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.

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 to our Board’s functions.
