They need to give at least 5 days notice for the second creditors meeting, so expect another extension.

"In preparation for the second meeting, the voluntary administrator must send creditors the following documents at least five business days before the meeting:
- a notice of meeting
- the voluntary administrator’s report, and
- a statement about any proposals for a deed of company arrangement.
These will be accompanied by:
- a claim form (usually a ‘proof of debt’ form), and
- a proxy voting form.
The meeting must also be advertised."
