(e) On September 21, 2016, Seacoast Banking Corporation of Florida (“Seacoast” or the “Company”) entered into a change in control employment agreement (“CIC Agreement”) with each of the following executive officers of Seacoast and its wholly-owned subsidiary Seacoast National Bank (“SNB”): Charles Cross, Commercial Banking Executive for SNB; David Houdeshell, Chief Risk Officer for Seacoast and SNB; and Charles Shaffer, Retail Banking Executive for SNB.

The CIC Agreement with each executive officer supersedes the previous change in control agreement between each individual and the Company dated October 28, 2014. The new CIC Agreement eliminates the excise tax gross-up payment contained in the 2014 agreements.

Each CIC Agreement has an initial term of one year and provides for automatic one-year extensions unless expressly not renewed. A change in control, as defined in the agreement, must occur during the period (the “Change in Control Period”) to trigger the agreement. The CIC Agreement provides that, once a change in control has occurred, the Company agrees to continue the employment of the executive subject to the contract (the “Executive”) for a one-year period, in a comparable position as the Executive held in the 120-day period prior to the change in control, and with the same annual base pay and target bonus opportunity. If the Executive is terminated “without cause” or resigns for “good reason,” as defined in the CIC Agreement, during the one-year period following a change in control, the Executive will receive 1) cash severance equal to a multiple (two times, for Mr. Cross and Mr. Shaffer, and one times for Mr. Houdeshell) of the sum of (i) Executive’s Annual Base Salary at the rate in effect on the date of termination, and (ii) the Executive’s average annual performance bonus for the last three full fiscal years prior to the date of termination (“Executive’s Average Annual Performance Bonus”); 2) a prorated final year bonus, based on the Executive’s Average Annual Performance Bonus; and 3) health and other welfare benefits, as defined in the agreement, for a period of time following termination (18 months or Mr. Cross and Mr. Shaffer, and 12 months for Mr. Houdeshell).

The Executive is required to execute a release of claims as a condition to receipt of severance under the CIC Agreement and is subject to protective covenants prohibiting the disclosure and use of the Company’s confidential information and, during the one-year period following a termination by the Company for any reason other than for death or disability, or by the Executive for Good Reason, as well as protective covenants regarding non-competition, non-solicitation of protected customers, non-solicitation of employees, and non-disparagement of the Company or its directors, officers, employees or affiliates.

The foregoing description of the CIC Agreement does not purport to be complete and is qualified in its entirety by reference to the CIC Agreement, which is filed as Exhibit 10.1 hereto, and is incorporated into this report by reference thereto.
