Important Information about the Notice of Proxy Materials

This Notice Regarding the Online Availability of Proxy Materials (Notice) is provided to shareholders in place of the printed materials for the upcoming Shareholder Meeting.

Information about the Notice:

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 may help lower mailing, printing and storage costs for the company, while minimizing environmental impact. This Notice contains specific information regarding the meeting, proposals and the internet site where the proxy materials may be found.

To view the proxy materials online:

Please refer to the instructions in this Notice on how to access and view the proxy materials online, including the proxy card, annual report and proxy statement.

To receive paper copies of the proxy materials:

Please refer to the instructions in this Notice on how to request hard copies of proxy materials via phone, email or Internet.
