                                     FORM OF
                             SUBSIDIARIES GUARANTEE

         GUARANTEE, dated as of December 1, 2000, made by each of the
corporations that are signatories hereto (the "Guarantors"), in favor of THE
CHASE MANHATTAN BANK, as administrative agent (in such capacity, the
"Administrative Agent"), for the banks and other financial institutions (the
"Lenders") from time to time parties to the Credit Agreement, dated as of
December 1, 2000 (as the same may be amended, supplemented or modified from time
to time, the "Credit Agreement"), among Sybron International Corporation, a
Wisconsin corporation (the "Borrower"), the Lenders, the Administrative Agent,
Bank One, NA, as Documentation Agent, Bank of America, N.A., as Syndication
Agent, and Chase Securities Inc., as Lead Arranger and Book Manager (in such
capacity, the "Arranger").

                                   WITNESSETH:

         WHEREAS, the Borrower and the Guarantors are members of the same
consolidated group of companies and engaged in related businesses, and each
Guarantor will derive substantial direct and indirect benefit from the making of
the Loans and the Letters of Credit (as defined in the Credit Agreement); and

         WHEREAS, it is a condition precedent to the obligation of the Lenders
to make their respective extensions of credit to the Borrower under the Credit
Agreement that the Guarantors shall have executed and delivered this Guarantee
to the Administrative Agent for the ratable benefit of the Lenders;

         NOW, THEREFORE, in consideration of the premises and to induce the
Administrative Agent and the Lenders to enter into the Credit Agreement and to
induce the Lenders to make their respective extensions of credit to the Borrower
under the Credit Agreement, the Guarantors hereby agree with the Administrative
Agent, for the ratable benefit of the Lenders, as follows:

Defined Terms. Unless otherwise defined herein, terms defined in the Credit
Agreement and used herein shall have the meanings given to them in the Credit
Agreement.

         As used herein "Obligations" means (i) the unpaid principal of and
interest on (including, without limitation, interest accruing after the maturity
of the Loans and interest accruing on or after the filing of any petition in
bankruptcy, or the commencement of any insolvency, reorganization or like
proceeding, relating to the Borrower, whether or not a claim for post-filing or
post-petition interest is allowed in such proceeding) the Notes and all other
obligations and liabilities of the Loan Parties to the Administrative Agent or
to the Lenders, whether direct or indirect, absolute or contingent, due or to
become due, or now existing or hereafter incurred, which may arise under, out
of, or in connection with, the Credit Agreement, the Notes, any other

                                                                               2

Loan Document and any other document made, delivered or given in connection
herewith or therewith, whether on account of principal, interest, reimbursement
obligations, fees, indemnities, costs, expenses (including, without limitation,
all fees and disbursements of counsel to the Administrative Agent or to the
Lenders) or otherwise and (ii) all obligations of the Borrower to any Lender or
any Affiliate of any Lender under or in connection with any Interest Rate
Agreement or foreign exchange contract.

         As used herein "Solvent", when used with respect to any Person, means
that, as of any date of determination, (a) the amount of the "present fair
saleable value" of the assets of such Person will, as of such date, exceed the
amount of all "liabilities of such Person, contingent or otherwise", as of such
date, as such quoted terms are determined in accordance with applicable federal
and state laws governing determinations of the insolvency of debtors, (b) the
present fair saleable value of the assets of such Person will, as of such date,
be greater than the amount that will be required to pay the liability of such
Person on its debts as such debts become absolute and matured, (c) such Person
will not have, as of such date, an unreasonably small amount of capital with
which to conduct its business, and (d) such Person will be able to pay its debts
as they mature. For purposes of this definition, (i) "debt" means liability on a
"claim", and (ii) "claim" means any (x) right to payment, whether or not such a
right is reduced to judgment, liquidated, unliquidated, fixed, contingent,
matured, unmatured, disputed, undisputed, legal, equitable, secured or unsecured
or (y) right to an equitable remedy for breach of performance if such breach
gives rise to a right to payment, whether or not such right to an equitable
remedy is reduced to judgment, fixed, contingent, matured or unmatured,
disputed, undisputed, secured or unsecured.

         The words "hereof," "herein" and "hereunder" and words of similar
import when used in this Guarantee shall refer to this Guarantee as a whole and
not to any particular provision of this Guarantee, and Section and paragraph
references are to this Guarantee unless otherwise specified.

         The meanings given to terms defined herein shall be equally applicable
to both the singular and plural forms of such terms.

Guarantee. Subject to the provisions of paragraph 2(b), each of the Guarantors
hereby, jointly and severally, unconditionally and irrevocably, guarantees to
the Administrative Agent, for the ratable benefit of the Lenders and their
respective successors, indorsees, transferees and assigns, the prompt and
complete payment and performance by the Borrower when due (whether at the stated
maturity, by acceleration or otherwise) of the Obligations.

         Anything herein or in any other Loan Document to the contrary
notwithstanding, the maximum liability of each Guarantor hereunder and under the
other Loan Documents shall in no event exceed the amount which can be guaranteed
by such Guarantor under applicable federal and state laws relating to the
insolvency of debtors.

                                                                               3

         Each Guarantor further agrees to pay any and all expenses (including,
without limitation, all fees and disbursements of counsel) which may be paid or
incurred by the Administrative Agent or any Lender in enforcing, or obtaining
advice of counsel in respect of, any rights with respect to, or collecting, any
or all of the Obligations and/or enforcing any rights with respect to, or
collecting against, such Guarantor under this Guarantee. This Guarantee shall
remain in full force and effect until the Obligations are paid in full and the
Commitments are terminated, notwithstanding that from time to time prior thereto
the Borrower may be free from any Obligations.

         Each Guarantor agrees that the Obligations may at any time and from
time to time exceed the amount of the liability of such Guarantor hereunder
without impairing this Guarantee or affecting the rights and remedies of the
Administrative Agent or any Lender hereunder.

         No payment or payments made by the Borrower, any of the Guarantors, any
other guarantor or any other Person or received or collected by the
Administrative Agent or any Lender from the Borrower, any of the Guarantors, any
other guarantor or any other Person by virtue of any action or proceeding or any
set-off or appropriation or application at any time or from time to time in
reduction of or in payment of the Obligations shall be deemed to modify, reduce,
release or otherwise affect the liability of any Guarantor hereunder which
shall, notwithstanding any such payment or payments other than payments made by
such Guarantor in respect of the Obligations or payments received or collected
from such Guarantor in respect of the Obligations, remain liable for the
Obligations up to the maximum liability of such Guarantor hereunder until the
Obligations are paid in full and the Commitments are terminated.

         Each Guarantor agrees that whenever, at any time, or from time to time,
it shall make any payment to the Administrative Agent or any Lender on account
of its liability hereunder, it will notify the Administrative Agent in writing
that such payment is made under this Guarantee for such purpose.

Right of Contribution. Each Guarantor hereby agrees that to the extent that a
Guarantor shall have paid more than its proportionate share of any payment made
hereunder, such Guarantor shall be entitled to seek and receive contribution
from and against any other Guarantor hereunder who has not paid its
proportionate share of such payment. Each Guarantor's right of contribution
shall be subject to the terms and conditions of Section 5 hereof. The provisions
of this Section shall in no respect limit the obligations and liabilities of any
Guarantor to the Administrative Agent and the Lenders, and each Guarantor shall
remain liable to the Administrative Agent and the Lenders for the full amount
guaranteed by such Guarantor hereunder.

Right of Set-off. Upon the occurrence of any Event of Default, each Guarantor
hereby irrevocably authorizes each Lender at any time and from time to time
without notice to such Guarantor or any other Guarantor, any such notice being
expressly waived by each Guarantor, to set-off and appropriate and apply any and
all deposits (general or special, time or demand, provisional or final), in any
currency, and any other credits, indebtedness or claims, in any currency, in
each case whether direct or indirect, absolute or contingent, matured or
unmatured, at any time held or owing by such Lender to or for the credit or the
account of such Guarantor, or any part thereof in such amounts as such Lender
may elect, against and on account of the

                                                                               4

obligations and liabilities of such Guarantor to such Lender hereunder and
claims of every nature and description of such Lender against such Guarantor, in
any currency, whether arising hereunder, under the Credit Agreement, any Note,
any Loan Document or otherwise, as such Lender may elect, whether or not the
Administrative Agent or any Lender has made any demand for payment and although
such obligations, liabilities and claims may be contingent or unmatured. The
Administrative Agent and each Lender shall notify such Guarantor promptly of any
such set-off and the application made by the Administrative Agent or such
Lender, provided that the failure to give such notice shall not affect the
validity of such set-off and application. The rights of the Administrative Agent
and each Lender under this Section are in addition to other rights and remedies
(including, without limitation, other rights of set-off) which the
Administrative Agent or such Lender may have.

No Subrogation. Notwithstanding any payment or payments made by any of the
Guarantors hereunder or any set-off or application of funds of any of the
Guarantors by any Lender, no Guarantor shall be entitled to be subrogated to any
of the rights of the Administrative Agent or any Lender against the Borrower or
any other Guarantor or any collateral security or guarantee or right of offset
held by any Lender for the payment of the Obligations, nor shall any Guarantor
seek or be entitled to seek any contribution or reimbursement from the Borrower
or any other Guarantor in respect of payments made by such Guarantor hereunder,
until all amounts owing to the Administrative Agent and the Lenders by the
Borrower on account of the Obligations are paid in full and the Commitments are
terminated. If any amount shall be paid to any Guarantor on account of such
subrogation rights at any time when all of the Obligations shall not have been
paid in full, such amount shall be held by such Guarantor in trust for the
Administrative Agent and the Lenders, segregated from other funds of such
Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned over
to the Administrative Agent in the exact form received by such Guarantor (duly
indorsed by such Guarantor to the Administrative Agent, if required), to be
applied against the Obligations, whether matured or unmatured, in such order as
the Administrative Agent may determine.

Amendments, etc. with respect to the Obligations; Waiver of Rights. Each
Guarantor shall remain obligated hereunder notwithstanding that, without any
reservation of rights against any Guarantor and without notice to or further
assent by any Guarantor, any demand for payment of any of the Obligations made
by the Administrative Agent or any Lender may be rescinded by such party and any
of the Obligations continued, and the Obligations, or the liability of any other
party upon or for any part thereof, or any collateral security or guarantee
therefor or right of offset with respect thereto, may, from time to time, in
whole or in part, be renewed, extended, amended, modified, accelerated,
compromised, waived, surrendered or released by the Administrative Agent or any
Lender, and the Credit Agreement, the Notes and the other Loan Documents and any
other documents executed and delivered in connection therewith may be amended,
modified, supplemented or terminated, in whole or in part, as the Administrative
Agent (or the Majority Lenders, as the case may be) may deem advisable from time
to time, and any collateral security, guarantee or right of offset at any time
held by the Administrative Agent or any Lender for the payment of the
Obligations may be sold, exchanged, waived, surrendered or released. Neither the
Administrative Agent nor any Lender shall have any obligation to protect,
secure, perfect or insure any Lien at any time held by it as security for the
Obligations or

                                                                               5

for this Guarantee or any property subject thereto. When making any demand
hereunder against any of the Guarantors, the Administrative Agent or any Lender
may, but shall be under no obligation to, make a similar demand on the Borrower
or any other Guarantor or guarantor, and any failure by the Administrative Agent
or any Lender to make any such demand or to collect any payments from the
Borrower or any such other Guarantor or guarantor or any release of the Borrower
or such other Guarantor or guarantor shall not relieve any of the Guarantors in
respect of which a demand or collection is not made or any of the Guarantors not
so released of their several obligations or liabilities hereunder, and shall not
impair or affect the rights and remedies, express or implied, or as a matter of
law, of the Administrative Agent or any Lender against any of the Guarantors.
For the purposes hereof "demand" shall include the commencement and continuance
of any legal proceedings.

Guarantee Absolute and Unconditional. Each Guarantor waives any and all notice
of the creation, renewal, extension or accrual of any of the Obligations and
notice of or proof of reliance by the Administrative Agent or any Lender upon
this Guarantee or acceptance of this Guarantee, the Obligations, and any of
them, shall conclusively be deemed to have been created, contracted or incurred,
or renewed, extended, amended or waived, in reliance upon this Guarantee; and
all dealings between the Borrower and any of the Guarantors, on the one hand,
and the Administrative Agent and the Lenders, on the other hand, likewise shall
be conclusively presumed to have been had or consummated in reliance upon this
Guarantee. Each Guarantor waives diligence, presentment, protest, demand for
payment and notice of default or nonpayment to or upon the Borrower or any of
the Guarantors with respect to the Obligations. Each Guarantor understands and
agrees that this Guarantee shall be construed as a continuing, absolute and
unconditional guarantee of payment without regard to (a) the validity,
regularity or enforceability of the Credit Agreement, any Note or any other Loan
Document, any of the Obligations or any other collateral security therefor or
guarantee or right of offset with respect thereto at any time or from time to
time held by the Administrative Agent or any Lender, (b) any defense, set-off or
counterclaim (other than a defense of payment or performance) which may at any
time be available to or be asserted by the Borrower against the Administrative
Agent or any Lender, or (c) any other circumstance whatsoever (with or without
notice to or knowledge of the Borrower or such Guarantor) which constitutes, or
might be construed to constitute, an equitable or legal discharge of the
Borrower for the Obligations, or of such Guarantor under this Guarantee, in
bankruptcy or in any other instance. When pursuing its rights and remedies
hereunder against any Guarantor, the Administrative Agent and any Lender may,
but shall be under no obligation to, pursue such rights and remedies as it may
have against the Borrower or any other Person or against any other collateral
security or guarantee for the Obligations or any right of offset with respect
thereto, and any failure by the Administrative Agent or any Lender to pursue
such other rights or remedies or to collect any payments from the Borrower or
any such other Person or to realize upon any such collateral security or
guarantee or to exercise any such right of offset, or any release of the
Borrower or any such other Person or any such collateral security, guarantee or
right of offset, shall not relieve such Guarantor of any liability hereunder,
and shall not impair or affect the rights and remedies, whether express, implied
or available as a matter of law, of the Administrative Agent and the Lenders
against such Guarantor. This Guarantee shall remain in full force and effect and
be binding in accordance with and to the extent of its terms upon each Guarantor
and the successors and assigns thereof, and shall inure to

                                                                               6

the benefit of the Administrative Agent and the Lenders, and their respective
successors, indorsees, transferees and assigns, until all the Obligations and
the obligations of each Guarantor under this Guarantee shall have been satisfied
by payment in full and the Commitments shall be terminated, notwithstanding that
from time to time during the term of the Credit Agreement the Borrower may be
free from any Obligations.

Reinstatement. This Guarantee shall continue to be effective, or be reinstated,
as the case may be, if at any time payment, or any part thereof, of any of the
Obligations is rescinded or must otherwise be restored or returned by the
Administrative Agent or any Lender upon the insolvency, bankruptcy, dissolution,
liquidation or reorganization of the Borrower or any Guarantor, or upon or as a
result of the appointment of a receiver, intervenor or conservator of, or
trustee or similar officer for, the Borrower or any Guarantor or any substantial
part of its property, or otherwise, all as though such payments had not been
made.

Payments. Each Guarantor hereby guarantees that payments hereunder will be paid
to the Administrative Agent without set-off or counterclaim in U.S. Dollars at
the office of the Administrative Agent located at 270 Park Avenue, New York, New
York 10017.

Representations and Warranties. Each Guarantor hereby represents and warrants
that:

         it is a corporation duly organized, validly existing and in good
standing (or similar concept under applicable law) under the laws of the
jurisdiction of its incorporation and has the corporate power and authority and
the legal right to own and operate its property, to lease the property it
operates and to conduct the business in which it is currently engaged;

         it has the corporate power and authority and the legal right to execute
and deliver, and to perform its obligations under, this Guarantee, and has taken
all necessary corporate action to authorize its execution, delivery and
performance of this Guarantee;

         this Guarantee constitutes a legal, valid and binding obligation of
such Guarantor enforceable in accordance with its terms, except as affected by
bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and
other similar laws relating to or affecting the enforcement of creditors' rights
generally, general equitable principles (whether considered in a proceeding in
equity or at law) and an implied covenant of good faith and fair dealing;

         the execution, delivery and performance of this Guarantee will not
violate any provision of any Requirement of Law or Contractual Obligation of
such Guarantor and will not result in or require the creation or imposition of
any Lien on any of the properties or revenues of such Guarantor pursuant to any
Requirement of Law or Contractual Obligation of the Guarantor;

         no consent or authorization of, filing with, or other act by or in
respect of, any arbitrator or Governmental Authority and no consent of any other
Person (including, without limitation, any stockholder or creditor of such
Guarantor) is required in connection with the execution, delivery, performance,
validity or enforceability of this Guarantee;

                                                                               7

         no litigation, investigation or proceeding of or before any arbitrator
or Governmental Authority is pending or, to the knowledge of such Guarantor,
threatened by or against such Guarantor or against any of its properties or
revenues (1) with respect to this Guarantee or any of the transactions
contemplated hereby or (2) which could reasonably be expected to have a Material
Adverse Effect;

         it has good record and marketable title in fee simple to, or a valid
leasehold interest in, all its real property, and good title to, or a valid
leasehold interest in, all its other property, and none of such property is
subject to any Lien of any nature whatsoever except as permitted by subsection
7.3 of the Credit Agreement; and

         it is, and after giving effect to the Transaction and the incurrence of
all Indebtedness and obligations being incurred in connection herewith and
therewith will be and will continue to be, Solvent (in the case of each material
Guarantor).

         Each Guarantor agrees that the foregoing representations and warranties
shall be deemed to have been made by such Guarantor on the date of each
borrowing by the Borrower under the Credit Agreement on and as of the relevant
Borrowing Date as though made hereunder on and as of such date.

Authority of Administrative Agent. Each Guarantor acknowledges that the rights
and responsibilities of the Administrative Agent under this Guarantee with
respect to any action taken by the Administrative Agent or the exercise or
non-exercise by the Administrative Agent of any option, right, request, judgment
or other right or remedy provided for herein or resulting or arising out of this
Guarantee shall, as between the Administrative Agent and the Lenders, be
governed by the Credit Agreement and by such other agreements with respect
thereto as may exist from time to time among them, but, as between the
Administrative Agent and such Guarantor, the Administrative Agent shall be
conclusively presumed to be acting as agent for the Lenders with full and valid
authority so to act or refrain from acting, and no Guarantor shall be under any
obligation, or entitlement, to make any inquiry respecting such authority.

Notices. All notices, requests and demands to or upon the Administrative Agent,
any Lender or any Guarantor to be effective shall be in writing (or by telex,
fax or similar electronic transfer confirmed in writing) and shall be deemed to
have been duly given or made (1) when delivered by hand or (2) if given by mail,
three days after deposited in the mails, postage prepaid, or (3) if by telex,
fax or similar electronic transfer, when sent and receipt has been confirmed,
addressed as follows:

         if to the Administrative Agent or any Lender, at its address or
transmission number for notices provided in or referred to in subsection 11.2 of
the Credit Agreement; and

Counterparts. This Guarantee may be executed by one or more of the Guarantors on
any number of separate counterparts, and all of said counterparts taken together
shall be deemed to constitute one and the same instrument. A set of the
counterparts of this Guarantee signed by all the Guarantors shall be lodged with
the Administrative Agent.

Severability. Any provision of this Guarantee which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

Integration. This Guarantee represents the agreement of each Guarantor with
respect to the subject matter hereof and there are no promises or
representations by the Administrative Agent or any Lender relative to the
subject matter hereof not reflected herein.

Amendments in Writing; No Waiver; Cumulative Remedies. a) None of the terms or
provisions of this Guarantee may be waived, amended, supplemented or otherwise
modified except by a written instrument executed by each Guarantor and the
Administrative Agent (other than supplements, in form and substance acceptable
to the Administrative Agent, for the purpose of adding new Guarantors), provided
that any provision of this Guarantee may be waived by the Administrative Agent
and the Lenders in a letter or agreement executed by the Administrative Agent or
by telex or facsimile transmission from the Administrative Agent.

         Neither the Administrative Agent nor any Lender shall by any act
(except by a written instrument pursuant to paragraph 16(a) hereof), delay,
indulgence, omission or otherwise be deemed to have waived any right or remedy
hereunder or to have acquiesced in any Default or Event of Default or in any
breach of any of the terms and conditions hereof. No failure to exercise, nor
any delay in exercising, on the part of the Administrative Agent or any Lender,
any right, power or privilege hereunder shall operate as a waiver thereof. No
single or partial exercise of any right, power or privilege hereunder shall
preclude any other or further exercise thereof or the exercise of any other
right, power or privilege. A waiver by the Administrative Agent or any Lender of
any right or remedy hereunder on any one occasion shall not be construed as a
bar to any right or remedy which the Administrative Agent or such Lender would
otherwise have on any future occasion.

         The rights and remedies herein provided are cumulative, may be
exercised singly or concurrently and are not exclusive of any other rights or
remedies provided by law.

Company business shall be first class.]

         3.       Termination of Employment.

                  (a) Death or Disability. Executive's employment shall
terminate automatically upon the Executive's death during the Employment Period.
The Company shall be entitled to terminate the Executive's employment because of
the Executive's Disability during the Employment Period. For the purpose of this
Agreement, "Disability" shall be deemed to have occurred if Executive shall have
been unable to perform his duties hereunder due to mental or physical incapacity
for a period of six (6) consecutive months. A termination of the Executive's
employment by the Company for Disability shall be communicated to the Executive
by written notice, and shall be effective on the 30th day after receipt of such
notice by the Executive (the "Disability Effective Date"), unless the Executive
returns to full-time performance of the Executive's duties before the Disability
Effective Date.

                  (b)      Termination by the Company for Cause.

                  (i) The Company may terminate the Executive's employment
during the Employment Period for Cause. For the purposes of this Agreement,
"Cause" shall be deemed to be breach of this Agreement, fraud, dishonesty,
competition with Company or any subsidiary of Company, unauthorized use of
Company's or any such subsidiary's trade secrets or confidential information or
continued gross neglect by Executive of the duties assigned to him by the Board
(if such neglect continues for thirty (30) days after notice by the Board to
Executive specifying the duties being neglected by Executive).

                  (ii) A termination of the Executive's employment for Cause
shall be not be effective unless it is accomplished in accordance with the
following procedures. The Company shall give the Executive written notice
("Notice of Termination for Cause") of its intention to terminate the
Executive's employment for Cause, setting forth in reasonable detail the
specific conduct of the Executive that it considers to constitute Cause and the
specific provision(s) of this Agreement on which it relies, and stating the
date, time and place of the Special Board Meeting for Cause. The "Special Board
Meeting for Cause" means a meeting of the Board called and held specifically for
the purpose of considering the Executive's termination for Cause, that takes
place not less than ten (10) nor more than twenty (20) business days after the
Executive receives the Notice of Termination for Cause. The Executive shall be
given an opportunity, together with counsel, to be heard at the Special Board
Meeting for Cause. The Executive's termination for Cause shall be effective when
and if a resolution is duly adopted at the Special Board Meeting for Cause by
affirmative vote of a majority of the entire membership of the Board, excluding
employee directors, stating that, in the good faith opinion of the Board,

                                        3

<PAGE>   4

the Executive is guilty of the conduct described in the Notice of Termination
for Cause and that such conduct constitutes Cause under this Agreement. The
failure to set forth any fact or circumstance in a Notice of Termination for
Cause shall not constitute a waiver of the right to assert, and shall not
preclude the Company from asserting, such fact or circumstance in an attempt to
enforce any right under or provision of this Agreement.

                  (c) Termination by Executive. Executive may terminate the
Employment Period at any time on or before December 31, 2001 upon one hundred
eighty (180) days' advance written notice to the Company. Executive may
terminate the Employment Period at any time after December 31, 2001 upon ninety
(90) days' advance written notice to the Company.

                                        4

<PAGE>   5

                  (d) Date of Termination. The "Date of Termination" means the
date of the Executive's death, the Disability Effective Date, the date on which
the Executive's employment is terminated by the Company for Cause, or the date
specified by the Executive in the case of a termination by Executive.

         4.       Obligations of the Company Upon Termination.

                  (a) Death and Disability. If the Executive's employment is
terminated by reason of the Executive's death or Disability during the
Employment Period, the Company shall pay to the Executive or, in the case of the
Executive's death, to the Executive's designated beneficiaries (or, if there is
no such beneficiary, to the Executive's estate or legal representative), in a
lump sum in cash within thirty (30) days after the Date of Termination, the sum
of the following amounts: (i) any portion of the Executive's base salary through
the Date of Termination that has not yet been paid; and (ii) an amount equal to
the base salary Executive would have received for the remainder of the
Employment Period. In addition, during the remainder of the Employment Period,
the Company shall arrange to provide Executive and his spouse with accident and
health insurance benefits substantially similar to those which Executive was
receiving or entitled to receive immediately prior to the termination. The
rights of Executive under any other Benefit Plan shall be determined by the
terms of such Benefit Plan. The Company shall have no further obligations under
this Agreement.

                  (b) By the Company For Cause; By the Executive. If the
Executive's employment is terminated by the Company for Cause or by the
Executive during the Employment Period, no further compensation shall be paid to
Executive after the Date of Termination; provided, however, that the rights of
Executive under any Benefit Plan shall be determined by the terms of such Plan.

         5.       Change in Control.

                  (a) Benefits Payable to Executive. If a Change in Control (as
hereinafter defined) shall have occurred and thereafter Executive's employment
with the Company is terminated by the Company without Cause or by the Executive
for Good Reason (as hereinafter defined) during the Employment Period, Executive
shall be entitled to the following benefits:

                  (i) The Company shall pay Executive his full base salary
through the date of termination at the rate in effect at the time, no later than
the fifth day following the date of termination, plus all other amounts to which
Executive is entitled under any stock option, incentive compensation and other
benefit plans of the Company applicable to Executive, at the time such payments
are due.

                  (ii) The Company shall pay as severance to Executive a
severance payment (the "Unadjusted Severance Payment") equal to three times
Executive's average salary and bonus in the five full calendar years immediately
prior to the Change in Control.

                                        5

<PAGE>   6

                  (iii) The Unadjusted Severance Payment shall not be reduced by
the amount of any other payment or the value of any benefit received or to be
received by Executive in connection with Executive's termination of employment
or contingent upon a change in control of the Company (whether payable pursuant
to the terms of this Agreement or any other agreement, plan or arrangement with
the Company or an Affiliate, predecessor or successor of the Company or any
person whose actions result in a change in control of the Company or an
Affiliate of such person) unless (1) in the opinion of tax counsel selected by
the Company's independent auditors and reasonably acceptable to Executive, such
other payments or benefit constitutes a "parachute payment" within the meaning
of Section 280G(b)(2) of the Code, and (2) in the opinion of such tax counsel,
the Unadjusted Severance Payment Plus all other payments or benefits which
constitute "parachute payments" within the meaning of Section 280G(b) (2) of the
Code would result in a portion of the Unadjusted Severance Payment being subject
to the excise tax under Section 4999 of the Code. In such event, the amount of
the Unadjusted Severance Payment shall be reduced by the minimum amount
necessary such that no portion thereof will be subject to the excise tax under
Section 4999 of the Code. The Unadjusted Severance Payment, as reduced, if at
all, pursuant to the provisions of this paragraph shall be referred to as the
Adjusted Severance Payment. In determining whether the Unadjusted Severance
Payment shall be reduced under this paragraph, (A) there shall not be included
in the computation any payment if Executive shall have effectively waived his
receipt or enjoyment of such payment or benefit, and (B) the value of any
non-cash benefit or any deferred cash payment shall be determined by the
Company's independent auditors in accordance with the principles of Sections
280G(d)(3) and (4) of the Code.

                  (iv) Except to the extent that the payment thereof would
subject any payment hereunder to the excise tax under Section 4999 of the Code:

                  (A) The Company shall also pay to Executive, as incurred, all
legal fees and expenses reasonably incurred by Executive as a result of the
termination of his employment (including all such fees and expenses, if any,
incurred in successfully contesting or disputing any such termination or in
seeking to obtain or enforce any right or benefit provided by this Agreement);
and

                  (B) For a thirty-six (36) month period after termination of
Executive's employment, the Company shall arrange to provide Executive with
life, accident and health insurance benefits substantially similar to those
which Executive was receiving or entitled to receive immediately prior to the
termination. Benefits otherwise receivable by Executive pursuant to this Section
5(a)(iv)(B) shall be reduced to the extent comparable benefits are actually
received by Executive during the thirty-six (36) month period following
Executive's termination, and any such benefits actually received by Executive
shall be reported to the Company.

                                        6

<PAGE>   7

                  (v) If it is established pursuant to a final determination of
a court or an Internal Revenue Service proceeding that, notwithstanding the good
faith of Executive and the Company in applying the terms of this Section 5(a),
the aggregate "parachute payments" paid to or for Executive's benefit are in an
amount that would result in any portion of such "parachute payments" being
subject to the excise tax under Section 4999 of the Code, then Executive shall
have an obligation to pay the Company upon demand an amount equal to the sum of
(1) the excess of the aggregate "parachute payments" paid to or for Executive's
benefit over the aggregate "parachute payments" that would have been paid to or
for Executive's benefit without any portion of such "parachute payments" being
subject to the excise tax under Section 4999 of the Code; and (2) interest on
the amount set forth in clause (1) of this sentence at the applicable federal
rate (as defined in Section 1274(d) of the Code) from the date of Executive's
receipt of such excess until the date of such payment.

                  (vi) Executive shall not be required to mitigate the amount of
any payment provided for in this Section 5 by seeking other employment or
otherwise nor shall the amount of any payment or benefit provided for in this
Section 5 be reduced by any compensation earned by Executive as the result of
employment by another employer or by retirement benefits after the date of
termination, or otherwise except as specifically provided in this Section 5.

                  (vii) The Company shall pay Executive the Unadjusted Severance
Payment in a lump sum no later than the fifth day following the date of
termination; provided, however, that if the Company in good faith believes that
the Unadjusted Severance Payment must be reduced under the provisions of Section
5(a)(iii) hereof, the Company shall pay to Executive at such time a good faith
estimate of the Adjusted Severance Payment (the "Estimated Adjusted Severance
Payment," the computation of which shall be given to Executive in writing
together with a written explanation of the basis for making such adjustment),
which amount shall in no event be less than 50% of the Unadjusted Severance
Payment. The Company shall, within sixty (60) days of the date of termination,
either pay to Executive the balance of the Unadjusted Severance Payment together
with interest thereon at the Applicable Federal Rate (as defined in Sections
1274(d) of the Code) or deliver to Executive a copy of the opinion of the tax
counsel referred to in Section 5(a)(iii) hereof establishing the amount of the
Adjusted Severance Payment. If the Adjusted Severance Payment exceeds the
Estimated Adjusted Severance Payment, the difference shall be paid to Executive
at such time together with interest thereon at the applicable federal rate (as
defined in Section 1274(d) of the Code).

                  (b) Definitions. For purposes of this Agreement, the following
terms shall be defined as follows:

                  (i) Change in Control. For purposes of this Agreement, a
"Change in Control" of the Company shall be deemed to have occurred if (A) any
"person" (as such term is used in Sections 13(d) and 14(d) of the Exchange Act,
but excluding the Company or any of its affiliates, a trustee or other fiduciary
holding securities under any employee benefit plan of the

                                        7

<PAGE>   8

Company or its affiliates, an underwriter temporarily holding securities
pursuant to an offering of securities or any company owned directly or
indirectly by the shareholders of Company in substantially the same proportion
as their ownership of Company) is or becomes the "beneficial owner" (as defined
in Rule 13d-3 under the Exchange Act), directly or indirectly, (other than where
such acquisition occurs in connection with a merger or consolidation where
immediately thereafter the pre-merger or pre-consolidation directors of the
Company continue to constitute at least a majority of the Board of Directors of
the surviving entity or any parent thereof) of securities of the Company
representing 25% or more of the combined voting power of the Company's then
outstanding securities, excluding securities acquired directly from the Company
or any of its affiliates; (B) during any period of two consecutive years (not
including any period prior to the execution of this Agreement), individuals who
at the beginning of such period constitute the Board and any new director, whose
election to the Board or nomination for election to the Board by the Company's
stockholders was approved by a vote of at least two- thirds (2/3) of the
directors then still in office who either were directors at the beginning of the
period or whose election or nomination for election was previously so approved,
cease for any reason to constitute a majority of the Board, provided that a
director whose initial assumption of office in connection with an actual or
threatened election contest would not be deemed an approved director for
purposes of determining whether approved directors have ceased to constitute a
majority of the Board; (C) the stockholders of the Company approve a merger or
consolidation of the Company with any other corporation, other than a merger or
consolidation where immediately thereafter the pre-merger or pre-consolidation
directors of the Company continue to constitute at least a majority of the Board
of Directors of the surviving entity or any parent thereof, or other than a
merger or consolidation effected to implement a recapitalization of the Company
(or similar transaction) in which no "person" (as herein above defined) is or
becomes the "beneficial owner" (as herein above defined) directly or indirectly,
of securities in the Company (excluding securities acquired by such person
directly from the Company or any of its affiliates), representing 25% or more of
the combined voting power of the Company's then outstanding securities; or (D)
the stockholders of the Company approve a plan of complete liquidation of the
Company or an agreement for the sale or disposition by the Company of all or
substantially all of the Company's assets.

                  (ii) Good Reason. For the purpose of this Agreement, "Good
Reason" shall mean the occurrence, without Executive's express written consent,
of any of the following circumstances unless, in the case of paragraphs (A),
(E), (F), (G), or (H), such circumstances are fully corrected prior to the date
of termination specified in the notice given in respect thereof:

                  (A) the assignment to Executive of any duties inconsistent
with his position as described in Section 1(b) of this Agreement, his removal
from such position, or a substantial diminution in the nature or status of
Executive's responsibilities from those in effect immediately prior to the
Change in Control;

                  (B) a reduction by the Company or any of its subsidiaries in
Executive's annual base salary as in effect on the date hereof or as the same
may be increased from time to time;

                                        8

<PAGE>   9

                  (C) the relocation of the office in which Executive is located
prior to the Change in Control to a location more than fifty (50) miles
therefrom or the Company or any of its subsidiaries requiring Executive to be
based anywhere other than the office in which Executive is located prior to the
Change in Control except for required travel on the business of the Company and
its subsidiaries to an extent substantially consistent with Executive's present
business travel obligations;

                  (D) the failure by the Company to pay to Executive any portion
of an installment of deferred compensation under any deferred compensation
program of the Company within seven (7) days of the date such compensation is
due;

                  (E) the failure by the Company or any of its subsidiaries to
continue in effect any compensation plan in which Executive participates prior
the Change in Control, unless an equitable arrangement (embodied in an ongoing
substitute or alternative plan) has been made in such plan in connection with
the Change in Control, or the failure by the Company or any of its subsidiaries
to continue Executive's participation therein on the same basis, both in terms
of the amount of benefits provided and the level of Executive's participation
relative to other participants, as existed at the time of the Change in Control;

                  (F) the failure by the Company or any of its subsidiaries to
continue to provide Executive with benefits at least as favorable as those
enjoyed by Executive under the employee benefit and welfare plans of the Company
and its subsidiaries, including, without limitation, the pension and profit
sharing, stock option, life insurance, medical, health and accident, disability,
deferred compensation and savings plans in which Executive was participating at
the time of the Change in Control, the taking of any action by the Company or
any of its subsidiaries which would directly or indirectly materially reduce any
of such benefits or deprive Executive of any material fringe benefit enjoyed by
him at the time of the Change in Control, or the failure by the Company or any
of its subsidiaries to provide Executive with the number of paid vacation days
to which he is entitled at the time of the Change in Control;

                  (G) the failure of the Company to obtain a satisfactory
agreement from any successor to assume and agree to perform this Agreement, as
contemplated in Section 6 hereof; or

                  (H) any purported termination of Executive's employment which
is not effected pursuant to a proper notice of termination satisfying the
requirements of this Agreement; for purposes of this Agreement, no such
purported termination shall be effective.

Executive's continued employment shall not constitute consent to, or a waiver of
rights with respect to, any circumstance constituting Good Reason hereunder. A
Change in Control of the Company shall not, by itself, constitute Good Reason.

                                        9

                  (c) No Duplication of Benefits. If Executive receives benefits
under this Section 5, he shall not be entitled to benefits under Section 4 of
the Agreement.

         6.       Assignment.

                  (a) 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 expressly
assume 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. Failure of the Company to obtain such assumption and agreement
prior to the effectiveness of any such succession shall be a breach of this
Agreement and shall entitle Executive to compensation from the Company in the
same amount and on the same terms as Executive would be entitled hereunder if
Executive had terminated his employment for Good Reason following a Change in
Control, except that for purposes of implementing the foregoing, the date on
which any such succession becomes effective shall be deemed the date of
termination. 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.

                  (b) This Agreement shall inure to the benefit of and be
enforceable by Executive's personal or legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees. If
Executive should die while any amount would still be payable to him hereunder if
Executive had continued to live, all such amounts, unless otherwise provided
herein, shall be paid in accordance with the terms of this Agreement to
Executive's devisee, legatee or other designee or, if there is no such designee,
to Executive's estate.

                  (c) This Agreement shall inure to the benefit of and shall be
enforceable by Company, its successors and assigns, and the rights and
obligations of this Agreement may not be delegated or assigned by Executive.

         7.       Confidential Information.

                  (a) Non-Disclosure. During the Employment Period or at any
time thereafter, irrespective of the time, manner or cause of the termination of
this Agreement, Executive will not directly or indirectly, reveal, divulge,
disclose or communicate to any person or entity other than authorized officers,
directors and employees of Company, in any manner whatsoever, any Confidential
Information (as hereinafter defined) of Company without the prior written
consent of the Board, except in connection with the fulfillment of his duties
hereunder.

                  (b) Definition. As used herein, "Confidential Information"
means information disclosed to or known by Executive as a direct or indirect
consequence of or through his association with Company and its subsidiaries,
about Company or any subsidiary of Company, their businesses, products and
practices, including but not limited to trade secrets, know-how, technical
information,

                                       10

<PAGE>   11

and financial information, which information is not generally known in the
business in which Company or any subsidiary of Company is or may become engaged.
However, Confidential Information shall not include any information which is (i)
available to the public from a source other than Executive, (ii) released in
writing by Company to the public or to persons who are not under a similar
obligation of confidentiality to Company and who are not parties to this
Agreement, (iii) obtained by Executive from a third party not under a similar
obligation of confidentiality to Company, or (iv) required to be disclosed by
any court process or any government or agency or department of any government.

                  (c) Return of Property. Upon termination of the Employment
Period, Executive will surrender to Company all Confidential Information,
including without limitation, all lists, charts, schedules, reports, financial
statements, books and records of Company and all subsidiaries of Company, and
all copies thereof, and all other property belonging to Company and all
subsidiaries of Company, provided that Executive shall be accorded reasonable
access to such materials subsequent thereto for any proper purpose as determined
in the reasonable judgment of Company.

         8. Agreement Not to Compete. It is recognized that in order to ensure
enforcement of the provisions of this Agreement related to confidential
information, that a limited covenant restricting competition is necessary.
Executive agrees that while he is employed by the Company and for a period of
one (1) year following the Date of Termination, neither he nor any affiliate
shall, either in his or its own behalf or as a partner, officer, director,
employee, agent or shareholder (other than as the holder of less than 5% of the
outstanding capital stock of any corporation with a class of equity security
registered under the Securities Exchange Act of 1934, as amended) engage in,
invest in. or render services to any person or entity engaged in the businesses
in which Company or any subsidiary of Company is then engaged and situated
within any country in which the Company or the particular subsidiary is so
engaged. Nothing contained in this Section 8 shall be construed as restricting
Executive's right to sell or otherwise dispose of any business or investments
owned or operated by Executive as of the date hereof. This provision shall not
prevent Executive's acceptance of employment with any business entity which is
diversified and made up of separate operations and which, as part of its
business, is not competitive with the Company or any subsidiary of the Company.
Further, this provision shall not prevent Executive's acceptance of employment
with another business entity during the Employment Period so long as such
employment is not in violation of this Section 8.

         9. Agreement Not to Solicit Clients and Employees. Executive agrees
that, for a period of two years following the Date of Termination of the
Employment Period, neither he nor any affiliate shall, on behalf of any business
engaged in a business competitive with Company or any subsidiary of Company,
solicit or induce, or in any manner attempt to solicit or induce, any person
employed by, or an agent of, Company or any subsidiary of Company to terminate
his employment or agency, as the case may be, with the Company or such
subsidiary.

         10. Assignment of Inventions. Executive agrees that he will assign to
Company or its appropriate subsidiary all inventions, discoveries and
improvements relating to its lines of business, conceived or made by him solely
or jointly with others during the Employment Period, and to execute, upon
request, whether during the Employment Period or thereafter, any and all
applications for patents, assignments and other papers which Company or its
counsel may deem necessary or appropriate for securing to it in all countries,
exclusive rights in all such inventions, discoveries and improvements.

         11. No Violation. Executive represents and warrants to Company that the
execution, delivery and performance of this Agreement by Executive does not,
with or without the giving of notice or the passage of time, or both, conflict
with, result in a default, right to accelerate or loss of rights under any
provision of any agreement or understanding to which Executive or his affiliates
are a party or by which Executive, or to the best knowledge of Executive,
Executive's affiliates may be bound or affected.

         12. Captions. The captions, headings and arrangements used in this
Agreement are for convenience only and do not in any way affect, limit or
amplify the provisions hereof.

         13. Notices. All notices required or permitted to be given hereunder
shall be in writing and shall be deemed delivered when actually received or, if
mailed, whether or not actually received, two days after deposited in the United
States mail, postage prepaid, registered or certified mail, return receipt
requested, addressed to the party to whom notice is being given at the specified

be illegal, invalid or unenforceable under present or future laws, the remaining
provisions of this Agreement shall remain in full force and effect and shall not

         16. Waiver. No delay or omission by either party hereto to exercise any
right or power hereunder shall impair such right or power or be construed as a
waiver thereof. A waiver by either of the parties hereto of any of the covenants
to be performed by the other or of any breach thereof shall not be construed to
be a waiver of any succeeding breach thereof or of any other covenant herein
contained. All remedies provided for in this Agreement shall be cumulative and
in addition to and not in lieu of any other remedies available to either party
at law, in equity or otherwise.

         17. Counterparts. This Agreement may be executed in multiple

together shall constitute one and the same agreement.

according to the laws of the State of Wisconsin.

Agreement as of the date first above written.
