Share Sale Facility.

Just had a read of the announcement and want to check I am on the right track. If anyone with a better understanding of it could confirm it for me that would be great.

If Alliance intends to implement a Share Sale facility, then after the merger won't they just offer to buy you shares at SGX-ST market price equivalent? If that is the case, why are people talking of selling tomorrow at lower prices, when they will most like be able to participate in the Share Sale Facility?

Thanks in advance,
Cheers
