Beneficial Owner: Shares Registered in the Name of Broker, Bank or Other Nominee If you are a beneficial owner of shares registered in the name of your broker, bank or other nominee, you should have received a WHITEvoting instruction formfrom that organization rather than from us. Simply follow the voting instructions to ensure that your vote is counted. Prior to the Annual Meeting, you will be able to vote by mail, via the Internet or by telephone. You may also obtain a “legal proxy” from your broker, bank or other nominee and register in advance to attend and vote at the Annual Meeting by following the instructions described below. Even if you wish to attend the Annual Meeting, we urge you to vote your shares in advance of the Annual Meeting by following the instructions on your WHITEvoting instruction form.

To ensure that all of your shares are represented at the Annual Meeting, we recommend that you submit every WHITEproxy card or WHITEvoting instruction form you receive.

Our Board recommends you vote “ FOR” the Board’s two nominees by submitting the enclosed WHITEproxy card. Even if you would like to elect one or both of the Mangless Nominees, we strongly recommend you use the Company’s WHITEproxy card to do so.
