Securities Act and state securities laws applicable to such disposition).

investor,” as that term is defined in Rule 501(a) of Regulation D under the

have delivered to the Company evidence reasonably satisfactory to the Company
indicating that the Exchange Shares to be sold or transferred may be sold or

representing the Exchange Shares and enter a stop-transfer order against the
transfer of such certificates.

constitute, or upon execution thereof will constitute, valid and binding
obligations of such Holder, enforceable against such Holder in accordance with
their terms, except as such enforcement may be limited by bankruptcy, insolvency
and other similar laws affecting the enforcement of creditors’ rights generally
and except as enforcement thereof is subject to general principles of equity.

Section 3.8 Consents: No Violations. Neither the execution, delivery or
performance by such Holder of this Agreement or the Exchange Transaction
Documents nor the consummation of the transactions contemplated hereby or
thereby shall (a) in the case of any Holder that is not a natural person,
conflict with, or result in a breach or a violation of, any provision of the
