West Bancorporation, Inc.
Notes to Consolidated Financial Statements
(unaudited)

1. Basis of Presentation

The accompanying consolidated statements of income for the three and nine months
ended September 30, 2006 and 2005, the consolidated statements of stockholders'
equity, comprehensive income, and cash flows for the nine months ended September
30, 2006 and 2005, and the consolidated balance sheets as of September 30, 2006
and December 31, 2005, include the accounts and transactions of the Company and
its wholly-owned subsidiaries, West Bank, WB Capital Management Inc. d/b/a VMF
Capital and Investors Management Group, Ltd. (IMG). 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, 2006, and the
results of operations and cash flows for the three and nine months ended
September 30, 2006 and 2005.

The results for these interim periods may not be indicative of results for the
entire year or for any other period.

2. Earnings Per Common Share

Earnings per share represent income available to common shareholders divided by
the weighted average number of shares outstanding during the period. The Company
has no common equivalent shares that could cause dilution. The weighted average
number of shares outstanding for the three months ended September 30, 2006 and
2005 was 17,536,765 and 17,536,935, respectively, and the weighted average
number of shares outstanding for the nine months ended September 30, 2006 and
2005 was 17,536,878 and 17,536,935, respectively.

On July 19, 2006, the Board of Directors of the Company declared a 5 percent
common stock dividend which was paid on August 14, 2006 to shareholders of
record on July 31, 2006. Fractional shares resulting from the stock dividend
were paid in cash. The number of outstanding common shares and earnings per
common share in the accompanying financial statements and footnotes reflect the
5 percent common stock dividend.

3. Commitments

In the normal course of business, the Company enters into commitments to extend
credit such as loan commitments and standby letters of credit to meet the
financing needs of its customers. These commitments expose the Company to
varying degrees of credit and market risk and are subject to the same credit
reviews as those recorded on the balance sheet. For additional information on
credit extension commitments see Note 13 of the Company's 2005 consolidated
financial statements. The Company's commitments as of September 30, 2006 and
December 31, 2005, are approximately as follows:

4. Segment Information

An operating segment is generally defined as a component of a business for which
discrete financial information is available and whose operating results are
regularly reviewed by the chief operating decision-maker. The Company's primary
business segments are banking and investment advisory services. The banking
segment generates revenue through interest and fees on loans, service charges on
deposit accounts, interest on investment securities and fees for trust services.
The banking segment includes West Bank and the Company, as the holding company's
operation is similar to that of the bank. The investment advisory segment
generates revenue by providing investment portfolio management services to
individuals, retirement plans, corporations, foundations, endowments and public
entities. The investment advisory segment includes VMF Capital and IMG. The
"Other" column represents the elimination of intercompany balances. The
acquisition of IMG on December 30, 2005 is the reason for the significant
increase in investment advisory fees. In prior year reporting periods the
investment advisory segment was included in the "Other" column. Selected
financial information on the Company's segments is presented below for the three
and nine months ended September 30, 2006 and 2005 (dollars in thousands).

5. Impact of New Financial Accounting Standards

In February 2006, the Financial Accounting Standards Board (FASB) issued SFAS
No. 155, Accounting for Certain Hybrid Financial Instruments. SFAS No. 155 is an
amendment of SFAS No. 133, Accounting for Derivative Instruments and Hedging
Activities, and SFAS No. 140, Accounting for Transfers and Servicing of
Financial Assets and Extinguishments of Liabilities. This Statement eliminates
the exemption from applying Statement 133 to interests in securitized financial
assets so that similar instruments are accounted for similarly regardless of the
form of the instruments. The Statement also allows an entity to elect fair value
measurement at acquisition, at issuance, or when a previously recognized
financial instrument is subject to a remeasurement event, on an
instrument-by-instrument basis. This Statement is effective for the Company
beginning on January 1, 2007. The Company does not expect this Statement to have
a material effect on its financial condition or results of operations.

In March 2006, the FASB issued SFAS No. 156, Accounting for Servicing of
Financial Assets. SFAS No. 156 is an amendment of SFAS No. 140. SFAS No. 156
requires an entity to recognize a servicing asset or liability each time it
undertakes an obligation to service a financial asset and requires each
servicing asset or liability to be initially measured at fair value. Entities
are permitted to choose the fair value measurement method or the amortization
method for subsequent reporting periods. This Statement is effective for the
Company beginning on January 1, 2007. The Company does not expect this statement
to have a material effect on its financial condition or results of operations.

In July 2006, the FASB issued Interpretation No. 48, Accounting for Uncertainty
in Income Taxes. Interpretation No. 48 provides clarification on accounting for
uncertainty in income taxes recognized in an enterprise's financial statements
in accordance with FASB No. 109, Accounting for Income Taxes. The Interpretation
prescribes a recognition threshold and measurement attribute for the financial
statement recognition and measurement of a tax position taken or expected to be
taken in a tax return, and provides for additional financial statement footnote
disclosure. Interpretation No. 48 is effective for the Company beginning on
January 1, 2007. The Company is currently evaluating the potential impact this
Interpretation could have on its financial condition or results of operations.

In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements. SFAS
No. 157 establishes a framework for measuring fair value in generally accepted
accounting principles, expands disclosures about fair value measurements and
applies whenever other standards require or permit assets or liabilities to be
measured at fair value. It does not expand the use of fair value in any new
circumstances. This Statement is effective for the Company beginning on January
1, 2008. The Company does not expect this Statement to have a material effect on
its financial condition.

In September 2006, the FASB issued SFAS No. 158, Employers' Accounting for
Defined Benefit Pension and Other Postretirement Plans. SFAS No. 158 is an
amendment of SFAS Nos. 87, 88, 106 and 132R. This Statement requires employers
to fully recognize the overfunded or underfunded status of a defined benefit
retirement plan, retiree healthcare and other postretirement plans as an asset
or liability in their financial statements as of the end of the fiscal year.
This Statement is effective for the Company for 2006. The Company does not
expect this Statement to have a material effect on its financial condition or
results of operations.

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. Material estimates that are
particularly susceptible to significant change in the near term are the
allowance for loan losses and fair value of financial instruments.

7. Critical Accounting Policies

Management has identified its most critical accounting policy to be that related
to the allowance for loan losses. The allowance for loan losses is established
through a provision for loan losses charged to expense. Loans are charged
against the allowance for loan losses when management believes that
collectibility of the principal is unlikely. The Company has policies and
procedures for evaluating the overall credit quality of its loan portfolio
including timely identification of potential problem credits. On a quarterly
basis, management reviews the appropriate level for the allowance for loan
losses incorporating a variety of risk considerations, both quantitative and
qualitative. Quantitative factors include the Company's historical loss
experience, delinquency and charge-off trends, collateral values, known
information about individual loans and other factors. Qualitative factors
include the general economic environment in the Company's market area and the
expected trend of those economic conditions. To the extent actual results differ
from forecasts and management's judgment, the allowance for loan losses may be
greater or less than future charge-offs.

8. Reclassifications

Minor reclassifications were made to certain categories in the prior year's
statement of cash flows to conform to the current year's presentation.

                 THREE AND NINE MONTHS ENDED SEPTEMBER 30, 2006

OVERVIEW

The following discussion is provided for the consolidated operations of the
Company, which includes its wholly-owned banking subsidiary, West Bank ("Bank")
and its wholly-owned investment advisory subsidiaries, WB Capital Management
Inc. d/b/a VMF Capital ("VMF Capital") and Investors Management Group, Ltd.
(IMG). It focuses on the consolidated results of operations for the three and
nine months ended September 30, 2006, compared to the same periods in 2005, and
on the consolidated financial condition of the Company and its subsidiaries at
September 30, 2006, compared to December 31, 2005.

Net income for the three months ended September 30, 2006, was $4,977,000, which
was virtually the same as the $4,963,000 reported for the same period in 2005.
Increases in net interest income, service charges on deposit accounts and
investment advisory fees were offset by increases in operating expenses.

For the first nine months of 2006, net income declined 2.6 percent from the
prior year to $14,404,000, or $.82 per share. Net interest income for the first
nine months of 2006 was $669,000 higher than the previous year primarily because
of the $110 million increase in average earning assets. Compared to the prior
year, the increases in net interest income and investment advisory fees were
more than offset by increases in noninterest expense. The nine months ended
September 30, 2006 also included net realized losses on the sale of investment
securities of $147,000 compared to net gains of $202,000 for the same period in
2005. Current year results include the operations of IMG, which was acquired on
December 30, 2005.

The net interest margin for the three and nine months ended September 30, 2006,
declined 24 and 27 basis points, respectively, compared to the same periods one
year ago. The cost of funds (deposits and borrowings) has increased faster than
the yield on earning assets (loans and investments).

Year-to-date noninterest income was 40.0 percent higher than last year due the
increase in investment advisory fees earned by IMG. Net income from the
investment advisory segment of the company totaled $102,000 for the third
quarter of 2006, compared to $128,000 for the third quarter of 2005.
Year-to-date net income from this segment totaled $404,000, compared to $274,000
for the same period in 2005.

Year-to-date noninterest expense was 34.1 percent higher than a year ago,
primarily due to the acquisition of IMG, increases in compensation and related
benefit expenses, occupancy costs and intangible amortization.

Fluctuations in net interest income can result from the combination of changes
in the volumes of asset and liability categories and changes in interest rates.
Net interest margin is a measure of the net return on interest-earning assets
and is computed by dividing annualized tax-equivalent net interest income by the
average of total interest-earning assets for the period. The net interest margin
for the third quarter was 3.29 percent, which was 24 basis points lower than the
same quarter last year and 6 basis points lower than the second quarter of 2006.
The decline from the prior quarter was due to continued increases in market
rates on deposits which have increased faster than the yields on earning assets.
The Company's tax-equivalent net interest income for the nine months ended
September 30, 2006, increased $560,000 compared to the nine months ended
September 30, 2005.

Taxable-equivalent interest income and fees on loans increased $14.2 million in
the first nine months of 2006 compared to the same period in 2005, due to the
combination of a higher volume of outstanding loans and increasing yields.
Average loans were $157 million higher than the first nine months of last year.
The average yield on loans increased to 7.29 percent for the first nine months
of 2006, compared to 6.30 percent for the same period in 2005. The yield on the
Company's loan portfolio is affected by the mix of the portfolio, the effects of
competition, the interest rate environment and the amount of non-accrual loans.
The interest rate environment can influence the volume of new loan originations
and the mix of variable rate versus fixed rate loans. Competition for loans in
the market areas served by the Company remains strong.

The average balance of investment securities was $50.8 million lower than last
year while the yield has increased 27 basis points. Most purchases of investment
securities during the first nine months of 2006 have been callable agency bonds
with maturities less than ten years or municipal bonds with maturities less than
twenty years.

The average rate paid on deposits for the first nine months of 2006 increased to
3.84 percent from 2.20 percent for the same period last year. This increase is
primarily the result of an increase in market interest rates and the shift in
funds from money market and savings accounts to certificates of deposit.
Customers have made such transfers to maximize their earnings. Compared to the
first nine months of last year, the average balance of higher rate certificates
of deposit was up $194.6 million. The increase consisted of jumbo certificates
of deposit, which generally bear higher interest rates than the other deposit
categories; and wholesale certificates of deposit, which have been used as an
alternative to short-term borrowings. The average balances of money market and
savings accounts, which typically have lower rates, were $17.9 million and $12.4
million lower, respectively.

The average balance of borrowings for the first nine months of 2006 was $47.9
million lower than a year ago. Short-term borrowings, which consisted primarily
of federal funds purchased and borrowings from the Federal Home Loan Bank of Des
Moines (FHLB), averaged $52.6 million less than in the first nine months of
2005, due to utilizing wholesale time deposits. Long-term borrowings averaged
$4.7 million more than in the first nine months of 2005, due to borrowing funds
to finance the acquisition of IMG in December 2005. The Company has minimized
its use of FHLB short-term advances because rates associated with wholesale
deposits have been slightly lower and wholesale deposits do not require
collateral.

</TABLE>

Charge-offs in the three months ended September 30, 2006, increased
significantly compared to the prior year. Three loans that had been classified
as non-accrual accounted for $586,000 of the total charge-offs. The three loans
met the criteria for an in-substance foreclosure, which occurs when the borrower
has little or no equity in the collateral securing a loan. Charge-offs were
incurred for the difference between the carrying value and the net realizable
value of the properties securing the loans. A total of $1,730,000 was
transferred into other real estate owned.

The provision for loan losses represents charges made to earnings to maintain an
adequate allowance for loan losses. The allowance for loan losses is
management's best estimate of probable losses inherent in the loan portfolio as
of the balance sheet date. Factors considered in establishing an appropriate
allowance include: an assessment of the financial condition of the borrower; a
realistic determination of value and adequacy of underlying collateral; the
condition of the local economy and the condition of the specific industry of the
borrower; an analysis of the levels and trends of loan categories; and a review
of delinquent and classified loans.

The adequacy of the allowance for loan losses is evaluated quarterly by
management and reviewed by the Bank's Board of Directors. This evaluation
focuses on specific loan reviews, changes in the type and volume of the loan
portfolio given the current and forecasted economic conditions and historical
loss experience. Any one of the following conditions may result in the review of
a specific loan: concern about whether the customer's cash flow or net worth is
sufficient to repay the loan; delinquency status; criticism of the loan in a
regulatory examination; the suspension of interest accrual; or other reasons,
including when the loan has other special or unusual characteristics that
suggest special monitoring is warranted.

While management uses available information to recognize losses on loans,
further reduction in the carrying amounts of loans may be necessary based on
changes in local economic conditions. In addition, regulatory agencies, as an
integral part of their examination process, periodically review the estimated
losses on loans. Such agencies may require the Company to recognize additional
losses based on their judgment about information available to them at the time
of their examinations. See also the discussion of nonperforming assets later in
this report.

Noninterest income results from the charges and fees collected by the Company
from its customers for various services performed and miscellaneous other income
and gains (or losses) from the sale of investment securities. Service charges on
deposit accounts declined slightly on a year-to-date basis, while implementation
of pricing changes in the third quarter of 2006 caused an increase in return
check charges compared to the same quarter in 2005. Trust fees increased 7.5
percent in the first nine months of 2006 compared to the prior year as a result
of the combination of new business and revised fee schedules.

Investment advisory fees are fees earned by VMF Capital and IMG. The significant
increase in investment advisory fees in the current quarter and year-to-date was
due to the acquisition of IMG on the last day of 2005. Revenue declined slightly
in the third quarter of 2006 compared to the second quarter because of the loss
of a customer. New business development efforts were hampered somewhat due to
the significant amount of time and effort spent on planning for the merger.
Effective October 1, 2006, VMF Capital and IMG have merged and will operate as
WB Capital Management Inc. Combining the two companies will allow for more
effective client service.

The Company recognized losses from the sale of investment securities in the
first nine months of 2006 as lower yielding investments were sold with the
proceeds being reinvested at higher yields. By the end of the year, the
additional income earned on the purchased investments will more than make up for
the losses recognized in the first nine months of the year. Debit card usage
fees continued to increase as customers continued to expand utilization of this
convenient payment method. Check printing income increased due to new contract
terms with the vendor. Gains from the sale of residential mortgages in the
secondary market were down because increases in market interest rates have
reduced the volume of originations. Noninterest-related loan fees in 2005
included the recognition of a one-time fee for a loan commitment that was
terminated by a customer.

The increase in salaries and benefits included compensation and benefits for
approximately 24 employees related to the acquisition of IMG, approximately 15
more employees at West Bank in 2006 than a year ago due to growth of the bank,
annual compensation adjustments and higher medical insurance premiums.

Occupancy expenses were higher this year because of one additional location
related to IMG and increased depreciation expense related to furniture and
equipment additions throughout the Company. Early in the year the Clive office
of VMF Capital was relocated to the same facility as IMG and is using space that
was already leased. A new tenant has agreed to utilize the former VMF Capital
space, and the landlord canceled VMF Capital's remaining lease. A charge of
$32,000 was recorded to occupancy expense in the second quarter as a result of
terminating that lease. In the third quarter, one of the Des Moines metropolitan
branches was relocated to a higher traffic location. An agreement to sell the
former branch is in place and is expected to result in a gain on sale of
approximately $112,000 in the fourth quarter of 2006.

Data processing expense and insurance expense were higher primarily due to the
acquisition of IMG. Supplies declined as the first quarter of 2005 included
reprinting many brochures due to product and pricing changes. Marketing and
business development related costs increased as a result of significant efforts
to increase and expand current and new customer relationships at the Bank and
the investment advisory subsidiaries.

Professional fees increased due to the acquisition of IMG, higher audit fees and
higher legal fees. Legal fees increased because of fees associated with one
non-accrual loan and the cost of defending a lawsuit filed on June 20, 2006,
which was reported on a Form 8-K filed on June 26, 2006.

Consulting fees for 2006 included expenses incurred by IMG, but have declined as
2005 expense included fees for implementation of software programs to assist
with asset-liability management. Intangible amortization increased as the result
of recording client base and employment/noncompete intangibles in the
acquisition of IMG.

Income Tax Expense

The Company incurred income tax expense of $6.7 million for the nine months
ended September 30, 2006 compared to $7.0 million for the nine months ended
September 30, 2005. The effective income tax rate as a percent of income before
taxes for the three and nine months ended September 30, 2006 and 2005 held
steady at approximately 32 percent.

FINANCIAL CONDITION

Total assets as of September 30, 2006, were $1.3 billion, a slight increase from
$1.2 billion at December 31, 2005. The increase is primarily due to increased
loan volumes, which were funded primarily by wholesale certificates of deposit.

Investment Securities

Investment securities available for sale declined approximately $2.7 million
from December 31, 2005, to $267.6 million. During the nine months ended
September 30, 2006, $16.2 million of lower yielding securities were sold, with
the majority of the proceeds reinvested in higher yielding securities. On a
quarterly basis, the investment securities portfolio is reviewed for
other-than-temporary impairment. As of September 30, 2006, existing unrealized
losses are considered to be temporary in nature due to market interest rate
fluctuations and, accordingly, no impairment adjustment has been recorded.

Loans and Non-performing Assets

Loans outstanding increased approximately $44.4 million from December 31, 2005,
to September 30, 2006. The increase was primarily attributable to growth in real
estate construction and commercial loans.

Two loans accounted for $3.7 million of the total non-accrual loans. As
previously reported, one commercial loan totaling $3.8 million secured by
commercial real estate used in the operation of the customer's business and
farmland was placed on non-accrual status in the fourth quarter of 2005. As
negotiations for a resolution have progressed, the farmland portion of this
relationship was moved to other real estate owned at an estimated net realizable
value of $1.6 million. The remaining portion of the loan was written down by
$292,000 to reflect the value that management anticipates will be realized from
the remaining collateral. Payments totaling $115,000 were applied to the
principal balance of this loan during the first nine months of 2006. Beginning
in July 2006, approximately $20,000 per month for the remainder of 2006 will be
applied to the carrying value of this loan. These funds will come from a
short-term rental agreement with a third party. The second loan was associated
with the lawsuit disclosed in last quarter's report and was placed on
non-accrual status in August 2006. The amount of the loan is $1.9 million. The
funds to pay off this loan are currently being held at the co-defendant bank.
Management believes this loan will be paid in full from these funds. The
remaining balance of loans in non-accrual status was $544,000, and consisted of
loans to 16 different borrowers. The amount of loans past due 90 days and still
accruing interest declined to zero from $767,000 at December 31, 2005, due to a
concerted effort to collect delinquent payments. Finally, two construction loans
totaling $425,000 were written down by $295,000, and the remaining balance of
$130,000 was transferred to other real estate owned during the third quarter of
2006.

Reference is also made to the information and discussion earlier in this report
under the heading "Provision for Loan Losses and the Related Allowance for Loan
Losses".

Deposits

Total deposits as of September 30, 2006, were $986 million compared with $945
million as of December 31, 2005. The savings category of deposits, which
includes money market accounts that are liquid accounts and therefore pay
relatively lower interest rates, declined approximately $64 million. A portion
of those funds moved into the time certificates of deposit in excess of $100,000
category as customers attempted to maximize the interest earned on those funds.
It is expected that this trend will continue. Time deposits increased a total of
$116 million. In addition to the movement of money market balances, the Bank
utilized wholesale certificates of deposit as a lower cost alternative source of
funds compared to borrowing from the FHLB or federal funds.


                                       18

Borrowings

The balance of federal funds purchased and securities sold under agreement to
repurchase was approximately the same as the end of 2005. Federal funds
purchased include funds sold to West Bank by approximately 25 banks throughout
Iowa as part of the correspondent bank services provided by West Bank. The
balance of Federal funds purchased from correspondent banks throughout Iowa will
fluctuate depending upon the loan demand and investment strategy of those banks.
The Bank also purchases federal funds from regional and national correspondent
banks as necessary for short-term liquidity needs. The balance of other
short-term borrowings consisted of Treasury, Tax and Loan option notes and the
short-term portion of an installment note payable to a regional correspondent
bank. The note was obtained in December 2005 to fund the acquisition of IMG.
Long-term borrowings declined $12.3 million due to FHLB advances being called in
the third quarter of 2006. In early October 2006, the decision was made to
replace $50 million of wholesale deposits with two $25 million ten-year callable
FHLB advances. One of the advances is callable in one year and the other is
callable at the end of three years. The weighted average rate on the new
callable FHLB advances is 4.12 percent, which is significantly less than the
cost of wholesale certificates of deposit at this time.

Liquidity and Capital Resources

The objective of liquidity management is to ensure the availability of
sufficient cash flows to meet the requirements of depositors and borrowers, all
corporate financial commitments and to capitalize on opportunities for
profitable business expansion. The Company's principal source of funds is
deposits, including demand, money market, savings and certificates of deposit.
Other sources include principal repayments on loans, proceeds from the maturity
and sale of investment securities, federal funds purchased, repurchase
agreements, advances from the Federal Home Loan Bank and funds provided by
operations. Liquidity management is conducted on both a daily and a long-term
basis. Investments in liquid assets are adjusted based on expected loan demand,
projected loan maturities and payments, expected deposit flows, and the
objectives set by the Company's asset-liability management policy. The Company
had liquid assets (cash and cash equivalents) of $30.6 million as of September
30, 2006, compared with $40.7 million as of December 31, 2005. Securities
available for sale may be sold prior to maturity to meet liquidity needs, to
respond to market changes or to adjust the Company's interest rate risk
position. The Company had additional borrowing capacity of approximately $103
million available from the FHLB at September 30, 2006, and has a $2.5 million
unsecured line of credit through a large regional correspondent bank. In
addition, the Bank has $85 million available through unsecured federal funds
lines of credit with correspondent banks. The Bank was utilizing $16.8 million
of those lines of credit at September 30, 2006. Management believes the
combination of high levels of potentially liquid assets, positive cash flows
from operations and additional borrowing capacity provided strong liquidity for
the Company at September 30, 2006.

The Company's total stockholders' equity increased to $111.0 million at
September 30, 2006, from $104.5 million at December 31, 2005. Total
stockholders' equity was 8.7 percent of total assets as of September 30, 2006,
and 8.4 percent on December 31, 2005. No material capital expenditures or
material changes in the capital resource mix are anticipated at this time.

On April 19, 2006, the Company's Board of Directors authorized $5 million to be
used for the buy-back of Company common stock for a period of 12 months. No
repurchases took place during the nine months ended September 30, 2006.

On July 19, 2006, the Board of Directors of the Company declared a 5 percent
common stock dividend which was paid on August 14, 2006 to shareholders of
record on July 31, 2006. Fractional shares resulting from the stock dividend
were paid in cash. The number of outstanding common shares and earnings per
common share in the accompanying financial statements and footnotes reflect the
5 percent common stock dividend.

Quantitative measures established by regulation to ensure capital adequacy
require the Company and the Bank to maintain minimum amounts and ratios (set
forth in the following table) of total and Tier 1 capital to risk-weighted
assets and of Tier 1 capital to average assets. Management believes the capital
levels of the Company and the Bank met all capital adequacy requirements to
which they were subject at September 30, 2006.

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
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
