9. CONVERTIBLE DEBT

On December 22, 2021, we entered into a $25.0 million contingent convertible debt agreement, or Original Debt Agreement, with SVB, and SVB Innovation Credit Fund VIII, L.P., or, together with SVB, the Lenders. As part of the Original Debt Agreement, the Lenders funded $15.0 million in the form of convertible indebtedness, or Convertible Debt, at closing. On April 26, 2022, we entered into (i) a loan and security agreement, or Loan Agreement, with SVB for the remaining $10.0 million remaining in the Original Debt Agreement, pursuant to which SVB provided a commitment to extend term loans having an aggregate original principal amount of up to $10.0 million, or Term Loans, and (ii) a first amendment to the Original Debt Agreement, or the Amendment, and as amended by the Amendment, the Debt Agreement.

Under the terms of the Debt Agreement, the Convertible Debt matures on December 22, 2023 and may be extended to December 22, 2024 upon our written request and SVB’s approval on or prior to December 22, 2023. The Convertible Debt will accrue interest at the aggregate of (a) a floating rate per annum equal to the greater of (i) 2.25% and (ii) the prime rate minus 1.0%, which interest is payable in cash monthly in arrears, and (b) 7.0% per annum, which interest shall compound monthly.

Subject to certain terms and conditions, the Lenders may convert all or any part of the outstanding Convertible Debt and accrued and unpaid interest at any time prior to maturity into shares of our common stock at a conversion price equal to $9.34 per share, subject to customary anti-dilution adjustments. Additionally, all outstanding Convertible Debt, including accrued and unpaid interest, will mandatorily convert into shares of our common stock, at the conversion price, on such date, if any, when the closing price per share of our common stock has been equal to or greater than $24.00 for thirty consecutive trading days prior to such date).

We have the right, or Call Right, at any time to repay and retire all (but not less than all) of the outstanding Convertible Debt and accrued and unpaid interest, if any, prior to its conversion by payment of a premium determined based on the date of such repayment equal to:

in either case together with all accrued and unpaid interest on the principal balance of the Convertible Debt. If the Call Right is exercised by us, the Lenders will retain certain lookback rights in the event we enter into an agreement to be acquired in the twelve months following the exercise of the Call Right. We agreed to grant the Lenders a security interest in virtually all of our assets, including our patents and other intellectual property as security for our obligations under the Debt Agreement. Further, the Debt Agreement contains customary affirmative and restrictive covenants, including covenants regarding the incurrence of additional indebtedness or liens, investments, transactions with affiliates, delivery of financial statements, payment of taxes, maintenance of insurance, dispositions of property, mergers or acquisitions, and the requirement we keep substantially all of our cash and investments with SVB, among other customary covenants.

Subject to the terms and conditions of the Loan Agreement, we may borrow term loans under the Loan Agreement until April 30, 2023.  Amounts borrowed under the Loan Agreement will incur interest at a floating rate equal to the greater of 3.50% and the Wall Street Journal prime rate, and will be subject to interest only payments through April 30, 2024.  Commencing on May 1, 2024, the outstanding loans under the Loan Agreement will be repaid in 24 consecutive equal monthly installments of principal plus accrued and unpaid interest.  The Term Loans mature on April 1, 2026.  Upon the earliest to occur of the maturity date, repayment of the Term Loans in full, acceleration of the loans or termination of the Loan Agreement, we will be required to pay a final payment equal to the aggregate principal amount of the Term Loan advances extended by SVB multiplied by 6.0%. Our obligations under the Loan Agreement are secured by substantially all of our assets, other than our intellectual property.

Upon and after borrowing under the Loan Agreement, we must comply with certain financial covenants as set forth in the Loan Agreement and the Amendment, including a minimum liquidity ratio of at least 1.25 to 1.00, or at our election after receiving at least $30 million in net cash proceeds from the issuance and sale of equity securities, a minimum market capitalization of at least $250 million.  The Loan Agreement also contains customary affirmative and restrictive covenants, including covenants regarding the incurrence of additional indebtedness or liens, investments, transactions with affiliates, delivery of financial statements, payment of taxes, maintenance of insurance, dispositions of property, mergers or acquisitions, among other customary covenants.  We are also restricted from paying dividends or making other distributions or payments on its capital stock, subject to limited exceptions. The Loan Agreement includes customary representations and warranties, events of default and termination provisions. In addition to the financial covenants described above, the Amendment makes certain other changes to the Original Debt Agreement related to our entry into the Loan Agreement. As of December 31, 2022 no amounts had been drawn on the Term Loans.

Under ASU 2020-06, the embedded conversion feature was not required to be bifurcated and recognized separately, as a result the convertible debt including the conversion feature has been recognized as a single unit of debt. The debt issuance costs have been recognized against the single unit of debt and will be amortized into interest expense over the term of the loan.

As of December 31, 2022, the Convertible Debt balance was comprised of the following:
