Promissory Notes In a series of transactions during 2010 and 2011 two of the Company’s founders provided $0.2 million to the Company to fund general corporate purposes in exchange for promissory notes. The notes accrue interest annually at a simple interest rate of 5% with no set maturity date. During the year ended December 31, 2022, the Company borrowed $0.3 million from two of its founders at zero interest rate to finance its short -termoperations, from which $0.2 million was repaid in the same period. During the year ended December 31, 2023, the Company borrowed short -termpromissory notes of $0.3 million from an existing investor and additional $0.1 million from an unrelated party repayable on demand at any time after December 31, 2023, with annual interest rate of 12%. The Company made a repayment of $0.2 million from the outstanding balance of the loan (See Note 11, Related Party Transactions).
