The Company’s 2016 and 2017 Equity Incentive Plans provide for the issuance of restricted shares and stock options to employees, directors, and consultants of the Company. The Company initially reserved 764,089 shares of common stock for issuance under the 2016 and 2017 Equity Incentive Plans on a combined basis. 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, 2021 and 2020, 484,622 and 428,930 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. The total expense for the years ended September 30, 2021 and 2020 related to the stock options was $983,301 and $798,242, respectively.
