powers to indemnify any person in connection with legal proceedings brought against that person by
reason of their present or past status as an officer or director of Mercantile, provided that the
person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to
Mercantile&#146;s best interests, and with respect to any criminal action or proceeding, had no
reasonable cause to believe his or her conduct was unlawful. The Michigan Business Corporation Act
also gives Mercantile broad powers to indemnify defined persons against expenses and reasonable
settlement payments in connection with any action by or in the right of Mercantile, provided the
person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to
Mercantile&#146;s best interests, except that no indemnification may be made if that person is adjudged
to be liable to Mercantile unless and only to the extent the court in which that action was brought
determines upon application that, despite the adjudication, but in view of all the circumstances of
the case, the person is fairly and reasonably entitled to indemnity for reasonable expenses as the
court deems proper. In addition, to the

Mercantile is required by the Michigan Business Corporation Act to indemnify him or her against

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Mercantile&#146;s Articles of Incorporation provide that it shall indemnify its present and past

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Mercantile&#146;s Bylaws contain indemnification provisions concerning third party actions as well
as actions in the right of Mercantile. The Bylaws provide that Mercantile shall indemnify any
person who was or is a party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or investigative
(other than an action by or in the right of Mercantile) by reason of the fact that he or she is or

another foreign or domestic corporation, partnership, joint venture, trust or other enterprise,

the Michigan Business Corporation Act or the Michigan Banking Code.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;With respect to derivative actions, the Bylaws provide that Mercantile shall indemnify any
person who was or is a party to or is threatened to be made a party to any threatened, pending or
completed action or suit by or in the right of Mercantile to procure a judgment in its favor by
reason of the fact that he or she is or was a director or officer of Mercantile, or while serving

matter in which such person has been found liable to Mercantile except to the extent that a court
of competent jurisdiction determines upon application that, despite the adjudication of liability
but in view of all circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such expenses which such court shall deem proper.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be
permitted to directors, officers and controlling persons of Mercantile pursuant to the provisions
discussed above or otherwise, Mercantile has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed in the Securities
Act of 1933 and is, therefore, unenforceable.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Michigan Business Corporation Act permits Mercantile to purchase insurance on behalf of
its directors and officers against liability arising out of their positions with Mercantile (or
positions held with another entity at the request of Mercantile), whether or not the liabilities
would be within the indemnification provisions described above. Under an insurance policy
maintained by Mercantile, its directors and officers are insured within the limits and subject to
the limitations of the policy, against specified expenses in connection with the defense of
specified claims, actions, suits or proceedings, and specified liabilities which might be imposed
as a result of claims, actions, suits or proceedings, which may be brought against them by reason
of being or having been directors and officers of Mercantile.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><I>Limitation of Director Liability</I>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;209(1)(c) of the Michigan Business Corporation Act permits corporations to limit the
personal liability of their directors in certain circumstances. However, under the Michigan
Business Corporation Act, a corporation may not eliminate or limit a director&#146;s liability to the
corporation or its shareholders for money damages for any action taken or any failure to take any
action as a director for any of the following: (1)&nbsp;the amount of a financial benefit received by a
director to which he or she is not entitled; (2)&nbsp;intentional infliction of harm on the corporation
or its shareholders; (3)&nbsp;a violation of Section&nbsp;551 of the Michigan Business Corporation Act; and
(4)&nbsp;an intentional criminal act.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Mercantile&#146;s Articles of Incorporation provide that its directors shall not be personally
liable to it or its shareholders for monetary damages for breach of fiduciary duty, except for
liability (1)&nbsp;for any breach of the director&#146;s duty of loyalty to Mercantile or its shareholders;
(2)&nbsp;for acts or omissions not in good faith or that involve intentional misconduct or a knowing
violation of law; (3)&nbsp;for a violation of Section&nbsp;551(1) of the Michigan Business Corporation Act;
or (4)&nbsp;for any transaction from which the director derived any improper personal benefit. Under
the Michigan Business Corporation Act, if prior to October&nbsp;24, 1997 the articles of incorporation
of a corporation contained a provision which, subject to exceptions, eliminated liability of a
director as Mercantile&#146;s does, that provision is considered to eliminate liability of a director to
the extent permitted in Section&nbsp;209(1)(c) of the Michigan Business Corporation Act.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Pursuant to Mercantile&#146;s Articles of Incorporation, if the Michigan Business Corporation Act
is amended after the date of the Articles of Incorporation to authorize corporate action
eliminating or limiting the personal liability of directors, then the liability of a director of
Mercantile shall be eliminated or limited to the fullest extent permitted by the Michigan Business
Corporation Act, as so amended.

price of the Common Stock reported on The Nasdaq Stock Market (or other stock exchange or quotation

&#147;Registration Statement&#148;) of 30,000 shares of its common stock (the &#147;Plan Shares&#148;) that may be
issued under the Mercantile Bank Corporation Employee Stock Purchase Plan of 2002, as amended by
the First Amendment to the Mercantile Bank Corporation Employee Stock Purchase Plan of 2002 and
the Second Amendment to the Mercantile Bank Corporation Employee Stock Purchase Plan of 2002 (as so
amended, the &#147;Plan&#148;). This opinion is being delivered pursuant to the requirements of Item
601(b)(5) of Regulation&nbsp;S-K under the Securities Act of 1933 (the &#147;Act&#148;).

Board of Directors of Mercantile, (iv)&nbsp;resolutions of the Board of Directors of Mercantile relating

all natural persons signing or delivering an instrument, the authenticity of all documents
submitted to us as originals, the conformity to original documents of all documents submitted to us
as certified, telecopied, facsimile, conformed or photostatic copies, and the absence of any
understandings, waivers, or amendments which would vary the terms of any document which we have
reviewed. As to various questions of fact material to this opinion, we have relied upon oral or
written statements and representations of officers or other representatives of Mercantile and
upon certificates or other documents of public officials. We have further assumed that this
opinion will be used only in connection with the offer and sale of Plan Shares while the
Registration Statement remains in effect under the Act.
