4.      INTEREST; PAYMENTS.

        4.1     DEFINITIONS. The following terms shall have the meanings

                "ACTUAL/360 BASIS" shall mean on the basis of a 360-day year and
                charged on the basis of actual days elapsed for any whole or

                "30/360 BASIS" shall mean on the basis of a 360-day year
                consisting of 12 months of 30 days each.

                "INTEREST RATE" shall mean a fixed annual rate of 6.20%.

        4.2     INTEREST ACCRUAL. Interest on the outstanding principal balance
                of this Note shall accrue from the Disbursement Date at an
                annual rate equal to the Interest Rate calculated on an
                Actual/360 Basis.

        4.3     PAYMENTS. Monthly payments hereunder shall commence on the first
                day of the calendar month following the Disbursement Date and
                continue on the first day of each calendar month thereafter
                through the Maturity Date. If the Disbursement Date is a date
                other than the first day of a calendar month, the first monthly
                payment shall be interest only. Subsequent monthly payments
                shall be calculated on the basis of an equal-payment twenty-five
                (25) year amortization of principal and interest.
                Notwithstanding that interest on this Note accrues on an
                Actual/360 Basis, the total amount of each such amortized
                monthly payment of principal and Interest shall be determined
                using a 30/360 Basis. On the Maturity Date, all unpaid principal
                and accrued but unpaid interest shall be due and owing in full.
                All interest shall be paid in arrears. Except as otherwise
                specifically provided in this Note or the other Loan Documents,
                all payments and deposits due under this Note or the other Loan

                                        2
<Page>

                Documents shall be made to Lender not later than 12:00 noon,
                California time, on the day on which such payment or deposit is
                due. Any funds received by Lender after such time shall, for all
                purposes, be deemed to have been received on the next succeeding
                Business Day.

        4.4     ACKNOWLEDGMENTS. Borrower acknowledges that interest calculated
                on an Actual/360 Basis exceeds interest calculated on a 30/360
                Basis and, therefore; (a) a greater portion of each monthly
                installment of principal and interest will be applied to
                interest using the Actual/360 Basis than would be the case if
                interest accrued on a 30/360 Basis; and (b) the unpaid
                principal balance of this Note on the Maturity Date will be
                greater using the Actual/360 Basis than would be the case if
                interest accrued on a 30/360 Basis.

        4.5     APPLICATION OF PAYMENTS. In the absence of a specific
                determination by Lender to the contrary, all payments paid by
                Borrower to Lender in connection with the obligations of
                Borrower under this Note and under the other Loan Documents
                shall be applied in the following order of priority: (a) to
                amounts, other than principal and interest due to Lender
                pursuant to this Note or the other Loan Documents; (b) to
                accrued but unpaid interest on this Note; and (c) to the unpaid
                principal balance of this Note. Borrower irrevocably waives the
                right to direct the application of any and all payments at any
                time hereafter received by Lender from or on behalf of Borrower,
                and Borrower irrevocably agrees that Lender shall have the
                continuing exclusive right to apply any and all such payments
                against the then due and owing obligations of Borrower in such
                order of priority as Lender may deem advisable.

5.      LATE CHARGE; DEFAULT RATE.

        5.1     LATE CHARGE. If all or any portion of any payment or deposit
                required hereunder (other than the payment due on the Maturity
                Date) is not paid or deposited on or before the fourth day
                following the day on which such payment or deposit is due,
                Borrower shall pay a late or collection charge, as liquidated
                damages, equal to 5% of the amount of such unpaid payment or
                deposit. If all or any portion of the payment due on the
                Maturity Date is paid more than 4 days after the Maturity Date
                and on a date other than the first day of a month. Borrower
                shall pay a late or collection charge, as liquidated damages,
                equal to the interest which would have accrued on such amount
                during the period commencing on the date payment of such amount
                is actually made and ending on the last day of the month in
                which payment of such amount is actually made. Borrower
                acknowledges that Lender will incur additional expenses as a
                result of any late payments or deposits hereunder, which
                expenses would be impracticable to quantify, and that Borrower's
                payments under this Section 5.1 are a reasonable estimate of
                such expenses.

        5.2     DEFAULT RATE. Commencing upon a Default and continuing until
                such Default shall have been cured by Borrower, all sums owing
                on this Note shall bear interest until paid in full at an annual
                rate equal to 5% plus the Interest Rate, but not higher than the
                maximum rate of interest permitted by applicable law ("Default
                Rate").

6.      MAXIMUM RATE PERMITTED BY LAW. Neither this Note nor any of the other
        Loan Documents shall require the payment or permit the collection of any
        Interest or any late payment charge in excess of the maximum rate
        permitted by law. If any such excess interest or late payment charge is
        provided for under this Note or any of the other Loan Documents or if
        this Note or any of the other Loan Documents shall be adjudicated to
        provide for such excess, neither Borrower nor Borrower's successors or
        assigns shall be obligated to pay such excess, and the right to demand
        the payment of any such excess shall be and hereby is waived, and this
        provision shall control any other provision of this Note or any of the
        other Loan Documents. If Lender shall collect amounts which are deemed
        to constitute interest and which would increase the effective interest
        rate to a rate in excess of the maximum rate permitted by law, all such
        amounts deemed to constitute interest in excess of the maximum legal
        rate shall, upon such determination, at the option of Lender, be
        returned to Borrower or credited against the outstanding principal
        balance of this Note.

7.      ACCELERATION. If (a) Borrower shall fail to pay when due any sums
        payable under this Note; (b) any other Default shall occur, or (c) any
        other event or condition shall occur which, under the terms of the Deed
        of Trust or any other Loan Document, gives rise to a right of
        acceleration of sums owing under this Note, then Lender, at its sole
        option, shall have the right to declare all sums owing under this Note
        immediately due and payable; provided, however, that if the Deed of
        Trust or any other Loan Document provides for the automatic acceleration
        of payment of sums owing under this Note, all sums owing under this Note
        shall be automatically due and payable in accordance with the terms of
        the Deed of Trust or such other Loan Document.

8.      BORROWER'S LIABILITY.

        8.1     LIMITATION. Except as otherwise provided in this Section 8,

                Loan Documents shall be limited solely to the Property and the
                "Collateral" (as defined in the Deed of Trust).

        8.2     EXCEPTIONS. Nothing contained in Section 8.1 or elsewhere in

                for any losses or damages incurred by Lender (including, without
                limitation, any impairment of Lender's security for the Loan)
                with respect to any of the following matters: (i) fraud or
                willful misrepresentation by Borrower (or any direct or indirect
                owner of Borrower); (ii) material physical waste of the Property
                or the Collateral (provided such waste is not cured within
                thirty (30) days after notice from Lender); (iii) failure to pay
                property or other taxes, assessments or charges (other than
                amounts paid to Lender for taxes, assessments or charges
                pursuant to Impounds as defined in Exhibit A and where Lender
                elects not to apply such funds toward payment of the taxes,
                assessments or charges owed) which may create liens senior to
                the lien of the Deed of Trust on all or any portion of the
                Property; (iv) failure to deliver any insurance or condemnation
                proceeds or awards or any security deposits received by Borrower
                to Lender if such delivery is required pursuant to the terms of
                the Loan Documents or, otherwise to apply such sums as required
                under the terms of the Loan Documents or any other instrument
                now or hereafter securing this Note; (v) failure to apply any
                rents, royalties, accounts, revenues, income, issues, profits
                and other benefits from the Property which are collected or
                received by Borrower during the period of any Default or after
                acceleration of the indebtedness and other sums owing under the
                Loan Documents to the payment of either (i) such indebtedness or
                other sums or (ii) the normal and necessary operating expenses
                of the Property; (vi) any breach by Borrower of any covenant in
                this Note or in the Deed of Trust regarding Hazardous Materials
                (as defined in the Deed of Trust) OR; any representation or
                warranty of Borrower regarding Hazardous Materials proving to
                have been untrue when made; (vii) any representation or warranty
                of Borrower regarding the Ground Lease (as defined in the Deed
                of Trust) proving to have been untrue when made; or (viii) any
                termination, surrender, amendment, restatement, modification, or
                subordination of the Ground Lease having occurred, other than as
                a result of the action or inaction of Lender, without, in each
                case, Lender's prior written consent; or (b) in the event the
                Property or the Collateral shall become an asset in (i) a
                voluntary bankruptcy or insolvency proceeding or (ii) an
                involuntary bankruptcy or insolvency proceeding (other than one
                filed by Lender) which is not dismissed within 120 days of
                filing.

        8.3     NO RELEASE OR IMPAIRMENT. Nothing contained in Section 8.1 shall
                be deemed to release, affect or impair the indebtedness
                evidenced by this Note or the obligations of Borrower under, or
                the liens and security interests created by the Loan Documents,
                or Lender's rights to enforce its remedies under this Note and
                the other Loan Documents, including, without limitation, the
                right to pursue any remedy for injunctive or other equitable

        warranties in favor of Lender contained in Article 5 of the Deed of
        Trust, all covenants contained in Section 6.15 of the Deed of Trust, and

        10.3    DELAY IN ENFORCEMENT. No previous waiver or failure or delay by
                Lender in acting with respect to the terms of this Note or the
                Deed of Trust shall constitute a waiver of any breach, default
                or failure of condition under this Note, the Deed of Trust or
                the obligations secured thereby. A waiver of any term of this
                Note, the Deed of Trust or of any of the obligations secured
                thereby must be made in writing signed by Lender, shall be
                limited to the express terms of such waiver, and shall not
                constitute a waiver of any subsequent obligation of Borrower.
                The acceptance at any time by Lender of any past-due amount
                shall not be deemed to be a waiver of the right to require
                prompt payment when due of any other amounts then or thereafter
                due and payable.

        10.4    TIME OF THE ESSENCE. Time is of the essence with respect to
                every provision hereof.

        10.5    GOVERNING LAW. This Note was accepted by Lender in the state of
                California and the proceeds of this Note were disbursed from the
                state of California, which state the parties agree has a
                substantial relationship to the parties and to the underlying
                transaction embodied hereby. Accordingly, in all respects,
                including, without limiting the generality of the foregoing,
                matters of construction, validity, enforceability and
                performance, this Note, the Deed of Trust and the other Loan
                Documents and the obligations arising hereunder and thereunder
                shall be governed by, and construed in accordance with, the laws
                of the state of California applicable to contracts made and
                performed in such state and any applicable law of the United
                States of America, except that at all times the provisions for
                the enforcement of Lender's STATUTORY POWER OF SALE granted
                under the Deed of Trust securing this Note and the creation,
                perfection and enforcement of the security interests created
                pursuant thereto and pursuant to the other Loan Documents shall
                be governed by and construed according to the law of the state
                where the Property is located. Except as provided in the
                immediately preceding sentence, Borrower hereby unconditionally
                and irrevocably waives, to the fullest extent permitted by law,
                any claim to assert that the law of any jurisdiction other than
                California governs the Deed of Trust, this Note and the other
                Loan Documents.

        10.6    CONSENT TO JURISDICTION. Borrower irrevocably submits to the
                jurisdiction of: (a) any state or federal court sitting in the
                state of California over any suit, action, or proceeding,
                brought by Borrower against Lender, arising out of or relating
                to this Note or the Loan evidenced hereby; (b) any state or
                federal court sitting in the state where the Property is located
                or the state in which Borrower's principal place of business is
                located over any suit, action or proceeding, brought by Lender
                against Borrower, arising out of or relating to this Note or the
                Loan evidenced hereby; and (c) any state court sitting in the
                county of the state where the Property is located over any suit,
                action, or proceeding, brought by Lender to exercise its
                STATUTORY POWER OF SALE under the Deed of Trust or any action
                brought by the Lender to enforce its rights with respect to the
                Collateral. Borrower irrevocably waives, to the fullest extent
                permitted by law, any objection that Borrower may now or
                hereafter have to the laying of venue of any such suit, action,
                or proceeding brought in any such court and any claim that any
                such suit, action, or proceeding brought in any such court has
                been brought in an inconvenient forum.

        10.7    COUNTERPARTS. This Note may be executed in any number of
                counterparts, each of which when executed and delivered shall be
                deemed an original and all of which taken together shall be
                deemed to be one and the same Note.

        10.8    HEIRS, SUCCESSORS AND ASSIGNS. All of the terms, covenants,
                conditions and indemnities contained in this Note and the other
                Loan Documents shall be binding upon the heirs, successors and
                assigns of Borrower and shall inure to the benefit of the
                successors and assigns of Lender. The foregoing sentence shall
                not be construed to permit Borrower to assign the Loan except as
                otherwise permitted in this Note or the other Loan Documents.

        10.9    SEVERABILITY. If any term of this Note, or the application
                thereof to any person or circumstances, shall, to any extent, be
                invalid or unenforceable, the remainder of this Note, or the
                application of such term to persons or circumstances other than
                those as to which it is invalid or unenforceable, shall not be
                affected thereby, and each term of this Note shall be valid and
                enforceable to the fullest extent permitted by law.

        10.10   CONSENTS AND APPROVALS. Wherever Lender's consent, approval,
                acceptance or satisfaction is required under any provision of
                this Note or any of the other Loan Documents, such consent,
                approval, acceptance or satisfaction shall not be unreasonably
                withheld, conditioned or delayed by Lender unless such provision
                expressly so provides.

11.     NOTICES. All notices and other communications that are required or
        permitted to be given to a party under this Note shall be in writing and

        BORROWER:                          LENDER:

        Plaza Santa Fe II LLC              Wells Fargo Bank, N.A.

12.     ADDITIONAL TERMS AND CONDITIONS. The additional terms and conditions set
        forth in EXHIBIT A attached hereto are incorporated herein by this
        reference.

13.     PREPAYMENT - DEFEASANCE ONLY. Borrower acknowledges that any prepayment
        of this Note will cause Lender to lose its interest rate yield on this
        Note and will possibly require that Lender reinvest any such prepayment
        amount in loans of a lesser interest rate yield (including, without
        limitation, in debt obligations other than first mortgage loans on
        commercial properties). As a consequence, Borrower agrees as follows, as
        an integral part of the consideration for Lender's making the Loan:

        13.1    VOLUNTARY PREPAYMENT. Any voluntary prepayment of this Note: (a)
                is prohibited except during the last 6 months of the term, and
                (b) is permitted in full only, and not in part.

        13.2    PREPAYMENT CHARGE.

                a.      BASIC CHARGE. Except as provided below, if this Note is
                        prepaid prior to the last 6 months of the term, whether
                        such prepayment is involuntary or upon acceleration of
                        the principal amount of this Note by Lender following a
                        Default, Borrower shall pay to Lender on the prepayment
                        date (in addition to all other sums then due and owing
                        to Lender under the Loan Documents) a prepayment charge
                        equal to the greater of the following two amounts: (i)
                        an amount equal to 1% of the amount prepaid; or (ii) an
                        amount equal to (a) the amount, if any, by which the sum
                        of the present values as of the prepayment date of all
                        unpaid principal and interest payments required under
                        this Note, calculated by discounting such payments from
                        their respective scheduled payment dates back to the
                        prepayment date at a discount rate equal to the Periodic
                        Treasury Yield (defined below) exceeds the outstanding
                        principal balance of the Loan as of the prepayment date,
                        multiplied by (b) a fraction whose numerator is the
                        amount prepaid and whose denominator is the outstanding
                        principal balance of the Loan as of the prepayment date.
                        For purposes of the foregoing, "Periodic Treasury Yield"
                        means (iii) the annual yield to maturity of the actively
                        traded non-callable United States Treasury fixed
                        interest rate security (other than any such security
                        which can be surrendered at the option of the holder at
                        face value in payment of federal estate tax or which was
                        issued at a substantial discount) that has a maturity
                        closest to (whether before, on or after) the Maturity
                        Date (or if two or more such securities have maturity
                        dates equally close to the Maturity Date, the average
                        annual yield to maturity of all such securities), as
                        reported in The Wall Street Journal or other
                        authoritative publication or news retrieval service on
                        the fifth Business Day preceding the prepayment date,
                        divided by (iv) 12, if scheduled payment dates are
                        monthly, or 4, if scheduled payment dates are quarterly.

                b.      ADDITIONAL CHARGE. If this Note is prepaid on any day
                        other than the first day of a month, whether such
                        prepayment is voluntary, involuntary or upon full
                        acceleration of the principal amount of this Note by
                        Lender following a Default, Borrower shall pay to Lender
                        on the prepayment date (in addition to the basic
                        prepayment charge described in Section 13.2.a above and
                        all other sums then due and owing to Lender under this
                        Note and the other Loan Documents) an additional
                        prepayment charge equal to the interest which would
                        otherwise have accrued on the amount prepaid (had such
                        prepayment not occurred) during the period commencing on
                        the prepayment date and ending on the last day of the
                        month in which the prepayment occurred.

                                        6
<Page>

                c.      EXCLUSION. Notwithstanding the foregoing, no prepayment
                        charge of any kind shall apply in respect to any
                        prepayment resulting from Lender's application of any
                        insurance proceeds or condemnation awards to the
                        outstanding principal balance of the Loan.

        13.3    EFFECT OF PREPAYMENT. No partial prepayment of this Note shall
                change the dates or amounts of subsequent monthly installments
                of principal and interest, unless Lender otherwise agrees in
                writing.

        13.4    WAIVER. Borrower waives any right to prepay this Note except
                under the terms and conditions set forth in this Section 13 and
                agrees that if this Note is prepaid, Borrower shall pay the
                prepayment charge set forth above. Borrower hereby acknowledges
                that: (a) the inclusion of this waiver of prepayment rights and
                agreement to pay the prepayment charge for the right to prepay
                this Note was separately negotiated with Lender; (b) the
                economic value of the various elements of this waiver and
                agreement was discussed; (c) the consideration given by Borrower
                for the Loan was adjusted to reflect the specific waiver and
                agreement negotiated between Borrower and Lender and contained
                herein; and (d) this waiver is intended to comply with
                California Civil Code Section 2954.10.

                accordance with the provisions of this Section 14, at Borrower's
                sole cost and expense.

        14.3    CONDITIONS. Borrower shall only have the right to cause a
                Defeasance if all of the following conditions have been
                satisfied:

                a.      NOTICE. Borrower shall give at least 60 days but not
                        more than 90 days written notice to Lender specifying
                        the Borrower's intended Defeasance Date. Simultaneously
                        with the delivery of such notice, Borrower shall deposit
                        with Lender an amount estimated by Lender to be
                        sufficient to reimburse Lender's anticipated expenses in
                        connection with the Defeasance, for which Borrower shall
                        be solely responsible whether or not the Defeasance
                        shall be completed. If any such notice shall have been
                        given by Borrower, Borrower shall be obligated to
                        complete the Defeasance of the Loan on the Defeasance
                        Date, unless such notice is revoked in writing by
                        Borrower prior to the Defeasance Date. Upon completion
                        of the Defeasance or revocation by Borrower as specified
                        above, Lender shall return any surplus deposit to
                        Borrower;

                b.      NO DEFAULT. No Default shall exist or would exist with
                        notice or passage of time, or both, either on the date
                        of receipt of Borrower's notice under Section 14.3.a

                                Lender, which agreements shall provide, among

                                enforceable against Borrower in accordance with
                                their terms and (c) any REMIC that holds this

                                certifying that in no fiscal year of Successor

                                Defeasance Collateral exceed the interest
                                payable for the same period on the Loan under
                                this Note;

                                withdrawal or qualification of the respective
                                ratings in effect immediately prior to the

                e.      RELEASE OF LIEN. Upon satisfaction of all conditions
                        specified in this Section 14, the Property shall be

                        Successor Borrower shall execute an assumption agreement
                        in form and substance customary in commercial mortgage
                        defeasance transactions, pursuant to which it shall
                        assume Borrower's obligations under this Note and the

                        counsel satisfactory to Lender, and subject only to
                        customary assumptions, qualifications and exceptions,
                        stating, among other things, that such assumption
                        agreement is enforceable against Borrower and Successor
                        Borrower in accordance with its terms and that this Note
                        and the Defeasance Security Agreements, as so assumed,
                        are enforceable against Successor Borrower in accordance
                        with their respective terms, and that the bankruptcy of
                        any affiliate of Successor Borrower will not affect the
                        assets of Successor Borrower; and (y) pay all costs and
                        expenses incurred by Lender or its agents in connection
                        with such assignment and assumption (including, without
                        limitation, the formation or review of Successor
                        Borrower and the preparation of the assumption agreement
                        and related documentation). Upon such assumption by
                        Successor Borrower, Borrower shall be relieved of its
                        obligations under this Note, the Defeasance Security
                        Agreements and the other Loan Documents other than (i)
                        representations and warranties made in connection with
                        the Defeasance, (ii) the obligation to effect the
                        Defeasance in accordance with this Section 14, and to

                        liability for losses to Lender resulting from an
                        avoidance, rescission or set-aside of the Defeasance as
                        a result of actions taken or suffered by Borrower, and
                        (iv) those obligations which are specifically intended
                        to survive the repayment of the Loan or other
                        termination, satisfaction or assignment of this Note,

                        acceptable to Lender (or audited financial statements if
                        Borrower obtains them), showing all assets and
                        liabilities of Borrower;

                d.      ANNUAL BUDGET. Not later than November 15 of each

                        Lender; and

                e.      OTHER INFORMATION. From time to time, upon Lender's
                        delivery to Borrower of at least 10 days' prior written
                        notice, such other information with regard to Borrower,
                        principals of Borrower, guarantors or the Property as
                        Lender may reasonably request in writing.

        2.2     FORM; WARRANTY. Borrower agrees that all financial statements to
                be delivered to Lender pursuant to Section 2.1 shall: (a) be
                complete and correct; (b) present fairly the financial condition
                of the party; (c) disclose all liabilities that are required to
                be reflected or reserved against; and (d) be prepared in
                accordance with the same accounting standard used by Borrower to
                prepare the financial statements delivered to and approved by
                Lender in connection with the making of the Loan or other
                accounting standards acceptable to Lender. Borrower shall be
                deemed to warrant and represent that, as of the date of delivery
                of any such financial statement, there has been no material
                adverse change in financial condition, nor have any assets or
                properties

                                    EXHIBIT A

                been sold, transferred, assigned, mortgaged, pledged or
                encumbered since the date of such financial statement except as
                disclosed by Borrower in a writing delivered to Lender. Borrower
                agrees that all rent rolls and other information to be delivered
                to Lender pursuant to Section 2.1 shall not contain any
                misrepresentation or omission of a material fact.

        2.3     LATE CHARGE. If any financial statement, leasing schedule or
                other item required to be delivered to Lender pursuant to
                Section 2.1(a) through 2.1(d) is not timely delivered following
                Lender's notice, Borrower shall promptly pay to Lender, as a
                late charge, the sum of $500 per item. In addition, Borrower
                shall promptly pay to Lender an additional late charge of $500
                per item for each full month during which such item remains
                undelivered following written notice from Lender. Borrower
                acknowledges that Lender will incur additional expenses as a
                result of any such late deliveries, which expenses would be
                impracticable to quantify, and that Borrower's payments under
                this Section 2.3 are a reasonable estimate of such expenses.

3.      IMPOUNDS.

        3.1     AMOUNTS. Borrower shall deposit with Lender, the amounts
                ("Impounds") stated below on the dates stated below, for the
                purpose of paying the costs stated below:

                a.      TAXES. (i) $23,176 on the Disbursement Date, and (ii) on
                        the first payment date on which both principal and
                        interest under the Loan are payable and on each payment
                        date thereafter, an amount estimated from time to time
                        by Lender in its sole discretion to be sufficient to pay
                        for taxes and other liabilities payable by Borrower
                        under Section 6.9 of the Deed of Trust. The initial
                        estimated monthly amount to be deposited by Borrower on

                b.      INSURANCE. (i) $40,060 on the Disbursement Date, and
                        (ii) on the first payment date on which both principal
                        and interest under the Loan are payable and on each
                        payment date thereafter, an amount estimated from time
                        to time by Lender in its sole discretion to be
                        sufficient to pay for premiums for insurance payable by
                        Borrower under Section 6.10 of the Deed of Trust. The
                        initial estimated monthly amount to be deposited by
                        Borrower on each payment date is $4,006.

                        date on which both principal and interest under the Loan
                        are payable and on each payment date thereafter for
                        tenant improvements, brokerage commissions and other
                        leasing costs that may be required for new tenants in

                        are payable and on each payment date thereafter until
                        such time as the escrow account balance exceeds
                        $750,000 for reimbursement of tenant improvements,
                        brokerage commissions and other leasing costs that may
                        be required for retenanting any space in the Property
                        occupied by an Anchor Tenant (as defined below). At such
                        time as the escrow account balance exceeds $750,000,
                        then, at the time thereafter that all existing Anchor
                        Tenants (or replacement Anchor Tenants acceptable to
                        Lender) are in physical occupancy of their respective
                        space, are open for business, and are paying rent to
                        Borrower pursuant to the terms of their respective
                        leases, Lender shall disburse all funds in the escrow
                        account in excess of $375,000 to Borrower; provided,
                        however, at any time the escrow account balance is less
                        than $375,000, Borrower shall resume making the monthly
                        payment of S12,500 until such time as the escrow account
                        balance exceeds $375,000. For purposes of this Note, an
                        "Anchor Tenant" shall mean any tenant that occupies
                        15,000 or more square feet of the Property.

                e.      DEFERRED MAINTENANCE. $45,000 on the Disbursement Date
                        for Deferred Maintenance Work (defined below).

                        date on which both principal and interest under the Loan
                        are payable and on each payment date thereafter for
                        payment or reimbursement of Capital Expenditures

                all accounts containing Impounds for taxes, insurance, tenant
                improvements, deferred maintenance work and capital expenditures
                shall bear interest at a rate established by Lender or its

                        Borrower or any third party regarding any aspect of any

                following account or such other account as Borrower specifies in
                a notice to Lender:

                              Bank Name:      Banco Popular
                                         -----------------------------------
                        ABA Routing No.:      071924458
                                         -----------------------------------
                           Account Name:      Plaza Santa Fe II LLC
                                         -----------------------------------
                              Reference:      a/c # 0102404100269
                                         -----------------------------------
                                 Advise:
                                         -----------------------------------

                Lender shall determine the funds transfer system and other means
                to be used in making each such release. Borrower agrees that
                each such funds transfer initiated by Lender shall be deemed to
                be a funds transfer properly authorized by Borrower, even if the
                transfer is not actually properly authorized by Borrower.
                Borrower acknowledges that Lender shall rely on the account
                number and ABA routing number set forth above or specified in a
                notice from Borrower to Lender, even if such account number
                identifies an account with a name different from the name so
                specified, or the routing number identifies a bank different
                from the bank so specified. If Borrower learns of any error in
                the transfer of any Impounds or of any transfer which was not
                properly authorized, Borrower shall notify Lender as soon as
                possible in writing but in no case more than 14 days after
                Lender's first confirmation to Borrower of such transfer.

4.      ONE-TIME RIGHT OF TRANSFER OF PROPERTY. Notwithstanding anything to the
        contrary contained in Section 6.15 of the Deed of Trust, Lender shall,
        one time only, consent to the voluntary sale or exchange of all of the
        Property by Trustor (as defined in the Deed of Trust) to a bona-fide
        third party purchaser, without any modification of the terms of this
        Note or the other Loan Documents, if no Default has occurred and is
        continuing and all of the following conditions have been satisfied:

        4.1     Lender's reasonable determination that the proposed purchaser,
                the proposed guarantor, if any, and the Property all satisfy
                Lender's then applicable credit review and underwriting
                standards, taking into consideration, among other things, (a)
                any decrease in the Property's cash flow which would result from
                any increase in real property taxes due to any anticipated
                reassessment of the Property for tax purposes and (b) any
                requirement of Lender that the proposed borrowing entity satisfy
                Lender's then applicable criteria for a single purpose
                bankruptcy remote entity;

        4.2     Lender's reasonable determination that the proposed purchaser
                possesses satisfactory recent experience in the ownership and
                operation of properties comparable to the Property;

        4.3     Intentionally Omitted;

        4.4     the execution and delivery to Lender of such documents and
                instruments as Lender shall reasonably require, in form and
                content reasonably satisfactory to Lender, including, without
                limitation, (i) an assumption agreement under which the
                purchaser assumes all obligations and liabilities of Borrower
                under this Note and the other Loan Documents and agrees to
                periodically pay such new or additional Impounds to Lender as
                Lender may reasonably require, and (ii) a consent to the
                transfer by any existing guarantor and a reaffirmation of such
                guarantor's obligations and liabilities under any guaranty made
                in connection with the Loan or a new guaranty executed by a new
                guarantor reasonably satisfactory to Lender;

        4.5     if required by Lender, delivery to Lender of evidence of title
                insurance reasonably satisfactory to Lender insuring Lender that
                the lien of the Deed of Trust and the priority thereof will not
                be impaired or affected by reason of such transfer or exchange
                of the Property;

        4.6     payment to Lender of an assumption fee equal to 1% of the then
                outstanding principal balance of this Note, but not less than
                $15,000;

        4.7     reimbursement to Lender of any and all costs and expenses paid
                or incurred by Lender in connection with such transfer or
                exchange, including, without limitation, all in-house or outside
                counsel attorneys' fees, title insurance fees, appraisal fees,
                inspection fees, environmental consultant's fees and any fees or
                charges of the applicable rating agencies; and

                                    EXHIBIT A
                                        5

        4.8     if required by Lender, delivery to Lender of written evidence
                from the applicable rating agencies that such transfer or
                exchange will not result in a downgrading, withdrawal or
                qualification of the respective ratings in effect immediately
                prior to the transfer or exchange for any securities issued in
                connection with the securitization of the Loan which are then
                outstanding.

        Lender shall fully release Borrower and any existing guarantor from any
        further obligation or liability to Lender under this Note and the other
        Loan Documents upon the assumption by the purchaser and any new
        guarantor of all such obligations and liabilities and the satisfaction
        of all other conditions precedent to a transfer or exchange in
        accordance with the provisions of this Section.

5.      HOLDBACK. As of the Disbursement Date, Osaka Grill & Seafood ("Osaka"),
        a tenant at the Property, is not open for business and paying rent to
        Borrower pursuant to the terms of that certain lease for a portion of
        the Property between Borrower, as landlord, and Osaka, as tenant (the
        "Osaka Lease"). Accordingly, Borrower hereby acknowledges and agrees
        that Lender, notwithstanding anything to the contrary in this Note or
        the other Loan Documents, shall withhold the sum of Nine Hundred Seventy
        Five Thousand and No/l00ths Dollars ($975,000.00) of the Loan (the
        "Holdback"). The Holdback shall be held in an escrow account by Lender
        or its servicing agent, which may be a commingled account, and shall
        accrue interest at a rate established from time to time by Lender or its
        servicing agent, which may not be the highest rate available (the
        "Holdback Escrow"). The Holdback Escrow shall constitute Collateral (as
        defined in the Deed of Trust). Upon any Default, Lender shall have the
        right, in addition to any other rights of Lender under the Loan
        Documents, to foreclose its security interest in the Holdback Escrow and
        apply the sums to the Holdback Escrow to the repayment of the
        indebtedness outstanding under this Note in such order as Lender shall
        determine. At any time and from time to time, promptly upon Lender's
        request, Borrower shall execute such additional documents and
        instruments as Lender shall reasonably deem necessary or desirable for
        the purpose of confirming and perfecting Lender's security interest in
        the Holdback Escrow. If the Release Conditions (as hereinafter defined)
        are not satisfied to Lender's satisfaction by the date which is six (6)
        months after the Disbursement Date, Borrower agrees (x) that it shall be
        required to pay down the outstanding principal balance of the Loan (out
        of the Holdback Escrow) in an amount equal to the sum necessary to
        provide that the Actual Debt Service Coverage Ratio shall not be less
        than 1.5 to 1.0 and the Adjusted Debt Service Coverage Ratio shall not
        be less than 1.23 to 1.0., and (y) that such payment will be subject to
        the prepayment charge set out in Section 13 of this Note. The Holdback
        (or a portion thereof if a prepayment of the Loan is made pursuant to
        the immediately preceding sentence) shall be released to Borrower upon
        Borrower's satisfaction of the following terms, provisions, and
        conditions precedent (collectively referred to herein as the "Release
        Conditions"): (i) no Default shall have occurred and be continuing; (ii)
        Borrower shall have provided evidence acceptable to Lender that Osaka is
        open for business and paying rent pursuant to the terms of the Osaka
        Lease; (iii) the Actual Debt Service Coverage Ratio shall not be less
        than 1.5 to 1.0; and (iv) the Adjusted Debt Service Coverage Ratio shall
        not be less than 1.23 to 1.0. Notwithstanding anything to the contrary
        contained in this Note, if all the tenants at the Property that have
        entered into leases with Borrower as of the Disbursement Date (other
        than H&R Block) are open for business, paying rent, and have not
        suffered a material adverse change in their financial condition, the Net
        Cash Flow for purposes of calculating the debt service coverage ratios
        in connection with the Release Conditions shall be deemed to be
        $2,211,000.00.

6.      CASH MANAGEMENT. Borrower shall enter into (i) that certain Cash
        Management Agreement of even date herewith among Lender, Borrower, and
        Redford Properties IV, Inc., a Delaware corporation d/b/a CB Richard
        Ellis (the "Cash Management Agreement"), (ii) that certain Restricted
        Account Agreement of even date herewith among Lender, as "Bank", Lender,
        as "Lender", and Borrower (the "Restricted Account Agreement"), and
        (iii) that certain Lockbox Agreement of even date herewith among
        Borrower, Regulus West LLC, and Lender (the "Lockbox Agreement") which
        shall govern the collection and disbursement of Gross Income (as defined
        in the Cash Management Agreement) during the term of the Loan.
