NOTE 12 – STOCKHOLDERS’ EQUITY

2016 Equity Plan

We maintained the 2016 Equity Incentive Plan (the “2016 Plan”) for employees, officers, directors and other entities and individuals whose efforts contribute to our success. The 2016 Plan terminated pursuant to its terms on December 31, 2020, although all outstanding awards on such date continue in full force and effect.

2021 Equity Plan

On May 12, 2021, the Board adopted, with shareholder approval as of July 15, 2021, 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.

General Description of the 2021 Plan

The following is a summary of the material provisions of the 2021 Plan and is qualified in its entirety by reference to the complete text of the 2021 Plan, which you are encouraged to read in full.

Administration

The 2021 Plan is administered by the Compensation Committee of the Board, which consists of three members of the Board, each of whom is a “non-employee director” within the meaning of Rule 16b-3 promulgated under the Exchange Act and an “outside director” within the meaning of Code Section 162(m). Among other things, the Compensation Committee has complete discretion, subject to the express limits of the 2021 Plan, to determine the directors, employees and nonemployee consultants to be granted an award, the type of award to be granted, the terms and conditions of the award, the form of payment to be made and/or the number of shares of Common Stock subject to each award, the exercise price of each option and base price of each stock appreciation right (“SAR”), the term of each award, the vesting schedule for an award, whether to accelerate vesting, the value of the Common Stock underlying the award, and the required withholding, if any. The Compensation Committee may amend, modify or terminate any outstanding award, provided that the participant’s consent to such action is required if the action would impair the participant’s rights or entitlements with respect to that award. The Compensation Committee is also authorized to construe the award agreements and may prescribe rules relating to the 2021 Plan. Notwithstanding the foregoing, the Compensation Committee does not have any authority to grant or modify an award under the 2021 Plan with terms or conditions that would cause the grant, vesting or exercise thereof to be considered nonqualified “deferred compensation” subject to Code Section 409A.

Grant of Awards; Shares Available for Awards

The 2021 Plan provides for the grant of stock options, SARs, performance share awards, performance unit awards, distribution equivalent right awards, restricted stock awards, restricted stock unit awards and unrestricted stock awards to non-employee directors, officers, employees and nonemployee consultants of the Company or its affiliates. We have reserved a total of 1,000,000 shares of Common Stock for issuance as or under awards to be made under the 2021 Plan. If any award expires, is cancelled, or terminates unexercised or is forfeited, the number of shares subject thereto is again available for grant under the 2021 Plan.

Stock Options

The 2021 Plan provides for either “incentive stock options” (“ISOs”), which are intended to meet the requirements for special federal income tax treatment under the Code, or “nonqualified stock options” (“NQSOs”). On May 12, 2021, the 2021 Plan was approved by the board of directors and by the shareholders on July 15, 2021. Stock options may be granted on such terms and conditions as the Compensation Committee may determine; provided, however, that the per share exercise price under a stock option may not be less than the fair market value of a share of the Company’s Common Stock on the date of grant and the term of the stock option may not exceed 10 years (110% of such value and five years in the case of an ISO granted to an employee who owns (or is deemed to own) more than 10% of the total combined voting power of all classes of capital stock of the Company or a parent or subsidiary of the Company). ISOs may only be granted to employees. In addition, the aggregate fair market value of our Common Stock covered by one or more ISOs (determined at the time of grant) which are exercisable for the first time by an employee during any calendar year may not exceed $100,000. Any excess is treated as a NQSO.

Stock Appreciation Rights

An SAR entitles the participant, upon exercise, to receive an amount, in cash or stock or a combination thereof, equal to the increase in the fair market value of the underlying Common Stock between the date of grant and the date of exercise. SARs may be granted in tandem with, or independently of, stock options granted under the 2021 Plan. An SAR granted in tandem with a stock option (i) is exercisable only at such times, and to the extent, that the related stock option is exercisable in accordance with the procedure for exercise of the related stock option; (ii) terminates upon termination or exercise of the related stock option (likewise, the Common Stock option granted in tandem with a SAR terminates upon exercise of the SAR); (iii) is transferable only with the related stock option; and (iv) if the related stock option is an ISO, may be exercised only when the value of the stock subject to the stock option exceeds the exercise price of the stock option. An SAR that is not granted in tandem with a stock option is exercisable at such times as the Compensation Committee may specify.

Performance Share and Performance Unit Awards

Performance share and performance unit awards entitle the participant to receive cash or shares of our Common Stock upon the attainment of specified performance goals. In the case of performance units, the right to acquire the units is denominated in cash values.

Restricted Stock Awards and Restricted Stock Unit Awards

A restricted stock award is a grant or sale of Common Stock to the participant, subject to our right to repurchase all or part of the shares at their purchase price (or to require forfeiture of such shares if issued to the participant at no cost) in the event that conditions specified by the Compensation Committee in the award are not satisfied prior to the end of the time period during which the shares subject to the award may be repurchased by or forfeited to us. Our restricted stock unit entitles the participant to receive a cash payment equal to the fair market value of a share of Common Stock for each restricted stock unit subject to such restricted stock unit award, if the participant satisfies the applicable vesting requirement.

Unrestricted Stock Awards

An unrestricted stock award is a grant or sale of shares of our Common Stock to the participant that is not subject to transfer, forfeiture or other restrictions, in consideration for past services rendered to the Company or an affiliate or for other valid consideration.

Amendment and Termination

The Compensation Committee may adopt, amend and rescind rules relating to the administration of the 2021 Plan, and amend, suspend or terminate the 2021 Plan, but no such amendment, rescission, suspension or termination will be made that materially and adversely impairs the rights of any participant with respect to any award received thereby under the 2021 Plan without the participant’s consent, other than amendments that are necessary to permit the granting of awards in compliance with applicable laws.

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. As of December 31, 2023 and December 31, 2022, respectively, there are zero 0 and zero 0 shares of Series B Convertible Preferred Stock issued and outstanding.

Each share of Series C Convertible Preferred Stock had 172 votes (subject to adjustment); provided that in no event may a holder of Series C Convertible Preferred Stock be entitled to vote a number of shares in excess of such holder’s Beneficial Ownership Limitation (as defined in the Certificate of Designation and as described below). Each share of Series C Convertible Preferred Stock was convertible, at any time and from time to time, at the option of the holder, into that number of shares of common stock (subject to the Beneficial Ownership Limitation) determined by dividing the stated value of such share ($1,000) by the conversion price, which is $5.50 (subject to adjustment). 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”). All holders of the Series C Preferred Stock elected the 19.99% Beneficial Ownership Limitation.

All holders of the Series D Preferred Stock elected the 19.99% Beneficial Ownership Limitation.

The existing investor’s Purchase Agreement also provides that the Company will not, with certain exceptions, sell or issue common stock or Common Stock Equivalents (as defined in the Purchase Agreement) on or prior to December 31, 2023 that entitles any person to acquire shares of common stock at an effective price per share less than the then conversion price of the Series E Convertible Preferred Stock without the consent of the Purchaser.

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 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.

In the year ended December 31, 2023, the Company issued 111,538 shares of common stock related to two transactions. For the six months ended June 30, 2023, the employee contributions for the first ESPP tranche totaled $117,048 and represented a purchase price of $1.79 per share for 65,561 shares. For the six-month period beginning July 1, 2023 and ending December 31, 2023 the employee contributions for the second ESPP tranche totaled $113,352 and represented a purchase price of $2.47 per share for 45,977 shares.
