TERMS AND CONDITIONS

In consideration of the foregoing and of the mutual covenants contained herein and other valuable consideration, the receipt of which is hereby acknowledged, the parties agree as follows:

1. Grant of Option.

(d) If at any time the Option is exercised and the Company does not have in effect, under the 1933 Act, and other applicable securities laws, a registration statement relating to the Option Shares and a prospectus meeting the requirements of the 1933 Act available for delivery to the Director, the Director hereby represents, warrants and covenants that the Director will acquire the Option Shares for investment and not with a view to distribution, sale or resale, and will comply with all applicable laws with regard to resale, including, but not limited to, Rule 144 under the 1933 Act.

(e) No exercise of the Option may be for less than one hundred (100) Option Shares, unless such lesser amount is the entire amount of the Option Shares available under the Option at the time of exercise.
