B-

I have not been able to find any factual evidence to support an exclusive arrangement with HP, or not, leaving open the possibility, in my opinion, of either condition being the case. I choose to "guess" at this time that Crossflo's arrangement with HP is not exclusive. Either way, we are both guessing until the facts tell us otherwise.

I suspect that we are in the early stages of the development of this business with Crossflo at the core, and that is where I find my optimism. Affording PTSC time to develop this business is difficult for many, and I can see why, given the history of disappointments. One year from now I expect to look back and see my investment as a smart move. Just one person's opinion and position.

Cheers,

DG
