Common Stock

On March 20, 2020, we sold an aggregate of 3,931,428 shares of our common stock to the five members of our Board of
Directors in a private placement exempt from registration under Section 4(a)(2) and Rule 506(b) of Regulation D under the
Securities Act of 1933, as amended. We received proceeds of $688,000 in this offering. On March 27, 2020, we closed on the
first tranche of a registered direct offering in which we sold 3,115,001 shares of our common stock for gross proceeds of
$545,125. On April 2, 2020, we closed on a second tranche of the registered direct offering in which we sold 1,400,285 shares
of our common stock for gross proceeds of $245,050. On June 8, 2020, we raised $5.5 million in gross proceeds, before expenses, through the sale of our common stock and on July 27, 2020, we raised $10.75 million in gross proceeds, before expenses, through sales of our common stock. On January 19, 2021, we raised $8 million in gross proceeds, before expenses, through the sale of our common stock, and on January 22, 2021, we raised $6.25 million in gross proceeds, before expenses, through sales of our common stock.

In 2020, our convertible promissory notes were converted into $3 million of common stock. See Note 8 - Convertible Promissory Note for details.

Warrants

On September 17, 2021, we signed an agreement with a marketing platform and consulting company to provide referral and support services to us for a period of five years (see Note 11 - Commitments). As part of that agreement, we granted a warrant exercisable into 300,000 shares of our common stock, which vests in two tranches when certain performance metrics are achieved. The warrant was valued using the Black Scholes option pricing model at a total of $149,551 based on a seven-year term, an implied volatility of 100%, a risk-free equivalent yield of 1.17%, and a stock price of $0.71. The warrant is classified as equity and will be expensed on a ratable basis over the vesting period of each tranche. For the twelve months ended December 31, 2021, we recognized approximately $20 thousand in expense and $130 thousand is unrealized.
Earnings per Share

During the 2021 and 2020, we generated a net loss from continuing operations and as a result, all of our shares are anti-dilutive.

Treasury Stock

On July 14, 2020, our Board of Directors authorized the cancellation of the 376,527 shares of treasury stock.
