Explanation of Responses:
( 1)	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 3/4/2013 utilizing a fair market value (FMV) of a share of the issuers stock of $42.12. 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 minus sufficient shares withheld to pay applicable income taxes.
( 2)	The shares reported as indirectly held by the reporting person are held in a revocable trust for which the reporting person and his spouse serve as both trustees and beneficiaries; as such, the total number of shares held indirectly also reflects the previous transfer of shares from the reporting person to such trust, a transaction which is exempt from the reporting requirements of Section 16 as such transaction had no effect on the reporting person's pecuniary interest in the underlying shares.
( 3)	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 3/4/2013 utilizing a fair market value (FMV) of a share of the issuers stock of $42.12. 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 ios determined ($28.22 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 minus sufficient shares withheld to pay applicable income taxes.
( 4)	The shares issued herein to the Reporting Person by the issuer are the result of actual achievement against the metrics associated with a Performance Based RSU grant made by the issuer on 3/4/2013. These metrics consisted of targets for 2015 Return on Invested Capital and Adjusted Operating Margin with potential payouts ranging from 0% to 200%. This report reflects the acquisition of shares by the Reporting Person based on 90% achievement minus sufficient shares withheld to pay applicable income taxes.
( 5)	The reported price reflects an average price with a trading range of high of $42.71 and a low of $42.59. The reporting person will provide details regarding the sales to the issuer, the Securities and Exchange Commission or any shareholder upon request.
