do yourself and me a favour in this great ipo, page-19

I've been looking & looking at this one. I agree sounds tight, if it's such a good deal the numbers would be easy to get on board must be reservations. This only brings in 20% new cap and min number new share holders, so what happens when surely at least some of the 80% held by existing investors decide to sell???
I'd rather pass up a dubious stag and position for a post IPO overhang affected day price.In this market and with the work ahead of them the $5m is going to run out pretty quick so post IPO has to price in future cap raising.
