      indebtedness evidenced by this Note is secured pursuant to that certain mortgage
      loan assignment agreement of even date herewith (the "Mortgage
      Loan Assignment Agreement"),
      assigning the mortgage loans more particularly described therein as well as
      Borrower's interest in the real property securing such Mortgage Loans

      as

    Section 3.  Prepayment.  The
      Original Principal Amount of this Note is not subject to optional prepayment
      but
      is subject to mandatory prepayment prior to the Maturity Date upon the terms
      and
      conditions specified in the Loan Agreement.

     

    Section 4.  Default
      and Acceleration.  If
      an Event of Default (as defined in the Loan Agreement), other than an Event
      of
      Default described in Section 6.1(g)
      of the
      Loan Agreement has occurred and is continuing, Lender may at any time, in
      addition to any other rights or remedies available to it pursuant to this Note,
      the Loan Agreement and the Mortgage Loan Assignment Agreement, or at law or
      in
      equity, take such action, without notice or demand, that Lender deems advisable
      to protect and enforce its rights against Borrower and in any of the Collateral
      (as defined in the Loan Agreement), including, without limitation, by notice
      to
      Borrower, declare the Debt to be forthwith due and payable, whereupon such
      Debt
      shall become and be forthwith due and payable, without presentment, demand,
      protest or further notice of any kind, all of which are hereby expressly waived
      by Borrower, and may enforce or avail itself of any or all rights or remedies
      provided in this Note, the Loan Agreement and the Mortgage Loan Assignment
      Agreement against Borrower and/or the Collateral (including selling the Mortgage
      Loans); and upon an Event of Default described in Section 6.1(g)
      of the
      Loan Agreement, the Debt shall automatically become and be due and payable,
      without presentment, demand, protest or any notice of any kind, all of which
      are
      hereby expressly waived by Borrower. "Debt"
      means
      (a) the outstanding principal balance of this Note, (b) interest,
      default interest at the Default Rate, late charges and other sums, as provided
      in this Note, the Loan Agreement or the Mortgage Loan Assignment Agreement,
      (c) all other monies agreed or provided to be paid by Borrower in this
      Note, the Loan Agreement or the Mortgage Loan Assignment Agreement, and

      of or substitution of the Debt or any part thereof, or the acquisition or
      perfection of the security therefor, whether made or incurred at the request
      of
      Borrower or Lender.

     

    Section 5.  Savings
      Clause.  It
      is expressly stipulated and agreed to be the intent of Borrower and Lender
      that
      this Note complies with the applicable usury and other laws relating to this
      Note now or hereafter in effect. If any such applicable laws render usurious
      any
      amount called for under this Note, or contracted for, charged or received with
      respect to this Note, or if the acceleration of the maturity of this Note or
      if
      any prepayment by Borrower results in Borrower having paid any interest in
      excess of that permitted by applicable law, then it is the express intent of
      the
      parties that all excess amounts theretofore collected by Lender be refunded
      to
      Borrower, and the provisions of this Note immediately be deemed reformed and
      the
      amounts thereafter collected under this Note reduced, without the necessity
      of
      the execution of any new document, so as to comply with the then applicable
      law,
      but so as to permit the recovery of the fullest amount otherwise called for
      under this Note.

     

    Section 6.  Late
      Charges; Mortgage Default Interest Rate.

     

    (a)  Subject
      to Section 5,
      in the
      event that any installment of interest or principal shall become overdue for
      a
      period in excess of five (5) days, a "late charge" in an amount equal to
      five percent (5%) of the amount so overdue may be charged to Borrower by Lender
      for the purpose of defraying the expenses incident to handling such delinquent
      payments. Subject to Section 5,
      such
      late charge shall be in addition to, and not in lieu of, any other remedy Lender
      may have and is in addition to Lender's right to collect reasonable fees and
      charges of any agents or attorneys which Lender may employ in connection with
      any default.

    (b)  If
      Borrower shall default in any payment of principal or interest, or any other
      amount owed by Borrower under this Note, the Loan Agreement or the Mortgage
      Loan
      Assignment Agreement, Borrower shall pay interest on the unpaid principal amount
      of this Note, payable in arrears on each Interest Payment Date and on demand,
      at
      a rate per annum equal at all times to the lesser of (x) the maximum
      non-usurious rate permitted by applicable law or (y)  three percent (3%)
      per annum above the applicable Interest Rate until such defaulted amount has
      been paid by Borrower, together with interest thereon at the Default Rate.
      Payment or acceptance of the increased rate as provided in this Section is
      not a
      permitted alternative for timely payment and shall not constitute a waiver
      of a
      Default or an Event of Default or an amendment to this Note, the Loan Agreement
      or the Mortgage Loan Assignment Agreement and shall not otherwise prejudice
      or
      limit any rights or remedies of Lender.

     

    Section 7.  No
      Oral Change.  This
      Note may not be modified, amended, waived, extended, changed, discharged or
      terminated orally or by act or failure to act on the part of Borrower or Lender,
      but only by an agreement in writing signed by the party against whom enforcement
      of any modification, amendment, waiver, extension, change, discharge or
      termination is sought.

     

    Section 8.  Waivers.  Except
      for any notices expressly provided for in this Note, the Loan Agreement or
      the
      Mortgage Loan Assignment Agreement, Borrower and all others who may become
      liable for the payment of all or any part of the Debt do hereby severally waive
      presentment and demand for payment, notice of dishonor, protest and notice
      of
      protest and non-payment and all other notices of any kind. No release of any
      security for the Debt or extension of time for payment of this Note or any
      installment hereof, and no alteration, amendment or waiver of any provision
      of
      this Note, the Loan Agreement or the Mortgage Loan Assignment Agreement between
      Lender or any other person or party shall release, modify, amend, waive, extend,
      change, discharge, terminate or affect the liability of Borrower, and any other
      person or entity who may become liable for the payment of all or any part of
      the
      Debt, under this Note, the Loan Agreement or the Mortgage Loan Assignment
      Agreement. No notice to or demand on Borrower shall be deemed to be a waiver
      of
      the obligation of Borrower or of the right of Lender to take further action
      without further notice or demand as provided for in this Note, the Loan
      Agreement or the Mortgage Loan Assignment Agreement. Any failure of Lender
      to
      insist upon strict performance by Borrower of any of the provisions of this
      Note, the Loan Agreement or the Mortgage Loan Assignment Agreement shall not
      be
      deemed a waiver of any of the terms or provisions of this Note, the Loan
      Agreement or the Mortgage Loan Assignment Agreement, and Lender shall have
      the
      right thereafter to insist upon strict performance by Borrower of any and all
      of
      them.

     

    Section 9.  Non
      Recourse.  Except
      as otherwise provided herein and the Loan Agreement and the Mortgage Loan
      Assignment Agreement, Lender shall not enforce the liability and obligation
      of
      Borrower to perform and observe the obligations contained in this Note, the
      Loan
      Agreement and the Mortgage Loan Assignment Agreement by any action or proceeding
      wherein a money judgment shall be sought against Borrower, except that Lender
      may bring an action or proceeding to enable Lender to enforce and realize upon
      this Note, the Loan Agreement and the Mortgage Loan Assignment Agreement, and
      the interest in the Mortgage Loans and in any Collateral (as defined in the
      Loan
      Agreement) given to Lender created by this Note, the Loan Agreement or the
      Mortgage Loan Assignment Agreement, provided, however, that any judgment in
      any
      action or proceeding shall be enforceable against Borrower only to the extent
      of
      Borrower's interest in the Mortgage Loans and other Collateral given to Lender.
      The provisions of this Section shall not however (i) constitute a waiver,
      release or impairment of any obligation evidenced or secured by this Note,
      the
      Loan Agreement or the Mortgage Loan Assignment Agreement, (ii) affect the
      validity or enforceability of any indemnity made in connection with this Note,
      the Loan Agreement or the Mortgage Loan Assignment Agreement, or
      (iii) impair the enforcement of the Mortgage Loan Assignment
      Agreement.
