        The foregoing rent schedule shall be subject to further amendment
should any Commencement Date for Expansion Spaces X, CC and/or DD occur on
dates other than as anticipated in the Twenty-Second Amendment or this
Twenty-Sixth Amendment, as applicable. When Expansion Spaces X, CC, and DD are
occupied by Tenant, Landlord and Tenant shall, at the request of either party,
execute a memorandum specifying the Commencement Date for each such expansion
space.

6.      Escalation Adjustment. Commencing on the Commencement Date applicable
to the particular expansion space, Tenant's proportionate share of increases in
Building Operating Costs payable under Paragraph 13. of the Lease shall be
increased to take such additional expansion space into consideration. The "Base
Year" for Expansion Spaces CC and DD shall be the calendar year 1996.

7.      Condition of Premises. Landlord will tender and Tenant agrees to accept
Expansion Spaces CC and DD in an "as-is" condition; however, Landlord shall
provide an allowance ("Construction Allowance") of $0.18286 times the number of
months in the respective term of the Lease for permanent leasehold improvements
Tenant may elect to install in Expansion Spaces CC and DD. As said Construction
Allowance is utilized by Tenant, payments and/or partial payments to Tenant
shall be made within thirty (30) days from Landlord's receipt of paid invoices.
Tenant shall, at its sole cost and expense, provide complete construction
documentation, including MEP engineered drawings. Tenant may utilize up to
Fourteen Thousand Nine Hundred Ninety-Eight and No/100 Dollars ($14,998.00)
[$2.00 per square foot of Rentable Area] of the Construction Allowance to
offset its cost for architectural services and the preparation of construction
documentation.

8.      Competitive Bids. For Expansion Spaces CC and DD, Landlord will seek
competitive bids from a minimum of three (3) general contractors which meet
Landlord's existing requirements from Landlord's approved bidding list mutually
agreed upon between Tenant and Landlord and provide Tenant copies of the bids.
In addition, only subcontractors approved by Landlord, according to Landlord's
current standards for such approval, will be permitted to work on the
mechanical, electrical and plumbing systems of the Building. Tenant shall be
allowed to participate in the selection of the successful bidder and Tenant
shall enter into a contract with the successful bidder.

9.      Americans with Disabilities Act. Landlord shall be responsible for
costs and implementation associated with compliance with the Americans with
Disabilities Act (the "ADA") for the Building and all points of access into the
Building ("the Landlord's ADA Work"). Tenant shall be responsible for all costs
and implementation associated with ADA compliance within Expansion Spaces CC
and DD.

10. Emergency Generator. Commencing October 1, 1996, Tenant shall be billed on 
a monthly basis for two (2) reserved permits at the prevailing monthly 
contract rates for the garage located south of the Building, plus state and 
local taxes, to cover the cost of the spaces upon which Tenant's emergency
generator ("Generator") is located. Tenant will be responsible for all repairs
and maintenance relating to the Generator (including diesel spills). Upon
expiration or termination of the Lease, Tenant shall remove the Generator from
the parking garage located south of the Building and repair any damaged caused
thereby at its sole cost and expense, unless said requirement is otherwise
waived by Landlord in writing. Tenant's use of such parking spaces for the
Generator shall be subject to all applicable terms and conditions of the Lease
as though such parking spaces were a part of the Leased Premises, specifically
including without limitation Tenant's indemnification obligations set forth in 
Paragraph 9 thereof. In addition, Tenant agrees to indemnify, protect, defend
and hold harmless Landlord and its partners, affiliated companies, officers,
directors, shareholders, employees and agents for, from and against all
liabilities, claims, judgments, diminution in value of the Building and
Building parking garage, fines, penalties, costs, damages or injuries to
persons, damages to property, losses, liens, causes of action, suits, judgments
and expenses (including court costs, attorneys' fees and costs of
investigation), of any nature, kind or description of any person or entity,
directly or indirectly, in whole or in part, arising out of, caused by or
resulting from (a) Tenant's use of the parking spaces for the Generator, and
any activity, work or other things done, permitted or suffered by Tenant or its
agents and employees in or about such parking spaces relating to or arising
from the Generator, including without limitation the release, storage,
transport or disposal of any petroleum products or any other hazardous
substances or materials regulated by law; and/or (b) any act, omission,
negligence or willful misconduct of Tenant or any of its agents, contractors,
employees, business invitees or licensees relating to the Generator.

11. Time of the Essence. Time is of the essence with respect to Tenant's
execution and delivery of this Twenty-Sixth Amendment to Landlord. If Tenant
fails to execute and deliver a signed copy hereof to Landlord by 5:00 p.m.,
November 30, 1996, it shall be deemed null and void and shall have no force or
effect, unless otherwise agreed in writing by Landlord.

12. Binding Effect. Except as modified by this Twenty-Sixth Amendment, the
terms and provisions of the Lease shall remain in full force and effect, and
the Lease, as modified hereby, shall be binding upon the parties hereto, their
successors and assigns. This Twenty-Sixth Amendment shall become effective only
after the full execution and delivery hereof by Landlord and Tenant.

        ACCORDINGLY, Landlord and Tenant enter into this Twenty-Sixth Amendment
as of November 29, 1996.
