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)	Shares are allocated to the Reporting Persons account in The Employee Stock Ownership Plan of Issuer. The acquisition is exempt pursuant to Rule 16b-3(c).
(2)	The acquisition is of Restricted Stock Units (RSUs) granted automatically on March 15, 2013 (the payment date for a dividend on Issuer common stock). The new RSUs were granted as dividend equivalents (DE RSUs) pursuant to the terms and conditions of the applicable RSU award agreements. The Reporting Person received the DE RSUs in connection with the following previously reported RSUs that were unvested on the February 19, 2013 dividend record date but vested on March 8, 2013 (prior to the dividend payment date): (i) performance-vesting RSUs granted February 23, 2010, February 24, 2011 and December 1, 2011; (ii) a 30% tranche of time-vesting RSUs granted February 24, 2011; and (iii) DE RSUs previously received in connection with such underlying RSUs. The DE RSUs reported in this row vested on the date they were issued (March 15, 2013). The vesting created taxable income subject to tax withholding in shares as described in note (4).
(3)	On the dividend payment date, the Reporting Person received additional DE RSUs in connection with the unvested portion (50%) of previously reported time-vesting RSUs granted on February 24, 2011 (as well as on DE RSUs previously issued on such underlying RSUs). The new DE RSUs are subject to the same vesting terms and conditions as the underlying RSUs, as shown in a previous Section 16 filing.
(4)	The Compensation Committee of the Issuers Board of Directors allows the withholding of shares (Tax Withholding Transactions) to satisfy the Reporting Persons income tax obligation from an RSU vesting. The Committee pre-approves, at the time of grant, the Reporting Persons Tax Withholding Transactions for RSUs. This form reports the number of shares retained for the Tax Withholding Transactions in connection with the DE RSU vesting described in note (2) and in connection with the March 15, 2013 vesting of certain other previously reported DE RSUs.

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