&nbsp;&nbsp;&nbsp;Mercantile Bank of Michigan<BR>
&nbsp;&nbsp;&nbsp;401(k) Plan<BR>
Grand Rapids, Michigan

</DIV>
<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We have audited the accompanying statements of net assets available for benefits of Mercantile Bank
of Michigan 401(k) Plan (the Plan) as of December&nbsp;31, 2007 and 2006, and the related statement of
changes in net assets available for benefits for the year then ended. These financial statements
are the responsibility of the Plan&#146;s management. Our responsibility is to express an opinion on
these financial statements based on our audits.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We conducted our audit in accordance with the auditing standards of the Public Company Accounting
Oversight Board (United States). Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of material
misstatement. The Plan is not required to have, nor were we engaged to perform, an audit of its
internal controls over financial reporting. Our audit included consideration of internal controls
over financial reporting as a basis for designing audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Plan&#146;s
internal controls over financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and disclosures in the
financial statements, 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.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In our opinion, the financial statements referred to above present fairly, in all material
respects, the net assets available for benefits of the Plan as of December&nbsp;31, 2007 and 2006, and
the changes in net assets available for benefits for the year then ended, in conformity with
accounting principles generally accepted in the United States of America.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Our audits were performed for the purpose of forming an opinion on the financial statements taken
as a whole. The supplemental schedule of Assets (Held at End of Year) as of December&nbsp;31, 2007, is
presented for the purpose of additional analysis and is not a required part of the basic financial
statements, but is supplementary information required by the Department of Labor&#146;s Rules and
Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974.
This supplemental schedule is the responsibility of the Plan&#146;s management. The supplemental
schedule has been subjected to the auditing procedures applied in the audits of the basic financial
statements, and, in our opinion, is fairly presented in all material respects in relation to the
basic financial statements taken as a whole.

    <TD>The Plan&#146;s investments in mutual funds and Mercantile Bank Corporation common stock are
stated at fair value based on quoted market prices of shares held by the Plan. The
investment in the common/collective trust (Gartmore Stable Value Fund) is stated according
to the Financial Accounting Standards Board Staff Position, FSP AAG INV-1 and SOP 94-4-1,
<I>Reporting of Fully Benefit-Responsive Investment Contracts Held by Certain Investment
Companies Subject to the AICPA Investment Company Guide and Defined-Contribution Health and
Welfare and Pension Plans </I>(FSP). The FSP states that contract value is the relevant
measurement attribute for that portion of the net assets available for benefits of a
defined-contribution plan attributable to fully benefit-responsive investment contracts
because contract value is the amount participants would receive if they were to initiate
permitted transactions under the terms of the plan. As required by the FSP, the Statement
of Net Assets Available for Benefits presents the fair value of the investment contracts as
well as the adjustment of the fully benefit-responsive investment contracts from fair value
to contract value. The fair value of the CCT is based on the contract value on the last
business day of the plan year. Contract value approximates fair value. The Statement of
Changes in Net Assets Available for Benefits is prepared on a contract value basis.
Participant loans are stated at cost, which approximates fair value. Purchases and sales of
investments are recorded on a trade-date basis. Interest income is recorded on the accrual
basis. Dividends are recorded on the ex-dividend date.</TD>
