Westwood, Mass.--December 9, 2002--Centerstone Software, a pioneer in Workplace Resource Management, today announced that AOL Time Warner Book Group has signed a contract agreement for its e-Center One solution. The company initially implemented the technology in a pilot program to manage a move of 90 positions within their Boston office. AOL Time Warner Book Group is now implementing e-Center One to manage their Boston, New York, and Indiana workplaces.

"We anticipate that e-Center One will become a valuable and strategic planning tool," says Judith Graham, director of corporate operations for AOL Time Warner Book Group. "The software allows us to propose various scenarios and make sound decisions on where to place departments and employees for maximum efficiencies. In addition, we look forward to making the Corporate Mapping* feature of e-Center One available on our intranet site."

e-Center One is a Web-based solution that allows companies to make accurate decisions on how to best use their facilities and resources by tying together multiple databases and software products throughout the workplace, providing a holistic view of an organization's real estate, facilities, space, operations, personnel, life safety and asset information. Its Corporate Mapping functionality allows employees to view floor plans, seating charts, phone extensions, evacuation routes, room reservations and other general employee information.

"e-Center One provides immediate value to our customers,", says Matthew Meyer, founder and chief strategy officer for Centerstone Software. "By working hand-in-hand with AOL Time Warner Book Group, we were able to execute a move that was smooth, cost effective and quick. AOL Time Warner Book Group will be using e-Center one to make strategic workplace decisions. We are certain they will continue to see measurable benefit from the technology, and we look forward to aiding in their continued success."
