Dear Shareholders,
Enclosed please find a revised Proxy Card. The previous Proxy Card incorrectly listed two directors who were re-elected last year, Kathryn L. Munro and Larry A. Kring. The Proxy Card has been revised to list Richard P. Fox and Lorenzo C. Lamadrid as the nominees to serve 3-year terms as directors, as was correctly listed and discussed in the Proxy Statement. We apologize for any convenience.
John S. Leness
