holding over period. Except as otherwise agreed, any holding over with the
written consent of Landlord shall constitute Tenant a month-to-month lease. Upon
entry into a lease renewal following the payment of Holdover Rent, the Landlord
shall refund such holdover rent.

20.0 MINIMUM TEMPERATURE:

Tenant shall maintain a minimum temperature in the Demised Premises of 40
degrees during the Lease Term.

21.0 DEFAULT OF TENANT:

  a.   In the event of any failure of Tenant to pay any rental due hereunder
within ten (10) days after the same becomes due or any failure to perform any
other terms, conditions or covenants of this Lease to be observed or performed
by Tenant for more than thirty (30) days after written notice of such failure
shall have been given to Tenant, or if Tenant or an agent of Tenant shall
intentionally falsify any report required to be furnished to Landlord pursuant
to the terms of this Lease, or if Tenant or any guarantor of this Lease shall
become bankrupt or insolvent, or file any debtor proceedings or any person shall
take or have against Tenant or any guarantor of this Lease in any court pursuant
to any statute either of the United States or of any state a petition in
bankruptcy or insolvency or for reorganization or for the appointment of a
receiver or trustee of all or a portion of Tenant’s or any such guarantor’s
property, or if Tenant or any such guarantor’s property, or if Tenant or any
such guarantor makes an assignment for the benefit of creditors, or if Tenant
shall suffer this Lease to be taken under any writ of execution, then in any
such event Tenant shall be in default hereunder, and Landlord, in addition to
other rights or remedies it may have, shall have, upon receipt of an order so
stating from a court of competent jurisdiction, the immediate right of re-entry
and may in such event 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 Tenant, without being guilty of trespass.
    b.   Should Landlord elect to re-enter the Demised Premises, as herein
provided, or should it take possession of the Demised Premises pursuant to legal
proceedings, 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 for 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 Landlord in its sole discretion may deem advisable. In
such event Landlord shall undertake reasonable efforts to mitigate damages, it
being understood and agreed that reasonable efforts by the Landlord do not
include the expenditure of funds by Landlord for which reimbursement by Tenant
has not been made or assured or the reletting of the Demised Premises in lieu of
other

10

--------------------------------------------------------------------------------

 

      available premises owned by the Landlord or its owners and affiliates.
Upon each such subletting all rentals received by the Landlord from such
reletting shall be applied first to the payment of any indebtedness other than
rent due hereunder from Tenant to Landlord; second, to the payment of that
portion of any costs and expenses of such reletting amortized over the initial
term of the successor lease which is allocable to the remainder of the remaining
Term of this Lease, including reasonable brokerage fees and reasonable
attorney’s fees and costs of alterations and repairs made to the Demised
Premises in connection with such reletting., third, to the payment of the rent
due and unpaid hereunder, and the residue, if any shall be held by Landlord and
applied in 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 Tenant hereunder, Tenant, upon demand,
shall pay any such deficiency to Landlord. No such re-entry or taking possession
of the Demised Premises by Landlord shall be construed as an election on its
part to terminate this Lease unless a written notice of such intention be given
to Tenant or unless the termination thereof be decreed by a court of competent
jurisdiction. Notwithstanding any such reletting without termination, Landlord
may at any time after such re-entry and reletting elect to terminate this Lease
for such previous breach. Should Landlord at any time terminate this Lease for
any such breach, in addition to any other remedies it may have, it may recover
from Tenant all damages (excluding indirect or consequential damages) it may
incur by reason of such breach, including the cost of recovering the Demised
Premises, reasonable attorney’s fees and costs incurred in enforcing Landlord’s
remedies hereunder, the unamortized portion of any leasehold improvements made
by Landlord for Tenant 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 stated
term, all of which amounts shall be immediately due and payable from Tenant to
Landlord subject to a reasonable present value discount at the “prime” or
“reference” rate then announced at Wells Fargo Bank, N.A., Minneapolis office,
or its successors and assigns (the “Prime Rate”).     c.   Landlord may, at its
option, instead of exercising any other rights or remedies available to it in
this Lease or otherwise by law, statute or equity, spend such money as is
reasonably necessary to cure any default of Tenant herein and the amount so
spent, and costs incurred, including reasonable attorney’s fees in curing such
default, shall be paid by Tenant, as 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 or 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 the Tenant to be kept or performed, and a breach shall be
established, Tenant shall pay to Landlord all reasonable expenses incurred
therefor, including reasonable attorney’s fees and costs, together with interest
on all such expenses at the rate of four percent (4%) per annum in excess of the
Prime Rate (the “Default Rate”) from the date of such breach of the covenants of
this Lease.     e.   In the event of a default by Tenant hereunder, except as
otherwise expressly provided herein, Tenant waives any demand for possession of
the Demised Premises, and any demand for payment of rent and any notice of
intent to re-enter the Demised Premises, or of intent to terminate this Lease,
other than the notices above provided in this Article, and any other notice or
demand prescribed by any applicable statutes or laws.

11

--------------------------------------------------------------------------------

 

  f.   No remedy herein or elsewhere in this Lease or otherwise by law, statute
or equity, conferred upon or reserved to Landlord or Tenant 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.

22.0 DEFAULT OF LANDLORD:

The failure of Landlord to perform or observe any of the covenants, provisions
or conditions contained in this Lease on its part to be performed or observed
within thirty (30) days after written notice of default shall be considered a
“Landlord Default” for purposes of this Lease. In the event of a Landlord
Default, Tenant may, in addition to any other rights and remedies allowed by
applicable law, and except as otherwise expressly set forth herein, cause such
default to be cured and deduct from its next due installments of Rent hereunder,
all reasonable costs and expenses incurred by Tenant in doing so.
Notwithstanding the foregoing to the contrary, in the event that Landlord shall,
within thirty (30) days after receipt of any notice of default from Tenant,
provide notice to Tenant that Landlord in good faith disputes that Landlord is
in default in the performance of any obligation hereunder (a “Dispute Notice”),
Tenant shall not offset or deduct any amounts from any installments of Rent
unless and until such bona fide dispute shall have been resolved in Tenant’s
favor under a “reference proceeding” in accordance with the provisions set forth
below.

Such reference proceeding shall be conducted in accordance with the procedures
set forth below for a determination which will be binding upon the parties, and
subject to an appeal only to the extent a binding arbitrator’s award would be
appealable under the rules of the American Arbitration Association (“AAA”). The
parties agree specifically as to the following:

  (i)   Within fifteen (150) business days after service of a Dispute Notice,
the parties will agree upon a single neutral referee from among a pool of
mediators and other “neutrals” provided by the Ramsey County Bar Association who
will then try all issues, whether of fact or law, and then report a finding
judgment thereon. If the parties are unable to agree upon a referee, either
party may seek appointment of a referee by a judge of the Ramsey County District
Court.     (ii)   The compensation of the referee shall be such charge as is
customarily charged by the referee for like services. The cost of such
proceedings will initially be borne equally by the parties. However, the
prevailing party in such proceedings shall be entitled, in addition to all other
costs, to recover its contribution for the cost of the reference as an item of
damages and/or recoverable costs.     (iii)   If a reporter is requested by
either party, then a reporter will be present at all proceedings, and the fees
of such report shall be borne by the party requesting such reporter. Such fees
will be an item of recoverable costs. Only a party will be authorized to request
a reporter.     (iv)   The referee will apply the substantive law of Minnesota
in deciding the issues to be heard.     (v)   Notice of any motions before the
referee will be given, and all matters shall be set at the convenience of the
referee.     (vi)   The parties agree that they will in good faith endeavor to
cause any such dispute to be decided within three (3) months. The date of
hearing for any proceeding will be determined by agreement of the parties and
the referee, or if the parties cannot agree, then by the referee.

12

--------------------------------------------------------------------------------

 

  (vii)   The referee shall have the power to make a determination as to the
existence of a default on the part of the Landlord, the reasonable costs to cure
such default and Tenant’s right to recover the cost of cure from the Landlord.
Consequential and incidental damages shall not be recoverable in these
proceedings.

23.0 EMINENT DOMAIN:

In the event of any eminent domain of condemnation proceeding or private sale in
lieu thereof in respect to the Building during the term thereof, the following
provisions shall apply:

  a.   If the whole of the Building shall be acquired or condemned by eminent
domain for any public or quasi-public purpose, the term of this lease shall
cease and terminate as of the date possession shall be taken in such proceedings
and all rentals shall be paid up to that date.     b.   If any part constituting
less than the whole of the Building 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 Demises Premises unsuitable for
the business of the Tenant, in the reasonable opinion of Tenant, 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
Building which shall not materially affect the Demised Premises so as to render
the Demised Premises unsuitable for the business of the Tenant, in the
reasonable opinion of the Tenant, this Lease shall continue in full force and
effect with a proportionate abatement of the Base Rent and Additional Rent based
on the portion, if any of the Demised Premises taken. Landlord 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, Landlord shall give written notice to Tenant, within 30 days
following the date possession shall be taken by the condemning authority, of
Landlord’s intention to restore. Upon Landlord’s notice of election to restore,
Landlord shall commence restoration and shall restore the Building and the
Demised Premises with reasonable promptness, subject to delays beyond Landlord’s
control and delays in the making of condemnation or sale proceeds adjustments by
Landlord; and Tenant shall have no right to terminate this Lease except as
provided above. Upon completion of such restoration, the rent shall be equitably
adjusted based upon the portion, if any, of the Demised Premises restored.    
c.   Except as set forth in subsection (d) below, in the event of any
condemnation or taking as aforesaid, whether whole or partial, the Tenant shall
not be entitled to any part of the award paid for such condemnation and Landlord
is to receive the full amount of such award, the Tenant hereby expressly waiving
any right to claim to any part thereof.     d.   Although all damages in the
event of any condemnation shall belong to the Landlord whether such damages are
awarded as compensation for diminution in value of the leasehold or to the fee
of the Demised Premises, Tenant shall have the right to claim and recover from
the condemning authority, but not from Landlord, such compensation as may be
separately awarded or recoverable by Tenant in Tenant’s own right on account of
any and all damage to Tenant’s business by reason of the condemnation and for or
on account of any cost or loss to which Tenant might be put in removing Tenant’s
merchandise, furniture, fixtures, leasehold

13

--------------------------------------------------------------------------------

 

      improvements and equipment, or for moving expenses. However, Tenant shall
have no claim against Landlord or make any claim with the condemning authority
for the loss of its leasehold estate, any unexpired term or 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.

24.0 RULES AND REGULATIONS. INTENTIONALLY OMITTED

25.0 CONDITION AFFECTING HEALTH AND SAFETY:

In the event that any condition not caused by Tenant, its employees, agents or
contractors, exists or arises in the Building or on the Property which has been
determined by a qualified third party to constitute a material risk to the
health or safety of Tenant’s employees, invitees or licensees and Tenant has
provided Landlord with written notice of such condition and the third party
opinion with respect thereto and, as a result thereof, Tenant, in its reasonable
business discretion, elects to cease the use of that portion of the Demised
Premises which has been determined by such third party to constitute such risk.
Base and Additional Rent shall abate equitably until Landlord shall correct such
condition. In addition, if Landlord fails to correct such condition within one
hundred eighty (180) days after written notice thereof from Tenant, Tenant shall
have the right to terminate this Lease by written notice to Landlord.

26.0 DAMAGE OR DESTRUCTION:

In the event of any damage or destruction to the Premises by fire or other cause
during the term hereof, the following provisions shall apply:

  a.   If the Building is damaged by fire or any other cause to such extent that
the cost of restoration, as reasonably estimated by Landlord, will equal or
exceed thirty percent (30%) of the replacement value of the Building (exclusive
of foundations) just prior to the occurrence of the damage, then Landlord may,
not later than the sixtieth (60th) day following the damage, give Tenant written
notice of Landlord’s election to terminate this Lease.     b.   If the cost of
restoration as estimated by Landlord 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 Tenant, then Tenant may, no later than
the sixtieth (60th) day following the damage, give Landlord a written notice of
election to terminate this Lease.     c.   If the cost of restoration as
reasonably estimated by Landlord shall amount to less than thirty percent (30%)
of said replacement value of the Building, or if, despite the cost, Landlord
does not elect to terminate this Lease, Landlord shall restore the Building and
the Demised Premises with reasonable promptness, subject to delays beyond
Landlord’s control and delays in the making of insurance adjustments by
Landlord; and Tenant shall have no right to terminate this Lease except as
herein provided. Landlord shall not be responsible for restoring or repairing
leasehold improvements of the Tenant Notwithstanding the foregoing to the
contrary, if Landlord fails to complete such restoration and provide to Tenant a
Certificate of Occupancy with respect to the Demised Premises issued by the City
of Roseville, Minnesota within one hundred eighty (180) days after the date of
such damage, Tenant shall have the option to terminate this Lease by written
notice to Landlord (a “Tenant Termination Notice”); provided, however, that such
Tenant Termination Notice shall not effective if Landlord completes the

14

--------------------------------------------------------------------------------

 

      required restoration work and delivers to Tenant the required Certificate
of Occupancy within thirty (30) days after the date of the Tenant Termination
Notice.     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. Tenant shall have no
claim against Landlord 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
Tenant, its employees, contractors or licensees, in which case there shall be no
abatement of rent, 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.

27.0 CASUALTY INSURANCE:

  a.   Landlord 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 Landlord shall not be obligated to insure any furniture,
equipment, machinery, goods or supplies not covered by this Lease which Tenant
may bring upon the Demised Premises or any additional improvements which Tenant
may construct or install on the Demised Premises.     b.   Tenant shall not
knowingly 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 and will in any
event remove any such goods or case any such activity within fifteen (15) days
after receipt of notice from Landlord with respect thereto.     c.   Landlord
hereby waives and releases all claims, liabilities and causes of action against
Tenant and its agents, servants and employees for loss of damage to, or
destruction of, the Building or any portion thereof, including the buildings and
other improvements situated thereon, 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. Likewise, Tenant hereby waives
and releases all claims, liabilities and causes of action against Landlord and
its agents, servants and employees for loss of damage to, or destruction of, any
of the improvements, fixtures, equipment, supplies, merchandise and other
property, whether that of Tenant or of others in, upon or about the Premises
resulting from fire, explosion or the other perils included in standard coverage
insurance, whether caused by the negligence of any of said persons or otherwise.
The waiver shall remain in force whether or not the Lessee’s insurer shall
consent thereto.     d.   In the event that the use of the Demised Premises by
Tenant increases the premium rate for insurance carried by Landlord on the
improvements of which the Demised Premises are a part, Tenant shall pay
Landlord, upon demand, the amount of such premium increase. Landlord represents
that the use of the Demised Premises by the prior tenant thereof did not cause
such increase in Landlord’s insurance premiums. If Tenant installs any
electrical equipment that

15

--------------------------------------------------------------------------------

 

      overloads the power lines to the building or its wiring, Tenant 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.

28.0 COVENANTS TO HOLD HARMLESS:

Unless the liability for damage or loss is caused by the negligence of Landlord,
its agents, employees or contractors, Tenant shall hold harmless Landlord from
any liability for damages to any person or property in or upon the Demised
Premises and the Building, including the person and property of Tenant and its
employees and all persons in the Building at its or their invitation or
sufferance, and from all damages resulting from Tenant’s failure to perform the
covenants of this Lease. Unless the liability for damage or loss is caused by
the negligence of Tenant, its agents, employees or contractors, Landlord shall
hold harmless Tenant from any liability for damages to any person or property in
or upon the Building (excluding the Demised Premises) or the Property, including
the person and property of Landlord and its employees and all persons in the
Building or on the Property. All property kept, maintained or stored on the
Demised Premises shall be so kept, maintained or stored at the sole risk of
Tenant. Tenant 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
Tenant in or about the Demised Premises, and not furnished on order of Landlord,
which may be secured by any mechanic’s materialmen’s or other lien to be
discharged at the time performance of any obligation secured thereby matures,

said stay expires, then and in each such event, Tenant shall forthwith pay and
discharge said judgment. Landlord shall have the right to post and maintain on
the Demised Premises, notices of non-responsibility under the laws of the State
of Minnesota.

29.0 NON-LIABILITY:

30.0 SUBORDINATION:

This Lease shall be subordinated to any mortgage 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, so long as
such holder shall agree in writing that it shall not disturb the possession and
other rights of Tenant under this Lease so long as Tenant is not in default
hereunder beyond any applicable cure periods. In the event of execution by
Landlord after the date of this Lease of any such mortgage, renewal, replacement
or extension, Tenant agrees to execute a subordination agreement (an “SNDA”)
with the holder thereof which agreement shall provide that:

this Lease, or if the Building comes into custody or possession of a mortgagee
or any other party whether because of a mortgage foreclosure, or otherwise,

Landlord hereunder; provided, however, Tenant’s peaceable possession will not be
disturbed so long as Tenant faithfully performs its obligations under this
Lease. Tenant shall execute, on demand, any attornment agreement required by any
such party to be executed, containing such provisions as such party may
reasonably require so long as the transferee shall assume in writing the
obligations of Landlord hereunder. Landlord shall have no further obligations
under this Lease after any such assignment.

32.0 NOVATION IN THE EVENT OF 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

17

--------------------------------------------------------------------------------

 

33.0 QUIET ENJOYMENT:

Landlord warrants that it has full right to execute and to perform this Lease
and to grant the estate demised, and that Tenant, upon payment of the rents and
other amounts due and the performance of all the terms, conditions, covenants
and agreements on Tenant’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.

34.0 RECORDING:

Tenant shall not record this Lease without the written consent of Landlord.
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

  a.   The Lease does not create the relationship of principal and agent or of
partnership or of joint venture or of any association between Landlord and
Tenant, the sole relationship between the parties hereto being that of Landlord
and Tenant.     b.   No waiver of any default of Tenant hereunder shall be
implied from any omission by Landlord 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
Landlord shall not then be construed as a waiver of a subsequent breach of the
same covenant, term or condition. The consent or approval by Landlord of any act
by Tenant requiring Landlord’s consent or approval shall not waive or render
unnecessary Landlord’s consent to or approval of any subsequent similar act by
Tenant. No action required or permitted to be taken by or on behalf of Landlord
under the terms or provisions of this Lease shall be deemed to constitute an
eviction or disturbance of Tenant’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.     c.   This Lease and the exhibits, if any,
attached hereto and forming a part hereof, constitute the entire agreement
between Landlord and Tenant affecting the Demised Premises and there are no

18

--------------------------------------------------------------------------------

 

      other agreements, either oral or written, between them other than herein
set forth. No subsequent alteration, amendment, change or addition to this Lease
shall be binding upon Landlord or Tenant unless reduced to writing and executed
in the same form and manner in which this Lease is executed.     d.   If any
agreement, covenant or condition of this Lease or the application thereof to any
person or circumstance 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.     e.   The captions are inserted only as a
matter of convenience and for reference, and in no way define, limit or describe
the scope of this Lease nor the intent or any provision thereof.     f.  
Submission of this instrument to Tenant or proposed Tenant or his agents or
attorneys for examination, review, consideration or signature does not
constitute or imply an offer to lease, reservation of space, or option to lease,
and this instrument shall have no binding legal effect until execution hereof by
both Landlord/Owner and Tenant or its agents.

38.0 LITIGATION COSTS:

If either party hereto initiates litigation (including without limitation a
reference proceeding under Section 22 hereof) to enforce the provisions of this
Lease against the other party, the prevailing party in such litigation shall be
entitled to reimbursement from the non-prevailing party of all reasonable and
documented costs and expenses, including reasonable attorneys’ fees, paid or
incurred by the prevailing party in connection with such litigation. The term
“prevailing party” shall be defined to mean the party whose position in such
litigation is substantially upheld in a final, non-appealable judgment rendered
in such action.

39.0 TENANT CONTENCIES:

The obligations of Tenant hereunder shall be contingent upon the following:

  (i)   Tenant obtaining at Landlord’s costs (not to exceed $2,000.00), a Phase
I Environmental Site Assessment of the Building and the Property prepared by an
environmental consultant reasonably acceptable to Tenant (the “Phase I Report”),

40.0 TENANT IMPROVEMENT ALLOWANCE:

Landlord will provide a Fifty Thousand and 00/100 Dollar ($50,000.00) cash

Allowance”). The Tenant Improvement Allowance shall be used to reimburse Tenant
for the cost of improvements to the Demised Premises which have been approved by
Landlord, either prior to or after the Commencement Date, upon presentation of
