Convertible Notes

In January through May 2021, the Company issued convertible notes (the “2021 Notes”) in the aggregate principal amount of approximately $1,098,000. The 2021 Notes bear interest at a rate of 12% per annum, payable at maturity, and mature between January and May, 2022. The 2021 Notes shall automatically convert into shares of the Company’s common stock upon the closing of a financing pursuant to which the Company receives gross proceeds of at least $500,000 (a “Qualified Financing”) or upon a change of control. The 2021 Notes shall convert into such numbers of shares of the Company’s common stock equal to the conversion amount divided by the Conversion Price. “Conversion Price” means (i) in the event of a Qualified Financing, 70% of the price per share (or conversion price, as applicable) of common stock (or securities convertible into common stock, as applicable) sold in such financing or (ii) in the event of a change of control, the price per share reflected in such transaction.

The Company has accounted for the 2021 Notes as stock-settled debt and is accreting the carrying amount of the 2021 Notes to the settlement amount through maturity. As of June 30, 2021, unpaid and accrued interest of $49,000 as well as debt discount accretion expense of approximately $172,000 is included with the Convertible notes on the balance sheet.

In July through November 2020, the Company issued convertible notes (the “2020 Notes”) in the aggregate principal amount of $1,290,000. The 2020 Notes bear interest at a rate of 12% per annum, payable at maturity, and mature between July and November, 2021. The 2020 Notes shall automatically convert into shares of the Company’s common stock upon the closing of a financing pursuant to which the Company receives gross proceeds of at least $500,000 (a “Qualified Financing”) or upon a change of control. The 2020 Notes shall convert into such numbers of shares of the Company’s common stock equal to the conversion amount divided by the Conversion Price. “Conversion Price” means (i) in the event of a Qualified Financing, 70% of the price per share (or conversion price, as applicable) of common stock (or securities convertible into common stock, as applicable) sold in such financing or (ii) in the event of a change of control, the price per share reflected in such transaction.

In 2017 and 2018, the Company raised $550,000 from the issuance of twelve convertible promissory notes (the “2018 Notes”). The 2018 Notes bear interest at 10% per annum which was payable at maturity. The 2018 Notes’ principal and interest were due and payable on written demand by the majority of the 2018 Note holders on the two-year anniversary of the first 2018 Note issued. The first 2018 Note was issued on October 5, 2017 and, accordingly, all 2018 Notes would have matured on October 5, 2019. In the event the Company consummated an equity financing with an aggregate sales price of not less than $500,000, then the aggregate outstanding principal and unpaid interest would automatically convert into shares of the Company’s common stock. The per-share price of the conversion would be equal to 75% of the price per share paid by the cash purchasers of the common stock sold in the financing.

The Company accounted for the 2018 Notes as stock-settled debt and accreted the carrying amount of the 2018 Notes to the settlement amount through maturity. On July 31, 2019, all 2018 Notes principal and accrued interest were converted into 1,159,065 shares of common stock upon the consummation of a 2019 equity financing in excess of $500,000. The Company recorded, as part of the conversion of the debt, a loss on conversion of $63,000 included in other expenses.
