On October 20, 2020 the Company and Mr. Douglas Bass, Executive Vice President and Chief Operating Officer, entered into a Retirement and Separation Agreement (the “Agreement”). Mr. Bass will retire from the Company on December 31, 2020 ("the Retirement Date"). The Agreement supersedes the previously reported Amended and Restated Employment Letter entered into between the Company and Mr. Bass dated August 5, 2019 and attached as Exhibit 10.1 to the Company's Form 8-K filed on August 9, 2019 (the "Original Agreement"), which is incorporated herein by reference.
Pursuant to the terms of the Agreement, Mr. Bass will receive a cash severance payment equal to twelve months of his current base salary to be paid in 26 bi-weekly installments starting after the Retirement Date. Mr. Bass will also be eligible to participate in the Company's health insurance plan, receive a Long Term Incentive ("LTI") award equal to $100,000 in GWB stock to be granted consistent with the terms and conditions of the LTI awards to be granted to the other Executive Officers of the Company in November of 2020, and all previously granted Short Term Incentive and LTI shall vest in accordance with the terms of the applicable award. Mr. Bass will not be granted any further cash incentive awards, stock options, restricted stock, performance share awards, or other equity or incentive awards other than as previously approved.
The Agreement contains customary terms applicable to the departure of an executive of the Company and confirms that certain provisions contained in the Original Agreement, including restrictions relating to confidentiality, disclosure of proprietary information, non-competition and non-solicitation, shall remain in full force and effect after the Retirement Date for timeframes as provided within the Original Agreement.
The above summary of the terms of the Agreement is not a complete description of the terms of the Agreement and such description is qualified in its entirety by reference to the full text of the Agreement which is filed as Exhibit 10.1 to this Current Report on Form 8-K.
