 Cable Car Amendment provides that the maturity date for the Cable Car Note shall be extended to March 31, 2026, in consideration for which, we paid a fee of $90,000 to Cable Car for the extension (the “

#### Extension Fee
”), with such fee being added to the amount due and payable on such maturity date, unless the Cable Car Note is earlier converted pursuant to its terms, in which event the Extension Fee shall also be converted. No interest shall accrue or be due on the Extension Fee. Pursuant to the Cable Car Amendment, interest shall accrue on the outstanding principal balance of the Cable Car Note at an annual rate equal to 6%, with interest being calculated based on a 365-day year and the actual number of days elapsed, to the extent permitted by applicable law. Interest shall be due and payable on the maturity date for the Cable Car Note, unless the Cable Car Note is earlier converted pursuant to its terms, in which event such accrued and unpaid interest shall also be converted.

On February 26, 2025, we entered into the Credit Agreement that provides a senior secured term loan (the “

#### Lynrock Lake Term Loan
”) with Lynrock Lake. The Credit Agreement is secured by a first priority lien on substantially all our assets and provides for a term loan in the aggregate principal amount of $10,100,000 at an interest rate of 10.0% per annum, compounded quarterly. The maturity date of the Credit Agreement is March 31, 2027. Furthermore, in connection with the Lynrock Lake Term Loan, we issued to Lynrock Lake the Lynrock Lake Warrant to purchase 20,333,623 shares of our Common Stock at an exercise price of $1.20 per share. The Lynrock Lake Warrant is exercisable until February 26, 2035. Lynrock Lake may cashless exercise the Lynrock Lake Warrant. The Lynrock Lake Warrant is also subject to anti-dilution adjustments to the exercise price and the number of shares which may be purchased upon exercise of the Lynrock Lake Warrant in the event that we issue shares of Common Stock (or derivative securities) at a price that is either less than the $1.20 exercise price or the fair market value of a share of Common Stock from the immediately prior trading day.

On February 26, 2025, we used a portion of the proceeds of the Lynrock Lake Term Loan to pay Yorkville an amount equal to $3,000
