Premises:                The space cross-hatched on Exhibit B attached hereto
                         (the "Premises"), consisting of approximately 16,743
                         square feet of rentable area in the building (the
                         "Building") constructed on the tract of land (the
                         "Land") located in the City of Plymouth, County of
                         Hennepin, State of Minnesota, (the "Land") legally
                         described on Exhibit C attached hereto.


     WITNESSETH THAT, in consideration of the Lease for the Premises, the rents
agreed to be paid, and of all the other mutual covenant and agreements herein
contained,

IT IS AGREED:

     1.  PREMISES AND USE. Landlord hereby leases to Tenant and Tenant hereby
accepts and leases from Landlord, for the term set forth above, the Premises,
together with the right to use, in common with Landlord and other tenants of the
Building and their agents, employees and invitees, the parking areas, walkways,
driveways and any other areas, facilities or improvements located in or on the
Building or land and designed or intended to be used in common (the "common
areas").

     The Premises shall be used by Tenant for the manufacturing of medical
devices and or office, and or warehouse purposes, (provided, however, that
Landlord does not hereby make any warranty or representation, expressed or
implied, that the Premises may be used for such purposes under applicable
Building and zoning and other laws, ordinances and codes), and for no other
purpose, in compliance with all applicable federal, state and local laws,
ordinances, codes, rules, regulations and orders, and also in compliance with
the rules and regulations of Landlord which are attached hereto as Exhibit D, as
the same may from time to time be supplemented or amended. Tenant shall, at its
expense, make any and all alterations and improvements to the Premises required
at any time in order for the Premises and the use thereof to comply with such
laws, ordinances, codes, rules and regulations and orders. No part of the
Premises shall be used for any purpose which constitutes a nuisance or which is
dangerous, illegal or offensive, or which interferes with the general safety,
comfort and convenience of the Landlord and other tenants of the Building.

     2.  ACCEPTANCE OF PREMISES.  Tenant acknowledges that it has inspected the
Premises and accepts them in their present condition as suitable for the
purposes for which they are leased, and further acknowledges that no
representations as to the repair of the Premises, nor promises to alter, remodel
or improve the Premises, have been made by Landlord, except as may be provided
on the attached Exhibit E.

     If Landlord does not complete leasehold improvements, if any, to be
completed by Landlord, and deliver possession of the Premises on or before the
commencement date of this Lease, or if Landlord is unable for any other reason
to deliver possession of the Premises by such date, Landlord shall not thereby
be deemed to be in default hereunder, and shall not thereby be liable to Tenant
for any loss, damage, cost or expense suffered or incurred by Tenant, nor shall
the commencement date or the Term of this Lease be affected or changed thereby,
and Tenant agrees to accept possession of the Premises at such time as Landlord
is able to tender the same.

     3.  ADDITIONAL RENT.  In addition to Base Rent set forth above, Tenant
agrees to pay Landlord, at the time and place that the payments of Base Rent are
due and payable, Tenant's prorata share of (1) all real estate taxes and
installments of special assessments levied or assessed against the land and the
Building, due and payable in any calendar year falling in whole or in part
within the Lease Term, (2) premiums for casualty, rent loss and public liability
insurance which Landlord maintains with respect to the land

                                       2


and the Building, and (3) all expense for or on account of (i) lighting,
cleaning, removing snow from, policing and otherwise properly operating,
maintaining and repairing the parking area and other common areas, (ii)
providing water and other utilities to common areas and providing water or other
utilities to tenants which are not separately metered, (iii) maintaining and
repairing the structural portions and exterior of the Building, including
painting of the same, and landscaped portions of the land, (iv) window washing,
(v) making repairs and replacements to and of the heating, cooling, ventilating,
electrical and plumbing systems serving the Building, and (vi) management fees
(all of the items listed in clauses (1), (2) and (3) above being hereinafter
referred to as the "Shared Expenses." If Landlord makes any special improvements
during the term of this Lease in order to comply with any federal, state or
local law or governmental regulation, or to save energy or reduce maintenance
costs, the reasonable annual amortization of the cost thereof, with interest at
the lesser of twelve percent (12%) per annum or the highest rate permitted by
law, shall be deemed a Shared Expense in each of the calendar years during which
such amortization occurs. Tenant's prorata share of the Shared Expenses shall be
based on the number of square feet of rentable area in the Premises bears to the
total number of square feet of rentable area in the Building, including space
occupied by Landlord. "For purposes hereof, rentable area shall be computed by
measuring to the outside finished surface or permanent outer Building walls. The
rentable area of a Building shall be the sum of the rentable area of all
enclosed floors of the Building, including mechanical equipment floors,
penthouses, and the like." Tenant's prorata share of the Shared Expenses shall
be adjusted as of each January 1 during the Lease Term, based on Landlord's
estimate of the Shared Expenses for the ensuing calendar year, and on each such
January 1 and the first (1st) day of each month during such calendar year,
Tenant shall pay Landlord one-twelfth of Tenant's prorata share of such
estimated Shared Expenses. Within ten (10) days after Landlord shall have
determined the actual Shared Expenses for such calendar year, appropriate
adjustments shall be made between Landlord and Tenant. Tenant's prorata share of
Shared Expenses for the years in which this Lease commences and terminates shall
be prorated on a per diem basis. Shared Expenses shall be determined in
accordance with generally accepted accounting principles.

     In addition to the Base Rent set forth above, Tenant also agrees to pay to
Landlord, as additional rent, upon demand, all management fees, attorneys' fees
and other fees, and out-of-pocket costs and expenses if any, incurred by
Landlord in connection with this Lease, including without limitation, any such
fees, costs and expenses payable by Landlord to others for dealing with or
handling inquires by Tenant, for dealing with or handling delinquencies or
defaults by Tenant hereunder and for enforcing the provisions hereof, but
specifically excluding any such fees, costs and expenses payable by Landlord to
others for negotiating or preparing this Lease.

     4.  UTILITIES.  Tenant shall pay for all utilities that are now or in the
future shall be separately metered to the Premises, including gas, electricity,
water and sewer and any other utility service used within the Premises during
the Term of this Lease.

     5.  MAINTENANCE BY LANDLORD.  Subject to the provisions of paragraph 3
hereof, Landlord shall, at its expense, keep the structural parts of the
Building in good order, safe condition and repair, including the exterior walls,
roof, floor, foundation and

                                       3


interior support column except as otherwise herein and more specifically
stated in paragraph 7 of this Lease.

     6.  MAINTENANCE BY TENANT. Tenant shall be solely responsible for providing
and paying for its own interior (i.e. within the Premises) janitorial services,
including without limitation window washing, for the Premises. Further, Tenant
shall be solely responsible for the maintenance and repair of the following
items: the interior of the Premises; entrance and interior doors; overhead doors
entering the Premises; heating, cooling, ventilating, sprinkler, electrical and
plumbing fixtures and equipment located in or serving the Premises; the
replacement of broken glass located in or forming a part of the perimeter of the
Premises; and the interior of the loading dock area portion of the Premises.
Tenant shall maintain in full force and effect during the Lease Term, and
provide Landlord with a copy of, a service contract with respect to any utility
fixtures and equipment which Tenant is required to maintain and repair pursuant
hereto, or, in the alternative, shall provide Landlord with periodic
certifications, as requested by landlord, that Tenant has performed all such
required maintenance and repair. If Tenant does not provide such certificate
indicating a satisfactory maintenance program, Landlord shall notify Tenant in
writing of such breach of contract and Tenant shall within fifteen (15) days
provide such certificate or proof of maintenance acceptable to Landlord. In the
event Tenant does not notify landlord in writing within specified time period
Landlord shall provide such maintenance and bill Tenant therefore, which costs
shall be payable upon receipt of invoice.

     7.  GENERAL REPAIR.  In the event that any act or omission resulting in the
necessity for maintenance or repair of the land, Building and/or Premises
involves the negligence, gross negligence or deliberate act of a party to the
Lease, not normally obligated to perform such maintenance or repair, or any
agent, employee or invitee of such party, then such party shall be responsible
for performing the maintenance or repair or paying for the same. Nothing in this
paragraph 7 is intended or shall be construed as negating or modifying the
waiver of subrogation provisions contained in paragraph 9 below as to acts or
omissions covered by fire and extended risk or personal property insurance
policies.

     8.  INSURANCE BY TENANT.  Landlord, and Landlord's agents and employees,
shall not be liable to Tenant, or those claiming through or under Tenant, for
injury, death, property damage, burglary, theft or disappearance occurring in,
on or about the Premises, the Building, and the land and appurtenances thereto,
and Tenant shall indemnify and hold them harmless from any claim, damage, cost
and expense (including attorneys' fees) or liability arising out of any injury,
death, property damage, burglary, theft or disappearance occurring in, on or
about the Premises to Tenant or any agent, employee or invitee of Tenant, unless
due to Landlord's gross negligence or willful misconduct.

     The Tenant, at the Tenant's sole cost and expense, shall maintain for the
mutual benefit of the Landlord and the Tenant, general public liability
insurance against claims for personal injury, death or property damage occurring
upon, in or about the Premises, such insurance to afford protection in a
combined single limit of not less than $2,000,000.00. All policies of insurance
shall be in form and substance satisfactory to Landlord, shall be written with
companies satisfactory to the Landlord, and shall provide for at least ten (10)

                                       4


business days written notice to Landlord prior to cancellation. Such policies,
or certificates thereof, shall be delivered to landlord prior to the
commencement of the Lease Term; and evidence of any renewal of such insurance
shall be delivered to Landlord not less than thirty (30) days prior to the
expiration of the term of such coverage.

     The Tenant covenants that it will not do or permit to be done, nor keep nor
permit to be kept upon the Premises, anything that will contravene the policy or
policies of insurance against loss by fire or other causes, or which will
increase the rate of fire or other insurance on the Building. Should any act of
the Tenant so increase said rate, then, in addition to the rentals hereinabove
provided for, the Tenant shall be liable for such additional premium, which
shall be payable when billed as additional rent, collectible in the same manner
as the rents hereinabove provided for. Tenant covenants that under no
circumstances will it keep or permit to be kept, do or permit to be done, in or
about the Premises, anything of a character so hazardous as to render it
difficult, impracticable or impossible to secure such insurance in companies
acceptable to the Landlord, and further, immediately upon notice, to remove from
the Premises and/or to desist from any practice deemed by the insurance
companies or the Association of Fire Underwriters as so affecting the insurance
risk.

     Anything contained in this Lease to the contrary notwithstanding, Tenant
agrees that it shall look solely to the estate and property of Landlord in the
Land and Building of which the Premises form a part, for the collection of any
judgment (or other judicial process) requiring the payment of money by Landlord
for any default or breach by Landlord of any of its obligations under this
Lease, subject, however, to the prior rights of any ground or underlying
landlord or the holder of any mortgage covering the Building or of Landlord's
interest therein. No other assets of Landlord shall be subject to levy,
execution or other judicial process for the satisfaction of Tenant's claim. This
provisions shall not be deemed, construed or interpreted to be or constitute an
agreement, express or implied, between Landlord and Tenant that Landlord's
interest hereunder and in the Building shall be subject to impressment of an
equitable lien or otherwise. Nothing herein contained shall be construed to
limit any right of injunction against Landlord, where appropriate.

     9.  WAIVER OF SUBROGATION.  Landlord, on its own behalf and on behalf of
anyone claiming through or under it, hereby waives and releases all claims,
liabilities and causes of action against Tenant and the agents, employees and
invitees of Tenant, and Tenant, on its own behalf and on behalf of anyone
claiming through or under it, hereby waives and releases all claims, liabilities
and causes of action against Landlord and the agents, employees and invitees of
Landlord, for loss or damage to, or destruction of, the Premises or any portion
thereof, the Building and other improvements situated on the land, as well as
the improvements, fixtures, equipment, supplies, merchandise and other property
located in, upon or about the Premises, resulting from fire, explosion or other
perils included in standard fire and extended coverage insurance, whether caused
by the negligence of any of said persons or entities or otherwise.

     10. IMPAIRMENT OF USE.  In the event of damage to the Premises during the
term hereof by fire, the elements or other casualty, Landlord shall restore the
Premises, at its cost, with reasonable dispatch unless Landlord shall, within
sixty (60) days of the date of the occurrence of such fire or casualty, elect
not to rebuild.  In the event Landlord elects

                                       5


not to rebuild as above set forth, then this Lease shall cease and terminate as
of the date of such damage and destruction, any rental prepaid for the period
after such date shall be refunded to Tenant, and Tenant shall have no claim
against Landlord for the value of any unexpired Term of this Lease. During any
such restoration, to the extent the Premises shall be untenantable or it shall
be impracticable to conduct business therein, the rent shall abate
proportionately. In the event of such damage to the Premises, Landlord shall not
be responsible for repairing or restoring leasehold improvements, personal
property, machinery or equipment of Tenant.

     11.  ASSIGNMENT.  Tenant shall not assign, sublease, mortgage, pledge or in
any manner transfer the Premises or any part thereof or this Lease without the
prior written consent of Landlord. If the Tenant is a partnership, corporation
or other legal entity, any change in the partnership interest, stock or legal or
beneficial ownership of such partnership, corporation or other entity shall be
deemed an assignment of this Lease for purposes of this paragraph 11. Landlord
agrees that Landlord's consent to a proposed assignment or sublease shall not be
unreasonably withheld or delayed. Tenant acknowledges that Landlord may withhold
such consent if (a) the proposed assignee or subtenant intends to use the
Premises for a use which is not permitted under paragraph 1 of this Lease, or
(b) the financial condition and reputation of the proposed assignee or subtenant
is not reasonably satisfactory to Landlord. If Landlord consents to a proposed
assignment or sublease, Tenant shall remain fully liable for and shall not be
released from any or all of its obligations and liabilities under this Lease.

     12.  ALTERATIONS AND MECHANIC'S LIENS. Tenant shall not make any
alterations or improvements to the Premises without prior written approval of
the Landlord, which approval may be conditioned on the Tenant's compliance with
such requirements with respect to such alterations as Landlord may impose,
including without limitation the furnishing of a bond or other security
satisfactory to Landlord against mechanics' liens and claims therefore. Any such
work approved by Landlord shall be done in good, workmanlike manner in
conformance with applicable Building codes, free and clear of mechanics' liens
and claims therefore. Any alterations and improvement shall become the property
of Landlord upon being affixed to the Premises and all right, title and interest
of the Tenant therein shall immediately cease, provided, however, that if
directed by Landlord, Tenant, at its expense shall remove any such alterations
and improvements from the Premises at the expiration of the Lease Term, and
repair any damage to the Premises or the Building caused by the installation or
removal of such alterations and improvements. Tenant may remove from the
Premises at the expiration of the Lease Term, the trade fixtures purchased and
installed by Tenant. Tenant shall be required to leave the Premises in as good
as, or better condition. However the removal of any and all fixtures shall be
approved by Lessor prior to Lessee commencing such removal, provided Lessee, at
its expense, repairs any and all damage associated with said removal. Landlord
hereby specifically approves the installation of the Tenant's sign shown on
Exhibit F attached hereto. Landlord at its discretion during the Term of this
Lease shall have the right to change or modify all sign criteria approved herein
or otherwise adopted during the Term of this Lease.

     13.  SURRENDER. Upon the expiration or termination of this Lease, Tenant
shall peaceably surrender the Premises broom-clean, in good condition and
repair, fire and other casualty, reasonable wear and tear (which term shall not
include wear and tear resulting

                                       6


from acid, salt or other substances used by Tenant in the operation of its
business, or installations made by Tenant) excepted. Tenant shall, at its
expense, leave the Premises as required in paragraph 12 hereof and shall also
remove all of its trade fixtures, personal property, equipment and signs from
the Premises. Any property not removed on or before the expiration or
termination of this lease shall be deemed to have been abandoned. Any damage to
the Premises caused in the removal of such items shall be repaired by and/or at
the expense of Tenant.

     14.  DEFAULT OF TENANT AND REMEDIES.

          A.   Events of Default and Remedies. If Tenant fails to pay any monies
     due hereunder or to perform any other of the terms, covenants, conditions
     or obligations of this Lease to be performed by Tenant, or if any
     proceeding is commenced by or against Tenant for the Purpose of subjecting
     the assets of Tenant to any law relating to bankruptcy or insolvency or for
     an appointment of a receiver of Tenant or any of Tenant's assets, or if
     Tenant makes a general assignment of Tenant's assets for the benefit of
     creditors, then in any such event, Tenant shall be in default hereunder,
     and Landlord shall have the right, at its option, in addition to any other
     rights and remedies it may have hereunder, or at law or in equity or by
     statue or otherwise, to terminate this Lease as to all future rights of
     Tenant, and have, regain, repossess and enjoy the Premises. Should Landlord
     at any time terminate this Lease for any such default, in addition to any
     other remedies Landlord may have, Landlord may recover from Tenant and
     Tenant shall indemnify Landlord against, all loss of rents and other
     damages Landlord may incur by reason of such default, including the cost of
     recovering and reletting Premises, and reasonable attorneys' fees.

          B.   Right of Landlord to Cure Default of Tenant. Landlord may, at its
     option, instead of exercising any other rights or remedies available to it
     in this Lease or otherwise, spend such sums of money as is reasonably
     necessary to cure any default of Tenant herein and the amount so spent, and
     cost incurred, including reasonable attorneys' fees in curing such default,
     shall be paid by Tenant, as additional rent, upon demand.

          C.   Legal and Other Expenses.  In the event suit shall be brought for
     recovery of possession of the Premises, for the recovery of rent or any
     other amount due under the provisions of this Lease, or because of the
     breach of any other covenant herein contained on the part of Tenant to be
     kept or performed, Tenant shall pay Landlord all expenses incurred
     therefore, including reasonable fees of attorneys.

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

          E.   Overdue Payments. If Tenant fails to pay an installment of rent
     or any other sum due and payable to landlord on or before the first fifth
     day of the

                                       7


     calendar month when such installment becomes due and payable, Tenant
     shall pay to Landlord a late charge (to cover Landlord's administrative and
     overhead expenses of processing late payments) equal to the greater of one
     hundred dollars ($100.00) or five percent (5%) of the amount of such
     installment and, in addition, such unpaid installment shall bear interest
     at the rate of twelve percent (12%) per annum from the date such
     installment became due and payable to the date of payment thereof by
     Tenant; provided, however, that nothing herein contained shall be construed
     or implemented in such a manner as to allow Landlord to charge or receive
     interest in excess of the maximum legal rate then allowed by law.  Such
     late charge and interest shall constitute additional rent hereunder due and
     payable with the next monthly installment of rent.  Tenant shall be granted
     one (1) five (5) day grace period per calendar year without late fees or
     interest charges.

     15.  SUBORDINATION. At the option of the holder or holders of any such
mortgage, ground lease or other security, this Lease shall be subordinate to any
and all mortgages, ground leases, or other security covering the Premises,
including any renewal, modifications, consolidations, replacements and
extensions thereof, now or hereafter recorded against the Premises, the Building
or land. Tenant agrees to execute any instruments which may be deemed by the
Landlord or such holder or holders as necessary or desirable to further effect
the subordination of this Lease to any such security.

     Tenant shall, from time to time, and within ten (10) days after receipt of
a request from Landlord therefore, execute and deliver to Landlord, or to any
holder or proposed holder of a security interest in the Premises or to any
proposed purchaser of the Premises, a certificate in recordable form, certifying
that this lease is in full force and effect, and that there are no offsets
against rent nor defenses to performance of Tenant under this Lease, or setting
forth any such offsets or defenses claimed by Tenant, as the case may be, and
certifying as to such other matters as is reasonably requested. Tenant shall
make no charge for executing and delivering such certificate.

     In the event the original Lease hereunder, or any successor owner of the
Building, shall sell or convey the Building, all liabilities and obligations on
the part of the original Landlord, or such successor owner, under this Lease
accruing thereafter shall terminate, and thereupon all such liabilities and
obligations shall be binding on the new owner. Tenant agrees to attorn to such
new owner in writing if requested by Landlord to do so.

     Landlord hereby reserves the right to sell, assign or transfer this Lease
upon the condition that in such event this Lease shall remain in full force and
effect, subject to the performances by Tenant of all the terms covenants and
conditions on its part to be performed. In the event that such purchaser,
assignee or transferee agrees to perform all the terms, covenants and conditions
of Landlord pursuant to this Lease which are to be performed by Landlord from
and after the effective date of such sale, assignment or transfer then, upon any
such sale, assignment or transfer, other than merely as security, Tenant agrees
to look solely to the purchaser, assignee or transferee with respect to all
matters in connection with this Lease and the transferor Landlord shall be
released from any further obligations hereunder.

                                       8


     Notwithstanding anything in this paragraph 15 to the contrary, Landlord
agrees to use reasonable efforts to procure a non-disturbance agreement in favor
of Tenant from any future first mortgagee or ground lessor of the Building.
Tenant understands that (a) Landlord shall not be obligated to expend any funds
to procure such agreement and (b) Tenant's obligations under this Lease are not
conditioned on Landlord's obtaining such agreement from any such mortgagee or
ground lessor and Tenant's sole and exclusive remedy for Landlord's failure to
use such efforts shall be a claim for actual damages directly caused as a result
of such breach (excluding any indirect, consequential or punitive damages),
which damages shall not exceed the amount of Rent payable under this Lease from
and after the date of said default, and in no event shall Tenant be entitled to
terminate this Lease or to any abatement of Rent as a result of such breach.
Such non-disturbance agreement shall be in such mortgagee's or ground lessor's
customary form.

     16.  HOLDING OVER.  In the event Tenant remains in possession of the
Premises after the expiration of this Lease, it shall be deemed to be occupying
the premises as a tenant from month-to-month, subject to all the conditions,
provisions and obligations of this Lease insofar as the same can be applicable
to a month-to-month tenancy; provided, however, that the Base Rent required to
be paid by Tenant during any holdover period shall be 150% of the amount of the
Base Rent set forth above.  Any holding over, however, pursuant to this Article
shall not be considered as constituting a renewal or extension of this Lease.

     17.  NOTICES. Any notice required or permitted under this Lease shall be
deemed sufficiently given or served if sent by recognized national overnight
delivery service or by registered or certified mail, return receipt requested,
postage prepaid, to Tenant at its address set forth above and to Landlord in
care of Cornerstone Real estate Advisers, Inc., 311 South Wacker Drive, Suite
980, Chicago, Illinois 60606, with a copy to the address then fixed for the
payment of rent, and either party may by like written notice at any time
designate a different address to which notices shall subsequently be sent. Such
notices shall be deemed received by the party to whom they are sent on the fifth
day following the date of delivery to the United States Post Office Department.

     18.  ENTRY BY LANDLORD. Upon reasonable notice, Tenant agrees to permit the
Landlord and any authorized representatives of the Landlord to enter the
Premises at all times during usual business hours or at any other time in case
of emergency, to inspect the same and to make any repairs or perform any work
deemed necessary or desirable by the Landlord. During the progress of any such
work, the Landlord may keep and store upon the Premises all necessary materials,
tools and equipment. The Landlord shall not in any event be liable for
inconvenience, annoyance, disturbance, loss of business or other damage to the
Tenant.

     19.  SUCCESSORS AND ASSIGNS.  The terms, covenants and conditions hereof
shall be binding upon and inure to the benefit of the parties hereto, and their
respective heirs, legal representatives, successors and assigns.

     20.  HAZARDOUS WASTE. Tenant shall not (either with or without negligence)
cause or permit the escape, disposal or release of any biologically or
chemically active or other hazardous substances, or material. Tenant shall not
allow the storage or use of such substances or materials in any manner not
sanctioned by law for the storage and use of such substances or material, nor
allow to be brought into the Building any such materials or substances except to
use in the ordinary course of Tenant's business, and then only after written
notice is given to Landlord of the identity of such substances or materials.
Without limitation, hazardous substances and materials shall include those
described in the Comprehensive Environmental Response, Compensation and
Liability Act of 1980, as amended, 42 U.S.C. Section 9601 et seq., the Resource
Conservation and Recovery Act, as amended, 42 U.S.C. Section 6901 et seq., any
applicable state or local laws and the regulations adopted under these acts. If

whether or not there has been any release of hazardous material, then the
reasonable costs thereof shall be reimbursed by Tenant to Landlord upon demand
as additional charges if such requirement applies to the Leased Premises. In
addition, Tenant shall execute affidavits, representations and the like from
time to time at Landlord's request concerning Tenant's best knowledge and belief

Premises. In all events, Tenant shall indemnify Landlord in the manner elsewhere
provided in this lease from any release of hazardous material in or about the

to the contrary, under no circumstances shall Landlord's liability or that of

obligations arising out of or in connection with the Lease or for any breach of
the terms or conditions of this Lease (whether written or implied) exceed
Landlord's equity interest in the Building. Any judgments rendered against
Landlord shall be satisfied solely out of proceeds of sale of Landlord's
interest in the Building. No personal judgment shall lie against Landlord upon
extinguishment of its rights in the Building provided that the new landlord
assumes the Landlord's obligations under this Lease, and any judgments so
rendered shall not give rise to any right of execution or levy against
Landlord's assets. The provisions hereof shall inure to Landlord's successors
and assigns including any Lender. The foregoing provisions are not intended to
relieve Landlord from the performance of any of Landlord's obligations under
this Lease, but only to limit the personal liability of Landlord in case of
recovery of a judgment against Landlord; nor shall the foregoing be deemed to
limit Tenant's rights to obtain injunctive relief or specific performance or
other remedy which may be accorded Tenant by law or under this Lease.

     22.  GENERAL.

     express waiver shall affect any default other than the default specified in
     the express waiver and that only for the time and to the extent therein

     under this Lease, Landlord shall have the right to terminate this Lease
     (without payment of any termination fee or penalty by or to Landlord or
     Tenant) by giving Tenant written notice of termination at any time
     thereafter, which notice shall specify the actual effective date of
