amended. The Company owns 100 percent of the stock of one state banking
subsidiary and two registered investment advisory firms, as described below. All
of the Company's banking operations are conducted in the State of Iowa and
primarily within the Des Moines and Iowa City, Iowa metropolitan areas. The
Company's registered investment advisory firms' operations are conducted
primarily in the Des Moines and Cedar Rapids, Iowa metropolitan areas, but they
also have clients throughout the United States. The Company does not engage in
any material business activities apart from its ownership of its banking and

The Company was organized and incorporated on May 22, 1984, under the laws of
the State of Iowa to serve as a holding company for its principal banking
subsidiary, West Bank (sometimes referred to as the "Bank") whose main office is
located in West Des Moines, Iowa.

The principal sources of Company revenue are derived from West Bank: (1)

West Bank's lending activities consist primarily of short-term and medium-term
commercial and real estate loans, business operating loans and lines of credit,

through 59 of the Company's Appendix to the Proxy Statement, which was filed on

BANKING SUBSIDIARY

West Bank, West Des Moines, Iowa. West Bank is a state chartered commercial bank
insured by the Federal Deposit Insurance Corporation ("FDIC"), organized in

Hawkeye State Bank in Iowa City, Iowa. Assets acquired in the transaction
totaled approximately $129 million at two offices in Iowa City. In December
2004, the bank opened an additional office in Coralville, which is in the Iowa
City metropolitan area. West Bank provides full-service banking to businesses
and residents primarily in the Des Moines and Iowa City metropolitan areas as
well as correspondent services to banking organizations primarily located in
Iowa. It provides a variety of products and services designed to meet the needs
of the markets it serves. It has an experienced staff of bank officers who have
spent the majority of their banking careers with West Bank and local financial
service organizations, and who emphasize long-term customer relationships. West
Bank conducts business out of eight full-service offices within the Des Moines

Investors Management Group, Ltd. ("IMG"), West Des Moines, Iowa. IMG is a
registered investment advisor regulated by the Securities and Exchange
Commission providing portfolio management services to insurance companies,
banks, political subdivisions, mutual funds, associations, other organizations
and individual investors. The subsidiary specializes in fixed income portfolios.

As of December 31, 2005, IMG had approximately $4 billion in assets under
management. IMG was acquired on December 30, 2005, and, therefore, no operating
results for IMG are included in the Company's consolidated financial statements
for 2005.

BUSINESS STRATEGY AND OPERATIONS

The Company is a bank holding company serving primarily the Des Moines and Iowa
City metropolitan areas. As previously discussed, during 2003, the Bank grew
through the acquisition of two offices in Iowa City. In 2004 and 2005, growth
resulted from expanding existing relationships, new customer relationships, and
opening a new office late in 2004. The Company's business strategy is to
emphasize strong personal and business relationships, and to provide products
and services that meet the needs of its customers. The Company emphasizes strong
cost controls while striving to achieve return on equity and net income goals.
To accomplish these goals, West Bank focuses on small to medium size businesses
that traditionally wish to develop an exclusive relationship with a single bank.
West Bank has the size to give the personal attention required by business
owners, in addition to the credit expertise to help businesses meet their goals.

West Bank offers a full range of deposit services that are typically available
in most financial institutions, including checking accounts, savings accounts,
money market accounts and time certificates of deposit. One major goal of the
Bank's product mix is to keep the product offerings as simple as possible, both
in terms of the number of products and the features and benefits of the
individual services. The transaction accounts and time certificates are tailored
to the marketplace at competitive rates. In addition, the Bank offers retirement
accounts such as Individual Retirement Accounts. The FDIC insures all deposit
accounts up to the maximum amount. The Bank solicits these accounts from
small-to-medium sized businesses and from individuals who live and/or work
within its market area. Occasionally, one particular customer may have balances
in short-term deposits that represent approximately 15 percent of the Bank's
total deposits. The Company does not believe that the loss of deposits of any
one customer or of a few customers would have an adverse effect on the Bank's
operation or erode its core deposit base.

Loans are provided to creditworthy borrowers regardless of their race, color,
national origin or ancestry, religion, sex, age, marital status, sexual
orientation, disability, veteran status, receipt of public assistance, or any
other basis prohibited by law. West Bank intends to fulfill this commitment
while maintaining prudent credit standards. In the course of fulfilling this
obligation to meet the credit needs of the marketplace it serves, West Bank will
consider each credit application without regard to the fact that the applicant
may reside in a low to moderate income neighborhood, or to the geographic
location of the residence, property, or business within the market area.

The Bank provides quality financial products and services such as telephone and
internet banking and trust services that meet the banking needs of its customers
and its market place. The loan programs and acceptance of certain loans may vary
from time to time depending on the funds available and regulations governing the
banking industry. West Bank offers all basic types of credit to its marketplace,
including commercial, real estate, and consumer loans. The types of loans within
these categories are as follows:

Commercial Loans. Commercial loans are typically made to sole proprietors,
partnerships, corporations and other business entities such as municipalities
and individuals, where the loan is to be used primarily for business purposes.
These loans are typically secured by assets owned by the borrower and often
involve personal guarantees given by the owners of the business. The types of
loans that West Bank offers include financing guaranteed under Small Business
Administration programs, operating and working capital loans, loans to finance
equipment and other capital purchases, commercial real estate loans, business
lines of credit, term loans, loans to professionals, and letters of credit.

                                       5
<PAGE>

Consumer Loans. Consumer loans are typically available to finance home
improvements and consumer purchases. These loans are made on either a secured or
an unsecured basis. The types of loans that West Bank offers include loans to
finance automobiles, trucks, boats and recreational vehicles, personal loans and
lines of credit, home equity lines of credit, home improvement and
rehabilitation loans, and residential real estate loans.

Other types of credit programs, such as loans to nonprofit organizations and to
public entities for community development, also are available.

West Bank offers trust services typically found in a commercial bank with trust
powers, including the administration of estates, conservatorships, personal and
corporate trusts, and agency accounts.

West Bank also earns fees from the origination of residential mortgages that are
sold in the secondary real estate market without retaining the mortgage
servicing rights.

The Bank offers traditional banking services, such as safe deposit boxes, wire
transfers, direct deposit of payroll and social security checks, automated
teller machine access, and automatic drafts (ACH) for various accounts.

West Bank offers correspondent bank services to community banks located
primarily in Iowa. These services include the buying and selling of federal
funds as well as purchases and sales of loan participations.

CREDIT MANAGEMENT

The Company strives to achieve sound credit risk management by establishing
uniform credit policies and underwriting criteria for West Bank's loan
portfolio. The Bank diversifies the types of loans offered and is subject to
regular credit examinations by regulators, annual external loan audits, internal
loan reviews and an internal annual review of large loans. The Bank attempts to
identify potential problem loans early, charge off loans promptly and maintain
an adequate allowance for loan losses. The Bank has established credit
guidelines for the lending activities that include guidelines relating to the
more commonly requested loan types, as follows:

Commercial Real Estate Loans - Commercial real estate loans are normally based
on loan-to-appraisal value ratios of not more than 75 percent and are secured by
a first priority lien position. Loans are typically subject to interest rate
adjustments no less frequently than seven years from origination, with a maximum
amortization period of 30 years. Projections and cash flows that demonstrate
ability to service debt within the amortization period are required. Property
and casualty insurance is required to protect the Bank's collateral interests. A
major risk factor for the Bank's commercial real estate loan portfolio, as well
as the other loan types described below, is the geographic concentration in the
Des Moines and Iowa City metropolitan areas. Loans are generally guaranteed by
the principal(s).

Commercial Operating Lines - These loans are made to businesses with normal
terms up to twelve months. The credit needs are generally seasonal with the
source of repayment coming from the entity's normal business cycle. Cash flow
reviews are completed to establish the ability to service the debt within the
terms of the loan. A first priority lien on the general assets of the business
normally secures these types of loans. Loan-to-value limits vary and are
dependent upon the nature and type of the underlying collateral and the
financial strength of the borrower. Loans are generally guaranteed by the
principal(s).

Commercial Term Loans - These loans are made to businesses to finance
equipment and other capital expenditures. Terms are generally the lesser of
seven years or the useful life of the asset. Term loans are normally secured by
the asset being financed and are often additionally secured with the general
assets of the business. Loan-to-value is generally a maximum of 75 percent of
the cost or value of the assets. Loans are normally guaranteed by the
principal(s).

Construction Loans - Construction loans on commercial real estate are normally
based on a loan-to-appraisal value ratio of not more than 75 percent and are
secured by a first priority lien position. Loan payments typically consist of
interest only for a term of 1-1/2 to 2 years. The interest rate is usually
variable, based on the prime rate. Residential construction loans are generally
for a term not to exceed one year based on a loan-to-appraisal value ratio of
not more than 80 percent and are secured by a first priority lien position.
Interest is normally paid monthly or quarterly based on a variable rate tied to
prime.

Residential First Mortgage Loans - Proceeds of these loans are used to buy or
refinance the purchase of residential real estate with the loan secured by a
first lien on the real estate. Most of the residential mortgage loans originated
by the Bank during the past year have been sold (including servicing rights) in
the secondary mortgage market due to the higher interest rate risk inherent in
the 15 and 30 year fixed rate terms consumers prefer. Loans that are originated
and not sold in the secondary market generally have higher interest rates and
have rate adjustment periods normally no longer than seven years. The maximum
amortization of first mortgage residential real estate loans is 30 years. The
loan-to-value ratios normally do not exceed 80 percent. Property insurance is
required on all loans to protect the Bank's collateral position.

                                       6
<PAGE>

Home Equity Term Loans - These loans are normally for home improvement or
other consumer purposes and are secured by a junior mortgage on residential real
estate. The loan-to-value ratios normally do not exceed 90 percent.

Home Equity Lines of Credit - The Bank offers a home equity line of credit
with a maximum term of 120 months. These loans are secured by a junior mortgage
on residential real estate and normally do not exceed a loan-to-value ratio of
90 percent with the interest adjusted quarterly.

Consumer Loans - Consumer loans are normally made under the following
guidelines: automobiles - loans on new and used automobiles generally will not
exceed 80 and 75 percent of the value, respectively; recreational vehicles and
boats - 75 percent of value; modular home loans have a maximum term of 180
months with the loan-to-value ratio generally not exceeding 80 percent. Each of
these loans is secured by a first priority lien on the assets and requires
insurance to protect the Bank's collateral position. The term for unsecured
loans generally does not exceed 24 months.

EMPLOYEES

At December 31, 2005, the Bank had a total of 140 full-time equivalent
employees, VMF Capital had 18 full-time equivalent employees, IMG had 25
full-time equivalent employees and the Company had no employees. Full-time
equivalents represent the number of people a business would employ if all of its
employees were employed on a full-time basis. It is calculated by dividing the
total number of hours worked by all full- and part-time employees by the number
of hours a full-time individual would work for a given period of time. Employees
are provided with a comprehensive program of benefits, including comprehensive
medical and dental plans, long-term and short-term disability coverage, and a
profit sharing plan with both 401(k) and employee stock ownership features.
Management considers its relations with employees to be satisfactory. Unions
represent none of the employees.

MARKET AREA

The Company operates one commercial bank with eight locations throughout the Des
Moines, Iowa metropolitan area and three locations in the Iowa City, Iowa
metropolitan area. West Bank's primary business includes providing business and
retail banking services and lending.

West Bank's main office is located in West Des Moines, Iowa, one of the fastest
growing communities in Iowa. The population of the Des Moines metropolitan area
is nearly 500,000. Des Moines is the capital of Iowa. Major employers are the
State of Iowa, Principal Financial Group, Pioneer Hi-Bred International, Inc.,
Wells Fargo, Central Iowa Hospital Corporation, Mercy Hospital Medical Center,
Hy-Vee Food Stores, Inc., and the Des Moines Independent School District.

The Company also operates two investment advisory subsidiaries. VMF Capital with
offices in West Des Moines and Cedar Rapids, Iowa has customers throughout Iowa
and the United States. The Company acquired IMG with headquarters in West Des
Moines, Iowa on December 30, 2005.

COMPETITION

The geographic market area served by West Bank is highly competitive with
respect to both loans and deposits. The Bank competes principally with other
commercial banks, savings and loans associations, credit unions, mortgage
companies, finance divisions of auto companies, and other service providers.
Some of these competitors are local, while others are statewide or nationwide.
The major commercial bank competitors include Bankers Trust Company, NA, a local
banking organization; a regional bank: Bank of the West (formerly Commercial
Federal Bank); and several nationwide banks: Wells Fargo Bank, Bank of America
and U.S. Bank, NA. Among the advantages such larger banks offer are their
ability to finance extensive advertising campaigns and to allocate their
investment assets to geographic regions of higher yield and demand. Such banks
offer certain services that are not offered directly by West Bank, but that may
be offered through correspondent banking institutions. These larger banking
organizations have much higher legal lending limits than West Bank and thus are
better able to finance large regional, national, and global commercial
customers.

In order to compete, to the fullest extent possible, with the other financial
institutions in its primary trade area, West Bank uses the flexibility that is
accorded by its independent status. This includes an emphasis on specialized
services, local promotional activities, and personal contacts by the Bank's
officers, directors, and employees. In particular, the Bank competes for
deposits principally by offering depositors a variety of deposit programs,
convenient office locations and hours and other personalized services. West Bank
competes for loans primarily by offering competitive interest rates, experienced
lending personnel with local decision-making authority and quality products and
services.

                                       7
<PAGE>

Pursuant to the FDIC's Summary of Deposits, as of June 30, 2005, there were 32
other banks and savings and loan associations within Polk County, Iowa, where
eight of the Bank's offices are located. West Bank ranked 4th based on total
deposits of all offices in Polk County. As of June 30, 2005, there were 14 other
banks and savings and loan associations within Johnson County, Iowa, where three
offices are located in the Iowa City area. West Bank, ranked 4th based on total
deposits of all offices in Johnson County. For the entire state, West Bank,
ranked 7th in terms of deposit size.

The Bank also competes with the financial markets for funds. Yields on corporate
and government debt securities and commercial paper affect the ability of
commercial banks to attract and hold deposits. Commercial banks also compete for
funds with money market instruments and similar investment vehicles offered by
competitors including brokerage firms, insurance companies, credit card issuers,
and retailers such as Sears. Money market funds offered by these types of
organizations have provided substantial competition for deposits. This trend
will likely continue in the future.

The Company anticipates bank competition will continue to change significantly
over the next several years as more banks, including the major regional and
nationwide banks, continue to consolidate. Smaller community banks continue to
move their charters or open branches in larger metropolitan areas in an attempt
to capture market share in a more diverse and growing economic environment.
Credit unions, because of their income tax advantage, will continue to show
substantial growth.

SUPERVISION AND REGULATION

The following discussion generally refers to certain statutes and regulations
affecting the banking industry. These references provide brief summaries and,
therefore, do not purport to be complete and are qualified in their entirety by
reference to those statutes and regulations. In addition, due to the numerous
statutes and regulations that apply to and regulate the operation of the banking
industry, many are not referenced below.

The Company and West Bank are subject to extensive federal and state regulation
and supervision. Regulation and supervision of financial institutions is
primarily intended to protect depositors and the FDIC rather than shareholders
of the Company. The laws and regulations affecting banks and bank holding
companies have changed significantly over recent years, particularly with the
passage of the Financial Services Modernization Act and the USA Patriot Act of
2001. There is reason to expect that similar changes will continue in the
future. Any change in applicable laws, regulations, or regulatory policies may
have a material effect on the business, operations, and prospects of the
Company. The Company is unable to predict the nature or the extent of the
effects on its business and earnings that any fiscal or monetary policies or new
federal or state legislation may have in the future.

The Company

The Company is a bank holding company by virtue of its ownership of West Bank,
and is registered as such with the Board of Governors of the Federal Reserve
System (the "Federal Reserve"). The Company is subject to regulation under the
Bank Holding Company Act of 1956, as amended (the "BHCA"), which subjects the
Company and the Bank to supervision and examination by the Federal Reserve.
Under the BHCA, the Company files with the Federal Reserve quarterly and annual
reports of its operations and such additional information as the Federal Reserve
may require.

Source of Strength to the Bank. The Federal Reserve takes the position that a
bank holding company is required to serve as a source of financial strength to
its subsidiary bank and may not conduct its operations in an unsafe or unsound
manner. In addition, it is the Federal Reserve's position that in serving as a
source of strength to its subsidiary bank, a bank holding company should use
available resources to provide adequate capital funds to its subsidiary bank
during periods of financial stress or adversity. It should also maintain the
financial flexibility and capacity to obtain additional resources for providing
assistance to its subsidiary bank. A bank holding company's failure to meet its
obligations to serve as a source of strength to its subsidiary bank will
generally be considered by the Federal Reserve to be an unsafe and unsound
banking practice, a violation of the Federal Reserve's regulations, or both.

Federal Reserve Approval. Bank holding companies must obtain the approval of the
Federal Reserve before they: (1) acquire direct or indirect ownership or control
of any voting stock of any bank if, after such acquisition, they would own or
control, directly or indirectly, more than 5 percent of the voting stock of such
bank; (2) merge or consolidate with another bank holding company; or (3) acquire
substantially all of the assets of any additional banks.

                                       8

Non-Banking Activities. With certain exceptions, the BHCA also prohibits bank
holding companies from acquiring direct or indirect ownership or control of
voting stock in any company other than a bank or bank holding company unless the
Federal Reserve finds the company's business to be incidental to the business of
banking. When making this determination, the Federal Reserve in part considers
whether allowing a bank holding company to engage in those activities would
offer advantages to the public that would outweigh possible adverse effects. The
Company obtained approval of the Federal Reserve to form VMF Capital in 2003 and
to acquire IMG in 2005. A bank holding company may engage in permissible
non-banking activities on a de novo basis, if the holding company meets certain
criteria and notifies the Federal Reserve within ten (10) business days after
the activity has commenced.

Under the Financial Services Modernization Act, an eligible bank holding company
may elect (with the approval of the Federal Reserve) to become a "financial
holding company." Financial holding companies are permitted to engage in certain
financial activities through affiliates that had previously been prohibited
activities for bank holding companies. Such financial activities include
securities and insurance underwriting and merchant banking. At this time, the
Company has not elected to become a financial holding company, but may choose to
do so at some time in the future.

Control Transactions. The Change in Bank Control Act of 1978, as amended,
requires a person or group of persons acquiring "control" of a bank holding
company to provide the Federal Reserve with at least 60 days prior written
notice of the proposed acquisition. Following receipt of this notice, the
Federal Reserve has 60 days to issue a notice disapproving the proposed
acquisition, but the Federal Reserve may extend this time period for up to
another 30 days. An acquisition may be completed before the disapproval period
expires if the Federal Reserve issues written notice of its intent not to
disapprove the action. Under a rebuttable presumption established by the Federal
Reserve, the acquisition of 10 percent or more of a class of voting stock of a
bank holding company with a class of securities registered under Section 12 of
the Securities Exchange Act of 1934, as amended, would constitute the
acquisition of control. In addition, any "company" would be required to obtain
the approval of the Federal Reserve under the BHCA before acquiring 25 percent
(or 5 percent if the "company" is a bank holding company) or more of the
outstanding shares of the Company, or otherwise obtain control of the Company.

Affiliate Transactions. The Company, West Bank, VMF Capital and IMG are deemed
affiliates within the meaning of the Federal Reserve Act, and transactions
between affiliates are subject to certain restrictions. Generally, the Federal
Reserve Act: (1) limits the extent to which the financial institution or its
subsidiaries may engage in "covered transactions" with an affiliate; and (2)
requires all transactions with an affiliate, whether or not "covered
transactions," to be on terms substantially the same, or at least as favorable
to the institution or subsidiary, as those provided to a non-affiliate. The term
"covered transaction" includes the making of loans, purchase of assets, issuance
of guarantees, and similar transactions.

State Law on Acquisitions. Iowa law permits bank holding companies to make
acquisitions throughout the state. However, Iowa currently has a deposit
concentration limit of 15 percent on the amount of deposits in the state that
any one banking organization can control and continue to acquire banks or bank
deposits (by acquisitions), which applies to all depository institutions doing
business in Iowa.

Banking Subsidiaries

Applicable federal and state statutes and regulations governing a bank's
operations relate, among other matters, to capital adequacy requirements,
required reserves against deposits, investments, loans, legal lending limits,
certain interest rates payable, mergers and consolidations, borrowings, issuance
of securities, payment of dividends, establishment of branches, and dealings
with affiliated persons.

West Bank is a state bank subject to primary federal regulation and supervision
by the Federal Deposit Insurance Corporation (the "FDIC") and the Iowa Division
of Banking. The federal laws applicable to the Bank regulate, among other
things, the scope of its business, its investments, its reserves against
deposits, the timing of the availability of deposited funds, and the nature and
amount of and collateral for loans. The laws and regulations governing the Bank
generally have been promulgated to protect depositors and the deposit insurance
fund of the FDIC and not to protect stockholders of such institutions or their
holding companies.

The FDIC has authority to prohibit banks under its supervision from engaging in
what it considers to be unsafe and unsound practices in conducting business. The
Federal Deposit Insurance Corporation Improvement Act of 1991 ("FDICIA")
requires federal banking regulators to adopt regulations or guidelines in a
number of areas to ensure bank safety and soundness, including internal
controls, credit underwriting, asset growth, earnings, management compensation,
and ratios of classified assets to capital. FDICIA also contains provisions that
are intended to change independent auditing requirements, restrict the
activities of state-chartered insured banks, amend various consumer banking
laws, limit the ability of "undercapitalized banks" to borrow from the Federal
Reserve's discount window, require regulators to perform periodic on-site bank
examinations, and set standards for real estate lending.

Borrowing Limitations. West Bank is subject to limitations on the aggregate
amount of loans that it can make to any one borrower, including related
entities. Subject to numerous exceptions based on the type of loans and
collateral, applicable statutes and regulations generally limit loans to one
borrower to 15 percent of total equity and reserves. West Bank is in compliance
with applicable loans to one borrower requirements.

                                       9
<PAGE>

FDIC Insurance. Generally, customer deposit accounts in banks are insured by the
FDIC for up to a maximum amount of $100,000. The FDIC has adopted a risk-based
insurance assessment system under which depository institutions contribute funds
to the FDIC insurance fund based on their risk classification. The FDIC may
terminate the deposit insurance of any insured depository institution if it
determines after an administrative hearing that the institution has engaged or
is engaging in unsafe or unsound practices, is in an unsafe or unsound condition
to continue operations, or has violated any applicable law.

Capital Adequacy Requirements. The Federal Reserve, the FDIC, and the Office of
the Comptroller of the Currency ("OCC") (collectively, the "Agencies") have
adopted risk-based capital guidelines for banks and bank holding companies that
are designed to make regulatory capital requirements more sensitive to
differences in risk profiles among banks and bank holding companies and account
for off-balance sheet items. Failure to achieve and maintain adequate capital
levels may give rise to supervisory action through the issuance of a capital
directive to ensure the maintenance of required capital levels. West Bank is in
compliance with applicable regulatory capital level requirements.

The current guidelines require all federally regulated banks to maintain a
minimum risk-based total capital ratio equal to 8 percent, of which at least 4
percent must be Tier 1 capital. Tier 1 capital includes common shareholders'
equity, qualifying perpetual preferred stock and minority interests in equity
accounts of consolidated subsidiaries, but excludes goodwill and most other
intangibles and the allowance for loan and lease losses. Tier 2 capital includes
the excess of any preferred stock not included in Tier 1 capital, mandatory
convertible securities, hybrid capital instruments, subordinated debt and
intermediate term preferred stock, and general reserve for loan and lease losses
up to 1.25 percent of risk weighted assets. West Bank has not received any
notice indicating that it will be subject to higher capital requirements.

Under these guidelines, bank assets are given risk weights of 0 percent, 20
percent, 50 percent or 100 percent. Most loans are assigned to the 100 percent
risk category, except first mortgage loans fully secured by residential property
and, under certain circumstances, residential construction loans (both carry a
50 percent rating). Most investment securities are assigned to the 20 percent
category, except for municipal or state revenue bonds (which have a 50 percent
rating) and direct obligations of or obligations guaranteed by the United States
Treasury or United States government agencies (which have a 0 percent rating).

The Agencies have also implemented a leverage ratio, which is equal to Tier 1
capital as a percentage of average total assets less intangibles, to be used as
a supplement to the risk based guidelines. The principal objective of the
leverage ratio is to limit the maximum degree to which a bank may leverage its
equity capital base. The minimum required leverage ratio for top rated
institutions is 3 percent, but most institutions are required to maintain an
additional cushion of at least 100 to 200 basis points. Any institution
operating at or near the 3 percent level is expected to be a strong banking
organization without any supervisory, financial, or operational weaknesses or
deficiencies. Any institution experiencing or anticipating significant growth
would be expected to maintain capital ratios, including tangible capital
positions, well above the minimum levels.

Prompt Corrective Action. Regulations adopted by the Agencies impose even more
stringent capital requirements. The FDIC and other Agencies must take certain
"prompt corrective action" when a bank fails to meet capital requirements. The
regulations establish and define five capital levels: (1) "well-capitalized",
(2) "adequately capitalized", (3) "undercapitalized", (4) "significantly
undercapitalized", and (5) "critically undercapitalized". Increasingly severe
restrictions are imposed on the payment of dividends and management fees, asset
growth and other aspects of the operations of institutions that fall below the
category of being "adequately capitalized". Undercapitalized institutions are
required to develop and implement capital plans acceptable to the appropriate
federal regulatory agency. Such plans must require that any company that
controls the undercapitalized institution must provide certain guarantees that
the institution will comply with the plan until it is adequately capitalized. As
of the date of this Annual Report on Form 10-K, neither the Company nor West
Bank was subject to any regulatory order, agreement, or directive to meet and
maintain a specific capital level for any capital measure. Furthermore, as of
that same date, West Bank was categorized as "well-capitalized" under regulatory
prompt corrective action provisions.

Restrictions on Dividends. Dividends paid to the Company by West Bank are the
major source of Company cash flow. Various federal and state statutory
provisions limit the amount of dividends banking subsidiaries are permitted to
pay to their holding companies without regulatory approval. Federal Reserve
policy further limits the circumstances under which bank holding companies may
declare dividends. For example, a bank holding company should not continue its
existing rate of cash dividends on its common stock unless its net income is
sufficient to fully fund each dividend and its prospective rate of earnings
retention appears consistent with its capital needs, asset quality, and overall
financial condition. In addition, the Federal Reserve and the FDIC have issued
policy statements providing that insured banks and bank holding companies should
generally pay dividends only out of current operating earnings. Federal and
state banking regulators may also restrict the payment of dividends by order.

                                       10
<PAGE>

West Bank, as a state chartered bank, is restricted under Iowa law to paying
dividends only out of its undivided profits. Additionally, the payment of
dividends by West Bank is affected by the requirement to maintain adequate
capital pursuant to applicable capital adequacy guidelines and regulations, and
West Bank is generally prohibited from paying any dividends if, following
payment thereof, the bank would be undercapitalized. As of December 31, 2005,
approximately $2.5 million was available to be paid as dividends by West Bank to
the Company without prior regulatory approval.

Reserves Against Deposits. The Federal Reserve requires all depository
institutions to maintain reserves against their transaction accounts (primarily
checking accounts) and non-personal time deposits. Generally, reserves of 3
percent must be maintained against total transaction accounts of $48,300,000 or
less (subject to an exemption not in excess of the first $7,800,000 of
transaction accounts). A reserve of $1,215,000 plus 10 percent of amounts in
excess of $48,300,000 must be maintained in the event total transaction accounts
exceed $48,300,000. The balances maintained to meet the reserve requirements
imposed by the Federal Reserve may be used to satisfy applicable liquidity
requirements. Because required reserves must be maintained in the form of vault
cash or a non-interest bearing account at a Federal Reserve Bank, the effect of
this reserve requirement is to reduce the earning assets of West Bank.

Bank Offices. Iowa laws regulating the establishment of bank offices were
changed in 2004 to provide the Company with more flexibility in establishing
additional offices of West Bank. Effective July 1, 2004, the geographical
restrictions on bank office locations were repealed. Also effective July 1,
2004, Iowa law restricting the ability of a bank to establish a de novo office
within the limits of a municipal corporation where there was already an
established state or national bank or bank office was repealed.

Nonbanking Subsidiaries

VMF Capital and IMG are under the jurisdiction of the Investment Advisors Act of
1940 and are regulated by the Securities and Exchange Commission ("SEC"). Both
companies have filed Form ADV with the SEC. Investment advisers are heavily
regulated by the SEC. The SEC has recently promulgated several proposed as well
as final rules pertaining to corporate governance and compliance matters with
which VMF Capital and IMG will be required to comply.

Regulatory Developments

In 1999, the Financial Services Modernization Act was enacted which: (1)
repealed historical restrictions on preventing banks from affiliating with
securities firms; (2) broadened the activities that may be conducted by bank
subsidiaries of holding companies; and (3) provided an enhanced framework for
protecting the privacy of consumers' information. In addition, bank holding
companies may be owned, controlled or acquired by any company engaged in
financially related activities, as long as such company meets regulatory
requirements. To the extent that this legislation permits banks to affiliate
with financial services companies, the banking industry may experience further
consolidation, although the impact of this legislation on the Company and West
Bank is unknown.

In 2001, the USA Patriot Act of 2001 was enacted in response to the September
11, 2001, terrorist attacks in New York, Pennsylvania and Washington, D.C. The
Patriot Act is intended to strengthen U.S. law enforcements' and the
intelligence communities' abilities to work together to combat terrorism. The
Patriot Act contains, among other things, anti-money laundering and financial
transparency laws and imposes various regulations, including standards for
verifying client identification at account opening, and rules to promote
cooperation among financial institutions, regulators and law enforcement in
identifying parties that may be involved in terrorism or money laundering.
Included in the Patriot Act are requirements for financial institutions to
establish anti-money laundering programs that include: (1) internal policies,
procedures and controls; (2) designation of an anti-money laundering compliance
officer; (3) ongoing employee training programs; and (4) an independent audit
function to test the anti-money laundering program. The Bank's policies and
procedures have been updated to meet the requirements of the USA Patriot Act.

On February 8, 2006, the Budget Reconciliation Bill, which contained deposit
insurance reform provisions, was signed into law. Under the legislation, the
Bank Insurance Fund and the Savings Association Insurance Fund will be merged;
the $100,000 of depositor insurance limitation will be indexed to inflation,
would be increased to $250,000 for retirement accounts, and will be subject to
increase every five years. In addition the Bill eliminates the existing trigger
for increases of deposit insurance premiums, and in its place the FDIC will be
able to set the fund's reserve ratio in a range between 1.15 and 1.50 percent of
insured deposits. The provisions of the Bill require that final regulations be
issued no later than 270 days after enactment of the law, and have an effective
date not later than 90 days following publication of the rules in the Federal
Register.

Regulatory Enforcement Authority

The enforcement powers available to federal and state banking regulators are
substantial and include, among other things, the ability to assess civil
monetary penalties, to issue cease-and-desist or removal orders and to initiate
injunctive actions against banking organizations and institution-affiliated
parties, as defined. In general, enforcement actions must be initiated for
violations of laws and regulations and unsafe or unsound practices. Other
actions, or inactions, may provide the basis for enforcement action, including
misleading or untimely reports filed with regulatory authorities. Applicable law
also requires public disclosure on final enforcement actions by the federal
banking agencies.

National Monetary Policies

In addition to being affected by general economic conditions, the earnings and
growth of West Bank are affected by the regulatory authorities' policies,
including the Federal Reserve. An important function of the Federal Reserve is
to regulate the money supply, credit conditions, and interest rates. Among the
instruments used to implement these objectives are open market operations in
U.S. Government securities, changes in reserve requirements against bank
deposits, and the Federal Reserve Discount Rate, which is the rate charged banks
borrowing from the Federal Reserve Bank. These instruments are used in varying
combinations to influence overall growth and distribution of credit, bank loans,
investments, and deposits, and their use may also affect interest rates charged
on loans or paid on deposits.

The monetary policies of the Federal Reserve have had a material impact on the
operating results of commercial banks in the past and are expected to do so in
the future.

ITEM 1A. RISK FACTORS

West Bancorporation's business is conducted through its three wholly owned
subsidiaries: West Bank, VMF Capital and IMG. In 2005, West Bank generated over
98% of West Bancorporation's net income. The most substantial risks for the
Company's stock, therefore, involve West Bank. The largest component of West
Bank's 2005 income was interest received on loans. The next largest component
was interest paid to West Bank on investment securities, Federal funds, and
short-term investments. The Company believes the following are the most
significant risk factors for the next year. West Bancorporation is also subject
to other risks, both known and unknown. The reader, therefore, should consider
all other information contained in this Form 10-K and in the Appendix to our
Proxy Statement, which was filed on March 7, 2006. All of that information is
incorporated herein by this reference.

West Bank Loan Portfolio

At December 31, 2005, West Bank's loan portfolio included $753,975,000 of
commercial real estate loans, commercial lines of credit, commercial term loans,
and construction or land development loans. These loans made up 86.8 percent of
the bank's entire loan portfolio. These types of loans typically have greater
credit risks than one- to four-family residential mortgages or consumer loans
because repayment depends in significant part on the successful business
operations of the borrowers. Our commercial loans also typically include larger
loan balances to single borrowers or groups of related borrowers than do
residential mortgages or consumer loans. In addition, commercial real estate,
construction, and real estate development loans may be more negatively affected
than residential mortgage loans by adverse developments in the real estate
markets or the general economy. If the economy turns downward, commercial
borrowers may not be able to repay their loans and the value of their collateral
may decrease. Commercial loans also involve some additional risk because they
generally are not fully repaid over the loan period and usually require a large
payoff at maturity. A borrower's ability to make the maturity payment typically
depends on being able to either refinance the loan or make timely and profitable
sales of the underlying property or business collateral. The typical West Bank
borrower is a small or medium sized privately-owned business that usually has
fewer resources and less ability to sustain losses over time than larger or
publicly-owned businesses. In addition, collateral securing small business loans
may be more likely to depreciate over time or be difficult to liquidate. The
review and monitoring process by West Bank's directors, officers and staff
cannot avoid all these risks.

West Bank's management makes various business assumptions and judgments about
the collectibility of all of its loans. Despite its underwriting and review
policies, West Bank may experience loan losses that could have a material
adverse effect on its profits. If West Bank's current allowance for loan losses
is found to be insufficient to cover actual loan losses, an increase in the
allowance would be necessary. West Bank may need to significantly increase the
provision for loan losses if one or more large loans become delinquent or if the
percentage of its commercial real estate, construction, land development, and
commercial loans continues to grow. In addition, West Bank's regulators
periodically review the loan portfolio and may require increases in its
provision for loan losses or loan charge-offs. Increases in the bank's allowance
for loan losses would decrease West Bank's net income. West Bank's management
cannot be sure that it's monitoring procedures and policies will successfully
avoid certain lending risks or that West Bank's present allowance for loan
losses will be adequate to cover actual future losses.

                                       12
<PAGE>

Unlike regional and national banks that are more geographically diversified,
West Bank provides banking and financial services to customers primarily in the
Des Moines and Iowa City, Iowa, metropolitan areas. The local economic
conditions in the market areas we serve have a significant impact on the type of
loans underwritten by West Bank, the ability of the borrowers to repay these
loans, and the value of the collateral securing these loans. A significant
decline in general economic conditions in our limited market areas caused by
factors beyond West Bank's control could affect the local economic conditions
and adversely affect West Bancorporation's financial condition and profits.

Interest rates

West Bancorporation's net income is also affected by interest rate risks.
Interest rate risks are the possibilities that changes in market interest rates
may adversely affect West Bank's earnings and capital. Increases or decreases in
interest rates and the relationship between long-term and short-term rates are
both factors of interest rate risks.

Net interest income is the largest component of the Company's net income. Net
interest income is the difference between interest earned (income) and interest
paid (expense). Interest is earned on loans made to customers and on investment
securities in the investment portfolio. Interest is paid on customers' deposit
accounts and funds borrowed from other sources. The amounts of interest earned
and interest paid are the result of interest rates and the dollar balances of
loans, investments, deposits and borrowings outstanding.

Interest rates on loans and investments may not change at the same time and in
the same magnitude as interest rates on deposits and borrowings. Various factors
affect the interest rates associated with loans and investments, such as the
credit rating of the borrower and the term of the loan or investment. Generally
the longer the term of the loan or investment, the higher the interest rate.
Interest rates on investment securities are generally fixed for the term of the
investment. Interest rates on loans can be fixed for the term of the loan or
variable and change when there is a change in an associated index, such as the
prime rate. Interest rates on deposit accounts such as savings and money market
accounts generally change over time based upon changes in market interest rates.
Interest rates on certificates of deposit are usually fixed for the term of the
certificate. Interest rates associated with borrowings can be either fixed or
variable.

Net interest income is also affected by the volume of loans, investments,
deposits and borrowings that are maturing, the dollar amounts of new loan and
deposit accounts being opened, and the amounts of early loan payoffs for any
given period. These events affect the amount of dollars that may be reinvested
as interest rates change.

Interest rates associated with loans, investments, deposits and borrowings
seldom move at the same time or in the same magnitude. The ultimate impact on
net interest income over time will depend upon the direction and significance of
changes in market interest rates as well as the dollar amounts of loans,
investments, deposits and borrowings subject to the changes in market interest
rates.

ITEM 1B. UNRESOLVED STAFF COMMENTS

The registrant has no information to be disclosed under this item.

ITEM 2. PROPERTIES

The Company's office is housed in the main office of West Bank located at 1601
22nd Street in West Des Moines, Iowa. The space is leased and consists of
approximately 1,700 square feet with annual rent of $21,000. West Bank's main
office is also located in the leased facility at 1601 22nd Street in West Des
Moines. The Bank rents approximately 18,600 square feet and pays annual rent of
approximately $404,000 for a full-service banking location that includes
drive-up facilities and one automated teller machine. The bank also leases
buildings and space for six other locations located within the Des Moines
metropolitan area and one location in the Iowa City metropolitan area. These
offices are full-service banking locations, with five of these offices having
drive-up facilities and all six locations having automated teller machines.
Annual lease payments for these seven offices total approximately $462,000. The
Bank owns one other full-service banking location in Des Moines and two full
service banking locations in Iowa City. These locations also include drive-up
facilities and automatic teller machines.

VMF Capital has leased offices in Clive and Cedar Rapids, Iowa. Annual lease
payments for these offices totaled approximately $108,000 for the year ended
December 31, 2005. IMG occupies leased office space in West Des Moines, Iowa.
Annual lease payments for 2006 will total approximately $396,000 for this
facility. In February 2006, the Clive office of VMF Capital relocated to the IMG
location in West Des Moines. A search is underway to sublease the Clive office
space.

ITEM 3. LEGAL PROCEEDINGS

West Bank from time to time is a party to various legal actions arising in the
normal course of business. The Company believes that there is no threatened or
pending proceeding against the Company, West Bank, VMF Capital or IMG, which, if
determined adversely, would have a material adverse effect on the business or
financial position of the Company, West Bank, VMF Capital, or IMG.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

There were no matters submitted to a vote of security holders, through the
solicitation of proxies or otherwise, during the fourth quarter of the fiscal
year covered by this report.

                                     PART II

ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND
ISSUER PURCHASERS OF EQUITY SECURITIES

The information appearing on page 64 of the Corporation's Appendix to the Proxy
Statement, which was filed on March 7, 2006, is incorporated herein by
reference.

There were 313 holders of record of the Company's no par value common stock as
of February 16, 2006, and an estimated 800 additional beneficial holders whose
stock was held in street name by brokerage houses. The closing price of the
Company's common stock was $19.02 on February 16, 2006.

In April 2005, the Company's Board of Directors authorized the buy-back of the
Company's common stock for a period of twelve months, in an amount not to exceed
$5 million. Since that authorization, no shares have been purchased.

In April 2005, shareholders approved the West Bancorporation, Inc. Restricted
Stock Compensation Plan. The plan provides awards to be made until March 1,
2015, with a maximum of 300,000 shares purchased in the open market to be issued
as awards, subject to certain restrictions. The Compensation Committee of the
Company's Board of Directors administers the Plan. As of December 31, 2005, no
awards had been granted.

The Company increased dividends to common shareholders in 2005 to $.64 per
share, a 2.4 percent increase over $.625 for 2004 (adjusted for the 5 percent
common stock dividend). Dividend declarations are evaluated and determined by
the Board of Directors on a quarterly basis. The ability of the Company to
continue to pay such dividends will depend primarily upon the earnings of West
Bank and its ability to pay dividends to the Company. It is anticipated the
Company will continue to pay dividends on a regular basis in the future.

The ability of West Bank to pay dividends is governed by various statutes. West
Bank, as a state bank, is restricted to paying dividends only out of undivided
profits. These statutes provide that no bank shall declare or pay any dividends
in an amount greater than its retained earnings, without approval from governing
regulatory bodies. In addition, applicable bank regulatory authorities have the
power to require any bank to suspend the payment of any and all dividends until
the bank shall have complied with all requirements that may have been imposed by
such authorities.

ITEM 9A. CONTROLS AND PROCEDURES

As of the end of the period covered by this report, an evaluation was performed
under the supervision and with the participation of the Company's Chief
Executive Officer and Chief Financial Officer of the effectiveness of the
Company's disclosure controls and procedures (as defined in Exchange Act Rule
240.13a-15(e)). Based on that evaluation, the Chief Executive Officer and the
Chief Financial Officer have concluded that the Company's current disclosure
controls and procedures are effective to ensure that information required to be
disclosed by the Company in the reports that it files or submits under the
Securities Exchange Act of 1934 is recorded, processed, summarized and reported,
within the time periods specified in the Securities and Exchange Commission's
rules and forms.

Management's annual report on internal control over financial reporting appears
on page 29 of the Company's Appendix to the Proxy Statement, which was filed on
March 7, 2006, and is incorporated herein by reference.

The attestation report of the Company's registered public accounting firm on
