DEX ONE REALIGNS INTERACTIVE OPERATIONS

CARY, N.C., November 10, 2010 — Dex One Corporation (NYSE: DEXO) today announced it is realigning its interactive operations and will fully integrate Business.com (http://business.com) into Dex One. As a result, the company plans to phase out the standalone, national business-to-business sales and marketing operation and focus exclusively on the Dex One business.

“Three years ago, Dex One required an infusion of talent and technology assets to support the expansion of its digital portfolio. The purchase of Business.com enabled Dex One to build the DexKnows.com local search platform, create the DexNet distributed ad network, and develop a robust account and content management system,” said Alfred Mockett, chief executive officer of Dex One. “While the acquisition delivered on a number of fronts, the Business.com operations are no longer viable and are not a part of our long-term plans.”

Dex One will continue to manage the Business.com site and support existing customers through an extended transition period. Following this period, Dex One will continue to control all rights associated with the Business.com brand and URL. Business.com customers with questions can call 1-888-441-4466.

The Dex One interactive operations are based in Santa Monica, Calif., and are responsible for developing online and mobile solutions that distribute local business information to consumers.
