Pursuant to the IBM Agreement, IBM has agreed to license the Programs to the Company for two payments of $18,935,564 and $4,729,730, respectively (the “Program Payments”). On September 22, 2025, the Company and IBM entered into an amendment (the “IBM Amendment”) to the IBM Agreement. Pursuant to the IBM Amendment, upon a payment of $2,500,000 to IBM towards the Program Payments, the due dates and amounts for the remaining Program Payments will be revised and consist of the first payment of $3,296,183, which will be due on December 23, 2025, and eight subsequent payments, each in the amount of $2,183,676 and due on each of March 23, June 23, September 23 and December 23 in 2026 and 2027. Pursuant to the IBM Amendment, the one-year committed term of the Programs referred to in the IBM Agreement as “Fixed Quantity Subscription License Programs” is scheduled to start on September 30, 2025, two months sooner than previously agreed.
