Founders Agreement Effective December 8, 2022, the Company entered into a Founders Agreement with Nexcella (the “Nexcella Founders Agreement”). The Nexcella Founders Agreement provided that prior to a Qualified IPO (as defined in Nexcella’s Amended and Restated Certificate of Incorporation, as amended (the “Nexcella COI”)) or Qualified Change in Control (as defined in the Nexcella COI), the Company shall provide funds to Nexcella as requested by Nexcella, in good faith, to be evidenced by a senior unsecured promissory note. In exchange for the time and capital expended in the formation of Nexcella and the identification of specific assets, the acquisition of which benefit Nexcella, on December 21, 2022, the Company loaned Nexcella approximately $2.1 million, evidenced by a senior unsecured promissory note, representing the up-front fee required to acquire Nexcella’s license agreement with Hadasit Medical Research Services & Development, Ltd. (“HADASIT”) and BIRAD Research and Development Company Ltd. (“BIRAD”), and for use as working capital for its research and development activities. The note, which had a maturity date of January 31, 2030, accrued interest at a rate of 7.875% per annum and was convertible into shares of common stock of Nexcella at a conversion price of $2.00 per share, subject to adjustment; provided, however, that such note shall automatically convert into shares of Nexcella common stock immediately prior to certain conversion triggers set forth in the note.

In addition, upon a Qualified IPO (as defined in the Nexcella COI) or Qualified Change in Control (as defined in the Nexcella COI), each share of Class A Common Stock would automatically convert into one fully paid and nonassessable share of Nexcella’s common stock; provided however, if at that time, the Class A Common Stock was not then convertible into a number of shares of Nexcella common stock (or such other capital stock or securities at the time issuable upon the conversion of the Class A Common Stock) that have a value of: (a) in the case of a Qualified IPO, at least $5,000,000 based on the initial offering price in such initial public offering, or (b) in the case of a Qualified Change in Control, at least $5,000,000 in cash or at least $5,000,000 of equity based on the implied value of a share of Nexcella common stock resulting from the price paid upon the consummation of such Qualified Change of Control, the Class A Common Stock would automatically convert into such number of shares of Nexcella common stock (or such other capital stock or securities at the time issuable upon the conversion of the Class A Common Stock) that have a value of $5,000,000 based on the initial offering price in such initial public offering or the implied value of a share of Nexcella common stock resulting from the price paid upon the consummation of such Qualified Change of Control (or if such Qualified Change of Control results in the Class A Shares being exchanged solely for cash, then $5,000,000 in cash). The Company was entitled to cast such number of votes equal to the number of whole shares of Nexcella common stock into which the Company’s Class A Common Stock was convertible as of the record date for determining stockholders entitled to vote on matters presented to the stockholders of Nexcella. In addition to the foregoing, the Company was entitled to one vote for each share of Nexcella common stock held by it. Except as provided by law or by the Nexcella COI, holders of Nexcella Class A Common Stock and Class A Preferred Stock shall vote together with the holders of Nexcella common stock, as a single class.

At the request of the Company, Nexcella utilized clinical research services, medical education, communication and marketing services and investor relations/public relation services of companies or individuals designated by the Company, provided those services are offered at market prices. In consideration for the Services, Nexcella paid the Company an annual base management and consulting fee of $500,000 (the “Annual Consulting Fee”).
