(2) Estimated solely for purposes of calculating the amount of the registration fee pursuant to Rule 457(o) under the Securities Act.

(3) The registrant may issue pre-funded warrants to purchase ordinary shares in the offering. The purchase price of each pre-funded warrant will equal the price per share at which ordinary shares are being sold to the public in this offering, minus $0.0001, which constitutes the pre-funded portion of the exercise price, and the remaining unpaid exercise price of the pre-funded warrant will equal $0.0001 per ordinary share (subject to adjustment as provided for therein). The proposed maximum aggregate offering price of the ordinary shares will be reduced on a dollar-for-dollar basis based on the offering price of any pre-funded warrants issued in the offering, and the proposed maximum aggregate offering price of the pre-funded warrants to be issued in the offering will be reduced on a dollar-for-dollar basis based on the offering price of any ordinary shares issued in the offering. Accordingly, the proposed maximum aggregate offering price of the ordinary shares and pre-funded warrants (including the ordinary shares issuable upon exercise of the pre-funded warrants), if any, is $5,000,000.
