Convertible Debenture financial
"The 8% Convertible Debenture Due August 21, 2029 (the "Convertible Debenture")"
A convertible debenture is a long-term loan a company issues that pays interest like a bond but can be turned into a set number of the company’s shares under pre-agreed terms. For investors it matters because it mixes safety and upside: you get regular interest and higher repayment priority like a lender, yet you also hold an option to become a shareholder if the stock rises, which can dilute existing owners and change risk and return profiles.
Certificate of Designation regulatory
"subject to the Company receiving shareholder approval and filing the Certificate of Designation"
A certificate of designation is a formal document that spells out the specific rights and rules attached to a particular class or series of stock, usually preferred shares. Think of it as a rulebook or menu that lists dividend terms, liquidation priority, conversion or redemption rights and any special voting protections; investors use it to judge how much income, control or downside protection those shares will provide compared with other securities.
Series A-1 8% Convertible Preferred Stock financial
"convert into shares of the Company's Series A-1 8% Convertible Preferred Stock"
beneficial ownership limitation regulatory
"subject to a beneficial ownership limitation of 9.99% of the outstanding shares"
A beneficial ownership limitation is a rule that caps the percentage of a company’s shares an investor can be treated as owning or controlling for voting, regulatory or tax purposes. It matters to investors because it can restrict how many shares a person or group can buy or vote, affect takeover chances, and influence share liquidity and value — like a speed limit that prevents any single driver from taking over the whole road.
Common Stock Purchase Warrant financial
"The Common Stock Purchase Warrant (the "Warrant") is exercisable for an aggregate"
A common stock purchase warrant is a tradable certificate that gives its holder the right to buy a company’s common shares at a fixed price for a set period. Think of it as a coupon that lets you buy stock later at today’s agreed price; it can amplify gains if the share price rises but also can increase the total number of shares outstanding, which may reduce existing owners’ percentage of the company. Investors watch warrants because they offer leveraged upside and can affect future share value and ownership.
Rule 13d-3 regulatory
"may be deemed to beneficially own the Derivative Securities for purposes of Rule 13d-3"
Rule 13d-3 defines who is treated as the beneficial owner of a company’s shares for U.S. securities disclosure rules — essentially anyone who has the power to vote or direct how shares are voted, or the power to buy or sell them, even if they don’t hold the certificates. For investors this matters because crossing certain ownership thresholds triggers public filing and disclosure obligations and signals potential control or influence, much like having the keys to a car implies you can drive it even if it’s registered to someone else.
