to subsidiaries of the Company.

<PAGE>
2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
D. USE OF ESTIMATES
The preparation of the financial statements in conformity with generally
accepted accounting principles 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.
3. ALLOCATION OF ESOP SHARES TO PARTICIPANTS
All ESOP shares are held by the Plan in a suspense account and are
allocated to the Participants on an annual basis as interest and principal
payments are made. The common stock allocated each year will equal the
number of unallocated shares immediately before such allocation multiplied
by the ratio of interest and principal paid on the notes during the
current Plan year to the sum of the current year payments plus principal
and interest to be paid in future years. The number of shares allocated to
Participant accounts was 733,941 and 709,143 for 1998 and 1997,
respectively.
Estimates are used to determine the amount of shares to allocate to the
Participants. These estimates are based on preliminary figures provided by
the Company and are continually reviewed and adjusted in order for the
Plan to maintain its IRS qualification. Because the allocation to
Participants is based on estimates, the ultimate allocation may vary from
the estimate. The variances are not material and are adjusted in the
following year.
4. INVESTMENTS
The Northern Trust Company is the custodian of the Plan assets and Trustee
for the Aon Stock Fund. The remaining Trustees for the Plan are members of
the Company's Investment Department, and they have been given the
discretion and authority to manage the investments. The Trustees are named
fiduciaries under ERISA.

6. NOTES PAYABLE
The Plan originally borrowed $90,000,000 from various financial
institutions to purchase 5,383,326 shares of the Company's common stock.
The notes are unconditionally guaranteed by the Company. Pursuant to the
ESOP note agreement, there is a provision for an interest rate adjustment
in the event there is a change in the Federal Tax Rate. During 1998 and
1997, the interest rate on the notes was 8.35%. The notes were segregated
into two series, Series A and Series B. During 1998 and 1997, interest
paid was approximately $2,384,000 and $3,533,000, respectively.
The Series A note allowed the Plan to borrow up to $43,900,000. Final
payment was made on June 15, 1996.
- 15 -
<PAGE>
6. NOTES PAYABLE (CONTINUED)
The Series B note allowed the Plan to borrow up to $46,100,000. Principal
payments are scheduled to be repaid annually beginning September 15, 1997.
Principal repayments during 1998 were $15,600,000. Interest is paid
semi-annually. At December 31, 1998, the Series B note balance was
$17,500,000. The final principal payment of $17,500,000 is due to be paid
on June 15, 1999.
7. FEDERAL INCOME TAXES
The IRS ruled on April 10, 1995 that the Plan qualified under Section
401(a) and (k) of the IRC and therefore, the related trust is not subject
to tax under present income tax law. 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 qualified under the
relevant sections of the Code and is not aware of any course of action or
series of events that have occurred that might adversely affect the Plan's
qualified status.
8. YEAR 2000 ISSUE (UNAUDITED)
The Plan Sponsor has determined that it will be necessary to take certain
steps in order to ensure that the Plan's information systems are prepared
to handle year 2000 dates. The Plan Sponsor is taking a two phase
approach. The first phase addresses internal systems that must be modified
or replaced to function properly. Both internal and external resources are
being utilized to replace or modify existing software applications, and
test the software and equipment for the year 2000 modifications. The Plan
Sponsor anticipates substantially completing this phase of the project by
fall of 1999. Cost associated with modifying software and equipment are
not estimated to be significant and will be paid by the Plan Sponsor.
For the second phase of the project, Plan management established formal
communications with its third party service providers to determine that
they have developed plans to address their own year 2000 problems as they
relate to the Plan's operations. All third party service providers have
indicated that they will be year 2000 compliant by late 1999. If
modification of data processing systems of either the Plan, Plan Sponsor,
or its service providers is not completed timely, the year 2000 problem
could have a material impact on the operations of the Plan. Plan
management has not developed a contingency plan, because they are
confident that all systems will be year 2000 ready.
9. SUBSEQUENT EVENT
Effective August 1, 1999, INVESCO was appointed custodian and record
keeper of the Plan.
