(b) The Registrant previously paid registration fees to register 14,075,000 IQM Warrants, including the Private Placement Warrants and Public Warrants, on the Prior Registration Statement and, consistent with the response to Question 240.06 of the Securities Act Rules Compliance and Disclosure Interpretations and pursuant to Rule 457(g) of the Securities Act, the registration fee with respect to such IQM Warrants was allocated to the IQM Shares issuable upon exercise of such IQM Warrants, and those IQM Shares were included in the total registration fee paid in connection with the Prior Registration Statement. Such offering of 14,075,000 IQM Warrants, including the Private Placement Warrants and Public Warrants, and the deemed offering of the shares underlying such warrants correspond to $24,880.10 of the total $57,820.23 fees calculated and paid in connection with the Prior Registration Statement. The Registrant is therefore claiming $22,150.75 as a fee offset related to the 3,905,981 Private Placement Warrants and the 8,624,989 Public Warrants, and the deemed offering of the IQM Shares, including the IQM Shares represented by IQM ADSs, underlying such warrants. None of the issued and outstanding Private Placement Warrants and Public Warrants that were registered on the Prior Registration Statement have been exercised and, consequently, none of the IQM Shares underlying such warrants have been issued or sold under the Prior Registration Statement. The Registrant now intends to register, among others, the issuance and sale of the IQM Shares, including the IQM Shares represented by IQM ADSs, in connection with the exercise of any of the issued and outstanding Private Placement Warrants and Public Warrants under this Registration Statement on Form F-1.</ffd:TermntnCmpltnWdrwl>
