Note 9. 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 (PRO 140) 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 (PRO 140), 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 upon who serves as the manufacturer, when the Company commences its first commercial sale, which will continue as long as the license agreement is maintained.
