                                     LEASE

            THIS AGREEMENT OF LEASE (together with all Exhibits and Schedules
attached or to be attached hereto, this "Lease") is dated as of June 28, 2000,
between THE CONNELL COMPANY, a New Jersey corporation, whose address is 45
Cardinal Drive, Westfield, New Jersey 07090 (subject to Section 10.04 hereof,
"Landlord") and GENTA INCORPORATED, a Delaware corporation whose address is 99
Hayden Avenue, Suite 200, Lexington, Massachusetts 02421("Tenant").

            Landlord hereby leases to Tenant and Tenant hereby rents from
Landlord the Demised Premises (hereinafter defined) for the Term (hereinafter
defined) at the rent and subject to all of the terms and conditions set forth
herein. Intending to be legally bound hereunder and in consideration of $1.00
and other good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, Landlord and Tenant hereby agree with each other as
follows:

                       ARTICLE I. BASIC LEASE INFORMATION

            Section 1.01. Building and Land; Real Estate:

            The "Building" is Connell Corporate Center II, Two Oak Way, Berkeley
Heights, New Jersey 07922. The Land shall mean all that real property which is
more particularly described in Exhibit A attached hereto and made a part hereof.
The Building and the Land are sometimes referred to collectively herein as the
"Real Estate."

            Section 1.02. Demised Premises:

            The Demised Premises is the portion of the Building leased to
Tenant, including terrace, if any, consisting of 10,455 usable square feet of
floor area converted to 12,807 rentable square feet of floor area by multiplying
the usable square feet by 122.5%, and located on the second floor and designated
as "Demised Premises" on the "Rental Plan" (which is attached hereto as Exhibit
B). The Demised Premises includes any alterations, additions, improvements or
repairs of any nature made thereto. This computation of rentable square footage
shall be binding and conclusive on the parties and their successors and assigns.

            Section 1.03. Base Rent:

            "Base Rent" shall be an amount equal to $25.00 per rentable square
foot, or $320,175.00 in the aggregate per annum ($26,681.25 per month); and
shall be payable per Section 5.01 hereof (it being understood that payment for
electricity per Section 8.02 hereof (which, as of the date hereof, is $1,440.79
per month) is an amount in addition to Base Rent); provided, however, that
during any Renewal Term, Base Rent shall be an amount determined pursuant to
Section 4.01 (b) hereof.
<PAGE>
            Section 1.04. Letter of Credit:

            (a) Tenant shall cause an irrevocable, transferable letter of
credit, substantially in the form of Exhibit F attached hereto (the "Letter of
Credit"), to be issued and outstanding in favor of Landlord, at all times from
the date hereof until sixty (60) days after the expiration or earlier
termination of this Lease. Each Letter of Credit shall (i) be issued by a
domestic United States financial institution with a credit rating of at least A1
by Moody's Investors Service, Inc. (or upon modification or replacement of such
financial rating system, its then equivalent rating) (the "Required Credit
Rating") and otherwise acceptable to Landlord (the "Letter of Credit Provider"),
(ii) have an expiration date of not earlier than one calendar year following the
date of issue, (iii) at all times be in an available amount (the "Required
Letter of Credit Amount") of not less than nine (9) months of Base Rent, which
as of the date hereof is $240,131.25, and (iv) provide that during the Term it
shall be automatically extended for an additional period of one year from the
scheduled expiration date unless at least thirty (30) days prior to such date
Landlord receives from the Letter of Credit Provider thereof notice in writing
that such Letter of Credit Provider elects not to renew such Letter of Credit
for such additional period. If the Letter of Credit Provider elects not to renew
such Letter of Credit for such additional period, then Tenant shall cause a new
Letter of Credit to be issued in replacement thereof from a Letter of Credit
Provider at least fifteen (15) days prior to the expiration date of the existing
Letter of Credit; provided, however, that Tenant shall not permit an existing
Letter of Credit to expire until such new Letter of Credit has been issued.

            (b) If, while a Letter of Credit is required to be outstanding
hereunder, the financial rating of the Letter of Credit Provider providing the
Letter of Credit is less than the Required Credit Rating, then Landlord may
require Tenant to provide, and Tenant shall provide, a replacement Letter of
Credit issued by a Letter of Credit Provider with a credit rating that meets the
Required Credit Rating within thirty (30) days of demand therefor by Landlord,
which replacement Letter of Credit shall comply with the terms of Section
1.04(a) hereof, provided that nothing in this Section 1.04(b) shall affect the
obligations of Tenant under Section 1.04(a) hereof. Promptly following receipt
of such replacement Letter of Credit, Landlord shall surrender the Letter of
Credit being replaced to the Letter of Credit Provider thereof.

            (c) Notwithstanding the foregoing, on the one year anniversary of
the Commencement Date and each anniversary thereafter, Landlord may (by
providing written notice thereof to Tenant) reduce the Required Letter of Credit
Amount by an amount equal to two (2) months of Base Rent if (i) Tenant shall
have provided Landlord with Tenant's audited financial statements for the prior
year (and any other financial statements required under Section 20.18 hereof),
(ii) Landlord decides, in its sole discretion, that the financial condition of
Tenant merits that the Required Letter of Credit Amount be so reduced and (iii)
no Event of Default shall have occurred at any time during the Term; provided,
however, that in no event shall the Required Letter of Credit Amount be less
than an amount equal to three (3) months of Base Rent.

            Section 1.05. Term:

            The "Term" of this Lease shall commence on the Commencement Date and
shall continue for five (5) years thereafter (provided that if the Commencement
Date is not the first day of a month, then in addition to such five (5) year
period, the Term shall include an additional number of days equal to the number
of days in the period from and including the Commencement Date to and including
the last day of the month (of the same year) on which the Commencement Date
occurred), unless sooner terminated or renewed in accordance with the provisions
of this Lease. If Tenant exercises the Renewal Option pursuant to Section
4.01(a) hereof, the "Term" shall include the renewal period.

            Section 1.06. Tenant's Pro Rata Share:

            For purposes of this Lease, Tenant's Pro Rata Share shall be the
ratio of the total rentable square footage of the Demised Premises to the total
rentable square footage of the Building. Landlord and Tenant have determined
that Tenant's Pro Rata Share is 4.103%, calculated as follows: Demised Premises
of 12,807 rentable sq. ft. divided by the rental Area of Building of 312,143 sq.
ft. = 0.04103 x 100 = 4.103%. This determination of Tenant's Pro Rata Share
shall be binding and conclusive on the parties, and their successors and
assigns.

            Section 1.07. Relocation:

            At any time and from time to time during the Term, on at least
thirty (30) days prior notice to Tenant, Landlord shall have the right to move
Tenant out of the Demised Premises and relocate Tenant to other space within
Connell Corporate Center for the balance of the Term. In the event Landlord
exercises this right of relocation, Landlord shall, at its sole cost and
expense, decorate the new premises substantially similarly to the Demised
Premises and shall remove, relocate and reinstall Tenant's furniture, trade
fixtures, furnishings and equipment. Upon completion of all work in the
substitute premises, Tenant shall surrender the Demised Premises. Following the
relocation, this Lease shall continue in full force and effect; provided,
however, that (a) the description of the Demised Premises, the Building and the
Real Estate, shall be deemed to be amended to describe the new premises; and (b)
the Rent shall be appropriately modified if the square footage of the new
premises is not the same as that of the original Demised Premises.

                            ARTICLE II. DEFINITIONS.

            Section 2.01. As used herein, the terms below shall have the
following meanings:

            (a) "Appraisal Procedure" shall mean the following: within ten (10)
days after the expiration of the thirty (30) day period specified in Section
4.01(b) hereof, each party shall appoint a disinterested, independent appraiser
who is a member of the American Institute of Real Estate Appraisers (or a
successor organization or, if none exists, the closest similar organization) and
has at least five years experience appraising rental properties in the Berkeley
Heights area (which shall include the Route 78 corridor from and including Exit
43 to and including Exit 33) (an "Appraiser"). Within twenty (20) days after
their appointment, the two Appraisers so appointed shall appoint a third
Appraiser. If no such third Appraiser is appointed within thirty (30) days after
the appointment of the two Appraisers, then either party may apply to the
American Arbitration Association ("AAA") to make such appointment, and both
parties shall be bound by such appointment. Each Appraiser appointed pursuant to
the foregoing procedure shall be instructed to determine the amount of Market
Rent within twenty (20) days after his or her appointment. Each of the three
Appraisers shall determine the value of Market Rent applying the parameters set
forth in Section 4.01(b). The values of the Market Rent determined by each of
the three Appraisers shall then be averaged, the determination which differs
most from such average shall be excluded, the remaining two values shall then be
averaged, and such average shall be the Market Rent, which shall be final and
binding on the parties. The expenses and fees of all such Appraisers shall be
shared equally between Landlord and Tenant.


                                       3
<PAGE>
            (b) "Assessed Valuation" shall mean the assessed valuation of the
Real Estate, including any added and/or omitted assessments, as determined by
the real estate tax records of the Township of Berkeley Heights.

            (c) "Base Rent" shall have the meaning set forth in Section 1.03 of
this Lease.

            (d) "Base Tax Rate" shall mean the real estate tax rate in effect
for the calendar year 2001.

            (e) "Building" shall have the meaning set forth in Section 1.01 of
this Lease.

            (f) "Building Operating Costs" shall have the meaning set forth in
Section 5.03(c),(d) and (e) of this Lease.

            (g) "Business Hours" shall mean, at a minimum, the Business Hours
specified in Paragraph 5 of Exhibit D to this Lease, plus any additional hours
or days hereafter designated by Landlord as Business Hours; it being understood
that Landlord reserves the right to change the days designated as "Holidays" on
such Exhibit D as provided in this Lease.

            (h) The "Commencement Date" of this Lease shall be the earliest of
(i) the day on which Tenant, having completed the Tenant Work, obtains a
Certificate of Occupancy for the Demised Premises; or (ii) the day on which
Tenant commences to do business in the Demised Premises; or (iii) November 1,
2000; provided, however, in the event (I) the Tenant Work shall not be completed
by November 1, 2000 as a direct result of the failure of the Landlord to respond
to plan approval requests made by Tenant with respect to the Tenant Work within
fifteen (15) business days following Landlord's receipt of such a request or
(II) the Tenant Work shall not be completed, and a Certificate of Occupancy
shall not have been obtained, by November 1, 2000 as a direct result of the
existence, prior to the commencement of the Tenant Work, of a material latent
defect in the base Building (provided, however, that this clause (II) shall only
be applicable if Tenant shall have notified Landlord, in writing, of the
existence of such latent defect at the time of such discovery, and the parties
reasonably agree that the existence of such material latent defect is material
to the completion of the Tenant Work), then the Commencement Date shall be
extended by the number of days late (i.e., beyond the 15 business day period)
Landlord's response was to such plan approval request (or, as applicable, the
number of days which the existence of the latent defect directly contributed to
such delay), but in any such case the Commencement Date shall not be extended to
a date beyond the earlier to occur of (x) the completion of the Tenant Work (and
the date a Certificate of Occupancy for the Demised Premises is obtained) or (y)
the date on which Tenant commences to do business in the Demised Premises.
Within 30 days after the Commencement Date the parties shall execute a
Commencement Date Addendum in the form attached as Exhibit G to this Lease;
provided, however, that the failure by either party to execute such Commencement
Date Addendum (i) shall not in any way affect the date of the Commencement Date
or any of the terms of this Lease and (ii) shall not constitute a breach of this
Lease.

            (i) The "Common Area" shall mean, collectively, without limitation,
the hallways, entryways, stairs, cafeteria, elevators, driveway, sidewalks,
parking areas, loading areas, trash facilities, and all other areas and
facilities of the Building and the Land provided from time to time by Landlord
for the general use and convenience of Tenant with other tenants and their
respective employees, servants, invitees, licensees or other visitors.

            (j) "Demised Premises" shall have the meaning set forth in Section
1.02 of this Lease.

            (k) "Expiration Date" shall be the last day of the Term. If this
Lease shall have been renewed, the Expiration Date shall be the last day of the
Term as so renewed. Notwithstanding anything otherwise to the contrary herein,
if this Lease is cancelled or terminated prior to the Expiration Date by

design, demolition and construction, in accordance with this Article III and
Exhibits C-1 and C-2.

shall be annexed hereto and, as of the date of such annexation, made a part of
this Lease as Exhibit [C-1] and shall be referred to as the "Plans and
Specifications." The Tenant Workletter, annexed hereto as Exhibit C-2, sets

                  (i). Landlord has furnished Tenant with a written list of
                  contractors which Landlord has pre-approved to perform work in
                  the Building (the "Pre-Approved Contractors"). Prior to

                  written list of contractors who are proposed to perform such
                  work, if any, who are not Pre-Approved Contractors. All
                  contractors (whether or not such contractors are Pre-Approved
                  Contractors) shall be first-class union contractors and shall
                  maintain current licenses with applicable governmental and/or
                  other enforcement authorities. Tenant shall furnish to
                  Landlord copies of such contractors' insurance policies

                  Contractors), including workers compensation, public liability
                  and property damage, all in amounts and with companies

                  reject any such proposed contractors who are not Pre-Approved
                  Contractors by written notice to Tenant within ten days of
                  Landlord's receipt of the above information.

                  permits legally required in connection with the performance of
                  Tenant Work. If necessary, Landlord shall join in the
                  execution of the applications, and at Tenant's request, shall
                  cooperate with the prosecution of the application. Tenant
                  shall bear all fees, costs and expenses in connection with the
                  applications including any legal or other expenses incurred by
                  Landlord. Tenant shall prosecute the applications diligently
                  and use reasonable efforts to seek the approvals and permits
                  applied for and shall provide Landlord with copies of all
                  permits and approvals upon receipt thereof. Tenant shall
                  advise Landlord of its progress from time to time and upon
                  request by Landlord.

                  (iii). Promptly after all requisite approvals and permits have
                  been granted, Tenant shall commence the performance of Tenant
                  Work and shall diligently prosecute Tenant Work to completion.

                  (iv). Tenant shall perform or cause to be performed all of
                  Tenant Work in accordance with the Plans and Specifications,
                  all requirements of regulations of any applicable public
                  authority, and the terms and conditions of all insurance
                  policies and shall do so in a good and workmanlike manner.
                  Notwithstanding any failure by Landlord to object to any such
                  Tenant Work Landlord shall have no responsibility therefor.

                  (v). Tenant's contractors shall have access to the Demised
                  Premises during Business Hours and Landlord shall provide
                  water, heating or cooling to the extent such services are
                  being provided to the Demised Premises pursuant to the terms
                  of this Lease. Tenant's contractors may have access to the
                  Demised Premises beyond Business Hours, and water, heating or
                  cooling at Tenant's request, if Tenant agrees to pay utility
                  overtime charges on an hourly basis as set forth in the Rules
                  and Regulations (defined herein).

                  (vi). Tenant shall provide Landlord with "as built drawings"
                  upon completion of Tenant Work.

                  (vii). If any governmental authority requires that a
                  certificate of occupancy be issued with respect to the Demised
                  Premises as a result of Tenant Work, Tenant shall apply for,
                  obtain such certificate of occupancy and provide a copy
                  thereof to Landlord.

            Section 3.02. Tenant's Early Access:

            (a) Landlord shall permit Tenant to enter the Demised Premises
before Tenant Work is undertaken during normal Business Hours for the purposes
of inspection only.

            (b) Once Landlord shall have approved the Plans and Specifications,
Tenant shall be permitted to install furniture, computers and similar items in
the Demised Premises prior to the Commencement Date. If Tenant is permitted any
access to the Demised Premises prior to the Commencement Date (including without
limitation pursuant to the preceding sentence), it shall be at Tenant's sole
risk (except to the extent caused by the gross negligence or willful misconduct
of Landlord). If Tenant's workmen begin to perform Tenant Work, the foregoing
license is conditioned upon Tenant's Agents not interfering with Landlord's
employees, agents, servants, representatives or licensees, or the workmen of any
other tenant. Landlord shall not be liable in any way for any injury, loss or
damage of any nature whatsoever occurring as a result of early access to the
Demised Premises by Tenant or any employee, agent, servant, contractor or
representative thereof, except to the extent caused by the gross negligence or
willful misconduct of Landlord. Landlord shall have the right to impose such
additional conditions on tenant's early entry as Landlord, in its reasonable
discretion, deems appropriate.

            Section 3.03. Insurance Covering Tenant Work:

            Tenant shall not make or cause to be made any alterations, repairs
or installations, or perform Tenant Work or any other work to or on the Demised
Premises unless Tenant shall obtain, or shall require all its contractors to
obtain, and have in force during the performance of such work, public liability
and worker's compensation insurance to cover every contractor to be employed as
set forth in Section 3.01(b)(i) hereof. Such policies shall be in such amounts
and on such terms as Landlord deems appropriate; they shall be non-cancellable
without thirty (30) days' prior notice to Landlord by the insurance company. In
accordance with Section 3.01(b)(i) hereof, Tenant shall supply Landlord with
copies of the insurance policies prior to commencing any Tenant Work.

            Section 3.04. Certain Landlord Representations; No other
Representation:

            (a) Landlord represents and warrants to Tenant that, to the best of
Landlord's knowledge, (i) the base Building and the Common Areas are in
compliance with all applicable laws and regulations, including without
limitation building codes, environmental laws and the Americans with
Disabilities Act; (ii) all applicable certificates of occupancy and other
required permits with respect to the base Building and Common Areas have been
obtained and are in full force and effect; and (iii) there are no outstanding
violation notices with respect to any portion of the Building which if not
corrected would delay or prevent the issuance to Tenant of any required building
permits or certificates of occupancy or similar permits and approvals for the
Tenant Work and/or for Tenant's occupancy of the Demised Premises.

            (b) Landlord has made and makes no representations, covenants or
warranties with respect to the Demised Premises, the Building or the Land,
except as expressly set forth in this Lease.

                          ARTICLE IV. OPTION TO RENEW.

            Section 4.01. Option to Renew.

            (a) Tenant shall have one option to renew this Lease (a "Renewal
Option") on the same terms and conditions and in the manner set forth below, for
a term of five (5) years, provided that there has been no Event of Default (or
event or condition which, with the passage of time or giving of notice, or both,
would constitute an Event of Default) that has occurred and is continuing at the
time of exercise of the option and that there have not been repeated recurring
Events of Default (whether or not previously cured) during the Term. In the
event Tenant desires to elect the Renewal Option, Tenant shall give Landlord
written notice of its exercise of the Renewal Option nine (9) months prior to
the Expiration Date of the Term. If Tenant fails to timely notify Landlord of
its exercise of the Renewal Option, then the Renewal Option shall expire.

            (b) Base Rent during the renewal term shall equal the prevailing
market rental rate for office space of comparable quality, design and location
in the Berkeley Heights area (which shall include the Route 78 corridor from and
including Exit 43 to and including Exit 33) for tenants occupying an amount of
space comparable to the amount then leased by Tenant, taking into consideration
any concessions (e.g., rent abatement, tenant improvement and other allowances;
it being understood for purposes of clarification that Landlord shall have no
obligation to provide Tenant with any tenant improvement allowance) then being
offered by landlords to prospective tenants for comparable space ("Market
Rent"), but in no case less than the then existing Base Rent. The parties shall
negotiate in good faith to establish the Market Rent. If the parties are unable
to agree on Market Rent within thirty (30) days after Tenant gives Landlord its
notice exercising the Renewal Option (the "Notice Date"), then the Appraisal
Procedure (as defined in Section 2.01) shall be utilized.

                                ARTICLE V. RENT.


                                       8
<PAGE>
            Section 5.01. Base Rent:

            Tenant shall pay Base Rent to Landlord, in the amount set forth in
Section 1.03, without notice or demand, in equal monthly installments in advance
beginning on the Commencement Date. Each subsequent installment shall be due to
and received by the Landlord on or before the first day of each month during the
Term. Notwithstanding the foregoing, in the event the Commencement Date is not
the first day of the month, on the Commencement Date Tenant shall pay Landlord
an amount equal to $924.56 (consisting of $877.19 for Base Rent and $47.37 for
electric) for each day of such first "partial" month of the Term.

            Section 5.02. Tax Increase Amount:

            (a) In addition to Base Rent and all other charges Tenant is
required to pay hereunder, Tenant shall pay the Tax Increase Amount (as
hereinafter defined) to Landlord as follows:

                  (i) If the Taxes for any Tax Year during the Term of this
            Lease shall be greater than the Real Estate Tax Base, then Tenant
            shall pay to Landlord, as a component of Rent and as provided in
            Section 5.02(a)(ii) below, the amount (the "Tax Increase Amount")
            determined by multiplying the difference between the Taxes for the
            applicable Tax Year and the Real Estate Tax Base by Tenant's Pro
            Rata Share. If the Taxes for any Tax Year during the Term of this
            Lease shall be less than the Real Estate Tax Base, then Landlord
            shall refund to Tenant as provided in Section 5.02(a)(ii) below, the
            amount (the "Tax Decrease Amount") determined by multiplying the
            difference between the Real Estate Tax Base and the Taxes for the
            applicable Tax Year by Tenant's Pro Rata Share.

                  (ii) Within one hundred and eighty (180) days after the
            commencement of each Tax Year after and including the year in which
            the Assessed Valuation has been established, or as soon as
            practicable thereafter, Landlord shall submit to Tenant a copy of
            the bill(s) for the Taxes for such Tax Year and a statement (the
            "Tax Statement"), which shall indicate: (i) any annual increase (or
            decrease) in the Taxes, (ii) the effective date of such increase (or
            decrease), (iii) the Tax Increase Amount due, if any, (iv) the Tax
            Decrease Amount, if any, to be refunded and (v) any Extra Taxes due
            as set forth below. Tenant shall pay the Tax Increase Amount to
            Landlord within thirty (30) days after the issuance of the Tax
            Statement. Landlord shall pay the Tax Decrease Amount to Tenant
            within thirty (30) days after the issuance of the Tax Statement. Any
            Tax Increase Amount or Tax Decrease Amount for a period of less than
            a full Tax Year shall be ratably apportioned.

            (b) Tenant shall be liable for any portion of the Taxes, charges and
assessments imposed upon the Real Estate during the Term of this Lease which are
attributable to extraordinary improvements in the Demised Premises or the
Building constructed at Tenant's expense or for Tenant's specific benefit and
for which the taxing authority has assigned a distinguishable increase in
valuation in computing the Assessed Valuation ("Extra Taxes"). Tenant shall pay
to Landlord such Extra Taxes within thirty (30) days after issuance of the Tax
Statement as set forth above. Any Extra Taxes due for a period of less than a
full year shall be ratably apportioned. Tenant shall not be liable for any Extra
Taxes attributable to the improvements of any other Tenant.

            (c) Tenant's obligations for payment of Tax Increase Amount or Extra
Taxes during the Term shall survive the expiration or early termination of this
Lease.

            Section 5.03. Building Operating Costs, Adjustments:

            (a) Tenant hereby agrees that for each Operating Year during the
Term of this Lease for which the Building Operating Costs (as hereinafter
defined) budgeted for such Operating Year exceeds the Building Operating Costs
for the First Operating Year, Tenant shall pay to Landlord as a


                                       9
<PAGE>
component of Rent and in the manner further provided in this Section 5.03, an
amount (the "Operating Increase Amount") determined by multiplying the
difference between the budgeted Building Operating Costs for the applicable
Operating Year and the Building Operating Costs in the First Operating Year by
Tenant's Pro Rata Share. Within one hundred and eighty (180) days after the
commencement of each Operating Year, or as soon as practicable thereafter,
except for the First Operating Year, Landlord shall present to Tenant a
statement (the "Operating Statement") showing, inter alia, the Operating
Increase Amount, if any, due hereunder (the date upon which the Operating
Statement is presented to Tenant being hereinafter referred to as the "Billing
Date"). Tenant shall pay the Operating Increase Amount no less frequently than
monthly in advance in an amount determined by multiplying the Operating Increase
Amount for the applicable Operating Year by one-twelfth (1/12). These monthly
payments of the Operating Increase Amount shall be added to and paid
simultaneously with the Base Rent. If the total of such monthly payments made by
Tenant during any Operating Year is less than the Operating Increase Amount, as
shown on the next Operating Statement presented to Tenant, Tenant shall pay the
difference to Landlord within thirty (30) days after the Billing Date. If the
total of such monthly payments made by Tenant during any year is greater than
the Operating Increase Amount, as shown on the next Operating Statement
presented to Tenant, Landlord shall refund the excess amount to Tenant within
thirty (30) days after the Billing Date. Each Operating Statement shall indicate
(i) the Operating Increase Amount for the current year; (ii) the difference
between the actual dollar amount of Building Operating Costs and the budgeted
Building Operating Costs for the preceding Operating Year; (iii) the total of
the monthly payments made by Tenant hereunder for the account of the preceding
Operating Year, if applicable; and (iv) the amount of any overpayment or
underpayment by Tenant on account of the Operating Increase Amount for the
preceding year.

            (b) If Tenant disputes the amount or characterization of any item
contained in the Operating Statement by giving written notice thereof to
Landlord within sixty (60) days of the Billing Date, Tenant shall have the right
to designate a firm of independent certified public accountants to audit
Landlord's records upon which the Operating Statement is based, provided Tenant
first pays all sums due as shown on the Operating Statement first. Such audit
shall be conducted promptly after Tenant's notice of dispute is given to
Landlord. The fee for any audit conducted on Tenant's behalf shall be borne
solely by Tenant (subject to the penultimate sentence of this Section 5.03(b)).
Landlord shall have the right, at its sole expense (subject to the last sentence
of this Section 5.03(b)), to have Tenant's audit reviewed by a mutually agreed
upon third party nationally recognized certified public accountant, whose
determination shall be conclusive and binding on both Landlord and Tenant. If,
as a result of Tenant's inspection of Landlord's books or the audit of
Landlord's records and review by independent certified public accountants, an
error is discovered in the Operating Statement, Landlord shall revise the
Operating Statement accordingly and any overpayment by Tenant shall be refunded
by Landlord to Tenant forthwith and any underpayment shall be paid by Tenant on
demand. Any audit and subsequent adjustment in payment shall be deemed to be
conclusive of settlement of the dispute. If Tenant does not notify Landlord of a
dispute within sixty (60) days of receipt of any Operating Statement, Tenant
shall be deemed to have accepted such Operating Statement. Landlord's records
and any information provided by Landlord to auditors pursuant to this Section
5.03(b) shall be and remain confidential and shall not be made available by the
auditors or Tenant to any other person or entity, except to persons or entities
named in subpoena or other legal process, but only such portion of such
information that, in the reasonable opinion of Tenant's counsel, is required to
be disclosed in response to such process; provided, however, that Tenant shall,
before making the disclosure, promptly inform Landlord of Tenant's receipt of
any such subpoena or other process so as to afford Landlord the opportunity to
seek a protective order if it so desires. If the final audit discloses an error
in Landlord's determination of the Building Operating Costs in excess of five
percent (5%) in Landlord's favor, then all costs of the audits shall be borne by
Landlord. If the final audit discloses that Landlord's determination of the
Building Operating Costs was not in error in excess of two percent (2%) in
Landlord's favor, then all costs of the audits shall be borne by Tenant.

            (c) The "Building Operating Costs" shall include each and every
expense incurred in connection with the ownership, administration, management,
operation, insurance, maintenance and repair of the Real Estate, or reasonably
charged by Landlord if Landlord performs management services in connection with
the Real Estate, including management, consulting, reasonable legal and
accounting


                                       10
<PAGE>
fees, and, further, including but not limited to, wages, salaries and fees paid
to persons either employed by Landlord or engaged as independent contractors in
performing or managing the services related to the Real Estate, and such other
typical items of expense as indicated in Subsection (d) below. If any person or
independent contractor is employed with respect to more properties than the Real
Estate, the wages, salaries or fees paid therefor shall be allocated based on
time spent by such person or Contractor on matters relating to the Real Estate
(excluding time spent on items which are not Building Operating Costs) or the
degree of responsibility for the Real Estate compared to the other properties
involved.

            (d) Some of the typical items of expense which comprise or may
comprise the Building Operating Costs are or may be the following, but only to
the extent that they relate solely or are properly allocated to the Real Estate:

                  (i) Repairs and maintenance;

                  (ii) Utility costs, including but not limited to the cost of
            electricity to power HVAC units and to heat and light the Common
            Area;

                  (iii) Cleaning costs, including but not limited to windows,
            tenant premises and Common Areas;

                  (iv) Service contracts including but not limited to elevator,
            HVAC, janitorial and window cleaning, rubbish removal, exterminating
            and towel service;

                  (v) Costs of landscaping and snow removal;

                  (vi) Cost of redecorating Common Area;

                  (vii) Wages, salaries and other compensation, including taxes,
            insurance, retirement, fringe benefits, uniforms payable to
            employees performing services related to the Real Estate;

                  (viii) Reasonable fees and other compensation payable to
            independent contractors or other agents of Landlord performing
            services related to the Real Estate;

            to, fire and extended coverage, public liability and property,

            Amount and estimated Operating Increase Amount), elevator, worker's
            compensation, boiler and machinery insurance;

within the Demised Premises, ordinary wear and tear excepted. Notwithstanding
the foregoing, Landlord shall make all repairs required by the occurrence of
fire and other casualty as more particularly set forth in Section 12.03 hereof;

of the Demised Premises; it being understood that the provisions of Article III
hereof shall govern the Tenant Work. Any permitted alterations shall be
performed in a good and workmanlike manner in accordance with all requirements
of any applicable governmental authority, the terms and conditions of all

or replacements otherwise required to be made by Tenant, Landlord may enter the
Demised Premises, and proceed to make or cause such repairs or replacements to
be made at Tenant's expense. Landlord shall give Tenant telephone notice of such
emergency. Within thirty (30) days after Landlord renders a bill for such
repairs or replacements, Tenant shall reimburse Landlord for the cost of making
such repairs. Landlord's access and entry into the Demised Premises shall, to
the extent practicable under the circumstances, be conducted in a manner which
shall not unreasonably disrupt or unreasonably interfere with Tenant's use and
conduct of business within the Demised Premises.

            Section 7.05. Electrical Lines

            (a) Tenant may not install any electrical equipment that overloads
the lines in the Demised Premises, the Building or the Real Estate or which will

above. If Tenant makes such installation, Landlord may require Tenant, at
Tenant's sole cost and expense, to make whatever alterations and/or repairs are
necessary and which are in compliance with the terms and conditions of all
required insurance policies and all requirements of applicable governmental
authorities. Tenant shall be responsible or liable for all damages anywhere in
the Building or with respect to the Real Estate caused by any electrical
overload attributable to Tenant.

            (b) At all times, Tenant shall provide access for Landlord to trench
headers provided that Landlord's work shall not prevent the conduct of Tenant's
business and shall be conducted at such times and in a manner so as to minimize
disruption of Tenant's operations.

wear and tear excepted), installations, additions and improvements which may
have been made in, annexed or otherwise attached thereto, broom clean, and in
good condition and repair, ordinary wear and tear excepted, and except for
damage by fire or other casualty which Landlord is required to repair hereunder,

or any subtenant or occupant, which shall remain in or on the Demised Premises
after the termination of this Lease and the removal of such Tenant, subtenant or
occupant from the Demised Premises, may, at the option of Landlord and without
notice, be deemed to have been abandoned by such Tenant, subtenant occupant, and
may either be retained by Landlord as its property or be disposed of, without
accountability, in such manner as Landlord may see fit. Tenant shall reimburse
Landlord for any cost or expense incurred by Landlord in carrying out the
foregoing which obligation shall survive the Expiration Date. Landlord shall not
be responsible for any loss or damage occurring to any such property owned by
Tenant or any subtenant or occupant.

Regulations pursuant to this Lease so that more than eight (8) Holidays exist
(such additional Holidays being referred to as "Excess Holidays"), Tenant shall
not be charged for any excess use of building services during the period between
8:00 a.m. and 6:00 p.m. on any Excess Holiday unless Tenant is also treating the
Excess Holiday(s) as a business holiday. Payment for excess use of services
shall be deemed Rent and shall be paid to Landlord monthly, together with Base

herein). Tenant shall pay to Landlord, as a component of Rent, the sum of One
Dollar and Thirty-Five Cents ($1.35)/rentable sq. ft./yr. in advance on a
monthly basis together with Base Rent. This sum shall represent the cost of all
electricity furnished to Tenant at the Demised Premises during Business Hours,
other than for heating and air-conditioning, based on 5.5 watts/useable sq. ft.

            (b) If the Plans and Specifications submitted in connection with the
Tenant Work or any alterations or improvements undertaken by Tenant during the
Term anticipate extra electric usage based on either substantially greater needs
than 5.5 watts/useable sq. ft. or regular usage beyond the Building Business
Hours, the amount charged to Tenant as set forth in paragraph (a) above shall be
adjusted to reflect such additional usage.

            (c) The amount payable by Tenant as set forth in paragraph (a) above
may be adjusted when the rate charged Landlord by the local electric company is
modified between the execution of this Lease and the Commencement Date and

            (d) Subsequent to Tenant's having taken occupancy and commenced use
of the Demised Premises, Landlord or Tenant may cause a survey to be made by an
independent electrical engineer or other qualified person of the estimated use
of electricity on the Demised Premises (other than for heat and air
conditioning). The $1.35/rentable sq. ft./yr. charge set forth in paragraph (a)
above shall be adjusted not more frequently than annually to reflect the outcome
of this survey. The cost of preparing the survey shall be included in Building

permits. Tenant shall arrange with the utility company for such installation,
which shall be at Tenant's expense. Tenant shall pay for its electrical usage
based on metering to Landlord on a monthly basis together with Base Rent, at the
rate applicable to Landlord, in lieu of the charge set forth in paragraph (a)
above.

            (f) Landlord currently uses a certain utility company to provide
electricity service for the Real Estate (the "Current Electric Service
Provider"). Notwithstanding the foregoing, if permitted by applicable law,
Landlord shall have the right at any time and from time to time during the Term
of this Lease to either contract for services from a different company or
companies providing electricity service (each such company being referred to as
an "Alternate Service Provider") or continue to contract for service from the

                  (iii) The subtenant's or other user's occupancy of the Demised
Premises will cause excessive demands on the Real Estate.

                  (iv) Less than 90% of the rentable area of the Building is
rented.

            (d) Tenant shall remain primarily liable for all obligations of this
Lease in the event it sublets or assigns all or any portion of the Demised
Premises.

            (e) A subtenant or assignee shall not have the rights to renewal of
the Lease of the Demised Premises provided herein.

            (f) Any Excess Assignment Consideration (as defined below) or Excess
Sublease Rentals (as defined below) in connection with an assignment or sublease
permitted under this Lease shall be shared equally between Tenant and Landlord.
For purposes of this Section 10.01(f), (i) "Excess Assignment Consideration"

connection with such sublease (including but not limited to third party leasing
commissions, concessions, outside attorneys' fees and tenant improvements), ),
(B) the then remaining unamortized portion of the cost of the Tenant Work,
amortized on a straight-line basis over the term of this Lease, and (C) any
consideration paid to Tenant by the sublessee for. Tenant's furniture and
equipment in the Demised Premises (but not more than the fair market value of
such furniture and equipment); it being understood that if only a portion of the
Demised Premised are sublet, then only the portion of the space so sublet shall
be taken into account for purposes of such calculation.

            Section 10.02. Subordination:

            (a) Subject to Section 10.02(b) hereof, at Landlord's election, this
Lease shall be subordinate or superior to the lien of any present or future
mortgage irrespective of the time of recording of such mortgage. Landlord may
exercise such election by giving notice thereof to Tenant. At the election of
Landlord, this clause shall be self-operative and no further instrument shall be
required. Upon Landlord's request, at any time and from time to time (provided
that the Mortgagee shall have executed the agreement referenced in Section
10.02(b) hereof), Tenant shall (a) confirm in writing and in recordable form
that this Lease is so subordinate or so paramount to the lien of any mortgage
and/or (b) execute an instrument making this Lease so subordinate or so
paramount (as Landlord may elect) to the lien of any mortgage, in such form as
may be required by an applicable mortgagee. The exercise of any of the elections
provided in this Section shall not exhaust Landlord's right to elect differently
thereafter, from time to time.

            (b) Landlord shall obtain from any Mortgagee a non-disturbance
agreement in favor of the Tenant which recognizes this Lease and agrees not to
disturb Tenant's possession of the Demised Premises as provided in this Lease,
in each case for so long as the Tenant is not in default under this Lease, and
provided the Tenant agrees to attorn to the said Mortgagee in the event it comes
into possession of the premises.

            (c) Landlord shall endeavor to obtain the following provisions in
any such non-disturbance agreement: (i) such mortgagee or ground lessor shall
honor this Lease in accordance with its terms; (ii) such mortgagee or ground
lessor shall not name Tenant in any foreclosure proceedings; and (iii) such
mortgagee or ground lessor shall cause Landlord's obligations under this Lease
to be performed from and after the date of any foreclosure, purchase or
transfer.

            (d) Landlord shall have the right to assign Tenant's Rent payments
to any Mortgagee. Upon prior written notice from Landlord, Tenant shall make
payments directly to such assignee.

            (e) Landlord represents and warrants that as of the date hereof,
there is no mortgage on the Real Estate.

            Section 10.03. Attornment:

            If the Demised Premises, the Building or the Land are encumbered by
a Mortgage and such Mortgage is foreclosed, or if same are sold pursuant to such
foreclosure or by reason of a default under said Mortgage, (a) Tenant shall not
disaffirm this Lease or any of its obligations hereunder, and (b) at the request
of the applicable Mortgagee or purchaser at such foreclosure or sale, Tenant
shall attorn to such Mortgagee or purchaser.

            Section 10.04. Transfer of Landlord's Interest:


                                       20
<PAGE>
            The term "Landlord" as used in this Lease means only the owner or
the mortgagee in possession of the Demises Premises, the Building or the Real
Estate for the time being. In the event of any sale (including any
sale-leaseback) of the Demises Premises, the Building or the Real Estate,
Landlord shall be and hereby is entirely freed and relieved of all of its
covenants, obligations and liability hereunder, provided the transferee assumes
all of Landlord's obligations hereunder. This subsection shall be applicable to
each owner from time to time, and shall not be limited to the first owner of the
Demised Premises, the Building or the Real Estate.

            Section 10.05. Mortgagee's Rights:

            If Landlord shall notify Tenant that the Demised Premises, the
Building or the Land are encumbered by a Mortgage and in such notice set forth
the name and address of the Mortgagee thereof, then, notwithstanding anything to
the contrary contained herein, no notice intended for Landlord shall be deemed
properly given unless a copy thereof is simultaneously sent to such Mortgagee by
certified or registered mail, return receipt requested. If any Mortgagee shall
perform any obligation that Landlord is required to perform hereunder, such
performance by Mortgagee, insofar as Tenant is concerned, shall be deemed
performance on behalf of Landlord and shall be accepted by Tenant as if
performed by Landlord.

                            ARTICLE XI. COMMON AREA

            Section 11.01. Use of Common Area:

            During the Term, the following rights to use certain portions of the
Real Estate in common with Landlord and any designee of Landlord, subject to the
terms of this Lease and Landlord's Rules and Regulations, are hereby granted to
Tenant:

            (a) the non-exclusive right to permit its employees, agents and
invitees to use the Common Area as defined under 2.01; and

            (b) the non-exclusive right to permit its employees, agents and
invitees to use the entrance and exit ways designated by Landlord from time to
time for access to the Demised Premises from a public street or highway adjacent
to the Real Estate through the appropriate entrances and exits so designated.

            Section 11.02. Landlord's Rights:

            Notwithstanding anything to the contrary contained herein, Landlord
shall have the right:

            (a) to close all or any portion of the Common Area including the
Parking Area to such extent as may, in the opinion of Landlord's counsel, be
necessary to prevent a dedication thereof or the accrual of any rights of any
person or the public therein;

            (b) to close all or any portion of the Common Area;

            (c) to prohibit parking or passage of motor vehicles in areas
previously designated for such and to change the location of exclusively marked
parking spaces provided Landlord provides substitute parking, if required, and
provided that such action does not unreasonably interfere with Tenant's access
or ability to conduct business in the Demised Premises;

            (d) to temporarily close any of the Common Area for repair,
maintenance, alteration or improvements;


                                       21
<PAGE>
            (e) to build additions to the Building or erect additional buildings
on the Common Area or the Land;

            (f) to create paths, walks or other means of cross access through
the Land.

            Section 11.03. License Numbers:

            In order to restrict the use by Tenant's employees of areas
designated or which may be designated by Landlord as handicapped, reserved or
restricted Parking Areas, Tenant agrees that it will, at any time requested by
Landlord, furnish Landlord with the License numbers of any vehicle of Tenant and
Tenant's employees or agents.

            Section 11.04. Landlord's Obligation with Respect to Parking Area

            Throughout the Term, Landlord shall keep the Parking Area properly
paved and in good order and repair, properly drained and shall provide painted
stripes to designated parking spaces. After the end of a snowfall, Landlord will
commence to remove accumulated snow and ice from the Parking Area and diligently
prosecute the same to completion so that, to the extent practicable, the Parking
Area shall be reasonably free of snow and ice. Landlord may deposit accumulated
snow on such portions of the Common Area as may be necessary under the
circumstances. If any ice cannot be removed with reasonable effort on the part
of Landlord, it will be sufficient for Landlord to spread sand and other
abrasive substances over the ice.

                      ARTICLE XII. DESTRUCTION OR DAMAGE.

            Section 12.01. Rent Abatement:

            If the Demised Premises shall be partially damaged or destroyed by
fire or other casualty not attributable to the fault, negligence or misuse of
Tenant, its agents or employees, the Rent payable hereunder shall be abated to
the extent that the Demised Premises shall have been rendered untenantable and
for the period from the date of such damage or destruction to the date the
Demised Premises is rendered tenantable. Should tenant reoccupy a portion of the
Demised Premises during the period any restoration work is taking place and
prior to the date same is made completely tenantable, Rent allocable to such
portion shall be payable by Tenant from the date of such partial occupancy.

            Section 12.02. Option to Terminate:

            If the Building or the Demised Premises shall be damaged or
destroyed by fire or other casualty (in the former case, whether or not the
Demised Premises are damaged or destroyed) so as to require an expenditure in
Landlord's reasonable opinion of more than 40% of the full insurable value
(determined prior to the casualty) of the Building or Demised Premises as the
case may be, then in either such case, Landlord may terminate this Lease by
giving Tenant written notice within ninety (90) days after the date of the
casualty, specifying the date of termination of this Lease. In such event,
Tenant shall forthwith quit, surrender and vacate the premises without
prejudice, however, to Landlord's rights and remedies against Tenant (or any
rights or remedies which Tenant may have against Landlord which are expressly
set forth in this Lease) as of the date of termination or as to those rights
which survive such termination. In the event of termination, the Rent payable
hereunder shall be abated from the date of damage or destruction. If Landlord's
estimate (which estimate shall be given no later than thirty (30) days following
the date of the damage or destruction) of the time required to repair the
Demised Premises (so that Tenant can reasonably conduct its business therein)
exceeds twelve (12) months from the date of such damage or destruction, Tenant
shall have the right to terminate this Lease by giving written notice to
Landlord within thirty (30) days after receipt of the Landlord's estimate. If
Tenant exercises such termination right, the Lease shall terminate on the date
specified in the termination notice


                                       22
<PAGE>
(without prejudice, however, to Landlord's rights and remedies against Tenant
(or any rights or remedies which Tenant may have against Landlord which are
expressly set forth in this Lease) as of the date of termination or as to those
rights which survive such termination).

            Section 12.03. Landlord's Obligation to Rebuild:

            If all or any portion of the Demised Premises or access thereto is
damaged by fire or other casualty and if Landlord (or, to the extent provided in
Section 12.02 hereof, Tenant) has not elected to terminate this Lease, Landlord
shall, within a reasonable time after such occurrence, repair or rebuild the
Demised Premises, such portion or access thereto to its condition immediately
prior to the Commencement Date. Tenant may terminate this Lease by giving
written notice to Landlord, if Landlord has not commenced the required repairs
within one hundred twenty (120) days or has not restored and rebuilt the Demised
Premises as herein provided within twelve (12) months from the date of such
damage or destruction and such delay is due to Landlord's fault. Landlord shall
not be obligated to expend in such repair or rebuilding any sums greater than
the proceeds of any insurance policy carried by Landlord or for Landlord's
benefit.

            Section 12.04. Landlord's Liability:

            Landlord shall not be obligated to pay any damages, compensation or
claim for inconvenience, loss of business or annoyance arising from any
casualty, or repair or restoration of any portion of the Demised Premises or of
the Building pursuant to this Article.

            (a) Taking: The deprivation of or damage to the Demised Premises,

by a governmental authority of any power of eminent domain, condemnation, or the
purchase by purchaser under threat thereof.

            (b) Taking Date: With respect to any Taking, the date on which the
condemning authority or purchaser under threat shall have the right to
possession of the Demised Premises, the Building or the Land or any portion
thereof.

            (c) Award: The proceeds of any Taking, less all expense in
connection therewith, including reasonable attorneys' fees.

            Section 13.02. Taking of Demised Premises:

            (a) In the event of a Taking of the whole of the Building, Land or
Demised Premises, other than a Taking for temporary use, this Lease shall
automatically terminate as of the Taking Date.

            (b) In the event of a Taking of 40% of the Building, 40% of the Land
or 50% of the Demised Premises, Landlord, at its sole option, may terminate this
Lease by giving written notice to the other party anytime between the period
three (3) months prior to the Taking Date and three months after such date. The
termination of the Lease shall be effective three months after such notice is
received. In the event of a Taking of 50% of the Demised Premises or 50% of the
Building which in Tenant's reasonable judgment materially interferes with
Tenant's ability to conduct its business in the Demised Premises, or
substantially denies or interferes with Tenant's access to the Building or
Demised Premises, Tenant shall have the right to terminate this Lease by giving
Landlord written notice of its election


                                       23


<PAGE>

            If there is a Taking of the Demised Premises for temporary use, this
Lease shall continue in full force and effect, and Tenant shall continue to
comply with all the provisions thereof, except as such compliance shall be
rendered impossible or impracticable by reason of such Taking. Rent shall be
abated during the course of such Taking to the extent and for the period of time
that the Demised Premises shall have been rendered untenantable.

            Section 13.04. Disposition of Awards:

            All Awards shall belong to Landlord without any participation by
Tenant; provided, however, that Tenant shall be entitled to any identifiable
award for Tenant's furniture, fixtures, moving expenses and the unamortized
value of Tenant Work, in each case in connection with such Taking.

                        ARTICLE XIV. TENANT'S INSURANCE.

            Section 14.01. General Insurance:

            (a) At all times during the Term of this Lease, Tenant shall carry
and maintain, at Tenant's expense, the insurance required hereunder, in the
amounts specified in this Article or such other amounts and in form and
substance as Landlord may from time to time reasonably request, issued by an
insurance company reasonably satisfactory to Landlord. Upon the execution of
this Lease, and from time to time as requested by Landlord, Tenant shall deliver
to Landlord certificates of all insurance policies required to be carried
hereunder with evidence of payment of applicable premium. All policies shall
name Landlord and all mortgagees, as additional insureds.

            (b) Each policy so issued shall expressly provide: (i) that it may
not be cancelled for nonpayment, or for other reason without thirty (30) days'
advance written notice to Landlord; (ii) that the insurance company shall not
fail to renew the policy without thirty (30) days' advance written notice to
Landlord; (iii) that no material change may be made in the policy; and (iv) that
it is not subject to invalidation as to Landlord's interest by reason of any act
or omission of Tenant.

            (c) The term "insurance policy" shall include any extensions or
renewals of such insurance policy.

            (d) Landlord shall keep in force during the Term "all risk" casualty
insurance covering the Building in an amount not less than fifty percent (50%)
of the replacement value of the Building with such deductibles and with such
coverage exclusions as Landlord deems reasonable. Any insurance required by the
preceding sentence shall be (A) with Landlord's insurer so long as Landlord is
The Connell Company or an affiliate of The Connell Company; otherwise the
insurance shall be issued by a recognized and reputable insurance company and
(B) only required if and to the extent that such insurance is available to
owners of commercial office properties at commercially reasonable rates. Without
limiting the foregoing, Landlord shall maintain insurance coverage for the
Building and Land as it deems necessary, and Tenant shall not do or permit to be
done any act or thing upon the Real Estate which would (i) jeopardize or be in
conflict with fire insurance policies covering the Building and fixtures and
property on the Land, (ii) increase the rate of fire or other casualty insurance
applicable to the Real Estate to a rate higher than it otherwise would be for
general office use of the Building, or (iii) subject Landlord to any liability
or responsibility for injury to any person or persons or to property by reason
of any business or operation Tenant carries on upon the Real Estate.


          Section 14.02. Tenant Liability Insurance:

            Tenant shall provide on or before it enters the Demised Premises for
any reason and shall keep in force during the Term for the benefit of Landlord
and Tenant, liability insurance naming Landlord and any designee of Landlord as
additional insureds. The policy shall protect Landlord, Tenant and any designee
of Landlord against any liability occasioned by any occurrence on or about the
Demised Premises or any appurtenance thereto or arising from any of the items
indicated in Section 15.01 against which Tenant is required to indemnify
Landlord. Such policy is to be written in a combined single limit of at least
$3,000,000.00 for injury or death to one or more than one person arising from
any one occurrence and in the amount of $1,000,000.00 with respect to property
damages. In addition, Tenant shall maintain and provide a $10,000,000.00,
umbrella policy on terms Landlord specifies.

            Section 14.03. Tenant Fire Insurance:

            Tenant shall insure and keep its equipment, personal property and
all leasehold improvements benefiting the Demised Premises or elsewhere on the
Real Estate insured against damage by fire, water and other casualties and risks
covered by "All Risk" and extended coverage insurance. Landlord will not carry
insurance of any kind on Tenant's equipment or personal property, and, except as
provided by law or by reason of its fault or its breach of any of its
obligations hereunder, shall not be obligated to repair any damage thereto or
replace the same.

            Section 14.04. Tenant Worker's Compensation Insurance:

            Tenant shall maintain worker's compensation insurance insuring

            Tenant shall carry insurance against such other hazards and in such
amounts as may be customarily carried by tenants of similar properties, as
Landlord may reasonably require for its protection from time to time.

            Section 14.06. Waiver of Subrogation:

            Landlord and Tenant each hereby releases the other, its officers,
directors, employees and agents from liability or responsibility (to the other
or anyone claiming through or under them by way of subrogation or otherwise) for
any loss or damage to property covered by valid and collectible fire insurance
policy with standard extended coverage endorsement, even if such loss or damage
shall have been caused by the fault or negligence of the other party, or anyone
for, whom such party may be responsible to the extent of insurance proceeds.
Landlord and Tenant each agrees that any fire and extended coverage insurance
policies carried by each of them respectively and covering the Demised Premises
or their contents will include such a clause or endorsement.

            Section 14.07. Insurance Rate:

            If, as a result of (a) any act or omission by Tenant or violation of
any terms of this Lease; (b) the use to which Tenant has put Demised Premises;
or (c) Tenant's failure to comply with Landlord's insurance requirements,
Landlord's insurance rates applicable to the Real Estate are raised, Tenant
shall reimburse Landlord, on demand, for the increased cost of Landlord's
insurance premiums, which comprise part of Rent. For the purposes of this
Section, any finding or schedule of the fire insurance rating organization
having jurisdiction over the Real Estate shall be deemed to be conclusive.

            Section 14.08. Toxic and Hazardous Materials:


                                       25

products otherwise defined as hazardous, which products are used by Tenant with
due care and in accordance with the instructions of the product manufacturer and
otherwise in compliance with applicable law, in the reasonable and prudent
conduct of Tenant's business). Tenant will be solely responsible for and will
defend, indemnify and hold Indemnified Parties (as defined in Section 15.01(a)

existing prior to such storage, use, generation, manufacture, production,
release, discharge or disposal of toxic materials or Hazardous Materials.
Tenant's obligations under this Section will survive the termination of this
Lease.

and/or preservation of the environment), or hazardous materials or substances.

            (c) Landlord represents and warrants that, to the best of its
knowledge, as of the date hereof, there are no Hazardous Materials (other than

Estate. Landlord agrees that it will not use, generate, manufacture, produce,
store, release, discharge or dispose of Hazardous Materials in, on, under or
about the Demised Premises, the Building or Real Estate, other than in
compliance with applicable law.

            (d) Landlord will hold harmless, indemnify, and defend Tenant
Parties (as defined in Section 15.01(b) hereof) from and against all claims,

responsibilities, liabilities, payments, demands and expenses (including
reasonable attorneys' fees and disbursements) of any nature whatsoever to the
extent relating to or arising from the gross negligence or willful misconduct of
Landlord in connection with this Lease. Landlord shall defend any actions, suits
and proceedings which may be brought against any Tenant Party with respect to
the foregoing or in which they may be impleaded. Landlord shall pay, satisfy and
discharge any judgments, orders and decrees which may be recovered against any
Tenant Party in connection with the foregoing.

            (b) The rights to indemnification set forth in this Section 15.01
shall be in addition to and not in lieu of any other rights to indemnification
set forth in this Lease, and shall survive the Expiration Date or other
termination hereof. Landlord (on behalf of itself and any applicable Indemnified
Party) shall notify Tenant of any claims for which Landlord seeks
indemnification pursuant to this Section 15.01. Tenant (on behalf of itself and
any applicable Tenant Party) shall notify Landlord of any claims for which
Tenant seeks indemnification pursuant to this Section 15.01. Notwithstanding
anything to the contrary herein, any indemnification in this Lease is subject to
the waiver of subrogation provisions set forth in this Lease, to the extent any
such waiver of subrogation provision is applicable thereto.

            Section 15.02. Waiver and Release:

            Tenant hereby waives and releases all claims against Landlord with
respect to all matters for which Landlord has disclaimed liability pursuant to
the provisions of this Lease.

            (a) Neither Landlord nor any agent or employee of Landlord shall be
liable to Tenant for (i) any injury or damage to Tenant or to any other person
or (ii) any damage to, or loss (by theft or otherwise) of, any property of
Tenant or any other person, irrespective of the cause of such injury, damage, or
loss, except to the extent caused by or due to the willful misconduct or gross
negligence of Landlord, its agents or employees.

            (b) Landlord, and (in case Landlord shall be a joint venture,
partnership, tenancy-in-common, association or other form of joint ownership)
the members of any joint venture, partnership, tenancy-in-common, association or
other form of joint ownership shall have absolutely no personal liability with
respect to any provision of this Lease, or any obligation or liability arising
therefrom or in connection therewith. Tenant shall look solely to the equity of
the owner in the Real Estate or to any insurance which Landlord is obligated to
provided under the terms of this Lease for the satisfaction of any remedies of
Tenant in the event of a breach by Landlord of any of its obligations. Such
exculpation of liability shall be absolute and without any exception whatsoever.

            (c) All property (whether real, personal or mixed) at any time
located in or upon the Demised Premises shall be at the risk of Tenant only, and
Landlord shall not become liable for any damage to said property or to Tenant,
or to any other property, caused by water, leakage, steam, sewerage, gas or
odors or for any damage whatsoever done or occasioned by or from any boiler,
plumbing, gas, water, steam or other pipes, or any fixtures or equipment or
appurtenances whatsoever, or for any damage arising from any act or neglect or
arising by reason of the use of, or any defect in, the Demised Premises or any
of the fixtures, equipment or appurtenances therein contained, or by the Act or
neglect of any other person or caused in any other manner whatsoever or
occasioned by theft, Act of God, riot, strike or other labor difficulty, except
to the extent caused by or due to the willful misconduct or gross negligence of
Landlord, its agents or employees.

            (d) Except as otherwise expressly provided herein, this Lease and
the obligations of Tenant hereunder shall be in no way affected, impaired or
excused because Landlord is unable to fulfill, or is delayed in fulfilling, any
of its obligations under this Lease.

                        ARTICLE XVI. DEFAULT; REMEDIES.

            Section 16.01. Default:

            Each of the following shall constitute an Event of Default:

            (a) the filing by tenant of a bankruptcy petition, or the
            commencement of a proceeding under the insolvency laws of any State
            naming Tenant as the debtor;

            (b) the filing by anyone other than Tenant of a bankruptcy petition
            or a proceeding under the insolvency laws of any State naming Tenant
            as the debtor, which case shall not have been discharged within 30
            days of the commencement thereof;

            (c) the making by Tenant of any assignment for the benefit of
            creditors or any other arrangement involving all or substantially
            all of its assets under any state statute;

            (d) the appointment of a receiver or trustee for the Tenant or for
            all or any portion of the property of Tenant in any proceeding,
            which receivership shall not have been set aside within 30 days of
            such appointment;

            (e) the failure of Tenant to pay (i) any Base Rent when the same
            shall become due and payable; provided, however, that, with respect
            to the first one (1) time in any twelve month period during the Term
            in which Tenant fails to pay Base Rent when due and payable, such
            failure to pay shall not constitute an Event of Default under this
            clause (e) until such failure to


                                       28
<PAGE>
            pay continues for a period of five (5) days after written notice
            thereof from Landlord to Tenant, or (ii) any other Rent or other
            charge required to be paid by Tenant hereunder (other than Base
            Rent, in which case clause (i) is applicable) when the same shall
            become due and payable and continues to be unpaid for a period of
            five (5) days after written notice thereof from Landlord to Tenant;

            (f) the Letter of Credit shall for any reason whatsoever cease to be
            in full force and effect (or Tenant shall otherwise be in breach of
            Section 1.04 hereof), or the Letter of Credit Provider (or any party
            on behalf of the Letter of Credit Provider) shall contest the
            obligation to pay under the Letter of Credit in accordance with its
            terms; and

            (g) the failure by Tenant to perform or observe any requirement of
            this Lease not specifically referred to in this Section, and such
            failure continuing for twenty (20) days after written notice from
            Landlord to Tenant specifying the items in default; provided
            however, that if the failure requires more than twenty (20) days to
            cure, is capable of being cured, and so long as Tenant is
            prosecuting the cure to completion with due diligence, Tenant shall
            be permitted an additional thirty (30) days to cure before such
            failure constitutes and Event of Default.

            Section 16.02. Landlord's Remedy:

            At any time after the occurrence of an Event of Default, Landlord
may give written notice to Tenant specifying such Event(s) of Default and
stating that the Lease and Term shall terminate five (5) days after the giving
of such written notice. At the expiration of such five days, this Lease and the
Term and all of the right, title and interest of Tenant hereunder shall wholly
cease and expire, and Tenant shall quit and surrender the Demised Premises to
Landlord. Notwithstanding such termination, surrender, and the expiration of
Tenant's right, title, and interest, Tenant's liability and responsibility under
all of the provisions of this Lease shall continue.

            Section 16.03. Landlord's Re-Entry

            If this Lease shall be terminated as provided in Section 16.02,
above, Landlord, or its agents or employees, may re-enter the Demised Premises
at any time and remove therefrom Tenant, Tenant's Agents, and any subtenants,
licensees, concessionaires or invitees, together with any of its or their
property, either by summary dispossession proceedings or by any suitable action
or proceeding at law or otherwise. In the event of such termination, Landlord
may repossess and enjoy the Demised Premises. Landlord shall be entitled to the
benefits of all provisions of law respecting the speedy recovery of lands and
tenements, or proceedings in forcible entry and detainer. Landlord shall not be
liable in any way in connection with any action it takes pursuant to the
foregoing. Notwithstanding any such re-entry, repossession, dispossession or
removal, Tenant's liability and responsibility under all of the provisions of
this Lease shall continue.

            Section 16.04. Landlord's Additional Remedies:

(a) In case of re-entry, repossession or termination of this Lease, whether the
same is the result of the institution of summary or other proceedings, Tenant
shall remain liable (in addition to accrued liabilities) to the extent legally
permissible for: (i) the Rent, and all other charges provided for herein until
the date this Lease would have expired had such termination, re-entry or
repossession not occurred; and all expenses which Landlord may have incurred in
re-entering the Demised Premises, repossessing the same; making good any Event
of Default; painting, altering or dividing the Demised Premises; combining or
placing the same in proper repair; protecting and preserving the same by placing
therein watchmen and caretakers; re-letting the same (including attorneys' fees
and disbursements,


                                       29
<PAGE>
marshall's fees, brokerage fees, in so doing); and any expenses which Landlord
may incur during the occupancy of any new tenant; less (ii) the net proceeds of
any re-letting. Tenant agrees to pay to Landlord the difference between items
(1) and (ii) hereinabove with respect to each month, at the end of such month.
Any suit brought by Landlord to enforce collection of such difference for any
one month shall not prejudice Landlord's right to enforce the collection of any
difference for any subsequent month. In addition to the foregoing, Tenant shall
pay to Landlord such sums as the court may adjudge reasonable as attorneys' fees
with respect to any successful lawsuit or action instituted by Landlord to
enforce the provisions hereof.

            (b) Landlord may re-lease the whole or any part of the Demised
Premises for the whole of the unexpired period of this Lease, or longer, or from
time to time for shorter periods, for any rental then obtainable, giving such
concessions of rent and making such special repairs, alterations, decorations
and paintings for any new tenant as it may in its sole and absolute discretion
deem advisable and may collect and receive the rents therefor. Landlord shall
use reasonable efforts to re-lease or to attempt to re-let the Demised Premises
on reasonable terms to mitigate its damage.

            Section 16.05. Agreed Final Damages:

In the event of the occurrence of an Event of Default, if Landlord so elects,
Tenant shall pay Landlord, on demand, as liquidated and agreed final damages,
the net present value of all Base Rent which would have been payable by Tenant
from the date of such demand to the date when this Lease would have expired if
it had not been terminated as aforesaid. Such net present value shall be
computed using a discount rate equal to the federal funds rate in effect at such
time. Upon payment of such liquidated and agreed final damages, Tenant shall be
under no further liability with respect to the period after the date of such
demand.

            Section 16.06. Waiver of Right of Redemption:

            Tenant hereby expressly waives (to the extent legally permissible),
for itself and all persons claiming by, through, or under it, any right of
redemption or for the restoration of the operation of this Lease under any
present or future law in case Tenant shall be dispossessed for any cause, or in
case Landlord shall obtain possession of the Demised Premises as herein
provided.

            Section 16.07. Landlord's Right to Perform for Account of Tenant;
Letter of Credit:

            If an Event of Default shall occur hereunder, Landlord may, at any
time, cure said Event of Default for the account and at the expense of Tenant.
Tenant shall pay, on demand, to Landlord, with interest as required by Section
20.09 hereof, the amount so paid, expended, or incurred by Landlord and any
expense of Landlord, including reasonable attorneys' fees, incurred in
connection with such Event of Default; and all of the same shall be deemed to be
Additional Rent. If an Event of Default shall occur hereunder, without limiting
any other remedy Landlord otherwise may have under this Lease, Landlord shall be
entitled to draw upon all or any portion of the Letter of Credit in order to
satisfy any obligations of Tenant owing under this Lease.

            Section 16.08. Additional Remedies, Waivers, etc.:

            With respect to the rights and remedies of and waivers by Landlord:

            (a) The rights and remedies of Landlord set forth herein shall be in
addition to any other right and remedy now and hereafter provided by law. All
such rights and remedies shall be cumulative and not exclusive of each other.
Landlord may exercise such rights and remedies at such times, in such order, to
such extent, and as often as Landlord deems advisable without regard to whether
the exercise of one right or remedy proceeds, concurs with or succeeds the
exercise of another.


                                       30
<PAGE>
            (b) A single or partial exercise of a right or remedy shall not
preclude (i) a further exercise thereof, or (ii) the exercise of another right
or remedy, from time to time.

            (c) No delay or omission by Landlord in exercising a right or remedy
shall exhaust or impair the same or constitute a waiver of, or acquiescence to
an Event of Default.

            (d) No waiver of an Event of Default shall extend to or affect any
other Event of Default or impair any right or remedy with respect thereto.

            (e) No action or inaction by Landlord shall constitute a waiver of
an Event of Default.

            (f) No waiver of an Event of Default shall be effective unless it is
in writing and signed by Landlord.

(c) whether or not, to Tenant's knowledge, there are then existing set-offs or
defenses against the enforcement of any right or remedy of Landlord, or any duty

to which any Rent or other charges have been paid in advance; and (e) such other
factual matters relating to this Lease as may be reasonably requested by

forth such modification); (b) whether or not, to Landlord's knowledge, Tenant is
in default under the Lease; and (c) such other factual matters relating to this
Lease as may be reasonably requested by Tenant.

                         ARTICLE XVIII. RIGHT OF ACCESS

charges and expenses provided for herein in a timely manner as and when due,

all of the other provisions hereof, Tenant shall, at all times during


                                       31
<PAGE>
the Term, peaceably and quietly have, hold and enjoy the Demised Premises,

            party to cause such action to be taken; and

                  (ii) Any provision which requires any party not to take any
            particular action shall be deemed to require the party not to permit

            This Lease shall survive the expiration of the Term to the extent
necessary that any term, covenant or condition of this Lease requires the

after the termination of the Lease. Such survival shall be to the extent
reasonably necessary to fulfill the intent thereof, or if specified, to the
extent of such specification, as same is reasonably necessary to perform the
obligations and/or forbearance of an act set forth in such term, covenant or
condition.

            Section 20.06. Successors and Assigns:

            Subject to the provisions hereof, this Lease shall bind and inure to
the benefit of the parties and their respective successors, representatives,

            Section 20.08. Tenant at Sufferance:

            If Tenant shall remain in possession of the Demised Premises after
the end of the Term (including if the Demised Premises have not been surrendered
in accordance with the terms of this Lease), such holding over shall cause the
Tenant to be deemed a tenant-at-sufferance, subject to all of the provisions,
conditions and obligations of this Lease, except that the Rent to be charged
Tenant during such hold over period shall be (i) during the first thirty (30)
days of such hold over period, 150% of the monthly Rent in effect for the last
month of the Term or any renewal periods, and (ii) during any period thereafter,
two times the monthly Rent in effect for the last month of the Term or any
renewal periods. Any acceptance of hold over Rent by Landlord shall not be
deemed a waiver of any rights or remedies available to Landlord arising out of
Tenant's failure to have vacated the Demised Premises upon the end of the Term,
or an acquiescence to Tenant's tenant-at-sufferance period.

            Section 20.09. Interest:

            Any payment required to be made by Tenant under the provisions of

Landlord on demand with interest thereon at three (3%) percent over the rate
designated by the Bank of New York, New York (or its successor) from time to
time as the prime rate, but not to exceed the highest legal rate, computed from
the date said sum became due to and including the date of payment thereof to
Landlord.

            Section 20.10. Late Charge:

payments, Tenant, at Landlord's option, shall pay a "late charge" of five (5%)
percent of the amount due when any payment of Rent hereunder is received by
Landlord more than ten (10) days after the due date thereof. It is understood
and agreed that this charge is for additional expense incurred by Landlord,
shall not be considered interest, and shall be due in addition to the interest
required under Section 20.09 hereof.

            Section 20.11. Non-Waiver:

            The failure of Landlord to insist upon strict performance of any
covenants or conditions of this Lease or Landlord's failure to exercise any
option herein conferred in any one or more instances shall not be construed as a
waiver or relinquishment of any such covenants, conditions or options, but the
same shall be and remain in full force and effect. If Landlord pursues any
remedy granted by the terms of this Lease or pursuant to applicable law, it
shall not be construed as a waiver or relinquishment of any other remedy
afforded thereby.

            Section 20.12. Broker:

            Each party represents that there was no broker other than Cushman &
Wakefield of New Jersey, Inc. (the "Broker") responsible for bringing about or

Real Estate as a result of any Tenant Work or any additions, alterations,
repairs, installations, improvements or any other work or act of Tenant, Tenant
shall discharge or bond same within twenty days from the date of filing of the
lien. If Tenant shall fail to discharge or bond the lien, Landlord may bond or
pay the lien or claim for the account of Tenant without inquiring into the
validity of the lien or claim and Tenant shall reimburse Landlord upon demand.

                      ARTICLE XXI. ENVIRONMENTAL MATTERS.

            Section 21.01. Industrial Site Recovery Act:

            (a) Tenant represents and warrants that it is not an "Industrial
Establishment" as that term is defined in the Industrial Site Recovery Act,
formerly known as the Environmental Cleanup Responsibility Act, N.J.S.A.
13:1K-6 et seq., as same may be amended from time to time (together with
all rules, regulations, ordinances, opinions, orders and directives issued or
promulgated pursuant-to or in connection with said Act by the New Jersey
Department of Environmental-Protection ("DEP"), or any subdivision or bureau
thereof or any other governmental or quasi-governmental agency, authority or
body having jurisdiction thereof, referred to herein as the "Act" or "ISRA").
Tenant shall not do or suffer anything that will cause it to become an
Industrial Establishment under the Act during the Term of this Lease. Landlord
may from time to time require Tenant at Tenant's sole expense to provide proof
satisfactory to Landlord that Tenant is not an Industrial Establishment. In the
event that Tenant now is or hereafter becomes an Industrial Establishment or is
required by the DEP, Tenant shall comply with all conditions as set forth in
subparagraphs (b) and (d) of this Section 21.01.

            (b) Tenant agrees that it shall, at its sole cost and expense,
fulfill, observe and comply with all of the terms and provisions of the Act to
the extent in any way applicable to Tenant (including Tenant's use of the
Demised Premises or Real Estate), or Tenant's activities (even if the Act
applies to an owner of property). Without limiting the foregoing, upon
Landlord's reasonable request therefor, and in all events no later than sixty
(60) days prior to "closing, terminating or transferring operations" (as said
terms are defined and used in the Act) out of the Demised Premises (it being
agreed that such 60 day time limit may be extended, in Landlord's discretion, if
such time limit is not reasonable in light of the DEP's required response time),
Tenant at its sole cost and expense, shall provide Landlord with a true copy of:

                  (i) a letter of non-applicability from DEP (or such other
            agency or body which shall then have jurisdiction over ISRA matters)
            in form satisfactory to Landlord's counsel, stating that ISRA does
            not apply to Tenant, Tenant's use and occupancy of the Demised
            Premises and to the closing, terminating or transferring of
            operations at the Demised Premises; or


                                       36
<PAGE>
                  (ii) a Negative Declaration (as said term is defined in ISRA)
            duly approved by DEP or such other agency or body then having
            jurisdiction over ISRA matters; or

                  (iii) a Cleanup Plan (as said term is defined in ISRA) duly
            approved by DEP (or such other agency or body which shall then have
            jurisdiction over ISRA matters), the intent of which will be to
            obtain from the DEP a "No Further Action" ("NFA") determination with
            respect to the Demised Premises.

            (c) Nothing in this Section shall be construed as limiting Tenant's
obligation to comply with ISRA.

            (d) In the event Tenant complies with paragraph (b) (iii) of this
Section by obtaining an approved Cleanup Plan, Tenant agrees that it shall, at
its sole cost and expense:

                  (i) post any financial guarantee or other bond required to
            secure implementation and completion of such Cleanup Plan; and

                  (ii) promptly and diligently implement and prosecute to
            completion said Cleanup Plan by obtaining an NFA determination, in
            accordance with the schedules contained therein or as may otherwise
            be ordered or directed by DEP or such other agency or body which
            shall then have jurisdiction over such Cleanup Plan. Tenant
            expressly understands, acknowledges and agrees that Tenant's
            compliance with the provisions of subparagraphs (b) and (d) may
            require Tenant to expend funds or do acts after the expiration or
            termination of the Lease Term and Tenant shall not be excused
            therefrom.

            (e) Within ten (10) days after a written request by Landlord or any
mortgagee of Landlord (or sooner, if required by the DEP) and, in any event, on
each anniversary of the Commencement Date, Tenant shall deliver to Landlord and
Landlord's Mortgagee, if any, a duly executed and acknowledged affidavit of
Tenant's chief executive officer, certifying:

                  (i) the proper four digit Standard Industrial Classification
            number relating to Tenant's then current use of the Demised Premises
            (Standard Industrial Classification Number to be obtained by
            reference to the then current Standard Industrial Classification
            Manual prepared and published by the Executive Office of the
            President, Office of Management and Budget or the successor to such
            publication); and

                  (ii) (A) that Tenant's then current use of the Demised
            Premises does not involve the generation, manufacture, refining,
            transportation, treatment, storage, handling or disposal of
            hazardous substances or waste (as hazardous substances and hazardous
            waste are defined in ISRA) on site, above ground or below ground
            (all of the foregoing are hereinafter collectively referred to as
            the "Presence of Hazardous Substances"), or, (B) that Tenant's then
            current use does involve the Presence of Hazardous Substances, in
            which event, said affidavit shall describe in complete detail that
            portion of Tenant's operations which involves the Presence of
            Hazardous Substances. Such description shall, inter alia, identify
            each hazardous substance and describe the manner in which Tenant
            generated, handled, manufactured, refined, transported, treated,
            stored and/or disposed of same. Tenant shall supply Landlord and
            Landlord's mortgagee, if any,


                                       37
<PAGE>
            with such additional information relating to the Presence of
            Hazardous Substances as Landlord or Landlord's mortgagee requests.

            (f) Without limiting the foregoing, Tenant agrees:

                  (i) at its sole cost and expense, to promptly discharge and
            remove any lien or encumbrance against the Demised Premises, the
            Building, the Real Estate or any other property owned or controlled,
            in whole or in part, by Tenant imposed due to Tenant's failure to
            comply with ISRA, and

                  (ii) to defend, indemnify and hold Landlord harmless from and
            against any and all liability, penalty, loss, expenses, damages,
            costs, claims, causes of action, judgments and/or the like, of
            whatever nature, including but not limited to attorneys' fees and
            disbursements and other costs of litigation or preparation therefor,
            to the extent such costs arise from or in connection with Tenant's
            failure or inability, for any reason whatsoever, to observe or
            comply with ISRA and/or the provisions of this Section 21.01.

            Section 21.02. Spill Act:

            (a) Tenant agrees that it shall, at its sole cost and expense,
observe, comply and fulfill all of the terms and provisions of the Spill
Compensation and Control Act, N.J.S.A. 58:10-23.11 et. seq., as the same may be
amended from time to time and all rules, regulations, ordinances, opinions,
orders and directives issued or promulgated pursuant to or in connection with
said Act by DEP, any subdivision or bureau thereof or governmental or
quasi-governmental agency or body having jurisdiction thereof. (Said act and all
said rules, regulations, ordinances, opinions, orders and directives are
hereinafter in this Section 21.02 collectively referred to as "Spill Act"), in
each case to the extent in any way applicable to Tenant (including Tenant's use
of the Demised Premises or Real Estate), or Tenant's activities (even if the Act
applies to an owner of property).

            (b) Without limiting the foregoing, Tenant agrees:

                  (i) that it shall not do, omit to do or suffer the commission
            or omission of any act which is prohibited by or may result in any
            liability under the Spill Act, including without limitation the
            discharge of petroleum products or other hazardous substances (as
            said terms are defined in the Spill Act); and

                  (ii) whenever the Spill Act requires the "owner or operator"
            to do any act, Tenant shall do such act and fulfill, all such
            obligations at its sole cost and expense, it being the intention of
            the parties hereto that Landlord shall be free of all expense and
            obligations arising from or in connection with compliance with the
            Spill Act.

            (c) Without limiting the foregoing, Tenant agrees:

                  (i) at its sole cost and expense, to promptly discharge and
            remove any lien or any encumbrance against the Demised Premises, the
            Building, the Real Estate or any other property owned or controlled,
            in whole or in part, by Tenant, imposed by Tenant's failure to
            comply with the Spill Act; and


                                       38
<PAGE>
                  (ii) to defend, indemnify and hold Landlord harmless from and
            against any and all liabilities, penalties, losses, expenses,
            damages, costs, claims, causes of action, judgments, suits and/or
            the like, of whatever nature, (including but not limited to
            attorneys' fees and other expenses of litigation or preparation
            therefor) which may at any time be imposed on, incurred by or
            asserted against any Indemnified Party and which in any way relate
            to or arise from or in connection with Tenant's failure or
            inability, for any reason whatsoever, to observe or comply with the
            Spill Act and/or the provisions of this Section 21.02.

            Section 21.03. Other Environmental Laws:

            Without limiting any of its other obligations hereunder, Tenant
agrees that it shall, at its sole cost and expense, promptly comply and keep
continually in full compliance with all federal, state and local laws,
ordinances, rules, regulations and requirements relating to air, ground and
water pollution and protection and/or preservation of the environment.

            Section 21.04. Survival of Environmental. Terms and Conditions.

            Tenant agrees that each and every provision of this Article XXI
shall survive the termination of this Lease. The parties hereto expressly
acknowledge and agree that Landlord would not enter into this Lease but for the
provisions of this Article XXI and the aforesaid survival thereof.

                               TENANT WORKLETTER

            The Connell Company (subject to Section 10.04 of the Lease,
"Landlord") and Tenant are simultaneously executing a lease of the space
mentioned therein (the "Demised Premises"). To induce Tenant to enter into the
Lease (which is hereby incorporated by reference to the extent that the
provisions of this agreement apply thereto) and in consideration of the
covenants hereinafter contained, Landlord and Tenant mutually agree as follows:

1.    All terms defined in the Lease shall have the same meaning when used
      herein. The term "Usable Square Feet" shall refer to the square footage of
      the floor of the Demised Premises computed by measuring the area enclosed
      by: the finished surface of the office side of corridor and other
      permanent walls; the dominant portion or a major vertical penetration; and
      the center of partitions that separate the area being measured from
      adjoining office areas, store areas and/or Building Common Areas. No
      deductions shall be made for columns and projections necessary to the
      Building, and the above computation shall be made as if alcoves, recessed
      entrances or similar deviations from the corridor line were not present.

2.    Landlord shall not provide Tenant with any allowance against the cost of
      Tenant Work requested by Tenant in the Building; it being understood that
      Tenant shall be responsible for the full cost of any Tenant Work.

      design drawings, layouts and material specifications for the Demised
      Premises; (ii) an estimate of the total cost of Tenant Work; (iii) all
      working, finished, detailed construction drawings and specifications for
      the Tenant Work and any revisions thereto, all to be satisfactory to
      Tenant and in compliance with all applicable building codes and all other
      applicable laws and regulations. A copy of the foregoing shall be
      submitted to Landlord for general review and consent (which consent will
      not be unreasonably withheld, conditioned or delayed), but Tenant shall
      remain responsible for compliance with all applicable building codes and
      any other applicable laws and regulations. All Tenant Work will be
      completed in accordance with these approved drawings and specifications
      and all such work will be in accordance with applicable building codes and
      any other applicable laws and regulations.

4.    (a)   Subject to subparagraph (b) below and the other provisions hereof,
            Tenant shall have the right to perform its Tenant Work, provided
            that the Tenant uses a first-class union general contractor. Said
            contractor must use the initial Building subcontractors for each of
            the mechanical, electrical and sprinkler work so as to maintain the
            integrity of said systems.

      (b)   Tenant will obtain all permits and arrange for all inspections
            required for occupancy, in connection with all Tenant Work. The cost
            of all such permits and inspections shall be included in determining
            the cost of Tenant Work.
