Credit Agreements

Blackstone Credit Agreement

In August 2021, the Company entered into the Blackstone Credit Agreement that provides for (i) a senior secured term loan facility in an aggregate original principal amount of $200,000 (the “Initial Term Loan”) and (ii) a senior secured

delayed draw term loan facility in an aggregate principal amount up to $100,000 (the “DDTL” and, together with the Initial Term Loan, the “Loans”). The DDTL will be available to draw down through August 9, 2022.

The repayment schedule for the Initial Term Loan consists of quarterly $500 principal payments commencing on December 31, 2021 and increasing to quarterly $5,000 principal payments beginning on March 31, 2024, with a $145,500 payment due on the maturity date of August 9, 2026 (“Maturity Date”). Interest is payable quarterly, which commenced on November 9, 2021 and continuing through the Maturity Date. The Initial Loan bears interest at a per annum rate equal to LIBOR, subject to a 1.00% floor, plus 6.50%.

The net cash received related to the Initial Term Loan as a result of the transaction, less debt issuance costs of $8,151, was $191,849. The debt issuance costs related to the Initial Term Loan will be amortized as additional interest expense over the five-year loan term of the Blackstone Credit Agreement. In addition, the Company paid $1,000 in debt issuance costs relating the DDTL, which are recorded in other current assets within the consolidated balance sheet. The fair value of the Initial Term Loan as of December 31, 2021 was $185,389.

OrbiMed Credit Agreement

In January 2020, the Company entered into a credit agreement with OrbiMed for an aggregate amount of $200,000 (the “OrbiMed Loan”), with a maturity date of January 2026. Borrowings under the OrbiMed Loan are collateralized by all of the Company’s assets, excluding the intellectual property licensed through the License Agreement. The OrbiMed Loan bears an interest rate equal to the sum of (i) the greater of (a) 1-month LIBOR or (b) 2.00% per annum, plus (ii) 11.00% per annum, paid in cash monthly in arrears on the last day of each month starting in January 2020. At the time of prepayment or repayment of all or any portion of the principal of the OrbiMed Loan, the Company is required to pay an exit fee of 7.0% of the principal amount of the OrbiMed Loan prepaid, repaid, or required to be prepaid or repaid. The Company recorded the exit fee as a liability and debt discount at the origination of the term loan.

In connection with the OrbiMed Loan, the Company extinguished its $200,000 multi-draw loan agreement with CRG Servicing LLC (the “CRG Loan”), which required a payoff amount of $120,893 consisting of principal repayment, interest, and exit fees. In connection with extinguishment of the CRG Loan, the Company recognized a loss on extinguishment of $22,639 within the Company’s consolidated statements of operations for the nine months ended September 30, 2020.

In connection with the Blackstone Credit Agreement, the Company extinguished the OrbiMed Loan, which required a payoff amount of $222,666 consisting of principal repayment, interest, exit fees and a prepayment premium. The Company recognized a loss on extinguishment of $26,146 relating to the OrbiMed Loan within the Company’s consolidated statements of operation for the year ended December 31, 2021.
