                                     PART I

ITEM 1.           BUSINESS

THE COMPANY

         Mercantile Bank Corporation is a registered bank holding company under
the Bank Holding Company Act of 1956, as amended (the "Bank Holding Company
Act"). Unless the text clearly suggests otherwise, references to "us," "we,"
"our," or "the company" include Mercantile Bank Corporation and its wholly-owned
subsidiaries. As a bank holding company, we are subject to regulation by the
Board of Governors of the Federal Reserve System (the "Federal Reserve Board").
We were organized on July 15, 1997, under the laws of the State of Michigan,
primarily for the purpose of holding all of the stock of Mercantile Bank of West
Michigan ("our bank"), and of such other subsidiaries as we may acquire or
establish. Our bank commenced business on December 15, 1997.

         MBWM Capital Trust I ("the trust"), a business trust subsidiary, was
formed in September 1999. Mercantile Bank Mortgage Company initiated business in
October 2000 as a subsidiary of our bank, and was reorganized as Mercantile Bank
Mortgage Company, LLC ("our mortgage company"), on January 1, 2004. On February
7, 2002, Mercantile BIDCO, Inc. ("our BIDCO"), a subsidiary of our bank, was
granted a license by the Michigan Office of Financial and Insurance Services to
operate as a Michigan Business and Industrial Development Company under the
Michigan BIDCO Act of 1986. Mercantile Insurance Center, Inc. ("our insurance
company"), a subsidiary of our bank, commenced operations during 2002 to offer
insurance products. Mercantile Bank Real Estate Co., L.L.C., ("our real estate
company"), a subsidiary of our bank, was organized on July 21, 2003, principally
to develop, construct and own a new facility to be constructed in downtown Grand
Rapids which will serve as our bank's new main office and Mercantile Bank
Corporation's headquarters.

         To date we have raised capital from our initial public offering of
common stock in October 1997, a public offering of common stock in July 1998,
issuance of cumulative preferred securities in September 1999, three private
placements of common stock during 2001, a public offering of common stock in
August 2001 and a public offering of common stock in September 2003. Our
expenses have generally been paid using the proceeds of the capital sales and
dividends from our bank. Our principal source of future operating funds is
expected to be dividends from our bank.

         We filed an election to become a financial holding company, pursuant to
the Bank Holding Company Act, as amended by Title I of the Gramm-Leach-Bliley
Act and implementing Federal Reserve Board regulations, which election became
effective March 23, 2000.

OUR BANK

         Our bank is a state banking company that operates under the laws of the
State of Michigan, pursuant to a charter issued by the Michigan Office of
Financial and Insurance Services. Our bank's deposits are insured to the maximum
extent permitted by law by the Federal Deposit Insurance Corporation ("FDIC").
Our bank's primary service area is the Kent and Ottawa County areas of West
Michigan, which includes the City of Grand Rapids, the second largest city in
the State of Michigan.

         Our bank, through its main office located at 216 North Division Avenue,
Grand Rapids, Michigan, its combination branch and retail loan center located at
4613 Alpine Avenue, Comstock Park, Michigan, its combination branch and
operations center located at 5610 Byron Center Avenue SW, Wyoming, Michigan, its
branch located at 4860 Broadmoor, Kentwood, Michigan, its branch located at 3156
Knapp Street NE, Grand Rapids, Michigan and its administration facility located
at 5650 Byron Center Avenue SW, Wyoming, Michigan, provides commercial and
retail banking services primarily to small- to medium-sized businesses based in
and around Grand Rapids. Our bank also has a loan production office located at
675 E. 16th Street, Holland, Michigan.

                                                                             2.





<PAGE>



         Our bank makes secured and unsecured commercial, construction, mortgage
and consumer loans, and accepts checking, savings and time deposits. Our bank
owns five automated teller machines ("ATM") that participate in the MAC, NYCE
and PLUS regional network systems, as well as other ATM networks throughout the
country. Our bank also enables customers to conduct certain loan and deposit
transactions by telephone and personal computer. Courier service is provided to
certain commercial customers, and safe deposit facilities are available at all
branch locations. Our bank does not have trust powers. In December 2001, our
bank entered into a joint brokerage services and marketing agreement with
Raymond James Financial Services, Inc. to make available to its customers
financial planning, retail brokerage, equity research, insurance and annuities,
retirement planning, trust services and estate planning.

THE TRUST

         In 1999 we formed the trust, a Delaware business trust. The trust's
business and affairs are conducted by its property trustee, a Delaware trust
company, and three individual administrative trustees who are employees and
officers of the company. The trust was established for the purpose of issuing
and selling its preferred securities and common securities, and used the
proceeds from the sales of those securities to acquire subordinated debentures
issued by the company. Substantially all of the net proceeds received by the
company from the transaction were contributed to our bank as capital. Additional
information regarding the trust is incorporated by reference to "Note 15 --
Subordinated Debentures" and "Note 17 -- Regulatory Matters" of the Consolidated
Financial Statements included in this Annual Report on pages F-43 through F-45.

OUR MORTGAGE COMPANY

         Our mortgage company's predecessor, Mercantile Bank Mortgage Company,
commenced operations on October 24, 2000 when our bank contributed most of its
residential mortgage loan portfolio and participation interests in certain
commercial mortgage loans to Mercantile Bank Mortgage Company. On the same date
our bank also transferred its residential mortgage origination function to
Mercantile Bank Mortgage Company. On January 1, 2004, Mercantile Bank Mortgage
Company was reorganized as Mercantile Bank Mortgage Company, LLC, a newly
established limited liability company, which is 99% owned by our bank and 1%
owned by our BIDCO. Mortgage loans originated and held by our mortgage company
are serviced by our bank pursuant to a servicing agreement.

OUR BIDCO

         Our BIDCO was granted a license by the Michigan Office of Financial and
Insurance Services on February 7, 2002, to operate our BIDCO as a Michigan
Business and Industrial Development Company. Our BIDCO, a non-depository
Michigan financial institution, offers equipment lease financing, asset based
loans, junior debt facilities and other financing where equity features may be
part of the facility pricing.

OUR INSURANCE COMPANY

         Our insurance company acquired an existing shelf insurance agency
effective April 15, 2002. An Agency and Institution Agreement was entered into
among our insurance company, our bank and Burnham Insurance Group for the
purpose of providing programs of mass marketed personal lines of insurance.
Insurance product offerings include private passenger automobile, homeowners,
personal inland marine, boat owners, recreational vehicle, dwelling fire,
umbrella policies, small business and life insurance products, all of which are
provided by and written through companies that have appointed Burnham Insurance
Group as their agent. The insurance products are marketed through a central
facility operated by the Michigan Bankers Insurance Association, members of
which include the insurance subsidiaries of various Michigan-based financial
institutions and Burnham Insurance Group. Our insurance company receives
commissions based upon written premiums produced under the Agency and
Institution Agreement.


                                                                             3.





<PAGE>



OUR REAL ESTATE COMPANY

         Our real estate company was organized on July 21, 2003, principally to
develop, construct and own a new facility to be constructed in downtown Grand
Rapids which will serve as our bank's new main office and Mercantile Bank
Corporation's headquarters. Our real estate company is 99% owned by our bank and
1% owned by our BIDCO.

EFFECT OF GOVERNMENT MONETARY POLICIES

         Our earnings are affected by domestic economic conditions and the
monetary and fiscal policies of the United States government, its agencies, and
the Federal Reserve Board. The Federal Reserve Board's monetary policies have
had, and will likely continue to have, an important impact on the operating
results of commercial banks through its power to implement national monetary
policy in order to, among other things, curb inflation or avoid a recession. The
policies of the Federal Reserve Board have a major effect upon the levels of
bank loans, investments and deposits through its open market operations in
United States government securities, and through its regulation of, among other
things, the discount rate on borrowings of member banks and the reserve
requirements against member bank deposits. Our bank maintains reserves directly
with the Federal Reserve Bank of Chicago to the extent required by law. It is
not possible to predict the nature and impact of future changes in monetary and
fiscal policies.

REGULATION AND SUPERVISION

         As a bank holding company under the Bank Holding Company Act, we are
required to file an annual report with the Federal Reserve Board and such
additional information as the Federal Reserve Board may require. We are also
subject to examination by the Federal Reserve Board.

         The Bank Holding Company Act limits the activities of bank holding
companies that have not qualified as financial holding companies to banking and
the management of banking organizations, and to certain non-banking activities.
These non-banking activities include those activities that the Federal Reserve
Board found, by order or regulation as of the day prior to enactment of the
Gramm-Leach-Bliley Act, to be so closely related to banking as to be a proper
incident to banking. These non-banking activities include, among other things:
operating a mortgage company, finance company, credit card company or factoring
company; performing certain data processing operations; providing certain
investment and financial advice; acting as an insurance agent for certain types
of credit-related insurance; leasing property on a full-payout, nonoperating
basis; and providing discount securities brokerage services for customers. With
the exception of the respective activities of our mortgage company and our BIDCO
discussed above, neither we nor any of our subsidiaries engages in any of the
foregoing non-banking activities.

         In March 2000, our election to become a financial holding company, as
permitted by the Bank Holding Company Act, as amended by Title I of the
Gramm-Leach-Bliley Act, was accepted by the Federal Reserve Board. In order to
continue as a financial holding company, we and our bank must satisfy certain
statutory requirements regarding capitalization, management, and compliance with
the Community Reinvestment Act. As a financial holding company, we are permitted
to engage in a broader range of activities than are permitted to bank holding
companies.

         Those expanded activities include any activity which the Federal
Reserve Board (in certain instances in consultation with the Department of the
Treasury) determines, by order or regulation, to be financial in nature or
incidental to such financial activity, or to be complementary to a financial
activity and not to pose a substantial risk to the safety or soundness of
depository institutions or the financial system generally. Such expanded
activities include, among others: insuring, guaranteeing, or indemnifying
against loss, harm, damage, illness, disability or death, or issuing annuities,
and acting as principal, agent, or broker for such purposes; providing
financial, investment, or economic advisory services, including advising a
mutual fund; and underwriting, dealing in, or making a market in securities.
Other than the insurance agency activities of our insurance company, neither we
nor our subsidiaries presently engage in any such expanded activity.

                                                                             4.

<PAGE>



         Our bank is subject to certain restrictions imposed by federal law and
regulation. Among other things, these restrictions apply to any extension of
credit to us or to our other subsidiaries, to investments in stock or other
securities that we issue, to the taking of such stock or securities as
collateral for loans to any borrower, and to acquisitions of assets or services
from, and sales of certain types of assets to, us or our other subsidiaries.
Federal law prevents us from borrowing from our bank unless the loans are
secured in designated amounts with specified forms of collateral.

         With respect to the acquisition of banking organizations, we are
generally required to obtain the prior approval of the Federal Reserve Board
before we can acquire all or substantially all of the assets of any bank, or
acquire ownership or control of any voting shares of any bank or bank holding
company, if, after such acquisition, we would own or control more than 5% of the
voting shares of the bank or bank holding company. Acquisitions of banking
organizations across state lines are subject to certain restrictions imposed by
Federal and state law and regulations.

EMPLOYEES

         As of December 31, 2003, we and our bank employed 139 full-time and 40
part-time persons. Management believes that relations with employees are good.

LENDING POLICY

         As a routine part of our business, we make loans and leases to
businesses and individuals located within our market area. Our lending policy
states that the function of the lending operation is twofold: to provide a means
for the investment of funds at a profitable rate of return with an acceptable
degree of risk, and to meet the credit needs of the creditworthy businesses and
individuals who are our customers. We recognize that in the normal business of
lending, some losses on loans and leases will be inevitable and should be
considered a part of the normal cost of doing business.

         Our lending policy anticipates that priorities in extending loans and
leases will be modified from time to time as interest rates, market conditions
and competitive factors change. The policy sets forth guidelines on a
nondiscriminatory basis for lending in accordance with applicable laws and
regulations. The policy describes various criteria in granting loans and leases,
including the ability to pay; the character of the customer; evidence of
financial responsibility; purpose of the loan or lease; knowledge of collateral
and its value; terms of repayment; source of repayment; payment history; and
economic conditions.

         The lending policy further limits the amount of funds that may be
loaned or leased against specified types of real estate collateral. For certain
loans secured by real estate, the policy requires an appraisal of the property
offered as collateral by a state certified independent appraiser. The policy
also provides general guidelines for loan to value and lease to value limits for
other types of collateral, such as accounts receivable and machinery and
equipment. In addition, the policy provides general guidelines as to
environmental analysis, loans to employees, executive officers and directors,
problem loan and lease identification, maintenance of an allowance for loan and
lease losses, loan and lease review and grading, mortgage and consumer lending,
and other matters relating to our lending practices.

         The Board of Directors has delegated significant lending authority to
officers of our bank. The Board of Directors believes this empowerment,
supported by our strong credit culture and the significant experience of our
commercial lending staff, makes us responsive to our customers. The loan policy
currently specifies lending authority for certain officers up to $1.0 million,
and $6.0 million for our bank's Chairman of the Board and its President and
Chief Executive Officer; however, the $6.0 million lending authority is used
only in rare circumstances where timing is of the essence. Generally, loan
requests exceeding $2.5 million require approval by the Officers Loan Committee,
and loan requests exceeding $3.0 million, up to the legal lending limit of
approximately $29.7 million, require approval by the Board of Directors. In most
circumstances we apply an in-house lending limit that is significantly less than
our bank's legal lending limit.

                                                                             5.


<PAGE>



LENDING ACTIVITY

         Commercial Loans. Our commercial lending group originates commercial
loans and leases primarily in our market area. Commercial loans and leases are
originated by 13 lenders, with almost 200 years of combined commercial lending
experience, eight of whom have 15 years or more experience. Loans and leases are
originated for general business purposes, including working capital, accounts
receivable financing, machinery and equipment acquisition, and commercial real
estate financing including new construction and land development.

         Working capital loans are often structured as a line of credit and are
reviewed periodically in connection with the borrower's year-end financial
reporting. These loans are generally secured by substantially all of the assets
of the borrower, and have an interest rate tied to the national prime rate.
Loans and leases for machinery and equipment purposes typically have a maturity
of three to five years and are fully amortizing, while commercial real estate
loans are usually written with a five-year maturity and amortized over a 15 year
period. Commercial loans and leases typically have an interest rate that is
fixed to maturity or is tied to the national prime rate.

         We evaluate many aspects of a commercial loan or lease transaction in
order to minimize credit and interest rate risk. Underwriting includes an
assessment of the management, products, markets, cash flow, capital, income and
collateral. This analysis includes a review of the borrower's historical and
projected financial results. Appraisals are generally required by certified
independent appraisers where real estate is the primary collateral, and in some
cases, where equipment is the primary collateral. In certain situations, for
creditworthy customers, we may accept title reports instead of requiring
lenders' policies of title insurance.

         Commercial real estate lending involves more risk than residential
lending because loan balances are greater and repayment is dependent upon the
borrower's business operations. We attempt to minimize the risks associated with
these transactions by generally limiting our commercial real estate lending to
owner-operated properties of well-known customers or new customers whose
businesses have an established profitable history. In many cases, risk is
further reduced by limiting the amount of credit to any one borrower to an
amount considerably less than our legal lending limit and avoiding certain types
of commercial real estate financings.

         We have no material foreign or agricultural loans, and no material
loans to energy producing customers.

         Single-Family Residential Real Estate Loans. Our mortgage company
originates single-family residential real estate loans in our market area,
usually according to secondary market underwriting standards. Loans not
conforming to those standards are made in limited circumstances. Single-family
residential real estate loans provide borrowers with a fixed or adjustable
interest rate with terms up to 30 years.

         Our bank has a home equity line of credit program. Home equity credit
is generally secured by either a first or second mortgage on the borrower's
primary residence. The program provides revolving credit at a rate tied to the
national prime rate.

         Consumer Loans. We originate consumer loans for a variety of personal
financial needs, including new and used automobiles, boat loans, credit cards
and overdraft protection for our checking account customers. Consumer loans
generally have shorter terms and higher interest rates and usually involve more
credit risk than single-family residential real estate loans because of the type
and nature of the collateral.

         While we do not utilize a formal credit scoring system, management
believes our consumer loans are underwritten carefully, with a strong emphasis
on the amount of the down payment, credit quality, employment stability and
monthly income of the borrower. These loans are generally repaid on a monthly
repayment schedule with the source of repayment tied to the borrower's periodic
income. In addition, consumer lending collections are dependent on the
borrower's continuing financial stability, and are thus likely to be adversely
affected by job loss, illness and personal bankruptcy. In many cases,
repossessed collateral for a defaulted consumer loan will not provide an
adequate source of repayment of the outstanding loan balance because of
depreciation of the underlying collateral.


                                                                             6.
<PAGE>



         Management believes that the generally higher yields earned on consumer
loans compensate for the increased credit risk associated with such loans and
that consumer loans are important to our efforts to serve the credit needs of
the communities and customers that we serve.

LOAN AND LEASE PORTFOLIO QUALITY

         We utilize a comprehensive grading system for our commercial loans and
leases as well as residential mortgage and consumer loans. Administered as part
of the loan and lease review program, all commercial loans and leases are graded
on an eight grade rating system. The rating system utilizes a standardized grade
paradigm that analyzes several critical factors such as cash flow, management
and collateral coverage. All commercial loans and leases are graded at inception
and later at various intervals. Residential mortgage and consumer loans are
graded on a four grade rating system using a separate standardized grade
paradigm that analyzes several critical factors such as debt-to-income and
credit and employment histories. Residential mortgage and consumer loans are
generally only graded once after the loans are made.

         Our independent loan and leases review program is primarily responsible
for the administration of the grading system and ensuring adherence to
established lending policies and procedures. The loan and lease review program
is an integral part of maintaining our strong asset quality culture. The loan
and lease review function works closely with senior management, although it
functionally reports to the Board of Directors. All commercial loan and lease
relationships exceeding $1.0 million are formally reviewed every twelve to
eighteen months. Watch list credits are formally reviewed monthly. Credits
between $0.5 million and $1.0 million are formally reviewed every two years,
with a random sampling performed on credits under $0.5 million.

         Loans and leases are placed in a nonaccrual status when, in the opinion
of management, uncertainty exists as to the ultimate collection of principal and
interest. As of December 31, 2003, loans and leases placed in nonaccrual status
totaled $0.2 million, or 0.02% of total loans. In addition, loans and leases
past due 90 days or more and still accruing interest totaled $1.6 million, or
0.15% of total loans and leases. As of December 31, 2003, there were no other
significant loans and leases where known information about credit problems of
borrowers warranted the placing of the loans or leases in a nonaccrual status.
Management is not aware of any potential problem credits that could have a
material adverse effect on our operating results, liquidity, or capital
resources.

         Additional detail and information relative to the loan and lease
portfolio is incorporated by reference to Management's Discussion and Analysis
of Financial Condition and Results of Operation ("Management's Discussion and
Analysis") beginning on Page F-4 and Note 3 of the Consolidated Financial
Statements on pages F-33 and F-34 included in this Annual Report.

ALLOWANCE FOR LOAN AND LEASE LOSSES

         In each accounting period, the allowance for loan and lease losses
("allowance") is adjusted by management to the amount management believes is
necessary to maintain the allowance at adequate levels. Through its loan and
lease review and credit departments, management attempts to allocate specific
portions of the allowance based on specifically identifiable problem loans and
leases. Management's evaluation of the allowance is further based on, but not
limited to, consideration of internally prepared calculations based upon the
experience of senior management and lending staff making similar loans and
leases in the same community over the past 15 years, composition of the loan and
lease portfolio, third party analysis of the loan and lease administration
processes and portfolio and general economic conditions. In addition, our bank's
status as a relatively new banking organization, the rapid loan growth since
inception and commercial lending emphasis is taken into account. Management
believes that the present allowance is adequate, based on the broad range of
considerations listed above.


                                                                             7.





<PAGE>



         The primary risks associated with commercial loans and leases are the
financial condition of the borrower, the sufficiency of collateral, and lack of
timely payment. Management has a policy of requesting and reviewing periodic
financial statements from its commercial loan and lease customers, and
periodically reviews existence of collateral and its value. The primary risk
element considered by management with respect to each consumer and residential
real estate loan is lack of timely payment. Management has a reporting system
that monitors past due loans and has adopted policies to pursue its creditor's
rights in order to preserve our bank's collateral position.

         Additional detail regarding the allowance is incorporated by reference
to Management's Discussion and Analysis beginning on Page F-4 and Note 3 of the
Consolidated Financial Statements of the Company on pages F-33 and F-34 included
in this Annual Report.

         Although management believes the allowance is adequate to absorb losses
as they arise, there can be no assurance that we will not sustain losses in any
given period which could be substantial in relation to, or greater than, the
size of the allowance.

INVESTMENTS

         Our principal investments are our investment in the common stock of our
bank and the common securities of the trust. Our funds may be invested from time
to time in various debt instruments, including obligations of or guaranteed by
the United States, general obligations of a state or political subdivision or an
agency of a state or political subdivision, banker's acceptances or certificates
of deposit of United States commercial banks, or commercial paper of United
States issuers rated in the highest category by a nationally-recognized
investment rating service. We are permitted to make portfolio investments in
equity securities and to make equity investments in subsidiary corporations
engaged in certain non-banking activities which may include real estate-related
activities such as mortgage banking, community development, real estate
appraisals, arranging equity financing for commercial real estate, and owning
and operating real estate used substantially by our bank or acquired for its
future use. However, we have no present plans to make any of these equity
investments. Our Board of Directors may alter the investment policy at any time
without shareholder approval.

         Our bank may invest its funds in a wide variety of debt instruments and
may participate in the federal funds market with other depository institutions.
Subject to certain exceptions, our bank is prohibited from investing in equity
securities. Among such permitted equity investments are shares of a subsidiary
insurance agency, mortgage company, real estate company, or Michigan business
and industrial development company, such as our insurance company, our mortgage
company, our real estate company, or our BIDCO. Under another such exception, in
certain circumstances and with the prior approval of the FDIC, our bank could
invest up to 10% of its total assets in the equity securities of a subsidiary
corporation engaged in the acquisition and development of real property for
sale, or the improvement of real property by construction or rehabilitation of
residential or commercial units for sale or lease. Our bank has no present plans
to make such an investment. Real estate acquired by our bank in satisfaction of
or foreclosure upon loans may be held by our bank. Our bank is also permitted to
invest in such real estate as is necessary for the convenient transaction of its
business. Our bank's Board of Directors may alter the investment policy without
shareholder approval at any time.

         Additional detail and information relative to the securities portfolio
is incorporated by reference to Management's Discussion and Analysis beginning
at Page F-4 and Note 2 of the Consolidated Financial Statements on pages F-31
through F-33 included in this Annual Report.

COMPETITION

         Our primary market area for loans and core deposits is the Kent and
Ottawa Counties of western Michigan, which includes the City of Grand Rapids,
the second largest city in the State of Michigan. We face substantial
competition in all phases of our operations from a variety of different
competitors. We compete for deposits, loans and other financial services from
numerous Michigan-based and out-of-state banks, savings banks, thrifts, credit
unions and other financial institutions as well as from other entities that
provide financial services. Some of the financial institutions and financial
service organizations with which we compete are not subject to the same degree
of regulation as we are. Many of our primary competitors have been in business
for many years, have established customer bases, are larger, have substantially
higher lending limits than we do, and offer branch networks and other services
which we do not. Most of these same entities have greater capital resources than
we do, which, among other things, may allow them to price their services at
levels more favorable to the customer and to provide larger credit facilities
than we do. Under the Gramm-Leach-Bliley Act, effective March 11, 2000,
securities firms and insurance companies that elect to become financial holding
companies may acquire banks and other financial institutions. The
Gramm-Leach-Bliley Act may significantly change the competitive environment in
which we conduct our business. The financial services industry is also likely to
become more competitive as further technological advances enable more companies
to provide financial services.

         During 2001 our bank designed and constructed two facilities on a
4-acre parcel of land located in the City of Wyoming, a southwest suburb of
Grand Rapids. The land had been purchased by our bank in 2000. The larger of the
two buildings is a full service branch and operations facility which opened in
September of 2001. The facility is two-stories, of masonry construction, and has
approximately 25,000 square feet of usable space. The facility is owned by our
bank, and has multiple drive-through lanes and ample parking space. The address
of this facility is 5610 Byron Center Avenue SW, Wyoming, Michigan. The other
building, a single-story facility of masonry construction with approximately
7,000 square feet of usable space, accommodates the company's and bank's
administration function. This facility is also owned by the bank. The address of
this facility is 5650 Byron Center Avenue SW, Wyoming, Michigan.

         During 2002 our bank designed and constructed a full service branch in
the City of Kentwood, a southeast suburb of Grand Rapids, which opened in

bank's current downtown facility located on North Division Avenue, with all
existing functions and employees at that location ultimately transferring to
this new facility upon completion. Currently, the North Division Avenue facility
serves as our bank's main office, and houses our bank's commercial lending and
review function, a full service branch, portions of our bank's retail lending
and business development function and our bank's brokerage operation. The new
facility will also house our bank's loan operations function, which is currently
located at our facility on Alpine Avenue NW, as well as the company's and bank's
administration function currently located in Wyoming, Michigan. The facility
will consist of approximately 55,000 square feet of usable space and contain
multiple drive-through lanes with ample parking. Anticipated opening date is the
latter part of 2005. The address is 1155 Front Street NW, Grand Rapids,
Michigan.

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

       Our Common Stock is quoted on the Nasdaq National Market under the
symbol "MBWM". At February 1, 2004, there were 243 record holders of our common
stock. In addition, we estimate that there were approximately 3,000 beneficial
owners of our common stock who own their shares through brokers or banks.

       The following table shows the high and low bid prices for our common
stock as reported by the Nasdaq National Market for the periods indicated, and
the quarterly cash dividends paid by us during those periods. The prices do not
include retail mark-up, mark-down or commission, but have been adjusted for the
5% stock dividends paid on February 3, 2003, and February 1, 2002.

         Holders of our common stock are entitled to receive dividends that the
Board of Directors may declare from time to time. We may only pay dividends out
of funds that are legally available for that purpose. We are a holding company
and substantially all of our assets are held by our subsidiaries. Our ability to
pay dividends to our shareholders depends primarily on our bank's ability to pay
dividends to us. Dividend payments and extensions of credit to us from our bank
are subject to legal and regulatory limitations, generally based on capital
levels and current and retained earnings imposed by law and regulatory agencies
with authority over our bank. The ability of our bank to pay dividends is also
subject to its profitability, financial condition, capital expenditures and
other cash flow requirements. In addition, under the terms of our 9.60% junior
subordinated debentures due 2029, we would be precluded from paying dividends on
our common stock if we were in default under the debentures and did not take
reasonable steps to cure the default, if we exercised our right to defer
payments of interest on the debentures, or if certain related defaults occurred.

         On January 6, 2004, we declared a $0.09 per share cash dividend on our
common stock, payable on March 10, 2004 to record holders as of February 10,
2004. We currently expect to continue to pay a quarterly cash dividend, although
there can be no assurance that we will continue to do so.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS


FORWARD-LOOKING STATEMENTS

The following discussion contains forward-looking statements that are based on
management's beliefs, assumptions, current expectations, estimates and
projections about the financial services industry, the economy, and about our
company. Words such as "anticipates," "believes," "estimates," "expects,"
"forecasts," "intends," "is likely," "plans," "projects," variations of such
words and similar expressions are intended to identify such forward-looking
statements. These statements are not guarantees of future performance and
involve certain risks, uncertainties and assumptions ("Future Factors") that are
difficult to predict with regard to timing, extent, likelihood and degree of
occurrence. Therefore, actual results and outcomes may materially differ from
what may be expressed or forecasted in such forward-looking statements. We
undertake no obligation to update, amend, or clarify forward-looking statements,
whether as a result of new information, future events (whether anticipated or
unanticipated), or otherwise.

Future Factors include changes in interest rates and interest rate
relationships; demand for products and services; the degree of competition by
traditional and non-traditional competitors; changes in banking regulation;
changes in tax laws; changes in prices, levies, and assessments; the impact of
technological advances; governmental and regulatory policy changes; the outcomes
of contingencies; trends in customer behavior as well as their ability to repay
loans; and changes in the national and local economy. These are representative
of the Future Factors that could cause a difference between an ultimate actual
outcome and a preceding forward-looking statement.



INTRODUCTION

This Management's Discussion and Analysis should be read in conjunction with the
consolidated financial statements contained herein. This discussion provides
information about the consolidated financial condition and results of operations
of Mercantile Bank Corporation and its subsidiaries, Mercantile Bank of West
Michigan ("our bank") and MBWM Capital Trust I ("the trust"), and of Mercantile
Bank Mortgage Company, LLC ("our mortgage company"), Mercantile BIDCO, Inc.
("our BIDCO"), Mercantile Bank Real Estate Co., L.L.C. ("our real estate
company") and Mercantile Insurance Center, Inc. (our insurance company"),
subsidiaries of our bank. Unless the text clearly suggests otherwise, references
to "us," "we," "our," or "the company" include Mercantile Bank Corporation and
its wholly-owned subsidiaries referred to above.

We were incorporated on July 15, 1997 as a bank holding company to establish and
own our bank. Our bank, after receiving all necessary regulatory approvals,
began operations on December 15, 1997. Our bank has a strong commitment to
community banking and offers a wide range of financial products and services,
primarily to small- to medium-sized businesses, as well as individuals. Our
bank's lending strategy focuses on commercial lending, and, to a lesser extent,
residential mortgage and consumer lending. Our bank also offers a broad array of
deposit products, including checking, savings, money market, and certificates of
deposit, as well as security repurchase agreements. Our bank's primary market
area is the Kent and Ottawa County areas of West Michigan, which includes the
City of Grand Rapids, the second largest city in the State of Michigan. Our bank
utilizes certificates of deposit from customers located outside of the primary
market area to assist in funding the rapid asset growth our bank has experienced
since inception.

The trust, a business trust subsidiary of the company, was incorporated in 1999
for the purpose of issuing 1.6 million shares of 9.60% Cumulative Preferred
Securities ("trust preferred securities") at $10.00 per trust preferred
security. The proceeds from the September 1999 sale were used by the trust to
purchase an equivalent amount of subordinated debentures of the company. The
company, in turn, used a majority of the proceeds from the issuance of the
subordinated debentures for a capital contribution to our bank. The only
significant asset of the trust is the subordinated debenture of the company and
the only significant liability of the trust is the trust preferred securities.
The trust preferred securities are carried on the company's consolidated balance
sheet as a liability and the interest expense is recorded on the company's
consolidated statement of income.

Our mortgage company's predecessor, Mercantile Bank Mortgage Company, was formed
to increase the profitability and efficiency of the company's mortgage loan
operations. Mercantile Bank Mortgage Company initiated business on October 24,
2000 from our bank's contribution of most of its residential mortgage loan
portfolio and participation interests in certain commercial mortgage loans. On
the same date our bank had also transferred its residential mortgage origination
function to Mercantile Bank Mortgage Company. On January 1, 2004, Mercantile
Bank Mortgage Company was reorganized as Mercantile Bank Mortgage Company, LLC,
a newly established limited liability company. Mortgage loans originated and
held by our mortgage company are serviced by our bank pursuant to a servicing
agreement.

On February 7, 2002 our BIDCO was granted a license by the Michigan Office of
Financial and Insurance Services to operate as a Michigan Business and
Industrial Development Company. Our BIDCO, a non-depository Michigan financial
institution, offers equipment lease financing, asset based loans, junior debt
facilities and other financing where equity features may be part of the facility
pricing.

Our insurance company acquired, at nominal cost, an existing shelf insurance
agency effective April 15, 2002. An Agency and Institution Agreement was entered
into among our insurance company, our bank and Burnham Insurance Group for the
purpose of providing programs of mass marketed personal lines of insurance.
Insurance product offerings include private passenger automobile, homeowners,
personal inland marine, boat owners, recreational vehicle, dwelling fire,
umbrella policies, small business and life insurance products, all of which are
provided by and written through companies that have appointed Burnham Insurance
Group as their agent. The insurance products are marketed through a central
facility operated by the Michigan Bankers Insurance Association, members of
which include the insurance subsidiaries of various Michigan-based financial
institutions and Burnham Insurance Group. Our insurance company receives
commissions based upon written premiums produced under the Agency and
Institution Agreement.

Our real estate company was organized on July 21, 2003, principally to develop,
construct and own a new facility to be constructed in downtown Grand Rapids
which will serve as our bank's new main office and Mercantile Bank Corporation's
headquarters.



FINANCIAL CONDITION

We continued to experience significant asset growth during 2003. Assets
increased from $921.9 million on December 31, 2002 to $1,202.8 million on
December 31, 2003. This represents an increase in total assets of $280.9
million, or 30.5%. The increase in total assets was primarily comprised of a
$260.9 million increase in net loans and a $24.6 million increase in securities.
The increase in assets was primarily funded by a $148.8 million increase in
deposits, a $75.0 million increase in Federal Home Loan Bank advances and a
$50.4 million increase in shareholder's equity.

EARNING ASSETS
Average earning assets equaled 95.2% of average total assets during 2003,
compared to 95.5% during 2002. Although we experienced significant asset growth
during 2003, the asset composition remained relatively constant. The loan
portfolio continued to comprise a majority of earning assets, followed by
securities, federal funds sold, and short-term investments.

Our loan and lease portfolio, which equaled 88.9% of average earnings assets
during 2003, is primarily comprised of commercial loans and leases. Constituting
93.9% of average loans and leases and growing by $232.9 million during 2003, the
commercial loan and lease portfolio represent loans to business interests
generally located within our market area. Approximately 67% of the commercial
loan and lease portfolio is primarily secured by real estate properties, with
the remaining generally secured by other business assets such as accounts
receivable, inventory, and equipment. The continued significant concentration of
the loan and lease portfolio in commercial loans and leases and the rapid growth
of this portion of our lending business are consistent with our strategy of
focusing a substantial amount of our efforts on "wholesale" banking. Corporate
and business lending continues to be an area of expertise for our senior
management team, and our 13 commercial lenders have almost 200 years of combined
commercial lending experience, eight of whom have 15 years or more experience.
Of each of the loan categories that we originate, commercial loans and leases
are most efficiently originated and managed, thus limiting overhead costs by
necessitating the attention of fewer full-time employees. Our commercial lending
business generates the greatest amount of local deposits and is virtually our
only source of significant demand deposits.

Residential mortgage and consumer lending, while averaging only 6.1% of average
loans during 2003, also experienced excellent growth; however, while we expect
the residential mortgage loan and consumer loan portfolios to increase in future
periods, given our wholesale banking strategy, the commercial sector of the
lending efforts and resultant assets are expected to remain the dominant loan
portfolio category.

The following tables present the maturity of total loans outstanding, as of
December 31, 2003, according to scheduled repayments of principal on fixed rate
loans and repricing frequency on variable rate loans. Floating rate loans that
have reached interest rate floors are treated as fixed rate loans.

Our credit policies establish guidelines to manage credit risk and asset
quality. These guidelines include loan review and early identification of
problem loans to provide effective loan portfolio administration. The credit
policies and procedures are meant to minimize the risk and uncertainties
inherent in lending. In following these policies and procedures, we must rely on
estimates, appraisals and evaluations of loans and the possibility that changes
in these could occur quickly because of changing economic conditions. Identified
problem loans, which exhibit characteristics (financial or otherwise) that could
cause the loans to become nonperforming or require restructuring in the future,
are included on the internal "Watch List." Senior management reviews this list
regularly.

The quality of our loan portfolio remains strong, with past due loans and net
loan charge-offs well below banking industry averages during 2003. As of
December 31, 2003, past due loans and nonaccrual loans and leases totaled $1.8
million, or 0.17% of total loans and leases. At December 31, 2002, past due and
nonaccrual loans totaled $0.8 million, or 0.10% of total loans. Net loan and
lease charge-offs during 2003 totaled $311,000, or 0.04% of average total loans
and leases. During 2002 net loan and lease charge-offs totaled $606,000, or
0.09% of average total loans and leases. Over 98% of the loan portfolio consists
of loans extended directly to companies and individuals doing business and
residing within our market area. The remaining portion is comprised of
commercial loans participated with certain unaffiliated commercial banks outside
the immediate area, which are underwritten using the same loan criteria as
though our bank was the originating bank.

The following table summarizes changes in the allowance for loan and lease
losses.

In each accounting period the allowance for loan and lease losses ("allowance")
is adjusted to the amount believed necessary to maintain the allowance at
adequate levels. Through the loan review and credit departments, we attempt to
allocate specific portions of the allowance based on specifically identifiable
problem loans and leases. The evaluation of the allowance is further based on,
although not limited to, consideration of the internally prepared Loan Loss
Reserve Analysis ("Reserve Analysis"), composition of the loan and lease
portfolio, third party analysis of the loan and lease administration processes
and portfolio and general economic conditions. In addition, the rapid commercial
loan and lease growth is taken into account.

The Reserve Analysis, used since the inception of our bank and completed
monthly, applies reserve allocation factors to outstanding loan and lease
balances to calculate an overall allowance dollar amount. For commercial loans
and leases, which continue to comprise a vast majority of our total loans,
reserve allocation factors are based upon the loan ratings as determined by our
loan rating paradigm that is administered by our loan review function. For
retail loans, reserve allocation factors are based upon the type of credit.
Adjustments for specific loan relationships, including impaired loans, are made
on a case-by-case basis. The reserve allocation factors are primarily based on
the experience of senior management making similar loans in the same community
for over 15 years. The Reserve Analysis is reviewed regularly by senior
management and the Board of Directors and is adjusted periodically based upon
identifiable trends and experience.

The following table illustrates the breakdown of the allowance balance to loan
type (dollars in thousands).

The primary risk elements with respect to commercial loans and leases are the
financial condition of the borrower, the sufficiency of collateral, and lack of
timely payment. We have a policy of requesting and reviewing periodic financial
statements from commercial loan and lease customers, and we periodically review
the existence of collateral and its value. The primary risk element with respect
to each installment and residential real estate loan is lack of timely payment.
We have a reporting system that monitors past due loans and have adopted
policies to pursue creditor's rights in order to preserve our bank's position.

Although we believe that the allowance is adequate to sustain losses as they
arise, there can be no assurance that our bank will not sustain losses in any
given period that could be substantial in relation to, or greater than, the size
of the allowance.

The securities portfolio also experienced significant growth during 2003,
increasing from $96.9 million on December 31, 2002 to $121.5 million at December
31, 2003. During 2003, the securities portfolio equaled 10.1% of average earning
assets. We maintain the portfolio at levels to provide adequate pledging for the
repurchase agreement program and secondary liquidity for our daily operations.
In addition, the portfolio serves a primary interest rate risk management
function. At December 31, 2003, the portfolio was comprised of high credit
quality municipal general obligation and revenue bonds (37%), U.S. Government
Agency issued and guaranteed mortgage-backed securities (31%), U.S. Government
Agency issued bonds (28%) and Federal Home Loan Bank stock (4%).

All securities, with the exception of tax-exempt municipal bonds, have been
designated as "available for sale" as defined in Financial Accounting Standards
Board Standard (SFAS) No. 115, Accounting for Certain Investments in Debt and
Equity Securities. Securities designated as available for sale are stated at
fair value, with the unrealized gains and losses, net of income tax, reported as
a separate component of shareholders' equity in accumulated other comprehensive
income. The fair value of securities designated as available for sale at
December 31, 2003 and 2002 was $71.4 million and $59.6 million, respectively.
The net unrealized gain recorded at December 31, 2003 and 2002, was $0.3 million
and $1.6 million, respectively. All tax-exempt municipal bonds have been
designated as "held to maturity" as defined in SFAS No. 115, and are stated at
amortized cost. As of December 31, 2003 and 2002, held to maturity securities
had an amortized cost of $45.1 million and $36.5 million and a fair value of
$47.1 million and $38.0 million, respectively.

</TABLE>


(1) Yields on tax-exempt securities are computed on a fully taxable-equivalent
    basis.

Federal funds sold, consisting of excess funds sold overnight to correspondent
banks, are used to manage daily liquidity needs and interest rate sensitivity.
During 2003, the average balance of these funds equaled 0.5% of average earning
assets. This level is well within our internal policy guidelines and is not
expected to change significantly in the future.

Cash and cash equivalents declined from $28.1 million at December 31, 2002, to
$16.6 million on December 31, 2003, a decrease of $11.5 million. The decrease
was primarily the result of a federal funds purchased position of $6.0 million
at December 31, 2003 compared to a federal funds sold position of $4.5 million
on December 31, 2002, and a smaller than average outgoing cash letter on the
last day of 2003. In general, our commercial lending and wholesale funding focus
results in relatively large day-to-day fluctuations of our cash and cash
equivalent balances. The average balance of cash and cash equivalents during
2003 equaled $28.7 million.

Net premises and equipment increased from $12.2 million at December 31, 2002, to
$15.3 million on December 31, 2003, an increase of $3.1 million. The increase
primarily reflects the land purchase and initial design and construction costs
associated with our planned new main office in downtown Grand Rapids and our new
banking facility in Holland.

SOURCE OF FUNDS
Our major source of funds is from deposits and Federal Home Loan Bank ("FHLB")
advances. Total deposits increased from $754.1 million at December 31, 2002, to
$902.9 million on December 31, 2003, an increase of $148.8 million, or 19.7%.
Included within these numbers is the success we achieved in generating deposit
growth from customers located within the market area during 2003. Local deposits
increased from $241.6 million at December 31, 2002, to $311.3 million on
December 31, 2003, an increase of $69.7 million, or 28.8. Despite this success
in obtaining funds from local customers, the substantial asset growth has
necessitated the continued acquisition of funds from depositors outside of the
market area and FHLB advances. Out-of-area deposits increased from $512.5
million at December 31, 2002, to $591.6 million on December 31, 2003, an
increase of $79.1 million, or 15.4%. FHLB advances increased from $15.0 million
at December 31, 2002, to $90.0 million on December 31, 2003, an increase of
$75.0 million. At December 31, 2003, local deposits and securities sold under
agreements to repurchase ("repurchase agreements") equaled 34.4% of funding
liabilities, compared to 35.6% on December 31, 2002.

During 2003 we experienced significant growth in our check-writing deposit
accounts, which include noninterest-bearing demand accounts, interest-bearing
checking accounts and money market deposit accounts. In aggregate these deposit
types grew $20.0 million, or 20.2%. Leading the growth were noninterest-bearing
demand accounts. Comprised primarily of business loan customers,
noninterest-bearing demand accounts grew $14.2 million, or 22.7%, and equaled
6.6% of average total liabilities during 2003. Interest-bearing checking
accounts increased $6.1 million, or 21.7%, and equaled 3.0% of average total
liabilities during 2003. Money market deposit accounts decreased $0.3 million,
or 3.5%, and equaled 0.9% of average total liabilities during 2003. Business
loan customers also comprise the majority of interest-bearing checking and money
market deposit accounts, although to a lesser extent than noninterest-bearing
checking accounts. Pursuant to Federal law and regulations, incorporated
businesses may not own interest-bearing checking accounts and transactions from
money market accounts are limited. We anticipate continued growth of our
check-writing deposit accounts as additional business loans are extended and
through the efforts of our branch network and business development activities.

During 2003, savings account balances recorded an increase of $32.2 million, or
46.4%, and equaled 12.1% of average total liabilities. Business loan customers
also comprise the majority of savings account holders, although to a lesser
extent than check-writing accounts. We anticipate an increase in savings account
balances as additional business loans are extended and through the efforts of
our branch network and business development activities.

Certificates of deposit purchased by customers located within the market area
increased during 2003, growing from $73.0 million at December 31, 2002, to $90.5
million on December 31, 2003, a growth rate of 24.0%. These deposits accounted
for 9.8% of average total liabilities during 2003. The growth was primarily
attributable to individuals and municipalities. The increase in local
municipality certificates of deposit has been facilitated by our qualifying for
funds from new municipal customers and additional funds from existing customers
through a combination of our asset growth and increased profitability as
measured by the municipalities' investment policy guidelines, and is a trend
that we expect to continue.

During 2003 certificates of deposit obtained from customers located outside of
the market area increased by $79.1 million, and represented 58.5% of average
total liabilities during 2003. At December 31, 2003, out-of-area deposits
totaled $591.6 million. Out-of-area deposits consist primarily of certificates
of deposit placed by deposit brokers for a fee, but also include certificates of
deposit obtained from the deposit owners directly. The owners of the out-of-area
deposits include individuals, businesses and governmental units located
throughout the country. Out-of-area deposits are utilized to support our asset
growth, and are generally a lower cost source of funds when compared to the
interest rates that would have to be offered in the local market to generate a
sufficient level of funds. During most of 2003 rates paid on new out-of-area
deposits were very similar to rates paid on new certificates of deposit issued
to local customers. In addition, the overhead costs associated with the
out-of-area deposits are considerably less than the overhead costs that would be
incurred to administer a similar level of local deposits. Although local
deposits have and are expected to increase as new business, governmental and
consumer deposit relationships are established and as existing customers
increase the balances in their deposit accounts, the relatively high reliance on
out-of-area deposits will likely remain.

Repurchase agreements decreased $0.8 million and equaled 4.8% of average total
liabilities during 2003. As part of our sweep account program, collected funds
from certain business noninterest-bearing checking accounts are invested in
overnight interest-bearing repurchase agreements. Although not considered a
deposit account and therefore not afforded federal deposit insurance, the
repurchase agreements have characteristics very similar to that of an
interest-bearing checking deposit account.

FHLB advances increased $75.0 million and equaled 4.9% of average total
liabilities during 2003. FHLB advances are collateralized by residential
mortgage loans, first mortgage liens on multi-family residential property loans,
first mortgage liens on commercial real estate property loans, and substantially
all other assets of our bank, under a blanket lien arrangement. Our borrowing
line of credit at December 31, 2003 totaled $156.8 million. We first started to
use FHLB advances in late 2002, and expect to continue to use this funding
source, along with out-of-area certificates of deposit, as part of our wholesale
funding program.

Shareholders' equity increased $50.4 million and equaled 9.0% of average assets
during 2003. The increase was primarily attributable to the sale of common stock
and net income from operations. In October we completed the sale of 1,374,606
shares of common stock through a public offering, raising $42.8 million net of
issuance costs. Net income from operations totaled $10.0 million during 2003.
Negatively impacting shareholders' equity during 2003 was the payment of cash
dividends, which totaled $1.8 million. Shareholders' equity was also negatively
impacted by a $0.8 million mark-to-market adjustment for available for sale
securities as defined in SFAS No. 115, resulting from the changing interest rate
environment during 2003.

RESULTS OF OPERATIONS
FOR THE YEARS ENDED DECEMBER 31, 2003 and 2002

SUMMARY
We recorded strong earnings performance during 2003. Net income was $10.0
million, or $1.73 per basic share and $1.69 per diluted share. This earnings
performance compares very favorably to net income of $7.8 million, or $1.43 per
basic share and $1.41 per diluted share, recorded in 2002. The $2.2 million
improvement in net income represents an increase of 29.1%, while diluted
earnings per share were up 19.9%, with the difference primarily reflecting the
impact of our common stock sale during 2003 and resulting increases in average
common shares outstanding. The earnings improvement during 2003 over that of
2002 is primarily attributable to increased net interest income and improved
operating efficiencies resulting from asset growth, strong credit culture,
controlled overhead expenses and increased fee income. We expect our percentage
rate of loan growth to exceed the banking industry average in 2004.

The following table shows some of the key performance and equity ratios for the
years ended December 31, 2003 and 2002.

NET INTEREST INCOME
Net interest income, the difference between revenue generated from earning
assets and the interest cost of funding those assets, is our primary source of
earnings. Interest income (adjusted for tax-exempt income) and interest expense
totaled $55.4 million and $23.3 million during 2003, respectively, providing for
net interest income of $32.1 million. This performance compares favorably to
that of 2002 when interest income and interest expense were $48.2 million and
$23.9 million, respectively, providing for net interest income of $24.3 million.
In comparing 2003 with 2002, interest income increased 15.0%, interest expense
was down 2.6% and net interest income increased 32.4%. The level of net interest
income is primarily a function of asset size, as the weighted average interest
rate received on earning assets is greater than the weighted average interest
cost of funding sources; however, factors such as types of assets and
liabilities, interest rate risk, common stock sales, liquidity, and customer
behavior also impact net interest income as well as the net interest margin. The
net interest margin improved slightly from 3.19% in 2002 to 3.22% in 2003, an
increase of 0.9%.

The following table depicts the average balance, interest earned and paid, and
weighted average rate of our assets, liabilities and shareholders' equity during
2003, 2002 and 2001 (dollars in thousands). The table also depicts the dollar
amount of change in interest income and interest expense of interest-earning
assets and interest-bearing liabilities, segregated between change due to volume
and change due to rate. For tax-exempt investment securities interest income and
yield have been computed on a tax equivalent basis using a marginal tax rate of
34%.

Interest income is primarily generated from the loan portfolio, and to a lesser
degree from securities, federal funds sold and short term investments. Interest
income increased $7.2 million during 2003 from that earned in 2002, totaling
$55.4 million in 2003 compared to $48.2 million in the previous year. The
increase is due to the growth in earning assets, which more than offset the
impact of a lower interest rate environment in 2003. Reflecting the lower
interest rates, the yield on average earning assets decreased from 6.34%
recorded in 2002 to 5.55% in 2003.

The growth in interest income is attributable to an increase in earning assets.
During 2003, earning assets averaged $998.6 million, a level substantially
higher than the average earning assets of $761.3 million during 2002. Growth in
average total loans and leases, totaling $217.7 million, comprised 91.7% of the
increase in average earnings assets. Interest income generated from the loan and
lease portfolio increased $6.7 million during 2003 over the level earned in
2002, comprised of an increase of $12.7 million from the growth in the loan and
lease portfolio which was partially offset by a decrease of $6.0 million due to
the decline in the yield earned on the loan portfolio to 5.60% from 6.42%. The
decline in the loan and lease portfolio yield is primarily due to lower market
interest rates during 2003 and a higher percentage of loans and leases at the
lower floating rate pricing arrangement versus a higher fixed interest rate
arrangement.

Growth in the securities portfolio also added to the increase in interest income
during 2003 over that of 2002. Average securities increased by $22.2 million in
2003, increasing from $83.5 million in 2002 to $105.7 million in 2003. The
growth equated to an increase in interest income of $1.3 million, which was
partially offset by a decrease of $0.7 million due to the decline in the yield
earned on the securities portfolio to 5.40% from 6.09%. Interest income earned
on federal funds sold decreased by $73,000 due to a $2.8 million decrease in the
average balance and a lower yield during 2003. The lower yield on securities and
federal funds sold is primarily the result of lower market interest rates during
2003.

Interest expense is primarily generated from interest-bearing deposits, and to a
lesser degree repurchase agreements, FHLB advances and subordinated debentures.
Interest expense decreased $0.6 million during 2003 from that paid in 2002,
totaling $23.3 million in 2003 compared to $23.9 million in the previous year.
The decline in interest expense is primarily attributable to the impact of a
lower interest rate environment during 2003, which more than offset the impact
of the increase in interest-bearing liabilities during 2003. Interest-bearing
liabilities averaged $884.9 million during 2003, a level substantially higher
than the average interest-bearing liabilities of $668.0 million during 2002.
This growth resulted in increased interest expense of $6.0 million; however, a
decrease in interest expense of $6.6 million was recorded during 2003 due to
lower market interest rates on all interest-bearing liability categories except
FHLB advances and subordinated debentures. The cost of average interest-bearing
liabilities decreased from the 3.59% recorded in 2002 to 2.64% in 2003.

Growth in average certificates of deposits, totaling $133.9 million, comprised
61.7% of the increase in average interest-bearing liabilities between 2003 and
2002. Average FHLB advances increased $45.6 million, or 21.0% of the increase in
average interest-bearing liabilities. The certificate of deposit growth during
2003 equated to an increase in interest expense of $4.4 million; however, a
decrease in interest expense of $5.8 million was recorded due to the decline in
the average rate paid as higher-rate certificates of deposit matured and were
either renewed or replaced with lower-costing certificates of deposit. FHLB
advance growth during 2003 equated to an increase in interest expense of $0.9
million, with the average interest rate remaining virtually unchanged.

Growth in average savings deposits, totaling $24.1 million, equated to an
increase in interest expense of $0.5 million, while a decrease in interest
expense of $0.4 million was recorded due to the decline in the average rate paid
during 2003. Growth in average interest-bearing checking accounts and money
market accounts, totaling $7.7 million, equated to an increase in interest
expense of $0.1 million, while a decrease in interest expense of $0.2 million
was recorded due to the decline in the average rate paid during 2003. Average
short term borrowings, comprised of repurchase agreements and federal funds
purchased, increased $5.1 million during 2003, resulting in increased interest
expense of $0.1 million; however, a decrease of $0.3 million in interest expense
was recorded due to the decline in the average rate paid.

PROVISION FOR LOAN AND LEASE LOSSES
Primarily reflecting continued significant loan and lease growth, the provision
for loan and lease losses totaled $3.8 million during 2003, compared to the $3.0
million expensed during 2002. The allowance as a percentage of total loans
outstanding as of December 31, 2003 was 1.39%, compared to 1.41% at year-end
2002. Loan and lease growth during 2003 equaled $264.4 million, compared to net
loan and lease growth of $184.3 million during 2002. Net loan and lease
charge-offs during 2003 totaled $311,000, or 0.04% of average total loans and
leases. Net loan and lease charge-offs during 2002 totaled $606,000, or 0.09% of
average total loans and leases.

NONINTEREST INCOME
Noninterest income, excluding net gains on sales of securities, totaled $4.0
million in 2003, an increase of 45.2% over the $2.8 million earned in 2002.
Deposit and repurchase agreement service charges totaled $1.2 million in 2003,
an increase of $0.2 million, or 28.7%, from the amount earned in 2002. The
increase is primarily due to the growth in the number of deposit accounts,
reduction of the deposit earnings credit rate and modest increases in the
deposit fee structure. Reflecting increased volume of refinance activity
resulting from the lower interest rate environment, fees earned on referring
residential mortgage loan applicants to various third parties totaled $1.0
million in 2003, up from the $0.5 million earned in 2002. Noninterest income
related to the cash surrender value of bank owned life insurance policies
("BOLI") totaled $0.8 million in 2003, up from the $0.4 million recorded in
2002. The increase is primarily due to the additional $10.5 million BOLI
purchase in August 2002 and the impact of having a full twelve month accrual
during 2003.

In addition to providing interest income and secondary liquidity, our securities
portfolio plays an integral role in managing our net interest margin. During
2003 we consummated several bond swap transactions, resulting in a net gain on
the sales of securities of $321,000. We also consummated several bond swap
transactions during 2002, resulting in a net gain on the sales of securities of
$270,000. All of the bond swap transactions during 2003 and 2002 were
consummated in reaction to declining interest rate environments occurring at the
respective time periods of the sales, and against the backdrop of an expected
increasing interest rate environment over the next one to four years. During
2003, we sold 25 mortgage-backed securities with an aggregate par value of $15.2
million, while in 2002 we sold 18 mortgage-backed securities with an aggregate
par value of $13.5 million. Proceeds from the bond sales were reinvested into
mortgage-backed securities containing different underlying interest rate risk
characteristics than contained within the mortgage-backed securities that were
sold.

NONINTEREST EXPENSE
Noninterest expense during 2003 totaled $18.1 million, an increase of 41.4% over
the $12.8 million expensed in 2002. Of the $5.3 million growth in overhead
costs, $3.6 million (67.9%) was in salaries and benefits, and primarily reflects
the increase in full-time equivalent employees from 117 at year-end 2002 to 161
at year-end 2003, annual pay increases and an increase in the maximum dollar
amount paid in the company-wide non-lender bonus program. Occupancy, furniture
and equipment costs increased $0.6 million (31.7%) in 2003 over that expensed in
2002, primarily reflecting the opening of our Kentwood branch in December 2002,
our Knapps Corner branch and retail loan production office in Holland, Michigan
in May 2003. The remaining growth in overhead costs were generally due to
general and administrative cost increases associated with an increased asset
base.

While the dollar volume of noninterest costs has increased, the growth of net
interest income and fee income has increased by a much higher degree.
Noninterest costs during 2003 were $5.3 million higher than the level of
overhead costs expensed during 2002; however, net interest income and fee income
increased a combined $9.0 million during the same time period. Monitoring and
controlling our noninterest costs, while at the same time providing high quality
service to our customers, is one of our priorities. The efficiency ratio, a
banking industry standardized calculation that attempts to reflect the
utilization of overhead costs, reflected slight deterioration during 2003 but
remained well below banking industry averages. Computed by dividing noninterest
expenses by net interest income plus noninterest income, the efficiency ratio
was 50.7% during 2003, compared to 47.9% during 2002. The deterioration is
primarily due to the increase in staff and the opening of the three offices
noted above.

FEDERAL INCOME TAX EXPENSE
Federal income tax expense was $3.8 million in 2003, an increase of $0.6
million, or 19.5% over the $3.2 million expensed during 2002. The increase is
primarily due to the growth in our pre-federal income tax profitability, which
was only partially offset by a decline in our effective federal income tax rate
from 29.0% in 2002 to 27.4% in 2003.

RESULTS OF OPERATIONS
FOR THE YEARS ENDED DECEMBER 31, 2002 AND 2001

SUMMARY
We recorded strong earnings performance during 2002. Net income was $7.8
million, or $1.43 per basic share and $1.41 per diluted share. This earnings
performance compares very favorably to net income of $4.5 million, or $1.11 per
basic share and $1.10 per diluted share, recorded in 2001. The $3.3 million
improvement in net income represents an increase of 73.0%, while diluted
earnings per share were up 28.2%, with the difference reflecting the impact of
our common stock sales during 2001 and resulting increases in average common
shares outstanding. The earnings improvement during 2002 over that of 2001 is
primarily attributable to increased net interest income and improved operating
efficiencies resulting from asset growth, strong credit culture, controlled
overhead expenses and increased fee income.

NET INTEREST INCOME
Net interest income, the difference between revenue generated from earning
assets and the interest cost of funding those assets, is our primary source of
earnings. Interest income (adjusted for tax-exempt income) and interest expense
totaled $48.2 million and $23.9 million during 2002, respectively, providing for
net interest income of $24.3 million. This performance compares favorably to
that of 2001 when interest income and interest expense were $45.0 million and
$28.2 million, respectively, providing for net interest income of $16.8 million.
In comparing 2002 with 2001, interest income increased 7.1%, interest expense
was down 14.9% and net interest income increased 44.6%. The level of net
interest income is primarily a function of asset size, as the weighted average
interest rate received on earning assets is greater than the weighted average
interest cost of funding sources; however, factors such as types of assets and
liabilities, interest rate risk, common stock sales, liquidity, and customer
behavior also impact net interest income as well as the net interest margin. The
net interest margin improved from 2.89% in 2001 to 3.19% in 2002, an increase of
10.4%.

Interest income is primarily generated from the loan portfolio, and to a lesser
degree from securities, federal funds sold and short term investments. Interest
income increased $3.2 million during 2002 from that earned in 2001, totaling
$48.2 million in 2002 compared to $45.0 million in the previous year. The
increase is due to the growth in earning assets, which more than offset the
impact of the declining interest rate environment in 2002. Reflecting the lower
interest rates, the yield on average earning assets decreased from 7.73%
recorded in 2001 to 6.34% in 2002.

The growth in interest income is attributable to an increase in earning assets.
During 2002, earning assets averaged $761.3 million, a level substantially
higher than the average earning assets of $582.1 million during 2001. Growth in
average total loans, totaling $168.8 million, comprised 94.2% of the increase in
average earnings assets. Interest income generated from the loan portfolio
increased $3.2 million during 2002 over the level earned in 2001, comprised of
an increase of $11.8 million from the growth in the loan portfolio which was
partially offset by a decrease of $8.6 million due to the decline in the yield
earned on the loan portfolio to 6.42% from 7.95%. The decline in the loan
portfolio yield is primarily due to decreased market interest rates during 2002.

Growth in the securities portfolio also added to the increase in interest income
during 2002 over that of 2001. Average securities increased by $15.8 million in
2002, increasing from $67.7 million in 2001 to $83.4 million in 2002. The growth
equated to an increase in interest income of $1.0 million, which was partially
offset by a decrease of $0.6 million due to the decline in the yield earned on
the securities portfolio to 6.09% from 6.80%. Interest income earned on federal
funds sold decreased by $0.4 million due to a $5.4 million decrease in the
average balance and a lower yield during 2002. The lower yield on securities and
federal funds sold is the result of decreased market interest rates during 2002.

Interest expense is primarily generated from interest-bearing deposits, and to a
lesser degree repurchase agreements, subordinated debentures and Federal Home
Loan Bank advances. Interest expense decreased $4.2 million during 2002 from
that paid in 2001, totaling $23.9 million in 2002 compared to $28.2 million in
the previous year. The decline in interest expense is primarily attributable to
the impact of the declining interest rate environment during 2002, which more
than offset the impact of the increase in interest-bearing liabilities during
2002. Interest-bearing liabilities averaged $668.0 million during 2002, a level
substantially higher than the average interest-bearing liabilities of $514.7
million during 2001. This growth resulted in increased interest expense of $6.8
million; however, a decrease in interest expense of $11.0 million was recorded
during 2002 due to lower market interest rates on all interest-bearing liability
categories except trust preferred securities that have a fixed interest rate.
The cost of average interest-bearing liabilities decreased from the 5.48%
recorded in 2001 to 3.59% in 2002.

<PAGE>


Growth in average certificates of deposits, totaling $118.1 million, comprised
77.0% of the increase in average interest-bearing liabilities between 2002 and
2001. The certificate of deposit growth during 2002 equated to an increase in
interest expense of $5.7 million; however, a decrease in interest expense of
$9.3 million was recorded due to the decline in the average rate paid as
higher-rate certificates of deposit matured and were either renewed or replaced
with lower-costing certificates of deposit. Increases in repurchase agreements
and other interest-bearing deposits added to interest expense; however, the
decline in interest rates paid on these funding liabilities more than offset the
increased costs due to dollar volume growth. Average repurchase agreements grew
from $34.7 million in 2001 to $44.4 million in 2002. The growth equated to an
increase in interest expense of $0.3 million; however, a decrease of $0.6
million in interest expense was recorded due to the decline in the average rate
paid. Lower interest rates paid on interest-bearing checking accounts, savings
deposits and money market accounts reduced, in aggregate, $1.1 million in
interest expense during 2002, while the increase in dollar volume added $0.7
million in interest expense.

PROVISION FOR LOAN AND LEASE LOSSES
Primarily reflecting continued significant loan and lease growth, the provision
for loan and lease losses totaled $3.0 million during 2002, compared to the $2.4
million expensed during 2001. The allowance as a percentage of total loans
outstanding as of December 31, 2002 was 1.41%, compared to 1.45% at year-end
2001. Net loan and lease charge-offs during 2002 totaled $606,000, or 0.09% of
average total loans and leases. Net loan and lease charge-offs during 2001
totaled $178,000, or 0.04% of average total loans and leases.

NONINTEREST INCOME
Noninterest income, excluding net gains on sales of securities, totaled $2.8
million in 2002, an increase of 66.4% over the $1.7 million earned in 2001.
Deposit and repurchase agreement service charges totaled $915,000 in 2002, an
increase of $386,000, or 73.0%, from the amount earned in 2001. The increase is
primarily due to the growth in the number of deposit accounts, reduction of the
deposit earnings credit rate and modest increases in the deposit fee structure.
Reflecting increased volume of refinance activity resulting from the decreased
interest rate environment, fees earned on referring residential mortgage loan
applicants to various third parties totaled $534,000 in 2002, up from the
$401,000 earned in 2001. Usage fees on credit and debit cards totaled $262,000
in 2002, up from the $166,000 earned in 2001. Letter of credit commitment fees
totaled $307,000 during 2002, down from the $379,000 earned in 2001.

Noninterest income related to cash surrender value of BOLI totaled $409,000 in
2002, up from the $99,000 recorded in 2001. The increase is primarily due to the
additional $10.5 million BOLI purchase in August 2002 and the impact of having a
full twelve month accrual of the $3.9 million in BOLI that were purchased at
various time intervals during mid-2001. The BOLI policies represent a
combination of whole life and term insurance. The purchase made in 2002 was done
primarily to mitigate the impact of the rapidly increasing cost of employee
medical and long term disability insurance policies resulting from increased
premiums charged by our insurance carriers and the hiring of additional staff,
while the 2001 purchases were done primarily to mitigate the interest cost of
and provide a funding mechanism for our bank's non-qualified deferred
compensation program. Our bank is the sole beneficiary of the term life
insurance policies that are part of the BOLI purchased in 2002, while any
payments made under the term life insurance portion of the BOLI purchased in
2001 may be shared between our bank and the officers' named beneficiaries. As
part of the BOLI purchase in August 2002, our insurance company received a
one-time insurance commission finders fee of $108,000.

In addition to providing interest income and secondary liquidity, our securities
portfolio plays an integral role in managing our net interest margin. During
2002 we consummated two bond swap transactions, resulting in a net gain on the
sales of securities of $270,000. We also consummated two bond swap transactions
during 2001, resulting in a net gain on the sales of securities of $207,000. All
four bond swap transactions were consummated in reaction to the declining
interest rate environment occurring at the respective time periods of the sales,
and against the backdrop of an expected increasing interest rate environment
over the next one to four years. During 2002, we sold 18 mortgage-backed
securities with an aggregate par value of $13.5 million. Proceeds from the bond
sales were reinvested into mortgage-backed securities containing different
underlying interest rate risk characteristics than contained within the
mortgage-backed securities that were sold.

NONINTEREST EXPENSE
Noninterest expense during 2002 totaled $12.8 million, an increase of 35.2% over
the $9.5 million expensed in 2001. Of the $3.3 million growth in overhead costs,
$2.1 million (63.6%) was in salaries and benefits, and primarily reflects the
increase in full-time equivalent employees from 96 at year-end 2001 to 117 at
year-end 2002, annual pay increases and an increase in the maximum dollar amount
paid in the company-wide non-lender bonus program. Occupancy, furniture and
equipment costs increased $0.7 million (59.3%) in 2002 over that expensed in
2001, primarily reflecting the opening of our new administrative office and the
combined branch and operations center in the latter part of 2001. The remaining
growth in overhead costs were generally due to general and administrative cost
increases associated with an increased asset base.

While the dollar volume of noninterest costs have increased, the growth of net
interest income and fee income have increased by a much higher degree.
Noninterest costs during 2002 were $3.3 million higher than the level of
overhead costs expensed during 2001; however, net interest income and fee income
increased a combined $8.4 million during the same time period. Monitoring and
controlling our noninterest costs, while at the same time providing high quality
service to our customers, is one of our priorities. The efficiency ratio, a
banking industry standardized calculation that attempts to reflect the
utilization of overhead costs, continued to show improvement during 2002.
Computed by dividing noninterest expenses by net interest income plus
noninterest income, the efficiency ratio was 47.9% during 2002. This level
compares favorably to the efficiency ratio of 51.7% recorded during 2001, and
reflects the improved efficiencies resulting from increased net interest income
and fee income, and controlled overhead costs.

FEDERAL INCOME TAX EXPENSE
Federal income tax expense was $3.2 million in 2002, an increase of $1.2
million, or 59.1% over the $2.0 million expensed during 2001. The increase is
primarily due to the growth in our pre-federal income tax profitability, which
was only partially offset by a decline in our effective federal income tax rate
from 30.7% in 2001 to 29.0% in 2002.

CAPITAL RESOURCES

Shareholders' equity is a noninterest-bearing source of funds that provides
support for our asset growth. Shareholders' equity was $130.2 million and $79.8
million at December 31, 2003 and 2002, respectively. The $50.4 million increase
during 2003 is primarily attributable to the sale of common stock and net income
from operations. In October we completed the sale of 1,374,606 shares of common
stock through a public offering, raising $42.8 million net of issuance costs.
Net income from operations totaled $10.0 million during 2003. Negatively
impacting shareholders' equity during 2003 was the payment of cash dividends,
which totaled $1.8 million. Shareholders' equity was also negatively impacted by
a $0.8 million mark-to-market adjustment for available for sale securities as
defined in SFAS No. 115, resulting primarily from the changing interest rate
environment during 2003.

We and our bank are subject to regulatory capital requirements administered by
the State of Michigan and federal banking agencies. Failure to meet the various
capital requirements can initiate regulatory action that could have a direct
material effect on the financial statements. Our and our bank's capital ratios
as of December 31, 2003 and 2002 are disclosed under Note 17 on pages F-44 and
F-45 of the Notes to Consolidated Financial Statements.

Our ability to pay cash and stock dividends is subject to limitations under
various laws and regulations and to prudent and sound banking practices. On
January 6, 2003, we declared a 5% common stock dividend, payable on February 3,
2003 to record holders as of January 17, 2003. This represented the third
straight year we had declared and paid a 5% stock dividend. Also, during 2003 we
declared and paid a $0.08 per common share cash dividend in each calendar
quarter, totaling $1.8 million. On January 6, 2004, we declared a $0.09 per
common share cash dividend that will be paid on March 10, 2004 to shareholders
of record on February 10, 2004.

LIQUIDITY

Liquidity is measured by our ability to raise funds through deposits, borrowed
funds, capital or cash flow from the repayment of loans and investment
securities. These funds are used to meet deposit withdrawals, maintain reserve
requirements, fund loans and operate our company. Liquidity is primarily
achieved through the growth of deposits (both local and out-of-area) and liquid
assets such as securities available for sale, matured securities, and federal
funds sold. Asset and liability management is the process of managing the
balance sheet to achieve a mix of earning assets and liabilities that maximizes
profitability, while providing adequate liquidity.

Our liquidity strategy is to fund loan growth with deposits, repurchase
agreements and other borrowed funds and to maintain an adequate level of short-
and medium-term investments to meet typical daily loan and deposit activity.
Although net deposit and repurchase agreement growth from depositors located in
the market area increased by $68.9 million, or 19.1%, during 2003, the growth
was not sufficient to meet the substantial loan growth of $264.4 million and
provide monies for additional investing activities. To assist in providing the
additional needed funds we regularly obtained certificates of deposit from
customers outside of the market area. As of December 31, 2003, out-of-area
deposits totaled $591.6 million, or 62.1% of combined deposits and repurchase
agreements, an increase in dollar volume from the $512.5 million outstanding,
but a decline from the 63.7% level of combined deposits and repurchase
agreements, as of December 31, 2002.

As a member of the Federal Home Loan Bank of Indianapolis, our bank has access
to the FHLB advance borrowing programs. As of December 31, 2003, advances
totaled $90.0 million, compared to $15.0 million outstanding as of December 31,
2002. Based on available collateral at December 31, 2003, our bank could borrow
up to $156.8 million.

We have the ability to borrow money on a daily basis through correspondent banks
using established federal funds purchased lines. During 2003, our federal funds
purchased position averaged $3.6 million, compared to an average federal funds
sold position of $5.1 million. At December 31, 2003, our established unsecured
federal funds purchased lines totaled $35.0 million.

In addition to normal loan funding and deposit flow, we also need to maintain
liquidity to meet the demands of certain unfunded loan commitments and standby
letters of credit. At December 31, 2003, we had a total of $284.1 million in
unfunded loan commitments and $57.9 million in unfunded standby letters of
credit. Of the total unfunded loan commitments, $210.5 million were commitments
available as lines of credit to be drawn at any time as customers' cash needs
vary, and $73.6 million were for loan commitments scheduled to close and become
funded within the next three months. We monitor fluctuations in loan balances
and commitment levels, and include such data in our overall liquidity
management.

MARKET RISK ANALYSIS

Our primary market risk exposure is interest rate risk and, to a lesser extent,
liquidity risk. All of our transactions are denominated in U.S. dollars with no
specific foreign exchange exposure. We have only limited agricultural-related
loan assets and therefore have no significant exposure to changes in commodity
prices. Any impact that changes in foreign exchange rates and commodity prices
would have on interest rates are assumed to be insignificant. Interest rate risk
is the exposure of our financial condition to adverse movements in interest
rates. We derive our income primarily from the excess of interest collected on
interest-earning assets over the interest paid on interest-bearing liabilities.
The rates of interest we earn on our assets and owe on our liabilities generally
are established contractually for a period of time. Since market interest rates
change over time, we are exposed to lower profitability if we cannot adapt to
interest rate changes. Accepting interest rate risk can be an important source
of profitability and shareholder value; however, excessive levels of interest
rate risk could pose a significant threat to our earnings and capital base.
Accordingly, effective risk management that maintains interest rate risk at
prudent levels is essential to our safety and soundness.



                                      F-19
<PAGE>
Evaluating the exposure to changes in interest rates includes assessing both the
adequacy of the process used to control interest rate risk and the quantitative
level of exposure. Our interest rate risk management process seeks to ensure
that appropriate policies, procedures, management information systems and
internal controls are in place to maintain interest rate risk at prudent levels
with consistency and continuity. In evaluating the quantitative level of
interest rate risk we assess the existing and potential future effects of
changes in interest rates on our financial condition, including capital
adequacy, earnings, liquidity and asset quality.

We use two interest rate risk measurement techniques. The first, which is
commonly referred to as GAP analysis, measures the difference between the dollar
amounts of interest-sensitive assets and liabilities that will be refinanced or
repriced during a given time period. A significant repricing gap could result in
a negative impact to the net interest margin during periods of changing market
interest rates.

The following table depicts our GAP position as of December 31, 2003 (dollars in
thousands).

The second interest rate risk measurement used is commonly referred to as net
interest income simulation analysis. We believe that this methodology provides a
more accurate measurement of interest rate risk than the GAP analysis, and
therefore, serves as our primary interest rate risk measurement technique. The
simulation model assesses the direction and magnitude of variations in net
interest income resulting from potential changes in market interest rates. Key
assumptions in the model include prepayment speeds on various loan and
investment assets; cash flows and maturities of interest-sensitive assets and
liabilities; and changes in market conditions impacting loan and deposit volume
and pricing. These assumptions are inherently uncertain, subject to fluctuation
and revision in a dynamic environment; therefore, the model cannot precisely
estimate net interest income or exactly predict the impact of higher or lower
interest rates on net interest income. Actual results will differ from simulated
results due to timing, magnitude, and frequency of interest rate changes and
changes in market conditions and our strategies, among other factors.

We conducted multiple simulations as of December 31, 2003, whereby it was
assumed that a simultaneous, instant and sustained change in market interest
rates occurred. The following table reflects the suggested impact on net
interest income over the next twelve months, which is well within our policy
parameters established to manage and monitor interest rate risk.

In addition to changes in interest rates, the level of future net interest
income is also dependent on a number of other variables, including: the growth,
composition and absolute levels of loans, deposits, and other earning assets and
interest-bearing liabilities; economic and competitive conditions; potential
changes in lending, investing, and deposit gathering strategies; client
preferences; and other factors.

Board of Directors and Shareholders
Mercantile Bank Corporation
Wyoming, Michigan


We have audited the accompanying consolidated balance sheets of Mercantile Bank
Corporation as of December 31, 2003 and 2002 and the related consolidated
statements of income, changes in shareholders' equity and cash flows for each of
the three years in the period ended December 31, 2003. These financial
statements are the responsibility of Mercantile's management. Our responsibility
is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Mercantile Bank
Corporation as of December 31, 2003 and 2002, and the results of its operations
and its cash flows for each of the three years in the period ended December 31,

                          MERCANTILE BANK CORPORATION
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                           December 31, 2003 and 2002
--------------------------------------------------------------------------------

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation: The consolidated financial statements include the
accounts of Mercantile Bank Corporation ("Mercantile") and its subsidiaries,
Mercantile Bank of West Michigan ("Bank") and MBWM Capital Trust I ("Capital
Trust"), and of Mercantile Bank Mortgage Company, LLC ("Mortgage Company"),
Mercantile BIDCO, Inc. ("Mercantile BIDCO"), Mercantile Bank Real Estate Co.,
LLC ("Mercantile Real Estate") and Mercantile Insurance Center, Inc.
("Mercantile Insurance"), subsidiaries of our bank, after elimination of
significant intercompany transactions and accounts.

Nature of Operations: Mercantile was incorporated on July 15, 1997 to establish
and own the Bank based in Grand Rapids, Michigan. The Bank is a community-based
financial institution. The Bank began operations on December 15, 1997, after
several months of work by incorporators and employees in preparing applications
with the various regulatory agencies and obtaining insurance and building space.
The Bank's primary deposit products are checking, savings, and term certificate
accounts, and its primary lending products are commercial loans, commercial
leases, residential mortgage loans, and installment loans. Substantially all
loans and leases are secured by specific items of collateral including business
assets, real estate and consumer assets. Commercial loans and leases are
expected to be repaid from cash flow from operations of businesses. Real estate
loans are secured by both commercial and residential real estate. The Bank's
loan accounts are primarily with customers located in western Michigan, within
Kent County and Ottawa County. The Bank's retail deposits are also from
customers located in western Michigan. As an alternative source of funds, the
Bank has also issued certificates to depositors outside of the Bank's primary
market area. Substantially all revenues are derived from banking products and
services.

Capital Trust was formed in September 1999. All of the common securities of this
special purpose trust are owned by Mercantile. Capital Trust exists solely to
issue capital securities.

Mercantile Bank Mortgage Company was formed during 2000. A subsidiary of the
Bank, Mercantile Bank Mortgage Company had been established to increase the
profitability and efficiency of the mortgage loan operations. Mercantile Bank
Mortgage Company initiated business on October 24, 2000 via the Bank's
contribution of most of its residential mortgage loan portfolio and
participation interests in certain commercial mortgage loans. On the same date
the Bank also transferred its residential mortgage origination function
Mercantile Bank Mortgage Company. On January 1, 2004, Mercantile Bank Mortgage
Company was reorganized as Mercantile Bank Mortgage Company, LLC, a newly
established limited liability company, which is 99% owned by the Bank and 1%
owned by Mercantile BIDCO. Mortgage loans originated and held by the Mercantile
Bank Mortgage Company are serviced by the Bank pursuant to a servicing
agreement.

On February 7, 2002, Mercantile BIDCO, a wholly-owned subsidiary of the Bank,
was granted a license by the Michigan Office of Financial and Insurance Services
to operate as a Michigan Business and Industrial Development Company, a
non-depository Michigan financial institution. Mercantile BIDCO offers equipment
lease financing, asset based loans, junior debt facilities and other financing
where equity features may be part of the facility pricing.

Mercantile Insurance was formed during 2002 through the acquisition of an
existing shelf insurance agency. Insurance products are offered through an
Agency and Institutions Agreement among Mercantile Insurance, the Bank and
Burnham Insurance Group. The insurance products are marketed through a central
facility operated by the Michigan Bankers Insurance Association, members of
which include the insurance subsidiaries of various Michigan-based financial
institutions and Burnham Insurance Group. Mercantile Insurance receives
commissions based upon written premiums produced under the Agency and
Institutions Agreement.

Mercantile Real Estate was organized on July 21, 2003, principally to develop,
construct, and own a new facility to be constructed in downtown Grand Rapids
which will serve as our bank's new main office and Mercantile Bank Corporation's
new headquarters.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                           December 31, 2003 and 2002
--------------------------------------------------------------------------------


NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Mercantile filed an election to become a financial holding company pursuant to
Title I of the Gramm-Leach-Bliley Act and implementing Federal Reserve Board
regulations effective March 23, 2000.

Use of Estimates: To prepare financial statements in conformity with accounting
principles generally accepted in the United States of America, management makes
estimates and assumptions based on available information. These estimates and
assumptions affect the amounts reported in the financial statements and the
disclosures provided, and future results could differ. The allowance for loan
and lease losses and the fair values of financial instruments are particularly
subject to change.

Cash Flow Reporting: Cash and cash equivalents include cash on hand, demand
deposits with other financial institutions, short-term investments (securities
with daily put provisions) and federal funds sold. Cash flows are reported net
for customer loan and deposit transactions, interest-bearing time deposits with
other financial institutions and short-term borrowings with maturities of 90
days or less.

Securities: Securities classified as held to maturity are carried at amortized
cost when management has the positive intent and ability to hold them to
maturity. Securities available for sale consist of those securities which might
be sold prior to maturity due to changes in interest rates, prepayment risks,
yield and availability of alternative investments, liquidity needs or other
factors. Securities classified as available for sale are reported at fair value
with unrealized holding gains or losses reported in other comprehensive income.
Other securities such as Federal Home Loan Bank stock are carried at cost.

Premiums and discounts on securities are recognized in interest income using the
interest method over the estimated life of the security. Gains and losses on the
sale of securities available for sale are determined based upon amortized cost
of the specific security sold. Securities are written down to fair value when a
decline in fair value is not temporary.

Loans and Leases: Loans and leases that management has the intent and ability to
hold for the foreseeable future or until maturity or payoff are reported at the
principal balance outstanding, net of deferred loan fees and costs and an
allowance for loan and lease losses. Interest income is reported on the interest
method and includes amortization of net deferred loan fees and costs over the
loan term. Interest income is not reported when full loan repayment is in doubt,
typically when the loan or lease is impaired or payments are past due over 90
days. Payments received on such loans and leases are reported as principal
reductions. In all cases, loans and leases are placed on nonaccrual or
charged-off at an earlier date if collection of principal or interest is
considered doubtful.

All interest accrued but not received for loans placed on nonaccrual is reversed
against interest income. Interest received on such loans and leases is accounted
for on the cash-basis or cost-recovery method, until qualifying for return to
accrual. Loans and leases are returned to accrual status when all the principal
and interest amounts contractually due are brought current and future payments
are reasonably assured.

Allowance for Loan and Lease Losses: The allowance for loan and lease losses is
a valuation allowance for probable incurred credit losses, increased by the
provision for loan and lease losses and recoveries, and decreased by
charge-offs. Management estimates the allowance balance required based on past
loan loss experience, the nature and volume of the portfolio, information about
specific borrower situations and estimated collateral values, and economic
conditions. Allocations of the allowance may be made for specific loans and
leases, but the entire allowance is available for any loan or lease that, in
management's judgment, should be charged-off. Loan and lease losses are charged
against the allowance when management believes the uncollectibility of a loan or
lease balance is confirmed.

--------------------------------------------------------------------------------


NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

A loan or lease is impaired when full payment under the loan or lease terms is
not expected. Impairment is evaluated in aggregate for smaller-balance loans of
similar nature such as residential mortgage, consumer and credit card loans, and
on an individual loan basis for other loans. If a loan or lease is impaired, a
portion of the allowance is allocated so that the loan or lease is reported,
net, at the present value of estimated future cash flows using the loan's or
leases' existing rate or at the fair value of collateral if repayment is
expected solely from the collateral. Loans and leases are evaluated for
impairment when payments are delayed, typically 90 days or more, or when the
internal grading system indicates a doubtful classification.

Premises and Equipment: Land is carried at cost. Premises and equipment are
stated at cost less accumulated depreciation. Depreciation is computed using
both straight-line and accelerated methods over the estimated useful lives of
the respective assets. Maintenance, repairs and minor alterations are charged to
current operations as expenditures occur and major improvements are capitalized.

Long-term Assets: Premises and equipment and other long-term assets are reviewed
for impairment when events indicate their carrying amount may not be recoverable
from future undiscounted cash flows. If impaired, the assets are recorded at
discounted amounts. Issuance costs of subordinated debentures are amortized over
the term of the debentures.

Foreclosed Assets: Assets acquired through or instead of foreclosure are
initially recorded at fair value when acquired, establishing a new cost basis.
If fair value declines, a valuation allowance is recorded through expense. Costs
after acquisition are expensed.

Bank Owned Life Insurance: The Bank has purchased life insurance policies on
certain key officers. Bank owned life insurance is recorded at its cash
surrender value, or the amount that can be realized.

Repurchase Agreements: Substantially all repurchase agreement liabilities
represent amounts advanced by various customers. Securities are pledged to cover
these liabilities, which are not covered by federal deposit insurance.

Stock Compensation: Employee compensation expense under stock option plans is
reported using the intrinsic value method. No stock-based compensation cost is
reflected in net income, as all options granted had an exercise price equal to
or greater than the market price of the underlying common stock at date of
grant. The following table illustrates the effect on net income and earnings per
share if expense was measured using the fair value recognition provisions of
FASB Statement 123, Accounting for Stock-Based Compensation.

Income Taxes: Income tax expense is the total of the current year income tax due
or refundable and the change in deferred tax assets and liabilities. Deferred
tax assets and liabilities are the expected future tax amounts for the temporary
differences between the carrying amounts and tax bases of assets and
liabilities, computed using enacted tax rates. A valuation allowance, if needed,
reduces deferred tax assets to the amount expected to be realized.

Financial Instruments: Financial instruments include off-balance-sheet credit
instruments, such as commitments to make loans and standby letters of credit,
issued to meet customer financing needs. The face amount for these items
represents the exposure to loss, before considering customer collateral or
ability to repay. Such financials instruments are recorded when they are funded.

Fair Values of Financial Instruments: Fair values of financial instruments are
estimated using relevant market information and other assumptions, as more fully
disclosed separately. Fair value estimates involve uncertainties and matters of
significant judgment regarding interest rates, credit risk, prepayments and
other factors, especially in the absence of broad markets for particular items.
Changes in assumptions or in market conditions could significantly affect the
estimates. The fair value estimates of existing on- and off-balance sheet
financial instruments does not include the value of anticipated future business
or the values of assets and liabilities not considered financial instruments.

Earnings Per Share: Basic earnings per share is based on weighted average common
shares outstanding during the period. Diluted earnings per share include the
dilutive effect of additional potential common shares issuable under stock
options. Earnings per share are restated for all stock dividends, including the
5% stock dividend paid on February 3, 2003, February 1, 2002 and February 1,
2001. The fair value of shares issued in stock dividends is transferred from
retained earnings to common stock.

Comprehensive Income: Comprehensive income consists of net income and other
comprehensive income. Other comprehensive income includes unrealized gains and
losses on securities available for sale which are also recognized as separate
components of equity.

New Accounting Pronouncements: During 2003, the Company adopted FASB Statement
149, Amendment of Statement 133 on Derivative Instruments and Hedging
Activities, FASB Statement 150, Accounting for Certain Financial Instruments
with Characteristics of both Liabilities and Equities, FASB Statement 132
(revised 2003), Employers' Disclosures about Pensions and Other Postretirement
Benefits, FASB Interpretation 45, Guarantor's Accounting and Disclosure
Requirements for Guarantees, and FASB Interpretation 46, Consolidation of
Variable Interest Entities. Adoption of the new standards did not materially
affect the Company's operating results or financial condition.

Contingencies: Loss contingencies, including claims and legal actions arising in
the ordinary course of business, are recorded as liabilities when the likelihood
of loss is probable and an amount or range of loss can be reasonably estimated.
Management does not believe there now are such matters that will have a material
effect on the financial statements.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Reclassifications: Some items in the prior year financial statements were
reclassified to conform to the current presentation.

Derivatives: All derivative instruments are recorded at their fair values. If
derivative instruments are designated as hedges of fair values, both the change
in the fair value of the hedge and the hedged item are included in current
earnings. Fair value adjustments related to cash flow hedges are recorded in
other comprehensive income and reclassified to earnings when the hedged
transaction is reflected in earnings. Ineffective portions of hedges are
reflected in earnings as they occur.

Operating Segments: While management monitors the revenue streams of the various
products and services offered, the identifiable segments are not material and
operations are managed and financial performance is evaluated on a company-wide
basis. Accordingly, all of Mercantile's financial service operations are
considered by management to be aggregated in one reportable operating segment.


NOTE 2 -- SECURITIES

The fair value of available for sale securities and the related gross unrealized
gains and losses recognized in accumulated other comprehensive income (loss)

Unrealized losses on securities have not been recognized into income because the
issuers' bonds are of high credit quality, we have the intent and ability to
hold for the foreseeable future and the decline in fair value is primarily due
to increased market interest rates. The fair value is expected to recover as the
bonds approach the maturity date.

The amortized cost and fair values of debt securities at year-end 2003, by
contractual maturity, are shown below. The contractual maturity is utilized
below for U.S. Government agency debt obligations and municipal bonds. Expected
maturities may differ from contractual maturities because borrowers may have the
right to call or prepay obligations with or without call or prepayment
penalties. Securities not due at a single maturity date, primarily mortgage
backed securities, are shown separately.

The maturities of securities and their weighted average yields at December 31,
2003 are shown in the following table. The yields for municipal securities are
shown at their tax equivalent yield.

</TABLE>

Securities sold under agreements to repurchase (repurchase agreements) generally
have original maturities of less than one year. Repurchase agreements are
treated as financings and the obligations to repurchase securities sold are
reflected as liabilities. Securities involved with the repurchase agreements are
recorded as assets of the Bank and are primarily held in safekeeping by
correspondent banks. Repurchase agreements are offered principally to certain
large deposit customers as uninsured deposit equivalent investments. Repurchase
agreements were secured by securities with a market value of $60.4 million and
$57.2 million at year-end 2003 and 2002, respectively.

assets will not be realized. Management has determined that no valuation
allowance was required at year-end 2003 or 2002.

financial instruments include commitments to extend credit and standby letters
of credit. Loan commitments to extend credit are agreements to lend to a
customer as long as there is no violation of any condition established in the
contract. Standby letters of credit are conditional commitments issued by the
Bank to guarantee the performance of a customer to a third party. Commitments
generally have fixed expiration dates or other termination clauses and may
require payment of a fee. Since many of the commitments are expected to expire
without being drawn upon, the total commitment amounts do not necessarily
represent future cash requirements.

These instruments involve, to varying degrees, elements of credit risk in excess
of the amount recognized, if any, in the balance sheet. The Bank's maximum
exposure to loan loss in the event of nonperformance by the other party to the
financial instrument for commitments to extend credit and standby letters of
credit is represented by the contractual notional amount of those instruments.
The Bank uses the same credit policies in making commitments and conditional
obligations as it does for on-balance sheet instruments. Collateral, such as
accounts receivable, securities, inventory, property and equipment, is generally
obtained based on management's credit assessment of the borrower.

Fair value of the Bank's off-balance sheet instruments (commitments to extend
credit and standby letters of credit) is based on rates currently charged to
enter into similar agreements, taking into account the remaining terms of the
agreements and the counterparties' credit standing. At year-end 2003 and 2002,
the rates on existing off-balance sheet instruments were substantially
equivalent to current market rates, considering the underlying credit standing
of the counterparties.

NOTE 12 -- BENEFIT PLANS (Continued)

Mercantile has a deferred compensation plan in which all persons serving on the
Board of Directors may defer all or portions of annual retainer and meeting
fees, with distributions to be paid only upon termination of service as a
director. The deferred amounts are categorized on Mercantile's financial
statements as long term borrowings. Up until September 30, 2001, the deferred
balances were paid interest at a rate equal to 75% of the prime rate, adjusted
at the beginning of each calendar quarter. The deferred compensation plan was
amended, effective October 1, 2001, to increase the interest rate from 75% of
the prime rate to 100% of the prime rate. Interest expense for the plan during
2003, 2002 and 2001 was $15,000, $11,000 and $6,000, respectively.

Mercantile has a non-qualified deferred compensation program in which selected
officers may defer all or portions of salary and bonus payments. The deferred
amounts are categorized on Mercantile's financial statements as other borrowed
money. The deferred balances are paid interest at a rate equal to the prime
rate, adjusted at the beginning of each calendar quarter. Interest expense for
the plan during 2003, 2002 and 2001 was $22,000, $10,000 and $2,000,

Carrying amount is the estimated fair value for cash and cash equivalents,
Federal Home Loan Bank stock, accrued interest receivable and payable, bank
owned life insurance policies, demand deposits, securities sold under agreements
to repurchase, and variable rate loans or deposits that reprice frequently and
fully. Security fair values are based on market prices or dealer quotes, and if
no such information is available, on the rate and term of the security and
information about the issuer. For fixed rate loans or deposits and for variable
rate loans or deposits with infrequent repricing or repricing limits, fair value
is based on discounted cash flows using current market rates applied to the
estimated life and credit risk. Fair value of subordinated debentures and
Federal Home Loan Bank advances is based on current rates for similar financing.
Fair value of off balance sheet items is estimated to be nominal.

Cumulative Preferred Securities ("trust preferred securities") at $10.00 per
trust preferred security in a September 1999 offering. The proceeds from the
sale of the trust preferred securities were used by MBWM Capital Trust I to
purchase an equivalent amount of subordinated debentures from Mercantile. The
trust preferred securities carry a fixed rate of 9.60%, have a stated maturity
of 30 years, and, in effect, are guaranteed by Mercantile. The securities are
redeemable at par after 5 years. Distributions on the trust preferred securities
are payable quarterly on January 15, April 15, July 15 and October 15. The first
distribution was paid on October 15, 1999. Under certain circumstances,
distributions may be deferred for up to 20 calendar quarters. However, during
any such deferrals, interest accrues on any unpaid distributions at the rate of
9.60% per annum. The trust preferred securities are carried on Mercantile's
consolidated balance sheet as a liability, and the interest expense is recorded
on Mercantile's consolidated statement of income.

NOTE 16 -- SALE OF COMMON STOCK

During 2003, Mercantile sold in aggregate approximately 1.4 million shares of
common stock, raising $43.0 million net of issuance costs. Substantially all of
the net proceeds were contributed to the Bank as capital to provide support for
asset growth, fund investments in loans and securities and for general corporate
purposes.

During 2001, Mercantile sold in aggregate approximately 2.3 million shares of
common stock, raising $35.0 million net of issuance costs. Substantially all of
the net proceeds were contributed to the Bank as capital to provide support for
asset growth, fund investments in loans and securities and for general corporate
purposes.


NOTE 17 - REGULATORY MATTERS

Mercantile and the Bank are subject to regulatory capital requirements
administered by federal banking agencies. Capital adequacy guidelines and prompt
corrective action regulations involve quantitative measures of assets,
liabilities, and certain off-balance-sheet items calculated under regulatory
accounting practices. Capital amounts and classifications are also subject to
qualitative judgments by regulators about components, risk weightings, and other
factors, and the regulators can lower classifications in certain cases. Failure
to meet various capital requirements can initiate regulatory action that could
have a direct material effect on the financial statements.

The prompt corrective action regulations provide five classifications, including
well capitalized, adequately capitalized, undercapitalized, significantly
undercapitalized, and critically undercapitalized, although these terms are not
used to represent overall financial condition. If an institution is adequately
capitalized, regulatory approval is required to accept brokered deposits. If an
institution is undercapitalized, capital distributions are limited, as is asset
growth and expansion, and plans for capital restoration are required.

At year end, actual capital levels (in thousands) and minimum required levels
for Mercantile and the Bank were:

Federal and state banking laws and regulations place certain restrictions on the
amount of dividends the Bank can transfer to Mercantile and on the capital
levels that must be maintained. At year-end 2003, under the most restrictive of
these regulations (to remain well capitalized), the Bank could distribute
approximately $11.1 million to Mercantile as dividends without prior regulatory
approval.

The capital levels as of year-end 2003 and year-end 2002 include 1.6 million
trust preferred securities issued by Capital Trust in September 1999 subject to
certain limitations. Federal Reserve guidelines limit the amount of trust
preferred securities which can be included in Tier 1 capital of Mercantile to
25% of total Tier 1 capital. At year-end 2003 and year-end 2002, all $16.0
million of the trust preferred securities were included as Tier 1 capital of
Mercantile.
