1.       Basis of Presentation

         The accompanying consolidated statements of income, the consolidated
         statements of comprehensive income, and the consolidated statements of
         cash flow for the three months ended March 31, 2002 and 2001 and the
         consolidated statements of condition as of December 31, 2001 and March
         31, 2002 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 March 31,
         2002, and the results of operations for the three months ended March
         31, 2002 and 2001, and cash flows for the three months ended March 31,
         2002 and 2001.

         The results for the three months ended March 31, 2002 may not be
         indicative of results for the year ending December 31, 2002, 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 ended March 31, 2002
         and 2001 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 March 31, 2002 and 2001 was 3,871,038 and 3,953,471,
         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 3,937,121 and 3,980,934 for the three
         months ended March 31, 2002 and 2001, respectively.

5.       Effect 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

<PAGE>

         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. 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 SFAS
         No. 140 did not have a material impact on the financial condition or
         results of operation of the Company.

         SFAS No. 141, "Business Combinations," was adopted by the Company on
         July 1, 2001. The statement requires that the purchase method of
         accounting be used for all business combinations completed after June
         30, 2001. The adoption of this statement did not have a material effect
         on the Company's financial statements.

         SFAS No. 142, "Goodwill and Other Intangible Assets," was adopted by
         the Company on January 1, 2002. Statement 142 requires that goodwill
         and intangible assets with indefinite useful lives no longer be
         amortized, but instead be tested for impairment at least annually in
         accordance with the provisions of Statement 142. Statement 142 also
         requires 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
         adoption of SFAS No. 142 reduced the Company's goodwill amortization
         expense $63,000 beginning in the first quarter of 2002 since the
         goodwill attributable to the acquisition of Midwest Federal Savings is
         no longer being amortized. As of January 1, 2002, the goodwill
         attributable to the Midwest Federal Savings acquisition totaled
         $5,667,000. Goodwill in the amount of $3,684,000 as of January 1, 2002
         continues to be amortized under SFAS Statement No. 72, "Accounting for
         Certain Acquisitions of Banking or Thrift Institutions." Under the
         provisions of this statement, the goodwill relating to the acquisitions
         of the United Federal Savings branches in 1994 and the acquisition of
         the Boatmen's Bank branch in 1996 is defined as "unidentifiable
         intangible assets" and must continue to be amortized.

         The table below reconciles the reported earnings for the three months
         ended March 31, 2001 to "adjusted earnings," which exclude goodwill
         amortization.

         Effective January 1, 2002 goodwill will be assessed at least annually
         for impairment by applying a fair-value-based test using discounted
         cash flows. The Company will complete its initial goodwill impairment
         assessment in the second quarter and does not anticipate any
         transitional impairment charge.

         SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived
         Assets," was issued in August 2001 and was adopted by the Company on
         January 1, 2002. SFAS No. 72 addresses financial accounting and
         reporting for the impairment or disposal of long-lived assets. The
         adoption of SFAS 144 did not have a material effect on the results of
         operations or financial condition of the Company.

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 satisfactory agreement could not be
         reached with any potential buyers, so the decision was made to sell
         groups of leases and assets. As of March 31, 2002, MIC Financial's loan
         and lease portfolio totaled $968,000, less than 1 percent of the
         Company's total loans as of that date. Management continues to evaluate
         options on the remaining assets of MIC Financial.

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

                          QUARTER ENDED MARCH 31, 2002

The Company recorded net income of $1,417,000 for the quarter ended March 31,
2002, compared with net income of $992,000 for the quarter ended March 31, 2001,
an increase of $425,000 or 43 percent. The increase in net income was primarily
due to improved net interest income. Basic earnings per share for the first
quarter of 2002 were $.37 versus $.25 for the first quarter of 2001. Diluted
earnings per share were $.36 in 2002 and $.25 for the first quarter of 2001.
Actual weighted average shares outstanding were 3,871,038 and 3,953,471 for the
first quarter of 2002 and 2001, respectively. The Company's return on average
assets for the quarter ended March 31, 2002 was 1.07 percent compared with a
return of .78 percent for the quarter ended March 31, 2001. The Company's return
on average equity was 11.21 percent for the three months ended March 31, 2002
versus 8.06 percent for the three months ended March 31, 2001.

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.
Market interest rates on a national and local level moved downward throughout
the year 2001. Interest rates remained relatively constant during the first
quarter of 2002. The Company's net interest income for the quarter ended March
31, 2002 increased $853,000 or 20 percent to $5,170,000 from $4,317,000 for the
three months ended March 31, 2001. Total interest income was $369,000 or 4
percent lower in the first quarter of 2002 compared with the same period in 2001
primarily due to reduction in interest rates. The Company's total interest
expense for the first quarter of 2002 decreased $1,222,000 or 22 percent
compared with the same period in 2001 due to the lower interest rate
environment. The Company's net interest margin on a federal tax-equivalent basis
for the first quarter of 2002 increased to 4.21 percent from 3.73 percent in the
first quarter of 2001. 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 7.76 percent for the first quarter
of 2002 compared with 8.51 percent for the first quarter of 2001. The rate on
interest-bearing liabilities decreased in the first quarter of 2002 to 3.91
percent compared to 5.25 percent for the first quarter of 2001.

Interest income and fees on loans decreased $611,000 or 9 percent in the first
---------------------------------
quarter of 2002 compared to the same period in 2001, mainly due to lower
interest rates. The average yield on loans decreased to 7.50 percent for the
first quarter of 2002, compared to 8.42 percent in the first quarter of 2001.
The yield on the Company's loan portfolio is affected by the amount of
nonaccrual loans (which do not earn interest income), 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

<PAGE>

amounts and volumes of new loan originations, and the mix of variable rate
versus fixed rate loans in the Company's portfolio. The lower interest rates
were not beneficial to the Company as variable rate loans tied to prime were
adjusted downward and produced less interest income. Renewing fixed-rate loans
have been rewritten at lower rates reflecting the market interest rate
environment. Loan demand by customers in the market areas served by the Company
has become "soft" as general economic conditions have weakened and potential
borrowers are less willing to increase their debt load. Average loans
outstanding were $316,549,000 in 2002 compared with $311,553,000 for the first
quarter of 2001, an increase of $4,996,000 or 2 percent.

Interest and discount income on loan pool participations increased $706,000 or
--------------------------------------------------------
35 percent in the first quarter of 2002 compared with 2001, as a result of the
greater volume of loan pool participations. Interest income and discount
collected on the loan pool participations for the three months ended March 31,
2002 was $2,697,000 compared with $1,991,000 collected in the first quarter of
2001. The yield on loan pool participations was 10.3 percent for the first
quarter of 2002 compared with 11.4 percent for the quarter ended March 31, 2001.
The average loan pool participation investment balance was $35,274,000 or 50
percent higher in the first quarter of 2002 than in 2001 as a result of pool
purchases in the second, third, and fourth 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 and distressed and
nonperforming 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 $401,000 or 28 percent in the
----------------------------------------
quarter ended March 31, 2002, compared with the quarter ended March 31, 2001 due
to decreased volume in the portfolio and also due to the decreased interest
rates. Interest income on investment securities totaled $1,018,000 for the first
quarter of 2002 compared with $1,419,000 in 2001. The average balance of
investments in 2002 was $75,247,000, down from $88,492,000 in the first quarter
of 2001. The yield on the Company's investment portfolio in the first quarter of
2002 decreased to 5.89 percent from 6.94 percent in the comparable period of
2001.

Interest expense on deposits decreased $1,166,000 in the first quarter of 2002
----------------------------
compared with 2001 mainly due to the lowered national and local market interest
rate environment. Average interest-bearing deposits for the first quarter of
2002 increased $7,075,000 or 2 percent from the same period in 2001.
Interest-bearing demand deposits and savings accounts increased in 2002 while
average certificates of deposit decreased. The weighted average rate paid on
interest-bearing deposits was 3.42 percent in the first quarter of 2002 compared
with 4.85 percent in the

<PAGE>

first quarter of 2001. The full benefit of lower market deposit rates may not be
realized if the competitive environment forces the Company to pay above-market
rates to attract or retain deposits in future periods.

Interest expense on borrowed funds decreased $56,000 in the first quarter of
----------------------------------
2002 compared with 2001. Interest expense on Federal Home Loan Bank advances was
$112,000 higher in the first quarter of 2002 reflecting the Company's greater
utilization of this alternative funding method. Interest expense on notes
payable decreased $173,000 in the first quarter of 2002 compared with 2001
reflecting lower average borrowings on the Company's commercial bank line of
credit and decreased interest rates. The Company's notes payable line is
variable with the national prime rate and any changes in this rate will affect
the amount of interest expense incurred in future periods.

Provision for Loan Losses

The Company recorded a provision for loan losses of $260,000 in the first
quarter of 2002 compared with $147,000 in the first quarter of 2001. 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 March 31, 2002, however, 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.

Other Income

Other 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, miscellaneous other income and gains (or losses) from the
sale of investment securities held in the available for sale category. Total
other income was $130,000 or 17 percent greater in the first quarter of 2002
compared with 2001. Most of the increase was due to higher service charge income
and origination fees for loans sold on the secondary market.

Other Expense

Total other noninterest expense for the quarter ended March 31, 2002 increased
$149,000 compared to noninterest expense for the first quarter of 2001. Other
expense includes all the costs incurred to operate the Company except for
interest expense, the loan loss provision and income taxes. Salaries and
benefits expense for the first quarter of 2002 increased $76,000 or 5 percent
from 2001 as a result of increased salary levels and health insurance costs.
Other operating expense increased by $169,000 in the first quarter of 2002
compared with the three months ended March 31, 2001 due to the write-down to
market value of a commercial property held in other real estate. Goodwill and
other intangible asset amortization decreased $79,000 in the first quarter of
2002 as a result of the adoption of FASB Statement No. 142, which permitted the
discontinuation of amortization of goodwill effective January 1, 2002. The
Company does continue to

<PAGE>

amortize core deposit intangibles and Statement 72 unidentifiable intangible
assets.

Income Tax Expense

The Company incurred income tax expense of $807,000 for the three months ended
March 31, 2002 compared with $511,000 for the three months ended March 31, 2001.
The increased tax expense for the March 2002 quarter was mainly due to higher
overall taxable income compared to the same period in the prior year. The
effective income tax rate as a percent of income before taxes for the three
months ended March 31, 2002 and 2001 was 36.3 percent and 34.0 percent,
respectively.

FINANCIAL CONDITION

Total assets as of March 31, 2002 were $548,881,000, an increase of $3,086,000
or less than 1 percent from December 31, 2001. As of March 31, 2002, the Company
had $7,245,000 in federal funds sold and no federal funds purchased compared
with $10,650,000 purchased as of December 31, 2001. 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.

Investment Securities

Investment securities available for sale totaled $60,723,000 as of March 31,
2002. This is an increase of $10,517,000 from December 31, 2001 as securities
were purchased for the portfolio. Investment securities classified as held to
maturity declined to $20,535,000 as of March 31, 2002, compared with $21,332,000
on December 31, 2001, as the proceeds from maturities were reinvested in
available for sale securities.

Loans

Loan volumes declined in the first quarter of 2002 to $314,309,000 on March 31,
2002. The $8,372,000 decrease from December 31, 2001 was, in part, due to the
payoff of a large commercial real estate line, continued refinancing of
residential real estate loans into long-term fixed rate secondary market loans,
and a general weakening in economic conditions in the markets served by the
Company. As of March 31, 2002, the Company's loan to deposit ratio (excluding
loan pool investments) was 81.0 percent compared with a year-end 2001 loan to
deposit ratio of 85.2 percent. The decrease in the loan to deposit ratio is
attributable to the decline in loan volume and the increase in deposits since
December 31, 2001. As of March 31, 2002, loans secured by real estate (including
1 to 4 family, multi-family, commercial and agricultural) comprised the largest
category in the portfolio at approximately 72 percent of total loans.
Agricultural loans and commercial loans were each approximately 12 percent of
total loans. Loans to individuals and other loans constituted approximately 4
percent.

<PAGE>

Loan Pool Participations

As of March 31, 2002, the Company had loan pool participations of $108,530,000,
a decrease of $1,863,000 or 2 percent from the December 31, 2001 balance of
$110,393,000. The reduction in the loan pool participations is primarily due to
collections made in the normal course of business. 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 Company was the
winning bidder on three loan pool packages during the first quarter of 2002
totaling $8,397,000. The average loan pool participation balance of $106,412,000
for the first three months of 2002 was $35,274,000 or 50 percent higher than the
average balance of $71,138,000 for the first quarter of 2001.

Deposits

Total deposits as of March 31, 2002 were $387,295,000 compared with $378,645,000
as of December 31, 2001. Certificates of deposit remain the largest category of
deposits at March 31, 2002 representing approximately 54 percent of total
deposits. Deposits grew 2 percent during the first quarter of 2002.

Borrowed Funds/Notes Payable

The Company had no Federal Funds purchased on March 31, 2002. There was
$10,650,000 in Federal Funds purchased on December 31, 2001. During the first
quarter of 2002, the Company had an average balance of Federal Funds purchased
of $2,581,000. Advances from the Federal Home Loan Bank totaled $92,204,000 as
of March 31, 2002 compared with $91,174,000 as of December 31, 2001. Notes
payable increased to $12,200,000 on March 31, 2002 from $9,200,000 on December
31, 2001 as the Company utilized this funding mechanism to acquire loan pool
participations.

Nonperforming Assets

The Company's nonperforming assets totaled $4,439,000 (1.39 percent of total
loans) as of March 31, 2002, compared to $3,670,000 (1.08 percent of total
loans) as of December 31, 2001. All nonperforming asset totals and related
ratios exclude the loan pool participations. The following table presents the
categories of nonperforming assets as of March 31, 2002 compared with December
31, 2001:

                                          ======            ======

From December 31, 2001 to March 31, 2002, nonaccrual loans increased $351,000 as
the result of concerns with the quality of an agricultural line of credit. Loans
ninety days past due increased $543,000. The increase in loans ninety days past
due was attributable to one large agricultural construction credit that is
expected to be rolled into permanent financing when the construction is
complete. Other real estate owned decreased by $125,000 as property held in this
category was reduced to its current market value. The Company's allowance for
loan losses as of March 31, 2002 was $3,600,000, which was 1.15 percent of total
loans as of that date. This compares with an allowance for loan losses of
$3,381,000 as of December 31, 2001, which was 1.05 percent of total loans. As of
March 31, 2002, the allowance for loan losses was 82.21 percent of nonperforming
loans compared with 96.99 percent as of December 31, 2001. Based on the inherent
risk in the loan portfolio, management believes that as of March 31, 2002, the
allowance for loan losses is adequate. For the three months ended March 31,
2002, the Company's net loan charge-offs were $41,000 compared with net
charge-offs of $18,000 during the quarter ended March 31, 2001.

Capital Resources

Total shareholders' equity was 9.3 percent of total assets as of March 31, 2002
and as of December 31, 2001. The Company's Tier 1 Capital Ratio was 10.2 percent
of risk-weighted assets as of March 31, 2002 and was 10.0 percent as of December
31, 2001, 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 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 March
31, 2002, 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 quarter of 2002, the Company repurchased 5,000
shares of common stock on the open market in accordance with the terms of its'
previously-approved stock repurchase authorization.

Liquidity

<PAGE>

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 $19,747,000 as of March 31, 2002, compared with $15,837,000 as
of December 31, 2001. Most of the increase during the quarter was 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 March 31, 2002 to meet the needs of borrowers and depositors.

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, 2001, from that disclosed in the Company's 2001 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 three months of
2002 changed when compared to 2001.

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
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, 2001.

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.

Critical Accounting Policies

<PAGE>

The Company has identified two critical accounting policies and practices
relative to the financial condition and results of operation. These two
accounting policies relate to the allowance for loan losses and to loan pool
accounting.

         The allowance for loan losses is based on management's opinion, and is
adequate to absorb losses in the existing portfolio. In evaluating the
portfolio, management takes into consideration numerous factors, including
current economic conditions, prior loan loss experience, the composition of the
loan portfolio, and management's estimate of probable credit losses. The
allowance for loan loss is established through a provision for loss based on
management's evaluation of the risk inherent in the loan portfolio, the
composition of the portfolio, specific impaired loans, and current economic
conditions. Such evaluation, which includes a review of all loans on which full
collectibility may not be reasonably assured, considers among other matters, the
estimated net realizable value or the fair value of the underlying collateral,
economic conditions, historical loss experience, and other factors that warrant
recognition in providing for an adequate allowance for loan loss.

         The loan pool accounting practice relates to management's opinion that
the investment amount reflected on the Company's financial statements does not
exceed the estimated net realizable value or the fair value of the underlying
collateral securing the purchased loans. In evaluating the purchased loan
portfolio, management takes into consideration many factors, including the
borrowers' current financial situation, the underlying collateral, current
economic conditions, historical collection experience, and other factors
relative to the collection process.

         In the event that management's evaluation of the level of the allowance
for loan losses is inadequate, the Company would need to increase its provision
for loan losses. If the estimated realizable value of the loan pool
participations is understated, the Company's yield on the loan pools would be
reduced.
