This Form 4 amends the Form 4 filed by the reporting person on May 19, 2015 to reflect the cancellation and re-booking of the sale to effect the sale of the correct number of shares to cover the reporting person's tax liability incurred upon the vesting of the reporting person's restricted shares. The broker had inadvertently oversold the number of shares required to cover the reporting person's tax liability by 1,643. The price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions at prices ranging from $16.69 to $17.76, inclusive.
