Questions & Answers

Why am I receiving this Notice of Internet Availability?

What is the easiest way to vote my shares?

Why did I receive this Notice of Internet Availability (Notice) and not the printed proxy materials?

In 2007, the SEC adopted new Notice and Access Rules. Companies are now permitted to send the enclosed Notice instead of a full printed set of proxy materials. The Notice gives you instructions on how to view your company’s proxy materials and vote online or how to receive 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:

Increases shareholder value and lowers your company’s printing and mailing costs.

Reduces environmental impact - saves trees and reduces fossil fuel consumption.

Allows faster notification of how to access materials in an easily searchable format.

How do I view the proxy materials online?

Go to www.ProxyVote.com and follow the instructions to view the materials. It is necessary to provide the information printed

in the box marked by the arrow 1234 5678 9042 located on the Notice.

What if I still prefer to receive a paper copy of the proxy materials?

You can easily request a paper copy at no cost, you will need the information on the Notice that is printed in the box marked by the arrow 1234 5678 9042 and select from one of the three options below.
