         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 one period of four (4) years and 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

         the annual Base Rent payable during the last full month of the first
         Renewal Term increased at a rate of two and one-half percent (2.5 %)
         per annum compounded annually over the entire second Renewal Term.

         The annual Base Rent for the Premises during the third Renewal Term, if

         the annual Base Rent payable during the last full month of the second
         Renewal Term increased at a rate of two and one-half percent (2.5%) per
         annum compounded annually over the entire third Renewal Term.

         2.3.     TYPES OF RENTAL PAYMENTS. Commencing on the Rent Commencement
Date, Tenant shall pay rents of (a) annual base rent (as set forth in SECTION
1.12 hereof), 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 under SECTION 10.1 hereof
(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 in SECTION 1.6 above
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, 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 in SECTION 1.8 above and for no other purpose whatsoever. Tenant shall
not, at any time, use or occupy, or suffer or permit anyone to use or occupy,
the Premises, or do or permit anything to be done in the Premises, in any manner
that may (a) violate any Certificate of Occupancy for the Premises or the
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


                                       2
<PAGE>


Premises; or (e) unreasonably annoy, inconvenience or disrupt the operations or
tenancies of other tenants or users of the Property or, if any or other users or
occupants of the park within which the Property is located, if applicable.

         4.2.     SIGNAGE. Tenant shall not affix any sign of any 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, codes, ordinances, restrictions rules and
regulations applicable thereto. Tenant shall remove all signs of Tenant upon the
expiration or earlier termination of this Lease and immediately repair any
damage to the Property caused by, or resulting from, such removal.

         4.3.     SECURITY DEPOSIT. Tenant has on August 1, 2000 deposited with
Landlord the sum set forth in SECTION 1.11 above, 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.

If Tenant fails to take possession of the Premises on the Commencement Date,
Landlord may retain the Security and exercise any legal or equitable remedies.

5.       CONDITION AND DELIVERY OF PREMISES

         5.1.     CONDITION OF PREMISES. Landlord shall deliver the Premises to
Tenant in a condition substantially consistent with the Final Plans and
Specifications, as may be revised or amended by change orders or Tenant's Extra
Work, subject to the "punch list" items (all as hereinafter defined and further
described in EXHIBIT "B" hereto). Except as otherwise expressly provided in
EXHIBIT "B", Landlord shall not be obligated to make any repairs, replacements
or improvements (whether structural or otherwise) of any kind or nature to the
Premises in connection with, or in consideration of, this Lease.

         5.2.     DELAY IN COMMENCEMENT. Except as otherwise expressly provided
in EXHIBIT "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 in EXHIBIT "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 in EXHIBIT "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. Specifically, Tenant agrees that 1) this Lease is subordinate to a
Mortgage granted in favor of General Electric Capital Business Asset Funding
Corporation ("GE Capital"); 2) it attorns to GE Capital with such attornment
effective upon GE Capital's acquisition to the Property; 3) to execute such
further evidence of attornment as GE Capital may request from time to time; and
4) attornment of the Tenant shall not be terminated by foreclosure.
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.


                                       3
<PAGE>


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 in SECTION 4 above; 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
under Section 2.3 of 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 this SECTION 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. Sections 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 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,


                                       4
<PAGE>


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. This SECTION 9.2 does 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 this SECTION
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.

10.      INSURANCE

         10.1.    LANDLORD INSURANCE. Landlord shall maintain (a) "all-risk"
property insurance covering the Premises (at its full replacement cost), but
excluding Tenant's Property, and (b) commercial general public liability
insurance covering Landlord for claims arising out of liability for bodily
injury, death, personal injury, advertising injury and property damage occurring
in and about the Property and otherwise resulting from any acts and operations
of Landlord, its agents and employees, and (c) rent loss insurance
(collectively, "Landlord's Policies"), all of the above with limits that are
required by any lender(s) of Landlord, or as are otherwise reasonably determined
by Landlord.

         10.2.    TENANT INSURANCE. Tenant shall purchase at its own expense and
keep in force during this Lease a policy or policies of (i) "All-risk" property

personal injury and property damage, in the amount of not less than Two Million
Dollars ($2,000,000.00) per occurrence and Five Million Dollars ($5,000,000.00)
annual general aggregate per location, and comprehensive automobile liability
insurance covering Tenant against any losses arising out of liability for
personal injuries or deaths of persons and property damage occurring in or about
the Premises and Property; and (iii) Business Interruption Coverage. Said
policies shall (a) name Landlord and any party holding an interest to which this
Lease may be subordinated as additional insureds; (b) be issued by an insurance
company with a Best rating of A-X or better and otherwise reasonably acceptable
to Landlord and licensed to do business in the state in which the Property is
located; (c) provide that said insurance shall not be canceled or materially
modified unless thirty (30) days' prior written notice shall have been given to
Landlord, (d) provide coverage on an occurrence basis; (e) contain a
severability of insured parties provision and a cross liability endorsement; (f)

commencement of the Lease and renewals thereof shall be delivered at least
thirty (30) days prior to the expiration of said insurance.

         10.3.    WAIVER OF SUBROGATION. To the extent permitted by law, and
without affecting the coverage provided by insurance required to be maintained
hereunder, Landlord and Tenant each waive any right to recover against the other
(a) damages for injury to or death of persons, (b) damages to property, (c)
damages to the Premises or any part thereof or (d) claims arising by reason of
the foregoing, to the extent such damages and claims are insured against or
required to be insured against by Landlord or Tenant under this Lease. This
provision is intended to waive, fully and for the benefit of each party, any
rights and/or claims which might give rise to a right of subrogation by any
insurance carrier. The coverage obtained by each party pursuant to


                                       5
<PAGE>


this Lease shall include, without limitation, a waiver of subrogation by the
carrier which conforms to the provisions of this section.

11.      ALTERATIONS

         11.1.    PROCEDURAL REQUIREMENTS. Tenant may, from time to time, at its
expense, make alterations or improvements in and to the Premises (hereinafter
collectively referred to as "Alterations"), provided that Tenant first obtains
the written consent of Landlord in each instance. Landlord's consent to
Alterations shall not be unreasonably withheld, provided that: (a) the
Alterations are non-structural and the structural integrity of the Property

Additionally, before proceeding with any Alterations, Tenant shall (i) at
Tenant's expense, obtain all necessary governmental permits and certificates for
the commencement and prosecution of Alterations; (ii) submit to Agent, for
Landlord's written approval, working drawings, plans and specifications and all

insurance. Such insurance policies shall satisfy the obligations imposed under
SECTION 10.2. After obtaining Landlord's approval to the Alterations, Tenant

diligently performed in a good and workmanlike manner, using new materials and
equipment at least equal in quality and class to the standards for the Property
established by Landlord or Agent. Tenant shall obtain all necessary permits and
certificates for final governmental approval of the Alterations and shall
provide Landlord with "as built" plans, copies of all construction contracts,
governmental permits and certificates and proof of payment for all labor and
materials, including, without limitation, copies of paid invoices and final lien
waivers.

         11.3.    LIEN PROHIBITION. Tenant shall pay when due all 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 Tenant's leasehold estate. Tenant, at its expense,
shall procure the satisfaction or discharge of record of all such liens and
encumbrances within thirty (30) days after the filing, or Tenant 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 in SECTION 22.3 below, 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.

12.      LANDLORD'S AND TENANT'S PROPERTY

         12.1.    LANDLORD'S PROPERTY. Subject to SECTION 12.2 below, the
Building Improvements and all fixtures, machinery, equipment, improvements and
appurtenances attached to, or built into, the Premises at the commencement of,
or during the Term, whether or not placed there by or at the expense of Tenant,
shall become and remain a part of the Premises; shall be deemed the property of
Landlord (the "Landlord's Property"), without compensation or credit to Tenant;
and shall not be removed by Tenant at the Expiration Date unless Landlord
requests their removal. Further, any personal property in the Premises on the
Commencement Date, movable or otherwise, unless installed and paid for by
Tenant, shall be and shall remain the property of Landlord and shall not be
removed by Tenant. In no event shall Tenant remove any of the following
materials or equipment without Landlord's prior written consent: any power
wiring or power panels, lighting or lighting fixtures, wall or window coverings,
carpets or other floor coverings, heaters, air conditioners or any other HVAC
equipment, fencing or security gates, or other similar building operating
equipment and decorations.

         12.2.    TENANT'S PROPERTY. All movable non-structural partitions,
business and trade fixtures, machinery and equipment, communications equipment
and office equipment, that are installed in the Premises by, or for the account
of, Tenant and that can be removed without structural damage to the Property,
and all furniture, furnishings and other articles of movable personal property
owned by Tenant and located in the Premises (collectively, the "Tenant's
Property") shall be and shall remain


                                       6
<PAGE>


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 termination date, may, at the option of
Landlord, be deemed to have been abandoned, and in such case, such items may be
retained by Landlord as its property or be disposed of by Landlord, in
Landlord's sole and absolute discretion and without accountability, at Tenant's
expense. Notwithstanding the foregoing, if Tenant is in default under the terms
of this Lease, it may remove Tenant's Property from the Premises only upon the
express written direction of Landlord.

13.      REPAIRS AND MAINTENANCE

Tenant shall, at its expense, throughout the Term, maintain and preserve, in
first class condition, (subject to normal and customary wear and tear), the
Premises and the fixtures and appurtenances therein. Except as otherwise
specifically provided in EXHIBIT "B" hereto, Tenant shall also be responsible
for all structural and non-structural repairs and replacements, interior and
exterior, ordinary and extraordinary, in and to the Premises and the facilities
and systems thereof (but not limited to, the roof, the Premises, sidewalks,
driveways, curbs, loading areas, landscaped areas and parking lot, and the
electrical, mechanical, HVAC, and plumbing systems). Tenant shall enter into a
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 relating to the load
bearing capacity of the Improvements as set forth in the Final Plans and
Specifications or as otherwise directed by Landlord.

14.      UTILITIES

Tenant shall purchase all utility services from the utility or municipality
providing such service; shall provide for scavenger, cleaning and extermination
services; and shall pay for such services when payments are due. Tenant shall be
solely responsible for the repair and maintenance of any meters necessary in
connection with such services. Tenant's use of electrical energy in the Premises
shall not, at any time, exceed the capacity of either or both of (i) any of the
electrical conductors and equipment in or otherwise servicing the Premises; and
(ii) the Property's HVAC systems.

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.

16.      LANDLORD'S RIGHTS

Landlord, Agent and their respective agents, employees and representatives shall
have the right to enter and/or pass through the Premises at any time or times
upon reasonable prior notice (except in the event of emergency) (a) to examine
and inspect the Premises and to show them to actual and prospective lenders,
prospective purchasers or mortgagees 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 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


                                       7
<PAGE>


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, Landlord,
or its respective members, partners, directors, officers, agents and employees
shall not be liable (a) for any damage caused by other tenants or persons in,
upon or about the Property, or caused by operations in construction of any
public or quasi-public work; (b) with respect to matters for which Landlord is
liable, for consequential or indirect damages purportedly arising out of any
loss of use of the Premises or any equipment or facilities therein by Tenant or
any person claiming through or 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

                  17.2.1.  TENANT INDEMNIFICATION. Tenant hereby indemnifies,
         defends, and holds Landlord and its affiliates, members, owners,
         partners, directors, officers, agents and employees (collectively,
         "Landlord Indemnified Parties") harmless from and against any and all
         Losses (defined below) arising from or in connection with (a) the
         conduct or management of either or both the Property and the Premises
         or any business therein, or any work, Tenant Improvements, or
         Alterations done, or any condition created (other than by Landlord) in
         or about the Premises during the Term or during the period of time, if
         any, prior to the Commencement Date that Tenant may have been given
         access to the Premises; (b) any act, omission or negligence of Tenant
         or Tenant's Parties; (c) any accident, injury or damage whatsoever
         (unless caused by Landlord's gross negligence or willful misconduct)
         occurring in, at or upon either or both the Property and the Premises;
         (d) any breach by Tenant of any of its warranties, representations or
         covenants under this Lease; (e) any actions necessary to protect
         Landlord's interest under this Lease in a bankruptcy proceeding or
         other proceeding under the Bankruptcy Code; (f) any violation or
         alleged violation by Tenant of any Laws, including, without limitation,
         any Environmental Law; (g) any breach of the provisions of Article 9 by
         Tenant or any of Tenant's Parties; (h) any generation, transport,
         storage, use, treatment, disposal or presence on, about or from the
         Premises or the Property of any Hazardous Materials; (i) claims for
         work or labor performed or materials supplies furnished to or at the
         request of Tenant; and (j) claims arising from any breach or default on
         the part of Tenant in the performance of any covenant contained in this
         Lease (collectively, "Tenant's Indemnified Matters"). In case any
         action or proceeding is brought against any or all of Landlord and the
         Landlord Indemnified Parties by reason of any of Tenant's Indemnified
         Matters, Tenant, upon notice from any or all of Landlord, Agent or any
         Superior Party (defined below), shall resist and defend such action or
         proceeding by counsel reasonably satisfactory to Landlord. The term
         "Losses" shall mean all claims, demands, expenses, actions, judgments,
         damages (whether direct or indirect, known or unknown, foreseen or
         unforeseen), penalties, fines, liabilities, losses of every kind and
         nature (including, without limitation, property damage, diminution in
         value of Landlord's interest in the Premises or the Property, damages
         for the loss or restriction on use of any space or amenity within the
         Premises or the Property, damages arising from any adverse impact on
         marketing space in the Property, sums paid in settlement of claims and
         any costs and expenses associated with injury, illness or death to or
         of any person), suits, administrative proceedings, costs and fees,
         including, without limitation, attorneys' and consultants' fees and
         expenses, and the costs of cleanup, remediation, removal and
         restoration, that are in any way related to any matter covered by the
         foregoing indemnity. The provisions of this SECTION 17.2.1 shall
         survive the expiration or termination of this Lease.

                  17.2.2.  LANDLORD INDEMNIFICATION. Landlord hereby
         indemnifies, defends and holds Tenant harmless from and against any and
         all claims, losses, costs, damages (actual, but not consequential or
         speculative), judgments, causes of action, administrative proceedings
         and third party expenses (including, but not limited to, court costs
         and reasonable attorneys' fees) actually suffered or incurred by Tenant
         as the sole and direct result of any negligent, willful or intentional
         acts or omissions of any or all of Landlord, Agent and any parties
         within the direct and sole control of either of Landlord or Agent. In
         the event that any action or proceeding is brought against Tenant, and
         the foregoing indemnity is applicable to such action or proceeding,
         then Landlord, upon notice from Tenant, shall resist and defend such
         action or proceeding by counsel reasonably satisfactory to Tenant.
         Notwithstanding anything to the contrary set forth in this Lease,
         however, in all events and under all circumstances, the liability of
         Landlord to Tenant shall be


                                       8
<PAGE>


         limited to the interest of Landlord in the Property, and Tenant agrees
         to look solely to Landlord's interest in the Property for the recovery
         of any judgment or award against Landlord, it being intended that
         Landlord shall not be personally liable for any judgment or deficiency.
         The provisions of this SECTION 17.2.2 shall survive the expiration or
         termination of this Lease.

         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 18.3 below, 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 (y) the adjustment of the insurance proceeds attributable to
such damage. Subject to the provisions of SECTION 18.3 below, 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 this SECTION 18.3 only, "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


                                       9
<PAGE>


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 this SECTION 20 shall 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 this SUBSECTION 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 under
SECTION 22 unless 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 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 in SECTION
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 21.1 has 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


                                       10
<PAGE>

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 eight percent (8%) 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 eight
percent (8%) 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 this
SECTION 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 in SECTION 20 hereof;
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 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 in SECTION
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


                                       11

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.      MISCELLANEOUS

         24.1.    MERGER. All prior understandings and agreements between the
parties are merged in this Lease, which alone fully and completely expresses the
agreement of the parties. No agreement shall be effective to modify this Lease,
in whole or in part, unless such agreement is in writing, and is signed by the
party against whom enforcement of said change or modification is sought.

         24.2.    NOTICES. Any notice required to be given by either party
pursuant to this Lease, shall be in writing and shall be deemed to have been
properly given, rendered or made only if personally delivered, or if sent by
Federal Express or other comparable commercial overnight delivery service,
addressed to the other party at the addresses set forth below (or to such other
address as Landlord or Tenant may designate to each other from time to time by

         24.3     NON-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 a waiver or relinquishment for the future of the performance
of such one or more obligations of this Lease or of the right to exercise such
election, but the Lease shall continue and remain in full force and effect with
respect to any subsequent breach, act or omission. The receipt and acceptance by
Landlord or Agent of Base Rent or Additional Rent with knowledge of breach by
Tenant of any obligation of this Lease shall not be deemed a waiver of such
breach.

         24.4     LEGAL COSTS. Any party in breach or default under this Lease
(the "Defaulting Party") shall reimburse the other party (the "Nondefaulting
Party") upon demand for any legal fees and court (or other administrative
proceeding) costs or expenses that the Nondefaulting Party incurs in connection
with the breach or default, regardless whether suit is commenced or judgment
entered. Such costs shall include legal fees and costs incurred for the
negotiation of a settlement, enforcement of rights or otherwise. Furthermore, in
the event of litigation, the court in such action shall award to the party in
whose favor a judgment is entered a reasonable sum as attorneys' fees and costs,
which sum shall be paid by the losing party. Tenant shall pay Landlord's
attorneys' reasonable fees incurred in connection with Tenant's request for
Landlord's consent under provisions of this Lease governing assignment and
subletting, or in connection with any other act which Tenant proposes to do and
which requires Landlord's consent.

         24.5     PARTIES BOUND. Except as otherwise expressly provided for in
this Lease, this Lease shall be binding upon and inure the benefit of, the
successors and assignees of the parties hereto. Tenant hereby releases Landlord
named herein from any obligations of Landlord for any period subsequent to the
conveyance and transfer of Landlord's ownership interest in the Property. In the
event of such conveyance and transfer, Landlord's obligations shall thereafter
be binding upon each transferee (whether Successor Landlord or otherwise). No
obligation of Landlord shall arise under this Lease until the instrument is
signed by, and delivered to, both Landlord and Tenant.

         24.6     RECORDATION OF LEASE. Tenant shall not record or file this
Lease (or any memorandum hereof) in the public records of any county or state.

         24.7     SURVIVAL OF OBLIGATIONS. Upon the expiration or other
termination of this Lease, neither party shall have any further obligation or
liability to the other except as otherwise expressly provided in this Lease and
except for such obligations as, by their nature or under the circumstances, can
only be, or by the provisions of this Lease, may be performed after such
expiration or other termination.

         24.8     GOVERNING LAW; CONSTRUCTION. This Lease shall be governed by
and construed in accordance with the laws of the state in which the Property is
located. If any provision of this Lease shall be invalid or unenforceable, the
remainder of this Lease shall not be affected but shall be enforced to the
extent permitted by law. The captions, headings and titles in this Lease are
solely for convenience of reference and shall not affect its interpretation.
This Lease shall be construed without regard to any presumption or other rule
requiring construction against the party causing this Lease to be drafted. Each
covenant, agreement, obligation, or other provision of this Lease to be
performed by Tenant, shall be construed as a separate and independent covenant
of Tenant, not dependent on any other provision of this Lease. All terms and
words used in this Lease, regardless of the number or gender in which they are
used, shall be deemed to include any other number and any other gender as the
context may require. This Lease may be executed in counterpart and, when all
counterpart documents are executed, the counterparts shall constitute a single
binding instrument.

         24.9     TIME. Time is of the essence of this Lease. If the time for
performance hereunder falls on a Saturday, Sunday or a day that is recognized as
a holiday in the state in which the Property is located, then such time shall be
deemed extended to the next day that is not a Saturday, Sunday or holiday in
said state.

         24.10    AUTHORITY OF TENANT. If Tenant is a corporation, partnership,
association or any other entity, it shall deliver to Landlord, concurrently with
the delivery to Landlord of an executed Lease, certified resolutions of Tenant's
directors or other governing person or body (i) authorizing execution and
delivery of this Lease and the performance by Tenant of its obligationshereunder
and (ii) certifying the authority of the party executing the Lease as having
been duly authorized to do so.

         24.11    WAIVER OF TRIAL BY JURY. THE LANDLORD AND THE TENANT, TO THE
FULLEST EXTENT THAT THEY MAY LAWFULLY DO SO, HEREBY WAIVE TRIAL BY JURY IN ANY
ACTION OR PROCEEDING BROUGHT BY ANY PARTY TO THIS LEASE WITH RESPECT TO THIS
LEASE, THE PREMISES, OR ANY OTHER MATTER RELATED TO THIS LEASE OR THE PREMISES.

         24.12    SUBMISSION OF LEASE. Submission of this Lease to Tenant for
signature does not constitute a reservation of space or an option to lease. This
Lease is not effective until execution by and delivery to both Landlord and
Tenant.

         24.13    RIGHT OF FIRST OPPORTUNITY TO PURCHASE. If at any time during
the Lease Term the Landlord decides to market the Property for sale, Landlord
shall advise Tenant in writing of its intent to market the Property, and
indicate terms upon which Landlord 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. Tenant's
rights hereunder shall not survive past the initial sale of the Property to a
third party. Future owners of the Property shall have no obligation to offer
Tenant any such opportunity to purchase the Property.

         24.14    RIDERS. All Riders and Exhibits attached hereto and executed
(or initialed both by Landlord and Tenant) shall be deemed to be a part hereof
and hereby incorporated herein.

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

           Lot 5, Block 1, Chanhassan Lakes Business Park 7th Addition

                                 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:

                  (a)      PRELIMINARY DRAWINGS: The term "Preliminary Drawings"
         shall mean the outline specifications and preliminary drawings prepared
         on behalf of Landlord and approved by Tenant for the Improvements to be
         constructed by Landlord which are described in attached EXHIBIT B-1.

                  (b)      IMPROVEMENTS: The term "Building Improvements" shall
         mean a 2 story building (the "Building") located on the Property
         containing approximately 103,825 square feet, together with all
         building shell improvements and all related nonstructural improvements
         and utilities to be located on the Property, to be as more particularly
         shown and described in the Building Improvements Final Plans and
         Specifications (defined below) to be prepared by Landlord as
         hereinafter provided. Building Improvements shall not include the
         "Tenant Improvements" referred to in Section 1(d) below.

                  (c)      SUBSTANTIAL COMPLETION AND SUBSTANTIALLY COMPLETE.
         The terms "Substantial Completion" and "Substantially Complete" shall
         each mean the earlier of: (i) the date when the construction of the
         Building Improvements and the Tenant Improvements have been
         substantially completed in accordance with the requirements of the
         Final Plans and Specifications and the Tenant Improvement Plans and
         Specifications, respectively, excepting only "punch list items", or
         (ii) the date Tenant begins conducting business or commences operations
         within the Building, or (iii) the issuance of a temporary or permanent
         certificate of occupancy by the City of Chanhassen.

                  (d)      TENANT IMPROVEMENTS. "Tenant Improvements" shall mean
         the alterations, additions or improvements to be made or constructed to
         the interior of the Building in excess of Building Improvements.

         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").

                  (a)      DEVELOPMENT AND APPROVAL OF BUILDING FINAL PLANS AND
         SPECIFICATIONS: As soon hereafter as is reasonably practical, Landlord
         shall cause the Building Final Plans and Specifications to be prepared
         and delivered to Tenant for its review and approval (which approval
         shall not be unreasonably withheld). For purposes of this Lease,
         Tenant's review and approval of the Building Final Plans and
         Specifications shall be limited solely to those items that do not
         materially conform to the Preliminary Drawings. Tenant, acting
         reasonably and in good faith, shall have five (5) business days from
         Landlord's delivery of the Building Final Plans and Specifications to
         advise Landlord, in writing, as to whether or not Tenant desires any
         changes to the Building Final Plans and Specifications because of a
         material deviation from the Preliminary Drawings. If Tenant fails to
         timely respond, Tenant shall automatically be deemed to have approved
         the Building Final Plans and Specifications. If Tenant timely requests
         a change to the Building Final Plans and Specifications ("Tenant's
         Objection"), Tenant shall also, within such 5 business day period,
         advise Landlord, with reasonable specificity and detail, of Tenant's
         Objection, and provided Landlord determines and agrees that such
         requested change is necessary due to a material deviation in the
         Building Final Plans and Specifications from the Preliminary Drawings,
         Landlord shall then use its reasonable efforts to incorporate such
         change in the Building Final Plans and Specifications as soon as
         reasonably practicable after delivery of Tenant's Objection. Upon
         approval or deemed approval of the Building Final Plans and
         Specifications, those Building Final Plans and Specifications shall
         replace and be utilized and relied on in lieu of the Preliminary
         Drawings. (The date on which Landlord and Tenant mutually agree upon
         the Building Final Plans and Specifications, or the date on which
         Tenant is deemed to have approved them, whichever is applicable, shall
         be referred to as the "Building Improvements Plan Approval Date").

                  (b)      BUILDING IMPROVEMENTS CONSTRUCTION CONTRACT. The
         parties acknowledge that Landlord proposes to enter into a contract for
         construction (the "Building Improvements Construction Contract") of the
         Building Improvements with a general contractor (the "General
         Contractor") to be selected by Landlord, subject to Tenant's consent,
         which consent shall not be unreasonably withheld. Landlord may elect to
         replace, in its reasonable discretion and for good cause, the General
         Contractor at any time.


                                      B-1
<PAGE>


                  (c)      COMMENCEMENT AND COMPLETION OF CONSTRUCTION OF THE
         BUILDING IMPROVEMENTS. Landlord shall, at Landlord's sole cost and
         expense (except as otherwise provided herein), furnish all of the
         design, material, labor and equipment required to construct the
         Improvements on the Property, pursuant to and as described by the
         Preliminary Drawings, as revised by the Final Plans and Specifications.
         The Building Improvements shall be constructed in a good and
         workmanlike manner, substantially in accordance with the Building Final
         Plans and Specification and completed substantially in accordance with
         all applicable statutes, ordinances and building codes, governmental
         rules, regulations and orders relating to construction of the
         Improvements (but not relating to Tenant's use or occupancy). Landlord
         shall diligently proceed with the construction of the Building
         Improvements. If Landlord fails to substantially complete the Building
         Improvements and deliver possession of the Premises to Tenant on or
         before the Tenant's Possession Date and such failure is caused or
         contributed to by Tenant Delays (as hereinafter defined), or delays
         caused by Tenant or those acting for or under Tenant, or Force Majeure
         Delays (as hereinafter defined) (collectively, "Excused Delays") then
         the Tenant's Possession Date shall be extended for any and all delays
         in the Substantial Completion of the Building Improvements caused by or
         attributable to such Excused Delay(s).

                  (d)      CHANGES TO FINAL PLANS AND SPECIFICATIONS. After the
         Building Improvements Plan Approval Date, Tenant shall not have the
         right to order extra work or change orders with respect to the
         construction of the Improvements without the prior written consent of
         Landlord. Extra work or change orders requested by either Landlord or
         Tenant shall be made in writing, shall specify in detail any added or
         reduced cost and/or estimate of construction delay resulting therefrom,
         and shall become effective and a part of the Building Final Plans and
         Specifications once approved in writing by both parties. If a change
         order approved or requested by Tenant results in an increase in the
         cost of constructing the Improvements, Tenant shall pay the amount of
         such increase caused by the change order approved or requested by
         Tenant as provided in Section 3 below.

                  (e)      INCREASES IN COST OF CONSTRUCTION. In the event that
         due to any Excused Delays or any requested change in the scope or
         design of the Project by Tenant, Landlord will incur additional or
         increased costs in connection with construction of the Improvements,
         then Tenant shall be solely responsible for such costs, which Tenant
         shall pay promptly upon receipt of invoices from Landlord, and in any
         event within fifteen (15) days after receipt of such invoices.
         Provided, however, that any increased costs attributable to winter
         conditions shall not exceed $175,000.

         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").

                  (a)      DEVELOPMENT AND APPROVAL OF THE TENANT IMPROVEMENTS
                  PLANS AND SPECIFICATIONS. As soon hereafter as reasonably
                  practical, Tenant shall cause the Tenant Improvement Plans and
                  Specifications to be prepared and delivered to Landlord for
                  its review and approval (which approval shall not be
                  unreasonably withheld). Landlord, acting reasonably and in
                  good faith, shall have five (5) business days from Tenant's
                  delivery of the Tenant Improvement Plans and Specifications to
                  advise Tenant, in writing, as to whether Landlord desires any
                  changes to the Tenant Improvement Plans and Specifications. If
                  Landlord timely requests a change to the Tenant Improvement
                  Plans and Specifications ("Landlord's Objection"), Landlord
                  shall also, within such five (5) business day period, advise
                  Tenant, with reasonable specificity and detail, of Landlord's
                  Objection, and provided Tenant determines and agrees that such
                  requested change is reasonable and in accord with Tenant's
                  space plan and desired design criteria, Tenant shall then use
                  its reasonable efforts to incorporate such change into the
                  Tenant Improvement Plans and Specifications as soon as
                  reasonably practical after delivery of Landlord's Objection.
                  Upon approval or deemed approval of the Tenant Improvement
                  Plans and Specifications, the Tenant Improvement Plans and
                  Specifications shall be considered final and complete unless
                  subsequently changed as provided herein. The date on which
                  Landlord and Tenant mutually agree on the Tenant Improvement
                  Plans and Specifications, or the date on which Tenant is
                  deemed to have approved them, whichever is applicable, shall
                  be referred to as the "Tenant Improvement Plans Approval
                  Date").

                  (b)      TENANT IMPROVEMENTS CONSTRUCTION CONTRACT. The
                  parties acknowledge that Tenant proposes to enter into a
                  contract for construction (the "Tenant Improvements
                  Construction Contract") of the Tenant Improvements with a
                  general contractor (the "Tenant's General Contractor")
                  selected by it, subject to Landlord's consent, which consent
                  shall not be unreasonably withheld.

                  (c)      COMMENCEMENT AND COMPLETION OF CONSTRUCTION OF THE
                  TENANT IMPROVEMENTS. Tenant shall, at Tenant's sole cost and
                  expense (except as otherwise provided herein), furnish all of
                  the design, material, labor and equipment required to
                  construct to Tenant Improvements on the Premises, pursuant to
                  and as described by the Tenant Improvements Plans and
                  Specifications. The Tenant Improvements shall be


                                      B-2
<PAGE>


                  constructed in a good and workmanlike manner, substantially in
                  accordance with the Tenant Improvements Plans and
                  Specifications and completed substantially in accordance with
                  all applicable statutes, ordinances, and building codes,
                  governmental rules, regulations and orders relating to
                  construction of the Tenant Improvements. Provided that
                  Landlord diligently proceeds with construction of the Building
                  Improvements, Tenant shall, at such time as the building shell
                  is complete, diligently proceed with construction of the
                  Tenant Improvements.

                  (d)      CHANGES TO TENANT IMPROVEMENT PLANS AND
                  SPECIFICATIONS. After the Tenant Improvements Plans Approval
                  Date, Tenant shall not have the right to order extra work or
                  change orders with respect to the construction of the Tenant
                  Improvements which would affect the structural integrity of
                  the Building or the efficiency or operation of the Building's
                  heating, ventilating, plumbing or electrical equipment or
                  systems without the prior written consent of Landlord. Extra
                  work or change orders requested by either Landlord or Tenant
                  shall be made in writing, shall specify in detail any added or
                  reduced cost and/or estimate of construction delay resulting
                  therefrom, and shall become effective and a part of the Tenant
                  Improvements Plans and Specifications once approved in writing
                  by both parties.

                  (e)      LANDLORD'S CONTRIBUTION. Upon completion of the
                  Tenant Improvements and Tenant's satisfaction of all
                  requirements as set forth herein, Landlord shall make a dollar
                  contribution of Two million five hundred thousand ($3,350,000)
                  Dollars ("Landlord's Contribution") for application to the
                  cost of the Tenant Improvements. If the cost of the Tenant
                  Improvements exceeds the Landlord's Contribution, Tenant shall
                  have the sole responsibility for the payment of such excess
                  cost. If the cost of the Tenant Improvements is less than
                  Landlord's Contribution, Tenant may elect (a) to receive a
                  refund from Landlord in an amount equal to the difference
                  between the cost of the Tenant Improvements and $3,350,000, or
                  (b) receive a credit toward installments of Rent as they
                  become due under the Lease. At Tenant's option, Tenant may
                  request that portions of Landlord's Contribution be paid out
                  in installments utilizing prudent construction draw
                  disbursement procedures reasonably required by Landlord;
                  provided, however, that it is understood and agreed that (i)
                  if Landlord elects to make such disbursements through a title
                  insurance company, Tenant will pay all fees and costs of the
                  title insurance company; and (ii) Tenant shall not make more
                  than one draw request in any calendar month.

         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:

                  (a)      Tenant shall, at its sole cost and expense, furnish
         to Landlord, Landlord's architect, Landlord's General Contractor, and
         any electrical and mechanical consultants engaged by Landlord
         (collectively, "Landlord's Consultants"), such information as may
         reasonably be necessary to cause Landlord's Consultants to prepare and
         submit to Landlord all necessary drawings, plans and specifications
         covering the Tenant's Extra Work (such drawings, plans and
         specifications are hereinafter called "Tenant's Extra Work Plans").
         Tenant shall pay the reasonable fees and expenses of Landlord's
         Consultants to prepare Tenant's Extra Work Plans within ten (10)
         business days of Landlord's delivery of the billing statement(s)
         therefor.

                  (b)      Landlord agrees to construct the Tenant's Extra Work
         provided (a) the Tenant's Extra Work Plans are acceptable to Landlord
         in its sole discretion and approved in writing by it, and (b) Tenant
         has not defaulted under, or otherwise breached, the terms and
         provisions of this Lease.

                  (c)      Prior to commencing any Tenant's Extra Work, Landlord
         shall submit to Tenant for Tenant's approval, a written estimate of the
         cost of Tenant's Extra Work and any projected delay in the estimated
         Commencement Date resulting from the proposed Tenant's Extra Work
         (hereinafter called "Estimate"). Landlord shall not be obligated to
         proceed with Tenant's Extra Work until the Estimate is approved in
         writing by Tenant. Tenant shall have five (5) business days from
         Landlord's delivery of the Estimate to advise Landlord of Tenant's
         approval or disapproval thereof. If Tenant fails to timely approve the
         Estimate, then Tenant shall automatically be deemed to have disapproved
         the Estimate and therefore, Landlord shall have no obligation to
         perform Tenant's Extra Work. The cost incurred in the performance of
         Tenant's Extra Work is due and payable to Landlord within a reasonable
         period of time prior to such time as Landlord is obligated to pay its
         contractor for such work pursuant to its Construction Contract with
         such contractor (whether on a percentage of completion basis or
         otherwise). If Tenant fails timely to make any payments for Tenant's
         Extra Work, Landlord may immediately cease to perform the Tenant's
         Extra Work and any delays in the Commencement Date set forth in the
         Estimate shall nonetheless remain effective for all relevant purposes.
         For purposes hereof, Tenant's Extra Work shall be deemed to also
         include the following items: i) All subcontract costs


                                      B-3
<PAGE>


         and general conditions pertaining to the Tenant's Extra Work; and (ii)
         An overhead, profit and building supervision charge of nine percent (9
         %) of the total cost of Tenant's Extra Work.

         5.       RENT COMMENCEMENT DATE: Landlord and Tenant contemplate that
the Building and the Premises will be substantially complete on or about May 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 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.

                  (a)      FORCE MAJEURE DELAYS. If Landlord, as the result of
         any (i) strikes, lockouts or labor disputes, (ii) inability to obtain
         labor or materials or reasonable substitutes therefor, (iii) inclement
         weather which delays or precludes construction, acts of God or the
         public enemy, condemnation, civil commotion, fire or other casualty,
         (iv) shortage of fuel, (v) action or nonaction of public utilities or
         of local, state or federal governments, affecting the work, including,
         but not limited to, any delays in the permitting process as a result of
         the action or inaction or such governmental authorities, or (vi) other
         conditions similar to those enumerated above which are beyond the
         reasonable anticipation or control of Landlord, cannot reasonably
         perform any obligation on its part to be performed hereunder within the
         time periods herein specified (collectively, the "Force Majeure
         Delays"), then such failure shall be excused and not be a breach of
         Landlord's obligations under this Lease, and the deadline for
         performance shall be extended for a period equal to the period of
         delay, and Landlord will notify Tenant of the nature and probable
         duration of such delay. Landlord shall make reasonable efforts to
         minimize the impact of such delay.

                  (b)      TENANT DELAYS: If Landlord shall be delayed in
         Substantially Completing the Improvements as a result of any "Tenant
         Delays," then, the Commencement Date and the payment of Rent under the
         Lease shall not be affected or deferred on account of any such Tenant
         Delays. "Tenant Delays" shall mean any or all of the following:

                           i)       Tenant's failure to approve change orders on
                  a timely basis and/or to pay invoices (within five (5)
                  business days of submission thereof to Tenant) for excess
                  Total Project Costs in accordance herewith; or

                           ii)      Tenant's changes in the Preliminary Drawings
                  and/or Building Improvements Final Plans and Specifications;
                  or

                           iii)     The failure by Tenant, or any person, firm
                  or corporation employed by Tenant or its representatives or
                  agents, to cooperate with Landlord in completion of any work
                  in or about the Premises; or

                           iv)      Any other act or omission by Tenant or its
                  employees, representatives or agents; or

                           v)       Any delay in the Substantial Completion of
                  the Building Improvements occasioned by the Tenant
                  Improvements; or

                           vi)      Any delay in the Commencement Date resulting
                  from any Tenant Extra Work to the extent that such delay was
                  set forth in an Estimate and approved by Tenant;

                           vii)     Any delay in the Commencement Date resulting
                  from the acts or omissions of Tenant or its agents, employees,
                  representatives, invitees, contractors or subcontractors in
                  connection with Tenant's use or occupancy of the Premises.


                                      B-4
<PAGE>


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 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;


                                      B-5
<PAGE>


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.
