Under the terms of the LFB License Agreement, we have acquired the exclusive worldwide rights (exclusive of France/Belgium) for the development and commercialization of ublituximab. As of September 30, 2022, we have incurred approximately $13.0 million in expense related to the achievement of certain milestones of the LFB License Agreement. LFB Group is eligible to receive future payments of up to an aggregate of approximately $18.0 million upon our successful achievement of certain regulatory milestones, in addition to royalty payments on net sales of ublituximab at a royalty rate that escalates from mid-single digits to high-single digits. The license will terminate on a country-by-country basis upon the expiration of the last licensed patent right or 15 years after the first commercial sale of a product in such country, unless the agreement is earlier terminated (i) by LFB if the Company challenges any of the licensed patent rights, (ii) by either party due to a breach of the agreement, or (iii) by either party in the event of the insolvency of the other party. In November 2012, we entered into an exclusive (within the territory) sublicense agreement with Ildong Pharmaceutical Co. Ltd.

Additionally, Rhizen receives tiered royalties that escalate from high single digits to low double digits on any net sales of umbralisib and any New Product. During the three months ended September 30, 2022 the worldwide royalty due under the Umbralisib License recorded by the Company in cost of product revenue based on U.S. sales of UKONIQ was immaterial . During the nine months ended September 30, 2022, the Company recorded $0.2 million of royalties due under the Umbralisib License in cost of product revenue. As of September 30, 2022, approximately $4,700 in royalties were payable under the Umbralisib License and as of December 31, 2021, $0.2 million in royalties were payable under the Umbralisib License. Rhizen will also be eligible to participate in sublicensing revenue, if any, based on a percentage that decreases as a function of the number of patients treated in clinical trials following the exercise of the license option. Rhizen will retain global manufacturing rights to umbralisib, provided that they are price competitive with alternative manufacturers. The license will terminate on a country-by-country basis upon the expiration of the last licensed patent right or any other exclusivity right in such country, unless the agreement is earlier terminated (i) by us for any reason, or (ii) by either party due to a breach of the agreement.
