(iv)The stockholders of the Company approve a plan of complete liquidation or dissolution of the Company or the consummation of a sale of all or substantially all of the Company’s assets.

2.Payments Upon a Qualifying Termination.

(a)In the event of a Qualifying Termination, and provided the Executive executes a general release agreement substantially in the form of Exhibit B hereto (the “Release Agreement”) within sixty (60) days after the Date of Termination, and does not revoke such Release Agreement within seven (7) days after it has been executed, the Company shall provide to the Executive, in consideration of the general release set forth in Section 2 of the Release Agreement, the obligations of the Executive contained in the Noncompetition Agreement and other good and valuable consideration, the following benefits:

(i)Payment of an amount equal to (A) the Termination Year Bonus multiplied by a fraction, the numerator of which is the number of days of the fiscal year in which the Date of Termination occurs during which the Executive was employed by the Company and the denominator of which is 365, less (B) any amounts previously paid to the Executive in respect of such Termination Year Bonus during such fiscal year, such amount to be payable on the same basis and at the same time as if the Executive’s employment with the Company had continued (or at such other time as required by Section 9 hereof);

(ii)Continuation during the Severance Period (or at such other time as required by Section 9 hereof) in accordance with the Company’s regular payroll practices of salary replacement amounts equal to the Executive’s highest annual base salary from the Company and its Affiliates in effect during the 12-month period prior to the Date of Termination;

hundred percent (200%) of the average of the annual incentive bonuses paid or payable to Executive for each such year of employment);

(iv)Continuation, for the Severance Period, of medical, dental, disability, accident, life and similar insurance coverage on terms comparable to those which would have been provided if the Executive’s employment with the Company had continued for that time, with the payment for such insurance coverage to be made on the same basis as if the Executive’s employment with the Company had continued for that time, and subject to any withholding of applicable taxes with respect to such continued coverage; provided, however, that the Company’s obligation to provide each such type of insurance coverage shall cease as of the date that the Executive becomes eligible for such type of insurance coverage under a plan or agreement of a subsequent employer. The Executive shall be obligated to notify the Company of the Executive’s eligibility for insurance coverage under a plan or agreement of a subsequent employer on or before the date that such eligibility commences. If the Company determines that it is not reasonably practicable to provide a type of comparable insurance coverage required by this Section 2(a)(iv) for reasons other than cost, the Company shall reimburse the Executive for the amount necessary for the Executive to acquire comparable coverage, with such reimbursement, subject to applicable tax withholding, to be made no later than 90 days following the Company’s receipt of appropriate documentation from the Executive, but in no event later than end of the calendar year following the calendar year in which the expense was incurred. The Company’s obligation to make any such reimbursements for expenses not already incurred by the Executive shall cease at such time as the Executive becomes eligible under a plan or agreement of a subsequent employer for the type of insurance coverage for which the Executive is being compensated; and

(c)If the Executive breaches any of the covenants in the Noncompetition Agreement, including any noncompetition, nonsolicitation or confidentiality covenants contained therein, (i) the Executive’s entitlement to the payments and benefits set forth in Section 2(a) shall be null and void, (ii) all rights to receive or continue to receive severance payments and benefits shall thereupon cease and (iii) the Executive shall immediately repay to the Company all amounts theretofore paid to, and the value of all benefits theretofore received by, the Executive pursuant to Section 2(a). The foregoing shall not limit any other rights or remedies the Company may have existing in its favor, including injunctive relief.

3.Nonqualifying Termination of Employment. If the employment of the Executive shall terminate for any reason other than a Qualifying Termination, then the Company shall pay to the Executive all Accrued Obligations (including, in the case of death or disability, prorated annual incentive bonus (based on the target bonus under the Company’s Senior Management Incentive Plan or any successor plan for the fiscal year in which the Executive’s termination of employment occurs), through and including the effective date of the Executive’s termination of employment in a lump sum within thirty (30) days after the Date of Termination (or at such other time as required by Section 9 hereof); provided, however, that any portion of the Accrued Obligations that consists of bonus, deferred compensation or annual incentive compensation shall be determined and paid in accordance with the terms of the relevant plan as applicable to the Executive. In addition, if the Executive’s employment is terminated by retirement under a retirement plan of the Company or by resignation of the Executive other than for Good Reason, the Executive may, in the discretion of the Compensation Committee, be awarded a pro rata cash bonus for the year in which the Date of Termination occurs.

4.Section 280G.

(a)To the extent that any payment or distribution to or for the benefit of the Executive pursuant to the terms of this Agreement or any other plan, arrangement or agreement with the Company, any of its affiliated companies, any person whose actions result in a change of ownership or effective control covered by Section 280G(b)(2) of the Code or any person affiliated with the Company or such person, whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise (the “Payments”) would be

subject to the excise tax (the “Excise Tax”) imposed by Section 4999 of the Code, then the Company shall reduce the payments to the amount that is (after taking into account federal, state, local and social security taxes at the maximum marginal rates, including any excise taxes imposed by Section 4999 of the Code) one dollar less than the amount of the Payments that would subject the Executive to the Excise Tax (the “Safe Harbor Cap”) if, and only if, such reduction would result in Executive receiving a higher net after-tax amount. Unless Executive shall have given prior written notice specifying a different order to the Company to effectuate the Safe Harbor Cap, the Payments to be reduced hereunder will be determined in a manner which has the least economic cost to Executive and, to the extent the economic cost is equivalent, will be reduced in the inverse order of when the Payment would have been made to Executive until the reduction specified herein is achieved. Executive’s right to specify the order of reduction of the Payments shall apply only to the extent that it does not directly or indirectly alter the time or method of payment of any amount that is deferred compensation subject to (and not exempt from) Section 409A.

(b)All determinations required to be made under this Section 4, including whether and when the Safe Harbor Cap is required and the amount of the reduction of the Payments pursuant to the Safe Harbor Cap and the assumptions to be utilized in arriving at such determination, shall be made by a public accounting firm or other nationally recognized consulting firm with expertise in Section 280G of the Code that is retained by the Company as of the date immediately prior to the Change in Control (the “Calculating Firm”) which shall provide detailed supporting calculations both to the Company and Executive within fifteen (15) business days of the receipt of notice from the Company or Executive that there has been a Payment, or such earlier time as is requested by the Company (collectively, the “Determination”). In the event that the Calculating Firm is serving as accountant, auditor or consultant for the individual, entity or group effecting the Change in Control, Executive may appoint another nationally recognized public accounting or consulting firm to make the determinations required hereunder (which accounting firm shall then be referred to as the Calculating Firm hereunder). All fees and expenses of the Calculating Firm shall be borne solely by the Company and the Company shall enter into any agreement requested by the Calculating Firm in connection with the performance of the services hereunder. The Determination by the Calculating Firm shall be binding upon the Company and Executive. The Company shall bear and pay directly all costs and expenses incurred in connection with any contests or disputes with the Internal Revenue Service relating to the Excise Tax, and Executive shall cooperate, to the extent his or her reasonable out-of pocket expenses are reimbursed by the Company, with any reasonable requests by the Company in connection with any such contests or disputes.

5.Withholding Taxes. The Company may withhold from all payments due to the Executive (or the Executive’s beneficiary or estate) hereunder all taxes which, by applicable federal, state, local or other law, the Company is required to withhold therefrom. The Company may also reduce the amounts otherwise payable pursuant to Section 2(a) hereof to satisfy the Executive’s required contributions for the insurance coverage being provided hereunder.

6.Termination and Amendment of Agreement.

(a)This Agreement shall be effective as of the Effective Date and shall expire on January 1, 2026, provided that not later than nine months prior to the expiration of the term of this Agreement, the Company and the Executive shall review and discuss in good faith whether or not to renew, amend or replace the Agreement. If a Potential Change in Control occurs during the term of the Agreement, then in no event shall the Agreement expire earlier than the date such Potential Change in Control terminates without resulting in a Change in Control, and if a Change in Control occurs during the term of the Agreement, then in no event shall the Agreement expire earlier than the 24-month anniversary of such Change in Control. Notwithstanding the foregoing, any expiration or termination of this Agreement shall not retroactively impair or otherwise adversely affect the rights of the Executive which have arisen prior to the date of such expiration.

(b)No provision of this Agreement may be amended, modified or waived unless such amendment, modification or waiver is agreed to in writing and signed by the Executive and by a duly authorized officer of the Company; provided, however, that the Company may amend the Agreement in a manner that is beneficial to the interests of the Executive without the Executive’s written consent.

7.Scope of Agreement. Nothing in this Agreement shall be deemed to entitle the Executive to continued employment with the Company or its subsidiaries or any of their respective Affiliates. Any amount paid pursuant to Section 2 shall be paid in lieu of any other amount of severance relating to salary, incentive compensation or other bonus continuation to be received by the Executive from the Company or its Affiliates upon termination of employment of the Executive under any employment, employee benefit or severance plan or agreement, policy or similar arrangement of the Company or its Affiliates in effect as of the date hereof; provided, however, that nothing in this Section 7 shall affect the Executive’s rights with respect to any equity ownership interest in the Company. If the Company or any of its Affiliates are obligated by law to pay severance pay, notice pay or other similar benefits, or if the Company or any of its Affiliates are obligated by law to provide advance

notice of separation (“Notice Period”), then the payments made pursuant to Section 2 shall be reduced by the amount of any such severance, notice pay or other similar benefits, as applicable, and by the amount of any severance pay, notice pay or other similar benefits received during any Notice Period.

8.Successors; Binding Agreement.

(a)This Agreement shall not be terminated by any merger or consolidation of the Company whereby the Company is or is not the surviving or resulting corporation or as a result of any transfer of all or substantially all of the assets of the Company. In the event of any such merger, consolidation or transfer of assets, the provisions of this Agreement shall be binding upon the surviving or resulting corporation or the person or entity to which such assets are transferred. In the event of the consummation of a transaction initiated by the Company involving the formation of a direct or indirect holding company of the Company for any internal legal or business purpose in which the holders of the outstanding voting securities of the Company become the holders of the outstanding voting securities of such holding company in substantially the same proportions, the provisions of this Agreement shall be binding upon such holding company.

(b)The Company agrees that concurrently with any merger, consolidation or transfer of assets referred to in Section 8(a), it will cause any successor or transferee unconditionally to assume, by written instrument delivered to the Executive (or the Executive’s beneficiary or estate), all of the obligations of the Company hereunder. Failure of the Company to obtain such assumption prior to the effectiveness of any such merger, consolidation or transfer of assets shall be a breach of this Agreement and, if such merger, consolidation or transfer of assets is a “change in control event” within the meaning of Section 409A of the Code, shall entitle the Executive to compensation and other benefits from the Company in the same amount and on the same terms as the Executive would be entitled hereunder if the Executive’s employment were terminated by reason of a Qualifying Termination. For purposes of implementing the foregoing, the date on which any such merger, consolidation or transfer becomes effective shall be deemed the Date of Termination.

(c)This Agreement shall inure to the benefit of and be enforceable by the Executive’s personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees. If the Executive shall die while any amounts would be payable to the Executive hereunder had the Executive continued to live, all such amounts, unless otherwise provided herein, shall be paid in accordance with the terms of this Agreement to such person or persons appointed in writing by the Executive to receive such amounts or, if no person is so appointed, to the Executive’s estate.

9.Section 409A Compliance. This Agreement shall be interpreted and construed in a manner that avoids the imposition of additional taxes and penalties under Section 409A of the Code (“409A Penalties”), and all payments under the Agreement are subject to the terms of the policy established by the Company pursuant to Section 409A of the Code. In the event the terms of this Agreement would subject the Executive to 409A Penalties, the Company and the Executive shall cooperate diligently to amend the terms of the Agreement to avoid such 409A Penalties, to the extent possible, without adversely affecting the intended benefits hereunder. Notwithstanding any other provision in this Agreement, if on the Date of Termination (a) the Company is a publicly traded corporation and (b) the Executive is a “specified employee,” as defined in Section 409A of the Code, then to the extent any amount payable under this Agreement constitutes the payment of nonqualified deferred compensation, within the meaning of Section 409A of the Code, that under the terms of this Agreement would be payable prior to the six-month anniversary of the Date of Termination, such payment shall be delayed until the earlier to occur of (i) the six-month anniversary of the Date of Termination or (ii) the date of the Executive’s death.

10.Notices. (a) For purposes of this Agreement, all notices and other communications required or permitted hereunder shall be in writing and shall be deemed to have been duly given when delivered or five days after deposit in the United States mail, certified and return receipt requested, postage prepaid, addressed (i) if to the Executive, to the home address of the Executive on the most current Company records and if to the Company, to CDW Corporation, 200 North Milwaukee Avenue, Vernon Hills, IL 60061. attention General Counsel, or (ii) to such other address as either party may have furnished to the other in writing in accordance herewith, except that notices of change of address shall be effective only upon receipt.

(a)A written notice of the Executive’s Date of Termination by the Company or the Executive, as the case may be, to the other, shall (i) indicate the specific provision in this Agreement applicable to such termination, if any, (ii) to the extent applicable, set forth in reasonable detail the facts and circumstances claimed to provide a basis for the application of such provision to the termination of the Executive’s employment and (iii) specify the termination date (which date shall be not less than 30 days after the giving of such notice, unless the Company determines, in its sole discretion, that Executive’s Date of Termination shall be less than 30 days following a written notice provided by the Executive). The failure by the Executive or the Company to set forth in such notice any fact or circumstance which contributes to a showing of Good Reason or Cause shall not waive any

right of the Executive or the Company hereunder or preclude the Executive or the Company from asserting such fact or circumstance in enforcing the Executive’s or the Company’s rights hereunder.

11.Full Settlement; Resolution of Disputes. (a) The Company’s obligation to make any payments provided for in Section 2 of this Agreement and otherwise to perform its obligations thereunder shall not be affected by any set-off, counterclaim, recoupment, defense or other claim, right or action which the Company may have against the Executive or others, except as provided in Section 2(c) or Section 13. In no event shall the Executive be obligated to seek other employment or take any other action by way of mitigation of the amounts payable to the Executive under the provisions of Section 2 of this Agreement and such amounts shall not be reduced whether or not the Executive obtains other employment, except as provided in Section 2(c).

(a)Any dispute or controversy between the Company and the Executive arising out of or relating to this Agreement or the breach of this Agreement shall be settled by arbitration administered by the American Arbitration Association (“AAA”) in accordance with its Commercial Arbitration Rules then in effect, and judgment on the award rendered by the arbitrator may be entered in any court having jurisdiction thereof. Any arbitration shall be held before a single arbitrator who shall be selected by the mutual agreement of the Company and the Executive, unless the parties are unable to agree to an arbitrator, in which case the arbitrator will be selected under the procedures of the AAA. In connection with the appointment of an arbitrator, the AAA will give the parties a list of no less than 15 potential arbitrators to strike and number in order of preference in accordance with AAA procedures. The arbitrator shall have the authority to award any remedy or relief that a court of competent jurisdiction could order or grant, including, without limitation, the issuance of an injunction. However, either party may, without inconsistency with this arbitration provision, apply to any court otherwise having jurisdiction over such dispute or controversy and seek interim provisional, injunctive or other equitable relief until the arbitration award is rendered or the controversy is otherwise resolved. Except as necessary in court proceedings to enforce this arbitration provision or an award rendered hereunder, or to obtain interim relief, neither a party nor an arbitrator may disclose the existence, content or results of any arbitration hereunder without the prior written consent of the Company and the Executive. The Company and the Executive acknowledge that this Agreement evidences a transaction involving interstate commerce. Notwithstanding any choice of law provision included in this Agreement, the United States Federal Arbitration Act shall govern the interpretation and enforcement of this arbitration provision. The arbitration proceeding shall be conducted in Chicago, Illinois or such other location to which the parties may agree. The Company shall pay the costs of any arbitrator appointed hereunder.

(b)If a claim or dispute arises after a Change in Control concerning the rights of the Executive under this Agreement, regardless of the party by whom such claim or dispute is initiated, the Company shall pay all legal expenses, including reasonable attorneys’ fees, court costs, and ordinary and necessary out-of-pocket costs of attorneys, billed to and payable by the Executive, in connection with the bringing, prosecuting, defending, litigating, negotiating, or settling such claim or dispute; provided that if the Executive does not prevail on at least one material claim in connection with such claim or dispute, the Executive’s right to such payments shall cease and the Executive shall be required to return any amounts advanced by the Company pursuant to this Section 11(c). For purposes of complying with the requirements of Section 409A of the Code, (i) the right of the Executive to reimbursement pursuant to this Section 11(c) shall apply until the tenth anniversary of the Date of Termination, (ii) the amount of expenses eligible for reimbursement during a calendar year shall not affect the expenses eligible for reimbursement in any other calendar year, (iii) the reimbursement of an expense must be paid to the Executive on or before the last day of the calendar year following the calendar year in which the expense was incurred and (iv) the right to reimbursement is not subject to liquidation or exchange for another benefit.

12.Employment with Affiliates. Employment with the Company for purposes of this Agreement shall include employment with any Affiliate of the Company.

13.Clawback Policy. Notwithstanding anything to the contrary herein, all incentive compensation paid to the Executive in connection with the Executive’s employment with the Company shall be subject to forfeiture, recovery by Company or other action pursuant to any clawback or recoupment policy which the Company may adopt from time to time to the extent the Board determines in good faith that the adoption and maintenance of such policy is necessary to comply with the Dodd-Frank Wall Street Reform and Consumer Protection Act and implementing rules and regulations thereunder, or is otherwise required by applicable law.
