  • Commercial Lease. Start a state-specific lease for the rental of commercial property. Specify the term and rent due, as well as whether the landlord or tenant is responsible for property taxes, insurance, and maintenance and repairs.
  • Commercial Sublease. When a tenant vacates commercial property before the lease term has expired, it may be able to rent the premises to a third party. The tenant would be the sublessor and the third party would be the sublessee. Besides preparing a sublease, both parties will want to review the provisions for assignment or subletting in the original lease agreement between the landlord and the sublessor.
  • Sublease Agreement. Tenants of residential property should prepare a sublease agreement if they are seeking to sublease a room or the entire apartment or house to a third party. All parties should review the original lease agreement to see if there are any restrictions on subletting or assigning the premises.
  • Triple Net Lease. Triple net leases are a type of commercial leases where the tenant has to pay for property taxes, insurance, utilities, and maintenance, in addition to the monthly rent.
  • Office Space Lease. When renting an office space, tenants should understand the amount of the rent and duration of the lease. Other important terms include whether the space can be subleased, which parties are responsible for maintenance, and whether any furniture and furnishings will be provided.

PARAGRAPH 1 TERM: The term of this Lease shall be as shown in Item 4 of the
Basic Lease Provisions. The Lease shall commence on the Commencement Date as
shown in Item 8 of the Basic Lease Provisions, or upon such earlier date as
Tenant takes possession or commences use of the Premises for any purpose,
excluding construction. Such date of commencement, hereinafter the "COMMENCEMENT
DATE," and the date of expiration, hereinafter the "EXPIRATION DATE," shall be
confirmed by Landlord by means of a "COMMENCEMENT DATE MEMORANDUM" in form
substantially similar to Exhibit "C."

PARAGRAPH 2 BASIC ANNUAL RENT: (A) Tenant agrees to pay as Basic Annual Rent for
the Premises the sum or sums shown in Item 6 of the Basic Lease Provisions. The
Basic Annual Rent shall be payable in U.S. currency in equal monthly
installments, hereinafter sometimes referred to as "BASIC MONTHLY RENTAL
INSTALLMENTS," in advance and without notice, deduction, offset, or abatement
except as otherwise provided herein. Basic Monthly Rental Installments shall be
in the sum or sums shown in Item 7 of the Basic Lease Provisions. Basic Annual
Rent shall commence on the Commencement Date and continue on the first day of
each calendar month thereafter except the first Basic Monthly Rental Installment
shall be paid at execution hereof. The Basic Monthly Rental Installment for any
partial month during the term hereof shall be prorated in the proportion that
the number of days this Lease is in effect during such partial month bears to
the number of days in that calendar month, and such Basic Monthly Rental
Installment shall be paid at the commencement of such partial month.

(B)      In addition to the Basic Annual Rent stipulated herein, Tenant
covenants and agrees to pay in U.S. currency, without deduction, offset, or
abatement except as otherwise provided herein to Landlord as additional rent,
hereinafter "ADDITIONAL RENT," all other sums and charges which are to be paid
by Tenant pursuant to the terms of this Lease. Except as otherwise provided in
this Lease, Additional Rent shall be due and payable on the first day of the
month following the date on which Tenant is given notice that Additional Rent is
due.

(C)      The Basic Annual Rent plus Additional Rent are sometimes collectively
referred to as "RENT."

PARAGRAPH 3 ADDITIONAL RENT FOR TAXES AND OPERATING EXPENSES, ETC.: (A)
Commencing with the first anniversary of the Commencement Date, Tenant agrees to
pay as items of Additional Rent for the Premises, Tenant's "Percentage Share"
(being the percentage indicated in Item 3 of Basic Lease Provisions) of all
increases in "Project Operating Expenses" and "Project Property Taxes" over the
Base Year shown in Item 13 of the Basic Lease Provisions incurred by Landlord in
the operation of the Project. For purposes of this paragraph, during each year
actual occupancy of the Building is less than one hundred (100%) percent,
Landlord will adjust the costs of all Project Operating Expenses to assume one
hundred (100%) percent occupancy of the Building and Landlord will adjust
Project Property Taxes to reflect assumed standard tenant improvements for one
hundred (100%) percent occupancy.

(B)      The items of Additional Rent contemplated under subparagraph 3(A) shall
be determined in accordance with the following procedures:

         (i)      Each December during the term hereof or as soon thereafter as
                  practical, Landlord shall give Tenant written notice of
                  Landlord's reasonable estimate of any amounts payable under
                  subparagraph 3(A) above for the ensuing calendar year. On or
                  before the first day of each month during the ensuing calendar
                  year, Tenant shall pay Landlord without further notice
                  one-twelfth (l/12) of such estimated amounts, provided that if
                  such notice is not given in December, Tenant shall continue to
                  pay

                  on the basis of the then applicable rental until the month
                  after such notice is given. If at any time or times it appears
                  to Landlord that the increased amounts payable under
                  subparagraph 3(A) for the current calendar year will exceed
                  its estimate, Landlord may, by notice to Tenant, revise its
                  estimate for such year. Subsequent payments by Tenant for such
                  year shall be based upon such revised estimate.

         (ii)     Within 90 (ninety) days after the close of each calendar year
                  or as soon thereafter as is practical, Landlord shall deliver
                  to Tenant a statement of the annual adjustment of those
                  Additional Rent items made pursuant to subparagraph 3(A) for
                  such calendar year. If on the basis of such statement Tenant
                  owes an amount that is less than the estimated payments for
                  such calendar year previously made by Tenant, Landlord shall
                  refund or credit such excess to Tenant. If on the basis of
                  such statement Tenant owes an amount that is more than the
                  estimated payments for such calendar year previously made by
                  Tenant, Tenant shall pay the deficiency to Landlord within 30
                  (thirty) days after delivery of the statement.

         (iii)    The Additional Rent or any credit or refund due Tenant due
                  under the terms and conditions of this Paragraph 3 shall
                  survive termination of this Lease, shall be payable by Tenant
                  without any setoff or deduction except as otherwise expressly
                  provided in this Lease, and shall be computed by Landlord on a
                  prorated basis for any period less than a full calendar year.

                  any capital improvements made to the Project by Landlord that
                  reduce operating expenses (but only to the extent of the
                  annual savings) or that are required under any governmental
                  law or regulation not previously applicable to the Project or

                  cost shall be amortized over such reasonable periods as
                  Landlord shall determine with a return on capital at the then

                  Project because of Tenant's acts

         (ii)     The term "Project Property Taxes" as used herein shall include
                  all real estate taxes or personal property taxes and other
                  taxes, charges and assessments, unforeseen as well as
                  foreseen, which are levied with respect to the Project and any
                  improvements, fixtures and equipment and other property of
                  Landlord, real or personal, located in the Building or on the
                  Project and used in connection with the operation of the
                  Project for each calendar year and shall include any tax,
                  surcharge or assessment which shall be levied in addition to

                  than taxes covered in Paragraph 11, and shall also include any
                  rental, excise, sales, transaction, privilege, or other tax or
                  levy, however denominated, imposed upon or measured by the
                  rental reserved hereunder or on Landlord's business of leasing
                  the Premises and Project, excepting only net income taxes.
                  Project Property Taxes shall be based upon the fully assessed
                  value of the fully completed Building including standard
                  tenant improvements, driveways, and other common areas of the
                  Building and Project. In the event tax assessment is not
                  detailed, sufficiently or, in the event either party shall
                  dispute the tax assessor's determination of full assessment
                  value, then Landlord and Tenant shall look to the following
                  two alternatives in the order given to determine assessed
                  value: (i) notes and records of tax assessor and (ii) any
                  reasonable method upon which the parties may agree.
                  Notwithstanding the provisions above, Project Property Taxes
                  exclude: (1) franchise gift, transfer, excise, capital stock,
                  estate, succession, or inheritance taxes, and (2) penalties or
                  interest for late payment of Project Property Taxes, and

(D)      Tenant shall have ninety (90) days after receiving the statement
referred to in subparagraph 3(B)(ii) to audit Landlord's books and records at
Landlord's offices. Unless Tenant takes written exception to any item in the
statement referred to in subparagraph 3(B)(ii) within ninety (90) days after the
furnishing of the statement, such statement shall be considered as final and
accepted by Tenant. Any amount due Landlord as shown on any such statement shall
be paid by Tenant within thirty (30) days after it is furnished to Tenant. If
Tenant shall dispute in writing any specific item or items in the statement of
Project Operating Expenses and Project Property Taxes, and such dispute is not
resolved between Landlord and Tenant within sixty (60) days after the date the
statement was rendered, either party may, during the thirty (30) days next
following the expiration of the sixty (60) days, refer such disputed item or
items to an independent certified public accountant selected by Landlord, for a
determination which shall be final, conclusive and binding upon Landlord and
Tenant. Tenant agrees to pay all costs involved in such determination unless it
is determined that Landlord's original calculation of both Project Property
Taxes and Project

                                       -8-


<PAGE>   11

Operating Expenses was in error, in Landlord's favor, by more than five (5%)
percent. Pending the determination of any dispute with respect to the statement
submitted by Landlord, Tenant shall pay when due the sums shown as due on such
statement. If it shall be determined that any portion of such sums were not
properly chargeable to Tenant, then Landlord shall credit or refund the
appropriate sum to Tenant.

(E)     As one of the items of Additional Rent, payable monthly, Tenant shall
also pay to Landlord the full cost of Tenant's consumption of electricity
(including heating and air-conditioning installed for a particular use by
Tenant), as reasonably determined from time to time by Landlord through
proration, engineering survey by Landlord's electric rate consultant, or other
reasonable method. In the event Landlord meters or submeters Tenant's
electricity usage, Tenant shall pay Tenant's share of any surcharge, "peak-hour"
premium or other similar additional charge. The initial estimated monthly
electricity charge for the Premises shall be as shown in Item 5 of the Basic
Lease Provisions. Commencing on Commencement Date Tenant shall also pay Landlord
any increase in the cost of electricity to the Premises based upon increases in
the billing rate after the date hereof.

(F)      Notwithstanding anything to the contrary in this Lease, in no event
shall the Basic Annual Rent be reduced in any way because of anything in this
Paragraph 3.

PARAGRAPH 4 SECURITY DEPOSIT: Tenant has paid or agrees to pay to Landlord such
sum(s) as are set forth in Item 9 of the Basic Lease Provisions as security for
the performance of the terms hereof by Tenant. Unless required by law, Landlord
shall not be required to keep said Security Deposit separate from its general
funds and Tenant shall not be entitled to receive interest thereon. In no
instance shall the amount of such Security Deposit be considered a measure of
liquidated damages. If Tenant defaults with respect to any provision of this
Lease, including but not limited to the provisions relating to the payment of
Rent or the surrender of the Premises in accordance with the terms hereof upon
the termination of the Lease, Landlord may, but shall not be required to use,
apply or retain all or any part of this Security Deposit for the payment of any
Rent or any other sum in default, or for the payment of any other amount which
Landlord may spend or become obligated to spend by reason of Tenant's default or
to compensate Landlord for any other loss or damage which Landlord may suffer by
reason of Tenant's default including, without limitation, costs and attorneys'
fees incurred by Landlord. If any portion of said deposit is so used or applied,
Tenant shall, upon demand therefor, deposit cash with Landlord in an amount
sufficient to restore the Security Deposit to its original amount and Tenant's
failure to do so shall constitute a default hereunder by Tenant. If Tenant shall
fully and faithfully perform every provision of this Lease to be performed by
it, the Security Deposit, or any balance thereof, shall be returned to Tenant
(or, at Landlord's option, to the permitted assignee of Tenant's interest
hereunder) within thirty (30) days following the expiration of the Lease term
and after Tenant has vacated and delivered possession of the Premises to
Landlord in accordance with the provisions of this Lease. In the event of
bankruptcy or other debtor-creditor proceeding against Tenant, such Security
Deposit shall be deemed to have been applied first to the payment of Rent and
other charges due Landlord for all periods prior to filing of such proceedings.

PARAGRAPH 5 REPAIRS: (A) Subject to subparagraph 5(B), Landlord shall cause all
necessary repairs to be made to the exterior walls, exterior doors, windows,
corridors and other common areas of the Building and the Project and Landlord
shall cause the Building and the Project to be kept in a safe, clean and neat
condition, and shall use reasonable efforts to keep all equipment used in common
with other Tenants (such as elevators, plumbing, heating, air conditioning and
similar equipment) in good condition and repair. Landlord shall also repair all
heat pumps, and shall repair or replace the heat pumps in the exterior or
peripheral areas of the Building in the Premises. Except as provided in
Paragraph 13 hereof, there shall be no abatement of Rent and no liability of
Landlord by reason of any injury to or interference with Tenant's business
arising from the making of any repairs, alterations or improvements in or to any
portion
                                      -9-

of the Building or the Project or in or to fixtures, appurtenances and equipment
therein or thereon.

(B)      Tenant agrees that all repairs to the Premises not required above to be
made by Landlord during the term of this Lease, if approved by Landlord, shall
be made by Landlord at the sole cost and expense of Tenant. Tenant will pay for
any repairs to the Premises, the Building or the Project made necessary by any
negligence or willful acts or omissions of Tenant or its assignees, subtenants,
employees or their respective agents or other persons permitted in the Building
or on the Project by Tenant, or any of them. Tenant will also maintain the
Premises, and, upon termination of this Lease, will leave the Premises in a
safe, clean, neat and sanitary condition.

PARAGRAPH 6 IMPROVEMENTS AND ALTERATIONS: (A) Landlord will provide a
construction allowance of $159,830.00 for planning, supervision and construction
of Tenant's interior Premises. Tenant shall contract separately for space
planning and preliminary design services. Landlord's sole construction
obligation under this Lease is as set forth in Landlord's Work Letter attached
hereto as Exhibit "B" and incorporated herein by this reference. Prior to the
Commencement Date, Tenant's obligations with respect to alterations and
improvements to the Premises are governed by Landlord's Work Letter. Any unused
portion of the Construction Allowance shall be applied in payment of Rent first
coming due.

(B)      Landlord shall have the right at any time to change the arrangement
and/or location of entrances or passageways, doors and doorways, and corridors,
(provided that such changes do not unreasonably interfere with Tenant's access
to the Premises) elevators, stairs, toilets, or other public parts of the
Building or Project, and, upon giving Tenant reasonable notice thereof, to
change the name, number or designation by which the Building or the Project is
commonly known.

(C)      From and after the Commencement Date, Tenant shall not make or suffer
to be made any alterations, additions or improvements (excluding decorating, and
painting) to or of the Premises or any part thereof, or attach any fixtures or
equipment thereto, without first obtaining Landlord's prior written consent,
which shall not be unreasonably withheld or delayed. Any consent by Landlord may
be subject to such reasonable conditions as Landlord may deem necessary. Any
such alterations, additions or improvements to the Premises consented to by
Landlord shall, at Landlord's option, be made by Landlord for Tenant's account
and Tenant shall pay Landlord for the cost thereof (including a reasonable
charge for Landlord's overhead) within ten (10) days after receipt of Landlord's
statement. All such alterations, additions and improvements shall (without
compensation to Tenant) immediately become Landlord's property (except easily
moveable furniture and trade fixtures) and, at the end of the term hereof, shall
remain on the Premises unless Landlord elects by notice given to Tenant at the
time of the original request for consent (which notice Landlord must give Tenant
at the time Landlord consents to the alteration, addition or improvement) to
have Tenant remove same, in which event Tenant shall promptly restore the
Premises to their condition prior to the installation of such alterations,
additions and improvements. Tenant will obtain, at Tenant's expense, all
necessary permits and certificates and Tenant shall furnish Landlord copies of
all such permits and certificates.

PARAGRAPH 7 LIENS: Tenant shall keep the Premises free from any mechanics
notices of intention, liens or encumbrances (collectively in this paragraph
hereinafter referred to as "lien" or "liens") arising out of any work performed,
materials furnished, or obligations incurred by or for Tenant. In the event that
Tenant shall not, within ten (10) days following the imposition of any such
lien, cause the same to he released of record by payment or posting of a proper
bond, Landlord shall have, in addition to all other remedies provided herein or
by law, the right, but not the obligation, to cause the same to be released by
such means as it shall deem proper, including payment of or defense against the
claim giving rise to such lien. All sums paid by Landlord and all expenses
(including, without limitation, reasonable attorneys' fees) incurred by it in
connection

                                      -10-

<PAGE>   13

therewith, shall create automatically an obligation of Tenant to pay to Landlord
an equivalent amount as Additional Rent, which Additional Rent shall be payable
by Tenant upon Landlord's demand, with interest at the maximum rate per annum
permitted by law, until paid. To the extent permitted by law, Tenant shall
require all Tenant's contractors and materialmen to waive any and all rights
they may have to file any liens.

PARAGRAPH 8 USE OF THE PREMISES: (A) Tenant shall use the Premises only as set
forth in Item 12 of the Basic Lease Provisions and shall not use or permit the
Premises to be used for any other purpose without the prior written consent of
Landlord. Tenant shall comply with all laws, and shall not use or occupy the
Premises in violation of law or of the certificate of occupancy issued for the
Building, and shall immediately discontinue any use of the Premises which is
declared by Landlord or any governmental authority having jurisdiction to be a
violation of law or of said certificate of occupancy. Tenant shall comply with
any direction of any governmental authority having jurisdiction which shall, by
reason of the nature of Tenant's use or occupancy of the Premises, impose any
duty upon Tenant or Landlord with respect to the Premises or with respect to the
use or occupancy thereof. Landlord represents that no applicable law prohibits
use of the Building for office purposes. Tenant shall not do or permit to be
done anything which will invalidate or increase the cost of any fire, extended
coverage or any other insurance policy covering the Building, the Project and/or
property located therein and shall comply with all rules, orders, regulations
and requirements of the appropriate fire rating bureau or any other organization
performing a similar function. Tenant shall upon demand reimburse Landlord for
the full amount of any additional premium charged for such policy by reason of
Tenant's failure to comply with the provisions of this paragraph. Such
reimbursement shall not be Landlord's exclusive remedy.

(B)      With respect to Tenant's use and occupancy of the Premises, Tenant
shall not store, use, or dispose of any hazardous materials, in, on, under or
about the Premises or the Project other than office supplies and cleaning
products. Tenant shall, at Tenant's own expense, comply with the Industrial Site
Recovery Act, N.J.S.A. 13:1k-6 et seq., ("ISRA") and all other applicable
federal, state, and local laws, promulgated with respect to hazardous substances
and the regulations promulgated thereunder (the "Hazardous Substances Laws").
Tenant shall, at Tenant's own expense, make all submissions to, provide all
information to, and comply with all requirements of, the New Jersey Department
of Environmental Protection or its replacement and any similar federal, state or
local department, agency, bureau or division which is charged with the
enforcement of laws regulating hazardous wastes (the "Hazardous Substances
Agencies") and promptly comply with Landlord's requirements in connection
therewith.). Should any Hazardous Substance Agency determine that a Cleanup Plan
be prepared and that a cleanup be undertaken because of any spills or discharges
of hazardous substances or wastes at the Building or land in or on which the
Premises is located which were caused by Tenant or its officers, employees,
agents, contractors or invitees, then Tenant shall, at Tenant's own expense,
prepare and execute a Cleanup Plan which shall be approved by such Hazardous
Substance Agency and complete the cleanup. If the Hazardous Substance Agency
determines that a Cleanup Plan be prepared at the Building or land for reasons
other than those stated in the preceding sentence, then Landlord at Landlord's
own expense shall prepare and execute a Cleanup Plan which shall be approved by
NJDEP and Landlord shall complete the cleanup and Tenant shall cooperate with
Landlord in every way reasonable. Tenant shall defend, indemnify and hold
harmless Landlord from and against all claims, costs, and liabilities, including
reasonable attorneys' fees, arising out of or in connection with Tenant's breach
of its obligations under this Paragraph 8. Tenant's obligations under this
paragraph 8 shall survive the expiration or earlier termination of this Lease.

PARAGRAPH 9 UTILITIES AND SERVICES: (A) Provided that Tenant is not in material
default hereunder, Landlord agrees to furnish or cause to be furnished to the
Premises the following utilities and services, subject to the conditions and
standards set forth below and
                                      -11-

                  listed in Exhibit "E" "Legal Holidays" excepted), and shall
                  have at least one elevator available for use at all other
                  times.

         (ii)     From 8:00 a.m. to 6:00 p.m., Monday through Friday (Legal
                  Holidays excepted), Landlord shall, subject to interruptions

                  furnish heat or air-conditioning subject to any governmental
                  requirements or standards relating to, among other things,
                  energy conservation. Upon reasonable, prior written request,
                  Landlord shall make available at Tenant's expense, after-hours
                  heat or air-conditioning, and Tenant shall be responsible for
                  payment of all costs associated with such after hours heat or
                  air conditioning. The charge for after-hours heat or
                  air-conditioning shall be reasonably determined by Landlord
                  and confirmed in writing to Tenant, as the same may change
                  from time to time. At the date of this Lease the charge is
                  $50.00 per hour per zone There shall be a minimum charge of
                  one hour for every partial hour of usage. Tenant shall pay the
                  after hours charges promptly and, in any event, within ten
                  (10) days after receipt of written confirmation.

         (iii)    Landlord shall furnish to the Premises, subject to
                  interruptions beyond Landlord's control and subject to

                  the building standard office lighting and receptacles. At no
                  time shall Tenant's use of electric current exceed the
                  Premises' capacity of 3.5 watts per square foot for lighting
                  and power. Landlord represents that Landlord will furnish
                  electric current of 3.5 watts per square foot for lighting and
                  power and for purposes of air supply and distribution of HVAC
                  System and that Landlord will not reduce said capacity during
                  the term hereof. To the extent Tenant design exceeds the
                  electrical current design capacity, then Tenant will pay all
                  costs of providing additional required electrical service.
                  Tenant shall pay the after hours charges promptly and, in any
                  event, within ten (10) days after receipt of written
                  confirmation.

         (iv)     Landlord shall, subject to interruptions beyond Landlord's
                  control and other provisions hereunder, furnish the building
                  with water for heating, ventilating, air conditioning,
                  drinking and lavatory purposes only.

         (v)      Landlord shall provide janitorial services to the Building and
                  Premises, in accordance with Exhibit "F" provided that the
                  Premises are kept in good order by Tenant. Tenant shall pay to
                  Landlord the cost of removal of any of Tenant's refuse and
                  rubbish to the extent that the same exceeds the refuse and
                  rubbish usually attendant upon the use of the Premises as
                  offices.

         (vi)     Landlord shall replace, as necessary, the fluorescent tubes in
                  the standard lighting fixtures installed by Landlord. Tenant
                  agrees to reimburse Landlord upon demand for the cost of such
                  fluorescent tubes and the labor and overhead for their
                  installation.

(B)      Landlord may impose a reasonable charge which Tenant hereby agrees to
pay upon demand, for any utilities and services, including without limitation,
heating, air-conditioning, electric current and water, provided by Landlord by
reason of any use of the Premises at any time other than the hours of 8:00 a.m.
to 6:00 p.m. Monday through Friday (excluding Legal Holidays), or any use beyond
that which Landlord agrees to furnish as described above, or special electrical,
cooling and ventilating needs created in certain areas by telephone equipment,
computers

                                      -12-

and other similar equipment or uses. At Landlord's option, separate meters for
such utilities and services may be installed for the Premises, and upon demand,
Tenant shall immediately pay Landlord for the installation, maintenance and/or
repair of such meters and for all charges with respect to consumption of such
utilities or services so metered or provided.

(C)      Tenant agrees to cooperate fully at all times with Landlord and to
abide by all reasonable regulations and requirements which Landlord may
prescribe for the use of the above utilities and services. Any failure to pay
any costs as described above shall constitute a breach of the obligation to pay
Rent under this Lease and shall entitle Landlord to the rights herein granted
for such breach.

(D)      Landlord shall not be liable for, and, except as otherwise provided in
subsection E below, Tenant shall not be entitled to, any abatement or reduction
of Rent by reason of Landlord's failure to furnish any of the foregoing
services, nor shall any such failure, stoppage or interruption of any such
service be construed either as an eviction of Tenant, or relieve Tenant from the
obligation to perform any covenant or agreement. However, in the event of any
failure, stoppage or interruption thereof, Landlord shall use reasonable
diligence to have service resumed promptly, and

(E)      If Landlord fails to deliver certain services as enumerated below
required under this Paragraph 9, and such failure continues for ten (10)
consecutive calendar days after Landlord's receipt of notice specifying the
exact nature of such failure and such failure is the result of Landlord's acts
or omissions and not caused by (i) Tenant or Tenant's contractors or any agent
or employee thereof, or (ii) by an event of Force Majeure as defined in
Paragraph 40 hereof, Tenant shall have the right to offset Basic Rent and
Additional Rent (except Additional Rent resulting from services requested by
Tenant) commencing on the 11th day according to the following schedule:

         Service Not Provided        Percent of Daily Basic Rent Withheld

         Elevator service                            25%

</TABLE>


(F)      Notwithstanding anything herein to the contrary, Landlord reserves the
right from time to time to make reasonable modifications to the above provisions
for utilities and services; provided, such modifications do not diminish the
level or quality of service below that level or quality which is consistent with
a first class office building.

PARAGRAPH 10 RULES AND REGULATIONS: Tenant agrees to abide by all rules and
regulations of the Building and Project ("Rules and Regulations") imposed by
Landlord as set forth in Exhibit "D" attached hereto, and as the same may be
changed from time to time upon reasonable notice to Tenant. Landlord shall not
enforce these Rules and Regulations arbitrarily among tenants. Landlord shall
not be liable for the failure of any tenant, its agents or employees to conform
to the Rules and Regulations.

PARAGRAPH 11 TAXES ON TENANT'S PROPERTY: (A) Tenant shall be liable for and
shall pay not later than ten (10) days before delinquency, all taxes, levies
and assessments levied against any personal property or trade fixtures placed by
Tenant in or about the Premises. If any such taxes, levies and assessments on
Tenant's personal property or trade fixtures are levied against Landlord or
Landlord's property or if the assessed value of the Building or the Project is
increased by the inclusion therein of a value placed upon such personal property
or trade fixtures of Tenant and if Landlord pays the taxes, levies and
assessments based upon such increased assessment,

                                      -13-

<PAGE>   16

Tenant shall, within five days after demand therefore, repay to Landlord the
taxes, levies and assessments so levied against Landlord, or the proportion of
such taxes, levies and assessments resulting from such increase in the
assessment, together with interest thereon at the default rate determined in
accordance with paragraph 36 of this Lease.

(B)      If the Tenant Improvements, whether installed and/or paid for by
Landlord or Tenant and whether or not affixed to the real property so as to
become a part thereof, are assessed for real property tax purposes at a
valuation higher than the valuation at which tenant improvements conforming to
building standard (as determined by Landlord) are assessed, then the real
property taxes and assessments levied against Landlord or the Project by reason
of such excess assessed valuation shall be deemed to be taxes levied against
personal property of Tenant and shall be governed by the provisions of
subparagraph ll(A). If the records of the tax assessor are available and
sufficiently detailed to serve as a basis for determining whether said Tenant
Improvements are assessed at a higher valuation than building standard, such
records shall be binding on both Landlord and Tenant; otherwise, the actual cost
of construction shall be the basis for such determination.

PARAGRAPH 12 OMITTED

PARAGRAPH 13 FIRE OR CASUALTY: (A) In the event that the Project (regardless of
whether the Premises or access thereto is affected) is so damaged or destroyed
to the extent of more than one-third (1/3) of its replacement cost, or to any
substantial extent by a casualty not covered by Landlord's insurance (or, in the
event Landlord self-insures which Landlord reserves the absolute right to do, by
a casualty not ordinarily covered by all-risk insurance) or during the last two
years of this Lease, Landlord, upon giving thirty (30) days notice to Tenant,
may elect to terminate this Lease.

(B)      In the event the Premises are completely destroyed or so badly damaged
that, in Landlord's reasonable opinion, repairs to the Premises cannot be
commenced within ninety (90) days and completed within one hundred eighty (180)
days from the date of damage or destruction, Landlord will so notify Tenant, in
which event this Lease may be terminated by either Landlord or Tenant by giving
thirty (30) days advance written notice, said notice to be given within 15 days
following receipt of Landlord's notice. Also, if notice of such opinion or
notice of termination has not been given, and if repairs have not been commenced
by Landlord within ninety (90) days from the date of damage or destruction, this
Lease may be terminated immediately thereafter upon written notice from Tenant
given no later than one hundred twenty (120) days after the date of damage or
destruction. In the event Tenant shall fail to terminate this Lease as provided
in this subparagraph (B) then, Tenant shall thereafter have no further right to
so terminate based upon the provisions of this subparagraph (B).

(C)      If this Lease is not terminated as provided in Subsection 13(A) and ]
13(B), or if the damage or destruction is other than as provided in Subsection
13(A) and 13(B), then Landlord shall commence within ninety (90) days after such
damage or destruction to rebuild, repair or restore the Premises and access
thereto to substantially the same condition as when the same were delivered to
Tenant, excluding any improvements owned by Tenant, and the Lease shall continue
in full force and effect.

(D)      If this Lease is terminated as provided above, Tenant's obligation to
pay Rent hereunder shall cease as of the date (i) of damage or destruction if
Premises are rendered untenantable or (ii) Tenant vacates the Premises if
Premises are not rendered untenantable.

(E)      Landlord shall in no event: be obligated to make any repairs or
replacement of any fixtures furniture, equipment or other property (real or
personal) owned by Tenant. If the Lease is not

                                      -14-



<PAGE>   17

terminated but the Premises are rendered untenantable. Rent shall abate during
the period of such untenantability in proportion to that part of the Premises
that is unfit for use in Tenant's business Tenant acknowledges (i) that Landlord
shall not obtain insurance of any kind on Tenant Improvements, alterations,
additions and improvements to the Premises owned by Tenant or on Tenant's
furniture, fixtures, equipment and other personal property, (ii) that it is
Tenant's obligation to obtain such insurance at Tenant's sole cost and expense,
and (iii) that Landlord shall not be obligated to repair any damage thereto or
replace the same. The provisions of this Paragraph 13 shall be considered an
express agreement governing any case of damage or destruction of the Premises by
fire or other casualty, and any law of the State of New Jersey, providing for
such a contingency in the absence of an express agreement, and any other law of
like import, now or hereafter in force, shall have no application in such case.

PARAGRAPH 14 EMINENT DOMAIN: In case the whole of the Premises, or such part as
shall substantially interfere with Tenant's use and occupancy thereof, shall be
taken by any lawful power or authority by exercise of the power of eminent
domain, this Lease shall terminate effective as of the date possession is
required to be surrendered to said authority. In the event of any taking (in
whole or part) of the Project whether or not the Premises or access thereto are
affected thereby which taking in Landlord's judgment will render continued
operation of the Project economically infeasible, Landlord shall have the right
to terminate this Lease. Except as provided herein, Tenant shall not, because of
any taking, assert any claim against Landlord or the taking authority for any
compensation because of such taking, and Landlord shall be entitled to receive
the entire amount of any award without deduction for any estate or interest of
Tenant. In the event the amount of property or the type of estate taken shall
not substantially interfere with Tenant's use of the Premises, and Landlord does
not terminate this Lease, Landlord shall proceed to restore the Premises (to the
extent permitted by the taking) to substantially their condition prior to such
partial taking, and a proportionate allowance shall be made to Tenant for Rent
corresponding to the time during which, and to the part of the Premises of
which, Tenant shall be so deprived on account of such taking and restoration.
Provided same shall not diminish Landlord's award in any way, nothing contained
in this Paragraph 14 shall prevent Tenant from seeking any award against the
taking authority for the taking of personal property and fixtures owned by
Tenant or for relocation expenses recoverable from the taking authority. In no
event shall Landlord be required to expend more for restoration than received
from the taking authority for such taking. For the purposes of this paragraph,
"taking" shall also include any conveyance in lieu of condemnation.

PARAGRAPH 15 ASSIGNMENT AND SUBLETTING: (A) Tenant shall not voluntarily or
involuntarily assign, sublet, mortgage or otherwise encumber all or any portion
of its interest in this Lease or in the Premises without obtaining the prior
written consent of Landlord and any such attempted assignment, subletting,
mortgage or other encumbrance without such consent shall be null and void and of
no effect.

(B)      No assignment, subletting, mortgage or other encumbrance of Tenant's
interest in this Lease shall relieve Tenant of its obligation to pay the Rent
and to perform all of the other obligations to be performed by Tenant hereunder.
The acceptance of rent by Landlord from any other person shall not be deemed to
be a waiver by Landlord of any provision of this Lease or be a consent to any
subletting, assignment, mortgage or other encumbrance. Consent to one sublease,
assignment, mortgage or other encumbrance shall not be deemed to constitute
consent to any subsequent attempted subletting, assignment, mortgage or other
encumbrance. No permitted assignment or sublease shall permit any further
assignment, subletting, mortgage or other encumbrance.

(C)      If Tenant desires at any time to assign this Lease or to sublet the
Premises or any portion thereof, Tenant shall first notify Landlord of Tenant's
desire to do so and shall submit in writing to Landlord no less than forty-five
(45) days prior to such assignment or subletting (i) the name of the proposed
subtenant or assignee; (ii) the nature of the proposed subtenant's or assignee's
business
                                      -15-


<PAGE>   18

to be carried on in the Premises; (iii) the terms and provisions of the proposed
sublease or assignment and a copy of the proposed sublease or assignment; and
(iv) such financial information as Landlord may reasonably request concerning
the proposed subtenant or assignee.

(D)      At any time within thirty (30) days after Landlord's receipt of the
information specified in subparagraph (C) above, Landlord may by written notice
to Tenant, elect (i) to take from Tenant a sublease of the Premises or the
portion thereof proposed to be subleased by Tenant, or to take an assignment of
Tenant's leasehold estate hereunder, or such part thereof as shall be specified
in said notice, upon the same terms as those offered to the proposed subtenant
or assignee, as the case may be; (ii) to give Tenant written consent to the
proposed assignment or sublease, provided that the Rent payable monthly by the
Tenant to the Landlord under the terms of this Lease shall be increased by a sum
equal to fifty (50%) percent of all rental and other considerations received by
Tenant from its subtenant or assignee in excess of the Rent payable by Tenant
under the terms of this Lease reasonable leasing commissions paid by Tenant,
free rent, payments attributable to the amortization of the cost of Tenant
improvements made to the Premises at Tenant's cost for the assignee or
sublessee, and other reasonable, out-of-pocket costs paid by Tenant, such as
attorneys' fees directly related to Tenant's obtaining an assignee or sub-
lessee; (iii) to terminate this Lease as to the portion (including all) of the
Premises proposed to be subleased or assigned with a proportionate abatement in
the Rent payable hereunder; or (iv) to deny consent, in writing, to Tenant's
proposed sublet or assignment, which shall specify the reasons for the denial.
If Landlord does not exercise any option set forth in this subparagraph (D)
within said thirty (30) days period, Landlord shall be deemed to have consented
to the proposed assignment or sublease.

(E)      Landlord shall not unreasonably exercise its rights under
subparagraph (D) (iv) above, provided all the following conditions are present:
(i) Tenant shall send notice to Landlord, in writing, including all the
information specified in subparagraph (C) above; (ii) the subtenant or assignee
is of high quality, character and financial stability consistent with the high
standards of the Building as determined by Landlord in Landlord's reasonable
business judgment; (iii) the proposed subtenant or assignee is not a party then
occupying space in the Building or party who has negotiated with Landlord for
space in the Building within the three (3) month period preceding the date of
Tenant's notice pursuant to this subparagraph (E); (iv) Tenant shall not have
publicly advertised the availability for assignment, sublease or occupancy of
all or any part of the Premises at a rental rate lower than the rate at which
Landlord is then offering to lease similar space in the Building.

(F)      Landlord, in any case which does not involve an assignment for the
benefit of creditors or an assignment growing out of, or having any connection
with, operation of law or any other of the eventualities made the subject of an
event of default in Paragraph 22 of this Lease, shall not withhold its consent
to bona-fide assignments of this Lease as a whole to "subsidiary or affiliate
corporations" as the term is hereinafter defined upon the satisfaction of the
respective conditions and upon compliance with the requirements by Tenant of all
notice provisions of this Paragraph 15. Subparagraph 15(D) shall not apply to
such an assignment. A "subsidiary or affiliate corporation" is defined for the
purposes of this Lease as a corporation or other legal entity organized and
existing or qualified or otherwise permitted to do business in the State of New
Jersey, and under common control and ownership of Tenant, or which owns and
controls Tenant or which is owned and controlled by Tenant or by any corporation
or legal entity wholly-owned and controlled directly or through other
corporations or legal entities wholly-owned and controlled by Tenant. For the
purposes of this Paragraph 15, "owned and controlled" shall, in the case of a
corporation, mean the ownership of at least fifty (50%) percent of the capital
stock entitled to vote, and shall, in the case of any other legal entity, mean
ownership of at least fifty (50%) percent of the beneficial interest therein and
at least a fifty (50%) percent voice in the management thereof:

(G)      If Tenant is a corporation, an unincorporated association or
partnership, the transfer,


                                      -16-



<PAGE>   19

assignment or hypothecation of any stock or interest in such corporation,
association or partnership, in the aggregate in excess of twenty-five (25%)
percent, shall be deemed an assignment within the meaning and provisions of this
Paragraph 15. Any initial public offering of the stock of Tenant shall not be
deemed to be an assignment and the trading of shares of stock of Tenant on any
stock exchange shall not be deemed to be an assignment.

(H)      Tenant shall not be entitled to make, nor shall Tenant make, any
claim, and Tenant hereby waives any claims, for money damages (nor shall Tenant
claim any money damages by way of setoff, counterclaim, or defense) based upon
any claim or assertion by Tenant that Landlord has unreasonably delayed its
consent or approval to a proposed assignment or subletting as provided for in
this section. Tenant's sole remedy shall be an action or proceeding to enforce
any such provision, or for specific performance, injunction, or declaratory
judgement.

PARAGRAPH 16 LANDLORD'S ACCESS TO PREMISES: Upon reasonable prior notice by
telephone, except in an emergency in which case no notice is required, Landlord
reserves and shall at any and all times have the right to enter the Premises to
inspect the same, to supply janitor service and any other service to be provided
by Landlord to Tenant hereunder, to show said Premises to prospective
purchasers, mortgagees, or tenants, to alter or repair the Premises or any
portion of the Building or Project, all without being deemed guilty of an
eviction of Tenant and without abatement of Rent, and may for that purpose erect
scaffolding and other necessary structures where reasonably required by the
character of the work to be performed, provided that the business of Tenant
shall be interfered with as little as is reasonably practicable. Tenant hereby
waives any claim for damages or any injury or inconvenience to or interference
with Tenant's business, any loss of occupancy or quiet enjoyment of the
Premises, and any other loss occasioned thereby. For each of the aforesaid
purposes, Landlord shall at all times have and retain a key with which to unlock
all of the doors in, upon and about the Premises, excluding Tenant's vaults and
safes, and Landlord shall have the right to use any and all means which Landlord
may deem proper to open said doors in an emergency in order to obtain entry to
the Premises, and any entry to the Premises obtained by Landlord by any of said
means shall not under any circumstances be construed or deemed to be a forcible
or unlawful entry into, or a detainer of the Premises, or any eviction of Tenant
from the Premises or any portion thereof. No provision of this Lease shall be
construed as obligating Landlord to perform any repairs, alterations or
decoration except as otherwise expressly agreed to be performed by Landlord.

PARAGRAPH 17 SUBORDINATION, ATTORNMENT, ESTOPPEL CERTIFICATES: (A) This Lease is
junior, subject, and subordinate to all ground leases, mortgages, deeds of
trust, and other security instruments of any kind now covering the Project or
any portion thereof. Landlord reserves the right to place liens or encumbrances
on the Project or any part thereof or interest therein superior in lien and
effect to this Lease. This Lease, at the option of Landlord, shall be subject
and subordinate to any and all such liens or encumbrances now or hereafter
imposed by Landlord without the necessity of the execution and delivery of any
further instruments on the part of Tenant to effectuate such subordination.
Notwithstanding the foregoing, Tenant covenants and agrees to execute and
deliver upon request such further instruments evidencing such subordination of
this Lease as may be requested by Landlord.

(B)      Either party ("Answering Party") shall at any time and from time to
time upon not less than ten (10) days prior notice by the other party ("Asking
Party"), execute, acknowledge and deliver to Asking Party a statement in writing
and in form and substance reasonably satisfactory to Asking Party certifying
that this Lease is unmodified and in full force and effect (or if there have
been modifications, that the same is in full force and effect as modified and
stating the modifications), and the dates to which the Basic Annual Rent,
Additional Rent and other charges have been paid in advance, if any, and stating
whether or not to the best knowledge of Tenant, Landlord is in default in the
performance of any covenant, agreement or condition contained in this Lease and,
if so specifying each such default of which Answering Party may have knowledge
and such other

                                      -17-


<PAGE>   20

matters as may be reasonably requested by Asking Party or any lender or
purchaser of the Project. Any such statement delivered pursuant to this
Paragraph 17 may be relied upon by any prospective purchaser of the fee of the
Building or the Project or any mortgagee, ground lessor or other encumbrancer
thereof or any assignee of any such person, and by any prospective assignee of
this Lease, subtenant, party acquiring Tenant or underwriter of any stock
offering by Tenant. Tenant shall also, at any time, and from time to time, upon
not less than ten (10) days prior notice by Landlord execute and deliver to
Landlord forms and documents as may be necessary for compliance with any
applicable law, statute, ordinance, rule or regulation.

(C)      Tenant agrees that in the event that any holder of any ground or
underlying lease, mortgage, deed of trust, or other encumbrance encumbering any
part of the Project succeeds to Landlord's interest in the Premises, Tenant
shall pay to such holder all rents subsequently payable under this Lease and
shall, upon request of any such person or party succeeding to Landlord's
interest, automatically become the Tenant of and attorn to such successor in
interest without change in the terms or provisions of this Lease. Such successor
in interest shall not be bound by (i) any payment of Basic Monthly Rental
Installments for more than one month in advance except prepayments in the nature
of a Security Deposit, or (ii) any amendment or modification of this Lease made
without the written consent of such successor in interest. Upon request by such
successor in interest and without cost to Landlord or such successor in
interest, Tenant shall execute, acknowledge, and deliver an instrument or
instruments confirming the attornment.

PARAGRAPH 18 SALE BY LANDLORD: In the event of a sale or conveyance by Landlord
of the Project or any part thereof, the same shall operate to release Landlord
from any and all liability under this Lease accruing after the date of such
conveyance of title. If any Security Deposit has been made by Tenant, Landlord
shall transfer such Security Deposit to the purchaser, and thereupon Landlord
shall be discharged from any further liability in reference thereto.

PARAGRAPH 19 INDEMNIFICATION AND INSURANCE: (A) Tenant shall indemnify, hold
Landlord harmless from and defend Landlord against any and all claims, loss,
costs, damage, expense or liability, including without limitation reasonable
attorneys' fees, for any injury or damages to any person or property whatsoever,
when such injury or damage has been caused in part or in whole by any default,
act, neglect, fault, or omission of Tenant, its agents, servants, employees or
invitees. This indemnity shall not require any payment by Landlord as a
condition precedent to recovery. In addition, if any person not a party to this
Lease shall institute any other type of action against Tenant in which Landlord
shall be made a party defendant, Tenant shall indemnify, hold Landlord harmless
from and defend Landlord from all liabilities and costs by reason thereof. For
the purposes of subparagraphs l9(A) and l9(B), the term "Landlord" shall also
include as indemnitees, as the case may be, Landlord's servants, employees,
officers, agents, and/or contract managers.

(B)      Landlord shall indemnify, hold Tenant harmless from and defend
Tenant against any and all claims, loss, cost, damage, expense or liability
including, without limitation, reasonable attorneys' fees for any injury or
damage to any person or property whatsoever, occurring in the Common Areas of
the Building or Project when such injury or damage has been caused in part or in
whole by any default, act, neglect, fault or omission of Landlord, its agents,
employees or invitees. This indemnity shall not require any payment by Tenant as
a condition precedent to recovery. Landlord hereby agrees to maintain in full
force and effect at all times during the term of this Lease, at Landlord's own
expense (subject to reimbursement pursuant to Paragraph 3 hereof) property
insurance on the Building and improvements (the amount of such coverages and of
all deductibles to be in Landlord's absolute and sole discretion) or to
self-insure against the losses insured against by property coverage. Landlord
shall also be entitled, at its option, to carry such other insurance, as
Landlord shall, in its sole discretion, deem appropriate and the costs of such
insurance shall be reimbursable pursuant to paragraph 3 hereof.

(D)      Tenant shall deliver to Landlord at least thirty (30) days prior to the
time such insurance is first required to be carried by Tenant, and thereafter at
least thirty (30) days prior to expiration of each such policy, certificates of
insurance evidencing the above coverage with limits not less than those
specified above. Such certificate, with the exception of Worker's Compensation,
shall expressly provide that the interest of Landlord therein shall not be
affected by any breach by Tenant of any provision of any such policy. Further,
all certificates shall expressly provide that no less than thirty (30) days
prior written notice shall be given Landlord in the event of material
alterations to or cancellation of the coverages evidenced by such certificates.

(E)      Upon demand, Tenant shall provide Landlord, at Tenant's expense,
with such increased amount of existing insurance, and such other insurance in
such limits as Landlord may reasonably require and such other hazard insurance
as the nature and condition of the Premises may require in the judgment of
Landlord, to afford Landlord adequate protection for said risks.

(F)      If on account of the failure of Tenant to comply with the
provisions of this Paragraph 19, Landlord is adjudged a co-insurer by its
insurance carrier, then any loss or damage Landlord shall sustain by reason
thereof shall be borne by Tenant and shall be immediately paid by Tenant upon
receipt of a bill therefor and evidence of such loss.

(G)      Landlord makes no representation that the limits of liability
specified to be carried by Tenant under the terms of this Lease are adequate to
protect Tenant against Tenant's undertaking under this Paragraph 19. In the
event Tenant believes that any such insurance coverage called for under this
Lease is insufficient Tenant shall provide, at its own expense, such additional
insurance as Tenant deems adequate.

PARAGRAPH 20 WAIVER OF SUBROGATION: Tenant and Landlord each agree that the
respective insurance carried by it against loss or damage by fire or other
casualty shall contain a clause whereby the insurer waives its right of
subrogation against the other party. Notwithstanding anything to the contrary in
this Lease, Landlord and Tenant hereby waive all claims for recovery from the
other party for any loss or damage to any of its property insured under valid
and collectible insurance policies to the extent of any recovery collectible
under such insurance, or which is required to be insured pursuant to paragraph
19.

PARAGRAPH 21 NO WAIVER: No failure by Landlord to insist upon the strict
performance of any covenant, agreement, term or condition of this Lease, or to
exercise any right or remedy consequent upon a breach thereof, and no acceptance
of full or partial Rent during the continuance of any such breach, shall
constitute a waiver of any such breach or of such covenant, agreement, term or
condition. Landlord's waiver, if any, shall only be as expressly stated in
writing and signed by Landlord. No consent or waiver by Landlord to or of any
breach of any covenant, condition or duty of Tenant shall be construed as a
consent or waiver to or of any other breach of the same or any other covenant,
condition or duty, unless expressly stated otherwise in writing and signed by
Landlord. No payment by Tenant or receipt by Landlord of a lesser amount than
the Rent and additional charges payable hereunder shall be deemed to be other
than a payment on account of the earliest stipulated Rent, nor shall any
endorsement or statement on any check or any letter accompanying any check or
payment for Rent be deemed an accord and satisfaction, and Landlord may accept
such check or payment without prejudice to Landlord's right to recover the
balance of such Rent or pursue any other remedy provided herein or by law.

PARAGRAPH 22 DEFAULT: (A) The occurrence of any of the following shall
constitute a material default and breach of this Lease by Tenant:

         (i)      Any failure by Tenant to pay the Rent or to make any other
                  payment required to be made by Tenant hereunder within five
                  (5) days of date due;

         (ii)     The abandonment of the Premises by Tenant which for purposes
                  of this clause means Tenant's failure to maintain the Premises
                  as required hereunder, subject to notice and right to cure as
                  provided in clause (iii) hereof;

         (iii)    Any failure by Tenant to observe and perform any of its other
                  obligations under this Lease, where such failure continues for
                  fifteen (15) days (except where a different period of time is
                  specified in this Lease) after Landlord has given Tenant
                  written notice or such other notice as may be required by law;
                  provided, however, if such obligation cannot be cured within
                  said fifteen (15) day period, such longer period (but in no
                  event more than six (6) months) as may be reasonably necessary
                  to effect such cure and upon condition that Tenant is
                  diligently and continuously proceeding to effect said cure;

         (iv)     Tenant makes, or has made, or furnishes, or has furnished, any
                  warranty, representation or statement to Landlord in
                  connection with this Lease, or any other agreement to which
                  Tenant and Landlord are parties, which is or was false or
                  misleading in any material respect when made or furnished;

         (v)      Except as permitted in this Lease, any substantial portion of
                  the assets of Tenant is transferred unless such transfer is
                  incurred in the ordinary course of Tenant's business in good
                  faith for fair equivalent consideration;

         (vi)     Tenant becomes insolvent as defined in the Federal Bankruptcy
                  Code, admits in writing its insolvency or its present or
                  prospective inability to pay its debts as they

                                      -20-

                  become due, is unable to or does not pay all or any material
                  portion in number or dollar amount) of its debts as they
                  become due, permits or suffers a judgment to exist against it
                  which affects Tenant's ability to conduct its business in the
                  ordinary course (unless enforcement thereof is stayed pending
                  appeal), makes or proposes an assignment for the benefit of
                  creditors or any class thereof for purposes of effecting a
                  moratorium upon or extension or composition of its debts,
                  proposes any such moratorium, extension or composition, or
                  commences or proposes to commence any bankruptcy,
                  reorganization or insolvency proceeding, or other proceeding
                  under any federal, state or other law for the relief of
                  debtors;

         (vii)    Tenant fails to obtain the dismissal, within ninety (90) days
                  after the commencement thereof, of any bankruptcy,
                  reorganization or insolvency proceeding, or other proceeding
                  under any law for the relief of debtors, instituted against it
                  by one or more third parties, or fails actively to oppose any
                  such proceeding, or, in any such proceeding, defaults or files
                  an answer admitting the material allegations upon which the
                  proceeding was based or alleges its willingness to have an
                  order for relief entered or its desire to seek liquidation,
                  reorganization or adjustment of any of its debts;

         (viii)   Any receiver, trustee or custodian is appointed to take
                  possession of all or any substantial portion of the assets of
                  Tenant, or any committee of Tenant's creditors, or any class
                  thereof is formed for the purpose of monitoring or
                  investigating the financial affairs of Tenant or enforcing
                  such creditors' rights.

(B)      In the event of any such default by Tenant, then in addition to any
other remedies available to Landlord at law or in equity, Landlord shall have
the option to immediately terminate this Lease and all rights of Tenant
hereunder by giving written notice of such intention to terminate. In the event
that Landlord shall elect to so terminate the Lease then Landlord may recover
from Tenant:

         (i)      any unpaid Rent which shall have accrued at the time of such
                  termination; plus

         (ii)     the amount by which the entire amount of unpaid Rent for the
                  balance of the Lease term which amount shall, at Landlord's
                  option, be immediately due and payable, is greater than the
                  fair market rental value of the Premises, but discounted at
                  the interest rate payable on United States five (5) year
                  Treasury Notes issued immediately prior to default; plus

         (iii)    any other amount necessary to compensate Landlord for
                  Landlord's loss or damage caused directly or indirectly by
                  Tenant's failure to perform its obligations under this Lease
                  including, but not limited to, reasonable attorneys' fees and
                  costs; plus

         (iv)     at Landlord's election, such other amounts in addition to, or
                  in lieu of the foregoing, as may be permitted from time to
                  time by applicable law.

(C)      In the event of any such default by Tenant, Landlord shall also
have the right, with or without terminating this Lease, to reenter and to take
possession of the Premises and to remove all persons and property from the
Premises. Landlord is hereby granted a lien, in addition to any statutory lien
or right to distrain that may exist, on all personal property of Tenant in or
upon the Premises, to assure payment of the Rent and performance of the
covenants and conditions of this Lease. Landlord shall have the right, as agent
of Tenant, to take possession of all personal property of Tenant found in or
about the Premises including without limitation furniture and fixtures of Tenant
and, to sell the same at public or private sale and to apply the proceeds
thereof to the payment of any monies due or becoming due under this Lease, or to
remove all such effects and store same in a public warehouse or elsewhere at the
cost of and for the account of Tenant, or

                                      -21-


<PAGE>   24

any other owner or occupant, Tenant hereby waiving the benefit of all laws
exempting property from execution, levy and sale on distress or judgment.

(D)      In the event of abandonment of the Premises by Tenant or in the
event that Landlord shall elect to reenter as provided above or shall take
possession of the Premises pursuant to legal proceeding or pursuant to any
notice provided by law, then if Landlord does not elect to terminate this Lease
as provided in this Paragraph 22, Landlord may from time to time, without
terminating this Lease, either recover all Rent as it becomes due or relet the
Premises or any part thereof for such term or terms and at such commercially
reasonable rental or rentals and upon such other commercially reasonable terms
and conditions as Landlord in its sole discretion may deem advisable with the
right to make alterations and repairs to the Premises. Tenant hereby waives all
Tenant's rights under N.J.S.A. 2A: 18-60.

(E)      In the event that Landlord shall elect to so relet, then rentals
received by Landlord from such reletting shall be applied: first, to the payment
of any indebtedness other than Rent due hereunder from Tenant to Landlord;
second, to the payment of any cost of such reletting including, but not limited
to, broker's commissions and reasonable attorneys' fees; third, to the payment
of the cost of any alterations and repairs to the Premises; fourth, to the
payment of Rent due and unpaid hereunder; and the residue, if any, shall be held
by Landlord and applied in payment of future Rent as the same may become due and
payable hereunder. Should any such reletting result in the payment of rentals
less than the Rent payable by Tenant hereunder, then Tenant shall pay such
deficiency to Landlord immediately upon demand therefor by Landlord. Tenant
shall also pay Landlord as soon as ascertained, any costs and expenses incurred
by Landlord in such reletting or in making such alterations and repairs not
covered by the rentals received from such reletting.

(F)      No reentry or taking possession of the Premises by Landlord
pursuant to this Paragraph 22 shall be construed as an election to terminate
this Lease unless a written notice of such intention be given to Tenant.
Notwithstanding any reletting without termination by Landlord because of any
default by Tenant, Landlord may at any time after such reletting, elect to
terminate this Lease for any such default.

PARAGRAPH 23 RIGHT OF LANDLORD TO CURE TENANT'S DEFAULT: If Tenant defaults in
the making of any payment or in the doing of any act herein required to be made
or done by Tenant, then Landlord may, but shall not be required to, make such
payment or do such act and charge to Tenant the amount of all costs in
connection therewith including, but not limited to, reasonable legal fees and
expenses incurred by Landlord, with interest thereon as provided in Paragraph 36
from the date paid by Landlord to the date of payment thereof by Tenant. Such
payment and interest shall constitute Additional Rent hereunder due and payable
upon demand but the making of such payment or the taking of such action by
Landlord shall not operate to cure such default or to stop Landlord from the
pursuit of any other remedy to which Landlord would otherwise be entitled.

PARAGRAPH 24 NOTICES: All notices which Landlord or Tenant may be required or
may desire to serve on the other may be delivered either personally, by courier,
or by mailing the same by registered or certified mail, return receipt
requested, postage prepaid, addressed as set forth in Item 13 of the Basic Lease
Provisions, or addressed to such other address or addresses as either Landlord
or Tenant may from time to time designate to the other by written notice.

or assignable by operation of law and in no event shall this Lease be an asset
of Tenant in any receivership, bankruptcy, insolvency, or reorganization
proceeding.

                                      -22-


<PAGE>   25

termination hereof, Tenant shall peaceably surrender the Premises broom clean,
in the same, condition that the Premises were in on the Commencement Date,
except for ordinary wear and tear, damage by fire or other casualty that Tenant
is not required to repair, repairs required to be completed by Landlord. On or
before the last day of the Lease term or the sooner termination hereof, Tenant
shall at its expense remove its trade fixtures, signs and other personal
property from the Premises. Any property not removed shall be deemed abandoned
and may either be retained by Landlord as its property, or disposed of, without
accountability and at Tenant's expense, in such manner as Landlord may
determine. If the Premises are not surrendered at the end of the Lease term or
the sooner termination Tenant shall indemnify Landlord against loss or liability
resulting from delay by Tenant in so surrendering the Premises, including,
without limitation, claims made by any succeeding tenants founded on such delay.
Tenant shall promptly surrender all keys for the Premises and Building restrooms
to Landlord at the place then fixed for payments of Rent. Tenant's covenants
hereunder shall survive the expiration or termination of this Lease.

(B)      If Tenant holds over after the expiration or sooner termination
hereof without the express written consent of Landlord, Tenant shall become a
Tenant at sufferance only at two times the greater of (i) the Rent due hereunder
or (ii) the then prevailing market rate rent, as determined by Landlord in its
sole and absolute discretion, plus all items of Additional Rent provided herein,
and either (i) or (ii) shall be prorated on a daily basis according to the
number of days contained in the month that such expiration or earlier
termination takes place, and otherwise upon the terms, covenants and conditions
herein specified, so far as applicable. Acceptance by Landlord of Rent after
such expiration or earlier termination shall not constitute a consent to a
holdover hereunder or result in a renewal. The foregoing provisions of this
paragraph are in addition to and do not affect Landlord's rights of reentry or
any other rights of Landlord hereunder or as otherwise provided by law.

PARAGRAPH 27 CONDITION OF PREMISES: Landlord's responsibility with respect to
the condition of the Premises is set forth in Exhibit "B-1" Landlord's Work
Letter. Tenant acknowledges that except as expressly set forth herein neither
Landlord nor any agent of Landlord has made any representation or warranty with
respect to the Premises, the Building or the Project or with respect to the
suitability of any part of the Project for the conduct of Tenant's business. The
taking of possession of the Premises by Tenant shall conclusively establish that
the Building and the Premises were at such time in good order and repair.

PARAGRAPH 28 QUIET POSSESSION: Upon Tenant's paying the rent reserved hereunder
and observing and performing all of the covenants, conditions and provisions on
Tenant's part to be observed and performed hereunder, Tenant shall have quiet
possession of the Premises for the entire term hereof, subject to all of the
provisions of this Lease. This covenant shall be binding upon any landlord
hereunder only during its respective ownership of the Premises.

PARAGRAPH 29 LIMITATION OF LANDLORD'S LIABILITY: (A) Landlord and its employees
and agents shall not be liable for any damage to Tenant's property entrusted to
employees of Landlord or its agents, nor for any loss or interruption of
Tenant's possession, nor for loss of or damage to any property by theft or
otherwise, nor for any injury or damage to property resulting from fire,
explosion, falling plaster, steam, gas, electricity, water or rain which may
leak from any part of the Building or from the pipes, appliances or plumbing
works therein or from the roof, street or sub-surface or from any other place or
resulting from dampness or any other cause whatsoever in the Building or the
Project. Landlord and its employees and agents shall not be liable for any
property loss resulting from any latent defect in the Premises or in the
Building. Tenant shall give prompt notice to Landlord in case of fire, accidents
or defects in the Premises or in the Building.

(B)      Tenant shall look solely to Landlord's estate and property in the
Project (or the proceeds thereof) for the satisfaction of Tenant's remedies for
the collection of a judgment (or other judicial

                                      -23-

<PAGE>   26

process) requiring the payment of money by Landlord in the event of any default
by Landlord hereunder, and no other property or assets of Landlord or Landlord's
partners or members shall be subject to levy, execution or other enforcement

either this Lease, the relationship of Landlord and Tenant hereunder, or
Tenant's use and occupancy of the Premises.

PARAGRAPH 30 GOVERNING LAW: This Lease shall be governed by and construed

from time to time for general use, subject to such rules and regulations as
maybe adopted by the Landlord including, but not limited to, the right to close
from time to time all or any portion of said common facilities to such extent as
may be legally sufficient, in Landlord's sole opinion, to prevent a dedication
thereof or the accrual of rights to any person or to the public therein.

PARAGRAPH 32 SUCCESSORS AND ASSIGNS: Except as otherwise provided in this Lease,
all of the covenants, conditions and provisions of this Lease shall be binding
upon and shall inure to the benefit of the parties hereto and their respective
heirs, personal representatives, successors and assigns. However, the
obligations of Landlord under this Lease shall not be binding upon Landlord
herein named with respect to any period subsequent to the transfer of its
interest in the Project as owner or lessee thereof, and in the event of such
transfer said obligations shall thereafter be binding upon each transferee of
the interest of Landlord herein named as such owner or lessee of the Project,
but only with respect to the period commencing with its respective transfer in
and ending with a subsequent transfer out, and such transferee, by accepting
such interest, shall be deemed to have assumed such obligations except only as
may be expressly otherwise provided in this Lease. Any lease of all or
substantially all of Landlord's interest in the Project as owner or lessee
thereof shall be deemed a transfer, to the tenant under such lease, within the
meaning of Paragraph 32.

or indirectly dealt with any real estate broker(s) other than the firm(s)

retain or consult with any real estate broker or brokers other than the firms

matters pertaining to this Lease, the Premises or the Project, the employing
party hereby agrees to pay the broker or brokers and the employing party hereby

PARAGRAPH 34 NAME: LANDLORD'S RIGHTS: (A) Tenant shall not, without the written
consent of Landlord, use the name of the Building or the Project for any purpose
other than as the address of the business to be conducted by Tenant in the
Premises, and in no event shall Tenant acquire any rights in or to such names.
Landlord reserves the right to change the name and/or address of the Building or
Project at any time and from time to time, and agrees to give reasonable notice
of same to Tenant.

(B)      It is understood and agreed that the architectural design,
aesthetic appeal and use of the Building and the Project are and shall remain
always in the sole control of Landlord. Therefore, notwithstanding anything to
the contrary contained herein, Landlord does hereby reserve the right from time
to time and at any time to make changes and additions, without restriction, to
the Building and the Project, improvements or other areas, including without
limitation, eliminating land, adding other lands, decreasing or changing the
Building and the Project, which are deemed desirable by Landlord, and the making
of such changes or additions shall not invalidate or affect this Lease or any
rights hereunder nor constitute an eviction of Tenant or a breach of this Lease,
nor give rise to any claim for damages. Notwithstanding the foregoing
provisions, Landlord represents and confirms that no such changes will
unreasonably and substantially interfere with Tenant's use and occupancy of the
Premises or Tenant's access to the Building.

PARAGRAPH 35 EXAMINATION OF LEASE: Submission of this instrument for examination
or signature by Tenant does not constitute a reservation of or option for lease,
and it is not effective as a lease or otherwise until execution by and delivery
to both Landlord and Tenant.

PARAGRAPH 36 ADDITIONAL CHARGES: Any amount due from Tenant to Landlord which is
not paid when due, in addition to other remedies available to Landlord shall, at
Landlord's option, bear interest which shall be at the lesser of (i) eighteen
(18%) percent per annum or (ii) the maximum lawful rate per annum, from the date
such payment is due until the date actually paid, but the payment of such
interest shall not excuse or cure the default. In addition to the foregoing,
unless prohibited by law, Landlord may also impose a late charge of four (4%)
percent of the amount past due, and a charge for reasonable legal fees and
costs.

PARAGRAPH 37 DEFINED TERMS AND ADDITIONAL HEADINGS: The words "Landlord" and
"Tenant" as used herein shall, as the case may be, include the plural as well as
the singular. If more than one person or entity is named as Tenant the
obligations of such persons or entities are joint and several. The marginal
headings and titles to the Paragraphs of this Lease are not a part of this Lease
and shall have no effect upon the construction or interpretation of any part
hereof. This Lease shall be construed without regard to any presumption or other
rule requiring construction against the party causing this Lease to be drafted.

PARAGRAPH 38 PRIOR AGREEMENTS; SEVERABILITY: This Lease contains all of the
agreements of the parties hereto with respect to any matter covered or mentioned

pertaining to any such matter shall be effective for any purpose. No provision
of this Lease may be amended or added to except by an agreement in writing
signed by the parties hereto or their respective successors in interest. If any
term or provision of this Lease, the deletion of which would not adversely
affect the receipt of any material benefit by either party hereunder, shall be
held invalid or unenforceable to any extent, the remainder of this Lease shall
not he affected thereby and each term and provision of this Lease shall be valid
and enforceable to the fullest extent permitted by law.

PARAGRAPH 39 PARKING: Tenant shall have the right to the use of the number of
parking spaces (the "Parking Spaces") shown in Item 10 of Basic Lease

and regulations which Landlord may from time to time make to assure proper use
of parking spaces by permitted users, including but not limited to the
prohibition

                                      -25-

tenant of said rules and regulations.

PARAGRAPH 40 FORCE MAJEURE: Except as otherwise expressly provided herein, this
Lease and the obligations of Tenant to pay Rent hereunder and perform all of the
other covenants, agreements, terms, provisions and conditions hereunder on the
part of Tenant to be performed shall in no way be affected, impaired or excused
because Landlord is unable to fulfill any of its obligations under this Lease,
if Landlord is prevented or delayed from so doing by reason of any cause beyond
Landlord's reasonable control including, but not limited to, Acts of God,
strikes, labor troubles, shortage of materials, governmental preemption in
connection with a national emergency or by reason of any rule, order or
regulations of any governmental agency or by reason of war, hostilities or
similar emergency; provided that Landlord shall in each instance exercise
reasonable diligence to effect performance as soon as possible. It is agreed
that Landlord shall not be required to incur any overtime or additional expenses
in Landlord's reasonable diligence to effect the performance of any of
Landlord's obligations hereunder.

PARAGRAPH 41 NO LIGHT, AIR OR VIEW EASEMENT: Any diminution or shutting off of
light, air or view by any structure which may be erected on lands adjacent to

Tenant does hereby personally covenant and warrant that Tenant is a duly
authorized and existing entity as herein represented, that Tenant was and is
qualified to do business in the State of New Jersey, that the Tenant has full
right and authority to enter into this Lease, and that each person signing on
behalf of the Tenant is authorized to do so. Upon Landlord's request, the

PARAGRAPH 44 TENANT'S OPTION TO RENEW: Upon condition that Tenant is not in
default in the payment of any Basic Annual Rent, Additional Rent or other charge
payable by Tenant under this lease and is not in default in the performance of
any covenant or obligation to be performed by Tenant under this lease; and upon

<PAGE>   29

Lease, for one further term of five (5) years, pursuant and subject to all the
terms, covenants, provisions and conditions of this lease, including, without
limitation, the payment of all items of Additional Rent as provided for
hereunder, except that Basic Annual Rent shall be adjusted to the then fair
market rent.

PARAGRAPH 45 FAIR MARKET RENTAL VALUE - APPRAISAL: (A) For purposes of Paragraph
44, "fair market rental value:" shall mean that rental value for the Premises
under the existing zoning on an "as is" basis which a landlord and tenant would
agree to in an arms-length transaction. If Tenant disagrees with the fair market
rental value determined by Landlord, then Tenant shall within thirty (30) days
of Landlord's notice so advise Landlord in writing, and thereafter, Landlord and
Tenant shall use their best efforts to reach agreement on the fair market rental
value during the thirty (30) days following Tenant's giving Landlord notice to
renew and extend this Lease.

(B)      If Landlord and Tenant cannot reach agreement, the fair market
rental value of the Premises shall be determined by an appraisal made by three
reputable New Jersey real estate appraisers who shall be appointed in the manner
hereinafter provided and each of whom shall be a member of the American
Institute of Real Estate Appraisers or a successor body hereinafter constituted
exercising a similar function, shall have experience in appraising property
similar to the Premises, and shall have no substantial direct or indirect
financial or other business interests in Landlord, or its affiliates, or Tenant
or its affiliates. The appraisal of the Premises will be conducted by three
reputable real estate appraisers, one appointed by Landlord, one appointed by
Tenant and the third appointed by the first two appraisers. The costs and
expenses of each appraiser appointed separately by Tenant and Landlord will be
borne by the party who appointed the appraiser. The costs and expenses of the
third appraiser will be shared equally by Landlord and Tenant. Any appraisal
process required pursuant to this lease may be commenced by Landlord or Tenant
(the "Initiating Party") by notice to the other (the "Other Party") in which the
Initiating Party appoints its appraiser. Said notice shall be given no earlier
than thirty (30) days after Tenant sends Landlord notice of exercise of the
renewal option. The Other Party shall appoint its appraiser by notice given to
the Initiating Party within twenty (20) days after the Initiating Party's
Notice. The appraisers appointed by the Initiating Party and the Other Party
shall select a third appraiser within twenty (20) days of the appointment of the
appraiser appointed by the Other Party. If the first two appraisers are unable
to agree on a third appraiser, such third appraiser shall be appointed by the
President of the Society of Real Estate Appraisers, North Jersey Chapter,
Chatham, New Jersey. If such individual refuses to act, such third appraiser
shall be appointed pursuant to the rules of the American Arbitration
Association, as the same are applicable in the State of New Jersey.

(C)      The appraisers shall appraise the Premises, and notify Tenant and
Landlord by written notice of the fair market rental value which notices shall
be accompanied by copies of their appraisal reports. If the determinations of
the fair market rental value of any two or all three of the appraisers shall be
identical in amount, said amount shall be deemed to be the fair market rental
value, but if such determinations of all three appraisers shall be different in
amount, the appraised value which is the closest in amount to the middle
appraised value, whether it be the highest or the lowest appraised value, shall
be averaged with the middle appraised value and the resulting averaged appraised
value shall be the fair market value of the Premises. The appraised value which
is the furthest from the middle appraised value will not be utilized or
considered.

(D)      The fair market rental value, determined in accordance with the
provisions of this Paragraph, shall be binding and conclusive on Tenant and
Landlord. Notwithstanding the foregoing, if the Other Party shall fail to
appoint the appraiser to be appointed by such Other Party within twenty (20)
days after the Initiating Party's notice requiring the Other Party to do so, the
appraisal shall be conducted only by the appraiser appointed by the Initiating
Party, and the fair market rental value as determined by the appraiser appointed
by the Initiating Party shall be binding and conclusive upon Landlord and
Tenant. Anything herein to the contrary notwithstanding,

                                      -27-

<PAGE>   30

Landlord and Tenant shall have similar rights to appeal said determination which
may then exist under New Jersey Law with respect to binding arbitration.

Premises during construction and at completion. If, during any inspection of the

any objections to the work, Landlord shall advise Tenant of any such problems or
objections within a reasonable period of time after such inspection. After
Landlord's inspection and upon completion of all Tenant's Work and issuance of a
permanent Certificate of Occupancy and upon Tenant's presenting satisfactory
evidence to Landlord of actual payments of cost of Tenant's work, Landlord will
pay the second (and final) installment of the Work Allowance.

D.       DELAYS

         If Tenant shall cause any delay in the construction of the Premises,
whether by reason of any failure by Tenant to comply with the applicable time
schedule or by Tenant's requirement of specific materials or installations, or
by delays in performance of completion by a party employed by Tenant, or by
reason of building code problems arising from Tenant's design,


                                      -33-
<PAGE>   36

or by reason of changes in the work ordered by Tenant, then notwithstanding the
provisions of the Lease or any other provision of this Exhibit, any such delay
in completing the Premises shall not in any manner affect the Commencement Date
or Tenant's liability for the payment of Rent as set forth in the Lease.

         E.       INCORPORATION IN LEASE

         This Work Letter is, and shall be incorporated by reference in the
Lease and all of the terms and provisions of said Lease are and shall be
incorporated herein by this reference.

cost of all electricity consumed by Tenant in the Premises. Said cost shall be

terms and conditions of the Lease, such obligation shall be deemed to mean that
Tenant shall comply with the terms and conditions of the Lease to the extent not
inconsistent with Tenant's performance of the work.

Parking Areas is limited or prohibited by any governmental authority, or the use
or operation of the Parking Areas is limited or prevented by strikes or other
labor difficulties or other causes beyond Landlord's control, Tenant's inability
to use the Parking Spaces will not subject Landlord or any operator of the
Parking Areas to any liability to Tenant and will not relieve Tenant of any of
its obligations under the Lease and the Lease will remain in full force and
effect. Tenant will pay to Landlord upon demand, and Tenant indemnifies Landlord
against, any and all loss or damage to the Parking Areas, or any equipment,
fixtures, or signs used in connection with the Parking Areas and any adjoining

or obligations of Tenant pursuant to the provisions of the Paragraphs of the
Lease, the provisions of the Paragraphs shall govern.
