TemekuT is correct, but way too gentle in suggesting you get immediate professional advice. No one in this deal is looking out for you, or even has the incentive to look out for your interests. There are several red flags waving and it really appears you are being rushed so as NOT to get outside advice.
Right now, you have the power. Start signing papers and you lose that leverage. Run, don’t walk, to get outside, impartial third party advice.
