exercising this option) for investment purposes and not with a view to resale or distribution,
except that such condition will be inoperative if the Option Shares are registered under the
Securities Act of 1933, as amended, or if in the opinion of counsel for the Company such shares may
be resold without registration. At the time of any exercise of the option, the Optionee (or other
person exercising this option) will execute such further agreements as the Company may require to
implement the foregoing condition and to acknowledge the Optionees (or such other persons)
familiarity with restrictions on the resale of the Option Shares under applicable securities laws. 5. DISPOSITION OF SHARES.The Optionee or any other person who may exercise this
