Stock options description						On July 15, 2020, as amended on August 12, 2020, in connection with the employment agreement entered into with Eric J. Forman, Mr. Forman was granted options for 58,333 shares of the Company’s common stock. The options can be exercised on a cashless basis. The options have a term of five years and an exercise price of $7.14 per share, which was equal to the closing price of the Company’s common stock on the grant date. The options vested as to 25% on August 12, 2020, and will vest 25% on each of the first, second and third anniversaries of the grant date. The fair value of these stock options, as calculated pursuant to the Black-Scholes option-pricing model, was determined to be $400,855 ($6.8718 per share), of which $100,214 was attributable to the stock options fully-vested on August 12, 2020 and was therefore charged to operations on that date. The remaining unvested portion of the fair value of the stock options will be charged to operations ratably from August 12, 2020 through August 12, 2023. During the three months and six months ended June 30, 2021, the Company recorded charges to general and administrative costs in the consolidated statement of operations of $24,985 and $49,695, respectively, with respect to these stock options.
