standing under the Laws of the State of Delaware, and has the requisite corporate power and authority to own, lease and operate
its properties and assets and to carry on its business as it is now being conducted. Each of BioTime and the Merger Sub is duly
qualified or licensed as a foreign corporation to do business, and is in good standing, in each jurisdiction where the character
of the properties owned, leased or operated by it or the nature of its business makes such qualification or licensing necessary,

a BioTime Material Adverse Effect.
