<PAGE>


written consent of the Landlord.  Tenant shall not sublease to existing  tenants

     16. BREACH.

          a. Re-entry.  If default be made by the Tenant in the payment of rent,
or any part  thereof,  or if the Tenant  shall fail to observe or perform any of
the conditions or agreements of this Lease,  and such default shall continue for

happen,  it shall be lawful for the Landlord,  at its election,  with or without
legal  proceedings,  using such force as may be necessary and without notice, to
re-enter  and  take   possession   of  the  Demised   Premises,   including  all
improvements,  fixtures  and  equipment  located  at,  in, or about the  Demised
Premises and take,  operate, or relet same, in whole or in part, for the account
of Lessee at such rental, on such conditions,  and to such tenant(s) as Landlord
in good faith may deem  proper.  Landlord  shall  receive  all  proceeds  and/or
rentals  accruing from such operation or reletting and shall apply such proceeds
and/or  rentals,  first,  to the payment of all costs and  expenses  incurred by
Landlord in  obtaining  possession  and in the  operation  or  reletting  of the
Demised  Premises,  fixtures,  or  equipment,  including,  but not  limited  to,
reasonable   attorney's  fees,   commissions,   and  collection  fees,  and  any
alterations  or repairs  reasonably  necessary to enable  Landlord to operate or
relet the Demised Premises,  fixtures, or equipment;  and second, to the payment
of all such amounts due or becoming due from Tenant under the provisions of this
Lease.

           b. Insolvency.  If Tenant shall be declared insolvent or bankrupt, or
if any  assignment  of  Tenant's  property  shall  be made  for the  benefit  of
creditors or otherwise, or if Tenant's leasehold interest herein shall be levied
upon under execution,  or seized by virtue of any writ of any Court of law, or a
Trustee in  Bankruptcy  or a Receiver be  appointed  for the  property of Tenant
("involuntary  breach"),  whether  under  the  operation  of  State  or  Federal
statutes,  then and in any such case, Landlord may, at its option,  immediately,
with or without notice (notice being expressly waived), terminate this Lease and
immediately  retake  possession  of said  premises,  using  such force as may be
necessary,  without being guilty of any manner of trespass or forcible  entry or
detainer,  and without  the same working any  forfeiture of the  obligations  of
Tenant  hereunder.  In such event the Lessor  shall be deemed to have a provable
claim in bankruptcy or receivership in an amount equal to: (1) the  then-accrued
and  unpaid  rent,  plus (2) an  amount  equal  to the sum of the last  nine (9)


                                       8
<PAGE>


monthly  installments of the rental provided for herein, which sum is fixed, not
as a penalty,  but as  liquidated  damages by the  parties  hereto  because  the
actual damages incurred by Landlord as a result of the involuntary  breach would
be difficult to ascertain.

          c.  Repossession or Reletting Not a Termination.  Landlord's  Right To
Terminate Not Forfeited. No re-entry,  repossession,  operation, or relettinq of
the Demised Premises or the fixtures and equipment therein shall be construed as
an  election  by Landlord to  terminate  this Lease  Agreement  unless a written
notice of such  intention  is given by Landlord to Tenant.  Notwithstanding  any
operation or reletting  without  terminating this Lease Agreement,  Landlord may
at any time thereafter elect to terminate said Lease Agreement.

          d. Tenant's Obligation to Pay Deficiencies.  In the event the proceeds
or rentals  received by Landlord  pursuant to this paragraph are insufficient to
pay all costs and expenses incurred by Landlord and all amounts due and becoming
due under this Lease  Agreement,  Tenant shall pay to Landlord,  on demand,  any
such deficiency as may from time to time occur or exist.

          e. Landlord's  Right to Perform  Tenant's Duties at Tenant's  Expense.
Notwithstanding  any notice provisions  contained in this Lease Agreement to the
contrary,  if, in the judgment of Landlord,  the  continuance  of any default by
Tenant,  other than default in the payment of money,  for the full notice period
otherwise provided herein will jeopardize the Demised Premises, the Building, or
the rights of Landlord or other tenants,  Landlord may, without notice, elect to
perform or cure, at the expense of Tenant, those acts in respect of which Tenant
is in  default  and Tenant  shall,  within  ten (10) days  following  receipt of
written notice of same,  reimburse  Landlord for all costs and expenses incurred
by Landlord,  together  with  interest  thereon at the rate of eighteen  percent
(18%) per annum until paid in full.

          f.  Landlord's  Right to  Terminate  Lease.  In the event of  Tenant's
default as  provided in this  paragraph,  Landlord  may, at its option,  without
further notice,  terminate this Lease Agreement,  and may thereupon  immediately
reenter and take possession of the Demised Premises.

          g.  Landlord's  Right on  Termination  to Recover Amount Equal to Rent
Reserved.  If this Lease  Agreement is  terminated by Landlord on account of any
default by Tenant, Landlord shall be entitled to recover as damages from Tenant,
at the time of such  termination,  along with any and all other damages to which
it is entitled,  the excess,  if any, of the amount of rent provided  herein for
the  balance of the term  hereof over the then  reasonable  rental  value of the
Demised Premises for the same period.  It is agreed that the "reasonable  rental
value" shall be the amount of rental  which  Landlord can obtain as rent for the
remaining balance of the term.

seek all remedies  provided in this Lease  Agreement and by the  governing  law.

shall be  cumulative,  and the exercise of one right or remedy by Landlord shall
not impair its right to exercise any other right or remedy.

          i. Tenant's  Waiver of Claims Against  Landlord.  Tenant hereby waives
all claim or demand for damages that may be caused by Landlord's re-entering and
