The notice shall state the number of Shares as to which the Option is being exercised and shall be accompanied by payment of the exercise price. Payment of the exercise price shall be made # in cash (including bank check, personal check or money order payable to the Company), # with the approval of the Company (which may be given in its sole discretion), by delivering to the Company for cancellation shares of the Company’s Common Stock already owned by Participant having a Fair Market Value equal to the full exercise price of the Shares being acquired, or # with the approval of the Company (which may be given in its sole discretion), by delivering to the Company a combination thereof.
