 to approve each proposal at the Bancorp Financial special meeting?

A:

merger proposal :

#### •

Standard : Approval of the merger proposal requires the affirmative vote of the holders of a majority of the outstanding shares of 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.

Bancorp Financial has consented to the amendment, and stockholder approval of this proposal will constitute the remaining consent necessary to effect the amendment and termination of the Stockholders Agreement. Termination of the Stockholders Agreement is a condition to closing the merger. If Bancorp Financial stockholders fail to approve the stockholders agreement amendment 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 stockholders agreement amendment proposal, it will have the same effect as a vote “AGAINST” the proposal because approval is based on the total number of outstanding shares.

adjournment proposal :

#### •

Standard : Approval of the adjournment proposal requires the affirmative vote of a majority of the shares present in person or represented by proxy at the meeting and entitled to vote on the proposal, provided a quorum is present. If a quorum is not present, the meeting may be adjourned by the affirmative vote of a majority of the shares present in person or represented by proxy. If Bancorp Financial stockholders fail to approve the adjournment proposal but approve the merger proposal and the stockholders agreement amendment proposal, the merger may nonetheless occur.

#### •

Effect of abstentions and broker non-votes : Because shares voted “ABSTAIN” are counted as present for purposes of determining
