I suggest you contact a contract attny, who specialize in contracts and ask for their advice on both contracts..
Lets put it this way - I did , the best 500 i spent, and based on there findings with a ton of DD for backup with a 2 hours conference of sitting down with documents in hand for explantions - and there stuff that hasnt come to light yet -- based on the info I sold all of my holdings in TTDZ!
Im no was a basher - but I do Complete DD on all companies I invest in..
