Corporations Act. Such a withdrawal right will arise if, after
you have accepted the Offer, the Bidder varies the Offer
in a way that postpones, for more than one month, the
time when the Bidder has to meet its obligations under the
Offer (for example, if the Bidder extends the Offer for more
than one month while the Offer remains conditional).
