|
On July 25, 2022, the Company and Richard E. Uihlein (the “Lender”) entered into a Line of Credit Letter Agreement (the “Credit Agreement”), pursuant
to which the Lender shall provide the Company a line of credit of up to $60.0 million (the “Line of Credit”) to finance the Company’s
working capital needs. The Company may draw upon the Line of Credit through July 31, 2024.
Each advance made pursuant to the Credit Agreement shall be evidenced by an unsecured, convertible promissory note (individually, a “Promissory
Note,” and collectively, the “Promissory Notes”), and bear interest at the Applicable Federal Rate for short term loans, plus two (2%)
percent. Principal and interest on the Promissory Notes are due on or before January 31, 2026. Only with the consent of the Lender,
may the Promissory Notes be prepaid, in whole or in part, at any time without premium or penalty, but with interest on the amount or amounts prepaid.
At the election of Lender, the principal and accrued interest on Promissory Note(s) may be converted into the number of shares of the Company’s
Common Stock equal to the amount of principal and accrued interest on such Promissory Note divided by the price equal to the closing price of the Common Stock on the date of such Promissory Note, but in no event less than $3.00 per share.
In connection with the Credit Agreement, the Company agreed to issue the Lender warrants to purchase up to an aggregate of 1,700,000 shares of the Company’s common stock, par value $0.001 per share (collectively, the “Warrants”). Upon execution of the Credit Agreement, the Company issued the Lender a Warrant to purchase up to 500,000 shares of Company’s Common Stock at an exercise price of $5.00
per share, which Warrant is exercisable upon issuance. Further, pursuant to the Credit Agreement, the Company shall issue to the Lender additional Warrants to purchase up to the remaining 1,200,000 shares of the Company’s common stock, ratably, upon borrowings under the Credit Agreement, with exercise prices equal to 150% of the closing price of the Company’s common Stock on the date of the Promissory Note evidencing such draw, but in no event more than $10.00 per share nor less than $3.00 per share. The Warrants
expire on July 31, 2029.
The fair value of the 500,000
warrants vested at closing on July 25, 2022 was $738,000 at the date of issuance based on the following assumptions: an expected life
of 7 years, volatility of 92%,
risk free interest rate of 3.19% and zero
dividends. The fair value of the vested warrants was recorded in other assets (non-current) as a deferred financing cost and will be amortized on a straight-line basis from July 25, 2022 through January 31, 2026. Amortization for the years ended
December 31, 2024 and 2023 of $210,000 and $209,000, respectively, was recorded as interest expense.

materially different than the effective interest method, from December 19, 2022 through January 31, 2026. Amortization for the years ended December 31, 2024 and 2023 of $52,000 and $51,000, respectively, was recorded as interest
