The outstanding loans payable as of the periods presented was related to our Credit and Security Agreement (Credit Agreement) with MidCap Financial Trust (MidCap) entered into on September 27, 2019 (Closing Date) and amended on March 29, 2021 (First Amendment), February 11, 2022 (Second Amendment), July 27, 2022 (Third Amendment), and on April 11, 2024 (Fourth Amendment).

The Credit Agreement provides for a $60.0 million term loan credit facility. At the Closing Date, $10.0 million was funded (Tranche 1), in May 2020, an additional $10.0 million was funded (Tranche 2), at the Second Amendment, an additional $10.0 million was funded (Tranche 3), at the Third Amendment, an additional $10.0 million was funded (Tranche 4), and in March 2023, an additional $20.0 million was funded (Tranche 5). As of June 30, 2024, the outstanding principal balance of the loan was $60.0 million, and no remaining funds are available for draw under the term loan credit facility.

The First Amendment to the Credit Agreement extended the period through which Tranche 3 was available to us. The Second Amendment to the Credit Agreement, among other things, amended the applicable funding conditions, applicable commitments and certain other terms relating to available credit facilities (Tranches 3 and 4), added additional term loan credit facility (Tranche 5), and revised certain terms related to the financial covenants.

Following the Third Amendment but prior to the Fourth Amendment to the Credit Agreement in April 2024 as discussed below, the term loans would mature on September 1, 2026, and the interest-only period was through October 1, 2024. The term loans bore interest equal to the sum of one-month Secured Overnight Financing Rate (SOFR), plus an adjustment of 0.11448%, subject to 1.50% applicable floor, plus applicable margin of 5.65%, and a final payment fee of 2.5% of principal due at maturity date.

Following the Fourth Amendment to the Credit Agreement in April 2024, the term loans mature on September 1, 2027, and the interest-only period is through October 1, 2025. The term loans bear interest equal to the sum of one-month SOFR plus an adjustment of 0.11448%, subject to a 4.00% applicable floor, plus applicable margin of 6.50%. A final payment fee of 4.25% of principal is due at maturity date. The amendment was accounted for as debt modification in accordance with the standards. The unamortized debt issuance costs are continuously being amortized as interest expense through maturity using the effective interest rate method.

We may make voluntary prepayments, in whole or in part, subject to certain prepayment premiums and additional interest payments. The Credit Agreement also contains certain provisions, such as event of default and change in control provisions, which, if triggered, would require us to make mandatory prepayments on the term loan, which are subject to certain prepayment premiums and additional interest payments. The obligations under the amended Credit Agreement are secured by a perfected security interest in all of our assets including our intellectual property.

Interest expense, including amortization of the debt discount and accretion of the final fees related to the Credit Agreement for the three months ended June 30, 2024 and 2023 was $2.0 million and $1.9 million, respectively, and for the six months ended June 30, 2024 and 2023 was $3.9 million and $3.1 million, respectively. Accrued interest of $1.8 million was included within other accrued liabilities in the condensed balance sheet as of June 30, 2024.
