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 common stock in equal installments of one-third of the original RSU grant on either (i) the annual vesting of the grant or (ii) upon the conclusion of such longer deferral period as the Reporting Person may elect in advance. In either occurrence, (i) or (ii), the RSUs automatically convert into shares of common stock on a one-for-one basis at no conversion cost to the Reporting Person.
(2) This Restricted Stock Units (RSUs) grant is issued pursuant to a provision of the issuer Management Stock Purchase Plan (MSPP) whereby certain executives may make an advance election to receive RSUs in lieu of a specified percentage or dollar amount of that executives' annual incentive cash bonus under the bonus plan applicable to the executive. The RSUs are issued in whole units at a 33% discount from 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 the RSUs convert into shares of common stock on a one-for-one basis unless the executive previously elected a longer deferral period.
(3) The options generally vest in equal annual installments of one-third of the original stock option grant over a three year period from award date. The options convert into shares of common stock on a one-for-one basis.

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