                       GENERAL BUSINESS SECURITY AGREEMENT

                                                          Dated October 14, 2002

         1. SECURITY INTEREST. The undersigned ("Debtor", whether one or more)
grants AnchorBank, fsb ("Lender") a security interest in all equipment,
fixtures, inventory, documents, general intangibles, accounts, deposit accounts
(unless a security interest would render a nontaxable account taxable) contract
rights, chattel paper, instruments, letter of credit rights and investment
property, now owned or hereafter acquired by Debtor, and all additions and
accessions to, all spare and repair parts, special tools, equipment and
replacements for, software used in, all returned or repossessed goods the sale
of which gave rise to and all proceeds, supporting obligations and products of
the foregoing ("Collateral"), wherever located, to secure all debts, obligations
and liabilities of any Debtor to Lender arising out of credit previously
granted, credit contemporaneously granted and credit granted in the future by
Lender to any Debtor, to any Debtor and another, or to another guaranteed or
indorsed by any Debtor ("Obligations").

         2. DEBTOR'S WARRANTIES. Debtor warrants that while any of the
Obligations are unpaid:

         (a) Ownership and use. Debtor owns the Collateral free of all
encumbrances and security interests (except Lender's security interest). Chattel
paper constituting Collateral evidences a perfected security interest in the
goods (including software used in the goods) covered by it, free from all other
encumbrances and security interests, and no financing statement is on file or
control agreement in existence (other than Lender's) covering the Collateral or
any of it. Debtor, acting alone, may grant a security interest in the
Collateral. The Collateral is used or bought for use primarily for business
purposes.

         (b) Sale of goods or services rendered. Each account and chattel paper
constituting Collateral as of this date arose from the performance of services
by Debtor or from a bona fide sale or lease of goods, which have been delivered
or shipped to the account debtor and for which Debtor has genuine invoices,
shipping documents or receipts.

         (c) Enforceability. Each account, contract right and chattel paper
constituting Collateral as of this date is genuine and enforceable against the
account debtor according to its terms. It and the transaction out of which it
arose comply with all applicable laws and regulations. The amount represented by
Debtor to Lender as owing by each account debtor is the amount actually owing
and is not subject to setoff, credit, allowance or adjustment, except discount
for prompt payment, nor has any account debtor returned the goods or disputed
liability.

         (d) Due date. There has been no default as of this date according to
the terms of any chattel paper or account constituting Collateral and no step
has been taken to foreclose the security interest it evidences or otherwise
enforce its payment.

<PAGE>

         (e) Financial condition of account debtor. As of this date Debtor has
no notice or knowledge of anything which might impair the credit standing of any
account debtor.

         (f) Valid organization. Debtor is duly organized, validly existing and
in good standing under the laws of the state of organization and is authorized
to do business in Wisconsin.

         (g) Other agreements. Debtor is not in default under any agreement for
the payment of money, other than those identified for settlement in the Accord
(as that term is used in Section IV of that certain Commitment Letter dated
October 1, 2002 between Lender and Debtor).

         (h) Authority to contract. The execution and delivery of this Agreement
and any instruments evidencing Obligations will not violate or constitute a
breach of Debtor's certificate of incorporation, by-laws, or any other agreement
or restriction to which Debtor is a party or is subject.

         (i) Accuracy of information. All information, certificates or
statements given to Lender pursuant to this Agreement shall be true and complete
when given.

         (j) Name and address. Debtor's exact legal name is as set forth below
Section 5. The address of Debtor's chief executive office is as set forth below
Section 5.

without prior written consent of Lender, but the parties intend that the
Collateral, wherever located, is covered by this Agreement.

         (l) Organization. Debtor's type of organization and the state under
whose law Debtor is organized are as set forth below Section 5.

         (m) Environmental laws. (i) No substance has been, is or will be
present, used, stored, deposited, treated, recycled or disposed of on, under, in
or about any real estate now or at anytime owned or occupied by Debtor
("Property") during the period of Debtor's ownership or use of the Property in a
form, quantity or manner which if known to be present on, under, in or about the
Property would require clean-up, removal or some other remedial action
("Hazardous Substance") under any federal, state or local laws, regulations,
ordinances, codes or rules ("Environmental Laws"), (ii) Debtor has no knowledge
of any prior use or existence of any Hazardous Substance on the Property by any

to any court or administrative proceeding, judgment, decree, order or citation
relating to any such substance, and (vi) Debtor in the past has been, at the

employees and agents from all loss, cost (including reasonable attorneys' fees
and legal expenses), liability and damage whatsoever directly or indirectly
resulting from, arising out of, or based upon (i) the presence, use, storage,
deposit, treatment, recycling or disposal, at any time, of any Hazardous
Substance on, under, in or about the Property, or the transportation of any such
substance to or from the Property, (2) the violation or alleged violation of any
Environmental Law, permit, judgment or license relating to the presence, use,
storage, deposit, treatment, recycling or disposal of any Hazardous Substance
on, under, in or about the Property, or the transportation of any Hazardous
Substance to or from Property, or (3) the imposition of any governmental lien
for the recovery of environmental clean up costs expended under any
Environmental Law. Debtor shall immediately notify Lender in writing of any
governmental or regulatory action or third-party claim instituted or threatened
in connection with any Hazardous Substance described above on, in, under or
about the Property.

         (n) Fixtures. If any of the Collateral is affixed to real estate, the
legal description of the real estate set forth in each UCC Financing Statement
signed or authorized by Debtor is true and correct.

         3. SHIPPERS. There are no Shippers authorized to draw drafts on Lender
under Section 7(c).

         4. SALE AND COLLECTIONS.

         (a) Sale of Collateral. Debtor may sell equipment and furniture which
are part of the Collateral, at commercially reasonable prices, and may retain
the first $400,000 of proceeds from such sales. Debtor will provide Lender with
prompt notice of sales of such furniture and equipment and the proceeds received
from sales. To the extent proceeds from sales of furniture and equipment exceed
a total of $400,000, Debtor shall remit proceeds in excess of $400,000 to Lender
for application against the Obligations not later than the third business day
following the day of their receipt.

         (b) Sale of Inventory in Ordinary Course. So long as no default exists
under any of the Obligations or this Agreement, Debtor may (a) sell inventory in
the ordinary course of Debtor's business for cash or on terms customary in the
trade, at prices not less than any minimum sale price shown on instruments
evidencing Obligations and describing inventory, or (b) lease or license
inventory on terms customary in the trade.

         (c) Verification and notification. Lender may verify Collateral in any
manner, and Debtor shall assist Lender in so doing. Upon default Lender may at
any time and Debtor shall, upon request of Lender, notify the account debtors or
other persons obligated on the Collateral to make payment directly to Lender and
Lender may enforce collection of, settle,

                                       3
<PAGE>

compromise, extend or renew the indebtedness of such account debtors or other
persons obligated on the Collateral. Until account debtors or other persons
obligated on the Collateral are so notified, Debtor, as agent of Lender, shall
make collections and receive payments on the Collateral.

         (d) Deposit with Lender. At any time Lender may require that all
proceeds of Collateral received by Debtor shall be held by Debtor upon an
express trust for Lender, shall not be commingled with any other funds or
property of Debtor and shall be turned over to Lender in precisely the form
received (but endorsed by Debtor if necessary for collection) not later than the
fifth banking day following the day of their receipt. Except as provided in
Section 4(e) below, all proceeds of Collateral received by Lender directly or
from Debtor shall be applied against the Obligations in such order and at such
times as Lender shall determine.

         (e) Accounting. If the extent to which Lender's security interest in
the Collateral is a purchase money security interest depends on the application
of a payment to a particular obligation of Debtor, the payment shall first be
applied to obligations of Debtor for which Debtor did not create a security
interest in the order in which those obligations were incurred and then to
obligations of Debtor for which Debtor did create a security interest, including
the Obligations secured by the Collateral, in the order in which those
obligations were incurred; provided, however, that Lender shall retain its
security interest in all Collateral regardless of the allocation of payments.

         5. PERSONS BOUND AND OTHER PROVISIONS. The obligations hereunder of all
Debtors are joint and several. This Agreement benefits Lender, its successors
and assigns, and binds Debtor(s) and their respective successors and assigns and
shall bind all persons and entities who become bound as a debtor to this
Agreement.

         (a) Maintenance of Collateral. Debtor shall: maintain the Collateral in
good condition and repair and not permit its value to be impaired; keep it free
all liens, encumbrances and security interests (other than Lender's security
interest); defend it against all claims and legal proceedings by persons other
than Lender; pay and discharge when due all taxes, license fees, levies and
other charges upon it (unless contested in good faith in appropriate
proceedings); not sell, lease, license or otherwise transfer or dispose of it
(except as permitted herein) or permit it to become a fixture or an accession to
other goods, except for sales, leases or licenses of inventory as provided in
this Agreement; not permit it to be used in violation of any applicable law,
regulation or policy of insurance; and, as to Collateral consisting of
instruments, chattel paper and letter of credit rights, preserve rights in it
against prior parties. Loss of or damage to the Collateral shall not release

         (b) Insurance. Debtor shall keep the Collateral and Lender's interest
in it insured under policies with such provisions, for such amounts and by such
insurers as shall be satisfactory to Lender from time to time, and shall furnish
evidence or such insurance satisfactory to Lender. Subject to Lender's
satisfaction, Debtor is free to select the insurance agent or insurer through
which the insurance is obtained. Debtor assigns (and directs any insurer to pay)
to Lender the proceeds of all such insurance and any premium refund, and
authorizes Lender to indorse in the name of Debtor any instruments for such
proceeds or refunds and, at the option of Lender, to apply such proceeds and
refunds to any unpaid balance of the Obligations, whether or not due, and/or to
restoration of the Collateral, returning any excess to Debtor. Lender is
authorized, in the name of Debtor or otherwise, to make, adjust and/or settle
claims under any credit insurance financed by Lender or any insurance on the
Collateral, or cancel the same after the occurrence of an event of default.

         (c) Maintenance of security interest. Debtor shall pay all expenses and
upon request, take any action reasonably deemed advisable by Lender to preserve
the Collateral or to establish, evidence, determine and maintain priority of,
perfect, continue perfected, terminate and/or enforce Lender's interest in it or
rights under this Agreement. Debtor authorizes Lender to file Uniform Commercial
Code financing statements describing the Collateral (including describing the
Collateral as "all assets", "all personal property" or with words of similar
effect) and amendments to such financing statements and ratifies any such
financing statement or amendment filed prior to the date of this Agreement.
Debtor will cooperate with Lender in obtaining control of Collateral or other
security for the Obligations for which control may be required to perfect
Lender's security interest under applicable law. If the Collateral is in
possession of a third party, Debtor will join with Lender at its request in
notifying the third party of Lender's security interest and obtaining an
acknowledgment from the third party that it is holding the Collateral for the
benefit of Lender.

         (d) Taxes and other charges. Debtor shall pay and discharge all lawful
taxes, assessments and government charges upon Debtor or against its properties
prior to the date on which penalties attach, unless and to the extent only that
such taxes, assessments and charges are contested in good faith and by
appropriate proceedings by Debtor.

         (e) Records and statements. Debtor shall furnish to Lender financial
statements at least annually and such other financial information respecting
Debtor at such times and in such form as Lender may request. Debtor shall keep
accurate and correct records respecting the Collateral in such form as Lender
may approve. At such times as Lender may require, Debtor shall furnish to Lender
a statement certified by Debtor and in such form and containing such information
as may be prescribed by Lender, showing the current status and value of the
Collateral.

         (f) Inspection of Collateral. At reasonable times Lender may examine
the Collateral and Debtor's records pertaining to it, wherever located, and make
copies of records, and Debtor shall assist Lender in so doing.

         (g) Service charge. In addition to the required payments under the
Obligations and this Agreement, Debtor shall pay Lander's then current service
charges for servicing and auditing in connection with this Agreement.

         (h) Chattel paper. Lender may require that chattel paper constituting
Collateral shall be on forms approved by Lender. Unless it consists of
electronic chattel paper, Debtor shall promptly mark all chattel paper
constituting Collateral, and all copies, to indicate conspicuously Lender's
interest and, upon request, deliver them to Lender. If it consists of electronic
chattel paper, Debtor shall promptly notify Lender of the existence of the
electronic chattel paper and, at the request of Lender, shall take such actions
as Lender may reasonably request to vest in Lender control of such electronic
chattel paper under applicable law.

         (i) United States contracts. If any Collateral arose out of contracts
with the United States or any of its departments, agencies or instrumentalities,
Debtor will notify Lender and execute writings required by Lender in order that
all money due or to become due under such contracts shall be assigned to Lender
and proper notice of the assignment given under the Federal Assignment of Claims
Act.

         (j) Modifications. Without the prior written consent of Lender, Debtor
shall not alter, modify, extend, renew or cancel any accounts, letter of credit
rights or chattel paper constituting Collateral or any Collateral constituting
part of the Debtor's borrowing base.

         (k) Returns and repossessions. Debtor shall promptly notify Lender of
the return to or repossession by Debtor of goods underlying any Collateral and
Debtor shall hold and dispose of them only as Lender directs.

         (l) Promissory Notes, Chattel Paper and Investment Property. If Debtor
shall at any time hold or acquire Collateral consisting of promissory notes,
chattel paper or certificated securities, Debtor shall endorse, assign and
deliver the same to Lender accompanied by such instruments of transfer or
assignment duly executed in blank as Lender may from time to time request.

         (m) Change of name, address or organization. Debtor shall not change
Debtor's legal name or address without providing at least 30 days prior written
notice of the change to Lender. Debtor shall not change its type of organization
or state under whose law it is organized and shall preserve its organizational
existence, and Debtor shall not, in one transaction or in a series of related
transactions, merge into or consolidate with any other organization, change
Debtor's legal structure or sell or transfer all or substantially all of
Debtor's assets without Lender's prior written consent, which shall not be
unreasonably withheld or delayed.

         7. RIGHTS OF LENDER.

         (a) Authority to perform for Debtor. Upon the occurrence of an event of
default or if Debtor fails to perform any of Debtor's duties set forth in this
Agreement or in any evidence of or document relating to the Obligations, Lender
is authorized, in Debtor's name

                                       6
<PAGE>

or otherwise, to take any such action including without limitation signing
Debtor's name or paying any amount so required, and the cost shall be one of the
Obligations secured by this Agreement and shall be payable by Debtor upon demand
with interest from the date of payment by Lender at the highest rate stated in
any evidence of any Obligation but not in excess of the maximum rate permitted
by law.

         (b) Charging Debtor's credit balance. Unless a lien would be prohibited
by law or would render a nontaxable account taxable, Debtor grants Lender, as
further security for the Obligations, a security interest and lien in any
deposit account Debtor may at any time have with Lender and other money now or
hereafter owed Debtor by Lender, and agrees that Lender may, at any time after
the occurrence of an event of default, without prior notice or demand, set off
all or a part of the unpaid balance of the Obligations against any deposit
balances or other money now or hereafter owed Debtor by Lender.

         (c) Power of attorney. Debtor irrevocably appoints any officer of
Lender as Debtor's attorney, with power after an event of default to receive,
open and dispose of all mail addressed to Debtor (and Lender shall not be
required as a condition to the exercise of this power to prove the occurrence of
an event of default to the Post Office); to notify the Post Office authorities
to change the address for delivery of all mail addressed to Debtor to such
address as Lender may designate; to endorse the name of Debtor upon any
instruments which may come into Lender's possession; and to sign and make draws
under any letter of credit constituting Collateral on Debtor's behalf. Debtor
agrees that Obligations may be created by drafts drawn on Lender by shippers of
inventory named in Section 3. Debtor authorizes Lender to honor any such draft
accompanied by invoices aggregating the amount of the draft and describing
inventory to be shipped to Debtor and to pay any such invoices not accompanied
by drafts. Debtor appoints any employee of Lender as Debtor's attorney, with
full power to sign Debtor's name on any instrument evidencing an Obligation. or
any renewals or extensions, for the amount of such drafts honored by Lender and
such instruments may be payable at fixed times or on demand, shall bear interest
at the rate from time to time fixed by Lender and Debtor agrees, upon request of
Lender, to execute any such instruments. This power of attorney to execute
instruments may be revoked by Debtor only written notice to Lender and no such
revocation affect any instruments executed prior to the receipt by Lender of
such notice. All acts of such attorney are ratified and approved and such
attorney is not liable for any act or omission or for any error of judgment or
mistake of fact or law.

         (d) Non-liability of Lender. Lender has no duty to determine the
validity of any invoice, the authority of any shipper named in Section 3 to ship
goods to Debtor or compliance with any order of Debtor. Lender has no duty to
protect, insure, collect or realize upon the Collateral or preserve rights in it
against prior parties. Debtor releases Lender from any liability for any actor
omission relating to the Obligations, the Collateral or this Agreement, except
Lender's willful misconduct.

                                       7
<PAGE>

         8. DEFAULT. Upon the occurrence of one or more of the following events
of default:

         (a) Nonperformance. Debtor fails to pay when due any of the Obligations
or to perform, or rectify breach of, any warranty or covenant or other
undertaking by Debtor in this Agreement or in any evidence of or document
relating to the Obligations or an event of default occurs under any evidence of
or document relating to any other obligation secured by the Collateral;

         (b) Inability to Perform. Debtor or a surety for any of the Obligations
dies, ceases to exist, becomes insolvent or the subject of bankruptcy or
insolvency proceedings or any guaranty of the Obligations is revoked or becomes
unenforceable for any reason;

         (c) Misrepresentation. Any representation made to induce Lender to
extend credit to Debtor, under this Agreement or otherwise, is false in any
material respect when made; or

         (d) Insecurity. Any other event which causes Lender in good faith to
deem itself insecure:

all of the Obligations shall, at the option of Lender and without notice or
demand, become immediately payable; and Lender shall have all rights and
remedies for default provided by the Wisconsin Uniform Commercial Code, as well
as any other applicable law and any evidence of or document relating to any
Obligation. With respect to such rights and remedies:

         (e) Repossession. Lender may take possession of Collateral without
notice or hearing, which Debtor waives;

         (f) Assembling collateral. Lender may require Debtor to assemble the
Collateral and to make it available to Lender at any place reasonably designated
by Lender;

         (g) Notice of disposition. Written notice, when required by law, sent
to any address of Debtor in this Agreement at least 10 calendar days (counting
the day of sending) before the date of a proposed disposition of the Collateral
is reasonable notice;

         (h) Expenses and application of proceeds. Debtor shall reimburse Lender
for any expense incurred by Lender in protecting or enforcing its rights under
this Agreement before and after judgment, including, without limitation,
reasonable attorneys' fees and legal expenses of taking possession, holding,
preparing for disposition and disposing of Collateral (provided, however, Lender
has no obligation to clean-up or otherwise prepare the Collateral for sale).
After deduction of such expenses, Lender shall apply the proceeds of disposition
to the extent actually received in cash to the Obligations in such order and
amounts as it elects or as otherwise required by this Agreement; and

         (i) Waiver. Lender may permit Debtor to remedy any default without
waiving the default so remedied, and Lender may waive any default without
waiving any other subsequent or prior default by Debtor.
