Insight Public Sector Completes a Release and Settlement Agreement with the U.S. Department of Justice.

TEMPE, Ariz. -- Insight Enterprises Inc. (Nasdaq: NSIT) (the "company") today announced that its subsidiary, Insight Public Sector, has reached a release and settlement agreement with the U.S. Department of Justice (the "DOJ") regarding an investigation of the size representation made by Comark Government & Education Services Inc. ("CGES") in March 1996. The company acquired CGES as part of its April 2002 acquisition of Comark Inc.

In response to a 1995 solicitation issued by the General Services Administration ("GSA") to participate in the GSA's Multiple Award Schedule ("MAS"), CGES represented, in March 1996, that it was a small business. GSA awarded an MAS contract to CGES, and that contract remains in place, although Insight Public Sector (as CGES is now known) stopped representing itself as small under the GSA MAS contract in May 2004. The DOJ, in conjunction with the U.S. Small Business Administration ("SBA") and the GSA, contended, following an SBA investigation, that CGES was not small as represented in March 1996 and, accordingly, that it had obtained a preference in the award of some purchase orders under the MAS as a result of its small size representation. Insight Public Sector disputed the government's claims but has agreed to settle the matter. The release and settlement includes no admission of wrongdoing or fault by Insight Public Sector and is not expected to materially affect the on-going operations of Insight Public Sector.

As part of the release and settlement, Insight Public Sector will pay the United States $1 million to resolve DOJ, GSA and SBA claims related to the small size representation of CGES. Although the settlement relates to periods prior to the acquisition of Comark in April 2002, the $1 million settlement will be recorded as an expense in Q1 2006 as, in accordance with generally accepted accounting principles ("GAAP"), too much time has passed since the acquisition to adjust goodwill. The company will exclude this amount when disclosing its non-GAAP financial measures in its earnings release.

"Although we remain convinced that the company did not have a liability to the federal government as a result of the small size representation of CGES in March 1996, we agreed to settle the matter to avoid the risk, expense and internal diversion of litigation," said Richard Fennessy, president and chief executive officer. "We have worked cooperatively with the DOJ, GSA and SBA on this matter, and the company is pleased to have resolved this matter."
