Trading Arrangements, by Individual |  |
Material Terms of Trading Arrangement |  | During the quarterly period covered by this report, Linda C. Burkly, Ph.D., our Chief Scientific Officer, entered into a Rule 10b5-1 trading arrangement that is intended to qualify as an “eligible sell-to-cover transaction” (as described in Rule 10b5-1(c)(1)(ii)(D)(3) under the Exchange Act). This sell-to-cover arrangement, which was adopted on July 3, 2023, applies to restricted stock units (“RSUs”), whether vesting is based on the passage of time and/or the achievement of performance goals, granted on her start date, July 24, 2023, and any RSUs that may be granted from time to time thereafter (other than those which by their terms require us to withhold shares for tax withholding obligations in connection with vesting and settlement). This arrangement provides for the automatic sale of shares of our common stock that would otherwise be issuable on each settlement date of a covered RSU in an amount necessary to satisfy the applicable withholding obligation, with the proceeds of the sale delivered to us in satisfaction of the applicable withholding obligation. The number of shares that will be sold under this arrangement is not currently determinable as the number will vary based on the extent to which vesting conditions are satisfied, the market price of our common stock at the time of settlement and the potential future grant of additional RSUs subject to this arrangement.
