Rule 10b5-1 and Non-Rule 10b5-1 Trading Arrangements

On December 6, 2023, Keith J. Allman, our President and Chief Executive Officer, adopted a new 10b5-1 Trading Plan that is intended to satisfy the affirmative defense of Rule 10b5-1(c) of the Exchange Act (the "Plan"). Trades under the Plan are permitted to begin on March 6, 2024 and the Plan's maximum duration is until October 31, 2024. The Plan is intended to allow for: (i) the sale of 56,676 shares, (ii) the exercise and sale of up to 1,162,972 stock options, and (iii) the sale of shares acquired by Mr. Allman upon the vesting of performance restricted stock units ("PRSUs") granted to him under our 2021-2023 Long Term Incentive Program (the number of PRSUs that vest is subject to certain performance conditions under the Long Term Incentive Program, with a maximum of 84,260 PRSUs).

During the three months ended December 31, 2023, none of our other officers or directors adopted or terminated any Rule 10b5-1 trading arrangement or non-Rule 10b5-1 trading arrangement.
