7. Oxford Finance Loan Agreement

On February 12, 2020, the Company entered into a Loan and Security Agreement (the “Loan Agreement”) with Oxford Finance LLC (the “Lender”). Pursuant to the Loan Agreement, a term loan of up to an aggregate principal amount of $60.0 million is available to the Company. A $20.0 million term loan was funded on February 12, 2020, and two additional term loan advances of $20.0 million each remain available under the Loan Agreement, subject to certain terms and conditions, including the achievement of certain milestones.

The term loan bears interest at an annual rate equal to the greater of (i) 7.75% and (ii) the sum of 5.98% and the greater of (A) one-month LIBOR or (B) 1.77%. The Loan Agreement provides for interest-only payments until March 1, 2023, and repayment of the aggregate outstanding principal balance of the term loan in monthly installments starting on March 1, 2023 and continuing through February 1, 2025 (the “Maturity Date”). The Company paid a facility fee of $0.1 million upon closing, and in addition will pay a facility fee of $75,000 upon closing of the second loan tranche and a $50,000 facility fee upon the closing of the third loan tranche. The Company will be required to make a final payment fee of 5.00% of the amount of the term loan drawn payable on the earlier of (i) the prepayment of the term loan or (ii) the Maturity Date. At the Company’s option, the Company may elect to prepay the loans subject to a prepayment fee equal to the following percentage of the principal amount being prepaid: 2% if an advance is prepaid during the first 12 months following the applicable advance date, 1% if an advance is prepaid after 12 months but prior to 24 months following the applicable advance date, and 0.5% if an advance is prepaid any time after 24 months following the applicable advance date but prior to the Maturity Date.

In connection with the Loan Agreement, the Company granted the Lender a security interest in all of the Company’s personal property now owned or hereafter acquired, excluding intellectual property (but including the right to payments and proceeds of intellectual property), and a negative pledge on intellectual property. The Loan Agreement also contains certain events of default, representations, warranties and non-financial covenants of the Company.

In addition, under the Loan Agreement, the Company issued the Lender warrants to purchase 27,548 shares of the Company’s common stock at an exercise price per share of $7.26 (the “Oxford Warrants”). The Oxford Warrants will be exercisable for five years from the date of issuance.

The Oxford Warrants are classified as a component of permanent equity because they are freestanding financial instruments that are legally detachable and separately exercisable from the shares of common stock with which they were issued, are immediately exercisable, do not embody an obligation for the Company to repurchase its shares, and permit the holders to receive a fixed number of shares of common stock upon exercise. In addition, the Oxford Warrants do not provide any guarantee of value or return. The Company valued the Oxford Warrants at issuance using the Black-Scholes option pricing model and determined the fair value of the Oxford Warrants to be $0.1 million. The key inputs to the valuation model included an average volatility of 75.43% and an expected term of 5.0 years.

The Company has the following minimum aggregate future loan payments as of September 30, 2020 (in thousands):

For the three and nine months ended September 30, 2020, interest expense related to the Loan Agreement was approximately $0.5 million and $1.2 million, respectively. The total carrying value of debt is classified as long-term on the Company’s condensed consolidated balance sheets as of September 30, 2020.
