CDW Corporation, a Delaware corporation (the “Company”), hereby grants to the individual (the “Holder”) named in the award notice attached hereto (the “Award Notice”) as of the date set forth in the Award Notice (the “Grant Date”), pursuant to the provisions of the CDW Corporation Amended and Restated 2013 Long-Term Incentive Plan (the “Plan”), a restricted stock unit award (the “Award”) with respect to the number of shares of the Company’s Common Stock, par value $0.01 per share (“Stock”), set forth in the Award Notice, upon and subject to the restrictions, terms and conditions set forth in the Plan and this agreement (the “Agreement”). Capitalized terms not defined herein shall have the meanings specified in the Plan.

1.Award Subject to Acceptance of Agreement. The Award shall be null and void unless the Holder accepts this Agreement by executing the Award Notice in the space provided therefor and returning an original execution copy of the Award Notice to the Company (or electronically accepting this Agreement within the Holder’s stock plan account with the Company’s stock plan administrator according to the procedures then in effect).

2.    Rights as a Stockholder. The Holder shall not be entitled to any privileges of ownership with respect to the shares of Stock subject to the Award unless and until, and only to the extent, such shares become vested pursuant to Section 3 hereof and the Holder becomes a stockholder of record with respect to such shares. As of each date on which the Company pays a cash dividend to record owners of shares of Stock (a “Dividend Date”), then the number of shares subject to the Award shall increase by (i) the product of the total number of shares subject to the Award immediately prior to such Dividend Date multiplied by the dollar amount of the cash dividend paid per share of Stock by the Company on such Dividend Date, divided by (ii) the Fair Market Value of a share of Stock on such Dividend Date. Any such additional shares shall be subject to the same vesting conditions and payment terms set forth herein as the shares to which they relate.

3.    Restriction Period and Vesting.

3.1.    Service-Based Vesting Condition. Except as otherwise provided in this Section 3, the Award shall vest in accordance with the vesting schedule set forth in the Award Notice, provided the Holder continuously serves as a Non-Employee Director through such date. The period of time prior to such vesting shall be referred to herein as the “Restriction Period.”

3.2.    Termination of Service.

(a)    Death or Disability. If the Holder’s service as a Non-Employee Director terminates prior to the end of the Restriction Period by reason of the Holder’s death or Disability, then in either case, the Award shall be 100% vested upon such termination of service. For purposes of this Award, “Disability” shall mean the Holder’s absence from the Holder’s duties with the Company on a full-time basis for at least 180 consecutive days as a result of the Holder’s incapacity due to physical or mental illness.

(b)    Failure to Stand for Re-election. If the Holder’s service as a Non-Employee Director terminates prior to the end of the Restriction Period by reason of the Holder’s failure to be nominated or otherwise stand for re-election to the Board at an annual meeting of the Company that occurs during the Restriction Period, then a prorated portion of the Award shall become vested as of the date of the annual meeting on which the Holder’s service on the Board ceases, determined by multiplying the number of Shares subject to the Award by a fraction, the numerator of which shall be the number of days from the Grant Date until the date on which the Holder’s service on the Board ceases and the denominator of which shall be 365.

(c)    Termination of Service other than due to Death or Disability or Failure to Stand for Re-Election. If the Holder’s service as a Non-Employee Director terminates prior to the end of the Restriction Period or prior to the occurrence of a Change in Control for any reason other than due to death, Disability or failure to be nominated or otherwise stand for re-election to the Board, then the Award shall be immediately forfeited by the Holder and cancelled by the Company unless otherwise determined by the Board in connection with such termination.

3.3.    Change in Control. Upon a Change in Control, the Restriction Period shall lapse and the Award shall become fully vested.

4.    Issuance or Delivery of Shares.  Subject to the terms of this Agreement and any deferral election made by the Holder pursuant to Section 5, as soon as practicable (but no later than thirty (30) days) after the vesting of the Award, the Company shall issue or deliver, subject to the conditions of this Agreement, the vested shares of Stock to the Holder. Such issuance or delivery shall be evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company. The Company shall pay all original issue or transfer taxes and all fees and expenses incident to such issuance or delivery.  Prior to the issuance to the Holder of the shares of Stock subject to the Award, the Holder shall have no direct or secured claim in any specific assets of the Company or in such shares of Stock, and will have the status of a general unsecured creditor of the Company.
