     (2)  The Company granted options representing 871,775 shares to employees
          in 1999.
     (3)  Option exercise price is determined as the close price on the date of
          grant.
     (4)  The potential realizable value is calculated based on a ten year term
          of the option at its time of grant and is calculated by assuming that
          the price on the date of grant as determined by the Board of Directors
          appreciates at the indicated annual rate compounded annually for the
          entire term of the option and that the option is exercised and sold on
          the last day of its term for the appreciated price. The 5% and 10%
          assumed rates of appreciation are derived from the rules of the
          Securities and Exchange Commission and do not represent the Company's
          estimate or projection of the future Common Stock price.
