* If I elect to exercise by exchanging shares I already own, I will constructively return shares that I already own to purchase the new option shares. If my shares are in certificate form, I must attach a separate statement indicating the certificate number of the shares I am treating as having exchanged. If the shares are held in “street name” by a registered broker, I must provide the Company with a notarized statement attesting to the number of shares owned that will be treated as having been exchanged. I will keep the shares that I already own and treat them as if they are shares acquired by the option exercise. In addition, I will receive additional shares equal to the difference between the shares I constructively exchange and the total new option shares that I acquire.
