                              RESIGNATION AGREEMENT

         This Resignation Agreement ("Agreement") is by and among Joseph M.
Konradt ("you" or the "Executive"), First Federal Savings Bank LaCrosse-Madison
("we," "us" or the "Bank") and First Federal Capital Corp. (the "Company").

                                   BACKGROUND

         Your active employment with us ended effective as of February 4, 2003
(the "Resignation Date"). We will provide you with certain payments and other
benefits for a period of time after your Resignation Date in accordance with the
terms of this Agreement (which is intended to reflect and replace the Employment
Agreement as it was in effect between yourself and the Bank up until your
Resignation Date).

                               TERMS OF AGREEMENT

         The Executive, the Bank and the Company agree to the following terms:

         1.    SEVERANCE AND OTHER PAYMENTS AND BENEFITS. You will receive
certain severance payments and other benefits provided pursuant to Section 5(vi)
of your Employment Agreement with the Bank and as described in the attached
"Benefits Summary" (which is incorporated herein and made a part hereof by
reference). The Benefits Summary sets forth all amounts, payments and benefits
of any type whatsoever to be received by you from us and contains important
information about the terms and conditions for these benefits. Please read the
Benefits Summary closely.

         2.    LAW WHICH APPLIES TO THIS AGREEMENT. This Agreement will be
interpreted and enforced based on the laws of the State of Wisconsin.

         3.    RELEASE OF CLAIMS.

               a) Your Release. In exchange for the payments and other benefits
specified in this Agreement, you -- for yourself, your spouse, your heirs and
all other representatives -- agree to give up (waive) all claims of any nature
whatsoever, contractual or otherwise, which you may have relating to your
employment, or the termination of your employment, with us. This waiver of
claims applies to all claims against the Bank and the Company or any company
owned by or otherwise related to the Bank or the Company (including all
predecessors, successors and assigns), as well as to anyone associated with or
representing us in the past or present, such as officers, directors, employees
and agents.

               The claims you are waiving include but are not limited to claims
under Federal, state or local law for discrimination, breach of contract, lost
wages, compensatory damages, punitive damages, attorneys' fees and all other
claims of any type or nature, whether known or unknown, matured or unmatured,
direct or indirect. You also agree not to start any lawsuits or other actions,
and not to make any other claims in state or Federal court, or with any state,
Federal or local governmental, administrative or advisory agency for any purpose
related in any way to your employment with us or the termination of your
employment.

<PAGE>
               You acknowledge that we have agreed to provide the payments
and benefits described in this Agreement subject to your execution of this
Agreement and that you give up any claims you may have against us. BY SIGNING
THIS AGREEMENT, YOU ARE GIVING UP ALL CLAIMS WHICH YOU MAY HAVE AGAINST THE
BANK, THE COMPANY AND ANY RELATED PERSON OR ENTITY, EXCEPT FOR YOUR RIGHT TO
ENFORCE RECEIPT OF THE BENEFITS AND PAYMENTS DESCRIBED HEREIN.

               b) Our Release. The Bank and Company -- for themselves, their
affiliates, successors and assigns -- agree to give up (waive) all claims of any
nature whatsoever which they may have relating to your employment or the
termination of your employment with us; provided, however, that this release
shall not extend to any claim based upon any fraudulent or dishonest act
committed by you against us. This waiver of claims applies to claims by the Bank
or Company against your spouse, heirs and other representatives, as well as
against yourself.

         4.    OFFICER INDEMNIFICATION AND RESIGNATION. Notwithstanding your
release of claims outlined above, this release does not apply to your right as a
former officer and director to indemnification from us or our insurer for claims
brought by third parties based on any acts or omissions by you within the scope
and during the term of your employment, subject to the limits and conditions
imposed by applicable laws and regulations, and by our by-laws and other
policies relating to indemnification of officers and directors generally. You
agree that execution of the Agreement also evidences your resignation from your
positions as an officer and director of First Reinsurance, Inc. and as a
director of F.F. Mortgage Reinsurance, Inc., each effective as of the date of
termination of your employment with us.

         5.    WAIVER OF AGE DISCRIMINATION CLAIMS; REVIEW AND CANCELLATION. In
exchange for the amounts to be paid to you by us under this Agreement, you
specifically waive any claims which you have or may have against the Bank, the
Company or any related person or entity under the Age Discrimination in
Employment Act of 1967, the Older Workers Benefit Protection Act or any other
similar law. You will have up to 21 days from the receipt of this Agreement to
review and decide whether to accept it. You will also have a period of 7 days
after signing this Agreement (the "Cancellation Period") in which to cancel it
and this Agreement will not become effective until this time period has passed.

You acknowledge that the payments and benefits provided to you include an
additional $2,500 included in the amounts described in the Benefits Summary.
This additional amount is not otherwise owed to you by the Bank or Company and
will be paid specifically as consideration for your waiver of age discrimination
claims.

         6.    AVAILABILITY OF OUTPLACEMENT SERVICES. The Bank and Company agree
that you may, subject to prior consultation with the Bank and receipt of Bank
approval (which approval shall not be unreasonably withheld) retain an executive
outplacement service (the "Service") for the purpose of assisting you in meeting
your "duty to mitigate" under Section 7 below. The Bank agrees that it will
assist you in deferring the cost of retaining outplacement services by making
payment directly to the Service of up to the first Thirty Thousand Dollars
($30,000.00) of expense incurred.

                                      -2-

<PAGE>
         7.    ACKNOWLEDGMENT OF DUTY TO MITIGATE. You agree that you have an
ongoing obligation to seek an executive level position with an annual salary
exclusive of bonuses of not less than $175,000; provided, however, that you are
not required to accept a position outside of a 25 mile radius of LaCrosse,
Wisconsin. It is agreed that the Bank and Company will waive your duty to
mitigate if you pursue additional college or university level education for the
purpose of enhancing or altering your career opportunities; provided, however,
that in such event the Bank may offset any amounts paid to the Service against
the final two (2) payments under Section 1 of the Benefits Summary, but only to
the extent you have not received mitigation income and benefits sufficient to
offset the amount of the Bank's payments to the Service for your benefit. The
Bank and Company will also waive your duty of mitigation in the event of
disability. [For purposes of this Agreement, the term "disability" shall mean
your inability, as a result of physical or mental incapacity, to substantially
perform for a period of 180 consecutive days the duties required of an executive
level position. Any questions as to the existence of your disability upon which
you and the Bank cannot agree shall be determined by a qualified independent
physician mutually agreeable to you and the Bank or, if the parties are unable
to agree upon a physician within ten (10) days after notice from either to the
other suggesting a physician, by a physician designated by the then president of
the medical society for the county in which you maintain your principal
residence, upon the request of either party. The costs of any such medical
examination shall be borne by the Bank.] If you do obtain employment, you agree
to advise Mr. Mel Duncan at the Bank, with the compensation and benefits
received from such employment then being treated as an offset to amounts
otherwise remaining to be paid hereunder.

         8.    NONDISCLOSURE OF AGREEMENT TERMS; NO DEROGATORY COMMENTS;
DISCONTINUANCE OF USE OF IMAGE. You agree not to disclose any of the terms of
this Agreement to any other person or entity except for your legal, tax and
other advisors consulted in connection with review of this Agreement, and your
family members; and you will assure that all advisors and family members do not
disclose the terms of this Agreement to any other person or entity. The Bank and
Company will not disclose the terms hereof, except to the extent required by
disclosure requirements imposed by the Securities Exchange Act of 1934. You and
the Bank and Company each also agree not to make any derogatory comments about
the other (or, with respect to the Bank and the Company about our respective
employees or agents). Executive agrees not to object to post-Resignation use of
his name and image for promotional purposes, provided that the Bank and Company
discontinue such use no later than August 31, 2003.

         9. CONFIDENTIAL INFORMATION. You acknowledge that during the course of
your employment with us, you have produced and have had access to materials,
records, data, trade secrets and information not generally available to the
public regarding us and related entities (collectively the "Confidential
Information"). You agree to keep all Confidential Information in confidence, and
that you will not directly or indirectly disclose, use, copy, make lists or
otherwise utilize any such Confidential Information, except as specifically
authorized by us or required by any court or administrative agency. Confidential
Information does not include any information which is already known generally to
the public. This prohibition is not intended to extend to or prohibit your use
of general skills and know-how acquired during your employment with us and we
specifically consent to your use and publication of management style, technique
and motivation information, materials, etc. which do not contain information
specific to the business of the Bank or Company in connection with any such
publication (including no

                                      -3-
<PAGE>
objection by the Bank to your use of the name "Carpe Occasio" and which use or
publication on your part will not prevent continued usage by the Bank). All
records, files, documents and other materials which you have prepared, used or
come into contact with shall remain our property, and to the extent you have
made copies of such materials (or otherwise retained such materials where they
are not necessary to Bank or Company operations) you will not use such
information in any manner detrimental to the Bank or Company.

         10.   REVIEW BY AN ATTORNEY. You are encouraged to have this Agreement
reviewed, at your expense, by an attorney of your choice. By signing this
Agreement, you acknowledge that you have had enough time to have an attorney
review this Agreement.

         11.   PRIOR AGREEMENTS NOT ENFORCEABLE. This Agreement contains the
entire agreement of the parties regarding this matter. Any prior
representations, promises or agreements (whether oral or written) which are not
in this Agreement or the attached Benefits Summary are hereby superseded and not
enforceable. The terms of this Agreement may not be altered, amended or waived
except by another written agreement signed by all parties.

         12.   EXPENSES OF ENFORCEMENT. If any legal proceeding is necessary to
enforce or interpret this Agreement, or to recover damages for breach of it, the
prevailing party, shall be entitled to recover from the other party reasonable
attorneys' fees and necessary costs and disbursements incurred in such
litigation, in addition to any other relief to which such prevailing party may
be entitled.

         13.   UNDERSTANDING OF TERMS. You and we each acknowledge that we have
read this Agreement completely, and fully understand the terms, nature and
effect of this Agreement, and that we each execute it voluntarily and in good
faith.

         14.   SUCCESSORS; BINDING AGREEMENT. This Agreement will be binding on
the parties hereto and on their respective successors, heirs, and assigns,
including with respect to the Bank or Company 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 Bank or Company. Any
successor to the Bank or Company shall be bound to expressly assume and agree to
perform this Agreement in the same manner and to the same extent that the Bank
or the Company would be required to perform it if no such succession had taken
place.

         15.   COUNTERPARTS. Duplicate copies of this Agreement may be signed,
and each copy will be considered an original document, but when taken together,
all copies will constitute one Agreement.

                                BENEFITS SUMMARY

         The following is a summary of benefits ("Summary") to be provided to
Joseph M. Konradt ("Executive") by First Federal Savings Bank LaCrosse-Madison,
F.S.B. (the "Bank") and First Federal Capital Corp. (the "Company") under and
pursuant to your Resignation Agreement bearing even date herewith:

1.       Severance Payments.

               Severance payments for a period of thirty-six (36) months
(beginning as of February 5, 2003 and ending February 4, 2006 -- the "Severance
Pay Period") based on a Base Salary of $236,500.00, and a cash bonus payment of
$114,069.00 for the calendar year ended December 31, 2002, payable at the rate
of $29,214.08 per month during the Severance Pay Period in accordance with the
Bank and Company's normal payroll practices. The first such payment will be made
on the first normal payroll date following your Resignation Date; provided that
the Bank will suspend payments after the February 28, 2003 pay date if (i) the
Resignation Agreement has not been executed by said date, or (ii) at anytime the
executed Resignation Agreement is cancelled prior to expiration of the
Cancellation Period. All payments made after your Resignation Date will count as
payments made for purposes of the Severance Pay Period. The Bank's payment
obligation shall terminate in the event of your death; provided, however, in the
event of Disability the Bank and Company shall continue payments for the balance
of the Severance Pay Period (offset by any disability payments actually received
by you from disability plans or insurance maintained or provided by the Bank and
by disability payments from any Social Security or other governmental plan or
program) at a monthly rate of $19,708 (i.e. Base Salary without consideration of
bonus). All severance payments provided pursuant to this Section shall be offset
by any compensation received by Executive from employment during the Severance
Pay Period.

2.       Waiver of Age Claims Payment.

               You will receive an additional payment of $2,500, included in
the first severance payment made to you by the Bank following expiration of the
Cancellation Period. This is an additional payment not otherwise owed to you by
the Bank or Company and which is paid specifically as consideration for your
waiver of age discrimination claims pursuant to Section 5 of the Resignation
Agreement.

3.       Group Insurance Coverages.

               The Bank and Company will maintain for Executive, on the same
basis (including any required employee premium contribution) as made available
to active employees of the Bank, continued coverage under the Bank's group
insurance programs (i.e. health, dental, group life, dependent life, personal
accident insurance and group long-term disability insurance) for the thirty-six
(36) month period for which resignation payments are made; provided, that
coverage under the Bank's group programs will end at such earlier time as
Executive may obtain employment which provides him with coverage under
comparable programs of another employer. If Executive fails to obtain employment
providing comparable coverages prior to expiration of such thirty-six (36) month
period, Executive may continue coverage under the

<PAGE>

Bank or Company's group health and dental insurance programs for up to an
additional eighteen (18) months at his expense as calculated by the Bank or
Company.

               In addition to group life insurance coverage, the Bank or
Company has paid the 2003 premium on a $150,000 face value insurance policy on
Executive's life and will also pay the premiums as they come due for such policy
in 2004 and 2005, after which the Bank will transfer the policy to Executive.

               The Bank or Company has also paid the 2003 premium on an
executive disability policy and will also pay the premiums as they come due for
such policy in 2004 and 2005, after which the policy shall become Executive'
responsibility to continue if he so chooses (any amounts received by Executive
under said disability policy will be credited for disability obligation offset
purposes against the Bank's obligations under Section 1 above).

4.       Qualified Retirement Plans.

               Executive is fully vested in benefits accrued through the
Resignation Date under the qualified retirement plans maintained by the Bank and
by First Federal Capital Corp. (i.e. the First Federal Savings Bank Savings
Investment Plan or "401(k) Plan", the First Federal Capital Corp. Employee Stock
Ownership Plan or "ESOP", and the First Federal Savings Bank La Crosse-Madison
Pension Plan or "Pension Plan"). Executive shall be entitled to receive his
vested benefits under each of said plans in accordance with the respective terms
of such plans. Your accrued benefits and balances under each of the qualified
plans are as follows:

               (i)   Pension Plan -- An accrued monthly benefit of $3,626.00
         per month, with payments to commence at your age 65 (October 1, 2021)
         as a life annuity with 120 monthly payments certain (computed through
         February 4, 2003).

               (ii)  401(k) Plan-- An account balance of $206,917 as of
         December 31, 2002.

               (iii) ESOP -- An account balance of $360,228.00 as of December
         31, 2002.

         The monthly benefit under the Pension Plan is fixed, while the other
         account balances will increase or decrease based on investment
         performance since December 31, 2002.

               In addition, Executive shall be credited with service and
accrual under each of the qualified plans equivalent to that which he would have
received during the thirty-six (36) month period following his Resignation Date
if he had continued as an employee of the Bank (and based on the amount of
compensation received by Executive during the Severance Pay Period, but not in
excess of the level of compensation permitted to be considered for qualified
plan purposes). Such equivalent treatment shall entitle Executive to an amount
equivalent to a matching contribution of 3% of compensation under the 401(k)
Plan, to the equivalent of a contribution to the ESOP of 1.5% of compensation,
and to the equivalent of additional accrued Pension Plan credit (actuarially
adjusted) for the 36-month Severance Pay Period. The equivalent amounts that
Executive would have earned or had credited to his account under each of the
qualified plans would have been as follows:

<PAGE>
               (i)   Pension Plan -- An additional monthly benefit having a
         current equivalent value for lump-sum distribution purposes of
         $28,021.00.

               (ii)  401(k) Plan-- Additional account contributions of
         $18,000.00.

               (iii) ESOP-- Additional account contributions of $9,000.00.

               Such amounts shall be paid by the Bank to Executive as a lump
         sum within sixty (60) days of expiration of the Cancellation Period.

5.       Stock Options.

               You will have until August 4, 2003 to exercise your 51,400
outstanding and vested stock options. No further vesting of options or of
restricted stock awards will occur subsequent to the Resignation Date.

6.       Incentive Programs.

               There will be no accruals nor participation by Executive under
any Bank or Company incentive or Supplemental Nonqualified Retirement Program
(the "SERP") following the Resignation Date, except to the extent the Severance
Payments provided pursuant to Section 1 above reflect the bonus amount received
by Executive for the calendar year ended December 31, 2002.

               Executive has an accrued and vested SERP benefit which
consists of amounts calculated with respect to each of the 401(k) Plan, ESOP,
and Pension Plan. The Bank has calculated the present value of each of those
respective elements of the SERP benefit as of your Resignation Date (including
an actuarially adjusted payment for the Pension Plan portion) as follows:

               (i)   Pension Plan -- An additional monthly benefit amount of
         $1,327 per month (having a current equivalent lump-sum distribution
         value of $74,057.00).

               (ii)  401(k) Plan-- Additional account contributions of
         $10,901.00.

               (iii) ESOP-- Additional account contributions of $9,672.00.

               The Pension Plan lump sum amount is fixed, while the other
         account balances will increase or decrease based on investment
         performance since December 31, 2002.

               The actual present value amounts will be paid to Executive in
         the form of a lump sum payment within sixty (60) days of expiration of
         the Cancellation Period.

7.       Outplacement Costs. Subject to approval of Executive's selection of a
Service pursuant to Section 6 of the Resignation Agreement, the Bank and Company
shall pay directly to such Service the first Thirty Thousand Dollars
($30,000.00) of costs related to Executive's effort to obtain employment. If
Executive returns to school to enhance his career opportunities during the
Severance Pay Period, the Bank will offset costs paid to the Service against the
final two (2)
<PAGE>

monthly severance payments due under Section 1 hereof, but only to the extent
Executive has not received mitigation income and benefits sufficient to offset
the amount of the Bank's payments to the Service for Executive's benefit.

8.       PTO Benefit.

               The amount of PTO benefit attributable to employment prior to
(accrued vacation, sick-pay, etc.) will be included in the first payment to
Executive following expiration of the Cancellation Period. There will be no PTO
accruals during or attributable to the Severance Pay Period.

9.       Company Car.

               The Bank agrees to transfer title to the vehicle it currently
makes available for Executive's use to Executive without charge, valuing the
same at $21,000.

10.      La Crosse Country Club. Executive will be forgiven his obligation for
repayment to the Bank or Company of the amount advanced by the Bank on his
behalf for the acquisition of Capital Membership Certificates and Initiation
Fees for his membership at the La Crosse Country Club, as well as for club dues
paid through December 31, 2003.

11.      Taxes.

               Generally, the Bank will deduct from any payments made to you
under this Agreement any Federal, state or local withholding (including FICA),
income or other taxes which it believes are required to be deducted from time to
time under applicable law. All amounts payable to you are stated in this
Agreement before any such deductions have been made. You will be responsible for
talking to your own advisors to determine the effect of payments on your tax
liability, social security payments and other rights and obligations.

12.      Changes to Plans or Policies.

               The terms, conditions and provisions of the Bank's insurance
plans and policies may be changed from time to time, up to and including
termination of any plan or policy. The Bank may make these changes without
notifying you and without your approval; provided the group coverages provided
shall not be less than the group coverages generally provided to the Bank's
executive employees. The Bank will provide you information about your benefits
that is provided to other employees for utilization of such benefits. Any change
in the Bank's plans or policies may change the type or cost of medical insurance
or other benefits which you receive.

13.      Stonier Graduate School of Banking.

               Executive will be forgiven any obligation for repayment of
tuition expenses incurred by the Bank on his behalf for his enrollment at the
Stonier Graduate School of Banking.

                                    within the Financial Statements, other than

                           (ii)     The parties hereto acknowledge that the
                                    Liabilities reflected on the Seller's
                                    January 31, 2002 balance sheet may contain
                                    some estimates, but the actual amounts will
                                    not vary materially from the estimates. If
                                    the Seller identifies any of the amounts of
                                    the Liabilities described in clause (i) as
                                    estimated due only to the absence of final

                                    Agreement, the Buyer and Seller in good
                                    faith will endeavor to agree on and
                                    substitute the actual amount of such
                                    Liability (provided that the actual amount
                                    of such Liability was incurred in the
                                    Ordinary Course and is not materially
                                    different than the estimates) for the
                                    estimated amount reflected on the January
                                    31, 2002 balance sheet,

                                    amount of such Liability instead of the
                                    estimated amount;

                           (iii)    Any executory Liability to the Seller's
                                    customers incurred by the Seller in the

                           payable to the Seller, within 45 days of the Buyer's
                           receipt of an audited financial statement for the
                           Business for its fiscal year ending December 31,
                           2005, equal to (i) eighty-nine and three-tenths
                           percent (89.3%) of twenty percent (20%) of the
                           Business Equity Value of the Buyer as determined by
                           the Buyer's independent certified public accountants,
                           less (ii) those amounts specified or described in
                           Section 10.6 hereof and/or any other amounts properly
                           offset against the Contingent Amount in accordance
                           with this Agreement. "BUSINESS EQUITY VALUE" shall
                           mean an amount equal to the product of five (5) times
                           the weighted average Adjusted EBITDA of the Business
                           for its fiscal years ending December 31, 2003, 2004
                           and 2005, weighting 2003 Adjusted EBITDA by a factor
                           of one (1), weighting 2004 Adjusted EBITDA by a
                           factor of four (4), weighting the 2005 Adjusted
                           EBITDA by a factor of five (5), and dividing the
                           resulting sum by a factor of ten (10). "ADJUSTED
                           EBITDA" shall mean the separate earnings of the
                           Business as conducted by the Buyer computed before
                           interest, income taxes, depreciation and
                           amortization, as reflected on an income statement of
                           the Buyer, adjusted to: (i) eliminate the effect of
                           (A) extraordinary or non-recurring items of gain
                           (such as the gain or sale of disposed capital assets
                           or insurance proceeds) and (B) receipt of indemnity
                           payments, if any, received by the Buyer in connection
                           with this Agreement and the transactions contemplated
                           hereby, and (ii) reflect reasonable charges (as
                           determined by such independent certified public
                           accountants) for services (e.g., corporate services

                           Inc. to the Buyer. The Buyer shall cause its
                           independent certified public accountants to provide
                           the Seller, reasonably promptly after the end of each
                           calendar year and the

                           completion of the financial statements for such year,
                           commencing with calendar year 2002, with such
                           accountant's calculation of such year's Adjusted
                           EBITDA. The Seller shall have a period of 30 days
                           after receipt thereof to confirm such calculation as
                           being made correctly in accordance with this Section
                           2.1(c) or issue an objection thereto. If the Seller
                           fails to object to such calculation within such
                           30-day period, the calculation shall be conclusive
                           and final. If the Seller objects within such 30-day
                           period, the Seller shall specify its objection in
                           writing, detailing the portion(s) of such calculation
                           which the Seller believes has not been made in
                           accordance with this Section 2.1(c), and supplying
                           such information as the Seller possesses to support
                           its objection. If, within 20 days after receipt of
                           such objection, the Buyer and Seller have not
                           resolved their differences, the parties shall submit
                           such differences (to the extent not reconciled during
                           such 20-day period) to arbitration pursuant to
                           Section 11.5 of this Agreement.

                           In the event that the Buyer disposes of the Business
                           prior to December 31, 2005 (which the Buyer covenants
                           that it shall not do, unless (i) the Buyer pays any
                           Contingent Amount due the Seller in accordance
                           herewith simultaneously with the closing of such
                           disposition, or (ii) if such Contingent Amount is not
                           so simultaneously paid, the acquiror thereof agrees
                           expressly to assume the obligation herein contained
                           to pay the Contingent Amount in accordance with its
                           terms, or (iii) the Seller expressly agrees in
                           writing to such disposition), Adjusted EBITDA will be
                           determined by utilizing the weighted average Adjusted
                           EBITDA of the Business for the three (3) completed
                           fiscal years of the Buyer immediately preceding the
                           year of such disposition, weighting such years'
                           Adjusted EBITDA in a similar manner as set forth
                           above, and the contingent Amount, as so determined,
                           will be paid by the Buyer simultaneously with the
                           closing of such disposition. If the Business is
                           disposed of at a time such that the Buyer has not
                           completed three (3) fiscal years' conduct of the
                           Business, weighted average Adjusted EBITDA shall be
                           based upon the actual number of completed fiscal
                           years which the Buyer has conducted the Business
                           preceding the disposition. In such event: if the
                           number of such completed fiscal years is two (2), the
                           Adjusted EBITDA for the fiscal year immediately
                           preceding the year of the Business's disposition
                           shall be weighted by a factor of six (6) and the next
                           preceding fiscal year's Adjusted EBITDA shall be
                           weighted by a factor of four (4), and the resulting
                           sum shall be divided by a factor of ten (10); if the
                           number of such completed fiscal years is one (1), the
                           Business Value will be determined based upon the
                           product of five (5) times such year's Adjusted EBITDA
                           and no weighting shall be required.

         2.2      Mateski Properties Purchase Price. The full consideration
payable to Mateski Properties for the Mateski Properties Purchased Assets (the
"MATESKI PROPERTIES PURCHASE PRICE") shall be the Buyer's assumption at the
Closing of, and agreement to discharge, the following (and only the following)
obligations of Mateski Properties (the "ASSUMED MATESKI PROPERTIES
OBLIGATIONS"):

                           balance sheet may contain some estimates, but that
                           the actual amounts will not vary materially from the
                           estimates. If Mateski Properties identifies any of
                           the Liabilities described in Section 2.2(a) as
                           estimated due only to the absence of final
                           information as of the date of this Agreement, the

                           endeavor to agree on and substitute the actual amount
                           of such Liability (provided that the actual amount of
                           such Liability was incurred in the Ordinary Course
                           and is not materially different than the estimates)
                           for the estimated amount reflected on the January 31
                           balance sheet, and the Buyer shall then assume such
                           actual amount of such Liability instead of the
                           estimated amount; and

         3.1      Non-Assumption of Liabilities. Except only as provided in
Sections 2.1(b) and 2.2 hereof, the Buyer shall not assume, pay, perform,
discharge, or accept any liabilities, debts or obligations of the Seller,
Mateski Properties, Shareholders or Members of any kind whatsoever, whether
actual, contingent, accrued, known or unknown, including, without limitation,
any of the following:

                           (i)      Any Liability arising out of or related to

                                    manufactured or sold prior to the Closing
                                    other than to the extent assumed under
                                    Sections 2.1(b)(iii), (iv) or (v);

                           (ii)     Any Liability under a Contact assumed by the

                                    arises after the Closing but that arises out

<PAGE>

forfeitures, chargebacks or penalties which have been or will be incurred due to
the failure of the Seller to complete the work-in-progress in a timely manner.

with all requirements of Law and with all agreements to which the Seller or
Mateski Properties is a party. The policies evidencing the Insurance are valid,
outstanding and enforceable policies subject to the terms and conditions
contained therein, and there has not occurred any act or omission of the Seller

by this Agreement.

                  (b)      Denials of Coverage. Neither the Seller nor Mateski
Properties has been refused any insurance with respect to the Business, Purchase
Assets or Mateski Properties Purchased Assets, nor has the dollar amount of any
coverage that has been previously in effect or requested by Seller or Mateski

Properties are in compliance with the terms and conditions of all such Licenses.

state of facts exists which, with the giving of notice on the passing of time,
or both, may give rise to any Breach under any such License or permit the
Seller, Mateski Properties or other parties to any such License to declare a
Breach of, or otherwise cancel or terminate, any such License. Except as set

and the Seller and the Seller's 401(k) Plan shall remain solely and entirely
responsible for satisfying any and all obligations and liabilities arising under
the Seller's 401(k) Plan. The accrued benefits under the Seller's 401(k) Plan of
all Hired Employees shall become 100% vested and non-forfeitable as of the
Closing Date to the extent not already 100% vested and non-forfeitable and the
Seller shall cause the Seller's 401(k) Plan to be amended, if necessary, to
provide for such 100% vesting and nonforfeitability. The accrued benefits of the
Hired Employees under the Seller's 401(k) Plan shall be distributed to the Hired
Employees after the Closing Date in accordance with the terms of the Seller's
401(k) Plan and the applicable provisions of the Code.

         6.21     Confidentiality; Noncompetition.

                  (a)      Confidential Information. The Seller, Mateski
Properties, Shareholders and Members acknowledge that they possess information
of a confidential nature relating, inter alia, to the operations, finances,
business relationships and trade secrets of the Business and agree that, for a
period of five (5) years following the Closing Date, other than as required in
the course of their employment with the Buyer, none of them directly or
indirectly shall use, publish, disclose or authorize anyone else to use, publish
or disclose, without the prior written consent of the Buyer, within the
geographical area in which such use, publication or disclosure could harm the
Business, any confidential information pertaining to the Business, including,
without limitation, any information relating to existing or potential business,
customers, suppliers, trade or industrial practices, finances, plans, costs,
processes, product formulae, technical or engineering data, or trade secrets;
provided, however, that the Seller, Mateski Properties, Shareholders and Members
shall be prohibited from ever using, publishing, disclosing or authorizing
anyone else to use, publish or disclose, any confidential information which
constitutes a trade secret under applicable law. However, such restrictions
shall not apply to any information which is generally known to the public
through no fault of the Seller, Mateski Properties, Shareholders or Members or
which is required by Law to be disclosed (provided, however, that before any
such disclosure required to be made by Law, the disclosing Person shall inform
the Buyer thereof, and shall cooperate with the Buyer in obtaining a protective,
limiting or similar order restricting the scope or dissemination of such
disclosed information).

                  (b)      Noncompetition. For a five (5) year period following
the Closing Date, none of the Seller, Mateski Properties, Shareholders or
Members directly or indirectly (through Related Persons or otherwise) shall: (i)
engage, as an employee, officer, director, partner, consultant, owner (other
than a minority shareholder interest of not more than 1% of a company whose
equity interests are publicly traded on a nationally recognized stock exchange
or over-the-counter), financier or in any other capacity, or assist any other
person, firm or entity to engage in any activity (A) competitive to the Business
as such Business is conducted on the Closing Date or as planned by the Seller to
be conducted within one year of the Closing Date, in any

                                       36

<PAGE>

geographic area in which the Seller conducts the Business or promotes its
products and services or in any geographic area wherein the Seller has made
plans to enter within one year from the Closing Date; or (ii) solicit or accept
the competitive business of any person, firm or entity which is or was a
customer of the Business or of any prospective customer to whom the Seller made
any proposal, sales effort or solicitation since January 1, 1999, with respect
to products or services which compete with the Business.

                  (c)      Non-Solicitation. For a period of five (5) years
following the Closing Date, none of the Seller, Mateski Properties, Shareholders
or Members shall directly or indirectly: (i) solicit, or assist another person,
firm or entity to solicit, any employee, supplier or other person having
business relations with the Business to terminate such employee's employment or
terminate or curtail such supplier's or other Person's relationship with the
Business; or (ii) hire, employ or retain, or solicit or assist another Person,
firm or entity to hire, employ or retain, any employee of the Business.

                  (d)      Referral. For a period of five (5) years following
the Closing Date, if the Seller, Mateski Properties, Shareholders or Members
receives any request or inquiry to provide the types of products and services of
the type provided by the Business, such Person will promptly refer such request
or inquiry to the Buyer. In no event shall the Seller, Mateski Properties,
Shareholders or Members disparage the Buyer or the Business's reputation.

                  (e)      Agreement on Fairness. The Seller, Mateski
Properties, Shareholders and Members acknowledge that, with respect to the
reasonableness of this noncompetition covenant: (i) in determining the
consideration paid to the Seller and Mateski Properties for the Purchased
Assets, Mateski Properties Purchased Assets and Business, the Buyer has valued
the Purchased Assets, Mateski Properties Purchased Assets and Business in
reliance upon the goodwill and earnings stream reasonably expected to be derived
therefrom and, further, upon the absence of activities by the Seller, Mateski
Properties, Shareholders and Members competitive to the Business and the absence
of disclosure by such Persons of confidential information, which reliance and
reasonable expectations would be unfairly frustrated if the Seller, Mateski
Properties, Shareholders or Members failed to comply with the restrictions
contained herein; (ii) the covenants contained in this Section 6.21 have been
specifically bargained between the parties in the context of the contemplated
transactions; (iii) the Seller, Mateski Properties, Shareholders and Members
have obtained legal counsel to review this Agreement; (iv) the covenants made by
and duties imposed upon them hereby are fair, reasonable and minimally necessary
to protect the legitimate business interests and expectations of the Buyer, and
such covenants and duties will not place an undue burden upon the Shareholders
or Members in the event of the strict enforcement of the covenants contained
herein; and (v) the economic benefits of the contemplated transactions directly
and indirectly accruing to the Seller, Mateski Properties, Shareholders and
Members constitute full, fair and adequate consideration to them in exchange for
their execution of and compliance with this Agreement.

                  (f)      Equitable Relief. The Seller, Mateski Properties,
Shareholders and Members acknowledge that any Breach of this Section 6.21 will
cause substantial and irreparable harm to the Buyer for which money damages
would be an inadequate remedy. Accordingly, in addition to any other rights or
remedies available at law, in equity or by statute, the Buyer shall in any such
event be entitled, without the necessity of posting bond or other assurance, to
obtain injunctive and other forms of equitable relief to prevent such Breach.

                                       37

<PAGE>

                  (g)      Joint and Several Obligations. The covenants and
representations of the Seller, Mateski Properties, Shareholders and Members
contained in this Section 6.21 shall be their joint and several obligations.

                  (h)      Extension of Time Periods. In the event of a Breach
by the Seller, Mateski Properties, Shareholders or Members of any covenant set
forth in this Section 6.21, the duration of such covenant shall be extended by
the period of the duration of such Breach.

                  (i)      Severability; Blue-Pencil. Each of the covenants
contained herein is independent and divisible. If any arbitrator or court of
competent jurisdiction determines that any particular provision of this
Agreement is invalid or unenforceable, then such invalidity or unenforceability
shall have no effect on the other provisions hereof, which shall remain valid,
binding and enforceable and in full force and effect. If any provision of this
Agreement is held to be invalid or unenforceable due to an excessively broad
duration, activity or subject, such provision shall be construed by limiting or
reducing it to such duration or scope as will render the remaining provision, as
so construed, valid and enforceable.

         6.22     Termination of Lease. Mateski Properties and the Seller shall
have executed, and at the Closing delivered a counterpart thereof to the Buyer,
a termination of that certain Lease, dated April 1, 2000 by and between them,
effective as of the Closing, and on terms acceptable to the Buyer (including,
without limitation, a complete release by Mateski Properties in favor of the
Seller with respect to any and all obligations of the Seller thereunder, other
than the Seller's obligation to pay not more than $134,500 of any rent accrued
but unpaid through the Closing).

         6.23     Agreement to Subordinate. At Closing, the Seller shall execute
and deliver to the Buyer and Buyer's lender the Subordination Agreement
(Contingent Amount) in the form attached hereto as EXHIBIT E ("SUBORDINATION
AGREEMENT"). In the event that, subsequent to the Closing, the Buyer or Zero
Zone, Inc. extends, amends (including, without limitation, any amendment
increasing the amount of the senior indebtedness), modifies, refinances or
replaces the senior debt described in the Subordination Agreement, whether in
whole or part and with the senior lender named in such Subordination Agreement
or with one or more different or other lenders, the Seller (together with any
Person to whom the Seller has transferred or assigned any rights to the
Contingent Amount), upon the request of the Buyer, shall execute any such other
or further subordination, intercreditor or similar agreement as may be requested
by the Buyer so as to subordinate the contingent Amount to the Buyer's or its
Related Persons' (including Zero Zone, Inc.'s) indebtedness to its or their
lenders, provided that no such subsequent subordination, intercreditor or
similar agreement shall impose subordination terms or conditions upon the Seller
as are materially more adverse to the interest of the Seller than those
contained in the Subordination Agreement.

                                   ARTICLE VII

                             COVENANTS OF THE BUYER

         The Buyer covenants and agrees with the Seller as follows:

         7.1      Certified Resolutions. On the Closing Date, the Buyer shall
deliver to the Seller a copy of the resolutions of the Buyer's Board of
Directors, authorizing and approving the execution of this Agreement and the
performance by the Buyer of the transactions contemplated hereby, certified by
the secretary or the president of the Buyer.

                                       38

<PAGE>

         7.2      Employment Agreement. On the Closing Date, the Buyer shall
execute and deliver to Theodore A. Mateski the Employment Agreement.

         7.2      Fulfill Conditions. The Buyer shall use its best efforts to
cause to be fulfilled on or prior to the Closing each of the conditions set
forth in Article IX hereof.

         7.4      The Buyer's Benefit Plans.

                  (a)      The Buyer's 401(k) Plan. Effective as of the Closing
Date, the Buyer shall provide Hired Employees with coverage under a defined
contribution profit-sharing plan with a cash or deferred arrangement that is
intended to be qualified under Sections 401(a) and 401(k) of the Code (the
"BUYER'S 401(k) PLAN"). The Buyer's 401(k) Plan shall provide credit to Hired
Employees for all of their service with the Seller, solely for purposes of
eligibility to participate and vesting, to the same extent such service would
have been credited if the service had been performed for the Buyer. After the
Closing Date, Buyer shall permit Hired Employees who are entitled and who elect
to receive an "eligible rollover distribution" (as described in Section
402(f)(2)(A) of the Code) from the Seller's 401(k) Plan to direct that the
eligible rollover distribution be transferred to the Buyer's 401(k) Plan in
accordance with Section 402(c) of the Code and the Buyer shall cause the Buyer's
401(k) Plan to contain provisions permitting such transfers.

                  (b)      The Buyer's Welfare Plans. The Buyer shall not assume
or continue any of the Seller's Benefit Plans. Other than the Buyer's 401(k)
Plan described in the preceding subsection of this Section, the Buyer shall
provide Hired Employees, as of the Closing Date, with such employee benefit
plans, programs, policies and arrangements (the "BUYER'S WELFARE PLANS") as the
Buyer may determine. With respect to medical and other health-related benefits,
the Buyer shall provide each Hired Employee (and each such Hired Employee's
spouses and dependents) with immediate coverage as of the Closing Date under a
"group health plan" (within the meaning of Section 5001(b) of the Code)
maintained by the Buyer (the "BUYER'S GROUP HEALTH PLAN") that provides benefits
and includes terms and conditions as determined by the Buyer, except that the
Buyer shall waive any pre-existing condition exclusions or restrictions with
respect to Hired Employees under the Buyer's Group Health Plan to the same
extent as coverage is provided under the Seller's Group Health Plan. Each Hired
Employee shall receive credit under the Buyer's Group Health Plan for all
amounts paid by each Hired Employee in calendar year 2002 under the Seller's
Group Health Plan for purposes of any applicable deductibles, co-payments or
out-of-pocket maximums for calendar year 2002. The Buyer shall be solely
responsible for providing Hired Employees with any continuation coverage (and
shall have sole liability in respect of any failure to provide such continuation
coverage) under Section 4980B of the Code or Part 6 of Subtitle B of Title I of
ERISA resulting from any "qualifying event" occurring on or after the Closing
Date. The Buyer shall grant full credit to Hired Employees under the Buyer's
Welfare Plans that are not group health plans, for service with the Seller for
purposes of (i) satisfying any and all eligibility and participation
requirements under the Buyer's Welfare Plans and (ii) determining the amount and
duration of any benefits under the Buyer's Welfare Plans to the extent that
service or seniority is a consideration in calculating benefits but the Buyer
shall not be required to credit any service that would result in a duplication
of benefits. The Seller shall have no obligation to provide nor any liability
for any benefits of any kind to Hired Employees under any of the Buyer's Welfare
Plans, including but not limited to COBRA benefits under any group health plan
of Buyer.

                  (c)Employment Terms and Benefits after the Closing Date.
Nothing in this Section or Section 6.20 shall be construed to limit or restrict
the Buyer in any way with respect to (i) the Buyer's conduct of the Business
after the Closing Date; (ii) the Buyer's modification or change in

                                       39

<PAGE>

the terms of employment (including the termination of employment) of any Hired
Employee; and (iii) the Buyer's modification, amendment or termination of any
employee benefit plan maintained or contributed to by the Buyer, including but
not limited to any of the Buyer's Welfare Plans.

                                  ARTICLE VIII

         10.3     Procedures for Making Claims. If and when a party (the
"INDEMNITEE") desires to assert a claim for Indemnifiable Damages against
another party or parties (collectively, the "INDEMNITOR") pursuant to the
provisions of this Article X, the Indemnitee shall deliver a Notice of Claim to
the Indemnitor. If the Indemnitor shall object to such Notice of Claim, the
Indemnitor shall simultaneously deliver a Notice of Objection to the Indemnitee
within fifteen (15) days after the Indemnitee's delivery of the Notice of Claim.
If the Notice of Objection shall not have been so delivered within such fifteen
(15) day period, all Indemnitors shall be conclusively deemed to have
acknowledged the correctness of the claim or claims specified in the Notice of
Claim for the full amount thereof, and the Indemnifiable Damages set forth in
the Notice of Claim shall be promptly paid to the Indemnitee, on demand, in
cash. If the Indemnitor shall make timely objection to a claim or claims set
forth in any Notice of Claim, and if such claim or claims shall not have been
resolved or compromised within sixty (60) days from the date of delivery of the
Notice of Objection, then such claims shall be settled by arbitration pursuant
to Section 11.5 hereof. The arbitrator shall promptly obtain such information
regarding the matter that the arbitrator deems necessary and shall decide the
matter and render a written award which shall be delivered to the Indemnitor and
Indemnitee. Any award shall be a conclusive determination of the matter and
shall be binding upon the Indemnitor and Indemnitee. If, by arbitration, it
shall be determined that the Indemnitee shall be entitled to any Indemnifiable
Damages by reason of its claim or claims, the Indemnifiable Damages so
determined shall be paid to the Indemnitee by the Indemnitor in the same manner
as if the Indemnitee had not delivered a Notice of Objection.

         10.4     Participation in Defense of Third Party Claims. If any third
Person shall assert any claim against an Indemnitee which, if successful, might
result in an obligation of the Indemnitor to pay Indemnifiable Damages and which
can be remedied to the sole satisfaction of the Indemnitee by the payment of
money damages without further adverse consequence to the Indemnitee, the
Indemnitor, at the sole expense of the Indemnitor, may assume the primary
defense thereof with counsel reasonably acceptable to the Indemnitee, but only
if and so long as: (i) the Indemnitor diligently pursues the defense of such
claim; and (ii) the Indemnitor acknowledges to the Indemnitee in writing that
the claim, if resolved or settled adversely to the Indemnitee, is one for which
the Indemnitor is obligated to indemnify the Indemnitee hereunder; and (iii) the
Indemnitor reasonably demonstrates to the Indemnitee that the Indemnitee
currently possesses sufficient cash and/or other liquid assets adequate to
defend and, if necessary, in the event that the claim is resolved or settled
adversely to the Indemnitor, satisfy the claim. If the Indemnitor fails or is
unable so to elect to assume the primary defense of any such claim, the
Indemnitee may (but need not) do so; in which event the Indemnitee may defend,
settle or compromise the claim, at the expense and cost of the Indemnitor, in
any such manner as the Indemnitee reasonably deems appropriate.

         10.5     Survival of Indemnification. An Indemnitor's obligation to pay
Indemnifiable Damages arising out of claims described in Sections 10.1(b),
10.1(c), 10.1(d), 10.2(b), 10.2(c) and 10.2(d) hereof shall survive the Closing
of this transaction indefinitely. The representations and warranties contained
in Articles IV and V hereof, and an Indemnitor's obligation to pay Indemnifiable
Damages arising out of Section 10.1(a) and 10.2(a) hereof, shall survive the
Closing Date, as follows:

                  (a)      Fraudulent Breach of Representations; Certain
Representations. In the case of a claim based upon the inaccuracy or Breach of a
representation or warranty which was made

                                       44

<PAGE>

fraudulently or with respect to any representation or warranty contained in
Sections 4.1 through and including 4.7, 4.10, 4.20, 4.30 and 4.31 hereof,
indefinitely;

                  (b)      Taxes. In the case of a claim based upon the
inaccuracy or Breach of a representation or warranty pertaining to taxes, for a
period equal to the applicable statute of limitations; and

                  (c)      All Other Claims. In the case of all other claims
based upon the inaccuracy or Breach of representation or warranty, for a period
commencing on the date hereof and ending on the date in 2006 that the Contingent
Amount, if any, becomes due as described in Section 2.1(c) hereof.

                  No claim for recovery of Indemnifiable Damages arising out of
Section 10.1(a) or Section 10.2(a) hereof may be asserted by an Indemnitee after
the expiration of the applicable time period described in the foregoing Sections
10.5(a)-(c); provided, however, that any claim first asserted by the giving of a
Notice of Claim within the applicable survival period shall neither be abated
nor barred.

         10.6     Offset. The Buyer shall be entitled (but not required) to
offset against any obligations now or hereafter owed by the Buyer to the Seller,
Mateski Properties, Shareholders or Members (including, without limitation, the
Contingent Amount which may become due and payable pursuant to Section 2.1(c)
hereof) the sum of all Indemnifiable Damages that the Buyer is entitled to
pursuant to Section 10.1 hereof. Any Indemnifiable Damages which the Buyer
elects to set-off against an obligation owed the Buyer shall be deemed "paid"
(for purposes of calculating the interest component of such Indemnifiable
Damages) not earlier than the date when the obligation against which the
Indemnifiable Damages are offset otherwise becomes fixed, due and payable to the
Seller, Mateski Properties, Shareholders or Members. For example, if
Indemnifiable Damages are incurred by the Buyer on July 1, 2002 and the Buyer
then elects to set-off such Indemnifiable Damages against the Contingent Amount
due the Seller pursuant to Section 2.1(c) hereof, such Indemnifiable Damages
shall not be deemed paid (for purposes of computing the interest component
thereof) until that time in 2006 (or, in the event of a prior disposition of the
Business, such earlier time) when such Contingent Amount becomes fixed, due and
payable. No offset made by the Buyer pursuant to this Section shall constitute a
default under any of the Buyer's payment obligations or, even if it is
subsequently determined that no Indemnifiable Damages were due the Buyer, give
rise to any right of acceleration.

         10.7     Limitations on Indemnifiable Damages.

                  (a)      Minimum Amount. Notwithstanding the foregoing, the
Buyer shall not be entitled to recover Indemnifiable Damages for any matter
described in Section 10.1(a) hereof (other than a claim under Section 10.1(a)
based upon a Breach of Sections 4.1 through and including 4.7, 4.10, 4.20, 4.22,
4.30 and 4.31) unless and until the aggregate of all claims for Indemnifiable
Damages asserted pursuant to Section 10.1(a) hereof exceeds $25,000 (but, if
such claims exceed $25,000 in the aggregate, the Buyer shall be entitled to
recover from the first dollar). Furthermore, the Buyer shall not be entitled to
recover the first $5,000 of Indemnifiable Damages for the matters described in
Section 10.1(e) hereof.

                  (b)      Assignment of Uncollected Receivables. In the event
that Indemnifiable Damages are payable to the Buyer because all or a portion of
the Receivables are not collected by the Buyer as herein provided, the Buyer
shall assign (without recourse) such Receivables (to the

                                       45

<PAGE>

extent uncollected) to the Seller promptly after payment by the Indemnitors of
the Indemnifiable Damages becoming due as a result of such noncollection.

                                   ARTICLE XI

                                  MISCELLANEOUS

         11.1     Further Assurances. Each party hereto from time to time
hereafter, and upon request, shall execute, acknowledge and deliver such other
instruments as reasonably may be required to more effectively transfer and vest
in the Buyer the Purchased Assets and Mateski Properties Purchased Assets or to
otherwise carry out the terms and conditions of this Agreement.

         11.2     Benefit and Assignment. This Agreement shall be binding upon
the parties hereto, their heirs, successors, assignees, and beneficiaries in
interest. No rights under this Agreement may be assigned nor any obligations
delegated, in whole or part, by the Seller, Mateski Properties, Shareholders or
Members, other than assignment of rights (in the case of the Shareholders or
Members, upon their death in accordance with their testamentary deposition or
the laws of intestacy or, in the case of the Seller or Mateski Properties, upon
their dissolution to their respective shareholders or members). The Buyer may
assign all or any of its rights and obligations under this Agreement (including,
without limitation, in favor of any Person providing financing to the Buyer).

         11.3     Governing Law. This Agreement shall be governed by and
construed in accordance with the internal Laws of the State of Minnesota
(regardless of such State's conflict of laws principles), and without reference
to any rules of construction regarding the party responsible for the drafting
hereof.

         11.4     Expenses. The Buyer shall pay all of its own expenses, fees or
costs incurred by it in connection with the negotiation, drafting and
performance of its obligations under this Agreement. The Shareholders and
Members (and not the Seller or Mateski Properties) shall pay all of the
expenses, fees and costs incurred by them, the Seller or Mateski Properties in
connection with the negotiation, drafting and performance of their, the Seller's
and Mateski Properties' obligations under this Agreement or the Settlement
Agreement or any other document executed in connection herewith or therewith
(including their legal accounting and other professional fees; costs of the
Commitment, the premiums for the title insurance policy and the Survey; transfer
taxes, and any costs incurred in connection with the procural of third Person
consents or Licenses), and none of such expenses, fees and costs shall have been
paid or be paid by or accrued as a liability of the Seller or Mateski
Properties.

         11.5     Arbitration. Any controversy, dispute or claim arising out of
or relating to this Agreement (including, but not limited to, any claim
regarding the scope or effect of this Section and any claim that this Section is
invalid or unenforceable), or the Breach hereof or thereof, shall be settled by
a single arbitrator in binding arbitration conducted in Madison, Wisconsin in
accordance with the Commercial Arbitration Rules of the American Arbitration
Association ("AAA") (or such other arbitration service as the parties may agree
upon), and judgment upon the award rendered by the arbitrator may be entered in
any court having jurisdiction thereof. The arbitrator's decision shall be in
writing. In addition to the Commercial Arbitration Rules of the AAA and unless
otherwise agreed to by the parties, the following rules shall apply:

                  (a)      Each party shall be entitled to discovery exclusively
                           by the following means: (i) requests for admission,
                           (ii) requests for production of documents, (iii) up

                                       46

<PAGE>

                           to 15 written interrogatories (with any subpart to be
                           counted as a separate interrogatory), and (iv)
                           depositions of no more than six individuals.

                  (b)      Unless the arbitrator finds that delay is reasonably
                           justified or as otherwise agreed to by the parties,
                           all discovery shall be completed, and the arbitration
                           hearing shall commence within five months after the
                           appointment of the arbitrator.

                  (c)      Unless the arbitrator finds that delay is reasonably
                           justified, the hearing will be completed, and an
                           award rendered within 30 days of commencement of the
                           hearing.

                  (d)      If the dispute submitted to arbitration arises from
                           disagreement concerning Adjusted EBITDA or the proper
                           calculation of the Contingent Amount pursuant to
                           Section 2.1(c) hereof, the arbitrator shall be a
                           partner at the Madison, Wisconsin office of a "Big
                           Five" firm of independent certified public
                           accountants having no then current relationship to
                           any of the Buyer, Seller, Mateski Properties,
                           Shareholders or Members.

The arbitrator's authority shall include the ability to render equitable types
of relief and, in such event, any aforesaid court may enter an Order enjoining
and/or compelling such actions or relief ordered or as found by the arbitrator.
The arbitrator also shall make a determination regarding which party's legal
position in any such controversy or claim is the more substantially correct (the
"Prevailing Party") and the arbitrator shall require the other party to pay the
legal and other professional fees and costs incurred by the Prevailing Party in
connection with such arbitration proceeding and any necessary court action.
However, notwithstanding the foregoing, the parties expressly agree that a court
of competent jurisdiction may enter a temporary restraining order or an order
enjoining a Breach of this Agreement pending a final award or further order by
the arbitrator. Such remedy, however, shall be cumulative and nonexclusive, and
shall be in addition to any other remedy to which the parties may be entitled.

         11.6     Notices. Any and all notices, demands, and communications
provided for herein or made hereunder shall be given in writing and shall be
deemed given to a party at the earlier of (i) when actually delivered to such
