Ann: Offer Document, Entitlement and Acceptance F, page-20

re: Ann: Offer Document, Entitlement and Acce... Assuming you hold some ORDR, Friday 30th is the last date you can sell them on the ASX, if that is what you want to do. Otherwise you have until the 10th April to exercise them (send money to ORD) to buy the shares.

This is what the Offer Document tells you, although not in those words.

So, if you are not going to send money to ORD by the 10th April, sell the ORDR on the ASX by close on Friday. Alternatively you will simply lose the entitlement and get nothing for it.
