Stock Option (Right to Buy) $ 0.0209 01/12/2026   J (2)   3,330,332   01/12/2026 (1) 01/12/2031 Common Stock 3,330,332 $ 0 3,330,332 (3) I through 2752128 Ontario Ltd.
Explanation of Responses:
1. The option vests in equal monthly installments over twenty-four months from January 12, 2026, subject to the award terms. This replaces the unqualified grant-date exercisability entry. The contractual expiration date is January 12, 2031.
2. This amendment changes code A to J without asserting a Rule 16b-3(d) exemption. The 3,330,332-share grant, $0.0209 exercise price, five-year term and indirect ownership are unchanged.
3. Subsequently, effective April 30, 2026, the unvested portion was forfeited and the holder surrendered all vested and outstanding portions without payment, replacement award or other consideration. No options under this award remained outstanding after that date. The 3,330,332 ending balance above is historical, immediately after the January grant.
Remarks:
The relationship boxes reflect Ms. White's current director and financial-officer positions, effective September 21, 2026, and her continuing greater-than-10% ownership. At the transaction date she reported as a greater-than-10% owner; this report does not assert a historical Rule 16b-3 exemption.
