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 Restricted Stock Units (RSUs), the conversion of which are reported herein, were issued to the Reporting Person pursuant to issuers Management Stock Purchase Plan (MSPP) on 3/3/2014 utilizing a fair market value (FMV) of a share of the issuers stock of $71.56. RSUs are issued in whole units on the basis of a 33 percent discount from FMV of the issuers common stock on the date the underlying bonus is determined ($47.95 in this case) and generally vest 3 years from date of grant, at which time they convert into shares of common stock unless the executive has previously elected a longer deferral period. Acquisition price reflects the 33% discount to FMV of issuers stock on grant date. This report reflects the acquisition by the Reporting Person of the common stock underlying the RSUs.
(2) The Restricted Stock Units (RSUs), the conversion of which are reported herein, were granted to the Reporting Person by the issuer as part of equity incentive grants made by the issuer on 3/03/2014 utilizing a fair market value (FMV) of a share of the issuers stock of $71.56. The RSU grant vests in equal portions over a three year period, and are received by the Reporting Person upon vesting, on a one-for-one basis. This report reflects the final vesting of one-third portion of the original RSU grant and the acquisition by the Reporting Person of the underlying shares.
