         Period, in the Lender's sole discretion and without waiving any of its
         other rights and remedies, the principal of the Advances outstanding
         from time to time shall bear interest at the Default Rate, effective

         Default Period.

         auditor), together with all actual out-of-pocket costs and expenses
         incurred in conducting any such audit or inspection; provided that so
         long as WFBCI is the Servicer the Borrower shall not have to reimburse
         such costs and expenses to the extent it has already done so pursuant
         to the WFBCI Credit Facility.

                  Section 2.5 Capital Adequacy; Increased Costs and Reduced
Return. If any Related Lender determines at any time that its Return has been
reduced as a result of any Rule Change, such Related Lender may require the
Borrower to pay it the amount necessary to restore its Return to what it would
have been had there been no Rule Change. For purposes of this Section 2.10:

                  (a) "Capital Adequacy Rule" means any law, rule, regulation,
         guideline, directive, requirement or request regarding capital
         adequacy, or the interpretation or administration thereof by any
         governmental or regulatory authority, central bank or comparable
         agency, whether or not having the force of law, that applies to any
         Related Lender. Such rules include rules requiring financial
         institutions to maintain total capital in amounts based upon
         percentages of outstanding loans, binding loan commitments and letters
         of credit.

                  (c) "Return", for any period, means the return as determined
         by such Related Lender on the Advances based upon its total capital
         requirements. Return may be calculated for each calendar quarter and
         for the shorter period between the end of a calendar quarter and the
         date of termination in whole of this Agreement.

                  (d) "Rule Change" means any change in any Capital Adequacy
         Rule occurring after the Closing Date, but the term does not include
         any changes in applicable requirements that on the Closing Date are
         scheduled to take place under the existing Capital Adequacy Rules or
         any increases in the capital that any Related Lender is required to
         maintain to the extent that the increases are required due to a
         regulatory authority's assessment of the financial condition of such
         Related Lender.


                                      -12-



                  (e) "Related Lender" includes (but is not limited to) the
         Lender, any parent corporation of the Lender and any assignee of any
         interest of the Lender hereunder and any participant in the loans made
         hereunder.

Certificates of any Related Lender sent to the Borrower from time to time
claiming compensation under this Section 2.5, stating the reason therefor and
setting forth in reasonable detail the calculation of the additional amount or
amounts to be paid to the Related Lender hereunder to restore its Return shall
be conclusive absent manifest error. In determining such amounts, the Related
Lender may use any reasonable averaging and attribution methods.

                  Section 2.6 Termination by the Borrower. The Borrower may
terminate this Agreement at any time upon 30 days' prior written notice to the
Lender so long as no Letter of Credit has been issued and is outstanding with an
expiration date after such date, and, subject to payment and performance of all
Obligations, may obtain any release or termination of the Security Interest to
which the Borrower is otherwise entitled by.

                  Section 2.7 Mandatory Prepayment. Without notice or demand, if
(i) the Borrowing Base shall at any time be less than the outstanding principal
balance of the Advances, the Borrower shall immediately prepay the Advances to
the extent necessary to eliminate such deficiency or increase the Borrowing Base
by furnishing additional Collateral to the Lender in form and amount
satisfactory to the Lender and Ex-Im Bank.

                  Section 2.8 Advances Without Request. The Borrower hereby
authorizes the Lender, in its discretion, at any time or from time to time
without the Borrower's request, to make Advances to pay accrued interest, fees,
uncollected items that have been applied to the Obligations, and other
Obligations due and payable from time to time.

                  Section 2.9 Use of Proceeds. The Borrower shall use the
proceeds of Advances for working capital to finance the manufacture, assembly,
production or purchase and subsequent sale of Items only. Without limiting the
generality of the foregoing, the Borrower shall not use any proceeds of Advances
for any purpose prohibited by the Borrower Agreement or (i) to acquire fixed
assets or capital goods for use in the Borrower's business; (ii) to acquire,
equip or rent commercial space overseas; (iii) to employ non-US residents in
offices outside the US; (iv) to serve as a retainage or warranty bond; or (v) to
repay pre-existing Debt or future indebtedness of the Borrower unrelated to the
Advances.

                  Section 2.10 Facility Subject to Ex-Im Bank Rules. The
Borrower acknowledges that the Lender is willing to make the Credit Facility
available to the Borrower because the Ex-Im Bank is willing to guaranty payment
of a significant portion of the Obligations pursuant to the Master Guaranty.
Accordingly, in the event of any inconsistency among the Loan Documents and the
Master Guaranty or related documents, the provision that is the more stringent
on the Borrower shall control.

the amount due that such right to payment has been assigned or transferred to
the Lender for security and shall be paid directly to the Lender. The Borrower
will join in giving such notice if the Lender so requests. At any time after the
Borrower or the Lender gives such notice to an account debtor or other obligor,
the Lender may, but need not, as the Borrower's agent and attorney-in-fact,
notify the US Postal Service to change the address for delivery of the
Borrower's mail to any address designated by the Lender, otherwise intercept the
Borrower's mail, and receive, open and dispose of the Borrower's mail, applying
all Collateral as permitted under this Agreement and holding all other mail for
the Borrower's account or forwarding such mail to the Borrower's last known
address.

                  Section 3.3 Assignment of Insurance. As additional security
for the payment and performance of the Obligations, the Borrower hereby assigns
to the Lender any and all monies (including, without limitation, proceeds of
insurance and refunds of unearned premiums) due or to become due under, and all
other rights of the Borrower with respect to, any and all policies of insurance
now or at any time hereafter covering the Collateral or any evidence thereof or
any business records or valuable papers pertaining thereto, and the Borrower
hereby directs the issuer of any such policy to pay all such monies directly to
the Lender. At any time, whether or not a Default Period then exists, the Lender
may (but need not), in the Lender's name or in the Borrower's name, execute and
deliver proof of claim, receive all such monies, endorse checks and other
instruments representing payment of such monies, and adjust, litigate,
compromise or release any claim against the issuer of any such policy.

                  Section 3.4 Occupancy.

                  (a) The Borrower hereby irrevocably grants to the Lender the
         right to take exclusive possession of the Premises at any time during
         any Default Period.

                  (b) The Lender may use the Premises only to hold, process,
         manufacture, sell, use, store, liquidate, realize upon or otherwise
         dispose of goods that are Collateral and for other purposes that the
         Lender in good faith considers related.


                                      -14-



                  (c) The Lender's right to hold the Premises shall terminate
         upon the earlier of payment in full of all Obligations, or final sale
         or disposition of all goods constituting Collateral and delivery of all
         such goods to purchasers.

                  (d) The Lender shall not be obligated to pay or account for
         any rent or other compensation for the possession or use of any of the
         Premises; provided, however, that if the Lender does pay or account for
         any rent or other compensation for the possession or use of any of the
         Premises, the Borrower shall reimburse the Lender promptly for the full
         amount thereof.

                  Section 3.5 License. Without limiting the generality of the
Patent and Trademark], the Borrower hereby grants to the Lender a non-exclusive,
worldwide and royalty-free license to use or otherwise exploit all trademarks,
franchises, trade names, copyrights and patents of the Borrower for the purpose
of selling, leasing or otherwise disposing of any or all Collateral following an
Event of Default.

                  Section 3.6 Filing a Copy. A carbon, photographic, or other
reproduction of this Agreement or of a financing statement signed by the
Borrower is sufficient as a financing statement.

                  Section 8.2 Servicing of Credit Facility.

                  (a) The Lender has requested that the Servicer service and
         enforce the Loan Documents, make all Advances, cause all Letters of
         Credit to be issued, and collect all Obligations on the Lender's behalf
         and the Servicer has agreed to do so. The Borrower acknowledges and
         accepts the Servicer's appointment as such.

                  (b) The Servicer shall have no duties or responsibilities to
         the Borrower hereunder, but only to the Lender. Neither the Servicer
         nor any of its officers, directors, employees or agents shall be liable
         for any action taken or omitted by them hereunder or in connection
         herewith, unless caused by its or their willful misconduct. The
         Servicer's duties shall be mechanical and administrative in nature;
         nothing in this Agreement, express or implied, is intended to or shall
         be so construed as to impose upon the Servicer any obligations with
         respect to the Loan Documents except as expressly set forth herein.
         Neither the Borrower nor any Guarantor shall in any way


                                      -26-



         be construed to be a third party beneficiary of any relationship
         between the Servicer and the Lender.

                  (c) The Servicer shall be entitled to rely, and shall be fully
         protected in relying, upon any communication whether written or oral
         believed by it to be genuine and correct and to have been signed, sent
         or made by the proper Person, and, with respect to all legal matters
         pertaining to this Agreement and its duties hereunder, upon advice of
         counsel selected by it.

                  (d) The Borrower shall be entitled to rely upon any
         communication whether written or oral sent or made by the Servicer for
         and on behalf of the Lender with respect to all matters pertaining to
         the Loan Documents and the Borrower's duties and obligations hereunder,
         unless and until the Borrower receives written notice from the Lender
         that the Servicer is no longer servicing this credit facility.

                  (e) The Servicer shall hold and be the custodian of the Loan
         Documents on the Lender's behalf for so long as the Servicer is
         servicing the Credit Facility.

                  Section 8.3 Costs and Expenses. The Borrower agrees to pay on
demand all costs and expenses (including legal fees) incurred by the Lender in
connection with the Loan Documents, any Letters of Credit, and any other
document or agreement related thereto, and the transactions contemplated hereby,
including wire transfer and ACH charges, the cost of credit reports, overadvance
fees, the expense of any auditors and fees and expenses in enforcing this
Agreement.

                  Section 8.4 Indemnity. In addition to the payment of expenses
pursuant to Section 8.3, the Borrower agrees to indemnify, defend and hold
harmless the Lender, and any of its participants, parent corporations,
subsidiary corporations, affiliated corporations, successor corporations, and
all present and future officers, directors, employees, attorneys and agents of
the foregoing (the "Indemnitees") from and against any of the following
(collectively, "Indemnified Liabilities"):

                           (i) any and all transfer taxes, documentary taxes,
                  assessments or charges made by any governmental authority by
                  reason of the execution and delivery of this Agreement and the
                  other Loan Documents or the making of the Advances;

                           (ii) any and all liabilities, losses, damages,
                  penalties, judgments, suits, claims, costs and expenses of any
                  kind or nature whatsoever (including, without limitation, the
                  reasonable fees and disbursements of counsel) in connection
                  with any investigative, administrative or judicial
                  proceedings, whether or not such Indemnitee shall be
                  designated a party thereto, which may be imposed on, incurred
                  by or asserted against any such Indemnitee, in any manner
                  related to or arising out of or in connection with the making
                  of the


                                      -27-



                  Advances, this Agreement and the other Loan Documents or the
                  use or intended use of the proceeds of the Advances; and

                           (iii) any claim, loss or damage to which any
                  Indemnitee may be subjected as a result of any violation of
                  any federal, state, local or other governmental statute,
                  regulation, law, or ordinance dealing with the protection of
                  human health and the environment.

If any investigative, judicial or administrative proceeding arising from any of
the foregoing is brought against any Indemnitee, then the Borrower or counsel
designated by the Borrower and satisfactory to the Indemnitee, will resist and
defend such action, suit or proceeding to the extent and in the manner directed
by the Indemnitee. Each Indemnitee will use its best efforts to cooperate in the
defense of any such action, suit or proceeding. If the foregoing undertaking to
indemnify, defend and hold harmless may be held to be unenforceable because it
violates any law or public policy, the Borrower shall nevertheless make the
maximum contribution to the payment and satisfaction of each of the Indemnified
Liabilities which is permissible under applicable law. The Borrower's obligation
under this Section 8.4 shall survive the termination of this Agreement and the
discharge of the Borrower's other obligations hereunder. If Ex-Im Bank makes
payment of a claim to the Lender under the Master Guaranty in connection with
the Credit Facility, Ex-Im Bank may assume all rights and remedies of the Lender
under the Loan Documents and may enforce any such rights or remedies against the
Borrower, the Collateral and any Guarantors. the Borrower shall hold Ex-Im Bank
and the Lender harmless from and indemnify them against any and all liabilities,
damages, claims, costs and losses incurred or suffered by either of them
resulting from (a) any materially incorrect certification or statement knowingly
made by the Borrower or its agent to Ex-Im Bank or the Lender in connection with
the Loan Facility, this Agreement, the Loan Authorization Agreement or any other
Loan Documents or (b) any material breach by the Borrower of the terms and
conditions of this Agreement, the Loan Authorization Agreement or any of the
other Loan Documents. the Borrower also acknowledges that any statement,
certification or representation made by the Borrower in connection with the Loan
Facility is subject to the penalties provided in Article 19 U.S.C. Section 1001.

                  Section 8.5 Binding Effect; Assignment; Counterparts;
Exchanging Information. The Loan Documents shall be binding upon and inure to
the benefit of the Borrower and the Lender and their respective successors and
assigns, except that the Borrower shall not have the right to assign its rights
thereunder or any interest therein without the prior written consent of the
Lender. This Agreement and other Loan Documents may be executed in any number of
counterparts, each of which when so executed and delivered shall be deemed to be
an original and all of which counterparts, taken together, shall constitute but
one and the same instrument. Without limiting the Lender's right to share
information regarding the Borrower and its Affiliates with the Lender's
participants, accountants, lawyers and other advisors, the Lender, Norwest
Corporation, and all direct and indirect subsidiaries of Norwest Corporation,
may exchange any and all information they may have in their possession regarding
the Borrower and its Affiliates, and the Borrower


                                      -28-



waives any right of confidentiality it may have with respect to such exchange of
such information.

                  Section 8.7 Governing Law; Jurisdiction, Venue; Waiver of Jury
Trial. This Agreement and the Note shall be governed by and construed in
accordance with the laws (other than conflict laws) of the State of Minnesota.
Each party consents to the personal jurisdiction of the state and federal courts
located in the State of Minnesota in connection with any controversy related to
this Agreement, waives any argument that venue in any such forum is not
convenient and agrees that any litigation initiated by any of them in connection
with this Agreement shall be venued in either the District Court of Hennepin
County, Minnesota, or the United States District Court, District of Minnesota,
Fourth Division. THE PARTIES WAIVE ANY RIGHT TO TRIAL BY JURY IN ANY ACTION OR
PROCEEDING BASED ON OR PERTAINING TO THIS AGREEMENT.

                  IN WITNESS WHEREOF, the parties hereto have signed this
Agreement as of the date first above written.
