The Member understands that the Odyssey Exchange Shares have not been and will not be registered under the Securities Act or any state securities laws by reason of specific exemptions under the provisions thereof which depend in part upon the investment intent of the Member and of the other representations made by the Member in this Agreement.

Accordingly, the Member understands that under the SEC’s rules, the Member may dispose of Odyssey Exchange Shares only in “private placements” which are exempt from registration under the Securities Act, in which event the transferee will acquire “restricted securities,” subject to the same limitations that apply to the Odyssey Exchange Shares in the hands of the Member. Consequently, the Member understands that the Member must bear the economic risks of the investment in the Odyssey Exchange Shares for an indefinite period of time. The Member further acknowledges that, under Rule 144, if the Member is not an affiliate of Odyssey, the Member must hold any Odyssey Exchange Shares acquired by the Member for a period of six months before the Member may sell any of such Odyssey Exchange Shares under Rule 144.

(c) The Member agrees: (i) that the Member will not sell, assign, pledge, give, transfer, or otherwise dispose of any Odyssey Exchange Shares or any interest therein, or make any offer or attempt to do any of the foregoing, unless the transaction is registered under the Securities Act and complies with the requirements of all applicable state securities laws, or the transaction is exempt from the registration provisions of the Securities Act and all applicable requirements of state securities laws; (ii) that the certificates representing the Odyssey Exchange Shares will bear the legend set forth in Section 4.06 making reference to the foregoing restrictions; and (iii) that Odyssey and its affiliates shall not be required to give effect to any purported transfer of any Odyssey Exchange Shares, except upon compliance with the foregoing restrictions.
