In this particular case, no they do not have to buy back the shares. Here is why...
My company, Olibri Enterprises pays your company, Investmentventures LLC to do a particular task. We issue and then pay you 80 million shares of my company's stock.
The agreement is that these shares are Restricted until Jan 15th 2010, because we need to ensure that you will perform.
On December 1st of 2009, we determine that you have not lived up to your eld of the bargain. Now the shares HAVE been issued, but have not been "paid" for... your company failed to meet its obligation.
So our lawyers rescind the agreement, return the stock to company coffers then CANCEL it.
This part is perfectly legitimate. IF I WERE YOU, I WOULD INVESTIGATE WHO THE OTHER COMPANY WAS AND WHY THEY WERE PAID 80 MILLION SHARES OF STOCK.......
Our two worst enemies are Greed and Stupidity...
