Ann: Change in substantial holding from ZER, page-8

Selling on-market means you get your money in a couple of working days but if Zeta were to up their offer later you no longer have any entitlement to the increased offer amount from Zeta or if anyone else makes a better offer.

Selling off-market to Zeta through the letter they sent in the mail means waiting a month to get your money as a cheque in the mail.... but (assuming there are no clauses that I missed in their offer) you should be entitled to any increase Zeta may make later. However you still wouldn't be entitled to any better offers made by other parties.

Not selling at all......well IMO Zeta probably wouldn't want any 'hanger ons' so they may just try and buy on market upping their bid or make a formal off-market increase, or hold out at 3.8. Also probably depends on their time frame for what they are wanting to achieve. The other reason for not selling is waiting for a better offer from someone else........only time will tell on this one. With the amount of volume Zeta have purchased on market over the last week there are a number of people who dont believe any better offer is coming or they need the money.

All IMO so please DYOR.
