the account of others. It is hereby expressly agreed that notwithstanding this
Agreement, U-Haul and such affiliates may continue to engage in such activities,

(except as expressly otherwise


                                       1

provided for herein) construed as making U-Haul an agent or employee of Owner or

shall have the sole and exclusive authority to fully manage the Property and
supervise and direct the business and affairs associated or related to the daily
operation thereof, and, to that end on behalf of Owner, to execute such

discretion, which discretion shall be exercised in good faith, to establish the
terms and conditions of occupancy by the tenants of the Property, and U-Haul is
hereby authorized to enter into rental agreements on behalf and for the account
of Owner with such tenants and to collect rent from such tenants. U-Haul may

Property; provided, however, that U-Haul agrees to secure the prior written
approval of Owner on all such expenditures in excess of $5,000.00 for any one
item, except monthly or recurring operating charges and/or emergency repairs if
in the opinion of U-Haul such emergency-related expenditures are necessary to
protect the Property from damage or to maintain services to the tenants as
called for in their respective leases.

      (d) PERSONNEL. U-Haul shall select all vendors, suppliers, contractors,
subcontractors and employees with respect to the Property and shall hire,

the payroll of U-Haul. Employees may include, but will not be limited to,
on-site resident managers, on-site assistant managers, and relief managers
located, rendering services, or performing activities on the Property in
connection with its operation and management. The cost of employing such persons
shall not exceed prevailing rates for comparable persons performing the same or
similar services with respect to real estate similar to the Property.

      (e) AGREEMENTS. U-Haul shall negotiate and execute on behalf of Owner such
agreements which U-Haul deems necessary or advisable for the furnishing of
utilities, services, concessions and supplies, for the maintenance, repair and
operation of the Property and such other agreements which may benefit the
Property or be incidental to the matters for which U-Haul is responsible
hereunder.

      (f) OTHER DECISIONS. U-Haul shall make all decisions in connection with
the daily operation of the Property.

      (g) REGULATIONS AND PERMITS. U-Haul shall comply in all material respects

keeping and bookkeeping with respect to all receipts and disbursements in
connection with the management and operation of the Property. The books, records
and accounts shall be maintained at the U-Haul office or at such other location
as U-Haul shall determine, and shall be available and open to examination and
audit quarterly by Owner, its representatives, any mortgagee of the Property,
and such mortgagee's representative. On or before thirty (30) days after the
close of each quarter, U-Haul shall cause to be prepared and delivered to Owner,
a monthly statement of receipts, expenses and charges, together with a statement
of the disbursements made by U-Haul during such period on Owner's behalf.

      (i) [Reserved].

                                       3
<PAGE>
      (k) LEGAL ACTIONS. U-Haul shall cause to be instituted, on behalf and in
the name of Owner, any and all legal actions or proceedings U-Haul deems
necessary or advisable to collect charges, rent or other income due to Owner
with respect to the Property and to oust or dispossess tenants or other persons
unlawfully in possession under any lease, license concession agreement or
otherwise, and to collect damages for breach thereof or default thereunder by
such tenant, licensee, concessionaire or occupant.

      (l) INSURANCE. U-Haul shall use its best efforts to assure that there is
obtained and maintained in force, fire, comprehensive liability and other
insurance policies in amounts generally carried with respect to similar
facilities. U-Haul may in its discretion obtain employee theft or similar
insurance in amounts and with such deductibles as U-Haul deems appropriate.
U-Haul shall promptly provide Owner with such certificates of insurance as Owner
may reasonably request in writing, evidencing such insurance coverage.

      (m) TAXES. During the term of this Agreement, U-Haul shall pay from
Owner's funds, prior to delinquency, all real estate taxes, personal property
taxes, and all other taxes assessed to, or levied upon, the Property. If
required by the holder of any note secured by the Property, U-Haul will set
aside, from Owner's funds, a reserve from each month's rent and other income
collected, in an amount required by said holder for purposes of payment of real
property taxes.

      (n) [RESERVED].

      (o) LIMITATIONS ON U-HAUL AUTHORITY. Notwithstanding anything to the
contrary set forth in this Section 2, U-Haul shall not, without obtaining the
prior written consent of Owner, (i) rent storage space in the Property by
written lease or agreement for a stated term in excess of one year, (ii) alter
the building or other structures of the Property in any material manner; (iii)
make any other agreements which exceed a term of one year and are not terminable
on thirty day's notice at the will of Owner, without penalty, payment or
surcharge; (iv) act in violation of any law; or (v) act in violation of any duty
or responsibility of Owner under any mortgage loan secured by the Property.

      (p) SHARED EXPENSES. Owner acknowledges that certain economies may be
achieved with respect to certain expenses to be incurred by U-Haul on behalf of
Owner hereunder if materials, supplies, insurance or services are purchased by
U-Haul in quantity for use not only in connection with the Property but in
connection with other properties owned or managed by U-Haul or its affiliates.
U-Haul shall have the right to purchase such materials, supplies, insurance
and/or services in its own name and charge Owner a pro rata allocable share of
the cost of the foregoing; provided, however, that the pro rata cost of such
purchase to Owner shall not result in expenses greater than would otherwise be
incurred at competitive prices and terms available in the area where the


                                       4
<PAGE>
Property is located; and provided further, U-Haul shall give Owner access to
records so Owner may review any such expenses incurred.

      (q) DEPOSIT OF GROSS REVENUES. All Gross Revenues (as hereinafter defined)
shall be deposited into a bank account maintained by U-Haul (or its parent
company) as for the benefit of the Owner. To the extent that the Gross Revenues
are deposited into a collective account maintained by U-Haul (or its parent
company) for the benefit of multiple property owners, U-Haul (or its parent
company) shall reconcile such account daily and maintain such records as shall
clearly identify each day the respective interest of each owner in such
collective account. Gross Revenues of the Owner shall be applied first to the
repayment of Owner's senior debt with respect to the Property, and then to
U-Haul in reimbursement of expenses and for management fees as provided under
Section 4 below.

3. Duties of Owner.

      Owner hereby agrees to cooperate with U-Haul in the performance of
U-Haul's duties under this Agreement and to that end, upon the request of
U-Haul, to provide, at such rental charges, if any, as are deemed appropriate,
reasonable office space for U-Haul employees on the premises of the Property and
to give U-Haul access to all files, books and records of Owner relevant to the
Property. Owner shall not unreasonably withhold or delay any consent or
authorization to U-Haul required or appropriate under this Agreement.

4. Compensation of U-Haul.

      (a) MANAGEMENT FEE. Owner shall pay to U-Haul as the full amount due for
the services herein provided a fee (the "Management Fee") equal to six percent
(6%) of the "Gross Revenue" derived from or connected with the Property so
managed by U-Haul hereunder. The term "Gross Revenue" shall mean all receipts
(excluding security deposits unless and until Owner recognizes the same as
income) of Owner (whether or not received by U-Haul on behalf or for the account
of Owner) arising from the operation of the Property, including without
limitation, rental payments of lessees of space in the Property, vending machine
or concessionaire revenues, maintenance charges, if any, paid by the tenants of
the Property in addition to basic rent, parking fees, if any, and all monies
whether or not otherwise described herein paid for the use of the Property.
"Gross Revenue" shall be determined on a cash basis. The Management Fee shall be
paid promptly at the end of each calendar quarter and shall be calculated on the
basis of the "Gross Revenue" of such preceding quarter. The Management Fee shall
be paid to each U-Haul property manager herein identified based on the Gross
Revenue of each respective Property for which such property manager is
responsible as set forth on Exhibit A hereto. Each property manager agrees that
its monthly Management Fee shall be


                                       5
<PAGE>
subordinate to that month's principal balance and interest payment on any first
lien position mortgage loan on the Property.

      It is understood and agreed that the Management Fee will not be reduced by
the cost to Owner of those employees and independent contractors engaged by or
for Owner, including but not limited to the categories of personnel specifically
referred to in Section 2(d). Except as provided in this Section 4, it is further
understood and agreed that U-Haul shall not be entitled to additional
compensation of any kind in connection with the performance by it of its duties
under this Agreement.

      (b) REIMBURSEMENT OF EXPENSES. In addition to the Management Fee described
above, U-Haul shall be entitled to reimbursement from Owner, on a quarterly
basis, for all out-of-pocket expenses incurred by U-Haul hereunder in connection
with the management and operation of the Property, including, without
limitation, taxes, insurance, operational expenses, overhead, litigation and
dispute resolution related expenses, capital improvement expenses, and costs of
sales.

5. Use of Trademarks, Service Marks and Related Items.

      Owner acknowledges the significant value of the "U-Haul" name in the
operations of Owner's property and it is therefore understood and agreed that
the name, trademark and service mark, "U-Haul", and related marks, slogans,
caricatures, designs and other trade or service items shall be utilized for the
non-exclusive benefit of Owner in the rental and operation of the Property, and
in comparable operations elsewhere. It is further understood and agreed that
this name and all such marks, slogans, caricatures, designs and other trade or
service items shall remain and be at all times the property of U-Haul and its
affiliates, and that, except during the term hereof and as expressly provided
herein, Owner shall have no right whatsoever therein. Owner agrees that during
the term of this agreement the sign faces at the property will have the name
"U-Haul." The U-Haul sign faces will be paid for by Owner. Upon termination of
this agreement at any time for any reason, all such use by and for the benefit
of Owner of any such name, mark, slogan, caricature, design or other trade or
service item in connection with the Property shall, in any event, be terminated
and any signs bearing any of the foregoing shall be removed from view and no
longer used by Owner. In addition, upon termination of this Agreement at any
time for any reason, Owner shall not enter into any new leases of Property using
the U-Haul lease form or use other forms prepared by U-Haul. It is understood
and agreed that U-Haul will use and shall be unrestricted in its use of such
name, mark, slogan, caricature, design or other trade or service item in the
management and operation of other storage facilities both during and after the
expiration or termination of the term of this Agreement.

6. Termination.


                                       6
<PAGE>
      Owner or U-Haul may terminate this Agreement with or without cause by
giving not less than thirty days' written notice to the other party pursuant to
Section 11 hereof. In addition, if Owner fails to pay U-Haul any amounts owed
under this Agreement when due, U-Haul may terminate this Agreement by giving
Owner not less than ten days written notice pursuant to Section 11 hereof.
Notwithstanding the foregoing, however, U-Haul shall not resign as property
manager of the Property until a nationally recognized and reputable successor
property manager is available and prepared to assume property management
responsibilities with respect to the Property in question Upon termination of
this Agreement, U-Haul shall promptly return to Owner all monies, books, records
and other materials held by U-Haul for or on behalf of Owner. In addition, if
U-Haul has contracted to advertise the Property in the Yellow Pages, Owner
shall, at the option of U-Haul, continue to be responsible for the cost of such
advertisement and shall either (i) pay U-Haul the remaining amount due under
such contract in a lump sum; or (ii) pay U-Haul monthly for the amount due under
such contract.

7. Indemnification.

      U-Haul hereby agrees to indemnify and hold Owner, all persons and
companies affiliated with Owner, and all officers, shareholders, directors,
employees and agents of Owner and of any affiliated companies or persons
(collectively, the "Indemnified Persons") harmless from any and all costs,
expenses, attorneys' fees, suits, liabilities, judgments, damages, and claims in
connection with the management of the Property and operations thereon (including
the loss of use thereof following any damage, injury or destruction), arising
from any cause or matter whatsoever except to the extent attributable to the
willful misconduct or gross negligence on the part of the Indemnified Persons.

8. Assignment.

      This Agreement may be assigned by Owner in connection with any mortgage
loan on the Property, whether pursuant to a conditional or unconditional,
absolute assignment. U-Haul shall have the right to assign this Agreement to an
affiliate or a wholly or majority owned subsidiary; provided, however, any such
assignee must assume all obligations of U-Haul hereunder, Owner's rights
hereunder will be enforceable against any such assignee and U-Haul shall not be
released from its liabilities hereunder unless Owner shall expressly agree
thereto in writing.

property manager hereunder shall be liable for the acts or omissions of any
other property manager hereunder. Each property manager shall use its best
efforts to assist Owner in fulfilling Owner's obligations arising under any loan
to Owner that is secured by the Property, including but not limited to preparing
and providing financial and accounting reports, and maintaining the Property.
Each property manager agrees that it will perform its obligations hereunder
according to reasonable industry standards, in good faith, and in a commercially
reasonable manner. U-Haul agrees that, in discharging its duties hereunder, it
will not have any relationship with any of its affiliates that would be less
favorable to Owner than would reasonably be available in a transaction with an
unaffiliated party.
