forth (1) the specific reasons for such denial, (2) a specific reference to the
provisions of the Agreement on which the denial is based, (3) a description of
any additional information or material necessary for the Claimant to perfect his
or her claim, and a description of why it is needed, (4) an explanation of the
Agreement's claims review procedure and other appropriate information as to the
steps to be taken if the Claimant wishes to have the claim reviewed; and (5) a

to
                                     Page 6
<PAGE>

greater or different benefits, the Claimant shall have the opportunity to have
such claim reviewed by the Bank by filing a petition for review with the Bank
within 60 days after receipt of the notice issued by the Bank. Said petition
shall state the specific reasons which the Claimant believes entitle him or her
to benefits or to greater or different benefits. Within 60 days after receipt by

the Claimant (or counsel) shall have the right to review the pertinent
documents. The Bank shall notify the Claimant of its decision in writing within
the 60-day period, stating specifically the basis of its decision, written in a
manner to be understood by the Claimant and the specific provisions of the

the 60-day period is not sufficient, the decision may be deferred for up to
another 60 days at the election of the Bank, but notice of this deferral shall
be given to the Claimant.

SECTION 8 - Beneficiaries

         8.1 Beneficiary Designations. The Executive shall designate a
beneficiary by filing a written designation with the Bank. The Executive may

beneficiary designation, all payments shall be made to the Executive's estate.

         8.2 Facility of Payment. If a benefit is payable to a minor, to a
person declared incompetent, or to a person incapable of handling the
disposition of his or her property, the Bank may pay such benefit to the
guardian, legal representative or person having the care or custody of such
minor, incompetent person or incapable person. The Bank may require proof of
incompetence, minority or guardianship as it may deem appropriate prior to
distribution of the benefit. Such distribution shall completely discharge the
Bank from all liability with respect to such benefit.

SECTION 9 - Amendments and Termination

         9.1 This Agreement may be amended or terminated only by a written
agreement signed by the Bank and the Executive.

         9.2 Notwithstanding Section 9.1, the Bank may amend or terminate this
Agreement at any time if, pursuant to legislative, judicial or regulatory
action,

                                     Page 7
<PAGE>

continuation of the Agreement would (i) cause benefits to be taxable to the
Executive prior to actual receipt, or (ii) result in significant financial
penalties or other significantly detrimental ramifications to the Bank or the
Holding Company, other than the financial impact of paying the benefits. In no
event shall this Agreement be terminated under this section without payment to
the Executive of the Deferral Account balance attributable to the Executive's
Deferrals and interest credited on such amounts.

SECTION 10 - Status as an Unsecured General Creditor.

         10.1 Notwithstanding anything contained herein to the contrary: (i) the
Executive shall have no legal or equitable rights, interests or claims in or to
any specific property or assets of the Bank as a result of this Agreement; (ii)
none of the Bank's assets shall be held in or under any trust for the benefit of
the Executive or held in any way as security for the fulfillment of the
obligations of the Bank under this Agreement; (iii) all of the Bank's assets
shall be and remain the general unpledged and unrestricted assets of the Bank;

through (v) above, the Bank and the Executive acknowledge and agree that, in the
event of a Change in Control, upon request of the Executive, or in the Bank's
discretion if the Executive does not so request and the Bank nonetheless deems
it appropriate, the Bank shall establish, concurrent with this agreement, a
Rabbi Trust or multiple Rabbi Trusts (the "Trust" or "Trusts") upon such terms
and conditions as the Bank, in its sole discretion, deems appropriate and in
compliance with applicable provisions of the Code, in order to permit the Bank
to make contributions and/or transfer assets to the Trust or Trusts to discharge
its obligations pursuant to this Agreement. The principal of the Trust or Trusts
and any earnings thereon shall be held separate and apart from other funds of
the Bank to be used exclusively for discharge of the Bank's obligations pursuant
to this Agreement and shall continue to be subject to the claims of the Bank's
general creditors until paid to the Executive in such manner and at such times
as specified in this Agreement.

         10.2 Bank reserves the right to determine, in its sole and absolute
discretion, whether, to what extent and by what method, if any, to provide for
the payment of the amounts which may be payable to the Executive, under the
terms of this Agreement. In the event that the Bank elects to fund this
Agreement, in whole or in part, through the use

                                     Page 8
<PAGE>

of life insurance or annuities, or both, the Bank shall determine the ownership
and beneficial interests of any such policy of life insurance or annuity. The
Bank further reserves the right, in its sole and absolute discretion, to
terminate any such policy, and any other devise used to fund its obligations
under this Agreement, at any time, in whole or in part. Consistent with Section
10.1 above, the Executive shall have no right, title or interest in or to any
funding source or amount utilized by the Bank pursuant to this Agreement, and
any such funding source or amount shall not constitute security for the
performance of the Bank's obligations pursuant to this Agreement. In connection
with the foregoing, the Executive agrees to execute such documents and undergo
such medical examinations or tests which the Bank may request and which may be
reasonably necessary to facilitate any funding for this Agreement including,
without limitation, the Bank's acquisition of any policy of insurance or
annuity.

         10.3 Notwithstanding any other provision of the Agreement, the Board of
Directors of the Bank or the Holding Company may, its sole and absolute
discretion: (i) accelerate the payment of the amounts due under the terms of
this Agreement, provided that the Executive consents to the revised payout terms
determined appropriate by the Board of Directors; (ii) modify other terms or
conditions of the Agreement, as the Board of Directors deems necessary or
appropriate, in response to changes in legislation, to rules, regulations or
rulings issued under the Internal Revenue Code, or to other similar events
having a substantial impact on the costs and benefits to the Bank of its
obligations under the Agreement, provided that the Executive shall receive a
substantially equivalent benefit in the event that a benefit existing under the
Agreement is canceled as a result of such modification.

and transferees.

         11.2 No Guarantee of Employment. This Agreement is not an employment

asset of the Bank to which the Executive and beneficiary have no preferred or
secured claim.

procedure used or established by JAMS, or if there are none, the rules of
procedure used or established by AAA. Any award rendered by JAMS or AAA shall be
final and binding upon the parties, and as applicable, their respective heirs,
beneficiaries, legal representatives, agents, successors and assigns, and may be
entered in any court having jurisdiction thereof. Any arbitration hereunder
shall be conducted in The Dalles, Oregon, unless otherwise agreed to by the
parties.

         11.15 Attorneys' Fees. In the event of any arbitration or litigation
concerning any controversy, claim or dispute between the parties hereto, arising
out of or relating to this Agreement or the breach hereof, or the interpretation
hereof, the prevailing party shall be entitled to recover from the losing party
reasonable expenses, attorneys' fees and costs incurred in connection therewith
or in the enforcement or collection of any judgment or award rendered therein.
The "prevailing party" means the party determined by the arbitrator(s) or court,
as the case may be, to have most nearly prevailed, even if such party did not
prevail in all matters, not necessarily the one in whose favor a judgment is
rendered.

         11.16 Notice. Any notice required or permitted of either the Executive

         11.17. Nonwaiver. The failure of either party to enforce at any time or
for any period of time any one or more of the terms or conditions of this

                    SECOND AMENDMENT TO EMPLOYMENT AGREEMENT

     THIS AMENDMENT ("Amendment") is made as of the 17th day of November, 2005
by and among Mercantile Bank Corporation, a Michigan corporation (the
"Company"), Mercantile Bank of Michigan, a Michigan banking corporation (the
"Bank", and collectively with the Company, the "Employers", and each an
"Employer"), and Gerald R. Johnson, Jr. (the "Employee").

                                    RECITALS

     A. The Company, the Bank and the Employee have previously entered into an
Employment Agreement dated as of October 18, 2001, as amended by a letter
amendment dated October 17, 2002 (the "Employment Agreement").

     B. The Company, the Bank and the Employee wish to amend the Employment
Agreement to make changes to cause payments under the Employment Agreement to be
in compliance with Section 409A of the Internal Revenue Code of 1986, as amended
(the "Code").

                               TERMS OF AGREEMENT

     In consideration of the mutual covenants and obligations set forth herein,
the Employers and the Employee amend the Employment Agreement as follows:

     1.   Section 4 is amended and restated in its entirety as follows:

          4. Participation in Employee Benefit Plans. In addition to the cash
     compensation payable to the Employee under this Agreement, the Employee
     shall be entitled to participate in such employee benefit plans, whether
     contributory or non-contributory, such as group life and disability
     insurance plans, hospital, surgical, vision and dental benefit plans or
     other bonus incentive, profit sharing, stock option, retirement or other
     employee benefit plans of the Employers as may now or hereafter exist to
     the extent that the Employee meets the eligibility requirements of any such
     plans. All such group life and disability insurance plans, and hospital,
     surgical, vision and dental benefit plans are hereafter referred to as
     "Life, Disability and Medical Plans". If any bonus or incentive
     compensation plan payments constitute "deferred compensation" within the
     meaning of Code Section 409A and applicable Treasury regulations, such
     deferred compensation will be paid to the Employee within 2 1/2 months
     after the end of the calendar year in which it is payable, unless such
     bonus or incentive compensation is deferred pursuant to a timely election
     into a plan that complies with Code Section 409A.

     2.   Section 7.1 is amended and restated in its entirety as follows:

<PAGE>

          7.1 Disability. In the event the Employee shall become Disabled (as
     hereinafter defined) during the Employment Period, the Bank or the Company
     may terminate the Employee's employment under this Agreement by giving him
     written notice of such termination ("Disability Termination Notice"). In
     the event of any such termination during the Employment Period, the Bank
     shall continue to pay the Employee his Base Cash Compensation, at the rate
     in effect immediately prior to the giving of the Disability Termination
     Notice, through the end of the Employment Period (through the Termination
     Date then in effect). In addition, the Employers shall cover the Employee
     under their disability plans, if any, in effect from time to time under the
     terms and conditions that such coverage is made available to other
     employees of the respective Employers, and the Employee shall be entitled
     to any benefits payable to him under such disability plans. While disabled,
     the Bank shall continue to provide the Employee and his dependents with
     coverage under its Life, Disability and Medical Plans until the Employee
     reaches the age of sixty-five (65) years old to the extent that it may do
     so under the provisions of such plans, with the Employee's contributions to
     the premiums under such plans being no more than the amounts he paid for
     such premiums prior to his disability, adjusted from time to time for
     normal periodic increases in such premiums applied in general to employees
     of the Bank.

          The Employee shall be "Disabled" for purposes of this Agreement if the
     Employee (i) is unable to engage in any substantial gainful activity by
     reason of any medically determinable physical or mental impairment which
     can be expected to result in death or can be expected to last for a
     continuous period of not less than 12 months; or (ii) is, by reason of any
     medically determinable physical or mental impairment that can be expected
     to result in death or can be expected to last for a continuous period of
     not less than 12 months, receiving income replacement benefits for at least
     three (3) months from an Employer's long-term disability policy. The
     Employee shall be deemed to be Disabled if he is determined to be totally
     disabled by the Social Security Administration.

     3.   A new Section 9A is added as follows:

          9A. Delay in Severance Payments. If the Employee is a Specified
     Employee (as hereinafter defined) on the date of termination of employment,
     then the 18 monthly installments of severance pay described in Sections
     8.5(b) and 9 shall be payable as follows. No payments of the monthly
     installments shall be made within six months after the Employee's
     termination of employment. On the first business day of the seventh month
     after the date on which termination of employment occurs, the Bank shall
     pay to the Employee an amount equal to the sum of seven (7) equal monthly
     installments. The remaining monthly installments shall be paid on the first
     business day of each month thereafter.

          The Employee is a "Specified Employee" if he is a "key employee" (as
     defined in Code Section 416(i) without regard to Code Section 416(i)(5))
     and the stock of the Bank or the Company is publicly traded on an
     established securities market or otherwise on the date of termination of
     employment. The Employee is a "key employee" during the period described
     below if he is one of the following during the 12-month period ending on
     any December 31 (the "identification date"):

          (a) an officer of the Bank or the Company with annual compensation
          greater than $130,000 (as indexed pursuant to Code Section 416(i)(1)
          -- $140,000 for 2006), provided, that no more than 50 employees (or,
          if less, the greater of 3 employees or 10% of the employees) shall be
          treated as officers;

          (b) a five percent (5%) owner of the Bank or the Company; or

          (c) a one percent (1%) owner of the Bank or the Company with annual
          compensation of more than $150,000.

          If the Employee is a "key employee" as of an identification date, he
     is treated as a Specified Employee for the 12-month period beginning on the
     first day of the fourth month following the identification date.

<PAGE>

     4.   Section 8.5(e) is amended and restated in its entirety as follows:

          (e) $10,000 for out-placement, interim office, and related expenses,
     payable within thirty (30) days after the effective date of the termination
     of employment.

     5.   Except as amended herein, the Employment Agreement shall remain in
          full force and effect.

     The parties have executed this Amendment as of the day and year first above
written.
