Representations.

Rights Agreement, neither the Company nor any other person is under any obligation to register the Securities under the Securities
Act or any state securities laws or to comply with the terms and conditions of any exemption thereunder.

with investments in the securities of companies in the development stage such as the Company, is capable of evaluating the merits
and risks of an investment in the Securities and is able to bear the economic risk of an investment in the Securities in the amount
