Rainmaker Promissory Note

In September 2020, the Company entered into a Senior Secured Convertible Promissory Note with Rainmaker Worldwide Inc. (the “Rainmaker Note”). The Rainmaker Note is secured as a registered lien under the Uniform Commercial Code and the Personal Property Security Act (Ontario) against the assets of Rainmaker. In January 2025, the Company and Rainmaker entered into Amendment No. 4 to the Rainmaker Note and the principal amount was revised to $4.6 million.

In January 2026, the Company and Rainmaker entered into a settlement agreement to the Rainmaker Note and both parties agreed the outstanding amount would be settled by a one-time payment of $0.5 million by February 27, 2026 (the “Settlement Date”). Such payment was not received by the Settlement Date, and based on the settlement agreement, the amount increases by $50,000 the first business day of each month following the Settlement Date. All amounts related to the Rainmaker Note have been fully reserved.
