Sundance has done a deal with ANS. Because ANS has to show, that it is no fake-deal, they need to provide information and confirmation to ASX, that shows, that the (possible) new investor will be able to finance the deal (Warpac and valid/extended also for the other new investor).

So, what, if ANS can't provide the needed information: The deal must be canceled. And thereafter, both companies can do "business as usual", or not? And if not, why not?

I'd say that Sundance (in that case) hasn't failed. So, why should there not be normal trading after that?
