On March 7, 2011, CDW Corporation announced that, in connection with the previously announced cash tender offer and consent solicitation by its wholly owned subsidiaries, CDW LLC and CDW Finance Corporation (collectively, the “Issuers”), for all of the Issuers’ outstanding $890,000,000 aggregate principal amount of 11.00% Senior Exchange Notes due 2015 (the “Senior Cash Pay Notes”) and all of their outstanding $316,974,000 aggregate principal amount of 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 Issuers’ Offer to Purchase and Consent Solicitation Statement, dated as of February 22, 2011 (as amended or supplemented, the “Offer to Purchase”), the Issuers have received the requisite consents to adopt proposed amendments to the indenture governing the Senior Notes (the “Indenture”) that would, among other things, eliminate substantially all of the restrictive covenants and certain events of default contained in the Indenture.

As of 5:00 p.m., New York City time, on March 7, 2011, holders of $759,207,000 of the Senior Cash Pay Notes and $217,569,859 of the Senior PIK Election Notes, together representing approximately 80.93% of the Senior Notes, had tendered their Senior Notes in the tender offer and consented to the proposed amendments to the Indenture.

Upon receiving the requisite consents, the Issuers, the applicable guarantors and U.S. Bank National Association, as trustee, executed a supplemental indenture with respect to the Indenture implementing the proposed amendments described above. The supplemental indenture became effective upon execution, but the amendments to the Indenture will not become operative until acceptance of the Senior Notes by the Issuers pursuant to the terms and conditions described in the Offer to Purchase. A copy of the supplemental indenture is attached hereto as Exhibit 4.1 and is incorporated by reference herein.

On March 7, 2011, CDW Corporation issued a press release relating to the Issuers’ receipt of requisite consents pursuant to the tender offer and consent solicitation and acceleration of the expiration time of the tender offer. A copy of the press release is attached hereto as Exhibit 99.1 and is incorporated by reference herein.
