based on the recommendation of the Compensation Committee of the Board of
Directors (the &#8220;Board&#8221;) of Enterprise Financial Services Corp (the &#8220;Company&#8221;),
the Board took actions to implement a salary stock plan for the Company&#8217;s Chief
Executive Officer, Mr. Peter Benoist. The salary stock plan is intended to align
Mr. Benoist&#8217;s interests with those of the Company&#8217;s stockholders and to comply
with the Interim Final Rule on TARP Standards for Compensation and Corporate
Governance.</font></div>

2010, Mr. Benoist will receive salary stock at a rate of $120,000 per year in
pro-rated installments on the date that Mr. Benoist&#8217;s salary is payable in
accordance with the Company&#8217;s payroll practices then in effect. The number of
shares of salary stock issued to Mr. Benoist in each installment will equal the
dollar value of such installment divided by the closing price of the Company&#8217;s
stock on the Nasdaq Global Select Market on the date of the installment, net of
applicable withholding. The shares of salary stock will be fully vested and
subject to restrictions on transfer for a period of two years from the date of
issuance. The salary stock program will terminate at the time that the Company
is no longer subject to the incentive compensation restrictions of the TARP
standards. </font></div>
