Thanks Wilma85

Pg14) Each Option can be exercised at the Option Price from the issue date of the Options (the Option Issue Date). Options expire on the earlier of the date that they are exercised or, if they are not exercised, on 7:00pm (NZ time) on the date which is 5 years after the Option Issue Date (Option Expiry Date). Options are exercisable by the holder lodging with the Registry a notice in writing of exercise of Options together with payment of the Option Price for all Options being exercised. Options can be exercised in minimum parcels of 100,000 (or any smaller number which represents all of the holder’s Options).
