Nituc,

You said "I wonder if any holders have forgotten they need to stump up the cash?"

Not necessarily, the options MAY be exercised (paid for to the company) by the end of the expiry date. And you have the amount of $62,500 right for 83,333 MAKO to convert to MAK fpo's.

But you don't have to, you can always sell them on market for whatever they are worth at the time, but they will stop trading before the expiry (a few days prior? someone may know this better then me).

Or you could just let them expire without doing anything, and the company won't get any of your money :-( Which, if they haven't got the heads above the exercise price in time, they won't deserve to get any of it anyway.
