                                 PROXY STATEMENT

                          ANNUAL MEETING - MAY 22, 2002



Information Regarding Proxies

         This Proxy Statement is furnished in connection with the solicitation
of proxies by the Board of Directors of CDW Computer Centers, Inc. (the
"Company"), to be voted at the Annual Meeting of Shareholders on Wednesday, May
22, 2002 (the "Annual Meeting of Shareholders" or "Annual Meeting") and at any
and all adjournments thereof.

         This Proxy Statement and the accompanying proxy card are first being
mailed to shareholders on or about April 18, 2002. The cost of solicitation of
proxies will be borne by the Company. In addition to solicitation by mail, some
of the directors, officers and regular employees of the Company may, without
extra compensation, solicit proxies by telephone, e-mail, facsimile, telegraph
and personal interview. Arrangements will be made with brokerage houses,
custodians, nominees and other fiduciaries to send proxy material to their
principals and the Company will reimburse them for postage and clerical expense
in doing so.

         Votes cast by proxy or in person at the Annual Meeting of Shareholders
will be tabulated by the election inspectors appointed for the meeting and they
will determine whether or not a quorum is present. The election inspectors will
treat abstentions as shares that are present and entitled to vote for purposes
of determining the presence of a quorum but as not-voted for purposes of
determining the approval of any matter submitted to the shareholders for a vote.
Accordingly, an abstention will have the same effect as a vote against such
matter. Shares as to which proxies have been executed will be voted as specified
in the proxies. If no specification is made in an otherwise properly executed
proxy, the shares will be voted "FOR" the election of management's nominees as
directors and "FOR" the other proposals listed. If a broker indicates on the
proxy that it does not have discretionary authority as to certain shares to vote
on a particular matter, those shares will not be considered as present and
entitled to vote with respect to that matter.

         Proxies may be revoked at any time prior to the exercise thereof by
filing with the Secretary of the Company, at the Company's executive offices, a
written revocation or a duly executed proxy bearing a later date. The executive
offices of the Company are located at 200 North Milwaukee Avenue, Vernon Hills,
Illinois 60061.

            Unless otherwise indicated, all information provided herein is given
as of the date hereof.


                                       1






Voting Securities

         The securities of the Company entitled to be voted at the meeting
consist of shares of its Common Stock, $0.01 par value ("Common Stock"). Each
share of Common Stock is entitled to one vote on all matters. On April 5, 2002
(the "Record Date"), 85,949,156 shares of Common Stock were issued and
outstanding. In addition, 3,047,500 shares are held in Treasury by the Company
and are deemed issued but not outstanding.

         Only shareholders of record at the close of business on the Record Date
will be entitled to receive notice of and to vote at the meeting. There are no
cumulative voting rights. A properly executed proxy marked "WITHHELD" with
respect to the election of one or more directors will not be voted with respect
to the director or directors indicated, although it will be counted for purposes
of determining the existence of a quorum.

         Assuming a quorum is present in person or by proxy, the affirmative
vote of a majority of the votes represented in person or by proxy and entitled
to vote is required for election of the directors and ratification of the
independent accountant.

Shareholder Proposals

         Any shareholder desirous of including any proposal in the Company's
proxy soliciting material for the next regularly scheduled Annual Meeting of
Shareholders (for the year ending December 31, 2002) must submit his or her
proposal, in writing, directed to the Company's executive offices not later than
December 19, 2002. Any such proposal must comply with Rule 14a-8 of Regulation
14A of the proxy rules of the Securities Exchange Act of 1934, as amended, in
order for such proposal to be considered for inclusion in the 2003 Proxy
Statement.

         In addition, pursuant to the rules and regulations of the Securities
and Exchange Commission, at the Company's 2003 Annual Meeting of Shareholders
the proxy holders appointed by the Company may exercise discretionary authority
when voting on a shareholder proposal properly presented at such meeting that is
not included in the Company's proxy statement for such meeting if such proposal
is received by the Company after March 4, 2003. If notice of a shareholder
proposal is received by the Company on or prior to such date and such proposal
is properly presented at the 2003 Annual Meeting but not included in the
Company's proxy statement for such meeting, the proxy holders appointed by the
Company may exercise discretionary authority if in such proxy statement the
Company advises shareholders of the nature of such proposal and how the proxy
holders appointed by the Company intend to vote on such proposal, unless the
shareholder submitting such proposal satisfies certain requirements of the
Securities and Exchange Commission, including the mailing of a separate proxy
statement to the Company's shareholders.

         All shareholder proposals should be directed to the Secretary of the
Company.

Security Ownership

         The following table sets forth certain information regarding the
beneficial ownership of the Company's Common Stock at March 31, 2002, except

Section 16(a) Beneficial Ownership Reporting Compliance

         Section 16(a) of the Securities Exchange Act of 1934 and regulations of
the Securities and Exchange Commission thereunder require the Company's
executive officers and directors and persons who own more than ten percent of
the Company's stock, as well as certain affiliates of such persons, to file
initial reports of ownership and changes in ownership with the Securities and
Exchange Commission and The Nasdaq Stock Market. Executive officers, directors
and persons owning more than ten percent of the Company's stock are required by
the Securities and Exchange Commission regulations to furnish the Company with
copies of all Section 16(a) forms they file. Based solely on its review of the
copies of such forms received by it and written representations that no other
reports were required for those persons, the Company believes that, except as
noted below, during the year ended December 31, 2001, all persons subject to
Section 16(a) were in compliance with all Section 16(a) filing requirements.
Brian Williams inadvertently failed to file a Form 5 to report the donation of

MPK Stock Option Plan

         At the time of the Company's initial public offering, Mr. Krasny
established the MPK Stock Option Plan pursuant to which he granted to Messrs.
Zeman and Kass and a former employee of the Company non-forfeitable options to
purchase in the aggregate 16,573,500 shares of Common Stock owned by him. As of
March 31, 2002, options to acquire an aggregate of 1,493,240 shares of common
stock remain outstanding, of which Mr. Zeman holds options to acquire 958,864
shares and Mr. Kass holds options to acquire 534,376 shares. These options are
non-forfeitable and become exercisable during the employment of such individual
at the rate of 5% per year upon each of the first four anniversaries of the
grant and an additional 15% on each anniversary date thereafter until all
options are exercisable. Additional shares may be exercised proportionately to
any shares sold by Mr. Krasny from his holdings. The options may be exercised at
a price of $0.004175 per share. The MPK Stock Option Plan provides that should
Messrs. Zeman or Kass terminate his employment with the Company, all options
become exercisable and such individual will be required to exercise his options
at the option exercise price within six months of the date of termination. The
MPK Stock Option Plan, which is wholly funded from shares of Common Stock owned
by Mr. Krasny, does not result in a cash payment from plan participants to the
Company or increase the number of outstanding shares of Common Stock.

Employment Related Agreements

         Messrs. Krasny, Zeman and Kass

         The Company entered into Employment and Non-Competition Agreements with
Messrs. Krasny, Zeman and Kass that became effective upon the consummation of
the Company's initial public offering in 1993. The initial base salaries of
Messrs. Krasny, Zeman and Kass were $200,000, $175,000 and $175,000,
respectively, to be adjusted in each case annually in accordance with the
Consumer Price Index. In accordance with the terms of each Agreement, employment
is terminable with or without Cause. Each Agreement contains a non-competition
restriction prohibiting the executive from undertaking certain competitive
activities for a two-year period after the date his employment with the Company
ceases. Effective May 23, 2001, Mr. Krasny resigned, thereby terminating his
employment with the Company. Mr. Krasny presently serves the Company solely in
the capacity of a director. Mr. Zeman's and Mr. Kass' base salaries have been
adjusted to reflect their current roles with the company. See "Management" and
"Executive Compensation".

         Mr. Edwardson

         The Company entered into an employment agreement with John A. Edwardson
on January 28, 2001. The agreement provides for Mr. Edwardson to serve as Chief
Executive Officer of the Company until the fifth anniversary of the agreement,
subject thereafter to annual renewal provisions. Pursuant to the employment
agreement, during the term of his employment with the Company, Mr. Edwardson
will be nominated for election as a member of the Board of Directors and, if so
elected will be appointed Chairman of the Board. Mr. Edwardson receives an
annual base salary of $600,000, subject to annual review by the Compensation
Committee, and participates in the Company's Senior Management Incentive Plan.
Incentive bonuses under the Senior Management Incentive Plan are based on
objective criteria established and approved by the Compensation Committee of the
Board each year.

         In accordance with the employment agreement, Mr. Edwardson received
non-qualified stock options to purchase 1,600,000 shares of Common Stock under
the Company's 2000 Incentive Stock Option Plan. The exercise price of these
options is $36.625, the fair market value of the Company's Common Stock on the
date of grant. One-fifth of these options will vest on each of the first five
anniversaries of the employment agreement. In addition, Mr. Edwardson was
granted a restricted stock award of 100,000 shares of Common Stock that will
vest in equal annual installments on the first four anniversaries of the date of
grant. If Mr. Edwardson's employment is terminated by the Company without cause
or by Mr. Edwardson for Good Reason, one-half of any unexercisable options will
immediately become exercisable and one-half of the portion of the restricted
stock award that is not vested will immediately become vested. Beginning with
the 2002 fiscal year, Mr. Edwardson will be granted annually non-qualified stock
options to purchase 150,000 shares of Common Stock, which options will be
subject to terms substantially similar to the terms of the options described
above. With respect to his 2002 grant, Mr. Edwardson has indicated that he will
only accept options for the purchase of 100,000 shares in order to make options
for an additional 50,000 shares available to the Company's coworkers.

         If the employment agreement is terminated by the Company without
Cause or by Mr. Edwardson for Good Reason, the Company will be required, among
other things, to make a lump sum cash payment to Mr. Edwardson equal to two
times the sum of his annual base salary and his average annual bonus and to
pay certain accrued obligations through the date of termination. For purposes
of the employment agreement, Good Reason includes the failure to elect Mr.
Edwardson as Chairman of the Board immediately following each annual meeting
of shareholders during the employment period. Such election is possible only
if the shareholders re-elect Mr. Edwardson as a member of the Board, and if he
is not so re-elected, he will be entitled to terminate the employment
agreement for Good Reason and receive the payments described above. The
agreement also contains standard non-competition and non-solicitation
covenants that survive during the term of the agreement and for a period of
two years thereafter.

         The Company has also entered into a transitional compensation
agreement with Mr. Edwardson. In the event of a Change of Control (as defined
in the transitional compensation agreement), the employment relationship
between



                                      13




the Company and Mr. Edwardson will be exclusively governed by the transitional
compensation agreement. Upon a Change in Control, all stock options,
restricted stock and other equity awards to Mr. Edwardson that are not
otherwise vested will vest in full, and all options will remain exercisable
for the period provided in the applicable award agreement. If, following a
Change of Control, there is a Qualifying Termination (as defined in the
transitional compensation agreement), Mr. Edwardson will receive the following
benefits in lieu of benefits under the employment agreement: (i) payment in a
lump sum of an amount equal to 300% of his base salary and his average annual
bonus, (ii) prorated annual incentive bonus (based on the target bonus under
the Incentive Plan) through the date of termination, (iii) payment of all
accrued obligations through the date of termination in a lump sum and (iv) the
continuation of all welfare benefits and senior executive perquisites for a
period of two years or an equivalent lump sum cash payment. In the event that
such payments and benefits subject Mr. Edwardson to the excise tax imposed by
Section 4999 of the Internal Revenue Code of 1986, as amended, Mr. Edwardson
would be entitled to receive a "gross-up" payment, unless his net after-tax
benefit resulting from such gross-up payment, as compared to a reduction of
such payments and benefits so that no excise tax is incurred, is less than
$100,000.

Certain Transactions

         On February 2, 2001, the Company, as part of its publicly announced
share repurchase program, entered into an agreement to purchase 1,181,818 shares
of Common Stock from Mr. Zeman and an agreement to purchase 318,182 shares of
Common Stock from Mr. Kass. The per-share price for both sales was $38.423,
resulting in a total payment to Mr. Zeman of $45,408,993.01 and a total payment
to Mr. Kass of $12,225,506.99. The per-share price was determined by subtracting
$0.015 per share from the closing price on the day of the agreements.

         In connection with these purchases, on February 5, 2001, the Company
entered into a registration rights agreement with each of Mr. Zeman and Mr. Kass
(the "Registration Rights Agreements"). The Registration Rights Agreements give
each of Mr. Zeman and Mr. Kass the right to demand (a "Registration Demand"),
one time in each of calendar year 2001, 2002 and 2003, that the Company register
some or all of the shares of Common Stock held by him at such time or to be
acquired by him pursuant to the exercise of options under the MPK Stock Option
Plan. The Company will have the option, when a Registration Demand is presented
to it, to either (i) purchase, at a per share price equal to $0.015 less than
the then-current trading price, the shares subject to such Registration Demand,
(ii) register such shares on a "shelf" registration statement pursuant to Rule
415 under the Securities Act of 1933, as amended (the "Securities Act"), or
(iii) register such shares on an registration statement under the Securities Act
and cooperate with Mr. Zeman or Mr. Kass, as applicable, in developing and
conducting an organized marketing campaign and "road show" relating to such
registration statement. The Registration Rights Agreements contain customary
conditions and limitations, including those relating to blackouts resulting from
material non-public information which the Company should not be forced to
disclose prematurely and to giving priority to Company financings.

         On June 26, 2001, the Company filed a registration statement to
facilitate the sale by Mr. Krasny, Mr. Zeman and Mr. Kass of shares of our
Common Stock. The underwritten sale, which was completed on August 14, 2001, was
for a total of 10,562,500 shares, of which Mr. Krasny and entities related to
Mr. Krasny sold 7,810,768, Mr. Zeman sold 2,315,732 and Mr. Kass sold 436,000.
The shares sold by Mr. Zeman and Mr. Kass were acquired by them from Mr. Krasny
upon the exercise of options granted to them by Mr. Krasny under the MPK Stock
Option Plan. The Company did not receive any of the proceeds of the offering and
there was no increase in the number of shares of Common Stock outstanding. The
Company did not incur any expenses in connection with the offering, however the
Company executed an underwriting agreement pursuant to which it agreed to
certain indemnities, including under the securities laws.

         On January 25, 2002, the Company received a Registration Demand from
Mr. Zeman for 2,000,000 shares of Common Stock. On March 11, 2002, the Company
filed a "shelf" registration statement pursuant to Rule 415 under the Securities
Act covering the 2,000,000 shares of Common Stock. On March 26, 2002, Mr. Zeman
exercised options under the MPK Stock Option Plan and sold the shares in an
underwritten offering. Mr. Zeman received proceeds of $47.70 per share, which is
net of the underwriting discount. The company expects to incur approximately
$41,000 in expenses relating to the registration statement and the Company
executed an underwriting agreement pursuant to which it agreed to certain
indemnities, including under the securities laws.


                                      14




         The Company has agreed to pay the costs associated with an executive
assistant for Mr. Krasny during the two-year period following his resignation
effective May 23, 2001. In 2001, the Company paid approximately $67,500 under
this arrangement.

Report of the Audit Committee

         The Audit Committee oversees the Company's financial reporting process
on behalf of the Board of Directors. The Audit Committee consists of three
independent directors. Its duties and responsibilities are set forth in a
written charter (the "Audit Committee Charter") adopted by the Board in April
2001. The Audit Committee Charter was attached as Exhibit A to the Company's
proxy statement for last year's Annual Meeting of Shareholders, which was filed
with the Securities and Exchange Commission on April 11, 2001 and mailed to
shareholders shortly thereafter.

         In the course of fulfilling its responsibilities during fiscal year
2001, the audit committee has:

o  reviewed and discussed with management the audited financial statements for
   the year ended December 31, 2001;

o  discussed with representatives of PricewaterhouseCoopers LLP (the
   "Independent Auditor") the matters required to be discussed by Statement on
   Auditing Standards No. 61, Communication with Audit Committees, as amended;

o  received the written disclosures and the letter from the Independent
   Auditor required by Independence Standards Board Standard No. 1,
   Independence Discussions with Audit Committees, as amended;

o  discussed with the Independent Auditor its independence from the Company
   and management; and

o  considered whether the provision by the Independent Auditor of non-audit
   services is compatible with maintaining the Independent Auditor's
   independence.

         Based on the foregoing, the Audit Committee recommended to the Board of
Directors that the audited financial statements referred to above be included in
the Company's Annual Report on Form 10-K for the fiscal year ended December 31,
2001.

Report of the Compensation and Stock Option Committee

The Compensation and Stock Option Committee (the "Compensation Committee") is
currently comprised of three independent directors.

Compensation Policy

         General. The Company's executive compensation program is designed to
advance the interests of the Company by attracting, motivating and retaining
well-qualified executives, managers and other key employees, and to align
their interests with those of the Company's shareholders by providing them
with performance-based incentives linked to corporate performance factors. The
three primary components of the Company's executive compensation program are:

         (i)    base salary;

         (ii)   annual incentive awards; and

         (iii)  long-term incentive awards in the form of stock option grants.

         Over the course of 2001, the Committee met several times with the
Company's staff and representatives of a nationally recognized consulting firm
to review key aspects of the Company's executive compensation plan. The purpose
of the review was to ensure that the Company's executive compensation program
continued to meet the talent-management needs of the organization and was
consistent with the Company's strategic vision.

         As a result of this review, a number of changes were made to executive
programs. In addition to general consistency with the Company's strategic
vision, the changes implemented in 2001 and early 2002 helped the programs
better reflect the following defining characteristics:

         o      Focus on pay-for-performance

         o      Capable of delivering highly differentiated rewards

         o      Externally competitive and market-based

         o      Flexible and balanced in performance orientation

         o      Well integrated with other coworker programs to reinforce
                commonality of purpose

         o      Straightforward, simple and well communicated

         o      Anchored in a consistent and logical framework

         o      Oriented toward delivery of an effective total compensation
                package

         Specific changes will be implemented in 2002. In general, the changes
implemented as a result of the review will reflect more clearly articulated
internal and external objectives for each element of total executive
compensation. In addition, the total compensation profile for executive officers
will be changed to render it more consistent with the Company's objectives,
including retention of key executives. Changes to underlying programs for 2002
reflect the desired compensation profile.

         Base Salary. Base salaries for Named Officers of the Company reflect
their level of experience, past and expected future performance and market
conditions. The base salary of each executive also is set at a level such that
the greater portion of their total compensation is dependent upon Company
performance.

         The base salary of Mr. Edwardson was initially established by the terms
of his employment agreement in 2001 and is subject to periodic adjustments by
the Committee. Annual adjustments in the base salaries of the other


                                      17




Named Officers reflect several factors, including changes in the United States
Consumer Price Index, as well as merit increases, where applicable.

         As part of the aforementioned executive compensation review, the
Committee outlined a two year transition toward a total compensation profile for
executives that is more consistent with the Company's talent-management
objectives and goal of retaining key executives.

         One aspect of this transition is the development of market-rate base
pay levels for each executive role, targeted at or near the 50th percentile
among comparable incumbents at appropriate peer companies. As part of their
review, the Committee considered competitive data showing the Company's position
relative to targeted levels at peer companies, and evaluated 2002 base pay
increases for executive officers on that basis.

         Annual Incentive Awards. The annual incentive element of the Company's
executive compensation program is pursuant to the Company's Senior Management
Incentive Plan. Awards for 2001 reflect the Company's performance relative to
goals relating to growth in net income from operations.

         For 2002, funding of awards under the plan for executive officers will
continue to be based predominantly upon achievement of pre-established goals
related to income from operations. The Senior Management Incentive Plan has been
designed to provide opportunities for awards that will place executive total
cash compensation at or near the 75th percentile among a range of peer
companies, provided the Company delivers superior increases in operating income
levels relative to its key peers. Award opportunities for individual executive
officers have been set accordingly.

         Following the conclusion of the aforementioned executive compensation
review, the Committee noted their desire to incorporate greater emphasis on
individual accountability for business results, particularly among the senior
executive group. Accordingly, starting in 2002, final awards under the Senior
Management Incentive Plan will also take into account individual performance
relative to pre-established goals and objectives, as well as other business and
environmental factors that the Committee deems relevant to attainment of the
Company's overall financial goals and strategic vision.

         In addition to the Senior Management Incentive Plan, the Company's
executives participate in a company-wide management bonus pool. Each Named
Officer, other than Mr. Edwardson, received a $10,000 allocation of the pool for
fiscal year 2001.

         Long-Term Incentive Awards. The long-term incentive element of the
Company's executive compensation program consists of the grant of stock
options to employees, including the Company's executive officers. Stock
options have been granted to the executive officers based upon factors
discussed below either (i) with an exercise price equal to 100% of fair market
value as of the date of grant or (ii) (on a selective basis) in partial
payment of annual incentive awards under the Senior Management Incentive Plan
which have been earned. Stock options that were granted in payment of 2001
annual incentive awards carried an exercise price of $0.01. The number of
stock options granted was determined by dividing the amount of the award by
the difference between the market price of the Common Stock as of the date of
grant and the option exercise price. For the 2002 compensation year, grants
made to the named executive officers and others will have an exercise price
equal to 100% of fair market value as of the date of grant. The Company's
Long-Term Incentive program will be reconfigured to provide opportunities at
or near the 75th percentile among a range of peer companies, underlining the
emphasis on longer-term results that the Committee believes is appropriate for
senior executive team members.




                                      18



Implementation of Compensation Policy

         The Compensation Committee met on January 25, 2001 to review and
certify annual incentive and stock option awards to officers and employees of
the Company relative to performance-based compensation programs in 2000 and to
establish, as necessary, the 2001 base compensation and performance-based
compensation programs for executive officers. The Compensation Committee met on
March 12, 2001 to review and approve the Company's Senior Management Incentive
Plan, including target bonus levels and performance achievement targets. The
Compensation Committee met on January 24, 2002 to discuss various matters,
including the status of 2001 performance-based compensation programs and
approved the formula to be applied for determining the number of options to be
granted to each coworker as of February 1, 2002. Further, the Compensation
Committee reviewed and approved stock option allocations to officers and
employees of the Company, and reviewed and certified annual incentive awards to
officers and employees pursuant to performance-based compensation programs.
There was a special meeting of the Compensation Committee on January 28, 2001 to
review and approve the terms of Mr. Edwardson's employment as Chief Executive
Officer and President of the Company, including the grant of restricted stock
and stock options. There also were special meetings on July 26, September 17 and
October 25, 2001 in the course of undertaking the aforementioned review of
executive compensation.

         Compensation of the Chief Executive Officer. Mr. Krasny's compensation
for 2001 consisted solely of base salary of $93,895 that represented the pro
rata share from January 1, 2001 through the annual meeting on May 23, 2001 of
his annualized base salary of $237,015. Mr. Krasny's annualized base was not
raised in 2001 over 2000.

         Per his contractual agreements for 2001, Mr. Edwardson received base
salary of $546,923, a bonus of $440,000, a restricted stock grant of 100,000
shares, and a stock option grant of 1,600,000 options. Mr. Edwardson's annual
incentive award based upon his participation in the 2001 Senior Management
Incentive Plan was $866,400, of which $433,200 was paid in the form of a stock
option grant for 8,067 shares.

         Section 162(m) of the Internal Revenue Code generally disallows a
federal income tax deduction to public companies for compensation over
$1,000,000 paid to the corporation's chief executive officer and four other most
highly compensated executive officers. Qualified performance-based compensation
will not be subject to the deduction limit if certain requirements are met. The
Company currently intends to structure the performance-based portion of the
compensation of its executive officers in a manner that complies with this
provision so that such amounts will be deductible to the Company.

                      PROPOSAL TO APPROVE AMENDMENT TO THE
                      ------------------------------------
                      CDW 2000 INCENTIVE STOCK OPTION PLAN
                      ------------------------------------

General

         The Board of Directors is proposing for shareholder approval an
amendment to the CDW 2000 Incentive Stock Option Plan, previously approved by
shareholders in May 2000. The CDW 2000 Incentive Stock Option Plan, as Amended
through April 2, 2002 (the "Amended Plan"), was approved by the Board of
Directors on such date, subject to shareholder approval. If the Amended Plan is
not approved by shareholders, the terms of the CDW 2000 Incentive Stock Option
Plan, as originally adopted by the Board of Directors and approved by
shareholders, will remain in effect, and, immediately following the Annual
Meeting, the Board of Directors will grant to each non-employee director a
discretionary option to purchase 12,480 shares of Common Stock, i.e., the stock
option that would have been granted automatically to each non-employee director
on January 2, 2002, in the absence of the proposed amendments described below.

         The purposes of the Amended Plan are to align the interests of the
shareholders of the Company and the recipients of stock options granted under
the Amended Plan and to advance the interests of the Company by attracting,
motivating and retaining well-qualified persons by providing such persons with
performance-related incentives.

Proposed Amendment

         In late 2001, in order to ensure that the Company remains
well-positioned to attract and retain qualified candidates to serve as
non-employee directors of the Company, the Compensation and Stock Option
Committee of the Board of Directors (the "Compensation Committee"), in
consultation with outside compensation consultants, reviewed and assessed the
Company's compensation package for non-employee directors. The Compensation
Committee determined it to be advisable to make the compensation package for
non-employee directors more competitive by increasing the annual cash retainer
fee and changing the equity component of the compensation package and
recommended such changes to the full Board of Directors. To effect the
recommended change in equity compensation, the Board of Directors approved,
subject to shareholder approval, the Amended Plan which provides that (1) each
person who is first elected or first begins to serve as a non-employee director,
other than by reason of termination of employment, on or after the Annual
Meeting will automatically be granted, on the date of such person's initial
election or commencement of service as a non-employee director, an option to
purchase 20,000 shares of Common Stock; and (2) on the date of each annual
meeting of shareholders, commencing with the Annual Meeting, each non-employee
director will be granted an option to purchase 10,000 shares of Common Stock
(which number will be prorated if such non-employee director was first elected
or began to serve as a non-employee director on a date more recent than that of
the previous annual meeting of shareholders). These new provisions will replace
the existing automatic annual grant on the first trading day of each year of
options to purchase a number of whole shares of Common Stock equal to the sum of
12,000 (6,000 shares adjusted for the 2-for-1 stock split on June 21, 2000) plus
the product of 12,000 multiplied by the percentage increase in the Company's
immediately preceding fiscal year's net income over the second immediately
preceding fiscal year's net income. All options granted to non-employee
directors under the existing automatic grant procedure vest in full three years
after the grant date. Under the terms of the Amended Plan, the new
non-discretionary option grants described in clauses (1) and (2) above become
exercisable in 20 percent increments over the five year period following the
date of grant and generally remain exercisable for the three-year period
following termination of service as a non-employee director. The Amended Plan
also permits each non-employee director to elect to receive additional options
in lieu of all or part of his or her annual cash retainer fee.


                                      22




         The proposed amendment does not increase the total number of shares of
Common Stock available under the Amended Plan.

Description of Amended Plan

         The following is a summary of the Amended Plan, which is qualified in
its entirety by reference to the text of the Plan. The Amended Plan is attached
as Exhibit A to this Proxy Statement and incorporated herein by reference.

         Administration. The Compensation Committee will administer the Amended
Plan. Each member of the Compensation Committee is a "Non-Employee Director"
within the meaning of Rule 16b-3 under the Securities Exchange Act of 1934 and
an "outside director" within the meaning of Section 162(m) of the Internal
Revenue Code of 1986, as amended (the "Code").

         The Compensation Committee is authorized to interpret the Amended Plan
and its application and, subject to the terms of the Amended Plan, to establish
rules and regulations as it deems necessary or desirable for the administration
of the Amended Plan. The Compensation Committee may impose, incidental to the
grant of a stock option thereunder, conditions with respect to the grant, such
as limiting competitive employment or other activities. All such
interpretations, rules, regulations and conditions are final, binding and
conclusive.

         The Compensation Committee is authorized to select eligible persons for
participation in the Amended Plan and, subject to the terms of the Amended Plan,
to determine the terms and conditions of each stock option granted under the
Amended Plan. Each stock option granted will be evidenced by a written agreement
between the Company and the optionee setting forth the terms and conditions of
such option.

         Shares Available. The maximum number of shares of Common Stock
available under the Amended Plan is 4,000,000 (as adjusted for the 2-for-1 stock
split on June 21, 2000) plus the number of shares available for the future grant
of stock options under the CDW 1996 Incentive Stock Option Plan and the total
number of shares of Common Stock available for the future grant of stock options
under the CDW Incentive Stock Option Plan and the CDW Director Stock Option Plan
combined, shall be available for grants of options under this Amended Plan,
reduced by the sum of the aggregate number of shares of Common Stock which
become subject to outstanding option plans. As of March 31, 2002, the total
number of shares available for the future grant of stock options under the
Amended Plan is 5,651,650, subject to adjustment in the event of a stock split,
stock dividend or other similar change in capitalization. If shares of Common
Stock subject to an option granted under the Amended Plan or any of the
aforementioned prior stock option plans are not issued by reason of the
expiration, termination, cancellation or forfeiture of that option, those shares
will be available for the grant of new options under the Amended Plan.

         Shares of Common Stock delivered upon the exercise of a stock option
granted under the Amended Plan may be treasury shares, authorized and unissued
shares, or a combination thereof. Stock options granted under the Amended Plan
may be either incentive stock options ("ISOs") or non-qualified stock options
("NQSOs"). An ISO is a stock option granted in accordance with Section 422 of
the Code that is intended by the Compensation Committee to constitute an ISO and
may entitle the optionee to favorable tax treatment as described below. An NQSO
is a stock option that is not an ISO.

         Eligibility to Participate. The Compensation Committee may grant
options under the Amended Plan to any officer, employee or consultant of the
Company or any subsidiary or affiliate of the Company or to any director,
including any non-employee director, of the Company, as it may, in its sole
discretion, from time to time select. As of the date of this Proxy Statement,
approximately 2,800 employees (which number includes officers) and nine
directors are eligible to participate in the Amended Plan. Except as described
below under "Non-Discretionary Grants of Stock Options to Non-Employee
Directors," no determination has yet been made as to the number of options, if
any, that any individual who is eligible to participate in the Amended Plan will
be granted.



                                      23




         Discretionary Options. The Compensation Committee will determine which
eligible persons will receive grants of stock options under the Amended Plan
and, subject to the limitations described below, will determine the number of
shares of Common Stock subject to each stock option grant, the related purchase
price per share of Common Stock, the period during which the stock option may be
exercised, whether the stock option will become exercisable in cumulative or
non-cumulative installments and in part or in full at any time and whether the
stock option is intended to constitute an ISO. The Compensation Committee may,
for any reason at any time, take action to cause any or all outstanding options
granted under the Amended Plan to become exercisable in part or in full. The
Compensation Committee may also establish performance measures or other criteria
that need to be satisfied as conditions to the grant of an option or to the
exercisability of all or a portion of an option. We will refer to options
granted automatically under the Amended Plan to non-employee directors as
"non-discretionary options" and all other options granted under the Amended Plan
as "discretionary options."

         Purchase Price. The purchase price per share of Common Stock subject to
a discretionary stock option granted under the Amended Plan may not be less than
100% of the Fair Market Value of a share of Common Stock on the date of grant.
If an ISO is granted to a person who, at the time of the grant, owns more than
10 percent of the Company's Common Stock, then the per share purchase price may
not be less than 110% of the Fair Market Value of a share of Common Stock on the
date of grant. The "Fair Market Value" of a share of Common Stock on a given
date is the closing transaction price of a share of Common Stock as reported on
The Nasdaq Stock Market on that date, or if there are no reported transactions
on such date, on the next preceding date for which a transaction was reported;
provided, however, that Fair Market Value may be determined by the Compensation
Committee by whatever means it, in the good faith exercise of its discretion,
shall deem appropriate.

         Limitations on Number of Shares Subject to Stock Options. To the extent
necessary for an option to be qualified performance-based compensation under
Section 162(m) of the Code and the rules and regulations thereunder, and
therefore to be fully deductible by the Company for federal income tax purposes
if the optionee's compensation in the year of exercise exceeds $1 million, the
maximum number of shares of Common Stock with respect to which stock options may
be granted under the Amended Plan during any fiscal year of the Company to any
person is 2,000,000 (as adjusted for the 2-for-1 stock split on June 21, 2000).

         Limitations on Period of Exercisability of ISOs. An ISO may not be
exercisable later than 10 years after its date of grant. If an ISO is granted to
a person who, at the time of the grant, owns more than 10 percent of the
Company's Common Stock, then that ISO may not be exercised later than five years
after its date of grant.

         Noncompetition. If an optionee is employed by, receives compensation
from or otherwise is associated with or agrees in principle to be employed by or
to receive compensation from or otherwise be associated as an officer, agent,
director, employee, shareholder, consultant or otherwise with a Competitor (as
defined in the Amended Plan) at any time prior to the expiration of the
optionee's options, (i) all of that optionee's unexercised options shall be
forfeited and (ii) the optionee shall be required to repay to the Company all
Option Proceeds. The Amended Plan defines Option Proceeds as (i) the difference
between (A) the Fair Market Value of a share of Common Stock on the date of
exercise and (B) the per share exercise price of the option, multiplied by (ii)
the number of shares of Common Stock acquired pursuant to any exercise of
options granted under the Amended Plan that occurs after the date 24 months
prior to the date of the optionee's termination of employment with the Company.

         Exercise of a Stock Option Following Termination of Employment or
Service. Unless otherwise provided in the agreement relating to a discretionary
stock option granted under the Amended Plan, the following rules apply in the
case of an optionee's termination of employment with, or service to, the
Company:

o  If an optionee's employment with, or service to, the Company terminates by
   reason of the disability of the optionee, each discretionary stock option
   granted under the Amended Plan to the optionee will become fully
   exercisable and may thereafter be exercised by such optionee (or such
   optionee's legal representative or similar person) until and including the
   earlier to occur of (i) the date that is one year after the date of the
   termination of employment or service or (ii) the expiration date of the
   term of such option.


                                      24




o  If an optionee retires on or after age 62 and has 10 or more years of
   continuous service at the time of retirement, each discretionary stock
   option granted under the Amended Plan to the optionee (i) will, to the
   extent not exercisable as of the effective date of the optionee's
   retirement, become exercisable in accordance with the vesting provisions
   set forth in the agreement relating to such option and (ii) upon becoming
   exercisable may be exercised by such optionee (or such optionee's legal
   representative or similar person) until the expiration date of the term of
   such option.

o  If an optionee's employment with, or service to, the Company is terminated
   because of the death of the optionee, each discretionary stock option
   granted under the Amended Plan to the optionee will become fully
   exercisable and may thereafter be exercised by such optionee's executor,
   administrator, legal representative, beneficiary or similar person until
   and including the earlier to occur of (i) the date that is one year after
   the date of death and (ii) the expiration date of the term of such option.

o  If an optionee's employment with, or service to, the Company terminates for
   any other reason, each discretionary stock option granted under the Amended
   Plan to the optionee will be exercisable only to the extent exercisable on
   the date of termination of employment or service and may thereafter be
   exercised by such optionee (or such optionee's legal representative or
   similar person) until and including the earlier to occur of (i) the date
   that is three months after the date of the termination of employment or
   service or (ii) the expiration date of the term of such option; provided,
   that if the optionee's employment with, or service to, the Company is
   terminated for Cause, all stock options granted under the Amended Plan and
   held by the optionee will terminate automatically on the effective date of
   the optionee's termination of employment or service. For purposes of the
   Amended Plan, "Cause" includes (i) the commission of a criminal act, fraud,
   gross negligence or willful misconduct against, or in derogation of the
   interests of the Company, (ii) divulging confidential information regarding
   the Company, (iii) interference with the relationship between the Company
   and any major supplier or customer, or (iv) the performance of any similar
   action that our Board of Directors or Compensation Committee, in its sole
   discretion, may deem to be sufficiently injurious to the interests of the
   Company to constitute cause for termination.

o  If an optionee dies during the period of exercisability following
   termination of employment or service described above, each discretionary
   stock option granted under the Amended Plan to the optionee will be
   exercisable only to the extent exercisable on the date of death and may
   thereafter be exercised by such optionee's executor, administrator, legal
   representative, beneficiary or similar person until and including the
   earlier to occur of (i) the date that is one year after the date of death
   or (ii) the expiration date of the term of such option.

         Notwithstanding the foregoing, with respect to discretionary stock
options granted to non-employee directors of the Company, the rules regarding
the exercise, cancellation or other disposition of such discretionary options
following termination of service as a non-employee director of the Company
will be determined by the Committee.

         Non-Discretionary Grants of Stock Options to Non-Employee Directors.
Under the terms of the Amended Plan, each non-employee director will be
granted options to purchase shares of Common Stock as follows:


                                      25




         Stock Option Grant upon Initial Election or Commencement of Service.
Each person who is first elected or first begins to serve as a Non-Employee
Director, other than by reason of termination of employment, on or after the
Annual Meeting will automatically be granted, on the date of such person's
initial election or commencement of service as a non-employee director, an
option to purchase 20,000 shares of Common Stock.

         Annual Stock Option Grant. On the date of each annual meeting of
shareholders, commencing with the Annual Meeting, each person who is a
non-employee director immediately prior to such meeting will be granted an
option to purchase 10,000 shares of Common Stock (which number will be
prorated if such non-employee director was first elected or began to serve as
a non-employee director after the date of the immediately proceeding annual
meeting of shareholders).

         Stock Option Grant in lieu of Annual Cash Retainer Fee. Each
non-employee director may elect to receive, in lieu of all or part of the
annual cash retainer fee that would otherwise be payable to such non-employee
director, on the date of each annual meeting of shareholders, commencing with
the Annual Meeting, options to purchase shares of Common Stock having a value
on the date of grant equal to the foregone amount of such retainer fee,
determined in accordance with the Black-Scholes valuation model.

         All of the above-described non-discretionary options are NQSOs, have a
per share purchase price equal to 100% of the Fair Market Value of a share of
Common Stock on the date of grant, are exercisable in one-fifth increments over
the five year period following the date of grant and expire 10 years after the
date of grant.

         Exercise of Non-Discretionary Stock Options Following Termination of
Service. The following rules apply to non-discretionary options granted to
non-employee directors under the Amended Plan in the case of a non-employee
director's termination of service to the Company:

o  If an optionee's service to the Company terminates by reason of the
   disability of the optionee, each non-discretionary stock option granted
   under the Amended Plan to the optionee will become fully exercisable and
   may thereafter be exercised by such optionee (or such optionee's legal
   representative or similar person) until and including the earlier to occur
   of (i) the date that is three years after the date of the termination of
   service or (ii) the expiration date of the term of such option.

o  If an optionee retires after 10 years or more of continuous service as a
   non-employee director of the Company, each non-discretionary stock option
   held by such optionee will, to the extent not exercisable as of the
   effective date of the optionee's retirement, become exercisable in
   accordance with the vesting provisions set forth in the agreement relating
   to such option and upon becoming exercisable may be exercised by such
   optionee (or such optionee's legal representative or similar person) until
   and including the earlier to occur of (i) the date that is five years after
   the effective date of the optionee's retirement of service or (ii) the
   expiration date of the term of such option.

o  If an optionee's service to the Company is terminated because of the death
   of the optionee, each non-discretionary stock option granted under the
   Amended Plan to the optionee will become fully exercisable and may
   thereafter be exercised by such optionee's executor, administrator, legal
   representative, beneficiary or similar person until and including the
   earlier to occur of (i) the date that is three years after the date of
   death and (ii) the expiration date of the term of such option.

o  If an optionee's service to the Company is terminated for any reason other
   than disability, retirement, death or for cause, each non-discretionary
   stock option granted under the Amended Plan to the optionee will be
   exercisable only to the extent such option is exercisable on the effective
   date of such optionee's ceasing to be a director and may thereafter be
   exercised by such optionee (or such optionee's legal representative or
   similar person) until and including the earlier to occur of (i) the date
   which is three years after the effective date of such optionee's ceasing to
   be a director and (ii) the expiration date of the term of such option;
   provided, that if the optionee's service to the Company is terminated for
   Cause, all stock options granted under the Amended Plan


                                      26




   and held by the optionee will terminate automatically on the effective date
   of the optionee's termination of service.

o  If an optionee dies during the period of exercisability following
   termination of service described above, each non-discretionary stock option
   granted under the Amended Plan to the optionee will be exercisable only to
   the extent exercisable on the date of death and may thereafter be exercised
   by such optionee's executor, administrator, legal representative,
   beneficiary or similar person until and including the earlier of (i) the
   expiration date of the term of such option and (ii) the date which is the
   later of (A) the date which is one year after the date of death and (B) the
   date which is three years after the effective date of such optionee's
   ceasing to be a director in the case of death after termination of service
   due to disability or for any other reason other than for Cause or
   retirement, or the date which is five years after the effective date of
   such optionee's ceasing to be a director in the case of death after
   termination of service due to retirement.

         Notwithstanding the foregoing, with respect to non-discretionary
stock options granted to non-employee directors under the CDW 2000 Incentive
Stock Option Plan prior to January 1, 2002, the rules regarding the exercise,
cancellation or other disposition of such non-discretionary options following
termination of service as a non-employee director of the Company will be
determined in accordance with the terms of the CDW 2000 Incentive Stock Option
Plan, as in effect prior to such date.

         Change in Control. Upon a Change in Control (as defined in the Amended
Plan) in which the Company's shareholders receive shares of common stock that
are publicly traded, all outstanding options granted under the Amended Plan will
immediately become fully exercisable and there will be substituted for each
share of Common Stock available under the Amended Plan, whether or not then
subject to an outstanding option, the number and class of shares into which each
outstanding share of Common Stock shall be converted pursuant to the Change in
Control. In the event of any such substitution, the purchase price per share of
each option will be appropriately adjusted by the Compensation Committee,
without an increase in the aggregate purchase price.

         Upon a Change in Control in which the Company's shareholders receive
consideration other than shares of common stock that are publicly traded, each
outstanding option granted under the Amended Plan will be surrendered to the
Company by the holder thereof, and each such option will immediately be
cancelled by the Company, and the holder will receive, within 10 days of the
occurrence of a Change in Control, a cash payment from the Company in an amount
equal to the number of shares of Common Stock then subject to the option,
multiplied by the excess, if any, of (i) the greater of (A) the highest per
share price offered to shareholders of the Company in any transaction whereby
the Change in Control takes place or (B) the Fair Market Value of a share of
Common Stock on the date of occurrence of the Change in Control over (ii) the
purchase price per share of Common Stock subject to the option.

         Exercise of Stock Options; Non-Transferability; Designation of
Beneficiaries. Payment for shares of Common Stock purchased upon the exercise of
an option granted pursuant to the Amended Plan will be made as set forth in the
agreement relating to such option. Such agreement may provide for payment (i) in
cash, (ii) by delivery of certain previously-acquired shares of Common Stock,
(iii) by delivery of an irrevocable notice of exercise to a broker-dealer
acceptable to the Company or (iv) by a combination of cash and delivery of
certain previously-acquired shares of Common Stock. Except as otherwise set
forth in the agreement relating to an option, no stock option granted under the
Amended Plan may be transferred other than by will or the laws of descent and
distribution or pursuant to beneficiary designation procedures approved by the
Company. Except to the extent permitted by the foregoing sentence, each stock
option may be exercised during an optionee's lifetime only by the optionee or
the optionee's legal representative or similar person. Each optionee may file
with the Compensation Committee a written designation of one or more persons as
such optionee's beneficiary or beneficiaries (both primary and contingent) in
the event of such optionee's death.


                                      27




Federal Income Tax Consequences

         The following is a brief overview of the United States federal income
tax consequences of participation in the Amended Plan and should not be relied
upon as being a complete description. It does not address the state or local tax
aspects of participation in the Amended Plan.

         Grant of Option. An optionee will not recognize taxable income upon the
grant of a stock option under the Amended Plan.

         Exercise of Non-Qualified Options. An optionee will recognize
compensation taxable as ordinary income, and the Company generally will be
allowed a corresponding deduction for federal income tax purposes, in an amount
equal to the excess of the fair market value, on the date of exercise of an
NQSO, of the shares of Common Stock acquired over the purchase price paid for
the shares.

         Exercise of Incentive Stock Options. An optionee will not recognize any
taxable income by reason of exercise of an ISO, and the Company will not be
allowed any deduction with respect to the exercise at that time. However, the
excess, if any, of the fair market value, at the time of exercise, of the Common
Stock acquired upon the exercise over the purchase price for the shares will be
included in alternative minimum taxable income and may be subject to the
alternative minimum tax.

         Qualifying Disposition of ISO Shares. If an optionee disposes of Common
Stock acquired pursuant to the exercise of an ISO two years or more after the
date of grant of the ISO and one year or more after the date of transfer of
Common Stock to the optionee, the amount, if any, realized in excess of the
purchase price for such Common Stock will be treated as long-term capital gain
or the amount, if any, by which the purchase price exceeds the amount realized
upon the disposition will be treated as a long-term capital loss. The Company
will not be entitled to any deduction with respect to a disposition of Common
Stock occurring under the circumstances described in this paragraph.

         Disqualifying Disposition of ISO Shares. If an optionee disposes of
Common Stock acquired pursuant to the exercise of an ISO within the period
ending on the later of two years after the date of grant of the ISO and one year
after the date of transfer of Common Stock to the optionee, the optionee will
recognize ordinary income, and the Company will be entitled to a corresponding
deduction, in an amount equal to the amount, if any, realized in excess of the
purchase price for the Common Stock, but only considering the amount realized to
the extent it does not exceed the fair market value of the Common Stock on the
date of exercise. Any amount realized upon disposition in excess of the fair
market value of the Common Stock on the date of exercise will be treated as
long-term capital gain if the Common Stock has been held for more than 12 months
or as a short-term capital gain if the Common Stock has been held for a shorter
period. If the amount realized upon disposition is less than the purchase price
for the shares, the excess of the purchase price over the amount realized will
be treated as a long-term or short-term capital loss, depending on the holding
period of the Common Stock. The Company will not be entitled to any deduction
with respect to the amount recognized by the employee as capital gain.

         Income Tax Withholding. The taxable compensation recognized by the
optionee upon the exercise of an NQSO will be subject to withholding of tax by
the Company.

Benefits Table

         The following table sets forth the number of shares of Common Stock
underlying options which automatically would be granted under the Amended Plan
to current non-employee directors on the date of each annual meeting of
shareholders beginning with the Annual Meeting if the Amended Plan is approved
by shareholders. However, the additional options that each non-employee director
may elect to receive on the date of each annual meeting of shareholders in lieu
of his or her annual cash retainer fee are not included in the table, because
the number of shares subject to such additional options is determined in
accordance with the Black-Scholes valuation model and depends upon the amount of
the cash retainer fee that each non-employee director elects to


                                      28




forego and the trading price of the Common Stock on the date of grant and
therefore is not determinable until the date of grant.

         No determination has been made by the Compensation Committee regarding
future discretionary stock option grants under the Amended Plan to directors,
officers and other employees.

(1) The exercise price per share of options automatically granted to
non-employee directors would be 100% of the fair market value of a share of
Common Stock on the date of grant of the option. On April 5, 2002, the closing
transaction price per share of Common Stock as reported on The Nasdaq Stock
Market was $49.58. The general terms of each option is described above under
"Description of the Amended Plan - Non-Discretionary Grants of Stock Options
to Non-Employee Directors."

Effective Date, Amendment and Termination

         If approved by shareholders at the Annual Meeting, the Amended Plan
will become effective as of January 1, 2002. The Board may amend the Amended
Plan at any time, subject to any requirement of shareholder approval required by
applicable law, rule or regulation, including Sections 162(m) and 422 of the
Code. Nonetheless, the Board may not increase the number of shares available
under the Amended Plan, effect any change inconsistent with Section 422 of the
Code, extend the term of the Amended Plan or permit the grant of a stock option
having an exercise price less than 100% of Fair Market Value on the date of
grant of such option, without shareholder approval. No amendment may impair the
rights of a holder of an outstanding stock option granted under the Amended Plan
without the holder's consent.

         The Amended Plan will terminate on March 16, 2010, but may be
terminated earlier by the Company's Board of Directors. Termination of the
Amended Plan will not affect the terms or conditions of any stock option granted
under the Amended Plan prior to the termination date. No stock options may be
granted under the Amended Plan after it has been terminated.

         The approval of the Amended Plan requires the affirmative vote of the
holders of a majority of the shares of Common Stock represented at the Annual
Meeting, in person or by proxy, and entitled to vote thereon.

    The Board of Directors recommends a vote FOR approval of the Amended Plan.

                             PROPOSAL TO APPROVE THE
                             -----------------------
                        CDW EMPLOYEE STOCK PURCHASE PLAN
                        --------------------------------

General

         The Board of Directors is proposing for shareholder approval the CDW
Computer Centers, Inc. Employee Stock Purchase Plan (the "ESPP"). The ESPP was
adopted by the Board of Directors on April 2, 2002, to become effective July 1,
2002, subject to shareholder approval within 12 months after its adoption by the
Board of Directors.

         The purposes of the ESPP are to encourage and facilitate the purchase
of shares of Common Stock by eligible employees of the Company and its
subsidiaries and to provide an additional incentive to promote the best
interests of the Company and its subsidiaries and an additional opportunity to
participate in their economic success.

Description of the ESPP

         The following is a description of the ESPP. This description is
qualified in its entirety by reference to the plan document, a copy of which is
attached to this Proxy Statement as Exhibit B and incorporated herein by
reference.

         Administration. The ESPP will be administered by the Compensation
Committee. The Compensation Committee will have discretionary authority to
interpret the ESPP and to establish rules and regulations relating to the ESPP
from time to time and to make all other determinations necessary or advisable
for the administration of the ESPP.

         Shares Available. The maximum number of shares available for purchase
under the ESPP will be 500,000, subject to adjustment in the event of certain
changes to the Company's capital structure as described in the ESPP. The shares
of Common Stock sold under the ESPP may be treasury shares, authorized and
unissued shares, shares purchased in the open market or any combination of the
foregoing.

         Eligibility. Any employee of the Company or any of its subsidiaries is
eligible to participate in the ESPP as of the first day of any purchase period
(as defined below), provided that such employee has at least 90 days of
continuous service with the Company or a subsidiary immediately prior to such
date. Notwithstanding anything to the contrary contained in the ESPP, no
employee may be granted an option under the ESPP to purchase shares of Common
Stock if such employee, immediately after the grant of such option, would own 5%
or more of the total combined voting power or value of all classes of stock of
the Company or an affiliate. As of the date of this Proxy Statement,
approximately 2,800 employees (which number includes officers) are eligible to
participate in the ESPP.

         Participation and Payroll Deductions. Eligible employees may purchase
shares of Common Stock at below-market prices through payroll deductions during
each purchase period, with amounts accumulated during each purchase period. To
participate in the ESPP, an eligible employee must make a request to the
Compensation Committee or its designated agent, at the time and in the manner
specified by the Compensation Committee, stating the amount of the requested
payroll deduction. The amount of the payroll deduction must be a whole
percentage amount or, if permitted by the Compensation Committee, a whole dollar
amount that does not exceed 15%, or a lesser percentage determined by the
Compensation Committee, of the employee's compensation (before withholding or
other deductions) paid during the purchase period by the Company or any of its
subsidiaries. The amounts deducted from participants' pay is reflected in an
account maintained on the books and records of the Company. No interest is paid
on the amounts credited to these accounts.


                                      30




         Deduction Changes and Withdrawal. Employees may change their rate of
payroll deduction at any time. This change becomes effective as of the beginning
of the next purchase period following receipt of a new election form. A
participant may suspend his or her payroll deductions under the ESPP by giving
notice at the time and in the manner prescribed by the Compensation Committee.
At the election of the participant, upon suspending his or her payroll
deductions, such participant may either receive in cash the entire balance that
has accumulated in his or her account through the date of such suspension of
participation or have such account balance applied to the purchase of shares of
Common Stock at the close of the purchase period. A participant who withdraws
from the ESPP may again participate at the start of any subsequent purchase
period by filing a new request to participate with the Compensation Committee or
its designated agent at the time and in the manner specified by the Compensation
Committee.

         Purchase of Shares. Shares of Common Stock will be offered under the
ESPP through a series of successive purchase periods, each with a duration of
three calendar months. Purchases will occur under the ESPP on the last day of
each purchase period. Funds held in a participant's account on the last day of
the purchase period will be used to purchase shares of Common Stock for the
participant. Shares will be purchased at 85% of fair market value on the last
day of the purchase period, or at 85% of fair market value as of the first day
of the purchase period, whichever price is lower. The fair market value of a
share of Common Stock on any relevant date under the ESPP will be the closing
transaction price of a share of Common Stock as reported on The NASDAQ Stock
Market on the date as of which such value is being determined or, if there shall
be no reported transactions on such date, on the next preceding date for which a
transaction was reported. On April 5, 2002, the fair market value per share of
Common Stock was $49.58.

         Purchases are subject to the aggregate limitation on the number of
shares that are available under the ESPP and the ESPP limitations applicable
to individual participants. The provisions of the ESPP do not impose
restrictions upon the resale by holders of Common Stock acquired under the
ESPP. Certain resale restrictions are imposed, however, by the terms of the
Company's insider trading and confidentiality policies and the provisions of
the federal securities laws. In addition, the Compensation Committee has the
discretion to require that shares be deposited directly with a broker
designated by the Compensation Committee and that the shares be retained with
such broker for a designated period of time.

         A participant's rights under the ESPP are not transferable by the
participant during his or her lifetime.

         Limitations on Purchases of Shares. Notwithstanding anything to the
contrary in the ESPP, no participant may be granted an option to purchase
shares of Common Stock that permits such participant to purchase in any
calendar year under the ESPP and all other employee stock purchase plans
(within the meaning of Section 423 of the Code) of the Company and its
subsidiaries shares of Common Stock with an aggregate fair market value
(determined at the time such option is granted) in excess of $25,000. Further
notwithstanding anything contained in the ESPP to the contrary, no participant
may purchase more than 325 shares of Common Stock during any purchase period.

         Termination of Participation. When a participant dies, terminates
employment or otherwise ceases to be an eligible employee under the ESPP, the
participant's participation in the ESPP will terminate immediately. Upon such
terminating event, the cash credited to the participant's account on the date
of termination, certificates for the number of full shares of Common Stock
held for his or her benefit, and the cash equivalent for any fractional share
so held, will be delivered to the participant or his or her legal
representative, as the case may be, as soon as practicable after such
terminating event.

         Change in Control. In the event of a change in control of the Company
(as defined in the ESPP), the then current purchase period shall cease, and
the Compensation Committee, in its sole discretion, will either direct that
the cash credited to all participants' accounts be applied to purchase shares
of Common Stock or that such cash be returned to participants, and the ESPP
will terminate immediately thereafter.


                                      31




         Amendment and Termination of the ESPP. The Compensation Committee may
amend the ESPP at any time and for any reason; provided, however, that no
amendment may (i) materially adversely effect any purchase rights outstanding
under the ESPP with respect to the purchase period in which such amendment is
to be effected, (ii) increase the maximum number of shares of Common Stock
that may be purchased under the ESPP, (iii) decrease the purchase price for
any purchase period below 85% of the fair market value on the first day of
such purchase period or the last day of such purchase period, whichever is
less, or (iv) adversely affect the qualification of the ESPP under Section 423
of the Internal Revenue Code.

         The Board of Directors may terminate the ESPP at any time. Upon
termination of the ESPP, one or more certificates for the number of full
shares of Common Stock held for each participant's benefit and the cash
equivalent of any fractional share so held will be delivered to such
participant as soon as practicable after the ESPP terminates, and, except as
otherwise provided in the event of a change in control, the cash, if any,
credited to the such participant's account, will also be distributed to such
participant as soon as practicable after the ESPP terminates.

Federal Income Tax Consequences

         The following is a brief summary of the United States federal income
tax consequences under the ESPP.

         The ESPP is intended to be an "employee stock purchase plan" within
the meaning of Section 423 of the Code. Under Section 423, an eligible
employee who elects to participate in the ESPP will not realize any taxable
income at the time stock is purchased under the ESPP for the employee.

         If a participant does not dispose of the stock purchased under the
ESPP within two years after the first day of the purchase period in which the
stock was purchased, then upon the disposition of the stock, the participant
will recognize compensation taxable as ordinary income in an amount equal to
the lesser of (a) the excess of the fair market value of the stock at the time
of disposition over the purchase price under the ESPP and (b) 15% of the fair
market value of the stock on the first day of the purchase period. The
participant's cost basis in the stock will be increased by the amount of
ordinary income recognized by the participant. The portion of the gain that is
in excess of the amount recognized as ordinary income, if any, is taxed as
long-term capital gain. If the stock is disposed of at a price below the
purchase price under the ESPP, the loss will be treated as long-term capital
loss. The Company will not be entitled to any deduction with respect to a
disposition of the stock occurring under these circumstances.

         If a participant disposes of the stock purchased under the ESPP
within two years after the first day of the purchase period in which the stock
was purchased, then upon the disposition of the stock, the participant will
recognize compensation taxable as ordinary income, and the Company will be
entitled to a corresponding deduction, in an amount equal to the excess of the
fair market value of the stock on the last day of the purchase period in which
the stock was purchased over the purchase price of the stock under the ESPP.
The participant's cost basis in the stock will be increased by the amount of
ordinary income recognized by such participant. In addition, upon the
disposition of the stock, a participant will recognize capital gain or loss
equal to the difference between the price at which the stock is disposed of
and the cost basis for the stock, as so increased. The Company will not be
entitled to any deduction with respect to the amount recognized by such
participant as capital gain.

New Plan Benefits

         The benefits that might be received by employees under the ESPP
cannot be determined because the benefits depend upon the degree of
participation by employees and the trading price of the Common Stock in future
purchase periods.

         The approval of the ESPP requires the affirmative vote of the holders
of a majority of the shares of Common Stock represented at the Annual Meeting,
in person or by proxy, and entitled to vote thereon.

      The Board of Directors recommends a vote FOR approval of the ESPP.

                                    Exhibit A

                      CDW 2000 INCENTIVE STOCK OPTION PLAN
                      ------------------------------------
                       (As Amended through April 2, 2002)
I.  INTRODUCTION

1.1    Purposes.   The purposes of the 2000 Incentive Stock Option Plan (the
"Plan") of CDW Computer Centers, Inc., an Illinois corporation (the
"Company"), are (i) to align the interests of the Company's stockholders and
the recipients of options under this Plan by increasing the proprietary
interest of such recipients in the Company's growth and success, (ii) to
advance the interests of the Company by attracting, motivating and retaining
directors, officers, other employees, consultants and well-qualified persons
who are not officers or employees of the Company ("Non-Employee Directors")
for service as directors of the Company and (iii) to motivate such persons to
act in the long-term best interests of the Company and its stockholders.

1.2    Administration.   This Plan shall be administered by a committee (the
"Committee") designated by the Board of Directors of the Company (the "Board")
consisting of two or more members of the Board. Each member of the Committee
may be a "Non-Employee Director" within the meaning of Rule 16b-3 under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), and an
"outside director" within the meaning of Section 162(m) of the Internal
Revenue Code of 1986, as amended (the "Code").

         The Committee shall, subject to the terms of this Plan, select eligible
persons for participation in this Plan and shall determine the number of shares
of Common Stock subject to each option granted hereunder, the exercise price of
such option, the time and conditions of exercise of such option and all other
terms and conditions of such option, including, without limitation, the form of
the option agreement. The Committee may, in its sole discretion and for any
reason at any time, subject to the requirements of Section 162(m) of the Code
and regulations thereunder in the case of an option intended to be qualified
performance-based compensation, take action such that any or all outstanding
options shall become exercisable in part or in full. The Committee shall,
subject to the terms of this Plan, interpret this Plan and the application
thereof, establish rules and regulations it deems necessary or desirable for the
administration of this Plan and may impose, incidental to the grant of an
option, conditions with respect to the grant, such as limiting competitive
employment or other activities. All such interpretations, rules, regulations and
conditions shall be final, binding and conclusive. Each option shall be
evidenced by a written agreement (an "Agreement") between the Company and the
optionee setting forth the terms and conditions of such option.

         To the extent permitted by applicable law, the Committee may delegate
some or all of its power and authority hereunder to the Board or the Chairman of
the Board and Chief Executive Officer or other executive officer of the Company
as the Committee deems appropriate; provided, however, that (i) the Committee
may not delegate its power and authority to the Board or the Chairman of the
Board and Chief Executive Officer or other executive officer of the Company with
regard to the grant of an award to any person who is a "covered employee" within
the meaning of Section 162(m) of the Code or who, in the Committee's judgment,
is likely to be a covered employee at any time during the period an award
hereunder to such employee would be outstanding and (ii) the Committee may not
delegate its power and authority to the Chairman of the Board and Chief
Executive Officer or other executive officer of the Company with regard to the
selection for participation in this Plan of an officer or other person subject
to Section 16 of the Exchange Act or decisions concerning the timing, pricing or
amount of an award to such an officer or other person.

         No member of the Board or Committee, and neither the Chairman of the
Board and Chief Executive Officer nor other executive officer to whom the
Committee delegates any of its power and authority hereunder, shall be liable
for any act, omission, interpretation, construction or determination made in
connection with this Plan in good faith, and the members of the Board and the
Committee and the Chairman of the Board and Chief Executive Officer or other
executive officer shall be entitled to indemnification and reimbursement by
the Company in respect of any claim, loss, damage or expense (including
attorneys' fees) arising therefrom to the full extent permitted by law,


                                      34




except as otherwise may be provided in the Company's Articles of Incorporation
and/or By-Laws, and under any directors' and officers' liability insurance
that may be in effect from time to time.

         A majority of the Committee shall constitute a quorum. The acts of
the Committee shall be either (i) acts of a majority of the members of the
Committee present at any meeting at which a quorum is present or (ii) acts
approved in writing by all of the members of the Committee without a meeting.

1.3    Eligibility.    Participants in this Plan shall consist of such directors
(including Non-Employee Directors), officers and other employees, persons
expected to become directors, officers and other employees and consultants of
the Company, its affiliates and its subsidiaries from time to time
(individually a "Subsidiary" and collectively the "Subsidiaries") as the
Committee in its sole discretion may select from time to time. For purposes of
this Plan, references to employment shall also mean an agency relationship
with the Company and references to employment by the Company shall also mean
employment by an affiliate of the Company or a Subsidiary. The Committee's
selection of a person to participate in this Plan at any time shall not
require the Committee to select such person to participate in this Plan at any
other time. Non-Employee Directors of the Company shall be eligible to
participate in this Plan in accordance with Section III.


1.4    Shares Available.    Subject to adjustment as provided in Section 4.7,
4,000,000 shares of the common stock, par value $0.01 per share, of the Company
("Common Stock") plus the sum of: (i) the number of shares of Common Stock
available for the future grant of stock options under the CDW 1996 Incentive
Stock Option Plan and (ii) the total number of shares of Common Stock available
for the future grant of stock options under the CDW Incentive Stock Option Plan
and the CDW Director Stock Option Plan combined, shall be available for grants
of options under this Plan, reduced by the sum of the aggregate number of shares
of Common Stock which become subject to outstanding options. To the extent that
shares of Common Stock subject to an outstanding option are not issued or
delivered by reason of the expiration, termination, cancellation or forfeiture
of such option (other than by reason of the delivery or withholding of shares of
Common Stock to pay all or a portion of the exercise price of such option, or to
satisfy all or a portion of the tax withholding obligations relating to such
option), then such shares of Common Stock shall again be available under this
Plan.

         Shares of Common Stock shall be made available from authorized and
unissued shares of Common Stock, or authorized and issued shares of Common Stock
reacquired and held as treasury shares or otherwise or a combination thereof.

         To the extent necessary for an award to be qualified performance-based
compensation under Section 162(m) of the Code and the regulations thereunder,
the maximum number of shares of Common Stock with respect to which options may
be granted during any calendar year to any person shall be 2,000,000, subject to
adjustment as provided in Section 4.7.

II.  STOCK OPTIONS

2.1    Grants of Stock Options.    The Committee may, in its discretion, grant
options to purchase shares of Common Stock to such eligible persons as may be
selected by the Committee. Each option, or portion thereof, that is not an
Incentive Stock Option, shall be a "Non-Statutory Stock Option". An Incentive
Stock Option may not be granted to any person who is not an employee of the
Company or any subsidiary (as defined in Section 424 of the Code). An
"Incentive Stock Option" shall mean an option to purchase shares of Common
Stock that meets the requirements of Section 422 of the Code, or any successor
provision, which is intended by the Committee to constitute an Incentive Stock
Option. Each Incentive Stock Option shall be granted within ten years of the
date this Plan is adopted by the Board. To the extent that the aggregate Fair
Market Value (determined as of the date of grant) of shares of Common Stock
with respect to which options designated as Incentive Stock Options are
exercisable for the first time by a participant during any calendar year
(under this Plan or any other plan of the Company, or any parent or subsidiary
as defined in Section 424 of the Code) exceeds the amount (currently $100,000)
established by the Code, such options shall constitute Non-Statutory Stock
Options. "Fair Market Value" shall mean the closing transaction price of a
share of


                                      35




Common Stock as reported on The NASDAQ Stock Market on the date as of which
such value is being determined or, if there shall be no reported transactions
on such date, on the next preceding date for which a transaction was reported;
provided, however, that Fair Market Value may be determined by the Committee
by whatever means or method as the Committee, in the good faith exercise of
its discretion, shall at such time deem appropriate.

2.2    Terms of Stock Options.   Options shall be subject to the following terms
and conditions and shall contain such additional terms and conditions, not
inconsistent with the terms of this Plan, as the Committee shall deem
advisable:

         (a) Number of Shares and Purchase Price. The number of shares of
Common Stock subject to an option and the purchase price per share of Common
Stock purchasable upon exercise of the option shall be determined by the
Committee; provided, however, that the purchase price per share of Common
Stock purchasable upon exercise of an option shall not be less than 100% of
the Fair Market Value of a share of Common Stock on the date of grant of such
option; provided further, that if an Incentive Stock Option shall be granted
to any person who, at the time such option is granted, owns capital stock
possessing more than ten percent of the total combined voting power of all
classes of capital stock of the Company (or of any parent or subsidiary as
defined in Section 424 of the Code) (a "Ten Percent Holder"), the purchase
price per share of Common Stock shall be the price (currently 110% of Fair
Market Value) required by the Code in order to constitute an Incentive Stock
Option.

         (b) Option Period and Exercisability. The period during which an
option may be exercised shall be determined by the Committee; provided,
however, that no Incentive Stock Option shall be exercised later than ten
years after its date of grant and provided further, that if an Incentive Stock
Option shall be granted to a Ten Percent Holder, such option shall not be
exercised later than five years after its date of grant. The Committee may, in
its discretion, establish performance measures or other criteria which shall
be satisfied or met as a condition to the grant of an option or to the
exercisability of all or a portion of an option. The Committee shall determine
whether an option shall become exercisable in cumulative or non-cumulative
installments and in part or in full at any time. An exercisable option, or
portion thereof, may be exercised only with respect to whole shares of Common
Stock.

         (c) Method of Exercise. An option may be exercised (i) by giving
written notice to the Company specifying the number of whole shares of Common
Stock to be purchased and accompanied by payment therefor in full (or
arrangement made for such payment to the Company's satisfaction) either (A) in
cash, (B) by delivery (either actual delivery or by attestation procedures
established by the Company) of previously owned whole shares of Common Stock
(which the optionee has held for at least six months prior to the delivery of
such shares or which the optionee purchased on the open market and in each
case for which the optionee has good title, free and clear of all liens and
encumbrances) having an aggregate Fair Market Value, determined as of the date
of exercise, equal to the aggregate purchase price payable by reason of such
exercise, (C) in cash by a broker-dealer acceptable to the Company to whom the
optionee has submitted an irrevocable notice of exercise or (D) a combination
of (A) and (B), in each case to the extent set forth in the Agreement relating
to the option and (ii) by executing such documents as the Company may
reasonably request. Any fraction of a share of Common Stock which would be
required to pay such purchase price shall be disregarded and the remaining
amount due shall be paid in cash by the optionee. No certificate representing
Common Stock shall be delivered until the full purchase price therefor has
been paid (or arrangement made for such payment to the Company's
satisfaction).

         (d) Non-Competition. In the event that an optionee is employed by,
receives compensation from or otherwise is associated with or has agreed in
principle to be employed by or to receive compensation from or otherwise be
associated as an officer, agent, director, employee, shareholder, consultant
or otherwise with a Competitor (as hereinafter defined) of the Company at any
time prior to the expiration of the optionee's options: (i) any and all
unexercised options shall be forfeited and (ii) any and all Option Proceeds
(as hereinafter defined) shall be immediately due and payable by the optionee
to the Company. For purposes of this Section, "Competitor" shall mean any
entity or person which engages for any portion of its business in the sale of
personal computer products to residents of the United States. For purposes of
this Section, "Option Proceeds" shall mean (i) the difference between (A) the
Fair Market Value of a share of Common Stock on the date of exercise and (B)
the per share exercise price


                                      36




of the option, multiplied by (ii) the number of shares of Common Stock
acquired pursuant to any exercise of options issued under this Plan which
occurs after the date 24 months prior to the date of the optionee's
termination of employment with the Company. 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 optionee in respect of a breach by the
optionee of any duty or obligation to the Company.

2.3      Termination of Employment or Service

         (a) Disability. Subject to paragraph (e) below and unless otherwise
specified in the Agreement relating to an option, if an optionee's employment
with or service to the Company terminates by reason of Disability, each option
held by such optionee shall be fully exercisable and may thereafter be
exercised by such optionee (or such optionee's legal representative or similar
person) until and including the earlier to occur of (i) the date which is one
year after the effective date of such optionee's termination of employment or
service and (ii) the expiration date of the term of such option. For purposes
of this Plan, "Disability" shall mean the inability of an optionee
substantially to perform such optionee's duties and responsibilities for a
continuous period of at least six months.

         (b) Retirement. Subject to paragraph (e) below and unless otherwise
specified in the Agreement relating to an option, if an optionee's employment
with or service to the Company terminates by reason of retirement on or after
age 62 after a minimum of 10 years of continuous employment with or service to
the Company ("Retirement"), each option held by such optionee (i) shall, to
the extent not exercisable as of the effective date of the optionee's
retirement, become exercisable in accordance with the vesting provisions set
forth in the Agreement relating to such option and (ii) upon becoming
exercisable may be exercised by such optionee (or such optionee's legal
representative or similar person) until the expiration date of the term of
such option.

         (c) Death. If an optionee's employment with or service to the Company
terminates by reason of death, each option held by such optionee shall be
fully exercisable and may thereafter be exercised by such optionee's executor,
administrator, legal representative, beneficiary or similar person until and
including the earlier to occur of (i) the date which is one year after the
date of death and (ii) the expiration date of the term of such option.

         (d) Other Termination. Subject to paragraph (e) below and unless
otherwise specified in the Agreement relating to an option, if an optionee's
employment with or service to the Company terminates for any reason other than
Disability, Retirement or death or for Cause, each option held by such
optionee shall be exercisable only to the extent that such option is
exercisable on the effective date of such optionee's termination of employment
or service and may thereafter be exercised by such optionee (or such
optionee's legal representative or similar person) until and including the
earlier to occur of (i) the date which is three months after the effective
date of such optionee's termination of employment or service and (ii) the
expiration date of the term of such option. For purposes of this Plan, "Cause"
shall mean (i) the commission of a criminal act, fraud, gross negligence or
willful misconduct against, or in derogation of, the interests of the Company;
(2) divulging confidential information regarding the Company; (3) interference
with the relationship between the Company and any major supplier or customer;
or (4) the performance of any similar action that the Committee, in its sole
discretion, may be deem to be sufficiently injurious to the interests of the
Company to constitute cause for termination.

         (e) Termination of Employment - Incentive Stock Options. Unless
otherwise specified in the Agreement relating to an option, if the employment
with the Company of a holder of an Incentive Stock Option terminates by reason
of Permanent and Total Disability (as defined in Section 22(e)(3) of the
Code), each Incentive Stock Option held by such optionee shall be exercisable
to the extent set forth in Section 2.3(a), and may thereafter be exercised by
such optionee (or such optionee's legal representative or similar person)
until and including the earlier to occur of (i) the date which is one year
after the effective date of such optionee's termination of employment and (ii)
the expiration date of the term of such option.

         Unless otherwise specified in the Agreement relating to an option, if
the employment with the Company of a holder of an Incentive Stock Option
terminates for any reason other than Permanent and Total Disability or death
or


                                      37




for Cause, each Incentive Stock Option held by such optionee shall be
exercisable to the extent set forth in Section 2.3(a), Section 2.3(b) or
Section 2.3(d), as applicable, and may thereafter be exercised by such holder
(or such holder's legal representative or similar person) until and including
the earlier to occur of (i) the date which is three months after the effective
date of such optionee's termination of employment and (ii) the expiration date
of the term of such option.

         (f) Death Following Termination of Employment or Service. Unless
otherwise specified in the Agreement relating to an option, if an optionee
dies during the period set forth in Section 2.3(a), Section 2.3(b), Section
2.3(d), if any, or Section 2.3(e) , each option held by such optionee shall be
exercisable only to the extent that such option is exercisable on the date of
such optionee's death and may thereafter be exercised by such optionee's
executor, administrator, legal representative, beneficiary or similar person
until and including the earlier to occur of (i) the date which is one year
after the date of death and (ii) the expiration date of the term of such
option.

         (g) Cause. Notwithstanding anything to the contrary in this Plan or
in any Agreement relating to an option, if the employment with or service to
the Company of the holder of an option is terminated by the Company for Cause,
each option held by such holder shall terminate automatically on the effective
date of such holder's termination of employment or service.


III.  PROVISIONS RELATING TO NON-EMPLOYEE DIRECTORS

3.1      Eligibility.   Each Non-Employee Director shall be granted options to
purchase shares of Common Stock in accordance with this Section III. All
options granted under this Section III shall constitute Non-Statutory Stock
Options.

3.2      Automatic Grants of Stock Options.   Each Non-Employee Director shall
be granted Non-Statutory Stock Options as follows:

         (a) Time of Grants; Number of Shares. Automatic grants of
Non-Statutory Stock Options shall be made on the dates and with respect to the

the annual meeting of stockholders to be held in 2002, during the period that
such election is in effect, options having the terms (other than the number of

conditions, not inconsistent with the terms of this Plan, as the Committee
shall deem advisable:

         (a) Number of Shares and Purchase Price. The number of shares of

per share of Common Stock purchasable upon exercise of the option shall be
determined by the Committee; provided, however, that the purchase price per
share of Common Stock purchasable upon exercise of the option shall not be
less than 100% of the Fair Market Value of a share of Common Stock on the date
of grant of such option.

         (b) Exercise Period and Exercisability. The period during which a
Discretionary Director Option may be exercised shall be determined by the
Committee. The Committee may, in its discretion, establish performance
measures which shall be satisfied or met as a condition to the grant of a

IV.  GENERAL

4.1    Effective Date and Term of Plan.   This Plan, as amended through April 2,
2002, shall be submitted to the stockholders of the Company for approval and,
if approved by the affirmative vote of a majority of the shares of Common
Stock present in person or represented by proxy at the 2002 annual meeting of
stockholders, shall become effective as of January 1, 2002. No option may be
exercised prior to the date of such stockholder approval. This Plan shall
terminate on March 16, 2010, unless terminated earlier by the Board.
Termination of this Plan shall not affect the terms or conditions of any
option granted prior to termination.

4.2    Amendments.   The Board may amend this Plan as it shall deem advisable,
subject to any requirement of stockholder approval required by applicable law,
rule or regulation, including Section 162(m) and Section 422 of the Code;
provided, however, that no amendment shall be made without stockholder
approval if such amendment would (a) increase the maximum number of shares of
Common Stock available under this Plan (subject to Section 4.7), (b) effect
any change inconsistent with Section 422 of the Code, (c) extend the term of
this Plan or (d) permit the


                                      40




granting of a stock option having a purchase price per share of Common Stock
of less than 100% of the Fair Market Value of a share of Common Stock on the
date of grant of such stock option. No amendment may impair the rights of a
holder of an outstanding option without the consent of such holder.

4.3    Agreement. No option shall be valid until an Agreement is executed by the
Company and the optionee and, upon execution by the Company and the optionee
and delivery of the Agreement to the Company, such option shall be effective
as of the effective date set forth in the Agreement.

4.4    Non-Transferability. Unless otherwise specified in the Agreement relating
to an option, no option hereunder shall be transferable other than by will or
the laws of descent and distribution or pursuant to beneficiary designation
procedures approved by the Company. Except to the extent permitted by the
foregoing sentence, each option may be exercised during the optionee's
lifetime only by the optionee or the optionee's legal representative or
similar person. Except as permitted by the second preceding sentence, no
option hereunder shall 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 any option hereunder, such option and all rights thereunder shall
immediately become null and void.

4.5    Tax Withholding.   The Company shall have the right to require, prior to
the issuance or delivery of any shares of Common Stock, payment by the optionee
of any Federal, state, local or other taxes which may be required to be withheld
or paid in connection with an option hereunder. An Agreement may provide that
(i) the Company shall withhold whole shares of Common Stock which would
otherwise be delivered upon exercise of the option having an aggregate Fair
Market Value determined as of the date the obligation to withhold or pay taxes
arises in connection with the option (the "Tax Date") in the amount necessary
to satisfy any such obligation or (ii) the optionee may satisfy any such
obligation by any of the following means: (A) a cash payment to the Company,
(B) delivery (either actual delivery or by attestation procedures established
by the Company) to the Company of previously owned whole shares of Common
Stock having an aggregate Fair Market Value determined as of the Tax Date,
equal to the amount necessary to satisfy any such obligation, (C) authorizing
the Company to withhold whole shares of Common Stock which would otherwise be
delivered upon exercise of the option having an aggregate Fair Market Value
determined as of the Tax Date, equal to the amount necessary to satisfy any
such obligation, (D) a cash payment by a broker-dealer acceptable to the
Company to whom the optionee has submitted an irrevocable notice of exercise
or (E) any combination of (A), (B) and (C), in each case to the extent set
forth in the Agreement relating to the option. Shares of Common Stock to be
delivered or withheld may not have an aggregate Fair Market Value in excess of
the amount determined by applying the minimum statutory withholding rate. Any
fraction of a share of Common Stock which would be required to satisfy such an
obligation shall be disregarded and the remaining amount due shall be paid in
cash by the optionee.

4.6    Restrictions on Shares.    Each option hereunder shall be subject to the
requirement that if at any time the Company determines that the listing,
registration or qualification of the shares of Common Stock subject to such
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 exercise
of such option or the delivery of shares thereunder, such option shall not be
exercised and such shares shall not be delivered 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 may require that certificates evidencing shares of Common Stock
delivered pursuant to any option hereunder bear a legend indicating that the
sale, transfer or other disposition thereof by the holder is prohibited except
in compliance with the Securities Act of 1933, as amended, and the rules and
regulations thereunder.

4.7    Adjustment.    In the event of any stock split, stock dividend,
recapitalization, reorganization, merger, consolidation, combination, exchange
of shares, liquidation, spin-off or other similar change in capitalization or
event, or any distribution to holders of Common Stock other than a regular
cash dividend, the number and class of securities available under this Plan,
the maximum number and class of securities with respect to which options may
be granted during any calendar year to any person, the number (including on
its date of grant for purposes of determining


                                      41




exercisability pursuant to Section 3.2(b)) and class of securities subject to
each outstanding option, the purchase price per security, and the number and
class of securities subject to each option to be granted to Non-Employee
Directors pursuant to Article III shall be appropriately adjusted by the
Committee, such adjustments to be made in the case of outstanding options
without an increase in the aggregate purchase price. The decision of the
Committee regarding any such adjustment shall be final, binding and
conclusive. If any adjustment would result in a fractional security being (a)
available under this Plan, such fractional security shall be disregarded, or
(b) subject to an option under this Plan, the Company shall pay the optionee,
in connection with the first exercise of the option in whole or in part
occurring after such adjustment, an amount in cash determined by multiplying
(A) the fraction of such security (rounded to the nearest hundredth) by (B)
the excess, if any, of (x) the Fair Market Value on the exercise date over (y)
the exercise price of the option.

4.8      Change in Control.

options shall immediately become exercisable in full and there shall be
substituted for each share of Common Stock available under this Plan, whether or
not then subject to an outstanding option, the number and class of shares into
which each outstanding share of Common Stock shall be converted pursuant to such
Change in Control. In the event of any such substitution, the purchase price per
share of each option shall be appropriately adjusted by the Committee (whose
determination shall be final, binding and conclusive), such adjustments to be
made without an increase in the aggregate purchase price or base price.

         (2) Notwithstanding any provision in this Plan or any Agreement, in the
event of a Change in Control pursuant to Section (b)(1) or (2) below, or in the
event of a Change in Control pursuant to Section (b)(3) or (4) below in

Act, each outstanding option shall be surrendered to the Company by the holder
thereof, and each such option shall immediately be canceled by the Company, and
the holder shall receive, within ten days of the occurrence of a Change in
Control, a cash payment from the Company in an amount equal to the number of
shares of Common Stock then subject to such option, multiplied by the excess, if
any, of (i) the greater of (A) the highest per share price offered to
stockholders of the Company in any transaction whereby the Change in Control
takes place or (B) the Fair Market Value of a share of Common Stock on the date
of occurrence of the Change in Control over (ii) the purchase price per share of
Common Stock subject to the option. The Company may, but is not required to,
cooperate with any person who is subject to Section 16 of the Exchange Act to
assure that any cash payment in accordance with the foregoing to such person is
made in compliance with Section 16 and the rules and regulations thereunder.

                                    Exhibit B


                          EMPLOYEE STOCK PURCHASE PLAN
                          ----------------------------

              1. Purpose. The purpose of the CDW Computer Centers, Inc.
Employee Stock Purchase Plan (the "Plan") is to provide employees of CDW
Computer Centers, Inc., an Illinois corporation (the "Company"), and its
Subsidiary Companies (as defined below) added incentive to remain employed by
such companies and to encourage increased efforts to promote the best
interests of such companies by permitting eligible employees to purchase
shares of common stock, par value $.01 per share, of the Company ("Common
Stock") at below-market prices. The Plan is intended to qualify as an
"employee stock purchase plan" under section 423 of the Internal Revenue Code
of 1986, as amended (the "Code"). For purposes of the Plan, the term
"Subsidiary Companies" shall mean all corporations which are subsidiary
corporations (within the meaning of Section 424(f) of the Code) and of which
the Company is the common parent. The Company and its Subsidiary Companies
that, from time to time, adopt the Plan are sometimes hereinafter called
collectively the "Participating Companies."

              2. Eligibility. Participation in the Plan shall be open to each
employee of the Participating Companies who has been continuously employed by
the Participating Companies for at least 90 consecutive days (an "Eligible
Employee").

              No right to purchase Common Stock hereunder shall accrue under
the Plan in favor of any person who is not an Eligible Employee as of the
first day of a Purchase Period (as defined in Section 3). For purposes of the
Plan, the term "employee" shall not include any individual who performs
services for any of the Participating Companies, pursuant to an agreement
(written or oral) that classifies such individual's relationship with the
Participating Company as other than a common law employee of the Participating
Company, regardless of whether such individual is at any time determined to be
a common law employee of the Participating Company.

              Notwithstanding anything contained in the Plan to the contrary,
no Eligible Employee shall acquire a right to purchase Common Stock hereunder
if (i) immediately after receiving such right, such employee would own 5% or
more of the total combined voting power or value of all classes of stock of
the Company or any Subsidiary Company (including any stock attributable to
such employee under section 424(d) of the Code), or (ii) for any calendar year
such right would permit such employee's aggregate rights to purchase stock
under all employee stock purchase plans of the Company and its Subsidiary
Companies exercisable during such calendar year to accrue at a rate which
exceeds $25,000 of fair market value of such stock for such calendar year.

              Further notwithstanding anything contained in the Plan to the
contrary, the maximum number of shares that may be bought by any Eligible
Employee during any Purchase Period shall not exceed 325, subject to
adjustment in the same manner described in Section 12, in the case of the
occurrence of any of the events described in Section 12.

              3. Effective Date of Plan; Purchase Periods. The Plan shall
become effective on July 1, 2002 or on such later date as may be specified by
the Committee (as defined in Section 11). The Plan shall cease to be effective
unless, within 12 months before or after the date of its adoption by the Board
of Directors of the Company (the "Board"), it has been approved by the
shareholders of the Company.

              A "Purchase Period" shall consist of the three month period
beginning on the effective date and each three month period beginning three
months, six months, nine months and twelve months after the effective date as
well as the three month periods beginning on the anniversaries of such three
month periods and prior to termination of the Plan.

              4. Basis of Participation. (A) Payroll Deduction. Subject to
compliance with applicable rules prescribed by the Committee, each Eligible
Employee shall be entitled to enroll in the Plan as of the first day of any
Purchase Period which begins on or after such employee has become an Eligible
Employee.

              To enroll in the Plan, an Eligible Employee shall make a request
to the Company or its designated agent at the time and in the manner specified
by the Committee, specifying the amount of payroll deduction to be applied to
the compensation paid to the employee by the employee's employer while the
employee is a participant in the Plan. The amount of each payroll deduction
specified in such request for each such payroll period shall be a whole
percentage of a participant's compensation, unless otherwise determined by the
Committee to be a whole dollar amount, in either case not to exceed 15%, or
such lesser percentage as may be determined by the Committee, of the
participant's compensation (before withholding or other deductions) paid to
him or her during the Purchase Period by any of the Participating Companies.
Subject to compliance with applicable rules prescribed by the Committee, the
request shall become effective on the first day of the Purchase Period
following the day the Company or its designated agent receives such request.

              Payroll deductions (and any other amount paid under the Plan)
shall be made for each participant in accordance with such participant's
request until such participant's participation in the Plan terminates, such
participant's payroll deductions are suspended, such participant's request is
revised or the Plan terminates, all as hereinafter provided.

              A participant may change the amount of his or her payroll
deduction effective as of the first day of any Purchase Period by so directing
the Company or its designated agent at the time and in the manner specified by
the Committee. A participant may not change the amount of his or her payroll
deduction effective as of any date other than the first day of a Purchase
Period, except that a participant may elect to suspend his or her payroll
deduction under the Plan as provided in Section 7.

              Payroll deductions for each participant shall be credited to a
purchase account established on behalf of the participant on the books of the
participant's employer or such employer's designated agent (a "Purchase
Account"). At the end of each Purchase Period, the amount in each
participant's Purchase Account will be applied to the purchase of the number
of whole shares of Common Stock determined by dividing such amount by the
Purchase Price (as defined in Section 5) for such Purchase Period. No interest
shall accrue at any time for any amount credited to a Purchase Account of a
participant.

              (b) Other Methods of Participation. The Committee may, in its
discretion, establish additional procedures whereby Eligible Employees may
participate in the Plan by means other than payroll deduction, including, but
not limited to, delivery of funds by participants in a lump sum or automatic
charges to participants' bank accounts. Such other methods of participating
shall be subject to such rules and conditions as the Committee may establish.
The Committee may at any time amend, suspend or terminate any participation
procedures established pursuant to this paragraph without prior notice to any
participant or Eligible Employee.

              5. Purchase Price. The purchase price (the "Purchase Price") per
share of Common Stock hereunder for any Purchase Period (as defined in Section
3) shall be the lesser of 85% of the fair market value of a share of Common
Stock on the first day of such Purchase Period and 85% of the fair market
value of a share of Common Stock on the last day of such Purchase Period. If
such sum results in a fraction of one cent, the Purchase Price shall be
increased to the next higher full cent. For purposes of the Plan, the fair
market value of a share of Common Stock on a given day shall be the closing
transaction price of a share of Common Stock as reported on The NASDAQ Stock
Market on the date as of which such value is being determined or, if there
shall be no reported transactions on such date, on the next preceding date for
which a transaction was reported. In no event, however, shall the Purchase
Price be less than the par value of a share of Common Stock.

              6. Issuance of Stock. The Common Stock purchased by each
participant shall be posted to such participant's Purchase Account as


                                      46




soon as practicable after, and credited to such participant's Purchase Account
as of, the last day of each Purchase Period. Except as provided in Section 7
and Section 8, a participant will be issued his or her shares when his or her
participation in the Plan is terminated, the Plan is terminated or upon
request, but, in the last case, only in denominations of at least 25 shares.

              After the close of each Purchase Period, information will be
made available to each participant regarding the entries made to such
participant's Purchase Account, the number of shares of Common Stock purchased
and the applicable Purchase Price. In the event that the maximum number of
shares of Common Stock are purchased by the participant for the Purchase
Period and cash remains credited to the participant's Purchase Account, such
cash shall be delivered as soon as practicable to such participant. For
purposes of the preceding sentence, the maximum number of shares of Common
Stock that may be purchased by a participant for a Purchase Period shall be
determined under Section 2.

              The Committee may permit or require that shares be deposited
directly with a broker designated by the Committee or to a designated agent of
the Company, and the Committee may use electronic or automated methods of
share transfer. The Committee may require that shares be retained with such
broker or agent for a designated period of time and/or may establish other
procedures to permit tracking of disqualifying dispositions of such shares.

              7. Termination of Participation. (a) Suspension of Payroll
Deductions. A participant may elect at the time and in the manner specified by
the Committee to suspend his or her participation in the Plan, provided such
election is received by the Company or its designated agent prior to the date
specified by the Committee for suspension of participation with respect to the
Purchase Period for which such suspension is to be effective. Upon any
suspension of participation, the participant's payroll deductions shall cease,
and if the participant elects, the cash credited to such participant's
Purchase Account on the date of such suspension shall be delivered as soon as
practicable to such participant. If the participant does not elect to receive
such cash, such cash shall be applied to the purchase of shares of Common
Stock, as described in Sections 4, 5 and 6 hereof. A participant who elects to
suspend participation in the Plan shall be permitted to resume participation
in the Plan by making a new request to participate at the time and in the
manner described in Section 4 hereof.

              (b) Termination of Participation. If the participant dies,
terminates employment with the Participating Companies for any reason, or
otherwise ceases to be an Eligible Employee, such participant's participation
in the Plan shall immediately terminate. Upon such terminating event, the cash
credited to such participant's Purchase Account on the date of such
termination shall be delivered as soon as practicable to such participant or
his or her legal representative, as the case may be, and certificates for the
number of full shares of Common Stock held, for his or her benefit and the
cash equivalent for any fractional share so held, shall be delivered to the
participant or his or her legal representative, as the case may be, as soon as
practicable after such termination. Such cash equivalent shall be determined
by multiplying the fractional share by the fair market value of a share of
Common Stock on the day immediately preceding such election to receive such
shares determined as provided in Section 5.

              8. Termination or Amendment of the Plan. The Company, by action
of the Board, may terminate the Plan at any time, in which case notice of such
termination shall be given to all participants, but any failure to give such
notice shall not impair the effectiveness of the termination.

              Without any action being required, the Plan shall terminate in
any event when the maximum number of shares of Common Stock to be sold under
the Plan (as provided in Section 12) has been purchased. Such termination
shall not impair any rights which under the Plan shall have vested on or prior
to the date of such termination. If at any time the number of shares of Common
Stock remaining available for purchase under the Plan are not sufficient to
satisfy all then-outstanding purchase rights, the Board or Committee may
determine an equitable basis of apportioning available shares of Common Stock
among all participants.


                                       47



              The Committee may amend the Plan from time to time in any
respect for any reason; provided, however, no such amendment shall (a)
materially adversely affect any purchase rights outstanding under the Plan
with respect to the Purchase Period in which such amendment is to be effected,
(b) increase the maximum number of shares of Common Stock which may be
purchased under the Plan, (c) decrease the Purchase Price of a share of Common
Stock for any Purchase Period below the lesser of 85% of the fair market value
thereof on the first day of such Purchase Period and 85% of such fair market
value on the last day of such Purchase Period or (d) adversely affect the
qualification of the Plan under section 423 of the Code.

              Upon termination of the Plan, one or more certificates for the
number of full shares of Common Stock held for each participant's benefit and
the cash equivalent of any fractional share so held, determined as provided in
Section 7 shall be delivered to such participant as soon as practicable after
the Plan terminates, and, except as otherwise provided in Section 14, the
cash, if any, credited to the such participant's Purchase Account, shall also
be distributed to such participant as soon as practicable after the Plan
terminates.

              9. Non-Transferability. Rights acquired under the Plan are not
transferable and may be exercised only by a participant.

              10. Shareholder's Rights. No Eligible Employee or participant
shall by reason of the Plan have any rights of a shareholder of the Company
until he or she shall acquire a share of Common Stock as herein provided.

              11. Administration of the Plan. The Plan shall be administered
by a committee (the "Committee") designated by the Board. In addition to the
power to amend the Plan pursuant to Section 8, the Committee shall have full
power and authority to: (i) interpret and administer the Plan and any
instrument or agreement entered into under the Plan; (ii) establish such rules
and regulations and appoint such agents as it shall deem appropriate for the
proper administration of the Plan; and (iii) make any other determination and
take any other action that the Committee deems necessary or desirable for
administration of the Plan. Decisions of the Committee shall be final,
conclusive and binding upon all persons, including the Company, any
participant and any other employee of the Company.

         The Plan shall be administered so as to ensure that all participants
have the same rights and privileges as are provided by section 423(b)(5) of the
Code.

              12. Maximum Number of Shares. The maximum number of shares of
Common Stock which may be purchased under the Plan is 500,000, subject to
adjustment as hereinafter set forth. Shares of Common Stock sold hereunder may
be treasury shares, authorized and unissued shares, shares purchased in the
open market (on an exchange or in negotiated transactions) or any combination
thereof. If the Company shall, at any time after the effective date of the
Plan, change its issued Common Stock into an increased number of shares, with
or without par value, through a stock dividend or a stock split, or into a
decreased number of shares, with or without par value, through a combination
of shares, then, effective with the record date for such change, the maximum
number of shares of Common Stock which thereafter may be purchased under the
Plan shall be the maximum number of shares which, immediately prior to such
record date, remained available for purchase under the Plan proportionately
increased, in case of such stock dividend or stock split, or proportionately
decreased in case of such combination of shares.

              13. Miscellaneous. Except as otherwise expressly provided
herein, (i) any request, election or notice under the Plan from an Eligible
Employee or participant shall be transmitted or delivered to the Company or
its designated agent and, subject to any limitations specified in the Plan,
shall be effective when so delivered and (ii) any request, notice or other
communication from the Company or its designated agent that is transmitted or
delivered to Eligible Employees or participants shall be effective when so
transmitted or delivered. The Plan, and the Company's obligation to sell and
deliver shares of Common Stock hereunder, shall be subject to all applicable
federal and state laws, rules and regulations, and to such approval by any
regulatory or governmental agency as may, in the opinion of counsel for the
Company, be required.


                                      48




              14. Change in Control. In the event of any Change in Control of
the Company, as defined below, the then current Purchase Period shall
thereupon end, the Committee, in its sole discretion, shall either direct that
the cash credited to all participants' Purchase Accounts be applied to
purchase shares pursuant to Sections 4, 5 and 6 or that such cash be returned
to participants and the Plan shall immediately thereafter terminate. For
purposes of this Section 14, "Change in Control" shall have the same meaning
as the definition of "Change in Control" set forth in the CDW 2000 Incentive
Stock Option Plan, as amended from time to time, or any successor plan
thereto.
