the legal owner of the securities covered by this statement.
Pursuant to investment advisory agreements with its advisory clients,

          This Schedule 13G is also being filed by Nicholas Limited
Edition, Inc., an open-end management investment company registered

retains the beneficial ownership right to vote shares purchased by
Nicholas Company, Inc. for its account.

          This Schedule 13G is also being filed by Albert O.

Director and majority shareholder of Nicholas Company, Inc., in which
capacity he exercises dispositive power over the securities reported
herein by the Nicholas Company, Inc. and Nicholas Limited Edition,
