<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">On May 24, 2018, the Boards of Directors of Mercantile Bank Corporation (&ldquo;Mercantile&rdquo;), and of Mercantile&rsquo;s wholly-owned subsidiary, Mercantile Bank of Michigan (the &ldquo;Bank&rdquo;), adopted an executive officer bonus plan for 2018 (the &ldquo;Executive Officer Plan&rdquo;).</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">&nbsp;</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">The Executive Officer Plan provides for cash bonuses for: Michael H. Price, the Chairman of the Board of Mercantile and the Chairman of the Board of the Bank (formerly, the Executive Chairman of the Board of Mercantile and the Executive Chairman of the Board of the Bank); Robert B. Kaminski, Jr., the President and Chief Executive Officer of Mercantile and the Chief Executive Officer of the Bank; Charles E. Christmas, the Executive Vice President, Chief Financial Officer, and Treasurer of Mercantile, and the Executive Vice President and Chief Financial Officer of the Bank; Raymond E. Reitsma, the President of the Bank and Senior Vice President of Mercantile; Robert T. Worthington, the Chief Operating Officer, Senior Vice President, General Counsel, and Secretary of Mercantile and the Bank; and Lonna L. Wiersma, the Senior Vice President and Human Resource Director of the Bank and Mercantile.</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">&nbsp;</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">The maximum amount that can be allocated to the bonus pool is $606,651 under the Executive Officer Plan, provided, however, that the maximum amount will be appropriately adjusted if (a) a newly hired employee becomes eligible to participate in the plan, (b) a participant&#39;s base salary is adjusted during the year, or (c) a participant becomes ineligible before December 31, 2018.</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">&nbsp;</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">Payment from the bonus pool under the plan, if any, is based on the achievement of targets under the following metrics for 2018:</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">&nbsp;</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">12.5%&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Non-performing assets</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">&nbsp;</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">The specific targets for each metric will be established by the Compensation Committee of Mercantile&#39;s Board of Directors.</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">&nbsp;</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">Each individual target must be met or exceeded in order for the percentage associated with that metric to be credited toward payment from the bonus pool under the plan. The accumulated percentage for each individual target attained will be applied to the bonus pool amount to determine the total amount of the bonus pool to be awarded (the &quot;Award Amount&quot;). For example, if the first four factors are attained and the next four factors are not attained, and if the maximum amount is allocated to the bonus pool under the Executive Officer Plan, the Award Amount would be $606,651 x 50% = $303,325.50.</p>

Any bonus awards that are earned under the plan will be paid to the executive officers on or before March 15, 2019.</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">&nbsp;</p>

<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">Payments under the plan are subject to specified conditions, qualifications, and clawback provisions.

Adoption of Bonus Plans
On May 24, 2018, the Boards of Directors of Mercantile Bank Corporation ("Mercantile"), and of Mercantile's wholly-owned subsidiary, Mercantile Bank of Michigan (the "Bank"), adopted an executive officer bonus plan for 2018 (the "Executive Officer Plan").
The Executive Officer Plan provides for cash bonuses for: Michael H. Price, the Chairman of the Board of Mercantile and the Chairman of the Board of the Bank (formerly, the Executive Chairman of the Board of Mercantile and the Executive Chairman of the Board of the Bank); Robert B. Kaminski, Jr., the President and Chief Executive Officer of Mercantile and the Chief Executive Officer of the Bank; Charles E. Christmas, the Executive Vice President, Chief Financial Officer, and Treasurer of Mercantile, and the Executive Vice President and Chief Financial Officer of the Bank; Raymond E. Reitsma, the President of the Bank and Senior Vice President of Mercantile; Robert T. Worthington, the Chief Operating Officer, Senior Vice President, General Counsel, and Secretary of Mercantile and the Bank; and Lonna L. Wiersma, the Senior Vice President and Human Resource Director of the Bank and Mercantile.
The maximum amount that can be allocated to the bonus pool is $606,651 under the Executive Officer Plan, provided, however, that the maximum amount will be appropriately adjusted if (a) a newly hired employee becomes eligible to participate in the plan, (b) a participant's base salary is adjusted during the year, or (c) a participant becomes ineligible before December 31, 2018.
Payment from the bonus pool under the plan, if any, is based on the achievement of targets under the following metrics for 2018:
12.5%     Non-performing assets
12.5%     Commercial loan portfolio composition
12.5%     Net interest margin
12.5%     Non-interest income
12.5%     Efficiency ratio
12.5%     Return on assets
12.5%     Return on equity
12.5%     Wholesale funds
The specific targets for each metric will be established by the Compensation Committee of Mercantile's Board of Directors.
Each individual target must be met or exceeded in order for the percentage associated with that metric to be credited toward payment from the bonus pool under the plan. The accumulated percentage for each individual target attained will be applied to the bonus pool amount to determine the total amount of the bonus pool to be awarded (the "Award Amount"). For example, if the first four factors are attained and the next four factors are not attained, and if the maximum amount is allocated to the bonus pool under the Executive Officer Plan, the Award Amount would be $606,651 x 50% = $303,325.50.
2
The Award Amount will be paid to each participant pro rata based on a uniform percentage of the participant's 2018 salary (not to exceed: 40% of the 2018 salary of each of the Executive Chairman and the Chief Executive Officer; 35% of the 2018 salary of each of the Chief Financial Officer and the President of the Bank; 32.5% of the 2018 salary of the Chief Operating Officer; and 27.5% of the 2018 salary of the Human Resources Director.) Any bonus awards that are earned under the plan will be paid to the executive officers on or before March 15, 2019.
Payments under the plan are subject to specified conditions, qualifications, and clawback provisions. The plan, to the extent provided for in the plan, may be amended by the Compensation Committee of Mercantile's Board of Directors.
A copy of the Executive Officer Plan is attached as Exhibit 10.1.
Changes in Officers
Michael H. Price retired from his role as Executive Chairman of Mercantile effective May 24, 2018. He will remain as a board member of Mercantile and the Bank and will serve as the non-employee Chairman of each board.
Lonna L. Wiersma, Senior Vice President and Human Resources Director for the Bank, was appointed to the positions of Senior Vice President and Human Resources Director for Mercantile.
Raymond E. Reitsma, President of the Bank, was appointed to the position of Senior Vice President of Mercantile.
