2025 Equity Incentive Plan On January 10, 2025, the Board of Directors of the Company adopted the NeuroOne Medical Technologies Corporation 2025 Equity Incentive Plan (the “2025 Plan”). On February 14, 2025, at the 2025 annual meeting of stockholders, the stockholders of the Company approved the 2025 Plan. The 2025 Plan is the successor to and continuation of the Company’s 2017 Equity Incentive Plan (the “2017 Plan”) and to the Company’s 2016 Equity Incentive Plan (the “Prior Plans”). As of the Effective Date, (i) no additional awards may be granted under the Prior Plans; (ii) any Returning Shares will become available for issuance pursuant to Awards granted under the 2025 Plan; and (iii) all outstanding awards granted under the Prior Plans will remain subject to the terms of the Prior Plans (except to the extent such outstanding awards result in returning shares that become available for issuance pursuant to awards granted under the 2025 Plan. Initially, the maximum number of shares of the Company’s Common Stock (the “Common Stock”), that may be issued under the 2025 Plan may not exceed (1) 3,000,000 and (2) any shares subject to outstanding stock awards under the NeuroOne Medical Technologies 2017 Equity Incentive Plan that are forfeited or otherwise returned to the share reserve. Inducement Plan In October 2021, the Company adopted the NeuroOne Medical Technologies Corporation 2021 Inducement Plan (the “Inducement Plan”), pursuant to which the Company reserved 420,350 shares of its common stock to be used exclusively for grants of awards to individuals who were not previously employees or directors of the Company, as an inducement material to the individual’s entry into employment with the Company within the meaning of Rule 5635(c)(4) of the Nasdaq Listing Rules.

On November 9, 2023, the Company’s Board of Directors adopted the First Amendment to the Company’s Inducement Plan, increasing the aggregate number of shares of common stock that may be issued pursuant to equity incentive awards under the Inducement Plan by 150,000 shares, and on May 20, 2025, the Board adopted the Second Amendment to the Company’s Inducement Plan, increasing the aggregate number of shares of common stock that may be issued pursuant to equity incentive awards under the Inducement Plan by an additional 575,000 shares. 2017 Plan and Evergreen Provision On January 1, 2025, 1,124,446 shares were added to the 2017 Plan as a result of the evergreen provision within the 2017 Plan.
