In consideration for the immediate exercise of the preferred investment options for cash, the Company will issue new unregistered Series A Ordinary Share Preferred Investment Options (the "Series A Preferred Investment Option") to purchase up to an aggregate of 548,000 Ordinary Shares and new short-term unregistered Series B Ordinary Share Preferred Investment Options (the "Series B Preferred Investment Option," together with the Series A Preferred Investment Option, the "New Warrants") to purchase up to an aggregate of 1,096,000 Ordinary Shares. The New Warrants will have an exercise price of $6.00 per Ordinary Share.
