MidCap Term Loan

On May 26, 2022, the Company entered into the Credit and Security Agreement (the “MidCap Credit Agreement”) with MidCap Financial Trust, as agent (the “Agent”), and certain lender parties thereto. The MidCap Credit Agreement provides for up to $50.0 million in term loans (the “MidCap Term Loans”), consisting of a $40.0 million Tranche 1 (“Tranche 1”) and a $10.0 million Tranche 2 (“Tranche 2”). Upon closing, the Company borrowed $40.0 million of Tranche 1 and used a portion of the proceeds to repay borrowings under the OrbiMed Credit Facility (described below) and intends to use the remaining proceeds to fund operations and other general corporate purposes. The Company will be eligible to borrow Tranche 2 at the Company’s option upon meeting certain conditions, including, but not limited to, reaching $65.0 million of net product revenue over the preceding four quarters by fiscal year end 2023.

Pursuant to the MidCap Credit Agreement, the Company provided a first priority security interest in all existing and future acquired assets, including intellectual property, owned by the Company. The MidCap Credit Agreement contains certain covenants that limit the Company’s ability to engage in certain transactions that may be in the Company’s long-term best interests, including the incurrence of additional indebtedness, effecting certain corporate changes, making certain investments, acquisitions or dispositions and paying dividends.

The MidCap Credit Agreement also contains customary indemnification obligations and customary events of default, including, among other things, (i) non-payment, (ii) breach of warranty, (iii) non-performance of covenants and obligations, (iv) default on other indebtedness, (v) judgments, (vi) change of control, (vii) bankruptcy and insolvency, (viii) impairment of security, (ix) key permit events, (x) termination of a pension plan, (xi) regulatory matters, (xii) material adverse effect and (xiii) breach of material contracts.

In addition, the Company must maintain minimum net revenue levels tested quarterly. In the event of default under the MidCap Credit Agreement, the Company would be required to pay interest on principal and all other due and unpaid obligations at the current rate in effect plus 2%.

The MidCap Term Loans mature on May 1, 2027 and bear interest at a rate equal to 6.25% plus the greater of one-month Term SOFR (as defined in the MidCap Credit Agreement) or 1.0%. The Company is required to make 36 monthly interest payments beginning on June 1, 2022 (the “Interest-Only Period”). If the Company is in covenant compliance at the end of the Interest-Only Period, the Company will have the option to extend the Interest-Only Period by 12 months to 48 monthly interest payments, followed by 12 months of straight-line amortization, with the entire principal payment due at maturity. If the Company is not in covenant compliance at the end of the Interest-Only Period, the Company is required to make 24 months of straight-line amortization payments, with the entire principal amount due at maturity.

Subject to certain limitations, the MidCap Term Loans have a prepayment fee equal to 3.0% of the prepaid principal amount for the first year following the closing date of the MidCap Term Loans, 2.0% of the prepaid principal amount for

the second year following the closing date and 1.0% of the prepaid principal amount for the third year following the closing date and thereafter. The Company is also required to pay an exit fee at the time of maturity or prepayment event equal to 5% of all principal borrowings (the “End of Term Charge”) (or in the event of a prepayment event, the amount of principal being prepaid). Interest expense associated with the MidCap Credit Facility recorded for the year ended December 31, 2022 was $2.6 million, of which $0.4 million was related to the amortization of debt issuance costs.

OrbiMed Term Loan (Related Party)

In November 2018, the Company entered into the OrbiMed Credit Facility with OrbiMed, a related party as the lender is affiliated with a stockholder of the Company, which consisted of up to $35.0 million in term loans (the “OrbiMed Term Loans”). The OrbiMed Term Loans consisted of two tranches, a $30.0 million Tranche 1 (“First Tranche”) and a $5.0 million Tranche 2 (“Second Tranche”). In November 2018, the Company borrowed $30.0 million of the First Tranche. The Company elected not to borrow the Second Tranche prior to its expiration on December 31, 2019. On May 26, 2022, the Company entered into the MidCap Credit Agreement and upon closing used a portion of the proceeds to repay all borrowings under the OrbiMed Credit Facility.

The OrbiMed Term Loan bore interest at a rate equal to 7.75% plus the greater of one-month LIBOR or 2.0% until the aggregate principal, interest and End of Term Charge of $3.0 million were paid with part of the proceeds received from the MidCap Credit Agreement. As a result of these payments, a $1.2 million loss on extinguishment was recorded during the year ended December 31, 2022. Interest expense associated with the OrbiMed Credit Facility recorded for the year ended December 31, 2022, was $1.5 million, of which $0.3 million was related to the amortization of debt issuance costs. Interest expense associated with the OrbiMed Credit Facility recorded for the year ended December 31, 2021, was $3.6 million, of which $0.7 million was related to the amortization of debt issuance costs.
