a) resolution 1 is voting for the amended scheme booklet increasing the offer to 20.8c.
b) resolution 2 is voting for or against the takeover.
If you vote No to both you have rejected the takeover offer. If you vote yes to both you have accepted the offer.
Voting yes to resolution 1 is irrelevant if you are voting NO to resolution 2. The takeover doesn't happen if the NOs are successful.
