 meeting are announced at the original meeting, no further notice of the adjourned meeting is required unless the meeting is adjourned for more than 30 days or a new record date is fixed. In such cases, notice of the adjourned meeting must be given to each stockholder of record entitled to vote at the meeting. At any adjourned meeting, all proxies will be voted in the same manner as they would have been at the original meeting, unless they have been effectively revoked or withdrawn before the adjourned meeting.

#### Broker Non-Votes
A broker non-vote occurs when a bank, broker or other nominee submits a proxy on behalf of a beneficial owner but is not permitted to vote on a “non-routine” matter because the beneficial owner has not provided voting instructions. Under applicable stock exchange rules, brokers do not have discretionary authority to vote on non-routine matters without instructions from the beneficial owner. It is expected that all proposals to be voted on at the Bancorp Financial special meeting will be “non-routine.” As a result, if you hold your shares in “street name” and do not provide voting instructions to your bank, broker or other nominee, your shares will not be voted on any proposal at the special meeting.

However, because a proxy submitted by your bank, broker or nominee still represents your shares for attendance purposes, any such broker non-votes will be counted as present for purposes of establishing a quorum, unless otherwise provided in Bancorp Financial’s governing documents.

If your bank, broker or other nominee holds your shares of Bancorp Financial common stock in “street name,” it is important that you provide voting instructions by following the instructions included with the proxy materials delivered to you.

Required Vote; Treatment of Abstentions and Failure to Vote

merger proposal :

•

Standard : Approval of the merger proposal requires the affirmative vote of the holders of a majority of the outstanding Bancorp Financial common stock entitled to vote on the proposal. Bancorp Financial stockholders must approve the merger proposal in order for the merger to occur. If Bancorp Financial stockholders fail to approve the merger proposal, the merger will not occur.

•

Effect of abstentions and broker non-votes : If you fail to vote, mark “ABSTAIN” on your proxy card or fail to instruct your bank, broker or other nominee how to vote with respect to the merger proposal, it will have the same effect as a vote “AGAINST” the proposal.
