Under the Delaware General Corporation Law, a shareholder has the right to put any proposal before the annual meeting of shareholders, provided it complies with the notice provisions in the corporate charter documents. A special meeting may be called by the board of directors or any other person authorized to do so in the governing documents, but shareholders may be precluded from calling special meetings. Cayman Islands law and our amended and restated articles of association allow our shareholders holding not less than one third of our paid up voting share capital to requisition a shareholders meeting. As an exempted Cayman Islands company, we are not obliged by law to call shareholders annual general meetings. However, applicable Nasdaq corporate governance rules require us to hold annual shareholder meetings.
