the option of the holder into one Class A ordinary share. Pursuant to Rule 13d-3(d)(1)(i)(D), the percentage in Row 11 is calculated
using the outstanding Class A ordinary shares only (assuming conversion of the 2,640,092 Class B ordinary shares held by Hybrid
Fund).&nbsp; If the outstanding number of shares included both Class A and B ordinary shares, this percentage would be 2.7%.</P>
