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) The grant of Restricted Stock Units (RSUs), reported herein, entitles the reporting person to receive shares of the issuer's common stock on the later of (i) vesting of the grant or a portion thereof and (ii) such longer deferral period as the reporting person may have elected in advance.
(2) The Restricted Stock Units (RSUs), reported herein vest in equal installments of one-sixth per year on 3/28/08, 2/26/09, 2/26/10, 2/26/11, 2/26/12 and 2/26/13.
(3) As noted in footnotes 1 and 2, the Restricted Stock Units vest over a six-year period and, subject to any longer deferral period selected by the reporting person, automatically convert into shares of common stock at no conversion cost to the reporting person.
(4) Restricted Stock Units (RSUS) convert into shares of common stock on a one-for-one basis. These RSUs are issued pursuant to a provision under the issuer's Management Stock Purchase Plan (MSPP) pursuant to which certain executives may make an advance election to receive RSUs in lieu of a specified percentage or dollar amount of an individual's annual incentive cash bonus under bonus plan applicable to the executive. The RSUs are issed in whole units on the basis of a 33% discount from the fair market value of the issuer's common stock on the date the underlying bonus is determined and generally vest 3 years from the date of the grant, at which time they convert into shares of commons tock unless the executive has previously elected a longer deferral period.

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