BACKGROUND OF THE SOLICITATION

The Convening Shareholders propose to remove Hui Shao, Bo Tan, Ajit Shetty, Viren Mehta, Shaojing Tong and Rachel Yu as directors of the Company because such directors have taken actions that are not in the best interests of the Company and its shareholders.

We will give you a ballot when you arrive. You may vote in this manner regardless of whether you have voted by any of the other means.

The affirmative vote of not less than a simple majority (50.1%) of the votes cast by shareholders in person or by proxy at the EGM and entitled to vote on the ordinary resolutions is required to adopt the ordinary resolutions.

Only ordinary shares that are voted are taken into account in determining the proportion of votes cast for or against each resolution.
