Electronic Delivery of Shareholder Communications

SST is pleased to offer its shareholders the opportunity to receive shareholder material electronically with the added advantage of voting your shares online. By signing up for electronic delivery of shareholder material, such as the Annual Report and Proxy Statement, you will receive notice via e-mail as soon as the shareholder material becomes available online. Furthermore, you will no longer need to wait to receive shareholder material by mail. There are other benefits to signing up.
