NOTE 6 — Stock-Based Compensation Plan

Stock-Based Compensation Program

The Company has one share-based compensation plan in effect for the two years presented: the 2004 Equity Incentive Plan (the “2004 Plan”). The plan allows for the grant of incentive stock options, non-statutory stock options, restricted stock, stock appreciation rights, and performance awards to employees, directors, and consultants. Stock options are granted at an exercise price per share equal to the fair market value per share of common stock on the date of grant. Restricted stocks are granted at zero cost. Vesting and exercise provisions are determined by the Board of Directors, with a maximum term of ten years. The 2004 Plan is set to terminate on April 23, 2034.

The 2004 Plan allows for an annual increase in the number of shares authorized under the plan to be added on the first day of each fiscal year equal to the least amount of 400,000 shares, 4% of the outstanding shares on that date, or an amount as determined by the Board of Directors. On January 1, 2026 and 2025, a total of 319,078 and 304,225 additional shares, respectively, became available for grant from the 2004 Plan.

As of December 31, 2025, the remaining unamortized stock-based compensation expense was $1,139,147 and is expected to be amortized over a weighted average period of 2.4 years.

Stock Options – Stock option awards have an exercise price equal to the closing price on the date of grant, expire ten years from the date of grant and vest over a four-year period at 25% per year. The Company calculates the value of each stock option grant, estimated on the date of grant, using binomial lattice option pricing model.

On October 1, 2025, the Company granted 25,000 stock options at a closing market price of $1.02.

On June 25, 2024, the Company completed a one-time tender offer to exchange 613,936 stock options granted under its 2004 Equity Incentive Plan for current employees, executive officers, and directors. All surrendered options were cancelled as of the Exchange Offer’s expiration on June 25, 2024. The Company granted new options to purchase an aggregate of 613,936 shares of common stock pursuant to the terms of the Exchange Offer and 2004 Equity Incentive Plan. These new options were priced at the closing market price of $1.1197 on June 25, 2024, with monthly vesting over 4 years and a 10-year expiration date of June 25, 2034. The Company’s stockholders approved the stock option exchange program at the 2024 annual meeting on May 15, 2024. The Company accounted for the exchange as a modification of the options and calculated the incremental expense to be $187,117, which will amortized over the estimated life of the new options. Additionally, on June 26, 2024, the Company granted 75,000 stock options at a closing market price of $1.08.

The weighted-average estimated fair value of stock options granted in 2025 was $0.581, determined using a binomial lattice valuation model with the following weighted-average assumptions:

The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant; the dividend yield is calculated as the ratio of dividends paid per share of common stock to the stock price on the date of grant; the expected life is based on historical and expected exercise behavior; and volatility is based on the historical volatility of the Company’s stock price over the expected life of the option.
