As most recently described in our current report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) on January 30, 2007, the Board of Directors of Insight Enterprises, Inc. (the “Company”) has appointed an Options Subcommittee, composed of independent directors, to conduct a review of the Company’s historical stock option practices. As previously disclosed, the Options Subcommittee has retained independent outside legal counsel and accountants and is in the process of performing its review but has not reached any conclusions about the Company’s stock option practices. Also, on October 27, 2006, the Company received an informal inquiry from the SEC requesting certain documents and information relating to the Company’s stock option practices from January 1, 1996 to the present, and the Company is cooperating with the SEC in the informal inquiry. Additionally, certain present and former directors and executive officers of the Company were named as defendants in a derivative lawsuit related to stock option practices from 1997 to 2002, and the Company was named as a nominal defendant in that action. On January 19, 2007, the Court, at the plaintiff’s request, dismissed the lawsuit without prejudice. Also as previously disclosed, the Nasdaq Listing Qualifications Panel granted the Company’s request for continued listing on The Nasdaq Stock Market on the condition that the Company provide Nasdaq with certain information on or before the dates specified by Nasdaq and file its Form 10-Q for the third quarter ended September 30, 2006 on or before April 26, 2007.

The Company plans to file its Annual Report on Form 10-K for the year ended December 31, 2006 as soon as practicable, but does not expect that it will be filed on or before the fifteenth calendar day following the required filing date as prescribed in Rule 12b-25.
