investment in the Company. 

 (e) The undersigned has been provided with all materials and information requested by the undersigned or
his or her representatives, including any information requested to verify any information furnished, and the undersigned has been provided the opportunity for direct communication between the Company and its representatives and the undersigned and

without registration or other compliance under the Act, and that the undersigned has no direct or indirect participation in any such undertaking or in the underwriting of such an undertaking. The undersigned understands that the securities have not
been registered, but are being acquired by reason of a specific exemption under the Act as well as under certain state statutes for transactions by an issuer not involving any public offering and that any disposition of the securities may, under
certain circumstances, be inconsistent with this exemption and may make the undersigned an “underwriter” within the meaning of the Act. The undersigned acknowledges that the securities must be held and may not be sold, transferred, or
otherwise disposed of for value unless they are subsequently registered under the Act or an exemption from such registration is available. The Company is under no obligation to register the securities under the Act, except as specifically provided
