The Performance Warrants vest contingent upon the occurrence of the following four specified performance milestones: - Milestone 1: 500,000 Performance Warrants shall vest upon the Issuer completing and receiving the results of a three-month collagen study conducted in Boston, Massachusetts; - Milestone 2: 500,000 Performance Warrants shall vest upon the Issuer listing its shares of Common Stock on the Nasdaq Stock Market, LLC, or any other recognized stock exchange in North America; - Milestone 3: 500,000 Performance Warrants shall vest upon the Issuer's listed shares of Common Stock trading for at least 20 consecutive trading days at a market capitalization of $80,000,000 or greater on a recognized North American stock exchange on which the shares of Common Stock are listed; and - Milestone 4: 500,000 Performance Warrants shall vest upon the Issuer's submission of a 510(k) application to the U.S. Food and Drug Administration. On July 8, 2025, Milestone 1 was achieved upon the Issuer completing and receiving the results of the three-month collagen study, resulting in the vesting of 500,000 Performance Warrants with respect to Milestone 1.
