Important Information about the Notice of Proxy Materials

This notice regarding the online availability of proxy materials (Notice) is provided to certain shareholders in place of the printed materials for the upcoming Annual Meeting of Shareholders.

In 2007, the Securities and Exchange Commission adopted a voluntary rule permitting Internet-based delivery of proxy materials. Companies can now send Notices, rather than printed proxy materials to shareholders. This will help lower mailing, printing and storage costs for the company, while minimizing environmental impact. This Notice contains specific information regarding the annual shareholder meeting, proposals to be considered at the meeting and the Internet site where the proxy materials may be found.
