Notwithstanding anything to the contrary contained in the Merger Agreement, as amended (including Section 8.3) and Section 1 of the Amendment to Agreement and Plan of Merger, dated May 12, 2023, by and between the Parties, the Company agrees to pay the Monthly Extension Fees (as defined herein) directly into the Trust Account on behalf of Purchaser on or before the date when such payment becomes due. In addition to any remedy or relief provided to Purchaser in the Merger Agreement, if the Merger Agreement is terminated for any reason other than a breach by Purchaser, the Company agrees to pay all Expenses of Purchaser incurred after March 31, 2023, provided that in no event shall such payment exceed $3,000,000 (inclusive of any Monthly Extension Fees paid as described in the preceding sentence). In the event that the Mergers are consummated, Purchaser agrees to pay for all transaction expenses up to $10,000,000 in connection with the consummation of the Mergers and the other transactions contemplated by the Merger Agreement. “Monthly Extension Fee” means the $200,000 per month required to be paid into the Trust Account until the completion of the Mergers.

This Amendment shall be subject to, shall form a part of, and shall be governed by, the terms and conditions set forth in the Merger Agreement, as amended by this Amendment.
