Lets not get too comfortable with "they will be in trouble if they benefitted from inside info" 

Being on the inside of a negotion before its concluded can give them a sense of whats happening and therefore they may have decided its best to sell now.

If the negotiaitions conclude to the detriment of Aurelian shareholders it will be virtually impossible to prove anything was conclusive at the time of the insider sales.

These guys will know the law and will do things in a way that is "legal".

Most insider share sales that are done prior to a stock price decline conclude in the insiders getting off fine and with their money.

I dont know that things are going bad but the timing of this is really bad
