Rule10b5-1 Trading Plans

Our directors and executive officers* maypurchase or sell shares of our common stock in the market from time to time, including pursuant to equity trading plans adopted in accordance with Rule10b5*-1 under the Exchange Act and in compliance with guidelines specified by our insider trading policy. In accordance with Rule10b5-1 and our insider trading policy, directors, officers and certain employees who, at such time, arenot in possession of material non-public information are permitted to enter into written plans that pre-establish amounts, prices and dates (or formula for determining the amounts, prices and dates) of future purchases or sales of our stock, including shares acquired pursuant to our equity incentive plans. Under a Rule10b5-1 trading plan, a broker executes trades pursuant to parameters established by the director or executive officer when entering into the plan, without further direction from them. The use of these trading plans permits asset diversification as well as personal financial and tax planning. Our directors and executive officers also* maybuy or sell additional shares outside of a Rule10b5*-1 plan when they arenot in possession of material nonpublic information, subject to compliance with SEC rules, the terms of our insider trading policy and certain minimum holding requirements. The following table shows the Rule10b5-1 trading plans intended to satisfy the affirmative defense conditions of Rule10b-1(c) adopted or terminated by our directors and executive officers during thefourth quarter of fiscal2023.

No non-Rule 10b5-1 trading arrangements (as defined by Item408(a) of Regulation S-K) were entered into, adopted or terminated by any Section16 director or officer during thefourth quarter of fiscal2023.
