The Company’s 2017 Equity Incentive Plan (“2017 Plan”) provides for the issuance of restricted shares and stock options to employees, directors, and consultants of the Company. Effective October 1, 2021, no shares were available for issuance under the 2016 Equity Incentive Plan. Inducement Plan In addition to the Company’s 2017 Plan, the Company adopted the NeuroOne Medical Technologies Corporation 2021 Inducement Plan (the “Inducement Plan”) on October 4, 2021, 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. The Inducement Plan was approved by the Company’s Board of Directors without stockholder approval in accordance with such rule. Evergreen provision Under the 2017 Plan, the shares reserved automatically increase on January 1st of each year, for a period of not more than ten years from the date the 2017 Plan is approved by the stockholders of the Company, commencing on January 1, 2019 and ending on (and including) January 1, 2027, to an amount equal to 13% of the fully-diluted shares outstanding as of December 31st of the preceding calendar year. Notwithstanding the foregoing, the Board may act prior to January 1st of a given year to provide that there will be no January 1st increase in the share reserve for such year or that the increase in the share reserve for such year will be a lesser number of shares of common stock than would otherwise occur pursuant to the preceding sentence. “Fully Diluted Shares” as of a date means an amount equal to the number of shares of common stock (i) outstanding and (ii) issuable upon exercise, conversion or settlement of outstanding awards under the 2017 Plan and any other outstanding options, warrants or other securities of the Company that are (directly or indirectly) convertible or exchangeable into or exercisable for shares of common stock, in each case as of the close of business of the Company on December 31 of the preceding calendar year. On January 1, 2022 and 2021, 1,614,538 and 484,622 shares were added to the 2017 Plan, respectively, as a result of the evergreen provision.

The options granted have vesting periods ranging from being immediate to four years. All options expire ten years from the date of grant.
