Borrower:  Transcrypt International, Inc.    Lender:  U.S. Bank National
           4800 NW 1st Street                Association
           Lincoln, NE 68521-9918            Lincoln Main

Principal Amount: $10,000,000.00  Initial Rate: 6.320%          Date of Note:
                                                                August 31, 1999

PROMISE TO PAY. Transcrypt International, Inc. ("Borrower") promises to pay to
U.S. Bank National Association ("Lender"), or order, In lawful money of the
United States of America, the principal amount of Ten Million & 00/100 Dollars
($10,000,000.00) or so much as may be outstanding, together with Interest on the
unpaid outstanding principal balance of each advance. INTEREST SHALL BE
CALCULATED FROM THE DATE OF EACH ADVANCE until repayment of each advance.

PAYMENT. Borrower will pay this loan in one payment of all outstanding principal
plus all accrued unpaid Interest on June 1, 2000. In addition, Borrower will pay
regular monthly payments of accrued unpaid Interest beginning September 30,
1999, and all subsequent Interest payments are due on the last day of each month
after that. The annual Interest rate for this Note is computed on a 365/360
basis; that Is, by applying the ratio of the annual Interest rate over a year of
360 days, multiplied by the outstanding principal balance, multiplied by the
actual number of days the principal balance is outstanding. Borrower will pay
Lender at Lender's address shown above or at such other place as Lender may
designate in writing. Unless otherwise agreed or required by applicable law,
payments will be applied FIRST to accrued unpaid Interest, then to principal,
and any remaining amount to any unpaid collection costs and late charges.

VARIABLE INTEREST RATE. The Interest rate on this Note Is subject to change from
time to time based on changes In an Independent Index, which is the Interest
Rate on certain Time Certificates of Deposit Issued by Lender (the "Index"). The
Index is not necessarily the lowest rate charged by Lender on its loans. If the
Index becomes unavailable during the term of this loan, Lender may designate a
substitute Index after notice to Borrower. Lender will tell Borrower the current
Index rate upon Borrower's request. Borrower understands that Lender may make
loans based on other rates as well. The Interest rate change will not occur more
often than each 30 days. The Index currently is 5.070% per annum. The Interest
rate to be applied to the unpaid principal balance of this Note will be at a
rate of 1.250 percentage points over the Index, resulting In an Initial rate of
6.320% per annum. NOTICE: Under no circumstances will the interest rate on this
Note be more than the maximum rate allowed by applicable law.

PREFPAYMENT. Borrower may pay without penalty all or a portion of the amount
owed earlier than it is due. Early payments will not, unless agreed to by Lender
in writing, relieve Borrower of Borrower's obligation to continue to make
payments of accrued unpaid Interest. Rather, they will reduce the principal
balance due.

DEFAULT. Borrower will be In default if any of the following happens: (a)
Borrower fails to make any payment when due. (b) Borrower breaks any promise
Borrower has made to Lender, or Borrower fails to comply with or to perform when
due any other term, obligation, covenant, or condition contained In this Note or
any agreement related to this Note, or In any other agreement or loan Borrower
has with Lender. (c) Any representation or statement made or furnished to Lender
by Borrower or on Borrower's behalf is false or misleading in any material
respect either now or at the time made or furnished. (d) Borrower becomes
Insolvent, a receiver Is appointed for any part of Borrower's property, Borrower
makes an assignment for the benefit of creditors, or any proceeding Is commenced
either by Borrower or against Borrower under any bankruptcy or Insolvency laws.
(e) Any creditor tries to take any of Borrower's property on or in which Lender
has a lien or security Interest. This includes a garnishment of any of

                                      F-1

<PAGE>

Borrower's accounts with Lender. (f) Any guarantor dies or anyf of the other
events described in this default section occurs with respect to any guarantor of
this Note. (g) A material adverse change occurs in Borrower's financial
condition, or Lender believes the prospect of payment or performance of the
Indebtedness Is Impaired. (h) Lender in good faith deems Itself Insecure.

If any default, other than a default In payment; is curable and if Borrower has
not been given a notice of a breach of the same provision of this Note within
the preceding twelve (12) months, it may be cured (and no event of default will
have occurred) if Borrower, after receiving written notice from Lender demanding
cure of such default: (a) cures the default within fifteen (15) days; or (b) if
the cure requires more than fifteen (15) days, immediately initiates steps which
Lender deems in Lenders sole discretion to be sufficient to cure the default and
thereafter continues and completes all reasonable and necessary steps sufficient
to produce compliance as soon as reasonably practical.

LENDER'S RIGHTS. Upon default, Lender may declare the entire unpaid principal
balance on this Note and all accrued unpaid Interest immediately due, without
notice, and then Borrower will pay that amount. Upon default, Including failure
to pay upon final maturity, Lender, at its option, may also, if permitted under
applicable law, Increase the variable Interest rate on this Note to 4.250
percentage points over the Index. The interest rate will not exceed the maximum
rate permitted by applicable law. Lender may hire or pay someone else to help
collect this Note if Borrower does not pay. Borrower also will pay Lender that
amount. This includes, subject to any limits under applicable law, Lender's
attorneys' fees and Lender's legal expenses whether or not there is a lawsuit,

                    THIS LEASE ("Lease") is made and entered into as of the 30th
day of December, 1999, by and between WASECA PROPERTIES, LLC, a Minnesota
limited liability company ("Landlord"), and TRANSCRYPT INTERNATIONAL, INC., a
Delaware corporation ("Tenant").

RECITALS
--------
         A. Landlord is the owner of certain improved real property located
at 299 Johnson Avenue, Waseca, Minnesota, legally described on Exhibit A
attached hereto ("Entire Premises").

         B. The Entire Premises is improved with a building of approximately
246,924 square feet, which building consists of several rentable areas, Common
Areas, and Shared Areas, all as depicted on Exhibit B, attached hereto. The
Entire Premises is also improved with a driveway area, including areas for
loading and unloading trucks, and parking for occupants of the building and
their employees, invitees and licensees.

         C. Landlord, on even date herewith, purchased the Entire Premises from
Tenant, and such transaction was completed on the condition that Landlord and
Tenant would enter into this Lease for some of the rentable area of the building
previously occupied by Tenant.

         D. In addition to the Lease as described herein, the Entire Premises is
currently subject to certain other leases with Johnson Components, Inc., Data
Radio, formerly known as Johnson Data Telemetry Corporation, and Diversified
Credit Union. There is also other rentable area that is not subject to any lease
at this time.

AGREEMENT
---------
                    NOW, THEREFORE, for good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged by Landlord and Tenant,
Landlord and Tenant hereby covenant and agree as follows:

          1.      RECITALS. The Recitals are incorporated herein for all
purposes.

          2.      PREMISES. The Premises subject to this Lease are depicted
on Exhibit B attached hereto which Premises consist, for purposes of this
Lease, of 122,164 square feet. In addition to leasing the Premises, Landlord
hereby grants to Tenant its employees, invitees, licensees and other visitors
the right to use the Common Areas ("Common Areas") of the Entire Premises
including without limitation (a) sidewalks and lobby; (b) the main entrance
of the Entire Premises; (c) the parking lot area within the Entire Premises
for use by Tenant, its employees, visitors and agents; (d) loading dock areas
for loading and unloading trucks; (e) exclusive rights to use the parking
areas as designated on Exhibit C; and (f) the areas designated as Common
Areas on EXHIBIT B WHICH ARE IN THE BUILDING. Such right to use is granted to
the Tenant on the condition the Tenant conforms to and obeys such reasonable
rules and regulations concerning the Tenant's use of the Common Areas in
conjunction with the rights granted as such reasonable rules and regulations
may be promulgated (and with reasonable notice to Tenant, changed from time
to time) by Landlord, provided that such rules are uniformly applied to all
tenants and are not in conflict with this Lease. Except for the
aforementioned rights, the Tenant is not deemed to be in control or
possession of the Common Areas. Finally, Tenant has the right to use some
Shared Areas as depicted on Exhibit B which consists of Areas E through BB
("Shared Areas"). For purposes of determining Base Rent as defined below and
certain other costs and expenses all as set forth below, 53.2% of the Common
Areas, or 1985 square feet and 11,729 square feet of the Shared Areas will be
added to the square footage of the Premises. The square footage of Shared
Areas added herein is by agreement of Landlord and Tenant based on the
equitable use of such areas by Tenant at the present time. Landlord and
Tenant agree that such square footage cannot increase, but Landlord
acknowledges that it will make all reasonable efforts to acquire tenants for
rentable but currently unrented space in the building, or when the terms of
other leases expires to replace such tenants with tenants that will use the
Shared Area so that the square footage of the

                                       G-3

<PAGE>

Shared Areas assigned to Tenant hereunder shall decrease over the term of
this Lease. Such decrease shall occur at such time as there is a change in
the use allocation of the Shared Areas. Landlord shall have the right upon
reasonable notice (no less than 3 months) to Tenant to terminate the use of
part or all of the mezzanine as Shared Areas for use by Tenant and others to
provide expansion space to another tenant, Data Radio. At all times, Tenant
will be provided with a minimum of 2,500 square feet for a shared Lunchroom
Area with Kitchen with such area either in its current location or at some
other location in the building but adjacent to the Premises. Any and all work
required in connection with such change will be paid by Landlord and there
would be an appropriate reduction in the square footage assigned to Tenant
for Shared Areas. In addition, Landlord reserves the right to reduce the size
of the Common Areas to provide Data Radio with expansion space. If this
occurs there will be an appropriate adjustment in the number of square feet
of Common Areas assigned to Tenant hereunder. Adding together the square
footage of the Premises, the Common Area and the Shared Area, the total
square footage of the Premises, as of the date hereof, is 135,878 square feet.

                  In addition to the rights described above, Tenant will have
the exclusive right to use the tower(s) located on the Entire Premises for
its exclusive use; the FCC Site located on the Entire Premises for its
exclusive use; and all antennae and related equipment located on the building
for its exclusive use. These uses are all at no additional cost to Tenant.

                  In addition, Tenant will have the right to use Area 2 as
identified on EXHIBIT B-1 attached hereto for purposes of temporary storage
for 2 months at no additional cost or rent to Tenant.

          3.      TERM AND RENEWAL

                  a. The term of this Lease ("Term") is for a period of five (5)
years commencing on January 1, 2000 (the "Commencement Date") and ending on
December 31, 2004.

                  b. Tenant shall have the option to renew the Lease for an
additional five (5) year period at the greater of Base Rent as defined at
Paragraph 5 below $3.00 per square foot in the Premises or the market rate for
base rent in the Waseca, Minnesota area prevailing at the time of the
commencement of the renewal Term. Tenant agrees to notify Landlord at least six
(6) months prior to the end of the Term of the Lease if it wishes to renew for
the additional five (5) year period. If Tenant exercises the renewal option,
then at least five (5) months prior to the expiration of the initial Term,
Landlord and Tenant shall meet and attempt to come to an agreement as to the
current fair market value for the Premises. If Landlord and Tenant have not
reached agreement on the prevailing market rental rate at least four (4) months
prior to the expiration of the initial Term, then Landlord and Tenant shall each
select a real estate broker having no less than seven (7) years experience in
commercial leasing in the Waseca, Minnesota area. Those two brokers will then
meet (at least two (2) months prior to the expiration of the initial Term) to
determine the prevailing market rental rate and if they cannot reach agreement
on the prevailing market rental rate, then each broker will pick a third broker,
who shall make its determination (at least one (1) month prior to the expiration
of the initial Term) of the prevailing market rental rate. The Base Rent for the
renewal Term shall be the average of the two brokers' determinations that are
closest to each other. If the market rental rate is greater than $3.00 per
square foot in the Premises, Tenant, upon notification of such market rate, can
elect to rescind its notification as to the renewal Term and in such event, this
Lease will terminate as of the end of the Term. If and only if the Lease is
renewed the renewal Term will, for all purposes, be considered part of the Term.
Landlord and Tenant agree that the Lease is to remain in effect for six (6)
months after Tenant's notice of rescission is given and the Base Rent during
such six (6) month period shall be at the current Base Rent. To the extent that
this six (6) month period extends the initial Term, the parties agree that such
Term shall be so extended and Tenant will not be deemed to be holding over and
all of the other terms and conditions of this Lease applicable to the initial
Term shall apply.

          4.      BASE RENT

                  a. The total annual rental (herein called "Base Rent") for the
Premises shall be Three and 00/100 Dollars ($3.00) per square foot in the
Premises which is determined to include the Premises and 1,185 square feet of
Common Areas and 11,729 square feet of Shared Area so that the total

                                       G-4

<PAGE>

annual base rent is $3.00 multiplied by 135,878 square feet, which equals
$407,634.00. The Base Rent will be paid in monthly installments of $33,970.00.
Any change in the Base Rent because of the change in the size of the Premises,
the Common Areas or the Shared Areas must be approved by both parties and be the
subject of a written amendment executed by both parties. Landlord acknowledges
that it has the obligation hereunder to use all reasonable efforts to decrease
the square footage of the Shared Areas assigned to Tenant under this Lease. All
monthly payments of Base Rent will be paid in advance, on the first day of each
and every calendar month during the Term.

                  b. All additional sums of money, other than Base Rent, if any,
which become due under this Lease (the "Additional Rent") together with the Base
Rent are referred to as "Rent". All Rent due or to become due hereunder shall be
paid to Landlord at Waseca Properties, LLC, 1224 West 96th Street, Bloomington,
Minnesota 55431, Attn: Jay, or at such other place as Landlord shall designate
by giving written notice to that effect to Tenant.

         5.       ADDITIONAL RENT

         Tenant shall pay to Landlord Tenant's Share of certain expenses as
described below. For purposes of this Lease, Tenant's Share means 55.1% of
certain costs which percentage is based on a ratio in which the numerator is the
number of square feet in the Premises and the Shared Areas assigned to Tenant
and the denominator is the number of total square feet in the Entire Premises
less the total Common Areas including areas exclusively used by Landlord. The
sum of all tenant's shares including Landlord for unrented but rentable areas
will equal 100%. As described below, Tenant's Share shall be modified if it is
more appropriate to charge Tenant for actual costs for some services. Tenant's
Share will be changed if either the numerator or the denominator changes.
However, Landlord cannot decrease the denominator without Tenant's consent if
such decrease results in the Tenant's Share percentage being increased.
Additional Rent shall be paid for certain costs as follows:

                  a. Tenant shall pay within 30 days of receipt of notice
Tenant's Share of the Real Estate taxes. The notice provided by Landlord shall
include a copy of the applicable tax statement. The term "Real Estate Taxes"
shall mean all real estate taxes, all special assessments and any taxes in lieu
thereof which may be levied upon or assessed against the Entire Premises of
which the Premises are a part, excluding interest and penalties from the late
payment or nonpayment of real estate taxes by Landlord. Tenant, in addition to
all other payments to Landlord by Tenant required hereunder shall pay to
Landlord, in each year during the term of this Lease, Tenant's Share of such
real estate taxes and assessments paid in the first instance by Landlord.

                  Any tax year commencing during any calendar year shall be
deemed to correspond to such calendar year. In the event the taxing authorities
include in such real estate taxes and assessments the value of any improvements
made by Tenant, or of machinery, equipment, fixtures, inventory or other
personal property or assets of Tenant, then Tenant shall pay all the taxes
attributable to such items in addition to its share of said aforementioned real
estate taxes and assessments. A photostatic copy of the tax statement submitted
by Landlord to Tenant shall be sufficient evidence of the amount of taxes and
assessments assessed or levied against the Entire Premises of which the Premises
are a part.

                  b. A sum equal to Tenant's Share of the annual aggregate
operating expenses incurred by Landlord in the operation, maintenance, repair
and cleaning of the Entire Premises. The term "Operating Expenses" shall include
but not be limited to all utilities including gas, oil, electricity, water and
sewer, building maintenance, Premises cleaning, changing light bulbs, repair,
replacement and care of all Common Area lighting, Common Area plumbing, and
landscaping, parking and landscaped areas, signs, snow removal, non-structural
repair and maintenance of the roofs and exterior of the Building, insurance
premiums, management fee, wages and fringe benefits of personnel employed or
contracted for such work and costs of equipment purchased and used for such
purposes. Tenant shall be solely responsible for any capital improvements made
by Landlord which are solely required by Tenant's particular and unique use of
the Premises. Notwithstanding the above, Landlord acknowledges that Landlord
will be responsible for the cost of any improvements in connection with moving
the "Staging Area" and the Tenant will pay none of

                                       G-5

<PAGE>

such costs, except Tenant will have the right to move all of its Tenant
Equipment and Fixtures to a new Staging Area within the Premises capable of
being moved and Tenant will pay for the costs of moving such Equipment and
Fixtures. In addition, if such Staging Area is not moved by Landlord within the
first 3 months of the Term, then Landlord can move such Staging Area only upon 4
months notice to Tenant in advance of such work. Tenant will provide basic plans
and specifications for the new "Staging Area" by January 14, 2000. Landlord's
expenditures for capital improvements which are permitted to be capitalized
shall only be included as operating expenses to the extent of depreciation
allowable for tax purposes in such year. Maintenance, repair and installation of
Tenant's special equipment will be billed directly. Levels of maintenance and
cleaning shall match levels in place under the Tenant's occupancy which precedes
this Lease.

                  c. Tenant shall pay Tenant's Share of Operating Expenses
monthly based upon Landlord's estimate of such expenses. Prior to commencement
of this Lease and prior to the commencement of each calendar year thereafter
commencing during the term of this Lease or any renewal or extension thereof,
Landlord shall estimate for each calendar year (i) the total amount of Operating
Expenses, (ii) Tenant's Share of Operating Expenses for such calendar year; and
(iii) the computation of the monthly additional rent payable during such
calendar year. Said estimates will be in writing and will be delivered or mailed
to Tenant. The amount of Tenant's Share of Operating Expenses for each calendar
year, so estimated, shall be payable as Additional Rent, in equal monthly
installments, in advance, on the first day of each month during such calendar
year. In the event that such estimate is delivered to Tenant before the first
day of January of such calendar year, said amount, so estimated, shall be
payable as Additional Rent in equal monthly installments, in advance on the
first day of each month during such calendar year. In the event that such
estimate is delivered to Tenant after the first day of January of such calendar
year, said amount, so estimated, shall be payable as Additional Rent in equal
monthly installments, in advance, on the first day of each month over the
balance of such calendar year, with the number of installments being equal to
the number of full lease months remaining in such calendar year. The monthly
payments of Additional Rent required hereunder for the calendar year beginning
January 1, 2000 will be based on the 1999 estimate of operating expenses and
Landlord will prepare an estimate for calendar year 2000 by no later than
February 29, 1999 and when such estimate has been completed, appropriate
adjustments between Landlord and Tenant will be made in connection with the
payments made by Tenant for the first two months of the Term.

                  d. Upon completion of each calendar year during the term of
this Lease, or any renewal or extension thereof, Landlord shall cause its
accountants to determine the actual amount of the Operating Expenses payable in
the just completed calendar year and Tenant's Share thereof and deliver a
statement of the amounts thereof to Tenant. If Tenant has underpaid its share of
Operating Expenses for such calendar year, Tenant shall pay the balance of its
share of same within thirty (30) days after the receipt of such statement. If
Tenant has overpaid its share of Operating Expenses for such calendar year,
Landlord shall either (i) refund such excess, or (ii) credit such excess against
the most current monthly installment or installments due Landlord for its
estimate of Tenant's Share of Operating Expenses for the then current calendar
year. A pro rata adjustment shall be made for a fractional calendar year
occurring during the term of this Lease, except for the first year, or any
renewal or extension thereof based upon the number of days of the term of the
Lease during said calendar year as compared to three hundred sixty-five (365)
days and all additional sums payable by Tenant or credits due Tenant as a result
of the provisions of this Paragraph 5 shall be adjusted accordingly. Landlord
reserves the right to separately meter Tenant's space or to otherwise modernize
the utilities in order to reduce operating costs. Tenant will pay Landlord
Tenant's Share of expenditures, of an approximately Thirty-one Thousand Dollars
($31,000) amount for Geo-Thermal System improvement for Teratherm, cooling tower
controls and chiller efficiency improvement as set forth on EXHIBIT D. Tenant
agrees to pay its Tenant's Share of such expenditures, with payment to be made
within 30 days of receipt of a statement for such amount from Landlord so long
as such work is completed by September 30, 2000.

                  e. If appropriate, Tenant's Share of certain Operating
Expenses shall be calculated based on the best objective estimate of actual
usage. Categories of Operating Expenses (Common Area and direct) are set forth
on EXHIBIT E. Current and projected Operating Expenses for all tenants are set
forth on EXHIBIT E-1 attached hereto. Current and projected Operating Expenses
for Tenant are set forth on EXHIBIT F.

                                       G-6

<PAGE>

Appropriate adjustment will be made to reflect actual costs associated with
different actual usage such as fewer or more shifts and weekend usage which
shall take into account whether other Tenants also are operating at that time
and whether costs are higher or lower such as for weekend or holiday overtime.
Appropriate adjustments also shall be made to reflect actual costs associated
with particular operations of a Tenant which result in cost savings or
additional costs. The parties agree that the allocations will be adjusted
annually to reflect actual usage, including additional work days, more or fewer
shifts and other changes in usage. The parties acknowledge and agree that the
term Operating Expenses is intended to cover all services provided to Tenant by
Landlord, including CAM (Common Area Maintenance), and that the amount charged
shall be increased by the Tenant's Share of any additional services discovered
or initiated by the parties and shall be reduced proportionately for any
services terminated by the Tenant. CAM shall include the following items:
Maintenance of Central Heating and Cooling Plant, Pest Control, Exterior
Repairs, Snow Plowing, Landscaping, Roof Repairs, Parking Lot Maintenance,
Exterior Lighting, Structural Repairs, Cleaning and Maintenance of Lobby and
Other Common Areas, Common Signage, Common Area Fire Extinguishers, Window
Washing, Fire Sprinkler System Maintenance, Common Area Utilities, Cleaning,
Maintenance, Paper Supplies, Heating and Cooling.

                  f. Tenant shall have the right at its sole expense to audit
the Operating Expenses and the allocation of Tenant's Share. Tenant shall notify
Landlord in writing of any disagreement with the calculation of Tenant's Share
of the items included in Operating Expenses. If Landlord and Tenant are not able
to reach agreement with respect to any such disputed matter, Tenant shall be
entitled to refer the disputed matter to binding arbitration pursuant to
Paragraph 35 below.

         5A.      OPERATING EXPENSES EXCLUSIONS

rent for management or leasing offices;

                  g. COSTS OTHERWISE RECOVERED. The cost of any items for which

or Building which would be considered an Operating Expense (subject to the
exceptions specified above) (hereinafter "Capital Replacement"), and if, under
generally accepted accounting principles, such expenditure is not a current
expense, then the cost shall be amortized over a period equal to the useful life
of such Capital Replacement, determined in accordance with generally accepted
accounting principles, and the amortized costs allocated to each calendar year
during the Term shall be treated as an operating expense.

         6. UTILITIES AND SERVICES

                     Landlord shall perform and or provide all the services as
described in paragraph 5b. above, including, but not limited to, reasonable
water, electrical service and functioning air compressor, janitorial service
under specifications as determined from time to time between the parties,
security as determined from time to time between the parties, and heating,
ventilating and air-conditioning to the Premises. Landlord acknowledges that
because of Tenant's use of the Premises, Landlord's failure to provide all such
services, including, but not limited to, the unavailability of water, electrical
service, HVAC and an air compressor for even a short period of time will have
serious impact on Tenant's ability to operate its business in the Premises.
Therefore upon notification from Tenant of any problem with such utilities or
services, Landlord will reasonably respond. If Landlord through an agent or
otherwise has not responded within a reasonable period, Tenant will have the
right, but not the obligation, to engage a professional or consultant to remedy
the problem and any costs of such professional or consultant shall be paid by
Landlord and included as an Operating Expense. If Landlord fails to pay such
consultant in a timely manner, Tenant can make such payment and deduct such
payment along with a fee of 5 percent of such cost from the Rent due and payable
to Landlord for the next monthly installment and all subsequent monthly
installments until the Tenant has been reimbursed in full. In addition, if
Landlord or any agent or consultant (regardless of which party engaged the agent
or consultant) does not or cannot remedy the problem within 2 days of the
occurrence, and such problem materially impacts the Tenant's ability to run its
business, Tenant's obligation to pay Rent shall abate for each day that the
problem exists until such problem has been remedied. Landlord and Tenant agree
that they will use their best

                                       G-8

<PAGE>

efforts to establish a preapproved list of professionals and/or consultants to
provide the services required hereunder to minimize the potential of a delay in
resolving any problems.

         7. MAINTENANCE AND REPAIRS

                  Tenant shall, at all times throughout the term of this Lease,
keep and maintain the Premises in a clean, safe, sanitary and condition
consistent with the condition the Premises were delivered to Tenant and in
compliance with all applicable laws, codes, ordinances, rules and regulations,
subject to any available "grandfathering" to the extent that Landlord is not
otherwise obligated to maintain the Premises hereunder. Tenant's obligations
hereunder shall include but not be limited to paying their share of the
maintenance, repair and replacement, if necessary, of heating and air
conditioning fixtures, equipment, and systems, all lighting and plumbing
fixtures and equipment, other fixtures, motors and machinery, all interior
walls, partitions, doors and windows, including the regular painting thereof,
all exterior entrances, windows, doors and docks and the replacement of all
broken glass. Service levels provided by Landlord upon this Agreement shall
match the levels provided under the occupancy by Tenant which precedes this
Lease with this exception that maintenance and repair of Tenant's equipment will
only be provided subject to an additional charge to be determined by the Parties
under a separate agreement. Notwithstanding the above, Landlord shall be
responsible for maintaining the central heating and cooling plant and shall
maintain electrical distribution equipment to the Premises and replacement, if
necessary, of major components of the heating and cooling plant, building
electrical system and building plumbing system such as building piping. When
used in this provision, the term "repairs" shall include replacement or renewals
when necessary, and all such repairs made by the Landlord shall be no less than
equal in quality and class to the original work. The Tenant shall keep and
maintain all portions of the Premises in a clean and orderly condition, free of
accumulation of dirt and rubbish. Tenant's obligations under this Paragraph 7
are subject to damage by casualty to the extent covered by Landlord's insurance
and condemnation.

                    If Tenant fails, refuses or neglects to maintain or repair
the Premises as required in this Lease after notice shall have been given
Tenant, Landlord may make such repairs without liability to Tenant for any loss
or damage that may accrue to Tenant's merchandise, fixtures or other property or
to Tenant's business by reason thereof, provided Landlord exercises reasonable
care, and upon completion thereof, Tenant shall pay to Landlord all costs
incurred by Landlord in making such repairs upon presentation to Tenant of bill
therefor.

                    Landlord shall repair, at its expense, the structural
portions of the Building, provided however where structural repairs are required
to be made by reason of the negligence or willful misconduct of Tenant and not
covered by insurance, required hereunder whether or not in force the costs
thereof shall be borne by Tenant and payable by Tenant to Landlord upon demand.

                    The Landlord shall be responsible for all outside
maintenance of the Common Areas of the Premises, including landscaping grounds
and parking areas. All such maintenance which is the responsibility of the
Landlord shall be provided as reasonably necessary to the comfortable use and
occupancy of Premises during business hours, except Saturdays, Sundays and
holidays, upon the condition that the Landlord shall not be liable for damages
for failure to do so due to causes beyond its control.

                    Notwithstanding anything to the contrary, this Paragraph 7
does not require Tenant to put or maintain the Premises in a condition better
than the condition as of the date of the Lease.

         8. ALTERATIONS AND LEASEHOLD IMPROVEMENTS

                    a. Without Landlord's prior written consent (which consent
shall not be unreasonably withheld), Tenant will not make any alterations,
installations, modifications or additions to the Premises (hereinafter
collectively called "Alterations") which affect the structural integrity of the
Premises or which affect the roof or adversely affect the mechanical or
electrical systems (collectively "Structural Alterations"). All such work shall
be done in a good and workmanlike manner and in accordance with all applicable
laws. Tenant shall provide lien waivers to Landlord covering all contractors
and/or subcontractors that provide labor and materials during alteration.

                                       G-9

<PAGE>

                  b. All leasehold improvements shall be at Tenant's sole cost
and expenses, with Landlord's prior written approval. All leasehold improvements
shall be made by a licensed, bonded and insured contractor and Tenant shall
provide Landlord with lien waivers upon completion of any work.

                  the business operated by Tenant thereon, and including
                  contractual liability coverage for Tenant's insurable
                  indemnity obligations under this Lease (other than those

                  minimum combined single limit of liability of at least One

                           (ii) Such policies will be maintained in financially
                  reputable companies duly licensed in the State of Minnesota,

                  occur of (a) the Commencement Date of this Lease, or (b)
                  Tenant's occupancy of the Premises, which certificates or
                  other evidence shall contain a provision stating that such
                  policy or policies shall not be canceled or materially altered
                  with respect to the Premises except after thirty (30) days'
                  written notice to Landlord. Tenant shall have the right to
                  provide the coverage required hereunder under blanket
                  policies. Landlord will be named as an Additional Insured
                  and/or Loss Payee in any such policies.

                  (iii) All furnishings, fixtures, equipment, and property of
every kind and description of Tenant and of persons claiming by or through
Tenant which may be on the Premises shall be at the sole risk and hazard of
Tenant and no part of loss or damage thereto for whatever cause is to be charged
to or borne by Landlord.

                  b. Landlord's Insurance.

                  (i) Landlord, at its sole cost and expense, shall obtain and
maintain in effect so long as this Lease remains in effect, general liability
insurance, in occurrence form, insuring Landlord against any and all liability

risks or hazards now or hereafter embraced by an "Extended Coverage
Endorsement", (cc) loss for flood if the Entire Premises are in a designated

other risks as a reasonably prudent owner of similarly situated properties
similar to the Entire Premises would normally insure against, such insurance to
provide for the payment of full replacement cost in the event of a total
destruction of the Entire Premises so as to ensure the availability of
sufficient funds to repair and restore the Entire Premises to its condition
immediately prior to any damage or destruction; and

                                      G-10

<PAGE>

                  (iii) To the extent that Landlord has any employees who enter
the Premises to perform any work or provide any services thereon, Landlord shall
also, at its sole cost and expense, maintain workers' compensation and similar

which Tenant shall carry. Landlord shall deposit certificates of such required
insurance with Tenant prior to the earlier to occur of (a) the Commencement Date

other evidence shall contain a provision stating that such policy or policies
shall not be canceled or materially altered with respect to the Premises except
after thirty (30) days' written notice to Tenant. Landlord shall have the right

other or to any insurance company insuring the other party (by way of
subrogation or otherwise) for any loss or damage to any structure, building, or
other tangible property, or any resulting loss of income, even though such
damage or loss might have been occasioned by the negligence of Landlord or
Tenant or any of their agents or employees, if any such loss or damage is
covered by insurance benefiting the party suffering such loss or damage or was
required of such party to be covered by insurance pursuant to this Lease. Except
to the extent that the provisions of Paragraph 13 are applicable, this waiver
covers deductibles as well, i.e., the insured party is liable for any and all
deductibles in its insurance policies and it shall not be entitled to any
payment or reimbursement thereof, except, a reasonable deductible amount for
casualty insurance can be included as an Operating Expense so long as such
deductible amount is included for all tenants.

                  d. Indemnity

                                    Except if and to the extent that such party

                  costs, fees and expenses connected therewith or incident
                  thereto) arising out of Landlord's breach of this Lease or the
                  negligent or unlawful act or omission or willful misconduct of
                  Landlord, its officers, partners, employees, agents or
                  contractors as it relates to the Premises; and

                           (ii) Tenant does hereby assume liability for, and
                  does hereby agree to indemnify, protect, defend, save and hold
                  harmless Landlord its officers, directors, agents and

                  judgments, penalties, damages and losses (including all of the
                  costs, fees and expenses connected therewith or incident
                  thereto) Tenant's breach of this Lease or arising out of the
                  negligent or unlawful act or omission or willful misconduct of
                  Tenant, its officers, employees, agents or contractors as they
                  relate to Tenant's use and/or occupancy of the Premises.

         10.      ASSIGNMENT AND SUBLETTING

    Tenant shall not assign this Lease or sublet all or any part of the Premises
without the prior written consent of Landlord, which consent shall not be
unreasonably withheld, conditioned or delayed if the proposed assignee or
subtenant is of equal or greater creditworthiness than Tenant and the use is not

                                      G-11

<PAGE>

incompatible with the Building. Notwithstanding the foregoing, however, Tenant
may assign or sublet this Lease, without Landlord's prior written consent, to
any corporation or other entity which controls Tenant, which Tenant controls or
is directly or indirectly controlled by or under common control with Tenant or
merges with Tenant. If Tenant shall assign this Lease or any part thereof,
Tenant shall be released from responsibilities for all Tenant obligations under
the Lease, if such obligations are assumed by assignee in writing.

         11.      SUBORDINATION

                  Tenant agrees upon request of Landlord to subordinate this
Lease and its rights hereunder (excluding Tenant's rights to the use and
application of insurance and condemnation proceeds as set forth in this Lease)
to the lien of any mortgage, deed of trust or other voluntary hypothecation
arising out of any security instrument duly executed by Landlord charged against
the Premises, or any portion or portions thereof, and to execute at any time and
from time-to-time such documents as may be reasonably required to effectuate
such subordination; provided, however, that Tenant shall not be required to
effectuate any such subordination or other document hypothecating any interest
in the Premises unless the mortgagee or beneficiary named in such mortgage or
deed of trust shall first enter into a Subordination, Non-Disturbance and
Attornment Agreement in such form and content substantially similar to that
attached as EXHIBIT H and if there is or will be, as of the Commencement Date of
this Lease, any mortgage in effect with respect to the Premises, or any portion
or portions thereof, which would thereby be superior to this Lease, Landlord
shall obtain and deliver to Tenant, prior to the Commencement Date of this
Lease, a Subordination Non-Disturbance and Attornment Agreement in such form and
content substantially similar to that attached as EXHIBIT H duly executed on
behalf of each such lessor, mortgagee and beneficiary.

         12.      DAMAGE AND DESTRUCTION

                  a. If the Premises should be damaged or destroyed by fire,
tornado or other casualty, Tenant shall give immediate written notice thereof to
Landlord.

                  b. If the Premises should be totally destroyed by fire,
tornado or other casualty, or if it should be so damaged thereby that rebuilding
or repairing the Premises to substantially the same condition, as immediately
prior to such damage, cannot (in the reasonable estimation of Tenant's architect
or contractor) be completed within ninety (90) days after the date upon which
Landlord is notified by Tenant of such damage, or are not substantially
completed within said ninety (90) days, then Tenant may, at its option,
terminate this Lease effective upon the date of the occurrence of such damage.
In such case, all insurance proceeds payable incidental thereto shall be
retained by Landlord.

                  c. If the Premises should be damaged by any peril covered by
the insurance to be provided by Landlord pursuant to the provisions of this
Lease, and rebuilding of or repairs to the Premises to substantially the same
condition as immediately prior to such damage can (in the reasonable estimation
of Landlord's architect or contractor) be completed within ninety (90) days
after the date upon which Landlord is notified by Tenant of such damage or if
Tenant elects not to terminate this Lease as provided in Paragraph 12.b,
Landlord will proceed with reasonable diligence to rebuild and repair the
Premises to substantially the condition in which it existed immediately prior to
such damage, except that Landlord will not be required to rebuild, repair or
replace any part of the partitions, fixtures, additions and other improvements
which may have been placed in, on or about the Premises by Tenant. The Rent
payable hereunder shall be equitably abated from the date of damage or
destruction in the proportion and to the extent that the Premises are unusable
by Tenant for Tenant's Intended Use.

         13.      CONDEMNATION

                  a. If, during the Term of this Lease, the Entire Premises
shall be taken for any public or quasi-public use as the result of the exercise
of the power of eminent domain or by sale in lieu of eminent domain (hereinafter
referred to as the "Proceedings"), this Lease shall terminate upon vesting of
title in the Proceedings and any prepaid Rent and other prepaid charges paid by
Tenant to Landlord shall be refunded to Tenant.

                                      G-12

<PAGE>

                  b. If, during the Term of this Lease, or any extension or
renewal thereof, less than the Entire Premises shall be taken in any such
Proceedings, this Lease will, upon vesting of title in the Proceedings,
terminate as to the portion of the Premises so taken, Tenant may, at its option,
terminate this Lease as to the remainder of the Premises. Such termination shall
be effected by notice in writing given not more than sixty (60) days after the
date of vesting of title in such Proceedings, and shall specify a date not more
than sixty (60) days after the giving of such notice as the date for such
termination.

                  c. If a taking as described in Subparagraph 13.b occurs and
this Lease is not terminated as described therein, this Lease will, upon vesting
of title in the Proceedings, terminate as to the parts so taken but shall
continue in full force and effect as to that portion of the Premises remaining,
and Landlord shall, at Landlord's cost, diligently pursue the restoration of the
remaining Premises so that they are as closely as possible to their condition
immediately prior to the taking by eminent domain, and shall use the amount of
the condemnation proceeds received by Landlord ("Landlord's Condemnation Award")
therefor.

                  d. In no event shall Landlord be required to repair or
replace: (i) Tenant's personal property such as wall coverings, carpeting, and
window treatments merchandise (except to the extent Landlord's Condemnation
Award contains an amount allocated for reimbursement for such personal
property); or (ii) Tenant's furnishings, operating equipment, trade fixtures, or
merchandise (except to the extent Landlord's Condemnation Award contains an
amount allocated for reimbursement for such personal property).

                  e. In the event of any termination of this Lease, or any part
thereof, as a result of any such Proceedings, Tenant shall pay to Landlord Rent
payable hereunder with respect to that portion of the Premises as taken in such
Proceedings justly apportioned to the date of such termination. If this Lease
continues as to that portion of the Premises not taken, Tenant shall continue to
pay the Rent payable hereunder, as in this Lease provided, subject to an
abatement of a just and proportionate part of the Rent payable hereunder
according to the extent and nature of such taking.

                  f. Landlord shall at all times keep Tenant fully advised of
any Proceedings or threat thereof. Any award or compensation arising out of such
taking shall belong to and be paid to Landlord except with respect to any
separate award made to Tenant for its leasehold improvements and fixtures,
relocation expenses and other damages or costs pursuant to a separate
independent action taken by Tenant against the condemning authority.

         14.      ACCESS

    Landlord's agents, employees, contractors, prospective purchasers, existing
and prospective mortgagees and, during the last six (6) months of the Term (as
the same may have been extended), prospective tenants, shall have the right to
enter the Premises at reasonable times with prior reasonable notice to Tenant
for the purpose of inspecting the same; provided, however, any such party
entering upon the Premises shall cause as little inconvenience, annoyance and
disturbance to Tenant as may be reasonably possible under the circumstances and
shall comply with all reasonable security regulations and procedures as may then
be in effect with respect to Tenant's operations on the Premises. Tenant may
require that an employee or agent be present at any inspection or other entry of
the Premises by Landlord or its agents (except in the case of an emergency).

         15.      DEFAULT BY TENANT

                  If Tenant at any time during the Term of this Lease shall:

                  a. Default in the payment of any installment of Rent or any
other sum specifically to be paid by Tenant hereunder and such default shall not
have been cured within fifteen (15) days after Landlord shall have given to
Tenant written notice specifying such default; or

                                      G-13

<PAGE>

                  b. Default in the observance or performance of any of Tenant's
other covenants hereunder (other than the covenant to pay Rent or any other sum
herein specified to be paid by Tenant) and such default shall not have been
cured within thirty (30) days after Landlord shall have given to Tenant written
notice specifying such default; provided, however, that if the default
complained of shall be of such a nature that the same cannot be completely
remedied or cured within such thirty (30) day period, then such default shall
not be an enforceable default against Tenant for the purposes of this Paragraph
15 if Tenant shall have commenced curing such default within such period and
shall proceed with reasonable diligence and in good faith to remedy such default
complained; or

                  c. Finally, and without further possibility of appeal or
review, (i) be adjudicated bankrupt or insolvent, or (ii) have a receiver or
trustee appointed for all or substantially all of its business or assets on the
ground of Tenant's insolvency, or (iii) suffer an order to be entered approving
a petition filed against Tenant seeking reorganization of Tenant under the
Federal Bankruptcy Laws or any other applicable law or statute of the United
States or any State thereof; or

                  d. Make an assignment for the benefit of its creditors, or
file a voluntary petition in bankruptcy or a petition or answer seeking
reorganization or arrangement under the Federal Bankruptcy Laws or any other
applicable law or statute of the United States or any state thereof, or shall
file a petition to take advantage of any insolvency act or shall consent to the
appointment of a receiver or trustee, of all or a substantial part of its
business and property;

         15A.     LANDLORD REMEDIES

                  Upon the happening of any one or more of such events of
default and the expiration of the applicable period of time for curing such
default, Landlord may, without further notice to Tenant and without further
demand for Rent due or for the observance or performance of any of said terms,
conditions or agreements, elect to do one or more of the following: (a) perform,
on behalf and at the expense of Tenant, any obligation of Tenant under this
Lease which Tenant has failed to perform, the actual and reasonable cost of
which performance by Landlord shall be deemed Additional Rent and shall be
payable by Tenant to Landlord upon demand (together with interest thereon at a
rate of interest equal to eight percent (8%) per annum ("Default Rate"); (b)
terminate this Lease and re-enter said Premises and remove all persons and
property therefrom, using legal process as may be necessary, and recover the
cost thereof, and again possess said Premises as its own; or (c) exercise any
other right or remedy available to Landlord at law or in equity. In the event
Landlord re-enters the Premises and removes Tenant (if Tenant is still in
possession) from the Premises, regardless of whether or not Landlord shall have
terminated this Lease, Tenant will nevertheless remain liable for all Rent which
may then be due and which shall thereafter become due for the balance of the
Term less the fair rental value of the Premises for the balance of the Term with
such amount reduced to present value using a discount rate of 8%.

                  All monies due under this Lease from Tenant to Landlord shall
be due on demand, unless otherwise specified, and if not paid by the fifth day
of the month shall result in the imposition of a service charge for late payment
in the amount of ten percent (5%) of the amount due.

16.      ESTOPPEL CERTIFICATES

    Upon execution of this Lease, Tenant will execute and deliver a reasonable
Estoppel Certificate and Tenant shall, within twenty (20) days after written
request of Landlord, execute, acknowledge and deliver to Landlord or to
Landlord's mortgagee, proposed mortgagee, and lessor or proposed purchaser of
the Premises, any reasonable estoppel certificates requested by Landlord which
shall state whether this Lease is in full force and effect and whether any
changes may have been made to the original of this Lease; whether the term of
this Lease has commenced and full Rent is accruing; whether there are any
defaults by Landlord and, if so, the nature of such defaults; whether Tenant is
in possession of the Premises and all improvements to be provided by Landlord
have been completed; whether Rent has been paid more than thirty (30) days in
advance; whether there are any liens, charges, or offsets against Rent due or to
become due; and whether the address shown on such estoppel certificate is
accurate. Landlord agrees that, within twenty (20) days after written request of
Tenant, Landlord shall execute, acknowledge and deliver to

                                      G-14

<PAGE>

Tenant a similar certificate.

         17.      HOLDING OVER

    In the extent Tenant remains in possession of the Premises after the
expiration of the Term (except if Tenant remains in possession because Tenant
has given notice of renewing the Lease under paragraph 3b hereof and the fair
market rent for the renewal Term has not been established, or if Tenant rescinds
its notice renewing the Lease and the Lease is in the six (6) month extension
period as described in paragraph 3(b)) hereof, it shall be deemed to be a tenant
from month-to-month only, at one hundred twenty-five percent (125%) of the
monthly installment of Base Rent in effect during the last month of the expired
Term. Except as aforesaid, such tenancy shall be upon and subject to the terms
of this Lease. Either party may terminate such tenancy by giving to the other at
least thirty (30) days' prior written notice of its intent to terminate.

         18.      SURRENDER

to Landlord at the expiration of the Term in as good condition as on the
Commencement Date except for the following (a) ordinary wear and tear, (b)
Alterations not removed as permitted hereunder, (c) any appropriation or taking
under power of eminent domain or by paramount authority, (d) damage by fire or
other casualty, and (e) any condition arising or existing by reason of
Landlord's failure to repair or maintain the Premises as required of it
hereunder. Tenant will have the right to remove all Tenant fixtures and personal
property from the Premises so long as Tenant repairs, at Tenant's cost, all
damages to the Entire Premises caused by such removal.

         19.      NOTICES

    All notices, requests, demands or other communications with respect to this
Lease, whether or not herein expressly provided for, shall be in writing and

         20.       QUIET ENJOYMENT AND USE

    Landlord covenants and agrees that Tenant, so long as it shall not be in
default hereunder beyond any applicable cure period, shall and may, at all times
during the Term, peaceably and quietly have, hold, occupy and enjoy the Premises

Landlord acknowledges that Tenant can use the Premises for manufacturing,

its subsidiary corporations and investment entities (and each of their
subsidiary corporations and investment entities), predecessors and successors in
interest, assigns, subtenants, officers, directors, employees, managers,
attorneys, accountants, agents and servants, and each of them in all capacities
including, individually (collectively the "Tenant's Parties"), from and against
all claims, costs, damages (including, without limitation, any and all sums paid
for settlement of claims, attorneys' fees, consultant and expert fees and
consequential damages), fines, judgments, penalties, losses, liabilities and
expenses suffered or incurred by the Indemnified Parties, or any of them,
arising directly or indirectly out of or as a consequence of the actual or
suspected use, storage, handling, generation, transportation, manufacture,
production, release, discharge, disposal or presence of "Hazardous Substances"
(as hereinafter defined) on, in, under or about the Premises or the air, soil or
groundwater thereof not caused by Tenant, its employees, contractors or agents
based on an occurrence from and after the date of this Lease. Landlord's
indemnification shall expressly survive the expiration or earlier termination of
this Lease. Notwithstanding anything to the contrary that may be contained in
this Lease, Landlord's indemnification shall not include any consequential
damages (e.g., use and profits) incurred by Tenant, but shall expressly include,
without limitation, any and all costs incurred due to any investigation of the
site or any cleanup, removal or restoration mandated by or pursuant to any
Environmental Laws. Landlord's indemnification shall survive any expiration or
termination of the Term.

                  b. From and after the date of this Lease, Tenant shall not
cause or permit any Hazardous Substances to be used, stored, handled, generated,
transported, manufactured, produced, released, discharged or disposed of in, on
or about the Premises by Tenant, its agents, employees, contractors or invitees,
except for such Hazardous Substances as are commonly used in a manufacturing,
warehouse/office setting (such as normal quantities of substances like
pesticides; janitorial supplies, copier toner, etc., for example) or as are
normally utilized in the environment of Tenant's Intended Use and are necessary
to Tenant's business. Tenant shall provide Landlord with a list of all Hazardous
Substances permitted on the Premises and shall update such list for any
additional Hazardous Substances introduced on or about the Premises. Any such
Hazardous Substances permitted on the Premises as hereinabove provided, and all
containers therefor, shall be used, kept, stored and disposed of in a manner
that complies with all "Environmental Laws" (as hereinafter defined). Tenant
shall indemnify and hold Landlord harmless from any and all claims, costs,
damages, fines, judgments, penalties, losses, expenses or liabilities
(including, without limitation, any and all sums paid for settlement of claims,
attorneys' fees, consultant and expert fees) arising during or after the Term
from or in connection with the use, storage, handling, generation, transaction,

contractors or invitees only during the Term. Notwithstanding anything to the
contrary that may be contained in this Lease, Tenant's indemnification shall not
include any consequential damages (e.g., loss of rent, use and profits) incurred
by Landlord, but shall expressly include, without limitation, any and all costs
incurred due to any investigation of the site or any cleanup, removal or
restoration mandated by or pursuant to any Environmental Laws. Tenant's
indemnification shall survive any expiration or termination of the Term for
claims made up to one (1) year after the expiration or termination of the Term.

                  c. The parties hereby expressly acknowledge and agree that
nothing herein shall be construed as creating any liability, obligation,
covenant, representation or warranty upon Tenant whatsoever for any
environmental or other condition that may have existed on, at, under or in
the

                                      G-16

<PAGE>

vicinity of the Premises prior to the date of this Lease notwithstanding
Tenant's prior ownership or occupancy, except Tenant has retained responsibility
for certain corrective actions relating to a wastewater treatment pond located
on the Entire Premises all as set forth under the terms of the separate
agreement between Landlord and Tenant. Landlord does hereby expressly covenant
not to sue Tenant or any of Tenant's Parties with respect to any matter or thing
arising out of the environmental, health, safety or other condition on, at,
under or in the vicinity of the Premises which existed prior to Tenant's
occupancy under this Lease. Landlord hereby releases and discharges Tenant and
Tenant's Parties from any and all claims, costs, damages, fines, judgments,
penalties, losses, expenses or liabilities (including, without limitation, any
and all sums paid for settlement of claims, attorneys' fees, consultant and
expert fees) of any kind, whether known or unknown, which Landlord had, has or
at any time may have based any matter or thing arising out of the environmental,
health, safety or other condition on, at, under or in the vicinity of the
Premises which existed prior to Tenant's occupancy under this Lease.

                  d. As used herein, "Hazardous Substances" means any chemical,
compound, material, mixture, living organism or substance that is now or
hereafter defined or listed in, or otherwise classified pursuant to, any
"Environmental Laws" as a "hazardous substance", "hazardous material",
"hazardous waste", "extremely hazardous waste", "infectious waste", "toxic
substance", "toxic pollutant" or any other formulation intended to define, list,
or classify substances by reason of deleterious properties such as ignitability,
corrosivity, reactivity, carcinogenicity or toxicity, including any petroleum
polychlorinated biphenyls ("PCBs"), asbestos, radon, natural gas, natural gas
liquids, liquified natural gas or synthetic gas usable for fuel (or mixtures of
natural gas and such synthetic gas). The term "Environmental Laws" means any and
all present and future federal, state and local laws (whether under common law,
statute, rule, regulation or otherwise), requirements under permits issued with
respect thereto, and other requirements of "Governmental Authorities" (as
hereinafter defined) relating to the environment, or to any Hazardous Substance

Water Act, 42 U.S.C. ss.ss. 300f through 300j, as all of the foregoing may be
amended from time to time.

         22.      SIGNS

    Subject to Landlord's prior consent, which consent shall not be unreasonably
withheld or delayed, Tenant may install or construct any sign or signs on the
Entire Premises which Tenant deems desirable, provided that such sign complies
with all applicable laws and ordinances and with the Permitted Encumbrances.
Landlord approves all of Tenants' signs currently located on the Entire
Premises.

         23.      LIENS

                  a. Landlord shall keep the Premises free from any liens
arising out of any work performed, materials, furnished or obligations incurred
by or on behalf of Landlord and shall indemnify, defend and hold Tenant harmless
from all claims, costs and liabilities, including reasonable attorneys' fees and
costs, in connection with or arising out of any such lien or claim of lien.
Landlord shall cause any such lien imposed on the Premises to be released of
record by payment or posting of a proper bond within thirty (30) days after
written request by Tenant. Landlord also hereby waives any liens or lien rights
which it may have by statute or at common law with respect to any of Tenant's
trade fixtures, equipment or other property.

                  b. Tenant shall keep the Premises free from any liens arising
out of any work performed, materials furnished or obligations incurred by or on
behalf of and shall indemnify, defend and hold Landlord harmless from all
claims, costs and liabilities, including reasonable attorneys' fees and costs,

         24.      DEFAULT BY LANDLORD

    a. Landlord is in default under the terms of this Lease if Landlord fails in
the performance of any of its obligations under this Lease, and such failure
continues for a period of fifteen (15) days after Tenant shall have given
Landlord written notice specifying such failure in the event of a default which
may be cured solely by the payment of money and thirty (30) days after Tenant
shall have given Landlord written notice specifying any such failure which may
not be cured solely by the payment of money; provided that if such non-monetary
default complained of is of such a nature that the same cannot be completely
remedied or cured within such thirty (30) day period, then such default shall
not give Tenant the right to cure as hereinafter provided if Landlord shall have
commenced curing such default within such thirty (30) day period, and shall
proceed with reasonable diligence and in good faith to remedy the default
complained of.

         24A.     TENANT REMEDIES

                  a. Including Tenant's specific rights as set forth under
paragraph 6 hereof, Tenant has the right (but not the obligation) to cure such
nonperformance. If Landlord is in default under any of its obligations under
this Lease and such default materially interferes with Tenant's Intended Use,
Tenant shall be entitled to an abatement of Rent hereunder in proportion to the
extent of and during the period of any such interference.

                  b. If Tenant expends any sums in curing Landlord's default
pursuant to Subparagraph a. above, all reasonable sums incurred by Tenant
(together with interest accruing thereon at the Default Rate from and after the
date that Tenant expends any such sums) (collectively "Tenant's Expenditures")
shall be reimbursed by Landlord to Tenant within thirty (30) days following
Landlord's receipt of written demand therefor accompanied by supporting
invoices. If Landlord fails to repay Tenant's Expenditures when due, Tenant may
deduct an amount from each monthly installment of Base Rent that becomes due for
the remainder of the Term.

                  c. Notwithstanding anything to the contrary that may be
contained above, nothing herein shall be construed as preventing or restricting
Tenant from exercising any and all other rights and remedies available to Tenant
at law or in equity, even if such other rights and remedies conflict with or
contradict those set forth above, and further, all rights and remedies herein
described are cumulative and Tenant may exercise any one or all of them.

         25.      ATTORNEYS' FEES/SELF HELP

                  a. If either party brings any action or legal proceeding for
damages for an alleged breach of any provision of this Lease, to recover Rent or
other sums due, to terminate the tenancy of the Premises or to enforce, protect
or establish any term, condition or covenant of this Lease or right of either
party, the prevailing party shall be entitled to recover as a part of such
action or proceedings, or in a separate action brought for that purpose,
reasonable attorneys' fees and costs, at trial, on appeal and in bankruptcy, to
be fixed and determined by the court in such action or proceeding.

                  b. If either party ("Defaulting Party") is in default under
this Lease, the other party ("Nondefaulting Party") may, without being obligated
and without waiver of the default, cure the default. The Nondefaulting Party may
enter the Premises to cure the default. The Defaulting Party will pay the
Nondefaulting Party, upon demand, all reasonable costs, expenses and
disbursements incurred by the Nondefaulting Party to cure the default, together
with interest on all sums so expended at the Default Rate. The Nondefaulting
Party has the right to offset against any sums due from it hereunder any sums
advanced by the Nondefaulting Party to cure any defaults hereunder by the
Defaulting Party.

         26.      COMPLIANCE WITH LAWS

                                   G-18

<PAGE>

                  a. Landlord is currently, in compliance with, and will, at all
times during the Term, at its sole cost and expense, promptly comply with all
governmental laws, ordinances, rules or regulations applicable (including but
not limited to any modifications required to be made pursuant to the Americans
With Disabilities Act or otherwise) to the structure of the Building(s), the
parking lot, driveways, walkways and roadways, including without limitation all
Environmental Laws. Further, Landlord shall be responsible for any and all
expenditures for the required compliance arising from the nature of the use of
the Premises generally (meaning, if such compliance applies to office/warehouse
uses generally, as opposed to Tenant's particular business being conducted
thereon). However, notwithstanding any of the foregoing, Landlord shall not be
responsible for any compliance or costs relating to any Alterations made by
Tenant.

                  b. Tenant is in compliance with, and will, at all times during
the Term and at its sole cost and expense, promptly comply with all governmental
laws, ordinances, rules or regulations applicable (including but not limited to
any modifications required to be made), subject to any available
"grandfathering," to the particular manner in which Tenant conducts its business
on the Premises or which arise out of any Alterations made by Tenant; however,
in no event shall Tenant be required to make any Structural Alterations or
Alterations which are required to be made by Landlord, Landlord expressly
agreeing to make such Alterations.

         27.      RECORDING

                  At such time as Landlord delivers executed copies of this
Lease to Tenant, Landlord shall also deliver an executed short form
memorandum of this Lease substantially in the form attached as EXHIBIT I
modified only to the extent necessary to make it suitable for recording in
the jurisdiction where the Premises are located. Either Landlord or Tenant
may, if it so desires, record such memorandum at its own cost and expense. In
no event, however, shall this Lease be recorded.

         28.      LEASEHOLD MORTGAGES

                  Tenant may, without the prior written consent of Landlord,
subject the leasehold estate created by this Lease, as amended from time to
time, and its personal property, equipment and trade fixtures to a leasehold
mortgage and/or security agreement to secure financing or other obligations
which Tenant may obtain or incur. In connection with any such leasehold mortgage
and/or security agreement, Landlord will, promptly following receipt of written
request therefor, provide to Tenant's lender(s) an estoppel agreement confirming
whether or not this Lease has been amended, whether or not there are any uncured
defaults under this Lease, and such other matters pertaining to this Lease as
such lender(s) may reasonably require. In addition, Landlord will agree to
provide Tenant's lender(s) with written notice of any defaults by Tenant under
this Lease and the same opportunity to cure such defaults as herein provided to
Tenant before Landlord exercises its remedies under this Lease, and to provide
Tenant's lender(s) with a reasonable opportunity to enter upon the Premises for
the purpose of removing any property of Tenant which has been pledged as
collateral to Tenant's lender(s) or which has been subjected to any such
leasehold mortgage and/or security agreement.

         29.      LANDLORD REPRESENTATIONS AND WARRANTIES

                  a. Landlord hereby represents and warrants to Tenant that
it has good and marketable title to the Land, Building and Premises subject
only to the Permitted Encumbrances.

                  b. Landlord hereby represents and warrants to Tenant that the
Land is not located within an area designated by the Secretary of Housing and
Urban Development, the Army Corps of Engineers or any other governmental or
quasi-governmental agency as a "wetland" or special flood hazard area.

                  c. Parking. Landlord hereby represents and warrants to
Tenant that there are located upon the Entire Premises for the nonexclusive
and exclusive use by Tenant and exclusive, sufficient parking spaces and that
the Entire Premises complies with applicable zoning requirements for use of
all tenants of the

                                      G-19

<PAGE>

building(s) and their visitors and invitees and are not and will not be used in
connection with the occupancy of any other building, whether or not owned by
Landlord.

         30. NOVATION IN THE EVENT OF SALE

                  In the event of the sale of the Premises, Landlord shall be
and hereby is relieved of all of the covenants and obligations created hereby
accruing from and after the date of sale so long as the buyer assumes all
Landlord obligations in writing. Landlord, in the event of a sale of the
Premises, shall cause to be included in this agreement of sale and purchase a
covenant whereby the purchaser of the Premises assumes and agrees to carry out
all of the covenants and obligations of Landlord herein.

         31. SECURITY DEPOSIT

                  As additional security for Tenant's obligation to pay Rent
under this Lease, Tenant has as of the date hereof, deposited in an account at
Roundbank, Waseca, Minnesota, the amount of $203,817.00 (6 months Base Rent) as
a security deposit in connection with Tenant's obligation to pay Rent under this
Lease ("Security Deposit"). This Security Deposit account shall be in the name
of Landlord and shall be retained during the initial Term but not the Renewal
Term of this Lease. This Security Deposit will earn interest at the rate per
annum equal to 6 month Certificates of Deposit issued by Northeast Bank of
Minneapolis as such rate changes from time to time during the Term which
interest will not be included in the term "Security Deposit" and which interest
will be paid to Tenant quarterly by the Bank or Landlord. If Tenant defaults in
its obligation to pay Rent under this Lease such failure constitutes a default
under the provisions of Paragraph 15 of this Lease after any applicable notice
has been given and the notice period has run, Landlord can upon written notice
to Tenant apply so much of the Security Deposit as necessary against Tenant's
obligation to pay Rent. Landlord's application of the Security Deposit as
described herein, will not constitute Landlord's waiver of any of Landlord's
rights or remedies under this Lease or Landlord election of any specific remedy
to the exclusion of any other remedies available to Landlord under this Lease at
law or in equity. However in determining any damages for a Tenant default,
Tenant will receive a credit for so much of the Security Deposit as has been
applied by Landlord under this provision. If Landlord sells or otherwise conveys
the Entire Premises, for non-collateral security purposes, Landlord will
transfer the Security Deposit to the transferee for the benefit of Tenant.
Landlord is released from any obligation or liability to return the Security
Deposit to Tenant after such transfer if such transferee assumes all of
Landlord's obligations under the Lease and acknowledges receipt of the Security
Deposit from Landlord in writing with a notice to Tenant. In such event Tenant
will look solely to the transferee for the return of the Security Deposit. At
the end of the initial Term, Tenant will have the right to apply any unused
Security Deposit against monthly installments of Rent equal to the amount of the
unused Security Deposit. At the end of the Term or any earlier termination of
this Lease, any unused Security Deposit shall be returned to Tenant within 3
days of such event.

         32.      MISCELLANEOUS PROVISIONS

                  a. Time Periods. All periods of time referred to in this Lease
shall include all Saturdays, Sundays and state or national holidays, unless the
period of time specifies business days. However, if the date or last date to
perform any act or give notice or approval shall fall on a Saturday, Sunday or
state or national holiday, such act, notice or approval will be timely if
performed or given on the next succeeding day which is not a Saturday, Sunday or
state or national holiday.

                  b. The waiver by Landlord or Tenant of any breach of any term,
condition or covenant of this Lease will not be deemed to be a waiver of such
provision or any subsequent breach of the same or any other term, condition or
covenant of this Lease. No covenant, term or condition of this Lease will be
deemed to have been waived by Landlord or Tenant unless such waiver is in
writing and signed by the waiving party.

                  c. Severability. If any provision of this Lease is held to be
invalid, void or unenforceable, the remaining provisions hereof shall not be
affected or impaired, and such remaining provisions shall remain in full force
and effect.

incorporated by reference.

    e. Any fully executed copy of this Lease shall be deemed an original for all
purposes.

    f. The covenants and agreements contained in this Lease shall be binding on
the parties hereto and on their respective successors and permitted assigns.

    g. Captions. The captions and headings used in this Lease are for the
purpose of convenience only and shall not be construed to limit or extend the

between the parties, and there are no agreements or representations on the
leasing of the Premises between the parties except as expressed herein.

    i. This Lease is intended to express the mutual intent of the parties
hereto, and no rule of strict construction shall be applied against either
Landlord or Tenant.

    j. Time is of the essence in every particular of this Lease in respect to
the promises, covenants and agreements, terms and conditions of either Landlord
or Tenant. The foregoing will not operate, however, to reduce the time period
allocated for the performance of any obligation or the curing of any default if
a time period is specified in the Lease for the performance of such obligation
or the curing of such default.

                  k. All references herein to the Landlord and Tenant mean the
persons who from time to time occupy the positions, respectively, of the
Landlord and Tenant, although this will not be construed as relieving any
person, firm or corporation of any liability incurred by him, her or it, by
reason of or in connection with his, her or its having been Landlord or Tenant
at one time or another.

                  l. This Lease shall be governed in all respects by the laws of
the State of Minnesota.

    m. Each party hereby represents and warrants to the other that the person or
entity signing this Lease on behalf of such party is duly authorized to execute
and deliver this Lease and to legally bind the party on whose behalf this Lease
is signed to all of the terms, covenants and conditions contained in this Lease.

                  n. Notwithstanding anything to the contrary in the Lease,
Landlord shall have the duty to mitigate damages in the event of default, INTER
ALIA, by using reasonable efforts to re-let the Premises.

                  o. Landlord hereby disclaims, waives and acknowledges that it
has no right to any statutory or other lien upon any and all property owned by
Tenant to the fullest extent permissible by law.

         33.      NO OFFER

    The submission of this Lease for examination or the negotiation of the
transaction described herein or the execution of this Lease by only one of the
parties will not in any way constitute an offer to lease on behalf of either
Landlord or Tenant, and this Lease shall not be binding on either party until
duplicate originals thereof, duly executed on behalf of both parties, have been
delivered to each of the parties hereto.

         34.      FORCE MAJEURE

                  Neither Landlord nor Tenant will be deemed in default with
respect to any provision, covenant or condition of this Lease on the part of
either of them, respectively, to be performed if the performance thereof will be
delayed, interfered with or rendered impossible because of any strike, lock-out,
civil commotion, war, war-like operation, invasion, insurrection, rebellion,
hostility, revolution, military or usurped power, sabotage, inability to obtain
any necessary material or service, unusual, severe and adverse

                                      G-21

<PAGE>

weather conditions or other cause beyond the control of the party obligated to
execute such performance; further, however, that such performance shall be
resumed with due diligence and reasonable dispatch as soon as the contingency
causing such delay or impossibility shall abate; and provided further, however,
that nothing in this paragraph contained shall operate or be construed to
relieve either party of any obligation for the payment of money promptly as the
same shall be due.

         35.      ARBITRATION

                  If any dispute shall arise between Landlord and Tenant with
reference to the interpretation of this Lease, their respective rights and
obligations hereunder or with respect to any future determination to be made
pursuant to the Lease (such as Tenant's Share of Operating Costs and the amount
of Additional Rent), such dispute, upon the written request of either party,
shall be submitted to an arbitrator chosen by the parties. If the parties are
unable to agree upon an arbitrator, each party shall select an arbitrator and
these two arbitrators shall select the Chief Arbitrator. If the two arbitrators
fail to agree in the selection of a Chief Arbitrator within thirty (30) days of
their appointment, each of them shall name two prospective arbitrators, of whom
the other shall decline one and the final selection of a Chief Arbitrator shall
be made among the two remaining names by drawing that arbitrators name out of a
hat in the presence of the Landlord and Tenant. The parties may agree upon any
individual as an arbitrator but if they are unable to agree, ALL arbitrators
must have a relationship with an institutional arbitration entity such as the
American Arbitration Association, Endispute, or Judicate. The arbitrator shall
interpret this Lease as an honorable engagement and not merely a legal
obligation; they are relieved of all judicial formalities and may abstain from
following the strict rules of law, and they shall make their award with a view
to effecting the general purpose of the Lease in a reasonable manner rather than
in accordance with a literal interpretation of the language. Insofar as
appropriate, the arbitrators shall take into account the parties prior
understanding including, for example, the manner in which the Tenant's Share of
Operating Expenses has been determined. Each party shall submit its case to its
arbitrator within thirty (30) days of the appointment of the arbitrator.

                  The decision in writing of the arbitrators, when filed with
the parties hereto, shall be final and binding on both parties. If the
arbitrators are unable to reach a unanimous decision, the Chief Arbitrator shall
issue the decision which need not be consistent with either of the other two
arbitrators. The deliberations of the arbitrators shall be confidential and no
dissenting opinion shall be rendered in writing or orally. Judgment may be
entered upon the final decision of the arbitrators in any court having
jurisdiction. The expenses of arbitration shall be borne equally by Landlord and
Tenant except that each shall bear their own expenses and if more than one
arbitrator is required, each party shall bear the expense of its own arbitrator
and shall jointly and equally bear with the other party the expense of the Chief
Arbitrator and of the arbitration. Said arbitration shall take place in
Minneapolis, Minnesota, unless some other place is mutually agreed upon by the
parties.

                  IN WITNESS WHEREOF, the parties hereto have duly executed this
Lease as of the day and year first above written.
