             Report of Independent Registered Public Accounting Firm


The Plan Administrator
Associated Banc-Corp
The CFG Salary Savings Plan and Trust:


We have audited the accompanying statements of net assets available for plan
benefits of The CFG Salary Savings Plan and Trust (Plan) as of January 22, 2004
and March 31, 2003 and the related statement of changes in net assets available
for plan benefits for the period from April 1, 2003 to January 22, 2004. These
financial statements are the responsibility of the Plan's administrator. Our
responsibility is to express an opinion on these financial statements based on
our audit.

We conducted our audits in accordance with the auditing standards of the Public
Company Accounting Oversight Board (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 the Plan administrator, 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
January 22, 2004 and March 31, 2003, and the changes in net assets available for
plan benefits for the period from April 1, 2003 to January 22, 2004, in
conformity with accounting principles generally accepted in the United States of
America.

THE CFG SALARY SAVINGS PLAN AND TRUST

Notes to Financial Statements

January 22, 2004 and March 31, 2003


(1)  Description of the Plan

     The following brief description of The CFG Salary Savings Plan and Trust
     (Plan) is provided for general information. Participants should refer to
     the summary plan description for a more complete description of the Plan's
     provisions.

     General

     The Plan is a defined contribution plan covering all employees of the
     former CFG Insurance Services and its subsidiaries (referred to herein as
     the Company) who have completed 1,000 hours of service and are age 18 or
     older. Associated Banc-Corp acquired 100% of the outstanding common shares
     of CFG in a transaction that was consummated on April 1, 2003. The Plan is
     subject to the provisions of the Employee Retirement Income Security Act of
     1974, as amended (ERISA), and is participant-directed.

     Plan Merger

     Effective January 22, 2004 the Plan merged with and all of the Plan's
     assets were transferred into the Associated Banc-Corp 401(k) Profit Sharing
     & Employee Stock Ownership Plan.

     Contributions

     Each year, participants may contribute up to 15% of pretax annual
     compensation, as defined in the Plan. Participants may also contribute
     amounts representing distributions from other qualified plans. The Company
     may contribute matching contributions up to the first 6% of base
     compensation that a participant contributes to the Plan. The Company may
     also contribute additional contributions at the discretion of the Company's
     board of directors. The Company's matching contribution was $337,091 for
     the period ended January 22, 2004. There were no discretionary
     contributions made for the same period.

     Participant Accounts

     Each participant's account is credited with the participant's contribution,
     individual account earnings, and allocations of the Company's matching and
     discretionary contributions. Allocations are based on participant
     contributions or eligible compensation, as defined by the Plan. The benefit
     to which a participant is entitled is limited to the balance in the
     participant's vested account.

     Vesting

     Participants are immediately vested in their pretax contributions plus
     actual earnings thereon. Vesting in the Company's matching and
     discretionary contribution portion of their account plus actual earnings
     thereon is based on years of credited service. A participant's account
     balance will vest in 20% increments after two years of credited service.
     These participants will be 100% vested after six years of credited service.
     A participant is also 100% vested upon reaching normal retirement age, upon
     death, or upon becoming partially or totally disabled.

     Forfeitures

     Forfeited non-vested accounts are used to reduce future employer
     contributions. As of January 22, 2004 forfeited non-vested accounts totaled
     $ 9,027, which were used to reduce the employer contribution made for the
     period ended January 22, 2004.

     Investment of Plan Assets

     Participants had the right to direct that investments be made in the
     Balanced Lifestage Fund, Growth Lifestage Fund, Growth Balanced Lifestage
     Fund, Conservative Balanced Lifestage Fund, Money Market Fund, Intermediate
     Term Bond Fund, Common Stock Fund, Foreign Equity Fund, Emerging Growth
     Fund, Equity Income Fund, Associated Banc-Corp Common Stock Fund, Dodge &
     Cox Stock Fund, EuroPacific Growth Fund, Goldman Sachs Growth Opportunities

     held in trust with a subsidiary of the Company (trustee). The following is
     a brief description of each fund:

     Balanced Lifestage Fund - The fund is designed to put equal emphasis on the
     pursuit of capital growth through investments in stocks, along with the
     stability and income generation provided by fixed income securities.
     Approximately one-half the portfolio will consist of investment grade bonds
     with the remaining one-half consisting of a diversified mix of stocks, with
     an emphasis on large company stocks but including small and foreign stocks.

     Growth Lifestage Fund - The fund is designed to achieve growth of capital
     through investment in a broadly diversified portfolio of common stocks. The
     portfolio will emphasize large capitalization stocks, but will also include
     mid-cap, small-cap, and foreign stocks.

     Growth Balanced Lifestage Fund - The fund is designed to seek both long
     term growth of capital and a modest amount of income and stability through
     a mix of stocks and bonds. The portfolio will largely emphasize the pursuit
     of capital growth through investments in stocks with the remainder
     primarily consisting of investment grade bonds.

     Conservative Balanced Lifestage Fund - The fund is designed to emphasize
     stability of principal and income through investments in fixed income
     securities with a smaller emphasis on capital growth through investment
     stocks. The portfolio will primarily consist of investment grade bonds with
     the remainder consisting of large company stocks.

     Money Market Fund - The fund is designed to provide safety of principal.
     Actual investments made by the trustee are into the Associated Trust
     Company, N.A. Cash Management Fund.

     Intermediate Term Bond Fund - The fund is designed to earn a competitive
     total return through diversified investment in high-quality fixed income
     securities issued by the United States Government, federal agencies, and
     public corporations, as well as mortgage-backed and asset-

     backed issues and certificates of deposit.

     through investment in large cap companies with good growth prospects. The
     majority of the assets in this portfolio are included in the S&P 500 Index.

     investment opportunities outside the United States. The fund invests
     primarily in attractively valued foreign common stocks.

     Emerging Growth Fund - The fund is designed to maximize long-term stock
     returns by diversifying stock ownership into numerous industries. The fund
     invests in equities issued by small capitalization, fast growing companies.

     Equity Income Fund - The fund is designed to pursue growth of capital while
     providing above average dividend yield. The fund invests in common stocks
     believed to be undervalued.

     Associated Banc-Corp Common Stock Fund - The fund is designed to share in
     the performance of Associated Banc-Corp. The fund invests in Associated
     Banc-Corp common stock and cash equivalents.

     Dodge & Cox Stock Fund - The fund is designed to pursue long-term growth of
     principal and income. Fund intends to remain fully invested in equities
     with at least 65% of assets in common stocks.

     EuroPacific Growth Fund - The fund is designed to pursue long-term growth
     of capital. The fund invests in at least 80% of assets in equity securities
     of issuers from Europe and the pacific Basin.

     long-term growth of capital. The fund invests in at least 90% of assets in
     equity securities with a primary focus on mid-cap companies.

     Janus Small Cap Value Fund - The fund is designed to achieve capital
     appreciation. The fund invests in at least 80% of assets in equity
     securities of undervalued small companies with market capitalization within
     the 12-month average of the capitalization range of the Russell 2000 index.

     capital growth. The fund invests primarily in small capitalization growth
     companies.

     Vanguard 500 Index Fund - The fund seeks to track the S&P 500 Index as
     closely as possible by investing in each of the Index 500 stocks according
     to each stock's weighting in the Index.

THE CFG SALARY SAVINGS PLAN AND TRUST

Notes to Financial Statements

January 22, 2004 and March 31, 2003

     Weitz Value Fund - The fund is designed to achieve capital appreciation by
     investing primarily in equity securities. The advisor seeks securities
     trading at prices lower than their intrinsic values.

     Participants can elect to invest in one of the aforementioned funds or in
     1% increments in two or more funds. Participants can change the allocation
     of the Plan accounts on a daily basis.

     Participant Loans

     Participants may borrow from their fund accounts a minimum of $1,000 up to
     a maximum equal to the lesser of $50,000 or 50% of their vested account
     balance. Loan transactions are treated as a transfer between the individual
     participant's selected investment fund account(s) and the participant note
     account. Loan terms range from one to five years or up to 15 years if
     related to the purchase of a primary residence. The loans are secured by
     the balance in the participant's account and bear a market rate of interest
     comparable to what a bank or other professional lender would charge, fixed
     for the duration of the loan. Principal and interest is paid ratably
     through bi-weekly payroll deductions.

     Valuation of Plan Assets

     Plan assets are valued daily. Under a daily valued plan, participants can
     verify account balances daily utilizing the VRU (Voice Response Unit) or
     Internet access, contributions are allocated to participant accounts upon
     receipt, and income and changes in asset values are immediately updated.

     Distributions

     On termination of service due to death, disability, or retirement, a
     participant may elect to receive either an annuity or a lump-sum amount
     equal to the value of the participant's vested interest in his or her
     account. Distributions may also be made in the form of hardship
     withdrawals.

(2)  Summary of Significant Accounting Policies

     Basis of Presentation

     The accompanying financial statements have been prepared on the accrual
     basis of accounting and present the net assets available for plan benefits
     and changes in those net assets in accordance with accounting principles
     generally accepted in the United States of America. The significant
     accounting policies of the Plan are as follows:

     Investments and Income Recognition

     Investment securities are valued at quoted market prices. Mutual funds are
     valued at the

                                        7


THE CFG SALARY SAVINGS PLAN AND TRUST

Notes to Financial Statements

January 22, 2004 and March 31, 2003

     reported net asset value. The investments in units of the common/collective
     trust funds are valued at the amount at which shares in the funds can be
     withdrawn, which approximates fair value. Securities for which no quoted
     market price is available are valued at estimated fair value. Short-term
     investments are stated at cost plus accrued interest, which approximates
     fair value. Participant loans are valued at cost which approximates fair
     value. Plan assets are held with the trustee. Purchases and sales of
     securities are recorded on a trade-date basis. Realized gains and losses on
     the sale of investments are determined through the use of specific
     identification. Interest income is recorded on the accrual basis and
     dividends on the ex-dividend date.

     The Plan's investments are exposed to various risks, such as interest rate,
     market and credit risks. Due to the level of risk associated with certain
     investments and the level of uncertainty related to changes in the values
     of investments, it is at least reasonably possible that changes in risks in
     the near term could materially affect participant account balances and the
     amounts reported in the financial statements of the Plan.

     Payment of Benefits

     Benefits are recorded when paid.

     Use of Estimates

     The preparation of financial statements in conformity with accounting
     principles generally accepted in the United States of America requires plan
     administrator estimates and assumptions that affect the reported amounts of
     assets available for benefits and plan benefit obligations and disclosure
     of contingent assets and liabilities at the date of the financial
     statements. Actual results could differ from those estimates.

(3)  Investments

     The fair value of investments that represent 5% or more of the Plan's net
     assets at January 22, 2004 and March 31, 2003 are presented in the
     following table:
