                               EXECUTIVE SEVERANCE
                                    PAY PLAN

                                  INTRODUCTION

         The purpose of the Mercantile Bank Executive Severance Pay Plan (the
"Plan") is to enable Mercantile Bank (the "Company") to offer a form of
protection to the officers and other key employees of the Company and its
Affiliates in the event their employment with the Company and its Affiliates
terminates.

         Accordingly, the Company's Board of Directors, upon the recommendation
of the Compensation Committee, has adopted this Plan effective May 30, 2000 for
selected officers and key employees of the Company and its Affiliates in an
effort to assist in replacing the loss of income caused by a termination of
employment under the circumstances described herein.

         Except as specifically provided herein with respect to individual
employment agreements and any agreements providing payments in connection with a
change of control of the Company, this Plan amends and supersedes any severance
plans, policies and/or practices of the Company in effect for employees who
participate in the Plan.

employment is terminated by reason of his or her death, Disability or
Retirement, the Participant (or the Participant's surviving spouse or other
beneficiary as so designated by the Participant during his or her lifetime, or

other payments or benefits, to all Accrued Obligations.

     3.2 QUALIFYING EVENTS. If a Qualifying Event occurs during the period
commencing one-hundred eighty (180) days prior to the effective date of a Change
in Control and terminating on the second anniversary of the effective date of a
Change in Control, the Participant shall be entitled, in lieu of any other
payments or benefits, to any Accrued Obligations and the following:

          (a) Continued payment of the Participant's Salary (in accordance with
the Company's normal payroll practices), at the highest annual rate in effect at
any time up to and including the Participant's Date of Termination, through the
end of the Severance Period;

          (b) To the extent participating on the Participant's Date of
Termination, continued coverage under the Company's medical, dental and group
term life insurance plans for the Participant and, if applicable, his family (or
the reimbursement for the costs of similar coverage if the Company is unable to
provide

                                       11
<PAGE>

coverage under the plans due to underwriting or plan restrictions or adverse tax
consequences to the Company or the Participant) through the end of the Severance
Period, at a monthly premium cost to the Participant at a rate equal to that
being paid by active senior management employees of the Company from time to
time, for equivalent coverage during the Severance Period; provided, however,
that except as such continuation rights are protected by law, participation in
such medical, dental and group term life insurance benefits shall
correspondingly cease at such time as the Participant becomes eligible for a
subsequent employer's medical, dental and/or life insurance coverage that
provides coverage similar to the Company's coverage (or would become eligible if
the Participant did not waive coverage) (the "Continued Insurance Coverage").

     3.3 OTHER TERMINATION CIRCUMSTANCES. If the Participant's employment is
terminated (i) by an Employer for Cause or (ii) by the Participant in a manner
not covered by Section 3.2, the Participant shall be entitled to his or her
Accrued Obligations and no further payments or benefits shall be due the
Participant from any Employer.

     3.4 BENEFIT REDUCTIONS AND OTHER LIMITATIONS.

          (a) EMPLOYMENT AGREEMENTS AND OTHER PAYMENTS. Any benefits (other than
Accrued Obligations) payable to a Participant under Section 3.2 of this Plan
shall be reduced by the amount of any other severance or termination payments
payable by the Employer to the Participant under any valid and enforceable
individual employment or severance agreement.

                                       12
<PAGE>

          (b) NON-COMPETE. Notwithstanding anything else herein, in the event
that the Committee shall determine, in its sole discretion, that a Participant
has engaged in Competition during the first twelve months of the Severance
Period, all benefits payable to the Participant under Section 3.2 of the Plan
shall cease and the Severance Period shall end as of the date the Participant
first engaged in such Competition. Any amounts paid after the date of such
Competition shall promptly be refunded to the Employer by the Participant. If
any restriction set forth in this Plan with regard to Competition is found by
any court of competent jurisdiction to be unenforceable because it extends for
too long a period of time or over too great a range of activities or in too
broad a geographic area, it shall be interpreted to extend over the maximum
period of time, range of activities or geographic area as to which it may be
enforceable.

          (c) NONSOLICITATION. As a condition of receiving benefits hereunder, a
Participant must agree that he or she shall not, for the Severance Period,
directly or indirectly solicit, induce, influence or attempt to solicit,
influence or induce, any employee, temporary employee, contractor, vendor or
supplier of any Employer to terminate their employment or other relationship
with such Employer.

     3.5 RELEASE. As a condition of receiving benefits hereunder, the
Participant shall be required to provide the Employer with a release of all
claims of any kind whatsoever against the Company and its Affiliates, their
officers, directors and employees, known or unknown, as of the date of his or
her termination of employment. The release shall be in such form as requested by
the Company.

                                       13
<PAGE>

     3.6 EXCISE TAX EQUALIZATION PAYMENT. In the event that a Participant
becomes entitled to payments and/or benefits which would constitute "parachute
payments" within the meaning of Section 280G(b)(2) of the Code, the provisions
of Exhibit C will apply.

                           ADMINISTRATION OF THE PLAN

     5.1 PLAN ADMINISTRATOR. The general administration of the Plan on behalf of
the Employers shall be placed with the Committee.

     5.2 REIMBURSEMENT OF EXPENSES OF PLAN COMMITTEE. The Company may, in its
sole discretion, pay or reimburse the members of the Committee for all
reasonable expenses incurred in connection with their duties hereunder.

     5.3 ACTION BY MAJORITY OF THE PLAN COMMITTEE. A majority of the members of
the Committee at the time in office may do any act that the Plan authorizes or
requires the Committee to do, and the action of such majority of the members
expressed from time to time by a vote at a meeting (which may be telephonic), or
in writing without a meeting, shall constitute the action of the Committee and
shall have the same effect for all purposes as if assented to by all the
members.

     5.4 INTERNAL STRUCTURE OF PLAN COMMITTEE. The Chairman of the Committee
shall be appointed by the Board, and the members of the Committee shall appoint
a secretary, who need not be a member of the Committee. The Committee may
appoint such subcommittees with such powers as it shall determine and, subject
to any restriction or qualification contained in the resolution of the Committee
establishing a subcommittee, any subcommittee shall have all the power

                                       16
<PAGE>

and authority of the Committee with regard to the Plan. The Chairman of the
Committee shall, if he or she elects, be the Chair of any such subcommittee,
otherwise the members of the subcommittee shall elect from their number a Chair.
The Committee may authorize one or more members of the Committee or any agent to
execute or deliver any instrument or make any payment in its behalf.

     5.5 DECISIONS OF PLAN COMMITTEE ARE BINDING ON ALL PERSONS. The Committee
(or its delegate) shall have the exclusive right, power, and authority, in its
sole and absolute discretion, to administer, apply and interpret the Plan and
any other Plan documents and to decide all matters arising in connection with
the operation or administration of the Plan. Without limiting the generality of
the foregoing, the Committee shall have the sole and absolute discretionary
authority: (a) to take all actions and make all decisions with respect to the
eligibility for, and the amount of, benefits payable under the Plan; (b) to
formulate, interpret and apply rules, regulations and policies necessary to
administer the Plan in accordance with its terms; (c) to decide questions,
including legal or factual questions, relating to the calculation and payment of
benefits under the Plan; (d) to resolve and/or clarify any ambiguities,
inconsistencies and omissions arising under the Plan or other Plan documents;
(e) to decide for purposes of paying benefits hereunder, whether, based on the
terms of the Plan, a termination of employment is for Good Reason or for Cause;

shall be final, binding and conclusive on all parties.

     5.6 DELEGATION OF AUTHORITY. The Committee may delegate any and all of its
powers and responsibilities hereunder to other persons by formal resolution
filed with and accepted by the Board. Any such delegation shall not be effective
until it is accepted by the Board and the persons designated and may be

     5.7 RETENTION OF PROFESSIONAL ASSISTANCE. The Committee may employ such
legal counsel, accountants and other persons as may be required in carrying out

     5.8 ACCOUNTS AND RECORDS. The Committee shall maintain such accounts and
records regarding the fiscal and other transactions of the Plan and such other
data as may be required to carry out its functions under the Plan and to comply
with all applicable laws.

     5.9 COMPLIANCE WITH APPLICABLE LAW. The Company shall be deemed the Plan
Administrator for the purposes of any applicable law and shall be responsible

     5.10 LIABILITY. No member of the Committee and no officer, director or
employee of the Company or any Affiliate shall be liable for any action or
inaction with respect to his or her functions under the Plan unless such action
or inaction is adjudged to be due to gross negligence, willful misconduct or
fraud. Further, no member of the Committee shall be personally liable merely by
virtue of any instrument executed by him or her or on his or her behalf as a
member of the Committee.

     5.11 INDEMNIFICATION. Each Employer shall indemnify, to the full extent
permitted by law and its Certificate of Incorporation and By-laws (but only to
the extent not covered by insurance) its officers and directors (and any
employee involved in carrying out the functions of such Employer under the Plan)
and each member of the Committee against any expenses, including amounts paid in
settlement of a liability, which are reasonably incurred in connection with any
legal action to which such person is a party by reason of his or her duties or
responsibilities with respect to the Plan, except with regard to matters as to
which he or she shall be adjudged in such action to be liable for gross
negligence, willful misconduct or fraud in the performance of his or her duties.

     5.12 CLAIMS PROCEDURE. Any claim by a Participant or Beneficiary
("Claimant") with respect to eligibility, participation, contributions, benefits
or other aspects of the operation of the Plan shall be made in writing to the
Secretary of the Company or such other person designated by the Committee from
time to time for such purpose. If the designated person receiving a claim
believes, following

                                       19
<PAGE>

consultation with the Chairman of the Committee, that the claim should be
denied, he or she shall notify the Claimant in writing of the denial of the
claim within ninety (90) days after his or her receipt thereof (this period may
be extended an additional ninety (90) days in special circumstances and, in such
event, the Claimant shall be notified in writing of the extension). Such notice
shall (a) set forth the specific reason or reasons for the denial making
reference to the pertinent provisions of the Plan or of Plan documents on which
the denial is based, (b) describe any additional material or information
necessary to perfect the claim, and explain why such material or information, if
any, is necessary, and (c) inform the Claimant of his or her right pursuant to
this Section 5.12 to request review of the decision.

         A Claimant may appeal the denial of a claim by submitting a written
request for review to the Committee, within sixty (60) days after the date on
which such denial is received. Such period may be extended by the Committee for
good cause shown. If the Claimant fails to appeal the denial of a claim within
such sixty (60) day period (or such later date for filing an appeal as was
granted by the Committee for good cause), the Committee's denial of the claim
shall become conclusive and binding on all parties.

         If the Claimant does appeal the denial within the appropriate
timeframe, the claim will then be reviewed by the Committee. A Claimant or his
or her duly authorized representative may discuss any issues relevant to the
claim, may review pertinent documents and may submit issues and comments in
writing. If the

                                       20
<PAGE>

Committee deems it appropriate, it may hold a hearing as to a claim. If a
hearing is held, the Claimant shall be entitled to be represented by counsel.
The Committee shall decide whether or not to grant the claim within sixty (60)
days after receipt of the request for review, but this period may be extended by
the Committee for up to an additional sixty (60) days in special circumstances.
Written notice of any such special circumstances shall be sent to the Claimant.
Any claim not decided upon in the required time period shall be deemed denied.
All interpretations, determinations and decisions of the Committee with respect
to any claim shall be made in its sole discretion based on the Plan and other
relevant documents and shall be final, conclusive and binding on all persons.

                            AMENDMENT AND TERMINATION

     6.1 AMENDMENT AND TERMINATION. The Company reserves the right, in its sole
and absolute discretion, to amend, terminate or modify this Plan, in whole or in
part, by action of the Board (or a duly authorized committee thereof) at any
time and for any reason, provided that any amendment, termination or
modification of the Plan shall not reduce the payment or benefits to which a
Participant (and if applicable, the Participant's family) is entitled under the
terms of the Plan as in effect immediately prior to the amendment, termination
or modification. Following a Change in Control, this Plan may not be amended,
modified or terminated, in whole or in part, with respect to any individuals who
were Participants prior to the Change in Control.

     6.2 EFFECT OF TERMINATION. Upon termination of the Plan, the Plan shall
remain in effect for the limited purpose of paying benefits that have prior
thereto become due under the Plan.

                     PARTICIPATING EMPLOYERS AND SUCCESSORS

     7.1 PARTICIPATING EMPLOYERS. Upon approval by the Committee, this Plan may
be adopted by any Affiliate of the Company. Upon such adoption, the Affiliate
shall become an Employer hereunder and the provisions of the Plan shall be fully
applicable to the Employees of that Affiliate. If the Affiliate ceases to
qualify as an Affiliate under Section 1.2 of the Plan, it may by written
agreement, but shall not be obligated to, continue the Plan as a separate plan
and all reference to the "Company" shall become reference to the Affiliate. If
this Plan is not specifically continued by the Affiliate, it shall terminate as
to Employees of such Affiliate. If this Plan is specifically continued by the
Affiliate, the Affiliate, but not the Company, shall be liable to the Employees
of the Affiliate for any benefits due hereunder.

     7.2 SUCCESSORS. Subject to Section 6.1 hereof, the Company shall use its
best efforts to require any successor or assignee, whether direct or indirect,
by purchase, merger, consolidation or otherwise, to all or substantially all the
business or assets of the Company, expressly and unconditionally to assume and
agree to perform the Company's obligations under this Plan, in the same manner
and to the same extent that the Company would be required to perform if no such
succession or assignment had taken place. In such event, the term "Company", as
used in this Plan, shall mean the Company as hereinbefore defined and any

                                       23
<PAGE>

successor or assignee to the business or assets which by reason hereof becomes
bound by the terms and provisions of this Plan.

                                  ARTICLE VIII

                                  MISCELLANEOUS

     8.1 CONFIDENTIAL INFORMATION.

          (a) A Participant shall hold in a fiduciary capacity for the benefit
of the Employer all secret or confidential information, knowledge or data
relating to the Employer and its respective businesses, (i) obtained by the
Employee during his or her employment by the Employer and (ii) not otherwise
public knowledge or known within the Employer's industry. After termination of
the Participant's employment with the Employer, the Participant shall not,
without prior written consent of the Employer, unless compelled pursuant to the
order of a court or other body having jurisdiction over such matter, communicate
or divulge any such information, knowledge or data to anyone other than the
Employer and those designated by it.

          (b) In the event of a possible breach of (a) above, each Participant
will acknowledge, as a condition to the receipt of benefits under this Plan,
that damages may not be an adequate remedy and agree that the Employer may
obtain injunctive relief (in addition to its other remedies).

     8.2 RIGHTS OF EMPLOYEES. Nothing herein contained shall be held or
construed to create any liability or obligation upon the Employer to retain any
Employee in its service. All Employees shall remain subject to discharge or
discipline to the same extent as if the Plan had not been put into effect.

                                       25
<PAGE>

     8.3 ACCELERATION. The Company reserves the right, but has no obligation, to
accelerate any payments due hereunder and to pay such benefits at any time in a
lump sum.

     8.4 HEADINGS. The headings of the Plan are inserted for convenience of
reference only and shall have no effect upon the meaning of the provisions
hereof.

     8.5 USE OF WORDS. Whenever used in this instrument, a masculine pronoun
shall be deemed to include the masculine and feminine gender, and a singular
word shall be deemed to include the singular and plural, in all cases where the
context so requires.

     8.6 CONTROLLING LAW. The construction and administration of the Plan shall
be governed by the Employee Retirement Income Security Act of 1974, as amended.
To the extent not so governed, it shall be governed by the laws of the State of
Florida (without reference to its conflict of law provisions).

     8.7 WITHHOLDING. The Employer shall have the right to make such provisions
as it deems necessary or appropriate to satisfy any obligations it reasonably
believes it may have to withhold federal, state or local income or other taxes
incurred by reason of payments pursuant to this Plan.

     8.8 SEVERABILITY. Should any provisions of the Plan be deemed or held to be
unlawful or invalid for any reason, such fact shall not adversely affect the
other provisions of the Plan unless such determination shall render impossible
or impracticable the functioning of the Plan, and in such case, an appropriate

                                       26
<PAGE>

provision or provisions shall be adopted so that the Plan may continue to
function properly.

     8.9 INCOMPETENCY. In the event that the Committee finds that a Participant
(or designated beneficiary) is unable to care for his or her affairs because of
illness or accident, then benefits payable hereunder, unless claim has been made
therefor by a duly appointed guardian, committee, or other legal representative,
may be paid in such manner as the Committee shall determine, and the application
thereof shall be a complete discharge of all liability for any payments or
benefits to which such Participant (or designated beneficiary) was or would have
been otherwise entitled under this Plan.

     8.10 PAYMENTS TO A MINOR. Any payments to a minor from this Plan may be
paid by the Committee in its sole and absolute discretion (a) directly to such
minor; (b) to the legal or natural guardian of such minor; or (c) to any other
person, whether or not appointed guardian of the minor, who shall have the care
and custody of such minor. The receipt by such individual shall be a complete
discharge of all liability under the Plan therefor.

     8.11 ASSIGNMENT AND ALIENATION. The benefits payable under the Plan shall
not be subject to alienation, transfer, assignment, garnishment, execution or
levy of any kind, and any attempt to cause any benefits to be so subjected

                                       27

                               EXCISE TAX GROSS UP

          (a) In the event that a Participant shall become entitled to payments
and/or benefits provided by this Plan or any other amounts in the "nature of
compensation" (whether pursuant to the terms of this Plan or any other plan,
arrangement or agreement with the Company, any person whose actions result in a
change of ownership or effective control covered by Section 280G(b)(2) of the
Code or any person affiliated with the Company or such person) as a result of
such change in ownership or effective control (collectively, the "Company
Payments"), and such Company Payments will be subject to the tax (the "Excise
Tax") imposed by Section 4999 of the Code (and any similar tax that may
hereafter be imposed by any taxing authority), the Company shall pay to the
Participant at the time specified in subsection (d) below an additional amount
(the "Gross-up Payment") such that the net amount retained by the Participant,
after deduction of any Excise Tax on the Company Payments and any U.S. federal,
state, and for local income or payroll tax upon the Gross-up Payment provided
for by this paragraph (a), but before deduction for any U.S. federal, state, and
local income or payroll tax on the Company Payments, shall be equal to the
Company Payments.

          (b) For purposes of determining whether any of the Company Payments
and Gross-up Payments (collectively the "Total Payments") will be subject to the
Excise Tax and the amount of such Excise Tax, (i) the Total Payments shall be
treated as "parachute payments" within the meaning of Section 280G(b)(2) of the
Code, and all "parachute payments" in excess of the "base amount" (as defined
under Code Section 280G(b)(3) of the Code) shall be treated as subject to the
Excise Tax, unless and except to the extent that, in the opinion of the
Company's independent certified public accountants appointed prior to any change
in ownership (as defined under Code Section 280G(b)(2)) or tax counsel selected
by such accountants (the "Accountants"), such Total Payments (in whole or in
part) either do not constitute "parachute payments," represent reasonable
compensation for services actually rendered within the meaning of Section
280G(b)(4) of the Code in excess of the "base amount" or are otherwise not
subject to the Excise Tax, and (ii) the value of any non-cash benefits or any
deferred payment or benefit shall be determined by the Accountants in accordance
with the principles of Section 280G of the Code.

          (c) For purposes of determining the amount of the Gross-up Payment,
the Participant shall be deemed to pay U.S. federal income taxes at the highest
marginal rate of U.S. federal income taxation in the calendar year in which the
Gross-up Payment is to be made and state and local income taxes at the highest

                                       31
<PAGE>

marginal rate of taxation in the state and locality of the Participant's
residence for the calendar year in which the Company Payment is to be made, net
of the maximum reduction in U.S. federal income taxes which could be obtained
from deduction of such state and local taxes if paid in such year. In the event
that the Excise Tax is subsequently determined by the Accountants to be less
than the amount taken into account hereunder at the time the Gross-up Payment is
made, the Participant shall repay to the Company, at the time that the amount of
such reduction in Excise Tax is finally determined, the portion of the prior
Gross-up Payment attributable to such reduction plus the portion of the Gross-up
Payment attributable to the Excise Tax and U.S. federal, state and local income
tax imposed on the portion of the Gross-up Payment being repaid by the
Participant if such repayment results in a reduction in Excise Tax or a U.S.
federal, state and local income tax deduction), plus interest on the amount of
such repayment at the rate provided in Section 1274(b)(2)(B) of the Code.
Notwithstanding the foregoing, in the event any portion of the Gross-up Payment
to be refunded to the Company has been paid to any U.S. federal, state and local
tax authority, repayment thereof (and related amounts) shall not be required
until actual refund or credit of such portion has been made to the Participant,
and interest payable to the Company shall not exceed the interest received or
credited to the Participant by such tax authority for the period it held such
portion. The Participant and the Company shall mutually agree upon the course of
action to be pursued (and the method of allocating the expense thereof) if the
Participant's claim for refund or credit is denied.

          In the event that the Excise Tax is later determined by the Accountant
or the Internal Revenue Service to exceed the amount taken into account
hereunder at the time the Gross-up Payment is made (including by reason of any
payment the existence or amount of which cannot be determined at the time of the
Gross-up Payment), the Company shall make an additional Gross-up Payment in
respect of such excess (plus any interest or penalties payable with respect to
such excess) at the time that the amount of such excess is finally determined.

          (d) The Gross-up Payment or portion thereof provided for in subsection
(c) above shall be paid not later than the thirtieth (30th) day following an
event occurring which subjects the Participant to the Excise Tax; provided,
however, that if the amount of such Gross-up Payment or portion thereof cannot
be finally determined on or before such day, the Company shall pay to the
Participant on such day an estimate, as determined in good faith by the
Accountant, of the minimum amount of such payments and shall pay the remainder
of such payments (together with interest at the rate provided in Section
1274(b)(2)(B) of the Code), subject to further payments pursuant to subsection
(c) hereof, as soon as the amount thereof can reasonably be determined, but in
no event later than the

                                       32
<PAGE>

ninetieth day after the occurrence of the event subjecting the Participant to
the Excise Tax. In the event that the amount of the estimated payments exceeds
the amount subsequently determined to have been due, such excess shall
constitute a loan by the Company to the Participant, payable on the fifth day
after demand by the Company (together with interest at the rate provided in
Section 1274(b)(2)(B) of the Code).

          (e) In the event of any controversy with the Internal Revenue Service
(or other taxing authority) with regard to the Excise Tax, the Participant shall
permit the Company to control issues related to the Excise Tax (at its expense),
provided that such issues do not potentially materially adversely affect the
Participant, but the Participant shall control any other issues. In the event
the issues are interrelated, the Participant and the Company shall in good faith
cooperate so as not to jeopardize resolution of either issue, but if the parties
cannot agree, the Participant shall make the final determination with regard to
the issues. In the event of any conference with any taxing authority as to the
Excise Tax or associated income taxes, the Participant shall permit the
representative of the Company to accompany the Participant, and the Participant
and the Participant's representative shall cooperate with the Company and its
representative.

          (f) The Company shall be responsible for all charges of the
Accountant.

          (g) The Company and the Participant shall promptly deliver to each
other copies of any written communications and summaries of any verbal
communications with any taxing authority regarding the Excise Tax covered by
this Exhibit B.
