1.   Basis of Presentation

     The accompanying consolidated statements of income and the consolidated
     statements of comprehensive income for the three and the nine months ended
     September 30, 2001 and 2000, the consolidated statements of cash flow for
     the nine months ended September 30, 2001 and 2000, and the consolidated
     statements of condition as of September 30, 2001 and December 31, 2000
     include the accounts and transactions of the Company and its five
     wholly-owned subsidiaries, Mahaska State Bank, Central Valley Bank, Pella
     State Bank, Midwest Federal Savings and Loan, and MIC Financial, Inc. All
     material intercompany balances and transactions have been eliminated in
     consolidation.

     The accompanying consolidated financial statements have been prepared by
     the Company pursuant to the rules and regulations of the Securities and
     Exchange Commission. Certain information and footnote disclosures normally
     included in financial statements prepared in accordance with generally
     accepted accounting principles have been condensed or omitted pursuant to
     such rules and regulations. Although management believes that the
     disclosures are adequate to make the information presented not misleading,
     it is suggested that these interim consolidated financial statements be
     read in conjunction with the Company's most recent audited financial
     statements and notes thereto. In the opinion of management, the
     accompanying consolidated financial statements contain all adjustments
     (consisting of only normal recurring accruals) necessary to present fairly
     the financial position as of September 30, 2001, and the results of
     operations for the three months and nine months ended September 30, 2001
     and 2000, and cash flows for the nine months ended September 30, 2001 and
     2000.

     The results for the three months and the nine months ended September 30,
     2001 may not be indicative of results for the year ending December 31,
     2001, or for any other period.

2.   Consolidated Statements of Cash Flows

     In the consolidated statements of cash flows, cash and cash equivalents
     include cash and due from banks, interest-bearing deposits with banks, and
     federal funds sold.

3.   Income Taxes

     Federal income tax expense for the three months and the nine months ended
     September 30, 2001 and 2000 was computed using the consolidated effective
     federal tax rate. The Company also recognized income tax expense pertaining
     to state franchise taxes payable individually by the subsidiary banks.

4.   Earnings Per Common Share

     Basic earnings per common share computations are based on the weighted
     average number of shares of common stock actually outstanding during the
     period. The weighted average number of shares for the three-month periods
     ended September 30, 2001 and 2000 was 3,965,326 and 3,939,314,
     respectively. The weighted average number of shares outstanding for the
     nine-month periods ended September 30, 2001 and 2000 was 3,963,377 and
     4,090,055, respectively. Diluted earnings per share amounts are computed by
     dividing net income by the weighted average number of shares and all
     dilutive potential shares outstanding during the period. The computation of
     diluted earnings per share used a weighted average number of shares
     outstanding of 4,009,252 and 3,940,773 for the three months ended September
     30, 2001 and 2000, respectively, and 3,996,971 and 4,095,766 for the nine
     months ended September 30, 2001 and 2000, respectively.

5.   Impact of New Financial Accounting Standards

     Statement of Financial Accounting Standards (SFAS) No. 133, "Accounting for
     Derivative Instruments and Hedging Activities," and SFAS No. 138,
     "Accounting for Certain Derivative Instruments and Certain Hedging
     Activities - An Amendment to FASB Statement No. 133," were adopted by the
     Company beginning January 1, 2001. The adoption of the standards did not
     have a material effect on the Company's consolidated financial statements.

     SFAS No. 140, "Accounting for Transfers and Servicing of Financial Assets
     and Extinguishment of Liabilities (a replacement of FASB Statement No.
     125)," was issued in September 2000 and was adopted by the Company
     beginning April 1, 2001. The statement revises the standards for accounting
     for securitizations and other transfers of financial assets and collateral
     and requires certain disclosures, but it carries over most of the
     provisions of Statement No. 125 without reconsideration. The statement is
     effective for transfers and servicing of financial assets and
     extinguishments of liabilities occurring after March 31, 2001. The adoption
     of the standard did not have a significant impact on the financial
     condition or results of operation of the Company.

     In July 2001, the FASB issued Statement No. 141, "Business Combinations,"
     and Statement No. 142, "Goodwill and Other Intangible Assets." Statement
     141 requires that the purchase method of accounting be used for all
     business combinations initiated after June 30, 2001 as well as all purchase
     method business combinations completed after June 30, 2001. Statement 142
     will require that goodwill and intangible assets with indefinite useful
     lives no longer be amortized, but instead tested for impairment at least
     annually in accordance with the provisions of Statement 142. Statement 142
     will also require that intangible assets with estimable useful lives be
     amortized over their respective estimated useful lives to their estimated
     residual values, and reviewed for impairment in accordance with SFAS
     Statement No. 121, "Accounting for the Impairment of Long-Lived Assets and
     for Long-Lived Assets to Be Disposed Of."

     The Company is required to adopt the provisions of Statement 141
     immediately, and Statement 142 effective January 1, 2002. Goodwill and
     intangible assets acquired in business combinations completed before July
     1, 2001 will continue to be amortized and tested for impairment in
     accordance with the appropriate pre-Statement 142 accounting requirements
     prior to the adoption of Statement 142.

     The expected amount of goodwill on January 1, 2002, is approximately
     $9,351,000 and the expected amount of other intangible assets as of that
     date is $1,324,000. We are currently evaluating the additional requirements
     of SFAS 141 and 142 to determine their potential impact on our consolidated
     financial statements.

6.   Use of Estimates in the Preparation of Financial Statements

     The preparation of financial statements in conformity with generally
     accepted accounting principles requires management to make estimates and
     assumptions that affect the reported amounts of assets and liabilities and
     disclosure of contingent assets and liabilities at the date of the
     financial statements and the reported amounts of revenues and expenses
     during the reported period. Actual results could differ from those
     estimates. A significant estimate that is particularly sensitive to change
     is the allowance for loan losses.

7.   Sale of MIC Financial, Inc.

     On April 23, 1999, the Company announced that it had elected to seek a
     buyer for MIC Financial, Inc. ("MIC Financial"), its wholly-owned
     commercial finance subsidiary. A

                                       7

<PAGE>

     satisfactory agreement could not be reached with any potential buyers, so
     the decision was made to sell groups of leases and assets. As of September
     30, 2001, MIC Financial's loan and lease portfolio totaled $1,146,000, less
     than 1 percent of the Company's total loans as of that date. Management is
     in the process of collecting the remaining assets of MIC Financial and it
     is expected that the entity will ultimately be liquidated.

PART I -- Item 2. Management's Discussion and Analysis of Financial Condition
and Results of Operations.

                        QUARTER ENDED SEPTEMBER 30, 2001

The Company recorded net income of $1,087,000 for the quarter ended September
30, 2001, compared with net income of $927,000 for the quarter ended September
30, 2000, a 17 percent increase totaling $160,000. Basic and diluted earnings
per share increased $.03 to $.27 for the third quarter of 2001 compared with
$.24 in the third quarter of 2000. Weighted average shares outstanding were
3,965,326 and 3,939,314 for the third quarter of 2001 and 2000, respectively.
The Company's return on average assets for the quarter ended September 30, 2001
was .80 percent compared with a return of .74 percent for the quarter ended
September 30, 2000. The Company's return on average shareholders' equity was
8.44 percent for the three months ended September 30, 2001 versus 7.64 percent
for the three months ended September 30, 2000.

RESULTS OF OPERATIONS

Net Interest Income

Net interest income is computed by subtracting total interest expense from total
interest income. Fluctuations in net interest income can result from the changes
in the volumes of assets and liabilities as well as changes in interest rates.
Interest rates moved up throughout the year 2000. In order to retain and attract
deposits, the Company was forced to pay higher rates that caused the cost of
funds to increase throughout the year 2000. Through the first nine months of
2001, the Federal Reserve reduced interest rates. The Company's net interest
income for the quarter ended September 30, 2001 increased $577,000 to $4,869,000
from $4,292,000 for the three months ended September 30, 2000. Total interest
income was $424,000 or 4 percent higher in the third quarter of 2001 compared
with the same period in 2000. The Company's total interest expense for the third
quarter of 2001 decreased $153,000 or 3 percent compared with the same period in
2000. The Company's net interest margin on a federal tax-equivalent basis for
the third quarter of 2001 increased to 3.92 percent from 3.77 percent in the
third quarter of 2000. Net interest margin is a measure of the net return on
interest-earning assets and is computed by dividing annualized net interest
income by the average of total interest-earning assets for the period. The
Company's overall yield on earning assets was 8.20 percent for the third quarter
of 2001 compared to 8.55 percent for the third quarter of 2000. The rate on
interest-bearing liabilities decreased in the third quarter of 2001 to 4.71
percent compared to 5.25 percent for the third quarter of 2000.

Interest income and fees on loans decreased $325,000 or 5 percent in the third
---------------------------------
quarter of 2001 compared to the same period in 2000, mainly due to lower
interest rates on loans. During the third quarter of 2001, the Company reversed
interest of approximately $42,000 on loans that were placed on a nonaccrual
status. The average yield on loans decreased to 7.82 percent for the third
quarter of 2001, compared to 8.43 percent in the third quarter of 2000. The
yield on the Company's loan portfolio is affected by the amount of nonaccrual
loans, the mix of the portfolio (real estate loans generally have a lower
overall yield than commercial and agricultural loans), the effects of
competition and the interest rate environment on the amounts and volumes of new
loan originations, and the mix

                                       9

<PAGE>

of variable rate versus fixed rate loans in the Company's portfolio. The recent
actions by the Federal Reserve to lower interest rates were not beneficial to
the Company in the current period and will affect future periods as variable
rate loans tied to prime have been adjusted downward and will produce less
interest income. Competition for loans in the market areas served by the Company
remains strong as customers seek to refinance loans to obtain lower interest
rates. Average loans outstanding increased to $318,334,000 for the third quarter
of 2001 compared with $311,139,000 for the third quarter of 2000, an increase of
$7,195,000 or 2 percent.

Interest and discount income on loan pool participations increased $1,125,000 or
--------------------------------------------------------
66 percent in the third quarter of 2001 compared with 2000, mainly due to higher
collections associated with an increase in the volume of loan pool
participations. Interest income and discount claimed on the loan pool
participations for the three months ended September 30, 2001 was $2,829,000
compared with $1,704,000 claimed in the third quarter of 2000. The yield on loan
pool participations was 11.3 percent for the third quarter of 2001 compared with
11.7 percent for the quarter ended September 30, 2000. The average loan pool
participation balance was $41,872,000 or 72 percent higher in the third quarter
of 2001 than in 2000 as a result of pool purchases in the fourth quarter of 2000
and during the second and third quarters of 2001. Newly purchased loan pools
typically do not produce income for a period of up to 120 days from date of
purchase, which significantly impacts the overall yield on pools. These loan
pool participations are pools of performing, nonperforming, and distressed loans
that the Company has purchased at a discount from the aggregate outstanding
principal amount of the underlying loans. Income is derived from this investment
in the form of interest collected and the repayment of the principal in excess
of the purchase cost which is herein referred to as "discount recovery." The
Company recognizes interest income and discount recovery on its loan pool
participations on a cash basis. The loan pool participations have traditionally
been a high-yield activity for the Company, but this yield has fluctuated from
period to period based on the amount of cash collection, discount recovery, and
net collection expenses of the servicer in any given period. The income and
yield on loan pool participations may vary in future periods due to the volume
and discount rate on loan pools purchased.

Interest income on investment securities decreased $407,000 or 27 percent in the
----------------------------------------
quarter ended September 30, 2001, compared with the quarter ended September 30,
2000 due to lower volumes of investment securities and also due to decreased
interest rates. Interest income on investment securities totaled $1,101,000 for
the third quarter of 2001 compared with $1,508,000 in 2000. The average balance
of investments in 2001 was $73,749,000, a decrease from $90,993,000 in the third
quarter of 2000. The yield on the Company's investment portfolio in the third
quarter of 2001 decreased to 6.36 percent from 7.02 percent in the comparable
period of 2000.

Interest expense on deposits decreased $88,000 in the third quarter of 2001
----------------------------
compared with 2000. This decrease was mainly attributable to the reduction in
interest rates paid to depositors. Interest expense attributable to increased
volumes of savings and time deposits somewhat offset the lower interest rates.
Average interest-bearing deposits for the third quarter of 2001 increased
$24,376,000 or 7 percent from the same period in 2000. The weighted average rate
paid on interest-bearing deposits was 4.28 percent in the third quarter of 2001
compared with 4.72 percent in the third quarter of 2000. Reductions in interest

                                       10

<PAGE>

rates should benefit the Company in future periods as rates paid on deposits
move downward. Competition for deposits remains intense in the markets served by
the Company. The full benefit of the downward movement in deposit rates may not
be realized if the competitive environment forces the Company to pay
above-market rates to attract or retain deposits.

Interest expense on borrowed funds decreased a total of $65,000 in the third
----------------------------------
quarter of 2001 compared with 2000. Interest expense on Federal Home Loan Bank
advances was $151,000 higher in the third quarter of 2001 reflecting the
Company's greater utilization of this alternative funding method. The
weighted-average rate paid on Federal Home Loan Bank advances decreased to 6.30
percent in the third quarter of 2001 compared with 6.71 percent in the third
quarter of 2000 due to reductions in the interest rate environment. The
continued reduction in rates should benefit the Company as Federal Home Loan
Bank advances reprice. Interest expense on notes payable decreased $159,000 in
the third quarter of 2001 compared with 2000 reflecting lower average borrowings
on the Company's commercial bank line of credit and decreased interest rates.
The average rate paid during the third quarter of 2001 was 6.14 percent compared
with 9.29 percent in the quarter ended September 30, 2000. The Company's notes
payable line is variable with the national prime rate and reductions in this
rate will lower the amount of interest expense incurred in the future. Interest
expense on federal funds purchased decreased $57,000 in the third quarter of
2001 compared with 2000 reflecting both lower interest rates and reduced
borrowing during the period. Interest rates on federal funds purchased averaged
4.01 percent in the quarter ended September 30, 2001 compared with 6.92 percent
in the third quarter of 2000.

Provision for Loan Losses

The Company recorded a provision for loan losses of $1,006,000 in the third
quarter of 2001 compared with $319,000 in the third quarter of 2000. The
$687,000 increase in the third quarter of 2001 was primarily the result of
deterioration and the subsequent charge-off of $1,000,000 in one agricultural
line of credit. Management determines an appropriate provision based on its
evaluation of the adequacy of the allowance for loan losses in relationship to a
continuing review of problem loans, the current economic conditions, actual loss
experience and industry trends. Management believes that the allowance for loan
losses is adequate based on the inherent risk in the portfolio as of September
30, 2001; however, continued growth in the loan portfolio and the uncertainty of
the general economy require that management continue to evaluate the adequacy of
the allowance for loan losses and make additional provisions in future periods
as deemed necessary.

Noninterest Income

Noninterest income results from the charges and fees collected by the Company
from its customers for various services performed, data processing income
received from nonaffiliated banks, and miscellaneous other income and gains (or
losses) from the sale of investment securities held in the available for sale
category. Total noninterest income was $732,000 or 118 percent greater in the
third quarter of 2001 compared with 2000. The largest part of the increase was
attributable to gains recognized during the 2001 quarter on the sale of
investment securities to fund loan pool purchases. Approximately $19,067,000 of
investment securities was sold with a gain of $579,000 realized. Most of the

                                       11

<PAGE>

remaining increase was due to higher service charge income and other operating
income.

Noninterest Expense

Total noninterest expense for the quarter ended September 30, 2001 increased
$296,000 compared to noninterest expense for the third quarter of 2000.
Noninterest expense includes all the costs incurred to operate the Company
except for interest expense, the provision for loan losses and income tax
expense. Salaries and benefits expense for the third quarter of 2001 increased
$101,000 or 6 percent from 2000 as a result of higher salary and benefit costs
in the current period. As of September 30, 2001, the Company had 165 full-time
equivalent employees, which is comparable with September 30, 2000. Net occupancy
and equipment expenses for the third quarter of 2001 increased $83,000 or 18
percent in comparison to 2000 with much of the increase due to additional
facilities at Pella State Bank and also due to utility costs. Professional fees
for the three months ended September 30, 2001 increased by $50,000 compared to
2000 as the Company utilized an outside firm to conduct a business process
analysis and profit improvement study. This project was undertaken to identify
opportunities to improve efficiency and reduce expenses in future periods and to
increase revenues. The goal is to enhance the overall profitability of the
Company and to increase returns to shareholders going forward. Findings and
recommendations from the study will be implemented whenever feasible. Other
operating expense increased by $81,000 or 11 percent in the third quarter of
2001 compared with the recorded amount for the three months ended September 30,
2000 mainly due to the write-off of the remaining leasehold improvements of the
relocated grocery store branch of Central Valley Bank.

Income Tax Expense

The Company incurred income tax expense of $582,000 for the three months ended
September 30, 2001 compared with $416,000 for the three months ended September
30, 2000. The effective income tax rate as a percent of income before taxes for
the three months ended September 30, 2001 and 2000 was 34.9 percent and 31.0
percent, respectively.

                      NINE MONTHS ENDED SEPTEMBER 30, 2001

The Company earned net income of $3,058,000 during the first nine months of 2001
compared with $3,011,000 in the first nine months of 2000. Net income was
$47,000 or 2 percent greater for the nine months ended September 30, 2001 in
comparison to 2000. Basic and diluted earnings per share were $.77 for 2001
compared with basic and diluted earnings per share of $.74 for the first nine
months of 2000. Weighted average shares outstanding in 2001 were 3,963,377 and
4,090,055 in 2000. Weighted average diluted shares outstanding were 3,996,971 in
2001 compared with 4,095,766 in 2000. The return on average assets for the first
nine months of 2001 was .78 percent in 2001 and .82 percent in 2000. Return on
average shareholders' equity was 8.08 percent for the first nine months of 2001
compared with 8.21 percent in 2000.

RESULTS OF OPERATIONS

Net Interest Income

Net interest income increased $310,000 or 2 percent in the first nine months of
2001 compared with 2000. Total interest income for the nine months ended
September 30, 2001 increased $1,273,000 or 4 percent compared with 2000 while
interest expense increased $963,000 or 6 percent in 2001 compared with 2000. The
Company's net interest margin for the first nine months of 2001 decreased to
3.78 percent from 4.00 percent in 2000. The yield on earning assets for 2001 was
8.30 percent compared with 8.59 percent in 2000. The yields on the Company's
variable-rate loans and other earning assets declined in the first nine months
of 2001 reflecting the interest rate reductions by the Federal Reserve. The rate
on interest-bearing liabilities for the first nine months of 2001 also decreased
to 4.98 percent from 5.06 percent in 2000. The average rates on certificates of
deposit increased for 2001 compared to 2000 as a result of higher rates the
Company was forced to pay throughout 2000. As certificates mature in future
periods, the rates paid on these deposits should decline depending on the
national interest rate environment and the effects of local market competition.

Interest income and fees on loans increased $373,000 or 2 percent in the first
---------------------------------
nine months of 2001 compared to 2000 mainly due to higher loan volumes. The
average yield on loans decreased to 8.09 percent in 2001 from 8.35 percent in
2000. Average loans outstanding were $314,574,000 for 2001 compared with
$298,646,000 in 2000, an increase of $15,928,000 or 5 percent.

Interest and discount income on loan pool participations increased $1,367,000 or
--------------------------------------------------------
24 percent in 2001 compared with 2000, mainly due to the higher volume of loan
pools. Interest income and discount earned on the loan pool participations for
the first nine months of 2001 was $6,979,000 compared with $5,612,000 in 2000.
The yield on loan pool participations declined to 11.3 percent in 2001 compared
with 12.5 percent in 2000. The average loan pool participation balance was
$82,248,000 in 2001 compared with $60,036,000 in 2000. The increase in average
balance of $22,212,000 or 37 percent resulted from purchases of pools in the
fourth quarter of 2000 and in the second and third quarters of 2001.

Interest income on investment securities decreased $509,000 or 11 percent in
----------------------------------------
2001 compared with 2000 primarily due to lower balances and reduced interest
rates. The interest rates on maturing securities were higher than the rates on
new securities purchased year-to-date in 2001. Interest income on investment
securities was $4,012,000 in 2001 compared with $4,521,000 in 2000. The average
balance of investments in 2001 was $86,167,000 compared with $92,211,000 in
2000. The overall yield on the Company's investment portfolio was 6.64 percent
for the first nine months of 2001 compared with 6.98 percent in 2000.

Interest expense on deposits increased $887,000 or 8 percent in the nine months
----------------------------
ended September 30, 2001 compared with 2000. This increase was mainly due to
growth and increased interest rates on certificates of deposit. The average
balance of certificates of deposit for the nine months ended September 30, 2001
was $217,381,000 compared with $190,199,000 in 2000 while the average rate paid
on certificates of deposit rose to 5.66 percent in 2001 compared with 5.45
percent in 2000. Volumes and interest rates on interest-bearing demand deposits
and savings deposits were lower in the first nine months of 2001 compared with

                                       13

<PAGE>

2000. The Company's overall rate paid on interest-bearing deposits was 4.58
percent for the first nine months of 2001 compared with 4.55 percent in 2000.

Interest expense on borrowed funds increased $76,000 or 2 percent in 2001 versus
----------------------------------
2000 mainly due to higher balances of Federal Home Loan Bank advances. Interest
expense incurred on the Federal Home Loan Bank advances increased $583,000 or 18
percent in 2001 as the average balance of advances increased $14,180,000 in
comparison with 2000. The average rate paid on Federal Home Loan Bank advances
declined somewhat in the first nine months of 2001 to 6.38 percent compared with
6.56 percent for the nine months ended September 30, 2000. Interest expense on
notes payable decreased $380,000 or 36 percent in the first nine months of 2001
reflecting both a reduction in the average amount borrowed and lower interest
rates. The average rate on notes payable was 7.23 percent for the nine months
ended September 30, 2001, compared with 8.95 percent for the first nine months
of 2000. Federal funds purchased decreased $127,000 or 72 percent in 2001 due to
lower balances and lower interest rates.

Provision for Loan Losses

The provision for loan losses recorded by the Company in the first nine months
of 2001 was $1,507,000 compared with $740,000 in 2000. The additional $767,000
provision in 2001 was deemed necessary due to a $1,000,000 charge-off of one
agricultural line of credit in the third quarter of 2001. The Company's
provision for loan losses reflects management's determination of the adequacy of
the allowance for loan losses in view of the amount of nonperforming assets,
growth in the Company's loan portfolio, net loan charge-offs, and overall
economic conditions.

Noninterest Income

Total noninterest income increased $1,472,000 or 78 percent in 2001 compared
with 2000. The largest single contribution to the increase was from the gain
recognized on the sale of investment securities, which increased $955,000 in
comparison with 2000. During the second and third quarters of 2001, investment
securities were sold and the proceeds were reinvested in loan pool
participations. Service charge income increased $225,000 or 17 percent in 2001
due to higher fees and other operating income increased $288,000 or 76 percent
in 2001 reflecting additional sales of credit life insurance and increased other
fee income.

Noninterest Expense

Noninterest expense increased $865,000 or 9 percent in the first nine months of
2001 compared with 2000. Salaries and benefits cost rose $385,000 or 8 percent
due to higher salary and benefit costs as well as an increase in the average
number of employees. The average number of full-time equivalent employees for
the first nine months of 2001 was 166 compared with an average of 159 for the
nine months ended September 30, 2000. The addition of the Pella State Bank
facility as well as the expansion of services at Midwest Federal Savings
resulted in an increase in employees and higher salaries and benefits expense.
One of the goals of the profitability enhancement study was to review staffing
levels and activities in order to maximize efficiency. It is anticipated that
the findings of this study should result in more efficient utilization of
personnel and adjusted staffing levels in future periods. Net occupancy expenses
rose $222,000

                                       14

<PAGE>

or 16 percent in 2001 due to new facilities in Pella and the Fairfield, Iowa
location of Central Valley Bank. The other major change in noninterest expense
was a $319,000 increase in professional fees primarily related to the
aforementioned profitability enhancement study. The majority of this study is
now completed with minimal additional costs projected in future periods.

Income Tax Expense

The Company incurred income tax expense of $1,585,000 for the first nine months
of 2001 compared with $1,482,000 in 2000 primarily due to higher income in 2001.
The effective income tax rate as a percentage of income before taxes was 34.1
percent in 2001 and 33.0 percent in 2000.

FINANCIAL CONDITION

Total assets as of September 30, 2001 were $528,904,000, an increase of
$13,692,000 or 3 percent from December 31, 2000.

Investment Securities

Investment securities available for sale decreased $15,020,000 from December 31,
2000 to $45,738,000 on September 30, 2001. Securities were sold to reposition
the Company's balance sheet through the purchase of loan pool participations and
to fund loan demand. Management does not plan to significantly further reduce
the level of investment securities available for sale. Investment securities
classified as held to maturity declined to $22,114,000 as of September 30, 2001,
compared with $25,921,000 on December 31, 2000, as the proceeds from maturities
were reinvested in available for sale securities.

Loans

Loan volumes increased $9,249,000 in the first nine months of 2001, with total
loans outstanding of $321,330,000 on September 30, 2001, reflecting growth of 3
percent from December 31, 2000. Loan growth during the period was 5 percent
below forecast and lower than the 12 percent growth achieved in the first nine
months of 2000 as loan demand softened. As of September 30, 2001, the Company's
loan to deposit ratio (excluding loan pool investments) was 84.5 percent
compared with a year-end 2000 loan to deposit ratio of 84.3 percent. Loans
secured by real estate (including 1 to 4 family, multi-family, commercial and
agricultural) comprised the largest category in the portfolio at approximately
68 percent of total loans. Agricultural loans were the next largest category at
approximately 15 percent of total loans and commercial loans represented
approximately 12 percent. Loans to individuals and other loans constituted
approximately 5 percent. As of September 30, 2001, real estate loans as a
percentage of total loans increased approximately 2 percent and loans to
individuals decreased approximately 2 percent in comparison with the percentage
distribution by loan category as of December 31, 2000.

Loan Pool Participations

As of September 30, 2001, the Company had loan pool participations of
$101,438,000, an increase of $26,683,000 or 36 percent from the December 31,
2000 balance of $74,755,000. The increase in the loan pool participations
reflects the volume of pools purchased in 2001, primarily in the second and
third quarters. During the second quarter of 2001, the Company purchased
$28,312,000 in loan pools. Pool purchases totaled $48,790,000 in the third
quarter. Some of the pools purchased in the third quarter were acquired with the
intent to resell them. Loans having a cost of $25,870,000 were sold during the
third quarter of 2001. The loan pool investment balance shown as an asset on the
Company's Statement of Condition represents the discounted purchase cost of the
loan pool participations. The average loan pool participation balance of
$99,733,000 for the three months ended September 30, 2001 was $41,872,000 or 72
percent higher than the average balance of $57,861,000 for the third quarter of
2000. For the first nine months of 2001, the Company's average loan pool
participation balance was $82,248,000 compared with $60,036,000 in 2000.

Deposits

Total deposits as of September 30, 2001 were $380,132,000 compared with
$370,144,000 as of December 31, 2000. Deposits grew $9,988,000 or 3 percent in
the first nine months of 2001. Certificates of deposit are the largest category
of deposits at September 30, 2001 representing approximately 57 percent of total
deposits. Most of the growth in deposits during the period was in savings/money
funds and in certificates of deposit. Demand deposits decreased during the first
nine months of the year. Total deposits declined slightly during the third
quarter of 2001.

Borrowed Funds/Notes Payable

The Company had $1,570,000 Federal Funds purchased on September 30, 2001. There
was $2,345,000 in Federal Funds purchased on December 31, 2000. During the first
nine months of 2001, the Company had an average balance of Federal Funds
purchased of $1,517,000. Advances from the Federal Home Loan Bank totaled
$78,643,000 as of September 30, 2001 compared with $75,050,000 as of December
31, 2000. Most of the additional advances were utilized to purchase loan pool
participations. Notes payable declined to $11,800,000 on September 30, 2001 from
$13,200,000 on December 31, 2000 as a result of principal payments. Effective
August 24, 2001, the Company amended its credit agreement whereby the interest
rate on its notes payable was reduced to .80 percent below the prime rate and
the maturity of the revolving portion of the credit line was extended to June
30, 2002.

Nonperforming Assets

The Company's nonperforming assets totaled $5,250,000 (1.63 percent of total
loans) as of September 30, 2001, compared to $3,523,000 (1.13 percent of total
loans) as of December 31, 2000. All nonperforming asset totals and related
ratios exclude the loan pool participations. The following table presents the
categories of nonperforming assets as of September 30, 2001 compared with
December 31, 2000:

From December 31, 2000 to September 30, 2001, nonaccrual loans increased
$1,976,000 primarily as the result of loans made to investors in a large
cattle-feeding operation being placed on a nonaccrual status during the third
quarter at the direction of the Federal Deposit Insurance Corporation. It is
anticipated that most of these loans will be returned to performing status once
a satisfactory repayment plan is completed. During the third quarter of 2001,
$1,000,000 of a large agricultural line that had been on a nonaccrual status was
charged-off. Loans ninety days past due increased $169,000. Other real estate
owned decreased by $418,000 as property held in this category was sold. The
Company's allowance for loan losses as of September 30, 2001 was $3,262,000,
which was 1.02 percent of total loans as of that date. This compares with an
allowance for loan losses of $2,933,000 as of December 31, 2000, which was .94
percent of total loans. As of September 30, 2001, the allowance for loan losses
was 64.00 percent of nonperforming loans compared with 99.35 percent as of
December 31, 2000. Based on the inherent risk in the loan portfolio, management
believes that as of September 30, 2001, the allowance for loan losses is
adequate. For the three months ended September 30, 2001, the Company's net loan
charge-offs were $1,036,000 or 1.29 percent of average loans outstanding on an
annualized basis compared with net charge-offs of $610,000 during the quarter
ended September 30, 2000. For the first nine months of 2001, the Company had net
loan charge-offs totaling $1,178,000 or .50 percent of average loans outstanding
annualized. This compares with net charge-offs of $1,421,000 in the first nine
months of 2000. During the first nine months of 2000, MIC Financial charged off
$620,000 compared with a net charge-off of $10,000 through September 30, 2001.

Capital Resources

Total shareholders' equity was 9.6 percent of total assets as of September 30,
2001 and on December 31, 2000. As of September 30, 2001, the Company's Tier 1
Capital Ratio was 9.9 percent of risk-weighted assets and was 10.6 percent as of
December 31, 2000, compared to a 4.0 percent regulatory requirement. Risk-based
capital guidelines require the classification of assets and some
off-balance-sheet items in terms of credit-risk exposure and the measuring of
capital as a percentage of the risk-adjusted asset totals. Tier 1 Capital is the
Company's total common shareholders' equity reduced by goodwill. Management
believes that, as of September 30, 2001, the Company and its subsidiary banks
meet all capital adequacy requirements to which they are subject. As of that
date, all the bank subsidiaries were "well capitalized" under regulatory prompt
corrective action provisions. During the first nine months of 2001, the Company
issued 33,092 shares of stock upon the exercise of stock options previously
granted to employees.

As a result of the uncertainty in the financial markets following the events of
September 11, 2001, the Company's Board of Directors approved a stock repurchase
plan that was announced September 14, 2001. The Board authorized up to
$4,000,000 not to exceed 10 percent of the shares outstanding to be repurchased
in the open market until December 31, 2001. On September 18, 2001, the Company
repurchased 48,000 shares at a cost of $547,200.

Liquidity

Liquidity management involves meeting the cash flow requirements of depositors
and borrowers. The Company conducts liquidity management on both a daily and
long-term basis; and it adjusts its investments in liquid assets based on
expected loan demand, projected loan maturities and payments, estimated cash
flows from the loan pool participations, expected deposit flows, yields
available on interest-bearing deposits, and the objectives of its
asset/liability management program. The Company had liquid assets (cash and cash
equivalents) of $12,385,000 as of September 30, 2001, compared with $15,517,000
as of December 31, 2000. Most of the decrease during the period was in
interest-bearing deposits in banks and in federal funds sold. Investment
securities classified as available for sale could be sold to meet liquidity
needs if necessary. Additionally, the bank subsidiaries maintain lines of credit
with correspondent banks and the Federal Home Loan Bank that would allow them to
borrow federal funds on a short-term basis if necessary. The Company also
maintains a line of credit with a major commercial bank that provides liquidity
for the purchase of loan pool participations and other corporate needs.
Management believes that the Company has sufficient liquidity as of September
30, 2001 to meet the needs of borrowers and depositors.

As of September 30, 2001, the Company had no federal funds sold and $1,570,000
federal funds purchased compared with $1,155,000 sold and $2,345,000 purchased
as of December 31, 2000. The Company's liquidity needs are usually highest in
the second and third quarters of each year due to seasonal loan demand and
minimal deposit growth in the first nine months of the year. Federal funds are
purchased on a short-term basis to meet this liquidity need.

Market Risk Management

Market risk is the risk of earnings volatility that results from adverse changes
in interest rates and market prices. The Company's market risk is primarily
comprised of interest rate risk arising from its core banking activities of
lending and deposit taking. Interest rate risk is the risk that changes in
market interest rates may adversely affect the Company's net interest income.
Management continually develops and applies strategies to mitigate this risk.
The Company has not experienced any material changes to its market risk position
since December 31, 2000, from that disclosed in the Company's 2000 Form 10-K
Annual Report. Management does not believe that the Company's primary market
risk exposures and how those exposures were managed in the first nine months of
2001 changed when compared to 2000.

The Company uses a third-party computer software simulation modeling program to
measure its exposure to potential interest rate changes. For various assumed
hypothetical changes in market interest rates, numerous other assumptions are
made such as prepayment speeds on loans and securities backed by mortgages, the
slope of the Treasury yield curve, the rates and volumes of the Company's

                                       18

deposits and the rates and volumes of the Company's loans. This analysis
measures the estimated change in net interest income in the event of
hypothetical changes in interest rates. This analysis of the Company's interest
rate risk was presented in the Form 10-K filed by the Company for the year ended
December 31, 2000.

Commitments and Contingencies

In the ordinary course of business, the Company is engaged in various issues
involving litigation. Management believes that none of this litigation is
material to the Company's results of operations.
