Regarding collusion to aquire more than 10% of outstanding shares BUT avoiding reporting of same, a hypothetical example:

I am the one who wants the unreported shares and I already have just under the reportable amount, sooo...

<Hey Joe how about a memo of understanding? I give you an open account on which you can draw upon and buy up to 9.9% of Noront shares in your name at up to a price of a dollar per share. ( Assuming current Noront sp is $0.60) What ever price you buy you keep half the difference in cost between that cost and a dollar. ( so $1.00 - 0.60 = 0.40, you keep half i.e. 20 cents for each share of your service.) You must hold and hand over those shares at a time that I specify.>

What it means is that should the sp go to 80 cents, Joe gets only 10 cents from each share bought at that price. So it is in his interest to buy those shares at the lowest price possible to maximize his take. There could be a similar memo with Tom etc.

Highly hypothetical but I have seen effects with too many great stocks for this not to happen on occasion.
