                into a Transaction that (absent a written agreement between the
                parties that expressly imposes affirmative obligations to the
                contrary for that Transaction):

                (i)     NON-RELIANCE. It is acting for its own account (in the
                        case of Party B, as trustee of the Series Trust), and it
                        has made its own independent decisions to enter into
                        that Transaction and as to whether that Transaction is
                        appropriate or proper for it based upon its own judgment
                        (and in the case of Party B, also upon the judgment of
                        the Manager) and upon advice from such advisers as it
                        has deemed necessary. It is not relying on any
                        communication (written or oral) of any other party as
                        investment advice or as a recommendation to enter into
                        that Transaction; it being understood that information
                        and explanations related to the terms

                                                                               6

                        and conditions of a Transaction will not be considered
                        investment advice or a recommendation to enter into that
                        Transaction. No communication (written or oral) received
                        from any other party will be deemed to be an assurance
                        or guarantee as to the expected results of that
                        Transaction.

                (ii)    EVALUATION AND UNDERSTANDING. It is capable of
                        evaluating and understanding (on its own behalf or
                        through independent professional advice), and
                        understands and accepts, the terms, conditions and risks
                        of that Transaction. It is also capable of assuming, and
                        assumes, the risks of that Transaction.

                (iii)   STATUS OF PARTIES. No other party is acting as a
                        fiduciary or an adviser to it in respect of that
                        Transaction.

        (c)     After "Section 3(f)" in line 2 insert ",3(g), 3(h) and 3(i)".

        (d)     Insert the following new paragraphs (g), (h) and (i) in Section

                        (ii)    SOLE TRUSTEE. It has been validly appointed as

                                sole trustee of the Series Trust.

                        (iii)   NO PROCEEDINGS TO REMOVE. No notice has been
                                given to it and to its knowledge no resolution
                                has been passed, or direction or notice has been
                                given, removing it as trustee of the Series
                                Trust.

                                (A)     enter into this Agreement and the Credit

                                        to Party B.

                        (v)     GOOD TITLE. It is the lawful owner of the Assets

                application of funds held by it as trustee of the Series Trust
                being funds available for such application in accordance with
                the provisions of the Master Trust Deed and the Series

                        satisfied their respective obligations to enter into
                        such Fixed Rate Swap if the 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

                                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

                                                                              22

                        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

                        not result in a reduction, qualification or withdrawal
                        of the credit ratings then assigned by them to the
                        Securities.

                        acceptable to Moody's and sufficient to maintain the
                        credit ratings assigned to the Securities by Moody's
                        immediately prior to the review of Party A's credit
                        rating; and

                (ii)    where Party A does not have the Prescribed Rating in
                        respect

                                                                              23

                        of the Fixed Rate Swap from S&P, the greater of:

                        A.      zero;

                        B.      CR; and

                        C.      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 Monthly 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 Monthly
                                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(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 Monthly Distribution Date
                        by the relevant percentage obtained from the following
                        table:

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

                (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

                                                                              24

                        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 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 SWAPS

        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
        a 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:

                                                                              25

        (c)     (PREPAYMENT):

                (i)     on or before the last day of the Posting Period, pay to
                        Party B as a prepayment of its obligations under each
                        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;

                (ii)    in the case of the Monthly Basis Swap, on each Monthly
                        Distribution Date which follows such prepayment, pay to

                        Distribution Date held in the Basis Prepayment Balance;
                        and

                (iii)   in the case of the Quarterly Basis Swap, on each

                        prepayment, pay to Party B as a prepayment of its

        (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 each Basis Swap for the Calculation
                Period commencing on the relevant Monthly or Quarterly
                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.".

                                                                              26

(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)."

(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

                                                                              27

        33.1(b) of the Series Supplement.

                                                                              28
