In September 2016, in connection with the United States government's foreign national investor program, commonly known as the EB-5 Program, the Company entered into the EB-5 Loan Agreement which provided for cumulative borrowings of up to $10.0 million from EB-5 Life Sciences as the lender. Pursuant to the EB-5 Loan Agreement, borrowings were made in $0.5 million increments with a fixed interest rate of 4.0% per annum (the "Original Offering"). The borrowings pursuant to the Original Offering are secured by substantially all of the Company's assets, with the exception of any patents, patent applications, pending patents, patent licenses, patent sublicenses, trademarks, and other intellectual property rights held by the Company.

Under the terms and conditions of the Original Offering, the Company borrowed $1.0 million during 2016, $0.5 million during 2020, $0.5 million in September 2022, and an additional $0.5 million in May 2023. Issuance costs were recognized as a reduction to the loan balance and are amortized to interest expense over the term of each borrowing. Pursuant to the Original Offering, each outstanding borrowing, including accrued interest, becomes due upon the seventh anniversary of its disbursement date, subject to certain extension provisions. In January 2024, the Company entered into an agreement to extended the current portion of borrowings owed under the EB-5 Loan Agreement to March 2025. Once repaid, amounts cannot be re-drawn.

The March 2022 EB-5 Reform and Integrity Act of 2022 (the "RIA") enacted changes to the EB-5 Program, including but not limited to: raising the minimum investment amount for a targeted employment area (the "TEA") from its previous level of $0.5 million to its new level of $0.8 million, as well as modifying the process for the creation of TEAs. Under the previous regime, the state in which the TEA would be located could send a letter in support of efforts to designate a TEA. Under the current regime, only United States Citizenship and Immigration Services can designate TEAs.

In connection with the aforementioned changes to the EB-5 Program, the Original Offering was amended in May 2023 (the "Amended Offering"). Pursuant to the terms and conditions of the Amended Offering, EB-5 Life Sciences now provides for cumulative borrowings of up to $20.0 million. Future borrowings can be made in increments of $0.8 million with a fixed interest rate of 4.0% per annum. Each future borrowing pursuant to the Amended Offering, including accrued interest, will become due upon the seventh anniversary of its disbursement date. The Company has not made any borrowings pursuant to the Amended Offering as of December 31, 2024.

In November 2024, the Company entered into a debt financing transaction with Avenue Capital for net proceeds of $29.2 million. The loan has a maturity date of November 1, 2028, of which the first 24 months are interest only, and bears interest at a variable rate per annum equal to the greater of the Prime Rate plus 4.25% or 12.25%. Additionally, the Lender has the right to convert an aggregate amount of up to $6.0 million of the outstanding principal amount into shares of Common Stock at a conversion price per share equal to a 80% of the trading price on the date of conversion, which shall be at Lenders' option. In the event the Company elects to prepay the Term Loans in full, Lenders shall have 10 days to elect to exercise its conversion right prior to such prepayment. All conversion rights shall terminate on Term Loans payoff. Notwithstanding the foregoing, the aggregate amount of Common Stock issued pursuant to the “Conversion Right” and the “Equity Grant” shall not exceed a number of shares equal to 19.9% of the Company’s outstanding Common Stock. The agreement is collateralized by all of the Company’s assets in which the Agent is granted senior secured lien. The Company also granted the Lenders a negative pledge on the Company’s intellectual property. In connection with the debt financing transaction, the Company entered into a Subscription Agreement with Avenue Capital, pursuant to which the Company issued 1,056,338 shares of Common Stock to Avenue Capital with an issue date of November 6, 2024.
