charges relating to the Premises: taxes, special assessments, ground rents,
insurance premiums (other than premiums arising out of Section 2.1(b) for which

Manager to coordinate the placement of property insurance upon the Premises

such insurance or self-insurance for indemnity against any loss or damage to the
Premises or to any tenant insurance, except in the case of Property Manager's
negligence (when Property Manager is acting outside of the scope of its
employment or in violation of this Agreement), gross negligence or willful
misconduct, or as otherwise provided herein. To the extent that policies shall
be procured, Owner shall obtain waivers of subrogation in favor of Property
Manager under such policies. Property Manager shall be an insured as real estate
manager on Owner's liability policy.

            3.3 With respect to liabilities arising out of the use and operation
of the Premises and arising under this Agreement except for liabilities arising
out of section 2.1(b), Owner shall indemnify and save harmless Property Manager
from and against all claims, losses and liabilities (including, without
limitation, all costs and attorneys fees and expenses incurred in connection
therewith) resulting from damage to property or injury to, or death of, persons,
defamation and false arrest (including, but not limited to, the property and
persons of the parties hereto and their agents, contractors, subcontractors and

Manager's negligence when Property Manager is acting outside of the scope of its
employment or in violation of this Agreement), gross negligence or willful
misconduct, or (ii) Owner or Owner's agents, employees, contractors or

                                  ARTICLE IV
                            PROPERTY MANAGER'S FEES

                       AND COMMISSIONS:  REIMBURSEMENTS

            4.1 As management fees for the services performed pursuant to
Article II, Owner agrees to pay Property Manager on the basis specified in
Exhibit A, paragraph 6. Said fee shall be payable monthly on the tenth (10th)
day of the month and shall be based on receipts from the previous calendar
month. Property Manager shall withdraw said fee from the operating account for
the Premises and shall account for same as provided for in Section 2.2 hereof.
If fees are based on rent or income, it is understood that they shall be
applicable to rent or income actually collected, including parking receipts, and
that there shall be excluded therefrom: direct charges for taxes, insurance,
fuel, electricity, water, labor or any other expense in connection with the
operation and maintenance of the Premises which are paid directly by a tenant to
any taxing authority, utility or service company; fire loss proceeds, capital
improvements, remodeling and tenant change costs (including any overhead factor
payable by tenants); amortization for tenant work, security deposits; however,
tax, utility, service charges and operating expense escalation charges required
to be calculated, billed and collected from individual tenants by Property
Manager will be included in collectively income for the purpose of calculating
management fee. Management fees shall be paid based on actual receipts, not
estimates. Owner shall be entitled to pay Property Manager directly rather than
permitting Property Manager to pay itself out of the Bank Account. To the extent
any amounts are refunded to tenants, gross rent shall be reduced accordingly.
Any rent paid more than thirty (30) days in advance or sales proceeds shall be
excluded from gross rent.

            4.2 As leasing commissions, if any, for new leases secured pursuant
to Section 2.6, including renewals, expansions or extensions exercised during
the term of this Agreement, Owner agrees to pay Property Manager at the rate
specified in Exhibit A, paragraph 7. A commission will be paid on direct leases
signed with subtenants for the period following the expiration date of the
original tenant's master lease. If a new lease contains a cancellation option
exercisable by the tenant and the cancellation fee does not include an amount
for the unamortized leasing commission remaining at the cancellation date, a
leasing commission will be paid on the initial term, which is prior to such
termination date, with the commission for the balance of the lease term payable
when and if such Tenant does not terminate the lease on or before such date as
set forth herein. Commissions will be based on base rents and pre-determined
fixed escalations payable to Owner only and will exclude: percentage rent;
variable escalations; operating expense escalations; real estate tax
escalations; any portion of said base rent attributable to parking; and free
rent. In the event a lease provides that the tenant is to pay directly for some
or all of the operating expense and/or real estate taxes associated with its
space, then for purpose of calculating the commissions listed in Exhibit A, the
tenant's annual base rent shall be increased by an amount equivalent to the
estimated annual expenses that will be paid by tenant during the first year of
its lease as determined by Owner. No commission will be due for any portion of a
lease term that

<PAGE>
                                       13


exceeds ten (10) years. Leasing commissions for new leases and expansions shall
be paid fifty percent (50%) within thirty (30) days after lease execution by all
parties and fifty percent (50%) within thirty (30) days after lease commencement
and actual occupancy in the event of a renewal or extension, any commission
payment due shall be paid within thirty (30) days of the execution of the
renewal or extension documentation. When leases are negotiated on behalf of
tenant by outside brokers, Property Manager shall cooperate with such brokers,
Property Manager shall be responsible for paying all commissions to such outside
brokers, and all commissions to such outside broker shall be subject to the
written approval of Owner. The cost of all approved commissions will be borne by
Owner, unless already paid to Property Manager in accordance with the terms
hereof. Property Manager will assist Owner in negotiating the terms of fees to
outside brokers, and will submit recommendations to Owner regarding the
percentage rate for outside brokerage commissions In conjunction with the budget
submissions provided for in Section 2.5.

            4.3 To the extent expressly identified in the Approved Budget, Owner
shall be responsible to reimburse Property Manager for the following expenses or
costs incurred by or on behalf of Property Manager in connection with the
management and leasing of the Premises. At Owner's option such expenses can come
out of be paid from the established Bank Account.

            (a) Cost of gross salary, wages, bonuses, payroll taxes, insurance,
worker's compensation, pension benefits and any other benefits of Property
Manager, property management clerical support, engineering personnel, and
engineering clerical support as allocated to the Premises.

            (b) Necessary general accounting and reporting services, as

for property management purposes.

            (d) Cost of continuing education for personnel allocated to the
      Premises.

            (e) Cost of parking for personnel allocated to the Premises.

            (f) Necessary cost of telecommunications, couriers, and postage
      allocated to the Premises.

            All of the enumerated items in section 4.3 must be at commercially
            reasonable rates.

monetary defaults and fifteen (15) days following receipt of written notice from
Owner specifying such breach, default or non-compliance for non-monetary
