The 2023 Note is due and payable on January 27, 2026, the third anniversary of the date on which the 2023 Note was funded (the “Closing Date”), and accrues interest at a rate of 10% per year from the Closing Date, payable on a quarterly basis, until the 2023 Note is repaid in full.

The relative fair value of the warrant was $0.4 million and was recorded as a discount to the note payable in accordance with FASB ASC 835-30-25, Recognition, and is being accreted over the term of the note payable for financial statement purposes.
