reasonable discretion, increase or decrease from time to time during such
calendar year the amount initially so estimated for such calendar year, all by
giving the Tenant written notice thereof, provided in accordance with Lease
Section 19 accompanied by a schedule setting forth in reasonable detail the

any Rent then past due before being credited to Rent currently falling due. Any
such payment which is less than the amount of Rent then due shall constitute a
payment made on account thereof, the parties hereto hereby agreeing that the
Landlord's acceptance of such payment (whether or not with or accompanied by an
endorsement or statement that such lesser amount or the Landlord's acceptance

square feet.

8.4. Waiver of subrogation. If either party hereto is paid any proceeds under
any policy of insurance naming such party as an insured, on account of any loss
or damage, then such party hereby releases the other party hereto, to and only
to the extent of the amount of such proceeds, from any and all liability for
such loss or damage, notwithstanding that such loss, damage or liability may

subleases any or all of the Premises, and Landlord consents to such assignment
or sublease, Tenant shall furnish to Landlord as part of said consent request

necessary for the Landlord to act to cure such Event of Default without giving
such notice, or (ii) more than twice during any twelve (12) month period.

16.3.     Landord's rights on Event of Default.

16.3.1. On the occurrence of any Event of Default ,the Landord may subject to
the operation and effect of the provisions of subsection 16.2 take any or all of
the following actions:

(a)      reenter and repossess any or all of the Premises and any or all
improvements thereon and additions thereto; and/or

(b) terminate this Lease by giving written notice of such termination to the
Tenant, which termination shall be effective as of the date of such notice or
any later date therefor specified by the Landlord therein provided, {that
without limiting the generality of the foregoing provisions of this subparagraph
16.3. 1(c), the Landlord shall not be deemed to have accepted any abandonment or
surrender by the Tenant of any or all of the Premises or the Tenant's leasehold
estate under this Lease unless the Landlord has so advised the Tenant expressly
and in writing, regardless of whether the Landlord has reentered or relet any or
all of the Premises or exercised any or all of the Landlord's other rights under
the provisions of this Section or applicable law; and/or

(c) in the Landlord's own name but either (i) as agent for the Tenant, if this
Lease has not then been terminated, or (ii) on the Landlord's own behalf, if
this Lease has then been terminated, relet any or all of the Premises with or
without any additional premises, for any or all of the remainder of the Term or,
if this Lease has then been terminated, for any or all of the period which
would, but for such termination, have constituted the remainder of the Term or
for a period exceeding such remainder, on such terms and subject to such
conditions as are acceptable to the Landlord in its sole and absolute discretion
including, by way of example rather than of limitation, the alteration of any or
all of the Premises in any manner which, in the Landlord's judgment, is
necessary or desirable as a condition to or otherwise in connection with such
reletting, and the allowance of one or more concessions or "free-rent" or
reduced-rent periods, and collect and receive the rents therefor. Anything
contained in the provisions of this Lease or applicable law to the contrary
notwithstanding, (1) the Landlord shall not have any duty or obligation to
{relet any or all of the Premises as the result of any Event of Default, or any
liability to the Tenant or any other person for any failure to do so or to
<PAGE>

collect any rent or other sum due from any such reletting;

(ii) the Tenant shall have no right in or to any surplus which may be derived by
the Landlord from any such {reletting, in the event that the proceeds of such
{reletting exceed any Rent, installment thereof or other sum owed by
the Tenant to the Landlord hereunder; and, (iii) the Tenant's liability
hereunder shall not be diminished or affected by any such failure to relet or
the giving of any such initial or other concessions or "free-rent" or reduced
rent period in the event of any such reletting. In such event, the Tenant shall
pay to the Landlord, at the times and in the manner specified by the provisions
of Section 2, both (i) the installments of the Base Rent and any Additional Rent
accruing during such remainder or, if this Lease has then been terminated,
damages equaling the respective amounts of such installments of the Base Rent
and any Additional Rent which would have accrued during such remainder,
had this Lease not been terminated, less any monies received by the Landlord
with respect to such remainder from such reletting of any or all of the
Premises, plus {(ii) the cost to the Landlord of any such reletting (including,
by way
<PAGE>

of example rather than of limitation, any attorneys' fees, leasing or brokerage
commissions, repair or improvement expenses and the expense of any other actions
taken in connection with such reletting), plus (iii) any other sums for which
the Tenant is liable under the provisions of paragraph 16.3 and the Tenant
hereby waives any and all rights which it may have under applicable law, the
exercise of which would be inconsistent with the foregoing provisions

of this subparagraph 16.3.I(d); and/or

(d)       cure such Event of Default in any other manner; and/or

(e) pursue any combination of such remedies and/or any other right or remedy
available to the Landlord on account of such Event of Default under this Lease
and/or at law or in equity.

(f) collect entire amount of rent due for the remainder of the lease term at
time of default.

16.3.2. No such expiration or termination of this Lease, or summary proceedings,
abandonment or vacancy, shall relieve the Tenant of any of its liabilities and
obligations under this Lease (whether or not any or all of the Premises are
relet); accordingly, in any such event the Tenant shall pay to the Landlord the
Rent and all other charges required to be paid by Tenant up to the time of such
event, and thereafter

(a) at any time after the expiration or termination of this Lease pursuant to
this Section 16, in lieu of collecting any further monthly installments, as
aforesaid, the Landlord shall be entitled to recover from the Tenant, and the
Tenant shall pay to the Landlord, on demand, damages computed in the manner
set forth in clause (i) of subparagraph 16.3.2(b), minus the amount of any such
monthly installments previously recovered from the Tenant; and

(b) in the case of any Event of Default under the provisions of paragraphs
16.1.2 or 16.1.3, the Landlord shall immediately and automatically, without the
necessity of notice or other action by the Landlord, become entitled to recover
from the Tenant as damages for such breach, in addition to any damages or
other payments becoming due from the Tenant under any other provision of this
Lease, an amount equaling the difference between the Base Rent and the
Additional Rent reserved in this Lease from the date of such breach to the
date of the expiration of the Term and the then-fair and reasonable rental value
of the Premises for the same period. Such damages shall become due and payable
to the Landlord immediately upon the occurrence of such Event of Default and
without regard to whether or, if so, how this Lease is terminated.

16.3.3. Each party hereto hereby waives any right which it may otherwise have at
law or in equity to a trial by jury in connection with any suit or proceeding at
law or in equity brought by the other against the waiving party or which
otherwise relates to this Lease, as a result of an Event of Default or
otherwise.

16.4. Default by Landlord. If the Landlord violates any of its obligations under
the provisions of this Lease, the Tenant may (subject to the operation and
effect of the provisions of paragraph 4.2.3, requiring the Tenant to pay all
Rent when due, without deduction or set-off whatsoever) exercise any right or
remedy which it holds on account thereof hereunder, at law or in equity;
provided, that if any or all of the Premises is then subject to any first
Mortgage, the Tenant shall not exercise any of its rights or remedies on account
thereof unless and until it has given written notice of its intention to do so,
by certified or registered mail, return receipt requested, to the Mortgagee
under such first Mortgage, specifying therein the nature of such default in
reasonable detail, and unless such Mortgagee has not cured such default on the
Landlord's behalf within thirty (30) days after such notice is given.

Landlord or such other addressee; and

17.2. acknowledging and agreeing that any statement contained in such
certificate may be relied upon by the Landlord and any such other addressee.
