"I have had many an experience of not being able to covert oppies.
FAR EMR and also PEK"

How come? I thought company that opens the options must have some certain quotas for options to be converted.

If we couldn't convert oppies, what happens to our money since we have paid for them?

I'm thinking to convert my ordinary share to oppies to get more percentage of profit since it's lower price, is that worth it?
