In accordance with the Support Agreement, the Governance Conditions include the following: - the election of a designated director named in the Support Agreement as a member of the Board to be voted upon in an extraordinary general meeting of the shareholders of the Issuer to be called no later than February 4, 2025 and held 21 days thereafter (the "Extraordinary General Meeting"); - the appointment of a designated observer named in the Support Agreement to the Board to be approved by the Board in a meeting of the Board to be called on the date of the Extraordinary General Meeting and held within two days thereafter; - resolutions at the Extraordinary General Meeting to (a) approve an amendment to the Bylaws to provide for the additional designated director and the board observer, and (b) approve a management incentive plan (the form of the amended and restated Bylaws is attached as a schedule to the Support Agreement); - resolutions at the next annual general meeting of shareholders of the Issuer (that is scheduled to take place on April 30, 2025) to (a) reduce the size of the Board from thirteen members to nine members (the "Board Size Reduction") and (b) nominate and elect the designated board observer to serve as a member of the Board (whereupon both designated directors named in the Support Agreement shall be elected directors of the Issuer); - resolutions for approval by the holders of the Common Shares and the holders of the Preferred Shares, respectively, at extraordinary meetings of shareholders to amend the Bylaws to provide for (a) the automatic conversion of the Preferred Shares and the Common Shares into a single class of voting shares of the Issuer on the Conversion Date (as defined in paragraph 2 of article 55 of the form of amended and restated Bylaws attached as a schedule to the Support Agreement) and (b) a provision to determine the ratio in which the Preferred Shares shall be converted to Common Shares pursuant to the provisions of article 55 of the form of amended and restated Bylaws; and - prior to the election of a new Board following the implementation of a single-class structure contemplated by article 55 of the form of amended and restated Bylaws, and so long as one or both of the Appointed Directors referred to in the Governance Conditions are member of the Board, the approval of at least one of the Appointed Directors shall be required at any meeting of the Board involving the approval of any Reserved Matter (as defined in the Support Agreement) or the submission of any such Reserved Matter to the vote of the shareholders of the Issuer. As further described in the form of amended and restated Bylaws referred to above, the Conversion Date is the earliest to occur of (a) the effective date of the consummation of a Business Combination (as defined in paragraph 2 of article 55 of the form of amended and restated Bylaws attached as a schedule to the Support Agreement), (b) May 1, 2026 (subject to extension in certain circumstances specified therein), and (c) September 15, 2026.
