Based on my recollection of the Master Agreement, Patriot must get approval from TPL on all PR's related to licensing deals. IMO TPL would have no say in regards to the web cast that was cancelled.
I believe the thought process here is that if negotiations are indeed taking place and close to conclusion, than out of respect to the J's, as well to be sure that no one accidentally stated something confidential on a web cast, that the smart/safe road was/is to have a quiet period until such negotiations have been completed and announced.
All in my opinion. Good luck to you, me, us, and all longs.
