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) Acquisition upon satisfaction of performance condition applicable to performance-based restricted stock units. On October 19, 2010, the Compensation Committee of the Board of Directors of the Issuer (the "Committee") approved the grant of a Restricted Stock Unit Agreement (the "RSU Agreement") to the Reporting Person. The RSU Agreement covers 183,418 shares and provides for vesting in two installments, contingent on the Company having at least $125 million of adjusted net income during either fiscal 2011 or fiscal 2012 (the "Performance Condition") and the Reporting Person satisfying the service conditions of the RSU Agreement. On October 21, 2011, the Committee certified that the Performance Condition had been satisfied.
(2) Two-thirds of the restricted stock units will vest if: (i) the Reporting Person continues to serve as Chief Executive Officer through December 31, 2012, as such date may be accelerated or extended by the Board of Directors of the Issuer (the "Board"), provided that such date may not be extended beyond December 31, 2013 (such date, as accelerated or extended, the "Succession Date"); (ii) the Reporting Person serves as interim Chief Executive Officer at the request of the Board at any time during the two-year period commencing on the Succession Date (the "Transition Period") in the event that the Reporting Person's successor is no longer serving as Chief Executive Officer for any reason; and (iii) the Reporting Person serves as Vice Chairman of the Board for a period commencing on the Succession Date through the earlier of (A) the two-year anniversary of the Succession Date and (B) the date the Reporting Person fails to be nominated, appointed, or re-elected to the Board through no fault of the Reporting Person. The remaining one-third of the restricted stock units will vest if the Reporting Person satisfies the aforementioned service conditions and continues to serve as Vice Chairman of the Board for an additional period of two years thereafter. Subject to certain exceptions in the case of the death or disability of the Reporting Person or a change in control of the Issuer, no portion of the restricted stock units will vest prior to the end of the Transition Period.
(3) Represents dividend equivalent units ("DEUs") accrued on restricted stock units granted to the Reporting Person under the Issuer's 2005 Omnibus Incentive Plan. DEUs are settled in shares of the Issuer's Class A Common Stock upon the vesting of the underlying restricted stock units.
(4) These shares are held in trust for the benefit of the Reporting Person's children.
