Shareholders can pay for their placement using Bpay, credit card etc.
Expired option holders can apply for shortfall using the expired optionholder application form, but that has to be done by snail mail, for expired option holders you don't have to apply by today, you can send in next week (read carefully, there is no deadline)
You should email the company for a proper answer, I could be lying so you dont take up your shortfall, so the big boys, Lundin and Faroole can underwrite it.
