            3. First Floor Space. (a) Landlord hereby leases to Tenant and
Tenant hereby hires from Landlord the First Floor Space for a term (the

Commencement Date, and except as set forth herein, all references in the Lease
to the "demised premises" shall be deemed to include the First Floor Space and
the provisions and conditions of the Lease shall apply to the First Floor Space
with the same force and effect as if such space were leased to Tenant together

date immediately preceding the First Floor Space Commencement Date (the
"Preparation Period") Tenant shall be entitled to occupy the First Floor Space
for the purpose of performing Tenant's initial work therein and, upon completion
of such work, for the purposes expressly permitted pursuant to Article 5 of the
Lease. Tenant's occupancy of the First Floor Space during the Preparation Period
shall be subject to all of the terms and conditions of the Lease (including,

      Tax Share shall be increased by 1.05% and Tenant's Expense Share shall be
      increased by 1.10%.

            (d) The parties acknowledge that for all purposes of the Lease, as
amended hereby, the First Floor Space shall be deemed to contain 15,776 rentable
square feet.

            (e) Except as provided in paragraph 3 above with respect to the
payment of basic annual rent and Taxes and Operating Expenses from the First
Floor Space Possession Date through and including the day immediately preceding
the First Floor Space Commencement Date, Tenant shall pay additional rent and
any and all other amounts payable with respect to the First Floor Space from and
after the First Floor Space Possession Date at the times and in the manner set
forth in the Lease (as amended hereby). Tenant shall pay basic annual rent and
Taxes and Operating Expenses with respect to the First Floor Space from and
after the First Floor Space Commencement Date at the times and in the manner set
forth in the Lease (as amended hereby). If the First Floor Space Commencement
Date falls on any day other than the first day of a month, then the basic annual
rent for the First Floor Space for such month shall be prorated on a per diem
basis, and Tenant agrees to pay the amount thereof for such partial month on the
First Floor Space Commencement Date. If the first day of the Second Rent Period
falls on any day other than the first day of a month, then the basic annual rent
for the First Floor Space for the month in which the Second Rent Period
commences shall be prorated on a per diem basis to reflect the number of days of
such Second Rent Period and of the First Rent Period which occur during such
month.

            (f) Tenant shall be entitled to reimbursement of up to an amount
equal to $236,640.00 (the "First Floor Space Allowance") for Hard Costs and Soft
Costs paid by Tenant in connection with the preparation of the First Floor Space
for Tenant's occupancy; provided, that Tenant shall not be entitled to
reimbursement from the First Floor Space Allowance for Soft Costs to the extent
such Soft Costs exceed an amount (the" First Floor Space Soft Costs Maximum")
equal to $59,160.00. Tenant shall have the right to submit to Landlord, from
time to time, but not more frequently than once per month, a notice setting
forth the dollar amount requested, which notice shall be accompanied by (i) paid
invoices or other evidence reasonably satisfactory to Landlord of the amounts
paid by Tenant for such Hard Costs and/or Soft Costs, (ii) a certificate from a
financial officer of Tenant that Tenant has not been reimbursed previously for
such Hard Costs and/or Soft Costs, (iii) a certificate from Tenant's architect
which certifies that the work for which Tenant is seeking reimbursement has been
completed substantially in accordance with the plans and specifications
previously approved or deemed approved by Landlord and in compliance with all
applicable Legal Requirements and (iv) evidence reasonably satisfactory to
Landlord (including, without limitation, lien waivers) that all sums properly
due and owing to contractors, subcontractors and materialmen in connection with
the work for which


                                     - 3 -

receipt of such notice and other information and provided the certificates and
other deliveries made therewith are correct, Landlord shall reimburse Tenant for
the amount thereof until the total of all such reimbursements is equal to the
First Floor Space Allowance (it being understood that in no event shall Landlord
be obligated to expend in excess of the First Floor Space Allowance or reimburse
Tenant for Soft Costs in excess of the First Floor Space Soft Costs Maximum).
Anything to the contrary contained herein notwithstanding anything, Landlord
shall have the right to withhold $25,000 from the First Floor Space Allowance,
which amount shall not be released to Tenant unless and until Tenant delivers to
Landlord final working drawings, with amendments, or the mylar set of "as built"
plans, drawings and specifications for the work performed in the First Floor
Space and the disk carrying the same in accordance with Section 6.01(11) of the
Lease.

undertaken by Tenant to prepare, equip, decorate and furnish the First Floor
Space for Tenant's occupancy shall be performed by Tenant at Tenant's expense in
accordance with all of the terms, conditions and provisions of the Lease. In
addition, Tenant shall be responsible for bringing electric service to the First
Floor Space from either the Demised Premises or the switchgear room located on
the sixth floor of the Building.

            5. Right of First Offer. Landlord and Tenant acknowledge and agree
that Article 49 of the Lease (Right of First Offer) is null and void and of no
further force and effect.

            6. Sixth Floor Space. (a) Landlord hereby leases to Tenant and
Tenant hereby hires from Landlord the Sixth Floor Space for a term (the "Sixth
Floor Space Term") to commence on the Sixth Floor Space Commencement Date and
ending on the Expiration Date, unless the Term shall sooner cease and terminate
as provided in the Lease. Effective as of the Sixth Floor Space Commencement
Date, and except as set forth herein, all references in the Lease to the
"demised premises" shall be deemed to include the Sixth Floor Space and the
provisions and conditions of the Lease shall apply to the Sixth Floor Space with
the same force and effect as if such space were leased to Tenant together with
the "demised premises" originally leased to Tenant under the Lease. For the
period commencing on the Sixth Floor Space Possession Date and ending on the
date immediately preceding the Sixth Floor Space Commencement Date (the

            (e) Tenant shall be entitled to reimbursement of up to an amount
equal to $1,185,222.50 (the "Sixth Floor Space Allowance") for Hard Costs and

sums properly due and owing to contractors, subcontractors and materialmen in
connection with the work for which Tenant is seeking reimbursement have been
paid. Within thirty (30) days after receipt of such notice and other information

Landlord shall reimburse Tenant for the amount thereof until the total of all
such reimbursements is equal to the Sixth Floor Space Allowance (it being
understood that in no event shall Landlord be obligated to expend in excess of

Sixth Floor Space to Tenant until such lease expires or terminates and the
occupant of the Sixth Floor Space vacates the same. Landlord has advised Tenant
that such lease for the Sixth Floor Space is scheduled to terminate on June 30,
2000; however, Tenant agrees that if Landlord delivers vacant, broom-clean
possession of the Sixth Floor Space to Tenant prior to June 30, 2000, such
earlier date of delivery shall be the Sixth Floor Space Possession Date,
provided, that in no event shall such earlier date of delivery be earlier than
five (5) days after Landlord gives to Tenant notice of the date on which
Landlord anticipates that the Sixth Floor Space shall be so delivered to Tenant
(unless Tenant or anyone claiming under or through Tenant first occupies the
Sixth Floor Space for the performance of its work therein or any other purpose
prior to the giving of such notice by Landlord or the expiration of such 5-day
period). If any tenant in the Sixth Floor Space shall holdover beyond June 30,
2000, Landlord shall use reasonable efforts (including the prompt commencement
and diligent prosecution of summary proceedings) to terminate such holdover
tenancy.

Tenant shall have no claim against Landlord, and Landlord shall have no
liability to Tenant for any failure or delay to deliver possession of the Sixth
Floor Space pursuant to the terms hereof on the anticipated availability date or
any other specific date and the validity of the Lease, as amended hereby, shall
not be impaired under such circumstances nor shall the same be construed to
extend the Term.

            9. Expansion Option. Landlord and Tenant acknowledge and agree that
Article 45 of the Lease (Expansion Option) is null and void and of no further
force and effect.

this Amendment, and Tenant covenants and agrees to pay, hold harmless and
indemnify Landlord from and against any and all cost, expense (including
reasonable attorneys' fees and court costs), loss and liability for any
compensation, commissions or charges claimed by any broker or agent, other than
Insignia/Edward S. Gordon Company, Inc. and DLJ Realty Services, Inc., with
respect to this Amendment or the negotiation thereof if such claim or claims by
any such broker or agent are based in whole or in part on dealing with Tenant or
its representatives.

indemnify Tenant from and against any and all costs, expenses (including
reasonable attorneys' fees and court costs), loss and liability for any
compensation, commissions or charges in connection with this Amendment or the
negotiation thereof, claimed under any circumstances by Insignia/Edward S.
Gordon Company, Inc. or claimed by any other broker or agent if the claims by
such other brokers or agents are based in whole or part on dealings with

Services, Inc., such compensation, commissions or charges to which they are
entitled in connection with this Amendment pursuant to a separate agreement
between Landlord and said broker.

inure to the benefit of Landlord and Tenant and their respective permitted
successors and assigns.

            12. Entire Agreement. This Amendment represents the entire
understanding of the parties hereto with respect to the subject matter hereof.

            13. Ratification; Confirmation. As amended hereby, the Lease is
hereby ratified and confirmed in all respects and shall continue in full force
and effect. In the event of any conflict between the terms of this Amendment and
the terms of the Lease, the terms of this Amendment shall govern.

            14. Governing Law. This Amendment shall be governed by and construed
in accordance with the laws of the State of New Jersey, without giving effect to
the conflicts of law principles thereof.

each of which when taken together shall be deemed to be one and the same
instrument.
