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) On January 20, 2012, the Reporting Person was granted 45,000 (target) performance-based restricted stock units ("PBRSUs") pursuant to the Issuer's 2006 Long-Term Incentive Plan. The PBRSUs were subject to both a time-based and a performance condition, and the actual award could be as low as zero and as high as 150% of target depending on the level of performance achieved. On January 19, 2015, the Compensation Committee determined that the level of performance achieved entitled the holders of the PBRSUs to 150% of their target award. Accordingly, on January 19, 2015, the PBRSUs' performance criteria vested, and the PBRSUs converted into the number of restricted stock units indicated on this Form 4. 50% of the restricted stock unit vests on each of the third and fourth anniversaries of the date of grant.
(2) On January 20, 2015, 50% of the restricted stock units described in Footnote 1 vested. The Reporting Person was required by the Issuer to defer the receipt of these shares pursuant to an existing deferral agreement. Provided that the Reporting Person remains employed by the Issuer, the remaining 50% of the restricted stock units described in Footnote 1 will vest on January 20, 2016.
(3) Transaction reported to show the change from direct to indirect ownership.

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