Ann: Response to ASX Aware Query, page-138

I very much doubt you can sell escrowed shares except under one of the exceptions in the Prospectus such as a takeover.

The whole point of them being escrowed is that you can't sell them.
If FFX is allowed to sell escrowed shares, then the new owner could equally sell the escrowed shares which would make a total mockery of them being escrowed.
