have assumed, subject to the limitations of this paragraph, all of the terms,
covenants and conditions in this Lease contained to be performed on the part of

contained in this Lease on the part of the Lessor shall, subject as aforesaid,
be binding on the Lessor, its successors and assigns, only during and in respect
of their respective successive periods of ownership.

(c)     PROVIDED that the Lessor shall have the right during the term of this

deposit, payment, court order or otherwise. The Lessee shall defend all suits to

default, breach or non-observance by the Lessee or the Lessor as the case may be
at any time or times in respect of any covenant, provision or condition
hereincontained or the acceptance of any Rent while any such default, breach or
non-observance exists shall not (any law, statutory or otherwise, to the
contrary notwithstanding) operate as a waiver of the Lessor's or lessee's as the
case may be, rights hereunder in respect of any continuing or subsequent
default, breach or non-observance,

<PAGE>

                                      -13-

nor so as to defeat or effect in any way the rights of the Lessor hereunder in
respect of any such continuing or subsequent default, breach or non-observance
and all rights and remedies herein contained of the Lessor or the Lessee shall
be deemed to be cumulative and not alternative and the taking of any proceeding
or step shall not preclude the taking of any other proceeding or step.

38.     INVALIDITY OF PARTICULAR PROVISIONS:

notice to Lessee specifying such default, or without notice if in the reasonable

to, perform the same for the account and at the expense (including reasonable
counsel fees) of Lessee and the amount of any payments made or reasonable
expenses incurred by Lessor for such purpose, with interest thereon at the rate
of Ten Percent (10%) per annum, shall become due and payable by Lessee as
additional Rent with the next or any subsequent instalment of Rent which shall
become due after such expenditure by Lessor: but any such expenditure by Lessor
shall not be deemed to waive or release Lessee's default or the right of Lessor
to take such action as may be permissible under the terms of this lease in the
event of such default. When no emergency exists, the provisions of this
Paragraph shall be inapplicable if, within thirty (30) days after such notice by
Lessor, Lessee shall have cured such default or shall have commenced and is
diligently proceeding to cure same.

(b)     If the Lessor shall default in any of the covenants or agreements herein
contained, to be kept by the Lessor and the Lessor shall not commence to cure
