                                                                    EXHIBIT 10.8

                              EMPLOYMENT AGREEMENT

This Employment Agreement (the "Agreement") is entered into and effective as of
April 25, 2002 between Comark, Inc., an Illinois corporation ("Company"), and
Michael V. Wise ("Executive").

                                 R E C I T A L S

Company is a wholly owned subsidiary of Insight Enterprises, Inc. ("Parent").
Executive is currently employed by Company in the position of Senior
Vice-President and Chief Operating Officer. Company has decided to offer
Executive an employment agreement, the terms and provisions of which are set
forth below.

NOW, THEREFORE, IT IS HEREBY MUTUALLY AGREED AS FOLLOWS:

1.    TERMS OF AGREEMENT

(a)   Replacement of Previous Agreements. When this Agreement becomes effective
      on April 25, 2002, it will replace all previous employment agreements
      between Executive and Company and/or its affiliates for all purposes. The
      consideration for this Agreement and the termination of such previous
      agreements is solely as stated in this Agreement and neither party shall
      have any further rights or duties under such previous agreements. The
      foregoing shall not diminish Executive's right, title and interest,
      pursuant to the terms of the Comark, Inc. Equity Incentive/Employment
      Agreement between Executive and Company dated October 13, 1999 (the
      "Equity Agreement"), to payment of his "Account" (as that term is defined
      in the Equity Agreement) as vested on April 25, 2002.

(b)   Initial Term. Executive shall be employed by Company for the duties set
      forth in Section 2 for a one-year term, commencing as of April 25, 2002
      and ending on April 25, 2003 (the "Initial Term"), unless sooner
      terminated in accordance with the provisions of this Agreement.

(c)   Renewal Term; Employment Period Defined. On each successive day after the
      commencement of the Initial Term, without further action on the part of
      Company or Executive, this Agreement shall be automatically renewed for a
      new one-year term dated effective and beginning upon each such successive
      day (the "Renewal Term"); provided, however, that Company may notify
      Executive, or Executive may notify Company, at any time, that there shall
      be no renewal of this Agreement, and in the event of such notice, neither
      party shall be under any obligation to renew or extend this Agreement. The
      period of time commencing as of the date hereof and ending on the
      effective date of the termination of employment of Executive under this or
      any successor Agreement shall be referred to as the "Employment Period."

2.    POSITION AND DUTIES

(a)   Job Duties. Company does hereby employ, engage and hire Executive to serve
      in an executive capacity, and Executive does hereby accept and agree to
      such employment, engagement, and hiring. Executive's duties and authority
      during the Employment Period shall be such executive duties as Parent's
      President (the "President") shall reasonably determine from time to time.
      Executive's initial title shall be Chief Operating Officer of Company and
      Co-President of Insight Services Corporation ("ISC"), and his initial
      duties shall include responsibility for the day-to-day

                                       1
<PAGE>
                                                                    CONFIDENTIAL

      operations of Company and of ISC and their operating subsidiaries, and for
      certain other of Parent's subsidiaries as directed by the President. Such
      title and duties may be changed from time to time by the President. In the
      absence of the President, Parent's Chief Executive Officer (the "CEO") may
      assume the President's role under this Agreement, and in the absence of
      the CEO the Parent's Board of Directors (the "Board") may assume such
      role. Executive will devote substantially all of his working time and
      effort to his duties on behalf of Company, reasonable absences because of
      illness, vacation, and personal and family exigencies excepted.

(b)   Best Efforts. Executive agrees that at all times during the Employment
      Period he will faithfully, and to the best of his ability, experience and
      talents, perform the duties that may be required of and from him and
      fulfill his responsibilities hereunder pursuant to the express terms
      hereof. Executive's ownership of, or participation (including any board
      memberships) in, any entity (other than Company ) must be disclosed to the
      Board; provided, however, that Executive need not disclose any equity
      interest held in any public company or any private company that is not
      engaged in a Competing Business as defined in Section 10 of this Agreement
      when such interest constitutes less than one percent (1.0%) of the issued
      and outstanding equity of such public or private company.

3.    COMPENSATION

(a)   Base Salary. Company shall pay Executive a "Base Salary" in consideration
      for Executive's services to Company at the rate of $300,000 per annum. 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, provided that the Base Salary shall not
      be reduced.

(b)   Incentive Compensation.

      (1)   Executive shall also be permitted to participate in such incentive
            compensation plans as are adopted by the Board or Company from time
            to time. Beginning on the date hereof and continuing through the
            Employment Period, Executive shall be entitled to an incentive
            bonus, calculated and payable quarterly, equal to one and 65/100ths
            percent (1.65%) of the combined Net Earnings (as defined below) of
            Company and ISC (collectively, the "Business"), provided that the
            Net Earnings exceed the Minimum Amount (as defined below) for the
            applicable fiscal quarter. Company and Executive understand and
            agree that Company's business shall include all corporate sales
            divisions of Company and Insight Direct USA, Inc. ("Insight"), and
            that ISC's business shall include all services sales divisions of
            Company and Insight. Furthermore, Company and Executive understand
            and agree that the Business will not include any small- to
            medium-sized business (SMB) sales divisions or public sector sales
            divisions of either Company or Insight, which sales divisions will
            be moved into other subsidiaries of Parent.

      (2)   For purposes of calculating Executive's incentive bonus pursuant to
            this Subsection (b), "Net Earnings" shall mean the net earnings of
            the Business calculated in accordance with accounting principles
            generally accepted in the United States (US GAAP). For the avoidance
            of doubt, Net Earnings shall be calculated after deducting (i) the
            "holding company allocation", (ii) Interest (as defined below),
            (iii) taxes and (iv) any incentive bonus amounts for Executive and
            other executives of the Business. The "holding company allocation"
            shall mean the monthly allocation of Parent's and affiliate
            companies' expenses allocated to the Business by Parent and its
            affiliate companies in a

                                       2

                                                                    CONFIDENTIAL

            manner consistent with Parent's customary practices, excluding any
            allocation of interest income associated with the Purchase Debt (as
            defined below). "Interest" shall mean interest charged on external
            and intercompany debt, excluding interest charged on debt (including
            both external and intercompany) totaling approximately $150 million
            ("Purchase Debt") created in conjunction with the acquisition of
            Comark, Inc. by Insight Enterprises, Inc. The amounts payable
            pursuant to this Subsection 3(b) shall be paid on or before thirty
            (30) days after the public financial reporting by Parent at the end
            of the applicable fiscal quarter. For purposes of this Subsection
            3(b), the term "Minimum Amount" means an amount equal to eighty
            percent (80%) of the average of the Net Earnings for the immediately
            preceding four fiscal quarters ended prior to the applicable fiscal
            quarter. Notwithstanding the foregoing, the Net Earnings during the
            second calendar quarter of 2001 shall be deemed to be $4,591,000,
            during the third calendar quarter of 2001 shall be $7,641,000,
            during the fourth calendar quarter of 2001 shall be $10,655,000,
            during the first calendar quarter of 2002 shall be $4,741,000, and
            during the second calendar quarter of 2002 shall be the Net Earnings
            for May and June 2002 only (i.e., excluding April 2002) multiplied
            by a factor of 3/2. Notwithstanding any provision in this Subsection
            3(b) to the contrary, Executive's incentive bonus for the second
            calendar quarter of 2002 shall be calculated pursuant to the
            foregoing provisions and then multiplied by a factor of 2/3, due to
            the fact that the term of this Agreement excludes most of April
            2002.

      (3)   If upon final presentation of consolidated financial statements to
            Parent by Parent's outside Certified Public Accountants, the
            combined "net earnings" of the Business requires adjustment for any
            period for which the Executive received an incentive bonus
            hereunder, then, within thirty (30) days after such presentation,
            Company or Executive, as the case may be, shall pay to the other the
            amount necessary to cause the net amount of incentive bonus paid to
            be the proper amount after adjustment; provided that if Executive
            shall pay Company pursuant to the provisions of this clause (3),
            then the amount the Executive shall pay will be reduced by the taxes
            withheld by Company attributable to such amount ("Withheld
            Portion"), and the Company shall apply the Withheld Portion toward
            Company's withholding obligations with regard to any subsequent
            payments of Base Salary and incentive compensation made pursuant to
            Sections 3(a) and 3(b) or, at Company's option, Executive shall
            repay to Company any remaining amount due within seven business days
            of Company's written request therefor. Notwithstanding the
            foregoing, if the presentation of consolidated financial statements
            referenced above occurs more than five (5) years after the last day
            of the period to which the original incentive bonus at issue
            applied, no adjustments may be made pursuant to this subsection.

(c)   Incentive and Benefit Plans. Executive will be entitled to participate in
      those incentive compensation and benefit plans reserved for Company's
      executives, including any such plans offered by Parent to employees of its
      subsidiaries, including any stock option plans, in accordance with the
      terms of such compensation and benefit plans. Additionally, Executive
      shall be entitled to participate in any other benefit plans sponsored by
      Company or offered by Parent to employees of its subsidiaries, including
      any savings plan, life insurance plan and health insurance plan available
      generally to employees of Company from time to time, subject to any
      restrictions specified in, or amendments made to, such plans.

(d)   Vacation. Executive shall be entitled to four (4) weeks vacation during
      the calendar year, and such additional vacation time as the Board shall
      approve, with such vacation to be scheduled and taken in accordance with
      Company's standard vacation policies, but this provision is not intended

                                       3
<PAGE>
                                                                    CONFIDENTIAL

      to interfere with or limit Executive's discretion to determine the
      appropriate time to be devoted to his duties hereunder.

(e)   Stock Options. Concurrently herewith, Executive is being granted 100,000
      stock options under Parent's 1998 Long-Term Incentive Plan, at a strike
      price to equal the closing share price of Parent's stock on the date of
      grant and vesting at 50,000 shares on April 25, 2003 and 50,000 shares on
      April 25, 2004, such options to be evidenced by and subject to the
      provisions in the award agreements being delivered concurrently.

4.    BUSINESS EXPENSES

Company will reimburse Executive for any and all necessary, customary and usual
expenses which are incurred by Executive on behalf of Company, provided
Executive provides Company with receipts to substantiate the business expense in
accordance with Company's policies or otherwise reasonably justifies the expense
to Company.

5.    DEATH OR DISABILITY

(a)   Death. This Agreement shall terminate upon Executive's death. Executive's
      estate shall be entitled to receive the Base Salary due through the date
      of his death and any incentive compensation payable for quarters ended
      prior to Executive's death, but no Base Salary or other payment or benefit
      will be payable after death except as expressly provided elsewhere in this
      Agreement. The determination of any bonuses or incentive compensation to
      be payable for quarters ending following Executive's death will be made in
      accordance with the provisions of any incentive compensation program,
      practice, or policy in which Executive participates at the time of
      Executive's death. If there is no written incentive compensation program,
      policy, or practice in effect at the time of Executive's death, Company,
      in the exercise of its discretion, may elect to pay to Executive's estate
      a portion of the incentive compensation to which Executive would have been
      entitled (had Executive not died) for the year in which this Agreement
      terminated due to Executive's death.

(b)   Disability. The Company may terminate this Agreement upon written notice
      to Executive in the event of Executive's "Disability". For purposes of
      this Agreement, Executive shall be deemed to have a "Disability" if, for a
      minimum continuous period of six (6) months, Executive meets the
      definition of "Disability" used to determine Executive's right to benefits
      pursuant to the long-term disability insurance policy in place for
      Company's exempt employees at the end of such six-month period and such
      disability occurs due to a physical or mental injury or illness that
      occurs while Executive is actively employed by Company. Notwithstanding
      the foregoing, Executive shall be deemed to have a "Disability" if the
      sole factor preventing Executive from otherwise meeting the definition of
      "Disability" set forth above is Executive's employment and/or receipt of
      compensation pursuant to this Agreement. If this Agreement is terminated
      due to Executive's Disability, Executive shall receive the severance
      compensation called for by Section 6B(b). Company may not terminate this
      Agreement for Cause (see Section 6A) due solely to Executive's breach of
      Section 2 if such breach is the result of Executive's Disability.

6A.   TERMINATION BY COMPANY FOR CAUSE

(a)   Termination for Cause. Company may terminate this Agreement at any time
      during the Initial Term or any Renewal Terms for "Cause" upon written
      notice to Executive. If Company terminates this Agreement for "Cause,"
      Executive's Base Salary shall immediately cease, and Executive shall not
      be entitled to severance payments, incentive compensation payments or any

                                       4
<PAGE>
                                                                    CONFIDENTIAL

      other payments or benefits pursuant to this Agreement, except for any
      vested rights pursuant to any benefit plans in which Executive
      participates including Executive's stock options in Parent, any accrued
      compensation, any accrued vacation pay and similar items. For purposes of
      this Agreement, the term "Cause" shall mean the termination of Executive's
      employment by Company for one or more of the following reasons:

      (1)   The criminal conviction for any felony involving theft or
            embezzlement from Company or any affiliate;

      (2)   The criminal conviction for any felony involving moral turpitude
            that reflects adversely upon the standing of Company in the
            community;

      (3)   The criminal conviction for any felony involving fraud committed
            against Company, any affiliate or any individual or entity that
            provides goods or services to, receives goods or services from or
            otherwise deals with Company or any affiliate;

      (4)   Acts by Executive that constitute repeated and material violations
            of this Agreement, any written employment policies of Company, or
            any written directives of Company. A violation will not be
            considered to be "repeated" unless such violation has occurred more
            than once and after receipt of written notice from Company of such
            violation; or

      (5)   Failure to fully cooperate in any investigation by Company or
            Parent.

(b)   Determination of No Cause. If Company terminates Executive for Cause, and
      it is later determined at the conclusion of the Dispute Resolution process
      provided in Section 11 of this Agreement that Cause did not exist, Company
      will pay Executive the amount he would have received under this Agreement
      if his employment had been terminated by Company without Cause, plus
      interest at the Prime Rate published by the Wall Street Journal on the
      date of termination. Such payments and interest shall be calculated as of
      the effective date of the initial termination. Payment shall be made
      within fifteen (15) days after such later determination is made.

(c)   Termination by Executive without Good Reason. If Executive terminates his
      employment without Good Reason as that term is defined in Subsection 7(b),
      the consequences under this Agreement shall be identical to those of a
      termination for Cause.

(d)   Incentive Compensation. Executive shall not be entitled to receive any
      incentive compensation payments for the fiscal quarter in which his
      employment is terminated for Cause or any later quarters.

(e)   Other Plans. Except to the extent specified in this Section 6A including
      this Subsection (e), termination of Executive's employment under this
      Agreement shall not affect Executive's participation in, distributions
      from, and vested rights under any employee benefit plan of Company, which
      will be governed by the terms of those respective plans, in the event of
      Executive's termination of employment.

6B.   TERMINATION BY COMPANY WITHOUT CAUSE

(a)   Termination without Cause. Company also may terminate this Agreement at
      any time during the Initial Term or Renewal Terms without Cause. If
      Company terminates this Agreement pursuant to this Subsection, Company
      shall provide Executive with ninety (90) days advance written

                                       5
<PAGE>
                                                                    CONFIDENTIAL

      notice. This Agreement shall continue during such notice period. The
      termination of this Agreement shall be effective on the ninetieth (90th)
      day following the day on which the notice is given. Company may, at its
      discretion, place Executive on a paid administrative leave during all or
      any part of said notice period. During the administrative leave, Company
      may bar Executive's access to Company's offices or facilities if
      reasonably necessary to the smooth operation of Company, or may provide
      Executive with access subject to such reasonable terms and conditions as
      Company chooses to impose.

(b)   Severance Compensation. Should Executive's employment by Company be
      terminated without Cause, Executive shall receive as a lump sum
      immediately upon such termination the total amount of his Base Salary for
      the remainder of the Initial Term or current Renewal Term, as applicable,
      determined as if the employment of Executive had not been terminated prior
      to the end of such term and as if Executive had continued to perform all
      of his obligations under this Agreement and as an employee, officer and/or
      director of Company. Except as otherwise provided herein, Executive shall
      have no duty to mitigate damages in order to receive the severance
      compensation described by this Subsection, and the severance compensation
      shall not be reduced or offset by other income, payments or profits
      received by Executive from any source.

(c)   Incentive Compensation. If Executive is terminated without Cause,
      Executive shall receive as a lump sum immediately upon such termination
      incentive compensation for the number of quarters remaining in the Initial
      Term or latest Renewal Term, with the amount per quarter equal to the
      average bonus paid during the four quarters immediately preceding the date
      of notice of termination as if Executive had continued to perform all of
      his obligations under this Agreement and as an employee of Company. Except
      as otherwise provided herein, Executive shall have no duty to mitigate
      damages in order to receive the incentive compensation described by this
      Subsection and the incentive compensation shall not be reduced or offset
      by other income, payments or profits received by Executive from any
      source.

(d)   Other Plans. Except to the extent specified in this Section 6B including
      this Subsection (d), termination of this Agreement shall not affect
      Executive's participation in, distributions from, and vested rights under
      any employee benefit plan of Company, which will be governed by the terms
      of those respective plans, in the event of Executive's termination of
      employment. If Executive is terminated without Cause, then Executive shall
      become fully vested under any and all stock bonus and stock option plans
      and agreements in which Executive had an interest, vested or contingent.
      If applicable law or the terms of such plan(s) prohibit such vesting, then
      Company shall pay Executive an amount equal to the value of the benefits
      and rights that would have, but for such prohibition, been vested. Except
      as otherwise provided herein, Executive shall have no duty to mitigate
      damages in order to receive the compensation described by this Subsection
      and the compensation shall not be reduced or offset by other income,
      payments or profits received by Executive from any source.

(e)   Example. For example, if Company were to provide notice to Executive of
      Termination without Cause on January 1, 2003, then the Employment Period
      would end ninety days thereafter, on April 1, 2003, and Company would pay
      to Executive in a lump sum payment immediately thereafter the sum of an
      amount equal to (i) Executive's Base Salary for the next one (1) year
      totaling $300,000 (assuming the Base Salary was at that time $300,000)
      plus (ii) the incentive compensation for four fiscal quarters computed as
      stated above. Additionally, on April 1, 2003 Executive would become fully
      vested in all Company stock bonus and stock option plans and agreements in
      which Executive had an interest.

7.    TERMINATION BY EXECUTIVE

(a)   General. Executive may terminate this Agreement at any time, with or
      without "Good Reason." If Executive terminates this Agreement without Good
      Reason, Executive shall provide Company with ninety (90) days advance
      written notice. If Executive terminates this Agreement with Good Reason,
      Executive shall provide Company with thirty (30) days advance written
      notice.

(b)   Good Reason Defined. For purposes of this Agreement, "Good Reason" shall
      mean and include each of the following (unless Executive has expressly
      agreed to such event in a signed writing):

      (1)   The assignment to Executive of duties which are not executive in
            nature, except in connection with the termination of this Agreement
            for Cause, Executive's death or Disability, termination by Executive
            other than for Good Reason, or the expiration of the Agreement
            without renewal;

      (2)   The recommended travel of Executive by the Board in furtherance of
            Company business which is materially more extensive than Executive's
            travel or contemplated travel as of the effective date of this
            Agreement, taking into consideration the additional duties that will
            be assumed by Executive as of such date;

      (3)   The assignment of Executive by Company to a location more than 50
            miles from the present executive offices of Company;

      (4)   Reduction by Company in Executive's Base Salary as set forth in this
            Agreement or as the same may be increased from time to time;

      (5)   Failure by Company to continue in effect any incentive compensation
            program, policy or practice, or any savings, life insurance, health
            and accident or disability plan in which Executive is participating
            on the effective date of this Agreement (or plans which provide
            Executive with substantially similar benefits) or the taking of any
            action by Company which would adversely affect Executive's
            participation in or materially reduce his benefit under any of such
            plans or deprive him of any material fringe benefit enjoyed by him
            as of the effective date of this Agreement or any later date.
            Amendment or modification of said plans, to the extent required
            pursuant to applicable federal law and the procedures set forth in
            the respective plan, or amendments of such plans that apply to
            either all employees generally or all senior executives shall not be
            considered to be "Good Reason" for purposes of this clause (5);

      (6)   Failure of Company to obtain a specific written agreement
            satisfactory to Executive from any successor to the business, or
            substantially all the assets of Company, to assume this Agreement or
            issue a substantially similar agreement;

      (7)   The termination or attempted termination of this Agreement by
            Company purportedly for Cause if it is thereafter determined as
            provided in Section 6A(b) that Cause did not exist under this
            Agreement with respect to the termination;

      (8)   Breach of any material provisions of this Agreement by Company which
            is not cured within thirty (30) days after receipt by Company of
            written notice of such breach from Executive; or

                                       7

                                                                    CONFIDENTIAL

      (9)   Any action taken by Company over the specific, contemporaneous,
            written objection of Executive that is likely (i) to cause a
            material reduction in the value of this Agreement to Executive or
            (ii) to materially impair Executive's abilities to discharge his
            duties hereunder. This provision is not intended to affect either
            Company's or Executive's right to terminate this Agreement as
            provided for elsewhere herein.

(c)   Effect of Good Reason Termination. If Executive terminates this Agreement
      for Good Reason, as defined in Subsection 7(b), Executive shall be
      entitled to receive all of the payments and benefits provided by Section
      6B and otherwise in this Agreement to the same extent as if this Agreement
      had been terminated by Company without Cause.

8.    CHANGE IN CONTROL OF COMPANY

(a)   General. Company considers the maintenance of a sound and vital management
      to be essential to protecting and enhancing the best interests of Company,
      Parent and Parent's shareholders. Company and Parent recognize that, as is
      the case with many publicly held corporations, the continuing possibility
      of an unsolicited tender offer or other takeover bid for Parent may be
      unsettling to Executive and other senior executives of Company or Parent
      and may result in the departure or distraction of management personnel to
      the detriment of Company, Parent and Parent's shareholders. The Board and
      the Compensation Committee of the Board (the "Committee") have previously
      determined that it is in the best interests of Company, Parent and ,
      Parent's shareholders for Company to minimize these concerns by making
      this Change in Control provision an integral part of this Employment
      Agreement, which would provide Executive with a continuation of benefits
      in the event Executive's employment with Company terminates under certain
      limited circumstances.

      This provision is offered to help assure a continuing dedication by
      Executive to his duties to Company notwithstanding the occurrence of a
      tender offer or other takeover bid. In particular, the Board and the
      Committee believe it important, should Company or Parent receive proposals
      from third parties with respect to its future, to enable Executive,
      without being influenced by the uncertainties of his own situation, to
      assess and advise the Board whether such proposals would be in the best
      interests of Company, Parent and Parent's shareholders and to take such
      other action regarding such proposals as the Board might determine to be
      appropriate. The Board and the Committee also wish to demonstrate to
      Executive that Company is concerned with his welfare and intends to see he
      is treated fairly.

(b)   Continued Eligibility to Receive Benefits. In view of the foregoing and in
      further consideration of Executive's continued employment with Company, if
      a Change in Control occurs, Executive shall be entitled to a lump-sum
      severance benefit provided in Subsection 8(c) if, prior to the expiration
      of twenty-four (24) months after the Change in Control, Executive notifies
      Company of his intent to terminate his employment with Company for Good
      Reason or Company terminates Executive's employment without Cause or if,
      prior to the expiration of one hundred twenty (120) days after the Change
      in Control, Executive terminates his employment with Company. If Executive
      triggers the application of this Section by terminating employment for
      Good Reason, he must do so within one hundred twenty (120) days following
      his receipt of notice of the occurrence of the last event that constitutes
      Good Reason. The full severance benefits provided by this Section shall be
      payable regardless of the period remaining until the expiration of the
      Agreement without renewal.

(c)   Receipt of Benefits. If Executive is entitled to receive a severance
      benefit pursuant to Subsection 8(b) hereof, Company will provide Executive
      with the following benefits:

                                       8
<PAGE>
                                                                    CONFIDENTIAL

      (1)   A lump sum severance payment within ten (10) days following
            Executive's last day of work equal to the sum of (i) the greater of
            Executive's annualized Base Salary in effect on the date of
            termination of employment or Executive's highest annualized Base
            Salary in effect on any date during the term of this Agreement and
            (ii) the amount of all incentive compensation paid or accrued to
            Executive for Company's most recent four fiscal quarters then ended.

      (2)   Executive shall become fully vested in any and all stock bonus and
            stock option plans and agreements of Company and Parent in which
            Executive had an interest, vested or contingent. If applicable law
            or the terms of such plan(s) prohibit such vesting, then Company
            shall pay Executive an amount equal to the value of benefits and
            rights that would have, but for such prohibition, have been vested
            in Executive. Nothing in this Section 8(c)(2) shall prevent any
            stock option granted to Executive by Company or Parent from vesting
            upon a "change of control" as defined in and pursuant to the terms
            of the plan pursuant to which such stock option was granted.

      (3)   Executive will continue to receive life, disability, accident and
            group health and dental insurance benefits substantially similar to
            those which he was receiving immediately prior to his termination of
            employment until the earlier of (i) the end of the period of 12
            months following his termination of employment or (ii) the day on
            which he becomes eligible to receive any substantially similar
            continuing health care benefits under any plan or program of any
            other employer. The benefits provided pursuant to this Subsection
            shall be provided on substantially the same terms and conditions as
            they were provided prior to the Change in Control, except that the
            full cost of such benefits shall be paid by Company. Executive's
            right to receive continued coverage under Company's group health
            plans pursuant to Section 601 et seq. of the Employee Retirement
            Income Security Act of 1974, as it may be amended or replaced from
            time to time, shall commence following the expiration of his right
            to receive continued benefits under this Agreement. Executive's
            right to receive all forms of benefits under this Section is reduced
            to the extent he is eligible to receive any health care benefit from
            any other employer without his request to pay any premium with
            respect thereto.

      (4)   Except as otherwise provided herein, Executive shall have no duty to
            mitigate damages in order to receive the severance compensation
            described by this Subsection, and the severance compensation shall
            not be reduced or offset by other income, payments or profits
            received by Executive from any source. If Executive is entitled to
            receive the payments called for by this Subsection 8(c), Executive's
            right to receive the compensation provided by Sections 6A, 6B and 7
            shall to the extent of such payments be reduced.

(d)   Change in Control Defined. For purposes of this Agreement, a "Change in
      Control" means any one or more of the following events:

      (1)   When the individuals who, at the beginning of any period of two
            years or less, constituted the Board of Parent cease, for any
            reason, to constitute at least a majority thereof unless the
            election or nomination for election of each new director was
            approved by the vote of at least two thirds of the directors then
            still in office who were directors at the beginning of such period;

      (2)   A change of control of Parent through a transaction or series of
            transactions, such that any person (as that term is used in Sections
            13 and 14(d)(2) of the Securities Exchange

                                       9
<PAGE>
                                                                    CONFIDENTIAL

            Act of 1934 ("1934 Act")), excluding affiliates of Company as of the
            Effective Date, is or becomes the beneficial owner (as that term is
            used in Section 13(d) of the 1934 Act) directly or indirectly, of
            securities of Parent representing 50% or more of the combined voting
            power of Parent's then outstanding securities;

      (3)   Any merger, consolidation or liquidation of Parent in which Parent
            is not the continuing or surviving company or pursuant to which
            stock would be converted into cash, securities or other property,
            other than a merger of Parent in which the holders of the shares of
            stock immediately before the merger have the same proportionate
            ownership of common stock of the surviving company immediately after
            the merger;

      (4)   The shareholders of Parent approve any plan or proposal for the
            liquidation or dissolution of Parent; or

      (5)   Substantially all of the assets of Parent are sold or otherwise
            transferred to parties that are not within a "controlled group of
            corporations" (as defined in Section 1563 of the Internal Revenue
            Code of 1986, as amended (the "Code") in which Company is a member
            at the effective date of this Agreement.

(e)   Good Reason Defined. For purposes of this Section, "Good Reason" shall
      have the meaning assigned to it in Subsection 7(b).

(f)   Notice of Termination by Executive. Any termination by Executive under
      this Section 8 shall be communicated by written notice to Company which
      shall set forth generally the facts and circumstances claimed to provide a
      basis for such termination.

(g)   Gross-Up Allowance.

      (1)   General Rules. The Code places significant tax consequences on
            Executive and Company if the total payments made to Executive due,
            or deemed due, to a Change in Control exceed prescribed limits. For
            example, if Executive's "Base Period Income" (as defined below) is
            $100,000 and Executive's "Total Payments" exceed 299% of such Base
            Period Income (the "Cap"), Executive will be subject to an excise
            tax under Section 4999 of the Code of 20% of all amounts paid to him
            in excess of $100,000. In other words, if Executive's Cap is
            $299,999, he will not be subject to an excise tax if he receives
            exactly $299,999. If Executive receives $300,000, he will be subject
            to an excise tax of $40,000 (20% of $200,000). In the event that an
            excise tax is payable by Executive as a result of the application of
            Sections 280G and 4999 of the Code, for any reason, due to this
            Agreement or otherwise, Company shall pay to Executive a "gross-up
            allowance" equal in amount to the sum of (i) the excise tax
            liability of Executive on the Total Payments, and (ii) all the total
            excise, income, and payroll tax liability of Executive on the
            "gross-up allowance," further increased by all additional excise,
            income, and payroll tax liability thereon, which increase shall be
            part of the "gross-up allowance" for purpose of computing the
            "gross-up allowance." Company shall indemnify and hold Executive
            harmless from such additional tax liability for the income and
            payroll tax arising from the "gross-up allowance" and all excise tax
            arising with respect to compensation and other payments made to
            Executive under this Agreement and excise, income, and payroll tax
            on the "gross-up allowance," and all penalties and interest thereon.
            The purpose and effect of the gross-up allowance is to cause
            Executive to have the same net compensation after income, excise,
            and payroll taxes that Executive would have if there was no tax
            under Code Section 4999.

                                                                    CONFIDENTIAL

      (2)   Special Definitions. For purposes of this Section, the following
            specialized terms will have the following meanings:

            (A)   "Base Period Income". "Base Period Income" is an amount equal
                  to Executive's "annualized includable compensation" for the
                  "base period" as defined in Sections 280G(d)(1) and (2) of the
                  Internal Revenue Code of 1986, as amended (the "Code") and the
                  regulations adopted thereunder. Generally, Executive's
                  "annualized includable compensation" is the average of his
                  annual taxable income from Company for the "base period,"
                  which is the five calendar years prior to the year in which
                  the Change of Control occurs.

            (B)   "Cap" or "280G Cap". "Cap" or "280G Cap" shall mean an amount
                  equal to 2.99 times Executive's "Base Period Income." This is
                  the maximum amount which he may receive without becoming
                  subject to the excise tax imposed by Section 4999 of the Code
                  or which Company may pay without loss of deduction under
                  Section 280G of the Code.

            (C)   "Total Payments". The "Total Payments" include any "payments
                  in the nature of compensation" (as defined in Section 280G of
                  the Code and the regulations adopted thereunder), made
                  pursuant to this Agreement or otherwise, to or for Executive's
                  benefit, the receipt of which is contingent or deemed
                  contingent on a Change of Control and to which Section 280G of
                  the Code applies.

      (3)   Inclusion of Successor Sections. For purposes of this Subsection
            8(g), any reference to any Section of the Code also shall be deemed
            a reference to any Code Section resulting from the modification,
            amendment, renumbering or replacement of such Code Section.

(h)   Effect of Repeal. In the event that the provisions of Sections 280G and
      4999 of the Code are repealed without succession, Subsection 8(g) shall be
      of no further force or effect.

(i)   Employment by Successor. For purposes of this Agreement, employment by a
      successor of Company or Parent, or affiliate thereof, that has assumed
      this Agreement, shall be considered to be employment by Company or Parent
      or one of their affiliates. As a result, if Executive is employed by such
      a successor following a Change in Control, he will not be entitled to
      receive the benefits provided by Section 8(c) unless his employment with
      the successor is subsequently terminated without Cause, he terminates his
      employment for Good Reason, or he terminates his employment within 120
      days after the Change in Control in accordance with Subsection 8(b) of
      this Agreement. Nothing in this Section 8(i) shall prevent any stock
      option granted to Executive by Company or Parent from vesting upon a
      "change of control" as defined in and pursuant to the terms of the plan
      pursuant to which such stock option was granted.

9.    CONFIDENTIALITY

Executive 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 and all affiliates and subsidiaries of Company's
(collectively, "Company's Family") confidential data, including the existence,
termination and terms of this Agreement, the terms and circumstances of the
termination (by either party) of this Agreement, and information and documents
concerning Company's Family's business, customers, and 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 his possession, knowledge,
or custody concerning

                                       11
<PAGE>
                                                                    CONFIDENTIAL

the business of Company's Family, except as such disclosure may be required by
law or in connection with Executive's employment hereunder or except as such
matters may have been known to Executive at the time of his employment by
Company and except that Executive may disclose the existence, terms and
termination of this agreement to Executive's accountants, attorneys or estate
planning professionals. This covenant and agreement of Executive shall survive
this Agreement and continue to be binding upon Executive 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's
Family.

10.   RESTRICTIVE COVENANTS

(a)   Covenant Not to Compete.

      (1)   In consideration of Company's agreements contained herein and the
            payments to be made by it to Executive pursuant hereto, in the event
            of either the termination of Executive's employment by Company with
            Cause or the termination of employment by Executive without Good
            Reason, Executive agrees that, for one year ("Time Period")
            following his termination of employment and so long as Company is
            continuously not in default of its obligations to Executive
            hereunder or under any other agreement, covenant, or obligation, he
            will not, without prior written consent of Company, consult with or
            act as an advisor to another company about activity which is a
            "Competing Business" of such company in the United States, Canada or
            Europe ("Area"). For purposes of this Agreement, Executive shall be
            deemed to be engaged in a "Competing Business" if, in any capacity,
            including proprietor, partner, officer, director or employee, he
            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 any member of
            Company's Family is engaged on the date of, or any business
            contemplated by Company's business plan in effect on the date of
            notice of, Executive's termination of employment. Nothing in this
            subparagraph is intended to limit Executive's ability to own equity
            in a public company constituting less than one percent (1%) of the
            outstanding equity of such company, when Executive is not actively
            engaged in the management thereof. Company shall furnish Executive
            with a good-faith written description of the business or businesses
            in which Company's Family is then actively engaged within 30 days
            after Executive's termination of employment, and only those
            activities so timely described which are in fact actively engaged by
            Company's Family may be treated as activities of which one may be
            engaged that is competitive with Company's Family.

      (2)   The "Time Period" used for the purposes of Section 10(a)(1) shall be
            shortened to six months in the event Executive's employment is
            terminated by Company "without Cause" or by Executive for "Good
            Reason."

(b)   Non-Solicitation. Executive recognizes that Company's Family's customers
      are valuable and proprietary resources of Company's Family. Accordingly,
      Executive agrees that for a period of one year following his termination
      of employment, and only so long as Company is continuously not in default
      of its obligations to Executive hereunder or under any other agreement,
      covenant, or obligation, he will not directly or indirectly, through his
      own efforts or through the efforts of another person or entity, (i)
      solicit business from any individual or entity located in the United
      States, Canada, or Europe which obtained services from Company's Family at
      any time during Executive's employment with Company, except to the extent
      that such solicitation is non-competitive with the then actual business in
      which any member of Company's Family is engaged on the date of, or any
      business contemplated by Company's business plan in effect on the date of

      notice of, Executive's termination of employment, (ii) he will not solicit
      business from any individual or entity located in the United States,
      Canada, or Europe which was solicited by Executive on behalf of Company's
      Family, except to the extent that such solicitation is non-competitive
      with the then actual business in which any member of Company's Family is
      engaged on the date of, or any business contemplated by Company's business
      plan in effect on the date of notice of, Executive's termination of
      employment, and (iii) he will not solicit employees of Company's Family
      who would have the skills and knowledge necessary to enable or assist
      efforts by Executive to engage in a Competing Business. This covenant
      shall apply in the event of any termination of this Agreement by either
      party.

(c)   Remedies: Reasonableness. Executive acknowledges and agrees that a breach
      by Executive of the provisions of this Section 10 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 Executive from violating the
      provisions of this Section. 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
      Executive.

      Executive expressly acknowledges and agrees that (i) the Restrictive
      Covenants contained herein are reasonable as to time and geographical area
      and do not place any unreasonable burden upon him; (ii) the general public
      will not be harmed as a result of enforcement of these Restrictive
      Covenants; and (iii) Executive understands and hereby agrees to each and
      every term and condition of the Restrictive Covenants set forth in this
      Agreement.

11.   DISPUTE RESOLUTION

(a)   Mediation. Any and all disputes between the parties arising during the
      term of this Agreement, or arising at any time related to this Agreement
      or the relationship of the parties arising out of this Agreement, shall,
      if not settled by negotiation, be subject to non-binding mediation before
      an independent mediator selected by the parties pursuant to Subsection
      11(d). Notwithstanding the foregoing, both Executive and Company may seek
      preliminary injunctive or other judicial relief if such action is
      necessary to avoid irreparable damage during the pendency of the
      proceedings described in this Section 11. Any demand for mediation shall
      be made in writing and served upon the other party to the dispute
      personally, or by certified mail, return receipt requested, at the address
      specified in Section 13. The demand shall set forth with reasonable
      specificity the basis of the dispute and the relief sought. The mediation
      hearing will occur at a time and place convenient to the parties in Cook
      County, Illinois, within thirty (30) days of the date of selection or
      appointment of the mediator. Each of the parties shall bear its own costs
      of participation and representation with regard to any mediation, and each
      shall pay one-half of all charges billed by the mediator.

(b)   Arbitration. In the event that the dispute is not settled through
      mediation, the parties shall then proceed to binding arbitration before an
      independent arbitrator selected pursuant to Subsection 11(d). The mediator
      shall not serve as the arbitrator. EXCEPT AS PROVIDED IN SUBSECTION 11 (a)
      OR A CONFIRMATION PROCEEDING AS SET FORTH IN SUBSECTION 11(c), ALL
      DISPUTES INVOLVING ALLEGED UNLAWFUL EMPLOYMENT DISCRIMINATION, TERMINATION
      BY ALLEGED BREACH OF CONTRACT OR POLICY, OR ALLEGED EMPLOYMENT TORT
      COMMITTED BY COMPANY OR A REPRESENTATIVE OF COMPANY, INCLUDING CLAIMS OF
      VIOLATIONS OF FEDERAL OR STATE DISCRIMINATION STATUTES OR PUBLIC POLICY,
      SHALL BE RESOLVED PURSUANT TO THIS SECTION 11 AND THERE SHALL

      BE NO RECOURSE TO COURT, AND ALL RIGHTS OR REQUESTS FOR A JURY TRIAL ARE
      EXPRESSLY WAIVED.

      The arbitration hearing shall occur at a time and place convenient to the
      parties in Cook County, Illinois, within thirty (30) days of selection or
      appointment of the arbitrator. If Company has adopted a lawful policy that
      is applicable to arbitrations with executives, the arbitration shall be
      conducted in accordance with said policy, to the extent that the policy is
      consistent with this Agreement and the Federal Arbitration Act, 9 U.S.C.
      Sections 1-16. If no such policy has been adopted, the arbitration shall
      be governed by the National Rules for the Resolution of Employment
      Disputes of the American Arbitration Association ("AAA") in effect on the
      date of the first notice of demand for arbitration. Notwithstanding any
      provisions in such rules to the contrary, the arbitrator shall issue
      findings of fact and conclusions of law, and an award, within fifteen (15)
      days of the date of the hearing unless the parties otherwise agree.

(c)   Damages. In case of breach of contract, damages shall be limited to
      contract damages. In cases of claims based on an alleged statutory
      violation, the remedy shall be limited to the remedies provided by the
      applicable statute. In cases of employment tort, the arbitrator may award
      punitive damages if proved by clear and convincing evidence. Issues of
      procedure, arbitrability, or confirmation of award shall be governed by
      the Federal Arbitration Act, 9 U.S.C. Sections 1-16, except that court
      review of the arbitrator's award shall be that of an appellate court
      reviewing a decision of a trial judge sitting without a jury.

(d)   Selection of Mediator or Arbitrator. The parties shall select the mediator
      and arbitrator from a panel list made available by the AAA. If the parties
      are unable to agree to a mediator or an arbitrator within ten (10) days of
      receipt of a demand for mediation or arbitration, the mediator or
      arbitrator will be chosen by alternatively striking from a list of five
      (5) mediators or arbitrators obtained by Company from the AAA. Executive
      shall have the first strike.

(e)   Expenses. The prevailing party's costs and expenses of any arbitration
      (including reasonable attorneys' fees and costs) shall be awarded to such
      prevailing party to such arbitration as determined by the arbitrator.

12.   BENEFIT AND BINDING EFFECT

                              EMPLOYMENT AGREEMENT

This Employment Agreement (the "Agreement") is entered into and effective as of
April 25, 2002 between Comark, Inc., a Delaware corporation ("Company"), and
Timothy J. McGrath ("Executive").

                                 R E C I T A L S

Company is a wholly owned subsidiary of Insight Enterprises, Inc. ("Parent").
Executive is currently employed by Company in the position of Executive
Vice-President of Sales and Marketing. Company has decided to offer Executive an
employment agreement, the terms and provisions of which are set forth below.

NOW, THEREFORE, IT IS HEREBY MUTUALLY AGREED AS FOLLOWS:

1.    TERMS OF AGREEMENT

(a)   Replacement of Previous Agreements. When this Agreement becomes effective
      on April 25, 2002, it will replace all previous employment agreements
      between Executive and Company and/or its affiliates for all purposes. The
      consideration for this Agreement and the termination of such previous
      agreements is solely as stated in this Agreement and neither party shall
      have any further rights or duties under such previous agreements. The
      foregoing shall not diminish Executive's right, title and interest,
      pursuant to the terms of the Comark, Inc. Equity Incentive/Employment
      Agreement between Executive and Company dated October 13, 1999 (the
      "Equity Agreement"), to payment of his "Account" (as that term is defined
      in the Equity Agreement) as vested on April 25, 2002.

(b)   Initial Term. Executive shall be employed by Company for the duties set
      forth in Section 2 for a one-year term, commencing as of April 25, 2002
      and ending on April 25, 2003 (the "Initial Term"), unless sooner
      terminated in accordance with the provisions of this Agreement.

(c)   Renewal Term; Employment Period Defined. On each successive day after the
      commencement of the Initial Term, without further action on the part of
      Company or Executive, this Agreement shall be automatically renewed for a
      new one-year term dated effective and beginning upon each such successive
      day (the "Renewal Term"); provided, however, that Company may notify
      Executive, or Executive may notify Company, at any time, that there shall
      be no renewal of this Agreement, and in the event of such notice, neither
      party shall be under any obligation to renew or extend this Agreement. The
      period of time commencing as of the date hereof and ending on the
      effective date of the termination of employment of Executive under this or
      any successor Agreement shall be referred to as the "Employment Period."

2.    POSITION AND DUTIES

(a)   Job Duties. Company does hereby employ, engage and hire Executive to serve
      in an executive capacity, and Executive does hereby accept and agree to
      such employment, engagement, and hiring. Executive's duties and authority
      during the Employment Period shall be such executive duties as Parent's
      President (the "President") shall reasonably determine from time to time.
      Executive's initial title shall be President of Company, and his initial
      duties shall include responsibility for the day-to-day operations of
      Company and its operating subsidiaries, and for

                                        1
<PAGE>
                                                                    CONFIDENTIAL

      certain other of Parent's subsidiaries as directed by the President. Such
      title and duties may be changed from time to time by the President. In the
      absence of the President, Parent's Chief Executive Officer (the "CEO") may
      assume the President's role under this Agreement, and in the absence of
      the CEO the Parent's Board of Directors (the "Board") may assume such
      role. Executive will devote substantially all of his working time and
      effort to his duties on behalf of Company, reasonable absences because of
      illness, vacation, and personal and family exigencies excepted.

(b)   Best Efforts. Executive agrees that at all times during the Employment
      Period he will faithfully, and to the best of his ability, experience and
      talents, perform the duties that may be required of and from him and
      fulfill his responsibilities hereunder pursuant to the express terms
      hereof. Executive's ownership of, or participation (including any board
      memberships) in, any entity (other than Company ) must be disclosed to the
      Board; provided, however, that Executive need not disclose any equity
      interest held in any public company or any private company that is not
      engaged in a Competing Business as defined in Section 10 of this Agreement
      when such interest constitutes less than one percent (1.0%) of the issued
      and outstanding equity of such public or private company.

3.    COMPENSATION

(a)   Base Salary. Company shall pay Executive a "Base Salary" in consideration
      for Executive's services to Company at the rate of $300,000 per annum. 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, provided that the Base Salary shall not
      be reduced.

(b)   Incentive Compensation.

      (1)   Executive shall also be permitted to participate in such incentive
            compensation plans as are adopted by the Board or Company from time
            to time. Beginning on the date hereof and continuing through the
            Employment Period, Executive shall be entitled to an incentive
            bonus, calculated and payable quarterly, equal to one and 65/100ths
            percent (1.65%) of the combined Net Earnings (as defined below) of
            Company and Insight Services Corporation ("ISC") (collectively, the
            "Business"), provided that the Net Earnings exceed the Minimum
            Amount (as defined below) for the applicable fiscal quarter. Company
            and Executive understand and agree that Company's business shall
            include all corporate sales divisions of Company and Insight Direct
            USA, Inc. ("Insight"), and that ISC's business shall include all
            services sales divisions of Company and Insight. Furthermore,
            Company and Executive understand and agree that the Business will
            not include any small- to medium-sized business (SMB) sales
            divisions or public sector sales divisions of either Company or
            Insight, which sales divisions will be moved into other subsidiaries
            of Parent.

      (2)   For purposes of calculating Executive's incentive bonus pursuant to
            this Subsection (b), "Net Earnings" shall mean the net earnings of
            the Business calculated in accordance with accounting principles
            generally accepted in the United States (US GAAP). For the avoidance
            of doubt, Net Earnings shall be calculated after deducting (i) the
            "holding company allocation", (ii) Interest (as defined below),
            (iii) taxes and (iv) any incentive bonus amounts for Executive and
            other executives of the Business. The "holding company allocation"
            shall mean the monthly allocation of Parent's and affiliate

                                       2
<PAGE>
                                                                    CONFIDENTIAL

            companies' expenses allocated to the Business by Parent and its
            affiliate companies in a manner consistent with Parent's customary
            practices, excluding any allocation of interest income associated
            with the Purchase Debt (as defined below). "Interest" shall mean
            interest charged on external and intercompany debt, excluding
            interest charged on debt (including both external and intercompany)
            totaling approximately $150 million ("Purchase Debt") created in
            conjunction with the acquisition of Comark, Inc. by Insight
            Enterprises, Inc. The amounts payable pursuant to this Subsection
            3(b) shall be paid on or before thirty (30) days after the public
            financial reporting by Parent at the end of the applicable fiscal
            quarter. For purposes of this Subsection 3(b), the term "Minimum
            Amount" means an amount equal to eighty percent (80%) of the average
            of the Net Earnings for the immediately preceding four fiscal
            quarters ended prior to the applicable fiscal quarter.
            Notwithstanding the foregoing, the Net Earnings during the second
            calendar quarter of 2001 shall be deemed to be $4,591,000, during
            the third calendar quarter of 2001 shall be $7,641,000, during the
            fourth calendar quarter of 2001 shall be $10,655,000, during the
            first calendar quarter of 2002 shall be $4,741,000, and during the
            second calendar quarter of 2002 shall be the Net Earnings for May
            and June 2002 only (i.e., excluding April 2002) multiplied by a
            factor of 3/2. Notwithstanding any provision in this Subsection 3(b)
            to the contrary, Executive's incentive bonus for the second calendar
            quarter of 2002 shall be calculated pursuant to the foregoing
            provisions and then multiplied by a factor of 2/3, due to the fact
            that the term of this Agreement excludes most of April 2002.

      (3)   If upon final presentation of consolidated financial statements to
            Parent by Parent's outside Certified Public Accountants, the
            combined "net earnings" of the Business requires adjustment for any
            period for which the Executive received an incentive bonus
            hereunder, then, within thirty (30) days after such presentation,
            Company or Executive, as the case may be, shall pay to the other the
            amount necessary to cause the net amount of incentive bonus paid to
            be the proper amount after adjustment; provided that if Executive
            shall pay Company pursuant to the provisions of this clause (3),
            then the amount the Executive shall pay will be reduced by the taxes
            withheld by Company attributable to such amount ("Withheld
            Portion"), and the Company shall apply the Withheld Portion toward
            Company's withholding obligations with regard to any subsequent
            payments of Base Salary and incentive compensation made pursuant to
            Sections 3(a) and 3(b) or, at Company's option, Executive shall
            repay to Company any remaining amount due within seven business days
            of Company's written request therefor. Notwithstanding the
            foregoing, if the presentation of consolidated financial statements
            referenced above occurs more than five (5) years after the last day
            of the period to which the original incentive bonus at issue
            applied, no adjustments may be made pursuant to this subsection.

(c)   Incentive and Benefit Plans. Executive will be entitled to participate in
      those incentive compensation and benefit plans reserved for Company's
      executives, including any such plans offered by Parent to employees of its
      subsidiaries, including any stock option plans, in accordance with the
      terms of such compensation and benefit plans. Additionally, Executive
      shall be entitled to participate in any other benefit plans sponsored by
      Company or offered by Parent to employees of its subsidiaries, including
      any savings plan, life insurance plan and health insurance plan available
      generally to employees of Company from time to time, subject to any
      restrictions specified in, or amendments made to, such plans.

(d)   Vacation. Executive shall be entitled to four (4) weeks vacation during
      the calendar year, and such additional vacation time as the Board shall
      approve, with such vacation to be scheduled and taken in accordance with
      Company's standard vacation policies, but this provision is not intended

                                                                    CONFIDENTIAL

      to interfere with or limit Executive's discretion to determine the
      appropriate time to be devoted to his duties hereunder.

(e)   Stock Options. Concurrently herewith, Executive is being granted 100,000
      stock options under Parent's 1998 Long-Term Incentive Plan, at a strike
      price to equal the closing share price of Parent's stock on the date of
      grant and vesting at 50,000 shares on April 25, 2003 and 50,000 shares on
      April 25, 2004, such options to be evidenced by and subject to the
      provisions in the award agreements being delivered concurrently.

4.    BUSINESS EXPENSES

Company will reimburse Executive for any and all necessary, customary and usual
expenses which are incurred by Executive on behalf of Company, provided
Executive provides Company with receipts to substantiate the business expense in
accordance with Company's policies or otherwise reasonably justifies the expense
to Company.

5.    DEATH OR DISABILITY

(a)   Death. This Agreement shall terminate upon Executive's death. Executive's
      estate shall be entitled to receive the Base Salary due through the date
      of his death and any incentive compensation payable for quarters ended
      prior to Executive's death, but no Base Salary or other payment or benefit
      will be payable after death except as expressly provided elsewhere in this
      Agreement. The determination of any bonuses or incentive compensation to
      be payable for quarters ending following Executive's death will be made in
      accordance with the provisions of any incentive compensation program,
      practice, or policy in which Executive participates at the time of
      Executive's death. If there is no written incentive compensation program,
      policy, or practice in effect at the time of Executive's death, Company,
      in the exercise of its discretion, may elect to pay to Executive's estate
      a portion of the incentive compensation to which Executive would have been
      entitled (had Executive not died) for the year in which this Agreement
      terminated due to Executive's death.

(b)   Disability. The Company may terminate this Agreement upon written notice
      to Executive in the event of Executive's "Disability". For purposes of
      this Agreement, Executive shall be deemed to have a "Disability" if, for a
      minimum continuous period of six (6) months, Executive meets the
      definition of "Disability" used to determine Executive's right to benefits
      pursuant to the long-term disability insurance policy in place for
      Company's exempt employees at the end of such six-month period and such
      disability occurs due to a physical or mental injury or illness that
      occurs while Executive is actively employed by Company. Notwithstanding
      the foregoing, Executive shall be deemed to have a "Disability" if the
      sole factor preventing Executive from otherwise meeting the definition of
      "Disability" set forth above is Executive's employment and/or receipt of
      compensation pursuant to this Agreement. If this Agreement is terminated
      due to Executive's Disability, Executive shall receive the severance
      compensation called for by Section 6B(b). Company may not terminate this
      Agreement for Cause (see Section 6A) due solely to Executive's breach of
      Section 2 if such breach is the result of Executive's Disability.

6A.   TERMINATION BY COMPANY FOR CAUSE

(a)   Termination for Cause. Company may terminate this Agreement at any time
      during the Initial Term or any Renewal Terms for "Cause" upon written
      notice to Executive. If Company terminates this Agreement for "Cause,"
      Executive's Base Salary shall immediately cease, and Executive shall not
      be entitled to severance payments, incentive compensation payments or any

                                       4
<PAGE>
                                                                    CONFIDENTIAL

      other payments or benefits pursuant to this Agreement, except for any
      vested rights pursuant to any benefit plans in which Executive
      participates including Executive's stock options in Parent, any accrued
      compensation, any accrued vacation pay and similar items. For purposes of
      this Agreement, the term "Cause" shall mean the termination of Executive's
      employment by Company for one or more of the following reasons:

      (1)   The criminal conviction for any felony involving theft or
            embezzlement from Company or any affiliate;

      (2)   The criminal conviction for any felony involving moral turpitude
            that reflects adversely upon the standing of Company in the
            community;

      (3)   The criminal conviction for any felony involving fraud committed
            against Company, any affiliate or any individual or entity that
            provides goods or services to, receives goods or services from or
            otherwise deals with Company or any affiliate;

      (4)   Acts by Executive that constitute repeated and material violations
            of this Agreement, any written employment policies of Company, or
            any written directives of Company. A violation will not be
            considered to be "repeated" unless such violation has occurred more
            than once and after receipt of written notice from Company of such
            violation; or

      (5)   Failure to fully cooperate in any investigation by Company or
            Parent.

(b)   Determination of No Cause. If Company terminates Executive for Cause, and
      it is later determined at the conclusion of the Dispute Resolution process
      provided in Section 11 of this Agreement that Cause did not exist, Company
      will pay Executive the amount he would have received under this Agreement
      if his employment had been terminated by Company without Cause, plus
      interest at the Prime Rate published by the Wall Street Journal on the
      date of termination. Such payments and interest shall be calculated as of
      the effective date of the initial termination. Payment shall be made
      within fifteen (15) days after such later determination is made.

(c)   Termination by Executive without Good Reason. If Executive terminates his
      employment without Good Reason as that term is defined in Subsection 7(b),
      the consequences under this Agreement shall be identical to those of a
      termination for Cause.

(d)   Incentive Compensation. Executive shall not be entitled to receive any
      incentive compensation payments for the fiscal quarter in which his
      employment is terminated for Cause or any later quarters.

(e)   Other Plans. Except to the extent specified in this Section 6A including
      this Subsection (e), termination of Executive's employment under this
      Agreement shall not affect Executive's participation in, distributions
      from, and vested rights under any employee benefit plan of Company, which
      will be governed by the terms of those respective plans, in the event of
      Executive's termination of employment.

6B.   TERMINATION BY COMPANY WITHOUT CAUSE

(a)   Termination without Cause. Company also may terminate this Agreement at
      any time during the Initial Term or Renewal Terms without Cause. If
      Company terminates this Agreement pursuant to this Subsection, Company
      shall provide Executive with ninety (90) days advance written

                                       5
<PAGE>
                                                                    CONFIDENTIAL

      notice. This Agreement shall continue during such notice period. The
      termination of this Agreement shall be effective on the ninetieth (90th)
      day following the day on which the notice is given. Company may, at its
      discretion, place Executive on a paid administrative leave during all or
      any part of said notice period. During the administrative leave, Company
      may bar Executive's access to Company's offices or facilities if
      reasonably necessary to the smooth operation of Company, or may provide
      Executive with access subject to such reasonable terms and conditions as
      Company chooses to impose.

(b)   Severance Compensation. Should Executive's employment by Company be
      terminated without Cause, Executive shall receive as a lump sum
      immediately upon such termination the total amount of his Base Salary for
      the remainder of the Initial Term or current Renewal Term, as applicable,
      determined as if the employment of Executive had not been terminated prior
      to the end of such term and as if Executive had continued to perform all
      of his obligations under this Agreement and as an employee, officer and/or
      director of Company. Except as otherwise provided herein, Executive shall
      have no duty to mitigate damages in order to receive the severance
      compensation described by this Subsection, and the severance compensation
      shall not be reduced or offset by other income, payments or profits
      received by Executive from any source.

(c)   Incentive Compensation. If Executive is terminated without Cause,
      Executive shall receive as a lump sum immediately upon such termination
      incentive compensation for the number of quarters remaining in the Initial
      Term or latest Renewal Term, with the amount per quarter equal to the
      average bonus paid during the four quarters immediately preceding the date
      of notice of termination as if Executive had continued to perform all of
      his obligations under this Agreement and as an employee of Company. Except
      as otherwise provided herein, Executive shall have no duty to mitigate
      damages in order to receive the incentive compensation described by this
      Subsection and the incentive compensation shall not be reduced or offset
      by other income, payments or profits received by Executive from any
      source.

(d)   Other Plans. Except to the extent specified in this Section 6B including
      this Subsection (d), termination of this Agreement shall not affect
      Executive's participation in, distributions from, and vested rights under
      any employee benefit plan of Company, which will be governed by the terms
      of those respective plans, in the event of Executive's termination of
      employment. If Executive is terminated without Cause, then Executive shall
      become fully vested under any and all stock bonus and stock option plans
      and agreements in which Executive had an interest, vested or contingent.
      If applicable law or the terms of such plan(s) prohibit such vesting, then
      Company shall pay Executive an amount equal to the value of the benefits
      and rights that would have, but for such prohibition, been vested. Except
      as otherwise provided herein, Executive shall have no duty to mitigate
      damages in order to receive the compensation described by this Subsection
      and the compensation shall not be reduced or offset by other income,
      payments or profits received by Executive from any source.

(e)   Example. For example, if Company were to provide notice to Executive of
      Termination without Cause on January 1, 2003, then the Employment Period
      would end ninety days thereafter, on April 1, 2003, and Company would pay
      to Executive in a lump sum payment immediately thereafter the sum of an
      amount equal to (i) Executive's Base Salary for the next one (1) year
      totaling $300,000 (assuming the Base Salary was at that time $300,000)
      plus (ii) the incentive compensation for four fiscal quarters computed as
      stated above. Additionally, on April 1, 2003 Executive would become fully
      vested in all Company stock bonus and stock option plans and agreements in
      which Executive had an interest.

7.    TERMINATION BY EXECUTIVE

(a)   General. Executive may terminate this Agreement at any time, with or
      without "Good Reason." If Executive terminates this Agreement without Good
      Reason, Executive shall provide Company with ninety (90) days advance
      written notice. If Executive terminates this Agreement with Good Reason,
      Executive shall provide Company with thirty (30) days advance written
      notice.

(b)   Good Reason Defined. For purposes of this Agreement, "Good Reason" shall
      mean and include each of the following (unless Executive has expressly
      agreed to such event in a signed writing):

      (1)   The assignment to Executive of duties which are not executive in
            nature, except in connection with the termination of this Agreement
            for Cause, Executive's death or Disability, termination by Executive
            other than for Good Reason, or the expiration of the Agreement
            without renewal;

      (2)   The recommended travel of Executive by the Board in furtherance of
            Company business which is materially more extensive than Executive's
            travel or contemplated travel as of the effective date of this
            Agreement, taking into consideration the additional duties that will
            be assumed by Executive as of such date;

      (3)   The assignment of Executive by Company to a location more than 50
            miles from the present executive offices of Company;

      (4)   Reduction by Company in Executive's Base Salary as set forth in this
            Agreement or as the same may be increased from time to time;

      (5)   Failure by Company to continue in effect any incentive compensation
            program, policy or practice, or any savings, life insurance, health
            and accident or disability plan in which Executive is participating
            on the effective date of this Agreement (or plans which provide
            Executive with substantially similar benefits) or the taking of any
            action by Company which would adversely affect Executive's
            participation in or materially reduce his benefit under any of such
            plans or deprive him of any material fringe benefit enjoyed by him
            as of the effective date of this Agreement or any later date.
            Amendment or modification of said plans, to the extent required
            pursuant to applicable federal law and the procedures set forth in
            the respective plan, or amendments of such plans that apply to
            either all employees generally or all senior executives shall not be
            considered to be "Good Reason" for purposes of this clause (5);

      (6)   Failure of Company to obtain a specific written agreement
            satisfactory to Executive from any successor to the business, or
            substantially all the assets of Company, to assume this Agreement or
            issue a substantially similar agreement;

      (7)   The termination or attempted termination of this Agreement by
            Company purportedly for Cause if it is thereafter determined as
            provided in Section 6A(b) that Cause did not exist under this
            Agreement with respect to the termination;

      (8)   Breach of any material provisions of this Agreement by Company which
            is not cured within thirty (30) days after receipt by Company of
            written notice of such breach from Executive; or

                                       7
<PAGE>
                                                                    CONFIDENTIAL

      (9)   Any action taken by Company over the specific, contemporaneous,
            written objection of Executive that is likely (i) to cause a
            material reduction in the value of this Agreement to Executive or
            (ii) to materially impair Executive's abilities to discharge his
            duties hereunder. This provision is not intended to affect either
            Company's or Executive's right to terminate this Agreement as
            provided for elsewhere herein.

(c)   Effect of Good Reason Termination. If Executive terminates this Agreement
      for Good Reason, as defined in Subsection 7(b), Executive shall be
      entitled to receive all of the payments and benefits provided by Section
      6B and otherwise in this Agreement to the same extent as if this Agreement
      had been terminated by Company without Cause.

8.    CHANGE IN CONTROL OF COMPANY

(a)   General. Company considers the maintenance of a sound and vital management
      to be essential to protecting and enhancing the best interests of Company,
      Parent and Parent's shareholders. Company and Parent recognize that, as is
      the case with many publicly held corporations, the continuing possibility
      of an unsolicited tender offer or other takeover bid for Parent may be
      unsettling to Executive and other senior executives of Company or Parent
      and may result in the departure or distraction of management personnel to
      the detriment of Company, Parent and Parent's shareholders. The Board and
      the Compensation Committee of the Board (the "Committee") have previously
      determined that it is in the best interests of Company, Parent and ,
      Parent's shareholders for Company to minimize these concerns by making
      this Change in Control provision an integral part of this Employment
      Agreement, which would provide Executive with a continuation of benefits
      in the event Executive's employment with Company terminates under certain
      limited circumstances.

      This provision is offered to help assure a continuing dedication by
      Executive to his duties to Company notwithstanding the occurrence of a
      tender offer or other takeover bid. In particular, the Board and the
      Committee believe it important, should Company or Parent receive proposals
      from third parties with respect to its future, to enable Executive,
      without being influenced by the uncertainties of his own situation, to
      assess and advise the Board whether such proposals would be in the best
      interests of Company, Parent and Parent's shareholders and to take such
      other action regarding such proposals as the Board might determine to be
      appropriate. The Board and the Committee also wish to demonstrate to
      Executive that Company is concerned with his welfare and intends to see he
      is treated fairly.

(b)   Continued Eligibility to Receive Benefits. In view of the foregoing and in
      further consideration of Executive's continued employment with Company, if
      a Change in Control occurs, Executive shall be entitled to a lump-sum
      severance benefit provided in Subsection 8(c) if, prior to the expiration
      of twenty-four (24) months after the Change in Control, Executive notifies
      Company of his intent to terminate his employment with Company for Good
      Reason or Company terminates Executive's employment without Cause or if,
      prior to the expiration of one hundred twenty (120) days after the Change
      in Control, Executive terminates his employment with Company. If Executive
      triggers the application of this Section by terminating employment for
      Good Reason, he must do so within one hundred twenty (120) days following
      his receipt of notice of the occurrence of the last event that constitutes
      Good Reason. The full severance benefits provided by this Section shall be
      payable regardless of the period remaining until the expiration of the
      Agreement without renewal.

(c)   Receipt of Benefits. If Executive is entitled to receive a severance
      benefit pursuant to Subsection 8(b) hereof, Company will provide Executive
      with the following benefits:

                                       8
<PAGE>
                                                                    CONFIDENTIAL

      (1)   A lump sum severance payment within ten (10) days following
            Executive's last day of work equal to the sum of (i) the greater of
            Executive's annualized Base Salary in effect on the date of
            termination of employment or Executive's highest annualized Base
            Salary in effect on any date during the term of this Agreement and
            (ii) the amount of all incentive compensation paid or accrued to
            Executive for Company's most recent four fiscal quarters then ended.

      (2)   Executive shall become fully vested in any and all stock bonus and
            stock option plans and agreements of Company and Parent in which
            Executive had an interest, vested or contingent. If applicable law
            or the terms of such plan(s) prohibit such vesting, then Company
            shall pay Executive an amount equal to the value of benefits and
            rights that would have, but for such prohibition, have been vested
            in Executive. Nothing in this Section 8(c)(2) shall prevent any
            stock option granted to Executive by Company or Parent from vesting
            upon a "change of control" as defined in and pursuant to the terms
            of the plan pursuant to which such stock option was granted.

      (3)   Executive will continue to receive life, disability, accident and
            group health and dental insurance benefits substantially similar to
            those which he was receiving immediately prior to his termination of
            employment until the earlier of (i) the end of the period of 12
            months following his termination of employment or (ii) the day on
            which he becomes eligible to receive any substantially similar
            continuing health care benefits under any plan or program of any
            other employer. The benefits provided pursuant to this Subsection
            shall be provided on substantially the same terms and conditions as
            they were provided prior to the Change in Control, except that the
            full cost of such benefits shall be paid by Company. Executive's
            right to receive continued coverage under Company's group health
            plans pursuant to Section 601 et seq. of the Employee Retirement
            Income Security Act of 1974, as it may be amended or replaced from
            time to time, shall commence following the expiration of his right
            to receive continued benefits under this Agreement. Executive's
            right to receive all forms of benefits under this Section is reduced
            to the extent he is eligible to receive any health care benefit from
            any other employer without his request to pay any premium with
            respect thereto.

      (4)   Except as otherwise provided herein, Executive shall have no duty to
            mitigate damages in order to receive the severance compensation
            described by this Subsection, and the severance compensation shall
            not be reduced or offset by other income, payments or profits
            received by Executive from any source. If Executive is entitled to
            receive the payments called for by this Subsection 8(c), Executive's
            right to receive the compensation provided by Sections 6A, 6B and 7
            shall to the extent of such payments be reduced.

(d)   Change in Control Defined. For purposes of this Agreement, a "Change in
      Control" means any one or more of the following events:

      (1)   When the individuals who, at the beginning of any period of two
            years or less, constituted the Board of Parent cease, for any
            reason, to constitute at least a majority thereof unless the
            election or nomination for election of each new director was
            approved by the vote of at least two thirds of the directors then
            still in office who were directors at the beginning of such period;

      (2)   A change of control of Parent through a transaction or series of
            transactions, such that any person (as that term is used in Sections
            13 and 14(d)(2) of the Securities Exchange

                                       9
<PAGE>
                                                                    CONFIDENTIAL

            Act of 1934 ("1934 Act")), excluding affiliates of Company as of the
            Effective Date, is or becomes the beneficial owner (as that term is
            used in Section 13(d) of the 1934 Act) directly or indirectly, of
            securities of Parent representing 50% or more of the combined voting
            power of Parent's then outstanding securities;

      (3)   Any merger, consolidation or liquidation of Parent in which Parent
            is not the continuing or surviving company or pursuant to which
            stock would be converted into cash, securities or other property,
            other than a merger of Parent in which the holders of the shares of
            stock immediately before the merger have the same proportionate
            ownership of common stock of the surviving company immediately after
            the merger;

      (4)   The shareholders of Parent approve any plan or proposal for the
            liquidation or dissolution of Parent; or

      (5)   Substantially all of the assets of Parent are sold or otherwise
            transferred to parties that are not within a "controlled group of
            corporations" (as defined in Section 1563 of the Internal Revenue
            Code of 1986, as amended (the "Code") in which Company is a member
            at the effective date of this Agreement.

(e)   Good Reason Defined. For purposes of this Section, "Good Reason" shall
      have the meaning assigned to it in Subsection 7(b).

(f)   Notice of Termination by Executive. Any termination by Executive under
      this Section 8 shall be communicated by written notice to Company which
      shall set forth generally the facts and circumstances claimed to provide a
      basis for such termination.

(g)   Gross-Up Allowance.

      (1)   General Rules. The Code places significant tax consequences on
            Executive and Company if the total payments made to Executive due,
            or deemed due, to a Change in Control exceed prescribed limits. For
            example, if Executive's "Base Period Income" (as defined below) is
            $100,000 and Executive's "Total Payments" exceed 299% of such Base
            Period Income (the "Cap"), Executive will be subject to an excise
            tax under Section 4999 of the Code of 20% of all amounts paid to him
            in excess of $100,000. In other words, if Executive's Cap is
            $299,999, he will not be subject to an excise tax if he receives
            exactly $299,999. If Executive receives $300,000, he will be subject
            to an excise tax of $40,000 (20% of $200,000). In the event that an
            excise tax is payable by Executive as a result of the application of
            Sections 280G and 4999 of the Code, for any reason, due to this
            Agreement or otherwise, Company shall pay to Executive a "gross-up
            allowance" equal in amount to the sum of (i) the excise tax
            liability of Executive on the Total Payments, and (ii) all the total
            excise, income, and payroll tax liability of Executive on the
            "gross-up allowance," further increased by all additional excise,
            income, and payroll tax liability thereon, which increase shall be
            part of the "gross-up allowance" for purpose of computing the
            "gross-up allowance." Company shall indemnify and hold Executive
            harmless from such additional tax liability for the income and
            payroll tax arising from the "gross-up allowance" and all excise tax
            arising with respect to compensation and other payments made to
            Executive under this Agreement and excise, income, and payroll tax
            on the "gross-up allowance," and all penalties and interest thereon.
            The purpose and effect of the gross-up allowance is to cause
            Executive to have the same net compensation after income, excise,
            and payroll taxes that Executive would have if there was no tax
            under Code Section 4999.

                                                                    CONFIDENTIAL

      (2)   Special Definitions. For purposes of this Section, the following
            specialized terms will have the following meanings:

            (A)   "Base Period Income". "Base Period Income" is an amount equal
                  to Executive's "annualized includable compensation" for the
                  "base period" as defined in Sections 280G(d)(1) and (2) of the
                  Internal Revenue Code of 1986, as amended (the "Code") and the
                  regulations adopted thereunder. Generally, Executive's
                  "annualized includable compensation" is the average of his
                  annual taxable income from Company for the "base period,"
                  which is the five calendar years prior to the year in which
                  the Change of Control occurs.

            (B)   "Cap" or "280G Cap". "Cap" or "280G Cap" shall mean an amount
                  equal to 2.99 times Executive's "Base Period Income." This is
                  the maximum amount which he may receive without becoming
                  subject to the excise tax imposed by Section 4999 of the Code
                  or which Company may pay without loss of deduction under
                  Section 280G of the Code.

            (C)   "Total Payments". The "Total Payments" include any "payments
                  in the nature of compensation" (as defined in Section 280G of
                  the Code and the regulations adopted thereunder), made
                  pursuant to this Agreement or otherwise, to or for Executive's
                  benefit, the receipt of which is contingent or deemed
                  contingent on a Change of Control and to which Section 280G of
                  the Code applies.

      (3)   Inclusion of Successor Sections. For purposes of this Subsection
            8(g), any reference to any Section of the Code also shall be deemed
            a reference to any Code Section resulting from the modification,
            amendment, renumbering or replacement of such Code Section.

(h)   Effect of Repeal. In the event that the provisions of Sections 280G and
      4999 of the Code are repealed without succession, Subsection 8(g) shall be
      of no further force or effect.

(i)   Employment by Successor. For purposes of this Agreement, employment by a
      successor of Company or Parent, or affiliate thereof, that has assumed
      this Agreement, shall be considered to be employment by Company or Parent
      or one of their affiliates. As a result, if Executive is employed by such
      a successor following a Change in Control, he will not be entitled to
      receive the benefits provided by Section 8(c) unless his employment with
      the successor is subsequently terminated without Cause, he terminates his
      employment for Good Reason, or he terminates his employment within 120
      days after the Change in Control in accordance with Subsection 8(b) of
      this Agreement. Nothing in this Section 8(i) shall prevent any stock
      option granted to Executive by Company or Parent from vesting upon a
      "change of control" as defined in and pursuant to the terms of the plan
      pursuant to which such stock option was granted.

9.    CONFIDENTIALITY

Executive 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 and all affiliates and subsidiaries of Company's
(collectively, "Company's Family") confidential data, including the existence,
termination and terms of this Agreement, the terms and circumstances of the
termination (by either party) of this Agreement, and information and documents
concerning Company's Family's business, customers, and 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 his possession, knowledge,
or custody concerning

                                       11
<PAGE>
                                                                    CONFIDENTIAL

the business of Company's Family, except as such disclosure may be required by
law or in connection with Executive's employment hereunder or except as such
matters may have been known to Executive at the time of his employment by
Company and except that Executive may disclose the existence, terms and
termination of this agreement to Executive's accountants, attorneys or estate
planning professionals. This covenant and agreement of Executive shall survive
this Agreement and continue to be binding upon Executive 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's
Family.

10.   RESTRICTIVE COVENANTS

(a)   Covenant Not to Compete.

      (1)   In consideration of Company's agreements contained herein and the
            payments to be made by it to Executive pursuant hereto, in the event
            of either the termination of Executive's employment by Company with
            Cause or the termination of employment by Executive without Good
            Reason, Executive agrees that, for one year ("Time Period")
            following his termination of employment and so long as Company is
            continuously not in default of its obligations to Executive
            hereunder or under any other agreement, covenant, or obligation, he
            will not, without prior written consent of Company, consult with or
            act as an advisor to another company about activity which is a
            "Competing Business" of such company in the United States, Canada or
            Europe ("Area"). For purposes of this Agreement, Executive shall be
            deemed to be engaged in a "Competing Business" if, in any capacity,
            including proprietor, partner, officer, director or employee, he
            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 any member of
            Company's Family is engaged on the date of, or any business
            contemplated by Company's business plan in effect on the date of
            notice of, Executive's termination of employment. Nothing in this
            subparagraph is intended to limit Executive's ability to own equity
            in a public company constituting less than one percent (1%) of the
            outstanding equity of such company, when Executive is not actively
            engaged in the management thereof. Company shall furnish Executive
            with a good-faith written description of the business or businesses
            in which Company's Family is then actively engaged within 30 days
            after Executive's termination of employment, and only those
            activities so timely described which are in fact actively engaged by
            Company's Family may be treated as activities of which one may be
            engaged that is competitive with Company's Family.

      (2)   The "Time Period" used for the purposes of Section 10(a)(1) shall be
            shortened to six months in the event Executive's employment is
            terminated by Company "without Cause" or by Executive for "Good
            Reason."

(b)   Non-Solicitation. Executive recognizes that Company's Family's customers
      are valuable and proprietary resources of Company's Family. Accordingly,
      Executive agrees that for a period of one year following his termination
      of employment, and only so long as Company is continuously not in default
      of its obligations to Executive hereunder or under any other agreement,
      covenant, or obligation, he will not directly or indirectly, through his
      own efforts or through the efforts of another person or entity, (i)
      solicit business from any individual or entity located in the United
      States, Canada, or Europe which obtained services from Company's Family at
      any time during Executive's employment with Company, except to the extent
      that such solicitation is non-competitive with the then actual business in
      which any member of Company's Family is engaged on the date of, or any
      business contemplated by Company's business plan in effect on the date of

                                       12
<PAGE>
                                                                    CONFIDENTIAL

      notice of, Executive's termination of employment, (ii) he will not solicit
      business from any individual or entity located in the United States,
      Canada, or Europe which was solicited by Executive on behalf of Company's
      Family, except to the extent that such solicitation is non-competitive
      with the then actual business in which any member of Company's Family is
      engaged on the date of, or any business contemplated by Company's business
      plan in effect on the date of notice of, Executive's termination of
      employment, and (iii) he will not solicit employees of Company's Family
      who would have the skills and knowledge necessary to enable or assist
      efforts by Executive to engage in a Competing Business. This covenant
      shall apply in the event of any termination of this Agreement by either
      party.

(c)   Remedies: Reasonableness. Executive acknowledges and agrees that a breach
      by Executive of the provisions of this Section 10 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 Executive from violating the
      provisions of this Section. 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
      Executive.

      Executive expressly acknowledges and agrees that (i) the Restrictive
      Covenants contained herein are reasonable as to time and geographical area
      and do not place any unreasonable burden upon him; (ii) the general public
      will not be harmed as a result of enforcement of these Restrictive
      Covenants; and (iii) Executive understands and hereby agrees to each and
      every term and condition of the Restrictive Covenants set forth in this
      Agreement.

11.   DISPUTE RESOLUTION

(a)   Mediation. Any and all disputes between the parties arising during the
      term of this Agreement, or arising at any time related to this Agreement
      or the relationship of the parties arising out of this Agreement, shall,
      if not settled by negotiation, be subject to non-binding mediation before
      an independent mediator selected by the parties pursuant to Subsection
      11(d). Notwithstanding the foregoing, both Executive and Company may seek
      preliminary injunctive or other judicial relief if such action is
      necessary to avoid irreparable damage during the pendency of the
      proceedings described in this Section 11. Any demand for mediation shall
      be made in writing and served upon the other party to the dispute
      personally, or by certified mail, return receipt requested, at the address
      specified in Section 13. The demand shall set forth with reasonable
      specificity the basis of the dispute and the relief sought. The mediation
      hearing will occur at a time and place convenient to the parties in Cook
      County, Illinois, within thirty (30) days of the date of selection or
      appointment of the mediator. Each of the parties shall bear its own costs
      of participation and representation with regard to any mediation, and each
      shall pay one-half of all charges billed by the mediator.

(b)   Arbitration. In the event that the dispute is not settled through
      mediation, the parties shall then proceed to binding arbitration before an
      independent arbitrator selected pursuant to Subsection 11(d). The mediator
      shall not serve as the arbitrator. EXCEPT AS PROVIDED IN SUBSECTION 11 (a)
      OR A CONFIRMATION PROCEEDING AS SET FORTH IN SUBSECTION 11(c), ALL
      DISPUTES INVOLVING ALLEGED UNLAWFUL EMPLOYMENT DISCRIMINATION, TERMINATION
      BY ALLEGED BREACH OF CONTRACT OR POLICY, OR ALLEGED EMPLOYMENT TORT
      COMMITTED BY COMPANY OR A REPRESENTATIVE OF COMPANY, INCLUDING CLAIMS OF
      VIOLATIONS OF FEDERAL OR STATE DISCRIMINATION STATUTES OR PUBLIC POLICY,
      SHALL BE RESOLVED PURSUANT TO THIS SECTION 11 AND THERE SHALL

<PAGE>
                                                                    CONFIDENTIAL

      BE NO RECOURSE TO COURT, AND ALL RIGHTS OR REQUESTS FOR A JURY TRIAL ARE
      EXPRESSLY WAIVED.

      The arbitration hearing shall occur at a time and place convenient to the
      parties in Cook County, Illinois, within thirty (30) days of selection or
      appointment of the arbitrator. If Company has adopted a lawful policy that
      is applicable to arbitrations with executives, the arbitration shall be
      conducted in accordance with said policy, to the extent that the policy is
      consistent with this Agreement and the Federal Arbitration Act, 9 U.S.C.
      Sections 1-16. If no such policy has been adopted, the arbitration shall
      be governed by the National Rules for the Resolution of Employment
      Disputes of the American Arbitration Association ("AAA") in effect on the
      date of the first notice of demand for arbitration. Notwithstanding any
      provisions in such rules to the contrary, the arbitrator shall issue
      findings of fact and conclusions of law, and an award, within fifteen (15)
      days of the date of the hearing unless the parties otherwise agree.

(c)   Damages. In case of breach of contract, damages shall be limited to
      contract damages. In cases of claims based on an alleged statutory
      violation, the remedy shall be limited to the remedies provided by the
      applicable statute. In cases of employment tort, the arbitrator may award
      punitive damages if proved by clear and convincing evidence. Issues of
      procedure, arbitrability, or confirmation of award shall be governed by
      the Federal Arbitration Act, 9 U.S.C. Sections 1-16, except that court
      review of the arbitrator's award shall be that of an appellate court
      reviewing a decision of a trial judge sitting without a jury.

(d)   Selection of Mediator or Arbitrator. The parties shall select the mediator
      and arbitrator from a panel list made available by the AAA. If the parties
      are unable to agree to a mediator or an arbitrator within ten (10) days of
      receipt of a demand for mediation or arbitration, the mediator or
      arbitrator will be chosen by alternatively striking from a list of five
      (5) mediators or arbitrators obtained by Company from the AAA. Executive
      shall have the first strike.

(e)   Expenses. The prevailing party's costs and expenses of any arbitration
      (including reasonable attorneys' fees and costs) shall be awarded to such
      prevailing party to such arbitration as determined by the arbitrator.

12.   BENEFIT AND BINDING EFFECT
