Optionee hereby confirms that Optionee has been informed that the Purchased Shares are restricted securities under the 1933 Act and may not be resold or transferred unless the Purchased Shares are first registered under the Federal securities laws or unless an exemption from such registration is available. Accordingly, Optionee hereby acknowledges that Optionee is prepared to hold the Purchased Shares for an indefinite period and that Optionee is aware that SEC Rule 144 issued under the 1933 Act which exempts certain resales of unrestricted securities is not presently available to exempt the resale of the Purchased Shares from the registration requirements of the 1933 Act.

2. Restrictions on Disposition of Purchased Shares. Optionee shall make no disposition of the Purchased Shares unless and until there is compliance with all of the following requirements:

(i) Optionee shall have provided the Corporation with a written summary of the terms and conditions of the proposed disposition.

(ii) Optionee shall have provided the Corporation with written assurances, in form and substance satisfactory to the Corporation, that (a) the proposed disposition does not require registration of the Purchased Shares under the 1933 Act or (b) all appropriate action necessary for compliance with the registration requirements of the 1933 Act or any exemption from registration available under the 1933 Act (including Rule 144) has been taken.

The Corporation shall not be required (i) to transfer on its books any Purchased Shares which have been sold or transferred in violation of the provisions of this Agreement or (ii) to treat as the owner of the Purchased Shares, or otherwise to accord voting, dividend or liquidation rights to, any transferee to whom the Purchased Shares have been transferred in contravention of this Agreement.

3. Restrictive Legends. The stock certificates for the Purchased Shares shall be endorsed with one or more of the following restrictive legends:

“THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933. THE SHARES MAY NOT BE SOLD OR OFFERED FOR SALE IN THE ABSENCE OF (A) AN EFFECTIVE REGISTRATION STATEMENT FOR THE SHARES UNDER SUCH ACT, (B) A “NO ACTION” LETTER OF THE SECURITIES AND EXCHANGE COMMISSION WITH RESPECT TO SUCH SALE OR OFFER OR (C) SATISFACTORY ASSURANCES TO THE CORPORATION THAT REGISTRATION UNDER SUCH ACT IS NOT REQUIRED WITH RESPECT TO SUCH SALE OR OFFER.”

C. MISCELLANEOUS PROVISIONS
