In the event that it is reasonably determined by the Company and SPAC that it is reasonably likely that the Merger will not be consummated by March 31, 2025, SPAC shall (a) use its reasonable best efforts to cause the SPAC Board to approve such amendment to the SPAC Charter to provide that the date by which SPAC must consummate a Business Combination in accordance with the SPAC Charter is extended from March 31, 2025 to June 22, 2025 (such date by which SPAC must consummate a Business Combination in accordance with the SPAC Charter, as amended, and as may be extended in accordance with the provisions of this Section 7.6, the “Business Combination Deadline” and such proposal, the “Extension Proposal”) and resolve to recommend that the SPAC Shareholders approve such Extension Proposal by special resolution (the “Extension Recommendation”), and not change or modify or propose to change or modify the Extension Recommendation, and (b) prepare and file with the SEC a proxy statement (such proxy statement, together with any amendments or supplements thereto, the “Extension Proxy Statement”) for the purpose of soliciting proxies from SPAC Shareholders for the Extension Proposal, which shall include, among other things, (x) a description and introduction of the Company, and (y) a statement that this Agreement and other Transaction Documents have been entered into.
