A. The Parties entered into a continuation agreement dated November 18, 2023 (the “Continuation Agreement”) and a related back-to-back letter of comfort (as amended from time to time, the “Back-to-Back LoC”) in connection with the restructuring of the Company and a funding commitment (the “First Commitment”) from YA II PN, Ltd. (“Yorkville”) covering the cost forecast under the Going-Concern Budget (as such term was defined in the Continuation Agreement) of both the Parent and the Company for the period from (and including) December 1, 2023 through (and including) December 31, 2024.

B. On April 30, 2024, the Parent received a second funding commitment (the “Second Commitment” and together with the First Commitment, the “Commitments”) from Yorkville covering the cost forecast of both the Parent and Company for the period from (and including) January 1, 2025 through (and including) June 30, 2025.

C. In the context of the audit of the financial statements for the fiscal year 2023 and the intention of the Parties and Yorkville that the Commitments be used to fund the business operations of both the Parent and the Company through (and including) June 30, 2025, the Parties now wish to amend the Back-to-Back LoC by entering into this amendment (“Amendment No. 1”).

2 Amendments

2.1 The term “Going-Concern Budget” as used in the Back-to-Back LoC is hereby amended to mean the going-concern budget agreed between Yorkville, the Parent and the Company in connection with the Second Commitment, which updated budget includes the capital expenditures required by the Company through the end of the second quarter of 2025, attached as Schedule I to this Amendment No. 1, as such budget may be amended from time to time by an agreement between Yorkville, the Parent and the Company.
