B. Investor understands that the Warrant and the Shares have not been registered under the Securities Act by reason of their issuance in a transaction exempt from the registration and prospectus delivery requirements of the Act pursuant to Section 4(2) thereof, they must be held by the Investor indefinitely, and Investor must therefore bear the economic risk of such investment indefinitely unless a subsequent disposition thereof is registered under the Act or is exempted from such registration.
