2.  LEASE OF PREMISES; RENT

2.1.Lease of Premises for Lease Term.Landlord hereby
leases the Premises to Tenant, and Tenant hereby rents the Premises from Landlord, for the Term and subject to the conditions of this Lease.

2.2.Renewal Term.Provided that this Lease is in full
force and effect and Tenant is not in default under the terms hereof, and the Premises are occupied by the Tenant named herein, Landlord hereby grants to Tenant the option to extend the Term of this
Lease (the "Renewal Option") on the same terms, conditions and provisions as contained in this Lease, except as otherwise provided herein, for two periods of five (5) years each (a "Renewal
Term"). The Initial Term, as extended by any Renewal Term is herein referred to as the Lease Term. In order to exercise the Renewal Option, Tenant must give Landlord written notice thereof not less
than two hundred seventy (270) days prior to the Expiration Date of the Term, or the first Renewal Term, as the case may be.

---



2.3.Types of Rental Payments.Commencing on the Rent
Commencement Date, Tenant shall pay rents of (a) annual base rent (as set forth inSection 1.12hereof), payable in monthly installments,
in advance, on the first day of each and every calendar month during the term of this Lease (the "Base Rent"); and (b) all costs, expenses and charges of every kind or nature relating to, or
incurred in connection with, the ownership and operation of the Premises and the Property and that are attributable to, or become due, during the Term, including, but not limited to, the cost of
insurance underSection 10.1hereof (collectively, "Additional Rent"); (c) structural, parking lot and roof replacement reserves in
amounts and at times to be determined by Landlord and Tenant; which Landlord presently estimates to be $.10.15 per rentable square foot annually. In the event any monthly installment of
Base Rent or Additional Rent, or both, is not paid within ten (10) days of the date when due, Tenant shall pay a late charge in an amount equal to the late charge, if any, assessed by
Landlord's lender on the Mortgage encumbering the Property (the "Late Charge"). The Late Charge, Base Rent and Additional Rent shall collectively be referred to as "Rent", and shall be payable to Hoyt
Properties Inc., 708 South Third Street, Suite 108, Minneapolis, MN 55415 (or such other entity designated as Landlord's management agent, if any, and if Landlord so appoints such a management
agent, the "Agent"), or pursuant to such other directions as Landlord shall designate in this Lease or otherwise in writing.

2.4.Covenants Concerning Rental Payments.Tenant shall
pay the Rent promptly when due, without notice or demand, and without any abatement, deduction or setoff, except as may otherwise be expressly and specifically provided in this Lease. No payment by
Tenant, or receipt or acceptance by Landlord, of a lesser amount than the correct Rent shall be deemed to be other than a payment on account, nor shall any endorsement or statement on any check or
letter accompanying any payment be deemed an accord or satisfaction, and Agent or Landlord may accept such payment without prejudice to its right to recover the balance due or to pursue any other
remedy available to Landlord. If the Commencement Date occurs on a day other than the first day of a calendar month, the Rent due for the first calendar month of the Term shall be prorated on a per
diem basis, and the term shall be extended to terminate at the end of the calendar month in which the Expiration Date stated inSection 1.6above
occurs.

3.  TAXES

Tenant agrees to pay as Additional Rent for the Premises (i) all governmental taxes, assessments, fees and charges of every kind or nature (other than
Landlord's income taxes), whether general, special, ordinary or extraordinary, due at any time, or from time to time during the Term, and any renewals or extensions thereof, in connection with the
ownership, leasing or operation of the Premises, or of the personal property and equipment located therein or used in connection therewith, and (ii) any reasonable expenses incurred by Landlord
in contesting such taxes or assessments and/or the assessed value of the Premises (the "Taxes"). All such Taxes shall be paid by Tenant before they become delinquent. The Taxes for the first and last
years of the Term will be appropriately prorated. If any
special assessments levied against the Premises are payable in installments, Tenant shall be responsible only for those installments that are due and payable during the Term. For purposes hereof,

2

---

Taxes for any year shall be Taxes that are due for payment or paid in that year, rather than taxes that are assessed or become a lien or accrue during such year. Tenant, at its cost and expense, shall
have the right to contest the Taxes levied against the Leased Premises or the valuation assessed there-against, through the commencement of appropriate proceedings (herein "Tax Contest"). Landlord
shall cooperate with Tenant in prosecuting any Tax Contest and shall execute any documents reasonably requested by Tenant. Any refund given in such Tax Contest proceeding shall be the sole and
exclusive property of Tenant.

Tenant
may pay such Taxes directly to the taxing authority. Any Taxes which Tenant is required to pay shall be paid no later than the date on which such taxes are due. If Tenant fails
to pay any Taxes which it is required to pay within the time period provided above, Landlord may, at its option, pay said Taxes, together with any and all penalties and interest, and said amount shall
become immediately due and payable as Additional Rent.

4.  USE OF PREMISES; SECURITY DEPOSIT

4.1.Use of Premises.The Premises shall be used for
the purpose(s) set forth inSection 1.8above and for no other purpose whatsoever. Tenant shall not, at any time, use or occupy, or suffer or

Property; (b) cause, or be liable to cause, injury to the Property or any equipment, facilities or systems therein; (c) constitute a violation of the laws and requirements of any public
authority or the requirements of insurance bodies, including any covenant, condition or restriction affecting the Property; (d) exceed the load bearing capacity of the floor of the Premises; or

size or character to any portion of the Property, without prior written approval of Landlord, which approval shall not be unreasonably withheld or delayed. Tenant's signage shall comply with all laws,

2000 deposited with Landlord the sum set forth inSection 1.11above, in cash (the "Security"), representing security for the performance by
Tenant of the covenants and obligations hereunder. The Security shall be held by Landlord, without interest, in favor of Tenant until the Commencement Date under the Lease, at which time the Security
shall be refunded immediately to Tenant without notice or demand. In the event the Security is not refunded by Landlord on the Commencement Date, Tenant shall have the right to offset the Security
against installments of Rent as they become due under this Lease, until the Security is exhausted.

expressly provided inExhibit "B", Landlord shall not be liable to Tenant if Landlord fails to deliver possession of the Premises to Tenant on or before
the Delivery Date (as defined inExhibit "B"hereto). The obligations of Tenant under the Lease shall not thereby be affected, except that the
Commencement Date shall be delayed to the extent expressly provided inExhibit "B".

6.  SUBORDINATION; NOTICES TO SUPERIOR LESSORS AND MORTGAGEES

6.1.Subordination.Provided that Tenant is provided
with a reasonable and customary subordination, nondisturbance and attornment agreement duly executed by the holder of any mortgage or deed of trust or the Landlord pursuant to any ground lease, this
Lease shall be subject and subordinate at all times to all ground leases or underlying leases which may now exist or hereafter be executed affecting the Premises and/or the land upon which the
Premises and Property are situated and to any mortgage or deed of trust which may now exist or be placed upon the Property, land, ground leases or underlying leases, or Landlord's interest or estate
in any of said items, which is specified as security. Notwithstanding the foregoing, Landlord shall have the right to subordinate or cause to be subordinated any such ground leases or underlying
leases or any such liens to this Lease. Tenant shall execute and deliver, upon demand by Landlord and in the form reasonably requested by Landlord, any additional documents evidencing the priority or
subordination of this Lease with respect to any such ground leases or underlying leases or any such mortgage or deed of trust.

6.2.Estoppel Certificates.Tenant agrees, from time to
time and within ten (10) days after request by Landlord, to deliver to Landlord, or Landlord's designee, an estoppel certificate stating such matters pertaining to this Lease as may be
reasonably requested by Landlord. Failure by Tenant to timely execute and deliver such certificate shall constitute an acceptance of the Premises and acknowledgment by Tenant that the statements
included therein are true and correct without exception. Landlord and Tenant intend that any statement delivered pursuant to this section may be relied upon by any prospective purchaser or mortgagee
of the Property or of any interest therein or any other Landlord designee.

6.3.Transfer by Landlord.After the Commencement Date,
in the event of a sale or conveyance by Landlord of the Property, the same shall operate to release Landlord from any future liability for any of the covenants or conditions, express or implied,
herein contained in favor of Tenant, and in such event Tenant agrees to look solely to Landlord's successor in interest with respect thereto and agrees to attorn to such successor.

7.  QUIET ENJOYMENT

Subject to the provisions of this Lease, so long as Tenant pays all of the Rent and performs all of its other obligations hereunder, Tenant shall not be
disturbed in its possession of the Premises by
Landlord, Agent or any other person lawfully claiming through or under Landlord. This covenant shall be construed as a covenant running with the Property and is not a personal covenant of Landlord.

8.  ASSIGNMENT, SUBLETTING AND MORTGAGING

8.1.Prohibition.Tenant acknowledges that this Lease
and the Rent due under this Lease have been agreed to by Landlord in reliance upon Tenant's reputation and creditworthiness and upon the continued operation of the Premises by Tenant for the
particular use set forth inSection 4above; therefore, Tenant shall not, whether voluntarily, or by operation of law, or otherwise:
(a) assign or otherwise transfer this Lease; (b) sublet the Premises or any part thereof, or allow the same to be used or occupied by anyone other than Tenant;, if Tenant shall not
remain liable to Landlord for all Tenant obligations, including those underSection 2.3of the Lease; or (c) mortgage, pledge, encumber,
or otherwise hypothecate this Lease or the Premises, or any part thereof, in any manner whatsoever,

---

without in each instance obtaining the prior written consent of Landlord, which consent may be given or withheld in Landlord's sole, but reasonable, discretion. Any purported assignment, mortgage,
transfer, pledge or sublease made without the prior written consent of Landlord shall be absolutely null and void. No assignment of this Lease shall be effective and valid unless and until the
assignee executes and delivers to Landlord any and all documentation reasonably required by Landlord in order to evidence assignee's assumption of all obligations of Tenant hereunder. Any consent by
Landlord to a particular assignment, sublease or mortgage shall not constitute consent or approval of any subsequent assignment, sublease or mortgage, and Landlord's written approval shall be required
in all such instances. Any consent by Landlord to any assignment or sublease shall not be deemed to release Tenant from its obligations hereunder and Tenant shall remain fully liable for performance
of all obligations under this Lease.

8.2.Rights of Landlord.If this Lease is assigned, or
if the Premises (or any part thereof) are sublet or used or occupied by anyone other than Tenant, whether or not in violation of this Lease, Landlord or may (without prejudice to, or waiver of its
rights), collect Rent from the assignee, subtenant or occupant. Landlord or may apply the net amount collected to the Rent herein reserved, but no such assignment, subletting, occupancy or collection
shall be deemed a waiver of any of the provisions of thisSection 8.

8.3.Permitted Transfers.The provisions of Section 8.1(a)shall apply to a transfer of a majority of the voting
stock of Tenant or to any other change in voting control of Tenant whether
effectuated in one (1) or more transactions, as if such transfer were an assignment of this Lease; but said provisions shall not apply to such a transfer if the successor to Tenant (or any
party remaining liable for the obligations of Tenant hereunder) (i) has a net worth at least equal to the net worth of Tenant as of the Commencement Date or (ii) is capable of satisfying
Tenant's obligations hereunder, in Landlord's reasonable judgment. Any such permitted transferee shall execute and deliver to Landlord any and all documentation reasonably required by Landlord in
order to evidence assignee's assumption of all obligations of Tenant hereunder.

9.  COMPLIANCE WITH LAWS

9.1.Compliance with Laws.As of the Commencement Date
and thereafter, Tenant shall, at its sole expense (regardless of the cost thereof), comply with all local, state and federal laws, rules, regulations and requirements now or hereafter in force and all
judicial and administrative decisions pertaining thereto (collectively, "Laws") pertaining to the Premises or Tenant's use thereof, including, without limitation, any restrictions of record affecting
the Property, any and all laws pertaining to Hazardous Materials (as hereinafter defined) or which otherwise deal with or relate to air or water quality, air emissions, soil or ground conditions or
other environmental matters of any kind (collectively, "Environmental Laws") and the Americans with Disabilities Act, 42 U.S.C. §§ 12101-12213, whether or
not any of the foregoing were in effect at the time of the execution of this Lease. Landlord warrants that the Premises will on the Commencement Date comply with all Laws including the Americans with
Disabilities Act. If any license or permit is required for the conduct of Tenant's business in the Premises, Tenant, at its expense, shall procure such license prior to the Commencement Date, and
shall maintain in good standing such license or permit. Tenant shall give prompt notice to Landlord of any written notice it receives of the alleged violation of any law or requirement of any
governmental or administrative authority with respect to the Premises or the use or occupation thereof. The judgment of any court of competent jurisdiction, or the admission of Tenant in any action or
proceeding against Tenant, whether Landlord is a party thereto or not, that any such Law pertaining to the Premises has been violated, shall be conclusive of that fact as between Landlord and Tenant.

9.2.Hazardous Materials.If during the Term (or any
extension thereof) any Hazardous Material (defined below) is generated, transported, stored, used, treated or disposed of at, to, from, on or in the

5

Premises: (i) Tenant shall, at its own cost, at all times comply (and cause all others to comply) with all laws (federal, state or local) relating to Hazardous Materials, including, but not
limited to, all
Environmental Laws, and Tenant shall further, at its own cost, obtain and maintain in full force and effect at all times all permits and other approvals required in connection therewith;
(ii) Tenant shall promptly provide Landlord or Agent with complete copies of all communications, permits or agreements with, from or issued by any governmental authority or agency (federal,
state or local) or any private entity relating in any way to the presence, release, threat of release, or placement of Hazardous Materials on or in the Premises or any portion of the Property, or the
generation, transportation, storage, use, treatment, or disposal at, on, in or from the Premises, of any Hazardous Materials; (iii) Landlord, Agent and their respective agents and employees
shall have the right to enter the Premises and/or conduct appropriate tests for the purposes of ascertaining Tenant compliance with all applicable laws (including Environmental Laws), rules or permits
relating in any way to the generation, transport, storage, use, treatment, disposal or presence of Hazardous Materials on, at, in or from the Premises, the Property or any portion thereof; and
(iv) upon reasonable written request by Landlord or Agent, Tenant shall provide Landlord with the results of appropriate tests of air, water or soil to demonstrate that Tenant complies with all
applicable laws, rules or permits relating in any way to the generation, transport, storage, use, treatment, disposal or presence of Hazardous Materials on, at, in or from the Property or any portion
thereof. ThisSection 9.2does not authorize the generation, transportation, storage, use, treatment or disposal of any Hazardous Materials at,
to, from, on or in the Premises in contravention of thisSection 9. Tenant covenants to investigate, clean up and otherwise remediate any release
of Hazardous Materials caused, contributed to or created by (i) Tenant or any of Tenant's officers, directors, invitees, agents, employees, contractors or representatives ("Tenant's Parties")
at its sole expense during the Term. Such investigation and remediation shall be performed only after Tenant has obtained Landlord's prior written consent; provided, however, that Tenant shall be
entitled to respond immediately to an emergency without first obtaining such consent. All remediation shall be performed in strict compliance with Environmental Laws and to the satisfaction of
Landlord. Tenant shall be liable for any and all conditions covered hereby, and for all costs relating thereto, which were caused or created by Tenant or any of Tenant's Parties. Tenant shall not
enter into any settlement agreement, consent decree or other compromise with respect to any claims relating to any Hazardous Materials in any way connected to the Premises without first obtaining
Landlord's written consent and affording Landlord the reasonable opportunity to participate in any such proceedings. As used herein, the term "Hazardous Materials" shall mean any waste, material or
substance (whether in the form of liquids, solids or gases, and whether or not air-borne) which is or may be deemed to be or include a pesticide, petroleum, asbestos, polychlorinated
biphenyl, radioactive material, urea formaldehyde or any other pollutant or contaminant which is or may be deemed to be hazardous, toxic, ignitable, reactive, corrosive, dangerous, harmful or
injurious, or which presents a risk to public health or to the environment, and which is or becomes regulated by any Environmental Law.

claims which might give rise to a right of subrogation by any insurance carrier. The coverage obtained by each party pursuant to this Lease shall include, without limitation, a waiver of subrogation

coverages as required inSection 10.2(ii)above) and workers compensation insurance. Such insurance policies shall satisfy the obligations
imposed underSection 10.2.After obtaining Landlord's approval to the Alterations, Tenant shall give Landlord at least five (5) days'

claims for labor and material furnished to the Premises in connection with the Alterations. Tenant shall not permit any mechanics or materialmen's liens to attach to the Premises, the Property, or

may procure (for Landlord's benefit), a bond or other protection against any such lien or encumbrance. In the event Tenant has not so performed, Landlord may, at its option, pay and discharge such
liens and Tenant shall be responsible to reimburse Landlord, on demand and as Additional Rent under this Lease, for all costs and expenses incurred in connection therewith, together with interest
thereon at the rate set forth inSection 22.3below, which expenses shall include reasonable fees of attorneys of Landlord's choosing, and any
costs in posting bond to effect discharge or release of the lien as an encumbrance against the Premises or the Property.

(collectively, the "Tenant's Property") shall be and shall remain the property of Tenant and may be removed by Tenant at any time during the Term, provided Tenant repairs or pays the cost of repairing
any damage to the Premises or to the Property resulting from the installation and/or removal thereof. At or before the Expiration Date, or the date of any earlier termination, Tenant, at its expense,
shall remove from the Premises all of Tenant's Property and any Alterations (except such items thereof as Landlord shall have expressly permitted, in writing, to remain, which property shall become
the property of Landlord), and Tenant shall repair any damage to the Premises or the Property
resulting from any installation and/or removal of Tenant's Property. Any other items of Tenant's Property that shall remain in the Premises after the Expiration Date, or following an earlier

preventative maintenance and service contract with a reputable service provider for maintenance of the HVAC systems of the Premises. Without limiting the generality of the foregoing, any repairs or
replacements required to be made by Tenant including repairs to the mechanical, electrical, sanitary, HVAC, or other systems of the Premises shall be performed, at Tenant's expense, by appropriately
licensed contractors. All such repairs or replacements shall be subject to the supervision and control of Landlord, and all repairs and replacements shall be made with materials of equal or better
quality than the items being repaired or replaced. After Substantial Completion of the Premises, Landlord shall transfer to Tenant all warranties Landlord has received with respect to any and all
work, maintenance and service for which Tenant is responsible under the terms and conditions of this Lease. Tenant shall comply with all post-construction requirements including those

15. INVOLUNTARY CESSATION OF SERVICES

Landlord shall have no liability or responsibility for a cessation of services to the Premises or to the Property that occurs as a result of causes beyond
Landlord's reasonable control. No such interruption of service shall be deemed an eviction or disturbance of Tenant's use and possession of the Premises or any part thereof, or render Landlord liable
to Tenant for damages, or relieve Tenant from performance of Tenant's obligations under this Lease, including, but not limited to, the obligation to pay Rent; provided, however, that if any
interruption of services persists for a period in excess of five (5) consecutive business days Tenant shall, as Tenant's sole remedy, be entitled to a proportional abatement of Rent to the
extent, if any, of any actual loss of use of the Premises by Tenant.

of the Property or providers of capital to Landlord and its affiliates; and (b) to make such repairs, alterations, additions and improvements in or to the Premises and/or in or to the Property
or its facilities and equipment as Landlord is required or

9

---

desires to make. Landlord and Agent shall be allowed to take all materials into and upon the Premises that may be required in connection with any repairs, alterations, additions or improvements,
without any liability to Tenant and without any reduction or modification of Tenant's covenants and obligations hereunder; provided, however, that Landlord shall use reasonable efforts to avoid
interference with Tenant's business operations and Tenant's occupancy and use of the Premises. Additionally, Landlord and Agent shall have the following rights exercisable, without notice to Tenant,
without liability to Tenant, and without being deemed an eviction or disturbance of Tenant's use or possession of the Premises or giving rise to any claim for setoff or abatement of Rent:
(i) to designate and approve, prior to installation, all types of signs; (ii) to have pass keys, access cards, or both, to the Premises; and (iii) to decorate, remodel, repair,
alter or otherwise prepare the Premises for reoccupancy at any time after Tenant vacates or abandons the Premises for more than thirty (30) consecutive days or with no intention of reoccupying
the Premises. During the period of six (6) months prior to the Expiration Date (or at any time, if Tenant has vacated or abandoned the Premises or is otherwise in default under this Lease),
Landlord and its agents may exhibit the Premises to prospective tenants and erect a "For Lease" sign thereon.

17. NON-LIABILITY AND INDEMNIFICATION

17.1.Non-Liability.Except as provided in Section 17.2.2, Landlord or its affiliates, owners, partners, directors,
 officers, agents and employees shall not be liable to Tenant for any
loss, injury, or damage, to Tenant or to any other person, or to its or their property, irrespective of the cause of such injury, damage or loss. Further, except as provided in Section 17.2.2,

under Tenant; (c) any latent defect in the Premises or the Property; (d) injury or damage to person or property caused by fire, or theft, or resulting from the operation of heating or
air conditioning or lighting apparatus, or from falling plaster, or from steam, gas, electricity, water, rain, snow, ice, or dampness, that may leak or flow from any part of the Property, or from the
pipes, appliances or plumbing work of the same.

17.2.Indemnification



10

---



17.3.Force Majeure.The obligations of Tenant
hereunder shall not be affected, impaired or excused, and Landlord shall have no liability whatsoever to Tenant, with respect to any act, event or circumstance arising out of (a) Landlord's
failure to fulfill, or delay in fulfilling any of its obligations under this Lease by reason of labor dispute, governmental preemption of property in connection with a public emergency or shortages of
fuel, supplies, or labor, or any other cause, whether similar or dissimilar, beyond Landlord's reasonable control; or (b) any failure or defect in the supply, quantity or character of utilities
furnished to the Premises, or by reason of any requirement, act or omission of any public utility or others serving the Property, beyond Landlord's reasonable control.

18. DAMAGE OR DESTRUCTION

18.1.Notification and Repair.Tenant shall give prompt
notice to Landlord and Agent of (a) any fire or other casualty to the Premises or the Property, and (b) any damage to or defect in any part or appurtenance of the Property's sanitary,
electrical, HVAC, elevator or other systems located in or passing through the Premises or any part thereof. Subject to the provisions of Section 18.3below, if the Property or the Premises is
damaged by fire or other insured casualty, Landlord shall repair (or cause Agent to
repair) the damage and restore and rebuild the Property and/or the Premises (except for Tenant's Property) with reasonable dispatch after (x) notice to it of the damage or destruction and

11

---

(y) the adjustment of the insurance proceeds attributable to such damage. Subject to the provisions ofSection 18.3below, Tenant shall
not be entitled to terminate this Lease and no damages, compensation or claim shall be payable by Landlord for purported inconvenience, loss of business or annoyance arising from any repair or
restoration of any portion of the Premises or of the Property pursuant to this Section. Landlord (or Agent, as the case may be) shall use its diligent, good faith efforts to make such repair or
restoration promptly and in such manner as not to unreasonably interfere with Tenant's use and occupancy of the Premises, but Landlord or Agent shall not be required to do such repair or restoration
work except during normal business hours of business days.

18.2.Rental Abatement.If (a) the Property is
damaged by fire or other casualty thereby causing the Premises to be inaccessible or (b) the Premises are partially damaged by fire or other casualty, the Rent shall be proportionally abated to
the extent of any actual loss of use of the Premises by Tenant.

18.3.Total Destruction.If the Property or the
Premises shall be totally destroyed by fire or other casualty, or if the Property shall be so damaged by fire or other casualty that (in the opinion of a reputable contractor or architect designated
by Landlord) (i) its repair or restoration requires more than one hundred eighty (180) days or (ii) such repair or restoration requires the expenditure of more than fifty percent
(50%) of the full insurable value of the Property immediately prior to the casualty or (iii) the damage (x) is less than the amount stated in (ii) above, but more than ten percent
(10%) of the full insurable value of the Property; and (y) occurs during the last two (2) years of the Initial Term or Renewal Term, Landlord and Tenant shall each have the option to
terminate this Lease (by so advising the other, in writing) within ten (10) days after said contractor or architect delivers written notice of its opinion to Landlord and Tenant, but in all
events prior to the commencement of any restoration of the Premises or the Property by Landlord. In such event, the termination shall be effective as of the date
upon which either Landlord or Tenant, as the case may be, receives timely written notice from the other terminating this Lease pursuant to the preceding sentence. If neither Landlord nor Tenant timely
delivers a termination notice, this Lease shall remain in full force and effect. If (A) any holder of a mortgage or deed of trust encumbering the Property or landlord pursuant to a ground lease
encumbering the Property (collectively, "Superior Parties") or other party entitled to the insurance proceeds fails to make such proceeds available to Landlord in an amount sufficient for restoration
of the Premises or the Property, or (B) the issuer of any casualty insurance policies on the Property fails to make available to Landlord sufficient proceeds for restoration of the Premises or
the Property, then Landlord may, at Landlord's sole option, terminate this Lease by giving Tenant written notice to such effect within thirty (30) days after Landlord receives notice from the
Superior Party or insurance company, as the case may be, that such proceeds shall not be made available, in which event the termination of this Lease shall be effective as of the date Tenant receives
written notice from Landlord of Landlord's election to terminate this Lease. For purposes of thisSection 18.3only, "full insurable value" shall
mean replacement cost, less the cost of footings, foundations and other structures below grade.

19. EMINENT DOMAIN

If the whole, or any substantial portion, of the Property is taken or condemned for any public use under any Law or by right of eminent domain, or by private
purchase in lieu thereof, and such taking would prevent or materially interfere with the Permitted Use of the Premises, this Lease shall terminate effective when the physical taking of said Premises
occurs. If less than a substantial portion of the Property is so taken or condemned, or if the taking or condemnation is temporary (regardless of the portion of the Property affected), this Lease
shall not terminate, but the Rent payable hereunder shall be proportionally abated to the extent of any actual loss of use of the Premises by Tenant. Landlord shall be entitled to any and all payment,
income, rent or award, or any interest therein whatsoever, which may be paid or made in connection with such a taking or conveyance, and Tenant shall have no claim against Landlord for the value of
any unexpired portion of this Lease. Notwithstanding the foregoing, any compensation specifically awarded to Tenant for loss of business or goodwill, or for its personal property, shall be the
property of Tenant.

20. SURRENDER AND HOLDOVER

On the last day of the Term, or upon any earlier termination of this Lease, or upon any re-entry by Landlord upon the Premises, (a) Tenant
shall quit and surrender the Premises to Landlord "broom-clean" and in good order, condition and repair, except for ordinary wear and tear and such damage or destruction as Landlord is required to
repair or restore under this Lease, and (b) Tenant shall remove all of Tenant's Property therefrom, except as otherwise expressly provided in this Lease. The obligations imposed under the
preceding sentence shall survive the termination or expiration of this Lease. If Tenant remains in possession after the Expiration Date hereof or after any earlier termination date of this Lease or of
Tenant's right to possession: (a) Tenant shall be deemed a tenant-at-will; (b) Tenant shall pay one hundred fifty percent (150%) of the aggregate of the Base
Rent and Additional Rent last prevailing hereunder, and also shall pay all damages sustained by Landlord, directly by reason of Tenant's remaining in possession after the expiration or termination of
this Lease; (c) there shall be no renewal or extension of this Lease by operation of law; and (d) the tenancy-at-will may be terminated upon thirty
(30) days' written notice from Landlord. The provisions of thisSection 20shall not constitute a waiver by Landlord of any
re-entry rights of Landlord provided hereunder or by law.

21. EVENTS OF DEFAULT

21.1.Default Provisions.Without limitation of the
other terms and provisions of this Lease, each of the following shall constitute a default by Tenant under this Lease: (a) if Tenant fails to pay Rent or any other payment when due hereunder;
or (b) if Tenant fails, whether by action or inaction, to timely comply with, or satisfy, any or all of the obligations imposed on Tenant under this Lease (other than the obligation to pay
Rent) for a period of thirty (30) days after Landlord's delivery to Tenant of written notice of such default under thisSubsection 21.1;
provided, however, that if the default cannot, by its nature, be cured within such thirty (30) day period, but Tenant commences and diligently pursues a cure of such default promptly within the
initial thirty (30) day cure period, then Landlord shall not exercise its remedies underSection 22unless such default remains uncured
for more than sixty (60) days after Landlord's notice.

21.2.Bankruptcy of Tenant.It shall be a default by
Tenant under this Lease if Tenant makes an assignment for the benefit of creditors, or files a voluntary petition under any state or federal bankruptcy or insolvency law, or an involuntary petition
alleging an act of bankruptcy or insolvency is filed against Tenant under any state or federal bankruptcy or insolvency law that is not dismissed within ninety (90) days, or whenever a petition
is filed by or against (to the extent not dismissed within ninety (90) days) Tenant under the reorganization provisions of the United States Bankruptcy Code or under the provisions of any law
or like import, or whenever a petition shall be filed by Tenant under the arrangement provisions of the United States Bankruptcy Code or similar law, or whenever a receiver of

13

---

Tenant, or of, or for, the property of Tenant shall be appointed, or Tenant admits it is insolvent or is not able to pay its debts as they mature.

22. RIGHTS AND REMEDIES

22.1.Landlord's Cure Rights Upon Default of Tenant.If
Tenant defaults in the performance of any of its obligations under this Lease, Landlord, without thereby waiving such default, may (but shall not be obligated to) perform the same for the account, and
at the expense of, Tenant upon compliance with any notice requirements and cure periods set forth inSection 21.2.

22.2.Landlord's Remedies.In the event of any default
by Tenant under this Lease, Landlord, at its option, and after the proper notice and cure period, but without additional notice or demand from Landlord, if any, as provided in Section 21.1has
expired, may, in addition to all other rights and remedies provided in this Lease, or otherwise at law or in equity:
(a) terminate this Lease and Tenant's right of possession of the Premises, and recover all damages to which Landlord is entitled under law, specifically including, without limitation,
accelerated Base Rent and Additional Rent attributable to the balance of the Term, and all Landlord's reasonable expenses of reletting the Premises (including repairs, alterations, improvements,
additions, decorations, legal fees and brokerage commissions), or (b) terminate Tenant's right of possession of the Premises without terminating this Lease; provided, however, that Landlord
shall use its reasonable efforts, whether Landlord elects to proceed under Subsections (a) or (b) above, to relet the Premises, or any part thereof for the account of Tenant, for such
rent and term and upon such terms and conditions as are acceptable to Landlord. If Landlord elects to pursue its rights and remedies under Subsection (b), then Landlord shall at any time have the
further right and remedy to rescind such election and pursue its rights and remedies under Subsection (a). For purposes of any reletting, Landlord is authorized to decorate, repair, alter and improve
the Premises to the extent deemed necessary by Landlord, in its sole, but reasonable, discretion. If the Premises are relet and a sufficient sum is not realized therefrom, to satisfy the payment, when
due, of Base Rent and Additional Rent reserved under the Lease for any monthly period (after payment of all Landlord's reasonable expenses of reletting), then Tenant shall, in Landlord's sole
judgment, either (i) pay any such deficiency monthly or (ii) pay such deficiency on an accelerated basis, which accelerated deficiency shall be discounted at a rate of six percent (6%)
per annum. If Landlord fails to relet the Premises, then Tenant shall pay to Landlord the sum of (x) the projected costs of Landlord's reasonable expenses of reletting (including the
anticipated costs of repairs, alterations, improvements, additions, legal fees and brokerage commissions) as reasonably estimated by Landlord and (y) the accelerated amount of Base Rent and
Additional Rent due under the Lease for the balance of the Term, discounted at a rate of six percent (6%) per annum. Tenant agrees that Landlord may file suit to recover any sums due to Landlord
hereunder from time to time and that such suit or recovery of any amount due Landlord hereunder shall not be any defense to any subsequent action brought for any amount not theretofore reduced to
judgment in favor of Landlord. In the event Landlord elects, pursuant to Subsection (b) of thisSection 22.2, to terminate Tenant's right
of possession only, without terminating this Lease, Landlord may, at Landlord's option, enter into the Premises, remove Tenant's Property, Tenant's signs and other evidences of tenancy, and take and
hold possession thereof, as provided inSection 20hereof; provided, however, that such entry and possession shall not terminate this Lease or
release Tenant, in whole or in part, from Tenant's obligation to pay the Base Rent and Additional Rent reserved hereunder for the full Term, or from any other obligation of Tenant under this Lease.
Any and all property that may be removed from the Premises by Landlord pursuant to the authority of the Lease or of law, to which Tenant is or may be entitled, may be handled, removed or stored by
Landlord at the risk, cost and expense of Tenant, and in no event or circumstance shall Landlord be responsible for the value, preservation or safekeeping thereof. Tenant shall pay to Landlord, upon
demand, any and all expenses incurred in such removal and all storage charges against such property so long as the same shall be in Landlord's possession or under Landlord's control. Any such property
of Tenant not retaken from storage by Tenant within thirty (30) days after the end of the

14

---

Term, however terminated, shall be conclusively presumed to have been conveyed by Tenant to Landlord under this Lease as in a bill of sale, without further payment or credit by Landlord to Tenant.

22.3.Additional Rights of Landlord.Any and all costs,
expenses and disbursements, of any kind or nature, incurred by Landlord or Agent in connection with the enforcement of any and all of the terms and provisions of this Lease, including reasonable
attorneys' fees (through all appellate proceedings), shall be due and payable (as Additional Rent) upon Landlord's submission of an invoice therefor. All sums advanced by Landlord or Agent on account
of Tenant under this Section, or pursuant to any other provision of this Lease, and all Base Rent and Additional Rent, if delinquent or not paid by Tenant and received by Landlord when due hereunder,
shall bear interest at the rate of five percent (5%) per annum above the "prime" or "reference" or "base" rate of interest publicly announced as such, from time to time, by The First National Bank of
Chicago, from the due date thereof until paid, and such interest shall be and constitute Additional Rent and be due and payable upon Landlord's or Agent's submission of an invoice therefor. The
various rights, remedies and elections of Landlord reserved, expressed or contained herein are cumulative and no one of them shall be deemed to be exclusive of the others or of such other rights,
remedies, options or elections as are now or may hereafter be conferred upon Landlord by law.

22.4.Event of Bankruptcy.In addition to, and in no
way limiting the other remedies set forth herein, Landlord and Tenant agree that if Tenant ever becomes the subject of a voluntary or involuntary bankruptcy, reorganization, composition, or other
similar type proceeding under the federal bankruptcy laws, as now enacted or hereinafter amended, then: (a) "adequate assurance of future performance" by Tenant and/or any assignee of Tenant
pursuant to Bankruptcy Code Section 365 will include (but not be limited to) payment of an additional/new security deposit in the amount of three (3) times the then-current
Base Rent payable hereunder; (b) any person or entity to which this Lease is assigned pursuant to the provisions of the Bankruptcy Code, shall be deemed, without further act or deed, to have
assumed all of the obligations of Tenant arising under this Lease on and after the effective date of such assignment. Any such assignee shall, upon demand by Landlord, execute and deliver to Landlord
an instrument confirming such assumption of liability; (c) notwithstanding anything in this Lease to the contrary, all amounts payable by Tenant to or on behalf of Landlord under this Lease,
whether or not expressly denominated as "Rent", shall constitute "rent" for the purposes of Section 502(b)(6) of the Bankruptcy Code; and (d) if this Lease is assigned to any person or
entity pursuant to the provisions of the Bankruptcy Code, any and all monies or other considerations payable or otherwise to be delivered to Landlord or Agent (including Base Rent, Additional Rent and
other amounts hereunder), shall be and remain the exclusive property of Landlord and shall not constitute property of Tenant or of the bankruptcy estate of Tenant. Any and all monies or other
considerations constituting Landlord's property under the preceding sentence not paid or delivered to Landlord or Agent shall be held in trust by Tenant or Tenant's bankruptcy estate for the benefit
of Landlord and shall be promptly paid to or turned over to Landlord.

23. BROKER

Tenant covenants, warrants and represents that the broker set forth inSection 1.10(A)was the only
broker to represent Tenant in the negotiation of this Lease ("Tenant's Broker"). Landlord covenants, warrants and represents that the broker set forth in Section 1.10(B)was the only broker to
represent Landlord in the negotiation of this Lease ("Landlord's Broker"). Landlord shall be solely
responsible for paying the commission of Landlord's Broker. Each party agrees to and hereby does defend, indemnify and hold the other harmless against and from any brokerage commissions or finder's
fees or claims therefor by a party claiming to have dealt with the indemnifying party and all costs, expenses and liabilities in connection therewith, including, without limitation, reasonable
attorneys' fees and expenses, for any breach of the foregoing. The foregoing indemnification shall survive the termination of this Lease for any reason.

24.3Non-Waiver.The failure of either
party to insist, in any one or more instances, upon the strict performance of any one or more of the obligations of this Lease, or to exercise any election herein contained, shall not be construed as

would sell the Property to a qualified third party. Tenant shall have thirty (30) days from the date of receipt of such notice to negotiate with Landlord a purchase in general conformity with
Landlord's terms. Landlord and Tenant agree to negotiate in good faith. After such thirty (30) day period (if Landlord and Tenant have not executed a Purchase Agreement), Landlord may market
the Property to third party prospective buyers without regard to any right(s) to purchase the Property by Tenant pursuant to this Lease. If Landlord enters into an agreement to sell the Property to a
third party, Tenant agrees to execute an Estoppel confirming (a) the status of the Lease and (b) Tenant's waiver of right(s) to purchase the Property.

## 

LEASE EXHIBIT B       CONSTRUCTION OF IMPROVEMENTS

This Exhibit B to the Lease sets forth the rights and obligations of Landlord and Tenant with respect to the construction of the Improvements (as
hereinafter defined).

1.Definitions:  For purposes of this Exhibit, the following terms shall have the following meanings,
and terms which are not defined below, but which are defined in the Lease shall have such meanings herein as are ascribed to such terms by the Lease:



2.Construction of Building Improvements:  The parties acknowledge that they currently contemplate that
Landlord shall cause the General Contractor to construct the Improvements in substantial accordance with the Preliminary Drawings; and that the final plans, specifications and working drawings for the
construction of the Building Improvements will be prepared on behalf of Landlord, based on the Preliminary Drawings (the "Final Plans and Specifications").



B-1

---



3.Construction of Tenant Improvements.The parties acknowledge that they currently contemplate that
Tenant shall cause the "Tenant's General Contractor" to construct the Tenant Improvements in substantial accordance with the plans, specifications, and working drawings for the construction of the
Tenant Improvements to be prepared on behalf of Tenant (the "Tenant Improvement Plans and Specifications").

B-2

---



B-3

---



4.Tenant's Extra Work.  If Tenant desires that any work be performed in connection with the
construction of the Improvements other than, or in addition to, the work described in the Preliminary Drawing (or the Final Plans and Specifications once completed and delivered to Tenant), as
approved by Landlord and Tenant [such other work is hereinafter called "Tenant's Extra Work"], the following provisions shall be applicable:



5.Rent Commencement Date:  Landlord and Tenant contemplate that the Building and the Premises will be
substantially complete on or about April 1, 2001 (the "Scheduled Commencement Date"). Tenant shall be liable to Landlord for the payment of Base Rent and any other payments under the Lease
beginning on the day (the "Commencement Date") after the date on which the Building Improvements and the Tenant Improvements are Substantially Completed; subject, however, to any postponement of the
Commencement Date occurring as a result of Tenant Delays. If the Building Improvements or Tenant Improvements are not Substantially Completed but are partially ready for occupancy, Tenant may, but
need not, occupy the portion of the Improvements that is ready for

B-4

---

occupancy, provided such partial occupancy is permitted by applicable law, and in the event of such partial occupancy, Tenant shall pay to Landlord pro rata Rent based upon the area of the Premises so
occupied by Tenant. Such obligation to pay Rent on a proportionate basis shall commence on the date on which Tenant first occupies and takes possession of any portion of the Premises, and shall
continue through the date on which all of the Improvements are Substantially Completed. Tenant's right to so occupy and utilize a portion of the Premises shall nevertheless be subject to Landlord's
reasonable approval, and throughout such partial occupancy, Tenant shall fully cooperate with Landlord to
facilitate Landlord's Substantial Completion of any remaining or outstanding Improvements without any interference. If Tenant occupies any portion of the Premises prior to Substantial Completion
thereof, the provisions of this Lease shall apply to such occupancy or use of the Premises by Tenant, except that the Term of this Lease shall not commence until the date that the entire Premises is
Substantially Completed.

6.Delays in Completion.



B-5

---



Tenant
hereby indemnifies, defends and holds Landlord harmless from and against any and all losses, damages, liabilities, claims, costs and expenses (including reasonable legal fees)
suffered or incurred by Landlord as a result of, or because of, any Tenant Delays.

Landlord
shall promptly notify Tenant of any events, conditions, circumstances, acts or omissions on the part of Tenant or its employees, agents, contractors or subcontractors that
have resulted in a Tenant Delay, which notice shall specify (i) the anticipated delay in the Commencement Date resulting from such Tenant Delay as of the date of such notice and
(ii) whether the conditions, events, acts, omissions or circumstances giving rise to such Tenant Delay persist as of the date of such notice.

7.Delivery of Possession, Punch List, and Acceptance Agreement.  As soon as the Building Improvements
are Substantially Completed, Landlord and Tenant shall together walk through the Premises and inspect all Improvements so completed, using reasonable efforts to discover all uncompleted or defective
construction in the Improvements. After such inspection has been completed, each party shall sign an acceptance agreement in the form attached hereto as Exhibit B-2(herein the "Acceptance
Agreement"),
which shall include by attachment a list of all "punch list" items which the parties agree are to be corrected by Landlord. As soon as such inspection has been completed and the Acceptance Agreement
executed, Landlord shall deliver possession of the Premises to Tenant. Landlord shall use reasonable efforts to complete and/or repair such "punch list" items within thirty (30) days after
executing the Acceptance Agreement. Landlord shall have no obligation to deliver possession of the Premises to Tenant until such procedures regarding the preparation of a punch list and the execution
of the Acceptance Agreement have been completed

8.Warranty.  Landlord shall, subject to the criteria and conditions set forth herein, provide its
warranty with respect to the Improvements in connection with any defective workmanship and materials discovered and brought to Landlord's attention pursuant to a proper Tenant's Defect Notice (as
hereinafter defined) delivered during a period of one (1) year from the date the Improvements are Substantially Completed (the "Warranty Period"). During the Warranty Period Landlord shall, at
Landlord's sole cost and expense, repair or replace any defective item occasioned by defective workmanship or materials in and with respect to the construction and installation of the Improvements
(and specifically excluding any installations by Tenant or any deficiencies in the Improvements created by, through or under Tenant or otherwise through no fault of or defective performance on the
part of Landlord), provided that (i) Tenant notifies Landlord, in writing and with reasonable specificity and detail, of the nature and extent of any such alleged defects in the Improvements
("Tenant's Defect Notice") and (ii) Tenant delivers Tenant's Defect Notice to Landlord prior to the expiration of the Warranty Period. In no event shall Landlord be liable to Tenant for damages
as a result of such defect, resulting from loss of business by Tenant or other consequential or speculative damages. Notwithstanding anything to the contrary contained herein, in no event shall
Landlord be liable for, and the warranty specified above shall not apply to, defects or alleged deficiencies in any materials or workmanship in or concerning the Improvements if and to the extent the
defect or deficiency is due to or caused by any Alterations performed by Tenant, installation of Tenant Improvements or the abuse, neglect, negligence or willful or intentional act or omission of
Tenant or its agents, subtenants, contractors, subcontractors, invitees, successors or assigns, including, without limitation, Tenant's failure to maintain a maintenance contract with respect to the
HVAC systems. From and after the expiration of the Warranty Period, (x) Landlord shall have no liability or obligation, of any nature whatsoever, to remedy, replace or correct any alleged
defects and deficiencies; and (y) Landlord shall reasonably cooperate with Tenant (but at no out-of-pocket expense to Landlord) in the enforcement, by Tenant, at
Tenant's sole cost and expense, of any express warranties or guarantees of workmanship or materials given by any subcontractors, architects, draftsmen, or materialmen engaged by Landlord to supply or
complete any of the Improvements, if and to the extent that such guarantees or warranties remain in effect after the expiration of the Warranty Period. In providing a Tenant Defect Notice, Tenant
shall be obligated to set forth with reasonable specificity and detail the nature and extent of such defect. Except as otherwise expressly set forth above in this Section from and after the earlier of
the date Tenant takes

B-6

---

partial occupancy or the Commencement Date, Tenant shall have and hold the Premises in an "as-is," "where-is" condition, without any liability or obligation on the part of
Landlord for making any alterations, improvements, repairs or replacements, of any kind, in or about the Premises at any time
during the Term of this Lease or any extension or renewal thereof, and Tenant shall maintain the Premises, and all parts thereof, in a good and sufficient state of repair as required under this Lease.
Notwithstanding Tenant's timely delivery of a Tenant's Defect Notice, at no time during the Term of this Lease, shall Tenant have any right, of any nature whatsoever, to withhold the timely payment of
any Rent due under the Lease, from time to time, as a result of, or due to, or because of, any alleged breaches by Landlord under this Lease or the alleged existence of any defects or deficiencies in
the Improvements. Notwithstanding anything contained herein to the contrary, none of the following items that may occur in the Improvements shall be considered defective items occasioned by defective
workmanship or materials required to be repaired by Landlord pursuant to this Section 7: (i) Any chips, scratches or marks on such items as tile, woodwork, mirrors, walls, porcelain,
glass (including breakage or cracks), plumbing fixtures, lighting fixtures, or doors not noted in the punch list set forth in the applicable Acceptance Agreement; (ii) Defects resulting from
ordinary wear and tear, misuse or neglect, or failure to provide proper maintenance; (iii) Cracking or scaling of the concrete flat work (which includes, but is not limited to, sidewalks and
warehouse floors) and cracks in foundation walls, if any, not resulting from infiltration of free water; (iv) Cracks in walks, driveways, parking lots, floor or fountains due to expanding and
contracting of concrete from change in temperature and compacting of the soil on which the concrete is placed; (v) The color of the concrete; (vi) Shrinkage in structural wood members;
and (vii) Drywall cracks, nail pops or seems due to drying out and normal expansion and contraction of the wood or masonry to which it has been secured.

9.Tenant's Access.  Landlord, in its sole discretion, may permit Tenant and Tenant's agents or
independent contractors to enter the Premises prior to the Commencement Date for the purpose of constructing the Tenant Improvements. Such entry shall be subject to the conditions that
(i) Tenant and Tenant's agents, contractors, workmen, mechanics, suppliers and invitees shall work in harmony and not interfere with Landlord and its agents and contractors in doing its work
in, to, or on the Premises; (ii) Tenant and/or Tenant's General Contractor shall maintain in full force and effect the insurance policy or policies required under the Lease; and shall cause the
Landlord to be designated an additional insured with respect to the Building Improvements; and (iii) Tenant shall pay for any utilities required solely by Tenant in connection with the Tenant's
early access to the Premises. Tenant agrees that any such entry into and access to the Premises shall be deemed to be under all of the terms, covenants, conditions and provisions of the Lease, except
as to the covenant to pay Rent. Tenant further agrees that to the extent permitted by law, Landlord and its principals shall not be liable in any way for any injury or death to any person or persons,
loss or damage to any of Tenant's work and installations made in the Premises or loss or damage to property placed therein prior to the Commencement Date, the same being at Tenant's sole risk, unless
such occurrence is due to Landlord's or Landlord's agents' gross negligence or willful misconduct. Tenant agrees to indemnify, defend and hold harmless Landlord from and against all actions, claims,
demands, costs, damages (including, without limitation incidental damages and consequential damages), penalties or expenses of any kind (including, without limitation, reasonable attorneys' fees),
which may be brought or made against Landlord, or which Landlord may pay or incur, by reason of the Tenant's early access to the Premises pursuant to this section or due to Tenant Improvements.

10.Authorized Representatives:  Tenant hereby appoints Mike Jaeb as its duly authorized representative
to review and approve the Preliminary Drawings and to review the Building Improvements Final Plans and Specifications, so as not to unreasonably delay completion of the Building Improvements, and
Landlord hereby appoints Gary Lally as its duly authorized representative to review and approve the Tenant Improvements Plans and Specifications. Landlord and Tenant hereby represent and warrant to
each other that their respective authorized representatives have authority to approve the Building Improvement Plans and Specifications and the Tenant Improvements Plans and Specifications.
