      maturity of the Loan.

                  (iv) Determination of Net Capital Proceeds. Prior to the
      occurrence of a Triggering Event (or, in the event of a Default
      Occurrence, within a reasonable time thereafter), the "Net Capital
      Proceeds" resulting from such Triggering Event shall be determined as
      follows:

                        (A) Net Capital Proceeds From Sale or Financing. Except
      as provided in Section 2(h)(iv)(B) below, in the event of a Sale or
      Financing, "Net Capital Proceeds" shall be the amount which is equal to:
      (I) either (x) the Gross Capital Proceeds (as hereinafter defined)
      realized from the Project, or (y) the fair market value of the Project
      determined pursuant to Section 2(h)(v) below, if Holder in its discretion
      requires such a determination, minus (II) the sum of: (aa) reasonable
      brokerage commissions (excluding any payments to any Affiliate of Maker to
      the extent such payments exceed those which would have been due as
      commissions to a non-Affiliate broker rendering identical services), title
      insurance premiums, documentary transfer taxes, escrow fees and recording
      charges, appraisal fees, reasonable attorneys' fees and costs, and sales
      taxes (if any), in each case actually paid or payable by Maker in
      connection with the Sale or Financing, plus (bb) all payments of principal
      and Deferred Interest paid to Holder an account of this Note from the
      proceeds of such Sale or Financing, plus (cc) an amount equal to all
      payments of principal and interest on the Senior Loan made from the
      proceeds of such Sale or Financing, plus (dd) any amount paid as Yield
      Maintenance Premium as a result of such Sale or Financing. For purposes of
      this Section 2(h), "Gross Capital Proceeds" shall mean the gross proceeds
      of whatever form or nature payable directly or indirectly to or for the
      benefit or account of Maker in connection with such Sale or Financing,
      including, without limitation: cash; the outstanding balance of any
      financing which will remain as a lien or encumbrance against the Project
      or any portion thereof following such Sale or Financing (but only in the
      case of a Sale, and not in the case of an encumbrance); and the cash
      equivalent of the fair market value of any non-cash consideration,
      including the present value of any promissory note received as part of the
      proceeds of such Sale or Financing (valued at a market rate of interest,
      as determined by an independent investment banker designated by Holder).

                        (B) Net Capital Proceeds In Connection With a Default or
      Maturity Occurrence. In the event of a Default Occurrence or the Maturity
      Occurrence when no Sale or Financing has occurred, the "Net Capital
      Proceeds" shall equal: (I) the fair market value of the Project determined
      as of the date of such Triggering Event in accordance with Section 2(h)(v)
      below, minus (II) the sum of (aa) the outstanding principal balance plus
      Deferred Interest on the Note plus (bb) the outstanding principal balance
      of, and accrued but unpaid interest on, the Senior Loan.


                                       9
<PAGE>

                  (v) Determination of Fair Market Value. The fair market value
      of the Project shall be determined for purposes of this Note as follows:

                        (A) Partial Sale. In the event of a Sale of a portion of
      the Project, Holder shall select an experienced, and reputable appraiser
      to prepare a written appraisal report of the fair market value of the
      Project in accordance with clause (C) below, and the appraised fair market
      value submitted to Holder by such appraiser shall be conclusive for
      purposes of this Note.

                        (B) Other Occurrences. In all other circumstances the
      fair market value of the Project shall be deemed to equal the result of
      dividing the Net Cash Flow Before Debt Service for the immediately
      preceding fiscal year by ten percent (10%). However, if the Net Cash Flow
      Before Debt Service for the immediately preceding fiscal year has been
      lowered because of unusually high Operating Expenses during such fiscal
      year the fair market value of the Project may, at the option of the Maker
      be determined by dividing by ten percent (10%) the mean average of the Net
      Cash Flow Before Debt Service of the Project for the 3 immediately
      preceding fiscal years of the Project.

                        (C) Appraisal Standards and Assumptions. In making any
      determination by appraisal of fair market value, the appraiser(s) shall
      assume that the improvements then located on the Project constitute the
      highest and best use of the property. If the Triggering Event is a Sale or
      Financing, the appraiser(s) shall take the sales price into account,
      although such sales price shall not be determinative of fair market value.
      Each appraiser selected hereunder shall be an independent MAI-designated
      appraiser with not less than ten years' experience in commercial real
      estate appraisal in the general geographical area where the Project is
      located.

                  (vi) Effect on Holder's Approval Rights. Nothing contained in
      this Section 2(h) shall be deemed or construed to waive, restrict, impair,
      or in any manner affect Holder's rights hereunder or under any provisions
      of the Debt Papers to consent (or withhold its consent) to: any prepayment
      of the Loan in whole or in part; sales or other transfers of all or any
      portion of the Project or any interest therein; sales or other transfers
      of any ownership interests in Maker; any refinancing of all or any portion
      of the Loan; any junior financing; or, any other matters which require
      Holder's consent.

                  (vii) Statement. Books and Records. With each payment of
      Capital Proceeds Contingent Interest, Maker shall furnish to Holder a
      statement setting forth Maker's proposed calculation of, Net Capital
      Proceeds and Capital Proceeds Contingent Interest and shall provide a
      detailed breakdown of all items necessary for such calculation. For a
      period of five years after each payment of Capital Proceeds Contingent
      Interest, Maker shall keep and maintain full and accurate books and
      records adequate to correctly reflect each such item. Said books and
      records shall be available for Holder's inspection, copying and audit
      during reasonable business hours following reasonable notice for the
      purpose of verifying the accuracy of the payments made on account of
      Capital Proceeds Contingent Interest. The costs of any such audit will be
      paid by Holder, except that Maker shall pay all reasonable costs and
      expenses of any such audit which


                                       10
<PAGE>

      discloses that any amount properly payable by Maker to Holder hereunder
      exceeded by five percent (5%) or more the amount actually paid and
      initially reported by maker as being payable with respect thereto.

                  (viii) Negative Capital Proceeds Contingent Interest.
      Notwithstanding any other provision of this Agreement, Holder shall not be
      responsible or liable in any respect to Maker or any other Person for any
      reduction in the fair market value of the Project or for any contingency,
      condition or occurrence that might result in a negative number for Capital
      Proceeds Contingent Interest. If at any time it is calculated, Capital
      Proceeds Contingent Interest shall be a negative amount, no Capital
      Proceeds Contingent Interest shall at that time be payable to Holder, but
      Holder shall in no way be liable for any such negative amount and there
      shall be no deduction or offset for such negative amount at any time when
      Capital Proceeds Contingent Interest shall be subsequently calculated.

                  (ix) No payment of Capital Proceeds Contingent Interest may,
      when added to all other payments of interest or payments construed as
      interest, shall exceed the Highest Lawful Rate.

      3. Usury Savings Clause. The provisions of this Section 3 shall govern and
control over any irreconcilably inconsistent provision contained in this Note or
in any other document evidencing or securing the indebtedness evidenced hereby.
The Holder hereof shall never be entitled to receive, collect, or apply as
interest hereon (for purposes of this Section 3, the word "interest" shall be
deemed to include Basic Interest, Additional Interest and any other sums treated
as interest under applicable law governing matters of usury and unlawful
interest), any amount in excess of the Highest Lawful Rate (hereinafter defined)
and, in the event the Holder ever receives, collects, or applies as interest any
such excess, such amount which would be excessive interest shall be deemed a
partial prepayment of principal and shall be treated hereunder as such; and, if
the principal of this Note is paid in full, any remaining excess shall forthwith
be paid to Maker. In determining whether or not the interest paid or payable,
under any specific contingency, exceeds the Highest Lawful Rate, Maker and the
Holder shall, to the maximum extent permitted under applicable law, (i)
characterize any nonprincipal payment as an expense, fee, or premium rather than
as interest, (ii) exclude voluntary prepayments and the effects thereof, and
(iii) spread the total amount of interest throughout the entire contemplated
term of this Note; provided, that if this Note is paid and performed in full
prior to the end of the full contemplated term hereof, and if the interest
received for the actual period of existence hereof exceeds the Highest Lawful
Rate, the Holder shall refund to Maker the amount of such excess or credit the
amount of such excess against the principal of this Note, and, in such event,
the Holder shall not be subject to any penalties provided by any laws for
contracting for, charging, or receiving interest in excess of the Highest Lawful
Rate.

      4. Payments.

            (a) Interest and Principal. Maker promises to pay to the Holder
      hereof Basic Interest, Deferred Interest and Additional Interest as, in
      the respective amounts, and at the respective times provided in Section 2
      hereinabove. Maker also agrees that, on the Maturity Date, Maker will pay
      to the Holder the entire principal balance of this Note then


                                       11
<PAGE>

      outstanding, together with all Basic Interest (including, without
      limitation, Deferred Interest), and Additional Interest accrued hereunder
      and not theretofore paid. Each payment of principal of, Basic Interest
      (including, without limitation, Deferred Interest), and Additional
      Interest on, or any other amounts of any kind with respect to, this Note
      shall be made by the Maker to the Holder hereof at its office in Phoenix,
      Arizona (or at any other place which the Holder may hereafter designate
      for such purpose in a notice duly given to the Maker hereunder), not later
      than noon, Eastern Standard Time, on the date due thereof; and funds
      received after that hour shall be deemed to have been received by the
      Holder on the next following business day. Whenever any payment to be made
      under this Note shall be stated to be due on a date which is not a
      business day, the due date thereof shall be extended to the next
      succeeding business day, and interest shall be payable at the applicable
      rate during such extension.

            (b) Late Payment Charges. If any amount of Interest, principal or
      any other charge or amount which becomes due and payable under this Note
      is not paid and received by the Holder within five business days after the
      date it first becomes due and payable, Maker shall pay to the Holder
      hereof a late payment charge in an amount equal to five percent (5%) of
      the full amount of such late payment, whether such late payment is
      received prior to or after the expiration of the ten-day cure period set
      forth in Section 8(a). Maker recognizes that in the event any payment
      secured hereby (other than the principal payment due upon maturity of the
      Note, whether by acceleration or otherwise) is not made when due, Holder
      will incur extra expenses in handling the delinquent payment, the exact
      amount of which is impossible to ascertain, but that a charge of five
      percent (5%) of the amount of the delinquent payment would be a reasonable
      estimate of the expenses so incurred. Therefore, if any such payment is
      not received when due and payable, Maker shall without prejudicing or
      affecting any other rights or remedies of the trustee under those certain
      Junior Deeds of Trust (or Junior Mortgages, or Junior Deeds to Secure
      Debt), Assignment of Leases and Rents, Security Agreement, Financing
      Statement and Fixture Filing of even date herewith or Holder pay to Holder
      to cover expenses incurred in handling the delinquent payment, an amount
      calculated at five percent (5%) of the amount of the delinquent payment.

            (c) No Prepayment. Maker shall have the right to prepay this Note at
      any time, but only subject to the requirements and conditions set forth
      below. If under any circumstances whatsoever (other than pursuant to
      Section 3 above) this Note is paid in whole or in part, whether
      voluntarily, following acceleration after the occurrence of an Event of
      Default, with the consent of Holder, by Holder's application of any
      condemnation or insurance proceeds to amounts due under the Note, by
      operation of law or otherwise, and whether or not such payment prior to
      the Stated Maturity Date results from the Holder's exercise of its rights
      to accelerate the indebtedness evidenced hereby, then Maker shall pay to
      the Holder the Yield Maintenance Premium (defined hereinbelow) in addition
      to paying the entire unpaid principal balance of this Note and all
      Interest which has accrued but is unpaid except with the written consent
      of the Holder.

      A Yield Maintenance Premium in an amount equal to the greater of (A) one
percent (1.0%) of the principal amount being prepaid, and (B) the positive
excess of (1) the present value ("PV") of all future installments of principal
and interest due pursuant to Section 4(a) of this


                                       12
<PAGE>

Note absent any such prepayment, including the principal amount due at the
Stated Maturity Date (collectively, "All Future Payments"), discounted at an
interest rate per annum equal to the sum of (a) the Treasury Constant Maturity
Yield Index published during the second full week preceding the date on which
such Yield Maintenance Premium is payable for instruments having a maturity
coterminous with the remaining term of this Note, and (b) One Hundred Forty
(140) basis points, over (2) the then outstanding principal balance hereof
immediately before such prepayment [(PV of All Future Payments) (Principal
balance at the time of prepayment) = Yield Maintenance Premium]. "Treasury
Constant Maturity Yield Index" shall mean the average yield for "This Week" as
reported by the Federal Reserve Board in Federal Reserve Statistical Release
H.15 (519). If there is no Treasury Constant Maturity Yield Index for
instruments having a maturity coterminous with the remaining term of this Note,
then the index shall be equal to the weighted average yield to maturity of the
Treasury Constant Maturity Yield Indices with maturities next longer and shorter
than such remaining average life to the maturity, calculated by averaging (and
rounding upward to the nearest 1/100 of 1% per annum, if the average is not such
a multiple) the yields of the relevant Treasury Constant Maturity Yield Indices
(rounded, if necessary, to the nearest 1/100 of 1% with any figure of 1/200 of
1% or above rounded upward). In the event that any Yield Maintenance Premium is
due hereunder, Holder shall deliver to Maker a statement setting forth the
amount and determination of the Yield Maintenance Premium and, provided that
Holder shall have in good faith applied the formula described above, Maker shall
not have the right to challenge the calculation or the method of calculation set
forth in any such statement in the absence of manifest error, which calculation
may be made by Holder on any day during the thirty (30) day period preceding the
date of such prepayment. Holder shall not be obligated or required to have
actually reinvested the prepaid principal balance at the Treasury Constant
Maturity Yield Index or otherwise as a condition to receiving the Yield
Maintenance Premium. No Yield Maintenance Premium or premium shall be due or
payable in connection with any prepayment of the indebtedness evidenced by this
Note made on or after any date after July 1, 2006. In addition to the aforesaid
Yield Maintenance Premium if, upon any such prepayment (whether prior to or
after any date that is after July 1, 2006, the aforesaid prior written notice
has not been received by Holder, the Yield Maintenance Premium shall be
increased by an amount equal to the lesser of (i) thirty (30) days' unearned
interest computed in the outstanding principal balance of this Note, so prepaid
and (ii) unearned interest computed on the outstanding principal balance of this
Note so prepaid for the period from, and including, the date of prepayment
through the otherwise Stated Maturity Date of this Note.

      Without limiting the scope of the foregoing provisions, the provisions of
this paragraph shall constitute, within the meaning of any applicable state
statute, both a waiver of any right Maker may have to prepay the Note, in whole
or in part, without premium or charge, upon acceleration of the maturity of the
Note, or otherwise, and an agreement by Maker to pay the prepayment charge
described in this Note, whether such prepayment is voluntary or upon or
following any acceleration of this Note, or otherwise, and for such purpose
Maker has separately initialed this provision in the space provided below, and
Maker hereby declares that Holder's agreement to make the Loan to Maker at the
interest rate and for the term set forth in the Note constitutes adequate
consideration, of individual weight, for this waiver and agreement by Maker.


                                Maker's Initials:


                                       13
<PAGE>

      5. Representations and Warranties of Maker. Maker represents and warrants

      Project and enter into the Debt Papers and consummate the transactions
      contemplated thereby;

            (b) No Violation. Maker's execution, delivery and performance of its
      obligations under the Debt Papers do not and will not violate the articles
      of incorporation or by-laws of Maker and will not violate, conflict with
      or constitute a default under any agreement to which Maker is a party or
      by which the Project is bound or encumbered, or violate any Requirements
      of Law to which Maker or the Project is subject;

            (c) Consents. No consents, approvals, filings, or notices of, with
      or to any Person are required on the part of Maker in connection with
      Maker's execution, delivery and performance of its obligations under the

      may be;

            (d) Enforceability. The Debt Papers are valid, binding and
      enforceable in accordance with their terms, except as the enforceability
      thereof may be limited by bankruptcy, insolvency, moratorium,
      reorganization or similar laws relating to or affecting the enforcement of
      creditors' rights generally.

            (e) Compliance with Laws. Each Mortgaged Property is in compliance
      in all material respects with all applicable Requirements of Law;

            (f) Zoning and Other Laws. The Project and the use thereof as a
      self-storage facility, separate and apart from any other properties,
      constitutes a legal and conforming use under applicable zoning regulations
      and each such Project is in compliance in all material respects with all
      applicable Requirements of Law;

            (g) Litigation. No litigation, investigation or proceeding or notice
      thereof before any arbitrator or governmental authority, agency or

      presently proposed to be conducted, or which are required by any
      governmental entity or agency;

            (i) Easements. Maker has obtained and has encumbered in favor of
      Holder pursuant to the Mortgage all easements, appurtenances and rights of
      way necessary for access to and the normal uses of the Project; and

            (j) Place of Business. Maker is located at 715 South Country Club
      Drive, Mesa, AZ 85210, and that address is its only place of business or
      its chief executive office.

      6. Affirmative Covenants. Maker hereby covenants and agrees that, so long
as any indebtedness under the Note remains unpaid, Maker shall:

            (a) Use of Proceeds. Use the proceeds of the Loan to repay certain
      indebtedness presently outstanding against the Project and held by Payee.

            (b) Financial Statements. Deliver or cause to be delivered to
      Holder, the Trustee and the Servicer:

      period commencing at the end of the previous fiscal year and ending with
      the end of such quarter, and (2) financial reports on the Project showing
      all income and expenses, certified to be accurate and complete by an
      officer of the managing general partner of Maker (or, if Maker is a
      corporation, of Maker); and

                  (iii) Promptly, such additional financial and other
      information (including, without limitation, information regarding the
      Project) as Holder, the Trustee or the Servicer may from time to time
      reasonably request.

            (c) Inspection of Property: Books and Records: Discussions. Keep
      proper books of record and account in which full, true and correct entries
      in conformity with GAAP and all Requirements of Law shall be made of all
      dealings and transactions in relation to its business and activities and,
      upon reasonable notice, permit representatives of Holder, the Trustee, and
      the Servicer to examine and make abstracts from any of its books and
      records at any reasonable time and as often as may reasonably be desired
      by Holder, the Trustee or the Servicer and to discuss the business,
      operations, properties and financial and other conditions of Maker with
      officers and employees of Maker and with its independent certified public
      accountants. In addition, on the last day of each calendar month on which
      an Interest payment is due, Maker shall furnish to Holder a certified
      statement of operations of the Project for the calendar month in which
      such Interest payment is due, showing in reasonable detail and in a format
      approved by Holder the Gross Receipts, Operating Expenses, and Net Cash
      Flow, as well as (if required by Holder) all data necessary for the
      calculation of any such amounts. Maker shall keep and maintain at all
      times full and accurate books of account and records adequate to correctly
      reflect all such amounts. Such books and records shall be available for at
      least five (5) years after the end of the relevant calendar month. Holder
      shall have the right to inspect, copy and audit such books of account and
      records at Holder's expense, during reasonable


                                       15
<PAGE>
      business hours, and upon reasonable notice to Maker, for the purpose of
      verifying the accuracy of any principal payments made. The costs of any
      such audit will be paid by Holder, except that Maker shall pay all
      reasonable costs and expenses of any such audit which discloses that any
      amount properly payable by Maker to Holder hereunder exceeded by five
      percent (5%) or more the amount actually paid and initially reported by
      Maker as being payable with respect thereto.

            (d) Notices. Give prompt written notice to Holder, the Trustee and
      the Servicer of (a) any claims, proceedings or disputes (whether or not
      purportedly on behalf of Maker) against, or to Maker's knowledge,
      threatened or affecting Maker or the Project which, if adversely
      determined, could reasonably be expected to have a Material Adverse Effect
      (without in any way limiting the foregoing, claims, proceedings, or
      disputes involving in the aggregate monetary amounts in excess of $15,000
      not fully covered by insurance shall be deemed to be material, exclusive
      of deductibles in an amount not to exceed $1,000), or (b) any proposal by
      any public authority to acquire the Project or any portion thereof.

            (e) Expenses. Pay all reasonable out-of-pocket expenses (including
      fees and disbursements of counsel, including special local counsel) of
      Holder, incident to any amendments, waivers and renewals relating to the
      Debt Papers and the protection of the rights of Holder under the Debt
      Papers whether by judicial proceedings or otherwise, including, without
      limitation, in connection with bankruptcy, insolvency, liquidation,
      reorganization, moratorium or other similar proceedings involving Maker or
      a "workout" of the Loan. The obligations of Maker under this Section 6(e)
      shall survive repayment of the Loan.

            (f) Debt Papers. Comply with and observe all terms and conditions of
      the Debt Papers.

            (g) INDEMNIFICATION. INDEMNIFY AND HOLD HARMLESS HOLDER AND ITS
      DIRECTORS, OFFICERS, EMPLOYEES, ATTORNEYS AND AGENTS (THE "INDEMNIFIED
      PARTIES") FROM AND AGAINST ALL DAMAGES AND LIABILITIES (COLLECTIVELY AND
      SEVERALLY, "LOSSES") ASSESSED AGAINST ANY OF THEM RESULTING FROM THE
      CLAIMS OF ANY PARTY RELATING TO OR ARISING OUT OF THE DEBT PAPERS OR THE
      TRANSACTIONS CONTEMPLATED THEREBY, EXCEPT FOR LOSSES CAUSED BY THE GROSS
      NEGLIGENCE OR WILLFUL MISCONDUCT OF SUCH INDEMNIFIED PARTY, AND REIMBURSE
      EACH INDEMNIFIED PARTY FOR ANY EXPENSES (INCLUDING THE FEES AND
      DISBURSEMENTS OF LEGAL COUNSEL) REASONABLY INCURRED IN CONNECTION WITH THE
      INVESTIGATION OF, PREPARATION FOR OR DEFENSE OF ANY ACTUAL OR THREATENED
      CLAIM, ACTION OR PROCEEDING ARISING THEREFROM (INCLUDING ANY SUCH COSTS OF
      RESPONDING TO DISCOVERY REQUEST OR SUBPOENAS), REGARDLESS OF WHETHER
      HOLDER OR SUCH OTHER INDEMNIFIED PERSON IS A PARTY THERETO. WITHOUT
      DEROGATING THE PROVISIONS OF SECTION 20 BELOW, IT IS ACKNOWLEDGED AND
      AGREED BY MAKER


                                       16
<PAGE>
      THAT THE INDEMNIFICATION RIGHTS OF THE INDEMNIFIED PARTIES HEREUNDER ARE
      IN ADDITION TO AND CUMULATIVE WITH ALL OTHER RIGHTS OF THE INDEMNIFIED
      PARTIES. WITH REFERENCE TO THE PROVISIONS SET FORTH ABOVE IN THIS SECTION
      6(G) FOR PAYMENT BY MAKER OF ATTORNEYS' FEES INCURRED BY THE INDEMNIFIED
      PARTIES IN ANY ACTION OR CLAIM BROUGHT BY A THIRD PARTY, MAKER SHALL, IF
      IT ADMITS LIABILITY HEREUNDER TO ANY INDEMNIFIED PARTY, DILIGENTLY DEFEND
      SUCH INDEMNIFIED PARTY AND DILIGENTLY CONDUCT THE DEFENSE. IF HOLDER OR
      ANY OTHER SUCH INDEMNIFIED PARTY DESIRES TO ENGAGE SEPARATE COUNSEL, IT
      MAY DO SO AT ITS OWN EXPENSE; PROVIDED, HOWEVER, THAT SUCH LIMITATION ON
      THE OBLIGATION OF MAKER TO PAY THE FEES OF SEPARATE COUNSEL FOR SUCH
      INDEMNIFIED PARTY SHALL NOT APPLY IF SUCH INDEMNIFIED PARTY HAS RETAINED
      SAID SEPARATE COUNSEL BECAUSE OF A REASONABLE BELIEF THAT MAKER IS NOT
      DILIGENTLY DEFENDING IT AND/OR NOT DILIGENTLY CONDUCTING THE DEFENSE AND
      SO NOTIFIES MAKER. THE OBLIGATIONS OF MAKER UNDER THIS SECTION 6(G) SHALL
      SURVIVE REPAYMENT IN FULL OF THE INDEBTEDNESS EVIDENCED HEREBY. EXCEPT AS
      OTHERWISE PROVIDED, IT IS THE INTENT OF THIS SECTION 6(G) THAT THE MAKER
      SHALL INDEMNIFY AND HOLD HARMLESS THE INDEMNIFIED PARTIES FROM LOSSES
      OCCASIONED BY THE ACTS OR OMISSIONS, INCLUDING, WITHOUT LIMITATION,
      NEGLIGENCE, OF THE INDEMNIFIED PARTIES.

      Project Manager shall be employed pursuant to an agreement (the "Property
      Management Agreement") approved by the Holder. In no event shall the fees

      (6%) of Gross Receipts for any time period. The Maker agrees, upon request
      of the Holder, to exercise its right to terminate any Project Manager upon
      the occurrence and continuance of (i) an Event of Default, (ii) a Sale of
      U-Haul International, Inc. or such Project Manager, (iii) a breach by such

action or decision by Holder); and the Holder shall have and may exercise any
and all rights and remedies available at law or in equity and also any and all
rights and remedies provided in the Mortgage and any of the other Security

      12. Waiver.

            (a) Maker, for itself and for its successors, transferees and
      assigns and all guarantors and endorsers, hereby waives diligence,
      presentment and demand for payment, protest, notice of protest and
      nonpayment, dishonor and notice of dishonor, notice of the intention to
      accelerate, notice of acceleration, and all other demands or notices of
      any and every kind whatsoever (except only for any notice of default
      expressly provided for in Section 8 of this Note or in the Security
      Documents) and the undersigned agrees that this Note and any or all
      payments coming due hereunder may be extended from time to time in the
      sole discretion of the Holder hereof without in any way affecting or
      diminishing their liability hereunder.

            (b) No extension of the lime for the payment of this Note or any
      payment becoming due or payable hereunder, which may be made by agreement
      with any Person now or hereafter liable for the payment of this Note,
      shall operate to release, discharge, modify, change or affect the original
      liability under this Note, either in whole or in part, of the Maker if it
      is not a party to such agreement.

            (c) No delay in the exercise of any right or remedy hereunder shall
      be deemed a waiver of such right or remedy, nor shall the exercise of any
      right or remedy be deemed an election of remedies or a waiver of any other
      right or remedy. Without limiting the generality of the foregoing, the
      failure of the Holder hereof promptly after the occurrence of any Event of
      Default hereunder to exercise its right to declare the indebtedness
      remaining unmatured hereunder to be immediately due and payable shall not
      constitute a waiver of such right while such Event of Default continues
      nor a waiver of such right in connection with any future Event of Default
      on the part of the undersigned.

      13. Payment of Costs. The undersigned hereby expressly agrees that upon
the occurrence of any Event of Default under this Note, the undersigned will pay
to the Holder hereof, on demand, all costs of collection or enforcement of every
kind, including (but not limited to) all attorneys' fees, court costs, and other
costs and expenses of every kind incurred by the Holder hereof, on demand, all
costs of collection or enforcement of every kind, including (but not limited to)
all attorneys' fees, court costs, and other costs and expenses of every kind
incurred by the Holder hereof in connection with the protection or realization
of any or all of the security for this Note, whether or not any lawsuit is ever
filed with respect thereto.

      14. The Debt Papers. This Note is unsecured. The Senior Loan is secured
by, inter alia, (i) certain Deeds of Trust (and Mortgages, and Deeds to Secure
Debt), Assignment of Leases and Rents, Security Agreement and Financing
Statement, made and granted by Maker to or for the benefit of Senior Holder,
which creates a lien on real estate in the Project and which also creates a
security interest in personal property located thereat or utilized in connection
therewith; (ii) the Assignment and Pledge Agreement; and (iii) the Collection
Account Agreement (such documents together with each and every additional
document or instrument which may at any time be delivered to the Senior Holder

herein as the "Security Documents"). Reference should be made to the Mortgage
