JMHO: Zimbler has apparently not been associated with ENZC in years and not mentioned at all since the merger with BioClonetics in November 2020. I don't see any current payments to him. Where are you getting that?
Looking back at the notes to the financials, it looks like the balance due to him grew over several years in varying amounts, such as 14-20K per year to the final and current balance of $142,646 by the end of 2018 with an increase of only $1.1K since 2017. The company was doing business as ECO-PETROLEUM SOLUTIONS, INC. during most of that time, filing as Enzolytics, Inc. for the first time in 2018.
I don't see the reason for the debt, but it is unsecured, non-interest bearing and there is no due date. Same with Harry's $200+K. After so many years with no obligation to pay and no interest due, it looks more like "paid-in Capital" to me. https://www.otcmarkets.com/otcapi/company/financial-report/262124/content
