proceeding or proceedings, nor the entering of judgment therein shall bar

on the part of Landlord in the institution of any suit or entry of judgment for
any part of the rent herein reserved to Landlord, including, but not limited to,
the unliquidated percentage rent then due, shall in no way serve as a defense
against nor prejudice a subsequent action for such rent. Tenant hereby expressly
waives Tenant's right to claim a merger of such subsequent action in any
previous suit or in the judgment entered therein. Furthermore, it is expressly
agreed that claims for liquidated or minimum annual rent may be regarded by
Landlord, if it so elects, as separate claims capable of being assigned.

proceeding provided for by law (notwithstanding the fact that such is not
otherwise provided for herein) against Tenant from time to time to recover any
of the aforesaid sums which, at the commencement of any such action, writ or
proceeding shall then or theretofore have become due and payable to the Landlord
under any provisions hereof, without waiting until the end of the original term
of this Lease, and neither the institution of such action, suit or proceeding
nor the settlement thereof of entering of judgment there in shall terminate this
Lease, nor shall it bar Landlord from bringing subsequent actions, suits or
proceedings from time to time for any sum or sums of any kind which shall
thereafter become due and owing from Tenant to Landlord under any of the terms
hereof or otherwise. Tenant hereby expressly waives any right or defense which
it may have to claim a merger of such subsequent actions, suits or proceedings
in any previous action, suit or proceeding or in the settlement thereof or
judgment entered therein.

deemed and declared to be "Additional Rent" under the terms of this Lease and

Tenant agrees to execute such instruments of assignment as may be required by
Landlord, to join with Landlord in any petition for the recovery of damages, if
requested by Landlord, and to turn over to Landlord any such damages that may be
recovered in any such proceeding. If Tenant shall fail to execute such
instruments as may be required by Landlord or to undertake such other steps as
may be requested as herein stated, then and in any such event Landlord shall be
deemed the duly authorized irrevocable agent and attorney-in-fact of Tenant to
execute such instruments and undertake such steps as herein stated in and on
behalf of Tenant. It is agreed and understood, however, that Landlord does not
reserve to itself, and Tenant does not assign to Landlord, any damages payable
for trade fixtures installed by Tenant at its own cost and expense which are not
part of the realty or Tenant's damage for interference or deprivation of use.

ARTICLE THIRTY-FOUR - PAYMENT OF MORTGAGE, TAXES, ETC.

hereunder shall be first applied and paid over to make and satisfy all payments
required under the existing mort-gage(s) on the Demised Premises and all real
estate taxes and any other charge or assessment which if remaining unpaid would
constitute a lien upon the Demised Premises, as the same become due. In the

provisions of this Article, then Tenant shall have the right (but not the
obligation) to make such payment(s) directly to the mortgagee, taxing authority
or other levying agency and to deduct such payment(s) from the next ensuing rent
payment(s) hereunder.

of rental payments required under the Lease and Tenant shall not be in default
under the lease by virtue of its payment of such funds to Broker on behalf of
Landlord.

     7:26B-10.1. Tenant shall store and handle such substances in accordance

          (3) If Tenant shall seek to acquire ISRA Approval by obtaining a
     non-applicability determination based upon operations of Tenant in the
     Demised Premises falling within a standard industrial classification number
     ("SIC Number"), which is outside the scope of ISRA, Tenant shall submit to
     Landlord not earlier than thirty (30) days prior to Termination, and not

     any duty or obligation provided by this Lease.

          (5) Landlord shall receive for its review and comment a copy of any

     other regulatory agency concerning matters rising out or relating to ISRA.

     Lease.

          (7) Landlord shall have the opportunity to participate with Tenant in
     negotiations with the NJDEP leading to the obtaining by Tenant of a
     certification from NJDEP that Tenant has complied with all of its

     or ISRA, may be relied upon by Landlord and shall be considered a
     representation made directly to the Landlord which shall survive
     Termination, and inure to the benefit of Landlord.

          (9) Tenant shall timely inform Landlord of any proposed sampling of
     soil sediment, air, groundwater, surface water or other samples in or near

                                      -38-
<PAGE>

     NJDEP, as well as any other reports obtained by Tenant relating in any way
     to the environmental condition of the Building or property nearby.

     C. Cleanup Plan. (1) Should NJDEP require that a cleanup plan be prepared
and that cleanup be undertaken (the "Cleanup Plan") , because of any spills or
discharges of hazardous substances or wastes in, upon, or about the Building, or
the threat thereof , by reason of the conduct of Tenant, its agents employees,
contractors or invitees, then Tenant shall prepare and submit the required plan
and financial assurances required by ISRA and, subject to the provisions of
subparagraph (4) below, comply with and perform the work required by the Cleanup
Plan.

          (2) Tenant shall, upon request of Landlord, deposit with Landlord

     as reasonably estimated by Landlord. Portions of the amount deposited with

     the costs of performance of the Cleanup Plan, provided that at least
     twenty-five percent (25%) of the estimated cost of the balance of the costs
     of compliance with the Cleanup Plan (as reasonably estimated by Landlord)
     remain in the fund held by Landlord until issuance of a Certification by
     NJDEP of compliance with and completion of the Cleanup Plan.

          (3) Tenant shall utilize its own identification number or code as
     provided or to be provided by the United States Environmental Protection

<PAGE>

          (4) Tenant shall be responsible for the cost of repair or replacement

          (5) Tenant shall implement and institute any reasonable safety
     measures in connection with any work in, about or near the Building by
     reason of its obligations under this Article Forty-Five, as Landlord may
     reasonably request, and, in addition thereto, Tenant shall perform such
     work at such hours as shall be designated by Landlord in order to avoid
     interference with the operations of the Building and the conduct of
     business therein by the tenants.

          (6) Landlord may, in its reasonable discretion, determine that the
     execution of the Cleanup Plan and the work required thereunder affect
     portions of the Building or property other than the Demised Premises, the
     operation hereof or other tenants therein, and in such instance, Landlord
     may, complete or cause the work required to be completed pursuant to the
     Cleanup Plan at Tenant's cost, and any funds deposited by Tenant with
     Landlord may be applied to the cost of such work by Landlord.

     D. Failure to Obtain ISRA Approval Prior to Termination. Tenant
acknowledges that the failure by Tenant to receive ISRA Approval may adversely
affect Landlord's ability to operate the Building, lease space therein, or
otherwise mortgage, finance or sell the Building and that the damages which may
be sustained by Landlord as a result thereof may be substantial and are not
easily susceptible to definitive computation. Accordingly, Tenant shall be
responsible for and pay to Landlord an amount equal to one three hundred
sixty-fifth (1/365th) of the aggregate of the highest amount of Minimum Rental
and Additonal Rent payable by Tenant in any Lease


                                      -40-
<PAGE>

year during the five (5) year period immediately preceding the expiration or
termination multiplied by two (2) for each day after termination that Tenant has
failed to obtain ISRA approval, diminished by any rental or other revenues
received by Landlord by reason of the occupancy of the Demised Premises during

was caused by the State and not of its own doing; this penalty shall not be
applied.
