On April 12, 2012, the reporting person settled a prepaid variable contract originally entered into on April 12, 2010 through the delivery of 490,000 shares of the Issuer's common stock. At the initiation of the contract, the bank paid $2,452,383.37 to the reporting person. See also footnote 2. In accordance with the variable prepaid forward sale contract, when settled in shares the number of shares to be delivered to the bank at maturity depends on the market price per share at maturity, but may not exceed 490,000 shares. If the market price per share at maturity was equal to or less than the floor price of $7.0382 per share, the reporting person would deliver 490,000 shares to the bank. If the market price per share at maturity was greater than the floor price, the reporting person would deliver a fewer number of shares. The market price per share at maturity on April 12, 2012 was $5.82. Accordingly, the reporting person transferred 490,000 shares of the Issuer's common stock to the bank. Common stock held by the reporting person's wife. The reporting person disclaims beneficial ownership of these shares. Common stock held by trust for the benefit of the reporting person's child of which the reporting person is a trustee. The reporting person disclaims beneficial ownership of these shares. /s/ Conor Kilroy, Attorney-in-Fact 2012-04-16
