                          Independent Auditors' Report



To the Trustees and Participants
AMCORE Financial Security Plan:


We have audited the accompanying statements of net assets available for benefits
of the AMCORE Financial Security Plan (the Plan) as of December 31, 2001 and
2000, 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 trustees. 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 of America. 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 that 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 as of
December 31, 2001 and 2000, and the changes in net assets available for benefits
for the years then ended in conformity with accounting principles generally
accepted in the United States of America.

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 for investment purposes as of December 31, 2001 is presented for the
purpose of additional analysis and is not a required part of the basic financial
statements, but it 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 trustees. The supplemental schedule has been
subjected to the auditing procedures applied in the 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.

                         AMCORE FINANCIAL SECURITY PLAN

                          Notes to Financial Statements

                           December 31, 2001 and 2000


(1)    Significant Accounting Policies

              Financial Statement Presentation

              Since the AMCORE Financial Security Plan (the Plan) is subject to
              the Employee Retirement Income Security Act of 1974 (ERISA), the
              Plan prepared its financial statements and schedule in accordance
              with the financial reporting requirements of ERISA rather than in
              accordance with Regulation S-X.

              Valuation of Investments

              If available, quoted market prices are used to value investments.
              The mutual funds are valued at quoted net asset values.
              Participants' notes are valued at face value which approximates
              market. Investment in AMCORE Stable Asset Fund is valued at net
              asset value which is determined based on the fair value of the
              underlying investments. AMCORE Common Stock is valued at the last
              reported sales price on the day of valuation.

              Security transactions are accounted for on a trade-date basis.
              Dividend income is recorded on the ex-dividend date. Interest
              income is accounted for on the accrual basis.

              Payment of Benefits

              Benefits are recorded when paid.

              Accounting Estimates

              The preparation of financial statements in conformity with
              accounting principles generally accepted in the United States of
              America requires the plan trustees to make estimates and
              assumptions that affect the amounts reported in the financial
              statements and the accompanying notes. Actual results could differ
              from those estimates.

              New Accounting Pronouncement

              The Plan adopted Statement of Financial Accounting Standards
              (SFAS) No. 133, Accounting for Derivative Instruments and Hedging
              Activities, as amended by SFAS No. 138, on January 1, 2001. This
              Statement outlines accounting and reporting standards for
              derivative instruments and hedging activities. The effect of
              adoption of SFAS No. 133 on the Plan's 2001 financial statements
              is immaterial.

(2)    Plan Description

       The following description of the Plan provides only general information.
       Participants should refer to the plan agreement for a more complete
       description of the Plan's provisions.

              General

              The Plan is a defined contribution plan covering substantially all
              employees of AMCORE Financial, Inc. (AFI) and participating
              subsidiaries, who have completed ninety days of service and have
              reached the age of 18. It is subject to the provisions of ERISA.

                                       4
                                                                     (Continued)


                         AMCORE FINANCIAL SECURITY PLAN

                          Notes to Financial Statements

                           December 31, 2001 and 2000

              Contributions

              Participants may contribute up to 10%, not to exceed $10,500 of
              their annual wages on a pretax basis in 2001 and $10,000 in 2000.
              The first 3% of the employee's contribution is matched by the
              employer, dollar for dollar, and the next 2% is matched at 50%.
              Employer contributions are used to purchase AFI common stock.

              The employer contributes 3% of the participants' annual wages each
              year to a basic retirement account; these funds are set aside for
              retirement and, therefore, are not available for participant
              loans. These funds are invested in the same manner as the
              participant's contributions.

              Participant Accounts

              Each participant's account is credited with the participant's
              contributions and an allocation of the employer's contribution and
              plan earnings. Allocations are based on participant earnings, as
              defined. The benefit to which a participant is entitled is the
              benefit that can be provided from the participant's vested
              account. The Plan provides for a maximum contribution to a
              participant's account in any plan year of the lesser of $35,000 or
              25% of the participant's compensation.

              Payment of Benefits

              On termination of service, a participant may select one of several
              payment options. Withdrawals by a participant are fully taxable,
              except for the return of after tax contributions, if any.

              Vesting

              Participants are immediately vested in both their contributions
              and that of the employer.

              Investment Funds

              The assets of the Plan are segregated and maintained in fourteen
              separate fund accounts consisting of the Vintage U.S. Government
              Obligation Fund, Vintage Limited Term Bond Fund, Vintage Equity
              Fund, Vintage Balanced Fund, AMCORE Stable Asset Fund, AMCORE
              Common Stock Fund, Loan Fund, Vintage Aggressive Growth Stock
              Fund, Vintage Technology Fund, Vintage Bond Fund, Gabelli Westwood
              Equity, Aetna Small Company, Putnam International Growth and the
              Contribution Fund. Participants have the option to invest their
              account balance and contributions to their respective account in
              these funds except the Loan Fund, Employer Matching Contribution
              Stock Fund, and Contribution Fund in increments of 5% of their
              participating balance. Participants are limited to a maximum
              contribution of 10% to the AMCORE Common Stock Fund. Participants
              also have the option to change the allocation of their individual
              participant's balance daily.

              The Plan provides that fund assets be invested as follows:

                    Vintage U.S. Government Obligation Fund investments consist
                    of U.S. government obligations, a money market mutual fund
                    that invests in U.S. government obligations, bonds,
                    debentures, commercial paper, bankers' acceptances, bank
                    certificates of deposit, and savings instruments.

                                                                     (Continued)


                         AMCORE FINANCIAL SECURITY PLAN

                          Notes to Financial Statements

                           December 31, 2001 and 2000


                    Vintage Limited Term Bond Fund investments consist of a
                    mutual fund that invests in U.S. government obligations,
                    bonds, debentures, commercial paper, bankers' acceptances,
                    mortgages, and savings instruments which mature beyond one
                    year.

                    Vintage Equity Fund investments consist of a mutual fund
                    that invests primarily in large capitalization equity
                    securities.

                    Vintage Balanced Fund is a mutual fund that invests in a
                    blend of large capitalization equity and debt securities.

                    AMCORE Stable Asset Fund is a common trust fund comprised
                    primarily of investments in high quality fixed and variable
                    rate insurance company contracts, as well as short-term
                    investments. The Plan provides that a minimum of 50% of
                    assets of this fund can be liquidated in 30 days and the
                    remainder within 12 months.

                    AMCORE Common Stock Fund consists solely of AFI common
                    stock, which is traded in the over-the-counter market under
                    the symbol "AMFI." The employees have voting rights in all
                    shares. Temporarily, assets are held in a money market fund
                    until the AFI stock is purchased.

                    Vintage Aggressive Growth Stock Fund consists of a mutual
                    fund that invests in relatively volatile small and
                    mid-capitalization equity securities that are poised for
                    above-average growth over the long term.

                    Contribution Fund serves as a temporary account to
                    accumulate contributions to be allocated to the other funds.
                    This fund invests in money market instruments.

                    Vintage Technology Fund consists of primarily domestic
                    securities, but also foreign companies in various industries
                    that are believed to benefit significantly from
                    technological advances or improvements without regard to
                    market capitalization.

                    Vintage Bond Fund primarily invests in bonds, notes, and
                    debentures of a wide range of domestic fixed-income security
                    issuers.

                    Gabelli Westwood Equity is a mutual fund that normally
                    invests at least 65% of assets in common stocks and
                    convertible securities of seasoned companies with historical
                    earnings growth higher than published indexes, and in
                    smaller companies believed to have outstanding potential for
                    capital appreciation. The fund may also invest up to 35% of
                    assets in foreign and domestic debt securities.

                    Aetna Small Company normally invests at least 65% of assets

                    emerging markets. It may engage in hedging strategies.

(5)    Transactions with Related Party

       Except for the common stock of the employer, Gabelli Westwood Equity,
       Aetna Small Company, and Putnam International Growth, all plan
       investments are shares of mutual funds, a common trust fund, and money
       market deposits which are managed by AMCORE Investment Group N.A., which
       is the trustee as defined by the Plan, and, therefore, these transactions
       qualify as party-in-interest. Effective June 1, 2000, AMCORE Investment
       Group became the Trustee of the Plan. Until June 1, 2000, BISYS served as
       the Plan Trustee.

       Certain costs of administering the Plan are paid by AMCORE Financial,
       Inc. (Plan Sponsor), the sponsor. Administrative expenses totaled $1,887
       and $59,682 for the years ended December 31, 2001 and 2000. The
       administration of the funds is now performed by the Plan Sponsor.
       Accordingly, the majority of the fees to the Plan have been waived.

(6)    Plan Termination

       Although it has not expressed any intent to do so, the employer 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, the net income or loss to the date of termination, less
       any distribution expenses and liquidation costs, shall be distributed
       proportionately to the participants' accounts and participants will be
       entitled to receive the value of their accounts.

(7)    Participant Loans

       Participants are eligible to obtain loans from the Plan in the event of
       financial hardship as defined by the Plan. The loans are limited to the
       lesser of $50,000 or 50% of the accrued benefit of the participant under
       the Plan, excluding the participant's accrued benefit attributable to the
       basic retirement account. Participants' loans are charged interest at a
       rate which is based on prime at the date of the loan and is fixed for the
       life of the loan. Loan terms range from 1-5 years or a greater period for
       loans made for the acquisition of a primary residence. Loan repayments
       are made through automatic payroll deductions from each regular check
       received by the participant. The loans are collateralized by the
       participants' vested interest in the Plan.

(8)    Income Tax Status

       The Internal Revenue Service has determined and informed the employer by
       letter dated April 28, 1995 that the Plan and related trust are designed
       in accordance with applicable sections of the Internal Revenue Code
       (IRC). The Internal Revenue Service has also determined and informed the
       Company by a letter dated April 28, 1995, that the Plan is qualified and
       trust established under the Plan is tax-exempt, under applicable sections
       of the Internal Revenue Code. The plan administrator believes that the
       Plan is designed and currently being operated in compliance with the
       applicable requirements of the IRC.

(9)    Additional Investments

       During 2001, AMCORE made three additional Mutual Funds available to plan
       participants: Gabelli Westwood Equity, Aetna Small Company, and Putnam
       International Growth.

(10)   Subsequent Events

       In January 2002, AMCORE made the PIMCO Innovation Fund, a mutual fund not
       affiliated with AFI, available to plan participants. This fund replaced
       the AMCORE Vintage Technology Fund.
