NOTE 5 – STOCKHOLDERS’ EQUITY 

Series B Convertible Preferred Stock

The following summary of certain terms and provisions of our Series B Convertible Preferred Stock (the “Series B Convertible Preferred Stock”) is subject to, and qualified in its entirety by reference to, the terms and provisions set forth in our certificate of designation of preferences, rights and limitations of Series B Convertible Preferred Stock (the “Series B Convertible Preferred Certificate of Designation”) as previously filed. Subject to the limitations prescribed by our articles of incorporation, our board of directors is authorized to establish the number of shares constituting each series of preferred stock and to fix the designations, powers, preferences, and rights of the shares of each of those series and the qualifications, limitations and restrictions of each of those series, all without any further vote or action by our stockholders. Our board of directors designated 15,000 of the 10,000,000 authorized shares of preferred stock as Series B Convertible Preferred Stock with a stated value of $1,000 per share. The shares of Series B Convertible Preferred Stock were validly issued, fully paid and non-assessable.

Each share of Series B Convertible Preferred Stock was convertible at any time at the holder’s option into a number of shares of common stock equal to $1,000 divided by the conversion price of $7.00 per share. Notwithstanding the foregoing, we could not effect any conversion of Series B Convertible Preferred Stock, with certain exceptions, to the extent that, after giving effect to an attempted conversion, the holder of shares of Series B Convertible Preferred Stock (together with such holder’s affiliates, and any persons acting as a group together with such holder or any of such holder’s affiliates) would beneficially own a number of shares of our common stock in excess of 4.99% (or, at the election of the purchaser, 9.99%) of the shares of our common stock then outstanding after giving effect to such conversion. The Series B Convertible Preferred Certificate of Designation does not prohibit the Company from waiving this limitation. Upon any liquidation, dissolution or winding-up of Company, whether voluntary or involuntary (a “Liquidation”), the holders shall be entitled to participate on an as-converted-to-common stock basis (without giving effect to the Beneficial Ownership Limitation) with holders of the common stock in any distribution of assets of the Company to the holders of the common stock.

The Company shall not effect any conversion of the Series C Convertible Preferred Stock, and a holder shall not have the right to convert any portion of the Series C Convertible Preferred Stock, to the extent that after giving effect to the conversion sought by the holder such holder (together with such holder’s Attribution Parties (as defined in the Certificate of Designation)) would beneficially own more than 4.99% (or upon election by a holder, 19.99%) of the number of shares of common stock outstanding immediately after giving effect to the issuance of shares of common stock issuable upon such conversion (the “Beneficial Ownership Limitation”).

Employee Stock Purchase Plan

In the fourth quarter of 2022, the board of directors adopted an Employee Stock Purchase Plan (“ESPP”) which was effective as of January 1, 2023 with a term of 10 years. The ESPP allows eligible employees to purchase shares of the Company's common stock at a discounted price, through payroll deductions from a minimum of 1% and up to 25% of their eligible compensation up to a maximum of $25,000 or the IRS allowable limit per calendar year. The Company’s Chief Financial Officer administers the ESPP in conjunction with approvals from the Company’s Compensation Committee, including with respect to the frequency and duration of offering periods, the maximum number of shares that an eligible employee may purchase during an offering period, and, subject to certain limitations set forth in the ESPP, the per-share purchase price. Currently, the maximum number of shares that can be purchased by an eligible employee under the ESPP is 10,000 shares per offering period and there are two six-month offering periods that begin in the first and third quarters of each fiscal year. The purchase price for one share of Common Stock under the ESPP is currently equal to 85% of the fair market value of one share of Common Stock on the first trading day of the offering period or the purchase date, whichever is lower (look-back feature). Although not required by the ESPP, all payroll deductions received or held by the Company under the ESPP are segregated and deemed as “restricted cash” until the completion of the offering period and redemption of the applicable shares and those withheld amounts are recorded as liabilities. The ESPP employee contribution for the three months ended March 31, 2024 is less than 2 % of total cash and is not deemed material, therefore it is not presented separately on the Balance Sheet as “restricted cash”. The maximum aggregate number of shares of the Common Stock that may be issued under the ESPP is 1,000,000 shares.

Under ASC 718-50 “Employee Share Purchase Plans” the plan is considered a compensatory plan and the compensation for each six-month offering period is computed based upon the grant date fair value of the estimated shares to be purchased based on the estimated payroll deduction withholdings. The grant date fair value was computed as the sum of (a) 15% purchase discount off of the grant date quoted trading price of the Company’s common stock and (b) the fair value of the look-back feature of the Company’s common stock on the grant date which consists of a call option on 85% of a share of common stock and a put option on 15% of a share of common stock.

As of the three months ended March 31, 2024, the Company has an accrued liability of $44,686 included in accrued expenses of employee contributions for the ESPP which may convert to shares of common stock upon the close of the offering period open from January 1, 2024 to June 30, 2024. The liability is offset by restricted cash held by the Company in the same amount for employee contributions which the Company expects to convert to common stock upon closure of the offering period at June 30, 2024. Additionally, the Company recorded a stock-based expense associated with the ESPP for the three months ended March 31, 2024 of $18,116.

The Company computed the fair value of the look-back feature call and put options for January 1, 2024 to March 31, 2024 using a Black Scholes option pricing model using the following assumptions:

During the offer period, the Company records stock-based compensation pro rata as an expense and a credit to additional paid-in capital. The following table discloses relevant information for the ESPP at March 31, 2024 and for three months then ended.

Stock-Based Compensation

Stock-based compensation expense recognized under ASC 718-10 for the three months ended March 31, 2024 and 2023, was $141,204 and $75,128, respectively, for stock options granted to employees. This expense is included in selling, general and administrative expenses in the unaudited consolidated statements of operations. Stock-based compensation expense recognized during the periods is based on the grant-date fair value of the portion of share-based payment awards that are ultimately expected to vest during the period. At March 31, 2024, the total compensation cost for stock options not yet recognized was $438,998. This cost will be recognized over the remaining vesting term of the options ranging from nine months to two and one-half years.

On May 12, 2021, the Board adopted, with shareholder approval, the 2021 Equity Incentive Plan (the “2021 Plan”) providing for the issuance of up to 1,000,000 shares of our common stock. The purpose of the 2021 Plan is to assist the Company in attracting and retaining key employees, directors and consultants and to provide incentives to such individuals to align their interests with those of our shareholders. During the third quarter of 2021, the shareholders approved the issuance of up to one million shares or share equivalents pursuant to the 2021 Plan. The Company filed an S-8 registration statement in concert with the 2021 Plan which was deemed effective on August 5, 2021. The plan covers a period of ten years.

As of March 31, 2024, and December 31, 2023, options to purchase a total of 1,387,775 (net of forfeitures discussed below) shares of common stock and 1,387,775 shares of common stock were outstanding, respectively. At March 31, 2024, 766,323 options were exercisable. Of the total options issued, 269,658 and 269,658 options were outstanding under the 2016 Equity Incentive Plan, 788,117 and 788,117 were outstanding under the 2021 Plan and a further 330,000 and 330,000 non-plan options to purchase common stock were outstanding as of March 31, 2024 and December 31, 2023, respectively. The non-plan options were granted to four executives as hiring incentives, including the Company’s CEO in the fourth quarter of 2020.
