#### Quorum and Adjournment
A quorum is the number of shares that must be present, in person or by proxy, in order for business to be transacted at the Bancorp Financial special meeting. Holders representing a majority of the outstanding shares of Bancorp Financial common stock entitled to vote at the meeting, present in person or by proxy, constitute a quorum. All shares represented at the meeting, including shares voting to abstain and broker non-votes (if any), will be counted as present for purposes of determining whether a quorum is present.

If a quorum is not present at the Bancorp Financial special meeting, or if the number of shares present in person or by proxy and voting in favor of the merger proposal or the stockholders agreement amendment proposal is insufficient to approve either proposal, the holders of a majority of the shares present in person or by proxy at the meeting may adjourn the meeting to a later date or time to permit the solicitation of additional proxies. In that event, stockholders may be asked to vote only on the adjournment proposal. 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.
