Will someone in the know please set me straight on

Will someone in the know please set me straight on the "quiet" period restrictions for an IPO? First, does the silence extend to the fact of the filing being made, without reference to terms or price. I would be surprised if it does but maybe I am wrong. Second, if Joe is referring everyone to Dawson James, if within this restrictive period, are they not an agent of GNBT for purposes of IPO sealing their lips as well, If I am enlightened to the point of learning Joe's dilemma, I stand corrected on my criticisms.
