From Hawk Associates:

My interpretation is as follows, based on paragraph 6:

They "each hold Warrants to purchase common stock of the company"

"The Reporting Persons did not beneficially own more than 9.99% of the

Outstanding Common Stock"; "(Lincoln Ventures, LLC (“Lincoln”) and Swartz Private Equity, LLC (“SPE,” collectively the “Reporting Persons”),"

Investor Relations,

Have a question in interpreting the SEC filings regarding the # of PTSC shares owned by Lincoln Ventures and Swartz Private Equity. According to the SEC 13-G filed December 31, 2006 (see URL below); line 9 reports that the aggregate amount beneficially owned by each reporting person is 38,092,451 shares. This statement makes me believe that each entity, Lincoln Ventures and Swartz Private Equity owns 38,092,451 shares for a combined total of 76,184,902 PTSC shares. However, when reading line 6 of SEC 13-G, it states that Lincoln Ventures, LLC (Lincoln) and Swartz Private Equity, LLC (SPE, collectively the Reporting Persons), each hold Warrants to purchase common stock of the company. The term collectively the Reporting Persons makes me believe that they collectively own a total of 38,092,451 shares of PTSC stock as of the date this SEC form was filed. Can you please explain which is correct, do they jointly own 38,092,451 shares, or do they individually own 38,092,451 shares each? Your interpretation would be greatly appreciated.

Respectfully,

Craig
