The proposed maximum offering price per share and the proposed maximum aggregate offering price are based on the average of the high and low sale prices of the registrant&#x2019;s ADSs on the Nasdaq Capital Market on September 9, 2026, or $2.08, divided by 300 (to give effect to the 300:1 ratio of ordinary shares to ADSs).&lt;br/&gt;</ffd:OfferingNote>
