Notice of Delisting		On June 1, 2020, AgeX received a letter (the "Deficiency Letter") from the staff of the NYSE American (the "Exchange") indicating that AgeX does not meet certain of the Exchange's continued listing standards as set forth in Section 1003(a)(i) of the Exchange Company Guide in that AgeX has stockholders equity of less than $2,000,000 and has incurred losses from continuing operations and/or net losses during its two most recent fiscal years. Pursuant to Section 1009 of the Exchange Company Guide and as provided in the Deficiency Letter AgeX provided the Exchange staff with a plan (the "Compliance Plan") advising the Exchange staff of action AgeX has taken and will take that would bring AgeX into compliance with the Exchange's continued listing standards by December 1, 2021. The Exchange staff has accepted the Compliance Plan. The Exchange staff will review AgeX's compliance with the Compliance Plan on a quarterly basis and if AgeX does not show progress consistent with the Compliance Plan or is not in compliance with the Exchange's continued listing standards by December 1, 2021, the Exchange will commence delisting procedures. If the Exchange staff determines that AgeX is not in compliance with the Compliance Plan at any time, the Exchange staff will promptly initiate delisting proceedings.
