There IS something weird here. The debt also includes an additional $739,027 owed to the holder of the Shield note. According to the 8K filing on October 20th:
"The Shield note holder has agreed to convert all of its outstanding debt equal to $600,000 (approximately $740,000 including accrued interest) into preferred stock in the Company pending the result of the Company's possible litigation with the three remaining Note Holders who are the subject of the Company's investigation explained below."
That word "pending", under the current circumstances, is an important variable should the Shield note holder have a change of heart and convert.
