On April 6, 2011, CDW Corporation (the “Company”) announced that, in connection with the previously announced cash tender offer by CDW LLC (“CDW”) and CDW Finance Corporation (“CDW Finance,” and together with CDW, the “Co-Issuers”) for up to $665,138,000 aggregate principal amount (the “Maximum Tender Amount”) of the Co-Issuers’ outstanding 11.00% Senior Exchange Notes due 2015 (the “Senior Cash Pay Notes”) and the Co-Issuers’ outstanding 11.50% / 12.25% Senior PIK Election Exchange Notes due 2015 (the “Senior PIK Election Notes,” and together with the Senior Cash Pay Notes, the “Senior Notes”), pursuant to the Co-Issuers’ Offer to Purchase and Consent Solicitation Statement, dated as of February 22, 2011 and as subsequently amended and supplemented (as amended and supplemented, the “Offer to Purchase”), the withdrawal rights provided to all holders of Senior Notes that validly tendered (and did not validly withdraw) their Senior Notes expired at 5:00 p.m., New York City time, on April 5, 2011 (the “Withdrawal Right Expiration Date”).

The Company also announced that, as of the Withdrawal Right Expiration Date, the amount of Senior Notes validly tendered (and not validly withdrawn) has exceeded the Maximum Tender Amount. Since Senior Notes may no longer be withdrawn (except in the limited circumstances described in the Offer to Purchase), the Company announced that it expects that only the Maximum Tender Amount will be accepted for purchase, and the validly tendered Senior Notes will be purchased on a pro rata basis. The cash tender offer remains scheduled to expire at 8:00 a.m., New York City time, on April 12, 2011.

A copy of the press release announcing the expiration of the withdrawal rights and the valid tender of Senior Notes in excess of the Maximum Tender Amount is attached as Exhibit 99.1 and is incorporated by reference herein.
