Well, as has been trawled over by many people over the past few weeks: they can't announce that meeting because the ASX won't let them without naming the buyer, so they are likely to try to complete one of the sales first, then negotiate with the ASX.
At that stage they may be forced to name the buyer or more likely the fact that first deal goes through removes the issue of the risk of completion and the ASX allows them to proceed with the meeting to vote on the second deal without naming the buyer.
They are dealing with the notes separately - can't imagine note holders voting against this - it doesn't materially affect their rights, they can select to redeem in March if the deals fall through, maybe $2m more cash burned, not much else will change..
