QT Imaging Incentive Plan

In September 2021, the Board of Directors approved and the Company adopted the Plan (the “QT Imaging Plan”). The maximum aggregate number of shares of common stock that the Company may award under the QT Imaging Plan was 7,000,000. The term of the QT Imaging Plan was originally 10years. The QT Imaging Plan was administered by the compensation committee of the Company’s Board of Directors (the “Administrator”). The Company may grant awards to eligible participants which may take the form of stock options (both incentive stock options and non-qualified stock options), stock purchase rights, restricted stock, restricted stock units and performance stock awards. Awards may be granted to employees, directors, and consultants (as defined in the QT Imaging Plan.)
