further covenants and agrees that it shall add Landlord as an additional

          C. Tenant shall not do nor permit anything in the Demised Premises or
bring or keep anything therein that shall, in any way, increase the rate of fire
insurance in the building in which the Demised Premises is located, or on the

tenants, or in any way injure or annoy them or those having business with them,
or conflict with the regulations of the fire department or the fire laws or with
any insurance policies upon the building in which the Demised Premises is
located, or any part thereof. Tenant shall comply with any and all laws, rules
and ordinances established by the Board of Health or other governmental agencies
or authorities. In the event there is any increase in the fire insurance
premiums as the result of the acts or omissions of the Tenant, its agents,
servants, or employees, Tenant hereby covenants to pay on demand, as Additional
Rental an amount equal to the aforesaid increase in insurance premiums.

          D. All policies of liability insurance to be provided by Tenant or
Landlord pursuant to this Paragraph covering and insuring the Demised Premises,
shall expressly waive any right of subrogation on the part of the insuror
against Landlord or Tenant, as applicable, which right, to the extent not
prohibited or violative of any such policy, is hereby expressly waived by Tenant
against Landlord and waived by Landlord against Tenant. This paragraph and the
waiver of claims/subrogation has priority over any other clause of the Lease
which may be in conflict.

     11. Tenant shall have the right to erect a sign on exterior of the Building
subject to Landlord's consent, and approval of Hopewell Township zoning or
ordinances; and such sign


                                      -12-

<PAGE>

shall be removed at the end of Tenant's leasehold with any damaged repaired by
Tenant. Landlord shall have Tenant's corporate name printed on existing sign on
the Demised Premises.

     12. If, during the Term of this Lease, the building of which the Demised
Premises is a part shall be damaged by fire or other casualty and if such damage
cannot be repaired with one hundred twenty (120) working days of the usual
working hours, the Landlord shall have the right to cancel and terminate this
Lease as of the date of the damage by giving the Tenant written notice thereof
within thirty (30) days after the date of such damage. If such notice is not
given or if the damage can be repaired within one hundred twenty (120) days,
Landlord shall restore such building with reasonable diligence, and if the
Demised Premises is rendered untenantable by such damage, the Rental shall be
proportionately abated until it is restored. In the event Landlord determines
that the damage cannot be repaired within the one hundred twenty (120) working
days set forth above, Landlord shall provide Tenant with written notice thereof.
Within thirty (30) days after Tenant's receipt of said notice from Landlord,
Tenant shall have the right to terminate the within Lease by providing written
notice to Landlord. Furthermore, in the event the damage is not substantially

permitted to provide Landlord with thirty (30) days notice of Tenant's intention
to terminate the Lease. The Lease shall terminate and Tenant shall vacate the
Demised Premises at the expiration of the thirty (30) day notice period unless
prior to such date Landlord has substantially repaired any and all damage.

     13. In the event that the Tenant shall remain in the Demised Premises after
the expiration of the Term of this Lease without having executed a new written
lease with the Landlord, such holding over shall not constitute a renewal or
extension of the Lease. The Landlord may, at its option, elect to treat the
Tenant as one who has not removed at the end of its Term and thereupon be
entitled to all remedies against the Tenant provided by law in that situation,
or the Landlord may elect, at its option, to construe such holding over as a
tenancy from month-to-month and subject to all the terms and conditions of this
Lease, except as to duration thereof. In the event Tenant remains in the Demised
Premises with Landlord's consent, during the first three (3) months of said
holdover period, Tenant shall pay monthly Rental, in advance, at the rate of
125% of the then existing monthly Rental effective during the last month of the
Term. In the event Tenant remains in the Demised Premises without Landlord's
consent, or if Tenant remains beyond the three (3) month period set forth above
with Landlord's consent,


                                      -13-

<PAGE>

then Tenant shall pay monthly Rental in advance at the rate of 150% the then
existing monthly Rental effective during the last month of the Term. Additional
Rental shall continue to be paid as required in this Lease.

     14. It is further agreed that if any installment of Rental or Additional
Rental is not paid within ten (10) days following notice by Landlord to Tenant
after such payment is due, or if Tenant shall breach any of the other terms,
covenants, provisions and conditions of this Lease, or the rules and regulations
hereinafter mentioned, the Tenant shall be in default hereof and Landlord shall
have available all remedies provided by law. Tenant hereby waives any
requirement as to notice hereunder and further waives any and all rights or
claims for redemption of any Rentals or payments or for repossession of the
Demised Premises or any portion thereof. Notwithstanding the foregoing, Landlord
shall provide Tenant with written notice of any non-monetary default and Tenant
shall have thirty (30) days within which to cure said default and such
additional time as may be reasonably necessary providing Tenant is promptly,
continuously and diligently pursuing a cure.

     15. Landlord, its agents or employees, may enter to clean, examine and
exhibit the Demised Premises and may make repairs and improvements therein and
in and to any portion of the building in which the Demised Premises is located,
and for such purpose shall have the right to install pipes and wires and
otherwise utilize the Demised Premises, including the right to break floors,
walls and ceilings, and to move cases, fixtures and floor coverings when
desirable for such purposes, but same is to be done so as to inconvenience not
more than is reasonably necessary.

     30. This Lease and obligation of Tenant to pay rent hereunder and perform
all of the other covenants and agreements hereunder on part of Tenant to be

  ($5,549.15 PER MONTH) (THIS AMOUNT IS SUBJECT TO ANNUAL INCREASES BASED UPON
          ACTUAL TRIPLE NET COSTS, DEFINED HEREIN AS ADDITIONAL RENTAL)

Tenant's proportionate share of Additional Rental is defined as that fraction,

Fourth Lease Year ($176,859.50) plus the percentage of increase, if any, in the
Consumer Price Index, computed as follows:


                                       -5-

<PAGE>

     A.   There shall be compared the Consumer Price Index for All Urban
          Consumers, New York, N.Y. - Northeastern New Jersey Local Area, All
          Items, published by the Bureau of Labor Statistics, Revised Consumer
          Price Index, effective January, 1987 (1982-84 = 100) (the Index) for
          the first month of the Fifth Lease Year with the first month of the
          First Lease Year. The percentage of increase in such Index for the
          first month of the Fifth Lease Year over the first month of the First
          Lease Year shall be the percentage of increase in the Index for the
          purpose of determining the increase in the Annual Rental payable
          during the Fifth Lease Year of this Lease.

     B.   It is understood and agreed that in the event the Index figure
          required to make the foregoing comparison shall not be published for
          the particular month when the same shall be applicable, then the like
          Index figure published in any preceding month shall be used provided
          such figure is published within three (3) months of the month required
          in accordance with the foregoing. In the event that the applicable
          Index figure is not published within three (3) months of the required
          month or if such figure or the entire Index shall become unavailable
          by reason of discontinuance of publication or any other reason, then
          in any such event, the parties shall agree on an equivalent and
          substituted Consumer Price Index to be applied in the same manner as
          herein provided.

     C.   The parties covenant and agree that as soon as the Index figure for
          the first month of the Fifth Lease Year of this Lease is published
          they will set forth such figure in writing signed by both parties; and
          thereafter, when the figure is published for any succeeding month to
          be used for comparison as hereinabove provided, they will likewise set
          forth such figure in writing signed by both parties. The failure to
          set forth such figures in writing shall not diminish Tenant's
          obligations hereunder.

     D.   The Annual Rental for the Sixth, Seventh and Eighth Lease Years shall
          be the Annual Rental in effect at the expiration of the prior Lease
          Year plus the percentage of increase, if any, in the Consumer Price
          Index, computed as set forth above using the applicable Lease Years.
          In no event shall the Annual Rental be less than that in effect for
          the prior Lease Year.
