            (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

      (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 remitted by U-Haul (or its parent company) on a daily
      basis to a bank account maintained by UBS Warburg Real Estate Investments
      Inc. ("Lender") (or an affiliate thereof) and the funds therein shall be
      applied in the manner specified in that Cash Management Agreement dated
      the date hereof among Owner, U-Haul and Lender. U-Haul shall maintain such
      records and systems as are necessary or appropriate to enable U-Haul to
      clearly identify the amount of Gross Revenue generated by each Property on
      a daily basis.

      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. Throughout the term hereof, Owner shall not permit
      the Property to be operated under any name other than "U-Haul" (R).

      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. U-Haul shall not offset or reduce
      the amount of the Management Fee payable to it at any time hereunder in
      exchange for a reduction in the amount rent due from U-Haul to Owner
      pursuant to any lease agreement between U-Haul and Owner. 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

                                       5
<PAGE>
      agrees that its monthly Management Fee shall be 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 CERTAIN 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.

            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.

            Owner hereby agrees to indemnify and hold each of U-Haul, all
      persons and companies affiliated with U-Haul, and all officers,
      shareholders, directors, employees and agents of U-Haul 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 (including the loss of use thereof following
      any damage, injury or destruction), arising from any cause except for the
      willful misconduct or gross negligence on the part of the Indemnified
      Persons. In addition, no Indemnified Person shall be liable for any error
      of judgment or for any mistake of fact or law, or for anything which it
      may do or refrain from doing hereafter, except in cases of willful
      misconduct or gross negligence. U-Haul hereby agrees to indemnify and hold
      Owner harmless from any and all costs, expenses, attorneys' fees, suits,
      liabilities, judgments, damages and claims in connection with the
      management of the Property arising from the willful misconduct of, gross

      addition, U-Haul shall not be liable to Owner for the acts or omissions of
      U-Haul's officers, shareholders, directors, employees, and agents except
      for U-Haul's own gross negligence or willful misconduct.

      of such property manager, as more specifically described on Exhibit A
      hereto, and no individual 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 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.
