For the avoidance of doubt, the Share Consolidation
has not taken place and will only take place if and when the Board has determined the exact Consolidation Ratio and that it is in the
best interest for the Company to do so, in which case the Company will announce its decision and provide the details in a press release.
As to the Share Redesignation, the Company intends to rely on the Nasdaq home country rule exemption. As a foreign private issuer, it
will follow Cayman Islands corporate governance practices instead of Nasdaq requirements under listing rule 5640. The Share Redesignation
will take place after all the requisite procedures are completed under rules, in which case the Company will announce its decision and
provide the details in a press release.
