This Statement is filed on behalf of each of the following persons (collectively, the “Reporting Persons”):

This Statement on Schedule 13G relates to 700,000 shares of Common Stock (as defined herein) that K2HV Equity holds directly and 4,624,144 shares of Common Stock that K2HV Equity has the right to acquire within 60 days upon conversion of up to $50,000,000 of convertible term loans that the Reporting Persons, through a lender affiliate, agreed to extend to the Issuer (the “Convertible Term Loans”), of which $30,000,000 is fully funded as of the date of this Schedule 13G (the “First Tranche”) and an additional uncommitted $20,000,000 may be funded at the discretion of the Reporting Persons (the “Third Tranche”). Pursuant to the terms of the loan and security agreement governing the Convertible Term Loans (the “Loan and Security Agreement”), the Reporting Persons may elect at any time following the September 9, 2022 closing date and prior to the repayment in full of the Convertible Term Loans to convert any portion of the principal amount of the Convertible Term Loans then outstanding into shares of Common Stock, at the then-applicable conversion price and subject to the Blockers (as defined herein).  The current conversion price of the fully-funded First Tranche is $4.785 per share (the conversion price for the Third Tranche will be a price equal to 140% of the Lowest Trailing Three-Day VWAP (as defined in the Loan and Security Agreement) during the 30 day period immediately preceding funding of the Third Tranche).  Pursuant to the terms of the Loan and Security Agreement, the Reporting Persons may not convert any portion of the Convertible Term Loans into shares of Common Stock to the extent that, upon conversion, the beneficial ownership of the Reporting Persons (including any affiliates and Section 13(d) “group” members) would exceed 9.985% of the total number of shares of Common Stock outstanding (the “9.985% Cap”) or 19.99% of the total number of shares of Common Stock outstanding (the “19.99% Cap” and, together with the 9.985% Cap, the “Blockers”).  The Reporting Persons may waive the 9.985% Cap upon 61 days’ prior written notice to the Issuer, but may not waive the 19.99% Cap.

K2HV Equity is an investment vehicle for holding equity securities and may be deemed to directly beneficially own the shares of Common Stock that it holds directly and has the right to acquire within 60 days upon conversion of the Convertible Term Loans.  Mr. Shah and Mr. Arora serve as the managing members of K2HV Equity and, in such capacities, may be deemed to indirectly beneficially own the shares of Common Stock that K2HV Equity holds directly and has the right to acquire within 60 days upon conversion of the Convertible Term Loans.

The business address of each of the Reporting Persons is: 855 Boylston Street, 10th Floor, Boston, MA 02116.
