partnership, the principal sum of SIXTY MILLION TWO HUNDRED SEVENTY FIVE Dollars
and 00/100 Dollars (US $60,275,000) with interest on each Variable Advance at an

      This Note is executed and delivered by Borrower pursuant to that certain
Amended and Restated Master Credit Facility Agreement, dated as of April 28,
2004, by and between Borrower and ARCS Commercial Mortgage Co., L.P. ("LENDER")
(as amended from time to time, the "MASTER AGREEMENT"), to evidence the
obligation of Borrower to repay Variable Advances made by Lender to Borrower in
accordance with the terms of the Master Agreement. This Note is entitled to the
benefit and security of the Loan Documents provided for in the Master Agreement,
to which reference is hereby made for a statement of all of the terms and
conditions under which the Variable Advances evidenced hereby is made. The
Master Agreement requires certain of the terms of each Variable Advance to be
evidenced by an Advance Confirmation Instrument, and reference is hereby made to
each such Advance Confirmation Instrument for such terms.

      This Note is issued as part of a Variable Facility established in
accordance with the terms of the Master Agreement. Subject to the terms,
conditions and limitations of Article 1 of the Master Agreement, Borrower may
re-borrow any amounts under this Note which they have previously borrowed and
repaid under this Note.

      1.    DEFINED TERMS. As used in this Note, (i) the term "LENDER" means the
holder of this Note, and (ii) the term "INDEBTEDNESS" means the principal of,
interest on, or any other amounts due at any time under, this Note, the Security
Instruments or any other Loan Document, including late charges, default
interest, and advances to protect the security of the Security Instruments under
Section 12 of the Security Instruments. Event of Default and other capitalized
terms used but not defined in this Note shall have the meanings given to such
terms in the Master Agreement or, if not defined in the Master Agreement, as
defined in the Security Instruments (as defined in Paragraph 5).

      2.    ADDRESS FOR PAYMENT. All payments due under this Note shall be
payable at ARCS Commercial Mortgage Co., L.P., 26901 Agoura Road, Suite 200,
Calabasas Hills, California 91301-9932, or such other place as may be designated
by written notice to Borrower from or on behalf of Lender.



      3.    PAYMENT OF PRINCIPAL AND INTEREST. Principal and interest shall be
paid as follows:

      (a)   This Note shall evidence Variable Advances made from time to time
under the Master Agreement. Each Variable Advance shall bear interest at a rate
determined in accordance with Section 2.01 of the Master Agreement.

      (b)   Borrower shall pay imputed interest on each Variable Advance in
advance in the form of a Discount in accordance with Section 1.04(b) of the
Master Agreement (except that Borrower shall pay actual interest on the Variable
Advance for the partial month period, if any, in accordance with Section 1.04(a)
of the Master Agreement). If not sooner paid, the entire principal amount of
each Variable Advance shall be due and payable on the maturity date of the
applicable Variable Advance (the "MATURITY DATE") in accordance with Section
1.03 of the Master Agreement. In addition to payment of principal and the
Discount, Borrower shall pay the Variable Facility Fee due on each Variable
Advance in accordance with Section 1.04(b)(ii) of the Master Agreement. No
Variable Advance may have a Maturity Date later than, and any then outstanding
Variable Advance shall be due and payable in full on, the related Variable
Facility Termination Date.

      4.    APPLICATION OF PAYMENTS. If at any time Lender receives, from
Borrower or otherwise, any amount applicable to the Indebtedness that is less
than all amounts due and payable at such time, Lender may apply that payment to
amounts then due and payable in any manner and in any order determined by
Lender, in Lender's discretion. Borrower agrees that neither Lender's acceptance
of a payment from Borrower in an amount that is less than all amounts then due
and payable nor Lender's application of such payment shall constitute or be
deemed to constitute either a waiver of the unpaid amounts or an accord and
satisfaction.

      5.    SECURITY. The Indebtedness is secured, among other things, by the
Security Instruments described in the Master Agreement and reference is made to
the Security Instruments for other rights of Lender concerning the collateral
for the Indebtedness.

      6.    ACCELERATION. If an Event of Default has occurred and is continuing,
the entire unpaid principal balance, any accrued interest, and all other amounts
payable under this Note and any other Loan Document shall at once become due and
payable, at the option of Lender, without any prior notice to Borrower. Lender
may exercise this option to accelerate regardless of any prior forbearance.

      7.    LATE CHARGE. If any monthly amount payable under this Note or under
the Security Instrument or any other Loan Document is not received by Lender
within 10 days after the amount is due, Borrower shall pay to Lender,
immediately and without demand by Lender, a late charge equal to 5 percent of
such amount. Borrower acknowledges that its failure to make timely payments will
cause Lender to incur additional expenses in servicing and processing the loan
evidenced by this Note (the "LOAN"), and that it is extremely difficult and
impractical to determine those additional expenses. Borrower agrees that the
late charge payable pursuant to this Paragraph represents a fair and reasonable
estimate, taking into account all circumstances existing on the date of this
Note, of the additional expenses Lender will incur by reason of such

                                       -2-


late payment. The late charge is payable in addition to, and not in lieu of, any
interest payable at the Default Rate pursuant to Paragraph 8.

      8.    DEFAULT RATE. So long as any payment due under this Note remains
past due for 30 days or more, interest under this Note shall accrue on the
unpaid principal balance from the due date of such payment, at a rate (the
"DEFAULT RATE") equal to the lesser of 4 percentage points above the rate stated
in the first paragraph of this Note or the maximum interest rate which may be
collected from Borrower under applicable law. If the unpaid principal balance
and all accrued interest are not paid in full on the Maturity Date, the unpaid
principal balance and all accrued interest shall bear interest from the Maturity
Date at the Default Rate. Borrower also acknowledges that its failure to make
timely payments will cause Lender to incur additional expenses in servicing and
processing the Loan, that, during the time that any monthly installment or
payment under this Note is delinquent for more than 30 days, Lender will incur
additional costs and expenses arising from its loss of the use of the money due
and from the adverse impact on Lender's ability to meet its other obligations
and to take advantage of other investment opportunities, and that it is
extremely difficult and impractical to determine those additional costs and
expenses. Borrower also acknowledges that, during the time that any monthly
installment or other payment due under this Note is delinquent for more than 30
days, Lender's risk of nonpayment of this Note will be materially increased and
Lender is entitled to be compensated for such increased risk. Borrower agrees
that the increase in the rate of interest payable under this Note to the Default
Rate represents a fair and reasonable estimate, taking into account all
circumstances existing on the date of this Note, of the additional costs and
expenses Lender will incur by reason of Borrower's delinquent payment and the
additional compensation Lender is entitled to receive for the increased risks of
nonpayment associated with a delinquent loan.

      9.    PERSONAL LIABILITY OF THE BORROWER.

      The provisions of Article 15 of the Master Agreement (entitled "PERSONAL
LIABILITY OF THE BORROWER") concerning the non-recourse nature of the
Indebtedness are hereby incorporated into this Note by this reference to the
fullest extent as if the text of such Article were set forth in its entirety
herein.

      10.   VOLUNTARY AND INVOLUNTARY PREPAYMENTS.

      Pursuant to the terms of the Master Agreement, Borrower shall pay the
entire amount of the Discount on any Variable Advance in advance. Accordingly,
any Variable Advance may be prepaid in whole or in part and at any time without
penalty. Borrower shall give Lender five Business Days advance notice of any
prepayment.

      11.   COSTS AND EXPENSES. Borrower shall pay within 15 days after demand
all expenses and costs, including reasonable fees and out-of-pocket expenses of
attorneys and expert witnesses and costs of investigation, incurred by Lender as
a result of any default under this Note or in connection with efforts to collect
any amount due under this Note, or to enforce the provisions of any of the other
Loan Documents, including those incurred in post-judgment collection efforts and
in any bankruptcy proceeding (including any action for relief from the automatic
stay of any bankruptcy proceeding) or judicial or non-judicial foreclosure
proceeding.

                                       -3-


      12.   FORBEARANCE. Any forbearance by Lender in exercising any right or
remedy under this Note, the Security Instrument, or any other Loan Document or
otherwise afforded by applicable law, shall not be a waiver of or preclude the
exercise of that or any other right or remedy. The acceptance by Lender of any
payment after the due date of such payment, or in an amount which is less than
the required payment, shall not be a waiver of Lender's right to require prompt
payment when due of all other payments or to exercise any right or remedy with
respect to any failure to make prompt payment. Enforcement by Lender of any
security for Borrower's obligations under this Note shall not constitute an
election by Lender of remedies so as to preclude the exercise of any other right
or remedy available to Lender.

      13.   WAIVERS. Except as expressly provided in the Master Agreement,
presentment, demand, notice of dishonor, protest, notice of acceleration, notice
of intent to demand or accelerate payment or maturity, presentment for payment,
notice of nonpayment, grace, and diligence in collecting the Indebtedness are
waived by Borrower and all endorsers and guarantors of this Note and all other
third party obligors.

      14.   LOAN CHARGES. If any applicable law limiting the amount of interest
or other charges permitted to be collected from Borrower in connection with the
Loan is interpreted so that any interest or other charge provided for in any
Loan Document, whether considered separately or together with other charges
provided for in any other Loan Document, violates that law, and Borrower is
entitled to the benefit of that law, that interest or charge is hereby reduced
to the extent necessary to eliminate that violation. Borrower agrees to an
effective rate of interest that is the stated rate of interest plus any
additional rate of interest resulting from any other charges or fees that are to
be paid by Borrower to Lender that may be found by a court of competent
jurisdiction to be interest. The amounts, if any, previously paid to Lender in
excess of the permitted amounts shall be applied by Lender to reduce the unpaid
principal balance of this Note. For the purpose of determining whether any
applicable law limiting the amount of interest or other charges permitted to be
collected from Borrower has been violated, all Indebtedness that constitutes
interest, as well as all other charges made in connection with the Indebtedness
that constitute interest, shall be deemed to be allocated and spread ratably
over the stated term of the Note. Unless otherwise required by applicable law,
such allocation and spreading shall be effected in such a manner that the rate
of interest so computed is uniform throughout the stated term of the Note.

      15.   COMMERCIAL PURPOSE. Borrower represents that the Indebtedness is'
being incurred by Borrower solely for the purpose of carrying on a business or
commercial enterprise, and not for personal, family or household purposes.

      16.   COUNTING OF DAYS. Except where otherwise specifically provided, any
reference in this Note to a period of "days" means calendar days, not Business
Days.

      17.   GOVERNING LAW; CONSENT TO JURISDICTION; WAIVER OF JURY TRIAL. The
provisions of Section 17.06 of the Master Agreement (entitled "Choice of Law;
Consent to Jurisdiction; Waiver of Jury Trial") are hereby incorporated into
this Note by this reference to the fullest extent as if the text of such Section
were set forth in its entirety herein.

                                       -4-


      18.   CAPTIONS. The captions of the paragraphs of this Note are for
convenience only and shall be disregarded in construing this Note.

      19.   NOTICES. All notices, demands and other communications required or
permitted to be given by Lender to Borrower pursuant to this Note shall be given
in accordance with Section 17.08 of the Master Agreement.

      20.   CROSS-DEFAULT WITH MASTER AGREEMENT. The occurrence of an Event of
Default under the Master Agreement shall constitute an "Event of Default" under
this Note, and, accordingly, upon the occurrence of an Event of Default under
the Master Agreement, the entire principal amount outstanding hereunder and
accrued interest thereon shall at once become due and payable, at the option of
the holder hereof.

      21.   ADVANCE CONFIRMATION INSTRUMENTS; ACCOUNTING FOR VARIABLE ADVANCES.
The terms of the Master Agreement and this Note govern the repayment, and all
other terms relating to each Variable Advance. However, Borrower shall execute
an Advance Confirmation Instrument to create a physical instrument evidencing
the Variable Advance. The Advance Confirmation Instrument for a Variable Advance
executed by Borrower in accordance with Section 2.02 of the Master Agreement
shall set forth the amount, term, Discount, Closing Date and certain other terms
of the Variable Advance. The Advance Confirmation Instrument shall conclusively
establish each of the terms described in the preceding sentence, absent manifest
error. The Variable Advance evidenced by the Advance Confirmation Instrument
does not represent a separate indebtedness from that evidenced by this Note. In
making proof of this Note, no other documents other than this Note shall be
required. In making proof of the amount and terms of the outstanding Variable
Advances under this Note, this Note, the Advance Confirmation Instruments for
the Variable Advances, and Lender's records concerning payments made by Borrower
under this Note, shall be conclusive evidence of the terms and outstanding
amounts of each Variable Advance, absent manifest error.

      23.   PRIORITY OF ADVANCES. Each Variable Advance under this Note shall be
evidenced by an Advance Confirmation Instrument, and the lien of each Security
Document executed by Borrower from time to time to secure this Note, shall
secure each separate Advance (and the lien of each Security Instrument and other
Security Document executed by Borrower to secure its obligations under the Loan
Documents) to the same extent and with the same effect as if the Advance had
been made (and any guaranty obligation had been incurred) on the date on which
(i) with respect to each other Security Instrument, the Security Instrument is
recorded in the land records of the jurisdiction in which the real property
covered by the Security Instrument is located, or (ii) with respect to each
other Security Document, the date on which the Security Document is executed and
delivered to Lender.
