Purchaser or to which Purchaser had access. 
 (d) Restricted Securities. Purchaser acknowledges and understands that: (a) the
offering and sale of the Purchased Shares will not be registered under the Securities Act; (b) the Securities will be “restricted securities” under the Securities Act because they are being acquired from Company in a transaction not
involving a public offering, and that under the Securities Act such securities may not be offered, sold or transferred unless they are duly registered or such offer or sale is made in accordance with an exemption from registration; (c) Company
is under no obligation to register any of the securities sold hereunder by the terms of this Agreement; and (d) if an exemption from registration or qualification is available, it may be conditioned upon various requirements including the time
