                              EMPLOYMENT AGREEMENT

      THIS EMPLOYMENT AGREEMENT, dated this 9th day of February to be effective
as of February 21, 2005 (the "Effective Date"), is by and between Insight
Enterprises, Inc., a Delaware corporation ("Company"), and Gary M. Glandon
("Employee").

      In consideration of the mutual agreements hereinafter set forth and other
good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, Company and Employee hereby agree as follows:

      1. POSITION. Company hereby employs Employee as its Executive Vice
President - Human Resources, and Employee hereby accepts and agrees to such
employment. Employee's duties and authority shall be such executive and
managerial duties as the Chief Executive Officer of Company shall reasonably
determine from time to time. Executive will devote full time on behalf of
Company, reasonable absences because of illness or personal and family
exigencies excepted. Employee agrees to perform, faithfully and to the best of
Employee's ability, the duties that may be required of Employee.

      2. COMPENSATION. Company shall pay Employee a "Base Salary" at the rate of
$215,000.00 per year. The Base Salary shall be payable as nearly as possible in
equal semi-monthly installments or in such other installments as are customary
from time to time for Company's executives. The Base Salary may be adjusted from
time to time in accordance with the procedures established by Company for salary
adjustments for executives. Employee shall be entitled to an annual incentive
bonus. The amount if any, of the incentive bonus shall be based on the extent to
which Employee or Company, or both, achieve objectives set by the Chief
Executive Officer of Company. Employee shall be entitled to participate in other
benefit plans made available generally to employees of Company from time to
time, including but not limited to, any savings plan, life insurance plan and
health insurance plan, subject to any restrictions specified in, or amendments
made to, such plans.

      3. DEFINITIONS.

            a. ENGAGED IN A COMPETING BUSINESS. Employee shall be deemed to be
"Engaged in a Competing Business" if, in any capacity, including proprietor,
shareholder, partner, officer, director or employee, Employee engages or
participates, directly or indirectly, in the operation, ownership or management
of the activity of any proprietorship, partnership, company or other business
entity which activity is competitive with the then actual business in which
Company is engaged on the date of, or any business contemplated by Company's
business plan in effect on the date of notice of, the termination of Employee's
employment by Company. Nothing in this Agreement is intended to limit Employee's
ability to own equity in a public company constituting less than one percent
(1%) of the outstanding equity of such company, so long as Employee is not
actively engaged in the management thereof.

            b. RESTRICTED TERRITORY. Employee and Company understand and agree
that Company's business is not geographically restricted and is unrelated to the
physical location of

<PAGE>

Company facilities or the physical location of any Competing Business, due to
extensive use of the Internet, telephones, facsimile transmissions and other
means of electronic information and product distribution. Accordingly, Company
has a protectable business interest in, and the parties intend the Restricted
Territory to encompass, each and every location from which Employee could engage
in Competing Business in any country, state, province, county or other political
subdivision in which Company has customers, employees, suppliers, distributors
or other business partners or operations. If, but only if, this Restricted
Territory is held to be invalid on the ground that it is unreasonably broad, the
Restricted Territory shall include each location from which Employee can conduct
business in any of the following locations: the United States of America
(including each state in which Company conducts sales or operations); Canada;
the United Kingdom; and each political subdivision of each of the foregoing
countries. If, but only if, this Restricted Territory is held to be invalid on
the grounds that it is unreasonably broad, then the Restricted Territory shall
be the United States (including each state in which Company conducts sales or
operations), Canada, the United Kingdom, any other country in which Company
conducts sales or operations and each political subdivision of each of the
foregoing countries in which Company can articulate a legitimate protectable
business interest.

      4. CONFIDENTIALITY. Employee covenants and agrees to hold in strictest
confidence, and not disclose to any person, firm or company, without the express
written consent of Company, any and all of Company's confidential data,
including, but not limited to, information and documents concerning Company's
business, customers, suppliers, market methods, files, trade secrets or other
"know-how" or techniques or information not of a published nature or generally
known (for the duration they are not published or generally known) which shall
come into Employee's possession, knowledge, or custody concerning the business
of Company, except as such disclosure may be required by law or in connection
with Employee's employment hereunder or except as such matters may have been
known to Employee at the time of Employee's employment by Company. This covenant
and agreement of Employee shall survive this Agreement and continue to be
binding upon Employee after the expiration or termination of this Agreement,
whether by passage of time or otherwise so long as such information and data
shall be treated as confidential by Company. Because of Employee's knowledge of
and participation in executive issues and decisions, for purposes of this
Section 4, the term "Company" shall mean Company and all of the direct and
indirect subsidiaries of Company.

      5. COVENANT NOT TO COMPETE. In consideration of Company's agreements
contained herein, the payments to be made by it to Employee pursuant hereto and
Employee's access to the confidential information of Company, Employee agrees
that, for a period of one (1) year following the termination of Employee's
employment with Company, Employee will not, without prior written consent of
Company, be Engaged in a Competing Business (as defined above) in the Restricted
Territory (as defined above).

      6. COVENANT NOT TO SOLICIT CUSTOMERS OF COMPANY. Employee recognizes that
Company's customers are valuable and proprietary resources of Company.
Accordingly, Employee agrees that for a period of one (1) year following the
termination of Employee's employment with Company, Employee will not directly or
indirectly solicit any client or potential client of Company with whom Employee
had contact or for whose account Employee worked within the last twelve (12)
months of Employee's employment with Company (or the

                                       2
<PAGE>

period of Employee's employment if less than twelve (12) months), with the
purpose, effect or potential of: (i) selling (or assisting another person's
selling) or providing such client products or services that are the same,
similar, or related to products or services provided by Company at that time; or
(ii) in any way reducing the amount of business such client transacts with
Company.

      7. COVENANT NOT TO SOLICIT EMPLOYEES. Employee agrees that for a period of
one (1) year following the termination of Employee's employment with Company,
Employee will not directly or indirectly solicit, hire or engage employees of
Company who would have the skills and knowledge necessary to enable or assist
efforts by Employee to be Engaged in a Competing Business.

      8. REASONABLENESS; REMEDIES. Employee acknowledges and agrees that a
breach by Employee of the provisions of Section 4, 5, 6 or 7, or any combination
thereof, will constitute such damage as will be irreparable and the exact amount
of which will be impossible to ascertain and, for that reason, agrees that
Company will be entitled to an injunction to be issued by any court of competent
jurisdiction restraining and enjoining Employee from violating the provisions of
such Section or Sections. The right to an injunction shall be in addition to and
not in lieu of any other remedy available to Company for such breach or
threatened breach, including the recovery of damages from Employee. Employee
expressly acknowledges and agrees that: (a) the restrictive covenants in
Sections 4, 5, 6 and 7 are reasonable as to time and geographical area and do
not place any unreasonable burden upon Employee; (b) the general public will not
be harmed as a result of enforcement of the restrictive covenants in Sections 4,
5, 6 and 7; and (c) Employee understands and hereby agrees to each and every
term and condition of the restrictive covenants in Sections 4, 5, 6 and 7.
Employee also expressly acknowledges and agrees that Employee's covenants and
agreements in this Section 8 shall survive this Agreement and continue to be
binding upon Employee after the expiration or termination of this Agreement,
whether by passage of time or otherwise.

      9. RESTRICTIONS; TRADE SECRETS. Employee represents and warrants that
Employee has not entered into any agreement, whether express, implied, oral, or
written, that poses an impediment to Employee's employment by Company including
Employee's compliance with the terms of this Agreement. In particular, Employee
is not subject to a valid, pre-existing non-competition agreement which
prohibits Employee from fulfilling Employee's job duties under this Agreement,
and no restrictions or limitations exist respecting Employee's ability to
perform fully Employee's obligations to Company, including Employee's compliance
with the terms of this Agreement. Employee agrees not to copy, refer to, or in
any way use, information that is proprietary to any third party (including any
previous employer) in performing his job duties under this Agreement. Employee
represents and warrants that Employee has not improperly taken any documents,
listings, hardware, software, discs, or any other tangible medium that embodies
proprietary information from any third party, and that Employee does not intend
to copy, refer to, or in any way use, information that is proprietary to any
third party in performing duties for Company.

      10. VOLUNTARY TERMINATION OF EMPLOYMENT BY EMPLOYEE. Employee shall have
the right to terminate his employment with Company at any time. Employee agrees
to provide

                                       3
<PAGE>

Company with two (2) weeks prior written notice of any such termination.
Company's obligation to pay base salary to Employee shall cease as of Employee's
last day of work.

      11. INVOLUNTARY TERMINATION OF EMPLOYMENT BY COMPANY FOR CAUSE. Company
may terminate Employee's employment at any time for Cause. As used in this
Section 11, a termination for "Cause" shall mean a termination of employment for
one or more of the following reasons: (1) the misappropriation (or attempted
misappropriation) of any funds or property of Company; (2) the conviction of, or
the entering of a guilty plea or plea of no contest with respect to, a felony or
a misdemeanor which involves moral turpitude or a fraudulent act; (3) willful or
repeated neglect of duties; (4) acts of material dishonesty or insubordination
toward Company; or (5) material breach of this Agreement. The Chief Executive
Officer of Company or a duly appointed agent shall conclusively determine the
existence of Cause. If Company terminates Employee's employment for Cause,
Company's obligation to pay base salary to Employee shall cease as of Employee's
last day of work as specified by Company in its notice to Employee of the
termination for Cause. Any termination improperly characterized under this
Section 11 (such as in the case where "Cause" is found not to exist) shall be
reclassified as an "Involuntary Termination Without Cause." In such event,
Employee's sole and exclusive remedy shall be the payment of one (1) year base
salary and pro-rated bonus, if any, under the then current compensation plan,
through the effective date of termination of Employee's employment, provided
Employee executes and delivers to Company (if requested by Company) a release of
any and all claims Employee may have against Company, which release shall be
satisfactory, in both form and substance, to Company.

      12. INVOLUNTARY TERMINATION OF EMPLOYMENT BY COMPANY WITHOUT CAUSE.
Company may also terminate Employee's employment without cause (i.e., for any
reason or no reason) by providing Employee with written notice of such
termination. Employee's employment and this Agreement shall terminate as of the
date specified in said notice. If Employee's employment is terminated pursuant
to this Section 12, Company shall continue to pay Employee his base salary for a
period of one (1) year following the effective date of the termination of
Employee's employment and pro-rated bonus, if any, under the then current
compensation plan, through the effective date of termination of Employee's
employment. As a condition to any payment called for by this Section 12, Company
may require Employee to execute a release of any and all claims Employee may
have against Company, which release shall be satisfactory, in both form and
substance, to Company.

      13. CONFIDENTIALITY OF AGREEMENT. By executing this Agreement, Employee
hereby agrees not to disclose the terms of this Agreement to anyone not employed
by Company, except for legal advisors, tax advisors or as may be required by
law.

      14. SECTION 16 REPORTING. If, at the time Employee's employment is
terminated for any reason, Employee is subject to the reporting requirements of
Section 16(a) of the Securities Exchange Act of 1934, Employee will provide to
Company a written representation in a form acceptable to Company that all
reportable pre-termination securities transactions relating to Employee have
been reported.

                                       4
<PAGE>

      15. ASSIGNMENT. This Agreement is personal in its nature, and Employee may
not assign or transfer this Agreement or any rights or obligations hereunder.

      16. WAIVER. Failure to insist upon strict compliance with any of the
terms, covenants or conditions hereof shall not be deemed a waiver of such term,
covenant or condition, nor shall any waiver or relinquishment of, or failure to
insist upon strict compliance with, any right or power hereunder at any one or
more times be deemed a waiver or relinquishment of such right or power at any
other time or times.

      17. ENTIRE AGREEMENT. This Agreement embodies the entire agreement of the
parties regarding the matters within its scope and may be modified only in
writing, duly executed by Employee and a duly authorized representative of
Company.

      18. SEVERABILITY. In the event that a court of competent jurisdiction
determines that any portion(s) of this Agreement is in violation of law or
public policy, then only the portion(s) of this Agreement which violate such law
or public policy shall be stricken. All portions of this Agreement which do not
violate any law or public policy shall continue in full force and effect.
Further, any court order striking any portion of this Agreement shall modify the
stricken terms to give as much effect as possible to the intentions of the
parties under this Agreement.

      19. ARBITRATION. The parties agree that any and all disputes arising out
of the terms of this Agreement, their interpretation, or Employee's employment
or compensation, shall be subject to binding arbitration in Maricopa County,
Arizona, before the American Arbitration Association under its National Rules
for the Resolution of Employment Disputes. The parties agree that the prevailing
party in any arbitration shall be entitled to injunctive relief in any court of
competent jurisdiction to enforce the arbitration award.

      20. GOVERNING LAW. This Agreement shall be governed by and construed in
accordance with the laws of the State of Arizona, notwithstanding any Arizona or
other conflict-of-law provisions to the contrary.

      IN WITNESS WHEREOF, the parties have executed and delivered this Agreement
on the date first above written.
