below is a few questions & answers from PTSC IR

I have been long with xxx,xxx shares for several years now and have a couple questions:

• Can you please share with me any timelines on expected USPTO review results for '336, '148 & '584?
• Is a change to NASDAQ or AMEX still in the offing per several shareholder letters of recent years?
• If yes, would it be via share price qualification or merger/acquisition of other publically traded company?
• How do the latest mergers/equity stakes fit into Patriot's overall strategic plan to enhance shareholder value?

Thank you for your time.

Best,

XXXX

Dear Mr. XXXXX:

I will need to get more information to answer your first question and will get back to you on that shortly.

Obviously it would be to our advantage to become listed on an exchange and we will continue to pursue that. I believe the most likely route would be share price qualification, but would never rule out any alternative.

Re your final question. We see the advantage in having an operational arm of the company to achieve robust growth. To that end, we have increased our investment in Talis and are moving toward the acquisition of Crossflo, as noted in recent announcements. Both companies have unique approaches to related market niches. Our goal would be to provide those companies with the resources and the synergy of other similar solution providers we are taking a look at, and create a portfolio of companies that can offer products and services to a growing market.

If you have not already, please read the CEO's recent letters to shareholders on the PTSC website. I believe these transactions will demonstrate PTSC's commitment to delivering on their stated strategic goals.

Best regards,

Angela Hartley
