Company and its Subsidiaries. No act or failure to act will be considered “willful” (x) unless it is done, or omitted to be done, by Optionee in bad faith or without reasonable belief that Optionee’s action or omission was in the

confidentiality or protection of trade secrets (or similar provision regarding intellectual property), including Section 5 of this Agreement: (i) the Option shall be forfeited and (ii) the Optionee shall immediately remit a
cash payment to the Company equal to the difference between (A) the Fair Market Value of a share of Common Stock on the date on which the Company first became aware of such violation or the date of Optionee’s termination of employment,
whichever is greater, and (B) the per share Exercise Price, multiplied by (y) the number of shares of Common Stock purchased pursuant to the exercise of the Option. The remedy provided by this Section 3 shall terminate at such
time as the Institutional Investors (as defined below) collectively hold less than 10% of the number of shares of Common Stock held by the Institutional Investors as a result of the Distribution (as defined below). In addition, the remedy provided

3.2. Right of Setoff. The Optionee agrees that by accepting the Award Notice the Optionee authorizes the Company and its
affiliates to deduct any amount or amounts owed by the Optionee pursuant to this Section 3 from any amounts payable by or on behalf of the Company or any affiliate to the Optionee, including, without limitation, any amount payable to the
Optionee as salary, wages, vacation pay, bonus or the settlement of the Option 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

 4. Transfer Restrictions and Investment Representations. 

4.1. Nontransferability of Option. The Option may not be transferred by Optionee 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, (i) during Optionee’s lifetime the Option is exercisable only by
Optionee or Optionee’s legal representative, guardian or similar person and (ii) the Option 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, assign, pledge, hypothecate, encumber or otherwise dispose of the Option, the Option and all rights hereunder shall immediately become null and void.

 4.2. Investment Representation. Optionee hereby represents and covenants that (a) any shares of Common Stock
purchased upon exercise of the Option will be purchased for investment and not with a view to the distribution thereof within the meaning of the Securities Act of 1933, as amended (the “Securities Act”), unless such purchase has
been registered under the Securities Act and any applicable state securities laws; (b) any subsequent sale of any such shares shall be made either pursuant to an effective registration statement under 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 (c) if requested by the Company, Optionee shall submit a written statement, in a form satisfactory to the Company, to
the effect that such representation (x) is true and correct as of the date of any purchase of any shares hereunder or (y) is true and correct as of the date of any sale of any such shares, as applicable. As a further condition precedent to
any exercise of the Option, Optionee shall comply with all regulations and requirements of any regulatory authority having control of or supervision over the issuance or delivery of the shares and, in connection therewith, shall execute any
documents which the Board or the Committee shall in its sole discretion deem necessary or advisable. 
 5. Noncompete,
Nonsolicitation and Confidentiality. Optionee acknowledges that in the course of his or her employment with or provision of services to the Company or its Subsidiaries, Optionee has and will become familiar with trade secrets and other
confidential information concerning the Company and its Subsidiaries and that Optionee’s services will be of special, unique and extraordinary value to the Company and its Subsidiaries. Optionee also acknowledges that the Company’s
Confidential Information (as this and other terms used herein are defined below) will retain continuing vitality throughout and beyond the Noncompetition Period, and that should Optionee leave the Company and work for a Competitor during the
Noncompetition Period, it would be highly likely, if not inevitable, that Optionee would use or disclose the Company’s Confidential Information. For these and other reasons, Optionee agrees and acknowledges that the restrictions in this
Agreement are reasonable and necessary to protect the Company’s legitimate business interests. 
 5.1. Noncompete.
In consideration for the issuance of the Option and other good and valuable consideration, Optionee agrees not to become employed by, perform services for, form, develop, or otherwise become associated with (as an employee, officer, director,
manager, partner or consultant or member, stockholder or investor owning more than a 2% interest or other similar role) a Competitor of the Company or any of its Subsidiaries at any time 

  
 5 

 
during Optionee’s employment with or service to the Company or any of its Subsidiaries or for eighteen months after the termination of Optionee’s employment with or service to the
Company or any of its Subsidiaries (the “Noncompetition Period”). For purposes of this Section 5, “Competitor” shall mean any Person conducting or planning to conduct a business similar to and in
competition with any business conducted or planned by the Company or any of its Subsidiaries in any geographic area in which the Company or any of its Subsidiaries is conducting such business or plans to conduct such business as of the date of
termination of Optionee’s employment with or services to the Company or its Subsidiaries, if Optionee, while employed by or providing services to the Company or any of its Subsidiaries, was involved in such business or had knowledge of the
operations of such business or received or was otherwise in possession of Confidential Information as defined in Section 5.6 regarding such business. For purposes of illustration only, the parties agree that each of the corporations,
other enterprises or Persons set forth on Schedule I attached hereto is a “Competitor” of the Company and its Subsidiaries as of the date hereof, it being acknowledged and agreed that (x) such list is only representative of the
Company’s current Competitors but not exhaustive and is not intended to include all of the Company’s or its Subsidiaries’ current Competitors and (y) other Persons could become Competitors of the Company or its Subsidiaries at a
future date. 
 5.2. Nonsolicitation. Optionee further agrees that during the Noncompetition Period Optionee shall not
(i) in any manner, directly or indirectly, solicit any CDW Employee or induce or attempt to induce any CDW Employee to terminate or abandon his or her employment for any purpose whatsoever or (ii) on behalf of any Competitor, call on,
service, solicit or otherwise do business with any CDW Vendor or CDW Customer. 
 5.3. Exceptions. Nothing in this
Section 5 shall prohibit Optionee from being (i) a stockholder in a mutual fund or a diversified investment company or (ii) an owner of not more than two percent of the outstanding stock of any class of a corporation, any
securities of which are publicly traded, so long as Optionee has no active participation in the business of such corporation. 

5.4. Extension. Because the protection of the Company’s Confidential Information requires that Optionee not perform the
activities described in Sections 5.1 and 5.2 for the full Noncompetition Period, Optionee agrees that the Noncompetition Period provided in Section 5 shall be extended for any time during which Optionee breaches this
Agreement, such that Optionee does not perform the proscribed activities for a time period equal to the full amount of time provided in Section 5. 
 5.5. Reformation. If, at any time of enforcement of this Section 5, a court or an arbitrator holds that the restrictions stated herein are unreasonable under circumstances then
existing, the parties hereto agree that the maximum period, scope or geographical area reasonable under such circumstances shall be substituted for the stated period, scope or area and that the court or arbitrator shall be allowed to revise the
restrictions contained herein to cover the maximum period, scope and area permitted by law. This Agreement shall not authorize a court or arbitrator to increase or broaden any of the restrictions in this Section 5. 

5.6. Confidentiality. Other than as required in the ordinary course of Optionee’s employment by the Company or its
Subsidiaries, and except as specifically 

  
 6 

 
authorized by the Board or Optionee’s direct supervisor, Optionee shall not at any time make use of or disclose, directly or indirectly, any (i) trade secret or other confidential or
secret information of the Company or of any of its Subsidiaries or (ii) other technical, business, proprietary or financial information of the Company or of any of its Subsidiaries not available to the public generally or to Competitors
(“Confidential Information”), except to the extent that such Confidential Information (a) becomes a matter of public record or is published in a newspaper, magazine or other periodical or on electronic or other media available
to the general public, other than as a result of any act or omission by Optionee or (b) is required to be disclosed by any law, regulation or order of any court or regulatory commission, department or agency, provided that Optionee gives prompt
notice of such requirement to the Company to enable the Company to seek an appropriate protective order. Promptly following the termination of Optionee’s employment or service with the Company or any of its Subsidiaries, Optionee shall
surrender to the Company all records, memoranda, notes, plans, reports, computer tapes and software and other documents and data which constitute Confidential Information which Optionee may then possess or have under his/her control (together with
all copies thereof). 
 5.7. Acknowledgements. Optionee acknowledges that the provisions of this Section 5
are in addition to, and not in limitation of, any obligation of Optionee under the terms of any employment or other agreement with the Company or any Subsidiary, and in consideration of (i) employment by the Company or its Subsidiaries or
retention to provide services to the Company and its Subsidiaries and (ii) additional good and valuable consideration as set forth in this Agreement. In addition, Optionee agrees and acknowledges that the restrictions contained in this
Section 5 do not preclude Optionee from earning a livelihood, nor do they unreasonably impose limitations on Optionee’s ability to earn a living. In addition, Optionee acknowledges (i) that the business of the Company or its
Subsidiaries will be conducted throughout the United States, (ii) notwithstanding the state of incorporation or principal office of the Company or its Subsidiaries, or any of their respective executives or employees (including Optionee), it is
expected that the Company or its Subsidiaries will have business activities and have valuable business relationships within its industry throughout the United States, and (iii) as part of Optionee’s responsibilities, Optionee will be
conducting business throughout the United States in furtherance of the Company’s business and its relationships. Optionee agrees and acknowledges that the potential harm to the Company and its Subsidiaries of the non-enforcement of this
Section 5 outweighs any potential harm to Optionee of its enforcement by injunction or otherwise. Optionee acknowledges that Optionee has carefully read this Agreement and has given careful consideration to the restraints imposed upon
Optionee by this Agreement, and is in full accord as to their necessity for the reasonable and proper protection of confidential and proprietary information of the Company, its Subsidiaries and Affiliates now existing or to be developed in the
future. Optionee expressly acknowledges and agrees that each and every restraint imposed by this Agreement is reasonable with respect to subject matter, time period and geographical scope. 

5.8. Definitions. For purposes of this Section 5 the following terms shall have the following meanings: 

(a) “CDW Customer” means (i) any person or entity that purchased any products or services from the Company or any
of its Subsidiaries or affiliates at any time within 

  
 7 

 
a two year period prior to Optionee’s termination (for whatever reason) from the Company or (ii) any person or entity with respect to whom, at any time during the one year period prior
to Optionee’s termination (for whatever reason) from the Company, Optionee submitted or assisted in the development or submission of a presentation or proposal of any kind on behalf of the Company or any of its Subsidiaries or affiliates,
acquired or had access to any Confidential Information or had contact with as a result of Optionee’s employment with the Company. 
 (b) “CDW Employee” means any person who was an officer, manager-level or other key employee or any material group of employees of the Company or any of its Subsidiaries or affiliates
either (i) at any time within three months of the prohibited contact; or (ii) at any time within three months of Optionee’s termination (for whatever reason) from the Company. 

(c) “CDW Vendor” means any person or entity that provided goods or services to the Company or any of its Subsidiaries or
otherwise did business with the Company or any of its Subsidiaries at any time within a two-year period prior to Optionee’s termination (for whatever reason) from the Company. 

(d) “Person” means any individual, partnership, corporation, association, joint stock company, trust, joint venture,
limited liability company, unincorporated organization, governmental entity or department, agency or political subdivision thereof. 
 5.9. Remedies. The parties hereto shall be entitled to enforce their respective rights under this Agreement specifically, to recover damages by reason of any breach of any provision of this
Agreement, and to exercise all other rights existing in their favor. The parties hereto acknowledge and agree that money damages would not be an adequate remedy for any breach of the provisions of this Agreement and that any party hereto may, in
their sole discretion, apply to any court of law or equity of competent jurisdiction for specific performance and/or injunctive relief (without posting bond or other security) in order to enforce or prevent any violation of the provisions of this
Agreement. 
 6. Additional Terms and Conditions. 

6.1. Withholding Taxes. (a) As a condition precedent to the issuance of Common Stock following the exercise of the Option,
Optionee shall, upon request by the Company, pay to the Company in addition to the purchase price of the shares, such amount as the Company may be required, under all applicable federal, state, local or other laws or regulations, to withhold and pay
over as income or other withholding taxes (the “Required Tax Payments”) with respect to such exercise of the Option. If Optionee shall fail to advance the Required Tax Payments after request by the Company, the Company may, in its
discretion, deduct any Required Tax Payments from any amount then or thereafter payable by the Company to Optionee. 
 (b)
Optionee 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; (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 

  
 8 

 
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) to the extent permitted by the Committee, authorizing the Company to withhold whole shares of Common Stock which would otherwise be delivered to Optionee upon exercise of the Option having an aggregate Fair Market Value, determined as of
the Tax Date, equal to the Required Tax Payments; (iv) except as may be prohibited by applicable law, a cash payment by a broker-dealer acceptable to the Company to whom Optionee has submitted an irrevocable notice of exercise or (v) 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 minimum amount of the Required Tax Payments; provided, however, that if a fraction of a share
of Common Stock would be required to satisfy the minimum amount of the Required Tax Payments, 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. 
 6.2. Adjustment. In the event of any equity restructuring (within the meaning of Financial Accounting Standards Board Accounting Standards Codification Topic 718, Compensation—Stock
Compensation) that causes the per share value of shares of Common Stock to change, such as a stock dividend, stock split, spinoff, rights offering or recapitalization through an extraordinary dividend, the number and class of securities subject to
the Option and the Exercise Price shall be equitably adjusted by the Committee, such adjustment to be made in accordance with Section 409A of the Code. In the event of any other change in corporate capitalization, including a merger,
consolidation, reorganization, or partial or complete liquidation of the Company, such equitable adjustments described in the foregoing sentence may be made as determined to be appropriate and equitable by the Committee (or, if the Company is not
the surviving corporation in any such transaction, the board of directors of the surviving corporation) to prevent dilution or enlargement of rights of participants. The decision of the Committee regarding any such adjustment shall be final, binding
and conclusive. 
 6.3. Compliance with Applicable Law. The Option is subject to the condition that if the listing,
registration or qualification of the shares subject to the Option 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 purchase or issuance of shares hereunder, the Option may not be exercised, in whole or in part, and such shares may not be issued, 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. 

6.4. Issuance or Delivery of Shares. Upon the exercise of the Option, in whole or in part, the Company shall issue or deliver,
subject to the conditions of this Agreement, the number of shares of Common Stock purchased against full payment therefor. Such issuance 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, except as otherwise provided in Section 6.1.

 6.5. Option Confers No Rights as Stockholder. Optionee shall not be entitled to any
privileges of ownership with respect to shares of Common Stock subject to the Option unless and until such shares are purchased and issued upon the exercise of the Option, in whole or in part, and Optionee becomes a stockholder of record with
respect to such issued shares. Optionee shall not be considered a stockholder of the Company with respect to any such shares not so purchased and issued. 
 6.6. Option Confers No Rights to Continued Employment. In no event shall the granting of the Option or its acceptance by Optionee, or any provision of this Agreement or the Plan, give or be deemed
to give Optionee 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. 
 6.7. Decisions of Board or Committee. The Board or the Committee shall have the right to resolve
all questions which may arise in connection with the Option or its exercise. Any interpretation, determination or other action made or taken by the Board or the Committee regarding the Plan or this Agreement shall be final, binding and conclusive.

Form of Stock Option Agreement 
 CDW Corporation, a Delaware corporation (the “Company”), hereby grants to the individual (“Optionee”) named in the award notice attached hereto (the “Award
Notice”) as of the date set forth in the Award Notice (the “Option Date”), pursuant to the provisions of the CDW Corporation 2013 Long-Term Incentive Plan (the “Plan”), an option to purchase from the
Company the number of shares of the Company’s Common Stock, par value $0.01 per share (“Common Stock”), set forth in the Award Notice at the price per share set forth in the Award Notice (the “Exercise Price”)
(the “Option”), upon and subject to the 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. 

1. Option Subject to Acceptance of Agreement. The Option shall be null and void unless Optionee shall accept 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 Optionee’s stock plan account with the Company’s
stock plan administrator according to the procedures then in effect). In addition, in the event that the Company’s initial public offering of the Common Stock (the “IPO”) does not close on or before August 31, 2013, this
Option shall be forfeited as of such date. 
 2. Time and Manner of Exercise of Option. 

2.1. Maximum Term of Option. In no event may the Option be exercised, in whole or in part, after the expiration date set forth in
the Award Notice (the “Expiration Date”). 
 2.2. Vesting and Exercise of Option. The Option shall
become vested and exercisable in accordance with the vesting schedule set forth in the Award Notice (the “Vesting Schedule”). The Option shall be vested and exercisable following a termination of Optionee’s employment according
to the following terms and conditions: 
 (a) Termination of Employment due to Death or Disability. If Optionee’s
employment with the Company terminates by reason of Optionee’s death or Disability, then in either such case the Option shall become vested as of the date of termination with respect to a number of additional shares of Common Stock that would
have become vested during the one-year period following the date of such termination if Optionee’s employment with the Company had continued through such date, and the Option may thereafter be exercised by Optionee or Optionee’s executor,
administrator, legal representative, guardian or similar person until and including the earlier to occur of (i) the date which is one year after the date of termination of employment and (ii) the Expiration Date. Except to the extent the
Option is vested and exercisable as of the date of Optionee’s death or termination due to Disability or becomes vested and exercisable pursuant to this Section 2.2(a), the Option shall terminate as of the date of Optionee’s
termination of employment. 

  
 1 

 (b) Termination by the Company Other than for Cause, Death or Disability or by
Optionee. If Optionee’s employment with the Company is terminated (i) by the Company for any reason other than for Cause, death or Disability or (ii) by the Optionee by reason of the Optionee’s resignation from employment for
any reason, the Option, to the extent vested on the effective date of such termination of employment, may thereafter be exercised by Optionee until and including the earlier to occur of (i) the date which is ninety (90) days after the date
of such termination of employment and (ii) the Expiration Date. 
 (c) Termination by Company for Cause. If
Optionee’s employment with the Company terminates by reason of the Company’s termination of Optionee’s employment for Cause, then the Option, whether or not vested, shall terminate immediately upon such termination of employment.

 (d) Change in Control. In the event of a Change in Control, the Option, to the extent it is then outstanding, shall
become fully vested and be subject to Section 5.8 of the Plan. 
 (e) Termination of Option During Blackout Period.
If the Option shall expire under Section 2.2(a) or Section 2.2(b) during any period when the Optionee is prohibited from trading in securities of the Company pursuant to the Company’s insider trading policy or other
policy of the Company or during a period when the exercise of the Option would violate applicable securities laws (each, a “Blackout Period”), then the period during which the Option is exercisable shall be extended to the date that
is 30 days after the expiration of such Blackout Period. 
 (f) Definitions. 

(i) Cause. For purposes of this Option, “Cause” shall have the meaning set forth in the employment
agreement, if any, between the Optionee and the Company or any of its Subsidiaries, provided that if Optionee is not a party to an employment agreement that contains such definition, then “Cause” shall mean one or more of the
following: (i) Optionee’s refusal (after written notice and reasonable opportunity to cure) to perform duties properly assigned which are consistent with the scope and nature of Optionee’s position; (ii) Optionee’s
commission of an act materially and demonstrably detrimental to the financial condition and/or goodwill of the Company or any of its Subsidiaries, which act constitutes gross negligence or willful misconduct in the performance of duties to the
Company or any of its Subsidiaries; (iii) Optionee’s commission of any theft, fraud, act of dishonesty or breach of trust resulting in or intended to result in material personal gain or enrichment of Optionee at the direct or indirect
expense of the Company or any of its Subsidiaries; (iv) Optionee’s conviction of a felony involving moral turpitude, but specifically excluding any conviction based entirely on vicarious liability; (v) a material violation by Optionee
of any of the Company’s or any of its Subsidiaries’ written policies or the violation by Optionee of any statutory or common law duty of loyalty to the Company or any of its Subsidiaries or affiliates; or (vi) a violation of any
restrictive covenant with respect to non-competition, non-solicitation, confidentiality or protection of trade secrets (or similar provision regarding intellectual property) by which Optionee is bound under any agreement between Optionee and the
Company and its Subsidiaries. No act or failure to act will be 

  
 2 

 
considered “willful” (x) unless it is done, or omitted to be done, by Optionee in bad faith or without reasonable belief that Optionee’s action or omission was in the best
interests of the Company or (y) if it is done, or omitted to be done, in reliance on the informed advice of the Company’s outside counsel or independent accountants or at the express direction of the Board. 

(ii) Disability. For purpose of this Option, “Disability” shall have the meaning set forth in the
employment agreement, if any, between the Optionee and the Company or any of its Subsidiaries, provided that if Optionee is not a party to an employment agreement that contains such definition, then “Disability” shall mean
Optionee’s inability, due to illness, accident, injury, physical or mental incapacity or other disability, to carry out effectively Optionee’s duties and obligations to the Company or any of its Subsidiaries or, if applicable based on
Optionee’s position, to participate effectively and actively in the management of the Company or any of its Subsidiaries for a period of at least 90 consecutive days or for shorter periods aggregating at least 120 days (whether or not
consecutive) during any twelve month period, as determined in the reasonable judgment of the Board. A Disability shall be deemed to have occurred on the date that either Optionee or Optionee’s personal representative or legal guardian, on the
one hand, or the Company, on the other hand, provides notice to the other party of the satisfaction of each of the requirements to constitute a Disability set forth above or on such other date as the parties shall mutually agree. 

2.3. Method of Exercise. Subject to the limitations set forth in this Agreement, the Option, to the extent vested, may be
exercised by Optionee (a) by delivering to the Company an exercise notice in the form prescribed by the Company specifying the number of whole shares of Common Stock to be purchased and by accompanying such notice with payment therefor in full
(or by arranging for such payment to the Company’s satisfaction) either (i) in cash, (ii) to the extent permitted by the Company (or, if the Optionee is subject to Section 16 of the Exchange Act, the Committee), by delivery to
the Company (either actual delivery or by attestation procedures established by the Company) of shares of Common Stock having an aggregate Fair Market Value, determined as of the date of exercise, equal to the aggregate purchase price payable
pursuant to the Option by reason of such exercise, (iii) to the extent permitted by the Company (or, if the Optionee is subject to Section 16 of the Exchange Act, the Committee), by authorizing the Company to withhold whole shares of
Common Stock which would otherwise be delivered having an aggregate Fair Market Value, determined as of the date of exercise, equal to the amount necessary to satisfy such obligation, (iv) except as may be prohibited by applicable law, in cash
by a broker-dealer acceptable to the Company to whom Optionee has submitted an irrevocable notice of exercise or (v) by a combination of (i), (ii) and (iii), and (b) by executing such documents as the Company may reasonably request.
No share of Common Stock or certificate representing a share of Common Stock shall be issued or delivered until the full purchase price therefor and any withholding taxes thereon, as described in Section 6.1, have been paid. 

2.4. Termination of Option. In no event may the Option be exercised after it terminates as set forth in this
Section 2.4. The Option shall terminate, to the extent not earlier terminated pursuant to Section 2.2 or exercised pursuant to Section 2.3, on the Expiration Date. Upon the termination of the Option, the Option
and all rights hereunder shall immediately become null and void. 

  
 3 

 3. Clawback of Proceeds. 

3.1. Clawback of Proceeds. If Optionee violates any agreement between Optionee and the Company or its Subsidiaries with respect to
non-competition, non-solicitation, confidentiality or protection of trade secrets (or similar provision regarding intellectual property), including Section 5 of this Agreement: (i) the Option shall be forfeited and (ii) the
Optionee shall immediately remit a cash payment to the Company equal to the difference between (A) the Fair Market Value of a share of Common Stock on the date on which the Company first became aware of such violation or the date of
Optionee’s termination of employment, whichever is greater, and (B) the per share Exercise Price, multiplied by (y) the number of shares of Common Stock purchased pursuant to the exercise of the Option. The remedy provided by this
Section 3 shall terminate at such time as the Institutional Investors (as defined below) collectively hold less than 10% of the number of shares of Common Stock held by the Institutional Investors as a result of the Distribution (as
defined below). In addition, the remedy provided by this Section 3 shall be in addition to and not in lieu of any rights or remedies which the Company may have against the Optionee in respect of a breach by the Optionee of any duty or
obligation to the Company. 
 3.2. Right of Setoff. The Optionee agrees that by accepting the Award Notice the Optionee
authorizes the Company and its affiliates to deduct any amount or amounts owed by the Optionee pursuant to this Section 3 from any amounts payable by or on behalf of the Company or any affiliate to the Optionee, including, without
limitation, any amount payable to the Optionee as salary, wages, vacation pay, bonus or the settlement of the Option 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 Optionee shall not constitute a waiver of this right of setoff with respect to any other amount payable to the Optionee or any other remedy. 

3.3. Definitions. For purposes of this Section 3, the following terms shall have the following meanings: 

(a) “Competitive Activity” means Optionee becoming employed by, performing services for, or otherwise becoming
associated with (as an employee, officer, director, manager, partner or consultant or member, stockholder or investor owning more than a 2% interest or other similar role) a Competitor (as defined below) of the Company. 

(b) “Distribution” means the distribution of shares of Common Stock by CDW Holdings LLC, a Delaware limited liability
company, to its members immediately prior to the pricing of the IPO. 
 (c) “Institutional Investors” means,
collectively, Madison Dearborn Capital Partners V-A, L.P., a Delaware limited partnership, Madison Dearborn Capital Partners V-C, L.P., a Delaware limited partnership, Madison Dearborn Capital Partners V Executive-A, L.P., a Delaware limited

 4. Transfer Restrictions and Investment Representations. 

4.1. Nontransferability of Option. The Option may not be transferred by Optionee 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, (i) during Optionee’s lifetime the Option is exercisable only by
Optionee or Optionee’s legal representative, guardian or similar person and (ii) the Option 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, assign, pledge, hypothecate, encumber or otherwise dispose of the Option, the Option and all rights hereunder shall immediately become null and void.

 4.2. Investment Representation. Optionee hereby represents and covenants that (a) any shares of Common Stock
purchased upon exercise of the Option will be purchased for investment and not with a view to the distribution thereof within the meaning of the Securities Act of 1933, as amended (the “Securities Act”), unless such purchase has
been registered under the Securities Act and any applicable state securities laws; (b) any subsequent sale of any such shares shall be made either pursuant to an effective registration statement under 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 (c) if requested by the Company, Optionee shall submit a written statement, in a form satisfactory to the Company, to
the effect that such representation (x) is true and correct as of the date of any purchase of any shares hereunder or (y) is true and correct as of the date of any sale of any such shares, as applicable. As a further condition precedent to
any exercise of the Option, Optionee shall comply with all regulations and requirements of any regulatory authority having control of or supervision over the issuance or delivery of the shares and, in connection therewith, shall execute any
documents which the Board or the Committee shall in its sole discretion deem necessary or advisable. 
 5. Noncompete,
Nonsolicitation and Confidentiality. Optionee acknowledges that in the course of his or her employment with or provision of services to the Company or its Subsidiaries, Optionee has and will become familiar with trade secrets and other
confidential information concerning the Company and its Subsidiaries and that Optionee’s services will be of special, unique and extraordinary value to the Company and its Subsidiaries. Optionee also acknowledges that the Company’s
Confidential Information (as this and other terms used herein are defined below) will retain continuing vitality throughout and beyond the Noncompetition Period, and that should Optionee leave the Company and work for a Competitor during the
Noncompetition Period, it would be highly likely, if not inevitable, that Optionee would use or disclose the Company’s Confidential Information. For these and other reasons, Optionee agrees and acknowledges that the restrictions in this
Agreement are reasonable and necessary to protect the Company’s legitimate business interests. 

  
 5 

 5.1. Noncompete. In consideration for the issuance of the Option and other good and
valuable consideration, Optionee agrees not to become employed by, perform services for, form, develop, or otherwise become associated with (as an employee, officer, director, manager, partner or consultant or member, stockholder or investor owning
more than a 2% interest or other similar role) a Competitor of the Company or any of its Subsidiaries at any time during Optionee’s employment with or service to the Company or any of its Subsidiaries or for twelve months after the termination
of Optionee’s employment with or service to the Company or any of its Subsidiaries (the “Noncompetition Period”). For purposes of this Section 5, “Competitor” shall mean any Person conducting or
planning to conduct a business similar to and in competition with any business conducted or planned by the Company or any of its Subsidiaries in any geographic area in which the Company or any of its Subsidiaries is conducting such business or plans
to conduct such business as of the date of termination of Optionee’s employment with or services to the Company or its Subsidiaries, if Optionee, while employed by or providing services to the Company or any of its Subsidiaries, was involved in
such business or had knowledge of the operations of such business or received or was otherwise in possession of Confidential Information as defined in Section 5.6 regarding such business. For purposes of illustration only, the parties
agree that each of the corporations, other enterprises or Persons set forth on Schedule I attached hereto is a “Competitor” of the Company and its Subsidiaries as of the date hereof, it being acknowledged and agreed that
(x) such list is only representative of the Company’s current Competitors but not exhaustive and is not intended to include all of the Company’s or its Subsidiaries’ current Competitors and (y) other Persons could become
Competitors of the Company or its Subsidiaries at a future date. 
 5.2. Nonsolicitation. Optionee further agrees that
during the Noncompetition Period Optionee shall not (i) in any manner, directly or indirectly, solicit any CDW Employee or induce or attempt to induce any CDW Employee to terminate or abandon his or her employment for any purpose whatsoever or
(ii) on behalf of any Competitor, call on, service, solicit or otherwise do business with any CDW Vendor or CDW Customer. 

5.3. Exceptions. Nothing in this Section 5 shall prohibit Optionee from being (i) a stockholder in a mutual fund
or a diversified investment company or (ii) an owner of not more than two percent of the outstanding stock of any class of a corporation, any securities of which are publicly traded, so long as Optionee has no active participation in the
business of such corporation. 
 5.4. Extension. Because the protection of the Company’s Confidential Information
requires that Optionee not perform the activities described in Sections 5.1 and 5.2 for the full Noncompetition Period, Optionee agrees that the Noncompetition Period provided in Section 5 shall be extended for any time
during which Optionee breaches this Agreement, such that Optionee does not perform the proscribed activities for a time period equal to the full amount of time provided in Section 5. 

5.5. Reformation. If, at any time of enforcement of this Section 5, a court or an arbitrator holds that the
restrictions stated herein are unreasonable under circumstances then existing, the parties hereto agree that the maximum period, scope or geographical area reasonable under such circumstances shall be substituted for the stated period, scope or area
and that the court or arbitrator shall be allowed to revise the restrictions contained herein to cover the maximum period, scope and area permitted by law. This Agreement shall not authorize a court or arbitrator to increase or broaden any of the
restrictions in this Section 5. 

  
 6 

 5.6. Confidentiality. Other than as required in the ordinary course of
Optionee’s employment by the Company or its Subsidiaries, and except as specifically authorized by the Board or Optionee’s direct supervisor, Optionee shall not at any time make use of or disclose, directly or indirectly, any
(i) trade secret or other confidential or secret information of the Company or of any of its Subsidiaries or (ii) other technical, business, proprietary or financial information of the Company or of any of its Subsidiaries not available to
the public generally or to Competitors (“Confidential Information”), except to the extent that such Confidential Information (a) becomes a matter of public record or is published in a newspaper, magazine or other periodical or
on electronic or other media available to the general public, other than as a result of any act or omission by Optionee or (b) is required to be disclosed by any law, regulation or order of any court or regulatory commission, department or
agency, provided that Optionee gives prompt notice of such requirement to the Company to enable the Company to seek an appropriate protective order. Promptly following the termination of Optionee’s employment or service with the Company or any
of its Subsidiaries, Optionee shall surrender to the Company all records, memoranda, notes, plans, reports, computer tapes and software and other documents and data which constitute Confidential Information which Optionee may then possess or have
under his/her control (together with all copies thereof). 
 5.7. Acknowledgements. Optionee acknowledges that the
provisions of this Section 5 are in addition to, and not in limitation of, any obligation of Optionee under the terms of any employment or other agreement with the Company or any Subsidiary, and in consideration of (i) employment by
the Company or its Subsidiaries or retention to provide services to the Company and its Subsidiaries and (ii) additional good and valuable consideration as set forth in this Agreement. In addition, Optionee agrees and acknowledges that the
restrictions contained in this Section 5 do not preclude Optionee from earning a livelihood, nor do they unreasonably impose limitations on Optionee’s ability to earn a living. In addition, Optionee acknowledges (i) that the
business of the Company or its Subsidiaries will be conducted throughout the United States, (ii) notwithstanding the state of incorporation or principal office of the Company or its Subsidiaries, or any of their respective executives or
employees (including Optionee), it is expected that the Company or its Subsidiaries will have business activities and have valuable business relationships within its industry throughout the United States, and (iii) as part of Optionee’s
responsibilities, Optionee will be conducting business throughout the United States in furtherance of the Company’s business and its relationships. Optionee agrees and acknowledges that the potential harm to the Company and its Subsidiaries of
the non-enforcement of this Section 5 outweighs any potential harm to Optionee of its enforcement by injunction or otherwise. Optionee acknowledges that Optionee has carefully read this Agreement and has given careful consideration to
the restraints imposed upon Optionee by this Agreement, and is in full accord as to their necessity for the reasonable and proper protection of confidential and proprietary information of the Company, its Subsidiaries and Affiliates now existing or
to be developed in the future. Optionee expressly acknowledges and agrees that each and every restraint imposed by this Agreement is reasonable with respect to subject matter, time period and geographical scope. 

  
 7 

 5.8. Definitions. For purposes of this Section 5 the following terms
shall have the following meanings: 
 (a) “CDW Customer” means (i) any person or entity that purchased any
products or services from the Company or any of its Subsidiaries or affiliates at any time within a two year period prior to Optionee’s termination (for whatever reason) from the Company or (ii) any person or entity with respect to whom,
at any time during the one year period prior to Optionee’s termination (for whatever reason) from the Company, Optionee submitted or assisted in the development or submission of a presentation or proposal of any kind on behalf of the Company or
any of its Subsidiaries or affiliates, acquired or had access to any Confidential Information or had contact with as a result of Optionee’s employment with the Company. 
 (b) “CDW Employee” means any person who was an officer, manager-level or other key employee or any material group of employees of the Company or any of its Subsidiaries or affiliates
either (i) at any time within three months of the prohibited contact; or (ii) at any time within three months of Optionee’s termination (for whatever reason) from the Company. 

(c) “CDW Vendor” means any person or entity that provided goods or services to the Company or any of its Subsidiaries or
otherwise did business with the Company or any of its Subsidiaries at any time within a two-year period prior to Optionee’s termination (for whatever reason) from the Company. 

(d) “Person” means any individual, partnership, corporation, association, joint stock company, trust, joint venture,
limited liability company, unincorporated organization, governmental entity or department, agency or political subdivision thereof. 
 5.9. Remedies. The parties hereto shall be entitled to enforce their respective rights under this Agreement specifically, to recover damages by reason of any breach of any provision of this
Agreement, and to exercise all other rights existing in their favor. The parties hereto acknowledge and agree that money damages would not be an adequate remedy for any breach of the provisions of this Agreement and that any party hereto may, in
their sole discretion, apply to any court of law or equity of competent jurisdiction for specific performance and/or injunctive relief (without posting bond or other security) in order to enforce or prevent any violation of the provisions of this
Agreement. 
 6. Additional Terms and Conditions. 

6.1. Withholding Taxes. (a) As a condition precedent to the issuance of Common Stock following the exercise of the Option,
Optionee shall, upon request by the Company, pay to the Company in addition to the purchase price of the shares, such amount as the Company may be required, under all applicable federal, state, local or other laws or regulations, to withhold and pay
over as income or other withholding taxes (the “Required Tax Payments”) with respect to such exercise of the Option. If Optionee shall fail to advance the Required Tax Payments after request by the Company, the Company may, in its
discretion, deduct any Required Tax Payments from any amount then or thereafter payable by the Company to Optionee. 

  
 8 

 (b) Optionee 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; (ii) to the extent permitted by the Company (or, if the Optionee is subject to Section 16 of the Exchange Act, 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) to the extent permitted by the Company (or, if the Optionee is subject to Section 16 of the Exchange Act, the Committee), authorizing the Company to withhold whole shares of Common
Stock which would otherwise be delivered to Optionee upon exercise of the Option having an aggregate Fair Market Value, determined as of the Tax Date, equal to the Required Tax Payments; (iv) except as may be prohibited by applicable law, a
cash payment by a broker-dealer acceptable to the Company to whom Optionee has submitted an irrevocable notice of exercise or (v) 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 minimum amount of the Required Tax Payments; provided, however, that if a fraction of a share of Common Stock would be required to satisfy the minimum amount of the Required Tax Payments, then the
