ITEM 1.  Financial Statements Continued:

                              ASSOCIATED BANC-CORP
                   Notes to Consolidated Financial Statements

NOTE 1:  Basis of Presentation

In the opinion of management,  the accompanying unaudited consolidated financial
statements  contain  all  adjustments  necessary  to present  fairly  Associated
Banc-Corp's  ("Corporation")  financial position,  results of its operations and
cash flows for the periods  presented,  and all such adjustments are of a normal
recurring nature. The consolidated  financial statements include the accounts of
all  subsidiaries.  All  material  intercompany  transactions  and  balances are
eliminated.   The  results  of  operations  for  the  interim  periods  are  not
necessarily indicative of the results to be expected for the full year.

These interim consolidated  financial statements have been prepared according to
the rules  and  regulations  of the  Securities  and  Exchange  Commission  and,
therefore,  certain information and footnote  disclosures  normally presented in
accordance with accounting principles generally accepted in the United States of
America  have been  omitted or  abbreviated.  The  information  contained in the
consolidated financial statements and footnotes in the Corporation's 2000 annual
report on Form 10-K,  should be  referred to in  connection  with the reading of
these unaudited interim financial statements.

In preparing the consolidated  financial  statements,  management is required to
make estimates and  assumptions  that affect the reported  amounts of assets and
liabilities  as of the date of the balance  sheet and  revenues and expenses for
the period.  Actual  results could differ  significantly  from those  estimates.
Estimates that are  particularly  susceptible to significant  change include the
determination  of the  allowance for loan losses and the valuation of investment
securities and mortgage servicing rights.

NOTE 2:  Reclassifications

Certain  items in prior  period  consolidated  financial  statements  have  been
reclassified to conform with the March 31, 2001 presentation.

NOTE 3:  Adoption of Statements of Financial Accounting Standards ("SFAS")

As  required,  on  January  1,  2001  the  Corporation  adopted  SFAS  No.  133,
"Accounting for Derivative  Instruments  and Hedging  Activities," as amended by
SFAS No. 137,  "Accounting for Derivative  Instruments and Hedging  Activities -
Deferral of the  Effective  Date of FASB  Statement  No. 133," and SFAS No. 138,
"Accounting for Certain Derivative  Instruments and Certain Hedging Activities,"
(collectively referred to as "SFAS No. 133" or as the "statement"). The adoption
of  SFAS  No.  133  had  an  immaterial  impact  on the  consolidated  financial
statements.  See Note 5 of the notes to consolidated  financial statements for a
more detailed discussion.

SFAS No. 140,  "Accounting  for Transfers and Servicing of Financial  Assets and
Extinguishments  of  Liabilities,"   replaces  SFAS  No.  125,  "Accounting  for
Transfers and Servicing of Financial Assets and Extinguishments of Liabilities,"
and rescinds SFAS No. 127, "Deferral of the Effective Date of Certain Provisions
of SFAS No.  125." The  statement  revises  the  standards  for  accounting  for
securitizations  and other  transfers of financial  assets and requires  certain
disclosures,  but it also  carries over most of the  provisions  of SFAS No. 125
without modification.  The statement provides accounting and reporting standards
for  transfers  and  servicing  of  financial  assets  and   extinguishments  of
liabilities  based on the  application of a financial  components  approach that
focuses on control.  It is effective for transactions  occurring after March 31,
2001, and is to be applied  prospectively with certain exceptions.  The adoption
is not  expected  to be  material  to the


                                       7




Corporation's  financial  position or results of operations.

NOTE 4:  Earnings Per Share

Basic  earnings  per share is  calculated  by dividing  net income  available to
common stockholders by the weighted average number of common shares outstanding.
Diluted  earnings per share is calculated by dividing net income by the weighted
average number of shares adjusted for the dilutive  effect of outstanding  stock
options.

Presented below are the calculations for basic and diluted earnings per share:

NOTE 5:  Derivatives and Hedging Activities

Effective  January 1, 2001, the Corporation  adopted SFAS 133, which establishes
accounting and reporting standards for derivative instruments, including certain
derivative  instruments  embedded in other contracts and for hedging activities.
All  derivatives,  whether  designated  in  hedging  relationships  or not,  are
required to be recorded on the balance sheet at fair value. If the derivative is
designated  as a fair  value  hedge,  the  changes  in  the  fair  value  of the
derivative and of the hedged item attributable to the hedged risk are recognized
in earnings. If the derivative is designated as a cash flow hedge, the effective
portions of changes in the fair value of the  derivative  are  recorded in other
comprehensive income ("OCI") and are recognized in the income statement when the
hedged item affects earnings.  Ineffective portions of changes in the fair value
of cash flow hedges are recognized in earnings.

The Corporation uses derivative  instruments  primarily to hedge the variability
in  interest  payments or protect  the value of certain  assets and  liabilities
recorded on its balance sheet from changes in interest  rates.  The  predominant
activities  affected by the statement  include the Corporation's use of interest
rate  swaps  and  certain  mortgage  banking  activities.  The  adoption  of the
statement included the following:

- -    Under SFAS No. 133, the Corporation  was allowed a one-time  opportunity to
     reclassify   investment   assets   from    held-to-maturity    ("HTM")   to
     available-for-sale   ("AFS").   Thus   upon   adoption,   the   Corporation
     reclassified  all its HTM  securities to AFS. The  amortized  cost and fair
     value of the  securities  transferred  were $369 million and $373  million,
     respectively.

- -    The Corporation designated its interest rate swaps existing at December 31,
     2000,  to qualify for hedge  accounting.  The swaps  hedge the  exposure to
     variability in interest payments of variable rate liabilities. These hedges
     represent  cash flow  hedges and were  highly  effective  at  adoption.  On
     adoption,  the cumulative effect, net of taxes of $843,000, was recorded as
     a decrease to OCI of $1.3 million.



                                       8


- -    The Corporation's  commitments to sell groups of residential mortgage loans
     that it originates or purchases as part of its mortgage  banking  business,
     as well as its  commitments  to originate  residential  mortgage  loans are
     considered  derivatives  under  SFAS  No.  133.  The  fair  value  of these
     derivatives at adoption,  an $11,000 net gain, was recorded directly to the
     consolidated statements of income in mortgage banking income.

In accordance with the statement,  the Corporation measures the effectiveness of
its hedges on a periodic basis. Any difference  between the fair value change of
the hedge  versus the fair value change of the hedged item is  considered  to be
the "ineffective"  portion of the hedge. The ineffective portion of the hedge is
recorded  as  an  increase   or  decrease  in  the  related   income   statement
classification of the item being hedged. For the mortgage  derivatives which are
not accounted for as hedges, changes in fair value are recorded as an adjustment
to mortgage banking income.

At March 31,  2001,  the swaps  designated  as cash flow  hedges have a notional
amount of $300 million,  have a weighted  average  pay/receive rate of 6.36% and
6.06%, respectively,  and a weighted average maturity of 14 months. At March 31,
2001,  the  estimated  fair value of the swaps was a $6.2 million  loss, or $3.7
million, net of taxes of $2.5 million,  carried as a component of OCI. There was
no ineffective  portion to be recorded.  Currently,  none of the existing losses
within OCI are  expected to be  reclassified  into  earnings  within the next 12
months.

At March 31, 2001, a swap designated as a fair value hedge had a notional amount
of $3  million,  a  weighted  average  pay/receive  rate  of  7.55%  and  7.49%,
respectively,  and a weighted average maturity of 59 months.  The change in fair
value of the mortgage  derivatives since adoption of SFAS 133 was $634,000,  and
is recorded  in mortgage  banking  income for the three  months  ended March 31,
2001.

NOTE 6:  Segment Reporting

SFAS  No.  131,  "Disclosures  about  Segments  of  an  Enterprise  and  Related
Information,"  requires  selected  financial and descriptive  information  about
reportable  operating  segments.  The  statement  uses a  "management  approach"
concept  as the  basis  for  identifying  reportable  segments.  The  management
approach is based on the way that  management  organizes the segments within the
enterprise for making operating decisions,  allocating resources,  and assessing
performance.  Consequently,  the segments are evident from the  structure of the
enterprise's  internal  organization,  focusing on financial information that an
enterprise's  chief  operating  decision-makers  use to make decisions about the
enterprise's operating matters.

The Corporation's reportable segment is banking, conducted through its bank,
leasing, mortgage, insurance and brokerage subsidiaries. For purposes of segment
disclosure under this statement, these entities have similar economic
characteristics and the nature of their products, services, processes,
customers, delivery channels and regulatory environment are similar.

The "other" segment is comprised of smaller nonreportable segments, including
asset management, consumer finance, treasury, holding company investments, as
well as inter-segment eliminations and residual revenues and expenses,
representing the difference between actual amounts incurred and the amounts
allocated to operating segments.

those expressed in forward-looking  statements contained in this document. These
factors include the following:

- -    operating, legal, and regulatory risks;

- -    economic,  political,  and competitive  forces affecting the  Corporation's
     banking, securities, asset management, and credit services businesses; and

- -    the risk that the Corporation's analyses of these risks and forces could be
     incorrect  and/or that the  strategies  developed  to address them could be
     unsuccessful.

These factors should be considered in evaluating the forward-looking statements,
and undue reliance should not be placed on such statements.

Overview

The   following   discussion   and  analysis  is  presented  to  assist  in  the
understanding  and  evaluation  of the  Corporation's  financial  condition  and
results of operations.  It is intended to complement the unaudited  consolidated
financial  statements,  footnotes,  and  supplemental  financial  data appearing
elsewhere in this Form 10-Q and should be read in conjunction therewith.

Management  continually evaluates strategic acquisition  opportunities and other
various  strategic  alternatives  that could involve the sale or  acquisition of
branches or other assets, or the consolidation or creation of subsidiaries.

Results of Operations - Summary

Net income for the three  months  ended March 31, 2001  ("1Q01")  totaled  $42.1
million,  or $.64 and $.63 for basic and  diluted  earnings  per share  ("EPS"),
respectively.  Comparatively,  net income for the first quarter of 2000 ("1Q00")
was  $43.1  million,  or $.62 for  both  basic  and  diluted  EPS.  For 1Q01 the
annualized  return on average assets ("ROA") was 1.31% and the annualized return
on  average   equity   ("ROE")  was  17.18%,   compared  to  1.38%  and  19.33%,
respectively,  for the comparable  period in 2000.  The net interest  margin for
1Q01 was 3.34% compared to 3.46% for 1Q00.

Net Interest Income and Net Interest Margin

Net  interest  income on a fully  taxable  equivalent  basis ("FTE NII") for the
three months  ended March 31, 2001,  was $102.6  million,  relatively  unchanged
(down  $462,000,  or less than 1%) from the  comparable  quarter  last year.  As
indicated  in Tables 2 and 3, the  $462,000  decrease in FTE NII was due to rate
(as the impact of changes in the interest  rate  environment  reduced FTE NII by
$3.2 million),  and volume (with balance sheet growth and differences in the mix
of average  earning  assets  ("EAs")  and average  interest-bearing  liabilities
("IBLs") adding $2.7 million to FTE NII).

FTE NII and net  interest  margin  ("NIM")  have been  impacted  by  competitive
pricing pressures and the interest rate environment.  Interest rates fell during
1Q01, but rose during 1Q00. Comparatively,  while the average Federal funds rate
for 1Q01 was only 8 basis points  ("bp") lower than for 1Q00,  the rate at March
31, 2001 was 100 bp lower than that at March 31, 2000.

The NIM for 1Q01 was  3.34%,  down 12 bp from  3.46%  in 1Q00.  This  comparable
quarter  decline is  attributable  to an 18 bp decrease in interest rate spread,
offset in part by a 6 bp higher  contribution  from net free funds. The yield on
EAs was 7.87% for 1Q01,  up 21 bp over the  comparable  quarter  last year.  The
average loan yield was 8.25%,  up 13 bp over 1Q00. This was primarily a function
of increasing  the mix of commercial  loans to total loans,  which are generally
higher-yielding. The average investment yield was 6.81%, up 31 bp over 1Q00, due
to the rising rate environment during 2000.  Finally,  the increase in the yield
on EAs was  impacted by the mix of loans and  investments.  The ratio of average
loans to EAs (representing 73.7% of EAs for 1Q01 compared to 71.4% for 1Q00).

The cost of IBLs was 5.11% for 1Q01, up 39 bp compared to 1Q00. The average cost
of  interest-bearing  deposits  excluding  brokered CDs was 4.65%, up 42 bp over
1Q00, primarily in the cost of time deposits and money market accounts, impacted
strongly  by  competitive  pricing  pressures  and the higher  rate  environment
through the year 2000.  The cost of brokered CDs was 6.53%,  up 62 bp over 1Q00,
also impacted by the


                                       12


higher rate  environment  during 2000.  The cost of wholesale  funds was up 6 bp
between  comparable first quarter periods.  Given the growth in EAs, the decline
in interest-bearing deposit balances (excluding brokered CDs), and other funding
needs (such as funding the Corporation's  share repurchases during 2000) between
comparable quarters,  there was greater reliance on higher-costing  brokered CDs
and wholesale funds (which on a combined basis  represented  34.9% of total IBLs
in 1Q01 versus 31.5% last year).

EAs  increased by $355  million  (3.0%) over the  comparable  quarter last year,
while IBLs grew $265 million  (2.5%).  The growth in EAs came from loans,  up an
average  of $526  million  (6.2%);  excluding  the  impact  of the  credit  card
receivables  sale,  loans  were  up  $654  million  (7.7%).  In  line  with  the
Corporation's  focus  on  increasing  the  mix  of  commercial  lending  in  its
portfolio,   the  growth  was  predominantly  from  commercial  loans.   Average
investments  decreased  $171  million  (5.1%),  attributable  primarily to lower
average mortgage related securities and US government  agencies.  IBLs increased
$265 million or 2.5%. The growth in IBLs is attributed primarily to increases in
wholesale  funding  and  brokered  CDs,  which on a combined  basis were up $442
million, offset by a decline in interest-bearing deposits of $177 million.

Provision for Loan Losses

The  provision for loan losses  ("PFLL") for 1Q01 was $5.6 million,  up $379,000
from  4Q00 of  $5.2  million,  and  down  slightly  from  1Q00 of $5.7  million.
Annualized  net  charge-offs as a percent of average loans for 1Q01 decreased to
0.10%  from  0.11% and 0.12% for 4Q00 and 1Q00,  respectively.  The ratio of the
allowance  for loan  losses to total  loans  was  1.38%,  up from  1.35% at both
December 31, and March 31, 2000. See Table 8.

The PFLL is  predominantly a function of the  methodology  used to determine the
adequacy of the  allowance  for loan losses which focuses on changes in the size
and  character  of the loan  portfolio,  changes in levels of impaired and other
nonperforming  loans,  historical  losses on each portfolio  category,  the risk
inherent in specific  loans,  concentrations  of loans to specific  borrowers or
industries,   existing  economic  conditions,   the  fair  value  of  underlying
collateral,  and other factors which could affect potential  credit losses.  See
additional discussion under the "Allowance for Loan Losses" section.

Noninterest Income

Noninterest  income for 1Q01 was $44.3  million,  down $1.6 million or 3.5% from
1Q00. Primary components  impacting the change between comparable  quarters were
mortgage  banking income (which  increased  $4.6 million),  and the combined net
gains (losses) on investment  securities  and asset sales,  which were down $5.8
million. Noninterest income excluding these items was relatively unchanged, down
$425,000 or 1.2%.

Trust  service fees  decreased  $2.1 million  between  comparable  first quarter
periods.  The change was  predominantly due to a decrease in the market value of
assets  under  management,  a  function  of the  declines  in the stock and bond
markets between the first quarter periods, and competitive market conditions.

Service  charges on deposit  accounts  were up $1.3 million  between  comparable
first quarter  periods,  primarily due to 1Q01 benefiting from the 2000 mid-year
rate increases in NSF/OD charges.

Mortgage banking income consists of servicing fees, the gain or loss on sales of
mortgage  loans to the  secondary  market,  gains or  sales  of  servicing,  and
production-related  revenue (origination,  underwriting and escrow waiver fees).
Mortgage  banking  income  increased  $4.6  million,  twice the 1Q00 level.  The
increase was primarily a result of a significant  increase in secondary mortgage
loan  production and related sales between  comparable  periods ($345 million in
1Q01  versus $60  million  in 1Q00).  The higher  production  levels  positively
impacted gains on sales (up $3.5 million, of which, $645,000 is related to gains
in the fair value of mortgage  derivatives  and $1.1 million was due to the sale
of  servicing)  and volume  related fees (up  $600,000).  The portfolio of loans
serviced for others was relatively unchanged ($5.5 billion at 1Q01, down 1% from
$5.6 billion at 1Q00).

Credit card and other nondeposit fees were $6.8 million for 1Q01, an increase of
$1.5 million or 28.6% over 1Q00, with $366,000 in increased  merchant income and
$1.1 million in all other credit card revenue. The other credit card revenue was
enhanced by the April 2000 acquisition  agreement and five-year agency agreement
with Citibank USA ("Citi")  which provide for agent fees and other income on new
and existing card business.

Retail  commission  income  (which  includes   commissions  from  insurance  and
brokerage  product sales) was down $1.1 million compared to 1Q00,  primarily due
to a weaker  stock  market  and lower  interest  rate  environment  between  the
comparable quarters.  Insurance  commissions declined $611,000,  while brokerage
commissions declined $514,000.

BOLI income was $3.1  million,  up  $235,000  or 8.1% over 1Q00.  BOLI income is
included in other noninterest income on the consolidated statements of income.


                                       15


Asset  sale  gains,   net,   decreased  $7.7  million  from  1Q00,   principally
attributable  to the $8.2 million net premium on deposits of five  branches sold
during 1Q00.

Investment securities gains (losses), net, increased $1.9 million from 1Q00. The
1Q00 net losses of $1.7 million were from securities  sold to mitigate  interest
rate risk and enhance future yields.

Noninterest Expense

Noninterest  expense ("NIE") remained  relatively  unchanged between  comparable
periods,  at $78.5  million for 1Q01  versus  $78.6  million for 1Q00.  However,
excluding a $1.6  million  valuation  adjustment  on mortgage  servicing  rights
("MSRs") in 1Q01  (discussed  below),  NIE was $1.8  million (2%) lower than the
same quarter last year.

Personnel  expense  increased  $1.7 million or 4.3% over 1Q00,  and  represented
51.4% of total NIE in 1Q01 compared to 49.2% in 1Q00. Salary expenses  increased
$555,000 or 1.8% between comparable quarters,  due primarily to merit increases,
partially  offset by the decline in  full-time  equivalent  employees  ("FTEs").
Average FTEs were down 97 employees or 2.5% to 3,840 for 1Q01.  Fringe  benefits
increased  $1.1 million  (14.2%) over 1Q00,  primarily  the result of increasing
health insurance costs.

Occupancy  expense  increased  primarily  due to rate  increases  in  utilities.
Equipment expense declined  predominantly in computer depreciation expense. Data
processing  costs  decreased  due to the lower  overall  vendor  costs and lower
credit card  processing  costs given the sale of the credit card  receivables in
April  2000.  Business  development  and  advertising  declined,   primarily  in
television advertising.

MSR  amortization  expense  includes  the  amortization  of the  MSR  asset  and
increases or decreases to the valuation allowance associated with the MSR asset.
Amortization of MSRs increased by $1.5 million between the comparable  quarters,
predominantly  driven by the  addition of a $1.6  million  valuation  adjustment
during 1Q01. Legal and professional  fees were down $702,000 between  comparable
quarters.

Other  expense  was $11.2  million,  down $1.0  million  from 1Q00,  principally
attributable to declines in ATM related  processing  costs and losses other than
loans.

Income Taxes

Income tax expense for 1Q01 was $15.2 million,  down $1.7 million from 1Q00. The
effective tax rate (income tax expense divided by income before taxes) was 26.5%
and 28.2% for 1Q01 and 1Q00, respectively. This decrease is primarily the result
of the tax benefit of increased  municipal  securities  (the average  balance of
municipal securities  increased 19% since 1Q00),  increased BOLI income, and the
effect of real estate investment trusts.

Balance Sheet

At March 31, 2001, total assets were $13.1 billion, an increase of $388 million,
or 3.0%,  over March 31, 2000.  Loan growth since 1Q00 was $346 million or 4.0%,
almost  exclusively in commercial loans,  which now comprise 53% of total loans,
consistent with Corporate strategies. Loans held for sale grew $115 million as a
result of the increased  residential  mortgage  activity between periods.  Total
deposits  were down $510  million or 5.5%;  however,  total  deposits  excluding
brokered  CDs  ("retail  deposits")  were down $177  million  or 2.1%,  with $26
million  attributable  to a 1Q00 branch deposit sale.  Demand  deposits grew $97
million (8.7%), representing 14% of total deposits and representing 15% of total
retail deposits at March 31, 2001, compared to 13% a year earlier.

Since  year-end 2000,  total assets have remained level at $13.1 billion.  Loans
increased moderately, up $22 million, to $8.9 billion at March 31, 2001.

On average,  total assets for 1Q01 increased to $13.0  billion,  or $442 million
(3.5%)  over  1Q00.  Average  earning  assets for 1Q01 were  $12.2  billion,  an
increase of $355 million over 1Q00.  Loan growth  accounted for  essentially all
the earning asset growth. For more information on average balances, refer to the
section titled "Net Interest Income and Net Interest Margin."

Allowance for Loan Losses

The loan  portfolio is the  Corporation's  primary asset subject to credit risk.
Credit risk is controlled and monitored through the use of lending standards,  a
thorough  review of potential  borrowers,  and  on-going  review of loan payment
performance.  Active asset quality administration,  including early problem loan
identification  and timely resolution of problems,  further ensures  appropriate
management of credit risk and minimization of loan losses.

As of March 31, 2001, the allowance for loan losses ("AFLL") was $123.7 million,
representing 1.38% of loans outstanding, compared to $116.3 million, or 1.35% of
loans,  at March 31, 2000,  and $120.2  million,  or 1.35% at year-end  2000. At
March 31, 2001,  the AFLL was 224% of  nonperforming  loans compared to 311% and
252%  at  March  31 and  December  31,  2000,  respectively.  Table  8  provides
additional information regarding activity in the AFLL.

The AFLL at March 31, 2001  increased  $7.4 million  (6.3%) since March 31, 2000
and $3.5 million  (2.9%) since  December 31, 2000.  The increase is, in part, in
response to continued  growth in commercial  loans,  which by their nature carry
greater  inherent  risk,  and  the  increase  in  nonperforming   loans  between
comparable periods (see Table 8 and section  "Nonperforming Loans and Other Real
Estate  Owned").  Loans at March 31, 2001,  grew $346 million (4.0%) since March
31, 2000,  predominately  in commercial  loans (see CF&A loans,  commercial real
estate and real estate construction loans included in Table 6). Period end loans
grew $22 million (1.0% annualized)  since year-end.  The mix of commercial loans
increased  as a percent of total loans to 53% at March 31, 2001  compared to 48%
at March 31, 2000 and 52% at December 31, 2000.

Charge-offs  were $2.9 million for the three months ending March 31, 2001,  $3.3
million for the  comparable  period  ending March 31, 2000 and $11.2 million for
year-end 2000, while recoveries for the corresponding periods were $0.8 million,
$0.7 million and $2.2 million,  respectively.  As a result, the ratio of NCOs to
average loans on an annualized basis was 0.10%, 0.12%, and 0.10% for 1Q01, 1Q00,
and for the 2000  year,  respectively.  With  the  slowing  economy,  management
expects higher levels of net charge-offs for the remainder of the year.

The AFLL represents  management's  estimate of an amount adequate to provide for
probable  credit  losses  in the  loan  portfolio  at the  balance  sheet  date.
Management's  evaluation  of the  adequacy of the AFLL is based on  management's
ongoing  review and grading of the loan  portfolio,  consideration  of past loan
loss   experience,   trends   in  past  due  and   nonperforming   loans,   risk
characteristics  of the  various  classifications  of loans,  existing  economic
conditions,  the fair value of  underlying  collateral,  and other factors which
could affect probable credit losses. Thus, in general, the change in the AFLL is
a function of a number of factors,  including  but not limited to changes in the
loan portfolio (see Table 6), NCOs and nonperforming loans (see Table 8).


                                       19


Management  believes the AFLL to be adequate at March 31, 2001. While management
uses available  information to recognize losses on loans,  future adjustments to
the AFLL may be necessary based on changes in economic conditions and the impact
of such change on the  Corporation's  borrowers.  As an  integral  part of their
examination  process,  various  regulatory  agencies also review the AFLL.  Such
agencies may require that  changes in the AFLL be  recognized  when their credit
evaluations  differ from those of  management,  based on their  judgments  about
information available to them at the time of their examination.

Nonperforming Loans and Other Real Estate Owned

Management   is  committed  to  an  aggressive   nonaccrual   and  problem  loan
identification  philosophy.  This  philosophy  is  embodied  through the ongoing
monitoring  and  reviewing of all pools of risk in the loan  portfolio to ensure
that problem loans are identified quickly and the risk of loss is minimized.

Nonperforming  loans  ("NPLs") are  considered an indicator of potential  future
loan losses.  NPLs are defined as nonaccrual  loans,  loans 90 days or more past
due but still accruing and  restructured  loans.  The  Corporation  specifically
excludes  student  loan  balances  that are 90 days or more  past due and  still
accruing and that have  contractual  government  guarantees  as to collection of
principal and interest,  from its  definition of NPLs. The  Corporation  had $20
million,  $20 million and $16 million of these loans at March 31, 2001, December
31, 2000, and March 31, 2000, respectively.

Table 8 provides detailed information regarding nonperforming assets. Total NPLs
at March 31, 2001 were up $7.5 million and $17.9  million,  from year-end  2000,
and 1Q00, respectively. The ratio of nonperforming loans to total loans was .62%
at 1Q01, as compared to .54% and .43% at year-end 2000, and 1Q00,  respectively.
Nonaccrual  loans account for the majority of the $17.9 million increase in NPLs
between the comparable first quarter  periods,  with nonaccrual loans increasing
$17.6 million (of which, $15.4 million was attributable to the addition of three
large commercial credits). Nonaccrual loans also account for the majority of the
$7.5 million  increase in NPLs since year-end 2000.  Nonaccrual  loans increased
$9.2  million (of which,  $8.2 million was  attributable  to the addition of two
large  commercial  credits),  accruing  loans past due 90 or more days decreased
$1.7  million  (due to the  transfer  of one large  commercial  credit from this
category to the nonaccrual  category),  and  restructured  loans were relatively
unchanged.

OREO was $3.3 million at 1Q01, down slightly  ($747,000) from December 31, 2000,
and relatively unchanged from 1Q00.

Potential  problem  loans are loans  where there are doubts as to the ability of
the borrower to comply with present  repayment terms. The decision of management
to place loans in this category does not  necessarily  mean that the Corporation
expects losses to occur but that  management  recognizes that a higher degree of
risk is associated with these  performing  loans.  At March 31, 2001,  potential
problem  loans  totaled  $157  million.  The loans  that have been  reported  as
potential  problem  loans  are  not  concentrated  in  a  particular   industry.
Management  does not presently  expect  significant  losses from credits in this
category.

Liquidity

Effective liquidity  management ensures the cash flow requirements of depositors
and borrowers, as well as the operating cash needs of the Corporation, are met.


                                       20


Funds  are  available  from  a  number  of  sources,  including  the  securities
portfolio,  the core deposit base, lines of credit with major banks, the ability
to acquire large and brokered deposits, and the ability to securitize or package
loans for sale.  Additionally,  liquidity is provided from loans and  securities
repayments and maturities.

During 2000,  the four  largest  subsidiary  banks  (Associated  Bank  Illinois,
National  Association,  Associated  Bank  Milwaukee,  Associated Bank Green Bay,
National Association, and Associated Bank North) established a $2.0 billion bank
note program.  Under this program,  short-term and long-term debt may be issued.
As of March 31, 2001, there was $2.0 billion available under this program.

The parent company's primary funding sources to meet its liquidity  requirements
are dividends and service fees from  subsidiaries,  borrowings with major banks,
commercial paper issuance,  and proceeds from the issuance of equity. The parent
company  manages its  liquidity  position to provide the funds  necessary to pay
dividends to  stockholders,  service debt,  invest in  subsidiaries,  repurchase
common stock, and satisfy other operating requirements. Additionally, the parent
company  had $200  million of  established  lines of credit  with  nonaffiliated
banks,  of which $82 million was  outstanding at March 31, 2001.  During 2000, a
$200  million  commercial  paper  program  was  initiated,  of which  $54.7  was
outstanding at March 31, 2001.

The subsidiary  banks are subject to regulation and, among other things,  may be
limited  in their  ability  to pay  dividends  or  transfer  funds to the parent
company.  Accordingly,  consolidated cash flows as presented in the consolidated
statements of cash flows may not represent  cash  immediately  available for the
payment of cash dividends to the Corporation's stockholders.

The parent company and its four largest  subsidiary  banks are rated by Moody's,
Standard  and  Poor's  (S&P),   and  Fitch.   These  ratings,   along  with  the
Corporation's  other ratings,  provide  opportunity for greater funding capacity
and funding alternatives.

Capital

On April 26, 2000, the Board of Directors ("BOD") declared a 10% stock dividend,
payable  June 15 to  shareholders  of record at the close of business on June 1.
All  share  and  per  share  data  in the  accompanying  consolidated  financial
statements has been adjusted to reflect the 10% stock dividend paid.

Stockholders'  equity at March 31, 2001  increased to $1.0 billion,  compared to
$920.8 million at March 31, 2000. The increase in equity between the two periods
was  primarily  composed of the  retention of earnings and the exercise of stock
options,  with offsetting  decreases to equity from the payment of dividends and
the repurchase of common stock. Additionally,  stockholders' equity at March 31,
2001,   included  $49.2  million  related  to  unrealized  gains  on  securities
available-for-sale,  net of the tax  effect.  At March 31,  2000,  stockholders'
equity  included  $43.6  million  related  to  unrealized  losses on  securities
available-for-sale,  net of the  tax  effect.  Excluding  the  unrealized  gains
(losses)  on  securities  AFS,  net of the tax effect,  stockholders'  equity to
assets would be 7.46% and 7.55% at March 31, 2001 and 2000, respectively.

Stockholders'  equity grew $55.0 million since  year-end  2000.  The increase in
equity  between the two  periods was  primarily  composed  of the  retention  of
earnings and the exercise of stock options,  with offsetting decreases to equity
from the payment of dividends and the repurchase of common stock.  Additionally,
stockholders'  equity at year-end,  included $15.6 million related to unrealized
gains on  securities  available-for-sale,  net of the tax effect.  Excluding the
unrealized   gains   (losses)  on  securities   AFS,  net  of  the  tax  effect,
stockholders'  equity to assets  would be 7.46% and 7.27% at March 31,  2001 and
December 31, 2000, respectively.

Cash dividends of $0.29 per share were paid in 1Q01, compared to $0.26 per share
in 1Q00, an increase of 10.0%.


                                       21



The BOD has  authorized  management  to repurchase  shares of the  Corporation's
common stock each quarter in the market,  to be made  available  for issuance in
connection  with  the  Corporation's  employee  incentive  plans  and for  other
corporate  purposes.  The BOD  authorized the repurchase of up to 330,000 shares
per quarter in 2001.  During 1Q01,  100,000 shares were  repurchased  under this
authorization,  at an average cost of $34.49 per share.  In March 2000,  the BOD
authorized  the  repurchase and  cancellation  of up to 5% of the  Corporation's
outstanding  shares,  not to exceed  approximately  3.5 million  shares,  and in
October  2000,  the  BOD  authorized  the  repurchase  and  cancellation  of  an
additional  3.2  million  shares.   Approximately   3.4  million  shares  remain
authorized  to  repurchase  under these  authorizations.  None were  repurchased
during 1Q01.  The  repurchase  of shares will be based on market  opportunities,
capital levels, growth prospects, and other investment opportunities.

The adequacy of the Corporation's  capital is regularly  reviewed to ensure that
sufficient  capital  is  available  for  current  and  future  needs  and  is in
compliance  with  regulatory  guidelines.  The  assessment  of  overall  capital
adequacy  depends on a variety of factors,  including asset quality,  liquidity,
stability of earnings,  changing  competitive  forces,  economic  conditions  in
markets served and strength of management. The capital ratios of the Corporation
and its banking  affiliates  are greater than  minimums  required by  regulatory
guidelines. The Corporation's capital ratios are summarized in Table 9.

Subsequent Events

A continuing  strategic  objective of the Corporation has been to streamline and
simplify the  Corporation.  This has included review of the branch  distribution
network (and certain  branch sales during 2000),  as well as  centralization  of
functional and operational processes. As part of this objective, the Corporation
will reduce the number of legal subsidiaries,  including  consolidating  certain
bank charters, particularly the Wisconsin bank charters, under a single national
bank  charter.  It is  anticipated  that this plan will be completed  during the
second quarter of 2001.

On April 25, 2001,  the BOD declared a $0.31 per share  dividend  payable on May
15, 2001, to shareholders of record as of May 1, 2001.
