SHARE REPURCHASE AGREEMENT

THIS SHARE REPURCHASE AGREEMENT (this “Agreement”) is entered into as of May 17, 2015 by and among CDW Corporation, a Delaware corporation (the “Company”), and each of the entities identified on Schedule 1 hereto (each, a “Seller,” and collectively, the “Sellers”).

Background

A. The Sellers own in aggregate 50,277,151 shares of the Company’s common stock, par value $0.01 per share (the “Common Shares”), and propose to sell a portion of the Common Shares owned by the Sellers to the Company on the terms and conditions set forth in this Agreement;

B. The Company proposes to repurchase from the Sellers up to 3,000,000 Common Shares in aggregate, with the definitive number of repurchase shares to be mutually agreed between the Company and the Sellers prior to the commencement of the Public Offering (the “Repurchase Shares”), at the price and upon the terms and conditions provided in this Agreement (the “Repurchase”);

C. Promptly after the date hereof, the Sellers, collectively with certain other shareholders of the Company, intend to commence an underwritten public offering (the “Public Offering”) of Common Shares held by the Sellers and such other shareholders (the “Underwritten Shares”);

D. The board of directors of the Company (the “Board”) has authorized a program pursuant to which the Company may repurchase Common Shares, having an aggregate value of up to $500.0 million, from time to time in the open market or in privately negotiated transactions (the “Repurchase Program”); and

F. The Audit Committee of the Board has reviewed and approved the related party transaction involving the Repurchase and related transactions that may be required in connection with the Repurchase pursuant to the requirements of the Company’s Related Party Transaction Review/Approval Procedures.

THEREFORE, in consideration of the mutual covenants herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned hereby agree as follows:

Agreement

1. Repurchase.

(a) At the Closing (as defined below), subject to the satisfaction of the conditions and to the terms set forth in paragraph 1(b), each Seller, severally and not jointly, agrees to transfer, assign, sell, convey and deliver a number of Common Shares equal to such Seller’s pro rata portion of the Repurchase Shares as set forth opposite such Seller’s name on Schedule 1, to the Company, and the Company hereby agrees to purchase such Repurchase

Shares from such Seller at the per share price at which the Sellers sell the Underwritten Shares to the underwriters in the Public Offering (the “Per Share Purchase Price”); provided that, the number of shares to be sold by each Seller shall be equitably adjusted to avoid fractional shares.

(b) The obligations of the Company to purchase the Repurchase Shares shall be subject to the closing of the Public Offering pursuant to an underwriting agreement by and among the Company, the Sellers and the underwriters named therein (the “Underwriting Agreement”) no later than six (6) business days from the date hereof.

(c) The closing of the sale of the Repurchase Shares (the “Closing”) shall take place upon the same day as the Closing Date (as defined in the definitive Underwriting Agreement) at the offices of the Company in Vernon Hills, Illinois, or at such other time and place as may be agreed upon by the Company and the Sellers. At the Closing, each Seller shall deliver to the Company or as instructed by the Company duly executed stock powers relating to the Repurchase Shares sold by such Seller, as applicable, and the Company agrees to deliver to each Seller a dollar amount equal to the product of the Per Share Purchase Price and the number of Repurchase Shares sold by such Seller by wire transfer of immediately available funds.
