 with the amended termination provision.

The proposed amendment to Section 4(a)(iv) clarifies that a Business Combination is not subject to the Stockholders Agreement’s right of first refusal. This clarification ensures that the transfer restrictions in the agreement do not apply to the merger and is intended to eliminate any ambiguity regarding compliance with the agreement in connection with the transaction.

Taken together, these amendments are narrowly tailored, transaction-specific, and in the best interests of Bancorp Financial and its stockholders, as they help facilitate the closing of a merger that the Bancorp Financial board of directors has determined to be in the best interests of Bancorp Financial and its stockholders.

#### Recommendation of the Board
**The Board of Directors of Bancorp Financial unanimously recommends that stockholders vote “FOR” the proposed amendments to the Stockholders Agreement.**

#### Proposal 3 — Adjournment Proposal
**The Bancorp Financial special meeting may be adjourned or postponed to another time or place if a quorum is not present or if there are not sufficient votes to approve Proposal 1 (the merger proposal), and Proposal 2 (the stockholders agreement amendment proposal).

If approved, the proxy holders designated by the Bancorp Financial board of directors would be authorized to adjourn or postponed the meeting to a later date and time, without the need for further notice (unless required by Delaware law or Bancorp Financial’s bylaws), and to use the additional time to solicit additional proxies, including from stockholders who have previously voted against the merger proposal.

The Bancorp Financial board of directors unanimously recommends that Bancorp Financial stockholders vote “FOR” approval of the Bancorp Financial adjournment proposal.**
