Exhibit 10.18

                                 LEASE AGREEMENT


CONTROL  DATA  SYSTEMS,  INC.,  (hereinafter  referred  to  as  "Landlord")  and
DYNAMARK,  INC.,  (hereinafter  referred to as  "Tenant"),  entered into a Lease
dated April 6, 1992,  covering  premises at 4290 Fernwood  Avenue,  Arden Hills,
Minnesota.

NOW THEREFORE,  Landlord and Tenant agree to terminate the subject April 6, 1992
Lease  in its  entirety  as of the  Commencement  Date  (except  as to any  sums
remaining  owing,  whether  actual or  contingent)  and  enter  into a new Lease
Agreement, the terms and conditions of which are stated as follows:

1.       PARTIES.

         This Lease is made and  entered  into this 1st day of May 1995,  by and
between CONTROL DATA SYSTEMS,  INC.  (hereinafter referred to as "Landlord") and
DYNAMARK, INC., hereinafter referred to as "Tenant").

2.       PREMISES.

         In  consideration  of the rents and covenants  herein agreed to be paid
and  performed,  Landlord  hereby leases to Tenant and Tenant hereby leases from
Landlord, on the terms and conditions  hereinafter set forth, that certain space
(the "Premises")  consisting of approximately forty eight thousand eight hundred
four  (48,804)  rentable  square  feet and other  improvements  located  at 4290
Fernwood  Avenue,  Arden Hills,  Minnesota.  The Premises are more  particularly
designated  on the plan  attached  hereto  as  Exhibit A and made a part of this
Lease Agreement.

3.       TERM.

         The term of this Lease shall be for a period commencing on May 1, 1995,
(the  "Commencement  Date"),  and ending at midnight on August 31, 2005,  unless
sooner terminated as hereinafter provided.

4.       BASE RENT.

         (a) For the period from the  Commencement  Date of this Lease Agreement
through  July 31,  1997,  Tenant  agrees  to pay Base Rent for the  Premises  in
monthly  installments  at the rate of thirty-four  thousand five hundred dollars
($34,500.00) per month.
         Landlord  shall provide  during this period,  included in the Base Rent
listed above at no additional cost to Tenant,  the following items:  parking lot
and grounds  maintenance,  property insurance,  property tax payments (up to the
amount paid in 1992),  sewer and water, and property  management  services.  The
Base Rent shall be adjusted  periodically  as necessary to reflect any increases
or decreases in Tenant's actual pro rata share of real estate taxes 




attributable  to the  Premises.  Taxes  allocated to the Premises are  currently
deemed to be 6.663713898% of the taxes and assessments for the entire complex in
which the Premises are located.  Tenant may  challenge  such  allocation  if the
circumstances  concerning  the  Premises and its  relationship  to the taxes and
assessments change so as to make such allocation inequitable. If Landlord incurs
any  reasonable  expenses  as a result of real  estate  tax  appeals  or related
actions  which benefit  Tenant in the lowering of the Base Rent,  Tenant will be
responsible for its pro rata share of these expenses.
         During  this  period,  Tenant  shall  also pay all costs for  utilities
including electricity,  chilled water, heating, custodial services and all other
costs not specifically covered by Landlord and addressed herein. Such costs will
be invoiced  at  Landlord's  actual  cost and will not  contain  any  additional
charges.
         (b) Beginning  August 1, 1997 and  thereafter  for the remainder of the
Term of this Lease Agreement, Base Rent shall be paid according to the following
schedule:

                                   Annual                  Base
           Months               Base Rent/RSF            Rent/Month
         ---------              -------------            ----------
          1  -  36                 $6.89                 $28,021.63
         37  -  72                 $7.24                 $29,455.08
         73  -  97                 $7.54                 $30,665.18

         Tenant shall pay as Additional Rent three dollars and twenty-nine cents
($3.29) per rentable  square foot per annum as a fixed charge for Tenant's share
of Operating Expenses (as defined in the OPERATING  EXPENSES  section),  payable
monthly  with Base Rent.  On each  January 1 of the Term  after  August 1, 1997,
Tenant's pro rata share of Operating  Expenses shall increase three percent (3%)
over  Tenant's  pro rata share for the  previous  year,  with the  exception  of
Tenant's  pro rata share of real estate  taxes  which  shall  reflect the actual
increases or decreases.
         During  this  period,  Tenant  shall  also pay all costs for  utilities
including  electricity,  water and sewer,  chilled water usage and availability,
heating,  custodial  services  and all other costs not  specifically  covered by
Landlord and addressed herein.  If Landlord incurs any reasonable  expenses as a
result of real estate tax appeals or related actions which benefit Tenant in the
lowering  of  the  Additional  Rent  for  real  estate  taxes,  Tenant  will  be
responsible for its pro rata share of these expenses.
         (c) Said rent is subject to late charges and other terms and conditions
of this  Agreement.  Tenant  further  agrees  to pay its pro  rata  share of any
increases in expenses  attributable  to a change in law relating to the building
and its usage.  Monthly  rental  shall be payable in advance on the first day of
each month during the term of this Lease,  without  notice or demand and without
any deduction,  off-set,  or abatement,  except as expressly provided herein, in
lawful money of the United  States to the Landlord at the address  stated herein
for notices or to such other  persons or such other  places as the  Landlord may
designate  to Tenant in  writing.  Rent not paid within ten (10) days of the due
date shall be subject to a late  charge  equal to the lesser of 

                                       2



five (5) percent of the amount unpaid or the maximum  allowable under applicable
law,  which amount shall be charged  against each  installment  of rent not paid
when due. In addition,  any installment of rent not paid within ten (10) days of
the due date shall bear  interest at the rate of twelve  (12)  percent per annum
from the due date  until  paid,  which  interest  shall be  immediately  due and
payable as additional  rent. Any items of additional rent shall be invoiced on a
monthly basis by Landlord and shall be payable by Tenant within fifteen(15) days
of the date of such invoice.

5.       OPERATING EXPENSES

         (a)  Operating  Expenses  as  Additional  Rent.  During the Term of the
Lease,  Tenant shall pay to Landlord as additional rent,  without any set-off or
deduction  except as described  herein,  the fixed charge specified in Section 4
(b) above for a prorata  share  ("Tenant's  Proportionate  Share")  of all costs
which  Landlord  may incur in owning,  maintaining  and  operating  the premises
("Operating Expenses").
         (b) Definition of Operating  Expenses.  The term  "Operating  Expenses"
shall mean all of the following: (i) all of Landlord's direct costs and expenses
of  operation,  repair and  maintenance  of the  Premises,  the property and the
common areas and supporting facilities,  as determined by Landlord in accordance
with generally  accepted  accounting  principles or other recognized  accounting
principles,  consistently  applied;  (ii) costs, or a portion thereof,  properly
allocable to the Premises,  property or common areas of any capital improvements
made to the  Premises,  property  or common  areas by  Landlord  which  comprise
labor-saving  devices  or other  equipment  intended  to improve  the  operating
efficiency of any system within the Premises,  property or common areas (such as
an energy management computer system) to the extent of cost savings in Operating
Expenses as a result of the device or  equipment,  as  reasonably  determined by
Landlord; and (iii) costs properly allocable to the Premises, property or common
areas of any capital improvements made to the Premises, property or common areas
by Landlord that are required under any  governmental law or regulation that was
not applicable to the Premises,  property and common areas at the time they were
constructed,  or that are  reasonably  required  for the  health  and  safety of
tenants in the property or Premises, the costs, or allocable portion thereof, to
be  amortized  over its useful life as  reasonably  determined  by Landlord  and
Tenant will pay Tenant's  Proportionate Share based on the time remaining in the
lease term,  together with interest upon the unamortized balance at the interest
rate or such higher rate as may have been paid by Landlord on funds borrowed for
the  purpose of  constructing  the  capital  improvements.  The term  "Operating
Expenses"  shall include the costs of all utilities  (including  surcharges) for
the  property  and  Premises;  the  cost  of all  insurance  which  Landlord  or
Landlord's  lender deems  necessary  for the property and  Premises;  a property
management  fee equal to ten percent (10%) of Operating  Expenses;  and the Real
Property Taxes. If Landlord elects to self-insure or includes the Premises under
blanket  insurance  policies  covering  multiple   properties,   then  the  term
"Operating   Expenses"   shall   include   the  portion  of  the  cost  of  such
self-insurance properly allocated by Landlord to the Premises.  Without 

                                       3



limiting the foregoing,  Operating Expenses shall include the costs set forth on
Exhibit C attached hereto, showing the breakdown of the initial $3.29 per square
foot charge. After August 1, 1997, Landlord agrees not to unreasonably  withhold
its agreement to modifications  of the services  provided by Landlord as part of
Operating Expenses, as requested by Tenant, so long as such modifications do not
result in increased  costs to Landlord,  deferred  maintenance  of the Premises,
increased casualty or theft risk to property or premises,  or other detriment to
Landlord;  and upon such modification of services the fixed charge for Operating
Expenses  shall be  appropriately  adjusted to reflect the reduced or  increased
costs to Landlord of providing such services at the time of such modification.
         (c) Exclusions From Operating Expenses.  The term "Operating  Expenses"
shall not include (i) costs paid directly by Tenant; (ii) principal and interest
payments on loans secured by deeds of trust  recorded  against  property;  (iii)
real estate sales or leasing brokerage  commissions;  or (iv) executive salaries
of off-site  personnel  employed by Landlord  except for the charge (or pro rata
share) of the manager of the  property and  building;  (v) any costs or expenses
resulting  from the  presence of Hazardous  Substances  as are  attributable  to
Tenant, (as described in Exhibit B) on the date hereof or at any time during the
Term.

6.       OPTION TO EXTEND LEASE.

         Tenant  shall have the right and option (the  "Option")  to extend this
Lease for all (but not part) of the Premises, as hereinafter  provided,  for two
(2) periods of five (5) years each  (hereinafter  referred  to as "Renewal  Term
One" and  "Renewal  Term Two")  provided  that (i) there is not then an Event of
Default at the time of exercise of the Option nor at the  commencement of either
of the Renewal Terms;  or (ii) that Tenant has not received  written notice from
Landlord of a default in rent  payments more than five (5) times during the last
two (2) years of the lease term or renewal period.  Tenant's right to extend for
any  Renewal  Term shall  lapse  without  further  act or deed if Tenant has not
exercised its option to extend for all available preceding Renewal Terms.
         The  Option  shall be  exercised  by Tenant  giving  written  notice to
Landlord of Tenant's  intention  to exercise  said Option on or before that date
which is not more than twelve (12) months nor less than nine (9) months prior to
the then applicable  expiration date for the Term.  Unless Landlord has received
such written  notice of Tenant's  intention to exercise  said Option  within the
time period specified herein,  then Landlord shall have no further obligation to
offer the  Premises to the  Tenant.  If Tenant has not  exercised  its Option to
extend the Terms as  outlined  herein,  Landlord  shall be  entitled to show the
Premises at least nine (9) months prior to the expiration of each Term and offer
the  Premises for lease to any other  prospective  tenants.  Landlord  will give
Tenant at least 24 hours notice prior to such showings to  prospective  tenants.
The Option  contained  herein is personal to Tenant and shall not be assigned or
sublet to  another  party,  except as to such  party  that  purchases  Tenant or
Tenant's assets.

                                       4



         Rental  rates will be at then Fair Market Rate,  but, in no case,  less
than the current Base Rent then in effect for the Premises. The Fair Market Rent
shall be established by agreement between Landlord and Tenant in accordance with
the FAIR MARKET RENT  DEFINITION  section or, failing  agreement,  in accordance
with the ARBITRATION PROCEDURES section.

7.       FAIR MARKET RENT DEFINITION

         "Fair  Market  Rent" shall mean the base rent that the  Landlord  would
receive as of the commencement  date in question if it were to lease to a tenant
with a credit  standing  which Landlord  reasonably  determines is comparable to
that of Tenant for similar  sized  space,  similar  leasehold  improvements  and
similar other terms and conditions.  For purposes of the  determination of "Fair
Market  Rent," it shall be assumed  that  Landlord  and  Tenant are each  ready,
willing  and able to enter into such a lease but are under no  compulsion  to do
so.

8.       ARBITRATION PROCEDURES

         The parties to this Lease will initially attempt to agree upon the Fair
Market  Rate.  If they have been unable to so agree  within the period that they
are required to agree as to such matter  under the Lease,  then either party may
request by written  notice to the other party  ("Arbitration  Request") that the
matter be determined by binding  arbitration by an arbitration  board consisting
of three reputable MAI appraisers who are recognized  experts  regarding  office
leases in the Twin Cities area. One arbitrator  will be appointed by each party,
and each such  arbitrator  will have no  material  financial  or other  business
interest in common with the party selecting such arbitrator. If a party fails to
appoint an  arbitrator  and notify the other  party of such  appointment  within
thirty (30) days after the Arbitration Request is made, then the arbitrator that
was  appointed  by the other party  within  such 30-day  period will be the sole
arbitrator.  If two  arbitrators  are  properly  appointed  and such  first  two
arbitrators  are unable to agree on a third  arbitrator  within thirty (30) days
after the appointment of the second arbitrator,  then such third arbitrator will
be appointed by the presiding  judge of Ramsey County  District Court, or by any
person to whom such presiding judge formally  delegates the matter,  or, if such
methods of appointment fail, by the American Arbitration Association.
         The parties will submit a copy of this Lease to the sole  arbitrator or
the three  arbitrators,  as the case may be. In  establishing  the definition of
Fair Market  Rent,  the  arbitrator  or  arbitrators  shall  apply the  standard
described in the FAIR MARKET RENT  DEFINITION  section.  If the  arbitration  is
conducted  by a sole  arbitrator,  such sole  arbitrator  will render his or her
determination  of the Fair Market Rate applicable  during the period in question
to the parties by the  thirtieth  (30th) day after the  Arbitration  Request was
made. If the arbitration is conducted by three arbitrators, each arbitrator will
submit his or her determination(s) of the Fair Market Rate applicable during the
period in question in a sealed  envelope by the  thirtieth  (30th) day following
appointment of the last arbitrator, and any determinations not submitted by such
time  shall  be  disregarded.  In such  cases,  the  parties  will  

                                       5



meet on such thirtieth  (30th) day (or if it is not a business day, on the first
business day  thereafter) at the office of Landlord,  or such other place as the
parties  may  agree,  and  simultaneously  deliver  the  determinations.  If the
determinations of at least two of the arbitrators are identical in amount,  such
amount will be deemed the decision of the arbitrators.  If the  determination of
the three  arbitrators  are  different  in amount,  the  decision as to the Fair
Market Rate will be independently determined as follows:
         (i) If neither the highest nor lowest  determination  differs  from the
middle  determination  by  more  than  fifteen  (15%)  percent  of  such  middle
determination,  then the decision  will be deemed to be the average of the three
determinations; and
         (ii) If clause (i) does not apply,  then the decision will be deemed to
be the  average of the middle  determination  and the  determination  closest in
amount to such middle determination.
         The decision of the arbitrators, determined as above set forth, will be
final and nonappealable.  The fees and expenses of the arbitrator or arbitrators
will be shared  equally by Landlord  and Tenant.  During the period of time that
any  arbitration  is pending  under this  Lease,  the parties to this Lease will
continue to comply with all those terms and provisions  that are not the subject
of the arbitration.

9.       USE.

         Tenant  shall use the Premises  only for general  office use, as a data
processing center and other reasonably related activities,  or only as otherwise
outlined  and  stated  in  this  lease  and for no  other  purpose  without  the
Landlord's prior written consent. Tenant shall not do, bring or keep anything in
or about the Premises that will cause a cancellation  of any insurance  covering
the Premises or the building in which the  Premises are located;  provided  that
Tenant's use for those purposes specified in the preceding sentence shall not be
prohibited. If the rate of any insurance carried by the Landlord is increased as
a result of Tenant's  use,  Tenant  shall pay to  Landlord  within ten (10) days
after written  demand from  Landlord,  the amount of any such  increase.  Tenant
shall  comply with all laws  concerning  the  Premises  or  Tenant's  use of the
Premises,  including  without  limitation,  the  obligation  at Tenant's cost to
alter,  maintain,  or restore the Premises in compliance and conformity with all
laws  relating to the  condition,  use, or  occupancy  of the Premises by Tenant
during the term of this Lease  provided that Tenant shall not be obligated  (nor
shall Landlord) to make any material capital improvements required by such laws,
ordinances,  orders,  rules and  regulations.  For  purposes of this  clause,  a
"material capital improvement" shall mean any capital improvement,  or series of
capital  improvements  within any calendar  year,  costing in excess of $25,000.
Tenant  shall not use or permit the use of the  Premises in any manner that will
tend to create waste or a nuisance or, if there shall be more than one tenant of
the building containing the Premises, which shall unreasonably disturb any other
tenant.  Tenant hereby acknowledges that neither the Landlord nor the Landlord's
agent has made any representation or warranty to Tenant as to the suitability of
the Premises for the conduct of Tenant's business.

Lease.
         (b)      Personal Property Taxes.
                  Tenant shall pay prior to the  delinquency  all taxes assessed
against and levied upon the trade  fixtures,  furnishings,  equipment  and other
personal property of Tenant contained in the Premises.  Tenant shall endeavor to
cause such trade  fixtures,  furnishings  and equipment  and all other  personal
property to be assessed and billed separately from the property of the Landlord.
If any of Tenant's said  personal  property  shall be assessed  with  Landlord's
property,  Tenant shall pay to Landlord the taxes  attributable to Tenant within
ten (10) days after receipt of a written  statement from Landlord  setting forth
the taxes applicable to Tenant's property.

11.      MAINTENANCE AND REPAIRS.

         (a)  Landlord's  Obligations.  Except  as  provided  in the  DAMAGE  OR
DESTRUCTION   section,  and  except  for  damage  caused  by  any  negligent  or
intentional act or omission of Tenant, Tenant's agents,  employees, or invitees,
Landlord at its sole cost and expense  shall keep in good  condition  and repair
the  foundations,  exterior walls,  and exterior roof of the Premises.  Landlord
shall also  maintain  the  unexposed  electrical,  plumbing  and sewage  systems
including,  without limitation,  those portions of the systems lying outside the
Premises; window frames, gutters and down spouts on the building, all sidewalks,
landscaping and other  improvements  that are a part of the Premises or of which
the  Premises  are a  part.  The  Landlord  shall  also  maintain  the  heating,
ventilating and air-conditioning systems servicing the Premises.  Landlord shall
have  thirty  (30) days after  notice  from  Tenant to  commence  to perform its
obligations  under this  Section,  and shall  thereafter  diligently  proceed to
complete such  performance,  except that Landlord shall perform its  obligations
immediately  if the  nature  of the  problem  presents  a  hazard  or  emergency
situation. If Landlord fails to perform Landlord's obligations as stated herein,
Tenant may at its  option  (but  shall not be  required  to) after ten (10) days
prior written notice to Landlord,  cure such failure,  and the reasonable  costs
thereof  together  with  interest  thereon at the rate of ten percent  (10%) per
annum may be deducted by Tenant  from the next  payments of rent and  additional
rent payable hereunder.
         (b) Tenant's  Obligations.  Subject to the provisions of  Sub-paragraph
(a) above and the DAMAGE OR  DESTRUCTION  section,  Tenant at Tenant's sole cost
and expense  shall keep in good order,  condition  and repair the  Premises  and
every  part  thereof,  including,  without  limitation,  all  Tenant's  personal

the rate of ten  (10%)  percent  per  annum  shall  become  due and  payable  as
additional rental to Landlord together with Tenant's next rental installment.

12.      ALTERATIONS AND ADDITIONS.

         (a) Tenant agrees that  no tenant improvements are necessary and Tenant
hereby accepts the Premises on an as is basis.
         (b) Tenant shall not,  without the  Landlord's  prior written  consent,
make any alterations,  improvements or additions in or about the Premises except
for non-structural work. As a condition to giving any such consent, the Landlord
may  reserve  the right to require  the  Tenant to remove any such  alterations,
improvements,  or additions at the  expiration  of the term,  and to restore the
Premises to their prior  condition  by giving  Tenant  thirty (30) days  written
notice prior to the  expiration  of the term that  Landlord  requires  Tenant to
remove any such  alterations,  improvements or additions that Tenant has made to
the Premises.  If Landlord so elects,  Tenant at its sole cost shall restore the
Premises to the condition designated by Landlord in its election before the last
day of the term of the Lease.
         Before commencing any work relating to the alterations,  additions,  or
improvements affecting the Premises,  Tenant shall notify Landlord in writing of
the expected date of the commencement of such work so that Landlord can post and
record the appropriate  notices of  non-responsibility  to protect Landlord from
any  mechanic's  liens,  materialman  liens,  or any other liens.  In any event,
Tenant shall pay, when due, all claims for labor and  materials  furnished to or
for Tenant at or for use in the Premises. Tenant shall not permit any mechanic's
liens or materialman's  liens to be levied against the Premises for any labor or
material  furnished  to Tenant or  claimed to have been  furnished  to Tenant or
Tenant's  agents  or  contractors  in  connection  with  work  of any  character
performed  or  claimed  to have  been  performed  on the  Premises  by or at the
direction of Tenant.  Tenant shall have the right to protest the validity of any
such lien if,  onwithin  thirty  (30) days  after  demand  by  Landlord,  Tenant
procures and records a lien release bond meeting the  requirements  of Minnesota
law and shall  provide for the payment of any sum that the  claimant may recover
on the  claim  (together  with  the  costs of suit,  if it is  recovered  in the
action).
         Unless the Landlord  requires  their  removal as set forth  above,  all
alterations,  improvements  or  additions  which are made on the Premises by the
Tenant  shall  become  the  property  of the  Landlord  and  remain  upon and be
surrendered with the Premises at the expiration of the term. Notwithstanding the
provisions of this paragraph, Tenant's trade fixtures, furniture,  equipment and
other  machinery,  other than that which is affixed to the  Premises  so that it
cannot be removed without material or structural  damage to the Premises,  shall
remain the property of the Tenant and removed by Tenant at the expiration of the
term of this Lease.

13.      INSURANCE; INDEMNITY.

         (a)      Fire Insurance.
                  Landlord  at its cost shall  maintain  during the term of this
Lease on the  Premises  a policy  or  policies  of  standard  fire and  extended
coverage  insurance  to the  extent of at least  eighty  (80%)  percent  of full
replacement value thereof.
                  Tenant  at its cost  shall  maintain  during  the term of this
Lease on all its personal property, Tenant's improvements, and alterations in or
about the Premises,  a policy of standard fire and extended coverage  insurance,
with vandalism and malicious  mischief  endorsements to the extent of their full
replacement value. The proceeds from any such policy shall be used by Tenant for
the replacement of personal property or the restoration of Tenant's improvements
or alterations.
         (b)      Liability Insurance.
                  Tenant at its sole cost and expense shall maintain  during the
term of this Lease public  liability and property damage insurance with a single
combined liability limit of not less than two million  ($2,000,000.00)  dollars,
and property damage limits of not less than five hundred thousand  ($500,000.00)
dollars,   insuring   against  all  liability  of  Tenant  and  its   authorized
representatives  arising out of and in connection with Tenant's use or occupancy
of the Premises.  Both public liability  insurance and property damage insurance
shall insure performance by Tenant of the indemnity  provisions in Sub-paragraph
(d)  below,  but the limits of such  insurance  shall  not,  however,  limit the
liability  of Tenant  hereunder.  Both  Landlord  and  Tenant  shall be named as
additional   insureds,   and  the   policies   shall   contain   cross-liability
endorsements. All public liability, property damage and other casualty insurance
policies shall be written as primary policies, not contributing with, and not as
excess to coverage which Landlord may carry.  Prior to occupancy and thereafter,
within at least fifteen (15) days of the expiration of any such policies, Tenant
agrees to deliver to Landlord,  certificates evidencing such insurance, provided
said certificates  contain an endorsement  stating that such insurance cannot be
modified or canceled,  nor the amount thereof  reduced,  except upon thirty (30)
days prior  written  notice to  Landlord.  If Tenant  shall fail to procure  and
maintain such  insurance the Landlord may, but shall not be required to, procure
and maintain same at the expense of Tenant and the cost  thereof,  together with
interest  thereon at the rate of ten (10%)  percent per annum,  shall become due
and payable as additional  rental to Landlord together with Tenant's next rental
installment.
         (c)      Waiver of Subrogation.
                  Tenant and Landlord each waives any and all rights of recovery
against  the  other,   or  against  the   officers,   employees,   agents,   and
representatives of the other, for loss of or damage to such waiving party or its
property or the property of others under its control,  where such loss or damage
is insured against under any insurance  policy in force at the time of such loss
or damage or is insurable  under the broad form Special  Cause of Loss  building
and  personal  property  insurance  policy  customarily  used  in the  State  of
Minnesota. Each party shall cause each insurance policy obtained by it hereunder
to provide  that the  insurance  company  waives all right of

                                       9



recovery by way of  subrogation  against  either  party in  connection  with any
damage covered by any such policy.
         (d)      Hold Harmless.
                  Tenant shall  indemnify  and hold  Landlord  harmless from and
against  any and all  claims  arising  from  Tenant's  use or  occupancy  of the
Premises or from the  conduct of its  business or from any  activity,  work,  or
things  which may be  permitted  or suffered by Tenant in or about the  Premises
including all damage, costs,  attorney's fees, expenses and liabilities incurred
in the defense of any claim or action or proceeding  arising  therefrom.  Except
for Landlord's willful or negligent  conduct,  Tenant hereby assumes all risk of
damage to property or injury to person in or about the Premises  from any cause,
and Tenant hereby waives all claims in respect thereof against Landlord.
         (e)      Exemption of Landlord from Liability.
                  Except for  Landlord's  willful or negligent  conduct,  Tenant
hereby  agrees  that  Landlord  shall not be liable for any  injury to  Tenant's
business  or loss  of  income  therefrom  or for  damage  to the  goods,  wares,
merchandise,  or  other  property  of  Tenant,  Tenant's  employees,   invitees,
customers or any other person in or about the  Premises,  nor shall  Landlord be
liable  for  injury  to  the  person  of  Tenant,  Tenant's  employees,  agents,
contractors,  or invitees, whether such damage or injury is caused by or results
from  fire,  steam,  electricity,  gas,  water  or rain,  or from the  breakage,
leakage,  obstruction or other defects of pipes, sprinklers,  wires, appliances,
plumbing,  air-conditioning,  or  lighting  fixtures,  or from any other  cause,
whether such damage  results from  conditions  arising upon the Premises or upon
other  portions of the building in which the  Premises  are a part,  or from any
other sources or places.  Landlord shall not be liable to Tenant for any damages
arising from any act or neglect of any other tenant,  if any, of the building in
which the Premises are located.

14.      DAMAGE OR DESTRUCTION.

         (a)      Damage - Insured.
                  If,  during the term of this Lease,  the  Premises  and/or the
building and other improvements in which the Premises are located are totally or
partially destroyed rendering the Premises totally or partially  inaccessible or
unusable,  and such damage or destruction was caused by a casualty covered under
an insurance policy required to be maintained hereunder,  Landlord shall restore
the Premises  and/or the building and other  improvements  in which the Premises
are located into  substantially  the same  condition as they were in immediately
before such damage or  destruction,  provided that the  restoration  can be made
under the  existing  laws and can be completed  within one hundred  twenty (120)
working days after the date of such  destruction or damage.  Such destruction or
damage shall not terminate this Lease.
                  If the restoration cannot be made in said 120 day period, then
within fifteen (15) days after the parties hereto determine that the restoration
cannot be made in the time stated in this  paragraph  but,  in any event  within
thirty (30) days of such damage or destruction,  Tenant may terminate this 

                                       10



Lease  immediately  by giving  notice to  Landlord  and the Lease will be deemed
canceled  as of the date of such  damage  or  destruction.  If  Tenant  fails to
terminate this Lease and the  restoration is permitted  under the existing laws,
Landlord, at its option, may terminate this Lease or restore the Premises and/or
any other  improvements  in which the Premises  are located  within a reasonable
time and this Lease shall  continue in full force and  effect.  If the  existing
laws do not  permit  the  restoration,  either  party can  terminate  this Lease
immediately by giving notice to the other party.
                  Notwithstanding the above, if the Tenant is the insuring party
and if the insurance  proceeds received by Landlord are not sufficient to effect
such  repair,  Landlord  shall give  notice to Tenant of the amount  required in
addition  to the  insurance  proceeds  to effect  such  repair.  Tenant  may, at
Tenant's  option,  contribute  the  required  amount,  but upon failure to do so
within thirty (30) days following such notice,  Landlord's sole remedy shall be,
at  Landlord's  option and with no liability to Tenant,  to cancel and terminate
this Lease.  If Tenant  shall  contribute  such  amount to Landlord  within said
thirty (30) day period,  Landlord  shall make such repairs as soon as reasonably
possible and this Lease shall continue in full force and effect. Tenant shall in
no event have any right to reimbursement for any amount so contributed.
         (b)      Damage - Uninsured.
                  In the event that the  Premises  are damaged or destroyed by a
casualty which is not covered by the fire and extended coverage  insurance which
is required to be carried by the party  designated in Article 11(a) above,  then
Landlord  shall restore the same;  provided that if the damage or destruction is
to an extent greater than ten (10%) percent of the then  replacement cost of the
improvements on the Premises (exclusive of Tenant's trade fixtures and equipment
and  exclusive of  foundations  and  footings),  then  Landlord may elect not to
restore and to terminate this Lease. Landlord must give to Tenant written notice
of its  intention  not to restore  within thirty (30) days from the date of such
damage  or  destruction  and,  if not  given,  Landlord  shall be deemed to have
elected  to  restore  and in such  event  shall  repair  any  damage  as soon as
reasonably  possible.  In the event that Landlord  elects to give such notice of
Landlord's  intention to cancel and terminate this Lease,  Tenant shall have the
right, within ten (10) days after receipt of such notice, to give written notice
to  Landlord of Tenant's  intention  to repair such damage at Tenant's  expense,
without  reimbursement from Landlord, in which event the Lease shall continue in
full force and effect and Tenant  shall  proceed to make such repairs as soon as
reasonably possible.  If the Tenant does not give such notice within such 10 day
period,  this Lease shall be canceled and be deemed terminated as of the date of
the occurrence of such damage or destruction.
         (c)      Damage Near the End of the Term.
                  If the Premises are totally or partially  destroyed or damaged
during the last twelve (12) months of the term of this Lease,  Landlord  may, at
Landlord's  option,  cancel and terminate this Lease as of the date of the cause
of such damage by given written notice to Tenant of Landlord's election to do so
within  30 days  after  the date of the  occurrence  of such  damage;  provided,
however,  that, if the damage or destruction  occurs within the last twelve (12)
months of the term and if within fifteen (15) days after the date of such 

                                       11



damage or  destruction  Tenant  exercises any option to extend the term provided
herein, Landlord shall restore the Premises if obligated to do so as provided in
subparagraph (a) or (b) above.
         (d)      Abatement of Rent.
                  If the Premises are partially or totally  destroyed or damaged
and Landlord or Tenant  repairs or restores them  pursuant to the  provisions of
this  Article,  the rent and  additional  rent payable  hereunder for the period
during which such damage,  repair or  restoration  continues  shall be abated in
proportion  to the degree to which  Tenant's  reasonable  use of the Premises is
impaired.  Except for the abatement of rent, if any,  Tenant shall have no claim
against  Landlord  for any  damages  suffered  by  reason  of any  such  damage,
destruction, repair or restoration.
         (e)      Trade Fixtures and Equipment.
                  If Landlord  is required or elects to restore the  Premises as
provided in this  Article,  Landlord  shall not be required to restore  Tenant's
improvements,  trade  fixtures,  equipment or alterations  made by Tenant,  such
excluded items being the sole responsibility of Tenant to restore hereunder.

15.      PARKING.

         At no additional  cost,  Landlord  agrees to maintain  (including  snow
removal when  appropriate)  and allow Tenant to use a general  parking area. The
parking area is designated on Exhibit A. Tenant's right to use said parking area
is subject to the public's  parking  rights,  as so  designated by Landlord from
time to time to the City of Arden Hills, for the adjacent park.

16.      CONDEMNATION.

         If the  Premises  or any  portion  thereof  are  taken by the  power of
eminent  domain,  or sold by Landlord under the threat of exercise of said power
(all of which  is  herein  referred  to as  "condemnation"),  this  Lease  shall
terminate as to the part so taken as of the date the condemning  authority takes
title or possession,  whichever  occurs first. If more than twenty (20%) percent
of the floor area of any  buildings on the  Premises,  or more than twenty (20%)
percent of the land area of the Premises not covered with buildings, is taken by
condemnation,  either Landlord or Tenant may terminate this Lease as of the date
the condemning  authority takes possession by notice in writing of such election
within twenty (20) days after Landlord shall have notified Tenant of such taking
or, in the  absence  of such  notice,  then  within  twenty  (20) days after the
condemning authority shall have taken possession. Notwithstanding the foregoing,
if such  partial  materially  interferes  with  Tenant's use or occupancy of the
Premises, Tenant shall have the right to terminate the Lease.
         If this  Lease is not  terminated  by  either  Landlord  or  Tenant  as
provided  hereinabove,  then it shall  remain in full force and effect as to the
portion of the Premises remaining,  provided that the rental shall be reduced in
proportion to the floor area of the buildings taken within the Premises as bears
to the total floor area of all buildings  located on the Premises.  In the 

                                       12



event this Lease is not so terminated,  then Landlord  agrees at Landlord's sole
cost and expense,  to as soon as reasonably  possible  restore the Premises to a
complete   unit  of  like  quality  and   character  as  existed  prior  to  the
condemnation.
         All awards for the taking of any part of the  Premises  or any  payment
made under the threat of the  exercise of the power of eminent  domain  shall be
the property of the Landlord, whether made as compensation for the diminution of
the value of the leasehold or for the taking of the fee or as severance damages;
provided,  however,  that  Tenant  shall be entitled to any award for loss of or
damage to Tenant's trade fixtures and removable personal property, good will and
going-concern value.
         Rent  shall be abated or reduced  during  the  period  from the date of
taking  until  the  completion  of  restoration  by  Landlord,   but  all  other
obligations  of Tenant  under this Lease shall  remain in full force and effect.
The abatement or reduction of the rent shall be based on the extent to which the
restoration interferes with Tenant's use of the Premises.

17.      ASSIGNMENT AND SUBLETTING.

         Landlord's  rights under this Lease may be assigned or conveyed without
notice to Tenant,  but such assignment or conveyance  shall not relieve Landlord
of any of its  obligations  hereunder  and shall not be valid as to Tenant until
ten (10) days after Tenant  receives  written notice  thereof.  Tenant shall not
voluntarily  or by  operation  of law assign,  transfer,  sublet,  mortgage,  or
otherwise  transfer  or encumber  all or any part of  Tenant's  interest in this
Lease or in the Premises without  Landlord's prior written consent which consent
shall  not  be  unreasonably  withheld.  Any  attempted  assignment,   transfer,
mortgage,  encumbrance,  or  subletting  without such consent  shall be void and
shall constitute a breach of this Lease. Tenant's extension rights in this Lease
Agreement  are not  assignable  except  in  connection  with a sale of Tenant or
Tenant's assets.  Regardless of Landlord's  consent, no subletting or assignment
shall release  Tenant of Tenant's  obligation to pay the rent and to perform all
other  obligations  to be  performed  by Tenant  hereunder  for the term of this
Lease.  The  acceptance  of rent by Landlord  from any other person shall not be
deemed a waiver by Landlord of any provision  hereof.  Consent to one assignment
or  subletting  shall not be deemed  consent  to any  subsequent  assignment  or
subletting.

18.      DEFAULT

         (a)      Events of Default.
                  The  occurrence  of any one or more  of the  following  events
shall constitute a default and breach of this Lease by Tenant:
                  (1) Failure to pay rent when due, if the failure continues for
five (5) days after written notice has been given to Tenant.
                  (2) Tenant shall be  considered in default under the Lease for
the  abandonment  of the  Premises  if the  Premises  are not kept in an orderly
condition  and the rent is not paid in  accordance  with the  terms of the Lease
within the grace periods provided in paragraphs (1) and (3) of this section.

                                       13



                  (3)  Failure to perform any other  provision  of this Lease if
the failure to perform is not cured within thirty (30) days after written notice
thereof has been given to Tenant by Landlord.  If the default cannot  reasonably
be cured  within said thirty  (30) day  period,  Tenant  shall not be in default
under this Lease if Tenant  commences to cure the default within the thirty (30)
day period and diligently prosecutes the same to completion.
                  (4) The making by Tenant of any general assignment, or general
arrangement  for the benefit of creditors;  the filing by or against Tenant of a
petition to have Tenant adjudged a bankrupt or a petition for  reorganization or
arrangement  under any law relating to  bankruptcy  unless the same is dismissed
within  sixty (60)  days;  the  appointment  of a trustee  or  receiver  to take
possession of substantially all of Tenant's assets located at the Premises or of
Tenant's  interest  in the Lease,  where  possession  is not  restored to Tenant
within thirty (30) days; or the attachment,  execution or other judicial seizure
of  substantially  all of Tenant's assets located at the Premises or of Tenant's
interest in the Lease,  where such seizure is not discharged  within thirty (30)
days.
         Notices given under this  paragraph  shall specify the alleged  default
and the applicable  lease  provisions,  and shall demand that Tenant perform the
provisions  of this Lease or pay the rent that is in arrears as the case may be,
within  the  applicable  period  of  time.  No such  notice  shall  be  deemed a
forfeiture  or a  termination  of this Lease  unless  Landlord  so elects in the
notice.
         (b)      Landlord's Remedies.
                  The  Landlord  shall  have the  following  remedies  if Tenant
commits a default  under this Lease.  These  remedies are not  exclusive but are
cumulative and in addition to any remedies now or hereafter allowed by law.
         Landlord  can  continue  this Lease in full force and  effect,  and the
Lease will continue in effect so long as Landlord  does not  terminate  Tenant's
right to possession,  and the Landlord shall have the right to collect rent when
due.  During  the  period  that  Tenant is in  default,  Landlord  can enter the
Premises  and relet them,  or any part of them,  to third  parties for  Tenant's
account.  Tenant shall be liable  immediately  to the Landlord for all costs the
Landlord  incurs in  reletting  the  Premises,  including,  without  limitation,
brokers'  commissions,  expenses  of  remodeling  the  Premises  required by the
reletting,  and like costs. Reletting can be for a period shorter or longer than
the  remaining  term of this Lease.  Tenant  shall pay to Landlord  the rent due
under this Lease on the dates the rent is due, less the rent  Landlord  receives
from any reletting. No act by Landlord allowed by this paragraph shall terminate
this Lease unless  Landlord  notifies  Tenant that Landlord  elects to terminate
this  Lease.  After  Tenant's  default  and  for so  long  as  Landlord  has not
terminated  Tenant's  right to  possession of the  Premises,  if Tenant  obtains
Landlord's consent, Tenant shall have the right to assume or sublet its interest
in the Lease,  but  Tenant  shall not be  released  from  liability.  Landlord's
consent to the  proposed  assignment  or  subletting  shall not be  unreasonably
withheld.
         If Landlord elects to relet the Premises as provided in this paragraph,
any rent that  Landlord  receives from such  reletting  shall apply first to the
payment of any indebtedness from Tenant to Landlord other than the rent 

                                       14



due from Tenant to  Landlord;  secondly,  to all costs,  including  maintenance,
incurred by Landlord in such  reletting;  and third,  to any rent due and unpaid
under this Lease.  After  deducting the payments  referred to in this paragraph,
any sum remaining from the rent Landlord  receives from such reletting  shall be
held by Landlord and applied in payment of future rent as rent becomes due under
this Lease.  In no event shall tenant be entitled to any excess rent received by
Landlord.  If, on the date rent is due under this, Lease, the rent received from
the  reletting  is less  than the rent due on that  date,  Tenant  shall  pay to
Landlord,  in  addition  to  the  remaining  rent  due,  all  costs,   including
maintenance,  that Landlord  shall have incurred in reletting  that remain after
applying the rent received from the reletting as provided in this paragraph.
         If Tenant is in default and such default is  continuing,  Landlord can,
at its option,  terminate  Tenant's  right to  possession of the Premises at any
time.  No act by  Landlord  other than  giving  written  notice to Tenant  shall
terminate this Lease. Acts of maintenance or efforts to relet the Premises shall
not constitute a termination  of Tenant's  right to possession.  In the event of
such termination, Landlord has the right to recover from Tenant:
         (1) The unpaid rent that had been earned at the time of the termination
of this Lease;  
         (2) The present value (using a discount factor  equal to treasury rates
for a  comparable  period)  of the amount of rent that would have been due under
the  lease  from the time of  termination  to the end of the term of this  Lease
Agreement in excess of the Fair Market Rental Value of the Premises;
         (3) Notwithstanding  Article 18(b)(2) above,  Landlord,  at its option,
may defer  terminating  the Lease  until  such  time as  Landlord  has relet the
Premises.  In such case,  Landlord  has the right to recover from the Tenant the
amount of rent  that  would  have been due under the Lease  from the time of the
determination less the proceeds attributable to the reletting of the Premises;
         (4) Any   other  amount, including court costs, necessary to compensate
Landlord for all detriment proximately caused by Tenant's default;
         (5) Any damage or loss of rent  sustained  by Landlord may be recovered
by Landlord,  at Landlord's  option, at the time of the reletting or in separate
actions  from time to time as said  damage  shall have been  ascertained  or, at
Landlord's  option,  may be deferred  until the expiration of the Term (in which
event Tenant  hereby agrees that the cause of action shall not be deemed to have
accrued until the date of expiration of the Term).  The provisions  contained in
this  Article  18(b)(5)  shall be in  addition  to and  shall  not  prevent  the
enforcement  of any claim  Landlord  may have  against  Tenant for  anticipatory
breach of the unexpired term of this Lease.
         Landlord at any time after  Tenant  commits a default,  after notice to
Tenant can cure the default at  Tenant's  cost and  expense.  If Landlord at any
time, by reason of Tenant's default,  pays any sum or does any act that requires
the payment of any sum, the sum paid by Landlord shall be due  immediately  from
Tenant  to  Landlord  at the time the sum is paid,  and if paid at a later  date
shall bear  interest at the maximum  rate an  individual  is permitted by law to
charge from the date the sum is paid by Landlord until

                                       15



Landlord is reimbursed by Tenant. The sum, together with interest thereon, shall
be considered additional rent.

19.      SIGNS.

         Tenant  shall not have the right to place,  construct  or maintain  any
sign,  advertisement,  awning,  banner,  or other  exterior  decorations  on the
building or property of the  Landlord or other  improvements  that are a part of
the  Premises  (except  those  existing on the date hereof)  without  Landlord's
prior,  written consent. Any signs that are placed on the Landlord's property or
the Premises  shall be at the sole expense of Tenant and shall  conform with all
applicable  zoning laws.  Tenant agrees to maintain its signs in good repair, to
remove  its signs at the end of the term or any  intended  term,  repairing  any
damage caused by such removal, and to hold Landlord harmless from any loss, cost
or damages  resulting  from the erection,  existence,  maintenance or removal of
Tenant's signs.

20.      SUBORDINATION.

         This Lease,  at Landlord's  option,  shall be subordinate to any ground
lease,  mortgage,  deed of trust, or any other hypothecation for security now or
hereafter  placed upon the real property of which the Premises are a part and to
any  and  all  advances  made  on the  security  thereof  and  to  all  renewal,
modifications,  and extensions thereof.  Notwithstanding any such subordination,
Tenant's  right to quiet  possession of the Premises and other rights under this
Lease shall not be disturbed and shall be recognized if Tenant is not in default
and so long as Tenant  shall pay the rent and  observe and perform all the other
provisions of this Lease within the periods of grace provided for herein, unless
this Lease is  otherwise  terminated  pursuant to its terms.  If any  mortgagee,
trustee,  or ground  lessor  shall elect to have this Lease prior to the lien of
its mortgage or deed of trust or ground  lease,  and shall give  written  notice
thereof to Tenant,  this Lease shall be deemed prior to such  mortgage,  deed of
trust or ground lease, whether this Lease is dated prior to or subsequent to the
date of such mortgage,  deed of trust or ground lease,  or the date of recording
thereof.  Tenant  agrees to  execute  any  documents  required  to  effect  such
subordination  or to make this Lease prior to the lien of any mortgage,  deed of
trust, or ground lease, as the case may be, and failing to do so within ten (10)
days after  written  demand from  Landlord  does  hereby  make,  constitute  and
irrevocably  appoint Landlord as Tenant's attorney in fact and in Tenant's name,
place and stead to do so.

21.      SURRENDER.

         On the last  day of the  term  hereof,  or on any  sooner  termination,
Tenant shall surrender the Premises to Landlord in good condition,  broom clean,
ordinary  wear and tear and casualty  damage  excepted.  Tenant shall repair any
damage to the  Premises  occasioned  by its use  thereof,  or by the  removal of
Tenant's trade  fixtures,  furnishings  and equipment which repair shall include
the patching and filling of holes and repair of structural damage.  

                                       16



Tenant shall  remove all of its  personal  property and fixtures on the Premises
prior to the  expiration  of the term of this Lease and if  required by Landlord
pursuant to the  ALTERATIONS  AND  ADDITIONS  section  above,  any  alterations,
improvements  or additions  made by Tenant to the  Premises.  If Tenant fails to
surrender the Premises to Landlord on the expiration of the Lease as required by
this paragraph,  Tenant shall hold Landlord  harmless from all damages resulting
from Tenant's  failure to vacate the Premises,  including,  without  limitation,
claims  made  by any  succeeding  tenant  resulting  from  Tenant's  failure  to
surrender the Premises.

22.      HOLDING OVER.

         If the Tenant,  with the Landlord's  consent,  remains in possession of
the Premises after the expiration or termination of the term of this Lease, such
possession  by Tenant shall be deemed to be a tenancy from  month-to-month  at a
rental of one hundred and fifty  percent  (150%) the amount of the last  monthly
rental plus all other charges payable hereunder, upon all the provisions of this
Lease applicable to  month-to-month  tenancy.  If Landlord's  consent to holding
over is not given, Tenant shall become a tenant-at-sufferance.

23.      BINDING ON SUCCESSORS AND ASSIGNS.

         The terms, conditions and covenants of this Lease shall be binding upon
and shall  inure to the  benefit of each of the  parties  hereto,  their  heirs,
personal representatives, successors and permitted assigns.

24.      NOTICES.

         Whenever under this Lease a provision is made for any demand, notice or
declaration of any kind, it shall be in writing and served either  personally or
sent by registered or certified United States mail,  postage prepaid,  addressed

arbitration  concerning  this  Lease,  the  Premises,  or the  building or other
improvements in which the Premises are located, by reason of any act or omission
of the other party or its authorized  representatives,  and not by reason of any
act or omission of the party that becomes a party to that  litigation or any act

of any other provision hereof or of any subsequent  breach by Tenant of the same
or any other provision.  Landlord's  consent to or approval of any act shall not
be deemed to render  unnecessary  the  obtaining  of  Landlord's  consent  to or
approval of any  subsequent  act by Tenant.  The acceptance of rent hereunder by
Landlord  shall  not be a  waiver  of any  preceding  breach  by  Tenant  of any
provision hereof, other than the failure of Tenant to pay the

particular  rent  so  accepted,  regardless  of  Landlord's  knowledge  of  such
preceding breach at the time of its acceptance of such rent.

         This Lease  contains all  agreements of the parties with respect to any

advance, and the amount of any security deposit or prepaid rent, if any, as well
as  acknowledging  that there are not, to that  party's  knowledge,  any uncured
defaults on the part of the other party,  or specifying  such defaults,  if any,
which are claimed. Failure to deliver such a certificate within the ten (10) day
period shall be conclusive  upon the party failing to deliver the certificate to
the benefit of the party  requesting the certificate  that this Lease is in full
force and effect, that there are no uncured defaults hereunder, and has not been
modified except as may be represented by the party requesting the certificate.

34.      ACCEPTANCE OF PREMISES.

Premises by Tenant  causes the  Landlord  to be  required  under the ADA to make
additional  modifications  or  alterations  to the  Premises or any of the other
areas of the building or its entrances and parking areas,  then Tenant shall pay
the  cost  of  such  additional  modifications  or  alterations  subject  to the
provisions of Section 9. Landlord  represents  and warrants that, to the best of

Landlord's  knowledge  that,  except  for those  areas  listed on Exhibit D, the

or  promulgated.  Tenant  shall fully  comply at its sole expense with all laws,
statutes,  ordinances and governmental rules, regulations or requirements now in

the  extent  that  if such  cleanup,  remediation,  removal  or  restoration  is
attributable to Tenant's  actions or failure to act. In such case,  tenant shall
be fully  responsible  for  compliance  and shall  indemnify  and hold  landlord
harmless for any costs, expenses or damages attributable thereto.

38.      ADDENDUM.

         Any addendum or exhibit  attached hereto and either signed or initialed
by the parties shall be deemed a part hereof and shall supersede any conflicting
terms or provisions contained in this Lease.

         Landlord and Tenant each  represent and warrant to the other that it is
not  aware of any  brokers  or  finders  who may  claim a fee or  commission  in

the  transactions  contemplated by this Agreement  arise,  then Tenant agrees to
indemnify, protect, hold harmless and defend Landlord (with counsel satisfactory
to  Landlord)  from and  against any such claims if they shall be based upon any
statement,  representation  or agreement made by Tenant,  and Landlord agrees to

labor disputes, civil commotion, war, war-like operations,  invasion, rebellion,
hostilities,  military or usurped power, sabotage,  governmental  regulations or
controls,  fire or other casualty,  inability to obtain any material services or

performance of obligations hereunder provided:
         (a) nothing  contained  in this  Paragraph  or  elsewhere in this Lease
shall be deemed to excuse  or  permit  any delay in the  payment  of any sums of
money required  hereunder,  or any delay in the cure of any default which may be
cured by the payment of money;

Commencement  Date of this Lease Agreement.  If Tenant is in arrears in its Rent
payment or other financial obligations to Landlord, subject Security Deposit may
be applied to current Rent or such other financial  obligations owed to Landlord
and Tenant will immediately replenish the Security Deposit in full. After August
1,  1997,  if Tenant is not in  default,  is  current  in its Rent  payments  to
Landlord  and has met its full  financial  obligations,  within  sixty (60) days
after receipt of a written request from Tenant,  Landlord will issue a credit of
subject Security Deposit to Tenant's monthly rental payment due Landlord.

         Not less than sixty (60) days prior to accepting  any offer to purchase
or making any offer to sell the  Premises or the  property of which the Premises
are a part,  Landlord  shall notify  Tenant in writing and advise  Tenant of the
price at which Landlord intends to list such property or otherwise is willing to
accept for sale of such property. Landlord agrees to entertain in good faith any
purchase  offer made by Tenant for such property  after giving such notice,  but
this  provision  shall  not be  deemed  to be an  agreement  for the sale of any
property on any terms.

The parties hereto have executed this Lease on the date first above written.
