*    Less than one percent (1%)

     (1)  The  number of shares of  non-voting  common  stock  deliverable  upon
          exchange   of  the  LYONs  are   subject  to  change   under   certain
          circumstances  described in the indenture  governing  the LYONs.  As a
          result,  the number of shares of non-voting  common stock  deliverable
          upon exchange of the LYONs may increase or decrease at any time.

     (2)  Assumes that the full amount of LYONs held by a selling stockholder is
          exchanged for shares of non-voting common stock at an exchange rate of
          14.3657 shares of non-voting  common stock per $1,000 principal amount
          at maturity of LYONs,  and that all shares  received upon exchange are
          offered hereunder by that selling  stockholder.  Since exchange of the
          LYONs for shares of non-voting  common stock is  conditioned  upon the
          occurrence of specified  events,  and since Eaton Vance Management has
          the  right  to pay cash in lieu of  delivering  shares  of  non-voting
          common stock upon exchange, there can be no assurance that any selling
          stockholder  will be  able  to  exchange  its  LYONs,  or that it will
          receive shares of non-voting common stock upon any such exchange.

     (3)  Calculated  based on Rule  13d-3(d)(1)(i)  of the Exchange Act,  using
          69,162,424  shares  of  non-voting  common  stock  outstanding  as  of
          December  31, 2002.  In  calculating  this amount for each holder,  we
          treated as outstanding the number of shares of non-voting common stock
          deliverable  upon exchange of all of that holder's  LYONs,  but we did
          not assume exchange of any other holder's LYONs.

     (4)  Information  about  other  selling  stockholders  will be set forth in
          future prospectus supplements, if required.

     (5)  Merrill Lynch,  Pierce,  Fenner & Smith, Inc. ("Merrill Lynch") is not
          aware of any position,  office or directorship  relationship  with the
          company or its affiliates, however, Merrill Lynch may or may not have,
          from time to time, acted in a financial  investment  advisory capacity
          to the company or its affiliates.
