Item 5.02.
Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.
On December 29, 2016, First Business Bank (the “Bank”), a wholly owned subsidiary of First Business Financial Services, Inc. (the “Company”), entered into an amendment to its employment agreement with Corey Chambas, the Company’s President and Chief Executive Officer. The amendment eliminated Mr. Chambas’s right to receive a severance payment if he voluntarily resigns his employment during the three months following a Change in Control (as defined in the employment agreement), which is commonly referred to as a “modified single trigger” provision.
In addition, the amendment modified the constructive discharge provisions of the employment agreement to more closely reflect safe harbor provisions under applicable U.S. Treasury regulations. In particular, if there is a Change in Control followed by either (i) a material diminution in his salary, bonus or other compensation, (ii) a material diminution in his authority, duties or responsibilities, (iii) a requirement that he report to anyone other than the board of directors, (iv) a material diminution in the budget over which he retains authority, (v) a relocation of his primary office location to a new location that is more than 30 miles away from the current office location, or (vi) a material breach of the employment agreement by the Bank (or any successor thereto), then, in each case, Mr. Chambas will be entitled to receive a cash severance payment if he resigns within 90 days after such triggering event and within two years after the applicable Change in Control, subject to certain notice requirements and cure rights.
The foregoing description of the amendment is qualified in its entirety by reference to the full text of the amendment, which is attached hereto as Exhibit 10.1 and incorporated herein by reference.
