Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) These transactions were omitted from the reporting person's original Form 4, which included the amounts representing the reporting person's tax withholding, but not the conversion from restricted stock units to restricted stock. The reporting person received the restricted stock units referenced on April 28, 2011, which represented the maximum expected award available to the reporting person under the issuer's 2011 executive incentive compensation policy. The actual stock-based incentive amounts earned by the reporting person was determined by the issuer's compensation committee on March 16, 2012 and the referenced transactions represent the settlement of the restricted stock unit in shares and the forfeiture of the remaining unearned restricted stock units.
(2) On March 16, 2012, the issuer's compensation committee settled the referenced short-term and long-term performance-based stock bonuses for fiscal 2011 based on the closing price of $23.16 for the issuer's common stock on March 16, 2012.
(3) The total number of shares beneficially owned includes the effects of the tax withholdings previously referenced on the reporting person's original Form 4 with respect to shares directly beneficially owned.
(4) This transaction represents the unvested long-term bonus award paid to the reporting person. 9,015 shares shall vest annually beginning on March 16, 2013 and on the same date of each year thereafter until the full amount of the award is vested, subject to the reporting person's continued employment through each of the vesting dates.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.

Potential persons who are to respond to the collection of information contained in this form are not required to respond unless the form displays a currently valid OMB number.
