               and conditions of a Transaction will not be considered investment

                         this Schedule; and

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

               Party B is liable for the acts or omissions of such other person
               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

          Trust).

     (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
          the act or omission was caused or contributed to by any Relevant
          Person or any other person appointed by Party B under any Transaction
          Document (other than a person whose acts or omissions Party B is
          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.

                    under 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

                         Outstanding of all Mortgage Loans then being charged
                         interest at a fixed rate; and

                    D.   the net amount (if any) as determined by the Manager
                         that is expected to be due by Party A to Party B in
                         respect of the 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 Loan from a
                         fixed rate to a variable rate or from a variable rate
                         to a fixed rate during the relevant Swap Collection
                         Period).

                    Where:

                                   CR = MM + V

                    "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(d) 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

          (d)  (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).

          (e)  (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) or (b)(i) 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) or (b)(i) 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.

          (f)  (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.

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

          (h)  (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.

          (i)  (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


                                                                              21

          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 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 of the following Distribution Dates, 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 the then 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 respect of the Basis Swap for
          the Calculation Period commencing on that 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.".


                                                                              22

(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).".


                                                                              23

     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.
