Ann: Greencross enters into Scheme Implementation Agreement, page-5

They're worried some (or one in particular) shareholder will disapprove - maybe it was CCL that negotiated the equity option 2, and they intend to continue holding their 10% stake? They must have acquired to prevent a compulsory acquisition scenario. Strongly suspect that on this basis the deal will go through.

Maybe there is more long term value in this company, but will also be relieved to just bank the quick gain (fingers crossed). My purchases a few months ago feel a bit less stupid now
