     The payment of the sums set forth in this Article 3 shall be in addition to
the Base Rent payable pursuant to Article 2 of this Lease. All sums due
hereunder shall be due and payable within thirty (30) days of delivery of
written certification by Lessor setting forth the computation of the amount due
from Lessee. In the event the lease term shall begin or expire at any time
during the calendar year, Lessee shall be responsible for his pro-rata share of
Additional Rent under subdivisions a. and b. during the Lease and/or occupancy
time.

     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, Lessor will estimate for each calendar year (i) the total
amount of Real Estate Taxes; (ii) the total amount of Operating Expenses; (iii)
Lessee's share of Real Estate Taxes for such calendar year; (iv) Lessee's share
of Operating Expenses for such calendar year; and (v) the computation of the
annual and monthly rental payable during such calendar year as a result of
increases or decreases in Lessee's share of Real Estate Taxes, and Operating
Expenses.
Said estimates will be in writing and will be delivered or mailed to Lessee.

     The amount of Lessee's share of Real Estate Taxes, and 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 at the option of Lessor. In the event that such estimate is
delivered to Lessee 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 Lessee 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 calendar months remaining in such
calendar year.

     Upon completion of each calendar year during the term of this Lease or any
renewal or extensions thereof, Lessor shall cause its accountants to determine
the actual amount of the Real Estate Taxes, and Operating Expenses payable in
such calendar year and Lessee's share thereof and deliver a written
certification of the amounts thereof to Lessee. If Lessee has underpaid its
share of Real Estate Taxes, or Operating Expenses for such calendar year, Lessee
shall pay the balance of its share of same within ten (10) days after the
receipt of such statement. If Lessee has overpaid its share of Real Estate
Taxes, or Operating Expenses for such calendar year, Lessor shall either (i)
promptly refund such excess, or (ii) credit such excess against the most current
monthly installment or installments due Lessor for its estimate of Lessee's
share of Real Estate Taxes, and Operating Expenses for the next following
calendar year. A prorata adjustment shall be made for a fractional calendar year
occurring during the term of the Lease 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 Lessee or credits due Lessee as a result of the provision of this Article 3
shall be adjusted accordingly.

COVENANT TO PAY RENT:

     4. The covenants of Lessee to pay the Base Rent and the Additional Rent are

charges for garbage disposal, refuse removal, water, electricity, gas, telephone
and/or other utility services or energy source furnished to the Demised Premises
during the term of this Lease, or any renewal or extension thereof. If Lessor
elects to furnish any of the foregoing utility services of other services
furnished or caused to be furnished to Lessee, then the rate charged by Lessor
shall not exceed the rate Lessee would be required to pay to a utility company
or service company furnishing any of the foregoing utilities or services. The
charges thereof shall be deemed additional rent in accordance with Article 3. It
is understood that gas and electrical service for the Demised Premises is

as may be necessary to compensate or repay Lessor for all losses or damages
sustained or to be sustained by Lessor due to such breach on the part of Lessee,
including, but not limited to overdue and unpaid rent, any other sum payable by
Lessee to Lessor pursuant to the provisions of this Lease, damages or
deficiencies in the reletting of Demised Premises, and reasonable attorney's
fees incurred by Lessor. Should the entire deposit or any portion thereof, be
appropriated and applied by Lessor, in accordance with the provisions of this
paragraph, Lessee upon written demand by Lessor, shall remit forthwith to Lessor
a sufficient amount of cash to restore said security deposit to the original sum
deposited, and Lessee's failure to do so within five (5) ten (10) days after
receipt of such demand shall constitute a breach of this Lease. Said security
deposit shall be returned to Lessee, less any depletion thereof as the result of
the provisions of this paragraph, at the end of the term of this Lease or any
renewal thereof, or upon the earlier termination of this Lease. Lessee shall
have no right to anticipate return of said deposit by withholding any amount
required to be paid pursuant to the provision of this Lease or otherwise.

     In the event Lessor shall sell the Premises, or shall otherwise convey or
dispose of its interest in this Lease, Lessor will assign aid security deposit
or any balance thereof to Lessor's assignee, whereupon Lessor shall be released
from all liability for the return or repayment of such security deposit and
Lessee shall look solely to the said assignee for the return and repayment of
said security deposit. Said security deposit shall not be assigned or encumbered
by Lessee without such consent of Lessor, and any assignment or encumbrance
without such consent shall not bind Lessor. In the event of any rightful and
permitted assignment of this Lease by Lessee, said security deposit shall be
deemed to be held by Lessor as a deposit made by the assignee, and Lessor shall
have no further liability with respect to the return of said security deposit to
Lessee.

requirement of law or of any public authority, Lessor shall be obligated on
account of the purpose or manner of said use to make any addition or alteration

any laws, ordinances, rules, regulations or requirements of any public authority
or of the Board of Fire Underwriters or any similar body or that Lessor may deem
necessary to prevent waste or deterioration in connection with the Demised
Premises. Nothing herein shall imply any duty upon the part of Lessor to do any
such work which, under any provision of this Lease, Lessee may be required to
perform and the performance thereof by Lessor shall not constitute a waiver of

progress of any work in the Demised Premises, keep and store upon the Demised
Premises all necessary materials, tools and equipment. The Lessor shall not in
any event be liable for inconvenience, annoyance, disturbance, loss of business,

private sale in lieu thereof in respect to the Premises during the term thereof,

domain or any public or quasi-public use or purpose, then the term of this Lease
shall cease and terminate as of the date possession shall be taken in such
proceeding and all rentals shall be paid up to that date.

     b. If any part constituting less than the whole of the Premises shall be
acquired or condemned as aforesaid, and in the event that such partial taking or
condemnation shall materially affect the Demised Premises so as to render the
Demised Premises unsuitable for the business of Lessee, in the reasonable
opinion of Lessor and Lessee, then the term of this Lease shall cease and
terminate as of the date possession shall be taken by the condemning authority
and rent shall be paid to the date of such termination.

     In the event of a partial taking or condemnation of the Premises which
shall not materially affect the Demised premises so as to render the Demised
Premise unsuitable for the business of Lessee, in the reasonable opinion of
Lessor, this Lease shall continue in full force and effect but with a
proportionate abatement of the Base Rent and Additional Rent based on the
portion, if any, of the Demised Premise taken. Lessor reserves the right, at its
option, to restore the Building and the Demised Premises to substantially the
same condition as they were prior to such condemnation. In such event, Lessor

restore. Upon Lessor's notice of election to restore, Lessor shall commence
restoration and shall restore the Building and the Demised Premises with
reasonable promptness, subject to delays beyond Lessor's control and delays in

shall have no right to terminate this Lease except as herein provided. Upon
completion of such restoration, the rent shall be adjusted based upon the
portion, if any, of the Demised Premises restored.

     c. In the event of any condemnation or taking as aforesaid, whether whole
or partial, Lessee shall not be entitled to any part of the award paid for such
condemnation and Lessor is to receive the full amount of such award, Lessee
hereby expressly waiving any right to claim to any part thereof.

     d. Although all damages in the event of any condemnation shall belong to
Lessor whether such damages are awarded as compensation for diminution in value
of the leasehold or to the fee of the Demised Premises, Lessee shall have the
right to claim and recover from the condemnating authority, but not from Lessor,
such compensation as may be separately awarded or recoverable by Lessee in
Lessee's own right on account of any and all damage to Lessee's business by
reason of the condemnation and for or on account of any cost or loss to which
Lessee might be put in removing Lessee's merchandise, furniture, fixtures,
leasehold improvements and equipment. However, Lessee shall have no claim
against Lessor or make any claim with the condemning authority of the loss of
its leasehold estate, any unexpired term of loss of any possible renewal or
extension of said lease or loss of any possible value of said lease, any
unexpired term, renewal or extension of said Lease.

other cause during the term hereof, the following provisions shall apply:

that the cost of restoration, as reasonably estimated by Lessor, will equal or
exceed thirty percent (30%) of the replacement value of the Building (exclusive

later than the sixtieth (60th) day following the damage, give Lessee written
notice of Lessor's election to terminate this Lease.

     b. If the cost of restoration as estimated by Lessor will equal or exceed
fifty percent (50%) of said replacement value of the Building and if the Demised
Premises are not suitable as a result of said damage for the purposes for which
they are demised hereunder, in the reasonable opinion of Lessee, then Lessee
may, no later than the sixtieth (60th) day following the damage, give Lessor a
written notice of election to terminate this Lease.

     c. If the cost of restoration as estimated by Lessor shall amount to less
than thirty percent (30%) of said replacement value of the Building, or if,
despite the cost, Lessor does not elect to terminate this Lease, Lessor shall
restore the Building and the Demised Premises with reasonable promptness,
subject to delays beyond Lessor's control and delays in the making of insurance
adjustments by Lessor; and Lessee shall have no right to terminate this Lease
except as herein provided. Lessor shall not be responsible for restoring or
repairing leasehold improvements of Lessee.

     d. In the event of either of the elections to terminate, this Lease shall
be deemed to terminate on the date of the receipt of the notice of election and
all rentals shall be paid up to that date. Lessee shall have no claim against
Lessor for the value of any unexpired term of this Lease.

     e. In any case where damage to the Building shall materially affect the
Demised Premises so as to render them unsuitable in whole or in part for the
purposes for which they are demised hereunder, then, unless such destruction was
wholly or partially caused by the negligence or breach of the terms of this
Lease by Lessee, its employees, contractors or licensees, a portion of the rent
based upon the amount of the extent to which the Demised Premises are rendered
unsuitable shall be abated until repaired or restored. If the destruction or
damage was wholly or partially caused by negligence or breach of the terms of
this Lease by Lessee as aforesaid and if Lessor shall elect to rebuild, the rent
shall not abate and Lessee shall remain liable for the same.

CASUALTY INSURANCE:

     15. a. Lessor shall at all times during the term of this Lease, at its
expense, maintain a policy or policies of insurance with premiums paid in
advance issued by an insurance company licensed to do business in the State of
Minnesota insuring the Building against loss or damage by fire, explosion or
other insurable hazards and contingencies for the full replacement value,
provided that Lessor shall not be obligated to insure any furniture, equipment,
machinery, goods or supplies not covered by this Lease which Lessee may bring
upon the Demised Premises or any additional improvements which Lessee may
construct or install on the Demised Premise.

     b. Lessee shall not carry any stock of goods or do anything in or about the
Demised Premises which will in any way impair or invalidate the obligation of
the insurer under any policy of insurance required by this Lease.

     c. Lessor hereby waives and releases all claims, liabilities and causes of
action against Lessee and its agents, servants and employees for loss or damage
to, or destruction of, the Premises or any portion thereof, including the
buildings and other improvements situated thereon, resulting from fire,
explosion and other perils included in standard extended coverage insurance,
whether caused by the negligence of any of said persons or otherwise. Likewise,
Lessee hereby waives and releases all claims, liabilities and causes of action
against Lessor and its agents, servants and employees for loss or damage to, or
destruction of, any of the improvements, fixtures, equipment, supplies,
merchandise and other property, whether that of Lessee or of others, upon or
about the Premises resulting from fire, explosion or the other perils included
in standard extended coverage insurance, whether caused by the negligence of any
of said persons or otherwise. The waiver shall remain in force whether or not
Lessee's insurer shall consent thereto.

     d. In the event that the use of the Demised Premises by Lessee increases
the premium rate for insurance carried by Lessor on the improvements of which
the Demised Premises are a part, Lessee shall pay Lessor, upon demand, the
amount of such premium increase. If Lessee installs any electrical equipment
that overloads the power lines to the building or its wiring, Lessee shall, at
its own expense, make whatever changes are necessary to comply with the
requirements of the insurance underwriter, insurance rating bureau and
governmental authorities having jurisdiction.

PUBLIC LIABILITY INSURANCE:

     16. Lessee shall during the term hereof keep in full force and effect at
its expense a policy or policies of public liability insurance with respect to
the Demised Premises and the business of Lessee, in which both Lessee and Lessor
shall be covered by being named as insured parties under reasonable limits of
liability not less than: $500,000 for injury/death to any one person; $1,000,000
for injury/death to more than one person, and $500,000 with respect to damage to
property. Such policy or policies shall provide that ten (10) days written
notice must be given to Lessor prior to cancellation thereof. Lessee shall
furnish evidence satisfactory to Lessor at the time this Lease is executed that
such coverage is in full force and effect.

DEFAULT OF LESSEE:

     17. a. In the event of any failure of Lessee to pay any rental due
hereunder within ten (10) days written notice or any failure to perform any
other of the terms, conditions or covenants of this Lease to be observed or
performed by Lessee for more than thirty (30) days after written notice of such
failure shall have been given to Lessee, or if Lessee or an agent of Lessee
shall falsify any report required to be furnished to Lessor pursuant to the
terms of this Lease, or if Lessee or any guarantor of this Lease shall become
bankrupt or insolvent, or file any debtor proceedings or any person shall take
or have against Lessee or any guarantor of this Lease in any court pursuant to
any statue either of the United States or of any state a petition of bankruptcy
or insolvency or for reorganization or for the appointment of a receiver or
trustee of all or a portion of Lessee's or any such guarantor's property, or if
Lessee or any such guarantor makes an assignment for the benefit or creditors,
or petitions for or enters into an arrangement, or if Lessee shall abandon the
Demised Premises or suffer this Lease to be taken under any writ of execution,
then in any such event Lessee shall be in default hereunder, and Lessor, in
addition to other rights of remedies it may have, shall have the immediate right
or re-entry and may remove all persons and property from the Demised Premises
and such property may be removed and stored in a public warehouse or elsewhere
at the cost of, and for the account of Lessee, all without service of notice or
resort to legal process and without being guilty of trespass, or becoming liable
for any loss or damage which may be occasioned thereby.


                                       8

     b. Should Lessor elect to re-enter the Demised Premises, as herein
provided, or should it take possession of the Demised Premises pursuant to legal
proceedings or pursuant to any notice provided for by law, it may either
terminate this Lease or it may from time to time, without terminating this
Lease, make such alterations and repairs as may be necessary in order to relet
the Demised Premises, and relet the Demised Premises or any part thereof upon
such term or terms (which may be for a term extending beyond the term of this
Lease) and at such rental or rentals and upon such other terms and conditions as
Lessor in its sole discretion may deem advisable. Upon each such subletting all
rentals received by Lessor from such reletting shall be applied first to the
payment of any indebtedness other than rent due hereunder from Lessee to Lessor;
second, to the payment of any costs and expenses of such reletting, including
brokerage fees and attorney's fees and costs of such alterations and repairs;
third, to the payment of the rent due and unpaid payment of future rent as the
same may become due and payable hereunder. If such rentals received from such
reletting during any month be less than that to be paid during that month by
Lessee hereunder, Lessee, upon demand, shall pay any such deficiency to Lessor.
No such re-entry or taking possession of the Demised Premises by Lessor shall be
construed as an election on its part to terminate this Lease unless a written
notice of such intention be given to Lessee or unless the termination thereof be
decreed by a court of competent jurisdiction. Notwithstanding any such reletting
without termination, Lessor may at any time after such re-entry and reletting
elect to terminate this Lease for any such breach, in addition to any other
remedies it may have, it may recover from Lessee all damages it may incur by
reason of such breach, including the cost of recovering the Demised Premises,
reasonable attorney's fees, and including the worth at the time of such
termination of the excess, if any, of the amount of rent and charges equivalent
to rent reserved in this Lease for the remainder of the stated term over the
then reasonable rental value of the Demised Premises for the remainder of the
slated term, all of which amounts shall be immediately due and payable from
Lessee to Lessor.

     c. Lessor may, at its option, instead of exercising any other rights or
remedies available to it in this Lease or otherwise by law, statue or equity,
spend such money as is reasonably necessary to cure any default of Lessee herein
and the amount so spent, and costs incurred, including attorney's fees in curing
such default, shall be paid by Lessee, and additional rent, upon demand.

     d. In the event suit shall be brought for recovery of possession of the
Demised Premises, for the recovery of rent of any other amount due under the
provisions of this Lease, or because of the breach of any other covenant herein
contained on the part of Lessee to be kept or performed, and a breach shall be
established, Lessee shall pay to Lessor all expenses incurred therefor,
including a reasonable attorney's fee, together with interest on all such
expenses at the rate of ten percent (10%) per annum from the date of such breach
of the covenants of this Lease.

     e.  Intentionally deleted

     f. No remedy herein or elsewhere in this Lease or otherwise by law, statue
or equity, conferred upon or reserved to Lessor or Lessee shall be exclusive of
any other remedy, but shall be cumulative, and may be exercised from time to
time and as often as the occasion may arise.



COVENANTS TO HOLD HARMLESS:

     18. Unless the liability for damage or loss is caused by the gross
negligence of Lessor, its agents or employees, Lessee shall hold harmless Lessor
from any liability for damages to any person or property in or upon the Demised
Premises and the Premises, including the person and the property of Lessee and
its employees and all persons in the Building at its or their invitation or
sufferance, and from all damages resulting from Lessee's failure to perform the
covenants of this Lease. All property kept, maintained or stored on the Demised
Premises shall be so kept, maintained or stored at the sole risk of Lessee.
Lessee agrees to pay all sums of money in respect of any labor, service,
materials, supplies or equipment furnished or alleged to have been furnished to
Lessee in or about the Premises, and not furnished on order of Lessor, which may
be secured by and Mechanic's Materialmen's or other lien to be discharged at the
time performance of any obligation secured thereby matures, provided that Lessee
may contest such lien, but if such lien is reduced to final judgment and if such
judgment or process thereon is not stayed, or if stayed and said stay expires,
then and in each such event, Lessee shall forthwith pay and discharge said
judgment. Lessor shall have the right to post and maintain on the Demised
Premises, notices of non-responsibility under the laws of the State of
Minnesota.

NON-LIABILITY:

     19. Subject the terms and conditions of Article 14 hereof, Lessor shall not
be liable for damage to any property of Lessee or of others located on the
Premises, not for the loss of or damage to any property of Lessee or of others
by theft or otherwise. Lessor shall not be liable for any injury or damage to
persons or property resulting from fire, explosion, falling plaster, steam, gas,
electricity, water, rain or snow or leaks from any part of the Premises or from
the pipes, appliances, or plumbing works or from the roof, street or subsurface
or from any other place or by dampness or by any other cause of whatsoever
nature. Lessor shall not be liable for any such damage caused by other Lessees
or persons in the Premises, occupants of adjacent property, of the buildings, or
the public or caused 


                                       9
<PAGE>   9
by operations in construction of any private, public or
quasi-public work. All property of Lessee kept or stored on the Demised Premises
shall be so kept or stored at the risk of Lessee only and Lessee shall hold
Lessor harmless from any claims arising out of damage to the same, including
subrogation claims by Lessee's insurance carrier.

SUBORDINATION:

     20. This Lease shall be subordinated to any mortgages that may now exist or
that may hereafter be placed upon the Demised Premises and to any and all
advances made thereunder, and to the interest upon the indebtedness evidenced by
such mortgages, and to all renewals, replacements and extensions thereof. In the
event of execution by Lessor after the date of this Lease of any such mortgage
renewal, replacement or extension, Lessee agrees to execute a subordination
agreement with the holder thereof which agreement shall provide that:

     a. Such holder shall not disturb the possession and other rights of Lessee
under this Lease so long as Lessee is not in default hereunder,

     b. In the event of acquisition of title to the Demised Premises by such
holder, such holder shall accept Lessee as Lessee of the Demised Premises under
the terms and conditions of this Lease and shall perform all the obligations of
Lessor hereunder, and

     c. Lessee shall recognize such holder as Lessor hereunder.

     Lessee shall, upon receipt of a request from Lessor therefore, within ten
(10) days after receipt of such request, execute and deliver to Lessor or to any
proposed holder of a mortgage or trust deed or to any proposed purchaser of the
Premises, a certificate in recordable form, certifying that this Lease is in
full force and effect, and that there are no offsets against rent nor defenses
to Lessee's performance under this Lease, or setting further any such offsets or
defenses claimed by Lessee, as the case may be.

ASSIGNMENT OR SUBLETTING:

     21. Lessee agrees to use and occupy the Demised Premises throughout the
entire term hereof for the purpose or purposes herein specified and for no other
purposes, in the manner and to substantially the extent now intended, and not to
transfer or assign this Lease or sublet said Demised Premises, or any part
thereof, whether by voluntary act, operation of law, or otherwise, without
obtaining the prior written consent of Lessor in each instance. Lessee shall
seek such consent of Lessor by a written request therefor, setting forth such
information as Lessor may deem necessary. Lessor agrees not to withhold consent
unreasonably. Consent by Lessor to any assignment of this Lease or to any
subletting of the Demised Premises shall not be a waiver of Lessor's rights
under this Article as to any subsequent assignment or subletting. Lessor's
rights to assign this Lease are and shall remain unqualified. No such assignment
or subleasing shall relieve Lessee from any of Lessee's obligations in this
Lease contained, nor shall any

assignment or sublease or other transfer of this Lease be effective unless the
assignees, sublessee or transferee shall at the time of such assignment,
sublease or transfer, assume in writing for the benefit of Lessor, its
successors or assigns, all of the terms, covenants and conditions of this Lease
thereafter to be performed by Lessee and shall agree in writing to be bound
thereby. Should Lessee sublease in accordance with the terms of this Lease,
fifty percent (50%) of any increase in rental received by Lessee over the per
square foot rental rate which is being paid by Lessee shall be forwarded to and
retained by Lessor, less any costs incurred by Lessee for such assignment of
sublet, which increase shall be in addition to the Base Rent and Additional Rent
due Lessor under this Lease.

ATTORNMENT:

     22. In the event of a sale or assignment of Lessor's interest, in the
Premises, or the Building in which the Demised Premises are located, or this
Lease, or if the Premises come into custody or possession of a mortgagee or any
other party whether because of a mortgage foreclosure, or otherwise, Lessee
shall attorn to such assignee or other party and recognize such party as Lessor
hereunder; provided, however Lessee's peaceable possession will not be disturbed
so long as Lessee faithfully performs its obligations under this Lease. Lessee
shall execute, on demand, any attornment agreement required by any such party to
be executed, containing such provisions and such other provisions as such party
may require.

NOVATION IN THE EVENT OF SALE:

     23. In the event of the sale of the Demised Premises, Lessor shall be and
hereby is relieved of all of the covenants and obligations created hereby
accruing from and after the date of sale, and such sale shall result
automatically in the purchaser assuming and agreeing to carry out all the
covenants and obligations of Lessor herein. Notwithstanding the foregoing
provisions of this Article, Lessor, in the event of a sale of the Demised
Premises, shall cause to be included in this agreement of sale and purchase a
covenant whereby the purchaser of the Demised Premises assumes and agree to
carry out all of the covenants and obligations of Lessor herein.

     The Lessee agrees at any time and from time to time upon not less than ten
(10) days prior written request by Lessor to execute, acknowledge and deliver to
Lessor a statement in writing certifying that this Lease is unmodified and in
full force and effect as modified and stating the 


                                       10

<PAGE>   10
modifications, and the dates to which the basic rent and other charges have
been paid in advance, if any, it being intended that any such statement
delivered pursuant to this paragraph may be relied upon by any prospective
purchaser of the fee or mortgagee or assignee of any mortgage upon the fee of
the Demised Premises. 
SUCCESSORS AND ASSIGNS:

     24. The terms, covenants and conditions hereof shall be binding upon and
inure to the successors and assigns of the parties hereto.

REMOVAL OF FIXTURES:

     25. Notwithstanding anything contained in Article 8, 29 or elsewhere in
this Lease, with the exception of the initial improvements as noted herein and
attached as Exhibit D, if Lessor requests then Lessee will promptly remove at
the sole cost and expense of Lessee all fixtures, and equipment installed by
Lessee simultaneously with vacating the Demised Premises and Lessee will
promptly restore said Demised Premises to the condition that existed immediately
prior to said fixtures and equipment having been installed, all at the sole cost
and expense of Lessee.

QUIET ENJOYMENT:

     26. Lessor warrants that it has full right to execute and to perform this
Lease and to grant the estate demised, and that Lessee, upon payment of the
rents and other amounts due and the performance of all the terms, conditions,
covenants and agreements on Lessee's part to be observed and performed under
this Lease, may peaceably and quietly enjoy the Demised Premises for the
business uses permitted hereunder, subject, nevertheless, to the terms and
conditions of this Lease.

RECORDING:

     27. Lessee shall not record this Lease without the written consent of
Lessor. However, upon the request of either party hereto, the other party shall
join in the execution of the Memorandum lease for the purposes of recordation.
Said Memorandum lease shall describe the parties, the Demised Premises and the
term of the Lease and shall incorporate this Lease by reference. This Article 27
shall not be construed to limit Lessor's right to file this Lease under Article
22 of this Lease.

OVERDUE PAYMENTS:

     28. All monies due under this Lease from Lessee to Lessor shall be due on
demand, unless otherwise specified and if not paid within five (5) days of when
due, shall result in the imposition of a service charge for such late payment in
the amount of five percent (5%) of the amount due.




SURRENDER:

     29. On the Expiration Date or upon the termination hereof upon a day other
than the Expiration Date, Lessee shall peaceably surrender the Demised Premises
broom-clean in good order, condition and repair, reasonable wear and tear only
excepted. On or before the Expiration Date or upon termination of this Lease on
a day other than the Expiration Date, Lessee shall, at its expense, remove all
trade fixtures, personal property and equipment and signs from the Demised
Premises and any property not removed shall be deemed to have been abandoned.
Any damage caused in the removal of such items shall be repaired by Lessee and
at its expense. All alterations, additions, improvements and fixtures (other
than trade fixtures) which shall have been made or installed by Lessor or Lessee
upon the Demised Premises and all floor covering so installed shall at the
option of Lessor remain upon and be surrendered with the Demised Premises as a
part thereof, without disturbance, molestation or injury, and without charge, at
the expiration or termination of this Lease. If the Demised Premises are not
surrendered on the Expiration Date or the date of termination, Lessee shall
indemnify Lessor against loss or liability, claims, without limitation, made by
any succeeding Lessee founded on such delay. Lessee shall promptly surrender all
keys for the Demised Premises to Lessor at the place then fixed for payment of
rent and shall inform Lessor of combinations of any locks and safes on the
Demised Premises.

HOLDING OVER:

     30. In the event of a holding over by Lessee after expiration or
termination of this Lease without the consent in writing of Lessor, Lessee shall
be deemed a lessee at sufferance and shall pay rent for such occupancy at the
rate of 150% the lease-current aggregate Base and Additional Rent, prorated for
the entire holdover period, plus all attorney's fees and expenses incurred by
Lessor in enforcing its rights hereunder, plus any other damages occasioned by
such holding over. Except as otherwise agreed, any holding over with the written
consent of Lessor shall constitute Lessee a month-to-month lessee.

ABANDONMENT:

     31. Intentionally deleted

CONSENTS BY LESSOR:

     32. Whenever provision is made under this Lease for Lessee securing the
consent or approval by Lessor, such consent or approval shall only be in
writing, and shall not be unreasonably withheld or delayed.


                                       11
<PAGE>   11

NOTICES:

     33. Any notice required or permitted under this Lease shall be deemed
sufficiently given or secured if sent by registered or certified return receipt
mail to Lessee at Lake Corporate Center, 8091 Wallace Road, Eden Prairie,
Minnesota and to Lessor at the address then fixed for the payment of rent as
provided in Article 4 of this Lease, and either party may by like written notice
at any time designate a different address to which notices shall subsequently be
sent or rent to be paid.

RULES AND REGULATIONS:

     34. Lessee shall observe and comply with the rules and regulations as
Lessor may prescribe, on written notice to Lessee for the safety, care and
cleanliness of the Building.

INTENT OF PARTIES:

     35. Except as otherwise provided herein, Lessee covenants and agrees that
if it shall any time fail to pay any such cost or expenses, or fail to take out,
pay for, maintain or deliver any of the insurance policies above required, or
fail to make any other payment or perform any other act on its part to be made
or performed as in this Lease provided, then Lessor may, but shall not be
obligated so to do, and without notice to or demand upon Lessee and without
waiving or releasing Lessee from any obligations of Lessee in this Lease
contained, pay any such cost or expense, effect any such insurance coverage and
pay premiums therefor, and may make any other payment or perform any other act
on the part of Lessee to be made and performed as in this Lease provided, in
such manner and to such extent as Lessor may deem desirable, and in exercising
any such right, to also pay all necessary and incidental costs and expenses,
employ counsel and incur and pay reasonable attorneys' fees. All sums so paid by
Lessor and all necessary and incidental costs and expenses in connection with
the performance of any such act by Lessor, together with interest thereon at the
rate of ten percent (10%) per annum from the date of making of such expenditure,
by Lessor, shall be deemed additional rent hereunder, and shall be payable to
Lessor on demand. Lessee covenants to pay any such sum or sums with interest as
aforesaid and Lessor shall have the same rights and remedies in the event of the
non-payment thereof by Lessee as in the case of default by Lessee in the payment
of the Base Rent payable under this Lease.

GENERAL:

     36. The Lease does not create the relationship of principal and agent or of
partnership or of joint venture or of any association between Lessor and Lessee,
the sole relationship between the parties hereto being that of Lessor ad Lessee.

     No waiver of any default of Lessee hereunder shall be implied from any
omission by Lessor to take any action on account of such default if such default
persists or is repeated,

and no express waiver shall affect any default other than the default specified
in the express waiver and that only for the time and to the extent therein
stated. One or more waivers by Lessor shall not then be construed as a waiver of
a subsequent breach of the same covenant, term or condition. The consent to or
approval by Lessor of any act by Lessee requiring Lessor's consent or approval
shall not waive or render necessary Lessor's consent to or approval of any
subsequent similar act by Lessee shall be construed to be both a covenant and a
condition. No action required or permitted to be taken by or on behalf of Lessor
under the terms or provisions of this Lease shall be deemed to constitute an
eviction or disturbance of Lessee's possession of the Demised Premises. All
preliminary negotiations are merged into and incorporated in this Lease. The
laws of the State of Minnesota shall govern the validity, performance and
enforcement of this Lease.

     a. This Lease and the exhibits, if any, attached hereto and forming a part
hereof, constitute the entire agreement between Lessor and Lessee affecting the
Demised Premises and there are no other agreements, either oral or written,
between them other than are herein set forth. No subsequent alteration,
amendment, change or addition to this Lease shall be binding upon Lessor or
Lessee unless reduced to writing and executed in the same form and manner in
which this Lease is executed.

     b. If any agreement, covenant or condition of this Lease or the application
thereof to any person or circumstances shall, to any extent, be invalid or
unenforceable, the remainder of this Lease, or the application of such
agreement, covenant or condition to persons or circumstances other than those as
to which it is held invalid or unenforceable, shall not be affected thereby and
each agreement, covenant or condition of this Lease shall be valid and be
enforced to the fullest extent permitted by law.

HAZARDOUS MATERIAL:

     37. a. The Demised Premises hereby leased shall be used by and/or at the
sufferance of Lessee only for the purpose set forth in Article 11 above and for
no other purposes. Lessee shall not use or permit the use of the Demised
Premises in any manner that will tend to create waste or a nuisance, or will
tend to unreasonably disturb other Lessees in the Building or the Premises.
Lessee, its employees and all persons visiting or doing business with Lessee in
the Demised Premises shall be bound by and shall observe the reasonable rules
and regulations made by Lessor relating to the Demised Premises, the Building 

                                       12
<PAGE>   12

or the Premises of which notice in writing shall be given to Lessee, and all
such rules and regulations shall be deemed to be incorporated into and form a
part of this Lease.

     b. Lessee covenants throughout the Lease Term, at Lessee's sole cost and
expense, promptly to comply with all laws and ordinances and the orders, rules
and regulations and requirements of all federal, state and municipal governments
and appropriate departments, commissions, boards, and officers thereof, and the
orders, rules and regulations of the Board of Fire Underwriters where the
Demised Premises are situated, or any other body now or hereafter as well as
extraordinary, and whether or not the same require structural repairs or
alterations, which may be applicable to the Demised Premises, or the use or
manner of use of the Demised Premises. Lessee will likewise observe and comply
with the requirements of all policies of public liability, fire and all other
policies of insurance at any time in force with respect to the buildings and
improvements on the Demised Premises and the equipment thereof.

     c. In the event any Hazardous Material (hereinafter defined) is brought or
caused to be brought into or onto the Demised Premises, the Building or the
Premises by Lessee, Lessee shall handle any such material in compliance with all
applicable federal, state and/or local regulations. For purposes of this
Article, "Hazardous Material" means and includes any hazardous, toxic or
dangerous waste, substance or material defined as such in (or for purposes of)
the Comprehensive Environmental Response, Compensation, and Liability Act, and
so-called "Superfund" or "Superlien" law, or any federal, state or local statue,
law, ordinance, code, rule, regulation, order decree regulation, relating to, or
imposing liability or standards of conduct concerning, any hazardous, toxic or
dangerous waste, substance or material, as now or at any time hereafter in
effect. Lessee shall submit to Lessor on an annual basis copies of its approved
hazardous materials communication plan, OSHA monitoring plan, and permits
required by the Resource Recovery and Conservation Act of 1976, if Lessee is
required to prepare, file or obtain any such plans or permits. Lessee will
indemnify and hold harmless Lessor from any losses, liabilities, damages, costs
or expenses (including reasonable attorneys' fees) which Lessor may suffer or
incur as a result of Lessee's introduction into or onto the Demised Premises,
Building or Premises of any Hazardous Material. This Article shall survive the
expiration or sooner termination of this Lease.

       installed at Lessee's sole cost and expense, and in such manner,
       character and style as Lessor may approve in writing. Anything herein to
       the contrary notwithstanding, approval as to signs shall be subject to
       Lessor's approval which may be withheld in Lessor's sole discretion. In
       the event of a violation of the foregoing by Lessee, Lessor may remove
       the same without any liability and may charge the expense incurred by
       such removal to Lessee.

2.     Lessee, its employees, customers, invitees and guests shall not obstruct
       sidewalks, entrances, passages, corridors, vestibules, halls, or
       stairways in and about the Complex which are used in common with other
       tenants and their employees, customers, guests and invitees, and which
       are not a part of the Premises of Lessee. Lessee shall not place objects
       against glass partitions or doors or windows which would be unsightly
       from the Complex corridors or from the exterior of the Complex and will
       promptly remove any such objects upon notice from Lessor.

3.     Lessee shall not make excessive noises, cause disturbances or vibrations,
       use or operate any electrical or mechanical devices that emit excessive
       sound or other waves, disturbances or create obnoxious odors, nor operate
       any device/equipment for radio/television broadcasting or reception from
       or within the Complex or elsewhere and shall not place or install any
       projections, antennas, aerials or similar devices inside or outside the

6.     In no event shall Lessee bring into the Complex flammables, such as
       gasoline, kerosene, naphtha, benzene, explosives or any other article of

       comply with the provisions of this subparagraph, any insurance premium
       for all or any part of the Complex shall at any time be increased, Lessee
       shall make immediate payment of the whole of the increased insurance
       premium, without waiver of any of Lessor's other rights at law or in
       equity for Lessee's breach of this lease.

7.     Lessee shall comply with all applicable federal, state and municipal
       laws, ordinances and regulations, and building rules and shall not
       directly or indirectly make any use of the Premises which may be

       or property or may increase the cost of insurance or require additional
       insurance coverage.

8.     Lessor shall have the right to prohibit any advertising by Lessee which
       in Lessor's reasonable opinion tends to impair the reputation of the
       Complex or its desirability as a building complex for office/warehouse
       use, and upon written notice from Lessor, Lessee shall refrain from or
       discontinue such advertising.

9.     The Premises shall not be used for cooking (as opposed to heating of

       payment by Lessee. Upon termination of this Lease or of Lessee's
       possession, Lessee shall surrender all keys of the Premises and shall
       explain to Lessor all combination locks on safes, cabinets and vaults.
