Equity Purchase Agreement

On December 28, 2022, the Company entered into a purchase agreement (the “Equity Purchase Agreement”) with Alumni Capital LP, a Delaware limited partnership (“Alumni Capital”), pursuant to which the Company agreed to sell, and Alumni Capital agreed to purchase, upon request of the Company in one or more transactions, a number of shares of the Company’s common stock providing aggregate gross proceeds to the Company of up to $3,000,000 (subject to the right, but not the obligation, of the Company to increase such amount up to $10,000,000 pursuant to the terms of the Equity Purchase Agreement) (the “Maximum Investment Amount”). The Equity Purchase Agreement expires upon the earlier of the aggregate gross proceeds from the sale of shares of common stock meeting the Maximum Investment Amount or December 28, 2024.

Among other limitations, unless otherwise agreed upon by Alumni Capital, each individual sale of shares of common stock will be limited to a sale of shares of common stock of up to $500,000 (subject to the right of the Company and Alumni Capital to mutually agree to increase such figure to $1,000,000) and further limited to no more than the number of shares of common stock that would result in the direct or indirect beneficial ownership by Alumni Capital of more than 9.99% of the then-outstanding shares of common stock. Alumni Capital will purchase the shares of common stock under the Equity Purchase Agreement at the lowest traded price of the common stock during the three (3) business days immediately prior to the date of purchase of the shares of common stock multiplied by 95%.

Upon execution of the Equity Purchase Agreement, the Company issued 7,335 shares of common stock to Alumni Capital. The Company will issue to Alumni Capital, on December 28, 2023, shares of common stock in an amount equal to one-half of one percent (0.5%) of the Investment Amount (as defined in the Equity Purchase Agreement) divided by the closing price of the common stock on the third business day prior to the date of issuance and delivery of such shares of common stock. In addition, the Company will issue to Alumni Capital, on the date of expiration of the Equity Purchase Agreement, shares of common stock in an amount equal to one-half of one percent (0.5%) of the Investment Amount divided by the closing price of the common stock on the third business day prior to the date of issuance and delivery of such shares of common stock. If the Company elects to increase the Maximum Investment Amount, it shall issue to Alumni Capital Increase Commitment Shares (as defined in the Equity Purchase Agreement) (based on each increase of Investment Amount) within five (5) business days of the Company’s written notice of such election. The Company recorded the commitment shares issued and future commitment share obligation as additional paid-in capital during the three months ended December 31, 2022.

As of June 30, 2023, the Company has not sold any shares of common stock under the Equity Purchase Agreement.
