The Purchaser is (i) sophisticated in financial matters and is able to evaluate the risks and benefits of the investment in the Purchased Shares and (ii) able to bear the economic risk of his investment in the Purchased Shares for an indefinite period of time because the Purchased Shares have not been registered under the Securities Act and therefore cannot be sold unless subsequently registered under the Securities Act or an exemption from such registration is available.
