ITEM 1.01  ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

         On January 19, 2006, the Board of Directors of Mercantile Bank
Corporation ("Mercantile") adopted, subject to receiving shareholder approval,
the Stock Incentive Plan of 2006 (the "Plan"). The Plan authorizes the
Compensation Committee of the Board of Directors, or the Board of Directors, to
grant equity-based incentives to directors and employees of Mercantile and its
subsidiaries. These equity-based incentives may include stock options, stock
appreciation rights, restricted stock units, restricted stock, stock awards, and
other awards based on or related to shares of Mercantile common stock. Subject
to certain anti-dilution and other adjustments, 350,000 shares of Mercantile
common stock are available for awards under the Plan. No awards can be granted
under the Plan after January 18, 2016.

         The Plan was approved by Mercantile's shareholders at the annual
meeting of shareholders held on April 27, 2006. Accordingly, the adoption of the
Plan is no longer subject to the receipt of shareholder approval, and the Plan
is effective, as of January 19, 2006, the date on which it was adopted by
Mercantile's Board of Directors.

         The Plan is described in Mercantile's proxy statement that was filed
with the Securities and Exchange Commission for its April 27, 2006 annual
meeting. A copy of the Plan is set forth in Appendix A to that proxy statement,
and incorporated by reference as an exhibit to this report.
