Rule 10b5-1 Trading Arrangements

From time to time, members of the Company's Board of Directors and officers of the Company may enter into Rule 10b5-1 trading plans, which allow for the purchase or sale of common stock under pre-established terms at times when directors and officers might otherwise be prevented from trading under insider trading laws or because of self-imposed blackout periods. Such trading plans are intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) under the Exchange Act and comply with the Company's Insider Trading Policy. Other than as described below, during the three months ended March 31, 2024, none of the Company's directors or officers adopted, modified orterminated a “Rule 10b5-1 trading arrangement” or a “non-Rule 10b5-1 trading arrangement” as each term is defined under Item 408 of Regulation S-K.

On March 6, 2024, Jeffrey L. Gendell, Chairman and Chief Executive Officer of the Company, adopted a Rule 10b5-1 trading plan intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) under the Exchange Act. Sales under Mr. Gendell’s plan, which provides for the potential sale of up to an aggregate of 200,000 shares of the Company’s common stock, may commence as soon as 90 calendar days from the execution date of the trading plan and shall end, subject to certain conditions, on the earlier of (a) March 7, 2025 and (b) the date that all shares subject to the plan have been sold.
