Cliffy has agreed to the takeover price (sold out in my view but that's another story - either he didn't care or got pressured into it or (believe it or not) he thinks he has done right by all of us.
If the holders vote no or the independent expert comes up with a higher valuation, then Cliffy is finished - not just at AGO but probably elsewhere as well.
Not that it matters as he has > 120 Million shares so he will get more than he can easily spend out of this - even if he never works again
So he is running around trying to push the takeover through so he can be the hero and get an even better job elsewhere.
