This sale is mandated by the Issuer's election under its equity incentive plans to require the reporting person to fund this tax withholding obligation by completing a "sell to cover" transaction with a brokerage firm designated by the Issuer. This sale does not represent a discretionary trade by the reporting person. The reporting person previously reported the restricted stock units granted to the reporting person on April 9, 2014 in Table I of the Form 4/A filed on May 27, 2014. As such, no adjustment to the reporting persons beneficial interest needs to be made to reflect the vesting event on December 31, 2015. Robert W. Hesslein, as Attorney-in-Fact for Steven J.
