Yu-Chiao HSIAO is no longer subject to Section 16 filing requirements. Form 4 or Form 5 obligations may continue.
*Note: This "Exit" Form 4 is voluntarily filed to report solely that the Reporting Person is no longer serving in the role as the Company's Secretary and Director, effective as of May 31, 2022, and therefore is no longer subject to Section 16 reporting. The Reporting Person did not have any transactions in the Issuer's securities during the time that she was a Section 16 reporting person and held 110,000 shares of the Company's common stock both at the time of filing her initial Form 3 and this voluntary "Exit" Form 4.
