Advice to shareholders

I see that at the recent EGM approval was given to the acquistion - but there are still various conditions to be satisfied before the shares are delisted. What percentage of approvals does MAS need to delist - is it 90%? MAS has not issued any statement on the overall approvals to date (other than what was voted for at the EGM). Should ordinary shareholders hang on in case Vertex needs to increase its offer to buy out enough ordinary shareholders to achieve the 90% to compulsory acquire the remainder?
