      NOW, THEREFORE, in consideration of the mutual promises and covenants set
forth herein, the receipt and sufficiency of which are hereby acknowledged, the
parties hereto, intending to be legally bound, agree as follows:

      Section 1. Non-Competition; Non-Solicitation. In view of the fact that any
activity of the Stockholder in violation of the terms hereof would adversely
affect the Company and any subsidiaries and would deprive the Investors under
the Purchase Agreement and the Note Purchase Agreement of the benefits of their
bargains thereunder, and to preserve the goodwill associated with the Company's
business, the Stockholder hereby agrees to the following restrictions on his
activities:

            (a)   Non-Competition and Non-Solicitation. The Stockholder hereby
agrees that during the period commencing on the date hereof and ending on the
date which is the later of five (5) years after the date hereof, it will not,
without the express written consent of the Company, directly or indirectly,
anywhere in the United States or in any foreign country where the Company has
conducted business, is conducting business or is presently contemplating
conducting business, (a) engage in any activity which is or (b) participate or
invest in, provide or facilitate the provision of financing to, or assist
(whether as owner, part-owner, shareholder, member, partner, director, officer,
trustee, employee, agent or consultant, or in any other capacity) any business,
organization or person other than the Company (or any subsidiary of the
Company), including any such business, organization or person involving, or
which is, a family member of the Stockholder, whose business, activities,
products or services are competitive with any of the business, activities,
products or services conducted or offered by the Company or any of its
subsidiaries, which business, activities, products and services shall include in
any event and without limitation the Company Business. Without implied
limitation, the forgoing covenant shall be deemed to prohibit (a) hiring or
engaging or attempting to hire or engage for or on behalf of the Stockholder or
any such competitor any officer or employee of the Company or any of its
subsidiaries, or any former employee of the Company and any of its subsidiaries
who was employed during the six (6) month period immediately preceding the date
hereof, (b) encouraging for or on behalf of the Stockholder or any such
competitor any such officer or employee to terminate its relationship or
employment with the Company or any of its subsidiaries, (c) soliciting for or on
behalf of the Stockholder or any such competitor any client of the Company or
any of its subsidiaries and (d) diverting to any person any client or business
opportunity of the Company or any of any of its subsidiaries.

      Notwithstanding anything herein to the contrary, the Stockholder may make
passive investments in any publicly traded enterprise if such investment
constitutes less than one percent (2%) of the equity of such enterprise.

      Neither the Stockholder nor any business entity controlled by the
Stockholder is a party to any contract, commitment, arrangement or agreement
which could, following the date hereof, restrain or restrict the Company or any
subsidiary of the Company from carrying on its business or restrain or restrict
the Stockholder from performing the Stockholder's employment obligations, and,
as of the date of this Agreement, the Stockholder has no business interests
whatsoever in or relating to the industries in which the Company and its
subsidiaries currently engage other than the Stockholder's interest in the
Company and other than interests in public companies of less than one percent
(2%).

                                        2

<PAGE>

      For purposes of this Agreement, any reference to a (i) "subsidiary" or
"subsidiaries" of the Company shall be deemed to include any entities directly
or indirectly controlled by it through an ownership of more than fifty percent
(50%) of the voting interests and (ii) the term "person" shall mean an
individual, a corporation, an association, a partnership, a limited liability
company, an estate, a trust, and any other entity or organization.

      Section 2. Scope of Agreement. The parties acknowledge that the time,
scope, geographic area and other provisions of this Agreement have been
specifically negotiated by sophisticated commercial parties, and they agree that
(a) all such provisions are reasonable under the circumstances of the
transactions contemplated hereby, (b) are given as an integral and essential
part of the transactions contemplated hereby and (c) but for the covenants of
the Stockholder contained in this Agreement, the Company and the Investors would
not have entered into or consummated the transactions contemplated hereby. The
Stockholder has independently consulted with his counsel and has been advised in
all respects concerning the reasonableness and propriety of the covenants
contained herein, with specific regard to the business to be conducted by
Company and its subsidiaries, and represents that the Agreement is intended to
be, and shall be, fully enforceable and effective in accordance with its terms.

      Section 3. Confidentiality. The Stockholder agrees that all information,
whether or not in writing, concerning the Company Business or the Company's
technology, business relationships or financial affairs which the Company has
not released to the general public (collectively, "Proprietary Information") is
and will be the exclusive property of the Company. By way of illustration,
Proprietary Information may include information or material which has not been
made generally available to the public, such as: (a) corporate information,
including plans, strategies, methods, policies, resolutions, negotiations or
litigation; (b) marketing information, including strategies, methods, customer
identities or other information about customers, prospect identities or other
information about prospects, or market analyses or projections; (c) financial
information, including cost and performance data, debt arrangements, equity
structure, investors and holdings, purchasing and sales data and price lists;
and (d) operational and technological information, including plans,
specifications, manuals, forms, templates, software, designs, procedures,
formulas, discoveries, inventions, improvements, concepts and ideas; and (e)
personnel information, including personnel lists, reporting or organizational
structure, resumes, personnel data, compensation structure, performance
evaluations and termination arrangements or documents. Proprietary Information
also includes information received in confidence by the Company from its
customers or suppliers or other third parties. The Stockholder hereby agrees
that it will not, at any time, without the Company's prior written permission,
disclose any Proprietary Information to anyone outside of the Company, or use or
permit to be used any Proprietary Information for any purpose other than the
performance of my duties as an employee of the Company, if applicable. The
Stockholder hereby agrees to cooperate with the Company and use is best efforts
to prevent the unauthorized disclosure of all Proprietary Information.

      Section 4. Certain Remedies; Severability. It is specifically understood
and agreed that any breach of the provisions of this Agreement by the
Stockholder or any of his affiliates will result in irreparable injury to the
Company and its subsidiaries, that the remedy at law alone will be an inadequate
remedy for such breach and that, in addition to any other remedy it may have,
the Company and, upon authorization by the Board of Directors of the Company,
its subsidiaries shall be entitled to enforce the specific performance of this
Agreement by the Stockholder

                                        3

<PAGE>

through both temporary and permanent injunctive relief without the necessity of
proving actual damages, but without limitation of their right to damages and any
and all other remedies available to them, it being understood that injunctive
relief is in addition to, and not in lieu of, such other remedies. In the event
that any covenant contained in this Agreement shall be determined by any court
of competent jurisdiction to be unenforceable by reason of its extending for too
great a period of time or over too great a geographical area or by reason of its
being too extensive in any other respect, it shall be interpreted to extend only
over the maximum period of time for which it may be enforceable and/or over the
maximum geographical area as to which it may be enforceable and/or to the
maximum extent in all other respects as to which it may be enforceable, all as
determined by such court in such action. The existence of any claim or cause of
action which the Stockholder may have against the Company or any of its
subsidiaries shall not constitute a defense or bar to the enforcement of any of
the provisions of this Agreement.

      Section 5. Jurisdiction. The parties hereby irrevocably submit to the
non-exclusive jurisdiction of the courts of the State of Illinois to construe
and enforce the covenants contained in this Agreement. In the event that the
courts of any state shall hold such covenants unenforceable (in whole or in
part) by reason of the breadth of such scope or otherwise, it is the intention
of the parties hereto that such determination shall not bar or in any way affect
the right of the Company or, upon authorization by the Board of Directors of the
Company, any of its subsidiaries to the relief provided for herein in the courts
of any other state within the geographic scope of such covenants, as to breaches
of such covenants in such other respective states, the above covenants as they
relate to each state being, for this purpose, severable into diverse and
independent covenants.

      Section 6. Notices. Any notice or demand which is required or provided to
be given under this Agreement shall be deemed to have been sufficiently given
and received for all purposes when delivered by hand, telecopy, telex or other
method of facsimile, or five days after being sent by certified or registered
mail, postage and charges prepaid, return receipt requested, or two days after
being sent by overnight delivery providing receipt of delivery, to the following

the enforcement at any time of any other right hereunder or be deemed a waiver
of any subsequent breach of the provision so breached, or of any other breach
hereunder. This Agreement shall inure to the benefit of, and be binding upon,

            (d)   Compliance with the provisions of this Section 5 shall in no
way create or be deemed to create any obligation, express or implied, on the
part of the Company or any of its affiliates with respect to the continuation of
any particular benefit or other plan or arrangement maintained by them or their
subsidiaries as of or prior to the date hereof or the creation and maintenance
of any particular benefit or other plan or arrangement at any time after the
date hereof, except as contemplated by Section 5(b) and 5(c).

      6.    Termination and Termination Benefits. Notwithstanding the provisions
of Section 2, Employee's employment under this Agreement shall terminate under
the following circumstances set forth in this Section 6.

            (a)   Termination by the Company for Cause. Employee's employment
under this Agreement may be terminated for cause without further liability on
the part of the Company effective immediately upon a vote of the Board of
Directors and written notice to Employee. Only the following shall constitute
"cause" for such termination:

                  (i)   dishonest statements or acts of Employee with respect to
            the Company or any affiliate of the Company;

                  (ii)  the commission by Employee of, or indictment of Employee
            for, (A) a felony or (B) any misdemeanor involving moral turpitude,
            deceit, dishonesty or fraud ("indictment," for these purposes,
            meaning an indictment, probable cause hearing or any other procedure
            pursuant to which an initial determination of probable or reasonable
            cause with respect to such offense is made);

                  (iii) the commission, in the reasonable judgment of the Board
            of Directors, of an act involving a material violation of procedures
            or policies of the Company;

                  (iv)  a material and sustained failure of Employee to perform
            the duties and responsibilities assigned or delegated under this
            Agreement, as determined by the Board of the Directors, which such
            failure continues for an unreasonable period of time, as determined
            by the Board of Directors, after written notice has been given to
            the Employee by the Board of Directors;

                  (v)   gross negligence, willful misconduct or insubordination
            of Employee with respect to the Company or any affiliate of the
            Company; or

                  (vi)  breach by Employee of any of Employee's obligations
            under this Agreement.

            (b)   Termination by Employee Other than for Good Reason. Employee's
employment under this Agreement may be terminated by Employee by written notice
to the Board of Directors at least sixty (60) days prior to such termination.

            (c)   Termination by Employee for Good Reason. Subject to the
payment of Termination Benefits pursuant to Section 6(e) below, Employee's
employment under this Agreement also may be terminated by Employee for Good
Reason (as defined below) (which termination must be within ninety (90) days of
the occurrence of the events giving rise to such Good Reason) by written notice
to the Board of Directors

                                        3

<PAGE>

setting forth such Good Reason and giving the Company a reasonable period of
time, not less than ten (10) business days, to eliminate such Good Reason. For
purposes of this Agreement, "Good Reason" shall mean the occurrence of any of
the following events: (i) a substantial adverse change in the nature or scope of
the Employee's responsibilities, authorities, powers, functions or duties under
this Agreement; (ii) a reduction in the Employee's annual base salary except for
an across-the-board salary reduction similarly affecting all or substantially
all management employees; or (iii) the relocation of the offices at which the
Employee is principally employed to a location more than seventy (75) miles from
such offices.

            (d)   Termination by the Company Without Cause. Subject to the
payment of Termination Benefits pursuant to Section 6(e), Employee's employment
under this Agreement may be terminated without cause by the Company by a vote of
the Board of Directors upon written notice to Employee. It is expressly agreed
and understood that if this Agreement is terminated by the Company without cause
as provided in this Section 6(d), it shall not impair or otherwise affect
Employee's Continuing Obligations (as defined below).

            (e)   Certain Termination Benefits. Unless otherwise specifically
provided in this Agreement or otherwise required by law, all compensation and
benefits payable to Employee under this Agreement shall terminate on the date of
termination of Employee's employment under this Agreement. Notwithstanding the
foregoing, in the event of termination of Employee's employment with the Company
pursuant to Section 6(c) or Section 6(d) above, the Company shall provide to
Employee the following termination benefits ("Termination Benefits"):

            (i)   continuation of salary at a rate equal to 100% of Employee's
      Base Salary as in effect on the date of termination for a period of three
      (3) years from the date of termination (payment shall be subject to
      withholding under applicable law and shall be made in periodic
      installments in accordance with the Company's usual practice for executive
      officers of the Company as in effect from time to time); and

            (ii)  continuation of group health plan benefits during the time in
      which Employee is receiving payments pursuant to subsection (i) above, to
      the extent authorized by and consistent with 29 U.S.C. Section 1161 et
      seq. (commonly known as "COBRA"), with the cost of the regular premium for
      such benefits shared in the same relative proportion by the Company and
      Employee as in effect on the date of termination.

The Company shall have the right to terminate all of Termination Benefits set
forth in (i) and (ii) in the event that Employee fails to comply with Employee's
Continuing Obligations under this Agreement. The Company's liability for Base
Salary continuation pursuant to Section 6(e)(i) shall be reduced by the amount
of any severance pay due or otherwise paid to Employee pursuant to any severance
pay plan or stay bonus plan of the

                                        4

<PAGE>

Company. Notwithstanding the foregoing, nothing in this Section 6(e) shall be
construed to affect Employee's right to receive COBRA continuation entirely at
Employee's own cost to the extent that Employee may continue to be entitled to
COBRA continuation after Employee's right to cost sharing under Section 6(e)(ii)
ceases. The Company and Employee agree that the Termination Benefits paid by the
Company to Employee under this Section 6(e) shall be in full satisfaction,
compromise and release of any claims arising out of any termination of
Employee's employment pursuant to Section 6(d), and that the payment of the
Termination Benefits shall be contingent upon Employee's delivery of a general
release of any and all claims (other than those arising under this Agreement)
upon termination of employment in a form reasonably satisfactory to the Company,
it being understood that no Termination Benefits shall be provided unless and
until Employee executes and delivers such release.

            (f)   Disability. If Employee shall be disabled so as to be unable
to perform the essential functions of Employee's then existing position or
positions under this Agreement with or without reasonable accommodation, the
Board of Directors may remove Employee from any responsibilities and/or reassign
Employee to another position with the Company for the remainder of the Term or
during the period of such disability. Notwithstanding any such removal or
reassignment, Employee shall continue to receive Employee's full Base Salary
(less any disability pay or sick pay benefits to which Employee may be entitled
under the Company's policies) and benefits under Section 4 of this Agreement
(except to the extent that Employee may be ineligible for one or more such
benefits under applicable plan terms) for a period of time equal to the lesser
of (i) six (6) months; or (ii) the remainder of the Term. If any question shall
arise as to whether during any period Employee is disabled so as to be unable to
perform the essential functions of Employee's then existing position or
positions with or without reasonable accommodation, Employee may, and at the
request of the Company shall, submit to the Company a certification in
reasonable detail by a physician selected by the Company to whom Employee or
Employee's guardian has no reasonable objection as to whether Employee is so
disabled or how long such disability is expected to continue, and such
certification shall for the purposes of this Agreement be conclusive of the
issue. Employee shall cooperate with any reasonable request of the physician in
connection with such certification. If such question shall arise and Employee
shall fail to submit such certification, the Company's determination of such
issue shall be binding on Employee. Nothing in this Section 6(e) shall be
construed to waive Employee's rights, if any, under existing law including,
without limitation, the Family and Medical Leave Act of 1993, 29 U.S.C. Section
2601 et seq. and the Americans with Disabilities Act, 42 U.S.C. Section 12101 et
seq.

            (g)   Death. Employee's employment and all obligations of the
Company hereunder shall terminate in the event of the death of the Employee
other than any obligation to pay earned but unpaid Base Salary.

            (h)   Notwithstanding termination of this Agreement as provided in
this Section 6 or any other termination of Employee's employment with the
Company, Employee's obligations under Section 7 hereof (the "Continuing
Obligations") shall

                                        5

<PAGE>

survive any termination of Employee's employment with the Company at any time
and for any reason.

      7.    Non-Competition; Non-Solicitation; Confidentiality; Proprietary
Rights.

            (a)   The Employee hereby agrees that during the period commencing
on the date hereof and ending on the date that is five years following the date
of the termination of Employee's employment with the Company (the
"Noncompetition Period"), the Employee will not, without the express written
consent of the Company, directly or indirectly, anywhere in the United States or
in any foreign country in which the Company has conducted business, is
conducting business or is presently contemplating conducting business, engage in
any activity which is, or participate or invest in, or provide or facilitate the
provision of financing to, or assist (whether as owner, part-owner, shareholder,
member, partner, director, officer, trustee, employee, agent or consultant, or
in any other capacity), any business, organization or person other than the
Company (or any subsidiary or affiliate of the Company), and including any such
business, organization or person involving, or which is, a family member of the
Employee, whose business, activities, products or services are competitive with
any of the business, activities, products or services conducted or offered by
the Company or its subsidiaries or affiliates during any period in which the
Employee serves as an officer or employee of the Company or any of its
subsidiaries or affiliates. Without implied limitation, the foregoing covenant
shall be deemed to prohibit (a) hiring or engaging or attempting to hire or
engage for or on behalf of the Employee or any such competitor any officer or
employee of the Company or any of its direct and/or indirect subsidiaries and
affiliates, or any former employee of the Company and any of its direct and/or
indirect subsidiaries and affiliates who was employed during the six (6) month
period immediately preceding the date of such attempt to hire or engage, (b)
encouraging for or on behalf of the Employee or any such competitor any such
officer or employee to terminate his or her relationship or employment with the
Company or any of its direct or indirect subsidiaries and affiliates, (c)
soliciting for or on behalf of Employee or any such competitor any client of the
Company or any of its direct or indirect subsidiaries and affiliates, or any
former client of the Company or any of its direct or indirect subsidiaries and
affiliates who was a client during the six (6) month period immediately
preceding the date of such solicitation and (d) diverting to any person (as
hereinafter defined) any client or business opportunity of the Company or any of
any of its direct or indirect subsidiaries and affiliates.

            Notwithstanding anything herein to the contrary, the Employee may
make passive investments in any enterprise the shares of which are publicly
traded if such investment constitutes less than two percent (2%) of the equity
of such enterprise.

            Neither the Employee nor any business entity controlled by the
Employee is a party to any contract, commitment, arrangement or agreement which
could, following the date hereof, restrain or restrict the Company or any
subsidiary or affiliate of the Company from carrying on its business or restrain
or restrict the Employee from performing his employment obligations, and as of
the date of this Agreement the

                                        6

<PAGE>

Employee has no business interests whatsoever in or relating to the industries
in which the Company or its subsidiaries or affiliates currently engage, and
other than passive investments in the shares of public companies of less than
two percent (2%).

            (b)   In the course of performing services hereunder, on behalf of
the Company (for purposes of this Section 7 including all predecessors of the
Company) and its affiliates, Employee has had and from time to time will have
access to Confidential Information (as defined below). Employee agrees (a) to
hold the Confidential Information in strict confidence, (b) not to disclose the
Confidential Information to any person (other than in the regular business of
the Company or its affiliates), and (c) not to use, directly or indirectly, any
of the Confidential Information for any purpose other than on behalf of the
Company and its affiliates. All documents, records, data, apparatus, equipment
and other physical property, whether or not pertaining to Confidential
Information, that are furnished to Employee by the Company or are produced by
Employee in connection with Employee's employment will be and remain the sole
property of the Company. Upon the termination of Employee's employment with the
Company for any reason and as and when otherwise requested by the Company, all
Confidential Information (including, without limitation, all data, memoranda,
customer lists, notes, programs and other papers and items, and reproductions
thereof relating to the foregoing matters) in Employee's possession or control,
shall be immediately returned to the Company.

            (c)   Employee hereby confirms that Employee is not bound by the
terms of any agreement with any previous employer or other party that restricts
in any way Employee's use or disclosure of information or Employee's engagement
in any business. Employee represents to the Company that Employee's execution of
this Agreement, Employee's employment with the Company and the performance of
Employee's proposed duties for the Company will not violate any obligations
Employee may have to any such previous employer or other party. In Employee's
work for the Company, Employee will not disclose or make use of any information
in violation of any agreements with or rights of any such previous employer or
other party, and Employee will not bring to the premises of the Company any
copies or other tangible embodiments of non-public information belonging to or
obtained from any such previous employment or other party.

            (d)   During and after Employee's employment, Employee shall
cooperate fully with the Company in the defense or prosecution of any claims or
actions now in existence or which may be brought in the future against or on
behalf of the Company that relate to events or occurrences that transpired while
Employee was employed by the Company. Employee's full cooperation in connection
with such claims or actions shall include, but not be limited to, being
available to meet with counsel to prepare for discovery or trial and to act as a
witness on behalf of the Company at mutually convenient times. During and after
Employee's employment, Employee also shall cooperate fully with the Company in
connection with any investigation or review of any federal, state or local
regulatory authority as any such investigation or review relates to

                                        7

<PAGE>

events or occurrences that transpired while Employee was employed by the
Company. The Company shall reimburse Employee for any reasonable out-of-pocket
expenses incurred in connection with Employee's performance of obligations
pursuant to this Section 7(d).

            (e)   Employee recognizes that the Company and its affiliates
possess a proprietary interest in all of the information described in Section
7(b) and have the exclusive right and privilege to use, protect by copyright,
patent or trademark, or otherwise exploit the processes, ideas and concepts
described therein to the exclusion of Employee, except as otherwise agreed
between the Company and Employee in writing. Employee expressly agrees that any
products, inventions, discoveries or improvements made by Employee or Employee's
agents or affiliates in the course of Employee's employment, including any of
the foregoing which is based on or arises out of the information described in
Section 7(b), shall be the property of and inure to the exclusive benefit of the
Company. Employee further agrees that any and all products, inventions,
discoveries or improvements developed by Employee (whether or not able to be
protected by copyright, patent or trademark) during the course of his
employment, or involving the use of the time, materials or other resources of
the Company or any of its affiliates, shall be promptly disclosed to the Company
and shall become the exclusive property of the Company, and Employee shall
execute and deliver any and all documents necessary or appropriate to implement
the foregoing. Pursuant to the Illinois Employee Patent Act, this paragraph does
not apply to any invention for which no equipment, supplies, facility or trade
secret information of the Company was used and which was developed entirely on
the Employee's own time, unless (a) the invention relates to (i) the business of
the Company or (ii) the Company's actually or demonstrably anticipated research
or development or (b) the invention results from any work performed by the
undersigned for the Company.

            (f)   Employee agrees, while he is employed by the Company, to offer
or otherwise make known or available to it, as directed by the Board of
Directors of the Company and without additional compensation or consideration,
any business prospects, contracts or other business opportunities that Employee
may discover, find, develop or otherwise have available to Employee in the
Company's general industry and further agrees that any such prospects, contacts
or other business opportunities shall be the property of the Company.

            (g)   Employee acknowledges that the provisions of this Section 7
are an integral part of Employee's employment arrangements with the Company.

            (h)   For purposes of this Agreement:

                  (i) the term "Confidential Information" shall mean information
            belonging to the Company which is of value to the Company or with
            respect to which Company has right in the course of conducting its
            business and the disclosure of which could result in a competitive
            or other

                                        8

<PAGE>

            disadvantage to the Company. Confidential Information includes
            information, whether or not patentable or copyrightable, in written,
            oral, electronic or other tangible or intangible forms, stored in
            any medium, including, by way of example and without limitation,
            trade secrets, ideas, concepts, designs, configurations,
            specifications, drawings, blueprints, diagrams, models, prototypes,
            samples, flow charts processes, techniques, formulas, software,
            improvements, inventions, data, know-how, discoveries, copyrightable
            materials, marketing plans and strategies, sales and financial
            reports and forecasts, customer lists, studies, reports, records,
            books, contracts, instruments, surveys, computer disks, diskettes,
            tapes, computer programs and business plans, prospects and
            opportunities (such as possible acquisitions or dispositions of
            businesses or facilities) which have been discussed or considered by
            the management of the Company. Confidential Information includes
            information developed by Employee in the course of Employee's
            employment by the Company, as well as other information to which
            Employee may have access in connection with Employee's employment.
            Confidential Information also includes the confidential information
            of others with which the Company has a business relationship.
            Notwithstanding the foregoing, Confidential Information does not
            include information in the public domain, unless due to breach of
            Employee's duties under Section 7(b).

      8.    Parties in Interest; Certain Remedies. It is specifically understood
and agreed that this Agreement is intended to confer a benefit, directly or
indirectly, on the Company and its direct and indirect subsidiaries and
affiliates, and that any breach of the provisions of this Agreement by the
Employee or any of the Employee's affiliates will result in irreparable injury
to the Company and its subsidiaries and affiliates, that the remedy at law alone
will be an inadequate remedy for such breach and that, in addition to any other
remedy it may have, the Company or its subsidiaries and affiliates shall be
entitled to enforce the specific performance of this Agreement by the Employee
through both temporary and permanent injunctive relief without the necessity of
posting a bond or proving actual damages, but without limitation of their right
to damages and any and all other remedies available to them, it being understood
that injunctive relief is in addition to, and not in lieu of, such other
remedies.

      9.    Dispute Resolution.

            (a)   All disputes, claims, or controversies arising out of or
relating to this Agreement or any other agreement executed and delivered
pursuant to this Agreement or the negotiation, validity or performance hereof
and thereof or the transactions contemplated hereby and thereby, or the rights
and obligations of the parties hereunder or thereunder, that are not resolved by
mutual agreement shall be resolved solely and exclusively by binding arbitration
to be conducted before JAMS/Endispute, Inc. or its successor. The arbitration
shall be held in Chicago, Illinois before a single

                                        9

<PAGE>

arbitrator and shall be conducted in accordance with the rules and regulations
promulgated by JAMS/Endispute, Inc. unless specifically modified herein.

            (b)   The parties covenant and agree that the arbitration shall
commence within one hundred eighty (180) days of the date on which a written
demand for arbitration is filed by any party hereto. In connection with the
arbitration proceeding, the arbitrator shall have the power to order the
production of documents by each party and any third-party witnesses. In
addition, each party may take up to three depositions as of right, and the
arbitrator may in his or her discretion allow additional depositions upon good
cause shown by the moving party. However, the arbitrator shall not have the
power to order the answering of interrogatories or the response to requests for
admission. In connection with any arbitration, each party shall provide to the
other, no later than seven (7) business days before the date of the arbitration,
the identity of all persons that may testify at the arbitration and a copy of
all documents that may be introduced at the arbitration or considered or used by
a party's witness or expert. The arbitrator's decision and award shall be made
and delivered within six (6) months of the selection of the arbitrator. The
arbitrator's decision shall set forth a reasoned basis for any award of damages
or finding of liability. The arbitrator shall not have power to award damages in
excess of actual compensatory damages and shall not multiply actual damages or
award punitive damages or any other damages that are specifically excluded under
this Agreement, and each party hereby irrevocably waives any claim to such
damages.

            (c)   The parties covenant and agree that they will participate in
the arbitration in good faith and that they will, except as provided below, (i)
bear their own attorneys' fees, costs and expenses in connection with the
arbitration, and (ii) share equally in the fees and expenses charged by
JAMS/Endispute, Inc. The arbitrator may in his or her discretion assess costs
and expenses (including the reasonable legal fees and expenses of the prevailing
party) against any party to a proceeding. Any party unsuccessfully refusing to
comply with an order of the arbitrators shall be liable for costs and expenses,
including attorneys' fees, incurred by the other party in enforcing the award.
This Section 9(c) applies equally to requests for temporary, preliminary or
permanent injunctive relief, except that in the case of temporary or preliminary
injunctive relief any party may proceed in court without prior arbitration for
the purpose of avoiding immediate and irreparable harm or to enforce the
provisions of Section 7.

            (d)   Each of the parties hereto irrevocably and unconditionally
consents to the exclusive jurisdiction of JAMS/Endispute, Inc. to resolve all
disputes, claims or controversies arising out of or relating to this Agreement
or any other agreement executed and delivered pursuant to this Agreement or the
negotiation, validity or performance hereof and thereof, or the transactions
contemplated hereby and thereby, or the rights and obligations of the parties
hereunder or thereunder, and further consents to the sole and exclusive
jurisdiction of the courts of State of California and/or the State of Illinois
for the purposes of enforcing the arbitration provisions of Section 8 of this
Agreement. Each party further irrevocably waives any objection to proceeding
before JAMS/Endispute, Inc. based upon lack of personal jurisdiction or to the
laying of venue and further irrevocably

                                       10

<PAGE>

and unconditionally waives and agrees not to make a claim in any court that
arbitration before JAMS/Endispute, Inc. has been brought in an inconvenient
forum. Each of the parties hereto hereby consents to service of process by
registered mail at the address to which notices are to be given. Each of the
parties hereto agrees that its or his submission to jurisdiction and its or his
consent to service of process by mail is made for the express benefit of the
other parties hereto.

      10.   Notices. All notices, requests, demands and other communications
hereunder shall be in writing and shall be deemed to have been duly given if
delivered personally or mailed by certified or registered mail (return receipt
requested) as follows:

      To the Company: Eagle Test Systems, Inc.
                      620 South Butterfield Road
                      Mundelin, IL 60060-4483
                      Attention: Board of Directors

      To Employee:    Leonard Foxman
                      1929 Browning Ct.
                      Highland Park, IL 60035

or to such other address of which any party may notify the other parties as
provided above. Notices shall be effective as of the date of such delivery or
mailing.

      11.   Scope of Agreement. The parties acknowledge that the time, scope,
geographic area and other provisions of Section 7 have been specifically
negotiated by sophisticated parties and agree that all such provisions are
reasonable under the circumstances of the transactions contemplated hereby, and
are given as an integral and essential part of the transactions contemplated
hereby. The Employee has independently consulted with counsel and has been
advised in all respects concerning the reasonableness and propriety of the
covenants contained herein, with specific regard to the business to be conducted
by Company and its subsidiaries and affiliates, and represents that the
Agreement is intended to be, and shall be, fully enforceable and effective in
accordance with its terms.

      12.   Severability. In the event that any covenant contained in this
Agreement shall be determined by any court of competent jurisdiction to be
unenforceable by reason of its extending for too great a period of time or over
too great a geographical area or by reason of its being too extensive in any
other respect, it shall be interpreted to extend only over the maximum period of
time for which it may be enforceable and/or over the maximum geographical area
as to which it may be enforceable and/or to the maximum extent in all other
respects as to which it may be enforceable, all as determined by such court in
such action. The existence of any claim or cause of action which the Employee
may have against the Company or any of its subsidiaries or affiliates shall not
constitute a defense or bar to the enforcement of any of the provisions of this
Agreement.

                                       11

      13.   Miscellaneous. This Agreement shall be governed by and construed
under the laws of the State of Illinois, without consideration of its choice of
law provisions, and shall not be amended, modified or discharged in whole or in
part except by an agreement in writing signed by both of the parties hereto. The
failure of either of the parties to require the performance of a term or
obligation or to exercise any right under this Agreement or the waiver of any
breach hereunder shall not prevent subsequent enforcement of such term or
obligation or exercise of such right or the enforcement at any time of any other
right hereunder or be deemed a waiver of any subsequent breach of the provision
so breached, or of any other breach hereunder. This Agreement shall inure to the
benefit of, and be binding upon and assignable to, successors of the Company by
way of merger, consolidation or sale and may not be assigned by Employee. This
Agreement supersedes and terminates all prior understandings and agreements
