CAPITAL STOCK, STOCK PLANS, WARRANTS AND STOCK BASED COMPENSATION | NOTE 6 CAPITAL STOCK, STOCK PLANS, WARRANTS AND STOCK BASED COMPENSATION Stock Option Plans The Company’s 2003 Outside Directors Stock Plan, as amended (the “2003 Plan”) provides for the grant of Non-Qualified Stock Options (“NQSOs”) to member of the Company’s Board of Directors (the “Board”) who is not an employee of the Company or its subsidiaries (“Eligible Director”). The 2003 Plan also provides for the grant of an NQSO to purchase up to 10,000 shares of the Company’s Common Stock for each Eligible Director upon each re-election to the Board, and the grant of an NQSO to purchase up to 20,000 shares of the Company’s Common Stock upon initial election. NQSOs granted prior to July 20, 2021 have a vesting period of six months from the date of grant and a term of 10 years, with an exercise price equal to the closing trade price on the date prior to grant date. NQSOs granted on and after July 20, 2021 vest 25% per year, beginning on the first anniversary date of the grant and also have a term of 10 years, with an exercise price equal to the closing trade price on the date prior to grant date. Additionally, the 2003 Plan provides for the issuance to each Eligible Director a number of shares of the Company’s Common Stock in lieu of 65% or 100% (based on option elected by each director) of the fee payable to the Eligible Director for services rendered as a member of the Board. The number of shares issued to each Eligible Director is determined based on 75% of the market value as defined in the plan (the Company recognizes 100% of the market value of the shares issued). As of December 31, 2024, the 2003 Plan had available for issuance 204,133 shares. The Company’s 2017 Stock Option Plan, as amended (the “2017 Plan”), authorizes the grant of options to officers and employees of the Company, including any employee who is also a member of the Board, as well as to consultants of the Company. The 2017 Plan authorizes an aggregate grant of 1,740,000 NQSOs and Incentive Stock Options (“ISOs”). Consultants of the Company can only be granted NQSOs. The term of each stock option granted under the 2017 Plan shall be fixed by the Compensation and Stock Option Committee (the “Compensation Committee”), but no stock options will be exercisable more than ten years after the grant date, or in the case of an ISO granted to a 10% stockholder, five years after the grant date. The exercise price of any ISO granted under the 2017 Plan to an individual who is not a 10% stockholder at the time of the grant shall not be less than the fair market value of the shares at the time of the grant, and the exercise price of any ISO granted to a 10% stockholder shall not be less than 110% of the fair market value at the time of grant. The exercise price of any NQSOs granted under the plan shall not be less than the fair market value of the shares at the time of grant. As of December 31, 2024, the 2017 Plan had available for issuance 684,000 shares.

Each NQSO granted is for a contractual term of ten years with one-fourth vesting annually over a four-year period. The exercise price of each NQSO is $10.20 per share, which was equal to the fair market value of the Company’s Common Stock on the day preceding the grant date, in accordance with the 2003 Plan. On January 19, 2023, the Company granted ISOs to certain employees under the 2017 Plan, for the purchase of up to an aggregate 295,000 shares of the Company’s Common Stock.

As a member of the Board, each director elects to receive either 65% or 100% of the director’s fee in shares of the Company’s Common Stock. The number of shares received is calculated based on 75% of the fair market value of our Common Stock determined on the business day immediately preceding the date that the quarterly fee is due. The balance of each director’s fee, if any, is payable in cash. The Company recorded approximately $480,000 and $477,000 in years ended 2024 and 2023, respectively, in compensation expense (included in SG&A expenses) for the portion of director fees earned in the Company’s Common Stock.
