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 2021 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 set forth in the Award Notice, upon and subject to the restrictions, terms and conditions set forth below, in the Award Notice and in the Plan. Capitalized terms not defined herein shall have the meanings specified in the Plan.

2. Rights as a Stockholder. The Holder shall not be entitled to any privileges of ownership with respect to the shares of Common 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 Common Stock (a “Dividend Date”), the Holder shall have no entitlement to receive such cash dividend, and 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 Common Stock by the Company on such Dividend Date, divided by (ii) the Fair Market Value of a share of Common 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.

(a) Termination of Employment Due to Death or Disability. If the Holder’s employment with the Company and/or a Subsidiary terminates prior to the end of the Restriction Period by reason of the Holder’s death or Disability, then in any such case, the Award shall be 100% vested upon such termination of employment; provided that in the case of a termination due to Disability, (i) the Holder executes and does not revoke a waiver and release of claims in

the form prescribed by the Company within 60 days after the date of such termination and (ii) to the extent the Award is subject to Section 409A of the Code because the Holder is or will become eligible for Retirement during the Restriction Period and the Holder’s Disability does not constitute a ”Disability” within the meaning of Section 409A of the Code, then the Award shall be fully vested as of the date of such termination, but the shares of Common Stock subject to the Award shall be issued or delivered to the Holder in accordance with the vesting schedule set forth in the Award Notice.

(b) Termination of Employment due to Retirement. If the Holder’s employment with the Company and/or a Subsidiary terminates prior to the end of the Restriction Period by reason of the Holder’s Retirement, as defined below, then the Award shall continue to vest in accordance with the vesting schedule set forth in the Award Notice, provided that the Holder complies with all Restrictive Covenants through the expiration of the Restriction Period.

(c) Termination of Employment Other Than Due to Death, Disability or Retirement. If the Holder’s employment with the Company and/or a Subsidiary terminates prior to the end of the Restriction Period and prior to a Change in Control for any reason other than death, Disability or Retirement, then the Award shall be immediately and automatically forfeited by the Holder and cancelled by the Company.

(a) Vesting and Settlement of Award Not Assumed. In the event of a Change in Control prior to the end of the Restriction Period pursuant to which the Award is not effectively assumed or continued by the surviving or acquiring corporation in such Change in Control (as determined by the Board or Committee, with appropriate adjustments to the number and kind of shares, in each case, that preserve the value of the shares subject to the Award and other material terms and conditions of the outstanding Award as in effect immediately prior to the Change in Control), the Award shall vest in its entirety as of the date of the Change in Control. To the extent the Award is subject to Section 409A of the Code because the Holder is or will become eligible for Retirement during the Restriction Period and the Award cannot be settled at the time of the Change in Control in compliance with Section 409A of the Code, then the Award shall be fully vested as of the date of the Change in Control but shall be paid pursuant to Section 3.3(b).

(b) Vesting and Settlement of Award Assumed. In the event of a Change in Control prior to the end of the Restriction Period pursuant to which the Award is effectively assumed or continued by the surviving or acquiring corporation in such Change in Control (as determined by the Board or Committee, with appropriate adjustments to the number and kind of shares, in each case, that preserve the value of the shares subject to the Award and other material terms and conditions of the outstanding Award as in effect immediately prior to the Change in Control) and (i) the Holder remains continuously employed through the end of the Restriction Period, (ii) the Company terminates the Holder’s employment without Cause or the Holder resigns for Good Reason within 24 months following such Change in Control and the Holder executes and does not revoke a waiver and release of claims in the form prescribed by the Company within 60 days after the date of such termination or (iii) the Holder terminates

employment due to Retirement or (iv) the Holder’s employment terminates due to death or Disability following such Change in Control and, in the case of a termination due to Disability, the Holder executes and does not revoke a waiver and release of claims in the form prescribed by the Company within 60 days after the date of such termination, then in any such case, the Award shall become fully vested as of the end of the Restriction Period or, if earlier, the Holder’s termination of employment. If, following a Change in Control, the Holder experiences a termination of employment other than as set forth in this Section 3.3(b) or in Section 3.2(a) or 3.2(b), the Award shall be immediately and automatically forfeited by the Holder and cancelled by the Company. Notwithstanding the foregoing, to the extent the Award is subject to Section 409A of the Code because the Holder is or will become eligible for Retirement during the Restriction Period and the Award cannot be settled at the time of the Holder’s termination of employment under clause (ii) or (iii) herein in compliance with Section 409A of the Code (for example, because the Change in Control does not constitute a “change in control event” within the meaning of Section 409A of the Code), then the Award shall be fully vested as of the date of such termination but shall be settled in accordance with Section 3.2 of this Agreement.

(b) Disability. 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, or under such other circumstances as the Committee determines, in its sole discretion, constitute a Disability.

(e) Retirement. For purposes of this Award, “Retirement” shall mean a termination of the Holder’s employment for a reason other than Cause after (A) the Holder has attained age 55 and (B) the sum of the Holder’s age and years of employment with or service to the Company or its Subsidiaries equals or exceeds 65; provided that such termination occurs at least six months after the Grant Date.

of the calendar year in which the Holder vests under Section 3.2(a)), the Company shall issue or deliver, subject to the conditions of this Agreement, the vested shares of Common 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, except as otherwise provided in Section 7. Prior to the issuance to the Holder of the shares of Common 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 Common Stock, and will have the status of a general unsecured creditor of the Company. The Holder shall have no beneficial interest or ownership in the vested shares of Common Stock until the issuance or delivery of those vested shares of Common Stock to the Holder.

5.1. Clawback of Proceeds. This award is subject to the clawback provisions in Section 5.15 of the Plan. In addition, if the Holder materially violates any Restrictive Covenant and such violation occurs on or before the third anniversary of the date of the Holder’s termination of employment: (i) the Award shall be forfeited and (ii) any and all Award Proceeds (as hereinafter defined) shall be immediately due and payable by the Holder to the Company. For purposes of this Section, “Award Proceeds” shall mean, with respect to any portion of the Award which is settled later than 24 months prior to the date of the Holder’s termination of employment or service with the Company the Fair Market Value of a share of Common Stock on the date such portion of the Award was settled, multiplied by the number of shares of Common Stock issued to the Holder pursuant to the settlement of such portion of the Award. The remedy provided by this Section shall be in addition to and not in lieu of any rights or remedies which the Company may have against the Holder in respect of a breach by the Holder of any duty or obligation to the Company.

5.2. Right of Setoff. The Holder agrees that by accepting the Award the Holder authorizes the Company and its affiliates to deduct any amount or amounts owed by the Holder pursuant to this Section 5 from any amounts payable by or on behalf of the Company or any affiliate to the Holder, including, without limitation, any amount payable to the Holder as salary, wages, vacation pay, bonus or the vesting or settlement of the Award or any stock-based award. This right of setoff shall not be an exclusive remedy and the Company’s or an affiliate’s election not to exercise this right of setoff with respect to any amount payable to the Holder shall not constitute a waiver of this right of setoff with respect to any other amount payable to the Holder or any other remedy.

6.1. Nontransferability of Award. The Award may not be transferred by the Holder other than by will or the laws of descent and distribution or pursuant to the designation of one or more beneficiaries on the form prescribed by the Company. Except to the extent permitted by the foregoing sentence, the Award may not be sold, transferred, assigned, pledged, hypothecated, encumbered or otherwise disposed of (whether by operation of law or otherwise) or be subject to execution, attachment or similar process. Upon any attempt to so sell, transfer,

6.2. Investment Representation. The Holder hereby covenants that (a) any sale of any share of Common Stock acquired upon the vesting of the Award shall be made either pursuant to an effective registration statement under the Securities Act of 1933, as amended (the “Securities Act”), and any applicable state securities laws, or pursuant to an exemption from registration under the Securities Act and such state securities laws and (b) the Holder shall comply with all regulations and requirements of any regulatory authority having control of or supervision over the issuance of the shares and, in connection therewith, shall execute any documents which the Company shall in its sole discretion deem necessary or advisable.

(a) As a condition precedent to the issuance of Common Stock following the vesting of the Award, the Holder shall pay to the Company or one of its affiliates such amount as the Company or an affiliate determines is required, under all applicable federal, state, local or other laws or regulations, to be withheld and paid over as income tax, social charges, national insurance contributions (other than employer national insurance contributions) or other withholding taxes (the “Required Tax Payments”) with respect to the Award and/or the delivery of the Common Stock. If the Holder shall fail to advance the Required Tax Payments after request by the Company or one of its affiliates, the Company or one of its affiliates may, in its discretion, deduct any Required Tax Payments from any amount then or thereafter payable by the Company or one of its affiliates to the Holder.

(b) The Holder may elect to satisfy his or her obligation to advance the Required Tax Payments by any of the following means: (i) a cash payment to the Company or one of its affiliates; (ii) to the extent permitted by the Committee, delivery to the Company (either actual delivery or by attestation procedures established by the Company) of previously owned whole shares of Common Stock having an aggregate Fair Market Value, determined as of the date on which such withholding obligation arises (the “Tax Date”), equal to the Required Tax Payments; (iii) authorizing the Company to withhold whole shares of Common Stock which would otherwise be delivered to the Holder having an aggregate Fair Market Value, determined as of the Tax Date, equal to the Required Tax Payments; or (iv) any combination of (i), (ii) and (iii). Shares of Common Stock to be delivered or withheld may not have a Fair Market Value in excess of the amount determined by applying the maximum individual statutory tax rate in the Holder jurisdiction; provided that the Committee shall be permitted to limit the number of shares so delivered or withheld to a lesser number if necessary, as determined by the Committee, to avoid adverse accounting consequences or for administrative convenience; provided, however, that if a fraction of a share of Common Stock would be required to satisfy the maximum individual statutory rate in the Holder’s jurisdiction, then the number of shares of Common Stock to be delivered or withheld may be rounded up to the next nearest whole share of Common Stock. No share of Common Stock or certificate representing a share of Common Stock shall be issued or delivered until the Required Tax Payments have been satisfied in full.

7.2. Compliance with Applicable Law. The Award is subject to the condition that if the listing, registration or qualification of the shares subject to the Award upon any securities exchange or under any law, or the consent or approval of any governmental body, or the taking of any other action is necessary or desirable as a condition of, or in connection with, the delivery of shares hereunder, the shares of Common Stock subject to the Award shall not be delivered, in whole or in part, unless such listing, registration, qualification, consent, approval or other action shall have been effected or obtained, free of any conditions not acceptable to the Company. The Company agrees to use reasonable efforts to effect or obtain any such listing, registration, qualification, consent, approval or other action.

7.3. Award Confers No Rights to Continued Employment. In no event shall the granting of the Award or its acceptance by the Holder, or any provision of the Agreement or the Plan, give or be deemed to give the Holder any right to continued employment by the Company, any Subsidiary or any affiliate of the Company or affect in any manner the right of the Company, any Subsidiary or any affiliate of the Company to terminate the employment of any person at any time.

7.6. Notices. All notices, requests or other communications provided for in this Agreement shall be made, if to the Company, to CDW Corporation, Attn: General Counsel, 200 N. Milwaukee Avenue, Vernon Hills, Illinois 60061, and if to the Holder, to the last known mailing address of the Holder contained in the records of the Company. All notices, requests or other communications provided for in this Agreement shall be made in writing either (a) by personal delivery, (b) by facsimile or electronic mail with confirmation of receipt, (c) by mailing in the United States mails or (d) by express courier service. The notice, request or other communication shall be deemed to be received upon personal delivery, upon confirmation of receipt of facsimile or electronic mail transmission or upon receipt by the party entitled thereto if by United States mail or express courier service; provided, however, that if a notice, request or other communication sent to the Company is not received during regular business hours, it shall be deemed to be received on the next succeeding business day of the Company.

7.9. Entire Agreement. This Agreement and the Plan constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and the Holder with respect to the subject matter hereof, and may not be modified adversely to the Holder’s interest except by means of a writing signed by the Company and the Holder.

7.11. Amendment and Waiver. The Company may amend the provisions of this Agreement at any time; provided that an amendment that would adversely affect the Holder’s rights under this Agreement shall be subject to the written consent of the Holder. No course of conduct or failure or delay in enforcing the provisions of this Agreement shall affect the validity, binding effect or enforceability of this Agreement.

7.12. Compliance With Section 409A of the Code. This Award is intended to be exempt from or comply with Section 409A of the Code, and shall be interpreted and construed accordingly. To the extent this Agreement provides for the Award to become vested and be settled upon the Holder’s termination of employment, the applicable shares of Common Stock shall be transferred to the Holder or his or her beneficiary upon the Holder’s “separation from service,” within the meaning of Section 409A of the Code; provided that if the Holder is a “specified employee,” within the meaning of Section 409A of the Code, then to the extent the Award constitutes nonqualified deferred compensation, within the meaning of Section 409A of the Code, such shares of Common Stock shall be transferred to the Holder or his or her beneficiary upon the earlier to occur of (i) the six-month anniversary of such separation from service and (ii) the date of the Holder’s death.
