EXECUTIVE and SENIOR OFFICER INCENTIVE COMPENSATION PLAN
 BASIC PLAN
 1.
    
    PURPOSEThe purpose of the Executive and Senior Management Incentive Compensation Plan (the Plan)
is to maximize the achievement of Mercantile Bancorp, Inc. (the Company) and its affiliate
banks objectives by providing incentives and awards to those senior-level executives and
officers who attain and sustain consistently high levels of performance which exceed normal
expectations and which contribute to the success and profitability of the bank or the
Company. The Plan is designed to support the key goals and objectives of each bank and the
Company.2.
    
    GENERAL DESCRIPTIONIncentive awards can be based on individual and/or organization-wide contributions to
performance as measured by critical operating ratios, including selected financial ratios,
percentage improvements and overall profitability. At the same time, the Plan establishes
annual targets which will help the bank and Company achieve its strategic goals, as well as
provide a performance review and measurement system.The incentive formulas are constructed to provide awards consistent with the increase in
profits to the banks and Company. The incentive formulas are designed to provide a level
of performance award that is competitive with comparable levels of performance in other
institutions, to assist the banks and Company in retaining and motivating key executives,
and to provide incentive toward the banks and Company continued growth and profitability.An earned incentive bonus is to be supplemental compensation in the form of cash paid on an
annual basis. The Plan is established in addition to regular salary and other benefits
programs. The Plan presumes an equitable base compensation system and a competitive
benefits program.3.
    
    ADMINISTRATIONThe Board of Directors of the Company has the responsibility to interpret, administer, and
amend the Plan.

Matters before the Board shall be decided based upon the vote of a majority of the entire
Board. Company officers who are members of the Board shall not be entitled to vote on
matters relating to the eligibility for and/or determination of their own incentive
compensation award.Prior to the beginning of each fiscal year, the Compensation Committee shall review and
revise, if deemed advisable, the guidelines for implementing the Plan for the coming fiscal
year.Computation of incentive awards will be performed by executive and or senior management at
the Company level and reviewed by the Compensation Committee.The Board may deem to exclude extraordinary occurrences, which could impact the incentive
awards, either positively or negatively, but are, by their nature, outside the significant
influence of Plan participants.The actions of the Board as to the interpretation, construction, and administration of the
Plan shall be final and binding for all parties, including the Company and its employees.In all cases, the Board of Directors reserves the right to reduce, modify, withhold or
discontinue awards to some or all eligible participants at any time without notice.4.
    
    PARTICIPANTSEligibility for participation in the Plan shall be limited to those individuals approved by
the CEO of the Company who, in unison with the judgment of the Compensation Committee and
the Board of Directors agree, are responsible for directing functions in each bank or the
Company that have a significant bearing on the growth and profitability of the Company.Participants in this Plan are not eligible for and will not participate in the Company
Performance Compensation Plan.Prior to the beginning of each Plan year, participants may be added or deleted at the
discretion of the CEO. In the event of a promotion from a Performance Pay Plan eligible
position to an ExSO Plan eligible position the timing of the transfer from one incentive
plan to the other will be at the Board of Directors discretion.5.

guidelines, the following definitions shall apply:

    INCENTIVE COMPUTATION  GENERAL PROCEDURESThe general formula for converting overall Company results into individual incentive awards
is as follows:
 
    
    Incentive dollars for a participant for the Plan year are calculated by:
 -
    
    The base annual salary of the participant,-
    
    Times the Percentage of the Base Award,-
    
    Times the Individual Performance Adjustment. (Discretionary)-
    
    Equals the Total Possible Incentive Award,-
    
    Neutral effect or Minus (-) the sum of the measures on each Key
Performance Factor and its weighting applicable to the participants Plan for that
year,-
    
    Equals the Total Actual Payout
 No incentive awards will be granted for a fiscal year, regardless of performance on
individual Key Performance Factors, if the individuals Threshold Performance Trigger is
not met for that fiscal year.At the discretion of the Compensation Committee of the Company, the calculation of the
incentive compensation award may also include a discretionary incentive award adjustment
(noted above as the Individual Performance Adjustment).7.
    
    PAYMENT OF INDIVIDUAL INCENTIVE COMPENSATION AWARDSWhen the Companys year-end financial results are known, participants will receive the
incentive payment determined by evaluating their performance for the year using the formula
established for their Plan. An award payout, if earned, would be made following the Plan
year-end when final audited numbers are finalized and available. Applicable withholding of
taxes will be deducted from each payment.In all cases, the Board of Directors reserves the right to reduce, modify, withhold or
discontinue awards to some or all eligible participants at any time without notice.

be considered to have earned one-twelfth of the annual incentive compensation award of a
particular year for each full month of employment in the fiscal year of his/her retirement
or death.If a participant dies, any unpaid incentive awards shall be paid to the estate, or
designated beneficiary, in one lump sum.Participants may not be added to the Plan after September 1 of the Plan year. If an
individual becomes a new participant prior to September 1 during the Plan year, the
incentive compensation award will be earned on the basis of one-twelfth of the annual
incentive compensation for each full month of participation.In all other cases of termination, the employee forfeits any unpaid awards.
 9.
