Note 8. License Agreements

The Company has two license agreements with a third-party licensor covering the licensor’s “system know-how” technology with respect to the Company’s use of proprietary cell lines to manufacture new leronlimab material. The Company accrues annual license fees of £0.6 million (approximately $0.8 million utilizing current exchange rates), which fees are payable annually in December. Future annual license fees and royalty rate will vary depending on whether the Company manufactures leronlimab, utilizes the third-party licensor as a contract manufacturer, or utilizes an independent party as a contract manufacturer. The licensor does not charge an annual license fee when it serves as the

manufacturer. In addition, the Company will incur royalties of up to 0.75% to 2.0% of net sales, depending on who serves as the manufacturer, when the Company commences its first commercial sale; such royalties will continue for the duration of the license agreement. As of August 31, 2021 and May 31, 2021, the Company recorded a prepaid asset of approximately $0.1 million related to this arrangement.
