 submit a proxy as soon as possible so that your shares can be voted at the meeting in accordance with your instructions. You may submit your proxy (1) through the Internet or (2) by completing, signing, dating and returning the proxy card in the enclosed postage-paid envelope by mail. For specific instructions, please refer to the accompanying proxy card. Any stockholder present at the annual meeting may revoke his or her proxy and vote personally on each matter brought before the annual meeting. However, if you are a stockholder whose shares are not registered in your own name, you will need additional documentation from your record holder in order to vote in person at the annual meeting. Attendance at the annual meeting will not in itself constitute revocation of your proxy.

We also are soliciting voting instructions from participants in the North Shore Trust and Savings Employee Stock Ownership Plan (“ESOP”) who may direct the ESOP trustee to vote shares on their behalf under the ESOP. We ask each plan participant to sign, date and return the voting instruction card or provide voting instructions through the Internet as described on the Notice and the voting instruction card.
