Item 1.01. Entry into a Material Definitive Agreement.

        On December 14, 2005, First Business Financial Services, Inc. (“FBFS”) and its subsidiary, First Business Bank, entered into an amended and restated deferred compensation agreement (the “Agreement”) with Jerome J. Smith, its Chief Executive Officer. The Agreement provides an economic incentive in the form of retirement and death benefits for Mr. Smith to continue his employment. Under the Agreement, FBFS is obligated to require its successor to assume its obligations under the Agreement.

        In the event of termination of his employment for any reason other than cause (as defined in the Agreement), the Agreement provides that Mr. Smith will be entitled to deferred compensation equal to five times his average salary for three of the last five calendar years, less $200,000, payable over five years, and group health insurance plan continuation coverage for five years. The Agreement also provides that Mr. Smith will be entitled to a payment of $3,333.33 per month for up to 60 months for his compliance with a noncompete covenant for two years after the commencement of payment of any deferred compensation benefit under the agreement. If Mr. Smith dies while employed by FBFS or after his employment terminates for any reason other than for cause, his designated beneficiary will be entitled to a death benefit equal to $200,000, less any amounts paid with respect to the noncompete covenant, payable over five years, as well as any remaining deferred compensation payable as of the date of his death.

        The foregoing description of the Agreement is qualified in its entirety by reference to the full text of the Agreement, a copy of which is filed herewith as Exhibit 10.1 and is incorporated herein by reference.
