                                  PLEXUS CORP.

                           CHANGE OF CONTROL AGREEMENT



         This AGREEMENT (the "Agreement") is made as of the 1st day of October,
2003, by and between PLEXUS CORP., a Wisconsin corporation (the "Company") and
______________________ employed as the ___________ at Plexus Corp. (the
"Executive").

         The Board of Directors of the Company (the "Board"), has determined
that it is in the best interests of the Company and its shareholders to assure
that the Company will have the continued dedication of the Executive,
notwithstanding the possibility, threat or occurrence of a Change of Control (as
defined below) of the Company. The Board believes it is imperative to diminish
the inevitable distraction of the Executive by virtue of the personal
uncertainties and risks created by a pending or threatened Change of Control and
to encourage the Executive's full attention and dedication to the Company
currently and in the event of any threatened or pending Change of Control, and
to provide the Executive with compensation and benefits arrangements upon a
Change of Control which ensure that the compensation and benefits expectations
of the Executive will be satisfied and which are competitive with those of other
corporations. The Company and the Executive have previously entered into a
Change of Control Agreement, which they now wish to supersede in its entirety.

         NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS:

         1. Certain Definitions.

                  (a) The "Effective Date" shall mean the first date during the
Change of Control Period (as defined in Section 1(b)) on which a Change of
Control (as defined in Section 2) occurs. Anything in this Agreement to the
contrary notwithstanding, if a Change of Control occurs and if the Executive's
employment with the Company or this Agreement is terminated prior to the date on
which the Change of Control occurs, and if it is reasonably demonstrated by the
Executive that such termination of employment or of this Agreement (i) was at
the request of a third party who has taken steps reasonably calculated to effect
a Change of Control or (ii) otherwise arose in connection with or anticipation
of a Change of Control, then for all purposes of this Agreement the "Effective
Date" shall mean the date immediately prior to the date of such termination of
employment or purported termination of this Agreement.

                  (b) The "Change of Control Period" shall mean the period
commencing on the date hereof and ending on the third anniversary of the date
hereof; provided, however, that commencing on the date one year after the date
hereof, and on each annual anniversary of such date (such date and each annual
anniversary thereof shall be hereinafter referred to as the "Renewal Date"),
unless previously terminated, the Change of Control Period shall be
automatically extended so as to terminate three years from such Renewal Date,
unless at least 60 days prior to the Renewal Date the Company's Board of
Directors has elected not to extend the Change of Control Period and has given
written notice of such intent to the Executive.

         2. Change of Control. For the purpose of this Agreement, a "Change of
Control" shall mean:

                  (a) any cash tender exchange offer; or



                                     Page 1
<PAGE>

                  (b) merger or other business combination; or

                  (c) a sale of assets or contested election; or

                  (d) any combination of the foregoing transactions (a
"Transaction"), and either or both of the following events occur:

                           (i) the persons who constituted the top management of
the Company (the Chief Executive Officer and the President) no longer serve in
their former capacity or no longer retain the authority to make decisions
concerning the employment of the Executive, and/or

                           (ii) the persons who were directors of the Company
before the Transaction shall cease to constitute a majority of the Board of
Directors of the Company (which term as used herein shall include any successor
of the Company), and/or

                           (iii) the current Board of Directors, by majority
action, declares that a Change of Control has occurred.

         3. Employment Period. The Company hereby agrees to continue the
Executive in its employ, and the Executive hereby agrees to remain in the employ
of the Company subject to the terms and conditions of this Agreement, for the
period commencing on the Effective Date and ending on the third anniversary of
such date; provided, however, that on each anniversary of the Effective Date the
term of the Agreement shall automatically be extended for an additional one-year
period (restoring the initial three-year term), unless either party notifies the
other party in writing at least 60 days prior to such anniversary. The term of
employment under this Agreement as effective from time to time shall be referred
to as the "Employment Period."

         4. Terms of Employment.

                  (a) Position and Duties.

                           (i) During the Employment Period, [a] the Executive's
position (including status, offices, titles and reporting requirements),
authority, duties and responsibilities shall be at least commensurate in all
material respects with the most significant of those held, exercised and
assigned at any time during the 120-day period immediately preceding the
Effective Date and [b] the Executive's services shall be performed at the
location where the Executive was employed immediately preceding the Effective
Date or any office or location less than 45 miles from such location.

                           (ii) During the Employment Period, and excluding any
periods of vacation and sick leave to which the Executive is entitled, the
Executive agrees to devote reasonable attention and time during normal business
hours to the business and affairs of the Company and, to the extent necessary to
discharge the responsibilities assigned to the Executive hereunder, to use the
Executive's reasonable best efforts to perform faithfully and efficiently such
responsibilities. During the Employment Period it shall not be a violation of
this Agreement for the Executive to [a] serve on corporate, civic or charitable
boards or committees, [b] deliver lectures, fulfill speaking engagements or
teach at educational institutions and [c] manage personal investments, so long
as such activities do not significantly interfere with the



                                     Page 2

<PAGE>


performance of the Executive's responsibilities as an employee of the Company in
accordance with this Agreement. It is expressly understood and agreed that to
the extent that any such activities have been conducted by the Executive prior
to the Effective Date, the continued conduct of such activities (or the conduct
of activities similar in nature and scope thereto) subsequent to the Effective
Date shall not thereafter be deemed to interfere with the performance of the
Executive's responsibilities to the Company.

                  (b) Compensation.

                           (i) Base Salary. During the Employment Period, the
Executive shall receive an annual base salary ("Annual Base Salary") at least
equal to base salary paid or payable, including any base salary which has been
earned but deferred, to the Executive by the Company and its affiliated
companies as reflected on the Company's records immediately prior to the
Effective Date and immediately prior to entering into an agreement with any
other party that could lead to a Change in Control, excluding any temporary
salary adjustment, such as a temporary salary reduction. During the Employment
Period, the Annual Base Salary shall be reviewed at least annually for possible
increase. Any increase in Annual Base Salary shall not serve to limit or reduce
any other obligation to the Executive under this Agreement. Annual Base Salary
shall not be reduced after any such increase and the term Annual Base Salary as
utilized in this Agreement shall refer to Annual Base Salary as so increased. As
used in this Agreement, the term "affiliated companies" shall include any
company controlled by, controlling or under common control with the Company.

                           (ii) Annual Bonus. In addition to Annual Base Salary,
the Executive shall be eligible to participate in any bonus plan sponsored by
the Company, on a basis consistent with that of other comparable employees.

                           (iii) Welfare Benefit Plans. During the Employment
Period, the Executive and/or the Executive's family, as the case may be, shall
be eligible for participation in and shall receive all benefits under welfare
benefit plans, practices, policies and programs provided by the Company and its
affiliated companies (including, without limitation, medical, prescription,
dental, disability, salary continuance, employee life, group life, accidental
death and travel accident insurance plans and programs) to the extent applicable
generally to other peer executives of the Company and its affiliated companies,
but in no event shall such plans, practices, policies and programs provide the
Executive with benefits which are less favorable in the aggregate, than the most
favorable of such plans, practices, policies and programs provided generally at
any time after the Effective Date to other peer executives of the Company and
its affiliated companies.

                           (iv) Other Benefits. During the Employment Period,
the Executive shall be entitled to participate in all fringe benefits, deferred
compensation programs, expense reimbursement programs, vacation, company car or
car allowance, as applicable (if Executive was receiving such benefit prior to
the Change of Control), incentive, savings and retirement plans (including, but
not limited to the 401(k) Plan and Employee Stock Purchase Plan), practices,
policies and programs applicable generally to other peer executives of the
Company and its affiliated companies, but in no event shall such plans,
practices, policies and programs provide the Executive with benefits which are
less favorable, in the aggregate, than the most


                                     Page 3

<PAGE>


favorable of those provided generally at any time after the Effective Date to
other peer executives of the Company and its affiliated companies.

                           (v) Stock Option Grants. During the Employment
Period, the Executive shall receive annual stock option grants (or other types
of long-term incentive compensation) with a value no less than the value of the
last stock option grant received by the Executive immediately preceding the
Effective Date.

         5. Termination of Employment.

                  (a) Death or Disability. The Executive's employment shall
terminate automatically upon the Executive's death during the Employment Period.
If the Company determines in good faith that the Disability of the Executive has
occurred during the Employment Period (pursuant to the definition of Disability
set forth below), it may give to the Executive written notice in accordance with
Section 12(b) of this Agreement of its intention to terminate the Executive's
employment. In such event, the Executive's employment with the Company shall
terminate effective on the 30th day after receipt of such notice by the
Executive (the "Disability Effective Date"), provided that, within the 30 days
after such receipt, the Executive shall not have returned to full-time
performance of the Executive's duties. For purposes of this Agreement,
"Disability" shall mean the absence of the Executive from the Executive's duties
with the Company on a full-time basis for 180 consecutive business days as a
result of incapacity due to mental or physical illness which is determined to be
total and permanent by a physician selected by the Company or its insurers and
acceptable to the Executive or the Executive's legal representative (such
agreement as to acceptability not to be withheld unreasonably).

                  (b) Cause. The Company may terminate the Executive's
employment during the Employment Period for Cause. For the sole and exclusive
purposes of this Agreement, "Cause" shall mean:

                           (i) The willful and continued failure of the
Executive to perform substantially the Executive's duties with the Company or
one of its affiliates (other than any such failure resulting from incapacity due
to physical or mental illness), after a written demand for substantial
performance is delivered to the Executive by the Board, the Chief Executive
Officer of the Company or the President of the Company which specifically
identifies the manner in which the Board, the Chief Executive Officer or the
President believes that the Executive has not substantially performed the
Executive's duties, or

                           (ii) The willful engaging by the Executive in illegal
conduct or gross misconduct which is materially and demonstrably injurious to
the Company.

         For purposes of this provision, no act or failure to act, on the part
of the Executive, shall be considered "willful" unless it is done, or omitted to
be done, by the Executive in bad faith or without reasonable belief that the
Executive's action or omission was in the best interests of the Company. Any
act, or failure to act, based upon authority given pursuant to a resolution duly
adopted by the Board or upon the instructions of the Chief Executive Officer or
a senior officer of the Company or based upon the advice of counsel for the
Company shall be conclusively presumed to be done, or omitted to be done, by the
Executive in good faith and in the best interests of the Company. The cessation
of employment of the Executive shall not be deemed to




                                     Page 4
<PAGE>



be for Cause unless and until there shall have been delivered to the Executive a
copy of a resolution duly adopted by the affirmative vote of not less than
three-quarters of the entire membership of the Board at a meeting of the Board
called and held for such purpose (after reasonable notice is provided to the
Executive and the Executive is given an opportunity, together with counsel, to
be heard before the Board), finding that, in the good faith opinion of the
Board, the Executive is guilty of the conduct described in subparagraph (i) or
(ii) above, and specifying the particulars thereof in detail.

                  (c) Good Reason. The Executive's employment may be terminated
by the Executive for Good Reason. For the sole and exclusive purposes of this
Agreement, "Good Reason" shall mean:

                           (i) The assignment to the Executive of any duties
inconsistent in any respect with the Executive's position (including status,
offices, titles and reporting requirements), authority, duties or
responsibilities as contemplated by Section 4(a) of this Agreement, or any other
action by the Company which results in a diminution in such position, authority,
duties or responsibilities, excluding for this purpose an isolated,
insubstantial and inadvertent action not taken in bad faith and which is
remedied by the Company promptly after receipt of notice thereof given by the
Executive;

                           (ii) Any failure by the Company to comply with any of
the provisions of Section 4(b) of this Agreement, other than an isolated,
insubstantial and inadvertent failure not occurring in bad faith and which is
remedied by the Company promptly after receipt of notice thereof given by the
Executive;

                           (iii) The Company's requiring the Executive to be
based at any office or location other than as provided in Section 4(a)(i)(b)
hereof or the Company's requiring the Executive to travel on Company business to
a substantially greater extent than required immediately prior to the Effective
Date; (iv) Any purported termination by the Company of the Executive's
employment otherwise than as expressly permitted by this Agreement; or

                           (v) Any failure by the Company to comply with and
satisfy Section 11(c) of this Agreement.

For purposes of this Section 5(c), any good faith determination of "Good Reason"
made by the Executive shall be conclusive. Anything in this Agreement to the
contrary notwithstanding, a termination by the Executive for any reason during
the 30-day period immediately following the first anniversary of the Effective
Date shall be deemed to be a termination for Good Reason for all purposes of
this Agreement.

                  (d) Notice of Termination. Any termination by the Company for
Cause, or by the Executive for Good Reason, shall be communicated by Notice of
Termination to the other party hereto given in accordance with Section 12(b) of
this Agreement. For purposes of this Agreement, a "Notice of Termination" means
a written notice which (i) indicates the specific termination provision in this
Agreement relied upon, (ii) to the extent applicable, sets forth in reasonable
detail the facts and circumstances claimed to provide a basis for termination of
the Executive's employment under the provision so indicated, and (iii) if the
Date of Termination (as




                                     Page 5

<PAGE>


defined below) is other than the date of receipt of such notice, specifies the
termination date (which date shall be not more than thirty days after the giving
of such notice). The failure by the Executive or the Company to set forth in the
Notice of Termination any fact or circumstance which contributes to a showing of
Good Reason or Cause shall not waive any right of the Executive or the Company,
respectively, hereunder or preclude the Executive or the Company, respectively,
from asserting such fact or circumstance in enforcing the Executive's or the
Company's rights hereunder.

                  (e) Date of Termination. "Date of Termination" means (i) if
the Executive's employment is terminated by the Company for Cause, or by the
Executive for Good Reason, the date of receipt of the Notice of Termination or
any later date specified therein, as the case may be, (ii) if the Executive's
employment is terminated by the Company other than for Cause or Disability, the
Date of Termination shall be the date on which the Company notifies the
Executive of such termination, and (iii) if the Executive's employment is
terminated by reason of death or Disability, the Date of Termination shall be
the date of death of the Executive or the Disability Effective Date, as the case
may be.

         6. Obligations of the Company upon Termination.

                  (a) Good Reason; Other Than for Cause, Death or Disability.
If, during the Employment Period, the Company shall terminate the Executive's
employment other than for Cause, death or Disability or the Executive shall
terminate employment for Good Reason:

                           (i) The Company shall pay to the Executive in a lump
sum in cash within 30 days after the Date of Termination the aggregate of the
following amounts:

                                    [a] The sum of [i] the Executive's Annual
Base Salary through the Date of Termination to the extent not theretofore paid,
[ii] the Annual Target Bonus payable as provided for in the Company's current
Annual Bonus Plan, pro-rated through the Date of Termination using a fraction,
the numerator of which is the number of days in the current fiscal year through
the Date of Termination, and the denominator of which is 365 and [iii] any
compensation previously deferred by the Executive (together with any accrued
interest or earnings thereon) and any accrued vacation pay, in each case to the
extent not theretofore paid (the sum of the amounts described in clauses [i],
[ii] and [iii] shall be hereinafter referred to as the "Accrued Obligations");
and

                                    [b] An amount equal to the sum of (i) the
product of three times the Executive's Annual Base Salary and (ii) three times
the Annual Target Bonus as provided for in the Company's current Annual Bonus
Plan; and

                                    [c] An amount equal to the difference
between [i] the actuarial equivalent of the benefit (utilizing actuarial
assumptions no less favorable to the Executive than those in effect under the
Retirement Plan (as defined below) immediately prior to the Effective Date)
under any qualified retirement plan in which the Executive participates (the
"Retirement Plan") and any excess or supplemental retirement plan or
nonqualified deferred compensation plan in which the Executive participates
(together, the "SERP") which the Executive would receive if the Executive's
employment continued for three years after the Date of Termination assuming for
this purpose that all accrued benefits are fully vested, and, assuming that
Executive's compensation in each of the three years is equal to Executive's
compensation in the


                                     Page 6

<PAGE>


last full fiscal year prior to the Date of Termination, and [ii] the actuarial
equivalent of the Executive's actual benefit (paid or payable), if any, under
any Retirement Plan and the SERP as of the Date of Termination;

                           (ii) For three years after the Executive's Date of
Termination, or such longer period as may be provided by the terms of the
appropriate plan, program, practice or policy, the Company shall continue
benefits to the Executive and/or the Executive's family at least equal to those
which would have been provided to them in accordance with the plans, programs,
practices and policies described in Section 4(b)(iii) of this Agreement if the
Executive's employment had not been terminated in accordance with the most
favorable plans, practices, programs or policies of the Company and its
affiliated companies applicable generally to other peer executives and their
families, provided, however, that if the Executive becomes reemployed with
another employer and is eligible to receive medical or other welfare benefits
under another employer provided plan, the medical and other welfare benefits
described herein shall be secondary to those provided under such other plan
during such applicable period of eligibility. For purposes of determining
eligibility (but not the time of commencement of benefits) of the Executive for
retiree benefits pursuant to such plans, practices, programs and policies, the
Executive shall be considered to have remained employed until two and one-half
years after the Date of Termination and to have retired on the last day of such
period;

                           (iii) The Company shall, at its sole expense as
incurred, provide the Executive with executive-level outplacement services for a
period of fifteen (15) months, the scope and provider of which shall be selected
by the Executive in his sole discretion; and

                           (iv) To the extent not theretofore paid or provided,
the Company shall timely pay or provide to the Executive any other amounts or
benefits required to be paid or provided or which the Executive is eligible to
receive under any plan, program, policy or practice or contract or agreement of
the Company and its affiliated companies (such other amounts and benefits shall
be hereinafter referred to as the "Other Benefits").

                  (b) Death. If the Executive's employment is terminated by
reason of the Executive's death during the Employment Period, this Agreement
shall terminate without further obligations to the Executive's legal
representatives under this Agreement, other than for payment of Accrued
Obligations and the timely payment or provision of Other Benefits. Accrued
Obligations shall be paid to the Executive's estate or beneficiary, as
applicable, in a lump sum in cash within 30 days of the Date of Termination.
With respect to the provision of Other Benefits, the term Other Benefits as
utilized in this Section 6(b) shall include, without limitation, and the
Executive's estate and/or beneficiaries shall be entitled to receive, benefits
at least equal to the most favorable benefits provided by the Company and
affiliated companies to the estates and beneficiaries of peer executives of the
Company and such affiliated companies under such plans, programs, practices and
policies relating to death benefits, if any, as in effect as of the date of the
Executive's death.

                  (c) Disability. If the Executive's employment is terminated by
reason of the Executive's Disability during the Employment Period, this
Agreement shall terminate without further obligations to the Executive, other
than for payment of Accrued Obligations and the timely payment or provision of
Other Benefits. Accrued Obligations shall be paid to the Executive in a lump sum
in cash within 30 days of the Date of Termination. With respect to the



                                     Page 7

<PAGE>


provision of Other Benefits, the term Other Benefits as utilized in this Section
6(c) shall include, and the Executive shall be entitled after the Disability
Effective Date to receive, disability and other benefits at least equal to the
most favorable of those generally provided by the Company and its affiliated
companies to disabled executives and/or their families in accordance with such
plans, programs, practices and policies relating to disability, if any, as in
effect generally with respect to other peer executives and their families at any
time after the Effective Date.

                  (d) Cause; Other than for Good Reason. If the Executive's
employment shall be terminated for Cause during the Employment Period, this
Agreement shall terminate without further obligations to the Executive other
than the obligation to pay to the Executive (i) his Annual Base Salary through
the Date of Termination, (ii) the amount of any compensation previously deferred
by the Executive, and (iii) Other Benefits, in each case to the extent
theretofore unpaid. If the Executive voluntarily terminates employment during
the Employment Period, excluding a termination for Good Reason, this Agreement
shall terminate without further obligations to the Executive, other than for
Accrued Obligations and the timely payment or provision of Other Benefits. In
such case, all Accrued Obligations shall be paid to the Executive in a lump sum
in cash within 30 days of the Date of Termination.

         7. Nonexclusivity of Rights. Nothing in this Agreement shall prevent or
limit the Executive's continuing or future participation in any plan, program,
policy or practice provided by the Company or any of its affiliated companies
and for which the Executive may qualify, nor shall anything herein limit or
otherwise affect such rights as the Executive may have under any contract or
agreement with the Company or any of its affiliated companies. Amounts which are
vested benefits or which the Executive is otherwise entitled to receive under
any plan, policy, practice or program of or any contract or agreement with the
Company or any of its affiliated companies at or subsequent to the Date of
Termination shall be payable in accordance with such plan, policy, practice or
program or contract or agreement except as explicitly modified by this
Agreement.

         8. Full Settlement. The Company's obligation to make the payments
provided for in this Agreement and otherwise to perform its obligations
hereunder shall not be affected by any set-off, counterclaim, recoupment,
defense or other claim, right or action which the Company may have against the
Executive or others. The Executive shall not be obligated to seek other
employment or take any other action by way of mitigation of the amounts payable
to the Executive under any of the provisions of this Agreement. The Company
agrees to pay as incurred, to the full extent permitted by law, all legal fees
and expenses which the Executive may reasonably incur as a result of any contest
(regardless of the outcome thereof) by the Company, the Executive or others of
the validity or enforceability of, or liability under, any provision of this
Agreement or any guarantee of performance thereof (including as a result of any
contest by the Executive about the amount of any payment pursuant to this
Agreement), plus in each case interest on any delayed payment at the applicable
Federal rate provided for in Section 7872(f)(2)(A) of the Internal Revenue Code
of 1986, as amended (the "Code").

         9. Certain Additional Payments by the Company.

                  (a) Anything in this Agreement to the contrary
notwithstanding, in the event it shall be determined that any payment or
distribution by the Company to or for the benefit of the Executive (whether paid
or payable or distributed or distributable pursuant to the terms of this



                                     Page 8

<PAGE>


Agreement or otherwise, but determined without regard to any additional payments
required under this Section 9) (a "Payment") would be subject to the excise tax
imposed by Section 4999 of the Code or any interest or penalties are incurred by
the Executive with respect to such excise tax (such excise tax, together with
any such interest and penalties, are hereinafter collectively referred to as the
"Excise Tax"), then the Executive shall be entitled to receive an additional
payment (a "Gross-Up Payment") in an amount such that after payment by the
Executive of all taxes (including any interest or penalties imposed with respect
to such taxes), including, without limitation, any income taxes (and any
interest and penalties imposed with respect thereto) and Excise Tax imposed upon
the Gross-Up Payment, the Executive retains an amount of the Gross-Up Payment
equal to the Excise Tax imposed upon the Payments.

                  (b) Subject to the provisions of Section 9(c), all
determinations required to be made under this Section 9, including whether and
when a Gross-Up Payment is required and the amount of such Gross-Up Payment and
the assumptions to be utilized in arriving at such determination, shall be made
by such certified public accounting firm as may be designated by the Executive
(the "Accounting Firm") which shall provide detailed supporting calculations
both to the Company and the Executive within 15 business days of the receipt of
notice from the Executive that there has been a Payment, or such earlier time as
is requested by the Company. All fees and expenses of the Accounting Firm shall
be borne solely by the Company. Any Gross-Up Payment, as determined pursuant to
this Section 9, shall be paid by the Company to the Executive within five days
of the receipt of the Accounting Firm's determination. If the Accounting Firm
determines that no Excise Tax is payable by the Executive, it shall furnish the
Executive with a written opinion that failure to report the Excise Tax on the
Executive's applicable federal income tax return would not result in the
imposition of a negligence or similar penalty. Any determination by the
Accounting Firm shall be binding upon the Company and the Executive. As a result
of the uncertainty in the application of Section 4999 of the Code at the time of
the initial determination by the Accounting Firm hereunder, it is possible that
Gross-Up Payments which will not have been made by the Company should have been
made ("Underpayment"), consistent with the calculations required to be made
hereunder. In the event that the Company exhausts its remedies pursuant to
Section 9(c) and the Executive thereafter is required to make a payment of any
Excise Tax, the Accounting Firm shall determine the amount of the Underpayment
that has occurred and any such Underpayment shall be promptly paid by the
Company to or for the benefit of the Executive.

                  (c) The Executive shall notify the Company in writing of any
claim by the Internal Revenue Service that, if successful, would require the
payment by the Company of the Gross-Up Payment. Such notification shall be given
as soon as practicable but no later than ten business days after the Executive
is informed in writing of such claim and shall apprise the Company of the nature
of such claim and the date on which such claim is requested to be paid. The
Executive shall not pay such claim prior to the expiration of the 30-day period
following the date on which it gives such notice to the Company (or such shorter
period ending on the date that any payment of taxes with respect to such claim
is due). If the Company notifies the Executive in writing prior to the
expiration of such period that it desires to contest such claim, the Executive
shall:

                           (i) Give the Company any information reasonably
requested by the Company relating to such claim,


                                     Page 9

<PAGE>


                           (ii) Take such action in connection with contesting
such claim as the Company shall reasonably request in writing from time to time,
including, without limitation, accepting legal representation with respect to
such claim by an attorney reasonably selected by the Company,

                           (iii) Cooperate with the Company in good faith in
order effectively to contest such claim, and

                           (iv) Permit the Company to participate in any
proceedings relating to such claim; provided, however, that the Company shall
bear and pay directly all costs and expenses (including additional interest and
penalties) incurred in connection with such contest and shall indemnify and hold
the Executive harmless, on an after-tax basis, for any Excise Tax or income tax
(including interest and penalties with respect thereto) imposed as a result of
such representation and payment of costs and expenses. Without limitation on the
foregoing provisions of this Section 9(c), the Company shall control all
proceedings taken in connection with such contest and, at its sole option, may
pursue or forgo any and all administrative appeals, proceedings, hearings and
conferences with the taxing authority in respect of such claim and may, at its
sole option, either direct the Executive to pay the tax claimed and sue for a
refund or contest the claim in any permissible manner, and the Executive agrees
to prosecute such contest to a determination before any administrative tribunal,
in a court of initial jurisdiction and in one or more appellate courts, as the
Company shall determine; provided, however, that if the Company directs the
Executive to pay such claim and sue for a refund, the Company shall advance the
amount of such payment to the Executive, on an interest-free basis and shall
indemnify and hold the Executive harmless, on an after-tax basis, from any
Excise Tax or income tax (including interest or penalties with respect thereto)
imposed with respect to such advance or with respect to any imputed income with
respect to such advance; and further provided that any extension of the statute
of limitations relating to payment of taxes for the taxable year of the
Executive with respect to which such contested amount is claimed to be due is
limited solely to such contested amount. Furthermore, the Company's control of
the contest shall be limited to issues with respect to which a Gross-Up Payment
would be payable hereunder and the Executive shall be entitled to settle or
contest, as the case may be, any other issue raised by the Internal Revenue
Service or any other taxing authority.

                  (d) If, after the receipt by the Executive of an amount
advanced by the Company pursuant to Section 9(c), the Executive becomes entitled
to receive any refund with respect to such claim, the Executive shall (subject
to the Company's complying with the requirements of Section 9(c)) promptly pay
to the Company the amount of such refund (together with any interest paid or
credited thereon after taxes applicable thereto). If, after the receipt by the
Executive of an amount advanced by the Company pursuant to Section 9(c), a
determination is made that the Executive shall not be entitled to any refund
with respect to such claim and the Company does not notify the Executive in
writing of its intent to contest such denial of refund prior to the expiration
of 30 days after such determination, then such advance shall be forgiven and
shall not be required to be repaid and the amount of such advance shall offset,
to the extent thereof, the amount of Gross-Up Payment required to be paid.

         10. Confidential Information. The Executive shall hold in a fiduciary
capacity for the benefit of the Company all secret or confidential information,
knowledge or data relating to the Company or any of its affiliated companies,
and their respective businesses, which shall have



                                     Page 10

<PAGE>


been obtained by the Executive during the Executive's employment by the Company
or any of its affiliated companies and which shall not be or become public
knowledge (other than by acts by the Executive or representatives of the
Executive in violation of this Agreement). After termination of the Executive's
employment with the Company, the Executive shall not, without the prior written
consent of the Company or as may otherwise be required by law or legal process,
communicate or divulge any such information, knowledge or data to anyone other
than the Company and those designated by it. In no event shall an asserted
violation of the provisions of this Section 10 constitute a basis for deferring
or withholding any amounts otherwise payable to the Executive under this
Agreement.


         11. Successors.

                  (a) This Agreement is personal to the Executive and without
the prior written consent of the Company shall not be assignable by the
Executive otherwise than by will or the laws of descent and distribution. This
Agreement shall inure to the benefit of and be enforceable by the Executive's
legal representatives.

                  (b) This Agreement shall inure to the benefit of and be
binding upon the Company and its successors and assigns.

                  (c) The Company will require any successor (whether direct or
indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business and/or assets of the Company to assume
expressly and agree to perform this Agreement in the same manner and to the same
extent that the Company would be required to perform it if no such succession
had taken place. As used in this Agreement, "Company" shall mean the Company as
hereinbefore defined and any successor to its business and/or assets as
aforesaid which assumes and agrees to perform this Agreement by operation of
law, or otherwise.

         12. Miscellaneous.

                  (a) This Agreement shall be governed by and construed in
accordance with the laws of the State of Wisconsin, without reference to
principles of conflict of laws. The captions of this Agreement are not part of
the provisions hereof and shall have no force or effect. This Agreement may not
be amended or modified otherwise than by a written agreement executed by the
parties hereto or their respective successors and legal representatives.

                  (b) All notices and other communications hereunder shall be in
writing and shall be given by hand delivery to the other party or by registered
or certified mail, return receipt requested, postage prepaid, addressed as

writing in accordance herewith. Notice and communications shall be effective
when actually received by the addressee.

provision of this Agreement.

this Agreement such Federal, state, local or foreign taxes as shall be required
to be withheld pursuant to any applicable law or regulation.

                  (e) The Executive's or the Company's failure to insist upon
strict compliance with any provision hereof or any other provision of this
Agreement or the failure to assert any right the Executive or the Company may
have hereunder, including, without limitation, the right of the Executive to
terminate employment for Good Reason pursuant to Section 5(c)(i)-(v) of this
Agreement, shall not be deemed to be a waiver of such provision or right or any
other provision or right of this Agreement.

                  (f) The Executive and the Company acknowledge that, except as
may otherwise be provided under any other written agreement between the
Executive and the Company, the employment of the Executive by the Company is "at
will" and, prior to the Effective Date, the Executive's employment and this
Agreement may be terminated by either the Executive or the Company at any time
prior to the Effective Date, in which case the Executive shall have no further
rights under this Agreement. From and after the Effective Date this Agreement
shall supersede any other agreement between the parties with respect to the
subject matter hereof.

         IN WITNESS WHEREOF, the Executive has hereunto set the Executive's hand
and, pursuant to the authorization from its Board of Directors, the Company has
caused these presents to be executed in its name on its behalf, all as of the
day and year first above written.
