    <ffd:OfferingNote contextRef="c_offering_4" id="fee_042">As estimated solely for the purpose of calculating the amount of the registration fee pursuant to Rule 457(g) under the Securities Act, the proposed maximum offering price of the Class A Ordinary Shares issuable upon exercise of the Warrants included in the Units that are proposed to be sold in the offering is $6,952,000, as Warrant is exercisable at the exercise price equal to $0.869 per share and the maximum number of Class A Ordinary Shares upon cash exercise is 8,000,000.&lt;br/&gt;&lt;br/&gt;However, a holder of the Warrants may also effect the zero exercise price option at any time while the Warrants are outstanding. The aggregate number of Class A Ordinary Shares issuable in such zero exercise price option pursuant to any given notice of exercise electing to effect a zero exercise price option under a Warrant shall be up to 16,000,000. We do not expect to receive any proceeds from the zero exercise price option of the Warrants because it is highly unlikely that a holder of the Warrants would elect to exercise the Warrants by paying cash or via cashless exercise in lieu of the zero exercise price option. The maximum number of Class A Ordinary Shares issuable under all Warrants (including the zero exercise price option) shall not exceed 16,000,000. As such, holders of the Warrants may elect to be issued up to 16,000,000 Class A Ordinary Shares upon the zero exercise price option.</ffd:OfferingNote>
