Estimated solely for purposes of calculating the registration fee pursuant to Rule 457(o) under the Securities Act. Our Ordinary Shares are not traded on any national exchange and in accordance with Rule 457, the proposed maximum aggregate offering price was determined by multiplying 10,000,000 shares representing the shares to be offered by the assumed price of $3.60 per share.

Calculated pursuant to Rule 457(o) under the Securities Act.

    <ffd:OffsetExpltnForClmdAmt contextRef="ofst_1" id="ixv-432">On July 15, 2026, the registrant filed a registration statement on Form F-1 (File No. 333-297458)(the "Registration Statement"), which registered 5,000,000 Class A ordinary shares based on an offering price of $6.12 per share to register an aggregate of $30,600,000 Class A ordinary shares issuable under the Registration Statement, and paid a registration fee of $4,225.86. The registrant is now amending that Registration Statement to increase the offering to 10,000,000 Class A ordinary shares at a lower offering price of $3.60 pers share. Under the Registration Statement as amended hereunder, the registrant is issuing an aggregate of $36,000,000 Class A ordinary shares for a total registration fee of $4,971.60. As the registrant has already paid $4,225.86, this amount has been offset against the total fee and the registrant is paying the balance of $745.74.</ffd:OffsetExpltnForClmdAmt>
