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 granted to the Reporting Person by the issuer as part of equity incentive grants made by the issuer on 3/5/12 utilizing a fair market value (FMV) of a share of the issuers stock of $32.76. 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 unless the Reporting Person has previously chosen a longer deferral period. The report reflects the vesting of the one-third portion of the original RSU grant and the acquisition by the Reporting Person of the common stock underlying the RSUs minus sufficient shares withheld by the issuer at the request of the Reporting Person as necessary 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.

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