One or more of Nicholas Company, Inc.'s advisory clients is the legal owner of the securities covered by this statement. Pursuant to investment advisory agreements with its advisory clients, Nicholas Company, Inc. has the authority to direct the investments of its advisory clients, and consequently to authorize the disposition of the Issuer's shares.

This Schedule 13G is also being filed by Nicholas Fund, Inc., an open-end management investment company registered under the Investment Company Act of 1940. Nicholas Company, Inc. acts as the investment adviser to Nicholas Fund, Inc., and as such retains dispositive control of the shares in which Nicholas Fund, Inc. invests.

This Schedule 13G is also being filed by Albert O. Nicholas. Mr. Nicholas is the Chief Executive Officer, Chairman, a 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 Fund, Inc.
