Buy Plan / Sale Plan: These are also open market purchases/sales of shares, but in this case the transaction is part of a trading plan. Rule 10b5-1 allows insiders to setup a trading plan to buy/sell stocks over a certain period of time. Since the purchases/sales are predetermined, this protects the insiders from violating insider trading law.

Transaction was made pursuant to a contract, instruction or written plan for the purchase or sale of equity securities of the issuer that is intended to satisfy the affirmative defense conditions of Rule 10b5-1(c).

F3 On July 25, 2025 ("Grant Date"), the Company granted Mr. Hayden 70,000 restricted stock units ("RSUs") under the Company's 2020 Omnibus Incentive Plan.

The RSUs are performance-based and will vest in four tranches of 17,500 each upon the date the Board determines that the applicable performance condition has been achieved. In the event that the Performance Conditions are not met, the RSUs granted will vest in four equal installments of 17,500 on each on the first, second, third and fourth anniversaries of the Grant Date, and will be settled upon vesting (or within 30 days thereafter). All vesting events are subject to continued employment on each applicable vesting date.
