In connection with these special dividends, the Issuer's Board of Directors adjusted all options that were awarded, but not exercised, prior to the ex-dividend date for each special dividend to account for the effect of each special dividend. The number of shares subject to each such option was increased and the exercise price correspondingly decreased such that each option had the same fair value to the holder before and after giving effect to the payment of each special dividend.</footnote>
