Subject to earlier vesting upon the occurrence of certain exit events, 25% of the Warrants will vest on the one year anniversary of the date of grant and the remaining 75% will vest at a rate of 1/36th per month from one year after the date of grant, subject to continued service.

After giving effect to the grant of the Warrants described above, warrants to subscribe for an additional 1,644,153 shares of the Company remain available for future grant by the Company’s board of directors pursuant to the Company’s Articles of Association.
