            (c) From and after the Plaza III Sixth Floor Space Commencement Date
      until the last day of the Plaza III Sixth Floor Term, Tenant's Tax Share
      shall be increased by 2.62% and Tenant's Expense Share shall be increased

Landlord shall make twenty (20) un-reserved parking spaces ("Plaza III Parking

Parking Areas of the Property as Landlord shall periodically designate for

the same terms and conditions as set forth with respect to Tenant's Parking

determines that there is excess parking capacity in the Parking Areas of the
Property, Landlord agrees to cooperate with Tenant to provide additional
unreserved parking spaces to Tenant in a number and in locations to be
determined by Landlord in its sole discretion. Notwithstanding the foregoing,
Landlord shall have no liability to Tenant for any failure to provide Tenant
with any additional parking spaces and neither the validity of this Amendment
nor of the Lease shall be impaired by reason of such failure.

payment of basic annual rent and Taxes and Operating Expenses from the Plaza III
Sixth Floor Space Possession Date through and including the day immediately

amounts payable with respect to the Plaza III Sixth Floor Space from and after
the Plaza III Sixth 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 Plaza III Sixth Floor Space
from and after the Plaza III Sixth Floor Space Commencement Date at the times
and in the manner set forth in the Lease (as amended hereby). If the Plaza III
Sixth Floor Space Commencement Date falls on any day other than the first day of
a month, then the basic annual rent for the Plaza III Sixth 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 Plaza III Sixth 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 Plaza III Sixth 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.

            (g) Tenant shall be entitled to reimbursement of up to an amount
equal to $231,160.44 (the "Plaza III Sixth Floor Space Allowance") for Hard
Costs and Soft Costs paid by Tenant in connection with the preparation of the
Plaza III Sixth Floor Space for Tenant's occupancy; provided, that Tenant shall
not be entitled to reimbursement from the Plaza III Sixth Floor Space Allowance
for Soft Costs to the extent such Soft Costs exceed an amount (the "Plaza III
Sixth Floor Space Soft Costs Maximum") equal to $57,790.11. 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 Tenant is
seeking reimbursement have been paid. On or about August 1, 2001 (but in no
event later than August 31, 2001), provided Tenant has submitted such notice and
other information to Landlord not later than July 1, 2001 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 Plaza III Sixth Floor Space Allowance (it being
understood that in no event shall Landlord be obligated to expend in excess of
the Plaza III Sixth Floor Space Allowance or reimburse Tenant for Soft Costs in
excess of the Plaza III Sixth Floor Space Soft Costs Maximum). Anything to the
contrary contained herein notwithstanding, Landlord shall have the right to
withhold $23,000 from the Plaza III Sixth 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 Plaza III Sixth Floor
Space and the disk carrying the same in accordance with Section 6.01(11) of the

Space Possession Date, Tenant shall accept the Plaza III Sixth Floor Space in
its "as is" condition and Landlord shall have no obligation to perform any work

All installations, materials and work which may be undertaken by Tenant to
prepare, equip, decorate and furnish the Plaza III Sixth 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.

            5. Lease Extension of Plaza III Sixth Floor Space. (a)
Notwithstanding anything contained in the Lease or this Amendment to the
contrary, Landlord and Tenant acknowledge that the American Institute of
Certified Public Accountants or its successor in interest ("AICPA") has the
option to expand its premises to include the Plaza III Sixth Floor Space ("AICPA
Option").

                  (b) On or before September 30, 2004 Landlord shall notify
Tenant as to whether AICPA has exercised the AICPA Option. If AICPA has
exercised the AICPA Option, then the Plaza III Sixth Floor Term shall expire
without further notice to Tenant on the Plaza III Sixth Floor Space Expiration
Date. If AICPA has not exercised the AICPA Option, then the Plaza III Sixth
Floor Space Term shall be automatically extended until the Expiration Date on
all of the terms and conditions of the Lease as amended by this Amendment. If
the Plaza III Sixth Floor Space Term shall be so extended, Landlord and tenant
shall execute an instrument confirming such extension, but the failure of the
parties to execute such instrument shall not affect the effectiveness of such
extension of the Plaza III Sixth Floor Space Term.

                  (c) If the Plaza III Sixth Floor Space Term is so extended
until the Expiration Date, then Tenant shall be entitled to reimbursement of up
to an amount equal to $358,534.56 (the "Second Plaza III Sixth Floor Space
Allowance") for Hard Costs and Soft Costs paid by Tenant in connection with the
preparation of the Plaza III Sixth Floor Space for Tenant's occupancy; provided
that Tenant shall not be entitled to reimbursement from the Second Plaza III
Sixth Floor Space Allowance for Soft Costs to the extent such Soft Costs exceed
an amount (the "Second Plaza III Sixth Floor Space Soft Costs Maximum") equal to
$89,633.64. 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 from the Plaza III Sixth Floor Space
Allowance, the Second Plaza III Sixth Floor Space Allowance or otherwise, (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 Tenant is
seeking


                                      -5-
<PAGE>

reimbursement have been paid. On or about June 30, 2005 (but in no event later
than July 31, 2005), provided that Tenant has submitted such notice and other
information to Landlord not later than May 31, 2005, and provided the
certificates and other deliveries made therewith are correct, Landlord shall
reimburse Tenant for the amount thereof until the total of such all
reimbursements is equal to the Second Plaza III Sixth Floor Space Allowance (it
being understood that in no event shall Landlord be obligated to expend in
excess of the Second Plaza III Sixth Floor Space Allowance or reimburse Tenant
for Soft Costs in excess of the Second Plaza III Sixth Floor Space Soft Costs
Maximum). Anything to the contrary contained herein notwithstanding, Landlord
shall have the right to withhold $36,000 from the Second Plaza III Sixth 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 Second Plaza III Sixth Floor Space and the disk carrying the
same in accordance with Section 6.01(11) of the Lease.

            (d) If AICPA exercises the AICPA Option and Tenant shall hold over
in the Plaza III Sixth Floor Space after the Plaza III Sixth Floor Space
Expiration Date, such tenancy shall be deemed a month-to-month tenancy, which
tenancy may be terminated as provided by applicable law. During such tenancy,
Tenant agrees to (i) pay to Landlord, each month, the greater of the fair market
rental value for the Plaza III Sixth Floor Space or the Applicable Percentage
of (x) the basic annual rent and (y) all additional rent payable by Tenant for
the last month of the Plaza III Sixth Floor Space Term and (ii) be bound by all
of the terms, covenants and conditions specified in the Lease (as amended by
this Amendment). In addition to Tenant's obligations set forth in clauses (i)
and (ii) of this Paragraph 5(d) or elsewhere in the Lease, Tenant shall be
liable for all consequential damages suffered by Landlord in connection with
Tenant holding over in the Plaza III Sixth Floor Space.

            6. Existing Tenant. Tenant acknowledges that the Plaza III Sixth
Floor Space is subject to an existing lease and Landlord will not be able to
deliver the Plaza III Sixth Floor Space to Tenant until such lease expires or
terminates and the occupant of the Plaza III Sixth Floor Space vacates the same.
Landlord has advised Tenant that such lease for the Plaza III Sixth Floor Space
is scheduled to terminate on April 30, 2000; however, Tenant agrees that if
Landlord delivers vacant, broom-clean possession of the Plaza III Sixth Floor
Space to Tenant prior to April 30, 2000, such earlier date of delivery shall be
the Plaza III 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 Plaza
III Sixth Floor Space shall be so delivered to Tenant (unless Tenant or anyone
claiming under or through Tenant first occupies the Plaza III 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 Plaza III Sixth Floor Space shall holdover beyond April 30, 2000,
Landlord shall use reasonable efforts (including the prompt commencement and
diligent prosecution of summary proceedings) to terminate such holdover tenancy.
Notwithstanding anything to contrary contained in the Lease, Tenant agrees that
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 Plaza
III 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


                                      -6-

            (b) Tenant hereby agrees to pay to Landlord basic annual rent for

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 Plaza III Fourth Floor Space Term.

which they are entitled in connection with this Amendment pursuant to a separate

expiration of such ninety (90) day period. If this Amendment is terminated
pursuant to this Paragraph 16, Tenant, shall, immediately upon such termination,
vacate any space occupied by Tenant pursuant to the Amendment and surrender such

or (c) DLJ's and Direct's agreement to be bound by Paragraph 2 of this
