            or oral)  received from the other party shall be deemed to be an assurance or guarantee as to the
            expected results of the Transaction.  Notwithstanding the foregoing,  in the case of the Trustee,
            it has been directed by the Pooling and Servicing Agreement to enter into this Transaction.

(b)         ASSESSMENT AND UNDERSTANDING.  It is capable of assessing the merits of and understanding (on its
            own behalf or through independent  professional  advice), and understands and accepts, the terms,
            conditions and risks of the Transaction.  It is also capable of assuming,  and assumes, the risks
            of the Transaction.

(c)         STATUS OF  PARTIES.  The other  party is not  acting as a  fiduciary  for or an  adviser to it in
            respect of the Transaction,  and in the case of the Supplemental  Interest Trust Trustee,  it has
            been directed by the Pooling and Servicing Agreement to enter into this Transaction.

(d)         PURPOSE.  It is  entering  into the  Transaction  for the  purposes  of  hedging  its  assets  or

Accordingly, the parties agree as follows:--

1.       INTERPRETATION

(A)      DEFINITIONS.  The terms  defined  in Section 14 and in the  Schedule  will have  the meanings therein
specified for the purpose of this Master Agreement.

(b)      INCONSISTENCY.  In the event of any  inconsistency  between the  provisions  of  the Schedule and the

                  A, (c) only Party A makes the pledge and grant in Paragraph 2, the  acknowledgement in the

                  Subject to New York Law version) as published and copyrighted by the  International  Swaps
                  and Derivatives Association, Inc.

(v)      EXPOSURE.  The Parties  agree that in the event of a Ratings  Event  relating to an action taken by
                  S&P, the Valuation  Agent shall  internally  verify its calculation of the Secured Party's
                  Exposure by reporting its calculation  thereof to S&P on a weekly basis.  In addition,  in
                  the case  where the long term  unubordinated  and  unsecured  debt of Party A ceases  tobe
                  rated at least BBB+ by S&P, the Valuation  Agent shall  externally  verify its calculation
                  of the Secured Party's Exposure by seeking two quotations from Reference  Market-makers at
                  the end of each month (such  quotations  being for  amounts  payable as  described  in the
                  definition  of  "Market  Quotations"  in the  Agreement  where  the  date  on  which  such
                  quotations  are sought is the Early  Termination  Date and the  Transaction  entered  into
                  pursuant  to the  Agreement  is the  only  Termination  Transaction).  In the  case  where
                  external  verification of the Exposure  calculation is required,  the Valuation Agent must
                  (i) obtain at least two such  quotations  (ii) may not obtain the  quotations  referred to
                  above from the same  Reference  Market-maker  in excess of four times  during any 12 month
                  period.  Furthermore,  the Exposure  valuations should reflect the higher of two bids from
                  Reference  Market-makers  that  would be  eligible  and  willing  to  provide  the  market

                  Collateral  that has been posted to the Secured  Party,  the Pledgor shall post the amount
                  of Eligible  Collateral  necessary  to cure such  deficiency  to the Secured  Party within
