Sale completes Interliant¦s divestiture of non-core businesses

PURCHASE, NEW YORK, JAN. 6, 2003 v Interliant, Inc. (OTCBB:INIT.OB), a leading provider of managed infrastructure solutions, today announced that it has completed the sale of its Oracle professional services business to SchlumbergerSema, a subsidiary of Schlumberger (NYSE:SLB) through an asset sale transaction. This sale completes the planned divestitures of non-core businesses which Interliant announced on August 5, 2002, when the company filed for reorganization under Chapter 11 of the U.S. Bankruptcy Code.

The sale of the assets of the Dallas, Texas-based consulting group was closed on December 20, 2002, for cash and the assumption by SchlumbergerSema of certain debt related to the Oracle business. Additionally, SchlumbergerSema has hired all of the employees of the business.

“We have now completed an important part of our restructuring,” said Francis J. Alfano, Interliant¦s president and CEO. “Now that we have divested our non-core businesses, we can focus all of our resources on the solution areas for which we see the greatest market demand and profit potential: our managed hosting, managed messaging, and bundled security offerings. With these sales complete, we believe we are well-positioned to move on to our next milestone: emergence from Chapter 11.”
