Purchase Agreement

On December 3, 2010, CDW LLC (“CDW”) and CDW Finance Corporation (together with CDW, the “Issuers”) entered into a purchase agreement (the “Purchase Agreement”) among the Issuers, the guarantors named therein and the initial purchasers named therein (the “Initial Purchasers”). Pursuant to the Purchase Agreement, the Initial Purchasers have agreed to purchase from the Issuers $450 million aggregate principal amount of 8% senior secured notes due 2018 (subject to an option (the “over-allotment option”) of the Initial Purchasers to purchase up to an additional $50 million in aggregate principal amount of notes). The Purchase Agreement contains customary representations and warranties of the parties and indemnification and contribution provisions whereby the Issuers and the guarantors, on the one hand, and the Initial Purchasers, on the other hand, have agreed to indemnify each other against certain liabilities. The sale of the notes is expected to close on December 17, 2010, subject to certain closing conditions.

Credit Facility Amendment

On December 2, 2010, CDW entered into an amendment to its term loan agreement among CDW, CDW Corporation, the guarantors named therein, Morgan Stanley Senior Funding, Inc., as administrative agent, Morgan Stanley & Co. Incorporated and the lenders named therein (the “Term Loan Amendment”). The Term Loan Amendment, among other things, (i) extends the maturity of $1.162 billion in term loans (assuming no exercise of the over-allotment option) held by accepting lenders from October 10, 2014 to July 15, 2017, (ii) increases the interest rate with respect to such extended-maturity term loans by 100 basis points and (iii) allows for the issuance of the senior secured notes at closing and for the issuance of additional senior secured indebtedness on a pari passu basis with the term loans in the future (subject to meeting certain incurrence tests at such time). The Term Loan Amendment is expected to become effective on December 17, 2010, subject to certain conditions.

The description of the amendment contained in this Current Report on Form 8-K is qualified in its entirety by reference to the complete text of the amendment, a copy of which is filed herewith as Exhibit 10.1, which is incorporated herein by reference.

In connection with the execution of the Purchase Agreement, the Issuers, which are wholly owned subsidiaries of CDW Corporation, priced the previously announced private offering of their senior secured notes. The offering consists of $450 million principal amount (subject to increase under the over-allotment option) of the Issuers’ 8% senior secured notes due 2018. The sale of the notes is expected to close on December 17, 2010, subject to certain closing conditions. All of the proceeds from the offering will be used to repay indebtedness outstanding under CDW’s senior secured term loan at par.

This Form 8-K does not constitute an offer to sell or the solicitation of an offer to buy these securities, nor shall there be any offer, solicitation or sale of these securities in any state in which such offer, solicitation or sale would be unlawful. These securities have not been registered under the Securities Act of 1933 or any state securities laws and, unless so registered, may not be offered or sold in the United States except pursuant to an exemption from the registration requirements of the Securities Act of 1933 and applicable state laws.
