 (“SEC”) permits companies to send the enclosed “Notice” instead of a full printed set of proxy materials. The Notice provides instructions on how to view your company’s proxy materials, including the shareholders meeting credential request form (on the reverse side),vote online and request a full set of printed materials by mail. There are several advantages to your company sending a Notice instead of a full set of materials, including lowering your company’s costs and reducing the environmental impact from printing and mailing full sets of proxy materials. How do I view the proxy materials online? The URL for the proxy materials is available under the “Important Notice Regarding the Availability of Proxy Materials” section of the enclosed Notice. What if I prefer to receive a paper copy of the proxy materials? You can easily request a paper copy which will be mailed to you at no cost. Instructions on how to do so can be found in the “To request paper copies of the proxy materials” section of the enclosed Notice. Can I receive proxy materials for future meetings by e-mailrather than receive a Notice? Yes you can. Instructions on how can be found on the “Email” section of the enclosed Notice. For more information about the SEC’s Notice and Access Proxy Rules please visit: www.sec.gov/spotlight/proxymatters/e-proxy.shtml.
