If you return your BLUE proxy card by mail, please ensure you leave enough time for your BLUE proxy card to be mailed and received. You are encouraged to sign, date and return the BLUE proxy card in the postage-paid envelope provided (or vote by Internet or by telephone) regardless of whether you plan to attend the Annual Meeting. Beneficial Owners If you are the beneficial owner of your shares (that is, you hold your shares in “street name” through an intermediary such as a bank, broker or other nominee), you will receive instructions from your bank, broker or other nominee as to how to vote your shares or submit a proxy to have your shares voted. Your bank, broker or other nominee may not be able to vote your shares on any matters at the annual meeting unless you provide them instructions on how to vote your shares. You should instruct your bank, broker or other nominee how to vote your shares by following the directions provided by your bank, broker or other nominee. Alternatively, you may obtain a “legal proxy” from your bank, broker or other nominee and bring it with you to hand in with a ballot in order to be able to vote your shares at the annual meeting. If you choose to vote at the annual meeting, you must bring proof of identification and a signed “legal proxy” from the shareholder of record (your bank, broker or other nominee) giving you the right to vote the shares. Please follow the instructions provided by your bank, broker or other nominee. If you return your BLUE voting instruction form by mail, please ensure you leave enough time for your BLUE voting instruction form to be received by the deadline provided by your bank, broker or other nominee.
