payments on the revolving line of credit through November 2, 2025, at which time all outstanding indebtedness would be immediately due and payable. The outstanding principal amount of any advance accrued interest at a floating rate per annum equal to the greater of (i) three and one-half percent (3.50%) and (ii) the “prime rate” as published in The Wall Street Journal for the relevant period minus one-half percent (0.50%). Our obligations under the 2022 Revolver were secured by substantially all of our assets, excluding our intellectual property, which was subject to a negative pledge. The revolving line of credit under the 2022 Revolver was scheduled to terminate on November 2, 2025.
The 2022 Revolver also contained certain financial covenants, including a requirement that the amount of unrestricted and unencumbered cash minus advances under the 2022 Revolver was not less than the amount equal to the greater of (i) $10.0 million or (ii) nine (9) months of cash burn. The 2022 Revolver contained customary representations and warranties, as well as certain non-financial covenants, including limitations on, among other things, our ability to change the principal nature of our business, dispose of our business or property, engage in any change of control transaction, merge or consolidate with any other entity or to acquire all or substantially all the capital stock or property of another entity, incur additional indebtedness or liens, pay dividends or make other distributions on capital stock, redeem our capital stock, engage in transactions with affiliates or otherwise encumber our intellectual property, in each case, subject to customary exceptions.
As of December 31, 2023, there were no balances outstanding under the 2022 Revolver. As of December 31, 2022, the outstanding principal balance under the 2022 Revolver was $15.0 million, which was repaid in full on January 4, 2023. The interest rate applicable to borrowing under the 2022 Revolver was 7.0% as of December 31, 2022.
On March 10, 2023, the Lender, also one of our financial institutions, was closed by the California Department of Financial Protection and Innovation, which appointed the Federal Deposit Insurance Corporation, or FDIC, as receiver.
As of March 31, 2023, the Company had transferred substantially all its cash, cash equivalents and marketable securities away from the Lender and deposited the funds with new financial institutions. As a result of the transfer of the Company’s cash, cash equivalents and marketable securities, the Company was in default, of its financial covenants under the 2022 Revolver. The Company recorded a loss on extinguishment of $0.5 million in the three months ended March 31, 2023, which was included in interest expense in the condensed consolidated statements of operations.
On August 4, 2023, we entered into a Default Waiver and First Amendment to Loan and Security Agreement with the Lender, or the Amended 2022 Revolver, in which the Lender waived its rights and remedies against the Company and amended the 2022 Revolver. The Amended 2022 Revolver provides for a revolving line of credit of up to $10.0 million. The Company is permitted to make interest-only payments on the revolving line of credit through November 3, 2025, at which time all outstanding indebtedness shall be immediately due and payable. The outstanding principal amount of any advance shall accrue interest at a floating rate per annum equal to the greater of (i) four and one-half percent (4.50%) and (ii) the “prime rate” as published in The Wall Street Journal for the relevant period minus one-half percent (0.50%). The Company’s obligations under the Amended 2022 Revolver are secured by substantially all of the Company’s assets, excluding its intellectual property, which is subject to a negative pledge. The revolving line of credit under the Amended 2022 Revolver terminates on November 3, 2025. As of June 30, 2024, there were no balances outstanding under the Amended 2022 Revolver.
Pursuant to the Amended 2022 Revolver, the Lender waived filing any legal action or instituting or enforcing any rights and remedies it may have had against the Company in connection with the Company’s failing to maintain all of its operating accounts, depository accounts and excess cash with the Lender, as previously required under the 2022 Revolver. The Company recorded a credit of $0.3 million during the three months ended September 30, 2023 related to the previously recorded early termination penalties.
The Amended 2022 Revolver also contains certain financial covenants, including a requirement that the Company maintain $20.0 million on account at or through the Lender and that the amount of unrestricted and unencumbered cash minus advances under the Amended 2022 Revolver, is not less than the amount equal to the greater of (i) $10.0 million or (ii) nine (9) months of cash burn. The Amended 2022 Revolver contains customary representations and warranties, as well as certain non-financial covenants, including limitations on, among other things, the Company’s ability to change the principal nature of its business, dispose of the Company’s business or property, engage in any change of control transaction, merge or consolidate with any other entity or to acquire all or substantially all the capital stock or property of another entity, incur additional indebtedness or liens, pay dividends or make other distributions on capital stock, redeem the Company’s capital stock, engage in transactions with affiliates or otherwise encumber the Company’s intellectual property, in each case, subject to customary
