There was an attorney in a class at S5, his opinion, FWIW, was that the "contract" wasn't worth the paper it was printed on for a variety of reasons not the last if which IIRC was the form of how it was drawn up, which I gather in Promissory Notes is right important. All that being said, I'm just going off memory of what he said in the break room at the training center. Consult an attorney, see what answer you get, and post it back here; it'll be interesting to see what comes of it all.
