 your appraisal rights, you must satisfy all of the following conditions:

1.

#### Written Demand
: Before the vote on the merger proposal at the Bancorp Financial special meeting, you must deliver to Bancorp Financial a written demand for appraisal of your shares. This written demand must reasonably inform Bancorp Financial of your identity and your intention to seek appraisal.

2.

#### No Vote in Favor
: You must not vote in favor of the merger proposal. Voting against the merger proposal or abstaining from voting will not, in and of itself, constitute a written demand for appraisal as required by Section 262. Similarly, failing to vote will not constitute a demand for appraisal rights.

3.

#### Continuous Ownership
: You must continuously hold your shares of Bancorp Financial common stock from the date of making the written demand through the effective date of the merger. Appraisal rights will be lost if you transfer your shares before the effective date of the merger.

#### Notification and Petition for Appraisal
Within ten (10) days after the effective date of the merger, the surviving corporation must notify each stockholder who has properly asserted appraisal rights and not voted in favor of the merger of the effective date. Within 120 days after the effective date, any stockholder who has complied with the required conditions may commence an appraisal proceeding by filing a petition in the Delaware Court of Chancery, demanding a determination of the fair value of the shares. If no petition is filed within this 120-day period, appraisal rights will be lost.

The court will determine which stockholders have properly exercised appraisal rights and are entitled to appraisal, and will then appraise the shares’ fair value, exclusive of any element of value arising from the accomplishment or expectation of the merger. The court may also determine and assess costs of the proceeding as it deems equitable.

#### Important Considerations
•

Waiver of Rights: Failing to comply strictly with the procedures set forth in Section 262 of the DGCL will result in the loss of appraisal rights.

•

Judicial Determination: The Delaware Court of Chancery will determine the fair value of your shares, which may result in a value that is higher, lower, or the same as the merger consideration.
