 Chairman because of his detailed and in-depthknowledge of the issues, opportunities and challenges facing the Company, his familiarity with the Company’s business and industry, and his ability to identify strategic priorities essential to the future success of the Company. The Board believes that this structure is best for the Company because it provides for clear leadership responsibility and accountability, while providing for effective corporate governance and oversight by an independent Board of strong and seasoned Directors with an independent Lead Director. Mr. Singleton serves as the Board’s independent Lead Director and presides over executive sessions of the Board. The non-managementmembers of our Board meet in executive session at each regularly scheduled Board meeting. The Audit, Compensation, and Nominating and Governance Committees are all chaired by and composed solely of independent Directors in accordance with independence standards of the NYSE, and thus oversight of key matters is entrusted to the independent Directors. Each of these Committees also meets in executive session without members of management present. The responsibilities of the Lead Director include the following:

| • |     | Presides at all meetings of the Board at which the Chairman is not present, including meetings of independent Directors held in executive session; |

| • |     | Has the authority to call meetings of the independent Directors; |

| • |     | Leads the Board evaluation program; |

| • |     | Evaluates, along with the members of the Compensation Committee and the full Board, the CEO’s performance, and meets with the CEO to discuss the Board’s evaluation; |

| • |     | Serves as a liaison between the Chairman/CEO and the independent Directors; |

| • |     | Consults with the Chairman/CEO on and approves agendas and schedules for Board meetings to ensure there is sufficient time for discussion of agenda items; |

| • |     | Advises the Chairman/CEO on the Board’s informational requirements and approves information sent to the Board, as appropriate; |

| • |     | Consults with the Chair of the Nominating and Governance Committee and the Chairman regarding recommended appointments of Committee members, including Committee chairs; and |

| • |     | Facilitates communication between the Board and senior management. |

The Lead Director assures that appropriate independence is brought to bear on important Board and governance matters. In addition, there is strong leadership vested in and exercised by the independent Committee chairs, and each Director may request inclusion of specific items on the agendas for Board and Committee meetings. Considering all of the above, the Board believes that a combined Chairman and Chief Executive Officer, together with the Lead Director, is
