RECITALS:

(A) On 18 November 2024, the Lender and the Borrower, among others, entered into a stock purchase agreement pursuant to which the sellers thereunder (including the Borrower) agreed to sell and the Lender agreed to purchase shares in Quality Industrial Corp. on the terms set out in that agreement (the “Stock Purchase Agreement”).

(B) By virtue of the terms of the Stock Purchase Agreement, the Borrower is a shareholder of the Lender.

(D) During February and March 2026, the Lender has made payments totaling US$100,000 to entities related to the Borrower (collectively, the “ILUS Related Payments”).

(E) In consideration for the ILUS Related Payments, the Borrower has agreed to: (i) extend the Extended Purchaser Meeting Deadline (as defined in the Stock Purchase Agreement) to 30 June 2026; and (ii) procure that the other Sellers (as defined in the Stock Purchase Agreement) agree to extend the Extended Purchaser Meeting Deadline to 30 June 2026, on the terms and subject to the conditions set out in this Agreement. This extension does not excuse the lender from meeting its obligations as soon as it is technically possible to do so and the lender does not have a matter of choice as to when it chooses to meet its stock purchase obligations, it must do so immediately that it is technically able to. A Further extension will not be granted. The lender must under no circumstances whatsoever intentionally delay the process and must do everything within its power to meet the stock purchase agreement obligations as soon as possible.
