Bill,
The financing vehicle would be neither S-8 nor a debenture of any kind.
It would be done as debt, not equity financing, thus no dilution to shareholders.
It's a very unique way to finance, and if CVIA were for real...an excellent way to finance their business plan.
The money wouldn't simply be handed over. It would be done in tranches along with the other comfort features I itemized in my post to Anglr that would protect the investment and by implication, the shareholders.
