Appointment of President

On June 27, 2022, the Company entered into an employment agreement with Cyrus Arman, Ph.D. (the “Employment Agreement”), under which he has been employed as the Company’s President on an at-will basis beginning on July 9, 2022. Antonio Migliarese, who was appointed as interim President on January 24, 2022, ceased to be President on July 9, 2022, and will continue in

his roles of Chief Financial Officer, Corporate Secretary and Treasurer, as well as serving as the Company’s principal accounting officer.

Special Stockholders’ Meeting

On July 8, 2022, the Company issued a notice for a special stockholders’ meeting to be held on August 31, 2022, to seek approval of a proposal to increase the total number of authorized shares of common stock from 1,000,000,000 to 1,350,000,000 shares. The proposal to increase the number of shares of common stock authorized for issuance, if approved at the special meeting, will become effective, and the Company’s authorized shares of common stock will be increased to 1,350,000,000 shares, upon the filing of the certificate of amendment with the Secretary of State of the State of Delaware. The Board believes that it is essential to the Company’s continued operations to have additional authorized shares of common stock available for future issuance; the authorization of a pool of additional shares of common stock at the special meeting will provide the Company with ability to use these shares to meet the Company’s business and financial needs without the expense and delay of another special stockholders’ meeting. These needs include: (i) satisfaction of the Corporation’s existing obligations to issue shares of common stock for which authorized shares are not currently available, (ii) future financings to raise the capital needed to operate the Company’s business, including potential negotiations with third parties to satisfy the Company’s existing payment obligations in shares of common stock rather than cash; (iii) possible acquisition or other strategic transactions or partnerships; (iv) future equity awards as compensation for employees, officers, directors, consultants and advisors, including equity incentives for performance; and (v) other general corporate purposes. Although such issuances of additional shares would dilute existing stockholders, the Board believes that such transactions would increase the overall value of the Company to its stockholders. In addition, the Board believes the Company’s success depends in part on its continued ability to attract, retain and motivate highly qualified management and clinical and scientific personnel and advisors, as well as independent directors with requisite skills and experience.

Issuance of Shares to Former Executive Officer and Former CEO

The Company issued to a former executive officer a total of 69,040 shares of common stock to satisfy its obligation to make severance payments for the payroll periods ended June 15, June 30, July 15, and July 31, 2022, net of payroll deductions and withholding taxes. Consistent with the terms of our former CEO’s employment agreement, in August 2022, the Company issued 26,106 shares of common stock in satisfaction of the severance amount due for the month of July 2022. The number of shares issued was based on the closing price of the common stock on the applicable date.
