Explanation of Responses:

1. Represents acquisition of equivalent shares of the Issuer's common stock through the Issuer's Stock Deferred Compensation Plan.

2. Represents approximate equivalent number of shares of the Issuer's common stock held in the reporting person's account under the Issuer's Stock Deferred Compensation Plan, based on the most recent plan account statement. The approximate equivalent number of shares is equal to the dollar value of the reporting person's plan account divided by the closing price of the Issuer's common stock. As a result, the equivalent number of shares will fluctuate with changes in the market price of the Issuer's common stock.

3. Received in the Merger in exchange for director stock units (representing deferred director fees) ('DSUs") for 6,055 shares of FOBB common stock.

4. Amount reflects additional Director Stock Units credited to the Reporting Person based on the cash dividend paid to all stockholders of the Issuer subsequent to the last Form 4 filed by the Reporting Person.
