Julia B. North was appointed to our Board of Directors in December 2004 and serves as our Lead Director. She is presently retired. Over the course of her career, Ms. North has served in many senior executive positions, including as President of Consumer Services for BellSouth Telecommunications, Inc. from 1994 to 1997. After leaving BellSouth in 1997, she served as the President and Chief Executive Officer of VSI Enterprises, Inc., a manufacturer of video conferencing systems, until 1999. She currently serves on the board of directors of Acuity Brands, Inc., a provider of lighting fixtures and related products and services, and serves on its compensation committee and governance committee, with previous service on its audit committee. Ms. North also previously served on the boards of directors of Lumos Networks Corp., a fiber-based telecommunications service provider, where she also served on its compensation committee (chair); NTELOS Holdings Corp., a provider of wireless and wireline communications services, where she served on its compensation committee and nominating and governance committee (chair); Simtrol, Inc., a developer of enterprise-class software solutions, where she also served on its audit committee and compensation committee; Winn-Dixie Stores, Inc., a food retailer, where she also served on its compensation committee (chair), nominating and governance committee (chair), and audit committee; and MAPICS, Inc., a business application software and consulting company, where she also served on its compensation committee.

Ms. North has extensive experience serving on boards of directors and brings those experiences to her service on our Board’s Compensation Committee and Governance and Nominating Committee. The breadth of the industries in which she has worked provides risk assessment perspectives that are different from our operations. Her operational experience in customer service, marketing, technical network design, and strategic planning bring those skill sets, not represented by other Board members, to our Board’s functions.
