***IMPORTANT REMINDER: PLEASE VOTE TODAY***

Dear Stockholder:

We have previously mailed you information relative to the Special Meeting of Stockholders of Rockville Financial, Inc. to be held on April 8, 2014.

According to our latest records we have not yet received your vote. The Special Meeting is now only a short time away. It is important that you sign and return the enclosed proxy card today in order to make sure that your shares will be voted at the meeting in accordance with your desires.

Your Board of Directors recommends that you vote FOR proposals 1, 2, 3 and 4.

The approval of the Rockville merger proposal requires the affirmative vote of at least two-thirds of the outstanding shares. The approval of the amendment to Rockville’s certificate of incorporation requires the affirmative vote of not less than 80% of the outstanding shares of Rockville common stock.

 

Your vote is very important no matter how many shares you own.

If you fail to vote or mark “ABSTAIN” on your proxy with respect to the Rockville merger proposal or the Rockville certificate amendment proposal, it will have the same effect as a vote “AGAINST” the proposals.

Please sign and date the enclosed proxy card today. In the event that more than one vote is received from you, the one bearing the latest date will be counted, as it automatically revokes all prior proxies.

Thank you for your cooperation and continued support.

Sincerely,

William H. W. Crawford, IV
