Explanation of Responses:

1. Each of the phantom stock units is the economic equivalent of one share of the common stock of the Issuer ("NCC").

2. Although the reporting person became irrevocably bound to dispose of shares of NCC in connection with the merger of NCC with and into CenterState Bank Corporation ("CenterState"), with CenterState as the surviving company (the "Merger"), on the closing date of the Merger, March 29, 2019, none of the transactions reported in this Form 4 occurred until the effective time of the Merger (12:01 a.m. Eastern Time on April 1, 2019) (the "Effective Time").

3. Pursuant to the Agreement and Plan of Merger by and between NCC and CenterState, dated November 23, 2018, the deferrals of NCC common stock representing equity awards and director fees credited to participant accounts under the National Commerce Corporation Deferral of Compensation Plan for Key Employees and Non-Employee Directors were converted into the right to receive 1.65 shares of CenterState common stock in respect of each such deferred share at the Effective Time, with cash payable in lieu of any fractional shares.
