                    2)   the performance of the action (the non-performance of

                         Party B performing the said obligation;

               under the terms of any Transaction Document;

          the Series Trust out of which Party B is actually indemnified for the
          liability. This limitation of Party B's liability applies despite any
          other provision of this Agreement (other than Section 15(c)) and

     (c)  (BREACH OF TRUST): The provisions of this Section 15 will not apply to
          any obligation or liability of Party B to the extent that it is not
          satisfied because under the Master Trust Deed, the Series Supplement
          or any other Transaction Document or by operation of law there is a
          reduction in the extent of Party B's indemnification out of the Assets
          of the Series Trust, as a result of Party B's fraud, negligence or
          wilful default.

     (d)  (ACTS OR OMISSIONS): It is acknowledged that the Relevant Parties are
          responsible under the Transaction Documents for performing a variety

          Party B (including any related failure to satisfy its obligations or
          any breach of a representation or warranty under this Agreement) will
          be considered fraudulent, negligent or a wilful default of Party B for
          the purpose of paragraph (c) of this Section 15 to the extent to which

          liable for in accordance with any Transaction Document) to fulfil its
          obligations relating to the Series Trust or by any other act or
          omission of a Relevant Party or any other such person.

     (e)  (NO AUTHORITY): No attorney, agent, receiver or receiver and manager
          appointed in accordance with any Transaction Document has authority to

          personal liability and no act or omission


                                                                              16



          of any such person will be considered fraud, negligence or wilful
          default of Party B for the purposes of Section 15(c).

     (f)  (NO OBLIGATION): Party B is not obliged to enter into any commitment
          or obligation under this Agreement or any Transaction Document

          accordance with this Section 16 for a maximum term not exceeding 10
          years, Party B and the Manager will be deemed to have satisfied their

          calculation of the Fixed Rate Swap Amount for the purposes of a Fixed
          Rate Swap then existing includes the Amounts Outstanding in relation
          to the Mortgage Loans the subject of the Conversion.

     (b)  If Section 16(a) does not apply and Party B and the Manager enter into
          one or more further Fixed Rate Swaps pursuant to clause 16.6(j) of the
          Series Supplement to hedge the interest rate risk of one or more
          Mortgage Loans the subject of a Conversion, each such further Fixed
          Rate Swap must:

          (i)  (NOTIONAL AMOUNT): have a Notional Amount for each Calculation
               Period at least equal to the aggregate Amounts Outstanding as at

          (iii) (TERMINATION DATE): have a scheduled Termination Date on or
               prior to the tenth anniversary of its Trade Date unless the
               Rating Agencies confirm that entering into the Fixed Rate Swap
               for a longer period will not result in a reduction, qualification
               or withdrawal of the credit ratings then assigned by them to the
               Securities; and

          (iv) (CONFIRMATION): in all other respects be confirmed as a Fixed
               Rate Swap in accordance with this Agreement and the sample

               Agreement.

               ceasing to have a long term credit rating of at least A3 by

               this Agreement in respect of the Fixed Rate Swaps to a
               replacement counterparty acceptable to the Manager and which the
               Rating Agencies confirm in writing will not result in a
               reduction, qualification or withdrawal of the credit ratings then
               assigned by them to the Securities; or

          (v)  enter into such other arrangements in respect of all Fixed Rate
               Swaps which are satisfactory to the Manager and which the Rating
               Agencies confirm in writing will not result in a reduction,
               qualification or withdrawal of the credit ratings then assigned
               by them to the Securities.

     (b)  (FIXED RATE PREPAYMENT AMOUNT): For the purposes of this Section 17

               Securities by Moody's immediately prior to the review of Party
               A's credit rating; and

                    Fixed Rate Swap on the immediately following Distribution
                    Date (calculated on the basis that there will be no
                    prepayments made by the Mortgagors under the Mortgage Loans
                    then being charged interest at a fixed rate and no
                    conversion of the interest rate payable under any Mortgage

                    Period).

               Where:

                                   CR = MM + V


                                                                              19



                    "MM" means the aggregate of the mark-to-market value
                    (whether positive or negative) of all Fixed Rate Swaps
                    determined in accordance with Section 17(c) no earlier than
                    3 Business Days prior to the date that the Fixed Rate
                    Prepayment Amount is lodged.

                    "V" means the volatility buffer, being the value calculated
                    by multiplying the aggregate Notional Amounts (as defined in
                    the relevant Confirmations) of the Fixed Rate Swaps at the
                    most recent Distribution Date by the relevant percentage
                    obtained from the following table:



                    ----------------------------------------------------------------------------
                    COUNTERPARTY   MATURITIES UP TO 5   MATURITIES UP TO 10   MATURITIES GREATER
                    RATING         YEARS                YEARS                 THAN 10 YEARS
                    ----------------------------------------------------------------------------

                    A-2            6.50%                8.25%                 11.75%
                    ---------------
                    A-3            10.00%               14.50%                31.75%
                    ---------------

                    ----------------------------------------------------------------------------


     (c)  (MARK-TO-MARKET VALUE): Party A must calculate the mark-to-market
          value of the Fixed Rate Swaps by obtaining 2 bids from counterparties
          with the Prescribed Ratings willing to provide the Fixed Rate Swaps in
          the absence of Party A. The mark-to-market value may be a positive or
          a negative amount. A bid has a negative value if the payment to be
          made is from the counterparty to Party A and has a positive value if
          the payment to be made is from Party A to the counterparty. The
          mark-to-market value is the higher of the bids (on the basis that any
          bid of a positive value is higher than any bid of a negative value).

     (d)  (RECALCULATION): Party A must recalculate the Fixed Rate Prepayment
          Amount (including the CR and the mark-to-market value) on a weekly
          basis. If:

          (i)  the recalculated Fixed Rate Prepayment Amount is greater than the
               immediately preceding Fixed Rate Prepayment Amount, Party A must
               make an additional prepayment in accordance with Section
               17(a)(iii) within 3 Business Days of such recalculation so that
               the Fixed Rate Prepayment Balance equals the recalculated Fixed
               Rate Prepayment Amount; or

          (ii) the recalculated Fixed Rate Prepayment Amount is less than the
               immediately preceding Fixed Rate Prepayment Amount, Party B must
               upon the direction of the Manager withdraw an amount from the
               Eligible Account referred to in Section 17(a)(iii) and pay it to
               Party A within 3 Business Days of receiving notice of such
               recalculation so that the remaining Fixed Rate Prepayment Balance
               after such withdrawal equals the recalculated Fixed Rate
               Prepayment Amount.

     (e)  (INTEREST): Interest will be payable by Party B on any prepayment by
          Party A under this Section 17 in accordance with clause 8.8 of the
          Series Supplement.

     (f)  (UTILISATION): If the Fixed Rate Prepayment Balance is applied towards
          an amount payable by Party A in accordance with Section 2(f)(i) Party
          A


                                                                              20



          must within 3 Business Days make an additional prepayment in
          accordance with Section 17(a)(iii) equal to the amount so applied.

     (g)  (REPAYMENT): If Party A regains the Prescribed Rating in respect of
          the Fixed Rate Swaps Party B must, upon the direction of the Manager,
          repay to Party A the then Fixed Rate Prepayment Balance.

     (h)  (VARIATION OF MANNER OF SATISFACTION): Notwithstanding that Party A
          has elected to satisfy its obligations pursuant to this Section 17 in
          a particular manner, it may subsequently and from time to time vary
          the manner in which it satisfies its obligations pursuant to this
          Section 17 (but will not be entitled to any additional grace period in
          relation to such a variation).

18.  DOWNGRADING OF PARTY A - BASIS SWAP

     If, as a result of the reduction or withdrawal of its credit rating by a
     Rating Agency, Party A does not have the Prescribed Rating in respect of
     the Basis Swap, Party A must:

     (a)  (30 BUSINESS DAYS): within 30 Business Days of Party A ceasing to have
          the Prescribed Rating if and while Party A has a short term credit
          rating of at least P-1 by Moody's; or

     (b)  (5 BUSINESS DAYS): otherwise, and if sooner, within 5 Business Days of
          Party A ceasing to have a short term credit rating of at least P-1 by
          Moody's;

     (or such greater period as is agreed to in writing by Moody's) (the
     "POSTING PERIOD"), at its cost alone and at its election:

     (c)  (PREPAYMENT):

          (i)  on or before the last day of the Posting Period, pay to Party B
               as a prepayment of its obligations under the Basis Swap for the
               then Calculation Period, the relevant net amount (if any) that is
               expected to be due by Party A to Party B at the end of that
               Calculation Period; and

          (ii) on each Distribution Date which follows such prepayment, pay to
               Party B as a prepayment of its obligations under the Basis Swap
               for the Calculation Period commencing on each such Distribution
               Date, the net amount (if any) that is expected to be due by Party
               A to Party B at the end of that Calculation Period less any Basis
               Swap prepayments relating to any prior Distribution Date held in
               the Basis Prepayment Balance at the end of that Distribution
               Date,

          as determined by the Manager, by depositing such net amount (if any)
          into the Collections Account in cleared funds; or

     (d)  (OTHER ARRANGEMENTS): enter into some other arrangement satisfactory
          to the Manager and Party B which the Rating Agencies confirm will not
          result in a reduction, qualification or withdrawal of the credit
          ratings then assigned by them to the Securities. A prepayment on the
          first day of any Calculation Period by Party A under Section 18(c)
          will constitute a prepayment of Party A's payment obligations (to the
          extent thereof) in


                                                                              21



          respect of the Basis Swap for the Calculation Period commencing on the
          relevant Distribution Date. Notwithstanding that Party A has elected
          to satisfy its obligations pursuant to this Section 18 in a particular
          manner, it may subsequently and from time to time vary the manner in
          which it satisfies its obligations pursuant to this Section 18 (but
          will not be entitled to any additional grace period in relation to
          such a variation). Interest will be payable by Party B on any
          prepayment by Party A under this Section 18 in accordance with clause
          8.8 of the Series Supplement.

19.  SECURITIES REPAID

     On the date that the Invested Amount in respect of the Securities has been
     reduced to zero, or the Securities are redeemed in full or are deemed to
     have been redeemed in full under the Series Supplement, whichever is the
     earlier, Party A's obligations under Sections 17 and 18 will cease and
     Party B must pay to Party A on that date the Outstanding Interest Rate Swap
     Prepayment Amount and interest on such payment.".

(15) TRANSFER:

     Section 7 is replaced with:

     "7.  ESSENTIAL TERM: TRANSFER

     (a)  Neither the interests nor the obligations of either party in or under
          this Agreement (including any Transaction) are capable of being
          assigned or transferred (whether at law, in equity or otherwise),
          charged or the subject of any trust (other than the Series Trust or
          the trusts created pursuant to any Credit Support Document in relation
          to Party B) or other fiduciary obligation. Any action by a party which
          purports to do any of these things is void.

     (b)  Nothing in this Section 7:

          (i)  restricts a transfer by a party after the other party has agreed
               to the variation of this Agreement to the extent necessary to
               permit such transfer;

          (ii) restricts a novation of the interests and obligations of a party
               in or under this Agreement (including any Transaction) including,
               but not limited to, for the purposes of giving effect to a
               transfer under Section 6(b)(ii);

          (iii) restricts a transfer by a party of all or any part of its
               interest in any amount payable to it from a Defaulting Party
               under Section 6(e); or

          (iv) restricts Party B from granting security over a Transaction or
               this Agreement pursuant to any Credit Support Document in
               relation to Party B,

          provided that the Rating Agencies have confirmed that such transfer,
          variation or assignment by way of security (as the case may be) will
          not result in a reduction, qualification or withdrawal of the credit
          ratings then assigned by them to the Securities.

     (c)  Each party acknowledges that the other party enters into this
          Agreement and each Transaction on the basis that this Section 7 must
          be strictly observed and is essential to the terms of this Agreement
          (including each Transaction)."


                                                                              22



(16) KNOWLEDGE OR AWARENESS

     Subject to Section 12(a), each party will only be considered to have
     knowledge or awareness of, or notice of, a thing or grounds to believe
     anything by virtue of the officers of that party or any Related Body
     Corporate of that party which have the day to day responsibility for the
     administration or management of that party's (or a Related Body Corporate
     of that party's) obligations in relation to the Series Trust or the
     Transactions entered into under this Agreement having actual knowledge,
     actual awareness or actual notice of that thing, or grounds or reason to
     believe that thing (and similar references will be interpreted in this
     way).

(17) INTEREST RATE BASIS CAP

     The parties agree that any Interest Rate Basis Cap entered into between
     them pursuant to clause 16.6(k) of the Series Supplement will be entered
     into as a transaction governed by the terms of this Agreement.

(18) AMENDMENT TO THIS AGREEMENT

     The parties to this Agreement may only amend this Agreement in accordance
     with clause 33.1(b) of the Series Supplement.


                                                                              23
