Item 5.02 Departure of Directors or Certain Officers; Election of Directors;
Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On April 10, 2009, the Board of Directors of First Business Financial Services, Inc. (the "Company") approved an amendment (the "Amendment") to the Company's Annual Incentive Bonus Plan (the "Plan"). Prior to the Amendment, the Plan provided that the Company and each of its subsidiaries (other than First Business Trust & Investments) use three equally-weighted performance measures:
(1) Return on Equity (for purposes of calculating the Company portion of the payout mix) or Return on Assets (for purposes of calculating a subsidiary's portion of the payout mix); (2) Net Interest Income plus Fee Income ("Top Line Growth") and (3) Adjusted Net Income (measured for the Company as Net Income pre-tax, pre-loan loss provision and after actual net charge offs, and measured for the subsidiaries as Net Income pre-tax, pre-allocation, pre-loan loss provision and after actual net charge offs). The Plan provided that First Business Trust & Investments use two equally-weighted performance measures: (1) Top Line Growth and (2) Adjusted Net Income (measured in the same manner as the other subsidiaries).

The Amendment replaced the Top Line Growth performance measure with a Net Income measure for the Company and each of its subsidiaries (including First Business Trust & Investment). The foregoing description of the Plan, as amended, is qualified in its entirety by reference to the full text of the Plan, as amended, a copy of which is filed herewith as Exhibit 10.1 and is incorporated herein by reference.
