Ms Hartley:

The 8k, I believe states the following…

The financial information required by this item, if any, with respect to the Merger, will be filed as soon as practicable, and in any event not later than 71 days after the date on which any Current Report on Form 8-K is required to be filed pursuant to Item 2.01. (b) Pro Forma Financial Information. The pro forma financial information required by this item, if any, with respect to the Merger, will be filed as soon as practicable, and in any event not later than 71 days after the date on which any Current Report on Form 8-K is required to be file pursuant to Item 2.01

My question is, will the company’s “practical “time be before the annual shareholder meeting or after? This is a very important move that the shareholders of PTSC would like to know the details of before the meeting.

Secondly how many more shares will have to be issued to satisfy the average pricing on the Crossflo acquisition, assuming there are not enough shares in the treasury stock balance to cover this acquisition? Will it be a combination of treasury and new stock (how much) and/or were preferred shares used at all?

Thank you for your assistance:
