landlord, or its agent, the said rent at the times and in the manner above
provided. In the event of the non-payment of said rent, or any installment
thereof, at the times and in the manner above provided, or if the tenant shall

month, or may hold the tenant in advance for the entire deficiency to be
realized during the term of the reletting. The tenant shall not be entitled to
any surplus accruing as a result of the reletting. The landlord is hereby

this lease, the tenant hereby waiving the benefit of all laws exempting property
from execution, levy and sale on distress or judgment. The tenant agrees to pay,
as additional rent, all reasonable attorney's fees and other reasonable expenses
incurred by the landlord in enforcing any of the obligations under this lease.

                  (a) If at any time prior to the date herein fixed as of the

other rights and remedies given by (c) hereby and by virtue of any other
provision herein or elsewhere in this lease contained or by virtue of any

statute or rule of law, may retain as liquidated damages any rent, security,
deposit of moneys received by them from tenant or others in behalf of tenant
upon the execution hereof.

<PAGE>

                  (b) If at the date fixed as the commencement of the term of
this lease or if at any time during the term hereby demised there shall be filed
by or against Tenant in any court pursuant to any statute either of the United

to secure a discharge thereof, or if tenant makes an assignment for the benefit
of creditors or petition for or enter into an arrangement this lease, at the
option of the landlord, exercised within a reasonable time after notice of the
happening of any one or more of such events, may be cancelled and terminated and
in which event neither tenant nor any person claiming through or under tenant by
virtue of any statute or of an order of any court shall be entitled to
possession or to remain in possession of the premises demised but shall
forthwith quit and surrender the premises, and landlord, in addition to the
other rights and remedies landlord has by virtue of any other provision herein
or elsewhere in this lease contained or by virtue of any statute or rule of law,
may retain as liquidated damages any rent, security, deposit or moneys received
by them from tenant or others in behalf of tenant.

                  (c) It is stipulated and agreed that in the event of the
termination of this lease pursuant to (a) or (b) landlord shall forthwith,

term demised and the then fair and reasonable rental value of the demised
premises for the same period. If such premises or any part thereof be re-let by
the landlord for the unexpired term of said lease or any part thereof, before

tribunal, the amount of rent reserved upon such re-letting shall be prima facie
to be the fair and reasonable rental value for the part or the whole of the
premises so re-let during the term of the re-letting. Nothing herein contained
shall limit or prejudice the right of the landlord to prove for and obtain as
liquidated damages by reason of such termination, an amount equal to the maximum
allowed by any statute or rule of law in effect at the time when, and governing
the proceedings, in which such damages are to be proved, whether or not such

to above.
