I'm assuming now we shouldn't give a damn about the EXT share price (if you're still holding) and instead concentrate on the KAH price on AIM. Let's just say for arguements sake, that KAH is the same price in 4-6 weeks time as it is today (big assumption I know but usually with these takeovers one companies price slides as holders feel they got a raw deal - EXT - and one companies shares rise as their holders feel they've got the better deal - KAH). That means if you bought EXT now at the offer of 93c you'd be guarenteed a 6% rise in approx 1 month. Probably too simlistic a view I know, but 6% in thhese volatile times isnt bad.
