        positions in sales before moving into operations.

"The foundation of these changes is our continuing dedication to better serve our customers," said Edwardson. "Jim Shanks has proven to be an outstanding leader in organizing his sales teams to provide superior, value-added service to our public sector customers and driving productive change within the sales organization. We expect Jim to apply his skills to the entire sales organization, especially in the areas of customer segmentation within the corporate sector."
